Low-cost biosensor test could extend reliable COVID-19 testing to remote and disadvantaged areas
Publicado em 13 maio 2021
A low-cost, rapid diagnostic test for COVID-19 developed by Penn Medicine provides COVID-19 results within four minutes with 90 percent accuracy. A paper published this week in Matter details the fast and inexpensive diagnostic test, called RAPID 1.0 (Real-time Accurate Portable Impedimetric Detection prototype 1.0). Compared to existing methods for COVID-19 detection, RAPID is inexpensive and highly scalable, allowing the production of millions of units per week.
Despite the urgency of the [...]

Study reveals factors that can make placenta less capable of protecting fetus from zika
Publicado em 28 outubro 2020Genetic factors that reduce the placenta’s capacity to protect the fetus from the zika virus are described by Brazilian researchers in an article published in PLOS Neglected Tropical Diseases. According to the authors, the findings help explain why only some babies whose mothers are infected by zika virus during pregnancy are born with some kind of anomaly. Since the 2015 epidemic at least 3,500 babies have suffered from zika congenital syndrome, which includes microcephaly, brain [...]ver notícia -
Study identifies key enzyme for development of autoimmune diseases
Publicado em 20 outubro 2020Scientists affiliated with the Center for Research on Inflammatory Diseases (CRID), hosted by the University of São Paulo (USP) in Brazil, have discovered that an enzyme involved in key metabolic processes also plays a role in immune cell differentiation and hence in the development of autoimmune diseases. The finding could contribute to the future development of new treatments and more cost-effective and resolutive medications for this kind of disease. The study is reported in the [...]ver notícia -
Oxytocin can help prevent osteoporosis
Publicado em 10 agosto 2020Oxytocin, produced by the hypothalamus and sometimes known as the “love hormone” for its involvement in pair bonding and orgasm, can be a strong ally in the control and prevention of osteoporosis, according to a study by scientists at São Paulo State University (UNESP) in Brazil. The study showed that when administered to female rats at the end of their fertile period, the hormone reversed precursors of osteoporosis, such as reduced bone density, decreased bone strength and [...]ver notícia -
Leukemia drug shows the potential to treat aggressive pediatric brain cancer
Publicado em 23 julho 2020Researchers affiliated with the University of São Paulo’s Ribeirão Preto Medical School (FMRP-USP) in Brazil have demonstrated the potential of a leukemia drug, arsenic trioxide, to treat medulloblastoma, a type of brain cancer most common in children. When they tested arsenic trioxide on cells taken from one of the most aggressive subgroups of this type of tumor, they obtained promising results in terms of tumor cell death. The drug also made the tumor cells more sensitive [...]ver notícia -
Experimental drug reduces replication of zika virus and prevents microcephaly in mice
Publicado em 22 julho 2020An international group of researchers have discovered that inhibiting AHR (aryl hydrocarbon receptor)—a protein with roles in regulating immunity, stem cell maintenance and cellular differentiation—enables the immune system to combat replication of zika virus in the organism far more effectively. In experiments performed at the University of São Paulo’s Biomedical Sciences Institute (ICB-USP) in Brazil, the antiviral therapy proved capable of preventing the development [...]ver notícia -
Leukemia Drug Shows the Potential to Treat Aggressive Paediatric Brain Cancer

When they tested arsenic trioxide on cells taken from one of the most aggressive subgroups of this type of tumour, they obtained promising results in terms of tumour cell death. The drug also made the tumour cells more [...]ver notícia -
Brazilian scientists develop COVID-19 accelerometer
Publicado em 24 junho 2020Researchers at São Paulo State University (UNESP) in Araçatuba, Brazil, have developed a computational tool that acts like a "COVID-19 accelerometer," plotting in real time the rate at which growth is accelerating or decelerating in more than 200 countries and territories. Available free of charge online, the application automatically loads the most recently notified case numbers from the European Center for Disease Prevention and Control (ECDC), updated daily, and [...]ver notícia
