Des valeurs organisationnelles à la mobilisation des ressources humaines
Authors: Quenneville Nadine , Bentein Kathleen , Simard Gilles 
Published: June 2010

AbstractThis study examines the relationship of perceived organizational values to employee mobilization behaviours as mediated by perceived organizational support (POS) and affective organizational commitment. Firstly, a scale comprising three types of perceived organizational values (interpersonal values, formal values, and individual well‐being‐centered values) was developed and validated using a sample of 580 employees. Secondly, the relationships among variables were examined using structural equations modeling on an independent sample of 260 employees. POS mediated the relationship between employees' perceptions that their organization values the individual well‐being of its members and their affective organizational commitment, which in turn mediated the relationship between POS and individual mobilization behaviours. The contributions of these findings to advancing scholarship and practice are discussed. Copyright © 2010 ASAC. Published by John Wiley & Sons, Ltd.
The Effect of Pulmonary Hypertension on Left Ventricular Diastolic Function in Chronic Obstructive Lung Disease: A Tissue Doppler Imaging and Right Cardiac Catheterization Study

Published: June 2010

AbstractBackgroundPulmonary hypertension (PH) caused by chronic obstructive lung disease (COLD) essentially involves the right heart. Also left ventricular (LV) systolic and diastolic functions may be affected.ObjectivesThe aim of this study was to investigate the effect of on LV diastolic function in patients with COLD.MethodsA total of 47 patients with COLD and 20 controls were included in this study. All patients underwent Doppler echocardiography, tissue Doppler imaging examinations and right cardiac catheterization. The patients were divided into 2 subgroups according to mean pulmonary arterial pressure (mPAP): patients without PH (group1, n = 25) and with PH (group 2, n = 22). The following measurements were taken: peak velocity of early diastolic filling (E), peak late filling with atrial contraction (A), E/A ratio, deceleration time (DT) of E, isovolumic relaxation time (IVRT), early (Em) and late (Am) diastolic mitral lateral annulus velocity.ResultsMitral E/A < 1 and Em < 8 cm/sec were higher in group 2 than in group 1 and the control group. There were significant correlations between mPAP and both mitral E/A (r:− 0.60) and Em (r:− 0.45). In multivariate model, mPAP was not found to be significant on mitral E/A ratio < 1, but there was a significant effect on mitral Em < 8 cm/sec (odds ratio [OR]:1.14, P < 0.05).ConclusionThis study shows that LV diastolic dysfunction in COLD is closely correlated to PH levels. Although increased mPAP may affect the mitral E/A ratio, it seems to have no effect on mitral E/A < 1, whereas it has an independent effect on Em < 8 cm/sec. Copyright © 2010 Wiley Periodicals, Inc.
Improved survival is associated with treatment at high‐volume teaching facilities for patients with advanced stage laryngeal cancer
Authors: Chen Amy Y. , Fedewa Stacey , Pavluck Alex , Ward Elizabeth M. 
Published: June 2010

AbstractBACKGROUND:Because of the multidisciplinary nature of treatment for advanced laryngeal cancer, the authors hypothesized that treatment at high‐volume teaching/research facilities is associated with improved survival.METHODS:After exclusions, 19,326 patients who were diagnosed with advanced laryngeal cancer (stage III and IV) between 1996 and 2002 and who received treatment (chemoradiotherapy [CRT], total laryngectomy [TL], or radiotherapy [RT]) were analyzed from the National Cancer Database (NCDB). Facilities were classified into 6 groups (low‐volume and high‐volume teaching/research facilities, low‐volume and high‐volume community cancer centers, and low‐volume and high‐volume community facilities). Multivariate proportional hazards regression modeling was used to determine 90‐day, 365‐day, and 4‐year hazard ratio (HR) estimates.RESULTS:Treatment included TL (37.6%), CRT (29.4%), and RT alone (33%). Overall, 36.2% of patients were treated at high‐volume teaching/research centers (average, 17.1 cases per year). Among all patients, 20% died within the first year. In multivariate models that were controlled for covariates, 90‐day, 365‐day, and 4 year HR estimates for death were lowest for high‐volume teaching/research centers.CONCLUSIONS:Receiving treatment at high‐volume teaching/research facilities was associated with improved survival. Undergoing total laryngectomy also was associated with improved survival. The current results suggested that the regionalization of care for patients with advanced‐stage laryngeal cancer has occurred, because most patients were treated either at high‐volume teaching/research facilities or at high‐volume community cancer centers. Future studies should investigate the factors associated with better survival at high‐volume teaching/research facilities, such as quality of care, processes of care, and referral patterns.

Authors: Momm Felix , Kaden Markus , Tannock Ian , Schumacher Martin , Hasse Joachim , Henke Michael 
Published: June 2010

AbstractBACKGROUND:The current study was conducted to evaluate the maximum tolerable dose of weekly gemcitabine administered simultaneously with radiation and cisplatin in patients with locally advanced nonsmall cell lung cancer (NSCLC).METHODS:Patients with stage IIIA/B NSCLC received concurrently 63 grays radiation and 20 mg/m2 cisplatin Day 1 to 3 in Weeks 1 and 5, plus weekly gemcitabine at escalating doses (150‐700 mg/m2) on Fridays after radiation to avoid radiosensitization. The authors assessed dose‐limiting toxicities according to Common Toxicity Criteria. The primary endpoint was maximum tolerated dose (MTD) of gemcitabine. Tumor resectability, survival, and disease‐free survival (DFS) were also determined.RESULTS:Forty‐two patients were accrued, of whom 95% received radiation and 66% cisplatin as above. Weekly doses of gemcitabine were escalated to 700 mg/m2. Grade 3 dysphagia and 1 case of fatal, probably treatment‐related pulmonary deterioration established the MTD of gemcitabine at 550 mg/m2 weekly. Twenty‐five patients underwent surgery, and histopathological complete regression was documented in 26% of these patients. Overall, median actuarial survival and DFS were 23.8 and 12.4 months, respectively.CONCLUSIONS:Gemcitabine at doses up to 550 mg/m2 weekly can be given simultaneously with radiation and cisplatin to patients with locally advanced NSCLC. Radical resection thereafter is feasible. The impact of this aggressive therapy should be evaluated further. Cancer 2010. © 2010 American Cancer Society.

Authors: Azaiza Faisal , Cohen Miri , Awad Mariam , Daoud Francoise 
Published: June 2010

AbstractBACKGROUND:The current study was conducted to assess screening behaviors in relation to cultural and environmental barriers among Palestinian women in the West Bank.METHODS:The participants were 397 women, ages 30 to 65 years, residing in the Palestinian Authority, and a stratified sample method was used (98.3% participation rate). The participants completed questionnaires on breast examination behaviors and knowledge, on perceived cancer fatalism and health beliefs, and on environmental barriers scales.RESULTS:Greater than 70% of the women had never undergone mammography or clinical breast examination (CBE), whereas 62% performed self breast examination (SBE). Women were more likely to undergo mammography if they were less religious (odds ratio [OR], 0.59; 95% confidence interval [95% CI], 0.47‐0.81) and if they expressed lower personal barriers (OR, 0.59; 95% CI, 0.29‐0.76) and lower fatalism (OR, 0.39; 95% CI, 0.28‐0.63). A higher likelihood for CBE was related to being Christian (OR, 2.91; 95% CI, 1.49‐5.73) and being less religious (OR, 0.32; 95% CI, 0.13‐0.78), to perceived higher effectiveness of CBE (OR, 1.46; 95% CI, 1.20‐1.79), and to perceived lower cancer fatalism (OR, 0.35; 95% CI, 0.28‐0.60). Women were more likely to perform SBE if they were more educated, resided in cities, were Christian, were less religious, had a first‐degree relative with breast cancer, perceived higher effectiveness and benefits of SBE, and perceived lower barriers and fatalism.CONCLUSIONS:Participants reported a combination of personal, cultural, and environmental barriers, which should be addressed by educational programs and followed by the allocation of resources for early detection and treatment of breast cancer.

Published: June 2010

AbstractWe present resonant Raman measurements on single‐walled carbon nanotubes (SWCNT) functionalized with propylamine groups at different degrees. Direct nucleophilic addition based on in situ generated primary amides is used for attaching n‐propylamine to the sidewalls of SWCNTs. The influence of the amino functionalities on the electronic structure of the nanotubes is investigated. From the Raman resonance profiles of the radial breathing modes (RBMs), the chiral indices of the corresponding tubes are assigned. We observe significant redshifts of the transition energies and a broadening of the resonance windows due to chemical modification of SWCNTs. Similar redshifts are derived from the analysis of the NIR/Vis transmission spectrum. The relative Raman intensities of the functionalized samples and the evaluation of their transmission spectra indicate a diameter dependence of the reactivity as it has been observed for other moieties. By analyzing the defect induced D mode we observe a considerable degree of functionalization accompanied by an almost unharmed tube structure, which ensures that the observed effects are mainly driven by changes of the electronic structure.

Published: June 2010

AbstractIn ascidian Ciona intestinalis, a subset of trunk epidermal neurons were shown to possess external network of neural projections. To characterize a more complete network in naturally hatched (chorionated) larvae, we visualized the structure with a confocal laser scanning microscope. High resolution images revealed the huge network consisting of several subnetworks in whole‐larval tunic. We named this network the ASNET (ascidian dendritic network in tunic). The ASNET was dynamically generated and collapsed during larval stages. Interestingly, one of the subnetworks found around apical trunk epidermal neurons was bilaterally asymmetric. In caudal epidermal neurons, transmission electron microscopy revealed that 9+2 axonemes were accompanied by a vesicle‐containing mass in the ASNET arbor, but the distal end of the arbor contained only the vesicle‐containing fibrous mass and no 9+2 axonemes. The characteristics of the ASNET suggest that it forms a unique outer body network in the ascidian larval tunic. Developmental Dynamics 239:2278–2287, 2010.© 2010 Wiley‐Liss, Inc.
Quantum Chemical Design for Enhanced Second‐Order NLO Response of Terpyridine‐Substituted Hexamolybdates
Authors: Janjua Muhammad Ramzan Saeed Ashraf , Guan Wei , Yan Likai , Su Zhong‐Min , Karim Abdul , Akbar Jamshed 
Published: June 2010

AbstractA dramatic increase in the second‐order nonlinear optical (NLO) response of terpyridine‐substituted hexamolybdates has been observed from 886.55 × 10–30 esu (system 1) to 4622.92 × 10–30 esu (system 7). The dipole polarizabilities and second‐order nonlinear optical (NLO) properties of terpyridine derivatives of hexamolybdates have been investigated by using time‐dependent density functional theory (TDDFT). The quantum mechanical design suggests that [Mo6O18(N4C25H14(CF3)2 (CN)2)]2– (system 7) is the best choice among all studied systems to improve nonlinearity. The electron‐withdrawing ability of electron‐acceptor groups (F, Cl, Br, I, CF3, and CN) at the end of the terpyridine ligand directs the charge transfer (CT) from the POM cluster to the terpyridine segment along the z axis, which leads to an efficient second‐order NLO molecular design. These small changes in molecular composition by substitution may have disproportionately huge effects on the NLO properties, which can be attributed to the so‐called “butterfly effect”.
Orthogonal Regioselective Synthesis of N‐Alkyl‐3‐substituted Tetrahydroindazolones (Eur. J. Org. Chem. 20/2010)
Authors: Kim Jonghoon , Song Heebum , Park Seung Bum 
Published: June 2010

AbstractThe cover picture shows that the logical introduction of three reaction components can lead to the magical control of regiochemistry in biologically important N‐alkyl‐3‐substituted tetrahydroindazolones. This divergent strategy allows the robust and orthogonal regioselective synthesis of highly functionalized tetrahydroindazolones from Boc‐protected alkylhydrazines. Details are discussed in the article by S. B. Park et al. on p. 3815 ff. This paper is dedicated to the late Professor Chi Sun Hahn in admiration of his contributions to the field of organic chemistry in Korea.

Published: June 2010

AbstractThe standardization of methods for human body fluid protein isolation is a critical initial step for proteomic analyses aimed to discover clinically relevant biomarkers. Several caveats have hindered pancreatic fluid proteomics, including the heterogeneity of samples and protein degradation. We aim to optimize sample handling of pancreatic fluid that has been collected using a safe and effective endoscopic collection method (endoscopic pancreatic function test). Using SDS‐PAGE protein profiling, we investigate (i) precipitation techniques to maximize protein extraction, (ii) auto‐digestion of pancreatic fluid following prolonged exposure to a range of temperatures, (iii) effects of multiple freeze–thaw cycles on protein stability, and (iv) the utility of protease inhibitors. Our experiments revealed that TCA precipitation resulted in the most efficient extraction of protein from pancreatic fluid of the eight methods we investigated. In addition, our data reveal that although auto‐digestion of proteins is prevalent at 23 and 37°C, incubation on ice significantly slows such degradation. Similarly, when the sample is maintained on ice, proteolysis is minimal during multiple freeze–thaw cycles. We have also determined the addition of protease inhibitors to be assay‐dependent. Our optimized sample preparation strategy can be applied to future proteomic analyses of pancreatic fluid.
Electrophoretically mediated microanalysis for the evaluation of interspecies variation in cholinesterase metabolism
Authors: Moura Joana , Simplício Ana Luísa 
Published: June 2010

AbstractThis study describes an electrophoretically mediated microanalysis method, suitable for the preclinical evaluation of the hydrolysis of ester drugs by the serum of different animals and for further characterization of human–animal correlation. Dog, cat, cow, horse, sheep, rat and human serum were diluted (25%) in the appropriate buffer and replaced the enzyme solution usually used in electrophoretically mediated microanalysis methods for the study of enzyme kinetics. They were then compared in terms of the ability to hydrolyze acetylthiocholine and butyrylthiocholine (0.25 mM) by in‐capillary reaction. Human serum afforded the highest conversion rates (52% butyryltiocholine and 34% acetylthiocholine) followed by horse (31 and 35%), dog (26 and 24%), cat (22 and 14%), rat (11 and 15%) and sheep (8 and 8%). Hydrolysis by bovine serum was negligible. The method is fast (under 8 min including rinsing steps), sensitive (under 25 μM substrate could be quantified) and repeatable (RSD≈2%), only requiring minute amounts of sample.
