Curcumin administration mitigates periodontitis-induced tissue damage in hypercholesterolemic rats: a natural preventive approach.

This study investigated the preventive effect of curcumin (CUR) on tooth-supporting structures in hypercholesterolemic (HC) rats with periodontitis (P). Wistar rats (8 weeks old) (n = 30) were assigned to six groups based on dietary intake, CUR-piperine combination treatment and P induction. P was induced in four groups using a ligature model.

Extracellular vesicles in tumor-adipose tissue crosstalk: key drivers and therapeutic targets in cancer cachexia.

Cancer cachexia is a complex metabolic syndrome characterized by unintentional loss of skeletal muscle and body fat. This syndrome is frequently associated with different types of cancer and negatively affects the prognosis and outcome of these patients. It involves a dynamic interplay between tumor cells and adipose tissue, where tumor-derived extracellular vesicles (EVs) play a crucial role in mediating intercellular communication.

Optic neuritis in demyelinating diseases: study of 38 cases.

Background:  Optic neuritis is an inflammation of the optic nerve caused by genetic factors, external influences, and the activation of cross-reactive immune responses to infections.

Objective:  To describe the clinical and epidemiological characteristics of patients presenting optic neuritis as the initial symptom of some demyelinating diseases, divided among multiple sclerosis (MS), neuromyelitis optica spectrum disorder (NMOSD), and myelin oligodendrocyte glycoprotein-immunoglobulin G (MOG-IgG)-associated disorders (MOGADs).

Methods:  Thirty-eight patients who had optic neuritis as their first symptom and later developed MS, NMOSD, or MOGADs were analyzed.

An untargeted metabolomic study using MALDI-mass spectrometry imaging reveals region-specific biomarkers associated with bowel inflammation.

Introduction: Inflammatory bowel diseases (IBDs) are chronic immune driven intestinal disorders with marked metabolic alteration. Mass spectrometry imaging (MSI) enables the direct visualization of biomolecules within tissues and facilitates the study of metabolic changes. Integrating multiple spatial information sources is a promising approach for discovering new biomarkers and understanding biochemical alteration within the context of the disease.

Better cardiometabolic/inflammatory profile is associated with differences in the supraclavicular adipose tissue activity of individuals with T2DM.

Purpose: Brown adipose tissue (BAT), located in the supraclavicular region, has been associated with a better cardiometabolic profile and reduced risk of developing non-communicable chronic diseases (NCD), in addition to being associated with a healthier phenotype in obesity. However, it is unknown whether greater supraclavicular adipose tissue activity could be associated with a healthier metabolic profile in people already diagnosed with type 2 diabetes (T2DM). Thus, the present work evaluated if supraclavicular adipose tissue activity is associated with metabolic and molecular markers in individuals with T2DM.
