A NEW NONPLANETARY INTERPRETATION OF THE MICROLENSING EVENT OGLE-2013-BLG-0723
Authors: Han Cheongho , Bennett David P. , Udalski Andrzej , Jung Youn Kil
Published: June 2016

Recently, the discovery of a Venus-mass planet orbiting a brown-dwarf host in a binary system was reported from the analysis of the microlensing event OGLE-2013-BLG-0723. We reanalyze the event considering the possibility of other interpretations. From this, we find a new solution where the lens is composed of two bodies, in contrast to the three-body solution of the previous analysis. The new solution better explains the observed light curve than the previous solution with Δχ
2 ∼ 202, suggesting that the new solution is a correct model for the event. From the estimation of the physical parameters based on the new interpretation, we find that the lens system is composed of two low-mass stars with ∼0.2 M
⊙ and ∼0.1 M
⊙ and located at a distance of ∼3 kpc. The fact that the physical parameters correspond to those of the most common lens population located at a distance with a large lensing probability further supports the likelihood of the new interpretation. Considering that two dramatically different solutions can approximately explain the observed light curve, the event suggests the need for carefully testing all possible lens-system geometries.

Published: June 2016

Unaccounted for systematics from foregrounds and instruments can severely limit the sensitivity of current experiments from detecting redshifted 21 cm signals from the Epoch of Reionization (EoR). Upcoming experiments are faced with a challenge to deliver more collecting area per antenna element without degrading the data with systematics. This paper and its companions show that dishes are viable for achieving this balance using the Hydrogen Epoch of Reionization Array (HERA) as an example. Here, we specifically identify spectral systematics associated with the antenna power pattern as a significant detriment to all EoR experiments which causes the already bright foreground power to leak well beyond ideal limits and contaminate the otherwise clean EoR signal modes. A primary source of this chromaticity is reflections in the antenna-feed assembly and between structures in neighboring antennas. Using precise foreground simulations taking wide-field effects into account, we provide a generic framework to set cosmologically motivated design specifications on these reflections to prevent further EoR signal degradation. We show that HERA will not be impeded by such spectral systematics and demonstrate that even in a conservative scenario that does not perform removal of foregrounds, HERA will detect the EoR signal in line-of-sight k-modes,

Mpc−1, with high significance. Under these conditions, all baselines in a 19-element HERA layout are capable of detecting EoR over a substantial observing window on the sky.
Determinants of Virological Response to Antiretroviral Therapy: Socio-Economic Status Still Plays a Role in the Era of cART. Results from the ANRS-VESPA 2 Study, France
Authors: D'Almeida Kayigan W , Lert France , Spire Bruno , Dray-Spira Rosemary
Published: June 2016

Background

Disparities in combined antiretroviral therapy (cART) outcomes have been consistently reported among people living with HIV (PLWHIV). The present study aims at investigating the mechanisms underlying those disparities among PLWHIV in France.

Methods

We used data from the Vespa2 survey, a large national cross-sectional survey, representative of HIV-infected people followed at hospitals in 2011. Among participants diagnosed ≥1996, HIV treatment-naive at the time of cART initiation and on cART for at least 12 months, the frequency of sustained virological suppression (SVS; undetectable viral load [<50 copies/ml] for at least 6 months) at the time of the survey, was assessed and its social determinants were measured through logistic regression, accounting for clinical and biological determinants of response to cART.

Results

Among 1,246 participants, 77.7% had achieved SVS. SVS was less frequent among those unemployed (0.6 [range 0.3-1.0]) and those with the lowest level of education (0.4 [range 0.2-0.9]). The late presenters, diagnosed at a CD4+ T-cell count <200/mm3 (0.5 [range 0.3-0.9]) and the late starters, diagnosed at a CD4+ T-cell count >200 but initiating cART at CD4+ T-cell count <200 (0.3 [range 0.1-0.8]) were less likely than the ideal starters (≥350 CD4+ T-cells/mm3 at cART initiation) to achieve SVS, as were those who reported suboptimal adherence versus those reporting optimal adherence (0.4 [range 0.2-0.7]). In bivariate analyses, material deprivation, discrimination and a weak social network were also associated with a poorer treatment response.

Conclusions

Structural social factors remain strong determinants of treatment response and should be addressed in a broad approach of care, but wider political issues should also be investigated.
The Role of Levosimendan in Patients with Decreased Left Ventricular Function Undergoing Cardiac Surgery
Authors: Bozhinovska Marija , Taleska Gordana , Fabian Andrej , Å oÅ¡tariÄ Maja
Published: June 2016

The postoperative low cardiac output is one of the most important complications following cardiac surgery and is associated with increased morbidity and mortality. The condition requires inotropic support to achieve adequate hemodynamic status and tissue perfusion. While catecholamines are utilised as a standard therapy in cardiac surgery, their use is limited due to increased oxygen consumption. Levosimendan is calcium sensitising inodilatator expressing positive inotropic effect by binding with cardiac troponin C without increasing oxygen demand. Furthermore, the drug opens potassium ATP (KATP) channels in cardiac mitochondria and in the vascular muscle cells, showing cardioprotective and vasodilator properties, respectively. In the past decade, levosimendan demonstrated promising results in treating patients with reduced left ventricular function when administered in peri- or post- operative settings. In addition, pre-operative use of levosimendan in patients with severely reduced left ventricular ejection fraction may reduce the requirements for postoperative inotropic support, mechanical support, duration of intensive care unit stay as well as hospital stay and a decrease in post-operative mortality. However, larger studies are needed to clarify clinical advantages of levosimendan versus conventional inotropes.
La résonance du rêve dans la psychanalyse de couple
Authors: Lito Ana Marques
Published: June 2016

Cet article a pour but de démontrer l’importance de la résonance symbolique du rêve dans le processus transférentiel et contretransférentiel de la psychanalyse de couple. Il traite également du processus intermédiaire mettant à jour l’impact de l’histoire familiale dans la vie actuelle. L’interprétation de l’analyste et les reconstructions narcissique-identitaires des patients qui surviennent dans un processus inconscient évolutif en O, facilitent une position d’ouverture existentielle et un cadre de représentations communes aux conjoints et à l’analyste. La psychanalyse d’un couple ayant duré 3 ans et demi de travail régulier tous les quinze jours illustre les dynamiques groupales en cours. Le processus voit apparaître une réaction thérapeutique négative. Les conjoints ont formé une « famille de verre » selon les propositions de l’auteur.

Published: June 2016

Les auteurs proposent à travers l’étude d’un cas clinique d’envisager le symptôme obésité en interrogeant les enjeux psychiques de la migration. Ils envisagent ainsi que cette clinique de l’exil constitue un trauma dans la sphère familiale poussant le groupe à investir le corps de l’un d’eux comme pour témoigner d’une souffrance collective indicible. C’est à travers l’étude de productions graphiques telles que le dessin libre de l’arbre généalogique et le dessin familial de la maison de rêve qu’ils proposent une interprétation de ce qui n’a pu être symbolisé. C’est également l’occasion pour les auteurs de proposer des aménagements possibles en termes de pistes thérapeutiques afin de dégager ces familles de leur souffrance.
Understanding the drying kinetic and hygroscopic behaviour of larvae of yellow mealworm (Tenebrio molitor) and the effects on their quality
Authors: Azzollini D. , Derossi A. , Severini C.
Published: June 2016

The use of insects for preparing high nutritional value foods is emerging. The dehydration kinetic of yellow mealworms larvae and its hygroscopic behaviour were described also analysing the changes in quality attributes. Blanching was performed before air drying at 50, 60 and 70 °C while sorption isotherms were studied after air drying and freeze-drying. The Page model described the dehydration kinetic at 50, 60 and 70 °C with a coefficient of determination of 0.993. Moisture diffusion coefficients between 4.85×10-11 and 1.62×10-10 m2/s were estimated and their temperature dependence was described by the Arrhenius equation, estimating an Ea of 52.1 kJ/mol. The Guggenheim-Anderson-de Boer model well fitted experimental data, showing isotherms of type II and estimating a monolayer value of 0.05 g H2O/g dry matter. Blanching significantly modified the adsorption isotherms, increased the moisture of fresh larvae without affecting their proximate composition. Rehydration after lyophilisation produced higher colour degradation probably due to the increase of enzymatic activity.

Ways of Being: Preparing Nursing Students for Transition to Professional Practice
Authors: Mellor Peter , Gregoric Carolyn
Published: June 2016

Background:

The new graduate registered nurse (NGRN) does not work in isolation but within an organizational environment. Unfortunately for the NGRN, transition-to-practice programs are often variable and underresourced, which means that promised support is unlikely to eventuate. Many NGRNs learn the skills required to navigate the nursing culture on the job without support and by trial and error.

Method:

A grounded theory method was used to identify the strategies used by nine NGRNs to thrive during their transition to professional practice.

Results:

Ways of being emerged from the data to explain the social and emotional strategies NGRNs use during the first year of practice. The ways of being model includes ways of feeling, ways of relating, and ways of doing.

Conclusion:

University preparation needs to ensure that the NGRN is provided with the skills to successfully navigate the workplace. Use of the ways of being model could help achieve this.

Concept-Based Learning in Clinical Experiences: Bringing Theory to Clinical Education for Deep Learning
Authors: Nielsen Ann
Published: June 2016

Background:

Concept-based learning is used increasingly in nursing education to support the organization, transfer, and retention of knowledge. Concept-based learning activities (CBLAs) have been used in clinical education to explore key aspects of the patient situation and principles of nursing care, without responsibility for total patient care. The nature of best practices in teaching and the resultant learning are not well understood.

Method:

The purpose of this multiple-case study research was to explore and describe concept-based learning in the context of clinical education in inpatient settings. Four clinical groups (each a case) were observed while they used CBLAs in the clinical setting.

Results:

Major findings include that concept-based learning fosters deep learning, connection of theory with practice, and clinical judgment. Strategies used to support learning, major teaching–learning foci, and preconditions for concept-based teaching and learning will be described.

Conclusion:

Concept-based learning is promising to support integration of theory with practice and clinical judgment through application experiences with patients. [

Authors: Giddens Jean L. , Meyer Donna
Published: June 2016

Background:

The Institute of Medicine recommendation for a more educated nursing workforce has triggered significant activity in the area of academic profession, particularly in pre- and postlicensure baccalaureate nursing education. Many innovative academic progression models involving universities and community colleges have emerged. Among the most common barriers to this effort are inconsistent prerequisite course requirements.

Method:

A workgroup convened to discuss commonalities and differences of general education and prerequisite course work and propose core prerequisite coursework for the baccalaureate nursing degree.

Results:

A course menu strategy for foundational baccalaureate nursing courses was proposed that includes four general course categories with credit ranges and common courses or content for each category. The four proposed foundational course categories are general education, basic sciences, social sciences, and human sciences.

Conclusion:

A need exists to reduce barriers affecting academic progression. The foundational course approach proposed has potential to reduce some of these barriers. [

Constructing an Ethical Training for Advanced Nursing Practice: An Interactionist and Competency-Based Approach
Authors: Pariseau-Legault Pierre , Lallier Melisa
Published: June 2016

Background:

Advanced practice nurses are working in a highly interdisciplinary and political context. Such situations can influence the deliberative and ethical decision-making processes in which they are also involved. This can subsequently compromise their abilities to protect their moral integrity, to find innovative and nondualistic solutions to complex ethical problems, and to collaborate with other health professionals.

Method:

The authors constructed a training program inspired by discourse and narrative ethics. The objective pursued was to develop advanced practice nurses' moral integrity, highlight the ethical component of their clinical judgement, and foster the development of their deliberative competencies.

Results:

The pedagogical process proposed exposes how an ethical curriculum adapted to the context in which advanced practice nurses evolve can address power relationships inherent in ethical decision making.

Conclusion:

The authors suggest that this pedagogical approach has the potential to optimize the consolidation of ethical, reflective, and deliberative competencies among advanced practice nurses. [

Use of Smartphones With Undergraduate Nursing Students
Authors: George Tracy P. , DeCristofaro Claire
Published: June 2016

Background:

It is important for nursing students to become comfortable with accessing point-of-care technology to support provision of safe, evidence-based care to patients.

Method:

Smartphone applications (apps) were introduced into community screening settings in a first-semester undergraduate nursing health assessment course. The apps provided information about body mass index, as well as United States Preventive Services Task Force–recommended preventive services using the Agency for Health Research and Quality electronic preventive services selector app. Classroom activities prepared students using mock cases and real data, and evidence-based guidelines were used when counseling patients about individual results.

Results:

Smartphone apps were well accepted by students and allowed students to transfer learning from the classroom and laboratory to the community setting.

Conclusion:

Smartphone apps promote active learning and the long-term retention of knowledge. This community-based activity supports the validity of independent health promotion activities in nursing practice. [

Published: June 2016

We have studied the phycological diversity at the Natural Park of Serra da Enciña da Lastra (Ourense, Spain) and present here the algae checklist of the Galir river, the only permanent fluvial course in the area. This geographical zone is a SCI (Site of Community Importance) and is located within an European Nature Reserve belonging to the “Nature 2000” network. Despite its environmental importance there is no previous phycological survey to this study. We collected samples in three points along the river, and measured physical and chemical water parameters (pH, conductivity, temperature, and dissolved oxygen). The checklist includes 88 taxa: 6 Cyanophyta, 4 Rhodophyta, 60 Heterokontophyta (58 Bacillariophyceae, 2 Xantophyceae), 1 Dinophyta, 2 Euglenophyta, and 15 Chlorophyta. Within the Rhodophyta we highlight the presence of Lemanea condensata, as a new record to the Iberian Peninsula. In addition, we have identified 8 new records for Galicia and 14 for Ourense.

Capsules for self-healing concrete have to possess multifunctional properties and it would be an enormous advantage in the valorization process when they could also be mixed in. Therefore, we aimed to develop capsules with evolving brittleness.
Capsules with high initial flexibility were prepared by adding a plasticizer to an ethyl cellulose matrix. During hardening of the concrete, the plasticizing agent should leach out to the moist environment yielding more brittle capsules which break upon crack appearance.
The tested capsules could easily be mixed in during concrete production. However, incompatibility issues between the capsule wall and the inner polymeric healing agent appeared. Moreover, the capsules became insufficiently brittle and the bond strength to the cementitious matrix was too weak.
Consequently, multilayer capsules were tested. These capsules had a high impact resistance to endure concrete mixing and were able to break upon crack formation.

In the globalized world, possessing good products may not be enough to reach potential clients unless creative marketing strategies are well delineated. In this context, public relations are also important when it comes to capture the client's attention, making the first contact between the clients and the company's products, while being persuasive enough to make them confident that the company has the right products to fit their needs. Three virtual public relations installations were purposed in this chapter, combining technology with a human like public relations ability, capable of interacting with potential clients located in front of the installation, at angles of up to 57º (degrees), 180º and 360º, respectively. From one to several Microsoft Kinects were used to develop the three interaction models, which allows tracking and recognition of users' gestures and positions (heat map), sound sources, voice commands and face and body extraction of the user interacting with the installation.
Multimodality Medical Image Fusion Using M-Band Wavelet and Daubechies Complex Wavelet Transform for Radiation Therapy
Authors: Chavan Satishkumar S. , Talbar Sanjay N.
Published: June 2016

The process of enriching the important details from various modality medical images by combining them into single image is called multimodality medical image fusion. It aids physicians in terms of better visualization, more accurate diagnosis and appropriate treatment plan for the cancer patient. The combined fused image is the result of merging of anatomical and physiological variations. It allows accurate localization of cancer tissues and more helpful for estimation of target volume for radiation. The details from both modalities (CT and MRI) are extracted in frequency domain by applying various transforms and combined them using variety of fusion rules to achieve the best quality of images. The performance and effectiveness of each transform on fusion results is evaluated subjectively as well as objectively. The fused images by algorithms in which feature extraction is achieved by M-Band Wavelet Transform and Daubechies Complex Wavelet Transform are superior over other frequency domain algorithms as per subjective and objective analysis.
My Desired Self, Avatar
Authors: Kim Youjeong
Published: June 2016

In computer-mediated communication (CMC) environments, users utilize their avatars as a communication channel to interact and connect with others, and they choose and create them accordingly to represent their self. As such, several major question areas arise: 1) As an extension of identity, how does a user customize his/her avatar? How is the avatar's appearance related to the avatar creator's self-concept? 2) How does avatar creation influence the avatar creator's psychological and behavioral consequences? To answer these questions, the current study leveraged a Korean social networking site, which currently provides avatars called “Minimis,” in a randomized experimental setting. This study found that the more the participants perceived their avatars to look like their desired selves, the more likely they evaluated their avatars as being attractive, credible, confident, cool, capable, and persuasive, but failed to find a significant relationship between avatar users' perceptions toward self-created avatars and their attitudes toward the social network site or ads.. The limitations and implications will be discussed.

Molecular docking was earlier considered to predict the binding affinity of the receptor and ligand molecules. With the progress in computational power and developing approaches, new horizons are now opening for accurate prediction of molecular binding affinity. In the current book chapter, recent strategies for Computer-Aided Drug Designing (CADD) including virtual screening and molecular docking, encompassing molecular dynamics simulations, and binding free energy calculation methods are discussed. Brief overview of different binding free energy methods MMPBSA, MMGBSA, LIE and TI have also been given along with the recent Relaxed Complex Scheme protocol.
Methods for Docking and Drug Designing
Authors: Naqvi Ahmad Abu Turab , Hassan Md. Imtaiyaz
Published: June 2016

Molecular docking is the prediction of conformational complementarity between ligand and receptor molecule. The process of docking integrates two schematic approaches namely sampling of ligand conformations and ranking of selected conformations based on scoring functions. The authors have discussed established methodologies for molecular docking and well-known tools implementing these methods. A brief account of different classes of scoring functions such as force field based, empirical, knowledge based, and descriptor based scoring functions is given along with the exemplary implementations of these scoring functions. By replacing test and trial based ligand screening with structure based virtual screening, molecular docking has helped in shortening the duration of novel drug discovery up to some extent. However, the developments made in the field of drug discovery are assisted by the advances in the techniques of molecular docking, but there is strong need of enrichment in the techniques, especially in scoring functions, to tackle the inbound problems of de novo drug discovery.
Basic Visual Cryptography Using Braille
Authors: Wang Guangyu , Liu Feng , Yan Wei Qi
Published: June 2016

As a significant part of information security, Visual Cryptography (VC) is a secret sharing approach which has the advantage of effectively obscuring hints of original secret. In VC, a secret image is separated into partitions which are also known as VC shares. The secret is only able to be revealed by superimposing certain shares. Since Basic VC is in a structure which is similar to that of Braille where white and black dots are arranged in certain orders, it is feasible to utilize the feature of Braille for the authentication of VC. In this paper, the authors will conduct an experiment embedding Braille into grayscale and halftone images as well as VC shares. The result indicates that the embedding of Braille has little impact on VC secret revealing and enhances the security of VC shares.

Objetivando avaliar sistemas seqüenciais de manejo em semeadura atrasada da soja, Glycine max (L.) Merril (Leguminosae-Faboideae), em condição de estiagem e sua influência sobre o controle de fomesafen, conduziu-se este experimento em São João do Ivaí, Estado do Paraná (1998/99), utilizando-se: (M1) sulfosate + 2,4-D/sulfosate; (M2) sulfosate + 2,4-D/(paraquat+diquat); (M3) sulfosate/(paraquat+diuron); (M4) sulfosate/diquat; (M5) sulfosate/(paraquat+diquat), sendo M1 desenvolvido 26 dias antes da semeadura (DAS) e na semeadura, e os demais sistemas aos 40 DAS e na semeadura. A antecipação do manejo (40 DAS) permitiu redução no uso de herbicidas e melhor controle de Commelina benghalensis. Fomesafen (125 g i.a./ha), aos 19 dias depois da semeadura (DDS), viabilizou sistemas seqüenciais de manejo que atingiram elevados níveis de controle, sendo a sua seqüencial (19 DDS/ 27 DDS) satisfatória, mesmo quando o manejo não foi eficiente. M1 foi deficiente no controle de C. benghalensis, possibilitando substituir 2,4-D por seqüenciais de sulfosate/diquat ou sulfosate/(paraquat+diuron), tanto para Ipomoea grandifolia como para C. benghalensis

Existem muitos compostos extraídos de plantas, denominados aleloquímicos, que alteram a biologia e o compotamento dos insetos. Entre essas substâncias os terpenóides são eficientes inibidores do crescimento larval, reprodução e alimentação. Esse trabalho, realizado na Universidade Estadual Paulista, Botucatu, Estado de São Paulo, procurou verificar a bioatividade do óleo essencial da citronela, Cymbopogon winterianus Jowitt (Poaceae) (rico em citronelal e citronelol) sobre Spodoptera frugiperda. Foram realizados dois bioensaios. No primeiro, folhas de milho com 10 cm de comprimento e 4 cm de largura foram divididas em 3 partes iguais. Uma das partes de uma das extremidades foi mergulhada em soluções contendo 1,0, 0,5, 0,1, 0,05, 0,01, 0,005 e 0,001% de óleo essencial de citronella com 0,05% do emulsificante Tween 20, a outra parte foi mergulhada em água com 0.05% desse emulsificante. Quatro larvas recém-eclodidas foram colocadas no centro de cada folha. No segundo ensaio, superfícies de vidro (placas de Petri) foram tratadas com soluções contendo 1,0, 0,5, 0,1, 0,05 % do óleo essencial de citronela e 0,05% do emulsificante Tween 20, mais um tratamento testemunha (água com 0,05% emulsificante). Após a secagem da superfície, foram colocadas em cada placa de vidro, 10 lagartas recém-eclodidas e cobertas com filme plástico. Os resultados mostraram que o óleo essencial de citronela apresenta ação inseticida e de repelência para lagartas de S. frugiperda.

Published: June 2016

O presente trabalho teve como objetivo determinar o potencial de redução de temperatura do ar por meio de sistemas de resfriamento adiabático evaporativo para a região de Maringá, Estado do Paraná. Foram utilizados dados de 13 anos da Estação Climatológica Principal de Maringá. Relacionou-se a temperatura ambiente, umidade relativa e potencial de redução de temperatura por meios evaporativos. Através dos resultados obtidos, foi possível depreender que, os meses que apresentam maior potencial de redução de temperatura foram: agosto, setembro, outubro e novembro, devido aos baixos valores de umidade relativa do ar. Os meses de dezembro, janeiro, fevereiro e março, apesar de se situarem no verão, apresentaram menor potencial de redução de temperatura por meio de resfriamento adiabático evaporativo, devido à incidência de maiores valores de umidade relativa do ar. Entretanto, pelos valores analisados, conclui-se que esta técnica (resfriamento adiabático) apresenta-se promissora para os horários mais críticos (13h00min às 18h00min), com maior temperatura do ar

Published: June 2016

Infantile hemangiomas (IH) complicated by ulceration, disfigurement, functional impairment or life-threatening conditions need early, safe and effective treatment. This study explores the impact of propranolol on complicated IH. We report our experience of 62 patients treated with oral propranolol for complicated IH. The effect of propranolol was assessed using a score on a visual analogue scale integrated with echo, magnetic resonance or endoscopic findings. The average age at the beginning of the treatment was seven months [standard deviation (SD)±8.9], with a median of four months (range 1-53 months). The average age at the end of the treatment was 15 months (SD±8.4), with a median of 13 months (range 7-59 months). The mean treatment length was eight months (SD±3.2). Oral propranolol was successful in 95.2% of the patients in reducing the volume, the intensity of color and the elevation of IH. Statistically significant improvement of IH volume was observed in the first two months of therapy (P≤0.001), and between the second month and the end of the treatment (P<0.05). No significant bradycardia or hypotension occurred. Severe hypoglycemia occurred in one patient. Mild adverse effects were observed in seven patients. Our study demonstrates that propranolol administered orally at 2 to 3 mg/kg/day has a rapid therapeutic effect leading to remarkable shortening of the natural course of IH and it is safe in the majority of patients.

Published: June 2016

Meckel’s diverticulum is a common anomaly of the gastrointestinal tract. The most common complications of Meckel’s diverticulum are inflammation, bleeding and obstruction. We present a 12-year-old boy with bowel obstruction due to phytobezoar in a Meckel’s diverticulum. We describe diagnostic difficulties and our surgery approach comparing it to the literature.
Oculo-auriculo-vertebral spectrum with myopathy and velopharyngeal insufficiency. A case report with a non-branchiomeric muscle biopsy
Authors: Murialdo Giovanni , Piazzi Attilia , Badolati Giuseppe , Calcagno Enrico , Berio Agostino
Published: June 2016

In the present paper we report on a case of oculo-auriculo-vertebral spectrum presenting fluorescence in situ hybridization and comparative genomic hybridization tests negative, hypotonia of some branchiomeric muscles (with velo-pharyngeal insufficiency, dysphagia and nasal voice) and non-branchiomeric muscles (with strabismus and limb hypotrophy). On the basis of the left quadriceps muscle biopsy, showing anisometry and prevalence of type 1 fibers, and on literature data, we underline the relevance of TBX1 gene (regulator of neural crest cells and activator of myogenic factors in branchiomeric muscles development) and of PAX3 gene (present in neural crest, inducing migration of these cells and reported in non-branchiomeric muscles). We conclude that the case of OAVS presented a generalized myopathy and we hypothesize that a cluster of genes strictly neural crest cells related, including TBX1 and PAX3, may be responsible of the branchiomeric and non-branchiomeric myopathy; alternatively, a regulatory mechanism abnormally common to OAVS and velo-cardio-facial syndrome could be present.
Laparoscopic treatment of congenital choledochal cyst and hepaticojejunostomy with extracorporeal Roux-en-Y anastomosis: technical aspects and early experience with three cases
Authors: Lima Mario , Gargano Tommaso , Ruggeri Giovanni , Destro Francesca , Maffi Michela
Published: June 2016

Choledochal cyst (CDC) is a congenital dilatation of the extra and/or intrahepatic bile ducts and it is a rare condition in western countries. Classical treatment consists of cyst excision and hepaticojejunostomy. The first case of a laparoscopic CDC excision was described in 1995 and since that time an increasing number of institutions have adopted this technique, with good success. We describe our early experience of 3 cases of CDC treated with laparoscopic approach. We used a 10 mm umbilical port for the camera, and four 3-5 mm operative ports. We performed the laparoscopic removal of the cyst and gallbladder, videoassisted preparation of the Roux-en-Y loop and laparoscopic hepaticjejunostomy. No post-operative complications occurred. Laparoscopic excision of CDCs has been supposed to give better observation, a better cosmetic result, potentially less postoperative pain, and a shorter recovery. The main argument for performing an extracorporeal anastomosis is that it decreases the operative time. We recommend caution to prevent injury to the pancreatic duct and biliary structures during dissection and anastomosis. Lifelong surveillance is mandatory, even after resection of the choledochal cyst.
Preliminary investigations of unconsolidated sediments overlying the Leech River fault zone, southern Vancouver Island, British Columbia
Authors: Bednarski J M
Published: June 2016

The Leech River fault zone lies near the city of Victoria, British Columbia. Although this fault zone has been considered to be inactive for millions of years, two large paleo-earthquakes have been identified on its eastern extension, only 40 km from the city.
Confirmation of an active fault in proximity to an urban centre or a part of critical infrastructure would fundamentally change the analysis of seismic hazard. To determine the occurrence of more recent faulting, younger sediments overlying the faulted bedrock were surveyed by high resolution Lidar
topography, ground penetrating radar, electrical resistivity, and shallow seismic reflection lines. Targeted areas included surface scarps and transects crossing the bedrock structure in search of disturbed sediment that may be attributed to recent faulting. Preliminary results do not find
conclusive evidence of active faulting in the youngest sediment dating from postglacial time, at least in the upper 5 to 10 m; however, the seismic reflection survey found deeper, faulted deposits dating from at least the last glaciation and warrant further investigation.

Renal Artery Stenosis in a Young Female without Fibromuscular Dysplasia with Literature Review
Authors: Peralta Paloma , Cholankeril Matthew , Goldberg Daniel , Koneru Jayanth , Shamoon Fayez
Published: June 2016

Renal artery stenosis (RAS) is rare in young patients without fibromuscular dysplasia (FMD). RAS is primarily classified as having two major etiologies, namely, atherosclerosis and FMD, with 90% and 10%, respectively. We report a case of a female in her mid 20s who developed hypertension due to RAS with no evidence of FMD or underlying renal dysfunction and underwent successful angioplasty and stenting.
Investigating Evolutionary Dynamics of RHA1 Operons
Authors: Chen Yong , Geng Dandan , Ehrhardt Kristina , Zhang Shaoqiang
Published: June 2016

Grouping genes as operons is an important genomic feature of prokaryotic organisms. The comprehensive understanding of the operon organizations would be helpful to decipher transcriptional mechanisms, cellular pathways, and the evolutionary landscape of prokaryotic genomes. Although thousands of prokaryotes have been sequenced, genome-wide investigation of the evolutionary dynamics (division and recombination) of operons among these genomes remains unexplored. Here, we systematically analyzed the operon dynamics of Rhodococcus jostii RHA1 (RHA1), an oleaginous bacterium with high potential applications in biofuel, by comparing 340 prokaryotic genomes that were carefully selected from different genera. Interestingly, 99% of RHA1 operons were observed to exhibit evolutionary events of division and recombination among the 340 compared genomes. An operon that encodes all enzymes related to histidine biosynthesis in RHA1 ( His-operon) was found to be segmented into smaller gene groups (sub-operons) in diverse genomes. These sub-operons were further reorganized with different functional genes as novel operons that are related to different biochemical processes. Comparatively, the operons involved in the functional categories of lipid transport and metabolism are relatively conserved among the 340 compared genomes. At the pathway level, RHA1 operons found to be significantly conserved were involved in ribosome synthesis, oxidative phosphorylation, and fatty acid synthesis. These analyses provide evolutionary insights of operon organization and the dynamic associations of various biochemical pathways in different prokaryotes.
DNA Damage among Wood Workers Assessed with the Comet Assay

Published: June 2016

Exposure to wood dust, a human carcinogen, is common in wood-related industries, and millions of workers are occupationally exposed to wood dust worldwide. The comet assay is a rapid, simple, and sensitive method for determining DNA damage. The objective of this study was to investigate the DNA damage associated with occupational exposure to wood dust using the comet assay (peripheral blood samples) among nonsmoking wood workers ( n = 31, furniture and construction workers) and controls ( n = 19). DNA damage was greater in the group exposed to composite wood products compared to the group exposed to natural woods and controls ( P < 0.001). No difference in DNA damage was observed between workers exposed to natural woods and controls ( P = 0.13). Duration of exposure and current dust concentrations had no effect on DNA damage. In future studies, workers’ exposures should include cumulative dust concentrations and exposures originating from the binders used in composite wood products.
The Noether problem for Hopf algebras
Authors: Kassel Christian , Masuoka Akira
Published: June 2016

In previous work, Eli Aljadeff and the first-named author attached an algebra

\mathcal B_H

of rational fractions to each Hopf algebra

H

. The generalized Noether problem is the following: for which finite-dimensional Hopf algebras

H

is

\mathcal B_H

the localization of a polynomial algebra? A positive answer to this question when

H

is the algebra of functions on a finite group

G

implies a positive answer to the classical Noether problem for

G

. We show that the generalized Noether problem has a positive answer for all finite-dimensional pointed Hopf algebras over a field of characteristic zero (we actually give a precise description of

\mathcal B_H

for such a Hopf algebra).

A theory of polynomial identities for comodule algebras over a Hopf algebra

H

gives rise to a universal comodule algebra whose subalgebra of coinvariants

\mathcal V_H

maps injectively into

\mathcal B_H

. In the second half of this paper, we show that

\mathcal B_H

is a localization of

\mathcal V_H

when

H

is a finite-dimensional pointed Hopf algebra in characteristic zero.We also report on a result by Uma Iyer showing that the same localization result holds when H is the algebra of functions on a finite group.
Hopf-cyclic cohomology of quantum enveloping algebras
Authors: Kaygun Atabey , Sütlü Serkan
Published: June 2016

In this paper we calculate both the periodic and non-periodic Hopf-cyclic cohomology of Drinfeld–Jimbo quantum enveloping algebra

U_q(\mathfrak g)

for an arbitrary semi-simple Lie algebra

\mathfrak g

with coefficients in a modular pair in involution. We obtain this result by showing that the coalgebra Hochschild cohomology of these Hopf algebras are concentrated in a single degree determined by the rank of the Lie algebra

\mathfrak g

Invariant subsets under compact quantum group actions
Authors: Huang Huichi
Published: June 2016

We investigate compact quantum group actions on unital

C^*

-algebras by analyzing invariant subsets and invariant states. In particular, we come up with the concept of compact quantum group orbits and use it to show that countable compact metrizable spaces with infinitely many points are not quantum homogeneous spaces.
Simplicity of twisted $C^*$-algebras of higher-rank graphs and crossed products by quasifree actions
Authors: Kumjian Alex , Pask David , Sims Aidan
Published: June 2016

We characterise simplicity of twisted

C^*

-algebras of row-finite

k

-graphs with no sources. We show that each 2-cocycle on a cofinal

k

-graph determines a canonical second-cohomology class for the periodicity group of the graph. The groupoid of the

k

-graph then acts on the cartesian product of the infinite-path space of the graph with the dual group of the centre of any bicharacter representing this second-cohomology class. The twisted k-graph algebra is simple if and only if this action is minimal. We apply this result to characterise simplicity for many twisted crossed products of

k

-graph algebras by quasifree actions of free abelian groups.
The Standard Model in noncommutative geometry and Morita equivalence
Authors: D'Andrea Francesco , Dąbrowski Ludwik
Published: June 2016

We discuss some properties of the spectral triple

(A_F,H_F,D_F,J_F,\gamma_F)

describing the internal space in the noncommutative geometry approach to the Standard Model, with

A_F=\mathbb C \oplus \\mathbb H \oplus M_3 (\mathbb C)

. We show that, if we want

H_F

to be a Morita equivalence bimodule between

A_F

and the associated Clifford algebra, two terms must be added to the Dirac operator; we then study its relation with the orientability condition for a spectral triple. We also illustrate what changes if one considers a spectral triple with a degenerate representation, based on the complex algebra

B_F =\mathbb C \oplus M_2 (\mathbb C) \oplus M_3(\mathbb C)

.
