Ischemic and reperfusion injury leads to necrosis and apoptosis. Mitochondrial enzymes and antiapoptotic gene plays an important role in necrosis and apoptosis. The aim of this study was to investigate the role of Bcl-2 expression in alternations in mitochondrial energy regulation during hepatic ischemia and reperfusion and role in necrosis and apoptosis. Total 12 Wistar rats were divided into ...

The first step in splicing of pre-mRNAs with long introns is exon definition, where U1 and U2 snRNPs bind at opposite ends of an exon. After exon definition, these snRNPs must form a complex across the upstream intron to allow splicing catalysis. Exon definition and conversion of cross-exon to cross-intron spliceosomal complexes are poorly understood. Here we demonstrate that, in addition to U1...

The conformation of d(TA)3 (CG)3 has been studied in aqueous solution in the presence of high salt concentration. The oligonucleotide forms in solution concatamers. In the presence of 5 M NaC1 the concatamer is built up of d(CG)3 blocks in Z-conformation and of d(TA)3 blocks in B-conformation. In the presence of 4 M LiCl both blocks in the concatamer display a B-type structure.

[Purpose] The purpose of the present study was to investigate the effectiveness on the educational procedure development for physical therapist assistant in Quang Tri province of Vietnam. [Subjects and Methods] The subjects consisted of 10 lecturers for the education of physical therapist assistant in Quang Tri medical college. To compare with satisfaction and educational effectiveness accordin...

The use of tpy'(tpy'= 4,4',4''-tri-tert-butyl-terpyridine) as a ligand for nickel allows for the isolation of a Ni(I)-alkyl complex and a Ni(II)-alkyl halide complex, both of which can be used as mechanistic probes of key steps in alkyl cross-coupling reactions.

9-Methylacridine was identified as a generally effective ligand to promote a Pd(II)-catalyzed C(sp(3))-H and C(sp(2))-H alkylation of simple amides with various alkyl iodides. This alkylation reaction was applied to the preparation of unnatural amino acids and geometrically controlled tri- and tetrasubstituted acrylic acids.

The title compounds, K(+)·C7H7BF3O(-), (I), and K(+)·C6H4BF4 (-), (II), are mol-ecular salts containing para-substituted phenyl-tri-fluorido-borate anions. In each compound, the B atom adopts a distorted tetra-hedral BCF3 geometry. Despite their different compositions and space groups, the irregular KF8 coordination polyhedra of the potassium cations in the structures are almost identical. Thes...

The crystal structure of the dinuclear arene ruthenium title complex, [Ru2(C6H5OS)(C7H7S)2(C10H14)2]BF4, shows the two Ru(II) atoms to be bridged by two benzyl-thio-pheno-late units and one 4-hy-droxy-thio-pheno-late unit, with the remaining three coordination sites of each Ru(II) atom being occupied by p-cymene ligands, completing the typical piano-stool coordination geometry. The BF4 (-) coun...

The structures of the alkali metal (K, Rb and Cs) complex salts with 4-amino-phenyl-arsonic acid (p-arsanilic acid) manifest an isotypic series with the general formula [M2(C6H7AsNO3)2(H2O)3], with M = K {poly[di-μ3-4-amino-phenyl-arsonato-tri-μ2-aqua-dipotassium], [K2(C6H7AsNO3)2(H2O)3], (I)}, Rb {poly[di-μ3-4-amino-phenyl-arsonato-tri-μ2-aqua-dirubidium], [Rb2(C6H7AsNO3)2(H2O)3], (II)}, and C...
