The international trade in timber, tobacco, cocoa, coffee and cotton accounts for a high proportion of malaria risk in exporter countries, according to a collaborative study by scientists in Brazil and Australia published in Nature Communications.
The device will identify parts of the virus’s RNA in the saliva of infected subjects. Other initiatives by the research group at the Federal University of São Carlos include developing sensors to look for the pathogen in the air and in sewerage systems.
Strategy would maintain economic activity and protect healthcare services, according to system developed by a research center supported by FAPESP.
Higher blood glucose levels captured by defense cells provide energy for augmented viral replication, triggering overwhelming immune response that kills lung cells.
This study analyzes the prevalence of factors that increase the risk of severe manifestations of COVID-19, such as old age, chronic disease, obesity and smoking, among others. The proportion of the most susceptible people is 80% among those with less schooling
On average, more than 4% of the studied forest fragments have regenerated naturally in the past 50 years. In certain forests near the Serra do Mar ridge, regeneration has reached 50%. The study used artificial intelligence to compare satellite images and aerial photographs taken in 1962.
Created at the University of São Paulo’s Engineering School (POLI-USP), the machine costs approximately 7% as much as a conventional ventilator and can be freely manufactured by companies that obtain approval from the national health surveillance authority.
Estimate is based on testing of 700 inhabitants of Ribeirão Preto in early May. Another round of testing will be conducted in June. The study is carried out by the University of São Paulo in partnership with the city’s health department.
Dr. Elnara Negri, who works in São Paulo City at the largest hospital complex in Latin America, advocates the use of the anti-coagulant drug heparin to treat complications caused by novel coronavirus.
A group of scientists in the state of São Paulo plan to determine whether a sudden loss of smell is an early indication of COVID-19.
Study shows that the 20-39 age group accounted for almost half the cases confirmed in the first month, possibly explaining why a smaller proportion of the total number infected were hospitalized in the period.
Laboratory tests conducted by collaborating Brazilian and European researchers showed that heparin alters the shape of the protein used by SARS-CoV-2 to penetrate host cells.
Researchers at the University of Campinas partner with biotech startups to promote local production of hitherto imported reagents. The goal is to increase Brazil’s capacity to perform RT-PCR tests, considered the gold standard for COVID-19 diagnosis.
3D printed face shields are worn by frontline health workers over a conventional surgical mask.
Brazilian researchers show that the virus can infect different placental regions and that collection and storage methods should be taken into consideration to ensure that the results are trustworthy and representative.
Digital tool developed at the University of São Paulo’s Mathematics and Computer Sciences Institute (ICMC-USP) in São Carlos refines projections for the spread of the pandemic.
Brazilian researchers are conducting tests with cultured cells to find out how COVID-19 changes patterns of proteins and other metabolites present in samples.
Scientists in Butantan Institute’s Special Vaccine Development Laboratory will couple SARS-CoV-2 antigen to bacterial membrane in order to trigger defense against coronavirus.
Based on the Internet of Things, the system was developed in a project supported by FAPESP. Patients can be advised to seek hospital care if they detect a deterioration in clinical signs.
A drop of 33% in levels of nitrogen dioxide (NO2) is associated with a reduction in diesel vehicle traffic and industrial production due to isolation measures taken to slow the spread of novel coronavirus.
This study shows that patients develop alterations in a type of leukocyte at the initial stage of the disease. This discovery paves the way for the enhanced diagnosis and treatment of this type of tumor.
The dysregulation appeared to affect communication among neurons in the subjects of the study, which was conducted in Brazil. The discovery could improve diagnosis, which is currently based on the clinical analysis of symptoms.
Several initiatives are pursuing alternatives to increase the number of diagnostic tests performed in Brazil. Research groups who previously developed low-cost rapid tests for Zika fever and other viral diseases are adapting these models for use in detecting SARS-CoV-2.
A drastic reduction in traffic due to the coronavirus lockdown resulted in a rapid decrease in airborne pollution: The levels of carbon monoxide fell by 50% in São Paulo City in a single week.
Developed with FAPESP’s support via its small business program, the N95-type respirator is made of material containing silica-silver microparticles with antimicrobial and antifungal properties that hinder surface adhesion by SARS-CoV-2.
