The importance of flood events on the establishment of seedlings and cuttings of saltcedar (Tamarix ramosissima)
Provedor de dados: 67
Autores: Natale,Evangelina; Reinoso,Herminda.
The expansion of invasive plants is considered one of the greatest threats to biodiversity. The environments more threatened by the presence of exotic invasive species are the riparian areas due to their small surface and high diversity. The advance of Tamarix in these environments may be linked to transient conditions of higher water availability, which would allow initial colonization. The objective of the present work was to determine which hydric conditions promote germination and establishment of Tamarix cuttings by measuring in the laboratory the effects of different periods of flooding. It was observed that the germination was high under irrigation at field capacity and was decreased after 10 days of flood, while the establishment through cuttings...

Induction of somatic embryogenesis as an example of stress-related plant reactions
Provedor de dados: 69
Autores: Zavattieri,Maria Amely; Frederico,António Miguel; Lima,Mónica; Sabino,Rui; Arnholdt-Schmitt,Birgit.
In this review, we address the role of stress as one of the principal causes for a cell or tissue to change its pre-existing somatic program, reprogramming itself to express the embryogenic pathway. The focus of this paper is the effect of different stress conditions on the induction phase of plant somatic embryogenesis, as well as the development of embryogenic competence as a result of the applied stresses. We also present a variety of data that link plant somatic embryogenesis, DNA methylation and oxidative stress response.

A legume genomics resource: The Chickpea Root Expressed Sequence Tag Database
Provedor de dados: 69
Autores: Jayashree,B; Buhariwalla,Hutokshi K; Shinde,Sanjeev; Crouch,Jonathan H.
Chickpea, a lesser-studied grain legume, is being investigated due to its taxonomic proximity with the model legume genome Medicago truncatula and its ability to endure and grow in relatively low soil water contents making it a model legume crop for the study of agronomic response to drought stress. Public databases currently contain very few sequences from chickpea associated with expression in root tissues. However, root traits are likely to be one of the most important components of drought tolerance in chickpea. Thus, we have generated a set of over 2800 chickpea expressed sequence tags (ESTs) from a library constructed after subtractive suppressive hybridization (SSH) of root tissue from two closely related chickpea genotypes possessing different...

Molecular cloning and expression analysis of 12-oxophytodienoate reductase cDNA by wounding in Solanum tuberosum
Provedor de dados: 69
Autores: Díaz,Mauricio; Polanco,Victor; Ramírez,Ingrid; Peña-Cortés,Hugo.
Jasmonic acid (JA) and 12-oxophytodienoic acid (OPDA) are signal molecules involved in the stress and defense responses in plants. A full-length cDNA clon of OPR3 encoding 12-oxophytodienoate reductase 3, key enzyme involved in the biosynthesis of JA from linolenic acid was obtained from a Solanum tuberosum cDNA library. Sequence analysis showed that OPR3 encoded a polypeptide of 400 amino acids with a predicted molecular mass of 43.9 kDa and pI of 7.72. The deduced amino acid sequence of OPR3 showed high similarities to other 12-oxophytodienoate reductases. A peroxisomal signal sequence indicates OPR3 probable location in peroxisome. Levels of OPR3 mRNA accumulated in potato leaves reaching maximum levels within 1 hr of mechanical wounding. Elevated...

DAIRY PRODUCTION OF ‘SAANEN’ GOATS BASED ON METEOROLOGICAL VARIABLES AND FUTURE CLIMATE SCENARIOS
Provedor de dados: 70
Autores: Pequeno,Izaac D.; Turco,Silvia H. N.; Silva,Thieres G. F. da; Facó,Olivardo.
ABSTRACT This study aimed to modeling and bioclimatic zoning of ‘Saanen’ goat milk production in northeastern Brazil. Data were obtained from a 14-year dairy control program for 246 ‘Saanen’ goat matrices. Dairy production meteorological influence and mathematical modeling were assessed through statistical analyses such as Pearson’s correlation matrix and path analysis. Bioclimatic zoning for current and future scenarios, with climate changes, were delineated using inverse-square distance (ISD) and spherical model (kriging) interpolations. Results showed maximum air temperature to contribute substantially to goat dairy production; therefore, its modeling was based thereon. Current and future dairy production maps highlighted Maranhão and Piauí as regions...

THE USE OF VOCALIZATION SIGNALS TO ESTIMATE THE LEVEL OF PAIN IN PIGLETS
Provedor de dados: 70
Autores: Cordeiro,Alexandra F. da S.; Nääs,Irenilza de A.; Baracho,Marta dos S.; Jacob,Flávia G.; Moura,Daniella J. de.
ABSTRACT Pain is considered a condition that most affect the welfare of animals and its measurement is seen as a difficult task. This research aimed to determine the level of pain in pigs by their vocalization. It was recorded the vocalizations of 20 male piglets under normal circumstances (I), marking by Australian method (II), tail trimming management (III), and castration (IV). A unidirectional microphone and a digital recorder were used to record the sound signals. The results suggested that Pitch frequency (Hz), the maximum amplitude (Pa), and intensity (dB) increased from pain-free pigs to the marking procedure; and from marking to both tail trimming and castration The tail trimming and castration vocal response did not differ.

Identification of citrus expressed sequence tags (ESTs) encoding pleiotropic drug resistance (PDR)-like proteins
Provedor de dados: 74
Autores: Amaral,Alexandre Morais do; Saito,Daniel; Formighieri,Eduardo Fernandes; Rabello,Edenilson; Souza,Adriane N. de; Silva-Stenico,Maria Estela; Tsai,Siu Mui.
Pleiotropic drug resistance (PDR) proteins, a subfamily of the ATP-binding cassette (ABC) transporters, have been recently shown to play a role in plant defense against biotic and abiotic stresses. However, nothing is known about their expression in citrus. To investigate the occurrence of PDR homologues in citrus species, we have surveyed EST sequences from different tissues and conditions of the Citrus Expressed Sequence Tags (CitEST) database, through sequence similarity search analyses and inspections for characteristic PDR domains. Multiple sequence alignments, prediction of transmembrane topology and phylogenetic analysis of PDR-like proteins were additionally performed. This study allowed the identification of nine putative proteins showing...

Genetic changes in grapevine genomes after stress induced by in vitro cultivation, thermotherapy and virus infection, as revealed by AFLP
Provedor de dados: 74
Autores: Baránek,Miroslav; Raddová,Jana; Krizan,Bretislav; Pidra,Miroslav.
The Amplification Fragment Length Polymorphism (AFLP) technique was employed to study genetic variations which can be induced in vines by the stress occurring during different aspects of viticulture (in vitro cultivation, in vitro thermotherapy and virus infection). Analysis of AFLP banding patterns, generated by using 15 primer combinations, pointed to negligible genetic variation among plants exposed to individual stress. The average of similarity coefficients between differently stressed plants of the cultivars Müller Thurgau and Riesling were 0.984 and 0.991, respectively, as revealed by AFLP analysis. The low incidence of observed polymorphism demonstrates the high level of genome uniformity in plants reproduced by in vitro micropropagation via nodes,...

Dose única de zinco como fator moderador do estresse metabólico na desmama de bovinos de corte.
Provedor de dados: 14
Autores: MORAES, S da S.; THIAGO, L. R. L. de S.; MACEDO, M. C. M.; TORRES JUNIOR, R. A. de A.
Nos registros de fazendas de gado de corte, é notório que as maiores perdas no rebanho ocorrem no terço inicial da vida do animal. Este fato possivelmente está associado com o manejo de matrizes em pastos de baixo valor nutricional, que somado a uma suplementação mineral inadequada, predispõem os bezerros a uma deficiência subclínica de zinco (Zn). O resultado é que os bezerros produzidos nessa situação normalmente são fracos e portadores de distúrbios nutricionais que, além de influenciar os demais estados mórbidos, os tornam mais susceptíveis a doenças resultantes de um estresse prolongado. O estresse acelera o consumo de Zn e a principal conseqüência da alteração metabólica é a falta de apetite e depressão da resposta imune aos agentes agressores. A...

Transcriptomic response to parasite infection in Nile tilapia (Oreochromis niloticus) depends on rearing density
Provedor de dados: 5
Autores: Ellison, Amy R.; Uren Webster, Tamsyn M.; Rey, Olivier; Garcia De Leaniz, Carlos; Consuegra, Sofia; Orozco-terwengel, Pablo; Cable, Jo.
Background: Captive animal populations, be it for food production or conservation programmes, are often maintained at densities far beyond those in natural environments, which can have profound effects on behaviour, immune and stress levels, and ultimately welfare. How such alterations impact transcriptional responses to pathogen infection is a 'different kettle of fish' and remains poorly understood. Here, we assessed survival and gene expression profiles of infected fish reared at two different densities to elucidate potential functional genomic mechanisms for density-related differences in disease susceptibility. Results: Utilising a whole-transcriptome sequencing (RNAseq) approach, we demonstrate that rearing density in tilapia (Oreochromis niloticus)...

Determination of gender in the pearl oyster pinctada margaritifera
Provedor de dados: 5
Autores: Chavez-villalba, Jorge; Soyez, Claude; Huvet, Arnaud; Gueguen, Yannick; Lo, Cedrik; Le Moullac, Gilles.
The pearl industry in French Polynesia is based on exploitation of natural stocks of the black-lip pearl oyster (Pinctada margaritifera); it generates an annual turnover of 90 million euros. Improvements in pearl quality need genetic studies to improve the populations. This pearl oyster is a protandric species, where the sex-ratio normally is biased towards males. There is an increasing interest in gender control to find the mechanisms to augment female proportions for management purposes. This review summarizes information on exogenous and endogenous factors regulating gender in this and other bivalves and concludes that P. margaritifera is a protandric hermaphrodite, developing as a male during the first two years and without evidence of an effect from...

Physiological responses of Macoma balthica to copper pollution in the Baltic
Provedor de dados: 5
Autores: Sokolowski, A; Wolowicz, M; Hummel, H; Bogaards, R.
Physiological and behavioral responses to Cu exposure were measured in the Baltic clam Macoma balthica from the Gulf of Gdansk, southern Baltic Sea. The burrowing activity, mortality rate, glycogen content, condition index and free amino acid (FAA) composition were analysed as indicators of stress in a series of field and laboratory studies. M. balthica exposed to Cu showed clear Cu-concentration related differences in burrowing activity and mortality rate, but no consistent differences in the condition index, glycogen content, and free amino acids. The clams from a less polluted area reacted more strongly and were more sensitive to additional stress as compared to organisms from a more polluted region. The effect of Cu on the ecophysiology of Baltic clams...

Le risque thermique : caractérisation des environnements thermiques des 3 sites atliers de MOREST en lien avec les mortalités observées sur le terrain
Provedor de dados: 5
Autores: Ropert, Michel; Rauflet, Fabienne; Soletchnik, Patrick; Geairon, Philippe; Bedier, Edouard; Bouget, Jean-francois.
Temperature affects undoubtedly the 3 working sites where, systematically, the observation of the first abnormal mortalities coincides with a water temperature of around 19°C. The nature of the processes implied could have a "cumulative" effect, affecting the physiology (this phenomenon has been observed with other marine species) or a "threshold" effect, acting only as a trigger. The question has not been answered yet. The kinetics of the thermic evolution around the mortality period has to be studied in depth in order to understand if this temperature acts more as an "associated factor", during a chronic stress period, or during an acute stress, as suggested by the "on-bottom/off bottom" mortality model of the Marennes Oléron Bay [12].

In 2008, we published the first set of guidelines for standardizing research in autophagy. Since then, this topic has received increasing attention, and many scientists have entered the field. Our knowledge base and relevant new technologies have also been expanding. Thus, it is important to formulate on a regular basis updated guidelines for monitoring autophagy in different organisms. Despite numerous reviews, there continues to be confusion regarding acceptable methods to evaluate autophagy, especially in multicellular eukaryotes. Here, we present a set of guidelines for investigators to select and interpret methods to examine autophagy and related processes, and for reviewers to provide realistic and reasonable critiques of reports that are focused on...

Characterization and variations of organic parameters in teleost fish endolymph during day-night cycle, starvation and stress conditions
Provedor de dados: 5
Autores: Guibbolini, M; Borelli, G; Mayer Gostan, N; Priouzeau, F; De Pontual, Helene; Allemand, D; Payan, P.
The aim of the present work was to examine the modifications of the organic composition of fish endolymph under environmental conditions (day-night cycle, starvation and Cl-2-Stress) known to modify otolith growth. Endolymph electrophoretic patterns were compared. An antibody raised against the trout otolith organic matrix allowed examining the variations of organic matrix precursors in the endolymph under the above conditions. Western blot analysis showed bands around 60-80 kDa. A 50% decrease of immunolabelling was observed during the night whereas increases were seen after starvation (factor 3) or stress (factor 2) suggesting that these variations could be related to the organic matrix deposit. A factor retarding in vitro CaCO3 crystallization (FRC) was...

Diatoms adapt to changing environmental conditions in very efficient ways. Among the mechanisms that can be activated, the reorientation of carbon metabolism is crucial because it allows the storage of energy into energy-dense molecules, typically lipids. Beside their roles in physiology, lipids are commercially interesting compounds. Therefore studies dealing with this topic are relevant for both basic and applied science. Although the molecular mechanisms involved in the reorientation of carbon metabolism as a response to a deficiency in nutrients such as nitrogen or phosphorus has been partially elucidated, the impacts of carbon availability on the implementation of the reorientation mechanisms remain unclear. Indeed, it has not been determined if the...

Acumulación de ácido araquidónico en fosfolípidos y triglicéridos y producción de prostaglandinas con relación a estrés térmico en semilla de ostión Crassostrea gigas
Provedor de dados: 5
Autores: Duran Encinas, Yazmin.
Crassostrea gigas is a marine invertebrate that inhabits the intertidal zone and therefore, is commonly exposed to multiple environmental stressors, including temperature. In recent years mass mortality events have been reported in Mexico in C. gigas associated with the increase in temperature during the summer. Organisms under thermal stress present an increase in prostaglandins (PG) production by cyclooxygenases (COX), an enzymatic route using arachidonic acid (ARA) present in the phospholipids (FL) of the cell membrane as substrate, but PG can also increase non-enzymatically by reactive oxygen species (ROS) that are produced during increased metabolism. It has been reported that some organisms exposed to stress accumulate a higher concentration of ARA...

Husbandry stress during early life stages affects the stress response and health status of juvenile sea bass, Dicentrarchus labrax
Provedor de dados: 5
Autores: Varsamos, S; Flik, G; Pepin, Jean-francois; Bonga, S; Breuil, Gilles.
In aquaculture management it is important to establish objective criteria to assess health and welfare of the fish. Here we show that European sea bass (Dicentrarchus labrax) confronted with husbandry-associated stress (tank cleaning, i.e. scrubbing, and water temperature variation) during early life stages show poorer survival and disease resistance as juveniles. We evaluated several parameters for stress (plasma cortisol, glucose and lactate, hydromineral status), growth performance, the immune response (plasma IgM levels) and the effects of a nodavirus challenge. Principal component analysis allowed the establishment of a stress panel including plasma cortisol, osmolality, IgM levels and weight. Sea bass juveniles reared during early life in high and...

This study aims to shed light on corticosteroid regulation of stress in teleost fish with focus on the corticosteroid signalling system. The role of the mineralocorticoid-like hormone 11-deoxycorticosterone (DOC) in fish is still enigmatic, as is the function of the mineralocorticoid receptor, MR. Low plasma DOC levels and ubiquitous tissue distribution of MR question the physiological relevance of the mineralocorticoid-axis. Furthermore, the particular purpose of each of the three corticosteroid receptors in fish, the glucocorticoid receptors, GR1 and GR2, and the MR, is still largely unknown. Therefore we investigate the regulation of cortisol and DOC in plasma and mRNA levels of MR, GR1 and GR2 in the HPI-axis tissue (hypothalamus, pituitary and...

Autores: Baleux, B; Caro, A; Lesne, J; Got, P; Binard, S; Delpeuch, B.
The release of enteric pathogenic bacteria in aquatic environments poses the problem of the fate of these bacteria under the effects of environmental factors (solar radiation, salt concentration, temperature, nutrient level, pH, competition). Frequently, these bacterial cells, potentially pathogenic, enter into a non-culturable state on routine bacteriological plating media. However, the use of direct detection methods (DAPI stained cells) allows the visualization of these Viable but Non Culturable cells (VNC). But, beyond the characterization of the viability of the cells (electron transport activity, metabolic activity, membrane integrity, structure and/or quantity of DNA), what happens with the virulence of these cells? This problem was experimentally...

Effects of hypoxia and elevated ammonia concentration on the viability of red snapper embryos and early larvae
Provedor de dados: 5
Autores: Bardon-albaret, Agnes; Saillant, Eric.
The effects of hypoxic conditions and elevated ammonia concentrations on the viability of embryos and newly hatched larvae of the red snapper (Lutjanus campechanus) were investigated. In all experiments, tested levels of hypoxia or ammonia concentrations were applied to embryos and unfed newly hatched larvae from three different spawns. Exposures began at 1 h post fertilization (pf) and lasted until all individuals in a group had expired. Survival rates were monitored daily in duplicates for each spawn in each treatment. Fertilized eggs exposed to 2 mg L− 1 dissolved oxygen (29% saturation) showed complete mortality before hatch while 81% of embryos in control groups (&gt; 85% saturation) hatched and subsequently maintained high survival until 5 days pf....

Autores: Cochard, Jean-claude.
Les crevettes pénéides maintenues captives dans des cages posées sur le fond des bassins d'élevage subissent un stress dû au sédiment qui peut être évalué par la comparaison entre la valeur de la pression osmotique de leur hémolymphe et celle des crevettes libres du même bassin. Les objectifs des travaux réalisés à la station de Saint-Vincent (SASV, Nouvelle Calédonie) étaient de confirmer la variabilité spatiale de l'intensité du stress et de rechercher dans les sédiments un indicateur physique ou chimique corrélé à ce stress. Des lots de 25 à 30 crevettes de 13,2g, pêchées à l'épervier, ont été placés dans des cages de grillage métallique déposées en 12 points du bassin d'élevage. Les cages ont été relevées au bout de 24 heures et la pression osmotique...

Some methods for quantifying quality in the scallop Pecten maximus (L.)
Provedor de dados: 5
Autores: Maguire, Julie A.; Fleury, Pierre-gildas; Burnell, Gavin M.
(Not controled OCR) Because biological systems do not work in isolation, behavioral, biochemical, and physiological tests can give an overview of an individual's vital processes and reaction to stress. Two stress gradients were applied in this study, a short acute desiccation stress and a long-term density stress. These stress gradients were used to assess the usefulness of various techniques for quality assessment: namely, a standard salinity stress test, condition index, recessing speed of the scallop, adenylic energetic charge (AEC). and percentage carbohydrate content of the striated muscle. The results showed that AEC could be used effectively to measure the effect of a short-term stress. In the striated muscle. AEC levels were useful in...

Adaptative responses of E-coli to marine environmental stresses. a modelling approach based on viability and dormancy concepts
Provedor de dados: 5
Autores: Martin, Y; Troussellier, Marc; Bonnefont, Jl.
In an attempt to synthesize conceptual and experimental information on the behaviour of enteric bacteria in seawater, a mathematical model has been developed. This model is based on changes in intracellular metabolisable components depending an physiological responses of the cell when subjected to nutrient starvation, salinity stress and solar radiation. Following a strategy which takes into account short- and mid-term physiological adaptation and reversal processes, the cells can develop in different states: culturable (B-1), viable and definitively nonculturable (B-2), and reversibly dormant (B-3) cells. Model parameters were deduced either from original microcosm experiments, from literature data or calibration procedures. Validation of the model was...

Summer mortality of Pacific oysters is known in several countries. However no specific pathogen has been systematically associated with this phenomenon. A complex combination of environmental and biological parameters has been suggested as the cause and is now starting to be identified. A high genetic basis was found for survival in oysters when a first generation (G1) was tested in three sites during summer. This paper presents a synthesis on physiological characteristics of two selected groups ('R' and 'S', from families selected for resistance and susceptibility to summer mortality respectively), of the second and third generations. R and S showed improvement or reduction of survival compared with the control in both field and laboratory trials...

Physiological response of the blue shrimp Litopenaeus stylirostris to short-term confinement on a pond bottom
Provedor de dados: 5
Autores: Mugnier, Chantal; Lemonnier, Hugues; Legrand, Alexandre.
The blue shrimp Litopenaeus stylirostris was exposed to pond sediment for 48 h and its physiological response was studied in relation to molt stage. Shrimp were maintained in cages within a semi-intensive pond after 4 months of rearing. Hypoosmoregulatory capacity (hypo-OC), magnesium ions (Mg ions), glucose, total proteins and oxyhaemocyanin were assayed in haemolymph. An increase of 370% to 500% in Mg ions concentration and 200% to 266% in glucose concentration, and a decrease in hypo-OC in shrimp maintained close to the centre of the pond indicated a short-term stress response in all molt stages. Indicators of water and sediment pore water quality were within normal operating limits, however this area was characterized by high water content and...

Influence of sediment characteristics on shrimp physiology: pH as principal effect
Provedor de dados: 5
Autores: Lemonnier, Hugues; Bernard, E; Boglio, E; Goarant, Cyrille; Cochard, Jean-claude.
Penaeid shrimp reared in earthen ponds are exposed to sediment, which can, in some instances, induce a stress. In seawater, the osmoregulatory capacity (hyporegulation) is a useful tool to compare the physiological condition of shrimp exposed to various stressors. By keeping some shrimp in cages at different locations of a single pond heterogeneous in terms of sediment quality, it was possible, using osmotic pressure (OP), to identify some locations where the stress was maximum and some others where it was minimum. Simultaneously, sediment samples were taken and analysed in order to evaluate some physico-chemical parameters that could be related to the stress observed in the shrimps kept in the cages. This approach allowed to show a significant positive...

Autores: Cochard, Jean-claude; Goarant, Cyrille; Boglio, Eric; Lemonnier, Hugues.
The influence of the soil quality of culture pond on the physiological state of Penaeus stylirostris reared in earthen shrimp pond in New Caledonia was investigated by the measurement of the osmoregulatory capacity and magnesium hemolymph concentration of samples of 20 of these shrimp captured in the pond and maintained for 24 or 48h in cages laid on the bottom. A first experiment was affected by the occurrence of a pathology caused by Vibrio penaeicida probably due to initial handling stress. The second experiment showed that the osmoregulatory capacity is depresssed as a function of the soil quality : the more it is reduced the more the depression is important.

Interactions entre traits de personnalité des téléostéens, environnement et polluants
Provedor de dados: 5
Autores: Alfonso, Sebastien.
In the frame of this thesis, we first studied the establishment of personality in teleost, the consistency across context and different life stages as well as the associated physiological mechanisms. Personality appeared consistent across contexts over a short time period but it was no longer the case over a long period of time, especially between different life stages. Physiological mechanisms of stress regulation, as well as activity and neural plasticity, differed according to individual boldness. Then, we studied the physiological and behavioural responses of teleost fish chronically exposed to an environmentally relevant mixture of POP (PCBs and PBDEs), as well as those of their unexposed offspring. Different behavioural alterations in larval...

Response of the blue shrimp Litopenaeus stylirostris to temperature decrease and hypoxia in relation to molt stage
Provedor de dados: 5
Autores: Mugnier, Chantal; Soyez, Claude.
The effect of different levels of dissolved oxygen (DO) and a decreased temperature combined with severe hypoxia were studied in the blue shrimp Litopenaeus stylirostris in relation to molt stage. In the first experiment, shrimps were submitted to DO concentrations of 5 to 1 mg l(-1). Osmoregulatory capacity (OC) was measured in shrimps at molt stage C after 6, 24, or 48 h of exposure. No mortality was recorded but a significant negative effect of DO concentration on hypo-OC was observed for DO concentrations below 3 mg l(-1). Osmoregulation improved after 48 h exposure, compared to 6 and 24 h exposure.   In a second experiment, temperature was decreased from 28 to 22 degreesC in 24 h, before a severe hypoxia of 0.5+/-0.1 mg O-2 l(-1) was applied....

Spatial distribution and activity patterns as welfare indicators in response to water quality changes in European sea bass, Dicentrarchus labrax
Provedor de dados: 5
Autores: Alfonso, Sebastien; Sadoul, Bastien; Cousin, Xavier; Bégout, Marie-laure.
In aquaculture, fish are exposed to unavoidable stressors that can be detrimental for their health and welfare. However, welfare in farmed fish can be difficult to assess, and, so far, no standardized test has been universally accepted as a welfare indicator. This work contributes to the establishment of behavioural welfare indicators in a marine teleost in response to different water quality acute stressors. Groups of ten fish were exposed to high Total Ammonia Nitrogen concentration (High TAN, 18 mg.L-1), Hyperoxia (200 % O2 saturation), Hypoxia (20 % O2 saturation), or control water quality (100% O2 saturation and TAN &lt; 2.5 mg.L-1) over 1 hour. Fish were then transferred in a novel environment for a group behaviour test under the same water quality...

During 84 days, the effects of density on juvenile sea bass (Dicentrarchus labrax) (76 +/- 16 g) were studied in an experimental tank-based flow through system. Performance, stress response and resistance to virus infection were analysed under five stabilized rearing densities: 10, 20, 40, 70 and 100 kg m(-3). Water quality parameters (CO2, total ammonia nitrogen and O-2) were measured and maintained close to the recommended values for farmed sea bass by adjusting water renewal exchange. No significant differences were observed between density treatments, neither on stress response (cortisol) nor susceptibility to nodavirus. With regards to biological performances, the daily feed intake and specific growth rate were significantly lower in fish reared at...

Measuring cortisol, the major stress hormone in fishes
Provedor de dados: 5
Autores: Sadoul, Bastien; Geffroy, Benjamin.
Stress in teleosts is an increasingly studied topic because of its interaction with growth, reproduction, immune system and ultimately fitness of the animal. Whether it is for evaluating welfare in aquaculture, adaptive capacities in fish ecology, or to investigate effects of human‐induced rapid environmental change, new experimental methods to describe stress physiology in captive or wild fish have flourished. Cortisol has proven to be a reliable indicator of stress and is considered the major stress hormone. Initially principally measured in blood, cortisol measurement methods are now evolving towards lower invasiveness and to allow repeated measurements over time. We present an overview of recent achievements in the field of cortisol measurement in...

Disturbance induced decoupling between host genetics and composition of the associated microbiome
Provedor de dados: 5
Autores: Wegner, Karl Mathias; Volkenborn, Nils; Peter, Hannes; Eiler, Alexander.
Background  Studies of oyster microbiomes have revealed that a limited number of microbes, including pathogens, can dominate microbial communities in host tissues such as gills and gut. Much of the bacterial diversity however remains underexplored and unexplained, although environmental conditions and host genetics have been implicated. We used 454 next generation 16S rRNA amplicon sequencing of individually tagged PCR reactions to explore the diversity of bacterial communities in gill tissue of the invasive Pacific oyster Crassostrea gigas stemming from genetically differentiated beds under ambient outdoor conditions and after a multifaceted disturbance treatment imposing stress on the host. Results  While the gill associated microbial communities in...

Energetic adjustments in freely breeding-fasting king penguins: does colony density matter?
Provedor de dados: 5
Autores: Viblanc, Vincent A.; Saraux, Claire; Malosse, Nelly; Groscolas, Rene.
1. For seabirds that forage at sea but breed while fasting on land, successful reproduction depends on the effective management of energy stores. Additionally, breeding often means aggregating in dense colonies where social stress may affect energy budgets.  2. Male king penguins (Aptenodytes patagonicus) fast for remarkably long periods (up to 1 center dot 5months) while courting and incubating ashore. Although their fasting capacities have been well investigated in captivity, we still know very little about the energetics of freely breeding birds.  3. We monitored heart rate (HR, a proxy to energy expenditure), body temperature and physical activity of male king penguins during their courtship and first incubation shift in a colony of some 24000 freely...

A comprehensive research program has been developed since 1995 to focus on C. gigas abnormal mortality rates occurring regularly during the summer period in the Bay of Marennes Oleron (France). Several subprojects were carried out including in-vitro ecophysiological studies to asses l) the relationship between reproductive status, scope for growth and mortality, 2) effects of stress temperature on physiological functions. Meanwhile, field studies concerned monitoring surveys of calibrated oyster populations at various emersion time and geographic sites. A database was developed and incorporated into a geographic information system (GIS) to overlay several layers of information and establish relationship among environmental parameters and mortality rates....

Combined effect of external ammonia and molt stage on the blue shrimp Litopenaeus stylirostris physiological response
Provedor de dados: 5
Autores: Mugnier, Chantal; Justou, Carole.
The effect of ambient ammonia and molt stage on the physiological response of the blue shrimp Litopenaeus stylirostris was studied. Shrimps were submitted to 54.6 mg l(-1) ammonia-N (1.76 mg l(-1) NH3-N) for 24 h. Only shrimps in stages C, D-0, D-1 and D-2 were used for the analysis. Haemolymph was assayed for osmoregulatory capacity (OC), magnesium ion (Mg ion), total proteins, oxyhaemocyanin, lactate and glucose. Molt stage had an effect on OC, Mg ion and total proteins in control shrimps, and on OC, Mg ion and lactate in treated animals. Ammonia treatment decreased OC and lactate, and increase Mg ion concentration in haemolymph, for all molt stages. It decreased significantly total proteins and oxyhaemocyanin for stages D-1 and D-2, and increased...

Autores: Philippe, Régis.
Le transfert en mer de post-larves de coquille Saint-Jacques depuis la nurserie, à terre, jusqu'à la station de prégrossissement, en mer, provoque de faibles survies : 20 à 50 % L'étude du passage en mer montre 2 stress élémentaires principaux : la dé-fixation des post-larves et leur émersion pendant le transport (l'effet des chocs thermiques n'a pas été étudié ici). Quelques comparaisons de lots de post-larves dé-fixées ou émergées, montrent que la cause principale de mortalité serait la dé-fixation. La dernière partie de cette étude aborde des essais de transfert sans dé-fixation, à l'aide de supports-collecteurs immergés pendant l'élevage post-larvaire. Les survies au passage en mer apparaissent beaucoup plus satisfaisantes (64 à 100 % dans la plupart...

Mortality among juvenile Crassostrea gigas has been occuring during the summer months since 1995 and is now considered to be a real problem for French oyster culture. The aim of this study was to standardise the stress that could be applied to Crassostrea gigas spat. In initial experiments in 1998, the weight of individual spat and the duration of a heat shock at 50°C in freshwater, adapted for oysters of between 500 and 2000 mg, were built into a model to obtain 50% mortality. However, the precision was low (50%) and will need to be improved in the future. Following this, hatchery-produced juveniles weighing 10 to 500 mg were subjected to heat shock at 45°C in heshwater ; the duration of the shock was calculated based on a model built in 1997. The results...

Stress enhances or inhibits neurogenesis in mammals and some fish species. The link between the two processes is still unclear. Most studies have been performed in very specific stressful or altered environments. Despite the known inter-individual divergence in coping abilities within populations, the relationship between the stress axis and neurogenesis has never been addressed in unstressed individuals. Here we correlate brain expression of the pcna (proliferating cell nuclear antigen) and neurod1 (neurogenic differentiation factor 1) genes, two markers of neurogenesis, with transcripts of cortisol receptors in three fish species living in very distinct environments. Within the three species, individuals with the highest expression of neurogenesis genes...

Autores: Strubbia, Sofia; Lyons, B. P.; Lee, R. J.
Environmental conditions and xenobiotic exposure can be sources of stress to living organisms. Biological markers are measurable indicator of changes which may happen at any biological level and which can be considered an early warning signal of some biological or environmental state or condition. A structured field study was undertaken to investigate the relationship between three biomarker assays and the spatial and temporal variation of each biomarker in samples of Mytilus edulis. The three biomarkers were the neutral red retention assay, micronucleus assay and comet assay, which indicate damage at different cellular/molecular levels. Three sites in Poole Harbour, an area on the South coast of the UK were sampled on six separate occasions at least three...

Interest in bivalve genomics has emerged during the last decade, owing to the importance of these organisms in aquaculture and fisheries and to their role in marine environmental science. Knowledge of bivalve genome structure, function and evolution resulting from 20th century "single gene" approaches is limited, but genomic technologies are called to dramatically increase it. Research based on linkage maps, transcriptomics and proteomics is being carried out to study the genetic and molecular bases of traits of interest in bivalve farming industry, mainly disease susceptibility, tolerance to environmental stress, and growth. The Pacific oyster (Crassostrea gigas) is now the focus of an international genome-sequencing consortium. The use of bivalves in...

Considering the size of some nuclei and area, sex hormones control the sexual development of the brain. The sexual development of the brain can also be influenced by environmental stress. This study aimed to clear the effect of prenatal water deprivation on the development of sexual dimorphic nucleus (SDN) of the brain. In this research, pregnant rats were divided into two groups (control and treated). For the treated animals, water was removed from the ewes for 48 h at the end of third trimester of gestation (19-21 days). TUNEL staining was used for detection of apoptosis in paraffin embedded diencephalon selected sections. The ratio of apoptotic cells to non- apoptotic ones was calculated as apoptotic index. Differences of apoptotic index and serum...

ABSTRACT Anesthetic effect of Aloysia triphylla and Lippia alba essential oils (EOs) in the Amazonian fish Serrasalmus eigenmanni was evaluated. The fish were placed in aquaria containing A. triphylla or L. alba EOs (25 to 200 µL L-1). Then, fish were transferred to aquaria containing EO-free water to evaluate their recovery time. In another experiment, fish were transferred to aquaria containing A. triphylla or L. alba EOs (3 to 10 µL L-1) and swimming behavior was analyzed for up to 240 min of exposure. Water samples were collected at 0 and 240 min and blood samples were collected at 240 min. Tested concentrations induced all stages of anesthesia, except 25 µL L-1 A. triphylla EO and 50 µL L-1 L. alba EO, which only induced sedation. Prolonged exposure...

The aim of this study was to identify the times of anesthetic induction and recovery in slender seahorses (Hippocampus reidi) that were exposed to the essential oil of Lippia alba (EO), as well as the efficacy of EO as a stress-reducing agent in the transport of this species. Slender seahorses were placed in 1-L aquaria containing different concentrations of EO (0, 10, 20, 50, 150, 300 and 450 µL L-1), and after induction, fish were transferred to aquaria that were free of anesthetic to evaluate their recovery time. In an additional experiment, slender seahorses were transported in plastic bags with 15 µL L-1 of EO for 4 or 24 h. The increased concentration of EO proportionally decreased the time required for the induction of anesthesia. EO treatment (15...

This study analyzed the chemical composition and anesthetic potential of essential oil (EO) of Nectandra megapotamica in fat snook (Centropomus parallelus). For the extraction of EO by hydrodistillation, leaves were separated in young (EO-Y) or old (EO-O), and the chemical composition of the EOs was determined by CG-MS. The anesthetic potential was assessed by the evaluation of induction and recovery time of anesthesia and stress response from anesthesia and transport. Three experiments were carried out: i) four different concentrations of each EO were tested to evaluate anesthesia induction and recovery time; ii) two concentrations of EO-O were tested for the evaluation of its effects on stress parameters (glucose, lactate, and Na+ and K+ plasma levels)...

Autores: Carneiro,Paulo César Falanghe; Kaiseler,Pedro Henriques da Silva; Swarofsky,Elaine de Azambuja Correia; Baldisserotto,Bernardo.
Fish transportation is a common practice on fish farms and is considered to be a stressor that could negatively affect fish health. The objective of this study was to evaluate several physiological responses of stress in jundiá caused by transport at different loading densities. Jundiá juveniles were placed in plastic bags on a mechanical transport simulator for four hours at four different loading densities (75, 150, 250 and 350 g L-1) and then transferred to sixteen 80-L plastic boxes for 96 hours after transport. Water samples were collected before and after transport to measure dissolved oxygen, temperature, pH and ammonia levels. Blood samples were taken at departure and arrival, as well as at 24 and 96 hours after transport to monitor cortisol,...

There is an increasing demand for inexpensive and safe anesthetics that can reduce fish stress caused by some procedures such as capture and handling. In this context, the present study evaluated the potential of essential oils (EO) of three Brazilian native plants (Hesperozygis ringens, Lippia sidoides and Ocotea acutifolia) as anesthetics for the silver catfish - Rhamdia quelen. Moreover, an analysis was made of the chemical composition of these oils and their influence on stress parameter. EO of H. ringens and O. acutifolia were effective as anesthetics, without behavioral side effects. EO of O. acutifolia (150 µL L-1) promoted an increase in blood glucose level. Regarding to the composition, pulegone accounts for 96.63% of the EO of H. ringens, and...

初めて搾乳を行う 5人の搾乳未経験者が搾乳した日乳量は、搾乳経験者が搾乳した日乳量に比べて減少することが示された。それは搾乳未経験者が搾乳牛に緊張やストレスを与えたためと考えられた。また搾乳未経験者は搾乳準備時間が手間取るため長くなり、そのことが残乳を増やしたと思われ、日乳量の減少につながったと考えられた。ミルカーをつける直前の搾乳準備時の搾乳牛心拍数を、搾乳前安静時と比べた心拍変動率で表した。搾乳未経験者の搾乳経験回数の増加に伴って、心拍変動率に５頭全頭における一定の変化パターンは見られなかったが、搾乳準備時間の短い牛では、心拍変動率が有意に減少した（P&lt;0.05）。同じ搾乳施設では未経験者の搾乳回数が増加するにつれて、搾乳準備時間は減少し、その時間帯の乳牛の肢上げと蹴り行動も減少した。搾乳施設が代わるとまた未経験者の搾乳準備時間が長引く傾向がみられた。以上から、搾乳未経験者は搾乳牛にストレスや緊張を与えて肢上げや蹴り行動が増加し、心拍変動率が有意に増加し（P&lt;0.05）、その結果日乳量の減少をもたらした。しかし累積搾乳回数の増加に従い、肢上げや蹴り行動が減少し搾乳準備時間も短くなり、心拍変動率も下がることを示した。

Impacts of food-based enrichment on behaviour and physiology of male greater rheas (Rhea Americana, Rheidae, Aves)
Provedor de dados: 84
Autores: Lima,Márcia Fontes Figueiredo; Azevedo,Cristiano Schetini de; Young,Robert John; Viau,Priscila.
Abstract Distress can be defined as a biological response of an individual to long-term threats to its homeostasis and it should be avoided from an animal welfare perspective. High levels of stress hormones and the expression of abnormal behaviours are responses normally observed in distressed animals. Captive environments can provoke distress, especially when inappropriate stimuli are provided to the animals. The concomitant use of behavioural and non-invasive hormonal measures is a means to evaluate captive animal welfare. Environmental enrichment is a tool that can reduce distress and minimize the expression of abnormal behaviour in captive animals. The aim of this study was to evaluate greater rheas’ responses (behavioral and hormonal) to food-based...

The objective of this work was to characterize the hematological profiles of steers and bulls, according to residual feed intake (RFI), after feed deprivation. Twenty‑month‑old Nellore steers and bulls were fed feedlot diets for 70 and 56 days, respectively. RFI was calculated as the difference between actual feed intake and expected feed intake. More and less efficient steers and bulls, according to RFI, were subjected to 24 hours of food deprivation. Blood was sampled prior to and following the withdrawal period. Hematological analyses included total and differential white blood cell count, red blood cell count and morphology, and plasma glucose concentration. Variation in RFI did not influence plasma glucose concentration or blood cell profiles. Glucose...

Effects of pre-slaughter fasting on broiler welfare, meat quality, and intestinal integrity
Provedor de dados: 89
Autores: Pereira,REP; Martins,MRFB; Mendes,AA; Almeida,PAZ ICL; Komiyama,CM; Milbradt,EL; Fernandes,BC da S.
The Brazilian Ministry of Agriculture (MAPA) regulations establish 12 hours as the maximum pre-slaughter fasting period for broilers; however, many processing plants have considered this time is not sufficient, and consequently return the birds to the farms, with consequent economic losses and welfare problems. Therefore, it is necessary to investigate the possible effects of longer pre-slaughter fasting times. The objective of the present study was to evaluate the effect of pre-slaughter fasting times longer than those established by MAPA on broiler welfare, breast meat quality, and intestinal integrity. Forty 42-d-old broilers were submitted to different pre-slaughter fasting times: group I: 6 hours, group II 9h, group III 12h, and group IV 15h. Bird...

ABSTRACT The objective of this study was to evaluate menthol and eugenol as anesthetics for early juveniles of curimba, Prochilodus lineatus. Juveniles of 4.0±0.5 g and a total length of 8.8±0.1 cm were exposed to the anesthetics menthol (20, 30, 40, 50, 60, 70, and 80 mg L−1) and eugenol (20, 30, 40, 50, 60, and 70 mg L−1) up to deep anesthesia. The anesthetic effects were evaluated measuring the induction time to deep anesthesia (characterized by loss of equilibrium, absence of swimming, reduction of opercular movements, and responses only to intense tactile stimuli), recovery time, time to appetite return, and mortality rate after 96 h of procedure. The concentrations between 60 to 80 mg of menthol L−1 provided the lowest time of induction. Increased...

Autores: Reis-Silva, Thiago; Lima, Ana Paula; Moreira, Natalia; Calefi, Atilio; Sandini, Thaísa Meira; Florio, Jorge Camilo; Bernardi, Maria Martha.
High and low immobility on the tail suspension test is a common tool for assessing antidepressant drug effects. However, those parameters might be a natural phenotype present in the mice population and could be selected through behavior evaluation without an induced-drug behavior need. High immobility has been also related to depressed-like behavior, that in humans are characterized by wide range of symptoms, such as anhedonia, anxiety and tiredness.

Differences in wing melanization and pigmentation pattern in Drosophila buzzatii (Diptera: Drosophilidae) under chemical stress
Provedor de dados: 99
Autores: Mongiardino Koch,Nicolás; Hasson,Esteban; Soto,Ignacio M.
Recently, the genetic basis and developmental mechanisms underlying the process of melanization have become progressively elucidated, allowing us to study the evolutionary processes that govern the huge variability of pigmentation observed in nature. However, environmental factors contributing to such variability have received little attention, even though they might have profound ecological consequences. Here we describe a method for analyzing the wing melanization patterns of drosophilids in both qualitative and quantitative ways. We test this method on wings of Drosophila buzzatii Patterson &amp;amp; Wheeler individuals, reared in control and alkaloid-enriched mediums. The alkaloids were extracted from the secondary host of these flies, Echinopsis...

Selection methods for maize seedlings in greenhouse as related to aluminum tolerance
Provedor de dados: 63
Autores: Giaveno,Carlos Daniel; Miranda Filho,José Branco de.
Genetic improvement is a useful approach to increase aluminum tolerance in maize. This experiment was carried out to compare two screening techniques under greenhouse conditions and estimate the association between the results obtained for both bioassays with grain yield. Nutrient solution (NS) and pots with acid soil (AS) were utilized as screening methodologies to perform one cycle of divergent selection for aluminum tolerance in the tropical maize population SIKALQ. The four sub-populations obtained by both approaches were compared with the original and checks in a greenhouse and in multilocation field trials. Evaluation under the conditions of NS and AS showed that the populations with the best performances were those selected for aluminum tolerance...

Provedor de dados: 63
Autores: González,María-Rosa; Hailemichael,Girma; Catalina,Álvaro; Martín,Pedro.
ABSTRACT: Although water deficit and iron deficiency chlorosis are common environmental stresses in the Mediterranean area, few data are reported in the literature on their effects on vineyards, when acting simultaneously. The main objective of this research was to study the combined effects of iron deficiency and water status on vigor, yield and fruit composition in rainfed vineyards. Moreover, the investigation aimed to evaluate the feasibility of using foliar chlorophyll content (Chl) and predawn leaf water potential (LWP), measured at veraison, to assess potential quality of grapes in the framework of precision viticulture. For this, 24 non-irrigated ‘Tempranillo’ vineyard subzones were monitored in Ribera del Duero (North-Central Spain) during three...

Provedor de dados: 63
Autores: Ozório,Rodrigo; Van Ginneken,Vincent; van den Thillart,Guido; Verstegen,Martin; Verreth,Johan.
Lipids, together with proteins, are traditionally considered as primary fuels during aerobic swimming. The effects of dietary fat and carnitine supplements and exercise on the energy metabolism of juvenile fish were investigated. One hundred African catfish (Clarias gariepinus) were fed four isonitrogenous diets containing a fat level of 100 or 190 g kg-1 diet and one of the two levels of carnitine (15 and 1000 mg kg-1). Fish grew from 61 to 162 g in 10 wk. Thereafter, 6 fish per group swam vigorously for 3 h and the results were compared with unexercised groups. Fish receiving 1,000 mg carnitine accumulated 2- to 3-fold more carnitine than fish receiving 15 mg carnitine. Plasma acyl-carnitine level was affected by an interaction between dietary treatment...

Plant biostimulants: physiological responses induced by protein hydrolyzed-based products and humic substances in plant metabolism
Provedor de dados: 63
Autores: Nardi,Serenella; Pizzeghello,Diego; Schiavon,Michela; Ertani,Andrea.
ABSTRACT In recent years, the use of biostimulants in sustainable agriculture has been growing. Biostimulants can be obtained from different organic materials and include humic substances (HS), complex organic materials, beneficial chemical elements, peptides and amino acids, inorganic salts, seaweed extracts, chitin and chitosan derivatives, antitranspirants, amino acids and other N-containing substances. The application of biostimulants to plants leads to higher content of nutrients in their tissue and positive metabolic changes. For these reasons, the development of new biostimulants has become a focus of scientific interest. Among their different functions, biostimulants influence plant growth and nitrogen metabolism, especially because of their...

Performance of juvenile turbot (Scophthalmus maximus) fed varying dietary L-carnitine levels at different stocking densities
Provedor de dados: 63
Autores: Gonçalves,José Fernando Magalhães; Turini,Bruno Graziano da Silva; Ozório,Rodrigo Otávio de Almeida.
Commercial farming of turbot (Scophthalmus maximus) at high stocking densities may lead to growth depression and increasing production costs. Moreover, the high levels of accumulated waste in an intensive system may cause rapid deterioration of water quality, which may undermine the production. L-carnitine is known as a growth-enhancer which shows promise as mitigator of crowding effects. The effects of stocking densities (4, 8, 11 and 14 kg m²) on growth performance, feed utilization and body composition were evaluated during 75 days on turbot (75.6 ± 2.8 g) fed two dietary L-carnitine levels (40 or 240 mg kg¹). At the end of the feeding trial, total ammonia excretion (TAN) was measured postprandially for 24h. Specific growth rate and weight gain...

Autores: Gomes,Levy de Carvalho; Roubach,Rodrigo; Cavero,Bruno Adan Sagratzki; Pereira-Filho,Manoel; Urbinati,Elisabeth Criscuolo.
This study examined the stress response of pirarucu juveniles in a closed system transport. Pirarucu (Arapaima gigas) is a native Amazonian fish species from the Osteoglossidae family and an obligated air breather. A short duration transport trial (6h) was undertaken comparing closed polyethylene bags filled with atmospheric air (Air group) and bags filled with pure oxygen (Oxi group). Dissolved oxygen was the only water parameter that presented a difference between fish groups, and was saturated in the oxi group as expected. There was no mortality in either group after transport. Fish feeding was observed 36 h after transport for all fish, and normal feeding consumption was observed at 72 h. In both groups physiological responses were similar. Cortisol...

Provedor de dados: 36
Autores: Gomes,Levy de Carvalho.
Pirarucu (Arapaima gigas) is an obligatory air-breathing fish from the Amazon basin. Previous study showed that pirarucu juveniles present a latency period in their response to moderate stress (transportation). Therefore the objective of this study was to verify the effects of a prolonged air exposure stress in lactate, glucose, cortisol, haematocrit, haemoglobin, and liver glycogen in pirarucu. Thirty-six fish were handled by netting and subjected to air exposure for 75-min. Six fish were sampled before handling and at 0, 6, 24, 48, and 96h after handling. Fish cortisol, lactate and haematocrit rose after handling, returning to previous unstressed values on the following sampling (6h after handling). Glucose increased significantly after handling and that...

Autores: SCHWARTZ,Gustavo; HANAZAKI,Natalia; SILVA,Marivana B.; IZZO,Thiago J.; BEJAR,María E. P.; MESQUITA,Mariana R.; FERNANDES,G. Wilson.
Stressed plants are generally more attacked by galling insects. In this study we investigated the relationship between population abundance and species richness of galling insects on the tree Alchornea castaneaefolia A. JUSS. (Euphorbiaceae), submited to stress induced by the hemiparasite Psittacanthus sp. (Loranthaceae) in the Amazon, Brazil. Branches of A. castaneaefolia attacked by the hemiparasite were more heavily infested by galling insects than non-attacked branches. The field observations partially corroborate the hypothesis that there would be an optimal level of host-plant stress for galling insect establishment.

Physiological stress responses in the warm-water fish matrinxã (Brycon amazonicus ) subjected to a sudden cold shock
Provedor de dados: 36
Autores: Inoue,Luis Antonio Kioshi Aoki; Moraes,Gilberto; Iwama,George K.; Afonso,Luis Orlando Bertola.
The present work evaluated several aspects of the generalized stress response [endocrine (cortisol), metabolic (glucose), hematologic (hematocrit and hemoglobin) and cellular (HSP70)] in the Amazonian warm-water fish matrinxã (Brycon amazonicus ) subjected to an acute cold shock. This species farming has been done in South America, and growth and feed conversion rates have been interesting. However, in subtropical areas of Brazil, where the water temperature can rapidly change, high rates of matrinxã mortality have been associated with abrupt decrease in the water temperature. Thus, we subjected matrinxã to a sudden cold shock by transferring the fish directly to tanks in which the water temperature was 10ºC below the initial conditions (cold shock from...

Autores: Inoue,Luís Antônio Kioshi Aoki; Afonso,Luís Orlando B.; Iwama,George K.; Moraes,Gilberto.
Fish transport is one of the most stressful procedures in aquaculture facilities. The present work evaluated the stress response of matrinxã to transportation procedures, and the use of clove oil as an alternative to reduce the stress response to transport in matrinxã (Brycon cephalus). Clove oil solutions were tested in concentrations of 0, 1, 5 and 10 mg/L during matrinxã transportation in plastic bags, supplied with water and oxygen as the usual field procedures in Brazil. Clove oil reduced some of the physiological stress responses (plasma cortisol, glucose and ions) that we measured. The high energetic cost to matrinxã cope with the transport stress was clear by the decrease of liver glycogen after transport. Our results suggest that clove oil (5...

ABSTRACT The present work investigated the effects of aqueous extracts of eucalyptus ( Eucalyptus globulus) and elderberry ( Sambucus ebulus) leaves on β-carotene productivity in Dunaliella salina, a green microalga. Leaf extracts from eucalyptus have greater amounts of phenolics and flavonoids, as well as greater ferric reducing antioxidant potential than elderberry. The extracts of both species greatly inhibited growth of algal suspensions. However, chlorophyll and β-carotene concentration increased in cells treated with leaf extracts, and the highest values were detected in 1 % eucalyptus and 2 % elderberry extracts. Fresh weight, total sugar, and protein content significantly increased following exposure of cells to different doses of leaf extracts....

The Massaguaçu River estuary is an irregular estuary with sandbar breaching cycles that are irregular and happen several times each year. The species Ludwigia octovalvis is a perennial weed in several places around the world, but it is seasonal in the Massaguaçu River. In this survey we determined the relationship between the rain, estuary water level variation, and the spatial and temporal distribution of this species. In a laboratory we simulated the water level variation in water tanks in order to understand how this species responds to flooding. In the field, we determined the distribution of L. octovalvis in the higher pluviose season and in the lower pluviose season. This species is relatively common in the higher pluviose season and completely...

We tested the preference prediction of plant vigor hypothesis by examining the relationship between gall occurrence and leaf size. We also examined the effect of galls on leaf asymmetry, which is a measure of developmental instability. Gall occurrence did not increase with leaf size, thereby providing no support to the preference prediction. Galled leaves were significantly more asymmetric than ungalled leaves. Moreover, leaf asymmetry increased with both gall occurrence and gall size, indicating that galls boosted the stress levels in Ouratea polygyna.

Fish welfare: the state of science by scientometrical analysis
Provedor de dados: 3
Autores: Ghisi, Nédia de Castilhos; Oliveira, Elton Celton de.
 In 2014, Brazil produced 474.33 thousand tons of captive-bred fish. In addition, regulatory agencies of animal ethics and welfare have recently encouraged experiments to be done using simpler vertebrates, such as fish. The aim of this article was to perform a scientometric analysis of scientific production that deals with fish welfare, in an attempt to find trends and gaps in this line of research. Our analyses showed a growing concern about fish welfare, although several questions remained inadequately covered. The most studied species was the Atlantic salmon, with Norway having the most publications on this theme. There are controversies among scientists about fish capacity for suffering and enjoyment (sentience). As regards slaughter or euthanasia,...

Autores: Etim, Promise Joseph; Alonge, Akindele Folarin; Akpan, Godwin Edem.
Some mechanical properties of mucuna bean seed were studied at different moisture levels to provide relevant data for development of cracking machine for the seed. The frictional coefficient of the seed on five structural surfaces (plywood, aluminum, glass, steel, and wood) was determined using the incline plane method. The mechanical properties were determined using a Universal Testing Machine. The coefficients of friction of the seed on the respective structural surfaces were observed to have increased with increasing moisture levels. The force to crack the seed on its major axis decreased from 1595.1 to 244.9N as moisture level increased from 4.79 to 18.53% (dry basis), with a similar trend also observed on the minor axis. The deformation on both axes...

Provedor de dados: 111
Autores: Dehghan Hesar, Hadi; Kalantari, Davood.
This study presents a numerical investigation regarding the stress distribution on the new designed disc harrow using the ANSYS software. A conventional disc, notched disc, and a biomimetic design inspired by the claw of the leatherwing were analyzed in two conventional plowed and unplowed soils and three tillage depths (4, 7 and 10 cm). Stress analysis for all treatments showed that the highest stress was imposed at the disc-stem junction. Meanwhile the highest deformation occurred at the lowest and the most external part of the discs (land line). The results obtained in this study indicated that the maximum stress exerted from tilling soil to discs increases linearly with tillage depth in both plowed and unplowed soils. Given these results, the maximum...

Abstract Chronic stress exposure commonly increases adrenals weight and changes their morphology. This study aimed to compare four methods to delimitate the cortical and medullary layers of adrenals glands in Nelore bulls. Fresh adrenals did not present differentiation between layers. Then, frozen adrenals were distributed in plastics bags with fixative Bouin (G1), 96ºGL ethylic alcohol (G2), 10% formaldehyde (G3), or 2.5% glutaraldehyde (G4). After 12 hours of fixation, the G1 adrenal glands did not show the entire cortical layer marked by Bouin’s solution. For G2 and G3 there was a poor contrast, while for G4 there was a reasonable contrast. After 24 hours of fixation, G1 had an excellent contrast between layers, while G2 and G4 had a reasonable contrast...

Provedor de dados: 42
Autores: Mello,Pâmela Billig; Benetti,Fernando; Cammarota,Martín; Izquierdo,Iván.
Here we study the effect of acute and chronic physical exercise in a treadmill and of daily stress (because forced exercise involves a degree of stress) during 2 or 8 weeks on different types of memory in male Wistar rats. The memory tests employed were: habituation in an open field, object recognition and spatial learning in the Morris water maze. Daily foot-shock stress enhanced habituation learning after 2 but not after 8 weeks; it hindered both short- (STM) and long-term memory (LTM) of the recognition task at 2 weeks but only STM after 8 weeks and had no effect on spatial learning after either 2 or 8 weeks. Acute but not chronic exercise also enhanced habituation in the open field and hindered STM and LTM in the recognition task. Chronic exercise...

ABSTRACT Tambaqui,Colossoma macropomum is a fish of primary importance in Brazilian aquaculture and in the Amazon region in particular. The aim of this work is to analyze the combined effects of physical training and levels of dietary cassava (Manihot esculenta) on the hematological parameters, food intake, conversion efficiency, growth ratio and swimming performance of this fish. A diet for tambaqui consisting of 30% cassava caused decreases in weight gain and specific growth rate compared with the control group. Diets containing 15% or 45% cassava did not affect these indices and did not cause hematological changes in tambaqui juveniles, indicating that some amount of cassava can be used as an alternative energy source for this important aquaculture...

Provedor de dados: 45
Autores: Adamante,W.B.; Nuñer,A.P.O.; Barcellos,L.J.G.; Soso,A.B.; Finco,J.A.
The stress in dorado fingerlings (Salminus brasiliensis) caused by transportation at densities of 5, 10, and 15g/l after 4, 8, and 12h was evaluated by the concentration of tissue cortisol measured by ELISA. The conditions of transportation were simulated on an orbital table shaker with horizontal movements, inside 15 litres plastic bags filled with 4 litres of water and pure oxygen. Cortisol concentrations increased in all densities after 4h of transportation converging to a common concentration at the end of the tested times. Electrical conductivity of water increased with density and transportation time. The transportation caused stress on fish, but the increase on density and in times of transportation did not cause mortality to fingerlings. The...

The action of the "Stress Factor Ostrich (Arenales - Fauna and Flora)" was tested in the release of superoxide anion by cells in the peripheral blood of rhea (Rhea americana). Sixteen samples of 0.5mL of venous blood were collected through the jugular vein in the morning and placed in heparinized tubes. The leukocytes were separated into polymorphonuclear (PMN) and mononuclear (MN). The production of superoxide anion by phagocytes of peripheral blood was determined using the chromogen ferricytochrome C. There was a reduction of superoxide by MN cells in the presence of "Stress Factor Ostrich" indicating a positive influence of product against oxidative stress. Furthermore, future researches, such as the evaluation of other reactive oxygen intermediates and...

Fetal malformation in a marmoset (Callithrix jacchus): case report
Provedor de dados: 45
Autores: Ferraz,M.C.; Matos,A.V.R.; Prestes,N.C.; Ferreira,J.C.P.; Francelino,L.C.; Cunha,F.S.; Oba,E.
Callithrix jacchus is a neotropical primate adaptable in captivity. Colonies can be easily established in a short time and at low cost compared to other species of larger primates, which are normally used in laboratory. Because they are phylogenetically similar to humans in situations that induce anxiety, these small primates are increasingly being used in research involving the stress response. Wild animals in captivity are subjected to a series of stressful events that depending on the duration and intensity can modify the organic homeostasis. Observed in this study, serious problems occurred with the formation in fetal offspring of Callithrix jacchus kept in an environment with a high degree of stress.

Provedor de dados: 45
Autores: Bueno,A.R.; Rasby,R.; Clemens,E.T.
Seventy-five Angus x MARC II crossbred heifers were used to assess the effects of age at weaning on calf performance and blood constituents. Calves were weaned at 150, 210, or 270 days of age with comparisons made to their non-weaned counterparts. Changes in blood chemistry and hematology (cortisol, glucose, T3, total proteins, packed cell volume and the differential white blood cell count) were recorded on the day of weaning (day-0), and at 2, 7, 14, and 28 days post-weaning. Calves weaned at 210 days of age presented the highest plasma cortisol, glucose, and total protein concentrations during their early post-weaning period. Calves weaned at 150 days of age had significantly lower plasma T3 values. Packed cell volume and differential white blood cell...

Autores: Assis,V.D.L.; Carvalho,T.S.G.; Pereira,V.M.; Freitas,R.T.F.; Saad,C.E.P.; Costa,A.C.; Silva,A.A.A.
ABSTRACT This study evaluated the influence of physical environmental enrichment on the behavior of cockatiels (Nymphicus hollandicus). Eighteen birds, nine males and nine females, were monitored in environments enriched with wooden sticks and bead rings and in non-enriched environments, in a completely randomized design. Behavioral categories were grouped into locomotion, maintenance, rest, feed, undesirable activities, and interaction with environmental enrichment. Data were analyzed using descriptive analysis of behaviors to produce the ethogram and percentage comparison of frequency values for behavior analysis. Environmental enrichment positively influenced behavioral categories and some behavioral activities of birds.

On cognitive ecology and the environmental factors that promote Alzheimer disease: lessons from Octodon degus (Rodentia: Octodontidae)
Provedor de dados: 48
Autores: Rivera,Daniela S.; Inestrosa,Nibaldo C.; Bozinovic,Francisco.
Cognitive ecologist posits that the more efficiently an animal uses information from the biotic and abiotic environment, the more adaptive are its cognitive abilities. Nevertheless, this approach does not test for natural neurodegenerative processes under field or experimental conditions, which may recover animals information processing and decision making and may explain, mechanistically, maladaptive behaviors. Here, we call for integrative approaches to explain the relationship between ultimate and proximate mechanisms behind social behavior. We highlight the importance of using the endemic caviomorph rodent Octodon degus as a valuable natural model for mechanistic studies of social behavior and to explain how physical environments can shape social...

ABSTRACT The aim of this study was to evaluate the potential of calcium silicate to mitigate the effects of water deficiency in maize plants yield. A completely randomized factorial design, consisting of five combinations of calcium silicate (0, 25, 50, 75, and 100%) and five different soil moisture levels (30, 70, 100, 130, and 160%), was adopted. The following parameters were evaluated: soil matric potential, xylem water potential, silicon concentration, leaf dry weight, and dry mass production. Matric potential monitoring confirmed that the irrigation depths employed resulted in different environments for maize plant development during the experiment. Confirming the hypothesis of the study, at the lower irrigation depths, the maize production has...

Effect of temperature shock on soybean microspore embryogenesis
Provedor de dados: 52
Autores: Moraes,Ana Paula de; Bonadese-Zanettini,Maria Helena; Callegari-Jacques,Sídia Maria; Kaltchuk-Santos,Eliane.
In this study the effect of cold and heat shock on androgenetic induction in soybean anther culture was tested. Anthers of soybean were subjected to 4 and 33ºC, while the anthers used for control were maintained at 25ºC. Cytological analysis done during the 30 days of culture showed that frequencies of symmetrical binucleated and multicellular pollen grain did not differ among temperature treatments. Multicellular pollen grain could be formed by symmetrical division, as well as by assymetrical division. In relation to the embryo induction, the results of the treatments did not differ too. These results suggested that these treatments did not induce a sporophytic pathway in soybean.

Autores: Souza,Gustavo M.; Cardoso,Victor J. M.; Gonçalves,Antonio N.
Proline content and protein patterns changes in response to temperature shocks of both acclimated and non acclimated E. grandis shoots cultivated in vitro were investigated. Analysis of soluble proteins through SDS-PAGE and proline were carried out after 12h at 12ºC (cold acclimation) or 33ºC (heat acclimation), and immediately after temperature shocks at 41ºC and 0ºC. Analyses were also performed 24h after the temperature shocks (recovery period). Temperature treatment at 0ºC did not change soluble protein patterns both in acclimatized and non acclimatized plants, whereas cold temperature induced high proline levels, which kept relatively high after recovery period. Three novel, probably HSPs, proteins (90.5, 75 and 39 kDa) were observed in both...

Autores: Schwarz,Aline; Hosomi,Rosana Zoriki; Flório,Jorge Camilo; Bernardi,Maria Martha; Górniak,Silvana Lima; Spinosa,Helenice Souza.
The present study evaluated the central monoamine levels of male and female adult rat offspring exposed orally by gavage to 0.0, 0.7, 3.0 and 15.0 mg/kg I. carnea aqueous extract daily, from gestation day (GD) 5 to GD 21. Several alterations in the monoamine activity systems were observed. However, the major differences were noted between the 0.0 mg/kg and the no gavage control groups, showing that alterations showing that alterations were not due to the alterations to the aqueous extract. The control data showed that gavage and handling of dams were stressful enough to produce a significant decline in 3,4-dihydroxyphenylacetic acid (DOPAC) and an increase in vanilmandelic acid (VMA), indicating decreased dopamine (DA) and enhanced norepinephrine (NE)...

Autores: Sabioni,Rafael Estevan; Zanuzzo,Fábio Sabbadin; Cyrino,José Eurico Possebon.
Abstract Stress in intensive fish farming hamper immune function of fish and cause losses by disease outbreaks, a situation that can be minimized, but cannot be completely circumvented, by the use of immunomodulators. Addition of immunomodulators to aquafeeds has thus become a common practice. β-glucan (BG) is one of most studied and effective immunomodulators, aquaculture purposes included. Extracted from cell walls of bacteria, fungi and selected cereals, BG activity depends on the source and extraction methods. This study evaluated effects of two BG products (BG1 and BG2), extracted from Saccharomyces cerevisiae under varying extraction methods and with different immune activity, on the feeding of pacu Piaractus mesopotamicus juveniles.

This study was undertaken to determine the modulating effects of intramuscular administration of melatonin (MT)(1mg/ kg) and/or Tri-B (B 1 , B 6 and B 12 ) (20mg/kg) on body weight and some biochemical changes in rats induced by Epinephrine (Epi) injection. The data showed that MT and/or Tri-B treatment effectively improved the changes in malondialdehyde, lipid profile, blood sugar level and insulin. MT and/or Tri-B administration following Epi improved partially the decrease in body weight and liver glycogen levels. Tri B injection following Epi partialy improved all the tested parameters except malondialdehyde and blood sugar level that completely improved in stressed rats. It was evident that a combination of MT and vitamin B complex had protective...

Autores: Cortez,Célia Martins; Cruz,Frederico Alan de Oliveira; Silva,Dilson.
A new application for the nuclear imaging techniques is the study of organic responses to stress. Neuroimaging techniques allow the assessment of brain activation changes in association with the metabolic responses to stress. In this paper, a review of general effects of the stress on organic activity is made, emphasizing important advances introduced by studies using PET and fMRI. The importance of the hypothalamus-pituitary-adrenal axis to onset the adequate psychical and organic responses to sustain the homeostasis during the stress is discussed, as well as the possibility of traumatic stressing experiences have negative effects on the brain.

ABSTRACT Stress can inhibit gonadal activity via Hypothalamus-Pituitary-Gonad (HPG) axis activity suppression. In the present study, effects of intermittent feeding (IF) on gonadal function under stress in male and female mice were evaluated. Twenty eight male and twenty eight female mice's were divided into four groups. The control group received adequate food and water without stress. The second group received four days of electric shock without food deprivation. The third group was deprived of food two hours/day for a week, and the fourth group was deprived of food (2 hours/day for seven consecutive days) and then electric foot shock stress was applied to them for four days. Blood samples were collected from all animals for plasma testosterone, estrogen...

Effect of salt on the growth and metabolism of Glycine max
Provedor de dados: 52
Autores: Queiroz,Helena Müller; Sodek,Ladaslav; Haddad,Claudia Regina Baptista.
Soybean plants cultivated with 50, 100 and 200 mM of NaCl, revealed that root growth was less affected by salinity than shoots. Salinity led to a reduction in leaf area and an increase in water content of the roots. These factors could contribute to the adaptation of the plant, improving its hydration. Although nitrate and free amino acid levels were reduced by salt treatment in roots, protein content of leaves was not altered. Salinity led to alterations in xylem amino acid composition, with increases in Ser, Ala, Gaba and Pro and a decrease in Asn. Similar changes were seen for Asn and Ser in roots together with a much stronger increase in Gaba. It is suggested that the decline in Asn reflects its conversion to Ala and Gaba (via Glu) in the roots while...

Gastric ulcer accounts for one of the most important causes of abdominal discomfort in young horses. With the aim of studying the prevalence of lesions (ulcers and/or erosions) and their relationship to factors such as stress, age and sex, sixty quarter horse foals without signs of gastric disease underwent gastroscopy. Foals were divided into four age groups of 15 animals as follows: 1 to 30 days, 31 to 60 days, 61 to 90 days and 91 to 120 days. The prevalence of gastric lesions was 43.3%. Foals aged 61 to ninety days were the most affected (nine of 15). There were no significant differences between ages. Squamous epithelial exfoliation was observed in nine foals (60%) less than thirty days, in six (40%) between 31 to sixty days and only in two foals...

Social condition affects hormone secretion and exploratory behavior in rats
Provedor de dados: 56
Autores: Genaro,G.; Schmidek,W.R.; Franci,C.R.
Studies of behavior, endocrinology and physiology have described experiments in which animals housed in groups or in isolation were normally tested individually. The isolation of the animal from its group for testing is perhaps the most common situation used today in experimental procedures, i.e., there is no consideration of the acute stress which occurs when the animal is submitted to a situation different from that it is normally accustomed to, i.e., group living. In the present study, we used 90 male 120-day-old rats (Rattus norvegicus) divided into 5 groups of 18 animals, which were housed 3 per cage, in a total of 6 cages. The animals were tested individually or with their groups for exploratory behavior. Hormones were determined by radioimmunoassay...

Routine post-weaning handling of rats prevents isolation rearing-induced deficit in prepulse inhibition
Provedor de dados: 56
Autores: Rosa,M.L.N.M.; Silva,R.C.B.; Moura-de-Carvalho,F.T.; Brandão,M.L.; Guimarães,F.S.; Del Bel,E.A.
Rats reared under isolation conditions from weaning present a number of behavioral changes compared to animals reared under social conditions (group housing). These changes include deficits in prepulse inhibition (PPI) of the startle reflex to a loud sound. PPI refers to the reduction of the magnitude of the startle reflex when a relatively weak stimulus (the prepulse) precedes by an appropriate time interval the intense startle-elicing stimulus (the pulse). PPI is useful for studying sensorimotor integration. The present study evaluated the effect of handling on the impairment of PPI induced by isolation-rearing. Male Wistar rats (N = 11-15/group) were housed in groups (5 per cage and handled three times a week) or isolated (housed individually) since...

The influence of stress on fear memory processes
Provedor de dados: 56
Autores: Martijena,I.D.; Molina,V.A.
It is well recognized that stressful experiences promote robust emotional memories, which are well remembered. The amygdaloid complex, principally the basolateral complex (BLA), plays a pivotal role in fear memory and in the modulation of stress-induced emotional responses. A large number of reports have revealed that GABAergic interneurons provide a powerful inhibitory control of the activity of projecting glutamatergic neurons in the BLA. Indeed, a reduced GABAergic control in the BLA is essential for the stress-induced influence on the emergence of associative fear memory and on the generation of long-term potentiation (LTP) in BLA neurons. The extracellular signal-regulated kinase (ERK) subfamily of the mitogen-activated protein kinase (MAPK) signaling...

Neonatal handling induces anovulatory estrous cycles in rats
Provedor de dados: 56
Autores: Gomes,C.M.; Frantz,P.J.; Sanvitto,G.L.; Anselmo-Franci,J.A.; Lucion,A.B.
Since previous work has shown that stimulation early in life decreases sexual receptiveness as measured by the female lordosis quotient, we suggested that neonatal handling could affect the function of the hypothalamus-pituitary-gonadal axis. The effects of neonatal handling on the estrous cycle and ovulation were analyzed in adult rats. Two groups of animals were studied: intact (no manipulation, N = 10) and handled (N = 11). Pups were either handled daily for 1 min during the first 10 days of life or left undisturbed. At the age of 90 days, a vaginal smear was collected daily at 9:00 a.m. and analyzed for 29 days; at 9:00 a.m. on the day of estrus, animals were anesthetized with thiopental (40 mg/kg, ip), the ovaries were removed and the oviduct was...

Neuroethologic differences in sleep deprivation induced by the single- and multiple-platform methods
Provedor de dados: 56
Autores: Medeiros,R.; Lenneberg-Hoshino,C.; Hoshino,K.; Tufik,S.
It has been proposed that the multiple-platform method (MP) for desynchronized sleep (DS) deprivation eliminates the stress induced by social isolation and by the restriction of locomotion in the single-platform (SP) method. MP, however, induces a higher increase in plasma corticosterone and ACTH levels than SP. Since deprivation is of heuristic value to identify the functional role of this state of sleep, the objective of the present study was to determine the behavioral differences exhibited by rats during sleep deprivation induced by these two methods. All behavioral patterns exhibited by a group of 7 albino male Wistar rats submitted to 4 days of sleep deprivation by the MP method (15 platforms, spaced 150 mm apart) and by 7 other rats submitted to...

Effects of simultaneous exposure to stress and nicotine on nicotine-induced locomotor activation in adolescent and adult rats
Provedor de dados: 56
Autores: Zago,A.; Leão,R.M.; Carneiro-de-Oliveira,P.E.; Marin,M.T.; Cruz,F.C.; Planeta,C.S.
Preclinical studies have shown that repeated stress experiences can result in an increase in the locomotor response to the subsequent administration of drugs of abuse, a phenomenon that has been termed behavioral cross-sensitization. Behavioral sensitization reflects neuroadaptive processes associated with drug addiction and drug-induced psychosis. Although cross-sensitization between stress- and drug-induced locomotor activity has been clearly demonstrated in adult rats, few studies have evaluated this phenomenon in adolescent rats. In the present study, we determined if the simultaneous exposure to stress and nicotine was capable of inducing behavioral sensitization to nicotine in adolescent and adult rats. To this end, adolescent (postnatal day (P)...

Salivary cortisol and α-amylase: subclinical indicators of stress as cardiometabolic risk
Provedor de dados: 56
Autores: Cozma,S.; Dima-Cozma,L.C.; Ghiciuc,C.M.; Pasquali,V.; Saponaro,A.; Patacchioli,F.R.
Currently, the potential for cardiovascular (CV) stress-induced risk is primarily based on the theoretical (obvious) side effects of stress on the CV system. Salivary cortisol and α-amylase, produced respectively by the hypothalamus-pituitary-adrenal (HPA) axis and the sympathetic-adrenomedullary (SAM) system during stress response, are still not included in the routine evaluation of CV risk and require additional and definitive validation. Therefore, this article overviews studies published between 2010 and 2015, in which salivary cortisol and α-amylase were measured as stress biomarkers to examine their associations with CV/CMR (cardiometabolic risk) clinical and subclinical indicators. A comprehensive search of PubMed, Web of Science and Scopus...

Aversive stimulation during the stress-hyporesponsive period does not affect the number of corticotroph cells in neonatal male rats
Provedor de dados: 56
Autores: Aguiar,C.E.; Cadore,L.P.; Padoin,M.J.; Barbosa-Coutinho,L.M.; Lucion,A.B.
Immunohistochemistry was used to evaluate the effects of neonatal handling and aversive stimulation during the first 10 days of life on the number of corticotrophs in the anterior lobe of the pituitary of 11-day-old male Wistar rats. Since adult rats handled during infancy respond with reduced corticosterone secretion in response to stressors and with less behavior inhibition in novel environments, we assumed that neonatal stimulation could affect pituitary morphology during this critical period of cell differentiation. Three groups of animals were studied: intact (no manipulation, N = 5), handled (N = 5) and stimulated (submitted to 3 different aversive stimuli, N = 5). The percentage of ACTH-immunoreactive cells in the anterior lobe of the pituitary...

Changes in the behavioral and immunological parameters of the mollusk Biomphalaria tenagophila induced by disruption of the circadian cycle as a consequence of continuous illumination
Provedor de dados: 56
Autores: Waissel,I.; Mineo,J.R.; Natal,C.L.
In the present investigation we studied some behavioral and immunological parameters of adult gastropod mollusk, Biomphalaria tenagophila, which have been reproducing for several generations under laboratory conditions. One group of gastropods was kept on a 14-h light/10-h dark cycle, corresponding to a regular circadian cycle, and another group was exposed to continuous light for 48 h. Animals were studied along (behavioral groups) or immediately after (immunological groups) 48 h of regular circadian cycle or continuous light conditions. Stopping/floating, dragging and sliding were the behavioral aspects considered (N = 20 for regular cycle; N = 20 for continuous illumination) and number of hemocytes/µl hemolymph was the immunological parameter studied (N...

Sleep deprivation reduces the lymphocyte count in a non-obese mouse model of type 1 diabetes mellitus
Provedor de dados: 56
Autores: Ruiz,F.S.; Andersen,M.L.; Zager,A.; Martins,R.C.S.; Tufik,S.
The objective of the present study was to determine whether sleep deprivation (SD) would promote changes in lymphocyte numbers in a type 1 diabetes model (non-obese diabetic, NOD, mouse strain) and to determine whether SD would affect female and male NOD compared to Swiss mice. The number of lymphocytes in peripheral blood after 24 and 96 h of SD (by multiple platform method) or equivalent period of time in home-cage controls was examined prior to the onset of diabetes. SD for 96 h significantly reduced lymphocytes in male Swiss mice compared to control (8.6 ± 2.1 vs 4.1 ± 0.7 10³/µL; P &lt; 0.02). In male NOD animals, 24- and 96-h SD caused a significant decrease of lymphocytes compared to control (4.4 ± 0.3 vs 1.6 ± 0.5; P &lt; 0.001 and 4.4 ± 0.3 vs 0.9...

Estrous cycle and stress: influence of progesterone on the female brain
Provedor de dados: 56
Autores: Lovick,T.A.
The female brain operates in a constantly changing chemical milieu caused by cyclical changes in gonadal hormones during the estrous cycle (menstrual cycle in women). Such hormones are highly lipophilic and pass readily from the plasma to the brain where they can influence neuronal function. It is becoming clear that the rapid reduction in peripheral circulating progesterone, which occurs during the late diestrous phase of the cycle, can trigger a withdrawal-like response, in which changes in GABA A receptor expression render hyper-responsive certain brain areas involved in processing responses to stressful stimuli. The periaqueductal gray matter (PAG) is recognised as an important region for integrating anxiety/defence responses. Withdrawal from...

Effects on prolactin secretion and binding to dopaminergic receptors in sleep-deprived lupus-prone mice
Provedor de dados: 56
Autores: Palma,B.D.; Hipolide,D.C.; Tufik,S.
Sleep disturbances have far-reaching effects on the neuroendocrine and immune systems and may be linked to disease manifestation. Sleep deprivation can accelerate the onset of lupus in NZB/NZWF1 mice, an animal model of severe systemic lupus erythematosus. High prolactin (PRL) concentrations are involved in the pathogenesis of systemic lupus erythematosus in human beings, as well as in NZB/NZWF1 mice. We hypothesized that PRL could be involved in the earlier onset of the disease in sleep-deprived NZB/NZWF1 mice. We also investigated its binding to dopaminergic receptors, since PRL secretion is mainly controlled by dopamine. Female NZB/NZWF1 mice aged 9 weeks were deprived of sleep using the multiple platform method. Blood samples were taken for the...

Exposure to stress induces a cluster of physiological and behavioral changes in an effort to maintain the homeostasis of the organism. Long-term exposure to stress, however, has detrimental effects on several cell functions such as the impairment of antioxidant defenses leading to oxidative damage. Oxidative stress is a central feature of many diseases. The lungs are particularly susceptible to lesions by free radicals and pulmonary antioxidant defenses are extensively distributed and include both enzymatic and non-enzymatic systems. The aim of the present study was to determine lipid peroxidation and total radical-trapping potential (TRAP) changes in lungs of rats submitted to different models of chronic stress. Adult male Wistar rats weighing 180-230 g...

Restraint-induced hypoactivity in an elevated plus-maze
Provedor de dados: 56
Autores: Padovan,C.M.; Guimarães,F.S.
Rodents submitted to restraint stress show decreased activity in an elevated plus-maze (EPM) 24 h later. The objective of the present study was to determine if a certain amount of time is needed after stress for the development of these changes. We also wanted to verify if behavioral tolerance of repeated daily restraint would be detectable in this model. Male Wistar rats were restrained for 2 h and tested in the EPM 1, 2, 24 or 48 h later. Another group of animals was immobilized daily for 2 h for 7 days, being tested in the EPM 24 h after the last restraint period. Restraint induced a significant decrease in the percent of entries and time spent in the open arms, as well as a decrease in the number of enclosed arm entries. The significant effect in the...

Endometriosis is a progressive estrogen-dependent disease affecting women during their reproductive years. The objective of the present study was to investigate whether endometriosis is associated with stress parameters. We determined cortisol and prolactin levels in serum, peritoneal and follicular fluid from infertile women with endometriosis and fertile women without the disease. The extent of the disease was staged according to the revised American Fertility Society classification (1997). Serum and peritoneal fluid were collected from 49 women aged 19 to 39 years undergoing laparoscopy. Eighteen women had stage I-II endometriosis and 10 had stage III-IV. Controls were 21 women undergoing laparoscopy for tubal sterilization. Follicular fluid was...

Effect of repeated stress on novelty-induced antinociception in rats
Provedor de dados: 56
Autores: Torres,I.L.S.; Vasconcellos,A.P.; Silveira Cucco,S.N.; Dalmaz,C.
There is extensive evidence that acute stress induces an analgesic response in rats. On the other hand, repeatedly stressed animals may present the opposite effect, i.e., hyperalgesia. Furthermore, exposure to novelty is known to induce antinociception. The effects of repeated restraint stress on nociception after exposure to novelty, as measured by the tail-flick latency (TFL), were studied in adult male rats. The animals were stressed by restraint 1 h daily, 5 days a week for 40 days. The control group was not submitted to restraint. Nociception was assessed with a tail-flick apparatus. After being familiarized with the TFL apparatus, each group was subdivided into two other groups, i.e., with or without novelty. Animals were subjected to the TFL...

Recent studies have employed tympanic thermometry to assess lateralization of cognitive and emotional functions in primates. However, no studies using this technique have investigated the possibility of hemispheric specialization in New World monkeys. Therefore, the aim of the present study was to investigate tympanic membrane (TM) temperature asymmetries and their possible correlation with stress responses in marmosets (Callithrix penicillata). Infrared TM thermometry was completed bilaterally in 24 animals (14 males and 10 females) during a stressful situation of capture and restraint. There were no significant differences between gender. A significant negative correlation was observed between TM temperature of the right ear and the number of captures (r...

Autores: Guimarães,C.M.; Pinge,M.C.M.; Yamamura,Y.; Mello,L.E.A.M.
Stress is a well-known entity and may be defined as a threat to the homeostasis of a being. In the present study, we evaluated the effects of acupuncture on the physiological responses induced by restraint stress. Acupuncture is an ancient therapeutic technique which is used in the treatment and prevention of diseases. Its proposed mechanisms of action are based on the principle of homeostasis. Adult male Wistar EPM-1 rats were divided into four groups: group I (N = 12), unrestrained rats with cannulas previously implanted into their femoral arteries for blood pressure and heart rate measurements; group II (N = 12), rats that were also cannulated and were submitted to 60-min immobilization; group III (N = 12), same as group II but with acupuncture needles...

Concomitant stress potentiates the preference for, and consumption of, ethanol induced by chronic pre-exposure to ethanol
Provedor de dados: 56
Autores: Morais-Silva,G.; Fernandes-Santos,J.; Moreira-Silva,D.; Marin,M.T.
Ethanol abuse is linked to several acute and chronic injuries that can lead to health problems. Ethanol addiction is one of the most severe diseases linked to the abuse of this drug. Symptoms of ethanol addiction include compulsive substance intake and withdrawal syndrome. Stress exposure has an important role in addictive behavior for many drugs of abuse (including ethanol), but the consequences of stress and ethanol in the organism when these factors are concomitant results in a complex interaction. We investigated the effects of concomitant, chronic administration of ethanol and stress exposure on the withdrawal and consumption of, as well as the preference for, ethanol in mice. Male Swiss mice (30–35 g, 8-10 per group) were exposed to an ethanol liquid...

Autores: Barreto,R.E.; Volpato,G.L.
Plasma cortisol and glucose levels were measured in 36 adult Nile tilapia males, Oreochromis niloticus (standard length, mean ± SD, 14.38 ± 1.31 cm), subjected to electroshock and social stressors. Pre-stressor levels were determined 5 days after the adjustment of the fish to the experimental aquaria (1 fish/aquarium). Five days later, the effects of stressors on both cortisol and glucose levels were assessed. The following stressors were imposed for 60 min: pairing with a larger resident animal (social stressor), or a gentle electroshock (AC, 20 V, 15 mA, 100 Hz for 1 min every 4 min). Each stressor was tested in two independent groups, one in which stress was quantified immediately after the end of the 60-min stressor imposition (T60) and the other in...

Isolation and characterization of Caulobacter mutants impaired in adaptation to stationary phase
Provedor de dados: 58
Autores: Italiani,Valéria C. S.; Marques,Marilis V.
The entry into stationary phase causes a change in the pattern of gene expression of bacteria, when the cells must express a whole set of genes involved mainly with resistance to starvation and to environmental stresses. As an attempt to identify genes important for the survival of Caulobacter crescentus in stationary phase, we have screened a library of 5,000 clones generated by random transposon mutagenesis for mutants that showed reduced viability after prolonged growth. Four clones were selected, which displayed either lower viability or a longer time of recovery from stationary phase. The genes disrupted were identified, and the gene products were found to be mainly involved with amino acid metabolism (glutamate N-acetyltransferase,...

Probiotics are viable defined microorganisms (bacteria or yeasts) that exert a beneficial effect on the health of the host when ingested in adequate amounts. Screening for such biotherapeutic agents is commonly performed by in vitro assays simulating gastrointestinal environment to determine the ability to survive in the digestive tract. In the present study, the possibility of extrapolation of data obtained in in vitro assays to in vivo conditions was studied using five Saccharomyces cerevisiae strains isolated from Brazilian Atlantic rain forest. Trehalose contents and survival after exposure to a combination of physiological stresses generally found in the gastrointestinal tract of humans were determined for the five yeasts and compared to the behavior...

Phosphorus and nitrogen interaction: loss of QC identity in response to P or N limitation is antecipated in pdr23 mutant
Provedor de dados: 61
Autores: Costa,Cibele T.; Strieder,Mércio L.; Abel,Stephen; Delatorre,Carla A.
Changes in root architecture are an important adaptive strategy used by plants in response to limited nutrient availability to increase the odds of acquiring them. The quiescent center (QC) plays an important role by altering the meristem activity causing differentiation and therefore, inducing a determinate growth program. The arabidopsis mutant pdr23 presents primary short root in the presence of nitrate and is inefficient in the use of nucleic acids as a source of phosphorus. In this study the effect of the pdr23 mutation on the QC maintenance under low phosphorus (P) and/or nitrogen is evaluated. QC identity is maintained in wild-type in the absence of nitrate and/or phosphate if nucleic acids can be used as an alternative source of these nutrients,...

ABSTRACT: Trees in the production systems can effectively reduce hot weather-induced stress in the Brazilian Midwest. High temperatures cause changes in animals daily routine, and trees into pastures can promote benefits. The aim of this research was to evaluate the behavior of dairy heifers in silvopastoral systems in the state of Mato Grosso, Brazil. A herd of 24 crossbreed heifers (3/4 and 7/8 Holstein/Zebu), 350kg average weight, was evaluated over three seasons. Piatã grass was managed under three shade levels: full-sun, moderate-shade, and intensive-shade provided by 10 to 12m high Eucalyptus trees. Behavior data were collected every 15 minutes from 8:30h to 16h. Shade availability significantly impacted heifer behavior, mainly affecting grazing...

Autores: Abreu,Janessa Sampaio de; Sanabria-Ochoa,Ana Isabel; Gonçalves,Flávio Daolio; Urbinati,Elisabeth Criscuolo.
Optimum loading density for the transport of matrinxã juveniles was investigated in a closed system with plastic bags. Transport was conducted for 4 h with fish (23.5± 0.4g and 11.6 (0.08cm) starved for 24h at loading densities of 83g L-1 (D1), 125g L-1 (D2), 168g L-1 (D3) and 206g L-1 (D4). Fish were sampled before transport (BT), after transport (AT) and 24h AT. The water quality was monitored before capturing fish in depuration tanks, after transport in plastic bags and in recovery tanks. Water oxygen decreased to values below 4mg L-1 in D2, D3 and D4, temperature was around 32°C, pH 6.5-6.78, total ammonia 1.09-1.7mg L-1, un-ionized ammonia 3.58-9.33x10³mg L-1 and alkalinity 134-165mg CaCO3 L-1. Blood cortisol and glucose concentrations increased in...

Agronomic performance of male-sterile and fertile maize genotypes at two plant populations
Provedor de dados: 65
Autores: Sangoi,Luís; Salvador,Ricardo.
This experiment was conducted in 1994 at Ames, Iowa, US to test whether cytoplasmic male-sterility can be used to decrease barrenness and to increase grain yield of maize at two plant populations. Four genotypes were tested: a hybrid (NK 6330) and an inbred, wifh sterile and fertile counterparts. Each genotype owas evaluated at plant populations equivalent to 25,000 and 75,000 pl. ha-1. Hybrids produced higher grain yield than inbreds at both plant populations. Gram yield was higher at 75,000 than at 25,000 pl. ha-1. No difference in gram yield, number of ears per plant, number of grains per ear, tassel length, and tassel number of branches was found between sterile and fertile counterparts of the inbred and hybrid, regardiess of plant population. Fertile...

The objective of this study was to investigate if piglets that suck anterior teats differ from the others in the litter in birth weight, if they have higher growth rate during lactation, and if this affects behaviour and post-weaning weight gain, when piglets change to a solid diet. For this, the teat order of 24 litters was determined during suckling. Piglets were weaned on the 28thday of age, and 24 groups were formed, composed of one piglet that sucked on the first two pairs of teats (AT) and three piglets that sucked on the other teats (OT). Even though weight at birth did not vary according to teat order, weight gain at weaning differed between the groups (AT: 6.64, S.E. 0.20kg, OT: 5.73, S.E. 0.13kg; P&lt;0.001). After weaning, AT piglets spent more...

ABSTRACT: This study aimed to examine the action of the essential oil of Lippia alba (EOLA) in the stress response for transport of Nile tilapia Oreochromis niloticus . The fish were transported into three treatments (in triplicate): control, 10 and 20 µL L-1 EOLA, with loading density of 15 fish/plastic bags for 8h. Plasma glucose levels were significantly decreased in fish exposed to 20µL L-1 EOLA in comparison with the control group and fish exposed to 10µL L-1 EOLA, but the plasma cortisol, lactate and paraoxonase levels were similar. Un-ionized ammonia and ventilatory rate demonstrated a significant reduction in the treatments with the use of EOLA. In conclusion the use of 20µL L-1 EOLA is indicated for Nile tilapia transport.

Textural behavior of gels formed by rice starch and whey protein isolate: Concentration and crosshead velocities
Provedor de dados: 64
Autores: Silva,Thiago Novaes; Costa,Angélica Ribeiro da; Garcia-Rojas,Edwin Elard.
ABSTRACT Fabricated food gels involving the use of hydrocolloids are gaining polpularity as confectionery/convenience foods. Starch is commonly combined with a hydrocolloid (protein our polyssacharides), particularly in the food industry, since native starches generally do not have ideal properties for the preparation of food products. Therefore the texture studies of starch-protein mixtures could provide a new approach in producing starch-based food products, being thus acritical attribute that needs to be carefully adjusted to the consumer liking. This work investigated the texture and rheological properties of mixed gels of different concentrations of rice starch (15%, 17.5%, and 20%) and whey protein isolate (0%, 3%, and 6%) with different crosshead...
