A 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 ventilator, [...]

Exposure to ultraviolet (UV) radiation is a risk factor for skin cancer and other diseases. The risk increases when sunlight, the natural source of UV radiation, is combined with artificial sources such as UV lamps for medical therapy, among others. Detecting and measuring UV exposure in different environments was the scope of a research project conducted in Brazil at the São Paulo Federal Institute of Education, Science and Technology (IFSP) in collaboration with the University of [...]

Agência FAPESP – Developed by Biologix, a startup headquartered in São Paulo, Brazil, a sleep apnea home diagnostic and monitoring system based on the Internet of Things can be used for the remote monitoring of individuals with suspected COVID-19 or mild symptoms of the disease. The system can also be used to recommend transfer to a hospital if the patient's clinical signs worsen. Two private hospitals in São Paulo, the epicenter of the pandemic in Brazil, will [...]

Shortly after the explosion in microcephaly cases caused by Zika virus in Brazil in 2015-16, several scientific studies were published with evidence that the pathogen is capable of crossing the human placenta, the organ that keeps the fetus connected to the mother's body during pregnancy. From then on, the states began following a protocol established by the National Ministry of Health requiring collection of placental samples to help diagnose the disease in women with symptoms during [...]

Autism has long been associated only with behavioral and environmental factors, but the role of genetics in its development is now increasingly evident. Some 100 genes have been found to play a role in autism spectrum disorder, and another thousand are being studied to the same end. The diagnosis and treatment of the disorder on a genomic basis are hindered by this variability. However, a new study conducted at the University of São Paulo's Institute of Biosciences (IB-USP) in [...]

The hypothesis that blood clotting disorders may explain some of the worst symptoms of COVID-19, including respiratory failure and pulmonary fibrosis, was suggested in mid-April by researchers in Brazil affiliated with the University of São Paulo's Medical School (FM-USP) via an article accepted for publication by the Journal of Thrombosis. In less than a month, the topic had been highlighted in articles posted to the websites of Science and Nature, both of which are among the [...]

Immune system cells in the blood of breast cancer patients undergo alterations early in the disease course, according to a study published in the journal Clinical & Translational Immunology. The authors believe that this discovery may contribute to the early identification of aggressive tumors and help enhance personalized immunotherapy strategies in the future. The study was conducted while Rodrigo Nalio Ramos was doing a doctoral research internship at Claude Bernard University in Lyon, [...]

Exposure to bisphenol A (BPA), an industrial chemical used to make certain plastics and resins, inner coatings for food cans and bottle tops, thermal paper used in store receipts, dental sealants and so on, is a concern because of possible adverse health effects, including a reduction in fertility. A study performed at Harvard Medical School (HMS) in the United States by Maria Fernanda Hornos Carneiro and her research group shows that the harmful effects of BPA can be reversed by administering [...]

Os Spinels são óxidos com fórmulas químicas do tipo ABO 2 4, onde A é um cation divalent do metal (íon positivo), B são um cation trivalente do metal, e O é oxigênio. Os Spinels são avaliados para sua beleza, que se deriva das configurações espaciais das moléculas, mas os spinels em que o cation trivalente B consiste no cromo do elemento (Cr) despertaram o grande interesse para uma razão que [...]
