MicroRNAs: Small but Key Players in Viral Infections and Immune Responses to Viral Pathogens.

Since the discovery of microRNAs (miRNAs) in C. elegans in 1993, the field of miRNA research has grown steeply. These single-stranded non-coding RNA molecules canonically work at the post-transcriptional phase to regulate protein expression.

Cellular miR-6741-5p as a Prognostic Biomarker Predicting Length of Hospital Stay among COVID-19 Patients.

Wide variability exists with host response to SARS-CoV-2 infection among individuals. Circulatory micro RNAs (miRNAs) are being recognized as promising biomarkers for complex traits, including viral pathogenesis. We hypothesized that circulatory miRNAs at 48 h post hospitalization may predict the length of stay (LOS) and prognosis of COVID-19 patients.

Congenital Linkage of Lacrimation with Micturition: A Wiring Defect or Just a Spillover?

Association of lacrimation and micturition is rarely reported in the medical literature. It has been hypothesized that abnormal parasympathetic connections occur between the lacrimal nucleus and the pontine micturition center, which give rise to this finding. Here we report a 5-year-old girl who presented with tearing from both eyes whenever she passed urine.
