To stave off deconditioning after months of inactivity, I walked the grassy fields of Central Park at least three times a week. Sometimes I made it a mile, other times barely four blocks, followed by a two-hour nap. Exercise was welcome because it was a change of disposition. Since lockdown, my apartment had served as…
Anecdotally, at least, some long-haulers are experiencing the type of viral reactivation Klimas describes. In late October, seven months after contracting the coronavirus, Lauren Nichols developed shingles — a reactivation of the virus that causes chickenpox. The episode, which featured burning, “out of this world” nerve pain, sent her to the emergency room. A lesion…
“I’m happy, but it’s a little bit scary,” Emad Moradi, 38, a Kurdish refugee who left Iran in 2013 by boat, said in the hours after his release. He and other refugees were teary-eyed as they tasted their first moments of freedom in years. The release of the men was one of the Australian government’s…
Soon after the face mask became an essential accessory, designers swept in with their own versions: masks made of silk, tweed and satin; decorated with fringe, bows and sequins; for daytime and nighttime; for weddings and political rallies. When it became clear that we’d be wearing masks for a while, some added another element: a…
Black women have higher recurrence and mortality rates than non-Hispanic white women for certain types of breast cancer, according to a University of Illinois Chicago researcher’s study published recently in JAMA Oncology. Dr. Kent Hoskins, associate professor in the UIC College of Medicine’s division of hematology/oncology, and co-leader of the Breast Cancer Research group in…
A new collaborative study from researchers at the Geisel School of Medicine at Dartmouth and the University of Washington (UW) and published in the Proceedings of the National Academy of Sciences (PNAS), reveals unexpected insights into how skin exposure to ultraviolet (UV) light can worsen clinical symptoms in autoimmune diseases such as lupus. Lupus, an…
Doctors may be able to predict their patients’ risks of fatal coronary heart disease more accurately by taking into account the number of adverse social factors affecting them, according to a new study led by researchers at Weill Cornell Medicine and NewYork-Presbyterian. The researchers, whose findings appear Dec. 3 in Circulation, analyzed data from the…
The SARS-CoV-2 virus may enter and replicate in human cells by exploiting newly-identified sequences within cell receptors, according to work from two teams of scientists. The findings from both groups paint a more complete portrait of the various cellular processes that SARS-CoV-2 targets to not only enter cells, but to then multiply and spread. The…
Chimeric Antigen Receptor T-cell therapy–CAR T–has revolutionized leukemia treatment. Unfortunately, the therapy has not been effective for treating solid tumors including childhood cancers such as neuroblastoma. Preclinical studies using certain CAR T against neuroblastoma revealed toxic effects. Now, a group of scientists at Children’s Hospital Los Angeles have developed a modified version of CAR T…
The year 2021 marks the 100th anniversary of a fundamental discovery that’s taught in every biochemistry textbook. In 1921, German physician Otto Warburg observed that cancer cells harvest energy from glucose sugar in a strangely inefficient manner: rather than “burn” it using oxygen, cancer cells do what yeast do — they ferment it. This oxygen-independent…
