Protein that detects light may play a role in the origin and progression of melanoma, study suggests
Publicado em 09 agosto 2022
Melanopsin (OPN4) is a light-emitting protein found in skin and retinal cells. A new study conducted at the University of São Paulo (USP) in Brazil shows that OPN4 can also be involved in the development of melanoma, the most serious type of skin cancer.
In experiments with animals and genetically modified cells in the Comparative Physiology of the Pigmentation Laboratory of the Institute of Biosciences (IB-USP), the researchers showed that the disease progresses slowly when this [...]

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 [...]ver notícia -
Highly abundant virus in humans could be a biomarker for COVID-19
Publicado em 05 novembro 2021Torquetenovirus (TTV) is one of the viruses most frequently found in the human organism. It is also common in monkeys and domestic animals. Its presence has not been associated with any known disease, but its excessive replication is a sign that something is wrong with the immune system. The correlation between high TTV load and immunosuppression has been used in medicine in certain contexts, such as monitoring transplant patients who take medication to prevent rejection of the transplanted [...]ver notícia -
Older people with abdominal fat develop mobility problems
Publicado em 01 setembro 2021Sao Paulo [Brazil], September 1 (ANI): A new study has found that the dangerous combination of weak muscles and abdominal fat can lead to a significant loss of gait speed in older people. The findings of the study were published in the journal 'Age and Ageing'. The study was conducted by researchers at the Federal University of Sao Carlos (UFSCar) in the state of Sao Paulo, Brazil, in partnership with colleagues at University College London (UCL) in the UK. A slower gait is a natural [...]ver notícia -
Older people with abdominal fat and weak muscles are more likely to develop mobility problems
Publicado em 31 agosto 2021Skeletal muscle and abdominal fat are a dangerous combination for older people who have difficulty walking. A study conducted by researchers at the Federal University of San Carlos (UFSCar) in Sao Paulo, Brazil, in collaboration with colleagues at University College London (UCL) in the United Kingdom, found that walking speed in the elderly was significantly reduced. Is shown. It has these two physical properties. slow walking This is a natural result of the aging process, but sudden slowdowns [...]ver notícia -
Transcranial stimulation enhances beneficial effect of aerobic exercise on gait in Parkinson’s patients, study finds
Publicado em 24 agosto 2021Transcranial direct current stimulation (tDCS) can enhance the effectiveness of aerobic exercise and improve gait in Parkinson’s patients immediately after the session. Step time variability is reduced, reaction time is shortened, and gait execution control is strengthened. These were the main findings of a 20-volunteer, randomized, double-blind, false-controlled crossover study by researchers at the Institute of Biological Sciences (IB-UNESP) at Sao Paulo State University in Rio Claro, [...]ver notícia -
Study refutes suspicion that dengue increases risk of microcephaly associated with Zika
Publicado em 20 julho 2021A Brazilian study comparing data from pregnant women in Rio de Janeiro and Manaus shows that pregnant women infected with Zika virus are not at increased risk of giving birth to a baby with microcephaly if they have previously been infected with dengue virus. .. The Zika epidemic occurred in Brazil in 2015-16. Dengue fever I have endemic disease. Both viruses are transmitted by Aedes aegypti. Some of the states affected by the Zika epidemic Microcephaly, A rare neuropathy in which the [...]ver notícia -
Novel coronavirus infects and replicates in salivary gland cells
Publicado em 07 julho 2021In Brazil, researchers at the University of São Paulo’s Medical School (FM-USP) have discovered that SARS-CoV-2 infects and replicates in the salivary glands. Analysis of samples from three types of salivary gland obtained during a minimally invasive autopsy procedure performed on patients who died from complications of COVID-19 at Hospital das Clínicas, FM-USP’s hospital complex, showed that tissues specializing in producing and secreting saliva serve as reservoirs [...]ver notícia -
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 region [...]ver notícia -
Physical activity reduces cardiovascular risk in rheumatic patients
Publicado em 27 abril 2021The risk of developing atherosclerosis—a narrowing of the arteries as cholesterol plaque builds up, leading to obstruction of blood flow—is higher for people with autoimmune rheumatic diseases than for the general population. As a result, they are more likely to have heart attacks and other cardiovascular disorders. The good news, according to a new study published in Rheumatology, is that regular exercise is a powerful weapon against vascular dysfunction in these patients. In the [...]ver notícia
