Freshwater fish Cirrhinus mrigala were exposed to lethal concentration (5 mg/L) for 1,2,3,4 days and sublethal concentration (1 mg/L) for 1,7,14,21 days of cypermethrin to examine the enzymes activity, in functionally three different tissues namely, gill, liver and muscle. Activities of Aspartate aminotransferase (AAT), Alanine aminotransferase (AlAT) and Glutamate dehydrogenase (GDH) increased...

The present work details the analysis of heavy-metal and metalloid concentrations in exoskeleton, gill, hepatopancreas, and abdominal muscle tissues of 60 crayfish (Astacus leptodactylus) specimens collected from Lake Hirfanlı, a dam lake located in Kırşehir (Turkey) with a low metal-contamination profile. Concentrations of 11 metals (aluminum [Al], chromium [Cd], manganese [Mn], cobalt [Co], n...

Ammonia nitrogen has been one of the key pollution indicators along Chinese coastline for quite a few years. Our previous studies have proved that ammonia is harmful Ruditapes philippinarum clam in several aspects. Environmental concentrations were found to significantly decrease ATP contents and disturb metabolism, addition reducing potential across mitochondrial membrane gill tissues. Accordi...

Abstract Untreated sewage and industrial wastes from Faisalabad city are disposed to River Chenab through Chakbandi Main Drain (CMD). The present project is planned investigate the effects of this freshwater pollution on body fish Ictalurus punctatus. specimens species were collected upstream downstream entrance CMD into Chenab. Fish gills, liver, kidney muscles dorsolateral regions subjected h...

The physiological responses of juvenile rainbow trout (Oncorhynchus mykiss) to lithium (as LiCl) in moderately hard freshwater (CaCO(3) = 120-140 ppm, Na(+) = approximately 0.6 mM) were studied. The study employed a 15-day step-up exposure regime; 66 microg/L Li for the first 9 days and 528 microg/L for the next 6 days. The concentrations of plasma ions, apolipoprotein AI, total cholesterol, an...

CYP1C is the newest member of the CYP1 family of P450s; however, its physiological significance, inducers, and metabolic functions are unknown. Two full-length alleles of Fundulus heteroclitus CYP1C1 complementary DNA were cloned. The 529 amino acid protein shared the highest amino acid identity with Stenotomus chrysops CYP1C1 (81%). To investigate whether the carcinogen benzo[a]pyrene (BaP) wa...

The goal of the current study was to investigate the differences in epidermal growth factor receptor (EGFR) mutation rates in tumor tissue and pleural effusion specimens from patients with lung adenocarcinoma. PCR amplification and gene sequencing were used to detect EGFR mutations in exons 18, 19, 20, and 21 in tumor tissue and pleural effusion samples from 50 patients with advanced lung adeno...

The activity of alanine aminotransferase (ALAT) and aspartate aminotransferase (AAT) of different tissues of fingerlings of Labeo rohita under the influence of two effluents has been studied. The alanine aminotransferase activity was increased over the control in different exposed periods of tannery and distillery effluent treatments. The alanine aminotransferase in the liver showed increased a...
