    The combined analysis of (222)Rn activity concentrations and mesoscale meteorological conditions at Huelva city (Spain) was addressed in this study to understand the potential impact of phosphogypsum piles on the (222)Rn activity concentrations registered at this area. Hourly mean data from April 2012 to February 2013 registered at two sampling sites (Huelva city and in the background station of El Arenosillo, located 27 km to the south-east) have been used in the study. The results of the present study showed a large difference in mean radon concentrations between the two stations during the sampling period, 6.3 ± 0.4 Bq m(-3) at Huelva and 3.0 ± 0.2 Bq m(-3) at El Arenosillo. The analysis has demonstrated that hourly (222)Rn concentrations at Huelva city above 22 Bq m(-3), with nocturnal peaks up to 50 Bq/m(3), mainly coincided with the occurrence of a pure sea-land breeze cycle. Mesoscale circulations in this region are mainly characterized by two patterns of sea-land breeze, pure and non-pure, with the phosphosypsum piles directly upstream (south) of the city during the afternoon on pure sea-breeze days. The difference between mean (222)Rn activity concentrations at Huelva city were 9.9 ± 1.5 Bq m(-3) for the pure pattern and 3.3 ± 0.5 Bq m(-3) for the non-pure pattern, while in the background station concentrations were 3.9 ± 0.4 Bq m(-3) and 2.8 ± 0.4 Bq m(-3) respectively. Considering these large differences, a detailed analysis of composites and case studies of representative sea-land breeze cycles of both types and their impact on (222)Rn activity concentration was performed. The results suggested that the presence of the phosphogypsum piles was necessary in order to justify the high (222)Rn activity concentrations observed at Huelva compared with the background station in the afternoons on pure sea breeze days (1.5-2.0 Bq m(-3)). On the other hand, large night time differences between the two sites on these days were

    This is the first report of ostreid herpesvirus 1 microvariant (OsHV-1 µVar) infecting natural oyster beds located in Huelva (SW Spain). The virus was detected in 3 oyster species present in the intertidal zone: Crassostrea gigas (Thunberg, 1793), C. angulata (Lamarck, 1819) and, for the first time, in Ostrea stentina Payraudeau, 1826. Oysters were identified by a specific polymerase chain reaction (PCR) and posterior restriction fragment length polymorphism (RFLP) analysis based on cytochrome oxidase I (COI) mitochondrial DNA. Results confirmed that C. angulata still remains the dominant oyster population in SW Spain despite the introduction of C. gigas for cultivation in the late 1970s, and its subsequent naturalization. C. angulata shows a higher haplotype diversity than C. gigas. OsHV-1 virus was detected by PCR with C2/C6 pair primers. Posterior RFLP analyses with the restriction enzyme MfeI were done in order to reveal the OsHV-1 µVar. Detections were confirmed by DNA sequencing, and infections were evidenced by in situ hybridization in C. gigas, C. angulata and O. stentina samples. The prevalence was similar among the 3 oyster species but varied between sampling locations, being higher in areas with greater harvesting activities. OsHV-1 µVar accounted for 93% of all OsHV-1 detected.

    Trace elements may present an environmental hazard in the vicinity of mining and smelting activities. However, the factors controlling trace element distribution in soils around ancient and modern mining and smelting areas are not always clear. Tharsis, Riotinto and Huelva are located in the Iberian Pyrite Belt in SW Spain. Tharsis and Riotinto mines have been exploited since 2500 B.C., with intensive smelting taking place. Huelva, established in 1970 and using the Flash Furnace Outokumpu process, is currently one of the largest smelter in the world. Pyrite and chalcopyrite ore have been intensively smelted for Cu. However, unusually for smelters and mines of a similar size, the elevated trace element concentrations in soils were found to be restricted to the immediate vicinity of the mines and smelters, being found up to a maximum of 2 km from the mines and smelters at Tharsis, Riotinto and Huelva. Trace element partitioning (over 2/3 of trace elements found in the residual immobile fraction of soils at Tharsis) and soil particles examination by SEM-EDX showed that trace elements were not adsorbed onto soil particles, but were included within the matrix of large trace element-rich Fe silicate slag particles (i.e. 1 mm o at least 1 wt.% As, Cu and Zn, and 2 wt.% Pb). Slag particle large size (1 mm o) was found to control the geographically restricted trace element distribution in soils at Tharsis, Riotinto and Huelva, since large heavy particles could not have been transported long distances. Distribution and partitioning indicated that impacts to the environment as a result of mining and smelting should remain minimal in the region.

    This paper deals with the mining of reworked gossan at Riotinto (Huelva, southwest Spain). The rock in question is a conglomerate formed by the erosion of gossan and its subsequent deposition in areas at some distance from its origin. In Roman times this mineral was used as construction material as well as for architectural decoration and possibly as an ore for making mining tools. This work focuses upon the exploitation of this mineral as an iron ore mined from the site known as Mesa Pinos or Alto de la Mesa by the Rio Tinto Company Ltd. between the last quarter of the 19th century and the first part of the 20th century.

  6. Impact of a 1755-like tsunami in Huelva, Spain

    Full Text Available Coastal areas are highly exposed to natural hazards associated with the sea. In all cases where there is historical evidence for devastating tsunamis, as is the case of the southern coasts of the Iberian Peninsula, there is a need for quantitative hazard tsunami assessment to support spatial planning. Also, local authorities must be able to act towards the population protection in a preemptive way, to inform "what to do" and "where to go" and in an alarm, to make people aware of the incoming danger. With this in mind, we investigated the inundation extent, run-up and water depths, of a 1755-like event on the region of Huelva, located on the Spanish southwestern coast, one of the regions that was affected in the past by several high energy events, as proved by historical documents and sedimentological data. Modelling was made with a slightly modified version of the COMCOT (Cornell Multi-grid Coupled Tsunami Model code. Sensitivity tests were performed for a single source in order to understand the relevance and influence of the source parameters in the inundation extent and the fundamental impact parameters. We show that a 1755-like event will have a dramatic impact in a large area close to Huelva inundating an area between 82 and 92 km2 and reaching maximum run-up around 5 m. In this sense our results show that small variations on the characteristics of the tsunami source are not too significant for the impact assessment. We show that the maximum flow depth and the maximum run-up increase with the average slip on the source, while the strike of the fault is not a critical factor as Huelva is significantly far away from the potential sources identified up to now. We also show that the maximum flow depth within the inundated area is very dependent on the tidal level, while maximum run-up is less affected, as a consequence of the complex morphology of the area.

    Major ions, nutrients, trace elements and pesticides distribution were studied in a coastal wetland heavily impacted by human development in Spain. Past land use has altered the local hydrodynamics leading to the partitioning of the ecosystem into a tideland subject to marine influence, and an artificial freshwater reservoir created by stream impoundment. The tideland stretch is flooded twice a day with a heavy metal plume that emerges from the mine-polluted estuary of Huelva and propagates landward depicting the same dispersal trend of major seawater ions. Additionally, the tidal channel receives acid discharges from industrial point sources that contribute to metal enhancement. The impounded area and stream tributaries are affected by agrochemicals runoff (nitrate, phosphate, pendimethalin, simazine, diuron and therbuthylazine) from surrounding agricultural lands. The tidal regime plays a crucial role in the transport and dispersion of pollutants, except in the artificial reservoir where freshwater exhibits a seasonal mineralization pattern.

  11. Mineralogy and origin of atmospheric particles in the industrial area of Huelva (SW Spain)

    The mineralogy of atmospheric particles at the confluence of the Tinto and Odiel rivers, south of Huelva (a highly industrialized city in the SW Spain), was characterized in view to identify source origins. In spite of the small amount of sample collected, mineralogical characterization was performed by X-ray diffraction, polarized light microscopy and scanning electron microscopy with EDS analysis system, using an adequate sample preparation methodology. Sedimentable (SP) and aerosols particles were sampled an one-week basis every two months for one year. Quartz, calcite and feldspars were found to be the major minerals in both fractions, and phyllosilicates, dolomite and gypsum were also identified in lower content. Minor mineral particles included barite, apatite, sphalerite and pyrite. SEM studies revealed the additional presence of chalcopyrite in both SP and aerosols, and of chalcocite-covellite, halite and sylvite in the latter. Siderite, hematite and ankerite were only detected in the SP fraction. The concentrations of the previous minerals increased in summer by effect of the limited rain and the resulting scarcity of atmosphere washing. Non-mineral particles detected by SEM in SP and aerosol fractions included spherical, biological and compositionally complex particles. The main source of mineral particles was found to be the soil suspension in addition to the metallurgical and fertilizer production industries in the area.

    Women seem more willing to donate blood than men despite the limitations that affect their donation rate. The aim of our study was to determine the role of women in altruistic donation of blood in Huelva, a province in south-western Spain. We registered 87,601 offers to donate whole blood between January 1st, 2005 and December 31st, 2009. We statistically analysed variables such as sex, age, offers, deferrals and donations, problems in venous access, vasovagal reactions, weight and blood pressure to establish their significance according to donor gender. With regards to gender, 52.3% of donors were women and 47.7% men. Of the 87,601 offers to donate blood, 46.5% were from females and 53.5% from males. More females than males made their first donation during the study period. However, 43.9 % of donations were from women, whereas 56.1% were from men. Overall 8.7% of offers were deferred, 62.7% of which due to a low haemoglobin concentration, which was the most frequent cause of deferral in women. Difficulties in venous access and vasovagal reactions were also more frequent in female donors than in male donors. By the end of the study period, donor fidelity was 58.6% for men and 48.6% for women. In the province of Huelva, women are more altruistically inclined than men to give blood, with the percentages of donors and first-time donors being higher among females. However, there are restrictions to women giving blood, especially low haemoglobin concentration, which reduce the number of female blood donations. Women also have more difficulty when blood is withdrawn and are more susceptible to vasovagal reactions, which negatively affect their experience as donors. Measures should be taken to reduce these barriers to encourage women to continue to offer to donate blood, thereby ensuring that they become regular donors, which is a key factor in guaranteeing an adequate supply of blood within the region of Andalusia.

    Relationship between toxicity and bioavailable metals in sediments from the Huelva estuary and its littoral of influence was analyzed. Toxicity was assessed with Microtox® bioassay using a marine luminescent bacterium: Vibrio fischeri. Bioavailable metals were considered as both, acid extractable fraction of BCR procedure and the sum of exchangeable and bound to carbonates fractions of Tessier sequential extraction. A bioavailable metals index was calculated to integrate results in a single figure. Toxicity and bioavailable metals showed a similar pattern. Higher levels were found in the estuary than in the littoral (140 TU/g). In Huelva estuary, highest levels were found in the Tinto estuary (5725 TU/g), followed by the Odiel estuary (5100 TU/g) and the Padre Santo Canal (2500 TU/g). Results in this area were well over than those in nearby estuaries. Furthermore, they are similar to or even higher than those in other polluted sediments around the world. Bioavailable metal index showed a stronger correlation with acid extractable fraction of BCR (R(2) = 0.704) than that for the sum of exchangeable and bound to carbonates fractions of Tessier (R(2) = 0.661). These results suggest that bioavailable metals are an important source of sediment toxicity in the Huelva estuary and its littoral of influence, an area with one of the highest mortality risks of Spain.

    The setting up of the Committee of Works of the Port of Huelva coincided with the revitalization of mining in the province during the last third of the 19th century, stimulated by the injection of the foreign capital and technology. The mining legislation concerning customs duties of 1868 also contributed to triggering mining fever. For its part, the Port of Huelva began its administrative development within a succession of norms by which other similar bodies were progressively created along the Spanish coasts, with the encouragement of the local middle-classes. Mineral ores began to emerge from the bowels of the earth in Huelva at the eager hands of the miners, especially copper, manganese and pyrites, which was transported by the railways to the Port of Huelva, from whence, thanks to the development of its infrastructure, they were subsequently exported, mainly to a Europe in the throes of its second industrial revolution.

    The Ria of Huelva (south-west Spain) is one of the most polluted fluvial-estuarine systems in the world. Industrial activity delivers huge amounts of pollutants to the local environment, particularly heavy metals and arsenic. Here we aimed to determine urinary levels of As, Cd, Cr, Cu and Ni in a representative sample (n=857) of adults living in the Ria of Huelva. Levels were compared to those from a representative sample of 861 adults of the general urban population of Andalusia (southern Spain) and multiple regression models were developed to identify individual factors associated with urinary levels of these elements. Arsenic levels were significantly higher in the Ria of Huelva as compared to other Andalusian cities, whereas Cd and Ni levels were significantly lower. Despite these differences, levels in both groups were similar to the reference values reported in previous studies for general population. Age, gender, diet and lifestyle were the major factors contributing to the interindividual variation in urinary metals. In conclusion, despite living in a highly polluted area, the population of the Ria of Huelva failed to show higher urinary levels of the studied metals as compared to a reference urban population of the same region.

    Photochemical ozone pollution of the lower troposphere (LT) is a very complex process involving meteorological, topographic emissions and chemical parameters. Ozone is considered the most important air pollutant in rural, suburban and industrial areas of many sites in the world since it strongly affects human health, vegetation and forest ecosystems, and its increase during the last decades has been significant. In addition, ozone is a greenhouse gas that contributes to climate change. For these reasons, it is necessary to carry out investigations that determine the behaviour of ozone at different locations. The aim of this work is to understand the levels and temporal variations of surface ozone in an industrial-urban region of the Southwest Iberian Peninsula. The study is based on ozone hourly data recorded during a 6-year period, 2000 to 2005 at four stations and meteorological data from a coastal station. The stations used were El Arenosillo and Cartaya--both coastal stations, Huelva--an urban site and Valverde--an inland station 50 km away from the coastline. The general characteristics of the ozone series, seasonal and daily ozone cycles as well as number of exceedances of the threshold established in the European Ozone Directive have been calculated and analysed. Analysis of the meteorological data shows that winter-autumn seasons are governed by the movement of synoptic weather systems; however, in the spring-summer seasons, both synoptic and mesoescale conditions exist. Average hourly ozone concentrations range from 78.5 +/- 0.1 microg m(-3) at Valverde to 57.8 +/- 0.2 microg m(-3) at Huelva. Ozone concentrations present a seasonal variability with higher values in summer months, while in wintertime, lower values are recorded. A seasonal daily evolution has also been found with minimum levels around 08:00 UTC, which occurs approximately 1-1.5 h after sunrise, whereas the maximum is reached at about 16:00 UTC. Furthermore, during summer, the maximum value

    The response of wild fish to heavy metals was studied in sole (Solea senegalensis) collected in 2004, 2005 and 2006 at three sampling sites from Huelva estuary (SW Spain), in the vicinity of a petrochemical and mining industry. Heavy metals As, Cd, Cu, Fe, Pb and Zn were analyzed in samples collected from sediment, water and tissue (liver) to examine their bioconcentration and effects in fish such as lipid peroxidation (LPO), catalase (CAT; EC 1.11.1.6), glutathione peroxidase (GPx; EC 1.8.1.7), glutathione S-transferase (GST; EC 2.5.1.18) and glutathione reductase (GR; EC 1.11.1.6) were also analyzed in the fish liver. The results showed different effects in sole from diverse locations with varying degrees of pollution. Significant differences in LPO, CAT and GR activities between control fish and fish from sampling sites were observed as well as seasonal differences for biomarkers. Significant correlations were established between some biomarkers and heavy metals concentrations in liver, sediment and water. This study indicates the usefulness of integrating a set of biomarkers to assess the effects of pollutants in aquatic environments under complex mix of pollutants and chronic pollution situation.

    We analyse in this paper a bowl fragment, probably Milesian, which comes from the excavations of Calle del Puerto, in the Tartessian settlement of Huelva. Along the outside lip runs an archaic Ionian inscription —middle of the 6th c. B .C.— whose interpretation is particularly difficult. It may be a dedication or offering made by a Greek for a local chief. But nothing can be said about it with certainty. | Se estudia en este artículo un fragmento de cuenco, probablemente milesio, que procede ...

    Huelva Estuary is a transition zone where REE-rich acidic waters interact with saline-alkaline seawater. This mixing process influences the geochemical and mineralogical characteristics of particulate and dissolved fractions. The Tinto River has >11,000μgL -1 dissolved REE (pH=1.66), whereas seawater only reaches 8.75·10 -2 μgL -1 dissolved REE (pH=7.87). REE-normalized patterns in "pH<6 solutions" are parallel and show similarities, diminishing their concentration as pH increases. Sequential extraction performed on the generated precipitates of mixed solutions indicates that most REE are associated to the residual phase. In a second order, REE are associated with soluble salts at pH3 and 3.5 whereas in sediments generated at pH4 and 5, they are distributed in salts (1° extraction), poorly crystallized Fe-bearing minerals (schwertmannite, 3° extraction) and well crystallized Fe-bearing minerals (goethite - hematite, 4° extraction). Finally, precipitated REE are highest at pH6 newly formed minerals with a release to solution in higher pH. Copyright © 2017 Elsevier Ltd. All rights reserved.

    The correct diagnosis of hypothyroidism during pregnancy requires knowledge of the local trimester-specific thyrotropin (TSH) reference ranges. When these are not available, the guidelines recommend upper limits of 2.5, 3.0, and 3.0μU/ml for the 1 st , 2 nd , and 3 rd trimesters, respectively. The aim is to establish the reference range for our local population. A population-based observational study was performed on healthy pregnant women from 11 healthcare centres in the province of Huelva. Women were recruited consecutively during 2016 through the pregnancy process. Women were excluded who had a history of thyroid or medical disease, a poor obstetric history, multiple pregnancy, thyroid autoimmunity, and extreme TSH values (10μU/ml), as well as women treated with levothyroxine for thyroid dysfunction. The study included a total of 186 pregnant women, with a mean age of 30.7 years (95% CI: 29.8-31.6) and a body mass index (BMI) of 23.6 (95% CI: 23.2-24.0). Most of them had the first laboratory tests performed before week 11 of pregnancy. Valid subjects for analysis were 145, 105, and 67 pregnant women in the 1 st , 2 nd , and 3 rd trimesters, respectively, after excluding those due to abortion (18.9%), autoimmunity (6.5%), hypo/hyperthyroidism (2.2%), and levothyroxine treatment during the 2 nd /3 rd trimester (18.6%). The 97.5% TSH percentile for the 1 st , 2 nd , and 3 rd trimester was 4.68, 4.83, and 4.57μU/ml, respectively. Thyroid dysfunction was identified in 80 women (55.2%), 33 of whom received treatment with Levothyroxine (22.7%). With the new criteria, thyroid dysfunction prevalence would be reduced to 6.2%, and the need for treatment to 4.1%. The reference range for TSH in our population differs from that proposed by the guidelines. Unnecessary treatment was being given to 18.6% of pregnant women.

    Full Text Available Uno de los nichos laborales en los que más fácilmente encuentran empleo los inmigrantes extranjeros es en la prostitución, sobre todo las mujeres. Estas nuevas trabajadoras se incorporan a todas las variantes que tiene el oficio, desde los clubs de alterne a la calle. La urgencia por conseguir el dinero necesario con el que subsistir o pagar las deudas contraídas para su viaje al «paraíso», una posible explotación sexual por las mafias, la dificultad para acceder a otros puestos de trabajo y los substanciosos ingresos que en ocasiones pueden conseguir explican esta situación. En esta comunicación se muestran las características sociodemográficas que presentan las mujeres que se dedican a esta actividad en la provincia de Huelva. Además se hace una exposición de los recursos existentes en este territorio para atender sus necesidades.

    Full Text Available In just two decades, the city of Huelva and its agro-industry belt has gone from being mainly farming spaces to become cities completely urbanized. Among other consequences, this population boom is due to the increase of the immigrant population, mostly from Europe’s East, North Africa and Latin America. Therefore, migration is a global phenomenon, but the current radical tendencies and the increase of racism threaten the peace of prosperous societies. The situation of young people regarding the migratory phenomenon notices their differences in the educational ambience across the factors that determine the social functioning. In this article appears empirical evidences of a quantitative research conducted in four centers of Obligatory Secondary Education with the aim of addressing the attitudes and the behaviors of the young people from Huelva regarding immigration. On these results is highlighted a marked pattern of otherness where half of the interrogated persons identifies East Europeans like «others». The same happens with the religion or the race, though in this case the vast majority refers to the Muslim religion or the black race, respectively. Nonetheless, the most relevant result appeared is that more than 40 % of the interrogated persons maintains the denial of the right of asylum or the reduction of other rights to the newcomers. So, despite being favorable to the immigration and having an intercultural point of view, the young people of Huelva, in certain contexts, suggest features or values that usually coincide with the rejection or even the racism.

    Metallurgic mine wastes often contain high concentrations of potentially toxic elements, the mobility of which may pose an environmental hazard for water and surrounding ecosystems. We have examined the mobility of Ag, As, Cu, Pb and Zn from composite surface samples (0-20 cm) of different pyritic tailings impoundments in the province of Huelva (Spain). These samples were also subject to physical chemical and mineralogical (XRD) characterization. The total metal content of the tailings ranged between 1.89-11.2 ppm for Ag, 72-610 ppm for As, 245-1194 ppm for Cu, 220-11933 for Pb and 41-706 for Zn, all proving to be highly acidic. The mobility of these elements was assessed by using a seven-step sequential extraction procedure and applying the toxicity characteristic leaching procedure (TCLP). We investigated the applicability of TCLP to the tailings by comparing the results with those of the first steps of the sequential extraction procedure. It was found that the pH values remained buffered (close to 4.97) upon adding the TCLP extraction reagent and that the pH values differed significantly from those of the aqueous extracts. This could result in an underestimation of mobile forms compared with those dissolved in water. We may also conclude that due to the presence of specific minerals or to the preference of some elements for acetate ions the results of any assessment of metal mobility in pyritic tailings using the TCLP test may be questionable.

    A detailed physical and chemical characterization of coarse particulate matter (PM10) and fine particulate matter (PM2.5) in the city of Huelva (in Southwestern Spain) was carried out during 2001 and 2002. To identify the major emission sources with a significant influence on PM10 and PM2.5, a methodology was developed based on the combination of: (1) real-time measurements of levels of PM10, PM2.5, and very fine particulate matter (PM1); (2) chemical characterization and source apportionment analysis of PM10 and PM2.5; and (3) intensive measurements in field campaigns to characterize the emission plumes of several point sources. Annual means of 37, 19, and 16 microg/m3 were obtained for the study period for PM10, PM2.5, and PM1, respectively. High PM episodes, characterized by a very fine grain size distribution, are frequently detected in Huelva mainly in the winter as the result of the impact of the industrial emission plumes on the city. Chemical analysis showed that PM at Huelva is characterized by high PO4(3-) and As levels, as expected from the industrial activities. Source apportionment analyses identified a crustal source (36% of PM10 and 31% of PM2.5); a traffic-related source (33% of PM10 and 29% of PM2.5), and a marine aerosol contribution (only in PM10, 4%). In addition, two industrial emission sources were identified in PM10 and PM2.5: (1) a petrochemical source, 13% in PM10 and 8% in PM2.5; and (2) a mixed metallurgical-phosphate source, which accounts for 11-12% of PM10 and PM2.5. In PM2.5 a secondary source has been also identified, which contributed to 17% of the mass. A complete characterization of industrial emission plumes during their impact on the ground allowed for the identification of tracer species for specific point sources, such as petrochemical, metallurgic, and fertilizer and phosphate production industries.

    The Flora-On dataset currently includes 253,310 occurrence records for the class Embryopsidae (vascular plants), comprising data collated via the platform http://flora-on.pt/ relating to observation records of vascular plants across mainland Portugal. Observations are uploaded directly to the database primarily by experienced botanists and naturalists, typically on a weekly basis, and consist of geo-referenced data points for species (or infraspecific taxa) along with their date of observation and phenological state. The Flora-On project aims to compile and make publicly accessible chorological, ecological, morphological and photographic information for the entire vascular flora of Portugal. The project's website offers powerful query and visualization capabilities, of which we highlight the probabilistic bioclimatic and phenological queries which operate based on the empirical density distributions of species in those variables. Flora-On was created and continues to be maintained by volunteers who are Associate members of Sociedade Portuguesa de Botânica (Botanical Society of Portugal). Given its focus on research-grade and current data, the Flora-On project represents a significant contribution to the knowledge of the present distribution and status of the Portuguese flora.

    Document available in extended abstract form only. On 1998 a 137 Cs source was accidentally molten in the installations of a Spanish company of stainless steel production. Not being aware of the contamination with Cs, the produced powder was treated in an inert plant and these inert materials were normally used as filling material to restore phosphogypsum piles. The contaminated material ended up in the phosphogypsum piles at the Center of Inert Recuperation (CRI), located at the salt marshes of Huelva (Spain). This is a large extension oriented towards the sea with marsh vegetation subject to the tide. Since the cesium contamination was discovered, this zone has been thoroughly analyzed in order to evaluate the radiological impact of the presence of cesium and the possible contamination of soils and water in the surrounding. Recently, in two different locations at CRI, permeable reactive barriers were constructed to retard cesium migration. The main component of these barriers is a clay material called Rojo Carbonero (RC), whose properties as cesium sorbent have to be analyzed in depth. This material is mainly formed by: quartz (27%), phyllosilicates (58%), dolomite (8%), feldspar (2%), hematite (5%). The clayey fraction (<2 μm) is composed by a 98% of illite and the rest is chlorite/kaolinite. Different studies were carried out to quantify the sorption of cesium in this material previous to the construction of the reactive barriers. Due to the large variability of the chemical composition of the waters at the site a significant variability of sorption values, in terms of distribution coefficients (Kd) was also observed. In order to predict the migration of cesium in these barriers, taking into account this variability and the presence of competing ions, a detailed experimental study was carried out with the aim of determining the selectivity coefficients of cesium with respect to the main ions present in the water. Basically, the material was converted in

    Onchocerca lupi causes ocular pathology of varying severity in dogs from south-western United States, western Europe and northern Asia. This filarioid has also been recognized as a zoonotic agent in Tunisia, Turkey, Iran and the USA, though the information about the biology and epidemiology of this infection is largely unknown. In Europe, O. lupi has been reported in dogs from Germany, Greece, Hungary, Portugal and Romania and in a cat from Portugal. The present study was designed to establish the occurrence of O. lupi in dogs in southwestern Spain. In the present study a total of 104 dogs of different breed, sex, and age living in a shelter in Huelva (SW Spain) were examined. Skin snip samples were collected using a disposable scalpel in the forehead and inter-scapular regions and stored as aliquots in saline solution (0.5 ml) before light microscopy observation of individual sediments (20 μl) and molecular examination. Of the 104 dogs examined, 5 (4.8 %) were skin snip-positive for O. lupi: two by microscopy and three by PCR. One of the O. lupi infected dogs showed neurological signs but ocular ultrasonography and/or MRI detected no abnormalities. This first report of O. lupi infection in dogs in southern Spain expands the range of geographical distribution of this parasite and sounds an alarm bell for practitioners and physicians working in that area.

    A field study was carried out in the south of the Iberian Peninsula in an industrial area in the neighbourhood of Huelva city, SW Spain, and in a natural area (Donana National Park) for comparison, to estimate the genetic risk induced by environmental pollution in wild mice. Genotoxic effects in a sentinel organism, the Algerian mice (Mus spretus) free living in the industrial area were compared with animals of the same species living in the natural protected area. The single cell gel electrophoresis, or Comet assay, was performed as a genotoxicity test in peripheral blood of mice. Our results clearly show that mice free living in the contaminated area bear a high burden of genetic damage as compared with control individuals. The results suggest that the assessing of genotoxicity levels by the Comet assay in wild mice can be used as a valuable test in pollution monitoring and environmental conservation. - We have found an increased genotoxic damage in wild mice in a highly polluted area from industry, mining and agriculture in SW Spain, as assessed by the Comet assay.

    Lead, cadmium, arsenic and nickel are present in the air due to natural and anthropogenic emissions, normally joined to particles. Human health and ecosystems can be damaged by high atmospheric levels of these metals, since they can be introduced in organisms via inhalation or ingestion. Small particles are inhaled and embebed in lungs and alveolus more easily than coarse particles. The CHIMERE model is a eulerian air quality model extensively used in air quality modelling. Metals have been recently included in this model in a special version developed in the CIEMAT modelling group (Madrid, Spain). Vivanco et al. (2011) and Gonzalez et al. (2012) showed an evaluation of the model performance for some metals in Spain and Europe. In these studies, metals were considered as fine particles. Nevertheless there is some observational evidence of the presence of some metals also in the coarse fraction. For this reason, a new attempt of modelling metals considering a fine (<2.5 μm) and coarse (2.5-10 μm) fraction has been done. Measurements of metal concentration in PM10, PM2.5 and PM1 recorded in Spain were used to obtain the new metal particle distribution size. On the other hand, natural emissions, not considered in the above mentioned studies, were implemented in the model, by considering metal emissions associated to dust resuspensiont. An evaluation of the new version is presented and discussed for two domains in Spain, centered on Barcelona and Huelva respectively. (Author)

(2012) showed an evaluation of the model performance for some metals in Spain and Europe. In these studies, metals were considered as fine particles. Nevertheless there is some observational evidence of the presence of some metals also in the coarse fraction. For this reason, a new attempt of modelling metals considering a fine (<2.5 μm) and coarse (2.5-10 μm) fraction has been done. Measurements of metal concentration in PM10, PM2.5 and PM1 recorded in Spain were used to obtain the new metal particle distribution size. On the other hand, natural emissions, not considered in the above mentioned studies, were implemented in the model, by considering metal emissions associated to dust resuspensiont. An evaluation of the new version is presented and discussed for two domains in Spain, centered on Barcelona and Huelva respectively. (Author)

    Two marine invertebrates, the crab Carcinus maenas and the clam Ruditapes philippinarum, were used as bioindicator species to assess contamination when exposed in situ to sediment from different sites from four Spanish ports Cadiz (SW Spain), Huelva (SW Spain), Bilbao (NE Spain) and Pasajes (NE Spain). In an attempt to determine sediments toxicity, a combination of exposure biomarkers was analyzed in both species: metallothionein-like-proteins (MTLPs), ethoxyresorufin O-deethylase (EROD), glutathione S-transferase activity (GST), glutathione peroxidase (GPX) and glutathione reductase (GR). In parallel, physical and chemical characterization of the different sediments was performed and biological responses related to the contaminants. Significant induction of MTLPs was observed when organisms were exposed to metal contaminated sediments (port of Huelva), and EROD and GPX activities after exposure to sediments containing organic compounds (port of Bilbao and Pasajes). No significant interspecies differences were observed in biomarker responses except for the GST and GR. - A battery of biomarkers shows exposure to metals and organic compounds

    Full Text Available The canopy-forming macroalga Gelidium corneum (Hudson J.V. Lamouroux plays a major role in the functioning of the subtidal ecosystem of the Cantabrian Sea (northern Spain. Despite its importance, little is known about the factors that may potentially affect the distribution pattern of its epiphytic flora. Here we examine two indirect factors: coastal orientation (N and NW and depth (3 and 7 m, as proxies for wave exposure and light availability, respectively. We test their effects on the total epiphytic load, alpha diversity (species richness, Shannon, Simpson and evenness measures and multivariate structure of the epiphytic flora growing on G. corneum in subtidal waters off the Basque coast. Plocamium cartilagineum, Dictyota dichotoma and Acrosorium ciliolatum were found to be the most common epiphytes. Significant interactive effect of coastal orientation and depth were observed for species composition and abundance of epiphytic flora. Increased wave exposure resulted in a lower epiphyte load and a less diverse community, suggesting that under high hydrodynamic conditions epiphytes were more likely to become dislodged from hosts. However, light availability only had a significant effect on the distribution of epiphytes below a certain threshold of wave action, with the epiphytic load being 30-40% greater on shallow bottoms.

    One of the most important social phenomena in the global context is the flow of immigration from developing countries, motivated by economic and employment related issues. Discrimination can be approached as a health risk factor within the immigrant population's working environment, especially for those immigrants at greater risk from social exclusion and marginalisation. The aim of this study is to research perceptions of discrimination and the specific relationship between discrimination in the workplace and health among Spain's immigrant population. A qualitative study was performed by means of 84 interviews and 12 focus groups held with immigrant workers in five cities in Spain receiving a large influx of immigrants (Madrid, Barcelona, Valencia, Alicante and Huelva), covering representative immigrant communities in Spain (Romanians, Moroccans, Ecuadorians, Colombians and Sub-Saharan Africans). Discourse narrative content analysis was performed using pre-established categories and gradually incorporating other emerging categories from the immigrant interviewees themselves. The participants reported instances of discrimination in their community and working life, characterised by experiences of racism, mistreatment and precarious working conditions in comparison to the Spanish-born population. They also talked about limitations in terms of accessible occupations (mainly construction, the hotel and restaurant trade, domestic service and agriculture), and described major difficulties accessing other types of work (for example public administration). They also identified political and legal structural barriers related with social institutions. Experiences of discrimination can affect their mental health and are decisive factors regarding access to healthcare services. Our results suggest the need to adopt integration policies in both the countries of origin and the host country, to acknowledge labour and social rights, and to conduct further research into individual

    Physical and chemical parameters of fresh berries from three southern high bush (ONeal, Sharp blue and Misty) blueberry cultivars grown in Huelva (Southwestern Spain) under two production systems were measured and evaluated. ANOVA applied to data yielded significant differences between production systems for mean fruit size and mean fruit fresh weight (P<0.05), although main effects on physical and chemical characteristics of fruit were due to cultivar. All three cultivars showed significantly different means (P<0.05) for fruit fresh weight, and all chemical characteristics. Stepwise discriminant analysis (SDA) for classification and identification of the cultivars based on physico-chemical properties of samples of fruits was performed. The model obtained gave high percentages of correct classification and prediction (81.1% and 78.4%, respectively). The variables with higher discriminating power were fruit titratable acidity, fruit size and fruit sugar content. (Author)

    This study, which is motivated by the substantial morbidity of local signs of mucositis and generalized symptoms that result from mucositis induced by therapeutic irradiation, has the following objectives: To investigate if it is possible to prevent irradiation mucositis via oral flora elimination, and, if it is true that flora plays a role in irradiation mucositis, what fraction of the oral flora may be involved; to evaluate oral Gram-negative bacillary carriage; to investigate the possibility to eradicate Gram-negative bacilli from the oral cavity; to evaluate oral yeast carriage; to investigate the possibility to eradicate yeasts stomatitis and the 'selectivity' of elimination of flora. Two methods are described for monitoring alterations of mucositis of the oral cavity and changes in oral flora. Chlorhexidine has been tested as the commonly used prophylaxis. The effect of chlorhexidine 0.1% rinses on oral flora and mucositis has been studied in a prospective placebo controlled double blind randomized programme. The results of the influence of saliva on the antimicrobial activity of chlorhexidine and the results of selective elimination of oral flora in irradiated patients who have head and neck cancer are reported. Salivary inactivation of the topical antimicrobials used for selective elimination of oral flora has been studied and the results are reported. Finally, the objectives that have been achieved (or not) are delineated. The significance of the results of the study are discussed in terms of published information and further lines of research are suggested. (author). 559 refs.; 29 figs.; 20 tabs

    Cool roofs are an inexpensive method to save energy and to improve the comfort level in buildings in mild and hot climates. A high scale implementation of cool roofs in Andalusia, in the south of Spain, could potentially save 295,000 kWh per year, considering only residential buildings with flat roofs using electrical heating. At the current energy prices, consumers can save 59 million euros annually in electricity costs and the emission of 136,000 metric tons of CO 2 can be directly avoided every year from the production of that electricity. If radiative forcings are considered, Andalucía can potentially offset between 9.44 and 12 Mt of CO 2 . All the provinces in the rest of Spain are also studied in this paper. The biggest savings are achieved in Gran Canaria (48%), Tenerife (48%), Cádiz (36%), Murcia (33%), Huelva (30%), Málaga (29%), Almería (29%) and Sevilla (28%), where savings are greater than 2 euros per square meter of flat roof for old buildings with dark roofs. For the biggest cities the range of savings obtained are: between 7.4% and 11% in Madrid, between 12% and 18% in Barcelona and between 14% and 20% in Valencia. -- Highlights: ► We estimate potential savings in energy, CO 2 , and money for cool roofs in Spain (residential sector with flat roofs). ► Average savings are of around one euro per square meter in the biggest cities. ► Potential savings are of more than 2 €/m 2 in the hottest cities. ► In Andalusia the potential savings are 300 MWh, 60 millions euro and 136,000 tons of CO 2 per year. ► With forcings, the CO 2 equivalence of cool roofs in Andalusia is between 9 and 12 Mt.

    To describe the geographic distribution patterns of the municipal incidence of the most common tumours in the Huelva province (Spain) as compared to the estimated incidence for all of Spain. Relative risk (RR) was computed based on the conditional autoregressive model proposed by Besag, York and Mollié by applying the INLA tool to the cancer data for 2007-2011 for the following tumour locations: colon, rectum and anus (men and women); trachea, bronchia, and lungs, prostate and bladder in men; and breasts in women. The RR was presented in in choropleth and isopleth (with kriging interpolation) risk maps. RR for bladder cancer in men was greater than 1.0 in all municipalities, with confidence intervals over 1.0 in four municipalities; Madrid having a 1.56 RR (95%CI 1.30-1.67). For prostate cancer, a posteriori probabilities were below 0.1 in 68 of the 79 municipalities. For lung cancer, nine municipalities had confidence limits below 1.0, almost all of them in western Spain. For women, the RR for breast cancer was significantly higher in the capital of province area. The cancer incidence rates for the Huelva province were, in general, similar to those estimated for Spain, standing out bladder cancer in men (35% higher) and prostate cancer (30% lower). In the Huelva province, there is a geographical municipal distribution of cancer incidence with well-defined patterns for some specific tumour locations, with overall incidence rates very similar to those in the rest of Spain.

    Full Text Available The role of living collections-based research and discovery has been a prominent feature throughout the history of evolution and advance of botanical science: such research is the core and soul of the botanical gardens. Currently, there are c. 162 Chinese botanical gardens, harboring c. 20,000 species in China. As an example of initiatives to utilize the garden cultivated flora to address plant diversity conservation and germplasm discovery for sustainable agriculture and the bio-industries, the Ex situ Flora of China project aims to catalog and document this mega-diversity of plants that are cultivated in the Chinese botanical gardens. The concept of Ex situ Flora of China is a complete new formulation of species, based on garden cultivated individuals and populations, to obtain better morphological descriptions, provide multi-purpose applicability and a fundamental data service that will support national bio-strategies and bio-industries. It emphasises integrative information, accurately collected from living collections across different Chinese botanical gardens, on biology, phenology, cultivation requirements and uses of plant resources, which are normally not available from traditional Floras based on herbarium specimens. The ex situ flora should provide better information coverage for taxonomy, biological and introduction and collection data and color photos of stems, leaves, flowers, fruits and seed, as well as useful information of cultivation key points and main use of each plant. In general, the Ex situ Flora of China provides more useful information than the traditional Flora Reipublicae Popularis Sinicae. The project of Ex situ Flora of China is planned to be one of the most important initiatives of the plant diversity research platform for sustainable economic and social development in China.

    Full Text Available Abstract Background Spain shows the highest bladder cancer incidence rates in men among European countries. The most important risk factors are tobacco smoking and occupational exposure to a range of different chemical substances, such as aromatic amines. Methods This paper describes the municipal distribution of bladder cancer mortality and attempts to "adjust" this spatial pattern for the prevalence of smokers, using the autoregressive spatial model proposed by Besag, York and Molliè, with relative risk of lung cancer mortality as a surrogate. Results It has been possible to compile and ascertain the posterior distribution of relative risk for bladder cancer adjusted for lung cancer mortality, on the basis of a single Bayesian spatial model covering all of Spain's 8077 towns. Maps were plotted depicting smoothed relative risk (RR estimates, and the distribution of the posterior probability of RR>1 by sex. Towns that registered the highest relative risks for both sexes were mostly located in the Provinces of Cadiz, Seville, Huelva, Barcelona and Almería. The highest-risk area in Barcelona Province corresponded to very specific municipal areas in the Bages district, e.g., Suría, Sallent, Balsareny, Manresa and Cardona. Conclusion Mining/industrial pollution and the risk entailed in certain occupational exposures could in part be dictating the pattern of municipal bladder cancer mortality in Spain. Population exposure to arsenic is a matter that calls for attention. It would be of great interest if the relationship between the chemical quality of drinking water and the frequency of bladder cancer could be studied.

    The present work concerns the distribution and mobility of heavy metals (Fe, Mn, Cu, Zn and Cd) in the surrounding soils of a mine site and their transfer to wild flora. Thus, soils and plants were sampled from a mining valley in NW Madrid (Spain), and total and extractable heavy metals were analysed. Soils affected by mining activities presented total Cd, Cu and Zn concentrations above toxic thresholds. The percentage of extractable element was highest for Cd and lowest for Cu. A highly significant correlation was observed between the total and extractable concentrations of metals in soils, indicating that, among the factors studied, total metals concentration is the most relevant for heavy metals extractability in these soils. (NH(4))(2)SO(4)-extractable metal concentrations in soils are correlated better with metal concentrations in several plant species than total metals in soils, and thus can be used as a suitable and robust method for the estimation of the phytoavailable fraction present in soils. Twenty-five vascular plant species (3 ferns and 22 flowering plants) were analysed, in order to identify exceptional characteristics that would be interesting for soil phytoremediation and/or reclamation. High Cd and Zn concentrations have been found in the aerial parts of Hypericum perforatum (Cd), Salix atrocinerea (Cd, Zn) and Digitalis thapsi (Cd, Zn). The present paper is, to the best of our knowledge, the first report of the metal accumulation ability of the two latter plant species. The phytoremediation ability of S. atrocinerea for Cd and Zn was estimated, obtaining intervals of time that could be considered suitable for the phytoextraction of polluted soils.

    The present study seeks to estimate the impact of industrial emissions and harbour activities on total atmospheric deposition in an Atlantic coastal area in the southwest of the Iberian Peninsula. Three large industrial estates and a busy harbour have a notable influence on air quality in the city of Huelva and the surrounding area. The study is based on a geochemical characterization of trace elements deposited (soluble and insoluble fractions) in samples collected at a rate of 15 days/sample from June 2008 to May 2011 in three sampling sites, one in the principal industrial belt, another in the city of Huelva, and the last, 56 km outside Huelva city in an area of high ecological interest. The industrial emissions emitted by the Huelva industrial belt exert a notable influence on atmospheric deposition. Major deposition fluxes were registered for Fe, Cu, V, Ni, P, Pb, As, Sn, Sb, Se and Bi, principally in the insoluble fraction, derived from industrial funnel emissions and from harbour activities. Metals such as Mn, Ni, Cu and Zn, and elements such as P also have a significant presence in the soluble fraction converting them into potentially bio-available nutrients for the living organism in the ocean. A principal component analysis certifies three common emissions sources in the area: 1) a mineral factor composed mainly of elements derived from silicate minerals mixed with certain anthropogenic species (Mg, K, Sr, Na, Al, Ba, LREE, Li, Mn, HREE, Ti, Fe, Se, V, SO-, Ni, Ca and P); 2) an industrial factor composed of the same trace elements in the three areas (Sb, Mo, Bi, As, Pb, Sn and Cd) thus confirming the impact of the emissions from the Huelva industrial belt on remote areas; and 3) a marine factor composed of Na, Cl, Mg and SO.

Method: Twenty-four specimens were collected from pregnant Kunming mouse including 8 mice of early embryonic (12-13 days) gastrointestinal tissues, 8 cases of late embryonic (19-20 days)gastrointestinal tissues, 8 of late pregnancy placental tissues.The 24 samples were extracted by DNeasy Blood & Tissue kit for high-throughput DNA sequencing. Result: The level of Proteobacteria, Bacteroidetes, Actino-bacteria and Firmicutes were predominantin all specimens.The relative content of predominant bacterial phyla in each group: Proteobacteria (95.00%, 88.14%, 87.26%), Bacteroidetes(1.71%, 2.15%, 2.63%), Actino-Bacteria(1.16%, 4.10%, 3.38%), Firmicutes(0.75%, 2.62%, 2.01%). At the level of family, there were nine predominant bacterial families in which Enterobacteriaeae , Shewanel laceae and Moraxellaceae were dominant.The relative content of dominant bacterial family in eachgroup: Enterobacteriaeae (46.99%, 44.34%, 41.08%), Shewanellaceae (21.99%, 21.10%, 19.05%), Moraxellaceae (9.18%, 7.09%, 5.64%). From the species of flora, the flora from fetal gastrointestinal in early pregnancy and late pregnancy (65.44% and 62.73%) were the same as that from placenta tissue in the late pregnancy.From the abundance of bacteria, at the level of family, the same content of bacteria in three groups accounted for 78.16%, 72.53% and 65.78% respectively. Conclusion: It was proved that the gastrointestinal bacterial flora of mouse embryos and the placenta tissue bacterial flora were colonized. At the same time the bacteria are classified.

    Polin, Michael R; Kawasaki, Amie; Amundsen, Cindy L; Weidner, Alison C; Siddiqui, Nazema Y

    2017-06-01

    To determine whether mixed-flora preoperative urine cultures, as compared with no-growth preoperative urine cultures, are associated with a higher prevalence of postoperative urinary tract infections (UTIs). This was a retrospective cohort study. Women who underwent urogynecologic surgery were included if their preoperative clean-catch urine culture result was mixed flora or no growth. Women were excluded if they received postoperative antibiotics for reasons other than treatment of a UTI. Women were divided into two cohorts based on preoperative urine culture results-mixed flora or no growth; the prevalence of postoperative UTI was compared between cohorts. Baseline characteristics were compared using χ 2 or Student t tests. A logistic regression analysis then was performed. We included 282 women who were predominantly postmenopausal, white, and overweight. There were many concomitant procedures; 46% underwent a midurethral sling procedure and 68% underwent pelvic organ prolapse surgery. Preoperative urine cultures resulted as mixed flora in 192 (68%) and no growth in 90 (32%) patients. Overall, 14% were treated for a UTI postoperatively. There was no difference in the proportion of patients treated for a postoperative UTI between the two cohorts (25 mixed flora vs 13 no growth, P = 0.77). These results remained when controlling for potentially confounding variables in a logistic regression model (adjusted odds ratio 0.92, 95% confidence interval 0.43-1.96). In women with mixed-flora compared with no-growth preoperative urine cultures, there were no differences in the prevalence of postoperative UTI. The clinical practice of interpreting mixed-flora cultures as negative is appropriate.

    Full Text Available After thorough planning, an Ethiopian Flora Project has recently been initiated, financed by the Ethiopian Science and Technology Commission from a Swedish grant. The planning was effected by a working group including representatives of the Biology Department at Addis Ababa University and the Institute of Systematic Botany in Uppsala as well as some international experts selected by AETFAT, and was finalized by an Ethiopian Flora Committee. The project leader is Professor Tewolde Berhan G. Egziabher in Addis Ababa, assisted by an Ethiopian secretariat under the Director of the National Herbarium. A European counterpart secretariat, headed by the author, has also been organized with Dr I. Hedberg as co-ordinator. Collecting expeditions to insufficiently known areas, loans from the Addis Ababa Herbarium to collaborating taxonomists, and other activities inside Ethiopia are organized by the Ethiopian secretariat, whereas the Uppsala secretariat is responsible for the initiation and co-ordination of the taxonomic revisions and family accounts needed for the Flora. Collaborators for several of the roughly 200 families of Ethiopian vascular plants have already been secured, but many more remain to be covered. AETFAT members with specialist knowledge of the remaining families are requested to help fill the gaps in our list of contributors.

    1969-01-01

    The lichen flora of the central English county of Derbyshire is described and discussed. The distribution of each species is described with reference to 10 km grid squares. In areas where air pollution is severe, very few species are found, even if otherwise suitable habitants are available. Air pollution is therefore considered to be the dominant factor affecting the present lichen flora of the county. The lichen communities have been studied and nineteen unions belonging to eleven federations are recognized. Several species are discussed taxonomically. 182 references, 15 tables.

    In the South of Spain, major industrial estates (e.g. Huelva) exist alongside ecologically interesting zones (e.g. Doñana National Park). Between June 2005 and June 2006, PM10 and PM2.5 were measured, for total mass, organic carbon (OC) and elemental carbon (EC) chemical composition, at a station in an ecologically interesting area located near Doñana National Park and an urban background area with industrial influence. The mean OC concentration is higher in the urban background (3.5 microg m(-3)) than in the rural monitoring station (2.8 microg m(-3)) as a consequence of local emissions (e.g. traffic). A total of 82% of TC is OC in the rural station, while the urban background station reveals 70% and 73% of TC in the PM10 and PM2.5 mass, respectively. The study of air-mass origin and characterization of carbonaceous species in the course of simultaneous sampling in rural and urban background monitoring stations differentiated three long-range air-mass transports: a North-African dust outbreak, Atlantic Advection and Continental (N-NW) episodes, the origins of the first and last of which are more heavily influenced by the anthropogenic emissions from industrial estates located around the city of Huelva (Punta del Sebo and Nuevo Puerto). Higher values were measured for OC and EC in the study area during the North-African dust outbreak, similar to those obtained during the Continental episode (N-NW), which was clearly influenced by industrial emissions, followed by the Atlantic Advection episodes. The comparison of carbon species with air-mass origin can help to discriminate the origin and source of particulate matter, as well as to determine the urban impact on rural areas.

    Full Text Available The spring flora was analyzed on six cemeteries in Odessa, such cemeteries as Vtoroe xristianskoe, Troickoe, Tairovskoe, Trete evrejskoe, Oficerskoe (Dmitrievskое and Severnoe. There were found and identified 235 species of plants, which belong to 186 genera and 67 families. There was taken a taxonomic analysis of flora of the cemeteries also of spreding of plants by ekobiomorphs, the analysis of hronotyp and origin. The proportion of the flora on the cemeteries is 1:2,8:3,5. The dominant family of the flora of Odessa’s cemeteries is Asteraceae. There are other leading families such as Rosaceae, Fabaceae, Poaceae, Brassicaceae, Lamiaceae. Herbs and trees are dominant among the life forms. Mesophytes and kseromezophytes are in the majority among hihromorphs. Heliophytes are on the first place by adapting to the light. Our results showed that the adventitious plants occupy up to 44% of all amount of plants at the cemeteries in Odessa. Kenophytes is a dominant group among them. Floragenetics analysis revealed the dominance of the plants from Asia. There have been allocated plants that were met at all six cemeteries independently of the location religious and age characteristics of the cemetery. "Core" of the flora of Odessa’s cemetery have made weed Acer negundo L., Ballota nigra L. and decorative Hedera helix L., Centaurea dealbata Willd., Buxus sempervirens L., Convallaria majalis L., Sedum kamtschaticum Fisch., Thuja occidentalis L., Hemerocalis fulva (L.

    Full Text Available The composition, life forms and the distribution of plants in Libya were studied. The results show that in Libya there are 2103 species that belong to 856 genera and 155 families. The distribution among Libyan seed plants was characterized by a high proportion of herbs (annual to perennial, unlike the low number of woody (tree and shrub species; these have an important influence on the structure of floral composition. The geographic element of the flora was predominantly tropical and Mediterranean. The local plants belong to representative tropical desert flora. The presence and distribution characteristics of flora in Libya show that climate, environmental condition, ecological amplitude and adaptive capacity of the plants have a determinative influence on the floristic stock in the area studies.

    Few studies document plants in caves. Our field observations of a widespread and seemingly angiosperm-rich cave flora in SW China lead us to test the following hypotheses, 1) SW China caves contain a diverse vascular plant flora, 2) that this is a relic of a largely absent forest type lacking endemic species, and 3) that the light environment plants occupy in caves is not distinct from non-cave habitats. To do so we surveyed 61 caves and used species accumulation curves (SAC) to estimate the total diversity of this flora and used a subsample of 14 caves to characterise the light environment. We used regional floras and existing conservation assessments to evaluate the conservation value of this flora. We used observations on human disturbance within caves to evaluate anthropogenic activities. Four-hundred-and-eighteen vascular plant species were documented with SACs predicting a total diversity of 529–846. Ninety-three percent of the species documented are known karst forest species, 7% are endemic to caves and 81% of the species are angiosperms. We demonstrate that the light environment in caves is distinct to that of terrestrial habitats and that a subset of the flora likely grow in the lowest light levels documented for vascularised plants. Our results suggest that the proportion of species threatened with extinction is like that for the terrestrial habitat and that almost half of the entrance caverns sampled showed signs of human disturbance. We believe that this is the first time that such an extensive sample of cave flora has been undertaken and that such a diverse vascular plant flora has been observed in caves which we predict occurs elsewhere in SE Asia. We argue that the cave flora is an extension of the karst forest understory present prior to catastrophic deforestation in the 20thC. We suggest that within SW China caves serve as both refuges and a valuable source of germplasm for the restoration of karst forest. We also propose that caves represent a

    The effect of screening and treatment for abnormal vaginal flora on the reduction of preterm deliveries remains controversial. We evaluated whether this screening and treatment reduces the preterm delivery rate for general-population pregnant women. Pregnant women of the Intervention group (n = 574) underwent the screening test and the treatment of vaginal metronidazole during the early second trimester, and those of the Control group (n = 1,161) did not. We compared the preterm delivery rate between these two groups. We also compared the profiles of vaginal flora of the preterm delivery cases with those of the pregnant women with a normal course. There was no significant difference in the preterm delivery rate between these two groups. However, in the preterm delivery cases, a frequent shift to intermediate flora was observed not before but after the screening in the Intervention group. This shift may explain why most of the previous studies failed in regard to the prevention of preterm deliveries. PMID:24762852

    2010-01-01

    Marine floras, such as bacteria, actinobacteria, cyanobacteria, fungi, microalgae, seaweeds, mangroves, and other halophytes are extremely important oceanic resources, constituting over 90% of the oceanic biomass. They are taxonomically diverse, largely productive, biologically active, and chemically unique offering a great scope for discovery of new anticancer drugs. The marine floras are rich in medicinally potent chemicals predominantly belonging to polyphenols and sulphated polysaccharides. The chemicals have displayed an array of pharmacological properties especially antioxidant, immunostimulatory, and antitumour activities. The phytochemicals possibly activate macrophages, induce apoptosis, and prevent oxidative damage of DNA, thereby controlling carcinogenesis. In spite of vast resources enriched with chemicals, the marine floras are largely unexplored for anticancer lead compounds. Hence, this paper reviews the works so far conducted on this aspect with a view to provide a baseline information for promoting the marine flora-based anticancer research in the present context of increasing cancer incidence, deprived of the cheaper, safer, and potent medicines to challenge the dreadful human disease.

    To evaluate associations between alterations in vaginal flora and clinical symptoms in low-risk pregnant women. Vaginal specimens from 245 pregnant women were analyzed by microscopy for vaginal flora. Signs and symptoms of vaginal infection were determined by patient interviews and gynecologic examinations. Abnormal vaginal flora was identified in 45.7% of the subjects. The final clinical diagnoses were bacterial vaginosis (21.6%), vaginal candidosis (10.2%), intermediate vaginal flora (5.2%), aerobic vaginitis (2.9%), mixed flora (2.9%) and other abnormal findings (2.9%). The percentage of women with or without clinical signs or symptoms was not significantly different between these categories. The presence of vaginal odor or vaginal discharge characteristics was not diagnostic of any specific flora alteration; pruritus was highly associated with candidosis (p vaginal odor was associated with bacterial vaginosis (p = 0.0026). The prevalence of atypical vaginal flora is common in our low-risk pregnant population and is not always associated with pathology. The occurrence of specific signs or symptoms does not always discriminate between women with different types of atypical vaginal flora or between those with abnormal and normal vaginal flora.

    Full Text Available The analysis of the Polish flora of the order Uredinales is based on a simultaneously published descriptive elaboration (M a j e w s k i 1977, ms. The information on the Uredinales flora of Poland has been compared as far as possible with the data obtained from the analysis of the flora of sever al other countries in Europe with a different type of vegetations. In a chapter devoted to the statistics of the flora of Polish rust fungi the number of genera and species of these fungi in Poland is discussed, as well as their life cycles and host plants. The distribution of Uredinales in Poland is analysed on the basis of the A r w i d s s o n - D u r r i e u classification modified by the author, and particular attention is paid to the depedence of the range of the fungus on its life cycle and the occurrence of the host. Changes in the flora a result of its synantropization are also considered. The Polish Uredinales are divided into several groups on the basis of range, and example of their distribution involving historical factors are discussed.

    Full Text Available Background: The aim of this study was to assess the pattern of periurethral bacterial flora in uncircumcised boys and to evaluate the effect of circumcision on alteration of periurethral uropathogenic bacterial flora. Materials and Methods: Pattern of periurethral bacterial flora before and after circumcision was studied prospectively in 124 boys. The results were analysed to compare change in bacterial colonisation before and after circumcision. Results: The age range was 6 weeks to 96 months. Most (94.3% of the boys had religious indication and 5.7% had medical indication for circumcision. E. coli, Proteus and Klebsiella were most common periurethral bacterial flora in uncircumcised subjects. Coagulase-negative staphylococcus and Staphylococcus aureus was most common periurethral bacterial flora in circumcised subjects. In 66.1% of circumcised subjects, no bacteria were grown from periurethral region. Conclusion: We conclude that presence of prepuce is associated with great quantity of periurethral bacteria, greater likelihood of the presence of high concentration of uropathogens and high incidence of urinary tract infection (UTI. This study provides circumstantial evidence supporting the idea that early circumcision may be beneficial for prevention of UTI.

    The microbial flora in the digestive tract has been recently studied in relation to metabolic diseases. There are relations to both type 1 diabetes and type 2 diabetes. The intestinal flora is affected by diet, physical exercise and it significantly changes after bariatric surgeries. Giving birth by caesarean section affects the gut flora development and increases the risk of type 1 diabetes in further life of the child. Obese patients with type 2 diabetes may lack protective microbes which improve glucoregulation in the experiment or on the contrary their patogenous microbes may grow which have been proven to even be able to penetrate into abdominal adipose tissue and play a role, inter alia, in the hepatic impairment and systemic inflammation. Also vaccination against these microbes is under consideration. Microbiome can be also positively affected by metformin treatment. The transfer of intestinal flora by means of fecal transplantation can improve glucoregulation. The influencing of intestinal flora is likely to become a new mechanism of diabetes treatment.

    A detailed physical and chemical characterisation of total suspended particles (TSP) in the highly industrialised city of Huelva (southwestern Spain) was carried out. The results evidenced a coarse grain-size prevalence (PM 10 accounting for only 40% of TSP mass, 37 and 91 μg/m 3 , respectively). PM 10 levels are in the usual range for urban background sites in Spain. The crustal, anthropogenic and marine components accounted for a mean of a 40%, 24% and 5% of bulk TSP, respectively. As expected from the industrial activities, relatively high PO 4 3- and As levels for an urban site were detected. In addition to the crustal and marine components, source apportionment analysis revealed three additional emission sources influencing the levels and composition of TSP: (a) a petrochemical source, (b) a mixed metallurgical-phosphate source, (c) and an unknown source (Sb and NO 3 - ). Due to the high local emissions, the mean TSP anthropogenic contribution (mostly PM 10 ) obtained for all possible air mass transport scenarios reached 18-29 μg/m 3 . The 2010 annual EU PM 10 limit value (20 μg/m 3 ) would be exceeded by the anthropogenic load recorded for all the air mass transport scenarios, with the exception of the North Atlantic transport (only 15% of the sampling days). Under African air mass transport scenarios (20% of sampling days), the TSP crustal contribution reached near three times the local crustal contribution. It must be pointed out that this crustal input should diminish when sampling PM 10 due to the dominant coarse size distribution of this type of particles. (author)

    Spanish strawberries are an export success. Spain is the second largest producer of this fruit and it has been the world's leading strawberry exporter for years. In 2012, strawberry exports were approximately 95% of total strawberry production in Spain. The production of the red gold is concentrated in around 7000 hectares of intensive farming in the province of Huelva (south west Spain). At least 85% of all Spanish strawberries are produced in this region, in an area close to the UNESCO World Heritage Site Doñana National Park. The case of the strawberry production in Huelva makes an interesting case study for the integrated analysis of the water-food-land-political economy nexus. Its combination of bio-physical and socio-economic characteristics (local climatic conditions, agricultural techniques, environmental issues, food value chains, trade networks and socio-economic factors) are quite particular and form a case where social and natural issues coevolve. Supporters of the activity argue a high contribution to local GDP and job market and its strategic position in international markets. Critics maintain that this industry creates social and environmental conflicts. The strawberry from Huelva supplies early season strawberries to the richer markets of Germany and France and at the same time seems to fail in alleviating a provincial unemployment rate of 34%. The viability of the system is in danger: production costs are 70% higher than 20 years ago while the price per kilo has not changed or even decreased. In environmental terms, the strawberries of Huelva are irrigated with ground water withdrawn from aquifers that feed the water streams of the natural park. Half of the wells that extract the water are not legally registered for what the total amount of water withdrawal remains unknown. Should we promote the continuity of this activity? In this work, I perform a Multi-Scale Integrated Assessment of Societal and Ecosystem Metabolism (MuSIASEM) of Water for the

    Full Text Available The spring flora was analyzed on six cemeteries in Odessa, such cemeteries as Vtoroe xristianskoe, Troickoe, Tairovskoe, Trete evrejskoe, Oficerskoe (Dmitrievskое and Severnoe. There were found and identified 235 species of plants, which belong to 186 genera and 67 families. There was taken a taxonomic analysis of flora of the cemeteries also of spreding of plants by ekobiomorphs, the analysis of hronotyp and origin. The proportion of the flora on the cemeteries is 1:2,8:3,5. The dominant family of the flora of Odessa’s cemeteries is Asteraceae. There are other leading families such as Rosaceae, Fabaceae, Poaceae, Brassicaceae, Lamiaceae. Herbs and trees are dominant among the life forms. Mesophytes and kseromezophytes are in the majority among hihromorphs. Heliophytes are on the first place by adapting to the light. Our results showed that the adventitious plants occupy up to 44% of all amount of plants at the cemeteries in Odessa. Kenophytes is a dominant group among them. Floragenetics analysis revealed the dominance of the plants from Asia. There have been allocated plants that were met at all six cemeteries independently of the location religious and age characteristics of the cemetery. "Core" of the flora of Odessa’s cemetery have made weed Acer negundo L., Ballota nigra L. and decorative Hedera helix L., Centaurea dealbata Willd., Buxus sempervirens L., Convallaria majalis L., Sedum kamtschaticum Fisch., Thuja occidentalis L., Hemerocalis fulva (L.

    Full Text Available The estuary of Ría of Huelva, recognized like Reserve of the Biosphere by UNESCO, is affected by spills of diverse origin. The method Sistémico Multivariado (MSM, applied prior to harbor works or in economy, has been used to characterize the estuary in risk terms and environmental reliability. After determining the variables that take part and to describe the mechanisms of performance of toxics, these have been classified in cancerigenic and noncancerigenic. Criteria defined by Environmental Protection Agency have been used (EPA-EEUU, the “dose of reference” for the noncancerigenic ones, the “factor of fall” for the cancerigenic ones, paying attention to the “components of failure”. The reliability of the system has been analyzed and the one of each component, with which it must have the system “Ría of Huelva”, following methodology MSM on determination of the permissible reliability of a design system. The reliability of the system is despicable for the physiological conditions of the studied fish, meaning that determined species are condemned to their extinction or its absence of the place. One has seen the applicability of the MSM the characterization of the environmental state of certain environmental factors and ecosystems.

    The DAMOCLES network is a Spanish thematic network, started in 2004, whose main objective is the establishment of a link among the different groups that perform research on atmospheric aerosols in Spain. Under the DAMOCLES coordination, a field campaign was held in summer 2006 at the INTA installations (El Arenosillo, Huelva) for the intercomparison of different kind of instruments devoted to in - situ and columnar aerosol measurement. During this field campaign, two daily meteorological soundings were carried out at noon and midnight for characterization of the atmospheric condition. A plane was also flown by the National Institute of Aerospace Technology (INTA) to carry airborne sensors for measuring different atmospheric factors: meteorological parameters, ozone with a 2BTech analyzer, and aerosol particle size distributions in the range (0.01-2) microns, by using a PCASP probe. The columnar aerosol properties were measured by seven CIMEL CE318 sun photometers. For in situ aerosol characterization, high volume collectors (DIGITEL and MCV) with DIGITEL for PM10, PM2.5 and PM1 measurement were used, with two cascade impactors for particulate matter measurement in 7 -8 granulometric fractions. For the PM10, PM2.5 and PM1 measurement, quartz fibre filters of 150 mm diameter were adapted. Other in situ deployed instruments were a Scanning Mobility Particle Sizer (SMPS, Model 3936), two Aerodynamic Particle Sizer (APS Model 3321) and one Grimm Spectrometer (Model #190). For characterization of the aerosol scattering at ground level, three integrating nephelometers TSI-3563 were used. For the columnar profiling we deployed five LIDAR instruments. In this study we have related the columnar aerosol measurements retrieved with one CE318 sun photometer to the surface PM measurements, mainly in some interesting situations where nearby pollution sources were influencing the local atmosphere. For the sun photometric analysis, we have applied the EuroSkyRad package (ESR

El objetivo consiste en analizar los procesos de integración de niños inmigrantes en las escuelas de Huelva, reconociendo el rol social que cumple la escuela con respecto a su formación y sus oportunidades de socialización. En cuanto a la metodología, se recurre al análisis del discurso a partir de datos obtenidos en entrevistas en profundidad y talleres de interculturalidad donde participaron estudiantes, docentes y padres de familia. Como principal resultado del análisis, se plantea que el reto de la escuela no consiste en adaptar los contenidos curriculares a la diversidad existente en su entorno, sino que los debe gestionar efectivamente, atendiendo a las necesidades particulares de los inmigrantes.Pues allí, se ejercen derechos y deberes ciudadanos así como oportunidades de participación social. De esta manera, se concluye que el reto de la escuela en contextos interculturales consiste en fomentar la integración social a través del desarrollo de habilidades para la vida y la socialización. Para ello, debe reorientar la trayectoria vital de niños que han dejado sus raíces, promoviendo un diálogo entre su pasado y su presente, permitiéndoles desarrollar estrategias concretas en favor de la construcción de su proyecto de vida en un nuevo contexto social.

    An analysis of data on the species abundance of flora in 89 cities (urban flora) of the Russian Federation facilitated determination of its main factors. It has been revealed that the factors determining the abundance of native and alien components of urban flora vary. The city area and population number are the main factors of the total number of species and of the abundance of native species in urban flora. The diversity and participation of alien species increase in parallel with. the urbanization rate, anthropogenic transformation of the regions, and the age of cities and are in adverse correlation with the climate severity.

    The study of the evolutions of different wine pigment families, copigmentation/polymerisation processes and colour characteristics during the first year of ageing in oak barrel has allowed the assessment of the ageing aptitude of Syrah wines from "Condado de Huelva D.O.", a warm climate region. A total of 32 anthocyanic pigments were identified, including 14 major compounds from grape and 18 minor derivatives formed during the vinification. The anthocyanin profile changed towards more chemical complexity, being vitisin-like pyranoanthocyanins the predominant minor pigments during the first month of ageing. As wine became older, a progressive increase on the content of 4-vinylcatechin, 4-vinylphenol and 4-vinylcatechol compounds took place. Results showed that copigmentation occurred during the whole process of ageing inducing visual perceptible colour effects. Simultaneously to the copigmentation decrease, the degree of polymerisation increased during ageing, being maximum at 9 months old wines (77%). The colour of wines evolved progressively in a positive way from 3 to 9 months of ageing, becoming darker and with more vivid colour. However, from 9 to 12 months of ageing, the chemical structure of wines was negatively affected resulting in lighter, with more red-orange hues and less vivid colours. The inclusion of the chemical and colorimetric information on the PCA model allows us to reach very good discriminations among the Syrah wines with different wood contact period.

    Septoplasty is one of the most commonly performed procedures in otolaryngology practice. Prophylactic use of antibiotics is controversial. Disruption of nasal flora may predispose individuals to infection. We investigated the effect of antibiotic prophylaxis and septoplasty on nasal flora. We included 115 consecutive patients who underwent septoplasty because of symptomatic nasal septal deviation. Patients were divided into study and control groups. Study patients received prophylactic parenteral sodium cefazoline twice a day beginning intra-operatively and while the nasal packing remained in the nose for 48 h, and expandable polyvinyl acetate (Merocel) packing covered with antibiotic ointment containing 0.2% nitrofurazone was inserted into each nostril at the end of the operation. Control patients received neither parenteral antibiotic prophylaxis nor antibiotic ointment around the Merocel packs. Both groups received oral prophylactic cefuroxime axetil for 5 d after nasal packing was removed. Nasal flora was determined pre-operatively, post-operatively when nasal packing was removed, and 3 mo after surgery. Study patients were compared to control patients at pack removal and 1 mo after surgery The effect of antibiotic use in septoplasty on nasal flora was as follows: Increased isolation rate of gram-positive rods (p = 0.007), decreased methicillin-sensitive coagulase-negative staphylococci (p = 0.002). Pre-operative and post-operative culture results at 3 mo were compared. The effect of septoplasty on nasal flora was as follows: Decreased coagulase-negative staphylococci (p = 0.05), decreased Klebsiella (p flora. Antibiotics do not protect against S. aureus colonization and contribute to a decrease in normal flora. Antibiotics do not seem to confer benefit in terms of flora changes.

    In the Xinjiang region of Eurasia, sustained long-term and continuous cropping of cotton over a wide expanse of land is practiced, which requires application of high levels of pyrethroid and other classes of pesticides-resulting in high levels of pesticide residues in the soil. In this study, soil samples were collected from areas of long-term continuous cotton crops with the aim of obtaining microbial resources applicable for remediation of pyrethroid pesticide contamination suitable for the soil type and climate of that area. Soil samples were first used to culture microbial flora capable of degrading beta-cypermethrin using an enrichment culture method. Structural changes and ultimate microbial floral composition during enrichment were analyzed by high-throughput sequencing. Four strains capable of degrading beta-cypermethrin were isolated and preliminarily classified. Finally, comparative rates and speeds of degradation of beta-cypermethrin between relevant microbial flora and single strains were determined. After continuous subculture for 3 weeks, soil sample microbial flora formed a new type of microbial flora by rapid succession, which showed stable growth by utilizing beta-cypermethrin as the sole carbon source (GXzq). This microbial flora mainly consisted of Pseudomonas, Hyphomicrobium, Dokdonella, and Methyloversatilis. Analysis of the microbial flora also permitted separation of four additional strains; i.e., GXZQ4, GXZQ6, GXZQ7, and GXZQ13 that, respectively, belonged to Streptomyces, Enterobacter, Streptomyces, and Pseudomonas. Under culture conditions of 37 °C and 180 rpm, the degradation rate of beta-cypermethrin by GXzq was as high as 89.84% within 96 h, which exceeded that achieved by the single strains GXZQ4, GXZQ6, GXZQ7, and GXZQ13 and their derived microbial flora GXh.

    Full Text Available One of the essential analyses which is performed during the floristic study of a region is the analysis of the biological spectrum. The analysis of the biological spectrum of the flora includes the determination of the type of life form for each taxon described in the flora of the study region. If it is considered that life form is a specific structural-functional response to the environmental effects and the result of the adaptation during the species evolution, it is clear that the basic characteristics of the site are more or less reflected in any life form. This fact is confirmed by the analysis of the biological spectrum of Divčibare flora. The study results are in correlation with the results of the analysis of the biological spectrum of the flora of Serbia and the Balkan Peninsula.

    The gut micro flora plays vital role in health status of the host. The majority of microbes residing in the gut have a profound influence on human physiology and nutrition. Different human ethnic groups vary in genetic makeup as well as the environmental conditions they live in. The gut flora changes with genetic makeup and environmental factors and hence it is necessary to understand the composition of gut flora of different ethnic groups. Indian population is different in physiology from western population (YY paradox) and thus the gut flora in Indian population is likely to differ from the extensively studied gut flora in western population. In this study we have investigated the gut flora of two Indian families, each with three individuals belonging to successive generations and living under the same roof. Denaturation gradient gel electrophoresis analysis showed age-dependant variation in gut microflora amongst the individuals within a family. Different bacterial genera were dominant in the individual of varying age in clone library analysis. Obligate anaerobes isolated from individuals within a family showed age related differences in isolation pattern, with 27% (6 out of 22) of the isolates being potential novel species based on 16S rRNA gene sequence. In qPCR a consistent decrease in Firmicutes number and increase in Bacteroidetes number with increasing age was observed in our subjects, this pattern of change in Firmicutes / Bacteroidetes ratio with age is different than previously reported in European population. There is change in gut flora with age amongst the individuals within a family. The isolation of high percent of novel bacterial species and the pattern of change in Firmicutes /Bacteroidetes ratio with age suggests that the composition of gut flora in Indian individuals may be different than the western population. Thus, further extensive study is needed to define the gut flora in Indian population.

    Bacterial vaginosis (BV) is characterised by depletion of the normal Lactobacillus spp. and overgrowth of commensal anaerobic bacteria. We investigated the composition of vaginal microbiota and their association with BV in women of reproductive age. Vaginal samples from 1197 women were analysed, whereby n=451 patients had normal flora and n=614 were diagnosed with BV, the remaining patients were diagnosed with having either intermediate flora (n=42) or dysbacteriosis (n=90). The reported results show that pathogens are associated with BV. This knowledge will further expand our understanding of events leading to BV, which may lead to more effective prevention and treatment strategies.

    2017-09-01

    Full Text Available On the basis of the digital edition of the “Atlas of the vascular flora of the Pyrenees” (www.florapyrenaea. org, the alpine flora of this mountain range is delimited in order to know its diversity and the different patterns of its spatial distribution, along with some other environmental characteristics. The Pyrenean alpine flora is made up of 645 taxa (630 species and 15 subspecies. All the administrative regions harbour more than 60% of the alpine plants, with Catalonia and Aragon reaching the highest values (around 90%. Along the altitudinal gradient, the highest plant diversity is found between 2300 and 2600 m. a. s. l., although 25% of the total alpine flora goes beyond 3000 m. On the other hand, a remarkable number of alpine plants live in the lowlands, and thus more than 300 alpine plants can be found below 1500 m. The average altitude range of the alpine plants is 1369 m, 300 m wider than that observed for the whole Pyrenean flora. Life-forms, habitat distribution and habitat naturalness of alpine plants are significantly different from those of the whole Pyrenean flora. Distribution of abundance categories also shows values of rarity significantly lower among alpine plants than for the whole flora. More than half the Pyrenean endemic plants are present in the alpine flora. High diversity and wide ecological amplitude of the alpine flora must be taken into account either when considering vulnerability of alpine plants facing “global change” or when addressing conservation policies for the whole Pyrenees from a common perspective.

  5. Protein synthesis and intestinal flora in piglets

    1980-01-01

    Utilization of non-protein nitrogen (NPN) by the flora in piglet colon was studied by administration of 15 N-urea and 15 N-ammonium salt to aseptic piglets and to SPF piglets which had been acclimatized to a clean environment after settling of intestinal flora. Administration of 15 N-urea did not result in 15 N uptake by any tissue-constituting protein at any site of the aseptic piglets, almost all 15 N being excreted into the urine. In contrast, the tissue and skeletal muscle of the SPF piglets showed incorporated 15 N from urea. Urea was converted, by urease of the intestinal flora, into NH 3 , which was absorbed from the mucosa of the intestinal tract to reach the liver where it was synthesized into glutamic acid, followed by conversion into various amino acids. 15 N-ammonium administration produced a significant amount of 15 N even in the tissue protein of the aseptic piglets. After NPN administration, the liver protein-constituting amino acid fraction showed 15 N-labeling of almost all essential, as well as non-essential amino acids. Culture of colonic flora with 15 N-urea revealed 15 N-labeling of all amino acids that constituted bacterial cells, indicating the presence of urea recycling mediated by bacterial urease in single rumen animals.(Chiba, N.)

    Concerning the surrounding flora, the implementation of pipelines may cause fragmentation and isolation of the remaining natural vegetation, possibly changing the forest structure; thus raising the border effect; modifying the ratio of species and life forms, decreasing the vegetal diversity and/or causing a lack of connectivity among the remaining indigenous forest resources. In the case of pipelines, the most important environmental measure intended to mitigate the damage caused to the flora is the adoption of Indigenous Flora Rescue Programs. This paper is aimed at analyzing the programs currently applied during the implementation of the GASENE project, by conducting a case study. The main targets of such program are obtaining seeds and fruits with a view to subsidize the potential production of sapling to be further employed in the recovery of areas impacted by the pipeline works; and then relocate the most significant samples of species rescued from the suppressed areas in order to comprise forest areas adjacent to the pipeline's right-of-way. The programs had little differences in their methodology while being implemented, however, we consider that up to the present moment the results obtained in the preservation of species of native flora have been satisfactory.

    Studies have shown that not only bacterial vaginosis, but also intermediate vaginal flora has deleterious effects for women's reproductive health. However, literature still lacks information about microbiological and immunological aspects of intermediate flora. To characterize intermediate flora regarding levels of Interleukin (IL)-1beta, IL-6, IL-8, tumor necrosis factor-alpha, interleukin 1 receptor antagonist (IL-1ra), IL-10, sialidase; loads of Gardnerella vaginalis, total bacteria and to verify whether it is closer related to normal flora or bacterial vaginosis. This cross-sectional study enrolled 526 non-pregnant reproductive-aged women distributed in 3 groups according to pattern of vaginal flora using Nugent's system in normal, intermediate and bacterial vaginosis. Cervicovaginal levels of cytokines, sialidases, loads of G. vaginalis and total bacteria were assessed by ELISA, conversion of MUAN and quantitative real-time PCR, respectively. A principal component analysis(PCA) using all measured parameters was performed to compare the three different types of flora. Results showed that intermediate flora is associated with increased cervicovaginal IL-1beta in relation to normal flora(Pbacterial vaginosis, intermediate flora has higher IL-8 and IL-10 levels(Pbacterial vaginosis(Pbacterial differed among all groups(Pbacterial vaginosis. PCA showed that normal and intermediate flora were closely scattered, while bacterial vaginosis were grouped separately. Although intermediate flora shows some differences in cytokines, sialidases and bacterial loads in relation to normal flora and bacterial vaginosis, when taken together, general microbiological and immunological pattern pattern of intermediate flora resembles the normal flora.

  9. Optimise the microbial flora with milk and yoghurt to prevent disease.

    Pathogenic bacteria, which are temporary or permanent members of our microbial flora, cause or contribute to a wide range of human disease at all ages. Conditions include Alzheimer's disease, atherosclerosis, diabetes mellitus, obesity, cancer, autoimmunity and psychosis, amongst others. The mechanism of damage is inflammation which can be chronic or acute. An optimal microbial flora includes a wide range of pathogenic bacteria in low dose. This allows specific immunity to be developed and maintained with minimal inflammatory damage. Human milk has evolved to deliver an optimal microbial flora to the infant. Cow's milk has the potential, following appropriate fortification, to maintain an optimal human microbial flora throughout life. Yoghurt is a fermented milk product in which bacteria normally present in milk convert sugars to lactic acid. The acid suppresses the growth of pathogens in the oral cavity, oropharynx and oesophagus. Thus yoghurt can restore an optimal flora in these regions in the short term. Since bacteria are transported between epithelial surfaces, yoghurt will also optimise the flora elsewhere. The judicious use of milk and yogurt could prevent a high proportion of human disease.

    An experimental infection with echinostomatid miracidia in sympatric or 'local' vs. allopatric or 'away' snail combinations, as a model to examine parasite compatibility, was carried out. We employed Euparyphium albuferensis miracidia to infect Gyraulus chinensis snails, from three different natural parks: Albufera (Valencia, Spain); the Ebro Delta (Tarragona, Spain) and Coto de Doñana (Huelva, Spain). Insignificant differences between the three snail strains were noted for the infection rate and the rhythm of daily cercarial production. However, a significantly higher total cercarial production per snail, patent period and life span were observed in local snails. The different infection characteristics in the three G. chinensis strains considered reveal that E. albuferensis miracidia demonstrate local adaptation.

    The soil vulnerability determines the sensitivity of the soil after an accidental radioactive contamination due to Cs-137 and Sr-90. The Department de Impacto Ambiental de la Energia of CIEMAT is carrying out an assessment of the radiological vulnerability of the different Spanish soils found on the Iberian Peninsula. This requires the knowledge of the soil properties for the various types of existing soils. In order to achieve this aim, a bibliographical compilation of soil profiles has been made to characterize the different soil types and create a database of their properties. Depending on the year of publication and the type of documentary source, the information compiled from the available bibliography is very heterogeneous. Therefore, an important effort has been made to normalize and process the information prior to its incorporation to the database.

  14. Geographical constraints are stronger than invasion patterns for European urban floras.

    Directory of Open Access Journals (Sweden)

    Carlo Ricotta

    Full Text Available Understanding the mechanisms that affect invasion success of alien species is an important prerequisite for the effective management of present and future aliens. To gain insight into this matter we asked the following questions: Are the geographical patterns of species distributions in urban floras different for native compared with alien plant species? Does the introduction of alien species contribute to the homogenization of urban floras? We used a Mantel test on Jaccard dissimilarity matrices of 30 urban floras across the British Isles, Italy and central Europe to compare the spatial distribution of native species with four classes of alien species: archaeophytes, all neophytes, non-invasive neophytes, and invasive neophytes. Archaeophytes and neophytes are species that were introduced into Europe before and after 1500 AD, respectively. To analyze the homogenizing effect of alien species on the native urban floras, we tested for differences in the average dissimilarity of individual cities from their group centroid in ordination space. Our results show that the compositional patterns of native and alien species seem to respond to the same environmental drivers, such that all four classes of alien species were significantly related to native species across urban floras. In this framework, alien species may have an impact on biogeographic patterns of urban floras in ways that reflect their history of introduction and expansion: archaeophytes and invasive neophytes tended to homogenize, while non-invasive neophytes tended to differentiate urban floras.

  17. Vegetation and flora of short-rotation willow stands from a conservation viewpoint

    Gustafsson, L.

    1986-01-01

    The energy forests were studied using random 0.5 x 0.5 m quadrats in which cover for field- and bottom-layer species was recorded in a percentage scale. The data were analysed using various multivariate methods. The vegetation and flora of twelve coppices in southern Sweden were investigated. Also the succession during the establishment phase on a meadow on the west coast and on a peat bog in the east-central part of the country was studied. Moreover, the impact on fen vegetation downstream of an energy forest on a peat bog was investigated. The flora and vegetation of energy forests is dominated by common ruderal species like Cirsium arvense, Galeopsis tetrahit and Urtica dioica. Uncommon species from woodland and fen habitats are only occasionally found. The field layer of energy forests shows a clear seasonality with maximal cover in July. The species number and the composition of vegetation vary greatly between the coppices and is largely determined by the management system. Intense cultivation including fertilization and the use of herbicides depletes the flora. Long rotation times decrease both species diversity and the field-layer cover. Uncommon species are mostly found in old coppices, which also often have a rich spring flora. A change in flora and vegetation occurs when an energy forest is established. The change is great and the time needed for stabilization of the energy forest flora is long when the original flora is dissimilar to the coppice flora. Willow coppices can increase habitat diversity in regions dominated by coniferous forests or in large-scale agricultural areas. Structural heterogeneity of a stand promotes diversity of the flora. Such heterogeneity can be created if a stand is composed of a variety of willow clones, if it is harvested at intervals, contains gaps, open ditches and is surrounded by edge zones of various types.

    This study aimed to investigate the effects of erythropoiesis-stimulating agents (ESAs) on intestinal flora in peritoneal fibrosis. Twenty-four Wistar albino rats were divided into 3 groups as the control group, which received 0.9% saline (3 mL/d) intraperitoneally; the chlorhexidine gluconate (CH) group, which received 3 mL/d injections of 0.1% CH intraperitoneally, and the ESA group, which received 3 mL/d injections of 0.1% CH intraperitoneally and epoetin beta (3 doses of 20 IU/kg/wk) subcutaneously. On the 21st day, the rats were sacrificed and the visceral peritoneum samples were obtained from left liver bowel. Blood samples were obtained from abdominal aorta and intestinal flora samples were obtained from transverse colon. Histopathologically, the CH, ESA, and control groups had peritoneal thickness of 135.4 ± 22.2 µm, 48.6 ± 12.8 µm, and 6.0 ± 2.3 µm, respectively. Escherichia coli was the predominant bacterium in the intestinal flora in the control group. Significant changes in microbial composition of intestinal flora towards Proteus species and Enterobacter species was seen among the groups (P flora among these groups were significantly different (P flora by a clinically significant amount in experimental peritoneal fibrosis. We consider that ESAs achieve this via regulating intestinal peristaltism.

    To study the metabolic transformation of pumiloside by rat intestinal flora in vitro and identify its metabolites. Pumiloside was incubated in the rat intestinal flora in vitro. HPLC was used to monitor the metabolic process, and HPLC-Q-TOF-MS was used to identify the structures of biotransformation products. In vitro, pumiloside was easily metabolized by rat intestinal flora, and with the prolongation of metabolic time, pumiloside was transformed into several metabolites. Three metabolites were initially identified in this experiment. The study indicated that pumiloside could be extensively metabolized in the rat intestinal flora in vitro.

    The aim of the project was to compare flora and insect fauna of organic and conventional hedgerows, and to study whether the drift of herbicides into hedgerows alone or in combination with differences in fertiliser application may explain any differences. The project consequently consisted of two...... of the most important agricultural conditions having an effect on flora and insect fauna in different agricultural systems. In the experiment flora and insect fauna were studied for three years. In the hedgerows clear differences in the floral composition were found, with more plant species in hedgerows...... at organically grown fields that at conventionally grown fields, on both sandy and loamy soils. The insect fauna was correlated with the flora, but no clear differences were found between the two agricultural systems. Apart from the hedgerow flora, also the type of crop grown on the adjacent fields affected...

    Full Text Available Conjunctival flora refers to population of microorganisms that dwell within the eyes of healthy individuals and is important in maintaining a healthy ocular surface and normal conjunctival function. Conjunctival flora may be altered by a variety of factors that include age, immunosuppression and geography. Immune function is compromised in diabetes mellitus. The aim of the present study was to see the pattern of conjunctival bacterial flora in diabetic and non-diabetic patients. This cross sectional study was carried out in BSMMU during the period of January 2011 to December 2011. Total 500 conjunctival swabs were collected from both eyes of 50 diabetic patients attending OPD of Endocrinology Department of BSMMU and 200 non-diabetic individuals. Significant number of culture was positive in diabetic patients (64.0% compared to that of non-diabetic individuals (38.0%. Staphylococcus epidermidis was predominant in both study groups (diabetic vs non-diabetic: 41.3% vs 65.26%. Staphylococcus aureus (15.22%, Escherichia coli (6.52% and Enterobacter (8.33% were isolated in diabetic patients. Rate of positive culture in both and single eyes were higher in diabetic (28%, 36.0% than that of non-diabetic individuals (9.5%, 28.5%. Ibrahim Med. Coll. J. 2013; 7(1: 5-8

    Fire has had a profound effect on the evolution of worldwide biotas. The Cape Floristic Region is one of the world's most species-rich regions, yet it is highly prone to recurrent fires and fire-adapted species contribute strongly to the overall flora. It is hypothesized that the current fire regimes in the Cape could be as old as 6-8 million years (My), while indirect evidence indicates that the onset of fire could have reached 18 million years ago (Ma). Here, we trace the origin of fire-dependent traits in two monocot families that are significant elements in the fire-prone Cape flora. Our analysis shows that fire-stimulated flowering originated in the Cape Haemodoraceae 81 Ma, while fire-stimulated germination arose in the African Restionaceae at least 70 Ma, implying that wildfires have been a significant force in the evolution of the Cape flora at least 60 My earlier than previous estimates. Our results provide strong evidence for the presence of fire adaptations in the Cape from the Cretaceous, leading to the extraordinary persistence of a fire-adapted flora in this biodiversity hotspot, and giving support to the hypothesis that Cretaceous fire was a global phenomenon that shaped the evolution of terrestrial floras.

    Full Text Available Railway areas are considered as large greenspaces and are recognized important in improving the biodiversity and dynamic of urban flora. In this study, we examined the flora composition and diversity along intra-city railway lines in Lublin, SE Poland and Lviv, W Ukraine. The flora has been analyzed in terms of species composition (multivariate ordination techniques, life span, life form, type of pollination mode, seed dispersal, life strategy sensu Grime, hemerophoby, urbanity degree, and in terms of habitat preferences using ecological indicator values. The multivariate analysis (CCA clearly revealed that abiotic factors (topographical, weather elements (annual precipitation and air temperature, and soil attributes (moisture, trophy, pH, salinity differed between two cities and impacted on the differences in railway flora composition. Plants growing on the intra-urban railway areas are mainly hemicryptophytes/perennials, C, CR, CRS-strategists, insect-, self-, or wind-pollinated, reproducing by seeds and mainly dispersed by wind. Intra-urban railway areas are predominated by native species, however the participation of invasive alien species is higher than their proportion in domestic floras. The share of invasive species is greater in railway areas of Lviv, ca. 12% (45 species compared to 8% in Lublin (36 species. Spontaneous flora in intra-urban railway areas represent distinct adaptations to unique urban-industrial ecosystems with different degree of anthropogenic disturbance.

    Lactobacilli species that are better adapted to vaginal environment of women may colonize better and offer protection against vaginal pathogenic bacteria. In this study, the distribution of common Lactobacillus species was investigated in pregnant women. Sixty seven pregnant women were included in the study and vaginal samples were collected for Gram staining. Women were classified as normal vaginal flora, intermediate flora and bacterial vaginosis (BV) based on Nugent's score. Vaginal samples were also collected for the identification of Lactobacillus spp. by multiplex polymerase chain reaction (PCR) profiling of 16S rDNA amplification method. Lactobacillus crispatus (100%) was the most predominant Lactobacillus spp. present in pregnant women with normal flora, followed by L. iners (77%), L. jensenii (74%) and L. helveticus (60%). While, L. iners was commonly present across groups in women with normal, intermediate or BV flora, L. crispatus, L. jensenii and L. helveticus decreased significantly as the vaginal flora changed to intermediate and BV. In women with BV, except L. iners other species of lactobacilli was less frequently prevalent. Species such as L. rhamnosus, L. fermentum, L. paracasei and L. casei were not detected in any vaginal sample. L. crispatus, L. jensinii and L. helveticus were predominant species in women with normal flora. L. crispatus alone or in combination with L. jensinii and L. helveticus may be evaluated for probiotic properties for the prevention and treatment of BV.

    Element load, conventional biomarkers and altered protein expression profiles were studied in Carcinus maenas crabs, to assess contamination of 'Domingo Rubio' stream, an aquatic ecosystem that receives pyritic metals, industrial contaminants, and pesticides. Lower antioxidative activities - glucose-6-phosphate and 6-phosphogluconate dehydrogenases, catalase - were found in parallel to higher levels of damaged biomolecules - malondialdehyde, oxidized glutathione -, due to oxidative lesions promoted by contaminants, as the increased levels of essential - Zn, Cu, Co - and nonessential - Cr, Ni, Cd - elements. Utility of Proteomics to assess environmental quality was confirmed, especially after considering the six proteins identified by de novo sequencing through capLC-muESI-ITMS/MS and homology search on databases. They include tripartite motif-containing protein 11 and ATF7 transcription factor (upregulated), plus CBR-NHR-218 nuclear hormone receptor, two components of the ABC transporters and aldehyde dehydrogenase (downregulated). These proteins could be used as novel potential biomarkers of the deleterious effects of pollutants present in the area. - Pollution assessment at 'Domingo Rubio' stream (Spain).

  8. Floristic response to urbanization: Filtering of the bioregional flora in Indianapolis, Indiana, USA.

    2017-08-09

    Globally, urban plant populations are becoming increasingly important, as these plants play a vital role in ameliorating effects of ecosystem disturbance and climate change. Urban environments act as filters to bioregional flora, presenting survival challenges to spontaneous plants. Yet, because of the paucity of inventory data on plants in landscapes both before and after urbanization, few studies have directly investigated this effect of urbanization. We used historical, contemporary, and regional plant species inventories for Indianapolis, Indiana USA to evaluate how urbanization filters the bioregional flora based on species diversity, functional traits, and phylogenetic community structure. Approximately 60% of the current regional flora was represented in the Indianapolis flora, both historically and presently. Native species that survived over time were significantly different in growth form, life form, and dispersal and pollination modes than those that were extirpated. Phylogenetically, the historical flora represented a random sample of the regional flora, while the current urban flora represented a nonrandom sample. Both graminoid habit and abiotic pollination are significantly more phylogenetically conserved than expected. Our results likely reflect the shift from agricultural cover to built environment, coupled with the influence of human preference, in shaping the current urban flora of Indianapolis. Based on our analyses, the urban environment of Indianapolis does filter the bioregional species pool. To the extent that these filters are shared by other cities and operate similarly, we may see increasingly homogenized urban floras across regions, with concurrent loss of evolutionary information. © 2017 Dolan et al.

    Full Text Available The article expounds the experience of the restoration of the Walled Area of Niebla (Huelva for the Ministry of Culture. It is an Almohade fortification made of adobe walls of red earth and stone of the area, which was in a lamentable state of abandonment. The singularity of the intervention lies in the methods used for the project and the originality of the material to be restored, which because of its heterogeneousness, made obligatory the making of a new face between 25 and 150 cm of adobe walls of stabilized earth which was sewn to the old ones. The article is introduced through a series of considerations on earth architecture, and after a historical review of Niebla, describes the structure and documents of the project and also gives a description of the works carried out, explaining the details of the material (dosification: 3 parts of red earth, 2 of sand, 3 of minute gravel, 2 of calcium and 1 of cement; plasticity by organoleptical procedures, and the auxiliary means employed (boards of 90 cm to one face, waters not extracted, sewn bv mortisina and metallic legs. The structure of the article is superior to the usual presentation of a work in architectural magazines.

    The tropical climate in China exists in southeastern Xizang (Tibet), southwestern to southeastern Yunnan, southwestern Guangxi, southern Guangdon, southern Taiwan, and Hainan, and these southern Chinese areas contain tropical floras. I checked and synonymized native seed plants from these tropical areas in China and recognized 12,844 species of seed plants included in 2,181 genera and 227 families. In the tropical flora of southern China, the families are mainly distributed in tropical areas and extend into temperate zones and contribute to the majority of the taxa present. The genera with tropical distributions also make up the most of the total flora. In terms of geographical elements, the genera with tropical Asian distribution constitute the highest proportion, which implies tropical Asian or Indo-Malaysia affinity. Floristic composition and geographical elements are conspicuous from region to region due to different geological history and ecological environments, although floristic similarities from these regions are more than 90% and 64% at the family and generic levels, respectively, but lower than 50% at specific level. These differences in the regional floras could be influenced by historical events associated with the uplift of the Himalayas, such as the southeastward extrusion of the Indochina geoblock, clockwise rotation and southeastward movement of Lanping-Simao geoblock, and southeastward movement of Hainan Island. The similarity coefficients between the flora of southern China and those of Indochina countries are more than 96% and 80% at family and generic levels, indicating their close floristic affinity and inclusion in the same biogeographically floristic unit.

    We surveyed the flora of Oktibbeha County, Mississippi, U.S.A., from February 1994 to 1996. Occupying 118 square kilometers in east-central Mississippi, Oktibbeha County lies among 3 physiographic regions that include, from west to east, Interior Flatwoods, Pontotoc Ridge, and Black Prairie. Accordingly, the county harbors a diverse flora. Based on field work, as well as an extensive review of published literature and herbarium records at IBE and MISSA, we recorded a total of 1,148 taxa (1,125 species, 7 hybrids, 16 infraspecific taxa) belonging to 514 genera in 160 families, over 85% of all taxa documented were native. Compared to 3 other counties in east-central Mississippi, Oktibbeha County has the second largest recorded flora. The number of state-listed (endangered, threatened, or of special concern) taxa (67) documented in this survey far exceeds that reported from any other county in the region. Three introduced species, Ilex cornuta Lindl. & Paxton, Mahonia bealei (Fortune) Carrie??re, and Nandina domestica Thunb., are reported in a naturalized state for the first time from Mississippi. We also describe 16 different plant communities belonging to 5 broad habitat categories: bottomland forests, upland forests and prairies, aquatic habitats, seepage areas, and human-influenced habitats. A detailed description of the vegetation associated with each of these communities is provided.

    The archeology and history of the ancient Mediterranean have shown that this sea has been a permeable obstacle to human migration. Multiple cultural exchanges around the Mediterranean have taken place with presumably population admixtures. A gravitational territory of those migrations has been the Iberian Peninsula. Here we present a comprehensive analysis of the maternal gene pool, by means of control region sequencing and PCR-RFLP typing, of autochthonous Andalusians originating from the coastal provinces of Huelva and Granada, located respectively in the west and the east of the region. The mtDNA haplogroup composition of these two southern Spanish populations has revealed a wide spectrum of haplogroups from different geographical origins. The registered frequencies of Eurasian markers, together with the high incidence and diversification of African maternal lineages (15% of the total mitochondrial variability) among Huelva Andalusians when compared to its eastwards relatives of Granada and other Iberian populations, constitute relevant findings unknown up-to-date on the characteristics of mtDNA within Andalusia that testifies a female population substructure. Therefore, Andalusia must not be considered a single, unique population. The maternal legacy among Andalusians reflects distinctive local histories, pointing out the role of the westernmost territory of Peninsular Spain as a noticeable recipient of multiple and diverse human migrations. The obtained results underline the necessity of further research on genetic relationships in both sides of the western Mediterranean, using carefully collected samples from autochthonous individuals. Many studies have focused on recent North African gene flow towards Iberia, yet scientific attention should be now directed to thoroughly study the introduction of European genes in northwest Africa across the sea, in order to determine its magnitude, timescale and methods, and to compare them to those terrestrial movements

    The study on microbial populations is a suitable tool to understand and apply control methods to improve the sanitary level of production in fish breeding and rearing centers, ensure health of sturgeon fingerlings at the time of their release into the rivers and also in the conversation and restoration of these valuable stocks in the Caspian Sea, Iran. A laboratory research based on Austin methods (Austin, B., Austin, D.A. 1993) was conducted for bacterial study on 3 sturgeon species naming A. persicus, A. stellatus and A. nudiventris during different growth stages. Bacterial flora of Acinetobacter, Moraxella, Aeromonas, Vibrio, Edwardsiella, Staphylococcus, Proteus, Yersinia, Pseudomonas and Plesiomonas were determined. The factors which may induce changes in bacterial populations during different stages of fife are the followings: quality of water in rearing ponds, different conditions for growth stages, suitable time for colonization of bacterial flora in rearing pond, water temperature increase in fingerlings size and feeding condition.

OBJETIVO: conocer las actitudes, intereses, creencias, expectativas y vivencias de la comunidad educativa de la Escuela de Enfermería de la Universidad de Huelva respecto al desarrollo de los créditos de Libre Configuración. SUJETO Y MÉTODO: se realizaron entrevistas semiestructuradas y grupos de discusión a los sectores del alumnado, profesorado y cargos directivos. RESULTADOS PRINCIPALES: El análisis de los diferentes discursos sociales pone de manifiesto que el desarrollo de los créditos de Libre Configuración en el diseño curricular de Enfermería no cumple su misión formativa global, detectándose, por tanto, una fuerte contradicción entre la filosofía de la Libre Configuración y lo que realmente se lleva a la práctica. Los actores participantes en este proceso formativo lo viven como una carga curricular adicional con escaso valor educativo. CONCLUSIONES: La Libre Configuración no alcanza el objetivo de formación global que se pretendió al ser introducida en el currículo de Enfermería.

    The normal body exists in mutualistic balance with a large range of microbiota. The primary goal of this study was to establish whether there is an imbalance in the oropharyngeal flora early after hospital or ICU admittance, and whether flora differs between control, ward and critically ill patients. The secondary goal was to explore whether there are patient characteristics that can be associated with a disturbed oropharyngeal flora. Oropharyngeal cultures were obtained from three different study groups: (1) controls from the community, (2) ward patients and (3) critically ill patients, the two latter within 24 h after admittance. Cultures were obtained from 487 individuals: 77 controls, 193 ward patients and 217 critically ill patients. Abnormal pharyngeal flora was more frequent in critically ill and ward patients compared with controls (62.2% and 10.4% vs. 1.3%, P flora in the oropharynx was more frequent in critically ill patients compared with ward patients or controls (26.3% vs. 4.7% and 1.3%, P flora in the oropharynx in both ward and critically ill patients (P = 0.030 and P = 0.044, respectively). This study indicates that abnormal oropharyngeal flora is an early and frequent event in hospitalised patients and more so in the critically ill, compared to controls.

Varios factores permiten que se mantenga el equilibrio necesario para conservar la salud. Se ha descrito que una de las funciones más importantes de la flora normal es la resistencia que confi ere a la invasión por agentes patógenos a través de diversos mecanismos como es la producción de bacteriocinas, ácido láctico o peróxido de hidrógeno entre otros. Destacan los lactobacilos (Lactobacillus casei, L. acidophilus y L. bifidus, habitantes del tracto gastrointestinal y vaginal, que inhiben el crecimiento de bacterias y virus como Salmonella y el VIH respectivamente. Los probióticos son microorganismos vivos, no patógenos, los cuales administrados en cantidades adecuadas confieren un beneficio sobre la salud del huésped. La investigación de diversas bacterias resulta alentadora debido a su uso potencial para mantener y restaurar la flora normal lo cual puede ser benéfico para la nutrición, la prevención de enfermedades y en un futuro ser parte de un tratamiento integral. The microbiota is the group of microorganisms that live normally in different parts of the human body. Several factors allow the maintenance of the required equilibrium to preserve health. It has been described that one of the most important functions of the normal flora is the resistance they confer to humans against invasion by pathogenic agents by different mechanisms such as production of bacteriocins, lactic acid or hydrogen peroxide. Among the most noticeable microorganisms are lactobacilli (Lactobacillus casei, L. acidophilus and L. bifidus, inhabitants of gastrointestinal and genital tract which inhibit the growth of pathogenic bacteria and viruses such as Salmonella and VIH, respectively. Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. Research conducted with several

    Full Text Available The Taiwan vascular flora is exceptionally interesting not only because it is rich and diversified, but because it is of great phytogeographic significance owing to its geographic location. The flora of Taiwan, including naturalized plants, comprises 233 families and 1389 genera with 4216 species. In terms of major growth forms, there are 588 trees, 426 shrubs, 249 lianas, 177 vines, and 2776 herbs or ferns. Approximately 234 species are exotics typically associated with pastures, road clearings and other human disturbances. An extremely large percentage of these naturalized plants are of tropical New World origin. Among the native flora, the Orchidaceae (331 species, Gramineae (249, Compositae (194, Leguminosae (176, Cyperaceae (174, Rosaceae (105, Rubiaceae (93 and Euphorbiaceae (76 rank highest in numbers of species. Clearly, the greatest part of Taiwan's floristics richness comes from a wealth of species in primarily lowland (0–600 m asl. taxa. A total of 2571 species were recorded in the lowlands, whereas only about 251 species occur between 3100-3950 m. Endemic genera are extremely scarce in Taiwan, with only four, namely Sinopanax (Araliaceae, Hayatella (Rubiaceae, Kudoacanthus (Acanthaceae, and Haraella (Orchidaceae. In contrast to the low percentage of generic endemism, there is a remarkably higher specific endemism. About 1041 species (26.1% of indigenous plants are known only from Taiwan. A detailed examination of these species shows that there is a distinct trend of increasing endemism with increasing altitude (r² = 0.99. A survey of indigenous non-endemic species on the basis of their geographical distribution outside Taiwan shows that they can be classified into 6 major categories: 1. pantropical and palaeotropical species (1029 species; 2. species distributed in eastern Asia, from Himalayas through southern & eastern China to Taiwan, with some extending to the Ryukyus and Japan (1075 species; 3. widespread species extending

    This study aims to explore the effect of FMT on regulations of dysbacteriosis of pulmonary and intestinal flora in rats with 16S rDNA sequencing technology. A total of 27 SPF rats (3-4 weeks old) were randomly divided into three groups: normal control group (K), model control group (MX), and fecal microbiota transplantation group (FMT); each group contained nine rats. The OTU values of the pulmonary and intestinal flora of the MX group decreased significantly compared with the normal control group. After FMT, the OTU value of pulmonary flora increased, while the value of OTU in intestinal flora declined. At the phylum level, FMT down-regulated Proteobacteria , Firmicutes , and Bacteroidetes in the pulmonary flora. At the genus level, FMT down-regulated Pseudomonas , Sphingobium , Lactobacillus , Rhizobium , and Acinetobacter , thus maintaining the balance of the pulmonary flora. Moreover, FMT could change the structure and diversity of the pulmonary and intestinal flora by positively regulating the pulmonary flora and negatively regulating intestinal flora. This study may provide a scientific basis for FMT treatment of respiratory diseases.

    The vaginal microflora of a healthy asymptomatic woman consists of a wide variety of anaerobic and aerobic bacterial genera and species dominated by the facultative, microaerophilic, anaerobic genus Lactobacillus. The activity of Lactobacillus is essential to protect women from genital infections and to maintain the natural healthy balance of the vaginal flora. Increasing evidence associates abnormalities in vaginal flora during pregnancy with preterm labor and delivery with potential neonatal sequelae due to prematurity and poor perinatal outcome. Although this phenomenon is relatively common, even in populations of women at low risk for adverse events, the pathogenetic mechanism that leads to complications in pregnancy is still poorly understood. This review summarizes the current knowledge and uncertainties in defining alterations of vaginal flora in non-pregnant adult women and during pregnancy, and, in particular, investigates the issue of bacterial vaginosis and aerobic vaginitis. This could help specialists to identify women amenable to treatment during pregnancy leading to the possibility to reduce the preterm birth rate, preterm premature rupture of membranes, chorioamnionitis, neonatal, puerperal and maternal-fetal infectious diseases. Vaginal ecosystem study with the detection of pathogens is a key instrument in the prevention of preterm delivery, pPROM, chorioamnionitis, neonatal, puerperal and maternal-fetal infections.

Therefore, promoting their health, well-being, and psychosocial adaptation is a matter of strategic interest. This paper analyses psychosocial factors associated with well-being and psychological adjustment on a sample of 108 adolescents (55 males and 53 females, children of immigrants from Huelva (Spain and Algarve (Portugal, aged between 10 and 17 years. Adolescents were assessed for demographic characteristics and perceived well-being. We used the "KIDSCREEN-5", a self-report questionnaire that yields detailed profile information for children aged 8 to 18 years for the following ten dimensions: Physical well-being, Psychological well-being, Moods and emotions, Self-perception, Autonomy, Parental relationships and home life, Financial resources, Social support and peers, School environment, and Social acceptance (Bullying. Overall, significant differences were found between the Spanish and Portuguese samples on physical well-being, psychological well-being, mood, financial resources and social acceptance (bullying. Boys perceived themselves as having a better physical well-being than girls. Mothers' educational level was associated with psychological well-being and mood. Also, results suggested that residence location and other socio-demographical variables were not associated with the adolescents' well-being and psychological adjustment.

    Modern consumers are interested in the use of non-chemical methods to control pathogens when heat sterilization is not an option. Such is the case with teewurst sausage, a raw spreadable sausage and a popular German commodity. Although Listeria was not found in teewurst, the optimal microbial growing conditions of teewurst coupled with the ubiquity of L. monocytogenes in nature, makes the possibility of contamination of products very possible. This pilot study was conducted to examine teewurst's native micro-flora's ability to suppress the outgrowth of L. monocytogenes at 10 °C using standard plate counts and PCR-DGGE. Traditional plating methods showed L. monocytogenes growth significantly decreased when in competition with the teewurst's native micro-flora ( p flora of the teewurst suppressed the overall growth of L. monocytogenes by an average of two logs, under these conditions. Denaturing Gradient Gel Electrophoresis (DGGE) amplicons with unique banding patterns were extracted from DGGE gel for identification. Brochothrix thermosphacta and Lactobacillus curvatus were identified as a part of the teewurst's native micro-flora. Although the native micro-flora did not decrease L. monocytogenes to below limits of detection, it was enough of a decrease to warrant further investigation.

    Full Text Available Monitoring mine waste from sulfide deposits by hyperspectral remote sensing can be used to predict surface water quality by quantitatively estimating acid drainage and metal contamination on a yearly basis. In addition, analysis of the mineralogy of surface crusts rich in soluble salts can provide a record of annual humidity and temperature. In fact, temporal monitoring of salt efflorescence from mine wastes at a mine site in the Iberian Pyrite Belt (Huelva, Spain has been achieved using hyperspectral airborne Hymap data. Furthermore, climate variability estimates are possible based on oxidation stages derived from well-known sequences of minerals, by tracing sulfide oxidation intensity using archive spectral libraries. Thus, airborne and spaceborne hyperspectral remote sensing data can be used to provide a short-term record of climate change, and represent a useful set of tools for assessing environmental geoindicators in semi-arid areas. Spectral and geomorphological indicators can be monitored on a regular basis through image processing, supported by field and laboratory spectral data. In fact, hyperspectral image analysis is one of the methods selected by the Joint Research Centre of the European Community (Ispra, Italy to study abandoned mine sites, in order to assess the enforcement of the European Mine Waste Directive (2006/21/EC of the European Parliament and of the Council 15 March 2006 on the management of waste from extractive industries (Official Journal of the European Union, 11 April 2006.

    This study presents a new volatile organic compounds (VOC) dataset measured during the DOMINO field campaign in December 2008. The measurements were made from a 10m tower located in a nature reserve on the south west coast of Spain. For the analysis, the VOCs were collected and concentrated on a thermal desorber unit, separated on a gas chromotagraph equipped with an enantiomerically selective column, and detected by mass spectrometry. This experimental set-up allowed the measurement of anthropogenic VOCs such as ethyl benzene, and all xylene isomers, and biogenic species such as isoprene and monoterpenes. Here we examine the VOC mixing ratio variations as a function of air mass origin to characterize the measurement site in terms of biogenic and anthropogenic influences. Mixing ratios of biogenic species were generally low, consistent with the low winter season growth rates. The ratio of (-)-alpha-pinene to (+)-alpha-pinene was variable but showed a clear dominance of the (-)-enantiomer, similar to previous results obtained with the same system in the Tropical rainforest. High mixing ratios of benzene and toluene were related to transport events from Seville (to the northeast) and Huelva (to the west). The ratio of two short lived anthropogenic species ethylbenzene and meta-xylene was found to peak at midday and indicative of the levels of oxidant levels.

    Three biological expeditions was made from June 2003 to June 2004. Altitude is a major factor among the differences of flora and fauna distribution. Hkakaborazi (19296') is a reservoir of glaciers with permanent ice and snow from which rivers. Melikha and Maekha emanate. Ayeyarwaddy river formed from those two rivers and flow beside Myirkyina. Therefore, water quality of each river and their tributaries are cool and fresh. This quality can preserve endemic species. Unknown species of jellyfishes of Ayeyarwaddy river was collected from Myitkyina environ. Also, three different terrestrial habitats namely icy-mountain range, cool temperature and subtropical forest can conserve their characteristic flora and fauna. Flora and fauna distribution is always related to their habitat or environs. Diagnostic features of each species were recorded by photographs. The findings were discussed from conservation point of view.

    A relationship between type 2 diabetes mellitus (T2DM) and intestinal flora has been suggested since development of analysis technology for intestinal flora. An animal model of T2DM is important for investigation of T2DM. Although there are some animal models of T2DM, a comparison of the intestinal flora of healthy animals with that of T2DM animals has not yet been reported. The intestinal flora of Tsumura Suzuki Obese Diabetes (TSOD) mice was compared with that of Tsumura, Suzuki, Non Obesity (TSNO) mice in the present study. The TSOD mice showed typical type 2 diabetes symptoms, which were high-fat diet-independent. The TSOD and the TSNO mouse models were derived from the same strain, ddY. In this study, we compared the intestinal flora of TSOD mice with that if TSNO mice at 5 and 12 weeks of age. We determined that that the number of operational taxonomic units (OTUs) was significantly higher in the cecum of TSOD mice than in that of TSNO mice. The intestinal flora of the cecum and that of the feces were similar between the TSNO and the TSOD strains. The dominant bacteria in the cecum and feces were of the phyla Firmicutes and Bacteroidetes. However, the content of some bacterial species varied between the two strains. The percentage of Lactobacillus spp. within the general intestinal flora was higher in TSOD mice than in TSNO mice. In contrast, the percentages of order Bacteroidales and family Lachnospiraceae were higher in TSNO mice than in TSOD mice. Some species were observed only in TSOD mice, such as genera Turicibacter and SMB53 (family Clostridiaceae), the percentage of which were 3.8% and 2.0%, respectively. Although further analysis of the metabolism of the individual bacteria in the intestinal flora is essential, genera Turicibacter and SMB53 may be important for the abnormal metabolism of type 2 diabetes.

    Full Text Available Abstract Background Signature matching of nucleotide sequences in the V1 and V3 regions 16S rRNA genes using pyrosequencing technology is a powerful tool for typing vaginal Lactobacilli to the species level and has been used for investigating the vaginal microbial niche. Methods This study has characterized the normal cultivable vaginal Lactobacillus flora at varying estradiol levels in plasma; the study comprised 17 patients undergoing ovarian stimulation for In Vitro Fertilization (IVF treatment. The vaginal status of each participant was initially assessed as normal according to Amsel and Nugent criteria. Results L. crispatus, L. gasseri and/or L. jensenii were present in 10 of the patients throughout the study period, and little variation among these three species was encountered in individual patients. The flora of three women was dominated by L. delbrüeckii, L. rhamnosus or L. vaginalis. One woman exhibited a dominance of L. iners. The flora of the remaining three women were initially dominated by L. rhamnosus or L. reuteri, but as their estrogen levels rose, their flora composition altered, to become dominated by one of the three species most common in a normal, healthy vagina. Conclusion Signature matching of nucleotide sequences in the V1 and V3 regions of 16S rRNA genes is a discriminative tool for the study of vaginal Lactobacilli and can be used to track the Lactobacillus flora under a variety of physiological conditions.

    Full Text Available El presente trabajo surge de la necesidad de aproximarnos al conocimiento de la realidad concreta de la práctica psicomotriz en Educación Especial y Educación Infantil en la provincia de Huelva, a partir de las opiniones manifestadas por los profesores que trabajan en estas etapas educativas. Después de un siglo de existencia, tenemos mucha documentación sobre psicomotricidad, sus metodologías, sus contenidos, sus ámbitos de intervención y evaluación, pero poco sabemos sobre opiniones de los profesores, sobre la formación que dicen poseer estos enseñantes, que son los encargados de llevar a cabo proyectos psicomotores en los centros educativos. Es por ello que hemos sentido la necesidad de recoger información sobre la formación que dicen poseer los maestros de Educación Infantil y de Educación Especial de la provincia de Huelva.

In this setting, in recent years, there has been an exponential rise in the number of bariatric procedures, with approximately half of them performed in women of childbearing age, and a remarkable surge in the number of women who become pregnant after having undergone bariatric surgery (BS. These procedures entail the risk of nutritional deficiencies, and nutrition is a crucial aspect during pregnancy. Therefore, knowledge and awareness of the consequences of these techniques on maternal and fetal outcomes is essential. Current evidence suggests a better overall obstetric outcome after BS, in comparison to morbid obese women managed conservatively, with a reduction in the prevalence of gestational diabetes mellitus, pregnancy-associated hypertensive disorders, macrosomia, and congenital defects. However, the risk of potential maternal nutritional deficiencies and newborns small for gestational age cannot be overlooked. Results concerning the incidence of preterm delivery and the number of C-sections are less consistent. In this paper, we review the updated evidence regarding the impact of BS on pregnancy.

  16. The flora of Early Permian coal measures from the Parana Basin in Brazil: A review

    International Nuclear Information System (INIS)

    Iannuzzi, Roberto

    2010-01-01

    This paper presents an updated overview integrating both previous and newly published data on the most important floras found associated with Early Permian coal seams in the Parana Basin, Brazil. These floras occur within the Rio Bonito Formation and correspond to the Gondwana ''Glossopteris Flora.'' For this review, five floras are selected, in ascending stratigraphic order: the ''Sao Joao do Triunfo,'' ''Figueira,'' ''Quiteria,'' ''Morro do Papaleo'' and ''Irapua Bed'' floras. They are the best-known floras of the basin in terms of taxonomic composition, paleoecology and environments of deposition. An early-mid Sakmarian to earliest Artinskian age is indicated for the Rio Bonito Formation based on absolute radiometric and relative biostratigraphic ages. Integration of available information about the selected floras allows evaluation of taphonomic and paleoecological factors to provide a more comprehensive understanding of the Early Permian floral record in the Parana Basin. The variation observed in both the taxonomic composition of individual floras and in the frequency of occurrence of different plant groups is due to the broad range of environmental/edaphic conditions that prevailed in the many different depositional settings represented in the Rio Bonito Formation. A more precise age determination obtained for the plant-bearing deposits permits the establishment of a more confident correlation between the Early Permian floral succession in the Parana Basin and other Early Permian floral successions in other basins. The Sakmarian global warming favored the appearance of pecopterid and sphenopterid ferns amongst the spore-producing plants, and the glossopterids amongst the pollen-producing plants. (author)

    The microbiota of both humans and animals plays an important role in their health and the development of disease. Therefore, the bacterial flora of the conjunctiva may also be associated with some diseases. However, there are no reports on the alteration of bacterial flora in conjunctiva of diabetic rats in the literature. Therefore, we investigated the changes in bacterial flora in bulbar conjunctiva of rats with streptozotocin (STZ)-induced type I diabetes. A high dose of STZ (60 mg/kg, i.p.) was injected into Sprague-Dawley (SD) rats to induce type I diabetes mellitus (T1DM). The diabetic rats were raised in the animal laboratory and at 8 months post-injection of STZ swab samples were taken from the bulbar conjunctiva for cultivation of aerobic bacteria. The bacterial isolates were identified by Gram staining and biochemical features. The identified bacteria from both diabetic and healthy rats were then compared. The diabetic and healthy rats had different bacterial flora present in their bulbar conjunctiva. In total, 10 and 8 bacterial species were found in the STZ and control groups, respectively, with only three species (Enterococcus faecium, Enterococcus gallinarum and Escherichia coli) shared between the two groups. Gram-positive bacteria were common in both groups and the most abundant was Enterococcus faecium. However, after the development of T1DM, the bacterial flora in the rat bulbar conjunctiva changed considerably, with a reduced complexity evident. STZ-induced diabetes caused alterations of bacterial flora in the bulbar conjunctiva in rats, with some bacterial species disappearing and others emerging. Our results indicate that the conjunctival bacterial flora in diabetic humans should be surveyed for potential diagnostic markers or countermeasures to prevent eye infections in T1DM patients.

    Full Text Available One of the essential analyses performed during the floristic study of a region is the analysis of the biological spectrum. The analysis of the biological spectrum of the flora includes the determination of the type of life form for each taxon described in the flora of the study region. If it is considered that life form is a specific structural-functional response to the environmental effects and the result of the adaptation during the species evolution, it is clear that the basic characteristics of the site are more or less reflected in any life form. This fact is confirmed by the analysis of the biological spectrum of the flora of Ravni Srem. The analysis of the Ravni Srem flora shows the domination of the hemicryptophytes and the subdomination of the phanerophytes with a considerable participation of the therophytes.

    The aim of this study was to evaluate changes in nasal and oropharyngeal flora in patients with acne during treatments with tetracycline and isotretinoin. Swab specimens were taken from the right and left nasal cavities and oropharynx of 55 patients with acne and 20 healthy volunteers who were admitted to the dermatology department (Etlik Educational and Research Hospital, Ankara, Turkey) before the administration of treatment and in the third month of treatment. Study participants were divided into four groups as follows: patients with acne on topical treatment only, systemic isotretinoin, and systemic tetracycline, and the control group. Of 55 patients with acne, 18 were male and 37 were female. The mean age of the patients and the control group was 22.21 ± 4.22 and 21.95 ± 7.64, respectively. Staphylococcus aureus was isolated from the nasal flora of five patients, normal flora was suppressed in the oropharyngeal cultures of seven patients, and normal flora grew in the cultures of the other 20 patients who were on tetracycline treatment. On the other hand, normal flora grew in the nasal and oropharyngeal cultures of all the patients who were on isotretinoin treatment. Treatment options and follow-up procedures for acne vulgaris may lead to the development of bacterial resistance and damage to flora. In particular, systemic tetracycline treatment leads to changes in flora of the nose and throat in patients with acne with an increased carriage of S. aureus. Therefore, careful attention should be paid to the duration of tetracycline treatment in order to not increase the risk of disturbance of microbial flora. © 2014 The International Society of Dermatology.

    This paper reports on nuclear export activities in Spain, as elsewhere, which occur in a political, economic, and technological context. The factors operating the process are not always explicitly related in the public and the private sectors, nor between these sectors, by the relevant decision makers. A redefinition of Spain's policies in the nuclear sector has been going on since at least 1984, when a new energy plan was legislated by the newly elected Socialist government. It would be accurate to suggest that this process remains dynamic and not fully completed for policy purposes. This condition has resulted from the fact that Spain underwent a crucial political regime change from dictatorship to parliamentary democracy about a decade ago, with the transition to democracy only recently consolidated. Moreover, no policy in regard to nuclear nonproliferation existed during the Franco regime. Instead, Spain's official position was to maintain the right to preserve a nuclear option for national defense. However, this option was not developed into a concerted program to develop a nuclear military capability

  7. The intestinal flora is required to support antibody responses to systemic immunization in infant and germ free mice.

    2011-01-01

    The presence of a complex and diverse intestinal flora is functionally important for regulating intestinal mucosal immune responses. However, the extent to which a balanced intestinal flora regulates systemic immune responses is still being defined. In order to specifically examine whether the acquisition of a less complex flora influences responses to immunization in the pre-weaning stages of life, we utilize a model in which infant mice acquire an intestinal flora from their mothers that has been altered by broad-spectrum antibiotics. In this model, pregnant dams are treated with a cocktail of antibiotics that alters both the density and microbial diversity of the intestinal flora. After challenge with a subcutaneous immunization, the antibiotic altered flora infant mice have lower antigen specific antibody titers compared to control age-matched mice. In a second model, we examined germ free (GF) mice to analyze how the complete lack of flora influences the ability to mount normal antibody responses following subcutaneous immunization. GF mice do not respond well to immunization and introduction of a normal flora into GF mice restores the capacity of these mice to respond. These results indicate that a gastrointestinal flora reduced in density and complexity at critical time points during development adversely impacts immune responses to systemic antigens.

  8. Early stages of formation and dispersal of the temperate flora in the Boreal region

    1992-01-01

    The thesis of this review is that the composition of a flora can be understood only as a process, or separate stage, in the context of migration in time and space of various floristic assemblages and their isolation, as induced by transformation of continental and ocean shapes, changes in climate, and the environment as a whole. Thus the formation of geofloras of the past was influenced by gradually changing environments that determined the spread, patterning, and spatial differentiation of floras and their evolution. Parallel to the more commonly-seen names of eras-Paleozoic, Mesozoic, and Cenozoic-we can speak of the Paleophytic, Mesophytic, and Cenophytic eras. Eras defined in these two ways (by faunistic or by floristic criteria) do not completely coincide. Generally, changes in the flora have, necessarily, preceded changes in the fauna. It is the Cenophytic with which this review is mostly concerned, the era of Angiosperm dominance. The movement of early subtropical and warm temperate floras in the Early Cenophytic, followed by temperate or even boreal floras, as the climate changes, is traced in detail

The reserve is adjacent to the Fish River and some 5 km from the Fish River Mouth It consists of a coastal plateau up to 100 m a.s.I. which is steeply dissected by the two rivers that partially form the boundary of the reserve. The flora of the reserve was sampled over a period o f three years and plants were collected in all the vegetation types of grassland, thicket and forest. 488 species were collected with a species to family ratio of 4:4. The majority of the taxa recorded represent the major phytochoria of the region. Nineteen species are endemic to the Eastern Cape, two are classed as vulnerable, five are rare, six are protected and a further seventeen are of uncertain status. The flora of the Kap River has closest affinities to that of the Alexandria Forest.

    Full Text Available The flora of a region is important in aesthetic, environmental and economic terms. Academic degree holders are fundamental for the sustainable development of a geographically isolated region such as the Azores, the University of Azores (UAc contributing to that goal. We assessed the perception of the UAc students about the origin and the importance of the Azorean flora for conservation, culture and economy, by applying a questionnaire to 309 students in different scientific areas, addressing origin, symbolic importance, economic importance, and environmental functions. Students showed some knowledge about the concepts of endemic, native, introduced and invasive species, but often failed to connect those to specific plant taxa. Most species cited as symbolic were animals, and the plants mentioned were mainly exotic/invasive. Respondents had a sense of the most important crops and forest species, and attributed several functions related to biodiversity and environmental conservation to the flora. Despite the many actions already implemented, more initiatives are required to increase the connection between Azoreans and Azorean flora.

    Full Text Available Until recently, talk about tourism in the province of Huelva was to do exclusively with the coastal areas. Even today, and for a long time, these areas will continue hoarding the bulk of demand and equipment, based on the binomial “sun and sand”. However, in recent years the interior spaces are approaching the new demand for tourism, offering a rural landscape, an environment and a different cultural and historical heritage to you coastal tourist areas. A little beyond this issue, industrial and mining areas, sunk into crisis ore production system, today found a new path for development in the value enhancement of industrial mining heritage. One such area is the Andévalo Western mining, where mining has been one of the pillars upon which traditionally has built its economy, which has marked its evolution through the centuries. The development of the municipalities located in this region has been based essentially on short-term exploitation of natural resources, almost exclusively from metal mining.

    Full Text Available In order to improve the bioleaching efficiency of arsenic-rich gold concentrates, a mixed bacterial flora had been developed, and the mutation breeding method was adopted to conduct the research. The original mixed bacterial flora had been enrichedin acid mine drainage of Dexing copper mine, Jiangxi Province, China. It was induced by UV (ultraviolet, ultrasonic, and microwave, and their combination mutation. The most efficient bacterial flora after mutation was collected for further bioleaching of arsenic-rich gold concentrates. Results indicated that the bacterial flora after mutation by UV 60 s combined with ultrasonic 10 min had the best oxidation rate of ferrous, the biggest density of cells, and the most activity of total protein. During bioleaching of arsenic-rich gold concentrates, the density of the mutant bacterial cells reached to 1.13×108 cells/mL at 15 days, more than 10 times compared with that of the original culture. The extraction of iron reached to 95.7% after 15 days, increased by 9.9% compared with that of the original culture. The extraction of arsenic reached to 92.6% after 12 days, which was increased by 46.1%. These results suggested that optimum combined mutation could improve leaching ability of the bacterial flora more significantly.

    2011-01-01

    Highlights: → Huelva estuary is affected by former phosphogypsum releases and pyrite acid mine drainage. → Time evolution of uranium concentration is analyzed after halting of NORM releases. → Two new contamination sources are preventing the complete uranium cleaning: (1) The leaching of phosphogypsum stacks located close to Tinto River. (2) Pyrite acid mine drainage. → High uranium concentrations are dissolved in water and precipitate subsequently. - Abstract: After the termination of phosphogypsum discharges to the Huelva estuary (SW Spain), a unique opportunity was presented to study the response of a contaminated environmental compartment after the cessation of its main source of pollution. The evolution over time of uranium concentrations in the estuary is presented to supply new insights into the decontamination of a scenario affected by Naturally Occurring Radioactive Material (NORM) discharges. The cleaning of uranium isotopes from the area has not taken place as rapidly as expected due to leaching from phosphogypsum stacks. An in-depth study using various techniques of analysis, including 234 U/ 238 U and 230 Th/ 232 Th ratios and the decreasing rates of the uranium concentration, enabled a second source of uranium contamination to be discovered. Increased uranium levels due to acid mine drainage from pyrite mines located in the Iberian Pyrite Belt (SW Spain) prevent complete uranium decontamination and, therefore, result in levels nearly twice those of natural background levels.

    2007-02-01

    DNA fingerprinting for inflammatory bowel disease (IBD) patients and healthy subjects was carried out to compare the difference of intestinal flora between the two groups. DNA fingerprinting for IBD patients and healthy persons was set up with enterobacterial repetitive intergenic consensus (ERIC-PCR) technology and the difference of intestinal flora between the two groups compared. DNA fingerprinting of the IBD patients and healthy subjects was identified and a significant difference was noticed between them. There were lots of bands in the DNA fingerprinting of the healthy subjects but few in that of the IBD patients. Strikingly, same distribution of the principal band of DNA fingerprinting was noticed in IBD patients. The variety of intestinal flora in healthy subjects is more apparent than that in IBD patients. An unique principal band might be the sequence of the presence of specific etiopathogenetic bacterium, or it might be the combined sequence of mixed bacterial flora.

    To investigate the changes in fecal flora and its correlation with the occurrence and progression of inflammatory bowel disease (IBD). We collected fresh fecal specimens from 167 IBD patients (including 113 with ulcerative colitis and 54 with Crohn's disease) and 54 healthy volunteers. The fecal flora was analyzed by gradient dilution method and the data of inflammatory markers including WBC, PLT, CRP and ESR were collected to assess the association between the fecal flora and the inflammatory markers. The species Enterrococcus (6.60∓0.23, Pflora. The changes in fecal flora did not show a significant correlation with these inflammatory markers. IBD patients have fecal flora imbalance compared with the healthy controls, and this imbalance may contribute to the occurrence and progression of IBD. The decline of Eubacterium contributes to the occurrence and development of IBD.

    High species diversity may result from recent rapid speciation in a ‘cradle’ and/or the gradual accumulation and preservation of species over time in a ‘museum’. China harbours nearly 10% of angiosperm species worldwide and has long been considered as both a museum, owing to the presence of many species with hypothesized ancient origins, and a cradle, as many lineages have originated as recent topographic changes and climatic shifts—such as the formation of the Qinghai-Tibetan Plateau and the development of the monsoon—provided new habitats that promoted remarkable radiation. However, no detailed phylogenetic study has addressed when and how the major components of the Chinese angiosperm flora assembled to form the present-day vegetation. Here we investigate the spatio-temporal divergence patterns of the Chinese flora using a dated phylogeny of 92% of the angiosperm genera for the region, a nearly complete species-level tree comprising 26,978 species and detailed spatial distribution data. We found that 66% of the angiosperm genera in China did not originate until early in the Miocene epoch (23 million years ago (Mya)). The flora of eastern China bears a signature of older divergence (mean divergence times of 22.04-25.39 Mya), phylogenetic overdispersion (spatial co-occurrence of distant relatives) and higher phylogenetic diversity. In western China, the flora shows more recent divergence (mean divergence times of 15.29-18.86 Mya), pronounced phylogenetic clustering (co-occurrence of close relatives) and lower phylogenetic diversity. Analyses of species-level phylogenetic diversity using simulated branch lengths yielded results similar to genus-level patterns. Our analyses indicate that eastern China represents a floristic museum, and western China an evolutionary cradle, for herbaceous genera; eastern China has served as both a museum and a cradle for woody genera. These results identify areas of high species richness and phylogenetic diversity, and

    Full Text Available Comprising an area of ± 90 000 km:, less than 5% of the land surface of the southern African subcontinent, the Cape Floristic Region (CFR is one of the world’s richest areas for plant species diversity. A recent synoptic flora for the Region has established a new base line for an accurate assessment of the flora. Here we document corrections and additions to the flora at family, genus and species ranks. As treated in Cape plants, which was completed in 1999. the flora comprised 173 families (five endemic, 988 genera (160 endemic: 16.2%, and 9 004 species (6 192 endemic: 68.8%. Just four years later, a revised count resulting from changes in the circumscriptions of families and genera, and the discovery of new species or range extensions of species, yields an estimate of 172 families (four endemic, 992 genera (162 endemic: 16.3% and 9 086 species (6 226: 68.5% endemic. Of these, 948 genera and 8 971 species are seed plants. The number of species packed into so small an area is remarkable for the temperate zone and compares favourably with species richness for areas of compa­rable size in the wet tropics. The degree of endemism is also remarkable for a continental area. An unusual family compo­sition includes, in descending order of size, based on species number. Asteraceae. Fabaceae. Iridaceae. Ericaceae. Aizoaceae, Scrophulariaceae. Proteaceae. Restionaceae, Rutaceae. and Orchidaceae. Disproportionate radiation has resulted in 59.1% of the species falling in the 10 largest families and 74.6% in the largest 20 families. Thirteen genera have more than 100 species and the 20 largest genera contribute some 31.5% of the total species number.

    The aim was to identify conjunctival bacterial and fungal flora in clinically normal sheep. Prospective study. Tuscany. 100 eyes from 50 adult Massese female sheep were examined. The sheep included in the study were considered free of anterior ophthalmic abnormalities. Bacteria were identified by morphological assessment, Gram staining, biochemical tests. Identification of filamentous fungi was achieved at the genus level, and Aspergillus species were identified based on keys provided by other authors. Yeast colonies were highlighted, but not identified. Positive cultures were obtained from 100/100 eyes for bacteria, and from 86/100 eyes for fungi. A total of 14 types of bacteria and 5 types of fungi were isolated. Yeasts were isolated from 13/100 eyes. The most frequent fungal isolates were saprophytic fungi. Conjunctival bacterial and fungal flora of clinically normal eyes were reported in sheep. The positivity obtained for conjunctival bacteria was higher compared to findings in the literature by other authors in the same species (100 per cent v 40 per cent), while our results were in line with a recent work performed on mouflons (Ovis Musimon) with a 100 per cent positivity for bacterial conjunctival fornix. In our survey, Gram-positive species were prevalent, as reported by other authors in different species. Few data are available in the literature regarding conjunctival fungal flora in healthy small ruminants. The prevalence of conjunctival fungal flora in this study was higher than findings reported in mouflons (86 per cent v 45 per cent). Differences in fungal prevalence may be due to different methods of managing herds, though further studies are required to verify this hypothesis. The similarities in bacterial and fungal isolates between sheep and mouflons suggest a genera pattern of conjunctival colonisation by bacteria and fungi.

    Envenomation causes an estimated 1.8-2.5 million incidences per year with a mortality level of 100-125,000 persons annually and more than 100,000 individuals suffer from severe complications, which may end in amputation of the attacked limb. The use of plants is a major part of the traditional practitioners' treatment of snakebites. A database was created for plants used to treat snakebites worldwide. From this database, we selected five countries with a high number of entries and representing different cultures, geography and floristic zones: Brazil, Nicaragua, Nepal, China and South Africa. The datasets were analysed by regression and binominal analysis to see if any family or genus used against snakebites was overrepresented in the respective traditional medicinal systems relative to the abundance in the local flora. The families from the different geographical areas were compared to ascertain whether the same plant families are preferred by different peoples. Three 'hot' families (Apocynaceae, Lamiaceae and Rubiaceae) were recovered in at least two of the five compared countries in the regression analyses and one 'hot' family (Zingiberaceae) was recovered in two of the compared countries in the binomial analyses. Four out of five floras possess families identified as outliers in both regression and binomial analyses. Eight families were recovered by both the binomial and the regression analysis (40-62% of all highlighted families respectively). At the genus level, only Piper (Piperaceae) was recovered as a 'hot' genus in at least two floras. Seven genera were highlighted by both analyses (25-44% of the highlighted genera). Cross-cultural comparison of medicinal floras used against snakebites appears to be useful for highlighting candidate families and genera for further studies. Copyright © 2012 Elsevier Ireland Ltd.

    Full Text Available The aim of our research is to study the endemics of the xerophilous flora of the Russian Caucasus in connection with the matter of knowing the genesis.Methods. The study is based on the field research expeditions.Findings. The presence of endemic species in flora is an indicator of its originality, and the degree of originality is determined by the extent of the endemic species. In general, according to our geographic analysis, the number of endemic species in xerophilous flora of the Russian Caucasus accounts for 32% (326 species, of which 25% of all endemic species have natural habitats within entire Caucasus, 66% are widespread in the Greater Caucasus, and 9% in the Pre-Caucasian region.Conclusion. Endemic species of xerophytes of the flora, in their overwhelming majority, are euxerophytes, and most steno-endemics also belong to this group of xerophytes. In a systematic aspect, the leading family, containing the largest number of endemic species, is Asteraceae (in percentage terms - Lamiaceae and Jurinea is a leading genus (in percentage terms - Psephellus. In relation to the substrate, calcixerophytes are the dominants and most saturated endemics in quantitative terms are the belt of mountain xerophytes. The predominant biomes are hemicryptophytes; as compared with the number of biomorphes, among chamaephytes there is the biggest quantity of endemics.

    Full Text Available Objective: To study the evaluation value of intestinal flora detection for intestinal mucosal inflammatory response and immune response in patients with ulcerative colitis. Methods: The patients who were diagnosed with ulcerative colitis in Zigong Fifth People’s Hospital between March 2015 and February 2017 were selected as the UC group, and those who were diagnosed with colonic polyps were selected as the control group. Fresh excreta were collected to detect the number of intestinal flora, and the diseased intestinal mucosa tissue was collected to detect the expression of inflammatory response molecules and immune cell transcription factors. Results: enterococcus contents in intestinal tract and TLR4, NF-kB, TNF-α, HMGB-1, T-bet and RORC mRNA expression levels in intestinal mucosa of UC group were significantly higher than those of control group while bifidobacteria contents in intestinal tract and SOCS2, SOCS3, Foxp3 and GATA-3 mRNA expression levels were significantly lower than those of control group; TLR4, NF-kB, TNF-α, HMGB-1, T-bet and RORC mRNA expression levels in intestinal mucosa of UC patients with grade II and grade III flora disturbance were significantly higher than those of UC patients with normal flora and grade I flora disturbance while SOCS2, SOCS3, Foxp3 and GATA-3 mRNA expression levels were significantly lower than those of UC patients with normal flora and grade I flora disturbance; TLR4, NF-kB, TNF-α, HMGB-1, T-bet and RORC mRNA expression levels in intestinal mucosa of UC patients with grade III flora disturbance were significantly higher than those of UC patients with grade II flora disturbance while SOCS2, SOCS3, Foxp3 and GATA-3 mRNA expression levels were significantly lower than those of UC patients with grade II flora disturbance. Conclusion: The intestinal flora disturbance in patients with ulcerative colitis can result in inflammatory response activation and immune response disorder.

    The levonorgestrel intrauterine system (LNG-IUS) combines a uterine foreign body and the continuous release of low-dose levonorgestrel for contraception. Its influence on the rate of vulvovaginal infections and flora disturbance is insufficiently known, but important for contraceptive advice in women, especially those who develop recurrent vaginosis or Candida vulvovaginitis. Slides of 286 women who had a Pap smear taken before and 1 to 2 years after placement of a LNG-IUS were blindly reviewed for the presence of abnormal vaginal flora (AVF), bacterial vaginosis (BV), aerobic vaginitis (AV) and Candida vaginitis (CV). Prior to insertion, there were no differences in vaginal flora abnormalities between women using different kinds of contraception. LNG-IUS users did not have different rates of AVF, BV, AV or CV, but the general risk to develop any infection was increased. Uterine bleeding after insertion did not seem to predict a different flora type. We found that Pap smears suggested more vaginal infections after 1 year of LNG-IUS use than prior to insertion of the device. Copyright © 2011 Elsevier Inc. All rights reserved.

    health situation of immigrant workers in Spain through key informants. Method: We performed a qualitative, exploratory and descriptive study using indepth interviews carried out in 2006. Organizations and associations working with immigrant collectives in Alicante, Barcelona, Huelva, Madrid and Valencia were identified and the most representative and accessible entities in each location were selected. Fortythree interviews were performed with key informants from 34 different organisms. A narrative content analysis was performed. Results: Informants described difficulties in having health problems recognized as workrelated, due to irregular and precarious employment, employers' and insurance companies' reluctance, and immigrants' lack of knowledge. Informants coincided in reporting that the occupational risks for immigrant workers did not differ from those affecting Spanish workers in the same occupations and circumstances. However, exposure to occupational risks was exacerbated in immigrants because of their greater presence in unqualified jobs and their economic need to prolong working hours. Immigrants had little knowledge of their occupational health and safetyrelated rights, although some informants detected an increase in empowerment in this area, mostly through greater participation in trade unions. Conclusions: This first step allowed us to identify some of the general factors influencing the health and safety of immigrant workers in Spain. This information will be used in a longterm, ongoing research project [Project Immigration, Work and Health (Proyecto Inmigración, Trabajo y Salud [ITSAL], which aims to evaluate occupational health problems in inmigrants working in Spain through both qualitative and quantitative methods.

    Full Text Available Algae have always been the most diverse and numerous eukaryotic autotrophs in marine ecosystems. Both fossil andmolecular data point to an early Proterozoic origin for algae. Although known for their long evolutionary history, the fossil recordof algae is sparse and mainly remains of taxa with heavily calcified thalli are preserved. However, fossils of noncalcareous algae,known as extremely sporadic and occasional finds from different parts of the world, provide important insights into thepalaeobiology of algal flora in the Earth's past. Here we describe highly diverse flora of noncalcareous thallophytic algae from aSilurian age deposit.

    Historically, Spain's nuclear program has had its share of successes and challenges. The country currently operates nine nuclear reactors totalling over 7,100 MWe of capacity and accounting for more than a third of Spain's electricity generation. Yet four reactors at advanced stages of construction remain mothballed due to a government-imposed moratorium, and a fire at one reactor in 1989 led to its premature closure and to a revival of anti-nuclear sentiment in the country. In the new national energy plan, Spain opted to continue the moratorium and rely upon conservation measures, additional natural gas imports, and electricity imports to meet expected demand. The current nuclear facilities will continue to operate, and the government will continue to pursue advanced reactor research, and expansion of the country's domestic uranium industry. Spain's integration into the European Community also is affecting the country's energy plans, prompting consolidation within the Spanish electricity sector in order to be more competitive in Europe

    Full Text Available Lichen is a symbiotic plant built by the cells of algae and fungi hyphae. Algae are usually presented - green (Chlorophyta or blue green (Cyanophyta, a mushroom commonly found is ascomycetae and sometimes basidiomycetae. Mushrooms receive oxygen and carbohydrates from algae, and they in turn provide water, CO2 and mineral salts. Lichens are often found on trees and rocks in unpolluted environments and can be used as a bioindicator species. In during 2015-2016. was realized a survey of epiphytic lichen flora of the western mountains in environment of Vranje. Sampling was carried out at 4 locations: Borino brdo, Krstilovica, Markovo Kale and Pljačkovica.

    Discrimination is an important determinant of health inequalities, and immigrants may be more vulnerable to certain types of discrimination than the native-born. This study analyses the relationship between immigrants' perceived discrimination and various self-reported health indicators. A cross-sectional survey was conducted (2008) amongst a non-random sample of 2434 immigrants from Ecuador, Morocco, Romania and Colombia in four Spanish cities: Barcelona, Huelva, Madrid and Valencia. A factorial analysis of variables revealed three dimensions of perceived discrimination (due to immigrant status, due to physical appearance, and workplace-related). The association of these dimensions with self-rated health, mental health (GHQ-12), change in self-rated health between origin and host country, and other self-reported health outcomes was analysed. Logistic regression was used adjusting for potential confounders (aOR-95%CI). Subjects with worsening self-reported health status potentially attributable to perceived discrimination was estimated (population attributable proportion, PAP %). 73.3% of men and 69.3% of women immigrants reported discrimination due to immigrant status. Moroccans showed the highest prevalence of perceived discrimination. Immigrants reporting discrimination were at significantly higher risk of reporting health problems than those not reporting discrimination. Workplace-related discrimination was associated with poor mental health (aOR 2.97 95%CI 2.45-3.60), and the worsening of self-rated health (aOR 2.20 95%CI 1.73- 2.80). 40% (95% CI 24-53) PAP of those reporting worse self-rated health could be attributable to discrimination due to immigrant status. Discrimination may constitute a risk factor for health in immigrant workers in Spain and could explain some health inequalities among immigrant populations in Spanish society.

  7. Suppression of Listeria monocytogenes by the Native Micro-Flora in Teewurst Sausage

    Full Text Available Modern consumers are interested in the use of non-chemical methods to control pathogens when heat sterilization is not an option. Such is the case with teewurst sausage, a raw spreadable sausage and a popular German commodity. Although Listeria was not found in teewurst, the optimal microbial growing conditions of teewurst coupled with the ubiquity of L. monocytogenes in nature, makes the possibility of contamination of products very possible. This pilot study was conducted to examine teewurst’s native micro-flora’s ability to suppress the outgrowth of L. monocytogenes at 10 °C using standard plate counts and PCR-DGGE. Traditional plating methods showed L. monocytogenes growth significantly decreased when in competition with the teewurst’s native micro-flora (p < 0.05. The native micro-flora of the teewurst suppressed the overall growth of L. monocytogenes by an average of two logs, under these conditions. Denaturing Gradient Gel Electrophoresis (DGGE amplicons with unique banding patterns were extracted from DGGE gel for identification. Brochothrix thermosphacta and Lactobacillus curvatus were identified as a part of the teewurst’s native micro-flora. Although the native micro-flora did not decrease L. monocytogenes to below limits of detection, it was enough of a decrease to warrant further investigation.

    In Tomaszow Mazowiecki, a small town in Poland with the air highly contaminated with gases (SO/sub 2/, CS/sub 2/, H/sub 2/S), a flora of epiphytic and epilithic lichens is present. Lichens are not indicators of air pollution. They are indicators of a complex of microclimatic conditions that enable them to maintain a positive balance of assimilation and of respiratory processes in a given station within the town as well as in natural habitats. 58 references, 16 figures, 7 tables.

    Full Text Available Estudios recientes han demostrado que los afloramientos de yeso de la provincia de Almería (sureste de España son los de mayor valor desde el punto de vista de la conservación de la flora gipsícola ibérica. La necesidad de conservar este patrimonio unida a la imposibilidad real de proteger todos los afloramientos existentes en la región, nos llevó a elucidar qué áreas de la provincia deberían ser consideradas como prioritarias para lograr la conservación de la flora gipsícola de estos enclaves. Para ello, se estableció como objetivo prioritario lograr la representación de todas las especies al menos una vez, a la vez que se plantearon otros escenarios posibles en los que se podría basar la elección de áreas -objetivos complementarios-. Se elaboró la cartografía de los gipsófitos, referida a celdas de 10 km de lado y se evaluó la importancia de cada enclave según diferentes criterios utilizados comúnmente en los estudios sobre selección de áreas (diversidad de especies, rareza de la flora, complementariedad contrastando los resultados obtenidos mediante cada uno de ellos. Los resultados mostraron que la protección de los afloramientos existentes en tan sólo tres cuadrículas (Sorbas, ya protegida principalmente por sus valores geomorfológicos, Venta de los Yesos y Topares sería suficiente para lograr la representación de todos los gipsófitos de la región y alcanzar además varios de los objetivos complementarios de conservación.

    Towards the middle of the XVI century, the empirical physician Martín de la Cruz, in New Spain, compiled a catalogue of the local medicinal herbs and plants, which was translated into Latin by Juan Badiano, professor at the Franciscan college of Tlatelolco. On his side, Dr. Francisco Hernández, the royal physician (protomédico) from 1571 until 1577, performed a systematic study of the flora and fauna in this period. His notes and designs were not published at that time, but two epitomes of Hernández' works appeared, respectively, in 1615 in Mexico and in 1651 in Rome. During the XVIII century, two Spanish scientific expeditions arrived to these lands. They were led, respectively, by the Spanish naturalist Martín Sessé and the Italian seaman, Alessandro Malaspina di Mulazzo, dependent from the Spanish Government. These expeditions collected and carried rich scientific material to Spain. At the end of that century, the Franciscan friar Juan Navarro depicted and described several Mexican medicinal plants in the fifth volume of his botanic work. In the last years of the colonial period, the fundamental works of Humboldt and Bonpland on the geographic distribution of the American plants were published. In the modern age, the first research about the Mexican medicinal botany was performed in the laboratory of the Instituto Médico Nacional [National Medical Institute] under the leadership of Dr. Fernando Altamirano, who started pharmacological studies in this country. Later, trials of cardiovascular pharmacology were performed in the small laboratories of the cardiological unit at the General Hospital of Mexico City, on Dr. Ignacio Chávez' initiative. The Mexican botanical-pharmacological tradition persists alive and vigorous at the Instituto Nacional de Cardiología and other scientific institutions of the country.

  18. Lichen flora of London: effects of air pollution

    Energy Technology Data Exchange (ETDEWEB)

    Laundon, J R

    1967-01-01

    There is good, but not conclusive, evidence that sulfur dioxide is the pollutant which deleteriously affects lichens. The distribution of many lichens in London corresponds closely with the concentrations of sulfur dioxide. Low humidity is also a factor. Apart from actually killing lichens, increasing air pollution can render certain species incapable of colonizing new surfaces, although the old thalli themselves are able to survive as relicts. Until the early nineteenth century air pollution affected the lichen flora only in the small built-up area of London. The halting of building around London since 1938 has brought stability to the lichen vegetation of the area, and since then changes have been minor ones. Recent changes in pollution emissions have had little effect on the lichen flora between 1950 and 1967. This is to be expected as sulfur dioxide concentrations have remained fairly constant at ground level.

    Full Text Available Objectives. We investigated whether abnormal vaginal flora, including bacterial vaginosis (BV, are associated with detection of cervical HIV-1 RNA among HIV-infected women in Mozambique. Methods. We obtained clinical data and vaginal specimens from HIV-infected women registering for their first visit at one of two HIV care clinics in Mozambique. We compared women with detectable cervical HIV viral load (≥40 copies/ml with women with undetectable cervical HIV. Results. We enrolled 106 women. Women with abnormal vaginal flora (intermediate Nugent scores, 4 - 6 were more likely to have detectable cervical HIV RNA then women with normal vaginal flora (adjusted odds ratio 7.2 (95% confidence interval 1.8 - 29.1, adjusted for CD4 count. Women with BV had a non-significantly higher likelihood of detectable cervical HIV than women with normal flora. Conclusions. Abnormal vaginal flora were significantly associated with cervical HIV expression. Further research is needed to confirm this relationship.

    This study aimed to determine the frequency of Chlamydia trachomatis (CT) infection among high risk Brazilian women and evaluate its association with vaginal flora patterns. This was a cross-sectional study, performed in an outpatient clinic of Bauru State Hospital, São Paulo, Brazil. A total of 142 women were included from 2006 to 2008. Inclusion criteria was dyspareunia, pain during bimanual exam, presence of excessive cervical mucus, cervical ectopy or with three or more episodes of abnormal vaginal flora (AVF) in the previous year before enrollment. Endocervical CT testing was performed by PCR. Vaginal swabs were collected for microscopic assessment of the microbial flora pattern. Gram-stained smears were classified in normal, intermediate or bacterial vaginosis (BV), and recognition of Candida sp. morphotypes. Wet mount smears were used for detection of Trichomonas vaginalis and aerobic vaginitis (AV). Thirty-four of 142 women (23.9%) tested positive for CT. AVF was found in 50 (35.2%) cases. The most frequent type of AVF was BV (17.6%). CT was strongly associated with the presence of AV (n = 7, 4.9%, P = 0.018), but not BV (n = 25, 17.6%, P = 0.80) or intermediate flora (n = 18, 12.7%, P = 0.28). A high rate of chlamydial infection was found in this population. Chlamydia infection is associated with aerobic vaginitis.

    In France, human milk banks pasteurize milk for the mother's own hospitalized baby (personalized milk) and for donation. There is specific legislation regulating the activity of human milk banks with bacterial screening of donor milk before and after pasteurization. Milk should be tested for Staphylococcus aureus and total aerobic flora. Any sample of milk positive for aerobic flora and/or S. aureus before and/or after pasteurization should be discarded. The real pathogenicity of the total aerobic flora is actually debated as well as the usefulness of systematic postpasteurization screening. The aim of this study was to quantify milk losses related to prepasteurization contamination by total aerobic flora in a regional milk bank, to identify losses due to contamination with S. aureus or aerobic flora, and to analyze differences between centers. This was a prospective observational study conducted in the regional human milk bank of the Nord-Pas-de-Calais area in France. Data were collected from six major centers providing 80% of the milk collected between June 2011 and June 2012. Variables were the volumes of personalized milk collected by each center, volumes of contaminated milk, and the type of bacteria identified. During the study period, the regional human milk bank treated 4715 L (liters) of personalized milk and 508 L (10.8%) were discarded due to bacteriological screening. Among these 508 L, 43% were discarded because of a prepasteurization contamination with aerobic flora, 55% because of a prepasteurization contamination with S. aureus, and 2% because of other pathogenic bacteria. Postpasteurization tests were positive in 25 samples (0.5%). Only five of these 25 samples were positive before pasteurization and in all cases with S. aureus. A total of 218 L were destroyed because of prepasteurization contamination with total aerobic flora, while the postpasteurization culture was sterile. There was a great difference between centers in the percentage of

    Colorectal cancer is one of the most common human malignant tumors. Recent research has shown that colorectal cancer is a dysbacteriosis-induced disease; however, the role of intestinal bacteria in colorectal cancer is unclear. This review explores the role of intestinal flora in colorectal cancer. In total, 57 articles were included after identification and screening. The pertinent literature on floral metabolites in colorectal cancer from three metabolic perspectives – including carbohydrate, lipid, and amino acid metabolism – was analyzed. An association network regarding the role of intestinal flora from a metabolic perspective was constructed by analyzing the previous literature to provide direction and insight for further research on intestinal flora in colorectal cancer.

  6. Taxonomic research priorities for the conservation of the South African flora

    Full Text Available Taxonomic revisions, monographs and floras are the most important, and often the only source of data for assessing the extinction risk of plants, with recent revisions contributing to more accurate assessments. The recently completed Red List of South African plants involved an overview of the taxonomic literature pertaining to the South African flora, providing an opportunity to identify critical gaps in taxonomic coverage. In this study we identified taxonomic research priorities for effective conservation of South African plants. Priorities were identified at genus level, according to time since last revision, level of endemism, collecting effort, proportion of taxa included in revisions, and specimen identification confidence. Although the results indicate that 62% of the flora has been recently revised, revisionary taxonomic output has declined drastically, particularly in the past 10 years. This decline is a result of a decrease in revisionary productivity per taxonomist and not a result of a decline in the number of working taxonomists. The family Aizoaceae is the top priority for taxonomic research with 55% of taxa in need of revision, followed by Hyacinthaceae with 34% of taxa not yet revised. Ericaceae, Euphorbiaceae, Rutaceae, Malvaceae, Asteraceae and Acanthaceae are also priorities with over 30% of taxa last revised before 1970. We recommend the reinstatement of the Flora of Southern Africa project in an online format in order to centralise South Africa's existing taxonomic information and reinvigorate revisionary taxonomic study. This project will allow South Africa to fulfil its commitments to the Convention on Biodiversity by achieving Target 1 of the Global Strategy for Plant Conservation.

    Full Text Available This study intends to offer a different vision of the concept of prenatal pedagogy, deeply linked to children’s sanitary need. We will try to find out its importance in the university scope through students’ opinions and the analysis of the didactic program of Early Childhood Education Degree.In order to achieve this, we have set ourselves the general objective of gathering information from university students of the Early Education Degree about the importance of training in prenatal education for their future work as teachers, considering that they are the most involved in the education of children in their early stages. Furthermore, we intend to reckon the relevance given to this content by the University of Huelva, one of the educational institutions responsible for teacher training.The data were collected through questionnaires applied to a sample of 58 3rd-4th level students of Early Childhood Education at the University of Huelva. This instrument was selected for the suitability of its application collectively. Moreover, an analysis of the didactic programs of the courses of this degree was carried out to verify the existence of contents of prenatal pedagogy within them.From this research it is derived that certain notions of prenatal pedagogy are essential to become future nursery teachers, thus providing a greater amount of resources when facing our students’ learning process.In conclusion, we checked that the university students surveyed believe that it is necessary to have notions of prenatal pedagogy so as to become efficient teachers. The lack of this notion in the didactic programs represents a formative gap that will have negative repercussions on their initial formation and, consequently, on their educational practice. Therefore, the educational institutions in charge of the preparation of new teachers should consider including prenatal pedagogy within their didactic programs.

    2013-06-27

    Differences in gut commensal flora can dramatically influence autoimmune responses, but the mechanisms behind this are still unclear. We report, in a Th1-cell-driven murine model of autoimmune arthritis, that specific gut commensals, such as segmented filamentous bacteria, have the ability to modulate the activation threshold of self-reactive T cells. In the local microenvironment of gut-associated lymphoid tissues, inflammatory cytokines elicited by the commensal flora dynamically enhanced the antigen responsiveness of T cells that were otherwise tuned down to a systemic self-antigen. Together with subtle differences in early lineage differentiation, this ultimately led to an enhanced recruitment of pathogenic Th1 cells and the development of a more severe form of autoimmune arthritis. These findings define a key role for the gut commensal flora in sustaining ongoing autoimmune responses through the local fine tuning of T-cell-receptor-proximal activation events in autoreactive T cells.

A avaliação da flora emergente demonstrou que, dentre as culturas de cobertura, os tratamentos com milheto e braquiária apresentaram baixa incidência de monocotiledôneas (0,66 pl/m², diferenciando-se, entretanto, apenas do plantio convencional (50,33 pl/m². A ocorrência de dicotiledôneas foi inibida quando em presença de crotalária, trigo sarraceno e milheto (1,00; 1,00; 1,33 pl/m², respectivamente, que se diferenciaram dentre as culturas de cobertura, apenas da aveia (18,66 pl/m². Houve uma elevada população de plantas residuais de milheto (130,66 pl/m², estatisticamente superior ao residual das culturas de braquiária, mucuna cinza, mucuna rajada (1,00; 0,00; 0,33 pl/m², respectivamente. Concluiu-se que a cobertura total do solo foi a proporcionada pela braquiária, com eficiente controle de plantas daninhas. O milheto e a crotalária controlaram muito bem as espécies mono e dicotiledôneas, estabelecendo uma boa cobertura do solo. Contudo, a emergência de plântulas de milheto, após o cultivo desta cultura, pode dificultar o manejo para implantação da cultura subseqüente.

    Full Text Available The flora of the karst plateau Tepoš, which is the part of Vidlič mountain (eastern Serbia was studied. Based on the analysis of the collected material and data from the literature, it was noted that the flora of Tepoš plateau is represented by 486 species, distributed in 284 genera and 68 families of vascular plants. The biological spectra was shown. The hemicriptophytic-terophytic character was established by analyzing the presence of plant life forms. By phytogeographical analysis the presence of 25 area types was established. The euroasian florystic chorion with 258 species of eurasian area type is the most abundant, followed by mediterranean-submediterranean (58 species, central-european (47 species, cosmopolitan (27 species and pontian area type (24 species. In the flora of Tepoš plateau the 9 balkan endemic taxa were recorded, which is 3,14% of total balkan endemic taxa in flora of Serbia. A small number of endemic taxa is expected, considering the low diversity of habitats. Balkan endemic taxa recorded in this area are: Acer hyrcanum subsp. intermedium, Bupleurum flavicans, Crucianella graeca, Eryngium palmatum, Pastinaca hirsuta, Hypericum rumeliacum subsp. rumeliacum, Thymus praecox subsp. jankae, Linaria rubioides subsp. nissana and Viola tricolor subsp. macedonica.

    Zhu Hua

    Full Text Available The floral composition of Yunnan is conspicuously linked to the biogeographical history of this extremely species-rich province in southwestern China. The floristic compositions of three representative regions in Yunnan were compared to reveal their variation with geography. From southern Yunnan, 4150 native species (including subspecies and varieties from 1240 genera and 183 families of seed plants were recognized. From central Yunnan 3389 native species from 1095 genera and 167 families of seed plants were recognized. From northwestern Yunnan 6807 native species from 1296 genera and 166 families of seed plants were recognized. Although these three floras across Yunnan are similar in familial composition, similarities between the floras of southern and northwestern Yunnan are low at the generic and specific levels. The flora of northwestern Yunnan is dominated by families and genera with cosmopolitan and north temperate distributions, while the flora of southern Yunnan is dominated by tropical families and genera. Northwestern Yunnan is composed largely of temperate genera, of which the highest proportion has a north temperate distribution. In contrast, southern Yunnan has mainly tropical genera, of which most have a tropical Asian distribution. The flora of central Yunnan is a combination of southern and northwestern Yunnan. These three floras might be derived from a common Tertiary tropical or subtropical East Asian flora, but the geological history of each region has influenced its flora, and they have remained divergent since the late Tertiary. The flora of northwestern Yunnan has evolved with the uplift of the Himalayas and by gradual proliferation of mainly cosmopolitan and north temperate floristic elements, while the flora of southern Yunnan has evolved with extrusion of the Indochina block and the influence of mainly tropical Asian elements.

In contrast, southern Yunnan has mainly tropical genera, of which most have a tropical Asian distribution. The flora of central Yunnan is a combination of southern and northwestern Yunnan. These three floras might be derived from a common Tertiary tropical or subtropical East Asian flora, but the geological history of each region has influenced its flora, and they have remained divergent since the late Tertiary. The flora of northwestern Yunnan has evolved with the uplift of the Himalayas and by gradual proliferation of mainly cosmopolitan and north temperate floristic elements, while the flora of southern Yunnan has evolved with extrusion of the Indochina block and the influence of mainly tropical Asian elements.

    Full Text Available The present paper is focused on the application of a methodological model specifically designed to develop the tasks related to analysis and dissemination of the Roman Hispania site of Arucci (Aroche, Huelva. The main aim of our approach is to reconcile the diffusion of the results obtained after the excavation, documentation, and the study of the archaeological record with the methodological analysis of a Geographic Information System (GIS. We consider that a GIS is the most appropriate tool in archaeology for this purpose since it allows users to manage a large amount of data in diverse formats and insert it in a closed topographic reference frame. For that purpose, we restrict the field of action to the North House (a house built in the time of Emperor Augustus that lasted until the 3rd century AD. The real power of this research relies on the integration of the digital building archaeological record in a GIS, while the architecture of the Roman house is reconstructed virtually from archaeological remains, in this way the domestic space is visually comprehensible. According to the results obtained in this pilot experience, we can affirm that the union of GIS and infographics allows archaeological reality to surpass the strictly academic scope and promote it to society making possible the Arucci site approachable to professionals of archaeology as well as to the uninitiated. The feasibility of the proposal that was carried out within the North House encourages us to consider the export of this study model to the rest of buildings that make up the site such as the foro, macellum, balneum as, well as other domus.

    This paper describes changes of species composition and population of flora in space and time in western Chitwan, Nepal. This paper also discusses on the changes in flora due to flood and human activities. To illustrate these changes, we used survey data collected from January to April of 1996, 2000, and 2007 from the Barandabhar forest, National Park forest and the forests along the Narayani River banks, grasslands of National Park and common lands of western Chitwan as a part of longitudinal study on "reciprocal relation of population and the environment". From these data, density values were calculated to analyze spatial and temporal changes in flora species composition and population. We also noted the changes of top species in time and space in due course of time. If the species and its rank not changed, their densities (population) values of flora species changed. We found that changes in species composition, population, appearance or disappearance of flora from a particular space (research plot) were noted as a result of natural forces or human activities.

    Full Text Available A stable microbial system in the respiratory tract acts as an important defense mechanism against pathogenic microorganisms. Perturbations in this system may allow pathogens to establish. In an ecological environment such as the respiratory tract, there are many diverse factors that play a role in the establishment of the indigenous flora. In the present work we studied the normal microbial flora of different areas of the respiratory tract of mice and their evolution from the time the mice were born. Our interest was to know which were the dominant groups of microorganisms in each area, which were the first capable of colonizing and which dominated over time to be used as probiotic microorganisms. Our results show that Gram negative facultatively anaerobic bacilli and strict anaerobic microorganisms were the last ones to appear in the bronchia, while aerobic and Gram positive cocci were present in all the areas of the respiratory tract. The number of facultative aerobes and strict anaerobes were similar in the nasal passage, pharynx instilled and trachea, but lower in bronchia. The dominant species were Streptococcus viridans and Staphylococcus saprophyticcus, followed by S. epidermidis, Lactobacilli and S. cohnii I which were present on every studied days but at different proportions. This paper is the first part of a research topic investigating the protective effect of the indigenous flora against pathogens using the mice as an experimental model.

    An over-population of vaginal microorganisms causing inflammatory processes renders it difficult to properly assess the cytopathological exam that aims to screen precedent cervical lesions. On the contrary, the occurrence of the microbial flora saprophyte does not influence correct cythodiagnosis. To assess the composition of vaginal tract aerobic microorganisms of asymptomatic women in menacme and post-menopause, and to analyze the accuracy of cytopathologic, bacterioscopic exams, and culturing of the flora. The women were first submitted to a focused anamnestic interrogatory and then submitted to gynecological exam. A sample of the vaginal fluid was collected with a culture swab and a smear was made on two glass slides for stained bacterioscopic exam (GRAM). The collection of material was then compiled in a cytopathologic smear analysis. All women signed the free and informed consent letter and the project was approved by the Ethics Research Board of Hospital São Paulo - UNIFESP. Bacterioscopy and culture proved to be better than the cytopathologic exam in featuring the bacilli and cocci. The bacterioscopy provided a better detection of the presence of bacilli (p < 0.001); no statistical difference was seen between both exams with respect to the detected cocci. The beta-hemolytic Streptococcus group was of significance in post-menopausal women (p < 0.05). In this study, the bacterioscopic and culture exams of the vaginal fluid were more effective in assessing the vaginal flora and in the detection of bacilli, compared to the cytopathological exam.

    This study is aimed at the analysis of the partitioning of global solar irradiance into its direct and diffuse components at the radiometric station in Badajoz (Spain). The detailed knowledge of the solar radiation field is of increasing interest in Southern Europe due to its use as renewable energy. In particular, the knowledge of the solar radiation partitioning into direct and diffuse radiation has become a major demand for the design and suitable orientation of solar panels in solar power plants. In this study the first measurements of solar diffuse irradiance performed in the radiometric station in Badajoz (Spain) are presented and analyzed in the framework of the partitioning of solar global radiation. Thus, solar global and diffuse irradiance were measured at one-minute basis from 23 November 2009 to 31 March 2010. Solar irradiances were measured by two Kipp&Zonen CMP11 pyranometers, using a Kipp&Zonen CM121 shadow ring for the measurements of solar diffuse irradiance. Diffuse measurements were corrected from the solid angle hidden by the ring and direct irradiance was calculated as the difference between global and diffuse measurements. Irradiance was obtained from the pyranomenters by applying calibration coefficients obtained in an inter-comparison campaign performed at INTA/El Arenosillo, in Huelva (Spain), last September 2009. There, calibration coefficients were calculated using as a reference a CMP11 pyranometer which had been previously calibrated by the Physikalisch-Meteorologisches Observatorium Davos/World Radiation Centre in Switzerland. In order to study the partitioning of the solar radiation, the global and diffuse irradiances have been analyzed for three typical different sky conditions: cloud-free, broken clouds and overcast. Particular days within the period of study have been selected by visual inspection. Along with the analysis of the global and diffuse irradiances themselves, ratios of these irradiances to the downward irradiance at the

    Colorectal cancer is one of the most common types of cancer in the world and its morbidity and mortality rates are increasing due to alterations to human lifestyle and dietary habits. The relationship between human gut flora and colorectal cancer has attracted increasing attention. In the present study, a metabolic fingerprinting technique that combined pyrosequencing with gas chromatography-mass spectrometry was utilized to compare the differences in gut flora profiling and fecal metabolites between healthy individuals and patients with colorectal cancer. The results demonstrated that there were no significant differences in the abundance and diversity of gut flora between healthy individuals and patients with colorectal cancer (P>0.05) and the dominant bacterial phyla present in the gut of both groups included Firmicutes , Bacteroidetes and Verrucomicrobia . At the bacterial strain/genus level, significant differences were observed in the relative abundance of 18 species of bacteria (Pflora profiling and metabolite composition. These findings suggest that gut flora disorder results in the alteration of bacterial metabolism, which may be associated with the pathogenesis of colorectal cancer. The results of the present study are useful as a foundation for further studies to elucidate a potential colorectal cancer diagnostic index and therapeutic targets.

    Blocking transmission of malaria is a reliable way to control and eliminate infection. However, in-depth knowledge of the interaction between Plasmodium and mosquito is needed. Studies suggest that innate immunity is the main mechanism inhibiting development of malaria parasites in the mosquito. Recent studies have found that use of antibiotics that inhibit the mosquito gut flora can reduce the immune response of Anopheles gambiae, thereby contributing to the development of malaria parasites. In our study, we used the non susceptible model of Anopheles dirus-Plasmodium yoelii to explore the effect of Anopheles intestinal flora on the natural resistance of A. dirus to P. yoelii. We found that in mosquitoes infected with Plasmodium, the intestinal flora can regulate expression of thioester-containing protein (TEP1) via an RNAi gene-silencing approach. Our results suggest that in the absence of TEP1, the natural microbiota cannot suppress the development of P. yoelii in A. dirus. This suggests that AdTEP1 plays an important role in the resistance of A. dirus to P. yoelii. The intestinal flora may modulate the development of P. yoelii in A. dirus by regulating TEP1 expression.

  6. Spain's uranium industry

    International Nuclear Information System (INIS)

    Ferguson, M.P.

    1992-01-01

    Spain currently operates nine nuclear reactors totalling over 7,100 MWe of capacity, contributing about one-third of all electricity generated in Spain. Four reactors at advanced stages of construction remain mothballed as the result of a government-imposed moratorium, and a fire at Vandellos 1 in 1989 led to its premature closure and to a revival of anti-nuclear sentiment in the country. In the new national energy plan, which was sent to the Spanish Parliament on July 25, 1991, Spain opted to continue the nuclear moratorium that began in 1984 and rely upon conservation measures, additional natural gas imports, and electricity imports to meet expected demand. Under the new plan, nuclear power's share of Spain's total installed electrical generating capacity will fall from about 17 percent in 1990, to approximately 14 percent by the end of the century, as only the current nuclear facilities will continue to operate and no new nuclear plants will be built. Spain's integration into the European Community also is affecting the country's energy plans, prompting consolidation within the Spanish electricity sector in order to be more competitive in Europe. To supply the existing reactors, the government is supporting a major expansion of the country's domestic uranium industry

    Full Text Available OBJECTIVE: To determine the conjunctival bacterial flora present in patients with Stevens-Johnson syndrome. METHODS: A prospective study of the conjunctival bacterial flora was performed in 41 eyes of 22 patients with Stevens-Johnson syndrome. The information gathered included the patient's sex and age, the duration of disease, the cause of Stevens-Johnson syndrome, and treatments. Scrapings of the inferior conjunctival fornix were performed in both eyes. Fourteen days before scraping, the patients were asked to interrupt all topical medication and start using 0.5% nonpreserved methylcellulose. The microbiological evaluation included microorganism identification and determination of antibiotic sensitivity. RESULTS: Of 22 patients (41 eyes, 14 (64% were females, and eight (36% were males. The mean age was 33.2 years, and the mean duration of disease was 15.6 years. Visual acuity ranged from light perception to 20/25 (1.57 logMar. The treatment received by most patients consisted of tear substitutes, topical antibiotics, and contact lenses. Bacterial identification was positive in 39 eyes (95% and negative in two eyes (5%. Gram-positive cocci accounted for 55.5% of the microorganisms, whereas gram-positive bacilli and gram-negative bacilli accounted for 19% and 25.5%, respectively. Half of the patients (54% had multiple bacterial species in their flora, and only one bacterial species was identified in the other half. Resistant bacteria were isolated from four eyes. The antibiotic sensitivity results for the Streptococcus group showed the lowest sensitivity and the highest microbial resistance identified. CONCLUSION: Patients with Stevens-Johnson syndrome have a diverse conjunctival flora that includes many pathogenic species.

    Pregnancy and diabetes are regarded as individual risk factors for vaginal candidiasis. The high prevalence of vaginal candidiasis in pregnant diabetic women can be explained by disruption of the balance of the vaginal normal flora. However, little is known about the overall structure and composition of the vaginal fungal flora in pregnant diabetic women. In the present study, the diversity and richness of the vaginal fungal flora in healthy non-pregnant women (group HN), healthy pregnant women (group HP), women with gestational diabetes mellitus (group GDM), and pregnant women with diabetes mellitus type I (group T1DM) were investigated using an 18S rRNA gene clone library method. Our data demonstrated that the composition of the vaginal fungal flora in the four groups could be divided into two phyla (Ascomycetes, 20/26, and Basidiomycetes, 6/26). The most predominant vaginal fungal species belonged to the Candida and Saccharomyces genera, uncultured fungi, and a large number of low-abundance taxa that were unrecorded or underrepresented in previous studies using cultivation-dependent methods. Variation in operational taxonomic units (OTUs) between the study cohorts was generally high in the clone libraries, as 9, 13, 17, and 20 phylotypes were identified in groups HN, HP, GDM, and T1DM, respectively. The Shannon indices of groups GDM and T1DM (with poorer glycemic control) were significantly higher compared to groups HN and HP (p flora in pregnant diabetic women and demonstrated that poor glycemic control might be associated with disturbances in the vaginal fungal flora.

    Full Text Available Abstract Background Discrimination is an important determinant of health inequalities, and immigrants may be more vulnerable to certain types of discrimination than the native-born. This study analyses the relationship between immigrants' perceived discrimination and various self-reported health indicators. Methods A cross-sectional survey was conducted (2008 amongst a non-random sample of 2434 immigrants from Ecuador, Morocco, Romania and Colombia in four Spanish cities: Barcelona, Huelva, Madrid and Valencia. A factorial analysis of variables revealed three dimensions of perceived discrimination (due to immigrant status, due to physical appearance, and workplace-related. The association of these dimensions with self-rated health, mental health (GHQ-12, change in self-rated health between origin and host country, and other self-reported health outcomes was analysed. Logistic regression was used adjusting for potential confounders (aOR-95%CI. Subjects with worsening self-reported health status potentially attributable to perceived discrimination was estimated (population attributable proportion, PAP %. Results 73.3% of men and 69.3% of women immigrants reported discrimination due to immigrant status. Moroccans showed the highest prevalence of perceived discrimination. Immigrants reporting discrimination were at significantly higher risk of reporting health problems than those not reporting discrimination. Workplace-related discrimination was associated with poor mental health (aOR 2.97 95%CI 2.45-3.60, and the worsening of self-rated health (aOR 2.20 95%CI 1.73- 2.80. 40% (95% CI 24-53 PAP of those reporting worse self-rated health could be attributable to discrimination due to immigrant status. Conclusions Discrimination may constitute a risk factor for health in immigrant workers in Spain and could explain some health inequalities among immigrant populations in Spanish society.

    Highlights: • Variability of radon exhalation rates from PG piles has been studied using numerical simulation supported by experimental data. • Most relevant parameters controlling the exhalation rate are radon potential and moisture saturation. • Piling up the waste increasing the height instead of the surface allows the reduction of the exhalation rate. • A proposed cover here is expected to allow exhalation rates reductions up to 95%. - Abstract: Nearly 1.0 × 10{sup 8} tonnes of phosphogypsum were accumulated during last 50 years on a 1200 ha disposal site near Huelva town (SW of Spain). Previous measurements of exhalation rates offered very variable values, in such a way that a worst case scenario could not be established. Here, new experimental data coupled to numerical simulations show that increasing the moisture contents or the temperature reduces the exhalation rate whilst increasing the radon potential or porosity has the contrary effect. Once the relative effects are compared, it can be drawn that the most relevant parameters controlling the exhalation rate are radon potential (product of emanation factor by {sup 226}Ra concentration) and moisture saturation of PG. From wastes management point of view, it can be concluded that piling up the waste increasing the height instead of the surface allows the reduction of the exhalation rate. Furthermore, a proposed cover here is expected to allow exhalation rates reductions up to 95%. We established that the worst case scenario corresponds to a situation of extremely dry winter. Under these conditions, the radon exhalation rate (0.508 Bq m{sup −2} s{sup −1}) would be below though close to the upper limit established by U.S.E.P.A. for inactive phopsphogypsum piles (0.722 Bq m{sup −2} s{sup −1})

Los muestreos fueron realizados en las épocas de secas y lluvias (abril, 2008 y junio, 2008, respectivamente. La atribución de flora presente para 5 formas de vida (pastos marinos + epífitas, calcificadas/costrosas, filamentosas, tubulares/ laminares, racemosas/carnosas fue realizada con base en el análisis de la cobertura vegetal muestreada en 50 m2. Al comparar las especies del presente estudio con las especies reportadas en la literatura previamente se observó que de las 58 especies, 25 son nuevos reportes para Arrecife Hornos. La flora en 2008 fue pobre en comparación con las reportadas en 1962 (27 especies comparadas con las 58 especies. La flora de 1962 tenía un índice de Cheney de 3.5 que indica una flora mixta con elementos tropicales y subtropicales, sin embargo, para el presente estudio observamos un índice de 25 lo cual indica una flora tropical sin elementos subtropicales. Diversas especies de Sargassum hystrix var. buxifolium y S. polyceratium, comunes en 1962 han desparecido de Arrecife Hornos y especies con afinidad a aguas tropicales como Caulerpa racemosa y C. sertularioides están ahora presentes. Los valores de cobertura nos demuestran que Arrecife Hornos está cubierto en su mayoría por Thalassia testudinum y algas calcificadas (Lithophyllum aff. congestum y en menor proporción algas filamentosas, laminares y racemosas. El presente estudio sugiere la existencia de cambios en la composición y cobertura fitobentónica de Arrecife Hornos.

  16. Living on the edge: timing of Rand Flora disjunctions congruent with ongoing aridification in Africa.

    The Rand Flora is a well-known floristic pattern in which unrelated plant lineages show similar disjunct distributions in the continental margins of Africa and adjacent islands-Macaronesia-northwest Africa, Horn of Africa-Southern Arabia, Eastern Africa, and Southern Africa. These lineages are now separated by environmental barriers such as the arid regions of the Sahara and Kalahari Deserts or the tropical lowlands of Central Africa. Alternative explanations for the Rand Flora pattern range from vicariance and climate-driven extinction of a widespread pan-African flora to independent dispersal events and speciation in situ. To provide a temporal framework for this pattern, we used published data from nuclear and chloroplast DNA to estimate the age of disjunction of 17 lineages that span 12 families and nine orders of angiosperms. We further used these estimates to infer diversification rates for Rand Flora disjunct clades in relation to their higher-level encompassing lineages. Our results indicate that most disjunctions fall within the Miocene and Pliocene periods, coinciding with the onset of a major aridification trend, still ongoing, in Africa. Age of disjunctions seemed to be related to the climatic affinities of each Rand Flora lineage, with sub-humid taxa dated earlier (e.g., Sideroxylon) and those with more xeric affinities (e.g., Campylanthus) diverging later. We did not find support for significant decreases in diversification rates in most groups, with the exception of older subtropical lineages (e.g., Sideroxylon, Hypericum, or Canarina), but some lineages (e.g., Cicer, Campylanthus) showed a long temporal gap between stem and crown ages, suggestive of extinction. In all, the Rand Flora pattern seems to fit the definition of biogeographic pseudocongruence, with the pattern arising at different times in response to the increasing aridity of the African continent, with interspersed periods of humidity allowing range expansions.

    Silvia Barazorda Romero

    2015-01-01

    Full Text Available The aims of this study were to characterize the choanal and cloacal aerobic bacterial flora in healthy captive green iguanas and to compare it with the bacterial flora of the biofilm present in the water container of each terrarium. Samples were collected from the choana and the cloaca of 20 healthy captive adult green iguanas and from the biofilm of 15 water containers. The final identification of aerobic bacteria was performed by matrix-assisted laser desorption ionization time-of-flight mass spectrometry. Salmonella positive samples were serotyped. The most common strains observed at each test location were from 1 choanae: Staphylococcus spp., Enterobacter cloacae and Comamonas testosteroni; 2 cloacae: Citrobacter spp., Salmonella spp. and Corynebacterium spp.; and 3 biofilms: Pseudomonas spp., Salmonella spp. and Acidovorax spp. We showed that apart from Salmonella spp., the choanal and cloacal bacterial flora differed from the microorganisms present in the biofilm of the animal’s water container. These data revealed that healthy captive adult green iguanas harbored several aerobic bacterial strains that in immunosuppressed reptiles may act as opportunistic pathogens. Also, several of the aerobic bacteria identified in samples are potential zoonotic agents. Characterization of the normal background flora in captive reptiles and their environment can contribute to an understanding of the spread of bacterial contamination and the risk of potential zoonotic diseases for people in contact with these animals.

    Sampling expeditions to Churchill in the Canadian subarctic were completed with the aim of compiling a molecular-assisted survey of the macroalgal flora (seaweeds) for comparison to published accounts for this area, which are based on morphological identifications. Further, because the Churchill region was covered by ice until recently (~10,000 before present), the current algal flora has had to migrate from adjacent waters into that region. We used our DNA barcode data to predict the relative contribution of the North Atlantic and North Pacific floras (Likely Source Region) in repopulating the Churchill region following the most recent glacial retreat. We processed 422 collections representing ~50 morpho-species, which is the approximate number reported for this region, and generated DNA barcode data for 346 of these. In contrast to the morpho-species count, we recovered 57 genetic groups indicating overlooked species (this despite failing to generate barcode data for six of the ~50 morpho-species). However, we additionally uncovered numerous inconsistencies between the species that are currently listed in the Churchill flora (again as a result of overlooked species diversity, but combined with taxonomic confusion) and those identified following our molecular analyses including eight new records and another 17 genetic complexes in need of further study. Based on a comparison of DNA barcode data from the Churchill flora to collections from the contiguous Atlantic and Pacific floras we estimate that minimally 21% (possibly as much as 44%) of the Churchill flora was established by migration from the Pacific region with the balance of species arriving from the Atlantic (predominantly North American populations) following the last glacial retreat. Owing to difficulties associated with the morphological identification of macroalgae, our results indicate that current comprehension of the Canadian Arctic flora is weak. We consider that morphology-based field

    Intestinal flora performs a crucial role in human health and its imbalance may cause numerous pathological changes. The liver can also affect the intestinal function through bile secretion via the enterohepatic cycle. The pathophysiological association between the gut and the liver is described as the gut-liver axis. The present study investigated the role of intestinal flora in alcohol-induced liver fibrosis. A total of 36 C57 mice were randomly and equally divided into 3 different dietary regimes: Group I (alcohol injury; received alcohol); group II (alcohol injury with flora imbalance; received alcohol plus lincomycin hydrochloride) and group III (alcohol injury with corrected flora imbalance; received alcohol, lincomycin hydrochloride and extra probiotics). The present study then investigated several indicators of liver damage. Alkaline phosphatase (ALP) levels, aspartate aminotransferase (AST) levels and alanine aminotransferase (ALT) levels in mice serum were studied. Masson staining and Annexin V-fluorescein isothiocyanate/propidium iodide double staining was also performed, and the expression of mothers against decapentaplegic homolog (smad) 3 and smad4 proteins in hepatic stellate cells (HSCs) of the mice was examined using western blot analysis. The levels of serum ALP, AST and ALT were the highest in group II mice, and all 3 levels decreased in group III mice compared with those from group II. The degree of liver fibrosis was aggravated in group II mice compared with group I mice. The apoptosis of HSCs was significantly inhibited in group II mice, but was increased in group III mice. The HSCs in group II mice exhibited higher expression of smad3 and smad4, whilst group III mice (with corrected intestinal flora imbalance) exhibited downregulated expression of smad3 and smad4. The present data indicates that the intestinal flora perform a significant role in maintaining liver homeostasis. Furthermore, an imbalance of intestinal flora can exacerbate alcohol

    The role of maternal vaginal bacteria on the colonization of neonatal gut is still a matter of discussion. Our aim was to estimate the role of maternal vaginal flora on the development of intestinal flora in neonates and 3-month-old infants. Seventy-nine maternal-neonatal pairs were included in the study. Vaginal swabs were taken before the rupture of membranes after admission to the delivery ward. First neonatal stool (meconium) and stool at 3-month-old infants were collected and cultured. All samples were subjected to microbiological analysis for Streptococcus, Staphylococcus, Bifidobacterium, Clostridium (including C. difficile), Lactobacillus, Escherichia coli, Klebsiella pneumoniae, and Candida. Maternal vagina was colonized mainly by streptococci (67%) followed by lactobacilli (58%) and Candida spp. (39%). Vaginal streptococci influenced the intestinal colonization in infants with staphylococci, C. difficile, and candida. Vaginal lactobacilli influenced colonization with C. difficile, and Candida. Vaginal flora is a potent factor influencing the development of bacterial flora in the neonatal and infantile gut. The extension of the observation period until 3 months of life allow to discover the potential changes in the intestinal flora of children.

    In this study, we investigated the effect of administration of 5 strains of lactic acid bacteria (LAB) isolated from traditional Chinese sourdough on the flora balance of gastrointestinal tract of mice. We specifically measured Enterococcus, Enterobacter, Bacteroides, and Lactobacillus by plate count and real-time PCR methods, and α-glucosidase, lactate dehydrogenase, esterase, and aminopeptidase activities as indicative of metabolism of sugar, fat, and protein from LAB isolated from feces of mice in vitro. The results showed that administration of Lactobacillus acidophilus LAC0201 and Lactobacillus fermentum LFE0302 lowered the uricacid index of serum. Lactobacillus acidophilus LAC0201, L. fermentum LFE0302, as well as Lactobacillus curvatus LCU0401 administration resulted in a reduction in the opportunistic pathogens (i.e., Enterococcus and Enterobacter), meanwhile, administration of L. fermentum LFE0302 and Lactobacillus sp. ULA0104 resulted in an increase in the counts of Lactobacillus. Lactobacillus fermentum LFE0302 administration increased starch digestion of intestinal flora after 4wk of feeding and also resulted in increased α-glucosidase activity in the intestinal flora after 3wk of feeding. We found a similar trend in esterase activity after administration of L. acidophilus LAC0201 for 3wk. Hence, our study suggested that LAB from Chinese sourdough might be used as potential probiotics to strengthen the flora balance in gastrointestinal tract and positively change the metabolism of nutrients through bacterial enzyme activities.

    Deliberate or accidental initiation of explosives can produce a range of potentially damaging fire and explosion effects. Quantification of the consequences of such effects upon the surroundings, particularly on people and structures, has always been of paramount importance. Information on the effects on flora and fauna, however, is limited, with probably the weakest area lying with fragmentation of buildings and their effects on different small mammals. Information has been used here to gain an appreciation of the likely magnitude of the potential fire and explosion effects on flora and fauna. This is based on a number of broad assumptions and a variety of data sources including World War II bomb damage, experiments performed with animals 30-40 years ago, and more recent field trials on building break-up under explosive loading.

    The Emergency Cardiac Care Committee of the American Heart Association has recently recommended utilizing protective barrier precautions during CPR (1,2). We assessed 17 mask and faceshield resuscitation devices for adequacy of barrier protection. Eight of the devices were faceshields (CPR Microshield, Hygenic, MedCare Mask, Resusci, Samaritan, Sealeasy, Portex); 8 were mask devices (Laerdal, Dyna Med, MTM Emergency Lung Ventilator, MTM Emergency Resuscitator, Res-Q-Flo, Rightway Mouth-to-Mask Resuscitation, Trufit), and one of the devices did not meet the criteria for either faceshield or mask (Lifesaver). All masks were disinfected, applied to the investigator's face as directed by the manufacturers' instructions, and then cultured for oral aerobic bacterial flora on the rescuer side. No mask devices cultured positive for oral aerobic bacterial flora, while 6 of 8 faceshield devices cultured positive for oral aerobic bacterial flora (P less than 0.007). The CPR Microshield and the Portex faceshield were the only devices that did not develop a positive culture. We conclude that all ventilation devices with a one-way valve, except the Sealeasy device, provide adequate barrier type protection from oral aerobic bacterial flora when simulating mouth-to-barrier type protection when performing mouth-to-mouth ventilation.

    This report highlights the level of plant diversity that prevails in IGCAR and PFBR sites. The stress tolerant sandy-shore flora of natural vegetation adorns the Campus. It is bewitchingly blended with horticultural design and sets the backdrop of the nuclear industries- MAPS I and II and the incumbent PFBR. The floristic analysis points out the genetic richness of the campus (over 650 plant species in a narrow strip of ∼2500 acres), which can also serve as genetic reserve for coastal flora. Based on the study, a digitized inventory of plant resources of Kalpakkam is now made available. Taxonomy, distribution, vernacular name, uses, produces, bio-chemical component, ethnobotany, photograph are featured in the database. The survey highlights the potential of mangroves as bio-fence protecting against cyclone and sand and salt laden wind erosion. Such information may also be useful to understand the flora of east coast, in general. Biodiversity information gains importance for its use in caring the ecosystem and for its wise management at every micro-level down to the back yard of individual institution, which is the need of the hour. The sustainable use and preserving the biological resources maximize the net long-term benefits to mankind. (author)

    Full Text Available Com o objetivo estudar a relação existente entre o banco de sementes e o posterior estabelecimento da flora emergente de plantas daninhas, sob sistema de semeadura direta e convencional, realizou-se uma pesquisa no município de Pedra Preta-MT. O banco de sementes e a flora emergente foram avaliados, em cada sistema de cultivo, em 50 células contíguas de 1 m². O banco de sementes foi determinado a partir de amostras de 2,4% da área de cada célula na profundidade de 0-5 cm, em setembro de 2003, por meio da técnica de flotação. A flora emergente foi avaliada por meio de seis levantamentos sucessivos, até novembro de 2004, realizados na área total de cada célula, com retirada dos indivíduos após cada avaliação. Esses dados foram utilizados para calcular os parâmetros fitossociológicos e também a correlação entre o banco de sementes e a flora emergente. A similaridade entre o banco de sementes e a flora emergente foi baixa tanto no sistema de semeadura direta quanto no convencional. Houve correlação significativa apenas para Amaranthus deflexus e Eleusine indica entre o banco de sementes e a flora emergente.

    Bacteria of normal intestinal flora are frequent carriers of markers of antimicrobial drug resistance. Resistance genes may be exchanged with other bacteria of normal flora as well as with pathogenic bacteria. The increase in the number of markers of resistance is one of the major global health problems, which induces the emergence of multi-resistant strains. The aim of this study is to confirm the presence of markers of resistance in bacteria of normal facultative anaerobic intestinal flora in our region. The experiment included a hundred fecal specimens obtained from a hundred healthy donors. A hundred bacterial strains were isolated (the most numerous representatives of the normal facultative-anaerobic intestinal flora) by standard bacteriological methods. The bacteria were cultivated on Endo agar and SS agar for 24 hours at 37 degrees C. Having been incubated, the selected characteristic colonies were submitted to the biochemical analysis. The susceptibility to antimicrobial drugs was tested by standard disc diffusion method, and the results were interpreted according to the Standard of Clinical and Laboratory Standards Institute 2010. The marker of resistance were found in 42% of the isolated bacteria. The resistance was the most common to ampicillin (42% of isolates), amoxicillin with clavulanic acid (14% of isolates), cephalexin (14%) and cotrimoxazole (8%). The finding of 12 multiresistant strains (12% of isolates) and resistance to ciprofloxacin were significant. The frequency of resistance markers was statistically higher in Klebsiella pneumoniae compared to Escherichia coli of normal flora. The finding of a large number of markers of antimicrobial drug resistance among bacteria of normal intestinal flora shows that it is necessary to begin with systematic monitoring of their antimicrobial resistance because it is an indicator of resistance in the population.

    2016-11-14

    Background The systematic analysis of a large number of comparable plant trait data can support investigations into phylogenetics and ecological adaptation, with broad applications in evolutionary biology, agriculture, conservation, and the functioning of ecosystems. Floras, i.e., books collecting the information on all known plant species found within a region, are a potentially rich source of such plant trait data. Floras describe plant traits with a focus on morphology and other traits relevant for species identification in addition to other characteristics of plant species, such as ecological affinities, distribution, economic value, health applications, traditional uses, and so on. However, a key limitation in systematically analyzing information in Floras is the lack of a standardized vocabulary for the described traits as well as the difficulties in extracting structured information from free text. Results We have developed the Flora Phenotype Ontology (FLOPO), an ontology for describing traits of plant species found in Floras. We used the Plant Ontology (PO) and the Phenotype And Trait Ontology (PATO) to extract entity-quality relationships from digitized taxon descriptions in Floras, and used a formal ontological approach based on phenotype description patterns and automated reasoning to generate the FLOPO. The resulting ontology consists of 25,407 classes and is based on the PO and PATO. The classified ontology closely follows the structure of Plant Ontology in that the primary axis of classification is the observed plant anatomical structure, and more specific traits are then classified based on parthood and subclass relations between anatomical structures as well as subclass relations between phenotypic qualities. Conclusions The FLOPO is primarily intended as a framework based on which plant traits can be integrated computationally across all species and higher taxa of flowering plants. Importantly, it is not intended to replace established

    Full Text Available Composition of weed flora is highly dynamic and depends upon great number of factors, of which cultural practices that are applied by humans in certain crops are the most important. One of the most frequently grown plants in the world and in our country is potato (Solanum tuberosum L., Solanaceae, due to its high biological and nutritive value. Therefore, in the paper was presented taxonomic analysis of weed flora in potato grown conventionally and according to the principles of organic agricultural production, with the intention to point out to eventual differences between present weeds. Of the total number of identified species, from phylum Equisetophyta and class Equisetopsida, in organic potato crop, was determined only one, Equisetum arvense. Of remaining 38 weeds from phylum Magnoliophyta., classified into two classes, Magnoliopsida and Liliopsida. On both of potato growing systems, 39 weed species were found, classified into 16 families and 32 genus. Of the total number, 31 species was identified in conventional potato crop, and only 23 species in potato crop grown according to organic principles, which is for about quarter less. Biological spectrum of weed flora in both potato growing systems is pronouncedly of terrophytic – geophytic type. In the spectrum of area types were recorded differences, i.e. in the conventional potato crop represented are only widely distributed species, while in the organic crop, beside species of wide distribution are also present elements of Pontic group.

  9. Spain.

    Spain is a constitutional monarchy with a population of 38.3 million growing at .5%/year. The most striking topographical features are the high plateaus and internal compartmentalization by mountain and river barriers. Nearly 3/4 of the country is arid. The Iberian peninsula was the scene of successive invasions and warfare for centuries. Phoenicians, Greeks, Carthaginians, Moors, Celts, Romans, and Visigoths all invaded at some time. The present language, religion, and laws stem from the Roman Period. The Reconquest from the North African Moors lasted over 700 years until they were driven out in 1492. The unification of present day Spain was complete by 1512. A period of dictatorial rule from 1923-31 ended with establishment of the Second Republic which saw increasing political polarization culminating in the Spanish Civil War. Franco's victory in 1939 was followed by official neutrality but pro-Axis policies during World War II. Spain's economy began to recover during the 1950s, but large scale modernization and development did not occur until the 1960s. Prince Juan Carlos de Borbon y Borbon, Franco's personally designated heir, assumed the title of king and chief of state with Franco's death in 1975. Franco's last prime minister was replaced in July 1976 in order to speed the pace of post-Franco liberalization. Spain's 1st parliamentary elections since 1936 were held in 1977, and a new constitution protecting human and civil rights and granting due process was overwhelmingly approved in 1978. The constitution also authorized creation of regional autonomous governments. By the mid-1970s, Spain had developed a strong and diversified industrial sector and a thriving tourist industry. From 1975-83, there were 8 years of double-digit inflation, an average growth rate of 1.5% in real terms, and an increase in unemployment from about 4.7% to 18.4%. By 1984 there was substantial improvement in inflation and the balance of payments. Goals of current government economic

    Full Text Available The genus Silene (family Caryophyllaceae comprises more than 700 species and it is one of the larger genera of the World’s flora. Studying the flora of the plain part of Kosovo and Metohija, in the village of Gračanica, on the eastern rim of the Kosovo basin (approximately 10 km to the south of Priština, near the Gračanka stream, we identified a weed and ruderal species, Silene noctiflora. The part of the stream bank is urbanised and turned into a quay. The quay is regularly maintained implying that the banks are regularly weeded and the riverbeds are cleaned as the Typha latifolia species rapidly grows; it may be the reason why this species was not immediately detected and appropriately identified. Except for the afore mentioned locality, the species was also reported on the neglected arable fields and tilths, around the unkempt orchards, along the new tarmac road between Gračanica and Laplje Selo, on the locality called Labura. Silene noctiflora is not mentioned for the region of Kosovo and Metohija in the new and revised edition of the book Flora of Serbia 2.

    In order to investigate the influence of aflatoxin B1 (AFB1) on intestinal bacterial flora, 24 Kunming mice (KM mice) were randomly placed into four groups, which were labeled as control, low-dose, medium-dose, and high-dose groups. They were fed intragastrically with 0.4 mL of 0 mg/L, 2.5 mg/L, 4 mg/L, or 10 mg/L of AFB1 solutions, twice a day for 2 months. The hypervariable region V3 + V4 on 16S rDNA of intestinal bacterial flora was sequenced by the use of a high-flux sequencing system on a Miseq Illumina platform; then, the obtained sequences were analyzed. The results showed that, when compared with the control group, both genera and phyla of intestinal bacteria in the three treatment groups decreased. About one third of the total genera and one half of the total phyla remained in the high-dose group. The dominant flora were Lactobacillus and Bacteroides in all groups. There were significant differences in the relative abundance of intestinal bacterial flora among groups. Most bacteria decreased as a whole from the control to the high-dose groups, but several beneficial and pathogenic bacterial species increased significantly with increasing dose of AFB1. Thus, the conclusion was that intragastric feeding with 2.5~10 mg/mL AFB1 for 2 months could decrease the majority of intestinal bacterial flora and induce the proliferation of some intestinal bacteria flora.

    The potential role of a patient's resident microbial flora in the risk of acquiring multiresistant bacteria (MRB) during hospitalization is unclear. We investigated this role by cross-sectional study of 103 patients at risk of acquisition of Staphylococcus aureus (SA), resistant (MRSA) or not (MSSA) to methicillin, recruited in four French hospitals. The flora was analysed by an exhaustive culture-based approach combined with molecular and/or mass-spectrometry-based identification, and SA strain typing. Forty-three of the 53 SA-negative patients at entry were followed for up to 52 weeks: 19 (44.2%) remained negative for SA and 24 (55.8%) became positive, including 19 (79%) who acquired an MSSA, four (17%) who acquired an MRSA and one who acquired both (4%). Fifty-one different species were identified among the 103 patients, of which two, Corynebacterium accolens and Staphylococcus haemolyticus (p = 0.02-0.01), were more prevalent in the absence of SA. However, the same number of patients carrying or not these two species acquired an MSSA/MRSA during follow-up, regardless of antibiotic treatment received. Clustering analysis showed that the microbial flora was highly specific to each patient, and not predictive for acquisition of MSSA/MRSA or not. Patient-specific microbial resident flora is not predictive of SA acquisition. © 2013 The Authors Clinical Microbiology and Infection © 2013 European Society of Clinical Microbiology and Infectious Diseases.

    Mice exposed to 10 Gy cobalt-60 radiation were given intramuscular antimicrobial therapy of gentamicin, metronidazole, or a combination. Mortality in mice treated with metronidazole alone or in combination with gentamicin occurred earlier than in controls (P < 0.001). Microorganisms were recovered from blood, spleen, and liver of the metronidazole-treated mice earlier than from other groups. Predominant organisms recovered from these animals were Enterobacteriaceae. Quantitative cultures of ileal flora showed decrease in aerobic, facultative anaerobic and strict anaerobic bacteria after irradiation, and a subsequent increase only in the number of strict aerobic bacteria. Compared to untreated mice, a rapid decrease (by 8.8 logs) in anaerobic flora occurred in mice treated with metronidazole 5 days after irradiation, followed by a rapid increase in the number of aerobic organisms which coincided with the earlier mortality in this group. Data suggest that antimicrobial agents decreasing the number of the strict anaerobic component of the gut flora enhance systemic infection by aerobic or facultative anaerobic bacteria, facilitating post-irradiation mortality.

    This study was carried out in order to isolate and identify the normal conjunctival fungal flora from Caspian miniature, Thoroughbred, Turkmen and Persian Arab breeds in Tehran, Iran. A total of seventy-two adult healthy horses were studied. Ocular samples were collected from right and left eyes by using sterile cotton swabs; samples were cultured on Sabouraud dextrose agar and incubated at 30°C for 7-10 days. Molds and yeasts were identified using macro and micro-morphological and physiological characteristics. Number of fungal colonies per eye varied between 0 and 123 colony forming units (CFUs). The most predominant fungal isolates were Aspergillus (19.9%), Rhizopus (15.9%) and Penicillium (15.1%). No significant differences were observed between types of eye fungal floras in different breeds. Caspian miniature horses had significantly the highest number of fungal isolates in compare with other breeds (P<0.001), however no significant difference was observed among other breeds under study. The fungal isolates were almost the same as with studies performed in other countries, although differences in species isolated could be related to geographic and climate difference.

    The silkworm Bombyx mori is a poikilotherm and is therefore sensitive to various climatic conditions. The influence of temperature on the intestinal flora and the relationship between the intestinal flora and gene expression in the silkworm remain unknown. In the present study, changes of the intestinal flora at 48, 96 and 144 h following transient high temperature treatment (THTT) of 37 °C for 8 h were investigated. According to principal component analysis, the abundances of Enterococcus and Staphylococcus showed a negative correlation with other dominant genera. After THTT, the gene expression levels of spatzle-1 and dicer-2 were increased and decreased, respectively, which suggested that the Toll and RNAi pathways were activated and suppressed, respectively. The species-gene expression matrix confirmed that the spatzle-1 and dicer-2 gene expression levels were negatively and positively correlated, respectively, with the abundance of Enterococcus and Staphylococcus in the control. The abundance of Variovorax post-THTT was positively correlated with the spatzle-1 gene expression level, whereas the community richness of Enterococcus was negatively correlated with the spatzle-1 gene expression level and positively correlated with the dicer-2. The results of the present investigation provide new evidence for understanding the relationships among THTT, intestinal flora and host gene expression.

    The vaginal flora from postmenopausal women with pelvic organ prolapse (POP) is different from younger women. We hypothesized that the decision of a surgical route using a mesh would modify the vaginal flora. The purpose of this study was to analyze the vaginal flora from postmenopausal women that were submitted to abdominal sacrocervicopexy or vaginal sacrospinous fixation. A pilot, randomized controlled study with 50 women aged 55 to 75 years (n = 25; abdominal sacrocervicopexy + subtotal hysterectomy; n = 25 vaginal sacrospinous fixation + vaginal hysterectomy) was performed. A polyvinylidene mesh was used in both arms. The vaginal content analysis was collected before and 60 days after the surgery. The type of flora, the presence of lactobacilli/leukocytes, and the Nugent criteria were analyzed. Most of the women were white (80%), with at least 1 comorbidity (69.9%), did not present sexual activity (60%), and presented advanced stage 4 POP. Two thirds of women presented a type 3 flora, and half of them did not present lactobacilli (48.3%). About the Nugent criteria, 51.7% presented normal flora, 46.6% found altered flora, and 1.7% had bacterial vaginosis. There were no differences about the type of flora (P = 1), number of lactobacilli (P = 0.9187), Nugent criteria (P = 0.4235), inflammation (P = 0.1018), and bacterial vaginosis (P = 0.64) before and after surgery in both groups. In this pilot study, the use of synthetic mesh by vaginal or abdominal route did not affect the vaginal flora in postmenopausal women operated on by POP surgery.

    The irradiation of the food with gamma rays is an effective protection method. Microbial contaminations are decreased, spoilage is deleted and shelf life of the product is increased by this method. In the study, effect of gamma irradiation on microflora of the minced turkey meat is explored. The first group is determined as control group and the irradiation wasn't applied to this group. The other groups were irradiated 1.0, 2.0 and 3.0 kGy dosages respectively. According to our study we observed that microbial flora is decreased as a result of irradiation procedure. The level of decrease of the microbial flora depended on the dosage of irradiation. We thing low dosage of irradiation applications can be used successfully to the minced turkey meat if it is combined with hygienic manufacturing techniques

    Acid suppression therapy in critically ill patients significantly reduces the incidence of stress ulceration and gastrointestinal (GI) bleeding; however, recent studies suggest that proton pump inhibitors (PPIs) increase the risk of pneumonia. We wanted to test the hypothesis that acid suppressive therapy promotes alteration in the bacterial flora in the GI tract and leads to colonization of the upper airway tract with pathogenic species, potentially forming the biological basis for the observed increased incidence of pneumonia in these patients. This was a prospective observational study on patients (adults 18 years or older) admitted to the medical intensive care unit (MICU) at a tertiary care centre. Exclusion criteria included all patients with a diagnosis of pneumonia at admission, with infection in the upper airway, or with a history of significant dysphagia. Oropharyngeal cultures were obtained on day 1 and days 3 or 4 of admission. We collected data on demographics, clinical information, and severity of the underlying disease using APACHE II scores. There were 110 patients enrolled in the study. The mean age was 49±16 years, 50 were women, and the mean APACHE II score was 9.8 ± 6.5. Twenty per cent of the patients had used a PPI in the month preceding admission. The first oropharyngeal specimen was available in 110 cases; a second specimen at 72-96 h was available in 68 cases. Seventy-five per cent of the patients admitted to the MICU had abnormal flora. In multivariate logistic regression, diabetes mellitus and PPI use were associated with abnormal oral flora on admission. Chronic renal failure and a higher body mass index reduced the frequency of abnormal oral flora on admission. Most critically ill patients admitted to our MICU have abnormal oral flora. Patients with diabetes and a history of recent PPI use are more likely to have abnormal oral flora on admission.

    To estimate the prevalence of fluoroquinolone-resistant rectal flora in patients undergoing transrectal ultrasound-guided prostate needle biopsy and to identify the high-risk groups. From January 2015 to March 2016, rectal swabs of 557 men who underwent transrectal ultrasound-guided prostate needle biopsy were obtained from five institutions. Clinical variables, including demographics, rectal swab culture results and infectious complications, were evaluated. Univariable and multivariable analyses were used to identify the risk factors for fluoroquinolone resistance of rectal flora and infectious complications. The incidence of fluoroquinolone-resistant and extended-spectrum beta-lactamase production was 48.1 and 11.8%, respectively. The most common fluoroquinolone-resistant bacteria was Escherichia coli (81% of total fluoroquinolone-resistant bacteria, 39% of total rectal flora), and 16 (2.9%) patients had infectious complications. Univariable and multivariable analysis of clinical parameters affecting fluoroquinolone resistance showed no factor associated with fluoroquinolone resistance of rectal flora. The clinical parameter related to infectious complications after prostate biopsy was a history of operation within 6 months (relative risk 6.60; 95% confidence interval 1.99-21.8, P = 0.002). These findings suggest that a risk-based approach by history taking cannot predict antibiotic resistance of rectal flora, and physicians should consider targeted antibiotic prophylaxis or extended antibiotic prophylaxis for Korean patients undergoing transrectal ultrasound-guided prostate biopsy because of high antibiotic resistance of rectal flora. © 2017 The Japanese Urological Association.

  18. Forum on stakeholder confidence: Spain

    The FSC workshop in Spain provided an important opportunity to carry out an in-depth examination of decision-making processes undertaken in an NEA member country, and to reflect on the evolution that has taken place over time. It offered a well-rounded perspective on the inclusion of stakeholders in decision making, and the atmosphere of the meetings was conducive to an honest and open exchange of ideas. The workshop started with the introduction of two case studies: the earlier attempt in Spain to locate a potential site for a high-level waste (HLW) disposal facility, and the dismantling of the Vandellos-I nuclear power plant. This was followed by two days of presentations and round-table discussions based on the recent COWAM Spain initiative (stemming from the EU-wide project on Community Waste Management), which aims at developing recommendations for institutional arrangements and decision-making processes concerning the siting of waste management facilities in Spain. This article provides a brief summary of the case studies and the COWAM Spain initiative, followed by some of the lessons learnt from an international perspective. (authors)

    Full Text Available The association between worm infections and bacterial diseases has only recently been emphasized. This study examined the effect of experimental Angiostrongylus costaricensis infection on endogenous intestinal flora of Swiss Webster mice. Eight mice aging six weeks were selected for this experiment. Four were infected with A. costaricensis and the other four were used as controls. Twenty eight days after the worm infection, all mice in both groups were sacrificed and samples of the contents of the ileum and colon were obtained and cultured for aerobic and anaerobic bacteria. In the mice infected with A. costaricensis there was a significant increase in the number of bacteria of the endogenous intestinal flora, accompanied by a decrease in the number of Peptostreptococcus spp. This alteration in the intestinal flora of mice infected by the nematode may help to understand some bacterial infections described in humans.

    Recurrent vaginal candidiasis (RVC) is considered to be a hypersensitivity disorder that is associated with allergic rhinitis (AR) in immune deficiencies; however, whether or not the composition of the vaginal fungal flora in patients with AR and RVC is altered and if such alterations in patients with AR are associated with the development of RVC remain unclear. In the present study, a cultivation-independent method with the 18S rRNA gene clone library was used to analyze the diversity and composition of the vaginal fungal flora in patients with AR and RVC and to explore the association. Three fungal phyla (Ascomycotae, 22 out of 28; Basidiomycetes, 5 out of 28; and Oomycetes, 1 out of 28) were identified from groups of healthy volunteers, patients with AR, patients with RVC, and patients with RVC complicated by AR, including 28 phylotypes of fungal flora (10, 15, 17, and 21 phylotypes for each group, respectively). The predominant genera of fungi identified in the vagina included Candida, uncultured fungi, and Dothideomycetes. An increased proportion of Candida albicans accompanied with decreased proportions of Saccharomyces cerevisiae and uncultured fungi was observed in patients with AR or RVC (P vaginal fungal diversity in patients with AR or RVC was significantly higher compared with healthy volunteers (P vaginal fungal flora in patients with AR and RVC and indicated that disturbed vaginal fungal flora in patients with AR might be correlated with disease progression in patients with RVC.

    Oleuropein is a phenolic compound of olive leaves. Enteric bacterial flora is very important for human health and diet is a directly affecting factor of enteric bacterial flora composition. In this study, it was hypothesized that oleuropein could reduce total aerobic bacterial count in rat caecal flora. Twenty adult, male, Wistar albino rats were randomly divided into two groups. Group C (n=10) was fed with standard rat chow and water for 30 days. Group O (n=10) received olive leaf extract 20 mg/kg/day by intragastric gavage in addition to standard rat chow and water for 30 days. One gram of caecal content was collected from each rat and then consecutive 10-fold serial dilutions were prepared with a final concentration of 10-8. Then 0.1 ml of each dilution were spread onto the surfaces of Plate Count Agar and Violet Red Bile Glucose Agar to enumerate the aerobic enteric bacteria. Total aerobic bacterial counts of Group O were significantly lower than of Group C in all agar plates inoculated with ceacal samples for every dilution (pbacterial translocation by reducing enteric bacterial counts (Tab. 1, Ref. 32).

    Full Text Available Rural tourism businesses have experienced a very remarkable growth in recent times, providing regions with large opportunities to develop economically and socially. Part of the success of these businesses is due to the search of quality in the services they provide. In this work the influence of various dimensions of total quality orientation on staff satisfaction, communication and commitment in this tourist sector are analysed. The sample was made up of staff from hotels and restaurants in the mountainous area of “Sierra de Aracena y Picos de Aroche” in the province of Huelva, using Gómez-Bernabeu’s Quality and Culture Questionnaire for data collection. By means of linear regressions it was observed that the dimensions of acknowledgement and continuous improvement have an influence on communication, while development and training of human resources would be the best predictor of job satisfaction. Nevertheless, no conclusive data were obtained regarding organizational commitment.

    Full Text Available En este artículo exploraremos un escenario ambiental específico: Huelva, una ciudad en el sur de España, enormemente contaminada por unas plantas industriales y químicas establecidas durante los años sesenta del pasado siglo, y construidas en las proximidades de la ciudad, en lo que podríamos llamar su patio trasero (“backyard”. Examinaremos este caso a través de una perspectiva de green criminology, identificando las cuestiones teóricas y los enfoques metodológicos que pueden adoptarse cuando se estudia un caso de crimen medioambiental todavía vigente como el que se presenta aquí. Nuestra investigación se desarrollará partiendo de preguntas como: ¿Qué opinan y cómo se sienten los habitantes de la zona afectada cuando describen el problema de la contaminación y de las consecuencias empíricas de este crimen medioambiental? ¿Cuáles son las cuestiones decisivas que, más allá de los límites de las definiciones legales de crimen, y de las aproximaciones criminologícas tradicionales, plantean tales narraciones? En el transcurso de la investigación, tendremos que observar, examinar y analizar las interacciones entre los seres humanos y el medio ambiente en el que habitan, más aún en los casos en los que estas interacciones se nos revelen insatisfactorias, frustrantes y llenas de riesgos catastróficos. También desde esta perspectiva, un posible enfoque del daño social implica una transformación de las relaciones sociales y medioambientales destructivas.

    2008-06-01

    Full Text Available The endemic vascular flora of the Canary Islands comprises over 680, taxa collectively accounting for more than 50% of the total native flora. To investigate geographical patterns of diversity within the endemic flora, distribution data from published sources together with other field observation and herbarium data were used to compile a data matrix comprising the distributions of ca. 90% of endemic taxa scored on a 10 × 10km UTM grid. WORLDMAP was then used to investigate patterns of endemic diversity, range size rarity (a measure of endemicity, phylogenetic diversity and threatened taxon richness. Endemic taxon richness was found to be highly heterogeneous across the archipelago, with cells containing between one and 139 taxa each (0.05-22.82% of endemic diversity. Patterns of variation in range size rarity and phylogenetic diversity were found to be largely congruent with endemic diversity, although some cells exhibited markedly higher range size rarity scores than would be predicted by their endemic diversity scores. In contrast, the pattern of endangered taxon richness across the archipelago differed markedly from endemic taxon richness. Many cells in Lanzarote, Fuerteventura and Gran Canaria exhibit higher endangered taxon richness scores than would be predicted from their endemic richness scores whereas in Tenerife, El Hierro, La Palma and La Gomera, the converse is generally true. The implications of the results both for understanding the evolution of Canary Island endemic diversity and for the conservation of the region’s unique and vulnerable flora are considered.La flora vascular endémica de las Islas Canarias comprende unos 680 táxones, lo que viene a representar más del 50% de la flora nativa.

    The gut is an important target organ of injury during critically ill conditions. Although Gram staining is a common and quick method for identifying bacteria, its clinical application has not been fully evaluated in critically ill conditions. This study's aims were to identify patterns of Gram-stained fecal flora and compare them to cultured bacterial counts and to investigate the association between the patterns and septic complications in patients with severe systemic inflammatory response syndrome (SIRS). Fifty-two patients with SIRS were included whose Gram-stained fecal flora was classified into three patterns. In a diverse pattern, large numbers of multiple kinds of bacteria completely covered the field. In a single pattern, one specific kind of bacteria or fungi predominantly covered the field. In a depleted pattern, most bacteria were diminished in the field. In the analysis of fecal flora, the numbers of total obligate anaerobes in the depleted pattern was significantly lower than those in the diverse pattern and single pattern (p Gram-stained fecal flora can be classified into three patterns and are associated with both cultured bacterial counts and clinical information. Gram-stained fecal bacteria can be used as a quick bedside diagnostic marker for severe SIRS patients.

  2. Plateau hypoxia attenuates the metabolic activity of intestinal flora to enhance the bioavailability of nifedipine.

    Nifedipine is completely absorbed by the gastrointestinal tract and its pharmacokinetics and metabolism may be influenced by microorganisms. If gut microbes are involved in the metabolism of nifedipine, plateau hypoxia may regulate the bioavailability and the therapeutic effect of nifedipine by altering the metabolic activity of the gut microbiota. We herein demonstrated for the first time that gut flora is involved in the metabolism of nifedipine by in vitro experiments. In addition, based on the results of 16S rRNA analysis of feces in rats after acute plateau, we first confirmed that the plateau environment could cause changes in the number and composition of intestinal microbes. More importantly, these changes in flora could lead to a slower metabolic activity of nifedipine in the body after an acute plateau, resulting in increased bioavailability and therapeutic efficacy of nifedipine. Our research will provide basis and new ideas for changes in the fecal flora of human acutely entering the plateau, and contribute to rational drug use of nifedipine.

    Assessing the demand for radiotherapy in Spain based on existing evidence to estimate the human resources and equipment needed so that every person in Spain has access to high-quality radiotherapy when they need it. We used data from the European Cancer Observatory on the estimated incidence of cancer in Spain in 2012, along with the evidence-based indications for radiotherapy developed by the Australian CCORE project, to obtain an optimal radiotherapy utilisation proportion (OUP) for each tumour. About 50.5 % of new cancers in Spain require radiotherapy at least once over the course of the disease. Additional demand for these services comes from reradiation therapy and non-melanoma skin cancer. Approximately, 25-30 % of cancer patients with an indication for radiotherapy do not receive it due to factors that include access, patient preference, familiarity with the treatment among physicians, and especially resource shortages, all of which contribute to its underutilisation. Radiotherapy is underused in Spain. The increasing incidence of cancer expected over the next decade and the greater frequency of reradiations necessitate the incorporation of radiotherapy demand into need-based calculations for cancer services planning.

    Introduction Four potential meteorite-dropping events happened over Spain during 2007. All them are being carefully studied in the framework of the SPanish Meteor Network (SPMN). Due to the large range of visibility of these events, they usually appear far away from the recording stations, or in broad daylight. The later was the case of the most remarkable of these events: the diurnal bolide witnessed by thousands of people in the afternoon of May 10, at 17h57m01±5s UTC. That magnificent daylight event produced the Puerto Lápice meteorite, an eucrite with a total known weight of about 500 grams [1, 2]. Other wonderful event happened during the afternoon of March 2, 2007 at 18h51m06±1s UTC: a magnificent bolide (Fig. 1) was seen over the Pyrenees by several eyewitnesses located in Catalonia and Aragon, but also from the South of France. Unfortunately it was not recorded by SPMN stations and a very limited number of visual reports were received. Figure 1. The appearance of the March 2, 2007 bolide as drawn made by the second author and fortunate eyewitness from Sant Celoni (Barcelona). Another potential meteorite-dropping diurnal bolide was witnessed from several locations over the south of Spain on the afternoon of June 29. A sonic boom was reported by witnesses located near from the estimated impact area, in the province of Huelva (Andalusia). In some cases these also reported that the bolide generated electrophonic sounds and that the sonic boom was accompanied by vibration of objects inside their houses. However, despite several expeditions to the impact area have been made, the meteorite produced by this bolide has not been found yet. This is mainly due to the high uncertainty in the calculation of the impact point, as the region is quite unpopulated and just about a dozen of eyewitnesses could be interviewed. On the other hand, the characteristics of the vegetation that grows in the area also poses important difficulties to the search tasks. Besides, as in

  11. Variations in atmospheric PM trace metal content in Spanish towns: Illustrating the chemical complexity of the inorganic urban aerosol cocktail

    Science.gov (United States)

    Moreno, Teresa; Querol, Xavier; Alastuey, Andrés; Viana, Mar; Salvador, Pedro; Sánchez de la Campa, Ana; Artiñano, Begoña; de la Rosa, Jesús; Gibbons, Wes

    The majority of the Spanish urban population breathe air containing inhalable ambient airborne particles at average concentrations of 30-46 μg m -3 (PM 10) and 20-30 μg m -3 (PM 2.5). Even though the average weight of inhaled urban aerosol is commonly similar, however, there can be large chemical differences between the ambient dusts from different towns, including the more bioreactive elements such as some metals. In this context, we compare the source-apportioned trace metal content of airborne PM 10 and PM 2.5 collected daily over a 1-year period from six population centres in Spain: Barcelona, Alcobendas, Llodio, Huelva, Tarragona and Las Palmas de Gran Canaria. Total average trace metal (ΣTM) PM 10 and PM 2.5 contents vary by up to a factor of around 3, reaching a maximum of ΣTM 10 811 ng m -3 and ΣTM 2.5 503 ng m -3 at Llodio, an industrial but humid site with the lowest PM 10 mass levels but high contamination by Zn, Pb, Mn, Sn, Ni and Cr. In contrast, pollution at Huelva, although another industrially influenced site, instead emphasises Cu and As, whereas Barcelona, where traffic emissions and resuspension contribute to some of the highest average PM 10 levels in Spain, has unusually raised levels of Ti, V and Ba. Such variations in both daily and annual average PM bulk chemistry, particularly in potentially toxic trace metals concentrated in the finer aerosols (such as Cd, As, Pb, Hg and Ni), predict that PM health effects on resident populations from different towns are unlikely to be the same.

    This finalized research project on the fungal flora of forest stands under severe stress form immissions looked into the question of the contribution of fungi to the triggering of topical forest damage and investigated whether correlations between certain symptoms and needle yellowing or root damage can be established. The main tree species selected were spruce and pine; but spot sample checks were also carried out on other tree species. Fungal flora was determined both qualitatively and quantitatively, and the pathogenic significance of the individual species was determined. Further, it was investigated whether fungal species are correlated to certain symptoms of damage, and which fungal species are. For selected fungal species, their pathogenicity was investigated by infection experiments. (RHE) [de

    This paper analyzes organizational and marketing changes occurring in Spain's oil industry as a result of its conversion from a state run monopoly system to a free market system. The analysis uses statistical data to indicate national oil production, import and consumption trends and compares these with overall trends in the European Communities. An explanation of the way in which oil is marketed in Spain makes reference to data on Spain's refining capacity and pipeline network, deemed to be amongst the most complete and modern in Europe. Comments are also made on the efficacy of Spain's national energy policies which stress energy source diversification to lessen this country's heavy dependence on foreign supplied oil

  8. Future of endemic flora of biodiversity hotspots in India.

    Directory of Open Access Journals (Sweden)

    Vishwas Sudhir Chitale

    Full Text Available India is one of the 12 mega biodiversity countries of the world, which represents 11% of world's flora in about 2.4% of global land mass. Approximately 28% of the total Indian flora and 33% of angiosperms occurring in India are endemic. Higher human population density in biodiversity hotspots in India puts undue pressure on these sensitive eco-regions. In the present study, we predict the future distribution of 637 endemic plant species from three biodiversity hotspots in India; Himalaya, Western Ghats, Indo-Burma, based on A1B scenario for year 2050 and 2080. We develop individual variable based models as well as mixed models in MaxEnt by combining ten least co-related bioclimatic variables, two disturbance variables and one physiography variable as predictor variables. The projected changes suggest that the endemic flora will be adversely impacted, even under such a moderate climate scenario. The future distribution is predicted to shift in northern and north-eastern direction in Himalaya and Indo-Burma, while in southern and south-western direction in Western Ghats, due to cooler climatic conditions in these regions. In the future distribution of endemic plants, we observe a significant shift and reduction in the distribution range compared to the present distribution. The model predicts a 23.99% range reduction and a 7.70% range expansion in future distribution by 2050, while a 41.34% range reduction and a 24.10% range expansion by 2080. Integration of disturbance and physiography variables along with bioclimatic variables in the models improved the prediction accuracy. Mixed models provide most accurate results for most of the combinations of climatic and non-climatic variables as compared to individual variable based models. We conclude that a regions with cooler climates and higher moisture availability could serve as refugia for endemic plants in future climatic conditions; b mixed models provide more accurate results, compared to single

    Kruuse, A.

    1992-01-01

    The report examines the effects of forest energy on the field layer vegetation, and includes whole-tree harvesting, liming, fertilization, wood ash distribution and the importance of broadleaved trees. Whole-tree harvesting is negative for some of the vascular plant species, and positive for others, and can have a drastically negative effect on lichens, mosses and decomposing fungi. Whole-tree harvesting can be accepted from the viewpoint of the flora if: - between 10 and 30 % of the slash is left on the clearcut area, - hardwood stands or mixed stands with hardwood are excepted from whole-tree harvesting, - dead lying or standing trees, a few broadleaved trees and old trees, are left on the clearcut area. Liming has some effects on the flora, especially a very negative effect on lichens and mosses. Liming can be accepted if; - it only takes place where whole-tree harvesting has been used or where acidification caused by air pollution has been observed, - the amounts are moderate, 2 to 4 tonnes/ha, and the liming material has a rather large grain size, - it is unevenly distributed, and - it is avoided in naturally acid stands with a special vegetation. Fertilization has negative effects on all the considered vegetation groups. It can only be accepted as compensation for whole-tree harvesting, and no more nitrogen must be added than is taken away in the harvest. In southern Sweden even the compensatory fertilization should be avoided. The consequences of wood ash distribution are little known. Until more facts are presented, only enough wood ash as to compensate for the loss through whole-tree harvesting should be distributed. If the use of forest energy would lead to an increase of the broadleaved tree ratio it would be positive. (54 refs.)

  14. Interrelationships Within the Bacterial Flora of the Female Genital Tract

    Directory of Open Access Journals (Sweden)

    Henry J. Carson

    1997-01-01

    Full Text Available Analysis of 240 consecutive vaginal swabs using the compatibility profile technique revealed that only 2 bacteria have the ability to be a sole isolate and as such a candidate to be a major aerobic regulator of the bacterial flora of the female genital tract (BFFGT. Compatibility profiles of Lactobacillus and Gardnerella vaginalis have shown that these organisms shared compatibility profiling for the majority of the normal bacterial constituents of the female genital tract. Dominance disruption appears to come from the addition of compatible co-isolates and presumed loss of numerical superiority. These phenomena appear to be the keys to reregulation of BFFGT. Lactobacillus appears to be the major regulator of both G. vaginalis and anaerobic bacteria. When additional organisms are added to the bacterial flora, they may add to or partially negate the inhibitory influence of Lactobacillus on the BFFGT. Inhibitor interrelationships appear to exist between coagulase-negative staphylococci and Staphylococcus aureus and the group B streptococci (GBS and other beta hemolytic streptococci. Facilitating interrelationships appear to exist between S. aureus and the GBS and selected Enterobacteriaceae.

    The aim of this study was to compare the significance of the intestinal hydrolysis of prenylated flavonoids in Herba Epimedii by an intestinal enzyme and flora. Flavonoids were incubated at 37 °C with rat intestinal enzyme and intestinal flora. HPLC-UV was used to calculate the metabolic rates of the parent drug in the incubation and LC/MS/MS was used to determine the chemical structures of metabolites generated by different flavonoid glycosides. Rates of flavonoid metabolism by rat intestinal enzyme were quicker than those of intestinal flora. The sequence of intestinal flora metabolic rates was icariin>epimedin B>epimedin A>epimedin C>baohuoside I, whereas the order of intestinal enzyme metabolic rates was icariin>epimedin A>epimedin C>epimedin B>baohuoside I. Meanwhile, the LC/MS/MS graphs showed that icariin produced three products, epimedin A/B/C had four and baohuoside I yielded one product in incubations of both intestinal enzyme and flora, which were more than the results of HPLC-UV due to the fact LC/MS/MS has lower detectability and higher sensitivity. Moreover, the outcomes indicated that the rate of metabolization of flavonoids by intestinal enzyme were faster than those of intestinal flora, which was consistent with the HPLC-UV results. In conclusion, the metabolic pathways of the same components by intestinal flora and enzyme were the same. What's more, an intestinal enzyme such as lactase phlorizin hydrolase exhibited a more significant metabolic role in prenylated flavonoids of Herba Epimedi compared with intestinal flora.

    Twenty-two consecutive patients with cancer of the head and neck, who were to receive a full tumoricidal dose of irradiation to a field that included the oral cavity and pharynx, were studied to determine the effect of the irradiation on their local bacterial flora. Aerobic cultures were taken prior to, at the completion of, and one month after the completion of their irradiation. The percentage of patients with potentially pathogenic organisms increased dramatically as the effect of the irradiation increased. This change in the local flora has obvious implications concerning the increased incidence of postoperative wound infections in patients who have received prior irradiation

    Microbial flora can provide insight into the ecology and natural history of wildlife in addition to improving understanding of health risks. This study examines the anaerobic oral flora of hunter killed black bears (Ursus americanus) in eastern North Carolina. Oral swabs from the buccal and lingual supragingival tooth surfaces of the first and second mandibular and maxillary molars of 22 black bears were inoculated onto Brucella Blood Agar plates supplemented with hemin and vitamin K after transport from the field using reduced oxoid nutrient broth. Sixteen anaerobic bacterial species, representing nine genera were identified using the RapID ANA II Micromethod Kit system and a number of organisms grown that could not be identified with the system. The most frequently identified anaerobes were Peptostreptococcus prevotii, Streptococcus constellatus, and Porphyromonas gingivalis. The diversity in the anaerobic oral flora of black bear in eastern North Carolina suggests the importance of including these organisms in basic health risk assessment protocols and suggests a potential tool for assessment of bear/habitat interactions.

  20. Hydrodynamic characteristics of the western Doñana Region (area of El Abalario), Huelva, Spain

    Science.gov (United States)

    Trick, Thomas; Custodio, Emilio

    The Doñana region, in southwestern Spain, comprises a large and important nature reserve, the wetlands of which are affected by human activity. Planting of an extensive eucalyptus forest in the 1950s and, more recently, the use of aquifers for irrigation and water supply for some coastal tourist resorts, have altered the natural groundwater-flow system. The area of the study is the western sector of the region, called El Abalario, which is a gentle topographic elevation between the Atlantic coast and La Rocina Creek (Arroyo de la Rocina). Underneath a variable layer of eolian sands with high dunes near the coast, thick Plio-Quaternary detritic strata, mostly fine silica sands, overlie marls. Near the base there is a variable, deltaic-origin layer of coarse sands and gravels. The dome-shaped water table, inside the sands, is close to the surface everywhere except beneath the dune belt, and small, temporary, shallow lagoons are numerous. The coarse sand and gravel layer conditions groundwater flow and behaves as a semiconfined layer between sands. A cross section through the area was simulated with a model to check the validity of the conceptual groundwater-flow pattern and its sensitivity to the hydraulic parameters. The model was calibrated using parameter values obtained by pumping tests and multilevel piezometric data, and checked against the estimated groundwater discharge into La Rocina Creek. Groundwater flows peripherally to the sea coast, to La Rocina Creek, or directly east and southeastward into the Doñana marshlands, in the Guadalquivir River delta. The average net aquifer recharge rate was calculated to be between 100 and 200 mm year-1 for the area covered by brush, but is remarkably lower in the areas of eucalyptus trees. The transient-state model shows that recharge varies spatially and is not clearly proportional to annual precipitation. Phreatic evapotranspiration plays an important role in decreasing the net value of aquifer recharge to

    Full Text Available Changes in the flora composition of the eastern and southern shore area of Lake Piaseczno, with predominantly agricultural and recreational land use in the lake catchment, were examined in the years 2003 and 2010. Multifaceted analysis of the flora was made with regard to its botanical, syntaxonomical, and ecological aspects, the identified species were assigned to different historical-geographical groups and range groups, as well as the flora synanthropisation, anthropophytisation and apophytisation indices were calculated and compared. Both the species number and the species floristic composition of the Lake Piaseczno shore zone changed in seven years. The fact that the value of the synanthropisation index remained at a similar level and a slight increase in the anthropophytisation index values are probably related to the decrease in tourist traffic in this area and the diminishing pressure from extensive agriculture. The results of the flora analysis, in terms of the assignment of species to characteristic ecological groups, confirm the specific habitat conditions in the study area and, above all, significant permeability of the substrate and high soil nutrient availability.

  6. Quantitative methods in ethnobotany and ethnopharmacology: considering the overall flora--hypothesis testing for over- and underused plant families with the Bayesian approach.

    2011-09-01

    We introduce and explain the advantages of the Bayesian approach and exemplify the method with an analysis of the medicinal flora of Campania, Italy. The Bayesian approach is a new method, which allows to compare medicinal floras with the overall flora of a given area and to investigate over- and underused plant families. In contrast to previously used methods (regression analysis and binomial method) it considers the inherent uncertainty around the analyzed data. The medicinal flora with 423 species was compiled based on nine studies on local medicinal plant use in Campania. The total flora comprises 2237 species belonging to 128 families. Statistical analysis was performed with the Bayesian method and the binomial method. An approximated χ(2)-test was used to analyze the relationship between use categories and higher taxonomic groups. Among the larger plant families we find the Lamiaceae, Rosaceae, and Malvaceae, to be overused in the local medicine of Campania and the Orchidaceae, Caryophyllaceae, Poaceae, and Fabaceae to be underused compared to the overall flora. Furthermore, do specific medicinal uses tend to be correlated with taxonomic plant groups. For example, are the Monocots heavily used for urological complaints. Testing for over- and underused taxonomic groups of a flora with the Bayesian method is easy to adopt and can readily be calculated in excel spreadsheets using the excel function Inverse beta (INV.BETA). In contrast to the binomial method the presented method is also suitable for small datasets. With larger datasets the two methods tend to converge. However, results are generally more conservative with the Bayesian method pointing out fewer families as over- or underused. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    2016-01-01

    Abstract Background The systematic analysis of a large number of comparable plant trait data can support investigations into phylogenetics and ecological adaptation, with broad applications in evolutionary biology, agriculture, conservation, and the functioning of ecosystems. Floras, i.e., books collecting the information on all known plant species found within a region, are a potentially rich source of such plant trait data. Floras describe plant traits with a focus on morphology and other traits relevant for species identification in addition to other characteristics of plant species, such as ecological affinities, distribution, economic value, health applications, traditional uses, and so on. However, a key limitation in systematically analyzing information in Floras is the lack of a standardized vocabulary for the described traits as well as the difficulties in extracting structured information from free text. Results We have developed the Flora Phenotype Ontology (FLOPO), an ontology for describing traits of plant species found in Floras. We used the Plant Ontology (PO) and the Phenotype And Trait Ontology (PATO) to extract entity-quality relationships from digitized taxon descriptions in Floras, and used a formal ontological approach based on phenotype description patterns and automated reasoning to generate the FLOPO. The resulting ontology consists of 25,407 classes and is based on the PO and PATO. The classified ontology closely follows the structure of Plant Ontology in that the primary axis of classification is the observed plant anatomical structure, and more specific traits are then classified based on parthood and subclass relations between anatomical structures as well as subclass relations between phenotypic qualities. Conclusions The FLOPO is primarily intended as a framework based on which plant traits can be integrated computationally across all species and higher taxa of flowering plants. Importantly, it is not intended to replace established

    Directory of Open Access Journals (Sweden)

    2009-01-01

    Full Text Available There are numerous parameters that can influence bacterial decontamination during washing of machinery and equipment in a food processing establishment. Incomplete decontamination of bacteria will increase the risk of biofilm formation and consequently increase the risk of pathogen contamination or prevalence of other undesirable microorganisms such as spoilage bacteria in the processing line. The efficiency of a typical washing protocol has been determined by testing three critical parameters and their effects on bacterial decontamination. Two surface materials (plastic and stainless steel, water temperatures (7 and 25 °C and detergent concentrations (2 and 4 % were used for this purpose in combination with two types of detergents. Biofilm was prepared on the surfaces with undefined bacterial flora obtained from minced cod fillets. The bacterial flora of the biofilm was characterised by cultivation and molecular analysis of 16S rRNA genes. All different combinations of washing protocols tested were able to remove more than 99.9 % of the bacteria in the biofilm and reduce the cell number from 7 to 0 or 2 log units of bacteria/cm2. The results show that it is possible to use less diluted detergents than recommended with comparable success, and it is easier to clean surface material made of stainless steel compared to polyethylene plastic.

    2011-02-01

    In order to describe the normal bacterial flora in vaginas of Criollo Limonero cows, 51 healthy multiparous cows, at least 90-day postpartum, were selected. Duplicated swabs (N = 102) were taken from the vaginal fornix of cows to perform aerobic and anaerobic cultures as well as conventional biochemical tests. Out of 102 swabs, bacterial growth was obtained in 55 (53.9%) while the remaining 47 (46.1%) did not exhibited any bacterial growth. Of the 55 bacterial growths, 23 (41.8%) were aerobic whereas 32 (58.1%) were anaerobic. Likewise, 29 (52.72%) of bacterial growths were pure and 26 (47.27%) were mixed. Under both aerobic and anaerobic conditions, Gram positive bacteria were predominant (81.82% and 73.08%, respectively) over Gram negative bacteria (18.18% and 26.92%, respectively). Isolated bacteria were Arcanobacterium pyogenes (22.92%), Staphylococcus aureus (15.63%), Staphylococcus coagulase negative (17.71%), Erysipelothrix rhusiopathiae (6.25%), Bacteroides spp. (13.54%), and Peptostreptococcus spp. (7.29%). In conclusion, normal vaginal bacterial flora of Criollo Limonero cows was predominantly Gram positive and included A. pyogenes, S. aureus, coagulase negative Staphylococcus, E. rhusiopathiae, Bacteroides spp., and Peptostreptococcus spp. In Criollo Limonero cattle, adaptive aspects such as development of humoral and physical mechanisms for defense, and bacterial adaptation to host deserve research attention.

  1. Spain: Success story in space

    Science.gov (United States)

    Longdon, Norman

    From the early 1960's, European governments were aware that they had to take part in the exploration, and potential exploitation, of space, or be left behind in a field of high-technology that had far-reaching possibilities. It was also realized that financial and manpower constraints would limit the extent to which individual nations could carry out their own national programs. They, therefor, joined forces in two organizations: the European Space Research Organization (ESRO) and the European Launcher Development Organization (ELDO). By 1975, when the potential of space development had been more fully appreciated, the two organizations were merged into the Europeans Space Agency (ESA) of which Spain was a founding member. ESA looks after the interest of 13 member states, one associated member state (Finland), and one cooperating state (Canada) in the peaceful uses of space. Its programs center around a mandatory core of technological research and space science to which member states contribute on the basis of their Gross National Product. Spain in 1992 contributes 6.46% to this mandatory program budget. The member states then have the chance to join optional programs that include telecommunications, observation of the earth and its environment, space transportation systems, microgravity research, and participation in the European contribution to the International Space Station Freedom. Each government decides whether it is in its interest to join a particular optional program, and the percentage that it wishes to contribute to the budget. Although in the early days of ESA, Spain participated in only a few optional programs, today Spain makes a significant contribution to nearly all of ESA's optional programs. This document presents Spain's contributions to particular ESA Programs and discusses Spain's future involvement in ESA.

    Full Text Available The paper presents the results of investigations on the flora of fallow lands on rendzina soils. The research was carried out in the area of the Twardowice Plateau (the Silesian Upland within 9 areas adjacent to xerothermic grasslands. The investigated flora consisted of 220 vascular plant species with the dominance of native taxa. Plants of xerothermic grasslands and thermophilous edges were the most numerous (32%. The dominance of Libanotis pyrenaica in 4 of the examined areas should be emphasized. The percentage of meadow species was also considerable (25%. Anthropophytes comprised 18% of the flora of fallow lands and archaeophytes prevailed among them (9%. Solidago canadensis, an invasive species, was the constant component of the investigated fallows and sometimes its coverage was remarkable. As a result of the high proportion of xerothermic and thermophilous plants, plants associated with dry soils and soils having an intermediate character between dry and fresh, as well as plants preferring slightly acidic to alkaline soils poor in nitrogen compounds predominated in the investigated fallows. Perennial plants prevailed (65% in the studied flora and slightly more than half of the species reproduced only by seeds. Competitive plant species (C strategists had the highest proportion (39% and species with intermediate strategies CSR, CR and CS were also numerous. The investigations have shown that there are favourable conditions for settling and growth of many xerothermic species in the investigated fallow lands. Moreover, the neighbouring grasslands are the seed source for these areas.

    Full Text Available A floristic inventory of segetal flora was carried out in abandoned fields and adjacent crop fields on rendzina soils in the Zamość region in the year 2010. This study found a total of 130 weed species belonging to 30 botanical families. The following families were represented most frequently: Asteraceae, Fabaceae, Poaceae, Lamiaceae, Scrophulariaceae, and Brassicaceae. In the segetal flora, apophytes are dominant (55% of the total flora, with the highest number of meadow and xerothermic grassland species among them. Archeophytes (38% predominate in the group of anthropophytes. The species characterized by the highest constancy classes and reaching the highest cover indices posed the greatest threat to crops in the study area. The following weeds are most frequently found in fallow fields: Consolida regalis, Cichorium intybus, and Sinapis arvensis, while Papaver rhoeas is the greatest threat to cereal crops grown on rendzina soils.

    Full Text Available The aim of this research was to evaluate the effect of the inoculation date of arbuscular mycorrhizal fungi on the fruit quality and the content of phytochemicals in a strawberry soilless growing system. The experiment was performed in Huelva (Spain and was conducted in a greenhouse on the La Rábida Campus of Huelva University under natural light and temperature from October 2013 to June 2014. Three short-day strawberry cultivars (‘Splendor’, ‘Sabrina’ and ‘Fortuna’ were grown in polyethylene bags filled with coconut fibres. Randomized block design, with 3 repetitions and factorial arrangement (3 cultivars x 3 treatments, was established. Each replicate consisted of one bag with 12 plants supporting structures at 40 cm height. The treatments were: T1 = mycorrhizal inoculation in the transplantation; T2 = mycorrhizal inoculation 30 days after transplantation (DAT; and T0 = control treatment, without inoculation. Arbuscular mycorrhizal fungi inoculation significantly affected the contents of anthocyanin and phenolics. When the inoculation is performed in the transplantation, the fruits showed a high content of anthocyanin and total phenolics. The mycorrhizal inoculation influences decreasing the acidity in fruit throughout the growing season and increase firmness only during the early stage of production.

    2013-04-01

    The overall aim of this study was to describe uterine bacterial flora during the postpartum period in Danish Holstein cows using the Terminal Restriction Fragment Length Polymorphism (T-RFLP) method. This method produces a pattern of nucleic acid fragments from the microorganisms present, reflecting the "fingerprint" of the actual microbial flora. As well as characterizing changes in flora with time from calving and between herds, data were examined for strong relations between uterine bacterial flora, calving management and uterine condition. In total 125 Holstein cows from five herds were included, and for each cow calving management was recorded. Cows were clinically examined on average 8 (range 0-19) and 28 (range 22-38) days after calving, and a uterine sample was taken for bacterial identification using T-RFLP. Milk samples were taken weekly for progesterone analysis. Bacteria were found in all cows at both examinations, and the flora was composed of many species, including species not traditionally reported to be present in the bovine uterus. The bacterial composition differed according to days from calving and herd. In all five herds Fusobacterium necrophorum, Pseudomonas/Acinetobacter and Bacteroides/Sphingobacterium/Prevotellaceae were among the most common at both examinations. In four herds there was a percentage decrease of F. necrophorum from first to second examination, and in all herds there was a percentage increase of Pseudomonas/Acinetobacter from first to second examination. No differences in bacterial flora were found between cows with different uterine scores, which were influenced by herd, calving difficulty and retained placenta. Copyright © 2013 Elsevier B.V.

    Cross-linked hyaluronic acid (HA) gel is widely used in esthetic medicine. Late bacterial infection (LBI) is a rare, but severe complication after HA augmentation. The aim of this study was to determine whether patients who underwent the HA injection procedure and developed LBI had qualitatively different bacterial flora on the skin compared to patients who underwent the procedure without any complications. The study group comprised 10 previously healthy women with recently diagnosed, untreated LBI after HA augmentation. The control group comprised 17 healthy women who had a similar amount of HA injected with no complications. To assess the difference between the two groups, their skin flora was cultured from nasal swabs, both before and after antibiotic treatment in the study group. A significant increase in the incidence of Staphylococcus epidermidis was detected in the control group ( P =0.000) compared to the study group. The study group showed a significantly higher incidence of Staphylococcus aureus ( P =0.005), Klebsiella pneumoniae ( P =0.006), Klebsiella oxytoca ( P =0.048), and Staphylococcus haemolyticus ( P =0.048) compared to the control group. The bacterial flora on the skin differed in patients with LBI from the control group. The control group's bacterial skin flora was dominated by S. epidermidis . Patients with LBI had a bacterial skin flora dominated by potentially pathogenic bacteria.

    Current geographic patterns of biodiversity are a consequence of the evolutionary history of the lineages that comprise them. This study was aimed at exploring how evolutionary features of the vascular flora of Chile are distributed across the landscape. Using a phylogeny at the genus level for 87% of the Chilean vascular flora, and a geographic database of sample localities, we calculated phylogenetic diversity (PD), phylogenetic endemism (PE), relative PD (RPD), and relative PE (RPE). Categorical Analyses of Neo- and Paleo-Endemism (CANAPE) were also performed, using a spatial randomization to assess statistical significance. A cluster analysis using range-weighted phylogenetic turnover was used to compare among grid cells, and with known Chilean bioclimates. PD patterns were concordant with known centers of high taxon richness and the Chilean biodiversity hotspot. In addition, several other interesting areas of concentration of evolutionary history were revealed as potential conservation targets. The south of the country shows areas of significantly high RPD and a concentration of paleo-endemism, and the north shows areas of significantly low PD and RPD, and a concentration of neo-endemism. Range-weighted phylogenetic turnover shows high congruence with the main macrobioclimates of Chile. Even though the study was done at the genus level, the outcome provides an accurate outline of phylogenetic patterns that can be filled in as more fine-scaled information becomes available.

    2016-04-01

    Identifying regions of high endemism is a critical step toward understanding the mechanisms underlying diversification and establishing conservation priorities. Here, we identified regions of high moss endemism across North America. We also identified lineages that contribute disproportionately to endemism and document the progress of efforts to inventory the endemic flora. To understand the documentation of endemic moss diversity in North America, we tabulated species publication dates to document the progress of species discovery across the continent. We analyzed herbarium specimen data and distribution data from the Flora of North America project to delineate major regions of moss endemism. Finally, we surveyed the literature to assess the importance of intercontinental vs. within-continent diversification for generating endemic species. Three primary regions of endemism were identified and two of these were further divided into a total of nine subregions. Overall endemic richness has two peaks, one in northern California and the Pacific Northwest, and the other in the southern Appalachians. Description of new endemic species has risen steeply over the last few decades, especially in western North America. Among the few studies documenting sister species relationships of endemics, recent diversification appears to have played a larger role in western North America, than in the east. Our understanding of bryophyte endemism continues to grow rapidly. Large continent-wide data sets confirm early views on hotspots of endemic bryophyte richness and indicate a high rate of ongoing species discovery in North America. © 2016 Botanical Society of America.

    The aim of the present study was to investigate the effect of Probiotics in Progress (PIP) on the establishment of a competitive flora as well as on antibiotic use and losses of suckling piglets in pig breeding farms. The tested products were PIP AHC® and PIP AHS® produced by "Chrisal AG" in Lommel, Belgium. PIP`s are cleaning products containing Bacillus spores. According to the manufacturer's specifications, they are able to establish a steady non-pathogenic stable flora. In a field trial in 19 pig breeding farms, the use of PIP-products did not lead to any reduction of antibiotic use or improvement of fertility parameters, especially in relation to losses of suckling piglets. In addition, we compared the bacterial flora using PIP products with the flora under conventional management conditions in a farrowing pen by means of swab samples. The use of PIP-products did not lead to any significant effect on the pen flora. Only very few swab samples contained a majority of probiotic Bacillus spp.

    An ecological study of the yeasts present in a spontaneous and an inoculated fermentation in red wine was carried out in 2005 vintage in a winery located in the Denomination of Origin "Sierras de Málaga" (Málaga, southern of Spain). The winery operated by the first time with the 2003 vintage and since then, has used commercial yeast inocula to start alcoholic fermentation. Yeast isolates were identified by PCR-RFLP analysis of the 5.8S-ITS region from the ribosomal DNA and by mitochondrial DNA RFLP analysis. Except for non-Saccharomyces yeasts found in the fresh must before fermentation, all the isolates were found to be commercial Saccharomyces cerevisiae strains employed by the winery during the successive vintages; thus, no indigenous Saccharomyces yeasts were isolated during fermentation. The same four restriction patterns were found in non inoculated and inoculated vats, although with different frequencies. The use of commercial yeast starter in a new established winery seems to have prevented the development of a resident indigenous Saccharomyces flora.

    Full Text Available Zimbabwe’s casual, naturalised and invasive alien plant species were analysed with regard to their habit, origin, mode or purpose of introduction and their invasion status in the country. This alien flora of 391 taxa belonged to 239 genera and 73 families, corresponding to 6.6% of the total flora of Zimbabwe. Of these, 153 (39.1% plant species were casual aliens, 154 (39.4% were naturalised and 84 (21.5% were invasive species. Most invasions in terms of numbers of alien species were in the central and eastern parts of the country. Asteraceae (53 species, Poaceae (48 species and Fabaceae sensu lato (49 species families were prominent in all the floristic regions of the country. Annual and perennial herbaceous species formed the majority of life forms of the casual, naturalised and invasive alien flora of Zimbabwe. Genera with the highest number of alien species were Ipomoea with nine species, Acacia and Euphorbia with eight species each, Chenopodium and Senna with seven species each, Eucalyptus with six species, Oenothera, Physalis and Solanum with five species each. More than 49.6% of the alien plants in Zimbabwe originated primarily from South, Central and North America, followed by Europe (24.6%, Asia (23.8%, Africa (10.5% and Australasia (5.9%.Conservation implications: This research provides baseline information and historical invasion patterns of casual, naturalised and invasive alien flora in Zimbabwe. This inventory is a crucial starting point in trying to understand and initiate the management of biological invasions. This is also important for monitoring new introductions and management of existing alien plants in Zimbabwe.

    The Huelva Estuary in Huelva, Spain, has been one of the most studied environmental compartments in the past years from the point of view of naturally occurring radioactive material (NORM) releases. It has been historically affected by waste releases, enriched in radionuclides from the U-decay series, from factories located in the area devoted to the production of phosphoric acid and phosphate fertilizers. Nevertheless, changes in national regulations forced a new waste management practice in 1998, prohibiting releases of phosphogypsum into the rivers. The input of natural radionuclides from phosphate factories to rivers was drastically reduced. Because of this there was a unique opportunity for the study of the response of a contaminated environmental compartment, specifically an estuary affected by tidal influences, after the cessation of the contaminant releases to, in this case, the Huelva Estuary (henceforth referred to as the Estuary). To investigate the environmental response to this new discharge regime, the specific activities of radionuclides 226 Ra and 210 Pb in water and sediment samples collected in four campaigns (from 1999 to 2005) were determined and compared with pre-1998 values. From this study it is possible to infer the most effective mechanisms of decontamination for the Estuary. Decontamination rates of 210 Pb and 226 Ra in the sediments and water have been calculated using exponential fittings and corresponding half-lives have been deduced from them. The cleaning half-life in the whole area of the Estuary is about 6 and 3.5 years for 226 Ra and 210 Pb respectively. The observed trend clearly shows that contamination of the Estuary by natural radionuclides is now decreasing and radioactive levels in waters and sediments are approaching the natural background references. This work attempts to evaluate whether it can be expected that the decontamination of the enhanced levels of natural radioactivity in the Estuary can be performed via natural

    Full Text Available Kenya, an African country with major higher plant diversity, has a corresponding diversity of plant associations, because of the wide geographic distribution, diverse climatic conditions and soil types. In this article, all vascular plants of Kenya were counted based on the completed "Flora of Tropical East Africa (FTEA", and all families and genera were revised using recent molecular systematics research, forming a "Synoptic List of Families and Genera of Kenyan Vascular Plants (SLFGKVP". In total, there are 225 families, 1538 genera and 6293 indigenous species and and 62 families, 302 genera and 588 exotic species in Kenya. The Fabaceae with 98 genera and 576 Species is the largest family. Two of the seven plant distribution regions of Kenya, K4 and K7 are the most species-richest areas with regard to both total and endemic species, with 3375 and 3191 total species and 174 and 185 endemic species in K4 and K7 respectively. While, K3 and K5 have the highest density of both total and endemic species. K1 has the lowest density of total species, and K2 has the lowest density of endemic species.

    2014-03-01

    Full Text Available The present study focuses on the summary of recent and subrecent diatom flora within Sudeten mountain wetlands - the Jizerské Mts and the Jeseníky Mts Recent samples were taken during the years 2003 and 2006 - 2010. Herbarized bryophytes and fixed samples deposited in museums from the period 1898 - 1995 were used as a source of subrecent diatom flora. A total of 163 diatom species occurred at 70 microsites within 26 mires along the Czech-Polish-German border areas. Recent diatom flora of both areas seems to be comparable in terms of species richness and dominant species. Subrecent samples (herbarized bryophytes contain some less frequent species (representation < 1%, which do not belong to mire flora and can represent a contamination (e.g. planktic genera. Frustulia saxonica and Eunotia paludosa were the most frequent species. E. exigua related in Western Europe to acidification caused by acid rains, was less frequent in both historic and modern samples. Unfortunately, we have few historical herbarium specimens from the 70-ies and 80- ies to trace changes associated with air pollution.

  7. The vascular flora and floristic relationships of the Sierra de La Giganta in Baja California Sur, Mexico La flora vascular y las relaciones florísticas de la sierra de La Giganta de Baja California Sur, México

    José Luis León de la Luz

    2008-06-01

    Full Text Available The Sierra de La Giganta is a semi-arid region in the southern part of the Baja California peninsula of Mexico. Traditionally, this area has been excluded as a sector of the Sonoran Desert and has been more often lumped with the dry-tropical Cape Region of southern Baja California peninsula, but this classical concept of the vegetation has not previously been analyzed using formal documentation. In the middle of the last century, Annetta Carter, a botanist from the University of California, began explorations in the Sierra de La Giganta that lasted 24 years, she collected 1 550 specimens and described several new species from this area, but she never published an integrated study of the flora. Our objectives, having developed extensive collections in the same area over the past years, are to provide a comprehensive species list and description of the vegetation of this mountain range. We found a flora of 729 taxa, poorly represented in tree life-forms (3.1%, a moderate level (4.4% of endemism, and the dominance of plants in the sampling plots is composed mainly for legume trees and shrubs. Additionally, using a biogeographical approach, we compare our list with other known lists of plants from 5 areas, 3 in the Cape Region, 1 in the Sonoran Desert, and other in the thornscrub area of NW Mexico. We conclude that the La Giganta flora has a mixed composition, primarily made up of plants shared with the lowlands of the southern Cape Region, but also share an important proportion of the flora with the desert mountains of the central peninsula and some with the Sonoran desertscrub of mainland Mexico. Consequently we support that the La Giganta flora is part of a floristic continuum along the volcanic mountains of the southern peninsula that eventually could be considered a new eco-region in the same peninsular land.La sierra de La Giganta se localiza en el estado de Baja California Sur, México, en una región semi-árida.

    Various alien species have been introduced to the Ogasawara Islands (Japan). A survey was made investigating whether the native pollination systems fit an 'island syndrome' (biasing the flora to dioecy, with subdued, inconspicuous flowers) and whether alien species have disrupted the native pollination network. Flower visitors and floral traits were determined in the field (12 islands) and from the literature. Associations among floral traits such as sexual expression, flower colour and flower shape were tested. Among the 269 native flowering plants, 74.7 % are hermaphroditic, 13.0 % are dioecious and 7.1 % are monoecious. Classification by flower colour revealed that 36.0 % were white, 21.6 % green and 13.8 % yellow. Woody species (trees and shrubs) comprised 36.5 % of the flora and were associated with dioecy and white flowers. Solitary, endemic small bees were the dominant flower visitors and visited 66.7 % of the observed species on satellite islands where the native pollination networks are preserved. In contrast to the situation on the satellite islands, introduced honeybees were the most dominant pollinator (visiting 60.1 % of observed species) on the two main islands, Chichi-jima and Haha-jima, and had spread to satellite islands near Chichi-jima Island. The island syndrome for pollination systems in the Ogasawara Islands was evident in a high percentage of dioecious species, the subdued colour of the native flora and solitary flower visitors on satellite islands. The shape and colour adaptations of several flowers suggested native pollination niches for long-proboscis moths and carpenter bees. However, the domination and expansion of introduced honeybees have the potential for disruption of the native pollination network in the two main, and several satellite, islands of the Ogasawara Islands.

  9. Detection and analysis of endogenous badnaviruses in the New Zealand flora.

    Badnaviruses and their host-integrated DNA occur in tropical crops and a few northern temperate species. Following the discovery of a badnavirus on a subantarctic island with floristic links to New Zealand, we postulated that badnaviruses exist in the New Zealand flora. Badnavirus reverse transcriptase (RT) sequences consist of variable regions flanked by highly conserved regions. This study used RT sequences to detect and characterize badnavirus sequences in the New Zealand flora and to investigate their utility for the study of broader aspects of plant biology. Molecular diversity of RT sequences was analysed using polymerase chain reaction and denaturing gradient gel electrophoresis (DGGE). In a study of the genus Melicytus, internal transcribed spacer (ITS) sequences were compared with the RT data. No freely replicating badnaviruses were detected but more than half of the species (37/60) contained RT sequences. Phylogenetic analysis of 21 RT sequences formed monophyletic groups distinct from other species and from badnaviruses. No frameshift mutations occurred in any of the sequences translated in silico. More detailed study of the genus Melicytus indicated broader applications for our approach. Analysis of RT sequences revealed the presence of a previously unrecognized species (confirmed using ITS). Inheritance of DGGE profiles by Melicytus ramiflorus seedlings suggested that this species may undergo apomixis. The presence of integrated badnavirus sequences in a wide range of taxa from this Southern Hemisphere flora indicates that these sequences may be common in many temperate regions. Potential to activate viruses from these sequences should be considered when placing these species in tissue culture or under other forms of abiotic or genomic stress. Analysis of endogenous RT sequences shows potential for the study of systematics, phylogenetics and plant reproductive biology.

    To study the gut flora in infants who received fermented milk containing Lactobacillus casei and Streptococcus termophilus and its effect on secretory immunoglobulin levels. An experimental, randomized, prospective, parallel group study was carried out. Thirty-five infants were included (18 in the treatment group and 17 in the control group) with a mean age of 2 years (SD: 0.6 years; range: 1-3 years). The experimental group received both fermented milk (0.5 l/day) containing L. casei and S. termophilus for 6 weeks and standard cow's milk for the following 6 weeks. The control group received standard cow's milk (0.5 l/day) for 12 weeks. Secretory IgA levels in saliva were evaluated in the experimental group at the start of the study (baseline levels) and 6 weeks later. In both groups, stools were collected to study gut flora at 0, 6 and 12 week. Secretory IgA levels significantly increased (p =0.0063) from a mean baseline value of 2.5 mg/dl to a mean of 3.4 mg/dl at 6 weeks. Gram-negative aerobic flora were decreased in the experimental group after 6 weeks compared with the control group (p =0.0203). The number of infants with Lactobacillus spp in their gut flora was greater in the experimental group than in the control group at week 6 and this difference was statistically significant (p =0.028) at week 12. Conclusion The present study provides evidence of L. casei survival in the gastrointestinal tract and of its effect of increasing secretory IgA.

    Spain's nuclear generation capacity will be reduced by some 6000MWe by the year 2015 if decommissioning of the units currently in operation takes place at the end of their 40-year design life. Bearing this in mind, in 1988 the Santa Maria de Garona BWR and the Jose Cabrera PWR were chosen by their respective owners as reference units for plant life extension (PLEX) activities. These plants are the oldest of their types operating in Spain and PLEX programmes were already under way. (author)

  14. Overview of bryophyte flora research in Serbia with presentation of the Serbian BRYO database

    Pantović Jovana

    2017-10-01

    Full Text Available Bryophyte flora research in Serbia was rather sporadic until the end of the 19th century, when a group of mostly high-school teachers started researching bryophytes. This was the first fruitful period of exploration, with many new country records. Thereafter, not many researchers investigated bryophytes in Serbia, and the majority of chorological data came from vegetation, ecological, or palaeobotanical studies. This lasted until the 1990s, when a revival of bryophyte investigation occurred, bringing with it many floristic studies and new species records for the country. At the present time, Serbia is considered to be rich in bryophyte diversity, with as many as 797 species. However, further study and a critical approach to the bryophyte flora of Serbia are needed.

    Ethnopharmacological studies are important for the discovery of new drugs from reported indigenous flora. The current study was aimed to document medicinal flora and its therapeutic actions along with the relative importance in local health care system of the district of Vehari, Punjab province, Pakistan. Rapid appraisal approach (RAA) and semi structured interviews were used along with the group meetings with herbalists, local inhabitants and landowners to collect the relevant data. A total 77 medicinal plants belonging to 41 families disseminated among 71 genera were reported. Fabaceae was the predominant family over others with 9 reported medicinal plant species. Use frequency of leaves was at peak with 30.12% followed by stem 24.62%, fruit 14.22%, flower 12.97%, seeds 12.13%, bark 4.6% and pod 1.25%, in herbal preparations. Allium cepa exhibited the highest use value (0.90) while lowest use value (UV) was reflected by Aerva javanica (0.10). Documentation of various medicinal plants for the treatment of cancer, hepatitis and cardiac disorders is evidence in favor to highlight the value of medicinal flora. Unfortunately, no attention has been paid to this treasure in term of conservation and utilization in modern healthcare system, where these plants can be a best replacement of chemically synthesized drugs. It is also recommended that plants exhibiting high UV should be screened for detailed bio-active phytochemicals. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.
