Nurse participation in detecting signs of childhood autism in Primary Health Care.

Objectives: to understand nurse participation in the process of early detection of warning signs of autism spectrum disorders (ASD) in childcare consultations.

Methods: qualitative, exploratory research, conducted through semi-structured interviews conducted between August and November 2022 with 27 nurses from family clinics in the city of Rio de Janeiro. The IRaMuTeQ® software was used for data treatment.

Bioactivity of dressings based on platelet-rich plasma and Platelet-rich fibrin for tissue regeneration in animal model.

Background: Skin wounds are common injuries that affect quality of life and incur high costs. A considerable portion of healthcare resources in Western countries is allocated to wound treatment, mainly using mechanical, biological, or artificial dressings. Biological and artificial dressings, such as hydrogels, are preferred for their biocompatibility.

Changes in land uses caused by deforestation determine the arbuscular mycorrhizal fungi community composition in tropical environments.

Arbuscular mycorrhizal fungi (AMF) are obligate symbionts that help plants cope with biotic and abiotic stresses in soil ecosystems. However, AMF communities are highly sensitive to land use changes. In this study, we sampled soils from three environments (natural ecosystem, pasture, and deforested site) to characterize the AMF community (spores' abundance, richness, Shannon's diversity, and Simpson's dominance) and soil chemical properties (soil pH, soil organic carbon, available phosphorus, and total nitrogen).

UVA-light-induced mutagenesis in the exome of human nucleotide excision repair-deficient cells.

Skin cancer is associated with genetic mutations caused by sunlight exposure, primarily through ultraviolet (UV) radiation that damages DNA. While UVA is less energetic, it is the predominant solar UV component reaching the Earth's surface. However, the mechanisms of UVA-induced mutagenesis and its role in skin cancer development remain poorly understood.

Does viral circulation in slums have a global impact? The lesson learned from SARS-CoV-2 circulation in , Rio de Janeiro, Brazil.

Because of growing inequalities, more than one-third of the worldwide population is expected to live in slums by 2050. Although slum dwellers are at increased risk of infectious diseases, this population may have been overlooked with respect to the sustainability of virus evolution. In this study, we aimed to analyze the genetic diversity and evolution of SARS-CoV-2 in the slum, Rio de Janeiro, Brazil, and assess its impact on the global spread of the virus.
