Annotated list of the Phlebotominae (Diptera) of Suriname

Phlebotomine sandflies were collected between 1952 and 1984 at 30 localities in the tropical rainforest and savanna regions of Suriname. Thirty-nine species were identified in the collections (2 Brumptomyia, 37 lutzomyia), including two known vectors of cutaneous leishmaniasis, Lutzomyia flaviscutellata and L. umbratilis. Nineteen of the species are new records for Suriname. In the rainforest region, the commonest phlebotomines were L. squatniventris maripaensis (79.8%), L. umbratilis (8.4%) and L. flaviscutellata (6.3%) in human bait catches, L. umbratilis (26.2%), L. infraspinosa (23.9%) and L. trichopyga (8.3%) in CDC light traps and L. umbratilis (84.3%), L. whitmani (6.8%) and L. shannoni (4.3%) in collections from tree trunks. The mean incidence of cutaneous leishmaniasis from 1979-1985 was 4.9 per 1000 inhabitants for the rainforest region and 0.66 per 1000 for Surinameas a whole.

Modelo de red de interconexión basado en enlace

La computación de altas prestaciones es una área de la informática que evoluciona rápidamente, en la que actualmente aparecen nuevos computadores que llegan a los petaflops. Al principio del trabajo, se estudian los distintos tipos de redes de interconexión y los modelos de red que se utilizan para medir su latencia. El objetivo de este trabajo, es el diseño, implementación y simulación de un modelo de red de interconexión basado en enlace, que tiene en cuenta la información de topología y enrutamiento de la red de interconexión. Teniendo en cuenta que los modelos son una abstracción del sistema, en éste trabajo se hace la verificación y validación del modelo, para asegurar que éste se aproxima a lo planteado en el diseño y también que se parece al sistema que se quiere modelar.

Voces del pasado, ecos del presente. la Red de Trabajo Contra la Violencia Sobre las Mujeres en Tiempos de Guerra y su labor en la sociedad japonesa

Gracias al trabajo de las redes transnacionales de defensa los marcos legales internacionales se han adaptado a las nuevas dimensiones que han alcanzado los conflictos armados en los últimos veinte años. Esta investigación estudia el papel de la Violence Against Women in War Network, Japan y del Women's Active Museum on War and Peace, como ejemplos de cómo los actores no gubernamentales pueden sensibilizar y transformar las normas nacionales e internacionales, el comportamiento de los Estados, los organismos supraestatales y a la sociedad en la que desarrollan su labor

La red literaria de París no se acaba nunca de Enrique Vila-Matas: un acto de lectura e interpretación

Este trabajo pretende realizar un acto de lectura e interpretación del texto de Enrique Vila-Matas París no se acaba nunca (2003). La lectura se sitúa desde la perspectiva concreta y delimitada de la red literaria que se teje en el novela. La metáfora de la red, atendiendo a sus tres acepciones: red como tejido, red como ardid y red como conexión, da las directrices del trabajo que intenta responder a estas cuestiones: a) qué hilos forman su tejido narrativo, b) cómo se configura la red, c) qué posibles mecanismos establecen la red como conexión. La lectura se inscribe en el doble marco de la intertextualidad y de la ironía. A través de las citas, alusiones y referencias literarias se destacan algunos procedimientos e intencionalidades en la configuración de la novelística de Enrique Vila-Matas, en su Manifiesto estético

Time and temperature dependant changes in red blood cell analytes used for testing recombinant erythropoietin abuse in sports.

There has been a long debate since the introduction of blood analysis prior to major sports events, to find out whether blood samples should be analysed right away on the site of competition or whether they should be transported and analysed in an anti-doping laboratory. Therefore, it was necessary to measure blood samples and compare the results obtained right after the blood withdrawal with those obtained after a few hours delay. Furthermore, it was interesting to determine the effect of temperature on the possible deterioration of red blood cell analytes used for testing recombinant erythropoietin abuse. Healthy volunteers were asked to give two blood samples and one of these was kept at room temperature whereas the second one was put into a refrigerator. On a regular basis, the samples were rolled for homogenisation and temperature stabilisation and were analysed with the same haematological apparatus. The results confirmed that blood controls prior to competition should be performed as soon as possible with standardised pre-analytical conditions to avoid too many variations notably on the haematocrit and the reticulocyte count. These recommendations should ideally also be applied to the all the blood controls compulsory for the medical follow up, otherwise unexplainable values could be misinterpreted and could for instance lead to a period of incapacity.

Analysis and clinical relevance of microparticles from red blood cells.

PURPOSE OF REVIEW: The mechanisms involved in the formation of red blood cell (RBC) microparticles in vivo as well as during erythrocyte storage are reviewed, and the potential role of microparticles in transfusion medicine is described. RECENT FINDINGS: Microparticles release is an integral part of the erythrocyte ageing process, preventing early removal of RBCs. Proteomics analyses have outlined the key role of band 3-ankyrin anchoring complex and the occurrence of selective RBC membrane remodelling mechanisms in microparticles formation. The presence of several RBC antigens, expressed on microparticles, has been demonstrated. The potential deleterious effects of RBC microparticles in transfused recipients, including hypercoagulability, microcirculation impairment and immunosuppression, are discussed. SUMMARY: Formation and role of RBC microparticles are far from being completely understood. Combining various approaches to elucidate these mechanisms could improve blood product quality and transfusion safety. Implementation of RBC microparticles as biomarkers in the laboratory routine needs to overcome technical barriers involved in their analysis.

Characterization of pupil responses to blue and red light stimuli in autosomal dominant retinitis pigmentosa due to NR2E3 mutation.

PURPOSE: We characterized the pupil responses that reflect rod, cone, and melanopsin function in a genetically homogeneous cohort of patients with autosomal dominant retinitis pigmentosa (adRP). METHODS: Nine patients with Gly56Arg mutation of the NR2E3 gene and 12 control subjects were studied. Pupil and subjective visual responses to red and blue light flashes over a 7 log-unit range of intensities were recorded under dark and light adaptation. The pupil responses were plotted against stimulus intensity to obtain red-light and blue-light response curves. RESULTS: In the dark-adapted blue-light stimulus condition, patients showed significantly higher threshold intensities for visual perception and for a pupil response compared to controls (P = 0.02 and P = 0.006, respectively). The rod-dependent, blue-light pupil responses decreased with disease progression. In contrast, the cone-dependent pupil responses (light-adapted red-light stimulus condition) did not differ between patients and controls. The difference in the retinal sensitivity to blue and red stimuli was the most sensitive parameter to detect photoreceptor dysfunction. Unexpectedly, the melanopsin-mediated pupil response was decreased in patients (P = 0.02). CONCLUSIONS: Pupil responses of patients with NR2E3-associated adRP demonstrated reduced retinal sensitivity to dim blue light under dark adaptation, presumably reflecting decreased rod function. Rod-dependent pupil responses were quantifiable in all patients, including those with non-recordable scotopic electroretinogram, and correlated with the extent of clinical disease. Thus, the chromatic pupil light reflex can be used to monitor photoreceptor degeneration over a larger range of disease progression compared to standard electrophysiology.
