    The impact of coal mine dump contaminated soil on the elemental uptake by two edible plants, namely, Amaranthus dubius (red herbs) and Amaranthus hybridus (green herbs), was studied by investigating their response and ability to tolerate and accumulate varying levels of elements in their roots and shoots. The vegetation was grown on varying amounts of contaminated soil, viz. 0%, 5%, 15%, 25% w/w using coal mine dump soil. The soil was analyzed for soil pH, cation exchange capacity (CEC), soil organic matter (SOM), moisture content, and selected heavy metals. The distribution of six metals, namely, Pb, Cd, Hg, Ni, Mn, and Fe, in roots, stem, and leaves of the plants was determined in two stages of growth after 5 weeks and 10 weeks. All soil and plant samples were microwave digested and subjected to heavy metal analysis using the ICP-OES, GFAAS, and CVAAS. The pH of the coal mine dump contaminated soil decreased with an increase in contamination. Both the SOM and CEC values decreased, which increases the availability of elements, by providing more binding sites in the soil. Relatively, the red herbs had higher elemental concentrations than the green herbs. Both plants recorded high manganese accumulation. No mercury was detected in the soils or plants.

Theaim of the present study was to investigate the nutraceutical potentialities of four Amaranthus species from Burkina Faso. The aqueous decoction extract of the four species contains the highest ofpolyphenols, flavonoids,flavonols and proteins contents. The aqueous decoction extracts were used for the evaluation of the antioxidant activity and xanthine oxidase inhibitory potentiality. The A. dubius showed the most potent antioxidant activity with a CE50 of 1.26±0.46, mgm2 the β-carotene bleaching method. A. hybridus showed the most potent antioxidant activity (66.99±1.65 μmolAEAC/g in the DPPH radical scavengingmethod. The aqueous extracts of the four speciesshowed weak inhibition of the xanthine oxidaseat the concentration of 200 μg/mL.The four Amaranthus species are rich in microelements (Na, K, Ca, Mg, P, Fe, Mn, Zn and Cu and carotenoids compounds. The antinutritionals factors were also quantified. The oxalate amount in these species is fairly high. The highest minerals contents and the antioxidant activity of the amaranths could explain theirlarge use by all the socioeconomic strata of the population.These plants would constitute a source of dietetic antioxidants.

  11. The effect of gamma irradiation on Nematospiroides dubius

    International Nuclear Information System (INIS)

    Mice were infected with gamma irradiated larvae of Nematospiroides dubius and autopsied 5 weeks later for worm counts. It was found that male worms were more susceptible to irradiation than female worms. In both instances, however the survival curve on a semi logarithmic plot was characterised by a shoulder at low doses and an exponential component at the higher levels of exposure. No male worms were recovered from mice infected with larvae given more than 12 krad but some female worms were capable of surviving 20 krad. The fecundity of female worms was reduced by 61% at 4 krad and totally ablated at 8 krad. Further experiments demonstrated that the survival of irradiated N. dubius in vivo was related to the extent of the damage caused at the time of irradiation and was not dependent on additional host parameters. Thus neither the number of irradiated worms inoculated nor the sex of the host radically altered the sex ratio or proportion of the worms lost as a result of irradiating the larvae. Furthermore, treatment with cortisone or sublethal irradiation of the host did not increase the proportion of surviving worms. It was therefore, concluded that a host immune response was not involved. (author)

    Bites by tarantulas (Theraphosidae, Mygalomorphae) in humans can result in mild clinical manifestations such as local pain, erythema, and edema. Vitalius dubius is a medium-sized, nonaggressive theraphosid found in southeastern Brazil. In this work, we investigated the mediators involved in the plasma extravasation caused by V. dubius venom in rats. The venom caused dose-dependent (0.1-100 μg/site) edema in rat dorsal skin. This edema was significantly inhibited by ((S)1-{2-[3(3-4-dichlorophenyl)-1-(3-iso-propoxyphenylacetyl)piperidine-3-yl]ethyl}-4-phenyl-1-azoniabicyclo[2.2.2]octone, chloride) (SR140333, a neurokinin NK1 receptor antagonist), indomethacin [a nonselective cyclooxygenase (COX) inhibitor], cyproheptadine (a serotonin 5-hydroxytryptamine1/2 and histamine H1 receptor antagonist), and N(ω)-nitro-L-arginine methyl ester (a nitric oxide synthase inhibitor). In contrast, mepyramine (a histamine H1 receptor antagonist), D-Arg-[Hyp(3),Thi(5),D-Tic(7),Oic(8)-]-BK (JE 049, a bradykinin B2 receptor antagonist), and ((S)-N-methyl-N-[4-(4-acetylamino-4-phenylpiperidino)-2-(3,4-di-chlorophenyl)butyl]benzamide) (SR48968, a neurokinin NK2 receptor antagonist) had no effect on the venom-induced increase in vascular permeability. In rat hind paws, the venom-induced edema was attenuated by ketoprofen (a nonselective COX inhibitor) administered 15 minutes postvenom. Preincubation of venom with commercial antiarachnid antivenom attenuated the venom-induced edema. These results suggest that the enhanced vascular permeability evoked by V. dubius venom involves serotonin, COX products, neurokinin NK1 receptors, and nitric oxide formation. The attenuation of hind paw edema by ketoprofen suggests that COX inhibitors could be useful in treating the local inflammatory response to bites by these spiders. PMID:26607257

    10 April 2004 Marte Valles is an outflow channel system that straddles 180oW longitude between the region south of Cerberus and far northwestern Amazonis. The floor of the Marte valleys have enigmatic platy flow features that some argue are formed by lava, others suggest they are remnants of mud flows. This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows an island created in the middle of the main Marte Valles channel as fluid---whether lava or mud---flowed past two older meteor impact craters. The craters are located near 21.5oN, 175.3oW. The image covers an area about 3 km (1.9 mi) across. Sunlight illuminates the scene from the lower left.

    This site is located at 16 deg N, 177 deg W on the flood plains of Marte Valles, which is perhaps the youngest channel system on Mars. The young age of this channel warrants investigation because of climatic implications for fluvial activities in recent geologic time. The paucity of craters makes this an excellent site in terms of safety requirements. Some of the objectives stated previously for the Maja Valles region would also apply to this site (grab bag of rock types, etc.).

    MGS MOC Release No. MOC2-442, 4 August 2003The Marte Vallis system, located east of Cerberus and west of Amazonis Planitia, is known for its array of broken, platy flow features. This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows a close-up view of some of these plates; they appear to be like puzzle pieces that have been broken apart and moved away from each other. The Mars science community has been discussing these features for the past several years--either the flows in Marte Vallis are lava flows, or mud flows. In either case, the material was very fluid and had a thin crust on its surface. As the material continued to flow through the valley system, the crust broke up into smaller plates that were then rafted some distance down the valley. This picture is located near 6.9oN, 182.8oW. It is illuminated by sunlight from the left.

    20 March 2006 This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows platy flow surfaces in the Marte Vallis region of Mars. The origin of the flows is not well-understood, but as some Mars scientists have suggested, the flows may be the product of low viscosity (very fluid), high temperature volcanic eruptions, or perhaps they are the remains of large-scale mud flows. In either case, the materials are solid and hold a record of small meteor impact craters, thus indicating that they are not composed of ice, as still others have speculated.

  16. Uptake of 134Cs in the shoots of Amaranthus tricolor and Amaranthus cruentus

    International Nuclear Information System (INIS)

    Amaranthus tricolor and Amaranthus cruentus responded differently to 134Cs and addition of (NH4)2SO4. - Amaranthus tricolor L. and Amaranthus cruentus L. were grown in pots containing 7.5 kg soils artificially contaminated with three levels of 134Cs activity: 5.55x105 Bq pot-1, 1.11x106 Bq pot-1, and 1.665x106 Bq pot-1, respectively. Forty-nine days after sowing and growth, plants were harvested. The plants growing in soils with increasing 134Cs concentrations showed increasing concentration of this radionuclide in shoots. There were significant differences in uptake of 134Cs applied to soils between and within the plant species, depending on the initial 134Cs concentrations. The plant species showed different responses to the addition of (NH4)2SO4 to soils. Biomass production of both species was reduced in pots treated with (NH4)2SO4. (NH4)2SO4 application decreased the uptake of 134Cs by A. tricolor but increased the accumulation of 134Cs by A. cruentus, showing that chemicals with the highest efficiency to enhance the desorption of 134Cs might play an unexpected role in transferring the radionuclide to shoots

    Amaranthus tricolor and Amaranthus cruentus responded differently to {sup 134}Cs and addition of (NH{sub 4}){sub 2}SO{sub 4}. - Amaranthus tricolor L. and Amaranthus cruentus L. were grown in pots containing 7.5 kg soils artificially contaminated with three levels of {sup 134}Cs activity: 5.55x10{sup 5} Bq pot{sup -1}, 1.11x10{sup 6} Bq pot{sup -1}, and 1.665x10{sup 6} Bq pot{sup -1}, respectively. Forty-nine days after sowing and growth, plants were harvested. The plants growing in soils with increasing {sup 134}Cs concentrations showed increasing concentration of this radionuclide in shoots. There were significant differences in uptake of {sup 134}Cs applied to soils between and within the plant species, depending on the initial {sup 134}Cs concentrations. The plant species showed different responses to the addition of (NH{sub 4}){sub 2}SO{sub 4} to soils. Biomass production of both species was reduced in pots treated with (NH{sub 4}){sub 2}SO{sub 4}. (NH{sub 4}){sub 2}SO{sub 4} application decreased the uptake of {sup 134}Cs by A. tricolor but increased the accumulation of {sup 134}Cs by A. cruentus, showing that chemicals with the highest efficiency to enhance the desorption of {sup 134}Cs might play an unexpected role in transferring the radionuclide to shoots.

    Full Text Available Selection of genotypes with adequate combination of traits with high yield at the appropriate density level increased the productivity in amaranth. The study was therefore undertaken to estimate genetic attributes of different amaranth genotypes and to identify and select genotypes with adequate trait combination for improvement in yield. In grain amaranthus (Amaranthus hypochondriacus L. ten genotypes were evaluated  for twelve characters under four plant density levels viz., very high (D1, high (D2, normal (D3 and low plant density (D4 to study the different selection parameters for grain yield and its eleven contributing morphological and quality traits. The study was conducted at College Orchard, Department of Horticulture, Pandit Jawaharlal Nehru College of Agriculture and Research Institute, TNAU, Karaikal during rabi 2007. The results revealed that the GCV was maximum in high plant density when compared to very high, normal and low plant density levels for the characters viz., fresh weight of the inflorescence, length of the rachis per inflorescence, grain yield per plant and total carbohydrates. Leaf area at 50 per cent flowering, fresh weight of the inflorescence, number of secondary branches per inflorescence and total carbohydrates are recorded high magnitude of genetic variability in combination with high heritability and genetic advance as per cent of mean in all the four plant density levels.

  13. Role of ethylene metabolism in Amaranthus retroflexus

    International Nuclear Information System (INIS)

    14C-Ethylene was metabolized by etiolated pigweed seedlings (Amaranthus retroflexus L.) in the manner similar to that observed in other plants. The hormone was oxidized to 14CO2 and incorporated into 14-tissue components. Selected cyclic olefins with differing abilities to block ethylene action were used to determine if ethylene metabolism in pigweed is necessary for ethylene action. 2,5-Norbornadiene and 1,3-cyclohexadiene were effective inhibitors of ethylene action at 800 and 6400 μ1/1, respectively, in the gas phase, while 1,4-cyclohexadiene and cyclohexene were not. However, all four cyclic olefins inhibited the incorporation and conversion of 14C-ethylene to 14CO2 by 95% with I50 values below 100 μ1/1. The results indicate that total ethylene metabolism does not directly correlate with changes in ethylene action. Additionally, the fact that inhibition of ethylene metabolism by the cyclic olefins did not result in a corresponding increase in ethylene evolution, indicates that ethylene metabolism does not serve to significantly reduce endogenous ethylene levels

  10. Neuroprotective effect of Amaranthus lividus and Amaranthus tricolor and their effects on gene expression of RAGE during oxidative stress in SH-SY5Y cells.

    Science.gov (United States)

    Amornrit, W; Santiyanont, R

    2016-01-01

    Amaranthus plants, or spinach, are used as food sources worldwide. Amaranthus leaves are rich in antioxidant compounds, which act as free radical scavengers. Oxidative stress caused by the aberrant production of reactive oxygen species (ROS) represents an important mechanism for neuronal dysfunction and cell loss in different neurodegenerative disorders. The neuroprotective effects of antioxidant-containing plants have been extensively demonstrated in different models of neurotoxicity. However, few studies have investigated the antioxidant properties of Amaranthus extracts and their effect on the nervous system. In the present study, the leaves of Amaranthus lividus and Amaranthus tricolor were extracted using petroleum ether, dichloromethane, and methanol. Results indicated that antioxidant activities were the highest in methanol extracts from both kinds of Amaranthus leaves. In addition, oxidative stress was induced in human neuroblastoma cell lines (SH-SY5Y) by using H2O2. Intracellular oxidative stress, cytotoxicity, and gene expression of RAGE were then determined. In vitro results demonstrated that pretreatment with A. lividus and A. tricolor extracts can significantly decrease cell toxicity and intracellular ROS production in SH-SY5Y cells. Interestingly, the extracts also significantly downregulated the expression of oxidative stress genes such as HMOX-1, RAGE, and RelA/ NF-κB. Our results suggested that Amaranthus leaves may be useful for reducing oxidative stress and may be beneficial for age-related diseases and neurodegenerative disorders. PMID:27173239

  11. Will the Amaranthus tuberculatus Resistance Mechanism to PPO-Inhibiting Herbicides Evolve in Other Amaranthus Species?

    Directory of Open Access Journals (Sweden)

    Chance W. Riggins

    2012-01-01

    Full Text Available Resistance to herbicides that inhibit protoporphyrinogen oxidase (PPO has been slow to evolve and, to date, is confirmed for only four weed species. Two of these species are members of the genus Amaranthus L. Previous research has demonstrated that PPO-inhibitor resistance in A. tuberculatus (Moq. Sauer, the first weed to have evolved this type of resistance, involves a unique codon deletion in the PPX2 gene. Our hypothesis is that A. tuberculatus may have been predisposed to evolving this resistance mechanism due to the presence of a repetitive motif at the mutation site and that lack of this motif in other amaranth species is why PPO-inhibitor resistance has not become more common despite strong herbicide selection pressure. Here we investigate inter- and intraspecific variability of the PPX2 gene—specifically exon 9, which includes the mutation site—in ten amaranth species via sequencing and a PCR-RFLP assay. Few polymorphisms were observed in this region of the gene, and intraspecific variation was observed only in A. quitensis. However, sequencing revealed two distinct repeat patterns encompassing the mutation site. Most notably, A. palmeri S. Watson possesses the same repetitive motif found in A. tuberculatus. We thus predict that A. palmeri will evolve resistance to PPO inhibitors via the same PPX2 codon deletion that evolved in A. tuberculatus.

    The aim of the study was to confirm the presence of rutin, one of the most common quercetin glycosides, and other quercetin derivatives in plants of genus Amaranthus, to investigate the influence of the species and variety on rutin distribution in the plant and content changes during growing season. The rutin content was determined by micellar electrokinetic capillary chromatography in individual plant parts at the beginning of the growth, at the flowering stage and at the maturity stage of five Amaranthus species. The total quercetin content was determined by micellar electrokinetic capillary chromatography too. The rutin content in amaranth ranged from 0.08 (in seeds) to 24.5 g/kg dry matter (in leaves). Comparison of the determined total quercetin content and the calculated content of quercetin released from rutin did not prove important presence of quercetin or other quercetin derivatives than rutin. Only amaranth leaves sampled at the maturity stage probably contained quercetin or quercetin derivatives. Significant differences in the rutin content were established among species and as well varieties. Amaranthus hybrid and A. cruentus were the best sources of rutin. PMID:19067170

    This essay explores the relationship between commerce and culture in the context of the recent debate over the social effect of Wal-Mart. In spite of much public debate, little is known about how Wal-Mart affects values. Using data collected from multiple sources, we show there is little evidence that Wal-Mart makes communities more conservative or more progressive.

  4. Assessing nitrogen supply potential and influence on growth of lettuce and amaranthus of different aged composts

    International Nuclear Information System (INIS)

    This study assessed the potential of different composts at different maturity stages to supply N and their effect on the vegetative growth of lettuce and Amaranthus. Five composts aged 1, 3, 6, 9, and 12 months, were mixed with soil at the rate of 5%, 10% and 15% then seeded with lettuce and Amaranthus. Results showed that 1, 3 and 6 month aged composts had a negative effect on plant height of lettuce and Amaranthus as 1-15.78% and 4.78 to 29.45% decrease in plant height over control was recorded respectively. On the other hand 9 and 12 month aged composts had a significant positive effect on plant height of lettuce and Amaranthus where 43.48% and 34.8% increase over control was recorded with the application of 15% of 12 month aged compost respectively. A similar effect was observed on fresh biomass of both lettuce and Amaranthus where a 386% and 59.43% increase over control was recorded with the application of 15% of 12 month aged compost respectively. One and three month aged composts revealed a negative effect on N absorption by lettuce whereas 1, 3, 6 and 9 month aged composts had a negative effect on N absorption by Amaranthus. 30.39% and 21.48% increases over control in N absorption by lettuce and Amaranthus respectively were recorded with the application of 15% of 12 month aged compost.

  12. Genotypic Variations in Potassium Absorption and Utilization by Amaranthus spp.

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    The kinetics of K+ absorption and the utilization of both applied K and K in a calcareous alluvisol with low available K by different genotypes of grain amaranth (Amaranthus spp.), an ancient pseudo-cereal that produces a large biomass and a rich source of healthy nutrients and mineral elements, were studied by means of ion depletion technique and pot experiments. Grain amaranth had a high affinity for K+ uptake in comparison with corn and cotton. However, there were differences among Amaranthus spp. in K absorption and utilization. Some cultivars such as R104, CX-4, Du001, Hy015 and Hr029 which had a higher rate of K absorption and stronger affinity for K+ were typical varieties with high K-use efficiency (KUE). The results showed that high KUE cultivars grew quickly, possessed stronger ability to take up soil slowly available K and mineral K, and did not respond to K fertilization in the soil with low available K. Correspondingly, grain amaranth cultivars CX-77, Cr024, Vd001, Re003 and Sn003 were relatively low in KUE. Compared with high KUE cultivars, they took up more soil available K and both of their dry matter accumulation and K uptake responded to K applied significantly.

    2014-09-01

    Full Text Available Genotype specific fingerprints were detected in two grain amaranthus varieties KBGA1 and Suvarna using SSR and RAPD markers. In this study 41 Pigeon Pea SSR markers and 6 RAPD markers were used to generate DNA fingerprints for the two varieties of grain amaranthus. Analysis of polymorphic fragments generated from SSR and RAPD markers revealed the genetic variation between grain amaranthus varieties KBGA1 and Suvarna. The results indicate that DNA markers are appropriate tools for assessing genetic variation within and between the species of amaranthus and suggest that cultivated varieties of Amaranthus have significant genetic variation. The differences generated by the markers can be used as fingerprints for detecting the varieties. This is the first report of the utilization of legume microsatellite markers in Amaranthus.

Os três ensaios, conduzidos separadamente, utilizaram cinco densidades de sementes por vaso. Em termos gerais, as sementes germinadas prontamente foram a razão do surgimento da próxima geração, visto que estabeleceram plântulas rapidamente e estas venceram em competição. A partir de certo número de sementes semeadas (20 por vaso, o número de plantas adultas obtidas revelou-se independente do número de sementes semeadas, o que indica que a capacidade de suporte do ambiente, ao invés do tamanho do banco de sementes no solo, é a razão da regulação do tamanho populacional; a mesma observação aplica-se à produção de matéria seca. Sob condições de competição, as espécies A. hybridus - tipo verde e A. viridis produziram maior quantidade de biomassa para reprodução (22% a 34% do que A. hybridus - tipo roxo (15% a 18%. As primeiras, portanto, revelaram-se mais estrategistas-r que a última.Intraspecific competition trials were carried out for Amaranthus viridis L. and A. hybridus L., the latter species with two distinct biotypes, a green and a purple type. Three independent trials were made, with five different seed densities per pot for each species or biotype. In general terms, seeds that germinated promptly were responsible for the formation of the next generation, these early seedlings being more competitive. The carrying capacity was reached with 20 seeds per pot, no increase in the number of adult plants observed by increasing the seed density. This shows that the environmental suporting capacity, not the size of the seed bank in the soil, regulates the population size. A similar conclusion holds true for dry matter yield. Under competition, the species A. hybridus - green biotype and A. viridis produced larger biomass for reproductive

    Wal-Mart® has created tremendous economic benefits for consumers by providing more choices at lower prices. The benefits are felt especially in communities that had only local retail monopolies prior to the arrival of the store. Yet no mretailer evokes stronger negative emotions than this chain. Recent media attention has focused on questionable labor practices and low wages combined with lack of benefits paid by the corporation, while academic studies have examined effects of the stores on r...

  17. Development and evaluation of mutant germplasm of Amaranthus

    International Nuclear Information System (INIS)

    Seeds of Amaranthus tricolor were gamma irradiated and M1 seedlings planted in the field or in wooden boxes in greenhouses to screen for early drought tolerance. Drought tolerance was confirmed in similar subsequent screening steps, and seeds were collected from selected drought tolerant M2, M3, M4 and M5 plants. The mutation induction and selection procedure, constraints and characteristics of the mutated plants are described, with emphasis on selection for early drought tolerance. A. tricolor putative mutants showed strong drought avoidance and drought tolerance characteristics during severe moisture stress, and recovery after rewatering was within a few hours, with re-growth within a few days. This study is part of a project to develop tolerant genotypes of neglected vegetable crops that could contribute to food production in rural areas in Africa and the rest of the world. (author)

    This paper describes a preliminary assessment of the nutraceutical value of Amaranthus cruentus (A. cruentus) and Amaranthus hybridus (A. hybridus), two food plant species found in Burkina Faso. Hydroacetonic (HAE), methanolic (ME), and aqueous extracts (AE) from the aerial parts were screened for in vitro antioxidant and xanthine oxidase inhibitory activities. Phytochemical analyses revealed the presence of polyphenols, tannins, flavonoids, steroids, terpenoids, saponins and betalains. Hydroacetonic extracts have shown the most diversity for secondary metabolites. The TLC analyses of flavonoids from HAE extracts showed the presence of rutin and other unidentified compounds. The phenolic compound contents of the HAE, ME and AE extracts were determined using the Folin-Ciocalteu method and ranged from 7.55 to 10.18 mg Gallic acid equivalent GAE/100 mg. Tannins, flavonoids, and flavonols ranged from 2.83 to 10.17 mg tannic acid equivalent (TAE)/100 mg, 0.37 to 7.06 mg quercetin equivalent (QE) /100 mg, and 0.09 to 1.31 mg QE/100 mg, respectively. The betacyanin contents were 40.42 and 6.35 mg Amaranthin Equivalent/100 g aerial parts (dry weight) in A. cruentus and A. hybridus, respectively. Free-radical scavenging activity expressed as IC50 (DPPH method) and iron reducing power (FRAP method) ranged from 56 to 423 µg/mL and from 2.26 to 2.56 mmol AAE/g, respectively. Xanthine oxidase inhibitory activities of extracts of A. cruentus and A. hybridus were 3.18% and 38.22%, respectively. The A. hybridus extract showed the best antioxidant and xanthine oxidase inhibition activities. The results indicated that the phytochemical contents of the two species justify their traditional uses as nutraceutical food plants. PMID:24281664

    Amaranthus cruentus (Amaranthaceae) is one of the popularly grown leafy vegetables in the Indian subcontinent. Leaves of the plant are rich in polyphenols, tannins, flavonoids, steroids, terpenoids, saponins, and betalains. The plant also contains rich amounts of protein, calcium, iron, vitamins A, E, and C, and folic acid. The present work was undertaken to evaluate the antianemic effect of Amaranthus cruentus. Ethanol extract of Amaranthus cruentus was prepared. Acute oral toxicity of the extract was determined by Organization for Economic Cooperation and Development (OECD) Guideline 423. Doses of 200 and 400 mg/kg were used in the present study. Phenylhydrazine (60 mg/kg, intraperitoneal injection for three consecutive days) was used to induce anemia in rats. After anemia induction, animals were treated with standard preparation and extract. Amaranthus cruentus extract significantly aided in restoring the levels of red blood cells, white blood cells (WBCs), and hemoglobin. There was also an increase in hematocrit. Thus, it can be concluded that Amaranthus cruentus is a rich source of phytochemicals that are responsible for demonstrating hematopoietic effects. Isolation and structure elucidation of constituents, responsible for antianemic activity, is necessary to affirm the aforementioned effect. PMID:27027824

    Cinnamoylphenethylamines are phenolic amides in which cinnamic acid provides the acid moiety and phenethylamine the amine moiety. Single ion monitoring (SIM) in LC-MS was performed on amaranth leaf extracts. Masses corresponding to sets of regioisomers, including previously reported compounds, were examined. Six peaks were detected and their corresponding standards synthesized for a quantitative LC-MS/MS investigation of cinnamoylphenethylamines in amaranth. Four cinnamoylphenethylamines (caffeoyltyramine, feruloyldopamine, sinapoyltyramine, and p-coumaroyltyramine) are reported in the Amaranthaceae for the first time; also, one rare compound, feruloyl-4-O-methyldopamine, appeared to be quite common in the genus Amaranthus. Feruloyldopamine showed moderate antifungal activity toward an isolate of Fusarium culmorum. Our LC-MS approach, in conjunction with the straightforward synthesis, provides a simple, reliable way of quantitatively investigating cinnamoylphenethylamines in plants. Concentrations of cinnamoylphenethylamines vary widely: feruloyltyramine was present in quantities of 5.26 to 114.31 microg/g and feruloyldopamine in quantities of 0.16 to 10.27 microg/g, depending on the plant sample.

    Cardiovascular disease (CVD) is a major cause of disability and premature death throughout the world. Diets with antithrombotic components offer a convenient and effective way of preventing and reducing CVD incidence. The aim of the present work was to assess in vivo and ex vivo effects of Amaranthus hypochondriacus proteins on platelet plug formation and coagulation cascade. Amaranth proteins were orally administrated to rats (AG, 8 animals) and bleeding time was determined showing no significant difference compared with control rats (CG, 7 animals). However, results show a strong tendency, suggesting that amaranth proteins are involved in the inhibition of thrombus formation. Non-anticoagulated blood extracted from animals was analyzed with the hemostatometer, where AG parameters obtained were twice the values showed by CG. The clotting tests, thrombin time (TT) and activated partial thromboplastin time (APTT), presented a 17 and 14% clotting formation increase respectively when comparing AG with CG. The ex-vivo assays confirm the hypothesis inferring that amaranth proteins are a potential antithrombotic agent. PMID:26627100

  9. Tolerance and accumulation characteristics of cadmium in Amaranthus hybridus L

    International Nuclear Information System (INIS)

    Because of its toxicity to animals and humans, cadmium (Cd) is an environmentally important heavy metal. Consequently, researchers are interested in using hyperaccumulator and accumulator plants to decontaminate Cd polluted soils. To investigate Cd tolerance, uptake and accumulation by Amaranthus hybridus L., Cd concentration gradients were applied to a soil (at rates of 0, 30, 60, 90, 120, 150 and 180 mg kg-1) and hydroponics solutions (at rates of 0, 5, 10, 15, 20, 30, and 40 mg L-1) following a field survey. A. hybridus grew normally at added Cd concentrations ≤ 90 mg kg-1 and ≤ 20 mg L-1 in the soil culture and in the hydroponics solutions, respectively. In the hydroponics solutions, peroxidase activity showed a quadratic relationship and catalase activity changed irregularly with increasing Cd concentrations. The highest Cd concentration and accumulation in shoots were 241.56 mg kg-1 and 1006.95 μg pot-1 in the soil culture, and 354.56 mg kg-1 and 668.42 μg pot-1 in the hydroponics experiment. Bioconcentration factors in soil culture and hydroponics solutions were 0.58-1.22 and 5.18-17.55, and translocation factors were 0.64-1.50 and 0.33-0.92, respectively. A. hybridus has potential phytoremediation capability in Cd polluted soils.

    The potential harm of soil cadmium pollution to ecological environment and human health has been increasingly widely concerned. Phytoremediation, as a kind of new and effective technology, has become an important method for cleaning up cadmium in contaminated sites. The amaranth (Amaranthus mangostanus L.) is widely distributed and has abundant varieties in China, its rapid growth and large biomass can be served as candidate for cadmium hyperaccumulators for phytoremediation. To obtain cadmium hyper-accumulator, Cd uptake in 23 amaranth euitivars from different ecological region was investigated under hydroponic culture condition. Meanwhile, pot experiment was established to probe phytoremediation potentiality of Cd contaminated soil by amaranth. Three treatment (Cd 5, 10, and 25 mg kg-1) were imposed to red soil, yellow brown soil, and vegetable soil. The results showed that under hydroponic culture with Cd 3 mg L-1, the cadmium concentration in the shoots of the cultivar Tianxingmi reached 260 mg kg-1, and its total cadmium uptake was the highest among various cultivars. In the treatment Cd 25 mg kg-1, the cadmium concentration in the shoots of the cultivar Tianxingmi reached 212 mg kg-1, while bioaccumulation factor and shoot purification rate reached 8.50 and 3.8%, respectively. Further, the total biomass and shoot biomass were not decreased significantly under Cd exposure.These results suggested that eultivar Tianxingmi is a typical Cd hyperaccumulator, and can be expected to be used in phytoremediation of Cd contaminated soil.

    Full Text Available Chenopodium quinoa Wild. and Amaranthus caudatus L., two plant species from South America, have small and numerous chromosomes. Looking for chromosome markers to distinguish pairs of homologous chromosomes double fluorescence staining, in situ hybridization with 45S rDNA and silver staining were applied. Fluorescent in situ hybridization with 45S rDNA has shown two sites of hybridization occurring on one pair of chromosomes in qunion genre (lines PQ-1, PQ-8. The number of RDA loci in Amaranth's caudate L. genre depends on the accession. Kiwicha 3 line has one pair of chromosomes with signals and Kiwicha Molinera cultivar two pairs. All observed rDNA loci were active. After chromomycin/DAPI staining in all cases, except Kiwicha Molinera cultivar, the CMA3 positive bands co-localized with signals of in situ hybridization with rDNA. In Kiwicha Molinera the number of CMA+ bands was higher than the number of 45S rDNA signals after FISH.

    Full Text Available Weeds compete with field crops mainly for water, light and nutrients, and this competition is among other factors, a function of the occurrence of weed density, and the intrinsic competitive ability of each vegetal species. The objective of this research was to evaluate the competitive ability of five weed species of the Amaranthus L. genus (A. deflexus, A. hybridus, A. retroflexus, A. spinosus and A. viridis with dry bean plants (Phaseolus vulgaris L. - 'Carioca Precoce' cultivar, using the replacement series design. A fixed total density equivalent to 80 plants m-2 was used in pots of 2.8 L capacity varying the proportions between the species in coexistence. To install the experiment, Amaranthus seedlings were transplanted to the pots at the phenological stage of completely expanded cotyledon leaves, while the crop was seeded. A factorial scheme (5 x 5 was used to carry out the experiment, consisting of five species of Amaranthus (pigweeds and five species proportions (beans:pigweeds: 4:0, 3:1, 2:2, 1:3 and 0:4. Randomized blocks with four replicates were installed and the experiment was repeated twice. Dry bean plants were more competitive than each one of the five Amaranthus species when the species proportion was equivalent. A. deflexus and A. viridis were the weed species which phenology were less affected by the competition with dry bean; the intraspecific competition was more damaging for dry bean plants, suggesting that the damages caused by the weeds are more related to high density of infestation than to the intrinsic competitive ability of the species.As plantas daninhas competem com as culturas por água, luz e nutrientes, sendo que esta competição é função da densidade de ocorrência das plantas daninhas, bem como da habilidade competitiva intrínseca de cada espécie.

    Populations in North India depend on a number of vegetable crops of which Amaranthus spp. is the most important since it is the only crop available in the hot summer months when no other foliage crop grows in the field. However, reports on mineral composition of leaves are rare with absolutely no information on the qualitative improvement of foliage yield with special reference to minerals. Studies on correlation among the minerals as well as with yield and leaf attributes are also lacking. Hence, we report the proximate mineral composition in 30 strains of A. tricolor along with some suggestions for qualitative improvement of the foliage yield with reference to minerals. Our study showed that vegetable amaranth is a rich source of minerals like calcium (1.7 +/- 0.04 g/100 g), iron (1233.8 +/- 50.02 mg/kg), and zinc (791.7 +/- 28.98 mg/kg). The heritability estimates were high for most of the traits, with potassium and calcium showing high values, while comparatively lower values were recorded for magnesium and nickel. Nickel was the only mineral that showed positive correlation with all the minerals, as well as with leaf size and foliage yield. Zinc showed strong positive relationship with iron (0.66**) and manganese (0.74**), and was the only mineral exhibiting significant positive association with foliage yield. This study would be of use in enhancement of selected minerals in different regions according to local preferences and nutrient deficiency prevalent among the populations. PMID:16736385

    We evaluated and quantified prenatal growth of fishers (Martes pennanti) using ultrasonography. Seven females gave birth to 21 kits. The first identifiable embryonic structures were seen 42 d prepartum; these appeared to be unimplanted blastocysts or gestational sacs, which subsequently implanted in the uterine horns. Maternal and fetal heart rates were monitored from first detection to birth. Maternal heart rates did not differ among sampling periods, while fetal hearts rates increased from first detection to birth. Head and body differentiation, visible limbs and skeletal ossification were visible by 30, 23 and 21 d prepartum, respectively. Mean diameter of gestational sacs and crown-rump lengths were linearly related to gestational age (P < 0.001). Biparietal and body diameters were also linearly related to gestational age (P < 0.001) and correctly predicted parturition dates within 1-2 d. ?? 2004 Elsevier Inc. All rights reserved.

    Objective: To provide scientific validation for the antipyretic activities of Amaranthus viridis (Linn.), Amaranthus caudatus (Linn.) and Amaranthus spinosus (Linn.). Methods: The antipyretic activity of methanol extracts of all three plants at doses of 200 and 400 mg/kg was investigated by yeast induced pyrexia in rats. Paracetamol (150 mg/kg, p.o.) was used as reference drug and control group received distilled water. Rectal temperatures of all the rats were recorded and compared at 19 h, immediately before extract or vehicle or paracetamol administration, and again at 1 h interval up to 24 h by thermal probe Eliab themistor thermometer. Results: At 400 mg/kg dose all the three methanolic extracts showed significant (P<0.01) reduction in yeast provoked elevated temperature as compared with that of standard drug paracetamol, whereas 200 mg/kg dose is less effective when compared with higher dose (P<0.05). Conclusions: The results show that methanol extract of three plants of Amaranthus possesses a significant antipyretic effect in maintaining reducing yeast-induced elevated body temperature in rats and their effects were comparable to that of the standard antipyretic drug paracetamol.

    Full Text Available La martora, Martes martes, è un mustelide storicamente presente su gran parte del territorio italiano, soprattutto dove siano presenti foreste mature altamente strutturate e ricche di risorse. Nel corso dei decenni passati, cause quali la deforestazione con conseguente frammentazione dell'habitat, la caccia e la persecuzione da parte dell'uomo hanno portato ad un sensibile declino sia nel numero d'individui sia di popolazioni in tutta l'Europa. Frammentazione degli areali e diminuzione del numero di soggetti costituiscono le cause principali di un limitato flusso genico con conseguente formazione di popolazioni isolate di martora e perdita di variabilità genetica (Kyle et al., 2003. Per queste ragioni la martora risulta attualmente tutelata secondo quanto previsto dalla Convenzione di Berna (appendice III e dalla Direttiva europea 92/43/CEE "Habitats & Species". Di fronte a prospettive di tipo conservazionistico, diventa necessario disporre di metodologie per la valutazione della variabilità residua nella specie a livello d'individui e di popolazioni. Secondo numerosi Autori, i microsatelliti costituiscono marcatori molto efficaci nella descrizione della struttura genetica e della storia demografica di specie (Beaumont & Bruford, 1999; Linares, 1999. Il presente lavoro propone i risultati ottenuti attraverso il confronto di due campioni costituiti da individui di Martes martes provenienti dalla Sardegna (25 esemplari e dal territorio italiano (6 esemplari. L'analisi è stata condotta a livello di 7 loci microsatellitari dinucleotidici polimorfici. Il valore di FST calcolato dal confronto dei due gruppi è risultato pari a 0,102 e ricade nel range di variazione identificato di recente in popolazioni nord-europee di martora (Kyle et al., 2003. L'analisi della varianza molecolare (AMOVA, condotta a due livelli gerarchici, ha permesso in particolare di ripartire la varianza del campione

  2. The coming electric Wal-Mart

    International Nuclear Information System (INIS)

    Market power in the competitive electric marketplace will depend on being a low-price leader. Electric utility executives are beginning to peer over the wall into the emerging world of competitive electric markets. Many will be terrified by the uncertainties and disorder associated with new service offerings such as retail wheeling and the transformation of other vestiges of the vertically integrated electric monopolies known for the past 100 years. The potential for increased competition for retail customers promises to have as fundamental an effect on the electric utility industry as Wal-Mart has had on retailing. Firms that are prepared for the new competitive environment will be in the strongest position to respond to the marketplace; those that are not prepared might want to consider the fate of the corner five-and-dime. To remain competitive, utility executives must take proactive steps to redefine their vision of their company's future. Such a redefinition must include a candid assessment of the strategies to be taken to reposition their firm to succeed, not just within the existing service area but in multiple markets

    Validation by means of simulation is a crucial step when developing real-time control systems. Modeling and simulation are an essential tool since the early design phase, when the control algorithms are designed and tested. This phase is commonly carried out in off-line environments such as Matlab and Simulink. A MARTe-based simulator has been recently developed to validate the new JET Vertical Stabilization (VS) system. MARTe is the multi-thread framework used at JET to deploy hard real-time control systems. This paper presents the software architecture of the MARTe-based simulator and it shows how this tool has been effectively used to evaluate the effects of Edge Localized Modes (ELMs) on the VS system. By using the simulator it is possible to analyze different plasma configurations, extrapolating the limit of the new vertical amplifier in terms of the energy of the largest rejectable ELM.

    We report on the design, operation, and data analysis methods employed on the VNIR imaging spectrometer instrument that was part of the Mars Astrobiology Research and Technology Experiment (MARTE). The imaging spectrometer is a hyperspectral scanning pushbroom device sensitive to VNIR wavelengths from 400-1000 nm. During the MARTE project, the spectrometer was deployed to the Río Tinto region of Spain. We analyzed subsets of three cores from Río Tinto using a new band modeling technique. We found most of the MARTE drill cores to contain predominantly goethite, though spatially coherent areas of hematite were identified in Core 23. We also distinguished non Fe-bearing minerals that were subsequently analyzed by X-ray diffraction (XRD) and found to be primarily muscovite. We present drill core maps that include spectra of goethite, hematite, and non Fe-bearing minerals.

    International Nuclear Information System (INIS)

    India has a rich heritage of medicinal plants, many of which have been explored for the various bioactivities since ages, but the radioprotective potential of the plants have been hardly explored. Since Amaranthus, a common weed and very often caten as vegetable by rural population, has been used as emollient, astringent, diuretic, blood purifier, hemorrhagic diathesis and biliousness from time immemorial. Hence the present study aims to judge whether Amaranthus paniculatus (Linn) has the antiradiation efficacy against radiation induced histopathological and biochemical alterations in mice liver. Amaranthus paniculatus (Linn) belongs to family Amaranthaceae and commonly called as Amaranth, has good natural sources of carotenoids (beta carotene-1490 μg/100 gm of edible portion), vitamin C and high level of critical lysine and methionine, protein content (22 gm/100 gm of edible portion). Swiss albino mice of 6-8 weeks weighing 22 ± 3 gm were selected from an inbred colony and divided into four groups. One group served as normal and two groups were administered with alcoholic extract at a dose of 600 mg/Kg-body weight/day dissolved in distilled water for fifteen days. Fourth group was given distilled water, orally and ad libitum. Then two groups, one with drug treated and another with distilled water treated, were exposed to 5 Gy of gamma radiation at the dose rate of 1.07 Gy/min with a source to surface distance (SSD) of 77.5 cm. The animals were autopsied at 1, 3, 7, 15 and 30 days post exposure. the optimum dose was calculated to be 600mg/kg b.wt/day after treating mice with AE for fifteen consecutive days prior to irradiation (9 Gy) to get maximum protection against radiation injury. By the survival assay, DRF 1.43 was calculated with different doses of gammas radiation (6, 9, 12 Gy). The radiation induced augmentation in MDA, protein, glycogen, alkaline and acid phosphatase content of liver is significantly ameliorated by the drug. The radiation induced

  13. BioMart – biological queries made easy

    Directory of Open Access Journals (Sweden)

    Thorisson Gudmundur

    2009-01-01

    Full Text Available Abstract Background Biologists need to perform complex queries, often across a variety of databases. Typically, each data resource provides an advanced query interface, each of which must be learnt by the biologist before they can begin to query them. Frequently, more than one data source is required and for high-throughput analysis, cutting and pasting results between websites is certainly very time consuming. Therefore, many groups rely on local bioinformatics support to process queries by accessing the resource's programmatic interfaces if they exist. This is not an efficient solution in terms of cost and time. Instead, it would be better if the biologist only had to learn one generic interface. BioMart provides such a solution. Results BioMart enables scientists to perform advanced querying of biological data sources through a single web interface. The power of the system comes from integrated querying of data sources regardless of their geographical locations. Once these queries have been defined, they may be automated with its "scripting at the click of a button" functionality. BioMart's capabilities are extended by integration with several widely used software packages such as BioConductor, DAS, Galaxy, Cytoscape, Taverna. In this paper, we describe all aspects of BioMart from a user's perspective and demonstrate how it can be used to solve real biological use cases such as SNP selection for candidate gene screening or annotation of microarray results. Conclusion BioMart is an easy to use, generic and scalable system and therefore, has become an integral part of large data resources including Ensembl, UniProt, HapMap, Wormbase, Gramene, Dictybase, PRIDE, MSD and Reactome.

    Luiz Alfredo Rodrigues Pereira

    2000-01-01

    Full Text Available Pneumatophores of Mauritia vinifera Mart. were collected from six month-old plants maintained submerged in fresh water to induce pneumatophore formation. Twenty day-old pneumatophores had a quite prominent root cap. The epidermis was composed of hexagonal cells, tangentially distributed along the cylindric surface of the organ. In transverse section these pneumatophores had a simple epidermis over several layers of sclerified parenchyma, which covered an aerenchyma with large intercellular spaces. The endodermal cells had Casparian strips. The vascular cylinder was polyarch, with a pith and surrounded by a unisseriate pericycle. Anatomically the 4 month-old pneumatophores were similar to the younger ones, except for the absence of the epidermis. The epidermis is replaced by a protective tissue, whose lignified and suberized cells projected themselves outwards, giving it a filamentous aspect. There was no accumulation of starch or tannins in the pneumatophores, except for the presence of statoliths in the root cap. No lenticels were observed in pneumatophores of M. vinifera. The main function of the pneumatophores of M. vinifera is to allow gas exchange, facilitating the supply of oxygen to the submerged root portions.Pneumatóforos de Mauritia vinifera Mart. foram coletados de plantas com seis meses de idade mantidas submersas em água com o objetivo de induzir a formação de pneumatóforos.

  18. Improvement of selected Amaranthus cultivars by means of mutation techniques and biotechnological approaches

    International Nuclear Information System (INIS)

    Pseudocereals like amaranth (Amaranthus ssp.), with high numbers of species exhibiting a high degree of variability, may enhance biodiversity within cereal food supply and deliver essential ingredients as grain and vegetable crops suitable for variable climatic conditions and also for people with allergies. Goals in improving cultivars of grain amaranth are similar to those in other grain crops - improvement and stabilization of the yield, increasing pest resistance, and improving harvestibility. The aim of this work was to combine radiation mutagenesis with biotechnology approaches to improve selected Amaranthus cultivars. For the experiments, two genotypes of Amaranthus sp. have been selected - Amaranthus cruentus 'Ficha' and hybrid 'K-433' which are characterized by a good seed quality and quantity, suitable for food production. The seeds were treated with 175 Gy. During the period of the project duration (10 December 1998-19 May 2003) the M1 - M5 generations were established. The phenological observations were performed during all vegetation periods and selection on desired traits was done. The negative plants were removed from the field. The weight of seeds per plant and weight of 1000 seeds (WTS) was recorded and statistically evaluated. Finally, as seed progeny of M4 generation, 48 samples of A. cruentus (irradiated) with WTS > 0.87g and 18 samples of K-433 (irradiated) with WTS > 0.75g were selected and used for establishment of M5 generation. In several samples of A. cruentus, the WTS reached 0.9-1.0g and in K-433 0.8-0.9g with an obvious tendency to stabilization of this trait when comparing them with the mother plants of the previous generation.

    Full Text Available Qualea grandiflora Mart. (Vochysiaceae, commonly known as "pau-terra", is an arborous species native to the Brazilian savannah which possess commercial interests, as it can be used either as an ornamental or as a medicinal plant. "Pau-terra" can also be used in the heterogeneous reforestation of areas which are destined for restoration of permanent preservation degraded areas. Propagation studies with this species are scarce, being necessary then further clarification regarding the factors that influences the germination process. In this context, the objective of this work was to evaluate the influence of different temperatures, substrates and light conditions on seed germination. We selected light brown seeds which were subjected to different interactions between temperatures (15-25, 20-30, 25 and 30°C, substrate (paper, sand and vermiculite and light (light and dark. All seeds were later dry-incubated at 32°C for 3, 6 and 12 hours. After treatments, seeds were kept in BOD at 58% RH and the following parameters were calculated: germination (%G and germination speed index (GSI; the formation of normal and abnormal seedlings and the number dead seeds. Interaction was observed for all variables. In the optimum temperature range, the seeds behaved as photoblastic neutral or indifferent. Under alternating temperatures, darkness enhanced the germination, especially when combined with the lower temperatures. We noted that the sowing in sand, at 25°C, allowed the maintenance of suitable combinations of germination and seedling development. With respect to desiccation tolerance, "pau-terra" seeds presented an orthodox behavior, with a linear increase of the vigor as function of drying.

    Full Text Available The objective of investigations carried out on the experimental field of the Faculty of Agriculture, Zagreb, in 2002, 2003 and 2004 was to compare green mass and dry matter yields of forage sorghum and amaranth, and the nutritional value of these two crops at several development stages. Investigations included two amaranth cultivars: ‘1008’ (Amaranthus hypochondriacus L. and ‘Koniz’ (Amaranthus hypochondriacus L. x Amaranthus hybridus L., and forage sorghum, hybrid Grazer N (Sorghum bicolor x S. sudanense. In all three trial years, forage sorghum gave the highest green mass and dry matter yield at the tasselling stage. In 2003, also amaranth, cultivar 1008, gave a high green mass yield at the flowering, which was in the same rank as forage sorghum. Decline of biomass quality was observed at later development stages due to a decrease in the concentration of crude and digestible proteins and an increase in NDF (neutral detergent fibre and ADF (acid detergent fibre concentrations. High quality of amaranth biomass was determined. Higher concentrations of crude and digestible proteins were found in amaranth aboveground biomass compared to forage sorghum while sorghum had a higher NDF concentration.

  7. Prevalence of airborne allergenic Amaranthus viridis pollen in seven different regions of Saudi Arabia

    International Nuclear Information System (INIS)

    Amaranthus pollen grains are known to have highly allergenic and potential cause of respiratory allergic diseases. Nevertheless, data on the prevalence of Amaranthus pollen in the environment is limited and almost non-existent for Saudi Arabia. We conducted an investigation to record the airborne incidence of A.viridis and other allergenic pollen in Al-Khobar, Dammam, Hail, Jeddah, Jizan, Qassim and Taif, using Burkard Volumetric Samplers. The samples were operated continuously for one year at each location. The data revealed A.viridis as one of the major components of outdoor airspora, constituting a maximum of 96% of total pollen counts in Hail, followed by Al-Khobar (89%), Jeddah (87%), Qassim (85%), Taif (84%), Dammam (83%) and Jizan (61%). These higher percentages contributed largely to the total weed pollen catch during August to November in all seven regions. In addition, the data also showed that A. virdis pollen were present throughout the year with distinct seasonal variations. The diel periodicities for at least five sites averaged over a year showed mid-day to early evening maxima. The maximum concentration approached 3000 mt. cube of air in October and 1827 mt. cube of air in September. The data also exhibited, a seasonal pattern, in their maximum appearance. Further studies related to biochemical and allergological aspects are needed to confirm the allergenic impact of Amaranthus pollen and sensitization in allergic individuals in the Kingdom of Saudi Arabia.

In tassonomia, variazioni morfologiche e morfometriche, spesso a carattere "locale", possono invalidare i tradizionali metodi di diagnosi utilizzati nell'attribuzione specifica. Inoltre criteri di discriminazione legati a caratteristiche corporee macroscopiche non sono applicabili nel caso in cui si disponga unicamente di resti quali peli, depositi fecali, tracce ematiche ecc. Nell'ambito dei mustelidi sono noti fenomeni di sovrapposizione dei caratteri diagnostici che rendono problematica l'identificazione delle specie, come nel caso di M. martes e M. foina. Negli ultimi anni l'identificazione di polimorfismi genetico-molecolari a scopo tassonomico ha permesso di dirimere numerosi casi incerti. In questo lavoro sono presentati i dati preliminari di uno studio volto ad identificare polimorfismi discriminanti le due specie di mustelidi considerate.

    Amaranthus, collectively known as amaranth, is an annual or short-lived perennial plant used as leafy vegetables, cereals and for ornamental purposes in many countries including India. During 2011, leaf samples of Amaranthus plants displaying leaf curling, leaf distortion, leaf crinkling and yellow leaf margins were collected from Banswara district, Rajasthan in India. Full-length clones of a monopartite begomovirus, a betasatellite and an alphasatellite were characterized. The complete nucleotide sequence of the isolated begomovirus features as a typical 'Old World' begomovirus with the highest nucleotide per cent identity with Chilli leaf curl virus and hence, considered as an isolate of Chilli leaf curl virus. The complete nucleotide sequences of betasatellite and alphasatellite possess maximum nucleotide identity with Tomato yellow leaf curl Thailand betasatellite and Chilli leaf curl alphasatellite, respectively. This is the first report of the association of chilli-infecting begomovirus and satellite molecules infecting a new host, Amaranthus, causing leaf curl disease. PMID:24368759

    Vegetables are the cheapest and most available sources of important proteins, minerals, vitamins, and essential amino protein. These vegetables are commonly used in Africa for the treatment of illness. This study evaluated the protective effects of Amaranthus caudatus and A. hybridus against sodium arsenite-induced toxicity in rats. The effects of sodium arsenite and/or the plant extracts were assessed using bone marrow micronucleus assay and by measuring the activities of tumour maker enzymes such as gamma glutamyl transferase (GGT) and alkaline phosphatase (ALP) in white albino Wister rats. The study showed that sodium arsenite significantly (P rats and were reverted back to near normal levels in rats pretreated with the plant extracts. A. caudatus and A. hybridus showed significant role in protecting the detoxifying enzymes; also, A. caudatus has a more protective effect on reducing the micronuclei formation when compared with A. hybridus. This study suggests that A. caudatus and A. hybridus possess anticarcinogenic effect. PMID:24174825

    2011-09-01

    The present study describes the behaviour of photosystem II (PSII) in Amaranthus hypochondriacus and Amaranthus hybridus under water stress conditions, assessed by the analyses of the polyphasic rise in chlorophyll a fluorescence (O-J-I-P). We determined the adaptive behaviour in relation to the regulation of the different functional and structural parameters of PSII, which was a direct and rapid response due to changes in soil water status indicated by a decrease in leaf water potential and relative water content. It allows for the identification of specific key or limiting chlorophyll fluorescence parameters which could be used to identify traits conveying tolerance. For the above partial processes of PSII function studied, it seems that A. hybridus remained the more stable upon water stress (after 17 days of withholding water), concerning the specific energy fluxes of absorption/reaction centre (ABS/RC) apparent (antenna size) and trapping/reaction centre (TR/RC) (maximum trapping flux), as well as the density of the reaction centres/cross section (RC/CS) and the phenomenological trapping flux/cross section (TR(o)/CS). It was clear that amaranth adjusts the non-photochemical (k(n)) deactivation constant of PSII and to a less extend also the photochemical (k(p)) deactivation constant by means of photoregulation, which forms the basis of the quenching of chlorophyll a fluorescence. Although drought stress caused the deactivation of RCs leading to a decrease in the density of active RCs, the plants compensated by increasing the efficiency of the conversion of trapped excitation energy to electron transport beyond Q(A) (efficiency of exciton trapping/reaction centre: ET(o)/TR(o)). Subsequent damage to PSII might be the reason for the slow, or lack of recovery, for most of the parameters measured. PMID:21696974

    1. Amaranthus spp. leaves contain high amounts of oxalates which affect the calcium absorption. This study was done to determine whether removal of the water-soluble oxalates from the leaves by cooking would reduce this deleterious effect. 2. Experimental work done with two types of basal diets on six adult male subjects has shown that the milk Ca absorption was low when leaves cooked without draining away the water were included in the diet. However when the soluble oxalates were removed by throwing away the water after cooking the leaves, the absorption of milk Ca was unaffected. PMID:568935

    Full Text Available ABSTRACT Occurrence and abundance of flea beetle species associated with Amaranthus spp. was studied in Slovakia with the aim to assess their potential as biological control agents. Insects were collected by sweeping/catching at 10 localities three times during the growing season. Together 13 species from the subfamily Alticinae were collected on A. retroflexus L. and A. caudatus L. plants by sweeping net. They were Altica oleracea (L., Chaetocnema concinna (Marsh., C. leavicolis Thoms., C. tibialis (Ill., Longitarsus longipennis Kutsch., L. melanocephalus Deg., L. nasturtii (F., L. pellucidus Foudras, Phyllotreta atra (F., P. cruciferae (Goeze, P. nigripes (F., P. vittula (Redt. and Psylliodes chrysocephala (L.. C. tibialis contained 41.17- 97.45 percent of all flea beetles population and it was found at all observed localities. It comprised 94.85-99.74 percent of flea beetles on cultivated A. caudatus. Another two Chaetocnema species, C. concinna and C. leavicollis did not overcome more than one percent of C. tibialis population. P. vittula was present at each locality. All the other species occurred on Amaranthus plants were probably concomitant. Species composition of subfamily Alticinae on cultivated species A. caudatus did not differ significantly from those on A. retroflexus.

    Full Text Available Background: The genus Amaranthus has potential activity as a hepatoprotective agent. Objective : The present pharmacological investigation focuses on evaluation of the efficacy of aqueous extract of roots of Amaranthus tricolor Linn. for their protection against paracetamol (PCM overdose induced hepatotoxicity . Materials and Methods: The aqueous extract of roots of A. tricolor Linn. was prepared and phytochemical screening was done. The biochemical investigation viz. serum glutamic oxaloacetate transaminase (SGOT, serum glutamic pyruvate transaminase (SGPT, alkaline phosphatase (ALP and total Bilirubin (TB was done against PCM-induced hepatotoxicity in wistar albino rats. The histopathological studies of liver were also done. Results: The phytochemical screening of the aqueous extract showed the presence of alkaloids, carbohydrates, flavanoids, amino acids, proteins, fixed oil, saponins and tannins, and phenolic compounds. Pretreatment with the aqueous extract of root significantly prevented the physical, biochemical, histological, and functional changes induced by paracetamol in the liver. The extract showed significant hepatoprotective effects as evidenced by decreased serum enzyme activities like SGPT, SGOT, ALP, and TB, which was supported by histopathological studies of liver. The aqueous extract showed significant hepatoprotective activity comparable with standard drug silymarin as well as hepatotoxin drug PCM. Conclusion: From these results, it is concluded that the A. tricolor has potential effectiveness in treating liver damage in a dose dependent manner.

  13. Detection of the genetic variability of amaranthus by rapd and issr markers

    International Nuclear Information System (INIS)

    RAPD and ISSR markers were used to analyse intra and inter-specific variability of 16 A. caudatus, 18 A. cruentus and 21 A. hypochondriacus accessions. The potential of both approaches was evaluated using three random and three microsatellite primers amplifying in total of 1126 (RAPD), respectively 1013 (ISSR) scorable fragments. Similarity values among accessions of three Amaranthus species ranged from 0.00 to 1.00 in both types of markers. Based on the intra-specific variability the polymorphism percentage varied from 70 to 100% (RAPD) or from 90 to 100% (ISSR) respectively. Resolving power (Rp) of ISSR primers have been higher (5.28 in average) in comparison to RAPD primers (4.84 in average). Percentage of distinguished accessions by ISSR and RAPD primers ranged from 29 to 89% (based on primer's type) and from 19 to 72%, respectively. Cluster analysis based on RAPD and ISSR data has shown the individual species separation except of three accessions. Two of A. caudatus genotypes originated from India clustered with A. hypochondriacus accessions and one of A. hypochondriacus genotype originated from Nepal clustered with A. cruentus accessions. This study has demonstrated, that a single primer marker systems as RAPD and ISSR are able to generate a sufficient level of informative characters for intra and inter-specific analysis of Amaranthus genus.

    This study investigates the bioactivity of tannin from amaranth (Amaranthus caudatus L.) extracts. The antioxidant activities of the extracts from amaranth leaves, flowers, and seeds were evaluated. Tannin from leaves of amaranth has been evaluated for superoxide scavenging activity by using DPPH and ABTS(+) analysis, reducing power, protective effect against H2O2-induced oxidative damage in L-132 and BNL-CL2 cells, and inhibition of superoxide radical effects on HL-60 cells. At a concentration of 100 μg/ml, tannin showed protective effects and restored cell survival to 69.2% and 41.8% for L-132 and BNL-CL2 cells, respectively. Furthermore, at the same concentration, tannin inhibited 41% of the activity of the superoxide radical on HL-60 cells and 43.4% of the increase in nitric oxide levels in RAW 264.7 cells. The expression levels of the antioxidant-associated protein SOD-1 were significantly increased in a concentration-dependent manner in RAW 264.7 cells treated with tannin from amaranth leaves. These results suggest that tannin from the leaves of Amaranthus caudatus L. is a promising source of antioxidant component that can be used as a food preservative or nutraceutical. PMID:25639718

    A lectin from the seeds of Amaranthus viridis Linn has been purified by affinity chromatography on asialofetuin-linked amino activated silica. Amaranthus viridis lectin (AVL) has a native molecular mass of 67 kDa. It is a homodimer composed of two 36.6 kDa subunits. The lectin gave a single band in non-denaturing PAGE at pH 4.5 and pH 8.3 and a single peak on HPLC size exclusion and cation exchange columns. The purified lectin was specific for both T-antigen and N-acetyl-D-lactosamine, markers for various carcinomas, in addition to N-acetyl-D-galactosamine, asialofetuin and fetuin. This lectin reacted strongly with red blood cells (RBCs) from human ABO blood groups and rat. It also reacted with rabbit, sheep, goat and guinea pig RBCs. The lectin is a glycoprotein having no metal ion requirement for its activity. Denaturing agents such as urea, thiourea and guanidine-HCl had no effect on its activity when treated for 15 minutes. AVL showed significant antiproliferative activity towards HB98 and P388D1 murine cancer cell lines. It also exerted antifungal activity against phytopathogenic fungi Botrytis cincerea and Fusarium oxysporum but not against Rhizoctonia solani, Trichoderma reesei, Alternaria solani and Fusarium graminearum.

    Full Text Available This paper describes a preliminary assessment of the nutraceutical value of Amaranthus cruentus (A. cruentus and Amaranthus hybridus (A. hybridus, two food plant species found in Burkina Faso. Hydroacetonic (HAE, methanolic (ME, and aqueous extracts (AE from the aerial parts were screened for in vitro antioxidant and xanthine oxidase inhibitory activities. Phytochemical analyses revealed the presence of polyphenols, tannins, flavonoids, steroids, terpenoids, saponins and betalains. Hydroacetonic extracts have shown the most diversity for secondary metabolites. The TLC analyses of flavonoids from HAE extracts showed the presence of rutin and other unidentified compounds. The phenolic compound contents of the HAE, ME and AE extracts were determined using the Folin–Ciocalteu method and ranged from 7.55 to 10.18 mg Gallic acid equivalent GAE/100 mg. Tannins, flavonoids, and flavonols ranged from 2.83 to 10.17 mg tannic acid equivalent (TAE/100 mg, 0.37 to 7.06 mg quercetin equivalent (QE /100 mg, and 0.09 to 1.31 mg QE/100 mg, respectively. The betacyanin contents were 40.42 and 6.35 mg Amaranthin Equivalent/100 g aerial parts (dry weight in A. cruentus and A. hybridus, respectively. Free-radical scavenging activity expressed as IC50 (DPPH method and iron reducing power (FRAP method ranged from 56 to 423 µg/mL and from 2.26 to 2.56 mmol AAE/g, respectively. Xanthine oxidase inhibitory activities of extracts of A. cruentus and A. hybridus were 3.18% and 38.22%, respectively. The A. hybridus extract showed the best antioxidant and xanthine oxidase inhibition activities. The results indicated that the phytochemical contents of the two species justify their traditional uses as nutraceutical food plants.

    Full Text Available Vegetables are the cheapest and most available sources of important proteins, minerals, vitamins, and essential amino protein. These vegetables are commonly used in Africa for the treatment of illness. This study evaluated the protective effects of Amaranthus caudatus and A. hybridus against sodium arsenite-induced toxicity in rats. The effects of sodium arsenite and/or the plant extracts were assessed using bone marrow micronucleus assay and by measuring the activities of tumour maker enzymes such as gamma glutamyl transferase (GGT and alkaline phosphatase (ALP in white albino Wister rats. The study showed that sodium arsenite significantly (P < 0.05 induced the formation of micronucleated polychromatic erythrocytes and the activities of ALP and GGT when compared with control. The levels of white blood cell, hemoglobin, and lymphocyte count were altered in sodium arsenite fed rats and were reverted back to near normal levels in rats pretreated with the plant extracts. A. caudatus and A. hybridus showed significant role in protecting the detoxifying enzymes; also, A. caudatus has a more protective effect on reducing the micronuclei formation when compared with A. hybridus. This study suggests that A. caudatus and A. hybridus possess anticarcinogenic effect.

    Forty seven of 150, 15-month-old long weaners died of an acute renal disease syndrome following introduction into an old maize field with a heavy stand of Amaranthus spp. The clinical syndrome was characterised by sudden onset neurological disease with ataxia and recumbency. Subcutaneous oedema, ascites and perirenal oedema with urine odour were the major gross necropsy findings. Renal histopathology revealed marked coagulative renal tubular necrosis of the proximal and distal straight tubules with intertubular haemorrhage. Acute renal failure and perirenal oedema has been described in cattle, pigs, horses and sheep associated with the ingestion of A. hybridus L. and A. retroflexus L. This perirenal oedema syndrome has been widely reported in the Americas, while in South Africa intoxication with the amaranths has only previously been associated with nitrate and possibly oxalate poisoning in cattle.

    A protozoan flagelate has recently been isolated from Amaranthus retroflexus. This plant grows near economically important crops in southeastern Spain, which are known to be parasitized by Phytomonas spp. The present study focuses on the characterization of the energy metabolism of this new isolate. These flagellates utilize glucose efficiently as their primary energy source, although they are unable to completely degrade it. They excrete ethanol, acetate, glycine, and succinate in lower amount, as well as ammonium. The presence of glycosomes was indicated by the early enzymes of the glycolytic pathway, one enzyme of the glycerol pathway (glycerol kinase), and malate dehydrogenase. No evidence of a fully functional citric-acid cycle was found. In the absence of catalase activity, these flagellates showed significant superoxide dismutase activity located in the glycosomal and cytosolic fractions. These trypanosomes, despite being morphologically and metabolically similar to other Phytomonas isolated from the same area, showed significant differences, suggesting that they are phylogenetically different species.

  14. Thermal properties of complexes of amaranthus starch with selected metal salts

    International Nuclear Information System (INIS)

    Metal cations (Cu(II), Fe(III), Mn(II), and Ni(II)) are ligated by amaranthus starch as proven by EPR spectra and conductivity measurements. The hydroxyl groups of starch are the coordination sites. The acetate and nitrate anions of the metal salts behave as bidentate ligands and reside in the inner coordination sphere of resulting polycenter Werner complexes. There is only a weak degeneration of orbitals of central metal ions caused by a shift of unpaired spin from the central atom to the ligand. The ligation of the central metal atoms resulted in a variation of the thermal stability, pathway, and rate of thermal decomposition of starch as proven by thermogravimetric (TG) and differential scanning calorimetric (DSC) measurements

    International Nuclear Information System (INIS)

    The radioprotective efficacy of aqueous extract of Rajgira (Amaranthus paniculatus) leaves against whole body gamma radiation was studied in Swiss albino mice. The oral administration of Rajgira extract at 800 mg/kg body weight/day for 15 consecutive days before whole body exposure to radiation was found to be effective with the LD50/30 values of 6.33 and 8.62 Gy for irradiation alone and Rajgira+irradiation group, respectively, giving a dose reduction factor of 1.36. This effect of Rajgira accompanied the increased endogenous spleen colonies and the spleen weight without any side effect or toxicity, as well as the modulation of the radiation-induced decrease of reduced glutathione and the radiation-induced increase in lipid peroxidation assessed in the liver and the blood.

    The herbicide glyphosate inhibits the plant enzyme 5-enolpyruvylshikimate3-phosphate synthase (EPSPS) in the aromatic amino acid (AAA) biosynthetic pathway. The physiologies of an Amaranthus palmeri population exhibiting resistance to glyphosate by EPSPS gene amplification (NC-R) and a susceptible population (NC-S) were compared. The EPSPS copy number of NC-R plants was 47.5-fold the copy number of NC-S plants. Although the amounts of EPSPS protein and activity were higher in NC-R plants than in NC-S plants, the AAA concentrations were similar. The increases in total free amino acid and in AAA contents induced by glyphosate were more evident in NC-S plants. In both populations, the EPSPS protein increased after glyphosate exposure, suggesting regulation of gene expression. EPSPS activity seems tightly controlled in vivo. Carbohydrate accumulation and a slight induction of ethanol fermentation were detected in both populations. PMID:26652930

  17. Thermal properties of complexes of amaranthus starch with selected metal salts

    Metal cations (Cu(II), Fe(III), Mn(II), and Ni(II)) are ligated by amaranthus starch as proven by EPR spectra and conductivity measurements. The hydroxyl groups of starch are the coordination sites. The acetate and nitrate anions of the metal salts behave as bidentate ligands and reside in the inner coordination sphere of resulting polycenter Werner complexes. There is only a weak degeneration of orbitals of central metal ions caused by a shift of unpaired spin from the central atom to the ligand. The ligation of the central metal atoms resulted in a variation of the thermal stability, pathway, and rate of thermal decomposition of starch as proven by thermogravimetric (TG) and differential scanning calorimetric (DSC) measurements.

    Three putative resistant Amaranthus retroflexus L. populations were collected in Heilongjiang province in China. Whole plant bioassays indicated high resistance (RI > 10) to imazethapyr in the three populations. In vitro acetolactate synthase (ALS) assays revealed that ALS from populations H3, H17 and H39 was less sensitive to imazethapyr inhibition compared to the susceptible population H76. The half-maximal inhibitory concentration (I50) values for H3, H17 and H39 were 14.83, 15.27 and 268 times greater, respectively, than that of the susceptible population H76. Three nucleotide mutations resulted in three known resistance-endowing amino acid substitutions, Ala-205-Val, Trp-574-Leu and Ser-653-Thr in the three resistant populations respectively. Therefore, ALS target-site mutations in resistant A. retroflexus could be responsible for imazethapyr resistance. PMID:26453229

    Full Text Available Amaranthus cruentus is a tropical leaf vegetable grown in most tropical regions of the world for its vegetable protein. The fresh matured leaves of the plant were harvested and sun dried until a moisture content of between 12-13% was obtained. The sun dried leaves (Amaranthus cruentus leaf meal, ACLM were milled and analysed for their proximate composition. Crude protein was 23.0%+0.55; crude fat, 5.4%+0.01; crude fibre, 8.8%+0.02; ash, 19.3%+0.01 and gross energy, 3.3+0.01kcal/g all on dry matter basis. Methionine and to a lesser extent, lysine, arginine, leucine and aspartate were high. The ACLM was incorporated into five formulated broiler starter diets at varying inclusion levels. The control diet 1 had no ACLM inclusion. All the six diets including control diet 1 were formulated isocaloric and isonitrogenous and fed to the experimental chicks (n = 540. Birds kept on diet 2 (5% ACLM inclusion level had the best average weight gain (WG of 372.9+29.94g/chick. The feed efficiency (FE value and the protein efficiency ratio (PER for birds on diet 2 were similar (P > 0.05 to values obtained for the reference diet. The nitrogen retention (NR and apparent nitrogen digestibility (AND values obtained for diet 2 were highest at 1.48+0.24gN/chick/day and 63.12%+10.28, respectively. Except for dressed weight and the back of chicken all the organs weights taken were similar (P > 0.05. Haematological examinations were similar (P > 0.05. Results generally indicated that ACLM could be a useful dietary protein source for broiler starter chicks at 5% inclusion level.

  2. Productivity and food value of Amaranthus cruentus under non-lethal salt stress

    Macler, Bruce A.; MacElroy, Robert D.

    Stress effects from the accumulation of metal salts may pose a problem for plants in closed biological systems such as spacecraft. This work examined the effects of salinity on growth, photosynthesis and carbon allocation in the crop plant, Amaranthus. Plants were germinated and grown in modified Hoagland's solution with NaCl concentrations of 0 to 1.0%. Plants received salt treatments at various times in development to assess effects on particular life history phases. For Amaranthus cruentus, germination, vegetative growth, flowering, seed development and yield were normal at salinities from 0 to 0.2%. Inhibition of these phases increased from 0.2 to 0.4% salinity and was total above 0.5%. 1.0% salinity was lethal to all developmental phases. Onset of growth phases were not affected by salinity. Plants could not be adapted by gradually increasing salinity over days or weeks. Water uptake increased, while photosynthetic CO2 uptake decreased with increasing salinity on a dry weight basis during vegetative growth. Respiration was not affected by salinity. After flowering, respiration and photosynthesis decreased markedly, such that 1.0% NaCl inhibited photosynthesis completely. Protein levels were unchanged with increasing salinity. Leaf starch levels were lower at salinities of 0.5% and above, while stem starch levels were not affected by these salinities. The evidence supports salt inhibition arising from changes in primary biochemical processes rather than from effects on water relations. While not addressing the toxic effects of specific ions, it suggests that moderate salinity per se need not be a problem in space systems.

    Full Text Available Amaranth is a crop with a potentially increasing cultivation area. Little information is available on amaranth cultivation in Mediterranean environments and in southern Italy. The aim of this study was to evaluate the agronomic traits and assess the grain and biomass yield responses of 11 genotypes belonging to 5 Amaranthus species, provided from the USDA-ARS, National Plant Germplasm System. There was wide diversity in agronomic traits among Amaranthus species and among genotypes within the same species. The accessions belonging to A. cruentus had the shortest growing cycle followed by A. hybridus, A. hypochondriacus, A. caudatus and, finally, A. hybrid that had the longest growing season. The A. cruentus accessions reached maturity more quickly than the other species. The total above-ground dry matter ranged from 15 to 23 t ha-1 with A. cruentus, A. hypochondriacus, and A. hybridus being the most productive. The stem plus branches dry matter was well correlated to the plant height (r2 = 0.75**. The tested amaranth genotypes showed appreciable biomass production that can thus be regarded as an interesting secondary product after seed harvesting. Grain yield and components varied among species and accessions. A. hypochondriacus showed the highest yield per plant (55.4 g followed by five accessions belonging to A. cruentus and A. hybridus (26.4 g on average. Considering together their shorter growing season and their higher grain production, the five accessions belonging to A. cruentus species appear to be better adapted to Mediterranean environments and southern Italy as compared to the other species.

    Full Text Available Nuestro José Martí, ejemplo de una formación humanística integral, escribió en una carta a María Mantilla:”Donde yo encuentro poesía mayor es en los libros de ciencia…” Martí vio la ciencia como un fenómeno social y consideró que el desarrollo científico técnico debía estar en función de la satisfacción de las necesidades de las grandes mayorías. Su sistemática voluntad  de cultivarse, de tratar de entender al mundo y no sólo de vivirlo, de razonarlo, fue el motor principal que llevaría a Martí a hacerse de una cultura científica y técnica poco común entre los hombres de su época. También el hecho de vivir durante muchos años en los Estados Unidos le permitió analizar con  profundidad y realismo la sociedad de la época, y por tanto llegó a tener una visión muy avanzada de la relación hombre – naturaleza - sociedad, llegando a convertirse en un gran divulgador de los avances de la ciencia y la técnica de aquella época. La originalidad del periodismo de nuevo tipo que inicia José Martí como vehículo para la divulgación científico - técnica encuentra una de sus más altas expresiones en la revista “La América”. Esta publicación había comenzado en abril de 1882, en Nueva York, bajo la dirección de Rafael de Castro Palomino, quien solicita la colaboración del poeta. A partir del mes de marzo de 1883, el Maestro redacta “La América” en su totalidad, desde los titulares hasta los artículos ensayísticos. Martí caracteriza “La América” como “periódico útil”, pues se dedicó a divulgar los adelantos de la industria, comercio y agricultura de los productores de la América del Norte, y en el avisador prudente de los compradores de la América del Sur. Este carácter de la publicación permite a José Martí tratar desde las páginas de “La América” los recientes descubrimientos científicos, la reseña detallada de las exposiciones que exhibían los últimos logros de la t

    Aiming at clarifying the interactions between Cs, Sr, and other mineral elements in the genus Amaranthus, this study adopted 33 different varieties of Amaranthus and investigated the concentrations of 23 mineral elements in shoots grown in the fields of Iino in Fukushima prefecture. Significant varietal effects were detected for all elements except Se, and degree of interspecies variation was highly element dependent. Among 23 elements, amaranths were less sensitive to the accumulation of Cs and Sr than most other mineral elements to the species level. There are six elements showing significant correlation with Cs, positive correlations between As, Rb, Al, Fe, Ni, and Cs, and negative correlation between Ba and Cs. Significant correlations between Ca, Mg, Mn, Zn, B, Ba, Cd, and Sr were detected, and all of the coefficients were positive. Cs and Sr did not present significant correlation, but they were both significantly correlated with Ba. By principal component analysis (PCA), the first and second principal components (PC1 and PC2) accounted for 23.2 and 20.3% of the total variance and associated with Cs and Sr, respectively. Both of the two species took up more Cs by promoting the influx of elements positively correlated with Cs into shoot, but at the same time, Amaranthus hypochondriacus (L.) Mapes 847 decreased the K and Ba uptake and Amaranthus powellii (S. Wats) subsp. Powellii inhibited the accumulation of Rb, Sr, and significantly correlated elements of Sr in shoot. This study is the first to pave the way for comprehension on ionome in amaranth shoot at the variety level. The results of this research provide the ionomic basis for implementing countermeasures in the field against the translocation of Cs (and potentially Sr) toward crops and food. PMID:25660261

The working principle is first introduced qualitatively, and the mathematical background is given that explains how the MART reconstruction can be improved on the basis of an improved first guess object obtained from the combination of non-simultaneous views reduced to the same time instant deforming the 3D objects by an estimate of the particle motion field. The performances of MTE are quantitatively evaluated by numerical simulation of the imaging, reconstruction and image correlation processes. The cases of two or more exposures obtained from time-resolved experiments are considered. The iterative application of MTE appears to significantly improve the reconstruction quality, first by decreasing the intensity of the ghost images and second, by increasing the intensity and the reconstruction precision for the actual particles. Based on computer simulations, the maximum imaged seeding density that can be dealt with is tripled with respect to the MART analysis applied to a single exposure. The analysis also illustrates that the maximum effect of the MTE method is comparable to that of doubling the number of cameras in the tomographic system. Experiments performed on a transitional jet at Re = 5000 apply the MTE method to double-frame recordings. The velocity measurement precision is increased for a system with fewer views (two or three cameras compared with four cameras). The ghost particles' intensity is also visibly reduced although to a lesser extent with respect to the computer simulations. The velocity and vorticity field obtained from a three

  4. Assessment of lead, cadmium, and zinc contamination of roadside soils, surface films, and vegetables in Kampala City, Uganda

    International Nuclear Information System (INIS)

    The relationship between traffic density and trace metal concentrations in roadside soils, surface films, and a selected vegetable weed, Amaranthus dubius Mart. Ex Thell., was determined in 11 farming sites along major highways around Kampala City in Uganda. Surface soil, atmospherically deposited surface films on windows, and leaves of Amaranthus dubius were sampled at known distances from the roads and analyzed for lead (Pb), zinc (Zn), and cadmium (Cd) using flame atomic absorption spectrophotometry. Atmospherically deposited trace metal particulates were sampled using window glass as an inert, passive collector. Total trace metal concentrations in soils ranged from 30.0±2.3 to 64.6±11.7 mg/kg Pb, 78.4±18.4 to 265.6±63.2 mg/kg Zn, and 0.8±0.13 to 1.40±0.16 mg/kg Cd. Total trace metal levels in soil decreased rapidly with distance from the road. Total Pb decreased with distance up to 30 m from the road, where it reached a background soil concentration of 28 mg/kg dry weight. The study found background values of 50 and 1.4 mg/kg for Zn and Cd in roadside soils, respectively. Similarly, Pb concentration in Amaranthus dubius leaves decreased with increasing distance from the road edge. The dominant pathway for Pb contamination was from atmospheric deposition, which was consistent with Pb concentrations in surface films. The mean Pb concentrations in leaves of roadside crops were higher than those in their respective roots, with the highest leaf-to-root ratio observed in the Brassica oleraceae acephala group. The lowest Pb and Zn concentrations were found in the fruit compared to the leaves of the same crops. Leaves of roadside vegetables were therefore considered a potential source of heavy metal contamination to farmers and consumers in urban areas. It is recommended that leafy vegetables should be grown 30 m from roads in high-traffic, urban areas

  16. Synthesis of polyols from Mabea fistulifera Mart. (Euphorbiaceae) oil

    International Nuclear Information System (INIS)

    Mabea fistulifera Mart. (Euphorbiaceae) is an arboreal plant with height varying from 5 to 14 m, typical of secondary vegetation of sandy lands, mainly savannah. In Brazil, it is found in the Rio de Janeiro, Minas Gerais and Sao Paulo States. Soxhlet extraction of M. fistulifera seeds with hexane provided an oil rich in triacylglycerides of linolenic and linoleic acids, presenting iodine index of 182.15 g of I2 per 100 g of oil. In this study, the synthesis of polyols from M. fistulifera oil using an in situ hydroxylation procedure is described. Univariate assays were applied to determine the optimal reaction time of 720 min. In addition, a 22 factorial central composite design was carried out containing 12 experimental assays that allowed the investigation of different molar ratios of the reagents used in polyol synthesis, as well as the applicability of polyols for the preparation of rigid polyurethanes.

    International Nuclear Information System (INIS)

    Decoction of roots of the Amazonian palm acai (Euterpe precatoria Mart.) is widely used by Brazilian and Peruvian people as an anti-inflammatory, to heal kidney and liver diseases and against snake bites. In this study, the antioxidant activity of extracts and flavonoids (quercetin, catechin, epicatechin, rutin and astilbin) isolated from roots and leaf stalks of E. precatoria was investigated using β-carotene in TLC plates and DPPH radical scavenging in a spectrophotometric bioassay. All extracts and flavonoids showed activity. Also, the cytotoxic activity of these extracts was evaluated by the brine shrimp (Artemia salina) larvicide bioassay and was lower than that of lapachol, used as control. The presence of flavonoids and sitosterol-3-O-β-D-glucopyranoside in the extracts can justify the use of the plant in traditional medicine. (author)

    CERN Document Server

    Rodrigues, Wendell; Dekeyser, Jean-Luc

    2011-01-01

    Nowadays, several industrial applications are being ported to parallel architectures. These applications take advantage of the potential parallelism provided by multiple core processors. Many-core processors, especially the GPUs(Graphics Processing Unit), have led the race of floating-point performance since 2003. While the performance improvement of general- purpose microprocessors has slowed significantly, the GPUs have continued to improve relentlessly. As of 2009, the ratio between many-core GPUs and multicore CPUs for peak floating-point calculation throughput is about 10 times. However, as parallel programming requires a non-trivial distribution of tasks and data, developers find it hard to implement their applications effectively. Aiming to improve the use of many-core processors, this work presents an case-study using UML and MARTE profile to specify and generate OpenCL code for intensive signal processing applications. Benchmark results show us the viability of the use of MDE approaches to generate G...

    Full Text Available Data warehousing is one of the latest trends in computing environment and information technology applications. A data warehouse is a system that extracts, cleans and delivers source data into dimensionaldata store and then supports and implements querying and analysis for the purpose of decision making. From a data warehouse, data flows to various departments for their customized decision support systems.These individual departmental components are called data marts. A data mart is a set of dimensional tables supporting a business process. Data marts contain all atomic detail needed to support drilling down to the lowest level. Every company or organization in the world has a website. Beneath each web site are web logs that record every object either posted to or served from the web server. Web logs are important because they reveal the user traffic on the web site. The activity of parsing web logs and storing the results in a data mart to analyze customer activity is known as click stream data warehousing. The web mart - database schema is designed to make the underlying data structure more comprehensible to users and to simplify the query process. The recommended approach for data warehouse data modeling is to follow a Dimensional Modeling approach - Star Schema. We explore the design and analysis of web mart and its relevance today at minute level.

    Full Text Available Sensitisation to Amaranthus retroflexus pollen is very common in tropical and subtropical countries. In this study we aimed to produce a recombinant allergenic Ole e 1-like protein from the pollen of this weed. To predict cross-reactivity of this allergen (Ama r 1 with other members of the Ole e 1-like protein family, the nucleotide sequence homology of the Ama r 1 was investigated. The expression of Ama r 1 in Escherichia coli was performed by using a pET-21b(+ vector. The IgE-binding potential of recombinant Ama r 1 (rAma r 1 was evaluated by immunodetection and inhibition assays using 26 patients’ sera sensitised to A. retroflexus pollen. The coding sequence of the Ama r 1 cDNA indicated an open reading frame of 507 bp encoding for 168 amino acid residues which belonged to the Ole e 1-like protein family. Of the 26 serum samples, 10 (38.46% had significant specific IgE levels for rAma r 1. Immunodetection and inhibition assays revealed that the purified rAma r 1 might be the same as that in the crude extract. Ama r 1, the second allergen from the A. retroflexus pollen, was identified as a member of the family of Ole e 1-like protein.

    The objective of this study was to identify the major peptides generated by the in vitro hydrolysis of Amaranthus cruentus protein and to verify the effect of these peptides on the activity of 3-hydroxy-3-methyl-glutaryl-CoA reductase (HMG-CoA reductase), a key enzyme in cholesterol biosynthesis. A protein isolate was prepared, and an enzymatic hydrolysis that simulated the in vivo digestion of the protein was performed. After hydrolysis, the peptide mixture was filtered through a 3 kDa membrane. The peptide profile of this mixture was determined by reversed phase high performance chromatography (RP-HPLC), and the peptide identification was performed by LC-ESI MS/MS. Three major peptides under 3 kDa were detected, corresponding to more than 90% of the peptides of similar size produced by enzymatic hydrolysis. The sequences identified were GGV, IVG or LVG and VGVI or VGVL. These peptides had not yet been described for amaranth protein nor are they present in known sequences of amaranth grain protein, except LVG, which can be found in amaranth α‑amylase. Their ability to inhibit the activity of HMG-CoA reductase was determined, and we found that the sequences GGV, IVG, and VGVL, significantly inhibited this enzyme, suggesting a possible hypocholesterolemic effect.

  14. Barley (Hordeum vulgare) and Kiwicha (Amaranthus caudatus) Improvement by Mutation Induction in Peru

    International Nuclear Information System (INIS)

    In order to increase food availability and household incomes of families in the Andean region of Peru, a mutation induction method was applied to improve barley (Hordeum vulgare) and kiwicha (Amaranthus caudatus) cultivars. Barley cultivar Buenavista was treated with 200 and 300Gy inducing different kinds of mutations. Twenty promising mutant lines were selected and have been evaluated at the national trials. From them Mbv-Earlier, from 300Gy dose was selected and released in 2006 as a new cultivar denominated Centenario. This cultivar has a high yield potential (5,552 kg/ha), resistance to stripe rust (P. striiformis f sp hordei) and better food quality than the parental cultivar. Kiwicha traditional cultivar Seleccion Ancash treated with 400Gy , identified a higher yield mutant denominated Centenario Cultivar. At farmer location in the coast the yield has a variation of 3,500 to 5,500 kg/ha and in the highland from 2,500 to 3,700 kg/ha. The better yield potential, tolerance to Sclerotinia sp, color and size of its grains have contributed in the preference of Centenario over other commercial cultivars. (author)

Their ability to inhibit the activity of HMG-CoA reductase was determined, and we found that the sequences GGV, IVG, and VGVL, significantly inhibited this enzyme, suggesting a possible hypocholesterolemic effect.

    In order to study the growth promotion behavior of sodium alginate (SA) on vegetable (red amaranth, Amaranthus cruentus L.), 3% aqueous solution of SA was irradiated by {gamma}-radiation (Co-60) of various total doses (12.5-50.0 kGy) at a dose rate of 3.5 kGy/h. Viscosity of the irradiated SA was found to decrease with increase in the radiation dose. The average molecular weight was also decreased from 10{sup 4} to 10{sup 3} orders. Red amaranth was cultivated in 18 different individual plots and SA solution (150 ppm) was applied on red amaranth after 10 days of seedlings at every 6 days interval. The morphological characters of vegetables were studied randomly in different unit plots. The irradiated SA of 37.5 kGy at 150 ppm solution showed the best performance. Dry matter of red amaranth significantly increased at 37.5 kGy of irradiated alginate treatment which was about 50% higher than that of the untreated samples. The effect of SA on red amaranth was found significant increase; i.e. plant height (17.8%), root length (12.7%), number of leaf (5.4%) and maximum leaf area (2%) compared to that of the control vegetative plant production.

    Sensitisation to Amaranthus retroflexus pollen is very common in tropical and subtropical countries. In this study we aimed to produce a recombinant allergenic Ole e 1-like protein from the pollen of this weed. To predict cross-reactivity of this allergen (Ama r 1) with other members of the Ole e 1-like protein family, the nucleotide sequence homology of the Ama r 1 was investigated. The expression of Ama r 1 in Escherichia coli was performed by using a pET-21b(+) vector. The IgE-binding potential of recombinant Ama r 1 (rAma r 1) was evaluated by immunodetection and inhibition assays using 26 patients' sera sensitised to A. retroflexus pollen. The coding sequence of the Ama r 1 cDNA indicated an open reading frame of 507 bp encoding for 168 amino acid residues which belonged to the Ole e 1-like protein family. Of the 26 serum samples, 10 (38.46%) had significant specific IgE levels for rAma r 1. Immunodetection and inhibition assays revealed that the purified rAma r 1 might be the same as that in the crude extract. Ama r 1, the second allergen from the A. retroflexus pollen, was identified as a member of the family of Ole e 1-like protein. PMID:26925110

    This study was designed to evaluate the protective effect of water extract of Amaranthus lividus L. (A. lividus) (Amaranthaceae) on carbon tetrachloride (CCl4)-induced toxicity in kidneys of rats. For this purpose, male albino Wistar rats were pretreated with A. lividus (250 and 500 mg/kg body weight (b.w.)) daily for 9 days and a single dose of CCl4 was applied intraperitoneally (50% in olive oil; 1.5 mL/kg b.w.) on the 10th day. All rats were killed 24 h after CCl4 administration, and kidneys were excised and used for determination of histopathological and biochemical parameters. CCl4 administration caused a remarkable increase in lipid peroxidation (LPO) and glutathione levels and glutathione-S-transferase, glutathione peroxidase, glutathione reductase, superoxide dismutase, myeloperoxidase (MPO) activities and a decrease in catalase (CAT) activity when compared to the control group. Pretreatment with A. lividus (250 and 500 mg/kg b.w.) significantly prevented the elevation in LPO level and MPO activity as well as protected the decrease in CAT activity but did not alter other biochemical parameters. The protective effect of A. lividus was further evident through the decreased histological alterations in kidneys. In conclusion, this study has indicated that A. lividus possesses protective and antioxidant effects against CCl4-induced oxidative kidney damage. PMID:25415872

    Experiments were conducted to confirm imazethapyr resistance in redroot amaranth (Amaranthus retroflexus L.) and study the target-site based mechanism for the resistance. Whole-plant response experiments revealed that the resistant (R) population exhibited 19.16 fold resistance to imazethapyr compared with the susceptible (S) population. In vitro ALS activity assay demonstrated that the imazethapyr I50 value of the R population was 21.33 times greater than that of the S population. However, qRT-PCR analysis revealed that there is no difference in ALS gene expression between the R and S populations. Sequence analysis revealed an Asp-376-Glu substitution in ALS in the R population. In order to verify that the imazethapyr resistance was conferred by Asp-376-Glu mutation, the ALS-R and ALS-S genes were fused to the CaMV 35S promoter and introduced into Arabidopsis respectively. The expression of ALS-R in transgenic Arabidopsis plants exhibited 13.79 fold resistance to imazethapyr compared to ALS-S transgenic Arabidopsis. PMID:26969434

  1. The transfer parameter of environmental 85Sr radiostrontium trough soil - spinach plant (Amaranthus sp.) Pathway

    International Nuclear Information System (INIS)

    The radionuclide transfer from soil to crop is a pathway of the radionuclide to contaminate human body. Soil plant interaction can be examined by several parameter such as transfer factor (Ft) and transfer rate coefficient (k12). An experiment about radiostrontium transfer from soil to crop had been conducted to determine the plant ability in radiostrontium accumulation for human internal doses assessment. Crop represented by commonly consumed by people, spinach (Amaranthus sp.), was cultivated in soil contaminated with 85Sr for about 2 months. Every five days the soil and plants were sampled, dried, and the 85Sr activities were measured using gamma spectrometer. The measurement results showed that the spinach crop were able to absorb and accumulate 85Sr. The Ft value obtained from this experiment is about 3, whereas the k12 values are 9.99 x 10-3 day-1 and 9.98 x 10-3 day-1, for 041 days, respectively. The 85Sr soil - plant transfer parameter is expected to be used for radiological impact assessment in the case of Sr radionuclide contamination in soil. The obtained Ft and k12 can be use for predicting Sr radioactivities in edible parts of plants in certain period after soil contamination with radiostrontium. (author)

    Isocitrate lyase (EC 4.1.3.1) catalyzes the reversible conversion of d-isocitrate to succinate and glyoxylate. It is usually associated with the glyoxylate cycle in glyoxysomes, although the non-glyoxysomal form has been reported and its relation to interconversion of organic acids outside the glyoxylate cycle suggested. We investigated the expression of two isocitrate lyase genes and activities of the glyoxysomal (ICL1) and cytosolic (ICL2) forms of isocitrate lyase in amaranth (Amaranthus caudatus L.) seedlings. Both forms were separated and purified. The cytosolic form had a low optimum pH (6.5) and was activated by Mn(2+) ions, while Mg(2+) was ineffective, and had a lower affinity to d, l-isocitrate (Km 63 μM) as compared to the glyoxysomal form (optimum pH 7.5, K(m) 45 μM), which was activated by Mg(2+). The highest ICL1 activity was observed on the 3rd day of germination; then the activity and expression of the corresponding gene decreased, while the activity of ICL2 and gene expression increased to the 7th day of germination and then remained at the same level. It is concluded that the function of ICL1 is related to the glyoxylate cycle while ICL2 functions independently from the glyoxylate cycle and interconverts organic acids in the cytosol.

    In this study, tea saponin (TS) was extracted from tea camellia seed by microwave-assisted extraction. The potential of TS was compared with ethylenediaminetetracetic acid (EDTA), which is used as a common chemical agent to enhance uptake of cadmium (Cd) by Amaranthus caudatus, an ornamental plant in the natural vegetation of Turkey under pot conditions. The enrichment coefficient (EC) and translocation factor (TF) values were calculated to evaluate the removal efficiency of the TS and EDTA. The results showed that an increase in both TS and EDTA concentration significantly increased Cd uptake by A. caudatus, accumulating Cd in different parts of the plant. Higher EC and TF values obtained from stems, leaves, and inflorescences of A. caudatus showed that this plant might be cultivated and used as a hyperaccumulator in the uptake of Cd from the Cd contaminated soils. Thus, the present technique can efficiently reduce the metal load in the food chain; hence, it could be applied in catchment areas of urban cities where Cd contamination has become an unavoidable factor.

    Full Text Available Forty three vegetable amaranth (Amaranthus tricolor L. genotypes selected from different eco-geographic regions of Bangladesh were evaluated during 3 years (2012-2014 for genetic variability, heritability and genetic association among mineral elements and quality and agronomic traits in randomized complete block design (RCBD with five replications. The analysis showed that vegetable amaranth is a rich source of K, Ca, Mg, proteins and dietary fibre with average values among the 43 genotypes (1.014%, 2.476%, 2.984, 1.258% and 7.81%, respectively. Six genotypes (VA13, VA14, VA16, VA18, VA26, VA27 showed a biological yield >2000 g/m2 and high mineral, protein and dietary fibre contents; eleven genotypes had high amount of minerals, protein and dietary fibre with above average biological yield; nine genotypes had below average biological yield but were rich in minerals, protein and dietary fibre. Biological yield exhibited a strong positive correlation with leaf area, shoot weight, shoot/root weight and stem base diameter. Insignificant genotypic correlation was observed among mineral, quality and agronomic traits, except K vs. Mg, protein vs. dietary fibre and stem base diameter vs. Ca. Some of these genotypes can be used for improvement of vegetable amaranth regarding mineral, protein and dietary fibre content without compromising yield loss.

  6. Leaf cuticle variations in amaranthus spinousus as indicators of environmental pollution

    International Nuclear Information System (INIS)

    Investigation of the leaf epidermal characteristics of Amaranthus spinosus from polluted and non-polluted populations revealed that the stomatal pores of the leaves of the plants of the polluted areas were closed whereas those of the non-polluted areas were open. Mean length x mean width of stomatal pores on the upper leaf surface were 0.86 micro x 0.43 micro and 1.23 micro x 0.45 micro on the lower leaf surface of the non polluted microhabitats. Also, the leaves of the polluted population were smaller than those of the non-polluted population. The average leaf area of the plants of the Polluted population was 7.64 cm/sub -2/ against 12.13 cm/sub 2/ of the plants of the non-polluted areas. The results were attributed to the combined effects of air pollutant that predominated roadsides from where the samples were taken. Thus it is inferred that this plant could serve as bio-indicator of air pollution. (author)

    Full Text Available Anatomical studies were carried out on the leaves, stems and roots of Amaranthus hybridus subjected to irrigation of 10%, 20%, 30% and 40% concentrations of pharmaceutical effluents to identify the responses of this plant to the treatment. Leaf structures of A. hybridus showed no significant change due to the effect of the effluents. Significant reduction was observed in the trichome density and number of epidermal cells at the adaxial surface as from the 20% effluent concentration upward (pA. hybridus with varied modifications from 20% effluent concentration upward at both leaf surfaces. Vessels and phloem cells in the stems and roots of A. hybridus were seriously affected by the effluent. Vessel walls were thickened and their width reduced significantly as from 20% effluent concentration upward while phloem cells experienced progressive loss of structural integrity from the same concentration (20% upward in both the stems and roots. This study showed that the pharmaceutical effluents have toxic effect on A. hybridus and the effects were more pronounced as from 20% concentration.

    Institute of Scientific and Technical Information of China (English)

    2003-01-01

    An antimicrobial peptide gene from Amaranthus hypochondriacus, Ah-AMP, was amplified by PCR and cloned. Sequence analysis results revealed that this gene is 261 bp in length encoding a precursor polypeptide of 87 amino acid residues. Ah-AMP gene was inserted in the binary vector pBin438 to construct a plant expression vector pBinAH916. Leave explants of Nicotiana tabacum var. SR1 were transformed with Agrobacterium tumefaciens LBA4404 harboring the above expression vector. Results from PCR, Southern and Northern blot analyses confirmed that the Ah-AMP gene had been integrated into the tobacco genome and was transcribed at mRNA level. Two bacterial-resistant transgenic plants were selected by inoculating the plants with Pseudomonas solanacearum and statistic analysis of two T1 lines showed that the resistance increased by 2.24 and 1.62 grade and the disease index decreased by 49.6% and 37.3% respectively when compared with the non-transformed control plants SR1. The results from challenging the plants with inoculums of Phytophthora parasitica showed that the symptom development was delayed and disease index was significantly reduced. These results suggest that Ah-AMP gene may be a potentially valuable gene for genetic engineering of plant for disease-resistance.

    Full Text Available We evaluated the effects of defatted amaranth (Amaranthus caudatus L. snacks on plasma lipids in moderate hypercholesterolemic patients. Twenty-two subjects [30-65 years old, 11 males, with total cholesterol (TC > 240 mg.dL-1, low-density cholesterol (LDL-c 160-190 mg.dL-1 and plasma triglycerides (TG < 400 mg.dL-1] were randomized in a double blind clinical trial to receive an amaranth snack (50 g/day or equivalent corn snack (placebo for 2 months. There were no differences between amaranth and placebo on TC and LDL-c, and TG respectively: -8.4 and -5.7% (p = 0.17; -12.3 and -9.7% (p = 0.41 and -0.6 and -7.3% (p = 0.47. However, amaranth snacks significantly reduced high-density cholesterol (HDL-c: -15.2 vs. -4% (p = 0.03. In conclusion, the intake of 50 g of extruded amaranth daily during 60 days did not significantly reduce LDL-c in moderate hypercholesterolemic subjects; furthermore there was a significant reduction in HDL-c. Studies with greater number of subjects and greater quantity of this food are necessary to test the effects of amaranth on lipid metabolism in humans.

  10. Sodium stimulates growth of Amaranthus tricolor L. plants through enhanced nitrate assimilation

    International Nuclear Information System (INIS)

    Effects of Na application on the capacity of No3- assimilation were studied in Na-deficient Amaranthus tricolor L. cv Tricolor plants. On day 30 after germination, Na-deficient A. tricolor plants received either 0.5 millimolar NaCl or KCl. The level of nitrate reductase activity doubled within 24 hours by the addition of Na and the enhanced level was maintained thereafter. When the plants were exposed to 2 millimolar 15NO3-, total 15N taken up by the plants was greater in the Na-treated plants than in the K-treated plants within 24 hours of the Na treatment. Incorporation of 15N into the 80% ethanol-insoluble nitrogen fraction of the Na-treated plants in the light period was about 260% of those of the K-treated plants indicating greater capacity of NO3- assimilation in the Na-treated plants. From these results, it was demonstrated that Na application to the Na-deficient A. tricolor plants promoted NO3- reduction and its subsequent assimilation into protein, resulting in growth enhancement

    A 30-residue antimicrobial peptide Ar-AMP was isolated from the seeds of amaranth Amaranthus retroflexus L. essentially by a single step procedure using reversed-phase HPLC, and its in vitro biological activities were studied. The complete amino acid sequence of Ar-AMP was determined by Edman degradation in combination with mass spectrometric methods. In addition, the cDNA encoding Ar-AMP was obtained and sequenced. The cDNA encodes a precursor protein consisting of the N-terminal putative signal sequence of 25 amino acids, a mature peptide of 30 amino acids and a 34-residue long C-terminal region cleaved during post-translational processing. According to sequence similarity the Ar-AMP belongs to the hevein-like family of antimicrobial peptides with six cysteine residues. In spite of the fact that seeds were collected in 1967 and lost their germination capacity, Ar-AMP retained its biological activities. It effectively inhibited the growth of different fungi tested: Fusarium culmorium (Smith) Sacc., Helminthosporium sativum Pammel., King et Bakke, Alternaria consortiale Fr., and Botrytis cinerea Pers., caused morphological changes in Rhizoctonia solani Kühn at micromolar concentrations and protected barley seedlings from H. sativum infection.

    Full Text Available The anatomy of stems and leaves of two populations of the weed species Amaranthus retroflexus L. (red-root amaranth (pop. AMARE1 having green stems covered in sparse hairs and pop. AMARE2 with green but notably dense stem hairs was analysed in order better to understand the uptake and translocation of herbicides that could be indicative of the species’ evolving resistance to herbicides. Samples of the two populations (AMARE1 and AMARE2 were collected from arable land of the Institute of Maize Research at Zemun Polje in 2006. Sampling was performed at the stage of full vegetative growth of plants.Permanent microscoping preparations were made to measure and analyze elements of the anatomy of stems (stem epidermis, cortex, collenchyma, central cylinder and diameter and leaves (leaf epidermis upper surface and underside, mesophyll, leaf thickness and bundle sheath thickness.Both analysed populations of A. retroflexus, morphologically characterized by different density of stem hairiness, were found to have a typical structure of herbaceous dicots. The stem had three distinctive zones: epidermis, cortex and central cylinder. Amaranth leaves have dorsoventral structure, i.e. their upper surface and underside can be differentiated. The results indicated high and very high significance of differences found in stem anatomy between the two analysed populations, while leaf anatomy was not found to display significant differences other than in mesophyll thickness.

El género Amaranthus está distribuido a lo largo de México. A. cruentus y A. hypochondriacus se distribuyen en la parte centro sur del país, mientras que A. powellii está distribuido del centro al norte de México. Por otro lado, A. hybridus se puede cultivar prácticamente en todo México, por lo que fue la especie que presentó la mayor adaptación en comparación a las otras tres especies que mostraron una distribución más limitada. De acuerdo con la hipótesis que A. hybridus puede ser el ancestro más probable de A. cruentus y según los resultados obtenidos en este estudio, esta hipótesis podría ser cierta debido que en toda la distribución de A. cruentus está presente A. hybridus. Cabe mencionar, sobre la hipótesis que A. hypochondriacus puede ser un híbrido entre A. cruentus y A. powellii, se puede concluir que es cierta ya que A. hypochondriacus presentó un patrón de variación latitudinal parecido a A. powellii y un patrón de variación altitudinal similar a A. cruentus; además que todas ellas convergen en el Valle de México.The aim of this work was to obtain the distribution patterns of Amaranthus cruentus, Amaranthus hypochondriacus and its wild relatives using Gorgraphic Information Systems, as well as creating a geographic variation pattern of the areas in which they are found.

    Highlights: • Similarities and differences between DCS and MARTe. • Identifies the state-of-the-art in terms of software frameworks for fusion control. • Interfaces developed for realtime and non-realtime communication between DCS and MARTe. • An algorithm replicated in DCS and MARTe produces identical results and good performance. • The start of collaboration to develop a new framework for ITER PCS. - Abstract: Fusion experiments place high demands on real-time control systems. Within the fusion community two modern framework-based software architectures have emerged as powerful tools for developing algorithms for real-time control of complex systems while maintaining the flexibility required when operating a physics experiment. The two frameworks are known as DCS (Discharge Control System), from ASDEX Upgrade and MARTe (Multithreaded Application Real-Time executor), originally from JET. Based on the success of DCS and MARTe, ITER has chosen to develop a framework architecture for its Plasma Control System which will adopt major design concepts from both the existing frameworks. This paper describes a coupling of the two existing frameworks, which was undertaken to explore the degree of similarity and compliance between the concepts, and to extend their capabilities. DCS and MARTe operate in parallel with synchronised state machines and a common message logger. Configuration data is exchanged before the real-time phase. During the real-time phase, structured data is exchanged via shared memory and an existing DCS algorithm is replicated within MARTe. The coupling tests the flexibility and identifies the respective strengths of the two frameworks, providing a well-informed basis on which to move forward and design a new ITER real-time framework.

    2014-10-15

    We assessed phylogeny of sable (Martes zibellina, Linnaeus, 1758) by sequence analysis of nearly complete, new mitochondrial genomes in 36 specimens from different localities in northern Eurasia (Primorye, Khabarovsk and Krasnoyarsk regions, the Kamchatka Peninsula, the Kuril Islands and the Urals). Phylogenetic analysis of mtDNA sequences demonstrates that two clades, A and BC, radiated about 200-300 thousandyears ago (kya) according to results of Bayesian molecular clock and RelTime analyses of different mitogenome alignments (nearly complete mtDNA sequences, protein-coding region, and synonymous sites), while the age estimates of clades A, B and C fall within the Late Pleistocene (~50-140 kya). Bayesian skyline plots (BSPs) of sable population size change based on analysis of nearly complete mtDNAs show an expansion around 40 kya in the warm Karganian time, without a decline of population size around the Last Glacial Maximum (21 kya). The BSPs based on synonymous clock rate indicate that M. zibellina experienced demographic expansions later, approximately 22 kya. The A2a clade that colonized Kamchatka ~23-50 kya (depending on the mutation rate used) survived the last glaciation there as demonstrated by the BSP analysis. In addition, we have found evidence of positive selection acting at ND4 and cytochrome b genes, thereby suggesting adaptive evolution of the A2a clade in Kamchatka. PMID:25110108

  6. Rural maternity care: can we learn from Wal-Mart?

    In many countries rural maternity care is under threat. Consequently rural pregnant women will have to travel further to attend larger maternity units to receive care and deliver their babies. This trend is not dissimilar from the disappearance of other rural services, such as village shops, banks, post offices and bus services. We use a comparative approach to draw an analogy with large-scale supermarkets, such as the Wal-Mart and Tesco and their effect on the viability of smaller rural shops, depersonalisation of service and the wider community. The closure of a community-maternity unit leads to women attending a different type of hospital with a different approach to maternity care. Thus small community-midwifery units are being replaced, not by a very similar unit that happens to be further away, but by a larger obstetric unit that operates on different models, philosophy and notions of risk. Comparative analysis allows a fresh perspective on the provision of rural maternity services. We argue that previous discussions focusing on medicalisation and change in maternity services can be enhanced by drawing on experience in other sectors and taking a wider societal lens.

    Full Text Available In higher education such as university, academic is becoming major asset. The performance of academic has become a yardstick of university performance. Therefore it's important to know the talent of academicians in their university, so that the management can plan for enhancing the academic talent using human resource data. Therefore, this research aims to develop an academic talent model using data mining based on several related human resource systems. In the case study, we used 7 human resource systems in one of Government Universities in Malaysia. This study shows how automated human talent data mart is developed to get the most important attributes of academic talent from 15 different tables like demographic data, publications, supervision, conferences, research, and others. Apart from the talent attribute collected, the forecasting talent academician model developed using the classification technique involving 14 classification algorithm in the experiment for example J48, Random Forest, BayesNet, Multilayer perceptron, JRip and others. Several experiments are conducted to get the highest accuracy by applying discretization process, dividing the data set in the different interval year (1,2,3,4, no interval and also changing the number of classes from 24 to 6 and 4. The best model is obtained 87.47% accuracy using data set interval 4 years and 4 classes with J48 algorithm.

    Full Text Available Combretum leprosum Mart. is a tree species native of the Caatinga, used in the restoration of degraded areas and in folk medicine. Thus, this research aimed to evaluate the germination and vigor of the seeds subjecting them to different pre-germinative treatments, temperatures and substrates. In the first experi- ment, we tested the pre-germinative treatments: mechanical scarification with sandpaper, chemical scarification with H2SO4 for 1, 5, 10 and 20 minutes, immersion in water at 80 oC and imbibition in distilled water for 24 hours, beyond of the control. In the second experiment, after treatment of imbibition in water for 24 hours, the experimental design was completely randomized in a factorial 5 x 4 (five substrates: into paper, sand, coconut fiber, vermiculite and paper towel organized in the form of rolls; and four temperatures: 25, 30, 35 and 20-30 oC. The following parameters were evalueted: seed moisture content, germination, germination speed index, first germination count and seedling length and dry matter weight. The seeds of Combretum leprosum have not coat dormancy. However, pre-germinative treatments of mechanical scarification with sandpaper and imbibi- tion in water for 24 hours allows better expression of seeds vigor. The paper towel and the temperatures of 25, 30 and 20-30 oC provide adequate conditions for evaluating the germination of Combretum leprosum seeds.

Microscopía sobre Buenos Aires, an essay by Ezequiel Martínez Estrada from 1940, as a reservoir of extremely diverse currents in the literature on Buenos Aires, containing many different figurations of the city. It also seeks to comprehend how the representations of the city were formed and from where they originated, as well as the ways in which the battles of the 'third culture' - in Wolf Lepenies's definition of sociological thought, forever wavering in the attraction/opposition between science and literature - were manifested in the context of urban Argentina. As a subgenre, the "inquiry into the metropolis" foregrounds the affinities between a mode of figural thought, like that provided by the essay, and a material reality, like the city with its plethora of symbolic configurations through which it is possible to examine social facts.

    2011-01-01

    High-throughput sequencing is now routinely performed in many experiments. But the analysis of the millions of sequences generated, is often beyond the expertise of the wet labs who have no personnel specializing in bioinformatics. Whereas several tools are now available to map high-throughput sequencing data on a genome, few of these can extract biological knowledge from the mapped reads. We have developed a toolbox called S-MART, which handles mapped RNA-Seq data. S-MART is an intuitive and lightweight tool which performs many of the tasks usually required for the analysis of mapped RNA-Seq reads. S-MART does not require any computer science background and thus can be used by all of the biologist community through a graphical interface. S-MART can run on any personal computer, yielding results within an hour even for Gb of data for most queries. S-MART may perform the entire analysis of the mapped reads, without any need for other ad hoc scripts. With this tool, biologists can easily perform most of the analyses on their computer for their RNA-Seq data, from the mapped data to the discovery of important loci. PMID:21998740

    Full Text Available An analysis of key genes and enzymes of the betacyanin biosynthetic pathway in Amaranthus hypochondriacus (Ah was performed. Complete cDNA sequence of Ah genes coding for cyclo-DOPA 5-O glucosyltransferase (AhcDOPA5-GT, two 4, 5-DOPA-extradiol-dioxygenase isoforms (AhDODA-1 and AhDODA-2, respectively, and a betanidin 5-O-glucosyltransferase (AhB5-GT, plus the partial sequence of an orthologue of the cytochrome P-450 R gene (CYP76AD1 were obtained. With the exception AhDODA-2, which had a closer phylogenetic relationship to DODA-like genes in anthocyanin-synthesizing plants, all genes analyzed closely resembled those reported in related Caryophyllales species. The measurement of basal gene expression levels, in addition to the DOPA oxidase tyrosinase (DOT activity, in different tissues of three Ah genotypes having contrasting pigmentation levels (green to red-purple was determined. Additional analyses were performed in Ah plants subjected to salt and drought stress and to two different insect herbivory regimes. Basal pigmentation accumulation in leaves, stems and roots of betacyanic plants correlated with higher expression levels of AhDODA-1 and AhB5-GT, whereas DOT activity levels coincided with pigment accumulation in stems and roots and with the acyanic nature of green plants, respectively, but not with pigmentation in leaves. Although the abiotic stress treatments tested produced changes in pigment levels in different tissues, pigment accumulation was the highest in leaves and stems of drought stressed betacyanic plants, respectively. However, tissue pigment accumulation in stressed Ah plants did not always correlate with betacyanin biosynthetic gene expression levels and/or DOT activity. This effect was tissue- and genotype-dependent, and further suggested that other unexamined factors were influencing pigment content in stressed Ah. The results obtained from the insect herbivory assays, particularly in acyanic plants, also support the

    A novel Cu/ZnSOD from Amaranthus hypochondriacus was cloned, expressed, and characterized. Nucleotide sequence analysis showed an open reading frame (ORF) of 456 bp, which was predicted to encode a 15.6-kDa molecular weight protein with a pI of 5.4. Structural analysis showed highly conserved amino acid residues involved in Cu/Zn binding. Recombinant amaranth superoxide dismutase (rAhSOD) displayed more than 50 % of catalytic activity after incubation at 100 °C for 30 min. In silico analysis of Amaranthus hypochondriacus SOD (AhSOD) amino acid sequence for globularity and disorder suggested that this protein is mainly disordered; this was confirmed by circular dichroism, which showed the lack of secondary structure. Intrinsic fluorescence studies showed that rAhSOD undergoes conformational changes in two steps by the presence of Cu/Zn, which indicates the presence of two binding sites displaying different affinities for metals ions. Our results show that AhSOD could be classified as an intrinsically disordered protein (IDP) that is folded when metals are bound and with high thermal stability. PMID:26129702

Martí resume una visión inicial de nuestra América en la figura lítica de Chacmool cuando después de ser expropiada por el gobierno yucateco, el Apóstol cubano la admira en la ciudad de Mérida y expresa que es la síntesis de las culturas americanas. Aspecto poco estudiado en la obra de Martí es este acercamiento etnográfico a la realidad maya de Yucatán y Guatemala.   This paper aims at presenting and examining the change of perception José Martí underwent in relation to the role of the native peoples of America between 1875 and 1878, the years he lived in Mexico and Guatemala, during which he spent a large amount of time in Yucatan, where he was able to get to know the Mayan culture and its people first hand. Martí summarized his initial vision of our America in the lithic figure of Chacmool, which he was able to admire in the city of Merida, after it had been expropriated by the government of Yucatan. The Cuban apostle described this as a synthesis of American cultures. This ethnographic insight into the Mayan reality in Yucatan and Guatemala represents a scarcely explored aspect of Martí's work.

    Full Text Available Abstract Background Translational research typically requires data abstracted from medical records as well as data collected specifically for research. Unfortunately, many data within electronic health records are represented as text that is not amenable to aggregation for analyses. We present a scalable open source SQL Server Integration Services package, called Regextractor, for including regular expression parsers into a classic extract, transform, and load workflow. We have used Regextractor to abstract discrete data from textual reports from a number of ‘machine generated’ sources. To validate this package, we created a pulmonary function test data mart and analyzed the quality of the data mart versus manual chart review. Methods Eleven variables from pulmonary function tests performed closest to the initial clinical evaluation date were studied for 100 randomly selected subjects with scleroderma. One research assistant manually reviewed, abstracted, and entered relevant data into a database. Correlation with data obtained from the automated pulmonary function test data mart within the Northwestern Medical Enterprise Data Warehouse was determined. Results There was a near perfect (99.5% agreement between results generated from the Regextractor package and those obtained via manual chart abstraction. The pulmonary function test data mart has been used subsequently to monitor disease progression of patients in the Northwestern Scleroderma Registry. In addition to the pulmonary function test example presented in this manuscript, the Regextractor package has been used to create cardiac catheterization and echocardiography data marts. The Regextractor package was released as open source software in October 2009 and has been downloaded 552 times as of 6/1/2012. Conclusions Collaboration between clinical researchers and biomedical informatics experts enabled the development and validation of a tool (Regextractor to parse, abstract and assemble

Sin embargo, Marte muestra numerosas formas de erosión y acumulación que evidencian la presencia de flujos de agua en superficie. La presencia de estas formas debidas al flujo de agua constituye para algunos investigadores la principal prueba de que Mar...

    High-throughput sequencing is now routinely performed in many experiments. But the analysis of the millions of sequences generated, is often beyond the expertise of the wet labs who have no personnel specializing in bioinformatics. Whereas several tools are now available to map high-throughput sequencing data on a genome, few of these can extract biological knowledge from the mapped reads. We have developed a toolbox called S-MART, which handles mapped RNA-Seq data. S-MART is an intuitive and...

    This paper estimates the effect of Wal-Mart expansion on retail employment at the county level. Using an instrumental-variables approach to correct for both measurement error in entry dates and endogeneity of the timing of entry, I find that Wal-Mart entry increases retail employment by 100 jobs in the year of entry. Half of this gain disappears over the next five years as other retail establishments exit and contract, leaving a long-run statistically significant net gain of 50 jobs. Wholesal...

  16. From Sarmiento to Martí and Hostos: Extricating the Nation from Coloniality

    Directory of Open Access Journals (Sweden)

    Thomas Ward

    2007-10-01

    Full Text Available The present article examines constructions of  race, nation and mestizaje in work of Domingo  Faustino Sarmiento, José Martí and Eugenio  Maria de Hostos. The first championed the prevailing nineteenth-century view that humanity  was being debilitated by a constant battle between  civilization and barbarism while the two Antilleans questioned it in their search for a society  liberated from coloniality. Martí denied the notion  of privilege based on Europeanness, proclaiming  that whites, blacks, indigenous and mixed-race  peoples could all claim equal rights under natural  law. Hostos agreed with Martí but took his recommendation one step further by proposing race  mixing, with all ethnic groups equally forming a  new society. Therefore Martí’s negation of racial  differences becomes with Hostos a quest for a  society that would eventually become homogeneous through miscegenation. The study concludes  that there is a timelessness inherent to Martí and  Hostos’s work that still speaks to us today in the  midst of a new awareness of ethnicity’s impact on  society. Resumen:De Sarmiento a Martí y Hostos: Rescatando al país de la colonialidadEl presente artículo examina las construcciones de  raza, nación y mestizaje en las obras de Domingo  Faustino Sarmiento, José Martí y Eugenio María de  Hostos. El primero defendía la construcción deci monónica de que la humanidad había sido debilitada por una constante batalla entre civilización y  barbarie mientras los dos antillanos la cuestionaban  en su búsqueda de una sociedad libre de la colonialidad. Martí niega la noción de privilegio basado en  lo europeo y proclama que los blancos, negros,  indígenas y personas de raza mezclada podrían  reclamar la igualdad de derechos bajo leyes naturales. Hostos estuvo de acuerdo con Martí pero llevó  su recomendación un paso más allá, proponiendo  que la mezcla de razas, con todos los grupos

    Full Text Available Abstract Background The aqueous-methanolic extract of Amaranthus spinosus (A. spinosus Linn., whole plant, was studied for its laxative, spasmolytic and bronchodilator activities to validate some of its medicinal uses. Methods The crude extract of A. spinosus was studied in-vivo for bronchodilator and laxative activities and in-vitro using isolated tissue preparations which were mounted in tissue baths assembly containing physiological salt solutions, maintained at 37°C and aerated with carbogen, to assess the spasmolytic effect and to find out the possible underlying mechanisms. Results In the in-vivo experiments in mice, the administration of A. spinosus increased fecal output at doses of 100 and 300 mg/kg showing laxative activity. It also inhibited carbachol-induced bronchospasm in anesthetized rats at 1, 3, 10 and 30 mg/kg indicative of bronchodilator activity. When tested on isolated gut preparations, the plant extract showed a concentration-dependent (0.01-10.0 mg/ml spasmogenic effect in spontaneously contracting rabbit jejunum and guinea-pig ileum. The spasmogenic effect was partially blocked in tissues pretreated with atropine (0.1 μM. When tested on K+ (80 mM-induced sustained contractions in isolated rabbit jejunum, the plant extract caused complete relaxation and also produced a shift in the Ca++ concentration-response curves (CRCs towards right, similar to diltiazem. In rabbit trachea, the plant extract completely inhibited K+ (80 mM and carbachol (CCh, 1 μM-induced contractions at 1 mg/ml but pretreatment of tissue with propranolol (1 μM, caused around 10 fold shift in the inhibitory CRCs of the plant extract constructed against CCh-induced contraction. The plant extract (up to 0.3 mg/ml also increased both force and rate of spontaneous contractions of isolated guinea-pig atria, followed by relaxation at higher concentration (1.0-5.0 mg/ml. The cardio-stimulant effect was abolished in the presence of propranolol, similar to

  18. Effects of Copper on the Photosynthesis and Oxidative Metabolism of Amaranthus tricolor Seedlings

    2007-01-01

    The objective of the present study was to gain better insight into the physiological mechanisms on the effects of copper (Cu) on photosynthesis and active oxygen metabolism in three-colored amaranth plant (Amaranthus tricolor). Three-colored amaranth seedlings were subjected to different Cu levels in soils during the entire experimental period. The parameters of growth, photosynthesis, mineral elements contents, and active oxygen metabolism were investigated using plant physiological methods. The results showed that 2.0 and 4.0 mmol Cu kg-1 treatments decreased the whole plant biomass to 91 and 73% of the control, respectively. The net photosynthetic rate (Pn) and the stomatal conductance (gs) were similarly reduced in the third leaves of three-colored amaranth seedlings treated with 2.0 and 4.0 mmol Cu kg-1 soil,respectively. None of the investigated Cu levels decreased the internal CO2 concentration (Ci). The effect of Cu on the potential efficiency of photosystem Ⅱ (Fv/Fm) was negligible, whereas the effect of Cu on the PS Ⅱ quantum efficiency (φPS Ⅱ) after plant adaptation in actinic irradiation was more noticeable. On the other hand, decreases in water percentage, contents of photosynthetic pigments and mineral elements including Fe, K, and Mg, and significant increase in the Cu content were observed in the third leaves of Cu-treated plants. Superoxide dismutase (SOD) and peroxidase (POD)activities as well as the proline (Pro) content significantly increased in the third leaves of the three-colored amaranth seedlings treated with 2.0 and 4.0 mmol Cu kg-1 soil, while catalase (CAT) and ascorbate peroxidase (APX) activities as well as the contents of carotenoid (Car), glutathione (GSH), and ascorbic acid (AsA) decreased, and accompanied by the increases in the contents of hydrogen preoxide(H2O2),superoxide anion(O-·2),and malondialdehyde(MDA),and electrolyte leakage. As a result of the imbalance of active oxygen metabolism, Pn and φPSⅡ decreased, and

All resources available through the portal are independently administered and funded by their host organizations. The BioMart data federation technology provides a unified interface to all the available data. The latest version of the portal comes with many new databases that have been created by our ever-growing community. It also comes with better support and extensibility for data analysis and visualization tools. A new addition to our toolbox, the enrichment analysis tool is now accessible through graphical and web service interface. The BioMart community portal averages over one million requests per day. Building on this level of service and the wealth of information that has become available, the BioMart Community Portal has introduced a new, more scalable and cheaper alternative to the large data stores maintained by specialized organizations.

  3. Concentrations of long-chain acyl-acyl carrier proteins during fatty acid synthesis by chloroplasts isolated from pea (Pisum sativum), safflower (Carthamus tinctoris), and amaranthus (Amaranthus lividus) leaves

    International Nuclear Information System (INIS)

    Fatty acid synthesis from [1-14C]acetate by chloroplasts isolated from peas and amaranthus was linear for at least 15 min, whereas incorporation of the tracer into long-chain acyl-acyl carrier protein (ACP) did not increase after 2-3 min. When reactions were transferred to the dark after 3-5 min, long-chain acyl-ACPs lost about 90% of their radioactivity and total fatty acids retained all of theirs. Half-lives of the long-chain acyl-ACPs were estimated to be 10-15 s. Concentrations of palmitoyl-, stearoyl-, and oleoyl-ACP as indicated by equilibrium labeling during steady-state fatty acid synthesis, ranged from 0.6-1.1, 0.2-0.7, and 0.4-1.6 microM, respectively, for peas and from 1.6-1.9, 1.3-2.6, and 0.6-1.4 microM, respectively, for amaranthus. These values are based on a chloroplast volume of 47 microliters/mg chlorophyll and varied according to the mode of the incubation. A slow increase in activity of the fatty acid synthetase in safflower chloroplasts resulted in long-chain acyl-ACPs continuing to incorporate labeled acetate for 10 min. Upon re-illumination following a dark break, however, both fatty acid synthetase activity and acyl-ACP concentrations increased very rapidly. Palmitoyl-ACP was present at concentrations up to 2.5 microM in safflower chloroplasts, whereas those of stearoyl- and oleoyl-ACPs were in the lower ranges measured for peas. Acyl-ACPs were routinely separated from extracts of chloroplasts that had been synthesising long-chain fatty acids from labeled acetate by a minor modification of the method of Mancha et al. The results compared favorably with those obtained using alternative analytical methods such as adsorption to filter paper and partition chromatography on silicic acid columns

  4. Etnocentrismo, racismo y miedo: los indígenas y los incultos en Martí

    Directory of Open Access Journals (Sweden)

    Jorge Camacho

    2010-04-01

    Full Text Available In the following article I return to the idea of ethnicity and liberalism in Latin America during the last part of the 19th century. I also discuss Martí’s view of the Indians after 1885, when his chronicles were fueled by the rhetoric of pro-indigenous groups such as the Friends of Indians Association. I propose to look at other ways in which Martí’s ethnocentric view of culture and race intertwined with his agenda of “defending” the Indians, especially in his essay “Nuestra América.” For that purpose I retrace some of my previous arguments and discuss other essays that have recently elaborated on Martí’s “other side”, the one that imposes on the Indians his own liberal agenda, and the vision of modernity that the elites were constructing in Latin America at the end of 19th century. In my previous articles I discussed Martí’s chronicles on the Guatemalan, Mexican and American Indians and here I will focus on the similarities between the positivists in Mexico and Martí’s emphasis on “scientific politics” as well as his fear that those that were at the lowest level of society could one day revolt against the republic and destroy the justice “accumulated in books.” For books symbolized for Martí the “lettered elite”, those that had power and exercised it to their own advantage. He talked about this fear in Mexico, and in his most famous essay he returned to it again with a somewhat different perspective, but still with the conviction that within a democracy everything could be solved and a revolt from the “unlettered” masses was not justified. I argue that even if “Nuestra América” meant a more positive view of the “Indian problem”, Martí still considers the Indians, the “gauchos” and the rest of the “incultos” as a threat. They were the natural ally of the “caudillos” that ruled for so long Latin America, charismatic caudillos such as Juan Manuel de Rosas.

  5. Ionizing radiation affects generation of MART-1-specific cytotoxic T cell responses by dendritic cells

    International Nuclear Information System (INIS)

    Full text: The human MART-1/Melan-A (MART-1) melanoma tumor antigen is known to be recognized by cytotoxic T lymphocytes (CTLs) and several groups are using this target for clinical immunotherapy. Most approaches use dendritic cells (DCs) that are potent antigen presentation cells for initiating CTL responses. In order for CTL recognition to occur, DCs must display 9-residue antigenic peptides on MHC class I molecules. These peptides are generated by proteasome degradation and then transported through the endoplasmic reticulum to the cell surface where they stabilize MHC class I expression. Our previous data showed that irradiation inhibits proteasome function and, therefore, we hypothesized that irradiation may inhibit antigen processing and CTL activation, as has been shown for proteasome inhibitors. To study the importance of irradiation effects on DCs, we studied the generation MART-1-specific CTL responses. Preliminary data showed that irradiation of murine bone marrow derived DCs did not affect expression of MHC class I, II, CD80, or CD86, as assessed by flow cytometric analyses 24-hour after irradiation. The effect of irradiation on MART-1 antigen processing by DCs was evaluated using DC transduced with adenovirus MART-1 (AdVMART1). C57BL/6 mice were immunized with AdVMART1 transduced DCs, with and without prior irradiation. IFN-γ production was measured by ELISPOT assays after 10-14 days of immunization. Prior radiation treatment resulted in a significant decrease in MART-1-specific T cell responses. The ability of irradiated and non-irradiated AdVMART1/DC vaccines to protect mice against growth of murine B16 tumors, which endogenously express murine MART-1, was also examined. AdVMART1/DC vaccination protected C57BL/6 mice against challenge with viable B16 melanoma cells while DCs irradiated (10 Gy) prior to AdVMART1 transduction abrogated protection. These results suggest that proteasome inhibition in DCs by irradiation may be a possible pathway in

    2007-06-01

    Full Text Available Forty seven of 150, 15-month-old long weaners died of an acute renal disease syndrome following introduction into an old maize field with a heavy stand of Amaranthus spp. The clinical syndrome was characterised by sudden onset neurological disease with ataxia and recumbency. Subcutaneous oedema, ascites and perirenal oedema with urine odour were the major gross necropsy findings. Renal histopathology revealed marked coagulative renal tubular necrosis of the proximal and distal straight tubules with intertubular haemorrhage. Acute renal failure and perirenal oedema has been described in cattle, pigs, horses and sheep associated with the ingestion of A. hybridus L. and A. retroflexus L. This perirenal oedema syndrome has been widely reported in the Americas, while in South Africa intoxication with the amaranths has only previously been associated with nitrate and possibly oxalate poisoning in cattle.

  7. Influence ofAmaranthus hybridus L. allelochemics on oviposition behavior ofSpodoptera exigua andS. eridania (Lepidoptera: Noctuidae).

    1985-05-01

    Common pigweed,Amaranthus hybridus L., is a favorite host of the beet army worm (BAW),Spodoptera exigua L. Chemicals extracted from homogenized pigweed with distilled water, ethanol, or dichloromethane and sprayed back on pigweed deterred oviposition by the BAW. Similarly, water extracts of frass from conspecific larvae or southern armyworm (SAW) larvae,S. eridania (Cramer), fed pigweed leaves and sprayed back on pigweed plants also deterred BAW oviposition, thus confirming that deterrence was due to plant allelochemics rather than specific compounds associated with the metabolic or excretory products of the larvae. Confirmation of the presence of oviposition-deterring chemicals in pigweed was used to explain a previously observed seasonal displacement of BAW by SAW on pigweed in the field. PMID:24310126

  8. Isolation of a choline monooxygenase cDNA clone from Amaranthus tricolor and its expressions under stress conditions

    2001-01-01

    Plants synthesize the osmoprotectant glycine betaine (GB) via choline→betaine aldehyde→glycine betaine[1]. Two enzymes are involved in the pathway, choline monooxygenase (CMO) and betaine aldehyde dehydrogenase (BADH). A full length CMO cDNA (1,643bp) was cloned from Amaranthus tricolor. The open reading frame encoded a 442-amino acid polypeptide, which showed 69% identity with CMOs in Spinacia oleracea L. And Beta vulgaris L. DNA gel blot analysis indicated the presence of one copy of CMO gene in the A. Tricolor genome. The expressions of CMO and BADH proteins in A.tricolor leaves significantly increased under salinization, drought and heat stress (42℃), as determined by immunoblot analysis, but did not respond to cold stress (4℃), or exogenous ABA application. The increase of GB content in leaves was parallel to CMO and BADH contents.

    Full Text Available Background: Ischuria is a health and social problem, having a negative impact on sufferers. This study therefore was a preliminary investigation of the ischuretic property and safety for use of a hydro-ethanolic extract of Amaranthus spinosus used traditionally in managing ischuria. Methods: Phytochemical screening, thin layer chromatography and high performance liquid chromatography were performed on the extract to establish fingerprints for identification. Acetylcholine, Nicotine, and the extract were applied to an isolated rat urinary bladder to ascertain contractile response. The possible receptor site(s of action was also investigated using isolated rabbit jejunum, and guinea-pig ileum preparations. In-house observation, hematological analysis, and liver and kidney function tests were performed on Sprague-Dawley rats, in acute and sub-acute toxicity studies. Results: The extract had contractile effects on the rat urinary bladder (similar to acetylcholine and nicotine and rabbit jejunum. Its contractile effect of the guinea-pig ileum was significantly inhibited by hexamethonium (77.50 ± 8.50 %; P ≤ 0.001 and to a lesser extent by mepyramine (49.2 ± 6.80 %; P ≤ 0.001 and Atropine (22.45 ± 5.22 %; P ≤ 0.01. The extract (80-800 mg kg-1 was not lethal and a 160 and 240 mg kg-1 dose had no adverse effect on blood, liver, kidney metabolic function. Conclusions: The hydro-ethanolic extract of Amaranthus spinosus has ischuretic activity possibly mediated via nicotinic, histaminic and muscarinic receptor stimulation and is safety to use in ischuria.

  10. Control of photosynthesis by the carbohydrate level in leaves of the C4 plant Amaranthus edulis L.

    1989-04-01

    Photosynthesis was studied in relation to the carbohydrate status in intact leaves of the C4 plant Amaranthus edulis. The rate of leaf net CO2 assimilation, stomatal conductance and intercellular partial pressure of CO2 remained constant or showed little decline towards the end of an 8-h period of illumination in ambient air (340 μbar CO2, 21% O2). When sucrose export from the leaf was inhibited by applying a 4-h cold-block treatment (1°C) to the petiole, the rate of photosynthesis rapidly decreased with time. After the removal of the cold block from the petiole, further reduction in photosynthetic rate occurred, and there was no recovery in the subsequent light period. Although stomatal conductance declined with time, intercellular CO2 partial pressure remained relatively constant, indicating that the inhibition of photosynthesis was not primarily caused by changes in stomatal aperture. Analysis of the leaf carbohydrate status showed a five- to sixfold increase in the soluble sugar fraction (mainly sucrose) in comparison with the untreated controls, whereas the starch content was the same. Leaf osmotic potential increased significantly with the accumulation of soluble sugars upon petiole chilling, and leaf water potential became slightly more negative. After 14 h recovery in the dark, photosynthesis returned to its initial maximum value within 1 h of illumination, and this was associated with a decline in leaf carbohydrate levels overnight. These data show that, in Amaranthus edulis, depression in photosynthesis when translocation is impaired is closely related to the accumulation of soluble sugars (sucrose) in source leaves, indicating feedback control of C4 photosynthesis. Possible mechanisms by which sucrose accumulation in the leaf may affect the rate of photosynthesis are discussed with regard to the leaf anatomy of C4 plants. PMID:24212494

    2005-01-01

    A metabolite, which had an inhibitory effect on plant growth, was isolated from cultural filtrate of Botrytis cinerea isolate BC4 by column chromatography on silica gel and preparative HPLC. Its structure was determined from HPLC-ESI MS, GC,IR, 1H NMR and 13C NMR spectral data, as well as chemical hydrolysis. The results showed that this metabolite was quite similar to abscisic acid-β-D-glucopyranosyl ester(ABAGE) in structure. The inhibitory effect of the ABAGE-like metabolite on plant growth was investigated using a weed Amaranthus retroflexus L. as a bioassay material. The results showed that it inhibited hypocotyls and roots growth of A. retroflexus (Amaranthus retroflexus L.) seedlings when its concentration was over 0.5 μM. The concentrations for 50% inhibition of hypocotyls and roots growth of A. retroflexus seedlings were 2.8 and 1.4 μM, respectively.

    Even with multidisciplinary treatment, the prognosis and quality of life of patients diagnosed with head and neck squamous cell carcinoma (HNSCC) are still not satisfactory. Previously, 19-Nor-2α-(3-hydroxypropyl)-1α,25(OH)2D3 (MART-10), the new brand 1α,25(OH)2D3 analog, has been demonstrated to be an effective drug to inhibit HNSCC growth in vitro. Since most cancer patients die of metastasis, in this study, the antimetastatic effect of MART-10 on HNSCC was investigated. Our results reveal that both 1α,25(OH)2D3 and MART-10 effectively repressed the migration and invasion of HNSCC cells, with MART-10 being much more potent than 1α,25(OH)2D3. The antimetastatic effect of 1α,25(OH)2D3 and MART-10 was mediated by attenuation of epithelial–mesenchymal transition (EMT), which was supported by the finding that the expression of EMT-inducing transcriptional factors, Sail and Twist, was inhibited by 1α,25(OH)2D3 and MART-10. The upregulation of E-cadherin and downregulation of N-cadherin in FaDu cells induced by both drugs further confirmed the repression of EMT. In addition, 1α,25(OH)2D3 and MART-10 treatment inhibited intracellular MMP-9 expression and extracellular MMP activity in FaDu cells. Collectively, our results suggest that the less-calcemia 1α,25(OH)2D3 analog, MART-10, is a promising drug for HNSCC treatment. Further clinical studies are warranted.

    Full Text Available José Martí llegó a España el 1 de febrero de 1871 como consecuencia de la deportación de la que fuera objeto por las autoridades cubanas quienes, desde 1869, lo habían retenido en prisión a causa de su postura contraria a la Metrópoli española. Su estadía en Madrid le sirvió para abrirse espacio en el mundo intelectual, sobre todo tras la publicación del artículo “Castillo” y del ensayo “El Presidio Político en Cuba”. La estancia de Martí en España le sirvió para culminar sus estudios, insertarse sobre debates de enorme significación filosófica, así como en la Masonería. Martí partió de la Península Ibérica, de retorno a América a finales de noviembre de 1874 en dirección a México. Había experimentado un destierro purificador que solo pudo ser posible en una persona del talento como fue el caso del cubano José Martí.   José Marti arrived in Spain on February 1, 1871, as a result of the deportation that was imposed on him by Cuban authorities, which since 1869 had kept him in prison due to his attitude against the Spanish Metropolis. During his stay in Madrid, he conquered new spaces in the intellectual world, especially after the publication of the article “Castillo” (“Castle” and the essay "El Presidio Político en Cuba" (“Political Imprisonment in Cuba”. While in Spain, Martí managed to complete his studies, engage in debates of great philosophical significance, as well as with the Masonry. In late November 1874, Martí left the Iberian Peninsula and returned to America, arriving in Mexico. Therefore, he experienced a purifying exile that could only be possible for a talented person like him.

This poetry has been regarded by critics as linked to historical realism, and in our opinión consitutes the literary consolidation of the Roda de Ter-born poet after his his apprenticeship in existential poetry. Throughout five books and a long poem, the authorembodies a double social dimensión in his verse: on the one hand, extemal and collective history, especially achieved through the universe of the village and the factory; on the other hand, the inner and personal history dealing with aspects of his most intérnate experience in themes such as love or the function of poetry.  Paraules clau: Miquel Martí i Pol; poesia existencial; poesia catalana contemporània

    The characterization of amaranth seeds (Amaranthus spp.) was developed for Amaranthus hypochondriacus, Amaranthus cruentus, and Amaranthus dubius. The elemental concentrations were determined by inductively coupled plasma optic atomic spectroscopy. Pattern recognition methods were used for the characterization of seed samples: nonsupervised methods included principal components analysis and cluster analysis; supervised methods were linear discriminant analysis and partial least squares discriminant analysis (PLS-DA). Informed are the concentrations of the following elements: Ag, Al, Ba, Ca, Co, Cr, Cu, Fe, K, La, Li, Mg, Mn, Mo, Na, Ni, P, S, Sr, V, Zn, and Zr. The lowest mineral content was found in A. hypochondriacus, and the highest one was found in A. dubius. For the classification, selected variables for all multivariate methods were Ba, Cr, Li, Mn, Ni, S, and Sr. Nonsupervised methods allowed us to distinguish between the three species of amaranth; however, PLS-DA supervised methods showed the best prediction ability.

Con él llegaron a las Islas los novedosos planteamientos de la escuela hispalense de imaginería y también los modos de trabajo que regían sus obradores, que pudo trasmitir a aprendices locales en Garachico. La localización en las escribanías tinerfeñas de un documento inédito nos permite respaldar su autoría respecto a la desaparecida imagen de la Virgen de los Afligidos, que realizó junto al Nazareno para la Orden Tercera del Convento franciscano de Los Realejos en 1637.The architect and sculptor Martín de Andújar Cantos moved from Seville, where he had worked under the guidance of Juan Martínez Montañés, to the Canary Islands, where he lived from 1634 to 1641. Novel proposals from the Seville School of religious imagery arrived with him at the islands, as well as the new working methods employed at his workshopds, which he was able to transmit to the Garachico local apprentices. The finding at the Island’s Court Clerkships of an unpublished document allows us to back his authorship of the dissapeared image of the Virgen de los Afligidos, made next to the Nazarene in 1637 by commission of the Third Order of Los Realejos franciscan convent.

    Full Text Available The growing need for huge volume of data in enterprise and corporate environment, fuel the demand of data warehousing. Data warehousing collects the data at different levels (i.e., departmental, operational, functional and stored as a collective data repository with better storage efficiency. Various data warehousing models concentrate on storing the data more efficiently and quickly. In addition accessibility of data from the warehouse needs better understanding of the structure in which the data layers are stored in the repository. However function requirements of users are not easily understood by the data warehouse model. It needs efficient decision support system to extract the required user demanded data from data warehouse. To handle the issue of functional decision support system to extract user relevant data, data marts are introduced. Data marts built separate functional data repository layers based on the departmental decision support requirements in the enterprise and corporate data applications. In our research work, we plan to built a Functional Layer Interfaced Data Mart Architecture (FLIDMA to provide a better decision support system for larger corporate and enterprise data applications. In this work, the functional behavior of the corporate system is analyzed, based on its operational goal to build layers of data storage repositories with relevant data attributes using functional behavior pattern (FBP. An experimental evaluation is conducted with benchmark datasets from UCI repository data sets and compared with existing multi-functional data warehousing model in terms of number of functional data attributes, attribute relativity, analysis of functional behavior.

  7. MARTe framework; a middle-ware for real-time applications development

    International Nuclear Information System (INIS)

    The Multi-threaded Application Real-Time executor (MARTe) is a C++ framework that provides a development environment for the design and deployment of real-time applications, e.g. control systems. The kernel of MARTe comprises a set of data-driven independent blocks, connected using a shared bus. This modular design enforces a clear boundary between algorithms, hardware interaction and system configuration. The architecture, being multi-platform, facilitates the test and commissioning of new systems, enabling the execution of plant models in offline environments and with the hardware-in-the-loop, whilst also providing a set of non-intrusive introspection and logging facilities. Furthermore, applications can be developed in non real-time environments and deployed in a real-time operating system, using exactly the same code and configuration data. The framework is already being used in several fusion experiments, with control cycles ranging from 50 microseconds to 10 milliseconds exhibiting jitters of less than 2%, using VxWorksR, RTAI or Linux. Codes can also be developed and executed in Microsoft WindowsR and SolarisR. This paper discusses the main design concepts of MARTe, in particular the architectural choices which enabled the combination of real-time accuracy, performance and robustness with complex and modular data driven applications.

    Full Text Available Semblanza del escritor y político cubano José Martí (1853-1895, con especial atención a la vigencia de su pensamiento ético, base de su permanente actualidad. Martí fue el organizador y líder de la última guerra americana contra el colonialismo europeo clásico, pero el sentido profundo que dio a esa lucha la convirtió en una verdadera guerra de liberación nacional: el primer movimiento concreto contra el imperialismo. Entre los rasgos más originales del pensamiento martiano están: la proclamación de la igualdad de razas; la búsqueda de la superación de las diferencias de clase mediante el equilibrio de las fuerzas sociales; la reivindicación de la solidaridad hacia los humildes como un deber; la predicación de una “guerra sin odios”, que debía ser obra del pueblo y no de líderes; la comprensión y definición de Nuestra América; la insistencia en la necesidad de una descolonización cultural latinoamericana; y el antiimperialismo.   This paper is a sketch of the Cuban writer and politician José Martí (1853-1895, with special attention to the validity of his ethical thinking, which is the basis of his permanent relevance. Martí was the organizer and leader of the last American war against European colonialism, but the deep commitment he made to that struggle turned it into a war of national liberation, the first concrete movement against imperialism. Among the most original features of Martí’s thought are the proclamation of the equality of races; the search for overcoming class differences through the balance of social forces; solidarity with the poor being considered a duty; the preaching of a “war without hates” that must be the work of the people, its leaders; the comprehension and definition of Our America; the insistence on the need, throughout Latin America, of cultural decolonization; and an anti-imperialistic stance.

    Nuclear factor-Y (NF-Y), is a plant heterotrimeric transcription factor constituted by NF-YA, NF-YB and NF-YC subunits. The function of many NF-Y subunits, mostly of the A and B type, has been studied in plants, but knowledge regarding the C subunit remains fragmentary. Here, a water stress-induced NF-YC gene from Amaranthus hypochondriacus (AhNF-YC) was further characterized by its overexpression in transgenic Arabidospis thaliana plants. A role in development was inferred from modified growth rates in root, rosettes and inflorescences recorded in AhNF-YC overexpressing Arabidopsis plants, in addition to a delayed onset of flowering. Also, the overexpression of AhNF-YC caused increased seedling sensitivity to abscisic acid (ABA), and influenced the expression of several genes involved in secondary metabolism, development and ABA-related responses. An altered expression of the latter in water stressed and recovered transgenic plants, together with the observed increase in ABA sensitivity, suggested that their increased water stress resistance was partly ABA-dependent. An untargeted metabolomic analysis also revealed an altered metabolite pattern, both in normal and water stress/recovery conditions. These results suggest that AhNF-YC may play an important regulatory role in both development and stress, and represents a candidate gene for the engineering of abiotic stress resistance in commercial crops.

    The biochemical processes underlying variations of tolerance are often accompanied by source-sink transitions affecting carbon (C) metabolism. We investigated the tolerance of Amaranthus cruentus L. to total mechanical defoliation through development and in different growing seasons. Defoliated A. cruentus recovered ∼80% of their above-ground biomass and ∼100% of grain yield compared to intact plants if defoliation occurred early during ontogeny, but could not compensate when defoliation occurred during flowering. Tolerance index was higher in the summer season (-0.3) than in the winter season (-0.7). Overall, defoliation tolerance was closely related to phosphoenolpyruvate carboxylase (PEPC) activity in leaves and the subsequent accumulation of starch (∼500 μmol/gDW) and sucrose (∼140 μmol/gDW) in stems and roots. Thus, A. cruentus accumulated sufficient C in roots and stem to allow branching and shoot re-growth after defoliation, but it only possessed sufficient C reserves to maintain <19% seed yield in the absence of new vegetative tissue. Seed size was larger during the warm season but it was not affected by foliar damage. Seed chemical composition was altered by defoliation at flowering. We conclude that A. cruentus defoliation tolerance depends on both, the re-allocation of starch from stem and roots, and the activation of dormant meristems before flowering to generate new photosynthetic capacity to sustain seed filling.

    To investigate the possible function of the agglutinin from Amaranthus caudatus L. (ACA) in plant defending against insect pests, ACA cDNA was cloned by RT-PCR and the 5' and 3' sequences were confirmed by rapid amplification of cDNA ends (RACE). The phloem-specific expression vector of ACA gene, pBCACAc, was constructed based on the plant binary vector pBC438 and transfered into tobacco plants via Agrobacterium-mediated transformation method. Results from PCR and Southern blotting analysis showed that AOA gene was integrated into the genomes of transformed plants and the transgene integration varied from one to four estimated copies per genome. Western blotting analysis indicated that ACA gene was transcribed and translated in the transgenic plants. The bioassay of Myzus persicae Sulzer on detached leaves demonstrated that the 78% transgenic tobacco plants displayed an average aphid-resistant rate of more than 75%. Some apterous progeny of M. persicae were found dead on the resistant plants. These results indicate that ACA gene should be an effective aphid-resistant gene and could be valuable for application in crop breeding for aphid resistance.

    In a greenhouse pot experiment, we assessed the phytoextraction potential for Cd of three amaranth cultivars (Amaranthus hypochondriacus L. Cvs. K112, R104, and K472) and the effect of application of N, NP, and NPK fertilizer on Cd uptake of the three cultivars from soil contaminated with 5 mg kg(-1) Cd. All three amaranth cultivars had high levels of Cd concentration in their tissues, which ranged from 95.1 to 179.1 mg kg(-1) in leaves, 58.9 to 95.4 mg kg(-1) in stems, and 62.4 to 107.2 mg kg(-1) in roots, resulting in average bioaccumulation factors ranging from 17.7 to 29.7. Application of N, NP, or NPK fertilizers usually increased Cd content in leaves but decreased Cd content in stem and root. Fertilizers of N or NP combined did not substantially increase dry biomass of the 3 cultivars, leading to a limited increment of Cd accumulation. NPK fertilizer greatly increased dry biomass, by a factor of 2.7-3.8, resulting in a large increment of Cd accumulation. Amaranth cultivars (K112, R104, and K472) have great potential in phytoextraction of Cd contaminated soil. They have the merits of high Cd content in tissues, high biomass, easy cultivation and little effect on Cd uptake by fertilization. PMID:22567702

    Full Text Available Allelopathy is one of the important interactions among plants. Weeds can reduce crops productions in farms by their allelopathic effects. Redroot pigweed (Amaranthus retroflexus L. is the most common weed in Iran with well-known allelopathic potential. In the presented experiment, the allelopathic effects of redroot pigweed on germination and growth of four important crop species including cucumber (Cucumis sativus L., alfalfa (Medicago sativa L., common bean (Phaseulus vulgaris L. and bread wheat (Triticum aestivum L. was studied. The effect of different concentrations of redroot pigweed leachate on seed germination and seedlings growth parameters of tested plants was significant, but not same in all studied species. Bread wheat and cucumber were more resistance in seed germination stage in comparison to common bean and alfalfa. Except alfalfa, all plant species showed certain rate of resistance in the most measured parameters. According to the obtained results, bread wheat and common bean were the most resistant species, cucumber was resistant at low concentration but sensitive at high concentration, and alfalfa was the most sensitive species to the redroot pigweed leachate treatments. Therefore, the cultivation of resistant plant species (such as bread wheat and common bean plants in the regions with redroot pigweed’s invasion is appropriate way in management of the farms.

  16. Comparative analysis of EPICS IOC and MARTe for the development of a hard real-time control application

    International Nuclear Information System (INIS)

    EPICS is used worldwide to build distributed control systems for scientific experiments. The EPICS software suite is based around the Channel Access (CA) network protocol that allows the communication of different EPICS clients and servers in a distributed architecture. Servers are called Input/Output Controllers (IOCs) and perform real-world I/O or local control tasks. EPICS IOCs were originally designed for VxWorks to meet the demanding realtime requirements of control algorithms and have lately been ported to different operating systems. The MARTe framework has recently been adopted to develop an increasing number of hard real-time systems in different fusion experiments. MARTe is a software library that allows the rapid and modular development of stand alone hard real-time control applications on different operating systems. MARTe has been created to be portable and during the last years it has evolved to follow the multi-core evolution. In this paper we review several implementation differences between EPICS IOC and MARTe. We dissect their internal data structures and synchronization mechanisms to understand what happens behind the scenes. Differences in the component based approach and in the concurrent model of computation in EPICS IOC and MARTe are explained. Such differences lead to distinct time models in the computational blocks and distinct real-time capabilities of the two frameworks that a developer must be aware of. (authors)

    Maytenus ilicifolia Mart. ex Reiss. Maytenus ilicifolia (Celastraceae) is a native plant of South America and popularly known as 'espinheira-santa'. The aim of this study was to evaluate the antioxidant capacity of extracts and isolated compounds from this plant. The antioxidant activity of the crude and semipurified extracts and isolated compounds was evaluated through DPPH-radical and phosphomolybdenum-complex assays. By both methods, the ethyl-acetate fraction demonstrated better antioxidant capacity compared with vitamin C and trolox. In the compounds, the higher the number of hydroxyls, the greater the antioxidant activity. In addition, stereochemistry influenced antioxidant activity, i.e., compounds with 2 R,3 R showed greater activity than those with 2 R,3 S. (author)

    Full Text Available O grão de amaranto é geralmente consumido na sua forma integral. Este estudo teve como objetivo avaliar o efeito da moagem do grão de amaranto (Amaranthus cruentus brasileiro na composição química, nutricional, a estabilidade à oxidação e cor da farinha. Os grãos foram pré-condicionados para umidades entre 9,2 e 13,7% e fracionados em moinho para cereais. O aumento da umidade de 9,2 para 13,7% resultou na diminuição progressiva do rendimento da farinha, de 39 para 14%. A farinha refinada (quebra + redução, com 9,2% de umidade, mostrou teores de proteína total de 13,9%, contra 16,2% da farinha integral. O teor de lipídeos totais no amaranto integral (9,2% de umidade variou de 6,78, para 6,11% na farinha refinada e o teor de fibra nos farelos diminuiu de 3,6 para 3,1%, ao passo que a cor da farinha se tornou mais atraente. Conclui-se que o fracionamento da farinha do grão de amaranto, apesar de produzir uma farinha com melhor aparência e alto teor protéico, apresenta rendimento baixo e não mostra diminuição substancial no teor de óleo da farinha refinada como para garantir uma maior estabilidade à autooxidação.Grain amaranth is normally consumed whole.

  7. Prevalence and molecular identification of the sinus worm Skrjabingylus petrowi (Nematoda: Metastrongyloidea) from Martes spp. in Germany.

    The nematodes of the genus Skrjabingylus (family Metastrongylidae) can parasitise the nasal and frontal sinus cavities of different carnivore species. Until recently, Skrjabingylus petrowi Bageanov & Petrov, 1941, has mainly been described in pine martens (Martes martes Linnaeus, 1758) and sables (Martes zibellina Linnaeus, 1758) sampled in the European part of the former Soviet Union. Newer finds in the stone marten (Martes foina Erxleben, 1777) and from different parts of Europe suggest, however, that the species might have a broader host-species range than previously assumed and be geographically more widespread as well. Since most S. petrowi records have resulted from chance discoveries rather than systematic surveys, very little is known about the prevalence of S. petrowi in marten populations. Here, we report results of a 20-year extensive survey of fresh marten skulls, where we tested 1.059 marten carcasses originating from 248 localities in Germany for the presence of S. petrowi. We identified an infestation in only four M. martes individuals and one M. foina, despite using a reliable identification method. Based on the spicule lengths of the male nematodes, the parasites were identified as S. petrowi and genetic barcoding confirmed the identification of the samples. In a phylogenetic analysis, S. petrowi and Skrjabingylus nasicola (Leuckart, 1842), formed a sister clade to all the other members of the family Metastrongylidae. The low prevalence of S. petrowi is possibly due to its parasitising in the two marten species that are either not very common (M. martes) or predominantly live in urban habitat (M. foina).

    Grain amaranth (Amaranthus hypochondriacus L.) is abundant in oxalate and can secrete oxalate under aluminium (Al) stress. However, the features of Al-induced secretion of organic acid anions (OA) and potential genes responsible for OA secretion are poorly understood. Here, Al-induced OA secretion in grain amaranth roots was characterized by ion charomatography and enzymology methods, and suppression subtractive hybridization (SSH) together with quantitative real-time PCR (qRT-PCR) was used to identify up-regulated genes that are potentially involved in OA secretion. The results showed that grain amaranth roots secrete both oxalate and citrate in response to Al stress. The secretion pattern, however, differs between oxalate and citrate. Neither lanthanum chloride (La) nor cadmium chloride (Cd) induced OA secretion. A total of 84 genes were identified as up-regulated by Al, in which six genes were considered as being potentially involved in OA secretion. The expression pattern of a gene belonging to multidrug and toxic compound extrusion (MATE) family, AhMATE1, was in close agreement with that of citrate secretion. The expression of a gene encoding tonoplast dicarboxylate transporter and four genes encoding ATP-binding cassette transporters was differentially regulated by Al stress, but the expression pattern was not correlated well with that of oxalate secretion. Our results not only reveal the secretion pattern of oxalate and citrate from grain amaranth roots under Al stress, but also provide some genetic information that will be useful for further characterization of genes involved in Al toxicity and tolerance mechanisms.

    Amaranthus plants, or spinach, are used extensively as a vegetable and are known to possess medicinal properties. Neuroinflammation and oxidative stress play a major role in the pathogenesis of many neurodegenerative diseases, such as Alzheimer's disease and Parkinson's disease. Advanced glycation end-products (AGEs) cause cell toxicity in the human neuronal cell line, SH-SY5Y, through an increase in oxidative stress, as shown by reducing cell viability and increasing cell toxicity in a dose-dependent manner. We found that preincubation of SH-SY5Y cells with either petroleum ether, dichloromethane or methanol extracts of A. lividus and A. tricolor dose-dependently attenuated the neuron toxicity caused by AGEs treatment. Moreover, the results showed that A. lividus and A. tricolor extracts significantly downregulated the gene expression of the pro-inflammatory cytokines, TNF-α, IL-1 and IL-6 genes in AGEs-induced cells. We concluded that A. lividus and A. tricolor extracts not only have a neuroprotective effect against AGEs toxicity, but also have anti-inflammatory activity by reducing pro-inflammatory cytokine gene expression. This suggests that Amaranthus may be useful for treating chronic inflammation associated with neurodegenerative disorders. PMID:26393562

    Full Text Available Creada en 1962 por Sam Walton, una pequeña empresa de distribución norteamericana se convertirá rápidamente en la primera empresa mundial. Desde Bentonville, Arkansas, hasta el interior de China, Wal-Mart muestra un camino bastante clásico que va desde la sede principal de la empresa hacia una proliferación de sus tiendas en una quincena de países. Con una facturación de 405 mil millones de dólares en 2008, la empresa de distribución número uno en el mundo fue sobrepasada en abril de 2009 por la empresa petrolera Exxon Mobil en la clasificación de las quinientas empresas mundiales más importantes. Pero a diferencia de otras grandes transnacionales como Exxon Mobil o Microsoft, Wal-Mart, la primera empresa mundial de distribución, tiene que adaptarse al medio ambiente local con el fin de atraer a un máximo de consumidores. El artículo propone una aproximación a escala múltiple de las estrategias de desarrollo de esta firma internacional. Así, la aplicación de un análisis espacial es apropiada para esclarecer los vínculos existentes entre los territorios y las estrategias de los actores a diferentes escalas geográficas.

  14. An analysis of natural ventilation techniques to achieve indoor comfort in Wal-Mart express

    O'Dea, Shona

    Despite global efforts to reduce world fossil fuel dependency the world still obtains 81% of its energy from fossil fuels (IEA,2009). Modern renewable alternatives have been around since the mid twentieth century these alternatives have not been integrated into electrical grid systems at the exponential rate required to eradicate fossil fuels dependency. The problem, world energy demand, is too large to be satisfied by anything other than the energy-dense fossil fuels used today. We must change our energy intensive processes in order to conserve energy and hence reduce the demands that alternatives must satisfy. This research aims to identify sustainable design opportunities through the application of innovative technologies for the largest retailer in the US with the view that a viable conservative design measure could be applied to the store model, which is replicated across the country, causing a cumulative and hence larger impact on the company energy consumption as a whole. This paper will present the literature available on the 'big box' industry and Wal-Mart, comfort, natural ventilation and building simulation software and then perform an analysis into the viability of naturally ventilating the Wal-Mart Express sales zone using Monodraught natural ventilation windcatcher products

    Full Text Available Beyond historical and social implications, migration represents the possibility of crossing a threshold and opening oneself up to new empirical and emotional spaces. Amparo, the main character of Carmen Martín Gaite’s Irse de casa (1998, is the perfect personification of the gaitian feminine canon. After leaving Spain and settling in New York, she became a successful fashion designer, and seemed happy and easy-going. The bond with memory and the past is the main topic of this novel, as it is in most of Martín Gaite’s production. The window on the past that Amparo closed moving to the US suddenly reappears when she needs to discover herself and her origins. This inconvenience in an anonymous life brings huge changes that will condition her and her loved ones. Travelling to Spain and interacting with places and people connected with her childhood, Amparo goes through the window she had closed forty years before, restoring the order. The window connects the present and the past, symbolizes the emigrant’s transience, personified in the novel by Amparo, who can definitely find the lost serenity and heart’s-ease.

    2011-01-01

    Expression microarrays are commonly used to study transcriptomes. Most of the arrays are now based on oligo-nucleotide probes. Probe design being a tedious task, it often takes place once at the beginning of the project. The oligo set is then used for several years. During this time period, the knowledge gathered by the community on the genome and the transcriptome increases and gets more precise. Therefore re-annotating the set is essential to supply the biologists with up-to-date annotations. SigReannot-mart is a query environment populated with regularly updated annotations for different oligo sets. It stores the results of the SigReannot pipeline that has mainly been used on farm and aquaculture species. It permits easy extraction in different formats using filters. It is used to compare probe sets on different criteria, to choose the set for a given experiment to mix probe sets in order to create a new one.

    The aim of this study was to evaluate the chemical profile and antioxidant, antimicrobial and antiparasitic activities of the hydroalcoholic extract of the leaves of Ziziphus joazeiro Mart. (HELZJ). The antioxidant DPPH and FRAP assays and chemical profile were determined by colorimetric methods and HPLC/DAD. The antiparasitic, antibiotic and antibiotic-modifying activity were evaluated by microdilution assays. The HPLC-DAD assay showed the presence of mostly tannins and flavonoids, such as caffeic acid and quercetin. The levels of polyphenols and flavonoids were 183.136 mg/g extract and 7.37 mg/g extract, respectively. DPPH and FRAP showed low antioxidant activity for the extract. The antibacterial and antifungal activities were not of clinical relevance, showing MIC>1024 μg/mL. However, synergism was observed between HELZJ and the antibiotics amikacin and gentamicin, which resulted in decreased bacterial drug resistance. EHFZJ showed low toxicity in fibroblasts in vitro, while antiparasitic results against Trypnosoma cruzi, Leishmania braziliensis and Leishmania infantum were not clinically relevant. Thus, our results indicate that Z. joazeiro Mart. (HELZJ) could be a source of plant-derived natural products that could lead to the development of promising new antibiotic compounds for infectious diseases. PMID:25976809

  2. Literatura y filosofía: Sartre, Martín-Santos y Bartleby

    2006-04-01

    Full Text Available Luis Martín Santos has been, after his soon death, one of the most unfairly forgotten Spanish intellectuals. This situation happens to be even more unjust considering the success of his novel “Time of Silence” and his unfinished “Time of Destruction”. The works of this psychiatrist, philosophically formed in the existentialism tradition, tackle from psychiatric and medical studies to interpretations of Dilthey, Jaspers and Heidegger. Maybe the most important achievement made by Dr. Martín-Santos was the fact of pooling in his novels all the different fields he worked in, namely: existential philosophy, psychiatry and literature. This mutual influence leads to a clearly existential interpretation of the narrative subject and to a nihilist conception of freedom: the nothingness completely understood as Sartre did. And, consequently, the attractiveness of approaching the Spanish author through literary theories that are close to the French contemporary philosophy and the primacy, not only of the existential analysis in literature, but also of the influence of the literary character as a fiction that is able to create possible realities. That is why it is interesting to study “Bartleby the Scrivener” as a paradoxical example of the existential nothingness made flesh. To put it in a nutshell, the existential triviality, a sign of modern times, has been indeed very successfully portrayed by Martín-Santos.Luis Martín-Santos ha sido, tras su temprana muerte, uno de los grandes olvidados entre los intelectuales españoles del franquismo. Olvido especialmente injusto, teniendo en cuenta el éxito de su novela Tiempo de Silencio y su interesante proyecto inacabado Tiempo de Destrucción.

Two edible amaranthus herbs had high levels of Cd concentration in their tissues, ranging from 124. 1 to 225.9 mg/kg in leaves, from 56.2 to 87.6 mg/kg in stems, and from 57. 1 to 100. 6 mg/kg in roots, resulting in average Bioaccumulation Factors (BCF) ranging from 22. 4 to 40. 2. Application of N, NP or NPK fertilizers had significantly influenced Cd content in leaves, stems and roots. Fertilizers of NPK fertilizer greatly increased dry biomass, by a factor of 3. 5 for red amaranth or 3. 2 for green amaranth, resulting in a large increment of Cd uptake per plant. Two edible amaranthus herbs have great potential in phytoremediation of Cd contaminated soil. They have the merits of high Cd content in tissues, high biomass, easy cultivation, and little effect on Cd uptake by

    Full Text Available Este artículo es un acercamiento al difícil y singular diálogo con el pensamiento moderno y sus procedimientos del escritor, pensador y político cubano José Martí. La tesis es que el ideario de Martí expresó los intereses y la perspectiva de los pueblos de Hispanoamérica, a la que llamó Nuestra América, por oposición, según escribió “a la otra América, que no es nuestra”. Plenamente consciente de que la identidad de la región se sustentaba en una cultura nueva, mestiza de lo aborigen y lo español, el cubano dedicó su ensayo “Nuestra América” a explicar los factores internos que mantenían las estructuras sociales, políticas y de pensamiento de la época colonial, así como el peligro que representaba el creciente poderío de Estados Unidos.   This article aims to approach Cuban writer, thinker and politician José Martí's harsh, singular dialogue with modern thinking and its procedures. It argues that Martí's set of ideas expressed the interests and viewpoint of the peoples of Hispanic America, which he called Our America, as opposed to, according to his own texts, "the other America, the one that is not ours". Fully conscious of the fact that the region's identity was based on a new culture, resulting from a mix of the indigenous and the Spanish, Martí used his essay "Our America" (originally, "Nuestra América" to explain the internal factors that maintained the colonial social, political and ideological structures, in addition to expressing the threat the growing power of the United States represented.

    Full Text Available The aim of this study was to determine the possibility of amaranth cultivation in Central Italy and to determine the optimum plant density. Field trials were carried out in 2011 and 2012 under non-irrigated conditions in Tuscany (43° 18’ N, 11° 47’ E. Twelve accessions of two amaranth species (Amaranthus cruentus L. and A. hypochondriacus L. were utilised. Genotypes were evaluated over a two-year period using a RCB design with three replicates. The effects of plant density were investigated in 2012. A with a split-plot design was used, where the A. cruentus accessions (AMES 5148, PI 511719 and PI 643045 constituted the main plots. Plant densities (7.5, 15, 30 and 60 plants m–2 constituted the subplots. Plants were transplanted at the 3-4 true leaf stage. Morphological traits were determined using 5 plants selected from the two central rows of the sampling area. Plots were hand-harvested and cleaned with a mechanical grid with appropriate sieve diameters. A. cruentus was shown to be more suitable to the Central Italy agro-ecological conditions than A. hypochondriacus. The accessions derived from Mexico (PI 477913, PI 576481, PI 643045, PI 643053, and PI 6495079, Guatemala (PI 511719 and Puerto Rico (AMES 5148, had both higher grain yields and a greater stability over the two-year period, with a mean grain production ranging from 2.8 to 3.2 t ha–1. The severe climatic stress in 2012 (high temperatures and aridity, resulted in a 43-60% reduction in seed production compared to that of the previous year. Under these conditions, PI 511719, AMES 26015, AMES 5386, AMES 5148, PI 477913 yielded on average 1.9 t ha–1. Yields of A. hypochondriacus were negligible in both years, probably attributable to greater photoperiod sensitivity, resulting in reduced flowering and delayed maturity. By increasing density up to 60 and 30 plants m–2 for PI 511719 and AMES 5148, respectively, grain production was increased by 55%. As the plant population

O trabalho foi realizado em casa de vegetação, em solo de textura franco-argiloarenosa (20% de argila e 1,9 de matéria orgânica, e as doses dos herbicidas alachlor, diuron, oxyfluorfen, pendimethalin, prometryne, oxyfluorfen, S-metolachlor, trifluralin 450 e trifluralin 600 foram aplicadas aos 30, 20, 10 e 0 dias antes da semeadura das plantas daninhas. Avaliou-se o controle das plantas daninhas após a permanência dos herbicidas no solo por períodos de 0, 10, 20 e 30 dias depois da aplicação dos tratamentos (DAA. A atividade residual de alachlor e prometryne, na dose C95, não foi suficiente para o controle eficiente (>80% das espécies por períodos de até 30 DAA. Quanto ao alachlor, o emprego da dose recomendada não se refletiu em aumento considerável da atividade residual, exceto em relação a A. viridis. A dose recomendada de prometryne proporcionou controle eficiente das espécies até 30 DAA, exceto de A. hybridus. A dose recomendada de oxyfluorfen controlou eficientemente A. hybridus e A. spinosus até 30 DAA, espécies estas que não haviam sido eficientemente controladas pela dose C95. Trifluralin 450 promoveu controle residual eficiente de 30 DAA somente em relação a A. hybridus. Trifluralin 600 foi eficiente no controle de A. hybridus e A. viridis até os 30 DAA e até 29 e 28 DAA para A. lividus e A. spinosus, respectivamente. Clomazone não promoveu controle eficiente das espécies até 30 DAA, exceto de A. viridis. Diuron, pendimethalin e S

O delineamento experimental utilizado foi o de blocos ao acaso em esquema fatorial 5 x 5, envolvendo cinco intervalos entre a última irrigação e a aplicação do herbicida (0, 6, 12, 24 e 48 horas e cinco doses de fomesafen (0,0, 62,5, 125,0, 250,0 e 375,0 g ha-1. Quando as plantas atingiram estádio de quatro pares de folhas, foram aplicados 10 mm de chuva simulada, conforme tratamento previsto. Ao término do período de simulação de chuva, aplicou-se o herbicida utilizando pulverizador costal pressurizado com CO2, com volume de calda de 120 L ha-1. Aos 5, 22, 29 e 43 dias após a aplicação (DAA do herbicida, foi avaliado o controle (por escala visual de A. hybridus e, aos 43 DAA, foram avaliadas também a massa seca das raízes e a da parte aérea. A aplicação de 375,0 g ha-1 de fomesafen proporcionou controle satisfatório de A. hybridus, independentemente do intervalo entre a última irrigação e a aplicação do herbicida ou do teor de umidade do solo, dentro da faixa avaliada. Pulverizações de 250,0 g ha-1 de fomesafen a intervalos menores que 24 horas entre a última irrigação e sua aplicação e/ou em solo com teor de água maior que 0,12 cm³ cm-3 não afetaram a eficácia do herbicida sobre A. hybridus. Aplicações de 125,0 g ha-1 de fomesafen a intervalos menores que 12 horas entre a última irrigação e sua aplicação e/ou em solo com teor de água maior que 0,15 cm³ cm-3 não afetaram a eficácia do herbicida sobre A. hybridus.A greenhouse experiment was carried out to evaluate the efficacy of fomesafen in controlling Amaranthus hybridus grown under different soil humidity levels
