Overweight and obesity lead to the formation of a pro-inflammatory phenotype of the adipose tissue macrophages, but it is not known how exactly the balance of STAT1 and STAT6 transcription factors is implemented in the peripheral blood monocytes and how this affects the further polarization process in overweight. The article examines the level and ratio of expression of the STAT1 and STAT6 transcription factors in the polarization of the peripheral blood monocytes depending on the body weight. The study enrolled 20 women and men aged from 18 to 25 years. In terms of BMI, the subjects were divided into the following groups: individuals with normal body weight (BMI 18.50-24.99 kg/m2), represented by 5 women and 5 men; overweight individuals (BMI 25.00-29.99 kg/m2), including 5 men and 5 women. Using standard methods peripheral blood monocytes stimulated by LPS and γIFN, IL-4 was isolated and incubated for 3 and 7 days. PCR method was used to determine the expression level of the stat1 and stat6 genes in incubated cells. The concentration of IL-6 and TGFβ1 was measured in the supernatant on the 7th day of incubation, and TGFβ1 and hs-CRP in the serum of the subjects. The obtained results revealed a significant increase in the level of IL-6 in the supernatant of macrophages stimulated by LPS and γIFN in overweight individuals. The level of hs-CRP in the serum was also significantly higher in overweight individuals. It has been shown that under the conditions of overweight development, there is a significant increase in the level of expression of stat1 and stat6 genes in cells stimulated by IL-4. The obtained data indicate the presence of a preconditioning state of the peripheral blood monocytes with activation of signaling networks mainly in macrophages stimulated by the M2 phenotype under conditions of increased nutrients intake.

Objective: To determine the effect type I collagen gene polymorphism alpha-2 (COL1A2) (rs42524) on the formation of scar tissue that is localized in the head and neck areas. Material and Methods: Sixty patients with scars in different areas of the head and neck were examined. The patients were divided into four subgroups, according to the types of scarring: G I: 15 patients with normotrophic scars; G ІІ : 15 patients with atrophic scars; G ІІІ : 15 patients with hypertrophic scars; and G IV: 15 patients with keloid scars. The age of patients ranged from 17 to 54 years. The single-nucleotide polymorphic site of the COL1A2 (rs42524) gene was detected by a polymerase chain reaction and subsequent analysis of restriction fragment lengths. Pearson's chi-squared test with Yates’s correction and Fischer's exact test were used . Results: There were no significant changes between the control and basic groups (p=0.83) at analyzing the frequencies of G and C alleles. For the G allele, the calculation of odds ratio between the basic and control groups was 0.93 at 95% confidence interval (CI) (0.50-1.75), for the C allele – OR was 1.07 at 95% CI (0.57-2.01) . Conclusion: Our studies may indirectly indicate the activation of the skin’s protective reaction to physiological scarring and dosed scar formation in different areas of the head and neck.

Using the Dutch Eating Behavior Questionnaire (DEBQ) and Three-factor Eating Questionnaire-R18 (TFEQ-RI8), we defined the peculiarities of eating behavior and their impact on quality of life in young people aged 18-25 years. All participants were divided into two groups according to body mass index (BMI). The control group included 41 persons with normal body weight (BMI 18.5-24.9 kg/m2). The group of young adults with increased body weight (BMI over 25 kg/M2) consisted of 27 persons. We found eating behavior disorders in 85,19 % of overweight people and in 41,46 % of persons with normal weight. The restrictive eating behaviors as well as a significant percentage of violations by external type had predominated in overweight individuals by the structure of disorders. The external and restrictive types of eating behavior disorders were predominated in persons with normal weight. Investigation of quality of life using the SF-36 questionnaire showed a significantly decline in the physical role functioning and pain. Index of general physical health component, being not high enough in both groups, was significantly lower in overweight people with 52.70 points against 56.11. We concluded that the eating behavior disorders in persons with normal weight and in overweight people required an individual approach to forming healthy lifestyle and fixing broken food stereotype. It will counteract the further increase of body weight and contribute to improving the quality of life.
