Risk factors for the late‐onset psychoses: a systematic review of cohort studies
Authors: Brunelle Sarah , Cole Martin G. , Elie Michel 
Published: April 2011

BackgroundPsychoses with onset in late adulthood are challenging. Identifying those older patients at risk would be clinically important and would have research implications.MethodsA computer search was performed to identify all cohort studies of risk factor(s) for psychotic symptoms or disorders with onset at 40 years or older. Experts were contacted and bibliographies were screened for additional references. Validity of located studies was assessed according to evidence‐based medicine criteria for risk factors studies. Data were extracted and tabulated for qualitative and quantitative analyses.ResultsTwelve articles were retrieved, corresponding to 11 studies of 32 potential risk factors. In the qualitative analysis, only the history of psychotic symptoms, cognitive problems, poor health status, visual impairment, and negative life events appeared to be significant risk factors of late‐onset psychosis. Older age, female gender, and hearing impairment were not associated with psychosis in older patients. Quantitative analysis was feasible with only one item, female gender, and confirmed the lack of associated risk with late‐onset psychosis.ConclusionsDespite the methodological limitations of the studies included in this review, there is some evidence from cohort studies that history of psychotic symptoms, cognitive problems, poor physical health, visual impairment, and negative life events are risk factors for late‐onset psychosis. More long‐term follow‐up studies are needed to confirm these findings. Copyright © 2011 John Wiley & Sons, Ltd.

Published: April 2011

ObjectivesTo compare initial diagnostic hypotheses made by Allied Health Professionals (AHP) (mental health nurses, occupational therapists and social workers) with subsequent formal multidisciplinary formulation based upon the full possession of investigations, neuropsychological tests and brain imaging. Design Prospective analysis.DesignProspective analysis.SettingHome‐based assessments, secondary care based multidisciplinary memory clinic.Participants90 consecutive referrals over a 3‐month period.ResultsFifty eight patients (64.4%) were diagnosed by the multi‐disciplinary team as having a dementia. Twenty (34%) were classified as Alzheimer's disease, 28 (49%) of mixed sub‐type and 9 (16%) of vascular origin. Together, AHP's were able to detect dementia with 91% accuracy (Kappa 0.81) sensitivity was 0.88 and specificity 0.97. The diagnostic accuracy for each professional group ranged from 88% to 93% (Kappa 74–90%).ConclusionsIn this study, structured initial assessment by AHP's working in a Memory Assessment Service was shown to be an accurate method of determining a diagnosis of cognitive impairment, when compared with formal MDT judgment. It is suggested that such distributed responsibility affords a viable option for the future detection of early dementia. Copyright © 2011 John Wiley & Sons, Ltd.
Respiratory morphology of the Abedus herberti Hidalgo egg chorion (Hemiptera: Belostomatidae)
Authors: Goforth Christine L. , Smith Robert L. 
Published: April 2011

AbstractAlthough giant water bugs (Hemiptera: Belostomatidae) are large, aquatic insects known for their obligate paternal egg brooding behaviors, little research has focused on the structure of their eggs. The respiratory requirements of developing embryos likely created selection for brooding, so a thorough understanding of the respiratory morphology of belostomatid eggs could help explain how brooding behaviors facilitate embryonic gas exchange. This study used scanning electron microscopy to document the respiratory microstructure of the eggs of Abedus herberti, a back brooding giant water bug. The exochorion is similar to that of other belostomatids in texture and organization except that the respiratory region is confined to the uppermost quarter of the egg. This is the area exposed to the atmosphere by encumbered males. A plastron network made up of densely packed vertical projections demarcates the boundary between the respiratory and nonrespiratory regions of the chorion. The internal chorion is composed of alternate air‐filled and denser layers that likely facilitate the movement of oxygen from the aeropyles at the top of the eggs to the developing embryonic tissues.

Published: April 2011

AbstractThe dielectric property of a nanoparticle‐supporting film has recently garnered attention in the fabrication of plasmonic surfaces. A few studies have shown that the localized surface plasmon resonance (LSPR), and hence surface‐enhanced Raman scattering (SERS), strongly depends on the substrate refractive index. In order to create higher efficiency SERS‐active surfaces, it is therefore necessary to consider the substrate property along with nanoparticle morphology. However, due to certain limitations of conventional lithography, it is often not feasible to create well‐defined plasmonic nanoarrays on a substrate of interest. Here, an additive nanofabrication technique, i.e., nanotransfer printing (nTP), is implemented to integrate electron beam lithography (EBL) defined high‐aspect‐ratio nanofeatures on a variety of SERS‐supporting surfaces. With the aid of suitable surface chemistries, a wide range of plasmonic particles were successfully integrated on surfaces of three physically and chemically distinct dielectric materials, namely, polydimethyl siloxane (PDMS), SU‐8 photoresist, and glass surfaces, using silicon‐based relief pillars. These nTP‐created metal nanoparticles strongly amplify the Raman signal and complement the selection of suitable substrates for better SERS enhancement. Our experimental observations are also supported by theoretical calculations. The implementation of nTP to stamp out metal nanoparticles on a multitude conventional/unconventional substrates has novel applications in designing in‐built plasmonic microanalytical devices for SERS sensing and other related photonic studies.

Published: April 2011

AbstractBackground and ObjectivesThe colon is a rare location for gastrointestinal non‐Hodgkin's lymphoma. We retrospectively analyzed the demographic data of patients with colonic lymphoma and the possible prognostic factors of the disease.MethodsWe studied data obtained from 6,944 patients and performed a retrospective review of patients with primary colonic lymphoma (PCL) by using a pathology registry database. We employed well‐established and accepted diagnostic criteria and clinical staging method.ResultsTwenty‐nine patients (19 men; 10 women) were diagnosed with PCL. The cecum was the most common tumor location (14/29 patients), and 17 cases (17/29) showed diffuse large–B‐cell lymphomas. Four patients died of sepsis within 30 days of an emergency surgery for perforation of intestine. Two‐thirds of the patients were in the early disease stages (stages I and II). The overall 5‐year survival rate was 47.3%. Disease stage was not a prognostic factor for survival. The overall 5‐year survival rate in patients treated with surgery followed by chemotherapy was statistically significant as compared to that in the patients treated with chemotherapy alone.ConclusionPCL is a rare malignancy of the gastrointestinal tract, and surgical resection should be considered a part of the standard treatment to achieve a better outcome.

LDPE/EVA/PCR/MWNT nanocomposites: Radiation crosslinking and physicomechanical characteristics
Authors: Dubey Kumar Abhinav , Bhardwaj Yatender K. , Chaudhari Chandrashekhar V. , Sabharwal Sunil 
Published: April 2011

AbstractNanocomposites of low‐density polyethylene (LDPE)/ethyl vinyl acetate (EVA)/poly(chloroprene) rubber (PCR) blends and multiple walled carbon nanotubes (MWNT) were prepared in different compositions by melt mixing. The nanocomposites were subjected to different radiation doses and efficacy of radiation crosslinking and physic‐mechanical characteristics were analyzed in detail. Gel content and crosslinking density increased with dose and with the MWNT fraction in the nanocomposites. The elastic modulus of the nanocomposite increased, while elongation at break exhibited downward trend with radiation dose. Micromechanical modeling of elastic modulus indicated presence of agglomeration in the matrix. Bulk density of the nanocomposites increased with the addition of MWNT while the melt flow index of the nanocomposites decreased sharply. DSC, XRD and TGA investigations revealed the peculiarity of the MWNT led nucleation in LDPE/EVA/PCR/MWNT nanocomposites. POLYM. COMPOS., 2011. © 2011 Society of Plastics Engineers
PTCR characteristics of polycarbonate/nickel‐coated graphite‐based conducting polymeric composites in presence of poly(caprolactone)
Authors: Kar Prativa , Khatua B.B. 
Published: April 2011

AbstractThe effect of poly(caprolactone) (PCL) on the positive temperature coefficient of resistivity characteristics of polycarbonate (PC)/nickel (Ni)‐coated graphite (40 wt%) composites was investigated. The PTC trip temperature of PC/Ni‐coated graphite composites appeared at 155°C. On addition of PCL to PC/Ni‐coated graphite composites, the PTC trip temperature reduced to 125°C, well below the Tg of the PC (∼147°C), as well as the PC/PCL (∼136°C) blend. It is noteworthy that the observed PTC effect for PC/PCL (8 wt%)/Ni‐coated graphite (40 wt%) composites is highly reproducible during many heating cycles. The coefficient of thermal expansion (CTE) of PC was increased in presence of PCL. Thus, the mismatch in CTE of the PC and Ni‐coated graphite at a temperature well below the Tg of PC was enough to disrupt the continuous network structure that increased the resistivity of the composites. Storage modulus of PC/PCL/Ni‐coated graphite composites was higher than PC/Ni‐coated graphite composites. POLYM. COMPOS., 2011. © 2011 Society of Plastics Engineers

Published: April 2011

AbstractThe transgenic adenocarcinoma of mouse prostate (TRAMP) is the most widely used transgenic model for prostate cancer chemoprevention studies. Although two lobe‐specific lineages of carcinogenesis have been described, the molecular mechanisms are still poorly defined. Here, we concurrently profiled the proteome of dorsal‐lateral (DLP) and ventral (VP) prostate lobes of both TRAMP and littermate WT C57BL/6 mice of 18 wk by 2‐D LC‐MALDI‐TOF/TOF with iTRAQ labeling. A total of 483 and 748 proteins were identified at critical false discovery rates of 1 and 5%. In WT mice, 84 proteins were found to have different expression levels between DLP and VP. In TRAMP mice, 118 proteins significantly changed in DLP and/or VP during TRAMP carcinogenesis. Among them, 55 and 36 proteins were uniquely changed in DLP or VP lobe, respectively, and 27 proteins in both DLP and LP lobe. Ingenuity Pathway Analysis was able to segregate proteins changed in two lobes into different pathway networks. In addition to serving as reference for prostate proteomic profiles, our data suggest that different sets of proteins are involved in the carcinogenesis in DLP versus VP in the TRAMP model.

AbstractThe BIAMS conference series was inaugurated in 1988 in Paris and followed by conferences in France, Italy, Spain, Germany, and Russia. BIAMS 2010, held in Halle (Germany) from July 4 to 8, 2010, is the direct follower of the conferences of 2006 held in St. Petersburg (Russia) and 2008 in Toledo (Spain). The organizers of the Halle meeting were the Max‐Planck‐Institut für Mikrostrukturphysik Halle and the Martin‐Luther‐Universität Halle‐Wittenberg.The 2010 meeting put main emphasis on principal experimental and theoretical aspects of the assessment of defects and nano‐ and microstructures in semiconductors by beam injection and related methods. The workshop was a forum for interaction between physicists, materials scientists and technologists working in this field. The following main topics were covered: electron beam and optical characterization methods, scanning probe microscopy, and ion beam techniques. The application of these techniques were related to point and extended defects in semiconductors, to heterostructures, quantum wells, interfaces, and nanowires. A special topic was the investigation of photovoltaic materials and devices.This issue of physica status solidi contains papers presented as invited talks and oral or poster contributions at BIAMS 2010 in Halle. We would like to thank all participants for their contributions.The meeting was supported by the Deutsche Forschungsgemeinschaft and many companies from the solar business (© 2011 WILEY‐VCH Verlag GmbH & Co.

Published: April 2011

AbstractMono‐varietal extra virgin olive oils were micro‐extracted from drupes that were selectively collected from 28 trees distributed in five different Southern Italian Apulian areas. Nuclear Magnetic Resonance (NMR) profiles of these oil samples were correlated to the genetic (young green material) and soil (samples collected within the foliage projection) data of the tree of origin. Genetic analysis, performed on the samples using SSRs (Simple Sequence Repeats) by 9 microsatellite loci, confirmed the specific cultivar assignment (among Cima di Mola, Coratina, Ogliarola, and Oliva Rossa cultivars). Chemometric methods applied to 1H‐NMR spectroscopic data were used for cultivar and geographical origin discrimination of the studied extra virgin olive oils. Linear Discriminant Analysis (LDA) afforded a high reliability degree for discriminating cultivars (almost 90% of prediction ability), and a good assigning ability for the geographical origin (Ogliarola and Coratina samples used as subsets). Soil analyses were performed for each tree. Regression analysis was applied to soil composition in order to correlate available nutrients and total metals with the content of fatty acids and minor components present in monovarietal extra virgin olive oils. In the case of oleic and linoleic fatty acids, and for some terpenes, B, Cr, Mn, Zn were found to give significant correlations. Zn and Mn were the most significant trace elements for all the correlations found (p < 0.01). The results obtained (genetic, spectroscopic and soil analyses) are discussed as a multidisciplinary approach for setting up a strategy for a cultivar and/or geographic origin certification committed database construction.

The Drama of Colonialism: National Identity and the Construction of theIndian/Otherin Early-19th-Century American Plays
Authors: Detsi-Diamanti Zoe 
Published: April 2011

This essay offers insights into the American nation's persistent denial and deep-seated fears of its own inextricably multicultural identity at the time of the American Revolution and the first half of the 19th century. American imperialism, and perhaps this is true of all imperialisms, was founded upon a stable hierarchical relationship between “civilized” and “savage.” Rhetorically, indigenous tribespeople seem to have fitted Frantz Fanon's description of “the realotherwhom the white man perceived on the level of the body image, absolutely as the non-self – that is, the unidentifiable, the unassimilable” (161 n.). On the one hand, the imperialistic drive across the continent in the name of Manifest Destiny, and, on the other, the nation's wishful thinking to constrict the boundaries ofAmerican identityinto a fixed, pure and homogeneous body of values, unleashed the forces of cultural exclusion. In this essay, I try to show how the dominant white society's narcissistic view of itself as an empire operating under the auspices of Divine Providence actually resulted in a series of political acts of nativist violence. I have deliberately chosen to focus on the dramatic literature of the 19th century as a still largely unexplored territory of American literature in order to trace and expose the contradictory representations of the Native American as both historically absent and integral to the nation's conception of its own identity as the “center.”The palefaces are all around us, and they tread in blood. The blaze of our burning wigwams flashes awfully in the darkness of their path. We are destroyed — not vanquished; we are no more, yet we are forever.
