AbstractIntraoperative neural monitoring (IONM) during thyroid and parathyroid surgery has gained widespread acceptance as an adjunct to the gold standard of visual nerve identification. Despite the increasing use of IONM, review of the literature and clinical experience confirms there is little uniformity in application of and results from nerve monitoring across different centers. We provide a review of the literature and cumulative experience of the multidisciplinary International Neural Monitoring Study Group with IONM spanning nearly 15 years. The study group focused its initial work on formulation of standards in IONM as it relates to important areas: 1) standards of equipment setup/endotracheal tube placement and 2) standards of loss of signal evaluation/intraoperative problem‐solving algorithm. The use of standardized methods and reporting will provide greater uniformity in application of IONM. In addition, this report clarifies the limitations of IONM and helps identify areas where additional research is necessary. This guideline is, at its forefront, quality driven; it is intended to improve the quality of neural monitoring, to translate the best available evidence into clinical practice to promote best practices. We hope this work will minimize inappropriate variations in monitoring rather than to dictate practice options. Laryngoscope, 121:S1–S16, 2011

Published: August 2010

AbstractObjectives/Hypothesis:To describe our experience with the use of intralesional corticosteroid injection and dilatation (ILCD) in the management of subglottic stenosis (SGS).Study Design:Retrospective chart review.Methods:A retrospective chart review was performed of all patients with SGS requiring ILCD, from 2003 to 2008, at the Department of Otolaryngology–Head and Neck Surgery, Mount Sinai Hospital, Toronto, Canada.Results:Twelve patients with SGS underwent 36 ILCD operations with a mean of three procedures per patient. We identified eight patients with Wegener's granulomatosis (WG) and four patients without WG. The eight WG patients received an average of 3.37 procedures, whereas non‐WG patients required an average of 2.25 procedures. This maintained airway patency and symptom control for an average of 11.9 and 8.1 months, respectively. Only one complication was identified, and no long‐term sequelae were found. No patients required new tracheotomies and one patient with a previous tracheotomy was successfully decannulated.Conclusions:Our data supports the use of ILCD as a safe and effective treatment of SGS in both WG and non‐WG patients.

Treatment success for age‐related vocal fold atrophy
Authors: Gartner‐Schmidt Jackie , Rosen Clark 
Published: August 2010

AbstractObjectives/Hypothesis:To characterize perceived voice handicap of patients diagnosed with vocal fold atrophy and review treatment success.Study Design:Retrospective study.Methods:Two hundred seventy‐five patients diagnosed with vocal fold atrophy (January 2007–January 2009) were reviewed from a preexisting clinical database. Outcome measures included pre/post‐treatment Voice Handicap Index‐10 and data from a voice therapy discharge survey.Results:Five groups emerged from the data set. Group A: patients who had no follow‐up (69%). After removing group A from the data set, the following groups emerged: group B: patients who had no treatment but some follow‐up (31%); group C: patients who had voice therapy only (44%); group D: patients who had surgery only (15%); and group E: patients who had voice therapy first and subsequent surgery (9%). The perceived voice handicap severity was worse for groups C and D compared to groups A, B, and E. Treatment success outcomes showed that groups C (36%), D (56%), and E (17%) only improved marginally. However, 81% of patients diagnosed with atrophy believed that voice therapy helped them but only by 48%.Conclusions:Treatment success for age‐related vocal fold atrophy is poor to moderately poor for this cohort of patients.

A Magnetic Composite for Cleaning of Oil Spills on Water
Authors: Gomes de Souza Fernando , Marins Jéssica Alves , Rodrigues Cezar H. M. , Pinto José Carlos 
Published: August 2010

AbstractThe production of magnetic polymer composites for cleaning of oil spills on water is investigated. The polymer matrix consists of a biopolymer material (alkyd resin), which is cured with TDI in the presence of a magnetic powder (maghemite, γ‐Fe2O3), which is incorporated into the final polymer material in situ. Obtained polymer resins were characterized through magnetic force, AFM and WAXS/SAXS, showing that the proposed preparation technique leads to production of magnetic nanocomposites. Additionally, oil removal tests performed with polymer beads showed that the polymer product can be used to remove considerable amounts of oil from the surface of aqueous environments. In the best case, one part of the polymer product could be used to remove more than eight parts of oil from water.magnified image
Knowledge‐Based Tailoring of Gelatin‐Based Materials by Functionalization with Tyrosine‐Derived Groups
Authors: Neffe Axel Thomas , Zaupa Alessandro , Pierce Benjamin Franklin , Hofmann Dieter , Lendlein Andreas 
Published: August 2010

AbstractMolecular models of gelatin‐based materials formed the basis for the knowledge‐based design of a physically cross‐linked polymer system. The computational models with 25 wt.‐% water content were validated by comparison of the calculated structural properties with experimental data and were then used as predictive tools to study chain organization, cross‐link formation, and estimation of mechanical properties. The introduced tyrosine‐derived side groups, desaminotyrosine (DAT) and desaminotyrosyl tyrosine (DATT), led to the reduction of the residual helical conformation and to the formation of physical net‐points by π–π interactions and hydrogen bonds. At 25 wt.‐% water content, the simulated and experimentally determined mechanical properties were in the same order of magnitude. The degree of swelling in water decreased with increasing the number of inserted aromatic functions, while Young's modulus, elongation at break, and maximum tensile strength increased.magnified image
Estimation of age at death of sika deer (Cervus nippon) from an archaeological site based on radiographs of mandibular molariform tooth development
Authors: Yamazaki T. , Jogahara T. , Koyasu K. , Oda S.‐I. 
Published: August 2010

AbstractThe development of permanent premolar and molar teeth was examined in mandibular radiographs from wild sika deer (Cervus nippon) of known ages (74 males, 66 females, 4 unknown; age range 1–54 months) from Hyogo Prefecture. Tooth development was scored according to the method described by Brown & Chapman (1991a, b). Stage‐specific scores for all molar and premolar teeth were summed, and simple cubic regression analysis was used to analyse the relationship between the total score and age in months. Our analysis showed a strong cubic correlation between the total score and chronological age in months. The equation obtained from this analysis was used to estimate age within a 95% prediction interval in seven archaeological specimens from the Asahi archaeological site in central Japan.

Optimal probing control for wireless transmission when the payload is negligible
Authors: Lin Kyle Y. , Wei Yu‐Feng 
Published: August 2010

AbstractA mobile electronic device needs to periodically connect to a stationary receiver, but the information to transfer is minimal. One such example is the electronic bracelet used in house arrest, where the main purpose is to inform the receiver that the person is in the house. Because the mobile device does not know its current distance from the receiver, it has incentive to first send a low‐strength signal to conserve its battery energy. If the low‐strength signal fails to reach the receiver, the mobile device then gradually increases its signal strength until a successful connection occurs. By formulating the problem as a dynamic program, we characterize the structure of the optimal probing policy and develop an algorithm to compute it. We also consider a discrete approximation that can be easily implemented in practice. Numerical examples show promising improvement of the derived policy over naive heuristic policies, and that the derived policy is robust when there are small errors in estimating the distribution of the distance between the mobile device and the receiver.

AbstractMild testicular heating safely and reversibly suppresses spermatogenesis. In this study, we attempted to clarify the underlying molecular mechanism(s) involved in heat‐induced spermatogenesis suppression in human testis. We conducted global proteomic analyses of human testicular biopsies before, and at 2 and 9 wk after heat treatment. Thirty‐one and Twenty‐six known proteins were identified with significant differential expression at 2 and 9 wk after heat treatment, respectively. These were used to characterize the cellular and molecular events in the testes when seminiferous epithelia became damaged (2 wk) and recovered (9 wk). At 2 wk post‐treatment, the changed expression of a series of proteins could promote apoptosis or suppress proliferation and cell survival. At 9 wk post‐treatment, the changed expression of proteins mainly promoted cell proliferation, differentiation and survival, but resisted cell apoptosis. Among those heat‐regulated proteins, HNRNPH1 was selected for the further functional study. We found that HNRNPH1 was an anti‐apoptosis protein that could regulate the expression of other heat‐induced proteins. In conclusion, heat‐induced reversible suppression of spermatogenesis occurred by modulating the expression of proteins related to proliferation, differentiation, apoptosis and cell survival pathways. These differentially expressed proteins were found to be key molecular targets affecting spermatogenesis after heat treatment.
Combined use of computational chemistry, NMR screening, and X‐ray crystallography for identification and characterization of fluorophilic protein environments
Authors: Vulpetti Anna , Schiering Nikolaus , Dalvit Claudio 
Published: August 2010

Abstract19F NMR screening of fluorinated fragments with different Local Environment of Fluorine, a.k.a. LEF library, is an experimental methodology which, beyond providing useful starting fragments for fragment‐based drug discovery projects, offers, in combination with crystal and computational analysis, an approach for the identification of fluorophilic hot‐spots in the proteins of interest. The application of this approach in the identification of fluorinated fragments binding to the serine protease trypsin, and the X‐ray structures of the complexes are presented. The specific nature of the observed fluorine‐protein interactions is discussed and compared with the interactions detected for other fluorinated ligands reported in the protein data bank. The presence of similar 3D arrangements of protein atoms at the fluorine sub‐sites is identified with a newly developed tool. In this approach, protein sub‐sites are extracted around each fluorine contained in the protein data bank and compared with the query of interest by using a pharmacophoric description.

Authors: Tohidlou Esmaeil , Ganjkhanlou Yadolah , Kazemzad Mahmood , Afarani Mehdi Shafiee 
Published: August 2010

AbstractY2O3:Eu and Y2O3:Eu,Zn nano powders were prepared by both conventional combustion and microwave assistance combustion (MAC) methods. The nanopowders obtained here were investigated by means of X‐ray diffractometry (XRD), Photoluminescence spectroscopy (PL) and scanning electron microscopy (SEM). The chromaticities of samples were also computed from Photoluminescence emission spectra, as well as lattice constant and micro‐structural parameters (crystallite size and micro‐strain) which were computed from XRD patterns using Rietveld refinement method. Results showed that incorporation of Zn in Y2O3:Eu lattice enhanced the PL intensity and chromaticity of Y2O3:Eu phosphor. It was also found that the samples prepared by microwave assistance combustion method had higher crystallinity, density, chromaticity and PL intensity than the samples prepared by conventional combustion method. SEM micrographs showed that the size of particles produced in microwave was smaller than that of samples produced in electric furnace. (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Neuroprotective effects of a sesquiterpene lactone and flavanones from Paulownia tomentosa Steud. against glutamate‐induced neurotoxicity in primary cultured rat cortical cells
Authors: Kim Soo‐Ki , Cho Sang‐Buem , Moon Hyung‐In 
Published: August 2010

AbstractThe neuroprotective effects of Paulownia tomentosa against glutamate‐induced neurotoxicity were studied in primary cultured rat cortical cells. It was found that the aqueous extract of this medicinal plant significantly attenuated glutamate‐induced toxicity. In order to clarify the mechanism(s) underlying this neuroprotective effect, the active fractions and components were isolated and identified. Five compounds were isolated as the methanol extracts from air‐dried flowers of P. tomentosa. Isoatriplicolide tiglate exhibited significant neuroprotective activity against glutamate‐induced toxicity at concentrations ranging from 1 µm to 10 µm, and exhibited cell viability of approximately 43–78%. Therefore, the neuroprotective effect of P. tomentosa might be due to the inhibition of glutamate‐induced toxicity by the sesquiterpene lactone derivative it contains.

Boundary‐layer simulations for the Mars Phoenix lander site
Authors: Savijärvi Hannu , Määttänen Anni 
Published: August 2010

AbstractDiurnal simulations and sensitivity studies were made with a moist column model at the Mars Phoenix lander site (68°N) for the summer solstice (solar day 30) and for a later date (sol 99), when the LIDAR on board Phoenix detected fog, dust, ice clouds and even snowfall from cloud. The sol 30 simulation reproduces the observed repetitive diurnal 2 m temperature cycle quite well, displaying a well‐mixed boundary layer up to 4 km in the afternoon and a strong surface inversion to 500 m each night. Weak frost formation peaks at midnight and a very thin radiation fog appears during the coldest hour. The near‐surface water vapour pressure is underestimated during daytime but is close to the thermal and electrical conductivity probe observations during the night. The Prandtl slope wind mechanism produces veering winds in the model as observed by the ‘telltale’ device while coupled dust evolution implies well‐mixed dust to 4 km throughout the sol as observed by the LIDAR.The colder diurnal conditions around sol 99 are also simulated rather well. In these, the morning fog grows up to 800 m height and a water ice cloud forms at 4 km height at about 0300 local time, as observed. The cloud marks the radiatively cooled top of the moist residual boundary layer. Strong ground frost formation peaks in the evening, having a visible impact on the temperatures. The fog and cloud display weak feedbacks to the modelled radiative fluxes. Copyright © 2010 Royal Meteorological Society
Extension of the cumulant definition for low particle number systems
Authors: Kong Liguo 
Published: August 2010

AbstractCumulants are usually interpreted as the connected components of density matrices, but this interpretation fails and practical problems arise when the rank n of cumulants is larger than the number of particles (N) in the system. In that case, cumulants defined in the traditional way become disconnected. To solve this problem, the definition of cumulants is extended by introducing a simple modulation factor. The modified cumulants reduce to the conventional definition, but they vanish when N < n. Using the modified definition also eliminates the error in the approximation of density matrices by low‐rank cumulants, when N < n. The problem assumes a slightly different form when we work with active space–based theories, and it can be solved by a similar approach. Another problem with cumulants, due to spin coupling [Herbert, Int J Quantum Chem 2007, 107, 703], can be solved via the introduction of a similar modulation factor. A related yet more serious issue, termed as the local particle number constraint problem, is also discussed. © 2010 Wiley Periodicals, Inc. Int J Quantum Chem, 2011
Stability and performance analysis of time‐delay LPV systems with brief instability
Authors: Mohammadpour Javad , Grigoriadis Karolos 
Published: August 2010

AbstractLinear parameter‐varying (LPV) systems provide a systematic framework for the study of nonlinear systems by considering a representative family of linear time‐invariant systems parameterized by system parameters residing in a compact set. Thebrief instabilityconcept in such systems allows the linear system to be unstable for some trajectories of the LPV parameter set, so that instability occurs only for short periods of time. In the present paper, we extend the notion of brief instability to LPV systems with time delay in their dynamics. The results provide tools for the stability and performance analysis of such systems, where performance is evaluated in terms of induced ℒ︁2‐gain (or so‐called ℋ︁∞norm). The main results of this paper illustrate that stability and performance conditions can be evaluated by examining the feasibility of parameterized sets of linear matrix inequalities (LMIs). Using the results of this paper, we then investigate analysis conditions to guarantee the asymptotic stability and ℋ︁∞performance of fault‐tolerant control (FTC) systems, in which instability may take place for a short period of time due to the false identification of the fault signals provided by a fault detection and isolation (FDI) module. The numerical examples are used to illustrate the qualification of the proposed analysis and synthesis results for addressing brief instability in time‐delay systems.

Direct effects testing: A two‐stage procedure to test for effect size and variable importance for correlated binary predictors and a binary response
Authors: Sperrin M. , Jaki T. 
Published: August 2010

AbstractIn applications such as medical statistics and genetics, we encounter situations where a large number of highly correlated predictors explain a response. For example, the response may be a disease indicator and the predictors may be treatment indicators or single nucleotide polymorphisms (SNPs). Constructing a good predictive model in such cases is well studied. Less well understood is how to recover the ‘true sparsity pattern’, that is finding which predictors have direct effects on the response, and indicating the statistical significance of the results. Restricting attention to binary predictors and response, we study the recovery of the true sparsity pattern using a two‐stage method that separates establishing the presence of effects from inferring their exact relationship with the predictors. Simulations and a real data application demonstrate that the method discriminates well between associations and direct effects. Comparisons with lasso‐based methods demonstrate favourable performance of the proposed method. Copyright © 2010 John Wiley & Sons, Ltd.

Published: August 2010

AbstractTrimeric‐type nonionic surfactants based on tris(2‐aminoethyl)amine were prepared. N‐alkyl chloride (namely, octanoyl chloride, n‐decanoyl chloride, n‐dodecanoyl chloride) was reacted with tris(2‐aminoethyl)amine in the presence of toluene and triethylamine. The products were partially reduced and then ethoxylated by poly(ethylene glycol) of molecular weights 400, 1,000, and 2,000 g mol−1. The structures were confirmed by infrared (IR) and 1HNMR spectroscopy. The molecular weights of the surfactants were measured by gel permeation chromatography (GPC). The properties of the prepared compounds were investigated by the surface tension, interfacial tension, and cloud point. The emulsification power of the prepared surfactants for oil‐in‐water emulsions was also studied and the emulsion stability was monitored by an optical microscope and the bottle testing method. Some factors affecting the emulsion stability were investigated

Why did I eat that? Perspectives on food decision making and dietary restraint
Authors: Bublitz Melissa G. , Peracchio Laura A. , Block Lauren G. 
Published: August 2010

AbstractConsumers trying to watch or restrict what they eat face a battle each day as they attempt to navigate the food‐rich environments in which they live. Due to the complexity of food decision making, consumers are susceptible to a wide range of social, cognitive, affective, and environmental forces determined to interrupt their intentions to restrict their dietary intake. In this article, we integrate literature from diverse theoretical perspectives into a conceptual framework designed to offer a better understanding of the antecedents, interruptions, and consequences of dietary restraint. We outline a path for researchers to investigate how restraint behaviors in the eating domain influence a wide variety of consumer psychological phenomena. It is our hope that a collective examination of this literature provides a lens that directs future research on food decision making and dietary restraint and empowers consumers to invest their cognitive and behavioral resources towards healthy eating behaviors.
