New imaging technique captures real-time brain motion in stunning detail

Magnetic Resonance Imaging (MRI) images are usually meant to be static. But now, researchers from Mātai Medical Research Institute (Mātai), Stevens Institute of Technology, Stanford University, the University of Auckland and other institutions, report on an imaging technique that captures the brain in motion in real time, in 3D and in stunning detail, providing a potential diagnostic tool for detecting difficult-to-spot conditions such as obstructive brain disorders and aneurysms - before they become life threatening.

Study details the complex chemistry and ever-expanding uses of hyaluronic acid

Hyaluronic acid (HA) is more than a buzzword ingredient touted by skincare brands. The "workhorse" capabilities of this biopolymer, which is present in most mammalian tissues, have fascinated scientists for decades.

Study: Second vaccine dose still makes organ transplant recipients vulnerable to COVID-19

In a study published today in the Journal of the American Medical Association (JAMA), Johns Hopkins Medicine researchers show that although two doses of a vaccine against SARS-CoV-2 - the virus that causes COVID 19 - confers some protection for people who have received solid organ transplants, it's still not enough to enable them to dispense with masks, physical distancing and other safety measures.

Vitamin D may play a role in the degree of pain after knee replacement in postmenopausal women

Vitamin D is a critical part of a healthy diet. Among other benefits, it has been shown to protect against bone disease and maintain soft tissue health.

Risk prediction model does not accurately identify lung cancer risks in diverse population

Lung cancer is the third most common cancer in the U.S. and the leading cause of cancer death, with about 80% of the total 154,000 deaths recorded each year caused by cigarette smoking. Black men are more likely to develop and die from lung cancer than persons of any other racial or ethnic group, pointing to severe racial disparities.

Researchers use 3-D bioprinting to create custom-shaped cartilage for use in surgical procedures

A team of University of Alberta researchers has discovered a way to use 3-D bioprinting technology to create custom-shaped cartilage for use in surgical procedures. The work aims to make it easier for surgeons to safely restore the features of skin cancer patients living with nasal cartilage defects after surgery.

Mild depression may predict postoperative delirium in older adults undergoing hip fracture repair

Screening for even mild depressive symptoms before hip fracture repair may be helpful in predicting which patients are at higher risk of developing delirium after emergency surgery, according to results of a new study by researchers from Johns Hopkins Medicine.

Scientists identify genetic mutation associated with exfoliation syndrome known to cause glaucoma

A team of researchers from the Agency for Science, Technology and Research's Genome Institute of Singapore and Bioprocessing Technology Institute, as well as Singapore Eye Research Institute, have identified a genetic mutation (functionally defective CYP39A1 gene) associated with exfoliation syndrome, the most common cause of glaucoma.

Majority of patients who needed surgery after failed TEER required mitral valve replacement

A new study, presented today at the AATS 101st Annual Meeting, and simultaneously published in the Journal of the American College of Cardiology, finds that patients suffering from severe mitral regurgitation should be carefully screened and counselled before undergoing transcatheter edge-to-edge mitral repair (TEER).
