We describe a multiplex reverse transcription-PCR (m-RT-PCR) assay that is able to detect and differentiate all known human parainfluenza viruses (HPIVs). Serial dilution experiments with reference strains that compared cell culture isolation and m-RT-PCR showed sensitivities ranging from 0.0004 50% tissue culture infective dose (TCID(50)) for HPIV type 4B(More)
OBJECTIVE To examine whether polymorphisms within the ESR1, FSHR, ESR2, CYP19A1, and NRIP1 genes are susceptibility factors for human male idiopathic infertility and to test the joint effects of these genes on male reproductive function. DESIGN Genetic association study of male infertility with polymorphisms, using both single-gene and multilocus(More)
BACKGROUND There is much evidence involving the KIT tyrosine kinase receptor and its ligand KITLG in the survival and proliferation of germ cells. Animal models and functional studies in humans suggest that this signalling pathway plays a role in male infertility. METHODS We studied three and two single-nucleotide polymorphisms (SNPs) (rs3819392,(More)
OBJECTIVE To determine the efficacy and safety of tadalafil when taken on demand by men with erectile dysfunction (ED) secondary to traumatic spinal cord injury (SCI). DESIGN AND SETTING Multicenter, randomized, double-blind, placebo-controlled, flexible dose-titration, parallel-group study in clinical practices in Europe. Patients Enrolled patients had(More)
Malnutrition is often present on continuous ambulatory peritoneal dialysis (CAPD), and contributes to morbidity and mortality. Diabetics (DM) have an increased risk for developing malnutrition. Our purpose was to assess the nutritional status (NS) of our CAPD population, to define NS differences between DM and nondiabetics (NoDM), and to identify NS-related(More)
BACKGROUND The benefits and risks of long-term testosterone administration have been a topic of much scientific and regulatory interest in recent years. AIM To assess long-term quality of life (QOL) and sexual function benefits of testosterone replacement therapy (TRT) prospectively in a diverse, multinational cohort of men with hypogonadism. METHODS A(More)
