Lonely, older adults are nearly twice as likely to use opioids to ease pain and two-and-a-half times more likely to use sedatives and anti-anxiety medications, putting themselves at risk for drug dependency, impaired attention, falls and other accidents, and further cognitive impairment, according to a study by researchers at UC San Francisco. The study found that just over half of 6,000 respondents in a nationally representative survey of seniors living independently were not lonely, while 40 percent were moderately lonely, and 7 percent were highly lonely. The proportion of seniors ...

Researchers from the Institute of Process Engineering (IPE) of the Chinese Academy of Sciences, Beijing Chaoyang Hospital and the University of Queensland have developed a new formulation based on regulatory T-cell exosomes (rEXS) to deliver vascular endothelial growth factor (VEGF) antibodies for choroidal neovascularization therapy. The study was published in Nature Biomedical Engineering on July 26. Ocular neovascularization is often associated with age-related macular degeneration, diabetic retinopathy and other ocular diseases, which can cause severe vision loss. The present treatment for ocular neovascular disease in clinic is intravitreal injection of VEGF antibodies (aV) to block the activity of VEGF ...

BOSTON - In a multi-hospital analysis of individuals who experienced an allergic reaction to their first mRNA COVID-19 vaccine dose, all patients who went on to receive a second dose tolerated it without complications. The research, which was led by allergists at Massachusetts General Hospital (MGH) and is published in JAMA Internal Medicine, indicates that a first dose reaction to COVID-19 vaccination should not keep people from getting a second dose. Allergic reactions after mRNA COVID-19 vaccinations have been reported to be as high as 2%, with anaphylaxis--a life-threatening whole-body allergic reaction--occurring in up to 2.5 per 10,000 people. ...

Plants, including crops such as rice and wheat, obtain their essential mineral nutrients and water through their roots, making them an important interface between plants and the soil environment. The roots of land plants associate with a wide range of microbes - including bacteria - that are recruited from the surrounding soil and assemble into structured communities known as the root microbiota. These microbial communities are sustained by the plant host, which provides them with nutrients, primarily in the form of organic carbon compounds secreted by the root. In turn, these commensal bacteria mediate multiple processes ...

New York, NY (July 26, 2021) - Researchers have identified a rare class of genetic differences transmitted from parents without autism to their affected children with autism and determined that they are most prominent in "multiplex" families with more than one family member on the spectrum. These findings are reported in Recent ultra-rare inherited variants implicate new autism candidate risk genes, END ...

Bethesda, MD (July 26, 2021) -- There is an urgent need to develop and implement effective screening, diagnosis and treatment strategies for patients with nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH), common liver conditions with a rising burden in the U.S. and globally. This is particularly important for the most at-risk patients, those with diabetes and obesity. As a critical first step, the American Gastroenterological Association (AGA) -- in collaboration with seven professional associations -- convened an international conference of 32 experts to develop a multidisciplinary action plan to improve care for the growing population of patients with NAFLD ...

How do you study a group of organisms with over 300,000 species, dispersed across all seven continents, and with up to 50 times as much DNA content as the human genome? This is the question posed to biologists studying the evolutionary history of flowering plants, called angiosperms, whose rapid diversification was so convoluted a problem that Darwin referred to it as the 'abominable mystery.' This month, both the American Journal of Botany (AJB) and Applications in Plant Sciences (APPS) are devoting their July issues to what has recently become a turning point in the way scientists study the relationships among flowering plants. Dubbed Angiosperms353, the initiative combines ...
