Association between Current Substance Use, Healthy Behaviors, and Depression among Ukrainian College Students.

Depression is a pervasive issue among college students worldwide, yet there is a significant gap in the literature regarding its prevalence and coping strategies in the Ukrainian context. The present study aims to fill this gap by investigating how substance use and health-promoting behaviors relate to depressive symptoms among Ukrainian college students. Health-promoting behaviors are an important strategy to prevent depression, whereas substance use can contribute to depression or make it harder to manage.

[Study of phototrophic purple bacterium Rhodobacter sphaeroides cell morphology of wild-type and ipt-transformant by atomic force and electron microscopy].

A comparative study of phototrophic purple bacterium Rhodobacter sphaeroides cell morphology of wild-type and ipt-transformant was done by atomic force and electron microscopy. It was shown that transformation led to a decrease in the number or total disappearance of the flagella, as well as to changes in the structure of the outer membrane of the bacteria cell wall. On the wild-type cell surface phage-like structures were found, and in transformed cells at their places hollows were identified.
