    Trognitz, B R; Hermann, M

    2001-05-01

    Frequencies of floral morphs in progenies obtained from a complete set of diallelic crosses among three accessions of tristylous, octoploid oca (Oxalis tuberosa) were used for a Mendelian analysis of floral morph inheritance. The frequencies observed had the best fit to a model of tetrasomic inheritance with two diallelic factors, S, s and M, m, with S being epistatic over M. No explanation could be found for the unexpected formation of a small percentage of short-styled individuals in crosses between the mid-styled and the long-styled parent. For the acceptance of models of disomic and octosomic inheritance several additional assumptions would have to be made and therefore these modes of inheritance are less likely. Dosage-dependent inheritance of floral morph was rejected. Only a small frequency (36%) of the cross progenies flowered, in contrast to the greater propensity for flowering of O. tuberosa accessions held at gene banks.

    The 'Oxalis tuberosa alliance' is a group of Andean Oxalis species allied to the Andean tuber crop O. tuberosa Molina (Oxalidaceae), commonly known as 'oca'. As part of a larger project studying the origins of polyploidy and domestication of cultivated oca, flow cytometry was used to survey DNA ploidy levels among Bolivian and Peruvian accessions of alliance members. In addition, this study provided a first assessment of C-values in the alliance by estimating nuclear DNA contents of these accessions using chicken erythrocytes as internal standard. Ten Bolivian accessions of cultivated O. tuberosa were confirmed to be octoploid, with a mean nuclear DNA content of approx. 3.6 pg/2C. Two Peruvian wild Oxalis species, O. phaeotricha and O. picchensis, were inferred to be tetraploid (both with approx. 1.67 pg/2C), the latter being one of the putative progenitors of O. tuberosa identified by chloroplast-expressed glutamine synthetase data in prior work. The remaining accessions (from 78 populations provisionally identified as 35 species) were DNA diploid, with nuclear DNA contents varying from 0.79 to 1.34 pg/2C.

    Nootropic effect of alcoholic (ALE; 50, 75, 100 mg/kg) and aqueous (AQE; 100, 200, 400 mg/kg) extracts of P. tuberosa was evaluated by using Elevated Plus Maze (EPM), scopolamine-induced amnesia (SIA), diazepam-induced amnesia (DIA), clonidine-induced (NA-mediated) hypothermia (CIH), lithium-induced (5-HT mediated) head twitches (LIH) and haloperidol-induced (DA- mediated) catalepsy (HIC) models. Piracetam was used as the standard drug. A significant increase in inflexion ratio (IR) was recorded in EPM, SIA and DIA models. A significant reversal effect was observed on rectal temperature in CIH model, reduction of head twitches in LIH models. However no significant reduction in catalepsy scores in HIC models were observed with test extracts and standard piracetam. The results indicate that nootropic activity observed with ALE and AQE of tuber extracts of P. tuberosa could be through improved learning and memory either by augmenting the noradrenaline (NA) transmission or by interfering with 5-hydroxytryptamine (5-HT) release. Further, the extracts neither facilitated nor blocked release of the dopamine (DA). Thus ALE and AQE elicited significant nootropic effect in mice and rats by interacting with cholinergic, GABAnergic, adrenergic and serotonergic systems. Phytoconstituents like flavonoids have been reported for their nootropic effect and these are present in both ALE and AQE extracts of tubers of P. tuberosa (Roxb) and these active principles may be responsible for nootropic activity.

    The ‘Oxalis tuberosa alliance’ is a group of Andean Oxalis species allied to the Andean tuber crop O. tuberosa Molina (Oxalidaceae), commonly known as ‘oca’. As part of a larger project studying the origins of polyploidy and domestication of cultivated oca, flow cytometry was used to survey DNA ploidy levels among Bolivian and Peruvian accessions of alliance members. In addition, this study provided a first assessment of C‐values in the alliance by estimating nuclear DNA contents of these accessions using chicken erythrocytes as internal standard. Ten Bolivian accessions of cultivated O. tuberosa were confirmed to be octoploid, with a mean nuclear DNA content of approx. 3·6 pg/2C. Two Peruvian wild Oxalis species, O. phaeotricha and O. picchensis, were inferred to be tetraploid (both with approx. 1·67 pg/2C), the latter being one of the putative progenitors of O. tuberosa identified by chloroplast‐expressed glutamine synthetase data in prior work. The remaining accessions (from 78 populations provisionally identified as 35 species) were DNA diploid, with nuclear DNA contents varying from 0·79 to 1·34 pg/2C. PMID:12102530

    The aim of this research is to study antidiabetic activity of root extract of Ruellia tuberosa L on rats (Rattus novergicus) induced by multiple-low dose streptozotocin as animal diabetic models. The parameters investigated were blood glucose levels, free radicals (MDA, malondialdehyde) levels and hepatic histopathology. The main materials used were n-hexane root extracts from Ruellia tuberosa L. Three groups of rats, including control group (group I), diabetic group (group II), and therapy group with Ruellia tuberosa L (group III), were used. Streptozotocin was given at multiple-low dose of 20 mg/kg of body weight for 5 times in 5 consecutive days i.p. to rats in groups II and III. The Ruellia tuberosa L extracts were then given orally for group III in the dose of 250 mg/kg of body weight per day for 3 weeks. Results of the current work showed that root extract Ruellia tuberosa L had lowered blood glucose levels on rats in group III by 60.3%, from 299.7 ± 24.7 mg/dL up to 119.0 ± 26.6 mg/dL. Moreover, the antidiabetic activity of Ruellia tuberosa L extracts also deduced from decrease of MDA levels in group III, from 3.5 ± 0.3 μg/mL up to 1.7 ± 0.4 μg/mL. The recovery of hepatic organ from treatment group has also been proven from the its histology profiles stained with hematoxylin-eosin.

    Magnetotelluric (MT) and transient electromagnetic (TEM) data were acquired by students from the Summer of Applied Geophysical Experience (SAGE) to construct structural models in and around the Caja del Rio Plateau, New Mexico. The Caja del Rio is located on the La Bajada-Jemez constriction that separates the Española and Santa Domingo basins in the Rio Grande Rift. The Rio Grande Rift, the result of tectonic extensional forces, extends approximately north-south across northern New Mexico. MT data collected in 2016 were merged with that from previous years to make up an 11 km north line and a 16 km south line extending from the west side of the Caja Del Rio to the east off the plateau in the Old Buckman Road area. The resistivity distributions revealed in one-dimensional (1-D) and two-dimensional (2-D) inverse models show some robust features. Models of the north are interpreted as a top resistive layer (convention) point in the northwest direction towards the conductive Valles Caldera. The MT models are consistent with geologic interpretations of the stratigraphic units. In addition, models disclose an additional conductive layer below the basement that we interpret as the mid-crustal conductor. Transient electromagnetic (TEM) data were collected in seven locations atop the Caja del Rio plateau in an attempt to identify the basal contact of the Cerros del Rio volcanic field, which, in turn, allow for the thickness of these basaltic and andesitic deposits to be mapped across the plateau. One-dimensional inverse models produced from the TEM data were aligned and interpreted geologically. A resistive ( 1000 ohm-m) unit, interpreted to represent the Cerros del Rio volcanics, thickens from 70m to 175m from southeast to northwest. The volcanics are overlain by a thin conductor, interpreted as weathered material. The resistive body is underlain by a thicker conductor, interpreted as sedimentary rocks of the Tertiary-aged Santa Fe Group.

Studies on Ceratitis capitata, a world fruit pest, can aid the implementation of control programs by determining the plants with higher vulnerability to attacks and plants able to sustain their population in areas of fly distribution. The objective of the present study was to evaluate the influence of eight tropical fruits on the following biological and behavioral parameters of C. capitata: emergence percentage, life cycle duration, adult size, egg production, longevity, fecundity, egg viability, and oviposition acceptance. The fruits tested were: acerola (Malpighia glabra L., cashew (Anacardium occidentale L., star fruit (Averrhoa carambola L., guava (Psidium guajava L., soursop (Annona muricata L., yellow mombin (Spondias mombin L., Malay apple (Syzygium malaccense L., and umbu (Spondias tuberosa L.. The biological parameters were obtained by rearing the recently hatched larvae on each of the fruit kinds. Acceptance of fruits for oviposition experiment was assessed using no-choice tests, as couples were exposed to two pieces of the same fruit. The best performances were obtained with guava, soursop, and star fruit. Larvae reared on cashew and acerola fruits had regular performances. No adults emerged from yellow mombin, Malay apple, or umbu. Fruit species did not affect adult longevity, female fecundity, or egg viability.

    2002-07-01

    In continuing study of the origins of the octoploid tuber crop oca, Oxalis tuberosa Molina, we used phylogenetic analysis of DNA sequences of the chloroplast-active (nuclear encoded) isozyme of glutamine synthetase (ncpGS) from cultivated oca, its allies in the "Oxalis tuberosa alliance," and other Andean Oxalis. Multiple ncpGS sequences found within individuals of both the cultigen and a yet unnamed wild tuber-bearing taxon of Bolivia were separated by molecular cloning, but some cloned sequences appeared to be artifacts of polymerase chain reaction (PCR) recombination and/or Taq error. Nonetheless, three classes of nonrecombinant sequences each joined a different part of the O. tuberosa alliance clade on the ncpGS gene tree. Octoploid oca shares two sequence classes with the Bolivian tuber-bearing taxon (of unknown ploidy level). Fixed heterozygosity of these two sequence classes in all ocas sampled suggests that they represent homeologous loci and that oca is allopolyploid. A third sequence class, found in eight of nine oca plants sampled, might represent a third homeologous locus, suggesting that oca may be autoallopolyploid, and is shared with another wild tuber-bearing species, tetraploid O. picchensis of southern Peru. Thus, ncpGS data identify these two taxa as the best candidates as progenitors of cultivated oca.

    The occurrence of yeasts on ripe fruits and frozen pulps of pitanga (Eugenia uniflora L), mangaba (Hancornia speciosa Gom.), umbu (Spondias tuberosa Avr. Cam.), and acerola (Malpighia glaba L) was verified. The incidence of proteolytic, pectinolytic, and mycocinogenic yeasts on these communities was also determined. A total of 480 colonies was isolated and grouped in 405 different strains. These corresponded to 42 ascomycetous and 28 basidiomycetous species. Candida sorbosivorans, Pseudozyma antarctica, C. spandovensis-like, C. spandovensis, Kloeckera apis, C. parapsilosis, Rhodotorula graminis, Kluyveromyces marxianus, Cryptococcus laurentii, Metchnikowia sp (isolated only from pitanga ripe fruits), Issatchenkia occidentalis and C. krusei (isolated only from mangaba frozen pulps), were the most frequent species. The yeast communities from pitanga ripe fruits exhibited the highest frequency of species, followed by communities from acerola ripe fruits and mangaba frozen pulps. Yeast communities from frozen pulp and ripe fruits of umbu had the lowest number of species. Except the yeasts from pitanga, yeast communities from frozen pulp exhibited higher number of yeasts than ripe fruit communities. Mycocinogenic yeasts were found in all of the substrates studied except in communities from umbu ripe fruits and pitanga frozen pulps. Most of the yeasts found to produce mycocins were basidiomycetes and included P. antarctica, Cryptococcus albidus, C. bhutanensis-like, R. graminis and R. mucilaginosa-like from pitanga ripe fruits as well as black yeasts from pitanga and acerola ripe fruits. The umbu frozen pulps community had the highest frequency of proteolytic species. Yeasts able to hydrolyse casein at pH 5.0 represented 38.5% of the species isolated. Thirty-seven percent of yeast isolates were able to hydrolyse casein at pH 7.0. Pectinolytic yeasts were found in all of the communities studied, excepted for those of umbu frozen pulps.

    Twenty pregnane glycosides, tuberoside A(1)-L(5), were isolated from the diethyl ether-soluble fraction of the MeOH extract from the aerial parts of Asclepias tuberosa (Asclepiadaceae). The pregnane glycosides were composed of 8,12;8,20-diepoxy-8,14-secopregnane as aglycon, and D-cymarose, D-oleandrose, D-digitoxose and/or D-glucose as the component sugars. Their structures were established using NMR spectroscopic analysis and chemical methodologies.

    Plant growth can be promoted by the application of apple fruit fermentation (AFF), despite unclear of the underlying mechanisms, the effects involved in AFF on rhizosphere microorganisms have been hypothesized. We investigated the consequences of applying AFF alone or in combination with Bacillus licheniformis to strawberry tissue culture seedlings in vitro, the analyses of Denaturing Gradient Gel Electrophoresis (DGGE) and 16S rDNA were performed to determine AFF effects on rhizosphere. Moreover, the growth index and antioxidant enzyme activities were determined 30 days after treatments. We identified five dominant bacteria in AFF: Coprinus atramentarius, Bacillus megaterium, Bacillus licheniformis, Weissella and B. subtilis. The greatest number of bacterial species were observed in the rhizosphere of control matrix (water treated), and the lowest diversity appeared in the rhizosphere soil treated with 108 cfu/mL B. licheniformis alone. Combining AFF plus B. licheniformis in one treatment resulted in the largest leaf area, plant height, root length, plant weight, and the markedly higher activities of antioxidant enzymes. We conclude that a combination of AFF plus B. licheniformis treatment to matrix can increase antioxidant enzymes activities in strawberry seedlings, optimize the status of rhizosphere microbial, and promote plant growth.

    Previously, phytochemical investigation of the roots of Asclepias tuberosa (Asclepiadaceae) led to the isolation of some 8,12;8,20-diepoxy-8,14-secopregnane tri-, tetra-, and penta-glycosides. An additional eight new minor 8,12;8,20-diepoxy-8,14-secopregnane glycosides were afforded in the recent investigation of this plant. These glycosides consisted of six or seven 2,6-dideoxy-hexopyranoses together with the aglycone, tuberogenin. The structures of each of these compounds were established using NMR, mass spectroscopic analysis and chemical evidence. As 8,12;8,20-diepoxy-8,14-secopregnane-type glycosides were observed only in A. tuberosa, these compounds were considered to be characteristic phytochemicals of this plant.

    Different habitat conditions can be responsible for the production of secondary metabolites and for the antioxidant properties of plant products. Thus, the aim of this study was to evaluate whether the antioxidant activity and tannin concentrations in the stem bark of Spondias tuberosa Arruda (Anacardiaceae) varied with collection site. The bark was collected from 25 individual trees, distributed in five different landscape units, as follows: agroforestry gardens, areas of pastures, maize cultivation areas, mountain areas and mountain bases, with the former 3 being considered as anthropogenic habitats, and the latter 2 considered as habitats with native coverage. The study was conducted in the rural area of the city of Altinho, Pernambuco State (Northeast Brazil). The DPPH (1,1-diphenyl-2-picrylhydrazyl) method was used to measure the antioxidant activity and tannin concentrations were evaluated by using the radial diffusion method. The results demonstrated that there were no significant differences among the tannin concentrations of the individuals from the native (6.27% ± 1.75) or anthropogenic areas (4.63% ± 2.55), (H = 2.24; p > 0.05). In contrast, there were significant differences (H = 5.1723; p 0.05) or in the anthropogenic areas (r = 0.38; p > 0.05). Because the variation of the antioxidant capacity of S. tuberosa bark was not accompanied by a variation in the tannin concentration, this property may be related to the presence of other metabolite(s).

    Full Text Available Systemic lupus erythematosus (SLE is an autoimmune disease that causes multiple organ damage. Although recent genome-wide association studies (GWAS have contributed to discovery of SLE susceptibility genes, few studies has been performed in Asian populations. Here, we report a GWAS for SLE examining 891 SLE cases and 3,384 controls and multi-stage replication studies examining 1,387 SLE cases and 28,564 controls in Japanese subjects. Considering that expression quantitative trait loci (eQTLs have been implicated in genetic risks for autoimmune diseases, we integrated an eQTL study into the results of the GWAS. We observed enrichments of cis-eQTL positive loci among the known SLE susceptibility loci (30.8% compared to the genome-wide SNPs (6.9%. In addition, we identified a novel association of a variant in the AF4/FMR2 family, member 1 (AFF1 gene at 4q21 with SLE susceptibility (rs340630; P = 8.3×10(-9, odds ratio = 1.21. The risk A allele of rs340630 demonstrated a cis-eQTL effect on the AFF1 transcript with enhanced expression levels (P<0.05. As AFF1 transcripts were prominently expressed in CD4(+ and CD19(+ peripheral blood lymphocytes, up-regulation of AFF1 may cause the abnormality in these lymphocytes, leading to disease onset.

    Many crops are polyploids, and it can be challenging to untangle the often complicated history of their origins of domestication and origins of polyploidy. To complement other studies of the origins of polyploidy of the octoploid tuber crop oca (Oxalis tuberosa) that used DNA sequence data and phylogenetic methods, we here compared AFLP data for oca with four wild, tuber-bearing Oxalis taxa found in different regions of the central Andes. Results confirmed the divergence of two use-categories of cultivated oca that indigenous farmers use for different purposes, suggesting the possibility that they might have had separate origins of domestication. Despite previous results with nuclear-encoded, chloroplast-expressed glutamine synthetase suggesting that O. picchensis might be a progenitor of oca, AFLP data of this species, as well as different populations of wild, tuber-bearing Oxalis found in Lima Department, Peru, were relatively divergent from O. tuberosa. Results from all analytical methods suggested that the unnamed wild, tuber-bearing Oxalis found in Bolivia and O. chicligastensis in NW Argentina are the best candidates as the genome donors for polyploid O. tuberosa, but the results were somewhat equivocal about which of these two taxa is the more strongly supported as oca's progenitor.

    Full Text Available The caja (Spondias mombin L. is used in the manufacture of ice-cream, jams, pulps, beverages being also consumed in natura. One of the most important procedures in food conservation is drying, considering that most fresh fruits contain approximately 80% of water. Food drying is used to obtain two basic aspects: (1 the economic factor; in the shipping and handling of the product; (2 at the manipulation; once dried and grinded, the material is rehydrated, at desirable levels, to formulate a new product as in ice cream, jams, yoghurts and drinks and may also be added to pasta, biscuits and other industrialized products. The aim of this study was to investigate the kinetics of caja bagasse drying in a fixed-bed tray dryer, using central composite factorial planning. The following factors were evaluated: temperature (55, 65 and 75 ºC, dryer inlet air velocity (3.2, 4.6 and 6.0 m.s-1 and cake thickness (0.8, 1.2 and 1.6 cm where the response of the considered variable was caja bagasse moisture content (b.s. and the results showed that the main effects and their interactions were significant at a 95% confidence level being the best condition obtained at temperature of 75 ºC, velocity of 6.0 m.s-1 and cake thickness of 0.8 cm.

    The aim of the present study was to evaluate the effect of turmeric (Curcuma longa) as additive in the diet for Astyanax aff. bimaculatus. Fish (0.83 ± 0.04 g) were fed, for 60 days, with six diets containing 0.0, 20.0, 40.0, 60.0, 80.0, and 100.0 g turmeric kg -1 feed. There was an increasing linear effect of turmeric on the thickness of the muscular layer, and height and width of the folds of the intestine. In the liver, a quadratic effect was observed of turmeric on the percentage of hepatocyte cytoplasm and a decreasing linear effect on the percentage of sinusoid capillaries. A quadratic effect was also observed of turmeric on the liver glycogen. There was no effect of turmeric on the antioxidant activity in the liver, carcass composition or productive performance of the fish. Thus, we concluded that Curcuma longa has trophic effects on the epithelium and the muscular layer of the intestine of A. aff. bimaculatus. Additionally, low levels of Curcuma longa cause increased deposition of liver glycogen and high levels cause reduction.

En este artículo, tras delimitar las unidades de análisis básicas para los sistemas de información de las cajas rurales y las cajas de ahorros, presentamos los resultados obtenidos a través de una encuesta realizada en dichas entidades, al objeto de contrastar la importancia que ostentan dichas unidades de análisis en sus sistemas de información. El estudio empírico llevado a cabo ha puesto de manifiesto que la unidad de análisis por excelencia en ambas categorías de entidades es la oficina, seguida por las direcciones regionales o de zona. Los productos y los clientes presentan un menor grado de implantación en sus sistemas de información, en especial en las cajas rurales. The basic units of analysis for managing Depository Financial Institutions are the central axes where management accounting information should be generated and, consequently, are also formed as an essential instrument to support the managerial decisions. Once the basic analysis units for information systems in the rural and savings banks are defined, we offer the results obtained by means of a survey carried out in the aforementioned institutions. So the relevance of this analysis unit in their information systems may be known. The empirical study carried out has shown that the main analysis unit in both categories of entities is the branch office, followed by regional management. Products and customers have a minor relevance in their information systems, particularly in the rural banks.

    durante el periodo colonial. El estallido de movimientos independentistas, autonomistas y realistas en varias regiones del Virreinato rápidamente produjo una crisis fiscal que implicó la transformación del mecanismo de financiación del gasto y la profundización de tendencias de crisis iniciadas en las últimas décadas del periodo colonial en algunos ramos específicos. El trabajo estudia la naturaleza de estas transformaciones comparando la estructura del gasto e ingreso de los últimos años de dominación colonial con la estructura que estos adquirieron en los años de la Primera República, entre 1811 y 1815. Como fuente, se utiliza material inédito derivado de la contabilidad de la Caja Real y de la Tesorería de Santafé, en particular los cortes y tanteos de cuentas producidos por la Caja Real entre 1803 y 1815.

    1999-12-01

    Oca (Oxalis tuberosa Mol.) or New Zealand yam, in common with other members of this genus, contains oxalate, an antinutritive factor. Twelve South American and two New Zealand cultivars of oca were analyzed for total and soluble oxalate contents of the tubers. The range of total oxalate levels was 92-221 mg/100 g of fresh weight. Levels of soluble and total oxalate extracted from the tubers were not significantly different, suggesting that no calcium oxalate is formed in the tubers. The oxalate concentrations obtained in this study for oca suggest that previously reported values are too low and that oca is a moderately high oxalate-containing food. This is the first report of a tuber crop containing moderate to high levels of soluble oxalates in the tubers and no insoluble oxalates.

    Diego de Paula Cognato

    Full Text Available The reproductive period and its relation with somatic and abiotic factors, the relative and absolute fecundity, spawning type, length of first maturation and sex ratio is describe for Gymnotus aff.carapo from a small lake at Itapuã State Park, Rio Grande do Sul, Brazil. Gymnotus aff. carapo presents a relatively long reproductive cycle extending from November/2003 to March/2004. Decreases in water conductivity and increases in dissolved oxygen are correlated with increased gonadal development in males. In females, seasonal increases in temperature and photoperiod and decreases in dissolved oxygen are correlated with increased gonadal development. The mean absolute fecundity was 915.3 oocytes, and mean relative fecundity 0.20 oocytes/mg body weight. Egg size distributions indicate multiple spawning. The size of first maturation was 141 mm in females and 146 mm in males. The sex ratio was 1:1, with a male bias only in smaller size classes.

    The characteristic flavor of exotic tropical fruits is one of their most attractive attributes to consumers. In this article, the enormous diversity of exotic fruit flavors is reviewed. Classifying some of the exotic fruits into two classes on the basis of whether esters or terpenes predominate in the aroma was also attempted. Indeed, as far as exotic tropical fruits are concerned, the majority of fruits have terpenes predominating in their aroma profile. Some of the fruits in this group are the Amazonian fruits such as pitanga, umbu-caja, camu-camu, garcinia, and bacuri. The ester group is made up of rambutan, durians, star fruit, snake fruit, acerola, tamarind, sapodilla, genipap, soursop, cashew, melon, jackfruit, and cupuacu respectively. Also, the role of sulphur-volatiles in some of the exotic fruits is detailed.

    It is believed that soluble oxalate has higher bioavailability than insoluble oxalate. Oca (Oxalis tuberosa) is moderately high in oxalate and contains oxalate in soluble form only. We estimated the bioavailability of oxalate in oca based on the urinary excretion of oxalate after oxalate loading with oca to estimate the bioavailability of oxalate in oca. We also clarified whether bioavailability differs in various oxalate loads from the same food source and studied the effect of an additional calcium source on the bioavailability of oxalate from oca. Four men and 4 women ingested 50, 100 and 150 gm. oca as well as 100 gm. oca with 100 gm. sour cream. Oxalate was measured in a 6-hour urine sample from each volunteer. The mean bioavailability of oxalate from oca plus or minus standard deviation was 1.44% +/- 1.31% during the 6-hour period after intake. There was no significant difference in oxalate bioavailability among oxalate intake levels in this study, although oca consumption with sour cream significantly decreased the uptake of oxalate (p oca appears to be similar to that in spinach. However, bioavailability varies among individuals and depends on other constituents of a combined meal.

    Abstract A new species of Pristimantis is described from the highland paramos on the eastern slopes of the Cajas Massif, southern Andes of Ecuador, at 3400 m. This new species is characterized by having a distinctive reddish color, cutaneous macroglands in suprascapular region and surfaces of arm and legs, and by lacking dentigerous processes of vomers. The cutaneous macroglands are similar to those exhibited by several species of the Pristimantis orcesi group, and may suggest a close phylogenetic relationship. The new species could be a latitudinal substitution of Pristimantis orcesi in the southern Andes of Ecuador. PMID:29713233

    Full Text Available In contrast to crops, there are fewer studies using LED-based light with green microalgae and none cultivating the microalga Isochrysis aff. galbana (T-ISO even though of its importance in marine aquaculture. The objective was to evaluate of white and red LEDs as an alternative source of light to cultivate I. aff. galbana (T-ISO. In order to carry this out white and red LEDs were used with a laboratory built Erlenmeyer-type photobioreactor to determine productivity, cell number and size and biomass composition. Results were compared with standard fluorescent lights of the same light intensity. The culture system consisted of 3 flasks for applying red LEDs and three for white LEDs and 3 control group flasks illuminated with the normal fluorescent lighting at the similar light intensity of ~60 mM m–2 s–1. It was found that the population cell density did not significantly increase with either red LEDs or white LEDs (p > 0.05, if at all. Standard fluorescent lighting (control group showed significant increases in population cell number (p < 0.05. Through microscopic observation cell size was found to be smaller for white LEDS and even smaller for red LEDs compared to fluorescent lighting. Biochemical composition of proteins, carbohydrates and lipids was similar for all light regimes. The authors suggest that the unexpected non-growth I. aff. galbana (T-ISO, a haptophyte microalga, with white and red LEDs is possibly due to fact that to initiate cell growth this microalgae requires other wavelengths (possibly green besides red and blue, to allow other pigments, probably fucoxanthin, to capture light

    Root fluorescence is a phenomenon in which roots of seedlings fluoresce when irradiated with ultraviolet (UV) light. Soybean (Glycine max) and rye grass (Elymus glaucus) are the only plant species that have been reported to exhibit this occurrence in germinating seedling roots. The trait has been useful as a marker in genetic, tissue culture and diversity studies, and has facilitated selection of plants for breeding purposes. However, the biological significance of this occurrence in plants and other organisms is unknown. Here we report that the Andean tuber crop species Oxalis tuberosa, known as oca in the highlands of South America, secretes a fluorescent compound as part of its root exudates. The main fluorescent compounds were characterized as harmine (7-methoxy-1-methyl-beta-carboline) and harmaline (3, 4-dihydroharmine). We also detected endogenous root fluorescence in other plant species, including Arabidopsis thaliana and Phytolacca americana, a possible indication that this phenomenon is widespread within the plant kingdom.

    Full Text Available Ten-story building on a slope, with following distribution: tellers desks, offices and administrative departments, reserved and rental space, a cafeteria, meeting room, installation rooms and a swimming pool with its corresponding services, located on the top of the building. It also has five basements for supplies, storage and garage. The site is surrounded on all four sides with streets on different levels which permit various entrances and different vertical Communications between floors, which results in an optimum relationship between the passage surface and the usable space, taking full advantage of the space available. The concrete structure, with 8.30 m reticule on the sides, provides sufficient flexibility for adapting the different floors to the different operation schemes. The building offers a special architectural interest as a result of the offset in the upper floors and the contrast achieved in treating the facades, where the dark aluminum of the offices floors is broken by the bodies jutting out of the stairwells and elevators, treated with artificial white stone. The building is topped with a roof made of inclined facing on the last floor, also treated with dark aluminum panels.Este edificio consta de diez plantas sobre rasante, en fas que se distribuyen: una sala de cajas, oficinas y departamentos administrativos, espacios de reserva y alquiler, una cafetería, salón de actos, cuartos de instalaciones, y una piscina, con sus correspondientes servicios, montada en el remate de la edificación.

    Full Text Available This study described the feeding habits of the characin Astyanax aff. fasciatus. The diet compositions of specimens from two sites (A and B on a river in Southern Brazil were compared according to the size of individuals and seasonal period. The collections were performed monthly from March 2005 to February 2006, where the stomach contents of 290 specimens were assessed. Food items for A. aff. fasciatus were basically composed of plants and insects, especially leaf fragments, seeds, fruits, filamentous algae, aquatic and terrestrial insects and insect fragments. At site A, the most common items were insect and plant fragments. Conversely at site B, plant fragments were more representative. In general, all items of animal origin showed the highest feeding index values at site A, whereas at site B detritus and grass items were more abundant. The composition of items varied seasonally, with higher diversity of items being recorded during the spring at both sites. Smaller individuals preferred items of animal origin, while the larger ones consumed mainly items of plant origin. According to its size, A. aff. fasciatus in this study may be considered a species with insectivorous tendencies when immature or herbivorous tendencies when adult. Nevertheless, its feeding habits may be flexible according to resource availability, showing wide ontogenetic, besides spatial and temporal variation.

    Full Text Available There are evidences that Bryconamericus aff. iheringii represents a species complex. DNA molecular markers have been effective in studies on phylogeny, taxonomy, and identification of cryptic species. In this study, partial sequences of genes of ATPase 6 and 8 were used to assess genetic diversity within and among populations of B. aff. iheringii of sub-basins of Tibagi, Pirapó and Ivaí rivers, belonging to the Upper Paraná river basin. The analysis of the sequences of genes pointed out high genetic diversity in B. aff. iheringii from the sub-basins studied with genetic distance values comparable to those found among different species. There was a division of the individuals into five groups. The comparison with other species of Bryconamericus that have sequences available in GenBank confirmed that the individuals studied have relevant values of genetic distance, found among different species. Nevertheless, with the available data it is not possible to refute the hypothesis that the populations correspond to a group resulting from hybridization or that there might have been introgression of mitochondrial DNA among different species.

    High-performance liquid chromatography (HPLC)-diode array detection (DAD)-mass spectrometry (MS) techniques have been successfully employed in the identification of the anthocyanins of the coloured tubers of isla oca (Oxalis tuberosa), the second most cultivated tuber in the Andean region. Tubers underwent a pre-treatment step in order to inhibit enzymatic reactions and to obtain a stable powder or "concentrate". This concentrate was dissolved, purified and then analysed. Eight different compounds were found. The major peaks were malvidin glucosides (malvidin 3-O-glucoside and 3,5-O-diglucoside). The rest of the peaks were 3,5-O-diglucosides of petunidin and peonidin, and 3-O-glucosides of delphinidin, petunidin and peonidin. Only malvidin 3-O-acetylglucoside-5-O-glucoside was found as an acylated anthocyanin.

    Both the biological control techniques as the Sterile Insect Technique (SIT), are used in many countries to control, suppress and even eradicate fruit flies and other pests in agriculture and public health. The use of such techniques minimizes the continuous employment of insecticides, protects the environment and conforms to standards for food safety. However, it is necessary to implement such programs, technology to produce millions of parasitoids and the pest in its own laboratory with biological quality similar to the insects found in nature and cost competitive with chemical control. The objectives of this study was to establish protocols for artificial rearing of A. sp. 1 aff. fraterculus in liquid larval diet that will achieve levels of mass production for a possible reduction in the cost of establishing and determining the dose of radiation sterilization of adult A. sp. 1 aff. fraterculus meeting the quality parameters required by the Sterile Insect Technique with insects from the creation of Radioentomology Laboratory of CENA/USP. Seven experimental diets compared to the conventional diet used in Radioentomology Lab. of CENA/USP, which was used as control. All seven diets have in common the exclusion of agar in its formulation. Only two of the diets tested were suitable for larval development of the fly, they compared with the standard diet, showed inferior results with respect to the volume of recovered larvae, pupae and weight of emergency, however, no significant differences regarding the periods of development , pupal recovery, sex ratio and longevity under stress. It is possible to replace the diet with agar for liquid diets for artificial creation of A. sp. 1 aff. fraterculus, reduced cost and greater convenience of handling, but due to their quality standards lower than the standard diet, more tests are needed especially regarding the adaptability of the insect to the new environment. To determine the sterilizing dose this study examined the

    Full Text Available Se realiza una revisión actualizada sobre las peculiaridades clínicas, radiológicas y neuropatológicas de la esclerosis tuberosa, la más representativa de las enfermedades neurocutáneas que evolucionan con manchas hipocrómicas y segunda en frecuencia de las facomatosis. Las manchas hipocrómicas asociadas con espasmos infantiles o cardiomegalia en lactantes y la evidencia de crisis epilépticas y angiofibromas faciales en la infancia tardía, constituyen las formas habituales de presentación de le enfermedad, aunque no es raro observar formas paucisintomáticas en la adultez. Los nódulos subependimarios, las tuberosidades corticales y los astrocitomas de células gigantes son las manifestaciones neuropatológicas características de este proceso, identificables radiológicamente mediante tomografía axial computadorizada y resonancia magnética nuclear craneales. El diagnóstico precoz permite brindar consejo genético a los padres; y la evaluación periódica de los casos, la identificación temprana de posibles complicaciones.An updated review on the clinical, radiological and neuropathological pecularities of tuberous sclerosis is made. This is the most representative of the neurocutaneous diseases that evolve with hypochromic stains and is the second in frequency of pharcomatosis. The hypochromic stains associated with infantile spasms or cardiomegaly in infants and the evidence of epileptic seizures and facial angiofibromas in late childhood are the habitual forms of presentation of this disease, although it is not rare to observe oligosymptomatic forms in adults. The subepindemal nodules, the cortical tuberosities and the astrocytomas of giant cells are the characteristic neuropathological manifestations of this process that may be radiologically identified by CAT and cranial magnetic resonance imaging. The early diagnosis allows to give genetic counseling to parents, to periodically evaluate the cases, and to identify the

Edessa es una de las plagas del camu camu que provoca sequedad en los brotes, y en los frutos una mancha decolorada con círculos concéntricos bien marcados y un punto central al alimentarse. El objetivo del presente trabajo fue determinar el ciclo biológico bajo condiciones de laboratorio y la fluctuación poblacional de Edessa aff. aulacosterna "Chinche del fruto del camu camu" durante enero a noviembre del 2004 en el cultivo de camu camu, en parcelas en desarrollo y producción ubicadas en áreas de restinga inundables en Pucallpa, Ucayali, Perú. Se colectaron huevos, ninfas y adultos procedentes del distrito de Yarinacocha, Pucallpa, Ucayali, Perú para iniciar la crianza artificial. El tiempo de duración del huevo al I estadio ninfal fue 5,1 días. Se encontró un 94,6% de eclosión de los huevos, variando entre 12 hasta 14 huevos por postura. El tiempo transcurrido desde el huevo hasta II estadío fue de 37,3 días y del III al V estadío ninfal fue de 81,9 días. El porcentaje de mortalidad del primer estadio ninfal a adulto fue de 98,1%. Los adultos colectados se localizaron preferentemente sobre las ramas y el tallo de la planta, mientras que las ninfas se encontraron en los brotes tiernos. Con relación a su fluctuación poblacional, solo se registró posturas a lo largo del año en parcelas en producción. No se encontraron diferencias entre ninfas I a V, y adultos de Edessa aff. aulacosterna, entre plantaciones en producción y desarrollo de camu camu. Solo se encontró diferencias entre la época seca y lluviosa en las ninfas de III a V estadio en las plantas de camu camu en desarrollo.

    Full Text Available Biological aspects of Leucothyreus alvarengai Frey and Leucothyreus aff. semipruinosus Ohaus (Coleoptera, Melolonthidae, Rutelinae in crop succession at central Brazil. Beetles of the family Melolonthidae make up a large group and some species are considered pests of planted crops. Little information is available on the basic biological aspects of the genus Leucothyreus, such as association with cultivated crops and their occurrence periods. Therefore studies were developed in soybean and corn crops in Tangará da Serra, Mato Grosso, Brazil, with the objective of studying the occurrence and biological aspects of Leucothyreus alvarengai Frey and Leucothyreus aff. semipruinosus Ohaus. For acquisition of immature specimens of both species, in April 2011 sampling was performed in corn fields, in July and October in the fallow area, and in soybeans fields planted in December; in 2012 sampling was performed in January and February in soybean fields and in March in corn fields. In 2011 the total number of larvae obtained in April, July, October and December were 100, 6, 30 and 27, and in January, February and March of 2012 these quantities were 32, 52 and 65 larvae, respectively. In all sampling events the larvae of L. alvarengai were collected in greater quantity. At the beginning of the reproductive period of L. alvarengai and L. aff. semipruinosus, it was observed that the adults began to fly and soon after started oviposition in the field in September. The appearance of larvae coincides with the time of soybean planting in the field, thus the larvae feed on roots of soybean plants at the beginning of their development and the cycle from egg to adult of the two species was completed in one year.

The objective of the present work is to analyze which are the effects that the financial crisis is causing in the Spanish small farm loan banks, starting off of the own characteristics of the small farm loan banks and considering the published most recent works on the present financial crisis. The surroundings of global financial crisis require a comparative characterization of the sector with the bank and the savings banks by means of the analysis of the rates of dilatoriness, cover of insolvencies and the granted ratings.

    Full Text Available Introdução: O Complexo de Esclerose Tuberosa (CET é uma síndrome neurocutânea transmitida hereditariamente, de traço autossômico dominante e que se manifesta por uma tríade clássica: deficiência mental, convulsões e adenoma sebáceo. A mutação responsável pela síndrome está presente em até 85% dos portadores de CET e.ocorre nos genes supressores tumorais TSC1 e TSC2, que produzem hamartina e tuberina, respectivamente.A prevalência do CET é de 1:10.000 a 1:170.000, atinge mais indivíduos do sexo masculina e é rara em negros. Relato de Caso: R.C.S.B., paciente do sexo feminino, 16 anos, vem encaminhada ao ambulatório de neurologia devido a quadro de convulsões tônico-clônicas generalizadas e crises de ausência diárias há 1 ano, mas com história de convulsões aos 2 anos que cessaram espontaneamente. Está em tratamento com fenitoína 200mg/dia e carbamazepina 800mg/dia, mas ainda apresenta crises de ausência. A paciente apresenta as lesões cutâneas típicas do CET: adenomas sebáceos (angiofibroma em face distribuídos simetricamente entre nariz e bochechas, envolvendo ainda fronte e queixo. Não há sinais de retardo mental. A ressonância nuclear magnética revelou imagens com padrão compatível com áreas de desmielinização. O eletroencefalograma encontrava-se normal. Conclusão: O tratamento do CET ainda é um desafio para muitos neurologistas, uma vez que não há tratamento específico para doença. A paciente deve contar com equipe multidisciplinar, por vezes é necessário acompanhamento com neurologista, dermatologista, geneticista, psicólogos e outros, dependendo das manifestações do CET. A finalidade terapêutica é a qualidade de vida da paciente, que pode ser prejudicada pelas várias convulsões ou alterações estéticas da doença.

    Full Text Available Las reformas legislativas que han afectado en los últimos tiempos a la organización y el funcionamiento del sistema financiero español han tenido una especial repercusión en el ámbito de las cajas de ahorros. La tramitación parlamentaria de la Ley 44/2002, de 22 de noviembre, de Medidas de Reforma del Sistema Fianciero, reavivó el debate sobre su régimen jurídico y la necesidad de acotar la intervención pública en su seno. Ahonda en ello la Ley 26/2003 , de 17 de julio, de Transparencia, que extiende al ámbito de las cajas la preocupación por el corporate governance. Ambas normas responden a la necesidad de dar respuesta a algunos de los problemas más inmediatos a que se enfrentan estas entidades, si bien adolecen de un defecto fundamental por cuanto no abordan de forma exhaustiva la regulación de la institución. Se perpetúa así la trayectoria tradicional de "parcheo" del régimen jurídico aplicable a las mismas, evitando entrar en la cuestión esencial de la definición de su naturaleza jurídica y abocando a las cajas, en consecuencia, al díficil reto de acompasar su vocación social tradicional a las nuevas exigencias legales en pro de una mayor eficiencia, racionalidad y neutralidad de su acitividad económica.Recent legal changes pertaining to the organization and performance of the Spanish financial system have had significant repercussions on the savings banks sector. The law on financial market reform passed in 2002, Ley Financiera, raised once again the debate on their legal situation and the urge to cut down public influence on their management. The 2003 Transparency Law, Ley de Transparencia, follows this reform and extends corporate governance to Spanish savings banks. Both Laws seek to confront some of the most important issues raised by these credit institutions, but they also share the flaw of not regulating its legal framework and status completely. They continue, therefore, to add "patches" to the savings

  1. Properties of Single K+ and Cl− Channels in Asclepias tuberosa Protoplasts 1

    Potassium and chloride channels were characterized in Asclepias tuberosa suspension cell derived protoplasts by patch voltage-clamp. Whole-cell currents and single channels in excised patches had linear instantaneous current-voltage relations, reversing at the Nernst potentials for K+ and Cl−, respectively. Whole cell K+ currents activated exponentially during step depolarizations, while voltage-dependent Cl− channels were activated by hyperpolarizations. Single K+ channel conductance was 40 ± 5 pS with a mean open time of 4.5 milliseconds at 100 millivolts. Potassium channels were blocked by Cs+ and tetraethylammonium, but were insensitive to 4-aminopyridine. Chloride channels had a single-channel conductance of 100 ± 17 picosiemens, mean open time of 8.8 milliseconds, and were blocked by Zn2+ and ethacrynic acid. Whole-cell Cl− currents were inhibited by abscisic acid, and were unaffected by indole-3-acetic acid and 2,4-dichlorophenoxyacetic acid. Since internal and external composition can be controlled, patch-clamped protoplasts are ideal systems for studying the role of ion channels in plant physiology and development.

    We had earlier reported that the extract of Pueraria tuberosa significantly inhibits DPP-IV enzyme, resulting in glucose tolerance response in rats. In this study, we have explored the active phytochemicals responsible for this potential. The results have been validated in both fasting and postprandial states in the plasma of normal rats and also in fasting blood and intestinal homogenates of diabetic models. Pueraria tuberosa water extract (PTWE) was administered to normal Charles Foster rats for 35 days and to diabetic model (65 mg/kg bw) for 10 days. After treatments, oral glucose tolerance test (OGTT) and insulin was done for 90 min, and the changes in the levels of GLP-1, GIP, and DPP-IV activities were monitored in fasting and postprandial states. In the case of the diabetic model, DPP-IV activity was measured in intestinal homogenate and basal insulin in plasma. The components of PTWE were analyzed via HPLC-MS based on their chemical formula, molecular mass, and retention time. Using the molecular docking study, we have selected the top five components having strong binding energy with DPP-IV. The increase in secretion of GLP-1 and GIP was significantly higher in the postprandial state when compared to fasting condition. GLP-1 plasma concentration increased by 5.8 and 2.9 folds and GIP increased by 8.7 and 2.4 folds in PTWE and control rats, respectively. In contrast, the postprandial decrease in DPP-IV specific activities was recorded at 2.3 and 1.4 folds. The response in OGTT and insulin was also consistent with these changes. In comparison to diabetic controls, PTWE-administered rats showed decreased DPP-IV activity in the intestine, leading to enhanced basal insulin concentration. Through molecular docking, we found Puerarone and Robinin to be the most potential phytochemicals of PTWE for DPP-IV inhibition. Binding energy (kcal/mol) and dissociation constant (pM) of Robinin with DPP-IV protein were found to be 7.543 and 2,957,383.75, respectively

    Full Text Available This article shows the economic significance of the group of mines that belonged to the jurisdiction of the «Caja de Guadalajara». The novelty lies in that local historiography had erroneously labeled these mining camps as being small. Recent studies show that they were not so small after all. These groups of mines were the focal point of the economy of a vast region and triggered the development of agriculture, livestock and trade activities. This article reveals the nexus between the fluctuations in silver production and events in Europe.

    Este artículo da a conocer la importancia económica que tuvo un conjunto de reales de minas que perteneció a la jurisdicción de la caja de Guadalajara. Es novedoso porque por primera vez son estudiados aquéllos que la historiografía local ha considerado erróneamente como «pequeños reales de minas». Estas explotaciones fueron el eje articulador de la economía en una vasta región que impulsó el desarrollo de la ganadería, agricultura y comercio. Vincula las fluctuaciones en la producción de plata con sucesos ocurridos en Europa.

    Both the biological control techniques as the Sterile Insect Technique (SIT), are used in many countries to control, suppress and even eradicate fruit flies and other pests in agriculture and public health. The use of such techniques minimizes the continuous employment of insecticides, protects the environment and conforms to standards for food safety. However, it is necessary to implement such programs, technology to produce millions of parasitoids and the pest in its own laboratory with biological quality similar to the insects found in nature and cost competitive with chemical control. The objectives of this study was to establish protocols for artificial rearing of A. sp. 1 aff. fraterculus in liquid larval diet that will achieve levels of mass production for a possible reduction in the cost of establishing and determining the dose of radiation sterilization of adult A. sp. 1 aff. fraterculus meeting the quality parameters required by the Sterile Insect Technique with insects from the creation of Radioentomology Laboratory of CENA/USP. Seven experimental diets compared to the conventional diet used in Radioentomology Lab. of CENA/USP, which was used as control. All seven diets have in common the exclusion of agar in its formulation. Only two of the diets tested were suitable for larval development of the fly, they compared with the standard diet, showed inferior results with respect to the volume of recovered larvae, pupae and weight of emergency, however, no significant differences regarding the periods of development , pupal recovery, sex ratio and longevity under stress. It is possible to replace the diet with agar for liquid diets for artificial creation of A. sp. 1 aff. fraterculus, reduced cost and greater convenience of handling, but due to their quality standards lower than the standard diet, more tests are needed especially regarding the adaptability of the insect to the new environment. To determine the sterilizing dose this study examined the

    Phytoremediation is a novel, solar-driven and cost-effective technology for the remediation of heavy metal contaminated environments through exploitation of plants ability to accumulate heavy metals in their harvestable shoot parts. In the present investigation, we collected plants of two species of Portulaca i.e. P. tuberosa and P. oleracea from field sites in Vadodra, Gujrat, India. At one site, field was being irrigated with industrial effluent while at other with tube well water. Analysis of heavy metals was performed in industrial effluent, tube well water, soils irrigated with them, and in different parts viz., roots, stem, leaves and flowers of the plant samples. Industrial effluent and soil irrigated with it had very high level of heavy metals (Fe, Zn, Cd, Cr and As) as compared to the tube well water and soil irrigated with that. Plants of both the species growing in effluent irrigated soils showed high accumulation of metals in all plant parts with the maximum being in roots and the least in flowers. Interestingly, both species of Portulaca hyperaccumulated more than one heavy metal viz., Cd, Cr and As. The total shoot concentrations (microg g(-1) dw) of Cd, Cr and As in P. tuberosa were 1,571, 7,957 and 3,118, respectively while in P. oleracea, these were 1,128, 7,552 and 2,476, respectively. Portulaca plants have good biomass and high regeneration potential; hence appear to be suitable for the remediation of effluent (metal) contaminated areas.

    Oca (Oxalis tuberosa Mol.) is an under-utilized tuber crop from the Andean region. Cryopreservation would allow the safe and long-term preservation of the genetic resources of this crop. A protocol for the cryopreservation of in vitro grown shoots has been developed using the vitrification solution PVS2. Two genotypes were studied (G1 and G27). Nodal segments were cultured on MS medium and incubated at 10 degree C with 16 h photoperiod and 10 mol per square meter per second irradiance, for two weeks. Apices were then excised and cultured on MS+0.15 M sucrose for 3 days at 5 degree C in darkness. Subsequently, apices were immersed in a loading solution (liquid MS medium+2 M glycerol+0.4 M sucrose), and then treated with the vitrification solution PVS2 for 0 to 40 minutes. Cryovials were then immersed in liquid nitrogen. Four weeks after rewarming and culture on recovery medium, genotype G1 showed approximately 60 percent recovery (normal growth) with 20 min PVS2 treatment. Genotype G27 showed lower recovery (30 percent). Differential scanning calorimetry yielded a Tg midpoint for PSV2 solution of ca. -120 degree C. Calorimetric studies on apices at different stages of the cryopreservation protocol showed a change in calorimetric parameters consistent with a decrease in the amount of frozen water as the protocol advanced.

    Full Text Available Black spot disease is common in freshwater fish and is usually caused by the metacercaria stage of digenetic trematodes, normally from the Diplostomidae family. The present study evaluated the prevalence and intensity of this disease in Astyanax aff. fasciatus(Teleostei: Characiformes in the Guaíba Lake basin (RS, Brazil, including body parts assessment and the points of sampling with higher occurrence of black spots. Fish samples were taken seasonally from December 2002 until October 2004. The samples were collected with the use of a seine net at eleven points. The specimens were fixed in 10% formalin and stored in 70% ethanol. Black spot disease showed a low frequency in the Guaíba lake basin (2.07% and no specificity to the species Astyanax aff. fasciatus was observed. A high prevalence among the individuals and high intensity of infection levels was found in the ventral and dorsal regions in relation to other body parts (e.g., pectoral, pelvic and anal regions. Among the sampling points studied, we observed a higher prevalence on samples collected at points Gasômetro, Saco da Alemoa and Sinos, located in open areas with less occurrence of mollusks.

    Full Text Available Introducción La fusión quirúrgica de la columna lumbar es un método muy utilizado para el tratamiento de la inestabilidad segmentaria lumbar dolorosa. En la actualidad, las dos técnicas de fusión instrumentada más utilizadas son la fusión posterolateral con tornillos pediculares y la fusión circunferencial mediante asociación de caja intersomática. Si bien hay evidencia de que la asociación de dispositivos intersomáticos aumenta la tasa de fusión, la mayoría de los estudios no discriminan si esta se produce solo de forma posterolateral o si se asocia una fusión anterior. El objetivo de este trabajo es determinar si existe fusión ósea real a nivel de las cajas intersomáticas o si estas actúan solo como espaciadores. Material y métodos Se analizaron 28 pacientes con patología de la columna lumbar sometidos a artrodesis lumbar circunferencial en un solo nivel entre mayo de 2007 y enero de 2012, mediante tomografía computarizada posquirúrgica para valorar la presencia o no de artrodesis anterior. Se efectuó un estudio de valor terapéutico, descriptivo, de observación (nivel de evidencia IV; mediante evaluación estadística se realizó un análisis de frecuencias para describir la proporción de casos con fusión anterior. Resultados Se detectó una tasa de fusión del 92,86% y falta de fusión radiológica anterior en el 7,14% de los pacientes. Conclusiones Hay una alta tasa de fusión anterior a nivel de las cajas intersomáticas; de este modo, se demuestra que dichos dispositivos actúan como medios de fusión y no solo como espaciadores.

    A pregnane glycoside fraction from the roots of Asclepias tuberosa L. caused normal human skin fibroblasts to proliferate. This fraction contained 21 pregnane glycosides whose structures were established using NMR spectroscopic analysis and chemical evidence. The aglycones of most of these compounds were identified as 8,12;8,20-diepoxy-8,14-secopregnanes, such as tuberogenin or 5,6-didehydrotuberogenin, the same aglycones as constituents of the aerial parts of this plant.

As larvas apresentaram boca subterminal durante todo o seu desenvolvimento. O tubo digestório se diferenciou em estômago e intestino apenas no estágio de pós-flexão. As larvas consumiram, principalmente, algas e microcrustáceos, o que permitiu caracterizá-las como planctófagas. A intensa modificação morfológica no trato digestório nos indivíduos em pósflexão coincidiu com o aumento na abundância de algas em relação aos itens de origemanimal; porém, de forma geral, a ocorrência aumentou para todos os itens. A análise do grau de digestão dos itens alimentares sugeriu que indivíduos em pré-flexão alimentaram-se, possivelmente, durante o dia, e os mais desenvolvidos, durante o entardecer e no períodonoturno.The aim of this study was to analyze some feeding treats of Bryconamericus aff. iheringii larvae, sampled in both the limnetic and littoral regions of the Piquiri River, in Santa Maria reservoir, between July and November 2001. The larvae presented sub-terminal mouth in larval period. The digestive tract differentiated in terms of stomach and intestine only in the postflexion larvae. The larvae fed mainly on algae and microcrustacea allowing to characterize them as planktivorous. The intense morphologic shift in the digestive tract in the postflexion larvae coincided with an increase in the abundance of algae in relation to animals items; however, in general, all the items had their occurrence increased. Analysis of the digestion stage suggested that preflexion larvae, possibly, fed themselves during the day, and those more developed, at dusk and night.

    The sediment record from Laguna Pallcacocha in Las Cajas National Park, southern Ecuador (4060 masl; 2°46'S; 79°14'W) has been interpreted to record El Niño floods spanning the Holocene (Rodbell et al., 1999; Moy et al., 2002). The sediment record is unusual for the nearly continuous dark- and light-colored laminations (0.1-2.0 cm thick) that comprise the Holocene. Light laminae typically have erosive basal contacts and fine-upwards, whereas dark laminae possess abrupt or gradational lower contacts and reveal no grain size trends. Light laminae contain 7%), and contain 3-10% biogenic silica. Light laminae represent deposition during periods of increased precipitation, mobilization of unvegetated sediment above the lake, and increased stream discharge, all of which generate density-driven undercurrents. Conversely, dark laminae are deposited relatively slowly by sedimentation of organic matter, some derived from surface soil horizons. Time series analysis of light laminae reveal the ENSO spectral signature (2-8 yr) that evolves through the Holocene. However, none of the sediment cores taken from many nearby lakes reveal an alluvial record comparable in terms of frequency and magnitude to that preserved in Pallcacocha thus raising questions as to the factors responsible for the rich stratigraphy preserved in Pallcacocha, and, moreover, the regional paleoclimatic significance of the Pallcacocha record. A review of lacustrine sediment cores obtained from Las Cajas National Park suggests that drainage basin factors are the primary control on the sedimentologic signal recorded. These factors include bedrock geology, presence of unvegetated sediment exposed on slopes, connectivity of exposed sediment to primary inflow streams, drainage basin slope, drainage basin:lake surface area ratio, and position of lake in paternoster sequence of lakes. Bedrock is comprised of Quaternary silicic ignimbrite, rhyolite, and andesite of the Tarqui Formation. Ignimibrite provides the

Objetivo: evaluar el potencial antiproliferativo, anticlonogénico y el efecto sobre el ciclo celular de los extractos hexánico y metanólico de la esponja Leucetta aff. floridana del Caribe colombiano en las líneas celulares leucemoides Jurkat y K562. Métodos: la viabilidad y proliferación celular se determinaron mediante el ensayo de azul de tripano a 0, 24, 48, 72 y 96 h. La eficiencia de clonación y el efecto sobre el ciclo celular se evaluaron a 10 y 100 µg/mL. Los datos se analizaron usando ANOVA multifactorial y la prueba Tukey. Resultados: el extracto hexánico presentó actividad antiproliferativa en ambas líneas celulares siendo Jurkat más sensible que K562, lo cual se corroboró con los ensayos de clonogenicidad. Este extracto también mostró un efecto de acumulación de células Sub-G1 dependiente de la dosis, el cual fue diferencial entre las dos líneas celulares. La duración del tratamiento con el extracto hexánico no fue significativa para las células K562 pero sí para la línea celular Jurkat. Además, el porcentaje de acumulación de las células Sub-G1 fue mayor para células K562 comparado con Jurkat. El extracto metanólico presentó un efecto antiproliferativo similar al hexánico, pero fue más potente con la menor concentración (10 µg/mL en la clonogenicidad de K562. El efecto sobre el ciclo celular, también fue similar al hexánico, pero la duración del tratamiento no fue significativa en la acumulación de células en Sub-G1. Conclusiones: los resultados muestran el potencial diferencial de los extractos sobre el ciclo celular de las líneas leucemoides evaluadas

  10. Origins of domestication and polyploidy in oca (Oxalis tuberosa : Oxalidaceae): nrDNA ITS data.

    Emshwiller, E; Doyle, J

    1998-07-01

    As part of a study aimed at elucidating the origins of the octoploid tuber crop "oca," Oxalis tuberosa, DNA sequences of the internal trancribed spacer of nuclear ribosomal DNA (nrDNA ITS) were determined for oca and several wild Oxalis species, mostly from Bolivia. Phylogenetic analysis of these data supports a group of these species as being close relatives of oca, in agreement with morphology and cytology, but at odds with traditional infrageneric taxonomy. Variation in ITS sequences within this group is quite low (0-7 substitutions in the entire ITS region), contrasting with the highly divergent (unalignable in some cases) sequences within the genus overall. Some groups of morphologically differentiated species were found to have identical sequences, notably a group that includes oca, wild populations of Oxalis that bear small tubers, and several other clearly distinct species. The presence of a second, minor sequence type in at least some oca accessions suggests a possible contribution from a second genome donor, also from within this same species group. ITS data lack sufficient variation to elucidate the origins of oca precisely, but have identified a pool of candidate species and so can be used as a tool to screen yet unsampled species for possible progenitors.

    Full Text Available Inflammation is the major causative factor of different diseases such as cardiovascular disease, diabetes, obesity, osteoporosis, rheumatoid arthritis, inflammatory bowel disease, and cancer. Anti-inflammatory drugs are often the first step of treatment in many of these diseases. The present study is aimed at evaluating the anti-inflammatory properties of isoorientin, a selective cyclooxygenase-2 (COX-2 inhibitor isolated from the tubers of Pueraria tuberosa, in vitro on mouse macrophage cell line (RAW 264.7 and in vivo on mouse paw edema and air pouch models of inflammation. Isoorientin reduced inflammation in RAW 264.7 cell line in vitro and carrageenan induced inflammatory animal model systems in vivo. Cellular infiltration into pouch tissue was reduced in isoorientin treated mice compared to carrageenan treated mice. Isoorientin treated RAW 264.7 cells and animals showed reduced expression of inflammatory proteins like COX-2, tumor necrosis factor-α (TNF-α, interleukin-6 (IL-6, 5-lipoxygenase (5-LOX, and interleukin 1-β (IL-1-β both in vitro and in vivo. The antioxidant enzyme levels of catalase and GST were markedly increased in isoorientin treated mice compared to carrageenan treated mice. These results suggest that isoorientin, a selective inhibitor of COX-2, not only exerts anti-inflammatory effects in LPS induced RAW cells and carrageenan induced inflammatory model systems but also exhibits potent antioxidant properties.

    Full Text Available El objetivo del presente artículo es el de describir las diferentes opciones de regímenes cambiarios para los mercados emergentes de América Latina; que van desde el tipo de cambio fijo, al flexible; con sus variantes como son la Caja de Conversión y la dolarización de la economía, en el contexto actual caracterizado por situaciones de persistente volatilidad de capital y crisis cambiaria. Se concluye que existen hoy más argumentos en contra de establecer durante mucho tiempo regímenes de tipo de cambio fijo, no solamente debido a las distorsiones y costos de la sobrevaluación de la moneda nacional, sino también por los costos que entraña su abandono, asimismo habría que sopesar los argumentos en contra de una excesiva flexibilidad que devendría en volatilidad del tipo de cambio; para ello cabe dar un espacio a que la autoridad pública intervenga, dando con su intervención una señal del tipo de cambio real que se considera conveniente, y reafirmar la importancia de desalentar los flujos de capitales externos especulativos. Se destaca con respecto a la proposición de la Caja de Conversión o de la Dolarización que son alternativas que privilegian la estabilidad monetaria, sacrificando otros objetivos macroeconómicos como el de la producción, el comercio, el empleo. Por lo cual es necesario actuar sobre determinantes fundamentales como son la disciplina fiscal, el avance en las reformas económicas; impulsando el progreso tecnológico que consiste en hacer más eficiente los procesos productivos a través de la inversión en tecnologías de punta.

    Full Text Available Las cajas de ahorros Españolas son posiblemente el caso más significativo a nivel mundial de entidades multistakeholders, no sólo por su misión, sino también en su gobernanza. La teoría multifiduciaria de los stakeholders plantea, al menos de forma teórica lo que en las cajas de ahorros ha sido una realidad por más de un siglo. Así, las cajas se convierten en un “caso de laboratorio” para analizar la viabilidad e idoneidad de una gobernanza participada por el conjunto de stakeholders de la organización. Nuestra hipótesis es que la gobernanza multistakeholder, así como la orientación hacia los stakeholders, generan un planteamiento estratégico diferente, no centrado en los beneficios. Por tanto, la gobernanza multifiduciaria puede perfectamente ser más ineficiente en relación con indicadores económico-financieros referidos a los shareholders de una entidad. Sin embargo, estas entidades deberían ser más eficientes si se tienen en cuenta indicadores relacionados con la generación de valor social. Con el fin de contrastar la eficiencia relativa hemos utilizando la población de bancos y cajas de España y los datos de 2009, utilizando la técnica de Análisis Envolvente de Datos con objeto de comparar la eficiencia económica, social y global de ambos tipos de entidades. Los resultados indican una diferenciación significativa entre estos dos grupos de entidades financieras en relación con la eficiencia social y económica, si bien no ocurre lo mismo cuando se utiliza la eficiencia global –económica más social-. Por lo que podemos concluir que la eficiencia en la gestión entre inputs y outputs en cajas de ahorros y bancos es similar. / Probably, Spanish savings banks are the most significant worldwide multistakeholders entities, not only because of their mission, but also in their governance.

    Danilo E F L Flôres

    Full Text Available Subterranean rodents spend most of the day inside underground tunnels, where there is little daily change in environmental variables. Our observations of tuco-tucos (Ctenomys aff. knighti in a field enclosure indicated that these animals perceive the aboveground light-dark cycle by several bouts of light-exposure at irregular times during the light hours of the day. To assess whether such light-dark pattern acts as an entraining agent of the circadian clock, we first constructed in laboratory the Phase Response Curve for 1 h light-pulses (1000lux. Its shape is qualitatively similar to other curves reported in the literature and to our knowledge it is the first Phase Response Curve of a subterranean rodent. Computer simulations were performed with a non-linear limit-cycle oscillator subjected to a simple model of the light regimen experienced by tuco-tucos. Results showed that synchronization is achieved even by a simple regimen of a single daily light pulse scattered uniformly along the light hours of the day. Natural entrainment studies benefit from integrated laboratory, field and computational approaches.

    This article reports historical ethnobotany research conducted from a study of the work Historia Naturalis Brasiliae (Natural History of Brazil), authored by Piso and Marcgrave and published in 1648, with main focus on Caatinga of northeast region of Brazil. Focusing the content analysis on the section dedicated to plant species with multiple uses, Marcgrave's contribution to the aforementioned work, this research had the following objectives: the retrieval of 17th century knowledge about the food uses of the flora in the northeast region of Brazil, including the taxonomic classifications; the identification of plant parts, their modes of consumption and the ethnic group of consumers; and the verification of the use of these species over time. The use of 80 food species at the time of the publication of the work is indicated, some of which are endemic to the Caatinga, such as "umbu" (Spondias tuberosa Arruda), "mandacaru" (Cereus jamacaru DC.) and "carnauba" (Copernicia cerifera Mart.). It is noticeable that among the species listed by Marcgrave, some species still lack current studies indicating their real nutritional value. The present study is an unprecedented work because it introduces, in a systematic way, the food plants described in a study of 17th century Brazil. Finally, this study makes information about plants consumed in the past accessible, aiming to provide material for studies that could develop new food products today.

    Full Text Available El presente trabajo intenta mostrar los ajustados límites que los arreglos de tipo Currency Board tienen a la hora de actuar como prestamista de última instancia que, en caso de producirse una corrida bancaria, puede llevar a las autoridades monetarias de un país a la difícil elección entre sostener al sistema bancario vs. el arreglo cambiario elegido, fruto del incremento en la inestabilidad del propio sistema bancario. Esta situación persiste aún en casos como el argentino donde su Caja de Conversión, instaurada en Abril de 1991, mostraba límites más flexibles que versiones más ortodoxas, dados por la propia conformación del backing de su base monetaria. La situación antes comentada permite plantear una hipótesis objeto de análisis y verificación empírica: cómo afecta al sistema financiero (esto es, el incremento en la inestabilidad del mismo cuando se dota a la autoridad monetaria de un país de una capacidad limitada de emisión de dinero para cubrir el rol de prestamista de última instancia ante una crisis bancaria bajo un contexto de Caja de Conversión no ortodoxa.

    Full Text Available Un estudio de factibilidad técnico económico en cualquier rama de la ingeniería o en cualquier tipo de negocio, implica conocer una medida de la rentabilidad del emprendimiento. Actualmente, nadie discute que para una toma de decisión fundamentada se deben utilizar los métodos de flujo de caja descontados (DCF, a pesar de que persisten otras formas muy difundidas (por ejemplo: período de repago, relación beneficio/costo. El objetivo del trabajo es analizar críticamente los métodos a utilizar para evaluar proyectos mutuamente excluyentes, como también proponer formas alternativas de análisis de rentabilidad que contemplen la incidencia de las distintas tasas y acoten la decisión de un modo adecuado. La propuesta presentada aquí permite ordenar alternativas excluyentes con criterios que contengan una visión mas completa. El resultado más interesante está relacionado con la sensibilidad de los métodos sobre las variables de decisión inherentes a estos.Palabras clave: DCF, costo de capital; proyectos excluyentes; rentabilidad de proyectos.

    Full Text Available Polianthes tuberosa L. es una planta endémica de México, comercialmente se cultiva para flor de corte, y, además, es utilizada en la industria farmacéutica y del perfume. Tradicionalmente, los productores la propagan utilizando los cormos, lo que ha ocasionado que el cultivo presente poca variabilidad genética y posiblemente, por esta razón solo se conocen cultivares con flores blancas. Con base en lo anterior el objetivo de la presente investigación consistió en establecer la metodología práctica y competitiva para propagar in vitro Polianthes tuberosa L. Las yemas y pequeños segmentos de tejido de cormo fueron colocadas sobre la superficie del medio de cultivo, base GC (comunicación personal Guillermo Carrillo con las sales inorgánicas del medio de cultivo Murashige y Skoog (1962 por litro, 50 mL de agua de coco, 20 g de sacarosa, 6.4 g de agar y el pH fue ajustado a 5.7. Con este medio básico se prepararon medios de cultivo que contenían bencilaminopurina (BAP, ácido naftalenacético (ANA, ácido 2,4-diclorofenoxiacético (2,4-D, ácido indolacético (AIA, y cinetina. La formación de brotes que dieron origen a las plántulas ocurrió mediante, la regeneración directa de la yema floral la cual al crecer forma sólo una plántula y a partir del tejido de la base de la yema, de esta región se obtuvieron hasta seis brotes por yema en el medio que contiene BAP, 4.5 mg y ANA, 0.1 mg, del cual la regeneración de brotes fue mayor (56.1 %. En el caso de cormo el problema fue la contaminación llegando en algunos casos hasta el 100 % de los cultivos.

    Full Text Available The present study is inspired by the great wealth of species exhibited by the ichthiofauna. Not only concepts and techniques of ecology deserve attention, but also knowledge in other biological areas, such as zoology and anatomy, are necessary. The intention of the present work is to discover the morphology of fish through the study of the digestive tract morphology, associating it to diet data, in order to better understand the biology of four fish species of the upper Paraná River floodplain. The samples were collected quarterly in the year 2000 with gillnets of different meshes. The stomach content was analyzed under a stereoscopic microscope and the frequencies of occurrence (FO and volumetric (FV and the alimentary index (IAi were calculated. Various morphologic characteristics were analyzed and schematized using a light chamber. The species were grouped into two trophic guilds - insectivores (Astyanax altiparanae and Parauchenipterus galeatus and piscivores (Serrasalmus marginatus and Hoplias aff. malabaricus. The first two, although consumers of insects, preyed on different alimentary groups, notably Hymenoptera in the case of A. altiparanae and Coleoptera in the case of P. galeatus. Serrasalmus marginatus and H. aff. malabaricus consumed mainly fishes. However, only pieces of prey were usually found in the stomach content of the first species, whereas whole fishes were found in the stomach content of the second. Astyanax altiparanae exhibited characteristics that allowed it to obtain food in several compartments of the water column. Similarly P. galeatus consumed food resources that were available in all aquatic compartments, although the abilities to capture, to manipulate and to absorb food differed, as shown by the importance of teeth plates and pharyngeal teeth. Serrasalmus marginatus and H. aff. malabaricus, although resembling each other in many aspects of the digestive tract morphology, differed in the strategies used to capture

    Full Text Available Some species of the genus Anastrepha (Diptera: Tephritidae are successfully managed by matching the sterile insect technique with parasitoid releases. Such strategies used in integrated pest management can be implemented only where insect mass-rearing programs are feasible. In this study, we show the process of domestication, rearing technology and quality control data obtained from 54 generations of Anastrepha sp.1 aff. fraterculus (Wiedemann, 1830 kept under fully artificial conditions. Eggs were collected by an artificial oviposition panel consisting of one side of the cage made of blue voile fabric externally covered with a thin layer of silicon rubber. They were then air-bubbled in water at 25 ºC for 48 h before seeding. Larvae were reared on the regular laboratory artificial diet with 66 % of agar reduction turning over a semi-liquid diet, which reduced costs and improved insect quality. The adult and larval diets were composed of local ingredients including hydrolyzed yeast. When large-scale production of this fly is contemplated, the critical stage is larval development. This system of artificial rearing for A. fraterculus sp.1 developed in Brazil, allows for the production of a large number of insects of excellent quality using local ingredients and less agar in diet composition than the original medium used for this species. By reducing the interval of egg collection, the system might be optimized in terms of insect yield and, therefore, meet the demands of A. fraterculus sp.1 with regard to integrated pest management purposes.

    We report the first studies of characterization and extraction of the Pamphobeteus aff. nigricolor (Pocock, 1901) (Aranae:Theraphosidae) venom done in Colombia using the electro-stimulation technique previous anesthesia with isofluorane. After each extraction process, a low viscosity, colorless venom was obtained. This venom showed a 1.01 mg/μl density and a pH of 5. The humidity percentage did not show a significance difference between males and females (P > 0.05) with a general media of 77.49 ± 1.74%. In all cases the venom yielded was variable between males and females, with a media of 22.45 ± 5.17 mg (wet weight) and 4.58 ± 0.94 mg (dry weigh), obtaining larger amounts in females, 28.34 ± 7.49 mg and 5.69 ± 1.36 (wet and dry weight respectively). Venom showed a hemolytic activity dependent of enzymatic active phospholipase and neither coagulant nor proteolytic activities were observed. Electrophoretic profile showed a main protein content with a molecular mass below 14 kDa. RP-HPLC venom profile revealed a difference among male and female venom's content where 17 and 21 main fractions were obtained respectively. Three peptides, Theraphotoxin-Pn1a, Theraphotoxin-Pn1b and Theraphotoxin-Pn2a, were identified using HPLC-nESI-MS/MS. These peptides showed a high identity with other peptides found on Theraphosides which are proved to affect voltage-gated calcium channels. Copyright © 2013 Elsevier Ltd. All rights reserved.

    The aims of this research were to investigate if pulsed electric field (PEF) treatments caused cellular/structural alterations in Oxalis tuberosa (oca) tubers and if PEF treatment could reduce tuber oxalate levels. Whole oca tubers were treated with PEF at different electric field strengths up to 1.2 kV/cm. PEF treatments above 0.5 kV/cm caused tubers to soften, but differences in the electrical properties of the tuber tissues led to an uneven PEF effect with the tuber inner cores softening more than the middle regions. Cell viability tests confirmed the unevenness of the PEF effect, however PEF caused no changes in overall tuber/tissue structure. Even at high electric field strengths the cell remained largely intact and most starch grains were retained within the cells. Despite the retention of starch, PEF treatment reduced tuber oxalate contents by almost 50% in some tissues and could potentially aid the development of low oxalate oca-based foods.

    The Andean tuber-bearing species, Oxalis tuberosa Mol., is a vegetatively propagated crop cultivated in the uplands of the Andes. Its genetic diversity was investigated in the present study using the inter-simple sequence repeat (ISSR) technique. Thirty-two accessions originating from South America (Argentina, Bolivia, Chile, and Peru) and maintained in vitro were chosen to represent the ecogeographic diversity of its cultivation area. Twenty-two primers were tested and 9 were selected according to fingerprinting quality and reproducibility. Genetic diversity analysis was performed with 90 markers. Jaccard's genetic distance between accessions ranged from 0 to 0.49 with an average of 0.28 +/- 0.08 (mean +/- SD). Dendrogram (UPGMA (unweighted pair-group method with arithmetic averaging)) and factorial correspondence analysis (FCA) showed that the genetic structure was influenced by the collection site. The two most distant clusters contained all of the Peruvian accessions, one from Bolivia, none from Argentina or Chile. Analysis by country revealed that Peru presented the greatest genetic distances from the other countries and possessed the highest intra-country genetic distance (0.30 +/- 0.08). This suggests that the Peruvian oca accessions form a distinct genetic group. The relatively low level of genetic diversity in the oca species may be related to its predominating reproduction strategy, i.e., vegetative propagation. The extent and structure of the genetic diversity of the species detailed here should help the establishment of conservation strategies.

    Full Text Available Este trabalho teve como objetivo analisar alguns aspectos da alimentação de larvas de Bryconamericus aff. iheringii, capturadas nos meses de julho e novembro de 2001, nas regiões limnética e litorânea do reservatório de Santa Maria, rio Piquiri, Estado do Paraná. As larvas apresentaram boca subterminal durante todo o seu desenvolvimento. O tubo digestório se diferenciou em estômago e intestino apenas no estágio de pós-flexão. As larvas consumiram, principalmente, algas e microcrustáceos, o que permitiu caracterizá-las como planctófagas. A intensa modificação morfológica no trato digestório nos indivíduos em pós-flexão coincidiu com o aumento na abundância de algas em relação aos itens de origem animal; porém, de forma geral, a ocorrência aumentou para todos os itens. A análise do grau de digestão dos itens alimentares sugeriu que indivíduos em pré-flexão alimentaram-se, possivelmente, durante o dia, e os mais desenvolvidos, durante o entardecer e no período noturnoThe aim of this study was to analyze some feeding treats of Bryconamericus aff. iheringii larvae, sampled in both the limnetic and littoral regions of the Piquiri River, in Santa Maria reservoir, between July and November 2001. The larvae presented sub-terminal mouth in larval period. The digestive tract differentiated in terms of stomach and intestine only in the postflexion larvae. The larvae fed mainly on algae and microcrustacea allowing to characterize them as planktivorous. The intense morphologic shift in the digestive tract in the postflexion larvae coincided with an increase in the abundance of algae in relation to animals items; however, in general, all the items had their occurrence increased. Analysis of the digestion stage suggested that preflexion larvae, possibly, fed themselves during the day, and those more developed, at dusk and night

    Full Text Available We investigated the synergistic effect of three solutes (sodium chloride, sucrose, tricalcium phosphate in different combinations of concentration, on the moisture, solid gain and calcium gain in oca (Oxalis tuberosa with and without chitosan (CR and SR. In both cases applied the Simplex with Extended Centroid mixture design. Were used cylinders of oca of 0.9 cm of diameter and 3.4 cm of length. The kinetics of moisture, solid gain and calcium gain for 48 hours was evaluated. The effective diffusivity of water, solids and calcium was determined. We found that in samples CR is greater loss of water and less solid gain compared with SR samples mainly as sodium chloride or sucrose participate independently, while for the gain of calcium, in all cases, the CR samples gain more of calcium than SR samples. The effective diffusivities found are: water, 1.19E-09 m2 /s in samples CR and 1.34E-09 m2 /s in SR samples; for solid, 3.67E-09 m2 /s in samples CR and 5.43E-09 m2 /s in SR samples; and, for calcium 3.32E-11 m2 /s in samples CR and 1.57E-09 m2 /s in SR samples.

    Over the past two decades, a wealth of marine and terrestrial reptiles, including protorosaurian archosauromorphs, has been described from Triassic shales and limestone layers in southern China. Recovered from the eastern margin of the Tethys Ocean, these forms often show remarkable similarities to taxa that were previously known and described from Europe, i.e., the western Tethyan margin. One protorosaurian that is known from the western and the eastern Tethyan province is the genus Macrocnemus, with currently three recognized species: 1) M. bassanii from the Middle Triassic Besano Formation and Meride Limestone (late Anisian – early Ladinian), UNESCO World Heritage Site Monte San Giorgio, Ticino, Switzerland; 2) M. obristi from the Prosanto Formation (early Ladinian) of the Ducan area, Grisons, Switzerland; and 3) M. fuyuanensis from the Falang Formation (Ladinian), Yunnan Province, southern China. Recently a new specimen, PIMUZ T 1559, from the upper Besano Formation at Meride, Ticino, Switzerland, was prepared, revealing a disarticulated skeleton which includes most of the cranium and lower jaw, pre-caudal vertebral column and ribs, the forelimbs, and girdle elements. Unambiguously assignable to the genus Macrocnemus, it evinces particularly gracile elongated cervical ribs, as well as a humerus/radius ratio that is comparable only to that of M. fuyuanensis from southern China. Based on this feature we tentatively recognize the new specimen as M. aff. fuyuanensis from Europe. The position and exquisite preservation of the clavicle and interclavicle in this specimen allows a revision of the shoulder girdle of Macrocnemus when articulated, which also has implications for closely related protorosaurian taxa, such as the long-necked Tanystropheus. Furthermore, differences in the shape and morphology of the interclavicle including pointed wing-like lateral processes and a short, fusiform caudal process represent rare discrete characters that allow separation of the

    Microbial oils have been analyzed as alternatives to petroleum. However, just a handful of microbes have been successfully adapted to produce chemicals that can compete with their petroleum counterparts. One of the reasons behind the low success rate is the overall economic inefficiency of valorizing a single product. This study presents a lab-scale analysis of two yeast species that simultaneously produce multiple high-value bioproducts: intracellular triacylglycerols (TG) and extracellular polyol esters of fatty acids (PEFA), two lipid classes with immediate applications in the biofuels and surfactant industries. At harvest, the yeast strain Rhodotorula aff. paludigena UCDFST 81-84 secreted 20.9 ± 0.2 g L -1 PEFA and produced 8.8 ± 1.0 g L -1 TG, while the yeast strain Rhodotorula babjevae UCDFST 04-877 secreted 11.2 ± 1.6 g L -1 PEFA and 18.5 ± 1.7 g L -1 TG. The overall glucose conversion was 0.24 and 0.22 g (total lipid) g (glucose) -1 , respectively. The results present a stable and scalable microbial growth platform yielding multiple co-products.

    A monitoring program of the occupational exposure by incorporation of radioactive material is proposed. Nuclear medicine services of the Caja Costarricense del Seguro Social (CCSS) are evaluated. The monitoring program is based on the provisions of the International Atomic Energy Agency and of study of nuclear medicine services of the CCSS. Radionuclides are determined for monitoring of the occupational exposure, according to the radioactive material that is worked in nuclear medicine services of the CCSS. The appropriate and alternative techniques are established for the monitoring of the occupational exposure by incorporation of radioactive material, depending on the type of radionuclide that is worked in nuclear medicine services. The worker occupationally exposed (TOE) should be subject of monitoring and how often should be realized the monitoring of the occupational exposure. The monitoring of the radiation by radioactive material must be applied to personnel working in radiopharmacies and the worker has carried out therapeutic procedures for handling of significant amounts of 13 1 I. The calculation of the committed effective dose is proposed by incorporation of radioactive material with the TOE [es

    Full Text Available In the south of Brazil, one of the major limitations to milk production is the low forage availability during autumn and early winter. The use of dual-purpose wheat genotypes is one alternative to minimize the impact of low forage availability in addition to produce grains. Therefore, this study aimed to evaluate the nutritional value of two dual-purpose wheat genotypes (BRS Tarumã and BRS Umbu. Structural composition and forage nitrogen uptake were evaluated. The nutritional value of the forage was analyzed for mineral matter (MM, organic matter (OM, neutral detergent fiber (NDF, crude protein (CP, total digestible nutrients (TDN, in situ organic matter digestibility (ISOMD and in situ dry matter digestibility (ISDMD. Differences in NDF (49.03 vs. 46.44%, CP (24.4 vs. 27.4%, ISOMD (83.53 vs. 85.45%, ISDMD (83.59 vs. 86.65% and TDN (75.37 vs. 78.39 for BRS Umbu and BRS Tarumã genotypes were detected, respectively. The BRS Umbu genotype had a lower leaf blade proportion and forage nitrogen uptake. The dual-purpose wheat genotype BRS Tarumã was superior in nutritive value.

    Full Text Available Here we examine major anatomical characteristics of Corydoras aff. paleatus (Jenyns, 1842 post-hatching development, in parallel with its neurobehavioral evolution. Eleutheroembryonic phase, 4.3-8.8 days post-fertilization (dpf; 4.3-6.4 mm standard length (SL encompasses from hatching to transition to exogenous feeding. Protopterygiolarval phase (8.9-10.9 dpf; 6.5-6.7 mm SL goes from feeding transition to the commencement of unpaired fin differentiation, which marks the start of pterygiolarval phase (11-33 dpf; 6.8-10.7 mm SL defined by appearance of lepidotrichia in the dorsal part of the median finfold. This phase ends with the full detachment and differentiation of unpaired fins, events signaling the commencement of the juvenile period (34-60 dpf; 10.8-18.0 mm SL. Eleutheroembryonic phase focuses on hiding and differentiation of mechanosensory, chemosensory and central neural systems, crucial for supplying the larval period with efficient escape and nutrient detection-capture neurocircuits. Protopterygiolarval priorities include visual development and respiratory, digestive and hydrodynamic efficiencies. Pterygiolarval priorities change towards higher swimming efficacy, including carangiform and vertical swimming, necessary for the high social interaction typical of this species. At the end of the protopterygiolarval phase, simple resting and foraging aggregations are seen. Resting and foraging shoals grow in complexity and participant number during pterygiolarval phase, but particularly during juvenile period.

    Full Text Available Resumen: En el presente artículo se expone el diseño y validación de dos modelos de Estimulación Eléctrica Neuromuscular (E.E.N.M. para la relación entre parámetros de estimulación y características biomecánicas, siendo cada uno de ellos representativo de dos enfoques diferentes. Uno de ellos fisiológico simplificado, mientras que el otro es un modelo de caja negra basado en red neuronal, por lo que no incluye información sobre las características internas del sistema. En este artículo se exponen las características de cada uno, se describe el equipamiento utilizado y los experimentos para su identificación. Ambos modelos han sido identificados y validados en cinco sujetos sanos. El modelo fisiológico, a pesar de numerosas limitaciones encontradas, ha permitido el estudio en profundidad de los procesos internos y de la multitud de factores que involucran la activación muscular. El modelo en red neuronal, en cambio, presenta una buena precisión pero no proporciona conocimiento sobre los aspectos internos del sistema. Por ello, para una aplicación de control en la que sólo interesen las entradas y salidas del sistema, el modelo de caja negra es la mejor opción. Por otro lado, si se desea tener acceso a las variables internas del sistema neuromuscular bajo E.EN.M., es necesario realizar un análisis exhaustivo para la posterior mejora de las prestaciones del modelo fisiológico aquí presentado. Abstract: In this paper, a comparison and validation of two models of Neuromuscular Electrical Stimulation (NMES for the relationship between stimulation parameters and biomechanical characteristics is presented. Each model is representative of two opposite approaches: the first one is a physiological simplified model, while the second is a black-box model based on neural network, without information about the internal processes of muscle contraction under NMES.

    Full Text Available This study assessed the coexistence of three species of thraira present in the Upper Paraná River floodplain, using population structure as an investigation tool. The species were designated as: Hoplias sp. 1, introduced after the construction of the Itaipu reservoir, and Hoplias sp. 2 and Hoplias sp. 3, native species that have been identified as Hoplias aff. malabaricus. We tested the hypothesis that those species in fact differ from each other in respect of population abundance, sex ratio, relative frequency of adults and juveniles, length structure and weight-length relationship. Additionally, possible effects of the flood pulse on the first four of these parameters were investigated. Samples were collected quarterly from March 2006 to December 2007 from nine collection sites on the floodplain. Hoplias sp. 1 presented a greater balance of sex ratio and length structures over the seasons, as well as a higher allometric coefficient. The population attributes of Hoplias sp. 2 and Hoplias sp. 3 showed a high responsiveness to hydrological seasonality, indicating that these species exploit available resources in a conspicuous flood period with greater efficiency. These differences, beyond reflecting possible mechanisms that allow closely related species to coexist, indicate the importance of understanding the life strategies adopted by each species which, as part of a complex system, are considered key elements of the aquatic community structure in the region, providing important information for habitat management and biodiversity conservation.

    Capillary blocking caused by CO2 bubbles in anode flow field (AFF) is one of the bottlenecks for performance improvement of a micro direct methanol fuel cell (μDMFC). In this work, we present a novel AFF structure with nested layout of hydrophilic fuel channels and superhydrophobic degassing channels which can remove most of CO2 from AFF before it is released to the fuel channels. The new AFFs are fabricated on Ti substrates by using micro photochemical etching combined with anodization and fluorination treatments. Performance of the μDMFCs with and without superhydrophobic degassing channels in their AFF is comparatively studied. Results show that the superhydrophobic degassing channels can significantly speed up the exhaust of CO2 from the AFF. CO2 clogging is not observed in the new AFFs even when their comparison AFFs have been seriously blocked by CO2 slugs under the same operating conditions. 55% and 60% of total CO2 produced in μDMFCs with N-serpentine and N-spiral AFF can be respectively removed by the superhydrophobic degassing channels. The power densities of the μDMFCs equipped with new serpentine and spiral AFFs are respectively improved by 30% and 90% compared with those using conventional AFFs. This means that the new AFFs developed in this work can effectively prevent CO2-induced capillary blocking in the fuel channels, and finally significantly improve the performance of the μDMFCs.

    Full Text Available Microdontine syrphid flies are obligate social parasites of ants. Larvae prey on ant brood whereas adults live outside the nests. Knowledge of their interaction with their host is often scarce, as it is information about their natural enemies. Here we report the first case of parasitism of a species of microdontine fly by a myrmecophilous eurytomid wasp. This is also the first host record for Camponotophilus delvarei Gates, a recently described parasitic wasp discovered in Chiapas, Mexico, within the nests of the weaver ant, Camponotus sp. aff. textor Forel. Eleven pupal cases of a microdontine fly were found within a single nest of this ant, five of them being parasitized. Five adult C. delvarei females were reared from a puparium and 29 female and 2 male pupae were obtained from another one. The eurytomid is a gregarious, primary ectoparasitoid of larvae and pupae of Microdontinae, its immature stages developing within the protective puparium of the fly. The species is synovigenic. Adult females likely locate and parasitize their hosts within the ant nest. As some species of Microdontinae are considered endangered, their parasitoids are likewise threatened and in need of accurate and urgent surveys in the future.

The tubers were obtained from a local grocery. The morphology of the starch granules (size and shape was studied with scanning electron microscopy (SEM, which revealed ellipsoid, oval, conical, pear-shaped and prismatic forms: ellipsoids and oval granules with lengths up to 54.30 µm in oca; with lengths up to 32.09 µm for olluco starch granules; and with predominantly truncated spherical or oval forms and smaller dimensions (up to 16.29 um for mashua starch granules. Amylose contents were similar among the samples: 27.60% (oca, 26.49% (olluco and 27.44% (mashua. Olluco starch had less swelling power, forming opaque, less firm gels. All three starch gels showed the same stability on refrigeration and presented high syneresis under freezing temperatures, with a variation of 40.28 to 74.42% for olluco starch. The starches cooked easily, with high peak viscosity. The low gelatinization temperatures and high stability during cooling make these starches suitable feedstock for use in formulations that require milder processing temperatures and dispense freezing storage.

    Atypical femoral fractures (AFFs) have been reported to occur with minimal or spontaneous subtrochanteric and femoral shaft fractures with a characteristic transverse pattern, compared with typical femoral fractures in young patients with high-energy trauma. AFFs are related to long-term use of bisphosphonates (BPs), glucocorticoids and rheumatic diseases. We have estimated a blind analysis of AFFs in rheumatic patients receiving BPs and glucocorticoids ordinary over a long time in all Yamagata prefectural area through radiographic examination. The 123 AFFs including suspected cases over six years were collected and reviewed by two independent orthopedic surgeons. We found 86 patients with a total of 99 AFFs between 2009 and 2014 (1.43 cases/100,000 person/year). Of these 99 AFFs, 11 were in 8 rheumatic patients including three patients with bilateral AFFs. The incidence of AFFs in rheumatic patients had trend to increase from 2012. The mean age of all 8 patients was 54.9 years. All 8 patients received BPs and 7/8 received prednisolone (PSL). The mean dose of PSL was 14 mg/day. Compared to patients with unilateral AFFs, those with bilateral AFFs in rheumatic patients were on a higher dose of PSL (20 mg/day vs. 7 mg/day) and had less femoral neck-shaft angle (129° vs. 136°, p rheumatic patients showed a trend to increase from 2012 to 2014 in Yamagata prefecture. Careful management of AFFs is of particular importance in rheumatic patients who have taken high doses of PSL and have small femoral neck-shaft angle.

    Oxalis tuberosa is an important crop cultivated in the highest Andean zones. A germplasm collection is maintained ex situ by CIP, which has developed a morphological markers system to classify the accessions into morphotypes, i.e. groups of morphologically identical accessions. However, their genetic uniformity is currently unknown. The ISSR technique was used in two experiments to determine the relationships between both morphological and molecular markers systems. The intra-morphotype genetic diversity, the spatial structures of the diversity and the congruence between both markers systems were determined. In the first experience, 44 accessions representing five morphotypes, clearly distinct from each other, were analyzed. At the molecular level, the accessions exactly clustered according to their morphotypes. However, a genetic variability was observed inside each morphotype. In the second experiment, 34 accessions gradually differing from each other on morphological base were analyzed. The morphological clustering showed no geographical structure. On the opposite, the molecular analysis showed that the genetic structure was slightly related to the collection site. The correlation between both markers systems was weak but significant. The lack of perfect congruence between morphological and molecular data suggests that the morphological system may be useful for the morphotypes management but is not appropriate to study the genetic structure of the oca. The spatial structure of the genetic diversity can be related to the evolution of the species and the discordance between the morphological and molecular structures may result from similar selection pressures at different places leading to similar forms with a different genetic background.

    The purpose of mammography has been to provide the contrast between the lesion and adjacent healthy tissue of the breast. The quality control which should be performed in mammography services is essential to obtain the necessary contrast in mammography and thus achieve a prompt detection of breast lesions. The quality control program has helped to obtain exact diagnosis in mammography and has contributed to reduce mortality from breast cancer in Costa Rica. The Caja Costarricense de Seguro Social (CCSS) has sought to improve the quality of mammograms performed in the different health centers by implementing quality control programs in the services. The evaluation of the physical parameters has had as aim to perform an assessment of the equipment used in mammography facilities. The image quality, dosimetry, optical density, performance, accuracy and repeatability of voltage applied to the tube, filtration and Half-value layer in system of screen film mammography have been evaluated. The usefulness of quality control programs and needs of the services to implement a pilot plan for breast screening, can be seen when comparing the obtained results. The protocol of Mammography Quality Control, TECDOC 1517 from the International Atomic Energy Agency (IAEA), is implemented with this project and the associated software in four of the six hospitals evaluated in this study.

    Full Text Available Geológicamente la cuenca del río Yavi atraviesa por un período erosivo, que afecta especialmente las márgenes de los ríos provocando la formación de cárcavas y barrancos profundos. El área donde el río Cajas vuelca sus aguas al río Yavi es fértil en restos arqueológicos, el sitio más conocido es el Antigal de Yavi Chico, pero también se encuentran otros sitios menores, unos con arte rupestre y otros con hallazgos de artefactos líticos, y otros con restos cerámicos y óseos. Este sector de la cuenca está afectado por los procesos erosivos, es así que luego de los frecuentes derrumbes es posible ver los restos culturales en las escarpas expuestas. Se localizaron tres enterratorios: en urna, en el sitio denominado La Palca; otro en el antigal de Yavi Chico, y un tercero en Portillo. El análisis desde la antropología biológica, de restos humanos provenientes de sitios arqueológicos, aporta información importante acerca de las poblaciones que los habitaron, el estado sanitario en general, la alimentación, patologías, edad y sexo. De los análisis surge: una elevada incidencia de desgaste dental que afecta por igual a ambos sexos provocado probablemente por el tipo de alimentación, también se observan perdidas de piezas e indicios de periodontitis y en uno de los conjuntos óseos se advierte señas dejadas por enfermedades óseas (osteofitosis, deformación del esternón. Se espera poder contar en el futuro con una muestra más abundante para poder delinear de esta forma un panorama acerca de la salud de los pueblos prehispánicos de este sector de nuestra Puna.

    Atypical femoral fractures (AFFs) are stress-related fractures that are speculated to associate with long-term treatment with bisphosphonates for osteoporosis. A history of AFF is a high risk factor for the development of a subsequent AFF in the same location of the contralateral femur, suggesting that a patient's individual anatomical factor(s) are related to the fracture site of AFFs. In this study, we investigated the radiographs of fourteen AFFs (four bilateral fractures among ten patients) treated at six hospitals associated with our university between 2005 and 2010. The fracture site and standing femorotibial angle (FTA), which reflects the mechanical axis of the lower limb, were measured on weight-bearing lower limb radiographs. The fracture site and FTA of patients with typical femoral fractures (TFF) were compared to those of patients with AFFs. The correlations were examined using Spearman's rank correlation coefficients. The fracture locations in the femora were almost the same in the patients with bilateral AFFs. There was a positive correlation between the fracture site and the standing FTA in the patients with AFFs (r=0.82, 95% confidence interval; 0.49 to 0.94), indicating that the larger the standing FTA (varus alignment), the more distal the site of the fracture in the femur. The FTA of the patients with atypical diaphyseal femoral fracture were significantly larger compared to that of those with not only atypical subtrochanteric fractures but also TFFs. In conclusion, the fracture sites of AFFs are associated with the standing lower limb alignment, while those of TFFs are not. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available Inulin-type fructans are the most studied prebiotic compounds because of their broad range of health benefits. In particular, plants of the Agave genus are rich in fructans. Agave-derived fructans have a branched structure with both β-(2→1 and β-(2→6 linked fructosyl chains attached to the sucrose start unit with a degree of polymerization (DP of up to 80 fructose units. The objective of this work was to assess the prebiotic potential of three Agave angustifolia Haw fructan fractions (AFF with different degrees of polymerization. The three fructan fractions were extracted from the agave stem by lixiviation and then purified by ultrafiltration and ion exchange chromatography: AFF1, AFF2 and AFF3 with high (3–60 fructose units, medium (2–40 and low (2–22 DP, respectively. The fructan profile was determined with high-performance anion exchange chromatography with pulsed amperometric detection (HPAEC-PAD, which confirmed a branched fructan structure. Structural elucidation was performed by Fourier Transform Infra-Red Spectroscopy. The AFF spectrum shows characteristic fructan bands. The prebiotic effect of these fractions was assessed in vitro through fermentation by Bifidobacterium and Lactobacillus strains. Four growth patterns were observed. Some bacteria did not grow with any of the AFF, while other strains grew with only AFF3. Some bacteria grew according to the molecular weight of the AFF and some grew indistinctly with the three fructan fractions.

  12. Field and laboratory studies provide insights into the meaning of day-time activity in a subterranean rodent (Ctenomys aff. knighti, the tuco-tuco.

    Directory of Open Access Journals (Sweden)

    Barbara M Tomotani

    Full Text Available South American subterranean rodents (Ctenomys aff. knighti, commonly known as tuco-tucos, display nocturnal, wheel-running behavior under light-dark (LD conditions, and free-running periods >24 h in constant darkness (DD. However, several reports in the field suggested that a substantial amount of activity occurs during daylight hours, leading us to question whether circadian entrainment in the laboratory accurately reflects behavior in natural conditions. We compared circadian patterns of locomotor activity in DD of animals previously entrained to full laboratory LD cycles (LD12:12 with those of animals that were trapped directly from the field. In both cases, activity onsets in DD immediately reflected the previous dark onset or sundown. Furthermore, freerunning periods upon release into DD were close to 24 h indicating aftereffects of prior entrainment, similarly in both conditions. No difference was detected in the phase of activity measured with and without access to a running wheel. However, when individuals were observed continuously during daylight hours in a semi-natural enclosure, they emerged above-ground on a daily basis. These day-time activities consisted of foraging and burrow maintenance, suggesting that the designation of this species as nocturnal might be inaccurate in the field. Our study of a solitary subterranean species suggests that the circadian clock is entrained similarly under field and laboratory conditions and that day-time activity expressed only in the field is required for foraging and may not be time-dictated by the circadian pacemaker.

    Full Text Available ABSTRACT We describe and compare the histology of liver and spleen ofGeophagus brasiliensis (Perciformes, Hypostomus francisci (Siluriformes and Hoplias aff. malabaricus (Characiformes, tropical freshwater fishes. InG. brasiliensisandH. aff. malabaricusthe hepatocytes were arranged in tubular form whereas in H. franciscithey cord-like. In all species, hepatocytes presented glycogen, but in G. brasiliensis and H. aff. malabaricus they showed strong stained for hemossiderin in the cytoplasm. InG. brasiliensis and H. aff. malabaricus, melanomacrophage centres (MMCs were associated to hepatic structures and only in G. brasiliensis was observed intrahepatic exocrine pancreas. The spleen, in all species, was characterized by red and white pulp without boundary between the two regions, but only in H. francisci was recorded nodular organization in splenic parenchyma. The G. brasiliensisandH. aff. malabaricuspresented in the white pulp MMCs linked mainly to ellipsoids. Besides, we observed large MMCs in the spleen in relation to liver of G. brasiliensis and H. aff. malabaricus. In liver, highest values of reticular fibers and collagen were observed inG. brasiliensis. In spleen, highest values of reticular fibers and collagen were recorded inH. aff. malabaricusandH. francisci, respectively. Histological differences confirm the hypothesis that the phylogenetic distance is reflected in liver and spleen.

  15. Rhythmic 24 h variation of core body temperature and locomotor activity in a subterranean rodent (Ctenomys aff. knighti, the tuco-tuco.

    Directory of Open Access Journals (Sweden)

    Patricia Tachinardi

    Full Text Available The tuco-tuco Ctenomys aff. knighti is a subterranean rodent which inhabits a semi-arid area in Northwestern Argentina. Although they live in underground burrows where environmental cycles are attenuated, they display robust, 24 h locomotor activity rhythms that are synchronized by light/dark cycles, both in laboratory and field conditions. The underground environment also poses energetic challenges (e.g. high-energy demands of digging, hypoxia, high humidity, low food availability that have motivated thermoregulation studies in several subterranean rodent species. By using chronobiological protocols, the present work aims to contribute towards these studies by exploring day-night variations of thermoregulatory functions in tuco-tucos, starting with body temperature and its temporal relationship to locomotor activity. Animals showed daily, 24 h body temperature rhythms that persisted even in constant darkness and temperature, synchronizing to a daily light/dark cycle, with highest values occurring during darkness hours. The range of oscillation of body temperature was slightly lower than those reported for similar-sized and dark-active rodents. Most rhythmic parameters, such as period and phase, did not change upon removal of the running wheel. Body temperature and locomotor activity rhythms were robustly associated in time. The former persisted even after removal of the acute effects of intense activity on body temperature by a statistical method. Finally, regression gradients between body temperature and activity were higher in the beginning of the night, suggesting day-night variation in thermal conductance and heat production. Consideration of these day-night variations in thermoregulatory processes is beneficial for further studies on thermoregulation and energetics of subterranean rodents.

    Full Text Available Para evaluar los efectos del estrés agudo sobre la recuperación y la extinción de la memoria espacial, se utilizaron ratas entrenadas en el laberinto circular de Barnes. El entrenamiento consistió de 8 ensayos de adquisición (intervalo entre ensayos, IEE, de 5 min en donde los animales debían aprender a encontrar una caja meta ubicada en uno de los 18 agujeros del laberinto. Todos los animales adquirieron el aprendizaje espacial, ya que invirtieron menos tiempo en encontrar la caja meta y cometieron menos errores a medida que se sucedían los ensayos de entrenamiento. Veinticuatro horas después del entrenamiento se evaluó la retención y extinción del aprendizaje espacial mediante una prueba con caja meta (PCC seguida de siete pruebas sin caja (PSC, con un IEE de 5 min. Una hora y media antes de la sesión de evaluación de la memoria un grupo de animales fue sometido a estrés por restricción de movimientos durante una hora, permitiéndoles un período de recuperación de 30 min y otro grupo permaneció en su caja hogar sin manipulación (control. Los resultados indican que el estrés deteriora el proceso de evocación de la memoria espacial, ya que los animales estresados cometieron un mayor número de errores y demoraron más tiempo en encontrar la caja meta durante la PCC, respecto de los controles. Además, el estrés facilita el proceso de extinción, ya que, durante las PSCs los animales estresados no mostraron una persistencia en la exploración del agujero que, en el entrenamiento, conducía a la caja meta.

    Sterile mass-reared Mexican fruit flies, Anastrepha ludens (Loew), were trapped in a citrus orchard by using multilure traps and cylindrical sticky traps baited with Advanced Pheromone Technologies Anastrepha fruit fly (AFF) lures or Suterra BioLure two-component (ammonium acetate and putrescine) MFF lures (BioLures). The cylinder trap/AFF lure combination was the best trap over the first 6 wk, the multilure trap/BioLure combination was best during weeks 6-12, and the multilure trap/AFF lure combination was best during the last 6 wk. The multilure trap/BioLure combination was best overall by 36% over the cylinder trap/AFF lure combination, and 57% over the multilure trap/AFF lure combination. Cylinder traps with BioLures were the least effective trap/lure combination throughout the experiment, capturing only half as many flies as cylinder traps with AFF lures. Captures with cylinder traps baited with either lure and multilure traps with BioLures were female biased. For the most part, both lures remained highly attractive and emitted detectable amounts of attractive components under hot field conditions for the duration of the 18-wk experiment. Total emission of ammonia was 4 times greater and 1-pyrroline at least 10 times greater from AFF lures compared with BioLures. Correlations of trap and lure performance with ammonia emission and weather were determined, but no conclusions were possible. Results indicate that BioLures would be the lure of choice in multilure or other McPhail-type traps and AFF lures would be superior with most sticky traps or kill stations that attract flies to outer (not enclosed) surfaces.

  3. Gametogenesis and reproductive cycle of Melanorivulus aff. punctatus (Boulenger, 1895 (Cyprinodontiformes, Rivulidae in Chapada dos Guimarães, Mato Grosso, Brazil

    Monica Cassel

    Full Text Available The comprehension of the reproductive cycle allows to understand which are the morphological changes that develop in the gonad during this interval. Thus, many studies have been undertaken in order to describe and classify the stages of gonadal development and reproductive status of Neotropical fishes. For this purpose, specimens of Melanorivulus aff. punctatus were collected in a permanent dam in Chapada dos Guimarães, Mato Grosso, Brazil. The gonads were prepared for analysis by light microscopy. The oogenesis and spermatogenesis have been described, characterizing the stages of gonadal development, together with assessments of the gonadosomatic ratio, germ cell count and verification of variation of mature oocytes in females. Throughout the year the male gonads presented themselves as capable of reproducing, characterized by the presence of undifferentiated and differentiated spermatogonia, spermatocytes organized into cysts, spermatids in cysts whose wall was thicker and the spermatozoa was free in the lumen and the duct. This can indicate a continuous reproductive cycle with split spermiation. The females had gonads in the development stage from May to September with undifferentiated and differentiated oogonias and early oocytes always facing the lumen, abundant pre-vitellogenic and vitellogenic oocytes and some atresias. In the phase capable of spawning, observed from October to March, the mature oocytes are abundant, there are many post-ovulatory complexes and some atresia in advanced stage. The regression, observed in some individuals from February to April, is characterized by ovaries with many atresias and post-ovulatory complexes. The same results were found in the quantitative assessments. Therefore, it may be characterized as discontinuous cycle with split spawning. Thus, the reproductive cycle of this species can be characterized as continuous for males and discontinuous for females, which have a most intense phase of reproduction

    Feral Mexican fruit flies, Anastrepha ludens (Loew) (Diptera: Tephritidae), were trapped in a citrus orchard in Mexico by using two types of synthetic food-odor lures, the AFF lure (Anastrepha fruit fly lure, APTIV, Inc., Portland, OR) and the BioLure (two-component MFF lure, Suterra LLC, Inc., Bend, OR). In Multilure traps (Better World Manufacturing, Inc., Miami, FL) containing water, BioLures captured about the same numbers of flies as AFF lures. In Multilure traps containing antifreeze solution, BioLures captured 2 and 5 times more flies than AFF lures in two experiments. BioLures, and AFF lures did not differ in attractiveness when used on sticky traps (Intercept trap, APTIV, Inc.; and sticky cylinder trap). Multilure traps captured >4 times as many flies as sticky traps with the exception that captures of females did not differ between Multilure and sticky traps baited with AFF lures. The percentage of females captured in Multilure traps was greater when traps were baited with BioLures compared with AFF lures, but the reverse was true for sticky traps. Sticky cylinder traps captured a higher percentage of females than Multilure traps. The most effective trap/lure combination was the Multilure trap baited with BioLure and antifreeze. In comparison with tests of these two lures in Texas, results were similar for Multilure traps, but they differed for sticky cylinder traps in that AFF lures were consistently more attractive than BioLures in Texas, but not in Mexico.

    Full Text Available Myrmecophyte is a common medicinal plant used by local people in Indonesia for treating various diseases especially in Papua. Bengkulu province is one of the Myrmecophyte habitats, but there has no report on its identity and distribution. The objectives of this research were to identify the diversity and analyze the Myrmecophytes distribution as well as factor affecting its presence. This study used purposive sampling method by exploring the area where Myrmecophytes commonly found. The Myrmecophyte distribution based on host tree was analyzed using Morishita index and the autecological analysis of abiotic factors was performed using Principal Component Analysis (PCA generated from Minitab 16. The results of this research showed that there were two species of Myrmecophytes in Bengkulu province, namely Hydnophytum formicarum and Myrmecodia tuberosa, as well as two variants of M. tuberosa i.e. M. tuberosa ‘armata’ and M. tuberosa ‘siberutensis’. The distribution of Myrmecophytes based on host tree was mostly randomly scattered in Central Bengkulu regency, Seluma, North Bengkulu, South Bengkulu, and Kaur. Their distributions were affected by light intensity and temperature. The data of this research can be used as basic information for carried out conservation efforts in Bengkulu province. The abundance of Myrmecophytes is also used as a source of additional income for local people in Bengkulu province.

    Most tropical lianas have specialized organs of attachment such as twining stems, hooks or tendrils but some do not. Many climbers also have an early self-supporting phase of growth and in some species this can produce treelet-sized individuals. This study focuses on how a liana can climb without specialized attachment organs and how biomechanical properties of the stem are modulated between self-supporting treelets and canopy-climbing lianas. Biomechanics and stem development were investigated in self-supporting to climbing individuals of Manihot aff. quinquepartita (Euphorbiaceae) from tropical rain forest at Saül, central French Guiana. Bending tests were carried out close to the site of growth. Mechanical properties, including Young's elastic modulus, were observed with reference to habit type and changes in stem anatomy during development. This liana species can show a remarkably long phase of self-supporting growth as treelets with stiff, juvenile wood characterizing the branches and main stem. During the early phase of climbing, stiff but unstable stem segments are loosely held in a vertical position to host plants via petiole bases. The stiffest stems--those having the highest values of Young's modulus measured in bending--belonged to young, leaning and climbing stems. Only when climbing stems are securely anchored into the surrounding vegetation by a system of wide-angled branches, does the plant develop highly flexible stem properties. As in many specialized lianas, the change in stiffness is linked to the development of wood with numerous large vessels and thin-walled fibres. Some angiosperms can develop highly effective climbing behaviour and specialized flexible stems without highly specialized organs of attachment. This is linked to a high degree of developmental plasticity in early stages of growth. Young individuals in either open or closed marginal forest conditions can grow as substantial treelets or as leaning/climbing plants, depending on the

Hacen parte de los tumores cardiacos primarios, los cuales son poco frecuentes, con una incidencia que varía entre 0,0017% y 0,28%. El más frecuente de los tumores cardiacos primarios es el rabdomioma. Se describe asociación con esclerosis tuberosa hasta en 72% de los casos, razón por la cual ésta debe buscarse ante el hallazgo de rabdomioma cardiaco.Cardiac rhabdomyomas are benign tumors derived from cardiac muscle fibers. They are usually multiple, but tend to decrease both in number and size with growth, with spontaneous regression in 90% of cases. These lesions are part of the primary cardiac tumors, which are uncommon, and have a variable incidence between 0.0017 and 0.28%. The most common primary cardiac tumor is the rhabdomyoma. An association between rhabdomyoma and tuberous sclerosis has been described in up to 72% of cases. For this reason, a patient with cardiac rhabdomyoma should be investigated for tuberous sclerosis.

    There still remains controversy on the pathomechanism of atypical femoral fracture (AFF). The angle of lateral bowing and bone mineral density showed significant differences between subtrochanteric and diaphyseal atypical fracture groups. In addition to the use of bisphosphonate, mechanical factors might play important roles in the occurrence of AFFs. Although AFF could be divided into subtrochanteric and diaphyseal fracture according to the location of fractures, there is a lack of evidence regarding differences between two fractures and etiology of the occurrence. The aim of study is to determine differences between atypical subtrochanteric and diaphyseal fracture in Korean population. Between February 2010 and March 2015, 51 AFFs in 40 patients were included in this study. Their medical records were retrospectively reviewed. The AFF patients satisfied all the diagnostic criteria of the 2014 revised edition of the ASMBR. To analyze the differences according to the location of fracture, the AFFs were divided into subtrochanteric (n = 16) and diaphyseal (n = 35) fracture groups. The following factors were compared between two groups: patients' demographics, underlying diseases, laboratory findings (serum-25(OH) VitD3, osteocalcin, c-telopeptide, ALP, Ca, and P), bone mineral density (BMD), duration of bisphosphonate (BP) usage, and lateral bowing of the femur at time of the fracture. All AFFs happened in female patients (mean age, 73.8 years) who have received bisphosphonate treatments except three patients. The mean duration of bisphosphonate usage was 95.3 months. Between the two groups, demographic data (age, height, weight, and BMI), underlying diseases, laboratory findings, hip BMD, and duration of BP treatment were comparable to each other (p > 0.05). However, the subtrochanteric fracture group showed higher FNSBA (femoral neck shaft bowing angle, p group. Angle of lateral bowing (FNSBA) and spine BMD showed significant differences between

    Gyrodactylus aff. mugili Zhukov, 1970 (Monogenoidea: Gyrodactylidae) is recorded and described from the gill lamellae of 11 of 35 greenback mullet, Chelon subviridis (Valenciennes) (minimum prevalence 31%), from the brackish waters of the Shatt Al-Arab Estuary in southern Iraq. The gyrodactylid was also found on the gill lamellae of one of eight Speigler's mullet, Valamugil speigleri (Bleeker), from the brackish waters of the Shatt Al-Basrah Canal (minimum prevalence 13%). Fifteen Klunzinger's mullet, Liza klunzingeri (Day), and 13 keeled mullet, Liza carinata (Valenciennes), collected and examined from southern Iraqi waters, were apparently uninfected. The gyrodactylids from the greenback mullet and Speigler's mullet were considered to have affinity to G. mugili Zhukov, 1970, and along with G. mugili may represent members of a species complex occurring on mullets in the Indo-Pacific Region. A single damaged gyrodactylid from the external surfaces of the abu mullet, Liza abu (Heckel), was insufficient for species identification. Previously identified species of Gyrodactylus recorded on L. abu in Iraq by various authors were considered possible misidentifications or accidental infections.

    Full Text Available Smilax L. in Brazil is represented by 32 taxa and it is a taxonomically difficult genus because the plants are dioecious and show wide phenotypic variation. The analysis and use of leaf anatomy characters is recognized as a frequently successful taxonomic method to distinguish between individual taxon, when floral material is absent or minute differences in flowers and foliage exist such as in Smilax. The aim of this study was to characterize the anatomical features of the aerial organs in Smilax syphilitica collected from the Atlantic Rainforest, in Santa Teresa-ES and the Smilax aff. syphilitica from the Amazon Rainforest, in Manaus, Brazil. For this, a total of three samples of Smilax were collected per site. Sample leaves and stems were fixed with FAA 50, embedded in historesin, sectioned on a rotary microtome, stained and mounted in synthetic resin. Additionally, histochemical tests were performed and cuticle ornamentation was analyzed with standard scanning electron microscopy. S. syphilitica and S. aff. syphilitica differed in cuticle ornamentation, epidermal cell arrangement and wall thickness, stomata type and orientation, calcium oxalate crystal type, and position of stem thorns. Leaf blades of S. syphilitica from the Amazon Rainforest have a network of rounded ridges on both sides, while in S. aff. syphilitica, these ridges are parallel and the spaces between them are filled with numerous membranous platelets. Viewed from the front, the epidermal cells of S. syphilitica have sinuous walls (even more pronounced in samples from the Amazon; while in S. aff. syphilitica, these cells are also sinuous but elongated in the cross-section of the blade and arranged in parallel. Stomata of S. syphilitica are paracytic, whereas in S. aff. syphilitica, are both paracytic and anisocytic, and their polar axes are directed towards the mid-vein. Calcium oxalate crystals in S. syphilitica are prisms, whereas in S. aff. syphilitica, crystal sand. Thorns

  3. MANAGEMENT OF ENDOCRINE DISEASE: Atypical femoral fractures: risks and benefits of long-term treatment of osteoporosis with anti-resorptive therapy.

    Science.gov (United States)

    Adler, Robert A

    2018-03-01

    Modern osteoporosis treatment began in the mid-1990s with the approval of amino-bisphosphonates, anti-resorptive agents that have been shown to decrease osteoporotic fracture risk by about half. In 2005, the first cases of atypical femoral fractures (AFF), occurring in the shaft of the femur, were reported. Since then, more cases have been found, leading to great concern among patients and a dramatic decrease in bisphosphonate prescribing. The pathogenesis and incidence of AFF are reviewed herein. Management and an approach to prevention or early detection of AFF are also provided. Denosumab, a more recently approved anti-resorptive medication has also been associated with AFF. Long-term management of osteoporosis and prevention of fracture are challenging in light of this serious but uncommon side effect, yet with an aging population osteoporotic fracture is destined to increase in frequency. © 2018 European Society of Endocrinology.

    Flow fractionation of cells using physical fields to achieve lateral displacement finds wide applications, but its extension to surface molecule-specific separation requires labeling. Here we demonstrate affinity flow fractionation (AFF) where weak, short-range interactions with asymmetric molecular patterns laterally displace cells in a continuous, label-free process. We show that AFF can directly draw neutrophils out of a continuously flowing stream of blood with an unprecedented 400,000-fold depletion of red blood cells, with the sorted cells being highly viable, unactivated, and functionally intact. The lack of background erythrocytes enabled the use of AFF for direct enumeration of neutrophils by a downstream detector, which could distinguish the activation state of neutrophils in blood. The compatibility of AFF with capillary microfluidics and its ability to directly separate cells with high purity and minimal sample preparation will facilitate the design of simple and portable devices for point-of-care diagnostics and quick, cost-effective laboratory analysis.

    The degree of overlap between schizophrenia (SCZ) and affective psychosis (AFF) has been a recurring question since Kraepelin's subdivision of the major psychoses. Studying nonpsychotic relatives allows a comparison of disorder-associated phenotypes, without potential confounds that can obscure distinctive features of the disorder. Because attention and working memory have been proposed as potential endophenotypes for SCZ and AFF, we compared these cognitive features in individuals at familial high-risk (FHR) for the disorders. Young, unmedicated, first-degree relatives (ages, 13-25 years) at FHR-SCZ (n=41) and FHR-AFF (n=24) and community controls (CCs, n=54) were tested using attention and working memory versions of the Auditory Continuous Performance Test. To determine if schizotypal traits or current psychopathology accounted for cognitive deficits, we evaluated psychosis proneness using three Chapman Scales, Revised Physical Anhedonia, Perceptual Aberration, and Magical Ideation, and assessed psychopathology using the Hopkins Symptom Checklist -90 Revised. Compared to controls, the FHR-AFF sample was significantly impaired in auditory vigilance, while the FHR-SCZ sample was significantly worse in working memory. Both FHR groups showed significantly higher levels of physical anhedonia and some psychopathological dimensions than controls. Adjusting for physical anhedonia, phobic anxiety, depression, psychoticism, and obsessive-compulsive symptoms eliminated the FHR-AFF vigilance effects but not the working memory deficits in FHR-SCZ. The working memory deficit in FHR-SZ was the more robust of the cognitive impairments after accounting for psychopathological confounds and is supported as an endophenotype. Examination of larger samples of people at familial risk for different psychoses remains necessary to confirm these findings and to clarify the role of vigilance in FHR-AFF.

    Injury triggers regeneration of axons and dendrites. Research has identified factors required for axonal regeneration outside the CNS, but little is known about regeneration triggered by dendrotomy. Here, we study neuronal plasticity triggered by dendrotomy and determine the fate of complex PVD arbors following laser surgery of dendrites. We find that severed primary dendrites grow toward each other and reconnect via branch fusion. Simultaneously, terminal branches lose self-avoidance and grow toward each other, meeting and fusing at the tips via an AFF-1-mediated process. Ectopic branch growth is identified as a step in the regeneration process required for bypassing the lesion site. Failure of reconnection to the severed dendrites results in degeneration of the distal end of the neuron. We discover pruning of excess branches via EFF-1 that acts to recover the original wild-type arborization pattern in a late stage of the process. In contrast, AFF-1 activity during dendritic auto-fusion is derived from the lateral seam cells and not autonomously from the PVD neuron. We propose a model in which AFF-1-vesicles derived from the epidermal seam cells fuse neuronal dendrites. Thus, EFF-1 and AFF-1 fusion proteins emerge as new players in neuronal arborization and maintenance of arbor connectivity following injury in Caenorhabditis elegans. Our results demonstrate that there is a genetically determined multi-step pathway to repair broken dendrites in which EFF-1 and AFF-1 act on different steps of the pathway. EFF-1 is essential for dendritic pruning after injury and extrinsic AFF-1 mediates dendrite fusion to bypass injuries. PMID:28283540

    Full Text Available Bifacial points have been used to characterize the “Umbu” tradition in southern and southeastern Brazil. This archaeological tradition has been related to sites dated from the late Pleistocene-early Holocene boundary to near historical times. Such a huge temporal range and vast territory have suggested the existence of greater diversity within this tradition that has been ignored thus far due to the lack of systematic regional studies of such points. Through geometric morphometric analysis, this article aims to test the hypothesis that there are substantial differences in the Holocene bifacial points associated with the Umbu tradition in southeastern Brazil. Five landmarks were digitized in standardized photographs from 658 points from the states of São Paulo, Paraná, Santa Catarina, and Rio Grande do Sul. The results show that points made by groups from southeastern Brazil (São Paulo state present a very distinct morphology (size and shape in comparison to  those made by the southern groups (Paraná, Santa Catarina and Rio Grande do Sul. This would indicate a regional identity shared only by some groups from São Paulo (at least regarding the projectile points. It is possible that Umbu tradition presents a more restricted range, both in chronological and spatial terms, than the one proposed so far.

    We herein report two cases of atypical femoral fracture (AFF). X-ray examinations at the first visit of these two female patients showed a complete fracture of the femoral diaphysis diagnosed as an atypical femoral fracture (AFF). X-rays of these two cases also showed localized cortical thickening of the femoral diaphysis. Both patients had been taking alendronate for more than 3 years because of postmenopausal osteoporosis. We assumed that both of the fractures were associated with the long-term use of alendronate. However, we retrospectively identified localized cortical thickening of the femoral diaphysis on an X-ray taken before the alendronate therapy in both of these cases. Therefore, we suspected a pathogenesis of AFFs in which preexisting stress or an insufficient fracture unrelated to bisphosphonate (BP) therapy and subsequent suppression of bone turnover due to BP administration led to the occurrence of an AFF. The patient underwent surgery using intramedullary nails in both of these cases, followed by the administration of teriparatide, and they were able to walk without any support at the final follow-up examination.

    Full Text Available The Cova des Pas de Vallgornera is the longest cave of Mallorca (Balearic Islands, Western Mediterranean and one of the 30 longest caves in the world. The exploration of one of the galleries allowed the discovery of a fossiliferous deposit of vertebrate remains in a remarkable preservation state. The fossil faunal complex found in this gallery is composed of up to 5 mammalian species (Myotragus aff. kopperi, Hypnomys onicensis, Nesiotites aff. ponsi, Rhinolophus aff. mehelyi and Pipistrellus sp., at least 14 bird species (among them two Mallorcan endemic taxa: Pica mourerae and Athene vallgornerensis, one reptile (Podarcis aff. lilfordi and one amphibian (Discoglossus sp.. This faunal composition is similar to the one recorded in the Pedrera de s’Ònix, a well known deposit from the Early Pleistocene of Mallorca, and shared morphological characteristics between taxa of both deposits suggest that the chronology of the Cova des Pas de Vallgornera should be considered Early Pleistocene as well. Both taxonomical analysis and chronology of this fauna furnished information on some speleological aspects of the cave.

In this report, we review studies on the epidemiology, pathogenesis, and medical management of AFFs, published since 2010. This newer evidence suggests that AFFs are stress or insufficiency fractures. The original case definition was revised to highlight radiographic features...... a minor to a major feature. The association with specific diseases and drug exposures was removed from the minor features, because it was considered that these associations should be sought rather than be included in the case definition.

    Full Text Available In this paper, two powerful analytical methods known as modified homotopy perturbation method and Amplitude Frequency Formulation called respectively MHPM and AFF, are introduced to derive approximate solutions of a system of ordinary differential equations appear in mechanical applications. These methods convert a difficult problem into a simple one, which can be easily handled. The obtained solutions are compared with numerical fourth order runge-kutta method to show the applicability and accuracy of both MHPM and AFF in solving this sample problem. The results attained in this paper confirm the idea that MHPM and AFF are powerful mathematical tools and they can be applied to linear and nonlinear problems.

    Induced plant responses to leaf-chewing insects have been well studied, but considerably less is known about the effects of phloem-feedings insects on induction. In a set of laboratory experiments, we examined density-dependent induction by the milkweed-oleander aphid, Aphis nerii, of putative defenses in four milkweed species (Asclepias incarnata, Asclepias syriaca, Asclepias tuberosa, and Asclepias viridis). We hypothesized that high aphid density would lead to increased cardenolide expression in species with low constitutive levels of cardenolides (e.g., A. tuberosa), but that there would be no induction in high constitutive cardenolide species (e.g., A. viridis). Based on previous studies, we did not expect cardenolide induction in A. incarnata. Contrary to our predictions, we observed feeding-induced declines of cardenolide concentrations in A. viridis. Cardenolide concentrations did not respond to aphid feeding in the other three milkweed species. Aphids also caused reductions in biomass accumulation by two of four Asclepias species, A. viridis and A. incarnata. High aphid density led to a decrease in A. viridis foliar nitrogen concentration. However, aphids had no effect on the defensive chemistry, growth, or nutritional quality of either A. syriaca or A. tuberosa. Our results highlight that congeneric plant species may respond differently to the same levels of herbivore damage.

    In orchard production, fruit abscission is common due to insect damage, disease, crop thinning and natural dropping. However, the utilization of these discarded plant resources has received little research attention. In this study, we used apple fruit from such plant resources, mainly young and mature dropped fruit, as materials and mixed them with a fermentation agent, brown sugar and water. The effects of the proportion of fermentation agent and the fermentation conditions (O2, temperature, fermenting time and fruit crushing degree) were studied using an orthogonal experimental design. We discovered a novel fermented fertilizer, apple fruit fermentation nutrient solution (AFF), for which the optimal fermentation formula and conditions were comminuted young apples: fermentation agent: brown sugar: water weight ratio of 5:0.1:1:4 and 45 days of aerobic fermentation. Analysis of the fermentation solutions showed that the supernatant obtained using these optimized parameters had the highest mineral element content among the fermentation formulas and conditions studied. The results of a spraying experiment with 200-, 500- and 800-fold dilutions showed that AFF significantly promoted the net photosynthetic rate, leaf area and thickness, specific leaf weight, and chlorophyll and mineral element content in the leaves of young apple trees relative to the control treatment. The effects of 200-fold diluted AFF on the photosynthetic rate, the developmental quality and mineral element contents were greater than those of the 500- and 800-fold dilutions. The results of the spraying of adult trees with 200-fold diluted AFF compared to a water control demonstrated that AFF significantly enhanced the average weight of a single fruit, the shape index, hardness, content of soluble solids, titratable acid content, vitamin C content, and aroma compound content of the fruit of the adult trees. This evidence suggests that the AFF obtained using the optimal production process could

    1999-12-01

    Full Text Available Studies from some semi-arid regions of the world have shown the beneficial effect of trees in silvopastoral systems, by promoting the formation of resource islands and increasing the sustainability of the system. No data are available in this respect for tree species of common occurrence in semi-arid Northeastern Brazil. In the present study, conducted in the summer of 1996, three tree species (Zyziphus joazeiro, Spondias tuberosa and Prosopis juliflora: found within Cenchrus ciliaris pastures were selected to evaluate differences on herbaceous understory and soil chemical characteristics between samples taken under the tree canopy and in open grass areas. Transects extending from the tree trunk to open grass areas were established, and soil (0-15 cm and herbaceous understory (standing live biomass in 1 m² plots samples were taken at 0, 25, 50, 100, 150 and 200% of the average canopy radius (average radius was 6.6 ± 0.5, 4.5 ± 0.5, and 5.3 ± 0.8 m for Z. joazeiro, P. juliflora, and S. tuberosa , respectively. Higher levels of soil C, N, P, Ca, Mg, K, and Na were found under the canopies of Z. joazeiro and P. juliflora: trees, as compared to open grass areas. Only soil Mg organic P were higher under the canopies of S. tuberosa trees, as compared to open grass areas. Herbaceous understory biomass was significantly lower under the canopy of S. tuberosa and P. juliflora trees (107 and 96 g m-2, respectively relatively to open grass areas (145 and 194 g m-2. No herbaceous biomass differences were found between Z. joazeiro canopies and open grass areas (107 and 87 g m-2, respectively. Among the three tree species studied, Z. joazeiro was the one that presented the greatest potential for use in a silvopastoral system at the study site, since it had a larger nutrient stock in the soil without negatively affecting herbaceous understory biomass, relatively to open grass areas.

    The biology and outcome of adult t(4;11)(q21;q23)/MLL-AFF1 acute lymphoblastic leukemia are poorly understood. We describe the outcome and delineate prognostic factors and optimal post-remission therapy in 85 consecutive patients (median age 38 years) treated uniformly in the prospective trial UKALLXII/ECOG2993. The immunophenotype of this leukemia was pro-B (CD10NEG). Immaturity was further suggested by high expression of the stem-cell antigens, CD133 and CD135, although CD34 expression was significantly lower than in t(4;11)-negative patients. Complete remission was achieved in 77 (93%) patients but only 35% survived 5 years (95% CI: 25–45%); the relapse rate was 45% (95% CI: 33–58%). Thirty-one patients underwent allogeneic transplantation in first remission (15 sibling donors and 16 unrelated donors): with 5-year survival rates of 56% and 67% respectively, only 2/31 patients relapsed. This compares with a 24% survival rate and 59% relapse rate in 46 patients who received post-remission chemotherapy. A major determinant of outcome was age with 71% of patients aged <25 years surviving. Younger patients had lower relapse rates (19%) but most received allografts in first complete remission. In conclusion, multivariate analysis did not demonstrate an advantage of allografting over chemotherapy but only five younger patients received chemotherapy. Prospective trials are required to determine whether poor outcomes in older patients can be improved by reduced-intensity conditioning allografts. NCT00002514 www.clinicaltrials.gov PMID:23349309

    The investigation of extracts from six species of marine invertebrates yielded one new and several known natural products. Isoptilocaulin from the sponge Monanchora aff. arbuscula displayed antimicrobial activity at 1.3 mg/mL against an oxacillin-resistant strain of Staphylococcus aureus. Five inactive known dibromotyrosine derivatives, 2 6, were isolated from a new species of marine sponge, Aplysina sp. The sponges Petromica ciocalyptoides and Topsentia ophiraphidites yielded the known halistanol sulfate A (7) as an inhibitor of the antileishmanial target adenosine phosphoribosyl transferase. The ascidian Didemnum ligulum yielded asterubin (10) and the new N,N-dimethyl-O-methylethanolamine (11). The octocoral Carijoa riisei yielded the known 18-acetoxypregna-1,4,20-trien-3-one (12), which displayed cytotoxic activity against the cancer cell lines SF295, MDA-MB435, HCT8 and HL60. (author)

    2012-09-01

    Full Text Available Smilax L. in Brazil is represented by 32 taxa and it is a taxonomically difficult genus because the plants are dioecious and show wide phenotypic variation. The analysis and use of leaf anatomy characters is recognized as a frequently successful taxonomic method to distinguish between individual taxon, when floral material is absent or minute differences in flowers and foliage exist such as in Smilax. The aim of this study was to characterize the anatomical features of the aerial organs in Smilax syphilitica collected from the Atlantic Rainforest, in Santa Teresa-ES and the Smilax aff. syphilitica from the Amazon Rainforest, in Manaus, Brazil. For this, a total of three samples of Smilax were collected per site. Sample leaves and stems were fixed with FAA 50, embedded in historesin, sectioned on a rotary microtome, stained and mounted in synthetic resin. Additionally, histochemical tests were performed and cuticle ornamentation was analyzed with standard scanning electron microscopy. S. syphilitica and S. aff. syphilitica differed in cuticle ornamentation, epidermal cell arrangement and wall thickness, stomata type and orientation, calcium oxalate crystal type, and position of stem thorns. Leaf blades of S. syphilitica from the Amazon Rainforest have a network of rounded ridges on both sides, while in S. aff. syphilitica, these ridges are parallel and the spaces between them are filled with numerous membranous platelets. Viewed from the front, the epidermal cells of S. syphilitica have sinuous walls (even more pronounced in samples from the Amazon; while in S. aff. syphilitica, these cells are also sinuous but elongated in the cross-section of the blade and arranged in parallel. Stomata of S. syphilitica are paracytic, whereas in S. aff. syphilitica, are both paracytic and anisocytic, and their polar axes are directed towards the mid-vein. Calcium oxalate crystals in S. syphilitica are prisms, whereas in S. aff. syphilitica, crystal sand. Thorns

En este trabajo realizamos un estudio comparativo de las secuencias reguladoras del gen de la chalcón sintetasa de varias familias botánicas. Veintidós secuencias de promotores de Chalcone Synthase fueron comparados teniendo en cuenta tres elementos Cis reguladores: Caja-G, Caja-H y Caja-TATA, que podrían estar actuando como una sola unidad cooperativa. Nuestra comparación muestra que estos elementos puede que se conserven en algunas especies e inclusive que se conserven a nivel de familia. Sin embargo, en algunas especies no todos los elementos Cis fueron encontrados, mostrando que no todas las especies se regulan bajo los mismos parámetros. Adicionalmente, una comparación entre promotores de una misma especie con una familia de multigenes Chs, mostró que los genes duplicados son variables en la composición del elemento Cis, sugiriendo que estos genes pueden estarse expresando de maneras diferentes.

    Full Text Available Várias espécies herbáceas e subarbustivas, nativas do Cerrado no Brasil, são geofitas, ou seja, sobrevivem ao período desfavorável de déficit hídrico e de baixas temperaturas, que muitas vezes coincide com incêndios, mantendo apenas a porção subterrânea. Vernonia oxylepis é uma dessas espécies e o objetivo desse estudo foi descrever a morfoanatomia da raiz tuberosa e a formação das gemas nessa raiz. Tal raiz é constituída de um eixo orientado perpendicularmente no solo, a partir do qual ramos aéreos são formados na porção proximal, situada ao nível do solo, ao longo do ciclo de vida da planta. Na porção proximal da raiz ocorre auto-enxertia da base dos ramos por ela emitidos. A raiz acumula lipídios e frutanos, apresenta ligeira contração e forma gemas reparativas; a formação das gemas adventícias se dá a partir do periciclo proliferado. Tais características poderiam ser associadas ao processo de adaptação da espécie às condições do Cerrado.Several native herbaceous and subshrub species native to the Cerrado in Brazil are geophytes, that is, they survive the unfavorable dry season and low temperatures, that sometimes coincide with fire, with only the underground system intact. Vernonia oxylepis is one of these species and the aim of this study was to describe the morpho-anatomy of the tuberous root and bud formation on this structure. The main axis of this root is perpendicular to the soil surface, and from which aerial shoots arise periodically throughout the life cycle. On the upper portion of the root, self-grafting of the shoots occurs. The root stores lipids and fructans, exhibits contraction and produces reparatory buds; adventitious buds arise from proliferated pericycle. These characteristics may be related to adaptation of this species to conditions in the Cerrado.

    Cracids are medium to large frugivorous birds that are endemic to the Neotropics. Because of deforestation and overhunting, many species are threatened. The conservation of several species has relied on captive breeding and reintroduction in the wild, but captive populations may be inbred. Microsatellite tools can permit the construction of genetic pedigrees to reduce inbreeding, but only a few loci are available for this group of birds. Here, we present 10 novel polymorphic microsatellite loci and the cross-amplification of these and of 10 additional loci available in the literature in a panel of 5 cracid species, including 3 species with high conservation concern. We provide the first polymorphic loci for the jacutinga, Aburria jacutinga (N = 8), and red-billed curassow, Crax blumenbachii (N = 9), and additional loci for bare-faced curassow, C. fasciolata (N = 8), Alagoas curassow, Pauxi mitu (N = 5), and razor-billed curassow, P. tuberosa (N = 5). The average number of alleles was 2.9 for A. jacutinga, 2.7 for C. blumenbachii, 3.5 for C. fasciolata, 2.6 for P. mitu, and 5.7 for P. tuberosa. The mean expected heterozygosities were 0.42, 0.40, 0.48, 0.37, and 0.59, respectively. The average probabilities that the set of loci would not exclude a pair of parents of an arbitrary offspring were 2.9% in A. jacutinga, 1% in C. blumenbachii, 0.5% in C. fasciolata, 0.4% in P. mitu, and 0.002% in P. tuberosa suggesting that these loci may be adequate for parentage analysis and to implement ex situ genetic management plans.

    To investigate the advantages of using tomosynthesis (TS) compared to radiographs in the detection, characterization, and follow-up of bisphosphonate-related atypical femur fractures (BP-AFF). Eight patients were identified retrospectively who underwent TS for radiographic findings suspicious for BP-AFF. Two radiologists independently interpreted 15 radiographs and 16 TS examinations, indicating the presence or absence of the following: (1) cortical "beaking" on radiographs, (2) radiolucent fracture line on radiographs, and (3) fracture lucency on TS corresponding to the site of radiographic abnormality. Radiation dose data were calculated for radiographs and TS using Monte Carlo analysis. There was agreement on 100 % of radiographs regarding the presence or absence of a cortical beak. Regarding the presence or absence of a fracture lucency, there was agreement on 100 % of TS examinations (Kappa = 1.0) and 73 % of radiographs (Kappa = 0.40 ± 0.24). For the 46 % of radiographs in which one or both radiologists did not visualize a fracture line, there was 100 % agreement for the presence of a fracture line on the corresponding TS. The interobserver agreement for fracture line detection was significantly higher for TS than for radiographs (p = 0.012). The effective radiation dose using TS was approximately 96 % lower compared to radiography. TS outperformed radiographs in the detection and characterization of BP-AFF. TS may also have advantages over radiography for BP-AFF follow-up through its unique ability to visualize fracture healing with lower effective radiation doses to the patient.

    Roughly half of the femoral fracture patients diagnosed with AFF according to the criteria suggested by a task force of the American Society for Bone and Mineral Research (ASBMR) have not undergone bisphosphonate (BP) therapy. One suspected cause of such fractures is severe bone loss due to osteomalacia, but the pathogenesis remains unknown. We report a case of an 84-year-old woman with AFF not treated by BP therapy, in whom underlying osteomalacia was histologically diagnosed. The involvement of femoral curvature and spino-pelvic malaligment in the fracture in the present case was considered.

    Apathy symptoms include different dimensions: cognitive (C), emotional-affective (E-Aff) and auto-activation; they have been related to dysfunctions of the dorsolateral, orbito-basal prefrontal cortex and the subcortical frontal connections to the basal ganglia, respectively. In Alzheimer's disease (AD), an association has been found between apathy severity and both executive deficits and atrophy of the dorso-lateral prefrontal cortex; however, it is not clear whether these associations concern only the cognitive aspects of apathy. Furthermore, whether there is an association in AD between E-aff apathy and theory of mind (ToM),the cognitive functions subsumed by the orbito-basal prefrontal cortex, has not been investigated. Aim of the study was to investigate the relationship between C, E-Aff and auto-activation apathy and performance on tasks investigating executive and ToM cognitive functions in AD. For this purpose, 20 AD patients with apathy and 20 matched controls were submitted to an executive and ToM neuropsychological assessment. Apathy was assessed with a weekly diary (ApD) created specifically to assist caregivers in quantifying the C, E-Aff and auto-activation symptomatology of apathy. Correlational analyses showed that AD patients' scores on the Modified Card Sorting Test (MCST) and Emotion Attribution tasks were correlated with most ApD scores. However, regression analyses showed that C diary scores were predicted by MCST performance, E-Aff diary scores by performance on the E-Attribution task and ApD scores measuring auto-activation apathy were predicted by both the MCST and the Emotion Attribution scores. These results confirm the co-occurrence of apathy and executive-function deficits in AD and suggest a specific association between AD patients' executive deficits and the cognitive component of apathy. Furthermore, they document, for the first time, an association between poor performance on tests assessing ToM abilities and the emotional

    The objective of our study was to compare subtrochanteric femur bone mineral density (BMD) and bone quality of long-term bisphosphonate (BP) users who sustained an atypical femoral fracture (AFF) with BP users who did not sustain a femoral fracture and BP-naïve patients with no history of femoral fracture using quantitative CT (QCT). Fourteen female BP users with an AFF (mean age, 72.6 years; mean duration of BP use, 6.2 years; mean body mass index, 21.9) who had undergone QCT before fracture events were sex-, age-, BP use duration-, and body mass index-matched to 14 BP users who did not sustain a fracture and 14 BP-naïve patients. The lateral cortical thickness index (CTI) and the mean BMD (BMD mean ) and SD of the BMD (BMD SD ) within the lateral cortex and within the entire cross-sectional area of the subtrochanteric femur were measured on axial QCT. Femoral neck-shaft angles were measured on the QCT scout image. Parameters were analyzed using the Kruskal-Wallis test. Lateral CTIs were greater in the BP users with an AFF (median, 0.28) than in the BP users without a femoral fracture (median, 0.21) (p = 0.038) and the BP-naïve group (median, 0.21) (p = 0.009). The lateral cortex BMD SD was significantly higher in the BP users with an AFF (median, 59.59 mg/cm 3 ) than the BP users without a femoral fracture (median, 39.27 mg/cm 3 ; p = 0.049) and the BP-naïve group (median, 31.02 mg/cm 3 ; p = 0.037). There was no significant difference among groups in lateral cortex BMD mean , BMD mean and BMD SD of the entire cross-sectional area, and femoral neck-shaft angle. Long-term BP users with a subsequent AFF had a thicker lateral cortex and higher lateral cortex BMD SD at the subtrochanteric area before the fracture on QCT than BP users who did not sustain a femoral fracture and BP-naïve patients.

    Full Text Available Pre-germination treatments such as scarification and the use of growth regulators can provide the dormancy breaking in seeds and enhance the emergence and development of seedlings. The aim of this study was to determine appropriate treatments to overcome seed dormancy and enhance the initial growth of seedlings of Spondias tuberosa. We used a randomized design in factorial 2 x 4, with the following factors: seeds scarified or not scarified and then soaked in water or aqueous solutions of gibberellin, cytokinin and ethylene, with 4 replicates and 15 seeds. There was no significant interaction between scarification treatments and use of growth regulators. Mechanical scarification and soaking seeds in solutions containing umbuzeiro growth regulators does not increase the percentage of seedling emergence, however soaking in a solution of Ethrel at 100 ppm provides higher speed of emergence and root development. Tratamentos pré-germinativos, como a escarificação e o uso de reguladores de crescimento, podem proporcionar a superação de dormência em sementes e incrementar a emergência e o desenvolvimento de plântulas.

    A research on the application of MSSIP-2 nutrient in marine phytoplankton culture has been conducted to produce biomass to be used as raw material for biofuel. Marine phytoplankton was cultivated using the nutrient media and the growth rates were studied by measuring the cell solidity at various growth times. Seven phytoplanktons; Isochrysis aff galbana, Spirulina sp., Thalassiosira sp., and Nitzchia sp., Chlorella vulgaris, Chaetoceros calcitrans and Isochrysis tahiti were used in the research. The experimental temperature, salinity, and pH of the media were measured and the specific growth rates of phytoplanktons were determined using the first order rate equation. Results showed that the highest specific growth rate was given by Chlorella vulgaris (0.0322 cells/hour) and the lowest one was by Thalassiosira sp. (0.0277 cells/hour). The highest biomass weight was obtained from Isochrysis aff galbana (0.329 g), whereas the lowest one (0.27 g) was from Nitzchia sp. The carbohydrate content was various, the highest content was 34.07% found in Isochrysis aff galbana and the lowest was 28.16% in Thalassiosira sp.

    Full Text Available What is the importance of open habitat in a predominantly closed forest to the dung beetle assemblage? The Atlantic Forest in Brazil is one of the most highly disturbed ecosystems and is mainly represented by fragmented areas. However, in places where human disturbances have ceased, certain areas are showing a natural regeneration pattern. The aim of the present study was to determine how the dung beetle assemblage responds to distinct habitat structures in a fragment of Atlantic Forest. For such, open and closed forest areas were sampled in a fragment of the Atlantic Forest in the northeastern region of Brazil. Pitfall traps baited with excrement and carrion were used to collect the beetles. A total of 7,267 individuals belonging to 35 species were captured. Canthon chalybaeus and C. mutabilis were restricted to open areas. Nearly 90% of the individuals of C. aff. simulans and Deltochilum aff. irroratum were identified in these areas. A higher percentage (> 50% of Canthon staigi, Dichotomius aff. depressicolis and D. aff. sericeus occurred in closed areas. Abundance differed between areas, with higher values in closed areas. Richness was not influenced by the habitat structure. NMDS ordination exhibited the segregation of areas and ANOSIM confirmed that this variable explained the assemblage of dung beetle species. The findings of the present study validate that open areas are associated to more restrictive conditions, limiting a higher abundance of dung beetle. Although situated near preserved fragments, the studied open areas increase the heterogeneity of the general landscape.

    Full Text Available The calico box crab Hepatus epheliticus is an abundant species from shallow and continental shelf waters of the Atlantic coast of USA and Mexico. Information about population structure and sexual maturity is absent, even though this crab is caught to be used as bait for the octopus fishery in the Campeche Bank, Mexico. In order to achieve such information, a total of 768 individuals were collected from January to March 2010 through baited traps installed in the Yucatan Peninsula, Mexico. Our results showed that sex ratio is biased towards more males than females (1:0.55, contradicting to that reported in other brachyuran crabs. The absence of ovigerous females suggests that they did not enter into the traps during embryogenesis. Males reached a larger maximum size than females (64.0 ± 6.15 and 58.4 ± 5.60 mm carapace width, respectively. The general scheme of growth being positive allometric throughout ontogeny of both sexes. Males presented a transition phase from juveniles to adult corresponding to the puberty moult. The estimation of the onset of functional sexual maturity revealed a steady situation for the population, with 21.5 and 13.8% of males and females, respectively, morphologically immature at the time of catch. This study constitutes the first report on population structure and sexual maturity in a population of the calico box crab H. epheliticus.El cangrejo caja moteado Hepatus epheliticus es un abundante braquiuro perteneciente a la familia Hepatidae, distribuido desde aguas someras hasta la plataforma continental en la costa atlántica de Estados Unidos y México.

    Full Text Available La actual crisis financiera internacional está actuando como catalizador de un profundo proceso de cambio en el sector bancario español que está afectando también a las entidades de crédito de la Economía Social: cajas de ahorros y cooperativas de crédito. Su modelo de banca “minorista”, centrada en la cercanía al cliente, se ha visto acompañado en los últimos años de un fuerte proceso de expansión geográfica que ha supuesto un sobredimensionamiento de su red de sucursales. Sin embargo, como consecuencia de las actuales circunstancias de la economía española en general, y del sistema bancario en particular, dicha estrategia de desarrollo interno no parece sostenible, siendo necesario que se produzca un redimensionamiento del sector, para ver recuperada la confianza en el sistema y para que éste vuelva a ser considerado como uno de los más solventes del mundo. Bajo este enfoque, el objetivo de este trabajo es analizar las distintas estrategias de expansión territorial desarrolladas por dichas entidades con el objetivo de plasmar su situación actual y comprender por qué es necesaria la reestructuración del sector. Para ello se ha empleado tanto el análisis descriptivo como el econométrico, utilizando en todo momento los datos que presentan la Confederación Española de Cajas de Ahorros (CECA y la Unión Nacional de Cooperativas de Crédito (UNACC en sus anuarios estadísticos. / The current financial international crisis is acting as catalyst of a deep process of change in the Spanish banking sector which is affecting also the credit institutions of the Social Economy: saving banks and credit cooperatives.

    Full Text Available Osteoporosis is a common condition with significant health care costs. First-line therapy is with bisphosphonates, which have proven anti-fracture efficacy. Around 10 years after the introduction of bisphosphonates reports began to be published of atypical femoral fractures (AFFs that may be associated with this therapy. These fractures are associated with significant morbidity although lower mortality than the more common osteoporotic neck-of-femur fractures. A case definition has been described to allow identification of this class of fracture. Further work has established a high relative risk of AFFs in patients treated with bisphosphonates, but a low absolute risk in comparison to that of osteoporotic fractures. Proposed pathological mechanisms include low bone turnover states leading to stress/insufficiency fractures. Clinicians should be aware of the risk of AFFs and in particular the high rate of prodromal thigh/groin pain that warrants investigation in a patient receiving a bisphosphonate. If an incomplete fracture is diagnosed then bisphosphonate therapy needs to be stopped and prophylactic surgery may be considered. Due to these rare side effects patients on bisphosphonates require regular review, and this is particularly advised after 5 years of oral or 3 years of intravenous therapy.

    Helminth infections are one of the seriously neglected potent diseases in many parts of the world. The problems of parasitic helminthes becoming resistant to currently available anthelmintic drugs pose a challenge for the search - relying on natural products - for new and better anthelmintics. In this paper, four abundant Philippine weeds: Chrysopogon aciculatus Trin. Cyperus brevifolius Rottb., Ruellia tuberosa Linn. and Saccharum spontaneum Linn. were investigated for their anthelmintic activities to establish basis of their folkloric claim. The hexane-soluble and chloroform-soluble extracts were obtained through sequential solvent partitioning of the crude ethanolic extract of the air-dried aerial part of each plant sample. Meanwhile, the decoction was obtained from fresh aerial part of the plant samples. All extracts were then subjected to in vitro anthelmintic screening at different concentration as per method of Ghosh, et al. against African nightcrawler earthworms (Eudrillus euginiae) in which the activity of the extracts was determined by correlation with time. The anthelmintic bioassay results revealed a dose-dependent toxicity relationship. It indicated relatively low anthelmintic activities of the decoction of the four plant samples as compared to their corresponding crude ethanol extracts. Among the crude ethanol extracts, C. brevifolius (CBE) gave fastest time to bring about paralysis and death to the test organisms at all concentrations tested. For the hexane extracts, R. tuberosa (RTH) gave better activity among other plant samples. Lastly, among the chloroform-soluble extracts, both that of C. brevifolius (CBC) and R. tuberosa (RTC) comparably showed strongest anthelmintic activities at all tested concentrations, thus, exhibited best anthelmintic activity that is remarkably comparable to the positive control, Mebendazole at the highest concentration tested. In fact, CBC and RTC showed highest anthelmintic potential compared to all extracts tested in

In the previous literature, there are few studies that consider this variable, since liquidity in most cases was measured with data obtained from the Balance Sheet and the Income Statement. Methodologically, we have used a multivariate panel data analysis applied to a sample of large Spanish companies not quoted on the stock exchange. Additionally, this work embeds into the theoretical debate existing in the literature about the determinants of the financial structure of firms. The results indicate that a data model based on figures from CSF, mainly the CFO, has predictive ability of the financial structure.

First of all, we analyse the growing net borrowing of the Spanish economy in the former economic expansion cycle and how the national financial institutions were the primary source of foreign financing. Secondly, we analyse the evolution of territorial localization of saving banks and credit co-operatives, and of their lending and borrowing transactions. In this analysis we are going to difference two periods: since the beginning of nineties until August 2007, the start of the international financial, and a second period since the fourth quarter 2007 until now.

    Full Text Available In this paper cranial, dental and postcraneal fossil remains of the Bovidae family from Tarazona de Aragón are described. There are two forms in this Middle Miocene paleontological site of the Ebro Basin according to the metric and morphological characteristics of the dentition and hom cores. One form is referred to Eotragus and classified as E. aff. sansaniensis, showing more developed features than the other Iberian forms of the same genus. The other form is classified provisionally as aff. Tethytragus because it is quite similar to the Iberian Tethytragus langai and differs from Eotragus. The two bovids from Tarazona show differences in size, hypsodoncy and dental morphology, especially the differences of development and prominence of the styles/stylideds and ribs are obvious.Se describen restos fósiles dentarios, craneales y postcraneales pertenecientes a la familia Bovidae del yacimiento de Tarazona de Aragón. Según las características morfológicas y métricas de la dentición y los núcleos óseos, existen dos formas en este yacimiento del Mioceno medio de la Cuenca del Ebro. Una ha sido atribuida al género Eotragus y clasificada como E. aff. sansaniensis, mostrando características más derivadas que el resto de las formas ibéricas del mismo género. La otra se clasifica, provisionalmente, como aff. Tethytragus, ya que guarda similitudes con la especie ibérica Tethytragus langai y diferencias evidentes con respecto a Eotragus. Los dos taxones se diferencian netamente respecto a la talla, hipsodoncia y morfología de la dentición; sobre todo, las diferencias de desarrollo y prominencia de los estilos/estílidos y costillas mismos son evidentes.

  9. Floral traits driving reproductive isolation of two co-flowering taxa that share vertebrate pollinators

    Floral attributes evolve in response to frequent and efficient pollinators, which are potentially important drivers of floral diversification and reproductive isolation. In this context, we asked, how do flowers evolve in a bat–hummingbird pollination system? Hence, we investigated the pollination ecology of two co-flowering Ipomoea taxa (I. marcellia and I. aff. marcellia) pollinated by bats and hummingbirds, and factors favouring reproductive isolation and pollinator sharing in these plants. To identify the most important drivers of reproductive isolation, we compared the flowers of the two Ipomoea taxa in terms of morphometry, anthesis and nectar production. Pollinator services were assessed using frequency of visits, fruit set and the number of seeds per fruit after visits. The studied Ipomoea taxa differed in corolla size and width, beginning and duration of anthesis, and nectar attributes. However, they shared the same diurnal and nocturnal visitors. The hummingbird Heliomaster squamosus was more frequent in I. marcellia (1.90 visits h−1) than in I. aff. marcellia (0.57 visits h−1), whereas glossophagine bats showed similar visit rates in both taxa (I. marcellia: 0.57 visits h−1 and I. aff. marcellia: 0.64 visits h−1). Bat pollination was more efficient in I. aff. marcellia, whereas pollination by hummingbirds was more efficient in I. marcellia. Differences in floral attributes between Ipomoea taxa, especially related to the anthesis period, length of floral parts and floral arrangement in the inflorescence, favour reproductive isolation from congeners through differential pollen placement on pollinators. This bat–hummingbird pollination system seems to be advantageous in the study area, where the availability of pollinators and floral resources changes considerably throughout the year, mainly as a result of rainfall seasonality. This interaction is beneficial for both sides, as it maximizes the number of potential pollen vectors for plants and

The extracts found to be active intracellularly were further studied axenically under reducing oxygen concentrations. Results and Conclusions. Intracellular multiplication was inhibited ≥60% by five of the twelve extracts. Amongst these 5 extracts, in axenic culture, P. nigrum (acetone was active under aerobic, microaerophilic, and anaerobic conditions indicating presence of multiple components acting at different levels and P. tuberosa (aqueous showed bactericidal activity under microaerophilic and anaerobic conditions implying the influence of anaerobiosis on its efficacy. P. nigrum (aqueous and A. calamus (aqueous and ethanol extracts were not active under axenic conditions but only inhibited intracellular growth of Mycobacterium tuberculosis, suggesting activation of host defense mechanisms to mediate bacterial killing rather than direct bactericidal activity.

    Patients with oncological pathology have attended daily in sessions for several weeks in the linear accelerator radiation therapy. Persons subject to this intervention have moved to the Hospital Mexico of the social security of Costa Rica, place that centralizes this treatment. The Caja Costarricense de Seguro Social (CCSS) has considered two options depending on the place of origin of users: bear the costs of commuting from the area of habitual residence, or place them temporarily in a shelter provided by the institution; the CCSS has chosen the first alternative. This research has consisted of a cost-minimization analysis between these two alternatives. The study population are patients with oncological pathology attending sessions of radiotherapy with linear accelerator at the Hospital Mexico in the first half of 2009 using ambulances of Cruz Roja Costarricense. The size of the study population is 107 persons, the total number of transferred recorded in the Fondo Rotatorio de Operaciones of Hospital Mexico is 998. Patients came from five regions and twenty areas of health according to the geographical division of the CCSS. The variables included have been: cost per day by way of transfer, which involves the distance to the radiotherapy center of Hospital Mexico and the cost of the rate at Cruz Roja ambulance per Km (326.86 colons, according to the agreement CCSS-Cruz Roja in June 2009) estimated daily cost of lodging in a shelter, and the reason daily cost of relocation / daily cost of shelter. The cost of shelter includes food and were used data from the company International Medical Suppliers S. A. as a basis for estimating the daily cost, the price fixed by the company was 65 dollars a day, and the conversion into colons exchange rate as established by the Banco Central de Costa Rica; dated April 30, 2010, the amount has been 33.542.60 colons. The reason for each area of health was given by the ratio of the average daily cost in colons by way of ambulance of

A produtividade de raízes tuberosas não diferiu entre os tratamentos, sendo os valores médios de 25,5 e 22,3 t ha-1para produtividades total e comercial, respectivamente. Assim, a utilização do bioestimulante interfere no número de raízes e de folhas de plantas de batata-doce, mas não favorece a produtividade de raízes tuberosas até a concentração de 15 mL L-1.

    Full Text Available Este estudo teve como objetivo otimizar a extração de ecdisterona em raízes de ginseng brasileiro. Primeiramente, para se avaliar a eficiência do solvente extrator, amostras de raízes dois acessos (BRA e JB-UFSM de P. glomerata foram extraídas em Soxhlet com metanol e clorofórmio, separadamente, durante 4 horas. No segundo ensaio, com o intuito de se escolher o método extrator, a extração foi conduzida em Soxhlet e em ultrassom, utilizando metanol como solvente. Em P. tuberosa, as amostras foram extraídas com metanol, e a extração foi conduzida em Soxhlet e em banho ultrasônico. O conteúdo de ecdisterona foi determinado em Cromatógrafo Líquido de Alta Eficiência (CLAE. Em ambas as espécies, um maior conteúdo de ecdisterona foi detectado nas amostras extraídas com metanol e em Soxhlet. A metodologia proposta mostrou-se eficaz para a quantificação da ecdisterona a partir das raízes de P. glomerata e P. tuberosa, podendo ser aplicada no controle de qualidade de drogas vegetais e/ou fitoterápicos.This study aimed at optimizing the extraction method from ecdysterone of Brazilian ginseng. Root samples of two accessions (BRA and JB-UFSM of P. glomerata were extracted in a Soxhlet with methanol or chloroform for 4h. In the second trial, the extration was conduced in a Soxhlet or ultrasonic using metanol as a solvent. In P. tuberosa, the roots samples were extracted with methanol in a Soxhlet or in ultrasonic. The ecdysterone content was determinated using high efficiency liquid chromatography methods. In both studied species, the highest ecdisterone content was detected from samples extracted in a Soxhlet and using methanol as a solvent. This extration method has been successfully applied for determination of ecdysterone content from roots of Brazilian ginseng, and could be useful for the quality control of drugs and pharmaceutical formulations.

    Full Text Available Tuberous sclerosis (also referred to as Tuberous Sclerosis Complex is an autosomal dominant neurocutaneous syndrome that can involve multiple organs such as the brain, heart, kidney, lung, liver, skin and eye. The diagnosis is clinical and most patients are identified during childhood, in the context of a severe epileptic or neuropsychiatric disorder. Here we report a case of TSC diagnosed in an adult woman with dermatological and vascular involvement that were only recognized as manifestations of TSC after the diagnosis of her infant daughter. This case highlights how important it is that physicians recognize the full spectrum of manifestations of TSC, including the most unusual, so not to miss the diagnosis

Responderam ao Questionário de Investigação de Prevalência de Violência Escolar, ao Inventário de Depressão Infantil e à Escala de Engajamento Escolar 396 estudantes de duas escolas públicas. No total, 21 alunos foram agredidos fisicamente por funcionários (AFF. Houve diferenças significativas entre o grupo AFF e o dos que não foram agredidos fisicamente (NAFF. No primeiro houve maior proporção de alunos do sexo feminino, de alunos violentos com os pares e de alunos vítimas de colegas, e maior índice de depressão. Não houve diferenças significativas entre os grupos quanto aos aspectos idade, escolaridade, reprovação e engajamento escolar. Supõe-se que o aluno AFF apresente comportamentos de agressão aos colegas e funcionários da escola e que por isso seja agredido, o que o levaria a continuar sendo agressivo com os outros. Tal hipótese deve ser investigada em estudos futuros.

  4. Design of a costing system and valuation for the production of radiopharmaceutical FDG and the provision of radiology service with PET-CT to Caja Costarricense del Seguro Social, for the Centro de Investigacion en Ciencias Atomicas, Nucleares y Moleculares of the Universidad de Costa Rica

    The cost of the radiopharmaceutical FDG and of the service of diagnostic studies with PET-CT technology are determined through the design of a costing system. The aim has been to provide to the Centro de Investigacion en Ciencias Atomicas, Nucleares y Moleculares (Cicanum), an appropriate decision making as to definition of sale prices in the CCSS-Cicanum Project. This project has arisen of the partnership between the Cicanum and Caja Costarricense del Seguro Social (CCSS), in order to satisfy the needs in the area of oncology; specifically, the acquisition of PET-CT technology. Diagnostic studies can be performed with this technology to detect and measure the evolution of different types of cancer. Additionally, the realization of these studies have required the acquisition of a cyclotron for the production of the radiopharmaceutical called FDG by Cicanum. The theoretical and conceptual aspects relating to atomic, nuclear and molecular sciences are defined, as well as the contribution of the Universidad de Costa Rica for research in these areas and perspectives of costing systems. The administrative-accounting area of Cicanum is described and diagnosed, as well as of the CCSS-Cicanum Project, to know its scope, management and allocation of costs. The situation diagnosed in the administrative-accounting area of Cicanum and the CCSS-Cicanum Project are analyzed, through the tool Swotr (strengths, opportunities, weaknesses, threats and risks). A costing system is elaborated for Cicanum, based on work orders. The system has been developed in a series of electronic work sheets that have allowed to obtain costs associated with the production of the radiopharmaceutical FDG and the rendering of diagnostic services with PET-CT technology to the CCSS, as well as the definition of sales price. As a complement to the above, a master budget is done, which provides a financial vision of the project in its first ten years of operation [es

    Four marine microalgal species (Chlorella autotrophyca, Nannochloropsis gaditana, Tetraiselmis chuii, and Isochrysis aff. galbana) were exposed for 24 h to 1 mg L(-1) dissolved copper and then transferred to fresh medium. After that, a group of 10 neonate rotifers were fed with these four microalgal species. The levels of accumulated copper in cellular concentrations of the microalgae were checked, with the result of around 40% of original concentration, with the exception of I. aff. galbana (25% of original concentration). In all cases, cells with preaccumulated metal caused a delay of 1 or 2 days in populational development of rotifers (increase in "lag phase"). The microalgae that were not fed to rotifers (disposed in parallel series) did not significantly transfer metal to the medium after the first day.

Evaluamos 22 pacientes con diagnóstico anátomo patológico de ASGC. El diagnóstico del tumor se realizó a una media de 10.1 años. Pudimos observar la evolución de NS a ASGC; estos NS se ubicaron adyacentes al agujero de Monro y con el tiempo tuvieron un importante crecimiento con intensa captación de contraste e hidrocefalia. La aceleración en el crecimiento de estos NS y su "transformación" en ASGC se produjo a los 10 años de edad promedio, con un diámetro medio de 9 mm. Ningún NS alejado de los forámenes de Monro evolucionó a ASGC. Quince pacientes (68% fueron operados con síntomas de hipertensión endocraneana. La edad media de la cirugía fue 10.8 años. Seis pacientes presentaron déficit visual. En estos últimos, el diámetro medio mayor del tumor fue 31.5 mm, mayor que los 18.7 mm del grupo de pacientes que no presentó secuela visual. El seguimiento clínico imagenológico periódico de toda lesión subependimaria próxima a los agujeros de Monro, permitiría en etapa presintomática anticipar un tratamiento quirúrgico, que reduciría la incidencia de HTE.

    Full Text Available Although the overall safety profile of bisphosphonates (BP is favorable, adverse effects associated with long-term use have came up during recent years. In this report, a case of bilateral incomplete atypical femoral fracture (AFF due to prolonged BP use was presented. A 69-year-old patient, who has been in surgical menopause for 20 years and was started on BP following vertebral fracture almost 10 years ago, was admitted with thigh pain, which was increased two weeks ago. On physical examination, she had antalgic gait, increased thoracic kyphosis and tenderness to percussion over the thoracolumbar region. Lateral cortical thickness in the subtrochanteric region of both femurs and cortical radiolucency on the left femur were observed on plain radiography. Loss of height in L3 and L4 vertebrae was detected on vertebral radiography. Serum 25-hydroxy vitamin D [25(OHD], parathyroid hormone, alkaline phosphatase and calcium levels, along with osteoporosis markers were all within the normal ranges. As the patient was diagnosed with AFF, BP therapy was terminated and vitamin D-calcium supplementation was continued. Since she did not have severe pain, conservative management (limited weight bearing, using a walking stick was recommended for 3 months. Teriparatide therapy was started and she was discharged with recommendations. AFF, which is a rare disorder, should be kept in mind in patients on long-term BP treatment who are admitted with thigh pain and, necessary interventions should be tailored before the occurrence of complete fracture.

    Full Text Available Braverman and Finkelberg recently proposed the geometric Satake correspondence for the affine Kac-Moody group Gaff [Braverman A., Finkelberg M., arXiv:0711.2083]. They conjecture that intersection cohomology sheaves on the Uhlenbeck compactification of the framed moduli space of Gcpt-instantons on $R^4/Z_r$ correspond to weight spaces of representations of the Langlands dual group $G_{aff}^{vee}$ at level $r$. When $G = SL(l$, the Uhlenbeck compactification is the quiver variety of type $sl(r_{aff}$, and their conjecture follows from the author's earlier result and I. Frenkel's level-rank duality. They further introduce a convolution diagram which conjecturally gives the tensor product multiplicity [Braverman A., Finkelberg M., Private communication, 2008]. In this paper, we develop the theory for the branching in quiver varieties and check this conjecture for $G = SL(l$.

    2007-01-01

    The recent introduction of uninhabited aerial vehicles [UAVs (basically, remotely piloted or autonomous aircraft)] has spawned new developments in autonomous operation and posed new challenges. Automated aerial refueling (AAR) is a capability that will enable UAVs to travel greater distances and loiter longer over targets. NASA Dryden Flight Research Center, in cooperation with the Defense Advanced Research Projects Agency (DARPA), the Naval Air Systems Command (NAVAIR), the Naval Air Force Pacific Fleet, and the Air Force Research Laboratory, rapidly conceived and accomplished an AAR flight research project focused on collecting a unique, high-quality database on the dynamics of the hose and drogue of an aerial refueling system. This flight-derived database would be used to validate mathematical models of the dynamics in support of design and analysis of AAR systems for future UAVs. The project involved the use of two Dryden F/A-18 airplanes and an S-3 hose-drogue refueling store on loan from the Navy. In this year-long project, which was started on October 1, 2002, 583 research maneuvers were completed during 23 flights.

    The micromammal association established in this work is the following: Lagomorpha: Oryctolagus cuniculus; Eulipotyphla: Crocidura cf. russula, cf. Sorex sp., Neomys sp., Soricidae indet. and Talpa sp.; and Rodentia: Eliomys quercinus, Apodemus cf. sylvaticus, Cricetulus (Allocricetus) bursae, Arvicola aff. sapidus, Microtus (Iberomys) brecciensis and Microtus (Terricola duodecimcostatus. This association is characteristic of the Middle Pleistocene. The morphological state of Cricetulus (A.) bursae, Arvicola aff. sapidus and Microtus (I.) brecciensis allows to place it in the advanced, but not final, Middle Pleistocene, which agrees with the numerical data of the site (243–337 ka) that places it in the MIS 8 or 9. The micromammals indicate the predominance of the open spaces with abundant vegetation mainly of herbaceous and bushes but also with some areas with trees. The climate would be of Mediterranean type, similar to the actual or perhaps a little milder and more humid. (Author)

    Forest firefighters are faced with multiple physical and psychological challenges as a result of their duties. Little is known about the determinants of injury among these workers. The Ontario Ministry of Natural Resources (OMNR) Aviation, Forest Fire and Emergency Services (AFFES) records detailed information on two mutually exclusive types of workplace injury: First aid (self-reported) and Workplace Safety Insurance Board (WSIB, i.e. received medical attention). To identify the contributions of physical and psychological factors on the likelihood of injury among forest firefighters. Participants were male and female forest firefighters aged between 18 and 65. Data were collected using two self-administered instruments: The NEO Personality Inventory and the Job Stress Survey. Secondary data were collected from the OMNR AFFES and data were analysed by way of multivariate statistical procedures. There were 252 participants. Those who were older, had a history of injury, had high scores for the personality construct of Neuroticism or low scores for the Openness construct were significantly more likely to incur a first aid injury, while those with high experience levels were significantly less likely to incur injury (P First aid and WSIB injuries in the OMNR AFFES were quite distinct phenomena and different factors need consideration in their prediction. It is recommended that managers and decision-makers in this field consider factors such as job stress, personality and the prior occurrence of injuries in their assessment of risk. © The Author 2014.

  19. E-Orbit Functions

    Directory of Open Access Journals (Sweden)

    Jiri Patera

    2008-01-01

    Full Text Available We review and further develop the theory of $E$-orbit functions. They are functions on the Euclidean space $E_n$ obtained from the multivariate exponential function by symmetrization by means of an even part $W_{e}$ of a Weyl group $W$, corresponding to a Coxeter-Dynkin diagram. Properties of such functions are described. They are closely related to symmetric and antisymmetric orbit functions which are received from exponential functions by symmetrization and antisymmetrization procedure by means of a Weyl group $W$. The $E$-orbit functions, determined by integral parameters, are invariant withrespect to even part $W^{aff}_{e}$ of the affine Weyl group corresponding to $W$. The $E$-orbit functions determine a symmetrized Fourier transform, where these functions serve as a kernel of the transform. They also determine a transform on a finite set of points of the fundamental domain $F^{e}$ of the group $W^{aff}_{e}$ (the discrete $E$-orbit function transform.

    This study aims to investigate the effect of soy lecithin on the total cholesterol content, the fatty acid composition and carcass characteristics in the Longissimus dorsi in Hanwoo steers. Hanwoo steers (24 head) were fed two diets: Control (CON) (concentrate + alcohol-fermented feed (AFF)) and soy lecithin treatment (CON + soy lecithin at 0.5% of the AFF). Soy lecithin treatment increased average daily gain, serum concentrations of triglyceride, total cholesterol and high-density lipoprotein-cholesterol in the blood. A lower cholesterol concentration was found in the Longissimus dorsi for the soy lecithin diet compared to the CON diet. With respect to the marbling score and quality grade of Longissimus dorsi, soy lecithin supplementation significantly increased the C20:5n3, C22:4 and polyunsaturated fatty acids contents compared to the CON diet. Soy lecithin supplementation would alter the total cholesterol content, polyunsaturated fatty acid profile and meat quality of Longissimus dorsi. © 2016 Japanese Society of Animal Science.

    2018-06-01

    In the Wakatobi region of Indonesia, a prolonged period of elevated water temperature in 2016 caused extensive coral bleaching and mortality. Unusually, bleaching was also observed in the bioeroding sponge Cliona aff. viridis, with affected sponges expelling 99% of their Symbiodinium. Bleaching surveys of C. aff. viridis were conducted 6 weeks apart, coinciding with a 0.8 °C drop in water temperature. Over this period, bleaching prevalence dropped from 73.9% (± 9.9 SE) to 25.7% (± 5.8 SE), and bleaching severity dropped from 25.95% (± 4.5 SE) to 11.54% (± 1.9 SE) of sponge tissue. Over the same period, monitored bleached sponges showed an 81% drop in bleaching severity, but also a 13% reduction in overall sponge size. Our results show that while the clionaid- Symbiodinium relationship is susceptible to break down under thermal stress, rapid recovery can occur, although incurring some partial host mortality.

    2014-10-01

    Full Text Available Context:The biological potential of lichens has been documented through their use in traditional medicine. Secondary lichen metabolites exert a wide variety of biological actions, including their use as antioxidants. Aims:To evaluate the antioxidant activity, total phenol content, and flavonoids of four lichen fungal taxa collected in Mérida (Venezuela, and statistically evaluate the correlation between the antioxidant activity and the amount of phenols and flavonoids in the samples. Methods: Extracts were prepared with water, ethanol and dichloromethane from Cladonia aff. rappii, Cora aff. glabrata, Peltigera laciniata and Thamnolia vermicularis. The antioxidant capacity assessment was determined using DPPH• radical method and reducing power, with ascorbic acid as control. Total phenols were determined by means of the Folin-Ciocalteu method with gallic acid. Total flavonoids were estimated according to the modified Dowd method, using quercetin as standard. Results:The ethanolic extracts of the tested lichens showed the highest scavenging activity and reducing power compared to water and dichloromethane extracts at 4 mg/mL. The highest antiradical power value was found in ethanolic extract of Peltigera laciniata (2.28 mL/mgand the lowest in dichloromethane extract of Cora aff. glabrata (0.30 mL/mg. The correlation between antioxidant activity and total phenolic content was moderate. The flavonoids content of ethanolic extracts was highly significant but negative (p < 0.05. There was good correlation in dichloromethane extracts. The ethanolic extract of P. laciniata exhibited the highest antiradical activity despite showing the lowest flavonoid content. Conclusions: The ethanolic extracts of lichens tested showed to have the higher antioxidant activity and may be used as natural sources of new antioxidants.

  9. Evaluating the potential of housekeeping genes, rRNAs, snRNAs, microRNAs and circRNAs as reference genes for the estimation of PMI.

    The precise estimation of postmortem interval (PMI) is a critical step in death investigation of forensic cases. Detecting the degradation of RNA in tissues by real time quantitative polymerase chain reaction (RT-qPCR) technology provides a new theoretical basis for estimation of PMI. However, most commonly used reference genes degrade over time, while previous studies seldom consider this when selecting suitable reference genes for the estimation of PMI. Studies have shown microRNAs (miRNAs) are very stable and circular RNAs (circRNAs) have recently emerged as a novel class of RNAs with high stability. We aimed to evaluate the stability of the two kinds of RNAs and normal reference genes using geNorm and NormFinder algorithms to identify tissue-specific reference genes for PMI estimation. The content of candidate RNAs from mouse heart, liver and skeletal muscle tissues were dynamically examined in 8 consecutive days after death. Among the 11 candidate genes (β-actin, Gapdh, Rps18, 5S, 18S, U6, miR-133a, miR-122, circ-AFF1, LC-Ogdh and LC-LRP6), the following genes showed prioritized stability: miR-122, miR-133a and 18S in heart tissues; LC-Ogdh, circ-AFF1 and miR-122 in liver tissues; and miR-133a, circ-AFF1 and LC-LRP6 in skeletal muscle tissues. Our results suggested that miRNAs and circRNAs were more stable as reference genes than other kinds of RNAs regarding PMI estimation. The appropriate internal control genes were not completely the same across tissue types.

    In Mexico, the Upper Jurassic to lowermost Cretaceous La Casita and coeval La Caja and La Pimienta formations are well-known for their abundant and well-preserved marine vertebrates and invertebrates. The latter include conspicuous inoceramid bivalves of the genus Anopaea not formally described previously from Mexico. Anopaea bassei (Lecolle de Cantú, 1967), Anopaea cf. stoliczkai (Holdhaus, 1913), Anopaea cf. callistoensis Crame and Kelly, 1995 and Anopaea sp. are rare constituents in distinctive Tithonian-lower Berriasian levels of the La Caja Formation and one Tithonian horizon of the La Pimienta Formation. Anopaea bassei was previously documented from the Tithonian of central Mexico and Cuba, while most other members of Anopaea described here are only known from southern high latitudes. The Mexican assemblage also includes taxa which closely resemble Anopaea stoliczkai from the Tithonian of India, Indonesia and the Antarctic Peninsula, and Anopaea callistoensis from the late Tithonian to ?early Berriasian of the Antarctic Peninsula. Our new data expand the palaeogeographical distribution of the high latitude Anopaea to the Gulf of Mexico region and substantiate faunal exchange, in the Late Jurassic-earliest Cretaceous, between Mexico and the Antarctic Realm.

    Full Text Available There exists an abysm between market prices and traditional valuation approaches such as Discounted Cash Flows (DCF, a fact that neither academics nor practitioners could continue ignoring. Recently, a complementary approach has taken a foothold into the valuation world. Building on the DCF approach yet going further in the sense of incorporating flexibility in management investment decisions, and taking advantage of the advances in option pricing theory, the real options approach (ROA has become the alternative to capital budgeting and, lately, to corporate valuation. Empirical evidence shows that ROA explains actual prices better than DCF approaches and nowadays there is no question that from a theoretical point of view, ROA is a much more appealing concept than passive NPV. However, its acceptance by practitioners has been very slow due to the complexity of real options pricing.Existe un abismo entre precios de Mercado y la valoración estimada por métodos tradicionales tales como Flujos de Caja Descontados, un hecho que ni académicos ni practicantes pueden continuar ignorando. Recientemente, una metodología complementaria ha tomado gran fuerza. Partiendo de los Flujos de Caja Descontados, pero incorporando flexibilidad en las decisiones de inversión y aprovechando los avances en la teoría de valoración de opciones, el enfoque de opciones reales (ROA se ha convertido en la alternativa para presupuestación de capital y valoración de empresas. La evidencia empírica muestra que ROA explica los precios de mercado mejor que los enfoques basados en flujos de caja descontados y, hoy en día, no hay discusión de que es más atractivo desde un punto de vista teórico; sin embargo, su utilización en la práctica ha sido muy limitada debido a las dificultades que presenta la valoración de las opciones reales.

    Full Text Available Introducción: los tumores primarios cardiacos son raros durante la infancia y en su mayoría benignos, siendo los rabdomiomas los más comunes, asociándose en más del 60% de los casos con esclerosis tuberosa. La mayoría de ellos tienden a involucionar, pero algunos, según su localización y manifestaciones clínicas, requerirán tratamiento quirúrgico. Caso clínico: recién nacido del sexo femenino, hija de madre de 34 años. Nace producto de cesárea iterada a las 40 semanas, Apgar 9-9 y peso al nacer 2800 gramos. Tuvo seguimiento por Genética Clínica durante el embarazo por detectarse en ultrasonido prenatal la presencia de tumoración intracardiaca, la cual se confirma al realizar ecografía postnatal, con un área tumoral de 3,5mm. Se diagnostica Rabdomioma intracardiaco que no obstruye el tracto de salida, con seguimiento clínico y ecocardiográfico mensual y evolución favorable. Conclusiones: los tumores cardiacos fetales son extraordinariamente raros. Se pueden diagnosticar por ecografía desde la vida intrauterina. La actitud recomendada es expectante por la posibilidad de regresión espontánea, excepto en aquellos casos con repercusión clínica. En el seguimiento se debe descartar la presencia de esclerosis tuberosa por su elevada asociación con esta entidad.

Apesar do aumento significativo da demanda de algumas frutas exóticas nos últimos anos, o volume total ainda é pequeno em relação ao volume total das demais frutas. Em 2012, na Companhia de Entrepostos e Armazéns Gerais de Säo Paulo - CEAGESP, as frutas exóticas representaram 0,65% do volume total de frutas comercializadas e 2,09% do volume financeiro do setor de frutas. A oferta de algumas frutas exóticas na CEAGESP teve crescimentos surpreendentes nos últimos 5 anos, como foi o caso da lichia, romä, mangostäo, pitaya, physalis e das frutas vermelhas- amora e framboesa.

    Bedeian, A G; Touliatos, J

    1978-05-01

    Acknowledging the need for additional research on work-related motives and self-esteem in American women, this study investigated the hypothesis that women with a favorable self-esteem would score high in n Ach, in Pow, and n Auto, whereas women with a less favorable self-esteem would score high in n Aff, n Agg, and n Def. Eighty-five female college students completed Gough and Heilbrun's Adjective Check List and Form B of the Coopersmith Self-Esteem Inventory. Data were analyzed by means of chi square tests in conjunction with the coefficient of association asymmetric lambda. The results indicated that, as predicted, women with a favorable self-esteem scored high in n Ach (p less than .001) and n Pow (p less than .001), while contrary to expectation, they also scored high in n Aff (p less than .05). All other relationships were found to be nonreliable. These findings were interpreted as stressing the importance of the relationship between self-esteem and work-related motives in women.

    The antifungal activity of the three lichens extracts was evaluated in this work. Extracts from Leptogium cyanescens, Physcia americana and Pyxine aff. cocoes were collected extracts from the lichens thallus in 2009 in areas fromo the Jardin Botanico Cienfuego, Cuba. The fungicide activity was evaluated against phytopathogens fungi of potato: Rhizoctonia solani and Phytophthora nicotianae var parasitica. The study was conducted from 2009 to 2011. The compounds were extracted with acetone, concentrated by rotoevaporation, and evaluated at concentrated of 0,01 and 0,07% in potato dextrose agar (PDA) culture medium; stock solution was made of 5% dimethilsufoxide. These extracts were classified by their toxicity as: toxic, slight and moderately toxic and harmless. The extracts from P. americana of 0,07% inhibited P. nicotianae 100%, and it showed values over 50% for R. solani. L. cyanescens only showed fungicide activity in both phytopathogens at the maximum concentration studied; similar results were obtained with the extract from P. aff. cocoes. The lichens extracts were classified as lightly toxic at the maximun concentration, and harmless at the minimum concentration. (author) [es

No geographic variation was detected in O. occipitalis but there is marked geographic variation in color pattern and scutellation for the widely distributed O. petola. Recognition of subspecies within O. petola is possible but appears to obscure more than it illuminates. The snake previously reported as O. melanogenys or O. aff. melanogenys is diagnosed as a previously unrecognized species.Cuatro especies del género Oxyrhopus se encuentran en Colombia.

    A Centro de Produccion de Radio Farmacos de Aplicaciones en Sistemas PET will be implemented in Costa Rica. Universidad de Costa Rica will have technology that allows you to help with early detection of tumors in a much more rapid and painless. The development of PET technology in the Caja Costarricense de Seguro Social and private health sector, has been delayed by the lack of definition in the supply of radiopharmaceuticals; due to the high cost of a cyclotron system and ensuring its profitability, being here where the Universidad de Costa Rica come to play a key role as an impartial figure in the scheme of national implementation. Therefore, a bilateral agreement is exposed for the daily supply of radiopharmaceuticals in place at a cost inversely proportional to the volume of consumption and enabling financial sustainability of the project. This agreement must be established between the Universidad de Costa Rica and the Caja Costarricense de Seguro Social, and then seek expansion of marketing with the private sector nationwide. A SWOT (Strengths, Weaknesses, Opportunities and Threats) is developed on the project. Also, the geographical location of the project facilities is showed, the architecture of the project cost without operations. Finally, the architectural design of the building is presented [es

    Full Text Available The ability of nodal segments of Ipomoea batatas to differentiate shoots and roots was evaluated after gamma irradiation. Shoot differentiation was less sensitive to irradiation than roots. However, at 90 Gy, no shoot was able to regenerate a new plant; in contrast 76 % of the roots from irradiated nodal segments continued to grow. The gamma radiation also induced changes in electrophoretic profiles of peroxidases of storage roots. Plants originated from irradiated storage roots presented changes in leaf peroxidase profiles very similar to those produced by leaves directly irradiated. The peroxidase profile of absorbent roots from irradiated storage roots was different from that obtained from directly irradiated absorbent roots.A capacidade de Ipomoea batatas diferenciar parte aérea e raízes foi avaliada após irradiação com raios gama. A diferenciação da parte aérea foi menos sensível que a das raízes. Contudo, na dose de 90 Gy nenhum broto diferenciado regenerou planta, enquanto 76 % das raízes diferenciadas dos segmentos nodais irradiados manteve o crescimento. A radiação também induziu mudanças no perfil elotroforético de isoperoxidases. Plantas originadas de raízes tuberosas irradiadas apresentaram alteração no perfil de isoperoxidases foliares semelhantes ao perfil de folhas diretamente irradiadas. O perfil de isoperoxidases de raízes absorventes irradiadas diretamente não apresentou o mesmo padrão do perfil das raízes absorventes desenvolvidas de raízes tuberosas irradiadas.

    Hypostomus is a diverse group with unclear aspects regarding its biology, including the mechanisms that led to chromosome diversification within the group. Fluorescence in situ hybridization (FISH) with 5S and 18S rDNA probes was performed on ten Hypostomini species. Hypostomus faveolus, H. cochliodon, H. albopunctatus, H. aff. paulinus, and H. topavae had only one chromosome pair with 18S rDNA sites, while H. ancistroides, H. commersoni, H. hermanni, H. regani, and H. strigaticeps had multiple 18S rDNA sites. Regarding the 5S rDNA genes, H. ancistroides, H. regani, H. albopunctatus, H. aff. paulinus, and H. topavae had 5S rDNA sites on only one chromosome pair and H. faveolus, H. cochliodon, H. commersoni, H. hermanni, and H. strigaticeps had multiple 5S rDNA sites. Most species had 18S rDNA sites in the telomeric region of the chromosomes. All species but H. cochliodon had 5S rDNA in the centromeric/pericentromeric region of one metacentric pair. Obtained results are discussed based on existent phylogenies for the genus, with comments on possible dispersion mechanisms to justify the variability of the rDNA sites in Hypostomus.

    Marine sponges usually constitute the most diverse group of the benthic community in coral reefs. Although they are reasonably well studied at the northern Gulf of Mexico (GMx), the southern GMx is poorly known and lacks records from many major reef systems that lie off the Mexican coast. The present taxonomic study is the first sponge account from Alacranes reef, the largest coral reef system in the GMx, and from the shallow reef banks of Sisal, both in the northwest Yucatan Peninsula. The 19 species herein described represent the first sponge fauna records from these reefs. Among these, seven species represent new record for GMx: Erylus formosus, Cliona flavifodina, Spirastrella aff. mollis, Strongylacidon bermuda, Topsentia bahamensis, Agelas tubulata and Chelonaplysilla aff. erecta. Twelve species are new records for the Southern GMx: Erylus trisphaerus, Cliona amplicavata, Chondrilla caribensis, Halichondria lutea, Hymeniacidon caerulea, Axinella corrugata, Dragmacidon reticulatum, Chalinula molitba, Amphimedon caribica, A. complanata, Hyatella cavernosa and Dysidea variabilis. Additionally, a redescription of Erylus trisphaerus is presented which had not been reviewed since its original description in 1953 off Western Florida, except that it was listed for north La Habana, Cuba.

    The purpose of the current study was to evaluate the cytogenetic findings in 1,057 children with acute lymphoblastic leukemia (ALL) referred to the cytogenetics laboratory at the Hospital de Pediatría Dr. Juan P. Garrahan, between 1991 and 2014. Chromosomal abnormalities were evaluated by G-banding and FISH. Since December 2002, RT-PCR determinations were systematically carried out for BCR-ABL1, KMT2A-AFF1, ETV6-RUNX1, and TCF3-PBX1 rearrangements in children, adding KMT2A-MLLT3 and KMT2A-MLLT1 in infants. The percentage of abnormalities detected by cytogenetics was 70.1%. Four novel abnormalities, t(2;8)(p11.2;p22), inv(4)(p16q25), t(1;7)(q25;q32), and t(5;6)(q21;q21), were found in this cohort. We compared cytogenetic and RT-PCR results for BCR-ABL1, KMT2A-AFF1 and TCF3-PBX1 rearrangements in 497 children evaluated by both methods. The results were highly concordant (p cytogenetic findings in children with ALL reported in Argentina. PMID:26648836

    Andean roots and tubers are underexploited crops; many contain compounds beneficial to health, so a greater knowledge of their properties is important for encouraging their consumption. The aim of this work was to study the content of bioactive compounds of yacon and oca and their effect on intestinal health using as a model rats of the Wistar strain. Two varieties of ocas (Overa and Rosada) and yacon, which contain significant amounts of fructooligosaccharides and phenolic compounds, were chosen. Rats of the Wistar strain were fed for two months with diets containing these foods in amounts sufficient to provide 8% of fiber. A significant decrease in pH values and an increment in lactobacilli and bifidobacteria counts in the cecum of rats fed with inulin, oca Rosada and Overa were observed; there was no significant decrease in enterobacteriaceae and enterococci counts. The cecum antioxidant activity was incremented in rats fed with the experimental foods with respect to the control diets. The components of dietary fiber and phenolic compound contents in yacon and oca produce effects that contribute to the intestinal health of the experimental animals.

    Full Text Available The construction of reservoirs is considered an important source of impacts on the fish fauna, severely altering the structure of the assemblage. This paper aimed to describe the structure of the fish assemblage of the Goioerê River, determining its longitudinal distribution and patterns of species dominance. The evaluation of its longitudinal variation in the diversity and abundance of the fish assemblage was conducted in July and October 2004 and January and May 2005. The collections were carried out near the headwaters (Gurucaia, middle stretch (Olaria, just above the falls (Paiquerê and downstream (Foz. Forty-four species were captured. The Gurucaia fish assemblages differed significantly from Olaria, Paiquerê and Foz. The Olaria assemblages differed significantly from the Foz. Gurucaia showed the lowest diversity and abundance of species. Astyanax aff paranae Eigenmann,1914 (78% of the total was found to be dominant at this site. Almost the same species richness was found at Olaria and Paiquerê, although Olaria had the greatest abundance of individuals. Astyanax aff paranae, Cyphocharax modestus (Fernández-Yépez, 1948 and Astyanax altiparanae Garutti & Britski, 2000 were the top three dominants and comprised over 71% of the total number of fish caught. At Paiquerê, Astyanax altiparanae, Hypostomus aff ancistroides (Ihering, 1911 and Loricariichthys platymetopon Isbrücker & Nijssen, 1979 composed 58% of the catches. Thirty-one species were recorded at Foz, which presented the greatest richness. The most abundant species were Apareiodon affinis (Steindachner, 1879, Galeocharax knerii (Steindachner, 1879 and A.altiparanae, which contributed to 50% of the total catches in this environment.These results record the fish biodiversity and how the community is longitudinally structured in the Goioerê River, and also demonstrate how this type of evaluation is important to understanding the fish community patterns and finding solutions to

    Full Text Available Winter cereals are mainly used for human and animal nutrition and several studies are now exploring their potential as conserved forage (hay and silage. Among the winter cereal species available for cultivation in the south of Brazil, which is major winter cereals producer in the country, the wheat cv. BRS Umbu has attracted special attention. However, few studies have investigated the potential of this cultivar for silage production. The aim of this study was to evaluate the production and quality of silage from the dual-purpose wheat, BRS Umbu, subjected to different cut managements treatments: T1 - without cut (control, T2 - one cut and T3 - two cuts. Each plot represented an experimental unit in a randomized block design, with 5 replicates per treatment. Two representative samples were collected from each plot to determine morphological segmentation (stem, leaf and ear and dry matter (DM content of the whole plant and its morphological components. At the time of opening of the silos, food chemical analysis and pH determination were performed. Forage mass production decreased by 26.88% and 67.82%, respectively, with one and two cuts, compared to control. The DM content of the ensiled plant was 49.9 g kg-1 for the control, 54.7 g kg-1 with one cut and 63.2 g kg-1 with two cuts, at the time of ensiling. Management cuts changed the morphological components of the plants, with a lower proportion of stem (28% in plants subjected to two cuts. The control treatment showed fewer leaves in ensiled plant (9.6% and intermediate amount of stalk (52.8%, and was significantly different (p 0.05 was observed for mineral matter (MM, crude protein (CP and hemicellulose (HEM between the different cutting regimens. However, neutral detergent fiber (NDF and acid detergent fiber (ADF decreased (p < 0.05 as the number of cuts increased.

    Full Text Available In traditional Andean agrosystems, three minor tuber crop species are of regional or local importance: oca (Oxalis tuberosa Molina, ulluco (Ullucus tuberosus Caldas and mashua (Tropaeolum tuberosum Ruiz and Pav.. Genetic diversity within these species is very large and could result from the high ecological and cultural variability that characterizes the Andean area. Nowadays, many anthropic or ecological factors cause the loss of diversity and contribute to genetic erosion. The development of conservation strategies for genetic resources of Andean tubers, in situ as well as ex situ, includes a better knowledge of diversity in addition to the study of Andean farming strategies linked to this genetic diversity.

    Full Text Available Bee products have been used empirically for centuries, especially for the treatment of respiratory diseases. The present study evaluated the effect of treatment with a propolis hydroalcoholic extract (PHE produced by Scaptotrigona aff. postica stingless bee in a murine asthma model. BALB/c mice were immunized twice with ovalbumin (OVA subcutaneously. After 14 days, they were intranasally challenged with OVA. Groups P50 and P200 received PHE by gavage at doses of 50 and 200 mg/kg, respectively. The DEXA group was treated with intraperitoneal injection of dexamethasone. The OVA group received only water. The mice were treated daily for two weeks and then they were immunized a second time with intranasal OVA. The treatment with PHE decreased the cell number in the bronchoalveolar fluid (BAL. Histological analysis showed reduced peribronchovascular inflammation after treatment with PHE especially the infiltration of polymorphonuclear cells. In addition, the concentration of interferon-γ (IFN-γ in the serum was decreased. These results were similar to those obtained with dexamethasone. Treatment with S. aff postica propolis reduced the pathology associated with murine asthma due an inhibition of inflammatory cells migration to the alveolar space and the systemic progression of the allergic inflammation.

    2012-12-01

    Full Text Available In this paper we discuss archival storage container formats from the point of view of digital curation and preservation, an aspect of preservation overlooked by most other studies. Considering established approaches to data management as our jumping off point, we selected seven container format attributes that are core to the long term accessibility of digital materials. We have labeled these core preservation attributes. These attributes are then used as evaluation criteria to compare storage container formats belonging to five common categories: formats for archiving selected content (e.g. tar, WARC, disk image formats that capture data for recovery or installation (partimage, dd raw image, these two types combined with a selected compression algorithm (e.g. tar+gzip, formats that combine packing and compression (e.g. 7-zip, and forensic file formats for data analysis in criminal investigations (e.g. aff – Advanced Forensic File format. We present a general discussion of the storage container format landscape in terms of the attributes we discuss, and make a direct comparison between the three most promising archival formats: tar, WARC, and aff. We conclude by suggesting the next steps to take the research forward and to validate the observations we have made.

    Sedimentary facies from the Candeleros Formation (Rio Limay Subgroup), cropping out at the El Escondido creek, at the Ezequiel Ramos Mexia dam, are analyzed and interpreted in this paper. A sedimentological detailed section was measured to get the main goal of this paper which is the sedimentary paleoenvironment. The outcroppings were pictured and a section was measured, geometries and espacial relation between them were analyzed. Eight lithofacies were identified which are: coarse sandstone facies (Se), sandstones (Sm, St, Sp, Sh t Sr), siltstones and shales (Fl and Fr). These lithofacies were agrupated into eight facies associations (FA). AFA constitutes the registration of multiepisodic events of sheet floods; AFB, C and D are product of the depositation in a braided channel belt, AFE represents units of lateral accretion, AFF is assigned deposits of crevasse splay and AFG and H are assigned to plain of flood. The distribution of these associations in the column defines an terminal fan paleoenvironment where is represented of base to top: distal (AFA, B and G) and proximal area (AFD and G) of the distributary plain; zone of feeding of the system (AFC, And, F and G), media-proximal distributary plain (AFD and F), proximal distributary plain (AFC, And, F and G); and flood basin (AFF, G and H) [es

    Full Text Available Leaf litterfall contributes significantly to carbon fluxes in forests. A crucial open question for the sustainability of mountain forests is how climate change will affect this and other carbon fluxes (eg photosynthesis and respiration. Leaf litterfall and decomposition of Polylepis reticulata, an endemic species of the Andes, were analyzed during a period of 1 year at 6 experimental plots located in the Andean páramo between 3700 and 3900 m above sea level in Cajas National Park, Ecuador. Litterfall was collected in each plot using 5 randomly distributed traps. Every trap had a 40-cm diameter (0.125 m2 and was suspended 0.8 to 1.0 m above the ground. The decomposition rate of the leaf litter was analyzed using litter bags. Eighteen bags with approximately 20 g of dry litter were placed in the litter layer in each experimental plot and collected 30, 60, 90, 150, 210, 300, and 365 days after they were installed. The mean annual litterfall recorded was 3.77 Mg ha−1, representing 51% of the leaf biomass present in the canopy, so the leaf life span of P. reticulata in Cajas National Park is 1.98 years. Litterfall occurred all year, with no significant seasonal pattern. The mean decomposition rate (k obtained for this study period was 0.38 year−1. This study contributes to the information gap on litterfall and decomposition in natural forests located at the highest elevations in the world.

  18. Cytotoxic and Apoptosis-Inducing Activity of Plants from the Family Asparagaceae in Relation to Human Alveolar Adenocarcinoma Cells

    Directory of Open Access Journals (Sweden)

    2016-06-01

    Full Text Available Cancer is known as the second major mortality cause. The number of new cases is increasing every year. Thus, it is urgent for scientists to search for alternative drugs with selective antitumor action and minimal side effects. It is known that some plant metabolites exhibit antioxidant, cytotoxic, and antitumor activity, while at the same time being less toxic than modern allopathic drugs. In this work, we have investigated the cytotoxic and apoptosis-inducing effects of extracts obtained from plants of the family Asparagaceae on A549 human lung adenocarcinoma cells. The analysis has been performed using flow cytofluorometry. If extracts showed cytotoxicity, the apoptosis-inducing action has been evaluated at the concentration of 50 μg/mL; in other cases, the analyzed concentration range was 50–300 μg/mL. On the basis of the experiments carried out, the following conclusions have been made. Extracts of the leaves and rhizomes of Sansevieria cylindrica and Sansevieria trifasciata do not possess antitumor activity. Extracts of the leaves of Polianthes tuberosa and Furcraea gigantea, which were cytotoxic at high concentrations, cause cell death at 50 μg/mL in the amount of 21.35 ± 1.86 and 15.6 ± 3.23, respectively. Extracts of Polianthes tuberosa bulbs and Yucca filamentosa leaves are able to induce apoptosis at higher concentrations. When the concentration reaches 100 μg/mL, the proportion of apoptotic cells for these plants is 45.76 ± 1.34 and 11.33 ± 0.07, respectively. The number of dead cells at the concentration of 300 μg/mL increased up to 73.33 ± 3.05 and 81.75 ± 4.07. The results have great importance for development of new drugs based on metabolites from these plant extracts.

The karyotype description of the majority of the species was based on chromosome number and morphology, condensation pattern of prophase chromosomes as well as interphase nuclear structure. In five species (Cereus jamacaru, 2n=22; Clitoria fairchildiana, 2n=22; Eugenia luschnathiana, 2n=22; Licania tomentosa, 2n=22; and Spondias tuberosa, n=16 the chromosome number is reported here for the first time. In the case of Licania tomentosa, this is also the first report for the genus. Among the other 28 species, three (Cecropia cf. palmata, 2n=26; Crinum erubescens, 2n=70; and Schinus terebentifolius, 2n=28 showed chromosome numbers different from what has previously been reported.

    Full Text Available Dando continuidade ao levantamento dos táxons de Marantaceae ocorrentes no Brasil, propõe-se novidades taxonômicas e nomenclaturais envolvendo algumas espécies de Marantaceae descritas e ilustradas na Flora Fluminensis de Frei José Mariano da Conceição Vellozo. Maranta monophylla, M. prolifera e M. tuberosa são circunscritas aqui a partir das informações morfológicas e fitogeográficas contidas nas descrições e nos comentários existentes nas obras originais, além da análise das estampas publicadas em contribuições subseqüentes e que ilustram com detalhamento as espécies. A partir dos dados coligidos e da comparação com coleções recentes e tipos nomenclaturais é proposta uma nova combinação, dada a necessidade de se transferir M. prolifera para o gênero Calathea. São propostos como sinônimos algumas espécies de Calathea comumente citadas nos levantamentos florísticos realizados no domínio da Floresta Atlântica.To continue the survey on Marantaceae taxa being carried out in Brazil, new taxonomic and nomenclatural proposals are made involving some species of Marantaceae described and illustrated in Flora Fluminensis by Friar José Mariano da Conceição Vellozo. Maranta monophylla, M prolifera and M. tuberosa are circumscribed here from morphologic and phytogeographic information contained in descriptions and commentaries from Vellozo's originals, as well as from analysis of prints which were published subsequently that illustrate the species in detail. From the gathered data and the comparison with recent collections and nomenclatural types, a new combination is proposed, due to the necessity of transferring M. prolifera to the genus Calathea. Some Calathea species commonly cited in floristic surveys at the Atlantic Forest are proposed as synonyms.

  19. The gsdf gene locus harbors evolutionary conserved and clustered genes preferentially expressed in fish previtellogenic oocytes.

    Science.gov (United States)

    Gautier, Aude; Le Gac, Florence; Lareyre, Jean-Jacques

    2011-02-01

    The gonadal soma-derived factor (GSDF) belongs to the transforming growth factor-β superfamily and is conserved in teleostean fish species. Gsdf is specifically expressed in the gonads, and gene expression is restricted to the granulosa and Sertoli cells in trout and medaka. The gsdf gene expression is correlated to early testis differentiation in medaka and was shown to stimulate primordial germ cell and spermatogonia proliferation in trout. In the present study, we show that the gsdf gene localizes to a syntenic chromosomal fragment conserved among vertebrates although no gsdf-related gene is detected on the corresponding genomic region in tetrapods. We demonstrate using quantitative RT-PCR that most of the genes localized in the synteny are specifically expressed in medaka gonads. Gsdf is the only gene of the synteny with a much higher expression in the testis compared to the ovary. In contrast, gene expression pattern analysis of the gsdf surrounding genes (nup54, aff1, klhl8, sdad1, and ptpn13) indicates that these genes are preferentially expressed in the female gonads. The tissue distribution of these genes is highly similar in medaka and zebrafish, two teleostean species that have diverged more than 110 million years ago. The cellular localization of these genes was determined in medaka gonads using the whole-mount in situ hybridization technique. We confirm that gsdf gene expression is restricted to Sertoli and granulosa cells in contact with the premeiotic and meiotic cells. The nup54 gene is expressed in spermatocytes and previtellogenic oocytes. Transcripts corresponding to the ovary-specific genes (aff1, klhl8, and sdad1) are detected only in previtellogenic oocytes. No expression was detected in the gonocytes in 10 dpf embryos. In conclusion, we show that the gsdf gene localizes to a syntenic chromosomal fragment harboring evolutionary conserved genes in vertebrates. These genes are preferentially expressed in previtelloogenic oocytes, and thus, they

    2012-01-01

    The aim of this study was to compare 3 different available methods for estimating left ventricular end-diastolic pressure (LVEDP) noninvasively in patients with coronary artery disease and preserved left ventricular ejection fraction (EF). We used 3 equations for noninvasive estimation of LVEDP: The equation of Mulvagh et al., LVEDP(1) = 46 - 0.22 (IVRT) - 0.10 (AFF) - 0.03 (DT) - (2 ÷ E/A) + 0.05 MAR; the equation of Stork et al., LVEDP(2) = 1.06 + 15.15 × Ai/Ei; and the equation of Abd-El-Aziz, LVEDP(3) = [0.54 (MABP) × (1 - EF)] - 2.23. ( A, A-wave velocity; AFF, atrial filling fraction; Ai, time velocity integral of A wave; DT, deceleration time; E, E-wave velocity; Ei, time velocity integral of E wave; IVRT, isovolumic relaxation time; MABP, mean arterial blood pressure; MAR, time from termination of mitral flow to the electrocardiographic R wave; Ti, time velocity integral of total wave.) LVEDP measured by catheterization was correlated with LVEDP(1) (r = 0.52, P Aziz, LVEDP = [0.54 MABP × (1 - EF)] - 2.23, appears to be the most accurate, reliable, and easily applied method for estimating LVEDP noninvasively in patients with preserved left ventricular ejection fraction and an LVEDP < 20 mm Hg.

    Full Text Available We determined in this study the habitat preferences of seven native fish species in a regulated river in Southeastern Brazil. We tested the hypothesis that fishes differ in habitat preference and that they use stretches of the river differing in hydraulic characteristics and substrate type. We surveyed fishes in four 1-km long river stretches encompassing different habitat traits, where we also measured water depth, velocity, and substrate type. We investigated preference patterns of four Siluriformes (Loricariichthys castaneus, Hoplosternum littorale, Pimelodus maculatus, and Trachelyopterus striatulus and three Characiformes (Astyanax aff. bimaculatus, Oligosarcus hepsetus, and Hoplias malabaricus, representing approximately 70% of the total number of fishes and 64% of the total biomass. We classified fishes into four habitat guilds: (1 a slow-flowing water guild that occupied mud-sand substrate, composed of two Siluriformes in either shallow ( 8 m, L. castaneus waters; (2 a run-dwelling guild that occurs in deep backwaters with clay-mud substrate, composed of the Characiformes A. aff. bimaculatus and O. hepsetus; (3 a run-dwelling guild that occurs in sandy and shallow substrate, composed of T. striatulus; and (4 a fast-flowing guild that occurs primarily along shorelines with shallow mud bottoms, composed of H. malabaricus and P. maculatus. Our hypothesis was confirmed, as different habitat preferences by fishes appear to occur in this regulated river.

  12. Efectos de la crisis financiera sobre la innovación en la reorganización de los sistemas bancarios: los sistemas institucionales de protección en las entidades financieras de ámbito territorial

    Full Text Available La crisis financiera internacional ha actuado como catalizador de un profundo proceso de cambio en la supervisión financiera y en su modelo de negocio. Este trabajo pretende analizar los recientes procesos de reorganización bancaria iniciados en las entidades de ámbito territorial (cajas de ahorros y cooperativas de crédito que, a su vez, son identificadas como entidades financieras de economía social. Su especial arraigo territorial ha llevado a la posibilidad de aplicación de una innovadora fórmula legal propuesta por la Unión Europea denominada Sistema Institucional de Protección (SIP, surgida meses antes del estallido de la crisis financiera internacional. Con este propósito, se contempla, primeramente, el entorno configurado por las consecuencias de la crisis en el sector, para, a continuación, presentar los SIP realizados o iniciados hasta la fecha, haciendo especial referencia al sector del crédito cooperativo europeo, con un análisis econométrico centrado en España. Este análisis pretende determinar en qué medida los factores de mayor influencia en la constitución de un SIP están relacionados con la homogeneidad en el modelo de negocio. Del análisis realizado se ha podido demostrar que los criterios de homogeneidad en variables relacionadas con el modelo de negocio pesan más en las cooperativas de crédito que en las cajas de ahorros

    Full Text Available El análisis de eficiencia relativa hospitalaria resulta un tema trascendental para la Caja Costarricense de Seguro Social, dado que le permite determinar cuáles de los hospitales presentan un mejor desempeño relativo y cuáles podrían mejorar el uso de los recursos. El objetivo es analizar la eficiencia técnica hospitalaria en Costa Rica. Se utilizaron datos del 2012-2013 para los hospitales generales de la Caja Costarricense de Seguro Social. Para determinar la eficiencia hospitalaria se utiliza el análisis envolvente de datos con dos insumos: gasto en hospitalización y las camas y tres productos: actividad hospitalaria ajustada por casuística, índice de funcionamiento e índice de mortalidad intrahospitalaria ajustada por riesgo. Los resultados muestran que el nivel de eficiencia varía sustancialmente entre los 23 hospitales analizados. En 2013, un 30% de los hospitales resultó ser eficiente técnicamente, situación que mejoró levente respecto a 2012. Este trabajo es una primera aproximación del análisis de eficiencia de los hospitales públicos de Costa Rica. Se realizó un esfuerzo para homogenizar los datos, al ajustar las variables para considerar la complejidad y el riesgo de los casos que maneja cada hospital, de tal forma que los resultados sean comparables entre centros de diferentes tamaño y complejidad. Como conclusión se tiene que el 70% de los hospitales puede mejorar el uso de los recursos.

  15. Pilot experiment to control Medfly, Ceratitis capitata (Wied.) (Diptera: Tephritidae) using mass trapping technique in a custard apple (Annona cherimolia Mill.) orchard

    Recently, as a result of assays coordinated by the International Atomic Energy Agency (and participated by Spain), it was decided that ammonium acetate, putrescine and trimethylamine be included in low release polyetilene bag dispensers (Biolure, Consep, Co) as the Mediterranean fruit fly (Medfly) females were greatly attracted by them. These synthetic substances are placed in traps at the frequency of one and a half months to two months. If Tephry traps are used, one DDVP wafer (containing Vapona or a similar substance) is enough to kill the flies that enter them. These attractants make it unnecessary to replenish the liquids in the Mcphail traps and remain effective throughout the entire fruit season. The Caja Rural de Granada (a bank of farmers) encourages all techniques that increase crop profits for farmers. It is even more desirable if such crop profitability can be achieved without the application of insecticides which may result in the likely presence of toxic residues. In the light of the results achieved by the attractants with regard to female Medflies, the Caja Rural de Granada, together with the National Institute of Agricultural Research Counselling (Agricultural Department), performed an experiment on mass trapping to confirm whether it is possible to protect a fruit plantation with the application of this biotechnical method. Due to the great risk of this initial experiment, the farmers were free to use insecticides as often as they deemed necessary so that no damages due to any plague could be blamed on the experiment

    The unique properties of nylon membranes allow for dramatic improvement in the capillary transfer of DNA restriction fragments from agarose gels (Southern blotting). By using 0.4 M NaOH as the transfer solvent following a short pre-treatment of the gel in acid, DNA is depurinated during transfer. Fragments of all sizes are eluted and retained quantitatively by the membrane; furthermore, the alkaline solvent induces covalent fixation of DNA to the membrane. The saving in time and materials aff...
