A flow cytometric approach to study intracellular-free Ca2+ in Crassostrea gigas haemocytes ArchiMer
Aton, Emilie; Renault, Tristan; Gagnaire, Beatrice; Thomas Guyon, Hélène; Cognard, C; Imbert, N.
Bivalve haemocytes are essential in defence mechanisms including phagocytosis. They also produce molecules including hydrolytic enzymes and antimicrobial peptides that contribute to pathogen destruction. Although haemocyte activities have been extensively studied, relatively little is known about the intracellular signalling pathways that are evoked during haemocyte activation and especially the role of calcium. Flow cytometry has been used for the first time to define the effect of cell incubation in haemolymph and artificial sea water (ASW) on Pacific oyster, Crassostrea gigas, haemocytes. Cell viability, enzymatic activities (esterases and amino peptidases), phagocytosis and granulocyte percentage were analysed. Viability and some activities were...

Activation of a P2Y4-like purinoceptor triggers an increase in cytosolic [Ca2+] in the red blood cells of the lizard Ameiva ameiva (Squamata, Teiidae) BJMBR
Sartorello,R.; Garcia,C.R.S..
An increasing number of pathophysiological roles for purinoceptors are emerging, some of which have therapeutic potential. Erythrocytes are an important source of purines, which can be released under physiological and physiopathological conditions, acting on purinergic receptors associated with the same cell or with neighboring cells. Few studies have been conducted on lizards, and have been limited to ATP agonist itself. We have previously shown that the red blood cells (RBCs) of the lizard Ameiva ameiva store Ca2+ in the endoplasmic reticulum (ER) and that the purinergic agonist ATP triggers a rapid and transient increase of [Ca2+]c by mobilization of the cation from internal stores. We also reported the ability of the second messenger IP3 to discharge...

AgNO3: a potential regulator of ethylene activity and plant growth modulator Electron. J. Biotechnol.
Kumar,Vinod; Parvatam,Giridhar; Ravishankar,Gokare Aswathanarayana.
The aim of this review is to critically analyze the role of silver nitrate (AgNO3) in modulating plant growth and development. In recent years, basic studies on ethylene regulation opened new vistas for applied research in the area of micro-propagation, somatic embryogenesis, in vitro flowering, growth promotion, fruit ripening, and sex expression. Silver nitrate has proved to be a very potent inhibitor of ethylene action and is widely used in plant tissue culture. Few properties of silver nitrate such as easy availability, solubility in water, specificity and stability make it very useful for various applications in exploiting plant growth regulation and morphogenesis in vivo and in vitro. Silver ion mediated responses seem to be involved in polyamines,...

Al 3+ - Ca2+ INTERACTION IN PLANTS GROWING IN ACID SOILS: AL-PHYTOTOXICITY RESPONSE TO CALCAREOUS AMENDMENTS J. Soil Sci. Plant Nutr.
Meriño-Gergichevich,C; Alberdi,M; Ivanov,A.G; Reyes-Diaz,M.
High aluminum (Al) concentrations as Al3+ represent an important growth and yield limiting factor for crops in acid soils (pH ≤5.5). The most recognized effect of Al-toxicity in plants is observed in roots. However, damages in the upper parts (including stem, leaves and fruits) may also be present. In addition, Al-toxicity triggers an increase in reactive oxygen species (ROS), causing oxidative stress that can damage the roots and chloroplasts, decreasing normal functioning of photo synthetic parameters. Al-toxicity may also increase or inhibit antioxidant activities, which are responsible to scavenge ROS. As result of the negative effects of toxic Al, root metabolic processes, such as water and nutrient absorption, are disturbed with a...

Ameliorative potential of Ocimum sanctum in chronic constriction injury-induced neuropathic pain in rats Anais da ABC (AABC)
KAUR,GURPREET; BALI,ANJANA; SINGH,NIRMAL; JAGGI,AMTESHWAR S..
The present study was designed to investigate the ameliorative potential of Ocimumsanctum and its saponin rich fraction in chronic constriction injury-induced neuropathic pain in rats. The chronic constriction injury was induced by placing four loose ligatures around the sciatic nerve, proximal to its trifurcation. The mechanical hyperalgesia, cold allodynia, paw heat hyperalgesia and cold tail hyperalgesia were assessed by performing the pinprick, acetone, hot plate and cold tail immersion tests, respectively. Biochemically, the tissue thio-barbituric acid reactive species, super-oxide anion content (markers of oxidative stress) and total calcium levels were measured. Chronic constriction injury was associated with the development of mechanical...

Annual changes in serum calcium and inorganic phosphate levels and correlation with gonadal status of a freshwater murrel, Channa punctatus (Bloch) BJMBR
Srivastav,S.K.; Srivastav,A.K..
Adult Channa punctatus murrels of both sexes (60-80 g) were collected locally from Ramgarh Lake during the second week of every month (10 individuals of each sex/month) throughout the year. Blood samples were collected and analyzed for serum calcium and phosphate levels by the methods of Trinder (1960) and Fiske and Subbarow (1925), respectively. Gonads were fixed to judge the state of maturation of the fish. Males exhibited no change in serum calcium levels throughout the year in correlation with testicular maturation. However, serum phosphate levels exhibited a rise in correlation with the increased gonadosomatic index. Females showed marked seasonal changes in serum calcium and phosphate levels which were associated with ovarian maturation...

Oliveira,Renata Gomes de; Freitas Pinheiro,Sandra R; Goulart,Karen B; Pires,Aldrin V; Figueiredo,Frederico de C; Torres-Cordido,Karoll A. Alfonso.
Phosphorus is an important mineral for optimum growth and bone mineralization and is considered the third most expensive nutrient in diets for nonruminants. An experiment was conducted to evaluate the available phosphorus requirements (AP) for meat-type quail in the starter phase (1 to 21 days old). One-day-old, unsexed European quail (375) from the LF1 lineage were used for the study and were housed in pens. The experiment had a completely randomized design, with five treatments (0.13, 0.23, 0.33, 0.43 and 0.53% of AP), each of which included five replicates in 15 birds. Feed intake, weight gain, feed conversion ratio, and the tibial deposition of phosphorus, calcium, and ash were assessed. The AP levels influenced all studied variables. We calculated...

Bell pepper production under saline stress and fertigation with different K+/Ca2+ ratios in a protected environment Agronomy
Silva, Ricardo Carlos Pereira da; Oliveira, Francisco de Assis de; Oliveira, Ademar Pereira de; Medeiros, José Francismar de; Alves, Rita de Cássia; Paiva, Francisco Italo Gomes.
Bell peppers are sensitive to salinity; therefore, it is necessary to find alternatives to reduce saline stress. An experiment was conducted in a greenhouse at Federal Rural University of the Semi-Arid Region, in Mossoró, Rio Grande do Norte State, Brazil, to evaluate the effects of salinity and K+/Ca2+ ratios on bell pepper production. The experimental design consisted of randomized blocks in a 5 x 4 factorial scheme with four replicates, corresponding to five K+/Ca2+ ratios (F1 = 3.3/1, F2 = 2.8/1, F3 = 2.2/1, F4 = 1.8/1, and F5 = 1.5/1) and four salinity levels in the nutrient solution using NaCl (1.75, 3.25, 4.75, and 6.25 dS m-1). The following parameters were evaluated: the number of fruits (total, marketable and unmarketable), the mean weight of...

Soares da Silva Araújo,Cristiane; Martinez Baraldi Artoni,Silvana; Francelino Araújo,Lúcio; Jeferson Quirino Lousada,Mário; Mack Junqueira,Otto; Roque Rodriguez,Anita Isabel.
Two experiments were conducted in order to evaluate the effects of different dietary amino acid and calcium profiles on the bone characteristics of two chicken strains (Avian Farms and Cobb) during the starter phase. At the end of each experiment, 2 chickens of each replicate were sacrificed and their tibiae were collected for analysis of following bone characteristics: bone measurements (weight, length and thickness of the compact and spongy layers) and bone density (bone densitometry). A total of 540 birds were used in each experiment, divided into fully randomized blocks with a 3 x 2 factorial schemes, i. e., 3 amino acid profiles (methionine, lysine and threonine ­ 100%, 125% and 150% of NRC recommendations, 1994) and 2 calcium levels (75% and...

Bradykinin enhances membrane electrical activity of pancreatic beta cells in the presence of low glucose concentrations BJMBR
Moura,A.S..
In most of cells bradykinin (BK) induces intracellular calcium mobilization. In pancreatic beta cells intracellular calcium is a major signal for insulin secretion. In these cells, glucose metabolism yields intracellular ATP which blocks membrane potassium channels. The membrane depolarizes, voltage-dependent Ca2+ channels are activated and the intracellular calcium load allows insulin secretion. Repolarization occurs due to activation of the Ca2+-dependent K+ channel. The insulin secretion depends on the integrity of this oscillatory process (bursts). Therefore, we decided to determine whether BK (100 nM) induces bursts in the presence of a non-stimulatory glucose concentration (5.6 mM). During continuous membrane voltage recording, our results showed...
