In this study, we determined the in vitro inhibitory effects of metal ions such as Cu2+, Cd2+, Ag+, and Co2+ on GST enzyme activity. For this aim, GST was purified from C. tarichi Pallas liver with 37.36% yield and 29.304 EU/mg specific activity using the chromatographic method. The Vmax values of liver GST were determined for CDNB and GSH to be 1.245 and 0.562 EU/mL, respectively, and the Km values were found 0.89 and 0.06 mM, respectively, using the Lineweaver–Burk plot.

Chlorella vulgaris has been proposed as a sustainable green feedstock in poultry nutrition due to its ease of cultivation, minimal environmental impact and balanced nutritional composition. However, the majority of studies documents the use of C. vulgaris as a dietary supplement in broilers instead of a feed ingredient.

The organophosphate target enzyme paraoxonase-1 (PON1) has been extensively studied in toxicology. Pesticides are organophosphate compounds that are commonly used in agriculture. They are also used as nerve gases, such as sarin and soman. Therefore, the effects of these compounds on enzymatic activity are well known. In the present study, we investigated the in vitro effects of fenoxaprop-p-ethyl, lambda cyhalothrin, imidacloprid, and dichlorvos pesticides on sheep liver microsomal PON1.

In addition, optimum ionic strength, optimum pH, optimum temperature, and stable pH values were determined for the enzyme in the kinetic studies performed. K M and Vmax were determined for NADPH and cytochrome c. Effects of some metals ions, antibiotics, and some other drugs used in aquarium fisheries on the activity of the enzyme were investigated. IC50 values and Ki values of metals showing an inhibitory effect were calculated.

In this study, some enzymology parameters and some antibiotics affecting the enzyme activity of 6- phosphogluconate dehydrogenase (6PGD) extracted from t the livers of fish from Lake Van (Chalcalburnus tarichi) were investigated because it is an important enzyme-producing NADPH, a reductive power, protecting the cell against the oxidative agents by producing reduced glutathione. The crude enzyme solution was obtained by using the affinity chromatography method.

Thioredoxin reductase (E.C 1.6.4.5.; TrxR) is an enzyme belonging to the flavoprotein family of pyridine nucleotide-disulfide oxidoreductases. In this study, mitochondrial TrxR enzyme was purified from rainbow trout mitochondria. Thanks to the 2 consecutive procedures (preparation of homogenate and 2’,5’-ADP Sepharose 4B affinity chromatography), the enzyme, having the specific activity of 11.9 EU mg protein-1, was purified with a yield of 2.38% and 672-fold. The purity of the enzyme was monitored and the molecular weight of its subunits was calculated as 70 kDa by SDS-PAGE.

The thioredoxin system, found in all living creatures, consists of thioredoxin protein (Trx), thioredoxin reductase enzyme (TrxR), and NADPH. In this study, turkey liver mitochondrial TrxR enzyme with 3.07 EU × mg −1 specific activity was purified 990-fold in a yield of 2.05% using 2’,5’-ADP Sepharose 4B affinity chromatography. The purity of the enzyme was measured and the molecular weight of its subunits was determined to be 45.5 kDa by SDSPAGE. The molecular mass of the enzyme’s natural state was found to be 88 kDa using Sephadex-G 150 gel filtration chromatography.

Xanthohumol is a prenylated chalcone that exhibit antioxidant, anticancer and chemoprotective effects. Its only source in human nutrition is beer, nevertheless a large part of xanthohumol from hops is isomerized by heat to isoxanthohumol and desmethylxanthohumol, from which a racemic mixture of 6- and 8-prenylnaringenins is formed during the beer production. Xanthohumol is also converted to isoxanthohumol by digestion, leading to the formation of 8-prenylnaringenin that is being catalyzed by the enzymes of the intestinal microorganisms as well as liver enzymes.

Glutathione reductase (GR, EC 1.8.1.7) is an antioxidant enzyme and is involved in the reducing reaction of oxidized glutathione. Glutathione and reduced glutathione are very crucial for micro- and macroorganisms because of their barrier function against radicals. Therefore, the aim of this article was to purify GR and evaluate the relationship between purified GR and vitamins. GR was purified from bovine liver using 2’,5’-ADP Sepharose 4B column materials. To check the purity of each subunit of the enzyme, SDS-PAGE electrophoresis was performed and each one was 55 kDa.

The incidence of bilateral corticosteroid-induced osteonecrosis of the femoral head (ONFH) is high. Although the precise mechanism of corticosteroid-induced ONFH development is unclear, hepatic enzyme abnormalities such as low activity of hepatic cytochrome P450 3A could be one cause.

Prostaglandin (PG) E2 plays a critical role in colorectal cancer (CRC) progression, including epithelialmesenchymal transition (EMT). Activity of the rate-limiting enzyme for PGE2 catabolism (15-hydroxyprostaglandin dehydrogenase [15-PGDH]) is dependent on availability of NAD+. We tested the hypothesis that there is intratumoral variability in PGE2 content, as well as in levels and activity of 15-PGDH, in human CRC liver metastases (CRCLM).

High levels of thymidine kinase 1 (TK1) and thymidine phosphorylase (TYMP) are key molecular targets by thymidine therapeutics in cancer treatment. The dual roles of TYMP as a tumor growth factor and a key activation enzyme of anticancer metabolites resulted in a mixed outcome in cancer patients. In this study, we investigated the roles of TK1 and TYMP on a thymidine quinoxaline conjugate to evaluate an alternative to circumvent the contradictive role of TYMP.

7, 12-Dimethylbenz[a]anthracene (DMBA) is acting as immunosuppressor and it serves as a tumor initiator. Tumor promotion can be induced with treatments of 12-Otetradecanoylphorbol-13-acetate (TPA) in some models of two-stage carcinogenesis. This allows for a greatly accelerated rate of tumor growth, making many cancer studies possible. The DMBA damages many internal organs including liver, by inducing the production of reactive oxygen species, DNA-adduct formation and affecting the activities of phase I, II, antioxidant and serum enzymes.

The present study was carried out in TVCC, Hisar on twenty-four dogs affected with venereal granuloma. Affected dogs were divided equally into three groups viz. vincristine therapy (Group I) with 7 day cycle and doxorubicin therapy consisting two groups i.e. Group II with 14 day cycle and group III with 21 day cycle. Blood sample collection was done at weekly interval and before administration of drug i.e. Day 0, 7, 14 in Group I, Day 0, 7, 14, 21, 28 in Group II and Day 0, 7, 14, 21, 28, 35, 42 in Group III.

The present study was undertaken to find the infection rate of Cysticercus tenuicollis in goats slaughtered at Bareilly slaughter house. The chemical and biochemical profile of thirty five randomly collected C. tenuicollis cysts was determined including calcium, phosphorus, glucose, creatinine, triglyceride and activities of two enzymes ALT and AST. Out of a total of 382 goat carcasses examined, 88 (23.01%) were found harbouring C. tenuicollis, with 86.36% in abdominal cavity attached to omentum and mesentry, 11.36% to outer surface of liver and 2.26% diaphragm.

The study aimed to explore the effects of exposure to pesticides on the reproductive health and liver function of females participating in agricultural work. Blood samples were obtained from the thirty-five females (out of one hundred females of reproductive age) who were willing to donate blood. Fifty females matched for age and socio economic status were recruited as a control group to compare levels of hormones (estradiol, progesterone and follicle stimulating hormone), liver enzymes alanine aminotransferase (ALT), and aspartate aminotransferase (AST).
