Excited‐State Properties and Environmental Effects for Protonated Schiff Bases: A Theoretical Study
Authors: Aquino Adélia J. A. , Barbatti Mario , Lischka Hans 
Published: August 2006

AbstractComplete active space self‐consistent field (CASSCF), multireference configuration interaction (MRCI), density functional theory (DFT), time dependent DFT (TDDFT) and the singles and doubles coupled‐cluster (CC2) methodologies have been used to study the ground state and excited states of protonated and neutral Schiff bases (PSB and SB) as models for the retinal chromophore. Systems with two to four conjugated double bonds are investigated. Geometry relaxation effects are studied in the excited ππ* state using the aforementioned methods. Taking the MRCI results as reference we find that CASSCF results are quite reliable even though overshooting of geometry changes is observed. TDDFT does not reproduce bond alternation well in the ππ* state. CC2 takes an intermediate position. Environmental effects due to solvent or protein surroundings have been studied in the excited states of the PSBs and SBs using a water molecule and solvated formate as model cases. Particular emphasis is given to the proton transfer process from the PSB to its solvent partner in the excited state. It is found that its feasibility is significantly enhanced in the excited state as compared to the ground state, which means that a proton transfer could be initiated already at an early step in the photodynamics of PSBs.
Optical Properties of Lanthanide‐Doped Lamellar Nanohybrids
Authors: Sá Ferreira Rute A. , Karmaoui Mohamed , Nobre Sónia S. , Carlos Luís D. , Pinna Nicola 
Published: August 2006

AbstractIn this article a detailed study of the optical properties of lanthanide doped lamellar nanohybrids synthesized by the “benzyl alcohol route” is presented. The synthetic approach results in the formation of a highly ordered lamellar nanocomposite consisting of yttrium or gadolinium oxide crystalline layers with a confined thickness of about 0.6 nm, separated from each other by organic layers of intercalated benzoate molecules. When the inorganic layers are doped with optically‐active lanthanide ions they show outstanding emission properties in the green (Tb3+), red (Eu3+) and near infrared (Nd3+). The local environment of the emitting ions and the energy transfer processes involving the phenyl ring of the benzoate complexes and the lanthanide ions are presented, as well as radiance and lifetime measurements. The radiance values are comparable and in some cases even larger than those of standard phosphors, proving that these nanohybrids can compete, from an emission efficiency point of view, with commercial phosphors. Furthermore, in these nanohybrids it is possible by simply changing the excitation wavelength, to tune the emission colour chromaticity without loosing the radiance.
A wavelet‐based piecewise approach for steady‐state analysis of power electronics circuits
Authors: Tam K. C. , Wong S. C. , Tse C. K. 
Published: August 2006

AbstractSimulation of steady‐state waveforms is important to the design of power electronics circuits, as it reveals the maximum voltage and current stresses being imposed upon specific devices and components. This paper proposes an improved approach to finding steady‐state waveforms of power electronics circuits based on wavelet approximation. The proposed method exploits the time‐domain piecewise property of power electronics circuits in order to improve the accuracy and computational efficiency. Instead of applying one wavelet approximation to the whole period, several wavelet approximations are applied in a piecewise manner to fit the entire waveform. This wavelet‐based piecewise approximation approach can provide very accurate and efficient solution, with much less number of wavelet terms, for approximating steady‐state waveforms of power electronics circuits.

Published: August 2006

AbstractThe existence of oxaarsetanes during an arsa‐Wittig reaction has been proved by 1H and 17O NMR spectroscopy. 75As NMR spectra were obtained from the corresponding arsonium salts and arsane oxides. The dynamic 1H NMR spectra of phospha‐ and arsaylides were compared. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
DNA damage and mutagenicity induced by endosulfan and its metabolites
Authors: Bajpayee Mahima , Pandey Alok Kumar , Zaidi Sabina , Musarrat Javed , Parmar Devendra , Mathur Neeraj , Seth Prahlad Kishore , Dhawan Alok 
Published: August 2006

AbstractEndosulfan is a widely used broad‐spectrum organochlorine pesticide, which acts as a contact and stomach poison. Nontarget species, such as cattle, fish, birds, and even humans, are also affected. Studies on the genotoxicity and mutagenicity of endosulfan have been inconsistent and nothing is known about the genotoxicity of its metabolites. In the present study, endosulfan (as a commercial isomeric mixture and as the α‐ and β‐isomers), and metabolites of endosulfan (the sulfate, lactone, ether, hydroxyether, and diol derivatives) were assayed for their ability to induce DNA damage in Chinese hamster ovary (CHO) cells and human lymphocytes using the Comet assay and were assayed for their mutagenicity using the Salmonella reversion assay (Ames test with TA98, TA97a, TA102, TA104, and TA100, with and without S9 activation). The compounds produced statistically significant (P < 0.01), concentration‐dependent (0.25–10 μM) increases in DNA damage in both CHO cells and human lymphocytes. Endosulfan lactone caused the most DNA damage in CHO cells, while the isomeric mixture of endosulfan produced the greatest response in lymphocytes. The test compounds also were mutagenic in Salmonella strains at concentrations of 1–20 μg/plate (P < 0.05), with TA98 being the most sensitive strain and the diol and hydroxyether metabolites producing the highest responses. The results indicate that exposure to sublethal doses of endosulfan and its metabolites induces DNA damage and mutation. The contribution of the metabolites to the genotoxicity of the parent compound in Salmonella and mammalian cells, however, is unclear, and the pathways leading to bacterial mutation and mammalian cell DNA damage appear to differ.

True health vs response styles: exploring cross‐country differences in self‐reported health
Authors: Jürges Hendrik 
Published: August 2006

AbstractThe aim of this paper is to decompose cross‐national differences in self‐reported general health into parts explained by differences in ‘true’ health, measured by diagnosed conditions and measurements, and parts explained by cross‐cultural differences in response styles. The data used were drawn from the Survey of Health, Ageing and Retirement in Europe 2004 (SHARE), using information from 22 731 individuals aged 50 and over from 10 European countries. Self‐rated general health shows large cross‐country variations. According to their self‐reports, the healthiest respondents live in the Scandinavian countries and the least healthy live in Southern Europe. Counterfactual self‐reported health distributions that assume identical response styles in each country show much less variation in self‐reports than factual self‐reports. Danish and Swedish respondents tend to largely over‐rate their health (relative to the average) whereas Germans tend to under‐rate their health. If differences in reporting styles are taken into account, cross‐country variations in general health are reduced but not eliminated. Failing to account for differences in reporting styles may yield misleading results. Copyright © 2006 John Wiley & Sons, Ltd.
A taxonomy of model structures for economic evaluation of health technologies
Authors: Brennan Alan , Chick Stephen E. , Davies Ruth 
Published: August 2006

AbstractModels for the economic evaluation of health technologies provide valuable information to decision makers. The choice of model structure is rarely discussed in published studies and can affect the results produced. Many papers describe good modelling practice, but few describe how to choose from the many types of available models. This paper develops a new taxonomy of model structures. The horizontal axis of the taxonomy describes assumptions about the role of expected values, randomness, the heterogeneity of entities, and the degree of non‐Markovian structure. Commonly used aggregate models, including decision trees and Markov models require large population numbers, homogeneous sub‐groups and linear interactions. Individual models are more flexible, but may require replications with different random numbers to estimate expected values. The vertical axis of the taxonomy describes potential interactions between the individual actors, as well as how the interactions occur through time. Models using interactions, such as system dynamics, some Markov models, and discrete event simulation are fairly uncommon in the health economics but are necessary for modelling infectious diseases and systems with constrained resources. The paper provides guidance for choosing a model, based on key requirements, including output requirements, the population size, and system complexity. Copyright © 2006 John Wiley & Sons, Ltd.
Minimally invasive endoscopic resection of the submandibular gland: A new approach
Authors: Chen Mu‐Kuan , Su Chin‐Chuan , Tsai Yao‐Lung , Chang Cheng‐Chaun 
Published: August 2006

AbstractBackground.This study evaluates the benefits of a new approach, endoscopic resection of the submandibular gland through the hyoid midline level skin incision by use of an ultrasonically activated scalpel.Methods.Twelve operations for patients presenting with submandibular gland disease were performed via minimally invasive endoscopic resection by a single surgeon (M‐KC).Results.All 12 submandibular gland resections were successfully performed endoscopically, and no conversions to conventional open resection were necessary. Of the 12 patients who underwent excision, 3, 6, and 3 had mixed tumor, sialoadenitis with sialolithiasis, and chronic sialoadenitis, respectively. The procedures lasted 50 to 125 minutes (median duration, 70 minutes). No complications associated with the operation occurred, and the scar was almost invisible because of its concealed location with the neck in the natural position.Conclusions.Endoscopic resection of the submandibular gland is a feasible method for treatment of benign lesions. The main advantages of this procedure are that the small operative scar is concealed in the submental skin crease, resulting in improved cosmetic results and minimization of the possibility of facial nerve injury. © 2006 Wiley Periodicals, Inc.
