Abstract The present study evaluated the protective effects of silymarin extract (SIE) on cadmium chloride toxicity in common carp, Cyprinus carpio . Four experimental groups were considered for experiment including: SIE 0 (control): non-SIE-supplemented fish, 1 : fish supplemented with 400 mg SIE/kg diet, 2 1400 3 2400 diet. Fish fed diet 60 days and then exposed to (1.5 mg/l or 25% LC50-96 h)...

OBJECTIVE To identify dietary and environmental risk factors for hyperthyroidism in cats. DESIGN Case-control study. ANIMALS 100 cats with hyperthyroidism and 163 control cats. PROCEDURE Medical records were examined, and owners completed a mailed questionnaire. Data collected included information regarding demographic variables, environmental exposures, and diet, including preferred flav...

The present study was undertaken to evaluate the influence of butachlor, a widely used herbicide, on antioxidant enzyme system and lipid peroxidation formation in African cat fish (Clarias gariepinus). Fish were exposed to sub-lethal concentrations of butachlor 1, 2, 2.5 ppm and sacrificed 24hrs after treatment. A significant increase in malondialdehyde formation was observed in the liver, kidn...

Despite recent progress achieved in elucidating the mechanisms underlying local adaptation to pollution, little is known about the evolutionary change that may be occurring at the molecular level. The goal of this study was to examine patterns of gene transcription and biochemical responses induced by metal accumulation in clean yellow perch (Perca flavescens) and metal depuration in contaminat...

The genetic map of the domestic cat has been developed as a model for studying both feline analogues of human genetic disease and comparative genome organization of mammals. We present here the results of syntenic mapping of 35 genes based upon concordant occurrence of feline gene homologues with feline chromosomes and previously mapped loci in a panel of 41 rodent x cat somatic cell hybrids. T...

INTRODUCTION Cypermethrin causes its neurotoxic effect through voltage-dependent sodium channels and integral protein ATPases in the neuronal membrane. Brain and nerve damage are often associated with low residual level of pesticides. In vitro and in vivo studies have also shown that pesticides cause free radical-mediated tissue damage in brain. Propolis has antioxidant properties. The main che...

Sperata aor commonly called as long- whiskered cat fish or "Bada Tengan" in local fish markets harboured one new and one previously known species of genus Thaparocleidus Jain, 1952, along with two species of Cornudiscoides Kulkarni, 1969, infesting gills. Thaparocleidus aori (Rizvi, 1971) Lim, 1996, was earlier described by Rizvi therefore was briefly recorded in the present study, except the e...

In the aquatic environment, despite the presence of constitutive or enhanced antioxidant defence systems, increased levels of oxidative damage will occur in organisms exposed to contaminants that stimulate the production of reactive oxygen species. The increased ROS production and subsequent oxidative stress has been associated with a pollutant-mediated mechanism of toxicity in fish organs. The...

Bacillus cereus VCRC 641 was found to be an alternate larvicidal bacterial agent which newly isolated from fresh water fish, Clarias batrachus (walking cat fish). The protein responsible for mosquito toxic effect separated and purified by Sephacryl S-200 column chromatography NATIVE PAGE. It observed that a unique with molecular weight of 70kDa the factor killing effect. Further analysis liquid...

These studies show that miR-122, a 22-nucleotide microRNA, is derived from a liver-specific noncoding polyadenylated RNA transcribed from the gene hcr. The exact sequence of miR-122 as well as the adjacent secondary structure within the hcr mRNA are conserved from mammalian species back to fish. Levels of miR-122 in the mouse liver increase to half maximal values around day 17 of embryogenesis,...
