Research findings open the door to new strategies for promoting muscle function during aging
Publicado em 05 janeiro 2023
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 [...]

COVID-19 epidemiology can be estimated using blood donation samples
Publicado em 21 dezembro 2022An 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 [...]ver notícia -
Brazilian model for COVID-19 vaccination reduced severe cases and mortality even from variants
Publicado em 21 dezembro 2022A study conducted in Serrana, a small town in São Paulo state used as a model for COVID-19 vaccination in Brazil, shows that mass vaccination reduced the severe case and death rates even while the gamma and delta variants were circulating. Gamma and delta were considered alarming because they spread so much faster than previous variants. Based on an analysis of the virus’s evolutionary history (phylogeny), the researchers showed that the dynamics of SARS-CoV-2 substitution in [...]ver notícia
