Role of Glutathione-S-Transferase Family Genes in Male Infertility.

Polymorphisms of xenobiotic detoxification genes GSTT1 and GSTM1 and activity of glutathione system enzymes were studied in men with infertility. The frequency of deletion variant of GSTT1 gene in men with infertility was by 2 times higher than in fertile men. Deletion variant of GSTM1 gene was 1.

Features of Lipoperoxidation, Antioxidant Defense, and Thiol/Disulfide System in the Pathogenesis of Infertility in Males, Carriers of Nonfunctional Variants of GSTT1 and GSTM1 Gene Polymorphisms.

Comparative analysis of the parameters of LPO, antioxidant defense (AOD), and the thiol/disulfide system was performed in fertile and infertile males of reproductive age carrying different genotypes of the glutathione system genes. Blood plasma, blood hemolysate, and ejaculate served as specimens for biochemical studies. A decrease in glutathione S-transferase activity was found in blood and ejaculate specimens from fertile and infertile carriers of nonfunctional GSTT1(0/0)/GSTM1(0/0) genotypes.

Rapid Access to Oxazine Fused Furocoumarins and in vivo and in silico Studies of theirs Biological Activity.

Background: The synthesis of 1,2-oxazine-fused linear furocoumarins was performed involving the transition metal catalysis reaction of plant coumarin oreoselone derivatives.

Objective And Method: The Pd-catalyzed desulfonative cross-coupling reactions of 2-(tosyl)oreoselone with terminal alkynes and the successive treatment of the obtained 2-(arylethynyl)furocoumarins with an excess of hydroxylamine gave the expected (Z,E)-3-(hydroxyimino)-2-(arylethynyl)furocoumarins with an (Z:E) ratio of about 1:0.5.

[Sperm quality and features of the antioxidant defense system in men living in various regions of Siberia].

Aim: To investigate the quality of sperm, total antioxidant activity, concentrations of -tocopherol and lipid peroxidation in men of reproductive age living in Ulan-Ude, Irkutsk, and Novosibirsk.

Materials And Methods: The analysis of sperm quality included measuring the volume and pH of the ejaculate, sperm cell count, the proportion of motile sperm cells of A and B categories.

Results: Healthy men living in Irkutsk were found to have 34.

[ASSOCIATION OF POLYMORPHIC MARKERS IN GENES OF INNATE IMMUNITY IN PATIENTS WITH PERIODONTITIS AND INFLAMMATORY DISEASES OF UPPER RESPIRATORY TRACT].

Aim: Search of association of polymorphisms in DEFB1, IL-10, TNF-α and TLR2 genes with development of chronic generalized periodontitis in representatives of Ural region (Caucasian race).

Materials And Methods: 142 patients, that were split into 3 groups, took part in the study: a group of patients with periodontitis, a group with frequent inflammatory disease of upper respiratory tract and a comparison group--healthy donors. A study of polymorphic markers was carried out: DEFB1 (-44G/C), DEFB1 (-20A/G), IL-10 (-1082.
