Preliminary findings have not yet been published but were presented during a conference held at the University of Campinas.
With FAPESP’s support, Hytron has developed a containerized solution for hydrogen production via ethanol reforming that eliminates the need for shipping by tanker trucks. The equipment can supply the gas to factories and vehicle service stations.
Filaments made of polymer-coated iron oxide nanoparticles are obtained by exposing the material to a magnetic field under controlled temperature. The applications are myriad and include transporting substances into cells or directing fluids.
A study by researchers at the University of São Paulo showed that the blood serum of severe patients contained high levels of the neurotransmitter acetylcholine and lipid mediators derived from arachidonic acid. The discovery may help improve the prognosis of such patients and the treatment available to them.
Brazilian researchers applied an examination protocol based on an analysis of 12 lung regions to 180 severe patients and found that the higher the lung ultrasound score the greater the risk of ICU admission, intubation and death.
Technology based on nanoparticles identifies IgG antibodies and costs only about a fifth of similar devices now on the market. It was developed by scientists at the University of São Paulo and Brazilian startup Biolinker.
Mapping of toxins from pit viper and tarantula reveals peptides that could lead in future to the development of novel drugs for cardiovascular problems and cancer, besides anti-bacterial, anti-fungal, and anti-viral potential.
More than 1,000 volunteers completed an online questionnaire designed by Brazilian researchers. The results show that more women are cooking, sitting down to eat, snacking between meals, and ordering takeaway meals, while dieting and supermarket shopping have declined.
The hormone acts as a barrier against SARS-CoV-2, blocking the expression of genes that encode proteins in cells serving as viral entry points, according to a study by researchers at the University of São Paulo.
Researchers at York University in Canada and the University of Campinas in Brazil used mathematical modeling to estimate the short-term impact of vaccination. Abandoning non-pharmaceutical interventions too soon could cancel out the benefit, they warn.
Based on a reaction between yeast and the novel coronavirus, the test will rapidly detect the presence of SARS-CoV-2 in saliva and will be available by mid-2021.
The phenomenon may be associated with a deficiency of the protein mitofusin-2 in the mother’s eggs, which affects the shape and functioning of mitochondria. The finding was based on experiments with mice conducted at the Federal University of São Carlos and reported in the journal Molecular Human Reproduction.
According to a study published in Frontiers in Immunology, the reason is their genetic heterogeneity and lack of proportional representation in the Brazilian bone marrow bank.
Researchers who studied riverine insect communities in the Atlantic Rainforest and Finland’s boreal forests discovered that random events are more frequent in Brazil.
