Lung tissue samples from 47 people who died as a result of severe acute respiratory distress syndrome caused by the novel coronavirus were analyzed by Brazilian researchers. The findings can be used to improve treatment of the disease.
Loss of ACE2, the protein used by the novel coronavirus to invade human cells, leads to an imbalance in systems that regulate essential metabolic functions, impairing blood filtration and causing kidney injuries that can become permanent.
In an online seminar held by FAPESP, experts stressed that deforestation favors pathogen spillover from wild animals to humans, and that zoonotic disease surveillance urgently needs to be upgraded.
A study by Brazilian researchers evidenced a correlation between post-zika neurological complications and high levels of Gas6, a protein that facilitates viral replication. The findings are published in Brain, Behavior, and Immunity.
Molecules that attack cells and tissues in the patient’s own organism were detected in blood serum from volunteers infected by SARS-CoV-2, who progressed to moderate or severe COVID-19 after the samples were collected. The discovery could lead to novel therapeutic approaches.
Electric eels of the species Electrophorus varii feed on other fish, especially those habitually hunted by larger predators such as caimans and giant river otters. Hunting tactics enable them to maintain the same diet in the wet and dry seasons alike.
Study led by researchers at the University of São Paulo analyzed data for the period 1991-2014 and revealed that deforestation increased in election years. The phenomenon could cancel out the environmental gains achieved by conservation policies and actions, the scientists warn.
The use of a hypertonic solution of sodium chloride at 1.1% reduced viral replication by 88% in tests involving infected lung cells conducted by researchers at the University of São Paulo. If found efficacious in clinical trials, the strategy could contribute to the development of novel prophylactic interventions and therapies for COVID-19.
Brazilian scientists have developed an innovation that can be used in sensors to monitor brain function with even greater sensitivity than existing devices.
Participants in a webinar held by FAPESP pointed to disorganization of the research ecosystem, lack of government planning and underinvestment as obstacles to drug development in Brazil.
In older people, the probability of falling was reduced by a factor of 7 in a study conducted at the University of São Paulo. Constant use of rigid or reinforced footwear is the main enemy of healthy feet, according to the researchers.
To achieve a deeper understanding of the links between the nervous and immune systems, researchers at the Federal University of São Paulo inhibited the REM stage of sleep in mice to see how this affected the progress of infectious diseases, allergic processes and cancer treatment.
For the first time in Brazil, the RNA of SARS-CoV-2 has been directly sequenced by researchers at the Federal University of São Paulo, who studied the biochemical changes that determine the pathogen’s biology and how it is evolving.
Technology developed by a startup with FAPESP’s support dispenses with manual inspection, diagnosing problems rapidly and accurately, facilitating preventive maintenance, and cutting costs.
The fungus induces a hormone imbalance in the plant, leading to excessive growth of infected tissue and siphoning off the energy that should be used for fruit and root growth, according to an article by researchers at the University of São Paulo in New Phytologist.
One of the most promising fields is photovoltaics. Prototype perovskite solar cells have been shown to be more efficient than commercial silicon-based cells.
Researchers at the University of São Paulo have found that infection by the novel coronavirus can cause lasting alterations to semen and testosterone production even in people who have mild or asymptomatic COVID-19.
After six weeks of a low-calorie diet, the pattern of gene expression in obese women became more similar to that of non-obese women in the same age group. Genes associated with cancer became less active.
The warning came from a FAPESP-held webinar in which researchers discussed the present-day and historical factors that explain the inadequate response to the pandemic in Brazil’s North region.
The third event in the series FAPESP 60 Years featured three researchers who are leading experts in the area: Donatella della Porta, Sérgio Adorno, and Michel Misse.
A system for identifying people and controlling access developed by a Brazilian startup lets guests check in remotely and open room doors using smartphones.
The hypothesis was raised by scientists at a FAPESP-funded research center, on the basis of an epidemiological survey involving 1,744 Brazilian couples where at least one partner was infected.
With the support of NGOs, universities and business, the inhabitants of small towns in the Amazon are practicing a self-sustaining circular economy in which waste is converted into inputs for production.
Analysis of data for more than 400,000 people shows that increasing the proportion of vigorous exercise reduces mortality by 17% compared with people who get only moderate exercise.
Many patients suffer from a significant decline in immunity lasting for years after they are discharged from hospital. In an article published in the journal Immunity, Brazilian researchers reveal why this happens.
Researchers at the Federal University of São Carlos in Brazil in partnership with University College London (UCL) in the UK analyzed data for 2,294 individuals aged 60 or more who were monitored for eight years. Results were published in the journal Age and Aging.
Scientists at a FAPESP-funded research center investigated the mechanism that produces the main enzyme involved in the virus’s replication in cells. The findings are reported in the Journal of Molecular Biology.
The researchers combined VOD, an indicator of the amount of water in vegetation, with remote sensing data from optical satellites. The innovative strategy described in Remote Sensing provides a more comprehensive understanding of the biomass changes caused by fire.
