Innovative cancer treatment found to be promising for the control of fungal infections
Publicado em 05 março 2021
An innovative cell-based treatment for cancer has been found promising for the control of infections caused by fungi. A study published in the journal Cytotherapy reports that the use of chimeric antigen receptor (CAR) T-cells programmed to recognize Cryptococcus spp. fungi was effective in combating infection in vitro and in mice.
C. gattii and C. neoformans are present in soil with dead organic matter and places contaminated by the droppings of pigeons and other birds. They cause systemic [...]

Researchers develop 10-minute COVID-19 diagnostic test that wage workers can afford
Publicado em 03 fevereiro 2021A test that detects antibodies to the novel coronavirus in 10 minutes and costs only a fifth of the market average has been developed by researchers at the University of São Paulo’s São Carlos Chemistry Institute (IQSC-USP) and Brazilian startup Biolinker, with São Paulo Research Foundation—FAPESP’s support. The device works similarly to the rapid tests available now in pharmacies. It analyzes a drop of blood, and two red LEDs light up if it detects the [...]ver notícia -
Why it is harder for Brazilians of African descent to find bone marrow donors
Publicado em 02 fevereiro 2021A paper by a multidisciplinary team of scientists affiliated with various Brazilian institutions, including the University of São Paulo (USP) and the National Cancer Institute (INCA), shows that people of African descent are less likely to find a donor in the National Register of Voluntary Bone Marrow Donors (REDOME) than people with predominantly European ancestry. The paper is published in Frontiers in Immunology. REDOME is the world’s third-largest bone marrow bank, with more [...]ver notícia -
Melatonin produced in the lungs prevents infection by novel coronavirus
Publicado em 28 janeiro 2021Melatonin synthesized in the lungs acts as a barrier against SARS-CoV-2, preventing expression of genes that encode proteins in cells such as resident macrophages in the nose and pulmonary alveoli, and epithelial cells lining the alveoli, all of which are entry points for the virus. The hormone, therefore, prevents infection of these cells by the virus and inhibits the immune response so that the virus remains in the respiratory tract for a few days, eventually leaving to find another [...]ver notícia -
Atrophy can be combated by boosting expression of an enzyme produced in muscles
Publicado em 06 novembro 2020Researchers at the University of São Paulo (USP) in Brazil have shown for the first time that stimulating expression of a protein naturally produced by the human body can be a strategy to combat loss of skeletal muscle mass, which happens normally with aging but can intensify in cases of neurodegenerative or inflammatory disease, or in patients who spend long periods in intensive care units (ICUs). Ten days in an ICU are estimated to result in the loss of up to 20% of muscle mass in the [...]ver notícia -
Study reveals factors that can make placenta less capable of protecting fetus from zika
Publicado em 27 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 -
Community health workers could play a key part in combating COVID-19 in Brazil, study says
Publicado em 07 outubro 2020Brazil has more than 286,000 community health workers integrated into the national primary healthcare program. These professionals form a broad network serving 75% of the population, especially low-income families who lack medical insurance and are the most adversely affected by the COVID-19 pandemic. “Back in March, researchers at Imperial College London noted Brazil’s network of community health workers as a valuable asset that could assure an effective response to the pandemic.
