We have developed a procedure to predict the output signal and system noise of various scintillator/photodiode detector combinations. The simulation is in three parts: 1. Monte Carlo techniques are used …more
A new functional magnetic resonance imaging (fMRI) technique for simultaneous detection (SIDE) of changes in perfusion and blood oxygenation level dependent (BOLD) contrast is described. Perfusion contrast is generated by …more
SPADE is a new acquisition scheme for fMRI based on dual echo EPI. As In previous work. additional spin echo EPI images are used to recover signal in regions that …more
While the fMRI test-retest reliability has been mainly investigated from the point of view of group level studies, here we present analyses and results for single-subject test-retest reliability. One important …more
Common variants at only two loci, FTO and MC4R, have been reproducibly associated with body mass index (BMI) in humans. To identify additional loci, we conducted meta-analysis of 15 genome-wide …more
BACKGROUND: Exercise tolerance in COPD is only moderately well predicted by airflow obstruction assessed by FEV(1). We determined whether other phenotypic characteristics, including CT scan measures, are independent predictors of …more
Cerebellar volumes show small positive correlations with cognitive ability in young adults, but no studies have examined this relationship in older adults. Furthermore, no studies have examined relationships between sizes …more
An estimate of someone’s IQ is a potentially informative personal datum. This study examines the association between external skull measurements and IQ scores, and uses the resulting regression equation to …more
Context: Studies in animals suggest that the limbic prefrontal cortex, including the anterior cingulate cortex, is involved in regulation of the hypothalamic-pituitary-adrenal (HPA) axis, but human data are lacking. Objective: …more
RATIONALE/OBJECTIVES: Smoking has been associated with decreased incidence and prevalence of sarcoidosis, but few studies have evaluated effects of smoking on clinical parameters of the disease. The objectives were to …more
Behavioral studies have shown that, at a population level, women perform better on tests of social cognition and empathy than men. Furthermore Autism Spectrum Disorders (ASDs), which are characterized by …more
In the title type B-2 acid salt, Na(LH)(LH2) . H2O [LH2 = C2H4C(CO2H)(2)] or Na+ . C5H5O4-.C5H6O4 . H2O, the vertices of a distorted octahedron centred on each Na+ cation …more
