Sugar added to food may be the “villain” when it comes to the relationship between stomach cancer and an unhealthy diet, while salt increases the risk of tumors in people with habits considered healthy. This is the result of a study carried out in Brazil and published in the scientific journal BMC Medicine. The study considered an unhealthy dietary pattern (UDP) to be one that included high consumption of processed meats, carbonated drinks high in sugar, and fast food. On the other [...]

Study Links Sugar and Salt to Stomach Cancer Recent research has shed light on the intricate relationship between dietary habits and the development of stomach cancer. A study conducted in Brazil and published in the esteemed journal BMC Medicine has revealed compelling findings regarding the impact of sugar and salt consumption on the risk of stomach tumors. The Role of Sugar in Stomach Cancer Sugar, often considered a dietary "villain," has been implicated in the development of [...]

Some families of caterpillars (larvae of butterflies and moths) have developed a specific kind of interaction with ants. One of these families (Riodinidae) includes two species that interact solely with two species of ants. In a study published in the journal Insect Science, researchers in Brazil affiliated with the University of São Paulo (USP), the Federal University of Rio Grande do Sul (UFRGS) and the Federal University of Alagoas (UFAL) show that this interaction is highly specific [...]

 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 [...]

 A diet rich in produce such as grapes, strawberries, açaí, oranges, chocolate, wine and coffee can reduce the risk of metabolic syndrome by as much as 23%, according to the findings of a study involving more than 6,000 Brazilians, the largest in the world to associate the effects of consuming polyphenols with protection against cardiometabolic problems. An article on the study is published in the Journal of Nutrition.  Metabolic syndrome, a cluster of metabolic abnormalities and [...]

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, [...]

Agência FAPESP* – 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 Biomedicine (Redoxoma), a Research, Innovation, and [...]

Pancreatic cancer, a global challenge, sees only 13% survival rate after 5 years. In Ireland, 900 cases yearly with 820 deaths. Early detection crucial for patient survival. Pancreatic Cancer: Global Prognosis and Research Pancreatic cancer (PC) stands as one of the most challenging battles in the realm of oncology, with a global prognosis that continues to present a grim reality. Statistics reveal that a mere 13% of individuals diagnosed with PC manage to surpass the 5-year survival mark [...]

The reemergence of dengue virus serotype 3 (DENV-3) in Brazil after 17 years could help worsen fresh outbreaks of the disease there since the population is not immunized against this serotype, and serotypes 1 and 2 (DENV-1 and DENV-2) continue to circulate. The warning features in an article written by researchers at the São José do Rio Preto Medical School (FAMERP) in São Paulo state, and published in the Journal of Clinical Virology. “The last significant DENV-3 epidemic in [...]
