Study effects paradigm shift in the understanding of how red rot attacks sugarcane
Publicado em 14 junho 2021
Researchers at the University of São Paulo discover that the fungus Fusarium verticillioides uses volatile compounds to manipulate insects and plants, promoting its own dissemination
The fungus Fusarium verticillioides is one of the causes of red rot, the most serious sugarcane disease. Losses average around USD 1 billion per harvest in Brazil alone.
The traditional approach to the etiology of this disease is that it is triggered by Diatraea saccharalis, a moth usually referred to as [...]

Scientists decipher the structure of protein found in parasites that cause neglected tropical diseases
Publicado em 08 janeiro 2021Brazilian researchers have managed to decipher the structure of a protein found in parasites that cause neglected tropical diseases, paving the way to the development of novel medications. Thanks to the discovery it will be possible to seek more potent molecules capable of destroying the pathogens directly, with fewer adverse side-effects for patients. The study detailed the structural characteristics of the protein deoxyhypusine synthase (DHS), found in Brugia malayi, one of the [...]ver notícia -
Study: Toxins produced by tube-dwelling anemones have pharmacological potential
Publicado em 30 outubro 2020Researchers based in Brazil and the United States have completed the first-ever mapping exercise to profile the toxins produced by tube-dwelling anemones, or cerianthids, a family of marine animals belonging to the same phylum (Cnidaria) as sea anemones, jellyfish and corals. The analysis revealed that the toxins that can act on the nervous system, cardiovascular system, and cell walls, among other functions, paving the way to the discovery of novel medications. “Tube anemones and sea [...]ver notícia -
Researchers in Brazil develop low-cost mechanical ventilators
Publicado em 03 junho 2020A group of researchers at the University of São Paulo’s Engineering School (POLI-USP) in Brazil have developed a mechanical ventilator that costs only approximately 7% as much as a conventional ventilator. Called Inspire, it has an open patent allowing royalty-free manufacturing, although as a life support device, its distribution is controlled. A pilot batch will be produced by the Brazilian Navy for use in clinical trials. Twenty companies are interested in making the [...]ver notícia -
Startup supported by FAPESP will supply mechanical ventilators to Brazil’s Health Ministry
Publicado em 29 maio 2020On April 8, 2020, São Paulo-based Magnamed signed an agreement with Brazil’s Health Ministry for the supply of 6,500 mechanical ventilators by August of this year. The agreement is designed to help meet growing demand for ventilators from hospitals across the country as they struggle to provide critical care for COVID-19 patients. To achieve this goal, Magnamed will partner with the following companies: Positivo, Brazil’s largest computer maker; Suzano, one of the [...]ver notícia -
54.8% of COVID-19 cases imported to Brazil by March 5 came from Italy
Publicado em 07 abril 2020In contrast with China and other countries where the disease spread slowly, in Brazil more than 300 people started the epidemic; most were passengers flying in from Italy Italy was the main origin of the individuals who first brought the novel coronavirus to Brazil, according to a study by Brazilian researchers in collaboration with colleagues in the United Kingdom, Canada and the United States. The COVID-19 pandemic arrived in Brazil between February and early March. “In contrast with [...]ver notícia -
A study investigating genetic mechanisms underlying resistance to leishmaniasis
Publicado em 24 março 2020In an article published in Scientific Reports, researchers affiliated with the University of São Paulo (USP) in Brazil describe experiments performed with mice that show how genetic factors can determine whether an individual is susceptible or resistant to leishmaniasis. According to the authors, the results will contribute to a better understanding of leishmaniasis in humans and help to clarify why only some of those individuals infected develop the disease. Leishmaniasis is caused by [...]ver notícia
