Washington DC [US], August 30 (ANI): A review paper published in the journal Foods describes a study that provides an overview of studies on minimally processed vegetables (MPVs), with a particular focus on the Brazilian market. Data is presented on hygiene indicators and pathogenic microorganisms, especially Escherichia coli (the main indicator of fecal contamination), Salmonella spp., and Listeria monocytogenes, with prevalence rates ranging from 0.7 per cent to 100 per cent, 0.6 per cent [...]

Research conducted at the University of São Paulo (USP) in Brazil shows that SARS-CoV-2, the virus that causes COVID-19, can infect liver cells (hepatocytes), stimulating glucose production and leading to a condition similar to diabetes (hyperglycemia) in hospitalized patients, even if their blood sugar level was normal before they were admitted to hospital. An article on the study is published in Proceedings of the National Academy of Sciences (PNAS). The findings describe part of [...]

Since the start of the COVID-19 pandemic, a class of corticosteroids called glucocorticoids (GCs) have become established as one of the main treatment options, especially for severe cases, thanks to their anti-inflammatory and immunosuppressant action. Brazilian researchers recently discovered new ways in which these drugs influence the organism’s inflammatory response during an infection: they raise levels of endocannabinoids (eCBs), molecules produced by the organism itself and that [...]

Researchers at the University of São Paulo (USP) in Brazil have created an exercise training program that survivors of severe COVID-19 can safely perform at home as rehabilitation therapy for persistent symptoms after they are discharged from hospital. Findings of a study recently reported in the British Journal of Sports Medicine show that exercise can improve the quality of life for these patients, benefitting their health and functionality while reducing the number of persistent [...]

A research model of dietary intake in 184 countries, developed by researchers at the Friedman School of Nutrition Science and Policy at Tufts University, estimates that poor diet contributed to over 14.1 million cases of type 2 diabetes in 2018, representing over 70% of new diagnoses globally. The analysis, which looked at data from 1990 and 2018, provides valuable insight into which dietary factors are driving type 2 diabetes burden by world region. The study was published April 17 in the [...]

– Physical exercise practiced by patients submitted to bariatric surgery acts on brain regions involved in food intake, reducing hunger or accelerating satiety, for example. This was the result observed in a clinical trial conducted at Hospital das Clínicas (HC), the hospital complex run by the University of São Paulo’s Medical School (FM-USP) in Brazil. An article on the study, pointing to positive effects of exercise on obesity-related conditions in post-bariatric [...]

Newswise — Pain afflicts at least 1.5 billion people worldwide, and despite the availability of various painkilling drugs, not all forms of pain are treatable. Moreover, pain medications can have side-effects such as dependence and tolerance, especially in the case of morphine and other opioids.  In search of novel painkillers, researchers at Butantan Institute’s Special Pain and Signaling Laboratory (LEDS) in São Paulo, Brazil, studied TRPV1, a sensory neuron [...]

People with long COVID who experience anxiety and depression months after a mild case of COVID-19 may have brain changes that affect the function and structure of the brain, according to a preliminary study released today, February 20, 2023, that will be presented at the American Academy of Neurology’s 75 th Annual Meeting being held in person in Boston and live online from April 22-27, 2023. “There is still much to learn about long COVID, which includes a wide range of health [...]

Proven to protect against a wide array of diseases, exercise may be the most powerful anti-aging intervention known to science. However, while physical activity can improve health during aging, its beneficial effects inevitably decline. The cellular mechanisms underlying the relationship among exercise, fitness and aging remain poorly understood. In a paper published in the Proceedings of the National Academy of Sciences, researchers at Joslin Diabetes Center investigated the role of one [...]
