Polymorphism-Aware Models in RevBayes: Species Trees, Disentangling Balancing Selection, and GC-Biased Gene Conversion.

The role of balancing selection is a long-standing evolutionary puzzle. Balancing selection is a crucial evolutionary process that maintains genetic variation (polymorphism) over extended periods of time; however, detecting it poses a significant challenge. Building upon the Polymorphism-aware phylogenetic Models (PoMos) framework rooted in the Moran model, we introduce a PoMoBalance model.

Distinguishing between models of mammalian gene expression: telegraph-like models versus mechanistic models.

Two-state models (telegraph-like models) have a successful history of predicting distributions of cellular and nascent mRNA numbers that can well fit experimental data. These models exclude key rate limiting steps, and hence it is unclear why they are able to accurately predict the number distributions. To answer this question, here we compare these models to a novel stochastic mechanistic model of transcription in mammalian cells that presents a unified description of transcriptional factor, polymerase and mature mRNA dynamics.

[Intraoperative changes in the peripheral circulation with different methods for reconstructing the arteries of the extremities].

An examination of 192 patients with obliterating atherosclerosis of lower extremities was made who had different reconstructive operation. Intraoperative measurements of oxygen strain in the foot skin and rheography of the shin have shown that temporary compression of large arteries when making vascular anastomoses cause ischemia of extremities, whose degree and duration is dependent on the technique of the technique of the intervention. Advantages of the method of transprosthetic aortotomy such as less duration and lower degree of ischemia were shown.
