Glycolipid metabolic disorders (GLMDs) are various resulting from dysregulation in glycolipid levels, consequently leading to an increased risk of obesity, diabetes, liver dysfunction, neuromuscular complications, and cardiorenal vascular diseases (CRVDs). In patients with GLMDs, excess caloric intake a lack physical activity may contribute oxidative stress (OxS) systemic inflammation. This study aimed review the connection between GLMD, OxS, metainflammation, onset CRVD.

Perivascular spaces (PVS) and their enlargement (EPVS) have been gaining interest as EPVS can be visualized non-invasively by magnetic resonance imaging (MRI) when viewing T-2-weighted images. are most commonly observed in the regions of basal ganglia centrum semiovale; however, they also identified frontal cortex hippocampal regions. known to increased aging hypertension, considered a biomarker cerebral small vessel disease (SVD). Interest has significantly because these PVS now an essential conduit necessary for glymphatic pathway provide efflux metabolic waste.

Abstract Metabolic syndrome (MetS) is considered a metabolic disorder that has been steadily increasing globally and seems to parallel the prevalence of obesity. It consists cluster risk factors, which traditionally includes obesity hyperlipidemia, hyperinsulinemia, hypertension, hyperglycemia. These four core factors are associated with insulin resistance (IR) importantly, MetS known increase for developing cerebrocardiovascular disease type 2 diabetes mellitus. The had its early origins in IR X. undergone numerous name changes additional variables being added over years; however, it still remains worldwide past three decades.

Brain Injury: Response to Injury Wound-Healing Mechanisms and Enlarged Perivascular Spaces in Obesity, Metabolic Syndrome, and Type 2 Diabetes Mellitus

Medicina, Год журнала: 2023, Номер 59(7), С. 1337 - 1337

Embryonic genetic mechanisms are present in the brain and ready to be placed into action upon cellular injury, termed response injury wound-healing (RTIWH) mechanism. When injured, regional endothelial cells initially undergo activation dysfunction with initiation of hemostasis, inflammation (peripheral leukocytes, innate microglia, perivascular macrophage cells), proliferation (astrogliosis), remodeling, repair, resolution phases if injurious stimuli removed. In conditions wherein chronic, as occurs obesity, metabolic syndrome, type 2 diabetes mellitus, this process does not there is persistent RTIWH remodeling. Indeed, unique, that it utilizes its neuroglia: microglia cell, along peripheral inflammatory astroglia, instead scar-forming fibrocytes/fibroblasts.

In recent years, the incidence of metabolic syndrome (MS) has increased due to lifestyle-related factors in developed countries. MS represents a group conditions that increase risk diabetes, cardiovascular diseases, and other severe health problems. Low-grade chronic inflammation is now considered one key aspects could be defined as new factor. Indeed, an visceral adipose tissue, typical obesity, contributes development inflammatory state, which, turn, induces production several proinflammatory cytokines responsible for insulin resistance. Psoriasis relapsing skin disease characterized by release pro-inflammatory cytokines, which can contribute different pathological within spectrum MS.

Sugarcane, a globally cultivated crop constituting nearly 80% of total sugar production, yields residues from harvesting and production known for their renewable bioactive compounds with health-promoting properties. Despite previous studies, the intricate interplay extracts diverse sugarcane byproducts biological attributes remains underexplored. This study focused on extracting lipid fraction blend selected (straw, bagasse, filter cake) using ethanol. The resulting extract underwent comprehensive characterization, including physicochemical analysis (FT-IR, DSC, particle size distribution, color) chemical composition assessment (GC-MS). properties were evaluated through antihypertensive (ACE), anticholesterolemic (HMG-CoA reductase), antidiabetic (alpha-glucosidase Dipeptidyl Peptidase-IV) assays, alongside in vitro biocompatibility assessments Caco-2 Hep G2 cells. phytochemicals identified, such as β-sitosterol 1-octacosanol, likely contribute to extract's antidiabetic, anticholesterolemic, potential, given association various beneficial bioactivities. exhibited substantial effects, inhibiting α-glucosidase (5-60%) DPP-IV activity (25-100%), potential HMG-CoA reductase inhibition (11.4-63.2%), ACE (24.0-27.3%). These findings lay groundwork incorporating these ingredients into development food supplements or nutraceuticals, offering preventing managing metabolic syndrome-associated conditions.

Journal of Clinical Medicine, Год журнала: 2025, Номер 14(8), С. 2611 - 2611

Опубликована: Апрель 10, 2025

Chronic obstructive pulmonary disease (COPD) is a progressive and debilitating condition characterized by airflow limitations systemic inflammation. The interaction between the metabolic inflammatory pathways plays key role in progression, with leptin insulin emerging as pivotal regulators. Leptin, an adipokine that regulates energy homeostasis, insulin, primary regulator of glucose metabolism, are both altered COPD patients. This narrative review provides in-depth examination roles pathogenesis, focusing on molecular mechanisms through which these regulators interact how their dysregulation contributes to spectrum extrapulmonary manifestations. These disturbances not only exacerbate symptoms but also increase risk comorbidities such syndrome, diabetes, cardiovascular disease, or muscle wasting. By exploring underlying COPD, this underscores significance metabolic-inflammatory axis, suggesting restoring balance modulation could offer novel therapeutic strategies for improving clinical outcomes.

Metabolic syndrome (MetS) is a major global public health concern due to its rising prevalence and association with increased risks of cardiovascular disease type 2 diabetes. Emerging evidence suggests that environmental chemical exposures may play significant role in the development MetS by disrupting metabolic pathways. This study used data from 2,960 participants Korean National Environmental Health Survey (KoNEHS) cycle 4 (2018-2020) examine associations between risk through machine learning (ML) approaches. Eight ML algorithms were applied, multilayer perceptron (MLP) random forest (RF) models identified as optimal predictors. The MLP achieved an AUC 0.79, RF highest F1 score 0.82. Both highlighted PFOA PFOS, alongside age BMI, key SHapley Additive exPlanations (SHAP) partial dependence plots (PDP) revealed both linear nonlinear exposure-response patterns, suggesting threshold effects for chemicals. These findings underscore importance incorporating into assessments. provided robust predictive performance novel insights interactions, advocating regulatory measures reduce harmful integrate factors prevention strategies.
