Pupil response predicts depression risk in kids

by Dr. Jekyll in Lunatic Laboratories

Most parents don’t want to think about their children as depressed, but that can be a deadly mistake. Short of clinical diagnosis through cost prohibitive therapy, there is no real way to tell if a child is at risk for depression. However, according to new research from Binghamton University , how much a child’s pupil dilates in response to seeing an emotional image can predict his or her risk of depression over the next two years....

Link between autoimmune diseases, medications, and a dangerous heart condition

by Dr. Jekyll in Lunatic Laboratories

Mohamed Boutjdir, PhD, professor of medicine, cell biology, and physiology and pharmacology at SUNY Downstate Medical Center, has led a study with international collaborators identifying the mechanism by which patients with various autoimmune and connective tissue disorders may be at risk for life-threatening cardiac events if they take certain anti-histamine or anti-depressant medications. Dr. Boutjdir is also director of the Cardiac Research Program at VA New York Harbor Healthcare System.... Read more »

Restraint and confinement still an everyday practice in mental health settings

by Dr. Jekyll in Lunatic Laboratories

Providers of mental-health services still rely on intervention techniques such as physical restraint and confinement to control some psychiatric hospital patients, a practice which can cause harm to both patients and care facilities, according to a new study from the University of Waterloo. The study found that almost one in four psychiatric patients in Ontario hospitals are restrained using control interventions, such as chairs that prevent rising, wrist restraints, seclusion rooms or acute control medications....

Discovery points to a new path toward a universal flu vaccine

by Dr. Jekyll in Lunatic Laboratories

Flu vaccines can be something of a shot in the dark. Not only must they be given yearly, there’s no guarantee the strains against which they protect will be the ones circulating once the season arrives. New research by Rockefeller University scientists suggests it may be possible to harness a previously unknown mechanism within the immune system to create more effective and efficient vaccines against this ever-mutating virus....

Long-term memories are maintained by prion-like proteins

by Dr. Jekyll in Lunatic Laboratories

Research from Columbia University Medical Center (CUMC) has uncovered further evidence of a system in the brain that persistently maintains memories for long periods of time. And paradoxically, it works in the same way as mechanisms that cause mad cow disease, kuru, and other degenerative brain diseases.... Read more »

REM sleep critical for young brain development; medication interferes

by Dr. Jekyll in Lunatic Laboratories

Rapid eye movement or REM sleep actively converts waking experiences into lasting memories and abilities in young brains reports a new study. The finding broadens the understanding of children’s sleep needs and calls into question the increasing use of REM-disrupting medications such as stimulants and antidepressants.

Novel DNA repair mechanism brings new horizons

by Dr. Jekyll in Lunatic Laboratories

The DNA molecule is chemically unstable giving rise to DNA lesions of different nature. That is why DNA damage detection, signaling and repair, collectively known as the DNA damage response, are needed. A group of researchers discovered a new mechanism of DNA repair, which opens up new perspectives for the treatment and prevention of neurodegenerative diseases.... Read more »

New epigenetic mechanism revealed in brain cells

by Dr. Jekyll in Lunatic Laboratories

For decades, researchers in the genetics field have theorized that the protein spools around which DNA is wound, histones, remain constant in the brain, never changing after development in the womb. Now, researchers from the Icahn School of Medicine at Mount Sinai have discovered that histones are steadily replaced in brain cells throughout life – a process which helps to switch genes on and off....

Women’s faces get redder at ovulation, but human eyes can’t pick up on it

by Dr. Jekyll in Lunatic Laboratories

Previous studies have shown that men find female faces more attractive when the women are ovulating, but the visual clues that allow this are unclear. Now, new research investigating whether it might be to do with subtle changes in skin colour has shown that women’s faces do increase in redness during ovulation, but the levels of change are just under the detectable range of the human eye....

Omega-3 supplements and antioxidants may help with preclinical Alzheimer’s disease

by Dr. Jekyll in Lunatic Laboratories

Here’s more evidence that fish oil supplementation and antioxidants might be beneficial for at least some people facing Alzheimer’s disease. A new report describes the findings of a very small study in which people with mild clinical impairment, such as those in the very early stages of the disease, saw clearance of the hallmark amyloid-beta protein and reduced inflammation in neurological tissues. Although the findings involved just 12 patients over the course of 4 to 17 months, the findings suggest further clinical study of this relatively inexpensive and plentiful supplement should be conducted....

How your brain knows it’s summer

by Dr. Jekyll in Lunatic Laboratories

Researchers led by Toru Takumi at the RIKEN Brain Science Institute in Japan have discovered a key mechanism underlying how animals keep track of the seasons. The study shows how circadian clock machinery in the brain encodes seasonal changes in daylight duration through GABA activity along with changes in the amount of chloride located inside certain neurons....

Rare neurons enable mental flexibility

by Dr. Jekyll in Lunatic Laboratories

Behavioral flexibility — the ability to change strategy when the rules change — is controlled by specific neurons in the brain, Researchers have confirmed. Cholinergic interneurons are rare — they make up just one to two percent of the neurons in the striatum, a key part of the brain involved with higher-level decision-making. Scientists have suspected they play a role in changing strategies, and researchers at OIST recently confirmed this with experiments.... Read more »

A single mutation helped last year’s flu virus gain an advantage over the vaccine

by Dr. Jekyll in Lunatic Laboratories

The 2014-2015 flu vaccine didn’t work as well compared to previous years because the H3N2 virus recently acquired a mutation that concealed the infection from the immune system. A new study reveals the major viral mutation responsible for the mismatch between the vaccine strain and circulating strains. The research will help guide the selection of viral strains for future seasonal flu vaccines.... Read more »
