Terpyridine-based ruthenium complexes containing a 4,5-diazafluoren-9-one ligand with light-driven enhancement of biological activity.

There has been growing effort in the scientific community to develop new antibiotics to address the major threat of bacterial resistance. One promising approach is the use of metal complexes that provide broader opportunities. Among these systems, polypyridine-ruthenium(II) complexes have received particular attention as drug candidates.

Antibiotic Residues in Raw Cow's Milk: A Systematic Review of the Last Decade.

The inappropriate use of antimicrobials in dairy animals can lead to residues in raw milk and in dairy products. Foods containing residues of this nature, whether in the short, medium, or long term, cause serious health harm. Absence of these compounds in foods should be a premise for declaring safety.

Entomological investigation after an outbreak of dengue at the riverside of Rio Doce, Espírito Santo State, Brazil.

Background: In 2019, a dengue outbreak involving Aedes albopictus occurred in a rural area of Espírito Santo, Brazil, motivating our study in Sooretama and Linhares.

Methods: We set traps to sample immature mosquito larvae at 40 sites, with weekly inspections from July 2022 to January 2023. Adult specimens were collected monthly at 19 sites, each collection lasting 15 min.

Trends in Mortality Due to Stroke in South America between 1990 and 2019.

Stroke is the second leading cause of death and disability in Latin America; however, few epidemiological studies have been conducted in South America. An observational study was conducted to analyze trends in stroke mortality in South American (SA) countries. Age-standardized mortality rates and proportional mortality due to stroke in the populations of SA countries between 1990 and 2019 were assessed by extracting data from the Global Burden of Disease 2019 study.

The journey of stage III and IV non-small cell lung cancer patients in the Brazilian private healthcare system: a retrospective study.

Non-small cell lung cancer (NSCLC) is still diagnosed at late stages in Brazil. The availability of newer treatment options has changed patient management, however, few real-world data have been published since then. This is a population-based retrospective cohort study that aims to evaluate the characteristics of stage III/IV NSCLC patients and their journey in the Brazilian private healthcare system.
