The T cell receptor (TCR) and associated CD3gammaepsilon, deltaepsilon, and zetazeta signaling dimers allow T cells to discriminate between different antigens and respond accordingly, but our knowledge of how these parts fit and work together is incomplete. In this study, we provide additional evidence that the CD3 heterodimers congregate on one side of the(More)
PURPOSE To investigate the association between ultrasound energy, expressed as cumulative dissipated energy (CDE), and changes in intraocular pressure (IOP) after uncomplicated cataract surgery by phacoemulsification. METHODS In this prospective study, nonglaucomatous subjects underwent cataract surgery by phacoemulsification. IOP was compared by(More)
INTRODUCTION Due to the high incidence of headaches and pituitary tumors, neurosurgeons often evaluate patients with benign-appearing sellar lesions and headaches without insight into whether the headache is attributable to the lesion. We sought to evaluate the incidence of headache as a presenting complaint in patients undergoing transsphenoidal surgery(More)
BACKGROUND The recommendation for population- based cystic fibrosis (CF) carrier screening by the American College of Medical Genetics for the 25 most prevalent mutations and 6 polymorphisms in the CF transmembrane regulatory gene has greatly increased clinical laboratory test volumes. We describe the development and technical validation of a DNA chip in a(More)
PURPOSE To determine the carrier frequency of the 3199del6 cystic fibrosis (CF) mutation in individuals heterozygous for I148T in a large-scale CF testing population. METHODS DNA samples from 439 consecutive I148T-heterozygous individuals were screened for the 3199del6 mutation using a laboratory-developed test. RESULTS Genotyping revealed four samples(More)
Non-visual gaze patterns (NVGPs) involve saccades and fixations that spontaneously occur in cognitive activities that are not ostensibly visual. While reasons for their appearance remain obscure, convergent empirical evidence suggests that NVGPs change according to processing requirements of tasks. We examined NVPGs in tasks with long-term memory (LTM) and(More)
PURPOSE To investigate the association between oral contraceptive (OC) use and glaucoma prevalence in the United States. DESIGN Cross-sectional study. PARTICIPANTS A total of 3406 female participants, aged 40 years or older, from the 2005 to 2008 National Health and Nutrition Examination Survey, who reported a presence or absence of glaucoma or ocular(More)
Glioblastoma is the most common malignant brain tumor, and it carries an extremely poor prognosis. Attempts to develop targeted therapies have been hindered because the blood-brain barrier prevents many drugs from reaching tumors cells. Furthermore, systemic toxicity of drugs often limits their therapeutic potential. A number of alternative methods of(More)
We discuss methods for fast spatiotemporal smoothing of calcium signals in dendritic trees, given single-trial, spatially localized imaging data obtained via multi-photon microscopy. By analyzing the dynamics of calcium binding to probe molecules and the effects of the imaging procedure, we show that calcium concentration can be estimated up to an affine(More)
PURPOSE Genotyping 37,026 individuals as part of a thrombophilia evaluation, we determined and analyzed the genotypic frequencies of the 677CT and 1298AC mutations in the methylenetetrahydrofolate reductase (MTHFR) gene. METHODS The 677CT and 1298AC mutations in the MTHFR gene were determined by either a laboratory-developed test involving PCR(More)
