Current trends in management of hyperglycaemia in surgical patients with diabetes mellitus: a review
A large amount of clinical evidences demonstrates a clear association between long-term and/or stress-related hyperglycaemia, and development complications after surgery. The incidences perioperative hyperglycaemia are demonstrated in 20–80 % all cases depending on the type elective surgery, with highest rate registered cardiac most studied pathophysiological Diabetes Mellitus (DM) patients are...
Diabetes Mellitus is a serious global health problem. Both type 1 and type 2 diabetes markedly increase the risk of microvascular and macrovascular complications. Chronic complications of diabetes (retinopathy, nephropathy, neuropathy, and diabetes accelerated arteriosclerosis) represent a major medical and economical concern. Several pathogenic mechanisms were proposed to be responsible for th...
Thiamine acts as a coenzyme for transketolase (Tk) and for the pyruvate dehydrogenase and α-ketoglutarate dehydrogenase complexes, enzymes which play a fundamental role for intracellular glucose metabolism. The relationship between thiamine and diabetes mellitus (DM) has been reported in the literature. Thiamine levels and thiamine-dependent enzyme activities have been reduced in DM. Genetic st...
Glucose and glutamine serve as the two primary carbon sources in proliferating cells, and uptake of both nutrients is directed by growth factor signaling. Although either glucose or glutamine can potentially support mitochondrial tricarboxylic acid (TCA) cycle integrity and ATP production, we found that glucose deprivation led to a marked reduction in glutamine uptake and progressive cellular a...
Protein-O-linked N-Acetyl-β-D-glucosaminidase (O-GlcNAcase, OGA; also known as hexosaminidase C) participates in a nutrient-sensing, hexosamine signaling pathway by removing O-linked N-acetylglucosamine (O-GlcNAc) from key target proteins. Perturbations in O-GlcNAc signaling have been linked to Alzheimer's disease, diabetes and cancer. Mammalian O-GlcNAcase exists as two major spliced isoforms ...
Diabetic neuropathy (DN) is a widespread disabling disorder comprising peripheral nerves' damage. DN develops on a background of hyperglycemia and an entangled metabolic imbalance, mainly oxidative stress. The majority of related pathways like polyol, advanced glycation end products, poly-ADP-ribose polymerase, hexosamine, and protein kinase c all originated from initial oxidative stress. To da...
Intact chloroplasts of spinach (Spinacia oleracea L.), sunflower (Helianthus annuus L.), and maize (Zea mays L.) mesophyll cells contained 0.33, 0.50, and 0.14% of bound hexosamine on a protein basis, respectively. Undifferentiated maize chloroplasts contained 0.19%. Values for chloroplast lamellae were, respectively, 0.16, 0.18, 0.12, and 0.06% and for envelope membranes they were 1.6, 2.5, 3....
The concentration of hexosamine, a marker for mucin, was determined and related to the degree of cholesterol saturation and to the occurrence of cholesterol crystals in gall bladder bile of gall stone patients (n = 40) and gall stone free subjects (n = 25). Ten of the gall stone patients had been treated with chenodeoxycholic acid (CDCA) and eight with ursodeoxycholic acid (UDCA) three to four ...
