El presente trabajo busca hacer un análisis sobre los arreglos institucionales introducidos con la ley 100 de 1993 a las Empresas Sociales del Estado (ESE), y cómo estos han afectado la prestación del servicio de salud y la garantía del derecho; para lo cual se escoge como ejemplo el Hospital Simón Bolívar E.S.E de Bogotá durante los años 2002 a 2014. Se explica como con la implementación de la descentralización, el modelo de aseguramiento y la autonomía financiera se afectó la prestación del servicio de salud, teniendo en cuenta la introducción de un eslabón dentro del sistema de salud: las Empresas Promotoras de Salud (EPS).

El artículo, centrándose en el sector agrícola ecuatoriano, hace una descripción del estado en que se encuentran las negociaciones del Tratado de Libre Comercio entre Estados Unidos y Ecuador. De acuerdo con el autor, en el sector agrícola, manejado como tema sensible y relevante por parte de los negociadores ecuatorianos, el ritmo de negociación ha sido desgastante para la parte ecuatoriana debido, entre otras razones, a la inflexibilidad mostrada hasta el momento por parte de los negociadores norteamericanos. Igualmente plantea y analiza dos escenarios factibles una vez concluidas las rondas de negociación: que el Ecuador decida poner un freno al proceso de negociación o que el proceso negociador continúe y las condiciones actuales se flexibilicen, especialmente por parte de los EE.UU. para facilitar la firma del Tratado.

El siguiente trabajo tiene como objetivo estudiar las relaciones Estado-Iglesia en Colombia y Ecuador en el período comprendido entre 1830 y 1860, partiendo de la ley de patronato de 1824 como variable de comparación y de la aplicación que hicieron ambos países de dicha ley en los nombramientos eclesiásticos. El primer capítulo hace referencia al inicio de las relaciones Estado- Iglesia en la colonia, cómo se llevo a cabo la evangelización en estos países, qué tipo de conflictos se dieron, cuál fue la participación de la iglesia en el proceso de independencia y cómo se empezó a aplicar la ley de patronato en los nacientes estados y sus primeros conflictos. En el segundo capítulo entramos en la discusión acerca de los nombramientos eclesiásticos, la forma en que los países manejaron este asunto partiendo de la ley de patronato, su enfrentamiento con los parámetros utilizados por la iglesia y las diferentes soluciones que planteó cada país en el intento de terminar con la tensión Estado-Iglesia. El tercer capítulo localiza su estudio en el ámbito de los diezmos y las propuestas de supresión de este impuesto, que llegaría a convertirse en obstáculo para el desarrollo de la agricultura y la economía nacional. Finalmente dedicaremos un último espacio al tema de la educación como apartado del proyecto político que busca la constitución de una nación.

El presente trabajo de investigación tiene como objetivo averiguar si la agricultura sustentable puede ser una alternativa de desarrollo para el sector agrícola nacional, partiendo de la comprensión de los motivos principales por los que la agricultura ecuatoriana atraviesa una crisis que le imposibilita insertarse de manera efectiva dentro del contexto internacional. Con este fin, la tesis se ha dividido en cuatro capítulos: El primer capítulo investiga cuál ha sido la influencia del paradigma del crecimiento económico, el desarrollo y posteriormente la globalización comercial, en el sector agrícola nacional. A partir de ahí se identifican algunos de sus principales problemas. En el segundo capítulo, se efectúa un recorrido por el contexto internacional y la globalización, esencialmente los aspectos que más afectan a la agricultura ecuatoriano: la globalización del comercio, la difusión de tecnologías productivas agrícolas y los desafíos que la globalización impone al Estado. En el tercer capítulo se expone el planteamiento del desarrollo sustentable y en este contexto la propuesta de la agricultura sustentable hacia el desarrollo agrícola integral En el se habla de la agroecología y la apertura de los mercados internacionales a sus productos. Para observar las experiencias empíricas que en esta dirección se van dando en Ecuador, el capítulo cuarto se aproxima a algunas de ellas, por medio de entrevistas a instituciones promotoras y visitas a casos. A partir de este recorrido, se establecen conclusiones a manera de respuesta al cuestionamiento inicial, objetivo del presente trabajo.

This Study evaluated the species-level taxonomy and phylogenetic relationship among Kumanoa species from Brazil with other regions of the world based on the plastid-encoded RUBISCO large Subunit gene (rhcL). Partial rbcL sequences were obtained for 11 Kulnanoa specimens. Eight species are recognised from Brazil on the basis of molecular and morphological data: seven previously described (K abilii, K ambignia, K. breviarticulata, K. cipoensis, K. equisetoidea, K. globospora and K procarpa) and a new species here proposed (K. amazonensis sp. nov. Necchi & Vis). The new species has reduced and dense whorls but differs from the two closest related species in lacking secondary fascicles. Previously proposed infrageneric categories were not supported by the molecular data. Species described and endemic (K. breviarticulata, K. cipoensis, K equiseloidea and K. procarpa) to Brazil are not grouped together but are variously related to other species from North America, Europe and Australasia. With the species recognised in this study using molecular and morphological data and those previously distinguished by morphology, 13 species of Kumanoa are Currently documented from Brazil.

Roads facilitate access by deforestation agents, being relevant in studies approaching conservationist matters in rainforests. It is important to understand the relationship between road distribution, relief, land use, and forest coverage in order to evaluate where forests are more vulnerable. This study aimed at: 1) understanding the relationship between relief and density and road connectivity in three moments in time; and 2) evaluating the relationship between distance from roads and forest coverage, farmlands and rural and urban facilities in a fragmented Atlantic Forest landscape in three moments in time. Maps of roads, altitude, and land use and coverage were used. Chi-square tests showed that: 1) density and road connectivity did not present significant relationship with the relief; and 2) forest areas occupy areas distant from the roads, while farmlands and rural and urban facilities occupy areas nearer the roads. Roads and land use, regardless of relief, influence forest coverage distribution. Thus, we suggest that roads are taken into account in conservationist strategies and environmental planning.

A new species of cubozoan jellyfish has been discovered in shallow waters of Bonaire, Netherlands ( Dutch Caribbean). Thus far, approximately 50 sightings of the species, known commonly as the Bonaire banded box jelly, are recorded, and three specimens have been collected. Three physical encounters between humans and the species have been reported. Available evidence suggests that a serious sting is inflicted by this medusa. To increase awareness of the scientific disciplines of systematics and taxonomy, the public has been involved in naming this new species. The Bonaire banded box jelly, Tamoya ohboya, n. sp., can be distinguished from its close relatives T. haplonema from Brazil and T. sp. from the southeastern United States by differences in tentacle coloration, cnidome, and mitochondrial gene sequences. Tamoya ohboya n. sp. possesses striking dark brown to reddish-orange banded tentacles, nematocyst warts that densely cover the animal, and a deep stomach. We provide a detailed comparison of nematocyst data from Tamoya ohboya n. sp., T. haplonema from Brazil, and T. sp. from the Gulf of Mexico.

Pleistovultur nevesi, a new genus and species of a large Vulturidae is described from the Upper Pleistocene or beginning of the Holocene, based on a complete and well preserved right tibiotarsus from the Cuvieri cave deposits, one of the hundreds of caves of the Lagoa Santa region in Minas Gerais state, Brazil. Also described here is a distal half of a left tibiotarsus from Gruta dos Brejoes, a cave in Morro do Chapeu, Bahia state, Brazil, which probably belongs to another not-yet-known genus and species of the Vulturidae. The described material, added to prior literature, is proof of the appreciable diversity of the Vulturidae during the Pleistocene in South America.

Castoraeschna corbeti sp. nov. is described and diagnosed based on four males (holotype: Brazil, Para State, Floresta Nacional cle Carajas [6 degrees 06`13.9 `` S, 50 degrees 08`13.1 `` W, ca 600 m a.s.l.], 28 ix 2007 to be deposited in Museu Nacional, Universidade Federal do Rio de Janeiro, Rio de Janeiro). This species is similar to C. longfieldae and C. coronata but can be distinguished mainly by the absence of medio-dorsal spots on S8; postero-dorsal spots on S8-9 very narrow; cerci external margin almost straight in lateral view, without a distinct angulation between stern and base of lamina; cerci apex blunt. The probable ultimate stadium larva is described based on two individuals, male and female, collected at the type locality. Adults were observed flying along margins of a small shaded second-order stream where the larvae were taken. The surrounding forest is under impact of iron ore extraction and will probably disappear in the next years.

A Gram-negative, rod-shaped, non-spore-forming and nitrogen-fixing bacterium, designated ICB 89(T), was isolated from stems of a Brazilian sugar cane variety widely used in organic farming. 16S rRNA gene sequence analysis revealed that strain ICB 89(T) belonged to the genus Stenotrophomonas and was most closely related to Stenotrophomonas maltophilia LMG 958(T), Stenotrophomonas rhizophila LMG 22075(T), Stenotrophomonas nitritireducens L2(T), [Pseudomonas] geniculata ATCC 19374(T), [Pseudomonas] hibiscicola ATCC 19867(T) and [Pseudomonas] beteli ATCC 19861(T). DNA-DNA hybridization together with chemotaxonomic data and biochemical characteristics allowed the differentiation of strain ICB 89(T) from its nearest phylogenetic neighbours. Therefore, strain ICB 89(T) represents a novel species, for which the name Stenotrophomonas pavanii sp. nov. is proposed. The type strain is ICB 89(T) (=CBMAI 564(T) =LMG 25348(T)).

The ccpA gene was inactivated in the polyhydroxybutyrate (PHB)-producing strain Bacillus sp. MA3.3 in order to reduce glucose catabolite repression over pentoses and develop improved bacterial strains for the production of PHB from lignocellulosic hydrolysates. Mutant Bacillus sp. MSL7 Delta CcpA are unable to grow on glucose and ammonia as sole carbon and nitrogen sources, respectively. Supplementation of glutamate as the nitrogen source or the substitution of the carbon source by xylose allowed the mutant to partially recover its growth performance. RT-PCR showed that CcpA stimulates the expression of the operon (gltAB), responsible for ammonia assimilation via glutamate in Bacillus sp. MA3.3. Moreover, it was demonstrated that the supplementation of xylose or glutamate was capable of stimulating gltAB operon expression independently of CcpA. In PHB production experiments in mineral media, it has been observed that the glucose catabolite repression over the pentoses was partially released in MSL7. Although the carbohydrate consumption is faster in the ccpA mutant, the biomass and PHB biosynthesis are lower, even with supplementation of glutamate. This is attributed to an increase of acetyl-CoA flux towards the tricarboxylic acid cycle observed in the mutant. Copyright (C) 2011 S. Karger AG, Basel

Acanthamoeba spp., known to cause keratitis and granulomatous encephalitis in humans, are frequently isolated from a variety of water sources. Here we report for the first time the characterization of an Acanthamoeba sp. (ACC01) isolated from tap water in Brazil. This organism is currently being maintained in an axenic growth medium. Phylogenetic analysis based on SSU rRNA gene sequences positioned the new isolate in genotype T4, closest to the keratitis-causing isolate, A. polyphaga ATCC 30461 (similar to 99% similarity). Acanthamoeba ACC01 and A. polyphaga 30461 both grew at 37 degrees C and were osmotically resistant, multiplying in hyperosmolar medium. Both isolates secreted comparable amounts of proteolytic enzymes, including serine peptidases that were optimally active at a near neutral/alkaline pH and resolved identically in gelatin gels. Incubation of gels at pH 4.0 with 2 mM DTT also indicated the secretion of similar cysteine peptidases. Altogether, the results point to the pathogenic potential of Acanthamoeba ACC01.

Here, we described the expression and characterization of the recombinant toxin LTx2, which was previously isolated from the venomous cDNA library of a Brazilian spider, Lasiodora sp. (Mygalomorphae, Theraphosidae). The recombinant toxin found in the soluble and insoluble fractions was purified by reverse phase high-performance liquid chromatography (HPLC). Ca2+ imaging analysis revealed that the recombinant LTx2 acts on calcium channels of BC3H1 cells, blocking L-type calcium channels. (C) 2008 Elsevier Inc. All rights reserved.

Glyptodon sp. fossil remains can be found throughout Brazil. However, little information is available about their chronological distribution. With the intention to contribute to this issue, we present, as far as we know, the first direct radiocarbon date for 1 specimen of this genus found in Brazil. The osteoderm MZSP-PV660 found in Abismo do Fossil Cave (SP-145), Iporanga, Sao Paulo, Brazil, was dated by accelerator mass spectrometry at the Beta Analytic Radiocarbon Dating Laboratory. The (14)C date obtained was between 20,680 and 21,370 calibrated years before the present. Unfortunately, the scant (and often imprecise or unreliable) chronological data regarding this species and genus in Brazil and elsewhere in South America precludes a robust comparison among the dates available and the one presented here. Nevertheless, our finding supports the existence of this genus in South America at least until the Last Glacial Maximum.
