TAM pathway proteins as novel salivary biomarkers for periodontitis

open access: yesJournal of Periodontology, EarlyView.
Abstract Background The identification of molecular biomarkers that help clinicians in early diagnosis is a key focus of periodontal research. The major aim of this cross‐sectional observational study was to assess whether salivary TAM pathway protein levels have the potential to discriminate between periodontally healthy or gingivitis controls and ...

Effects of testosterone and high‐dose anabolic steroids on orthodontic‐induced bone remodeling and root resorption: An animal study

open access: yesJournal of Periodontology, EarlyView.
Abstract Background This study investigates the impact of disruptions in testosterone levels on bone remodeling, root resorption, and periodontal ligament (PDL) during orthodontic tooth movement (OTM) in a pubertal male rat model. Methods Testosterone deficiency was induced through orchiectomy, and the anabolic‐androgenic steroid (AAS, testosterone ...

Significant kidney impairment in pediatric inflammatory bowel disease and practice points for pediatric gastroenterologists

open access: yesJournal of Pediatric Gastroenterology and Nutrition, EarlyView.
Abstract Objectives Children with inflammatory bowel disease (IBD) have an increased risk of developing kidney disorders, which may cause significant kidney function impairment (SKI) or lead to chronic kidney disease (CKD). In this study we aimed to provide insights in causes and diagnoses of SKI cases and to provide recommendations for pediatric ...

From shape to source: sedimentary charcoal morphology as a proxy for tropical burned biomass composition

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Sedimentary charcoal elongation is increasingly being used in paleoecology to distinguish herbaceous from woody fuel in past fires. However, the relationship between charcoal morphotypes and plant types has never been formally tested in tropical environments, despite its potential to improve understanding of fire regimes and deforestation, and

Reusable SERS Substrate Based on AuNP/PS‐b‐P2VP Nanocomposites With Photocatalytic Activity

open access: yesJournal of Raman Spectroscopy, EarlyView.
We developed a bifunctional SERS substrate by assembling AuNPs on PS‐b‐P2VP thin films, capable of both sensitive molecular detection and UV‐assisted self‐cleaning. The platform demonstrates excellent reusability over four adsorption–degradation cycles, driven by a hot‐hole‐mediated photocatalytic mechanism without semiconductors.

Early life abuse and neglect in breast cancer survivors: Associations with physical and psychological health throughout diagnosis and survivorship

open access: yesJournal of Traumatic Stress, EarlyView.
Abstract Childhood abuse and neglect worsen physical and mental health through adulthood. This study examined how childhood adversity affected physical and psychological symptoms associated with breast cancer treatment and survivorship at three points within the cancer trajectory. Breast cancer survivors (N = 209) were recruited following diagnosis and
