Brazilian scientists propose conducting experiments using mini-brains grown in the laboratory to study the effect of drugs on fetal brain development.
Depression affects a significant proportion of pregnant women worldwide, with an estimated 10% to 16%. While most women can improve with antidepressants, the effects of these drugs on fetal brain development are not fully understood.
Brazilian researchers reviewed more than 100 scientific articles on the topic and concluded that advanced [...]

Experiments Show Infection of Visceral Fat Cells May Contribute to Severe COVID-19
Publicado em 20 dezembro 2022Two types of adipocytes (fat cells) were infected in the laboratory: one obtained from human stem cells isolated from subcutaneous tissue and the other differentiated from stem cells taken from visceral fatty tissue. Experiments show that visceral fat – fat around the liver, intestines, and other organs, considered a risk factor for cardiovascular disease, diabetes, and high blood pressure – contributes more to severe COVID-19 than subcutaneous fat (under the skin, as in [...]ver notícia -
Artificial intelligence helps Brazilian breeders select desired traits of native fish
Publicado em 16 dezembro 2022If you look at a net full of pacus (Piaractus mesopotamicus), you cannot distinguish with the naked eye which individuals will have descendants with higher filet yield or faster weight gain. Their growth can be monitored with a tape measure, and they can be weighed on a scale. The data can be tabulated and compared. But to breed an entire population with the right characteristics, some 2,000 fish per generation must be measured and weighed, and the task can take days. In Brazil, [...]ver notícia
