Out of 294 patients with lung scintigrams of low or intermediate probability for pulmonary embolism, the appearances in 54 patients with a final diagnosis of pulmonary infection were reviewed. The most common finding was a matched defect in ventilation and perfusion occurring in 40 patients (76%). Regional reverse mismatch occurred in 13 patients (24%) and(More)
The purpose of this study was to determine whether intravenous or combined intravenous plus oral glucose administration was more effective inducing acute tumour acidification. Seventeen nondiabetic patients at the Henan Tumour Hospital with superficial tumour deposits of various histologies and size were administered, after fasting, either 50 g glucose(More)
OBJECTIVE To evaluate the analytical performance of the SenDx 100 portable blood gas and electrolyte analyzer (SenDx Medical, Carlsbad, CA). DESIGN Accuracy was evaluated by correlation of whole blood patient samples with the Nova Stat Profile 5 (Nova Biomedical, Waltham, MA) and the Ciba Corning 865 (Chiron Diagnostics, Medford, MA). Precision was(More)
Low levels of alpha tocopherol are related to a higher incidence of cardiovascular disease and increased intake appears to afford protection against cardiovascular disease. In addition to decreasing LDL oxidation, alpha tocopherol may exert intracellular effects on cells crucial in atherogenesis, such as monocytes. Hence, the aim of this study was to test(More)
The patterns of abnormality (both site and intensity of uptake) on bone scintigraphy in 76 total hip replacements were studied and graded to determine whether specific patterns of abnormality were associated with greater accuracy in deciding the need for revision surgery. Patients were divided into three groups: 1) 45 hips were considered to have required(More)
This paper has retrospectively analysed the ability of 99Tcm HMPAO leucocyte scintigraphy to distinguish Crohn's disease from ulcerative colitis. The diagnostic criteria were established by reviewing 99Tcm HMPAO leucocyte scintigrams in 123 patients with histologically proven Crohn's disease (83) or ulcerative colitis (40). Uptake in the right iliac fossa(More)
Chromosome 1p36.23 is frequently deleted in glioblastoma multiforme (GBM). miR-34a localizes in this region. Our experiments found that miR-34a was often deleted and epidermal growth factor receptor (EGFR) was frequently amplified in genomic DNA of 55 GBMs using single-nucleotide polymorphism DNA microarray. Notably, we found that the mean survival time was(More)
Much data support a role for both low density lipoprotein (LDL) oxidation and glycation in atherogenesis. While alpha-tocopherol decreases the oxidative susceptibility of LDL, its role in decreasing LDL glycation is unclear. Hence we tested the effect of alpha-tocopherol both in vitro and in vivo on LDL oxidation and glycation. LDL was isolated after(More)

The treatment of carcinoma of the esophagus is a challenging problem to clinicians. The 5-year survival rate of surgery reported from large centers is about 25-30%, with resectability rate around 85-90% and operation mortality rate around 5%. However, this is based on highly selected cases. The 5-year survival rate of radiation therapy is about 9-16%, while(More)
A comparative study of 99Tcm-hexamethylpropyleneamine oxime (HMPAO) and 111In leucocyte scintigraphy was performed in inflammatory bowel disease. Two hundred and thirty-four patients were studied, 146 had 99Tcm-HMPAO, 82 had 111In and six had both. The sensitivity, specificity and accuracy of the 99Tcm leucocyte scan were 96, 97 and 97%, respectively, and(More)
