Synergic Effect of α

Cervical cancer is the second leading cause of death among Mexican women. The treatment with cis-diamminedichloroplatinum (II) (CDDP) has some serious side effects. Alpha-mangostin (α-M), has a protective effect against CDDP-induced nephrotoxicity, as well as antioxidant, antitumor, and anti-inflammatory properties. Hence, we explored the in vitro and in vivo effect of α-M on human cervical cancer cell proliferation when combined with CDDP. In vitro, The cytotoxic effect of α-M and/or CDDP was measured by the 3-(3,5-dimethylthiazol-2-yl)2,5-diphenyltetrazolium assay. Meanwhile, apoptosis, reactive oxygen species (ROS) production, and the cell cycle were determined with flow cytometry. For α-M+CDDP treatment, both a coincubation and preincubation scheme were employed. In vivo, xenotransplantation was performed in female athymic BALB/c (nu/nu) mice, and then tumor volume and body weight were measured weekly, whereas α-M interfered with the antiproliferative activity of CDDP in the coincubation scheme, with preincubation with α-M+CDDP showing significantly greater cytotoxicity than CDDP or α-M alone, significantly inhibiting average tumor volume and preventing nephrotoxicity. This effect was accompanied by increased apoptosis and ROS production by HeLa cervical cancer cells, as well as an arrest in the cell cycle. These results suggest that α-M may be useful as a neoadjuvant agent in cervical cancer therapy

Estimation of the real population and its impact on the utilisation of healthcare services in Mediterranean resort regions: an ecological study

BACKGROUND: The demographic structure has a significant influence on the use of healthcare services, as does the size of the population denominators. Very few studies have been published on methods for estimating the real population such as tourist resorts. The lack of information about these problems means there is a corresponding lack of information about the behaviour of populational denominators (the floating population or tourist load) and the effect of this on the use of healthcare services. The objectives of the study were: a) To determine the Municipal Solid Waste (MSW) ratio, per person per day, among populations of known size; b) to estimate, by means of this ratio, the real population in an area where tourist numbers are very significant; and c) to determine the impact on the utilisation of hospital emergency healthcare services of the registered population, in comparison to the non-resident population, in two areas where tourist numbers are very significant. METHODS: An ecological study design was employed. We analysed the Healthcare Districts of the Costa del Sol and the island of Menorca. Both are Spanish territories in the Mediterranean region. RESULTS: In the two areas analysed, the correlation coefficient between the MSW ratio and admissions to hospital emergency departments exceeded 0.9, with p < 0.001. On the basis of MSW generation ratios, obtained for a control zone and also measured in neighbouring countries, we estimated the real population. For the summer months, when tourist activity is greatest and demand for emergency healthcare at hospitals is highest, this value was found to be double that of the registered population. CONCLUSION: The MSW indicator, which is both ecological and indirect, can be used to estimate the real population in areas where population levels vary significantly during the year. This parameter is of interest in planning and dimensioning the provision of healthcare services

La degradación ambiental de los paisajes en las cuencas tributarias de la ensenada de Sibarimar (Guanabo e Itabo, Cuba)

The basins of the Guanabo and Itabo rivers are located in the northeaster limit of the La Habana province in Cuba. Meanwhile the urban and touristic uses of the territory are very significant in the coastline, the agriculture and the livestock are predominant in the hinterland. Just a few of natural areas remain in this area. Due to the conflict of uses and changing ecological features, the analysis of the environmental degradation of the landscapes is vital in order to establish a sustainable development of the territory. To reach this aim, we have classified the territory in units attending to the main ecological features that form the different landscapes. After that, we have carried out an integrated diagnosis taking into consideration aspects such as the main uses of the landscape units, its potential and efficiency, environmental dangers, degrading processes and geoecological state.Las cuencas de los ríos Guanabo e Itabo se localizan en el límite nororiental de la provincia de La Habana en Cuba. Mientras que los usos urbanos y turísticos son muy importantes en la costa, la agricultura y la ganadería son predominantes en el interior. Solamente quedan unas pocas áreas naturales. Debido al conflicto de usos y a las cambiantes características ecológicas es vital el análisis de la degradación medioambiental de los paisajes para establecer un desarrollo sostenible del territorio. Para alcanzar este objetivo hemos clasificado el territorio en unidades según las principales características que conforman los diferentes paisajes. Después de eso, hemos realizado un diagnóstico integrado teniendo en consideración aspectos como los principales usos de las unidades del paisaje, su potencial y eficiencia, los peligros ambientales, los procesos degradantes y el estado geoecológico.Les bassins hydrographiques des fleuves Itabo et Guanabo sont situés sur la limite nord de la province de La Havane, à Cuba. Alors que l'usages urbains et touristiques sont très importants sur la côte, de l'agriculture et l'élevage sont prédominant dans l'intérieur. Ils ne restent plus quelques zones naturelles résiduelles. En raison des conflits d'usages et de l'évolution des caractéristiques écologiques c'est très important faire d'analyse essentielle de la dégradation de l'environnement du paysage, pour établir un développement durable des terres. Pour ce faire, il faut divisé le territoire en unités suivant les caractéristiques qui ont les différents paysages. Après cela, on fera un diagnostic intégré en train de considérer des aspects tels que les prin- cipaux/dominant utilisations des unités de paysage, le potentiel et l'efficience, les risques et la dégradation sur l'environnement, et aussi l'état géoécologique
