OBJECTIVE To determine whether aerobic fitness is more salient than weight status in predicting performance on standardized math and reading tests in fourth- to eighth-grade students. STUDY DESIGN A cross-sectional study of data abstracted from 11,743 students in 47 public schools. Aerobic fitness was defined by entering the healthy fitness zone of(More)
Glyoxalase 1 (Glo1) has been implicated in anxiety-like behavior in mice and in multiple psychiatric diseases in humans. We used mouse Affymetrix exon arrays to detect copy number variants (CNV) among inbred mouse strains and thereby identified a approximately 475 kb tandem duplication on chromosome 17 that includes Glo1 (30,174,390-30,651,226 Mb; mouse(More)
CONTEXT There is a controversy regarding the definition of vitamin D insufficiency as it relates to bone health. OBJECTIVE The objective of the study was to examine the evidence for a threshold value of serum 25-hydroxyvitamin D (25OHD) that defines vitamin D insufficiency as it relates to bone health. DESIGN AND PARTICIPANTS This was a cross-sectional(More)
AIMS The aim of this study is to quantify visual field defects after temporal lobectomy for mesial temporal sclerosis and to establish eligibility for driving. METHODS Automated static perimetry was performed on 14 patients who had undergone anterior temporal lobectomy for mesial temporal sclerosis. Perimetry consisted of monocular Humphrey Field Analyser(More)
The aim of this study was to assess the eligibility to drive in patients with mesial temporal sclerosis who undergo anterior temporal lobectomy. The two major determinants in a patient's ability to drive after such surgery are visual field defects and their seizure frequency. Thirteen patients were selected. The postoperative seizure frequency was assessed(More)
We have evaluated our experience with computerized tomography and ultrasonography guided percutaneous drainage of extrahepatic abdominal fluid collections in a group of 22 patients. The most common goal was to avoid or delay surgery on abdomens in which reoperation would be difficult, mainly in high-risk patients. Drainage of pancreatic fluid collections or(More)
Cell penetrating peptides facilitate efficient intracellular uptake of diverse materials ranging from small contrast agents to larger proteins and nanoparticles. However, a significant impediment remains in the subsequent compartmentalization/endosomal sequestration of most of these cargoes. Previous functional screening suggested that a modular peptide(More)
OBJECTIVE We sought to determine whether the utilization of a respiratory therapist (RT) driven mechanical ventilation weaning protocol is associated with improvement in clinical outcomes in subjects with simple versus difficult weaning. METHODS This was a retrospective analysis of prospectively collected data obtained during a quality improvement(More)
OBJECTIVE To develop a searchable database of educational technologies used at schools and colleges of pharmacy. METHODS A cross-sectional survey design was used to determine what educational technologies were being used and to identify an individual at each institution who could serve as an information resource for peer-to-peer questions.
