In Jessica Barnes' palm is an ancient, coin-sized mosaic of glass, minerals and rocks as thick as a strand of wool fiber. It is a slice of Martian meteorite, known as Northwest Africa 7034 or Black Beauty, that was formed when a huge impact cemented together various pieces of Martian crust.
A first-of-its-kind trial has demonstrated that a receptor involved in the brain's reward system may be a viable target for treating anhedonia (or lack of pleasure), a key symptom of several mood and anxiety disorders. This innovative fast-fail trial was funded by the National Institute of Mental Health (NIMH), part of the National Institutes of Health, and the results of the trial are published in Nature Medicine.
Sometimes referred to as the "the Methuselah of freshwater fish", sturgeons and their close relatives are very old from an evolutionary point of view. Fossils indicate that sturgeons date back 250 million years and have changed very little during this period, at least as far as their external appearance is concerned. So it is not surprising that already Charles Darwin coined the term "living fossils" for them.
The research group "geriatric psychiatry in motion" of the German Sport University Cologne and the LVR-Hospital Cologne develop and evaluate exercise programmes for geriatric mental health care. Latest results from a study in acute dementia care indicate a special exercise programme is not only effective for the patients themselves, but also reduces the professional caregiver's burden caused by neuropsychiatric symptoms.
An artificial intelligence tool accurately predicted which patients newly infected with the COVID-19 virus would go on to develop severe respiratory disease, a new study found.
The work was led by NYU Grossman School of Medicine and the Courant Institute of Mathematical Sciences at New York University, in partnership with Wenzhou Central Hospital and Cangnan People's Hospital, both in Wenzhou, China.
Thousands more patients each year are surviving strokes, as the risk of death and disability after a stroke fell significantly between 2000 and 2015, according to analysis by Guy's and St Thomas' researchers.
The study, published in PLOS Medicine, looked at data from south London patients who had an ischaemic stroke - one caused by a blood clot - between 2000 and 2015. The team attribute the reduced risk to improvements in care and medication.
MEDFORD/SOMERVILLE, Mass. (March 30, 2020)--Researchers led by biomedical engineers at Tufts University invented a microfluidic chip containing cardiac cells that is capable of mimicking hypoxic conditions following a heart attack - specifically when an artery is blocked in the heart and then unblocked after treatment.
Patients with worsening heart failure and reduced ejection fraction who received the investigational drug vericiguat had a significantly lower rate of cardiovascular death or heart failure hospitalization compared with those receiving a placebo, based on research presented at the American College of Cardiology's Annual Scientific Session Together with World Congress of Cardiology (ACC.20/WCC).
(Philadelphia, PA) - Overuse injuries - think muscle strains, tennis elbow, and rotator cuff tears - are a considerable problem in the United States, especially among young athletes. But while commonly associated with sports, overuse injuries - particularly those involving muscle strains - also affect significant numbers of workers whose jobs involve manual labor.
Mount Sinai researchers have discovered a pathway that regulates special immune system cells in lung cancer tumors, suppressing them and allowing tumors to grow. The scientists also figured out how to interrupt this pathway and ramp up the immune system to prevent tumor formation or growth, offering a potential boost to immunotherapy, according to a study published in Nature in March.
Doctors and nurses in emergency departments at four academic centers and four community hospitals in the Northeast reported a wide range of emotions triggered by patients, hospital resources and societal factors, according to a qualitative study led by a University of Massachusetts Amherst social psychologist.
Washington, DC - March 27, 2020 - As we enter the second quarter of the COVID-19 pandemic, with testing for SARS-CoV-2 increasingly available (though still limited and slow in some areas), clinicians and public health officials are faced with new questions and challenges regarding testing for this novel virus. Since SARS-CoV-2 is a new virus, there is little evidence to fall back on for test utilization and diagnostic stewardship.
Women who suffer from psychiatric disorders such as depression, anxiety, mania and schizophrenia following the live birth of their first child are less likely to go on to have more children, according to the first study to investigate this in a large nationwide population.
Women undergoing radiotherapy for many cancers are more likely than men to be cured, but the side effects are more brutal, according to one of Australia's most experienced radiation oncology medical physicists.
University of South Australia (UniSA) Professor of Medical Radiation, Eva Bezak, says women are generally more sensitive to radiation than men, but this is not considered in international guidelines for radiation dosages.
Current guidelines are generally based on a person's height, weight or BMI, and radiobiological responses of the general population.
WASHINGTON--Patients with poorly controlled type 2 diabetes who underwent a novel, minimally invasive, endoscopic procedure called Revita® duodenal mucosal resurfacing (DMR) had significantly improved blood glucose (sugar) levels, liver insulin sensitivity, and other metabolic measures three months later, according to new data from the REVITA-2 study. These results, from a mixed meal tolerance test, have helped researchers verify the insulin sensitizing mechanism by which hydrothermal ablation of the duodenum improves blood sugar in patients with type 2 diabetes.
