glyoxal/inflammation

To explore mechanisms of diabetes-associated vascular endothelial cells (ECs) injury, human umbilical vein ECs were treated for 24h with high glucose (HG; 26mM), advanced glycation end-products (AGEs; 100mug/ml) or their intermediate, glyoxal (GO: 50-5000muM). HG and AGEs had no effects on ECs

Methylglyoxal (MG) and glyoxal (GO) are suggested to be associated with the development of neurodegenerative pathologies. However, their peripheral levels in relation to cognitive decline and their effects on key factors in neuronal cells are poorly investigated. The aim of this study was to

Background: Glyoxal (GO), and methylglyoxal (MGO) are among the most toxic compounds emitted by electronic cigarette (E-cig) and regular tobacco cigarette smoke. Airway diseases presented mucus over production as their major

Diacetyl, methylglyoxal, and glyoxal are α-dicarbonyl catabolites prone to nucleophilic additions of amino groups of proteins and nucleobases, thereby triggering adverse biological responses. Because of their electrophilicity, in aqueous medium, they exist in a phosphate-catalyzed dynamic

The relevance of reactive oxygen species (ROS) in the pathogenesis of inflammatory diseases is widely documented. Immunochemical detection of ROS DNA adducts has been developed, however, recognition of glyoxal-DNA adducts has not previously been described. We have generated a polyclonal antibody

Insulin resistance and hepatotoxicity induced in high fructose fed rats may involve fructose derived endogenous toxins formed by inflammation. Thus fructose was seventy-fold more toxic if hepatocytes were exposed to non-toxic levels of hydrogen peroxide (H(2)O(2)) released by inflammatory cells.

Glyoxal (GO) and methylglyoxal (MGO) cause protein and nucleic acid carbonylation and oxidative stress by forming reactive oxygen and carbonyl species which have been associated with toxic effects that may contribute to cardiovascular disease, complications associated with diabetes mellitus,

Under inflammatory conditions, both 8-nitroguanine (NO2Gua) and 8-hydroxydeoxyguanosine (8-OHdG) are found in tissues. Measurements of the two types of damaged bases on nucleotides are expected to provide information pointing to the possible correlation between inflammation and carcinogenesis. For

BACKGROUND Atopic dermatitis (AD) is a highly pruritic, chronic inflammatory skin disease associated with hyperreactivity to environmental triggers. Among those, outdoor air pollutants such as particulate matter (PM) have been reported to aggravate pre-existing AD. However, underlying mechanisms of

BACKGROUND Beta-defensins (hBDs) provide antimicrobial and chemotactic defense against bacterial, viral and fungal infections. Human β-defensin-2 (hBD-2) acts against gram-negative bacteria and chemoattracts immature dendritic cells, thus regulating innate and adaptive immunity. Immunosuppression

The plasma of diabetic or uremic patients and of those receiving peritoneal dialysis treatment have increased levels of the glucose-derived dicarbonyl metabolites like methylglyoxal (MGO), glyoxal (GO), and 3-deoxyglucosone (3-DG). The elevated dicarbonyl levels can contribute to the development of

OBJECTIVE In view of the potential pharmacophoric nature of imidazole nucleus, two series of imidazole derivatives, 2,4-disubstituted-1 H-imidazoles (2a-m) and 1,2,4-trisubstituted-1 H-imidazoles (3a-m), were synthesized with an aim of obtaining dual acting compounds i.e., anti-inflammatory and

Diabetic retinopathy (DR) is a chronic, low-grade inflammatory disease. We aimed to investigate the regulatory effects of erythropoietin (EPO) on the inflammatory cytokine production by Muller cells under the condition of DR. The expression levels of TNF-alpha, IL-1beta, IL-6 and VEGF in cultured

The accumulation of advanced glycation end products (AGEs) in brains with Alzheimer's disease (AD) has been implicated in the formation of insoluble deposits such as amyloid plaques and neurofibrillary tangles. AGEs are also known to activate glia, resulting in inflammation and neuronal dysfunction.

A thermolyzed diet has the potential of providing exogenous oxidative stress in the form of advanced glycation end-products (AGE) and decreased thiamin. There is then a possibility that it could result in intracellular exposure to alpha-oxoaldehydes (glyoxal and methylglyoxal (MG)) with metabolic
