AbstractWe have successfully controlled the shape of gold nanocrystals through a simple and low‐cost hydrothermal method based on a modified polyol process. Well‐defined gold nanocrystals of icosahedral shape were synthesized in high yields by the rapid reduction of gold precursors with ethylene glycol (EG) in the presence of poly(vinyl pyrrolidone) (PVP) under hydrothermal conditions for 1 h. Truncated icosahedra (football‐shaped) have been prepared for the first time by prolonging the reaction time to 4 h. Both nanocrystal shapes were obtained quantitatively. Addition of citric acid inhibits the shape‐change process (from icosahedron to truncated icosahedron) by blocking oxidative etching, while addition of Fe(III) facilitates the shape‐change process by enhancing oxidative etching. We propose that growth of truncated icosahedra can be induced and maintained through interplay of the following processes: generation of multiple twinned seeds, shape‐ and size‐focusing by Ostwald ripening, and oxidative etching and preferential growth on the {100} face.
Reaction monitoring of the MMA polymerization at marginal dispersion stability
Authors: Mantelis Charalampos A. , Meyer Thierry 
Published: December 2007

AbstractThe free‐radical dispersion polymerization of methyl methacrylate was studied using the reaction calorimetry technique. An especially developed calorimeter for use with supercritical fluids was employed and a set of experiments was explicitly designed to isolate the effect of the pressure. It was found that, under marginal dispersion stability conditions, small pressure changes can have significant effects on the reaction evolution. The pressure was also found to affect the partitioning of the monomer between the two reaction phases. The heat released during the nucleation stage of the reaction was measured for the first time and permitted the discussion on the polymerization locus during this stage. © 2007 American Institute of Chemical Engineers AIChE J, 2008

Published: January 2008

AbstractBACKGROUND:Esophageal atresia with or without tracheoesophageal fistula (EA/TEF) and congenital diaphragmatic hernia (CDH) are severe congenital anomalies. Their etiologies are mostly unknown and are thought to be multifactorial. No specific environmental factors have consistently been described as risk factors.METHODS:In a study conducted during the years 2000 to 2004 in a pediatric surgical referral center in the Netherlands, parents of children with EA/TEF or with CDH of the Bochdalek type and parents of a group of children without major birth defects filled out a questionnaire about possible exposure to environmental risk factors during the period from 1 month before conception to the end of the first trimester of pregnancy. Children with chromosomal anomalies were excluded.RESULTS:Questionnaires were returned for 47 out of 64 cases (73%) with EA/TEF, for 63 out of 77 cases (82%) with CDH, and for 202 out of 243 controls (83%). In EA/TEF, maternal age was borderline significantly higher than in controls (32.2 vs. 30.6 years, p = .05). Contact with herbicides or insecticides was associated with EA/TEF in univariate analysis (OR 2.0; 95% CI: 1.0–4.1) and in multivariate analysis, although of borderline significance. In univariate analysis, CDH was significantly associated with maternal use of alcohol (OR 2.9; 95% CI: 1.6–5.2).CONCLUSIONS:We found a significant association between maternal alcohol use around the time of conception and CDH. A possible explanation might be the effect of alcohol on the retinoic acid pathway. An association was found between contact with herbicides or insecticides and EA/TEF.

The landscape of hypnosis in France in the twentieth century
Authors: Guilloux Christine 
Published: January 2008

AbstractThe author – a psychologist, psychotherapist and poetess – traces the history of hypnosis in France, the cradle of hypnosis. At the outset there were two conflicting schools, one originating with Charcot, a neurologist, who ended viewing hypnosis as a pathologic phenomenon associated with hysteria; the other with therapeutic goals originating with Bernheim and viewing hypnosis as a physiological state involving suggestion. From 1900 psychoanalysis dominated until the mid‐century when Chertok and later Michaux struggled to stimulate a revival. In 1980 they founded the Groupement d'Etudes pour les Applications Médicales de l'Hypnose (GEAMH) for research and training purposes, which continues to host conferences to the present day. In 1983 Godin and Malarewicz established in Paris the first Milton H. Erickson Institute, and there followed a proliferation of institutes throughout France. From 1991 Roustang wrote prolifically offering an original Eastern and Western synthesis and therapeutic approach. In 1997 Bellet founded the Confédération Francophone d'Hypnose et de Thérapies Brèves (CFHTB) drawing together, by 2007, 21 affiliated organizations with 3000 practitioners in France, Belgium, Switzerland and Québec, and with affiliation with international societies.

Authors: Kim Hwan Myung , Kim Bo Ra , An Myoung Jin , Hong Jin Hee , Lee Kyoung J. , Cho Bong Rae 
Published: January 2008

Abstract2‐Acetyl‐6‐(dimethylamino)naphthalene‐derived two‐photon fluorescent Ca2+ probes (ACa1–ACa3) are reported. They can be excited by a 780 nm laser beam, show 23–50‐fold enhancement in one‐ and two‐photon excited fluorescence in response to Ca2+, emit fourfold stronger two‐photon excited fluorescence than Oregon Green 488 BAPTA‐1 upon complexation with Ca2+, and can selectively detect intracellular free Ca2+ ions in live cells and living tissues with minimum interference from other metal ions and membrane‐bound probes. Moreover, these probes are capable of monitoring calcium waves at a depth of 120–170 μm in live tissues for 1100–4000 s using two‐photon microscopy with no artifacts of photobleaching.
Solution‐focused mediation: The future with a difference
Authors: Bannink Fredrike P. 
Published: January 2008

AbstractRather than dwelling on the conflict, solution‐focused mediation asks: What would you prefer instead of the conflict? The focus is on the desired outcome: the future with a difference. Clients are considered capable of formulating their own goal and of devising solutions. The expertise of the mediator lies in asking questions that help clients in this respect and that motivate clients to change. This article demonstrates that concept and the methodology differ significantly from other types of mediation. Conversations become increasingly positive and shorter, ensuring that solution‐focused mediation is also cost‐effective.
Identification and hormonal regulation of a novel form of NKp30 in human endometrial epithelium
Authors: Ponnampalam Anna P. , Gargett Caroline E. , Rogers Peter A. W. 
Published: December 2007

AbstractThis study reports the discovery and steroid hormonal regulation of a novel glycosylated form of NKp30 in human endometrial epithelium. NKp30 is a member of the immunoglobulin superfamily and one of three existing natural cytotoxicity‐triggering receptors. NKp30 is a glycosylated protein and is thought to be selectively expressed in resting and activated natural killer cells. The aims of the present study were to fully characterize NKp30 mRNA and protein in human endometrium during the menstrual cycle, and to investigate the hormonal regulation of NKp30. NKp30 mRNA was significantly up‐regulated in fresh tissues during late secretory phase of the menstrual cycle. Interestingly, NKp30 mRNA was also present in clonally derived endometrial epithelial cells (CEE) in comparable amounts to fresh tissue. NKp30 protein was predominantly found in the endometrial glands and luminal epithelia of the secretory phase endometrium. Western blotting and de‐glycosylation studies show that a novel glycosylated form of NKp30 is present in endometrial epithelium and that it can dimerize. Further phenotyping of CEE by flow cytometry revealed that they are CK8+CD49f+NKp30+CD45–CD56–. The data also show that transcription and translation of the novel form of NKp30 can be induced by progesterone treatment after 48 h in endometrial explants in vitro. This is the first report to show the presence of both NKp30 mRNA and a novel glycosylated form of NKp30 protein in endometrial epithelial cells.

Authors: Bibby Jessica R. L. , Cotton Susan M. , Perry Alison , Corry June F. 
Published: December 2007

AbstractBackground.This is the first prospective study to use instrumental and both clinician‐ and client‐rated auditory‐perceptual measures to examine voice and voice‐related quality of life changes in patients after curative radiotherapy for early glottic cancer.Method.Thirty patients undergoing curative radiotherapy treatment for early glottic cancer completed the following: 3 voice tasks for acoustic, aerodynamic, and auditory‐perceptual voice measures (therapist‐rated); a patient self‐report rating of voice quality; and a voice‐related quality of life assessment before and 12 months after radiotherapy.Results.Patients' perceptions of their voice quality and their voice‐related quality of life significantly improved posttreatment, as did acoustic, aerodynamic, and auditory‐perceptual voice measures. Mean speaking fundamental frequency did not change significantly, although breathiness and strain in the voice recordings were demonstrably reduced.Conclusion.In describing postradiotherapy voices in this study, pertinent measures of voice outcomes have been established, setting the benchmark for comparison in future cohort studies. © 2007 Wiley Periodicals, Inc.

Published: December 2007

AbstractBackground.We evaluated the effectiveness of intraarterial methotrexate infusion as a primary therapy for oral verrucous carcinoma (VC).Methods.Fifteen male patients (mean age, 55 years) were included. By using an implantable port‐catheter system and a portable pump, methotrexate was continuously infused to the external carotid artery for a mean period of 7.5 days (50 mg/day), followed by weekly bolus of methotrexate (25 mg) via intraarterial route for a mean period of 10 weeks.Results.The tumor regressed dramatically and disappeared completely after treatment within a mean period of 2.5 months. All patients obtained complete remission and recovered without disfigurement. All patients were alive without disease recurrence at a median follow‐up of 43 months. The side effects were tolerable.Conclusions.The results of our treatment modality for oral VC appear to compete favorably with the results of surgical series and even more with those of radiotherapy series. © 2007 Wiley Periodicals, Inc.

Published: December 2007

AbstractThrough health sector reform in developing countries, Ministries of Health have sought to enhance health care through greater community governance and improved management effectiveness in their public hospitals. In this paper, we present a partnership‐mentoring model for enhancing management capacity that has been piloted in Ethiopia and may be useful in other developing countries. The model included needs assessment and baseline evaluation using a hospital management indicator checklist, deployment of 24 Fellows (US and international hospital administrators) for 1 year to work as mentors with hospital management teams in 14 Ethiopian hospitals, continuing didactic and practical training in quality improvement methods for hospital management teams, and 24 management improvement projects to be completed during the year with plans for replication more broadly as appropriate. Surveys of Fellows and Ethiopian managers within the first quarter of onsite activity found high levels of trust in one another's abilities and intent to implement changes. The partnership‐mentoring model promotes sustainability and may provide other countries with approaches for improving the quality of hospital care through improved hospital management.

The relationship between R&D collaboration, subsidies and R&D performance: Empirical evidence from Finland and Germany
Authors: Czarnitzki Dirk , Ebersberger Bernd , Fier Andreas 
Published: December 2007

AbstractThis study focuses on the impact of innovation policies and R&D collaboration in Germany and Finland. We consider collaboration and subsidies as heterogeneous treatments, and perform an econometric matching to analyze R&D and patent activity at the firm level. In general, we find that collaboration has positive effects. In Germany, subsidies for individual research do neither exhibit a significant impact on R&D nor on patenting, but the innovative performance could be improved by additional incentives for collaboration. For Finnish companies, public funding is an important source of finance for R&D. Without subsidies, recipients would show less R&D and patenting activity, whilst those firms not receiving subsidies would perform significantly better if they were publicly funded.

Observations of serotonin and FMRFamide‐like immunoreactivity in palp sensory structures and the anterior nervous system of spionid polychaetes
Authors: Forest David L. , Lindsay Sara M. 
Published: December 2007

AbstractEvidence suggests that ciliated sensory structures on the feeding palps of spionid polychaetes may function as chemoreceptors to modulate deposit‐feeding activity. To investigate the probable sensory nature of these ciliated cells, we used immunohistochemistry, epi‐fluorescence, and confocal laser scanning microscopy to label and image sensory cells, nerves, and their organization relative to the anterior central nervous system in several spionid polychaete species. Antibodies directed against acetylated αtubulin were used to label the nervous system and detail the innervation of palp sensory cells in all species. In addition, the distribution of serotonin (5‐HT) and FMRFamide‐like immunoreactivity was compared in the spionid polychaetes Dipolydora quadrilobata and Pygospio elegans. The distribution of serotonin immunoreactivity was also examined in the palps of Polydora cornuta and Streblospio benedicti. Serotonin immunoreactivity was concentrated in cells underlying the food groove of the palps, in the palp nerves, and in the cerebral ganglion. FMRFamide‐like immunoreactivity was associated with the cerebral ganglia, nuchal organs and palp nerves, and also with the perikarya of ciliated sensory cells on the palps. J.

Published: December 2007

AbstractPurposeTo develop and validate an objective technique for 3D segmentation of manganese‐enhanced MR images of the optic nerve/tract (ON) in adult rats to improve contrast‐to‐noise (CNR) calculations and use the technique to ascertain if manganese dipyridoxyl diphosphate (MnDPDP) gives sufficient Mn2+ enhancement compared to MnCl2 when used for functional imaging of the visual pathway.Materials and MethodsIntravitreous injection of the manganese‐releasing MR contrast agent MnDPDP (30 nmol Mn2+) was performed to trace the ON in adult rats (n = 4). A positive control group of rats (n = 5) received a standard preparation of MnCl2 (200 nmol Mn2+), while gadodiamide (1500 nmol Gd3+) was administered in negative control rats (n = 2). An objective technique for 3D segmentation of the enhanced ON was developed. CNR profiles along the ON were calculated by resampling the 3D image‐volume in 2D planes perpendicular to the Mn2+ enhanced ON in 0.2 mm steps, 4 mm along the segmented ON measured from the lamina cribrosa.ResultsThe ON was successfully segmented and CNR calculated accurately within 2 minutes in a representative 3D MR image volume. Intravitreal MnDPDP injection resulted in significant MRI contrast enhancement of the retina and ON after 12–24 hours similar to that of MnCl2 injection.Conclusion3D semiautomated image segmentation and the use of MnDPDP can improve in vivo axon tracing based on MRI. Mn2+ was found to be released from MnDPDP after intravitreal injection in sufficient amounts to obtain functional tracing of the adult rat primary visual pathway. J. Magn. Reson.

Appearance‐related residual injury, posttraumatic stress, and body image: Associations within a sample of female victims of intimate partner violence
Authors: Weaver Terri L. , Resnick Heidi S. , Kokoska Mimi S. , Etzel Julie C. 
Published: December 2007

AbstractOne third of women who experience intimate partner violence (IPV) receive some form of injury. After acute injuries have healed, a victim's physical appearance may be altered with residual changes including marks or scars. This study included 56 female victims of IPV (31 with appearance‐related residual injury and a comparison group of 25 with no appearance‐related residual injury) and examined the associations between violence‐related experiences, body image distress, and symptoms of posttraumatic stress disorder (PTSD). Appearance‐related residual injury status moderated the relationship between body image distress and symptoms of PTSD. In addition, within the appearance‐related residual injury group, body image distress emerged a unique predictor of PTSD explaining incremental variance beyond that explained by severity of psychological maltreatment.
Crystallization Kinetics of PEO and PE in Different Triblock Terpolymers: Effect of Microdomain Geometry and Confinement
Authors: Boschetti‐de‐Fierro Adriana , Lorenzo Arnaldo T. , Müller Alejandro J. , Schmalz Holger , Abetz Volker 
Published: December 2007

AbstractThe isothermal crystallization kinetics of PEO and PE blocks within various triblock terpolymers were studied by DSC. The effect of the geometry of the microdomains was analyzed by studying different compositions of PE‐b‐PS‐b‐PEO triblock terpolymers. The crystallization rate decreased for decreasing block content for both crystallizable blocks. The effect of the microdomain geometry, confinement or chain tethering on the crystallization of PEO was extensively studied by comparing pairs of triblock terpolymers with differences either in the nature (crystalline, glassy, amorphous) or in the location of the other blocks in the terpolymer.magnified image
The effects of the researcher's physical attractiveness and gender on mail survey response
Authors: Dommeyer Curt J. 
Published: December 2007

AbstractThis study examines how using a photo in the cover letter of a mail survey affects mail survey response. A 2 × 2 factorial design was used that manipulated the physical attractiveness and gender of the supposed researcher that was depicted in the cover letter photo. In addition, a control group was used that received a cover letter without a photo. The results revealed the following: (1) a photo of the survey researcher does not enhance the response rate to the survey; (2) in the case of an attractive male researcher, a photo may dampen the response rate; and (3) within the factorial design, the only variable to have an effect on the survey's response rate was the gender variable: Photos depicting female researchers produced a higher response rate than photos depicting male researchers. This study also illustrated that a crude pretest of the survey procedures with students can, in some areas, produce fairly accurate predictions of the results of a field experiment. © 2008 Wiley Periodicals, Inc.

AbstractA preceding article described the clinical features of Parkinson's disease dementia (PD‐D) and proposed clinical diagnostic criteria for “probable” and “possible” PD‐D. The main focus of this article is to operationalize the diagnosis of PD‐D and to propose pratical guidelines based on a two level process depending upon the clinical scenario and the expertise of the evaluator involved in the assessment. Level I is aimed primarily at the clinician with no particular expertise in neuropsychological methods, but who requires a simple, pragmatic set of tests that are not excessively time‐consuming. Level I can be used alone or in concert with Level II, which is more suitable when there is the need to specify the pattern and the severity on the dementia of PD‐D for clinical monitoring, research studies or pharmacological trials. Level II tests can also be proposed when the diagnosis of PD‐D remains uncertain or equivocal at the end of a Level I evaluation. Given the lack of evidence‐based standards for some tests when applied in this clinical context, we have tried to make practical and unambiguous recommendations, based upon the available literature and the collective experience of the Task Force. We accept, however, that further validation of certain tests and modifications in the recommended cut off values will be required through future studies. © 2007 Movement Disorder Society
