Nasopharyngeal carriage of Streptococcus pneumoniae among Brazilian children: Interplay with viral co-infection.

Nasopharyngeal transmission of Streptococcus pneumoniae is a prerequisite for the development of pneumococcal diseases. Previous studies have reported a relationship between respiratory viruses and S. pneumoniae infections.

Single-Step Deposition of Chalcopyrite (CuFeS) Thin Films.

Thin films of chalcopyrite, CuFeS, are promising candidates for use as absorber layers in photovoltaic cells due to their low band gap and high absorbance. These films are typically deposited in two or three steps, always involving an annealing process. In this work, the CuFeS film was deposited on a glass substrate in a single deposition step using the cathodic cylindrical plasma deposition (CCyPD) technique.

A Comparative Retrospective Study on Surgical Versus Conservative Treatment of Simple Fifth Metacarpal Neck Fractures.

Introduction The fifth metacarpal neck fracture is a common injury, and the treatment of such injuries is still a matter of debate. It typically presents in young adults of working age, and it represents a significant burden for both the health services and the patient. The purpose of this study was to compare the results of operative and conservative treatment of this fracture.

An Overview of Monkeypox Virus Detection in Different Clinical Samples and Analysis of Temporal Viral Load Dynamics.

Mpox is a zoonotic disease caused by the Monkeypox virus (MPXV), and since May 2022, tens of thousands of cases have been reported in non-endemic countries. We aimed to evaluate the suitability of different sample types for mpox diagnostic and assess the temporal dynamics of viral load. We evaluated 1914 samples from 953 laboratory-confirmed cases.

Hydromethanolic fraction from (Salicaceae) inhibits T24 bladder cancer cell line and the bacterium with high selectivity.

is a Brazilian species that has yet to be the subject of scientific investigation. However, it represents a potential source of new antibacterial and anticancer drugs, given it belongs to the Salicaceae family. The objective of this study was to investigate the potential biological activities and chemical composition of this species.
