    Durante el proceso de universalizaci√≥n se adoptan distintas formas de organizaci√≥n de la ense√Īanza (FOE), siendo la principal la Educaci√≥n en el Trabajo. El pase de visita en la comunidad es una modalidad de esta en los nuevos escenarios, debe ser preparada, organizada y dirigida por el profesor integral del consultorio. Se puede realizar en el PPU, domicilio, hogares maternos y de ancianos. Consta de varias etapas: organizaci√≥n exhaustiva de la actividad, etapa previa (estudio individual, recolecci√≥n de datos, m√©todo cl√≠nico), presentaci√≥n del paciente, (contexto familiar e higi√©nico-epidemiol√≥gico), an√°lisis colectivo (pir√°mide docente), conclusiones (eval√ļa, corrige, motiva, esclarece, demuestra, orienta, aporta, enfatiza y comprueba), estudio individual y autoaprendizaje. Esta actividad desarrollada en la Atenci√≥n Primaria de Salud con estas caracter√≠sticas, ha logrado integrar los aspectos cl√≠nicos, ambientales, familiares e higi√©nicos-epidemiol√≥gicos donde se desenvuelve el paciente. Palabras clave: ATENCI√ďN PRIMARIA DE SALUD, DESARROLLO DE LA COMUNIDAD. ABSTRACT During the universalization process different forms of organizing learning process are introduced, being Education in Work the most important. Medical rounds in the community is a modality in the new contexts, the rounds must be prepared, organized and directed by the comprehensive professor of the Doctor's Office. The medical rounds can be conducted in the University Polyclinic, houses, maternal and old people's homes; having several stages: an exhaustive organization of the activity, a previous preparation (individual study, collection of data, clinical method), patient's presentation (familial and hygienic-epidemiologic context), collective analysis (teaching pyramid), conclusions (evaluate, correct, encourage, elucidate, demonstrate, advise, contribute, emphasize and confirm), individual study and self-learning. This activity, having these characteristics in Primary Health Care, facilitates the integration of the clinical, environmental, familial and hygienic-epidemiologic aspects where the patient becomes involve. Key words: Primary Health Care, community development

    Using high rate algal ponds for wastewater treatment

    Many systems have been proposed for the decontamination of domestic and industrial wastewater and leachates. It is currently expected to treat wastewater and derive economic and environmental benefit. It is in this context that high rate algal systems (HRAPs) were originally proposed for the treatment of domestic wastewater. However, the research around this technology has shown advantages and benefits that were not initially contemplated. Actually, deployments are being made for the treatment of wastewater, seeking the production of biofuels, algal biomass for food (animal and human), obtaining pharmaceuticals and bioprospecting of algae. In addition to this, research on the capture and reduction of carbon dioxide (CO2), specific mechanisms for pollutant removal and Hydrobio- logy optimization of the system is being done. However, there is a lack of necessary information about the function and ecology of algae, the relationship algae/bacteria, the effect of hydrodynamic performance of the pond on algal production, the effect of the tropical environmental variables on the performance of the system and the developing of design standards for tropical zones.Se han propuesto muchos sistemas para la descontaminaci√≥n de las aguas residuales dom√©sticas, industriales y lixiviados. Actualmente se espera tratar las aguas residuales y derivar un beneficio econ√≥mico-ambiental. Es en este contexto que los sistemas algales de alta tasa se propusieron inicialmente para el tratamiento de aguas residuales dom√©sticas. Sin em- bargo, la investigaci√≥n realizada alrededor de esta tecnolog√≠a ha mostrado ventajas y beneficios que no se ten√≠an contemplados inicialmente. En la actualidad se est√°n realizando implementaciones en el tratamiento de las aguas residuales, buscando la producci√≥n de biocombustibles, bio- masa algal para alimento (animal y humano), la obtenci√≥n de productos farmac√©uticos y la bioprospecci√≥n de las algas. Adicional a esto, se est√° investigando sobre la captura y reducci√≥n del di√≥xido de carbono (CO2) atmosf√©rico, mecanismos de eliminaci√≥n de contaminantes espec√≠ficos y la optimizaci√≥n de la hidrobiolog√≠a del sistema. Sin embargo, hace falta informaci√≥n sobre la funci√≥n y la ecolog√≠a de las algas y la relaci√≥n alga/ bacteria, efecto del comportamiento hidrodin√°mico de la laguna sobre la producci√≥n algal, el efecto de las variables ambientales del tr√≥pico en el desempe√Īo del sistema y el desarrollo de criterios de dise√Īo para zonas tropicales

    Yessotoxin, a Marine Toxin, Exhibits Anti-Allergic and Anti-Tumoural Activities Inhibiting Melanoma Tumour Growth in a Preclinical Model.

    Yessotoxins (YTXs) are a group of marine toxins produced by the dinoflagellates Protoceratium reticulatum, Lingulodinium polyedrum and Gonyaulax spinifera. They may have medical interest due to their potential role as anti-allergic but also anti-cancer compounds. However, their biological activities remain poorly characterized. Here, we show that the small molecular compound YTX causes a slight but significant reduction of the ability of mast cells to degranulate. Strikingly, further examination revealed that YTX had a marked and selective cytotoxicity for the RBL-2H3 mast cell line inducing apoptosis, while primary bone marrow derived mast cells were highly resistant. In addition, YTX exhibited strong cytotoxicity against the human B-chronic lymphocytic leukaemia cell line MEC1 and the murine melanoma cell line B16F10. To analyse the potential role of YTX as an anti-cancer drug in vivo we used the well-established B16F10 melanoma preclinical mouse model. Our results demonstrate that a few local application of YTX around established tumours dramatically diminished tumour growth in the absence of any significant toxicity as determined by the absence of weight loss and haematological alterations. Our data support that YTX may have a minor role as an anti-allergic drug, but reveals an important potential for its use as an anti-cancer drug

    The functional group (FG) approach is used to predict the response of the composition of phytoplankton species to changes in the environmental conditions. We assessed for the first time the dynamics of phytoplankton communities in a High-Rate Algal Pond (HRAP), implemented for the bioremediation of landfill leachate, and using morphology-based functional groups (MBFG), under the American tropics conditions. These groups were later correlated with the physical and chemical variables of the system. Water samples were taken for biological, physical and chemical analysis for seven months. In addition, phytoplankton biovolumes were estimated and a canonical correlation analysis was performed to explain the relation between physical and chemical variables and FGs. Subsequently, the HRAP treated a medium-age leachate characterized by high concentrations of nutrients. Four MBFGs were identified (IV, V, VI and VII). Group V, conformed by phytoflagellates, was found to be dominant during the entire study period. This group proliferate in environments with high concentrations of organic matter, while contributing to the transformation of the contaminants present in the leachate. The largest biovolumes of Groups V and VII occurred during periods of low water levels and dissolved organic carbon.  Finally, we show that the MBFG technique may be useful in understanding the dynamics of the phytoplankton community in the HRAP used for the treatment of landfill leachate
