An extracellular matrix obtained by controlled decellularization is used to reconstruct the liver with human-like characteristics Researchers at the Human Genome and Stem Cell Research Center (HUG-CELL), hosted by the University of São Paulo’s Institute of Biosciences (IB-USP) in Brazil, have developed a technique to reconstruct and produce livers in the laboratory. The proof-of-concept study was conducted with rat livers. In the next stage of their research, the scientists will [...]

Researchers analyzed socioeconomic and environmental indicators for the 180 municipalities in the mega-region around São Paulo state capital, detecting environmental inequity and dependency. In Brazil, researchers are puzzling over socioeconomic and environmental indicators that do not add up. They are concerned with what they call the São Paulo Macrometropolitan Area, a mega-region comprising five metropolitan areas in the state of São Paulo with a total of 180 [...]

A study conducted at the University of Campinas (UNICAMP) in the state of São Paulo, Brazil, shows that compounds produced by gut microbiota (bacteria and other microorganisms) during fermentation of insoluble fiber from dietary plant matter do not affect the ability of the novel coronavirus SARS-CoV-2 to enter and replicate in cells lining the intestines. However, while in vitro treatment of cells with these molecules did not significantly influence local tissue infection, it reduced [...]

Brazilian researchers obtain more efficient red bioluminescence   Brazilian researchers obtain more efficient red bioluminescence Brazilian researchers obtain more efficient red bioluminescence 0 Share Luciferin-luciferase system developed in collaboration with Japanese researchers produces brighter and longer-lasting far red light. The innovation can be used to image cells and tissues for diagnosis and biomedical research. Credit: International Journal of Molecular [...]

Octopuses are known to sleep and to change color while they do it. Now, a study publishing March 25 in the journal iScience finds that these color changes are characteristic of two major alternating sleep states: an “active sleep” stage and a “quiet sleep” stage. The researchers say that the findings have implications for the evolution of sleep and might indicate that it’s possible for octopuses to experience something akin to dreams. Scientists used to think that [...]

Group affiliated with a FAPESP-supported research center showed that the parasite blocks the action of an enzyme using autophagy Researchers have succeeded in revealing the arsenal used by protozoans of the genus Leishmania in human cells to make leishmaniasis more severe, especially in cases of the mucocutaneous variety of the disease, which can cause deformations in patients. The discovery points the way to a search for novel treatments for the disease as well as casting light on a [...]

Brazilian researchers tested the capacity of different materials to produce sensors for the detection of PCA3, a gene that is overexpressed in prostate cancer. The technique can also be used to diagnose infectious diseases, including COVID-19. The efficacy of biosensors used in clinical tests depends critically on the surface of the device on which the biorecognition molecules are immobilized. This surface can be adjusted and sometimes controlled using self-assembled molecular monolayers as [...]

Developed by researchers at the University of São Paulo, the non-invasive methodology facilitates identification of immature or poor-quality seeds without destroying them or creating residues. In Brazil, researchers affiliated with the Center for Nuclear Energy in Agriculture (CENA) and the Luiz de Queiroz College of Agriculture (ESALQ), both part of the University of São Paulo (USP), have developed a methodology based on artificial intelligence to automate and streamline seed [...]

In a study of the effects of cigarette smoking on exacerbation of the disease, scientists at a FAPESP-supported research center identified a novel pathway in the inflammatory process relating to bone damage In a study aimed at investigating the mechanism responsible for exacerbating rheumatoid arthritis in smokers, researchers at the Center for Research on Inflammatory Diseases (CRID), linked to the University of São Paulo (USP) in Brazil, discovered a novel path in the inflammatory [...]
