BACKGROUND Recent data indicate the presence of immunomodulating properties of Helicobacter pylori (Hp) (Hp Sydney Strain-1 antigen) in an experimental model of multiple sclerosis (MS), and there are limited contradictory epidemiologic data regarding Hp serology in MS patients. METHODS The aim of this prospective, comparative study was to validate the incidence of active Hp infection by histo...

BACKGROUND Sarcopenia is associated with adverse outcomes such as physical disability, poorer quality of life, and death. Helicobacter pylori (HP) eradication increases ghrelin secretion, which may be a possible treatment for sarcopenia. We investigated whether HP eradication reduces the risk of low muscle mass (LMM), which is an integral component of sarcopenia. MATERIALS AND METHODS Healthy...

UNLABELLED Backgroud: Helicobacter pylori (Hp) rarely proliferates in patients with fundic gland polyps (FGPs). We recently found that FGPs express lysozyme, one of the natural defence substances against infection. We aimed to assess the degree of lysozyme expression in a cohort of consecutive FGPs. MATERIALS AND METHODS A total of 153 gastric biopsies were investigated: 93 with FGPs, 30 with...

OBJECTIVES Haptoglobin (Hp) phenotypes 1-1, 2-1, and 2-2 are associated with inflammatory diseases. Since their biochemical structures are rather heterogeneous, it is necessary to accurately determine the plasma Hp levels. DESIGN AND METHODS Immunodiffusion, immunoturbidimetric, and noncompetitive ELISA were conducted to determine the differences in immunoreactivity among Hp phenotypes and to...

OBJECTIVES We recently demonstrated that both 3-hydroxyphthalic anhydride (HP)- and maleic anhydride-modified chicken ovalbumin (OVA) could effectively inhibit HIV-1 infection. But because OVA may cause allergy in some human subjects, here we replaced OVA with human serum albumin (HSA) in designing a new anti-HIV-1 agent, HP-HSA, and then tested its anti-HIV-1 activity and cytotoxicity. METHO...

The human leukocyte nuclear histones can bind to haptoglobin (Hp), and thus interfere with subsequent binding of Hb. The Hp/Hb complex possesses peroxidase activity, but a Hp/histone complex does not. The inhibitory effect of histone molecules depends directly on the Hp and Hb, as well as the histone concentrations. The biological significance of the complex Hp/Hb as a measure of intravascular ...

اساس سیستم‌های تصویربرداری ایکس پس­پراکنده، پرتوهای بازگشتی هستند که در صنعت و بازرسی دارای کاربرد‌های بسیاری می‌باشند. این تصاویر برخلاف روش عبوری، مواد آلی با عدد اتمی پایین مانند مخدر منفجره پراکندگی فوتون بالا، واضح‌تر دیده می‌شوند. به علت چندگانه فوتونی معمولاً مات­شدگی دارند. پردازش خروجی می‌تواند بهبود کنتراست تشخیص کمک کند. تحقیق از وردش برای استفاده شده پرتونگاره‌های فانتوم‌هایی ارزیابی...

We design and analyze an adaptive hp-finite element method (hp-AFEM) in dimensions n = 1, 2. The algorithm consists of iterating two routines: hp-NEARBEST finds a near-best hp-approximation of the current discrete solution and data to a desired accuracy, and REDUCE improves the discrete solution to a finer but comparable accuracy. The former hinges on a recent algorithm by Binev for adaptive hp...

aim : the aim of this study was to compare the half-dose and full-dose triple therapy regimens for helicobacter pylori ( hp ) eradication in patients with end-stage renal disease. background : h. pylori is one the most important causes of dyspepsia in patients with end-stage renal disease (esrd). patients and methods : sixty-six patients with esrd were enrolled in the study with hp infection an...

This in vitro study evaluated the effect of 35% hydrogen peroxide (HP) bleaching gel modified or not by the addition of calcium and fluoride on enamel susceptibility to erosion. Bovine enamel samples (3 mm in diameter) were divided into four groups (n = 15) according to the bleaching agent: control-without bleaching (C); 35% hydrogen peroxide (HP); 35% HP with the addition of 2% calcium glucona...
