a novel ternary schiff base ligand (hl) of ono type and its copper (ii) complex weresynthesised using 2-aminophenol and o-acetoacetotoluidide. they have been characterised by theusual analytical and spectral methods. the interaction of the complex with calf-thymus (ct)dna has been investigated by uv-vis, viscosity measurement, cyclic voltammetry anddifferential pulse voltammetry studies. the re...

PARP-1 is a nuclear enzyme regulating transcription, chromatin restructuring, and DNA repair. PARP-1 is activated by interaction with NAD+, DNA, and core histones. Each route of PARP-1 activation leads to somewhat different outcomes. PARP-1 interactions with core histones control PARP-1 functions during transcriptional activation in euchromatin. DNA-dependent regulation of PARP-1 determines its...

In this lecture, we study several types of auctions, and we introduce the Envelope Theorem (E.T.) to analyze the payoffs for the auctions. The expected payoff in each case is found to be the expectation of the second highest valuation. The VickreyClarke-Grove (VCG) allocation mechanism is used in a generalized scenario of the auctions, and it produces a dominant strategy with the resulting Nash...

The binding interaction of novel podophyllotoxin derivative, (3R,4R)-4-((benzo[d][1,3]dioxol-5-yl)methyl)-dihydro-3-(hydroxy(3,4-dimethoxyphenyl) methyl) furan-2(3H)-one (PPT), with calf thymus DNA (ctDNA) has been examined using UV-Visible absorption spectrophotometry, fluorescence spectroscopy, viscosity measurement and molecular docking studies. UV-Vis absorption results showed hyperchromic ...

Ten years after the event and the question as to exactly why a driver passed a signal at danger to cause the Ladbroke Grove rail disaster is still an open one. This paper uses the literature on human error and cognition, combined with critical path analysis, to provide further insight. Five aspects of train operation are drawn out of the known facts surrounding the incident: custom and practice...

In this study, we were synthesized Fe3O4@LDH@Lamivudine and characterized by FT-IR spectroscopy,XRD and TEM. The interaction of this nanoparticle with CT-DNA was investigated by viscosity, circulardichroism (CD), Uv-Visible and fluorescence spectroscopy. Among all nanocarriers which applied as drugdelivery vectors, layered double hydroxides (LDHs) with exchangeable anions in t...

Positively charged endogenous and exogenous organic compounds of diverse chemical structures are transported by polyspecific organic cation transporters (OCT). In two contributions to the May 2005 issue of Molecular Pharmacology, amino acid residues within the fourth and tenth transmembrane helices of rat OCT1 are described that contribute to cation and corticosterone binding. In a three-dimens...
