Oral contraceptive use and tubal ligation linked with lower levels of biomarker for ovarian aging

The long-term use of oral contraceptives and certain methods of tubal ligation (TL) were associated with lower levels of a biomarker for ovarian aging, suggesting an increased risk for early menopause, according to preliminary research by University of Massachusetts Amherst epidemiologists.

SARS-CoV-2 protein NSP2 found to impair microRNA-induced gene silencing in human cells

In a new study, a team of researchers used co-immunoprecipitation and in vitro interaction assays to identify the molecular basis of interaction of SARS-CoV-2 non-structural protein 2 with eIF4E-homologous protein (4EHP)-GRB10-interacting glycine-tyrosine-phenylalanine domain protein 2 complex, involved in microRNA-mediated gene silencing in human cells.

Newly discovered cell type makes survivors of sepsis more vulnerable to infections

Sepsis is the leading cause of death in Brazil's intensive care units (ICUs). Among patients who progress to the severe form of the disease, 40% die, and the survivors often suffer from cardiovascular and neurological complications, as well as a significant decline in immunity lasting for years after they are discharged from hospital.

SARS-CoV-2 destabilizes host RNA to improve fitness

In a study recently published in the journal Nature Communications, scientists have mapped the interactions between SARS-CoV-2 RNA and host RNA. They have observed that the virus heavily methylates its genome using the methylation machinery of the host RNA, leading to an improvement in viral fitness.
