COVID-19 patients who are overweight or obese are more likely to develop a more severe infection than patients of healthy weight, and they require oxygen and invasive mechanical ventilation more often. There is no increased risk of death . These conclusions, for which more than 7,000 patients were studied, appear from international research in eleven countries, including the Netherlands (Radboud university medical center).
Due to global warming, not only the temperatures in the atmosphere and in the ocean are rising, but also winds and ocean currents as well as the oxygen distribution in the ocean are changing. For example, the oxygen content in the ocean has decreased globally by about 2% in the last 60 years, particularly strong in the tropical oceans. However, these regions are characterized by a complex system of ocean currents. At the equator, one of the strongest currents, the Equatorial Undercurrent (EUC), transports water masses eastwards across the Atlantic.
WASHINGTON -- Researchers are blurring the lines between science and art by showing how a laser can be used to create artistic masterpieces in a way that mirrors classical paints and brushes. The new technique not only creates paint-like strokes of color on metal but also offers a way to change or erase colors.
A new study investigates a genetic culprit behind abdominal aortic aneurysm, a serious condition that puts people at risk of their aorta rupturing - a potentially deadly event.
Finding a viable genetic target for AAA could change the game, says senior author Katherine Gallagher, M.D., a vascular surgeon and an associate professor of surgery and microbiology and immunology at Michigan Medicine, the academic medical center of the University of Michigan.
INDIANAPOLIS -- A new report from the National Academies of Sciences, Engineering, and Medicine (National Academies) details the state of dementia care and research in America and provides guidance on future research to make sure both patients and their families are having their needs met by the care they receive. Sections of the report highlight the effectiveness of the collaborative care model as well as successful implementation, citing research from Regenstrief Institute, Eskenazi Health and the Indiana University School of Medicine.
JACKSONVILLE, Fla. -- In a new paper published in Nature Communications, Mayo Clinic researchers and collaborators report the protein-coding gene SERPINA5 may worsen tau protein tangles, which are characteristic of Alzheimer's disease, and advance disease. By combining clinical expertise, brain tissue samples, pathology expertise and artificial intelligence, the team clarified and validated the relevance of the gene to Alzheimer's disease.
Hydrogen will be needed in large quantities as an energy carrier and raw material in the energy system of the future. To achieve this, however, hydrogen must be produced in a climate-neutral way, for example through so-called photoelectrolysis, by using sunlight to split water into hydrogen and oxygen. As photoelectrodes, semiconducting materials are needed that convert sunlight into electricity and remain stable in water. Metal oxides are among the best candidates for stable and inexpensive photoelectrodes.
Eighteen minutes might be all it takes to ensure a full recovery for stroke patients in rural South Carolina.
By changing EMS workflows and incorporating telemedicine techniques, physicians at MUSC Health have partnered with Georgetown Memorial Hospital and Hampton Regional Medical Center to significantly shorten the time between a patient's stroke symptom onset and their treatment, as recently reported in the Journal of Stroke and Cerebrovascular Diseases.
April 19, 2021 - At the current rate of change, it will take more than 200 years for the proportion of women in orthopaedic surgery to reach parity with the overall medical profession, according to a study in Clinical Orthopaedics and Related Research® (CORR®), a publication of The Associ
The social science literature has long viewed homophily and network-based job recruitment as crucial drivers of segregation. Researchers at Linköping University and ESADE, Ramon Llull University now show that this view must be revised. In their Science Advances article, they call attention to a previously unidentified factor, the Trojan-horse mechanism, which shows that network-based recruitment can reduce rather than increase segregation levels.
Although antibodies induced by SARS-CoV-2 infection are largely protective, they do not completely protect against reinfection in young people, as evidenced through a longitudinal, prospective study of more than 3,000 young, healthy members of the US Marines Corps conducted by researchers at the Icahn School of Medicine at Mount Sinai and the Naval Medical Research Center, published April 15 in The Lancet Respiratory Medicine.
In recent years there has been an exhaustive study of red dwarf stars to find exoplanets in orbit around them. These stars have effective surface temperatures between 2400 and 3700 K (over 2000 degrees cooler than the Sun), and masses between 0.08 and 0.45 solar masses.
LA JOLLA, CALIF. - April 16, 2021 - Scientists at Sanford Burnham Prebys have identified a set of human genes that fight SARS-CoV-2 infection, the virus that causes COVID-19. Knowing which genes help control viral infection can greatly assist researchers' understanding of factors that affect disease severity and also suggest possible therapeutic options. The genes in question are related to interferons, the body's frontline virus fighters.
The study was published in the journal Molecular Cell.
Scientists have figured out how to modify CRISPR's basic architecture to extend its reach beyond the genome and into what's known as the epigenome -- proteins and small molecules that latch onto DNA and control when and where genes are switched on or off.
Look deep inside the brain of someone with Alzheimer's disease, most forms of dementia or the concussion-related syndrome known as chronic traumatic encephalopathy (CTE) and you'll find a common suspected culprit: stringy, hairball-like tangles of a protein called tau.
Such conditions, collectively known as "tauopathies" strike scores of people across the globe, with Alzheimer's alone affecting six million people in the United States.
But more than a century after German psychiatrist Alois Alzheimer discovered tau tangles, scientists still have much to learn about them.
