This is the conclusion of a study conducted at the University of São Paulo with 23 volunteers. The data show that only evening workouts regulated so-called baroreflex sensitivity – a mechanism that compensates for sudden changes in blood pressure.
A technique developed by researchers at São Paulo State University was tested in the Brazilian state of Mato Grosso and more accurately delineated areas of natural vegetation and agricultural production by crop type; the results showed 95% accuracy in mapping.
Application of iron sulfate in a degraded area of the Chapada dos Veadeiros National Park, in central Brazil, reduced nutrient availability and contained exotic species, allowing grasses typical of the Cerrado biome, adapted to poor soils, to regrow.
In rodent experiments, a cellulose product with silver nanoparticles was able to reduce microbial colonies in skin lesions, speeding up healing; treatment could benefit people with diabetic foot, burns, and bedridden patients with pressure ulcers.
In experiments conducted at the University of São Paulo, tumor stem cells became less able to proliferate and invade tissues when the production of the prion protein was blocked by gene editing; the results suggest that the molecule could be a therapeutic target.

Characteristics of social immune memory were observed in colonies of Atta sexdens exposed to four different pathogenic fungi. The insects increased their cleaning behavior one week and one month after initial contact, but not after 60 days.
The Federal University of São Carlos has developed a process that uses sugarcane molasses as a substrate in one of the stages of the chitosan production process. The polymer can also be used to control agricultural pests and to produce biofilms and drug-carrying capsules.
Detected in the state of Ceará, Brazil, the novel coronavirus has similarities with the coronavirus that causes Middle East respiratory syndrome, first identified in 2012. Experiments to find out whether it can infect humans are set to take place during 2025.
Study published in Nature reveals mechanism by which isoprene, a gas emitted by vegetation, produces large quantities of aerosols responsible for forming condensation nuclei; process may have an influence on global climate.
Researchers used an innovative approach and analyzed data from a large sample involving residents of four state capitals in different regions of Brazil; study contributes to preventive strategies for this type of tumor.
The method developed at the University of São Paulo detects and distinguishes between antibodies induced by the pathogens in blood samples. The strategy can be used to orient public policy in health and to evaluate the efficacy of dengue vaccines.
