Background: Motile sperm is essential for successful embryo production. The aim of the present study was to compare the in vitro embryo development following isolation of Ram epididymal sperm isolation by swim up (SP) or Histoprep® continuous gradient (HP). Materials and Methods: Ram testes-epididymis were provided from the local slaughterhouse and transported to the lab. Sperms were recovered ...

PURPOSE To estimate the incidence of hypertensive phase (HP) following silicone plate Ahmed glaucoma valve implantation and to explore the risk factors for developing HP. METHODS A total of 325 eyes from 325 patients who underwent Ahmed glaucoma valve implantation for uncontrolled intraocular pressure (IOP) and were followed for at least 1 year were included. The HP was defined as IOP>21 mm H...

This study evaluated the effect of physical and chemical activation on the diffusion time of different concentrations of hydrogen peroxide (HP) bleaching agents through enamel and dentin. One hundred and twenty bovine cylindrical specimens were divided into six groups (n = 20): 20% HP; 20% HP with light activation; 20% HP with manganese gluconate; 35% HP; 35% HP with light activation; and 35% H...

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, ...
