A naturally occurring molecule could help to prevent – and even treat – influenza, according to a new study published in the journal Gut Microbes. The molecule, indole-3-propionic acid (IPA), occurs naturally in the gut of mammals and may play a protective role in the body’s response to infection. The findings were published by scientists at the State University of Campinas (UNICAMP) in São Paulo state, Brazil, working with a team at the Pasteur Institute in Lille, [...]

According to an article published in the journal Clinical Oral Investigations, people who suffer from post-traumatic stress disorder (PTSD) often report constant clenching or grinding of the teeth during the day, a condition known as awake (or diurnal) bruxism. Its prevalence in the general population varies from 8% to 30%. The study, which included clinical examination of 76 patients and controls, highlights the importance of collaboration by dentists and psychiatrists to diagnose both health [...]

Weight training can help reduce body fat and increase muscle strength and mass in older people, contributing to functional autonomy and avoidance of falls and injury. Furthermore, recent studies have shown that it can also benefit the mental health of older people, especially those who suffer from anxiety and depression. These benefits were confirmed by a study reported in the journal Psychiatry Research. The study involved a systematic review and meta-analysis of more than 200 articles on [...]

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 [...]

A study conducted at the University of São Paulo (USP) in Brazil and described in an article published in the journal Scientific Reports shows that anti-inflammatory drugs commonly taken by children may be associated with dental enamel defects (DEDs), currently seen in about 20% of children worldwide. The authors, who are affiliated with the Ribeirão Preto Dental School (FORP-USP) and School of Pharmaceutical Sciences (FCFRP-USP), investigated the effects of celecoxib and [...]

Strength training practiced with moderate to vigorous intensity two or three times a week is an effective way to mitigate arterial hypertension (high blood pressure), according to a Brazilian study described in an article published in the journal Scientific Reports. The mechanisms behind the lowering of blood pressure by aerobic exercise are well studied, but little research has been done on the effects of strength exercise on hypertension along similar lines to this review [...]

Bioengineered artificial skin has become an increasingly important and reliable platform for researchers to test the safety and efficacy of drugs and cosmetics. It can be produced on a large scale and is a good substitute for animal testing. The most promising technologies for production of in vitro models include 3D bioprinting. Because it is recent, however, its performance has yet to be sufficiently validated in comparison with traditional manually produced models. This was the main aim of a [...]

An article published in the journal eLife reports a study in which researchers concluded that the proportion of the population previously infected by SARS-CoV-2 (infection-induced seroprevalence) can be estimated using blood donation samples. The findings offer a sort of “portrait” of the first year of the COVID-19 epidemic in Brazil. According to the authors, their novel methodology can also be used to track and estimate collective immunity to other infectious [...]

Vitamin D plays an important role in the regulation of calcium and phosphorus absorption by the organism. It also helps keep the brain and immune system working. Researchers at the Federal University of São Carlos (UFSCar) in Brazil and University College London (UCL) in the United Kingdom have now shown that vitamin D supplementation reduces the risk of dynapenia in older people by 78%. Dynapenia is an age-associated loss of muscle strength. It can be partially explained by muscle [...]
