Published: April 2013

At our institution surgical correction of symptomatic flat foot deformities in children has been guided by a paradigm in which radiographs and pedobarography are used in the assessment of outcome following treatment. Retrospective review of children with symptomatic flat feet who had undergone surgical correction was performed to assess the outcome and establish the relationship between the static alignment and the dynamic loading of the foot.A total of 17 children (21 feet) were assessed before and after correction of soft-tissue contractures and lateral column lengthening, using standardised radiological and pedobarographic techniques for which normative data were available.We found significantly improved static segmental alignment of the foot, significantly improved mediolateral dimension foot loading, and worsened fore-aft foot loading, following surgical treatment. Only four significant associations were found between radiological measures of static segmental alignment and dynamic loading of the foot.Weakness of the plantar flexors of the ankle was a common post-operative finding. Surgeons should be judicious in the magnitude of lengthening of the plantar flexors that is undertaken and use techniques that minimise subsequent weakening of this muscle group.Cite this article: Bone Joint J 2013;95-B:706–13.
Effects of Reduced Juice Allowances in Food Packages for the Women, Infants, and Children Program
Authors: Andreyeva Tatiana , Luedicke Joerg , Tripp Amanda S. , Henderson Kathryn E. 
Published: April 2013

OBJECTIVES:
In 2009, the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) implemented revisions to the composition and quantities of WIC food packages. Juice allowances were reduced by approximately half. This report describes changes in purchases of 100% juice and other beverages among WIC participants after the WIC revisions.

METHODS:
Scanner data from a New England supermarket chain were used to assess juice and other beverage purchases among 2137 WIC-participating households during a 2-year period (N = 36 051 household-months). Purchased beverage amounts were compared before (January–September 2009) and after (January–September 2010) implementation of the revised WIC packages. Generalized estimating equation models were used.

RESULTS:
Before the revisions, WIC juice accounted for two-thirds of purchased juice volume among WIC households. After implementation of the revisions, WIC juice purchases were reduced on par with allowance changes (43.5% of juice volume, 95% confidence interval [CI] 41.9%–45.1%). This reduction was only partly compensated for by an increase of 13.6% (8.4%–19.0%) in juice purchases using personal and other non-WIC funds. In total, juice purchases declined by 23.5% (21.4%–25.4%) from an adjusted monthly total of 238 oz to 182 oz per household. WIC households increased purchases of fruit drinks by 20.9% (14.9%–27.3%) and other noncarbonated beverages by 21.3% (12.1%–31.2%) but purchased 12.1% (8.1%–15.0%) less soft drinks.

CONCLUSIONS:
After the WIC revisions, total purchases of 100% juice among WIC households declined by about a quarter, with little compensation occurring from non-WIC funds for juice and other beverages. The public health impact of the shift in beverage purchase patterns could be significant.

Experiencing and Coping with Stress of Political Uncertainty: Gender Differences among Mental Health Professionals
Authors: Shamai Michal 
Published: April 2013

This study aimed to investigate how mental health professionals experience and cope with the same stressor that affects their clients. It focuses on Israeli mental health professionals who live and work in the West Bank and were exposed to long periods of terror during the Palestinian uprising (the Intifada) and to the threat of possible relocation based on the Oslo Agreement. The sample included fourteen women and eleven men, representing about 15% of the Israeli mental health professionals who live and work among Jewish populations in the West Bank. Data were collected in April 1995 during the government of the left-wing regime, when the stress of possible relocation was very intense. The results, based on quantitative and qualitative analysis, indicate that being marginalized is an important aspect of creating the stress. Commitment to the goal was found to be the stronger variable affecting coping. As for gender differences, the quantitative results and part of the qualitative results supported the “role constraint” hypothesis. However, both males and females of the mental health professions were found to experience their response to stress and to use coping strategies according to the “socialization” hypothesis.

Oxygen sensing materials based on clay/metalloporphyrin hybrid systems
Authors: Čeklovský Alexander , Takagi Shinsuke 
Published: April 2013

Abstract
This study was focused on the investigation of novel hybrid organo/inorganic systems for oxygen sensing applications. As a host material, a synthetic clay mineral Sumecton SA was chosen, while, as guest materials, metalloporphyrins containing Pt(II) and Pd(II) were chosen. These are known to be very efficient agents for sensing applications because of a “heavy atom effect”. This effect promotes a spin-orbit coupling, resulting in the fact that almost all of the radiation from a singlet excited state undergoes intersystem crossing, followed by a de-excitation via a triplet state. The combination of metalloporphyrin and layered materials enables unique oxygen sensing properties due to the steric effects of layered materials. The result is that the emission from the membrane was sensitive at the range around aerobic conditions. The spectroscopic analysis of hybrid systems — clay/porphyrin membranes (CPMs) showed that these materials can serve as prospective candidates for the construction of effective, reliable and economical oxygen sensors.
In vitro magnetic hyperthermia response of iron oxide MNP’s incorporated in DA3, MCF-7 and HeLa cancer cell lines
Authors: Gkanas Evangelos 
Published: April 2013

Abstract
In the current work, iron oxide magnetic nanoparticles (MNP’s) were synthesized by thermal decomposition of Fe(acac)3-(iron acetylacetonate) compounds in high-boiling organic solvents containing stabilizing surfactants and examined as possible agents for magnetic hyperthermia treatment, according to their structural, magnetic and heating properties. Three different cancer cell lines (DA3, MCF-7 and HeLa cell lines) were used to assess the suitability of the MNP’s. The experimental results proved that the synthesized MNPs are non-toxic and the uptake efficiency was extremely good. Further, from in vitro hyperthermia results, very fast thermal response was observed (reaching hyperthermia levels in less than 200 s), which minimize the duration of the cell and human body exposure in a high frequency AC external magnetic field.

Published: April 2013

Study Design Planned secondary analysis of a randomized controlled trial comparing neural tissue management (NTM) to advice to remain active. Objective To develop a model that predicts the likelihood of patient-reported improvement following NTM. Background Matching patients to an intervention they are likely to benefit from potentially improves outcomes. However, baseline characteristics that predict patients' responses to NTM are unknown. Methods Data came from 60 consecutive adults who had nontraumatic, nerve-related neck and unilateral arm pain for at least 4 weeks. Participants were assigned to a group that received NTM (n = 40), which involved brief education, manual therapy, and nerve gliding exercises for 4 treatments over 2 weeks, or to a group that was given advice to remain active (n = 20), which involved instruction to continue their usual activities. The participants' global rating of change at a 3- to 4-week follow-up defined improvement. Penalized regression of NTM data identified the best prediction model. A medical nomogram was created for prediction model scoring. Post hoc analysis determined whether the model predicted a specific response to NTM. Results Absence of neuropathic pain qualities, older age, and smaller deficits in median nerve neurodynamic test range of motion predicted improvement. Prediction model cutoffs increased the likelihood of improvement from 53% to 90% (95% confidence interval: 56%, 98%) or decreased the likelihood of improvement to 9% (95% confidence interval: 1%, 42%). The model did not predict the outcomes of the advice to remain active group. Conclusion Baseline characteristics of patients with nerve-related neck and arm pain predicted the likelihood of improvement with NTM. Model performance needs to be validated in a new sample using different comparison interventions and longer follow-up. Australian New Zealand Clinical Trials Registry (ACTRN 12610000446066).

Published: April 2013

• Premise of the study: Transcriptome sequence data were used to design microsatellite primers for two widespread Central American Begonia species, B. heracleifolia and B. nelumbiifolia, to investigate population structure and hybridization.• Methods and Results: The transcriptome from vegetative meristem tissue from the related B. plebeja was mined for microsatellite loci, and 31 primer pairs amplified in the target species. Fifteen primer pairs were combined in two multiplex PCR reactions, which amplified an average of four alleles per locus.• Conclusions: The markers developed will be a valuable genetic resource for medium‐throughput genotyping of Central American species of Begonia sect. Gireoudia. A subset of these markers have perfect sequence matches to Asian B. venusta, and are promising for studies in other Begonia sections.
Prostaglandin E2–Induced Changes in Alveolar Macrophage Scavenger Receptor Profiles Differentially Alter Phagocytosis of Pseudomonas aeruginosa and Staphylococcus aureus Post–Bone Marrow Transplant

Abstract
The effectiveness of hematopoietic stem cell transplantation as a therapy for malignant and nonmalignant conditions is complicated by pulmonary infections. Using our syngeneic bone marrow transplant (BMT) mouse model, BMT mice with a reconstituted hematopoietic system displayed increased susceptibility to Pseudomonas aeruginosa and Staphylococcus aureus. BMT alveolar macrophages (AMs) exhibited a defect in P. aeruginosa phagocytosis, whereas S. aureus uptake was surprisingly enhanced. We hypothesized that the difference in phagocytosis was due to an altered scavenger receptor (SR) profile. Interestingly, MARCO expression was decreased, whereas SR-AI/II was increased. To understand how these dysregulated SR profiles might affect macrophage function, CHO cells were transfected with SR-AI/II, and phagocytosis assays revealed that SR-AI/II was important for S. aureus uptake but not for P. aeruginosa. Conversely, AMs treated in vitro with soluble MARCO exhibited similar defects in P. aeruginosa internalization as did BMT AMs. The 3′-untranslated region of SR-AI contains a putative target region for microRNA-155 (miR-155), and miR-155 expression is decreased post-BMT. Anti–miR-155–transfected AMs exhibited an increase in SR-AI/II expression and S. aureus phagocytosis. Elevated PGE2 has been implicated in driving an impaired innate immune response post-BMT. In vitro treatment of AMs with PGE2 increased SR-AI/II and decreased MARCO and miR-155. Despite a difference in phagocytic ability, BMT AMs harbor a killing defect to both P. aeruginosa and S. aureus. Thus, our data suggest that PGE2-driven alterations in SR and miR-155 expression account for the differential phagocytosis of P. aeruginosa and S. aureus, but impaired killing ultimately confers increased susceptibility to pulmonary infection.
A Matrix-Vector Operation-Based Numerical Solution Method for Linear m-th Order Ordinary Differential Equations: Application to Engineering Problems
Authors: Aminbaghai M. , Dorn M. , Eberhardsteiner J. , Pichler B. 
Published: April 2013

AbstractMany problems in engineering sciences can be described by linear, inhomogeneous,m-th order ordinary differential equations (ODEs) with variable coefficients. For this wide class of problems, we here present a new, simple, flexible, and robust solution method, based on piecewise exact integration of local approximation polynomials as well as on averaging local integrals. The method is designed for modern mathematical software providing efficient environments for numerical matrix-vector operation-based calculus. Based on cubic approximation polynomials, the presented method can be expected to perform (i) similar to the Runge-Kutta method, when applied to stiff initial value problems, and (ii) significantly better than the finite difference method, when applied to boundary value problems. Therefore, we use the presented method for the analysis of engineering problems including the oscillation of a modulated torsional spring pendulum, steady-state heat transfer through a cooling web, and the structural analysis of a slender tower based on second-order beam theory. Related convergence studies provide insight into the satisfying characteristics of the proposed solution scheme.
Matching Boundary Conditions for Scalar Waves in Body-Centered-Cubic Lattices
Authors: Fang Ming , Wang Xianming , Li Zhihui , Tang Shaoqiang 
Published: April 2013

AbstractMatching boundary conditions (MBC’s) are proposed to treat scalar waves in the body-centered-cubic lattices. By matching the dispersion relation, we construct MBC’s for normal incidence and incidence with an angle α. Multiplication of MBC operators then leads to multi-directional absorbing boundary conditions. The effectiveness are illustrated by the reflection coefficient analysis and wave packet tests. In particular, the designed M1M1 treats the scalar waves in a satisfactory manner.
Déterminants de l’internationalisation des PME françaises
Authors: Lecerf Marjorie-Annick 
Published: April 2013

L’importance relative des différents déterminants traditionnels de l’internationalisation demeure imparfaitement connue. Si pendant longtemps la taille de la firme est apparue comme le déterminant majeur, des analyses empiriques ont révélé que d’autres facteurs tels le milieu internationalisant et le dirigeant influencent significativement le développement international. Une approche centrée sur les principaux vecteurs de la compétitivité des firmes et s’appuyant directement sur les qualités intrinsèques des PME permet d’offrir un angle d’analyse différent.
L’objectif de cette étude est de démontrer que le processus d’internationalisation suit un développement non linéaire déterministe, conditionné par les caractéristiques idiosyncratiques de la PME. Nos recherches s’inscrivent dans la cadre de l’internationalisation des petites et moyennes entreprises. Nous chercherons à préciser les déterminants de cette internationalisation des PME françaises en observant leurs performances à l’export.
Les résultats montrent un impact positif entre une série de facteurs microéconomiques et sectoriels, et les exportations de 253 entreprises. Plus précisément, ils révèlent qu’une combinaison de facteurs comprenant l’organisation, l’innovation, les TIC, le dirigeant et la maîtrise de langues étrangères fait fortement varier les exportations dans tous les secteurs.

Published: April 2013

AbstractEstrogens play important roles in the cell proliferation and invasion of estrogen‐dependent human neoplasms. Aromatase overexpression has been also reported in hepatitis and hepatocellular carcinoma (HCC) compared with normal liver but its details in these hepatic disorders have remained unclear. Therefore, in this study, we first immunolocalized aromatase using immunohistochemistry in patients with liver cirrhosis, steatosis, hepatitis, HCC, and metastasis liver carcinoma (MLC) in order to study the detailed status of intrahepatic aromatase. Aromatase immunoreactivity was predominantly detected in nonneoplastic hepatocytes around tumor cells. We then evaluated the effects of an interaction between hepatocytes and carcinoma cells upon aromatase mRNA expression, using HepG2 as a substitute model of hepatocytes by coculture systems. Aromatase mRNA levels in HepG2 were significantly increased by coculture with all carcinoma cell lines examined. We also evaluated alternative splicing of aromatase exon 1 but the same splicing variant was used in HepG2 cells regardless of carcinoma cell lines employed in the coculture system. These findings obtained in HepG2 indicated that carcinoma cells, whether metastatic or primary, induced aromatase expression in adjacent normal hepatocytes possibly through the soluble aromatase inducible factors in human hepatic microenvironments.

Computation of the two‐phase flow properties of intermediate‐wet porous media: A pore network approach
Authors: Tsakiroglou Christos D. 
Published: April 2013

AbstractA pore‐and‐throat network including fractal‐like roughness features along its surface is employed to simulate primary drainage and secondary imbibition by accounting for the quasistatic motion of menisci in pores and throats and varying the contact angle from 0° (strongly water‐wet conditions) to 180° (strongly oil‐wet conditions). The angle of sharpness of roughness features defines a range of contact angles within which the cross‐section of the throat or pore is occupied completely by the one fluid and conditions of intermediate wettability are established. In contrast, outside this range, both fluids may coexist in a pore or throat. Such differences on the fluid distribution at the pore level affect strongly the capillary, electrical and hydraulic properties of the porous medium and are reflected in the capillary pressure, resistivity index and relative permeability curves. The simulator is used to calculate the aforementioned two‐phase flow coefficients as the pore system transits from strongly water‐wet or strongly oil‐wet to intermediate‐wet. The capillary pressure curves are always sensitive to the wetting state and the particular value of the contact angle. The relative permeability and resistivity index curves for secondary imbibition are grouped in families of curves which are sensitive mainly to the wetting state (water‐wet, intermediate‐wet/water‐wet pores, intermediate‐wet/oil‐wet pores, oil‐wet) rather than to the particular value of the contact angle.

Published: April 2013

BackgroundSinonasal undifferentiated carcinoma (SNUC) remains a poorly characterized malignancy at both the clinical and molecular level, and, consequently, the optimal treatment strategy remains undefined.MethodsWe used a mass spectroscopy–based approach (Sequenom) to evaluate 95 hallmark single nucleotide variations (SNVs) within 12 oncogenes or tumor suppressor genes (AKT, BRAF, CDK4, Beta‐catenin, epidermal growth factor receptor [EGFR], FBXW7, JAK2, c‐KIT, KRAS, PDGFR, PI3K, and vascular endothelial growth factor [VEGF]) in 13 histologically confirmed SNUC cases.ResultsNone of the samples demonstrated activating mutations in any of the 95 SNVs.ConclusionSelect clinically relevant activating genomic mutations were not identified in the 13 patient samples. However, polymorphisms were noted within the promoter region of VEGF. These may merit future studies as predictive biomarkers for treatment response or overall survival. Additionally, future studies focusing on larger tumor sets and utilizing whole genome or exome sequencing may help define genetic aberrations in SNUC that can be clinically targeted with available or emerging biological agents. © 2013 Wiley Periodicals, Inc.
