Consumption of soluble dietary fiber favors renewal of intestinal epithelial cells, study shows
Publicado em 24 de julho de 2023
A high-fiber diet is known to have several health benefits. Scientific studies point to protection against such diseases as cancer and diabetes. However, exactly how fiber interacts with the intestines and the microorganisms that colonize them—the gut microbiota—is poorly understood.
A study conducted by Brazilian researchers and reported in an article published in the journal Microbiome shows that a diet containing suitable amounts of inulin, a soluble fiber abundant in chicory [...]

Study suggests resistance training can prevent or delay Alzheimer’s disease
Publicado em 03 julho 2023Regular physical exercise, such as resistance training, can prevent Alzheimer’s disease, or at least delay the appearance of symptoms, and serves as a simple and affordable therapy for Alzheimer’s patients. This is the conclusion of an article published in Frontiers in Neuroscience by Brazilian researchers affiliated with the Federal University of São Paulo (UNIFESP) and the University of São Paulo (USP). Although older people and dementia patients are unlikely to [...]ver notícia -
In resistance training, focusing on load or number of repetitions leads to same muscle growth
Publicado em 24 maio 2023Which kind of resistance training promotes more muscle growth: low load with many repetitions or high load with fewer repetitions? According to a study conducted at the State University of Campinas (UNICAMP) in São Paulo state, Brazil, it makes no difference. The study lasted eight weeks and involved 18 volunteers in two different training protocols. One group performed high-load (HL) exercises with fewer repetitions, while the other did low-load (LL) exercises with more repetitions. [...]ver notícia -
Yeast used in production of cachaça can prevent asthma, study shows
Publicado em 22 fevereiro 2023A daily dose of a strain of brewer’s yeast used to produce cachaça (distilled spirit made from fermented sugarcane juice) can act as a preventive against asthma, according to a Brazilian study involving male mice. The results are reported in an article published in the journal Probiotics and Antimicrobial Proteins. The authors are researchers at the University of São Paulo (USP) and the Federal University of Minas Gerais (UFMG). The yeast strain used in the study was [...]ver notícia -
Protein with anti-aging action combats inflammation and avoids death of neurons
Publicado em 01 fevereiro 2023The process of cellular aging is multifactorial, and its investigation involves several knowledge areas. Finding ways to protect cells against damage is a key focus. A group of researchers recently achieved noteworthy progress in this regard, as evidenced by an article published in Scientific Reports, a Springer Nature journal. According to the authors, in their study, the protein klotho protected glial cells against inflammation and death. Glia are non-neuronal cells of the brain and nervous [...]ver notícia -
Anti-inflammatory drugs commonly taken by children can cause alterations to dental enamel, study shows
Publicado em 20 dezembro 2022A 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 [...]ver notícia -
Vitamin D deficiency increases risk of losing muscle strength by 78%
Publicado em 13 dezembro 2022Vitamin 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 [...]ver notícia -
Study shows that amino acid taurine could be used in anti-aging therapy
Publicado em 23 julho 2022When our cells process the oxygen we breathe and the food we eat every day in order to survive, they generate potentially toxic by-products popularly known as “free radicals”. Some of these molecules perform functions essential to the organism, but if there are too many of them the cells’ internal structures can be damaged, preventing the cells from functioning properly and potentially leading to chronic disease. This process is called oxidative stress. Our bodies contain a [...]ver notícia -
8% of people infected by SARS-CoV-2 may be able to transmit the virus for more than two months, without necessarily manifesting any symptoms
Publicado em 27 janeiro 20228% of people infected by SARS-CoV-2 may be able to transmit the virus for more than two months, without necessarily manifesting any symptoms In a 38-year-old man who manifested mild symptoms of COVID-19 for 20 days, the novel coronavirus continued to be detected in his organism and to undergo mutations for 232 days. If he had not been given continuous medical care, maintained social distancing and worn a mask, he could have spread the virus throughout these seven months. The atypical case [...]ver notícia -
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
