Inflammation in pregnancy can cause cleft lip in babies with genetic predisposition
Publicado em 27 junho 2023Researchers from the University of São Paulo (USP) and University College London, in the United Kingdom, demonstrated in an animal model that cleft lip and palate, a condition also known as cleft lip, is due to the association of two factors: one. genetics and others associated with the occurrence of inflammation during pregnancy – in the period of formation and development of the embryo. in an article published in the magazine Nature of Communication, the group describes how [...]ver notícia -
Discoveries about adipose tissue hormone function open new avenues for treating obesity
Publicado em 27 junho 2023June 27, 2023 by newsy today Data published by the World Health Organization (WHO) in 2022 indicate that more than one billion people in the world are obese. Adiponectin, a type of hormone released by adipose tissue, has a double important role in preserving pancreatic function: in thin people, it protects beta cells, which are responsible for insulin secretion; and, in people with obesity, it reverses the damage that has been established in this tissue. The discovery was made by researchers [...]ver notícia -

Researchers from the University of São Paulo (USP), in collaboration with the University College London, from the United Kingdom, managed to prove in an animal model that cleft lip and palate, also known as cleft lip, occurs as a result of the association. in two events: one genetic and another caused by inflammation [...]ver notícia -
Brazilians advanced in understanding the physics behind stellar superexplosions
Publicado em 23 junho 2023José Tadeu Arantes FAPESP agency – The relationship between sunspots and solar flares has been extensively investigated in the study of the Sun. Especially because these eruptions associated with coronal mass ejections, where large amounts of energy are released, directly affect our planet, causing a greater occurrence of aurora borealis; blackout in radio communication; increase the effect of jitter on the GPS signal; reduction in speed and altitude of artificial satellites ( Read [...]ver notícia
