the aim of this study was to compare the efficacy of antireflux therapy with both conventional management and those with no treatment in children with chronic otitis media with effusion (come). in this prospective randomized clinical trial ninety children with come which lasted more than 3 months or more, documented by physical examination and type b tympanogram in at least one ear without clin...
The effect of peritoneal fluid (PF) on the human sperm acrosome reaction (AR) was tested. Sperm was pre-incubated with PF and the AR was induced by calcium ionophore A23187 and a neoglycoprotein bearing N-acetylglycosamine residues (NGP). The AR induced by calcium ionophore was inhibited 40% by PF from controls (PFc) and 50% by PF from the endometriosis (PFe) group, but not by PF from infertile...
Allergic rhinitis (AR) is one of the most common chronic allergic respiratory diseases worldwide. Various practical guidelines for AR have been developed and updated to improve the care of AR patients; however, up to 40% patients remain symptomatic. The unmet need for AR care is one of the greatest public health problems in the world. The gaps between guideline and real-world practice, and diff...
Abstract. High-resolution geochronology is essential for determining the growth rate of volcanoes, which one key factors establishing periodicity volcanic eruptions. However, there are less high-resolution eruptive histories (> 106 years) determined long-lived submarine arc complexes than subaerial complexes, since volcanoes far more difficult to observe ones. In this study, and major-elemen...
(40)Ar/(39)Ar dates of emplacement-related metamorphic rocks beneath the Samail ophiolite in Oman show that cooling to <525 degrees C occurred within approximately 1 million years of igneous crystallization of the ophiolite. This unexpectedly short time span and rapid cooling means that old, cold continental or oceanic lithosphere must have been adjacent to the ophiolite during spreading and th...
Introduction: The impact history of the solar system remains controversial. Early investigation of lunar samples, returned by Apollo astronauts, led to the 'Late Heavy Bombardment' (LHB) concept [1,2] which hypothesized a sharp increase in bolide flux centered around ~3.9 Ga. Evidence for this cataclysm was first derived from whole-rock U-Pb and Rb-Sr ages [2] but subsequently more on 40 Ar-39 ...
Enzalutamide is an androgen receptor (AR) inhibitor approved for therapy of metastatic castration resistant prostate cancer. However, clinical application revealed that 30 to 40% of patients acquire resistance after a short period of treatment. Currently, the molecular mechanisms underlying such resistances are not completely understood, partly due to a lack of model systems. In the present stu...
an inversion procedure is used to obtain from the extended principle of corresponding - states the pair interaction potentials for argon, krypton and its mixture over a tetnperature range from absolute zero to the onset of ionization. the experimentally-reduced viscosity collision integrals obtained from the corresponding - states correlation have been inverted directly to give the reduced-inte...
