We reported a case of a 72-year-old male, known diabetic on insulin, referred because of complete atrioventricular block. He was found to have acute hepatitis during which he developed transient atrial arrhythmia, and sinus node dysfunction. His cardiac symptoms disappeared completely after hepatitis improvement. All of his cardiac investigations were normal including electrocardiogram, echocar...
A small scale sample nuclear waste package, consisting of a 28mm diameter uranium penny encased in grout, was imaged by absorption contrast radiography using a single pulse exposure from an X-ray source driven by a high-power laser. The Vulcan laser was used to deliver a focused pulse of photons to a tantalum foil, in order to generate a bright burst of highly penetrating X-rays (with energy >5...
introduction: poor sensitivity and poor signal to noise ratio because of low injected thallium dose and presence of scattered photons are the main problems in using thallium in scintigraphic imaging of the heart. scattered photons are the main cause of degrading the contrast and resolution in spect imaging that result in error in quantification. thallium decay is very complicated and photons ar...
Thirty one patients with biologic and clinical diagnosis of hyperparathyroidism were submitted to thalium-technetium scan prior to exploration of the neck. Scan findings were compared with the pathologic results. Surgical exploration of the neck showed a parathyroid adenoma in 24 patients, parathyroid carcinoma in one patient, normal parathyroid in another patient and parathyroid hyperplasia in...
Anaphylactic shock, as a kind of distributive shock, is considered as a consequence of histamine induced vasodilatation with increased vascular permeability. Tachycardia is the early warning sign of shock and bradycardia is a rare manifestation of shock. A 78 year-old woman presented with shrimpinduced anaphylactic shock with bradycardia. She was treated by beta-blocker currently and further Th...
We study periodic lattices, such as vortex lattices in type II superconductors in a random pinning potential. For the static case we review the prediction [1,2] that the phase diagram of such systems consists of a topologically ordered Bragg glass phase, with quasi long range translational order, at low fields. This Bragg glass phase undergoes a transition at higher fields into another glassy p...
