Trials performed by researchers at the University of São Paulo with healthy young adults show that the right level of protein intake is the key to muscle health, regardless of protein source.

This is the main finding of a study published in Clinical Infectious Diseases. The authors analyzed blood samples collected in a town in the Brazilian Amazon before and after the first wave of the pandemic to detect the presence of antibodies against dengue virus and SARS-CoV-2.

Brazilian scientists conducted preclinical trials to test membranes produced from mesenchymal stem cells that can differentiate to cartilage and promote local immunoregulation.

Whole mitochondrial DNA sequencing of the three extant species of the aquatic mammal shows that they first split from their common ancestor after geological events isolated the South American region from the sea. The African species may have originated in migration borne by marine currents.

A review article by Brazilian researchers shows that alterations in the defense cell metabolism may explain why many patients who survive sepsis die within a year or suffer from long-term complications

Conclusion was drawn from a study that involved 92 adolescents aged 11-18. The findings underscore the importance of considering differences between the sexes when treatment is planned.

A study by scientists at a FAPESP-supported research center analyzed genetic material from 86 couples in which only one spouse was infected. The results suggest that more frequent variants in the resistant spouses could lead to more efficient activation of natural killer (NK) cells, which are part of the innate immune system, the first barrier against infection.

The research group created a virus capable of acting on specific adult brain regions, helping to elucidate the role of key neurons in the prefrontal cortex. They tested the technique on mice.

In an article published in PLOS ONE, scientists at a FAPESP-supported research center describe the impact of hypoproteinemia on the expression of microRNAs associated with kidney development in rat embryos.

Brazilian researchers show that feed supplementation improves fatty acid profile of milk and promotes a healthier omega-6/omega-3 ratio.

A mutation in the variant’s spike protein is associated with glycosylation, which prevents antibodies from binding strongly to the virus. If the discovery is confirmed by further research, it could serve as a basis for future vaccines that are more effective against novel variants.

According to researchers affiliated with the University of São Paulo, these indicators can orient preventive care for the most vulnerable and rehabilitation for survivors who suffer from long-term complications.

Researchers at the University of Campinas in Brazil reveal the mechanisms whereby SARS-CoV-2 disrupts the regulation of inflammation, coagulation and blood pressure when it infects alveolar cells, responsible for gas exchange in the lungs.

Researchers analyzed the effects of wildfires on plant cover and soil quality in the last 40 years. The findings of the study show that the forest is highly vulnerable even in well-conserved areas far from the ‘deforestation arc’.

People with diseases such as rheumatoid arthritis and lupus are more likely to have heart attacks, angina, and strokes. A review of the scientific literature on the subject shows that regular exercise improves vascular function in these patients.

Inexpensive test is non-invasive and based on detection of bladder cancer biomarkers in urine.

Sample collection is much easier and less invasive. Self-collecting is feasible, depending on the child’s age. Schools should reopen only with mass testing to keep track of asymptomatic cases, the researchers argue.

A multinational research group used data from São Paulo to perform calculations which suggest that even a minor reduction in the city’s mobility – equivalent to a rise from 45% to 50% in the social distancing index – correlates with a considerable fall in new infections and deaths after a few days.

A simple and affordable solution developed by researchers at the University of São Paulo and a Nigerian collaborator eliminates even multi-resistant bacteria. Clay, papaya seeds and banana peel are among the raw materials used by the group.

Butterflies are considered a key biological indicator of trends in the biome. The study quantified the contributions of landscape and climate variables to current species distribution patterns.

Resonant-tunneling diodes are used in high-frequency oscillators, wave emitters and detectors, logic gates, photodetectors, and optoelectronic circuits. The study was a collaboration between Brazilian and German researchers.

A clinical trial was conducted by researchers at the University of São Paulo with 240 patients who were given 200,000 IU of vitamin D3 on admission to hospital. The supplementation did not reduce length of stay or affect the proportion requiring intensive care.

Machines designed and prototyped by Setup Automação with PIPE-FAPESP’s support could come to market costing 25% less than currently available devices.

Infection of periodontal tissue, not just airways, explains the high viral load found in the saliva of COVID-19 patients, this study suggests.

An electrical impedance tomography system developed by a Brazilian company enabled critical care staff at a hospital run by Harvard University to adopt individualized mechanical ventilation strategies and reduced the need for extracorporeal membrane oxygenation (ECMO) therapy

A study by researchers at São Paulo State University reinforces the idea that environmental and climate-related changes resulting from the Andean uplift triggered a revolution in the caste system of these paper wasps.

A total of BRL 18.5 million will be allocated to funding for collaborative projects by researchers in the state of São Paulo with colleagues in other countries. Proposals must be submitted not later than July 10.

Researchers analyzed almost 30,000 RT-PCR tests on swabs from 4,269 players in 2020: 11.7% turned out positive. The rate was the same as among front-line health workers.

The researchers concluded that water stress, soil fertility and human-induced forest degradation cause gaps in the world’s largest tropical forest.

Researchers conducted the first large-scale survey of the microbiota present in the seamount’s ferromanganese crusts, describing bacteria and archaea involved in the nutrient cycle and formation of metals. Brazil has mineral exploration rights to the Rise, but mining there will have a major environmental impact.
