Inherited mitochondrial respiratory chain disorders are progressive, life-threatening conditions for which there are limited supportive treatment options and no approved drugs. Because of this unmet medical need, as well as the implication of mitochondrial dysfunction as a contributor to more common age-related and neurodegenerative disorders, mitochondrial(More)
Twenty-two depressed adults were scanned with perfusion single-photon computed emission tomography before and after 2 weeks of left perfrontal transcranial magnetic stimulation (TMS) in a parallel design, double-blind treatment study. At medication-free baseline, across all subjects, blood flow in the bilateral medial temporal lobes, left prefrontal cortex,(More)
Relative regional brain blood flow was measured in 23 clinically depressed adults by using ECD SPECT at baseline and again during actual prefrontal transcranial magnetic stimulation (TMS) following 5 daily sessions of TMS. TMS over prefrontal cortex caused increased activity in cortex directly under the stimulation (inversely correlated with distance from(More)
BACKGROUND The Japanese Ministry of Health and Welfare guidelines (JMHWG) are currently the standard used to diagnose cardiac sarcoidosis. JMHWG incorporate (67)Gallium scintigraphy as a minor criterion, while fasting (18)fluorine-2-fluoro-2-deoxy-D-glucose (FDG) PET is not included. As there is no published data comparing the accuracy of prolonged fasting(More)
While decreased ATP production and redox imbalance are central to mitochondrial disease pathogenesis, efforts to develop effective treatments have been hampered by the lack of imaging markers of oxidative stress. In this study we wished to determine if Tc99m-HMPAO, a SPECT imaging marker of cerebral blood flow and glutathione/protein thiol content, could be(More)
Visual cortical surface area varies two- to threefold between human individuals, is highly heritable, and has been correlated with visual acuity and visual perception. However, it is still largely unknown what specific genetic and environmental factors contribute to normal variation in the area of visual cortex. To identify SNPs associated with the(More)
The incidence of osteoporosis and fractures of the hip are diminished in blacks and in obese subjects. To determine whether bone mass is increased in them, bone mineral density (BMD) of the lumbar spine, trochanter, and femoral neck was measured by dual photon absorptiometry in 89 nonobese white and 51 nonobese black women, all of whom were within 30% of(More)
Following spinal cord injury in rats there was a time-dependent change of vascular permeability as reflected by extravasation of 125I-labelled serum albumin. The change of vascular permeability correlated with tissue calcium and water accumulation suggesting that cord exposure to plasma calcium as a consequence of vascular injury may contribute to the(More)
Because leukotrienes and prostaglandins are inflammatory mediators derived from arachidonic acid, their potential role in oleic acid-induced lung injury was evaluated in control and in essential fatty acid-deficient (EFAD) rats depleted of arachidonic acid substrate. In control rats, oleic acid (0.06 ml/kg iv) increased the pulmonary permeability index(More)
PURPOSE To determine the diagnostic performance of In-111 capromab pendetide single photon emission computed tomography/computed tomography (SPECT/CT), in the prostate gland, seminal vesicles, and lymph nodes via correlation to a gold standard of histopathology. MATERIALS AND METHODS In this study, we retrospectively reviewed all In-111 capromab pendetide(More)
