Researchers from the University of São Paulo in Brazil have discovered that silver nanoparticles produced by a fungus called Trichoderma reesei might be an effective way to prevent and treat COVID-19. In tests carried out on hamsters, the silver nanoparticles were shown to block the virus from entering cells and reduce the amount of virus in the lungs. Even more promising, the nanoparticles helped reduce lung inflammation—a major complication of severe COVID-19. The [...]

Silver nanoparticles produced by the fungus Trichoderma reesei could become important allies in the prevention and treatment of COVID-19. Tests carried out on hamsters showed that they not only inhibited the infection but also reduced the viral load in the lungs, easing inflammation in the rodents. The study, supported by FAPESP , paves the way for the development of nasal sprays and other products to combat several viral diseases, such as HIV/AIDS, shingles and [...]

One of the pillars of the Brazilian economy and one of the sectors responsible for the highest greenhouse gas emissions, beef production in Brazil, as it is currently practiced, emits more than twice the limit needed to meet international environmental targets. This is one of the conclusions of a study published in the journal Environmental Science and Pollution Research. The work includes an evaluation of projected emissions scenarios, along with an economic assessment. The [...]

A Brazilian study of 728 children up to one year of age shows that the consumption of ultra-processed foods can negatively affect the diversity and abundance of the intestinal microbiota, with a more pronounced effect in children who are not breastfed. The results were published in the journal Clinical Nutrition, as part of the "MINA Study – Maternal-Infant in Acre: birth cohort of the Brazilian Western Amazon" , which is following a group of children [...]

A global study links ultra-processed foods to tens of thousands of preventable deaths annually, especially in countries like the U.S. and the U.K. with high consumption rates, prompting urgent calls for dietary reform and public health intervention. A recent study in the American Journal of Preventive Medicine investigates the risk of all-cause mortality associated with the consumption of ultra-processed foods (UPFs) and their epidemiologic burden in eight countries. What are [...]

Difficulty finding words or the habit of substituting them with others that are similar semantically – such as knife and cutter – or phonologically – such as knife and wife – are usually the first symptoms of a type of dementia known as primary progressive aphasia (PPA). Another sign is a subtle difficulty in forming sentences, evidenced by verbal and nominal agreement errors that have never been made before, or reversal of word order, for example. Writing errors [...]

1/5 Ultraprocessed foods could be killing more Americans than fentanyl, a new study has found. The unhealthy food group, popularised for its convenience, often contains high levels of sugar, salt and unhealthy fats – and are believed to make up over 70 per cent of the US food supply. Australians also consume a large amount of ultra-processed foods, also known as UPFs, with research suggesting they make up around 40 to 42 per cent of their daily energy intake. Alarmingly, [...]
