Anesthesia drugs: Muscle relaxants increase risk of respiratory complications

Sep 17 2018 - 00:09
Muscle relaxants are a necessary part of anesthesia during certain major operations. Studies have, however, hinted at respiratory risks connected with these drugs. POPULAR, a major prospective observational European study supported by the European Society of Anaesthesiology (ESA) and led by the Technical University of Munich (TUM), has confirmed the association between use of muscle relaxants and respiratory complications and assessed the chances of the current avoidance strategies.

Is resveratrol an effective add-on to NSAIDS to treat knee osteoarthritis?

Sep 17 2018 - 00:09
In what researchers state is the first pilot clinical trial to assess the effects of resveratrol on pain severity and levels of inflammatory biomarkers in patients with mild to moderate knee osteoarthritis, the scientists compared treatment with a nonsteroidal anti-inflammatory drug (NSAID) combined with either resveratrol or placebo over 90 days.

Particles surf their own waves, reveal how microbes and cells move through human body

Sep 17 2018 - 00:09
Surf's up for microbes swimming beside red blood cells. New calculations and experiments model for the first time how spherical particles submerged in gooey liquid travel along a flexible rubber sheet; comparable conditions are common in the human body, such as blood cells flowing through a capillary or the journeys of self-propelled microbes. All these particles, it turns out, catch a wave.

Machine learning technique to predict human cell organization published in nature methods

Sep 17 2018 - 00:09
Scientists at the Allen Institute have used machine learning to train computers to see parts of the cell the human eye cannot easily distinguish. Using 3D images of fluorescently labeled cells, the research team taught computers to find structures inside living cells without fluorescent labels, using only black and white images generated by an inexpensive technique known as brightfield microscopy. A study describing the new technique is published today in the journal Nature Methods.
