Extracellular Vesicles Help Pass Information Between Cells and Onto Offspring

New studies reveal that small, membrane-bound particles transported between cells have wide-ranging and long-term effects in the brain and throughout the body, from helping neurons communicate to passing the effects of stress onto the next generation. Such extracellular vesicles released from the brain into the blood can also provide a window into brain pathology to help with disease diagnosis. The findings were presented at Neuroscience 2018

Insurance-related Disparities in Timely Access to Gold Standard Dialysis Procedure

A new study found that this period of time without insurance is associated with delays in the placement and use of preferred methods for gaining access to the bloodstream for dialysis. The study, which appears in an upcoming issue of the  Clinical Journal of the American Society of Nephrology  ( CJASN ), also found that this time lag is linked to a higher risk of later dialysis-related infection.

Ribbon Shaped Molecules Represent Protein Structure

A correspondent sent along this item, celebrating the inventor of something that’s so ubiquitous in molecular biology and protein chemistry that you have to think for a moment to realize that it had an inventor: the ribbon diagram. That’s Jane Richardson of Duke, who started there in 1969, back when there were only about 20 entries in what was not yet the PDB because that hadn’t been invented yet, either.

Cryo-electron microscopy Helps In Understanding Amyloid-Based Diseases

The century-old mission to understand how the proteins responsible for amyloid-based diseases such as Alzheimer's, Huntingdon's and Parkinson's work has taken major steps forward in the last 12 months, thanks to a revolution in a powerful microscopy technique used by scientists.

High-powered microscopes using electrons instead of light to 'see' the actual shape of samples put under them, at near atomic-levels of detail, have only recently become available to UK scientists. The study was published in the journal Nature Communications.

Intensive Care Patients Can Eat All They Need

Its long been a concern for doctors caring for critically ill patients – just how important is nutrition to patient survival and how much food is optimal to maximize their recovery? Now combined New Zealand and Australian research called the TARGET study, the largest Intensive Care nutrition trial ever was undertaken.

The study shows current efforts from intensive care staff to ensure critically ill patients receive their recommended ‘goal’ calorie intake may be unnecessary and make no difference to patient survival or recovery.
