The molluscicidal activity of Bauhinia variegata leaf and Mimusops elengi bark was studied against vector snail Lymnaea acuminata. The toxicity of both plants was time and concentration-dependent. Among organic extracts, ethanol extracts of both plants were more toxic. Toxicity of B. variegata leaf ethanolic extract (96h LC50- 14.4 mg/L) was more pronounced than M. elengi bark ethanolic extract...

We investigate theoretically the site occupancy of Al3+ in the fast-ion-conducting cubic-garnet Li7-3x Al3+x La3Zr2O12 (Ia-3d) using density functional theory. By comparing calculated and measured 27Al NMR chemical shifts an analysis shows that Al3+ prefers the tetrahedrally coordinated 24d site and a distorted 4-fold coordinated 96h site. The site energies for Al3+ ions, which are slightly dis...

Prolonged overexposure to catecholamines causes toxicity, usually credited continuous adrenoceptor stimulation, autoxidation, and the formation of reactive pro-oxidant species. Non-differentiated SH-SY5Y cells were used study possible contribution oxidative stress in adrenaline (ADR)-induced neurotoxicity, as a model predict toxicity this catecholamine peripheral nerves. Cells exposed several c...

Living in an environment that has been altered considerably by anthropogenic activities, fish are often exposed to a multitude of stressors including heavy metals. Copper ions are quite toxic to fish when concentrations are increased in environmental exposures often resulting in physiological, histological, biochemical and enzymatic alterations in fish, which have a great potential to serve as ...

Senior author [email protected] INTRODUCTION Recent advances in understanding the pathophysiology of bone cancer have confirmed the pathologic role of osteoclasts [1]. In addition, the use of suicide gene delivery to tumors by acce...

BACKGROUND Fluid balance affects outcome in critically ill patients. We studied the effect of fluid balance on oxygen exchange by assessing alveolar-arterial oxygen gradient (PA-a O2) in mechanically ventilated patients. Our primary objective was to evaluate the difference in PA-aO2 and the secondary goal was to evaluate the differences in age and mortality rate. MATERIALS AND METHODS This re...

Like other organophosphates, dimethoate is an acetylcholinesterase inhibitor which disables cholinesterase, enzyme essential for central nervous system function. Dimethoate insecticide can be used both indoor and outdoor purposes to eliminate a number of insect pests under different condition. Dimethoate, one the most extensively studied pesticides, may induce many significant changes in fishes...

in this study the lc50 96h values of water-soluble fractions (wsf) of the caspian sea ? exploited crude oil were determined in beluga, huso huso fingerlings. the fingerlings averaged 2.42 ? 0.11 g in weight were exposed to wsf crude oil at concentrations 24.75, 27, 29.25, 31.5, 33.75, 36, 38.25 ppm. the treatments were performed in three replicates and all changes in the specimens were determin...

Fresh water crab was exposed in fluoride water at 96h the rate of oxygen uptake was higher in gills followed by hepatopancreas and muscle. On exposure to fluoride water, tissue respiratory rates decreased, effect on gill tissue appeared to be more pronounced than other tissues under the study. The rate of oxygen uptake in male was higher tha control animal. Rate of oxygen consumption showed a s...
