OBJECTIVE To screen and analyze key express sequence tags (ESTs) which were differentially displayed in every period of SD rats' primary hepatic carcinoma and reveal the molecular mechanism of carcinogenesis. METHODS Using diethylnitrosamine (DENA) as a cancerigenic agent, animal models with different phases of primary hepatic cancer were constructed in SD rats. Rats were respectively sacrifi...

The asymmetric unit of the title complex, [Mn(2)(C(8)H(7)O(2))(4)(C(10)H(14)N(2)O)(2)(H(2)O)](n), contains two crystallographically independent units. In each one, the Mn(II) ions are bridged by two 4-methyl-benzoate (PMB) ligands and one water mol-ecule. In the crystal structure, each Mn(II) ion is coordinated by three PMB ligands, one water mol-ecule and two symmetry-related N,N-diethyl-nicot...

This work delineates the mechanism by which directional nanowire growth occurs in the directed electrochemical nanowire assembly (DENA) technique for growing nanowires on micro-electrode arrays. Indium, polythiophene, and polypyrrole nanowires are the subjects of this study. This technique allows the user to specify the growth path without the use of a mechanical template. Nanowire growth from ...

The title Cu(II) complex, [Cu(C(9)H(9)O(2))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], contains two 4-ethyl-benzoate (PEB) ligands, two monodentate diethyl-nicotinamide (DENA) ligands and two water mol-ecules. The four O atoms in the equatorial plane around the Cu(II) ion form a slightly distorted square-planar arrangement, while the distorted octa-hedral coordination is completed by the two N atoms of...

The number of SH-groups of the soluble proteins (Prot-SH) of 12 different types of animal tumors and of cultivated chicken fibroblasts increases with decreasing doubling time (id) ■ Between Prot-SH and id an inverse association was found with a significance level of 99.5%. After 30 min incubation in vitro, 4-hydroxypentenal (HPE) reacts with different amounts of the Prot-SH of the investigated ...

In the title complex, [Zn(C(8)H(5)O(3))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], the Zn(II) cation is located on an inversion center and is coordinated by two 4-formyl-benzoate anions, two N,N-diethyl-nicotinamide (DENA) ligands and two water mol-ecules. The four O atoms in the equatorial plane around the Zn(II) cation form a slightly distorted square-planar arrangement, while the slightly distorted ...

The title Co(II) complex, [Co(C(9)H(9)O(2))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], contains two 4-ethyl-benzoate (PEB), two monodentate diethyl-nicotinamide (DENA) ligands and two water mol-ecules. The four O atoms in the equatorial plane around the Co(II) ion form a slightly distorted square-planar arrangement, while the slightly distorted octa-hedral coordination is completed by the two N atoms o...

In the centrosymmetric mononuclear title complex, [Co(C(8)H(7)O(2))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], the Co(II) ion is located on an inversion center. The asymmetric unit contains one 4-methyl-benzoate (PMB) anion, one N,N-diethyl-nicotinamide (DENA) ligand and one coordinated water mol-ecule. The four O atoms in the equatorial plane around the Co(II) ion form a slightly distorted square-plan...

The title Cu(II) complex, [Cu(C(7)H(4)BrO(2))(2)(C(10)H(14)N(2)O)(2)(H(2)O)(2)], contains two 4-bromo-benzoate (PBB), two diethyl-nicotinamide (DENA) monodentate ligands and two water mol-ecules. The four O atoms in the equatorial plane around the Cu(II) ion form a slightly distorted square-planar arrangement, while the slightly distorted octa-hedral coordination is completed by two N atoms of ...

In the crystal of the title Cd(II) polymeric complex, [Cd(C7H4ClO2)2(C10H14N2O)(H2O)] n , the Cd(II) cation is chelated by two chloro-benzoate anions and coordinated by two N,N-di--ethyl-nicotinamide (DENA) ligands and one water mol-ecule in a distorted NO6 penta-gonal-bipyramidal geometry. The Cd(II) cations are bridged by the pyridine N atom and carbonyl O atom of the DENA ligand to form a po...
