by Roswell Park Comprehensive Cancer Center Credit: Unsplash/CC0 Public Domain Vaping cannabidiol (CBD), a compound found in marijuana, leads to more severe lung damage than vaping nicotine, according to a study by researchers at Roswell Park Comprehensive Cancer Center. Until now, research on the health effects of vaping, or using e-cigarettes, has focused almost exclusively on vaping...

by American Society for Microbiology Credit: CC0 Public Domain A combined treatment strategy targeting SARS-CoV-2 symptoms and severe lung tissue injury is essential to minimize lung sequelae—chronic complications resulting from COVID-19 infection, according to a review published this week in Clinical Microbiology Reviews, a journal of the American Society for Microbiology. Therapy using lung epithelial stem...

K18-hACE-2 humanized mice (2 mo old) were inoculated with SARS-CoV-2 (1×105 p.f.u.) for 2 and 7 d. A, Expression of NLRP3 inflammasome, cleavage of CASP-1/11, IL (interleukin)-1β maturation, and CREB and VE-cadherin expression in...

LOUIS HAVE FOUND THAT SUCH STEM CELLS MULTIPLY DURING AND AFTER A VIRAL RESPIRATORY INFECTION, SOMETIMES TRIGGERING A DETRIMENTAL REMODELING PROCESS THAT CAN CAUSE PERSISTENT LUNG...
by Loyola University Health System Credit: CC0 Public Domain A new study suggests that patients who contract COVID-19 and completely recover from all symptoms do not show evidence of lasting damage to the lungs. The multicenter observational study looked at COVID-19 survivors who experienced asymptomatic, moderate, or severe COVID-19 infections and underwent an unrelated elective lung...
