Abstract: rural areas host many wild species and complement the conservation strategy of protected natural environments. we asked two questions in our investigation: a) which is the diversity of diurnal butterflies in the farm of the politécnico colombiano jic? b) what proportion has been referenced as forest indicator species in total sampled? the farm was divided into five zones and eleven samples were taken over the course of twelve months. the expected diversity was measured through non-parametric estimators and, the diversity was compared by zones with chi-square analysis. 933 were collected representing 117 families: nymphalidae (78), pieridae (18), hesperiidae (6), riodinidae (6), papilionidae (5), and lycaenidae (4). the most abundant nectariferous species were anartia amathea, anartia jatrophae and mechanitis menapsis. the only abundant fruit-feeding specie captured was pareuptychia hesione. 23% of the total species belong to subfamilies related to little disturbed ecosystems. the expected diversity was of 158 species and in our study we found 74% of this diversity. low species similarity was shown between zones. the highest diversity was found in zones one and two, which have great abundance of ornamental plants and wildflowers throughout the year. the presence of species typical from low disturbed areas could mean that forest patches are important by providing resources or as a migration route for these species on their way to forest patches.

Abstract: Los paisajes rurales albergan muchas especies silvestres y complementan la estrategia de conservación en las áreas naturales protegidas. Esta investigación se planteó dos preguntas: a) Cual es la diversidad de mariposas diurnas de la granja del Politécnico JIC?, b) De las especies encontradas qué proporción han sido referenciadas como indicadoras de bosques? Se dividió la granja en cinco zonas, en las cuales se realizaron once muestreos durante doce meses. Se determinó la diversidad esperada a través de estimadores no-paramétricos y se comparó la diversidad por zonas con el análisis de agrupamiento Chi-cuadrado. Se colectaron 933 individuos, que representaron 117 especies y seis familias: Nymphalidae (78), Pieridae (18), Hesperiidae (6), Riodinidae (6), Papilionidae (5) y Lycaenidae (4). Las especies nectarívoras más abundantes fueron Anartia amathea, Anartia jatrophae y Mechanitis menapsis, de las especies frugívoras capturadas, la única abundante fue Pareuptychia hesione. Un 23% de las especies pertenecen a subfamilias relacionadas con paisajes poco intervenidos. La diversidad esperada fue de 158 especies y este estudio encontró el 74% de ella. Las zonas presentaron baja similitud en las especies, la mayor diversidad y abundancia se presentó en las zonas uno y dos, posiblemente debido a la mayor abundancia de plantas ornamentales y arvenses florecidas todo el a o. La presencia de especies típicas de sitios poco intervenidos indicaría que los parches de bosque de la granja son importantes en la provisión de recursos para las mariposas o como ruta de paso hacia parches de bosque mayores en este paisaje.

Abstract: objectives: to evaluate the efficacy of ranibizumab in wet age-related macular degeneration (armd), and to identify prognostic factors. methods: a retrospective longitudinal study of 79 eyes treated with intravitreal ranibizumab in our hospital due to wet armd, with an initial regimen of three consecutive monthly injections, followed by injections on demand based on the exploratory findings. we conducted a descriptive study of the baseline examination (n=79), and 3 (n=79), 6 (n=67) and 12 months (n=49) after starting treatment. the characteristics of the baseline examination and annual examination results were compared using univariate and multivariate analysis. results: after the three initial injections, the 93.67% of patients lost fewer than 15 letters, and 19% gained 15 points or more. this result remained similar at 1 year (83.67% and 20.40%, respectively). after 1 year of treatment 40.82% had a va > 0.3 and 22′45% had a va < 0.1. we used a median of 5 injections per year. the increased av at the beginning and the persistence of large intraretinal cysts at 3 months (p=.0013), as well as the development of fibrosis during evolution (p=.0005), are associated with visual deterioration. conclusions: the guidelines used here stabilised or improved visual acuity in most patients. the most favourable cases are those with initially lower va or large intraretinal cysts resolved after the loading phase. the appearance of fibrosis implies a poor long-term visual prognosis.

Abstract: En el trópico se dispone de pocos datos de la mayoría de los organismos, incluyendo las mariposas, en aspectos claves de su ciclo de vida, sus plantas hospederas y factores explicativos de su diversidad y abundancia. El objetivo de este trabajo fue identificar las plantas hospederas de larvas Ithomiini (Lepidoptera) en agroecosistemas de café y evaluar el efecto de las variables: sistema de producción, área en bosque y diversidad de hospederas sobre la diversidad y abundancia de este grupo. En seis fincas de café de Fredonia (Antioquia), Colombia, se recolectaron plantas de las familias Apocynaceae, Gesneriaceae y Solanaceae, que fueron identificadas en los Herbarios HUA y MEDEL de Medellín. En las fincas se registraron los adultos observados en vuelo y se recolectaron huevos, larvas y pupas de Ithomiini de sus plantas hospederas para su cría en laboratorio, hasta la emergencia de adultos. Se determinó el porcentaje de sobrevivencia y mortalidad debida a parasitoidismo. Los datos de diversidad se analizaron por medio de un Análisis de Regresión de Poisson. En los agroecosistemas de café se registraron 27 especies vegetales y 27 mariposas adultas Ithomiini, en laboratorio, se criaron 326 individuos de ocho especies, recolectados sobre siete plantas de la familia Solanaceae. Dos plantas constituyen registros nuevos como hospederas de las especies de Lepidoptera: Solanum atropurpureum hospedera de Mechanitis menapis y Solanum deflexiflorum hospedera de Pteronymia picta y P. latilla. La diversidad de Ithomiini fue explicada por la diversidad de hospederas y por el sistema de sombrío.

Abstract: Objetivos: Evaluar la eficacia del tratamiento con ranibizumab en la degeneración macular asociada a la edad (DMAE) exudativa e identificar los factores pronósticos. Método: Estudio longitudinal retrospectivo de 79 ojos, tratados con ranibizumab intravítreo en nuestro centro por DMAE exudativa, con una pauta inicial de 3 inyecciones consecutivas mensuales, seguidas de inyecciones a demanda en función de los hallazgos exploratorios. Se realizó un estudio descriptivo de la exploración basal (n=79), y a los 3 (n=79), 6 (n=67) y 12 meses (n=49) del inicio del tratamiento. Mediante análisis univariante y multivariante se correlacionaron las características de la exploración basal y anual con los resultados visuales. Resultados: Después de las 3 inyecciones iniciales, el 93,67% de los casos pierde menos de 15 letras, y un 19% gana 15 letras o más. Este resultado es similar al a o (83,67 y 20,40%, respectivamente). Tras un a o de tratamiento mantiene una agudeza visual (AV) > 0,3 el 40,82%, y un 22,45% tiene una AV < 0,1. Se ha utilizado una mediana de 5 inyecciones/a o. La AV elevada al inicio y la persistencia de quistes intrarretinianos grandes a los 3 meses (p=0,0013), así como la aparición de fibrosis durante la evolución (p=0,0005) se asocian con un empeoramiento visual. Conclusiones: La pauta utilizada permite una estabilización o mejoría de la AV en la mayor parte de los pacientes. Los casos más favorables inicialmente son aquellos que presentan una AV más baja o quistes intrarretinianos grandes resueltos tras la fase de carga. La aparición de fibrosis implica un mal pronóstico visual a largo plazo.

Abstract: Background A 21-gene recurrence score (RS) assay may inform adjuvant systematic treatment decisions in women with early stage breast cancer. We sought to investigate the cost effectiveness of using the RS-assay versus current clinical practice (CCP) in women with early-stage estrogen- or progesterone-receptor-positive, axilliary lymph-node negative breast cancer (ER+/ PR + LN- ESBC) from the perspective of the Canadian public healthcare system. Methods We developed a Markov model to project the lifetime clinical and economic consequences of ESBC. We evaluated adjuvant therapy separately in post- and pre-menopausal women with ER+/ PR + LN- ESBC. We assumed that the RS-assay would reclassify pre- and post-menopausal women among risk levels (low, intermediate and high) and guide adjuvant systematic treatment decisions. The model was parameterized using 7 year follow up data from the Manitoba Cancer Registry, cost data from Manitoba administrative databases, and secondary sources. Costs are presented in 2010 CAD. Future costs and benefits were discounted at 5%. Results The RS-assay compared to CCP generated cost-savings in pre-menopausal women and had an ICER of $60,000 per QALY gained in post-menopausal women. The cost effectiveness was most sensitive to the proportion of women classified as intermediate risk by the RS-assay who receive adjuvant chemotherapy and the risk of relapse in the RS-assay model. Conclusions The RS-assay is likely to be cost effective in the Canadian healthcare system and should be considered for adoption in women with ER+/ PR + LN- ESBC. However, ongoing assessment and validation of the assay in real-world clinical practice is warranted.

Abstract: A Regi o Histórica das Miss es Jesuítica-Guaranis possui um patrim nio diversificado. Atualmente esses bens culturais, est o sendo melhor planejados por órg os nacionais e internacionais. No entanto, percebe-se a falta de estudos voltados para a análise da constru o da identidade missioneira e suas rela es com as transforma es do espa o. O artigo centrou-se em analisar a constru o identitária missioneira a partir da interpreta o das paisagens regionais, visando refletir sobre a constitui o dos espa os sociais. Para tanto, foi utilizado como matriz teórica às reflex es do pensador francês Guy Di Méo. O estudo destaca-se por propor a discuss o de uma vis o n o unificada para a identidade missioneira, pois a pesquisa consegue identificar diversas identidades sócio-espaciais na regi o. Cabe salientar que os pensamentos de Guy di Méo contribuíram para a integra o de conceitos entre, identidade, patrim nio, espa os sociais, paisagens, e turismo. O que prop e uma vis o inovadora para a Geografia Cultural das Miss es. The micro-identities of Region Jesuiti Guarani Missions through interpretation of cultural landscapes: a dialectic with the reflections of Guy Di Méo Abstract: The Historic Region of Jesuit Guarani Missions has a diverse heritage. Currently these cultural assets are being planned by best international and national bodies. However, one notices the lack of studies to analyze the construction of the missionary identity and its relations with the transformations of space. The article focused on analyzing missionary identity construction from the interpretation of regional landscapes, to reflect on the creation of social spaces. There fore, it was used as a theoretical framework to the reflections of the French philosopher Guy Di Meo. The study stands out for proposing the discussion of a unified vision for the identity not missions,because the research can identify various socio-spatial identitie sin the region. It should be noted that the thoughts of Guy Di Meo contributed to the integration of concepts between, identity, heritage, social spaces, landscapes, and tourism. What proposes an innovative vision for the Cultural Geography of the Missions. DOI: 10.7154/RDG.2012.0024.0008
DINAMISMO ILEGAL Y DESAFíO OFICIAL: EL CONTRABANDO EN TUMACO Y EL PACíFICO SUR EN LAS DéCADAS DE 1860 Y 1870

Abstract: this article discusses the problems of contraband in tumaco and the surrounding region in the 1860s and 1870s, at the beginning of the export bonanza through this port. using contraband as way to identify merchants, commercial routes, and imported products, it is possible to analyze the commercial dynamic of tumaco before the port had acquired its later importance in the national economy. we suggest that tumaco already experienced a particular dynamism based on illicit trade that was crucial for the region even though it threatened state authority and its finances.
