En Guatemala, para alcanzar los Objetivos de desarrollo del Milenio se implemen- tan Programas Conjuntos con el apoyo del Sistema de Naciones Unidas. Existen en la actualidad cinco Programas Conjuntos apoyando temas de seguridad alimen- taria, construcción de la paz, cambio climático, género y gobernabilidad económi- ca del agua. En el marco del programa conjunto: “Gobernabilidad económica en agua y sanea- miento” se decidió realizar un estudio que permitiera conocer la gobernabilidad en el sector a partir de hacer un inventario de las agrupaciones usuarias de agua con fines agrícolas y conocer algunas de sus características, este estudio contó con la asesoría técnica de la Organización de las Naciones Unidas para la Agricultura y la Alimentación –FAO– y el apoyo en campo de las comunidades asociadas por el agua y el medio ambiente de la cuenca del río Naranjo –CADISNA– en coordina- ción con el Ministerio de Agricultura Ganadería y Alimentación –MAGA– y go- biernos locales. El estudio se realizó en 8 municipios, 3 del departamento de Quetzaltenango y 5 de San Marcos, se identificaron 126 grupos de riego, de ellos, 73 pudieron ser carac- terizados. Se conoció que el 92% de los 73 grupos tiene una junta directiva que vela por el funcionamiento del sistema y la producción se ve diversificada en al menos 14 diferentes hortalizas siendo la principal el cultivo de la Papa. Sin embar- go sólo el 45% paga una tarifa a su grupo y el 60% de los usuarios necesita crédito para poder producir, haciendo uso de al menos 271.99 Lts/seg de agua para fines agrícolas. [less ▲]

As the inbred mouse strain SJL/J displays increased resistance to several pathogens and as its immune system shows multiple specificities, it is tempting to infer a causal link between these observations. The first question that comes to mind is whether adaptive immunity plays a role, and a way to answer this question is to see if the resistance phenotype persists when adaptive immunity is depressed. Although it has long been known that irradiation causes repression of leukopoiesis in mice, the technical data available in the literature are of no help in the case of strain SJL/J, because it displays exceptional radioresistance. Here we show that exposure of SJL/J to ∼9Gy, an intensity corresponding to the lethal dose 50 for the species Mus musculus, leads to serious but reversible alteration of leukopoiesis. This conclusion stems from an examination of the effects, 1-11 days post-exposure, of whole-body gamma-ray irradiation on leukocyte populations in the thymus and peripheral blood of young adult females. Immunodepression was most severe 4 days post-exposure. As in other strains, leukocyte populations displayed differential radiosensitivity, B (CD19(+)) cells being most sensitive, T (CD4(+)/CD8(+)) cells moderately sensitive, and natural killer (NK1.1(+)) cells most resistant. Surprisingly, however, the helper/inducer T lymphocytes proved more resistant than the cytotoxic/suppressor T lymphocytes, contrarily to what is observed in other strains. The procedure described will make it possible to refute or establish reliably the existence of causal links between SJL-specific phenotypic traits and immune aberrations and to elucidate further the respective roles of innate and acquired immunity in determining the resistance of this strain to an array of viral diseases.

Hyporheic exchange is an important process that underpins stream ecosystem function, and there have been numerous ways to characterize and quantify exchange flow rates and hyporheic zone size. The most common approach, using conservative stream tracer experiments and 1-D solute transport modeling, results in oversimplified representations of the system. Here we present a new approach to quantify hyporheic exchange and the size of the hyporheic zone (HZ) using high-resolution temperature measurements and a coupled 1-D transient storage and energy balance model to simulate in-stream water temperatures. Distributed temperature sensing was used to observe in-stream water temperatures with a spatial and temporal resolution of 2 and 3 min, respectively. The hyporheic exchange coefficient (which describes the rate of exchange) and the volume of the HZ were determined to range between 0 and 2.7 × 10−3 s−1 and 0 and 0.032 m3 m−1, respectively, at a spatial resolution of 1–10 m, by simulating a time series of in-stream water temperatures along a 565 m long stretch of a small first-order stream in central Luxembourg. As opposed to conventional stream tracer tests, two advantages of this approach are that exchange parameters can be determined for any stream segment over which data have been collected and that the depth of the HZ can be estimated as well. Although the presented method was tested on a small stream, it has potential for any stream where rapid (in regard to time) temperature change of a few degrees can be obtained. [less ▲]

Radiation hazard for space missions is mainly due to cosmic ray protons, helium nuclei and light ions, whose energy spectrum is maximum around 1 GeV per nucleon but remains non-negligible for energies up to 15 GeV per nucleon. Nuclear reactions induced by high energy protons are often described by intranuclear cascade plus evaporation models. The attention is focused here on the Liège Intranuclear Cascade model (INCL), which has been shown to reproduce fairly well a great deal of experimental data for nucleon-induced reactions in the 200 MeV to 2 GeV range, when coupled with the ABLA evaporation-fission code. In order to extend the model to other conditions relevant for space radiation, three improvements of INCL are under development. They are reported on here. First, the reaction model has been extended to nucleon-nucleus reactions at incident energies up to 15 GeV, mainly by the inclusion of additional pion production channels in nucleon-nucleon collisions during the cascade. Second, a coalescence mechanism for the emission of light charged particles has been implemented recently. Finally, the model has been modified in order to accommodate light ions as projectiles. First results are shown and compared with illustrative experimental data. Implications for issues concerning radiation protection in space are discussed. [less ▲]

Two types of nucleolus can be distinguished among eukaryotic cells: a tri-compartmentalized nucleolus in amniotes and a bi-compartmentalized nucleolus in all the others. However, though the nucleolus' ultrastructure is well characterized in mammals and birds, it has been so far much less studied in reptiles. In this work, we examined the ultrastructural organization of the nucleolus in various tissues from different reptilian species (three turtles, three lizards, two crocodiles, and three snakes). Using cytochemical and immunocytological methods, we showed that in reptiles both types of nucleolus are present: a bi-compartmentalized nucleolus in turtles and a tri-compartmentalized nucleolus in the other species examined in this study. Furthermore, in a given species, the same type of nucleolus is present in all the tissues, however, the importance and the repartition of those nucleolar components could vary from one tissue to another. We also reveal that, contrary to the mammalian nucleolus, the reptilian fibrillar centers contain small clumps of condensed chromatin and that their surrounding dense fibrillar component is thicker. Finally, we also report that Cajal bodies are detected in reptiles. Altogether, we believe that these results have profound evolutionarily implications since they indicate that the point of transition between bipartite and tripartite nucleoli lies at the emergence of the amniotes within the class Reptilia.

Pancreas preservation by cold storage using University of Wisconsin solution was the <br />mainstay method used for pancreas transplantation during the past 2 decades. Other <br />solutions, such as HTK, Celsior, and SCOT 15, could not demonstrate any advantage for <br />short preservation periods. But the advent of clinical islet transplantation and the larger <br />use of controlled non–heart-beating donors have prompted the transplantation community <br />to develop methods for increasing pancreas graft quality while preventing ischemic <br />reperfusion damages. Oxygenation by 1- or 2-layer methods during pancreas preservation, <br />as well as the use of perfluorocarbons, might increase the islet yield. Based on the former <br />methods, there is a renewed interest in machine perfusion and oxygenation in pancreas <br />preservation for pancreas transplantation and islet preparation. [less ▲]
