By far the most important process in cell development is how cells divide and then enlarge in order to multiply. A research team headed by Freiburg medical scientist Prof. Dr. Robert Grosse has now discovered that bundled fibers of actin within a cell nucleus play an important part in how they enlarge after division. Fibers of the structural protein actin stabilize the outer form of the cell and transport substances into a cell. The mechanisms that influence the growth of the cell nucleus after division were less well known by scientists.
We process language differently depending on whether we are reading alone or in the company of another person, according to a study carried out by teachers and researchers from the Complutense University of Madrid (UCM) and the Carlos III Health Institute (ISCIII) and published in Cortex.
The results of recording electrical activity in the brain indicated that when we read in company, our language processing is more heuristic, i.e. more global, controlled, integrated and possibly more creative.
September 22, 2020 - A geocoding approach - linking routinely collected public health data to neighborhood socioeconomic factors - shows consistently higher rates of COVID-19 illness and death among people living in more-disadvantaged communities, reports a study in the November/December Journal of Public Health Manageme
Philadelphia, September 22, 2020 - Researchers from Children's Hospital of Philadelphia (CHOP) have shown there may be key genetic differences in the causes of attention-deficit hyperactivity disorder (ADHD) between African Americans and people of European ancestry, which may play an important part in how patients of different ethnic backgrounds respond to treatments for this condition. The findings were published online by the journal Scientific Reports.
Oral pre-exposure prophylaxis (PrEP) is a highly effective method of reducing risk for HIV, yet use of PrEP is uniformly low, especially among women. As a result, researchers have developed long-acting injectable (LAI) versions of PrEP, one version of which was recently shown to be superior to oral PrEP in Phase 3 trials. A new study among women at high risk for HIV explored their hesitancy to use PrEP overall, as well as their interest in and willingness to use LAI PrEP.
One of the major symptoms of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is post-exertional malaise (PEM), the worsening of symptoms after physical or mental activities. Using their own words and experiences, people with ME/CFS described how debilitating PEM can be in a study in Frontiers in Neurology. This is the first publication to come out of the National Institutes of Health's intramural post-infectious ME/CFS study.
New insight on how people with retinal degenerative disease can maintain their night vision for a relatively long period of time has been published today in the open-access eLife journal.
ROCHESTER, Minn. -- A new study published in the Journal of the National Cancer Institute is the first to examine the opinions and experiences of clinical oncologists working at a major medical center on the Federal Right to Try (RTT) law.
Widespread COVID-19 testing may be an obvious way to control an outbreak in a long-term care facility. But communication among the facility's staff, its residents and the residents' family members is crucial, too.
A new study led by Carl Shrader, a physician and researcher in the Department of Family Medicine in the West Virginia University School of Medicine, revealed the role that communication played in quashing a COVID-19 outbreak at Sundale, a long-term care facility in Morgantown.
Boston, Mass. - A new review article from Beth Israel Deaconess Medical Center (BIDMC) shows people who are biologically male are dying from COVID-19 at a higher rate than people who are biologically female. In a review published in Frontiers in Immunology, researcher-clinicians at BIDMC explore the sex-based physiological differences that may affect risk and susceptibility to COVID-19, the course and clinical outcomes of the disease and response to vaccines.
DETROIT - Dermatology researchers at Henry Ford Health System, in collaboration with a team at the University of Michigan, have demonstrated that certain N95 respirators tainted with COVID-19 can be effectively and safely decontaminated for reuse using ultraviolet-C light (UV-C), a method commonly utilized for treating rare skin diseases.
With personal protective equipment still in short supply, researchers at the University of Cincinnati examined what common household fabrics might work best as a face covering.
Next to a single-use N95 respirator or surgical mask, UC found the best alternative could be made by a hungry little caterpillar. Silk face masks are comfortable, breathable and repel moisture, which is a desirable trait in fighting an airborne virus.
Achieving herd immunity to COVID-19 is an impractical public health strategy, according to a new model developed by University of Georgia scientists. The study recently appeared in Proceedings of the National Academy of Sciences.
Controlling COVID-19 has presented public health policymakers with a conundrum:
Using a combination of demographic and clinical data gathered from seven weeks of COVID-19 patient care early in the coronavirus pandemic, Johns Hopkins researchers today published a "prediction model" they say can help other hospitals care for COVID-19 patients -- and make important decisions about planning and resource allocations.
INDIANAPOLIS--Indiana University School of Medicine researchers are learning more about ways to prevent infections in women with obesity who have cesarean delivery. The multi-site study revealed using prophylactic negative pressure wound therapy (NPWT) does not appear to lower the risk of infection for this high-risk group.
