Positron emission tomographic imaging of cardiac sympathetic innervation and function.
Sites of uptake, storage, and metabolism of [18F]fluorodopamine and excretion of [18F]fluorodopamine and its metabolites were visualized using positron emission tomographic (PET) scanning after intravenous injection of the tracer into anesthetized dogs. Radioactivity was concentrated in the renal pelvis, heart, liver, spleen, salivary glands, and gall bladder. Uptake of 18F by the heart resulte...

پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
15 صفحه اولImprovement of cardiac sympathetic innervation by renal transplantation.
UNLABELLED Chronic renal failure (CRF) patients on dialysis frequently show reduced heart rate variability (HRV), which has been reported to be corrected by renal transplantation. Recently, (123)I-metaiodobenzylguanidine ((123)I-MIBG) scintigraphy has been used to evaluate cardiac sympathetic innervation, and uremic patients often show marked abnormalities of cardiac (123)I-MIBG uptake. We inve...
متن کاملMetaiodobenzylguanidine scintigraphy of cardiac sympathetic innervation.
Metaiodobenzylguanidine (MIBG), a noradrenaline analogue,labelled with radioactive iodine I-123 is used for assessing pre-synaptic activity of the myocardial adrenergic system. The paper describes the mechanism of myocardial I-123-MIBG uptake and the relevant examination methods. It also refers to the necessity of standardising acquisition methods and assessment criteria in order to improve com...
متن کاملIn situ three-dimensional reconstruction of mouse heart sympathetic innervation by two-photon excitation fluorescence imaging.
BACKGROUND Sympathetic nerve wiring in the mammalian heart has remained largely unexplored. Resolving the wiring diagram of the cardiac sympathetic network would help establish the structural underpinnings of neurocardiac coupling. NEW METHOD We used two-photon excitation fluorescence microscopy, combined with a computer-assisted 3-D tracking algorithm, to map the local sympathetic circuits i...
