diabetes mellitus is one of the most common endocrine diseases and its type ii is the major form of diabetes, accounting for 90% of cases worldwide. the inhibition of carbohydrate hydrolyzing enzymes such as ?-amylase can be an important strategy in the control of blood glucose levels in patients with type ii diabetes. in this investigation, three morus species, m. alba, m. alba var. nigra and ...

Postprandial hyperglycemia is characterized by hyperglycemic spikes that induce endothelial dysfunction, inflammatory reactions and oxidative stress, which may lead to progression of atherosclerosis and occurrence of cardiovascular events. Emerging data indicate that postprandial hyperglycemia or even impaired glucose tolerance may predispose to progression of atherosclerosis and cardiovascular...

Hyperglycemia is a major risk factor for both the microvascular and macrovascular complications in patients with type 2 diabetes. This review summarizes the cardiovascular results of large outcomes trials in diabetes and presents new evidence on the role of hyperglycemia, with particular emphasis on postprandial hyperglycemia, in adverse cardiovascular outcomes in patients with type 2 diabetes....

Chronic hyperglycemia, usually assessed from HbA1c determinations, results in excessive glycation and generation of oxidative stress. As a consequence, chronic hyperglycemia has been identified as a risk factor for diabetes complications leading to accelerated atherosclerosis. Both fasting and postprandial hyperglycemia contribute to this process. However the acute glucose fluctuations that occ...

Increasing evidence suggests that the postprandial state is a contributing factor to the development of atherosclerosis. In diabetes, the postprandial phase is characterized by a rapid and large increase in blood glucose levels, and the possibility that the postprandial "hyperglycemic spikes" may be relevant to the onset of cardiovascular complications has recently received much attention. Epid...

Atherosclerotic vascular disease is more common in diabetic than in nondiabetic individuals. Diabetic macrovascular disease also has a more severe course with greater prevalence of multiple-vessel coronary artery disease and more diffuse elongated atheromas in affected blood vessels. In this review, we discuss possible reasons for increased incidence of cardiovascular (CV) events in individuals...

BACKGROUND In diabetic patients, postprandial hyperglycemia is a more powerful risk factor for cardiovascular disease than fasting hyperglycemia itself. A negative influence of acute hyperglycemia on systemic endothelial function (brachial artery) has been shown. However, myocardial perfusion during postprandial hyperglycemia has not been investigated. METHODS AND RESULTS We evaluated the eff...

The results of the Nateglinide And Valsartan in Impaired Glucose Tolerance Outcomes Research (NAVIGATOR) trial have been recently reported (1–2). Nateglinide, a member of the meglitinide class, which has been shown to lower postprandial hyperglycemia by increasing the first phase of insulin secretion, was not effective in decreasing both the new cases of diabetes and the new cardiovascular even...

Repeated mental stress may lead to chronic alterations in cortisol and catecholamine concentrations and to insulin resistance. Furthermore, chronically elevated cortisol concentrations may favour the development of abdominal obesity and of the metabolic syndrome. Oxidative stress impairs glucose uptake in muscle and fat and correlates with BMI. Obese subjects with type 2 diabetes, especially so...

BACKGROUND α-glucosidase inhibitors regulate postprandial hyperglycemia (PPHG) by impeding the rate of carbohydrate digestion in the small intestine and thereby hampering the diet associated acute glucose excursion. PPHG is a major risk factor for diabetic vascular complications leading to disabilities and mortality in diabetics. Cinnamomum zeylanicum, a spice, has been used in traditional medi...
