Detec o da infec o pelo vírus da artrite-encefalite caprina: imunodifus o em ágar e rea o em cadeia da polimerase com "primers" degenerados

Abstract: O objetivo deste trabalho foi analisar amostras de soro e de células sangüíneas de caprinos para detec o de anticorpos e DNA proviral do vírus da artrite-encefalite caprina (CAEV), respectivamente. Utilizou-se a técnica de imunodifus o em ágar (AGID) e a rea o em cadeia da polimerase (PCR) com "primers" degenerados. Foram analisadas amostras de diferentes procedências: 39 de Mato Grosso do Sul (MS), 19 de S o Paulo (SP) e 22 do Ceará (CE), dessas últimas, 12 oriundas de animais importados do Canadá. Os resultados de AGID e PCR foram discordantes, pois o primeiro permitiu a detec o de 25 animais soropositivos, enquanto a PCR detectou DNA proviral de CAEV em 16 amostras. Pela PCR foi possível identificar animais infectados cujos testes sorológicos foram negativos pelo AGID: oito amostras do MS e um do CE. S o discutidos diferentes aspectos que poderiam estar envolvidos na discordancia dos resultados.

Abstract: the purpose of this work was to analyse serum and blood cells from caprine origin to detect antibody and proviral dna of caprine arthritis encephalitis virus (caev), respectively. agar gel immunodiffusion (agid) and polymerase chain reaction (pcr) with degenerated primers were used. samples of different geographical regions were analysed: 39 from mato grosso do sul (ms), 19 from s?o paulo (sp), 22 from ceará (ce) including 10 from canada (imported animals), providing a total of 80 samples. the results obtained by agid and pcr were discordants, as 25 samples were detected as seropositive, while 16 infected animals were detected by pcr. on the other hand, pcr allowed the identification of infected animals that did not have detectable antibodies by agid: eight samples from ms and one from ce. different aspects related to these discordant results are discussed.
Mineralogical Characterization and Beneficiation Studies of Pyrophyllite from Orissa, India  [PDF]
B. Das, J.K. Mohanty
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2009, DOI: 10.4236/jmmce.2009.84029
Abstract: Mineralogical and chemical analyses of three textural varieties of pyrophyllite samples collected from Baliadihi mine of Keonjhar district, Orissa, India are investigated. Mineralogically they consist of quartz, pyrophyllite, altered feldspar as major minerals and muscovite, chlorite, tourmaline, hematite etc. as minor minerals. The samples exhibit compositional variation of SiO2 65.56 - 71.66%, Al2O3 18.79- 22.94%, FeO 1.13- 1.68% and alkalis 3.24 to 6 %. Beneficiation studies using flotation technique has indicated that silica can be reduced with concomitant increase in alumina and brightness from a raw pyrophyllite sample which can be suitable for refractory purposes.
Health and Socio-Economic Factors as Determinants of Happiness and Life Satisfaction of People Living in Oke-Ogun Areas of Oyo State, Nigeria
J.K. Mojoyinola
Pakistan Journal of Social Sciences , 2012,
Abstract: The study investigated the impact of health and socio-economic factors on happiness and life satisfaction. Towards this end, a single questionnaire tagged "Happiness and Life Satisfaction Assessment Questionnaire (HALSAQ) was used as the major instrument for the study. A descriptive survey research design was adopted for the study and two hypotheses were tested, using the statistical tests of Analysis of Variance (ANOVA), Multiple Regression and Partial Correlation. The study established, among others, that there was no significant impact of health on happiness and life satisfaction, but that socio-economic factors had significant impact on happiness and life satisfaction. Based on the above findings, some recommendations were made, among which are that every person should strive to make him or herself happy, becomes educated, live a comfortable life, always remain healthy, engage in leisure activities and establish a small-scale business or find a good job to earn a living.
The role of endoscopy and endoscopic ultrasonography in the diagnosis of gastrointestinal neuroendocrine tumors
J.K. Triantafillidis .
Annals of Gastroenterology , 2007,
Abstract: SUMMARY Gastrointestinal neuroendocrine tumors are rare malignancies that have been classified by the peptides they secrete and the resulting clinical symptoms. They constitute less than 2% of all gastrointestinal cancers. Fifty percent of neuroendocrine tumors in clinical practice are the so-called carcinoid variety and are found incidentally at operation, after metastasis has occurred in the small intestine. Approximately 60% of pancreatic gastrinomas are concentrated in an area sub-tented by the head of the pancreas, gastric antrum, and first portion of the duodenum. The role of endoscopic techniques (upper GI endoscopy, push enteroscopy, and colonoscopy) in the diagnosis of endocrine gastrointestinal tumors seems to be quite important. Although there are no specific endoscopic features allowing the accurate and safe endoscopic diagnosis of an endocrine tumor, endoscopy could aid in the final diagnosis reached by identifying and removing the lesion or taking biopsies and sending them for histology. On the other hand, endoscopic ultrasonography, in experienced hands, not only visualizes the tumor itself but offers the ability to obtain smears for cytologic examination via fine needle aspiration. The invention of the wireless capsule which transfers high quality endoscopic pictures of the whole small bowel, will probably replace the classical small bowel barium followthrough in patients with suspected small bowel endocrine tumor. Key words: Neuroendocrine tumors, Endoscopy, Gastrointestinal hormones

Collagenous colitis: Recent developments
J.K. Triantafillidis .
Annals of Gastroenterology , 2007,
Abstract: SUMMARY Collagenous colitis and lymphocytic colitis are two chronic inflammatory conditions, involving the large bowel. These two interesting entities, are usually referred to under the general term microscopic colitis. Collagenous colitis is characterized by watery diarrhea, abdominal bloating and mild loss of weight. The true incidence is unknown. However, it has been estimated that it is unlikely to exceed one case per 100000 population. The etiology is unknown, although the use of non-steroidal anti-inflammatory drugs and lansoprazole, as well as infection by Yersinia enterocolitica have been implicated in the pathogenesis of the disease. The role of activated eosinophils seems to be quite important. Diagnosis requires the histological detection of a thick subepithelial collagen band on large bowel mucosa biopsies. Treatment includes the administration of mesalamine, corticosteroids, budesonide, cholestyramine, as well as methotrexate, pendoxyphylline and octeotride. Surgery is reserved for severe cases. The course of the disease seems to be quite benign. Although most patients relapse after treatment cessation, most are asymptomatic for a long period of time after the establishment of diagnosis. Progression to ulcerative colitis occurs although in only a small percentage of patients. Fortunately no association with intestinal or extraintestinal cancers has been found. Key words: Collagenous colitis, Inflammatory bowel disease, Microscopic colitis, Lymphocytic colitis

Think Tank Participation in Discerning Security Issues: The US Experience
Alyson J.K. Bailes
Revista CIDOB d'Afers Internacionals , 1997,
Abstract: El final de la Guerra Fría también implicó el fin de cierta ventaja comparativa que tenían algunos think tanks privados en Estados Unidos respecto al impacto de sus trabajos en las políticas de seguridad del gobierno. La autora examina los nuevos actores y circunstanciasimplicados en el juego político actual y se ala algunos factores importantes para la supervivencia de los think tanks en el próximo siglo. En su análisis, la autora se centra en dos casos –la ampliación de la OTAN y la situación de Bosnia– que considera ejemplos de la actual interacción entre lo público y lo privado –con referencia a las políticas de seguridad. Esta interacción se caracteriza por la limitación de recursos, la imperfección de la información, la actitud distante y atrincherada de las burocracias y la complejidad y lo imprevisible de los procesos. En este sentido, en lugar de buscar influencia sobre los Gobiernos, legisladores, opinión pública, los think tanks debieran atender al impacto de sus productos:la calidad del mensaje, el grado de éxito en definir y alcanzar la audiencia adecuada, y el nivel de receptividad de ésta. Es decir, si los think tanks quieren ser importantes, han de inventarse una estrategia para adaptarse a un medio internacional en el que los políticos con poder de decisión conviven con fenómenos transnacionales y asumir una nueva corresponsabilidad entre lo público y lo privado.
