UNLABELLED Although pituitary adenomas are regarded as benign tumors, some of them behave aggressively with malignant behavior of invasion and metastasis. Prediction of such biologic behavior in a tumor is important for therapeutic planning. The purpose of this study was to assess the usefulness of 201Tl chloride SPECT (201Tl SPECT) for evaluation of biologic behavior in pituitary adenomas. M...

UNLABELLED In patients with pulmonary hypertension (PH) the right ventricular (RV)-to-left ventricular (LV) ratio of fatty acid uptake is reduced. In animal studies, such a finding was combined with an increased glucose uptake in RV myocardium. The aim of this study was to measure the metabolic rates of glucose uptake for the RV and LV myocardium in patients in relationship to parameters of RV ...

UNLABELLED Renal function is known to be a strong predictor of cardiovascular prognosis, and cardiorenal disease is increasingly investigated in medical research. In this study, we tested the hypothesis that a single combined cardiorenal scintigraphy examination with the perfusion tracer (99m)Tc-tetrofosmin is feasible and may allow the simultaneous investigation of cardiac and renal pathology ...

BACKGROUND Increased levels of inflammation markers, such as C-reactive protein (CRP) and tumor necrosis factor-alpha , have been found in insulin resistance syndrome. Those with elevated levels of high-sensitive CRP (hs-CRP) are at a higher risk for coronary heart disease. In the present study, we evaluated whether maximum oxygen uptake and insulin resistance are related to hs-CRP for the prim...

BACKGROUND AND OBJECTIVES Insulin has several physiologic actions that include stimulation of cellular glucose and potassium uptake. The ability of insulin to induce glucose uptake by cells is impaired in type 2 diabetes mellitus, but whether potassium uptake is similarly impaired is not known. This study examines whether the cellular uptake of these molecules is regulated in concert or indepen...

Both tendon and peritendinous tissue show evidence of metabolic activity, but the effect of acute exercise on substrate turnover is unknown. We therefore examined the influence of acute exercise on glucose uptake in the patellar and quadriceps tendons during dynamic exercise in humans. Glucose uptake was measured in five healthy men in the patellar and quadriceps tendons and the quadriceps femo...

OBJECTIVE The aim was to evaluate the proliferative activity of high-uptake areas on positron emission tomography (PET) with the hypoxic cell radiotracer, 1-(2-[(18)F]fluoro-1-[hydroxymethyl]ethoxy)methyl-2-nitroimidazole (FRP170). METHODS Thirteen patients with glioblastoma underwent FRP170 PET before tumor resection. During surgery, tumor specimens were stereotaxically obtained from regions...
