Chip Mimicking Bovine Endometrium Used In Study Of Factors That Can Jeopardize Pregnancy
Publicado em 07 junho 2021
To investigate factors that can jeopardize pregnancy success in cattle, researchers at the University of São Paulo (USP) in Brazil used a kind of chip to mimic the environment of the endometrium, the tissue that lines the inside of the uterus.
The study was conducted by biologist Tiago Henrique Camara de Bem, a postdoctoral fellow at the University of São Paulo’s School of Animal Science and Food Engineering (FZEA-USP), in collaboration with four researchers at the [...]

Scientists use genetic engineering to explore mechanisms involved in psychiatric disorders
Publicado em 12 maio 2021Researchers used genetic engineering tools to create a virus that can enter specific neurons and insert into the prefrontal cortex a new genetic code that induces the production of modified proteins. In tests with mice, the alteration of these proteins was sufficient to modify brain activity, indicating a potential biomarker for the diagnosis of psychiatric disorders such as schizophrenia and autism. Sometimes referred to as the “executive brain,” the prefrontal cortex is the [...]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
