Intestinal permeability biomarkers in patients with schizophrenia: Additional support for the impact of lifestyle habits.

Background: Emerging evidence suggests a potential association between "leaky gut syndrome" and low-grade systemic inflammation in individuals with psychiatric disorders, such as schizophrenia. Gut dysbiosis could increase intestinal permeability, allowing the passage of toxins and bacteria into the systemic circulation, subsequently triggering immune-reactive responses. This study delves into understanding the relationship between plasma markers of intestinal permeability and symptom severity in schizophrenia.

Probing the oral-brain connection: oral microbiome patterns in a large community cohort with anxiety, depression, and trauma symptoms, and periodontal outcomes.

The role of the oral microbiome in mental health has recently been appreciated within the proposed oral-brain axis. This study examined the structure and composition of the salivary microbiome in a large-scale population-based cohort of individuals reporting mental health symptoms (n = 306) compared to mentally healthy controls (n = 164) using 16S rRNA sequencing. Mental health symptoms were evaluated using validated questionnaires and included depression, anxiety, and posttraumatic stress disorder (PTSD), with accompanying periodontal outcomes.

A network analysis investigating the associations between posttraumatic stress symptoms, markers of inflammation and metabolic syndrome.

Chronic systemic inflammation has been implicated in trauma exposure, independent of a psychiatric diagnosis, and in posttraumatic stress disorder (PTSD) and its highly comorbid conditions, such as metabolic syndrome (MetS). The present study used network analysis to examine the interacting associations between pro-inflammatory cytokines, posttraumatic stress (PTS) symptoms and symptom clusters, and individual components of MetS, in a cohort of 312 participants (n = 139 PTSD cases, n = 173 trauma-exposed controls). Pro-inflammatory cytokines were measured in serum samples using immunoturbidimetric and multiplex assays.

The gut-microbiota-brain axis in a Spanish population in the aftermath of the COVID-19 pandemic: microbiota composition linked to anxiety, trauma, and depression profiles.

The prevalence of anxiety and depression soared following the COVID-19 pandemic. To effectively treat these conditions, a comprehensive understanding of all etiological factors is needed. This study investigated fecal microbial features associated with mental health outcomes (symptoms of anxiety, depression, or posttraumatic stress disorder (PTSD)) in a Spanish cohort in the aftermath of the COVID-19 pandemic.

Color stability of a resin nanoceramic after surface treatments, adhesive cementation, and thermal aging.

Statement Of Problem: Whether color changes in resin nanoceramic (RNC) restorations can occur because of material and adhesive interface degradation is unclear.

Purpose: The purpose of this in vitro study was to evaluate the color of RNCs submitted to surface treatments, cementation, and aging.

Material And Methods: RNC specimens (N=120) were produced with a thickness of 0.

Decreased oxytocin plasma levels and oxytocin receptor expression in borderline personality disorder.

Introduction: Borderline personality disorder (BPD) is characterized by intense affective reactions with underlying social and interpersonal cognitive deficits. Oxytocin has largely been associated with both stress regulation and social cognition in psychiatric patients and in non-clinical populations in previous studies. Finally, abnormal oxytocin levels have been preliminary reported in BPD patients.

Potent anticholinesterasic and neuroprotective pyranotacrines as inhibitors of beta-amyloid aggregation, oxidative stress and tau-phosphorylation for Alzheimer's disease.

Herein we describe the synthesis and in vitro biological evaluation of thirteen new, racemic, diversely functionalized 2-chloroquinolin-3-yl substituted PyranoTacrines (PTs) as multipotent tacrine analogues for Alzheimer's disease (AD) therapy. Among these compounds, 1-(5-amino-4-(2-chloro-7-methoxyquinolin-3-yl)-2-methyl-6,7,8,9-tetrahydro-4H-pyrano [2,3-b]quinolin-3-yl)éthanone (9) and ethyl 5-amino-4-(2-chloroquinolin-3-yl)-2-methyl-6,7,8,9-tetrahydro-4H-pyrano[2,3-b]quinoline-3-carboxylate (4) were found to be non-neurotoxic agents in human neuroblastoma SHSY5Y cells.
