Protein that detects light may play role in origin and progression of melanoma
Publicado em 09 de agosto de 2022
Melanopsin (OPN4) is a light-sensing protein found in skin and retina cells. A new study conducted at the University of São Paulo (USP) in Brazil suggests that OPN4 can also participate in the development and progression of melanoma, the most aggressive type of skin cancer.
In experiments with animals and genetically modified cells at the Comparative Physiology of Pigmentation Laboratory belonging to the Institute of Biosciences (IB-USP), the researchers showed that the disease [...]

Study points to novel method of detecting complications caused by P. vivax in malaria patients
Publicado em 23 dezembro 2021In an article published in a journal eLifeResearchers at the University of Campinas (UNICAMP) in the state of Sao Paulo, Brazil, to detect imbalances and complications in patients infected with Plasmodium vivax, which is the cause of malaria and the main cause of the disease. Explains the new strategy. Americas. Studies show that total parasite biomass in patients is a better predictor of the degree of out-of-bloodstream infection than parasitemia, which is the number of live parasites in a [...]ver notícia -
Transcranial stimulation effective for aerobic exercise
Publicado em 25 agosto 2021Brasilia [Brazil], August 25 (ANI): Transcranial direct current stimulation (tDCS) can increase the benefits of aerobic exercise and improve the gait of patients with Parkinson's disease immediately after a session. Step time variability decreases, reaction time shortens, and executive control of gait is enhanced. These were the main findings of a randomized, double-blinded, sham-controlled crossover study of 20 volunteers by researchers at Sao Paulo State University's Institute of [...]ver notícia
