Pro-inflammatory cytokines induced by inflammation and iron accumulation in the substantia nigra (SN) have been implicated in the pathogenesis of Parkinson's disease (PD). In the present study, we aimed to investigate the relationship between inflammation and iron accumulation in a lipopolysaccharide (LPS)-induced Parkinsonian rat model. The activation of glial cells and elevated levels of pro-...
Zero-valent iron is well known for the reductive dechlorination of chlorinated organics such as trichloroethylene (TCE). The activity of iron for this reaction is greatly enhanced when iron is in the form of nanoparticles. However application of these nanoparticles in fixed-bed columns, in-situ reactive barriers and in similar flow-through applications is not possible due to extremely high pres...
At the Power Systems Development Facility (PSDF), a variety of filter elements and failsafes are being tested for the cleanup of coal-generated syngas from the Kellogg Brown and Root (KBR) Transport Gasifier. Through 2007, the maximum accumulated syngas exposure for each element type was: 9,959 hours for iron aluminide sintered metal powder elements; 8,249 hours for HR-160 sintered metal fiber ...
revealed little or no hemosiderin in the tumor or bone marrow but revealed moderate to marked increases in the amount of hemosiderin in the spleen and liver of most of the chickens that were inoculated with tumor. Lymphoid tumor-bearing chickens developed a progressive hypoferremia, and there was a precipitous drop in the packed cell volume. An increase occurred in both serum iron-binding capac...
A potters clay from the Gorgan plain, in N. E. Iran, has been fired successively at temperatures up to the melting point 1 200 "C in an atmosphere of air or 5 % CO in moist COz. Mossbauer spectra at 296 K and 4.2 K allow the determination of the relative amounts of iron in well-crystallised haematite or magnetite, of poorly-crystallised and fine-particle ferric oxide or hydroxide, and of iron d...
BACKGROUND Anaemia in pregnancy is associated with adverse maternal and fetal outcome. Unfortunately, in developing countries its prevalence has continued to rise. To improve the situation, iron supplement is routinely prescribed during pregnancy. We therefore examine the impact of the intervention as being currently practised in our clinical setting. METHODS In total, 255 prenatal clinic att...
Induced Disruption of the Iron-Regulatory Hormone Hepcidin Inhibits Acute Inflammatory Hypoferraemia
Withdrawal of iron from serum (hypoferraemia) is a conserved innate immune antimicrobial strategy that can withhold this critical nutrient from invading pathogens, impairing their growth. Hepcidin (Hamp1) is the master regulator of iron and its expression is induced by inflammation. Mice lacking Hamp1 from birth rapidly accumulate iron and are susceptible to infection by blood-dwelling sideroph...
