A multicenter research team investigated an outbreak in 2019, which proved to be due to a subtype of the pathogen that causes Newcastle disease. According to the researchers, the risk to humans and poultry is low.
These factors combined have worsened the severe drought conditions in the transition zone between the eastern Amazon and the Brazilian savanna, where the main soybean-producing region (MaToPiBa) is located. The researchers who detected the trend warn that crop yields could fall.
Brazilian researchers conducted a randomized clinical trial to test the safety and efficacy of a 12-week home exercise program for 32 volunteers who had been hospitalized after contracting COVID-19.
Experiments in mice show for the first time that mutant mitochondrial DNA builds up during the final stage of egg formation. The discovery will serve as a basis for novel strategies to prevent transmission.
A system developed by a startup supported by FAPESP proves capable of predicting diabetic foot with over 85% accuracy. Foot complications occur in 34% of diabetics.
Brazilian researchers analyzed data for 2,777 patients hospitalized between January 5 and September 12, 2021. For those who had been fully vaccinated, being over 60 and having kidney failure were the sole predictors of hospitalization and death from COVID-19.
A study by researchers in Brazil and the UK reinforces the hypothesis that Drosophila melanogaster has a mutualistic relationship with Wolbachia bacteria. Their findings can help make the fight against mosquito-borne diseases more effective.
Experiments were conducted on mice by a group at the University of São Paulo. The results, reported in the journal Endocrinology, could have future implications for therapies to control body weight.
Patients submitted to a procedure that “resets” the immune system were tracked for a year by scientists at a FAPESP-supported research center. Their clinical improvement correlated with renewal of a group of defense cells known as B lymphocytes.
A study led by Brazilian researchers measured species numbers and attributes, as well as carbon dynamics, in two areas of the Brazilian savanna – one is regularly burned and no fires have occurred in the other for 16 years.
Brazilian researchers tracked 425 patients for six to nine months after hospital discharge. Over half reported memory decline, and tests showed significant cognitive impairments in the group.
A group at São Paulo State University (UNESP) is working on pharmacological strategies to block sperm motility.
Although this variant of SARS-CoV-2 is less aggressive, the explosive growth of case numbers has again driven health services to the verge of collapse. Lack of tests and a “data blackout” at the Health Ministry make an accurate assessment of the situation impossible.
Survey by National Disaster Surveillance and Early Warning Center (CEMADEN) highlights simultaneity of extreme weather episodes due to heavy rain in North, Southeast and parts of Center-West, and drought in South and parts of Northeast.
Innovative, artificial intelligence-based methodology detects occurrences of Pleroma by identifying blooms, and maps distribution in biome.
An article in the Journal of Medical Virology by researchers affiliated with the Federal University of São Paulo in Brazil argues that this is the reason for the relatively small proportion of severe cases and deaths among vaccinated patients despite omicron’s greatly increased transmissibility.
The wearable device has screen-printed sensors on three fingers to detect the presence of toxic substances in fruit and vegetables. Prior preparation of samples is not required, and no waste is generated.
The clinical trial involved 44 volunteers with advanced bladder cancer. The award of a US patent should facilitate cooperation between the researchers and the pharmaceutical industry to proceed to the next stage of drug development.
The technique is used for in vitro studies of the behavior of astrocytes in a three-dimensional format, and can be adapted for neurons and other cell types. The model has been used to investigate the effects of COVID-19 on the central nervous system.
Researchers have found that nanoparticles resulting from human activities such as the burning of fossil fuels rapidly grow in the atmosphere and influence cloud formation. The discovery will help make meteorological models and climate change simulations more accurate.
A Brazilian startup has developed technology inspired by the soil mapping techniques used by the oil and gas industry to select drilling sites.
A randomized, double-blind, placebo-controlled clinical trial conducted by the University of São Paulo found that a vaccine taken sublingually for 18 months had positive results, reducing skin lesions and itchiness.
Research conducted at São Paulo State University (UNESP) in Brazil showed that the technique inhibits bacterial activity and can be used in the consulting room.
The program can be used to control the quality of the data obtained, sequencing environmental samples by means of a technique known as metagenomics, which shows how complete the sequences mapped are, and whether they are contaminated by genetic material from other microorganisms.
A system developed by Brazilian researchers detects the presence of the virus in a nasopharyngeal swab in less than a minute.
