Abstract: the infectious theory to explain atherosclerosis has allowed researchers to advance quickly on the knowledge about pathogenia of cardiovascular disease. even more, the concept of coronary disease as an inflammatory disease has developed new pathways for investigating the ischaemic cardiac. recent investigations suggest that the use of inflammatory markers may help for early detecting patients who present high risk of cardiovascular strokes appearance. also, epidemiological essays have revealed that periodontitis is a risk factor for cardiovascular disease to develop. periodontitis is a source of bacterias or their wastes, and provoke a hyperinflammatory response on the hostage, liberating cytokines for long periods. due to chronicity of both cardiovascular and periodontal disease, they may have some similar ethilogycal ways.
Existe relación entre enfermedad cardiovascular y periodontitis? Are there relation between cardiovascular disease and periodontitis?

Abstract: La hipótesis infecciosa de la aterosclerosis ha permitido un rápido avance en el conocimiento sobre los mecanismos patogénicos de la enfermedad coronaria. Más aun, el concepto de la enfermedad coronaria como una enfermedad inflamatoria ha abierto nuevos caminos para la investigación en el campo de la cardiopatía isquémica. Estudios recientes han sugerido que el empleo de marcadores de inflamación ayudaría en la identificación de pacientes con alto riesgo de padecer eventos cardiovasculares. También los estudios epidemiológicos han implicado a la periodontitis como un factor de riesgo para el desarrollo de la enfermedad cardiovascular. La enfermedad periodontal proporciona una fuente de bacterias o de sus productos, y citoquinas de respuesta hiperinflamatoria del huésped por largos periodos de tiempo. Dada la cronicidad de la enfermedad cardiovascular y de la enfermedad periodontal probablemente comparten algunos caminos de común etiologia.

Aproximaciones teóricas en torno a la representación sindical
Menéndez,Nicolás Diana;
Gaceta Laboral , 2009,
Abstract: the objective of this article is to propose a theoretical treatment for labour union representation in the public sector. drawing on the work of important authors such as pierre bourdieu, ernesto laclau, alessandro pizzorno, klaus offe, etc, a theoretical trajectory is described from the most abstract concept of political representation to a specific kind of union representation displayed in the environment of the state. methodology is based on a bibliographical review of the previously mentioned authors and reflections on field work experience. conclusions indicate the need to approach labour union representation in the public sector as a special field that requires attention to its own particular aspects, which cannot and should not be omitted.
Aproximaciones teóricas en torno a la representación sindical Theoretical approaches to labor union representation
Nicolás Diana Menéndez
Gaceta Laboral , 2009,
Abstract: En el presente trabajo se propone un abordaje teórico sobre la representación sindical en general, y en el Estado en particular. A partir de los aportes de importantes autores como Pierre Bourdieu, Ernesto Laclau, Alessandro Pizzorno y Claus Offe, realizaremos un recorrido desde las concepciones más abstractas de la representación política, hasta la singularidad de un tipo de representación sindical: la que se despliega en el ámbito del Estado. El abordaje teórico está basado en la revisión bibliográfica de los autores mencionados, y en reflexiones a partir de la experiencia en el trabajo de campo. En las conclusiones se sostiene fundamentalmente, la necesidad de abordar la representación sindical en el sector público como un campo particular que, requiere la atención de aspectos que le son propios y no pueden, ni deben ser omitidos.

Fenotipos alfa-1 antitripsina en pacientes cubanos con artritis reumatoidea
Francisco Menéndez Alejo,Ibis Menéndez Alejo,Aracely Mederos Oviedo,Jesús Castro Marrero
Revista Cubana de Medicina , 1995,
Abstract: Se determinaron los fenotipos alfa-1-antitripsina en 35 pacientes adultos cubanos con artritis reumatoidea y se compararon con los de 50 individuos sanos que conformaron el grupo control. Hubo incremento significativo de los fenotipos no MM en pacientes con artritis reumatoidea con respecto al grupo control (p = 0,003). Las comparaciones entre ambos grupos de pacientes (MM y no MM) mostraron que la presencia del factor reumatoideo se asoció significativamente (p = 0,0273) en los MM y que la inflamación articular persistente (p = 0,04) y la ausencia de remisión al tratamiento con sales de oro (p = 0,001), a los no MM. Es probable que los individuos con fenotipos alfa-1-At no MM sean susceptibles a la artritis reumatoidea en nuestro medio y en casos con la enfermedad tales fenotipos deficientes pueden desempe ar un papel en la severidad inflamatoria y en la mala respuesta al tratamiento.

Characterization of Doped Amorphous Silicon Thin Films through the Investigation of Dopant Elements by Glow Discharge Spectrometry: A Correlation of Conductivity and Bandgap Energy Measurements
Pascal Sánchez,Olaya Lorenzo,Armando Menéndez,Jose Luis Menéndez,David Gomez,Rosario Pereiro,Beatriz Fernández
International Journal of Molecular Sciences , 2011, DOI: 10.3390/ijms12042200
Abstract: The determination of optical parameters, such as absorption and extinction coefficients, refractive index and the bandgap energy, is crucial to understand the behavior and final efficiency of thin film solar cells based on hydrogenated amorphous silicon (a-Si:H). The influence of small variations of the gas flow rates used for the preparation of the p-a-SiC:H layer on the bandgap energy, as well as on the dopant elements concentration, thickness and conductivity of the p-layer, is investigated in this work using several complementary techniques. UV-NIR spectrophotometry and ellipsometry were used for the determination of bandgap energies of four p-a-SiC:H thin films, prepared by using different B 2H 6 and SiH 4 fluxes (B 2H 6 from 12 sccm to 20 sccm and SiH 4 from 6 sccm to 10 sccm). Moreover, radiofrequency glow discharge optical emission spectrometry technique was used for depth profiling characterization of p-a-SiC:H thin films and valuable information about dopant elements concentration and distribution throughout the coating was found. Finally, a direct relationship between the conductivity of p-a-SiC:H thin films and the dopant elements concentration, particularly boron and carbon, was observed for the four selected samples.
Síndrome metabólico

Abstract: children's obesity is the main risk factor for adult obesity, as well as for the metabolic syndrome, type 2 diabetes mellitus and cardiovascular diseases, which reduce life quality and expectancy. the metabolic syndrome is a clinical diagnosis that identifies a population that has high risk of cardiovascular diseases. insulin resistance appears as the common link and the trigger factor of metabolic impairments, modulated by genetic and environmental circumstances. the metabolic syndrome can be found in children, but at present it isn't clearly defined. the international diabetes federation's (idf) criteria for children and adolescents are used the most because of their easy management; waist measurement is its principal component. an international definition is needed to be able to compare different studies, and until this isn't accomplished, it shouldn't be diagnosed in children less than 10 years.
Planeación estratégica: técnica gerencial aplicada en la administración pública
José Juan Menéndez Ramírez,Teresa Becerril Sánchez
Quivera , 2005,
Abstract: La revolución tecnológica e informativa es uno de los elementos que han dado forma a la nueva recomposición de las estructuras productivas y administrativas de las organizaciones privadas, en tal dimensión, que ha impuesto nuevos ritmos de producción, comercialización, distribución y consumo en el mundo entero, además de insertar a la administración pública en un contexto de competitividad, eficiencia y eficacia y la ha orillado a adoptar algunas de las técnicas empleadas en el ámbito privado a fin de dar respuesta satisfactoria a las presiones del mercado, de ahí que en este trabajo se aborde el fenómeno de adopción, adaptación y aplicación de técnicas gerenciales en la administración pública, para ello, se toma a la planeación estratégica como elemento ilustrativo.
