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 [...]

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 test the technology. The [...]

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 [...]

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, [...]

People who approach the front desk at Albert Einstein Jewish Hospital (HIAE) in the city of São Paulo have their temperature taken remotely by a computer vision system installed in a nearby column. Consisting of a thermal camera and armed with facial recognition algorithms, the system scans people's face and measures their temperature automatically. If the system detects a fever, one of the symptoms of COVID-19, its artificial intelligence (AI) software sends a smartphone alert to [...]

Agência FAPESP – Highly concentrated aqueous electrolytes, known as water-in-salt electrolytes, could be an alternative to the organic solvents used in car batteries and other electrochemical devices. Abundance and, hence, low cost are key factors in this application, alongside nontoxicity, according to the review article “Water-in-salt electrolytes for high voltage aqueous electrochemical energy storage devices” published in the journal Current Opinion in [...]

On 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 [...]

Researchers at the Federal University of São Carlos (UFSCar) in Sorocaba (state of São Paulo, Brazil) have developed a technique to diagnose early-stage multiple sclerosis, a disease of the central nervous system, and distinguish it from neuromyelitis optica, a rare yet severe autoimmune inflammatory process also affecting the central nervous system. The immune system of a person with these diseases produces antibodies that attack and damage part of the myelin sheath, an [...]

Gluten is enemy No. 1 for those with celiac disease, and it's hard to avoid. Episodes of this chronic autoimmune illness can be triggered by ingesting gluten, a key protein in wheat and some other grains. Researchers have been exploring how gut bacteria, especially Bifidobacteria, could be used as a treatment. Now, scientists publishing the results of laboratory experiments in ACS' Journal of Agricultural and Food Chemistry report how specific types of Bifidobacteria work. Humans have [...]
