Sortase proteins play a crucial role as integral membrane proteins in anchoring bacterial surface proteins by recognizing them through a Cell-Wall Sorting (CWS) motif and cleaving them at specific sites before initiating pilus assembly. Both sortases and their substrate proteins are major virulence factors in numerous Gram-positive pathogens, making them attractive targets for antimicrobial intervention. Recognizing the significance of virulence proteins, a comprehensive exploration of their structural and functional characteristics is essential to enhance our understanding of pilus assembly in diverse Gram-positive bacteria. Therefore, this review article discusses the structural features of different classes of sortases and pilin proteins, primarily serving as substrates for sortase-assembled pili. Moreover, it thoroughly examines the molecular-level interactions between sortases and their inhibitors, providing insights from both structural and functional perspectives. In essence, this review article will provide a contemporary and complete understanding of both sortase pathways and various strategies to target them effectively to counteract the virulence.

Male infertility is a common complication of diabetes. Diabetes leads to the decrease of zinc (Zn) content, which is a necessary trace element to maintain the normal structure and function of reproductive organs and spermatogenesis. The purpose of this study was to investigate the effect of metformin combined with zinc on testis and sperm in diabetic mice.

Context: Ionization and adsorption in gas discharge are similar to electrophilic and nucleophilic reactions. The molecular descriptors characterizing reactions such as electrostatic potential descriptors are useful in predicting the electrical strength of environmentally friendly gases. In this study, descriptors of 73 molecules are employed for correlation analysis with electrical strength.

The nutrient germinant receptors (GRs) in spores of Bacillus species consist of a cluster of three proteins- designated A, B, and C subunits- that play a critical role in initiating the germination of dormant spores in response to specific nutrient molecules. The Bacillus cereus GerI GR is essential for inosine-induced germination; however, the roles of the individual subunits and the mechanism by which germinant binding activates GR function remain unclear. In this study, we report the backbone chemical shift assignments of the N-terminal domain (NTD) of the A subunit of GerI (GerIA).

In 2018, Portuguese researchers proposed the "Tool for Quality Assessment of Genetic Counseling," a 5-point Likert scale comprising 50 items across five dimensions, designed to assess genetic counseling from the professional's perspective. This descriptive, cross-sectional study aimed to adapt this tool to Brazilian Portuguese, validate it among Brazilian clinical geneticists, and conduct a preliminary assessment of the quality of genetic counseling in Brazil. The adaptation process involved expert-driven content validation and calculation of the Content Validity Index (CVI) to ensure equivalence between the original and adapted versions.

Mammalian milk contains a variety of complex bioactive and nutritional components and microorganisms. These microorganisms have diverse compositions and functional roles that impact host health and disease pathophysiology, especially mastitis. The advent and use of high throughput omics technologies, including metagenomics, metatranscriptomics, metaproteomics, metametabolomics, as well as culturomics in milk microbiome studies suggest strong relationships between host phenotype and milk microbiome signatures in mastitis.
