Published: August 2013

ABSTRACTAssessing relationships among germplasm and cultivars of Kentucky bluegrass (Poa pratensis L.) is limited to field evaluations or a small set of molecular markers. To improve the efficiency of characterizing Kentucky bluegrass cultivars and germplasm, this study was designed to develop a larger set of robust molecular makers and a concise panel of cultivars to assess relationships of Kentucky bluegrass. An extensive library of simple sequence repeat markers was developed and used to assess relationships among and within 24 cultivars and accessions. Plants generally grouped as cultivars in cluster analysis, but molecular outlying plants and phenotypic off‐type plants were found in 15 of the entries. The cultivars represented the major Kentucky bluegrass classification types and were consistent with previous reports. Salt‐tolerant National Plant Germplasm System accessions were placed in context with the cultivars and grouped closest to the Eurasian/Common type cultivar Kenblue. Similarity of plants within cultivars varied from 60 to 98% but never reached 100%. These data showed that, with two exceptions, the cultivars could represent the major Kentucky bluegrass classification types and also that molecular variation exists within putatively apomictic plants.

ABSTRACT

Objective:
To compare the esthetic preference of White and Chinese judges with regard to Chinese lip position.

Materials and Methods:
The profile images of a dental and skeletal Class I Chinese adult male and female were digitally adjusted to Chinese mean values. The lip profile was adjusted with the upper and lower lip at the mean distance from the Ricketts' E-line. These images were used as baseline images and were further digitally manipulated to generate six additional images with the upper and lower lip such that they lay 0.5, 1.0, and 2.0 standard deviations (SDs) in front of or behind the E-line. An additional image was modified based on a White mean value. The images were viewed and ranked by 251 White and Chinese judges (dentists and laypersons) in Australia and China.

Results:
Significantly more Chinese judges ranked the retrusive profiles higher than the White judges. The White judges also ranked the profile image adjusted to −0.5 SD as the most esthetic for both the female and male, while the Chinese judges ranked the −1.0 SD profile as the most esthetic.

Conclusions:
The ethnicity of the judges is a significant factor influencing the perception of esthetic lip position. The Chinese judges prefer a more retrusive profile and are more likely to rate a protrusive profile as unacceptable, compared with the White judges.

Abstract
Representations of young teenagers and adolescents (not yet young adults) in popular culture are problematic. All too often the term teenager is less about age and experience and more about consumer merchandise and lifestyles aimed at them as a demographic sector. This paper addresses some of the issues and myths that writers and film makers are confronted with when producing teenage culture - everything may not be as you think.
Taking Collaborative Stances to Tell the Story. A Socio-linguistic Approach to Nick Hornby’s A Long Way Down
Authors: Vasiloiu Dorina-Daniela 
Published: August 2013

Abstract
In the present study, I seek to examine narrative in consideration of three of its most important dimensions: the social (others’ narratives), the cognitive (acquisition of knowledge through stories), and the linguistic (acquiring and producing knowledge through language). There is no point of contention that ‘narrative’ is essentially communicative and dependent on a sociolinguistic and cultural context. Yet, with regard to fictional narratives, recent studies on text processing challenge the view of text as communication in its conventional sense. I explore the way(s) in which fictional worlds communicate from the constructivist standpoint and set out to develop the notion of narratorial stance. I then make use of the concept in the close reading section of the paper in order to examine and exemplify the modes in which Hornby’s homodiegetic narrators represent themselves and the others in their ‘turn-at-talk’ or stance-taking acts

Abstract
The present paper is focused on the study of the thermal behavior of casein, the main protein in milk, by applying the TG-FTIR technique and calorimetric measurements. The research is of a great interest due to the large application areas of casein in cosmetic, food and pharmaceutical industries. The analysis of the thermal behavior by the TG-DTG-DTA methods allwos the finding of the temperature range where the casein is thermally stable and the caseincontaining cosmetics, food and pharmaceutical products proper for using. The identification of the gaseous species released allwos the TG-FTIR coupled technique to give useful information on the possible environmental impact when the casein-containing products are used at temperatures above the casein initial degradation temperature. The combustion heat of casein estimated by means of the Berthelot calorimeter made evident this value to be close to those of the most important and used fuels which would recommend the waste casein-containing products to be used as fuels.
3-Methylpiperidinyl Carbodithioates as Building Blocks for 1,3-Dithiolium Derivatives
Authors: Sarbu Laura G. , Bahrin Lucian G. 
Published: August 2013

Abstract
New 1,3-dithiolium derivatives have been synthesized by heterocyclocondensation of various 3-methylpiperidinyl carbodithioates derived from 2-hydroxypropiophenones. Thus, 1,3-dithiolium perchlorates have been obtained by the treatment of the corresponding dithiocarbamates with a mixture of acetic and sulfuric acid, followed by the addition of perchloric acid. 1,3-Dithiolium perchlorates have been converted to the corresponding 2-(1,3-dithiolium) phenolates under weak basic conditions. These phenolates exhibit mesoionic character with an internal charge transfer absorption band.
Characterizations of ɛ-duality gap statements for constrained optimization problems
Authors: Boncea Horaţiu-Vasile , Grad Sorin-Mihai 
Published: August 2013

Abstract
In this paper we present different regularity conditions that equivalently characterize various ɛ-duality gap statements (with ɛ ≥ 0) for constrained optimization problems and their Lagrange and Fenchel-Lagrange duals in separated locally convex spaces, respectively. These regularity conditions are formulated by using epigraphs and ɛ-subdifferentials. When ɛ = 0 we rediscover recent results on stable strong and total duality and zero duality gap from the literature.
Effect of experimental top soil removal on vegetation of Pannonian salt steppes
Authors: Melečková Zuzana , Galvánek Dobromil , Dítě Daniel , Eliáš Pavol 
Published: August 2013

AbstractInland saline habitats of the Pannonian Lowland exhibit a specific variety of grasslands determined by a soil salinity gradient. Changes in the hydrological regime and absence of management have resulted in heavy degradation of the vegetation. The impact of topsoil removal on salt steppes was tested by a 3-year small-scale manipulated experiment in SW Slovakia (Kamenínske Slanisko Nature Reserve). Topsoil was removed in three contrasting types of vegetation with different soil salinities, i.e. in different stages of habitat degradation. Data were analysed by multi-way ANOVA and by multivariate methods. Species richness decreased and the proportion of halophytes increased significantly in the two types with the highest soil salinity; however, the total number of halophytes was not influenced by soil removal. The treatment caused inhibition of secondary succession on the plots with the highest salinity. The effect of the soil removal was only short-term in the vegetation with moderate salinity and on heavily degraded and desalinized types it even stimulated further recruitment of ruderal species. Topsoil removal has only limited potential for the restoration of Pannonian salt steppes. It should be applied only in slightly degraded vegetation, where salt accumulation is still present and target species propagules are available.

Published: August 2013

AbstractCertain physical and mechanical phenomena within ultra-thin face-centered cubic (fcc) films containing common types of interacting point defects are addressed. An atomic-scale lattice statics in conjunction with many-body interatomic potentials suitable for binary systems is conducted to analyze the effects of the depth on the: (1) formation energy and layer-by-layer displacements due to the presence of vacancy-octahedral self-interstitial atom (OSIA) ensemble, and (2) elastic fields as well as the free surface shape in the case of vacancy-dopant interaction. Moreover, the effects of the inter-defect spacing for various depths are also examined. To ensure reasonable accuracy and numerical convergence, the atomic interaction up to the second-nearest neighbor is considered.
Soliton-like solutions to the generalized Burgers-Huxley equation with variable coefficients
Authors: Triki Houria , Wazwaz Abdul-Majid 
Published: August 2013

AbstractIn this paper, we consider the generalized Burgers-Huxley equation with arbitrary power of nonlinearity and timedependent coefficients. We analyze the traveling wave problem and explicitly find new soliton-like solutions for this extended equation by using the ansatz of Zhao et al. [X. Zhao, D. Tang, L. Wang, Phys. Lett. A 346 (2005) 288–291]. We also employ the solitary wave ansatz method to derive the exact bright and dark soliton solutions for the considered evolution equation. The physical parameters in the soliton solutions are obtained as function of the time-dependent model coefficients. The conditions of existence of solitons are presented. As a result, rich exact travelling wave solutions, which contain new soliton-like solutions, bell-shaped solitons and kink-shaped solitons for the generalized Burgers-Huxley equation with time-dependent coefficients, are obtained. The methods employed here can also be used to solve a large class of nonlinear evolution equations with variable coefficients.
Toward an accurate taxonomic interpretation ofCarexfossil fruits (Cyperaceae): A case study in sectionPhacocystisin the Western Palearctic
Authors: Jiménez‐Mejías Pedro , Martinetto Edoardo 
Published: August 2013

•Premise of the Study:Despite growing interest in the systematics and evolution of the hyperdiverse genusCarex, few studies have focused on its evolution using an absolute time framework. This is partly due to the limited knowledge of the fossil record. However,Carexfruits are not rare in certain sediments. We analyzed carpological features of modern materials fromCarexsect.Phacocystisto characterize the fossil record taxonomically.•Methods:We studied 374 achenes from modern materials (18 extant species), as well as representatives from related groups, to establish the main traits within and among species. We also studied 99 achenes from sediments of living populations to assess their modification process after decay. Additionally, we characterized 145 fossil achenes from 10 different locations (from 4–0.02 mya), whose taxonomic assignment we discuss.•Key Results:Five main characters were identified for establishing morphological groups of species (epidermis morphology, achene–utricle attachment, achene base, style robustness, and pericarp section). Eleven additional characters allowed the discrimination at species level of most of the taxa. Fossil samples were assigned to two extant species and one unknown, possibly extinct species.•Conclusions:The analysis of fruit characters allows the distinction of groups, even up to species level. Carpology is revealed as an accurate tool inCarexpaleotaxonomy, which could allow the characterization ofCarexfossil fruits and assign them to subgeneric or sectional categories, or to certain species. Our conclusions could be crucial for including a temporal framework in the study of the evolution ofCarex.

Abstract
IgA plays ambivalent roles in the immune system. The balance between inhibitory and activating responses relies on the multimerization status of IgA and interaction with their cognate receptors. In mucosal sites, secretory IgA (SIgA) protects the host through immune-exclusion mechanisms, but its function in the bloodstream remains unknown. Using bone marrow–derived dendritic cells, we found that both human and mouse SIgA induce tolerogenic dendritic cells (DCs) following binding to specific ICAM-3 grabbing nonintegrin receptor 1. This interaction was dependent on Ca2+ and mannose residues. SIgA-primed DCs (SIgA-DCs) are resistant to TLR-dependent maturation. Although SIgA-DCs fail to induce efficient proliferation and Th1 differentiation of naive responder T cells, they generate the expansion of regulatory T cells through IL-10 production. SIgA-DCs are highly potent in inhibiting autoimmune responses in mouse models of type 1 diabetes and multiple sclerosis. This discovery may offer new insights about mucosal-derived DC immunoregulation through SIgA opening new therapeutic approaches to autoimmune diseases.

ABSTRACTA 51-year-old male presented to the ENT outpatient department with complaints of pain, irritation and foreign body sensation in the throat for 3 months. There was history of being diagnosed to have laryngeal paraganglioma for which the patient had undergone microlaryngeal surgical excision twice during the preceding 9 years. Clinical examination revealed a reddish proliferative mass of about 2 cm involving the laryngeal surface of the epiglottis and extending to the right aryepiglottic fold. Vocal cords were normal in structure and function.With the previous history of endolaryngeal excision of the tumor and its recurrence, the patient underwent laryngofissure approach with median thyrotomy and left lateral pharyngotomy. The tumor was excised in toto and histopathologically confirmed as paraganglioma. Postoperative period was uneventful. Patient is on continued follow-up with no recurrence till date.How to cite this articleSamuel J, Mohanty S, Maraignanam G. Surgical Management of Recurrent Laryngeal Glomus.

Published: August 2013

ABSTRACT
Here we report a rare case, for this era, of supraglottic laryngitis with abscess formation after antibiotics use. Laryngeal ultrasound for abscess detection and follow-up has advantages over neck computed tomography. This modality can assess vocal cord movement noninvasively with the benefits of cost effectiveness, easy availability, freedom from radiation, and high resolution-factors that are superior to other modalities. Although laryngeal abscesses are rare, clinicians should be aware of their myriad presentations. Acute supraglottitis with abscess formation may cause potentially fatal obstruction of the airway. Early recognition and intervention to prevent morbidity and mortality is thus very important.

Abstract
Patient-specific induced pluripotent stem cells (iPSCs) hold great promise for studies on disease-related developmental processes and may serve as an autologous cell source for future treatment of many hereditary diseases. New genetic engineering tools such as zinc finger nucleases and transcription activator-like effector nuclease allow targeted correction of monogenetic disorders but are very cumbersome to establish. Aiming at studies on the knockdown of a disease-causing gene, lentiviral vector-mediated expression of short hairpin RNAs (shRNAs) is a valuable option, but it is limited by silencing of the knockdown construct upon epigenetic remodeling during differentiation. Here, we propose an approach for the expression of a therapeutic shRNA in disease-specific iPSCs using third-generation lentiviral vectors. Targeting severe α-1-antitrypsin (A1AT) deficiency, we overexpressed a human microRNA 30 (miR30)-styled shRNA directed against the PiZ variant of A1AT, which is known to cause chronic liver damage in affected patients. This knockdown cassette is traceable from clonal iPSC lines to differentiated hepatic progeny via an enhanced green fluorescence protein reporter expressed from the same RNA-polymerase II promoter. Importantly, the cytomegalovirus i/e enhancer chicken β actin (CAG) promoter-driven expression of this construct is sustained without transgene silencing during hepatic differentiation in vitro and in vivo. At low lentiviral copy numbers per genome we confirmed a functional relevant reduction (−66%) of intracellular PiZ protein in hepatic cells after differentiation of patient-specific iPSCs. In conclusion, we have demonstrated that lentiviral vector-mediated expression of shRNAs can be efficiently used to knock down and functionally evaluate disease-related genes in patient-specific iPSCs.

Abstract
Glioblastoma multiforme (GBM) remains fatal despite intensive surgical, radiotherapeutic, and chemotherapeutic interventions. Neural stem cells (NSCs) have been used as cellular vehicles for the transportation of oncolytic virus (OV) to therapeutically resistant and infiltrative tumor burdens throughout the brain. The HB1.F3-CD human NSC line has demonstrated efficacy as a cell carrier for the delivery of a glioma tropic OV CRAd-Survivin-pk7 (CRAd-S-pk7) in vitro and in animal models of glioma. At this juncture, no study has investigated the effectiveness of OV-loaded NSCs when applied in conjunction with the standard of care for GBM treatment, and therefore this study was designed to fill this void. Here, we show that CRAd-S-pk7-loaded HB1.F3-CD cells retain their tumor-tropic properties and capacity to function as in situ viral manufacturers in the presence of ionizing radiation (XRT) and temozolomide (TMZ). Furthermore, for the first time, we establish a logical experimental model that aims to recapitulate the complex clinical scenario for the treatment of GBM and tests the compatibility of NSCs loaded with OV. We report that applying OV-loaded NSCs together with XRT and TMZ can increase the median survival of glioma bearing mice by approximately 46%. Most importantly, the timing and order of therapeutic implementation impact therapeutic outcome. When OV-loaded NSCs are delivered prior to rather than after XRT and TMZ treatment, the median survival of mice bearing patient-derived GBM43 glioma xenografts is extended by 30%. Together, data from this report support the testing of CRAd-S-pk7-loaded HB1.F3-CD cells in the clinical setting and argue in favor of a multimodality approach for the treatment of patients with GBM.
