background: the aim of this study was to investigate the correlation between the cardiac and hepatic iron-overload as assessed by magnetic resonance imaging t2 star (mrit 2 -star) technique and serum ferritin level in patients with thalassemia major. methods: in this cross-sectional study we evaluated 170 patients in sayed shohada hospital in isfahan in the year of 2009, cardiac and hepatic iro...

iron overload is known to occur in the west european and american population due to the consumption of iron-rich diets. on the other hand, genetic disorders leading to iron overload are also known. iron overload leads to increased peroxidation and disruptive disintegration of lipid-rich membranes, and predisposes humans for an enhanced risk of cancer induction. in experimental animals iron over...

BACKGROUND In ventricular dilatation or hypertrophy, an elevated end-diastolic pressure is often assumed to be secondary to increased myocardial stiffness, but stiffness is rarely measured in vivo because of difficulty. We measured in vitro passive stiffness of volume- or pressure-overloaded myocardium mainly from congenital heart disease. METHODS AND RESULTS Endocardial ventricular biopsies ...

The constructor and operator overloading introduced in Modelica 3.1 is discussed. The goal is that elementary operators like “+” or “*” can be overloaded for records. This makes it possible to define and use, in a convenient way, complex numbers, polynomials, transfer functions, state space systems, etc. The chosen approach is different to other languages: (a) Only scalar operations need to be ...

There are few effective agents that safely remove excess iron from iron-overloaded individuals. Our goal was to evaluate the iron-removing effectiveness of acetaminophen given ip or orally in the gerbil iron-overload model. Male gerbils were divided into 5 groups: saline controls, iron-overloaded controls, iron-overloaded treated with ip acetaminophen, iron-overloaded treated with oral acetamin...

1. The ferritin content of iron-overloaded tissues was higher than that of normal tissues. There was also an increased iron content of ferritin extracted from these tissues. 2. In the limited number of tissues that we examined haemosiderin deposition appeared to be greater in the iron-overloaded livers than in the iron-overloaded spleens. 3. Ferritins extracted from iron-overloaded liver, splee...
