Abstract: A las ocho especies de poliplacóforos registradas en Bahía de la Paz, Baja California Sur, México, o cerca de ella, agregamos a Lepidochitona beanii, Chaetopleura lurida, Stenoplax limaciformis, S. mariposa, Lepidozona clathrata, L. serrata y Acanthochitona arragonites. El análisis de las comunidades estudiadas usando técnicas de ordenación sugiere que podría relacionarse la exposición al oleaje con la riqueza y la diversidad de especies. La comunidad recolectada en condiciones intermedias de exposición al oleaje presentó mayor número de especies y mayor diversidad de acuerdo con el índice de Shannon.

Abstract: RESUMEN Con este estudio se ha pretendido conseguir dos objetivos: el primero, indagar en los valores de eficacia en las microsituaciones de juego en desigualdad numérica temporal simple con o sin posesión del balón, y el segundo, analizar la relación entre los valores de eficacia en equipos con la condición de perdedor al finalizar el partido y en ambos sexos. Para la parte empírica se filmaron en vídeo todos los partidos de waterpolo del X Campeonato del Mundo celebrado en Barcelona durante el mes de Julio de 2003, para su posterior análisis consensuado entre dos especialistas previamente entrenados, siguiendo las directrices de la metodología observacional. Se valoró, mediante unos coeficientes, la eficacia en todas las microsituaciones de juego en desigualdad numérica temporal simple con o sin posesión del balón, obteniendo unos valores de eficacia. En la condición de perdedor al final del partido se revelaron diferencias entre ambos sexos en el coeficiente de exactitud de lanzamientos sin posesión (.008); tomando como referencia un valor de p<.05. Para concluir, afirmar que sólo en uno de los catorce coeficientes de eficacia propuestos para evaluar las microsituaciones de juego en desigualdad numérica temporal simple con o sin posesión del balón en waterpolo existen diferencias significativas entre sexos en equipos con la condición de perdedor al finalizar el partido. Palabras clave: waterpolo, eficacia, perdedor, desigualdad numérica temporal simple. ABSTRACT With this study has intended to obtain two objectives: the first one, to investigate the efficacy values in the playing microsituations in simple temporary numerical inequality with or without ball possession, and the second, to analyze the relation between these and the condition of loser at the end of the match and in both sexes. For the empirical part were recorded in video all the matches of the X Water polo World Championship celebrated in Barcelona during the month of July of 2003, for its subsequent analysis arrived at by consensus between two specialists previously coached, continuing the guidelines of the observational methodology. Valued themselves, by means of some coefficients, the efficacy in all the playing microsituations in simple temporary numerical inequality with or without ball possession obtaining some efficacy values. In the condition of loser at the end of the match differences were revealed among both sexes in the coefficient of shots exactness without possession (.008); taking as reference a value of p <.05. To conclude, to affirm that in one of the fourteen coeff

Abstract: kikuchi-fujimoto disease or necrotizing histiocytic lymphadenitis is a self-limited process of lymphatic system that affects more frequently young women. fever and adenopathy, often cervical, are typical. diagnosis is fundamentally based on the affected lymph node biopsy, since laboratory data are often normal. it's a very rare entity in spain, being more frequent in oriental countries. it's a benign evolution process, with a spontaneous healing in some weeks or months. this is the reason because of this disease could be infradiagnosed. it's very important the differential diagnosis with malignant lymphomas, because kikuchi-fujimoto disease doesn't need any treatment.
Influence of the Yesa reservoir on floods of the Aragón River, central Spanish Pyrenees
J. I. López-Moreno,S. Beguería,J. M. García-Ruiz
Hydrology and Earth System Sciences (HESS) & Discussions (HESSD) , 2002,
Abstract: The Yesa reservoir, the largest Pyrenean reservoir, was constructed in 1959 to supply water to new irrigated areas in the Ebro Depression, NE Spain. It is filled from October to May-June and then releases large quantities of water in the summer via the Bardenas Canal. The results confirm that the frequency of floods downstream of the dam decreased. The reduction mainly depends on two factors: i) the water storage level, and ii) the season of the year. Floods are very well controlled when the reservoir level is lower than 50%. Between 50 and 70%, only the highest floods are controlled. Finally, the reservoir retains mainly autumn and spring floods; most winter floods are released downstream to ensure the safety of the dam. Keywords: reservoir, flood control, flood seasonality, flood frequency, river regime, Pyrenees

Abstract: Los poliplacóforos asociados a los arrecifes de coral en la costa caribe a de Costa Rica han sido poco estudiados. El examen del cascajo de coral acumulado en el sublitoral somero, en cuatro estaciones de colección, localizadas en la Provincia de Limón reveló una diversidad de quitones mayor a la documentada. Anteriormente se habían registrado ocho especies para el Caribe costaricense: Ischnochiton erythronotus (C.B. Adams, 1845); Ischnoplax pectinata (Sowerby 1840); Stenoplax boogii (Haddon, 1886); S. purpurascens (C.B. Adams, 1845); Acanthopleura granulata (Gmelin, 1791); Chiton marmoratus Gmelin, 1791; C. tuberculatus Linnaeus, 1758; Acanthochitona rhodea (Pilsbry, 1893). Otras cinco se registran aquí por primera vez: Callistochiton portobelensis Ferreira 1976; Ischnochiton kaasi Ferreira 1987; I. pseudovirgatus Kaas 1972; Acanthochitona balesae Abbott 1954; Cryptoconchus floridanus (Dall 1889).

Abstract: Borna Disease Virus (BDV) causes a progressive non-suppurative meningoencephalitis that sometimes occurs in mortality; this disease has been reported for over two centuries ago in horses, sheep and cats in Central Europe and some regions of Asia. Currently, it is known that it causes neurological symptoms in various species of vertebrates including human beings. In Yucatan, Mexico, there is a single serological report about the circulation of BDV in schizophrenia patients; however, nothing is known about the circulation in animals. We obtained serum samples of 100 horses without apparent clinical signs caused by BDV infection, from various sites in the region. Antibodies against BDV were detected by electrochemiluminescence immunoassay (ECLIA) method with three recombinant proteins: BDV p24, BDV p40 and BDV p10 as antigens; obtaining a high seroprevalence of 44% (44/100). This study generates the first report of the probable activity of the BDV in healthy horses in Mexico and has expanded the infiltration area of BDV in the world. Nevertheless, several molecular investigations are required to detect BDV-RNA circulating and find sequences for clarification of the origin of BDV in Mexican horses.

Abstract: objective: because of the availability of a conjugate pneumococcal vaccine, the incidence and characteristics of invasive pneumococcal disease in children in the region of murcia should be determined. this would provide information that could be useful for properly establishing the indications for vaccination. methods: a retrospective search was conducted for cases of invasive streptococcus pneumoniae in children aged less 15 years old treated in hospitals in murcia from 1991-2000. the data sources were the databases of the microbiology services, the minimum data set, the pediatric admissions register and the edo register. results: the incidence rate for the period 1996-2000 was 18.25 per 105 children per year for children aged under 1 year in the case of invasive disease (10.6 for meningitis), 13.6 for those under 2 years for invasive disease (6 for meningitis), 8.9 for those under 5 years (1.35 for meningitis) and 3.7 for those under 15 years (1.3 for meningitis). twenty-eight percent of the patients presented risk factors. complications occurred in 35.2% and sequelae occurred in 5%. the mortality rate was 11.8%. the prevalent serogroups were 19, 6, 18, 5, 14 and 23. conclusions: the high percentage of patients with risk factors for invasive pneumococcal disease suggests the need to implement vaccination programs aimed at risk groups. although the incidence of invasive pneumococcal disease in the region of murcia differs from that in other areas, the incidence of meningitis is similar to that reported by other studies. because of the severity of the disease, cost-effectiveness studies to evaluate the possible incorporation of the vaccine in the vaccination calendar are justified.
