We study a recent programming paradigm known as Adaptive Programming (AP) as an ideal candidate for a metaobject protocol (MOP) for object-oriented programming languages; we call it the AP MOP. The major beneet of the AP MOP is to provide a mechanism for writing base-level programs in a structure-shy manner. Doing so, the programs are more robust to changes in the structural aspects of the appl...

8-Methoxypsoralen (8-MOP) in ethanol, acetone, benzene, or CC14 is photo-oxidized under UV-irradiation (320-400 nm). Photo-oxidized 8-MOP (O2-8-MOP) is stable in the organic solvents, but it is destructed in water or in liposome suspension. The destruction rate constants are 0.04 s(-1) in water and 0.004 s(-1) in liposome membranes as estimated by the kinetics of the chemiluminescence accompany...

A number of studies have demonstrated that cytochrome P450 (P450) converts furanocoumarin derivatives into reactive molecules, which form covalent bonds to biomolecules. 5-Methoxypsoralen (5-MOP) is a natural furanocoumarin from apiaceous plants. In this study, we examined the effect on 5-MOP metabolism of single nucleotide polymorphisms (SNPs) in CYP2A13. We used Escherichia coli-generated rec...

The present study was designed to evaluate the effect of 8-methoxypsoralen (8-MOP) activated with visible light (419 nm) on the suppression of smooth muscle cell (SMC) proliferation in vitro. We hypothesize that if visible light (VL) instead of UVA is used to photoactivate 8-MOP, cytotoxic 8-MOP-DNA cross-link formation can be minimized. Bovine aorta SMCs (2 x 10(4)/cm2) were incubated with 8-M...

translation is an indispensable tool for communication between the diverse linguistic groups. it opens new horizons for the people living in a country so that it makes changes and improvements in their society, especially in the literature. through the translation process, some literary principles and elements are introduced into the home literature which did not exist before. these features em...

BACKGROUND Opioids are the gold standard for the treatment of acute pain despite serious side effects in the central and enteric nervous system. µ-opioid receptors (MOPs) are expressed and functional at the terminals of sensory axons, when activated by exogenous or endogenous ligands. However, the presence and function of MOP along nociceptive axons remains controversial particularly in naïve a...

The Ti plasmid in Agrobacterium tumefaciens strain 15955 carries two alleles of traR that regulate conjugative transfer. The first is a functional allele, called traR, that is transcriptionally induced by the opine octopine. The second, trlR, is a nonfunctional, dominant-negative mutant located in an operon that is inducible by the opine mannopine (MOP). Based on these findings, we predicted th...

BACKGROUND Alcoholism is a widespread chronic disorder of complex aetiology with a significant negative impact on the individual and the society. Mechanisms of ethanol action are not sufficiently well understood at the molecular level and the pharmacotherapy of alcoholism is still in its infancy. Our study focuses at the cellular and molecular level on ethanol-induced effects that are mediated ...

BACKGROUND (-)-Pentazocine has been hypothesized to induce analgesia via the κ-opioid (KOP) receptor, although the involvement of other opioid receptor subtypes in the effects of pentazocine remains unknown. In this study, we investigated the role of the μ-opioid (MOP) receptor in thermal, mechanical, and chemical antinociception induced by (-)-pentazocine using MOP receptor knockout (MOP-KO) m...

BACKGROUND It has been shown that cytochrome P450 enzymes (CYPs) and acetyltransferase can be used as biomarkers of carcinogen-DNA adduct levels and human cancer susceptibility. The gastrointestinal tract is the portal of entry of foreign compounds and presents xenobiotic metabolizing N-acetyltransferase (NAT) and CYPs activities. 5-Methoxypsoralen (5-MOP) has been used in combination with UV r...
