Measurement of responses to suggestions for relaxation by means of indirect and direct tests
Authors: Gheorghiu Vladimir A. , Molz Günter 
Published: June 2008

AbstractFirst, some analytic characterizations of suggestibility as well as a brief summary of recent developments of tests and scales for suggestibility without hypnosis are provided. Following that summary, an empirical study on the development of a relaxation tool both for induction and measurement is described that does not make use of the terms ‘suggestion’ and ‘hypnosis’. The objective was to measure suggestibility and relaxation that may correlate to these two approaches. This instrument consists of indirect motor items which are supposed to induce relaxation in an implicit manner and mental items inducing relaxation in an explicit way. In order to assess its psychometric quality this scale was administered to 177 school children (aged between 10 and 21 years). Item difficulties, item‐total‐correlations and reliability had satisfactory psychometric qualities. The correlation between these scales was moderate (r = 0.37). Finally, the strategy for further development of the scales is outlined. Copyright © 2008 British Society of Experimental & Clinical Hypnosis. Published by John Wiley & Sons, Ltd.
Cytomorphologic features of well‐differentiated papillary mesothelioma in peritoneal effusion: A case report
Authors: Ikeda Katsuhide , Suzuki Takao , Tate Genshu , Mitsuya Toshiyuki 
Published: June 2008

AbstractWell‐differentiated papillary mesothelioma (WDPM), a distinct subtype of diffuse malignant mesothelioma, usually occurs in the peritoneum and is seen most commonly in women of reproductive age. Histologic features of WDPM include papillary growth and stout fibrous cores surrounded by a single layer of tumor cells. We present the case of a 73‐year‐old woman without subjective symptoms who showed signs of peritoneal effusion during a routine examination and for whom cytologic examination of the ascitic fluid was performed. Many spherical clusters, with a smooth external surface composed of a single layer of uniform cuboidal cells, were observed. Within each cluster, a collagenous ball showed light green Papanicolaou staining. Immunohistochemistry of surgical specimens showed tumor cells positive for calretinin, D2‐40, and HBME‐1 staining. The histologic diagnosis was WDPM. The identification of a collagenous ball within these clusters is a useful cytologic finding for the diagnosis of WDPM. WDPM should be suspected when numerous collagenous balls are present by effusion cytology and isolated cells are not. Diagn. Cytopathol. 2008;36:512–515. © 2008 Wiley‐Liss, Inc.
Absence of microfollicular basement membrane: A new indicator in the diagnosis of follicular carcinoma thyroid
Authors: Sahoo Maheswar , Chintamani  , Sekhri Tarun , Tripathi Madhabi , Rautela N. , Solanki Y. 
Published: June 2008

AbstractThe thyroid follicles represent a biological continuum. Each follicle is closely related to the follicle that is next to it. The important feature of a follicular carcinoma is a microfollicular pattern. We report a case of follicular carcinoma in a 48‐year‐old female that demonstrates microfollicles which are larger in size and contain more number of follicular cells in cytologic smears (20–29 cells) in contrary to the literature definition of microfollicles containing approximately 6–12 cells. We also demonstrate absence of basement membranes in these microfollicles in histologic sections by Silver Methanamine Stain, which may be an indicator to search for vascular and capsular invasion. This case report also describes postoperative positron emission tomography scan findings. Diagn. Cytopathol. 2008;36:519–522. © 2008 Wiley‐Liss, Inc.
Rapid cell blocks improve accuracy of breast FNAs beyond that provided by conventional cell blocks regardless of immediate adequacy evaluation

Published: June 2008

AbstractA new “rapid cell block” technique (RCB; the predecessor of Cellient™ Automated Cell Block System) is efficient at recovering sparse material. We previously found that RCBs of breast fine‐needle aspirations (FNAs) frequently allow histologic classification of problematic ductal proliferative lesions. Previous studies that did not emphasize cell blocks found that on‐site evaluation (OSE) of breast FNAs improves diagnosis. The purpose of this study was to determine if RCB could replace the utility of OSE of breast FNAs. The study included 604 consecutive ultrasound‐guided noncyst breast FNAs composed of three cohorts based on the presence or absence of immediate adequacy assessment, conventional (collodion bag) cell blocks (CCB), and RCB. The cohort with OSE together with CCB did not perform as well as the cohort without OSE but with RCB. In a third cohort, performance characteristics of RCBs and CCBs were compared in an independent review by two cytopathologists blinded to the final cytology and follow‐up histology diagnosis. By itself, the RCB histologic section was diagnostic 97% of the time, and it provided a diagnostic accuracy superior to CCB by itself and comparable to that provided by the combination of the smears with CCB. Highest accuracy was obtained by combining smears/monolayer preparations and RCB. Replacing OSE with RCBs provided substantial cost savings and savings of time for cytopathologists, radiologists, and their assistants. Diagn. Cytopathol. 2008;36:523–529. © 2008 Wiley‐Liss, Inc.

Published: June 2008

AbstractObjective:Critical first steps in the treatment of anorexia nervosa (AN) include re‐nutrition and weight restoration, both highly anxiety provoking for patients. We explored the impact of progressive muscle relaxation (PMR), guided imagery (GI), self‐directed relaxation (SR), and control (C) on reducing postprandial anxiety in 64 females with AN.Method:Participants began the study upon hospital admission. They received relaxation training after lunch for 15 days. Pre‐ and post‐session anxiety and treatment acceptability ratings were made daily.Results:Although all conditions improved relaxation and decreased anxiety, feelings of fullness, and thoughts about weight, the three active conditions significantly reduced anxiety and increased relaxation more than C (p < .0001). Participants significantly enjoyed the three active treatments, were more likely to recommend them to a friend, and were more likely to use either PMR or GI again versus C (p < .0001).Conclusion:Relaxation may be a valuable component for reducing postprandial anxiety in AN. © 2008 by Wiley Periodicals, Inc.

Sol–Gel Synthesis of Tunable Cerium Titanate Materials
Authors: Martos Mónica , Julián‐López Beatriz , Folgado José Vicente , Cordoncillo Eloisa , Escribano Purificación 
Published: June 2008

AbstractCerium titanate structures present a high technological interest because of their optical and catalytic properties. This work reports the synthesis of these materials by a sol–gel methodology that allows mixed oxides with TiIV/CeIII, TiIV/CeIV or TiIV/CeIII–CeIV species to be obtained. Crystallization of CeO2–TiO2 mixed oxides and Ce2Ti2O7 pyrochlore phase was corroborated by XRD and Raman spectroscopy. Magnetic and EPR measurements were performed in order to clarify the oxidation state of the cerium ions in the system as a result of the easy oxidation of CeIII. The firing atmosphere is crucial for the CeIII/CeIV ratio, which is responsible for the different structure, but it also affects the colouration (yellow, green, brown). This methodology offers the possibility to modulate the Ce3+/Ce4+ content and particle sizes providing more ecological coloured pigments based on rare earth elements that could be interesting materials for advanced applications in catalysis.(© Wiley‐VCH Verlag GmbH & Co.

Published: June 2008

AbstractStarting fromN‐protectedcis‐ andtrans‐2‐aminocyclopent‐3‐enecarboxylic acid derivatives, isomers of 2‐amino‐3‐hydroxycyclopentanecarboxylic acid (8and12) were prepared via oxazoline intermediates, whereas the stereoisomeric 2‐amino‐3,4‐dihydroxycyclopentanecarboxylic acids14and17were synthesized by OsO4‐catalyzed oxidation. The enantiomers of8and14were also prepared by the same pathway. The structures, stereochemistry and relative configurations of the synthesized compounds were proved by NMR spectroscopy.

Published: June 2008

AbstractBackgroundSomatic mutations in the tyrosine kinase domain of the epidermal growth factor receptor (EGFR) are involved in tumorigenesis and response to targeted therapies in distinct cancer types. Squamous cell carcinomas of the head and neck (HNSCC) show an incidence of EGFR mutations varying from 7% in Asians to 0% to 4% in white patients. Mutational screening predominantly focuses on the analysis of hotspot regions of EGFR (exons 19 and 21).MethodsIn a follow‐up study, we screened for mutations in exons 18 to 21 of the EGFR gene in 127 patients.ResultsIn this cohort, a mutation frequency of 2.4% (3/127) was detected. In addition to the previously reported mutation p.K745R, the otherwise rare EGFR mutation p.G796S occurred in 2 patients with HNSCC (2/127).ConclusionEGFR kinase mutations are rare in white patients with HNSCC. Extension of mutational screening to exon 20 may clarify the frequency and impact of the mutation p.G796S. © 2008 Wiley Periodicals, Inc. Head Neck, 2008

Published: June 2008

AbstractBackgroundThe main concern in the treatment of laryngeal carcinomas is tumor control with preservation of laryngeal functions. We believe that salvage supracricoid partial laryngectomy (SPL) should be carefully considered in selected cases of radiotherapy failure, because it can offer the possibility of achieving adequate tumor control with preservation of laryngeal functions.MethodsA series of 31 patients who underwent an SPL as salvage procedure after radiotherapy failure was reviewed.ResultsLocoregional control rate was 75%, with 60% 5‐year overall survival; no patients were lost to follow‐up, and a death‐from‐disease rate of 19.35% was recorded. Restoration of laryngeal functions was achieved in 89.29% of the patients. No statistically significant differences were found in locoregional control regarding anterior commissure involvement, elective neck dissection versus wait‐and‐see policy, pathologic positive neck disease, and restage I–II versus restage III–IV.ConclusionThe oncologic and functional results indicate the consistency of salvage SPL, proposing this type of operation as a serious alternative to total laryngectomy in carefully selected cases. © 2008 Wiley Periodicals, Inc.

Published: June 2008

AbstractBackgroundSuccessful free flap surgery in the head and neck is dependent on the successful anastomosis of both artery and vein. The success of all free flaps was analyzed to determine the necessity for performing 2 venous anastomoses.MethodsWe retrospectively analyzed a single surgeon's 10‐year experience (August 1993–August 2003) in free flap reconstruction for malignant tumors of the head and neck. Four hundred ninety‐two free flaps were primary reconstructions that did not require a vein graft, vein loop, or cephalic turnover procedure. Three hundred forty‐five flaps had 1 venous anastomosis, and 147 flaps had 2 venous anastomoses.ResultsOverall, flap success was 468 of 492 (95.1%). Successful flap reconstruction in patients undergoing 2 venous anastomoses was 145 of 147 (98.6%) compared with 323 of 345 (93.6%) in patients undergoing 1 anastomosis (p < .05).ConclusionWhere possible, a second venous anastomosis should be performed in head and neck free flap reconstruction. © 2008 Wiley Periodicals, Inc.

Mouse chromosome 11 harbors genetic determinants of hippocampal strain‐specific nicotinic receptor expression

Published: June 2008

AbstractDifferences between isogenic mouse strains in cellular expression of the neuronal nicotinic acetylcholine (ACh) receptor subunit alpha4 (nAChRα4) by the dorsal hippocampus are well known. To investigate further the genetic basis of these variations, expression of the nAChRα4 subunit was measured in congenic mouse lines derived from two strains exhibiting notable divergence in the expression of this subunit: C3H and C57BL/6. Congenic lines carrying reciprocally introgressed regions (quantitative trait loci; QTL) from chromosomes 4, 5, and 12 each retained the phenotype most closely associated with the parental strain. However, in congenic lines harboring the reciprocal transfer of a chromosome 11 QTL, a characteristic difference in the ratio of interneurons versus astrocytes expressing nAChRα4 in the CA1 region is reversed relative to the parental strain. These finding suggest that this chromosomal segment harbors genes that regulate strain distinct hippocampal morphology that is revealed by nAChRα4 expression. © 2008 Wiley‐Liss, Inc.
A coupled vertically integrated model to describe lateral exchanges between surface and subsurface in large alluvial floodplains with a fully penetrating river

Published: June 2008

AbstractThis paper presents a vertically averaged model for studying water and solute exchanges between a large river and its adjacent alluvial aquifer. The hydraulic model couples horizontal 2D Saint Venant equations for river flow and a 2D Dupuit equation for aquifer flow. The dynamic coupling between river and aquifer is provided by continuity of fluxes and water level elevation between the two domains. Equations are solved simultaneously by linking the two hydrological system matrices in a single global matrix in order to ensure the continuity conditions between river and aquifer and to accurately model two‐way coupling between these two domains. The model is applied to a large reach (about 36 km2) of the Garonne River (south‐western France) and its floodplain, including an instrumented site in a meander. Simulated hydraulic heads are compared with experimental measurements on the Garonne River and aquifer in the floodplain. Model verification includes comparisons for one point sampling date (27 piezometers, 30 March 2000) and for hydraulic heads variations measured continuously over 5 months (5 piezometers, 1 January to 1 June 2000). The model accurately reproduces the strong hydraulic connections between the Garonne River and its aquifer, which are confirmed by the simultaneous variation of the water level in the river and in piezometers located near the river bank. The simulations also confirmed that the model is able to reproduce groundwater flow dynamics during flood events. Given these results, the hydraulic model was coupled with a solute‐transport component, based on advection‐dispersion equations, to investigate the theoretical dynamics of a conservative tracer over 5 years throughout the 36 km2 reach studied. Meanders were shown to favour exchanges between river and aquifer, and although the tracer was diluted in the river, the contamination moved downstream from the injection plots and affected both river banks.

Assessing factors that influence spatial variations in duff moisture
Authors: Raaflaub L. D. , Valeo C. 
Published: June 2008

AbstractPatterns and spatial variations in the moisture of the decomposing organic matter on the forest floor (the duff) of a montane forest were analysed in an effort to determine the primary factors shaping these patterns. Above and below canopy meteorological conditions were monitored to determine the influence of canopy cover on duff moisture. The spatial and temporal distributions of duff moisture were assessed through daily duff moisture measurements collected at regular intervals in ten 10 × 10 m plots representing a variety of canopy types and densities. Meteorological conditions ranged from very wet to very dry and resulted in duff moisture variations that were more pronounced during wet periods than in extended periods of drying. Investigations on the influence of canopy type, tree density, and tree proximity on duff moisture patterns indicated that canopy type and tree proximity are the most important factors affecting duff moisture. Interception seems to be the primary controller of duff moisture patterns with an influence at the centimetre scale. Copyright © 2008 John Wiley & Sons, Ltd.

Published: June 2008

AbstractC‐reactive protein is a sensitive but nonspecific systemic marker of inflammation. Several prospective studies have investigated the association of prediagnostic circulating C‐reactive protein concentrations with the development of colorectal cancer, but the results have been inconsistent. We performed a systematic review of prospective studies of the association between prediagnostic measurements of circulating high‐sensitivity C‐reactive protein and development of invasive colorectal cancer. Authors of original studies were contacted to acquire uniform data. We combined relative risks (RR) for colorectal cancer associated with a one unit change in natural logarithm‐transformed high‐sensitivity C‐reactive protein using inverse variance weighted random effects models. We identified eight eligible studies, which included 1,159 colorectal cancer cases and 37,986 controls. The summary RR per one unit change in natural log‐transformed high‐sensitivity C‐reactive protein was 1.12 (95% confidence intervals [CI], 1.01–1.25) for colorectal cancer, 1.13 (95% CI, 1.00–1.27) for colon cancer, and 1.06 (95% CI, 0.86–1.30) for rectal cancer. The association was stronger in men (RR, 1.18; 95% CI, 1.04–1.34) compared to women (RR, 1.09; 95% CI, 0.93–1.27) but this difference was sensitive to the findings from a single study. Prediagnostic high‐sensitivity C‐reactive protein concentrations were weakly associated with an increased risk for colorectal cancer. More work is needed to understand the extent to which circulating high‐sensitivity C‐reactive protein or other blood inflammatory markers are related to colonic inflammation. © 2008 Wiley‐Liss, Inc.
Long‐term mortality from pleural and peritoneal cancer after exposure to asbestos: Possible role of asbestos clearance

Published: June 2008

AbstractModels based on the multistage theory of carcinogenesis predict that the rate of mesothelioma increases monotonically as a function of time since first exposure (TSFE) to asbestos. Predictions of long‐term mortality (TSFE ≥ 40 years) are, however, still untested, because of the limited follow‐up of most epidemiological studies. Some authors have suggested that the increase in mesothelioma rate with TSFE might be attenuated by clearance of asbestos from the lungs. We estimated mortality time trends from pleural and peritoneal cancer in a cohort of 3,443 asbestos‐cement workers, followed for more than 50 years. The functional relation between mesothelioma rate and TSFE was evaluated with various regression models. The role of asbestos clearance was explored using the traditional mesothelioma multistage model, generalized to include a term representing elimination over time. We observed 139 deaths from pleural and 56 from peritoneal cancer during the period 1950–2003. The rate of pleural cancer increased during the first 40 years of TSFE and reached a plateau thereafter. In contrast, the rate of peritoneal cancer increased monotonically with TSFE. The model allowing for asbestos elimination fitted the data better than the traditional model for pleural (p = 0.02) but not for peritoneal cancer (p = 0.22). The risk for pleural cancer, rather than showing an indefinite increase, might reach a plateau when a sufficiently long time has elapsed since exposure. The different trends for pleural and peritoneal cancer might be related to clearance of the asbestos from the workers' lungs. © 2008 Wiley‐Liss, Inc.

Published: June 2008

AbstractWe describe the application of a special purpose board for molecular dynamics simulations, named MDGRAPE‐3, to the problem of simulating periodic bio‐molecular systems. MDGRAPE‐3 is the latest board in a series of hardware accelerators designed to calculate the nonbonding long‐range interactions much more rapidly than normal processors. So far, MDGRAPEs were mainly applied to isolated systems, where very many nonbonded interactions were calculated without any distance cutoff. However, in order to regulate the density and pressure during simulations of membrane embedded protein systems, one has to evaluate interactions under periodic boundary conditions. For this purpose, we implemented the Particle–Mesh Ewald (PME) method, and its approximation with distance cutoffs and charge neutrality as proposed by Wolf et al., using MDGRAPE‐3. When the two methods were applied to simulations of two periodic biomolecular systems, a single MDGRAPE‐3 achieved 30–40 times faster computation times than a single conventional processor did in the both cases. Both methods are shown to have the same molecular structures and dynamics of the systems. © 2008 Wiley Periodicals, Inc. J Comput Chem 2009
