Published: June 2013

AbstractBackground:Symptom overlap between autism spectrum disorders (ASD) and social anxiety disorder has been reported. However, few reports exist on the associations between autistic traits and social anxiety in young adults.Methods:Autistic traits and social anxiety were assessed using the Autism-Spectrum Quotient (AQ) and the Liebowitz Social Anxiety Scale (LSAS), respectively. The survey was performed as part of the student health check-up at admission to our school, Kochi University. The relationship between the AO and LSAS scores were analyzed.Results:In all, 1479 students (77.2%) completed both the questionnaires. The overall AQ score was significantly related to the score on the Japanese version of the LSAS (LSAS-J) (Spearman’s correlation coefficient; 0.46, p<0.001). The group of students with AQ≥33 had significantly higher total and subscale scores on the LSAS-J as compared to the group with AQ<33, while the group with LSAS-J≥44 showed significantly higher scores on all the subscales of the AQ, except “Attention to detail,” as compared to the group with LSAS-J<44.Conclusions:The results suggest that both students diagnosed as having ASD and those with autistic traits may experience anxiety symptoms. The score for “Attention to detail” on the AQ, which was not related to the presence of social anxiety, may be useful in discriminating between autistic traits and social anxiety.
Configuration of Jacobian Matrix in Steady-State Voltage Stability Analysis Based on Rotor Flux Dynamics of Rotating Machines
Authors: Li Shenghu 
Published: June 2013

Abstract
In the existing literatures, modal analysis for steady-state voltage stability is based on the reduced Jacobian matrix, i.e. active power equations are eliminated, and reactive power equations of the constant power/voltage buses (PV buses) are ignored in the polar coordinate expression, which is actually designed for voltage controllability, but questionable for voltage stability.In this article, power outputs of the rotating machines are newly decomposed to the steady-state and dynamic components, with the latter proportional to derivative of the rotor flux. Therefore, neither the active nor the reactive power equations of the rotating machines may be eliminated or ignored in the Jacobian matrix. Only the static buses with constant load impedance should be eliminated. Numerical results show that elimination of active power equations or ignorance of reactive power equations of the rotating machines will yield optimistic stability margins, while including power equations of static load buses yields pessimistic stability margin. It is also find that more static load component yields larger stability margin.

Abstract

Objective: This study aims to treat patients with preterm premature rupture of the membranes (PPROM) and anhydramnion using continuous amnioinfusion through a subcutaneously implanted port system.

Methods: An amniotic fluid replacement port system was implanted in seven patients with PPROM and anhydramnion starting at the 20th week of gestation (range, 14–26 weeks) for long-term amnioinfusion. Saline solutions (2 L/day; Jonosteril®, Sterofundin®, isotonic NaCl 0.9% solution, lactated Ringer’s solution) and a hypotonic aqueous composition with reduced chloride content similar to the electrolyte concentration of human amniotic fluid were used for the continuous amnioinfusion.

Results: The mean duration of the PPROM delivery interval continued for 49 days (range, 9–69 days), with 3 weeks of amnioinfusion via the port system (range, 4–49). The newborns showed no signs of lung hypoplasia.

Conclusion: Long-term lavage of the amniotic cavity via a subcutaneously implanted port system in patients with PPROM and anhydramnion may help prolong the pregnancy and avoid fetal lung hypoplasia. A hypotonic aqueous composition with reduced chloride content similar to human amniotic fluid can be safely used for amnioinfusion. Prospective randomized studies are ongoing.

Published: June 2013

AbstractThe use of nanoparticles in tumor imaging, molecular imaging, and drug delivery has significantly expanded in the last few years. The relatively new field of “theranostics” combines their capacity for drug delivery with their potential as contrast agents. Depending on the imaging modality used, several types of nanoparticles are available, such as gold for optical imaging or superparamagnetic iron oxide for magnetic resonance imaging. This review will give a short overview of the different types of nanoparticles as well as their development and potential application in recent years. Furthermore, it describes the research on classic imaging modalities as well as on new techniques to image nanoparticles in vivo and focuses on magnetic-based imaging modalities.

Molecular iodine/polymer complexes
Authors: Moulay Saad 
Published: June 2013

Abstract
A unique feature of molecular iodine by far, is its ability to bind to polymeric materials. A plethora of natural and synthetic polymers develop complexes when treated with molecular iodine, or with a mixture of molecular iodine and potassium iodide. Many unexpected findings have been encountered upon complexation of iodine and the polymer skeleton, including the color formation, the polymer morphology changes, the complexation sites or regions, the biological activity, and the electrical conductivity enhancement of the complexes, with polyiodides (In¯), mainly I3¯ and I5¯, as the actual binding species. Natural polymers that afford such complexes with iodine species are starch (amylose and amylopectin), chitosan, glycogen, silk, wool, albumin, cellulose, xylan, and natural rubber; iodine-starch being the oldest iodine-natural polymer complex. By contrast, numerous synthetic polymers are prone to make complexes, including poly(vinyl alcohol) (PVA), poly(vinyl pyrrolidone) (PVP), nylons, poly(Schiff base)s, polyaniline, unsaturated polyhydrocarbons (carbon nanotubes, fullerenes C60/C70, polyacetylene; iodine-PVA being the oldest iodine-synthetic polymer complex.
Proteomics quantification of protein nitration
Authors: Evans Adam R. , Robinson Renã A.S. 
Published: June 2013

Abstract
Protein tyrosine nitration is a post-translational modification (PTM) that can occur in biological systems under conditions of oxidative stress. This PTM can impact protein structure and function and has been linked to diseases such as Alzheimer’s disease, cardiomyopathy, and arthritis. In order to understand the role that 3-nitrotyrosine (3NT) plays in disease states, a better understanding at the macromolecular level is necessary. Proteomics is a powerful approach that can simultaneously measure hundreds to thousands of proteins in normal or diseased states and thus can be helpful in the analysis of 3NT-modified proteins. Recently, some attention has been focused on the development of proteomic workflows that provide enrichment, characterization, and relative quantification of 3NT-modified proteins. These approaches rely on gel electrophoresis, liquid chromatography, and mass spectrometry (MS) techniques. This review provides an overview of current proteomics approaches for 3NT-modified proteins and highlights current MS-based methods for quantification of this PTM.

AbstractThe complex spin order of hyperpolarized multispin systems giving rise to anomalous NMR spectral patterns that vary with the RF excitation angle is analyzed by decomposing its nutation behavior in a superposition of Fourier harmonics. The product operator formalism is applied to calculating the spectral contributions of the various mutual alignments of scalar coupled spins. Two cases are treated, namely systems exhibiting only differences in population of their spin states and systems showing in addition zero-quantum coherences between states, a situation often seen at hyperpolarization. After deriving the general solution a number of representative examples are discussed in detail. The theoretical treatment is applied to analyzing the spin order observed in a hyperpolarized two-spin system that is prepared in the singlet state by para-hydrogen induced polarization.

Published: June 2013

ABSTRACTThe thermal transport in amorphous/crystalline silicon superlattices with means of molecular dynamics is presented in the current study. The procedure used to build such structures is discussed. Then, thermal conductivity of various samples is studied as a function of the periodicity of regular superlattices and of the applied temperature. Preliminarily results show that for regular amorphous/crystalline superlattices, the amorphous regions control the heat transfer within the structures. Secondly, in the studied cases thermal conductivity weakly varies with the temperature. This, points out the presence of a majority of non-propagating vibrational modes in such systems.

ABSTRACTThis study reports on the fabrication of nanofluids/microfluids (NFs/MFs) with experimental and theoretical investigation of thermal conductivity (TC) and viscosity of diethylene glycol (DEG) base NFs/MFs containing copper nanoparticles (Cu NPs) and copper microparticles (Cu MPs). For this purpose, Cu NPs (20-40 nm) and Cu MPs (0.5-1.5 μm) were dispersed in DEG with particle loading between 1 wt% and 3 wt%. Ultrasonic agitation was used for dispersion and preparation of stable NFs/MFs, and thus the use of surfactants was avoided. The objectives were investigation of impact of size of Cu particle and concentration on TC and viscosity of NFs/MFs on DEG as the model base liquid. The physicochemical properties of all particles and fluids were characterized by using various techniques including Transmission Electron Microscopy (TEM), Scanning Electron Microscopy (SEM) and Dynamic Light Scattering (DLS) techniques. Fourier Transform Infrared Spectroscopy (FTIR) analysis was performed to study particles’ surfaces. NFs and MFs exhibited a higher TC than the base liquid, while NFs outperformed MFs showing a potential for their use in heat exchange applications. The TC and viscosity of NFs and MFs were presented, along with a comparison with values from predictive models. While Maxwell model was good at predicting the TC of MFs, it underestimated the TC of NFs, revealing that the model is not directly applicable to the NF systems.
Heat Transport between Heat Reservoirs Mediated by Quantum Systems
Authors: Panasyuk George Y. , Levin George A. , Yerkes Kirk L. 
Published: June 2013

ABSTRACTWe explore a model of heat transport between two heat reservoirs mediated by a quantum particle. The reservoirs are modeled as ensembles of harmonic modes linearly coupled to the mediator. The steady state heat current, as well as the thermal conductance are obtained for arbitrary coupling strength and will be analyzed for the cases of weak and strong coupling regimes. It is shown that the violation of the virial theorem – the imbalance between the average potential and kinetic energy of the mediator – can be considered as a measure of the coupling strength that takes into account all the relevant factors. The dependence of the thermal conductance on the coupling strength is non-monotonic and displays a maximum. Temperature dependence of the heat conductance may reach a plateau at intermediate temperatures, similar to the classical plateau at high temperatures. We will discuss the origin of Fourier’s law in a chain of macroscopically large, but finite subsystems coupled by the quantum mediators. We will also address the origin of the anomalously large heat current between the scanning tunneling microscope tip and the substrate in deep vacuum which was found in recent experiments.

Introduction: When planning excisional surgery, alterations in the oral mucosa, particularly in esthetically important areas, represent a challenge. For cases involving an exophytic lesion with a vegetative tumoral aspect, a clinician may prioritize obtaining a definitive diagnosis by histopathologic and histochemical examinations over the preservation of esthetics or maintenance of the involved tooth.Case Presentation: A painless, hard lesion with normal coloration was present in the maxillary left central incisor of a patient for at least 6 years. A biopsy was performed to preserve oral mucosa and a treatment plan was established that included endodontic retreatment and prosthetic restoration. The histopathologic diagnosis was oral focal mucinosis, an uncommon and poorly characterized type of lesion.Conclusion: A conservative biopsy of the lesion facilitated an accurate diagnosis, promoted the patient's comfort, and achieved satisfactory esthetic results.

Published: June 2013

Introduction: The oral cavity is considered an easily accessible window to the body. The mouth is frequently involved in conditions that affect multiple organs. In many instances, oral involvement precedes the appearance of many other symptoms or lesions. A complete examination of the oral cavity provides a gateway for an accurate diagnosis and precise management of many systemic conditions. Gingival enlargement is one of the varied manifestations of many systemic diseases. Here, a case report of a gingival enlargement is presented that provided information for the diagnosis of post‐primary pulmonary tuberculosis.Case Presentation: A 62‐year‐old female presented with a persistent gingival enlargement of 6‐month duration, which was non‐responsive to periodontal therapy. A complete general examination with the help of additional diagnostic aids provided the diagnosis of post‐primary pulmonary tuberculosis.Conclusion: Clinicians should be aware of the unusual forms of common diseases, which will aid in early diagnosis and proper patient management.
Treatment of Cement‐Associated Peri‐Implantitis Using Tetracycline and Enamel Matrix Derivative: A Case Report
Authors: Rozenfeld Helen , Iacono Vincent J. 
Published: June 2013

Introduction: This case report describes the treatment of peri‐implantitis around a restored single‐unit implant.Case Presentation: Clinical findings included deep probing depths (PDs), bleeding on probing (BOP), and suppuration. Radiographs suggested crater‐like bone loss. The area was surgically treated via an access flap. The peri‐implant defect was associated with cement that was found below the cement‐retained permanent restoration. The cement was removed, and the implant was treated with tetracycline and enamel matrix derivative (EMD). After an uneventful 10‐month period of healing, there was a significant reduction in PD and absence of BOP and suppuration. In addition, there was radiographic evidence of new bone formation.Conclusion: This case report proposes a new technique for treating peri‐implantitis and a new application for EMD.

Abstract.We prove that for every ordinary genus-2 curve X over a finite field κ of characteristic 2 with Aut(X/κ) = ℤ/2ℤ × S3 there exist SL(2; κ[[s]])-representations of π1(X) such that the image of π1(X̄) is infinite. This result produces a family of examples similar to Y. Laszlo’s counterexample to A. J. de Jong’s question regarding the finiteness of the geometric monodromy of representations of the fundamental group.

Management of the Internal Nasal Valve
Authors: Li Shia Ng , Stephen Lo 
Published: June 2013

ABSTRACTNasal obstruction is one of the most common nose complaints. Internal nasal valve dysfunction is an important cause of nasal obstruction, particularly in patients who have a previous history of nasal trauma or reduction rhinoplasty. Correct assessment is crucial for accurate diagnosis and appropriate management planning. Various surgical and nonsurgical modalities for addressing the problem of internal nasal valve collapse are being reviewed in this paper. Each technique have their own advantages and disadvantage, and the choice depends on the underlying pathology, patient preference, availability of graft material. The rhinoplasty surgeon should have a thorough understanding of the available options as part of his/her armamentarium in dealing with internal nasal valve pathology.How to cite this articleShia Ng L, Lo S.

Napâttuit: Wood use by Labrador Inuit and its impact on the forest landscape
Authors: Lemus-Lauzon Isabel , Bhiry Najat , Woollett James 
Published: June 2013

In Nunatsiavut, recent studies have shown that major changes to forest tundra ecosystems have occurred over the past two centuries, including a shift in the abundance and range of tree/shrub species. Although this trend could be due to the highly variable climate of this period, we should also consider anthropogenic factors, such as wood harvesting, when conducting ecological studies of forest dynamics. Based on a literature review, interviews, and field observations, this article documents the interactions between residents of Nain (Nunatsiavut) and the forest landscape since the late 18th century. Nain is one of the few Inuit communities south of the tree line, and its inhabitants seem to have had an ambivalent and changing relationship with their forest landscape. Thus, though probably perceived initially as potentially dangerous, the forest has gradually been integrated into land use patterns and helped shape some aspects of Labrador Inuit culture. For Nain’s inhabitants, wood use has been continuous but not homogenous over time. Patterns of use and harvesting have changed with the socio-economic setting and have left their traces on the region’s forest stands, as is evident from the abundance of cut stumps and the scarcity of naturally dead trees.

AbstractThe utilization of hydrogels in soft electronics has led to significant progress in the field of wearable and implantable devices. However, challenges persist in hydrogel electronics, including the delicate equilibrium between stretchability and electrical conductivity, intricacies in miniaturization, and susceptibility to dehydration. Here, a lignin‐polyacrylamide (Ag‐LPA) hydrogel composite endowed with anti‐freeze, self‐adhesive, exceptional water retention properties, and high stretchability (1072%) is presented. Notably, this composite demonstrated impressive electrical conductivity at room temperature (47.924 S cm−1) and extremely cold temperatures (42.507 S cm−1). It is further proposed for microfluidic‐assisted hydrogel patches (MAHPs) to facilitate customizable designs of the Ag‐LPA hydrogel composite. This approach enhances water retention and offers versatility in packaging materials, making it a promising choice for enduring soft electronics applications. As a proof‐of‐concept, soft electronics across diverse applications and dimensions, encompassing healthcare monitoring, environmental temperature sensing, and 3D‐spring pressure monitoring electronics are successfully developed. The scenery of an extremely cold environment is further extended. The conductivity of the embedded Ag‐LPA hydrogel composite unveils the potential of MAHPs in polar rescue missions. It is envisioned that MAHPs will impact the development of sophisticated and tailored soft electronics, thereby forging new frontiers in engineering applications.
