Pancreatic cancer has recently been included in the list of diseases about which Brazil's National Cancer Institute (INCA) periodically publishes statistics. Although it is not the most frequent type of cancer, its high lethality makes it one of the leading causes of death from cancer in Brazil, partly owing to late diagnosis. "It's striking how little data on the disease is available in Brazil and indeed in Latin America as a whole. There are no studies on pancreatic cancer [...]

The rainforest in the Amazon basin transpires vast amounts of gaseous isoprene. Until now, it was assumed that this molecule is not transported far up into the atmosphere, as it rapidly declines when exposed to light conditions. The CAFE-Brazil measurement campaign provided data for two studies - now published as the Nature cover story - which demonstrate, however, that nocturnal thunderstorms transport the isoprene to an altitude of up to 15 kilometers. There, it reacts to form chemical [...]

A study in Brazil involving 89 father-mother-baby triads points to an association between paternal overweight and newborn birth weight: the higher the father's body mass index (BMI, weight divided by height squared), the lower the baby's birth weight. An article on the study is published in the International Journal of Obesity. The findings reinforce the idea that anthropometric issues are not the sole responsibility of the mother and that the father should also strive [...]

Household utensils or objects for ritual use, gourds are present in various cultural environments in Brazil, especially in indigenous or riverside communities, but also in large cities in the Amazon region, such as Belém, capital of the state of Pará. "Gourds are believed to be among the first cultivated plants in the Amazon, and their use is probably even older than that of ceramics," says researcher Renata Maria de Almeida Martins , professor at the Faculty [...]

Brazilian scientists have determined that ancient specimens of partially domesticated maize (Zea mays, also known as corn) originally from Peruaçu Valley in Minas Gerais state (Brazil) were the farthest from Mexico, the plant's historic center of origin, of any finds made so far. An article describing their research is published in the journal Science Advances. The study was led by researchers affiliated with the University of São Paulo (USP) and EMBRAPA, the [...]

A study by researchers working in Brazil shows that antimicrobial photodynamic therapy in which blue light targets annatto colorant is a feasible and effective option for treatment of halitosis in mouth-breathing children. Annatto is an orange-reddish pigment derived from the seeds of Bixa orellana (achiote or urucum), a shrub native to tropical parts of the Americas. Mouth breathing dries up the saliva, reducing its antibacterial and cleansing effects, so that halitosis is likely to [...]

The lack of knowledge about the benefits of human genomics for public and individual health, together with the scarcity of qualified professionals and low investment, are among the challenges that countries need to overcome in order to implement equitable public policies in the area. To address these issues, it is essential to launch initiatives that clearly communicate the potential of genomics to different audiences and involve all interested sectors. In addition, the implementation of [...]
