Chronic psychogenic stress represents the major initiating agent of psychoneural diseases including depression. We used informational stress model for the purpose of modelling chronic psychogenic stress and depression. The aim of the research was to study behavior of dominant and submissive rats at different stages of informational stress and during depression state. In order to study anxiety and depressive behavior of rats we used "forced swim", "elevated cross maze" and "open-field" tests. The obtained results showed that chronic stressing procedure performed on rats by using the mentioned "informational" stress model led to the development of depression both in dominant and submissive rats. Stressing procedure caused sharp increase of serotonin concentration in hypothalamus of dominant and submissive rats. Under behavioral depression background, sharp increase of serotonin concentration in hypothalamus has been revealed which is caused by the peculiarities of stress model (by uncontrollable stressor. Specifically, by inevitable electric painful irritation).

In recent years, it was found that lysine malonylation modification can affect biological metabolism and play an important role in plant life activities. Platycodon grandiflorus, an economic crop and medicinal plant, had no reports on malonylation in the related literature. This study qualitatively introduces lysine malonylation in P.

Background: Wall shear stress (WSS) plays a crucial role in the natural history of intracranial aneurysms (IA). However, spatial variations among WSS have rarely been utilized to correlate with IAs' natural history. This study aims to establish the feasibility of using spatial patterns of WSS data to predict IAs' rupture status (i.

Ataxia-Telangiectasia (A-T) is a very rare multisystem disease of DNA repair, associated with progressive disabling neurological symptoms, respiratory failure, immunodeficiency and cancer predisposition, leading to premature death. There are no curative treatments available for A-T but clinical trials have begun. A major limiting factor in effectively evaluating therapies for A-T is the lack of suitable outcome measures and biomarkers.

Background: Stress urinary incontinence (SUI) is a prevalent condition among women, significantly impairing their quality of life. Emerging evidence suggests that metabolic dysfunction may play a role in the development of SUI, although the underlying mechanisms remain unclear. This study aims to examine the association between the cardiometabolic index (CMI), a novel marker of metabolic health, and the risk of SUI in women.

Background: Heart failure (HF) is a heterogeneous clinical syndrome affecting a growing global population. Due to the high incidence of cardiovascular risk factors, a large proportion of the Western population is at risk for heart failure. Oxidative stress and inflammation play a crucial role in the pathophysiology of heart failure with preserved ejection fraction (HFpEF).
