Keywords: Background: Uremic anaemia has been the subject of several studies, since it causes serious problems. Decreased RBC production and survival seem to be due to erythropoietin deficiency combined with cell damage. Aims and Objectives: During haemodialysis, complement and leukocyte activation by contact with artificial surfaces promotes the formation of free radicals. However, the cell me...

The aim of this study is to investigate antioxidant enzymes, oxidative stress biomarkers and the acute phase proteins levels for subclinical and clinical pregnancy toxemia and to determine the effect of early diagnosis on the success of curing. According to the results of clinical and biochemical parameters, from 39 ewes, 10 were healthy ewes (control group), 13 ewes had subclinical pregnancy t...

Populus cathayana Rehd., a dioecious tree species, is widely distributed in the northern, central and southwestern regions of China. In poplars, Melampsora larici-populina Kleb. is mainly responsible for rust disease, which is considered to be the world's most important disease of poplars. Yet, little is known about sex-related responses to rust disease in poplars. The purpose of this work was ...

Organophosphate (OP) pesticides such as dichlorvos (DDVP) intoxication has been shown to produce oxidative stress due to the generation of free radicals, which alter the antioxidant defense system in erythrocytes. In this study, the effects of DDVP (1, 10, 100 µM) or DDVP + vitamin C (VC; 10 µM) or vitamin E (VE; 30 µM), on the levels of malondialdehyde (MDA), superoxide dismutase (SOD), catala...

Recent studies have shown that vegetables consumption could lower the risk of diabetes mellitus. Therefore, this study sought to investigate the inhibitory effect of Struchium sparganophora (Ewuro Odo) leaf on key enzyme linked to type-2 diabetes (α-amylase and α-glucosidase) as well as assessing the effect of blanching (a commonly practiced food processing technique) of this leafy vegetable on...

Enzyme degradation of plant cell wall polysaccharides can potentially enhance the release of bioactive phenolics. The aim of this study was to evaluate various combinations of solvent and enzyme, enzyme type (cellulase, pectinase, ß-glucosidase), and hydrolysis time (1, 4, 8, 24 h) on the release of muscadine grape skin and seed phenolics, and their antioxidant activities. Results showed that p...

The present study was designed to evaluate different doses of ellagic acid (EA) in vivo in rats for its potential to modulate hepatic phases I, II, and antioxidant enzymes. EA (10 or 30 mg/kg/day, intragastrically) was administered for 14 consecutive days, and activity, protein, and mRNA levels were determined. Although the cytochrome P450 (CYP) 2B and CYP2E enzyme activities were decreased sig...

fruit and leaves of junipers are commonly used internally as tea and pounded fruits are eaten to lower blood glucose levels in anatolia. thus, we aimed to evaluate antidiabetic and antioxidant potential and the chemical profile of juniperus foetidissima willd. and j. sabina l. in this study. in-vitro antidiabetic activities of leaf and fruit extracts were examined by their inhibitory activity o...

background: diazinon (dzn) is one of the most organophosphates (ops) insecticides that widely used in agriculture and industry. some ops are capable to produce free radicals and induce malfunction in body antioxidant systems. enzymatic and nonenzymatic antioxidants such as superoxide dismutase (sod), catalase (cat) and glutathione s-transferase (gst) and glutathione (gsh) normally counteract da...

This study's purpose was to determine if a correlation exists between cochlear antioxidant activity changes and auditory function after induction of amino-glycoside (AG) ototoxicity. Two groups of five 250-350 g albino guinea pigs served as subjects. For 28 days, albino guinea pigs were administered either 200 mg/kg/day amikacin, or saline subcutaneously. Auditory brainstem response testing was...
