Fatty liver disease can range from fatty liver alone (steatosis) to fatty liver associated with inflammation (steatohepatitis). Purpose: The study was undertaken to determine the relationships between the histological finding and biochemical measures of hepatic injury with hepatic iron content in patients with chronic liver diseases and steatosis. Methods: The study of 115 patients with chronic...
INTRODUCTION In an oral iron absorption test (OIAT), the rise in plasma iron concentration after oral ingestion of iron is a measure of intestinal iron absorption. We describe results of the OIAT using two different formulations of oral iron drops. METHODS The study included all patients who had an OIAT performed at the Department of Internal Medicine, Farsø, Aalborg University Hospital, Denm...
Abnormally high deposition of iron can contribute to neurodegenerative disorders with cognitive impairment. Since previous studies investigating cognition-brain iron accumulation relationships focused on elderly people, our aim was to explore the association between iron concentration in subcortical nuclei and two types of memory performances in a healthy young population. Gender difference was...
Iron absorption in man is inversely related to body iron stores and serum ferritin concentration. A negative correlation between intestinal iron absorption and the amount of storage iron in the body has been confirmed in the rat and the hypothesis that absorption may be regulated through the mediation of ferritin has been tested. There was no difference in mucosal iron uptake or absorption betw...
The uptake and movement of iron nanoparticles in elodea plants have been detected by the ESR method. This method is applied for the first time for the monitoring of the translocation, movement and uptake iron nanoparticles in plant organs. Exposition of stem, root or leaves of elodea in superparamagnetic iron nanoparticles (SPIONs) with concentration 12.9 mg/mL and less 10 times showed that iro...
چکیده فارسی کلی باسیلوز پرندگان توسط اشریشیاکلی بیماریزای پرندگان (apec) ایجاد می گردد. علی رغم اینکه بیش از یک قرن است که apec شناخته شده است، کلی باسیلوز پرندگان به عنوان یک بیماری مهم آندمیک که صنعت طیور دنیا را با مشکل مواجه کرده مطرح است. اشریشیا کلی بیماریزای پرندگان موجب التهاب کیسه های هوایی، سپتی سمی و عموماً دیگر بیماری های خارج روده ای در ماکیان، بوقلمون و دیگر گونه های پرندگان می ش...
BACKGROUND AND AIMS In HFE associated hereditary haemochromatosis, the duodenal enterocyte behaves as if iron deficient and previous reports have shown increased duodenal expression of divalent metal transporter 1 (DMT1) and iron regulated gene 1 (Ireg1) in affected subjects. In those studies, many patients had undergone venesection, which is a potent stimulus of iron absorption. Our study inve...
We investigated the effects of dietary iron deficiency on bone metabolism by measuring markers of bone turnover in rats. Twelve 3-week-old male Wistar-strain rats were fed a control diet or an iron-deficient diet for 4 weeks. Dietary iron deficiency decreased hemoglobin concentration and increased heart weight. Serum osteocalcin concentration, bone mineral content, bone mineral density, and mec...

BACKGROUND The current dietary iron requirement (80 mg/kg) of broilers is mainly based on growth, hemoglobin concentration, or hematocrit data obtained in a few early studies; however, expressions of iron-containing enzymes might be more sensitive novel criteria to evaluate dietary iron requirements. OBJECTIVE The objective of this study was to determine dietary iron requirements of broilers ...
