Ethylenediurea (EDU), N[2-(2-oxo-l-imidazolidinyl) ethyl]-N'-phenylurea is known to prevent ozone (03) damage to leaf tissues. However, the mechanisms of protection are unclear. We tested the hypothesis that EDU protects against 03 damage by scavenging hydroxyl free radicals (OH). An in vitro study involving the use of high-performance liquid chromatography equipped with an electrochemical dete...

Laboratory studies were conducted to determine the effects of different concentrations of Cu, Cd, Zn and mixture (equal concentrations from the three heavy metals) on growth and some oxidative stress (catalase and glutathione reductase) on Scenedesmus obliquus (microalgae) after exposure for 24, 48, and 96 h. In addition, the uptake of Cu, Cd and Zn were determined in the culture medium after 2...

PURPOSE To investigate associations between enzyme activity of glutathione reductase (GR) with and without added flavin adenine dinucleotide (FAD), glutathione peroxidase (GPX), and 6-phosphogluconic dehydrogenase (6PGDH) in the lens epithelium collected at surgery, and some nutritional and biochemical variables determined in the same individuals during the Italian-American Case-Control Study o...

The role of exogenous spermidine (Spd) in alleviating low temperature (LT) stress in mung bean (Vigna radiata L. cv. BARI Mung-3) seedlings has been investigated. Low temperature stress modulated the non-enzymatic and enzymatic components of ascorbate-glutathione (AsA-GSH) cycle, increased H₂O₂ content and lipid peroxidation, which indicate oxidative damage of seedlings. Low temperature reduced...

In this work the influence of the nodulation of pea (Pisum sativum L.) plants on the oxidative metabolism of different leaf organelles from young and senescent plants was studied. Chloroplasts, mitochondria, and peroxisomes were purified from leaves of nitrate-fed and Rhizobium leguminosarum-nodulated pea plants at two developmental stages (young and senescent plants). In these cell organelles,...

Sphingobium wenxiniae JZ-1 utilizes a wide range of pyrethroids and their metabolic product, 3-phenoxybenzoate, as sources of carbon and energy. A mutant JZ-1 strain, MJZ-1, defective in the degradation of 3-phenoxybenzoate was obtained by successive streaking on LB agar. Comparison of the draft genomes of strains JZ-1 and MJZ-1 revealed that a 29,366-bp DNA fragment containing a putative angul...

To discover novel antimalarial and anticancer compounds, we carried out a genome analysis, bioassay, metabolite profiling, molecular docking of marine sediment actinobacteria strain GMY01. The whole-genome sequence analysis revealed that Streptomyces sp. GMY01 (7.9 Mbp) is most similar to sennicomposti RCPT1-4T with an average nucleotide identity (ANI) ANI based on BLAST+ (ANIb) values 98.09 97...

Objective: Liver transplantation using a living donor (LDLT) is currently the most popular method used in worldwide. Appropriate biomarkers that predict graft status should be to detect early post-transplant complications may lead rejection reaction. Material and Method: The study involved total of 44 liver recipients donors, from whom preoperative blood samples were taken immunoassay spectroph...

Environmental contamination at shooting ranges is a widely known ecological problem. The aim of the study was to evaluate extent and ecotoxicity range soil assessing physiological biochemical effects on earthworm Eisenia fetida (Savigny). Adult E. were exposed soils collected from different distances for 28 days. High concentrations Pb (53023 mg kg−1), increased Ni (12 kg−1) Sb (600 significant...

The important and increasing application of aluminum motivated us to determine whether and in what way does the antioxidative status of erythrocytes in aluminum acute poisoned animals change by studying the metabolism of superoxid dismutase (SOD), glutathione reductase (GR), reduced glutathione (GSH) and malonil dialdehyde (MDA). The experiment involved desert mice (gerbils) who received intrap...
