AbstractThe use of autologous fat grafting is ideal in breast reconstruction. However, published data on long-term outcomes and instrumental results of fat grafting to the breast are lacking. The purpose of this study was to review the authors' experience of fat grafting, evaluating the effects related to the use of enhanced stromal vascular fraction (e-SVF) and fat grafting with platelet-rich plasma (PRP) in the maintenance of fat volume in breast reconstruction, comparing the results with a control group. Twenty-three patients aged 19–60 years affected by breast soft tissue defects were analyzed at the Plastic and Reconstructive Department of the University of Rome Tor Vergata. Ten patients were treated with SVF-enhanced autologous fat grafts, and 13 patients were treated with fat grafting + platelet-rich plasma. The patients in the control group (n = 10) were treated with centrifuged fat grafting injection according to Coleman's procedure. The patients treated with SVF-enhanced autologous fat grafts showed a 63% maintenance of the contour restoring and of three-dimensional volume after 1 year compared with the patients of the control group treated with centrifuged fat graft, who showed a 39% maintenance. In those patients who were treated with fat grafting and PRP, we observed a 69% maintenance of contour restoring and of three-dimensional volume after 1 year. As reported, the use of either e-SVF or PRP mixed with fat grafting produced an improvement in maintenance of breast volume in patients affected by breast soft tissue defect.
Adaptive prediction and control of discrete‐time Takagi–Sugeno fuzzy systems
Authors: Qi Ruiyun , Tao Gang , Tan Chang , Yao Xuelian 
Published: May 2012

SUMMARYThis paper derives a new prediction model of the global discrete‐time input‐output multiple‐delay Takagi–Sugeno (T‐S) fuzzy systems with multiple delays and employs it for adaptive fuzzy control in the presence of system parameter uncertainties. On the basis of a model‐based approach, a new system parametrization and adaptive control scheme are developed with detailed design procedure and complete stability analysis. The derived new fuzzy prediction model involves not only the current values of the membership functions but also their past values, expanding its capacity of approximating dynamic systems. A stable adaptive law is developed on the basis of an error model resulting from a new augmented parametric model for which a signal bounding property is also proved, crucial for closed‐loop system stability. An illustrative example is presented to demonstrate the studied new concepts and to verify the desired performance of the new types of adaptive fuzzy control systems.

Novel Signal‐Amplifying Fluorescent Nanofibers for Naked‐Eye‐Based Ultrasensitive Detection of Buried Explosives and Explosive Vapors
Authors: Wang Ying , La Anthony , Ding Yu , Liu Yixin , Lei Yu 
Published: May 2012

AbstractA novel electrospun fluorescent nanofiberous membrane with a function like “molecular wires” was developed via electrospinning for the detection of ultra‐trace nitro explosive vapors and buried explosives by naked eye under UV excitation. The high binding affinity between the electron‐deficient nitro explosives and the sensing film results in a rapid, dramatic quenching in its fluorescence emission. A wide spectrum of nitro explosives, in particular, TNT, Tetryl, RDX, PETN and HMX could be “visually” detected at their sub‐equilibrium vapors (less than 10 ppb, 74 ppt, 5 ppt, 7 ppt and 0.1 ppt, respectively) released from 1 ng explosives residues. Such outstanding sensing performance could be attributed to the proposed “sandwich‐like” conformation between pyrene and phenyl pendants of PS which may allow efficient long‐range energy migration similar to “molecular wire”, thus achieving amplified fluorescence quenching. Its application for the detection of buried explosives in soil by naked eye was also demonstrated, indicating its potential application for landmine mapping. To the best of our knowledge, this is the first report about the detection of buried explosives without the use of any advanced analytical instrumentation.
A Review of Mechanical and Electromechanical Properties of Piezoelectric Nanowires
Authors: Espinosa Horacio D. , Bernal Rodrigo A. , Minary‐Jolandan Majid 
Published: May 2012

AbstractPiezoelectric nanowires are promising building blocks in nanoelectronic, sensing, actuation and nanogenerator systems. In spite of great progress in synthesis methods, quantitative mechanical and electromechanical characterization of these nanostructures is still limited. In this article, the state‐of‐the art in experimental and computational studies of mechanical and electromechanical properties of piezoelectric nanowires is reviewed with an emphasis on size effects. The review covers existing characterization and analysis methods and summarizes data reported in the literature. It also provides an assessment of research needs and opportunities. Throughout the discussion, the importance of coupling experimental and computational studies is highlighted. This is crucial for obtaining unambiguous size effects of nanowire properties, which truly reflect the effect of scaling rather than a particular synthesis route. We show that such a combined approach is critical to establish synthesis‐structure‐property relations that will pave the way for optimal usage of piezoelectric nanowires.
A Polyaniline‐Coated Sulfur/Carbon Composite with an Enhanced High‐Rate Capability as a Cathode Material for Lithium/Sulfur Batteries
Authors: Li Guo‐Chun , Li Guo‐Ran , Ye Shi‐Hai , Gao Xue‐Ping 
Published: May 2012

AbstractPolyaniline‐coated sulfur/conductive‐carbon‐black (PANI@S/C) composites with different contents of sulfur are prepared via two facile processes including ball‐milling and thermal treatment of the conductive carbon black and sublimed sulfur, followed by an in situ chemical oxidative polymerization of the aniline monomer in the presence of the S/C composite and ammonium persulfate. The microstructure and electrochemical performance of the as‐prepared composites are investigated systematically. It is demonstrated that the polyaniline, with a thickness of ≈5–10 nm, is coated uniformly onto the surface of the S/C composite forming a core/shell structure. The PANI@S/C composite with 43.7 wt% sulfur presents the optimum electrochemical performance, including a large reversible capacity, a good coulombic efficiency, and a high active‐sulfur utilization. The formation of the unique core/shell structure in the PANI@S/C composites is responsible for the improvement of the electrochemical performance. In particular, the high‐rate charge/discharge capability of the PANI@S/C composites is excellent due to a synergistic effect on the high electrical conductivity from both the conductive carbon black in the matrix and the PANI on the surface. Even at an ultrahigh rate (10C), a maximum discharge capacity of 635.5 mA h per g of sulfur is still retained for the PANI@S/C composite after activation, and the discharge capacity retention is over 60% after 200 cycles.

AbstractWe present a boy diagnosed with partial 3p monosomy and partial 4q trisomy. The patient was 9 years of age with intellectual disability, dysmorphic features, and ataxia. A family history and medical evaluation showed that the father manifested similar facial dysmorphic features, intellectual disability, quadriparesis, and progressive cerebrospinal ataxia. The chromosomal aberration found in the proband was inherited from his father who was found to have a balanced reciprocal translocation of chromosomes 3p and 4q, which was in turn inherited from the paternal grandfather. The final cytogenetic diagnosis according to microarray was 46,XY,der(3)t(3;4)(p26.1;q32.2)arr 3p26.1(39,066–5,363,502)x1,4q32.2q35.2(162,555,236–191,173,881)x3. We describe the cytogenetic investigations that led to the identification of the breakpoints. In addition, we present an overview of the clinical features found in patients with partial 3p monosomies and partial 4q trisomies as reported in the literature. © 2012 Wiley Periodicals, Inc.

Published: May 2012

AbstractDeletions in chromosome 14q22–23 have been associated with variable manifestations including malformations of the eye, limbs, palate, and brain, and with developmental and growth delay. Haploinsufficiency of BMP4, OTX2 and possibly SIX6 are thought to contribute to the phenotype. We present a three generation family with four individuals carrying a 2.79 Mb microdeletion 14q22.1–22.2 encompassing BMP4 but not OTX2 nor SIX6. The highly variable manifestations in this family range from multiple congenital malformations with Robin sequence, microphthalmia, postaxial polydactyly, and developmental delay in the index patient to cleft uvula, growth delay, and mild developmental delay in her sister. The adults have a normal intelligence, postaxial polydactyly, and short stature or early cataract. Genotype–phenotype correlations suggest that the severity of eye manifestations in 14q22 deletions are influenced by the size of the deletion, but the marked intrafamilial variability observed in this family, as well as in familial BMP4 or OTX2 intragenic mutations points to additional modifiers outside this region. © 2012 Wiley Periodicals, Inc.

AbstractPatients with Xp deletions have short stature and may have some somatic traits typical of Turner syndrome (TS), whereas gonadal function is generally preserved. In most studies of these patients, microsatellites have been used to determine the break point of the Xp deletion. In the present study, we describe the clinical, cytogenetic, and chromosomal microarray (CMA) analysis of a family with an Xp22.33‐Xp22.12 deletion. Two female siblings, aged 8 years 9 months and 11 years 10 months, presented with short stature. The older sibling's height (index case) was 137.9 cm (−1.81 SDS) and the younger sibling's height was 118.6 cm (−2.13 SDS). The mother and both daughters had only a short stature; a skeletal survey showed normal findings except for mildly shortened 4th and 5th metacarpal bones. No features of TS were present. The deletion appeared terminal with a breakpoint within Xp22.2 located about 19.9 Mb from the Xp telomere. The deletion contained 102 protein‐coding genes. A probe of the end breakage point was located at the 19,908,986th base of the X chromosome, and a probe of the marginal normal region near the breakage point was located at the 19,910,848th base of the X chromosome. Therefore, the breakage point was concluded to be located between these two probes. In summary, we report a familial case of an Xp deletion. The findings of our study may be helpful in further analyzing the phenotypes associated with Xp deletions. © 2012 Wiley Periodicals, Inc.
Fe and Cu stable isotopes in archeological human bones and their relationship to sex

Published: May 2012

AbstractAccurate sex assignment of ancient human remains usually relies on the availability of coxal bones or well‐preserved DNA. Iron (Fe) and copper (Cu) stable isotope compositions (56Fe/54Fe and 65Cu/63Cu, respectively) were recently measured in modern human blood, and an unexpected result was the discovery of a 56Fe‐depletion and a 65Cu‐enrichment in men's blood compared to women's blood. Bones, being pervasively irrigated by blood, are expected to retain the 56Fe/54Fe and 65Cu/63Cu signature of blood, which in turn is useful for determining the sex of ancient bones. Here, we report the 56Fe/54Fe, 65Cu/63Cu, and 66Zn/64Zn ratios from a suite of well‐preserved phalanxes (n = 43) belonging to individuals buried in the 17th and 18th centuries at the necropolis of Saint‐Laurent de Grenoble, France, and for which the sex was independently estimated from pelvic bone morphology. The metals were purified from the bone matrix by liquid chromatography on ion exchange resin and the isotope compositions were measured by multiple‐collector inductively coupled plasma mass spectrometry. The results show that, as expected from literature data on blood, male bone iron is depleted in 56Fe and enriched in 65Cu relative to female. No sex difference is found in the 66Zn/64Zn ratios of bone. The concentration and isotopic data show no evidence of soil contamination. Four samples of five (77%) can be assigned their correct sex, a result comparable to sex assignment using Fe and Cu isotopes in blood (81%). Isotopic analysis of metals may therefore represent a valid method of sex assignment applicable to incomplete human remains. Am J Phys Anthropol 148:334–340, 2012. © 2012 Wiley Periodicals, Inc.

Published: May 2012

AbstractAlthough previous studies have characterized the genetic structure of populations from Haiti and Jamaica using classical and autosomal STR polymorphisms, the patrilineal influences that are present in these countries have yet to be explored. To address this lacuna, the current study aims to investigate, for the first time, the potential impact of different ancestral sources, unique colonial histories, and distinct family structures on the paternal profile of both groups. According to previous reports examining populations from the Americas, island‐specific demographic histories can greatly impact population structure, including various patterns of sex‐biased gene flow. Also, given the contrasting autosomal profiles provided in our earlier study (Simms et al.: Am J Phys Anthropol 142 (2010) 49–66), we hypothesize that the degree and directionality of gene flow from Europeans, Africans, Amerindians, and East Asians are dissimilar in the two countries. To test this premise, 177 high‐resolution Y‐chromosome binary markers and 17 Y‐STR loci were typed in Haiti (n= 123) and Jamaica (n= 159) and subsequently utilized for phylogenetic comparisons to available reference collections encompassing Africa, Europe, Asia (East and South), and the New World. Our results reveal that both studied populations exhibit a predominantly South‐Saharan paternal component, with haplogroups A1b‐V152, A3‐M32, B2‐M182, E1a‐M33, E1b1a‐M2, E2b‐M98, and R1b2‐V88 comprising 77.2% and 66.7% of the Haitian and Jamaican paternal gene pools, respectively. Yet, European derived chromosomes (i.e., haplogroups G2a*‐P15, I‐M258, R1b1b‐M269, and T‐M184) were detected at commensurate levels in Haiti (20.3%) and Jamaica (18.9%), whereas Y‐haplogroups indicative of Chinese [O‐M175 (3.8%)] and Indian [H‐M69 (0.6%) and L‐M20 (0.6%)] ancestry were restricted to Jamaica.

High capacity adsorption of malachite green in a mesoporous tyre‐derived activated carbon
Authors: Song X. , Xu R. , Wang K. 
Published: May 2012

ABSTRACTA mesoporous activated carbon derived from waste tyres was used to remove a toxic basic dye (malachite green oxalate, or MG) from aqueous solutions. The carbon contains a large volume fraction of mesopores and presents an excellent adsorption capacity of ~424 mg/g towards MG, which is much higher than a commercial carbon with similar surface area. The adsorption equilibrium and kinetics were found to follow Langmuir equation and second‐order kinetics, respectively. The structure of the carbon was characterised and based on which the dye adsorption mechanism was discussed. © 2012 Curtin University of Technology and John Wiley & Sons, Ltd.

Published: May 2012

AbstractIn this study, a 16 runs Taguchi method was applied as an experimental design to establish the optimum conditions for hydrogel nanoparticle preparation. Five relevant factors, chitosan (CS) concentration, pentasodium tripolyphosphate (TPP) concentration, CS‐to‐TPP volume ratio, addition time of the TPP solution to the CS solution, and temperature, were selected as the main determinants, and the effects of each factor on the size of the hydrogel nanoparticles were studied at four levels. The statistical analysis revealed that the most important factors contributing to the achievement of minimum particle size were the CS‐to‐TPP volume ratio and the CS concentration. By solving a set of equations derived from the differentiation of the final model, we established the optimum conditions for hydrogel nanoparticle preparation as follows: CS concentration = 0.28% w/v, TPP concentration = 3.17% w/v, TPP/CS = 1 : 8, temperature = 25.66°C, and addition time of the TPP solution to the CS solution = 0.4 min. Also, an analysis of response at the different levels of the factors indicated that there was no remarkable interaction between them. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2012
Synthesis of magnesium hydroxide nanofiller and its use for improving thermal properties of new poly(ether‐amide)
Authors: Shabanian Meisam , Ghanbari Davood 
Published: May 2012

AbstractA new poly(ether‐amide; PEA) as a source of polymeric matrix, containing flexible ether group in the main chain was synthesized by direct polycondensation reaction of 1,2‐(4‐carboxy phenoxy)ethane with 4,4‐diaminodiphenyl ether in a medium consisting of N‐methyl‐2‐pyrrolidone, triphenyl phosphite, calcium chloride, and pyridine. The resulting PEA was characterized by gel permeation chromatography (GPC), 1H NMR and FT‐IR spectroscopy. Magnesium Hydroxide (MH) nanostructure was synthesized by the reaction of magnesium sulfate and sodium hydroxide by sonochemical method. The MH particle was characterized by X‐ray diffraction (XRD) and scanning electron microscopy (SEM). Then Mg(OH)2 nanostructure was added to poly(ether‐amide) matrix and resulting nanocomposites were characterized by XRD, SEM, and Thermogravimetry Analysis (TGA). Thermal decomposition of the PEA shifted towards higher temperature in the presence of the magnesium hydroxide nanoparticles. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013

Published: May 2012

AbstractFor a batch emulsion polymerization of isoprene at 10°C in the presence of a chain transfer agent, a previous mathematical model (Minari et al., J. Appl. Polym. Sci. 2010, 116, 590) was extended for predicting the molecular weight distributions of all the generated long chain branched topologies; with each topology characterized by the number of tri‐ and tetra‐functional branches per molecule. According to the new model predictions, at the reaction end the linear topology remains as the most abundant (with ∼ 40% of the total mass), followed by the single trifunctionally branched topology (with ∼ 20% of the total mass). The model can be used for developing strategies for controlling the distribution of branches/molecule, for estimating melt viscosities, etc. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
A novel method to graft carbon nanotube onto carbon fiber by the use of a binder
Authors: Rong Huaiping , Han Keqing , Li Shuang , Tian Yingcai , Muhuoyu  
Published: May 2012

AbstractA novel method is developed for grafting multiwall carbon nanotubes (MWNTs) onto the surface of polyacrylonitrile‐based high strength (T300GB) carbon fiber. Functionalized MWNTs were well dispersed in the PVA solution and the carbon fiber was dip‐coated in this solution. After heat treatment of the coated carbon fiber under a nitrogen atmosphere, MWNTs with carboxyl groups were grafted onto the functionalized carbon fiber via chemical interaction. The resulting materials were characterized by Fourier transform infrared (FTIR), X‐ray photoelectron spectroscopy (XPS), Field emission scanning electron microscopy (FESEM), Raman spectrum and mechanical testing. FESEM observations revealed uniform coverage of carbon nanotubes on carbon fiber. The carbon fiber grafted with MWNTs improved the tensile strength by 12% with respect to the pristine carbon fiber. These results are supportive of good interfacial bonding between the carbon nanotubes (CNTs) and carbon fiber. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013

AbstractA new method of preparation of oligoetherols containing perhydro‐1,3,5‐triazine rings and boron atoms is presented. The oligoetherols were obtained in the reaction of 1,3,5‐tris(2‐hydroxyethyl) isocyanurate with boric acid followed by reaction with alkylene carbonates. The structure and physical properties of the products render them good candidate for preparing the polyurethane foams. The foams were obtained and their properties were compared with those synthesized from isocyanuric acid and alkylene carbonates. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
Synergistic effect of coupling agents on polypropylene‐based wood–plastic composites
Authors: Yeh Shu‐Kai , Kim Kwang‐Jea , Gupta Rakesh K. 
Published: May 2012

AbstractIn this study, polypropylene grafted with maleic anhydride (PP‐g‐MA) and styrene ethylene‐co‐butylene styrene block copolymer grafted with maleic anhydride (SEBS‐g‐MA) were used as coupling agents for polypropylene‐based wood–plastic composites containing 50 wt % wood flour. Adding up to 5 wt % PP‐g‐MA to the composite increased the tensile strength of the wood‐plastic composite (WPC) by almost 100% and the reversed‐notch Izod impact strength by more than 100%; the modulus remained essentially unchanged. By contrast, the same amount of SEBS‐g‐MA had a greater effect on the impact strength but a smaller influence on the tensile strength; in addition, the modulus was reduced. On using a combination of 2 wt % PP‐g‐MA and 1 wt % SEBS‐g‐MA, the impact strength of the composite could be increased significantly, but the tensile strength and modulus were not reduced to any appreciable extent relative to the use of PP‐g‐MA alone. Because WPCs are building products where minimizing costs is extremely important, this finding has important commercial implications. © 2012 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013
