The pathophysiological role of the tumour necrosis factor (TNF) system was studied in adults (n=37) and children (n=43) non asthmatic offspring of asthmatic parents with and without bronchial hyperreactivity proved by methacholine airway challenge test. SerumTNFalpha and its soluble receptors (sTNF-R1 and R2) were determined by enzyme-linked immunosorbent(More)
The contribution of the tumor necrosis factor (TNF) system and leptin was studied in insulin resistance and neonatal development during the course of normal pregnancy and gestational diabetes mellitus (GDM). Thirty patients with GDM and their neonates (n = 30), 35 healthy pregnant women (15 in the first, nine in the second and 11 in the third trimester) and(More)
Pannon White (n=12) male rabbits (weight: 4050 to 4500 g, age: 9 months) received 2 ml of a suspension containing purified T-2 toxin by gavage for 3 days. The daily toxin intake was 4 mg/animal (0.78 to 0.99 mg/kg body weight (BW)). Control animals (n=12) received toxin-free suspension for 3 days. Since a feed-refusal effect was observed on the second day(More)
A population-based study of 7,049 index patients with multiple congenital abnormalities (MCA) born in Hungary during 1973-1982 was organized by the Hungarian Center for Congenital Anomaly Control. All clinically recognized syndromes and associations which were submitted (2,049) were accepted without any further follow-up. New or supplementary information(More)
In October and November 2004, 91 spice samples (70 ground red pepper, six black pepper, five white pepper, five spice mix and five chilli samples), the majority of which originated from commercial outlets, were analysed for aflatoxins B1, B2, G1 and G2 (AFB1, AFB2, AFG1, AFG2) and ochratoxin A (OTA) content by high-performance liquid chromatography (HPLC)(More)
AIMS The aim of the study was to analyse the role of tumour necrosis factor-alpha (TNF-alpha) in insulin resistance and endothelial dysfunction in patients with different types of obesity. PATIENTS AND METHODS Fasting serum TNF-alpha immunoreactive concentration (enzyme-linked immunosorbent assay, ELISA) and bioactivity (L929 cell cytotoxicity assay),(More)
The absorption, distribution and elimination of fumonisin B(1) (and B(2)) after oral administration of Fusarium verticillioides (MRC 826) fungal culture, mixed into the experimental feed for 10 days, was studied in weaned barrows. In order to determine the absorption of FB(1) from the feed marked by chromium oxide, a special T-cannula was implanted into the(More)
Mycotoxins produced by mould fungi can enter into the human food chain directly through foods of plant origin (cereal grains), consumer goods (coffee and bear) and indirectly through foods of animal origin (kidney, liver, milk and eggs). Mycotoxins occur in small amount in the foods; however their continuous intake even in microdoses can result in(More)
The effect of digestion methods on the determination of phosphorus in cereal lipids was reinvestigated. Samples were either digested with sulfuric acid or ashed in a muffle furnace at 600 degrees C. The standard deviation and the coefficient of variation were significantly higher for the acid-digested samples. Ashing gave more reliable results, especially(More)
There is a lack of information on the effect of swine caecal microbiota on fumonisin metabolism. In this in vitro study, the biotransformation of fumonisin B(1) (FB(1)) by the gut microbiota of adult, healthy pigs was examined. Suspensions of caecal contents and McDougall buffer solution were incubated anaerobically with pure FB(1) for 0, 12, 24, 48 and 72(More)
