A team of South Korean researchers found that lactation can lower the incidence and reduce the risk of maternal postpartum diabetes. The researchers identified that lactation increases the mass and function of pancreatic beta cells through serotonin production. The team suggested that sustained improvements in pancreatic beta cells, which can last for years even after the cessation of lactation, improve mothers' metabolic health in addition to providing health benefits for infants.
A new strategy to trigger ferroptosis in target cancer cells using drug-metal coordination complexes
The fast-growing cancer incidence and mortality worldwide have raised great challenges for the currently available anticancer options, which warrants the development of new therapeutic modalities based on novel antitumor mechanisms. Ferroptosis, a recently discovered form of non-apoptotic cell death, is one such candidate and has already demonstrated immense potential in clinical oncology as it provides alternative therapeutic opportunities for the management of treatment-resistant tumors. In a research study published on Science Advances, lead author Prof.
New USC research reveals how APOE4, a genetic culprit for Alzheimer's disease, triggers leaks in the brain's plumbing system, allowing toxic substances to seep into the brain areas responsible for memory encoding and other cognitive functions.
The damage is linked to future problems in learning and memory, even when the disease's signature sticky plaques have not appeared. The findings suggest that the smallest blood vessels in the brain, which form the blood-brain barrier, might be a potential target for early treatment.
Neurobiologists at KU Leuven have discovered how the signalling molecule Neuromedin U plays a crucial role in our learning process. The protein allows the brain to recall negative memories and, as such, learn from the past. The findings of their study on roundworms have been published in the journal Nature Communications.
LOUISVILLE, Ky. - Several years ago, Guillermo Rougier, Ph.D., professor in the Department of Anatomical Sciences and Neurobiology at the University of Louisville, was approached by David Krause, Ph.D., curator at the Denver Museum of Nature & Science, to help identify a complete, 3-D fossil he had discovered on Madagascar.
"When Dr. Krause showed it to me in a scientific meeting and asked me for my opinion, I said I had never seen anything like this," Rougier recalled. "This mammal has teeth for which we have no parallel."
An international research team led by the University of Hong Kong (HKU) developed a new method to accurately track the spread of COVID-19 using population flow data, and establishing a new risk assessment model to identify high-risk locales of COVID-19 at an early stage, which serves as a valuable toolkit to public health experts and policy makers in implementing infectious disease control during new outbreaks. The study findings have been published in the journal Nature today (April 29).
CATONSVILLE, MD, April 29, 2020 - Job performance has long been understood to be the primary equalizing factor affecting promotions for men and women in the workplace, but research shows, women don't gain as much from the same performance improvements as men do. New research in the INFORMS journal Information Systems Research shows training plays an important part in promotions for women in the field of information technology.
TROY, N.Y. -- Women are underrepresented in leadership positions throughout the information technology industry. While more and more women are earning degrees in science, technology, engineering, and math -- or STEM -- fields, they don't necessarily pursue careers in IT, because they don't see opportunities for growth.
New research from the Lally School of Management at Rensselaer Polytechnic Institute published in Information Systems Research examines how gender affects the likelihood of promotions in the context of the IT industry.
Individuals with social anxiety disorder have markedly different personality traits than others. Emotional instability and introversion are hallmarks, according to a new study from Uppsala University published in PLOS ONE.
"Social anxiety disorder seems to be a problem that is strongly intertwined with personality, but at the same time it shows great variation," says Professor Tomas Furmark from the Department of Psychology at Uppsala University, who led the study.
SALT LAKE CITY - To replace aging and worn cells, the body primarily uses a process called mitosis, in which one cell divides into two. When a cell is ready to divide, it duplicates its DNA so a complete copy is available for each of the daughter cells. In this process, the DNA pieces, or chromosomes, must be precisely apportioned into the daughter cells. If one cell has an incomplete copy of the DNA or if the DNA becomes damaged, genetic disorders and diseases such as cancer can result.
(Boston)--In an effort to mitigate the spread of COVID-19 and to optimize allocation of healthcare resources, researchers are improving ways to treat patients with acute large vessel occlusion strokes in a safe manner that also better protects health care workers.
Researchers from Tilburg University in the Netherlands and the University of Cologne in Germany published a new paper in the Journal of Marketing that explains which factors influence media coverage of CSI events.
The study forthcoming in the Journal of Marketing is titled "When Does Corporate Social Irresponsibility Become News? Evidence from More than 1,000 Brand Transgressions Across Five Countries" and is authored by Samuel Stäbler and Marc Fischer.
Researchers at Baylor College of Medicine, the University of South Carolina and other institutions have identified tobacco smoking as a potential risk factor for infection of the COVID-19 virus.
Co-corresponding authors Dr. Christopher I. Amos, director of the Institute of Clinical and Translational Research at Baylor, Dr. Guoshuai Cai, assistant professor at the University of South Carolina, and their colleagues analyzed datasets of the RNA expressed by various types of lung tissue, comparing current and former smokers and non-smokers.
New Rochelle, NY, April 29, 2020--Researchers have reported a significant and positive relationship between the amount of virus present in a throat swab sample and the severity of COVID disease. The higher the relative viral load in the sample, the greater the organ damage, and the longer it would take for the viral RNA count to turn negative, according to the results published in Viral Immunology, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.
As the COVID-19 curve shows signs of flattening in the U.S. and elsewhere, public health officials are trying to grasp just how many people have been infected. Now, a proof-of-concept study in ACS' Analytical Chemistry describes a quick, sensitive test for antibodies against the coronavirus in human blood. The test could help doctors track a person's exposure to the disease, as well as confirm suspected COVID-19 cases that tested negative by other methods.
