Will Omicron Leave Most of Us Immune?

By Katherine J. Wu Getty; The Atlantic JANUARY 21, 2022 Even before Omicron hit the United States in full force, most of our bodies had already wised up to SARS-CoV-2’s insidious spike—through infection, injection, or both. By the end of October 2021, some 86.2 percent of American immune systems may have glimpsed the virus’s most infamous protein, according...

How worried should you be about the new COVID subvariant?

by University of Rochester Medical Center Credit: Pixabay/CC0 Public Domain First, there was alpha, then delta, then omicron. And now there’s the so-called “son of omicron,” a subvariant that was flagged by the World Health Organization (WHO) on Monday as a new variant to track. Officially called omicron BA.2, it shares most of its mutations...

In IBS patients, cognitive behavioral therapy modulates brain-gut microbiome and helps relieve symptoms

by Dirk Hoffman, University at Buffalo Classifiers derived from baseline fecal microbiota profiles outperformed those based on clinical/demographic and neuroimaging data to predict CBT response. A Receiver operating characteristic curves of random forest classifiers for CBT response constructed from differentially abundant microbial genera, baseline clinical/demographic data (left panel), or brain data (right panel). The 95%...

What to know about peripheral arterial disease and amputation prevention

by Mark Fleming, University of Kentucky Credit: Pixabay/CC0 Public Domain Early recognition and treatment of peripheral arterial disease (PAD) can prevent leg amputations, but it can also reduce a patient’s risk of stroke, heart attack and death. PAD is the development of blockage in the arteries of the legs. These are very similar to blockages...

Contrary to previous belief, some blood cells stay in tissues for years

by Hans-Knöll-Institut  Resident T cells (purple) survive radiation and chemotherapy in some patients. Donor cells (pink and green) are thus primarily found in the bloodstream. Credit: Daniela Leitner When pathogens enter the human body, a large number of immune cells are quickly on hand to recognize and destroy the invaders. Among them are T cells,...

New tech could reverse diseases, including IBS and diabetes, using intestinal cells

A newly developed technology platform has the potential to treat diseases like diabetes, IBS, and obesity by using enteroendocrine (EE) cells found in human intestinal cells, according to a recent study. Although enteroendocrine cells make up only about 1% of intestinal cells, they produce around fifteen different hormones that play a role in regulating digestion...

Pill derived from human feces treats recurrent gut infections

BY KELLY SERVICK A microbiome-altering therapy cleared recurrent infections with the potentially deadly bacterium Clostridium difficile. BIOMEDICAL IMAGING UNIT/SOUTHAMPTON GENERAL HOSPITAL/SCIENCE SOURCE For people fighting repeat infections of the diarrhea-causing bacterium Clostridium difficile, fecal microbiota transplant (FMT) offers a proven—if unappetizing—solution. Stool from a healthy donor, usually delivered via colonoscopy, can help restore a balanced community...
