CONOCIMIENTO DE LOS ESTUDIANTES DE ENFERMERIA SOBRE VIH/SIDA
Dávila Maria Elena,Gil Maritza,Tagliaferro Zulay Antonieta
Salud, Arte y Cuidado , 2011,
Abstract: Amongst the health care professional, nurses and nursing students are an important component of the health care delivery system, due to frequent and prolonged contact with patients during their daily practice. With the purpose to determine the knowledge that nursing students have about HIV/AIDS, a descriptive investigation was conducted. The sample was represented by 50 students to whom a questionnaire with 20 questions about HIV/AIDS and mode of transmission was applied. The mean age of the participants was 21.30±1.31 and 98.0% were female. Four percent (4.0%) reported a “good” knowledge, 40.0% “fair”, and 56.0% “deficient” knowledge, respectively in relation to the diseases. Nine eight (98,0%) answered correctly that “ HIV/AIDS can be transmitted by sexual relations without protection”, 84.0% wrongly answer “ Lymphocytes T cells are the same as CD4 counts”, the same percentage was incorrectly answered with regard to the mode of transmission by corporal fluids. To the item “a woman can contaminate her baby trough lactation”, 26.0% answered incorrectly. Conclusions: In general the students have a “fair” knowledge. It is necessary to implement educational strategies to improve the knowledge about the disease, its consequences and preventive measures in order to protect this group at risk, which also have the responsibility to transmit information to their patients.
Bloco de constitucionalidade e princípios constitucionais: desafios do poder judiciário
Ana Maria D’ávila Lopes
Sequência : Estudos Juridicos e Politicos , 2009,
Abstract: A soberania do legislador, nos moldesideados nos séculos XVIII e XIX, tem cedidoespa o à supremacia da constitui o. O dogma dasepara o de poderes e a cega submiss o dos juízesà lei formal têm sido substituídos pela prevalênciados direitos fundamentais, cuja for a expansivafoi reconhecida na Constitui o Federal de 1988,ao incorporar a teoria do bloco de constitucionalidadenas suas linhas (art. 5o, §2o). No entanto, essainova o tem intensificado ainda mais os debatessobre a legitimidade dos juízes para a concretiza ode normas constitucionais abertas. Nessecontexto, o presente artigo objetiva discutir comoos juízes vêm enfrentado o desafio de concretizaros princípios constitucionais n o previstos notexto codificado da Constitui o, mas que, pelateoria do bloco, têm nível constitucional. Comessa finalidade, inicialmente será apresentada ateoria do bloco de constitucionalidade na Fran ae na Espanha, onde teve sua origem, para,seguidamente, evidenciar a existência de umbloco de constitucionalidade no direito brasileiro.Posteriormente, o papel dos juízes na concretiza odos princípios constitucionais será discutida.Finalmente, será analisada a principal jurisprudênciado Supremo Tribunal sobre a temática.The Parliament sovereignty, inits 18th and 19th century model, has beensubstituted by the constitution supremacy. Thedogma of separation of powers and the blindsubmission of judges to the written law hasbeen replaced by the prevalence of fundamentalrights, the expansive strength of which hasbeen recognized by the Federal Constitutionof 1988, by incorporating the constitutionalblock theory in its text (art. 5o, §2o). Thatinnovation has intensified the discussion aboutJudiciary legitimacy to concretize constitutionalprinciples. In that context, this paper aims todiscuss how judges are facing the challenge ofapplying constitutional principles, which are outof the constitution, but that have constitutionalhierarchy, because of the constitutional blocktheory. With that purpose, initially, it will bepresented the constitutional block theory inFrance and Spain, looking to demonstrate theexistence of a constitutional block in Brazilianlaw system. After that, it will be discussed therole of the judges to concretize constitutionalprinciples. Finally, it will be analyzed someimportant jurisprudence of the Federal SupremeCourt about those subjects had been analyzed.
Tools for information search: The MeSH terms
Diego Camps*,Yanina Recuero,Rodolfo Esteban ávila,Maria Elena Samar
MedUNAB , 2006,
Abstract: Medical Subject Headings or simply MeSH are the controlled vocabularyused by Medline and other databases to classify and processthe information stored in them. When we search by the descriptors,more precise results are obtained, and the information will probablybe more appropriate to the interests of the users. The objective ofthe present work is to develop a guide, to create in the readersabilities for the search of information in Medline from MeSH. Step I:Selection of subject, words or significant phrases, and their equivalences in English. Step II: Search map elaboration. Step III: Search execution. Step IV: Outline and refine the strategy and state results. Critical evaluation. Bibliographical databases constitute one of the main sources of publications. The use of modern tools to search information in the health professions, requires the creation of a new culture, centered in interactive self-learning.
EFECTO DE LA HUMEDAD, TEMPERATURA Y PH DEL SUELO EN LA ACTIVIDAD MICROBIANA A NIVEL DE LABORATORIO
Elena Ramos Vásquez,Doris Zú?iga Dávila
Ecología Aplicada , 2008,
Abstract: El presente estudio se realizó con la finalidad de evaluar bajo condiciones de laboratorio, la influencia de tres parámetros físico-químicos sobre la actividad microbiana en un suelo agrícola medida por la cuantificación de la producción de CO2 y actividad deshidrogenasa. Se realizaron por separado, tres ensayos para 4 porcentajes de humedad %(v/p): 5.0 %, 10.0 %, 15.0 % y 18.0 %; 4 temperaturas: 8.0 oC, 21.0 oC, 27.5 oC y 37.0 oC; y 4 valores de pH: 4.0, 6.1, 7.8 y 8.2. Cada ensayo de cuatro tratamientos y 4 repeticiones por tratamiento se condujo siguiendo los lineamientos del dise o completamente al azar (DCA). Los mayores valores de actividad microbiana [0.097 mg CO2·g-1·h-1 y 173.09 ug formazán·g-1·(24h)-1] se obtuvieron a 18% de humedad, en condiciones estándares de temperatura y pH; se encontró que la temperatura de 27.5oC era óptima para producción de CO2 [0.140 mg CO2·g-1·h-1] y 37.0 oC para la actividad deshidrogenasa [156.78 ug formazán·g-1·(24h)-1], en condiciones estándares de humedad relativa y pH; y se estableció como pH óptimo aquel cercano a la neutralidad (7.8) [0.055 mg CO2·g 1·h-1, 171.19 ug formazán·g-1·(24h)-1], en condiciones estándares de humedad relativa y temperatura.
EFECTO DE DIFERENTES INOCULANTES SOBRE LA ACTIVIDAD MICROBIANA EN LA RIZóSFERA DEL CULTIVO DE PALLAR (Phaseolus lunatus var. sieva) EN CONDICIONES DE CAMPO
Elena Ramos Vásquez,Doris Zú?iga Dávila
Ecología Aplicada , 2008,
Abstract: Se evaluó la actividad microbiana en la rizósfera de Phaseolus lunatus var. sieva, apartir de muestras de suelo colectadas en campo durante los diferentes estados fenológicos del cultivo, cuyas semillas fueron inoculadas con Bradyrhizobium sp. cepa PCYGIVN3, cepa PSNC4N2 y la interacción de éstas; además, se evaluó la aplicación de fertilizante nitrogenado N-P-K y el control sin inocular. Se determinaron la respiración y la actividad deshidrogenasa de los microorganismos en la rizósfera, las poblaciones microbianas y la materia seca vegetal de las plantas ensayadas. La mayor producción de CO2 se observó durante la floración. La respiración en la rizósfera inoculada con la interacción de cepas fue mayor que la cepa PSNC4N2 (0.121 y 0.088 mg CO2·g- 1·h-1 respectivamente); siendo la primera significativamente mayor respecto al testigo y al tratamiento químico nitrogenado [0.085 mg CO2·g-1·h-1] (p<0.1). La actividad deshidrogenasa de la rizósfera inoculada con Bradyrhizobium cepa PSNC4N2 > cepa PCYGIVN3 > interacción, con 61.04, 56.57 y 51.37 ug formazán·g-1·(24h)-1 respectivamente, evidenciando diferencias significativas con la fertilización química nitrogenada [40.87 ug formazán·g-1·(24h)-1]. Los valores más altos de actividad deshidrogenasa se registraron antes de la cosecha, probablemente por la influencia ambiental y la presencia de fitonemátodes en las raíces. La actividad microbiana se presentó como una técnica más sensible que el recuento de microorganismos y permitió unabuena correlación con los resultados de materia seca obtenidos en el tratamiento de la interacción de cepas de Bradyrhizobium y el inoculado con la cepa PSNC4N2, que presentaron los valores más altos de materia seca durante el periodo comprendido entre la floración y madurez de vainas.

Samar,Maria Elena; ávila,Rodolfo Esteban; Asis,Onell Gabriela; Fonseca,Ismael; Corball,Alberto;
International journal of odontostomatology , 2012, DOI: 10.4067/S0718-381X2012000100008
Abstract: the stroma plays an important rol in tumoral invasion and metastasis. type i collagen is the main structural component of the stroma in several tumors. however, there are few studies on salivary gland tumors. based on this background the objective of the present communication was to study collagen characteristics with picrosirius red/polarization on malignant and benign tumors of salivary glands to evaluate its posible rol in the tumoral progression mechanism. histological sections of pleomorphic adenoma, adenoid cystic carcinoma and epithelial/myoepithelial carcinoma were stained with h/e and picrosirius red and were studied with polarization microscope. collagen birefringence with picrosirius/polarization was different in the malignant tumor stroma (adenoid cystic carcinoma and epithelialmyoepithelial carcinoma), with predominance of type i collagen, compared with a benign tumor (pleomorphic adenoma), with predominance of type iii collagen. the different staining profile in collagen fibers produced in the benign and malignant stroma tumors analized could be related with different tumoral expansion mechanism, which were scarce studied on the salivary glands tumors. more studies are needed to obtain more conclusive results to contribute to diagnosis, prognosis and treatment.
Una nueva interpretación de la estratigrafía de la Región de Tolimán, Estado de Querétaro
Dávila Alcocer, Víctor M.;Centeno García, Elena;Valencia, Victor;Fitz D., Elisa;
Boletín de la Sociedad Geológica Mexicana , 2009,
Abstract: it is proposed in this note that the oldest terrigenous rocks cropping out in the tolimán region in the state of querétaro belong to two different units: el chilar complex and the san juan de la rosa formation. the first consists of highly deformed siliciclastic turbidites and the second is a volcano-sedimentary succession deposited in marine conditions. the volcanism of the san juan de la rosa formation is felsic in composition and late jurassic-early cretaceous in age. we postulate as a working hypothesis that the felsic magmatism of the san juan de la rosa formation are part of the jurassic volcanic arc in central mexico that migrated in time and space towards the south.
Determination of nitrofurazone in topical pharmaceutical preparations: comparison of the UV-Visible diffuse reflectance versus transmittance versus HPLC methods
Tubino, Matthieu;Vila, Marta Maria D. C.;Palumbo, Marcio N.;
Journal of the Brazilian Chemical Society , 2009, DOI: 10.1590/S0103-50532009001000019
Abstract: hlpc has been an important technique in the analysis of pharmaceutical principles in pharmaceutical preparations. sometimes, however, the use of this technique presumed to be more rapid, simple and reliable, is not the most adequate. in various cases simpler and more rapid methods can be used with clear advantages. in the present work the comparison of the quantitative results obtained with the hplc recommended method with those resulted from the uv-visible diffuse reflectance determination procedure and with the classical transmittance measurements of aqueous solutions was done. the experimental results of the three methods were compared through the statistical student's t test and agreement was observed at 95% confidence level. among them the diffuse uv-visible reflectance procedure is the simplest and the transmittance method offered the highest precision. the accuracy of the three methods is similar. a very interesting characteristic of the proposed reflectance method is that, despite the fact that it is quantitative, no weighing of aliquots is needed.
Direito à saúde, aten??o básica e transferências condicionadas de renda na América Latina
Fonseca,Ana Maria Medeiros da; Viana,Ana Luiza dvila;
Ciência & Saúde Coletiva , 2007, DOI: 10.1590/S1413-81232007000600012
Abstract: conditional cash transfer programs in latin america impose specific requirements and responsibilities on beneficiary households, in order to upgrade education levels, improve drop-out rates and eliminate child labor, while enhancing health and nutrition indicators. although counterpart healthcare conditions are common to all these programs, government strategies differ in terms of reaching their goals, at times even undermining improvements in the living conditions of more vulnerable segments of the population. instead of upholding rights to healthcare, such initiatives may well trigger a new cycle of tightly-focused basic care through provisional programs.
TIPOLOGIA URBANA: O EXEMPLO DO ESTADO DO RIO DE JANEIRO
Miguel Angelo RIBEIRO,Vera Maria dvila CAVALCANTI
Revista ACTA Geográfica , 2011,
Abstract: This article intends to analyze the fluminense spatial organization, based upon a typology that will contemplate the urbanization rate of the state's municipalities and comprises the indexes of demographic dimension and urbanization rate. Choosing demographic dimension allows for a discriminative interpretation of both consumption and production within a municipality, due to the elected variable (population) and its proximity to the actual bulk of consumers. As for the choice of urbanization rate, it lies upon the acknowledgement that the bigger the ratio of urban population the greater will be the expression of urban activity - commerce, services and industry. The methodology used in constructing such typology consisted in matrically crossing the values of population (demographic dimension) and of the ratio between the latter and the urban population (urbanization rate). Thus, these matrical crossings led to the identification of three major sets of municipalities: urban, in transition to urban and rural.
