Immunotherapy with house dust mite extract reduces symptoms of atopic dermatitis
Publicado em 04 fevereiro 2022
Treatment with house dust mite extract was found to be effective against signs and symptoms of atopic dermatitis (eczema), a chronic inflammatory disease that results in itchy, swollen and cracked skin. Researchers at the University of São Paulo’s Ribeirão Preto Medical School (FMRP-USP) in Brazil studied the effects of sublingual immunotherapy with extract of Dermatophagoides pteronyssinus, a ubiquitous dust mite, administered to patients in drops for 18 [...]

Respiratory disorders in obese people can be diagnosed early by examining cardiopulmonary exercise: A study
Publicado em 07 novembro 2021A new study has found that cardiopulmonary exercise testing (CPET) can be used for early detection of respiratory disorders in overweight and obese individuals. This is the main finding of a study by Brazilian researchers that set out to examine the influence of obesity on physiological responses obtained with CPET. The findings of the study were published in the journal ‘PLOS ONE’. Most of the authors are researchers in the Department of Human Movement Sciences at the Federal [...]ver notícia -
Scientists discover how forest fires influence rain cloud formation in the Amazon
Publicado em 27 outubro 2021A Brazilian study published in the journal Communications Earth & Environment shows how wildfires and forest burning for agriculture influence rain cloud formation in the Amazon. According to the authors, aerosols (tiny solid particles and liquid droplets emitted into the atmosphere by fire) hinder the freezing of cloud droplets when the atmosphere is humidified, but can also promote freezing when the atmosphere is dry. This alters the natural functioning of clouds and their typical height, [...]ver notícia -
Monitoring viruses, fungi and bacteria can prevent new pandemics
Publicado em 28 setembro 2021A pandemic covid-19 made clearer the need for the so -called sentinel system, which monitors pathological agents to avoid outbreaks or even predict future epidemics. In addition to viruses such as Sars-CoV-2, however, it is also important to monitor fungi and bacteria that have not yet been effectively treated and can spread. This is the theme of the 4th FAPESP 60th Anniversary Conference, “Global Health Challenges”. The event was moderated by Helena Nader, professor at the [...]ver notícia -
The aquatic fungus that has killed many amphibian species now threatens landfills, study says
Publicado em 16 setembro 2021A water fungus that has led to the extinction of many species of amphibians with part or all of their life in water also threatens terrestrial frogs. A team of researchers supported by FAPESP found in the Atlantic Forest an unprecedented mortality rate of frogs developing far from the aquatic environment. Amphibians are infected with a high load of chytrid fungus (Batrachochytrium dendrobatidis), caused by chytridiomycosis. The studying, published in the magazine Biological [...]ver notícia -
Covid afeta os testículos, reduz a qualidade do hormônio e do esperma, mostram estudos
Publicado em 03 setembro 2021Seguindo, desde o ano passado, pacientes do sexo masculino tiveram covid-19, do andrologista Jorge Hallak, professor da Faculdade de Medicina de Universidade de São Paulo, começaram a notar que os resultados de seus testes hormonais e de fertilidade permaneceram inalterados por muitos meses após a recuperação da doença. Apesar de um teste preliminar e de não ser capaz de diagnosticar fertilidade ou infertilidade, a contagem de [...]ver notícia -
The newly discovered cell type makes sepsis survivors more vulnerable to infections
Publicado em 02 setembro 2021Sepsis is the leading cause of death of Brazil’s intensive care units (ICUs). Among patients progressing to the acute form of the disease, 40% die, and survivors often suffer from cardiovascular and neurological complications, as well as a significant decline in immunity that lasts for many years. after they were discharged from the hospital. "Studies suggest that sepsis survivors face a seven times higher risk of developing a severe infection than individuals who have never had the [...]ver notícia -
The first genetic sequencing of the Brazilian pit viper has been completed
Publicado em 16 agosto 2021A team led by researchers at the Butantan Institute and funded by the São Paulo Research Foundation-FAPESP has completed the first genome sequencing of a snake in Brazil. The study was reported in an article published in the journal PNAS. This suggests that the nine genes that encode the toxins produced by the jararaca pit viper The samerops jararaca may have been derived from genes that had different functions in the ancestral species. “In sequencing the snake genome, we [...]ver notícia -
A variante gama é mais agressiva do que a cepa original do vírus Covid-19, mas contém vacina e bloqueio, diz o estudo
Publicado em 08 agosto 2021RIO – Pesquisa mostra que a prevalência da variante Gama (P.1) foi responsável por aumento significativo de casos graves (127%) e óbitos (162%) nos meses de março e abril de 2021, no município de São José do Rio Preto (SP), mas essa vacinação e o bloqueio de 15 dias mitigaram seus danos. O estudo foi publicado na plataforma medRxiv, mas sem revisão por pares. – Essa é a conclusão esperada, mas eles [...]ver notícia -
A variante gama é mais agressiva, mas pode incluir vacinação e lockdown
Publicado em 06 agosto 2021Ao relacionar dados de sequência genômica e análises epidemiológicas na cidade de São José do Rio Preto (SP), os pesquisadores conseguiram demonstrar o impacto da proliferação da variante P.1 (denominada Gamma) na liberação de casos e óbitos do COVID-19. A maior transmissibilidade dessa cepa esteve associada ao aumento significativo de casos graves (127%) e óbitos (162%) nos meses de março e abril de 2021, [...]ver notícia
