DEPRIVATION among society at large is 'driving' Covid-19 disparities among minority ethnic groups - predominantly South Asian and Black African or Caribbean populations - and could be considered the main cause of disproportionate infection rates, hospitalisation and deaths experienced by these populations, according to new analysis from the University of Leicester.
Tokyo, Japan - Researchers from Tokyo Metropolitan University have shown that skeletal muscle satellite cells, key players in muscle repair, proliferate better in low glucose environments. This is contrary to conventional wisdom that says mammalian cells fare better when there is more sugar to fuel their activities. Because ultra-low glucose environments do not allow other cell types to proliferate, the team could produce pure cultures of satellite cells, potentially a significant boost for biomedical research.
The neurons in our nervous system "talk" to each other by sending and receiving chemical messages called neurotransmitters. This communication is facilitated by cell membrane proteins called receptors, which pick up neurotransmitters and relay them across cells. In a recent study published in Nature Communications, scientists from Japan report their findings on the dynamics of receptors, which can enable understanding of the processes of memory formation and learning.
Genome sequencing of thousands of SARS-CoV-2 samples shows that surges of COVID-19 cases are driven by the appearance of new coronavirus variants, according to new research from the School of Veterinary Medicine at the University of California, Davis published April 1 in Scientific Reports.
In some cancers, including leukemia in children and adolescents, obesity can negatively affect survival outcomes. Obese young people with leukemia are 50% more likely to relapse after treatment than their lean counterparts.
Hamilton, ON (April 1, 2021) - People living with the often-debilitating effects of Crohn's disease may finally gain some relief, thanks to ground-breaking research led by McMaster University.
McMaster investigator Brian Coombes said his team identified a strain of adherent-invasive E-coli (AIEC) that is strongly implicated in the condition and is often found in the intestines of people with Crohn's disease.
LA JOLLA--(April 1, 2021) Neurons lack the ability to replicate their DNA, so they're constantly working to repair damage to their genome. Now, a new study by Salk scientists finds that these repairs are not random, but instead focus on protecting certain genetic "hot spots" that appear to play a critical role in neural identity and function.
Chestnut Hill, MA (4/1/2021) - A gender gap in negotiation emerges as early as age eight, a finding that sheds new light on the wage gap women face in the workforce, according to new research from Boston College's Cooperation Lab, lead by Associate Professor of Psychology and Neuroscience Katherine McAuliffe.
Children and young adults who receive CAR T-cell therapy for the most common childhood cancer - acute lymphoblastic leukemia - suffer remarkably fewer relapses and are far more likely to survive when the treatment is paired with a subsequent stem cell transplant, a new study finds.
HKBU-led research reveals hyocholic acids are promising agents for diabetes prediction and treatment
A series of studies led by researchers from Hong Kong Baptist University (HKBU) have revealed that hyocholic acid and its derivatives (collectively known as HCAs), a component of bile acids that facilitate fat digestion, are a promising risk indicator of type 2 diabetes. The strong efficacy of HCAs in regulating blood glucose levels and protecting against diabetes has also been uncovered. The findings open a window for the development of HCA-based predictive markers as well as anti-diabetic drugs.
Autistic adults can be wrongly perceived as deceptive and lacking credibility, Flinders University researchers say, with this working against many caught in the legal system.
Ahead of World Autism Awareness Day (2 April 2021), a new paper in the Journal of Autism and Developmental Disorders asked 1,410 civilians to respond to video recordings with 30 adults with Autism Spectrum Disorder (ASD) and 29 non-ASD individuals to examine whether stereotypical behaviors associated with autism influenced people's perceptions of the individual.
The findings published in eLife show that men with this unstable subtype of the Y chromosome have a significantly increased risk of genomic rearrangements. These rearrangements affect the sperm production process (spermatogenesis) and consequently, these men can be up to nine times more likely to have fertility issues. Molecular diagnostics of this genetic variant could help identify those at higher risk in their early adulthood, giving them the chance to make decisions about future family planning early on.
Infants born by cesarean section have a relatively meager array of bacteria in the gut. But by the age of three to five years they are broadly in line with their peers. This is shown by a study that also shows that it takes a remarkably long time for the mature intestinal microbiota to get established.
Fredrik Bäckhed, Professor of Molecular Medicine at Sahlgrenska Academy, University of Gothenburg, has been heading this research. The study, conducted in collaboration with Halland County Hospital in Halmstad, is now published in the journal Cell Host & Microbe.
Although beef is one of the most consumed foods around the world, eating it when it's past its prime is not only unsavory, but also poses some serious health risks. Unfortunately, available methods to check for beef freshness have various disadvantages that keep them from being useful to the public. For example, chemical analysis or microbial population evaluations take too much time and require the skills of a professional. On the other hand, non-destructive approaches based on near-infrared spectroscopy require expensive and sophisticated equipment.
PROVIDENCE, R.I. [Brown University and Providence Veterans Affairs Medical Center] -- Brain-computer interfaces (BCIs) are an emerging assistive technology, enabling people with paralysis to type on computer screens or manipulate robotic prostheses just by thinking about moving their own bodies. For years, investigational BCIs used in clinical trials have required cables to connect the sensing array in the brain to computers that decode the signals and use them to drive external devices.
