Alternated sport competition and athietic auto-illusion of competence for adolescents in school failure
The purpose of this study is to measure the effects of altemated sport competitions (Segregated and integrated) on perceived competence for adolescents in school failure presenting an intellectual disability (ID) or conduct behavior (CB) placed in French specialized establishment. Compared to student schooled in an ordinary sector, adolescents with ID and CB present an inability to appreciate their possibility and to recognize their weakness. This inability can translate a physical auto-illusion of competence. The central hypothesis of this work suggests that the alternated sport compétitions are going to encourage the decristallisation of the physical auto-illusion of competence of the adolescents with ID and CB. The Self Perception Profile of Harter (1985) has been administrated seven times in seven months to two groups of eight ID adolescents and two groups of eight CB adolescents practicing basketball and cross-country, as well as to four control groups (sedentary and physical education). The results show a stability of the « physical » perceived competence and « general self-worth » on a length of seven months. The alternated competitions play a damaging role to the construction of a realist perceived competence. It seems therefore that in the long term, only the practice of integrated competitions can contribute to reduce the physical auto-illusion of competence of adolescents with ID and CB.

Summary
Aim: Myocardial perfusion scintigraphy (MPS) is one of the widely used tools to follow developing radiation-induced heart disease (RIHD). But the clinical significance of MPS defects has not been fully understood. We have investigated the biodistribution alterations related to perfusion defects following radiotherapy (RT) and showed coexisting morphologic changes. Animals, methods: A total of 18 Wistar rats were divided into three groups (1 control and 2 irradiated groups). A single cardiac 20 Gy radiation dose was used to induce long term cardiac defects. Biodistribution studies with technetium (99mTc) sestamibi and histological evaluations were performed 4 and 6 months after irradiation. The percent radioactivity (%ID/g) was calculated for each heart. For determination of the myocardial damage, positive apoptotic cardiomyocytes, myocardial cell degeneration, myocardial fibrosis, vascular damage and ultrastructural structures were evaluated. Results: Six months after treatment, a significant drop of myocardial uptake was observed (p < 0.05). Irradiation- induced apoptosis rose within the first 4 months after radiation treatment and were stayed elevated until the end of the observation period (p < 0.05). Also, the irradiation has induced myocardial degeneration, perivascular and interstitial fibrosis in the heart at the end of six and four months (p < 0.01). The severity and extent of myocardial injury has became more evident at the end of six month (p < 0.05). At ultrastructural level, prominent changes have been observed in the capillary endothelial and myocardial cells. Conclusion: Our findings suggest that the reduced rest myocardial perfusion, occuring months after the radiation, indicates a serious myocard tissue damage which is characterized by myocardial degeneration and fibrosis.

Published: October 2010

AbstractPseudomyxoma peritonei is a poorly understood and uncommon tumor that is known for its production of mucin in the abdominal cavity and mucinous implants, diffusely involving the peritoneal surfaces. A 60-year-old female presented to us with post-op complaints of diffuse abdominal pain and distension. On work-up, she was diagnosed as a case of Pseudomyxoma peritonei (with residual disease). She received chemotherapy in the form of oral capecitabine for residual disease. She was totally asymptomatic till the last follow-up. This case is being reported on account of its rarity and to emphasize a simple alternative treatment option as compared to the standard one.

AbstractMesothelial cell inclusions in lymph nodes are of rare occurrence and can be mistaken as metastatic adenocarcinomas, mesothelioma or sinus histiocytosis. These are usually found in mediastinal and abdominal lymph nodes and are associated with effusions. We report a case of benign mesothelial cell inclusions in cervical lymph nodes, which was associated with chylous effusion, and immunohistochemistry revealed unusual weak cytoplasmic epithelial membrane antigen positivity in the cells.

An Energy Regularization for Cauchy Problems of Laplace Equation in Annulus Domain
Authors: Han Houde , Ling Leevan , Takeuchi Tomoya 
Published: October 2010

AbstractDetecting corrosion by electrical field can be modeled by a Cauchy problem of Laplace equation in annulus domain under the assumption that the thickness of the pipe is relatively small compared with the radius of the pipe. The interior surface of the pipe is inaccessible and the nondestructive detection is solely based on measurements from the outer layer. The Cauchy problem for an elliptic equation is a typical ill-posed problem whose solution does not depend continuously on the boundary data. In this work, we assume that the measurements are available on the whole outer boundary on an annulus domain. By imposing reasonable assumptions, the theoretical goal here is to derive the stabilities of the Cauchy solutions and an energy regularization method. Relationship between the proposed energy regularization method and the Tikhonov regularization with Morozov principle is also given. A novel numerical algorithm is proposed and numerical examples are given.
Efficient Dual Algorithms for Image Segmentation Using TV-Allen-Cahn Type Models
Authors: Wang Li-Lian , Gu Ying 
Published: October 2010

AbstractVariational image segmentation based on the Mumford and Shah model [31], together with implementation by the piecewise constant level-set method (PCLSM) [26], leads to fully nonlinear Total Variation (TV)-Allen-Cahn equations. The commonly-used numerical approaches usually suffer from the difficulties not only with the non-differentiability of the TV-term, but also with directly evolving the discontinuous piecewise constant-structured solutions. In this paper, we propose efficient dual algorithms to overcome these drawbacks. The use of a splitting-penalty method results in TV-Allen-Cahn type models associated with different “double-well” potentials, which allow for the implementation of the dual algorithm of Chambolle [8]. Moreover, we present a new dual algorithm based on an edge-featured penalty of the dual variable, which only requires to solve a vectorial Allen-Cahn type equation with linear ∇(div)-diffusion rather than fully nonlinear diffusion in the Chambolle’s approach. Consequently, more efficient numerical algorithms such as time-splitting method and Fast Fourier Transform (FFT) can be implemented. Various numerical tests show that two dual algorithms are much faster and more stable than the primal gradient descent approach, and the new dual algorithm is at least as efficient as the Chambolle’s algorithm but is more accurate. We demonstrate that the new method also provides a viable alternative for image restoration.

ABSTRACTObjectives: During the 2009 influenza A (H1N1) pandemic, Argentina's Hospital Nacional Profesor Alejandro Posadas, a referral center in the capital province of Buenos Aires, treated a large urban patient population. Beginning in April, after severe influenza had been reported in North America but before any suspected cases of H1N1 had been reported in Argentina, the authors formed a pandemic planning committee to direct our hospital's response. An important strategy of the management team was to create a single daily monitoring tool that could integrate multiple information sources. We describe our pandemic planning strategy so that it may serve as a template for other hospitals.Methods: We describe our integrated data management system and the indicators it measured. We also describe the iterative process used to develop these tools and the current versions we use in surveillance for possible new waves of pandemic influenza.Results: We present 3 examples of strategic decision making applied to data from our integrated information system. Daily pandemic surveillance data motivated the planning committee to reallocate hospital resources to care for patients during the peak pandemic period.Conclusions: This report illustrates the importance of pandemic planning and advanced integrated information tools for management of a health care facility during a pandemic.(Disaster Med Public Health Preparedness. 2010;4:207-212)
Spherical and Anisotropic Silver Nanomaterials in Medical Diagnosis
Authors: Zhao Yiping , Tripp Ralph A. 
Published: October 2010

Abstract
Silver‐based nanostructures have been widely used for biosensors and medical diagnostics due to their unique optical properties. In this chapter, we review the fundamentals of different novel diagnostics techniques, such as surface plasmon resonance, localized surface plasmon resonance, surface‐enhanced Raman spectroscopy, metal‐enhanced florescence and surface‐enhanced infrared absorbance spectroscopy, based on the unique plasmonic properties of silver nanostructures. The general methodology to synthesize and fabricate different silver nanostructures is also reviewed. Surface‐enhanced Raman spectroscopy has been used as an example to show the potential of Ag nanoparticle‐based diagnostic techniques in applications such as drug identification, biomarker tracing, DNA and RNA differentiation, virus and bacterial detection. The demonstrated Ag nanostructure‐based optical sensing techniques have not only high efficiency and sensitivity but also relatively simple equipment requirements and are economic – features which offer great potential for use in practical diagnostics.

Abstract

Silver nanoparticles are widely used products developed by current nanotechnology. Health and environmental risks are major obstacles for making nanotechnology more accessible to consumers and potential users. Although a considerable body of
in vitro
data on silver nanomaterials indicates the potential for adverse effects, the
in vivo
data are somewhat contradictory. A lack of human or environmental exposure data makes the health and environmental impact evaluation for silver nanomaterials more difficult.

Published: October 2010

AbstractThe ability to tailor the shapes and sizes of inorganic nanostructures is critical for modern materials chemistry, because the intrinsic properties of most nanostructures are strongly dependent on their shapes and sizes, which can be further useful for various applications. This chapter provides an overview of the various synthesis methods of spherical and anisotropic noble metal nanomaterials. The shapes of resultant nanostructures can be controlled by manipulating different parameters, such as the crystallinity of seeds and the growth rates of different crystallographic facets. In this chapter, we discuss a number of useful parameters that can be tuned to control the formation of anisotropic silver and gold nanostructures with a specific shape in a solution‐phase synthesis, using chemical and biological methods. A brief description of various synthesis methods and the characterization of the metal nanoparticles with a special emphasis on X‐ray absorption measurements have been provided in order to understand the mechanistic aspects of crystal growth. Using the synthesis methods described herein, a variety of well‐defined anisotropic shapes of silver and gold nanoparticles can be achieved and these methodologies can be directly extended to other metals.

Abstract
In this chapter we review the current state of research on symmetric and asymmetric silica nanomaterials, or nanosilica, in terms of their synthesis, characterization and applications. Both, catalytically and noncatalytically grown nanosilica are discussed, and several types of application for these nanomaterials are described. For asymmetric nanosilica, the focus is on helical nanosilica such as silica nanocoils and other helical nanosilica, whereas for symmetric silica nanomaterials the discussion covers more general forms of nanosilica, including nanoparticles, mesoporous nanomaterials and silica nanotubes.

AbstractThe ability to integrate metal nanoparticles into biological systems has had a major impact in biology and biomedicine. The development of nanobased biosensors has increased tremendously over the past few years, as demonstrated by the large number of scientific publications in this area. In this chapter we discuss recent efforts in the development of a nanomaterials surface energy transfer (NSET) probe for sensing biomolecules. Such a probe can improve the analytical figures of merit, such as detection limits, sensitivity, selectivity, and dynamic range, relative to currently available commercial systems.

Published: October 2010

AbstractD‐bifunctional protein deficiency (DBPD) is an autosomal recessive disease caused by a defect in peroxisomal β‐oxidation. The majority of patients suffer from a severe neurological disease with neonatal hypotonia and seizures and die within the first 2 years of life. Few patients show milder clinical phenotypes with prolonged survival. The diagnosis relies on the clinical presentation, measurement of peroxisomal markers, including very long chain fatty acids (VLCFA) in plasma, followed by enzymatic studies in fibroblasts and genetic testing. Diagnosis can be difficult to establish in milder cases, especially if VLCFA concentration in plasma is not or only mildly elevated. We report on siblings in which initial measurement of plasma VLCFA did not indicate a peroxisomal disease. Nevertheless, cMRI showed a pattern typical for an inborn peroxisomal disease with cerebral and cerebellar leukencephalopathy, perisylvic polymicrogyria, and frontoparietal pachygyria. Repeated measurements of peroxisomal metabolites in plasma prompted by the cMRI findings showed values in the upper normal or mildly elevated range and led to further diagnostic steps. The diagnosis of a type III DBPD with a missense mutation (T15A) in the HSD17B4 gene, coding for D‐bifunctional protein (DBP), could be established. We conclude that a typical “peroxisomal pattern” in cMRI including cerebral and cerebellar leukencephalopathy, perisylvic polymicrogyria and pachygyria is a valuable clue to the diagnosis of DBPD, especially in cases with no or only very mild abnormalities in plasma. © 2010 Wiley‐Liss, Inc.
Synthesis and properties of waterborne poly(urethane urea)s containing polydimethylsiloxane
Authors: Lee Young‐Hee , Kim Eun‐Ji , Kim Han‐Do 
Published: October 2010

AbstractTo obtain flexible waterborne poly(urethane urea) (WBPU) coatings with functionalities such as shape recovery and water resistance, we synthesized a series of WBPUs by a prepolymer mixing process from hexamethylene diisocyanate, polyol, 2,2‐bis(hydroxymethyl) propionic acid, ethylenediamine, and triethylamine with polyol blends [hydroxyl‐terminated polydimethylsiloxane (PDMS) with a number‐average molecular weight of ≈ 550 and poly(tetramethylene oxide) glycol (PTMG) with a number‐average molecular weight of 650] of different molar ratios. The effects of the PDMS content in PDMS/PTMG on the dynamic thermal and mechanical properties, hardness, tensile properties, water resistance (water absorption, contact angle, and surface energy), and shape‐memory properties of WBPU films were investigated. As the molar percentage of PDMS in WBPUs increased, the storage modulus, tensile strength and modulus, elongation at break, hardness, and shape‐retention rate (30–15%) decreased; however, the water resistance and shape‐recovery rate (80–90%) increased. © 2010 Wiley Periodicals, Inc.

Novel whey protein‐based aqueous polymer‐isocyanate adhesive for glulam
Authors: Gao Zhenhua , Wang Wenbo , Zhao Zongyan , Guo Mingruo 
Published: October 2010

AbstractWhey, a by‐product of cheese making, contains whey proteins, lactose, vitamins, and minerals. Whey and whey proteins are still not fully used. In this study, whey protein‐based aqueous polymer‐isocyanate (API) adhesives were developed and characterized by bond test, Fourier transform infrared (FTIR) spectroscopy, and scanning electron microscope (SEM) for bond strength, chemical structures, and morphology. The optimized whey protein‐based API adhesive for Glulam had a 28‐h boiling‐dry‐boiling wet strength of 6.81 MPa and a dry strength of 14.34 MPa. Results indicated that the addition of polyvinyl acetate emulsion can prolong the work life of the API adhesive. Addition of crosslinker polymeric methylene bisphenyl diisocyanate (P‐MDI) not only increased the cohesive strength of the cured adhesive by crosslinking whey proteins but also resulted in strong chemical bonds via urethane linkage in wood bondlines. Addition of polyvinyl alcohol (PVA) further increased the crosslinking density of the cured adhesive due to its capability of crosslinking whey proteins through the reaction with P‐MDI. Nanoscale CaCO3 powder (3.5 wt %) as filler significantly improved bond strength due to its mechanical interlock with the polymers in the adhesive. SEM examinations confirmed that both PVA and nanoscale CaCO3 improved the compatibilities of the components in the optimized whey protein‐based API adhesive. FTIR results revealed that P‐MDI reacts mainly with the residual amino groups rather than the hydroxyl groups of whey proteins. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
