Background In Brazil, schistosomiasis mansoni infection is an endemic disease that mainly affects the country’s rural populations who carry out domestic and social activities in rivers and water accumulations that provide shelter for the snails of the disease. The process of rural migration to urban centers and the disorderly occupation of natural environments by these populations from endemic areas have favored expansion of schistosomiasis to locations that had been considered to be disease-free. Based on environmental changes that have occurred in consequent to an occupation and urbanization process in the locality of Porto de Galinhas, the present study sought to identify the relationship between those chances, measure by remote-sensing techniques, and establish a new endemic area for schistosomiasis on the coast of Pernambuco State - Brazil. Methods To gather prevalence data, two parasitological census surveys were conducted (2000 and 2010) using the Kato-Katz technique. Two malacological surveys were also conducted in the same years in order to define the density and infection rate of the intermediate host. Based on these data, spatial analyses were done, resulting in maps of the risk of disease transmission. To ascertain the environmental changes that have occurred at the locality, images from the QuickBird satellite were analyzed, thus resulting in land use maps. Results Over this 10-year period, the foci of schistosomiasis became more concentrated in the Salinas district. This area was considered to be at the greatest risk of schistosomiasis transmission and had the highest prevalence rates over this period. The study illustrated that this was the area most affected by the environmental changes resulting from the disorderly urbanization process, which gave rise to unsanitary environments that favored the establishment and maintenance of foci of schistosomiasis transmission, thereby consolidating the process of expansion and endemization of this

Background Manson’s schistosomiasis continues to be a severe public health problem in Brazil, where thousands of people live under the risk of contracting this parasitosis. In the Northeast of Brazil, schistosomiasis has expanded from rural areas to the coast of Pernambuco State, where the intermediate host is Biomphalaria glabrata snails. This study aims at presenting situational analyses on schistosomiasis at the coastal locality of Porto de Galinhas, Pernambuco, Brazil, by determining the risk factors relating to its occurrence from the epidemiological and spatial perspectives. Methods In order to gather prevalence data, a parasitological census surveys were conducted in 2010 in the light of the Kato-Katz technique. Furthermore, malacological surveys were also conducted in the same years so as to define the density and infection rates of the intermediate host. Lastly, socioeconomic-behavioral survey was also conducted to determine the odds ratio for infection by Schistosoma mansoni. Based on these data, spatial analyses were done, resulting in maps of the risk of disease transmission. To predict the risk of schistosomiasis occurrence, a multivariate logistic regression was performed using R 2.13 software. Results Based on prevalence, malacological and socioeconomic-behavioural surveys, it was identified a prevalence of 15.7% in the investigated population (2,757 individuals). Due to the malacological survey, 36 breeding sites were identified, of which 11 were classified as foci of schistosomiasis transmission since they pointed out snails which were infected by Schistosoma mansoni. Overall, 11,012 snails (Biomphalaria glabrata) were collected. The multivariate regression model identified six explanatory variables of environmental, socioeconomic and demographic nature. Spatial sweep analysis by means of the Bernoulli method identified one statistically significant cluster in Salinas (RR = 2.2; p-value < 0.000), the district with the highest occurrence

Tropical reefs are used for intensive tourism in various parts of the world. However, few studies have investigated the effect of regular trampling on these fragile ecosystems. The aim of this study was to assess the effect of different conservation strategies (open access, partial protection, and total long-term closure) on intertidal reef tops in Porto de Galinhas and Tamandaré, Pernambuco State, Brazil. Analysis of the macrobenthic community was performed with photo transects and image analysis (CPCe). Twenty-seven transects were surveyed from January to August 2012, in intensively impacted (I) open-access sites, in partially protected (P) sites with occasional, illegal trampling, and in a permanently closed (C) site. In I sites, total live cover was half the cover found in adjacent P sites. The area of bare rock averaged 53.6 and 25.0 % in I and P sites, respectively. In the C site, the area of bare rock was only 19.8 %. In I and P sites, macroalgae ( Palisada perforata) were dominating, while in the C site, the zoanthid Zoanthus sociatus was most abundant. Shell-bearing vermetids ( Petaloconchus varians) and bivalves ( Isognomon bicolor) were more abundant at the C site, being possible bioindicators for areas with zero or little trampling. Twelve years of total closure produced near-pristine communities in the C site, dominated by zoanthids and fragile mollusks. This study showed that trampling has severe and long-lasting consequences for the structure of these ecosystems.

As an introduction to the problems in the industrial production of heavy water, the industrial plants in operation are briefly described, and the causes determining their evolution are discussed. The industrial methods studied in England, France, Germandy, Sweden, Switzerland, India, Egypt, Japan, and O.E.C.E. for the production of D/sub 2/O are summarized. The market for heavy water is discussed. The factors considered in the selection of the production process to be developed for Argentina are given, and the cost of a H/sub 2/S-- H/sub 2/O exchange installation is determined. The cost of such a plant modified for Argentine needs ismore » then analyzed. It is concluded that the combination of the H/ sub 2/SH/sub 2/O process in a single unit with integral energy supply, coupled with the elimination of auxiliary installations, results in a considerable reduction in operation costs and plant investment, as compared with the cost of the process in the U.S. The plandt construction plan is summarized.

Zoonotic infectious diseases have been an important concern to humankind for more than 10,000 years. Today, approximately 75% of newly emerging infectious diseases (EIDs) are zoonoses that result from various anthropogenic, genetic, ecologic, socioeconomic, and climatic factors. These interrelated driving forces make it difficult to predict and to prevent zoonotic EIDs. Although significant improvements in environmental and medical surveillance, clinical diagnostic methods, and medical practices have been achieved in the recent years, zoonotic EIDs remain a major global concern, and such threats are expanding, especially in less developed regions. The current Ebola epidemic in West Africa is an extreme stark reminder of the role animal reservoirs play in public health and reinforces the urgent need for globally operationalizing a One Health approach. The complex nature of zoonotic diseases and the limited resources in developing countries are a reminder that the need for implementation of Global One Health in low-resource settings is crucial. The Veterinary Public Health and Biotechnology (VPH-Biotec) Global Consortium launched the International Congress on Pathogens at the Human-Animal Interface (ICOPHAI) in order to address important challenges and needs for capacity building. The inaugural ICOPHAI (Addis Ababa, Ethiopia, 2011) and the second congress (Porto de Galinhas, Brazil, 2013) were unique opportunities to share and discuss issues related to zoonotic infectious diseases worldwide. In addition to strong scientific reports in eight thematic areas that necessitate One Health implementation, the congress identified four key capacity-building needs: (1) development of adequate science-based risk management policies, (2) skilled-personnel capacity building, (3) accredited veterinary and public health diagnostic laboratories with a shared database, and (4) improved use of existing natural resources and implementation. The aim of this review is to highlight

The unusual occurrence of calcretes and prominent organic matter in the Middle Jurassic (Lower Bathonian, Serra de Aire Formation) of the Lusitanian Basin of western Portugal (Western Iberian Margin) revealed a complex palimpsest exposure record, here interpreted as reflecting hydrological changes caused by phases of emergence and immersion. It serves as a potential model for understanding stratigraphic development at lowstand surfaces in carbonate successions. The exposure-dominated facies association grades upwards into peritidal and lagoonal limestones, and the interval is assigned to the regressive peak of a Transgressive-Regressive Facies Cycle (2nd order) of the thick Middle Jurassic carbonate ramp succession. The Galinha Quarry, Fátima region, NE of Lisbon, a type section for this lowstand assemblage, exhibits varied calcretes, with black-clasts, interbedded with, and grading into: organic-rich marly/clayey seams and lenses, locally with carbonate nodules; carbonates with evaporite traces; microbial laminites; black-clast and fenestral limestones; some lithofacies are dolomitized. The palynofacies contains phytoclasts associated with less refractory, more prone to degradation components, which suggests natural combustion/pyrolysis (wild fires). The lowstand surface represents a low relief landscape with small depressions/ponds bordering a more distal marginal-littoral setting; the partly subaerial and partly subaqueous settings were subjected to lengthy exposure and to fluctuating, very shallow water bodies and water table. Coeval climatic regime was a seasonally dry/wet one, with dry/semi-arid phases dominating over the sub-humid, as shown by the combined record of intense calcrete development, rhizogenic structures, microbial mats, brecciation, desiccation, evaporites and wild fire evidence. However, sea level rise caused changes to shallow, sea-water influenced restricted lagoonal-peritidal settings. Comparisons and differences with modern and ancient

Introducción: en la actualidad existe un déficit en la evaluación de comedores dirigidos a niños menores de 3 años, a pesar de que se han realizado numerosas intervenciones en los comedores escolares con el fin de conseguir una alimentación segura y adecuada.Objetivo: realizar una evaluación nutricional de los menús ofertados en los centros de educación infantil de Sevilla.Material y métodos: se evaluó la frecuencia, variedad, rotación de alimentos, métodos culinarios e información de los menús de seis centros infantiles de Sevilla. Se valoró el aporte energético y nutricional mediante el programa Dietowin® y el método de pesada.Resultados: las frutas y verduras fueron deficitarias en la mayoría de los menús, y excesivas la carne, patatas, pasta y arroz. Se observó una escasa variedad de recetas por grupo de alimentos y no se daba una información completa del menú. Sin embargo, la variedad de procesos culinarios y la rotación de alimentos fueron adecuadas. Aunque la energía y el aporte de carbohidratos (~55%) se ajustaban a las necesidades, se observó un aporte excesivo de proteínas (~19%) y deficiente de lípidos (< 30%), sobre todo de grasas insaturadas. Respecto a los micronutrientes,solo vitamina C, E y calcio estaban por debajo de lo recomendado.Conclusiones: los centros de educación infantil están haciendo un gran esfuerzo por cumplir las recomendaciones nutricionales, pero todavía deben disminuir el aporte proteico y aumentar las grasas insaturadas de la dieta. Además, deben fomentar la oferta de frutas y verduras, ampliar la variedad de recetas, dar mayor información y disminuir el aporte de alimentos cárnicos.

ón potencial de esta especie. Utilizamos individuos recolectados de los bosques de pino implantados en la región centro oeste de la provincia de Córdoba (Argentina). La capacidad de dispersión de Arhopalus rusticus se determinó haciendo volar individuos recién emergidos en un molino de vuelo. Se registró el peso previo y posterior al vuelo, el largo del cuerpo y el tamaño del élitro. Las hembras fueron mejores voladoras, más largas, más pesadas, con élitros más largos que los machos. Observamos diferencias entre el potencial de dispersión dependiendo del estado de apareamiento de los individuos. Los individuos apareados volaron más rápido y mayores distancias que los individuos no apareados y consumieron una menor fracción de su peso corporal. Se observó una relación positiva entre el tamaño del élitro y la velocidad de vuelo. Se generó un mapa de las distancias de dispersión potencial de los machos y de las hembras para la región de estudio utilizando las distribuciones de las distancias obtenidas del molino de vuelo. La dispersión post copulación incrementa las chances de que la especie se establezca en zonas no ocupadas. © The Authors 2017.
