Researchers identify genetic abnormalities that drive invasiveness in head and neck cancer

A multi-institutional team of researchers has identified both the genetic abnormalities that drive pre-cancer cells into becoming an invasive type of head and neck cancer and patients who are least likely to respond to immunotherapy.

Study uncovers a novel autoantigen in patients with narcolepsy type 1

Researchers at the University of Helsinki have identified influenza virus peptides that resemble human protein fragments and can cause an immune response against the body’s own cells due to cross-reactivity.

New COVID-19 testing strategy can quicken test results for healthcare workers

Fast turnaround of COVID-19 test results for healthcare workers is critical. Investigators have now developed a COVID-19 testing strategy that maximizes the proportion of negative results after a single round of testing, allowing prompt notification of results.

Traumatic brain injury and Alzheimer's disease share common trajectories

Brain changes in people with Alzheimer's disease and in those with mild traumatic brain injuries (TBIs) have significant similarities, a new USC study shows, suggesting new ways to identify patients at high risk for Alzheimer's.

Researchers assess the theoretical impact of biomarker framework on dementia prediction

One of the biggest challenges in Alzheimer's research is to identify biomarkers that can identify people who are at risk of developing dementia. Biomarkers could be used to screen people so they might be helped before they develop dementia.

Drug synthesized from Kentucky-grown plant shows promise in treating ovarian cancer

A new study from University of Kentucky Markey Cancer researchers shows that Artemisia annua, a plant that has been traditionally used for its anti-malaria components, shows promise in treating ovarian cancer.

Bariatric surgery reduces brain pressure in patients with idiopathic intracranial hypertension

Weight loss surgery is more effective than dieting to reduce brain pressure that can cause blindness in patients with a neurological condition, finds a study led by the University of Birmingham and University Hospitals Birmingham NHS Foundation Trust.

Hypoxia radioactive marker will detect aggressiveness of tumors, eliminating the need for biopsy

Scientific advances in cancer research and new means of diagnosis and treatment have made it possible to cure many patients.

Commonly-prescribed drug for IBD blunts COVID-19 vaccine response

People who take a commonly-prescribed drug for inflammatory bowel disease (IBD) should not assume they are protected after a first dose of COVID-19 vaccine, after a large-scale study found many had poor antibody responses.

Researchers characterize India’s devastating second wave of COVID-19

The COVID-19 pandemic continues to take a heavy toll on human health worldwide. The second wave in India has caught everyone by surprise, showing up the total lack of foresight or precautions. With well over 0.2 million deaths in India, and infections raging out of control, a new study predicts 0.35 million daily cases at the peak of the second wave.

SARS-CoV-2 antibody response robust in nursing home residents after Pfizer-BioNTech vaccine

However, with the waning of the immune response, it is not clear if these older people respond to the vaccine as well as younger individuals do. A recent study explored this question and found that though the antibody levels were somewhat lower in this group, they were still robust. This is a promising observation.

Host cell transmembrane protein MARCH8 targets lysine residues to inhibit SARS-CoV-2 and other viruses

A new study deals with the inhibitory activity of a membrane protein that has broad-spectrum activity against multiple viruses, showing that this is due to its effect on cytoplasmic lysine residue incorporation into replicating virions.

Could pooled testing really improve COVID-19 transmission management and decrease costs?

Pooled testing for SARS-CoV-2 detection is instrumental for increasing test capacity while decreasing test cost. A team of researchers at Yale School of the Environment determined the barriers to implementing pooled testing in United States laboratories. The study showed that many laboratories use many instruments in their testing procedures, varying in the number of samples each can process.

Previous SARS-CoV-2 infection associated with more adverse events following mRNA vaccination

The phase 3 trials of the Pfizer and Moderna COVID-19 vaccines did not include those with a known previous SARS-CoV-2 infection. Recent evidence indicates that mRNA vaccines may induce more adverse events in these individuals. In a recent study, 947 individuals, 265 of which have previously reported SARS-CoV-2 infection, were monitored post-vaccination for adverse events, finding that there could be a link between previous infection and greater incidence of these events.

Cleavage site recognition by SARS-CoV-2 main protease as new antiviral drug target

Many research groups have and are investigating main protease inhibitors as antiviral drugs, and in a paper recently uploaded to the bioRxiv* preprint server, a team of researchers examine the crystal structure of the protein while bound to various viral substrate peptides (P1-4). In doing so, they reveal the way in which the bound peptide sequence can direct and modulate enzyme activity, providing new templates towards antiviral drug design.

Researchers examine potential SARS-CoV-2 antivirals using a drug repurposing library

A new study deals with the screening of the Drug Repurposing Hub (DRH) library for identifying small compounds which are capable of inhibiting SARS-CoV-2 using both in vitro and in vivo experimental studies. These molecules could be used for designing a novel therapeutic system against SARS-CoV-2 infection.
