Abstract: To address current challenges regarding sustainable development of wastewater treatment and provide scientific support in decision procedures towards sustainable solutions, new approaches, frameworks and methodologies about different possible solutions and their potential sustainability implications are needed. One way to facilitate sustainability assessment of wastewater is Life Cycle Assessment (LCA) methodology; however, it fails to map the full scope of wastewater impacts. This paper presents a framework to evaluate the performance of Wastewater Treatment Facilities (WWTF) taking into consideration various factors for insuring environmental sustainability. A total of nine indicators, seven environmental and two economic related to four wastewater treatment facilities, were assessed. Apart from evaluating the sustainability, this study also discussed the link of life cycle approach and social aspects of wastewater. The results show that for the environmental dimension using LCA provides information on different types of environmental activities and different impact categories. LCA can thus be used to quantify and compare the multiple types of impacts caused by one type of use or emission, as well as the various resource uses or emissions that contribute to one type of impacts. For the economic dimension, there is still a need for consistent and robust indicators and methods. The empirical results suggest that the environmental sustainability framework can be used in the first phase of the decision procedure that leads to a strategic choice for sustainable resource recovery from wastewater in developing countries. This motives researchers and decision-makers to consider the whole picture, and not just individual aspects, when considering different futures scenarios.

Abstract: Assemblages associated with intertidal rocky shores were examined for large scale distribution patterns with specific emphasis on identifying latitudinal trends of species richness and taxonomic distinctiveness. Seventy-two sites distributed around the globe were evaluated following the standardized sampling protocol of the Census of Marine Life NaGISA project (www.nagisa.coml.org). There were no clear patterns of standardized estimators of species richness along latitudinal gradients or among Large Marine Ecosystems (LMEs); however, a strong latitudinal gradient in taxonomic composition (i.e., proportion of different taxonomic groups in a given sample) was observed. Environmental variables related to natural influences were strongly related to the distribution patterns of the assemblages on the LME scale, particularly photoperiod, sea surface temperature (SST) and rainfall. In contrast, no environmental variables directly associated with human influences (with the exception of the inorganic pollution index) were related to assemblage patterns among LMEs. Correlations of the natural assemblages with either latitudinal gradients or environmental variables were equally strong suggesting that neither neutral models nor models based solely on environmental variables sufficiently explain spatial variation of these assemblages at a global scale. Despite the data shortcomings in this study (e.g., unbalanced sample distribution), we show the importance of generating biological global databases for the use in large-scale diversity comparisons of rocky intertidal assemblages to stimulate continued sampling and analyses.

Abstract: El objetivo del presente estudio fue evaluar el efecto de los anticuerpos presentes en la sangre de Bos taurus inmunizado con antígenos ocultos del intestino de Stomoxys calcitrans sobre la supervivencia de las moscas adultas y sobre la oviposición. Se obtuvieron cinco mil intestinos de S. calcitrans alimentadas con sangre normal de bovino, para preparar un extracto antigénico (AgIn-Sc). Posteriormente, un bovino fue inmunizado con AgIn-Sc en adyuvante incompleto de Freund los días 0, 14, 21, 28, 35 y 40. Otro bovino (testigo) fue inoculado con solución salina en las mismas fechas. A los días 40 y 50 posinmunización se recolectó sangre periférica de los dos animales; una parte se utilizó para obtener suero, que se congeló en alícuotas a 70oC hasta su uso, y la otra se conservó en citrato de sodio al 2% a 4oC. Con esta última se alimentó durante una semana a grupos de 200 moscas S. calcitrans recién emergidas/bovino, las cuales se mantuvieron bajo condiciones de laboratorio. Durante los días 40 y 50 posinmunización se practicaron tres observaciones diarias durante una semana para evaluar la mortalidad de las moscas y contar el número de huevos depositados (HD). Se observó que no hubo un efecto da ino de la sangre del animal inmunizado sobre la supervivencia de las moscas, pero sí sobre la oviposición. Se apreció una disminución signifi cativa en el número total de HD, que osciló entre 29% (P < 0.05, sangre del día 40) y 65% (P < 0.01, sangre del día 50) con respecto al número de HD por las moscas que se alimentaron de sangre del animal testigo. Mediante ELISA se obtuvieron los títulos de anticuerpos IgG antiintestino en el suero del animal inmunizado: 1:1280 y 1:2560 para los días 40 y 50, respectivamente; mientras que en los mismos días, el suero del bovino testigo fue negativo a dichos anticuerpos. Por Western blot, el suero del día 50 reconoció siete componentes en el AgIn- Sc con pesos moleculares aparentes que oscilaron entre 35 y 205 kilodaltones. Con base en estos resultados se concluye que el procedimiento de inmunización utilizado indujo la formación de anticuerpos IgG antiintestino, que no afectaron la supervivencia de la mosca, pero sí su oviposición.

Abstract: Visceral leishmaniasis (VL) in Latin America and particularly in Venezuela, is a protozoan infection that in recent decades has shown changes in the epidemiological pattern, initially rural to activating urban foci, resulting in the emergence of a public health problem in the periphery of large cities. In the Parasitology Department, Carabobo University, in 2005, was diagnosed a case of human visceral leishmaniasis in a 2-year old child, resident of Barrio Los Próceres, located in the Municipality Naguanagua, Carabobo State. This was the first reported case of VL in this community. From this finding we carried out a seroepidemiological study in human and canine population of this community in an attempt to characterize it as an urban focus of VL. An epidemiological survey was conducted and blood samples were taken from the human and canine population living in an area of 200 m. of the index case, in order to detect anti-leishmania antibodies using the ELISA-rK39 test. The seroprevalence obtained for human was 5.96% (9 / 151), and for dogs 24.24% (8 / 33). 55.55% of seropositive humans were between 0-13 years old. No evidence of association between seropositivity and assessed epidemiological variables such as educational level, occupation, length of residence in the town of origin, from other communities and the presence of dogs. Most of the seropositive dogs were over 2 years of age and in an asymptomatic condition. Results suggest the presence of a new recent focus of urban LV of in the studied area

Abstract: leptospirosis is a zoonosis disseminated around the world, affecting about 160 wild and domestic species, which are latent reservoirs and a main source of contamination for humans. this zoonosis is caused by leptospira sp., gram-negative bacteria have the ability to survive in the urine. in addition, the impact in public health is given for the presence of puddles, ponds and standing water that are easily contaminated and that is become a permanent focus of transmission. leptospirosis is diagnosed by using the conventional technique microglutinacion (mat). however, there are no standardized criteria of titles considered positive, resulting in a significant number of positives and negatives false. therefore, it is necessary to evaluate new diagnostic strategies highly sensitive and specific to achieve a reliable and accurate diagnosis. this article seeks to review the role of proteins associated with pathogenicity and utility of gene expression studies in the implementation of new diagnostic techniques that allow postulating molecular markers of infection

Abstract: Objetive: To evaluate, in nine long distance runners, the effects of dehydration during a submaximal (80% of the maximal physical work capacity -PWCmax-) and prolonged exercise (90 minutes), on serum concentration of lactate and its relation with cortisol and glucose. Methods: After a ten-minute warm-up on a treadmill, 1% grade and at 55% of PWCmax, followed by 90 min test in six stages, at 80% of PWCmax, there was a final 90 min passive recovery period. No water was replenished during the DH procedure (dehydration); during the RH procedure (rehydration) 51% of the body weight lost during the DH procedure was replaced. Results: In dehydrated runners increments were observed, with respect to the basal values, in lactate serum concentration, at the end of the exercise (minute 90); in plasmatic cortisol concentration at the end of the exercise (minutes 75 and 90) and in the first hour of the recovery period; and in glucose plasmatic concentration throughout the procedure. With partial water replenishment lactate increment became significant during almost all stages of the exercise; cortisol increment was avoided; glucose increment was lower during the exercise and avoided during recovery. Conclusion: During a submaximal and prolonged exercise performed by long distance runners, under Objetivo: establecer, en nueve atletas corredores de fondo, los efectos de la deshidratación, durante la realización de un ejercicio submáximo, al 80% de la capacidad física máxima de trabajo (PWCmax), de larga duración, 90 minutos, sobre la concentración sérica del lactato, y la relación de éste con el cortisol y la glucosa. Método: después de diez minutos de calentamiento en banda rodante, con una pendiente del 1% y al 55% de la PWCmax, siguieron 90 minutos de carrera, en seis intervalos, al 80% de la PWCmax; finalmente, 90 minutos de recuperación pasiva. No se hizo reposición hídrica durante el procedimiento DH (deshidratado); durante RH (rehidratado) se repuso el 51% del peso corporal perdido en DH. Resultados: en individuos deshidratados se observaron, con respecto al valor basal, incrementos en la concentración sérica del lactato, al final del ejercicio (minuto 90); en la concentración plasmática del cortisol, al final del ejercicio (minutos 75 circuy 90) y en la primera hora de la recuperación; en la concentración plasmática de la glucosa, durante todo el procedimiento. Con la reposición parcial de las pérdidas hídricas el incremento del lactato se hizo significativo durante casi todas las etapas del ejercicio; se evitó el del cortisol; el de la glucosa fue menor durant
