Selection Variability for Arg48His in Alcohol Dehydrogenase ADH1B among Asian Populations
Human Biology. 2013. Vol. 85. No. 4. P. 569–577.
Evsyukov A., Ivanov D.
The variant His at codon 48 of the alcohol dehydrogenase gene (ADH1B) results in more efficient ethanol metabolism than with the “typical” codon 48Arg. In this study we introduced selection properties of Arg48His genotypes of ADH1B and estimated fitness in four ethnic-geographical clusters in Asia. Population genetics models were employed that derive observed gene frequencies from fitness relationships among genotypes, to infer the selection pattern of polymorphisms in an indirect manner. The data were analyzed using the model of “complete stationary distribution” by Wright that takes into account random genetic drift, pressure of migrations, mutations, and selection as influential factors of gene frequency. We found that the different population groups showed some variation in the types of selection for Arg48His. Han Chinese from eastern and southeastern China and the Japanese and Korean populations showed stabilizing selection, while the groups from Central Asian and Indochina showed divergent selection. However, all the groups demonstrated a strong positive selection for Arg48His.

Emotion regulation (ER) involves processes by which individuals modulate the intensity, duration, and expression of emotional responses, and its dysregulation is associated with a broad spectrum of psychological disorders. While traditionally conceptualized within psychological frameworks, ER is increasingly recognized as biologically grounded, involving intricate interactions between neurochemical, hormonal, and metabolic systems. This narrative review aims ...

Motor imagery (MI) allows individuals to mentally simulate movements without execution, engaging neural pathways that overlap with those used during real actions. However, how imagery perspective influences corticospinal excitability across different effectors remains unclear. Using neuronavigated transcranial magnetic stimulation (TMS), we compared kinesthetic (KMI), first-person visual (VMI-1PP), and third-person visual (VMI-3PP) imagery of elbow flexion-extension ...

Comprehensive data on natural hazards and their consequences are crucial for effective for risk assessment, adaptation planning, and emergency response. However, many countries face challenges with fragmented, inconsistent, and inaccessible data, particularly regarding local-scale events. To address this data gap in Russia, we developed an end-to-end processing pipeline that scrapes news from various online sources, ...
