Bacteria that cause periodontitis are transmitted from parents to children
Publicado em 15 abril 2021
Adults with periodontitis transmit bacteria that can cause the disease in future to their children, and the bacteria remain in the oral cavity even when the children undergo treatment of various kinds, reinforcing the need for preventive care in the first year of a baby's life. This is the main conclusion of a study conducted at the University of Campinas (UNICAMP) in the state of São Paulo, Brazil. An article on the study is published in Scientific Reports.
Periodontitis is an [...]

Study shows why crossing obstacles is difficult for patients with Parkinson's disease
Publicado em 08 abril 2021A multidisciplinary research group affiliated with the Department of Physical Education's Human Movement Laboratory (Movi-Lab) at São Paulo State University (UNESP) in Bauru, Brazil, measured step length synergy while crossing obstacles in patients with Parkinson's disease and concluded that it was 53% lower than in healthy subjects of the same age and weight. Step length is one of the main variables affected by the disease. Synergy, defined as combined operation, refers in this [...]ver notícia -
A technique to produce transplantable livers in the laboratory
Publicado em 06 abril 2021Researchers at the Human Genome and Stem Cell Research Center (HUG-CELL), hosted by the University of São Paulo's Institute of Biosciences (IB-USP) in Brazil, have developed a technique to reconstruct and produce livers in the laboratory. The proof-of-concept study was conducted with rat livers. In the next stage of their research, the scientists will adapt the technique for the production of human livers in order in future to increase the supply of these organs for [...]ver notícia -
High-fiber diet may play a role in controlling the inflammation associated with COVID-19
Publicado em 31 março 2021A study conducted at the University of Campinas (UNICAMP) in the state of São Paulo, Brazil, shows that compounds produced by gut microbiota (bacteria and other microorganisms) during fermentation of insoluble fiber from dietary plant matter do not affect the ability of the novel coronavirus SARS-CoV-2 to enter and replicate in cells lining the intestines. However, while in vitro treatment of cells with these molecules did not significantly influence local tissue infection, it reduced [...]ver notícia -
Arsenal used by parasite to affect cellular defense and enhance leishmaniasis is revealed
Publicado em 23 março 2021Researchers have succeeded in revealing the arsenal used by protozoans of the genus Leishmania in human cells to make leishmaniasis more severe, especially in cases of the mucocutaneous variety of the disease, which can cause deformations in patients. The discovery points the way to a search for novel treatments for the disease as well as casting light on a key mechanism involved in other diseases. The mechanism involves Leishmania, macrophages and a virus that lives endosymbiotically in the [...]ver notícia -
Study could help develop biosensors for non-invasive diagnosis of diseases
Publicado em 22 março 2021The efficacy of biosensors used in clinical tests depends critically on the surface of the device on which the biorecognition molecules are immobilized. This surface can be adjusted and sometimes controlled using self-assembled molecular monolayers as matrices. The monolayers are films made up of organic molecules that under the right conditions assemble spontaneously on metal surfaces via chemical bonds between the sulfur atoms and the metal. A study conducted at the University of São [...]ver notícia -
Study finds inflammatory mechanism responsible for bone erosion in rheumatoid arthritis
Publicado em 18 março 2021In a study aimed at investigating the mechanism responsible for exacerbating rheumatoid arthritis in smokers, researchers at the Center for Research on Inflammatory Diseases (CRID), linked to the University of São Paulo (USP) in Brazil, discovered a novel path in the inflammatory process associated with the bone damage caused by rheumatoid arthritis. The discovery opens up opportunities for new therapeutic interventions to mitigate the effects of the disease, for which there is no [...]ver notícia -
Scientists assess effects of soccer player preparation and recovery on kicking performance
Publicado em 17 março 2021Brazilian researchers have published a systematic review of the scientific literature showing that some warm-up strategies such as dynamic stretching can effectively prepare soccer players to maintain kicking accuracy, whereas intense physical exercises have a negative effect on the velocity of the ball when kicked, and consumption of carbohydrate beverages during a match can enable players to maintain adequate kicking performance in the concluding moments of prolonged physical exercise such as [...]ver notícia -
Molecule with potential to treat multiple sclerosis passes toxicology testing in zebrafish
Publicado em 09 março 2021Brazilian researchers who study a native venomous fish have confirmed a route to drug development for the treatment of chronic inflammatory diseases such as multiple sclerosis and asthma. The venomous toadfish Thalassophryne nattereri contains a peptide (TnP) with anti-inflammatory and anti-allergic potential. Confirmation of this potential has now come via the zebrafish Danio rerio, a popular aquarium species native to South Asia that shares 70% of its genome with humans and is widely used as [...]ver notícia -
Innovative cancer treatment found to be promising for the control of fungal infections
Publicado em 05 março 2021The use of CAR T-cells reprogrammed to “recognize” Cryptococcus spp. proved effective to combat the infection in vitro and in mice (pulmonary cryptococcosis; image: Wikimedia Commons) An innovative cell-based treatment for cancer has been found promising for the control of infections caused by fungi. A study published in the journal Cytotherapy reports that the use of chimeric antigen receptor (CAR) T-cells programmed to recognize Cryptococcus spp. fungi was effective in [...]ver notícia
