BACKGROUND AND OBJECTIVES Hepcidin is a key regulator of iron homeostasis, but its study in the setting of chronic kidney disease (CKD) has been hampered by the lack of validated serum assays. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS This study reports the first measurements of bioactive serum hepcidin using a novel competitive ELISA in 48 pediatric (PCKD2-4) and 32 adult (ACKD2-4) patie...

Here we report a new, bench-top synthesis for iron/iron oxide core/shell nanoparticles via the thermal decomposition of Fe(η(5)-C(6)H(3)Me(4))(2). The iron/iron oxide core/shell nanoparticles are superparamagnetic at room temperature and show improved negative contrast in T(2)-weighted MR imaging compared to pure iron oxides nanoparticles, and have a transverse relaxivity (r(2)) of 332 mM(-1) s...

The iron-sulfur cluster compounds Fe(4)S(4)(SR)(4) (-2) [where -SR = -SCH(3), -S-C(CH(3))(3), and -S- CH(2)-CH(CH(3))(2)] have been found to represent the base species of weak acids of pK(a) comparable to that of carboxylic acids. The acid species Fe(4)S(4)(SR)(4)H(-) is most subject to reaction with O(2) and to acid-catalyzed solvolysis, while the base species Fe(4)S(4)(SR)(4) (-2) most readil...

The highly unsaturated binuclear butadiene iron carbonyls (C(4)H(6))(2)Fe(2)(CO)(n) (n = 2, 1) have been examined using density functional theory. For (C(4)H(6))(2)Fe(2)(CO)(n) (n = 2, 1), both coaxial and perpendicular structures are found. The global minima of (C(4)H(6))(2)Fe(2)(CO)(n) (n = 2, 1) are the perpendicular structures 2Q-1 and 1Q-1, respectively, with 17- and 15-electron configurat...

in order to evalutate the efficieny of green and farmyard manure and biofertilizers either separated or integrated on nitrogen dynamics in soil, leaves and grains in corn (zea mays l.), an experiment was conducted at 2009 cropping season. experiment was arranged in split split plot based on randomized complete block design with three replicates. main plots were three levels of green manure (con...

BACKGROUND Iron is essential not only for erythropoisis but also for several bioenergetics' processes in myocardium. Hepcidin is a well-known regulator of iron homeostasis. Recently, researchers identified low hepcidin was independently associated with increased 3-year mortality among systolic heart failure patients. In addition, our previous in vivo study revealed that the left ventricular mas...
