Palatability and glucose, insulin and satiety responses of chickpea flour and extruded chickpea flour bread eaten as part of a breakfast.

OBJECTIVE: To determine the effect of adding chickpea flour or extruded chickpea flour to white bread on palatability and postprandial glycaemia, insulinaemia and satiety. DESIGN: A randomised, single-blind, cross-over study of four 50 g available carbohydrate breakfasts. SETTING: School of Exercise and Nutrition Sciences, Deakin University. SUBJECTS: In all, 12 healthy subjects were recruited through posted notices. Totally, 11 (nine male, two female) completed the study (mean+/-s.e.m.; age 32+/-2 y; body mass index, 24.7+/-0.8 kg/m(2)). INTERVENTION: After overnight fasting, subjects consumed a control (white) bread (WB) breakfast twice, a chickpea bread (CHB) breakfast once and an extruded chickpea bread (EXB) breakfast once. Palatability and postprandial blood glucose, insulin and satiety responses were determined. Following this, food intakes from an ad libitum buffet and for the remainder of the day were assessed. RESULTS: A trend towards a lower incremental area under the curve (IAUC) of glucose for the CHB breakfast compared to the WB breakfast was observed (P=0.087). The IAUC of insulin and insulinaemic index (II) of the CHB breakfast were higher (P<0.05) than for the WB breakfast. No differences in glycaemic index (GI), satiety response, food intake or palatability were observed. CONCLUSIONS: CHB and EXB demonstrated acceptable palatability. CHB demonstrated some hypoglycaemic effect compared to WB, but neither CHB nor EXB demonstrated effects on satiety or food intake. The hyperinsulinaemic effect of CHB observed in this study requires further investigation.

Lupin kernel fibre-enriched foods beneficially modify serum lipids in men.

OBJECTIVE: To examine the effect of a diet containing a novel legume food ingredient, Australian sweet lupin (Lupinus angustifolius) kernel fibre (LKFibre), compared to a control diet without the addition of LKFibre, on serum lipids in men. DESIGN: Randomized crossover dietary intervention study. SETTING: Melbourne, Australia--Free-living men. SUBJECTS: A total of 38 healthy males between the ages of 24 and 64 y completed the intervention. INTERVENTION: Subjects consumed an LKFibre and a control diet for 1 month each. Both diets had the same background menus with seven additional experimental foods that either contained LKFibre or did not. Depending on energy intake, the LKFibre diet was designed to contain an additional 17 to 30 g/day fibre beyond that of the control diet. RESULTS: Compared to the control diet, the LKFibre diet reduced total cholesterol (TC) (mean+/-s.e.m.; 4.5+/-1.7%; P=0.001), low-density lipoprotein cholesterol (LDL-C) (5.4+/-2.2%; P=0.001), TC: high-density lipoprotein cholesterol (HDL-C) (3.0+/-2.0%; P=0.006) and LDL-C:HDL-C (3.8+/-2.6%; P=0.003). No effects on HDL-C, triacylglycerols, glucose or insulin were observed. CONCLUSIONS: Addition of LKFibre to the diet provided favourable changes to some serum lipid measures in men, which, combined with its high palatability, suggest this novel ingredient may be useful in the dietary reduction of coronary heart disease risk.

Endoscopic ultrasound localization of a pancreatic insulinoma: case report and review of the localization techniques.

A 23-year-old male was referred to our hospital for evaluation of new-onset seizures. Signs and symptoms of neuroglycopenia, including weakness, dizziness, and confusion, appeared during fasting and resolved promptly with intravenous dextrose administration. Insulin, proinsulin, and C-peptide levels were consistent with a diagnosis of insulinoma. Screening tests for multiple endocrine neoplasia type 1 and surreptitious sulfonylurea uses were negative. Preoperative localization of the insulinoma by transabdominal ultrasonography, computed tomography, and indium-111 octreoscanning were unsuccessful. Endoscopic ultrasonography (EUS) identified a 6- to 7-mm tumor at the juncture of the head and body of the pancreas. Surgical exploration confirmed the preoperative localization, and an 8-mm tumor was simply enucleated. The patient has been free of symptoms for 18 months since surgery. This report describes the utility of EUS to localize a solitary pancreatic insulinoma and provides a comparison of EUS and other preoperative localization techniques.

Differences in myosin isoform expression in the subepicardial and subendocardial myocardium during cardiac hypertrophy in the rat.

We have investigated myosin isoform expression during progressive cardiac hypertrophy and the development of congestive heart failure in young male rats. Cardiac enlargement was produced by placing a constricting band (0.024-inch diameter) around the ascending aorta of 25-day-old animals, which resulted in progressively increased stenosis as the rat matured. A 57% and 77% cardiac hypertrophy was observed at 2 and 8 weeks, respectively, with signs of congestive failure at the latter time point. Myosin isoform expression was examined in the subendocardial and subepicardial myocardium of the left ventricle and the free wall of the right ventricle by use of native gel electrophoresis. The percentage of the V3 isoform increased dramatically in both ventricles. In the subendocardial myocardium of the left ventricle, expression of the V3 isoform increased (p less than or equal to 0.05) relative to the subepicardial myocardium at 2, 4, and 8 weeks (17.1% vs. 10.2%, 29.4% vs. 18%, and 46.6% vs. 36.2%). In addition to regional differences within a given transmural segment, we also observed a high degree of heterogeneity in myosin isoform expression throughout a given layer (particularly the subendocardial myocardium) when small (less than or equal to 10-15 mg) adjacent samples were examined. This variability illustrated a potential danger in interpretation of gel results obtained from a single small tissue sample. Thus, cardiac hypertrophy produced by pressure overload in 25-day-old rats resulted in significantly increased V3 myosin in both the left and right ventricles. Furthermore, within the hypertrophied left ventricle, the subendocardial myocardium contained a significantly greater percentage of V3 myosin than the subepicardial myocardium.(ABSTRACT TRUNCATED AT 250 WORDS)

The Nominal Group Technique for planning and problem solving.

The Nominal Group Technique is a useful planning and problem-solving process that should be part of every biocommunications manager's repertoire of group managerial skills. The NGT process is designed for those situations where individual judgments must be tapped and combined to arrive at decisions which cannot be calculated by one person. It is a problem-solving or idea-generating strategy that involves silent generation of ideas which are then recorded and ranked by the group.
