New study reports increased spread of B.1.1.7 variant in Houston, Texas

Research led by Jimmy Gollihar from the CCDC Army Research Laboratory-South in Austin, Texas found the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant B.1.1.7 —first detected last fall in England — increased in Houston, Texas. The B.1.1.7 variant is rapidly spreading with a case doubling time of 6.9 days.

Parents report lower rates of child car seat use in ride-share

A national survey of parents revealed that most parents who used ride-share services did so with their children, but only half of the respondents reported that children who were 8 years or younger traveled in the recommended child car seats or booster seats when in ride-share vehicles.

FDA-approved cancer drug blunts SARS-CoV-2 protein's detrimental effects

University of Maryland School of Medicine (UMSOM) researchers have identified the most toxic proteins made by SARS-COV-2-;the virus that causes COVID-19 – and then used an FDA-approved cancer drug to blunt the viral protein's detrimental effects. In their experiments in fruit flies and human cell lines, the team discovered the cell process that the virus hijacks, illuminating new potential candidate drugs that could be tested for treating severe COVID-19 disease patients.

HSV-1 infection induces strain-specific transcriptional differences in infected neurons

Why do some people with cold sores around their lips experience painful lesions, while others have no symptoms at all, yet still spread the virus? A new study conducted at Penn State finds that these differences could be due to variations in the way certain strains of herpes simplex (HSV-1) -- the virus that causes cold sores, as well as genital herpes -- activate gene expression in neurons.

18-Meter Tapeworm Extracted from Raw Beef Eating Thai Man

Negligence and lack of medical concern has potentially led to this abominably grotesque occurrence as an 18-meter long tapeworm was extracted from the body of an old Thai man, one said to be the longest recorded in Thailand in 50 years. Suffering from “extreme flatulence” and agony of the stomach region, the 67-year-old Thai man […]

GlyNAC could improve many age-associated defects in older humans

A pilot human clinical trial conducted by researchers at Baylor College of Medicine reveals that supplementation with GlyNAC - a combination of glycine and N-acetylcysteine as precursors of the natural antioxidant glutathione - could improve many age-associated defects in older humans to improve muscle strength and cognition, and promote healthy aging.

Intelligent near-infrared vein scanner may make blood draws much easier

Researchers from Skoltech have developed an early prototype of a medical imaging system that uses neural networks to analyze near-infrared images of veins and project a venous pattern onto a patient's body - this may make blood draws much easier and less of a nuisance for patients with difficult access to veins.
