USP study identifies genes that protect from severe infection by covid
Publicado em 05 de outubro de 2022
Two studies recently published by Brazilian scientists help to understand genetic factors that protect some people from infection or even from developing the severe form of covid-19. One of the studies was carried out with a group of elderly people over 90 years old who are resistant to Sars-CoV-2 and the other describes the case of identical twins with a different outcome for the so-called long covid.
Since 2020, researchers from several countries, including Brazil, have sought to identify [...]

Cancer therapy shows potential to treat severe cases of covid
Publicado em 27 setembro 2022Study published in the journal Science Advances suggests that a type of treatment known as an inhibitor of checkpoint immunological – already used against certain types of cancer – may be beneficial in some severe cases of Covid-19. The creators of this type of therapy, which has the ability to reactivate the immune system, won the Nobel Prize in Medicine in 2018. The conclusions of the article are based on experiments carried out with cells from patients who had to be admitted [...]ver notícia -

New Hope. Drug proves to be effective in the treatment of severe Covid
Publicado em 16 setembro 2022A group of researchers from the University of São Paulo (USP), in Brazil, suggests that niclosamide, an antiparasitic used in the treatment of intestinal infections caused by the tapeworm parasite (solitary worm), may be an effective ‘weapon’ in the treatment of severe cases of infection by Covid-19, says a study published in the journal Science Advances. The drug is on the World Health Organization’s List of Essential Medicines. In the laboratory, it has shown [...]ver notícia -
Drug shows potential to fight inflammation associated with Covid
Publicado em 15 setembro 2022Experiments with animals and human cells carried out at the University of São Paulo (USP) suggest that niclosamide, an already widely usedvermifuge, would have antiviral action and could inhibit the exacerbated inflammatory response that often leads to death in patients with the severe form of Covid. -19.Further studies are still needed to find out whether the effects, described in an article in the journal Science Advances, are confirmed in humans. And, according to the authors, for [...]ver notícia -
Brazilians discover how the covid virus alters the rna of infected cells
Publicado em 13 setembro 2022For the first time, scientists from the Federal University of São Paulo (Unifesp) were able to show that infection with the SARS-CoV-2 virus, which causes Covid-19, alters the functioning pattern of cell RNAs. To do this, they examined 13 datasets obtained over four studies that analyzed viral RNA as well as that from animal and human cells. The most recent one, published in the magazine Frontiers in Cellular and Infection Microbiology, examined the epitranscriptome of Vero cells [...]ver notícia -
Fungal infections also played a role in the covid
Publicado em 13 setembro 2022Every day we inhale thousands of potentially pathogenic fungal spores, but our immune system simply eliminates them. However, in people whose immunity is compromised – transplant recipients, patients undergoing cancer treatment or hospitalized in Intensive Care Units (ICU) −, this interaction between pathogens and hosts can be quite different. (Read Polio State of Emergency Declared in New York) An example of this is the cases of fungal infections that emerged during the covid-19 [...]ver notícia -
New method can help predict cases of Covid
Publicado em 09 setembro 2022Researchers from Joint Brazil-UK Center for Arbovirus Discovery, Diagnosis, Genomics and Epidemiology (CADDE) developed a faster and less expensive method to analyze population serological data that can contribute to the assessment and prediction of the epidemiological behavior of Covid-19. The scientists demonstrated that the methodology was able to predict the transmission of the delta variant (detected in India in 2020 and originally called B.1.617.2) in Brazil. Now they are looking to [...]ver notícia -

The profession that suffered the most to reconcile work and family in Covid
Publicado em 31 agosto 2022At the beginning of the Covid-19 pandemic, in 2020, the remote modality required rapid reorganization in the work-family relationship. Research on the subject conducted at the Federal University of São Carlos (UFSCar) was awarded in a national contest for scientific articles promoted by the Coordination for the Improvement of Higher Education Personnel (Capes). The research that gave rise to the winning article is part of the doctoral project of Marcela Alves Andrade, a student in the [...]ver notícia
