The solution developed by the firm, with FAPESP’s support, is currently being validated by UN’s International Atomic Energy Agency.
An interdisciplinary approach tested at the Federal University of São Paulo combined clinical, nutritional, psychological and exercise counseling. The intervention involved remote and in-person sessions, favoring adherence and lowering the cost to the health system.
In animal tests conducted at São Paulo State University (UNESP), the strategy reduced spleen and liver parasite numbers by 99.9%.
Researchers at the University of São Paulo analyzed data from 115 children who suffered from conditions considered syndromic (with several associated symptoms) and found a high incidence of overlapping genetic alterations. They argue that identification of genetic mutations can make diagnosis and treatment more accurate.
The opossum was found dead in a park in the center of Campinas, a large city in São Paulo state (Brazil), with the same viral variant as fruit-eating bats. These mammals are regularly detected in cities, where they are often attacked by dogs, so they can be considered sentinel species for infectious disease surveillance.Transmission from bats to opossums can occur through interaction among these animals while they are competing for habitats
A study conducted in a poor suburb of São Paulo city (Brazil) analyzed how low-income communities deal with the hardships deriving from the economic crisis that began in 2014 and worsened during the pandemic.
Blood pressure rose in offspring born to high-fructose rats, and physiological regulation of their cardiovascular system was impaired. High-fructose syrup is widely used as a sweetener by the food and beverage industry.
Through experiments in roundworms of the species C. elegans, scientists at a FAPESP-supported research center showed that lifespan is reduced when RNA transfer between cells in different tissues is dysregulated.
A study by Brazilian researchers shows that the pigment is present not only in the seeds but also in other organs of Bixa orellana, the Annatto tree. They investigated the genetic pathways involved in synthesis of the substance.
Considered an invasive species, Sus scrofa causes damage to farmers in an important part of Brazil’s savanna-like biome. The researchers analyzed 55 landscapes in São Paulo state, observing larger numbers of native mammals in areas with well-conserved vegetation and diversified crops, while native species richness was far lower in areas of monoculture.
