We report the measurement of D-beta-hydroxybutyrate (BHB) in the brains of six normal adult subjects during acute infusions of BHB. We used high field in vivo (1)H magnetic resonance (MR) spectroscopy in the occipital lobe in conjunction with an acut

One-dimensional spectroscopic imaging of (13)C-4-glutamate turnover is performed in the human brain with a 6 cc nominal voxel resolution at 4T. Data were acquired with an indirect detection approach using a short spin echo single quantum (1)H-(13)C h

To investigate the use of proton spectroscopy to measure abdominal fat content in pre-obese offspring of obese and lean Zucker diabetic fatty (ZDF-drt) rats.Large and small litters (size 4-15, 127 pups total) were serially measured during the sucklin

The familial occurrence of achalasia has been previously recorded and a genetic origin for the disease has been postulated. We present the first case of achalasia in monozygotic twins and suggest that concordance for the disease is consistent with a

A sealed‐off rf‐excited CO2 waveguide laser was used to investigate the relative performance with C13O2 and C12O2 mixtures. By modulating the laser at various rates and pulse widths, we demonstrated effects due to both temperature and upper level

Reactive Q switching of a CO2 laser by means of a piezoelectrically actuated end reflector is reported. The high‐frequency response of the piezoelectric transducer was maintained by optically polishing the transducer’s surface directly instead of

A prospective blinded study comparing the indium 111 leukocyte scan to barium enema, colonoscopy, or surgery or a combination of these, was carried out in 15 patients (10 with active ulcerative colitis and 5 with active Crohn's colitis). Correlation

Substitution of He3 for normal helium in a sealed‐off conventional CO2 laser resulted in power output increases as high as 14%. No such effect was observed in a narrow‐bore waveguide laser, indicating that the observed improvements were due to mo
