Antibacterial and Antioxidant Properties of Geopropolis Extracts from Stingless Bees (Meliponinae) Occurring in Brazilian Territory.

This study focuses on exploring the biological properties, antioxidant and antibacterial  associated with geopropolis resin extracts produced in Brazil. Searches were performed in the electronic databases: Lilacs, Medline, PubMed, Scielo and Science Direct. Fifteen (15) experimental studies were selected as compatible with the objective of this systematic review.

Microbiome modulation of implant-related infection by a novel miniaturized pulsed electromagnetic field device.

Dental implant-related infections, which lack effective therapeutic strategies, are considered the primary cause for treatment failure. Pulsed electromagnetic field (PEMF) technology has been introduced as a safe and effective modality for enhancing biological responses. However, the PEMF effect on modulating microbial diversity has not been explored.

Sample Preparation Approaches for Determination of Quinolones in Aqueous Matrixes: Systematic Review.

Quinolones and fluoroquinolones are among the most used antibiotics worldwide. Antibiotic resistance genes can be acquired by human pathogens from ambient microorganisms, which can lead to a treatment failure for bacterial infections. Furthermore, determining the levels of quinolones and fluoroquinolones in aqueous matrixes is crucial for safeguarding both human health and the environment.

Analysis of noninvasive methods in chronic hepatitis/human immunodeficiency virus mono- and co-infected patients with advanced fibrosis.

Objectives: The aim of this study was to evaluate the degree of advanced fibrosis (F3/F4) using noninvasive methods [elastography, Fibrosis-4 (FIB4), and aspartate aminotransferase to platelet ratio index (APRI)] before and after treatment with new direct-acting antiviral agents (DAAs) in patients with hepatitis C virus (HCV), both in cases of co-infection (HCV/HIV) and single infection (HCV).

Methods: This is a longitudinal study involving patients with HCV who are co-infected with HIV, who initiated HCV treatment between a positive anti-HCV test for more than 6 months and detectable HCV RNA. The control group consisted of patients with HCV infection without HIV co-infection, who received treatment during the same period as the co-infected patients.

Reassessing the link between adiposity and head and neck cancer: a Mendelian randomization study.

Background: Adiposity has been associated with an increased risk of head and neck cancer (HNC). Although body mass index (BMI) has been inversely associated with HNC risk among smokers, this is likely due to confounding. Previous Mendelian randomization (MR) studies could not fully discount causality between adiposity and HNC due to limited statistical power.
