Using CRISPR to regulate genes in the rat brain

Neuroscientists have used CRISPR/Cas9 genome editing technology to regulate genes in the rat brain. Described in eNeuro, this technique paves the way for researchers to probe genetic influences on brain health and disease in model organisms that more closely resemble human conditions.

Researchers uncover how Gram-negative bacterium delivers toxins that make us sick

Researchers at Binghamton University, State University of New York have uncovered the unique way in which a type of Gram-negative bacterium delivers the toxins that make us sick. Understanding this mechanism may help design better ways to block and eventually control those toxins.

Risk of tick bite potentially leading to red meat allergy is higher than expected

Until now it has been believed that in order for a tick to trigger an allergic immune response to alpha-gal in humans, the tick would need to have recently fed on the alpha-gal-rich blood of a mammal.

Paying more attention to antibiotic dosing could improve clinical outcomes for CF patients

Children and young adults with cystic fibrosis (CF) whose lung infections were treated with suboptimal doses of antibiotics had fewer changes in lung microbial diversity during the IV treatment, and their microbial diversity levels were higher 30 days later, a multi-institutional study that includes Children's researchers shows.

UMass Amherst scientist explores role of citrus peel in decreasing gut inflammation

University of Massachusetts Amherst Professor Hang Xiao, Clydesdale Scholar of Food Science, has received a $1.5 million grant from the National Institutes of Health to study how substances produced in the gut from citrus compounds are involved in decreasing inflammation in the colon.

Researchers develop highly sensitive cell model to study complex effects of anti-inflammatory drugs

Drugs such as ibuprofen or aspirin that relieve pain and lower fever are among the most frequently used drugs worldwide. They are used above all for the treatment of inflammatory reactions. However, in spite of their indisputable effectiveness and frequent use, we do not yet fully understand the underlying mechanisms of these drugs.

Different sleep schedules among teens may have dissimilar effects on cognition and glucose levels

Many adolescent students sleep less than the recommended duration of 8-10 hours a night. It is unclear; however, whether short night sleep combined with an afternoon nap is as good as having the same amount of sleep continuously during the night without a nap.

Mechanism behind how diabetes causes muscle loss revealed

Diabetes mellitus is associated with various health problems including decline in skeletal muscle mass. A research group led by Professor Wataru Ogawa at the Kobe University Graduate School of Medicine revealed that elevation of blood sugar levels leads to muscle atrophy and that two proteins, WWP1 and KLF15, play key roles in this phenomenon.

Novel MRI sensor can peer deep into the brain to detect intracellular calcium activity

Calcium is a critical signaling molecule for most cells, and it is especially important in neurons. Imaging calcium in brain cells can reveal how neurons communicate with each other; however, current imaging techniques can only penetrate a few millimeters into the brain.
