BACKGROUND AND OBJECTIVE: Teucrium polium Lamiaceae. an antidiabetic traditional medicine was observed to stimulate insulin secretion and β-cell mass restoration in pancreatic of diabetic rats. Bioactive compounds in T. polium such as terpenoids and flavonoids have a wide range of antioxidant properties. Given this background, our research was aimed at probing the effective molecular mechanism of T. polium which in turn protects the pancreatic β-cells of diabetic rats through attenuation of streptozotocin-induced oxidative stress...

Chronic pancreatitis is a chronic inflammatory disease of the pancreas characterised by irreversible morphological change and typically causing pain and/or permanent loss of function. This progressive, irreversible disease results in destruction of healthy pancreatic tissue and the development of fibrous scar tissue. Gradual loss of exocrine and endocrine function follows, along with clinical manifestations such as steatorrhoea, abdominal pain and diabetes. Nutrition in chronic pancreatitis has been described as a problem area and, until recently, there was little research on the topic...

Transplantation of pancreatic islets or stem cell derived insulin secreting cells is an attractive treatment strategy for diabetes. However, islet transplantation is associated with several challenges including function-loss associated with dispersion and limited vascularization as well as the need for continuous immunosuppression. To overcome these limitations, here we present a novel 3D printed and functionalized encapsulation system for subcutaneous engraftment of islets or islet like cells. The devices were 3D printed with polylactic acid and the surfaces treated and patterned to increase the hydrophilicity, cell attachment and proliferation...

PURPOSE: Indications for total pancreatectomy (TP) have increased, including for diffuse main duct intrapapillary mucinous neoplasms of the pancreas and malignancy; therefore, the need persists for surgeons to develop appropriate endocrine post-operative management strategies. The brittle diabetes after TP differs from type 1/2 diabetes in that patients have absolute deficiency of insulin and functional glucagon. This makes glucose management challenging, complicates recovery, and predisposes to hospital readmissions...

Granzyme A is a protease implicated in the degradation of intracellular DNA. Nucleotide complexes are known triggers of systemic autoimmunity, but a role in organ-specific autoimmune disease has not been demonstrated. To investigate whether such a mechanism could be an endogenous trigger for autoimmunity, we examined the impact of granzyme A deficiency in the NOD mouse model of autoimmune diabetes. Granzyme A deficiency resulted in an increased incidence in diabetes associated with accumulation of single stranded DNA in immune cells and induction of an interferon response in pancreatic islets...

Pancreatitis is an inflammation of the pancreas that can progress from an acute presentation to an acute recurring presentation and eventually to chronic pancreatitis, which is characterized by irreversible morphological changes and scarring of the pancreas. The entity known as hereditary pancreatitis has been recognized in the literature for years and certainly the discovery of the PRSS1 gene in 1996 marked the beginning of a new era of genetic discoveries associated with the disease. Since then, multiple genes have been described as the causing agents of pancreatitis or disease modifiers, some of the most important ones being the PRSS1, SPINK1, CFTR, CASR, CTRC, CLDN2, and CPA1...

Chronic pancreatitis is a progressive fibro-inflammatory disease of the pancreas characterized by irreversible fibrosis of the gland with eventual failure of exocrine and endocrine functions and hallmark features of abdominal pain, malabsorption, malnutrition, diabetes mellitus and pancreatic calcifications. In many patients this disease results from a complex mix of environmental (eg, alcohol, cigarettes, and occupational chemicals), genetic factors and a few patients with hereditary or autoimmune disease...

Prolonged elevated levels of free fatty acids (FFAs) contribute to the impairment of insulin secretion function of pancreatic β cells, a hallmark of type 2 diabetes, which is partly attributed to the dysfunction of G-protein-coupled receptor 40 (GPR40) signaling. Pollen Typhae total flavone (PTF), an extract from a Chinese herbal medicine named Pollen Typhae, has been reported to effectively treat type 2 diabetes, but the underlying mechanisms remain to be fully elucidated. In the present study, palmitic acid (PA), a saturated fatty acid, severely impaired glucose-stimulated insulin secretion (GSIS) in a time-dependent manner in INS-1 cells, and PTF treatment prevented the impairment in a dose-dependent manner...

Objective The rs10229583 polymorphism near paired box gene 4 ( PAX4) is associated with insulin resistance and type 2 diabetes. Mutations in the PAX4 gene may be associated with impaired differentiation/development of pancreatic islet beta cells during fetal development and, consequently, a compromised insulin response to high blood glucose. To ascertain whether this polymorphism plays a role in gestational diabetes mellitus (GDM), we investigated the genotypic and allele frequency differences between GDM and normal pregnancies...

Glucose homeostasis is finely regulated by a number of hormones and peptides released mainly from the brain, gastrointestinal tract, and muscle, regulating pancreatic secretion through cellular receptors and their signal transduction cascades. The endocrine function of the pancreas is controlled by islets within the exocrine pancreatic tissue that release hormones like insulin, glucagon, somatostatin, pancreatic polypeptide, and ghrelin. Moreover, both exocrine and endocrine pancreatic functions are regulated by a variety of hormonal and neural mechanisms, such as ghrelin, glucagon-like peptide, glucose-dependent insulinotropic polypeptide, or the inhibitory peptide somatostatin...

OBJECTIVES: According to a report by the United States National Health and Nutrition Examination Survey, nearly 60% of patients with diabetes have more than one complication caused by chronic diabetes. Type 2 diabetes is a multifactorial metabolic disorder that accounts for more than 95% of people with diabetes and usually requires multitargeted therapeutic interventions. It arises due to insufficient insulin secretion or its action or both. Recently, we reported that the oral administration of gymnemic acid, trigonelline and ferulic acid in the ratio of 2:3:1 (GTF-231), a mixture of 3 phytoingredients at a concentration of 300 mg/kg body weight significantly improved the glucose homeostasis in rats with low-dose streptozotocin-induced type 2 diabetes that were fed with high-fat diet...

Enteral nutrition is preferred over parenteral nutrition as a result of the greater safety of enteral nutrition therapy and comparative convenience. A wide variety of enteral nutrition products have been developed, including disease-specific products to help manage the nutritional needs of patients with kidney failure, liver failure, lung disease, diabetes, and other conditions. An assessment of each patient's nutritional needs and digestive function should be conducted prior to initiation of enteral nutrition therapy...

Exocrine pancreatic insufficiency (EPI) is characterized by a deficiency of exocrine pancreatic enzymes, resulting in deficits in digestion of all macronutrients, with deficiencies in digestion of fats being the most clinically relevant. The leading cause of EPI is chronic pancreatitis. However, many other causes and conditions may be implicated, including cystic fibrosis, pancreatic duct obstruction, gastric and pancreatic surgery, diabetes mellitus and other conditions. Physical and biochemical causes of EPI include decreased production and secretion of lipase, increased lipase destruction, pancreatic duct obstruction, decreased lipase stimulation and degradation, as well as gastrointestinal motility disorders...

O-linked glycosylation often involves the covalent attachment of sugar moieties to the hydroxyl group of serine or threonine on proteins/peptides. Despite growing interest in glycoproteins, little attention has been directed to glycosylated signaling peptides, largely due to lack of enabling analytical tools. Here we explore the occurrence of naturally O-linked glycosylation on the signaling peptides extracted from mouse and human pancreatic islets using mass spectrometry (MS). A novel targeted MS-based method is developed to increase the likelihood of capturing these modified signaling peptides and to provide improved sequence coverage and accurate glycosite localization, enabling the first large-scale discovery of O-glycosylation on signaling peptides...

Hypertriglyceridemia (HTG) is the third most common cause of acute pancreatitis (AP). The incidence of AP is around 10-20% with levels > 2,000 mg/dL. We present here a case of a 44-year-old male with history of uncontrolled diabetes mellitus and HTG admitted with severe abdominal pain. Labs revealed elevated lipase and amylase. CT of abdomen with contrast showed AP. He was found to have a triglyceride (TG) level of 6,672 mg/dL. Besides conventional treatment for AP with intravenous (IV) hydration, he was started on IV regular insulin along with dextrose saline...

GPR119 belongs to the G protein-coupled receptor family, and exhibits dual modes of action upon ligand-dependent activation: pancreatic secretion of insulin in a glucose-dependent manner, and intestinal secretion of incretins. Hence, GPR119 has emerged as a promising target for treating type 2 diabetes mellitus without causing hypoglycemia. However, despite continuous efforts by many major pharmaceutical companies, no synthetic GPR119 ligand has been approved as a new class of anti-diabetic agents thus far, nor has one passed beyond phase II clinical studies...
