by Mag. Johannes Angerer, Medical University of Vienna COVID-19, the disease caused by SARS-CoV-2, not only may lead to severe pneumonia but also to thrombosis in the lungs and, subsequently, to multi organ failure involving kidneys, liver and pancreas. These are the findings of a first major series of autopsies in Austria, conducted as part...
By Nick Lavars Central to a lot of scientific research into aging are tiny caps on the ends of our chromosomes called telomeres. These protective sequences of DNA grow a little shorter each time a cell divides, but by intervening in this process, researchers hope to one day regulate the process of aging and the...
Researchers at the Radboud university medical center seem to have found an essential mechanism in the disease process of COVID-19, which has so far been overlooked. If the insight is correct, it probably has important consequences for the treatment of the disease. In an international collaborative effort it is now being investigated whether the new...
by Bob Yirka , Medical Xpress A team of researchers from the Westlake Institute for Advanced Study in Hangzhou, Westlake University and Tsinghua University has produced a high-resolution image of SARS-CoV-2 during the initial phase of infection of a human cell. In their paper published in the journal Science, the group describes how they captured...
by Andrea Laferle, University of Michigan Changing the way individuals are selected to be screened for lung cancer, by considering their probability of getting or dying from lung cancer calculated from risk-prediction models, could prevent 14 percent of lung cancer deaths per year. The Cancer Intervention and Surveillance Modeling Network Lung Working Group (CISNET), which...
by Quinn Eastman, Emory University Scientists have identified a pair of molecules critical for T cells, part of the immune system, to travel to and populate the lungs. A potential application could be strengthening vaccines against respiratory pathogens such as influenza. The findings were published online Thursday, September 26 in Journal of Experimental Medicine. Much...
UT SOUTHWESTERN MEDICAL CENTER DALLAS – Sept. 3, 2019 – Researchers may finally have an answer in the long-running controversy over whether the common surgical mask is as effective as more expensive respirator-type masks in protecting health care workers from flu and other respiratory viruses. A study published today in JAMA compared the ubiquitous surgical...
Ning Ding, M.B.B.S., from the Johns Hopkins University School of Medicine in Baltimore, and colleagues evaluated data from 13,355 participants (aged 45 to 64 years) in the Atherosclerosis Risk In Communities study without PAD, CHD, or stroke at baseline (1987 to 1989). The authors sought to assess the long-term association of cigarette smoking and cessation with the incidence of PAD, CHD,...
by Steven Reinberg, Healthday Reporter Smoking is its leading cause, and while women report smoking less than men, those with COPD have more trouble breathing, more frequent flare-ups and a poorer quality of life, researchers found. “Physicians need to be aware that symptoms for women may be worse for a given level of lung function and that exacerbations may be more frequent,”...
by Adam Pope, University of Alabama at Birmingham New research published in the American Journal of Respiratory and Critical Care Medicinefrom the University of Alabama at Birmingham shows that video telehealth pulmonary rehabilitation interventions reduce 30-day all-cause readmission rates following hospitalization for chronic obstructive pulmonary disease exacerbation. COPD includes a group of diseases, like emphysema and chronic bronchitis, that cause airflow obstruction and breathing-related problems....
