Abstract
We investigated whether heparin interferes with HMGB1/RAGE interaction and prevents the cytokine activity. We used fluorescence spectrometry, circular dichroism spectrometry and SPR biosensor technique to evaluate the effect. After treatment of HMGB1 with different concentrations of heparin (0, 50,...

Abstract
The sRAGE [soluble RAGE (receptor for advanced glycation end-products)] lack the transmembrane and cytoplasmic domain of the full-length receptor and can function as a decoy for RAGE ligands. Recent evidence suggests that sRAGE may be a potential biomarker of RAGE-mediated pathology. The present stu...

Abstract
We investigated whether the biological functions of human basophils can be influenced by AGEs.
We analyzed the effects of AGEs on various functions and markers of human basophils, including CD11b expression, apoptosis, degranulation, and cytokine production.

Abstract
Oxidative stress and resultant accumulation of advanced glycation end products (AGEs) are closely related to the development of cardiovascular disease, which is the major cause of death among end-stage renal disease patients. Several markers of oxidative stress, such as malondialdehyde, oxidized low...

Abstract
Persistently elevated oxidative stress and inflammation precede or occur during the development of type 1 or type 2 diabetes mellitus and precipitate devastating complications. Given the rapidly increasing incidence of diabetes mellitus and obesity in the space of a few decades, new...

Abstract
We investigated the possible mechanisms underlying AGE-related suppression of insulin synthesis. In the rat pancreatic β-cell line INS-1, we found that AGEs induced dephosphorylation of Foxo1 and increased its accumulation in the nucleus. The translocation of Foxo1 subsequently inhibited pancreatic...

Abstract
Skin autofluorescence (SAF) is a new method to noninvasively assess accumulation of advanced glycation endproducts (AGEs) in a tissue with low turnover. Recent progress in the clinical application of SAF as a risk marker for diabetic nephropathy as well as cardiovascular disease in nondiabetic end-s...

Abstract
We evaluated the efficacy of the PPAR-γ agonist rosiglitazone (RSG) in ameliorating peritoneal membrane damage in a mouse PD model, and we analyzed the mechanisms underlying the protection offered by RSG. Exposure of the peritoneum to PD fluid resulted in AGEs accumulation, an inflammatory response...

Abstract
The effects of anaerobic (lens) vs aerobic (skin) environment on carbonyl and oxidant stress are compared using de novo and existing data on advanced glycation and oxidation products in human crystallins and collagen. Almost all modifications increase with age. Methylglyoxal hydroimidazolones, carbo...

Abstract
We successfully isolated approximately 24 mg/L 3-O-rhamnosyl quercetin and 12.9 mg/L 3-O-rhamnosyl kaempferol upon feeding of 0.2 mM of the respective flavonoids and were also able to isolate 3-O-allosyl quercetin. Thus, this study reveals a method that might be useful for the biosynthesis of rhamno...

Abstract
We demonstrate that most of the anti-inflammatory pharmacology of heparin is unrelated to anticoagulant activity. ODSH has low affinity for anti-thrombin III, low anti-Xa, and anti-IIa anticoagulant activities and does not activate Hageman factor (factor XII). Unlike heparin, ODSH does not interact...

While many studies have shown that NAD(+) is important when lifespan is modulated by dietary means, it is uncertain whether or how NAD(+) affects either formation or elimination of altered prote...

Abstract
Nucleobases and DNA react non-enzymatically with sugars, and generate DNA-advanced glycation end products (DNA-AGEs). Incubation of plasmid pBr322 with ribose for 3-7 days caused the transformation of the supercoiled plasmid to the open circular and linear forms. Removal of sugar after an initial 24...

Nevertheless, the present article attempts to offer an overview of known associations between AGEs and vascular complications, in order to draw attention to a less known subje...

Abstract
We investigated the protective role of resveratrol against the AGE-induced impairment on macrophage lipid homeostasis. In THP-1-derived macrophages, RAGE was dose-dependently induced by AGE and played a key role in the AGE-induced cholesterol accumulation. Resveratrol markedly reduced RAGE expressio...

Puerarin acts by inducing the expression of heme oxygenase-1 (HO-1) in a dose- and time-dependent manner. Puerarin was able to enhance phosphorylation of protein kinas...

Abstract
We investigated the effects of kynurenines on AGE synthesis in HLP. We found that incubation with 5 mM ribose or 5 mM ascorbate produced significant quantities of pentosidine, and this was further enhanced in the presence of two different kynurenines (200-500 microM): N-formylkynurenine (Nfk) and ky...

On age-adjusted analyses, diabetes duration, retinopathy, nephropathy and neuropathy were significantly associated with skin AF levels (all P<0.001). AF levels increased significantly with severity in both retinopathy and nephropathy (P<0.001). After adjusting for age, diabetes duration, HbA(1c), sm...

Today this chemical definition has been slightly modified and encompasses an elevation of oxidative metabolites or a relative deficiency of anti-oxidants. Molecular oxygen is...
