Three experiments wereconducted to evaluate chemical characteristics, intestinal absorption and bioavailability of manganese(Mn)from organic, inorganic and nano sources of Mn. In experiment 1, inorganic sources of Mn including Mn-sulphate and Mn-oxide, organic sources of Mn as Mn-glycinate and Mn-bioplex and FRA® easy dry Mn as a nano source of Mn were subjected to elemental analysis and solubi...
The reactions of the Mn(III)(3) and Mn(II)Mn(III)(2) complexes [Mn(3)O(O(2)CEt)(6)(py)(3)][ClO(4)] and [Mn(3)O(O(2)CEt)(6)(py)(3)] with pyridine-2,6-dimethanol (pdmH(2)) afford the mixed-valence Mn(II)(6)Mn(III)(2) octanuclear complex [Mn(8)O(2)(py)(4)(O(2)CEt)(8)(L)(2)][ClO(4)](2) (1) and the Mn(II)(7)Mn(III)(2) enneanuclear complex [Mn(9)(O(2)CEt)(12)(pdm)(pdmH)(2)(L)(2)] (2), respectively. B...
The complexes of Mn(OAc)3 and/or Mn(acac)3 with nucleic bases and nucleosides (adenine, guanine, xanthine, adenosine and guanosine) have been synthesized in nonaqueous solution. Polarographic and spectroscopic (IR and Visible) methods have been used to establish the active site(s) on the imidazole and pyrimidine rings in the nucleic bases and nucleosides for the intera...

An extensive number of pathologies are associated with mitochondrial dysfunction (MDF) and oxidative stress (OS). Thus, mitochondrial cofactors termed "mitochondrial nutrients" (MN), such as α-lipoic acid (ALA), Coenzyme Q10 (CoQ10), and l-carnitine (CARN) (or its derivatives) have been tested in a number of clinical trials, and this review is focused on the use of MN-based clinical trials. The...
determination of uranium in natural water and complex solutions using ion exchange chromatography: a combined procedure using ion exchange chromatography and uv-vis spectrophotometry techniques has been developed to measure uranum in natural water and complex solutions. after conditicing , one hundred milli liters of sample solutions have been passed through an ion exchange column,pachked with ...
In the title coordination polymer, {[FeMn(C(5)H(5))(C(13)H(7)O(4))(C(10)H(9)N(3))(H(2)O)]·CH(3)OH·H(2)O}(n), the Mn(II) ion has a distorted octa-hedral coordination geometry and is ligated by two N atoms from two di-2-pyridyl-amine mol-ecules, three O atoms from two 5-ferrocenyl-benzene-1,3-dicarboxyl-ate anions and one O atom from a coordinated water mol-ecule. The Mn-O distances range from 2....
