ABSTRACT
Alrededor del mundo y a lo largo de la historia, las personas han realizad y seguirán realizando actividades, acciones, prácticas y terapias, en su afán de contar con un mejor estado de salud enfermedad. Materiales y Métodos: Se buscaron artículos científicos principalmente en las bases de datos disponibles en el Sistema de Bibliotecas y Documentación de la Universidad de Costa Rica, además de otras fuentes de información, luego del análisis correspondiente se estructuró una comunicación que contempló tres grandes secciones: aspectos conceptuales, categorías terapéuticas y otros aspectos relacionados. Resultados: Se destaca que no existe un único concepto que englobe la diversidad de opciones existentes utilizadas. A disposición de la población existen más de 160 categorías terapéuticas, las cuales varían según el contexto social, cultural, geográfico, político, económico e ideológico en el que se desarrollan. Conclusión: Se necesita mayor consenso y participación de los entes involucrados en el tema, con miras a desarrollar sistemáticamente mayor evidencia científica que demuestre el potencial de todo el arsenal terapéutico que sea eficaz, efectivo, seguro y de calidad. Es necesaria una mayor regulación, educación formal e información dirigida a los diferentes actores involucrados en el uso de las distintas opciones terapéuticas con la finalidad de resguardar el bien común...
Around the world and throughout history, people have done, and will continue doing activities, actions, practices and therapies, in their eagerness to have a better health condition. Materials and Methods: Scientific articles were sought mainly in the databases available in the University Library System at the University of Costa Rica, and other sources of information, and then the analysis was structured for a communication which includes three main sections: conceptual, categories therapeutic and other related aspects. Results: Of the most important highlights that no single concept that encompasses the diversity of options used by people, available to the population there are more than 160 therapeutic categories, which vary according to the social, cultural, geographic, political, economic and ideological context in which they develop. Conclusion: Greater consensus is needed for and participation of the entities involved in the issue, in order to systematically develop further scientific evidence that demonstrates the potential of all therapeutic arsenal is efficient, effective, safe and quality. We need more regulation, formal education and information to different stakeholders in the use of different therapeutic options in order to safeguard the common good...

Cadmium sulfide (CdS) was in situ synthesized onto mesoporous TiO(2) films and used as a sensitizer to fabricate a photoelectrode for hydrogen generation in visible light. The incorporation of CdS extends the optical absorption threshold of a TiO(2) electrode to visible light, enhancing the visible-light-induced photocurrent. A maximum photoconversion efficiency of 3.67% was achieved for this CdS-sensitized TiO(2) electrode under visible light illumination of 100 mW cm(-2). The hydrogen generation rate obtained at conditions of maximum efficiency is 95.5 µmol cm(-2) h(-1). To the best of our knowledge, the hydrogen generation rate is the highest among those reported for a photoelectrochemical cell under the illumination of visible light.
ABSTRACT
AIM: To investigate the effects of anti-hCD154 McAb on inhibition of immune response. METHODS: The inhibitory effect of anti-hCD154 McAb on lymphocyte proliferation was evaluated by mixed lymphocyte reaction (MLR) and its effect on immune response was studied in severe combined immunodeficiency (SCID) mice reconstituted with human PBMC. RESULTS: (1) There were significant differences between experimental groups and control group in incorporation of -TdR into DNA (counts?min -1 ).Under dosages of 5 mg/L-50 mg/L, the incorporation of -TdR into DNA (counts?min -1 ) were decreased with dose increase. The value of counts?min -1 was peak when the dose was 100 mg/L.(2) The percentage of human T cell in SCID mice was lower in anti-hCD154-treatment groups compared with the control groups. (3) On day 3 after peripheral blood mononuclear cells(PBMC) grafted , human IgG were not detected by ELISA in all treatment groups. On day 7, 21, 31 after PBMC grafted, engrafted human PBMC produced human IgG in all treatment groups, but the mean amount of human IgG in SCID mice was markedly lower in the anti-hCD154-treated group compared with the control group. CONCLUSION: Our results show that anti-hCD154 McAb suppress human T cell proliferation and suppress human IgG production of human B cell transplanted in SCID mice.
