Study reveals how novel coronavirus manipulates cells to replicate
Publicado em 19 de julho de 2022
An article published in the journal Frontiers in Cellular and Infection Microbiology reports a study by researchers at the State University of Campinas (UNICAMP) and the University of São Paulo (USP) in Brazil showing how a human protein interacts with a SARS-CoV-2 protein, and describing one of the ways the virus that causes COVID-19 recruits cells to replicate.
In laboratory tests, the researchers inhibited interaction between the molecules using a drug and thereby reduced viral [...]

Study shows that 8% of athletes have persistent symptoms after contracting COVID-19
Publicado em 08 julho 2022Newswise — Researchers at the University of São Paulo (USP) in Brazil analyzed data from 43 scientific articles describing the effects of COVID-19 on athletes and concluded that while the disease was asymptomatic or mild in the vast majority of cases (94%), about 8% of the subjects concerned had persistent symptoms affecting their performance and potentially preventing a return to training and competing. The data they analyzed referred to some 11,500 athletes, including amateurs [...]ver notícia -
How the Pandemic and Social Distancing Have Changed Our Perception of Time
Publicado em 28 junho 2022Newswise — The COVID-19 pandemic has changed the way people perceive the passage of time, according to an article published in the journal Science Advances. At the end of the first month of social distancing, in May 2020, most participants in the study (65%) reported feeling time was passing more slowly. The researchers classified this perception as “time expansion” and found it to be associated with feelings of loneliness and a lack of positive experiences [...]ver notícia -
Cold temps may help to combat obesity and related metabolic diseases by reducing inflammation, researchers find
Publicado em 27 junho 2022Newswise — BOSTON – More than 40 percent of American adults have obesity, a complex condition that can increase the risk of diabetes, cardiovascular disease and certain cancers. One mechanism by which obesity can lead to other health problems is by causing low-grade chronic inflammation, the accumulation of immune cells in insulin-sensitive tissues. Scientists hypothesize that reversing – known as resolving – this chronic inflammation could prevent the onset of [...]ver notícia -
Molecule that combines three distinct technologies against most aggressive type of brain cancer is tested
Publicado em 14 junho 2022Newswise — A drug carrier able to reach the brain, bind to an aggressive type of tumor called glioblastoma multiforme, and release a chemotherapeutic agent has been tested for the first time by Brazilian researchers. According to an article published in the International Journal of Pharmaceutics, the potential treatment was shown to be effective in isolated cells and animal models thanks to a combination of nanotechnology, chemotherapy and a monoclonal antibody. Glioblastoma multiforme [...]ver notícia -
Dwarf planet Ceres was formed in coldest zone of Solar System and thrust into Asteroid Belt
Publicado em 19 maio 2022Newswise — In an article published in the journal Icarus, researchers at São Paulo State University (UNESP) and collaborators report the findings of a study reconstituting the formation of the dwarf planet Ceres. The research was conducted by Rafael Ribeiro de Sousa, a professor in the program of graduate studies in physics on the Guaratinguetá campus. The co-authors of the article are Ernesto Vieira Neto, who was Ribeiro de Sousa’s PhD [...]ver notícia -
Gene therapy reverses effects of autism-linked mutation in brain organoids
Publicado em 02 maio 2022In a study published May 02, 2022 in Nature Communications, scientists at University of California San Diego School of Medicine used human brain organoids to reveal how a genetic mutation associated with a profound form of autism disrupts neural development. Using gene therapy tools to recover the gene’s function effectively rescued neural structure and function. Several neurological and neuropsychiatric diseases, including autism spectrum disorders (ASD) and schizophrenia have been [...]ver notícia -
SARS-CoV-2 can remain active for longer than recommended quarantine period, study shows
Publicado em 27 janeiro 2022Newswise — In a 38-year-old man who manifested mild symptoms of COVID-19 for 20 days, the novel coronavirus continued to be detected in his organism and to undergo mutations for 232 days. If he had not been given continuous medical care, maintained social distancing and worn a mask, he could have spread the virus throughout these seven months. The atypical case of infection by SARS-CoV-2 was part of a study involving 38 Brazilian patients followed on a weekly basis between April and [...]ver notícia -
SARS-CoV-2 may stay active longer than recommended quarantine period, study finds
Publicado em 27 janeiro 2022Newswise — In a 38-year-old man who had mild symptoms of COVID-19 for 20 days, the novel coronavirus continued to be detected and mutated in his body for 232 days. Had he not received ongoing medical care, maintained social distancing and worn a mask, he could have spread the virus throughout those seven months. The atypical case of SARS-CoV-2 infection was part of a study of 38 Brazilian patients followed weekly between April and November 2020 by researchers affiliated with the [...]ver notícia -
A conservation incentive yields increase of protected Atlantic Rainforest areas, but with limited results
Publicado em 03 dezembro 2021Newswise — A study by the University of São Paulo (USP) in Brazil investigated a fiscal transfer mechanism whereby states transfer part of their sales tax revenue to municipalities in exchange for the creation of environmental conservation units. The mechanism is known as ICMS-E. ICMS is state-collected sales tax, and the “E” stands for ecological. published in the journal Ecological Economics, the researchers show that although the fiscal transfer mechanism has [...]ver notícia
