Cancer cells fight for their footing by using an ageing gene

22 hours 35 minutes ago
Researchers at the University of Helsinki and the Beatson Institute for Cancer Research in Glasgow have discovered how mutated cells promote their chances to form cancer. Typically, the accumulation of harmful cells is prevented by active competition between multiple stem cells in intestinal glands, called crypts.

Study identifies how COVID-19 linked to Alzheimer's disease-like cognitive impairment

1 day 20 hours ago
A new Cleveland Clinic-led study has identified mechanisms by which COVID-19 can lead to Alzheimer's disease-like dementia. The findings, published in Alzheimer's Research & Therapy, indicate an overlap between COVID-19 and brain changes common in Alzheimer's, and may help inform risk management and therapeutic strategies for COVID-19-associated cognitive impairment.

CDC COVID-19 study shows mRNA vaccines reduce risk of infection by 91 percent for fully vaccinated people

1 week ago
A new CDC study finds the mRNA COVID-19 vaccines authorized by the Food and Drug Administration (Pfizer-BioNTech and Moderna) reduce the risk of infection by 91 percent for fully vaccinated people. This adds to the growing body of real-world evidence of their effectiveness. Importantly, this study also is among the first to show that mRNA vaccination benefits people who get COVID-19 despite being fully vaccinated

Monoclonal antibody prevents HIV infection in monkeys, study finds

1 week 1 day ago
An experimental, lab-made antibody can completely prevent nonhuman primates from being infected with the monkey form of HIV, new research published in Nature Communications shows.

The results will inform a future human clinical trial evaluating leronlimab as a potential pre-exposure prophylaxis, or PrEP, therapy to prevent human infection from the virus that causes AIDS.

NIH researchers identify potential new antiviral drug for COVID-19

1 week 5 days ago
The experimental drug TEMPOL may be a promising oral antiviral treatment for COVID-19, suggests a study of cell cultures by researchers at the National Institutes of Health. TEMPOL can limit SARS-CoV-2 infection by impairing the activity of a viral enzyme called RNA replicase. The work was led by researchers at NIH's Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD). The study appears in Science.

How to obtain immune bovine milk to strengthen the body against COVID-19

1 week 5 days ago
Physiologically, milk contains biocomponents that are highly protective against infections. In light of this, the AGR-149-Infectious Diseases group at the University of Cordoba's Department of Animal Health is doing research that focuses on cow's milk as a possible source of COVID-19 control. The results have been published, partially, in the journal Frontiers in Immunology.

New study may help explain low oxygen levels in COVID-19 patients

1 week 6 days ago
A new study published in the journal Stem Cell Reports by University of Alberta researchers is shedding light on why many COVID-19 patients, even those not in hospital, are suffering from hypoxia--a potentially dangerous condition in which there is decreased oxygenation in the body's tissues. The study also shows why the anti-inflammatory drug dexamethasone has been an effective treatment for those with the virus.

Parler provided echo chamber for vaccine misinformation, conspiracy theories

2 weeks ago
In the early days of COVID-19 vaccine development, a new social media platform provided a place for like-minded people to discuss vaccines, share misinformation and speculate about the motivations for its development. A new study from the University of Kansas shows people flocked to Parler to discuss the vaccines in an echo chamber-type environment, and those conversations can shed light about how to communicate about vaccine efficacy during health crises.
