Distinguishing true from false memories in forensic contexts: Can phenomenology tell us what is real?
Authors: Marche Tammy A. , Brainerd C. J. , Reyna Valerie F. 
Published: September 2009

AbstractWe studied the extent to which subjective ratings of memory phenomenology discriminate true‐ and false‐memory responses, and whether degree of gist‐based processing influences false memory and phenomenology, in a classic forensic task, the Gudjonsson Suggestibility Scale (GSS). Participants heard a narrative of a robbery followed by suggestive questions about the content of the narrative. They were asked to rate the items they recognized as studied using the Memory Characteristics Questionnaire (MCQ). Consistent with studies of word lists, there were phenomenological differences between true and false memory responses: memory phenomenology was richer for true than for false memories, which supports opponent‐process accounts of false memory such as fuzzy‐trace theory. Thus, phenomenology is a useful means for differentiating experienced from non‐experienced events in forensic contexts. Copyright © 2009 John Wiley & Sons, Ltd.

Published: September 2009

AbstractThe structural and magnetic properties of ferromagnetic nanotubes fabricated by a low cost electrodeposition method are investigated. The fabrication of various elemental ferromagnetic materials are described, such as Fe, Co, and Ni, and ferromagnetic alloys, such as NiFe, CoPt, CoFeB, and CoCrPt nanotube arrays, in aluminum oxide templates and polycarbonate membranes with different diameters, wall thicknesses, and lengths. The structural, magnetic, and magnetization reversal properties of these nanotubes are investigated as a function of the geometrical parameters. The angular dependence of the coercivity indicates a transition from the curling to the coherent mode for the ferromagnetic nanotubes. The results show that nanotube fabrication allows the outer and inner diameter, length, and thickness of the nanotubes to be tuned systematically. The magnetization processes of ferromagnetic nanotubes are influenced by the wall thickness.

AbstractGreat interest in single‐walled carbon nanotubes (SWCNTs) derives from their remarkable electrical, thermal, optical, and mechanical properties together with their lower density, which promise extensive and unique applications. Much progress has been achieved in the fundamental and applied investigations of SWCNTs over the past decade. At the same time, many obstacles still remain, hampering further development in this field. To clarify the emerging problems and to provide a comprehensive understanding of the field, we review the recent progress of research on the synthesis, structure, and properties of SWCNTs, in particular the SWCNT non‐woven film, SWCNT rings, boron–nitrogen (B–N) co‐doped SWCNTs (BCN‐SWNTs), and individual SWCNTs. Some long‐standing problems and topics warranting further investigations in the near future are addressed.
CHM gene molecular analysis and X‐chromosome inactivation pattern determination in two families with choroideremia
Authors: Perez‐Cano Hector J. , Garnica‐hayashi Rosa E. , Zenteno Juan C. 
Published: September 2009

AbstractChoroideremia is an X‐linked recessive retinal dystrophy characterized by progressive loss of the photoreceptor, the retinal pigment epithelium, and the choriocapillaris layers which ultimately can result in blindness by the fifth decade of life. The disease is caused by mutations in the gene CHM, which encodes a protein involved in the regulation of intracellular vesicular traffic. Typically, hemizygous males are affected by the disease and female carriers are asymptomatic with only a diffuse mottled pattern of hyperpigmentation on funduscopy. Uncommon instances of fully affected females have been described previously and these cases are proposed to arise from an skewed Lyonization mechanism preferentially inactivating the X chromosome carrying the normal CHM allele. In this work, the clinical and molecular features of two Mexican families with choroideremia are described. A novel and a previously described CHM mutation were identified. X‐chromosome inactivation assays were performed in a total of 12 heterozygous carriers from the two families. In an affected female from family A, a random X‐inactivation pattern was demonstrated; on the other hand, in a female carrier from family B displaying a conspicuous pattern of pigment epithelium mottling at the peripheral retina, a skewed X‐inactivation pattern was found. However, the X‐chromosome preferentially inactivated in this female was the one carrying the mutated allele. Our results add to the genotypic spectrum in choroideremia and does not support a correlation between X‐inactivation status and abnormal retinal phenotype in heterozygous female carriers from these two families. © 2009 Wiley‐Liss, Inc.

AbstractWe report on two siblings with a severe neonatal form of spondylometaphyseal dysplasia (SMD). Similar cases have been reported in four publications. Analysis of pedigree data from the original and present families suggests an autosomal recessive mode of inheritance, although parental gonadal mosaicism is also possible. The similarities in the phenotype between our patients and spondyloepimetaphyseal dysplasia congenita (SEMDC) and spondyloepimetaphyseal dysplasia Strudwick (SEMDS) type, indicated that these patients could have a defect in the COL2A1 gene. Molecular analysis of genomic DNA of these patients excluded this gene. Another potential candidate gene PTHR1, was also analyzed in the selected regions and no mutation was found. This gene is probably causative in the Jansen type of SMD, which shares some phenotypic features with the siblings whom we documented. Our results indicate that a new candidate gene for the reported form of SMD should be sought. © 2009 Wiley‐Liss, Inc.

Published: September 2009

AbstractMastocytosis refers to a heterogeneous group of rare disorders characterized by an abnormal accumulation of mast cells in one or more organ systems. Cutaneous mastocytosis (CM) is the most frequent form in children and is characterized by hyperpigmented macules or papules symmetrically distributed over the trunk, and less so over the limbs, neck, and scalp. Two published articles have reported on unrelated girls presenting with mastocytosis, microcephaly, hearing loss, and hypotonia. Based on the original observation, this disorder was defined as CM with short stature, conductive hearing loss, and microtia (OMIM 248910). Here we report on a girl with similar manifestations who corroborates the existence of this rare disorder. CM, microcephaly, microtia, and/or hearing loss are the minimal diagnostic criteria. All the known patients were sporadic, but parental consanguinity in the first case argues for a possible autosomal‐recessive inheritance. © 2009 Wiley‐Liss, Inc.
Clinical variability of Waardenburg–Shah syndrome in patients with proximal 13q deletion syndrome including the endothelin‐B receptor locus
Authors: Tüysüz Beyhan , Collin Anna , Arapoğlu Müjde , Suyugül Nezir 
Published: September 2009

AbstractWaardenburg–Shah syndrome (Waardenburg syndrome type IV‐WS4) is an auditory‐pigmentary disorder that combines clinical features of pigmentary abnormalities of the skin, hair and irides, sensorineural hearing loss, and Hirschsprung disease (HSCR). Mutations in the endothelin‐B receptor (EDNRB) gene on 13q22 have been found to cause this syndrome. Mutations in both alleles cause the full phenotype, while heterozygous mutations cause isolated HSCR or HSCR with minor pigmentary anomalies and/or sensorineural deafness. We investigated the status of the EDNRB gene, by FISH analysis, in three patients with de novo proximal 13q deletions detected at cytogenetic analysis and examined the clinical variability of WS4 among these patients. Chromosome 13q was screened with locus specific FISH probes and breakpoints were determined at 13q22.1q31.3 in Patients 1 and 3, and at 13q21.1q31.3 in Patient 2. An EDNRB specific FISH probe was deleted in all three patients. All patients had common facial features seen in proximal 13q deletion syndrome and mild mental retardation. However, findings related to WS4 were variable; Patient 1 had hypopigmentation of the irides and HSCR, Patient 2 had prominent bicolored irides and mild bilateral hearing loss, and Patient 3 had only mild unilateral hearing loss. These data contribute new insights into the pathogenesis of WS4. © 2009 Wiley‐Liss, Inc.

AbstractThe skeleton is frequently affected in individuals with neurofibromatosis type 1, and some of these bone manifestations can result in significant morbidity. The natural history and pathogenesis of the skeletal abnormalities of this disorder are poorly understood and consequently therapeutic options for these manifestations are currently limited. The Children's Tumor Foundation convened an International Neurofibromatosis Type 1 Bone Abnormalities Consortium to address future directions for clinical trials in skeletal abnormalities associated with this disorder. This report reviews the clinical skeletal manifestations and available preclinical mouse models and summarizes key issues that present barriers to optimal clinical management of skeletal abnormalities in neurofibromatosis type 1. These concepts should help advance optimal clinical management of the skeletal abnormalities in this disease and address major difficulties encountered for the design of clinical trials. © 2009 Wiley‐Liss, Inc.
Detailed assessment of the ear in Cornelia de Lange syndrome: Comparison with a control sample using the new dysmorphology guidelines

Published: September 2009

AbstractThe literature abounds with reports of malformation syndromes in which human external ears are variously described as dysplastic, abnormal, large/small, low set, typical, or in some way unusual. Rarely is the ear well illustrated or described in meaningful detail. With few exceptions, such as Down syndrome, there is no real understanding of the degree to which ear morphology is affected in a specific syndrome. This paper describes a retrospective attempt to apply the recently published Morphological Definitions of the ear to compare a control sample of convenience with a group of patients with Cornelia de Lange syndrome (CdLS) (all six papers in this issue are available online, open access at http://www3.interscience.wiley.com/journal/121641055/issue). Although this study has a number of limitations, it demonstrates that the method can be successfully applied and is capable of producing data that can be subjected to statistical analysis. The ears of the patients with CdLS were significantly different from the controls over a number of descriptors, the most significant of which included more frequent apparent posterior rotation, a shorter more serpiginous antihelical stem and sharper antihelical to inferior crus angle, a shorter crus helix, a more V‐shaped incisura, and a smaller lobe. © 2009 Wiley‐Liss, Inc.
Preparation and characterization of injection‐homo‐polypropylene filled with nano‐CaCO3
Authors: Wang Wen‐Yi , Wang Guo‐Quan , Zeng Xiao‐Fei , Chen Jian‐Feng 
Published: September 2009

AbstractNano‐CaCO3/homo‐PP composites were prepared by melt‐blending using twin‐screw extruder. The results show that not only the impact property but also the bending modulus of the system have been evidently increased by adding nano‐CaCO3. The nano‐CaCO3 particles have been dispersed in the matrix in the nanometer scale which was investigated by means of transmission electron microscopy (TEM). The toughening mechanism of nano‐CaCO3, investigated by means of dynamical mechanical thermal analysis (DMTA) and scanning electron microscopy (SEM), lies on that the nano‐CaCO3 particles take an action of initiating and terminating crazing (silver streak), which can absorb more impact energy than the neat PP. At the same time, the nano‐CaCO3 particles, as the nuclear, decrease the crystal size of PP, the results of which were investigated by means of polarized optical microscope (POM). © 2009 Wiley Periodicals, Inc.

Thermoresponsive surface prepared by atom transfer radical polymerization directly from poly(vinylidene fluoride) for control of cell adhesion and detachment
Authors: Ke Zhenjiang , Dai Baihui , Li Liang , Yan Guoping , Zhou Dongshan 
Published: September 2009

AbstractThermoresponsive surface was prepared from commercial poly(vinylidene fluoride) (PVDF) films via surface‐initiated atom transfer radical polymerization. The direct initiation of the secondary fluorinated site of PVDF facilitated grafting of the N‐isopropylacrylamide (NIPAAm) monomer. The PVDF surfaces grafted with poly(N‐isopropylacrylamide) [P(NIPAAm)] were characterized by X‐ray photoelectron spectroscopy. Kinetics study revealed that the P(NIPAAm) chain growth from the PVDF surface was consistent with a “controlled” process. The temperature‐dependent swelling behavior of the surfaces in aqueous solution was studied by atomic force microscope. At 37°C [above the lower critical solution temperature (LCST, about 32°C) of NIPAAm], the seeded cells adhered and spread on the NIPAAm grafted PVDF surface. Below the LCST, the cells detached from the P(NIPAAm)‐grafted PVDF surface spontaneously. The thermoresponsive surfaces are potentially useful as stimuli‐responsive adhesion modifiers in the biomedical fields.© 2009 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
Controlling the structure of a porous polymer by coupling supercritical CO2 and single screw extrusion process

Published: September 2009

AbstractA study on the extrusion of Eudragit E100 was carried out using supercritical carbon dioxide (scCO2) as plasticizer and foaming agent. ScCO2 modifies the rheological properties of the material in the barrel of the extruder and acts as a blowing agent during the relaxation when flowing through the die. For experiments, a single‐screw extruder was modified to be able to inject scCO2 within the extruded material. The aim is to determine a correlation between operating conditions and foam structure. The effect of three parameters was studied: the temperature in the die and in the metering zone, the screw speed, and the volumetric flow rate of CO2. An increase in temperature enhances the expansion rate and the average pore diameter and appears to be the most significant parameter. The effect of CO2 concentration is significant at small concentrations only: the higher the CO2 concentration, the lower the pore density and the higher both the pore diameter and the expansion rate. The effect of the screw speed is tricky because a variation of this speed involves a decrease of CO2 weight ratio. This study shows that the structure of the extrudates does not evolve with a coupling of screw speed increase and a subsequent CO2 weight ratio decrease. © 2009 Wiley Periodicals, Inc.

Dynamic rheological behavior and morphology of poly(trimethylene terephthalate)/poly(ethylene octene) copolymer blends

Published: September 2009

AbstractThe dynamic rheology and morphology of poly(trimethylene terephthalate) and maleic anhydride grafted poly(ethylene octene) composites were investigated. A specific viscoelastic phenomenon, that is, a second plateau, appeared at low frequencies and exhibited a certain dependence on the content of elastomer particles and the temperature. This phenomenon was attributed to the formation of an aggregation structure of rubber particles. The analyses of the dynamic viscoelastic functions suggested that the heterogeneity of the composites was enhanced as the particle content or temperature increased. The microstructural observation by scanning electron microscopy confirmed that maleic anhydride could react with the end groups of poly(trimethylene terephthalate) to form a stable interfacial layer and result in a smaller dispersed‐phase particle size due to the reduced interface tension. © 2009 Wiley Periodicals, Inc.

Asymmetric bihomologous crosslinkers for bicomponent gels—The way to strongly increased elastic moduli
Authors: Demirgöz Döne , Navarro Rodrigo , Pérez Mónica , Reinecke Helmut , Gallardo Alberto 
Published: September 2009

Abstract2‐Hydroxyethylmethacrylate (HEMA) and acrylamide (AA) have been copolymerized via free radical mechanism, in the presence of 5 mol % of four different crosslinker systems, the symmetric ethylenglycoldimethacrylate (EGDMA), bisacrylamide (BIS), a mixture of EGDMA and BIS, and the asymmetric acrylamideethylenmethacrylate (METAA). The polymerizations have been monitored with a rheometer, exhibiting the gel obtained with the asymmetric METAA, an elastic modulus that is dramatically increased compared with those of the gels prepared with the other three crosslinker systems. A kinetic analysis using the terminal model has been used to build probabilistic surfaces that give information about how the crosslinker is incorporated into the network. This analysis shows a high dissimilarity between the reactions using the asymmetric and the mixture of symmetric crosslinkers, what has been correlated to the difference in modulus. © 2009 Wiley Periodicals, Inc.

Effect of ionizing irradiation and blending of natural rubber latex on polyvinylalcohol gelation by using chemical and freezing–thawing processes for use in the field of construction engineering
Authors: El‐Nahas H. H. , Heba R. A. , Magida M. M. 
Published: September 2009

AbstractThe aim of this work is to study the gelation behavior of polyvinylalcohol (PVA) and natural rubber latex (NRL) using two methods: The first was chemical gelation by adding sodium borate as a crosslinking to obtain a modeling clay gel able to draw easily under tension (using drum mill) or by using hand pressing. Irradiation was then applied at 2.5 Mrad to possess more crosslinking effect, where stable and rubbery‐gel shape in the dimension was obtained. The second method, where samples of liquid PVA were frozen and thawed for three consecutive cycles. The obtained gel was quite rubbery but completely soluble in hot water at 70°C. Irradiation was performed at 2.5 Mrad to produce a highly rubbery gel and resistant to boiled water. Also, blending of NRL with PVA induced a significant increase in gel‐elasticity and resistivity to boiled water. Factors affecting the properties of the prepared gel such as gel draw ability and gel strength were studied. The study was supported with thermal and scanning electron microscopy (SEM) to investigate the modification of PVA‐gel behavior through irradiation and blending with NRL processes. The results indicated that the PVA‐gel obtained by chemical method or blended with NRL through freezing–thawing gelation gave a superior ability for cement loading. © 2009 Wiley Periodicals, Inc.

Preparation of syndiotacticity‐rich high molecular weight poly(vinyl alcohol)/iodine polarizing film with high water resistance
Authors: Han Man Ho , Lyoo Won Seok 
Published: September 2009

AbstractTo enhance durability of poly(vinyl alcohol) (PVA)/iodine polarizing film under humid and warm atmospheres and to identify the effects of syndiotacticity on the polarizing efficiency (PE) and durability of PVA/iodine complex film, we prepared three high molecular weight (PVA)s with similar number‐average degree of polymerization (Pn) of 4000 and with different syndiotactic diad (s‐diad) contents of 53, 56, and 59%, respectively. It was found that syndiotacticity of PVA had a significant influence on the durability of PVA/iodine complex film in warm and humidity conditions (relative humidity of 80% and temperature of 50°C). That is, both desorption of iodine in PVA/iodine film and transmittance of film decreased with increasing syndiotacticity of PVA. In the case of PE, the values of over 99% were obtained at each optimum conditions. The change of PE (durability) of PVA/iodine complex films having Pn of 4000 and s‐diad contents of 56 and 59%, respectively, in warm and humidity conditions was almost zero, whereas those of PVA/iodine film with s‐diad content of 53% and with (Pn)s of 1700 and 4000 were about 60% and 50%, respectively, under same conditions. © 2009 Wiley Periodicals, Inc.
