Asymmetric dimethylarginine is not a good predictor of ischemia using myocardial perfusion scintigraphy.

Background/aim: Asymmetric dimethylarginine (ADMA) plays role in the pathogenesis of coronary artery disease and related mortality and morbidity through a number of mechanisms. We hypothesized that plasma ADMA levels would be increased in the presence of reversible ischemia as measured by GATED single photon emission computed tomography (SPECT) myocardial perfusion scintigraphy (MPS).

Materials And Methods: Fasting i.

Resistin predicts ischemia in myocardial perfusion scintigraphy.

Unlabelled: Aim: Resistin plays a role in the pathogenesis of coronary artery disease and is related to mortality and morbidity through a number of mechanisms. We hypothesize that plasma resistin levels are increased in the presence of ischemia, as measured by GATED single- photon emission computed tomography myocardial perfusion scintigraphy (SPECT MPS), in comparison with nonischemic subjects.

Materials And Methods: Fasting intravenous blood samples of patients were drawn before a stress test.

The Scintigraphic Findings of Gastroesophageal Reflux in Children is Related to Body Weight?

Background: Gastroesophageal reflux disease (GERD) is the most common cause of children admissions to pediatric gastroenterology unit and affects about 30% of pediatric population. Body weight and height percentiles of children with GERD and their relationship between presence and the severity of reflux on scintigraphic images were studied.

Methods: Patients who underwent reflux scintigraphy between 2005 - 2012 were retrospectively reviewed.

Does PRRT with standard activities of 177Lu-octreotate really achieve relevant somatostatin receptor saturation in target tumor lesions?: insights from intra-therapeutic receptor imaging in patients with metastatic gastroenteropancreatic neuroendocrine tumors.

Background: Peptide receptor radionuclide therapy (PRRT) with 177Lu-[DOTA0,Tyr3]octreotate (177Lu-octreotate) is generally performed using a fixed activity of 7.4 GBq (200 mCi) per course bound to 180 to 300 μg of the peptide. While this single activity may lead to suboptimal radiation doses in neuroendocrine tumors (NET) with advanced or bulky disease, dose escalation has been withheld due to concerns on potential tumor somatostatin receptor saturation with reduced efficacy of the added activity.

Efficiency of radioactive I-131 therapy in geriatric patients with toxic nodular goiter.

Background And Aims: The success of I-131 therapy in geriatric patients who were referred to an endocrinology clinic with toxic nodular goiter and who lived in iodine-deficiency regions was studied.

Materials And Methods: Patients older than 60 years who received I-131 therapy were included via retrospective data analyses. Fifty-nine patients between 60 and 82 years of age were enrolled in the study.

Correlation of the vesicular acetylcholine transporter densities in the striata to the clinical abilities of women with Rett syndrome.

Rett syndrome (RTT) is a neurodevelopmental disability characterized by mutations in the X-linked methyl-CpG-binding protein 2 located at the Xq28 region. The severity is modified in part by X chromosomal inactivation resulting in wide clinical variability. We hypothesized that the ability to perform the activities of daily living (ADL) is correlated with the density of vesicular acetylcholine transporters in the striata of women with RTT.
