We synthesized PYY-(1-36) (nonselective between Y(1) and Y(2) receptor subtype agonists), [Pro(34)]PYY (selective for Y(1)), and PYY-(3-36) (selective for Y(2)) to determine whether solution conformation plays a role in receptor subtype selectivity. The three peptides exhibited the expected specificities in displacing labeled PYY-(1-36) from cells transfected with Y(1) receptors (dissociation c...
Hematopoietic progenitor cells migrate in vitro and in vivo towards a gradient of the chemotactic factor stromal cell-derived factor-1 (SDF-1) produced by stromal cells. This is the first chemoattractant reported for human CD34 1 progenitor cells. Concentrations of SDF-1 that elicit chemotaxis also induce a transient elevation of cytoplasmic calcium in CD34 1 cells. SDF-1-induced chemotaxis is ...
BACKGROUND Assays for IgG antibodies against deamidated gliadin (IgG-anti-dGli) are comparable in performance with tests detecting IgA antibodies against tissue transglutaminase (IgA-anti-tTG) in diagnosing celiac disease (CD). IgA-anti-tTG are absent in IgA deficiency, a condition often associated with CD. In IgA deficiency, IgG-anti-tTG, which have a lower overall diagnostic accuracy, are rou...
BACKGROUND Treatment of celiac disease (CD) is based on the avoidance of gluten-containing food. However, it is not known whether trace amounts of gluten are harmful to treated patients. OBJECTIVE The objective was to establish the safety threshold of prolonged exposure to trace amounts of gluten (ie, contaminating gluten). DESIGN This was a multicenter, double-blind, placebo-controlled, ra...
The aim of this study was to compare the morphological features rat femoral bone regeneration during intramedullary osteosynthesis using medical steel and carbon-carbon composite material. Materials methods. All animals were divided into two groups. A fracture thighbone simulated by surgical intervention. In first group, used for fixation fragments; in second fragments fixed a morphological, mo...
The adhesion of activated neutrophils to endothelial cells is a key feature of the inflammatory response to cardiopulmonary bypass (CPB) because it "unlocks" a cascade of cytotoxic events. This adhesion is made possibly by the sequential involvement of two sets of neutrophil cell surface receptors: L-selection and beta 2 integrins (CD 11 a/CD 18; CD 11 b/CD 18; CD 11 c/CD 18). We have assessed ...
در دهههای اخیر رشد صنعت سبب افزایش آلودگی خاکهای کشاورزی به فلزات سنگین شده است و استفاده از قارچ میکوریزا میتواند بر نحوه جذب این فلزات به گیاه تأثیرگذار باشد. لذا این تحقیق با استفاده از گیاه ذرت در شرایط گلخانهای با دو فاکتور کادمیوم (شامل سطوح صفر، mg Cd kg-150 با پلیمر Poly-hydroxybutanamide و mg Cd kg-150 با نیترات کادمیوم) و فاکتور قارچ (با قارچ میکوریزا Glomus Caledonium و بدون قارچ...
Human natural killer INK) cells are bone marrow (BM)-derived CD2+CD16+CD56+ large granular lymphocytes (LGL) that lack CD3 yet contain the T-cell receptor (-chain (c-TCR). NK cells provide requisite interferon-y (IFN-y) during the early stages of infection in several experimental animal models. A number of studies have shown that human CD3-CD56' NK cells can be obtained from BM-derived CD34+ he...
