Poucos estudos apresentam interações entre a fisiologia das plantas e sua posterior composição química, quando cultivadas em diferentes arranjos. Esta pesquisa buscou compreender a relação entre o espaço de cultivo da soja e sua influência sobre a qualidade da semente. Foram estudadas duas cultivares de soja (Tec 7849 Ipro e Monsoy 6972 Ipro) em quatro arranjos espaciais distintos (50,0 x 7,1; 40,0 x 8,9; 30,0 x 11,9 e 18,9 x 18,9 ou 16,2 x 16,2 cm, respectivamente). Durante os estádios fenológicos V4 e R2, foram analisadas trocas gasosas e na colheita, foram constituídos 2 grupos, um de sementes frescas e outro de sementes envelhecidas, para ambos os grupos se analisaram: teste de germinação, vigor, índice de velocidade de germinação, massa fresca das...

Reserve substances and storage of Cyathea delgadii Sternb. spores
Provedor de dados: 88
Autores: SIMABUKURO,ELIANA A.; CARVALHO,MARIA ANGELA M. DE; FELIPPE,G. M.
The spores used were collected from a population of trees of Cyathea delgadii Sternb. growing in a gallery forest at the Reserva Biológica e Estação Experimental de Moji Guaçu, São Paulo state, Brazil (22°18’S and 47°11’W). The germination of spores of Cyathea delgadii decreases with time when kept in closed bottles under storage at 4°C in darkness. Germination is still very high after storage for one year. Spores stored for three years do not germinate. The results also show a decrease in soluble proteins and an increase in starch after several months storage.

Oil and fat in broiler nutrition
Provedor de dados: 89
Autores: Baião,NC; Lara,LJC.
The terms "fat" and "oil" refer to triglycerides of several profiles of fatty acids. Fatty acids that are not bound to other organic components as glycerol are the so-called free fatty acids. Lipids constitute the main energetic source for animals and they have the highest caloric value among all the nutrients. Linoleic acid is the only fatty acid whose dietetic requirement has been demonstrated. Besides supplying energy, the addition of fat to animal diets improves the absorption of fat-soluble vitamins, decreases pulverulence, increases diet palatability, and the efficiency of utilization of the consumed energy. Furthermore, it reduces the rate of food passage through the gastrointestinal tract, which allows a better absorption of all nutrients present...

Females of Tapinotaspoides, a genus in the oil-collecting bee tribe Tapinotaspidini, collect secretions from non-floral trichomes (Hymenoptera, Apidae)
Provedor de dados: 92
Autores: Melo,Gabriel A. R.; Gaglianone,Maria Cristina.
Harvesting of secretions from non-floral trichomes by females of Tapinotaspoides serraticornis is reported for the first time. The females exhibit a type of mopping behavior using the fringes of long, wavy setae along the posterior margins of their metasomal sterna. Our observations indicated a wide range of host plants used as sources for these secretions, including Waltheria (Sterculiaceae), Tibouchina (Melastomataceae), Sida (Malvaceae), Jacquemontia (Convolvulaceae), and unidentified species of Commelinaceae and Cyperaceae.

Provedor de dados: 92
Autores: Camargo,Roberto S.; Lopes,Juliane F. S.; Forti,Luiz C.; Somera,Alexandre F.; Bacci Jr,Mauricio.
Energy substrate used by workers of leaf-cutting ants during nest excavation. In this study we aimed to ascertain whether leaf-cutting ant workers lose body reserves (fat or sugars) as a function of nest excavation. For each treatment, we isolated 10 workers of Atta sexdens into two experimental groups, Control (C- without excavation) and Soil (S- with excavation), which were kept for different time intervals (0, 24, 48 or 72 hours), totaling 700 tested workers. We then determined the concentration of soluble carbohydrates and total lipid content in them. The total carbohydrates were determined colorimetrically, based on the reaction between carbohydrates and sulfuric acid-phenol. For determination of lipids, the insects were immersed in organic solvent...

Pectin degradation in ripening and wounded fruits
Provedor de dados: 93
Autores: HUBER,DONALD J.; KARAKURT,YASAR; JEONG,JIWON.
Pectin depolymerization during fruit ripening has been shown to be largely due to pectinolytic enzymes, including polygalacturonases (E.C. 3.2.1.15) and pectinmethylesterases (E.C. 3.2.1.11). Studies have shown that these enzymes are not the primary determinants of softening, although participation in texture changes during the late stages of ripening seems evident. Pectin depolymerization differs significantly between various fruit types, notably avocado and tomato, even though levels of extractable PG activity in these fruits are similar. Collective evidence indicates that the activities of some cell wall enzymes are restricted in vivo, with maximum hydrolytic potential expressed only in response to tissue disruption or wounding. In contrast, other...

Seed reserve composition and mobilization during germination and initial seedling development of Euphorbia heterophylla
Provedor de dados: 93
Autores: SUDA,CECILIA N.K.; GIORGINI,JARBAS F.
Seed composition and reserve mobilization were investigated in wild poinsettia (Euphorbia heterophylla L.). Lipids, around 60% of seed dry mass, are the major reserve. Proteins, including albumins (49%), salt insoluble globulins (30%), salt-soluble globulins (21%) and prolamins (0.3%), comprise about a quarter of seed dry mass. Soluble sugars comprise about 3.6% of seed dry mass, sucrose being the predominant sugar. Starch was not detected in the endosperm of E. heterophylla. Lipid depletion starts after initial imbibition, and is completed between 72 and 96 hours. Protein fractions exhibit different degradation patterns, salt-soluble globulins being continuously degraded after the start of imbibition whereas salt insoluble fractions are degraded between...

Changes in hormonal balance as key to reserve degradation after dormancy overcoming in Annona macroprophyllata and Annona purpurea seeds
Provedor de dados: 94
Autores: Ferreira,Gisela; De-la-Cruz-Chacón,Ivan; González-Esquinca,Alma Rosa.
Abstract  Studies on the effect of the applying of phytoregulators to overcome seed dormancy have been carried out in Annonaceae species, thus the endogenous relationship between abscisic acid and gibberellins after the application of phytoregulators needs to be known in these species. Considering the importance of hormonal balance in dormancy mechanisms, the aim of this research was to elucidate how endogenous ABA and GA concentrations change after the application of phytoregulators in seeds and how these changes affect reserve degradation during germination of Annona macroprophyllata and A. purpurea seeds. Seeds were submitted to three conditions: - no soaking, soaking-in-water and soaking-in-GA4+7+benzyladenine. ABA, GA, lipids, proteins, and total...

Provedor de dados: 95
Autores: Corte,Viviana Borges; Borges,Eduardo Euclydes de Lima e; Gonçalves,José Francisco de Carvalho; Silva,Mirian Sousa.
The decay of seeds is irreversible and at best can only be delayed by applying techniques that reduce the velocity of the metabolic reactions involved. There is little information on the biochemistry of tropical forest tree seeds related to their storability. It was investigated the influence of the composition of lipids and soluble sugars of two storage compartments, the cotyledons and the embryonic axis, of Melanoxylon brauna Schot. (Leguminosae- Caesalpinioideae), a hardwood known as black brauna, seeds stored at 20 ºC for 0, 3, 6, 9 and 12 months (natural ageing) and for 0, 24, 48, 72 and 96 hours at 40 ºC (accelerated ageing). The levels of fatty acids and monosaccharides varied differentially in each of the embryo storage compartments. Changes in...

Temporal dynamics of milk composition of the precocial caviomorph Octodon degus (Rodentia: Octodontidae)
Provedor de dados: 97
Autores: VELOSO,CLAUDIO; KENAGY,G.J.
During lactation, both the nutritional and energetic requirements of suckling change gradually. These changes normally are accompanied by modifications in chemical composition of the milk. We investigated the temporal course of milk composition during lactation in a precocial caviomorph rodent, the "degu" (Octodon degus) under laboratory condition. Female degus were kept in laboratory during gestation and lactation and fed with commercial food pellets. Milk was collected at three stages of lactation: early (days 5-8, n = 12), middle (days 15-21, n = 7) and late (days 26-40, n = 6), and analyzed for protein, carbohydrates, lipids, ash, total solids and energy. On average, carbohydrates decreased from 3.1 ± 0.3 % (early) to 1.1 ± 0.3 % (late) during...

Critical Review: Essential fatty acids on shrimp feeding
Provedor de dados: 22
Autores: Lima, Rodrigo Barbosa; Figueiredo-Lima, Denise Fontana.
Four types of poly unsaturated fatty acids (PUFA) are essential for all shrimp species, linoleic (LOA, 18:2n-6), alfa-linolenic (ALA, 18:3n-3), eicosapentaenoic (EPA, 20:5n-3) and docosahexaenoic (DHA, 22:6n-3) acids. Moreover, the arachidonic acid (ARA, 20:4n-6), even when present, seems to be, in crustaceans, not so important or yet dispensable. It is relevant knowing that cholesterol as much as PUFA are not well absorbed when not followed by a substantial amount of lecithin, reaching 5% of the ration. The sum of PUFA reaches around 3% of the diet, even varying according to the species, stage and ration type. For Penaeus monodon, a complex mathematic model was formulated in order to describe the relationships between the requirements of the cited PUFA....

Fatty acid composition of commercially important fish from Brazil
Provedor de dados: 63
Autores: Gutierrez,L.E.; Silva,R.C.M. da.
Total fat and fatty acid composition of seven fresh-water and nine marine fish commercially important in Brazil were determined. Palmitic acid was the predominant saturated fatty acid in both freshwater and marine fish. In the fat from freshwater fish the total C-16 fatty acids were higher than in marine fish. Oleic acid was the most abundant monounsaturated fatty acid and it was found in higher levels in freshwater fish. The data revealed that most freshwater fish from Brazil examined were a poor source of eicosapentaenoic (20:5) and docosahexaenoic (22:6) acids. Of the marine fish analysed, only sardine and manjuba could be recommended as a good sources of n-3 fatty acids.

Lipid extract and fatty acid composition of cane molasses and yeasts (Saccharomyces cerevisiae M-300-A and Saccharomyces uvarum IZ-1904) grown in molasses medium were determined. In molasses, linoleic acid was found in higher levels (around 42%) and was followed by palmitic, oleic and linolenic acids. The lipid extract varied from 1.02 to 3.13 gkg-1. In yeasts, the level of lipid extract varied from 16.65 to 31.12 g.kg-1 (dry matter basis) depending on the molasses type and yeast species. Both yeasts were able to incorporate fatty acids from molasses' and therefore linoleic and palmitic acids were the major fatty acids found in them.

Depending on the greenhouse gas emission scenarios, air [CO2] could rise to between 421 and 936 ?L L-1, accompanied by a global surface warming between 0.3 and 4.8?C along the 2nd half of the present century. It is well known that supra-optimal air temperatures may cause significant disturbances in metabolism and plant growth, since biochemical reactions are accelerated, the chemical bonds are weakened and the lipid matrix of membranes becomes more fluid. Thylakoid membranes are particularly sensitive to supra-optimal temperatures, so that impairments at the photochemical steps of photosynthesis are among the first indicators of sensitivity to heat stress. Plants acclimate to thermal stress by means of a myriad of mechanisms, such as, increased expression...

Lipids, including the diterpenes cafestol and kahweol, are key compounds that contribute to the quality of coffee beverages. We determined total lipid content and cafestol and kahweol concentrations in green beans and genotyped 107 Coffea arabica accessions, including wild genotypes from the historical FAO collection from Ethiopia. A genome-wide association study was performed to identify genomic regions associated with lipid, cafestol and kahweol contents and cafestol/kahweol ratio. Using the diploid Coffea canephora genome as a reference, we identified 6,696 SNPs. Population structure analyses suggested the presence of two to three groups (K = 2 and K = 3) corresponding to the east and west sides of the Great Rift Valley and an additional group formed by...

Abstract: The effects of nitrogen (N) and/or phosphorus (P) starvation on the biochemical composition of native microalgae Chlorella spp. polyculture obtained from the phycoremediation of swine wastewaters were investigated. Microalgae-specific growth rate of 1.2 day(-1) was achieved (30.3 mg L(-1) day(-1)). PO4 (-2) and NH3 were completely removed from swine digestate effluent after 3 and 11 days, respectively. Microalgae harvested immediately after nutrient removal showed high protein (56-59 %) and carbohydrate (25-34 %) but low lipid (1.8-3 %) contents. Depletion of N or P alone stimulated carbohydrate production at the expenses of proteins. Significant lipid accumulation from 3 %&amp;#8201;±&amp;#8201;0.5 to 16.3 %&amp;#8201;±&amp;#8201;0.8 was reached...

Autores: Bertholdi,Angelo Albano da Silva; Costa,Vladimir Eliodoro; Rodrigues,Angélica Lino; Almeida,Luiz Fernando Rolim de.
ABSTRACT Water deficit is most frequent in forest physiognomies subjected to climate change. As a consequence, several tree species alter tissue water potential, gas exchange and production of carbon compounds to overcome damage caused by water deficiency. The working hypothesis, that a reduction in gas exchange by plants experiencing water deficit will affect the composition of carbon compounds in soluble sugars, lipids and vegetative structures, was tested on Copaifera langsdorffii. Stomatal conductance, leaf water potential, and CO2 assimilation rate declined after a period of water deficit. After rehydration, leaf water potential and leaf gas exchange did not recover completely. Water deficit resulted in 13C enrichment in leaves, soluble sugars and...

How to construct and use a simple device to prevent the formation of precipitates when using Sudan Black B for histology
Provedor de dados: 39
Autores: Oliveira,João Marcelo Santos de.
The present work aims to demonstrate the stages of fabrication and use of a simple device to avoid the formation or fixation of precipitates from Sudan Black B solution on tissues. The device consists of four coverslip fragments attached to a histology slide, which serve as points of support for the histological slide under analysis. To work properly, the histology slide with the sections should be placed with the sections facing downwards the device. A small space between the device and the histology slide is thereby created by the height of the coverslip fragments. When Sudan Black B is applied, the solution is maintained within the edges of the device and evaporation is minimized by the small space, thereby reducing the consequent formation of...

Simultaneous dehydration and infiltration with (2-hydroxyethyl)-methacrylate (HEMA) for lipid preservation in plant tissues
Provedor de dados: 39
Autores: Oliveira,João Marcelo Santos de.
Although this study aims to develop an improved method for the preservation of reserve lipids in plant tissues for different uses in plant anatomy, it mostly aims to develop an improved method for the identification of lipid reserves where synthesis or storage occurs. The proposed procedures entail only the utilization of (2-hydroxyethyl)-methacrylate (HEMA) as a dehydration agent. One of the procedures is based on the gradual exchange of aqueous HEMA solutions with increasing concentrations. In another procedure, dehydration and infiltration are induced by the presence of silica gel around a modified microcentrifuge tube containing the aqueous HEMA solution with the plant tissues, thus allowing efficient lipid preservation. Both procedures resulted in...

Nutritious tissue in petals of Annonaceae and its function in pollination by scarab beetles
Provedor de dados: 39
Autores: Gottsberger,Gerhard; Webber,Antonio Carlos.
ABSTRACT The feeding of pollinating dynastid-scarab beetles on nutritious tissue of Annonaceae flowers results in macroscopically visible gnawing marks on petals. In the present paper, we present and discuss examples of such gnawing marks on Annonaceae from the Cerrado and the Amazon Forest in Brazil. The localization of gnawing marks on the petals and the histochemistry of the nutritious tissues are emphasized. In some species, nutritious tissue is apparently distributed among all petals, while in other species it is more or less diffusely localized. There are also cases in which nutritious tissue occurs only on clearly localized regions of the inner petals. Petals of selected Amazon species were stained, and studied by light and scanning electron...

Sarcocornia ambigua is a perennial glasswort, native of South America and a potential new seed-oil crop and forage for direct irrigation with salt water. Small seeds develop inside fertile segments of its cylindrical leafless shoots and, at the harvest, seeds are typically mixed with remnant cellulose material difficult to separate. This work evaluated different extraction methods and the composition of total esterified fatty acids in a meal of ground fertile shoots of S. ambigua, seeking for an alternative primary matter and larger yield of total lipids. The highest lipid yield was obtained with a chloroform:methanol mixture (2:1)(v/v) (5.2% of dry weight). The most abundant polyunsaturated fatty acids in the meal were linoleic acid (C18:2; 21.4%) and...

Autores: Zink,Klaus-Gerhard; Furtado,André L. S.; Casper,Peter; Schwark,Lorenz.
Freshwater lagoons comprise important coastal ecosystems and natural buffers between urbanized land areas and open ocean in the Rio de Janeiro State, Brazil. Studies of sediment and water chemistry, zooplankton and bacterial communities to assess the extent of anthropogenic disturbance are available. Here we contribute with an organic-geochemical approach supplemented by some microbiological aspects to complete the characterization of these lagoonal ecosystems. Bulk organic matter and extractable lipids (aliphatic hydrocarbons, alcohols and fatty acids, sterols) were investigated from two locations per lagoon: at the seaward site and landward ends - and at two depth intervals (0-3 and 3-6 cm) per site. Urbanized Imboacica Lagoon received increased...

Cereus jamacaru, a Cactaceae found throughout northeast Brazil, is widely used as cattle food and as an ornamental and medicinal plant. However, there has been little information about the physiological and biochemical aspects involved in its germination. The aim of this study was to investigate its reserve mobilization during germination and early seedling growth. For this, C. jamacaru seeds were germinated in a growth chamber and collected at 0, 2, 4, 5, 6, 8 and 12 days after imbibition for morphological and biochemical analyses. Dry seeds had wrinkled seed coats and large, curved embryos. Lipids were the most abundant reserve, comprising approximately 55% and 65% of the dry mass for cotyledons and the hypocotylradicle axis, respectively. Soluble sugars...

ABSTRACT Piau porcine blastocysts were submitted to MALDI-TOF to identify the main phospholipids (PL). After that, in vivo blastocysts (D6) were vitrified (n=52), non-vitrified were used as control (n=42). After warming, blastocysts were in vitro cultured to assess re-expansion and hatching at 24 and 48 hours. Finally, at 48 hours, hatched blastocysts were submitted to RT-qPCR searching for BCL2A1, BAK, BAX and CASP3 genes. For MALDI-TOF, the ion intensity was expressed in arbitrary units. Blastocyst development was compared by Qui-square (P&lt; 0.05). Among the most representative PL was the phosphatidylcholine [PC (32:0) + H]+; [PC (34:1) + H]+ and [PC (36:4) + H]+. Beyond the PL, MALDI revealed some triglycerides (TG), including PPL (50:2) + Na+, PPO...

The aim of the present study was to examine the effect of a diet rich in synthetic PEtn on the metabolism macrophages of tumor-bearing mice. The results demonstrated that PEtn increased the animals' survival time. In addition, the treated animals released smaller amounts of hydrogen peroxide (H2O2) and nitric oxide (NO) than the non-treated animals, particularly after day 14. From the results it could be concluded that H2O2 and NO were important in the modulation of neoplastic growth, and pointed to a promising role of PEtn in the control of human neoplasms.

Studies have been conducted on microalga Spirulina platensis (Arthrospira platensis) due to its therapeutic potential in several areas, including the capacity for preventing and decreasing the damages caused by hyperlipidemia and the antioxidant activity. The aim of the study was to evaluate the effect of microalga Spirulina platensis on hippocampus lipoperoxidation and lipid profile in rats with induced hypercholesterolemia during 60 days. The measurement of hippocampus lipoperoxidation did not demonstrate significant difference (p&gt;0.05) when Spirulina platensis was added to hypercholesterolemic diet. The evaluation of lipid profile showed that the administration of the microalga in therapeutic and preventive ways led to a significant protective effect...

Hyperlipidemia has been frequently recorded as a side effect of treating HIV patients with protease inhibitors (PI). This study was initiated to analyze the modifications on blood lipids in HIV-patients receiving PI and the safety and efficacy of the treatment with fenofibrate. Total (TC) and HDL-cholesterol, triglycerides (TG), and CD4+ T-cell counts were measured in 30 HAART-naive patients (Group I) before and after PI introduction. In a second phase of the study, the effects of fenofibrate on lipids, CPK, CD4+, and viral load were determined in 13 patients (Group II) with elevated TC or TG. In Group I, 60% of the patients showed TC or TG elevations. Average increments of 31% and 146% in TC and TG respectively (p&lt;0.0006 and p&lt;0.0001) were observed....

Inhibition of rat microsomal lipid peroxidation by the oral administration of D002
Provedor de dados: 56
Autores: Menéndez,R.; Amor,A.M.; González,R.M.; Jiménez,S.; Más,R.
The effect of D002, a defined mixture of higher primary alcohols purified from bee wax, on in vivo and in vitro lipid peroxidation was studied. The extent of lipid peroxidation was measured on the basis of the levels of thiobarbituric acid reactive substances (TBARS). When D002 (5-100 mg/kg body weight) was administered orally to rats for two weeks, a partial inhibition of the in vitro enzymatic and non-enzymatic lipid peroxidation was observed in liver and brain microsomes. Maximal protection (46%) occurred at a dose of 25 mg/kg. D002 behaved differently depending on both the presence of NADPH and the integrity of liver microsomes, which suggests that under conditions where microsomal metabolism was favored the protective effect of D002 was increased....

Effect of FSH and insulin on lipogenesis in cultures of Sertoli cells from immature rats
Provedor de dados: 56
Follicle-stimulating hormone (FSH) and insulin regulate glycide metabolism in Sertoli cells, thus stimulating lactate production. These stimulatory effects of FSH and insulin do not require protein synthesis, suggesting a modulation of enzyme activity and/or regulation of glucose transport. The present investigation was performed to characterize the hormonal control of lipid metabolism in Sertoli cells. The data indicate that FSH and insulin have a regulatory effect on lipid metabolism in Sertoli cells. After 8 h of preincubation with insulin (5 µg/ml), the activity of the enzyme ATP-citrate lyase in cultured Sertoli cells was increased from 0.19 to 0.34 nmol NAD+ formed µg protein-1 min-1. FSH (100 ng/ml) had no effect on this enzyme. Glycerol phosphate...

Monounsaturated fats and immune function
Provedor de dados: 56
Autores: Yaqoob,P.
Animal studies suggest that olive oil is capable of modulating functions of cells of the immune system in a manner similar to, albeit weaker than, fish oils. There is some evidence that the effects of olive oil on immune function in animal studies are due to oleic acid rather than to trace elements or antioxidants. Importantly, several studies have demonstrated effects of oleic acid-containing diets on in vivo immune responses. In contrast, consumption of a monounsaturated fatty acid (MUFA)-rich diet by humans does not appear to bring about a general suppression of immune cell functions. The effects of this diet in humans are limited to decreasing aspects of adhesion of peripheral blood mononuclear cells, although there are trends towards decreases in...

Pequi is the fruit of Caryocar brasiliense and its oil has a high concentration of monounsaturated and saturated fatty acids, which are anti- and pro-atherogenic agents, respectively, and of carotenoids, which give it antioxidant properties. Our objective was to study the effect of the intake of a cholesterol-rich diet supplemented with pequi oil, compared to the same diet containing soybean oil, on atherosclerosis development, and oxidative stress in atherosclerosis-susceptible LDL receptor-deficient mice (LDLr-/-, C57BL/6-background). Female mice were fed a cholesterol-rich diet containing 7% soybean oil (Soybean group, N = 12) or 7% pequi oil (Pequi group, N = 12) for 6 weeks. The Pequi group presented a more atherogenic lipid profile and more advanced...

Proteoliposomes as matrix vesicles' biomimetics to study the initiation of skeletal mineralization
Provedor de dados: 56
Autores: Simão,A.M.S.; Yadav,M.C.; Ciancaglini,P.; Millán,J.L.
During the process of endochondral bone formation, chondrocytes and osteoblasts mineralize their extracellular matrix by promoting the formation of hydroxyapatite (HA) seed crystals in the sheltered interior of membrane-limited matrix vesicles (MVs). Ion transporters control the availability of phosphate and calcium needed for HA deposition. The lipidic microenvironment in which MV-associated enzymes and transporters function plays a crucial physiological role and must be taken into account when attempting to elucidate their interplay during the initiation of biomineralization. In this short mini-review, we discuss the potential use of proteoliposome systems as chondrocyte- and osteoblast-derived MVs biomimetics, as a means of reconstituting a phospholipid...

Autores: Valente Gamba,C.; Zeraib Caraviello,A.; Matsushita,A.; Alves,G.M.; Nunes da Silva,L.; Nascimento Gomes,G.; Zaladek Gil,F.
Normal aging is accompanied by renal functional and morphological deterioration and dietetic manipulation has been used to delay this age-related decline. We examined the effects of chronic administration of diets containing 5% lipid-enriched diet (LD, w/w) on renal function of rats at different ages. Three types of LD were tested: canola oil, fish oil and butter. Mean systemic tail-cuff blood pressure and glycemia remained within the normal range whatever the age and the diet of the animals. Proteinuria began to rise from the 8th month in the groups ingesting LD, while in the control group it increased significantly (above 10 mg/24 h) only after the 10th month. With age, a significant and progressive decline in glomerular filtration rate (GFR) and renal...

Cardiovascular disease is the primary cause of death in Brazil. Recent studies have shown that low birth weight and preterm birth are linked to a higher prevalence of cardiovascular disease. The aim of the present study was to compare the levels of lipids and apolipoproteins and atherogenic indexes between term and near-term newborn infants. A sample of umbilical cord blood was obtained from 135 newborns (66 males) divided into two groups: 25 near-term neonates (35-36.6 weeks of gestational age) and 110 term neonates (37-42 weeks of gestational age). The total cholesterol concentrations were higher in the near-term neonates than in the term group (94.04 ± 8.02 vs 70.42 ± 1.63 mg/dl, P &lt; 0.01), due to an increase in the LDL-cholesterol fraction in the...

Lipid oxidation in meat: mechanisms and protective factors – a review
Provedor de dados: 116
Autores: AMARAL,Ana Beatriz; SILVA,Marcondes Viana da; LANNES,Suzana Caetano da Silva.
Abstract  Lipid oxidation in meats is a process whereby polyunsaturated fatty acid react with reactive oxygen species leading to a series of secondary reactions which in turn lead to degradation of lipids and development of oxidative rancidity. This process is one of the major factors responsible for the gradual reduction of sensory and nutritional quality of meats, thus affecting consumer acceptance. Therefore, the control and minimization of lipid oxidation in meat and meat products is of great interest to the food industry. In view of this, some technologies have been developed, such as vacuum packaging, modified atmosphere, and use of antioxidants. The aim is understanding the lipid oxidation mechanisms responsible for sensory and nutritional quality...

Effect of temperature and nitrogen concentration on biomass composition of Heterochlorella luteoviridis
Provedor de dados: 116
Autores: MENEGOL,Tania; DIPRAT,Andressa Bacalau; RODRIGUES,Eliseu; RECH,Rosane.
Abstract The interest in microalga as a food supplement has grown due their high contents of carotenoids, polyunsaturated fatty acids and proteins. This study evaluated the effect of different temperatures (22, 27 or 32 °C) and sodium nitrate concentrations (12, 24, 36, 48 or 60 mg L-1 of N-NO3) in culture medium on Heterochlorella luteoviridis biomass production and composition. The highest biomass concentration (3.35 g L-1) was observed at the highest N-NO3 concentration. The N-NO3 concentration positively affected protein, carbohydrate and carotenoids contents of biomass. On the other hand, cells cultured at the lowest N-NO3 concentration showed a slight increment in lipid content. The major carotenoid was lutein (30.7 ± 1.4% of total carotenoids), and...

Autores: Cruz,Christian Albert Carvalho da; Santos-Cruz,Cristiane Leal dos; Castillo,Carmen Josefina Contreras; Souza,Alexilda Oliveira de; Silva,Lílian Borges da; Brito,Priscila Nunes.
The edible portion of the shoulder of 12 castrated and 12 non-castrated Santa Inês lambs slaughtered at different ages (84, 168, 210, 252 days) were used. The shoulders were chemically analyzed to determine the quantity of total lipids, cholesterol, and fatty acids composition. Castrated and non-castrated lambs gained body weight (p = 0.0393, p = 0.0017) and half carcass weight (p = 0.0240, p = 0.0017), respectively. The shoulder weight was increased in the carcasses of non-castrated lambs (p = 0.0110). The edible portion of the shoulder of castrated lambs presented higher total lipids (16.09 g.100 g-1). The cholesterol content was influenced by castration (p = 0.0001) reducing with age. Castrated animals presented higher content of C18:1 T11, CLA, and...

The goal of this study was to evaluate the effects of seasonal variations on energy metabolism in different tissues of the freshwater crayfish Parastacus brasiliensis (von Martens, 1869). Crayfish were collected monthly from January 2001 to January 2003 in São Francisco de Paula, Rio Grande do Sul, Brazil, in a stream and in a culture tank. Haemolymph samples were collected from each crayfish in the field with a syringe, by puncturing the membrane at the base of the chelipeds. Hepatopancreas, gills, and abdominal muscle were removed for determination of free glucose, glycogen, total lipids, and triglycerides. The haemolymph samples were used for determination of glucose, total proteins, total lipids, and triglycerides. Statistical analysis revealed...

Role of Gag and lipids during HIV-1 assembly in CD4(+) T cells and macrophages
Provedor de dados: 5
Autores: Mariani, Charlotte; Desdouits, Marion; Favard, Cyril; Benaroch, Philippe; Muriaux, Delphine M.
HIV-1 is an RNA enveloped virus that preferentially infects CD4(+) T lymphocytes and also macrophages. In CD4(+) T cells, HIV-1 mainly buds from the host cell plasma membrane. The viral Gag polyprotein targets the plasma membrane and is the orchestrator of the HIV assembly as its expression is sufficient to promote the formation of virus-like particles carrying a lipidic envelope derived from the host cell membrane. Certain lipids are enriched in the viral membrane and are thought to play a key role in the assembly process and the envelop composition. A large body of work performed on infected CD4(+) T cells has provided important knowledge about the assembly process and the membrane virus lipid composition. While HIV assembly and budding in macrophages is...

Combined Effects of Nitrogen Concentration and Seasonal Changes on the Production of Lipids in Nannochloropsis oculata
Provedor de dados: 5
Autores: Olofsson, Martin; Lamela, Teresa; Nilsson, Emmelie; Berge, Jean-pascal; Del Pino, Victoria; Uronen, Pauliina; Legrand, Catherine.
Instead of sole nutrient starvation to boost algal lipid production, we addressed nutrient limitation at two different seasons (autumn and spring) during outdoor cultivation in flat panel photobioreactors. Lipid accumulation, biomass and lipid productivity and changes in fatty acid composition of Nannochloropsis oculata were investigated under nitrogen (N) limitation (nitrate:phosphate N:P 5, N:P 2.5 molar ratio). N. oculata was able to maintain a high biomass productivity under N-limitation compared to N-sufficiency (N:P 20) at both seasons, which in spring resulted in nearly double lipid productivity under N-limited conditions (0.21 g L−1 day−1) compared to N-sufficiency (0.11 g L−1 day−1). Saturated and monounsaturated fatty acids increased from 76% to...

As condition is a key variable in population dynamics (especially for survival, growth and reproduction), the use of well-defined and accurate fish condition indices is capital. In particular, condition indices (morphometric, bioenergetic and biochemical) have never been compared and validated for the European anchovy Engraulis encrasicolus, the European pilchard Sardina pilchardus and the European sprat Sprattus sprattus. The accuracy of two indirect methods, the morphometric relative condition index Kn and the bioenergetics index determined with the Distell Fish Fatmeter was investigated by comparing with a direct measure of relative lipid content carried out with a thin layer chromatography-flame ionization detector.

Autores: Olofsson, Martin; Lamela, Teresa; Nilsson, Emmelie; Berge, Jean-pascal; Del Pino, Victoria; Uronen, Pauliina; Legrand, Catherine.
While focus in oil-producing microalgae is normally on nutrient deficiency, we addressed the seasonal variations of lipid content and composition in large-scale cultivation. Lipid content, fatty acid profiles and mono- di- and triglycerides (MAGs, DAGs, and TAGs) were analyzed during May 2007-May 2009 in Nannochloropsis oculata grown outdoors in closed vertical flat panels photobioreactors. Total lipids (TL) ranged from 11% of dry weight (DW) in winter to 30% of DW in autumn. 50% of the variation in TL could be explained by light and temperature. As the highest lipid content was recorded during autumn indicating an optimal, non-linear, response to light and temperature we hypothesize that enhanced thylakoid stacking under reduced light conditions resulted...

Relations entre le contenu lipidique des ovocytes de Pecten maximus (Mollusque, bivalve) et les performances des larves en élevage
Provedor de dados: 5
Autores: Le Pennec, Marcel; Gueguen,.
The lipid content of spawned oocytes of Pecten maximus was studied by image analysis of semi -thin histological sections and a lipid index was defined. The female gametes were obtained by thermic stimulations of mature adults scallops from different populations after out of season conditioning or sampled in situ during the spawning season. After fertilization, the larval development was followed. The results reveal a large variability in lipid content of normal oocytes. The lipid content can be regarded as homogeneous inside a spawning but the heterogeneity is greater for wild scallops than for conditioned ones. A strong relationship appears between the lipid index and the hatching success, and the number of abnormal larvae after two days rearing. But no...

Use of lipids to study the trophic ecology of deep-sea xenophyophores
Provedor de dados: 5
Autores: Laureillard, J; Mejanelle, L; Sibuet, Myriam.
Xenophyophores, widespread giant deep-sea protists, dominate the megafaunal organisms visible on the seafloor in some areas. Owing to the extreme fragility of their tests (external part), little is known about them, and their diet is largely a matter of speculation. The extensive accumulation of fecal pellets (stercomes) within their tests attests to the degree to which xenophyophores feed on particulate matter. During the EUMELI 2 cruise, xenophyophores were recovered intact at the surface of box-cores from an abyssal mesotrophic site in the northeastern Atlantic. They were identified as Syringammina corbicula. In our study, we compare the lipid composition of xenophyophores collected at the top of cores with sediment from the same mesotrophic environment...

Haptophytes are a diverse monophyletic group with a worldwide distribution, known to be significantly involved in global climate regulation in their role as a carbon sink. Because nitrogen is a major limiting macronutrient for phytoplankton in oceans and for cultures of microalgae, understanding the involvement of nitrogen availability in haptophyte carbon partitioning is of global and biotechnological importance. Here, we made an ecophysiological study coupled with comprehensive large scale proteomic analysis to examine differences of behavior in reaction to nitrogen availability changes between a wild type strain of Tisochrysis lutea (WTc1) and a mutant strain (2Xc1) known to accumulate more storage lipids. Strains were grown in chemostats and studied...

Effect of nutrition on Crassostrea gigas larval development and the evolution of physiological indices Part B: Effects of temporary food deprivation
Provedor de dados: 5
Autores: Ben Kheder, Rym; Quere, Claudie; Moal, Jeanne; Robert, Rene.
In the natural environment bivalve larvae are exposed to variable conditions and can therefore face periods of food shortage. To understand the resistance of early life stages of Pacific oyster (Crassostrea gigas), larvae were experimentally starved for 4 days at different periods of their development, and the resulting variations in their lipid reserves then analysed using image analysis and biochemical techniques. Faced with a temporary lack of food, the larvae halted their growth in size and weight and started to live off their lipid reserves; this effect was highly marked when the period of food deprivation was at the beginning of larval rearing, but was less marked when food deprivation was after day 14. The larvae conserved their developmental...

Fatty acids from lipids of marine organisms: Molecular biodiversity, roles as biomarkers, biologically active compounds, and economical aspects
Provedor de dados: 5
Autores: Berge, Jean-pascal; Barnathan, Gilles.
Because of their characteristic living environments, marine organisms produce a variety of lipids. Fatty acids constitute the essential part of triglycerides and wax esters, which are the major components of fats and oils. Nevertheless, phospholipids and glycolipids have considerable importance and will be taken into account, especially the latter compounds that excite increasing interest regarding their promising biological activities. Thus, in addition to the major polyunsaturated fatty acids (PUFA) such as eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids, a great number of various fatty acids occur in marine organisms, e.g. saturated, mono- and diunsaturated, branched, halogenated, hydroxylated, methoxylated, non-methylene-interrupted. Various...

Muscle bioenergetics of two emblematic Mediterranean fish species: Sardina pilchardus and Sparus aurata
Provedor de dados: 5
Autores: Teulier, Loïc; Thoral, Elisa; Queiros, Quentin; Mckenzie, David; Roussel, Damien; Dutto, Gilbert; Gasset, Eric; Bourjea, Jerome; Saraux, Claire.
We investigated links between swimming behavior and muscle bioenergetics in two emblematic Mediterranean fish species that have very different ecologies and activity levels. European sardines Sardina pilchardus are pelagic, they swim aerobically, school constantly and have high muscle fat content. Gilthead seabream Sparus aurata are bentho-pelagic, they show discontinuous spontaneous swimming patterns and store less fat in their muscle. Estimating the proportion of red and white muscle phenotypes, sardine exhibited a larger proportion of red muscle (~10% of the body mass) compared to gilthead seabream (~5% of the body mass). We firstly studied red and white muscle fiber bioenergetics, using high-resolution respirometers, showing a 4-fold higher oxidation...

Comment protéger les acides gras polyinsaturés à longues chaînes oméga 3 (AGPI -- LC ω3) vis-à-vis de l’oxydation ?
Provedor de dados: 5
Autores: Genot, Claude; Eymard, Sylvie; Viau, Michèle.
Increase the consumption of long-chain omega 3 polyunsaturated fatty acids (LC ω3 PUFA) is highly recommended for their health benefits. However, these fatty acids are very prone to oxidation, which can impair sensory, nutritional and functional properties of foods. In this paper the various ways that increase LC ω3 PUFA stability during processing and storage of food products are reviewed. To efficiently protect LC ω3 PUFA during processing and storage of foods, a combined strategy, taking into account both the matrix and the process should be undertaken. First the quality of the raw materials should be rigorously controlled by, for example, increasing contents of in situ antioxidants and decreasing length of storage. Then, during processing and storage...

Provedor de dados: 5
Autores: Da Costa, F.; Petton, Bruno; Mingant, Christian; Bougaran, Gael; Rouxel, Catherine; Quere, Claudie; Wikfors, G. H.; Soudant, P.; Robert, Rene.
Effects of a remarkably high overall lipid Tisochrysis lutea strain (T+) upon gross biochemical composition, fatty acid (FA), sterol and lipid class composition of Crassostrea gigas larvae were evaluated and compared with a normal strain of Tisochrysis lutea (T) and the diatom Chaetoceros neogracile (Cg). In a first experiment, the influence of different single diets (T, T+ and Cg) and a bispecific diet (TCg) was studied, whereas, effects of monospecific diets (T and T+) and bispecific diets (TCg and T+Cg) were evaluated in a second experiment. The strain T+ was very rich in triglycerides (TAG: 93–95% of total neutral lipids), saturated FA (45%), monounsaturated FA (31–33%) and total fatty acids (4.0–4.7 pg cell−1). Larval oyster survival and growth rate...

A brief review of nutritional studies for Penaeus monodon
Provedor de dados: 5
Autores: Liao, I; Liu, F.
In order to develop effective formulated for Penaeus monodon , sufficient information is needed on its nutritional requirements. Unfortunately, research on this area has been very limited. This paper outlines the results of such research. Since data on the nutritional requirements of P. japonicus are relatively well established, some of these data are also reviewed in this paper and are used as a basis for assessing the nutritional requirements of P. monodon . Protein, lipid, carbohydrate, mineral and vitamin requirements are evaluated from the parameters of growth survival and feed efficiency. Studies on the effects of enzymes and the development of microparticulate diet for larvae are also summarized.

Autores: Long, Marc; Tallec, Kevin; Soudant, Philippe; Le Grand, Fabienne; Donval, Anne; Lambert, Christophe; Sarthou, Geraldine; Jolley, Dianne F.; Hegaret, Helene.
Allelochemical interactions are likely to be a contributing factor explaining the success of large blooms of the harmful marine dinoflagellate Alexandrium, however, the physiological mechanisms of allelochemical interactions remain poorly described. Here we investigated the sub-lethal effects (on an hourly scale) of a filtrate containing allelochemicals from Alexandrium minutum on the physiology of the common diatom Chaetoceros muelleri. The filtrate induced deleterious effects to the diatom physiology within only 30 min of exposure. Esterase activity and photosynthesis were drastically inhibited, with up to 34% of the population being metabolically inactive and up to 30% reduction in photosystem II quantum yield when exposed to the filtrate. In addition,...

Autores: Pethybridge, H.; Daley, R.; Virtue, P.; Butler, E. C. V.; Cossa, Daniel; Nichols, P. D.
Total mercury (Hg) concentrations and lipid composition data, including fatty acid profiles, for 61 midtrophic species (fish, cephalopods, crustaceans) collected from continental slope waters off south-east Australia were examined. Overall, Hg concentrations were greatest in fish (0.01-0.30 mu g g(-1) ww) (with highest content found in barracouta (Thyrsites atun) and whiptails (Coelorinchus fasciatus)), compared with cephalopods (0.01 and 0.17 mu g g(-1) ww) and crustaceans (&lt;0.04 mu g g(-1) ww). Lipid composition varied between species and within habitat (mesopelagic, bathypelagic and benthic). Mean total lipid content ranged from 0.5 to 13.2% ww, and in most species was dominated by triacylglycerols and phospholipids. In fish and squid, fatty acids...

Sedimentation pathways in the Indian sector of the Southern Ocean during a production regime dominated by regeneration
Provedor de dados: 5
Autores: Cailliau, C; Belviso, S; Goutx, M; Bedo, A; Park, Y; Charriaud, E.
During summer 1994, the production regime at 2 sites located in the Indian sector of the Southern Ocean, one in the Permanent Open Ocean Zone (POOZ) at 52 degrees S, and a second in the Seasonal Ice Zone (SIZ) at 63 degrees S, was dominated by regeneration (0.3 &lt; f-ratio &lt; 0.4). Two time series, each of about 4 d, were performed over pre-determined time intervals of 4 h using a free-floating sediment trap set at 200 m at the 2 sites. Hourly variations of C, N, chlorophyll a (chl a) and its degradation products, taxon-specific pigments, lipid classes and dimethylsulfoniopropionate (DMSP) were measured simultaneously. Measurements in the water column were done during the sediment trap drifting. Fucoxanthin, a typical diatom pigment, was the major...

Draft genomes and phenotypic characterization of Tisochrysis lutea strains. Toward the production of domesticated strains with high added value
Provedor de dados: 5
Autores: Carrier, Gregory; Baroukh, Caroline; Rouxel, Catherine; Duboscq-bidot, Laetitia; Schreiber, Nathalie; Bougaran, Gael.
Tisochrysis lutea is a microalga species currently used in aquaculture as a feed for shellfish, oysters and shrimps. It also has many other potential industrial applications, such as the production of neutral lipids for biofuels or the production of ω-3 fatty acids for nutraceuticals (human food complements). To efficiently exploit the potential of this microalga, however, higher lipid productivities are needed. To this end, improvement programs need to be developed and optimized. The diversity of strains available in microalgae has not yet been exploited in such improvement programs. In this study, the intra-strain diversity was observed and exploited to increase neutral lipid productivity. New clonal strains with higher neutral lipid productivity were...

Fatty acid composition in deep hydrothermal vent symbiotic bivalves.
Provedor de dados: 5
Autores: Ben-mlih, F; Marty, Jc; Fiala-médioni, A.
Fatty acids in deep hydrothermal vent bivalves have been analyzed. Their composition is completely different from that of a littoral mussel collected in the Mediterranean sea. The distribution of fatty acids in the littoral mussel is characterized by a predominance of polyunsaturated fatty acids (20:5n-3, 22:6n-3) reflecting the planktonic origin of the food. Vent bivalve fatty acid distribution is dominated by an abundance of the monounsaturated acids (double bond in the n-7 position) 16:1n-7, 18:1n-7, and 20:1n-7 which are clearly of bacterial origin and give an indication of the symbiotic bacterial activity in the bivalves. Differences between the fatty acid composition of the bivalves from two hydrothermal sites (13 degrees N and Galapagos) and...

Allocation du carbone et métabolisme azoté chez l'haptophyte Tisochrysis lutea
Provedor de dados: 5
Autores: Garnier, Matthieu.
The aim of this thesis is to improve knowledge on mechanisms involved in the response to nitrogen limitation and in lipid accumulation in the microalgae haptophyte Tisochrysis lutea. The wild type strain and a lipid accumulating mutant strain were grown under different nitrogen limitation and starvation and analyzed by functional genomics. Four genes of high-affinity nitrate/nitrite transporter (Nrt2) were identified and characterized to reveal the mechanisms involved in mineral absorption in this species. Transcriptomes of both strains were sequenced and proteins affected by nitrogen starvation and differentially expressed between the two strains were identified. We so identified the functions regulated by nitrogen deficiency and potentially involved in...

Autores: Le Nechet, Sandrine; Dubois, Nolwenn; Gouygou, Jean-paul; Berge, Jean-pascal.
If rays are traditionally fished for their caudal fins, the rest of the body is wasted, except part of the skin that can be transformed into leather. Liver oil of the ray, Himantura bleekeri, was characterized in terms of lipid class composition and fatty acid profile. Liver oil content was high and represented 54% of the liver weight (w/w). Neutral lipids were predominant (92%), major components being triacylglycerols (63%). Other neutral lipids identified were hydrocarbons, sterol esters, mono- and di-acylglycerols, free fatty acids, sterols and glyceryl ethers. Polyunsaturated fatty acids of the n-3 series, namely eicosapentaenoic and docosahexaenoic acids, were high (4% and 16%, respectively). Cholesterol was the major component in the sterol fractions...

Essential Fatty Acid Assimilation and Synthesis in Larvae of the Bivalve Crassostrea gigas
Provedor de dados: 5
Autores: Da Costa Gonzalez, Fiz; Robert, Rene; Quere, Claudie; Wikfors, Gary H.; Soudant, Philippe.
Essential fatty acids (EFA) are important for bivalve larval survival and growth. The purpose of this study was to quantitatively assess for the first time through a mass-balance approach dietary EFA incorporation and synthesis within Crassostrea gigas larvae. A first experiment was carried out using two microalgae, Tisochrysis lutea (T) and Chaetoceros neogracile (Cg), as mono- and bi-specific diets. A second experiment using a similar design was performed to confirm and extend the results obtained in the first. Flow-through larval rearing was used for accurate control of food supply and measurement of ingestion. Non-methylene-interrupted fatty acids were synthetized from precursors supplied in the diet: 16:1n-7 and 18:1n-9, mediated by Delta 5...

Microalgae are an outstanding source of high value products with applications in food, feed or biofuel production. Among these promising organisms, the haptophyte Tisochrysis lutea is commonly used as a feed for shellfish and shrimps in aquaculture. Its capacity to produce high amounts of docosahexanoic acid and storage lipids is also of economic interest for nutrition and energy production. Consequently, understanding its lipid accumulation under nitrogen deprivation is of major interest. Here, we aimed to identify Transcription Factors (TFs) involved in the establishment of the mutant phenotype of the 2Xc1 strain of T. lutea, which accumulates double the quantity of storage lipids under nitrogen deprivation than the wild type strain (WTc1). Strains were...

In summer 1979, the natural reproduction of oysters Crassostrea gigas Thunberg, in Marennes-Oleron basin, produced a large number of juveniles which was not the case in summer 1981. If one compares the evolution of the main constituents of the flesh, one can see that, at the beginning of August, before spawning the male oysters in 1981 contained 6,3% less proteins, 34,2% less lipids and 61,2% less glucids than those in 1979 and respectively 12,3%, 21,3% and 69,8% less as far as females are concerned. The energetic value of ash-free dry flesh of female oysters is nearly the same for the two years whereas for male oysters the value is slightly lower in 1981 than in 1979. The total energetic values of male and female oysters show a slight difference between...

Temporal variability in the biochemical composition of sedimentary organic matter in an intertidal flat of the Galician coast (NW Spain)
Provedor de dados: 5
Autores: Cividanes, S; Incera, M; Lopez, J.
Temporal variations and spatial distribution of sedimentary organic matter composition were investigated over a one year period in an intertidal flat of the NW Spain. Sediment samples were collected from 0 to 25 cm depth, every three months, from January 1997 to January 1998 at three tidal levels (high, medium and low). Changes in the elemental and biochemical composition were assessed to gather information on temporal and spatial fluctuations in quantity and quality of sedimentary organic matter potentially available to benthic deposit-feeder nutrition. Organic matter content was significantly higher at the medium tidal level, while minimum values were found at the high tidal level. The different biochemical classes of organic compounds exhibited...

Impact of temperature on larval development and evolution of physiological indices in Crassostrea gigas
Provedor de dados: 5
Autores: Ben Kheder, Rym; Moal, Jeanne; Robert, Rene.
The effect of four temperatures, ranging between 17 degrees C and 32 degrees C, was studied on development and lipid reserve management of Crassostrea gigas larvae. No effect of temperature was found on larval mortality, as high survival (&gt;90%) was recorded before competence at all temperatures studied. Temperature did, nonetheless, have a strong effect on growth and settlement success. At low temperature (17 degrees C), larvae competent to metamorphose were only observed from day 23 and only a low percentage finally achieved metamorphosis (12%). The opposite was seen at temperatures &gt;= 27 degrees C: larval competence appeared at day 18 and led to high rates of metamorphosis (60-90%). This difference at settlement seemed to be linked to larval...

Provedor de dados: 5
Autores: Leray, C.
The authors report the results of physiological and biochemical experiments which confirm the important role player by fish (Salmo gairdneri ) intestinal mucosa in their osmoregulatory process. The ability of the dietary lipids to modulate this function is described. It was demonstrated that the ionic apical permeability of the enterocytes are related to their membrane lipid composition. The importance of the essential fatty acids is emphasized. The time course changes of the apical permeability are of value in improving sea water adaptation, similar conclusions are reported for Nacl supplementation.

Autores: Bac, N; Biagianti, S; Brusle, J.
In the three species Dicentrarchus labrax, Sparus auratus , and Anguilla anguilla an artificial feeding (dry pellets) disturbs liver cells as revealed at ultrastructural level. In hepatocytes, anomalies consist of lipids storage (liposomes) considered as deviation in fatty acids metabolism. Moreover are observed cellular alterations (mitochondrial vacuolization, nuclear pycnosis) related to degenerative process. It is of great interest to understand wether liver modifications are just a reaction to an unbalanced feeding or a true trophic pathology.

Lipid requirements of shrimp
Provedor de dados: 5
Autores: Abramo D', L.
A review of lipid requirements of shrimp and other crustacean species, when applicable, is presented. Qualitative requirements of crustaceans for cholesterol, fatty acids and phospholipids have been documented, but quantitative requirements generally remain undefined. Potential interrelationships between different classes of lipids that may influence requirements as well as differences due to age and species need to be investigated. A more accurate definition of lipid requirements can be achieved by supporting traditional evaluations based upon weight gain and survival with biochemical or histological evidence.

Etude de la composition corporelle de la sole (Solea solea ) au cours du jeune: Influence de la temperature
Provedor de dados: 5
Autores: Richard, P; Djabali, M; Lagardere, Francoise; Lagardere, J.
The effects of starvation on Solea solea at 10 and 20 degree C in sea water, were studied. At 20 degree C fishes start to die on week 4; at 10 degree C they support a longer starvation period (9 weeks). Proximate analysis shows that protein are more steadily used at 20 degree C than at 10 degree C, contrarily to the corporal lipids which are used at the same rate. Starvation results in a reduction of liver lipids and glycogen. This reduction is more pronounced at 20 degree C : 70% of hepatic glycogen is used at this temperature within the first week of starvation against 30% at 10 degree C.

This study was designed to assess in situ the effects of sediment nearness on Crassostrea gigas metabolism. One year-old oysters were reared for 5 months (April-August) in plastic bags on metallic frames at 10 and 60 cm off the sediment at the beginning of April. The management of the energetic resources (storage, consumption) was estimated with respect to biochemical changes of proteins, lipids and carbohydrates. In order to evaluate the  effect of the sediment nearness at cellular level, the metabolic rate was evaluated by assessing pyruvate kinase (PK) and phosphoenolpyruvate carboxykinase (PEPCK) enzyme activities and electron transport system (ETS) activity. The metabolic pathways were assessed by measuring ATP and intermediary metabolites such as...

Ontogeny of the gastrointestinal tract of marine fish larvae
Provedor de dados: 5
Autores: Zambonino, Jose-luis; Cahu, Chantal.
Marine fish larvae undergo major morphological and cellular changes during the first month of life. The ontogeny of the gastrointestinal tract combines these two aspects of the larval development and is very interesting in that the timing of functional changes appears genetically hard-wired. The goal of this paper is to give an overview of the gastrointestinal development process in marine fish larvae, with particular attention to three species: sea bass; red drum; and sole, since the description of gut maturation in fish larvae was initiated during the last decade with these species. During the early stages, marine fish larvae exhibit particular digestive features. Concerning the exocrine pancreas, amylase expression decreases with age from the third week...

Influence of phytoplankton diet mixtures on microalgae consumption, larval development and settlement of the Pacific oyster Crassostrea gigas (Thunberg)
Provedor de dados: 5
Autores: Rico Villa, Benjamin; Le Coz, Jean-rene; Mingant, Christian; Robert, Rene.
Microalgae commonly used as feed for bivalves, Pavlova lutheri (P), Isochrisis affinis galbana (T) and Chaetoceros calcitrans forma pumilum (Cp), were fed to Pacific oyster Crassostrea gigas to assess their nutritional value for larval development and metamorphosis during two experiments. Monospecific, bispecific and trispecific diets were firstly evaluated during 3 weeks from D larvae to young postlarvae. Then bispecific diets, based on different T and Cp proportions, were assessed during a similar period. Concurrently, ingestion was studied through the whole larval and postlarval development for each diet and/or diet mixture. Because lipids are assumed to be a key nutrient for bivalves, biochemical analysis was undertaken on the second set of trials...

Reference diet for crustaceans: Principle of experimentation.
Provedor de dados: 5
Autores: Castell, J.
Feeding trials were conducted with over 22 different crustacean species to compare the potential use of two diets as Standard Reference Diets (SRD) in crustacean research. The two diets (BML 81 S, a casein/albumin based formula developed at the University of California, Bodega Marine Laboratory, and HFX CRD 84, a crab protein concentrate based diet formulated at the Canadian Department of Fisheries and Oceans Halifax Laboratory) were about equal in performance for most species tested. Though neither diet was an ideal SRD, the HFX CRD 84 formulation based upon a purified protein of marine origin was accepted as the interim SRD for use in aquatic crustacean studies.

Nutrition of the seabass Lates calcarifer
Provedor de dados: 5
Autores: Cuzon, Gerard; Chou, R; Fuchs, Jacques.
The Primary Production Department of Singapore (PPD) studies covered the weaning of seabass from fingerlings stage onwards and the dietary protein requirement of early grow-out fish. Dietary protein requirement of early grow-out seabass was demonstrated to be between 40-50%, at dietary lipid level of 12%, using fishmeal protein. Nevertheless fish growth was significantly higher with trashfish feed, but apparent protein retention was significantly better with formulated feed.

Lipid content and fatty acid composition of a marine-derived Trichoderma longibrachiatum strain cultured by agar surface and submerged fermentations
Provedor de dados: 5
Autores: Ruiz, Nicolas; Dubois, Nolwenn; Wielgosz Collin, Gaetane; Du Pont, Thibaut; Berge, Jean-pascal; Pouchus, Yves-francois; Barnathan, Gilles.
A marine-related Trichoderma longibrachiatum strain isolated from mussels in a farming shellfish area was investigated for total lipid (TL) production, total lipid fatty acids (TLFA), and phospholipid fatty acids (PLFA). Fungal biomass was produced from two different marine-like culture ways, on agar surface and submerged fermentations (ASF and SmF, respectively), allowing useful comparisons. ASF produced a rather higher biomass amount than SmF with similar TL content. All fatty acids (FA), identified by gas chromatography-mass spectrometry (GC-MS), were ranged from 14 to 30 carbon atoms. Similar FA compositions were found in TL and phospholipids (PL) from biomasses obtained by both fermentation systems, including oleic (up to 15.3% of total FA mixture for...

Response of a kleptoplastidic foraminifer to heterotrophic starvation: photosynthesis and lipid droplet biogenesis
Provedor de dados: 5
Autores: Jauffrais, Thierry; Lekieffre, Charlotte; Schweizer, Magali; Jesus, Bruno; Metzger, Edouard; Geslin, Emmanuelle.
The aim of this work is to document the complex nutritional strategy developed by kleptoplastic intertidal foraminifera. We study the mixotrophic ability of a common intertidal foraminifer, E. williamsoni, by (1) investigating the phylogenetic identity of the foraminiferal kleptoplasts, (2) following their oxygenic photosynthetic capacity, and (3) observing the modification in cellular ultrastructural features in response to photoautotrophic conditions. This was achieved by coupling molecular phylogenetic analyses and TEM observations with non-destructive measurements of kleptoplast O2 production over a 15-day experimental study. Results show that the studied E. williamsoni actively selected kleptoplasts mainly from pennate diatoms and had the ability to...

Provedor de dados: 5
Autores: Dupraz, Valentin; Ménard, Dominique; Akcha, Farida; Budzinski, Hélène; Stachowski-haberkorn, Sabine.
This study screened binary mixtures of pesticides for potential synergistic interaction effects on growth of the marine microalgae Tisochrysis lutea and Skeletonema marinoi. It also examined the single and combined effects of three of the most toxic substances on microalgal physiology. Single substances were first tested on each microalgal species to determine their respective EC50 and concentration-response relationships. The toxicity of six and seven binary mixtures was then evaluated in microplate experiments on the growth of T. lutea and S. marinoi, respectively, using two mixture modelling approaches: isobolograms and the MIXTOX tool, based on Concentration Addition (CA) or Independent Action (IA) models. Significant cases of antagonism (for both...

L'absorption intestinale des lipides chez la truite arc-en-ciel (Salmo gairdneri )
Provedor de dados: 5
Autores: Vernier, J; Sire, M.
Though the absorption of dietary lipids is much slower in S. gairdneri than in mammals, the mechanism does not differ fundamentally. The long chain fatty acids resulting from intraluminal hydrolysis are esterified by the epithelial cells and transferred as VLDL-like particles and chylomicrons to lymph. The size of granules depends on the nature of the ingested fatty acids. The intracellular stages of this lipoprotein synthesis are defined.

Two different biomasses (100 g multiplied by m super(-2) and 1 kg multiplied by m super(-2)) of oysters were put in identical sea-water ponds, thus leading to different trophic conditions, corresponding to rearing techniques. Changes in growth, biochemical composition and sexual maturation were recorded for two age groups. The first one included 9 month-old oysters and the second one 21 month-old oysters, at the beginning of the experiment. For both age groups, significant differences were observed in growth and biochemical composition. Lipids were accumulated faster for the lower biomass. However, the only difference concerning glycogen was observed on the older oysters. They showed a peak at the lowest biomass and a decrease at the larger biomass. Sexual...

MICROBIAL OILS AND FATTY ACIDS: EFFECT OF CARBON SOURCE ON DOCOSAHEXAENOIC ACID (C22:6 N-3, DHA) PRODUCTION BY THRAUSTOCHYTRID STRAINS
Provedor de dados: 126
Autores: Shene,C; Leyton,A; Esparza,Y.; Flores,L; Quilodrán,B; Hinzpeter,I; Rubilar,M.
Thraustochytrids are marine protists found throughout the world in estuarine and marine habitats. These microorganisms have attracted interest, because their lipids contain different long chain polyunsaturated fatty acids (PUFAs). Those able to produce docosahexaenoic acid (C22:6 n-3, DHA) are the most studied because of the physiological importance of this PUFA in human beings. Their heterotrophic cultivation offers several challenges since biomass, lipid content, and fatty acid profile are dependent on growth conditions. In this work the effects of C source and its concentration on DHA production by different thraustochytrid strains are reviewed. Results obtained by different investigators on the use of alternative and low cost nutrient sources for...

ABSTRACT This study aimed at analyzing the energetic substrate (ES) in the main storage tissues of Steindachneridion parahybae, throughout the reproductive cycle in captivity. Differently from wild, in captivity, feeding is not interrupted during the reproductive period, the females do not spawn spontaneously, and they are sedentary. Adult females were sampled monthly and based on their histology and gonadosomatic index (GSI), ovaries were classified into: previtellogenic (PRV), vitellogenic (VTG), and regression (REG) stages. Ovaries at the VTG stage showed higher protein and lipids levels than at the PRV stage with a positive correlation between these substrates and the GSI. Muscle was the main source of proteins transferred to the ovaries, according to...

Importancia de los lípidos en la reproducción y ontogenia del pez blanco de Pátzcuaro (Chirostoma estor estor)
Provedor de dados: 20
Autores: Aparicio, B.
Para producir larvas de peces con buenos rendimientos, se deben conocer los requerimientos nutricionales de la especie, particularmente en los primeros estadios larvarios. Además, se sabe que la nutrición de los reproductores influye directamente en la calidad de las larvas debido, principalmente, a la cantidad y calidad de lípidos que son transferidos desde la gónada hacia los huevos. El objetivo de este trabajo fue analizar la composición de lípidos en huevos, embriones y larvas de pez blanco de Pátzcuaro (Chirostoma estor estor) con el fin de establecer las bases de los requerimientos nutricionales de lípidos durante el desarrollo larvario del pez blanco. También se determinaron los ácidos grasos en tejidos de reproductores (cerebro, gónada, hígado,...

Comparison of phosphatidylcholine purified from soybean and marine fish roe in the diet of postlarval &lt;i&gt;Penaeus vannamei&lt;/i&gt; Boone
Provedor de dados: 27
Autores: Coutteau, P.; Kontara, E.K.M.; Sorgeloos, P.
The effects of adding two different types of phosphatidylcholine (PC) (purified from soybean lecithin, SPC, or marine fish roe, MPC) on growth, survival and osmotic stress resistance as well as lipid and fatty acid composition of postlarval &lt;i&gt;Penaeus vannamei&lt;/i&gt; was determined. PC was added at a level of 1.5% in a semi-purified diet containing similar levels of essential fatty acids (EFA). A PC-free diet served as the control treatment. The supplementation of 1.5% SPC significantly improved growth and reduced sensitivity to osmotic stress. &lt;i&gt;P. vannamei&lt;/i&gt;-fed MPC showed inferior growth compared to those fed SPC, but yielded better growth and survival than the PC-deprived shrimp. The addition of any of the PC types resulted in a...

Development of a lipid-enrichment technique for &lt;i&gt;Artemia&lt;/i&gt; juveniles produced in an intensive system for use in marine larviculture
Provedor de dados: 27
Autores: Dhont, J.; Lavens, P.; Sorgeloos, P.
Although there exists an obvious inclination to replace live larval food by formulated feeds, &lt;i&gt;Artemia nauplii&lt;/i&gt; are still essential in the larviculture of marine fish species. So far, on-grown &lt;i&gt;Artemia&lt;/i&gt; are rarely used in larviculture although they offer several advantages over &lt;i&gt;Artemia nauplii&lt;/i&gt;: e.g. they contain a higher individual protein and energy content thus improving the fish larvae's energy budget; an equal amount of live food is reached with far less individuals thus a considerable saving of &lt;i&gt;Artemia&lt;/i&gt; cysts; their composition of (n-3) highly unsaturated fatty acids (HUFA) may easily be improved by applying enrichment techniques. This study deals with the development of...

The use of lipid emulsions as carriers for essential fatty acids in bivalves: a test case with juvenile &lt;i&gt;Placopecten magellanicus&lt;/i&gt;
Provedor de dados: 27
Autores: Coutteau, P.; Castell, J.D.; Ackman, R.G.; Sorgeloos, P.
Although information on bivalve nutrition is still very scarce, several studies have demonstrated the importance of lipids, in particular triglycerides, as a source of energy and essential fatty acids in the early life stages. Experimental diets used so far to study bivalve nutrition either heavily pollute the water or are too complex to prepare in a hatchery. The potential use of lipid emulsions as off-the-shelf supplements was evaluated through the analytical verification of the ingestion and incorporation of n-3 highly unsaturated fatty acids (HUFA) by the juvenile sea scallop &lt;i&gt;Placopecten magellanicus&lt;/i&gt; fed lipid emulsions of different fatty acid composition as a supplement to &lt;i&gt;Isochrysis sp.&lt;/i&gt; (clone T-Iso). The average...

Pacific oysters spat (&lt;i&gt;Crassostrea gigas&lt;/i&gt;) were fed an algal diet (&lt;i&gt;Tetraselmis suecica&lt;/i&gt;) whether or not supplemented with emulsions or liposomes rich in 18:1&lt;i&gt;n&lt;/i&gt;-9, 18:2&lt;i&gt;n&lt;/i&gt;-6 and 22:6&lt;i&gt;n&lt;/i&gt;-3. The preferential accumulation and partitioning of the latter fatty acids between the polar and neutral lipids of &lt;i&gt;C. gigas&lt;/i&gt; spat were followed. Additionally, the efficiency of emulsions and liposomes as fatty acid carriers for &lt;i&gt;C. gigas&lt;/i&gt; spat were compared. The incorporation of dietary fatty acids was found to vary substantially according to the fatty acid carrier (emulsions vs. liposomes), the particular fatty acid (18:1&lt;i&gt;n&lt;/i&gt;-9,...

Variations in lipid classes and fatty acid content in tissues of wild &lt;i&gt;Macrobrachium rosenbergii&lt;/i&gt; (de Man) females during maturation
Provedor de dados: 27
Autores: Cavalli, R.O.; Tamtin, M.; Lavens, P.; Sorgeloos, P.
This study describes the variations in total lipid, lipid classes and fatty acids in the midgut gland (MG), ovary, and muscle tissue of wild-caught &lt;i&gt;Macrobrachium rosenbergii&lt;/i&gt; to elucidate the importance of these components during sexual maturation. Mature females were captured in the Mae Klong River, Thailand, from July to September 1998, and divided into five groups according to their ovarian development. Total lipid levels in the ovary increased with maturation, but no concomitant decrease in MG lipids was observed. Thus, the lipid requirements of the developing ovary are thought to be more dependent on the immediate ingestion of dietary lipid than on MG reserves. Higher proportions of neutral lipids (NL), mainly triacylglycerols (TG),...

Abstract: The objective of this work was to determine the effect of photoperiod on the cannibalism, growth, and body composition of giant trahira (Hoplias intermedius) juveniles. A completely randomized design was employed, with four photoperiods - 0L:24D, 6L:18D, 12L:12D, and 18L:6D, hours of light (L): dark (D) - and four replicates, for a period of 90 days. The analyzed parameters were: cannibalism, growth in weight and length, food consumption, feed conversion, protein efficiency rate, muscle growth, and body composition (moisture, lipid, ash, and crude protein). Fish from the 12L:12D photoperiod showed the highest survival rate and no cannibalism, as well as a great uniformity for length and mass values at the end of the experiment. The best...

The objectives of this work were to analyze seeds from 20 trees of aroeira (Myracrodruon urundeuva Fr. All.) of a natural population located in the region of Selvíria, State of Mato Grosso do Sul, Brazil, in order to evaluate their protein, lipid and carbohydrate contents, and to estimate their genetic variation. A completely randomized experimental design consisting of 20 treatments (families) was set up, with two replications. Four types of proteins were detected: albumin (35.0 to 107.3 mg/g seed), globulin (3.4 to 9.3 mg/g), prolamin (60.0 to 135.2 mg/g) and glutelin (118.0 to 286.0 mg/g). The lipid content varied between 200 and 334 mg/g seed. The total sugars also varied (26.5 to 46.3 mg/g seed), with a predominance of polyols (arabinitol, mannitol,...
