The current study was carried out to evaluate the in-vitro and in-vivo efficiency of alphaglucosidase inhibitor of marine actinobacteria in the control of postprandial hyperglycaemia.Soil samples were collected from salterns, coastal area in Kothapatnam, Ongole, AndhraPradesh, India. Among the actinobacterial isolates tested for yeastα-glucosidase inhibitoryactivity, only three isolates showed ...

High fasting plasma concentrations of isoleucine, phenylalanine, and tyrosine have been associated with increased risk of hyperglycaemia and incidence of type 2 diabetes. Whether these associations are diet or metabolism driven is unknown. We examined how the dietary protein source affects the postprandial circulating profile of these three diabetes associated amino acids (DMAAs) and tested whe...

SREBP1c is a key lipogenic transcription factor activated by insulin in the postprandial state. Although SREBP1c appears to be involved in suppression of hepatic gluconeogenesis, the molecular mechanism is not thoroughly understood. Here we show that CRY1 is activated by insulin-induced SREBP1c and decreases hepatic gluconeogenesis through FOXO1 degradation, at least, at specific circadian time...

Background: Diabetes mellitus is a chronic disease. Decreasing postprandial hyperglycemia by retarding glucose absorption through inhibiting carbohydrates digesting enzymes (α-amylase and α-glucosidase) is one of many approaches used for the management of this disease. This study was aimed at evaluating the normoglycaemic potential of Helianthus annuus leaf. Methods: The effect o...

BACKGROUND In patients with both Type 1 and Type 2 diabetes endogenous insulin secretion falls with time which changes treatment requirements, however direct measurement of endogenous insulin secretion is rarely performed. We aimed to assess the impact of endogenous insulin secretion on postprandial glucose increase and the effectiveness of prandial exogenous insulin. METHODS We assessed endo...

Oxidative stress, through the production of reactive oxygen species (ROS), has been proposed as the root cause underlying the development of insulin resistance, beta-cell dysfunction, impaired glucose tolerance and type 2 diabetes mellitus (T2DM). It has also been implicated in the progression of long-term diabetes complications, including microvascular and macrovascular dysfunction. Excess nou...

Insulin therapy remains the cornerstone of effective diabetes management. Timely intensification of insulin therapy reduces the progression of diabetes and the development of diabetes-related complications. Given that overall hyperglycaemia is a relative contribution of both fasting and postprandial hyperglycaemia, use of basal insulin alone may not achieve optimal glucose control due to its in...

Diabetes mellitus is associated with accelerated atherosclerosis and increased morbidity and mortality in micro-and macrovascular complications. The metabolic derangements that accompany diabetes can adversely influence platelets and vascular endothelial function, which may contribute to the pathogenesis of diabetic angiopathy. This thesis aimed to examine the effect of acute and postprandial h...
