Molecular and genetic analysis of methicillin-resistant Staphylococcus aureus (MRSA) in a tertiary care hospital in Saudi Arabia.

Methicillin-resistant Staphylococcus aureus (MRSA) continues to pose significant challenges in healthcare settings due to its multi-drug resistance (MDR) and virulence. This retrospective study examines the molecular and resistance profiles of MRSA isolates from a tertiary care hospital in Saudi Arabia, providing valuable insights into regional epidemiology. A total of 190 MRSA strains were analysed to assess antimicrobial susceptibility, genetic diversity, and virulence factors.

Trimethylamine N-oxide in cardiovascular disease: Pathophysiology and the potential role of statins.

Cardiovascular diseases are one of the leading causes of mortality and morbidity worldwide, with the total number of cases increasing to 523 million in 2019. Despite the advent of new drugs, cardiovascular mortality has increased at an alarming rate of 53.7 % from 12.

Multi-level transcriptional regulation of embryonic sex determination and dosage compensation by the X-signal element .

The nuclear hormone receptor is known to be an embryonic X-signal element that represses , the sex-switch gene that is the master regulator of sex determination and dosage compensation. Several prior studies on function have suggested that may have additional downstream roles beyond the regulation of expression. In this study we characterize some of these additional roles of in regulating the dual processes of sex determination and dosage compensation during embryogenesis.

Comparative lifespan and healthspan of nonhuman primate species common to biomedical research.

There is a critical need to generate age- and sex-specific survival curves to characterize chronological aging consistently across nonhuman primates (NHP) used in biomedical research. Sex-specific Kaplan-Meier survival curves were computed in 12 translational aging models: baboon, bonnet macaque, chimpanzee, common marmoset, coppery titi monkey, cotton-top tamarin, cynomolgus macaque, Japanese macaque, pigtail macaque, rhesus macaque, squirrel monkey, and vervet/African green. After employing strict inclusion criteria, primary results are based on 12,269 NHPs that survived to adulthood and died of natural/health-related causes.
