Success of meniscal repair with early or immediate motion depends on the ability of the suture fixation to withstand the loads applied. Vertical and horizontal mattress suture techniques were tested using 2-0 Ethibond, and 0-PDS and 1-PDS sutures (Ethicon, Somerville, NJ). Mulberry knot technique was tested with 0-PDS and 1-PDS sutures. Twenty menisci (60(More)
This study aims to evaluate dynamic 2-deoxy-2-[18F]fluoro-d-glucose (FDG) uptake in normal tissues. Thirty male patients underwent FDG positron emission tomography (PET)/computed tomography imaging at 1, 2, and 3 h after tracer injection. Standardized uptake values (SUV) were obtained in regions of interest of normal tissues. The aorta (blood pool), liver,(More)
Neurotrophins and their cognate receptors are critical to normal nervous system development. Trk receptors are high-affinity receptors for nerve-growth factor (trkA), brain-derived neurotrophic factor and neurotrophin-4/5 (trkB), and neurotrophin-3 (trkC). We examine the expression of these three neurotrophin tyrosine kinase receptors in the chick auditory(More)
The effect of cold exposure on the systemic renin-angiotensin system and on regulation of the angiotensin II (Ang II) receptor was examined in target organs for Ang II with cardiovascular relevance (left ventricle, kidney, lung) and metabolic relevance [interscapular brown adipose tissue (ISBAT), liver] to the functional consequences of cold exposure. In(More)
OBJECTIVE This study prospectively evaluates the serial change of FDG uptake and its diagnostic value in malignant versus benign lung lesions in patients with suspected lung cancer. PATIENTS AND METHODS Patients with suspected lung malignancy underwent whole-body FDG PET/CT at 1, 2, and 3 hours after an IV injection of F-FDG. The SUVs of FDG in lung(More)
OBJECTIVE The objectives of this article are to review the radiologic, pathologic, and clinical features of diffuse idiopathic pulmonary neuroendocrine cell hyperplasia, tumorlet, and carcinoids and to discuss the possible role of diffuse idiopathic pulmonary neuroendocrine cell hyperplasia and tumorlet in the development of carcinoids. CONCLUSION Given(More)
With the widespread application of cardiac CT has come increasing concern over the effects of radiation dose associated with this exam. Dual source CT provides a number of methods for dose reduction in helical ECG-gated cardiac CT studies. This article discusses several of these methods, with a particular emphasis on low kVp scanning, which can be applied(More)
Effective arterial elastance (E(A)) was proposed as a lumped parameter that incorporates pulsatile and resistive afterload and is increasingly being used in clinical studies. Theoretical modeling studies suggest that E(A) is minimally affected by pulsatile load, but little human data are available. We assessed the relationship between E(A) and arterial load(More)
A 69-year-old man with a lung mass underwent multiple-time-point FDG PET/CT imaging for diagnostic evaluation. The initial PET imaging (performed at 1 hour after tracer injection) revealed equivocal bone marrow uptake in the right iliac bone and proximal femurs in addition to lung and mediastinal lesions. The 3-hour delayed PET imaging, however,(More)
Primary imaging options in patients at low risk for coronary artery disease (CAD) who present with undifferentiated chest pain and without signs of ischemia are functional testing with exercise or pharmacologic stress-based electrocardiography, echocardiography, or myocardial perfusion imaging to exclude myocardial ischemia after rule-out of myocardial(More)
