NEW YORK, May 14, 2021 /PRNewswire/ Researchers have discovered new ways in which the COVID-19 virus causes human immune cells to overreact, a deadly part of the disease.
Led by researchers from NYU Grossman School of Medicine and the Perlmutter Cancer Center at NYU Langone Health, the new study found that SARS-CoV-2, the pandemic virus, interacts with specific proteins on immune cells, causing these cells to release abnormally high levels of immune signaling proteins called cytokines (a cytokine storm ). These cytokines, in turn, cause fluid buildup in the lungs and makes it hard to breathe.

A small drug molecule that appears to protect normal tissue from the damaging effects of radiation, may simultaneously be able to boost the cancer-killing effect of radiation therapy, according to a new study led by scientists at University of Iowa, University of Texas Southwestern Medical Center, and Galera Therapeutics, Inc.
The study, published online May 12 in
Science Translational Medicine, suggests that the drug s dual effect is based on a fundamental difference between the ability of cancer cells and healthy cells to withstand the damaging effects of a highly reactive molecule called hydrogen peroxide, which is produced during the dismutation of superoxide.
Ready. Set. Keep going. The race is still on to vaccinate Americans as Covid-19 variants crop up and a long summer in the U.S. looms. Dr. Anthony Fauci urged members of the Senate Health, Education, Labor and Pension Committee on Tuesday to increase vaccination rates if they want to see a return of pre-pandemic life.

WASHINGTON (CN) Shutting down conspiracy theories with aplomb while offering his characteristically blunt assessment of the challenges that still lay in the global war against Covid-19, Dr. Anthony Fauci told members of a Senate health committee that the key lies in greater vaccination rates.

Identifying esophageal adenocarcinoma (EAC) in patients with Barrett s esophagus can improve survival in this population, but some lesions are missed at initial endoscopy.
In a systematic review and meta-analysis recently published in
Clinical Gastroenterology and Hepatology, a group led by Tarek Sawas, MD, MPH, of the University of Texas Southwestern Medical Center in Dallas, and Sachin Wani, MD, of the University of Colorado Anschutz Medical Campus in Aurora, estimated the proportion of post-endoscopy esophageal adenocarcinoma (PEEC) arising in the first year after an index diagnosis of non-dysplastic Barrett s esophagus.
Data came from 52 studies including 145,726 patients with a median follow-up of 4.8 years. What Sawas, Wani, and their colleagues found was disturbing, and they elaborated on this in the following interview with the
