Infertility is a problem that affects between 8% and 12% of couples of reproductive age worldwide – for some of them, the problem interrupts a life project, which is the desire to have children and build a family. Advances in technology and medicine have made assisted reproductive treatments possible, but they can be physically and psychologically draining for the couples involved, especially because of expectations of results that may not be achieved. The emotional impact of [...]

Working out and taking omega-3s may quietly heal your mouth from within. The combination helps the immune system reduce inflammation and protect teeth from bone loss. Exercise and omega-3s unite to keep your smile strong and inflammation low. Source: Fundação de Amparo à Pesquisa do Estado de São Paulo Summary: Researchers found that combining regular exercise with omega-3 supplements can make a big difference for oral health. The duo helps the immune system fight off chronic [...]

Studies conducted in mice have shown that the COVID-19 vaccine being developed by researchers at the University of São Paulo's Medical School (FM-USP) in Brazil is safe and efficacious. The vaccine triggered a satisfactory immune response against the pathogen in the mice and protected them from infection. An article describing the results is published in the journal Scientific Reports. "Most vaccines are based on attenuated or inactivated viruses, but our next-generation [...]

An international team of researchers has completed the most comprehensive survey ever of the predicted planetwide effects of drought and global warming on anurans (frogs and toads). An article reporting their findings is published in the journal Nature Climate Change. "The Amazon and the Atlantic Rainforest are the biomes with the most anuran species and the highest probability of an increase in both the frequency and intensity or duration of drought events. This will be [...]

A compound derived from Nectandra leucantha, a tree native to southern Brazil (local names canela-seca or canela-branca), has the potential to be used to treat visceral leishmaniasis, a neglected tropical disease associated with poverty, malnutrition, poor housing and lack of basic sanitation.  The disease is almost always fatal if left untreated. Most cases occur in Brazil, East Africa and India, according to the World Health Organization (WHO). An estimated [...]

Brazilian researchers have introduced a thought-provoking perspective on a long-standing debate among physicists: how many fundamental constants are required to describe the universe? Their conclusion - just one, the "second" - could simplify how we understand physical measurements. The study, published in Scientific Reports, was conducted by George Matsas and Vicente Pleitez from Sao Paulo State University (IFT-UNESP), Alberto Saa from the State University of Campinas [...]

A group of Brazilian researchers has presented an innovative proposal to resolve a decades-old debate among theoretical physicists: how many fundamental constants are needed to describe the observable universe? Here, the term "fundamental constants" refers to the basic standards needed to measure everything. The study, published in the journal Scientific Reports, involved George Matsas and Vicente Pleitez , both from the Institute of Theoretical [...]

Postprandial hypoglycemia is one of the main complications of bariatric surgery and can affect up to 30% of patients. Unlike ordinary hypoglycemia, in which low blood sugar is usually associated with little food, postprandial hypoglycemia occurs after meals and causes symptoms such as sweating, tremors, weakness and even mental confusion. A study conducted at Harvard University in the United States has identified the central role of serotonin (a hormone involved in mood regulation) in the [...]

Pancreatic cancer has recently been included in the list of diseases about which Brazil's National Cancer Institute (INCA) periodically publishes statistics. Although it is not the most frequent type of cancer, its high lethality makes it one of the leading causes of death from cancer in Brazil, partly owing to late diagnosis. It's striking how little data on the disease is available in Brazil and indeed in Latin America as a whole. There are no studies on pancreatic cancer involving [...]
