Using Syntetically Antyoxidants for Keeping Bacterium Vitality with Stress Abioethics Factors Activity

The influence of syntetical compound with antioxidative activity on increaseing of vitality gram-positive and gram-negative microorgan­ isms under stressful action of antibiotical factors was shown.

Fluorimetric Determination of Rutin, Based on the Complexation with Eu (III) in Micellar Solutions of Surfactants

The quenching of fluorescence of europium chelate (111) with tenoiltrif- toratseton solubilized in the micelles of Bridge-35 with rutin is studied. The possibility of a direct fluorimetric determination of bioantioxidants in the drug «Ascorutin» with a detection limit of 2.9 10   M is shown.

Impact of anthropogenic pollution in Tyumen on herbs vital activity parameters

The purpose of this study was the investigation of lipid peroxidation products and photosynthetic pigment content in cells of herbs of various species in conditions of anthropogenic pollution of Tyumen. The material for the research was collected near different plants of Tyumen: metallurgical, engine, oil refinery, battery manufacturing as well as highway pollution. The following species of plants were analysed: coltsfoot (Tussilago farfara), red clover (Trifolium rubens), chamomile (Matricaria chamomilla) and wild vetch (Vicia cracca).

Chlorophyllin Inhibits Chemiluminescence That Accompanies a Quasi-Hypoxygenase Reaction Catalyzed by the Cytochrome c-Cardiolipin Complex

Lipid peroxidation is a key factor in programmed cell death of various etiologies. This process also occurs when ionizing radiation acts on biological systems. It is the essence of the theory of lipid radiotoxins, which is part of the structural and metabolic theory of the biological action of ionizing radiation. Non-enzymatic lipid peroxidation eventually leads to death by the mechanism of ferroptosis, while enzymatic lipid peroxidation, catalyzed by the cytochrome c-cardiolipin complex, triggers apoptosis along the mitochondrial pathway.
