Artificial Intelligence Predicts Genetics of Cancerous Brain Tumors in Under 90 Seconds

Using artificial intelligence, researchers have discovered how to screen for genetic mutations in cancerous brain tumors in under 90 seconds and possibly streamline the diagnosis and treatment of gliomas, a study suggests. In a study of more than 150 patients with diffuse glioma, the newly developed system identified mutations used by the World Health Organization […]

Reducing Total Calories May Be More Effective for Weight Loss than Intermittent Fasting

This study evaluated the association between time from the first meal to last meal with weight change. Nearly 550 adults were enrolled in the study. Participants had at least one weight and height measurement registered in the two years prior to the study’s enrollment period. Overall, most participants (80%) reported they were white adults; 12% […]

Genes Long Known to Control the Formation of Bones Before Birth Also Control Bone Healing Later in Life

A new study pinpointed key Hox genes, specific to each location in the body, as the controllers of stem cells involved in both forming and repairing bone. HOX proteins act like the body’s “zip code,” specifying the position of limbs in the fetus by encoding instructions for transcription factors, which attach to DNA and influence […]

Novel Drug Makes Mice Skinny Even on Sugary, Fatty Diet

When we give this drug to the mice for a short time, they start losing weight. They all become slim,” said Madesh Muniswamy, PhD, professor of medicine in the health science center’s Joe R. and Teresa Lozano Long School of Medicine. Magnesium is the fourth most abundant element in the body, and plays many key […]

Research Finds Hope in Stem Cell Therapy for Perianal Fistulas in Patients with Crohn’s Disease

In a clinical trial, researchers loaded stem cells from a patient’s own fat tissue onto a bioabsorbable plug that was then surgically implanted to close an anal fistula tract. They followed the patients for one year and reported results. Perianal fistulas are painful tunnels between the intestine and the skin that often do not go […]

High Doses of Selenium May Protect Against Ovarian Cancer

A new study, published in Redux Biology, finds that high doses of selenium have anti-cancer properties. Selenium has been investigated as a potential anti-cancer agent for the reduction of the risk of different malignancies including colorectal, lung, and prostate cancer, as well as an adjuvant to conventional anti-tumour therapies. Such use is limited, however, by […]

Fever Alters Immune Cells So they Can Better Reach Infections

Fever is known to help power up our immune cells, and scientists in Shanghai have new evidence explaining how. They found in mice that fever alters surface proteins on immune cells like lymphocytes to make them better able to travel via blood vessels to reach the site of infection. Chen and colleagues discovered that fever […]
