Some people get really sick from COVID-19, and others don’t. Nobody knows why. Now, a study by investigators at the Stanford University School of Medicine and other institutions has turned up immunological deviations and lapses that appear to spell the difference between severe and mild cases of COVID-19. That difference may stem […]

One of the hallmarks of severe COVID-19 is shortness of breath and significantly reduced levels of oxygen in the blood, called hypoxemia. Upon hospitalization, these patients are administered oxygen in an attempt to bring their levels back up to normal. However, a new study hints that this universal therapy may […]

Anti-androgens are known to increase the effectiveness of radiation therapy for prostate cancer patients, helping to slow the rate at which cancer can repair DNA damage caused by the treatment. Could the same strategy work against glioblastoma, an aggressive brain cancer that quickly grows resistant to radiation? Research led by […]

Many adults seek genetic counseling or opt to send samples of their saliva to different companies, to find out if the specific patterns in their DNA may put them at higher risk for developing the disease. But many doctors and scientists — including National Institutes of Health Director Francis Collins […]

Penn Study Reveals A Molecular Mechanism That Helps The Body Mount Perfectly Balanced Responses to Deadly Infections. Researchers from the Perelman School of Medicine at the University of Pennsylvania have now identified a protein called histone deacetylase 3 (HDAC3) as the orchestrator of the immune system’s inflammation response to infection. […]

A research group from Tel Aviv University (TAU) successfully reduced metastatic spread following tumor removal surgery in colorectal cancer patients. Using a short medication treatment around the time of the surgery, the researchers were able to reduce body stress responses and physiological inflammation during this critical period, preventing the development of metastases […]

Immunotherapy has revolutionized cancer treatment by stimulating the patient’s own immune system to attack cancer cells, yielding remarkably quick and complete remission in some cases. But such drugs work for less than a quarter of patients because tumors are notoriously adept at evading an immune assault. A new study in […]

From birth, the normal human brain rewires itself in response to sensory stimulation from the outside world. To put it simply, it does this by strengthening the connections between certain brain cells through a junction called a synapse. The brain’s ability to change in this way is known as synaptic […]

A diet that includes an average of two servings of plant-based meat alternatives lowers some cardiovascular risk factors compared with a diet that instead includes the same amount of animal meat, Stanford Medicine scientists found. Swapping out red meat for plant-based meat alternatives can lower some cardiovascular risk factors, according […]

Gum disease, especially the kind that is irreversible and causes tooth loss, may be associated with mild cognitive impairment and dementia 20 years later, according to a study published in the July 29, 2020, online issue of Neurology®, the medical journal of the American Academy of Neurology. “We looked at […]

Bifocal contact lenses aren’t just for aging eyes anymore. In nearsighted kids as young as 7 years old, multifocal contact lenses with a heavy dose of added reading power can dramatically slow further progression of myopia, new research has found. In the three-year clinical trial of almost 300 children, a […]

Researchers in the University of Toronto's Faculty of Applied Science & Engineering have discovered a dose threshold that greatly increases the delivery of cancer-fighting drugs into a tumour. The findings, published recently in the journal Nature Materials, provide a potentially universal method for gauging nanoparticle dosage and could help advance a new generation […]
