Researchers at the Center for Research on Redox Processes in Biomedicine (Redoxome) in Brazil have identified extracellular matrix proteins modified by the action of hypobromous acid in normal and fibrotic lung tissues, suggesting a possible physiological role for protein bromination. This is the first study to identify brominated proteins in pulmonary fibrosis and non-fibrotic lung tissue. The extracellular matrix is a complex three-dimensional network of proteins and other macromolecules [...]

The skin or peel of the jaboticaba berry (Plinia jaboticaba), a native of the Brazilian Atlantic Rainforest, is usually thrown away because of its astringency (due to an abundance of mouth-puckering tannins), yet it can be a powerful ally in the treatment of obesity and metabolic syndrome, according to an article published in the journal Nutrition Research. Conducted by researchers at the State University of Campinas (UNICAMP) in São Paulo state (Brazil), the study [...]

Although the rate of deforestation in the Brazilian Amazon fell in 2023, the region is faced with another challenge in the shape of fire affecting the native vegetation that has so far been spared destruction. An article published in the journal Global Change Biology warns that wildfires in old-growth forests rose 152% last year compared with 2022, despite a drop of 16% in the total number of fires throughout the Amazon and a 22% drop in deforestation. In an analysis of satellite images, the [...]

Aerobic training is known to regulate blood pressure more effectively when practiced in the evening than in the morning. Researchers who conducted a study of elderly patients at the University of São Paulo's School of Physical Education and Sports (EEFE-USP) in Brazil concluded that evening exercise is better for blood pressure regulation thanks to improved cardiovascular control by the autonomic nervous system via a mechanism known as baroreflex sensitivity. The study is published [...]

THURSDAY, May 16, 2024 (HealthDay News) -- People with post-traumatic stress disorder (PTSD) face more than triple the odds of bruxism, otherwise known as teeth grinding, a new study finds. The small study of 76 Brazilian adults (38 diagnosed with PTSD and 38 without the condition) found much higher incidence of daytime teeth grinding. “Our study showed that PTSD can be manifested orally, in bruxism and a higher level of pain after a clinical dental examination. This requires joint [...]

Bacteria of the phyla Firmicutes and Proteobacteria, including those of the genus Streptococcus, are the most common microorganisms found in the saliva of swine, which contains a different microbiota from swine feces and the environment in which the animals live. These were among the findings of a study by researchers at the University of São Paulo (USP) in Brazil and Pennsylvania State University in the United States. According to the researchers, this was the first study ever to [...]

According to an article published in the journal Clinical Oral Investigations, people who suffer from post-traumatic stress disorder (PTSD) often report constant clenching or grinding of the teeth during the day, a condition known as awake (or diurnal) bruxism. Its prevalence in the general population varies from 8% to 30%. The study, which included clinical examination of 76 patients and controls, highlights the importance of collaboration by dentists and psychiatrists to diagnose both [...]

Researchers from the Federal University of São Carlos (UFSCar) have discovered a way to use old leaves as sensors. The new technique effectively laser-prints the surface of the leaves, turning them into something entirely unexpected. The new technique has been developed as an alternative to 3D printing as a means to more sustainable ways to make things like sensors. By using leaf litter as the raw material, a new innovative approach has now been found. Creating sensors through 3D [...]

The silver croaker (Plagioscion squamosissimus), a fish native to the Amazon (corvina or pescada-branca in Portuguese), is the most probable cause of a sharp fall in the diversity of native species in the Jaguari reservoir, the Jaguari River and Rio do Peixe, all of which are part of the Cantareira Water Production System and the Paraíba do Sul Basin in São Paulo state, Brazil. As a top predator in the food network, the invader has negatively affected local biodiversity by [...]
