It is now increasingly appreciated that glial cells play a critical role in the regulation of iron homeostasis. Impairment of these properties might lead to dysfunction of iron metabolism and neurodegeneration of neurons. We have previously shown that dysfunction of glia could cause iron deposit and enhance iron-induced degeneration of dopamine (DA) neurons in Parkinson's disease (PD). There al...

Different types of iron oxides deposits have been identified along the Khaf – Dorouneh volcanic and plutonic belt in north east of Iran. Kuh-e-Zar is one of these ore deposits known as Fe- oxide gold deposit. The main purpose of this paper is to detect and discriminate the iron oxide minerals in this area based on the ETM+ data. Data processing has been done by ENVI (Environment for Visualizing...

Iron ore deposit Bijar area is located in east north in Kordestan province based of field observation, ore minerals are magnetite, magnetite-martitite and magnetite-pyrite. No. 922 points on the 16 profiles were collected over about 7500 meters in the area. Magnetometers treatment of advanced devices and new GSM-19T is made in Canada. The data were corrected and the magnetic field intensity map...

   The Asinawa iron ore is located about 3km to the southeast of Penjween town, Sulaimaniya Governorate, Kurdistan Region, Northeastern Iraq near the Iraq-Iran border. The exposed iron ore deposit is about 60 and 400m wide and long respectively. The present study is the re-study of the geology and geochemistry of the Asnawan Iron ore deposit  and concluded that the country rocks are consist of ...

estimation of the metal value in the metallic deposits is one of the important factors to evaluate the deposits in exploration studies andmineral processing. therefore, one accurate estimator is essential to obtain a fine insight into the accumulation of the ore body. thereare geostatistical methods for the estimation of the concentration of iron which performance of these models is complexity ...

Rats fed a corn grit diet containing large amounts of ferric citrate absorb and deposit excessive amounts of iron in their livers. Undoubtedly various factors are involved in iron absorption, but these studies indicate that the low level of dietary phosphate was primarily responsible. The addition of phosphate salts to this diet has shown that the amount of iron deposited in the liver was inver...
