Abstract: radiogenic proctitis is a frequent complication of therapeutic radiation at the pelvic region. the aim of this study was to determine the efficacy of the epidermal growth factor (egf) in treating patients with proctitis as a complication of radiotherapy of gynecological tumors. a phase ii, placebo-controlled, randomized, double blind clinical trial was carried out. the treatment groups were: a) a solution of human recombinant epidermal growth factor (10 μg/ ml) in carboxymethyl cellulose or b) placebo (carboxymethylcellulose solution alone); the treatment was administered as a retention enema (20 ml) twice a day after bowel movement for 6 months. we included women of 18-75 years of age with proctitis as a complication of an ionizing radiation treatment of gynecological malignant tumors, confirmed by endoscopy, who gave their consent to participate. thirty-seven patients were included. the basic demographic variables and were homogeneous among groups, which were comparable. there were more responses in group a (egf) than in the control (placebo), but the difference was not statistically significant. considering only those patients who completed the treatment, the difference in response was greater with egf (86% vs 60%). the symptoms disappeared more rapidly in the group treatedwith egf (p=0.027 and p=0.016, for bleeding and tenesmus, respectively). the product under study was well tolerated. although there are signs of improvement in some symptoms, the sample was too small to demonstrate the effectiveness of hebervis in the treatment of proctitis.

Salud mental , 2008,
Abstract: El consumo de tabaco es considerado un problema de salud pública en todo el mundo debido a la cantidad de enfermedades y muertes relacionadas con su uso. La Organización Mundial de la Salud (OMS) reporta que 30% de los adultos son fumadores y, de éstos, aproximadamente cinco millones de personas morirán en un a o. También se estima que para 2020 habrá 8.4 millones de muertes anuales por enfermedades relacionadas con el consumo de tabaco, de las cuales siete de cada 10 ocurrirán en países en vías de desarrollo, como México, donde más de 53 mil personas fumadoras mueren al a o por enfermedades asociadas al tabaquismo y al menos 147 personas mueren diariamente. Por otro lado, en la bibliografía se ha encontrado que el da o en el organismo por fumar comienza desde el primer cigarro, que a los 10 a os se presentan síntomas sutiles en la función pulmonar y disminución de la tolerancia al ejercicio, y que es entre 20 y 30 a os después cuando los síntomas hacen a un fumador tomar conciencia del da o a su salud. En cuanto a la relación entre el uso de tabaco y la salud mental, ésta se evidencia por las consecuencias emocionales que conlleva padecer una enfermedad crónica. En este contexto, el objetivo del presente trabajo fue conocer la relación de problemas emocionales y malestares físicos con el consumo de tabaco en hombres trabajadores de una empresa textil mexicana

Abstract: introduction tobacco use is considered a worldwide public health problem because of the amount of death and disease it causes. the who reports that 30% of the adult population in the world are cigarette smokers, and that nearly five million of these will die within one year. prospective studies performed by the who show that if current tobacco use continues, in 2020 there will be 8.4 million deaths due to tobacco-related diseases every year; seven out of 10 of these deaths will occur in emergent countries, like mexico. more than 53000 tobacco users die every year in mexico because of tobacco-related diseases, and at least 147 of these die daily. data from the national addictions survey (nas) 2002 showed that 26.4% of the people between 12 and 65 years old were active tobacco consumers; this amounted to nearly 14 million individuals. of these, 7.1% were under 18 years old. the number of tobacco consumers in mexico has increased from nine million in 1988 to 14 million in 2002. according to the nas, 52% of the users smoke on a daily basis, and 61.4% of them began smoking when they were minors. to know the actual consumption levels, it is important to consider some factors: the number of cigarettes a person smokes, the different situations where a person smokes, and the social and physical consequences of smoking. thus, it would be possible to develop a consumer classification (i. e. soft consumers, mild consumers, and hard consumers). there may be numerous causes for a person to be ill. when speaking about the harmful effects of tobacco use, the literature is clear in stating that these begin with the first cigarette smoked. however, it can take up to 30 years for a consumer to notice the damage on his health after his/her consumption began; but within the first ten years there are problems in lung function and in physical endurance. when a person starts smoking there are acute and unpleasant side effects that are rarely associated with smoked tobacco use. consumption
Patrones de vientos troposféricos en la cuenca del Lago de Maracaibo, Venezuela
Jorge López,Rigoberto Andressen L.,Arnaldo Lugo
Terra Nueva Etapa , 2010,
Abstract: Se estudió el patrón de vientos en la baja tropósfera, en los sectores meridional y oriental de la cuenca del Lago de Maracaibo utilizando globospilotos, durante el período abril-mayo de 2004. Los lanzamientos se hicieron desde las localidades de El Chivo (08o 56 22" N., 71o 37' 47" O., 23 msnm), Mene Grande (09o 49' 00" N., 70o 56' 00" O., 27 msnm) y La Ca ada (10o 34' 00" N., 71o 44' 00" O., 66 msnm). Los períodos de lanzamiento se dividieron en matutinos y vespertinos con el fin de precisar las diferencias en los flujos meridionales y zonales en diferentes períodos del día. Estos flujos fueron obtenidos para diferentes alturas en cada lanzamiento, mediante el software Corrige de la Administración Nacional de Atmósfera y Océanos de Estados Unidos (NOAA) y fueron promediados para los tres días de lanzamientos. El ciclo diurno y el efecto de brisa lago-tierra se pudieron observar en la localidad de Mene Grande y, parcialmente, en la localidad de El Chivo. En la localidad de la Ca ada, ubicada en el extremo norte de la cuenca, el aumento de la velocidad del viento con la altura fue el aspecto más resaltante.

Avalia??o: Revista da Avalia??o da Educa??o Superior (Campinas) , 2009, DOI: 10.1590/S1414-40772009000300002
Abstract: during the past decade, the world bank's higher education guidelines were geared towards competition and the market place, while unesco reaffirmed the statute of its public service and advocated the importance of state financing, with the purpose of developing a higher education that is equally accessible to all and based on merit. this article is a comparison of international higher education. it presents considerations on the following topics: main global tendencies for higher education; world models of financing; global vision of university financing; financing, higher education policies, international cooperation and internationalization; higher education financing in europe. in short, it concludes that diversifying the sources of financing is both positive and necessary, though this must not imply a reduction or abdication of the state in the financing of higher education.

Karl Popper Y Friedrich Hayek: una luz sobre la naturaleza, objeto y método de la administración
Francisco López Gallego
Ecos de Economía , 2007,
Abstract: Con base en el reconocimiento de la existencia de un conocimiento objetivo sin sujeto cognoscente, propio del llamado “tercer mundo” poperiano, en primera instancia se intenta someter a examen el discurso administrativo –en tanto sistema de conocimientos– para determinar hasta qué punto es susceptible de ser construido mediante un método válido, con lo cual se aspira a establecer una discusión en torno a su naturaleza. En un segundo momento, se continúa con la presentación del método que Popper reclama para las ciencias sociales en general, devenido de la economía, el cual sería también el apropiado para nuestra disciplina. Finalmente, se pretende delimitar un objeto de estudio propio de dicho sistema de conocimientos, a partir de la diferencia que F. Hayek establece entre los órdenes sociales artificiales y espontáneos.
