When Brazilian immunologist Helder Nakaya visited Evandro Chagas Institute in Belém (the capital of Pará state, Brazil) in 2017, there was a commotion because one of its best microscopists was retiring and much of the knowledge used for fast and accurate identification of the protozoan Leishmania would be lost."I was dismayed by the waste of losing all that expertise, which it had taken decades to acquire. We began researching and trying to train a computer program to use [...]

When our cells process the oxygen we breathe and the food we eat every day in order to survive, they generate potentially toxic by-products popularly known as "free radicals". Some of these molecules perform functions essential to the organism, but if there are too many of them the cells' internal structures can be damaged, preventing the cells from functioning properly and potentially leading to chronic disease. This process is called oxidative stress.Our bodies contain a [...]

Washington [US], August 12 (ANI): A study shows how SARS-COV-2 infects brain cells called astrocytes, causing structural changes in the brain. Infection with SARS-CoV-2 can cause brain alterations and neurocognitive dysfunction, particularly in long COVID-19 syndrome, but the underlying mechanisms are elusive. Daniel Martins-de-Souza and colleagues used MRI to compare brain structure in 81 study participants recovering from a mild COVID-19 infection and 81 healthy individuals. The authors [...]

The conversion took place under ambient temperature and pressure conditions, which could enable methane, a potent greenhouse gas, to be used to produce fuel. Credit: UFSCAR A group of researchers has succeeded in converting methane into methanol using light and dispersed transition metals such as copper in a process known as photo-oxidation. According to an article reporting the study published in Chemical Communications, the reaction was the best obtained to date for conversion of methane [...]

The female patient had a genetic disease that dysregulates the immune system, impairing its inflammatory response and antibody production. The virus was eliminated after week-long ingestion of breast milk donated by a woman who had been vaccinated against SARS-CoV-2. The case is reported in the journal Viruses by researchers at the University of Campinas in Brazil The female patient had a genetic disease that dysregulates the immune system, impairing its inflammatory response and antibody [...]

The finding comes from a clinical trial by researchers at the University of São Paulo who recruited 32 male volunteers and have now published the results in Clinical and Experimental Hypertension.

Newswise — for the first time by Brazilian researchers. According to an article published in the International Journal of Pharmaceutics, the potential treatment was shown to be effective in isolated cells and animal models thanks to a combination of nanotechnology, chemotherapy and a monoclonal antibody. Glioblastoma multiforme accounts for 60% of all brain tumors in adults and is also the most aggressive type of brain cancer. Even after surgery, radiation therapy and conventional [...]

Resistant or refractory hypertension is high blood pressure that does not respond to aggressive... medical treatment, defined as daily administration of at least three classes of antihypertensive drug (including a diuretic) at maximally tolerated doses. Patients with the disease are at high risk of cardiovascular complications, including stroke and heart failure. At the University of Campinas's School of Physical Education (FEF-UNICAMP) in São Paulo state, Brazil, the [...]

Brazil-based major international aerospace group Embraer has announced that it is partnering with two other Brazilian institutions to create an Engineering Research Centre (ERC) into the future of air mobility. The other two bodies are the Federal Government's Aeronautical Technology Institute (abbreviated to ITA in Portuguese) and the São Paulo State Foundation for the Amplification of Research (FAPESP), a research funding agency. Embraer, ITA and FAPESP will jointly invest [...]
