| ABSTRACT Fruits of Gevuina avellana (Proteaceae) seem to mimic wasp-induced galls of Nothofagus dombeyi (Nothofagaceae) to escape predation by rodents, which may change both spatially and temporarily. The objective of this study was to evaluate the similarity between the fruits of G. avellana and the galls of N. dombeyi and to determine if this similarity protects fruits from predation by rodents in a disturbed temperate forest. We evaluated: i) the similarity between fruits and galls by measuring length, diameter, weight and color; and ii) the effects of galls on fruit predation by offering them to rodents in varying proportions, in a forest and a meadow, over two years. Fruits and galls showed similar phenotypes but fruits were more consumed than galls,... |

| Combarbalá-INIA es un nuevo cultivar de hualputra (Medicago polymorpha L.), seleccionado entre un gran número de accesiones colectadas en Chile, entre La Serena (29º 55 lat. Sur) y Temuco (38º 47 lat. Sur). Es una leguminosa forrajera anual, precoz (71 - 83 días desde emergencia a primera flor), apta para áreas de secano de la zona mediterránea árida, semiárida y subhúmeda, es decir, entre la IV y VI Regiones de Chile. Presenta un hábito de crecimiento postrado, flores de color amarillo, y los gloquídeos no tienen espinas. Se adapta muy bien a sistemas de rotación con cereales ("ley farming system"), ya que produce una gran cantidad de semillas duras impermeables al agua. La producción de fitomasa y de semillas es superior a la de cultivares australianos... |

| En Chile la producción de cebada (Hordeum vulgare L.), se destina principalmente a la fabricación de malta y cerveza. En 1978, el Instituto de Investigaciones Agropecuarias (INIA) y la Compañía Cervecerías Unidas (CCU), la más importante empresa productora de cerveza del país, firmaron un convenio de investigación con el propósito de iniciar trabajos de mejoramiento genético para producir variedades de cebada con altos rendimientos y elevada calidad maltera. Las nuevas variedades creadas a través de este convenio han sido entregadas por CCU a los productores bajo un sistema de contrato de producción. Desde 1978 hasta 1999, INIA introdujo la variedad Aramir y creó las variedades Granifén INIA/CCU, Libra INIA/CCU y Acuario INIA/CCU, que han sido cultivadas... |

| Cauquenes INIA es el primer cultivar de hualputra (Medicago polymorpha L.), liberada por el Centro Experimental Cauquenes del Instituto de Investigaciones Agropecuarias (INIA). Fue seleccionado desde una colección de germoplasma que obtenida en una expedición a través de la zona Mediterránea de Chile, entre La Serena (29º 55 lat. S) y Temuco (38º 47 lat. S), en 1988. Es una leguminosa forrajera anual, para zonas de secano mediterráneo subhúmedo y húmedo, especialmente apropiada para sistemas agrícolas donde la pradera va en rotación con cereales ("ley farming systems"). Es un cultivar semiprecoz, de hábito de crecimiento semi-erecto, flores de color amarillo, gloquídeos sin espinas, y alto porcentaje de semillas duras. La producción de materia seca (6570... |

| El objetivo del presente trabajo fue analizar la expresión transcripcional inducida bajo diferentes tipos de estrés biótico y abiótico en plantas de chile habanero (Capsicum chinense BG-3821). Los estudios de expresión de genes de plantas bajo diferentes condiciones de estrés biótico y abiótico son importantes porgue son una estrategia para entender, a nivel molecular, cómo las plantas actúan en fenómenos de resistencia a patógenos y condiciones abióticas de crecimiento, lo que puede ampliar el conocimiento sobre los mecanismos moleculares de defensa a estos tipos de estrés en las plantas. Para el análisis transeripcional se emplearon sondas moleculares de los EST R50 y R100. Ambos son fragmentos diferenciales y posiblemente implicados en la respuesta de... |

| The low diversity of the Austral Basin ammonoid faunas was traditionally associated with a high degree of endemism. However, as reported herein, the ammonoids belonging to the Family Ancyloceratidae, Subfamily Crioceratitinae have affinities with European forms. Therefore, the Hauterivian ammonoids of the Austral Basin represent a mixture of endemic (Favrella Douvillé), with typical Tethyan examples (Hemihoplites Spath, Crioceratites Léveillé), and faunas that are characteristic of Northwestern Europe on the margins of the Boreal realm (Protaconeceras Casey, Aegocrioceras Spath), although the endemic forms dominate in number of specimens. The following species are described here: Aegocrioceras patagonicum sp. nov. Aguirre-Urreta, Crioceratites (C.) apricum... |

| Descreve-se o primeiro caso de paratuberculose em veado pudu-do-sul (Pudu pudu). O animal foi encontrado na cidade de Concepción, centro sul do Chile, em péssimas condições e com sinais claros de diarréia. Internamente apresentava séria atrofia de gordura no coração, lesões histológicas nos pulmões, fígado, baço e rins, e injúrias intestinais. Diferentes amostras foram preparadas com Ziehl-Neelsen, e os linfonodos mesentéricos presentes no íleo foram fortemente positivos para a bactéria resistente ao ácido. |

| INTRODUCTION: The South American country Chile now boasts a life expectancy of over 80 years. As a consequence, Chile now faces the increasing social and economic burden of cancer and must implement political policy to deliver equitable cancer care. Hindering the development of a national cancer policy is the lack of comprehensive analysis of cancer infrastructure and economic impact. OBJECTIVES: Evaluate existing cancer policy, the extent of national investigation and the socio-economic impact of cancer to deliver guidelines for the framing of an equitable national cancer policy. METHODS: Burden, research and care-policy systems were assessed by triangulating objective system metrics -epidemiological, economic, etc. - with political and policy analysis.... |

| Diarrhetic shellfish poisoning (DSP) is a gastrointestinal disease caused by lipid soluble polyether toxins produced by dinoflagellates and accumulated in shellfish. Diarrhetic shellfish poisoning is a worldwide threat to public health and the shellfish industry. To date, only four lipid soluble polyethers have been known as diarrhetic shellfish toxins. Among them, Okadaic acid (OA), Dinophysistoxin 1 (DTX-1, 35-methyl OA), Dinophysistoxin 2 (DTX-2, OA isomers) and Dinophysistoxin 3 (DTX-3, 7-O-acyl-35-methyl OA), all of which have free carboxilic groups. To perform quantitative analysis of DSP toxins in shellfish samples is a requirement, because DSP toxins are endemic in the Chilean mollusks of the southern regions, and although human symptoms of DSP... |

| During the last decade the articles published by Chilean Research Centers grew 1,73 which compares to the 2.34 fold increase of mainstream research articles registered as a whole in Latin America. However, the relative impact of the Chilean publications surpassed that of Latin America. In Biological Sciences, traditionally the strongest research area within Chile, Latin America also shows a steeper slope of growth. Qualitatively, biological disciplines in Chile are comparable to those published in Latin America although in Chile there are specialties as Physiology that surpass the average world's impact. The scientometric data is consistent with the fall in individual grants that the Chilean Research Fund (FONDECYT) has been allocating during the last... |

| BACKGROUND: The body site location of primary Malignant Melanoma (MM) has been correlated with prognosis and survival. Ethnic, genetics, sun exposure factors are related to the anatomical distribution of MM. Low and high socioeconomic strata in Chile differ in ethnic, genetic and cultural conditions. The purpose of this study was to analyze the anatomical MM distribution in the Chilean population in both strata searching for differences due to their ethno-genetic-cultural differences. Records of 1148 MM, 575cases from state hospitals (Low Socioeconomic Strata, LSS) and 573 cases from private clinics (High Socioeconomic Strata, HSS) were analyzed by body site. RESULTS: Females from LSS showed a higher number of MM in soles, cheeks, and around the eye area.... |
