DNA damage and cell death in human oral squamous cell carcinoma cells: The potential biological effects of cannabidiol.

Objective: The present study examined the in vitro effects on oral squamous cell carcinoma cells (HSC-3) of cannabidiol (CBD), the main chemical component of Cannabis, proposed as a novel adjuvant therapy in the treatment of cancers.

Design: Cell viability (MTT assay), morphology (SEM), apoptosis and cell cycle (flow cytometry), and DNA damage (phospho-γ-H2AX immunofluorescence) were evaluated. Cytotoxicity was evaluated with concentrations between 100 µM and 1 µM, and two concentrations were selected for subsequent analysis: 25 µM, as toxic dose, and 6.

Relaxometric properties and biocompatibility of a novel nanostructured fluorinated gadolinium metal-organic framework.

A novel Gd-MOF based on tetrafluoro-terephthalic acid has been synthesized and its structure has been solved using X-ray single crystal diffraction data. The compound, with the formula [Gd(FBDC)·HO]·DMF, is isostructural with other Ln-MOFs based on the same ligand and has been recently reported. Its crystals were also reduced to nanometer size by employing acetic acid or cetyltrimethylammonium bromide (CTAB) as a modulator.

Acute and chronic cannabidiol treatment: In vitro toxicological aspects on human oral cells.

Cannabidiol is gaining increasing interest for its potential anti-inflammatory, immunomodulatory, and antineoplastic effects. The purpose of this study is to investigate the biological effects of acute and chronic CBD administration on gingival fibroblasts and oral keratinocytes. Viability, morphology, migration, apoptosis and cell cycle, and expression of related genes (p53, BCL2, p21, and BAX) and of endocannabinoid system receptors (CB1, CB2 and GPR55) with real-time PCR and DNA damage with phospho-γ-H2AX immunofluorescence detection were analyzed.

Role of histamine H receptor in the anti-inflammatory pathway of glucocorticoid-induced leucin zipper (GILZ) in a model of lung fibrosis.

Introduction: This study investigates the interactions between histaminergic system and glucocorticoid-induced leucin zipper (GILZ) in the inflammatory process and glucocorticoid modulation in lung fibrosis.

Methods: Wild-type (WT) and GILZ Knock-Out (KO) mice were treated with bleomycin (0.05 IU) or saline, delivered by intra-tracheal injection.

Anti-Inflammatory Effects of Synthetic Peptides Based on Glucocorticoid-Induced Leucine Zipper (GILZ) Protein for the Treatment of Inflammatory Bowel Diseases (IBDs).

Glucocorticoids (GCs) are commonly used to treat autoimmune and inflammatory diseases, but their clinical effects and long-term use can lead to serious side effects. New drugs that can replace GCs are needed. Glucocorticoid-induced leucine zipper (GILZ) is induced by GCs and mediates many of their anti-inflammatory effects, such as inhibiting the pro-inflammatory molecule NF-κB.

miRNAs and Alzheimer's Disease: Exploring the Role of Inflammation and Vitamin E in an Old-Age Population.

Alzheimer's disease (AD) is the most frequent cause of dementia worldwide and represents one of the leading factors for severe disability in older persons. Although its etiology is not fully known yet, AD may develop due to multiple factors, including inflammation and oxidative stress, conditions where microRNAs (miRNAs) seem to play a pivotal role as a molecular switch. All these aspects may be modulated by nutritional factors.

Glucocorticoid Therapy in Inflammatory Bowel Disease: Mechanisms and Clinical Practice.

Inflammatory bowel disease (IBD) comprises ulcerative colitis (UC) and Crohn's disease (CD). IBD etiopathology is multifactorial and involves alteration of immune cells and chronic activation of the inflammatory cascade against yet unknown environmental factors that trigger the disease. IBD therapy aims at improving the quality of life and reducing the risk of disease-related complications to avoid the need for surgery.

Examining Cervical Cancer Preventive Behaviors for Latinx Transmasculine Individuals among Medical Students.

Latinx transmasculine men (LTM) can be at a particularly high risk for cervical cancer as they lie at the intersection of two health disparity populations (gender and ethnic minorities). Previous research using self-report measures has documented how negative interactions with providers are a key barrier for cervical cancer screening among LTM. However, no research to date has examined, via direct observation, cervical cancer preventive behaviors in clinical interactions with LTM.
