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

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.
Hospitalized ischemic stroke patients with an infection are significantly more likely to be readmitted within 30 days, regardless of the severity of their stroke or other individual patient characteristics, according to new research published in the American Heart Association's journal Stroke
The National Toxicology Program (NTP) concluded there is clear evidence that male rats exposed to high levels of radio frequency radiation (RFR) like that used in 2G and 3G cell phones developed cancerous heart tumors, according to final reports released today
Recent studies of complex brain disorders such as schizophrenia and autism spectrum disorder (ASD) have identified a few "master keys," risk genes that sit at the center of a network of genes important for brain function
Excessive stress during fetal development or early childhood can have consequences for the brain, from increasing the likelihood of brain disorders and affecting an individual's response to stress as an adult to changing the nutrients a mother can pass on to her babies in the womb
Stem cells from patients with Parkinson’s disease and primary progressive multiple sclerosis (PPMS) are soon to voyage into space, and be brought aboard the International Space Station so cell-to-cell interactions in these neurodegenerative diseases can be studied without gravitational forces acting on them.
Researchers carried out a review of studies examining the experiences of over 300 health and social care professionals when supporting parents who are dying and preparing their children for what is happening.
Health professionals require more guidance to prepare and support children when a parent is dying. The study was published in the journal Palliative Medicine.
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.
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.
A drug discovery will increase the safety of animal sedation and anesthesia. Vatinoxan, the pharmacological molecule discovered in the study, reduced the adverse effects of other drugs on the cardiovascular system of canine patients.
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.
