Optimization of nutritional strategies using a mechanistic computational model in prediabetes: Application to the J-DOIT1 study data.

Lifestyle interventions have been shown to prevent or delay the onset of diabetes; however, inter-individual variability in responses to such interventions makes lifestyle recommendations challenging. We analyzed the Japan Diabetes Outcome Intervention Trial-1 (J-DOIT1) study data using a previously published mechanistic simulation model of type 2 diabetes onset and progression to understand the causes of inter-individual variability and to optimize dietary intervention strategies at an individual level. J-DOIT1, a large-scale lifestyle intervention study, involved 2607 subjects with a 4.

Adenosquamous carcinoma coexisting with intraductal papillary mucinous neoplasm of the pancreas: a case report.

Background: Adenosquamous carcinoma of the pancreas is a rare variant, with a worse prognosis than pancreatic ductal adenocarcinoma; moreover, it has characteristic clinical and histopathological features. Studies have mentioned the differentiation of intraductal papillary mucinous neoplasms into mucinous/tubular adenocarcinomas; however, their transdifferentiation into adenosquamous carcinoma remains unclear.

Case Presentation: An 80-year-old Japanese woman was referred to our hospital for further examination of multiple pancreatic cysts.

Suppressed levels of growth hormone and insulin-like growth factor-1 during successful pregnancy in persistent acromegaly.

Pregnancy is a rather rare event in acromegaly because fertility is often reduced during active disease. Previous reports of pregnancy in acromegalic patients showed that the pituitary growth hormone (GH) level was unaffected and the insulin-like growth factor (IGF)-1 level was elevated during the second and third trimesters. We describe here a case of persistent acromegaly that showed suppressed levels of GH and IGF-1 during pregnancy.

Small dense LDL-cholesterol relative to LDL-cholesterol is a strong independent determinant of hypoadiponectinemia in metabolic syndrome.

Background: Small dense low-density lipoprotein (sd-LDL) is an atherogenic lipoprotein closely associated with an increased risk of cardiovascular diseases. However, a precise analysis of the actual amount of sd-LDL-cholesterol (sd-LDL-C) in patients with metabolic syndrome (MS) has not been performed.

Methods And Results: Among 214 patients enrolled in the present study, 101 patients (47%) met the Japanese MS criteria.

Increased adiponectin secretion by highly purified eicosapentaenoic acid in rodent models of obesity and human obese subjects.

Objectives: Fish oil rich in n-3 polyunsaturated fatty acids (PUFAs) or n-3 PUFAs have been shown to reduce the incidence of coronary heart disease. Here we investigated the effect of highly purified eicosapentaenoic acid (EPA) on production of adiponectin, the only established antiatherogenic and antiinflammatory adipocytokine, in rodent models of obesity and human obese subjects.

Methods And Results: We demonstrated that EPA increases adiponectin secretion in genetically obese ob/ob mice and high-fat diet-induced obese mice.

An alpha-glucosidase inhibitor, voglibose, reduces oxidative stress markers and soluble intercellular adhesion molecule 1 in obese type 2 diabetic patients.

Postprandial hyperglycemia and hyperlipidemia are considered risk factors for cardiovascular disease. This study was designed to elucidate whether improving the postprandial state by voglibose, an alpha-glucosidase inhibitor, leads to the reduction of oxidative stress markers and soluble adhesion molecules in obese type 2 diabetic patients. A total of 30 Japanese obese type 2 diabetic patients were randomly assigned and treated for 3 weeks with either diet alone (the control group) or diet plus voglibose (0.

Antidiabetic effects of dietary administration of Aloe arborescens Miller components on multiple low-dose streptozotocin-induced diabetes in mice: investigation on hypoglycemic action and systemic absorption dynamics of aloe components.

We carried out three experimental trials to determine antidiabetic effects of Aloe arborescens Miller components. Firstly, ICR mice which received frequent injections of streptozotocin (Sz) in small doses (low-dose Sz-induced diabetes mice) were fed ad libitum with basal diets supplemented with components of Aloe arborescens Miller var. natalensis Berger (Kidachi aloe) and Aloe vera Linne from 31 days before to 73 days after the Sz injections.

Inhibitory effects of aloe carboxypeptidase fraction on streptozotocin-induced enhancement of vascular permeability in the pancreatic islets.

The protective actions of components isolated from Aloe arborescens Miller var. natalensis Berger (Kidachi aloe in Japanese) on streptozotocin (Sz)-induced necrosis of B cells in the pancreatic islets of the mouse were investigated to clarify its action mechanism involved in anti-diabetic effects. In this experiment, phenol low molecular weight components of aloin and aloin A that were anti-oxidants and derived from the leaf skin or pulp extract, an aloe carboxypeptidase fraction that is a inhibitor of enhanced vascular permeability and a glycoprotein component that decreases blood glucose were tested with mice precedently administered with Sz which is known as a cytotoxin specific to B cells.
