Oxidative stress and protein modifications are frequently observed in numerous disease states. Glucose constitutes a vital nutrient necessary to cellular oxygen metabolism. However, hyperglycemia-associated damage is an important factor in diabetes disorders. Albumin, the major circulating protein in blood, can undergo increased glycation in diabetes. From recent studies, it has become evident ...

Beta vulgaris is an edible plant and herbal medicine traditionally used to treat diabetes breast cancer protect against liver damage induced by HF diet. The aim of this investigation evaluate the inhibitory activity B. (CH) extract on formation advanced glycation end products (AGEs) fluorescent Non-fluorescent AGEs, protein oxidation, aggregation in vitro model glucose fructose Congo red test. ...

Despite the high levels of polyphenolic phytochemicals in grain sorghum and its position as a major food staple, there has been a lack of research on its effects on both animal and human health and disease prevention. These phenolic compounds, mainly located in the bran fraction, result in the plant having substantial antioxidant properties. This study examined the effect of ethanol extracts of...

Non-enzymatic glycation is implicated in the development of various diseases such as Alzheimer's and diabetes mellitus. However, it is also observed during the physiologic process of aging. There is considerable interest in the contribution of oxidative stress to diabetes mellitus. An increase in the generation of reactive oxygen species can occur by non-enzymatic glycation and glucose autoxida...

NMR is ideal for characterizing non-enzymatic protein glycation, including AGEs (advanced glycation endproducts) underlying tissue pathologies in diabetes and ageing. Ribose, R5P (ribose-5-phosphate) and ADPR (ADP-ribose), could be significant and underinvestigated biological glycating agents especially in chronic inflammation. Using [U-13C]ribose we have identified a novel glycoxidation adduct...

Glycation is associated with several neurodegenerative disorders, including Alzheimer's disease (AD), where it potentiates the aggregation and toxicity of proteins such as β-amyloid (Aβ). Published studies support the anti-glycation and neuroprotective effects of several polyphenol-rich fruits, including berries, which are rich in anthocyanins. Herein, blackberry, black raspberry, blueberry, cr...

BACKGROUND Diabetes mellitus is a metabolic disorder of epidemic proportion, projected to become the major cause of morbidity and mortality in the world in future. Despite extensive research in understanding this disease at molecular level, and the discovery of new drugs, diabetes and its complications remain largely untreated. Many of the late diabetic complications are associated with the gly...

The non-enzymatic glycosylation (glycation) of proteins is a common post-translational modification found in diabetes under conditions of hyperglycaemia [l]. The rates and extent of glycation are dependent on both the ambient glucose concentration and the half life of the particular protein [2]. We have investigated the process of glycation with human insulin in vitro quantitating the extent of...

Glycation and its products cause a host of pathological conditions but their exact roles are yet to be determined. Pyrraline, a key product of glycation, and a novel pyrraline-derived cross-link have been incorporated into collagenous peptides via Maillard condensations performed on resin-bound peptide sequences.

BACKGROUND Advanced glycation end products (AGEs) have been linked to pathogenic mechanisms of diabetes mellitus. However, little is known about the contribution of protein glycation to periodontal disease in patients with diabetes. Therefore, this study investigated whether glycation of type I collagen (COLI) and fibronectin (FN) modified the behavior of human gingival fibroblasts (hGFs) and p...
