“Development of lymphoid cell culture system from Penaeus monodon and molecular approaches for its transformation

Unveiling the molecular and regulatory mechanisms that prevent in vitro transformation in shrimp remains elusive in the development of continuous cell lines, with an arduous history of over 25 years (Jayesh et al., 2012). Despite presenting challenges to researchers in developing a cell line, the billion dollar aquaculture industry is under viral threat. In addition, the regulatory mechanisms that prevent in vitro transformation and carcinoma in shrimps might provide new leads for the development of anti-ageing and anti-cancer interventions in human (Vogt, 2011) and in higher vertebrates. This highlights the importance of developing shrimp cell lines, to bring out effective prophylactics against shrimp viruses and for understanding the mechanism that induce cancer and ageing in human.. Advances in molecular biology and various gene transfer technologies for immortalization of cells have resulted in the development of hundreds of cell lines from insects and mammals, but yet not a single cell line has been developed from shrimp and other marine invertebrates. With this backdrop, the research described in this thesis attempted to develop molecular tools for induced in vitro transformation in lymphoid cells from Penaeus monodon and for the development of continuous cell lines using conventional and novel technologies to address the problems at cellular and molecular level.

A Study Of The Strength And Compressibility Characteristics Of Cochin Marine Clays

With the advent of urbanisation and consequent search for more and more habitable land, it was imperative that the large tracts of marine clays, considered inhabitable earlier, had to be reclaimed and developed. These marine clays, wellknown for its high compressibility and poor shear strength, posed numerous problems to the builders and Cochin was no exception. It is only less than a decade since active research work was initiated on marine clays in general and Cochin marine clays in particular. Eventhough some systematic studies are available on compressibility characteristics, attempts to study the shear strength aspects and development of techniques to improve it have been very limited. This work is an investigation on the consolidation and shear strength characteristics of Cochin marine clays including methods to improve the same

“Studies on the Biology, Morphometrics and Biochemical composition of the Ommastrephid squid, Sthenoteuthis oualaniensis (Lesson,1830) of the south west coast of India”

With the stabilization of world finfish catches in general, and the depletion of a number of fish stocks that used to support industrial-scale fisheries, increasing attention is now being paid, to the so-called unconventional marine resources, which include many species of cephalopods. One of such important cephalopod resource is the tropical Indo-Pacific pelagic oceanic squid Sthenoteuthis oualaniensis. It is the most abundant large sized squid in the Indo- Pacific region with an estimated biomass of 8-11 metric tons. However, its distribution, biology, life cycle and nutrient value in the south west coast of India are still poorly known. So any new information of this species in the waters off the south west coast of India has important scientific significance for effective and rational utilization of this Oceanic fishery resources, especially during the time of depletion of shallow water resources. In view of that this study investigated different aspects of the Sthenoteuthis oualaniensis, such as morphometry, growth, mortality, maturation, spawning, food, feeding and biochemical composition in the south west coast of India to understand its possible prospective importance for commercial fishing and management of its fishery

Multifactorial interaction of growth factors on Penaeus monodon lymphoid cells and the impact of IGFs in DNA synthesis and metabolic activity in vitro

Development of continuous cell lines from shrimp is essential to investigate viral pathogens. Unfortunately, there is no valid cell line developed from crustaceans in general and shrimps in particular to address this issue. Lack of information on the requirements of cells in vitro limits the success of developing a cell line, where the microenvironment of a cell culture, provided by the growthmedium, is of prime importance. Screening and optimization of growth medium components based on statistical experimental designs have been widely used for improving the efficacy of cell culture media. Accordingly, we applied Plackett–Burman design and response surface methodology to study multifactorial interactions between the growth factors in shrimp cell culture medium and to identify the most important ones for growth of lymphoid cell culture from Penaeus monodon. The statistical screening and optimization indicated that insulin like growth factor-I (IGF-I) and insulin like growth factor-II (IGF-II) at concentrations of 100 and 150 ng ml-1, respectively, could significantly influence the metabolic activity and DNA synthesis of the lymphoid cells. An increase of 53 % metabolic activity and 24.8 % DNA synthesis could be obtained, which suggested that IGF-I and IGFII had critical roles in metabolic activity and DNA synthesis of shrimp lymphoid cells

Opportunities and constraints of peri-urban buffalo and dairy cattle systems in Faisalabad, Punjab, Pakistan

In the big cities of Pakistan, peri-urban dairy production plays an important role for household income generation and the supply of milk and meat to the urban population. On the other hand, milk production in general, and peri-urban dairy production in particular, faces numerous problems that have been well known for decades. Peri-urban dairy producers have been especially neglected by politicians as well as non-government-organizations (NGOs). Against this background, a study in Pakistan’s third largest city, Faisalabad (Punjab Province), was carried out with the aims of gathering basic information, determining major constraints and identifying options for improvements of the peri-urban milk production systems. For data collection, 145 peri-urban households (HH) engaged in dairy production were interviewed face to face using a structured and pretested questionnaire with an interpreter. For analyses, HH were classified into three wealth groups according to their own perception. Thus, 38 HH were poor, 95 HH well off and 12 HH rich (26.2%, 65.5% and 8.3%, respectively). The richer the respondents perceived their HH, the more frequently they were actually in possession of high value HH assets like phones, bank accounts, motorbikes, tractors and cars. Although there was no difference between the wealth groups with respect to the number of HH members (about 10, range: 1 to 23), the educational level of the HH heads differed significantly: on average, heads of poor HH had followed education for 3 years, compared to 6 years for well off HH and 8 years for rich HH. About 40% of the poor and well off HH also had off-farm incomes, while the percentage was much higher - two thirds (67%) - for the rich HH. The majority of the HH were landless (62%); the rest (55 HH) possessed agricultural land from 0.1 to 10.1 ha (average 2.8 ha), where they were growing green fodder: maize, sorghum and pearl millet in summer; berseem, sugar cane and wheat were grown in winter. Dairy animals accounted for about 60% of the herds; the number of dairy animals per HH ranged from 2 to 50 buffaloes (Nili-Ravi breed) and from 0 to 20 cows (mostly crossbred, also Sahiwal). About 37% (n=54) of the HH did not keep cattle. About three quarters of the dairy animals were lactating. The majority of the people taking care of the animals were family workers; 17.3% were hired labourers (exclusively male), employed by 11 rich and 32 well off HH; none of the poor HH employed workers, but the percentages were 33.7% for the well off and 91.7% for the rich HH. The total number of workers increased significantly with increasing wealth (poor: 2.0; well off:2.5; rich: 3.4). Overall, 69 female labourers were recorded, making up 16.8% of employed workers and one fourth of the HH’s own labourers. Apparently, their only duty was to clean the animals´ living areas; only one of them was also watering and showering the animals. Poor HH relied more on female workers than the other two groups: 27.1% of the workers of poor HH were women, but only 14.8% and 6.8% of the labour force of well off and rich HH were female. Two thirds (70%) of the HH sold milk to dhodis (middlemen) and one third (35%) to neighbours; three HH (2%) did doorstep delivery and one HH (1%) had its own shop. The 91 HH keeping both species usually sold mixed milk (97%). Clients for mixed and pure buffalo milk were dhodis (78%, respectively 59%) and neighbours (28%, respectively 47%). The highest milk prices per liter (Pakistani Rupees, 100 PKR @ 0.8 Euro) were paid by alternative clients (44 PKR; 4 HH), followed by neighbours (40 PKR, 50 HH); dhodis paid lower prices (36 PKR, 99 HH). Prices for pure buffalo and mixed milk did not differ significantly. However, HH obtaining the maximum price from the respective clients for the respective type of milk got between 20% (mixed milk, alternative clients) and 68% (mixed milk, dhodi) more than HH fetching the minimum price. Some HH (19%) reported 7% higher prices for the current summer than the preceding winter. Amount of milk sold and distance from the HH to the city center did not influence milk prices. Respondents usually named problems that directly affected their income and that were directly and constantly visible to them, such as high costs, little space and fodder shortages. Other constraints that are only influencing their income indirectly, e.g. the relatively low genetic potential of their animals due to neglected breeding as well as the short- and long-term health problems correlated with imbalanced feeding and insufficient health care, were rarely named. The same accounts for problems accompanying improper dung management (storage, disposal, burning instead of recycling) for the environment and human health. Most of the named problems are linked to each other and should be addressed within the context of the entire system. Therefore, further research should focus on systematic investigations and improvement options, taking a holistic and interdisciplinary approach instead of only working in single fields. Concerted efforts of dairy farmers, researchers, NGOs and political decision makers are necessary to create an economic, ecological and social framework that allows dairy production to serve the entire society. For this, different improvement options should be tested in terms of their impact on environment and income of the farmers, as well as feasibility and sustainability in the peri-urban zones of Faisalabad.

La indeterminación judicial de la responsabilidad extracontractual del estado por <> del servicio en la función administrativa

El trabajo inquiere, examina y condena la concepción bíblico-antigua con el cual se ha pretendido acrisolar a las convenciones jurídicas bajo el estigma de la objetividad, especialmente en el contexto de la Responsabilidad Civil Extracontractual de la Administración Pública, contrastado con el débito acaecido una vez presente un juicio orgánico, esto es, la falla del servicio, supuesto extraído en el interactuar antitético de las autoridades públicas respecto de una obligación primaria de cuidado debido, esto es, una norma legal pre-constituida al momento de la actuación material o acto administrativo. Supuesta tal objetividad en la falla del servicio, una dicotomía se presupone en su contra, la elasticidad con que ésta teoría pretende amalgamar bajo unos mismos y nunca cambiantes elementos de imputación jurídica en manos del juez siempre una única responsabilidad en las autoridades públicas. Y por otro lado, la incidencia de la teoría en la praxis, pragmática que no deja de insinuar lo contrario, esto es, supone desavenencias inexpugnables en la aplicación de tales premisas supuestas objetivas. Luego, resultado de este cisma es la indeterminación en la concepción falla del servicio, como concepto que no conoce contornos definidos, lo cual ofrece como síntoma de su abstrusa constitución una espiritual-subjetiva aplicación, y un cuestionamiento ineludible ¿existen líneas jurisprudenciales cuando de responsabilidad extracontractual se trata, en particular, en la falla del servicio?

Terapias cognoscitivo comportamentales de tercera generación (terapia de aceptación y compromiso, terapia cognoscitivo comportamental basada en Mindfulness, Psicoterapia Analítica Funcional) para el manejo de la fibromialgia

La fibromialgia es un síndrome doloroso crónico de alta complejidad en su diagnóstico (que hasta la fecha es clínico) y en su manejo. Se caracteriza por la presencia simultánea de numerosos problemas psicológicos en los pacientes, de los cuales se reconoce su asociación con el síndrome pero no la direccionalidad de la asociación. En consecuencia, la atención de las personas que lo desarrollan requiere del despliegue de numerosos esfuerzos interdisciplinarios, con un alto fracaso terapéutico y una mayor cronificación de los síntomas. La Terapia Cognoscitivo Comportamental ha demostrado ser una valiosa herramienta para el abordaje eficaz de las necesidades afectivas, emocionales y comportamentales de esta población. En consecuencia, el presente trabajo de grado tuvo como objetivo realizar una revisión de la literatura hallada en las bases de datos especializadas, sobre la evidencia de las Terapias de Cognoscitivo Comportamentales de Tercera Generación en el manejo de la fibromialgia. Se seleccionaron tres de estas terapias, a saber: la Terapia de Aceptación y Compromiso (TAC), la Terapia Cognoscitiva Basada en Mindfulness (TCBM) y la Psicoterapia Analítica Funcional (PAF). En primer lugar se presenta un breve recorrido histórico de la Terapia Comportamental con el fin de apreciar las diferencias y las similitudes de la Terapia Comportamental en sus tres generaciones. Posteriormente se presenta cada una de las tres terapias seleccionadas, contextualizándolas en cuanto a sus objetivos y evidencia empírica en el campo de la Psicología de la Salud y en específico del dolor crónico y de la fibromialgia. Finalmente, se presentan algunas conclusiones generales y se discute sobre su eficacia y el papel del en estas, en especial para el manejo de la persona con fibromialgia.

Búsqueda sistemática de guías de práctica clínica en cuidados paliativos pediátricos

Actualmente se estima que más de 160.000 niños en todo el mundo son diagnosticados de cáncer cada año y esta cifra podría ser considerablemente superior debido que los datos en su mayoría son imprecisos (1), hay un gran número de niños que junto con sus familias deben hacer frente a las implicaciones del diagnóstico de cáncer o enfermedad terminal, del tratamiento y el pronóstico. En Colombia se viene practicando en los servicios de pediatría, sin embargo no se realiza bajo un protocolo establecido El objetivo de este trabajo fue realizar una búsqueda sistemática de Guías de Práctica Clínica en Cuidados Paliativos Pediátricos basadas en la evidencia en el mundo y evaluarlas mediante preguntas clínicas preestablecidas, y bajo la metodología GLIA indicada por el ministerio de protección social, teniendo en cuenta la realidad colombiana y los principios de accesibilidad, calidad y eficiencia consagrados en el Sistema General de Seguridad Social de Salud de Colombia, con el fin de identificar la mejor Guía de Práctica Clínica (GPC) para la población de la Fundación Cardioinfantil de Bogotá – Colombia. Como resultado de la búsqueda se obtuvieron 32 GPC en Cuidados Paliativos de los cuales 8 guías se relacionaban con la población objeto y solo 5 de las guías respondían a las preguntas clínicas. El informe se elaboró según la metodología PRISMA con el fin constituir una base de datos para posteriores estudios, realización de guías o la adaptación de guías basadas en la evidencia.

Big Data: Wrongs and Rights by Andrew Cormack (WAIS Seminar)

Abstract: Big Data has been characterised as a great economic opportunity and a massive threat to privacy. Both may be correct: the same technology can indeed be used in ways that are highly beneficial and those that are ethically intolerable, maybe even simultaneously. Using examples of how Big Data might be used in education - normally referred to as "learning analytics" - the seminar will discuss possible ethical and legal frameworks for Big Data, and how these might guide the development of technologies, processes and policies that can deliver the benefits of Big Data without the nightmares. Speaker Biography: Andrew Cormack is Chief Regulatory Adviser, Jisc Technologies. He joined the company in 1999 as head of the JANET-CERT and EuroCERT incident response teams. In his current role he concentrates on the security, policy and regulatory issues around the network and services that Janet provides to its customer universities and colleges. Previously he worked for Cardiff University running web and email services, and for NERC's Shipboard Computer Group. He has degrees in Mathematics, Humanities and Law.

Research plan discussion: The socio-technical construction of MOOCs and educator practices in HE

In this seminar slot, we will discuss Steve's research aims and plan. Massive open online courses (MOOCs) have received substantial coverage in mainstream sources, academic media, and scholarly journals, both negative and positive. Numerous articles have addressed their potential impact on Higher Education systems in general, and some have highlighted problems with the instructional quality of MOOCs, and the lack of attention to research from online learning and distance education literature in MOOC design. However, few studies have looked at the relationship between social change and the construction of MOOCs within higher education, particularly in terms of educator and learning designer practices. This study aims to use the analytical strategy of Socio-Technical Interaction Networks (STIN) to explore the extent to which MOOCs are socially shaped and their relationship to educator and learning designer practices. The study involves a multi-site case study of 3 UK MOOC-producing universities and aims to capture an empirically based, nuanced understanding of the extent to which MOOCs are socially constructed in particular contexts, and the social implications of MOOCs, especially among educators and learning designers.

Análisis funcional de los mecanismos de ocurrencia y factores personales y laborales implicados en los accidentes de trabajo con riesgo biológico en un hospital universitario de la ciudad de Bogotá; D.C. durante los años 2010 a 2012

Los accidentes con riesgo biológico de origen laboral, son aquellos que sufre un trabajador, ya sea por cuenta propia o ajena, como consecuencia de contactos accidentales con fluidos animales, vegetales o humanos, en el ambiente de trabajo o mientras ejecuta sus tareas como empleado. Estos accidentes no son eventos fortuitos y dependen fuertemente del comportamiento inseguro en el lugar de trabajo y de los factores del ambiente laboral. El análisis funcional es una técnica cognitivo-conductual que se basa en el estudio de la evidencia anterior disponible con el objetivo de identificar los mecanismos de ocurrencia y los factores laborales y personales inseguros relacionados con los accidentes y sus antecedentes y consecuentes. Objetivo general: Establecer los mecanismos de ocurrencia y factores personales y laborales asociados a los accidentes de trabajo con riesgo biológico reportados durante los años 2010 a 2012, con el fin de proponer estrategias de intervención para controlarlos y así aportar a un ambiente de trabajo seguro. Materiales y métodos: Se realizó un estudio descriptivo retrospectivo, mediante la revisión de los informes de los accidentes laborales con riesgo biológico reportados en el área de Salud Ocupacional de un hospital universitario de la ciudad de Bogota; D.C. en los años 2010 a 2012. Resultados: Se registraron 287 reportes de accidentes de trabajo con riesgo biológico que cumplieron con los criterios de selección. Se encontró una prevalencia en el sexo femenino en una relación de 3,6 : 1 y en el grupo de edad entre 18 y 35 años de 69%. Por ocupación, se reportaron 149 accidentes en el grupo de enfermería y 49 accidentes en el grupo de servicios generales, siendo los dos grupos de mayor incidencia. Así mismo, hubo mayor accidentalidad por objetos cortopunzantes, siendo las punciones las más frecuentes en un 82,2% de los casos, localizándose con mayor frecuencia en los dedos de las manos en un 70,73% de los casos. En cuanto a los mecanismos de ocurrencia, la mayoría se produjo durante el uso del objeto, seguido de los producidos por contacto con objetos dejados en lugares inapropiados y por inadecuada disposición de los desechos. La distribución según el determinante de ocurrencia fue para actos inseguros 68,3% de los casos, para condiciones inseguras 3,1% de los casos y finalmente en el 28,6% de los casos los accidentes fueron debidos a la combinación de ambos, encontrándose una relación estadísticamente significativa entre esta variable y la mayoría de las características de los accidentes (p<0,05). Conclusiones: La mayoría de los accidentes de trabajo con riesgo biológico reportados fueron consecuencia de actos inseguros de los trabajadores. Por lo que se propone establecer diferentes capacitaciones periódicas para los trabajadores, contribuyendo a la incorporación de actos seguros y coherentes con las tareas a desarrollar dentro de su puesto de trabajo, y la manera de actuar frente a situaciones riesgosas.

Conceptualization and therapeutic treatment of a compulsive gambling case by Functional Analysis and Acceptance and Commitment Therapy

A clinical case of compulsive gambling is exposed in this article. The subject’s playing behaviour had both positive and negative consequences. The subject tried to practice control over the urge to play. As shown in the functional analysis, the failure to control the urge despite the best efforts worsened the problem due to its negative consequences. A variation of acceptance and commitment therapy (ACT) was applied in order to break down the fight-surrender vicious circle of the playing behaviour. Two treatment strategies were agreed upon: acceptance of the fact that both playing and not playing had negatives consequences and commitment to one of these options despite its disadvantages. Finally, it is proposed that this acceptance and commitment therapy is a useful therapeutic process as it decreases the suffering subject and eliminates the problem: playing bahaviour.

Assessment of construct validity and reliability of the inventory of masculinity and femininity in adolescents and young adults Colombian

This study evaluated the construct validity and reliability of Femininity and Masculinity Inventory-Imafe (Lara, 1993), and calculated standardized punctuations for Colombian teenagers and young adults. Participants were 1527 male and female, between 15 and 42. The general and scale reliability was evaluated through Alfa and Guttmann coefficients, and the factor analysis was used to estimate the construct validity. Standardized punctuations were obtained for gender, since there were statistically significant differences for sex in the six scales of the instrument. The inventory presented reliability values that oscillated between .76 and .88, and the factorial analysis showed three factors coherent with the factors found in its original validation. Correlacional inter-scales analysis and sex-differences were theoretically consistent.

Quality of life and Chronic Obstructive Pulmonary Disease

The Chronic Obstructive Pulmonary Disease (COPD) has a progressive and irreversible character and it’s associated to the triad of dyspnea, exercise limitation and the evident deterioration of quality of life. In the United States the prevalence of COPD in adult population is approximately of 6% in men, and 1 to 3% in women and it’s the fourth cause of mortality by no transmissible chronic diseases. In 1993, the National Health Interview Surgery considered that 12 millions of Americans suffer from chronic bronchitis and 2 million had emphysema. These two affections are responsible for more than 13% of the hospitalizations. As this affection progresses, patients experience a diminution in quality of life related to health (CVRS), their capacity to work get worse and their participation in physical and social activities reduces. Nevertheless, it has been confirmed that the isolated evaluation of COPD seriousness, defined by the reduction of the Forced Expiratory Volume in the First Second (FEV1), does not provide enough information to know the health state perceived by the patients. The fact that the CVRS is the result of the interaction of multiple physical, psychological and social factors, unique for each individual, can explain this finding. This paper is a general and updated approach to the integral handling of patients with COPD, and it discusses the concept of quality of life, related to health improvement.
