The aim of this study was to investigate the Lewis antigen expression in Helicobacter pylori gastric MALT lymphoma associated strains in comparison to chronic gastritis only strains. Forty MALT strains (19 cagPAI (-) and 21 cagPAI (+)) and 39 cagPAI frequency-matched gastritis strains (17 cagPAI (-) and 22 cagPAI (+)) were included in this study. The lipopolyssacharide for each strain was extra...

Primary mucosa-associated lymphoid tissue (MALT) lymphoma arising in the common bile duct (CBD) is extremely rare. In our case of MALT lymphoma, CT and MRI showed long, segmental, irregular wall thickening of the CBD and minimal dilatation of the upstream bile duct. A preoperative diagnosis of cholangiocarcinoma was made, but histologic evaluation confirmed MALT lymphoma of the CBD. We herein p...

We characterized the interactions of various compounds with OAT-K1 and OAT-K2, kidney-specific organic anion transporters. By using Madin-Darby canine kidney cells stably transfected with OAT-K1 or OAT-K2 cDNA, the antitumor drug methotrexate, the mycotoxin ochratoxin A, endogenous organic anions (thyroid hormones, taurocholic acid, and conjugated steroids), and the antiretroviral drug zidovudi...

The aim of this study was to evaluate the potential of kefir production using cow-oat milk mixture. Therefore kefir samples with 20, 40 and 60 % of oat milk were produced. The effect of oat-milk ratio on physicochemical, rheological, microbiological and sensory characteristics of the kefir samples was studied during 21 days storage at refrigerated conditions. Increasing oat milk concentration a...

Ornithine aminotransferase (OAT) is a reversible enzyme expressed mainly in the liver, kidney and intestine. OAT controls the interconversion of ornithine into glutamate semi-aldehyde, and is therefore involved in the metabolism of arginine and glutamine which play a major role in N homeostasis. We hypothesised that OAT could be a limiting step in glutamine-arginine interconversion. To study th...

microRNAs (miRNAs) are small non-coding RNAs that can function as endogenous silencers of target genes and play critical roles in human malignancies. To investigate the molecular pathogenesis of gastric mucosa-associated lymphoid tissue (MALT) lymphoma, the miRNA expression profile was analyzed. miRNA microarray analysis with tissue specimens from gastric MALT lymphomas and surrounding non-tumo...

Emollients are recommended by international guidelines as first-line agents in the management of atopic dermatitis (AD), which occurs in 10–20% of children in the western countries (1). They improve the cutaneous barrier function and reduce xerosis (1) and some of them, which contain oat extracts, display anti-inflammatory properties (2) and may reduce steroid consumption when used as adjuvants...

Oat flour, the by-product resulting from commercial production of oat bran, was analyzed to contain 7.7% moisture, 11% CP, 6% crude fat, 8.8% NDF, 1.56% ash (.10% Ca, .23% P), 4,265 kcal/kg GE, .41% lysine, .36% threonine, .17% tryptophan, .21% methionine and .34% cystine. Chick bioassays revealed that lysine and threonine were the first- and second-limiting amino acids in oat flour. Slope-rati...

Increased synthesis of ornithine aminotransferase [EC 2.6.1.13] (OAT) in the kidney of pyridoxine-deficient rats has been reported previously (Ikeda, M. and Okada, M. (1985): J. Nutr. Sci. Vitaminol., 31, 553-561). In this report the effects of 3,3',5'-triiodothyronine (T3) and estradiol on OAT activity in the kidney of rats given pyridoxine-deficient and control diets were studied. T3 induced ...

T(11;18)(q21;q21) is the most common structural abnormality in extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) leading to the fusion of the apoptosis inhibitor-2 (API2) gene and the MALT lymphoma-associated translocation (MALT1) gene. In 2 patients with MALT lymphoma of the liver and skin, respectively, t(14;18)(q32;q21) was observed by cytogenetic ...
