چکیده : بیماری های قلبی هر ساله نزدیک به 40 درصد از مرگومیرها را در جهان به خود اختصاص می دهند. بالا بودن چربی های خون، کم تحرکی، پرفشارخونی، مصرف دخانیات و دیابت از عوامل خطرزای سنتی و شاخص های التهابی، هموسیستئین و مقاومت انسولینی نیز از عوامل خطرزای جدید بیماری قلبی عروقی می باشند که طبق بررسی های مختلف میزان آن ها در زنان یائسه بالا می رود. در واقع بیماری قلبی عروقی از جمله بیماری ها...
(99m)Tc-Tetrofosmin ((99m)Tc-TF) and (99m)Tc-Sestamibi ((99m)Tc-MIBI) are SPECT tracers that have been used for brain tumor imaging. Tumor's multidrug resistance phenotype, namely, P-glycoprotein (p-gp), and the multidrug resistance related proteins (MRPs) expression have been suggested to influence both tracers' uptake. In the present study we set out to compare (99m)Tc-TF and (99m)Tc-MIBI upt...
We analyze the magnitude of the specific heat jump ∆C at the superconducting transition temperature Tc in the situation when superconductivity develops in the pre-existing antiferromagnetic phase. We show that ∆C/Tc differs from the BCS value and is peaked at the tri-critical point where this coexistence phase first emerges. Deeper in the magnetic phase, the onset of coexistence, Tc, drops and ...
Two propylene amine oxime (PnAO) complexes, 1, containing a 3-nitro-1,2,4-triazole and 2, containing two 3-nitro-1,2,4-triazoles, were synthesized and radiolabeled with (99m)Tc in high labeling yields. Cellular uptakes of (99m)Tc-1 and (99m)Tc-2 were tested using a S180 cells line. Under anoxic conditions, the cellular uptakes of (99m)Tc-1 and (99m)Tc-2 were 33.7 ± 0.2% and 35.0 ± 0.7% at 4 h, ...
OBJECTIVES QT interval prolongation is prevalent among patients with Takotsubo cardiomyopathy (TC), whereas torsades de pointes (TdP) has rarely been reported in these patients. We studied all peer-reviewed reports on TC-associated QT interval prolongation and all peer-reviewed reports on TC-associated TdP to characterize the clinical circumstances leading to TdP in patients with TC. METHODS ...
Objectives. Studies comparing outcome of single-(99m)Tc-methoxyisobutylisonitrile ((99m)Tc-sestamibi) and dual-tracer (99m)Tc-sestamibi scintigraphy in combination with (123)I before primary surgery of primary hyperparathyroidism (PHPT) are scarce. Methods. We compared (99m)Tc-sestamibi/(123)I and (99m)Tc-sestamibi in a single-centre retrospective series of 269 PHPT patients. The results were r...
Tropical cyclone (TC) size, usually measured with the radius of gale force wind (34 kt or 17m s), is an important parameter for estimating TC risks such as wind damage, rainfall distribution, and storm surge. Previous studies have reported that there is a very weak relationship between TC size and TC intensity. A close examination presented here using satellite-based wind analyses suggests that...
