OBJECTIVE To study immunization procedures and preparation methods of specific IgY antibodies (IgY-Hp, IgY-IB) produced by hens immunized with Helicobacter pylori (Hp) bacterial antigen and recombinant Hp specific antigen IB, detect the inhibition effects on Hp growth and Hp urease activity, and study the effects of oral administration for treating Hp infection. METHODS By using recombinant c...

Introduction: The competence of opiate addicts to give a valid consent to heroin prescription (HP) has been doubted in principle under the assumption that the pathological urge to use heroin would prevent them from reasonably weighing the pros and cons of HP. This study was done to test whether opiate addicts have a differentiated attitude towards HP which would be a basis for an individual dec...

Anhaptoglobinemic patients have been reported to experience severe anaphylactic reactions to transfusions due to the production of antihaptoglobin (anti-HP) antibodies (1, 2 ). Anhaptoglobinemia in patients homozygous for HP , which is a deletion of an approximately 28-kb segment of chromosome 16 extending from the promoter region of the HP (haptoglobin) gene to exon 5 of HPR (haptoglobin-relat...

blood samples were collected from the jugular vein of 101 clinically healthy iranian fat-tailed sheep according to their age (5 years) and sex. serum haptoglobin (hp) was measured based upon the preservation of the peroxidase activity of haemoglobin, which is directly proportional to the amount of hp. the reference value for serum hp of apparently healthy iranian fat-tailed sheep was 0.05-0.18 ...

twenty eight lactating buffaloes were used in a completely randomized design with 2×2 factorial arrangement of four experimental diets including low protein–low energy (lp-le), low protein–high energy (lp-he), high protein–low energy (hp-le) and high protein–high energy (hp-he). results showed that the hp-he diet recorded the highest digestibility coefficients of cp, ee, nfe, nutritive values, ...

RATIONALE Hypersensitivity pneumonitis (HP) exhibits a diverse outcome. Patients with acute/subacute HP usually improve, whereas patients with chronic disease often progress to fibrosis. However, the mechanisms underlying this difference are unknown. OBJECTIVES To examine the T-cell profile from patients with subacute HP and chronic HP. METHODS T cells were obtained by bronchoalveolar lavag...

In many bacteria, LuxS functions as a quorum-sensing molecule synthase. However, it also has a second, more central metabolic function in the activated methyl cycle (AMC), which generates the S-adenosylmethionine required by methyltransferases and recycles the product via methionine. Helicobacter pylori lacks an enzyme catalyzing homocysteine-to-methionine conversion, rendering the AMC incomple...

One is a small, portable printing calculator and the other is a hand-held version without a printer. Both versions feature a "smart" magnetic card reader, and each can run the other's programs. TWO POWERFUL NEW fully programmable per sonal calculators in the tradition of the HP-65 (the first fully programmable pocket-sized scientific calculator)1 are the pocket-sized HP-67, Fig. 1, and the HP-9...

Alzheimer's Disease (AD) is characterized by a stereotypical spatial pattern of hippocampus (HP) atrophy over time, but reliable and precise measurement of localized longitudinal change to individual HP in AD have been elusive. We present a method for quantifying subject-specific spatial patterns of longitudinal HP change that aligns serial HP surface pairs together, cuts slices off the ends of...
