By Rich Haridy Research indicates newer COVID variants stemming from BA.2.86 can infect the lungs more effectively than any variant since Delta Depositphotos A newly published study from researchers at Ohio State University has found the recently emerged BA.2.86 variant of SARS-CoV-2 has a greater propensity for infecting certain lung cells than any prior Omicron variant....
WILEY New research published in The FASEB Journal indicates that e-cigarettes can cause cellular and molecular changes in the lungs. Specifically, prolonged inhalation of e-cigarette aerosols by mice caused changes in the animals’ pulmonary immune cell composition and altered gene and protein levels in the lungs. Investigators found that even low exposure to aerosols from JUUL—a brand...

The National Weather Service says many parts of the the U.S are affected by the extreme cold. Can freezing temperatures...
SEPTEMBER 28TH, 2022 CONN HASTINGS CRITICAL CARE, MATERIALS, MEDICINE, NANOMEDICINE Researchers at the University of California San Diego have developed a microrobot system to treat bacterial pneumonia. The microrobots consist of living algal cells that can swim very effectively in biological fluids, allowing them to navigate throughout the lungs and deliver drugs to difficult-to-reach areas....
by Kara Manke, University of California – Berkeley UC Berkeley postdoctoral scholar Chi Zhu is part of a team of researchers who are developing a new COVID-19 therapeutic that can be administered as a nasal spray. The experimental treatment is effective against all SARS-CoV-2 “variants of concern” and could be readily modified to target other...
by Harish Narasimhan, The Conversation Credit: Pixabay/CC0 Public Domain Viruses that cause respiratory diseases like the flu and COVID-19 can lead to mild to severe symptoms within the first few weeks of infection. These symptoms typically resolve within a few more weeks, sometimes with the help of treatment if severe. However, some people go on...
INSERM (INSTITUT NATIONAL DE LA SANTÉ ET DE LA RECHERCHE MÉDICALE) How can we increase the efficacy of vaccines used to protect against viral respiratory diseases such as influenza and COVID-19? Scientists from Inserm, CNRS and Aix-Marseille Université at the Center of Immunology Marseille-Luminy are opening up new prospects in the field, with the triggering...
The findings could help break the cycle of rapid transmission of TB, the second-leading infectious killer in the world after COVID-19, according to the World Health Organization. The disease mechanisms uncovered in the study could also provide answers about why treatments work in some patients but not others. “These findings implicate strain differences as having an...
Scientists have discovered a brand-new type of cell hiding inside the delicate, branching passageways of human lungs. The newfound cells play a vital role in keeping the respiratory system functioning properly and could even inspire new treatments to reverse the effects of certain smoking-related diseases, according to a new study. © Provided by Live Science Researchers...
MARCH 25TH, 2022 CONN HASTINGS ANESTHESIOLOGY, CARDIOLOGY, CRITICAL CARE, DIAGNOSTICS, PATHOLOGY, RADIOLOGY, SURGERY Researchers at the University of Leeds in the UK have created a magnetic “tentacle robot” that is just 2 mm in diameter, which they hope will be able to navigate through some of the smallest airways in our lungs. At present, a bronchoscope...
