In vivo 31 P MRS evaluation of ganciclovir toxicity in C6 gliomas stably expressing the herpes simplex thymidine kinase gene
(John Wiley & Sons, Ltd., 1996-12)
Phosphorus MRS was evaluated as a monitor of tumour therapeutic response to the herpes simplex virus thymidine kinase suicide gene therapy paradigm. In vivo 31 P spectra were obtained from subcutaneous rat C6 gliomas ...
Computed tomography as an adjunct to ultrasound in the diagnosis of acute acalculous cholecystitis
(Springer-Verlag; Springer-Verlag New York Inc., 1991-12)
The sonographic and computed tomographic (CT) findings were reviewed in 17 patients with acute acalculous cholecystitis (AAC) over a 6-year period from 1984 to 1989. Of the six patients in whom both ultrasound and CT were ...
CT appearance of the spleen following conservative management of traumatic injury
(Springer-Verlag; American Society of Emergency Radiology, 1999-06)
Objective: To describe the long-term changes in the traumatized spleen following conservative management in pediatric patients. Methods: Between 1991 and 1997, 92 children were imaged with splenic trauma. The study population ...
Three dimensional CT of central lung tumors
(Elsevier, 1990)
Three-dimensional computed tomography (CT) reconstructions and conventional CT were compared with surgical /pathological findings in seven patients with central lung tumors, in order to assess accuracy in predicting the ...
Metabolic loss of deuterium from isotopically labeled glucose
(Wiley Subscription Services, Inc., A Wiley Company, 1994-09)
The isotopically substituted molecule (6- 13 C, 1, 6, 6- 2 H 3 )glucose was evaluated to determine whether metabolic 2 H loss would prevent its use in quantitating pentose phosphate pathway (PPP) activity. PPP activity ...
Absolute configuration of (+)-α-dihydrotetrabenazine, an active metabolite of tetrabenazine
(Alan R. Liss, Inc.Wiley Periodiocals, Inc., 1997)
Chiral column liquid chromatography and enantiospecific enzymatic hydrolysis were utilized to separate the enantiomers of α- and Β-dihydrotetrabenazine and α-9-O-desmethyldihydrotetrabenazine, three benzo[a]quinolizines ...
Comparison of rubidium-82 positron emission tomography and thallium-201 SPECT imaging for detection of coronary artery disease
(Elsevier, 1991-06-15)
The diagnostic performance of rubidium-82 (Rb-82) positron emission tomography (PET) and thallium-201 (TI-201) single-photon emission-computed tomography (SPECT) for detecting coronary artery disease was investigated in ...
Renal obstructive dysplasia: Ultrasound diagnosis and therapeutic implications
(Springer-Verlag, 1991-05)
57 cases of renal obstructive dysplasia (defined as the abnormal development of nephronic and ductal structures due to in utero obstruction of the urinary tract) were evaluated in terms of sonographic findings, renal and ...
Evaluation of ( - )[18F]fluoroethoxybenzovesamicol as a new PET tracer of cholinergic neurons of the heart
(Elsevier, 1994-02)
18F-labeled ( - )fluoroethoxybenzovesamicol [( - )FEOBV] is a novel PET tracer which binds to the vesicular acetylcholine transporter of cholinergic neurons. To evaluate the in vivo binding specificity and kinetic properties ...
