Protein with anti-aging action combats inflammation and avoids death of neurons
Publicado em 07 de fevereiro de 2023
The process of cellular aging is multifactorial, and its investigation involves several knowledge areas. Finding ways to protect cells against damage is a key focus. A group of researchers recently achieved noteworthy progress in this regard, as evidenced by an article published in Scientific Reports, a Springer Nature journal. According to the authors, in their study, the protein klotho protected glial cells against inflammation and death. Glia are non-neuronal cells of the brain and nervous [...]

Study links genetic variant to digestive disturbances in patients with Chagas disease
Publicado em 06 dezembro 2022Chagas disease, caused by the protozoan parasite Trypanosoma cruzi, affects some 8 million people worldwide. More than a third develop severe heart or digestive problems with a heightened risk of death. The process that leads to this clinical condition is not completely understood. An article published in the journal Biomedicines describes a study led by Brazilian researchers showing that mutations occurred in the mitochondrial genes of patients with Chagas disease megaesophagus, a disorder [...]ver notícia -
Novel device detects COVID-19 antibodies in five minutes
Publicado em 30 novembro 2022Rapid, cheap and accurate tests continue to be essential for epidemiological surveillance and for health services to monitor and contain the spread of SARS-CoV-2. Brazilian scientists have contributed to endeavors in this field by developing an electrochemical immunosensor that detects antibodies against the virus. The innovation is described in an article published recently in the journal ACS Biomaterials Science and Engineering. In search of a novel diagnostic method, the group opted for a [...]ver notícia -
Artificial intelligence helps detect gait alterations and diagnose Parkinson’s disease
Publicado em 23 novembro 2022Scientists affiliated with the Department of Physical Education’s Human Movement Laboratory (Movi-Lab) at São Paulo State University (UNESP) in Bauru, Brazil, are using artificial intelligence to help diagnose Parkinson’s disease and estimate its progression. An article published in the journal Gait & Posture reports the findings of a study in which machine learning algorithms identified cases of the disease by analyzing spatial and temporal gait parameters. The [...]ver notícia -
Scientists Discover That a Certain Nutrient Promotes Anti-Aging
Publicado em 08 setembro 2022According to a clinical trial involving 55 to 70-year-old women, adding this nutrient to the diet can strengthen the body’s antioxidant defenses and possibly lower the chance of developing diabetes, high blood pressure, and cardiovascular disease. However, more research is needed to confirm its effect. According to the study, the amino acid taurine could be employed in anti-aging therapies. Our cells produce potentially toxic by-products known as “free radicals” when [...]ver notícia -
Study finds link between post-COVID loss of smell or taste and memory problems
Publicado em 18 agosto 2022FUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO Studies conducted before the COVID-19 pandemic showed that loss of smell could be an early sign of the impending onset of Alzheimer’s disease. There is evidence in the scientific literature that this sensory disorder may appear years before the first cognitive symptoms, suggesting a link between the brain regions responsible for memory and for interpreting olfactory stimuli. This hypothesis has recently [...]ver notícia -
Lack or excess of amino acid methionine in diet can affect liver cells, study shows
Publicado em 16 junho 2022Having shown that diet can influence gene expression, science is starting to find out more about how this happens. According to an article recently published in Food and Chemical Toxicology, a diet supplemented with or deficient in methionine, an essential amino acid abundant in eggs, meat and seafood, affects the expression of genes associated with liver cell fat metabolism and genes that modify chromatin, the coiled fibers made up of DNA and proteins that form chromosomes in cells. The [...]ver notícia -
Peptide delays melanoma growth in animal trials
Publicado em 23 maio 2022An article published in Scientific Reports describes a study demonstrating the effectiveness of a peptide developed by Brazilian scientists, called Rb4, in combating cancer progression in an animal model, especially malignant melanoma. The molecule holds promise for the treatment of drug-resistant tumors. Preclinical in vitro and in vivo trials indicated that Rb4 triggers necrosis in murine melanoma cells, and inhibits the viability of human cancer cells. Tumor cells in the study lost the [...]ver notícia -
Study presents novel therapeutic target for treatment of sepsis
Publicado em 13 janeiro 2022A new strategy for preventing complications associated with sepsis is presented by researchers affiliated with the University of São Paulo (USP) and collaborators in an article published in the journal Blood. The proposal is to inhibit the action of a protein called gasdermin D, which the authors show is possible with disulfiram, a drug already approved for human use and originally indicated to combat alcohol dependence. The study was conducted at the Center for [...]ver notícia -
Heparin dose capable of preventing COVID-19 deaths is four times higher than the dose recommended by WHO
Publicado em 29 outubro 2021The anti-coagulant heparin reduces the likelihood of death from COVID-19 by 78% when administered in therapeutic doses to patients with signs of respiratory failure on admission to hospital, according to a study reported on October 14 in the British Medical Journal. The World Health Organization (WHO) currently recommends only prophylactic use of heparin for such patients. The prophylactic dose of the drug, prescribed mainly to prevent blood clots, is only a quarter of the therapeutic dose. [...]ver notícia
