    Full Text Available Abstract Background Rice (Oryza sativa productivity is adversely impacted by numerous biotic and abiotic factors. An approximate 52% of the global production of rice is lost annually owing to the damage caused by biotic factors, of which ~21% is attributed to the attack of insect pests. In this paper we report the isolation, cloning and characterization of Allium sativum leaf agglutinin (asal gene, and its expression in elite indica rice cultivars using Agrobacterium-mediated genetic transformation method. The stable transgenic lines, expressing ASAL, showed explicit resistance against major sap-sucking pests. Results Allium sativum leaf lectin gene (asal, coding for mannose binding homodimeric protein (ASAL from garlic plants, has been isolated and introduced into elite indica rice cultivars susceptible to sap-sucking insects, viz., brown planthopper (BPH, green leafhopper (GLH and whitebacked planthopper (WBPH. Embryogenic calli of rice were co-cultivated with Agrobacterium harbouring pSB111 super-binary vector comprising garlic lectin gene asal along with the herbicide resistance gene bar, both under the control of CaMV35S promoter. PCR and Southern blot analyses confirmed stable integration of transgenes into the genomes of rice plants. Northern and western blot analyses revealed expression of ASAL in different transgenic rice lines. In primary transformants, the level of ASAL protein, as estimated by enzyme-linked immunosorbent assay, varied between 0.74% and 1.45% of the total soluble proteins. In planta insect bioassays on transgenic rice lines revealed potent entomotoxic effects of ASAL on BPH, GLH and WBPH insects, as evidenced by significant decreases in the survival, development and fecundity of the insects. Conclusion In planta insect bioassays were carried out on asal transgenic rice lines employing standard screening techniques followed in conventional breeding for selection of insect resistant plants. The ASAL expressing rice

    Full Text Available Mannose-specific Allium sativum leaf agglutinin encoding gene (ASAL and herbicide tolerance gene (BAR were introduced into an elite cotton inbred line (NC-601 employing Agrobacterium-mediated genetic transformation. Cotton transformants were produced from the phosphinothricin (PPT-resistant shoots obtained after co-cultivation of mature embryos with the Agrobacterium strain EHA105 harbouring recombinant binary vector pCAMBIA3300-ASAL-BAR. PCR and Southern blot analysis confirmed the presence and stable integration of ASAL and BAR genes in various transformants of cotton. Basta leaf-dip assay, northern blot, western blot and ELISA analyses disclosed variable expression of BAR and ASAL transgenes in different transformants. Transgenes, ASAL and BAR, were stably inherited and showed co-segregation in T1 generation in a Mendelian fashion for both PPT tolerance and insect resistance. In planta insect bioassays on T2 and T3 homozygous ASAL-transgenic lines revealed potent entomotoxic effects of ASAL on jassid and whitefly insects, as evidenced by significant decreases in the survival, development and fecundity of the insects when compared to the untransformed controls. Furthermore, the transgenic cotton lines conferred higher levels of resistance (1-2 score with minimal plant damage against these major sucking pests when bioassays were carried out employing standard screening techniques. The developed transgenics could serve as a potential genetic resource in recombination breeding aimed at improving the pest resistance of cotton. This study represents the first report of its kind dealing with the development of transgenic cotton resistant to two major sap-sucking insects.

  3. Allergenicity assessment of Allium sativum leaf agglutinin, a potential candidate protein for developing sap sucking insect resistant food crops.

    Hossain Ali Mondal

    Full Text Available BACKGROUND: Mannose-binding Allium sativum leaf agglutinin (ASAL is highly antinutritional and toxic to various phloem-feeding hemipteran insects. ASAL has been expressed in a number of agriculturally important crops to develop resistance against those insects. Awareness of the safety aspect of ASAL is absolutely essential for developing ASAL transgenic plants. METHODOLOGY/PRINCIPAL FINDINGS: Following the guidelines framed by the Food and Agriculture Organization/World Health Organization, the source of the gene, its sequence homology with potent allergens, clinical tests on mammalian systems, and the pepsin resistance and thermostability of the protein were considered to address the issue. No significant homology to the ASAL sequence was detected when compared to known allergenic proteins. The ELISA of blood sera collected from known allergy patients also failed to show significant evidence of cross-reactivity. In vitro and in vivo assays both indicated the digestibility of ASAL in the presence of pepsin in a minimum time period. CONCLUSIONS/SIGNIFICANCE: With these experiments, we concluded that ASAL does not possess any apparent features of an allergen. This is the first report regarding the monitoring of the allergenicity of any mannose-binding monocot lectin having insecticidal efficacy against hemipteran insects.

  7. Preliminary isotopic study of Lake Asal system (Republic of Djibouti)

    International Nuclear Information System (INIS)

    The saline Lake Asal at 155 m below sea level in the Afar Rift (Republic of Djibouti) is fed mainly by sea water. In spite of the intense evaporation (about 3 m annually), the 18O and deuterium enrichments of the lake water are relatively low, because of the reduced activity of water as a consequence of the high salt content. Isotopic balance of the lake, as well as lithium and sulphate balances, support the hypothesis of leakages from the lake of about 15 to 20% of the inflow. (author)

    1975-01-01

    Granulocyte cytotoxic activity in sera from over 257 patients was shown to be distinct from HL-A lymphocytoxic activity. Granulocyte cytotoxins occur in approximately 25 per cent of sera from patients having leukemia, 45 per cent with aplastic anemia, 22 per cent with kidney disease on hemodialysis, and 19 per cent of pregnant women. By testing sera on the same panel of cells, the granulocyte cytotoxic activity was shown not to be associated with granulocyte agglutination activity or lymphocytotoxic acitivty. It is likely that granulocyte cytotoxins and granulocyte agglutinins will be useful in transfusion and bone marrow transplantation as a separate tool from the more widely used lymphocyte cytotoxicity reaction.

  16. Llama-Derived Single Domain Antibodies Specific for Abrus Agglutinin

    Directory of Open Access Journals (Sweden)

    James P. Carney

    2011-11-01

    Full Text Available Llama derived single domain antibodies (sdAb, the recombinantly expressed variable heavy domains from the unique heavy-chain only antibodies of camelids, were isolated from a library derived from llamas immunized with a commercial abrin toxoid preparation. Abrin is a potent toxin similar to ricin in structure, sequence and mechanism of action. The selected sdAb were evaluated for their ability to bind to commercial abrin as well as abrax (a recombinant abrin A-chain, purified abrin fractions, Abrus agglutinin (a protein related to abrin but with lower toxicity, ricin, and unrelated proteins. Isolated sdAb were also evaluated for their ability to refold after heat denaturation and ability to be used in sandwich assays as both capture and reporter elements. The best binders were specific for the Abrus agglutinin, showing minimal binding to purified abrin fractions or unrelated proteins. These binders had sub nM affinities and regained most of their secondary structure after heating to 95 °C. They functioned well in sandwich assays. Through gel analysis and the behavior of anti-abrin monoclonal antibodies, we determined that the commercial toxoid preparation used for the original immunizations contained a high percentage of Abrus agglutinin, explaining the selection of Abrus agglutinin binders. Used in conjunction with anti-abrin monoclonal and polyclonal antibodies, these reagents can fill a role to discriminate between the highly toxic abrin and the related, but much less toxic, Abrus agglutinin and distinguish between different crude preparations.

  17. Methods and Practices of Urban Filipino Parents in Promoting Mabuting Asal among Preschool Children

    2012-12-01

    Full Text Available This paper is a portion of an ethnographic study conducted in an urbanizing community in Valenzuela City. The study aimed to investigate and discuss the concepts and practices that parents have in promoting mabuting asal or positive social behavior among their preschool children. The participantswere 15 two-parent families with at least two children, one of whom was between ages 3 and 6 years. Seven of the participating families were dualearner while the rest were single-earner. They were visited at home for at leastan hour twice a week for a period of six months. Afterwards, face-to-face interviews were conducted with the parents in each family. Results suggested that the methods that parents use to promote mabuting asal among the young ones can be categorized into three – physical, verbal, and cognitivetypes. Mothers in both income groups used the physical and cognitive types, although single-earner families would use physical methods more often than cognitive ones. On the other hand, fathers in both income groups would useverbal methods more, possibly as a result of their compensating behavior for their own experiences of harsh and coercive upbringing as young children. The study recommends comprehensive, integrative, sensitive, and flexible child-rearing seminars for parents as well as health and day care workers in the community. In terms of methodology, conducting the research in several localities, across different social groups, with a larger sample could provideanother perspective to the relationships between variables utilized in this research.

    Directory of Open Access Journals (Sweden)

    Reverberi Roberto

    2010-08-01

    Full Text Available Abstract Introduction Cold agglutinin disease usually develops as a result of the production of a specific immunoglobulin M auto-antibody directed against the I/i and H antigens, precursors of the ABH and Lewis blood group substances, on red blood cells. Autoimmune and lymphoproliferative disorders, Mycoplasma pneumoniae and other infections can be associated with the production of cold agglutinins. In its classic presentation with haemolytic anaemia and Raynaud's syndrome, cold agglutinin disease is usually idiopathic. Several factors play a role in determining the ability of a cold agglutinin to induce a haemolytic anaemia such as antibody concentration and temperature range, in particular the highest temperature at which antibodies interact with red blood cells. Case presentation A 48-year-old Caucasian man presented to our hospital with symptoms of extreme asthenia caused by severe anaemia. The transfusion of red blood cells (O Rh-positive, started as prescribed by the emergency guidelines in force without pre-transfusion tests, induced fatal haemolysis because of the presence of high levels of anti-H antibodies in his blood, that reacted with the large amount of H antigen in universal (0 red blood cells. Conclusion Emergency transfusion of universal red blood cells (0 Rh-positive or negative is usually accepted by the international guidelines in force in emergency departments. In this report we describe a rare complication caused by the very high concentration in the recipient of cold agglutinins and the activation of the complement system, responsible for red blood cell lysis and consequent fatal cardiovascular shock. We conclude that emergency transfusion of universal red blood cells (0 Rh-positive or negative may be dangerous and its risk should be assessed against the risk of delaying transfusion until the pre-transfusion tests are completed.

  1. Biogenesis and fate of the cell-cell adhesion molecule, agglutinin, during gametogenesis and fertilization of Chlamydomonas reinhardtii

    International Nuclear Information System (INIS)

    Fertilization in Chlamydomonas begins with the species-specific recognition and adhesion between gametes of opposite mating types via agglutinin molecules on the flagellar surface. This adhesion generates a cAMP-mediated sexual signal that initiates the subsequent events of call wall release, mating structure activation, and cell fusion. Although flagella of paired gametes remain attached to each other until the zygote forms, the process is dynamic. Engaged agglutinins rapidly become inactivated and turnover, requiring the constant supply of new agglutinins to replace the lost molecules. A population of cell body associated agglutinins has been postulated to the pool of agglutinins recruited during this turnover. Cell body agglutinins, therefore were identified, purified, localized within the cells and compared to flagellar agglutinins. The relationship between these two agglutinin populations was also examined. Cell body agglutinins were biochemically indistinguishable from the flagellar form with respect to their Mr, sedimentation coefficient, and hydrophobicity elution properties. Functionally, however, these molecules were inactive in situ. The calculated surface density of agglutinins in the cell body and flagellar domains was similar and thus could not explain their functional difference, but two domains contiguous and yet distinctive suggested they may be separated by a functional barrier. To test this, a method was developed, using a monoclonal antibody and cycloheximide, that removed the flagellar agglutinins so movement between the domains could be monitored. Mobilization of agglutinins onto the flagella did not occur unless sexual signaling was induced with cAMP and papaverine

  2. Fluid-controlled faulting process in the Asal Rift, Djibouti, from 8 yr of radar interferometry observations

    2007-01-01

    The deformation in the Asal Rift (Djibouti) is characterized by magmatic inflation, diking, distributed extension, fissure opening, and normal faulting. An 8 yr time line of surface displacement maps covering the rift, constructed using radar interferometry data acquired by the Canadian satellite Radarsat between 1997 and 2005, reveals the aseismic behavior of faults and its relation with bursts of microseismicity. The observed ground movements show the asymmetric subsidence of the inner floor of the rift with respect to the bordering shoulders accommodated by slip on three of the main active faults. Fault slip occurs both as steady creep and during sudden slip events accompanied by an increase in the seismicity rate around the slipping fault and the Fieale volcanic center. Slip distribution along fault strike shows triangular sections, a pattern not explained by simple elastic dislocation theory. These observations suggest that the Asal Rift faults are in a critical failure state and respond instantly to small pressure changes in fluid-filled fractures connected to the faults, reducing the effective normal stress on their locked section at depth.

    Three independent geothermal systems have been identified, so far, in the Asal region of the Republic of Djibouti (i.e. Gale le Goma, Fiale and South of Lake). Six deep wells have been drilled in the region, the first two in 1975 and the others in 1987-88. Well A2 was damaged and wells A4 and A5 encountered impermeable yet very hot (340-365 C) rocks. Wells A1, A2, A3 and A6 produce highly saline (120 g/L TDS) fluids leading to mineral scaling. Well test data indicate that the reservoir might be producing from fractured and porous zones. The estimated permeability-thickness of the deep Gale le Goma reservoir is in the 3-9 darcy-meter range. Lumped-parameter modeling results indicate that well A3 should be operated at about 20 kg/s total flow rate and that injection should be considered to reduce pressure drawdown. The estimated power generation potential of well A3 is 2.5 MWe, and that of all Asal high-temperature hydrothermal systems is between 115 and 329 MWe for a 25-year exploitation period. (author)

  4. Two-dimensional surface velocity field across the Asal Rift (Afar Depression) from 11 years of InSAR data

    Science.gov (United States)

    Tomic, J.; Peltzer, G.; Doubre, C.

    2010-12-01

    We analyze two-dimensional surface velocity maps of the 200x400 km2 region covering the Asal Rift located at the western tip of the Aden Ridge, using the 1997-2008 archive of InSAR data from the RADARSAT satellite. The large phase signal due to turbulent tropospheric conditions over the Afar region is mostly removed from the 11-year average line of sight (LOS) velocity maps, revealing a clear deformation signal across the rift. Assuming the horizontal velocity to be parallel to the direction predicted by the Arabia/Somalia rotation pole (Vigny et al., 2007), we compute the fields of the vertical and horizontal components of the velocity from the ascending and descending line of sight (LOS) velocity maps. The horizontal velocity field shows the divergence between the Arabia and Somalia plates concentrated along the Asal rift, and veering toward the south-west, into the Derella-Gaggade basin system. The Asal rift shoulders open at a rate of ~15 mm/yr, while the horizontal velocity decreases away from the rift down to the plate motion rate of ~11-12 mm/yr. The vertical velocity field shows a ~60 km wide zone of doming centered over the rift associated with shoulder uplift and subsidence of the rift inner floor. The differential movement between the shoulders and the rift floor is accommodated by two main antithetic faults: the south-dipping Fault γ well developed in the topography and the recent north-dipping Fault E with a small topographic scarp. We explain the observed velocity field with 2D-forward and 3D-inverse models combining dislocations of rectangular elements in an elastic half-space. The forward model allows us to estimate the overall geometry and rates of an inflating body at 5 km depth (represented by a combination of a dike and a horizontal sill) and creep on two faults. The least-squares inverse model shows an inflating body located under the Fieale volcano expanding at 2 106 m3/yr. Faults bordering the rift show down-dip and opening motion especially

    Full Text Available Soybean agglutinin (SBA lectin, a protein present in raw soybean meals, can bind to and be extensively endocytosed by intestinal epithelial cells, being nutritionally toxic for most animals. In the present study we show that SBA (5-200 µg/cavity injected into different cavities of rats induced a typical inflammatory response characterized by dose-dependent exudation and neutrophil migration 4 h after injection. This effect was blocked by pretreatment with glucocorticoid (0.5 mg/kg or by co-injection of N-acetyl-galactosamine (100 x [M] lectin, but not of other sugars (100 x [M] lectin, suggesting an inflammatory response related to the lectin activity. Neutrophil accumulation was not dependent on a direct effect of SBA on the macrophage population since the effect was not altered when the number of peritoneal cells was increased or decreased in vivo. On the other hand, SBA showed chemotactic activity for human neutrophils in vitro. A slight increase in mononuclear cells was observed 48 h after ip injection of SBA. Phenotypic analysis of these cells showed an increase in the CD4+/CD8- lymphocyte population that returned to control levels after 15 days, suggesting the development of an immune response. SBA-stimulated macrophages presented an increase in the expression of CD11/CD18 surface molecules and showed some characteristics of activated cells. After intravenous administration, SBA increased the number of circulating neutrophils and inhibited in a dose-dependent manner the neutrophil migration induced by ip injection of carrageenan into peritoneal cavities. The co-injection of N-acetyl-galactosamine or mannose, but not glucose or fucose, inhibited these effects. The data indicate that soybean lectin is able to induce a local inflammatory reaction but has an anti-inflammatory effect when present in circulating blood

These cold agglutinins were the cause for diagnostic confusion and resulted in extensive workup and unnecessary therapeutic precautions. A thirty two year old female with Guillain-Barre syndrome was admitted in the ICU and serial work-up showed markedly low levels of platelets. The patient had no symptoms of bleeding and patient was investigated extensively for deciphering the etiology of low platelet count. In-vitro clumping of platelets was suspected and in-vitro studies showed marked clumping of platelets with ethylene-diamine-tetra-acetic acid, citrate and heparinized samples. The manual platelet count was found to be within normal limits. Thrombocytopenia as a result of platelet cold agglutinins is a rare cause of in-vitro low platelet counts. No clinical problems have been reported due to the same.

    One of the six predicted Proteus mirabilis autotransporters (ATs), ORF c2341, is predicted to contain a serine protease motif and was earlier identified as an immunogenic outer membrane protein in P. mirabilis. The 3.2 kb gene encodes a 117 kDa protein with a 58-amino-acid-long signal peptide, a 75-kDa-long N-terminal passenger domain and a 30-kDa-long C-terminal translocator. Affinity-purified 110 kDa AT exhibited chymotrypsin-like activity and hydrolysed N-Suc-Ala-Ala-Pro-Phe-pNa and N-Suc-Ala-Ala-Pro-Leu-pNa with a K(M) of 22 muM and 31 muM, respectively, under optimal pH of 8.5-9.0 in a Ca(2+)-dependent manner. Activity was inhibited by subtilase-specific inhibitors leupeptin and chymostatin. Both the cell-associated and purified form elicited cytopathic effects on cultured kidney and bladder epithelial cells. Substrate hydrolysis as well as cytotoxicity was associated with the passenger domain and was compromised upon mutation of any of the catalytic residues (Ser366, His147 and Asp533). At alkaline pH and optimal cell density, the AT also promoted autoaggregation of P. mirabilis and this function was independent of its protease activity. Cytotoxicity, autoaggregation and virulence were significantly reduced in an isogenic pta mutant of P. mirabilis. Proteus toxic agglutinin (Pta) represents a novel autotransported cytotoxin with no bacterial homologues that works optimally in the alkalinized urinary tract, a characteristic of urease-mediated urea hydrolysis during P. mirabilis infection.

    Cross-reaction agglutinin titers to Brucella abortus antigen were found in 42 of 128 tularemia serum specimens, and cross-reaction titers to Francisella tularensis antigen were found in 8 of 34 brucellosis serum specimens. The cross-reaction titers were reduced to 10 or less by dithiothreitol, suggesting that the titers are due to immunoglobulin M antibody.

  16. Effect of in vivo γ-irradiation on the binding of wheat germ agglutinin on lymphocyte plasma membranes

    International Nuclear Information System (INIS)

    Using quantitative fluorimetry with fluoresceinated wheat germ agglutinin, we have been able to investigate in vivo gamma radiation-induced damage at the outer membrane level of rat splenic lymphocytes, namely damage to the glucosidic moieties of membrane glycoproteins and glycolipids. This paper demonstrates that below an irradiation level of 1 gray (Gy), removal of sialic acid is the major feature leading to new exposed specific binding sites for wheat germ agglutinin, since this lectin is specific for sialic acid and N-acetyl-D-glucosamine. Our studies also suggest that above 1 Gy of irradiation more internal damage occurs, since we observed a striking decrease in wheat germ agglutinin binding sites. (orig.)

    Full Text Available Background : ABO incompatibility in maternal-fetal relationship has been shown to cause hemolytic disease of the newborn (HDNB; a survey which is not yet done in this locality. Aim: Frequency of ABO blood group maternal-fetal incompatibility, maternal iso-agglutinins, and immune agglutinins quantitation was carried out in Osogbo, Osun State, South-West of Nigeria. Settings and Designs : A total of 260 subjects comprising 130 postpartum mothers within the age range of 22-35 years having good obstetrics history and normal delivery, with their 130 neonate babies were used for the study. Materials and Methods : ABO cell and serum groupings were carried out on the subjects using standard antisera and cells with appropriate controls. Direct Coomb′s Test was carried out on neonate red cells. Antibody quantitation by double dilution on the maternal serum using red cells containing corresponding antigen to the antibody was determined. A titer, which is the reciprocal of the highest dilution showing agglutination by Indirect Coombs Test, was determined. Another batch of sera was pretreated with 2-mecarptoethanol before determining the titer. Statistical Analysis: The distribution study results obtained were compared in percentages, whereas the antibodies quantitation was expressed as titers using the mode of the titers for compariso-agglutininsn. Results and Conclusions : Thirty-eight percent (50 mothers were ABO incompatible with their babies, whereas 62% (80 mothers were compatible. The distribution of blood groups in the compatible population showed blood group O (45%; A (30%; B (20%; and AB (5%. Mothers O, A, and B carrying incompatible babies had a frequency of 24% each, whereas mothers AB had 28%. Serologist differences occur in maternal ABO antibodies of corresponding incompatible baby ABO antigens. A high incidence of ABO maternal-fetal incompatibility observed without detection of immune agglutinins is indicative of a rare incidence of HDNB due

  2. Enrichment for CFU-C from murine and human bone marrow using soybean agglutinin

    International Nuclear Information System (INIS)

    Mouse bone marrow and spleen cells agglutinated by soybean agglutinin (SBA) or peanut agglutinin (PNA) were previously shown to be enriched for spleen colony-forming cells (CFU-S) and sufficiently depleted of graft-versus-host reaction producing cells to allow hematologic reconstitution of lethally irradiated allogeneic recipient mice. A similar enrichment for cells capable of forming colonies in soft agar culture (CFU-C) has now been found in the SBA-agglutinated fraction of mouse bone marrow cells, in contrast to the finding that in human bone marrow the majority of the CFU-C are in the fraction not agglutinated by SBA. Cytofluorometric studies with fluorescein-labeled SBA (FITC-SBA) revealed that the majority of both mouse and human bone marrow cells bind the lectin. Experiments mixing the human marrow fractions separated by SBA reveal that true enrichment for CFU-C is achieved in the unagglutinated fraction, as opposed to a possible depletion of a suppressor cell population. Granulocytic, monocytic, and mixed cell colonies were all enriched in the SBA-unagglutinated cell fraction from human bone marrow

    Full Text Available Cold agglutinins are of unique relevance in cardiac surgerybecause of the use of hypothermic cardiopulmonary bypass (CPB. Cold autoimmune diseases are defined by the presence of abnormal circulating proteins (usually IgM or IgA antibodies that agglutinate in response to a decrease in body temperature. These disorders include cryoglobulinemia and cold hemagglutinin disease.Immunoglobulin M autoantibodies to red blood cells, which activateat varying levels of hypothermia, can cause catastrophic hemagglutination,microvascular thrombosis, or hemolysis. Management of anesthesia in these patients includes strict maintenance of normothermia. Patients scheduled for the surgery requiring cardiopulmonary bypass present significant challenges. Use of systemic hypothermia may be contraindicated, and cold cardioplegia solutions may precipitate intracoronary hemagglutination with consequent thrombosis, ischemia, or infarction. Management of CPB andmyocardial protection requires individualized planning. We describea case of MV repair and CABG in a patient with high titercold agglutinins and high thermal amplitude for antibody activation.Normothermic CPB and continuous warm blood cardioplegia weresuccessfully used.

    The aphid is one of the most serious pests that causes damage to crops worldwide. Lectins from Araceae plant had been proved useful to control the aphid. Herein, the full-length cDNA of Monstera deliciosa agglutinin (mda) gene was cloned and then introduced into tobacco and the influence of the expression of mda in transgenic tobacco against peach-potato aphids (Myzus persicae) was investigated. Among 92 regenerated plants, 59 positive tobacco lines were obtained. Real-time PCR assays and aphid bioassay test revealed that there is a positive correlation between the expression level of mda and the inhibitory effect on peach-potato aphids. The average anti-pests ability of mda transgenic tobacco was 74%, which was higher than that of other reported lectins from Araceae plant. These results indicated that MDA is one of promising insect resistance proteins selected for the control of peach-potato aphids. PMID:22660606

    An optical biosensor with a stirred cuvette has been used to monitor the interaction of immobilized wheat germ agglutinin (WGA) with two water-soluble cationic porphyrins. The association constants (Ka) of the free base porphyrin and its Zn(Ⅱ) complex form were 2.66 and 27.31×105 L/mol at 20 ℃ respectively. The interactions of the free base porphyrin were further investigated at temperatures between 15 ℃ and 37 ℃. The thermodynamics parameters, changes in free energy, enthalpy and entropy, were -31.23, 22.92, 54.15 kJ/mol respectively. The heat capacity change was -355.53 J·mol-1·K-1. The binding was driven by entropic contribution, and showed strong enthalpy-entropy compensation. It was governed primarily by hydrophobic forces.

  9. Dynamic light scattering study of peanut agglutinin: Size, shape and urea denaturation

    2006-12-01

    Peanut agglutinin (PNA) is a homotetrameric protein with a unique open quaternary structure. PNA shows non-two state profile in chaotrope induced denaturation. It passes through a monomeric molten globule like state before complete denaturation (Reddy et al 1999). This denaturation profile is associated with the change in hydrodynamic radius of the native protein. Though the molten globule-like state is monomeric in nature it expands in size due to partial denaturation. The size and shape of the native PNA as well as the change in hydrodynamic radius of the protein during denaturation has been studied by dynamic light scattering (DLS). The generation of two species is evident from the profile of hydrodynamic radii. This study also reveals the extent of compactness of the intermediate state.

    In order to find new insect resistance genes, four homologous cDNAs, hta-a, hta-b, hta-c and hta-d with lengths of 775, 718, 784 and 752 bp, respectively (GenBank accession numbers AF477031-AF477034), were isolated from a tuber cDNA expression library of Helianthus tuberosus L. Sequence analysis revealed that all four cDNAs contain an open reading frame of 444 bp, coding a polypeptide of 147 amino acid residues, and that the sequences of the cDNAs are very similar to those of the mannose-binding agglutinin genes of the jacalin-related family. In hemagglutination reactions and hapten inhibition assays, affinity-purified HTA (Helianthus tuberosus agglutinin) from induced Escherichia coli BL21(DE3) expressing GST-HTA shows hemagglutination ability and a higher carbohydrate-binding ability for mannose than other tested sugars.Trypsin inhibitory activity was detected in the crude extracts of induced E. coli BL21(DE3)expressing HTA,and was further verified by trypsin inhibitory activity staining on native polyacrylamide gel. The mechanism of interaction between HTA and trypsin was studied by molecular modeling. We found that plenty of hydrogen bonds and electrostatic interactions can be formed between the supposed binding sites of HTA-b and the active site of trypsin, and that a stable HTA/trypsin complex can be formed. The results above imply that HTA might be a bifunctional protein with carbohydrate-binding activity and trypsin inhibitory activity. Moreover,Northern blotting analysis demonstrated that hta is predominantly expressed in tubers of H. tuberosus, very weakly expressed in stems, but not expressed at all in other tissues. Southern blotting analysis indicated that hta is encoded by a multi-gene family. The insect resistance traits have been described in another paper.

    Full Text Available Background: Brucellosis is a zoonotic disease of worldwide distribution and has great economic importance. Despite its control in many countries, it remains endemic in Iran. Brucellosis was investigated in many high risk occupational groups; however, few studies on the prevalence of brucellosis among blood donors are available. To determine the seroprevalence of brucellosis antibodies in blood donors, a serological study was carried out in central province of Iran.Materials and Methods: A total of 897 healthy blood donors with mean age 37.23 ± 10.9 years were enrolled in the study. Laboratory tests including Standard Tube Agglutination Test (STA and 2-mercaptoethanol (2ME agglutination were checked in all samples. STA dilution ≥ 1:80, and in the presence of 2-mercaptoethanol (2ME agglutination ≥ 20 was considered positive.Results: Out of 897 cases, 11.9% were inhabitants of rural areas. 41.5% had history of consumption of unpasteurized dairy products and 9.3% had history of contact with domestic animals. A very low level of Brucella agglutinins was present in 3(0.33% of the samples and only one sample (0.11% was found to be truly positive for Brucella agglutinins. 2ME was negative in all samples. None of these 4 subjects showed signs and symptoms of brucellosis in 6 months follow-up.Conclusion: On the basis of our data, brucellosis has no epidemiological and clinical importance in our blood donors; therefore, it is not recommended to perform screening tests such as, STA and 2ME to identify brucellosis antibodies in the sera of blood donors.

    2010-05-01

    A 66-kDa lectin (OmA) was purified from the serum of the Yucatan peninsula endemic octopus (Octopus maya) by a single step affinity chromatography on glutaraldehyde-fixed stroma from rat erythrocytes. OmA corresponds to 0.8% of the total circulating protein in the hemolymph; it is composed of three equal subunits of 22kDa each, and 7.4% of linked carbohydrates. The amino acids' composition indicated that agglutinin contained mainly aspartic and glutamic acids, and cysteine and methionine were identified in minor proportion. OmA agglutinates mainly rat, guinea pig, and rabbit erythrocytes, and this activity is partially inhibited by galactosamine, melobiose, galacturonic acid, mannose, and methyl alpha and beta galactosides. Hemagglutinating activity is not dependent on divalent cations, such as Ca(2+), Mg(2+), or Mn(2+). The OmA subunits showed no identity for any lectin in databases but partial identity with the type A hemocyanin from Octopus dolfleini hemolymph; the main similarities are related to tyrosinase domains and copper A and B sites that conform to the oxygen-binding site of hemocyanin.

  19. Transneuronally transported wheat germ agglutinin labels glia as well as neurons in the rat visual system

    International Nuclear Information System (INIS)

    Following intraocular injection in adult rats of 125I-labeled wheat germ agglutinin (I-WGA), the ultrastructural distribution of label in the superior colliculus and lateral geniculate was examined by electron microscope autoradiography. Three days after injection, 5.4% of the label in the lateral geniculate was associated with neuronal perikarya, and 3.6% was associated with glial perikarya. The corresponding figures for the superior colliculus were 5.1% and 0.8%. When the data were expressed as number of grains per micron 2 cytoplasm, there was no statistically significant difference between the grain density over neuronal or glial cytoplasm in either the lateral geniculate or the superior colliculus. A statistical analysis of the distance between the silver grains and the cell membranes showed that in both neurons and glia, the observed labeling was the product of internalized I-WGA and not the result of scatter from the neuropil or from label bound to the surface of the cells. These results indicate that much of the WGA released from axons and axon terminals is not confined to a specific ''transsynaptic'' pathway, but produces a generalized labeling of nearby cells, much like a microinjection of WGA into the region

  3. Comparative influence study of gate-formation structuring on Al0.22Ga0.78As/In0.16Ga0.84As/Al0.22Ga0.78As double heterojunction high electron mobility transistors

    International Nuclear Information System (INIS)

    Pseudomorphic Al0.22Ga0.78As/In0.16Ga0.84As/Al0.22Ga0.78As double heterojunction high electron mobility transistors (DH-HEMTs) fabricated with different gate-formation structures of a single-recess gate (SRG), a double-recess gate (DRG) and a field-plate gate (FPG) were comparatively investigated. FPG devices show the best breakdown characteristics among these devices due to great reduction in the peak electric field between the drain and gate electrodes. The measured gate–drain breakdown voltages defined at a 1 mA mm−1 reverse gate–drain current density were −15.3, −19.1 and −26.0 V for SRG, DRG and FPG devices, respectively. No significant differences in their room-temperature common-source current–voltage characteristics were observed. However, FPG devices exhibit threshold voltages being the least sensitive to temperature. Threshold voltages as a function of temperature indicate a threshold-voltage variation as low as −0.97 mV K−1 for FPG devices. According to the 2.4 GHz load–pull power measurement at VDS = 3.0 V and VGS = −0.5 V, the saturated output power (POUT), power gain (GP) and maximum power-added efficiency (PAE) were 10.3 dBm/13.2 dB/36.6%, 11.2 dBm/13.1 dB/39.7% and 13.06 dBm/12.8 dB/47.3%, respectively, for SRG, DRG and FPG devices with a pi-gate in class AB operation. When the FPG device is biased at a VDS of 10 V, the saturated power density is more than 600 mW mm−1

    The dietary change resulting from the domestication of plant and animal species and development of agriculture at different locations across the world was one of the most significant changes in human evolution. An increase in dietary carbohydrates caused an increase in dental caries following the development of agriculture, mediated by the cariogenic oral bacterium Streptococcus mutans. Salivary agglutinin [SAG, encoded by the deleted in malignant brain tumors 1 (DMBT1) gene] is an innate immune receptor glycoprotein that binds a variety of bacteria and viruses, and mediates attachment of S. mutans to hydroxyapatite on the surface of the tooth. In this study we show that multiallelic copy number variation (CNV) within DMBT1 is extensive across all populations and is predicted to result in between 7-20 scavenger-receptor cysteine-rich (SRCR) domains within each SAG molecule. Direct observation of de novo mutation in multigeneration families suggests these CNVs have a very high mutation rate for a protein-coding locus, with a mutation rate of up to 5% per gamete. Given that the SRCR domains bind S. mutans and hydroxyapatite in the tooth, we investigated the association of sequence diversity at the SAG-binding gene of S. mutans, and DMBT1 CNV. Furthermore, we show that DMBT1 CNV is also associated with a history of agriculture across global populations, suggesting that dietary change as a result of agriculture has shaped the pattern of CNV at DMBT1, and that the DMBT1-S. mutans interaction is a promising model of host-pathogen-culture coevolution in humans.

    Smith, L; Hochmuth, R M

    1982-07-01

    The elasticity and viscosity of the human erythrocyte membrane were measured as a function of the concentration of wheat germ agglutinin (WGA) in a suspending solution containing 1 mg/ml albumin, approximately 5 X 10(5) cells/ml and between 0.0 and 0.2 microgram/ml WGA. Membrane elasticity was characterized by the elastic shear modulus, which provided a measure of the resistance of the membrane to constant-area elastic deformations that occurred in the membrane plane. The elastic shear modulus was determined by aspirating a portion of the membrane into a micropipette and measuring the extension of the membrane into the pipette as a function of the suction pressure. The results indicated no significant change in shear modulus for concentrations of WGA between 0.0 and 0.2 microgram/ml. Membrane viscosity was characterized by the coefficient of surface viscosity, which, in effect, was a measure of the membrane's resistance to rates of deformation. This coefficient was determined from the time required for an erythrocyte to recover its undeformed shape after it had been elongated by the application of an equal and opposite force applied at diametrically opposite points on the erythrocyte rim. The value for the coefficient of surface viscosity was found to increase by a factor of almost three when the WGA concentration was increased from 0.0 to 0.2 microgram/ml. These results indicated that, in the presence of albumin, WGA can increase membrane dissipation (viscosity) without altering the structural rigidity (elasticity) of the membrane. PMID:6896878

    2002-01-01

    Salivary agglutinin is encoded by DMBT1 and identical to gp-340, a member of the scavenger receptor cysteine-rich (SRCR) superfamily. Salivary agglutinin/DMBT1 is known for its Streptococcus mutans agglutinating properties. This 300-400 kDa glycoprotein is composed of conserved peptide motifs: 14...... containing exclusively SRCR and SID domains that binds to S. mutans. To define more closely the S. mutans-binding domain, consensus-based peptides of the SRCR domains and SIDs were designed and synthesized. Only one of the SRCR peptides, designated SRCRP2, and none of the SID peptides bound to S. mutans....... Strikingly, this peptide was also able to induce agglutination of S. mutans and a number of other bacteria. The repeated presence of this peptide in the native molecule endows agglutinin/DMBT1 with a general bacterial binding feature with a multivalent character. Moreover, our studies demonstrate for the...

    Full Text Available Bekasam is well known in Indonesia as one of fermented fish product. Several fermented products generate lactic acid bacteria (LAB which has probiotic potential with beneficial effects on human health. However, In Indonesia, the research on LAB isolated from fermented fish product, including bekasam, is still rarely conducted. The aim of this study was to evaluate the probiotic potential of LAB isolated from bekasam. Two LAB isolates namely NS(5 and NS(6 were selected based on their resistance to gastric pH (pH 2.0, intestinal pH (pH 7.2 and bile salts (0.5% oxgal. Pathogenic test, antimicrobial activity test, characterization and identification of the isolats were also performed respectively. The result showed that NS(5 isolate survived at pH 2.0, pH 7.2 and bile salts (oxgal. It was obtained that NS(5 isolate was non pathogenic bacteria which exhibited antimicrobial activity against Salmonella Typhimurium ATCC 14028 and Escherichia coli. The characterization result showed that NS(5 isolate was Gram-positive bacteria, rod-shaped, non-endospore producer, negative catalase, homofermentative, non motile, having an amilolitik as well as lipolitik activity and able to grow at 30-37°C, NaCl 2-7% dan pH 4.4-9.6. Isolate NS(5 isolate was then identified as Lactobacillus plantarum 1 strain with 99.9% of similarity. Meanwhile, NS(6 isolate was not able to survive in the medium containing bile salts (oxgal, therefore it was not categorized as a probiotic candidate.

    To complete the revamp of CERN’s Council Chamber, a new exhibition is being installed just in time for the June Council meetings.   Panels will showcase highlights of CERN’s history, using some of the content prepared for the exhibitions marking 50 years of the PS, which were displayed in the main building last November. The previous photo exhibition in the Council Chamber stopped at the 1970s. To avoid the new panels becoming quickly out of date, photos are grouped together around specific infrastructures, rather than following a classic time-line. “We have put the focus on the accelerators – the world-class facilities that CERN has been offering researchers over the years, from the well-known large colliders to the lesser-known smaller facilities,” says Emma Sanders, who worked on the content. The new exhibition will be featured in a future issue of the Bulletin with photos and an interview with Fabienne Marcastel, designer of the exhibit...

  17. Studies on glycoproteins produced by wild type and wheat germ agglutinin-resistant B16 mouse melanoma cells

    International Nuclear Information System (INIS)

    Two variants of B16 mouse melanoma cells have been selected in serum-free medium for their resistance to toxic levels of wheat germ agglutinin isolation 1 (WGA). Chromosome analysis and characteristic melanin production showed that the variants are derived from the parent mouse melanoma cell lines. However, the two variants were less tumorigenic in mice compared to the parent B16 mouse melanoma cells. The variants showed a marked decrease in cell agglutination with WGA. Cell agglutination with recin and peanut lectin was not different between the three cell lines, but the two variants showed a slight increase in agglutination with concanavalin A. The binding of 125I-labeled wheat germ agglutinin to the two variant cells was reduced compared to that of the parent cell. Glycoproteins secreted or shed by the three lines were isolated after growth in serum-free medium in the presence of [3He]glucosamine and bovine serum albumin (1%). These metabolically labeled products were fractionated on the basis of their interaction with WGA-Sepharose (2 mg/ml). The WGA-Sepharose affinity chromatographic data suggested a decrease in WGA-binding glycoprotein(s) secreted to the medium by the two variants. The WGA-bound glycoproteins from the two variants upon SDS-PAGE revealed three bands of approximate molecular weights, 92,000, 56,000, and 42,000, none of which were present in the parent cell line (50,000 molecular weight)

    Presenting the complexity of geosciences to the public via the Internet poses a number of challenges. For example, utilizing various - and sometimes redundant - Web 2.0 tools can quickly devour limited time. Do you tweet? Do you write press releases? Do you create an exhibit or concept map? The presentation will provide participants with a context for utilizing Web 2.0 tools by briefly highlighting methods of online scientific communication across several dimensions. It will address issues of: * breadth and depth (e.g. from narrow topics to well-rounded views), * presentation methods (e.g. from text to multimedia, from momentary to enduring), * sources and audiences (e.g. for experts or for the public, content developed by producers to that developed by users), * content display (e.g. from linear to non-linear, from instructive to entertaining), * barriers to entry (e.g. from an incumbent advantage to neophyte accessible, from amateur to professional), * cost and reach (e.g. from cheap to expensive), and * impact (e.g. the amount learned, from anonymity to brand awareness). Against this backdrop, the presentation will provide an overview of two methods of online information dissemination, exhibits and concept maps, using the WebExhibits online museum (www.webexhibits.org) and SpicyNodes information visualization tool (www.spicynodes.org) as examples, with tips on how geoscientists can use either to communicate their science. Richly interactive online exhibits can serve to engage a large audience, appeal to visitors with multiple learning styles, prompt exploration and discovery, and present a topic’s breadth and depth. WebExhibits, which was among the first online museums, delivers interactive information, virtual experiments, and hands-on activities to the public. While large, multidisciplinary exhibits on topics like “Color Vision and Art” or “Calendars Through the Ages” require teams of scholars, user interface experts, professional writers and editors

In organizing this exhibition, the National Nuclear Energy Commission of Mexico was assisted by the International Atomic Energy Agency which has placed its second mobile radioisotope laboratory at the disposal of the Mexican authorities. In many States of the Republic, the visit of the mobile laboratory has given a powerful impetus to atomic training and research. Universities have made use of the laboratory for the training of young scientists in the basic isotope techniques. As a sequel to the work initiated with its aid, some universities are planning to start regular training courses in this field. The laboratory, which is a gift to the Agency from the United States, has been put to its first assignment in Mexico. It will shortly be sent to Argentina for a period of six months for use in training courses. IAEA's first mobile radioisotope unit, also donated by the United States, has been used for training purposes in Austria, the Federal Republic of Germany, Greece and Yugoslavia, and has now been sent to the Far East

    There have been some limitations on early diagnosis of Mycoplasma pneumoniae (MP) infection because of no immunoglobulin M (IgM) responses and variable detection rates of polymerase chain reaction in the early stage of the disease. We wanted to discuss regarding early diagnostic method using short-term paired titration of MP-specific IgM and cold agglutinins (CAs) in the early stage of MP pneumonia.The participants of this study were 418 children with MP pneumonia during 2 recent epidemics (2006-2007 and 2011), and they were diagnosed by an anti-MP IgM antibody test (Serodia Myco II) examined twice during hospitalization at presentation and around discharge (mean of 3.4 ± 1.3 days apart). CA titers were simultaneously examined twice during study period. Anti-MP IgM antibody titer ≥1:40 and CA titer ≥1:4 were considered positive, respectively. The relationships between 2 IgM antibodies in the early stage were evaluated.Regarding MP-specific antibody titers, 148 patients showed a seroconversion, 245 patients exhibited increased titers, and 25 patients had unchanged higher titers (≥1:640) during hospitalization. The median MP-specific antibody titers at each examination time were 1:80 and 1:640, respectively; those of CAs were 1:8 and 1:32, respectively. Illness duration prior to admission showed a trend of association with both titers, and patients with shorter illness duration had a higher rate of negative titers or lower titers at each examination time. CAs and MP-specific antibody titers were correlated in the total patients at presentation and at 2nd examination (P < 0.001, respectively), and the diagnostic corresponding rates of CAs to IgM antibody test were 81% to 96% in patient subgroups.Short-term paired MP specific-IgM determinations in the acute stage may be used as a definitive diagnostic method for MP pneumonia. Paired CA titers showed a correlation with MP-specific antibody titers, suggesting they can be used as an adjuvant diagnostic

    Abrus agglutinin (AGG), a plant lectin isolated from the seeds of Abrus precatorius, has documented antitumor and immunostimulatory effects in murine models. To examine possible antitumor activity against breast cancer, we established human breast tumor xenografts in athymic nude mice and intraperitoneally administered AGG. AGG inhibited tumor growth and angiogenesis as confirmed by monitoring the expression of Ki-67 and CD-31, respectively. In addition, TUNEL positive cells increased in breast tumors treated with AGG suggesting that AGG mediates anti-tumorigenic activity through induction of apoptosis and inhibition of angiogenesis. On a molecular level, AGG caused extrinsic apoptosis through ROS generation that was AKT-dependent in breast cancer cells, without affecting primary mammary epithelial cells, suggesting potential cancer specificity of this natural compound. In addition, using HUVECs, AGG inhibited expression of the pro-angiogenic factor IGFBP-2 in an AKT-dependent manner, reducing angiogenic phenotypes both in vitro and in vivo. Overall, the present results establish that AGG promotes both apoptosis and anti-angiogenic activities in human breast tumor cells, which might be exploited for treatment of breast and other cancers.

    Four kinds of tetravalent double-headed glycoclusters [(LacNAc)4-DHGs] were designed with linkers of varying lengths consisting of alkanedioic carboxyamido groups (C6, C12, C18 and C24) between two bi-antennary LacNAc-glycosides. These glycoclusters served as high-affinity cross-linking ligands for the LacNAc-binding lectin Erythrina cristagalli agglutinin (ECA). The binding activity and cross-linking between each ligand and ECA were characterized by a hemagglutination inhibition (HI) assay, isothermal titration calorimetry (ITC), a quantitative precipitation assay and dynamic light scattering (DLS). For the precipitation assay and DLS measurement, the synthesized (LacNAc)4-DHGs were found to be capable of binding and precipitating the ECA as multivalent ligands. ITC analysis indicated the binding of (LacNAc)4-DHGs was driven by a favorable enthalpy change. Furthermore, the entropy penalty from binding (LacNAc)4-DHGs clearly decreased in a spacer length-dependent manner. The binding affinities of flexible (LacNAc)4-DHGs (C18 and C24) with long spacers were found to be more favorable than those of the clusters having short spacers (C6 and C12). These results were supported by molecular dynamics simulations with explicit water molecules for the tetravalent glycoclusters with ECA. We concluded that the subtle modification in the epitope-presenting scaffolds exerts the significant effect in the recognition efficiency involved in the LacNAc moieties by ECA. PMID:26672510

  19. Effects of wheat germ agglutinin on human gastrointestinal epithelium: Insights from an experimental model of immune/epithelial cell interaction

    International Nuclear Information System (INIS)

    Wheat germ agglutinin (WGA) is a plant protein that binds specifically to sugars expressed, among many others, by human gastrointestinal epithelial and immune cells. WGA is a toxic compound and an anti-nutritional factor, but recent works have shown that it may have potential as an anti-tumor drug and as a carrier for oral drugs. To quantitate the toxicity threshold for WGA on normal epithelial cells we previously investigated the effects of the lectin on differentiated Caco2 cells, and showed that in the micromolar range of concentrations WGA could alter the integrity of the epithelium layer and increase its permeability to both mannitol and dextran. WGA was shown to be uptaken by Caco2 cells and only ∼ 0.1% molecules were observed to cross the epithelium layer by transcytosis. Here we show that at nanomolar concentrations WGA is unexpectedly bioactive on immune cells. The supernatants of WGA-stimulated peripheral blood mononuclear cells (PBMC) can alter the integrity of the epithelium layer when administered to the basolateral side of differentiated Caco2 cells and the effects can be partially inhibited by monoclonal antibodies against IL1, IL6 and IL8. At nanomolar concentrations WGA stimulates the synthesis of pro-inflammatory cytokines and thus the biological activity of WGA should be reconsidered by taking into account the effects of WGA on the immune system at the gastrointestinal interface. These results shed new light onto the molecular mechanisms underlying the onset of gastrointestinal disorders observed in vivo upon dietary intake of wheat-based foods.

    Platelet cold agglutinins (PCA) cause pseudothrombocytopenia, spurious thrombocytopenia due to ex vivo platelet clumping, complicating clinical diagnosis, but mechanisms and consequences of PCA are not well defined. Here, we characterised an atypical immunoglobulin (Ig)M PCA in a 37-year-old woman with lifelong bleeding and chronic moderate thrombocytopenia, that induces activation and aggregation of autologous or allogeneic platelets via interaction with platelet glycoprotein (GP)VI. Patient temperature-dependent pseudothrombocytopenia was EDTA-independent, but was prevented by integrin αIIbβ3 blockade. Unstimulated patient platelets revealed elevated levels of bound IgM, increased expression of activation markers (P-selectin and CD63), low GPVI levels and abnormally high thromboxane (TX)A2 production. Patient serum induced temperature- and αIIbβ3-dependent decrease of platelet count in allogeneic donor citrated platelet-rich plasma (PRP), but not in PRP from Glanzmann's thrombasthenia or afibrinogenaemia patients. In allogeneic platelets, patient plasma induced shape change, P-selectin and CD63 expression, (14)C-serotonin release, and TXA2 production. Activation was not inhibited by aspirin, cangrelor or blocking anti-Fc receptor (FcγRIIA) antibody, but was abrogated by inhibitors of Src and Syk, and by a soluble GPVI-Fc fusion protein. GPVI-deficient platelets were not activated by patient plasma. These data provide the first evidence for an IgM PCA causing platelet activation/aggregation via GPVI. The PCA activity persisted over a five-year follow-up period, supporting a causative role in patient chronic thrombocytopenia and bleeding. PMID:25994029

    The purpose of this study was to investigate the potentiation of the anticancer activity and enhanced cellular retention of paclitaxel-loaded PLGA nanoparticles after surface conjugation with wheat germ agglutinin (WGA) against colon cancer cells. Glycosylation patterns of representative colon cancer cells confirmed the higher expression levels of WGA-binding glycoproteins in the Caco-2 and HT-29 cells, than in the CCD-18Co cells. Cellular uptake and in vitro cytotoxicity of WNP (final formulation) against colon cell lines was evaluated alongside control formulations. Confocal microscopy and quantitative analysis of intracellular paclitaxel were used to monitor the endocytosis and retention of nanoparticles inside the cells. WNP showed enhanced anti-proliferative activity against Caco-2 and HT-29 cells compared to corresponding nanoparticles without WGA conjugation (PNP). The greater efficacy of WNP was associated with higher cellular uptake and sustained intracellular retention of paclitaxel, which in turn was attributed to the over-expression of N-acetyl-D-glucosamine-containing glycoprotein on the colon cell membrane. WNP also demonstrated increased intracellular retention in the Caco-2 (30% of uptake) and HT-29 (40% of uptake) cells, following post-uptake incubation with fresh medium, compared to the unconjugated PNP nanoparticles (18% in Caco-2) and (27% in HT-29), respectively. Cellular trafficking study of WNP showed endocytosed WNP could successful escape from the endo-lysosome compartment and release into the cytosol with increasing incubation time. It may be concluded that WNP has the potential to be applied as a targeted delivery platform for paclitaxel in the treatment of colon cancer. PMID:20804835

  3. Differences in the labeling of axons of passage by wheat germ agglutinin after uptake by cut peripheral nerve versus injections within the central nervous system

    International Nuclear Information System (INIS)

    Injections of a radiolabeled derivative of wheat germ agglutinin (WGA) in the subcortical white matter of the cerebral cortex in mice do not give rise to autoradiographic labeling of axon systems coursing through this fiber mass. Exposing the cut-end of mouse tibial nerve to WGA does, however, produce labeling within dorsal root ganglia and the spinal cord. These findings are discussed with consideration for dissimilarity in mode of central versus peripheral administration of the tracer, as well as in the light of potential relative differences in the uptake and transport of WGA and HRP.

    Full Text Available Abstract Background The TF (Thomson – Friedenreich blood group antigen behaves as an onco-foetal carcinoma-associated antigen, showing increased expression in malignancies and its detection and quantification can be used in serologic diagnosis mainly in adenocarcinomas. This study was undertaken to analyze the sera and tissue level detectable mucin-type glycoprotein (TF-antigen by Peanut agglutinin (PNA and its diagnostic index in serum as well tissues of human esophageal squamous cell carcinoma as marker. Results We examined 100 patients for serological analysis by Enzyme Linked Lectin Assay (ELISA and demonstrated a sensitivity of 87.5%, specificity of 90% and a positive predictive value of 95%. The immuno-histochemical localization of TF antigen by Fluorescence Antigen Technique (FAT in 25 specimens of normal esophageal squamous epithelium specimens and 92 specimens with different grades of, allowed a quicker and more precise identification of its increased expression and this did not correlate with gender and tumor size. There was a positive correlation between membrane bound TF antigen expression with different histological progression, from well differentiated to poorly differentiated, determined by PNA binding. Specimens showed morphological changes and a pronounced increase in PNA binding in Golgi apparatus, secretory granules of the cytosol of well differentiated and an increased cell membrane labeling in moderately and poorly differentiated, when compared with ESCC and normal tissues. Conclusion The authors propose that the expression of TF-antigen in human may play an important role during tumorigenesis establishing it as a chemically well-defined carcinoma-associated antigen. Identification of the circulating TF-antigen as a reactive form and as a cryptic form in the healthy individuals, using PNA-ELLA and Immunohistochemical analysis of TF antigen by FAT is positively correlated with the different histological grades as a simple

Second group –rats, which were introduced 0,05 ml solution of antigen in the amniotic fluid on the 18th day of pregnancy by the method of N. Voloshyn, the third group – control, the animals were introduced intrauterine 0,05 ml of physiological solution on the 18th day of pregnancy. The antigen was split vaccine Vaxigrip 2009. Results and conclusion. In newborn animals, after intrauterine antigen action it was determined significantly increased content of PNA+ lymphocytes in the epithelium of gingival mucous, compared with control group, where PNA+ lymphocytes number gradually decreases. On the 11 th day of life, in animals of second group, quantity of intraepithelial PNA+ lymphocytes remains higher. On 45th day of postnatal formation its share does not significantly differ from similar indicators in all groups and decreases compared with neonatal period. Citation: Burega Yu.

    Analogical reasoning is vital to advanced cognition and behavioral adaptation. Many theorists deem analogical thinking to be uniquely human and to be foundational to categorization, creative problem solving, and scientific discovery. Comparative psychologists have long been interested in the species generality of analogical reasoning, but they initially found it difficult to obtain empirical support for such thinking in nonhuman animals (for pioneering efforts, see [2, 3]). Researchers have since mustered considerable evidence and argument that relational matching-to-sample (RMTS) effectively captures the essence of analogy, in which the relevant logical arguments are presented visually. In RMTS, choice of test pair BB would be correct if the sample pair were AA, whereas choice of test pair EF would be correct if the sample pair were CD. Critically, no items in the correct test pair physically match items in the sample pair, thus demanding that only relational sameness or differentness is available to support accurate choice responding. Initial evidence suggested that only humans and apes can successfully learn RMTS with pairs of sample and test items; however, monkeys have subsequently done so. Here, we report that crows too exhibit relational matching behavior. Even more importantly, crows spontaneously display relational responding without ever having been trained on RMTS; they had only been trained on identity matching-to-sample (IMTS). Such robust and uninstructed relational matching behavior represents the most convincing evidence yet of analogical reasoning in a nonprimate species, as apes alone have spontaneously exhibited RMTS behavior after only IMTS training.

    In order to enhance the resistance to pests, transgenic maize (Zea mays L.) plants from elite inbred lines containing the gene encoding snowdrop lectin (Galanthus nivalis L. agglutinin; GNA) under control of a phloem-specific promoter were generated through the Agrobacterium tumefaciens-mediated also studied. Thirty-six independently derived plants were subjected to molecular analyses. The level of GNA expression at 0.13%-0.28% of total soluble protein was observed in different transgenic plants. The progeny of three GNA-expressing independent transformants that were derived separately from the elite inbred lines DH4866, DH9942, and 8902, were selected for examination of resistance to ACB. These plants synthesized GNA at levels above 0.24% total soluble protein and enhanced resistance to ACB was demonstrated by exposing the plants to insects under greenhouse conditions. Semi-artificial diet bioassays also showed the toxic effect of GNA on ACB. Field evaluation of the transgenic plants supported the results from the artificial trial. In the present study, we have obtained new insect-resistant maize material for further breeding work and have found that GNA-expressing plants not only gained significant resistance to homopterans, but also showed toxicity to ACB, which is a type of Lepidoptera.

    Papain-like cysteine proteases (PLCPs) constitute the largest group of thiol-based protein degrading enzymes and are characterized by a highly conserved fold. They are found in bacteria, viruses, plants and animals and involved in a number of physiological and pathological processes, parasitic infections and host defense, making them interesting targets for drug design. The Marasmius oreades agglutinin (MOA) is a blood group B-specific fungal chimerolectin with calcium-dependent proteolytic activity. The proteolytic domain of MOA presents a unique structural arrangement, yet mimicking the main structural elements in known PLCPs. Here we present the X-ray crystal structure of MOA in complex with Z-VAD-fmk, an irreversible caspase inhibitor known to cross-react with PLCPs. The structural data allow modeling of the substrate binding geometry and mapping of the fundamental enzyme-substrate interactions. The new information consolidates MOA as a new, yet strongly atypical member of the papain superfamily. The reported complex is the first published structure of a PLCP in complex with the well characterized caspase inhibitor Z-VAD-fmk. PMID:26901797

  9. In vivo toxicity and immunogenicity of wheat germ agglutinin conjugated poly(ethylene glycol)-poly(lactic acid) nanoparticles for intranasal delivery to the brain

    International Nuclear Information System (INIS)

    Biodegradable polymer-based nanoparticles have been widely studied to deliver therapeutic agents to the brain after intranasal administration. However, knowledge as to the side effects of nanoparticle delivery system to the brain is limited. The aim of this study was to investigate the in vivo toxicity and immunogenicity of wheat germ agglutinin (WGA) conjugated poly(ethylene glycol)-poly(lactic acid) nanoparticles (WGA-NP) after intranasal instillation. Sprague-Dawley rats were intranasally given WGA-NP for 7 continuous days. Amino acid neurotransmitters, lactate dehydrogenase (LDH) activity, reduced glutathione (GSH), acetylcholine, acetylcholinesterase activity, tumor necrosis factor α (TNF-α) and interleukin-8 (IL-8) in rat olfactory bulb (OB) and brain were measured to estimate the in vivo toxicity of WGA-NP. Balb/C mice were intranasally immunized by WGA-NP and then WGA-specific antibodies in serum and nasal wash were detected by indirect ELISA. WGA-NP showed slight toxicity to brain tissue, as evidenced by increased glutamate level in rat brain and enhanced LDH activity in rat OB. No significant changes in acetylcholine level, acetylcholinesterase activity, GSH level, TNF-α level and IL-8 level were observed in rat OB and brain for the WGA-NP group. WGA-specific antibodies in mice serum and nasal wash were not increased after two intranasal immunizations of WGA-NP. These results demonstrate that WGA-NP is a safe carrier system for intranasal delivery of therapeutic agents to the brain.

    International Nuclear Information System (INIS)

    The three-dimensional structure of the complex of agglutinin from Ricinus communis with β-D-galactose was established and refined at 2.5 A resolution by X-ray structure analysis. Biocrystals were obtained using dialysis through a semipermeable membrane. X-ray intensity data (Rmerge = 4.6%) were collected from one crystal at 100 K using synchrotron radiation at the DESY outstation [European Molecular Biology Laboratory (EMBL), Hamburg, Germany]. The initial phases were calculated by the molecular replacement method. The atoms of both protein and sugar molecules were localized. Unlike ricin, the ricinlike heterodimer RcA contains only one galactose-binding center in the region of the Asn46-Gly25-Trp37-Lys40 site in the first domain of the B subunit, whereas the second galactose-binding site of the B subunit is lost. One functionally important water molecule, which is bound to the residues Tyr123-Glu176-Arg179-Glu207, was revealed in the region of the active center in the A subunit

    Highlights: • A novel biosensor was developed for the detection of prostate cancer cells. • The selectivity of the biosensor was improved using antibody as capture probe. • The biosensor showed the low extremely detection limit of 2.6 × 10{sup 2} cells mL{sup −1}. • The ruthenium complex-labelled WGA can be transported in the cell vesicles. - Abstract: A highly selective and sensitive electrogenerated chemiluminescence (ECL) biosensor for the detection of prostate PC-3 cancer cells was designed using a prostate specific antibody as a capture probe and ruthenium complex-labelled wheat germ agglutinin as a signal probe. The ECL biosensor was fabricated by covalently immobilising the capture probe on a graphene oxide-coated glassy carbon electrode. Target PC-3 cells were selectively captured on the surface of the biosensor, and then, the signal probe was bound with the captured PC-3 cells to form a sandwich. In the presence of tripropylamine, the ECL intensity of the sandwich biosensor was logarithmically directly proportion to the concentration of PC-3 cells over a range from 7.0 × 10{sup 2} to 3.0 × 10{sup 4} cells mL{sup −1}, with a detection limit of 2.6 × 10{sup 2} cells mL{sup −1}. The ECL biosensor was also applied to detect prostate specific antigen with a detection limit of 0.1 ng mL{sup −1}. The high selectivity of the biosensor was demonstrated in comparison with that of a lectin-based biosensor. The strategy developed in this study may be a promising approach and could be extended to the design of ECL biosensors for highly sensitive and selective detection of other cancer-related cells or cancer biomarkers using different probes.

    The Streptococcus mutans antigen I/II (AgI/II) is a cell surface-localized protein that adheres to salivary components and extracellular matrix molecules. Here we report the 2.5 {angstrom} resolution crystal structure of the complete C-terminal region of AgI/II. The C-terminal region is comprised of three major domains: C{sub 1}, C{sub 2}, and C{sub 3}. Each domain adopts a DE-variant IgG fold, with two {beta}-sheets whose A and F strands are linked through an intramolecular isopeptide bond. The adherence of the C-terminal AgI/II fragments to the putative tooth surface receptor salivary agglutinin (SAG), as monitored by surface plasmon resonance, indicated that the minimal region of binding was contained within the first and second DE-variant-IgG domains (C{sub 1} and C{sub 2}) of the C terminus. The minimal C-terminal region that could inhibit S. mutans adherence to SAG was also confirmed to be within the C{sub 1} and C{sub 2} domains. Competition experiments demonstrated that the C- and N-terminal regions of AgI/II adhere to distinct sites on SAG. A cleft formed at the intersection between these C{sub 1} and C{sub 2} domains bound glucose molecules from the cryo-protectant solution, revealing a putative binding site for its highly glycosylated receptor SAG. Finally, electron microscopy images confirmed the elongated structure of AgI/II and enabled building a composite tertiary model that encompasses its two distinct binding regions.

  18. Science Fiction Exhibits as STEM Gateways

    Science.gov (United States)

    Robie, Samantha

    Women continue to hold less than a quarter of all STEM jobs in the United States, prompting many museums to develop programs and exhibits with the express goal of interesting young girls in scientific fields. At the same time, a number of recent museum exhibits have harnessed the popularity of pop culture and science fiction in order to interest general audiences in STEM subject matter, as well as using the exhibits as springboards to expand or shift mission goals and focus. Because science fiction appears to be successful at raising interest in STEM fields, it may be an effective way to garner the interest of young girls in STEM in particular. This research seeks to describe the ways in which museums are currently using science fiction exhibits to interest young girls in STEM fields and careers. Research focused on four institutions across the country hosting three separate exhibits, and included staff interviews and content analysis of exhibit descriptions, promotional materials, a summative evaluation and supplementary exhibit productions. In some ways, science fiction exhibits do serve young girls, primarily through the inclusion of female role models, staff awareness, and prototype testing to ensure interactives are attractive to girls as well as to boys. However, STEM appears to be underutilized, which may be partly due to a concern within the field that the outcome of targeting a specific gender could be construed as "stereotyping".

    2002-12-01

    The Space Science Institute (SSI) of Boulder, Colorado, has recently developed two museum exhibits called the Space Weather Center and MarsQuest. It is currently planning to develop a third exhibit called InterActive Earth. The Space Weather Center was developed in partnership with various research missions at NASA's Goddard Space Flight Center. The development of these exhibitions included a comprehensive evaluation plan. I will report on the important role evaluation plays in exhibit design and development using MarsQuest and InterActive Earth as models. The centerpiece of SSI's Mars Education Program is the 5,000-square-foot traveling exhibition, MarsQuest: Exploring the Red Planet, which was developed with support from the National Science Foundation (NSF), NASA, and several corporate donors. The MarsQuest exhibit is nearing the end of a highly successful, fully-booked three-year tour. The Institute plans to send an enhanced and updated MarsQuest on a second three-year tour and is also developing Destination: Mars, a mini-version of MarsQuest designed for smaller venues. They are designed to inspire and empower participants to extend the excitement and science content of the exhibitions into classrooms and museum-based education programs in an ongoing fashion. The centerpiece of the InterActive Earth project is a traveling exhibit that will cover about 4,000 square feet. The major goal of the proposed exhibit is to introduce students and the public to the complexity of the interconnections in the Earth system, and thereby, to inspire them to better understand planet Earth. Evaluation must be an integral part of the exhibition development process. For MarsQuest, a 3-phase evaluation (front end, formative and summative) was conducted by Randi Korn and Associates in close association with the development team. Sampling procedures for all three evaluation phases ensured the participation of all audiences, including family groups, students, and adults. Each phase of

The purpose of CERN's new mini-exhibition is to be more interactive and easier to install. Due to its size, the main travelling exhibition cannot be moved around quickly, which is why it stays in the same country for 4 to 6 months. But this means a long waiting list for the other Member States. To solve this problem, the Education Group has designed a new exhibition, which is smaller and thus easier to install. Smaller maybe, but no less rich in content, as the new exhibition conveys exactly the same messages as its larger counterpart. However, in the slimm...

    Telling the story of NASA-sponsored scientific research to the public in exhibits is best done by partnerships of scientists and museum professionals. Likewise, preparing classroom activities and training teachers to use them should be done by teams of teachers and scientists. Here we describe how we used such partnerships to develop a new astrobiology augmentation to the Microbes! traveling exhibit and a companion education module.

    It is critically important for the public to better understand the scientific process. Museum exhibitions are an important part of informal science education that can effectively reach public audiences as well as school groups. They provide an important gateway for the public to learn about compelling scientific endeavors. The Space Science Institute (SSI) is a national leader in producing traveling science exhibitions and their associated educational programming (i.e. interactive websites, educator workshops, public talks, instructional materials). The focus of this presentation will be on three of its exhibit projects: MarsQuest (currently on tour), Alien Earths (in fabrication), and Giant Planets (in development). MarsQuest is enabling millions of Americans to share in the excitement of the scientific exploration of Mars and to learn more about their own planet in the process. Alien Earths will bring origins-related research and discoveries to students and the American public. It has four interrelated exhibit areas: Our Place in Space, Star Birth, PlanetQuest, and Search for Life. Exhibit visitors will explore the awesome events surrounding the birth of stars and planets; they will join scientists in the hunt for planets outside our solar system including those that may be in "habitable zones" around other stars; and finally they will be able to learn about how scientists are looking for signs of life beyond Earth. Giant Planets: Exploring the Outer Solar System will take advantage of the excitement generated by the Cassini mission and bring planetary and origins research and discoveries to students and the public. It will be organized around four thematic areas: Our Solar System; Colossal Worlds; Moons, Rings, and Fields; and Make Space for Kids. Giant Planets will open in 2007. This talk will focus on the importance of making Earth comparisons in the conceptual design of each exhibit and will show several examples of how these comparisons were manifested in

  14. Curated exhibitions and Australian art history

    2011-06-01

    Full Text Available Australian Art history in all it guises has tended to bypass the impact of contemporary curated exhibitions on shaping the discipline. Yet an examination of a cluster of key contemporary exhibitions from the early 1970s onwards reveals their significance for the history of art in Australia. They reflect institutional judgements behind the selection, research and display the work of artists as well as the reception of such work by the public, artists, art critics and art historians. This is especially so in the last decades of the 20th century and the first decade of the 21st, as the country underwent major cultural changes. This paper focuses on selected exhibitions of Australian art from 1968 to 2008 and indicates how exhibitions also constitute a major form of contemporary Australian art historiography. As this period coincides with a transformation in the way exhibitions were funded, it also begins to investigate the question of the long term impact of public funding of the arts.

    The first CERN exhibition in Bulgaria attracted many visitors. In the first ever CERN exhibition to be held in Bulgaria, over 1,400 visitors, many of them students and young physicists, visited the 10-day event in Sofia. The CERN mini-exhibition took place at the National Earth and Mankind Museum between 8 and 17 November. Permanently staffed by young physicists from Sofia University, there were exhibits on display about research activities at CERN, as well as four additional posters describing Bulgaria's participation. The inauguration took place on the morning of 8 November in the presence of the Vice-Minister for Science and Education, Mrs. Vanya Dobreva, and some 200 guests. A series of short speeches were followed by a visit to the exhibition. CERN's representative at the event, Ray Lewis, was then asked by Professor Matey Mateev, President of the Union of Physicists in Bulgaria, to say a few words on behalf of the Organization. Numerous journalists were also present at the inauguration. A painting enti...

    Full Text Available Museum ethics are about value judgements. In making such judgements museum personnel is constantly valuing one option over another. This holds true for every aspect of museum work; from collecting policies and conservation to store priorities and exhibition. In recent decades there has been a growing concern in addressing ethical issues in museums as museum workers have developed cultural sensitivity and social responsiveness to a degree unseen before. Most codes of ethics urge museums to give appropriate consideration to represented groups or beliefs. In light of this, it has been recognised that exhibition of sensitive material, for example, must be done with great tact and respect for the feelings of religious, ethnic or other groups represented. Another issue concerns the display of unprovenanced material and repatriation. Yet, these are not the only ethical issues which exhibition developers are faced with. As museum workers we should constantly be reminded that exhibitions are active agents in the construction of knowledge. This paper discusses the hidden assumptions on which museum presentation and interpretation are often based. Decisions about what to include and what to exclude, what is valued and what is not, the means of presentation, language, and so on, all lead to presentational styles which may shape the public’s perception in unintended ways.

    Full text: The European Laboratory for Nuclear Research (CERN) and the H. Niewodniczanski Institute of Nuclear Physics together with the Institute of Physics of the Jagiellonian University and the University of Mining and Metallurgy, and under the auspices of the Polish National Atomic Energy Agency organized in the Museum of Nature in Cracow from October 16 till December 16, 2000 the exhibition ''When Energy Becomes Matter''. The Office of the ''Festival Cracow 2000'' was the main sponsor of that event. The exhibition was a part of the Festival Cracow 2000'' called ''Festival of Youngsters Cracow 2000''. Invitations, posters and information leaflets were sent to more than 3000 schools in southern Poland. The exhibition was divided into four specially designed quadrants. In the first the visitor was informed what kind of scales are in use to describe the Universe and the atom. The second introduced elementary particles via the cosmic ray demonstrations. Particle acceleration was demonstrated with the help of a TV set. The third segment was devoted to the Large Hadron Collider and its experiments: CMS, ATLAS, ALICE and LHCb. The last segment was an attempt to explain what are quarks, leptons and intermediate bosons. In addition it was also explained what is antimatter and why symmetry is broken in Nature. In one of the rooms we arranged the cinema where five movies was continuously presented. Thanks to the Cracow TV it was possible to prepare Polish translations of the films: Back to creation,Powers of ten,LHC - time machine,Stars underground, and Geneva event . Another attraction of the exhibition was the Internet room equipped with the help of Polish Telecommunication. The exhibition was open seven days per week from 10 to 17 h. During the working days every 20 minutes a new group of about 25-30 people was visiting the exhibition. Each group was guided by students and PhD students from our Institute, Jagiellonian University and University of Mining and Metallurgy

    2016-01-01

    The Internet is a man-made complex system under constant attacks (e.g., Advanced Persistent Threats and malwares). It is therefore important to understand the phenomena that can be induced by the interaction between cyber attacks and cyber defenses. In this paper, we explore the rich phenomena that can be exhibited when the defender employs active defense to combat cyber attacks. To the best of our knowledge, this is the first study that shows that {\\em active cyber defense dynamics} (or more generally, {\\em cybersecurity dynamics}) can exhibit the bifurcation and chaos phenomena. This has profound implications for cyber security measurement and prediction: (i) it is infeasible (or even impossible) to accurately measure and predict cyber security under certain circumstances; (ii) the defender must manipulate the dynamics to avoid such {\\em unmanageable situations} in real-life defense operations.

    Gebbensleben, Sandra; Dittmann, Jana; Vielhauer, Claus

    2006-02-01

    In our paper we introduce a new Audio Guide concept for exploring buildings, realms and exhibitions. Actual proposed solutions work in most cases with pre-defined devices, which users have to buy or borrow. These systems often go along with complex technical installations and require a great degree of user training for device handling. Furthermore, the activation of audio commentary related to the exhibition objects is typically based on additional components like infrared, radio frequency or GPS technology. Beside the necessity of installation of specific devices for user location, these approaches often only support automatic activation with no or limited user interaction. Therefore, elaboration of alternative concepts appears worthwhile. Motivated by these aspects, we introduce a new concept based on usage of the visitor's own mobile smart phone. The advantages in our approach are twofold: firstly the Audio Guide can be used in various places without any purchase and extensive installation of additional components in or around the exhibition object. Secondly, the visitors can experience the exhibition on individual tours only by uploading the Audio Guide at a single point of entry, the Audio Guide Service Counter, and keeping it on her or his personal device. Furthermore, since the user usually is quite familiar with the interface of her or his phone and can thus interact with the application device easily. Our technical concept makes use of two general ideas for location detection and activation. Firstly, we suggest an enhanced interactive number based activation by exploiting the visual capabilities of modern smart phones and secondly we outline an active digital audio watermarking approach, where information about objects are transmitted via an analog audio channel.

  1. Synchronization in multicell systems exhibiting dynamic plasticity

    Indian Academy of Sciences (India)

    C Suguna; Somdatta Sinha

    2008-08-01

    Collective behaviour in multicell systems arises from exchange of chemicals/signals between cells and may be different from their intrinsic behaviour. These chemicals are products of regulated networks of biochemical pathways that underlie cellular functions, and can exhibit a variety of dynamics arising from the non-linearity of the reaction processes. We have addressed the emergent synchronization properties of a ring of cells, diffusively coupled by the end product of an intracellular model biochemical pathway exhibiting non-robust birhythmic behaviour. The aim is to examine the role of intercellular interaction in stabilizing the non-robust dynamics in the emergent collective behaviour in the ring of cells. We show that, irrespective of the inherent frequencies of individual cells, depending on the coupling strength, the collective behaviour does synchronize to only one type of oscillations above a threshold number of cells. Using two perturbation analyses, we also show that this emergent synchronized dynamical state is fairly robust under external perturbations. Thus, the inherent plasticity in the oscillatory phenotypes in these model cells may get suppressed to exhibit collective dynamics of a single type in a multicell system, but environmental influences can sometimes expose this underlying plasticity in its collective dynamics.

  3. Bumblebees exhibit the memory spacing effect

    Science.gov (United States)

    Toda, Nicholas R. T.; Song, Jeremy; Nieh, James C.

    2009-10-01

    Associative learning is key to how bees recognize and return to rewarding floral resources. It thus plays a major role in pollinator floral constancy and plant gene flow. Honeybees are the primary model for pollinator associative learning, but bumblebees play an important ecological role in a wider range of habitats, and their associative learning abilities are less well understood. We assayed learning with the proboscis extension reflex (PER), using a novel method for restraining bees (capsules) designed to improve bumblebee learning. We present the first results demonstrating that bumblebees exhibit the memory spacing effect. They improve their associative learning of odor and nectar reward by exhibiting increased memory acquisition, a component of long-term memory formation, when the time interval between rewarding trials is increased. Bombus impatiens forager memory acquisition (average discrimination index values) improved by 129% and 65% at inter-trial intervals (ITI) of 5 and 3 min, respectively, as compared to an ITI of 1 min. Memory acquisition rate also increased with increasing ITI. Encapsulation significantly increases olfactory memory acquisition. Ten times more foragers exhibited at least one PER response during training in capsules as compared to traditional PER harnesses. Thus, a novel conditioning assay, encapsulation, enabled us to improve bumblebee-learning acquisition and demonstrate that spaced learning results in better memory consolidation. Such spaced learning likely plays a role in forming long-term memories of rewarding floral resources.

    Full Text Available As the inheritor of Chinese civilization, the National Palace Museum (hereafter referred to as the NPM, houses a world-class collection of cultural art and artifacts. Since the NPM began promoting the National Digital Archives Project in 2002, its efforts have expanded to develop a digital museum and various e-learning programs. Extending the use of digital archives to its educational and cultural industrial endeavors, the NPM has maximized the value of its exhibitions, publications, and educational programs.  In 2013, the NPM integrated creative thinking and interdisciplinary technologies, such as floating projection, augmented reality, and other sensory interactive media, to recreate the historical circumstance of 19th century East Asian maritime cultures in “Rebuilding the Tong-an Ships—New Media Art Exhibition," which opened at Huashan 1914 Creative Park and later won the Gold Award at the 2014 Digital Education Innovation Competition. Through a thorough exploration of the factors contributing to the success of "Rebuilding the Tong-an Ships," this study has isolated the two main factors of the exhibition’s popularity, namely, the compactness of the metadata and the atmosphere created by the interactive display technology.

    Full Text Available Annual archaeological exhibitions were a visible symbol of archaeological research. Held mainly in London, the displays encapsulated a network of archaeologists, artists, architects and curators, and showcased the work of the first generations of trained archaeologists. The exhibition catalogues and published reviews of the displays provide a unique method for exploring the reception and sponsorship of archaeological work overseas and its promotion to a fascinated, well connected and well moneyed public. The exhibitions were a space in which conversation and networking were as important as educational enrichment. This paper analyses the social history of the “annual exhibition” in archaeology, highlighting the development and maintenance of the networks behind archaeological research, the geography of London as a way to examine influence in archaeology, and the utility of exhibitions for archaeological publicity during this period of exploration.

  12. The Road Transport world exhibition in Paris

    International Nuclear Information System (INIS)

    Following the agreement between French and German professionals of automobile and industrial vehicle, the Road Transport world exhibition will take place alternatively in Paris and Hanover. The 1995 meeting has taken place in Paris (September 15-21) and about 20 countries were represented. Road transport is the principal way of goods transportation in France and represent 88% of the traffic explained in tons gross and 70% in tons km. The petroleum dependence of the transportation sector is becoming a worrying problem as the gasoline and diesel fuels taxes will be discussed in the 1996 financial laws project. According to the last ''Worldwide energetic perspectives'' report published by the IEA, in 2010 the transportation sector could absorb more than 60% of the worldwide petroleum consumption. This increase represents a challenge to the petroleum industry to increase the energetic efficiency of the vehicle fuels and the production of diesel fuels, and conversely to reduce the pollution effluents.

    Computationally based approaches are allowing to progress in the discovery and design of nano-scaled materials. Here we propose a series of new mono-layered compounds with exotic properties. By means of density functional theory calculations we demonstrate that the pentagonal arrangement of SiC2 yields an inverted distribution of the p-bands which leads to an unusual electronic behaviour of the material under strain [J. Phys. Chem. C, 2015, 119 (33), pp 19469]. A different pentagonal arrangement of C atoms enables the formation of Dirac cones which, unlike graphene, exhibit a strain-mediated tunable band gap.

    In the National Museum of Japanese History, 215,759 artifacts are stored and used for research and exhibitions. In museums, due to the limitation of space in the galleries, a guidance system is required to satisfy visitors' needs and to enhance their understanding of the artifacts. We introduce one exhibition using imaging technology to improve visitors' understanding of a kimono (traditional Japanese clothing) exhibition. In the imaging technology introduced, one data projector, one display with touch panel interface, and magnifiers were used as exhibition tools together with a real kimono. The validity of this exhibition method was confirmed by results from a visitors' interview survey. Second, to further develop the interactive guidance system, an augmented reality system that consisted of cooperation between the projector and a digital video camera was also examined. A white paper board in the observer's hand was used as a projection screen and also as an interface to control the images projected on the board. The basic performance of the proposed system was confirmed; however continuous development was necessary for applying the system to actual exhibitions.

    An exhibit of Cassini's images will open at NYC's American Museum of Natural History in March 2008 and then visit the Johnson Art Museum (Cornell) throughout fall 2008, including during next year's DPS. It is under consideration by several other venues in the States and overseas. The exhibit will feature 40-50 images, ranging from letter size to large posters, taken by remote-sensing instruments aboard Cassini and Huygens. Photos will be organized into a half-dozen thematic clusters (e.g., organized by celestial target or by physical process); a panel will introduce each grouping with individual images identified briefly. The Saturn system is a perfect vehicle to educate citizens about planetary science and origins. The images’ beauty should capture the public's attention, allowing us to then engage their curiosity about the relevant science. Among the Saturn system's broad suite of objects are Enceladus and Titan, two satellites of astrobiological interest; moreover, the rings display many processes active in other astrophysical disks. Several auxiliary ideas will be implemented. In Ithaca, we will project images at night against the museum's sand-colored exterior walls. A 10-12 minute musical composition has been commissioned from Roberto Sierra to open the show. We will encourage school children to participate in a human orrery circling the museum and will seek volunteers to participate in several Saturnalia. At Cornell we will involve the university and local communities, by taping their reactions to the images’ exquisite beauty as well as to their scientific content. Cassini will be the E/PO focus of next year's DPS meeting; those materials will be employed throughout the fall at New York schools and be available to travel with the show. We intend to work with NYC partners to offer teacher credits for associated weekend courses. We will produce classroom materials, including a DVD, for teacher use.

    Astronauts experience sensorimotor changes during spaceflight, particularly during G-transitions. Post flight sensorimotor changes include spatial disorientation, along with postural and gait instability that may degrade operational capabilities of the astronauts and endanger the crew. A sensorimotor countermeasure that mitigates these effects would improve crewmember safety and decrease risk. The goal of this research is to investigate the potential use of stochastic vestibular stimulation (SVS) as a technology to improve sensorimotor function. We hypothesize that low levels of SVS will improve sensorimotor perception through the phenomenon of stochastic resonance (SR), when the response of a nonlinear system to a weak input signal is enhanced by the application of a particular nonzero level of noise. This study aims to advance the development of SVS as a potential countermeasure by 1) demonstrating the exhibition of stochastic resonance in vestibular perception, a vital component of sensorimotor function, 2) investigating the repeatability of SR exhibition, and 3) determining the relative contribution of the semicircular canals (SCC) and otolith (OTO) organs to vestibular perceptual SR. A constant current stimulator was used to deliver bilateral bipolar SVS via electrodes placed on each of the mastoid processes, as previously done. Vestibular perceptual motion recognition thresholds were measured using a 6-degree of freedom MOOG platform and a 150 trial 3-down/1-up staircase procedure. In the first test session, we measured vestibular perceptual thresholds in upright roll-tilt at 0.2 Hz (SCC+OTO) with SVS ranging from 0-700 µA. In a second test session a week later, we re-measured roll-tilt thresholds with 0, optimal (from test session 1), and 1500 µA SVS levels. A subset of these subjects, plus naive subjects, participated in two additional test sessions in which we measured thresholds in supine roll-rotation at 0.2 Hz (SCC) and upright y-translation at 1 Hz

    During the last two decades, since digital technologies have become more sophisticated in acquiring real data and building faithful copies of them, their improvements have suggested interesting applications in the field of valorisation of Historical, Cultural and Artistic Heritage, with significant consequences in the share and widespread of knowledge. But although several technologies and methodologies for 3d digitization have recently been developed and improved, the lack of a standard procedure and the costs connected to their use still doesn't encourage the systematic digital acquisition of wide collections and heritage. The aim of this paper is to show the state of the art of a project whose aim is to provide a methodology and a procedure to create digital reproductions of artefacts for Institutions called to preserve, manage and enhance the fruition of archaeological finds inside museums or through digital exhibitions. Our project's aim is to find the most suitable procedure to digitally acquire archaeo logical artefacts that usually have small dimensions and have very complex and detailed surfaces. Within our methodology, particular attention has been paid to the use of widely shared and open-source visualization systems that enhance the involvement of the user by emphasizing three-dimensional characteristics of artefacts through virtual reality.

    Today's digital revolution leads to the increasing mobile device usage, which has changed people's life and work. However, the traditional static display and graphic version is unable to meet the requirements of the modern audience, which makes museums face the challenge in the distribution of knowledge. Meanwhile, the information storm produced by big data emerged a variety of new media, such as social media, Natural User Interface, Augmented Reality, and electronic publishing. This dizzying array of tools offered opportunities for museums all over the world to become more vibrant and accessible. Museums around the world have been constant changed and improved its presentation, which provides a valuable experience for us. The new Shanghai Natural History Museum has also applied information technology on exhibition, education, research and collection. But the change does not mean a complete subversion. Because the museum audience are di- verse, such as born in a different era, have different learning habits, museums need to control the change magnitude of display technology to meet the requirements of different audience.

  20. Rats exhibit reference-dependent choice behavior.

    Human preferences depend on whether a chosen outcome appears to be a loss or a gain compared with what had been expected, i.e., in comparison to a reference point. Because reference dependence has such a strong influence on human decision-making, it is important to uncover its origins, which will in turn help delineate the underlying mechanisms. It remains unknown whether rats use reference points in decision-making, and yet, the study of rats could help address the question of whether reference dependence is evolutionarily conserved among mammals and could provide a nonhuman animal model to investigate the neural mechanisms underlying this important cognitive process. The aim of the current study was to determine whether rats show reference-dependent choice behavior. We developed a novel paradigm by modifying the "T" maze by installing "pockets" to the left and right of the "T" stem that held reward pellets so rats would potentially develop reference values for each option prior to choice. We found that the rats were indeed sensitive to the way alternatives were presented. That is, they exhibited reference-dependent choice behavior by avoiding the choice option framed as a loss (e.g., having four reward pellets in the pocket, but receiving only one), at least under conditions with certain outcomes and clear differences between the reference and outcome quantities. Despite the small number of rats in this study, this species-level capacity suggests that reference dependence in general and loss aversion in particular may be conserved traits that evolved at or before the emergence of mammals.

  1. Development of Exhibit on Arctic Climate Change Called The Arctic: A Friend Acting Strangely Exhibition

    2006-04-01

    The exhibition, The Arctic: A Friend Acting Strangely, was developed at the Smithsonian Institution’s National Museum of Natural History (NMNH) as a part of the museum’s Forces of Change exhibit series on global change. It opened to the public in Spring 2006, in conjunction with another Forces of Change exhibit on the Earth’s atmosphere called Change Is in the Air. The exhibit was a 2000 square-foot presentation that explored the forces and consequences of the changing Arctic as documented by scientists and native residents alike. Native peoples of the Arctic have always lived with year-to-year fluctuations in weather and ice conditions. In recent decades, they have witnessed that the climate has become unpredictable, the land and sea unfamiliar. An elder in Arctic Canada recently described the weather as uggianaqtuq —an Inuit word that can suggest strange, unexpected behavior, sometimes described as that of “a friend acting strangely.” Scientists too have been documenting dramatic changes in the Arctic. Air temperatures have warmed over most—though not all—of the Arctic since the 1950s; Arctic precipitation may have increased by as much as 8%; seasonal melting of the Greenland Ice Sheet has increased on average by 16% since 1979; polar-orbiting satellites have measured a 15¬–20% decline in sea ice extent since the 1970s; aircraft reconnaissance and ship observations show a steady decrease in sea ice since the 1950s. In response to this warming, plant distributions have begun to shift and animals are changing their migration routes. Some of these changes may have beneficial effects while others may bring hardship or have costly implications. And, many scientists consider arctic change to be a ‘bell-weather’ for large-scale changes in other regions of the world. The exhibition included text, photos artifacts, hands-on interactives and other exhibitry that illustrated the changes being documented by indigenous people and scientists alike.

    Full Text Available Appreciation of exhibits in a museum can be equated to a virtual experience of lives in the contexts originally surrounding the exhibits. Here we focus on the importance of weight information, and hence tested whether experiencing a weight during museum exhibit appreciation affects the beholders’ satisfaction and recognition memory for the exhibits. An experiment was performed at a museum exhibiting skeletal preparations of animals. We used nine preparations and prepared four weight stimuli as weight cues in accordance with the actual weight of four of the preparations: Remaining five preparations was displayed without weight stimuli. In the cued condition, participants were asked to lift up the weight stimuli during their observation of the four exhibits. In the uncued condition, participants observed the exhibits without touching the weight stimuli. After observation of the exhibits, the participants responded to a questionnaire that measured their impressions of the exhibits and the museum, and performed a recognition test on the exhibits. Results showed that memory performance was better and viewing duration was longer with weight lifting instruction than without instruction. A factor analysis on the questionnaires revealed four factors (likeability, contentment, value, and quality. A path analysis showed indirect effects of viewing duration on memory performance and willingness-to-pay for the museum appreciation through the impression factors. Our findings provide insight into a new interactive exhibition that enables long appreciation producing positive effects on visitors’ impression, memory, and value estimation for exhibits.

  9. Expression of Vicia villosa agglutinin (VVA)-binding glycoprotein in primary breast cancer cells in relation to lymphatic metastasis: is atypical MUC1 bearing Tn antigen a receptor of VVA?

    Aberrant carbohydrate expression frequently occurs in breast cancer and may endow cells with metastatic potential. Here we first studied the relationship between expression of Vicia villosa agglutinin (lectin) (VVA)-binding carbohydrates and aggressive breast cancer. We then investigated the molecular characteristics of these glycoproteins and compared them with those of glycoproteins recognized by the mouse anti-Tn monoclonal antibody (MAb) HB-Tn1. Histochemical studies of samples from 322 cases of invasive ductal carcinoma demonstrated that VVA-binding carbohydrate expression correlated with tumor stage, lymphatic invasion, and lymph node metastasis (p=0.0385, p=0.0019, and p=0.0430. respectively). Western blotting analysis of frozen materials from 39 cases, under denaturing and reducing conditions, revealed that the major cancer cell-specific VVA-binding proteins were molecules of about 30, 33, and >200 kDa. Cases expressing the approximately 33 kDa molecule had significant lymphatic invasion more frequently than did cases not expressing this molecule (p=0.0076). Binding of VVA to the approximately 30 and approximately 33 kDa molecules was completely lost by preincubation of VVA with 1 mM Tn antigen (N-acetylgalactosamine alpha1-O-serine). The VVA-binding molecules appeared to react with VU-3C6 anti-MUC1 MAb. Expression of HB-Tn1 in breast cancer cells showed significant correlation with expression of VVA-binding carbohydrate(s) (p<0.0001) but HB-Tn1 reactivity was not clearly related to breast cancer aggressiveness. Because anti-Tn MAbs bound to Tn antigen clusters, we concluded that atypical MUC1 bearing the noncluster form of Tn antigen is implicated in aggressive growth of primary breast cancer cells, particularly in lymphatic metastasis.

    2009-01-01

    Exhibition performance should be evaluated from different perspectives of stakeholders. The benefits of each stakeholder can not be satisfied when evaluating the exhibition performance from a single perspective or. only evaluating the economic performance of the exhibition. In this paper, the stakeholders are defined on the basis of questionnaire investigation and classified by mathematical statistical method. According to the requirements of the stakeholders, the exhibition performance appraisal indicators are extracted and, simplified by factor analysis, which leads to the formation of a set of performance appraisal index system. It is an instructive attempt to work out the exhibition performance appraisal model from the perspective of stakeholders, which may provide theoretical foundation and practice instruction for exhibition performance appraisal in our country.

    Full Text Available Using exhibition for the final project in Sociolinguistic study is really interesting for Universitas Siswa Bangsa Internasional students, especially for 2011 English Department students. Exhibition becomes interesting because this is the new thing to conduct the final project for English Department students’ cohort 2011 at Universitas Siswa Bangsa Internasional. The lecturer divides the students into pairs and each pairs should master one content or topic in Sociolinguistic study.  The students will do the exhibition about the topic that they get in a pairs. The lecturer also gives the students rubric sheet to fill by the visitors. The exhibition will make the students prepare themselves well because they will face many questions about the content which will be delivered by them. Beside, this exhibition also maintains students’ fluency in speaking English because they will explain and answer the questions from visitors with English. This paper tries to focus on how exhibition examination can maintain students’ fluency in speaking English.

    Botelho, Agostinho; Morais, Ana M.

    2006-12-01

    In this study we investigate students' learning during their interaction with two exhibits at a science center. Specifically, we analyze both students' procedures when interacting with exhibits and their understanding of the scientific concepts presented therein. Bernstein's theory of pedagogic discourse (1990, 2000) provided the sociological foundation to assess the exhibit-student interaction and allowed analysis of the influence of the characteristics of students, exhibits, and interactions on students' learning. Eight students (ages 12ndash;13 years of age) with distinct sociological characteristics participated in the study. Several findings emerged from the results. First, the characteristics of the students, exhibits, and interactions appeared to influence student learning. Second, to most students, what they did interactively (procedures) seems not to have had any direct consequence on what they learned (concept understanding). Third, the data analysis suggest an important role for designers and teachers in overcoming the limitations of exhibit-student interaction.

    Recently, science museums have begun to review their educational purposes and redesign their pedagogies. At the most basic level, this entails accounting for the performance of individual exhibits, and indeed, in some cases, research indicates shortcomings in exhibit design: While often successful...... in prompting visitors to carry out intended actions, exhibits do not necessarily promote the intended interpretations of these actions among visitors. Here, the notion of praxeology from didactics research is suggested as a model to remedy this shortcoming. The suggested role of praxeology is twofold......: as a means to operationalize the link between exhibit features and visitor activities; and as a template to transform scientists’ practices in the research context into visitors’ activities in the exhibit context.

  18. Creating National Narrative: The Red Guard Art Exhibitions and the National Exhibitions in the Chinese Cultural Revolution 1966 - 1976

    Directory of Open Access Journals (Sweden)

    Winnie Tsang

    2014-06-01

    Full Text Available The artistic development in China experienced drastic changes during the Cultural Revolution from 1966 to 1976. Traditional Chinese art was denounced, whereas propaganda art became predominant in shaping the public’s loyalty towards the Communist Party and the country. Two major groups of art exhibitions emerged during the Revolution—the unofficial Red Guard art exhibitions organized by student activists in collaboration with local communes and art schools between 1966 and 1968, and the state-run national exhibitions from 1972 to 1975. These exhibitions were significant to this period because they were held frequently in the capital city Beijing and occasionally elsewhere, and through art they presented unique revolutionary beliefs to the Chinese people in a public setting. While the Red Guard art exhibitions and the national exhibitions certainly created different national narratives, I argue that the national exhibitions were in fact an attempt to revise the national narrative created by the Red Guard art exhibitions in order to re-establish a more utopian, consistent, and official national narrative. This paper unravels the intricate relationship between the two groups of exhibitions by comparing their exhibition venues, ideological focuses, work selection and quality editing. 

  19. CERN Industrials Exhibitions - Over 30 Years of Tradition

    CERN Multimedia

    2001-01-01

    Industrial exhibitions have been part of the CERN landscape for 33 years. At least once each year several companies from the same country come to CERN to present their products and services. Now, a new scheme of one-day visits is giving potential exhibitors at CERN a lighter option. The United Kingdom inaugurated the Industrial Exhibitions in 1968, and it wasn't till 1971 that other countries staged exhibitions at CERN. This photo was taken in 1969, at the second British exhibition, where 16 companies were present. Four years after joining CERN, Poland inaugurated its first exhibition at CERN in 1995 in the presence of the former Director-General Chris Llewellyn-Smith. Almost all the Member States have held industrial exhibitions at the Organization. May '68 wasn't only revolutionary in Paris. For the very first time, an industrial exhibition took place at CERN. Great Britain was first to come with eight companies and remains until this day the most devoted country to the programme with 17 exhibitions and ...

    Full Text Available Cold agglutinin disease (CAD with autoimmune haemolytic anemia is characterized by the production of harmful cold autoantibodies associated with increased red cell destruction during exposure to cold. The treatment of CAD is very difficult and a great effort is required to obtain therapeutic success. Cyclophosphamide is a potent immunosuppressive agent which is widely used in all bone marrow transplantation conditioning regimens for patients with acquired severe aplastic anemia. In this report, we describe the case of a coronary artery disease patient with severe CAD, but without lymphoproliferative disease, in which general measures and immunosuppressive therapies were adopted, there by avoiding blood transfusions.A doença por aglutininas a frio (CAD cursando com anemia hemolítica auto-imune (AHAI é decorrente da produção de autoanticorpos que reagem muito bem a baixas temperaturas, dirigidos contra hemácias autólogas. A habilidade desses anticorpos em destruir as hemácias encontra-se diretamente relacionada à sua capacidade em fixar complemento durante a exposição do paciente a baixas temperaturas. A AHAI por anticorpos frios pode ser idiopática - ausência de doença de base - ou secundária, geralmente associada a desordens linfoproliferativas de células B ou determinados processos infecciosos. A hemólise é intravascular, através de aglutininas da classe IgM, com teste direto da antiglobulina humana positivo para complemento. O tratamento da CAD é difícil, exigindo um esforço contínuo, necessário para se obter sucesso terapêutico. A ciclofosfamida é um agente imunossupressor potente, amplamente utilizado em transplantes de medula óssea, particularmente nos portadores de anemia aplástica.

  17. Determination of trace alkaline phosphatase by affinity adsorption solid substrate room temperature phosphorimetry based on wheat germ agglutinin labeled with 8-quinolineboronic acid phosphorescent molecular switch and prediction of diseases

    The 8-quinolineboronic acid phosphorescent molecular switch (abbreviated as PMS-8-QBA. Thereinto, 8-QBA is 8-quinolineboronic acid, and PMS is phosphorescent molecular switch) was found for the first time. PMS-8-QBA, which was in the "off" state, could only emit weak room temperature phosphorescence (RTP) on the acetyl cellulose membrane (ACM). However, PMS-8-QBA turned "on" automatically for its changed structure, causing that the RTP of 8-QBA in the system increased, after PMS-8-QBA-WGA (WGA is wheat germ agglutinin) was formed by reaction between -OH of PMS-8-QBA and -COOH of WGA. More interesting is that the -NH 2 of PMS-8-QBA-WGA could react with the -COOH of alkaline phosphatase (AP) to form the affinity adsorption (AA) product WGA-AP-WGA-8-QBA-PMS (containing -NH-CO- bond), which caused RTP of the system to greatly increase. Thus, affinity adsorption solid substrate room temperature phosphorimetry using PMS-8-QBA as labelling reagent (PMS-8-QBA-AA-SSRTP) for the determination of trace AP was established. The method had many advantages, such as high sensitivity (the detection limit (LD) was 2.5 zg spot -1. For sample volume of 0.40 μl spot -1, corresponding concentration was 6.2 × 10 -18 g ml -1), good selectivity (the allowed concentration of coexisting material was higher, when the relative error was ±5%), high accuracy (applied to detection of AP content in serum samples, the result was coincided with those obtained by enzyme-linked immunoassay), which was suitable for the detection of trace AP content in serum samples and the forecast of human diseases. Meanwhile, the mechanism of PMS-8-QBA-AASSRTP was discussed. The new field of analytical application and clinic diagnosis technique of molecule switch are exploited, based on the phosphorescence characteristic of PMS-8-QBA, the AA reaction between WGA and AP, as well as the relation between AP content and human diseases. The research results promote the development and interpenetrate among molecule

  7. Science, providence, and progress at the Great Exhibition.

    Science.gov (United States)

    Cantor, Geoffrey

    2012-09-01

    The Great Exhibition of 1851 is generally interpreted as a thoroughly secular event that celebrated progress in science, technology, and industry. In contrast to this perception, however, the exhibition was viewed by many contemporaries as a religious event of considerable importance. Although some religious commentators were highly critical of the exhibition and condemned the display of artifacts in the Crystal Palace as giving succor to materialism, others incorporated science and technology into their religious frameworks. Drawing on sermons, tracts, and the religious periodical press, this essay pays close attention to the ways in which science and technology were endowed with providentialist significance and particularly examines the notion of human progress used by a number of Christian writers, especially Congregationalists, who set scientific and technological progress within a teleological religious perspective. This discussion sheds fresh light not only on the Great Exhibition itself but also on the deployment of natural theology in mid-nineteenth-century Britain. PMID:23286186

Sponsors indirect impact refers to implicit demands, where the staff members need to take into account what they believe are views of the sponsors through self-censorship. This means that staff members seem to need to take into account sponsors’ possible views and demands......Science and technology centres (STC) and science museums tend increasingly to rely on external economic support in order to create new exhibitions. But in what ways may the economic situation affect what is presented in their exhibitions? This article aims to explore how staff members consider the...... impact of sponsors when planning and creating new exhibitions. The results reveal that sponsors often are crucial, but also that sponsors may interfere with the content and design both directly and indirectly. Direct impact refers to sponsors’ explicit demands of being visible in the exhibition or...

  14. Ballroom Music Spillover into a Beluga Whale Aquarium Exhibit

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available It is not uncommon for modern aquaria to be built with special entertainment areas. There are no known measurements of sound spillover from such entertainment areas into underwater animal exhibits. Entertainment organizations typically prefer to play music for events at 95 and 100 dBA in a ballroom at Georgia Aquarium. Concern over the potential effects of the music and noise on animals in adjacent exhibits inspired an initial project to monitor and compare sound levels in the adjacent underwater exhibits against the typical in-air sound levels of the ballroom. Measured underwater noise levels were compared to modeled levels based on finite element analysis and plane wave transmission loss calculations through the acrylic viewing window. Results were compared with the model to determine how, if at all, the ambient noise level in the Cold Water Quest exhibit changed as a result of music played in the ballroom.

  6. A phenomenological investigation of science center exhibition developers' expertise development

    Science.gov (United States)

    Young, Denise L.

    The purpose of this study was to examine the exhibition developer role in the context of United States (U.S.) science centers, and more specifically, to investigate the way science center exhibition developers build their professional expertise. This research investigated how successfully practicing exhibition developers described their current practices, how they learned to be exhibition developers, and what factors were the most important to the developers in building their professional expertise. Qualitative data was gathered from 10 currently practicing exhibition developers from three science centers: the Exploratorium, San Francisco, California; the Field Museum, Chicago, Illinois; and the Science Museum of Minnesota, St. Paul, Minnesota. In-depth, semistructured interviews were used to collect the data. The study embraced aspects of the phenomenological tradition and sought to derive a holistic understanding of the position and how expertise was built for it. The data were methodically coded and organized into themes prior to analysis. The data analysis found that the position consisted of numerous and varied activities, but the developers' primary roles were advocating for the visitor, storytelling, and mediating information and ideas. They conducted these activities in the context of a team and relied on an established exhibition planning process to guide their work. Developers described a process of learning exhibition development that was experiential in nature. Learning through daily practice was key, though they also consulted with mentors and relied on visitor studies to gauge the effectiveness of their work. They were adept at integrating prior knowledge gained from many aspects of their lives into their practice. The developers described several internal factors that contributed to their expertise development including the desire to help others, a natural curiosity about the world, a commitment to learning, and the ability to accept critique. They

    2012-01-01

    How can you make a topic as abstract as black holes seem relevant to the life of the average museum visitor? In 2009, the Harvard-Smithsonian Center for Astrophysics developed a 2500 square foot interactive museum exhibition, "Black Holes: Space Warps & Time Twists,” with funding from the National Science Foundation and NASA. The exhibition has been visited by more than a quarter million museum-goers, and is about to open in its sixth venue at the Reuben H. Fleet Science Center in San Diego, California. We have found that encouraging visitors to adopt a custom black hole explorer's identity can help to make the science of black holes more accessible and meaningful. The Black Holes exhibition uses networked exhibit technology that serves to personalize the visitor experience, to support learning over time including beyond the gallery, and to provide a rich quantitative source of embedded evaluation data. Visitors entering the exhibition create their own bar-coded "Black Holes Explorer's Card” which they use throughout the exhibition to collect and record images, movies, their own predictions and conclusions, and other black hole artifacts. This digital database of personal discoveries grows as visitors navigate through the gallery, and an automated web-content authoring system creates a personalized online journal of their experience that they can access once they get home. We report here on new intriguing results gathered from data generated by 112,000 visitors across five different venues. For example, an initial review of the data reveals correlations between visitors’ black hole explorer identity choices and their engagement with the exhibition. We will also discuss correlations between learning gains and personalization.

    2016-01-01

    This paper explores how four design principles (curiosity, challenge, narratives and participation) facilitate reflection and discussion among young visitors in the issues-based exhibition Dear, Difficult Body. The investigation is based on a mixed-method approach combining questionnaire and...... interview data. The implementation of design principles resulted in a variety of exhibits which variously prompted reflection and discussion on the part of visitors. Exhibits with narratives, for example, here defined as both personal and expert narratives, were found to be effective in facilitating...... pupils’ attention but also worked well with other design principles to engage the pupils in sustained reflection and discussion. While other contextual factors remain significant in determining visitor responses, this paper argues that the use of design principles can help create visitor experiences that...

    2015-04-01

    How effective is visual communication to increase awareness of natural hazards and risks? To answer this research question, we developed a research design that was at the same time an experimental setting and an actual communication effort. Throughout the full length of the 2-years project held in the Ubaye valley (southeastern France), we collaborated with local and regional stakeholders (politicians and technicians). During a consultation phase, the communication context was determined, the audience of the project was defined and finally the testing activity-communication effort was determined. We were offered the opportunity to design an exhibition for the local public library. In a consultation phase that corresponded to the design of the exhibition, the stakeholders contributed to its content as well as helping with the funding of the exhibition. Finally, during the experimentation phase, the stakeholders participated in advertising the activity, gathering of participants and designing the scientific survey. In order to assess the effects of the exhibition on risk awareness, several groups of children, teenagers and adults were submitted to a research design, consisting of 1) a pre-test, 2) the visit of the exhibition and 3) a post-test similar to the pre-test. In addition, the children answered a second post-test 3 months after the visit. Close ended questions addressed the awareness indicators mentioned in the literature, i.e. worry level, previous experiences with natural hazards events, exposure to awareness raising, ability to mitigate/respond/prepare, attitude to risk, and demographics. In addition, the post-test included several satisfaction questions concerning the visual tools displayed in the exhibition. A statistical analysis of the changes between the pre- and post- tests (paired t-test, Wilcoxon signed-rank test and bootstrapping) allowed to verify whether the exhibition had an impact on risk awareness or not. In order to deduce which variable

    Analysis of embryonic fibroblasts from GFP reporter mice indicates that the fibroblast cell type harbors a large collection of developmentally and phenotypically heterogeneous subtypes. Some of these cells exhibit multipotency, whereas others do not. Multiparameter flow cytometry analysis shows that a large number of distinct populations of fibroblast-like cells can be found in cultures initiated from different embryonic organs, and cells sorted according to their surface phenotype typically retain their characteristics on continued propagation in culture. Similarly, surface phenotypes of individual cloned fibroblast-like cells exhibit significant variation. The fibroblast cell class appears to contain a very large number of denumerable subtypes.

    2013-10-01

    We present a framework, called TrayGen, to generate tray designs for the exhibition and packaging of a collection of objects. Based on principles from shape perception and visual merchandising, we abstract a number of design guidelines on how to organize the objects on the tray for the exhibition of their individual features and mutual relationships. Our framework realizes these guidelines by analyzing geometric shapes of the objects and optimizing their arrangement. We demonstrate that the resultant tray designs not only save space, but also highlight the characteristic of each object and the inter-relations between objects. © 2013 The Eurographics Association and John Wiley & Sons Ltd.

    Rice production is severely hampered by insect pests. Garlic lectin gene (ASAL) holds great promise in conferring protection against chewing (lepidopteran) and sap-sucking (homopteran) insect pests. We have developed transgenic rice lines resistant to sap-sucking brown hopper (Nilaparvata lugens) by ectopic expression of ASAL in their phloem tissues. Molecular analyses of T0 lines confirmed stable integration of transgene. T1 lines (NP 1-2, 4-3, 11-6 & 17-7) showed active transcription and translation of ASAL transgene. ELISA revealed ASAL expression was as high as 0.95% of total soluble protein. Insect bioassays on T2 homozygous lines (NP 18 & 32) revealed significant reduction (~74-83%) in survival rate, development and fecundity of brown hoppers in comparison to wild type. Transgenics exhibited enhanced resistance (1-2 score) against brown hoppers, minimal plant damage and no growth penalty or phenotypic abnormalities. PMID:24563293

    Science.gov (United States)

    Filipová, Marta

    2011-01-01

    In the increasingly modernized Central Europe of the late nineteenth century, folk culture, with its alleged ancient character, was still understood by some scholars as the bearer of national identity. The Czechoslavic [sic] Ethnographic Exhibition, which took place in Prague in 1895, aimed to promote the idea of the ethnically unified, but at the same time regionally diverse, identity of the Czech-speaking people living in Bohemia, Moravia and Slovakia. Having to negotiate their identity with the ethnic Germans of Bohemia, the Czechs consciously excluded them from the event both as organizers and as exhibitors. The exhibition could therefore be seen as a symptom of its time—in the late nineteenth century Central Europe, locating national heritage was crucial and folk culture played an important role in the national politics, and not only for the Czechs. This article focuses mainly on the ethnographic exhibit entitled ‘the Exhibition Village’, which consisted of an eclectic selection of village houses and their imitations from Bohemia, Moravia and Slovakia. On this basis, it explores the political intentions behind the display of folk culture to both urban and rural audiences and brings attention to the question of integration of the diverse regional objects in a utopian national whole. The article thus also aims to demonstrate issues related to the use of folk artefacts for the purposes of cultural nationalism in Austria-Hungary in the late nineteenth century. PMID:21574287

  20. 'Exhibitions and experiments', in celebration of nobel prize in physics

    International Nuclear Information System (INIS)

    The Nobel Prize in Physics for 2008 was awarded to Professors Yoichiro Nambu, Makoto Kobayashi and Toshihide Maskawa. At this opportunity, we held an exhibition to introduce the achievements of the laureates for 10 days at the Omiya campus in May 2009. With the explanations of elementary particle physics, we prepared several experimental instruments with which visitors could play and learn the spontaneous symmetry breaking, cosmic rays, a circle path of an electron in a magnetic field and so on. Our main purpose of the exhibition was, however, not just to explain the contents of the Nobel Prize in Physics, but also to attract students' interests to physics. More than 800 individual students attended during the period, and the survey of questionnaires shows positive contributions to raise the students' awareness of the excitement of physics. (author)

  1. Explosion of strange attractors exhibited by Duffing's equation

    International Nuclear Information System (INIS)

    Recently chaotic behavior in deterministic systems attracts attention of researchers in various fields. By using analog and digital computers, the author has long been engaged himself in the investigation on this kind of motion exhibited by Duffing's equation and has called the phenomenon the chaotically transitional process. The chaotically transitional process is attributed to both the small uncertain factors in the physical system and the global structure of the solutions of the equation. This paper also deals with chaotically transitional processes exhibited by Duffing's equation. The results obtained in the series of our reports and the unsolved problems developed from them are summarized. Special attention is directed towards the transition of the processes under the variation of the system parameter. The explosion of the strange attractor, i.e., an interesting type of transition from strange to strange attractor has been made clear. (author)

  8. Uranium mining wastes, garden exhibition and health risks

    International Nuclear Information System (INIS)

    Available in abstract form only. Full text of publication follows: For more than 40 years the Soviet-German stockholding company SDAG WISMUT mined and milled Uranium in the East of Germany and became up to 1990 the world's third largest Uranium producer. After reunification of Germany, the new found state own company Wismut GmbH was faced with the task of decommissioning and rehabilitation of the mining and milling sites. One of the largest mining areas in the world, that had to be cleaned up, was located close to the municipality of Ronneburg near the City of Gera in Thuringia. After closing the operations of the Ronneburg underground mine and at the 160 m deep open pit mine with a free volume of 84 Mio.m3, the open pit and 7 large piles of mine waste, together 112 Mio.m3 of material, had to be cleaned up. As a result of an optimisation procedure it was chosen to relocate the waste rock piles back into the open pit. After taking this decision and approval of the plan the disposal operation was started. Even though the transport task was done by large trucks, this took 16 years. The work will be finished in 2007, a cover consisting of 40 cm of uncontaminated material will be placed on top of the material, and the re-vegetation of the former open pit area will be established. When in 2002 the City of Gera applied to host the largest garden exhibition in Germany, Bundesgartenschau (BUGA), in 2007, Wismut GmbH supported this plan by offering parts of the territory of the former mining site as an exhibition ground. Finally, it was decided by the BUGA organizers to arrange its 2007 exhibition on grounds in Gera and in the valley adjacent to the former open pit mine, with parts of the remediated area within the fence of the exhibition.

    Plant phytochromes are photoreceptors that mediate a variety of photomorphogenic responses. There are two spectral photoisomers, the red light-absorbing Pr and far-red light-absorbing Pfr forms, and the photoreversible transformation between the two forms is important for the functioning of phytochromes. In this study, we isolated a Tyr-268-to-Val mutant of Avena sativa phytochrome A (AsYVA) that displayed little photoconversion. Interestingly, transgenic plants of AsYVA showed light-independent phytochrome signaling with a constitutive photomorphogenic (cop) phenotype that is characterized by shortened hypocotyls and open cotyledons in the dark. In addition, the corresponding Tyr-303-to-Val mutant of Arabidopsis (Arabidopsis thaliana) phytochrome B (AtYVB) exhibited nuclear localization and interaction with phytochrome-interacting factor 3 (PIF3) independently of light, conferring a constitutive photomorphogenic development to its transgenic plants, which is comparable to the first constitutively active version of phytochrome B (YHB; Tyr-276-to-His mutant). We also found that chromophore ligation was required for the light-independent interaction of AtYVB with PIF3. Moreover, we demonstrated that AtYVB did not exhibit phytochrome B activity when it was localized in the cytosol by fusion with the nuclear export signal and that AsYVA exhibited the full activity of phytochrome A when localized in the nucleus by fusion with the nuclear localization signal. Furthermore, the corresponding Tyr-269-to-Val mutant of Arabidopsis phytochrome A (AtYVA) exhibited similar cop phenotypes in transgenic plants to AsYVA. Collectively, these results suggest that the conserved Tyr residues in the chromophore-binding pocket play an important role during the Pr-to-Pfr photoconversion of phytochromes, providing new constitutively active alleles of phytochromes by the Tyr-to-Val mutation.

    Our Institute of Physics exposes since 1980 didactical exhibitions of holography in Brazil where nice holograms are shown altogether with basic experiments of geometric and wave optics. This experiments lead to the understanding of the phenomenon of images of an ample way. Thousands of people have been present at them, in their majority of the Universidade Estadual de Campinas, where since 2002 they have taken the format of a course without formal evaluation. This way the exhibition has been divided in four modules, in each one of them are shown different holograms, experiments of optics and applications of diffractive images with white light developed in the Institute of Physics. The sequence of the learning through the modules begins with the geometric optics, later we explain the wave optics and finally holography. The phenomenon of the diffraction in daily elements is shown experimentally from the beginning. As well as the application of the holographic screens in white light: the television images that appear in front of the screen and the spectator can try to experience the reality illusion. Put something so exclusive (that only exists in the laboratory) to the public is a way to approximate the persons to an investigation in course. The vision of images that seem to be of holograms, but in movement, and size of until a square meter completes this exhibition of an exclusive way in the world.

    Based on the theory of transformation optics, a type of homogeneous illusion device exhibiting transformed and shifted scattering effect is proposed in this paper. The constitutive parameters of the proposed device are derived, and full-wave simulations are performed to validate the electromagnetic properties of transformed and shifted scattering effect. The simulation results show that the proposed device not only can visually shift the image of target in two dimensions, but also can visually transform the shape of target. It is expected that such homogeneous illusion device could possess potential applications in military camouflage and other field of electromagnetic engineering.

  17. Thermoluminescence dating of materials which exhibit anomalous fading

    International Nuclear Information System (INIS)

    This article reports a generalised and systematic approach to the thermoluminescence (TL) dating of samples which suffer from anomalous fading. We hypothesise that the TL signal from each mineral phase is composed of a stable and an unstable portion. The decay of the unstable TL is accelerated thermally, until only stable TL remains. The dating is then carried out on this stable signal. The results, on four known-age, coeval samples, exhibiting gross anomalous fading (25 -50% loss over a few days), indicate that many, if not all, samples may successfully be dated with this approach.

    Goldstone, Robert L.; Helbing, Dirk

    2016-01-01

    To investigate the effect of competitive incentives under peer review, we designed a novel experimental setup called the Art Exhibition Game. We present experimental evidence of how competition introduces both positive and negative effects when creative artifacts are evaluated and selected by peer review. Competition proved to be a double-edged sword: on the one hand, it fosters innovation and product diversity, but on the other hand, it also leads to more unfair reviews and to a lower level of agreement between reviewers. Moreover, an external validation of the quality of peer reviews during the laboratory experiment, based on 23,627 online evaluations on Amazon Mechanical Turk, shows that competition does not significantly increase the level of creativity. Furthermore, the higher rejection rate under competitive conditions does not improve the average quality of published contributions, because more high-quality work is also rejected. Overall, our results could explain why many ground-breaking studies in science end up in lower-tier journals. Differences and similarities between the Art Exhibition Game and scholarly peer review are discussed and the implications for the design of new incentive systems for scientists are explained.

  1. Nanocomposite thin films exhibiting high mechanical and optical flexibility

    Science.gov (United States)

    2008-08-01

    Nanocomposites are created by doping host polymers with nanoparticles that typically have higher or lower refractive indices. The ability to tailor the mechanical and optical performance of these composites has led to their increased use in transparent materials. Nanocomposites maintain the elastic properties of the binding polymers and exhibit infinite refractive index tunability between the limits of the system. These unique properties provide distinct benefits for multilayer, thin-film optical filters. Because the nanoparticles are dispersed in a fluid or bound in a polymer matrix in use, toxicity risks that may be associated with raw particles are reduced. Using a stable dispersion of titanium dioxide nanoparticles and a UV curable monomer, we were able to design and produce several quarter-wave filters that demonstrate control of the height and width of the passband through adjustment of the organic/inorganic ratio and layer count. The volume loading of the metal oxides can be adjusted from zero to near the theoretical packing density of spheres, allowing refractive index to be controlled over a large range. Because metal oxide particles exhibit high UV absorption, these additives provide UV protection to the host polymer and the filter's substrate. Additionally, significant improvements in abrasion resistance are often observed in films loaded with nanoparticles at the concentrations of interest.

  5. Chimpanzees and bonobos exhibit emotional responses to decision outcomes.

    Directory of Open Access Journals (Sweden)

    Alexandra G Rosati

    Full Text Available The interface between cognition, emotion, and motivation is thought to be of central importance in understanding complex cognitive functions such as decision-making and executive control in humans. Although nonhuman apes have complex repertoires of emotional expression, little is known about the role of affective processes in ape decision-making. To illuminate the evolutionary origins of human-like patterns of choice, we investigated decision-making in humans' closest phylogenetic relatives, chimpanzees (Pan troglodytes and bonobos (Pan paniscus. In two studies, we examined these species' temporal and risk preferences, and assessed whether apes show emotional and motivational responses in decision-making contexts. We find that (1 chimpanzees are more patient and more risk-prone than are bonobos, (2 both species exhibit affective and motivational responses following the outcomes of their decisions, and (3 some emotional and motivational responses map onto species-level and individual-differences in decision-making. These results indicate that apes do exhibit emotional responses to decision-making, like humans. We explore the hypothesis that affective and motivational biases may underlie the psychological mechanisms supporting value-based preferences in these species.

    Chang and Eng, the two young men who would eventually be known around the world as the 'original' Siamese twins, arrived in the West in 1829. They were brought to the West to be examined by medical men and to be exhibited to the general public. Throughout the 19th century in Britain and the US, 'monstrosities' such as Chang and Eng, as well as a host of other people with unusual anatomies, were considered both spectacles worthy of public display and edifying medical subjects with the potential to build on medical knowledge. The unique case of Chang and Eng illustrates that the boundary between what is of legitimate medical interest and what is considered merely spectacle is often blurred. PMID:14652037

    Spinal muscular atrophy (SMA) presents severe muscle weakness with limited motor neuron (MN) loss at an early stage, suggesting potential functional alterations in MNs that contribute to SMA symptom presentation. Using SMA induced pluripotent stem cells (iPSCs), we found that SMA MNs displayed hyperexcitability with increased membrane input resistance, hyperpolarized threshold, and larger action potential amplitude, which was mimicked by knocking down full length survival motor neuron (SMN) in non-SMA MNs. We further discovered that SMA MNs exhibit enhanced sodium channel activities with increased current amplitude and facilitated recovery, which was corrected by restoration of SMN1 in SMA MNs. Together we propose that SMN reduction results in MN hyperexcitability and impaired neurotransmission, the latter of which exacerbate each other via a feedback loop, thus contributing to severe symptoms at an early stage of SMA.

  9. Development of constitutive model for composites exhibiting time dependent properties

    International Nuclear Information System (INIS)

    Regenerated cellulose fibres and their composites exhibit highly nonlinear behaviour. The mechanical response of these materials can be successfully described by the model developed by Schapery for time-dependent materials. However, this model requires input parameters that are experimentally determined via large number of time-consuming tests on the studied composite material. If, for example, the volume fraction of fibres is changed we have a different material and new series of experiments on this new material are required. Therefore the ultimate objective of our studies is to develop model which determines the composite behaviour based on behaviour of constituents of the composite. This paper gives an overview of problems and difficulties, associated with development, implementation and verification of such model

    The study investigates the effects of aqueous extract of Bougainvillea spectabilis leaves on blood glucose, glycosylated hemoglobin, lipid profile, oxidative stress, and on DNA damage, if any, as well as on liver and kidney functions in streptozotocin-induced diabetes in Wistar rats. Daily administration of the aqueous extract of B spectabilis leaves for 28 days resulted in significant reduction in hyperglycemia and hyperlipidemia as evident from restoration of relevant biochemical markers following extract administration. The extract also exhibited significant antioxidant activity as evidenced from the enzymatic and nonenzymatic responses and DNA damage markers. The extract restored kidney and liver functions to normal and proved to be nontoxic. A marked improvement in the histological changes of tissues was also observed. The present study documented antihyperglycemic, antihyperlipidemic, and antioxidative potentials of the aqueous extract of B spectabilis leaves without any toxicity in streptozotocin-treated Wistar rats.

    2002-01-01

    Infrared radiant powder was synthesized by conventional ceramic processing techniques by using Fe2O3, MnO2, CuO, Co2O3 and kaolin as raw materials. A novel infrared radiant glaze was developed by introducing the infrared radiant powder into glazing as a functional additive. Infrared radiant characteristics of the powder and the glaze were investigated. The optimum content of infrared radiant powder in glazing was ascertained to be 5%. The infrared radiant glaze exhibits significant antibacterial and antifungal functions due to the thermal effect of infrared radiation. Antibacterial percentages of the glaze reach 91%-100% when Escherichia coli, Staphylococcus aureus and Bacillus subtilis are used as model bacterium respectively, while antifungal percentage of the glaze exceeds 95% when Penicillum citrinum is used as model fungus.

    The yam (Dioscorea batatas Decne) tuber mucilage (YTM) was extracted and partially purified by SDS and heating treatments. This purified YTM exhibited antioxidant activities in a series of in vitro tests, including 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical (half-inhibition concentration, IC 50, was 0.86 mg/mL) and hydroxyl radical (IC 50 was 22 microg/mL) scavenging activity assays, reducing power test, anti-lipid peroxidation and anti-human low density lipoprotein peroxidation tests (IC 50 was 145.46 microg/mL) using butylated hydroxytoluene (BHT), reduced glutathione, or ascorbic acid for comparisons. With electron paramagnetic resonance (EPR) spectrometry for DPPH radical detection, the intensities of the EPR signals were decreased by the increased amounts of YTM added (IC 50 was 1.62 mg/mL). These results suggest that mucilage of yam tuber might play roles as antiradicals and antioxidants. PMID:12494332

  14. The Pahrump Valley Museum Yucca Mountain History Exhibit - 12389

    International Nuclear Information System (INIS)

    As part of its management of the Yucca Mountain project, the Department of Energy maintained several information centers to provide public access to information about the status of the Yucca Mountain project. Those information centers contained numerous displays, historical information, and served as the location for the Department's outreach activities. As the Department of Energy dealt with reduced budgets in 2009 following the Obama Administration's intent to terminate the program, it shut down its information centers. Nye County considered it important to maintain a public information center where people would be able to find information about what was happening with the Yucca Mountain project. Initially the Nye County assumed responsibility for the information center in Pahrump; eventually the County made a decision to move that information center into an expansion of the existing Pahrump Valley Museum. Nye County undertook an effort to update the information about the Yucca Mountain project and modernize the displays. A parallel effort to create a source of historical information where people could find out about the Yucca Mountain project was undertaken. To accompany the Yucca Mountain exhibits in the Pahrump Valley Museum, Nye County also sponsored a series of interviews to document, through oral histories, as much information about the Yucca Mountain project as could be found in these interviews. The paper presents an overview of the Yucca Mountain exhibits in the Pahrump Valley Museum, and the accompanying oral histories. An important conclusion that can be drawn from the interviews is that construction of a repository in Nevada should have been conceptualized as but the first step in transforming the economy of central Nevada by turning part of the Nevada National Security Site and adjoining area into a world-class energy production and energy research center.

Although effective, these treatment strategies are expensive and have several side effects. To improve drug efficiency, we tested liposomal nanoparticles as carrier systems. In this study, we synthesized liposomal nanoparticles tailored for the prostacyclin analogue iloprost and evaluated their pharmacologic efficacy on mouse intrapulmonary arteries, using a wire myograph. The use of cationic lipids, stearylamine, or 1,2-di-(9Z-octadecenoyl-3-trimethylammonium-propane (DOTAP in liposomes promoted iloprost encapsulation to at least 50%. The addition of cholesterol modestly reduced iloprost encapsulation. The liposomal nanoparticle formulations were tested for toxicity and pharmacologic efficacy in vivo and ex vivo, respectively. The liposomes did not affect the viability of human pulmonary artery smooth muscle cells. Compared with an equivalent concentration of free iloprost, four out of the six polymer-coated liposomal formulations exhibited significantly enhanced vasodilation of mouse pulmonary arteries. Iloprost that was encapsulated in liposomes containing the polymer polyethylene glycol exhibited concentration-dependent relaxation of arteries. Strikingly, half the concentration of iloprost in liposomes elicited

    Creating a natural disaster-ready community requires interoperating scientific, technical, and social systems. In addition to the technical elements that need to be in place, communities and individuals need to be prepared to react when a natural hazard event occurs. Natural hazard awareness and preparedness training and education often takes place through informal learning at science centers and formal k-12 education programs as well as through awareness raising via strategically placed informational tsunami warning signs and placards. Museums and science centers are influential in raising science literacy within a community, however can science centers enhance earthquake and tsunami resiliency by providing hazard science content and preparedness exhibits? Museum docents and informal educators are uniquely situated within the community. They are transmitters and translators of science information to broad audiences. Through interaction with the public, docents are well positioned to be informants of the knowledge beliefs, and feelings of science center visitors. They themselves are life-long learners, both constantly learning from the museum content around them and sharing this content with visitors. They are also members of a community where they live. In-depth interviews with museum informal educators and docents were conducted at a science center in coastal Pacific Northwest. This region has a potential to be struck by a great 9+ Mw earthquake and subsequent tsunami. During the interviews, docents described how they applied learning from natural hazard exhibits at a science visitor center to their daily lives. During the individual interviews, the museum docents described their awareness (knowledge, attitudes, and behaviors) of natural hazards where they live and work, the feelings evoked as they learned about their hazard vulnerability, the extent to which they applied this learning and awareness to their lives, such as creating an evacuation plan, whether

    Zoos serve as centers for both research and education. The challenge is to convey messages about their conservation projects while meeting visitor expectations, which often include recreation and entertainment. One way this can be achieved is through the design of immersive exhibits that draw visitors in and engage them with interactive educational elements. Regenstein African Journey (RAJ) opened at Lincoln Park Zoo in 2003 and was designed to take visitors on a simulated safari through Africa. Because visitor experience was a major design goal, we conducted a timing and tracking study to evaluate use of the building and educational components. For a 9-week period in 2003, we tracked 338 visitors to RAJ and recorded continuous data as they moved through the building. Data were collected on handheld computers that provided precise timing data. The median visit was 11.08 min, 41% of which was spent looking at animals and 9% of which was spent engaged with interpretive elements. We found significant differences in the way visitors used signage: those in groups without children spent more of their visit engaged with signage than those with children and visitors who spent more of their visit interacting socially spent less time engaged with signage. By understanding how visitors use the educational opportunities presented to them, we can better meet their expectations and more effectively achieve the goal of conservation education.

    2015-01-01

    To extend density limits in magnetic recording industry, two separate strategies were developed to build the storage bit in last decade, introduction of perpendicular magnetic anisotropy (PMA) and adoption of ferrimagnetism/antiferromagnetism. Meanwhile, these properties significantly improve device performance, such as reducing spin-transfer torque energy consumption and decreasing signal-amplitude-loss. However, materials combining PMA and antiferromagnetism rather than transition-metal/rare-earth system were rarely developed. Here, we develop a new type of ferrimagnetic superlattice exhibiting PMA based on abundant Heusler alloy families. The superlattice is formed by [MnGa/Co2FeAl] unit with their magnetizations antiparallel aligned. The effective anisotropy (Kueff) over 6 Merg/cm3 is obtained, and the SL can be easily built on various substrates with flexible lattice constants. The coercive force, saturation magnetization and Kueff of SLs are highly controllable by varying the thickness of MnGa and Co2FeAl layers. The SLs will supply a new choice for magnetic recording and spintronics memory application such as magnetic random access memory.

    We describe the amperometric detection of glucose using oriented nanowires with magnetic switching of the bioelectrochemical process. The fabrication process of the nanowires was prepared through controlled nucleation and growth during a stepwise electrochemical deposition, and it was characterized using scanning electron microscopy. Cyclic voltammetry and amperometry were used to study the magnetoswitchable property; this control was accomplished by changing the surface orientation of nanowires. Under the optimal condition, the amperometric response was also linear up to a glucose concentration of 0.1-16.0 mmol L(-1) with a sensitivity of 81 μA mM(-1). The detection limit was estimated for 4.8×10(-8) mol L(-1), defined from a signal/noise ratio of 3. It also exhibits good reproducibility and high selectivity with insignificant interference from ascorbic acid, acetoaminophen, and uric acid. The resulting biosensor was applied to detect the blood sugar in human serum samples without any pretreatment, and the results were comparatively in agreement with the clinical assay. PMID:25127595

    Cytoskeletal changes in transformed cells (LM-51) eshibiting obviously metastatic capabilities were investigated by utilization of double-fluorescent labelling through combinations of:(1) tubulin indirect immunofluorescence plus Rhodamine-phalloidin staining of F-actins;(2) indirect immunofluorescent staining with α-actinin polyclonal-and vinculin monoclonal antibodies.The LM-51 cells which showed metastatic index of >50% were derived from lung metastasis in nude mice after subcutaneous inoculation of human highly metastatic tumor DNA transfected NIH3T3 cell transformants.The parent NIH3T3 cells exhibited well-organized microtubules,prominent stress fibers and adhesion plaques while their transformants showed remarkable cytoskeletal alterations:(1)reduced microtubules but increased MTOC fluorescence;(2)disrupted stress fibers and fewer adhesion plaques with their protein components redistributed in the cytoplasm;(3)Factin-and α-actinin/vinculin aggregates appeared in the cytoplasm.These aggregates were dot-like,varied in size(0.1-0.4μm) and number,located near the ventral surface of the cells.TPA-induced actin/vinculin bodies were studied too.Indications that actin and α-actinin/vinculin redistribution might be important alterations involved in the expression of metastatic capabilities of LM-51 transformed cells were discussed.

  2. Surface dielectric barrier discharges exhibiting field emission at high pressures

    International Nuclear Information System (INIS)

    Surface dielectric barrier discharges (DBDs) are investigated experimentally in CO2 from atmospheric pressure up to supercritical conditions. Two discharge regimes are generated using 10 kHz ac excitation. The ‘standard’ regime is similar to previously studied surface DBDs in terms of onset voltage as a function of pressure, as well as electrical and optical emission characteristics. However, a ‘field-emitting’ regime emerges starting from 0.7 MPa that exhibits constant onset voltage up to 7.9 MPa, purely continuum emission spectra in the visible/near-infrared range and current waveforms similar to an atmospheric-pressure Townsend discharge with ionization instabilities. The maximum amount of negative charge deposited as a function of the applied voltage amplitude is consistent with the Fowler–Nordheim equation, which demonstrates the presence of field emission. Furthermore, this behavior cannot be attributed to the Townsend or streamer ionization mechanisms, secondary electron emission or non-discharge processes. No field-emitting structures are specially added to the electrodes. The onset voltage of the field-emitting regime does not follow the modified Paschen's law for field emission-assisted breakdown.

    Full Text Available Abstract Background To expand on the range of products which can be obtained from lignocellulosic biomass, the lignin component should be utilized as feedstock for value-added chemicals such as substituted aromatics, instead of being incinerated for heat and energy. Enzymes could provide an effective means for lignin depolymerization into products of interest. In this study, soil bacteria were isolated by enrichment on Kraft lignin and evaluated for their ligninolytic potential as a source of novel enzymes for waste lignin valorization. Results Based on 16S rRNA gene sequencing and phenotypic characterization, the organisms were identified as Pandoraea norimbergensis LD001, Pseudomonas sp LD002 and Bacillus sp LD003. The ligninolytic capability of each of these isolates was assessed by growth on high-molecular weight and low-molecular weight lignin fractions, utilization of lignin-associated aromatic monomers and degradation of ligninolytic indicator dyes. Pandoraea norimbergensis LD001 and Pseudomonas sp. LD002 exhibited best growth on lignin fractions, but limited dye-decolourizing capacity. Bacillus sp. LD003, however, showed least efficient growth on lignin fractions but extensive dye-decolourizing capacity, with a particular preference for the recalcitrant phenothiazine dye class (Azure B, Methylene Blue and Toluidene Blue O. Conclusions Bacillus sp. LD003 was selected as a promising source of novel types of ligninolytic enzymes. Our observations suggested that lignin mineralization and depolymerization are separate events which place additional challenges on the screening of ligninolytic microorganisms for specific ligninolytic enzymes.

    2011-07-01

    All cells derive nutrition by absorbing some chemical and energy resources from the environment; these resources are used by the cells to reproduce the chemicals within them, which in turn leads to an increase in their volume. In this study we introduce a protocell model exhibiting catalytic reaction dynamics, energy metabolism, and cell growth. Results of extensive simulations of this model show the existence of four phases with regard to the rates of both the influx of resources and cell growth. These phases include an active phase with high influx and high growth rates, an inefficient phase with high influx but low growth rates, a quasistatic phase with low influx and low growth rates, and a death phase with negative growth rate. A mean field model well explains the transition among these phases as bifurcations. The statistical distribution of the active phase is characterized by a power law, and that of the inefficient phase is characterized by a nearly equilibrium distribution. We also discuss the relevance of the results of this study to distinct states in the existing cells.

    Poor corneal penetration and short residence time on the ocular surface are two major bottlenecks for conventional ophthalmic formulations. To overcome the foregoing dilemmas, we prepared two novel formulations of pimecrolimus nanomicelles (PNM) with particle size of 37.85 ± 1.21 nm and thermosensitive hydrogel (PTH) for treating Keratoconjunctivitis Sicca (KCS). PNM were investigated by transmission electron microscopy (TEM), Malvern laser particle size analyzer, X-ray diffraction (XRD) system, and the content of drug in PNM was measured by high-performance liquid chromatography (HPLC). The drug loading and encapsulation efficiency reached to 7.57% ± 0.10% and 97.9% ± 1.26%, respectively. PTH displayed special gel-sol transition behavior with temperature increasing from 4 °C to 37 °C. The in vitro release profile demonstrated that PNM and PTH exhibited sustained-release behavior compared with free pimecrolimus oil-based eye drop (FPO). In addition, we established a mouse model of KCS induced by benzalkonium chloride to evaluate the therapeutic outcome of different pimecrolimus formulations. The production of tear, fluorescein staining scores and histopathologic examinations of the cornea were assessed in detail. The results confirmed that PNM had the best therapeutic effect among all formulations based on its higher drug encapsulation capability, favourable permeability and sustained release. All these indicated that PNM could serve as a potent ophthalmologic agent for KCS. PMID:26731192

  6. Semiparametric energy-based models of systems exhibiting criticality

    Science.gov (United States)

    Humplik, Jan; Tkacik, Gasper

    Over the last decade, several empirical studies have found evidence that many biological and natural systems exhibit critical fluctuations analogous to those observed during second-order phase transitions in equilibrium systems. In many cases, these fluctuations were shown to be equivalent to a thermodynamic version of Zipf's law-if the system is sufficiently large, then a log-log plot of the probability of a state vs. its rank yields a straight line with slope - 1 . Because the origin of critical fluctuations cannot be traced to a unique mechanism, it is important that data-driven phenomenological models of natural systems are flexible enough so as to easily capture any kind of criticality. Here we study a class of models with exactly this property. This class consists of energy-based models in which the exponential Boltzmann factor is replaced by an arbitrary nonlinear function. We demonstrate the usefulness of our method by modeling the spiking activity of a population of retinal neurons, and the distribution of light intensities in small patches of natural images. In light of recent work on models with hidden variables, the proposed method can separate interactions induced by an unknown fluctuating environment from interactions intrinsic to the system.

  7. A new theory of doped manganites exhibiting colossal magnetoresistance

    2005-06-01

    Rare earth manganites doped with alkaline earths, namely Re1-AMnO3, exhibit colossal magnetoresistance, metal insulator transitions, competing magnetic, orbital and charge ordering, and many other interesting but poorly understood phenomena. In this article I outline our recent theory based on the idea that in the presence of strong Jahn–Teller, Coulomb and Hund’s couplings present in these materials, the low-energy electronic states dynamically reorganize themselves into two sets: one set (ℓ) which are polaronic, i.e., localized and accompanied by large local lattice distortion, and another (b) which are non-polaronic and band-like. The coexistence of the radically different ℓ and states, and the sensitive dependence of their relative energies and occupation upon doping , temperature , magnetic field , etc., underlies the unique effects seen in manganites. I present results from strong correlation calculations using dynamical mean-field theory and simulations on a new 2-fluid model which accord with a variety of observations.

    In this work we focus on surfaces, which exhibit controlled, switchable wettability in response to one or more external stimuli as well as photocatalytic activity. For this we are inspired from nature to produce surfaces with a dual-scale hierarchical roughness and combine them with the appropriate inorganic and/or polymer coating. The combination of the hierarchical surface with a ZnO coating and a pH- or temperature-responsive polymer results in efficient photo-active properties as well as reversible superhydrophobic / superhydrophilic surfaces. Furthermore, we fabricate surfaces with unidirectional wettability variation. Overall, such complex surfaces require advanced design, combining hierarchically structured surfaces with suitable polymeric materials.

    Full Text Available PMD (Pelizaeus–Merzbacher disease, a CNS (central nervous system disease characterized by shortened lifespan and severe neural dysfunction, is caused by mutations of the PLP1 (X-linked myelin proteolipid protein gene. The majority of human PLP1 mutations are caused by duplications; almost all others are caused by missense mutations. The cellular events leading to the phenotype are unknown. The same mutations in non-humans make them ideal models to study the mechanisms that cause neurological sequelae. In the present study we show that mice with Plp1 duplications (Plp1tg have major mitochondrial deficits with a 50% reduction in ATP, a drastically reduced mitochondrial membrane potential and increased numbers of mitochondria. In contrast, the jp (jimpy mouse with a Plp1 missense mutation exhibits normal mitochondrial function. We show that PLP in the Plp1tg mice and in Plp1-transfected cells is targeted to mitochondria. PLP has motifs permissive for insertion into mitochondria and deletions near its N-terminus prevent its co-localization to mitochondria. These novel data show that Plp1 missense mutations and duplications of the native Plp1 gene initiate uniquely different cellular responses.

    Full Text Available The New South Wales Migration Heritage Centre was established in 1998. Since 2003 its physical presence has been located within Sydney’s Powerhouse Museum and it has had the strategic brief to record the memories of ageing migrants before their stories are lost. The Centre is, however, a museum without a collection; a heritage authority without heritage sites; a cultural institution whose main presence is in cyberspace. Among its high profile projects is one entitled Objects through time and another Belongings. Both focus on the ways in which objects can convey aspects of the migration experience. Belongings, the focus of this article, presents the remembered experiences of people who migrated to Australia after World War II, and seeks to highlight significant features of their experiences through asking them to share their memories and to nominate and talk about significant objects. As a project it grew out of movable heritage policy work within state government agencies, and its initiators – John Petersen, Kylie Winkworth and Meredith Walker – were central players in this development. It was also inspired by the National Quilt Register of the Pioneer Women’s Hut at Tumbarumba. With its object-centred approach and accompanying edited interview transcripts, Belongings provides a focus for exploring the messages and emphases that emerge when oral history interviews concerned with migration have the specific brief to ask about material culture and its significance. Belongings also enables an exploration of the layering of those messages that emerges when object captions are located back in the context of the oral history interviews from which they were extracted. As a virtual exhibition, Belongings also provides the opportunity to consider the challenges for museums (virtual and real when they need to condense the richness of migrant oral histories and life stories to captioned objects that can be put on display.

  12. Exhibiting evolution an essay upon the museum’s subjectivity

    Directory of Open Access Journals (Sweden)

    Pinna, Giovanni

    2009-12-01

    Full Text Available A museum is not only a physical place, a mere container of fragments of the cultural heritage. It is above all a unity of knowledge whose task of scientific research and analysis of the collections leads to an original interpretation of the world, to a specific culture, typical of each museum. Through its permanent exhibitions or any other means at its disposal, each museum conveys its cultural specificity to the visitor, a specificity which is different to that of other museums and does not intend to be objective. This paper aims to prove all the above by showing how, in different times and places, three important museums displayed three examples of evolution obtained form paleontology developing a totally subjective interpretation of the evolutionary process.

    El museo no es sólo un lugar físico, un simple contenedor de fragmentos del patrimonio cultural, es, sobretodo, una unidad de conocimiento cuya labor de investigación científica y análisis de las colecciones conduce a una interpretación del mundo totalmente original, a una cultura propia de cada museo. Utilizando las exposiciones permanentes, o cualquier otro medio a su disposición, cada museo comunica al público su especifidad cultural, que es diversa de la de otros museos y no quiere ser objetiva. Esto es cuanto el artículo pretende demostrar ilustrando cómo, en tiempos y lugares diferentes, tres grandes instituciones museísticas mostraron al público tres ejemplos de evolución obtenida de la paleontología desarrollando una interpretación totalmente subjetiva del proceso evolutivo.

    guests in different binding sites located within the same cavity. ExBox2(4+) forms complexes with C60 in which discrete arrays of aligned fullerenes result in single cocrystals, leading to improved material conductivities. When the substitution pattern of the Ex(n)Box(4+) series is changed to 1,3,5-trisubstituted benzenoid cores, the hexacationic cagelike compound, termed ExCage(6+), exhibits different kinetics of complexation with guests of varying sizes-a veritable playground for physical organic chemists. The organization of functionality with respect to structure becomes valuable as the number of analogues continues to grow. With each of these minor structural modifications, a wealth of properties emerge, begging the question as to what discoveries await and what properties will be realized with the continued exploration of this area of supramolecular chemistry based on a unique class of receptor molecules.

  5. Development of Nutrient Management Strategies for ASAL using Participatory Learning and Action Research (PLAR) Approach

    International Nuclear Information System (INIS)

    Participatory diagnosis of soil fertility problems and subsequent experimentation was carried out at Kibwezi Division, Makweni district, using Participatory learning and Action Research (PLAR) methodologies. results of the soil analysis showed that nitrogen (N), phosphorus (P) and carbon (C) were the most limiting nutrients to the crop production. Farmers were excited to learn how to identify deficiency symptoms of N and P by looking at plant leaves. Farmers also identified and implemented practical options under rain-fed and irrigated conditions for solving the soil fertility problems such as use of manure, fertilisers or a combination of both. Fertiliser application at the rate of 40N + 40P2O5 ha-1 and 60N + 60P2O5 ha-1 produced significantly yield responses under rain-fed conditions. However, application of 20 t ha-1 and 40 t ha-1 of farm yard manure had no effect on grain yield of maize. Maize gross margins were positive with increasing fertilizer application. Similarly, fresh yields of Chili showed marked yield increasing with increasing fertility conditions. In contrast, onions and tomatoes showed a corresponding smaller yield increase with fertility improvement. Chili, onions and tomatoes had positive gross margins as nutrient application was increased indicating that benefit was higher with increasing fertiliser inputs. The PLAR methodology provided farmers with knowledge and skills that helped them to change their attitude towards soil fertility improvement interventions

The major coat protein of viral particle (L1 plays a key role in the infection process. Our study aimed to isolate the HPV-16 L1 gene and analyze its sequence. Samples used were samples collected from the Department of Obstetrics and Gynaecology, Dr. Hasan Sadikin General Hospital, Bandung during the period of June to October 2010. In this study, the HPV-16 L1 sequence was analyzed from the viral deoxyribonucleic acid (DNA extracted from biopsy sample of cervical cancer patient biopsy samples.The HPV-16 L1 amplification was performed using the polymerase chain reaction with specific primer. The HPV infection in the cervical tissue was confirmed by commercial HPV genotyping test. The L1 fragment was cloned into plasmid and the insert of the recombinant clone pJET1.2/L1-16 was digested using BamHI and BgIII. The amplicon result showed HPV-16 L1 gene with a length of 1.595 base pairs. The sequence analysis of two samples using software BIOEDIT dan Basic Local Alignment Search Tool revealed a high level of sequence similarity to L1 HPV-16 from Thailand (99% and 97% as registered in GenBank. In conclusion, the L1 HPV-16 gene from Bandung isolates revealed variations from published sequence. Knowledge on L1 gene sequence may give additional information to the development of vaccine. Further study on vaccine development is currently ongoing using this HPV-16 clone that may be specific to Indonesian population.

Bioteknologi 13: 9-17. Anguilla bicolor bicolor, an eel species found in the waters of Indonesia, is become a potential export commodity for the country. Currently this species began to be cultured, by taking the larvas from the wild and reared in ponds. In aquaculture, the disease caused by bacteria are the main problems that limit production in the culture of eel. Restrictions on the use of anti-microbial substances causing a more environmentally friendly approach is needed to reduce disease outbreak in aquaculture. It is known that bacterial communities associated with animals have an important role for the survival of its modulation of host’s microbiota through feed supplements such as probiotics and prebiotics can increase the growth and survival of fish. This research aimed to determine the type of bacteria that can be isolated and characterized from the gastrointestinal tract of A. bicolor bicolor and their potential as a probiotic candidates. Bacteria from the gastrointestinal tract of the fish were isolated and characterized. Observations made include the amount of bacteria in the gastrointestinal tract, the morphological characters of each isolate, and the identification of each isolate. The ability of hydrolysis (hemolytic and proteolytic activity and antagonistic against pathogens in fish (Aeromonas hydrophila were also measured. From the gastrointestinal tract of A. bicolor bicolor, 11 isolates were obtained, which were fell into 9 species according to their characters. Two candidates of bacteria which were expected to be used as probiotics for eel were Citrobacter freundii and Bacillus subtilis.

    Full Text Available Red tilapia is a good commodity to be developed because it has a high nutritional value composition, with a protein content 17.8%, fat 2.8%, and others composition. The fillet of red tilapia fish is easy to spoil, because of S. aureus, Salmonella sp., and other microbes. Many methods are used to save and preserve the quality of fillet, such fillet preparation through good sanitation practices, cooling process, but the effort were not optimal. The objectives of this study were to 1 evaluate the potency of antibacterial produced by Lactobacillus acidophilus and Bifidobacteria biffidum to inhibit the growth of spoilage bacteria that contaminated the red tilapia fillet; 2 evaluate the effect of antibacterial compounds produced by Lactobacillus acidophilus and Bifidobacteria biffidum of inhibiting the setback fillet quality, 3 determine the shelf life of red tilapia fillet at room temperature. Antibacterial activity test is done by using the well diffusion method; the rate of deterioration of quality of fish tests done by observing the organoleptic parameters, pH measurement test, total volatile base method. Total number of bacteria were performed by Standard Plate Count (SPC test. The LABs are able to inhibit the growth of spoilage bacteria Pseudomonas aeruginosa about 8.67-9.00 mm and Listeria monocytogenes about 8.33-9.00 mm through the well diffusion method. pH values about 5.71-5.74, TVB values about 1,26-21.43 with SPC test about 1.39-4.83 CFU/mL. The antibacterial compounds could inhibit the rate of deterioration of quality red tilapia fillets until 14 hours.

    Full Text Available The bat is very important for human life, because of their  role as pollinator of plants, as a producer oforganic fertilizer,  and as food.  In Northern Celebes fruit eating bats serve as exotic food, so the presenceof bats were threatened to be extinct due to uncontrolled hunting.  The changes of the forest for plantationlands, damage the habitats and the bats were forced to migrate out.   The aim of the study was to identifythe fruit eating bats of Celebes.  Morphometry of body size, skull,  and physical characteristics were usedin determining the types and distribution  of fruit eating bats in Celebes. The field survey was carried outat the hunting area, bat dealers, and bat sellers. The collected data were analyzed by using descriptivemethod and interpreted by narrating to describe the entire study. The result show that  there were fivetypes of fruit eating bats : i.e.  kalong sulawesi (Acerodon celebensis,  paniki pallas (Nyctimene cephalotes,codot wallet (Thoopterus nigrescens, nyap biasa (Rousettus amplexicaudatus, and  kalong hitam  (Pteropusalecto.

    2011-01-01

    A functional analysis identified the reinforcer maintaining feces throwing and spitting exhibited by a captive adult chimpanzee (Pan troglodytes). The implementation of a function-based treatment combining extinction with differential reinforcement of an alternate behavior decreased levels of inappropriate behavior. These findings further demonstrate the utility of function-based approaches to assess and treat behavior problems exhibited by captive animals.

  8. Ape Behavior in Two Alternating Environments: Comparing Exhibit and Short-Term Holding Areas

    DEFF Research Database (Denmark)

    Ross, Stephen R.; Wagner, Katherine E.; Schapiro, Steven J.;

    2010-01-01

    In many facilities, primates are voluntarily transferred between different enclosures on a daily basis to facilitate animal husbandry and exhibit maintenance. This procedure is particularly relevant in the management of great apes living in zoos, where the requirements of functional management must...... be balanced with the desire to maintain enriching and naturalistic exhibit enclosures that benefit ape residents and attract the visiting public. In these settings, examinations of ape behavior and welfare typically focus exclusively on activity in the primary exhibit area. However, physical, social...... and sensory experiences unique to each area may shape different patterns of behavior. In the current study, zoo-living chimpanzees and gorillas were moved each day from exhibit areas to off-exhibit holding areas for a short duration as a part of regular management procedures. Behavioral data indicated species...

  9. Using Keyword-Based Approaches to Adaptively Predict Interest in Museum Exhibits

    Science.gov (United States)

    Bohnert, Fabian; Zukerman, Ingrid

    Advances in mobile computing and user modelling have enabled technologies that help museum visitors select personally interesting exhibits to view. This is done by generating personalised exhibit recommendations on the basis of non-intrusive observations of visitors' behaviour in the physical museum space. We describe a simple methodology for manually annotating museum exhibits with bags of keywords (viewed as item features), and present two personalised keyword-based models for predicting a visitor's viewing times of unseen exhibits from his/her viewing times at visited exhibits (viewing time is indicative of interest). Our models were evaluated with a real-world dataset of visitor pathways collected by tracking visitors in a museum. Both models achieve a higher predictive accuracy than a non-personalised baseline, and perform at least as well as a nearest-neighbour collaborative filter.

  10. Musealization without museology: national museums and fashion exhibitions between history, theory and practice

    Directory of Open Access Journals (Sweden)

    Stefan Žarić

    2016-03-01

    Full Text Available Studies of the theory and history of fashion, which were up until recently grouped with culture studies, gender studies, communicology, art history and anthropology are, on the academic map of the 21st century being established as separate disciplines. Consolidating these contexts, the affirmation of fashion studies has been most prevalent within the museology of fashion, as it - or rather – fashion museology is becoming one of the leading tendencies within contemporary museum practices. This paper views fashion as a specific kind of system, coded through sociocultural codes, and finds the reason for the ever-increasing number of exhibitions of fashion on the international as well as the national museum scene in the codes of fashion which oscillate between the aesthetic and the commercial. By affirming fashion as an art form on the one hand and increasing the profitability of the institution on the other, fashion exhibitions enable museums to become „fashionable“ – to keep up with contemporary, more liberal exhibition concepts. Despite the fact that in this year there have been a large number of fashion exhibitions in national museums, fashion is still without its own museology, a scientific theory which would explain it as a museum phenomenon. The exhibits are interpreted historically, while explaining their utilitarian and aesthetic value, while the question of why fashion is exhibited as an art form or a kind of cultural production to the consumer of the exhibition - the visitor – remains unanswered. By analyzing historical events which conditioned the museum exhibiting of fashion as well as the different conceptions of its exhibition, the author strives to – through the juxtaposition of international and national exhibitions catch sight of the causes of the lack of a museology of fashion, and open up the issue of its affirmation within the professional academic and museum community of Serbia.

    Full Text Available The aim of the article. The article presents comparative analysis of exhibition and fair activities, reviews essence of such definitions as «exhibition» and «fair», generalizes and systematizes classification of different kinds of exhibitions, grounds expediency of application of this marketing communication tool when outputting industrial products into new sales markets. The results of the analysis. The article analyzes the exhibition activities as one of the current and future marketing communication tools of domestic enterprises. Examples of the largest exhibition centers in Ukraine in general, and in the Sumy region in particular are shown. The essence of the concept of «exhibition» and definition of «fair» are analysed. It is noted that the main difference between these measures is in their form (product demonstration, explanation of the features and operation of its production or sale of goods. It is indicated the appearance synthesized measures («sales exhibitions», «fairs» that share features of both types of events. An exhibition benefits for businesses as measures that outline the prospects of certain activities and is a kind of «window into the future». It is indicated that costs about a third of the budget for the communication exhibitions is economically feasible and effective. It is considered mission, goals and objectives of exhibitions. The comparative analysis of exhibition and fair activities, which have different and common features associated with unique capabilities informing different target audiences about competitive advantagesof certain producers, which allowed the application of the noted features exhibitions to domestic producers. It is proved that the task of removing domestic products to new markets (especially international, weak enterprises survive the economic crisis, a successful competition in the various markets, the increase in sales is impossible to realize without this tool of marketing

  12. The expositive discourse as pedagogical discourse: studying recontextualization in the production of a science museum exhibition

    2016-06-01

    In this paper I report on the sociological and educational particulars of The Biodiscovery Space exhibition of the Life Museum of the Oswaldo Cruz Foundation in Rio de Janeiro, Brazil, using Basil Bernstein's framework of pedagogic discourse and recontextualization. Data for analysis was obtained from interviews with the exhibition developers, field observations of museum visitors and analysis of exhibition documents. Using the ideas of power, classification and framework, among others, I analyzed the recontextualization process of the production of expositive discourse. Thus, working with Bernstein's idea of classification, I explain the relationship between the discourses of the science of biology, history of science, museology, education, and communication in order to produce an expositive discourse. I also make explicit how agents of the Official Recontextualization Field of the Museum and the Pedagogic Recontextualization Field "....of the Museum determine partly the final expositive discourse of an exhibition". Using the idea of a pedagogic discourse framework, I discuss how the constraints imposed by objects and texts in exhibitions help to create a specific manner of visitor interaction with these elements, "even if they have some autonomy". Considerations about the audience and the intended process of acquisition are presented, when I discuss the control strategies of the exhibition. I propose that the Biodiscovery Space exhibit has a visible pedagogy. Finally, using the collected data I discuss the power tensions created in the production of expositive discourse showing how distributive, recontextualization and evaluation rules work in the context of exhibitions. The study of the dynamics in forming the expositive discourse using Bernstein's framework reveals the individuals and institutions, the selection criteria, the negotiations and the power relations involved. It has the potential to assist both educators and researchers in the museum education

    Directory of Open Access Journals (Sweden)

    Katia Mazzucco

    2011-12-01

    Full Text Available Between 1939 and 1948 the Warburg Institute organized a series of photographic exhibitions. The most important of these, held in 1941, was entitled English Art and the Mediterranean. The various exhibitions all presented distinct research themes according to indications by the Warburg Library. They were also aligned technically as well as in their methodological perspective: the exhibition had no original works, only displaying photographic reproductions, and the exhibitions’ major themes were intended to provide a comparative and multidisciplinary overview of issues that had already been discussed in the area of art history. These events represented a significant encounter between the late nineteenth-century German school of aesthetics and art history and the British cultural and academic contexts. The exhibitions also presented new approaches to British art, through their original conception, as well as a demonstration of a particular sensitivity to visual culture, in terms of a broader understanding of images.

    Puerto Rico was selected as one of the venues for the exhibit “From Earth to the Solar System” (FETTSS) during the month of October 2011. A set of outreach activities were organized to take place during the month of October aligned with the FETTSS themes. These activities included the following: 1) Main Exhibit, 2) Guided tours for school groups, 3) Planet Festival, 4) Film Festival and 5) Astronomy Conferences. We describe this experience and in particular the work with a group of undergraduate students from the University of Puerto Rico (UPR) that assisted in the outreach events. Among this group were three blind students. The FETTSS exhibit included a set of tactile and Braille images for the blind and visually impaired. A special exhibit was prepared with additional adapted materials for the visually impaired. This allowed blind visitors to participate and the general public to become more aware of the needs of this population.

  9. Survey of absence. The use of photographic data for the survey of temporary art exhibitions.

    Full Text Available Modern Art Exhibitions succeeded in conveying long-lasting ideas and meanings despite their ephemeral nature. Art history and Museum studies recently started to focus on the Exhibition as a medium, requiring precise graphic reconstructions of exhibit designs for critical and theoretical purposes. Exhibitions were rarely designed through graphic devices such as the project; they were usually a result of improvisation processes. In this sense, photographs are the only documents for graphic reconstructions of temporary art spaces. Nevertheless, the photographic datum has been over-edited in its span of life for more than one reason: it requires a critical approach to be used as a source. The use of digital tools for photography can lead to satisfactory results when applied to humanities.
