Voices of Quiet Students: Introverted Nursing Students’ Perceptions of Educational Experiences and Leadership Preparation
Authors: Colley Sharon L
Published: January 2019

The nursing profession needs leaders from across the temperament continuum. Educational environments are conducive to extroverts’ learning but can have detrimental outcomes for introverted students. Introverted nurses avoid leadership positions because they have been taught extroversion traits are needed. This study explores perceptions of seven RN-BSN students who work as nurses and self-identify as introverts. Interviews with participants were conducted to ascertain perceptions of their educational experiences including preparation for leadership positions. Four themes emerged as: (1) stop making me sick, and I will appreciate learning, (2) respect my silence, and I will eventually speak, (3) recognize my strengths, and I will grow in confidence as a leader, and (4) adapt the environment, and I will learn more. Implications for nurse educators include being mindful to avoid bias and reduce stigma, considering changes to teaching approaches to create equitable learning spaces, and respecting silence in the classroom.
Knockdown of Fidgetin Improves Regeneration of Injured Axons by a Microtubule-Based Mechanism
Authors: Matamoros Andrew J. , Tom Veronica J. , Wu Di , Rao Yash , Sharp David J. , Baas Peter W.
Published: January 2019

Fidgetin is a microtubule-severing protein that pares back the labile domains of microtubules in the axon. Experimental depletion of fidgetin results in elongation of the labile domains of microtubules and faster axonal growth. To test whetherfidgetinknockdown assists axonal regeneration, we plated dissociated adult rat DRGs transduced using AAV5-shRNA-fidgetinon a laminin substrate with spots of aggrecan, a growth-inhibitory chondroitin sulfate proteoglycan. This cell culture assay mimics the glial scar formed after CNS injury. Aggrecan is more concentrated at the edge of the spot, such that axons growing from within the spot toward the edge encounter a concentration gradient that causes growth cones to become dystrophic and axons to retract or curve back on themselves.Fidgetinknockdown resulted in faster-growing axons on both laminin and aggrecan and enhanced crossing of axons from laminin onto aggrecan. Strikingly, axons from within the spot grew more avidly against the inhibitory aggrecan concentration gradient to cross onto laminin, without retracting or curving back. We also tested whether depleting fidgetin improves axonal regenerationin vivoafter a dorsal root crush in adult female rats. Whereas control DRG neurons failed to extend axons across the dorsal root entry zone after injury, DRG neurons in whichfidgetinwas knocked down displayed enhanced regeneration of axons across the dorsal root entry zone into the spinal cord. Collectively, these results establish fidgetin as a novel therapeutic target to augment nerve regeneration and provide a workflow template by which microtubule-related targets can be compared in the future.

SIGNIFICANCE STATEMENTHere we establish a workflow template from cell culture to animals in which microtubule-based treatments can be tested and compared with one another for their effectiveness in augmenting regeneration of injured axons relevant to spinal cord injury. The present work uses a viral transduction approach to knock downfidgetinfrom rat neurons, which coaxes nerve regeneration by elevating microtubule mass in their axons. Unlike previous strategies using microtubule-stabilizing drugs,fidgetinknockdown adds microtubule mass that is labile (rather than stable), thereby better recapitulating the growth status of a developing axon.

Published: January 2019

Alkali bees (Nomia melanderi) are solitary relatives of the halictine bees, which have become an important model for the evolution of social behavior, but for which few solitary comparisons exist. These ground-nesting bees defend their developing offspring against pathogens and predators, and thus exhibit some of the key traits that preceded insect sociality. Alkali bees are also efficient native pollinators of alfalfa seed, which is a crop of major economic value in the United States. We sequenced, assembled, and annotated a high-quality draft genome of 299.6 Mbp for this species. Repetitive content makes up more than one-third of this genome, and previously uncharacterized transposable elements are the most abundant type of repetitive DNA. We predicted 10,847 protein coding genes, and identify 479 of these undergoing positive directional selection with the use of population genetic analysis based on low-coverage whole genome sequencing of 19 individuals. We found evidence of recent population bottlenecks, but no significant evidence of population structure. We also identify 45 genes enriched for protein translation and folding, transcriptional regulation, and triglyceride metabolism evolving slower in alkali bees compared to other halictid bees. These resources will be useful for future studies of bee comparative genomics and pollinator health research.
Artifacts, Visual Modeling and Constructionism: To Look More Closely, to Watch What Happens
Authors: Clayson James E.
Published: January 2019

[full article, abstract in English; abstract in Lithuanian]

Constructionists operationalize a powerful notion they share with constructivists: individual learning is facilitated by building models of specific ideas, concepts, methods, objects, environments, feelings, dreams, memories and sounds using the learner’s current stock of knowledge. Constructionists do this by building models or artifacts that can be externally manipulated, interrogated by their builder, and verbally shared with others. Constructionists believe that new knowledge is created during these discussions. Constructionism is rich with heuristic methods for both finding and constructing artifacts and for discussing these artifacts privately and publicly. Constructionists argue that both constructing and discussing are necessary for deep sense-making.

This paper describes one specific constructionist learning method: visual modeling. It illustrates one educator’s approach, developed in the classroom over a 40-year period. It references the relevant literature; describes its pedagogic approach, materials and outcomes; and it offers a step-by-step example of one student’s thinking process. Finally, it presents – in appropriate narrative form – 15 arguments why the visual component extends the constructionist project and should be integrated into more educational programs.

Contraceptive Initiation Among Women in the United States: Timing, Methods Used, and Pregnancy Outcomes
Authors: Murray Horwitz Mara E. , Ross-Degnan Dennis , Pace Lydia E.
Published: January 2019

BACKGROUND:

Timely contraceptive initiation is increasingly common, yet population trends by method and among subgroups with increased risk of unintended pregnancy are not well described. The impact of timing and type of contraceptive initiation on risk of unwanted pregnancy is unknown.

METHODS:

We used nationally representative cross-sectional data from 4 cycles of the National Survey of Family Growth, 2002–2015. We calculated outcomes from self-reported dates of sexual debut, contraceptive initiation, and unwanted pregnancy. We compared trends in timely contraceptive initiation (within 1 month of sexual debut) by method and by race and/or ethnicity and income. Using multivariable regression, we identified predictors of delayed contraceptive initiation. We compared the risk of unwanted pregnancy for delayed versus timely contraceptive initiation.

RESULTS:

We analyzed responses from 26 359 women with sexual debuts in 1970–2014. One in 5 overall and 1 in 4 African American, Hispanic, or low-income respondents reported delayed contraceptive initiation, which was associated with unwanted pregnancy within 3 months of sexual debut (adjusted risk ratio 3.7 versus timely contraceptive initiation; 99.9% confidence interval: 2.3–5.9; P < .001). Timely contraceptive initiation with less effective versus effective methods was not associated with unwanted pregnancy within 3 months.

CONCLUSIONS:

Delayed contraceptive initiation is more common among African American, Hispanic, and low-income women and is strongly associated with short-term risk of unwanted pregnancy. Pediatricians play a key role in making timely contraception available to adolescents at or before sexual debut. More research is needed to understand the importance of early contraceptive methods on pregnancy risk.

Una civilización del odio
Authors: Sauret Marie-Jean
Published: January 2019

El odio caracterizaría nuestra época, aún si este es de “un acceso menos fácil a nuestro consentimiento”. Para esclarecer la paradoja —odio, civilización, consentimiento— estos conceptos serán interrogados cruzando la lógica del discurso analítico con la lógica neoliberal que preside “nuestro” destino. “El odio es una pasión del ser” al que este apunta, ¿pero por qué el ser desencadena el odio? Este examen nos lleva de lo real del sujeto hacia el odio a Dios: lo trascendente religioso responde a lo impensable del sujeto. Por añadidura, si el discurso capitalista rechaza las cosas del amor, ¿acaso no forcluye el odio de la misma manera? El psicoanálisis permite pensar una sociedad de “la no relación”; ciertamente restaura la posibilidad de tomar la medida de su propio odio, pero también de darle lugar al amor.
El odio, una pasión diferente de las demás
Authors: Izcovich Luis
Published: January 2019

A partir de las tres pasiones del ser indicadas por Lacan —la ignorancia, el amor y el odio— se tratará de situar la relación entre la pasión y el saber. En ese recorrido se subrayará la forma que puede tomar el odio en la transferencia y su devenir en el análisis y, para ello, se impondrán una serie de distinciones sobre las manifestaciones clínicas del odio. Estas elaboraciones apuntan a subrayar los efectos de un análisis sobre el odio y la imposibilidad de que la experiencia analítica encuentre, como momento conclusivo, la emergencia de un odio que fuese un odio de separación. Si el odio conduce a la separación con el analista, esto no hace que el Otro quede destituido, sino todo lo contrario: el odio está al servicio de hacer existir al Otro.
Un mundo congelado. Acerca de la desmentida de la ambivalencia
Authors: Drivet Leandro
Published: January 2019

Este trabajo reflexiona sobre la tendencia de la moral occidental a negar la ambivalencia de la pulsión, desde un punto de vista en el que el psicoanálisis dialoga con la literatura, la filosofía, la etnología y la antropología. Esta perspectiva cuestiona tanto la abstracción demonizante de la agresividad, el odio y la muerte, como la idealización desustancializada del sexo, el amor y la vida. Así, habilita una valoración de la ambivalencia que nos obliga a pensarnos como mortales y como mortíferos y, además, nos enfrenta a algunos viejos aspectos actualizados del sentimiento de culpabilidad vinculados con la oralidad. La desmentida de la ambivalencia es solo un aspecto de la pretendida renuncia teológica o “racional” de las pasiones y la cultura.

Volviendo a poner en juego el mito del asesinato del padre en la era contemporánea, este artículo hace un intento por evaluar, tanto en las modalidades de organización subjetiva como en la conducción de la cura, los destinos diferenciados de la represión y de la desmentida de la figura original del padre, porque es a él a quien se dirige estructuralmente el odio.
Sobre los bebés, el odio y la invocación
Authors: Lares Miguel Jorge
Published: January 2019

Todo estudio que concierna a la pasión del odio (pasión que como tal es ubicable ya en la problemática del espejo) deberá tener en cuenta que la audibilidad e inaudibilidad, la aceptación y el rechazo de la invocación originaria, se dan en un tiempo que no es mítico ni histórico dentro del cual lo inexistente es llamado a advenir en relación con una voz encarnada. Freud descubrió que el odio precede al amor que viene a recubrirlo y, por lo tanto, el odio es primero pero no primario. El sujeto se constituye en una relación con el Otro que es de “exclusión interna”, en un rechazo primordial que es también aceptación. Ese momento lógico, de coalescencia y soldadura, de corte y anudamiento, propicia ese montaje escénico en que el hombre odia al otro que hay en él, el más cercano y el más extraño.
El cuerpo y sus vicisitudes en la anorexia mental: entre el odio y el superyó
Authors: Abínzano Rodrigo , Fernández Lorena Patricia
Published: January 2019

En este trabajo indagaremos los lugares del odio y el superyó en la constitución corporal de la anorexia. Encontramos en estos sujetos perturbaciones de la percepción corporal que nos llevan a preguntarnos por la imagen narcisista. Además, advertimos que en la conformación del cuerpo del sujeto con anorexia prevalece el odio como pasión, revelado a través del superyó. Para ello delimitaremos la incidencia del Ideal del yo y del superyó en la constitución de la imagen; realizaremos un abordaje de la relación del superyó con el odio, el amor y la ignorancia; indagaremos la articulación entre el cuerpo en la anorexia y el odio como ideal; de este recorrido derivaremos algunas conclusiones.
Apuntes sobre el discurso del odio en la sociedad contemporánea
Authors: Bonnett Piedad
Published: January 2019

El artículo intenta precisar qué es el odio, deslindándolo de otros sentimientos como la ira y el resentimiento. A su vez, trata de examinar cómo está funcionando contemporáneamente el discurso del odio, cada vez de manera más abierta y desvergonzada, alentado por la xenofobia y por los fundamentalismos que se asientan en una visión conservadora del mundo; una visión que se niega a aceptar los cambios en las nociones de familia, género, etc. También señala cómo las redes sociales están propiciando dicho discurso o llevándolo hasta consecuencias donde pasa a ser un delito y las leyes pueden castigarlo.
No me diga “veci”: arqueología de un modo social
Authors: De Souza Thaisa
Published: January 2019

En la trastienda de las sociedades residen algunas verdades que se apartan de casi todo escrutinio empírico y conceptual. Sin ser su falta de inscripción simbólica ni su extraña configuración lo que las hace permanecer en esa especie de umbral, comparecen bajo la forma de propiedades ontológicas que finalmente establecen una circulación pulsional bastante específica. Ante uno de esos códigos inadvertidos de la cotidianidad colombiana —el apelativo “veci”—, hemos decidido colegir algunos vectores de análisis que, conjugando las vías psicoanalíticas y filosóficas, podrán situarnos ante nuevas conclusiones sobre el enlace sostenido de enemistad y violencia.
La construcción del enemigo interno. Una política pública del odio
Authors: Rincón Oñate Carlos Alberto
Published: January 2019

El llamado posacuerdo y la búsqueda de la paz han generado una situación nacional conflictiva pero urgente, en la que es necesario pensar en formas, metodologías y políticas que permitan la inclusión social. Sin embargo, tales procesos, que no son decretados por mandato presidencial, hacen preciso que la sociedad reconozca a ese otro que emerge bajo el significante “excombatiente”, tarea harto difícil porque en su historia, de manera sistemática, se le ha denominado “terrorista”. El texto presenta una ruta para reflexionar sobre algunos aspectos que intervienen en la construcción del otro y su tránsito al lugar de enemigo.

Learning English With Travel Blogs: A Genre-Based Process-Writing Teaching Proposal
Authors: Pascual Daniel
Published: January 2019

Current communication is increasingly computer-mediated, dynamic, dialogic, and global, so students should master new information, communication technologies, and digital genres, as well as acknowledge the global role of the English language. Thus, this paper aims to offer a teaching proposal, to be ideally implemented in the secondary education English as a foreign language classroom, on how to develop students’ communicative and digital competences based on a digital genre like the travel blog. First, a corpus of travel blogs was compiled, and the blogs’ communicative purposes and prominent linguistic and discursive features were identified. Next, different lesson plans were designed on the principles of communicative language teaching and task-based learning, together with the corpus-based results. Overall, students are expected to follow a process-writing approach that enables them to interact digitally in travel blogs.

Authors: Boldarine Amanda Chiarelo , Rosa Rodrigo Garcia
Published: January 2019

The purpose of this article is to explore and report some possible uses of corpus linguistics tools and techniques in a preparatory course for an international exam, focusing on helping students use corpora to find and analyze collocations and colligations when doing and creating multiplechoice cloze exercises. The participants were undergraduate students taking either a teacher training or a translation program. After discussing some research carried out on the pedagogical implications of using corpora, the article presents how a six-session preparatory course was designed and implemented, and the tools used to check participants’ perception of learning. The compiled data analyzed how participants reacted towards using an online corpus while getting themselves ready for the Use of English component of exams. The results demonstrated that corpus techniques were felt to be useful tools as far as fostering students’ autonomy was concerned. The study ends with a brief discussion on its limitations.
A arte da performance no desenvolvimento da produção oral em inglês
Authors: Mendes Nilton
Published: January 2019

The English teaching classroom can be the stage for different tasks for oral development. The artistic concept of performance for creating scenes for the practice of speaking in the classroom can put the student to reflect on the language choices that he makes during a task. Performance scenes can be moments of creation, risk, and experimentation with the language that lead the student to outcomes possibly not imagined by him initially. By creating opportunities for performance tasks for students to use the target language, students can be empowered to “go beyond themselves in order to become who they are by being who they are not” (Holzman, 1997), discovering new ways of negotiation and expression in another language.

Improving communication for learning with students: expectations, feedback and feedforward
Authors: Ley Tim , Kisielewska Jolanta , Collett Tracey , Burr Steven
Published: January 2019

This article was migrated. The article was marked as recommended. The aim of this paper is to draw together numerous strands from within the literature and our own practice to provide advice for improving communication about learning with students in undergraduate medical education. There is an assumption within higher education that assessment drives learning and, as such, assessment forms the focal points for communication between teachers and students. However, a broader approach is required to avoid misunderstandings and maximise the successful engagement with learning of everyone involved. It is important to plan a clear communication strategy that incorporates and enables identification with the unique values of the particular school. Where communication about learning is overtly discussed there are three main areas to consider: (1) management of expectations (sometimes referred to as feed up or feed in) that needs to include not only the use of authentic formative assessments, but also the viewpoints of both teachers and students. (2) Feedback and (3) Feedforward, both need to be considered from the perspectives of student and teacher. All communication needs to be inclusive, it's structures must provide scaffolding for respectful exchanges of information, and this will have clear practical consequences for the activities within the school.

Published: January 2019

RESUMO Objetivo Investigar os sintomas de transtorno de ansiedade social (TAS) entre os estudantes de Medicina do Centro Universitário Christus (Unichristus), instituição que adota o método de Aprendizagem Baseada em Problemas (ABP). Métodos Estudo transversal com 431 estudantes do primeiro ao quarto ano do curso de Medicina, por meio da aplicação da Escala de Ansiedade Social de Liebowitz (LSAS-SR), do Inventário de Ansiedade de Beck de Avaliação de Ansiedade, além de questionário com perguntas referentes a questões sociodemográficas, história familiar de doenças psiquiátricas, acompanhamento psicoterápico e psiquiátrico, nível de ansiedade para se expressar na tutoria e percepção de como a ansiedade variou ao longo dos semestres da faculdade. Resultados Utilizando-se a LSAS-SR como instrumento de triagem para casos de TAS, encontraram-se escores sugestivos do transtorno em 59,2% (255) dos estudantes. Em relação ao nível de ansiedade, o Inventário de Ansiedade de Beck (BAI) evidenciou que 59,3% (258) dos estudantes apresentaram nível de ansiedade mínimo; 26,6% (115), nível leve; 9,7% (42), nível moderado; e 4,4% (19), nível grave. Observou-se uma correlação significativa entre os escores obtidos nas escalas BAI e LSAS-SR: estudantes com sintomas sugestivos de ansiedade social apresentaram maior grau de ansiedade. Além disso, estudantes com sintomas de ansiedade social relataram maior nível de ansiedade para se expressar durante as sessões de tutoria. Conclusão A elevada prevalência de TAS apontada nesta investigação já justifica o estímulo à adoção de medidas psicoeducativas e estratégias pedagógicas que venham a auxiliar os estudantes com manifestações de ansiedade social a reduzir esses sintomas, favorecendo o processo de ensino-aprendizagem.

Published: January 2019

The search for solution was made in the article to raise the efficiency of the open-type local exhaust and to decrease the dust losses by the closed-type local exhaust-hood into the aspiration system at the expense of the vertical rotating exhaust cylinder. The exhaust is regarded in the form of the slit-type gaps parallel to the z-axes with the drain from the end of the cylinder. The improvements are proposed for the rotating cylinder to increase the air flow entrainment efficiency. The results obtained can be useful when designing of the dust-collecting chambers-capable aspiration hoods.

The comparative investigation on the ablation transformations were carried out for the phenolformaldehyde resin composites on base of silica fabric and hollow corundum micro spheres. It was establish that the corundum micro spheres addition lead to the composite's heat conductivity reduction. As a result the temperature increased at the exposed spot, the linear erosion rate increased by the factor of 2,7 and the coking front line decreased by a factor of 2,3. In the issue the ablation gave rise to the high-temperature mechanical and chemical erosion and these last in turn triggered the number of the serial-parallel chemical reactions with both the composite material porosity increasing and the creation of the hightemperature reaction products mainly the silicon carbide.Ill.9.

The rheological properties are described both for the initial (basic) HCBS of the composite bauxite and the same HCBS with 15 % SiC, as well as with the addition of 1 and 2 % of Si. The inﬂuence of the metal silicon addition was investigated, which decreased the sintering temperature and promoted the sealed porosity formation. It was established that in the materials containing Si addition, between the burning temperature of 1300‒1400 °C under the open porosity decreasing from 2,7 to 1,6 % the oxidation of SiC or Si can be slackened or inhibited. The dilatometric analysis showed that during the non-isothermal heating of the samples containing 10‒30 % of SiC, the certain degree of SiC oxidation can be noticed and the mullitization of the material became slower.

Published: January 2019

The current paper aims at investigating the stylistic constrains encounter the translators of the Holy Qura'n into English, through analysis and comparison, the incongruities and  disparities of meaning and style in translating the Qur'anic pragama- stylistic expressions into English, that is in the work of Mohammed Abdel Haleem, Pickthall and Mohammed Khan and Taj Al-Din Al-Hilalim (.http://www.aijcrnet.com/journal/index/1128.The study found that different translation strategies could lead to different translated versions of the same Qur'anic pragama-stylistics. Also, Qur'anic pragma-stylistic differences between Arabic and English languages seem to give rise to mistranslations as far as the religious text of Qur'anic texts. It is hoped that the study will cast new light on  main important idea that  the translators of the Holy Qur'an should consult the main books of exegesis, linguistics, philosophy, intertextuality, jurisprudence and history, etc., when he/she tries to render the Qur'anic prgama-stylistics.

Introduction: An increasing number of people suffer from degenerative diseases of the hip joints. Many studies report the long-term outcomes of invasive therapy in the treatment of coxarthrosis. However, results of prolonged conservative treatment are scarce. The purpose of this study was to evaluate the effects of prolonged conservative physical therapy on functional recovery of degenerative hip changes.

Methods: We retrospectively analyzed 47 patients diagnosed with coxarthrosis according to the American College of Rheumatology criteria. Data on sex and age, duration of physical therapy, the type of physical therapy, the values of manual muscle test (MMT) at admission and discharge, were taken from the medical records of the patients.

Results: There were 76.6% female and 23.4% male patients. Half of the patients were 70 or more years old. Majority of patients were treated by kinesiotherapy (74.5%) and had significantly different (p < 0.05) values of MMT at admission and discharge. Duration of treatment was 10-20 days for 23.4% of patients, while 29.8% received treatment for 31-40 days.

Conclusion: According to our results, MMT significantly improved at the end of the treatment. Thus, physical therapy had a positive effect on the recovery of muscle strength in patients with coxarthrosis.

Published: January 2019

Renal cell carcinoma (RCC) ranks first in mortality among urogenital tumors and is the most common disease after prostate and bladder cancer. Early detection of RCC allows immediately undertaking appropriate treatment, which significantly increases the survival of patients. In the case of the asymptomatic RCC, timely diagnosis in the early stages is usually difficult. To date, the problem of searching for molecular markers of clear cell RCC, which allows to determine the stage, metastatic potential and prognosis of disease, or select a treatment regimen remains topical. Of particular interest are early-stage biomarkers of RCC and its metastatic potential, as well as markers that can be obtained by non-invasive or minimally invasive methods. This review presents modern methods for diagnosing RCC using biomarkers.

Main Lines of Chinese Foreign Policy from the Opening to the Present
Authors: Martín Rafael
Published: January 2019

The history of the international relations of the People’s Republic of China contains lines of action that should not go unnoticed. These lines are the consequence of the extraordinary circumstances that have surrounded the country since its proclamation in 1949, then within the framework of the Cold War, but with a huge burden of personality and ideology. Chinese history and culture, thus, have shaped their own context from which the events that took place around them were understood. The energetic personality of Mao and his ideology, the pragmatism of Deng Xiaoping, and the vicissitudes experienced by the world from the Cold War to the present, have created a cosmos of diverse circumstances that nevertheless do not detract from the fact that Chinese diplomacy has wellmarked lines of action, flexible, but immutable in time, and which are typical of their personality and idiosyncrasy. To understand the international relations of a country is to understand the soul of its citizens, because this is often reflected in the others. China has lived these years its inclusion in the new global world without forgetting thepatterns that were already recognizable in distant times.

Published: January 2019

Background: Atrial fibrillation is one of most common arrhythmias observed in general practice. Atrial fibrillation may occur paroxysmal or may become established as permanent condition. The aim of the treatment of atrial fibrillation is either normalization of rhythm by cardioversion or control of ventricular rate by drugs. The present work was undertaken to study, clinical presentation, aetiology and complications in patients developing atrial fibrillation.Methods: A prospective study carried out at Department of Medicine V.M. Medical college and Shri Chhatrapati Shivaji Maharaj Sarvopachar Rungnalaya, Solapur, over the study period of two years. 100 patients of atrial fibrillation diagnosed by following clinical and ECG criteria were included. Detail study of aetiology complication and clinical presentation of atrial fibrillation was done in present study.Results: Commonest presenting symptom was breathlessness (70%) followed by palpitation (58%). Common signs elicited were irregular pulse, apex pulse deficit (92%). Congestive cardiac failure was present in 46% patient among those raised JVP was seen in 100% cases, oedema in 60.8% hepatomegaly 63.04% basal crepitations in 86.9% cases. ECG revealed coarse fibrillary waves (81.8%) in patients with rheumatic heart disease whereas fine fibrillary waves were seen in patients with IHD as cause of AF.Conclusions: Size of fibrillary was may be predicted etiology of AF as coarse waves are common in rheumatic and fine waves in non- rheumatic AF. The present paper would help in early diagnosis and prompt treatment of AF.
Dificultades y contradicciones en la construcción del socialismo en Cuba al inicio del periodo revolucionario
Authors: Sovilla Bruno
Published: January 2019

En este trabajo pretendemos demostrar que las dificultades económicas al inicio del periodo revolucionario radicaron inicialmente en una estrategia de desarrollo mal diseñada, y sucesivamente en la implementación de un sistema de dirección de la economía que prescindía no solo del mercado, sino también de los principios del cálculo económico, a la base de la planificación centralizada. Después de analizar la información estadística oficial y el debate que tuvo lugar en Cuba a mitad de los años 60 sobre el sistema de dirección más adecuado para una economía en vías de desarrollo en la construcción del socialismo, concluimos que la entera década se caracterizó por una dirección voluntarista de la economía, y solo el generoso apoyo de los países socialistas mantuvo en vida la revolución.
Novel Approaches for Efficient Delivery of Tyrosine Kinase Inhibitors
Authors: Moradpour Zahra , Barghi Leila
Published: January 2019

Epidermal growth factor receptors (EGFRs) have potential to be considered as therapeutic target for cancer treatment especially in cancer patients with overexpression of EGFR. Cetuximab as a first monoclonal antibody and Imatinib as the first small molecule tyrosine kinase inhibitor (SMTKI) were approved by FDA in 1998 and 2001. About 28 SMTKIs have been approved until 2015 and a large number of compound with kinase inhibitory activity are at the different phases of clinical trials. Although Kinase inhibitors target specific intracellular pathways, their tissue or cellular distribution are not specific. So treatment with these drugs causes serious dose dependent side effects. Targeted delivery of kinase inhibitors via dendrimers, polymeric nanoparticles, magnetic nanoparticles and lipid based delivery systems such as liposomes, solid lipid nanoparticles (SLN) and nanostructured lipid carriers (NLC) can lead to reduction of side effects and improving therapeutic efficacy of the drugs in the target organs. Furthermore formulation of these drugs is challenged by their physicochemical properties such as solubility and dissolution rate. The main approaches in order to increase dissolution rate, are particle size reduction, self-emulsification, cyclodextrin complexation, crystal modification and amorphous solid dispersion. Synergistic therapeutic effect, decreased side effects and drug resistant, reduced cost and increased patient compliance are the advantages associated with using combination therapy especially in the treatment of cancer. Combination of TKIs with chemotherapeutic agents or biopharmaceuticals such as monoclonal antibodies and oligonucleotides and also combination of two TKIs within one formulation is possible by new targeting delivery systems. This article reviews the recent advances in the design and development of delivery systems for TKIs.
