The aim of this study was to assess the association between some dietary factors and prevalence of H. pylori infection or strain virulence in 294 adult asymptomatic blood donors. Methods. Seroprevalence was evaluated using ELISA. Logistic regression was used. Results. Anti-H. pylori IgG prevalence was 72.4%, and CagA IgG seroprevalence was 49.3%. In the multivariate analyses, the frequent (>5 d...

Very simple and selective methods are presented to determine the amino acid tryptophan (Trp) and the biogenic amine tryptamine (Tryp), both compounds with an indole-type molecular structure by the methodology named Heavy Atom Induced-Room Temperature Phosphorescence (HAI-RTP) which constitutes the first time that HAI-RTP has been used to detect compounds with non-naphthalenic structures in thei...

Štern P., pokorný J., Šedivá A., Panovská Z. (2008): Rheological and sensory characteristics of yoghurt-modified mayonnaise. Czech J. Food Sci., 26: 190–198. Rheological and textural characteristics were studied in a set of 11 samples of yoghurt-modified mayonnaise at 15, 20, and 25°C. The rheometer Rheostress 300 was used to determine the static yield value, apparent viscosity, thixotropy, and...

Stirred yoghurts with different fruit homogenates (papaya, kiwi, pineapple and kaki and control (without additive) were prepared and stored up to 14 days at 5±1°C. Sugar and fruit homogenates were added at the rate of 5 and 10% w/w respectively. The results revealed that, significant differences were observed in proteolytic activity, acidity, protein and fibers contents among all treatments. Ad...

Radio frequency (RF) heating was applied to stirred yoghurt after culturing in order to enhance the shelf-life and thereby meet industrial demands in countries where the distribution cold chain cannot be implicitly guaranteed. In parallel, a convectional (CV) heating process was also tested. In order to meet consumers' expectations with regard to texture and sensory properties, the yoghurts wer...

Butyric acid (C4) and pyroglutamic (pGlu) exert significant beneficial effects on human health. In this study, the influence of probiotics (Lactobacillus acidophilus Bifidobacteria) and/or prebiotics (1 3% inulin fructo-oligosaccharides) content C4 pGlu in yoghurt during shelf-life period was evaluated. The contents were determined probiotic, prebiotic synbiotic yoghurts 30 days storage at 4 °C...

Caspian Sea yoghurt has lower acidity and is thicker than common yoghurt. contains probiotic bacteria that improve the balance of intestinal microflora. This research aimed to determine antioxidant activity sea enriched with two different herbs, ginger sappanwood, at concentrations 5, 10 15% w/v. The pH, total phenol, antioxidant, LAB, antibacterial were measured best products. results showed e...

We examined the association between community violence exposure and childhood asthma risk in a multilevel, multimethod, longitudinal study controlling for individual- and neighbourhood-level confounders and pathway variables. Analyses included 2,071 children aged 0-9 yrs at enrolment from the Project on Human Development in Chicago Neighborhoods. Multilevel logistic regression models estimated ...

Disparities in verbal ability, a major predictor of later life outcomes, have generated widespread debate, but few studies have been able to isolate neighborhood-level causes in a developmentally and ecologically appropriate way. This study presents longitudinal evidence from a large-scale study of >2,000 children ages 6-12 living in Chicago, along with their caretakers, who were followed where...
