The crystal structure and the magnetic properties of a heterodinuclear complex, [LCu(Me2CO)Gd(NO3)3]2 (L=N,N’-bis(2-hydroxy-3-methoxybenzylidene)-1,3-diaminopropane) are reported: [(C19H20N2O4)Cu(C3H6O)Gd(NO3)3]2, triclinic, space group P1, with a = 12.118.3(9), b = 13.562(3), c = 9.391(3) Å, α = 93.03(3), β = 107.65(2), γ = 73.07(2)◦ , V = 1406.0(7) Å3, Z = 1. The crystal structure consists of...
Meiosis in mammalian oocytes includes two asymmetric meiotic divisions that result in extrusion of the first and second polar bodies (PBI and PBII, respectively). Fyn, an Src family kinase (SFK), colocalizes with filamentous actin (F-actin) at the meiotic cleavage furrow area of mouse oocytes. In this paper, these studies are extended to rat oocytes. Furthermore, inhibition of Fyn decreased the...
The strong LAC4 promoter (P(LAC4)) from Kluyveromyces lactis has been extensively used to drive expression of heterologous proteins in this industrially important yeast. A drawback of this expression method is the serendipitous ability of P(LAC4) to promote gene expression in Escherichia coli. This can interfere with the process of assembling expression constructs in E. coli cells prior to thei...
کمپلکسهای حاصل از لیگاندهای خانواده پیرازولیل وپلی پیرازولیل بورات با فلزات مختلف مثل نقره(i)، مس(i)ومس(ii) خواص و کاربردهای متنوع و مهمی دارند که از آن جمله می توان به خاصیت ضد میکروبی بالای کمپلکسهای پلی پیرازولیل بورات نقره(i) و استفاده از آن در صنایع دارویی و همچنین کمپلکسهای مشابه مس(i)ومس(ii) و کاربردهای فراوان آنها در حوزه های بیوشیمی ، ضدقارچها، آنتی تومورها و کاتالیست ها اشاره کرد . در...
in this thesis, phosphorus ylides [phbppy], [no2bppy] and [brbppy] have been synthesized through the formation of phosphonium salt and dihydrogenation, followed by the reaction of pd(oac)2 and the orthopalladated dinuclear complexes [pd(?-cl)(phbppy)]2, [pd(?-cl)(no2bppy)]2 and [pd(?-cl)(brbppy)]2 have been produced. the reaction of dinuclear complexes and bidentate ligands [l = bipy (2,2-bipyr...
Coconut water (Cocos Nucifera) is shown to be a source of essential elements present in the form low-molecular weight stable complexes known for their bio-availability. The total element concentrations were range 0.2–2.7, 0.3–1, 3–14 and 0.5–2 ppm Fe, Cu, Mn, Zn, respectively, varied as function origin nut its maturity. Speciation was investigated by size-exclusion chromatography - inductively ...
This report describes the dimerisation of glutathione, and by extension, other cysteine-containing peptides or protein fragments, with a 5, 5'-disubstituted-2, 2'-bipyridine or 6, 6"-disubstituted-2, 2':6',2"-terpyridine unit. The resulting bipy-GS2 and terpy-GS2 were investigated as potential metal ion dependent switches in aqueous solution, and were found to predominantly adopt the transoïd c...
Sr2Cu3O4Cl2 has CuI and CuII subsystems, forming interpenetrating S=1/2 square lattice Heisenberg antiferromagnets. The classical ground state is degenerate, due to frustration of the intersubsystem interactions. Magnetic neutron scattering experiments show that quantum fluctuations cause a two dimensional Ising ordering of the CuII's, lifting the degeneracy, and a dramatic increase of the CuI ...
