BIRMINGHAM, Ala. - Race associates with the risk of death from end-stage heart failure. So, identifying the molecular determinants of that risk may help the pursuit of the novel diagnosis and prognosis of heart failure, and its therapy.
More than 20 years after the discovery of the parkin gene linked to young-onset Parkinson's disease, researchers at The Ottawa Hospital and the University of Ottawa may have finally figured out how this mysterious gene protects the brain.
With a lethal, airborne virus spreading fast, hospitals had to change how they treated patients and policies for how caregivers provided that treatment. But for maternity patients and nurses some of those changes had negative outcomes, according to a new University of Washington study.
How many species of birds are there in the world? It depends on whose count you go by. The number could be as low as 10,000 or as high as 18,000. It's tough to standardize lists of species because the concept of a "species" itself is a little bit fuzzy.
A new analysis of lung epithelial cells from COVID-19 patients reveals how the protective complement branch of the immune system, which usually plays roles in both innate and adaptive immunity, can convert to a harmful system during COVID-19. Blocking excessive complement activity in lung epithelial cells with a combination of existing chemotherapy and antiviral medications - ruxolitinib and remdesivir, respectively - helped normalize the production of complement proteins by infected lung epithelial cells in human cell culture experiments, the researchers found.
WYOMISSING, Pa. -- Teaching people to become entrepreneurs requires more than just passing on entrepreneurial skills, according to a team of Penn State Berks-led researchers. Would-be entrepreneurs also need to understand -- and negotiate -- the barriers that they might face.
Eight months after mild COVID-19, one in ten people still has at least one moderate to severe symptom that is perceived as having a negative impact on their work, social or home life. The most common long-term symptoms are a loss of smell and taste and fatigue. This is according to a study published in the journal JAMA, conducted by researchers at Danderyd Hospital and Karolinska Institutet in Sweden.
The Mfd protein repairs bacterial DNA, but can also, to scientists' surprise, promote mutation.
Bacterial mutations can lead to antibiotic resistance.
Understanding this second "role" of the Mfd protein opens up opportunities for combating antibiotic resistance, and also the resistance of tumours to anti-cancer drugs and therapies.
A horse's gut microbiome communicates with its host by sending chemical signals to its cells, which has the effect of helping the horse to extend its energy output, finds a new study published in Frontiers in Molecular Biosciences. This exciting discovery paves the way for dietary supplements that could enhance equine athletic performance.
PISCATAWAY, NJ - Adolescents who frequently see billboard or storefront advertisements for recreational cannabis are more likely to use the drug weekly and to have symptoms of a cannabis use disorder, according to a new study in the Journal of Studies on Alcohol and Drugs.
Despite use being illegal for those below age 21 even in states that have approved recreational marijuana, "legalization may alter the ways that youth use cannabis," write the study authors, led by Pamela J. Trangenstein, Ph.D., M.P.H., of the University of North Carolina at Chapel Hill.
Study using electronic health records of 236,379 COVID-19 patients mostly from the USA estimates that one in three COVID-19 survivors (34%) were diagnosed with a neurological or psychiatric condition within six months of infection.
Anxiety (17%) and mood disorders (14%) were the most common. Neurological diagnoses such as stroke and dementia were rarer, but not uncommon in those who had been seriously ill during COVID-19 infection. For example, of those who had been admitted to intensive care, 7% had a stroke and almost 2% were diagnosed with dementia.
Philadelphia, April 7, 2021 - Building family child care home providers' (FCCH) self-efficacy--an individual's belief in their ability to manage their situation--for healthy eating is an important component of health promotion and can buffer the impact of stress on their diet quality, according to a new study in the Journal of Nutrition Education and Behavior, published by Elsevier.
A generation of talented but disadvantaged children are being denied access to higher education because academic success in lower and middle-income countries is continually 'protected by wealth', a study has found.
School-based interventions that target students with, or at risk of, academic difficulties in kindergarten to grade 6 have positive effects on reading and mathematics, according to an article published in Campbell Systematic Reviews.
The review analyzed evidence from 205 studies, 186 of which were randomized controlled trials, to examine the effects of targeted school-based interventions on students' performance on standardized tests in reading and math.
In addition to causing blood sugar imbalances, type 1 diabetes can contribute to nerve damage and sensory abnormalities--a condition call neuropathy--and has been linked to a higher risk of bone fractures. A new study published in the Journal of Bone and Mineral Research has examined the effects of type 1 diabetes and diabetic neuropathy on the skeleton.
