Discovery of Zika virus in monkeys suggests disease may also have wild cycle
Publicado em 30 de outubro de 2018
Zika virus has been detected in dead monkeys found in Brazil near São José do Rio Preto, São Paulo State, and Belo Horizonte, Minas Gerais. The animals had been shot or beaten to death by locals who thought they had yellow fever. In fact, the monkeys were not bearers of that disease, but infection by Zika virus had made them sick and more vulnerable to attack by humans.
"The discovery shows the potential exists for Zika to establish a sylvatic transmission cycle [involving wild animals] in [...]

Cappuccino made with jackfruit seed flour has chocolate aroma
Publicado em 26 outubro 2018Cappuccino made with jackfruit instead of cocoa powder. According to a new study, roasted jackfruit seeds can replace between 50% and 75% of the cocoa that is blended with milk and coffee to make cappuccino without impairing flavor or aroma. "Flour made from roasted jackfruit seeds naturally releases a mild chocolate aroma," said food scientist Fernanda Papa Spada , a recipient of a scholarship , from São Paulo Research Foundation - FAPESP, who performed the study at the University of São [...]ver notícia -
Chemotherapy drug paclitaxel also acts as an immune response modulator
Publicado em 24 outubro 2018Researchers in Brazil have discovered a new effect of a drug widely used as a chemotherapeutic agent and offered to patients free of charge by SUS, the national health service. Paclitaxel is prescribed for the treatment of breast, lung and ovarian cancer, as well as other types of tumors. It is known to act as an antineoplastic agent, inhibiting the growth of abnormal tissue due to cell proliferation. The new study shows that it can also reactivate the patient's immune response, thus combating [...]ver notícia -
Colored filter improves dyslexic children's reading speed
Publicado em 18 outubro 2018Reading, one of the most difficult activities for children with dyslexia, can be improved by the use of green filters. A study described in an article by Brazilian and French researchers reports increased reading speed for nine- and ten-year-old volunteers with dyslexia who used green filters. The filters had no effect on age-matched children without dyslexia. Colored filters for the treatment of learning disabilities were first patented in 1983. They were also designed for use by children [...]ver notícia -
Food transports Syrian refugees' imaginations to a place that no longer exists
Publicado em 15 outubro 2018Cuisine can be considered a set of practices that permeate many aspects of life. A dish may recall someone special. The symbolic value of food may also reside in aromas and seasoning, which immediately bring to mind a place or past situation, along with everything that was happening and being experienced at the time. There's also the famous case of the dish no one is able to cook successfully, usually a recipe inherited from grandma. Failure is probably due to the lack not of a secret [...]ver notícia -
Early Alzheimer's brain pathology linked to psychiatric symptoms
Publicado em 12 outubro 2018UC San Francisco researchers, in collaboration with the unique Brazilian Biobank for Aging Studies (BBAS) at the University of São Paulo, have shown that the earliest stages of the brain degeneration associated with Alzheimer's disease (AD) are linked to neuropsychiatric symptoms including anxiety, depression, loss of appetite, and sleep disturbances. The findings -- published in their final version October 15, 2018 in the print edition of the Journal of Alzheimer's Disease following [...]ver notícia -
Physical exercise improves the elimination of toxic proteins from muscles
Publicado em 27 setembro 2018A study published in Scientific Reports by researchers at the University of São Paulo (USP) in Brazil, in partnership with colleagues in the United States and Norway, shows that the lack of muscle stimulus results in a buildup of inadequately processed proteins in muscle cells and consequently leads to muscle weakness or wasting. This is a typical muscle dysfunction condition that affects the elderly or individuals suffering from sciatic nerve injury, something usually verified in bedridden [...]ver notícia -
Four extremely young asteroid families identified
Publicado em 24 setembro 2018Four families of extremely young asteroids have been identified by researchers affiliated with São Paulo State University (UNESP) in Guaratinguetá, Brazil. An article on the discovery has been published in Monthly Notices of the Royal Astronomical Society. "We identified the new families by means of numerical simulation using the backward integration method (BIM), which is much more precise than other methods for dating asteroid families. But BIM only works for really young families that are [...]ver notícia -
Study reveals a promising alternative to corticosteroids in acute renal failure treatment
Publicado em 20 setembro 2018A protein produced by the human body appears to be a promising new drug candidate to treat conditions that lead to acute renal failure. This is shown by a study conducted at São Paulo State University (UNESP) in São José do Rio Preto, Brazil. The results of the study, published in the journal Scientific Reports, indicate that the protein galectin-1 has anti-inflammatory properties capable of minimizing the damage done to kidney cells by hypoxia (lack of oxygen) and reperfusion (restoration [...]ver notícia -
Study on jararaca pit vipers links 'giant' specimens proliferation to predators
Publicado em 18 setembro 2018In São Paulo, Brazil's largest city, it is easier to find "giant" jararaca pit vipers ( Bothrops jararaca) in a small fragment of Atlantic Rainforest surrounded by urban sprawl than in a nature reserve that is 16 times larger, even though more food is available for snakes in the latter. A new study suggests that the difference may be due to the number of predators in each habitat and not to the availability of food, as the researchers supposed at the outset. Their findings have been [...]ver notícia
