Human Health Risk Assessment From Exposure to Toxic Metals in Soils and Leafy Vegetables in Smallholder Farms of Northeastern Brazil

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT This study assessed human health risks associated with exposure to potentially toxic metals (PTMs) in soils and leafy vegetables cultivated in smallholder agricultural systems in Northeastern Brazil. Soil and vegetable samples were collected from 18 agricultural areas and analyzed for cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), nickel

Antibacterial Activity of Fresh and Autoclaved Platelet‐Rich Fibrin on Pseudomonas aeruginosa: An In Vitro Study

open access: yesJournal of Clinical Laboratory Analysis, EarlyView.
This in vitro study compared the antibacterial effects of fresh and autoclaved platelet‐rich fibrin (PRF) on Pseudomonas aeruginosa (P. aeruginosa). Using standardized methodologies, that is, disk diffusion, colony‐forming unit assays, and scanning electron microscopy, this study reported that both fresh and autoclaved PRF exhibit antibacterial effects

Irregularity in Daily Activities Predicts Depression via Reduced Perceived Control: A Daily Diary Study

open access: yesJournal of Clinical Psychology, EarlyView.
ABSTRACT Objectives Disruptions in social rhythm—referring to irregularities in daily activities such as meals, work, and social interactions—have been associated with increased psychological distress, including depression. While circadian rhythm‐related factors (e.g., sleep quality) have been proposed as key mechanisms underlying this link, emerging ...

Diagnostic modulation of subgingival proteomic biomarkers by age and smoking habits in periodontitis

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Although age and smoking influence the periodontal proteome, their impact on subgingival biomarkers for diagnosing periodontitis remains unclear. This multicenter study assessed their influence on subgingival proteins for disease detection.

Mass Spectrometry Structural Proteomics Enabled by Limited Proteolysis and Cross‐Linking

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The exploration of protein structure and function stands at the forefront of life science and represents an ever‐expanding focus in the development of proteomics. As mass spectrometry (MS) offers readout of protein conformational changes at both the protein and peptide levels, MS‐based structural proteomics is making significant strides in the
