Lack of physical exercise during COVID-19 confinement may lead to a rise in mortality
Publicado em 19 janeiro 2021
In a review article published in Frontiers of Endocrinology, Brazilian researchers estimate a reduction of 35% in levels of physical activity and a rise of 28% in sedentary behavior in the initial months of confinement imposed by the pandemic
Social distancing and working from home help prevent transmission of the novel coronavirus but can be conducive to unhealthy behavior such as bingeing on fast food or spending more time in a chair or on a couch staring at a screen, and generally moving [...]

Study reveals structure of protein and permits search for drugs against neglected diseases
Publicado em 07 janeiro 2021Brazilian researchers have managed to decipher the structure of a protein found in parasites that cause neglected tropical diseases, paving the way to the development of novel medications. Thanks to the discovery it will be possible to seek more potent molecules capable of destroying the pathogens directly, with fewer adverse side-effects for patients. The study detailed the structural characteristics of the protein deoxyhypusine synthase (DHS), found in Brugia malayi, one of the [...]ver notícia -
Virtual Reality Applied to Rehabilitation for Stroke and Neurodegenerative Disease Patients
Publicado em 14 dezembro 2020A study performed at one of the Research Centers supported by FAPESP resulted in development of a novel rehabilitation device. The article was recognized as outstanding by the 20th International Conference on Computational Science and its Applications Virtual reality-based rehabilitation programs are becoming an important complement to conventional motor therapy for stroke patients and individuals with neurodegenerative diseases. Immersion in virtual environments stimulates several sensory [...]ver notícia -
Adipose tissue may be the source of inflammatory factors that aggravate COVID-19
Publicado em 20 novembro 2020There is growing evidence that adipose tissue plays a key role in the aggravation of COVID-19. One of the theories under investigation is that fat cells (adipocytes) act as a reservoir for SARS-CoV-2 and increase viral load in obese or overweight individuals. Scientists also suspect that during infection fat cells release into the bloodstream substances that boost the inflammatory reaction triggered by the virus in the organism. These hypotheses are being investigated by researchers at the [...]ver notícia -
Tube-dwelling anemone toxins have pharmacological potential, mapping study shows
Publicado em 29 outubro 2020Researchers based in Brazil and the United States have completed the first-ever mapping exercise to profile the toxins produced by tube-dwelling anemones, or cerianthids, a family of marine animals belonging to the same phylum (Cnidaria) as sea anemones, jellyfish and corals. The analysis revealed that the toxins that can act on the nervous system, cardiovascular system, and cell walls, among other functions, paving the way to the discovery of novel medications. “Tube anemones and sea [...]ver notícia -
Plastic film protects surfaces against novel coronavirus on contact
Publicado em 16 outubro 2020An adhesive plastic film designed to protect surfaces such as doorknobs, handrails, elevator buttons, and touch screens inactivates the novel coronavirus on contact. The manufacturer of the film is Promaflex. It has nanoparticles of silver and silica built into its polyethylene structure, thanks to technology developed by Nanox, a Brazilian company based on São Paulo and supported by São Paulo Research Foundation, through FAPESP’s Innovative Research in Small Business [...]ver notícia -
Obesity implies risk of COVID-19 regardless of age, sex, ethnicity and health condition
Publicado em 14 outubro 2020The probability that an obese person will develop severe COVID-19 is high regardless of age, sex, ethnicity, and the presence of co-morbidities such as diabetes, high blood pressure, and heart or lung disease, according to a study by Brazilian researchers published in Obesity Research & Clinical Practice. The systematic review and meta-analysis of relevant data in the scientific literature focus on nine clinical studies, which in aggregate reported the evolution of 6,577 COVID-19 patients [...]ver notícia -
Study describes COVID-19 transmission pattern
Publicado em 09 outubro 2020Model developed by Brazilian researchers predicts spatial and temporal evolution of epidemic diseases and can help plan more effective social isolation programs with less socio-economic impact. By José Tadeu Arantes | Agência FAPESP – 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 [...]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 Imperial College London noted Brazil’s network of community health workers as a valuable asset that could assure an effective response to the pandemic.

Exercise hormone may modulate genes associated with replication of novel coronavirus
Publicado em 22 setembro 2020A study conducted by researchers at São Paulo State University (UNESP) suggests that irisin, a hormone secreted from muscles in response to exercise, could have a therapeutic effect on COVID-19 patients. When they analyzed adipose cell gene expression, the researchers found that irisin modulated genes associated with replication of the novel coronavirus SARS-CoV-2 in human cells. This finding was based on analysis of the transcriptome (all RNAs produced by genes) of adipose cells not [...]ver notícia
