    The threat of disease transmission from domestic animals to wildlife has become recognized as an increasing concern within the wildlife community in recent years. Domestic dogs pose a significant risk as reservoirs for infectious diseases, especially for wild canids. As part of a multifaceted ecologic study of maned wolves and other canids in the large, remote Noël Kempff Mercado National Park (NKMNP) in northeastern Bolivia, 40 domestic dogs in two villages and at two smaller settlements bordering the national park were sampled for exposure to canine diseases. High levels of exposure were found to canine distemper virus and canine parvovirus, both of which are known to cause mortality in maned wolves and other carnivores. Moderate to high levels of exposure were found to rabies virus, Ehrlichia canis, and Toxoplasma gondii, as well as significant levels of infection with Dirofilaria immitis. This study reports evidence of exposure to several diseases in the domestic dogs bordering the park. Contact between wild carnivores and dogs has been documented in the sampled villages, therefore dogs likely pose a substantial risk to the carnivores within and near NKMNP. Further measures should be undertaken to decrease the risk of spillover infection from domestic animals into the wild species of this region.

    Urban food swamps are typically situated in low-income, minority communities and contribute to overweight and obesity. Changing the food landscape in low income and underserved communities is one strategy to combat the negative health consequences associated with the lack of access to healthy food resources and an abundance of unhealthy food venues. In this paper, we describe Proyecto MercadoFRESCO (Fresh Market Project), a corner store intervention project in East Los Angeles and Boyle Heights in California that used a multi-level approach with a broad range of community, business, and academic partners. These are two neighboring, predominantly Latino communities that have high rates of overweight and obesity. Located in these two communities are approximately 150 corner stores. The project used a community-engaged approach to select, recruit, and convert four corner stores, so that they could become healthy community assets in order to improve residents’ access to and awareness of fresh and affordable fruits and vegetables in their immediate neighborhoods. We describe the study framework for the multi-level intervention, which includes having multiple stakeholders, expertise in corner store operations, community and youth engagement strategies, and social marketing campaigns. We also describe the evaluation and survey methodology to determine community and patron impact of the intervention. This paper provides a framework useful to a variety of public health stakeholders for implementing a community-engaged corner store conversion, particularly in an urban food swamp. PMID:25209600

  6. Exposure of free-ranging maned wolves (Chrysocyon brachyurus) to infectious and parasitic disease agents in the Noël Kempff Mercado National Park, Bolivia.

    2005-06-01

    Maned wolves (Chrysocyon brachyurus) are neotropic mammals, listed as a CITES Appendix II species, with a distribution south of the Amazon forest from Bolivia, through northern Argentina and Paraguay and into eastern Brazil and northern Uruguay. Primary threats to the survival of free-ranging maned wolves include habitat loss, road kills, and shooting by farmers. An additional threat to the conservation of maned wolves is the risk of morbidity and mortality due to infectious and parasitic diseases. Captive maned wolves are susceptible to, and die from, common infectious diseases of domestic dogs (Canis familiaris) including canine distemper virus (CDV), canine parvovirus (CPV), rabies virus, and canine adenovirus (CAV). Results from this study show that free-ranging maned wolves in a remote area of Bolivia have been exposed to multiple infectious and parasitic agents of domestic carnivores, including CAV, CDV, CPV, canine coronavirus, rabies virus, Leptospira interrogans spp., Toxoplasma gondii, and Dirofilaria immitis, and may be at increased risk for disease due to these agents.

  7. The metal alloys from the XIX century and weathering action in the Mercado do Ver-o-Peso building, northern Brazil: Identification with the usage of laboratory analysis

    The fabrication of metallic buildings started in Europe after the Industrial Revolution in the 18th century. Metallic constructions became very popular, and started being imported by several countries, due to the facility of constructing or assembling. Belém, a northern Brazilian city, holds a great number of buildings entirely made of iron, including the Ver-o-Peso, a fish market which structures were imported from England by the end of the 19th century. This building represents a unique type of architecture and it's an important part of the city's heritage. However, research so far did not focus on its construction materials. Ver-o-Peso building's metal alloys haven't been thoroughly studied concerning physical, chemical and mineralogical characterizations. This paper aims to identify the types of metal alloys used in the building, and also corrosion products' result from weathering actions. The methods used to characterize the materials were scanning electron microscopy and X-ray diffraction. Through this research it was possible to identify four types of iron alloys used in the different parts of the building, characterize the paint coats, and determine types of corrosion. The characterization of the materials in the building allows enrolling basis for restoration processes, documenting the types of metal alloy used in architectural heritage from the 19th century, as well as understanding the advances of corrosion. - Highlights: • Ver-o-peso is a heritage building from the 19th century with unidentified alloys. • Alloy and weathering product characterization was done using SEM/EDS and XRD. • Four metal alloy types were described, indicating different types of foundries. • Weathering products showed distinct mineral phases and physical characteristics. • Original paint coats were found among corrosion products.

  9. The effects of past climate variability on fire and vegetation in the cerrãdo savanna ecosystem of the Huanchaca Mesetta, Noel Kempff Mercado National Park, NE Bolivia

    Cerrãdo savannas have the greatest fire activity of all major global land-cover types and play a significant role in the global carbon cycle. During the 21st century, temperatures are predicted to increase by ~ 3 °C coupled with a precipitation decrease of ~ 20%. Although these conditions could potentially intensify drought stress, it is unknown how that might alter vegetation composition and fire regimes. To assess how Neotropical savannas responded to past climate changes, a 14 500 year, high-resolution, sedimentary record from Huanchaca Mesetta, a palm swamp located in the cerrãdo savanna in northeastern Bolivia, was analyzed for phytoliths, stable isotopes and charcoal. A non-analogue, cold-adapted vegetation community dominated the Late Glacial-Early Holocene period (14 500-9000 ka), that included trees and C3 Pooideae and C4 Panicoideae grasses. The Late Glacial vegetation was fire sensitive and fire activity during this period was low, likely responding to fuel availability and limitation. Although similar vegetation characterized the Early Holocene, the warming conditions associated with the onset of the Holocene led to an initial increase in fire activity. Huanchaca Mesetta became increasingly fire-dependent during the Middle Holocene with the expansion of C4 fire adapted grasses. However, as warm, dry conditions, characterized by increased length and severity of the dry season, continued, fuel availability decreased. The establishment of the modern palm swamp vegetation occurred at 5000 cal yr BP. Edaphic factors are the first order control on vegetation on the rocky quartzite mesetta. Where soils are sufficiently thick, climate is the second order control of vegetation on the mesetta. The presence of the modern palm swamp is attributed to two factors: (1) increased precipitation that increased water table levels, and (2) decreased frequency and duration of surazos leading to increased temperature minima. Natural (soil, climate, fire) drivers rather than anthropogenic drivers control the vegetation and fire activity at Huanchaca Mesetta. Thus the cerrãdo savanna ecosystem of the Huanchaca Plateau has exhibited ecosystem resilience to major climatic changes in both temperature and precipitation since the Late Glacial period.

  10. La inserción en el mercado laboral de los inmigrantes latinos en España y en los Estados Unidos: Diferencias por país de origen y estatus legal

    Resumen Este artículo compara los resultados económicos entre los inmigrantes latinoamericanos en España y Estados Unidos. Detectamos un efecto de selección por el que la mayoría de los inmigrantes latinoamericanos en España proceden de Sudamérica de un entorno de clases medias, mientras la mayoría de los inmigrantes que van a los Estados Unidos son centroamericanos de clase baja. Este efecto de selección explica las diferencias transnacionales en la probabilidad de empleo, logro ocupacional y salarios obtenidos. A pesar de las diferencias en los orígenes y las características de los latinoamericanos en ambos países, los factores demográficos, humanos y de capital social parecen operar de forma similar en ambos países; y cuando los modelos se estiman separadamente por estatus legal, descubrimos que los efectos se acentúan más entre los inmigrantes irregulares cuando se los compara con los regulares, especialmente en Estados Unidos.

    The Puerto Rico Trench, the deepest part of the Atlantic Ocean, is located where the North American (NOAM) plate is subducting under the Caribbean plate (Figure l). The trench region may pose significant seismic and tsunami hazards to Puerto Rico and the U.S.Virgin Islands, where 4 million U.S. citizens reside. Widespread damage in Puerto Rico and Hispaniola from an earthquake in 1787 was estimated to be the result of a magnitude 8 earthquake north of the islands [McCann et al., 2004]. A tsunami killed 40 people in NW Puerto Rico following a magnitude 7.3 earthquake in 1918 [Mercado and McCann, 1998]. Large landslide escarpments have been mapped on the seafloor north of Puerto Rico [Mercado et al., 2002; Schwab et al., 1991],although their ages are unknown.

Se registró información nutricional de 9 categorías de productos representativos en la cesta de la compra de las familias españolas. Las declaraciones nutricionales analizadas hacen mención de los nutrientes que pueden contribuir o no al exceso de peso.Resultados: se examinó un total de 4.568 productos y se encontraron un total de 900 declaraciones nutricionales en el 20% de los productos analizados. Los nutrientes referidos en las declaraciones nutricionales encontrados con mayor frecuencia en las 9 categorías de productos fueron las grasas (42%), los azúcares (32%), la fibra alimentaria (20%) y la sal (6%). Conclusiones: al igual que en otros estudios realizados en España, nuestro estudio mostró una baja proporción de declaraciones nutricionales. Por lo tanto, para que estas cumplan su función informativa tanto la industria como la distribución alimentaria deben seguir trabajando por incluir más declaraciones en los alimentos que ofrecen. De esta manera facilitarán a los consumidores una mejor toma de decisiones alimentarias.

    2008-06-01

    The Ohmeda Universal Portable Anesthesia Complete (U-PAC) draw-over anesthetic system is active in the US Army inventory. It is standard equipment for Certified Registered Nurse Anesthetists assigned to US Army Forward Surgical Teams and Joint Special Operations Command. The purpose of this article is to describe a practical and field-expedient U-PAC draw-over vaporizer setup used during Operation Iraqi Freedom I (February 2003 to July 2003). During the deployment, general anesthesia was administered to 25 patients with penetrating trauma using the Gegel-Mercado setup without system malfunction. This setup strengthens the standard U-PAC draw-over system delivery because it increases fractional inspired oxygen concentrations, promotes hands-free operation, enhances circuit cleanliness reducing cross contamination, and provides an alternate method for draw-over anesthesia administration in austere conditions when a ventilator may not be available or practical. It integrates and builds on the core concepts of draw-over anesthesia delivery in the literature. The Gegel-Mercado setup is combat proven.

    Resumen Objetivos: obtener estimaciones de indicadores de cobertura de las pensiones por jubilación o retiro para la población mexicana de 65 y más años, y evaluar el impacto que tienen los sistemas de pensiones en las transiciones al retiro de los adultos en edades medias y avanzadas en México. Para ello se utilizan datos microeconómicos provenientes de la Encuesta Nacional de Salud y Envejecimiento. Mediante análisis econométrico se identifican los factores sociodemográficos, económicos, laborales e institucionales que están asociados al acceso a una pensión de jubilación, o bien, a la dependencia de otras fuentes de ingresos. Se encontró que, en México, las transiciones al retiro del mercado de trabajo en las etapas avanzadas del ciclo de vida son limitadas debido a las características eminentemente contributivas de los esquemas de pensiones, los cuales favorecen a la población con trayectorias laborales formales y más estables asociadas a: características de género, oportunidades educativas y posibilidades de inserción en el mercado laboral.

  1. Effect of heat treatment and milling on the seed, flour, rheology and baking quality of some amaranth ecotypes.

    PubMed

    Sánchez-Marroquín, A; Maya, S; Domingo, M V

    1985-12-01

    Forty-five harvests corresponding to the two predominating domestic species of amaranth in Mexico were studied. The proximate analysis revealed some statistically significant differences throughout three years of observation. The Ca, P and Fe content did not vary greatly in 15 samples. No chemical differences were either manifested in the Mercado and Aztec types of A. hypochondriacus, nor in the Mexican type of A. cruentus. The latter exhibits a higher grain yield and a shorter life cycle; however, its baking quality is apparently inferior to that of the Mercado type of A. hypochondriacus. The heat treatment of the seeds (toasting, popping and cooking) affected protein and lysine contents as does in cereals and leguminous seeds although toasting in particular improves its sensory characteristics without altering digestibility and PER. Popping only improves PER. Heating at 90 or 170 degrees C for three to five minutes, at the usual seed's moisture rate of 6 to 15%, does not affect protein content and does so only slightly in the case of the fatty acids content. Amylographic and farinographic values of the starchy fractions indicate similarities to C. quinoa and differences with respect to wheat. In the case of "amaranth milk", viscosity and gelatinization temperature produced satisfactory values. The extension of amaranth cultivation in the country is hereby suggested in view of the seed's nutritional quality, and considering the behavior of whole amaranth flour and its fractions.

  2. Peril in the market-classification and dosage of species used as anti-diabetics in Lima, Peru

    PubMed Central

    2013-01-01

    Background Peru is what Peruvian anthropologist Lupe Camino calls the “health axis” of the old Central Andean culture area stretching from Ecuador to Bolivia. In particular in the North of the country the traditional use of medicinal dates back as far as the first millennium B.C. Both healers, and the wider population, often buy their medicinal plants in local markets, but there is very little comparative information available about which plants are sold under which vernacular name at any given time, for which indication, and which dosage information and information about side effects is given by vendors. For this study we used two traditionally used species groups “Hercampuri” Gentianella spec. (Gentianaceae) and “Pasuchaca” Geranium spec. (Geraniaceae.), found in the Mercado Aviación in Lima, as small, clearly circumscribed plant group frequently used to treat symptoms of diabetes as a test case to study the taxonomy, indications, dosage, indicated side effects, and additional species used as admixtures and hypothesized that: 1. A wide variety of different species is sold under the same common name, and often several common names exist for one species. 2. There is no consistency in the dosage, or a relationship between dosage and species marketed under one name. 3. However, there is consistency in the knowledge about usage and side effects. Methods Surveys focusing on medicinal plants sold and their properties were conducted at the Mercado Aviación in Lima in December 2012. Vouchers of all specimens were deposited at the National Herbarium of Peru. Results and conclusions Our surveys in Mercado Aviación in Lima yielded four species of Gentianella, two of Geranium, and three additional species from three genera used as common additives that were sold as anti-diabetic. These results indicate that even in case of only a few plant species, used for a very clearly circumscribed application, patients run a considerable risk when purchasing their remedies

    This article examines the effectiveness of the environmental management approach used by Argentina and Bolivia as a means to a better life for the many impoverished people who live in this area. The approach aims to integrate environmental and development concerns in a plan for the future of the region. With financial support from international agencies, Argentina and Bolivia are conducting a wide-ranging study of a border-spanning watershed that spreads over 190,000 sq. km. The two countries want to learn how to make better decisions about development. These decisions are aimed to preserve the environment and improve economic opportunity for the 1.2 million people of the region. The study conducted will explore ecotourism as a strategy for forest preservation and increased economic opportunity. The two countries have been working together with the Organizations of American States for nearly 20 years. This collaboration is an attempt to improve the condition of the watershed. Efforts to find answers in the Bermejo River basin are motivated by an integrated form of environmental science, the economic hardships of the people of the region, and a new economic dynamism inspired by Mercosur, the Mercado Comun del Sur or Common Market of the South. The Mercosur agreement also places a special emphasis on social justice, efficient use of available resources, and preservation of the environment. The reliable and well-managed water resources are critical to industrialization, and the improvement in the way of life of the people in the Bermejo watershed region.

  8. The Impact of Radiation Changes on the Terrestrial Carbon Sink over the Post Pinatubo Period

    The amount of solar radiation reaching the earth surface is one of the major drivers of plant photosynthesis and therefore changes in radiation are likely to indirectly have an effect on the terrestrial carbon cycle. For example, changes in surface radiation that lead to increasing diffuse surface irradiance are reported to enhance plant photosynthesis (Gu et al., 2003, Niyogi et al., 2004, Oliveira et al., 2007, Roderick et al., 2001). Solar radiation reaching the land surface has changed over the industrial era due to aerosols emitted from volcanoes and various anthropogenic sources (Kvalevag and Myhre, 2007). Such changes in total surface radiation are accompanied by changes in direct and diffuse surface solar radiation. Recent major volcanic events include the eruptions of el Chichón in 1986 and Mount Pinatubo in 1991. In this study we estimate the impact of changes in surface radiation on photosynthetic carbon uptake during the Post Pinatubo period. We use an offline version of the Hadley Centre land surface scheme (Mercado et al., 2007) modified to account for variations in direct and diffuse radiation on sunlit and shaded canopy photosynthesis. We use meteorological forcing from the Climate Research Unit Data set. Additionally short wave and photosynthetic active radiation are reconstructed from the Hadley centre climate model, which accounts for the scattering and absorption of light by tropospheric and stratospheric aerosols. We describe the development of the land carbon cycle through the Pinatubo event and diagnose the impact of changes in diffuse radiation on the atmospheric [CO2] growth-rate

    Surveys for Stenoma catenifer Walsingham, the avocado seed moth, and its associated larval parasitoids were conducted in the Departments of Junín, Huánuco, Cusco, and Madre de Dios in Perú. Fruit infestation levels in some areas ranged from 0 to 58%, and parasitism of S. catenifer larvae in Junín and Huánuco was 23%. Five species of hymenopteran parasitoid in two families, Braconidae (Apanteles sp., Hypomicrogaster sp., and Chelonus sp.) and Ichneumonidae (Pristeromerus sp. and Xiphosomella sp.), were reared from larvae, and one species of tachinid fly (Chrysodoria sp.) emerged from pupae. The dominant larval parasitoid, a gregarious Apanteles sp., accounted for 55% of parasitized hosts. Branch and twig tunneling by S. catenifer larvae in a commercial Hass avocado orchard was observed in Cusco. The field attractiveness of the sex pheromone of S. catenifer was demonstrated with 73% of monitoring traps deployed in three departments (Junín, Huánuco, and Cusco) catching male moths. Approximately 55% of avocado fruit sourced from the Province of Chanchamayo (Junin) and purchased at the Mercado Modelo de Frutas in La Victoria, in central Lima were infested with larvae of S. catenifer. Infested avocado fruit sold at this market could represent a potential incursion threat to coastal Hass avocado production regions in Perú that are reportedly free of this pest.

    The Brazilian pharmaceutical industry is heavily dependent on external sources of inputs, capital, and technology. However, the emergence of technological opportunities and the development of biotechnology and the decline of the patent boom and resulting advances by generic drugs have opened windows of opportunities for the local industry. The article examines the Brazilian industry's innovative behavior vis-à-vis these opportunities, showing that although the industry as a whole invests little in innovation, a few large Brazilian companies have expanded their market share and stepped up their investments in research and development, supported by public policies for innovation. Resumo: A indústria farmacêutica brasileira caracteriza-se pela grande dependência de fontes externas de insumos, capital e tecnologia. O surgimento de oportunidades tecnológicas, associadas ao desenvolvimento da biotecnologia e ao fim do boom das patentes com o consequente avanço dos medicamentos genéricos, entretanto, vem abrindo janelas de oportunidades para a indústria local. Este artigo examina o comportamento inovador da indústria brasileira à luz dessas oportunidades, revelando que, embora o conjunto da indústria mantenha baixos níveis de investimentos em inovação, um pequeno grupo de grandes empresas nacionais vem ampliando sua participação no mercado e intensificando seus investimentos em pesquisa e desenvolvimento, apoiados por políticas públicas de inovação.

  12. Cross-language influences: translation status affects intraword sense relatedness.

    Many words have more than one meaning, and these meanings vary in their degree of relatedness. In the present experiment, we examined whether this degree of relatedness is influenced by whether or not the two meanings share a translation in a bilingual's other language. Native English speakers with Spanish as a second language (i.e., English-Spanish bilinguals) and native Spanish speakers with English as a second language (i.e., Spanish-English bilinguals) were presented with pairs of phrases instantiating different senses of ambiguous English words (e.g., dinner date-expiration date) and were asked to decide whether the two senses were related in meaning. Critically, for some pairs of phrases, a single Spanish translation encompassed both meanings of the ambiguous word (joint-translation condition; e.g., mercado in Spanish refers to both a flea market and the housing market), but for others, each sense corresponded to a different Spanish translation (split-translation condition; e.g., cita in Spanish refers to a dinner date, but fecha refers to an expiration date). The proportions of "yes" (related) responses revealed that, relative to monolingual English speakers, Spanish-English bilinguals consider joint-translation senses to be less related than split-translation senses. These findings exemplify semantic cross-language influences from a first to a second language and reveal the semantic structure of the bilingual lexicon.

    The rare-earth element (REE) distribution in natural apatite is analysed by micro-PIXE, cathodoluminescence (CL) microscopy and spectroscopy and electron spin resonance (ESR) spectroscopy. The micro-PIXE analyses of an apatite crystal from Cerro de Mercado (Mexico) and the summary of 20 analyses of six francolite (conodonts of Triassic age) samples indicate that most of the REEs are enriched in apatite and francolite comparative to average shale standard (NASC). The analyses of fossil francolite revealing the REE-distribution not to be in balance with the REE-distribution of seawater and fish bone debris. Strong inhomogenous lateral REE-distribution in fossil conodont material is shown by CL-mapping and most probably not being a vital effect. Therefore, the resulting REE-signal from fossil francolite is the sum of vital and post-mortem incorporation. The necessary charge compensation for the substitution of divalent Ca by trivalent REE being done by different kind of electron defects and defect ions.

    Plant photosynthesis increases with solar radiation. Recent studies have shown that photosynthesis is more efficient under diffuse light conditions (Gu et al., 2003, Niyogi et al., 2004, Oliveira et al., 2007, Roderick et al., 2001). Changes in cloud cover and atmospheric aerosol loadings from either volcanic and anthropogenic sources, modify the total radiation reaching the surface and the fraction of this radiation which is diffuse, with uncertain overall effects on plant productivity and the global land carbon sink. A decrease in total solar radiation (Liepert, 2002, Stanhill and Cohen, 2001, Wild et al., 2005) has been observed at the Earth surface over the 1950-1990 period, called solar dimming. Such dimming gradually started to transform into brightening in some regions of the world since the late 1980s (Wild et al. 2005). The effect of these changes in total solar radiation and associated changes in diffuse radiation and diffuse fraction on the land biosphere has not yet been accounted for in global carbon cycle simulations because such models lack the mechanism that includes the diffuse irradiance effects on photosynthesis In this study we estimate the total impact of variations in clouds and atmospheric aerosols on the land carbon sink using a global land carbon cycle model modified to account for the effects of variations in both direct and diffuse radiation on canopy photosynthesis (Mercado et al., 2007) during the global dimming and brightening period.

    Recent observational and theoretical studies have shown that changes in surface radiation that lead to increasing diffuse surface irradiance, enhance plant photosynthesis (Gu et al., 2003, Niyogi et al., 2004, Oliveira et al., 2007, Roderick et al., 2001). Solar radiation reaching the land surface has changed over the industrial era due to aerosols emitted from volcanoes and various anthropogenic sources (Kvalevag and Myhre, 2007). Such changes in total surface radiation are accompanied by changes in direct and diffuse surface solar radiation. Current global climate-carbon models do include the effects of changes in total surface radiation on the land biosphere but neglect the positive effects of increasing diffuse fraction on plant photosynthesis. In this study we estimate for the first time, the impact of variations in diffuse fraction on the land carbon sink using a global model (Mercado et al., 2007) modified to account for the effects of variations in both direct and diffuse radiation on canopy photosynthesis. We use meteorological forcing from the Climate Research Unit Data set. Additionally short wave and photosynthetic active radiation are reconstructed from the Hadley centre climate model, which accounts for the scattering and absorption of light by tropospheric and stratospheric aerosols and change in cloud properties due to indirect aerosol effects.

    El impacto de la variabilidad y cambio climáticos, afectan el potencial agrícola de la Región Sur de Tamaulipas. Además de los cambios estacionales, bajos rendimientos agrícolas, el manejo de los cultivos y las políticas locales de producción, existe la incertidumbre del mercado regional para los pequeños y grandes productores. La diversificación agrícola ha sido una alternativa para enfrentar las condiciones imperantes en esta región. Pero ésta ha provocado la fragmentación territorial, por lo que sólo algunos productores logran competir en un mercado nacional. Existe una preocupación generalizada por buscar soluciones que permitan que la población que es afectada por la inseguridad de la producción agrícola y económica, pueda adaptarse a las variaciones climáticas que afectan el proceso productivo. La seguridad alimentaría queda sujeta a la fluctuación de las importaciones para los sectores básicos y a las estrategias mercantiles de empresas trasnacionales. La percepción local sugiere un número creciente de eventos climatológicos extremos, constantes y severos en los últimos 20 años, con el aumento creciente de pérdidas económicas. El análisis se centra en la disponibilidad de agua, agregándose un aspecto de capital importancia como es la variabilidad interanual de la lluvia, que condiciona muy fuertemente el riesgo agrícola en el trópico seco, siendo ésta la que determina el momento de inicio de la estación favorable para el crecimiento y su duración. En este trabajo se han obtenido modelos de la distribución espacial de la precipitación y temperaturas, para el escenario base 1961-1990, el escenario actual 1971-2000, para algunos años El Niño y La Niña, así como para los escenarios de Cambio Climático HADLEY, ECHAM y GFDL, con escenarios A2 y B2, para las décadas de los 20s y 50s, para establecer el inicio y duración de la Estación de Crecimiento, utilizando Sistemas de Información Geográfica (ArcView).

    The results of an AMS analysis carried on 36 sites from a late Miocene - Holocene volcanic stratigraphic sequence from the eastern Trans-Mexican Volcanic Belt is presented. 22 sites (450 samples) belong to lava flows, mainly of basaltic composition, from different emission centers from the Xalapa Monogenitc Volcanic Field, (Rodríguez et al 2010, González-Mercado, 2005), "Cofre de Perote Vent Cluster" (CPVC), "Naolinco Volcanic Field" (NVF), (Siebert and Carrasco-Núñez, 2002), and the Chiconquiaco-Palma Sola volcanic complex (López-Infanzón, 1991; Ferrari et al., 2005). 14 sites belong to the widely distributed El Castillo rhyolitic ignimbrite dated 2.44 to 2.21 Ma (Morales-Barrera, 2009) which is a non-welded to welded ignimbrite. AMS measurements were performed with a KLY2 Kappabridge and processed with Anisoft software using Jelinek statistics. Sometimes a density distribution analysis was also performed when magnetic fabric showed more dispersed distribution patterns. AMS ellipsoids from basalt sites show mostly prolate shapes, while those from ignimbrites show mostly oblate shapes, which may partly due to magnetic mineralogy and also to flow dynamics. Flow directions were mostly obtained from the imbrication angle of magnetic foliation (evaluated from kmin axis mean as corresponding to its pole) and considering the symmetry of the axes distribution. Flow direction inferences are discussed in relation with flow source when it is clearly evident from geologic field observations, as it is usually the case with basalt lava flows. While in ignimbrites, flow inferences from petrographic and facies distributions are compared with AMS flow inferences, showing agreement between them in some cases but not in others, may be due to local tilting occurring after ignimbrite emplacement.

  20. Response of Two Plant Species to Two Ultraviolet-B Radiation Regimes

    The depleted stratospheric ozone layer has been directly linked to increased levels of ultraviolet radiation at the earth's surface. It is important to understand what effect this will have on plants. We tested the hypothesis that in response to increased UV-B radiation (280-320 man), soybean (Glycine max Merrill) and alfalfa (Mercado Saliva L.) would produce higher concentrations of flavonoids than plants screened from UV-B. Soybean and alfalfa plants were grown successively in a growth chamber that provided UV-B radiation intensities 45% above summer field levels. A wooden frame was used to suspend mylar-D film over one group of plants and mono-acetate film over another group. Mylar is opaque in the 280-316 nm range, and acetate absorbs most radiation from 280-290 nm and then reduces intensities in the 290-320 nm range by roughly 15%. Leaf chlorophyll concentration was determined with a Minolta SPAD-502 chlorophyll meter; the BRAD meter was calibrated with N,N- extractions. Flavonoids were extracted with an acidified methanol/water solution. Soybean grown under the acetate treatment showed 26% smaller internodal lengths and higher concentrations of flavonoids compared to plants grown under mylar. Significant results for alfalfa included 22% greater leaf flavonoid concentration under acetate, 14% greater leaf chlorophyll concentration under mylar, and 32% greater above-ground biomass under mylar. We found that increased UV-B radiation leads to increased production of UV-B absorbing compounds (i.e. flavonoids) in soybean and alfalfa leaves. This suggests that a protective mechanism in these plants is triggered by UV-B. In response, flavonoids are produced that absorb UV-B, and consequently decrease potentially damaging effects to the plants. In addition, we hypothesize that this flavonoid protection mechanism saturates at certain UV-B intensities.

    The aim of this paper is to evaluate the respective roles of past changes in climate, geomorphology and human activities in shaping the present-day forest-savannah mosaic of the Bolivian Amazon, and consider how this palaeoecological perspective may help inform conservation strategies for the future. To this end, we review a suite of palaeoecological and archaeological data from two distinct forest-savannah environments in lowland Bolivia: Noel Kempff Mercado National Park (NKMNP) on the Precambrian Shield and the 'Llanos de Moxos' in the Beni basin. We show that they contain markedly contrasting legacies of past climatic, geomorphic and anthropogenic influences between the last glacial period and the Spanish Conquest. In NKMNP, increasing precipitation caused evergreen rainforest expansion, at the expense of semi-deciduous dry forest and savannahs, over the last three millennia. In contrast, pre-Hispanic indigenous cultures were instrumental in facilitating recent forest expansion in the Llanos de Moxos by building a vast network of earthworks. Insights from Mid-Holocene palaeodata, together with ecological observations and modelling studies, suggest that there will be progressive replacement of rainforest by dry forest and savannah in NKMNP over the twenty-first century in response to the increased drought predicted by general circulation models. Protection of the latitudinal landscape corridors may be needed to facilitate these future species reassortments. However, devising appropriate conservation strategies for the Llanos de Moxos will be more difficult due to its complex legacy of Palaeo-Indian impact. Without fully understanding the degree to which its current biota has been influenced by past native cultures, the type and intensity of human land use appropriate for this landscape in the future will be difficult to ascertain.

    Rare earth element (REE)-enriched, igneous-related hydrothermal Fe-oxide hosted (Fe-P-REE) systems from four areas in North America have been analyzed for their neodymium iosotopic composition to constrain REE sources and mobility in these systems. The Nd isotopic results evidence a common pattern of REE concentration from igneous sources despite large differences in age (Proterozoic to Tertiary), tectonic setting (subduction vs. intraplate), and magmatic style (mafic vs. felsic). In the Middle Proterozoic St. Francois Mountains terrane of southeastern Missouri, {epsilon}{sub Nd} for Fe-P-REE (apatite, monazite, xenotime) deposits ranges from +3.5 to +5.1, similar to associated felsic to intermediate igneous rocks of the same age ({epsilon}{sub Nd} = +2.6 to +6.2). At the mid-Jurassic Humboldt mafic complex in western Nevada, {epsilon}{sub Nd} for Fe-P-REE (apatite) mineralization varies between +1.1 and +2.4, similar to associated mafic igneous rocks ({minus}1.0 to +3.5). In the nearby Cortez Mountains in central Nevada, mid-Jurassic felsic volcanic and plutonic rocks ({epsilon}{sub Nd} = {minus}2.0 to {minus}4.4) are associated with Fe-P-REE (apatite-monazite) mineralization having similar {epsilon}{sub Nd}({minus}1.7 to {minus}2.4). At Cerro de Mercado, Durango, Mexico, all assemblages analyzed in this Tertiary rhyolite-hosted Fe oxide deposit have identical isotopic compositions with {epsilon}{sub Nd} = {minus}2.5. These data are consistent with coeval igneous host rocks being the primary source of REE in all four regions, and are inconsistent with a significant contribution of REE from other sources. Interpretations of the origin of these hydrothermal systems and their concomitant REE mobility must account for nonspecialized igneous sources and varied tectonic settings.

    The paucity of modern pollen-rain data from Amazonia constitutes a significant barrier to understanding the Late Quaternary vegetation history of this globally important tropical forest region. Here, we present the first modern pollen-rain data for tall terra firme moist evergreen Amazon forest, collected between 1999 and 2001 from artificial pollen traps within a 500 × 20 m permanent study plot (14°34'50″S, 60°49'48″W) in Noel Kempff Mercado National Park (NE Bolivia). Spearman's rank correlations were performed to assess the extent of spatial and inter-annual variability in the pollen rain, whilst statistically distinctive taxa were identified using Principal Components Analysis (PCA). Comparisons with the floristic and basal area data of the plot (stems ≥10 cm d.b.h.) enabled the degree to which taxa are over/under-represented in the pollen rain to be assessed (using R-rel values). Moraceae/Urticaceae dominates the pollen rain (64% median abundance) and is also an important constituent of the vegetation, accounting for 16% of stems ≥10 cm d.b.h. and ca. 11% of the total basal area. Other important pollen taxa are Arecaceae (cf. Euterpe), Melastomataceae/Combretaceae, Cecropia, Didymopanax, Celtis, and Alchornea. However, 75% of stems and 67% of the total basal area of the plot ≥10 cm d.b.h. belong to species which are unidentified in the pollen rain, the most important of which are Phenakospermum guianensis (a banana-like herb) and the key canopy-emergent trees, Erisma uncinatum and Qualea paraensis.

    Introducción: una dieta vegetariana puede satisfacer las necesidades nutricionales si está bien planificada. En este sentido, los vegetarianos deben ser aconsejados para elegir alimentos alternativos a los productos de origen animal seleccionando el tamaño de porción adecuada de cada uno de ellos. El valor nutricional de las porciones de los alimentos vegetales tradicionales es bien conocido, sin embargo, el mercado vegetariano ofrece otros productos cuya composición química es menos conocida, ya que no son alimentos ampliamente consumidos por la población. Es necesario conocer tanto el contenido de nutrientes de las porciones de estos alimentos como la biodisponibilidad de estos nutrientes en la dieta vegetariana. Objetivos: este trabajo tiene como objetivo mejorar la información disponible sobre el aporte nutricional a la dieta de un adulto sano de las porciones de alimentos utilizados por la población vegetariana. Además, se discuten algunos puntos sobre la biodisponibilidad de los nutrientes más relevantes, y se proponen alternativas para mejorar su utilización. Métodos: los datos de composición de los alimentos veganos, por 100 g, se buscaron en bases de datos de composición de alimentos, y a partir de ellos se calculó la composición química de las porciones. Después, estos datos nutricionales se compararon con las ingestas dietéticas de referencia europeas para la población adulta, y se discutió la biodisponibilidad de los nutrientes más importantes.

  8. Increased diffuse radiation fraction does not significantly accelerate plant growth

    NASA Astrophysics Data System (ADS)

    Angert, Alon; Krakauer, Nir

    2010-05-01

    A recent modelling study (Mercado et al., 2009) claims that increased numbers of scattering aerosols are responsible for a substantial fraction of the terrestrial carbon sink in recent decades because higher diffuse light fraction enhances plant net primary production (NPP). Here we show that observations of atmospheric CO2 seasonal cycle and tree ring data indicate that the relation between diffuse light and NPP is actually quite weak on annual timescales. The inconsistency of these data with the modelling results may arise because the relationships used to quantify the enhancement of NPP were calibrated with eddy covariance measurements of hourly carbon uptake. The effect of diffuse-light fraction on carbon uptake could depend on timescale, since this effect varies rapidly as sun angle and cloudiness change, and since plants can respond dynamically over various timescales to change in incoming radiation. Volcanic eruptions, such as the eruption of Mount Pinatubo in 1991, provide the best available tests for the effect of an annual-scale increase in the diffuse light fraction. Following the Pinatubo Eruption, in 1992 and 1993, a sharp decrease in the atmospheric CO2 growth rate was observed. This could have resulted from enhanced plant carbon uptake. Mercado et al. (2009) argue that largely as a result of the (volcanic aerosol driven) increase in diffuse light fraction, NPP was elevated in 1992, particularly between 25° N-45° N where annual NPP was modelled to be ~0.8 PgC (~10%) above average. In a previous study (Angert et al., 2004) a biogeochemical model (CASA) linked to an atmospheric tracer model (MATCH), was used to show that a diffuse-radiation driven increase in NPP in the extratropics will enhance carbon uptake mostly in summer, leading to a lower CO2 seasonal minimum. Here we use a 'toy model' to show that this conclusion is general and model-independent. The model shows that an enhanced sink of 0.8 PgC, similar to that modelled by Mercado et al. (2009

    Given the importance of Amazon rainforest in the global carbon and hydrological cycles, there is a need to use parameterized and validated ecosystem gas exchange and vegetation models for this region in order to adequately simulate present and future carbon and water balances. Recent research has found major differences in above-ground net primary productivity (ANPP), above ground biomass and tree dynamics across Amazonia. West Amazonia is more dynamic, with younger trees, higher stem growth rates and lower biomass than central and eastern Amazon (Baker et al. 2004; Malhi et al. 2004; Phillips et al. 2004). A factor of three variation in above-ground net primary productivity has been estimated across Amazonia by Malhi et al. (2004). Different hypotheses have been proposed to explain the observed spatial variability in ANPP (Malhi et al. 2004). First, due to the proximity to the Andes, sites from western Amazonia tend to have richer soils than central and eastern Amazon and therefore soil fertility could possibly be highly related to the high wood productivity found in western sites. Second, if GPP does not vary across the Amazon basin then different patterns of carbon allocation to respiration could also explain the observed ANPP gradient. However since plant growth depends on the interaction between photosynthesis, transport of assimilates, plant respiration, water relations and mineral nutrition, variations in plant gross photosynthesis (GPP) could also explain the observed variations in ANPP. In this study we investigate whether Amazon GPP can explain variations of observed ANPP. We use a sun and shade canopy gas exchange model that has been calibrated and evaluated at five rainforest sites (Mercado et al. 2009) to simulate gross primary productivity of 50 sites across the Amazon basin during the period 1980-2001. Such simulation differs from the ones performed with global vegetation models (Cox et al. 1998; Sitch et al. 2003) where i) single plant functional

Métodos: adultos procedentes del noroeste de Marruecos y sur de España (n = 400), completaron un cuestionario semi-cuantitativo de frecuencia de consumo de alimentos. Se analizó agua envasada consumida por la población y comprada en el mercado local (17 marcas/ tipos en Marruecos y 30 en el sur de España). Resultados: por cromatografía de intercambio iónico se analizaron diversas sales. El rango fue: Ca entre 140,16 y 439 mg/L; Mg entre 53,15 y 87,5 mg/L; Na entre 1169,78 y 257,2 mg/L y K 50,26 y 26,5 mg/L, valores tanto para muestras españolas como marroquís. Son aguas de mineralización media y su ingesta de minerales no contribuye más del 7% a la RDA de las poblaciones estudiadas. El seguimiento de la DM es superior en la población española (6,28 ± 1,38) que en la marroquí (4,42 ± 1,52). El perfil de ingesta de bebidas permite clasificar a la población al encontrar valores OR que van desde 1,6 a 11,01 para mayor ingesta de zumo, refrescos, te, agua envasada y total de ingesta de líquidos para la población marroquí frente a la española. Conclusión: el consumo de aguas envasadas no supone un suplemento mineral de interés en estas poblaciones.

Sin embargo, no existen estudios que cuantifiquen su disponibilidad comercial, composición e información detallada para poder estimar su impacto sobre las ingestas, particularmente de folatos, en los diferentes grupos de población. Objetivos: La finalidad de este trabajo de investigación ha consistido en conocer la disponibilidad actual de alimentos ready-to-eat de base vegetal y aportar datos sobre el contenido de folato total de los mismos. Métodos: La concentración de folato total se determinó en 17 productos precocinados refrigerados, con ingredientes vegetales, mediante el método microbiológico basado en el crecimiento del Lactobacillus casei subespecie rhamnosus resistente a cloranfenicol. La precisión del procedimiento analítico se comprobó mediante un material de referencia certificado y por una prueba de recuperación con ácido fólico tritiado. Resultados y discusión: El contenido medio de FT varió desde 13,6 hasta 103,8 μg/100 g de peso fresco, siendo superior en hamburguesas vegetales, recetas con garbanzos, guisantes o alcachofas con jamón. Los alimentos se sometieron al tratamiento térmico indicado por el fabricante previo a su consumo, observándose que no existen pérdidas de folatos durante este último procesado. El coeficiente de variación de los duplicados del mismo producto fue inferior al 15%. Conclusiones: Se presentan datos pioneros relativos al análisis de folatos en alimentos ready-to-eat en el mercado español, que ayudarán a evaluar la adecuación de la ingesta de folatos en la población. El contenido de folatos de estos productos, su facilidad de consumo y atractiva presentación, los convierte en fuentes potenciales de la vitamina.

    Background: Previous studies suggest that blood lead levels are positively associated with attention deficit/hyperactivity disorder (ADHD) and ADHD-symptoms in children. However, the associations between lead exposure and ADHD subtypes are inconsistent and understudied. Objective: The objective of this study was to explore the association of low-level concurrent lead exposure with subtypes of ADHD symptoms in 578 Mexican children 6–13 years of age. Methods: We measured concurrent blood lead levels using inductively coupled plasma mass spectrometry (ICPMS). We administered the Conners’ Rating Scales-Revised (CRS-R) to mothers to evaluate their children’s ADHD symptoms. We used imputation to fill missing values in blood lead levels and used segmented regression models adjusted for relevant covariates to model the nonlinear relationship between blood lead and ADHD symptoms. Results: Mean ± SD blood lead levels were 3.4 ± 2.9 μg/dL. In adjusted models, a 1-μg/dL increase in blood lead was positively associated with Hyperactivity and Restless-Impulsivity scores on the CRS-R scale and Hyperactivity-Impulsivity scores on the CRS-R scale of the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, but only in children with blood lead level ≤ 5 μg/dL. Blood lead was not associated with Inattentive symptoms or overall ADHD behavior. Conclusions: In this population of Mexican children, current blood lead level among children with low exposure (≤ 5 μg/dL) was positively associated with hyperactive/impulsive behaviors, but not with inattentiveness. These results add to the existing evidence of lead-associated neurodevelopmental deficits at low levels of exposure.

    Background: Human milk is a potential source of lead exposure. Yet lactational transfer of lead from maternal blood into breast milk and its contribution to infant lead burden remains poorly understood. Objectives: We explored the dose–response relationships between maternal blood, plasma, and breast milk to better understand lactational transfer of lead from blood and plasma into milk and, ultimately, to the breastfeeding infant. Methods: We measured lead in 81 maternal blood, plasma, and breast milk samples at 1 month postpartum and in 60 infant blood samples at 3 months of age. Milk-to-plasma (M/P) lead ratios were calculated. Multivariate linear, piecewise, and generalized additive models were used to examine dose–response relationships between blood, plasma, and milk lead levels. Results: Maternal lead levels (mean ± SD) were as follows: blood: 7.7 ± 4.0 μg/dL; plasma: 0.1 ± 0.1 μg/L; milk: 0.8 ± 0.7 μg/L. The average M/P lead ratio was 7.7 (range, 0.6–39.8) with 97% of the ratios being > 1. The dose–response relationship between plasma lead and M/P ratio was nonlinear (empirical distribution function = 6.5, p = 0.0006) with the M/P ratio decreasing by 16.6 and 0.6 per 0.1 μg/L of plasma lead, respectively, below and above 0.1 μg/L plasma lead. Infant blood lead level (3.4 ± 2.2 μg/dL) increased by 1.8 μg/dL per 1 μg/L milk lead (p < 0.0001, R2 = 0.3). Conclusions: The M/P ratio for lead in humans is substantially higher than previously reported, and transfer of lead from plasma to milk may be higher at lower levels of plasma lead. Breast milk is an important determinant of lead burden among breastfeeding infants.

    Introducción: En los últimos años, el campo de los probióticos ha experimentado un gran auge. Sin embargo, de los miles de cepas aisladas cada año por su potencial probiótico en los laboratorios de todo el mundo, muy pocas pasan a una fase de desarrollo industrial y menos aún son las que consiguen una vida comercial. Objetivo: En este artículo, se revisan los principales aspectos que se deben tener en cuenta en el, habitualmente, largo y tortuoso camino que debe seguir una cepa desde su aislamiento inicial hasta su comercialización. Resultados y conclusiones: Cualquier microorganismo probiótico debe estar correctamente identificado a nivel de especie y cepa. La secuencia del genoma es la mejor identificación posible, además de proporcionar información muy valiosa sobre su seguridad, funcionalidad y propiedades de interés tecnológico. Los casos en los que se ha podido establecer una relación entre un probiótico y un efecto adverso son muy escasos y han afectado a personas con patologías subyacentes. Globalmente, aunque las distintas pruebas in vitro, ex vivo y en modelos animales proporcionan información útil durante el proceso de selección de cepas, los únicos datos que permiten evaluar la seguridad y eficacia de un probiótico de una forma directa son los que se obtienen en el curso de ensayos clínicos correctamente diseñados y dirigidos específicamente a la población diana. Por otra parte, las empresas que comercializan probióticos tienen la necesidad de obtener una biomasa muy elevada de forma económicamente rentable y de que la concentración de bacterias viables necesaria para ejercer el efecto beneficioso se mantenga hasta el final de la vida útil del producto. Finalmente, los aspectos comerciales son determinantes en la decisión de afrontar el desarrollo industrial y la puesta en el mercado de un probiótico.

    The article analyzes the configuration and trends in institutions of Higher Education and their relationship as components of the Health Economic-Industrial Complex (HEIC). The expansion of higher education is part of the transition from elite to mass systems, with tensions between quantitative and qualitative aspects. Such changes reflect different cultures and are related to international phenomena such as globalization, economic transformations, the development of new information and communication technologies, and the emergence of an international knowledge network. The scale and content of these changes vary according to the expansion and institutional reconfiguration of educational systems, as well as the link between state and society. Market expansion for private higher education stirs competition, shapes business clusters, modifies training processes, and raises new public policy challenges. Resumo: Este artigo analisa a configuração e as tendências das instituições de Ensino Superior de saúde no seu relacionamento enquanto componentes do Complexo Econômico Industrial da Saúde (CEIS). A expansão do Ensino Superior é parte da transição de sistemas de elite para sistemas de massa, com tensionamentos entre aspectos quantitativos e qualitativos. Essas mudanças refletem diferentes culturas e se relacionam com fenômenos de escopo mundial como globalização, transformações econômicas, desenvolvimento de novas tecnologias de comunicação e informação, e emergência de uma rede internacional de conhecimento. A escala e o conteúdo dessas mudanças variam com a ampliação dos sistemas de ensino e na reconfiguração institucional, bem como na articulação entre Estado e sociedade. A ampliação do mercado privado no ensino acirra a competitividade, conformando conglomerados empresariais, alterando processos de formação e forjando novos desafios para as políticas públicas.

    Introdução: Todos os medicamentos de uso humano são comercializados com um folheto informativo. Estes documentos devem ter uma lista inicial com a identificação de todas as secções, de acordo com o modelo europeu Quality Review of Documents e não serem muito extensos, i.e. com cerca de 1500 palavras. Apenas excepcionalmente são autorizados folhetos relativos a mais de uma dose e/ ou forma farmacêutica (folhetos mistos). Neste contexto, os objectivos incluem a identificação de problemas nos folhetos informativos de todos os medicamentos não genéricos portugueses quanto à presença da lista inicial, à frequência de folhetos mistos e ao número de páginas. Material e Métodos: Consulta dos folhetos na base pública Infomed de acordo com a classificação do Prontuário Terapêutico – 10 (1º trimestre 2012). Os dados recolhidos foram sujeitos a controlo de qualidade e tratamento estatístico. Resultados: Identificação de 2729 folhetos em 3080 especialidades farmacêuticas. Foram avaliados 2042 folhetos (687 não estavam disponíveis), em que 181 (8,9%) não apresentaram lista inicial e 351 (17,2%) eram mistos. O número médio de páginas foi 6,9 (DP = 2,6), o mínimo = 2 e o máximo = 26. Discussão: A leitura e compreensão adequadas dos folhetos portugueses em alguns casos podem estar comprometidas, dado que 1) alguns dos folhetos analisados não continham a lista inicial necessária à adequada localização das informações, 2) foram detetados folhetos mistos e/ou 3) foram encontrados folhetos com uma extensão acima do desejável. Conclusão: Os resultados deste estudo devem informar o processo de desenvolvimento e aprovação dos folhetos pelos titulares da autorização da introdução no mercado e pelas autoridades reguladoras.

    Antecedentes: en la consulta de Alergología se realiza un tamizaje rutinario con diversos alergenos, entre ellos: mohos, alimentos, cucarachas y ácaros, que logra diagnosticar a gran parte de los pacientes atendidos. Sin embargo, hay individuos con síntomas de alergia que resultan negativos en las pruebas por punción con los alergenos disponibles en el mercado. Las trampas de luz UV que se colocan en el Valle Inter-montano Central de Costa Rica para mosquitos muestran una gran cantidad de captura de lepidópteros nocturnos, lo que motivó a pensar en la importancia de la alergenicidad de este género de nivel de la región tropical húmeda. Objetivos: determinar el porcentaje de pacientes sensibilizados a los lepidópteros nocturnos y dar a conocer la importancia de estos insectos como alergenos ambientales. Material y método: análisis retrospectivo de los expedientes de la Sección de Alergología de la Clínica Médica Herediana, Heredia, Costa Rica, de febrero de 2011 a febrero de 2012 para determinar el porcentaje de pacientes alérgicos a los lepidópteros nocturnos, a los ácaros de polvo doméstico (Blomia tropicalis, Dermatophagoides pteronyssinus, Dermatophagoides farinae y Tyrophagus putrescentiae) y a insectos (Periplaneta americana y Musca domestica). A su vez, se analizaron los aspectos demográficos y los síntomas de los pacientes. Resultados: se incluyeron 347 pacientes (217 mujeres y 130 hombres, 36.32 ± 18.10 años). El 63% de los pacientes eran alérgicos a los ácaros del polvo doméstico, 39% a los lepidópteros nocturnos, 28% a Periplaneta americana y 24% a Musca domestica. El 2% de los pacientes alérgicos a sólo un alergeno estaba monosensibilizado contra los alergenos de los lepidópteros nocturnos. Conclusión: se recomiendan las pruebas continuas de alergia a lepidópteros nocturnos, porque son los insectos a los que la mayoría de los pacientes estudiados tuvo alergia.

    This article has two parts. The first discusses the relationship between industry and health interests based on three different but non-mutually exclusive "logics": (a) independent; (b) divergent; and (c) convergent. The second part describes the experience at the Brazilian National Institute of Traumatology and Orthopedics (INTO) with a technology management model. The accumulated expertise in orthopedics at INTO can favor Brazil's domestic medical equipment industry without jeopardizing the country's social health needs. This means directing the production of feasible technologies adapted to the national reality, with a focus on safety and quality, without burdening the public coffers and by overcoming the country's dependency on imported products. The proposal is to promote socioeconomic development through a virtuous circle by attracting reserves and fomenting national competitiveness in domestic and foreign markets while improving social conditions and access to health. Resumo: Este artigo está dividido em duas partes. Na primeira, discute-se como se relacionam os interesses produtivos e a saúde a partir de três "lógicas" ou perspectivas diferentes que não são mutuamente excludentes: (a) independente; (b) divergente e (c) convergente. Na segunda, descreve-se a experiência do Instituto Nacional de Traumatologia e Ortopedia (INTO) na montagem de um modelo de gestão de tecnologia. O conhecimento internalizado em ortopedia do INTO pode favorecer a indústria nacional de equipamentos médicos sem abandonar as necessidades sociais brasileiras de saúde. Isto é, direcionar a produção de tecnologias viáveis e adaptadas à realidade nacional, com foco em segurança e qualidade, sem onerar os cofres públicos e abandonando a dependência de produtos importados. A proposta é a de promover um desenvolvimento socioeconômico que construa um ciclo virtuoso, por atrair divisas e fomentar a competitividade nacional em mercados internos e externos, melhorando as

    para poder llegar a conclusiones validas. Por ello, se ha adoptado como nucleo de este trabajo la definicion de libro de texto basada en su destino y no en su funcion, es decir, los libros que de forma explicita expresan su finalidad didactica, tanto en el titulo o como en las declaraciones del autor reflejadas en el prologo de la obra, en los que ademas aparezca la palabra quimica en su titulo. El estudio comienza en 1788 con la publicacion de algunos de los primeros manuales de quimica modernos, y acaba con la reforma educativa de 1845, que tuvo importantes consecuencias en el mercado de libros de texto en Espana. Esta reforma separaba la ensenanza media de la propiamente universitaria y, de este modo, fue impulsora de la creacion de institutos provinciales de segunda ensenanza, algunos de los cuales habian comenzado su andadura en los anos anteriores. Las regulaciones introducidas suponian una fuerte limitacion para los profesores en la eleccion de los manuales de ensenanza que debian ser aprobados cada tres anos por el Consejo de Instruccion Publica. Ademas supuso una reglamentacion clara de los estudios de filosofia y su division en los estudios elementales y superiores. La investigacion se ha distribuido a lo largo de seis capitulos: Introduccion, los protagonista, el vocabulario de la quimica, poniendo orden: las clasificaciones quimicas, conclusiones y apendice. En primer lugar, se ha elaborado un repertorio bibliografico, incluido en el apendice, constituido por 76 obras de quimica publicadas en Espana desde 1788 hasta 1845 que permite realizar un analisis estadistico de su produccion. Posteriormente, se intenta conocer los principales protagonistas en la creacion del libro: editores, impresores, autores, traductores y lectores. Tradicionalmente los historiadores de la ciencia han dado mas importancia a los laboratorios y a los personajes de la investigacion cientifica, frente a las aulas y a los protagonistas de la ensenanza.

    Resumen Durante cinco años, un torbellino cotidiano de tiroteos, apuñalamientos y asaltos afectó a la venta de drogas al aire libre en el vecindario puertorriqueño de Filadelfia, donde residíamos y conducíamos nuestro trabajo de campo. La industria de los narcóticos ha venido a llenar el vacío que dejó la desindustrialización, convirtiendo al antiguo distrito fabril de la ciudad en un mercado de narcóticos a cielo abierto que emplea en sus niveles más bajos a jóvenes puertorriqueños y cuyos clientes son principalmente heroinómanos blancos de bajos recursos. La capacidad para movilizar la furia asegura el éxito en la economía de las drogas, garantiza protección en las cárceles y le provee un ingreso mínimo a una población de bajos recursos estigmatizada cuyos miembros frecuentemente reciben diagnósticos médicos de discapacidad cognitiva. Muchos residentes buscan alianzas en redes sociales que los comprometen a participar en intercambios solidarios de violencia auxiliar. Una dinámica de acumulación primitiva corporizada mata, hiere, discapacita o encarcela a la mayoría de estos empleados de bajo nivel y a sus clientes. Los inflados márgenes de ganancia alrededor de esta dinámica dependen de la violencia y la coerción. Un habitus furibundo impulsa a los vendedores callejeros a defender violentamente el micro monopolio de poder de sus jefes en la economía subterránea como si fuese un asunto de diversión. Estos miembros de los niveles más bajos de la industria del narcotráfico se apresuran a fraguar transacciones comerciales en ausencia de un marco legal en un ambiente de escasez que sin embargo se ve inundado por enormes flujos de dinero, drogas adictivas y armas automáticas. Tras las drásticas reformas a los programas de seguridad social, la mano izquierda del Estado, en la forma de los servicios sociales, intenta prolongar los subsidios para individuos vulnerables diagnosticándolos como discapacitados cognitivos permanentes

    Two teachers from the town of San Pedro de Atacama, in the northern desert of the South American nation of Chile, arrive in Magdalena, New Mexico, Sunday, January 28, for a two-week visit that is part of a Sister Cities program sponsored by Associated Universities, Inc. (AUI), the nonprofit research corporation that operates the National Radio Astronomy Observatory (NRAO). They will be accompanied by their town's mayor. Myriam Nancy Rivera Mercado, Head of the high school in San Pedro, Gabriela Fernanda Rodriguez Moraleda, a tourism teacher there, and San Pedro Mayor Sandra Berna Martinez will begin a visit that includes classroom observations in the Magdalena schools, a reception hosted by the Magdalena Village Council, and a Mayor's Breakfast with Magdalena Mayor Jim Wolfe. They also will meet local residents, tour the Bosque del Apache National Wildlife Refuge with a second-grade class, visit an area ranch, tour the Very Large Array (VLA) radio telescope, and see Socorro's Community Arts Party. "These teachers will learn much about New Mexico, the United States, and our educational system, and will take this new knowledge back to their students and their community," said NRAO Education Officer Robyn Harrison. The visit is part of a Sister Cities program initiated and funded by AUI, which operates the NRAO for the U.S. National Science Foundation. Radio astronomy is a common link between San Pedro de Atacama and Magdalena. San Pedro is near the site of the Atacama Large Millimeter/submillimeter Array (ALMA), an international telescope project now under construction with funding by major partners in North America, Europe, and Japan. Magdalena is near the site of NRAO's VLA radio telescope. In Magdalena, the Village Council and Mayor Wolfe formalized their participation in the Sister Cities program last September, and San Pedro ratified the program in December. In San Pedro, the ceremony ratifying the agreement was attended by U.S. Ambassador to Chile Craig K

    Introducción: El cáncer de pulmón es la tercera neoplasia tumoral más frecuente en España, con unos 27.000 nuevos casos/ año, de los que el 80-85% son de etiología no microcítica (NSCLC) y en la mayoría de los casos diagnosticados en estadíos avanzados de la enfermedad, razón por la que es uno de los procesos oncológicos con mayores tasas de mortalidad (supervivencia media a los 5 años del 21,4%). Los principales esquemas de primera línea utilizados en el tratamiento del NSCLC son: cisplatino/pemetrexed (cis/pem), cisplatino/gemcitabina/ bevacizumab (cis/gem/bev), y carboplatino/paclitaxel/bevacizumab (carbo/pac/Bev). El objetivo del presente trabajo consistirá en realizar un análisis para estimar el ratio coste-eficacia de los esquemas antineoplásicos de primera línea en el tratamiento del NSCLC, desde la perspectiva de la gerencia hospitalaria. Metodos: Se elaboró un modelo matemático de coste-eficacia basado en un árbol de decisiones. Como variable de eficacia se utilizó la supervivencia libre de progresión, obtenida de los ensayos clínicos fase III PARAMOUNT, AVAIL y SAIL. El estudio se efectuó desde la perspectiva de la gerencia hospitalaria considerando únicamente los costes directos de adquisición de los fármacos. Se realizó un análisis de sensibilidad determinístico para comprobar la robustez de los resultados. Resultados: La SLP obtenida en los ensayos clínicos de los tratamientos cis/pem, cis/gem/bev y carb/pac/bev fue de: 6,9, 6,7 y 6,2 meses, respectivamente. En base a nuestro modelo, el coste medio del tratamiento por paciente para estos esquemas fue de 19.942 €, 15.594 € y 36.095 €, respectivamente. La razón coste-eficacia incremenal por mes de SLP adicional entre cis/pem y cis/gem/bev fue de 19.303 €. Estimando una reducción del 30% de los costes de adquisición de pemetrexed (Alimta®Eli Lilly Nederland B.V) ante su próxima incorporación al mercado de medicamentos genéricos, el tratamiento cis/pem se

    ablation experiments results in considerably worse spatial resolution than that typically possible for 40Ar/39Ar laser microprobe dating, it is possible to site the LA-ICPMS ablation pit within a few microns of the pit used for He extraction, or to simply re-occupy and enlarge the original ablation pit. The potential effective spatial resolution of the technique is thus on the order of a few tens to roughly 100 microns. As a proof-of-concept exercise, we have applied this technique to fluorapatite from Cerro de Mercado, Durango, Mexico, which has a generally accepted (U-Th)/He age of 32.1 +/- 3.4 Ma (2 sigma) based on single-crystal fusion analyses reported by House et al. (2000, EPSL). Using the approach described above, we made 48 separate age measurements on a 12 mm polished section cut through a single crystal of Durango fluorapatite perpendicular to its c axis. The measured dates yield a mean of 34.9 +/- 5.1 Ma (2 sigma), with a total dispersion of dates comparable to that reported by House et al. Much of the apparent age variation observed in both studies is due to documented U+Th heterogeneities in single crystals of the Durango fluorapatite. Nevertheless, the consistency of the laser ablation and conventional results for this material is striking. Compared to conventional laser and furnace methods of (U-Th)/He geochronology, the laser microprobe approach offers substantially improved spatial resolution, and the ability to avoid (or at least minimize) alpha-ejection corrections. In addition, the method affords improved sample throughput, such that age estimates for homogeneous materials can be made with considerably higher precision based on a larger number of analyses.

El Grano de los Datos de Costo Económico con Referencia Espacial y de Beneficio a la Biodiversidad y la Efectividad de una Estrategia de Determinación de Costos Resumen Entre 1990 y 2007, en promedio fueron cazados ilegalmente cada año 15 rinocerontes sureños blancos (Ceratotherium simum simum) y negros (Diceros bicornis) en Sudáfrica. Desde 2007 la caza ilegal de rinocerontes sureños blancos por su cuerno ha escalado a más de 950 individuos al año en 2013. Llevamos a cabo un análisis ecológico-económico para determinar si el comercio legal de cuerno de rinoceronte sureño blanco podría facilitar la protección del rinoceronte. Se usaron modelos lineales generalizados para examinar a los conductores socio-económicos de la caza furtiva, con base en datos colectados desde 1990 hasta 2013, y también para proyectar el número total de rinocerontes con probabilidad de ser cazados ilegalmente desde 2014 hasta 2023. Las dinámicas poblacionales de los rinocerontes fueron entonces modeladas bajo ocho escenarios políticos diferentes que podrían implementarse para controlar la caza furtiva. También estimamos los costos económicos y los beneficios de cada escenario solamente bajo la ejecución aumentada del plan de manejo y el comercio legal de cuerno de rinoceronte y usamos un marco de trabajo de apoyo a decisiones para ordenar los escenarios con el objetivo de mantener la población de rinocerontes por encima de su tamaño actual mientras se generan ganancias para los accionistas locales. Se predijo que la población de rinocerontes sureños blancos se extinguiría en menos de 20 años bajo el manejo actual. El escenario óptimo para mantener la población de rinocerontes por encima de su tamaño actual fue el de proporcionar un incremento mediano en el esfuerzo contra la caza furtiva e incrementar la multa monetaria de la condena. Sin legalizar el mercado, implementar tal escenario requeriría cubrir costos de aproximadamente $147, 000, 000 al año. Con

    potenciales de los pagos por servicios ambientales (PSA) y áreas protegidas (APs) sobre los resultados ambientales y las subsistencias locales en los países en desarrollo son polémicos y se han debatido ampliamente. La evidencia disponible es escasa; ha habido pocas evaluaciones rigurosas de los impactos ambientales y sociales de las APs y particularmente los PSA. Medimos el impacto sobre los bosques y el bienestar humano en tres diferentes programas de PSA que se llevan a cabo dentro de dos APs en el norte de Camboya usando un panel de aldeas de intervención y controles emparejados. Tanto los PSA como las APs brindaron resultados ambientales adicionales en relación a los contrafácticos, esto quiere decir que redujeron las tasas de deforestación significativamente en relación a los controles. Las áreas protegidas incrementaron el acceso seguro a los recursos del suelo y el bosque para las viviendas locales, beneficiando a los usuarios de los recursos del bosque pero restringiendo la habilidad de las viviendas para expandirse y diversificar su agricultura. Los impactos de los pagos por servicios ambientales sobre el bienestar de las viviendas estuvieron relacionados con la magnitud de los pagos proporcionados. Los dos programas de PSA de mayor paga y con conexión al mercado tuvieron impactos positivos significativos, mientras que un programa de menor paga con el objetivo de proteger a la biodiversidad no tuvo un efecto detectable sobre las viviendas, a pesar de sus resultados ambientales positivos. Las viviendas que se inscribieron a los programas de PSA con mayor paga, sin embargo, necesitaban típicamente más bienes capitales, por lo que eran menos pobres y tenían mayor seguridad alimentaria que otros aldeanos. Por esto, mientras los impactos de las APs sobre el bienestar de las viviendas fueron limitados en general y variaron dependiendo de las estrategias de subsistencia, los programas de PSA tuvieron impactos positivos significativos sobre las viviendas para

The proposed methodology can also be used to evaluate the quality of the model forcings: two soil moisture fields from ORCHIDEE using WATCH (Weedon et al., 2011) and ERA-interim (Balsamo et al., 2010) forcings were analysed. It was shown that the WATCH forcing data are more optimal, underlining the importance of forcing data for the accuracy of model predictions (Kolassa et al., in press, 2012).

    panel. Les 282 répondants étaient des immigrés en Finland provenant de l'ancienne Union Soviétique nés entre 1961 et 1976. Les résultats suggèrent que l'adaptation de ces immigrants s'est développée favorablement. En huit ans, les répondants avaient amélioré leurs habiletés en finlandais sur le marché de travail. Aucune différence n'a été observée dans leurs niveaux de bien-être psychologique entre les deux évaluations. Parmi les trois dimensions de l'adaptation évaluées, l'adaptation socio-culturelle telle que mesurée par la capacité de comprendre, de parler, de lire et d'écrire le finlandais s'est avérée être le prédicteur le plus significatif des deux autres résultats à long-terme de l'adaptation de l'immigré (i.e., socio-économique et psychologique). Particulièrement, meilleure avait été la connaissance initiale du finlandais, meilleurs étaient leurs résultats de l'adaptation socio-économiques et psychologiques après 8 ans de résidence. Ces résultats démontrent l'importance des évaluations parallèles et longitudinales de différents résultats de l'adaptation de l'immigré pour mieux étudier quelles dimensions particulières de l'adaptation sont les plus critiques au début de l'acculturation en matière de la détermination du développement positif et de l'adaptation à long-terme de l'immigré. El estudio consistió en una investigación longitudinal sobre tres diferentes dimensiones de adaptación de inmigrantes a largo plazo (i.e. adaptación psicológica, sociocultural, socioeconómica) y la relación entre ellas en 8 años de seguimiento con los datos de grupo. Los 282 encuestados fueron inmigrantes en Finlandia procedentes de los países de la antigua Union Sovietica, nacidos entre 1961 y 1976. Los resultados sugieren que la adaptación de estos inmigrantes se desarrolló favorablemente. En ocho años, los encuestados han mejorado sus conocimientos del idioma finlandes y su posición en el mercado laboral. No se

    and global temperature change are 12-month running means of differences for the same month of consecutive years. Nino index (Nino3.4 area) is 12-month running mean. Both temperature indices use data from Hansen et al (2010). Annual mean CO2 amount in 1958 was 315 ppm (Mauna Loa) and in 2012 was 394 ppm (Mauna Loa) and 393 ppm (Global). Interannual variability of CO2 growth is correlated with ENSO (El Nino Southern Oscillation) variations of tropical temperatures (figure 2). Ocean-atmosphere CO2 exchange is affected by ENSO (Chavez et al 1999), but ENSO seems to have a greater impact on atmospheric CO2 via the terrestrial carbon cycle through effects on the water cycle, temperature, and fire, as discussed in a large body of literature (referenced, e.g., by Schwalm et al 2011). In addition, volcanoes, such as the 1991 Mount Pinatubo eruption, slow the increase of atmospheric CO2 (Rothenberg et al 2012), at least in part because photosynthesis is enhanced by the increased proportion of diffuse sunlight (Gu et al 2003, Mercado et al 2009). Watson (1997) suggests that volcanic dust deposited on the ocean surface may also contribute to CO2 uptake by increasing ocean productivity. An important question is whether ocean and terrestrial carbon sinks will tend to saturate as human-made CO2 emissions continue. Piao et al (2008) and Zhao and Running (2010) suggest that there already may be a reduction of terrestrial carbon uptake, while Le Quéréet al (2007) and Schuster and Watson (2007) find evidence of decreased carbon uptake in the Southern Ocean and North Atlantic Ocean, respectively. However, others (Knorr 2009, Sarmiento et al 2010, Ballantyne et al 2012) either cast doubt on the reality of a reduced uptake strength or find evidence for increased uptake. An informative presentation of CO2 observations is the ratio of annual CO2 increase in the air divided by annual fossil fuel CO2 emissions (Keeling et al 1973), the 'airborne fraction' (figure 3, right scale).
