Researchers find specific type of immune cells in patients with excessive antibody production

The team from Instituto de Medicina Molecular Lisboa, led by Luis Graça, analyzed blood samples from Sjögren syndrome patients, an autoimmune disease that affects the mucous membranes and moisture-secreting glands of the eyes and mouth, and found that these patients have a significant increase in a specific type of immune cells called T follicular regulatory cells (Tfr).

The BEAUTIFUL study: Ivabradine and the reduction of cardiovascular events

The results of the much awaited BEAUTIFUL (morBidity-mortality EvAlUaTion of the If inhibitor ivabradine in patients with CAD and left ventricULar dysfunction) trial have shown that coronary artery disease (CAD) patients with left ventricular dysfunction (LVD) and a heart rate more than 70 bpm have a significantly higher risk of cardiovascular death and other cardiovascular events and in these patients (heart rate above 70 bpm) treatment with ivabradine further reduces the risk of the most important coronary events such as fatal and non-fatal myocardial infarction and coronary revascularisation by one third, even when these patients are already receiving optimal therapy.

High levels of a salivary protein IL-1-beta associated with increased bone loss

Researchers at the University at Buffalo have identified two components of saliva that may serve as the basis for novel tests to determine the risk for future loss of the bone that holds teeth in place.

Atmospheric scientists observe effect of aerosols on clouds at the cleanest place in the world

In order to come one step closer to solving this question, atmospheric scientists from the Leibniz Institute for Tropospheric Research and the Leipzig Institute for Meteorology at Leipzig University will observe the atmosphere at one of the cleanest places in the world for at least a year.
