    Full Text Available The vocal repertoire of the Azure Jay Cyanocorax caeruleus (Vieillot, 1818 is approached from a quali-quantitative point of view. The qualitative analysis was carried out both in the field and in captivity: the quantitative analysis was made only in captivity. Social acoustic communication in the Azure Jay is achieved through the use of two types of call: basic and intermediate calls. Fourteen basic calls are identified and presented through sonograms: the sotto voce song (courtship call is related only to courtship and the social call is interpreted as the song in the Azure Jay. The intermediate calls are recombinations of the basic calls uttered during an alteration in motivation level. Examples of them are presented through sonograms of vocalizations recorded during mobbing predators and intraspecific agonistic contexts. The social, social-alarm, contact, flight, proximity, threat and social identity calls were those most frequently uttered by daylight: the other calls represented around 15% of the total number of utterances. The hypothesis of the evolution in American Jays, which tends to simplification of vocal repertoire (HARDY, 1961; 1969, is analysed; C. caeruleus seems to have a small actively-used repertoire.

    The cognition of green jays (Cyanocorax yncas), a non Corvus corvid species, was investigated by using the string-pulling paradigm. Five adult green jays performed a vertical string-pulling task in which they had to retrieve a worm attached to the end of a vertical hanging string while sitting on their perch. In the first experiment, three of the subjects managed to retrieve the worm by pulling on the string with their beaks and stepping on the resulting loop, and thereafter repeating this sequence until the worm was accessible. When subjects were given a choice between two strings in subsequent experiments 2-4, they chose at random between the string connected to the worm and the one connected to a slice of a wooden dowel. In experiment 5, subjects that had failed the previous discrimination series were able, nevertheless, to solve a more stringent vertical string array in which they had to pull up the whole length of the string without any visual access to the worm at the end. We discuss green jays' performance in comparison with other corvid species in which cognition has been more extensively investigated. Copyright © 2017 Elsevier B.V. All rights reserved.

  5. Diet and feeding behavior of the White-naped Jay, Cyanocorax cyanopogon (Wied, 1821 (Aves, Passeriformes, Corvidae in a disturbed environment in central Brazil

    Directory of Open Access Journals (Sweden)

    RAM Barros

    Full Text Available The White-naped Jay Cyanocorax cyanopogon (Wied, 1821 is an omnivorous and opportunistic species, with a multifarious diet. In view of the scarcity of available data in the literature, the aim was to investigate and describe the bird's diet, location of food items, foraging tactics, actual feeding behavior and intraspecific interactions, as a means of defining the items consumed. The study was carried out in a Cerrado area in the Araguaia Campus of the Federal University of Mato Grosso – UFMT, in Pontal do Araguaia, Mato Grosso State, Brazil, from August to December, 2006, and from April to October, 2010. All the feeding events were recorded through 136 hours of animal focal sampling, whereby it was shown that these birds predominantly consume animal nutrients, replenished by vegetable items and human food-waste. Arthropods were predominant in the diet, with ants as the most abundant and frequent item. The fruits, flowers and seeds of eleven plant species were also consumed. Food-waste, representing about 1/10 of the total, was constantly consumed even when other food sources were available. Although active among the various strata, foraging is mainly on the ground. In the event of food-scarcity, the strategy employed is the hierarchical deployment of the members of various-sized groups, with the avoidance of direct competition. This versatility during all seasons, confirms total adaptation to the anthropic environment surrounded by native habitats that characterized the study site.

  2. Thermodynamics of the DNA binding of phenothiazinium dyes toluidine blue O, azure A and azure B

    International Nuclear Information System (INIS)

    Paul, Puja; Suresh Kumar, Gopinatha

    2013-01-01

    Highlights: • DNA binding of toluidine blue O, azure A and azure B was driven by negative enthalpy and positive entropy changes. • The DNA binding affinity of the dyes varied as toluidine blue O > azure A > azure B. • The small heat capacity changes indicated hydrophobic contribution in the binding process. • The salt dependent study suggested involvement of weak electrostatic interactions. • DNA thermal stabilization varied as toluidine blue O > azure A > azure B. -- Abstract: The DNA binding of toluidine blue O (TBO), azure A and azure B was characterised by isothermal titration calorimetry, differential scanning calorimetry and thermal melting studies. The DNA binding affinity of TBO was the highest followed by azure A and azure B. The binding in each case was exothermic with a positive entropy change. The affinity of the binding decreased as the [Na + ] concentration increased. The non electrostatic contribution to the standard Gibbs energy remained the same over the range of (10 to 100) mM [Na + ]. The negative change in heat capacity of the binding revealed a substantial hydrophobic contribution in the DNA binding of these dyes. An enthalpy–entropy compensation was observed in each system. The binding of these dyes stabilised the DNA against thermal strand separation. The energetics of the DNA binding of these dyes correlate well with the structural data that suggest their utility as potential DNA targeting agents

    A comparison has been made between reticulocyte preparations stained with purified azure B and with several commerically available batches of brilliant cresyl blue and new methylene blue. Marked variations were observed in the composition and staining performances of the various batches of the two commerically available dyes. Although there were no significant differences in reticulocyte counts obtained with these two dyes, varying amounts of an extraneous, particulate dye deposit were present in these preparations, making accuracte counting both tedious and timeconsuming. Purified azure B, on the other hand, gave reproducibly stained, deposit-free preparations. Reticulocyte counts obtained from azure B preparations correlated almost exactly with those determined using new methylene blue. Purified azure B is therefore recommended as a convenient reticulocyte stain for routine use. Images PMID:64475

    Full Text Available We discuss the applicability of the Microsoft cloud computing platform, Azure, for bioinformatics. We focus on the usability of the resource rather than its performance. We provide an example of how R can be used on Azure to analyse a large amount of microarray expression data deposited at the public database ArrayExpress. We provide a walk through to demonstrate explicitly how Azure can be used to perform these analyses in Appendix S1 and we offer a comparison with a local computation. We note that the use of the Platform as a Service (PaaS offering of Azure can represent a steep learning curve for bioinformatics developers who will usually have a Linux and scripting language background. On the other hand, the presence of an additional set of libraries makes it easier to deploy software in a parallel (scalable fashion and explicitly manage such a production run with only a few hundred lines of code, most of which can be incorporated from a template. We propose that this environment is best suited for running stable bioinformatics software by users not involved with its development.

  9. Quantification of cellulase activity using cellulose-azure.

    Lai, Takwai E; Pullammanappallil, Pratap C; Clarke, William P

    2006-03-15

    Despite wide application of cellulose-azure as a substrate for measuring cellulase activity, there is no quantification of hydrolysis rate or enzymatic activities using this substrate. The aim of this study was to quantify the hydrolysis rate in terms of product formation and dye released using cellulose-azure. The amount of dye released was correlated with the production of glucose and the enzyme concentrations. It is shown that the lack of correlation can be due to (1) repression of the release of the azure-dye when azure-dye accumulates, (2) presence of degradable substrates in the cellulase powder which inflate the glucose measurements and (3) the degradation of cellulose which is not linked to the dye in the cellulose-azure. Based on the lack of correlation, it is recommended that cellulose-azure should only be applied in assays when the aim is to compare relative activities of different enzymatic systems.

  13. A thermodynamic investigation on the binding of phenothiazinium dyes azure A and azure B to double stranded RNA polynucleotides

    International Nuclear Information System (INIS)

    Khan, Asma Yasmeen; Suresh Kumar, Gopinatha

    2015-01-01

    Highlights: • The binding affinity of azure B was higher than azure A to the RNAs. • The binding of dyes stabilized the melting of poly(A).poly(U) and poly(I).poly(C). • Binding of azure A was enthalpy dominated but azure B binding was favoured by both enthalpy and entropy. • Nonpolyelectrolytic forces were found to play a crucial role in the binding process. • Enthalpy–entropy compensation phenomenon was seen in all the systems. - Abstract: The thermodynamics of the reactions of the two phenothiazinium dyes azure A and azure B with the three double stranded ribonucleic acids, poly(A).poly(U), poly(C).poly(G), poly(I).poly(C) were investigated using DSC and ITC. The bound dyes stabilized the RNAs against thermal strand separation. The binding of azure A to the RNAs was predominantly enthalpy dominated while the binding of azure B was favoured by both negative enthalpy and favourable entropy changes. Although electrostatic interaction had a significant role in the binding, non-polyelectrolytic forces dominated the binding process. The negative values of heat capacity changes for the binding suggested a substantial hydrophobic contribution to the binding process. The overall binding affinity of both the dyes to the RNAs varied in the order, poly(A).poly(U) > poly(C).poly(G) > poly(I).poly(C).

  14. Early Observations on the Performance of Windows Azure

    Directory of Open Access Journals (Sweden)

    Zach Hill

    2011-01-01

    Full Text Available A significant open issue in cloud computing is the real performance of the infrastructure. Few, if any, cloud providers or technologies offer quantitative performance guarantees. Regardless of the potential advantages of the cloud in comparison to enterprise-deployed applications, cloud infrastructures may ultimately fail if deployed applications cannot predictably meet behavioral requirements. In this paper, we present the results of comprehensive performance experiments we conducted on Windows Azure from October 2009 to February 2010. In general, we have observed good performance of the Windows Azure mechanisms, although the average 10 min VM startup time must be accounted for in application design. We also present performance and reliability observations and analysis from our deployment of a large-scale scientific application hosted on Azure, called ModisAzure, that show unusual and sporadic VM execution slowdown of over 4× in some cases and affected up to 16% of task executions at times. In addition to a detailed performance evaluation of Windows Azure, we provide recommendations for potential users of Windows Azure based on these early observations. Although the discussion and analysis is tailored to scientific applications, the results are broadly applicable to the range of existing and future applications running in Windows Azure.

    Scott, J A; Untereiner, W A

    2004-06-01

    Azure dye-impregnated sheep's wool keratin (keratin azure) was incorporated in a high pH medium and overlaid on a keratin-free basal medium. The release and diffusion of the azure dye into the lower layer indicated production of keratinase. Fifty-eight fungal taxa, including 49 members of the Arthrodermataceae, Gymnoascaceae and Onygenaceae (Order Onygenales), were assessed for keratin degradation using this method. The results were comparable to measures of keratin utilization reported in studies using tests based on the perforation or erosion of human hair in vitro.

  18. Spectroscopic studies on the binding interaction of phenothiazinium dyes toluidine blue O, azure A and azure B to DNA

    Science.gov (United States)

    Paul, Puja; Suresh Kumar, Gopinatha

    2013-04-01

    In this study a detailed characterization of the binding aspects of three phenothiazinium dyes, toluidine blue O (TBO), azure A and azure B with herring testes DNA is presented employing spectroscopic techniques. The absorbance and fluorescence properties of these dyes have been remarkably modified upon binding with DNA and the interaction is manifested through noncooperative binding as revealed form non-linear Scatchard plots with negative slopes at all binding ratios. The binding clearly revealed the high preference of TBO to DNA followed by the other two dyes azure A and azure B. The affinity of TBO was higher by about two times than that of the azures. From the series of studies using absorption, steady-state emission, the effect of ferrocyanide ion-induced steady-state fluorescence quenching, fluorescence polarization anisotropy, circular dichroism, the mode of binding of these dyes to the DNA double helix has been substantiated to be principally intercalative in nature. The stoichiometry of the association of these dyes to DNA was determined by the continuous variation analysis of Job from fluorescence data. The conformational aspects of the interaction was delineated from circular dichroism studies wherein higher perturbation was observed with TBO. Hydrodynamic study using viscosity measurements of linear rod like DNA confirmed that the binding was intercalative and strongest for TBO and weaker for azure A and azure B. The utility of the present work lies in exploring the potential binding applicability of these dyes to DNA for their development as effective therapeutic agents.

    This manuscript presents spectroscopic characterization of the interaction of two phenothiazinium dyes, azure A and azure B with double stranded (ds) ribonucleic acids, poly(A).poly(U), poly(C).poly(G) and poly(I).poly(C). Absorbance and fluorescence studies revealed that these dyes bind to the RNAs with binding affinities of the order 106 M-1 to poly(A).poly(U), and 105 M-1 to poly(C).poly(G) and poly(I).poly(C), respectively. Fluorescence quenching and viscosity data gave conclusive evidence for the intercalation of the dyes to these RNA duplexes. Circular dichroism results suggested that the conformation of the RNAs was perturbed on interaction and the dyes acquired strong induced optical activity on binding. Azure B bound to all the three RNAs stronger than azure A and the binding affinity varied as poly(A).poly(U) > poly(C).poly(G) > poly(I).poly(C) for both dyes.

    It has been suggested that achieving a chromogenic endpoint with an absorbance read at 600 nm or greater will reduce the degree of spectral interference in many colorimetric methods. We have examined a uricase/peroxidase-based system utilising a novel oxygen acceptor (azure-D2) as chromogen which produces a chromophor with an absorbance which can be measured at 600 nm (Synermed). Results (median, range, mumol/l) obtained on patient sera (n = 113) using the Synermed method (297; 38-847) were lower than those obtained using a 293 nm uricase method (Du Pont Ltd., 312; 62-874) (p 0.05) from the method group mean (Synermed = -29.315 + 1.0570 NEQAS). Bilirubin had a negative effect (p 0.05) but both ascorbic acid (100 mumol/l reducing uric acid by 68 mumol/l) and N-acetylcysteine (3 mmol/l reducing uric acid by 95 mumol/l) had significant negative effects (p 0.05) but serum storage for 72 hours at room temperature resulted in a significant (p < 0.0005) increase in measured uric acid. The Synermed method is a precise and accurate assay for serum uric acid. However, although generally showing low levels of spectral interference, chemical interferences in the assay from antioxidant components of serum may be problematic. This paper shows that the use of longer wavelengths of detection can reduce the significance of common spectral interferences.

    Many organizations have interest in using NASA property on KSC. The purpose of this document is to consolidate the goals of ecosystem management associated with Florida Scrub-Jays and compliance with the Endangered Species Act (ESA) in order to streamline and reduce the costs of facility planning, impact assessment, and impact minimization. This will simplify the process and reduce regulatory uncertainty.However, the resulting process must be consistent with the Merritt Island National Wildlife Refuge (MINWR) Comprehensive Conservation Plan (CCP). In addition, this document considers anticipated construction impacts on KSC during the next 10 years and summarizes priorities in a spatially explicit manner. The document describes anticipated compensation requirements to facilitate restoration of degraded habitat in areas most important to the KSC Scrub-Jay population through resources provided to MINWR. The plan assumes that all construction on KSC is compensated on KSC.

    The performances of two standardized Romanowsky stains (azure B/eosin and azure B/methylene blue/eosin) have been compared with each other and with a methylene blue/eosin stain. Visible-light absorbance spectra of various hematological substrates have been measured. These have been analyzed in terms of the quantities of bound azure B, methylene blue and eosin dimers and monomers, and in terms of the CIE color coordinates. It has been found that the addition of methylene blue to azure B/eosin produces little change in performance, at least using these two analytical methods. Methylene blue/eosin does not produce the purplish colorations typical of the Romanowsky effect. This is due not to differences between the spectra of methylene blue and azure B, but to the fact that methylene blue does not facilitate the binding of eosin to cellular substrates to the same extent as azure B.

    Methylene blue was synthesized in 1877 and soon found application in medicine, staining for microscopy and as an industrial dye and pigment. An enormous literature has accumulated since its introduction. Early on, it was known that methylene blue could be degraded easily by demethylation; consequently, the purity of commercial samples often was low. Therefore, demethylation products, such as azures and methylene violet, also are considered here. The names and identity of the components, their varying modes of manufacture, analytical methods and their contribution to biological staining are discussed.

    The Florida Scrub Jay is endemic to Florida. The John F. Kennedy Space Center (KSC) provides habitat for one of the three largest populations of the Florida Scrub Jay. This threatened bird occupies scrub, slash pine flatwoods, disturbed scrub, and coastal strand on KSC. Densities of Florida Scrub Jays were shown to vary with habitat characteristics but not necessarily with vegetation type. Relationships between Florida Scrub Jay densities and habitat characteristics were used to develop a habitat model to provide a tool to compare alternative sites for new facilities and to quantify environmental impacts. This model is being tested using long term demographic studies of colorbanded Florida Scrub Jays. Optimal habitat predicted by the model has greater than or equal to 50 percent of the shrub canopy comprised of scrub oaks, 20-50 percent open space or scrub oak vegetation within 100 m of a ruderal edge, less than or equal to 15 percent pine canopy cover, a shrub height of 120-170 cm, and is greater than or equal to 100 m from a forest. This document reviews life history, social behavior, food, foraging habitat, cover requirements, characteristics of habitat on KSC, and habitat preferences of the Florida Scrub Jay. Construction of the model and its limitations are discussed.

    Poly(A) has significant relevance to mRNA stability, protein synthesis and cancer biology. The ability of two phenothiazinium dyes azure A (AA) and azure B (AB) to bind single-stranded poly(A) was studied by spectroscopic and calorimetric techniques. Strong binding of the dyes and the higher affinity of AA over AB were ascertained from absorbance and fluorescence experiments. Significant perturbation of the circular dichroism spectrum of poly(A) in the presence of these molecules with formation of induced CD bands in the 300-700 nm region was observed. Strong emission polarization of the bound dyes and strong energy transfer from the adenine base pairs of poly(A) suggested intercalative binding to poly(A). Intercalative binding was confirmed from fluorescence quenching experiments and was predominantly entropy driven as evidenced from isothermal titration calorimetry data. The negative values of heat capacity indicated involvement of hydrophobic forces and enthalpy-entropy compensation suggested noncovalent interactions in the complexation for both the dyes. Poly(A) formed a self-assembled structure on the binding of both the dyes that was more favored under higher salt conditions. New insights in terms of spectroscopic and thermodynamic aspects into the self-structure formation of poly(A) by two new phenothiazinium dyes that may lead to structural and functional damage of mRNA are revealed from these studies.

    The spatial orientation interaction mechanism of chondroitin sulfate (CS) and azure A (AA) was studied by spectrometry. The maximum binding number (N = 151) and the binding equilibrium constant (K = 5. 24 x 10(4)) were obtained. The molecular binding model of the interaction between AA and CS was established. The influence of the molar ratio of AA/CS, ethanol, hydroxypropyl-beta-cyclodextrin, triton X-100 and NaCl on the spectra of AA-CS complex was investigated. We conclude that the color change of complex depends on not only the electrostatic interaction between AA and CS but also the density of AA binding on CS. And the formation of the absorption peak at 550 nm and the color change of complex result mainly from the hydrophobic interaction between AA and AA binding on CS.

    Methylene blue (MB) is reported to possess diverse pharmacological actions and is attracting increasing attention for the treatment of neurodegenerative disorders such as Alzheimer's disease. Among the pharmacological actions of MB, is the significant inhibition of acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE). These activities may, at least in part, underlie MB's beneficial effects in Alzheimer's disease. MB is metabolized to yield N-demethylated products of which azure B, the monodemethyl metabolite, is the predominant species. Azure B has been shown to be pharmacologically active and also possesses a variety of biological actions. Azure B therefore may contribute to the pharmacological profile of MB. Based on these considerations, the present study investigates the possibility that azure B may, similar to MB, act as an inhibitor of human AChE and BuChE. The results document that azure B inhibits AChE and BuChE with IC{sub 50} values of 0.486 μM and 1.99 μM, respectively. The results further show that azure B inhibits AChE and BuChE reversibly, and that the modes of inhibition are most likely competitive. Although the AChE and BuChE inhibitory activities of azure B are twofold and fivefold, respectively, less potent than those recorded for MB [IC{sub 50}(AChE) = 0.214 μM; IC{sub 50}(BuChE) = 0.389 μM] under identical conditions, azure B may be a contributor to MB's in vivo activation of the cholinergic system and beneficial effects in Alzheimer's disease. - Highlights: • Methylene blue (MB) is a known inhibitor of AChE and BuChE. • Azure B, the major metabolite of MB, also is an inhibitor of AChE and BuChE. • Azure B may be a contributor to MB's in vivo activation of the cholinergic system. • Azure B may contribute to MB's potential in Alzheimer's disease therapy.

    In this paper, the comparative binding behavior of antimalarial drug azure A, azure B and azure C with bovine serum albumin (BSA) has been studied. The interaction has been confirmed by multispectroscopic (UV, fluorescence, Fourier transform infrared (FT-IR), and circular dichroism) and molecular docking techniques. The experimental results show that azure B has the highest BSA binding affinity followed by azure A and azure C. The experimental evidence of binding showed a static quenching mechanism in the interaction azures with BSA. The isothermal titration calorimetry result reveals that the binding was exothermic with positive entropy contribution in each case. The thermodynamic parameters ΔH, ΔG, and ΔS at 25°C were calculated, which indicates that the weak van der Waals forces and hydrogen bonding rather than the hydrophobic effect played an important role in the interaction. According to the theory of Förster nonradiative energy transfer, the distance (r) between the donor (BSA) and acceptor azures found to be azures-BSA system. Overall, experimental studies characterize the interaction dynamics and energetics of the binding of three toxic analogs towards the physiologically relevant serum albumins. We hope, the outcome of this work will be most helpful for synthesizing a new type of phenothiazinium derivatives of the better therapeutic application. Copyright © 2017 John Wiley & Sons, Ltd.

  3. Azure C Targets and Modulates Toxic Tau Oligomers.

    2018-03-01

    Alzheimer's disease (AD) is the most common age-related neurodegenerative disorder affecting millions of people worldwide. Therefore, finding effective interventions and therapies is extremely important. AD is one of over 20 different disorders known as tauopathies, characterized by the pathological aggregation and accumulation of tau, a microtubule-associated protein. Tau aggregates are heterogeneous and can be divided into two major groups: large metastable fibrils, including neurofibrillary tangles, and oligomers. The smaller, soluble and dynamic tau oligomers have been shown to be more toxic with more proficient seeding properties for the propagation of tau pathology as compared to the fibrillar Paired Helical Filaments (PHFs). Therefore, developing small molecules that target and interact with toxic tau oligomers can be beneficial to modulate their aggregation pathways and toxicity, preventing progression of the pathology. In this study, we show that Azure C (AC) is capable of modulating tau oligomer aggregation pathways at micromolar concentrations and rescues tau oligomers-induced toxicity in cell culture. We used both biochemical and biophysical in vitro techniques to characterize preformed tau oligomers in the presence and absence of AC. Interestingly, AC prevents toxicity not by disassembling the oligomers but rather by converting them into clusters of aggregates with nontoxic conformation.

  4. The use of starch azure for measurement of alpha-amylase activity.

    2018-03-01

    Despite being widely used, there is no standard protocol for α-amylase activity measurement with starch azure substrate. Boiling pre-treatment of starch azure suspension increased the reaction rate of hydrolysis catalysed by human salivary α-amylase (HSA) or porcine pancreatic α-amylase (PPA) and the sensitivity of spectrophotometric activity measurement has been improved. Kinetic constants, K M , and v max , obtained from parallel isothermal titration calorimetric (ITC) measurements on natural and starch azure revealed, that the blue starch derivative does not differ significantly from its natural counterpart from kinetic point of view. Interestingly, substrate inhibition was observed in starch azure hydrolysis characterised by dissociation constants 49 mg/mL and 16.4 mg/mL for HSA and PPA, respectively. In this work a new protocol has been suggested for α-amylase activity measurement using boiled insoluble starch azure as substrate at 5 mg/mL concentration. Copyright © 2017 Elsevier Ltd.

    To evaluate decolorization and detoxification of Azure B dye by a newly isolated Bacillus sp. MZS10 strain, the cultivation medium and decolorization mechanism of the isolate were investigated. The decolorization was discovered to be dependent on cell density of the isolate and reached 93.55% (0.04 g/L) after 14 hr of cultivation in a 5 L stirred-tank fermenter at 2.0 g/L yeast extract and 6.0 g/L soluble starch and a small amount of mineral salts. The decolorization metabolites were identified with ultra performance liquid chromatography-tandem mass spectroscopy (UPLC-MS). A mechanism for decolorization of Azure B was proposed as follows: the C=N in Azure B was initially reduced to -NH by nicotinamide adenine dinucleotide phosphate (NADPH)-dependent quinone dehydrogenase, and then the -NH further combined with -OH derived from glucose to form a stable and colorless compound through a dehydration reaction. The phytotoxicity was evaluated for both Azure B and its related derivatives produced by Bacillus sp. MZS10 decolorization, indicating that the decolorization metabolites were less toxic than original dye. The decolorization efficiency and mechanism shown by Bacillus sp. MZS10 provided insight on its potential application for the bioremediation of the dye Azure B. Copyright © 2014 The Research Centre for Eco-Environmental Sciences, Chinese Academy of Sciences.

  6. Re-caching by Western scrub-jays (Aphelocoma californica cannot be attributed to stress.

    Directory of Open Access Journals (Sweden)

    James M Thom

    Full Text Available Western scrub-jays (Aphelocoma californica live double lives, storing food for the future while raiding the stores of other birds. One tactic scrub-jays employ to protect stores is "re-caching"-relocating caches out of sight of would-be thieves. Recent computational modelling work suggests that re-caching might be mediated not by complex cognition, but by a combination of memory failure and stress. The "Stress Model" asserts that re-caching is a manifestation of a general drive to cache, rather than a desire to protect existing stores. Here, we present evidence strongly contradicting the central assumption of these models: that stress drives caching, irrespective of social context. In Experiment (i, we replicate the finding that scrub-jays preferentially relocate food they were watched hiding. In Experiment (ii we find no evidence that stress increases caching. In light of our results, we argue that the Stress Model cannot account for scrub-jay re-caching.

  7. High fidelity--no evidence for extra-pair paternity in Siberian jays (Perisoreus infaustus.

    Directory of Open Access Journals (Sweden)

    Phillip Gienapp

    Full Text Available Extra-pair paternity (EPP in birds is related to a number of ecological and social factors. For example, it has been found to be positively related with breeding density, negatively with the amount of paternal care and especially high rates have been observed in group-living species. Siberian jays (Perisoreous infaustus breed at low densities and have extended parental care, which leads to the expectation of low rates of EPP. On the other hand, Siberian jays live in groups which can include also unrelated individuals, and provide opportunities for extra-pair matings. To assess the potential occurrence of EPP in Siberian jays, we analysed a large data pool (n=1029 offspring covering ca. 30 years of samples from a Finnish Siberian jay population. Paternities were assigned based on up to 21 polymorphic microsatellite markers with the additional information from field observations. We were unable to find any evidence for occurrence of EPP in this species. Our findings are in line with earlier studies and confirm the generally low rates of EPP in related Corvid species. These results suggest that ecological factors may be more important than social factors (group living in determining costs and benefits of extra-pair paternity.

    Metacognitive processes during memory retrieval can be tested by examining whether or not animals can assess their knowledge state when they are faced with a memory test. In a typical foraging task, food is hidden in one of the multiple tubes and the subjects are given an opportunity to check the contents of the tubes before choosing the one that they thought contained food. Following the findings from our previous study that western scrub-jays (Aphelocoma californica) can make prospective metacognition judgements, this study tested the scrub-jays' concurrent metacognition judgements. In a series of experiments, uncertainty about the food location was induced in three ways: by making the baiting process visibly unavailable, by inserting a delay between the baiting and food retrieval, and by moving the location of the bait. The jays looked into the tubes more often during the conditions that were consistent with high uncertainty. In addition, their looking behaviour was associated not with the sight of food but with information about the location of the food. These findings suggest that the jays can differentiate the states of knowing and not knowing about certain information and take appropriate action to complement their missing knowledge.

  12. A comparison of melanin bleaching and azure blue counterstaining in the immunohistochemical diagnosis of malignant melanoma.

    Distinguishing heavily pigmented melanocytes from melanophages on routine hematoxylin and eosin slides can be difficult. Melanin bleaching with potassium permanganate solution is a traditional means of removing melanin from tissues and can be used before immunohistochemical staining to remove any pigment that might be confused with the brown chromogen diaminobenzidine. Azure B stains melanin granules green-blue, easily contrasts with diaminobenzidine, and may be used as a counterstain on unbleached sections after immunohistochemical staining. To our knowledge, studies comparing melanin bleaching with azure B counterstaining in the immunohistochemical evaluation of malignant melanomas have not been performed. Paraffin sections from 33 heavily pigmented malignant melanomas were bleached with a 3.0-g/L potassium permanganate solution, immunohistochemically stained for S-100 and HMB-45, and counterstained with hematoxylin. Unbleached sections were similarly stained for S-100 and HMB-45 and counterstained with azure B. To establish optimal permanganate concentrations, a variable number of sections were bleached with lower permanganate concentrations ranging from 0.125 to 2.5 g/L. S-100 antigenicity was preserved at all permanganate concentrations, whereas HMB-45 antigenicity was abolished at concentrations of 0.5 g/L and greater. At permanganate concentrations from 0.125 to 0.5 g/L, both antigenicities were preserved; however, melanin was incompletely removed. Complications of bleaching included tissue damage and loss of cytologic detail. Positive immunohistochemical staining was observed in azure B counterstained sections. Azure B stained melanin greenblue and was easily distinguished from the brown diaminobenzidine chromogen, regardless of the antibody tested. Neither tissue damage nor loss of cytologic detail was observed. We conclude that the use of azure B counterstaining is superior to permanganate bleaching in the histologic evaluation of heavily pigmented

    Full Text Available A new simple and selective spectrophotometric method is developed for the determination of dimethoate by using Azure-B is described. The method was based on the alkaline hydrolysis of dimethoate in presence of sodium ethoxide to form sodium dimethyl dithiophosphate (Na-DMDTP. The Na-DMDTP was formed as an ion-pair complex with cationic dye, azure-B. The ion-pair complex was extracted into chloroform. The color of the organic layer was measured at 535 nm. The method was applied to the determination of dimethoate residues in water, grain and soil samples.

    Methylene blue (MB) has been shown to act at multiple cellular and molecular targets and as a result possesses diverse medical applications. Among these is a high potency reversible inhibition of monoamine oxidase A (MAO-A) that may, at least in part, underlie its adverse effects but also its psycho- and neuromodulatory actions. MB is metabolized to yield N-demethylated products of which azure B, the monodemethyl species, is the major metabolite. Similar to MB, azure B also displays a variety of biological activities and may therefore contribute to the pharmacological profile of MB. Based on these observations, the present study examines the interactions of azure B with recombinant human MAO-A and -B. The results show that azure B is a potent MAO-A inhibitor (IC₅₀=11 nM), approximately 6-fold more potent than is MB (IC₅₀=70 nM) under identical conditions. Measurements of the time-dependency of inhibition suggest that the interaction of azure B with MAO-A is reversible. Azure B also reversibly inhibits the MAO-B isozyme with an IC₅₀ value of 968 nM. These results suggest that azure B may be a hitherto under recognized contributor to the pharmacology and toxicology of MB by blocking central and peripheral MAO-A activity and as such needs to be considered during its use in humans and animals.

    In this work, the electrochemical degradation of the dye azure B in aqueous solutions was studied by electrochemical advanced oxidation processes (EAOPs), electro-Fenton, and anodic oxidation processes, using Pt/carbon-felt and boron-doped diamond (BDD)/carbon-felt cells with H₂O₂ electrogeneration. The higher oxidation power of the electro-Fenton (EF) process using BDD anode was demonstrated. The oxidative degradation of azure B by the electrochemically generated hydroxyl radicals ((•)OH) follows a pseudo-first-order kinetics. The apparent rate constants of the oxidation of azure B by (•)OH were measured according to pseudo-first-order kinetic model. The absolute rate constant of azure B hydroxylation reaction was determined by competition kinetics method and found to be 1.19 × 10(9) M(-1) s(-1). It was found that the electrochemical degradation of the dye leads to the formation of aromatic by-products which are then oxidized to aliphatic carboxylic acids before their almost mineralization to CO₂ and inorganic ions (sulfate, nitrate, and ammonium). The evolution of the TOC removal and time course of short-chain carboxylic acids during treatment were also investigated.

    Müller-Walz, R; Zimmermann, H W

    1987-01-01

    We investigated the binding of azure B to DNA (calf thymus) over a wide range of concentrations of the dye (CF) and the nucleic acid (CN) using absorption spectroscopy [CF and CN represent the total concentrations of the ye (F) and the mononucleotide units (N) of the DNA, respectively]. The binding isotherms of the dye to DNA in aqueous solutions were determined. In addition, we analysed the composition of insoluble DNA/azure B precipitates that are formed in presence of an excess of azure B. These precipitates are of particular interest, because Giemsa staining is usually performed using high dye concentrations. Azure B easily forms dimers in aqueous solutions. When determining the binding isotherms, the equilibrium between free monomers and dimers must be taken into account. Therefore, we determined the dimerisation constant (Kd) of azure B from the concentration dependency of its absorption spectra in water at the standard temperature T = 298 K (25 degrees C), Kd = 6.5 X 10(3) M-1 (experimental conditions: tris buffer, pH 7.2; concentration of Na ions, CNa = 0.002 M). As the CNa value increases, the dimerisation constant rises rapidly. When the azure B concentration is very low and there is an excess of DNA, ordinary Scatchard and Langmuir isotherms are observed. Monomer dye cations are bound to DNA, these cations being in equilibrium with free monomers in the solution. In order to obtain the Scatchard binding constant (Ks) and the binding parameter (n) spectroscopically, it is necessary to determine the extinction coefficient (epsilon Fb) of the monomer bound (b) dye molecules (F) at one analytical wave number (upsilon a). The three constants can be determined simultaneously using an iterative technique that combines Scatchard isotherms and the Benesi-Hildebrand extrapolation, CN----infinity. We obtained Ks = 1.8 X 10(5) M-1 and n = 0.18 (25 degrees C; tris buffer, pH 7.2; CNa = 0.002 M). At very low dye (CF) and competitor (CNa) concentrations, only 18% of the

    Florida scrub-jays Aphelocoma coerulescens are listed as threatened under the Endangered Species Act due to loss and degradation of scrub habitat. This study concerned the development of an optimal strategy for the restoration and management of scrub habitat at Merritt Island National Wildlife Refuge, which contains one of the few remaining large populations of scrub-jays in Florida. There are documented differences in the reproductive and survival rates of scrubjays among discrete classes of scrub height (Markov models to estimate annual transition probabilities among the four scrub-height classes under three possible management actions: scrub restoration (mechanical cutting followed by burning), a prescribed burn, or no intervention. A strategy prescribing the optimal management action for management units exhibiting different proportions of scrub-height classes was derived using dynamic programming. Scrub restoration was the optimal management action only in units dominated by mixed and tall scrub, and burning tended to be the optimal action for intermediate levels of short scrub. The optimal action was to do nothing when the amount of short scrub was greater than 30%, because short scrub mostly transitions to optimal height scrub (i.e., that state with the highest demographic success of scrub-jays) in the absence of intervention. Monte Carlo simulation of the optimal policy suggested that some form of management would be required every year. We note, however, that estimates of scrub-height transition probabilities were subject to several sources of uncertainty, and so we explored the management implications of alternative sets of transition probabilities. Generally, our analysis demonstrated the difficulty of managing for a species that requires midsuccessional habitat, and suggests that innovative management tools may be needed to help ensure the persistence of scrub-jays at Merritt Island National Wildlife Refuge.

    Full Text Available Corvids (birds in the crow family are hypothesised to have a general cognitive tool-kit because they show a wide range of transferrable skills across social, physical and temporal tasks, despite differences in socioecology. However, it is unknown whether relatively asocial corvids differ from social corvids in their use of social information in the context of copying the choices of others, because only one such test has been conducted in a relatively asocial corvid. We investigated whether relatively asocial Eurasian jays (Garrulus glandarius use social information (i.e., information made available by others. Previous studies have indicated that jays attend to social context in their caching and mate provisioning behaviour; however, it is unknown whether jays copy the choices of others. We tested the jays in two different tasks varying in difficulty, where social corvid species have demonstrated social information use in both tasks. Firstly, an object-dropping task was conducted requiring objects to be dropped down a tube to release a food reward from a collapsible platform, which corvids can learn through explicit training. Only one rook and one New Caledonian crow have learned the task using social information from a demonstrator. Secondly, we tested the birds on a simple colour discrimination task, which should be easy to solve, because it has been shown that corvids can make colour discriminations. Using the same colour discrimination task in a previous study, all common ravens and carrion crows copied the demonstrator. After observing a conspecific demonstrator, none of the jays solved the object-dropping task, though all jays were subsequently able to learn to solve the task in a non-social situation through explicit training, and jays chose the demonstrated colour at chance levels. Our results suggest that social and relatively asocial corvids differ in social information use, indicating that relatively asocial species may have

    Upon submonolayer deposition of Azure A molecules onto reconstructed Au(1 1 1), two-dimensional quasi-rectangular islands are observed by low-temperature scanning tunneling microscopy. Strikingly, the 22 × √3 reconstruction with alternating hexagonal close packed (hcp) and face centered cubic (fcc) domains of the native Au(1 1 1) surface layer is found to be strongly modified underneath the self-assembled islands of Azure A molecules. The bridge-hcp-bridge-fcc-bridge period of 63 Å on clean Au(1 1 1) is expanded by about 12% and occasionally reaches even 22%. This increase of the unreconstructed fcc areas underneath the molecular islands reflects a partial lifting of the reconstruction caused by the interaction between the adsorbed molecules and the outermost Au atoms at the molecule-metal interface.

    One of the contemporary hypotheses concerning the evolution of human altruism is the cooperative breeding hypothesis (CBH) which has recently been tested in non-human primates. Using a similar paradigm, we investigated prosociality in a cooperatively breeding corvid, the azure-winged magpie. We found that the magpies delivered food to their group members at high rates, and unlike other corvids, they did so without any cues provided by others. In two control conditions, the magpies stopped participating over time, indicating that they learned to discriminate prosocial tests from controls. Azure-winged magpies are thus the first birds that experimentally show proactive prosociality. Our findings are in line with the CBH; however, additional corvid species need to be tested in this promising paradigm. © 2016 The Authors.

    We report the in situ generation of aryl diazonium cations of Azure A, a redox-active phenothiazine dye, by reaction between the corresponding aromatic aminophenyl group and sodium nitrite in 0.1 M HCl. The subsequent electrochemical reduction of these dye diazonium salts gives rise to conductive electrografted films onto screen-printed carbon (SPC) electrodes. The resulting Azure A films have a very stable and reversible electrochemical response and exhibit potent and persistent electrocatalytic behavior toward NADH oxidation. We have optimized the electrografting conditions in order to obtain SPC modified electrodes with high and stable electrocatalytic response. The kinetic of the reaction between the NADH and the redox active centers in the Azure A film has been characterized using cyclic voltammetry and single step chronoamperometry. The catalytic currents were proportional to the concentration of NADH giving rise to linear calibration plots up to a concentration of 0.5 mM with a detection limit of 0.57±0.03 μM and a sensitivity of 9.48 A mol cm(-2) μM(-1). The precision of chronoamperometric determinations was found to be 2.3% for five replicate determinations of 3.95 μM NADH. The great stability of such modified electrodes makes them ideal for their application in the development of biosensing platforms based on dehydrogenases. Copyright © 2012 Elsevier B.V.

  14. Electrochemical behavior of Azure A/gold nanoclusters modified electrode and its application as non-enzymatic hydrogen peroxide sensor.

    Priya, C; Sivasankari, G; Narayanan, S Sriman

    2012-09-01

    A novel non-enzymatic hydrogen peroxide sensor was developed using Azure A/gold nanoclusters modified graphite electrode. The method of preparation of Azure A/gold nanoclusters was simple and it was characterized by UV-visible spectroscopy, field emission scanning electron microscopy (FESEM) and confocal Raman microscopy. The electrochemical properties of Azure A/gold nanoclusters modified graphite electrode was characterized by cyclic voltammetry. In 0.1M H(2)SO(4) the modified electrode showed redox peaks which correspond to the redox behavior of gold nanoparticle. In 0.1M PBS the modified electrode exhibited well defined redox peaks with the formal potential of -0.253 V which is analogous to the redox reaction of Azure A. The results have shown that the gold nanoclusters has reduced the formal potential of Azure A and enhanced the current due to the fast charge transfer kinetics. Also the modified electrode showed an enhanced electrocatalytic activity towards the reduction of H(2)O(2) in the concentration range of 3.26×10(-6)M to 3.2×10(-3)M with a detection limit of 1.08×10(-6)M (S/N=3). The proposed electrode exhibited good stability and reproducibility, and it has the potential application as a sensor for other biologically significant compounds. Copyright © 2012 Elsevier B.V.

    Full Text Available A model for the decomposition of azure-B by photo-Fenton reagent in the presence of ultrasound in homogeneous aqueous solution has been described. The photochemical decomposition rate of azure-B is markedly increased in the presence of ultrasound. It is a rather inexpensive reagent for wastewater treatment. The effect of different variables like the concentration of ferric ion, concentration of dye, hydrogen peroxide, pH, light intensity etc. on the reaction rate has been observed. The progress of the sono-photochemical degradation was monitored spectrophotometrically. The optimum sono-photochemical degradation conditions were experimentally determined. The results showed that the dye was completely oxidized and degraded into CO2 and H2O. A suitable tentative mechanism for sono-photochemical bleaching of azure-B by sono-photo-Fenton’s reaction has been proposed.

    The stability of Azure B and Eosin Y in stock solutions of the individual compounds as well as in mixtures of the two dyes was studied. The purpose of the study of these two essential constituents of the Romanowsky Giemsa stain, commonly used in cytology and histology, was to select a stable mixture as a definitive stock solution. Two specific high performance liquid chromatographic methods were used to monitor qualitative and quantitative changes in solutions. Several parameters influencing the stability of Azure B were examined e.g. the type of counter ion, the presence of Eosin Y and the type of solvent used. The second part focused on the stability of Eosin Y in mixtures with different cationic dyes submitted to high temperatures. In conclusion, an Azure B SCN-Eosin Y acid mixture in dimethylsulphoxide (concentrations 0.75% and 0.12%, respectively) was selected as being the most appropriate composition of a stock solution for the Romanowsky Giemsa stain.

    2007-01-01

    Several phenol derivatives were evaluated regarding their capacities for Fe(3+) and Cu(2+) reduction. Selected compounds were assayed in Fenton-like reactions to degrade Azure B. 3,4-Dihydroxyphenylacetic, 2,5-dihydroxyterephtalic, gallic, chromotropic and 3-hydroxyanthranilic acids were the most efficient reducers of both metallic ions. The reaction system composed of 3-hydroxyanthranilic acid/Fe(3+)/H(2)O(2) was able to degrade Azure B at higher levels than the conventional Fenton reaction (87% and 75% of decolorization after 20min reaction, respectively). Gallic and syringic acids, catechol and vanillin induced Azure B degradations at lower levels as compared with conventional Fenton reaction. Azure B was not degraded in the presence of 10% (v/v) methanol or ethanol, which are OH radical scavengers, confirming the participation of this radical in the degradation reactions. Iron-containing reactions consumed substantially more H(2)O(2) than reactions containing copper. In iron-containing reactions, even the systems that caused a limited degradation of the dye consumed high concentrations of H(2)O(2). On the other hand, the reactions containing Fe(3+), H(2)O(2) and 3-hydroxyanthranilic acid or 3,4-dihydroxyphenylacetic acid were the most efficient on degradation of Azure B and also presented the highest H(2)O(2) consumption. These results indicate that H(2)O(2) consumption occurs even when the dye is not extensively degraded, suggesting that part of the generated OH radicals reacts with the own phenol derivative instead of Azure B.

    2014-01-01

    In this study, we fabricated an Al/Azure A/p-Si heterojunction. The electrical characterization and photovoltaic properties of the Al/Azure A/p-Si heterojunction were investigated by current–voltage (I–V) under dark and illuminated conditions at room temperature. The photovoltaic device gives V oc  = 340 mV and I sc  = 807 μA under 30 mW cm −2 . The device was found to have a fill factor (FF) and power conversion efficiency (η P ) 36% and 4.07%, respectively. The values of some diode parameters were determined using thermionic emission theory. Some diode parameters, such as the ideality factor (n) and barrier height (ϕ b ) values, were found to be 1.26 and 0.78 eV, respectively. An ideality factor higher than 1 can be explained on the basis of the inhomogeneity barrier-height model or as a result of natural oxide layers. The results obtained from electrical and photovoltaic properties show that the device can be used as photodiode and in opto-electronic circuit applications. (paper)

    In the present work, isomerization, photophysical properties and heat conductivity of the substance Azure A chloride (AZAC): 3-amino-7-(dimethlamino)phenothiazin-5-ium chloride under the action of UV radiation in the presence of polyvinyl alcohol (PVA) matrix was studied using the Hartree-Fock (HF) and Density Functional Theory (DFT) methods. The electronic absorption spectra of AZAC in dimethylformamide (DMF) solution and in aqueous medium before and after UV radiation were calculated. The nature of absorption bands of AZAC and its tautomeric prototropic form with the transfer of the electron (AZAC1) in the visible and near UV spectral regions was interpreted. The solvent effect on the absorption spectrum of the AZAC has established. The comparison of measured FTIR, UV-Visible data allowed assignments of major special features of title molecules. The frontier molecular orbital HOMO-LUMO have been also presented that shows the charge transfer interactions taking place within these molecules. The excitation energies for both molecules AZAC and AZAC1 have also been calculated. The experimental as well as theoretical investigations of azure molecule have a close agreement and it gives other important clues about the properties of the system. Anisotropy of thermal conductivity in PVA-films containing AZAC and AZAC1 were also measured.

    The present study investigates the dependence of photocatalytic rate on molecular structure of the substrate that is degraded. The photocatalytic degradation of Azure (A and B) and Sudan (III and IV) dyes, having similar structure, but different functional groups, were investigated with two catalysts. The photocatalytic activity of solution combustion synthesized TiO 2 (CS TiO 2 ) was compared with that of Degussa P-25 for degrading these dyes. The effect of solvents and mixed-solvent system on photodegradation of Sudan III was investigated. The photodegradation rate was found to be higher in solvents with higher polarity. The effect of pH and the presence of metal ions in the form of chloride and nitrate salt, on degradation rate of Azure A was also investigated. The metal ions significantly reduced the photocatalysis rates. A detailed Langmuir-Hinshelwood kinetic model has been developed to explain the effect of metal ions on degradation rate of the substrate. This model elucidates the contribution of holes and electrons towards degradation of the dye

    Chitin and its derivatives are widely used as biomedical materials because of their versatility and biocompatibility. Chitinases are enzymes that produce chito-oligosaccharides from chitin. The assay of chitinase activity is difficult because few appropriate substrates are available. In this study, the authors developed an efficient and low-cost chitinase assay using colloidal chitin azure. The assay feasibility is evaluated and compared with traditional assays employing colloidal chitin and chitin azure. The authors found that the optimum pH for determining chitinase activity using colloid chitin azure was pH 5 or 8. The method was sensitive, and the assay was complete within 30 min. When the assay was used to measure chitinase activities produced by 2 strains of chitinolytic bacteria, BCTS (an Escherichia coli BL21 [DE3] expressing a secretory recombinant chitinase) and AS1 (a chitinolytic bacterium with low levels of chitinase), it was shown that cultivation in Bushnell-Haas selection medium caused AS1 to secrete a higher level of chitinase than was secreted when the bacterium grew in other media. In summary, colloid chitin azure is a sensitive, feasible, reproducible, and low-cost substrate for the assay of chitinase activity.

    Azure B is the most important Romanowsky dye. In combination with eosin Y it produces the well known Romanowsky-Giemsa staining pattern on the cell. Usually commercial azure B is strongly contaminated. We prepared a sample of azure B-BF4 which was analytically pure and had no coloured impurities. The substance was used to redetermine the molar extinction coefficient epsilon (v)M of monomeric azur B in alcoholic solution. In the maximum of the long wavelength absorption at v = 15.61 kK (lambda = 641 nm) the absorptivity is epsilon (15.61)M = (9.40 +/- 0.15) x 10(4)M-1 cm-1. This extinction coefficient may be used for standardization of dye samples. In aqeuous solution azur B forms dimers and even higher polymers with increasing concentration. The dissociation constant of the dimers, K = 2,2 x 10(-4)M (293 K), and the absorption spectra of pure monomers and dimers in water have been calculated from the concentration dependence of the spectra using an iterative procedure. The molar extinction coefficient of the monomers at 15.47 kK (646 nm) is epsilon (15.47)M = 7.4 x 10(4)M-1 cm-1. The dimers have two long wavelength absorption bands at 14.60 and 16.80 kK (685 and 595 nm) with very different intensities 2 x 10(4) and 13.5 x 10(4)M-1 cm-1. The spectrum of the dimers in aqueous solution is in agreement with theoretical considerations of Förster (1946) and Levinson et al. (1957). It agrees with an antiparallel orientation of the molecules in the dimers. It may be that dimers bound to a substrate in the cell have another geometry than dimers in solution. In this case the weak long wavelength absorption of the dimers can increase.

    The phenothiazinium compound, methylene blue (MB), possesses diverse pharmacological actions and is attracting attention for the treatment of bipolar disorder and Alzheimer's disease. MB acts on both monoamine oxidase (MAO) and the nitric oxide (NO)-cGMP pathway, and possesses antidepressant activity in rodents. The goal of this study was to synthesise a structural analogue of MB, ethylthioninium chloride (ETC), and to evaluate the effects of the structural changes on the MAO inhibitory and antidepressant properties of MB. This study also investigated the antidepressant properties of azure B, the major metabolite of MB, versus MB and imipramine as active comparators. ETC and azure B were firstly evaluated as inhibitors of human MAO, and secondly for antidepressant-like activity in the acute forced swim test (FST) in rats, and compared to saline, imipramine and MB. The results document that ETC is a reversible inhibitor of MAO-A and MAO-B with IC50 values of 0.510 μM and 0.592 μM, respectively, and that it is a weaker MAO-A inhibitor than MB and azure B. ETC and azure B were more effective than imipramine and MB in reversing immobility in the FST without inducing locomotor effects, with evidence supporting a serotonergic action. Of interest is the finding that ETC is more toxic for cultured cells than MB. Azure B may therefore be a contributor to the antidepressant effect of MB. Small structural changes made to MB retain its antidepressant effect, even though the resulting phenothiazinium compound possesses reduced MAO-A inhibitory potency.

    State-attribution is the ability to ascribe to others an internal life like one's own and to understand that internal, psychological states such as desire, hope, belief, and knowledge underlie others' actions. Despite extensive research, comparative studies struggle to adequately integrate key factors of state-attribution that have been identified by evolutionary and developmental psychology as well as research on empathy. Here, we develop a behavioral paradigm to address these issues and investigate whether male Eurasian jays respond to the changing desire-state of their female partners when sharing food. We demonstrate that males feed their mates flexibly according to the female's current food preference. Critically, we show that the males need to see what the female has previously eaten to know what food she will currently want. Consequently, the males' sharing pattern was not simply a response to their mate's behavior indicating her preference as to what he should share, nor was it a response to the males' own desire-state. Our results raise the possibility that these birds may be capable of ascribing desire to their mates.

  12. Stephen Jay Gould and the Value of Neutrality of Science During the Cold War.

    2016-12-01

    Stephen Jay Gould was a paleontologist and scientific celebrity at the close of the twentieth century, most famous for his popular writings on evolution and his role in the American creationist controversies of that era. In the early 1980s, Gould was drawn into the "nuclear winter" episode through his friendship with Carl Sagan, an astronomer and popular science celebrity. Sagan helped develop the theory of nuclear winter and subsequently used the theory as evidence to petition the United States government to scale back its nuclear armament. The theory of nuclear winter claimed that even a small nuclear exchange could result in a atmospheric blackening akin to the extinction event of the late Cretaceous. Gould was not a climate scientist but he testified before the U.S. House of Representatives as an expert on historical extinction events. Gould's insistence on the value-neutrality of nuclear winter reveals much about the moral politics of science in late Cold War America. Coming at the heels of leftist scientific activism of the 1980s, the nuclear winter episode demonstrates how value-neutrality emerged the salient feature of scientific involvement in American politics in this period.

    Synthetic seismograms generated by solving the seismic wave equation using numerical methods are being widely used in seismology. For fully three-dimensional seismic structure models, the generation of these synthetic seismograms may require large amount of computing resources. Conventional high-performance computer clusters may not provide a cost-effective solution to this type of applications. The newly emerging cloud-computing platform provides an alternative solution. In this paper, we describe our implementation of a synthetic seismogram generator based on the reciprocity principle using the Windows Azure cloud application framework. Our preliminary experiment shows that our cloud-based synthetic seismogram generator provides a cost-effective and numerically efficient approach for computing synthetic seismograms based on the reciprocity principle.

  14. A new assay for lignin-type peroxidases employing the dye azure B.

    1992-01-01

    The discovery in 1983 of fungal "ligninases" capable of catalyzing the peroxidation of nonphenolic aromatic lignin components has been seen as a major advance in understanding how certain basidiomycete fungi can completely degrade lignin. The ability of these lignin-type peroxidases to covert millimolar concentrations of veratryl alcohol to veratraldehyde, indicated by a change in the A310 of veratraldehyde, has become the standard assay for routine quantitation of LP activity. A new assay based on the oxidation of micromolar concentrations of the dye Azure B is presented. Although it is as simple and rapid as the veratryl alcohol assay, it appears to overcome some of the shortcomings of that assay. In particular, interference from UV- and short-wavelength visible-light-absorbing materials is greatly reduced and assay specificity is improved. PMID:1444425

  17. Stephen Jay Kline on systems, or physics, complex systems, and the gap between.

    Campbell, Philip LaRoche

    2011-06-01

    At the end of his life, Stephen Jay Kline, longtime professor of mechanical engineering at Stanford University, completed a book on how to address complex systems. The title of the book is 'Conceptual Foundations of Multi-Disciplinary Thinking' (1995), but the topic of the book is systems. Kline first establishes certain limits that are characteristic of our conscious minds. Kline then establishes a complexity measure for systems and uses that complexity measure to develop a hierarchy of systems. Kline then argues that our minds, due to their characteristic limitations, are unable to model the complex systems in that hierarchy. Computers are of no help to us here. Our attempts at modeling these complex systems are based on the way we successfully model some simple systems, in particular, 'inert, naturally-occurring' objects and processes, such as what is the focus of physics. But complex systems overwhelm such attempts. As a result, the best we can do in working with these complex systems is to use a heuristic, what Kline calls the 'Guideline for Complex Systems.' Kline documents the problems that have developed due to 'oversimple' system models and from the inappropriate application of a system model from one domain to another. One prominent such problem is the Procrustean attempt to make the disciplines that deal with complex systems be 'physics-like.' Physics deals with simple systems, not complex ones, using Kline's complexity measure. The models that physics has developed are inappropriate for complex systems. Kline documents a number of the wasteful and dangerous fallacies of this type.

    The Tailed Jay Graphium agamemnon is one of the attractive papilionid butterflies that enliven the environment of Visakhapatnam. It occurs throughout the year. It lays eggs singly on young leaves of the mast tree Polyalthia longifolia var. pendula (Annonaceae). The eggs take 3-4 days to hatch. The larvae go through 5 instars over a period of 15-16 days. The pupal period is 13-14 days. The total period from egg to adult emergence spans over 33-36 days. Based on this short life cycle, and larval and pupal development success studied every month, this butterfly can be multivoltine with a minimum of 7-8 broods in a year. Both CI and GR decreased with the age of larva, their average figures being 3.78 and 0.43 respectively. AD values are high (average 92%) and decreased through successive instars. Both ECD and ECI followed a similar pattern with an increase from instar I up to II, then a decrease up to IV and again an increase in instar V and the highest value is with fifth instar. Adults frequently visited flowers (12-35 flowers in a min) spending 1.0 to 3.2 seconds on a flower. The nectar concentration ranged between 16 and 58%. Peak foraging activity mostly fell between 0900-1000 h. The proboscis received pollen in most of the floral species visited, thus satisfying one of the characteristics of butterfly pollination. Being a fast and strong flier it is treated as "high energy" pollinator promoting cross-pollination.

    The fracture impact of adjuvant bisphosphonates in breast cancer is not defined with most trials reporting changes in bone mineral density as a surrogate. The AZURE trial (ISRCTN79831382) evaluated the impact of adjuvant zoledronic acid (ZOL) on fractures. The AZURE trial is an academic, multi-centre, randomised phase III study evaluating the addition of ZOL 4 mg to standard therapy (neo/adjuvant chemotherapy and/or endocrine therapy) for 5 years (administered by intravenous (iv) infusion every 3-4 weeks for 6 doses, then 3 monthly × 8 and 6 monthly × 5) in patients with stage II/III early breast cancer. Fracture data collected as part of skeletal-related adverse event reporting were analysed after a median of 84.2 months of follow-up and 966 disease-free survival (DFS) events. We assessed number of fractures, time-to-first fracture and the incidence of fractures before and after disease recurrence. Two hundred forty-four patients reported ≥1 fracture, 140 (8.3%) in the control arm (171 fractures) and 104 (6.2%) in the ZOL arm (120 fractures). Of the 291 fractures reported, 207 fractures occurred in the absence of recurrence (control 111, ZOL 96), 80 after recurrence (control 59, ZOL 21). The 5-year fracture rate was reduced from 5.9% (95%CI 4.8, 7.1%; control) to 3.8% (95%CI 2.9, 4.7%) with ZOL. ZOL significantly increased time-to-first fracture (HR 0.69, 95%CI 0.53-0.90; P = 0.0053) but the majority of fracture prevention benefit occurred after a DFS event (HR 0.3; 95%CI 0.17, 0.53; P < 0.001). Fracture benefits from ZOL were similar across menopausal sub-groups. In conclusion, adjuvant ZOL reduced the risk of clinical fractures, the majority of this protection occurred after disease recurrence. Copyright © 2018 Elsevier Ltd. All rights reserved.

    2012-01-01

    The degradation of azure B dye (C15H16ClN3S; AB) has been studied by Fenton, sonolysis and sono-electroFenton processes employing ultrasound at 23 kHz and the electrogeneration of H2O2 at the reticulated vitreous carbon electrode. It was found that the dye degradation followed apparent first-order kinetics in all the degradation processes tested. The rate constant was affected by both the pH of the solution and initial concentration of Fe2+, with the highest degradation obtained at pH between 2.6 and 3. The first-order rate constant decreased in the following order: sono-electroFenton>Fenton>sonolysis. The rate constant for AB degradation by sono-electroFenton is ∼10-fold that of sonolysis and ∼2-fold the one obtained by Fenton under silent conditions. The chemical oxygen demand was abated ∼68% and ∼85% by Fenton and sono-electroFenton respectively, achieving AB concentration removal over 90% with both processes. Copyright © 2011 Elsevier B.V.

    The identity of Celastrina species in eastern Canada is reviewed based on larval host plants, phenology, adult phenotypes, mtDNA barcodes and re-assessment of published data. The status of the Cherry Gall Azure (Celastrina serotina Pavulaan & Wright) as a distinct species in Canada is not supported by any dataset, and is removed from the Canadian fauna. Previous records of this taxon are re-identified as Celastrina lucia (Kirby) and Celastrina neglecta (Edwards). Evidence is presented that both Celastrina lucia and Celastrina neglecta have a second, summer-flying generation in parts of Canada. The summer generation of Celastrina lucia has previously been misidentified as Celastrina neglecta, which differs in phenology, adult phenotype and larval hosts from summer Celastrina lucia. DNA barcodes are highly conserved among at least three North American Celastrina species, and provide no taxonomic information. Celastrina neglecta has a Canadian distribution restricted to southern Ontario, Manitoba, Saskatchewan and easternmost Alberta. The discovery of museum specimens of Celastrina ladon (Cramer) from southernmost Ontario represents a new species for the Canadian butterfly fauna, which is in need of conservation status assessment.

    Thin films of azure B (AB) have been prepared by thermal evaporation. Structural, optical, and dielectric characteristics of as-prepared and annealed samples were studied. AB is polycrystalline in as-synthesized powder form. Detailed x-ray diffraction studies showed amorphous structure for pristine and annealed films. Fourier-transform infrared vibrational spectroscopy indicated minor changes in molecular bonds of AB thin films either after deposition or after thermal annealing. Optical transmittance and reflection spectra of prepared thin films were studied at nearly normal light incidence in the spectral range from 200 nm to 2500 nm, showing marked changes without new peaks. Annealing increased the absorption coefficient and decreased the optical bandgap. Onset and optical energy gaps of pristine films were found to obey indirect allowed transition with values of 1.10 eV and 2.64 eV, respectively. Annealing decreased the onset and optical energy gaps to 1.0 eV and 2.57 eV, respectively. The dispersion parameters before and after annealing are discussed in terms of a single-oscillator model. The spectra of the dielectric constants ( ɛ 1, ɛ 2) were found to depend on the annealing temperature in addition to the incident photon energy.

    Full Text Available In the present paper, we describe the results of electrical characterization of AZUR SPACE triple-junction solar cells at a sun light intensity of 3.7% AM0 and temperatures down to −150°C. At these conditions, which are relevant for the anticipated ESA JUICE mission, the cell efficiency reaches 33.5 % at BOL. Special attention has been paid to the establishing of an in-situ characterization procedure for defining EOL cell characteristics after electron and proton irradiation at low temperature low intensity condition. It was shown that solar cells irradiated at low temperature exhibit a strong recovery effect within short time after stopping the irradiation whereas the absolute value of the recovery depends on the irradiation fluence and particle type. Further on, it was demonstrated that the degradation of the maximum power, Pmp, is much stronger than the degradation of Isc and Voc values. Experimentally defined remaining factors for electron and proton irradiation and the quantification of the observed recovery effects allow a realistic prediction of the solar cell performance at JUICE mission conditions and are essential for the planned solar cell qualification activities.

    To analyze and compare survival of patients initially treated with peritoneal dialysis (PD) or hemodialysis (HD). We used data from the French REIN registry. We included all patients aged 18 years or more who started dialysis between 1st January 2004 and 12 December 2012 in Provence-Alpes-Côte d'Azur Region (PACA). These patients were followed up until 30 June 2014. Survival curves were generated using the Kaplan-Meier technique and tested using the log-rank test. Variables predictive of all-cause mortality were determined using Cox regression models. The propensity score was used. Survival was similar between initial dialysis modalities: PD and HD, even after adjusting for the propensity score. But, when we exclude the patients who had switched from one technique of dialysis to another, survival was better in HD patients. According to the multivariate analysis, advanced age and the lack of walking autonomy appear to be associated with an increase in mortality in dialysis patients. But, the presence of hypertension improve the survival in this cohort. The survival is similar between hemodialysis and peritoneal dialysis. Copyright © 2016 Association Société de néphrologie.

    The Florida Scrub-Jay (Aphelocoma coerulescens) is an indicator of ecosystem integrity of Florida scrub, an endangered ecosystem that requires frequent fire. One of the largest populations of this federally threatened species occurs on John F. Kennedy Space Center/Merritt Island National Wildlife Refuge. Population trends were predicted using population modeling and field data on reproduction and survival of Florida Scrub-Jays collected from 1988 - 1995. Analyses of historical photography indicated that habitat suitability has been declining for 30 years. Field data and computer simulations suggested that the population declined by at least 40% and will decline by another 40% in 1 0 years, if habitat management is not greatly intensified. Data and computer simulations suggest that habitat suitability cannot deviate greatly from optimal for the jay population to persist. Landscape trajectories of vegetation structure, responsible for declining habitat suitability, are associated with the disruption of natural fire regimes. Prescribed fire alone can not reverse the trajectories. A recovery strategy was developed, based on studies of Florida Scrub-Jays and scrub vegetation. A reserve design was formulated based on conservation science principles for scrub ecosystems. The strategy emphasizes frequent fire to restore habitat, but includes mechanical tree cutting for severely degraded areas. Pine thinning across large areas can produce rapid increases in habitat quality. Site-specific strategies will need to be developed, monitored, and modified to achieve conditions suitable for population persistence.

    Decisions often involve outcomes that will not materialise until later, and choices between immediate gratification and future consequences are thought to be important for human health and welfare. Combined human and animal research has identified impulsive intertemporal choice as an important factor in drug-taking and pathological gambling. In this paper, we give an overview of recent research into intertemporal choice in non-human animals, and argue that this work could offer insight into human behaviour through the development of animal models. As an example, we discuss the role of future-thinking in intertemporal choice, and review the case for the Western scrub-jay (Aphelocoma californica) as an animal model of such prospective cognition.

    A simple, sensitive and selective non-enzymatic glucose sensor was constructed in this paper. The poly(azure A)-nickel modified glassy carbon electrode was successfully fabricated by the electropolymerization of azure A and the adsorption of Ni(2+). The Ni modified electrode, which was characterized by scanning electron microscope, cyclic voltammetry, electrochemical impedance spectra and X-ray photoelectron spectroscopy measurements, respectively, displayed well-defined current responses of the Ni(III)/Ni(II) couple and showed a good activity for electrocatalytic oxidation of glucose in alkaline medium. Under the optimized conditions, the developed sensor exhibited a broad linear calibration range of 5 μM-12mM for quantification of glucose and a low detection limit of 0.64μM (3σ). The excellent analytical performance including simple structure, fast response time, good anti-interference ability, satisfying stability and reliable reproducibility were also found from the proposed amperometric sensor. The results were satisfactory for the determination of glucose in human serum samples as comparison to those from a local hospital. Copyright © 2016 Elsevier B.V. All rights reserved.

    We present the characterizations of thermally induced third-order nonlinearity, optical power limiting and self-induced diffraction rings in Azure B dye. Nonlinear measurements were carried out by employing the single beam z-scan technique. He-Ne laser operating in continuous wave mode at 633 nm wavelength was used as the source of excitation. Azure B possesses self-defocusing type of nonlinearity. Self-diffraction rings pattern were observed due to thermal lensing and change in the refractive index. Nonlinear absorption process in Azure B was due to the reverse saturable absorption. The nonlinear refractive index n2, the nonlinear absorption coefficient βeff and the third-order optical susceptibility χ(3) were found to be of the order 10-5 esu, 10-2 cm/W and 10-7 esu respectively. Azure B also displays good optical power handling capability of laser beam at the experimental wavelength, indicating the possible photonics device application such as all-optical power limiting.

    Evaluation of cutaneous pigmented lesions can be diagnostically challenging and represents an activity often supplemented by immunohistochemistry. Immunohistochemical studies typically employ 3,3'-diaminobenzidine (DAB) resulting in brown staining of both melanocytes and melanin. Difficulty may thus arise in distinguishing different cell types in heavily melanized lesions. Azure blue counterstaining has been used in conjunction with melanoma antigen recognized by T-cells (MART-1) to differentiate melanocytes from melanin by highlighting the latter blue-green. Microphthalmia transcription factor (MiTF) represents an alternative immunomarker that shows nuclear reactivity, which facilitates ease of interpretation. Twenty examples of solar lentigo and melanoma in situ (MIS) were independently evaluated utilizing MiTF and MART-1/Azure blue for melanocyte quantification. Melanocyte counts were averaged over five high-power fields (×400) to obtain a mean melanocytic count. There was no significant difference in the mean melanocytic count between MART-1/Azure blue and MiTF as assessed in the solar lentigo group and as assessed independently in the MIS group. MiTF nuclear staining facilitated interpretation and required less laboratory preparation, as an additional counterstain was not necessary. MiTF is as effective as MART-1/Azure blue in identifying melanocytes in the context of solar lentigo or MIS. On the basis of our results, we favor expanding the use of MiTF as an immunohistochemical marker, as it provides an efficient alternative to MART-1 with Azure blue counterstaining in the evaluation of cutaneous pigmented lesions.

    When observed by a conspecific, food-caching Western scrub-jays employ a number of different strategies to protect their caches from theft, for example by caching in visually inaccessible locations or re-caching more of those items that the observer could see being cached (Dally, Emery, & Clayton, 2004, 2005; Emery & Clayton, 2001). These findings suggest higher social cognitive abilities in these animals (Clayton, Dally, & Emery, 2007; Clayton, 2014). The present study aimed to determine whe...

    2000-12-01

    We used tetra-nucleotide microsatellite DNA typing to estimate the frequency of extrapair fertilization (EPF) in a plural breeding species, the Mexican jay, Aphelocoma ultramarina, in Arizona. We found EPF in 32 of 51 complete broods (63%) and 55 of 139 nestlings (40%) for which the putative father had been identified (one of the highest rates of EPF known for birds). At least 96.1% of EPF fathers came from within the group. This is by far the highest known within-group EPF rate among socially monogamous, communally rearing species. Most (70%) males of breeding age (3+ years) had no genetic paternity in a given year. Social fathers (i.e. those with nests and mated females) rarely obtained EPFs; of 25 social fathers, 23 had young in only one nest and only two had young in two nests by virtue of EPF. Of the 27 males known to be EPF fathers without a nest of their own, none had young in more than one nest. Only 7% of EPF fathers had their own broods reaching banding age (day 14), compared with 29.7% of social fathers. The proportion of EPF young was significantly larger in smaller broods. Breeding females in all age classes were equally likely to have EPF young. Copyright 2000 The Association for the Study of Animal Behaviour.

  17. California scrub-jays reduce visual cues available to potential pilferers by matching food colour to caching substrate.

    Some animals hide food to consume later; however, these caches are susceptible to theft by conspecifics and heterospecifics. Caching animals can use protective strategies to minimize sensory cues available to potential pilferers, such as caching in shaded areas and in quiet substrate. Background matching (where object patterning matches the visual background) is commonly seen in prey animals to reduce conspicuousness, and caching animals may also use this tactic to hide caches, for example, by hiding coloured food in a similar coloured substrate. We tested whether California scrub-jays ( Aphelocoma californica ) camouflage their food in this way by offering them caching substrates that either matched or did not match the colour of food available for caching. We also determined whether this caching behaviour was sensitive to social context by allowing the birds to cache when a conspecific potential pilferer could be both heard and seen (acoustic and visual cues present), or unseen (acoustic cues only). When caching events could be both heard and seen by a potential pilferer, birds cached randomly in matching and non-matching substrates. However, they preferentially hid food in the substrate that matched the food colour when only acoustic cues were present. This is a novel cache protection strategy that also appears to be sensitive to social context. We conclude that studies of cache protection strategies should consider the perceptual capabilities of the cacher and potential pilferers. © 2017 The Author(s).

    Antioxidants play key roles in preventing free radical damage to various molecules, cells, and tissues, but it is not well understood how variation in antioxidant levels may relate to the reproductive success or health of wild animals. We explored the relationship between circulating antioxidant concentrations and both body condition and timing of reproduction in male and female Florida Scrub-Jays (Aphelocoma coerulescens), a cooperatively breeding passerine bird. We examined whether levels of uric acid, vitamin E, and carotenoids (all potentially important antioxidants) were linked to body condition and timing of reproduction, two measures that are directly related to reproductive success. Antioxidant concentrations were not correlated with body condition, but they were related to timing of first clutch initiation, though not always in the predicted direction. Elevated circulating levels of carotenoids were associated with delayed clutch initiation in female breeders. Relatively higher vitamin E levels in control birds were associated with earlier clutch initiation, whereas male breeders that received long-term food supplementation had elevated levels of vitamin E and delayed reproduction. Several potential explanations for the link between elevated levels of antioxidants and delayed clutch initiation are discussed. Separate explanations for each sex include, but are not limited to, oxidative stress as a result of territory defense efforts in males, different dietary regimes due to supplementation, and mobilized plasma antioxidants in females that were coping with a stressor. © 2010 Wiley-Liss, Inc.

    The Romanowsky-Giemsa staining (RG staining) has been studied by means of microspectrophotometry using various staining conditions. As cell material we employed in our model experiments mouse fibroblasts, LM cells. They show a distinct Romanowsky-Giemsa staining pattern. The RG staining was performed with the chemical pure dye stuffs azure B and eosin Y. In addition we stained the cells separately with azure B or eosin Y. Staining parameters were pH value, dye concentration, staining time etc. Besides normal LM cells we also studied cells after RNA or DNA digestion. The spectra of the various cell species were measured with a self constructed microspectrophotometer by photon counting technique. The optical ray pass and the diagramm of electronics are briefly discussed. The nucleus of RG stained LM cells, pH congruent to 7, is purple, the cytoplasm blue. After DNA or RNA digestion the purple respectively blue coloration in the nucleus or the cytoplasm completely disappeares. Therefore DNA and RNA are the preferentially stained biological substrates. In the spectrum of RG stained nuclei, pH congruent to 7, three absorption bands are distinguishable: They are A1 (15400 cm-1, 649 nm), A2 (16800 cm-1, 595 nm) the absorption bands of DNA-bound monomers and dimers of azure B and RB (18100 cm-1, 552 nm) the distinct intense Romanowsky band. Our extensive experimental material shows clearly that RB is produced by a complex of DNA, higher polymers of azure B (degree of association p greater than 2) and eosin Y. The complex is primarily held together by electrostatic interaction: inding of polymer azure B cations to the polyanion DNA generates positively charged binding sites in the DNA-azure B complex which are subsequently occupied by eosin Y anions. It can be spectroscopically shown that the electronic states of the azure B polymers and the attached eosin Y interact. By this interaction the absorption of eosin Y is red shifted and of the azure B polymers blue shifted. The

    After incorporation into a polyacrylamide matrix, the biopolymers DNA, RNA, heparin, hyaluronic acid, collagen and the synthetic polymers poly(U) and poly(A, U) were stained with the pure thiazine dyes, Methylene Blue, the Azures and Thionin alone and combined with Eosin Y. Satisfactory spectrophotometric agreement was obtained between the staining reactions of the biopolymers in the artificial matrix and those in their natural surroundings. This was especially true with respect to the specificity of the Azure B-Eosin Y dye-pair, which is based on the generation, on suitable substrates, of a purple colour, the Romanowsky-Giemsa effect (RGE), with an absorbance maximum near 550 nm. In the model experiments, DNA, heparin, hyaluronic acid and collagen were found to be RGE-positive and poly(U), poly(A, U) and RNA RGE-negative. A theory of RGE is proposed which complies with the new and earlier observations: after saturation of available anionic binding sites and aggregate formation by Azure B, electron donor acceptor complexes are formed between Eosin Y and Azure B via hydrogen-bridge formation of the aminosubstituent proton of Azure B and between Eosin Y and the biopolymer surface. Charge-transfer complex formation may also account for the qualitative identity of Azure B-Eosin Y and Azure A-Eosin Y spectra of substrates, which are coloured purple. Quantitatively, Azure A-Eosin Y is less efficient in giving RGE. The generation of RGE is time-dependent. Equilibrium staining is attained after about 120 h. The implications of the results for the biological application of Romanowsky-Giemsa staining are discussed briefly.

    Electroactive films containing redox active phenothiazine moieties are covalently bound onto gold and graphene oxide gold hybrid electrodes, using reductive redox grafting of N’,N’-dimethylphenothiazin-5-ium-3,7-diamine (Azure A) diazonium salt. The grafting procedure is based on continuous voltammetric potential sweep of solutions containing the phenothiazine diazonium salt previously generated in situ. Control of the film thickness, electroactivity and stability can easily be exerted through appropriate choice of the concentration and number of potential scans performed. Cyclic Voltammetry, Electrochemical Quartz Crystal Microbalance (EQCM) and Spectroscopic Ellipsometry are used to characterize the growth process as well as the viscoelastic properties of the resulting stable electrografted films. The electron transfer reactions through the films are mediated by the presence of the Azure A redox moieties, which show a quasi-reversible electrochemical response and exhibit a potent electrocatalytic effect toward the oxidation of NADH. This electrocatalytic model has been used to compare the properties of Azure A electrografted films generated on gold electrodes with those obtained on hybrid electrodes composed by graphene oxide modified gold electrodes

    Full Text Available The implementation of wireless sensor networks (WSNs for monitoring the complex, dynamic, and harsh environment of underground coal mines (UCMs is sought around the world to enhance safety. However, previously developed smart systems are limited to monitoring or, in a few cases, can report events. Therefore, this study introduces a reliable, efficient, and cost-effective internet of things (IoT system for air quality monitoring with newly added features of assessment and pollutant prediction. This system is comprised of sensor modules, communication protocols, and a base station, running Azure Machine Learning (AML Studio over it. Arduino-based sensor modules with eight different parameters were installed at separate locations of an operational UCM. Based on the sensed data, the proposed system assesses mine air quality in terms of the mine environment index (MEI. Principal component analysis (PCA identified CH4, CO, SO2, and H2S as the most influencing gases significantly affecting mine air quality. The results of PCA were fed into the ANN model in AML studio, which enabled the prediction of MEI. An optimum number of neurons were determined for both actual input and PCA-based input parameters. The results showed a better performance of the PCA-based ANN for MEI prediction, with R2 and RMSE values of 0.6654 and 0.2104, respectively. Therefore, the proposed Arduino and AML-based system enhances mine environmental safety by quickly assessing and predicting mine air quality.

The detection limit of the method was 0.5 ng for heparin, LMWH, HA, CSA, and DS, 2 ng for KS, and 6 ng for HA in the 2-microliter sample volume. Dilution curves demonstrated linear correlation between the logarithm of the concentration of glycosaminoglycans (GAGs) and their optical absorbance at 548 nm. The linear ranges were 1 to 500 ng/microliter for heparins, LMWHs, HS, DS, and CSA, 3 to 500 ng/microliter for KS, and 8 to 500 ng/microliter for HA. GAGs have their characteristic migration patterns and their Rf value decreased from CSA to KS, DS, HS, heparin, and HA. The differences were described for heparins and LMWHs. LMWHs migrated faster and displayed broader bands than unfractionated heparins. It was also observed that some unfractionated heparins contained low sulfated GAGs as contamination, which seemed to be DS as judged by their migration patterns.

    The azure-winged magpie (AWM), Cyanopica cyanus, is found in Asia and Iberia. This remarkable disjunct distribution has been variously explained by either the sixteenth-century introduction of birds into Iberia from the Far East, or by the loss of individuals from the central part of their range as a result of Pleistocene glaciations. We have used the mitochondrial control region to undertake a molecular phylogenetic analysis of the AWM, with sequences examined from individuals collected from across the current distribution range and incorporating representatives of all currently defined subspecies. The Western birds are genetically distinct from their Asian congeners and their divergence is basal in the phylogenetic tree. This indicates that the AWM is native to Iberia and not the result of a recent introduction from Asia. In Asia, two major mitochondrial DNA lineages were identified. These correspond to an Inland Asia group and a Pacific Seaboard group, and are separated topographically by the Da Hingan Ling mountains and the Yellow Sea. Molecular clock estimates suggest that these divergences are associated with Pleistocene glaciations. Furthermore, our data do not support the current classification of the AWM into 10 subspecies, as defined based on morphology and geographical distribution.

    Oxazinium derivatives have recently played an important role in bioanalysis attributing to the distinguished properties, thus a detailed study of the structure-property relationship is especially significant. Herein, pH-sensitive optical properties of Nile Blue (1a), N-monoalkyl-Nile Blue (1b) and Azure A (1c) have been carried out in extreme acid and base conditions. Dyes 1a and 1c showed colorimetric changes by the protonation of nitrogen atom in strong acidic condition (pH  7.6). Besides, their fluorescent properties were closed to ON - OFF and OFF - ON emissions at 640-820 nm under strong acidic and basic conditions. Moreover, the absorption and emission properties were reversible, and there were no remarkable optical intensity changes of dyes 1a - c under subacidic and neutral solutions (pH = 3.0-7.0). The (TD) DFT calculations were used to optimize the most stable structures of their corresponding protonated and deprotonated forms, and their absorption and emission properties were also explained. Their fluorescent properties nearly ON-OFF and OFF - ON in strong acidic and basic conditions at near-infrared region will give the possible application in pH detection for extreme conditions.

    The redox active nanoparticles were developed by covalently attaching redox dye Azure C (AZU) to commercial silica nanoparticles (SN) via the silylated amine and glutaric dialdehyde links. The SN-AZU nanoparticles were studied as redox mediators for the oxidation of reduced β-nicotinamide adenine dinucleotide (NADH) in two polymeric films. The first film (F1) was composed of SN-AZU, carbon nanotubes, and cationic polyelectrolyte chitosan. The second film (F2) contained also added enzyme glucose dehydrogenase and its cofactor β-nicotinamide adenine dinucleotide (NAD(+)). The films F1 and F2 were cast on the glassy carbon electrodes, covered with an anionic polyelectrolyte Nafion, and their electrochemical properties were probed with NADH and glucose, respectively, using voltammetry, amperometry, and potentiometry. The Nafion overcoat reduced the sensitivity of F1/Nafion film electrodes to NADH by >98%. In contrast, depending on the concentration of Nafion, the sensitivity of the F2/Nafion film electrodes (reagentless biosensors) to glucose increased by up to 340%. The amplification of glucose signal was ascribed to the Donnan exclusion and ensuing Nafion-gated ionic fluxes, which enhanced enzyme activity in films F2. The proposed model predicts that such signal amplification should be also feasible in the case of other enzyme-based biosensors.

    The implementation of wireless sensor networks (WSNs) for monitoring the complex, dynamic, and harsh environment of underground coal mines (UCMs) is sought around the world to enhance safety. However, previously developed smart systems are limited to monitoring or, in a few cases, can report events. Therefore, this study introduces a reliable, efficient, and cost-effective internet of things (IoT) system for air quality monitoring with newly added features of assessment and pollutant prediction. This system is comprised of sensor modules, communication protocols, and a base station, running Azure Machine Learning (AML) Studio over it. Arduino-based sensor modules with eight different parameters were installed at separate locations of an operational UCM. Based on the sensed data, the proposed system assesses mine air quality in terms of the mine environment index (MEI). Principal component analysis (PCA) identified CH₄, CO, SO₂, and H₂S as the most influencing gases significantly affecting mine air quality. The results of PCA were fed into the ANN model in AML studio, which enabled the prediction of MEI. An optimum number of neurons were determined for both actual input and PCA-based input parameters. The results showed a better performance of the PCA-based ANN for MEI prediction, with R ² and RMSE values of 0.6654 and 0.2104, respectively. Therefore, the proposed Arduino and AML-based system enhances mine environmental safety by quickly assessing and predicting mine air quality.

    In this study we have investigated the molecular background of the previously reported dye decolourization potential of Bacillus sp. LD003. Strain LD003 was previously isolated on Kraft lignin and was able to decolourize various lignin model dyes. Specifically Azure B (AB) was decolourized efficiently. Proteins possibly involved in AB decolourization were partially purified, fractionated by gel electrophoresis and identified via mass spectrometry. Five candidate enzymes were selected and expressed in Escherichia coli. Of these, only a quinone dehydrogenase was shown to decolourize AB. Thus, this quinone dehydrogenase was identified as an AB decolourizing enzyme of Bacillus sp. LD003. Copyright © 2012 Elsevier B.V. All rights reserved.

    Full Text Available In this paper, multi-walled carbon nanotube/Azure A/gold nanoparticle composites (Nafion/AuNPs/AzA/MWCNTs were prepared by binding gold nanoparticles to the surfaces of Azure A-coated carbon nanotubes. Nafion/AuNPs/AzA/MWCNTs based electrochemical sensor was fabricated for the simultaneous determination of ascorbic acid, dopamine, uric acid, and tryptophan. Cyclic voltammetry and electrochemical impedance spectroscopy were used to characterize the electrochemical properties of the modified electrodes. The modified electrode showed excellent electrocatalytic activity toward ascorbic acid, dopamine, uric acid, and tryptophan (pH 7.0. The experiment results showed that the linear response range for simultaneous detection of AA, DA, UA and Trp were 300–10,000 μM, 0.5–50 μM, 0.5–50 μM and 1.0–100 μM, respectively, and the detection limits were 16 μM, 0.014 μM, 0.028 μM and 0.56 μM (S/N = 3. The proposed method offers promise for simple, rapid, selective and cost-effective analysis of small biomolecules. The procedure was also applied to the determination of tryptophan in spiked milk samples.

    A novel nonenzymatic hydrogen peroxide sensor was developed using graphene/Nafion/azure I/Au nanoparticles composites modified glass carbon electrode (graphene/Nafion/AzI/AuNPs/GCE). The method of preparation of graphene/Nafion/AzI/AuNPs composite was simple and it was characterized by SEM. Cyclic voltammetry demonstrated that the direct electron transfer of redox molecule, Azure I, was realized, and the sensor had an excellent performance in terms of electrocatalytic reduction toward hydrogen peroxide (H 2 O 2 ). The sensor showed high sensitivity and fast response upon the addition of H 2 O 2 , under the conditions of pH 4.0, potential −0.2 V. The time to reach the stable-state current was less than 3 s, and the linear range to H 2 O 2 was from 30 μM to 5 mM with a detection limit of 10 μM (S/N = 3). Moreover, the sensor exhibited good reproducibility and long-term stability

    In the present study, in depth characterization of binding aspects of Azure A (AZA) and Azure B (AZB) with transfer Ribonucleic acid (t-RNA) from Escherichia coli (E.coli) is investigated using spectroscopic techniques. The absorbance and fluorescence properties of these dyes have been remarkably changed upon binding with t-RNA. Significant changes in the absorption maxima of the dyes evidence the t-RNA induced metachromasy and the binding clearly revealed the high affinity of AZA and AZB to t-RNA. Strong emission polarization of the bound dyes and strong energy transfer from the guanine base pairs of t-RNA suggested intercalative binding interaction. The stoichiometry of AZA and AZB with t-RNA complexes are determined by the Benesi-Hildebrand plot from emission data. The negative values of free energy change indicated the involvement of hydrophobic forces and noncovalent interactions in the complexation of both the dyes with t-RNA. The 3-(4,5- dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) colorimetric assay in A-549 human lung cancer cell lines reveals that binding of t-RNA reduces the toxicity of AZA and AZB. The utility of the present work explores the potential binding applicability of these dyes to t-RNA for their development as effective therapeutic agents and its target at molecular level for the treatment of diseases like cancer.

    The aim of this work was to improve the ability of electro-Fenton technique for the remediation of wastewater contaminated with synthetic dyes using a model azo dye such as Azure B. Batch experiments were conducted to study the effects of main parameters, such as dye concentration, electrode surface area, treatment time, and voltage. In this study, central composite face-centered experimental design matrix and response surface methodology were applied to design the experiments and evaluate the interactive effects of the four studied parameters. A total of 30 experimental runs were set, and the kinetic data were analyzed using first- and second-order models. The experimental data fitted to the empirical second-order model of a suitable degree for the maximum decolorization of Azure B by electro-Fenton treatment. ANOVA analysis showed high coefficient of determination value (R(2) = 0.9835) and reasonable second-order regression prediction. Pareto analysis suggests that the variables, time, and voltage produce the largest effect on the decolorization rate. Optimum conditions suggested by the second-order polynomial regression model for attaining maximum decolorization were dye concentration 4.83 mg/L, electrode surface area 15 cm(2), voltage 14.19 V, and treatment time of 34.58 min.

    We describe the implementation of an automated infectious disease surveillance system that uses data collected from 210 microbiologic laboratories throughout the Provence-Alpes-Côte d'Azur region in France. Each week, these facilities report bacterial species that have been isolated from patients in their area. An alarm is triggered whenever the case count for a bacterial species infection exceeds 2 SDs of the historical mean for that species at the participating laboratory. At its inception in July 2013, the system monitored 611 bacterial species. During July 1, 2013-March 20, 2016, weekly analyses of incoming surveillance data generated 34 alarms signaling possible infectious disease outbreaks; after investigation, 14 (41%) of these alarms resulted in health alerts declared by the regional health authority. We are currently improving the system by developing an Internet-based surveillance platform and extending our surveillance to include more laboratories in the region.

    2012-07-01

    Full Text Available This article explores neo-impressionist representations of the Maures region (Hyères-St Raphaël of the Côte d'Azur as an ideal space of anarcho-communist liberty or, to borrow from Jean Grave's Terre Libre: Les Pionniers (1908, a "free land." In doing so it questions art-historical literature of such images as utopian, with its implication of geographic non-specificity, through analyses of anarcho-communist and geographical texts and images. Tropical markers, especially palm trees, feature in Grave's vision of a "free land," corresponding to perceptions by contemporaneous artists, tourists and geographers of the exotic, island-like geography of the Maures. The article argues that, for Henri-Edmond Cross, Paul Signac and Théo van Rysselberghe, the Maures landscape was imaged and imagined as a sunlit terre libreon home soil, naturally suited to these self-styled pioneers.

    Highlights: • The PAA-CS modified GCE was prepared using cyclic voltammetry. • Copper ions were strongly bound to the PAA-CS composites by complexation. • ·OH derived from the reaction between Cu 2+ and H 2 O 2 effectively oxidized PAA. • An electrochemical sensor of H 2 O 2 with good analytical performance was developed. - Abstract: In this work, a sensitive electrochemical method for the detection of H 2 O 2 was proposed based on Fenton-type reaction on the electrode surface. A glassy carbon electrode modified with poly(azure A) (PAA), chitosan (CS) and copper ions, displaying a good electrochemical activity, was fabricated by cyclic voltammetry and the adsorption of Cu 2+ . Scanning electron microscopy-Energy dispersive spectroscopy analysis, infrared and Raman spectral characterization and XPS measurement showed the stable complexation of Cu 2+ with the PAA-CS film. Hydroxyl radicals derived from the Fenton-type reaction between Cu 2+ and H 2 O 2 could effectively oxidize poly(azure A), leading to the great reduction-current change of the dye polymer in the electrode process. Under the optimized conditions, the fabricated electrode displayed a linear response in the H 2 O 2 concentration range from 0.002 to 0.5 mM and that from 2.56 to 25.0 mM with a detection limit of 0.7 μM estimated at a signal-to-noise ratio of 3. The good analytical performance including low detection limit, fast response time, low cost, good anti-interference performance, satisfying stability, acceptable repeatability and reliable reproducibility were found from the proposed amperometric sensor, suggesting that the current work could provide a feasible approach for the non-enzymatic H 2 O 2 detection.

    The heterogeneous photo-Fenton like process is a green chemical pathway.. It has an edge over conventional Fenton and photo-Fenton processes as it does not require the removal of ferrous/ferric ions in the form of sludge. We prepared copper pyrovanadate or Volborthite (Cu 3 V 2 (OH) 2 O 7 ·2H 2 O) composite photocatalyst by wet chemical method. The photocatalyst was characterized by SEM, XRD, IR, TGA/DSC, EDX and BET. Experiments demonstrated that catalyst could effectively catalyze degradation of neutral red and azure-B in presence of H 2 O 2 in visible light. Moreover, the photo-Fenton-like catalytic activity of Cu 3 V 2 (OH) 2 O 7 ·2H 2 O was much higher than CuO and V 2 O 5 , when used alone as photocatalyst. The effect of variation of different parameters, i.e., pH, amount of photocatalyst, concentration of dye, amount of H 2 O 2 and light intensity was also investigated. The degradation was well fitted under pseudo-first-order reaction with a rate constant of 2.081x10 −4 sec −1 and 3.876x10 −4 sec −1 for neutral red and azure-B, respectively. Quality parameters of dye solutions before and after photo-Fenton degradation were also determined. A tentative mechanism involving •OH radical as an oxidant has been proposed. The high catalytic activity may be due to the Cu 3 V 2 (OH) 2 O 7 ·2H 2 O shell, which not only increased the surface hydroxyl groups, but also enhanced the interfacial electron transfer.. The catalyst has been found to possess good recyclability

    We describe an electrochemical immunosensor for the simultaneous determination of alpha-fetoprotein (AFP) and prostate specific antigen (PSA) via a modified glassy carbon electrode. Silica nanoparticles (200–300 nm i.d.) with good monodispersity and uniform shape were synthesized, and the following species were then consecutively immobilized on their surface: gold nanoparticles (AuNPs; 5–15 nm i.d.), secondary antibody (Ab 2 ) and the redox-probes Azure A or ferrocenecarboxy acid (Fc). In parallel, two types of primary antibodies (Ab 1 ) were co-immobilized on the surface of the dissolved reduced graphene oxide sheets (rGO) that were also decorated with AuNPs. In the presence of antigens (AFP or PSA), the Ab 2 /Si-AuNPs carrying Azure A and Fc are attached to the AuNP/rGO conjugate via a sandwich type immunoreaction. Differential pulse voltammetry (DPV) was employed to measure the resulting changes in the signal of Fc or Azure A. Two well-resolved oxidation peaks, one at −0.48 V (corresponding to Azure A) and other at + 0.12 V (corresponding to Fc; both vs. SCE) can be observed in the DPV curves. Under optimal conditions, AFP and PSA can be simultaneously determined in the range from 0.01 to 25 ng mL -1 for AFP, and from 0.012 to 25 ng mL -1 for PSA. The detection limits are 3.3 pg mL -1 for AFP and 4.0 pg mL -1 for PSA (at a signal-to-noise ratio of 3). The method was applied to (spiked) real sample analysis, and the recoveries are within 96.0 and 107.2 % for PSA, and within 100.9 and 105.8 % for AFP, indicating that this dual immunosensor matches the requirements of clinical analysis.

    A simple and sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed for the quantification of methylene blue (MB) and its major metabolite, azure B (AZB), in rat plasma. A simple protein precipitation using acetonitrile was followed by injection of the supernatant on to a Zorbax HILIC Plus column (3.5 µm, 2.1 × 100 mm) with isocratic mobile phase consisting of 5 mM ammonium acetate in 10:90 (v/v) water:methanol at a flow rate of 0.3 mL/min and detection in positive ionization mode. The standard curve was linear over the concentration range from 1 to 1000 ng/mL for MB and AZB with coefficient of determination above 0.9930. The lower limit of quantification was 1 ng/mL using 20 μL of rat plasma sample. The intra- and inter-assay precision and accuracy were <12%.

    In the present study, the interaction of model transport proteins Human serum albumin (HSA) and Bovine serum albumin (BSA) with a photoactive dye, Azure B (AZB) were studied by spectroscopic and in silico methods. The absorption spectral behavior of AZB in the presence of varying concentrations of serum albumins (HSA and BSA) revealed the formation of dye aggregates within the protein cavity. The binding parameters computed from the emission quenching data showed that AZB bind to HSA and BSA with significant affinity and it was revealed that both the serum proteins (HSA and BSA) can bind AZB at more than one binding sites having at least one high-affinity binding site with different affinities (non-independent). The existence of static quenching mechanism was further evidenced from the time-resolved fluorescence spectroscopic analysis. Site-competitive replacement experiments with specific site markers showed that AZB binds to site I of HSA and BSA. AutoDock based blind docking approach and molecular dynamics simulation studies were used to analyze the most probable binding location of AZB in HSA and BSA. The AZB induced unfolding of HSA and BSA was established by using absorption, circular dichroism and FT-IR spectral studies. The influence of AZB complexation on the biological function of HSA and BSA was evaluated by probing the hydrolysis of p-nitrophenyl acetate. Copyright © 2016 Elsevier B.V. All rights reserved.

    Full Text Available In the present paper, poly(azure A (PAA films were electrosynthetized in the presence of different doping anions on disposable screen-printed carbon electrodes (SPCEs. The anions used included inorganic monoatomic (chloride and fluoride, inorganic polyatomic (nitrate and sulfate and organic polyatomic (dodecyl sulfate, DS species. The coated electrodes thus obtained were characterized by electrochemical techniques and SEM. They showed improved electrocatalytic activities towards hydrogen peroxide oxidation compared to that of a bare SPCE. In particular, the insertion of DS anions inside PAA films provided a special sensitivity to the electrocatalysis of H2O2, which endowed these electrodes with promising analytical features for H2O2 quantification. We obtained a wide linear response for H2O2 within a range of 5 µM to 3 mM and a limit of detection of 1.43 ± 0.10 µM (signal-to-noise ratio of 3. Furthermore, sensitivity was 72.4 ± 0.49 nA·µM−1∙cm−2 at a relatively low electrocatalytic oxidation overpotential of 0.5 V vs. Ag. The applicability of this boosted system was tested by the analysis of H2O2 in commercial samples of a hair lightener and an antiseptic and was corroborated by spectrophotometric methods.

    A novel amperometric enzyme immunosensor with amplified sensitivity for the determination of alpha-fetoprotein (AFP) was constructed with layer-by-layer assembly of ZnSe quantum dots (ZnSe QDs)/Azure I/gold nanoparticles (nanoAu)/poly (3,4-ethylenedioxythiophene) (PEDOT) on Pt electrode. Firstly, citrate coated nanoAu was immobilized on the PEDOT polymer film, which was electrochemically synthesized in ionic liquid electrolyte of 1-butyl-3-methylimidazolium tetrafluoroborate ([bmim][BF 4 ]). Then, Azure I was immobilized on nanoAu/PEDOT composite matrix as a redox probe and was used to immobilize ZnSe QDs. Subsequently, AFP antibody (anti-AFP) was adsorbed onto the surface of ZnSe layer. Finally, horseradish peroxidase (HRP) was employed to block sites against nonspecific binding and amplify the current signal of the antigen–antibody reaction. The modification processes were characterized by cyclic voltammetry, scanning electron microscopy. The factors influenced the performances of the proposed immunosensors were studied in detail. Because of the synergism between Azure I and nanoAu/PEDOT to facilitate electron-transfer process, and the small diameter of ZnSe QDs favorable for stabilization of biological activity to a large extent, the immunosensor displayed a high sensitivity, fast analytical time, a relatively low detection limit of 1.1 fg/mL at 3 times of signal-to-noise ratio (S/N = 3), and a especially broad linear response to AFP in a ranges from 5 × 10 −5 to 250 ng/mL. Moreover, the selectivity, repeatability, and stability of the proposed immunosensor were acceptable

    The main objective of this study is to give an insight on possible effects climate change may have on landscapes of the Provence-Alpes-Cote d'Azur region on the medium and long term according to current hypotheses regarding global warming for Mediterranean regions. A first phase aimed at identifying the main landscape settings of the region. This comprised a definition of the notion of landscape, a discussion of landscape definitions with respect to a regional scale, a framework for the definition of the main landscape settings, an identification of these landscape settings and their characterisation according to a set of criteria and parameters. The second phase aimed at giving an overview of hypotheses regarding climate change. The authors discuss various issues and knowledge about the world climate, available climate models and their uncertainties, and climatic predictions for the region. The third phase aimed at assessing predictable effects of climate change on emblematic landscapes and at defining actions plans. The different components of these action plans are then discussed for the identified landscapes for which the landscape context and challenges are described, and potential actors are indicated. These different phases are first presented, and more detailed reports are provided for each of them, notably with detailed reports and sheets for each landscape setting

    Adjuvant therapies can prevent/delay bone metastasis development in breast cancer. We investigated whether serum bone turnover markers in early disease have clinical utility in identifying patients with a high risk of developing bone metastasis. Markers of bone formation (N-terminal propeptide of type-1 collagen [P1NP]) and bone resorption (C-telopeptide of type-1 collagen [CTX], pyridinoline cross-linked carboxy-terminal telopeptide of type-1 collagen [1-CTP]) were measured in baseline (pretreatment blood samples from 872 patients from a large randomized trial of adjuvant zoledronic acid (AZURE-ISRCTN79831382) in early breast cancer. Cox proportional hazards regression and cumulative incidence functions (adjusted for factors having a statistically significant effect on outcome) were used to investigate prognostic and predictive associations between recurrence events, bone marker levels, and clinical variables. All statistical tests were two-sided. When considered as continuous variables (log transformed), P1NP, CTX, and 1-CTP were each prognostic for future bone recurrence at any time (P = .006, P = .009, P = .008, respectively). Harrell's c-indices were a P1NP of 0.57 (95% confidence interval [CI] = 0.51 to 0.63), CTX of 0.57 (95% CI = 0.51 to 0.62), and 1-CTP of 0.57 (95% CI = 0.52 to 0.63). In categorical analyses based on the normal range, high baseline P1NP (>70 ng/mL) and CTX (>0.299 ng/mL), but not 1-CTP (>4.2 ng/mL), were also prognostic for future bone recurrence (P = .03, P = .03, P = .10, respectively). None of the markers were prognostic for overall distant recurrence; that is, they were bone metastasis specific, and none of the markers were predictive of treatment benefit from zoledronic acid. Serum P1NP, CTX, and 1-CTP are clinically useful, easily measured markers that show good prognostic ability (though low-to-moderate discrimination) for bone-specific recurrence and are worthy of further study. © The Author(s) 2018.

    Full Text Available This work presents a catalogue of the tsunamis generated in the seas watering the Italian coasts, including the neighbouring area of Côte d'Azur (France. Events generated far from Italy and affecting the Italian coasts are not taken into account here. The catalogue, that we will also call the Quick-Look Catalog (QLC, is organised in three main sections that are named the Quick-Look Table, the Quick-Look Accounts File and the References File, having the respective abbreviations of QLT, QLAF and RF. The QLT is a synoptic table containing the relevant information available for each event, one table row corresponding to one event. More details are provided in the QLAF, where each event is dedicated a specific subsection: here the description of the tsunami includes all essential aspects that are suitably referenced and is preceded by a concise report concerning the tsunami cause. Lastly, the RF is the list of all the papers and publications quoted in the QLT and QLAF. Notice that efforts have been made to qualify each event by means of contemporaneous sources, although later sources and indirect sources, such as existing catalogues, have not been disregarded. Besides, specific recent studies on the events have been given special mention. In this work some general review of the past catalogues of tsunamis and of recent trends in the subject are expressed. Particularly, great attention is given to analysing the CFB of the Italian tsunamis due to Caputo and his collaborators (Caputo and Faita, 1984; Bedosti and Caputo, 1986, the acronym being formed by the ordered initials of the authors. Motivations clarifying the need for a new catalogue of the Italian tsunamis are illustrated circumstantially. The very different philosophies that are at the basis of the CFB and of the present QLC lead to quite diverse products and results, that are summarised by a table where the events included in the CFB and in the QLC are compared: the net effect of the rigorous

    The role of adjuvant bisphosphonates in early breast cancer is uncertain. We therefore did a large randomised trial to investigate the effect of the adjuvant use of zoledronic acid on disease-free survival (DFS) in high-risk patients with early breast cancer. In the AZURE trial, an open-label, international, multicentre, randomised, controlled, parallel-group phase 3 trial, women (age ≥18 years) with stage II or III breast cancer were randomly assigned (1:1) by a central automated 24-h computer-generated telephone minimisation system (balanced for number of involved axillary lymph nodes, tumour stage, oestrogen receptor status, type and timing of systemic therapy, menopausal status, statin use, and treatment centre) to receive standard adjuvant systemic treatment alone (control group) or with 4 mg intravenous zoledronic acid every 3-4 weeks for six doses, then every 3 months for eight doses, followed by every 6 months for five doses, for a total of 5 years of treatment. The primary endpoint was disease-free survival (DFS). Secondary endpoints were invasive DFS (IDFS), overall survival, time to bone metastases, time to distant recurrence, and subgroup analyses of variables included in the randomisation. All patients have completed study treatment. Results from the intention-to-treat final analysis of this fully recruited study are presented after a median follow-up of 84 months (IQR 66-93). This final efficacy analysis was planned to take place after 940 DFS events. This trial is registered with ClinicalTrials.gov, NCT00072020. 3360 women were recruited from 174 centres in seven countries between Sept 4, 2003, and Feb 16, 2006. The number of DFS events did not differ between groups: 493 in the control group and 473 in the zoledronic acid group (adjusted hazard ratio [HR] 0·94, 95% CI 0·82-1·06; p=0·30). IDFS (HR 0·93, 95% CI 0·82-1·05; p=0·22), overall survival (0·93, 0·81-1·08; p=0·37), and distant recurrences (0·93, 0·81-1·07; p=0·29) were much

    The AZURE trial is an ongoing phase III, academic, multi-centre, randomised trial designed to evaluate the role of zoledronic acid (ZOL) in the adjuvant therapy of women with stage II/III breast cancer. Here, we report the safety and tolerability profile of ZOL in this setting. Eligible patients received (neo)adjuvant chemotherapy and/or endocrine therapy and were randomised to receive neither additional treatment nor intravenous ZOL 4 mg. ZOL was administered after each chemotherapy cycle to exploit potential sequence-dependent synergy. ZOL was continued for 60 months post-randomisation (six doses in the first 6 months, eight doses in the following 24 months and five doses in the final 30 months). Serious (SAE) and non-serious adverse event (AE) data generated during the first 36 months on study were analysed for the safety population. 3,360 patients were recruited to the AZURE trial. The safety population comprised 3,340 patients (ZOL 1,665; control 1,675). The addition of ZOL to standard treatment did not significantly impact on chemotherapy delivery. SAE were similar in both treatment arms. No significant safety differences were seen apart from the occurrence of osteonecrosis of the jaw (ONJ) in the ZOL group (11 confirmed cases; 0.7%; 95% confidence interval 0.3-1.1%). ZOL in the adjuvant setting is well tolerated, and can be safely administered in addition to adjuvant therapy including chemotherapy. The adverse events were consistent with the known safety profile of ZOL, with a low incidence of ONJ.

    Adjuvant use of bisphosphonates can reduce the incidence of bone metastases in early breast cancer. Recurrence and survival seem to be improved only in postmenopausal patients, but the underlying mechanisms remain unclear. We investigated whether MAF amplification (a biomarker for bone metastasis) in primary tumours could predict the treatment outcomes of adjuvant zoledronic acid. The study population included patients enrolled in the international, open-label, randomised, controlled, phase 3 AZURE trial at eligible UK sites who had stage II or III breast cancer and who gave consent for use of their primary tumour samples. Patients were randomly assigned (1:1) to receive standard adjuvant systemic therapy alone (control group) or with zoledronic acid every 3-4 weeks for six doses, then every 3-6 months until the end of 5 years. Minimisation took into account the number of involved axillary lymph nodes, clinical tumour stage, oestrogen-receptor status, type and timing of systemic therapy, menopausal status, statin use, and treating centre. The primary endpoint was disease-free survival; the secondary endpoint, invasive-disease-free survival, was the primary disease endpoint for the analysis in this report. MAF amplification was assessed by fluorescence in-situ hybridisation of two cores of breast tumour tissue in a microarray, done in a central laboratory by technicians unaware of treatment assignment. We used multivariate analyses to assess disease outcomes by intention to treat. We also assessed interactions between MAF-positive status and menopausal status on efficacy of zoledronic acid. The AZURE trial is registered with the International Standard Randomised Controlled Trial Registry, number ISRCTN79831382. 1739 AZURE patients contributed primary tumour samples, of whom 865 (50%) had two assessable cores (445 in the control groups and 420 in the zoledronic acid group). 184 (21%) tumours were MAF positive (85 in the control groups and 99 in the zoledronic acid

    A continuous adsorption was used for removal of azure II (AZ II) and auramine O (AO) from aqueous solutions using Pinus eldarica stalks activated carbon (PES-AC) from aqueous solutions. The effects of initial dye concentration, flow rate, bed height and contact time on removal percentage of AO and AZ II were evaluated and optimized by central composite design (CCD) at optimum pH = 7.0. ZnO nanoparticles loaded on activated carbon were also used to remove AO and AZ II at pH = 7.0 and other optimum conditions. The breakthrough curves were obtained at different flow rates, initial dye concentrations and bed heights and the experimental data were fitted by Thomas, Adams-Bohart and Yoon-Nelson models. The main parameters of fixed-bed column including its adsorption capacity at breakthrough point (q b ), adsorption capacity at saturation point (q s ), mass transfer zone (MTZ), total removal percentage (R%), and empty bed contact time (EBCT) were calculated. The removal percentages calculated for AZ II and AO II were in the range of 51.6-61.1% and 40.6-61.6%, respectively. Bed adsorption capacity (N 0 ) and critical bed depth (Z 0 ) were obtained by BDST model. Copyright © 2017 Elsevier Inc. All rights reserved.

    The first part of this document aims at presenting perspectives of emergence of new energy production, consumption and storage sources, and their impacts on energy (electricity, gas, heat) distribution and transport networks. It is based on two scenarios: the regional climate-air-energy scheme, and the regional Negawatt scenario. The objective was to select a limited number of aspects: solutions enabling an optimal injection of biogas produced in the concerned region, development of photovoltaic energy and electric vehicles and their impact on the balance of medium-voltage and low-voltage networks, and smart grid technologies and their possible impact on the optimisation of electric network management. The second part reports the detailed study of these issues. It more particularly addresses technical impacts of different sectors on electric and gas networks in Provence-Alpes-Cote d'Azur, technical, economic and organisational assets of smart grid technologies, investments policies and implementation planning, and resulting evolutions for energy markets.

    At the request of the Hospitalization Regional Agency (ARH)--in the context of the 2007-2011 plan aimed at improving the quality of life for patients affected by chronic diseases--the purpose of this work was to draw up a clear assessment of the 2008 Therapeutic Education programmes in the Provence-Alpes-Côte d'Azur (PACA) region. The study was carried out before the publication of the therapeutic education statutory orders and ARS (regional health agency) authorizations. Cross-sectional study, carried out in the three sectors of medical management in the region--namely health-care institutions, ambulatory structures and health networks--made it possible to identify, first, which structures had actually launched therapeutic education programmes and then, how the procedures had been designed and set up. Among all the medical structures investigated, the study has listed 491 programmes, heterogeneously located throughout the PACA region. These programmes primarily target diabetes, respiratory and cardiovascular diseases. Their main objectives are the patients' quality of life, adherence to treatment and protective health behaviour (health improvement). The hospitalization sector programmes preferentially target the 30 to 60 years old, whereas the ambulatory and health networks programmes are more inclined to target the over 60 years old part of the population. More than 50% of the professionals involved in the programmes have never benefited from a specific training concerning the patients' therapeutic education. This study has pointed out a great number of important aspects which need drastic improvement in terms of therapeutic education organization - the involvement and training of health professionals, for instance.

    Full Text Available The identification of predators of birds' nests, crucial to a better understanding of predator-prey interactions, remains poorly known. Here we provide evidence that birds, and especially passerines, may depredate birds' nests in the Cerrado (Neotropical Savannah of Central Brazil. Data was collected primarily in a Conservation Unit (Estação Ecológica de Águas Emendadas during the breeding season, between 2003 and 2007. We report and discuss details on 14 events of nest predation, 12 of which by passerines, mostly by curl-crested jays - Cyanocorax cristatellus (Temminck, 1823. The results of our study suggest that the role of birds as nest predators in the Cerrado has been underestimated and needs to be further investigated.

La maîtrise des consommations énergétiques, en particulier des consommations d'électricité, est l'un des piliers évoqués par les pouvoirs publics pour une mise en œuvre de la transition énergétique. Une approche infrarégionale permet de caractériser les comportements des territoires face à cette consommation, d'en rechercher les déterminants et de s'interroger sur les types d'actions à mettre en œuvre. Il est possible de mettre en évidence les contingences locales qui confèrent aux espaces de la région Paca un caractère énergivore du point de vue des consommations d'électricité du secteur résidentiel. La méthodologie développée repose sur une analyse en composantes principales et une classification ascendante hiérarchique pour l'élaboration d'une typologie d'espaces énergivores qualifiés autant par leurs fonctions (résidentielle, activités économiques, tourisme…, que par le type d'habitat qui les caractérise (maisons individuelles, appartements. La cartographie des résultats obtenus permet de territorialiser les types et d'engager une réflexion sur la dimension territoriale de la mise en œuvre de la transition énergétique.

  13. What is Radical Behaviorism? A Review of Jay Moore's Conceptual Foundations of Radical Behaviorism

    Science.gov (United States)

    Baum, William M

    2011-01-01

    B. F. Skinner founded both radical behaviorism and behavior analysis. His founding innovations included: a versatile preparation for studying behavior; explicating the generic nature of stimulus and response; a pragmatic criterion for defining behavioral units; response rate as a datum; the concept of stimulus control; the concept of verbal behavior; and explicating the explanatory power of contingencies. Besides these achievements, however, Skinner also made some mistakes. Subsequent developments in radical behaviorist thought have attempted to remedy these mistakes. Moore's book presents a “party line” version of radical behaviorism. It focuses narrowly on a few of Skinner's concepts (mostly mentalism and verbal behavior) and contains no criticism of his mistakes. In fact, Moore adds a few mistakes of his own manufacture; for example, he insists that the mental realm does not exist—an unprovable and distracting assertion. The book's portrayal of behavior analysis would have been current around 1960; it mentions almost none of the developments since then. It also includes almost no developments in radical behaviorism since Skinner. Moore's book would give an unwary reader a highly distorted picture of contemporary behavior analysis and radical behaviorism.

    2012-05-07

    Human activity and interaction data is beginning to be collected at population scales through the pervasiveness of social media and willingness of people to volunteer information. This can allow social science researchers to understand and model human behavior with better accuracy and prediction power. Political and social scientists are starting to correlate such large scale social media datasets with events that impact society as evidence abound of the virtual and physical public spaces intersecting and influencing each other [1,2]. Managers of Cyber Physical Systems such as Smart Power Grid utilities are investigating the impact of consumer behavior on power consumption, and the possibility of influencing the usage profile [3]. Data collection is also made easier through technology such as mobile apps, social media sites and search engines that directly collect data, and sensors such smart meters and room occupancy sensors that indirectly measure human activity. These technology platforms also provide a convenient framework for “human sensors” to record and broadcast data for behavioral studies, as a form of crowd sourced citizen science. This has the added advantage of engaging the broader public in STEM activities and help influence public policy.

    2004-01-01

    Researchers, hindered by a lack of standard gene and protein-naming conventions, endure long, sometimes fruitless, literature searches. A system is described which is able to automatically assign gene names to their LocusLink ID (LLID) in previously unseen MEDLINE abstracts. The system is based on supervised learning and builds a model for each LLID. The training sets for all LLIDs are extracted automatically from MEDLINE references in the LocusLink and SwissProt databases. A validation was done of the performance for all 20,546 human genes with LLIDs. Of these, 7,344 produced good quality models (F-measure > 0.7, nearly 60% of which were > 0.9) and 13,202 did not, mainly due to insufficient numbers of known document references. A hand validation of MEDLINE documents for a set of 66 genes agreed well with the system's internal accuracy assessment. It is concluded that it is possible to achieve high quality gene disambiguation using scaleable automated techniques.

    A simple, accurate and rapid spectrophotmeric method was proposed for the determination of chondroitin sulfate. The method was based on the absorbances of AA-CS complex at 625 nm being in proportion to the chondroitin sulfate concentrations. The linear range was 0-30 micrograms.mL-1 (R = 0.999), and the recovery range was 97.4%-103.8%. The quantities of chondroitin sulfate in different sample were determined in this way.

  3. Adjuvant bone-targeted therapy to prevent metastasis: lessons from the AZURE study.

    Science.gov (United States)

    Coleman, Robert E

    2012-09-01

    Bone-targeted treatments with bisphosphonates (e.g., zoledronic acid) and denosumab are known to reduce the risk of skeletal complications and prevent treatment-induced bone loss in patients with malignant bone disease. Additionally, these drugs may modify the course of bone destruction via inhibitory effects on the 'vicious cycle' of growth factor and cytokine signalling between tumour and bone cells within the bone marrow microenvironment. In early stage breast cancer, treatment with zoledronic acid has shown improvements in disease-free and overall survival, notably in women with established menopause at diagnosis and in premenopausal women with endocrine-responsive disease, treated with goserelin to suppress ovarian function. Other bisphosphonates such as clodronate may produce similar benefits. Additionally, in castrate-resistant prostate cancer, treatment with denosumab delays the development of bone metastases. These results strongly support the adjuvant use of bone-targeted treatments, but suggest that reproductive hormones are an important treatment modifier to take into account.

    Science.gov (United States)

    1966-01-01

    NASA research pilot Milt Thompson is helped into the cockpit of the M2-F2 lifting body research aircraft at NASA's Flight Research Center (now the Dryden Flight Research Center). The M2-F2 is attached to a wing pylon under the wing of NASA's B-52 mothership. The flight was a captive flight with the pilot on-board. Milt Thompson flew in the lifting body throughout the flight, but it was never dropped from the mothership. NASA B-52, Tail Number 008, is an air launch carrier aircraft, 'mothership,' as well as a research aircraft platform that has been used on a variety of research projects. The aircraft, a 'B' model built in 1952 and first flown on June 11, 1955, is the oldest B-52 in flying status and has been used on some of the most significant research projects in aerospace history. Some of the significant projects supported by B-52 008 include the X-15, the lifting bodies, HiMAT (highly maneuverable aircraft technology), Pegasus, validation of parachute systems developed for the space shuttle program (solid-rocket-booster recovery system and the orbiter drag chute system), and the X-38. The B-52 served as the launch vehicle on 106 X-15 flights and flew a total of 159 captive-carry and launch missions in support of that program from June 1959 to October 1968. Information gained from the highly successful X-15 program contributed to the Mercury, Gemini, and Apollo human spaceflight programs as well as space shuttle development. Between 1966 and 1975, the B-52 served as the launch aircraft for 127 of the 144 wingless lifting body flights. In the 1970s and 1980s, the B-52 was the launch aircraft for several aircraft at what is now the Dryden Flight Research Center, Edwards, California, to study spin-stall, high-angle-of attack, and maneuvering characteristics. These included the 3/8-scale F-15/spin research vehicle (SRV), the HiMAT (Highly Maneuverable Aircraft Technology) research vehicle, and the DAST (drones for aerodynamic and structural testing). The aircraft supported the development of parachute recovery systems used to recover the space shuttle solid rocket booster casings. It also supported eight orbiter (space shuttle) drag chute tests in 1990. In addition, the B-52 served as the air launch platform for the first six Pegasus space boosters. During its many years of service, the B-52 has undergone several modifications. The first major modification was made by North American Aviation (now part of Boeing) in support of the X-15 program. This involved creating a launch-panel-operator station for monitoring the status of the test vehicle being carried, cutting a large notch in the right inboard wing flap to accommodate the vertical tail of the X-15 aircraft, and installing a wing pylon that enables the B-52 to carry research vehicles and test articles to be air-launched/dropped. Located on the right wing, between the inboard engine pylon and the fuselage, this wing pylon was subjected to extensive testing prior to its use. For each test vehicle the B-52 carried, minor changes were made to the launch-panel operator's station. Built originally by the Boeing Company, the NASA B-52 is powered by eight Pratt & Whitney J57-19 turbojet engines, each of which produce 12,000 pounds of thrust. The aircraft's normal launch speed has been Mach 0.8 (about 530 miles per hour) and its normal drop altitude has been 40,000 to 45,000 feet.. It is 156 feet long and has a wing span of 185 feet. The heaviest load it has carried was the No. 2 X-15 aircraft at 53,100 pounds. Project manager for the aircraft is Roy Bryant.

    2010-12-01

    Whereas the wind sector displays a particularly strong growth, and the PACA region possesses a lot of natural resources and assets regarding wind energy, this study aims at providing information and other elements to be used for a better definition of future wind energy projects in this region. Based on a regional wind energy atlas, it aims at providing technical, environmental, and regulatory constraints, as well as landscape studies, and thus a relevant decision-making tool for the development of wind energy in PACA. It is based on an inventory, classification and cartography of environmental, technical and regulatory issues and servitudes, a map of identified landscape settings, a map of wind resources, and an assessment of exploitable areas and of potential production. The report proposes a detailed overview of various issues: in terms of environment, heritage (protected areas, regulations), landscape, and in terms of technical issues (civil, military and meteorological servitudes, housing, power grid, seismic and fire risks). Then, after a presentation of the assessment methodology, it indicates the determination of the exploitable area, of wind power per square kilometre, and of results in terms of potential power by 2020 and by 2030, and of avoided CO 2 emissions and jobs

    This article presents the results of a tentative application of Solid Phase Micro Extraction (SPME) to the analysis of BTEX (benzene, toluene, ethyl-benzene and xylenes) at the {mu}g/m{sup 3} level in indoor and outdoor air. The salient features of the method validation are reported. Sampling by QUALITAIR using Radiello passive samplers, was carried out from 2001 to 2004 in the city of Nice and its airport. Urban traffic impact was proved, but a link between BTX concentrations and the variations of airport activities was not clearly established. During the same period, several samplings were performed using SPME. Taking into account the short (30 minutes) sampling time, rapid changes of BTEX concentrations were evidenced, as for example the start of airplane engines. As field studies have shown, SPME technique appears as a method of choice for fast qualitative analysis and quantitative determination of Volatile Organic Compounds (VOC). The small dimensions of the SPME sampling system and the short sampling time let envisage its utilisation for the rapid diagnostic and the monitoring of indoor air quality. (author)

Issues addressed in these documents evolve in time as the concept of renewable energy emerged, as important consuming sector are identified (transports, buildings, for example), and also as the issue of energy saving is more precisely studied. Activities of the regional energy observatory are also mentioned. From 2013, issues related to climate and air quality are also addressed at the same level as power production, solar photovoltaic and thermal energy, wind energy, wood-energy, energy savings, energy prices, studies performed by the observatory, and issues related to transports

    A first part of this report proposes an analysis of the existing supply, demand and competition for the wood pellet production sector. More precisely, it proposes a brief analysis of the European pellet market and of its operation, a study of the individual PACA market (pellet market, actors, market price and evolutions in the region), and a competitive analysis. The second part reports the study of mobilisable resources. It proposes a resource analysis (potential resource identification, analysis of the regional wood sector production, other resource usages, mobilisable resources), a market and resource synthesis, an overview of possible processes (with or without drying), and a discussion of criteria to be taken into account. The third part reports a technical-economic study for the implementation of small wood pellet production units in the region. It addresses the different possible processes, compares them in terms of social and environmental assessments, and in terms of global feasibility. It also proposes a decision-making tool which comprises criteria to be taken into account and elements of thought related to regional policy

    Basic studies on coal desulphurization by pyrolysis have been carried out with a series of low rank coals with high total sulphur contents and differences in the distribution of sulphur forms. The evolved sulphur compounds were studied by sulphide selective electrode H{sub 2}S and Fourier transform infrared (FTIR) spectroscopy. The mechanisms affecting the sulphur removal during pyrolysis have been studied by scanning electron microscopy coupled with energy dispersive X-ray (SEM-EDX), X-ray diffraction (XRD) and photoelectronic spectroscopy (XPS). A sample coal of 11 Tm, representative of the Teruel basins was processed at pilot scale in a rotary kiln (coal HR). A series of pyrolysis runs simulating the experimental conditions of the rotary kiln were also carried out in laboratory scale. The magnetic behaviour of the chars from the rotary kiln and from the lab-scale pyrolysis was tested. The efficiency of the desulphurization, including pyrolysis and magnetic separation, was calculated. Chars from rotary kiln were tested by thermogravimetric analysis, air reactivity and carbon efficiency combustion in fluidized bed.

    A method for the determination of methylene blue (MB) and its metabolites (azure A, azure B and azure C) in rat blood by CE-electrospray ionization mass spectrometry (CE-ESI-MS) was developed in this paper. Different analytical parameters were investigated in detail such as pH and concentration of separation buffer, and ESI-MS instrumental parameters. Under the optimum conditions, MB and its metabolites were separated and detected in 27.3 min. LODs (defined as S/N=3) of this method were 0.22, 0.25, 0.10 and 0.30 μg/mL for MB, azure A, azure B and azure C, respectively. To get a satisfactory extraction efficiency of MB and its metabolites in rat blood, different extraction solutions were studied. By using this method, MB and its metabolites (azure A, azure B and azure C) were successfully analyzed in rat blood samples. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Schulte, E; Wittekind, D; Kretschmer, V

    1989-01-01

    In the present study we have investigated the uptake of cationic thiazine dyes and of the anionic Eosin Y by red blood cells (RBCs). Blood smears were stained with Azure B-Eosin Y, Methylene Blue-Eosin Y, Thionin-Eosin Y and with the cationic and anionic dyes alone at varying concentrations. Dye content of erythrocytes was measured with a Vickers M 85a microdensitometer. Nuclear chromatin features of white blood cells were investigated with the IBAS 2000 image analyser. Azure B favoured Eosin Y uptake of RBCs remarkably, and vice versa. There was no clear indication of that type of molecular interaction which characterizes the generation of the colour purple on polyanions. Methylene Blue and Thionin left Eosin Y uptake unaffected, but contamination of the standard Azure B-Eosin Y stain with Methylene Blue obviously affected Azure B-Eosin Y uptake, probably by competition of Methylene Blue and Azure B binding in RBCs. Furthermore, Methylene Blue contamination of the standard stain increased the rate of error in image analysis of white blood cell nuclei due to variations of staining intensity. For cytophotometry and image analysis of blood smears the standard Azure B-Eosin Y stain is by far superior to the commercial stain which normally is contaminated with Methylene Blue and some of the lower azures.

    With the industrial revolution and then the massive use of fossil fuels, the air quality has been considerably worsening. Air quality is a complex function of meteorological situations (wind, sun radiation) and pollutant emissions. All those parameters must be accounted for modelling the reactive transports of pollutants in the atmosphere but only the anthropogenic emissions can be managed on a short time frame, as well concerning the composition of the flux as the emitted quantities. This overall modelling problematic emphasize the crucial role of emission databases in the air quality modelling processes, as diagnostic or prognostic tool for air quality issues. To obtain a consistent and realistic modelling, not only the emissions and meteorological data have to be taken take into account, especially the emissions in the proper chemical reaction mechanisms but the quality of the emission data is crucial. The starting point of our study was that few or no inventories exist, and from the ones available, they are not adapted to be used efficiently in regional air quality modelling. The resolution, especially regarding spatial emission distribution of the national inventories can not lead to proper input data for this kind of studies. Our study include both the method aspects (theoretical studies) and the operational aspects (applied studies) regarding the generation of high resolution spatial emission data (based on national statistical data standards) that can be used as suitable input data for meso-scale photochemical models of the reactive transport of pollutants. This work was part of the ESCOMPTE program, an unparalleled scientific in the domain of air quality experiment in France. Our tasks in this program also included a methodological transfer (accompanied with the software tools related to the emission databases) of the study to the local air quality monitoring authority (AIRMARAIX for the city of Marseille). This overall application proved the feasibility of high resolution regional emission inventories at a sustainable operational cost. (author)

    The interaction of Azure B with sodium alginate and heparin in aqueous solution has been studied by spectrophotometric method. Absorbance of Azure B at 645 nm decreases and a new band appeared at 545 nm and at 556 nm respectively which indicated that a new metachromatic complex formed. A linear decrease in absorbance is noted. It was found that sodium alginate is more effective than heparin in decreasing the absorbance of Azure B at 645 nm. The stoichiometry of sodium alginate or heparin with Azure B was determined by spectrophotometry. The results suggested that the interaction between Azure B with sodium alginate or heparin was a result of electrostatic forces and the difference between heparin and sodium alginate were attributed to the different negative charge number on repetitive disaccharides unit. Studies on the effect of alcohol or urea indicated that sodium alginate and heparin interacted with the aggregates of Azure B. Thermodynamic parameters of interaction has been evaluated to determine the stability of the metachromatic complex. The effect of surfactants on reversal of metachromasy has also been studied.

From the total of recorded species, eight are confirmations (Anas platyrhynchos domesticus, Cairina moschata, Bubulcus ibis, Columba livia, Sturnus vulgaris, Turdus rufopalliatus, Quiscalus mexicanus and Passer domesticus and four are new records (Aratinga canicularis, Amazona oratrix, A. autumnalis and Cyanocorax yncas. Although not all exotic species represent a risk because of the lack of the necessary resources for the establishment of abundant viable populations, it is important to publicize their status in the region. Therefore, knowing the presence of exotic species in a new distribution area is important for monitoring its establishment and colonization, and defining management, control and eradication programs of these species, along with environmental education programs that would lead to a better understanding of impacts that these species can cause.

    Full Text Available Objective – To determine the use and construct validity of a method to assess the cognitive impact of information derived from daily e-mail evidence based summaries (InfoPOEMs, and to describe the self-reported impact of these InfoPOEMs.Design – Prospective, observational study over a period of 150 days employing a questionnaire and rating scale.Setting – This study was conducted via the Internet between September 8, 2006 and February 4, 2007.Subjects – Canadian Medical Association (CMA members who received InfoPOEMs via e-mail as of September 2006 were invited to participate. For inclusion in the analyses, a participant was defined as a practising family physician or general practitioner who submitted at least five ratings of InfoPOEMS during the study period (n=1,007.Methods – Volunteers completed a demographic questionnaire and provided informed consent online. Each subsequent InfoPOEM delivered included a link to a “ten-item impact assessment scale” (241. Participants checked “all that apply” of descriptive statements such as: My practice was (will be improved; I learned something new; I think this information is potentially harmful. Each combination of selections made was considered a pattern of cognitive impact. College of Family Physicians of Canada received continuing medical education (CME credit for each InfoPOEM rated. Data were collected by the CMA and forwarded weekly to the investigators who used descriptive statistics, principal component analysis, and multilevel factor analysis to analyze the data.Main Results – 1,007 participants rated an average of 61 InfoPOEMs (ranging from five to 111. A total of 61,493 patterns of cognitive impact were submitted. Eighty-five different patterns were observed, i.e., there were 85 different combinations of the scale’s statements used. Ten patterns accounted for 89.4% of the reports. The top five patterns were: I learned something new (35.2%; No impact (17.1%; This information confirmed I did (will do the right thing (9.6%; I learned something new AND My practice will be improved (9.4%; and, I was reassured (5.6%. I disagree with this information was checked at least once by 10.3% of the participants, and 8.0% checked I think this information is potentially harmful at least once.Conclusion – The authors applied a cognitive assessment instrument to determine the impact of InfoPOEMs e-mailed to primary care physicians in Canada and found that ten combinations of impact descriptors accounted for 89.4% of the total reports. Most suggested a positive impact on knowledge or practice. Of the total, 17.1% indicated No impact and 1.8% indicated the participant was frustrated as there was not enough information or nothing useful.

    2010-01-01

    Throughout my internship, I assisted with the long-term monitoring of the Florida Scrub- Jay (Aphelocoma coerulescens), a threatened species endemic to Florida. The Florida Scrub Jay diet consists of insects and small vertebrates throughout most of the year; however, during the winter their primary diet is acorns because the insect population is low. Furthermore, the Florida Scrub-Jay is a habitat specialist that lives in a disappearing plant community called the scrub, which consists of sand live oak, myrtle oak and chapman oak. The Florida Scrub-Jay is considered threatened because its numbers are decreasing primarily due to the loss of habitat that it needs to survive. Scrub habitat is highly desirable for human development because it is high, dry, and sandy. Periodic controlled burns maintain the scrub in a low, open condition favored by Scrub-Jays. Florida Scrub-Jays build their nests approximately 3-5 feet (approximately 1.5 m) above the ground in shrubby oaks (Breininger 153), mate for life and are cooperative breeders; which means that the young jays remain in their natal territory for at least a year to help their parents defend their territory, feed the young, and mob predators. (Breininger 152). I assisted in conducting monthly censuses at long-term monitoring sites and a juvenile in July survey to determine reproductive success for the year. In addition, to Scrub-Jay monitoring, I also had the opportunity to assist with some long term monitoring of ecosystem recovery. Scrub is a fire maintained system. Fire maintains the structure of scrub necessary for many of the threatened species that reside in the scrub habitat.

  14. Understanding Romanowsky staining. I: The Romanowsky-Giemsa effect in blood smears.

    Science.gov (United States)

    Horobin, R W; Walter, K J

    1987-01-01

    Normal blood smears were stained by the standardised azure B-eosin Y Romanowsky procedure recently introduced by the ICSH, and the classical picture resulted. The effects of varying the times and temperature of staining, the composition of the solvent (buffer concentration, methanol content, & pH), the concentration of the dyes, and the mode of fixation were studied. The results are best understood in terms of the following staining mechanism. Initial colouration involves simple acid and basic dyeing. Eosin yields red erythrocytes and eosinophil granules. Azure B very rapidly gives rise to blue stained chromatin, neutrophil specific granules, platelets and ribosome-rich cytoplasms; also to violet basophil granules. Subsequently the azure B in certain structures combines with eosin to give purple azure B-eosin complexes, leaving other structures with their initial colours. The selectivity of complex formation is controlled by rate of entry of eosin into azure B stained structures. Only faster staining structures (i.e. chromatin, neutrophil specific granules, and platelets) permit formation of the purple complex in the standard method. This staining mechanism illuminates scientific problems (e.g. the nature of 'toxic' granules) and assists technical trouble-shooting (e.g. why nuclei sometimes stain blue, not purple).

  16. Microspectrophotometric studies of Romanowsky stained blood cells. I. Subtraction analysis of a standardized procedure.

    Science.gov (United States)

    Galbraith, W; Marshall, P N; Bacus, J W

    1980-08-01

    This paper describes a microspectrophotometric study of blood smears stained by a simple, standardized Romanowsky technique, using only the dyes azure B and cosin. Absorbance spectra are presented for twenty-two classes of cellular object, and for the two dyes in solution, together with tabulations of spectral maxima, and suitable wavelengths for use in automated image processing. The colours of objects stained with azure B/eosin are discussed in terms of absorbance spectra. By a spectral subtraction technique, it is shown that the differential colouration of various cell structures may be explained satisfactorily in terms of the varying proportions of only four dye components. These are the monomers and dimers of azure B and eosin. Polymerization was found to occur both in solution and on binding to biopolymers. A similar analysis of a conventional Romanowsky stain would present much greater difficulties, due to the greater number of dye components, which, however, contribute little to the colours observed.

  17. The influence of Romanowsky-Giemsa type stains on nuclear and cytoplasmic features of cytological specimens.

    Science.gov (United States)

    Schulte, E; Wittekind, D

    1989-04-01

    The aim of the present study was to compare the staining pattern of the standard azure B-eosin Y stain with commercial May-Grünwald-Giemsa (MGG) stains on cytological specimens by means of high resolution image analysis. Several cytological specimens (blood smears, abdominal serous effusions, bronchial scrape material) were air dried, methanol fixed and stained with the standard azure B-eosin Y stain and with commercial May-Grünwald-Giemsa stains. Integrated optical density (IOD) and colour intensities of cell nuclei and cytoplasm were measured with the IBAS 2000 image analyser. Commercial MGG stains gave much higher coefficients of variation for all parameters than the standard stain. Reproducibility of cell nuclei segmentation versus cytoplasm was significantly better for the standard stain. Contamination of the standard stain with methylene blue partly copied the staining pattern of commercial stains. The standard azure B-eosin Y stain is recommended for high resolution image analysis (HRIA) of cytological samples.

  20. Mobbing calls signal predator category in a kin group-living bird species.

    Science.gov (United States)

    Griesser, Michael

    2009-08-22

    Many prey species gather together to approach and harass their predators despite the associated risks. While mobbing, prey usually utter calls and previous experiments have demonstrated that mobbing calls can convey information about risk to conspecifics. However, the risk posed by predators also differs between predator categories. The ability to communicate predator category would be adaptive because it would allow other mobbers to adjust their risk taking. I tested this idea in Siberian jays Perisoreus infaustus, a group-living bird species, by exposing jay groups to mounts of three hawk and three owl species of varying risks. Groups immediately approached to mob the mount and uttered up to 14 different call types. Jays gave more calls when mobbing a more dangerous predator and when in the presence of kin. Five call types were predator-category-specific and jays uttered two hawk-specific and three owl-specific call types. Thus, this is one of the first studies to demonstrate that mobbing calls can simultaneously encode information about both predator category and the risk posed by a predator. Since antipredator calls of Siberian jays are known to specifically aim at reducing the risk to relatives, kin-based sociality could be an important factor in facilitating the evolution of predator-category-specific mobbing calls.

  14. Mast Cell Density in Oral Lesions using Metachromatic Stains: A Comparative Study

    Directory of Open Access Journals (Sweden)

    Shilpa Chirappurath Natesan

    2017-10-01

    Full Text Available Introduction: Mast Cells (MCs are bone marrow derived granular cells, distributed throughout the body near blood vessels, nerves and subepithelial areas. MC granules stain by basic dyes but are most readily demonstrated by metachromatic dyes such as toluidine blue and azure A. Aim: This study focuses on evaluating and comparing the count of MCs by identification and staining of these cells by azure A with toluidine blue as a control, in normal oral mucosa and in various other oral pathologies. Materials and Methods: Five cases each of Normal Oral Mucosa (NOM, Inflammatory Fibrous Hyperplasia (IFH, Oral Pyogenic Granuloma (OPG, Oral Lichen Planus (OLP and Oral Squamous Cell Carcinoma (OSCC were stained with 1% toluidine blue and azure A. Results: Mean MC count was higher in all four lesions when compared to normal oral mucosa with both stains. OLP exhibited the maximum amount of mean MC count when compared to other pathologies under study. With all four lesions, toluidine blue exhibited higher number of MC density (count/high power field compared to azure A. Conclusion: Higher count of MCs was noticed in all four lesions indicating a possible role of MCs in their pathogenesis either directly or indirectly. Also, the number of degranulated MCs was more in OLP followed by OSCC, IFH and OPG.

    Full Text Available This work aimed to determine the richness of the avifauna of the Municipal Park of Sabiá, urban perimeter of the municipality of Uberlândia (Brazil, and also to evaluate possible differences in composition among the several landscapes in the study area. The work was accomplished from July 2000 to November 2002, including at least one month of observation in the period of the morning (7:00-11:00 and totalling 33 visits (334 hours. The registrations were made along a transect that crossed different landscapes. A total of 149 species distributed in 16 orders, 38 families and 131 genders were recorded. Five species of endemic birds of the Cerrado were present in the survey: Herpsilochmus longirostris, Hylocryptus rectirostris, Antilophia galeata, Cyanocorax cristatellus and Basileuterus leucophrys. Most of the birds (80% were classified as residents or probable residents in the Park. The main alimentary guilds were insectivorous (n = 52; 35%, omnivorous (n = 46; 31% and frugivorous (n = 13; 9%. All areas were considered similar and had a Sorensen index above 0.80, probably associated with the proximity and connectivity of the investigated areas. The results indicate that the Park of Sabiá can be considered an important location for the maintenance of the regional avifauna.

  16. Steller sex: infidelity and sexual selection in a social Corvid (Cyanocitta stelleri.

    Directory of Open Access Journals (Sweden)

    Katlin R Overeem

    Full Text Available Genetic analysis of avian mating systems has revealed that more than 70% of monogamous species show incidence of offspring parentage that does not match the social partner. Extra-pair parentage (EPP has been linked to a variety of factors, including size and symmetry of ornamental traits, coloration, resource availability, and local conspecific density. We examined how ornamental plumage traits of individual Steller's jays (Cyanocitta stelleri and territory characteristics influence genetic fidelity of socially monogamous pairs. We used seven highly polymorphic microsatellite markers to assign paternity to 79 offspring, and identified 12 (15.2% as extra-pair young (EPY. Steller's jays with extra-pair young had significantly lower values of feather brightness and hue, indicating more ultraviolet-blue shifted coloration, and nested in closer proximity to the forest edge than Steller's jays with no detected EPY. Body size, crest height, asymmetry of ornamental crest stripes, as well as vegetative composition of territories and their proximity to supplemental feeders appeared to have little relationship to EPP. These results indicate that extra-pair parentage plays a role in the evolution of secondary sexual characteristics in both sexes, and suggest local density and availability of resources may influence Steller's jay mating dynamics.

  5. Standardization of the Romanowsky staining procedure: an overview.

    Science.gov (United States)

    Bentley, S A; Marshall, P N; Trobaugh, F E

    1980-01-01

    Commerically available Romanowsky blood stains are variable mixtures of thiazein dyes and brominated fluorescein derivatives with varying degrees of metallic salt contamination in a number of different solvent systems. There is a need for standardized Romanowsky stains of constant composition, which, when used in conjunction with a carefully controlled specimen preparation technique, should give consistent performance. Such a preparation system would be of great value to hematologists in general and would be essential to the validity of data obtained by the digital processing of blood cell images. It is possible to prepare standardized Romanowsky stains as mixtures of two or three dye components, namely, eosin Y, azure B and methylene blue, although azure B has only recently become commercially available at an acceptable degree of purity. The logistic problems of stain standardization are discussed.

    Full Text Available A total of 245 yeast isolates from Gunung Halimun National Park (GHNP were screened for cellulolytic activity using 0.2% cellulose-azure. The results showed that 16 isolates have cellulolytic activity using cellulose-azure assay. These isolates were further screened for carboxymethyl cellulase (CMCase, avicelase and cellobiase using specific substrates (carboxymethyl cellulosa, avicel and cellobiose with Teather and Wood method. The results showed that 7 isolates have CMCase; 6 isolates have cellobiase; 2 isolates have CMCase and cellobiase; and 1 isolate has CMCase and avicelase and cellobiase activities. Isolate S 4121 has the highest CMCase activity and identified as Trichosporon sporotrichoides (van Oorschot van Oorschot and de Hoog UICC Y-286.

  7. A comparative spectroscopic study of thiourea effect on the photophysical and molecular association behavior of various phenothiazine dyes

    Science.gov (United States)

    Ghanadzadeh Gilani, A.; Dezhampanah, H.; Poormohammadi-Ahandani, Z.

    2017-05-01

    This paper describes the role of a structure breaking additive (thiourea) on the photophysical and molecular association of a series of phenothiazine dyes in aqueous media using the absorption and fluorescence spectroscopic methods for the first time. The studied dyes were thionine, azure A, azure B, toluidine blue, and methylene blue. The spectral data were analyzed using DECOM program. Relevant spectral parameters in the dye solutions were estimated and discussed based on the chemical structure of the additive and excitonic treatment. The observation of spectral changes in the spectral data of the (water-additive-dye) system indicates the possible structure formation between the dye and additive molecules. However, it is found that in the high concentrations of thiourea the dimer geometries (H- and J-type dimers) are influenced by the dye-additive interactions. As a result, a competition between the dye-additive and dye-dye interactions was also observed.

  8. Encapsulation of titanium (IV) silsesquioxane into the NH4USY zeolite: Preparation, characterization and application

    International Nuclear Information System (INIS)

    Ribeiro do Carmo, Devaney; Dias Filho, Newton Luiz; Ramos Stradiotto, Nelson

    2007-01-01

    This work describes the encapsulation of titanium (IV) silsesquioxane into the supercavities of NH 4 USY ultra stabilized zeolite, after chemical treatment. The modified zeolite was characterized by Fourier transform infrared spectra, Nuclear magnetic resonance, scanning electronic microscopy, X-ray diffraction and thermogravity. This encapsulated titanium (IV) silsesquioxane can adsorb Azure A chloride after treatment with H 3 PO 4 , without modifier leaching problems. In an electrochemical study, the cyclic voltammograms of the graphite paste modified electrode, shows two redox couples with formal potential (E 0 ') -0.1 V and 0.21 V to I and II redox couples respectively (v=700mVs -1 ; Britton Robinson buffer (B-R) solution, pH 3) versus SCE ascribed to a monomer and dimmer of azure.

    AZUR SPACE Solar Power GmbH has developed a novel type of dense array module for use in parabolic dishes. Such dishes never produce a perfectly homogeneous, rectangular light spot but an inhomogeneous light distribution. A regular module would use this light distribution very inefficiently. Therefore AZUR SPACE developed a dense array module concept which can be adapted to inhomogeneous light spots. It is populated with state of the art triple junction solar cells.The modules are designed for light intensities in the range of 50-100 W/cm 2 and are actively water cooled. Prototypes are installed in 11 m 2 parabolic dishes produced by Zenith Solar. A peak output of 2.3 kW electrical and 5.5 kW thermal power could be demonstrated. The thermal power may be used for solar heating, solar cooling or warm water.

    It had been observed that cell films where DNA had been partially digested by DNase stained differentially by the standard RG stain and a representative commercial Giemsa mixture. The reasons for this divergence were experimentally investigated. The lower concentration of Azure B in the commercial Giemsa mixture as compared with the standard RG stain emerged as the most likely factor causing the divergence of staining behaviour. A correlation of this assumption to the theory of the RG stain is tentatively suggested.

    Methylene blue, currently in phase 3 clinical trials against Alzheimer Disease, disaggregates the Tau protein of neurofibrillary tangles by oxidizing specific cysteine residues. Here, we investigated if methylene blue can inhibit caspases via the oxidation of their active site cysteine. Methylene blue, and derivatives, azure A and azure B competitively inhibited recombinant Caspase-6 (Casp6), and inhibited Casp6 activity in transfected human colon carcinoma cells and in serum-deprived primary human neuron cultures. Methylene blue also inhibited recombinant Casp1 and Casp3. Furthermore, methylene blue inhibited Casp3 activity in an acute mouse model of liver toxicity. Mass spectrometry confirmed methylene blue and azure B oxidation of the catalytic Cys163 cysteine of Casp6. Together, these results show a novel inhibitory mechanism of caspases via sulfenation of the active site cysteine. These results indicate that methylene blue or its derivatives could (1) have an additional effect against Alzheimer Disease by inhibiting brain caspase activity, (2) be used as a drug to prevent caspase activation in other conditions, and (3) predispose chronically treated individuals to cancer via the inhibition of caspases.

    It can be natural to believe that many of the traditional issues of scale have been eliminated or at least greatly reduced via cloud computing. That is, if one can create a seemingly wellfunctioning cloud application that operates correctly on small or moderate-sized problems, then the very nature of cloud programming abstractions means that the same application will run as well on potentially significantly larger problems. In this paper, we present our experiences taking MODISAzure, our satellite data processing system built on the Windows Azure cloud computing platform, from the proof-of-concept stage to a point of being able to run on significantly larger problem sizes (e.g., from national-scale data sizes to global-scale data sizes). To our knowledge, this is the longest-running eScience application on the nascent Windows Azure platform. We found that while many infrastructure-level issues were thankfully masked from us by the cloud infrastructure, it was valuable to design additional redundancy and fault-tolerance capabilities such as transparent idempotent task retry and logging to support debugging of user code encountering unanticipated data issues. Further, we found that using a commercial cloud means anticipating inconsistent performance and black-box behavior of virtualized compute instances, as well as leveraging changing platform capabilities over time. We believe that the experiences presented in this paper can help future eScience cloud application developers on Windows Azure and other commercial cloud providers.

  3. Spectrophotometric determination of microamounts of boron in water

    1980-01-01

    A fast method of boron in water determination has been studied for the 0.5 .- 2 μg ml -1 concentration range. The procedure is based on the formation of a coloured complex of the tetrafluoroborate of a thionine derivate cation, its extraction by an organic solvent and the further absorptiometric measurement in such media. Methylene blue and azur C were comparatively tested as organic reagents, with 1.2-dichloroethane as the extractant. The absorbance was measured at the maximum (658 nm). The tetrafluoroboric acid formation was reached in 20 min on a water-bath kept at 60 deg C. The sensitivity with methylene blue was higher than with azur C. The molar absorptivities were 65,000 and 38,000 (l mol -1 cm -1 ) respectively. For a boron concentration of 0.1 μg ml -1 the relative standard deviation was 9% for methylene blue and 7% for azur C. The procedure is applicable to the control of boron traces in heavy water of nuclear reactors refrigerating loops. (author) [es

    Schulte, E

    1987-01-01

    In this paper the influence of staining time on the staining pattern of Romanowsky-Giemsa (RG) type stains is investigated. Smears of rabbit bone marrow and of human venous blood were stained with azure B-eosin Y, azure A-eosin Y and with the cationic dyes alone under varying conditions of staining time and dye concentration. The stained smears were investigated by integrating microdensitometry. DNA-polyacrylamide (PAA) model films were stained with azure A-eosin Y, the extinction of the stained model films was determined by spectrophotometry. With increasing staining time the color of the cell nuclei changed from blue to an intense purple, the texture of the nuclear chromatin became more prominent. Prolonged staining resulted in over-staining of the cell nuclei with loss of a distinct chromatin texture. Besides such factors as dye concentration and pH of the staining solution standardization of staining time may be considered necessary for the reproducibility of the RG staining pattern.

    Background. The R-Matrix formalism is a crucial tool in the study of nuclear astrophysics reactions, and many codes have been written to implement the relevant mathematics. One such code makes use of Visual Basic macros. A further open-source code, AZURE, written in the FORTRAN programming language is available from the JINA collaboration and a C++ version, AZURE2, has recently become available. Purpose The detailed mathematics and extensive programming required to implement broadly applicable R-Matrix codes make comparisons between different codes highly desirable in order to check for errors. This paper presents a comparison of the three codes based around data and recent results of the astrophysically important {sup 18}F(p,α){sup 15}O reaction. Methods Using the same analysis techniques as in the work of Mountford et al. parameters are extracted from the two JINA codes, and the resulting cross-sections are compared. This includes both refitting data with each code and making low-energy extrapolations. Results All extracted parameters are shown to be broadly consistent between the three codes and the resulting calculations are in good agreement barring a known low-energy problem in the original AZURE code. Conclusion The three codes are shown to be broadly consistent with each other and equally valid in the study of astrophysical reactions, although one must be careful when considering low lying, narrow resonances which can be problematic when integrating.

    Removal of cationic dye, Azur II, and anionic dye, Reactive Red 2 (RR-2) from aqueous solutions, has been successfully achieved by using a modified agricultural biomaterial waste: cocoa shell husk (Theobroma cacao) treated by gliding arc plasma (CPHP). The biomass in its natural form CPHN and modified form CPHP was characterized by infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), and point of zero charge (pH pzc ). Experimental variables such as initial pH, contact time, and temperature were optimized for adsorptive characteristics of CPHN and CPHP. The results show that the removal of the Azur II dye was favorable in the basic pH region (pH 10) while the Reactive Red 2 dye was favorable in the acidic pH region (pH 2). The minimum equilibrium time for Azur II and RR-2 dye was obtained after 40 and 240 min, respectively. The adsorption kinetics and isotherm data obtained were best described by a pseudo-second-order kinetic rate model and a combination of Langmuir-Freundlich isotherm models. This work indicates that the plasma-treated raw materials are good alternative multi-purpose sorbents for the removal of many coexisting pollutants from aqueous solutions.

    Seed dispersal by birds is central to the passive restoration of many tree communities. Reintroduction of extinct seed dispersers can therefore restore degraded forests and woodlands. To test this, we constructed a spatially explicit simulation model, parameterized with field data, to consider the effect of different seed dispersal scenarios on the extent of oak populations. We applied the model to two islands in California's Channel Islands National Park (USA), one of which has lost a key seed disperser.We used an ensemble modelling approach to simulate island scrub oak (Quercus pacifica) demography. The model was developed and trained to recreate known population changes over a 20-year period on 250-km2 Santa Cruz Island, and incorporated acorn dispersal by island scrub-jays (Aphelocoma insularis), deer mice (Peromyscus maniculatus) and gravity, as well as seed predation. We applied the trained model to 215-km2 Santa Rosa Island to examine how reintroducing island scrub-jays would affect the rate and pattern of oak population expansion. Oak habitat on Santa Rosa Island has been greatly reduced from its historical extent due to past grazing by introduced ungulates, the last of which were removed by 2011.Our simulation model predicts that a seed dispersal scenario including island scrub-jays would increase the extent of the island scrub oak population on Santa Rosa Island by 281% over 100 years, and by 544% over 200 years. Scenarios without jays would result in little expansion. Simulated long-distance seed dispersal by jays also facilitates establishment of discontinuous patches of oaks, and increases their elevational distribution.Synthesis and applications. Scenario planning provides powerful decision support for conservation managers. We used ensemble modelling of plant demographic and seed dispersal processes to investigate whether the reintroduction of seed dispersers could provide cost-effective means of achieving broader ecosystem restoration goals on

    Full Text Available The Cerrado is still one of the most important ecosystems in Brazil, even though more than 50% of its area has been altered or converted to pastureland and plantations. Despite its intense degradation, few ecological processes that might affect its biodiversity have been evaluated. The goal of this study was to test the edge effect on the predation rates at natural and artificial nests, at the Ecological Station of Águas Emendadas, Federal District, Brazil. Natural nests were found and monitored every three to four days from September to December of 2004 in the interior and at the edge of the reserve. Artificial nests were placed at four distances from the edge (0, 500, 1000 and 2000 m in three spatial replicates in September and again in December of 2004. Each nest received one Japanese Quail and one plasticine egg and was monitored every five days, for 15 days. There was no difference between the rates of predation either in the natural nests or in the artificial nests between treatments. For one bird species, Elaenia chiriquensis (Lawrence, 1865, Tyrannidae, daily survival rates in the incubation and in the hatchling period had opposite values between the edge and the interior. Marks on plasticine eggs suggest that birds are the main predators. Estimates of the abundance of two potential nest predators, Cyanocorax cristatellus (Temminck, 1823, Corvidae and Canis familiaris (Linnaeus, 1758, Canidae, revealed no relationship with distance to the edge, nor with predation rates. Brood parasitism of natural nests was similar between the interior (0% and the edge (3.8% of the nests. The results described here do not support the edge effect hypothesis for nest predation rates on either natural or artificial nests, nor for brood parasitism rates.

    Inspired by Steller's jay, which displays angle-independent structural colors, angle-independent structurally colored materials are created, which are composed of amorphous arrays of submicrometer-sized fine spherical silica colloidal particles. When the colloidal amorphous arrays are thick, they do not appear colorful but almost white. However, the saturation of the structural color can be increased by (i) appropriately controlling the thickness of the array and (ii) placing the black background substrate. This is similar in the case of the blue feather of Steller's jay. Based on the knowledge gained through the biomimicry of structural colored materials, colloidal amorphous arrays on the surface of a black particle as the core particle are also prepared as colorful photonic pigments. Moreover, a structural color on-off system is successfully built by controlling the background brightness of the colloidal amorphous arrays. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    A classic paper in intellect and argument, this article contains a transcript of a conversation between Jay Haley, John Weakland, and Milton Erickson as they discuss the role of communication in hypnosis and schizophrenia. In 1955, schizophrenia was considered primarily a psychological disorder. Whereas today schizophrenia is mostly considered a biological disorder, this very early, unpublished paper still gives much food for thought and a further glimpse into Haley and Erickson's thinking and intellect at a fervent time in schizophrenia research.

    Stephen Jay Gould's views on the ontology of species were an important plank of his revisionist program in evolutionary theory. In this paper I cast a critical eye over those views. I focus on three central aspects of Gould's views on species: the relation between the Darwinian and the metaphysical notions of individuality, the relation between the ontology of species and macroevolution, and the issue of contextualism and conventionalism about the metaphysics of species.

In recent years, many companies looking for ways of getting out of clutter of traditional marketing implementations tend to apply guerrilla marketing which is a different way of marketing communication. Companies try to reach private worlds of consumers and give them memorable experience with their brands by guerrilla marketing strategies.
