Here is what I am reading today:
The researchers, John S. Torday, PhD, and Virender K. Rehan, MD, wrote an editorial citing recent studies by Dr. Rehan that found pregnant rats given nicotine produced asthmatic pups that went on to produce their own asthmatic pups, despite the absence of nicotine exposure in the third generation. The findings suggest nicotine can leave heritable epigenetic marks on the genome, which make future offspring more susceptible to respiratory conditions.”
“”When anesthesiologists are taking care of someone in the operating room, they can use the information in this article to make sure that someone is unconscious, and they can have a specific idea of when the person may be regaining consciousness,” says senior author Emery Brown, an MIT professor of brain and cognitive sciences and health sciences and technology and an anesthesiologist at MGH. Lead author of the paper is Patrick Purdon, an instructor of anesthesia at MGH and Harvard Medical School.”
“”In real life and in academic studies, we tend to focus on the harm done to victims in cases of social aggression,” says co-author Richard Ryan, professor of clinical and social psychology at the University of Rochester. “This study shows that when people bend to pressure to exclude others, they also pay a steep personal cost. Their distress is different from the person excluded, but no less intense.”"
“The specific molecule in green tea, (—)-epigallocatechin-3-gallate, also known as EGCG, prevented aggregate formation and broke down existing aggregate structures in the proteins that contained metals—specifically copper, iron and zinc. “A lot of people are very excited about this molecule,” said Lim, noting that the EGCG and other flavonoids in natural products have long been established as powerful antioxidants. “We used a multidisciplinary approach. This is the first example of structure-centric, multidisciplinary investigations by three principal investigators with three different areas of expertise.”"
“The Oxford University researchers, along with Dr David Henderson-Slater of the Nuffield Orthopaedic Centre, report their findings in the journal Nature Communications. They were funded by the Royal Society, Marie Curie Actions, the Wellcome Trust, National Institute for Health Research (NIHR) Oxford Biomedical Research Centre, and the Medical Research Council. ‘Almost all people who have lost a limb have some sensation that it is still there, and it’s thought that around 80% of amputees experience some level of pain associated with the missing limb. For some the pain is so great it is hugely debilitating,’ says first author Dr Tamar Makin of the Centre for Functional Magnetic Resonance Imaging of the Brain (FMRIB) at Oxford University.”
““Humans can build up an impression about somebody just based on what we see,” says author James Anderson, a comparative psychologist at the University of Stirling, UK. The capuchin results suggest that this skill “probably extends to other species”, he says.”
“The human brain can learn to treat relevant prosthetics as a substitute for a non-working body part, according to research published March 6 in the open access journal PLOS ONE by Mariella Pazzaglia and colleagues from Sapienza University and IRCCS Fondazione Santa Lucia of Rome in Italy, supported by the International Foundation for Research in Paraplegie.”
“”The current findings explain the sleepiness of narcolepsy, as well as the depression that frequently accompanies this disorder,” said senior author Jerome Siegel, a professor of psychiatry and director of the Center for Sleep Research at UCLA’s Semel Institute for Neuroscience and Human Behavior. “The findings also suggest that hypocretin deficiency may underlie depression from other causes.”"
