BACKGROUND Asthma and allergies are commonly undiagnosed in children. Schools provide settings for potentially accessing almost all children for asthma and allergy screening. OBJECTIVE To evaluate the feasibility and validity of using a questionnaire-based screening tool to identify undiagnosed asthma and respiratory allergies in children in kindergarten to grade 6. METHODS A student questi...
Despite the important discoveries reported by genome-wide association (GWA) studies, for most traits and diseases the prediction R-squared (R-sq.) achieved with genetic scores remains considerably lower than the trait heritability. Modern biobanks will soon deliver unprecedentedly large biomedical data sets: Will the advent of big data close the gap between the trait heritability and the propor...
PURPOSE The molecular drivers that determine histology in lung cancer are largely unknown. We investigated whether microRNA (miR) expression profiles can differentiate histologic subtypes and predict survival for non-small cell lung cancer. EXPERIMENTAL DESIGN We analyzed miR expression in 165 adenocarcinoma and 125 squamous cell carcinoma (SQ) tissue samples from the Environment And Genetics...
Rates of DNA repair in ultraviolet (254 nm)-irradiated nondividing human diploid fibroblasts were determined at doses as low as 1 J/sq m using an enzymatic assay for pyrimidine dimers. In normal cells, initial rates (dimers removed per 24 hr) increased with dose to 20 J/sq m with no further increase at 40 J/sq m. At 10 J/sq m or less, repair occurred continuously over long postultraviolet perio...
Background and Objective : Satisfaction is costumer response to an organization success. Costumer satisfaction is used as an important and strategic tool in organization in order to achieve competitive advantage. Thus, higher education institutes increasingly pay attention to satisfying students' expectations as primary costumers. Hence, this study was implemented in order to measure studen...
PURPOSE Sebum may contribute to the composition of the tear film lipid layer naturally or as a contaminant artifact from collection. The aims of this study were to determine: if sebum changes the rheology of meibum surface films; if the resonance near 5.2 ppm in the 1H-NMR spectra of sebum is due to squalene (SQ); and if sebum or SQ, a major component of sebum, interacts with human meibum. ME...
