The background activity of neurons in the isolated lumbar semisegment of 14-22 days old white rats was investigated before and after bath application of serotonin (5-HT, 1.10(-8)-1.10(-4) mol/l). 50% investigated neurons in dorsal horn and 70.6% interneurons in the ventral horn reacted on 5-HT. Excitation reactions prevailed. In the dorsal horn 5-HT evoked activation in 62.4% of responding interneurons, depression--in 8.4% and mixed reaction--in 29.2%. In the ventral horn 91.6% of all responses were activation reactions and only 8.4%--biphase ones. 5-HT induced discharges of motoneurons in the ventral root and ventral root depolarization. The data obtained have shown mainly the activation effect of 5-HT on the background activity of spinal neurons.

Background: There is consistent evidence for the contribution of modifiable risk factors to dementia risk, offering opportunities for primary prevention. Yet, most individuals are unaware of these opportunities.
Objective: To investigate whether online education about dementia risk reduction may be a low-level means to increase knowledge and support self-management of modifiable dementia risk factors.

Background: Alzheimer's disease (AD), the leading cause of dementia, is characterized by cognitive decline and the accumulation of amyloid-β (Aβ). It affects millions, with numbers expected to double by 2050. SMOC2, implicated in inflammation and fibrosis, may play a role in AD pathogenesis, particularly in microglial cell function, offering a potential therapeutic target.

Background: Liquid-Liquid Phase Separation (LLPS) is a process involved in the formation of established organelles and various condensates that lack membranes; however, the relationship between LLPS and Ulcerative Colitis (UC) remains unclear.
Aims: This study aimed to comprehensively clarify the correlation between ulcerative colitis (UC) and liquid-liquid phase separation (LLPS).
Objectives: In this study, bioinformatics analyses and public databases were applied to screen and validate key genes associated with LLPS in UC.
