Newly Proposed Dose of Daclatasvir to Prevent Lethal SARS-CoV-2 Infection in Human Transgenic ACE-2 Mice.

Coronavirus disease 2019 (COVID-19) still causes death in elderly and immunocompromised individuals, for whom the sustainability of the vaccine response may be limited. Antiviral treatments, such as remdesivir or molnupiravir, have demonstrated limited clinical efficacy. Nirmatrelvir, an acute respiratory syndrome coronavirus 2 (SARS-CoV-2) major protease inhibitor, is clinically effective but has been associated with viral rebound and antiviral resistance.

Antioxidant activity, phytochemical composition, and antitumor capacity of Amazonian fruits taperebá (Spondias mombin) and murici (Byrsonima crassifolia).

The Amazon rainforest is renowned for its biodiversity and as a reservoir of edible and medicinal plants. The phytochemicals in murici and taperebá fruits serve as natural antioxidants, contributing to cultural preservation, ecosystem protection, and economic opportunities. However, limited scientific research on their composition and health benefits hinders their recognition as functional foods.

Evolution-based protein engineering: functional switching between transthyretins and 5-hydroxyisourate hydrolases.

Transthyretin (TTR) is a vertebrate-exclusive transport protein that plays a key role in binding and distributing thyroid hormones. However, its evolutionary origin lies in the duplication of the gene that encoding the enzyme 5-hydroxyisourate hydrolase (HIUase), which is involved in uric acid metabolism. Unlike TTR, HIUase is ubiquitous in both prokaryotes and eukaryotes, with the exception of hominids.

MonitoraSB: an innovation for monitoring and strengthening oral health in primary health care in Brazil.

Objective: This study describes the methodology used in the development of MonitoraSB, an innovation in the field of evaluating and monitoring oral health services in primary health care (PHC) in Brazil, and it discusses its characteristics and possible uses.

Methods: MonitoraSB includes a matrix of indicators and digital tools, developed in collaboration with oral health team dentists and oral health managers. The indicators evaluate the provision and management of oral health services and were developed on the basis of the model for evaluating the effectiveness of oral health care.
