The histidine metabolism and transport (his) genes are controlled by a variety of RNA-dependent regulatory systems among diverse taxonomic groups of bacteria including T-box riboswitches in Firmicutes and Actinobacteria and RNA attenuators in Proteobacteria. Using a comparative genomic approach, we previously identified a novel DNA-binding transcription factor (named HisR) that controls the histidine metabolism genes in diverse Gram-positive bacteria from the Firmicutes phylum.

The article analyzes modern legislation regarding artificial termination of pregnancy in countries around the world. Depending on the grounds on which abortion is permitted, five groups of countries are distinguished. Estimates have shown that about 60% of women of reproductive age live in countries with liberal legislation, where abortion is allowed at the request of ...

Malaria control in Malawi relies primarily on long-lasting insecticide-treated nets (LLITNs) and indoor residual spraying (IRS), but transmission remains heterogeneous across districts. Previous research indicates that community-based environmental management strategies, such as routine drainage maintenance, vegetation removal, and effective household waste disposal, may reduce environmental conditions conducive to malaria vector proliferation. This study investigated the ...

Antiviral activity is commonly summarized using endpoint measures such as EC50 or EC90, yet these quantities emerge from a dynamic biological system and depend on viral replication kinetics, host-cell properties, experimental design, and the assay used to quantify infection. Infectious-virus titers, viral RNA, infected-cell fractions, viability measurements, and immune readouts capture different components of the ...

Low-frequency vibrations play an essential role in biomolecular processes involving DNA such as gene expression, charge transfer, drug intercalation, and DNA–protein recognition. However, understanding the vibrational basis of these mechanisms relies on theoretical models due to the lack of experimental evidence. Here we present the low-frequency vibrational spectra of G-quadruplexes (structures formed by four strands ...

The role of escape from the cytotoxic T cell (CTL) response in SARS-CoV-2 evolution remains controversial. Here, we study the origin and spread of SARS-CoV-2 variants whose mutations reduce presentation by the HLA class I alleles common in human populations. We find that 35% of mutations that are characteristic of the variants of concern, and ...
