Based on the investigations conducted the contributors to this article arrived at a conclusion to the effect that those residing in lowlands of the Transcarpathian region are exposed to a greater number of factors causing acute cerebral circulatory disturbances than in highlands. This might be one of the reasons for the incidence of stroke to higher in low-lying lands that it is in mountainous areas. Factors due to which acute cerebral disturbances tend to develop need to be eliminated.

Background And Aims: In cirrhosis, some patients display acute encephalopathy without hyperammonemia (NonHep E) which is not considered as overt hepatic encephalopathy (OHE). We aimed to assess the prevalence and characteristics of NonHep E and OHE in cirrhotic patients displaying acute encephalopathy, assess their respective prognosis and compare it to other causes of acute decompensation (AD) with/without hyperammonemia.
Approach And Results: We conducted a retrolective analysis from a prospective cohort of patients hospitalized for AD.

ClpXP is a two-component mitochondrial matrix protease. The caseinolytic mitochondrial matrix peptidase chaperone subunit X (ClpX) recognizes and translocates protein substrates into the degradation chamber of the caseinolytic protease P (ClpP) for proteolysis. ClpXP degrades damaged respiratory chain proteins and is necessary for cancer cell survival.

Importance: Normothermic machine perfusion (NMP) has been shown to reduce peritransplant complications. Despite increasing NMP use in liver transplant (LT), there is a scarcity of real-world clinical experience data.
Objective: To compare LT outcomes between donation after brain death (DBD) and donation after circulatory death (DCD) allografts preserved with NMP or static cold storage (SCS).

The present study aims to examine the effect of 4 h of continuous sitting on cerebral endothelial function, which is a crucial component of cerebral blood flow regulation. We hypothesized that 4 h of sitting may impair cerebral endothelial function similarly to how it affects lower limb vasculature. Thirteen young, healthy participants were instructed to remain seated for 4 h without moving their lower limbs.
