Dynamic Metabolic Imaging of Hyperpolarized [2-C-13]Pyruvate Using Spiral Chemical Shift Imaging with Alternating Spectral Band Excitation
This study introduces a sequence for three-dimensional CSI of [2-(13) C]pyruvate using spectrally selective excitation of limited frequency bands containing a subset of metabolites. Dynamic CSI data were acquired alternately…

The Acute and Chronic Effects of Alcohol Consumption on Sleep Architecture in College Aged Students
This study examined the effect of alcohol on sleep architecture in women and men aged 18 to 21 years and whether previously reported sleep architecture effects may have been as…

Association between Personality Traits and DSM-IV Diagnosis of Insomnia in Peri- and Postmenopausal Women
The aim of this study was to determine the role of personality factors in the development of DSM-IV insomnia coincident with perimenopause.

Evidence for the Role of EPHX Gene Variants in Anorexia Nervosa
To identify genetic variants associated with AN, we pursued a series of sequencing and genotyping studies focusing on the coding regions and upstream sequence of 152 candidate genes in a…

Regional Manifold Learning for Disease Classification
We use the regional manifolds as low-dimensional descriptors of high-dimensional morphological image features, which are then fed into a classifier to identify regions affected by disease.

Poor Autonomic Nervous System Functioning During Sleep in Recently Detoxified Alcohol-Dependent Men and Women
We investigated nighttime ANS functioning, and the relation between ANS activity and severity of alcohol dependence in chronic alcoholism.

Conditional Ablation of Orexin/Hypocretin Neurons: A New Mouse Model for the Study of Narcolepsy and Orexin System Function
The sleep disorder narcolepsy results from loss of hypothalamic orexin/hypocretin neurons. Although narcolepsy onset is usually postpubertal, current mouse models involve loss of either orexin peptides or orexin neurons from…

Synchrony of Anterior Cingulate Cortex and Insular-Striatal Activation Predicts Ambiguity Aversion in Individuals with Low Impulsivity
To test how dACC functional network connectivity would be modulated by uncertainty and differ between individuals, 24 healthy participants underwent functional MRI in 3 sequential runs: 1 resting-state and 2…

Uncovering Cryptic Glycan Markers in Multiple Sclerosis (MS) and Experimental Autoimmune Encephalomyelitis (Eae)
We observed epitope-spreading of autoantibody responses to a variety of antigenic structures in the cerebrospinal fluid (CSF) of patients with multiple sclerosis (MS) and in the serum of mice with…
