The assumption of a dynamic coupling between regional cerebral blood flow (rCBF) and cerebral glucose metabolic rates (rCMRGlu) has been challenged by simultaneous measurements of both. Through the use of a dual-headed gamma camera with a 511-keV collimator applying the double isotope 18F-FDG and 99mTc-HMPAO SPECT technique, the uptake rates of these(More)
Single photon emission computed tomography (SPECT) and positron emission tomography (PET) are examination procedures that have shown that repetitive transcranial magnetic stimulation (rTMS) is biologically active. The aim of the present study was to investigate the patterns of regional cerebral 18F-fluorodeoxyglucose (18F-FDG) uptake and regional(More)
OBJECTIVE To review the screening program for congenital hypothyroidism in the Riyadh Al-Kharj Hospital Programme, Riyadh, Kingdom of Saudi Arabia, and to investigate the clinical and biochemical characteristics of affected infants. METHODS The study was carried out from 1985 to 2000 in the Clinical Chemistry Division, Department of Pathology, Riyadh(More)
An electronic product catalogue (EPC) is a computer controlled information system with multimedia product presentations and navigation facilities. The paper presents the results of the EPK-x project for the systematic construction of EPCs. These include a software engineering process model, a high level speciication language for EPCs, and an integrated set(More)
Reaction order in Bi-doped oxide glasses depends on the optical basicity of the glass host. Red and NIR photoluminescence (PL) bands result from Bi 2+ and Bi n clusters, respectively. Very similar centers are present in Bi-and Pb-doped oxide and chalcogenide glasses. Bi-implanted and Bi melt-doped chalcogenide glasses display new PL bands, indicating that(More)
Compared with other well established liver enzyme parameters, carbohydrate-deficient transferrin (CDT) offers a new method for the identification of chronic alcoholism. The dependence of CDT and alcoholism/abstinence was studied in 29 controls and 64 alcoholics (both groups comprising men and women). In contrast to the currently used parameters GOT, GPT,(More)

71 hydrogen plasma treatment 3.6 SUMMARY Room temperature exposure to a RF hydrogen plasma can dramatically reduce the thermal budget for the crystallization of PECVD a-Si:H films. The hydrogen plasma treatment changes the microstructure of the q-Si:Hat the surface, and depletes hydrogen from the surface of the film. The plasma treatment creates seed nuclei(More)
