    Background: Acanthaceae is one of the advanced and specialized families with conventionally used medicinal plants. Simple sequence repeats (SSRs) play a major role as molecular markers for genome analysis and plant breeding. The microsatellites existing in the complete genome sequences would help to attain a direct role in the genome organization, recombination, gene regulation, quantitative genetic variation, and evolution of genes. Objective: The current study reports the frequency of microsatellites and appropriate markers for the Acanthaceae family genome sequences. Materials and Methods: The whole nucleotide sequences of Acanthaceae species were obtained from National Center for Biotechnology Information database and screened for the presence of SSRs. SSR Locator tool was used to predict the microsatellites and inbuilt Primer3 module was used for primer designing. Results: Totally 110 repeats from 108 sequences of Acanthaceae family plant genomes were identified, and the occurrence of dinucleotide repeats was found to be abundant in the genome sequences. The essential amino acid isoleucine was found rich in all the sequences. We also designed the SSR-based primers/markers for 59 sequences of this family that contains microsatellite repeats in their genome. Conclusion: The identified microsatellites and primers might be useful for breeding and genetic studies of plants that belong to Acanthaceae family in the future. PMID:25709226

    Premise of the study: To assess the effect of forest fragmentation on genetic variation and population structure of Aphelandra aurantiaca (Acanthaceae), a tropical and ornamental herbaceous perennial plant, we developed the first microsatellite primers for the species. Methods and Results: Fourteen microsatellite markers were isolated and characterized from A. aurantiaca genomic libraries enriched for di-, tri-, and tetranucleotide repeat motifs. Polymorphism was evaluated in 107 individuals from four natural populations. Twelve out of 14 genetic markers were polymorphic. The number of alleles per locus ranged from two to 12, and the observed and expected heterozygosities ranged from 0.22 to 0.96 and from 0.20 to 0.87, respectively. Fixation indices ranged from ?0.41 to 0.44. Conclusions: These newly developed microsatellite markers for A. aurantiaca will be useful for future population genetic studies, specifically to detect the possible loss of genetic diversity due to habitat fragmentation.

    Comparative leaf micromorphology study was conducted in eight taxa of Acanthaceae from Peninsular Malaysia. Eight chosen taxa were Acanthus ebracteatus Vahl, A. ilicifolius L., A. volubilis Wall, A. montanus T. Anderson, Andrographis paniculata (Burm.f.) Wall. ex Nees, Asystasia gangetica subsp. micrantha (Nees) Ensermu, Chroesthes longifolia (Wight) B. Hansen and Peristrophe roxburghiana (Schult.) Bremek. The objective of this study was to identify the leaf micromorphological characteristics that can be used in species identification and also as supportive data in classification. The procedures involved such as dehydration, critical point drying, gold coated and examination under scanning electron microscope. Findings in this study have demonstrated the similarities and variations in leaf micromorphological characteristics such as in type of epicuticular waxes, cuticular ornamentations, stomata characteristics and in the presence of trichomes. Six types of epicuticular waxes and five types of trichomes were observed. Variations in cuticular ornamentations and stomata structure can be used to differentiate species. One diagnostic character was found and proven to be very useful to identify Acanthus via the presence of simple trichomes (short-conicle like). In conclusion, the results of this study have shown that leaf micromorphological characteristics have taxonomic significance that can be useful in classifications and identification especially at species level.

    Medicinal plants are used as a popular alternative to synthetic drugs, both in developed and developing countries. The economic importance of the herbal and natural supplement industry is increasing every year. As the herbal industry grows, consumer safety is one issue that cannot be overlooked. Herbal products in Thai local markets are commonly sold without packaging or labels. Plant powders are stored in large bags or boxes, and therefore buying local herbal products poses a high risk of acquiring counterfeited, substituted and/or adulterated products. Due to these issues, a reliable method to authenticate products is needed. Here DNA barcoding was used in combination with High Resolution Melting analysis (Bar-HRM) to authenticate three medicinal Acanthaceae species (Acanthus ebracteatus, Andrographis paniculata and Rhinacanthus nasutus) commonly used in Thailand. The rbcL barcode was selected for use in primers design for HRM analysis to produce standard melting profiles of the selected species. Melting data from the HRM assay using the designed rbcL primers showed that the three chosen species could be distinguished from each other. HRM curves of all fifteen test samples indicated that three of tested products did not contain the indicated species. Two closely related species (A. paniculata and R. nasutus), which have a high level of morphological similarity, were interchanged with one another in three tested products. Incorrect information on packaging and labels of the tested herbal products was the cause of the results shown here. Morphological similarity among the species of interest also hindered the collection process. The Bar-HRM method developed here proved useful in aiding in the identification and authentication of herbal species in processed samples. In the future, species authentication through Bar-HRM could be used to promote consumer trust, as well as raising the quality of herbal products. PMID:26011474

    Comparative anatomical study on flower petals was studied in four selected Justicia species from Peninsular Malaysia, i.e. J. comata (L.) Lam., J. carnea Lindl. J. betonica Linn. and J. procumbens L with the objective to provide useful data for species identification and differentiation within the genus of Justicia. Methods used in this study are mechanical scrapping on the leaf surfaces and observation under light microscope. Finding in this study has shown that all species are sharing similar type of anticlinal walls pattern, which is sinuous pattern. Two or more type of trichomes is present in all species studied and this character can be used to differentiate Justicia species. Simple multicellular trichomes are found to be present in all species studied. Justicia betonica can be isolated from other species by the existence of cyclo-paracytic stomata on the petal surfaces.

    The existence of the celestial bodies is known due to the light they emit. But light is a small part of a bigger phenomenon known as electromagnetic radiation. The representation of all kinds of electromagnetic radiation as a function of its frequency is called the electromagnetic spectrum. If we only studied the visible part of the spectrum, we would ignore a great deal of information. The celestial bodies emit radiation in all the regions of the electromagnetic spectrum, with very different intensity. To capture these data, astronomers design new types of telescopes that capture radiation at different wavelengths, among them the radiotelescopes that, as the name indicates, detect radio waves. The radiotelescope can be compared to a regular radio set. A radio station sends information by means of radio waves. The radio set captures these waves by means of its antenna, processes it and reproduces the information (music, etc.) in audible form. In the field of radioastronomy, interesting observations can be carried out: radio emission from stars, nebulas, pulsars, distant galaxies and stars, radiogalaxies, the Milky Way, the Sun, Jupiter, etc. La presencia de los cuerpos celestes se conoce gracias a que emiten luz. Pero la luz constituye solo una pequeña parte de un fenómeno mucho mas amplio conocido como radiación electromagnética. La representación de todas las clases de radiación como función de su frecuencia se denomina espectro electromagnético. Si solo estudiáramos la parte visual del espectro ignoraríamos una gran cantidad de información. Los cuerpos celestes emiten radiación en todas las regiones del espectro electromagnético, aunque con muy distinta intensidad. Para captar estos datos, los astrónomos deben diseñar nuevos tipos de telescopios que puedan captar la radiación de distintas longitudes de ondas, entre ellos los radiotelescopios, qué como su nombre lo indica detectan ondas de radio. El radiotelescopio puede compararse a un aparato de radio familiar. Una estación emisora está enviando información por medio de ondas de radio. El aparato de radio capta estas ondas mediante su antena, la procesa y el receptor reproduce la información (música, etc.) en forma audible. En el campo de la radioastronomía se pueden realizar observaciones interesantes: Radioestrellas, nebulosas, púlsares, galaxias y estrellas lejanas, radiogalaxias, la Vía Láctea, el Sol, Júpiter, etc.

    Many recent studies have suggested that the majority of animal-pollinated plants have a higher diversity of pollinators than that expected according to their pollination syndrome. This broad generalization, often based on pollination web data, has been challenged by the fact that some floral visitors recorded in pollination webs are ineffective pollinators. To contribute to this debate, and to obtain a contrast between visitors and pollinators, we studied insect and bird visitors to virgin flowers of Hypoestes aristata in the Bamenda Highlands, Cameroon. We observed the flowers and their visitors for 2-h periods and measured the seed production as a metric of reproductive success. We determined the effects of individual visitors using 2 statistical models, single-visit data that were gathered for more frequent visitor species, and frequency data. This approach enabled us to determine the positive as well as neutral or negative impact of visitors on H. aristata’s reproductive success. We found that (i) this plant is not generalized but rather specialized; although we recorded 15 morphotaxa of visitors, only 3 large bee species seemed to be important pollinators; (ii) the carpenter bee Xylocopa cf. inconstans was both the most frequent and the most effective pollinator; (iii) the honey bee Apis mellifera acted as a nectar thief with apparent negative effects on the plant reproduction; and (iv) the close relationship between H. aristata and carpenter bees was in agreement with the large-bee pollination syndrome of this plant. Our results highlight the need for studies detecting the roles of individual visitors. We showed that such an approach is necessary to evaluate the pollination syndrome hypothesis and create relevant evolutionary and ecological hypotheses. PMID:23593135

    Objective. The objective of this study was to find out the possible antiulcer mechanism of action of Eremomastax speciosa. Method. Carbachol- and histamine-induced hypersecretion, associated with the pylorus ligation technique, were used in rats. Gastric mucosal ulceration, mucus production, pH, gastric volume, and acidity were measured. Results. Histamine and carbachol raised gastric acidity to 86.50 and 84.80?mEq/L, respectively, in the control rats, and the extracts (200?mg/kg) reduced gastric acidity to 34.60 and 39.00?mEq/L, respectively. Intraduodenal aqueous extract (400?mg/kg) in histamine- and carbachol-treated rats produced significant (P < 0.001) decreases in acid secretion to 28.50 and 28.80?mEq/L, respectively, and 100 percent inhibition of gastric ulceration. Augmented histamine-induced gastric acid secretion (90.20?mEq/L) was significantly reduced to 52.60 and 27.50?mEq/L by the 200 and 400?mg/kg doses of the aqueous extract, respectively. The extract significantly reduced (P < 0.001) the volume of gastric secretion and significantly increased mucus production. The ulcer inhibition potential of the extract significantly dropped to 25–44% (oral extract) and to 29–37% (duodenal extract) in carbachol/indomethacin-treated rats. Conclusion. The aqueous extract of E. speciosa has both cytoprotective and antisecretory effects. The antisecretory effect may involve a mechanism common to both cholinergic and histaminergic pathways.

    Se han obtenido observaciones desde Tierra (H? y magnetogramas) coordinadas con el Soft X-ray Telescope (SXT), a bordo del satélite japonés Yohkoh, de una región activa bipolar en decaimiento. Estos datos constituyen la base para el estudio de un punto brillante en rayos X (PBX) y de la actividad relacionada con el mismo en distintas capas de la atmósfera solar. Las observaciones muestran que el PBX está relacionado con la aparición de un bipolo menor (~ 1020 Mx) y que su abrillantamiento continuo, así como sus aumentos de brillo esporádicos (``fulguraciones"), son el resultado de la reconexión entre el pequeño arco emergente (visto en H? como un sistema de filamentos arqueados, SFA) y arcos mayores asociados al campo facular preexistente. Se ha extrapolado el campo magnético observado en la aproximación libre de fuerzas lineal y se ha seguido su evolución a lo largo de la vida del PBX. Se ha calculado la posición de las cuasiseparatrices (CSs) a partir del campo modelado. Las líneas de campo extrapoladas, cuyas bases fotosféricas se encuentran a ambos lados de las CSs, están de acuerdo con las estructuras cromosféricas y coronales observadas. Se ha calculado el espesor de la CD ubicada a lo largo de la polaridad negativa emergente, encontrándose que su variación está de acuerdo con la evolución de la intensidad del PBX; la CS es muy delgada durante la vida del PBX (~ 100 m), mientras que su espesor aumenta considerablemente (>= 10^4 m) cuando el PBX desaparece de las imágenes del SXT. Estos resultados señalan que el abrillantamiento y las ``fulguraciones" de este PBX se deben al proceso de reconexión en 3D que tiene lugar en las CSs.

  14. Environmental control of reproductive phenology and the effect of pollen supplementation on resource allocation in the cleistogamous weed, Ruellia nudiflora (Acanthaceae)

    2012-01-01

    •?Background and Aims Mixed reproductive strategies may have evolved as a response of plants to cope with environmental variation. One example of a mixed reproductive strategy is dimorphic cleistogamy, where a single plant produces closed, obligately self-pollinated (CL) flowers and open, potentially outcrossed (CH) flowers. Frequently, optimal environmental conditions favour production of more costly CH structures whilst economical and reliable CL structures are produced under less favourable conditions. In this study we explore (1) the effect of light and water on the reproductive phenology and (2) the effect of pollen supplementation on resource allocation to seeds in the cleistogamous weed Ruellia nudiflora. •?Methods Split-plot field experiments were carried out to assess the effect of shade (two levels: ambient light vs. a reduction of 50 %) and watering (two levels: non-watered vs. watered) on the onset, end and duration of the production of three reproductive structures: CH flowers, CH fruit and CL fruit. We also looked at the effect of these environmental factors on biomass allocation to seeds (seed weight) from obligately self-pollinated flowers (CL), open-pollinated CH flowers and pollen-supplemented CH flowers. •?Key Results CH structures were produced for a briefer period and ended earlier under shaded conditions. These conditions also resulted in an earlier production of CL fruit. Shaded conditions also produced greater biomass allocation to CH seeds receiving extra pollen. •?Conclusions Sub-optimal (shaded) conditions resulted in a briefer production period of CH structures whilst these same conditions resulted in an earlier production of CL structures. However, under sub-optimal conditions, plants also allocated more resources to seeds sired from CH flowers receiving large pollen loads. Earlier production of reproductive structures and relatively larger seed might improve subsequent success of CL and pollen-supplemented CH seeds, respectively. PMID:22095920

    Introducción: El síndrome de outlet torácico es una compresión del plexo braquial que suscita polémica. Se clasifica en Outlet Torácico Verdadero o neurogénico (OTV) y Outlet Torácico Disputado o no neurogénico (OTD). El primero presenta síntomas motores en la mano, mientras que el segundo sólo síntomas sensitivos en el miembro superior. El objetivo de este trabajo es analizar los resultados obtenidos en una serie de 31 cirugías. Métodos: Se analizaron las cirugías de nervios efectuadas entre 2003-2012, tomando los diagnósticos de outlet torácico cuyo período de seguimiento post-operatorio mínimo fuera de 6 meses. Se buscaron los siguientes datos: edad, sexo, presencia de síntomas sensitivos y/o motores, clasificación, resultado de los estudios neurofisiológicos y de imágenes, resultado de la cirugía, complicaciones post-operatorias y recidivas. Resultados: Se incluyeron 31 cirugías realizadas en 30 pacientes, 9 OTV (8 mujeres) de 24.3 años, y 21 con OTD (18 mujeres) de 37.4 años de edad en promedio. Un 90% presentaron alteraciones neurofisiológicas preoperatorias, y 66,6% imagenológicas. En el intraoperatorio, el 100% de los OTV presentó una alteración anatómica relacionada con la sintomatología, hecho observado sólo en el 36.7% de los OTD operados. El 87,5% de los OTV mejoraron sensitivamente, mientras que 77,7% mejoraron la atrofia. Por el contrario, 45.4% de los OTD mejoraron permanentemente, 36.3% no tuvieron cambios, 13.6% mejoraron transitoriamente y 4.5% (un caso) empeoró. Las complicaciones post-operatorias fueron más frecuentes aunque transitorias en el grupo de OTV (3 casos sobre 9 operados, 33.3%) que en los OTD (3 casos sobre 22, un 13.6%). Conclusión: El OTV suele mayormente mejorar luego de la cirugía, igual que el OTD aunque en una proporción mucho menor. Estos hallazgos coinciden con otros reportes recientes de esta patología.

    Introducción: los meningiomas del foramen óptico producen un rápido deterioro de la función visual aún cuando su tamaño es pequeño, por eso su diagnóstico y manejo difiere del resto de los meningiomas clinoideos. El propósito de este estudio es presentar la técnica y los resultados de nuestro manejo quirúrgico de meningiomas foraminales (MF). Pacientes y Métodos: se llevó a cabo una revisión de las historias clínicas de 47 pacientes con meningiomas primarios intraorbitarios. Se realizaron 52 cirugías en los pacientes con MF. Se empleó una craneotomía fronto-orbitaria, seguida de una descompresión extradural del canal óptico, resección del componente intraorbitario y exploración intradural del nervio óptico. Resultados: de los 12 pacientes con MF que presentaban la visión conservada, la agudeza visual fue preservada en 7 casos, mejoró en 2, y empeoró en 3. En 18 pacientes, el principal síntoma fue exoftalmos y en 35 pacientes ceguera unilateral. Ocurrieron 6 recurrencias, 2 a 10 años después de la resección quirúrgica. Cinco de ellos fueron reoperados. Se indicó radioterapia después de la recurrencia en 3 pacientes. Conclusión: el manejo de los MF continúa siendo controvertido y frecuentemente se propone un tratamiento conservador. Basados en nuestros hallazgos de frecuente extensión intracraneal, proponemos realizar una resección total o subtotal del tumor, preservando el nervio óptico en pacientes con visión prequirúrgica conservada.

    Cirigliano, D.; Vial, J.-C.; Rovira, M.

    Observaciones del disco solar y de una protuberancia quiescente en el rango de longitudes de onda ultravioleta fueron obtenidas con el instrumento CDS (Coronal Diagnostic Spectrograph) y SUMER (Solar Ultraviolet Measurements of emitted radiation) a bordo de la sonda SOHO. El propósito es investigar las velocidades macroscópicas de varias especies metálicas que se observan tanto en el disco solar como en el plasma de las protuberancias. Para calcular las velocidades del disco solar aplicamos una técnica mixta para modelar la distribución de estructuras en UV en el Sol quieto. Las velocidades macroscópicas en las protuberancias se calcularon a partir de los corrimientos Doppler en cada línea espectral y luego se tomaron las del disco solar como referencia. Obtuvimos valores absolutos para las velocidades macroscópicas entre 5 y 40 km/seg. También detectamos comportamientos diferentes en las velocidades de las protuberancias en el centro con respecto a los bordes.

    Se llevó a cabo una investigación en acción con los propósitos de 1) documentar las relaciones de las tecnologías de la información y la comunicación en las clases de ciencias de escuela intermedia como elemento de apoyo cuando se aborda el tema ambiental y sus conceptos pertinentes, a partir de las observaciones de la investigadora, así como las entrevistas y diarios reflexivos de los estudiantes de una escuela intermedia en la zona metropolitana, y luego 2) diseñar una unidad instruccional sobre el tema ambiental que integre actividades tecnologías para el curso de ciencias de la escuela intermedia según el modelo PROCIC y las observaciones que hayan iniciado los estudiantes participantes. Finalmente, se plantearon las implicaciones educativas para el currículo del Programa de Ciencias al instrumentar este modelo de unidad mediante PROCIC, e integrado la tecnología y el tema ambiental. Los hallazgos se analizaron y se categorizaron de acuerdo con las preguntas de investigación. El hallazgo principal de la investigación aborda las cuatro relaciones centrales en las que se articula la utilización de las tecnologías y sus aplicaciones en la clase de ciencias. Estas cuatro relaciones que recogen la posición de los estudiantes son: 1) Perspectiva de los estudiantes hacia la tecnología. 2) Participación de los estudiantes en los aspectos docentes. 3) Aprendizaje estudiantil sobre el ambiente, y 4) Conciencia ambiental en relación con la vida diaria. Estas relaciones ponen de manifiesto,cómo se plantea en las implicaciones, la necesidad de más investigación en acción en la sala de clases, la importancia—como tema transversal—de la conciencia ambiental mediante la tecnología al construir conocimientos significativos dentro y fuera de la escuela, asó como, valorar la investigación y la dialogicidad en la sala de clases como actividades que obligan al reexamen de la práctica didáctica en su formas curriculares de objetivos, recursos, actividades, evaluación, entre otros. Estos planteamientos definen la unidad curricular que se propone en el cuatro capítulo.

    Abstract Cytogenetic analyses using C-banding and chromosomal digestion by several restriction enzymes were carried out in four populations (named A, B, C and D) of Hypostomus prope unae (Loricariidae, Hypostominae) from Contas river basin, northeastern Brazil. These populations share 2n=76 and single NORs on the second metacentric pair but exclusive karyotype forms for each locality. Populations A and B presented conspicuous terminal and interstitial heterochromatic blocks on most of acrocentric chromosomes and equivalent to NORs with differences in both position and bearing pair. Population D showed evident marks at interstitial regions and interspersed with nucleolar region while population C presented interstitial and terminal heterochromatin segments, non-coincident with NORs. The banding pattern after digestion with the endonucleases Alu I, Bam HI, Hae III and Dde I revealed a remarkable heterogeneity within heterochromatin, allowing the identification of distinctive clusters of repeated DNA in the studied populations, besides specific patterns along euchromatic regions. The analysis using restriction enzymes has proved to be highly informative, characterizing population differences and peculiarities in the genome organization of Hypostomus prope unae. PMID:24260639

    Mayaro and Una viruses (MAYV, UNAV) are mosquito-borne alphaviruses that may cause an acute febrile illness characterized by headache, retro-orbital pain, and rash that may progress to a severe and prolonged arthralgia. MAYV was first isolated in Trinidad in 1954, and UNAV was first identified in northern Brazil in 1959. Since then, numerous isolates of these agents have been made from humans, wild vertebrates, and mosquitoes in several countries in northern South America. Serological evidence suggests that these viruses are also present in portions of Central America. Because little is known about the natural transmission cycle of MAYV and virtually nothing is known about UNAV transmission, 63 isolates covering the known geographic and temporal ranges were used in phylogenetic analyses to aid in understanding the molecular epidemiology. Approximately 2 kb from the E1 and E2 glycoprotein genes and the complete 3' non-coding region were sequenced. Phylogenetic analyses of these sequences indicated that two distinct genotypes of MAYV exist with a distinct clade consisting exclusively of UNAV (previously designated as a subtype of MAYV). One MAYV genotype (genotype D) contains isolates from Trinidad and the northcentral portion of South America including Peru, French Guiana, Surinam, Brazil, and Bolivia. All of these isolates are highly conserved with a nucleotide divergence of < 6%. The second MAYV genotype (genotype L) contains isolates only from Brazil that are highly conserved (< 4% nucleotide divergence) but are quite distinct (15-19%) from the first genotype isolates. These analyses provide possible explanations for the natural ecology and transmission of MAYV and UNAV. PMID:16968922

    A neutralizing antibody (NTAb) survey on UNA and Mayaro viruses in black howler monkeys (Aloutta caraya) from subtropical regions of Argentina and Paraguay was carried out. Risk factors for infection in monkeys were analyzed. No positive sera for Mayaro virus were detected. A prevalence of 73% (61/84) of NTAb against UNAV was detected with titers ranging from 20 to 1280. According to the statistical analysis performed, the monkey's age was a significant risk factor, but not the origin or sex. This is the first report of Alouatta caraya infection by UNAV and the first record of its activity in Paraguay. PMID:17658571

Uno de los principales contaminantes del aire es el material particulado menor de 2,5 ? (PM 2,5), en la ciudad de Lima, anualmente 2300 muertes prematuras son atribuibles a este contaminante. Otro problema es la contaminación del aire domiciliario por el uso de cocinas con combustible de biomasa, donde la exposición excesiva a PM 2,5 dentro de las casas es responsable de aproximadamente 3000 muertes prematuras anuales entre adultos, con otro número desconocido de muertes entre niños debido a infecciones respiratorias. La contaminación del agua tiene como principales causas los desagües vertidos directamente a los ríos, minerales (arsénico) de varias fuentes, y fallas de las plantas de tratamiento. En el Perú, el cambio climático puede impactar en la frecuencia y severidad del fenómeno de El Niño oscilación del sur (ENSO) que se ha asociado con un incremento en los casos de enfermedades como cólera, malaria y dengue. El cambio climático incrementa la temperatura y puede extender las áreas afectadas por enfermedades transmitidas por vectores, además de tener efecto en la disponibilidad del agua y en la contaminación del aire. En conclusión, el Perú, pasa por una transición de factores de riesgo ambientales, donde coexisten riesgos tradicionales y modernos, y persisten los problemas infecciosos y crónicos, algunos de los cuales se asocian con problemas de contaminación de agua y de aire.

    El proposito de la investigacion fue evaluar la efectividad de una actividad de aprendizaje basado en la argumentacion dialogica en linea y su incidencia en el desarrollo de competencias cientificas. Se fundamenta en la teoria del aprendizaje socio cultural de Vigotsky (1984), los principios del diseno instruccional de la cognicion situada por Hung y Der-Thang (2001) y como estrategia se aplico la argumentacion dialogica utilizando el Modelo Argumentativo de Toulmin MAT (1984). El diseno experimental comparo dos grupos de estudiantes A y B en el curso virtual de Biotecnologia. El grupo A (experimental) desarrollo la discusion a partir de la estrategia disenada para este estudio y el grupo B (control) realizo la discusion desde las actividades tradicionales. El desarrollo de la competencia argumentativa se valoro con el instrumento de evaluacion para argumentacion dialogica en linea propuesta por Clark y Sampson (2008). La evaluacion de las competencias cientificas se realizo a partir de una postprueba. Los datos fueron analizados con pruebas estadisticas no parametricas. Los resultados de la investigacion, indicaron diferencias significativas en el nivel de la competencia argumental en el grupo experimental en comparacion al grupo control. Igualmente se demostro que existe una relacion positiva entre el nivel de desarrollo de la competencia argumentativa y el nivel de desarrollo de las competencias cientificas.

    This work is the result of the analysis of existing information in the earthquake database of the Observatorio Sismológico y Vulcanológico de Costa Rica, Universidad Nacional (OVSICORI-UNA), and seeks disclosure of basic seismological information recorded and processed in 2010. In this year there was a transition between the software used to record, store and locate earthquakes. During the first three months of 2010, we used Earthworm (http://folkworm.ceri.memphis.edu/ew-doc), SEISAN (Haskov y Ottemoller, 1999) and Hypocenter (Lienert y Haskov, 1995) to capture, store and locate the earthquakes, respectively; in April 2010, ANTELOPE (http://www.brtt.com/software.html) start to be used for recording and storing and GENLOC (Fan at al, 2006) and LOCSAT (Bratt and Bache 1988), to locate earthquakes. GENLOC was used for local events and LOCSAT for regional and distant earthquakes. The local earthquakes were located using the 1D velocity model of Quintero and Kissling (2001) and for regional and distant earthquakes IASPEI91 (Kennett and Engdahl, 1991) was used. All the events for 2010 and shown in this work were rechecked by the authors. We located 3903 earthquakes in and around Costa Rica and 746 regional and distant seismic events were recorded (see Figure 1). In this work we also give a summary of major earthquakes recorded and located by OVSICORI-UNA network between 1983 and 2012. Seismicity recorded by OVSICORI-UNA network in 2010

    Water is one of the most vital natural resource and its availability and quality determine ecosystem productivity, both for agricultural and natural systems. Una district is one of the major potential agricultural districts in Himachal Pradesh, India. More than 70% of the population of this district is engaged in agriculture and allied sectors and major crops grown are maize, wheat, rice, sugarcane, pulses and vegetables. The region faces drought every year and about 90 per cent of the area is water stressed. This has resulted in crop loss and shortage of food and fodder. The sources of drinking water, small ponds and bowlies dry-up during summer season resulting in scarcity of drinking water. Una district receives rainfall during monsoons from June to September and also during non-monsoon period (winter). The annual average rainfall in the area is about 1040 mm with 55 average rainy days. But due to heavy surface run-off the farmers not able to cultivate the crops more than once in a year. Past research indicate that the geomorphology of the Una district might be responsible for such droughts as it controls the surface as well as ground water resources. The research proposes to develop a water stress model for Una district using the geomorphic parameters, water resource and land use land cover data of the study area. Using Survey of India topographical maps (1:50000), the geomorphic parameters are extracted. The spatial layers of these parameters i.e. drainage density, slope, relative relief, ruggedness index, surface water body's frequency are created in GIS. A time series of normalized remotely sensed data of the study area is used for land use land cover classification and analyses. Based on the results from the water stress model, the drought/water stress areas and water harvesting zones are identified and documented. The results of this research will help the general population in resolving the drinking water problem to a certain extent and also the cultivators to water the crops more than twice per year which might increase the crop yield in Una district.

    RESUMEN Durante la década de 1990 en los Estados Unidos (EU), el conocimiento sobre el trastorno de estrés post-traumático (TEPT) evolucionó de estudios específicos en un principio, sobre veteranos de guerra y sobre víctimas de desastres, a estudios epidemiológicos más tarde, sin embargo, la epidemiología del TEPT en países en desarrollo ha sido un área poco estudiada hasta ahora. Los expertos en el área de trauma han propuesto que los sucesos traumáticos que ocurren en la niñez son más perjudiciales para la salud mental que aquellos que ocurren más tarde en la vida. Este trabajo revisa los resultados de un estudio epidemiológico llevado a cabo en Chile. Específicamente, se revisan los resultados sobre las tasas de prevalencia del TEPT, traumas asociados más frecuentemente con él, así como la comorbilidad de este trastorno con otros trastornos psiquiátricos a lo largo de la vida. Igualmente se analizaron las diferencias del TEPT en cada sexo, así como la exposición a traumas en una muestra representativa de chilenos. Además se comparó la prevalencia de trastornos psiquiátricos en personas que sufrieron su primer trauma durante la niñez, durante la edad adulta, o que no reportaron traumas durante su vida. En estos estudios epidemiológicos se usaron módulos del TEPT y trastorno de personalidad antisocial (TPA) de la entrevista diagnóstica siguiendo los criterios del DSM-III-R (DIS–III-R). Para evaluar el resto de los trastornos psiquiátricos se usó la Entrevista Diagnóstica Internacional Compuesta (CIDI). Estos instrumentos fueron administrados en tres ciudades chilenas a 2390 personas mayores de 15 años. Para estimar los errores estándares (EE) debido al diseño de la muestra y a la necesidad de ajuste se usó el método Taylor de linearización seriada. También se usó un análisis de regresión logística para examinar la relación entre el TEPT, los factores demográficos de riesgo y el tipo de trauma. Además se utilizó la regresión logística multivariada para evaluar si la relación entre el TEPT y el sexo pudiera ser explicada por medio de otros factores de riesgo, así como para calcular las tasas y la oportunidad relativa (razón de productos cruzados) de trastornos psiquiátricos a lo largo de la vida. El primer análisis arrojó que la prevalencia de TEPT a lo largo de la vida fue de 4.4% (2.5% para hombres y 6.2% para mujeres). De los hechos traumáticos reportados, la violación sexual tuvo una correlación más alta con el TEPT que los demás hechos traumáticos. Las mujeres tuvieron más probabilidades de experimentar TEPT que los hombres, después de controlar la variable asalto violento. El segundo análisis evidenció que los que habían sufrido traumas a lo largo de la vida tuvieron mayor probabilidad de tener un trastorno psiquiátrico en comparación con aquellos que no reportaron traumas. También se encontró que los que sufrieron su primer trauma durante la infancia tuvieron más probabilidad de desarrollar trastornos de pánico a lo largo de la vida que aquellos que sufrieron su primer trauma en la edad adulta, independientemente del número de traumas que sufrieron y de las diferencias demográficas. Aunque Chile tiene un contexto histórico-cultural y una economía diferente a otros países en los que se ha estudiado anteriormente la epidemiología del TEPT, el presente estudio reflejó tendencias similares a las reportadas en estudios previos. Los hallazgos expuestos enfatizan la importancia de investigar la prevalencia del TEPT, los patrones de comorbilidad del TEPT y las diferencias de sexo en la prevalencia del TEPT en diferentes países. También estos resultados sugieren que los sucesos traumáticos en la infancia

    We present a very simple concrete model to demonstrate the concept of phases of an illuminated body. The main objective of our model is to help the understanding of the Moon phases as viewed from the perspective of an observer on Earth. The material allows the visualization of two important effects: (1st) even though all the time half Moon is illuminated by the Sun, we see different fractions of the illuminated Moon surface, depending on our angle of sight; (2nd) the orientation of the convex part of the Moon in the crescent and waning phases on the sky also depends on our perspective from Earth. The use of a closed box allows one to see the contrast among the different phases with no need of a dark room. We also present a text on the Moon phases, emphasizing the dependence of the aspect of the bright part on the angle of sight. En este trabajo proponemos la construcción de material didáctico de bajo costo para demostración del concepto de fases de un cuerpo iluminado. El principal objetivo de nuestro material es facilitar la comprensión de las fases de la Luna desde la perspectiva de un observador en la Tierra. El material ayuda la visualización de dos efectos importantes: (1º) a pesar de tener siempre la mitad de la Luna (representada por una bolita de espuma plástica o de ping-pong), iluminada por el Sol ( representado por una fuente de luz natural o artificial), vemos diferentes fracciones de su superficie iluminada, dependiendo del ángulo por el cual la vemos; (2º) la orientación del borde convexo de la Luna en las fases Creciente y Menguante también depende de la perspectiva por la cual la miramos desde la Tierra. El uso de una caja cerrada permite observar el contraste entre las diferentes fases sin necesidad de estar en un recinto oscuro. Presentamos también un texto explicativo sobre las fases de la Luna, enfatizando la dependencia de la apariencia de la parte iluminada con el ángulo de visión. Neste trabalho propomos a construção de material didático de baixo custo para demonstração do conceito de fases de um corpo iluminado. O principal objetivo de nosso material é facilitar a compreensão das fases da Lua da perspectiva de um observador na Terra. O material ajuda na visualização de dois efeitos importantes: (1º) mesmo tendo sempre a metade da "Lua" (representada por uma bolinha de isopor ou de ping-pong) iluminada pelo "Sol" (representado por uma fonte de luz natural ou artificial), nós vemos diferentes frações de sua superfície iluminada, dependendo do ângulo pelo qual a olhamos; (2º) a orientação da borda convexa da Lua nas fases Crescente e Minguante também depende da perspectiva pela qual a olhamos da Terra. O uso de uma caixa fechada permite observar o contraste entre as diferentes fases sem necessidade de estar em uma sala escurecida. Apresentamos também um texto explicativo sobre fases da Lua, enfatizando a dependência da aparência da parte iluminada com o ângulo de visada.

    Torpedograss, Panicum repens L., is an adventive, rhizomatous grass species that has become an invasive weed of terrestrial, wetland, and aquatic environments in tropical and subtropical regions worldwide. Until recently, strategies for controlling torpedograss in the USA have focused almost exclusively on mechanical and chemical methods, either alone or in combination, with varied results. A survey of the arthropods and nematodes currently associated with the plant in Lake Okeechobee, Florida, was conducted as part of a feasibility study to determine whether torpedograss is an appropriate target for a classical biological control program. Overall, approximately 4,000 arthropods and 400 nematode specimens were collected. Sweep, clipped vegetation, and soil core samples were dominated by representatives of the arthropod orders Hemiptera, Hymenoptera, Diptera, and Acari. Lesion nematodes of the genus Pratylenchus were commonly associated with the roots of torpedograss. None of the organisms collected were torpedograss specialists. Although classical biological control of torpedograss is feasible based on the extent of the infestation, economic losses, resistance to conventional controls, and the report of a potentially host specific natural enemy in India, the botanical position of this grass weed will require a formal risk assessment before proceeding with a classical biological control program. (author) [Spanish] La conota, Panicum repens L., es una especie foranea de pasto que produce rizomas que ha convertido en ser una maleza invasora de ambientes terrestres, pantanosos y acuaticos en regiones tropicales y subtropicales en todo el mundo. Hasta hace un tiempo reciente, las estrategias para controlar conota en los EEUU eran enfocadas casi exclusivamente en los metodos mecanicos y quimicos, solos o en combinacion, con resultados variables. Un muestreo de los artropodos y nematodos asociados corrientemente con esta planta en el Lago de Okeechobee, Florida, fue realizado como parte de un estudio de factibilidad para determinar si conota es una candidata apropiada para un programa de control biologico clasico. En general, especimenes de aproximadamente unos 4,000 artropodos y unos 400 nematodos fueron recolectados. Muestras recolectadas pasando una red sobre vegetacion mezclada, cortando la vegetacion y tomando centros del suelo fueron dominados por representantes de artropodos de los ordenes de Hemiptera, Hymenoptera, Diptera, y Acari. Nematodos en el genero Pratylenchus, que causan lesiones sobre tejido, fueron asociados regularmente con las raices de conota. Ninguno de los organismos recolectados eran especialistas sobre conota. Aunque el control biologico clasico de la conota es factible basado sobre la magnitud de la infestacion, las perdidas economicas, la resistencia hacia los metodos de control convencionales y el informe en la India de un posible enemigo natural especifico a esta planta, la posicion botanica de este pasto maleza requiere una evaluacion de riesgo economico formal antes de continuar con un programa de control biologico clasico.

    This article aims to present the results of a diagnostic evaluation, used as a tool for collecting data on prior knowledge of scientific concepts needed to understand the topic "Earth and Universe", from a group comprised of 47 students of 6th grade. The educational method of diagnosing the student's prior knowledge before teaching them is founded on the Meaningful Learning theory, proposed by David Ausubel. The diagnostic evaluation consisted of 25 questions; the answers were analyzed and categorized, making possible their interpretation, which allows us to understand the meanings assigned by the student to these concepts. It follows from the diagnostic evaluation, that the majority of students surveyed had difficulties in exposing scientific concepts on the topic "Earth and Universe" when starting the 6th grade. However, we identified relevant ideas and representations that contributed to the re-signification of scientific concepts proposed for the teaching of the subject in this grade. The results of diagnostic evaluation served as reference to the organization of the syllabus, making possible the learning process by matching the sequence of teaching to the students" characteristics and context of the classroom. It is expected that other researchers in this topic can also use the instrument presented in this paper. Este artículo tiene como objetivo presentar los resultados de una evaluación diagnóstica, utilizada como una herramienta para recoger datos sobre el conocimiento previo de los conceptos científicos necesarios para comprender el tema "Tierra y Universo", de un grupo compuesto por 47 alumnos de 6º grado de la escuela primaria. La acción pedagógica del diagnóstico de los conocimientos previos del estudiante antes de enseñarles está justificada por la teoría del Aprendizaje Significativo, propuesta por David Ausubel. La evaluación de diagnóstico consistió en 25 preguntas, las respuestas fueron analizadas y clasificadas objetivando-se su interpretación, lo que nos permite comprender los significados asignados por el estudiante a estos conceptos. Se desprende de la evaluación diagnóstica que la mayoría de los encuestados ha tenido dificultades para exponer los conceptos científicos sobre el Universo y la Tierra, para iniciar el 6 º grado. Sin embargo, se identificaron ideas relevantes y las representaciones que contribuyeron a la re-significación de los conceptos científicos propuestos para la enseñanza del tema en esta serie. Los resultados de la evaluación diagnóstica han servido como referencia para la organización del Programa, facilitando el proceso de aprendizaje, haciendo coincidir la secuencia didáctica a las características de los estudiantes y el contexto del aula. Se espera que el instrumento presentado en este documento también pueda ser utilizado por otros investigadores en investigaciones relacionadas con el tema.

    Some public-square games are presented in this paper, considered as didactic modules to help children imagine astronomical processes, based on the concept that learning in Astronomy should be developed to strengthen the relationship of our body with three-dimensional space and time, much in the same way we experience when observing the actual sky, holding a permanent "dialogue" between the actual world and what is to be learned. The games presented (merry-go-rounds and slides) were designed to work on the astronomical concepts related to the translation of the Earth around the Sun, the phases of the Moon and gravity, and on what is perceived by an observer about those phenomena. The description of each game, their physical and astronomical foundations, and a critical comment about their didactical importance are the key parts of the paper. Finally, a recommendation is given about the role teachers should play to be essential partners in the process of learning Astronomy by means of the interaction with these games. Se presentan en este trabajo algunos juegos de plaza, considerados como módulos didácticos para imaginar procesos astronómicos, a partir de la concepción de que el aprendizaje en Astronomía debe desarrollarse fortaleciendo la relación del propio cuerpo con el espacio tridimensional y con el tiempo, tal como se vive al observar el cielo, construyendo un "diálogo" entre el mundo real y los aprendizajes a construir. Los juegos presentados (calesitas y toboganes) fueron diseñados para trabajar sobre la traslación de la Tierra en torno al Sol, las fases de la Luna y la gravedad, y sobre lo que un observador percibe de los mismos. Se da la descripción de cada juego, se discuten sus fundamentos físicos y astronómicos, y se desarrolla una crítica didáctica de los mismos. Finalmente, se comenta el rol que deberían tener los docentes en el acompañamiento a los aprendices en el proceso de interacción con los juegos presentados.

Os jogos apresentados (carrosséis e tobogãs) foram desenhados para trabalhar sobre a translação da Terra em torno do Sol, as fases da Lua e a gravidade, e sobre o que um observador percebe dos mesmos. Dá-se a descrição de cada jogo, discutem-se seus fundamentos físicos e astronômicos, e desenvolve-se uma crítica didática dos mesmos.

    Rivera Pacheco, Andres

    El proposito de esta investigacion, un estudio cualitativo de caso, fue comparar y contrastar el curriculo vigente de la Escuela de Optometria de la UIAPR con las competencias y estandares requeridos por las agencias de acreditacion y de revalida. Con este proposito, decidimos realizar una revision y un analisis de documentos: el prontuario de cada uno de los cursos de los curriculos implantados en el 1993 y en el 2001; las competencias y estandares establecidos por las agencias de revalida y de acreditacion; y las estadisticas en las que se analiza el porcentaje de estudiantes que aprueban cada una de las partes de los examenes de revalida entre el 1998 al 2003. Se realizaron entrevistas dirigidas para dar apoyo y complementar la revision y el analisis de estos documentos. Los participantes de las entrevistas fueron tres estudiantes de la clase de optometria del 2004 (ultima clase del curriculo del 1993); tres estudiantes de la clase de optometria del 2005 (primera clase graduanda del curriculo vigente) y tres profesores y/o directores de los Departamentos de Ciencias Basicas, Ciencias Clinicas y Cuidado al Paciente. Esta investigacion se enmarco en el modelo de evaluacion curricular de discrepancia de Malcolm Provus y en el modelo de desarrollo basado en competencias. Uno de los hallazgos mas importantes del estudio es que los cambios que se implantaron al curriculo del 2001 no han logrado que los estudiantes mejoren su ejecucion en los examenes de revalida. Por otro lado, se encontro que el curriculo vigente atiende completamente los estandares de la practica de Optometria, pero no las competencias. Esta informacion fue validada mediante el uso de una tabla de cotejo para el analisis de los cursos y de la informacion obtenida de las entrevistas. El estudio determina y concluye que existen discrepancias entre los prontuarios de los cursos del curriculo y las competencias requeridas por la agencia de revalida. Segundo, que el Departamento de Ciencias Basicas es el que presenta mas deficiencias en el desarrollo de las competencias. El investigador recomienda disenar e implantar un curriculo basado en competencias y proveer formacion en didactica y procesos de aprendizaje a los profesores.

    This paper presents one of the concepts of Astronomy and its consequent failure in teaching this topic in high school, even when the official documents point out the necessity of Astronomy teaching at this school level. Among the spontaneous conceptions in Astronomy that high school students carry with them, even after the end of the school, we emphasized in this research the Moon phases. The development of different strategies in relation to traditional methods, aimed to teaching-learning process on this topic was considered in this study. These strategies were devised based on the reference frame of the Meaningful Learning, as elaborated by Ausubel. The proposals presented here include the active participation of students in experimental activities and other didactic activities, for their continuous evaluation during the process. These activities finished with a Comics elaboration about the Moon phases. Therefore, the objective of this paper is to present a proposal for differentiated teaching activity about Moon phases supported by the theoretical principles of Meaningful Learning at Physics classes. Este texto foca um dos conteúdos de Astronomia e a consequente falha no ensino deste tema no ensino médio, apesar de os documentos oficiais apresentarem a necessidade de se trabalhar a Astronomia neste nível de ensino. Dentre as concepções alternativas em Astronomia que os alunos do ensino médio carregam consigo, mesmo após o término dos estudos, destacamos, nesta pesquisa, o fenômeno das fases da Lua. O desenvolvimento de estratégias diferenciadas em relação ao ensino tradicional, visando o processo de ensino-aprendizagem sobre este tema, foi contemplado neste trabalho como um dos resultados obtidos sob a luz dos referenciais da aprendizagem significativa, fundamentados em Ausubel. Segundo a proposta aqui apresentada, a participação ativa dos alunos na execução de uma atividade experimental e outras atividades didáticas, que visam sua contínua avaliação durante o processo, culmina com a elaboração de uma história em quadrinhos envolvendo as fases da Lua. Portanto, o objetivo deste trabalho é apresentar uma proposta de atividade didática diferenciada sustentada pelos princípios teóricos da aprendizagem significativa aplicada ao ensino das fases da Lua durante as aulas de Física no ensino médio. En este trabajo se presenta uno de los contenidos de la Astronomía y el evidente fracaso en la enseñanza del tema en la escuela secundaria, a pesar del hecho que los documentos oficiales apuntan para la necesidad de trabajar contenidos de Astronomía en este nivel. Entre los conceptos alternativos en Astronomía que los alumnos secundarios llevan consigo, aún después de terminados los estudios, destacamos aquí el fenómeno de las fases de la Luna. El desarrollo de diferentes estrategias en relación con los métodos tradicionales, dirigidas al proceso de enseñanza-aprendizaje en este tema fue considerado en este trabajo como uno de los resultados obtenidos a la luz de los referenciales del aprendizaje significativo, tal como fueron fundamentados por Ausubel. Según la propuesta que aquí se presenta, la participación activa de los estudiantes en la ejecución de una actividad experimental y otras actividades educativas destinadas a la evaluación continua durante el proceso culminó en la elaboración de una historieta respecto de las fases de la Luna. Por lo tanto, el objetivo de este trabajo es presentar una propuesta de actividad de enseñanza diferenciada con el apoyo de los principios teóricos del aprendizaje significativo aplicado a la enseñanza de las fases de la luna durante las clases de física del ciclo secundario.

    There are many ways to construct the field R of real numbers. The most important and famous of these employ Cauchy sequences (Cantor) or cuts (Dedekind) in the field Q of rational numbers. These constructions sometimes overlook important details and often are complicated and cumbersome. In this note, the authors propose an essential, clear and rigorous construction of R from the stucture Q+ of positive rational numbers by the key notion of initial segment.

    The statistical analysis of a sample of data includes the collection; the analysis and the interpretation of them. For example; the construction of histograms has proven to be a powerful tool in statistics; from which it is possible to obtain an overview of the distribution of the data sample considered. In some circumstances; however; the results often depend on the way they are constructed (e.g. size of the bins used; etc.) leading to a variety of possible interpretations. Specifically; this paper presents a statistical method that allows to unravel the intrinsic distribution of a n-dimensional data distribution from "adaptive bins" and the consideration of the errors of the data used.

    This is a report of an activity of introduction to the study of Astronomy developed with a group of future Physics teachers at a Brazilian public university. Such activity had the goal of giving privileged emphasis to notions of spatiality, alternative conceptions of the participants and the process of interaction among peers, and consisted of the representation, in a three dimensional space, of the models of the universe that the participants had. The results, which were categorized as miscellaneous, geocentric, heliocentric and acentric models of the universe, were qualitatively analyzed. Analyses of the activity in the perspective of the participants are indicated and additional considerations are made regarding its use as a resource for teaching Astronomy and for teacher training.

    Research developed with 95 students of the 6th year of elementary education in a public school of Uberlândia, Minas Gerais. It was a continuous work from February to December 2013, which led the students to participate in activities of observation of the environment, specifically the sky, analyzing the changes occurred. We focused on the study of variations in temperature, rainfall, day length, variations in the size of the shadows and changes in the aspect of the Moon. Our focus of analysis targeted the discussion of the knowledge that these students had about the topics indicated and as they entered the stage during the implementation of the proposal. The results showed a limited perception that students have of their environment, however, lately expanded due to the undertaken activities, especially in relation to the Moon. Working with systematic measure procedures reveals the careful handling of data so that they become understandable to students, and working with the shadows points towards the students first understand how shadows are formed, and then apply this knowledge to Astronomy. Finally, we conclude that the lived process consisted of an initial step of a work that should be encouraged for the subsequent years of training of these students. Proyecto de investigación desarrollado con 95 alumnos del sexto año de primaria en una escuela pública de Uberlândia, Minas Gerais. Fue un trabajo continuo, de febrero a diciembre de 2013, que llevó a los estudiantes a participar en actividades de observación de su entorno, entre ellas, el cielo, analizando los cambios ocurridos. Nos centramos en el estudio de las variaciones en la temperatura, las precipitaciones, la duración del día, las variaciones en el tamaño de las sombras y los cambios en los aspectos de la Luna. Nuestro foco de análisis se centró en discutir el conocimiento que estos estudiantes tenían sobre los temas indicados al inicio y término de la propuesta. Los resultados mostraron una percepción limitada que los estudiantes tienen de su alrededor la cual, sin embargo, se expandió debido a las actividades llevadas a cabo, sobre todo en relación con la Luna. Trabajar con medidas sistemáticas revela el manejo cuidadoso de los datos para que sean comprensibles para los estudiantes, así como el trabajo con las sombras para que comprendan primero como se forman estas para después trabajarlas en Astronomía. Por último, llegamos a la conclusión de que el proceso desarrollado consistió en una etapa inicial de una obra que debe ser profundizado en los años posteriores de la formación de estos estudiantes. Projeto de pesquisa desenvolvido com 95 alunos do 6º ano do Ensino Fundamental de uma escola pública estadual de Uberlândia, Minas Gerais.

Focamos no estudo das variações de temperaturas, chuvas, duração do dia, variações do tamanho das sombras e mudanças nos aspectos da Lua. Nosso foco de análise centrou-se em discutir os conhecimentos que os referidos alunos tinham acerca dos temas indicados no início e ao término da implementação da proposta. Os resultados mostraram a percepção limitada que os estudantes possuem de seu entorno, todavia, ampliada em função das atividades desenvolvidas, principalmente no que se refere à Lua. O trabalho com medidas sistemáticas revela o cuidado no tratamento dos dados para que eles se tornem compreensíveis aos alunos, assim como o trabalho com as sombras sinaliza para que os alunos primeiramente compreendam como as sombras são formadas para depois trabalhar isso em Astronomia. Por fim, concluímos que o processo vivido constituiu-se em uma etapa inicial de um trabalho que deve ser estimulado para os anos subsequentes da formação desses alunos.

    We present the results obtained in a research on the comprehension of basic astronomical concepts, in which 561 students from fifth grade middle school to third grade high school of a public school of the city of Foz do Iguaçu (Brazil) took part. A test with 20 multiple-choice questions was applied to indentify the most common conceptions expressed by the students. This test was elaborated based on the literature about misconceptions and covered the following topics: the day-night cycle; the time zones; the seasons of the year; the phases of the Moon; the movement of the Moon; the apparent movement of the Sun in the celestial sphere; the eclipses; the dimensions and distances in the Universe; the brightness of the stars and its observation from Earth. Though a small progress was verified in the proportion of scientifically acceptable answers when comparing the eighth grade of middle school to the fifth, and the third grade of high school to the first, there was an overall predominance of alternative conceptions regarding most of the explored subjects, which persisted up to the last year of secondary school. The comparison to data found in this research made in other socio-cultural contexts revealed, in many aspects, similar notions and difficulties revealed by the students. Se presentan los resultados de una investigación sobre la comprensión de conceptos astronómicos básicos, en la cual participaron 561 estudiantes que cursaban entre el quinto grado de la enseñanza primaria y el tercer año de la enseñanza secundaria de una escuela pública de la ciudad de Foz do Iguaçu (Brasil). Se utilizó un test de 20 preguntas de opción múltiple para identificar las concepciones más comunes expresadas por los estudiantes. Este instrumento de recolección de datos se desarrolló en base a la literatura sobre las concepciones alternativas y trató los siguientes temas: el ciclo día-noche, los husos horarios, las estaciones del año, las fases de la Luna, el movimiento de la Luna, el movimiento aparente del Sol sobre la esfera celeste, los eclipses, las dimensiones y las distancias en el Universo, el brillo de las estrellas y su observación de la Tierra. Si bien ha habido un pequeño progreso en la proporción de respuestas aceptables científicamente cuando se cotejó el octavo grado de la enseñanza primaria con el quinto, y el último año de la enseñanza secundaria con el primero, se observó un predominio de las concepciones alternativas en relación a la mayoría de los temas explorados, que continuó hasta los últimos años de la educación básica. Una comparación con los datos encontrados en investigaciones realizadas en otros contextos socioculturales revelaron, en muchos aspectos, conceptos y dificultades similares expresadas por los estudiantes.

  6. Confieso que Divulgo. Reflexiones y Experiencias de una Astrofísica

    NASA Astrophysics Data System (ADS)

    Rodríguez Hidalgo, I.

    Este artículo presenta algunas reflexiones en torno a la popularización de la Ciencia, desarrolladas a lo largo de mi trayectoria profesional, un camino inacabado desde la intuición al oficio. Tras revisar las señas de identidad de la divulgación científica, se exponen ideas, experiencias y recursos, cribados por la práctica y su posterior análisis crítico. Se destacan las actividades relacionadas con la Astronomía, que se cuentan entre las más espectaculares y gratificantes. Confessions of a popularizer: This paper presents some author's thoughts about scientific outreach, developed along her professional path, an unfinished way from intuition to trade. First, identity signs of outreach are revised; then, ideas, experiences and resources, sifted by practice and further critical analysis, are reviewed. Activities related to Astronomy, being one of the most spectacular and rewarding, are remarked 1

    Prominence eruptions are one of the most spectacular manifestations of solar activity; in addition to flares and coronal mass ejections. Both filaments and prominences are chromospheric material suspended in the corona by the magnetic field. Hence their importance as tracers of field ejections. Some parts of their magnetic structure are not well understood; especially with regard to the loss of stability. On 06 December 2010 the H-Alpha Telescope for Argentina (HASTA) observed a prominence in the eastern solar limb including when part of it was ejected. In this paper the evolution of the filament is analyzed; its structure before and after the eruption; determining parameters that characterize it from HASTA data. FULL TEXT IN SPANISH

  14. Ionización en una atmósfera de carbono deficiente en hidrógeno

    NASA Astrophysics Data System (ADS)

    Milone, L. A.; Merlo, D. C.

    Assuming that LTE prevails, the ionization stage was analyzed in the atmosphere of a hydrogen defficient carbon (HdC) star: Y = 0.928, Zc = 0.056, X = 7 × 10-5, and remaining elements in approximately solar abundance (Z = 0.072). It is shown that in the shallower atmospheric layers, electron density in HdC is similar to that found in normal stars (as a consequence of assuming a quite similar metal abundance); in intermediate layers, C is the principal electron-donor, resembling H in normal composition stars, but similarity is not complete, as C is not so abundant in these stars as H is in normal stars (0.70 <= X <= 0.75). In deeper layers, He is the principal electron contributor. These facts, as well as the chemical composition, bring some consequences on the absorption in the stellar atmosphere; in solar composition stars, population II and HdC stars of medium temperature (5000 <= T <= 8000 K), the importance of different absorbers was analyzed. It was found that in the visual region, the absorption in a HdC star atmosphere is smaller than in a normal star. This paper will be published in full elsewhere and further details will be given there.

    The astronomy education community has tacitly assumed that learning astronomy is a conceptual domain resting upon spatial thinking skills. As a first step to formally identify an empirical relationship, undergraduate students in a non-major introductory astronomy survey class at a mediumsized, Ph.D. granting, mid-western US university were given pre- and post-astronomy conceptual diagnostics and spatial reasoning diagnostics, Instruments used were the "Test Of Astronomy Standards" and "What Do You Know?" Using only fully matched data for analysis, our sample consisted of 86 undergraduate non-science majors. Students' normalized gains for astronomy surveys were low at .26 and .13 respectively. Students' spatial thinking was measured using an instrument designed specifically for this study. Correlations between the astronomy instruments' pre- to post-course gain scores and the spatial assessment instrument show moderate to strong relationships suggesting the relationship between spatial reasoning and astronomy ability can explain about 25% of the variation in student achievement. La comunidad de educación en astronomía ha supuesto de forma tácita que el aprendizaje de la astronomía consiste en un dominio conceptual fundamentado en el razonamiento espacial. Como un primer paso para identificar formalmente una relación empírica entre estas dos cosas, utilizamos como muestra los estudantes de graduación de carreras no científicas de un curso experimental en una universidad norteamericana del medioeste de porte mediano con programa de Doctorado em curso, en el cual estos estudiantes se sometieron a un diagnóstico de razonamiento espacial y conceptos astronómicos antes e después del mismo. Las herramientas utilizadas fueron el Test Of Astronomy Standards (TOAST) y el cuestionario What do you know? Utilizando solo los datos completamente consistentes para este análisis, nuestra muestra consistió en 86 estudantes de graduación. Las mejoras, depués de normalizadas, en el desempeño de los estudiantes en estos dos asuntos foram pequenas, 0.26 e 0.13 respectivamente. El razonamiento espacial de los estudiantes fue medido utilizando un instrumento específico desarrollado para este trabaljo. Las correlaciones entre los resultados de los tests astronómicos y este instrumento específico, antes y después del curso mostraron una relación entre moderada y fuerte, sugiriendo que la relación entre el razonamiento espacial y el conocimiento astronómico puede explicar hasta un 25% de la variación em el desempeño de los estudiantes.

    The aqueous extracts of 64 plant species, listed as animal- or insect-bite antidotes in old Thai drug recipes were screened for their activity against fibroblast cell lysis after Heterometrus laoticus scorpion venom treatment. The venom was preincubated with plant extract for 30 min and furthered treated to confluent fibroblast cells for 30 min. More than 40% efficiency (test/control) was obtained from cell treatment with venom preincubated with extracts of Andrographis paniculata Nees (Acanthaceae), Barringtonia acutangula (L.) Gaertn. (Lecythidaceae), Calamus sp. (Palmae), Clinacanthus nutans Lindau (Acanthaceae), Euphorbia neriifolia L. (Euphorbiaceae), Ipomoea aquatica Forssk (Convolvulaceae), Mesua ferrea L. (Guttiferae), Passiflora laurifolia L. (Passifloraceae), Plectranthus amboinicus (Lour.) Spreng. (Labiatae), Ricinus communis L. (Euphorbiaceae), Rumex sp. (Polygonaceae) and Sapindus rarak DC. (Sapindaceae), indicating that they had a tendency to be scorpion venom antidotes. However, only Andrographis paniculata and Barringtonia acutangula extracts provided around 50% viable cells from extract treatments without venom preincubation. These two plant extracts are expected to be scorpion venom antidotes with low cytotoxicity. PMID:16169172

    The purpose of this research was to capture the memories, practices, thoughts and philosophies of education that four experienced Science teachers have accumulated through the years. The life story qualitative research design was used in order to collect more meaningful information from the participants amenable to in depth analysis and interpretation. The life stories interviews were conducted using an interview protocol especially designed for the study. The interviews were recorded and transcribed. The questions that guided this research are: 1. What are the meanings that science teachers give to their educational practices? 2. How did the life experiences of the participants contribute to their success as science teachers? 3. How did the participants' educational practices change and evolve over time? 4. What does teaching science mean in the life of the participants? 5. Which reflections arise from the work of the participants that impact the teaching of science? 6. What are the participants' conceptions about teachers' professional development? 7. What are the participants' contributions to the field of scientific education? Wolcott's (1994) DAI analytical model was used for the analysis of the information and the narratives were written following the three dimensions of the model: description, analysis and interpretation. According to the life stories of the participants, being a teacher requires more than teaching the content. To be a successful and an exemplary science teacher, they have to live the teaching vocation, with dedication, passion, commitment and love for teaching, for students and science; teachers have to give their best for the students, even if it means making personal sacrifices; they should keep updated in knowledge (content) and in educational innovations (strategies); emphasizing both the theoretical and the practical aspects in the field of science, and being an inspirational guide for students.

    RIASSUNTO. Scopo. I pazienti con un disturbo mentale cronico spesso possono soffrire di disfunzioni sessuali. La funzione sessuale dei nuovi pazienti con primo esordio psicotico è stata poco studiata. L'obiettivo di questo studio è quello di indagare le differenze di genere nella funzione sessuale in persone con primo episodio psicotico. Metodi. Hanno partecipato alla ricerca un gruppo di 40 uomini e 37 donne con primo episodio psicotico, a cui è stato somministrato un protocollo psichiatrico composto dalla PANSS, dall'UKU, e dalla SCID-DSM-IV per effettuare la diagnosi. Risultati. Nel gruppo maschile, il 42,5% dei pazienti aveva disfunzioni sessuali, mentre la percentuale nelle gruppo femminile è stata del 37,8%. Non c'è stata nessuna correlazione tra disfunzioni sessuali e psicopatologia negli uomini. Invece, nelle donne la psicopatologia generale e i sintomi positivi sono risultati associati all'alterazione della lubrificazione vaginale (r=0,547; p=0,003) and (r=0,485; p=0,011), sebbene anche l'alterazione nella risposta orgasmica è risultata correlare con la psicopatologia generale (r=0,500; p=0,013). Inoltre, è stata trovata un'associazione tra l'alterazione della lubrificazione vaginale con la depressione (r=0,627; p<0,0001) e il disturbo della volontà (r=0,600; p<0,001). Discussione e conclusioni. Questi dati suggeriscono che l'associazione tra disfunzioni sessuali e psicopatologia ha riguardato esclusivamente le donne. Pertanto, durante la presa in carico dei pazienti è fondamentale considerare l'associazione genere-specifica tra psicopatologia e problemi sessuali. PMID:26489073

Previously, only three chloroplast genomes (Oltmannsiellopsis viridis, Pseudendoclonium akinetum, and Bryopsis hypnoides) and two mitochondrial genomes (O. viridis and P. akinetum) from the class Ulvophyceae have been published. Here, we present the first chloroplast and mitochondrial genomes from the ecologically and economically important marine, green algal genus Ulva. The chloroplast genome of Ulva sp. was 99,983 bp in a circular-mapping molecule that lacked inverted repeats, and thus far, was the smallest ulvophycean plastid genome. This cpDNA was a highly compact, AT-rich genome that contained a total of 102 identified genes (71 protein-coding genes, 28 tRNA genes, and three ribosomal RNA genes). Additionally, five introns were annotated in four genes: atpA (1), petB (1), psbB (2), and rrl (1). The circular-mapping mitochondrial genome of Ulva sp. was 73,493 bp and follows the expanded pattern also seen in other ulvophyceans and trebouxiophyceans. The Ulva sp. mtDNA contained 29 protein-coding genes, 25 tRNA genes, and two rRNA genes for a total of 56 identifiable genes. Ten introns were annotated in this mtDNA: cox1 (4), atp1 (1), nad3 (1), nad5 (1), and rrs (3). Double-cut-and-join (DCJ) values showed that organellar genomes across Chlorophyta are highly rearranged, in contrast to the highly conserved organellar genomes of the red algae (Rhodophyta). A phylogenomic investigation of 51 plastid protein-coding genes showed that Ulvophyceae is not monophyletic, and also placed Oltmannsiellopsis (Oltmannsiellopsidales) and Tetraselmis (Chlorodendrophyceae) closely to Ulva (Ulvales) and Pseudendoclonium (Ulothrichales).

    Optical aperture spectroscopy and CCD broad- and narrow-band images are presented for the barred Seyfert 1 galaxy: IRAS 22117-3903. IRAS data are also used to analyse this object. The CTIO broad band CCD imaging show interesting morphological features: a compact nucleus with a prominent bar; two bright spiral arms; and a partial/segmented inner ring. The narrow-band imaging show that the nuclear H+[NII] emission is concentrate mainly in the nucleus. We find optical spectral features characteristic of a Seyfert 1.5 nucleus; i.e.; showing hydrogen emission lines with broad and narrow components. We detected high excitation emission lines ([CaV]+[FeXIV]; [FeVII]). We study the stellar population in the nuclear region. We find that the stellar population that represent quite well the nuclear stellar population is an average of spiral galaxies dominated by the old population plus a contribution of young stars. Physical conditions are derived for the narrow emission line region; and we detected very high electron temperature (T=4400045000 K); untypical for the ordinary AGNs and probably associated to shocks in a starburst component. Finally; at the optical and IR wavelength; we find properties typical of an nucleus with compound nature; in good agreement with the AGN/QSOs evolutionary model of Lípari ; Terlevich (2006; ; 368; 1001).

    HIV preventive efforts with heterosexual couples are almost nonexistent. We designed a group intervention based on the Information-Motivation-Behavioral Skills model with the aim of increasing male condom use and promoting the practice of mutual masturbation as a safer sex alternative. We carried out a pilot study with four couples to evaluate the feasibility of the intervention and the aspects of content and format that needed to be modified. Findings reflect that participants were very satisfied with the intervention and they found it entertaining and innovative. They were very comfortable with its format, as well as with the activities. The findings confirm the feasibility of this intervention and the need to direct preventive efforts to this population. PMID:23847716

    2013-01-01

    Objective: To evaluate the nephroprotective effect of methanolic extract of Hygrophila spinosa (HSME) (Acanthaceae) in (CP)-induced acute renal failure in rats. Materials and Methods: HSME (250 mg/kg and 500 mg/kg body weight), were administered orally to male wistar albino rats.CP was used to induce acute renal failure. The parameters studied included blood urea and serum creatinine and malondialdehyde (MDA), reduced glutathione (GSH), catalase (CAT), superoxide dismutase (SOD) and GSH peroxidase activities. Histopathological examination was also carried out. Results: The results revealed that HSME pretreatment signiûcantly reduced blood urea and serum creatinine levels elevated by CP administration. Furthermore, HSME signiûcantly attenuated CP-induced increase in MDA and decrease in reduced GSH, and CAT and SOD and GSH peroxidase activities in renal cortical homogenates. Additionally, histopathological examination showed that HSME markedly ameliorated CP-induced renal tubular necrosis. Conclusion: The results indicate that the aerial parts of H. spinosa are endowed with nephroprotective activity. PMID:23833364

    Objective: Graptophyllum pictum (L.) Griff. (Family-Acanthaceae) occupies a key role in traditional system of medicine. Since an extensive literature survey did not provide any information about studies on its standardization. Therefore, we designed the current study to establish the quality control parameters of G. pictum aerial parts. Materials and Methods: The investigation included determination of various standardization parameters such as macroscopic and microscopic studies, physicochemical parameters as well as phytochemical analysis of the crude drug. Results: The microscopy study of aerial parts revealed that stem shows typical dicotyledonous characters with prismatic crystals of calcium oxalate in the cortical region and dorsiventral leaf. Physicochemical constants such as moisture content, ash values, fluorescence analysis, and extractive values were established. Preliminary phytochemical analysis confirmed the presence of alkaloids, flavonoids, saponins, tannins, etc. Conclusion: The present study suggests establishing the parameters for pharmacopoeial standardization of G. pictum.

    Aldose reductase is the first enzyme in the polyol pathway and catalyzes the reduction of glucose to sorbitol by coupling with the oxidation of NADPH to NADP(+) . This sorbitol accumulation leads to various diabetic complications, including neuropathy, nephropathy, cataracts, and retinopathy. In the present study, aldose reductase inhibitory (ARI) activity of the methanolic as well as standardized extracts of Andrographis paniculata (Burm. f.) Wall. ex Nees (Acanthaceae) and its chief constituent, andrographolide, were studied using in vitro and in vivo methods. In the in vitro method, rat lens as well as kidney homogenates were used for the preparation of enzyme, whereas the effect of these test samples on the galactitol level in the eye lens was studied in a galactosemic rat model in vivo. The results of the study revealed that both extracts of the plant and its major compound, andrographolide, possess ARI activity in vitro. They were also found to significantly decrease galactitol accumulation in vivo. PMID:22628202

    SciTech Connect

    Eppler, D.; Fakundiny, R.; Ritchie, A.

    1986-12-01

    Six geothermal spring sites were selected on the basis of preliminary investigations conducted in Honduras over the last decade and were evaluated in terms of their development potential. Of the six, the Platanares and San Ignacio sites have high base temperatures and high surface fluid discharge rates and appear to have the best potential for further development as sources of electrical power. A third site, Azacualpa, has a high enough base temperature and discharge rate to be considered as a back-up, but the logistical problems involved in geophysical surveys make it less attractive than the two primary sites. Of the remaining three sites, Pavana may be a source of direct-use heat for local agricultural processing. Sambo Creek and El Olivar have either severe logistical problems that would impede further investigation and development or base temperatures and flow rates that are too low to warrant detailed investigation at this time.

    We present a photometric study of the globular cluster system (GCS); associated to the lenticular galaxy NGC6861. It is based on GEMINI/GMOS images in the filters g'; r'; i' of three fields; one of them centered on the galaxy. Studying the colour-magnitude diagram of the system; we detect the presence of at least two populations of GCs (``blue'' and ``red'') and the presence of the phenomenon known as ``blue-tilt''. However; analyzing the colour distribution we infer the existence of a third population with intermediate colours which could be interpreted as evidence of a past interaction or fusion event.

    1964-01-01

    Pioneering scientific information in underdeveloped areas poses several problems, such as (1) lack of understanding on the part of key functionaries as to the why, what, and when of information services; (2) lack of trained personnel to assume the responsibility for such services; (3) lack of economic resources; and (4) lack of information pertaining to available bibliographical sources in the particular area or region. The Bibliographic and Documentation Service of the Institute of Nutrition of Central America and Panama (INCAP) provides, in addition to the customary services, technical assistance for the organization or reorganization of biomedical libraries and makes INCAP library materials available to member countries, either by loan or photocopy. Although the program was designed for the member countries, INCAP tries to make its services available to other Latin American nations, Africa, and Asia, where similar nutritional problems are being studied.

    This paper presents a first approach in order to design an optimal architecture to implement the Numerov method, which solves the time-independent Schroedinger equation (TISE) for one dimension. The design and simulation have been performed by using 64-bits floating-point megafunctions available in Quartus II (Version 9.0). The verification of these results was done by using Matlab. According to these results, it is possible to extend this design to parallel structures, which would be able to calculate several TISE solutions.

    There are currently a vivid debate in Spain on the time zone which should follow the country. In this context this paper analyses Time Use surveys in Spain, Italy and United Kingdom and compares data extracted from them. The paper focus on universal activities like: sleeping, eating, working and the location "at home". Data are analysed on the regional basis provided by the surveys. Regional distributions of first and last occurrences of the activities are described by median values. Median values are then compared to each other by considering longitude and latitude. Within the interval of half a time zone, data show a good agreement. Which is to say, Spanish time schedules are not really weird if geographical position is taken into account. That includes also latitude. It is shown that midlatitude regions may undergo earlier time tables in the morning. ---- En el contexto de la discusi\\'on actual que se vive en Espa\\~na sobre la pertinencia de sus horarios y sobre el huso horario que ha de regir en el pa\\'is...

    The dequeismo phenomenon is occurring more frequently in spoken Spanish in both Spain and in Latin America. Introduction of the preposition "de" before "que" in nominal complements exploits one recourse in Spanish, namely the deictic capacity of prepositional "de" as a marker or introducer of the speaker's expressions, opinions, or thoughts.

    Background Chilean women have one of the highest smoking prevalence in the world. Aim To estimate the main factors associated with smoking initiation and quitting among a cohort of adult women living in a low socioeconomic status area of Santiago, Chile. Material and methods A random population-based sample of 1,100 women, 18 years and older, were selected from a community located in the South East area of Santiago. Sociodemographic, as well as smoking, beliefs, behaviors, stages of change and nicotine addiction level were recorded during a personal interview. After an average follow-up period of 5.5 years, women were re-evaluated. Results Seventy-three percent of women completed the study. At baseline, 39% of women were smokers. At the end of the study, there was an absolute smoking rate reduction of 7.1% (p<0.001). The main variables associated with smoking initiation were younger age (Odds ratio (OR): 1.08, 95% confidence intervals (CI): 1.05–1.12), higher education level (OR: 1.2, 95% CI: 1.07–1.35), and having fewer children (OR: 1.3 95% CI: 1.01–1.66). Factors related with quitting were younger age of onset (OR: 1.06 95% CI: 1.02–1.1), higher level of nicotine dependence (OR: 4.22, 95% CI: 1.74–10.27), and higher perception of smoking addiction (OR: 4.34, 95% CI: 2–9.09). Stage of change was associated with smoking cessation but its effect was diluted after adjusting for the level of nicotine addiction. Conclusions Sociodemographic and family factors were the main variables related with initiation, whereas age of onset, belief of addiction, and nicotine dependence were the main factors related with cessation. Women with a high motivation for quitting should be evaluated for nicotine addiction level to define the best strategy for intervention (Rev Méd Chile 2009; 137: 1001–9). PMID:19915762

    Rhinacanthin C is a naphthoquinone ester with anti-inflammatory activity, found in Rhinacanthus nasutus (L) Kurz (Acanthaceae). We found that rhinacanthin C inhibited osteoclast differentiation stimulated by the receptor activator of nuclear factor-?B ligand (RANKL) in mouse bone marrow macrophage cultures, although the precise molecular mechanisms underlying this phenomenon are unclear. In this study, we investigated the inhibitory mechanisms of rhinacanthin C in osteoclastogenesis. Rhinacanthin C suppressed RANKL-induced nuclear factor of activated T cells c1 (NFATc1) expression. Phosphorylation of ERK, JNK, and NF-?B, but not p38, was inhibited by rhinacanthin C, which also inhibited RANKL-stimulated TRAF6-TAK1 complex formation. Thus, the anti-osteoclastogenic effect of rhinacanthin C is mediated by a cascade of inhibition of RANKL-induced TRAF6-TAK1 association followed by activation of MAPKs/NF-?B; this leads to suppression of c-Fos and NFATc1, which regulate transcription of genes associated with osteoclast differentiation. In vivo, rhinacanthin C also reduced RANKL-induced osteoclast formation and bone resorption in mouse calvaria. Rhinacanthin C also suppressed LPS-stimulated osteoclastogenesis and bone resorption in vitro and in vivo. Rhinacanthin C may provide a novel therapy for abnormal bone lysis that occurs during inflammatory bone resorption. PMID:26083531

    Acanthus mollis (Acanthaceae), Achillea ligustica, Artemisia arborescens and Inula viscosa (Asteraceae) are used in Southern Italy against psoriasis and other skin diseases that occur with an imbalanced production of eicosanoids. We here assessed their in vitro effects upon 5-, 12-, 15-LOX and COX-1 enzymes as well as NF?B activation in intact cells as their possible therapeutic targets. All methanol crude extracts inhibited both 5-LOX and COX-1 activities under 200?µg/mL, without significant effects on the 12-LOX pathway or any relevant in vitro free radical scavenging activity. NF?B activation was prevented by all extracts but A. mollis. Interestingly, A. ligustica, A. arborescens and A. mollis increased the biosynthesis of 15(S)-HETE, an anti-inflammatory eicosanoid. A. ligustica (IC50?=?49.5?µg/mL) was superior to Silybum marianum (IC50?=?147.8?µg/mL), which we used as antipsoriatic herbal medicine of reference. Its n-hexane, dichloromethane and ethyl acetate fractions had also inhibitory effects on the LTB4 biosynthesis (IC50s?=?9.6, 20.3 and 68?µg/mL, respectively) evidencing that the apolar extracts of A. ligustica are promising active herbal ingredients for future phytotherapeutical products targeting psoriasis. © 2014 The Authors.

    Andrographis paniculata (Burm.f.) wall.ex Nees (Acanthaceae) or Kalmegh is an important medicinal plant finding uses in many Ayurvedic formulations. Diterpenoid compounds andrographolides (APs) are the main bioactive phytochemicals present in leaves and herbage of A. paniculata. The efficiency of supercritical fluid extraction (SFE) using carbon dioxide was compared with the solid-liquid extraction techniques such as solvent extraction, ultrasound-assisted solvent extraction and microwave-assisted solvent extraction with methanol, water and methanol-water as solvents. Also a rapid and validated reverse-phase high-performance liquid chromatography-diode array detection method was developed for the simultaneous determination of the three biologically active compounds, AP, neoandrographolide and andrograpanin, in the extracts of A. paniculata. Under the best SFE conditions tested for diterpenoids, which involved extraction at 60°C and 100 bar, the extractive efficiencies were 132 and 22 µg/g for AP and neoandrographolide, respectively. The modifier percentage significantly affected the extraction efficiency. PMID:24170124

    Adhatoda vasica (L.) (Acanthaceae) is used in the indigenous system of medicine in India. The alkaloid Vasicine was isolated from ethanolic extract of the leaves of A. vasica using column chromatography. Vasicine acetate was obtained by acetylation of Vasicine. Vasicine acetate exhibited good zone of inhibition against bacteria: 10?mm against E. aerogenes, 10?mm against S. epidermidis, and 10?mm against P. aeruginosa. Vasicine acetate showed minimum inhibitory concentration values against bacteria: M. luteus (125??g/mL), E. aerogenes (125??g/mL), S. epidermidis (125??g/mL), and P. aeruginosa (125??g/mL). The radical scavenging activity of Vasicine acetate was the maximum at 1000??g/mL (66.15%). The compound showed prominent cytotoxic activity in vitro against A549 lung adenocarcinoma cancer cell line. Quantification of Vasicine and Vasicine acetate by HPLC-DAD analysis showed their contents to be 0.2293% and 0.0156%, respectively, on dry weight basis of the leaves. Vasicine acetate could be probed further in drug discovery programme. PMID:25632399

    The morphology and chemical profile of the capitate glandular trichomes (CGTs) of Paragutzlaffia henryi (Acanthaceae) were investigated. Four new labdane diterpenoids named paraguhenryisins A-D (1-4), together with the known physacoztomatin (5), were localized to the CGTs using laser microdissection coupled with cryogenic (1)H NMR and HPLC analyses and were traced and isolated from the CGT extract of inflorescences. Their structures were determined by spectroscopic methods and single-crystal X-ray diffraction. Bioassays indicated significant inhibitory effect for these diterpenoids on Arabidopsis thaliana seed germination and seedling root elongation. The most potent inhibitor, paraguhenryisin C (3), was interestingly detected in both the rhizosphere soil and water rinsed inflorescences extract of P. henryi but not the roots, with average contents in the rhizosphere soil relevant to its phytotoxic EC50 values. These results suggested that phytotoxic labdane diterpenoids in the CGTs might be released into the environment as a defensive measure for P. henryi against other competitive plants. PMID:26513276

    Clinacanthus nutans (family Acanthaceae) has been used for the treatment of inflammation and herpes viral infection. Currently, there has not been any report on the qualitative and quantitative determination of the chemical markers in the leaves of C. nutans. The C-glycosidic flavones such as shaftoside, isoorientin, orientin, isovitexin, and vitexin have been found to be major flavonoids in the leaves of this plant. Therefore, we had developed a two-step method using thin-layer chromatography (TLC) and high pressure liquid chromatography (HPLC) for the rapid identification and quantification of the flavones C-glycosides in C. nutans leaves. The TLC separation of the chemical markers was achieved on silica gel 60 plate using ethyl acetate?:?formic acid?:?acetic acid?:?water (100?:?11?:?11?:?27?v/v/v/v) as the mobile phase. HPLC method was optimized and validated for the quantification of shaftoside, orientin, isovitexin, and vitexin and was shown to be linear in concentration range tested (0.4–200??g/mL, r2 ? 0.996), precise (RSD ? 4.54%), and accurate (95–105%). The concentration of shaftoside, orientin, vitexin, and isovitexin in C. nutans leave samples was 2.55–17.43, 0.00–0.86, 0.00–2.01, and 0.00–0.91?mmol/g, respectively. PMID:25405231

    Justicia wynaadensis locally known as Moddu Soppu belongs to the family Acanthaceae. The aqueous bluish purple color extracted from the leaves and stems of Justicia is used in the preparation of a sweet dish by the natives of Kodagu district, Karanataka, India, exclusively during the monsoons. This traditional practice is believed to keep the people healthy throughout the year. Owing to its potential to be used as a natural colorant there is a strong need to develop efficient extraction method for maximum yield of colorant and preliminary scientific study of stability. Microscopy was carried out to find out the location of purple color in both leaves and stem and to study the anatomical details. An optimized microwave extraction method for extraction of colorant from Justicia has been developed. The microwave oven extraction yield of colorant is 9.41 % (±0.8598) under the optimized conditions of extraction time 30 min., extraction temperature 150 °C and ratio of liquid to solid 30 ml/g. The study demonstrated that the purple extract of the plant was stable against pH range 6.0-8.0, low temperature (4 °C), high temperature (?50 °C) and sensitive to light. Thus these observations recommend the use of J. wynaadensis extract as a food colorant in neutral or slightly alkaline products (bakery, milk, egg etc.) and could be the potential source for the food colorant market.

    Andrographis paniculata Wall (family Acanthaceae) is one of the most popular medicinal plants used traditionally for the treatment of array of diseases such as cancer, diabetes, high blood pressure, ulcer, leprosy, bronchitis, skin diseases, flatulence, colic, influenza, dysentery, dyspepsia and malaria for centuries in Asia, America and Africa continents. It possesses several photochemical constituents with unique and interesting biological properties. This review describes the past and present state of research on Andrographis paniculata with respect to the medicinal usage, phytochemistry, pharmacological activities, toxicity profile and therapeutic usage, in order to bridge the gap requiring future research opportunities. This review is based on literature study on scientific journals and books from library and electronic sources. Diterpenes, flavonoids, xanthones, noriridoides and other miscellaneous compounds have been isolated from the plant. Extract and pure compounds of the plant have been reported for their anti-microbial, cytotoxicity, anti-protozoan, anti-inflammatory, anti-oxidant, immunostimulant, anti-diabetic, anti-infective, anti-angiogenic, hepato-renal protective, sex hormone/sexual function modulation, liver enzymes modulation insecticidal and toxicity activities. The results of numerous toxicity evaluations of extracts and metabolites isolated from this plant did not show any significant acute toxicity in experimental animals. Detailed and more comprehensive toxicity profile on mammalian tissues and organs is needed in future studies.

    The purpose of this investigation was to determine the antioxidant potentials and anti-glucosidase activities of six tropical medicinal plants. The levels of phenolic constituents in these medicinal plants were also quantified and compared. Antioxidation potentials were determined colorimetrically for scavenging activities against DPPH and NO radicals. Metal chelating assay was based on the measurement of iron-ferrozine absorbance at 562 nm. Anti-diabetic potentials were measured by using ?-glucosidase as target enzyme. Medicinal plants' total phenolic, total flavonoid and hydroxycinnamic acid contents were determined using spectrophotometric methods, by comparison to standard plots prepared using gallic acid, quercetin and caffeic acid standards, respectively. Radical scavenging and metal chelating activities were detected in all medicinal plants, in concentration-dependent manners. Among the six plants tested, C. nutans, C. formosana and H. diffusa were found to possess ?-glucosidase inhibitory activities. Spectrophotometric analysis indicated that the total phenolic, total flavonoid and hydroxycinnamic acid contents ranged from 12.13-21.39 mg GAE per g of dry sample, 1.83-9.86 mg QE per g of dry sample, and 0.91-2.74 mg CAE per g of dry sample, respectively. Our results suggested that C. nutans and C. formosana could potentially be used for the isolation of potent antioxidants and anti-diabetic compounds. To the best of our knowledge, this study represents the first time that C. nutans (Acanthaceae family) was reported in literature with glucosidase inhibition activity. PMID:25587331

    Andrographis paniculata (AP) is a medicinal plant species introduced into Malaysia. To address the genetic structure and evolutionary connectedness of the Malaysian AP with the Indian AP, a DNA sequence analysis was conducted based on 24 microsatellite markers. Out of the 24 primer sets, seven novel microsatellite primers were designed and amplified intra-specifically according to the available Indian AP sequences at the National Centre for Biotechnology Information (NCBI), where 17 of them were amplified using the cross-species strategy by employing the primers belonging to Acanthus ilicifolius Linn (Acanthaceae) and Lumnitzera racemosa Wild (Combretaceae). The primers were then applied on the Malaysian AP accessions. Sixteen of the new microsatellite loci were amplified successfully. Analysis of these microsatellite sequences, revealed some significant differences between the Indian and Malaysian AP accessions in terms of the size and type of the repeat motifs. These findings depicted the cryptic feature of this species. Despite identifying several heterozygous alleles no polymorphism was observed in the detected loci of the selected accessions. This situation was in concordance with the presence of "fixed heterozygosity" phenomenon in the mentioned loci. Accordingly, this was fully consistent with the occurrence of the genetic bottleneck and founder effect within Malaysian AP population. Apart from the amplification of new microsatellites in this species, our observations could be in agreement with the risk of genetic depletion and consequently extinction of this precious herb in Malaysia. This issue should be taken into consideration in the future studies. PMID:23086278

    Elenine is the aglycone of elenoside, a cytotoxic arylnaphthalene lignan (NSC 644013-W/1) derived from Justicia hyssopifolia. (Family: Acanthaceae). Elenoside is a ?-D-glucoside, with a similar chemical structure to etoposide, exhibiting central depressant activity. In the present study, elenine was given to mice and rats at doses of 10, 20, and 40?mg/kg. Acute toxicity (24?h) and general behaviour in mice was studied as well as its effects on muscular relaxant activity, locomotor activity (Varimex test), and the open-field test and were compared with 10?mg/kg of chlorpromazine. Elenine produced a reduction in the permanence time in muscular relaxant activity (traction test). Spontaneous activity was lower in the Varimex test. The ambulation and rearing were lower compared with the control group, and an increase in boluses was observed in the open-field test. Thus, it can be concluded that elenine has central sedative effects at lower doses than those used with elenoside and has a possible application in conditions of anxiety. PMID:21716687

    Cancer patients seek alternative remedies such as traditional medicinal plants for safe and effective treatment and help overcome the side effects of conventional therapy. Current knowledge indicates that extracts of Strobilanthes crispus of the Acanthaceae family exhibit potent anticancer properties in vitro and are non-toxic in vivo. S. crispus was also reported to be protective against chemical hepatocarcinogenesis. We previously showed that a bioactive fraction of S. crispus leaves also synergized with tamoxifen to cause apoptosis of human breast cancer cell lines without damaging non-malignant epithelial cells. The present study aimed to evaluate the antitumor effect of S. crispus dichloromethane fraction (F3) using N-methyl-N-Nitrosourea (NMU)-induced rat mammary tumor model. Tumor regression was observed in 75% of the rats following 8-week oral administration of F3 with no secondary tumour formation and no signs of anemia or infection. However, no improvement in the liver and renal function profiles was observed. Major constituents of F3 were identified as lutein, 131-hydroxy-132-oxo-pheophytin a, campesterol, stigmasterol, ?-sitosterol, pheophytin a and 132-hydroxy-pheophytin a. These compounds however, may not significantly contribute to the antitumor effect of F3. PMID:26000968

    The floodplains of Tortuguero, in northeastern Costa Rica, stand as one of the richest plant-species regions in Central America. In this paper, we present the annotated check-list of vascular plants that are present within the rainforest of Tortuguero National Park (TNP), a 26 604h land that protects most of the biological diversity of these plains. Our list resulted from collections made in 2012, as well as the examination of material mantained at the Herbarium of the National Biodiversity Institute of Costa Rica, INBio (ATTA Database) and in the TROPICOS database. A total of 732 vascular plant species included in 413 genera are known to the Park. Two of these species have limited distributions and are endemic to Costa Rica: Pseuderanthemum pittieri (Acanthaceae) and Paullinia austin-smithii (Sapindaceae). Ninety species have known ethnobotanical uses. The high diversity in plant species reported here for the forest environments of Tortuguero contrasts with the low species diversity previously reported in the palm-swamps that characterize the riverine habitats within the Park.

    This paper is based on data recorded from various literatures pertaining to ethnophytomedicinal recipes used against diabetes in South East Asia (India, Pakistan and Srilanka). Traditional plant treatments have been used throughout the world for the therapy of diabetes mellitus. In total 419 useful phytorecipes of 270 plant species belonging to 74 Angiospermic families were collected. From the review it was revealed that plants showing hypoglycemic potential mainly belong to the families, Cucurbitaceae (16 spp.), Euphorbiaceae (15 spp.), Caesalpiniaceae and Papilionaceae (13 spp. each), Moraceae (11 spp.), Acanthaceae (10 spp.), Mimosaceae (09 spp.), Asteraceae, Malvaceae and Poaceae (08 spp. each), Hippocrateaceae, Rutaceae and Zingiberaceae (07 spp. each), Apocynaceae, Asclepiadaceae and Verbenaceae (06 spp. each), Apiaceae, Convolvulaceae, Lamiaceae, Myrtaceae, Solanaceae (05 spp.each). The most active plants are Syzigium cumini (14 recipes), Phyllanthus emblica (09 recipes), Centella asiatica and Momordica charantia (08 recipes each), Azadirachta indica (07 recipes), Aegle marmelos, Catharanthus roseus, Ficus benghalensis, Ficus racemosa, Gymnema sylvestre (06 recipes each), Allium cepa, A. sativum, Andrographis paniculata, Curcuma longa (05 recipes each), Citrullus colocynthis, Justicia adhatoda, Nelumbo nucifera, Tinospora cordifolia, Trigonella foenum-graecum, Ziziphus mauritiana and Wattakaka volubilis (4 recipes each). These traditional recipes include extracts, leaves, powders, flour, seeds, vegetables, fruits and herbal mixtures. Data inventory consists of botanical name, recipe, vernacular name, English name. Some of the plants of the above data with experimentally confirmed antidiabetic properties have also been recorded. More investigations must be carried out to evaluate the mechanism of action of diabetic medicinal plants. Toxicity of these plants should also be explained. Scientific validation of these recipes may help in discovering new drugs from these medicinal plants for diabetes. PMID:25176368

    Background Stress caused by free radicals accumulation result into many hazardous diseases. A number of investigations are focusing to find out the plant oriented natural antioxidant moieties. The basic aim of this research was to investigate the antioxidant potential, total Phenolic and flavonoids contents and photochemical screening of the crude methanol extract and its derived various fractions Dicliptera roxburghiana of Acanthaceae family. Methods Crude methanol extract of aerial parts of Dicliptera roxburghiana (DRME) was partitioned in to n-hexane (DRHF), chloroform (DRCF), ethyl acetate (DREF), n-butanol (DRBF) and the remaining soluble portion as residual aqueous fraction (DRAF). We evaluated the antioxidant activities of the extract and various fractions through different analytical methods such as DPPH, superoxide anion, ABTS, H2O2, hydroxyl radical and phosphomolybdate radical inhibition. In vitro lipid peroxidation and reducing power of the plant was also analyzed. Total flavonoid and phenolic contents of the extract and all fractions were also quantified. Plant was also subjected for preliminary phytochemical screening to confirm the presence or absence of various constituents in the plant. Results Phytochemical screening confirmed the presence of flavonoids, phenolics, tannins, alkaloids, saponins, terpenoids and coumarines. Quantitative analysis revealed the maximum amount of total phenolic and flavonoid contents in DRME while lowest in DRHF. Methanol extract, DREF, DRCF and DRBF exhibited promising antioxidant potential for DPPH, ABTS, H2O2, phosphomolybdate, superoxide anion and hydroxyl radical scavenging capabilities, while these were not appreciable for DRHF and DRAF. All fractions except DRHF and DRAF possess strong reducing power ability and showed appreciable lipid peroxidation inhibition. Conclusion These research investigations revealed that Dicliptera roxburghiana is a potent source of natural antioxidants. Hence the plant can be used for management of different stress and anxiety related ailments. PMID:23777321

    Acanthus ilicifolius (Acanthaceae), a mangrove medicinal plant, is widely used by the local inhabitants of the Sundarbans (India) to treat a variety of diseases. As a part of our continued search for novel bioactive products from mangrove medicinal plants, we were able to document the anti-inflammatory effects of this plant. In the present study, we have performed a detailed evaluation of the gastroprotective activity of the methanolic extract of Acanthus ilicifolius using different models of gastric ulceration. Unlike the conventional non-steroidal anti-inflammatory drugs, a methanolic extract of Acanthus ilicifolius leaves (MEAL) possessing significant anti-inflammatory properties, as revealed from our previous studies displayed in rats in dosages of 200 mg and 400 mg/kg BW after intraperitoneal administration, showed significant protective activity (anti-ulcer activity) against the gastric lesions induced by aspirin, indomethacin, stress, ethanol, and pylorus ligation. In pylorus-ligated rats, administration of Methanolic extract of Acanthus ilicifolius leaves (MEAL) significantly decreased gastric volume, acidity, and peptic activity. Moreover, pre-treatment with MEAL significantly restored the levels of reduced glutathione (GSH) and the antioxidant enzyme superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPX), along with significant inhibition of both lipid peroxidation and myeloperoxidase (MPO) activity in pylorus-ligated animals. Ulceration induced with ethanol was significantly inhibited with MEAL, and the extract also resulted in the reduction of both lipid peroxidation and myeloperoxidase activity. Furthermore, in this experimental model, administration of MEAL improved the activities of SOD, CAT, GSH, and GPX. A similar pattern of action was also noticed in cold-restraint stress-induced (CRS) ulceration, where MEAL pre-treatment inhibited CRS-induced ulceration, improved the status of antioxidant enzymes, and also reduced the level of lipid peroxides. These results suggest that extracts of the leaves of Acanthus ilicifolius may exhibit anti-ulcer activities additional to the anti-inflammatory properties. PMID:23008816

    Background & objectives: Mosquitoes transmit serious human health diseases, causing millions of deaths every year. Plants may be sources of alternative mosquito control agents. The present study was carried out to assess the role of larvicidal activities of the crude extracts of four plants viz. Alternanthera sessilis L. (Amaranthaceae), Trema orientalis L. (Cannabaceae), Gardenia carinata Smith. (Rubiaceae) and Ruellia tuberosa L. (Acanthaceae) against Culex quinquefasciatus Say in laboratory bioassay. Methods: Selective concentrations (0.5, 1 and 1.5%) of crude extract of all four plant leaves were tested against Ist to IVth instar larvae of Cx. quinquefasciatus. Log probit analysis (at 95% confidence level) revealed the LC50 values. Preliminary qualitative phytochemical analyses of crude extracts were also done. The lethal concentrations (%) of crude extracts at 24 h against IIIrd instar larvae were also studied on non-target organisms. Result: In a 72 h bioassay experiment with crude extract, the highest mortality was recorded in 1.5 per cent extract. A. sessilis showed the highest mortality (76.7 %) at 1.5 per cent crude extract against IInd instar larvae having LC50 value of 0.35 per cent, followed by R. tuberosa (LC50 =1.84%), G. carinata (LC50 = 2.11) and T. orientalis (LC50 = 2.95%). The regression equation showed a dose-dependent mortality, as the rate of mortality (Y) was positively correlated with the concentration (X). Phytochemical analysis of the crude extract showed the presence of many bioactive phytochemicals such as steroids, alkaloids, terpenes, saponins, etc. No changes in the swimming behaviour and survivality of non-target organism were noticed at the studied concentrations. Interpretation & conclusions: Crude extract of the four selected plants showed larvicidal activity against Cx. quinquefasciatus. The extracts at the studied concentrations did not produce any harmful effect on non-target organisms. PMID:25222784

    The concept of "Cosmography" is in disuse since the 80s of the last century, but the astronomical themes previously discussed in the school subjects of Geography and Cosmography remain in current textbooks. The use of term "Cosmography" was rescued in this research, and the study of its re-signification prompted the appearance of the term Geographic Cosmography. The Geographic Cosmography is a field of studies of the Geography, whose set of knowledge and skills is predominantly scholar. It studies the interface between terrestrial and celestial knowledge, and assigns a geographic significance to them. It examines human and natural relationships with Sidereal Space and its consequences for society and nature. O conceito de "Cosmografia" está em desuso desde os anos 80 do século XX, mas os temas astronômicos anteriormente abordados nas disciplinas escolares de Cosmografia e de Geografia permanecem nos atuais livros didáticos. O uso do termo "Cosmografia" foi resgatado nesta pesquisa e o estudo de sua ressignificação proporcionou o surgimento do termo Cosmografia Geográfica. A Cosmografia Geográfica é um campo de estudos da Geografia, cujo conjunto de conhecimentos e habilidades é predominantemente escolar. Estuda a interface entre os conhecimentos terrestres e os celestes e lhes atribui significância geográfica. Analisa as relações humanas e naturais com o Espaço Sideral e suas consequências para a sociedade e a natureza.

  18. Quantitative mapping of elemental distribution in leaves of the metallophytes Helichrysum candolleanum, Blepharis aspera, and Blepharis diversispina from Selkirk Cu-Ni mine, Botswana

    NASA Astrophysics Data System (ADS)

    Koosaletse-Mswela, Pulane; Przyby?owicz, Wojciech J.; Cloete, Karen J.; Barnabas, Alban D.; Torto, Nelson; Mesjasz-Przyby?owicz, Jolanta

    Multi-element profiling is essential in understanding the metal-tolerant behavior of metallophytes. Although previous reports using multi-elemental analyses show that the metallophytes Blepharis aspera, Blepharis diversispina (Acanthaceae) and Helichrysum candolleanum (Asteraceae) take up metals, no information exists on elemental spatial distribution and concentrations in specific tissues of these plants. The aim of this study therefore was to assess the spatial distribution and concentration of copper, nickel and other elements in leaf tissues of these plants using micro-PIXE. Whole plants were collected with soil in pots from an operational copper and nickel mine (i.e., a copper and nickel mineralized area), Selkirk, about 40 km north-east of Francistown, Botswana. On the same day the samples were transported by air to iThemba LABS in South Africa. Leaf specimens were cryofixed in liquid propane cooled by LN2. Parallel samples were embedded in resin for anatomical studies to facilitate interpretation of elemental maps. The distribution and concentration of copper, nickel, and other elements in leaf tissues were determined using micro-PIXE and proton backscattering spectrometry. Data evaluation was performed using GeoPIXE II software. Micro-PIXE showed that H. candolleanum had the highest whole leaf content of copper (70 ± 3 ?g g-1 DW) and nickel (168 ± 5 ?g g-1 DW), followed by B. aspera (Cu: 25 ± 1 ?g g-1 DW; Ni: 166 ± 4 ?g g-1 DW) and B. diversispina (Cu: 3 ± 1 ?g g-1 DW; Ni, below detection limit). For specific leaf tissues, the highest levels of copper were found in the vascular bundle for H. candolleanum (167 ± 7 ?g g-1 DW) and the lower epidermis for B. aspera (70 ± 9 ?g g-1 DW). The highest levels of nickel were present in the vascular bundle of B. aspera (479 ± 10 ?g g-1 DW) and H. candolleanum (90 ± 5 ?g g-1 DW). Elemental maps showed a similar distribution pattern for copper and nickel in B. aspera and B diversispina, with these elements concentrated in the upper and lower epidermal regions. However, for H. candolleanum, both copper and nickel were concentrated in the mesophyll. The difference in concentration and accumulation patterns between B. aspera, B. diversispina and H. candolleanum suggests that the metal-tolerant adaptation of these metallophytes may differ.

    Oliveira Bernardes, Adriana; Ramos dos Santos, Arleidimar

    2008-12-01

    Volunteer advisors at Itaocara Astronomy Club Marcos Pontes(CAIMP), in their majority high school students, introduced students at Teotônio Brandão Vilela Elementary School to basic concepts in Astronomy, Physics, and Mythology. Computer Science, Arts, puppetry, and educational videos were used to stimulate students to share their feelings and test their knowledge of the concepts presented. The work done by the volunteers helped boost the student's self-esteem and improved their oral skills by applying their knowledge of Physics and Astronomy in Lab experiments. The main goals of the CAIMP are the possibility of including astronomy in Elementary school curricula and developing an interdisciplinary work involving Astronomy, Arts, and Mythology. Through tests and reports, the students who participated in the Brazilian Astronomy Olympics, showed an increase in their knowldge of the sujects presented during the volunteer work. Durante el curso de un trabajo voluntario con estudiantes de nivel primario (1 º a 4 º grado), los guías de Astronomía miembros del CAIMP (Club de Astronomía de Itaocara "Marcos Puentes"), en su mayoría estudiantes secundarios, desarrollaron un trabajo de introducción a las Ciencias y Astronomía con alumnos del colegio estatal Teotônio Vilela Brandão. A través de talleres de informática, artes, videos educativos y teatro de títeres, los estudiantes pudieron expresar sus conocimientos y emociones frente a las leyendas mitológicas con las que se inició el trabajo de introducción. La labor desarrollada por los guías con los alumnos promovió la integración entre las aulas del colegio haciéndolos participar en actividades con el fin de estimular su expresión verbal y aumentar su autoestima. Trabajando diversas formas de expresión, los alumnos pudieron realizar experimentos y conocer algunos conceptos de Física y Astronomía al mismo tiempo que adquirían autonomía para la libre expresión de sus sentimientos y de los conocimientos recibidos. El trabajo en sí ha mostrado además de la posibilidad de la inclusión de la Astronomía en la Educación Primaria, la posibilidad de un trabajo interdisciplinario en los niveles iniciales incluyendo Astronomía, Arte y Mitología. Los resultados presentados por los estudiantes en las Olimpiadas promovidas en la escuela y por la OBA (Olimpiada Brasilera de Astronomía) permitieron verificar un creciente aprendizaje y estimulo hacia las materias científicas, comprobados por la apropiada expresión de los conceptos adquiridos de astronomía y presentados en evaluaciones o en informes obtenidos de ellos mismos, sus familias y profesores. Desenvolvendo um trabalho voluntário junto aos alunos do ensino fundamental no 1º ciclo (1ª a 4ª série), os monitores de Astronomia membros do CAIMP (Clube de Astronomia de Itaocara Marcos Pontes), que eram em sua maioria alunos do ensino médio, desenvolveram um trabalho de aproximação entre os alunos do Colégio Estadual Teotônio Brandão Vilela e os temas envolvendo Ciências e Astronomia. Através de oficinas de informática, artes, vídeos educativos e teatros de fantoches, os alunos puderam expressar seus conhecimentos e emoções diante das lendas mitológicas com as quais começaram a ter contato. O trabalho desenvolvido pelos monitores junto aos alunos proporcionou a integração entre as turmas do colégio e os levou a participação em atividades de maneira a estimular sua oralidade e aumentar sua auto-estima. Trabalhando várias formas de expressões, os alunos puderam realizar seus experimentos e conhecer alguns conceitos de Física e Astronomia, enquanto adquiriam autonomia para se expressarem de acordo com seus sentimentos e conhecimentos adquiridos. O trabalho em si mostrou além da possibilidade de inserção de Astronomia no Ensino Fundamental, a possibilidade de realização de um trabalho interdisciplinar nas séries iniciais envolvendo Astronomia, Arte e Mitologia. Os resultados apresentados pelos alunos nas Olimpíadas promovidas na escola e pela OBA (Olimpíada Brasileir

    Impaired stress-induced pressure natriuresis, i.e., an inadequate increase in urinary sodium excretion (UNaV) in response to a stress-induced blood pressure increase, may lead to the premature development of essential hypertension. To assess the heritability of baseline UNaV, stress UNaV, and the UNaV response to stress (?UNaV = stress UNaV – baseline UNaV), we studied 396 African American (AA) and 494 European American (EA) twins, including monozygotic and dizygotic of same- as well as opposite-sex (mean age: 17.6 ± 3.3; range: 11.9–30.0). Bivariate genetic model fitting was performed to examine the extent to which genetic and environmental factors are common or specific to baseline and stress UNaV. Heritability estimates for ?UNaV can be derived from these bivariate models. All bivariate analyses were performed separately in EAs and AAs, because univariate models for baseline UNaV showed significant ethnic differences in heritability estimates. Best fitting models showed that the heritability of stress UNaV was 0.42 in EAs and 0.58 in AAs. Only 15% and 11% of the total variance could be attributed to genetic factors common to baseline and stress UNaV in EAs and AAs, respectively. After removal of all shared influences with baseline UNaV, heritabilities for stress UNaV were 0.32 in EAs and 0.57 in AAs. Heritability estimates for ?UNaV were 0.36 in EAs and 0.39 in AAs. In summary, this study establishes ?UNaV and stress UNaV as heritable phenotypes that may be used to study the genetic etiology of early hypertension development. PMID:19104006

  7. Late Pleistocene- Holocene Dynamics of a Central Himalayan Glacier using multi-proxy data

    NASA Astrophysics Data System (ADS)

    Bali, R.

    2013-12-01

    Palaeoglacial reconstruction based on geomorphological mapping in the Pindari glacier valley of Central Himalaya has revealed the presence of five glacial stages with decreasing magnitude. The oldest and most extensive stage-I glaciation deposited sediments upto an altitude of 2200 masl. The stage-II glaciations luminescence dated to 25 × 2 ka, has deposits at 3200 masl. Remnants morainic ridges found around 3850 masl and dated to 6 × 1 ka represent the Stage-III glaciations. The sharp crested crescentic moraine extending from around 3650 masl to 3900 masl is attributed to stage-IV glaciation and is dated to 3 × 1 ka. Four sharp crested unconsolidated moraines on the valley floor represent the stage-V. A 435 cm deep Glacio-lacustrine sedimentary deposit from Jeha Gaer, in the vicinity of Pindari Glacier has been analysed using multiproxy data. The palynological and mineral magnetic data aided with 14C and Optically Stimulated Luminescence (OSL) dates suggests that the region has witnessed variability in climatic conditions. The study suggests that this region has experienced at least six major natural climatic changes during the last 7,000 years. The climate for the region has been worked out to be cold and dry during 7 ka BP followed by five different vegetational shifts. The vegetation complex as marked by high conifers associated with broad leaved as well as herbaceous taxa and high magnetic susceptibility suggests the amelioration of climate during 7 ka to 4.9 ka BP. Thereafter, during 4.9 ka to 1.75 ka BP, the climate once again shows cold and drier condition as evidenced by acceleration of alpine herbaceous taxa with gradual decrement of conifers and broad leaved taxa. However, during 1.75 ka to 0.9 ka BP, the climate seems to have become relatively warm and moist (~Medieval Warm Period) as evidenced by the presence of both conifers and broad leaved taxa along with fair amount of Rhododendron. During 0.9 ka to 0.2 ka BP, a drastic climatic change has been witnessed (~Little Ice Age) as evidenced by the relative decline in conifers and broad leaved taxa except Quercus and Rhododendron. The sediments of this zone also show lower values of the magnetic susceptibility. Since the last 300 yr BP onwards, the vegetation complex including conifers, broad leaved taxa along with herbaceous elements along with high magnetic susceptibility indicates warm and moist climatic regime. The presence of cereals (>60?m) along with culture pollen like Tubulifloreae, Acanthaceae, Caryophyllaceae and Polygonaceae also support the high pastoral activity during this phase. Further, the steady presence of both monolete and trilete fern spores suggest an overall warm and moist climatic condition as prevailing presently in and around the study area. It is hereby emphasised that both the palynological and environmental magnetic climatic proxies suggest that in the (central) Himalayan region, the present phase of warming started almost 300 years BP and seems to have been continuing since then. The warming of climate thus seems to have been initiated prior to the beginning of the anthropogenic activity.

  6. Allele-selective inhibition of expression of huntingtin and ataxin-3 by RNA duplexes containing unlocked nucleic acid substitutions.

    Unlocked nucleic acid (UNA) is an acyclic analogue of RNA that can be introduced into RNA or DNA oligonucleotides. The increased flexibility conferred by the acyclic structure fundamentally affects the strength of base pairing, creating opportunities for improved applications and new insights into molecular recognition. Here we test how UNA substitutions affect allele-selective inhibition of expression of trinucleotide repeat genes Huntingtin (HTT) and Ataxin-3 (ATX-3). We find that the either the combination of mismatched bases and UNA substitutions or UNA substitutions alone can improve potency and selectivity. Inhibition is potent, and selectivities of >40-fold for inhibiting mutant versus wild-type expression can be achieved. Surprisingly, even though UNA preserves the potential for complete base pairing, the introduction of UNA substitutions at central positions within fully complementary duplexes leads to >19-fold selectivity. Like mismatched bases, the introduction of central UNA bases disrupts the potential for cleavage of substrate by argonaute 2 (AGO2) during gene silencing. UNA-substituted duplexes are as effective as other strategies for allele-selective silencing of trinucleotide repeat disease genes. Modulation of AGO2 activity by the introduction of UNA substitutions demonstrates that backbone flexibility is as important as base pairing for catalysis of fully complementary duplex substrates. UNA can be used to tailor RNA silencing for optimal properties and allele-selective action. PMID:24266403

    Presentamos un estudio de caso de una adolescente puertorriqueña con comportamiento suicida. Esta comenzó una Terapia Socio Cognitivo-Conductual para el Comportamiento Suicida (TSCC-CS) de tipo ambulatorio luego de una hospitalización por intento suicida. La TSCC-CS incorpora una perspectiva ecológica y de desarrollo a la terapia cognitivo-conductual. Inicialmente mostró baja autoestima y severos síntomas depresivos y de ansiedad. Al finalizar el tratamiento, manifestó un cambio significativo en su sintomatología clínica y evidenció una mejoría en sus destrezas de manejo. No presentó ideas suicidas durante meses previos, ni durante el seguimiento. El análisis de este caso permitió realizar cambios en el protocolo de tratamiento, particularmente en las sesiones de familia y de comunicación con el fin de aumentar la viabilidad del tratamiento.

    Introducción: El neumoencéfalo a tensión luego de la cirugía transesfenoidal es poco común. En la literatura existen pocos casos reportados en los cuales el aire se encuentra localizado exclusivamente en las regiones selar y supraselar, constituyendo un pneumatocele selar. En este artículo se describe un caso inusual de pneumatocele selar a tensión de presentación tardía. Descripción del caso: Una mujer de 57 años consultó por hemianopsia bitemporal. Previamente, ya se le había realizado una cirugía transnasal por un adenoma hipofisario y se le había colocado una derivación lumbo-peritoneal por la presencia de una fístula de líquido cefalorraquídeo. Además, se le había realizado una resección transcraneal de un componente intracavernoso del tumor y radiocirugía debido a la agresividad del mismo. Se llevó a cabo una resonancia magnética que demostró un pneumatocele selar y supraselar. Intervención: Se realizó un abordaje transciliar. La región selar estaba encapsulada por tejido cicatrizal debido a los procedimientos previos. Se abrió la cicatriz y el aire fue evacuado. Posteriormente, el piso selar fue cerrado con grasa y cola de fibrina. Despuós del procedimiento, su campo visual retornó a la normalidad. Un año después de su última cirugía, continua asintomática. Conclusión: El pneumatocele selar y supraselar a tensión es un hallazgo extremadamente raro luego de una cirugía transesfenoidal. Su manifestaciónw clínica sería la alteración visual debida a la compresión inferior de la vía óptica. El pneumatocele selar a tensión debe ser evacuado en un corto plazo. PMID:23596554

    de haber sufrido gran presión por adoptar el idioma de los colonizadores, es una buena señal de fuerte identidad. Pero como todo, tampoco es tan simple. En el norte de Centroamérica, el nahua siguió siendo una lengua franca durante la primera... mitad de la época colonial, incluso entre los españoles, y de hecho ésta es la razón por la que se encuentran todavía tantas palabras nahuas en el español del la región.
