Preeclampsia, a complication of pregnancy characterized by high blood pressure and high levels of protein in the urine (proteinuria), indicating damage to the kidneys or other organ damage, is the main cause of maternal-fetal death in Brazil and the runner-up worldwide. In a Brazilian study published in the journal PLOS ONE, the pattern of substances present in patient blood samples varied according to the severity of the preeclampsia concerned. The findings from the study, which [...]

Solar ultraviolet radiation is one of the causes of a series of eye diseases, including cataracts and a type of corneal inflammation (photokeratitis), which can be delayed or prevented by using UV protection, with sunglasses being the most popular accessory for this function. However, a study published in the journal Research on Biomedical Engineering raises alarm bells by revealing shortcomings in this protection. The study analyzed the effectiveness of 12 models of sunglasses [...]

A recent study published in the Journal of Cancer Research and Clinical Oncology explored genetic predictors of prostate cancer progression to help identify its clinical outcomes. Conducted by researchers from the D'Or Institute for Research and Education (IDOR), the University of São Paulo (USP), and the São Paulo Cancer Institute (ICESP), the study focused on the role of the androgen receptor (AR), its variant AR-V7, and the p160 gene family. Prostate cancer: a complex [...]

In an article published in the journal Trends in Biochemical Sciences, Alicia Kowaltowski , full professor at the University of São Paulo's Institute of Chemistry (IQ-USP) in Brazil, advocates the "rewriting" of textbooks on the location of the electron transport chain in mitochondria and the role of sodium in mitochondrial respiration. Kowaltowski is a member of the Research Center for Redox Processes in [...]

More than half of Brazil's rivers are at risk of reduced flow due to water seeping into underground aquifers. This is the result of an analysis of 17,972 wells throughout the country. Of these, 55.4% had water levels below the surface of the nearest rivers. This difference in hydraulic level creates a gradient that favors the seepage of water from the river into the subsoil, which can turn rivers into water flow losers. The study, conducted by researchers from Brazil and abroad, [...]

Expanding aquaculture in the Amazon could provide nutritional and economic benefits at a fraction of the environmental cost of cattle grazing, according to a Jan. 24 paper in Nature Sustainability from Cornell researchers and colleagues in the U.S. and Brazil. Such expansion could also come with risks, especially the potential introduction of harmful non-native species, the paper finds. “Cattle production is one of the most important drivers of deforestation in the Amazon,” said Felipe [...]

The scenario is common. An elderly person seems to be in good health until one day they suffer a fall and from then on their quality of life begins to deteriorate. Even if there are no serious consequences such as injuries, fractures or head trauma, falls usually lead to reduced mobility and consequently to a loss of independence and autonomy. The problem is so worrisome – falls are the second leading cause of injury-related death among adults aged 65 and over in the world, according [...]
