Sergančiųjų portopulmonine hipertenzija diagnostikos, medikamentinio gydymo ir kepenų transplantacijos ypatumai

Santrauka Šio straipsnio tikslas apžvelgti portopulmoninės hipertenzijos patogenezės, klinikinių išraiškų, diagnostikos ir gydymo aspektus. Tobulėjant bei plečiantis transplantologijos mokslui, portopulmoninė hipertenzija tampa vis aktualesne problema. Maždaug 5-8% kepenų transplantacijai ruošiamų pacientų pasireiškia ši patologinė būklė. Nustatyta, kad portopulmoninė hipertenzija ženkliai didina komplikacijų, susijusių su kepenų transplantacija, riziką bei blogina pacientų prognozę. Tik nuodugnus pacientų ištyrimas ir kompleksinis plaučių kraujotakos hemodinaminių parametrų bei dešiniojo skilvelio funkcijos įvertinimas leidžia parinkti optimalią gydymo taktiką. Šiuo metu portopulmoninės hipertenzijos patogeneziniai mechanizmai nėra iki galo išaiškinti, bet nustatyta, kad jos išsivystymui turi reikšmės plaučių kraujagyslių endotelio pažaida, vazokonstrikcinių mediatorių dominavimas, kraujagyslių remodeliacija ir trombozė. Kol kas portopulmoninės hipertenzijos gydymo standardai yra „pasiskolinti“ iš kitų etiologijų plautinių hipertenzijų gydymo algoritmų, kadangi dar nėra užtektinai perspektyvinių atsitiktinių imčių tyrimų bei visuotinai priimtų rekomendacijų. Svarbiausią grandies vietą šiuolaikiniame plautinės hipertenzijos gydyme sudaro vazodiliatacinės medžiagos. Ankstyvas ir tinkamas medikamentinis gydymas daugeliui pacientų gali palengvinti simptomus, pagerinti bendrą būklę ir netgi įgalinti sėkmingai atlikti kepenų persodinimo operaciją. ĮVADAS Įprastai kraujotaka plaučiuose vyksta žemo spaudimo ir mažo kraujagyslių pasipriešinimo sąlygomis. Plaučių kraujagyslės yra labai elastingos, todėl net ir ženklus cirkuliuojančio kraujo tūrio padidėjimas nežymiai keičia spaudimą plaučių arterijoje. Prie tokių hemodinaminių parametrų yra prisitaikęs ir dešinysis skilvelis (DS). Todėl staiga didėjant spaudimui mažajame kraujo apytakos rate, DS plonasienis miokardas nesugeba adaptuotis prie pokyčių, o tai veda į dešiniųjų širdies kamerų išsiplėtimą ir sąstovį didžiajame kraujo apytakos rate [1]. Dėl kepenų ligų išsivysčius portinei hipertenzijai, daliai pacientų pasireiškia patologinė būklė, vadinama portopulmonine hipertenzija (PPH), kurios metu dėl pokyčių plaučių mikrokraujagyslėse padidėja vidutinis plaučių arterijos spaudimas (VPAS). Tai viena iš plautinių komplikacijų sergantiesiems kepenų ligomis, kuri sukelia daug sunkumų, daro kepenų persodinimo (KTx) operaciją daug pavojingesnę, o kartais priverčia ir atsisakyti šios procedūros. Vis dėlto, didelei daliai sergančiųjų medikamentinis gydymas gali pašalinti ar bent palengvinti minėtą problemą, todėl labai svarbu, kad visi pacientai, ypač ruošiami KTx, būtų nuodugniai ištiriami dėl PPH. Šiame straipsnyje aprašoma PPH patofiziologija, klinikinės išraiškos, diagnostika bei gydymo galimybės.
A POSTMODERN IDEA OF CRITICAL MEDIA LITERACY IN THE AGE OF CONVERGENCE by Madhusmita Boruah

The philosophy of postmodernism is based on the idea of subjective truth which further argues that the meaning-making process is differential and subject to the heterogeneity of culture. In context to postmodernism, the concept of critical media literacy can be understood as a social function of literacy. According to this concept, people do not create meaning in isolation, rather it is a social process in which the existing language system influences in deriving meanings and thereby constructs worldviews. The concept of literacy has been changed from an individual transformation of learning how to read and write to the social transformation of becoming a change agent. Specially in an era when the convergence of media is shaping a new form of meaning-making process in which a text is not in isolation. Convergence of media is leading to need of facilitating multiliteracies in media education for creating a collaborative teaching-learning environment. This study argues that acquiring critical media literacy skills facilitates the students in achieving autonomy in understanding and creating the meaning of experiences accommodating differences in ideas and opinions in the age of convergence.
Interactive visualization of cardiac anatomy and atrial excitation for medical diagnosis and research

Abstract State of the art biomedical engineering allows for acquiring enormous amounts of intracardiac data to aid diagnosis and treatment of cardiac arrhythmias. Modern catheters, which are used to acquire electrical information from within the heart, are capable of recording up to 64 channels simultaneously. The software available for data analysis, however, does not provide adequate performance to neither analyze nor visualize the acquired information in an appropriate manner. We present a software package that fascilitates interdisciplinary collaborations between engineers and physicians to adress open questions about pathophysiological mechanisms using data from everyday electrophysiogical studies. Therefore, a package has been compiled that enables algorithm development using MATLAB and subsequent visualization using the VTK C++ class libraries. The resulting application KaPAVIE, which is presented in this paper, is designed to meet the requirements from the clinical side and has been successfully applied in the clinical environment.
Métodos de análisis genéticos, espaciales y de conectividad en genética del paisaje Genetic, spatial and connectivity methods of analysis in landscape genetics

Resumen. La genetica del paisaje tiene como objetivo evaluar la interaccion de caracteristicas del paisaje (es decir, montanas, corredores) y variables ambientales como temperatura o humedad con procesos microevolutivos como flujo genetico, deriva genica o seleccion. Para ello, la genetica del paisaje se apoya en metodos de analisis de otras disciplinas como genetica de poblaciones, ecologia del paisaje y estadistica espacial, y cuenta ademas con metodos propios. En este trabajo explicamos que es la genetica del paisaje y nos enfocamos en hacer una integracion de las bases teoricas, supuestos, ventajas y limitaciones de los metodos de analisis mas frecuentemente utilizados en genetica del paisaje, apoyada con diversos ejemplos de estudio de caso. Con base en dicha integracion, proponemos que el planteamiento de los analisis en un estudio de genetica del paisaje debe seguir 5 etapas, para cada una de las cuales explicamos sus fundamentos, los metodos mas adecuados y los programas mas utilizados: 1) evaluar los patrones de variacion y estructura genetica, 2) evaluar los patrones de estructura genetica en el espacio, 3) evaluar el flujo genetico (conectividad funcional), 4) evaluar la calidad del paisaje (conectividad estructural) y 5) correlacionar los patrones geneticos con las caracteristicas del paisaje. Finalmente, senalamos las necesidades que consideramos mas urgentes en terminos de desarrollo de metodos de analisis para la genetica del paisaje. Palabras clave: estructura genetica, ecologia molecular, flujo genico, genetica de poblaciones, genetica de la conservacion.
Sialadenitis and Salivary Gland Abscess Refractory to Medical Treatment: An Atypical Presentation of Cat Scratch Disease

Cat scratch disease (CSD) is a benign and self-limiting infectious disease caused by Bartonella henselae. CSD is an important cause of infectious lymphadenopathies and the most common involvement sites are axillary, cervical, preauricular and submandibular lymph node groups. The infection usually occurs in children and young adults who have a history of contact with cats. In this report, we present a previously healthy 42-year-old female presenting with submandibular gland infection and purulent drainage resistant to antibiotics. Infection was succesfully cured after surgical excision of the submandibular gland and the diagnosis of CSD was made on the basis of histolopathological findings of the surgical specimen.

Evidence of polystyrene biodegradation by gut microbiota of Styrofoam-feeding yellow mealworms (larvae of Tenebrio molitor Linnaeus)

[Background] Plastic are synthetic polymers derived from fossil oil and largely resistant to degradation. Plastic litter have adverse effects on the environment and marine biota. Therefore, new solutions for petroleum-based plastic waste degradation are urgently needed. [Objective] Polystyrene (PS) is notoriously persistent plastic that is not degradable at appreciable rates for decades. However, an environment was identified in which PS is susceptible to biodegradation: yellow mealworm, the larvae of Tenebrio molitor Linnaeus, can damage PS packing by chewing and eating styrofoam. So we try to isolate PS-degrading microorganisms from the mealworms’ gut. [Methods] The larvae fed with styrofoam as the sole diet could live as well as those fed with bran diet over several months. Based on morphological, physiological and biochemical properties as well as 16S rRNA gene and ITS gene sequences analysis, the phylogenic tree was constructed to identify the taxonomic status of the strains. [Results] Two bacterial strains capable of degrading styrofoam were isolated from worm fecula egested from styrofoam-feeding larvae, named as Bacillus anthracis PSI-1 and Enterobacter hormaechei PSI-2. A PS-degrading fungal strain was isolated from the gut of mealworms and identified as Aspergillus niger KHJ-1. Over a 14-day incubation period of the fungal train KHJ-1 on PS films, a large number of cavities were obviously observed on PS films surfaces, and the changes were measured about the film of mechanical properties. The results showed that hydrophobicity of the film was decreased dramatically, the elongation at break and the tensile strength became smaller. A suspension culture of KHJ-1 strain was able to degrade 214.8 mg/5 g of PS solid particles, the weight loss ratio of PS was 4.29% over a 60-day incubation period. [Conclusion] The results demonstrated the presence of PS-degrading bacteria and fungus in the guts of mealworms could degrade PS directly and efficiently and provided promising evidence for the biodegradation of PS in the environment.
ENGAGING ADULT LEARNERS: HIGHER EDUCATION AND SELF-CONCEPT DEVELOPMENT

An integral part of learning is the development of academic self-concept. In the field of adult education, there is debate over the extent to which a function of education should be to raise personal as well as academic self-concept. This has resulted in andragogy with different emphases. The Open University in the UK (OU UK) has been successful in enabling adults to succeed in higher education, through engaging supportive teaching and learning techniques in its distance-learning courses. This paper reports on findings from a study which tracked the changes in self-concept of mature women undergraduates who were returning to education after a gap of several years from formal learning. Quantitative and qualitative data were obtained through self-report questionnaires, Q methodology and interviews with women studying various distance learning higher education courses with the OU UK. Key results indicated that it is the participation in as much as the completion of courses that boost women’s personal and academic self-concept. This is relevant to debates regarding the extent to which education and self-concept are entwined and the purpose of adult higher education. It also has implications for the way in which adult education is marketed and delivered.
Investigating Multilingual Abusive Language Detection: A Cautionary Tale

Abusive language detection has received much attention in the last years, and recent approaches perform the task in a number of different languages. We investigate which factors have an effect on multilingual settings, focusing on the compatibility of data and annotations. In the current paper, we focus on English and German. Our findings show large differences in performance between the two languages. We find that the best performance is achieved by different classification algorithms. Sampling to address class imbalance issues is detrimental for German and beneficial for English. The only similarity that we find is that neither data set shows clear topics when we compare the results of topic modeling to the gold standard. Based on our findings, we can conclude that a multilingual optimization of classifiers is not possible even in settings where comparable data sets are used.
The CitySPIN Platform: A CPSS Environment for City-Wide Infrastructures

Cyber-physical Social System (CPSS) are complex systems that span the boundaries of the cyber, physical and social spheres. They play an important role in a variety of domains ranging from industry to smart city applications. As such, these systems necessarily need to take into account, combine and make sense of heterogeneous data sources from legacy systems, from the physical layer and also the social groups that are part of/use the system. The collection, cleansing and integration of these data sources represents a major effort not only during the operation of the system, but also during its engineering and design. Indeed, while ongoing efforts are concerned primarily with the operation of such systems, limited focus has been put on supporting the engineering phase of CPSS. To address this shortcoming, within the CitySPIN project we aim to create a platform that supports stakeholders involved in the design of these systems especially in terms of support for data management. To that end, we develop methods and techniques based on Semantic Web and Linked Data technologies for the acquisition and integration of heterogeneous data from disparate structured, semi-structured and unstructured sources, including open data and social data. In this paper we present the overall system architecturewith a core focus on data acquisition and integration.We demon-strate our approach through a prototypical implementation of an adaptive planning use case for public transportation scheduling.
Proof of Credibility: A Blockchain Approach for Detecting and Blocking Fake News in Social Networks

Rumors and misleading information detection and prevention still represent a big challenge against social network developers and researchers. Since newsworthy information propagation is a traditional behavior of most of the users in social media, then verifying information credibility and reliability is indeed a vital security requirement for social network platforms. Due to its immutability, security, tamper-proof and P2P design, Blockchain as a powerful technology can provide a magical solution to overcome this challenge. This Paper introduces a novel blockchain approach called Proof of Credibility (PoC) for detecting fake news and blocking its propagation in social networks. The functionality of the PoC protocol has been simulated on two datasets of newsworthy tweets collected from different news sources on Twitter. The results clarified a satisfying performance and efficiency of the proposed approach in detecting rumors and blocking its propagation.
Financial inclusion and patience: Longitudinal evidence from Indonesia

Financial development plays a key role in economic growth, but there is little evidence on how greater access to financial services affects households’ patience when making intertemporal choices. Theory suggests that such choices are guided by interest rates when individuals freely access banking services and reflect underlying time preference parameters when individuals are credit constrained. This may lead to a reduction in the patience of individuals when the financial system expands, especially when saving in banks increases. This study is the first to empirically examine the effect of greater financial inclusion on patience using longitudinal data. Analyzing two waves of the Indonesian Family Life Survey that spans a period of rapid expansion of bank branches to rural villages, I find that a commercial bank branch in the village reduces measured patience, and the result remains robust using matching estimators. I also find evidence that financial access affects patience mainly by increasing access to deposit services rather than loans.
A Comparative Study on the Technologies of Project Management and their Compatibility with Software Development Methodologies (Case Study: Software Companies in Iran)

In developing countries, one of the problems in the successful implementation of projects is that project management techniques are not applied. This problem results in a huge loss of financial and human resources . Nowadays project management has become a knowledge for which some standards have been defined to guarantee the existence of desired executive methods and identify the relevant elements. In this paper, the standards of project management were explained comparatively first. Then various software development methodologies were studied. Each methodology had a dedicated process and attributes. After that, the consistence of this project with software development standards were investigated . In this study, a questionnaire was used to investigate the compatibility of project management methods with software development methodologies. The information of statistical samples were provided by different software roles in various software companies with statistical methods. Then the information was analyzed in SPSS. After that, it was clarified that knowing PMBOK had a positive impact on projects so that it would become more compatible with RUP.
RANDOM GRAPHS ARISING FROM L-FUNCTIONS AND MODULAR FORMS: TOPOLOGICAL PROPERTIES AND PHASE TRANSITIONS

A construction is proposed, relating L-functions and modular forms with the theory of random graphs. A new class of graphs with a power-law type degree distribution, called zeta graphs is introduced: each model is realized by assigning a specific Dirichlet series, that governs the topology of the associated network. A large family of scale-free networks is obtained by introducing a product in the space of random graphs, which allows to generate new graphs from old ones. A particularly relevant class of zeta graphs, called modular graphs, is attached to modular forms of integer weight, and specifically to Eisenstein series. In this construction, Hecke-type operators are defined, mapping modular graphs into modular graphs. A crucial feature of the models presented is the existence of a phase transition in terms of the creation of a giant cluster. A theorem is proved giving the analytic condition for the existence of a giant component. The critical point at which the phase transition can occur is defined by a functional equation for the L-function governing the model considered. This transition can be interpreted in the context of percolation theory as a threshold for describing percolation phenomena. MSC Classification: 11M36, 11F11, 60B99
Offence in Dialogues: A Corpus-Based Study

In recent years an increasing number of analyses of offensive language has been published, however, dealing mainly with the automatic detection and classification of isolated instances. In this paper we aim to understand the impact of offensive messages in online conversations diachronically, and in particular the change in offensiveness of dialogue turns. In turn, we aim to measure the progression of offence level as well as its direction - For example, whether a conversation is escalating or declining in offence. We present our method of extracting linear dialogues from tree-structured conversations in social media data and make our code publicly available. Furthermore, we discuss methods to analyse this dataset through changes in discourse offensiveness. Our paper includes two main contributions; first, using a neural network to measure the level of offensiveness in conversations; and second, the analysis of conversations around offensive comments using decoupling functions.
The Estimation and Decomposition of Tourism Productivity: Into a More Robust Estimation using Bayesian Techniques Introduction

Despite being a high priority on the World Tourism Organization (UNWTO) research agenda, the productivity analysis of the tourism industry has not received much attention in the tourism literature. There is a continuous effort at most tourism destinations to strengthen the productivity of their tourism industry (Cvelbar et al. 2015). As stated by Assaf and Dwyer (2013), with the tourism industry often perceived as a low productivity industry, productivity analysis is “crucial to evaluating tourism sustainability and reshaping tourism activities. There is a direct link between productivity and profitability, as when productivity increases, the tourism industry’s competitiveness in labour, capital and real estate markets also increase”.
Insulin-dependent Diabetics

Background-Direct association of trace and macro-elements in relation to human disease has been observed in many research studies. In many cases, an alteration in the metabolism of these minerals has been demonstrated. Methods-In this investigation, the serum and hair levels of the trace elements zinc (Zn), copper (Cu), chromium (Cr), manganese (Mn) and the macro-element magnesium (Mg) were determined in 40 subjects (20 insulin-dependent diabetics and 20 controls). Samples were analyzed using atomic absorption spectrophotometric methods. Results-Serum levels for Zn were lower in the patient groups in comparison to the controls (p<0.01), however, Zn levels in hair follicles were not found to be statistically different. Serum Cu levels were significantly higher in diabetic subjects (p<0.008) where as hair levels were unaltered. Comparison of levels of Cr in hair samples revealed a significant difference between patients and controls (p=0.001). Serum Mn evaluation revealed no significant difference between mean levels of controls and patients (p<0.96), but hair follicle analysis revealed a significant difference between the two groups. For Mg, statistical analysis indicated a significant difference in the two groups of serum levels (p<0.0007), with hair samples showing no significant difference (p<0.01). These results are consistent with results obtained by some other researchers.
Robust Optimized Discrete Wavelet Transform-Singular Value Decomposition Based Video Watermarking

Received: 2 September 2019 Accepted: 13 November 2019 The effortless editing, interchanging and replication of multimedia data on the internet is growing exponentially and has created copyright protection uncertainties for content providers. Thus, in order to discourage illegal duplication and to attain the required level of protection to digital data, digital watermarking is found to be a feasible solution. Thus, this paper proposes a video watermarking technique by exploring Discrete Wavelet Transform (DWT) and Singular Value Decomposition (SVD) transform in addition to Artificial Bee colony (ABC) Optimization algorithm. In this paper, DWT is applied on every luminance frame which is divided into 8x8 blocks of the video ‘V’ thus producing distinct frequency sub-bands. Out of them, LL band is selected for watermark insertion. Later SVD transform is implemented on the selected dwt blocks of LL bands of all frames. The starting indices of best blocks are obtained adaptively rather than manually through ABC algorithm. At the receiving part, retrieval of watermark contents is achieved by a similar evaluation scheme practiced during the embedding procedure. The proposed optimized DWT-SVD based video watermarking method has been evaluated in the presence of video processing attacks and simulation results proved that due to cascading of two powerful mathematical transforms DWT and SVD in addition to ABC algorithm the proposed video watermarking method endures all attacks and aptly extracts the concealed watermark without significant degradation in the video quality of the watermarked video. Thus when the Peak Signal to Noise Ratio (PSNR) and Normalized Correlation (NC) performance of the proposed algorithm is correlated with other related techniques it is found that the PSNR of the proposed method is above 53 dB for all set of videos and Robustness of the scheme is superior than the existing schemes for similar set of videos in terms of NC.
