In vitro Digestibility of Cereal and Legume (Phaseolus vulgaris) Starches by Bovine, Porcine and Human Pancreatic α‐Amylases : Effect of Dietary Fiber

The effect of heat treatment and dietary fiber from whole and dehulled black bean (Phaseolus vulgaris) seeds on digestibility of various starches by bovine, porcine and human pancreatic α‐amylases was studied. Corn, rice, wheat and black bean starch digestibility increased after heating. The degree of hydrolysis of black bean starch ranged between 56 and 83% of the values obtained for cereal starc

Effect of indigestible residue from foodstuffs on trypsin and pancreatic α‐amylase activity in vitro

Indigestible residues from black beans (B; Phaseolus vulgaris L cv Tacarigua), green beans (G; Phaseolus vulgaris L), carrots (C; Daucus carota L) and rice bran (R; from Oryza saliva L) were prepared by the pepsin/pancreatin method of Hellendoorn et al and their effect on trypsin and pancreatic α‐amylase was evaluated comparing two experimental procedures. When the remaining caseinolytic enzyme ac

Subtilisin inhibitors in Canavalia and Vicia faba seeds. A comparative study

Subtilisin isoinhibitors (SI) were isolated from jack bean (Canavalia ensiformis L) and broad bean (Vicia faba L) seeds. Jack beans contain three isoinhibitors (pI 6.6, 6.3 and 6.0) that constitute 0.021 g per 100 g of dry seeds, while the two active proteins from broad beans (pI 5.7 and 5.1) represent 0.028%. The molecular weight, determined by gel filtration, is around 8000 D in both legumes. La

Dietary fiber content and starch digestibility in cassava bread

Insoluble and soluble dietary fiber was evaluated according to the procedure of Asp et al., in cassava bread samples from different regions of Venezuela. The values for insoluble fiber were between 4.92 and 5.67% while soluble fiber ranged between 3.40 and 3.78% (dry basis). The starch content of cassava bread samples varied between 86.5 and 88.7% (dry basis). Cassava bread starch showed an elevat

Subtilisin inhibitors in legume seeds.

Subtilisin inhibitors (SI) having an average molecular mass of 8 kDa purified from jack beans (Canavalia ensiformis) and broad beans (Vicia faba) to electrophoretical homogeneity are compared to those isolated from chick peas (Cicer arietinum) and black beans (Phaseolus vulgaris). The specificity spectrum of SI is restricted to microbial serine proteinases. Their interaction with subtilisin Carlsb

Subtilisin inhibitors from legume seeds : A purification procedure

Subtilisin inhibitors were prepared from ethanol‐acetone precipitated seed extracts of chick peas, jack beans and broad beans, heated to destroy endogenous proteases. Trypsin inhibitors were complexed with trypsin and separated from subtilisin inhibitors by molecular sieve chromatography. The eluates were again heated to avoid tryptic degradation. The procedure was easy to handle and gave satisfac

Point of no return – absence of returning birds in the otherwise philopatric willow warbler Phylloscopus trochilus

The return of individual birds to a specific area in successional years, i.e. philopatry, is a remarkable behavioural trait. Here we report on the remarkably reversed: the complete absence of returning individuals of a migratory passerine with otherwise pronounced philopatry. At a high latitude study site in Abisko (68°32ʹN, 18°80ʹE) in northern Sweden none of the banded adult willow warblers Phyl

Problems and possibilities in recognition of prior learning : A critical social theory perspective

This chapter argues for the importance of understanding recognition of prior learning (RPL) through the critical social theories of Jürgen Habermas and Axel Honneth. Results from a research project exploring RPL for the accreditation of prior experiential learning in the healthcare sector in Sweden are used to develop the analysis. It is argued that RPL for accreditation could, by reflecting the r

Altered biventricular hemodynamic forces in patients with repaired tetralogy of Fallot and right ventricular volume overload because of pulmonary regurgitation

Intracardiac hemodynamic forces have been proposed to influence remodeling and be a marker of ventricular dysfunction. We aimed to quantify the hemodynamic forces in repaired tetralogy of Fallot (rToF) patients to further understand the pathophysiological mechanisms as this could be a potential marker for pulmonary valve replacement (PVR) in these patients. Patients with rToF and PR>20% (n=18) and

Independent validation of metric optimized gating for fetal cardiovascular phase-contrast flow imaging

PURPOSE: To validate metric optimized gating phase-contrast MR (MOG PC-MR) flow measurements for a range of fetal flow velocities in phantom experiments. 2) To investigate intra- and interobserver variability for fetal flow measurements at an imaging center other than the original site.METHODS: MOG PC-MR was compared to timer/beaker measurements in a pulsatile flow phantom using a heart rate (∼145

Location of myocardium at risk in comparison between single photon emission computed tomography, magnetic esonance imaging and electrocardiography

The aim of the present study was to test the hypothesis that perfusion SPECT, estimation of regional wall thickening using MRI and the distribution of ST changes on the admission ECG display similar localization of the MaR in patients with reperfused first-time MI. Eleven patients with first-time MI with ST-elevation underwent percutaneous coronary intervention (PCI), SPECT imaging within 3 hours

Estimation of area at risk in myocardial infarction

This study presents a new method for estimation and imaging of the area at risk (AaR) in myocardial infarction (MI). The values of the ST-segment deviations of 12-lead ECG signal were used as input parameters. Based on DECARTO model, the spherical surface was chosen as a reference surface to approximate the ventricular wall. On this surface, the spatial ST vector was projected. The center of AaR w

Reclaiming Polytechneio : beyond binary interpretations of a black-and-white mural

The campus of the National Metsovian Polytechnic in central Athens (henceforth Polytechneio), which was constructed in the late 19th century, has been a significant cornerstone in the sociopolitical landscape of the city. Within the history of modern Greece, Polytechneio is regarded as a symbol of resistance against the Greek military dictatorship (junta) in 1973. The surrounding wall of Polytechn
