Patients with circulation and blood pressure disorders rely on compression therapy to keep blood from pooling in unwanted places, but it’s notoriously difficult to apply and keep these special wraps in place. If they’re not tight enough, blood won’t return efficiently enough. Too tight, and you restrict blood flow. A …

A group of researchers at the Massachusetts Institute of Technology (MIT) has developed an injectable nanoparticle formulation of the inactivated polio vaccine that releases multiple pulses of stable antigen over time. This new vaccine could make it easier to immunize children in remote regions of Pakistan and other countries where …

Modern medicine has made incredible progress in the treatment of HIV. Years ago, infection with HIV would almost certainly lead to developing AIDS, but treatment can now keep the disease at bay. Even with daily antiretroviral therapy (ART), the pathogen continues to hide in a patient’s cells. Researchers from Japan’s …

In a research article published in the journal Heart, a team of researchers from China and the UK reports that a moderate level of egg consumption (up to 1?egg/day) was associated with a lower incidence of cardiovascular disease in a Chinese population. This prospective cohort study of the general Chinese …

According to new research led Swansea University, UK, nanoparticles derived from leaves of the tea plant (Camellia sinensis) inhibit the growth of lung cancer cells, destroying up to 80% of them. Shivaji et al demonstrated a green, biogenic synthesis route for making quantum dots with 2-5 nm particle size using …

You can finally put those Lego skills from your childhood to work designing medical tests, thanks to a new project from MIT’s Little Devices Lab. Researchers there have developed a set of modular blocks that you can assemble to run various assays with liquid samples. They can measure blood glucose …

Increasing physical activity to recommended levels over as few as 6 years in middle age is associated with a decreased risk of heart failure, according to a study published recently in the journal Circulation. The same study found that as little as six years without physical activity in middle age …

According to a new preclinical study by researchers from the University of Lausanne and Monash University, a diet rich in fiber blunts harmful immune responses in the lungs while boosting antiviral immunity by activating T cells; and these dual benefits are mediated by changes in the composition of gut bacteria, …
