Understanding the implementation of evidence-based practice (EBP) in community service settings is critical for the successful translation of research to practice. However, we have limited research evidence about the impact of EBP implementation on the mental health and social service workforce. In a previous study we demonstrated reduced staff turnover(More)
We examined the effects of a pentadecapeptide having the 104-118 aminoacid sequence of islet neogenesis-associated protein (INGAP-PP) on insulin secretion, and the morphological characteristics of adult and neonatal pancreatic rat islets cultured in RPMI and 10 mM glucose for 4 days, with or without different INGAP-PP concentrations (0.1-100 mug/ml). A(More)
The aim of the present study was to test the effect of sitagliptin and exendin-4 upon metabolic alterations, β-cell mass decrease and hepatic steatosis induced by F (fructose) in rats. Normal adult male Wistar rats received a standard commercial diet without (C) or with 10% (w/v) F in the drinking water (F) for 3 weeks; animals from each group were randomly(More)
Limited organ availability is an obstacle to the widespread use of islet transplantation in type 1 diabetic patients. To address this problem, many studies have explored methods for expanding functional human islets in vitro for diabetes cell therapy. We previously showed that islet cells replicate after monolayer formation under the influence of hepatocyte(More)
The effect of 2-deoxy-D-glucose tetraacetate upon glucose-stimulated insulin release was explored in pancreatic islets from either normal or hereditary diabetic rats. At a high concentration (10 mM), it decreased the secretory response to D-glucose, such an inhibitory effect being more marked in the case of the alpha- than beta-anomer of the ester. At lower(More)
The esterification of several monosaccharides, such as D-glucose, D-mannoheptulose and 2-deoxy-D-glucose was recently reported to increase their biological efficiency as either nutrient or antimetabolic agent. In the present study, however, the tetraacetate ester of streptozotocin was unexpectedly found to be less potent than unesterified streptozotocin in(More)
This study aimed to determine the relative importance of different functional and morphological pancreatic changes induced by the chronic administration of a sucrose-rich diet (SRD) to maintain normal glucose homeostasis. Male Wistar rats were fed either sucrose (SRD) or starch (CD) for 6 and 12 months. At both periods, serum glucose and triacylglycerol(More)
The aim of this work was to study the possible relationship between pancreatic duodenal homeobox-1 (Pdx-1) and islet neogenesis-associated protein (INGAP) during induced islet neogenesis. Pregnant hamsters were fed with (S) and without (C) sucrose, and glycemia, insulin secretion in vitro, and pancreas immunomorphometric parameters were measured in their(More)
The aim of the present study was to test the possible presence and expression of islet neogenesis-associated protein (INGAP) in islet cells of normal adult hamsters. Pancreata from normal male Syrian hamsters were removed to perform the following studies. (i) Western blot analysis using the cytosolic fraction from homogenates of isolated islets, exocrine(More)
Background: Tyrosine hydroxylase (TH) activity and its possible participation in the control of insulin secretion were studied in pancreatic islets of adult Wistar rats fed a standard commercial diet (SD) or carbohydrates alone (CHD) for one week. TH activity, norepinephrine (NE) content, and glucose-induced insulin secretion were assessed. Blood glucose(More)
