Aims:Β Our aim was to assess lipid peroxidationΒ β antioxidant protection in menopausal women and men in andropause and to compare these processes in different gender and age groups.Β Materials and methods:74Β women and 37Β men were examined. This study was a prospective, randomized cohort study. Women were divided into perimenopausal group (n=22, mean age 49.03Β±3.13), postmenopausal group (n=15, mean age 54.43Β±4.54) and control (n=37, mean age 34Β±1.2). Men were divided into a group of andropause (n=20, mean age 50.38Β±2.63) and control (n=17, mean age 35.21Β±4.75). Body mass index in the main and control groups was comparable. Questionnaires, clinical examination, assessment of the lipid peroxidation-antioxidant defense system, and the calculation of oxidative stress ratio were conducted to all participants of the study.Β Results:Β In women from the reproductive phase transition to its extinction increases content of compounds with conjugated double bonds by 22% (p0.05) in perimenopause and by 27% (p0.05) in postmenopause, increases content of the ketodienes and coupled trienes by 21% (p0.05) in perimenopause relative to the control group and reduced by 27% (p0.05) in postmenopausal women relative to the group of perimenopause. The antioxidant system in women observed the following changes: decrease in the Ξ±-tocopherol levels in postmenopausal women by 37% relative to control and by 22% (p0.05) to compare perimenopause; reduction of retinol level by 29% (p0.05) in the perimenopause and by 39% (p0.05) in postmenopause relative to control, increasing of the content of GSSG by 18% (p0.05) in postmenopause to compare control. When comparing groups of men statistically significant differences were not found. When comparing the groups according to gender, we revealed in men the increased content of compounds with conjugated double bonds by 38% (p0.05), the GSSG by 13% (p0.05), reduced content of the ketodienes and coupled trienes by 43% (p0,05), Ξ±-tocopherol by 24% (p0.05), SOD activity by 9% (p0.05).Coefficient oxidative stress in perimenopausal women wasΒ 2,5, in postmenopausalΒ β 3,48, in andropauseΒ β 0,97.Conclusions:Β Expressed lipid peroxidation activity is more physiological in andropause than in menopause. Men in andropause have large functional reserves and adaptive capacity than menopausal women.ΠΠ±ΠΎΡΠ½ΠΎΠ²Π°Π½ΠΈΠ΅. ΠΠ·ΡΡΠ΅Π½ΠΈΠ΅ Π²ΠΎΠΏΡΠΎΡΠΎΠ², ΡΠ²ΡΠ·Π°Π½Π½ΡΡ

Relativistic Laser-Matter Interaction and Relativistic Laboratory Astrophysics
The paper is devoted to the prospects of using the laser radiation
interaction with plasmas in the laboratory relativistic astrophysics context.
We discuss the dimensionless parameters characterizing the processes in the
laser and astrophysical plasmas and emphasize a similarity between the laser
and astrophysical plasmas in the ultrarelativistic energy limit. In particular,
we address basic mechanisms of the charged particle acceleration, the
collisionless shock wave and magnetic reconnection and vortex dynamics
properties relevant to the problem of ultrarelativistic particle acceleration.Comment: 58 pages, 19 figure
HIV-associated Tuberculosis: Clinical Case
This case report presents a 35-year-old female who presented with HIV-associated multidrug-resistant tuberculosis. Resistant tuberculosis in HIV-infected patients with immunodeficiency is extremely difficult for effective treatment. Nevertheless, our clinical case showed that the cure of tuberculosis is possible in the late stages of HIV infection with the correct choice of treatment tactics, taking into account the resistance of MBT with the subsequent use of antiretroviral therapy. The progression of HIV infection, against the background of the effective antituberculous therapy, was associated with the patient's refusal to treat the underlying disease
