OATS AND FAT-FREE MILK BASED FUNCTIONAL FOOD PRODUCT

2001

The present study addresses problems and solutions related to new functional bio-active food product creation. Commercial rolled oats and fat-free milk were used as raw materials. Limited enzymatic hydrolysis of oat starch was carried out by α-amylase. The lactic acid bacteria strains Lactobacillus acidophilus, Bifidobacterium sp., and commercial starter cultures ABT-1 were cultivated in enzymatically hydrolysed oat mash. Lactobacillus acidophilus was a more active producer of lactic acid, while Bifidobacterium sp. improved the taste properties. A fat-free milk additive was applied to stabilise the texture of the oat mash, and increase the protein content of the final product. All procedure…

Bifurcation method of stability analysis and some applications

2014

In this paper a new approach to the analysis of implicitly given function- als is developed in the frame of elastic stability theory. The approach gives an effective procedure to analyse stability behaviour, and to determine the bifur- cation points. Examples of application of the proposed approach for analysis of stability are presented, more precisely we consider the stability problem of an axially moving elastic panel, with no external applied tension, performing transverse vibrations. The analysis is applicable for many practical cases, for example, paper making and band saw blades.

A NEW PHOTOGRAMMETRIC LAYOUT OF CAMERA STATIONS: A CASE STUDY

2015

This paper describes an easy and low cost photogrammetric method to determine the height of a point in relation to a reference plane. Such a method consists of an innovative geometric layout of the camera stations and specific algorithms. It is applicable to architectural surveying, in particular when the surface to be surveyed present a definitive geometry, with clearly identifiable defined points. The effectiveness of this method was verified through a case study carried out with the use of a digital camera and three dimensional targets. Two different pairs of images were obtained. One pair consists of images taken with a 35 mm and 19 mm focal length; the other one consists of images take…

Bifocal stimulation in patient with congenitally corrected transposition of great vessels

2012

Congenitally corrected transposition of the great vessels (CCTGV) is a rare congenital heart defect associated with multiple cardiac morphological abnormalities and conduction defects. Complete atrioventricular (AV) block occurs in 30% of patients and it may be present at birth or develop later with a rate of 2% per year; moreover, a systemic right ventricle is frequently characterized by heart failure in adult life. We used a bifocal cardiac stimulation for a young woman affected by CCTGV and atrioventricular Mobitz 2 and 2:1 block, considering structural, anatomic condition, and the high rate of pacing she underwent

Mini-Crush Versus T-Provisional Techniques in Bifurcation Lesions. Clinical and Angiographic Long-Term Outcome After Implantation of Drug-Eluting Ste…

2009

Objectives: This retrospective study sought to assess the clinical and angiographic long-term outcome after implanting drug-eluting stents in bifurcation lesions with the T-provisional (T-prov) technique and mini-crush (MC) technique. Background: The best option on the treatment of coronary bifurcation lesions is a subject of considerable debate. However, recent evidence suggests that bifurcation lesions might be treated by drug-eluting stent on both branches using the MC technique with a low rate of major adverse cardiac event and restenosis. Methods: From April 2004 to July 2006, 457 patients were consecutively treated with either MC technique (n = 199) or T-prov technique (n = 258). Of t…

Ferritin synthesis by Caco-2 cells as an indicator of iron bioavailability: Application to milk-based infant formulas

2007

The bioavailability of iron from milk-based infant formulas was estimated by an in vitro system including enzymatic digestion, iron uptake by Caco-2 cells and ferritin determination via an enzymoimmunoassay (ELISA). Positive correlations (p < 0.01) were found between the Fe(II) added to Caco-2 cells and ferritin synthesis and between the amount of dialyzed iron added to the cell culture and ferritin synthesis. The comparison of the bioavailability of iron from different milk-based formulas showed that adapted formulas having the same composition but differing in the iron salts added yielded similar ferritin levels. The same happened with follow-up formulas differing only in the presence or …

Distribution of aquatic Oligochaeta in the Finnish Lake District

1980

SUMMARY. The distribution of oligochaetes was examined at sampling stations grouped into three types: (1), in eutrophic and dystrophic areas or in areas polluted by pulp-mill wastewaters; (2), slightly eutrophic stations; (3), ‘clean’ stations unaffected by sewage or other inputs. Limnodrilus hoffmeisteri and Potamothrix hammoniensis were practically the only species in group 1, and the same species accounted for two thirds of the total numbers in group 2, although Peloscolex ferox and some other species also occurred. At the cleanest stations the dominating species were P. ferox, Psammoryctides barbatus, Stylodrilus heringianus and Tubifex tubifex. A factor analysis showed that L. hoffmeis…

T cell specificity and cross reactivity towards enterobacteria,Bacteroides,Bifidobacterium, and antigens from resident intestinal flora in humans

1999

BACKGROUNDT cell responses to normal intestinal bacteria or their products may be important in the immunopathogenesis of chronic enterocolitis.AIMSTo investigate the T cell specificity and cross reactivity towards intestinal bacteria.PATIENTS/METHODST cell clones were isolated with phytohaemagglutinin from peripheral blood and biopsy specimens of inflamed and non-inflamed colon from five patients with inflammatory bowel disease (IBD) and two controls. T cell clones were restimulated with anaerobicBacteroides andBifidobacteria species, enterobacteria, and direct isolates of aerobic intestinal flora. T cell phenotype was analysed by single-cell immunocyte assay.RESULTSAnalysis of 96 T cell cl…

Reversible self-assembly of metal chalcogenide/metal oxide nanostructures based on Pearson hardness.

2010

Nanotechnology has reached a stage of development where not individual nanoparticles but rather systems of greater complexity are the focus of concern. These complex structures incorporate two or more types of materials, an example of which is the formation of metal–semiconductor hybrids, which effectively combine the properties of both materials. The assembly of multicomponent nanoparticles from constituents with different optical, electrical, magnetic, and chemical properties can lead to novel functionalities that are independent of the individual components and may be tailored to fit a specific application. These applications include such far-reaching challenges as solar energy conversio…
