Study helps understand why obesity increases risk of cardiovascular complications in COVID-19
Publicado em 12 novembro 2021
In COVID-19 patients, obesity is the factor most associated with the development of endothelial dysfunction, a condition in which the blood vessels become unable to contract and relax adequately, increasing the risk of events such as heart attacks, thrombosis (blood clotting), and stroke.
Endothelium refers to the thin sheet of cells lining the walls of arteries and veins, as well as the inside of the heart. Endothelial cells release substances that control vascular relaxation and contraction, [...]

Highly abundant virus in humans could be a biomarker for COVID-19
Publicado em 05 novembro 2021Torquetenovirus (TTV) is one of the viruses most frequently found in the human organism. It is also common in monkeys and domestic animals. Its presence has not been associated with any known disease, but its excessive replication is a sign that something is wrong with the immune system. The correlation between high TTV load and immunosuppression has been used in medicine in certain contexts, such as monitoring transplant patients who take medication to prevent rejection of the transplanted [...]ver notícia -
Study points to remotely-supervised exercise classes as best option during lockdown
Publicado em 22 julho 2021Researchers at the University of São Paulo (USP) in Brazil investigated the effects of regular exercise on the physical and mental health of 344 volunteers during the pandemic. The study compared the effectiveness of three techniques: sessions led in person by a fitness instructor, sessions featuring an online instructor but no supervision, and sessions supervised remotely by an instructor via video call. The two kinds of session with professional supervision had the strongest effects [...]ver notícia -
Study innovates in gluten-free formulations, creating more palatable and nutritious bread
Publicado em 20 julho 2021A pregnant woman infected by Zika virus does not face a greater risk of giving birth to a baby with microcephaly if she has previously been exposed to dengue virus, according to a Brazilian study that compared data for pregnant women in Rio de Janeiro and Manaus. A Zika epidemic broke out in Brazil in 2015-16 in areas where dengue is endemic. Both viruses are transmitted by the mosquito Aedes aegypti. Some of the states affected by the Zika epidemic reported a rise in cases of microcephaly, a [...]ver notícia -
Novel coronavirus infects and replicates in salivary gland cells
Publicado em 07 julho 2021In Brazil, researchers at the University of São Paulo's Medical School (FM-USP) have discovered that SARS-CoV-2 infects and replicates in the salivary glands. Analysis of samples from three types of salivary gland obtained during a minimally invasive autopsy procedure performed on patients who died from complications of COVID-19 at Hospital das Clínicas, FM-USP's hospital complex, showed that tissues specializing in producing and secreting saliva serve as reservoirs for [...]ver notícia -
Direct action of SARS-CoV-2 on organs may lead to exacerbated inflammatory response in pediatric patients
Publicado em 01 junho 2021Besides common symptoms such as fever, cough and respiratory distress, some children have an atypical form of COVID-19 known as multisystem inflammatory syndrome in children (MIS-C), characterized by persistent fever and inflammation of several organs, such as the heart and intestines, as well as the lungs to a lesser extent. Reports of MIS-C have been increasingly associated with severe cases and deaths in several countries including Brazil since the onset of the pandemic. Researchers [...]ver notícia -
Cognitive-behavioral approach to treatment of obesity yields significant results
Publicado em 20 maio 2021Quality of life relating to physical and mental health can be a key element in the treatment of obese adults. For this reason, interdisciplinary clinical measures including cognitive and behavioral therapy may produce more significant outcomes for these people, reducing not just weight but also symptoms of depression. This is the main conclusion of a study conducted in Brazil by the Obesity Research Group at the Federal University of São Paulo (UNIFESP) in Santos, São Paulo [...]ver notícia -
Scientists use genetic engineering to explore mechanisms involved in psychiatric disorders
Publicado em 12 maio 2021Researchers used genetic engineering tools to create a virus that can enter specific neurons and insert into the prefrontal cortex a new genetic code that induces the production of modified proteins. In tests with mice, the alteration of these proteins was sufficient to modify brain activity, indicating a potential biomarker for the diagnosis of psychiatric disorders such as schizophrenia and autism. Sometimes referred to as the "executive brain," the prefrontal cortex is the region [...]ver notícia -
Bacteria that cause periodontitis are transmitted from parents to children
Publicado em 15 abril 2021Adults with periodontitis transmit micro organism that may trigger the illness in future to their kids, and the micro organism stay within the oral cavity even when the kids endure therapy of varied varieties, reinforcing the necessity for preventive care within the first 12 months of a child’s life. That is the primary conclusion of a research carried out on the College of Campinas (UNICAMP) within the state of São Paulo, Brazil. An article on the research is published in [...]ver notícia -
Why it is harder for Brazilians of African descent to find bone marrow donors
Publicado em 02 fevereiro 2021According to a study published in Frontiers in Immunology, the reason is their genetic heterogeneity and lack of proportional representation in the Brazilian bone marrow bank. Credit: Diogo Meyer A paper by a multidisciplinary team of scientists affiliated with various Brazilian institutions, including the University of São Paulo (USP) and the National Cancer Institute (INCA), shows that people of African descent are less likely to find a donor in the National Register of Voluntary Bone [...]ver notícia
