Chikungunya May Affect Central Nervous System As Well As Joints And Lungs
Publicado em 04 de novembro de 2020
Washington [US], November 5 (ANI): A study conducted by an international team of researchers with FAPESP's support shows that infection by chikungunya virus can produce even more severe manifestations than the typical symptoms of the disease, such as acute fever, headache, rash, and intense joint and muscle pain.
The analysis was performed by 38 researchers affiliated with the Federal University of Ceara (UFC), the University of Sao Paulo (USP), and the Ministry of Health in Brazil, and [...]

Brazilian researchers discover how muscle regenerates after exercise
Publicado em 28 outubro 2020Researchers at the University of São Paulo (USP) in Brazil have discovered that the muscle regeneration promoted by aerobic exercise is mediated by changes in oxygen consumption by satellite cells, also known as skeletal muscle stem cells. The discovery is expected to be used to help people recover from injury and combat the loss of muscle mass associated with aging. Previous research showed that weight lifting and other kinds of strength training increase the number of [...]ver notícia -
Word graph analysis confirms that dream report structure varies according to sleep stage
Publicado em 21 outubro 2020Some dreams are so vivid that they can be recalled as if they were movies, full of connections and with a beginning, middle and end. Others in contrast resemble WhatsApp GIFs, or at best a script for a video clip à la TikTok, often with powerful or meaningful images, but lacking that complex storylike structure. These analogies regarding different kinds of dream report or dream narrative were provided by Natalia Mota, a neuroscientist affiliated with the Federal University of Rio Grande [...]ver notícia -
Study describes COVID-19 transmission pattern
Publicado em 08 outubro 2020– The most widely used model to describe the epidemic evolution of a disease over time is called SIR, short for susceptible (S), infected (I), and removed (R). A susceptible person can be infected, and the infected person will eventually be removed owing to either immunization or death. The number of people in each class varies, whereas the total population, given by the sum of individuals in all three classes, is considered constant in the time scale of epidemic contamination. The [...]ver notícia -
Community health workers could play a key part in combating COVID-19 in Brazil, study says
Publicado em 06 outubro 2020Brazil has more than 286,000 community health workers integrated into the national primary healthcare program. These professionals form a broad network serving 75% of the population, especially low-income families who lack medical insurance and are the most adversely affected by the COVID-19 pandemic. "Back in March, researchers at Gabriela Lotta, a professor at Getúlio Vargas Foundation (FGV). Lotta is affiliated with the Center for Metropolitan Studies (CEM) , one of the [...]ver notícia -
Conservation planning in Amazon should prioritize aquatic biodiversity, study concludes
Publicado em 01 outubro 2020Science on October 2 suggests that prioritizing aquatic environments in conservation programs for the Amazon region can be up to six times more efficient than focusing on the protection of terrestrial species, as is usual. The conclusion is based on simulations using georeferenced field data on species diversity, weather and topography, among other things. The simulations enabled the researchers to identify the most important areas for the conservation of each group of species. When [...]ver notícia -
Venom glands similar to those of snakes are found for first time in amphibians
Publicado em 01 outubro 2020A group led by researchers at Butantan Institute in Brazil and supported by FAPESP has described for the first time the presence of venom glands in the mouth of an amphibian. The legless animal is a caecilian and lives underground. It has tooth-related glands that, when compressed during biting, release a secretion into its prey – earthworms, insect larvae, small amphibians and snakes, and even rodent pups. A paper reporting the study is published in iScience. “We were analyzing [...]ver notícia -
A study could provide guideline for exercise training aimed at high blood pressure patient
Publicado em 24 setembro 2020Researchers in the University of São Paulo's School of Physical Education and Sports (EEFE-USP) in Brazil compared the effect of two widely used classes of anti-hypertensive drugs on post-exercise hypotension, an expected and beneficial fall in blood pressure after a session of aerobic exercise, especially in the late afternoon or early evening. According to the researchers, the findings of their study can help health professionals choose the most beneficial time of day for patients [...]ver notícia -
Researchers discover a novel family of toxins used in bacterial competition
Publicado em 18 setembro 2020Toxic protein inhibits cell wall synthesis in rival bacteria. Discovery helps explain how pathogens cause imbalances in established microbial communities and could pave the way to the development of novel anti-microbial compounds. By André Julião | Agência FAPESP – Researchers at the University of São Paulo (USP) in Brazil have characterized a novel family of anti-bacterial toxins present in bacteria, including Salmonella enterica. This species uses toxic [...]ver notícia -
Exercise protocol mitigates one of the most incapacitating symptoms of Parkinson's disease
Publicado em 15 setembro 2020Freezing of gait, one of the most incapacitating symptoms of Parkinson’s disease, manifests as sudden, short episodes of an inability to move the feet forward despite the intention to walk. Researchers at the University of São Paulo (USP) in Brazil have shown that the disorder can be mitigated by means of a complex physical exercise protocol designed to stimulate different motor and cognitive skills simultaneously. An article on the study is published in the journal Movement [...]ver notícia
