<p>A female patient, 60 years of age, was presented to our hospital with chest pain and monomorphic ventricular tachycardia (VT). She was transferred to the Coronary Care Unit and amiodarone perfusion restored basal rhythm in atrial fibrillation. She has not sign of heart failure. A transtoracic echocardiogram (TTE) was performed and an one mitral mass was found at atrioventricular junction with displacement of the posterior mitral leaflet A transesophageal echocardiogram (TEE) demonstrated a mass at atrioventricular junction level with severe mitral regurgitation. Cardiac Magnetic Resonance (CMR) confirmed the mass and anterolateral papillary muscle was thickening and hypertrophied with hyperenhancement consistent with fibrosis. Moreover, T2-weighted imaging demonstrated hyperintense mass with respect to the surrounding myocardium in relation of inflammatory mass. She had saddle nose by destruction of the septum, bilateral hearing loss, sinusitis and scleritis and renal involvement as well. This patient was diagnosed of Wegener's Granulomatosis (WG) and she was treated with methylprednisolone during 3 days, continued with prednisolone and cyclophosphamide. An 8 days later echocardiogram did not find the mass. However, the patient developed symptomatology of heart failure and in the context of severe mitral regurgitation, mitral valve replacement was decided in multi-disciplinary Cardiology-Cardiothoracic meeting.</p>
Além dos @teísmos na contemporaneidade

Published: November 2016

Resumo: este artigo faz um percorrido das formulações teóricas e práticas, na contemporaneidade, dos ateísmos em contraposição ao teísmo medieval. Procura-se refletir sobre o caldeirão cultural ateu florescido na modernidade, de alguma forma confrontado no projeto filosófico do pós-modernismo, sobrevivendo na pós-modernidade e subsistindo na transmodernidade. O cenário da contemporaneidade é de @teísmos, isto é, de ateísmos e teísmos que se confrontam na arena digital de forma light, ao menos no âmbito das formulações teóricas, e se apresenta como uma provocação para a reflexão sobre a importância positiva das correntes ateias como uma instância crítica sobre as religiões e seus valores, bem como seus possíveis desvios, na busca de um diálogo respeitoso.

Reflexões sobre a Filosofia da História de Immanuel Kant
Authors: Sousa Ágabo Borges 
Published: November 2016

Resumo: talvez não sejam muito conhecidos os textos de Kant: “Ideias para uma História Universal do Ponto de Vista Cosmopolita” e “Provável Início da História Humana”, quando ele discute alguns aspectos para uma filosofia da história. Estes textos, especialmente, o “Provável Início da História Humana” abrem-nos possibilidade de uma discussão em torno dos conceitos de história provável e história criada. Considerando que “um relato do início do desenvolvimento da liberdade desde sua predisposição original na natureza humana é, portanto, algo inteiramente diferente do que um relato histórico da evolução dessa liberdade, um relato que só pode ser baseado em informações históricas” (KANT, 2012, p. 46), podemos dizer com Kant, que não há como fazer uma Historiografia documental do início da história humana. Para ele, isso seria, fundamentalmente, um exercício que se consente à imaginação. Este começo não precisa ser fabricado, “mas pode ser derivado da experiência se se assume que essa experiência não era melhor ou pior em sua origem do que é presentemente (KANT, 2012, p. 46). Podemos, portanto, tomar um fio condutor conectado à experiência da razão e seguir um roteiro. Kant escolhe utilizar “um documento sagrado” e desenvolve sua reflexão a partir de Gênesis, um texto bíblico. Gostaria de refletir até onde este caminhar de Kant nos ajudaria a pensar filosoficamente a parte mais antiga da história humana e como textos mitológicos nos servem de documentos filosóficos e históricos para uma reflexão do ser humano em sua gênesis.

StructAnalyzer - a tool for sequence vs. structure similarity analysis
Authors: Wiedemann Jakub , Miłostan Maciej 
Published: November 2016

In the world of RNAs and proteins similarities on the level of primary structures of two comparable molecules usually correspond to structural similarities on the tertiary level. In other words, measures of sequence and structure similarities are in general correlated – high value of sequence similarity impose high value of structural similarity. However important exceptions that stay in contrary with the general rule can be identified. It is possible to find similar structures with very different sequences and also similar sequences with very different structures. In this paper we focus attention on the latter case and propose a tool, called StructAnalyzer, supporting analysis of relations between sequence and structure similarities. Recognition of diversity of tertiary structures of molecules with very similar primary structures may be the key for better understanding of mechanisms influencing folding of RNA or proteins and as result their function. StructAnalyzer allows exploration and visualization of structural diversity in relation to sequence similarity. We show how the tool can be used to screen RNA structures in PDB for sequences with structural variants.
Limited Evidence for a Guided Bone Regeneration Procedure Commonly Performed in Contemporary Clinical Practice

Published: November 2016

Focused Clinical QuestionWhat is the efficacy of a guided bone regeneration procedure, consisting of the combination of allograft particles and an absorbable collagen membrane, in horizontally augmenting alveolar bone in a healthy white patient, compared with other horizontal ridge augmentation techniques?Clinical ScenarioA 20‐year‐old white female presented to the University of Iowa College of Dentistry Faculty Practice (Iowa City, Iowa) in April 2014 with a chief complaint of “I lost one of my upper front teeth and I would like to replace it.” Her medical history was non‐contributory, and she never smoked. Tooth #11 was extracted in an oral surgery practice, alongside her third molars, ≈2 years before the consultation for tooth replacement. The reason for extraction was severe tooth malposition and ankylosis. Extensive bone removal was required at the time of extraction. Intraoral examination revealed a marked horizontal ridge deficiency, which was confirmed radiographically on cone‐beam computed tomography scan analysis, necessitating bone augmentation before implant placement in an ideal restorative position.
Efficient Removal of Enhanced-Oil-Recovery Polymer From Produced Water With Magnetic Nanoparticles and Regeneration/Reuse of Spent Particles
Authors: Ko Saebom , Lee Hyunjae , Huh Chun 
Published: November 2016

Summary
Polymer flooding is a proven technology to improve sweep efficiency, while being one of the most economical enhanced-oil-recovery (EOR) processes. Partially hydrolyzed polyacrylamide (HPAM) has been widely used for polymer flooding. As the HPAM usage for EOR increases, the challenge of produced-water management is also raised because residual HPAM in produced water could increase oil content and unwanted viscosity in discharging or reinjecting the water. As the environmental standards and regulations get more stringent, it is difficult for the conventional methods to meet the requirement for discharge. Use of magnetic nanoparticles (MNPs) to remove contaminants from produced water is a promising way to treat produced water in an environmentally friendly way with minimal use of chemicals. The main attraction for MNPs is their quick response to move in a desired direction with application of an external magnetic field. Another attraction of MNPs is versatile and efficient surface modification through suitable polymer coating, depending on the characteristics of target contaminants. In this study, we investigate the feasibility of polymer removal with surface-modified MNPs and regeneration of spent MNPs for multiple reuse.
MNPs, in-house synthesized with prescribed surface coating, were superparamagnetic with an average individual particle size of ≈10 nm. The removal efficiency of HPAM from water with the MNPs depended on the type and concentration of brines, concentration of amine-functionalized MNPs, surface coating of MNPs, molecular weight of polymer, and how many times the MNPs were regenerated and reused. Virtually 100% removal of HPAM from water was feasible, depending on the reaction conditions. The regeneration of spent MNPs, with pH adjustment to recover the reactive sites, maintained more than 90% removal efficiency for three-time repetitive usages.
The electrostatic attraction between negatively charged HPAM polymer and positively charged MNPs controls the attachment of MNPs to HPAM molecular chains; the subsequent aggregation of the now neutralized MNP-attached HPAM plays a critical role for accelerated and efficient magnetic separation.

Summary
Steamflooding is a widely used technique for heavy-oil recovery. Scale control during steamflooding, however, can be challenging because the high temperature of the steamflood can decompose thermally unstable inhibitors and/or lead to the precipitation of metal-inhibitor pseudoscale. In this paper, we present the analysis of the scaling risk and scale inhibition for a pilot steamflood project in a Middle Eastern oil field. The formation of this field is a dolomite formation interbedded with anhydrite (CaSO4) streaks. Anhydrite has been observed to be the predominant scale form. Anhydrite scale was presumably formed by the increased production-system temperature resulting from steamflooding and/or the mixing of steam condensate with connate water at equilibrium with calcium sulfate minerals at lower temperature and higher solubility. Anhydrite is inherently difficult to control because of its high solubility and the high-temperature (HT) conditions under which it forms. Compared with barite and calcite, only limited knowledge has been acquired for anhydrite control. To predict the scaling tendency and inhibitor need in different wells of this field with different supersaturation levels and temperatures, a scaling-risk model has been developed. To build such a model, detailed and revised laboratory procedures have been developed to study nucleation and precipitation kinetics of anhydrite at 125–175°C, different supersaturation, different water composition, and long reaction time. Predictions of this scaling-risk model suggest a saturation index (SI) of 0.8 as a critical SI for anhydrite control at &gt;125°C. For example, when the SI is above 0.8, anhydrite will be difficult to control in the presence of threshold inhibitor. Model predictions were benchmarked with the water-chemistry data from a total of more than 20 wells from this field, and were found to be consistent with field observations of scale occurrence in different wells. With the recommended inhibitor concentrations, anhydrite scale has been controlled in this field, which provides validation that the proposed scaling-risk model is a powerful tool to optimize the scale-treatment plan for anhydrite.

Published: November 2016

The probability of dry eye syndrome (DES) in the patients using the Silicone-Hydrogel Contact Lenses is examined in many researches. Therefore, adhering to clinical recommendations is an important factor for DES prevention. The urgent issue is also a comprehensive assessment of functional parameters as pathogenetic base of DES.The objective of the research was tostudy DES development depending on compliance of silicone hydrogel contact lenses users.Matherials and methods. 97 patients (194 eyes) were included into the research. They formed 2 groups: group I with incomplete compliance (36 persons) and group II with complete compliance (61 persons). All the patients underwent the Norn’s test, Schirmer’s test, Jones test, tear film stability was defined. The probability of the dry eye syndrome development due to the subjective signs was also analysed.Results. The reliable decrease in the total (р<0.05) and basale lacrimation (р<0.05) indexes, the increase in osmolarity (р<0.05) and decrease in tear film stability (р<0.05) were detected in the patients who did not follow the clinical guidance during the Silicone-Hydrogel Contact Lenses wearing. In the same group the higher risk of dry eye syndrome development was verified (р<0.05).Conclusion. Compliance disorder in the patients using Silicone-Hydrogel Contact Lenses was found to induce the reliable decrease in total and basale lacrimation, increase in osmolarity and tear stability disorder. All of this factors increase the risk of dry eye syndrome.

A distinctive feature of patients with ankylosing spondylitis is the formation of hip ankylosis in an extremely unfavorable functional position combined with upset of sagittal balance of the body along with a thoracolumbar kyphosis. Treatment of these patients poses considerable technical difficulties and is often associated with complications. The authors report a clinical case of a female 40 years old patient with confirmed rhizomelic spondylitis. The patient mainly complained of fixed malposition of the right lower extremity (hip ankylosis in extreme 1450 flexion and 1500 abduction) combined with a severe fixed spine deformity (thoracic kyphosis 920, lumbar lordosis 170). Considering significant sagittal balance disorder it was decided to go for a two-stage procedure. Total hip arthroplasty of the right joint was performed at the first stage. At the second stage the authors corrected thoracolumbar spinal deformity by Th12 (type PSO 4) and L2 (type PSO 3) wedge resections and converging resected vertebral bodies by a multilevel fixation system with transpedicular support elements. The interval between the stages was 11 months. Two-stage treatment of this patient al-lowed to avoid adverse postoperative complications and to achieve a significant functional improvement in one year after treatment started. The sum of points before and after the treat-ment amounted respectively to 46 and 79 on Harris Hip Score, 17 and 38 points on Oxford Hip Score (OHS). To summarize, comprehensive treatment with planning of all subsequent steps prior to hip replacement is the method of choice for avoidance of postoperative complications in patients with ankylosing spondylitis accompanied by a significant upset of sagittal balance.

Published: November 2016

Purpose of the study: to evaluate osteogenic rate of various characteristics of mechanical loading based on the authors’ data as well as literature analysis.Literature analysis proved that clinical outcome of physical training can be achieved not only by increasing the mechanical load but also by altering number of load iterations, rate of load acceleration, frequency of cyclic load, rest interval, distribution of load across the skeleton. Presented data provides a reasonable basis to apply alterations of all above-mentioned load characteristics to obtain clinical effect and customize every single baseline exercise plan to gain a maximum treatment and preventive effect in individuals with high risk of osteoporotic fractures.
