The effect of Ca and calmodulin has been studied on adenylate cyclase activity in homogenates of rat islets of Langerhans. EGTA had a stimulatory effect on the enzyme in accord with the known inhibitory effect of Ca. In contrast, the addition of Ca together with calmodulin is stimulatory and demonstrates the existence of a Ca-dependent adenylate cyclase in islets of Langerhans. It is suggested ...

Objective(s): The link between a hyperglycemic intrauterine environment and the development of diabetes later in life has been observed in offspring exposed to gestational diabetes mellitus (GDM), but the underlying mechanisms for this phenomenon are still not clear. Reduced β-cells mass is a determinant in the development of diabetes (type 1 and type 2 diabetes). Some recent studies have provi...

INTRODUCTION: WHO predicts an increase in the number of people with diabetes Indonesia from 8.4 million 2000 to around 21.3 2030. Another marker for measuring insulin resistance is homeostasis model assessment-insulin (HOMA-IR). Bariatric surgery most effective therapy patients both terms weight loss and improvement obesity-related diseases such as Type-2 Diabetes Mellitus (DM). OBJECTIVE: This...

Background and Objective: Capparis spinosa L. belongs to the Capparaceae family for which biological roles such as antioxidant, anti-inflammatory, and antidiabetic effects have been reported. Some active chemical groups including flavonoids, phenols, alkaloids, tannins, and minerals have been detected in these plants [Sci Rew1] . This study aimed to extract the C. spinosa alcoholic extract from...

Beta-cells inside the pancreatic islets of Langerhans are the only source of the hormone insulin. Visualization of pancreatic islets with MRI in the mouse has many potential applications in preclinical diabetes research, because the amount of beta-cells decreases with the onset of the disease. Islets of Langerhans were imaged with a beta-cell specific MRI contrast agent in the excised murine pa...

OBJECTIVE Ganoderma Lucidum (G. Lucidum) has been suggested to increase serum insulin level. This study was undertaken to investigate its direct effect on the islets of Langerhans. MATERIAL AND METHODS Male albino Wistar rats were anesthetized and the islets were isolated after digestion of the pancreas with collagenase. The islets were incubated for 60 min in Krebs bicarbonate buffer contain...

Context: Statins are administered to decrease atherosclerosis in patients with coronary heart disease. These drugs enhance the risk of diabetes by affecting islets insulin secretion. Objectives: Therefore, this systematic review investigates effect statins on secretion Langerhans related original studies. Methods: A preliminary search was performed PubMed, Scopus, Web Science, and ProQuest data...

BACKGROUND DPP-4 inhibitors reportedly exert effects on both alpha and beta cells, and promote the proliferation and survival of beta cells. We investigated the effects of anagliptin on structurally-impaired islets of Langerhans in streptozotocin (STZ)-treated mice, fed either a normal or a high-fat diet. Pdx-1 expression in the pancreas and serum insulin/glucagon concentrations were also exami...

Background Islets of Langerhans transplantation is a promising alternative for glycemic control in patients with type 1 diabetes. The graft site is a factor that has large impact on the functioning of this transplant, and the stomach appears to be a promising location. Our objective is to describe a new experimental model for the grafting of Islets of Langerhans in rat stomachs. Methodology I...

It has been recently proposed that exposure to polychlorinated biphenyls (PCBs) is a risk factor to type 2 diabetes mellitus (DM2). We investigated this hypothesis using long-term in vivo PCB126 exposure to rats addressing metabolic, cellular and proteomic parameters. Male Wistar rats were exposed to PCB126 (0.1, 1 or 10 μg/kg of body weight/day; for 15 days) or vehicle by intranasal instillati...
