Authors: O’Dwyer Sabrina L. , Gupta Manish , Anthony John 
Published: November 2015

AbstractTo describe the etiology and obstetric outcome in women presenting with pulmonary edema during pregnancy and the puerperium. As a secondary objective, we evaluated the utility of echocardiography in the investigation and management of such women.Retrospective case note analysis of 53 cases of pulmonary edema that resulted in severe respiratory distress and admission to intensive care. The study population were women accessing obstetric care at a tertiary referral center in South Africa.Cases were classified as cardiac (6/53; 11%), hypertensive (44/53; 83%), or septic (3/53; 6%), depending on the underlying cause for pulmonary edema. There were significant differences in the mean ejection fraction at echocardiography for cardiac vs. non-cardiac groups (26% vs. 55%, P=0.0001), as well as the presence of valvular stenosis or regurgitation (5/6 vs. 8/30, P=0.016). Women in the non-cardiac group were more likely to present earlier and require earlier delivery than in the cardiac group (median gestation at delivery 35 weeks vs. 38 weeks, P=0.0106) and mothers in the cardiac group were more likely to die (2/6 vs. 1/47, P=0.031). Cesarean delivery was performed in 85% of cases.Hypertensive illness is the most common underlying etiology in the development of pulmonary edema. Transthoracic echocardiography is a non-invasive investigation that can be carried out at the bedside and is a useful diagnostic tool in pulmonary edema occurring in pregnancy and the puerperium. Knowledge of ejection fraction is an important diagnostic tool to differentiate the underlying causes and to guide management.

Published: November 2015

Abstract
In order to reduce cycle times, increase functional integration and automation further, the innovative gap impregnation process and mold technology was developed at the Institute of Plastics Processing at RWTH Aachen University (Germany) in collaboration with industry partners. The novel process enables an automated production of continuous fiber-reinforced sandwich composite structures in integral design with high surface quality in short cycle times, which is demonstrated by manufacturing a carbon fiber-reinforced plastic (CFRP) engine hood. For the first time, the gap impregnation and mold technology makes it possible to manufacture large-scale, three-dimensionally shaped sandwich components in one shot and in short cycle times at similar mechanical properties compared to the reference steel hood. Furthermore, a weight reduction of about 60% to only 5 kg was achieved for the CFRP engine hood. This paper focuses on the systems engineering of the RTM-related gap impregnation process. The focus is on the utilized mold concepts for the pressurized air-assisted ejector pins, vacuum-tight sealing, the motion concept of the mold halves, resin traps, sensors for process control and the specially treated mold surfaces for class A surface components. Additionally, the main procedures, capabilities and characteristics of this innovative process are discussed.
Complexation of amidocarbamoyl phosphine oxides with Ln+3 (Ln = La, Nd, Pm, Sm and Eu) cation series: structural and thermodynamical features
Authors: Hosseinnejad Tayebeh , Kazemi Tayebeh 
Published: November 2015

Abstract
In the present study, we have mainly investigated the nature of interactions in Ln3+ (Ln = La, Nd,
Pm, Sm, Eu) complexes with amidocarbamoyl methyl phosphine oxide (CMPO) and amidocarbamoyl propyl phosphine oxide
(CPPO) ligands based on density functional theory (DFT) approaches. In the first step, thermodynamical properties for complexation of
CMPO and CPPO ligands with Ln3+ cation series have been determined in the gas phase and with the presence of three solvents:
n-hexane, chloroform and toluene, via polarized continuum model (PCM) computations. The trend of metal-ligand interaction strength has
been analyzed and compared with the trend of ionic hardness within the series of lanthanide cations and different size of alkyl chain
of amidocarbamoyl phosphine oxide ligand. The calculated thermochemical results in the gas and solution phases reveals that there is
a consistency between increasing trend in the hardness of Ln3+ cation series and also electron-donating property of alkyl
chain with increasing in thermodynamical stability of [Ln–CMPO]3+ and [Ln–CPPO]3+ complex series. We have also
demonstrated that in the complexation reaction of all complex series, using n-hexane as solvent is more favorable thermodynamically
than chloroform and toluene. It should be stated that this issue has been observed in many experiments. Finally, analysis of calculated
deformation energies and also the variation in bond order of some selected key bonds in CMPO and CPPO ligands and their corresponded
Ln+3 complexes series show a similar trend with increasing in the hardness of Ln3+ cation series and
electron-donating of alkyl chain of amidocarbamoyl phosphine oxide ligand.

Abstract
Chemical studies of superheavy elements require fast and efficient techniques, due to short half-lives and low production rates of the
investigated nuclides. Here, we advocate for using a tubular flow reactor for assessing the thermal stability of the Sg carbonyl
complex – Sg(CO)6. The experimental setup was tested with Mo and W carbonyl complexes, as their properties are established
and supported by theoretical predictions. The suggested approach proved to be effective in discriminating between the thermal
stabilities of Mo(CO)6 and W(CO)6. Therefore, an experimental verification of the predicted Sg–CO bond
dissociation energy seems to be feasible by applying this technique. By investigating the effect of 104,105Mo beta-decay on
the formation of 104,105Tc carbonyl complex, we estimated the lower reaction time limit for the metal carbonyl synthesis in
the gas phase to be more than 100 ms. We examined further the influence of the wall material of the recoil chamber, the
carrier gas composition, the gas flow rate, and the pressure on the production yield of 104Mo(CO)6, so that the future
stability tests with Sg(CO)6 can be optimized accordingly.
Three Korean literati paintings of an orchid in the deconstructive process
Authors: Song Hyosup 
Published: November 2015

AbstractLiterati paintings were drawn by Korean Confucian scholars from the end of the Koryeo period to the end of the Joseon period. As painting these works was considered a method for a scholar’s self-cultivation, literati paintings express plenty of in-depth metaphysical points of significance. Meanwhile, these paintings revealed changes that correspond with changes in cultural circumstances. The present study considers such transformation as a deconstructive process. This research analyzes three Korean orchid paintings to address the following three questions: (1) How are the literati’s thoughts represented in their forms of paintings in the East Asian tradition of poetry–calligraphy–painting in one? (2) How are the interrelations among the pictorial image, verbal message, and empty space revealed in individual literati paintings? (3) How are such interrelations deconstructed amid new cultural circumstances?

Published: November 2015

Objective and designPatients with type 2 diabetes mellitus (T2D) have an increased fracture risk despite a normal or elevated bone mineral density (BMD). The aim of this cross-sectionalin vivostudy was to assess parameters of peripheral bone microarchitecture, estimated bone strength and bone remodeling in T2D patients with and without diabetic microvascular disease (MVD+ and MVD− respectively) and to compare them with healthy controls.MethodsFifty-one T2D patients (MVD+ group:n=25) were recruited from Funen Diabetic Database and matched for age, sex and height with 51 healthy subjects. High-resolution peripheral quantitative tomography (HR-pQCT) was used to assess bone structure at the non-dominant distal radius and tibia. Estimated bone strength was calculated using finite element analysis. Biochemical markers of bone turnover were measured in all participants.ResultsAfter adjusting for BMI, MVD+ patients displayed lower cortical volumetric BMD (P=0.02) and cortical thickness (P=0.02) and higher cortical porosity at the radius (P=0.02) and a trend towards higher cortical porosity at the tibia (P=0.07) compared to controls. HR-pQCT parameters did not differ between MVD− and control subjects. Biochemical markers of bone turnover were significantly lower in MVD+ and MVD− patients compared to controls (allP<0.01). These were no significant correlations between disease duration, glycemic control (average glycated hemoglobin over the previous 3 years) and HR-pQCT parameters.ConclusionCortical bone deficits are not a characteristic of all T2D patients but of a subgroup characterized by the presence of microvascular complications. Whether this influences fracture rates in these patients needs further investigation.
Embodiment of Early Psychosocial Adversity and Allostatic Load Using a Life Course Perspective: A Review
Authors: Barboza Solís Cristina 
Published: November 2015

<p><span>The role of early life experiences on health is a major concern for research and public health interventions. Recent studies show that being exposed to chronic psychosocial stress during sensitive periods of development can have an impact on later health. It appears that children exposed to adverse conditions (economic, material and psychosocial) show a higher risk of adopting deleterious health behaviors (smoking, alcohol), heightened vulnerability to chronic diseases and mortality. Allostatic load (AL) is a measure of overall physiological wear-and-tear that can be the consequence of early life exposures. AL could allow for a better understanding of the potential biological pathways linking adverse exposures and later health. Here we review current evidence to discuss a biological embedding hypothesis, focusing on adverse psychosocial exposures during childhood and its effects on later AL, taking a life course perspective. Via a non-systematic review of recent literature, we examine whether adverse childhood experiences (ACE), causing chronic stress responses, may alter physiological functioning, as measured by AL. A better understanding of the biological mechanisms underlying psychosocial exposures could contribute to the development of more adapted public health interventions, both at a societal and individual level. </span></p>
Possible Link Between Chronic Periodontal Disease and Central Nervous System Pathologies
Authors: Ramírez Chan Karol 
Published: November 2015

<p><span>Systemic infection and/or inflammation has been related with an increased risk of brain abscesses, cerebrovascular disease, cognitive impairment and other pathological states of the brain. Therefore, it is plausible, that a chronic infection and inflammation disease, such as periodontitis, may affect the central nervous system (CNS). Chronic periodontal disease is a condition that causes breakdown of the supporting tissues of the teeth, alveolar bone and soft tissues. Chronic periodontitis is a multifactorial disease caused by dental plaque composed of pathogenic bacteria that triggers the immune response in susceptible hosts. Oral pathogenic bacteria is a source of chronic infection that can induce local and peripheral production of pro-inflammatory cytokines such as IL-1ß, IL-6 and TNF- , inflammatory mediators, as well as bacterial products such as lipopolysaccaride endotoxin. Viruses, such as herpes and Epstein-Barr, can also be found in periodontal pockets. It is well established that oral pathogenic microorganisms may cause systemic infection by transient or persistent bacteremia, disseminating within the body, and infiltrate distal sites and organs. It has been proposed that in vulnerable populations and under certain circumstances, bacterial and viral infections may enter the brain from the bloodstream. Once in the brain, infectious pathogens and inflammatory products may compromise vascular integrity. Thus, the potential role of the pathogenesis of chronic periodontitis in the development and progression of cerebral infection and inflammation can have a link. There is no direct evidence that determines whether oral diseases have a causal association with CNS pathologies, nonetheless there are several reports that have found oral periodontal pathogens lodged in the brain. Both inflammatory states may just share a casual connection with common risk factors and complex multifactorial etiologies. However, the possibility that pathogenic oral microorganisms disseminate to the bloodstream and reach the brain, initiating or exacerbating existing cerebral lesions, cannot be disregarded. In addition, not only periodontal pathogens may be involved in invading the brain, but also, the pro-inflammatory factors induced systemically by periodontitis, may play a role in CNS pathologies. This oral systemic link will be discussed in this paper. </span></p>

Published: November 2015

<p><span>he aim of this In Vivo study was to evaluate the influence of the cavosurface angle (with bevel, and no preparation), of direct composite resin restorations in previous fractured teeth after 4 years of clinical performance. The restorations were performed by a single operator, following a restorative standardized protocol. For the study were selected 24 upper central incisors with fracture or with class IV restorations with an indication of replacement. According to the restorative technique, the teeth were divided into 2 groups: group I (n = 12) Class IV Restorations with a bevel preparation technique; and group II (n = 12) Class IV Restorations performed with no preparation. The restorations were evaluated at 7 days and 4 years, by two examiners, previously calibrated using modified USPHS criteria. After 4 years, two restorations were excluded, representing 22 restorations (11 with bevel preparation, and 11 without). The Fisher test demonstrates no significant differences between groups (p &gt; 0.05). This study presents clinical evidence that the cavosurface angle configuration does not influence the clinical performance of direct composite resin restorations in fractured teeth. Thus, we recommend no preparation of the cavosurface angle to preserve sound dental tissue based on a Minimally Invasive Dentistry approach. </span></p>
Effect of Different Silane-Containing Solutions on Glass-Ceramic/ Cement Bonding Interacting with Dual-Cure Resin Cements

Published: November 2015

<p><span>The aim of this study is to determine the effect of different silane-containing solutions on ceramic-cement bonding and their interaction with different dual-cure resin cements. Forty five glass- ceramic plaques (IPS e.max CAD®) were sandblasted with aluminum oxide for 5s, etched with 10% hydrofluoric acid gel (HF) for 20s and then divided in three groups of 15 each to be treated with different silane-containing solutions: RelyX Ceramic Primer® (AS), Scotchbond Universal® (SU), Clearfil Ceramic Primer® (CP). Then each group was divided in five groups of three plaques to receive the following dual-cure resin cements: Conventional: RelyX Ultimate (RU), RelyX ARC (AR), VarioLink II (VL); and two self-adhesive: RelyX UNICEM 2 (U2), and BiFix (BF). Eight cement cylinders of each cement were distributed on each plaque and polymerized, summarizing 24 cylinders per group. After 24 h storage in relative humidity at 37°C, each cylinder was subjected to a microshear testing. Failure mode was analyzed using scanning electron microscopy (SEM). Data were statistically analyzed with two-way ANOVA (resin cement and silane ) and Tukey test (p≤0.05). Both factors significantly influenced the results and also interaction between them was detected (p=0.0001). μSBS was significantly higher when ceramic was treated with AS for all cements. Most of cements showed no statistically different means when treated with SU and CP, except BF-SU and AR-CP that showed significantly lower means within their treatment groups. Some incomplete polymerization areas were observed in SEM images for those cases. Cohesive failure in resin cement type was predominant with higher results while adhesive with lower results. The sole silane solution improved better bonding than the universal adhesive and the ceramic primer. In general, universal adhesive and ceramic primer produced acceptable mean values and they were statistically comparable. Compatibility between silane solutions and dual-cure resin cements may be material dependent. </span></p>

Published: November 2015

<p>O objetivo principal com este estudo foi realizar uma discussão crítica dos aspectos relativos à aplicação de soluções instantâneas e de forma padronizada na empresa para a solução de conflitos organizacionais. Para tal, a estratégia adotada foi realizar uma interpretação do contexto de relações organizacionais retratadas no filme <em>Up in the air</em>. Para essa interpretação, fundamentalmente, utilizaram-se conceitos da teoria organizacional. Foram escolhidas três principais dimensões de análise: formas convencionais, contraditórias e os diferentes contextos de demissão. Essas formas permitiram a realização da abordagem ao filme, e, sob esse prisma, foi realizada a discussão, construído o mapa conceitual e o modelo conceitual da pesquisa e, posteriormente, discutidos os achados, sempre se procurando identificar a relação entre estes e a teoria organizacional. Utilizou-se neste estudo a revisão sistemática de literatura, escolhida depois de assistido o filme e a partir da reflexão sobre as anotações da síntese. Realizou-se, ainda, a combinação do modelo de análise de filmes proposto por Denzin e Lincoln (2005), que permitiu elaborar uma lista de dimensões ou habilidades possíveis de serem discutidas e posterior associação com a seleção dos artigos em periódicos de fator de impacto relevante, o que culminou na construção do modelo conceitual do trabalho. Além disso, foi utilizada uma metodologia para a apresentação visual dos conceitos-chave por meio de um diagrama hierárquico, o mapa conceitual, que permitiu o melhor entendimento das principais palavras/conceitos-chave. Os principais resultados do estudo estão vinculados à discussão da aplicação dos conceitos extraídos do filme sob a ótica da teoria organizacional e promovem a reflexão entre o observado no filme e as formas de se evitar o caos organizacional.</p><p>Palavras-chave:<strong> </strong>Demissão.

Brucella abortus: patogénesis y regulación génica de la virulencia
Authors: Rivas-Solano Olga 
Published: November 2015

<p class="p1"><em>Brucella abortus </em>es un patógeno intracelular facultativo que pertenece a la subdivisión α2 de la clase Proteobacteria. Causa una brucelosis, una zoonosis ampliamente distribuida a nivel mundial. Los principales síntomas incluyen abortos y esterilidad en ganado, así como fiebre ondulante en humanos. En regiones endémicas como Centroamérica, la brucelosis tiene un alto impacto socioeconómico. En el Instituto Tecnológico de Costa Rica (ITCR) se desarrolló en fecha reciente un proyecto de investigación básica, con el objetivo de estudiar la regulación de algunos genes implicados en la virulencia, estructura e inmunogenicidad de <em>B. abortus</em>. Como parte de ese proyecto se elaboró el presente artículo de revisión de literatura. La virulencia de esta bacteria parece estar determinada por su habilidad para internalizarse, sobrevivir y replicarse dentro de fagocitos profesionales y no profesionales. <em>B. abortus </em>alcanza su nicho replicativo sin activar los mecanismos antimicrobianos de la inmunidad innata del hospedero. Esta bacteria posee sistemas de regulación génica a nivel transcripcional que le permiten una rápida adaptación al ambiente intracelular, entre ellos el sistema de transducción de señales de dos componentes BvrR/BvrS y el regulador de Quorum Sensing llamado Vjbr, así como otros factores de transcripción que, en conjunto, forman una compleja red de regulación génica. </p>
