Chemical composition and cytotoxicity activity of the essential oil of Pterodon emarginatus

Pterodon emarginatus Vogel, Fabaceae, is a native aromatic tree distributed by central region of Brazil. Hydroalcoholic infusions of the seeds are used in folk medicine for their anti-rheumatic and anti-inflammatory properties. The objective of this work was identified the chemical components and verify the cytotoxic effect of the essential oil (EO) from P. emarginatus seeds. Thus, the EO of P. emarginatus seeds was analyzed by GC/MS analysis followed by brine shrimp lethality test and cytotoxic activity against tumor cell lines and human peripheral mononuclear blood cells (PBMC). The cancer cell lines tested were C6 (rat glioma), MeWo (human melanoma), CT26.WT (mouse colon carcinoma), MDA (human breast cancer), A549 (human lung carcinoma), B16-F1 (mouse melanoma), CHO-K1 (hamster ovary cell) and BHK-21 (hamster kidney fibroblast). Eleven compounds were identified by GC and CG/MS analyses. The main compounds with concentrations higher than 5% were β-elemene (15.3%), trans-caryophyllene (35.9%), α-humulene (6.8%), germacrene-D (9.8%), bicyclo germacrene (5.5%) and spathulenol (5.9%). The EO of P. emarginatus seeds showed toxicity to Artemia salina (LC50 1.63 µg/mL) and was active against all the cell lines tested. The potent cytotoxic activity had IC50 values ranging from 24.9 to 47 µg/mL. However, EO (1-100 µg/mL) had less cytotoxicity in PBMCs isolated from a healthy subject. In summary, the present study showed the potential antiproliferative of the EO of P. emarginatus seeds.
Socially Beneficial Mergers: A New Class of Concentration Indices

The most prominent industry concentration index, the HerfindahlHirschman index (HHI), yields a higher concentration level in response to any merger between firms, thus implying that any merger will decrease the social welfare. Although HHI is the index used by the Anti-trust Division of the U.S. Department of Justice, its merger implications are not fully embraced by the anti-trust authorities; in practice, the Anti-trust Division allows many mergers especially among ∗We would like to thank John Boyd III, Jesse Bull, Andy Daughety, Michael Gort, Cem Karayalcin, Charles Register and Peter Thompson for their thoughtful insights and comments.

Facebook Effect on Academic Performance and Social Life for Undergraduate Students of University of Human Developments

The point of this paper is to look at the of Facebook use among college understudies and take some example in college of Human Development, and its effect on their scholastic execution and social life. Likewise, this paper delineates climate Facebook utilization have a positive or negative impact on their scholarly execution and social life. A study was intended for gathering information from few sample 110 college understudies in college on Human Development as straightforward dataset however we concentrate on a few social network report software for our outcomes. The aftereffect of overview demonstrates that the understudies that have less time spending on Facebook will lead expanded their evaluations. One of the fundamental discoveries is that there was a huge relationship between social life issues and Facebook utilization. Additionally, the review uncovered how long the understudy will spend on Facebook every day and tries to support the negative relationship between time spent on Facebook and the execution of college understudies. At last, this paper tries to give some recommendation to these understudies for tackling the scholastic execution and social life issues. According to our outcomes, Social Influence is the most essential component in foreseeing the selection of Facebook; understudies are affected to embrace it to set up or keep up contact with other individuals with whom they share intrigues. With respect to purposes of Facebook utilization, Social Relations is seen as the most imperative element among the greater part of the reasons gathered. Our discoveries likewise uncovered that the instructive utilization of Facebook is clarified straightforwardly by its reasons of use and by implication by its reception.
Engaging digital artworks through emotion: interface design case study

Artworks are often created to solicit emotional responses, yet the emotional elements are largely missing from artworks’ description and access options. In an effort to advance the design of emotion-based image retrieval systems, our study developed several research proposals for incorporating emotion into the description and access features of a digital artwork collection. Most of the proposed solutions for developing emotion metadata for artworks were informed by the current practices in information organization, including crowdsourcing and expert classifications. Being grounded in various emotion theories, the proposals offer a variety of ways to integrate emotion descriptors and navigation features into the interface design of a museum website. While the proposed solutions for integrating emotion features into online collections are not exhaustive, they highlight some of the design choices for developing emotion metadata, coding schemas and navigation features, and offer innovative ways to engage virtual visitors with museum digital collection.

Smoking, genetic polymorphisms of glutathione S-transferases and biological indices of inflammation and cellular adhesion in the STANISLAS study

A recent clinical study has focused on: 1- the interaction between genetic variants of glutathione S-transferases M1 and T1 (GSTM1 and GSTT1) and smoking on the risk of cardiovascular diseases, 2- the potential capacity of GSTM1 and T1 genotypes in modifying the effect of smoking on inflammation and endothelial function. In this study, we investigated whether carriage of these 2 polymorphisms altered the smoking impact on biological indices of inflammation and cellular adhesion. White blood cell count (WBC), albumin, C-reactive protein (CRP), interleukine-6 (IL-6), tumor necrosis factor-alpha (TNF-α), L-selectin, E-selectin, P-selectin and intracellular adhesion molecule-1 (ICAM-1) were measured in 189 non-smokers and 76 smokers (aged 20-55 years) genotyped for the GSTM1 and T1 polymorphisms. Accounting for age and sex, smokers lacking GSTM1 had a higher WBC count, CRP and ICAM-1 levels as compared to the other groups; interaction term between smoking and genotype being significant (p≤0.05). Conversely, non-smokers lacking GSTM1 had a higher levels of TNF-α; the test for interaction being significant (p≤0.05). No significant interaction was found between smoking and GSTT1 genotypes, considering the 9 biological indices. However, significantly lower levels of IL-6 were noticed for non-smokers with GSTT10 null allele (p≤0.05). Our study confirms previous results showing that GSTM1 polymorphism could modulate the interrelationships between smoking and biological markers of inflammation and endothelial function.
How to quantify competitive ability

Understanding the role of competition in structuring communities requires that we quantify competitive ability in a way that permits us to predict the outcome of competition over the long term. Given such a clear goal for a process that has been the focus of ecological research for decades, there is surprisingly little consensus on how to measure competitive ability, with up to 50 different metrics currently proposed. Using competitive population dynamics as a foundation, we define competitive ability—the ability of one species to exclude another—using quantitative theoretical models of population dynamics to isolate the key parameters that are known to predict competitive outcomes. Based on the definition of competitive ability we identify the empirical requirements and describe straightforward methods for quantifying competitive ability in future empirical studies. In doing so, our analysis also allows us to identify why many existing approaches to studying competition are unsuitable for quantifying competitive ability. Synthesis. Competitive ability is precisely defined starting from models of competitive population dynamics. Quantifying competitive ability in a theoretically justified manner is straightforward using experimental designs readily applied to studies of competition in the laboratory and field.
Mining and Predicting Smart Device User Behavior

Three types of user behavior are mined in this paper: application usage, smart device usage and periodicity of user behavior. When mining application usage, the application installation, most frequently used applications and application correlation are analyzed. The application usage is long-tailed. When mining the device usage, the mean, variance and autocorrelation are calculated both for duration and interval. Both the duration and interval are long-tailed but only duration satisfies power-law distribution. Meanwhile, the autocorrelation of both duration and interval is weak, which makes predicting user behavior based on adjacent behavior not so reasonable in related works. Then DFT (Discrete Fourier Transform) is utilized to analyze the periodicity of user behavior and results show that the most obvious periodicity is 24 hours, which is in agreement with related works. Based on the results above, an improved user behavior predicting model is proposed based on Chebyshev inequality. Experiment results show that the performance is good in accurate rate and recall rate.
SYNTHESIS OF GOLD NANOELECTRODE ENSEMBLES FOR BIOSENSING APPLICATIONS

Metal nanowires were synthesized according to an electroless deposition method in polycarbonate template, obtaining nano electrodes ensembles with specific features and well defined diameter size. Nano electrode ensembles were coupled with disposable screen printed substrate in order to increase the sensitivity of the commonly used carbon graphite working electrode for electrochemical sensing. Furthermore, working surface modification provided the basis for original protein immobilization procedures that otherwise would not be allowed.
Second‐order error propagation in the Mueller matrix of a spectropolarimeter

Accurate measurements of Stokes IQUV in spectral lines is required for precise reconstruction of stellar magnetic field geometries with Zeeman-Dopper imaging. Spectral Zeeman features are intrinsically weak and subjected to a number of instrumental uncertainties. The aim of this work is to study the details of the instrumental uncertainties in the Stokes IQUV measurements in spectral lines and ways of their reduction. We make a practical comparison of the polarimetric performances of two high-resolution echelle spectropolarimeters, namely SOFIN at the NOT, and HARPS at ESO. We show the residual spectra for both instruments to characterize the cross-talk between the observed Stokes parameters. We employ a self-calibrating least-squares fit to eliminate some of the polarization uncertainties to derive the full Stokes vector from stellar spectra (© 2011 WILEY-VCH Verlag GmbH & Co.

Characterization and Production of Extracellular polymeric substances ( EPS ) by Bacillus pseudomycoides U 10

Extracellular polymeric substances (EPSs) are important for industrial and medical relevance with significant commercial value. Different strategies are applied to reduce cost of production such as using cheaper substrates, improving product yield by optimizing fermentation conditions, or developing higher yielding strains via mutagenesis, and/or genetic and metabolic manipulations, and optimizing downstream processing. We aimed to determine the effect of whey, different pH values, temperature and incubation time on bacterial EPS production by Bacillus pseudomycoides U10. Maximum EPS production was obtained when 1 g/L whey was added to the growth medium. The optimum pH level was 7.0 and the highest EPS production was observed at 37 oC. According to X-ray diffraction, thermogravimetric EPSs have poorly crystalline nature and exhibit two step degradations, corresponding to weight loss of moisture and/or carboxyl group and pyrolysis of EPS, without distinctive changes in different media conditions. SAXS data indicate the layer thickness of the bacterial EPS is from 12.04 to 14.07 Å for whey and dissolved LB conditions, respectively. It was found that EPS structures changed with whey addition, such as, higher d-values, lower weight losses which seemed to be related to increasing durability and/or stability.

Elevated haemocyte number is associated with infection and low fitness potential in wild Daphnia magna

Summary 1. Immune activity may be a cause of resistance to parasites, but it can also be a consequence of infection. Thus, the adaptive significance of an immune response is more accurately assessed when it is measured alongside both host fitness and infection status. 2. We sought to determine the significance of immune responses in a naturally coevolving host–parasite system in the wild, with support from laboratory experiments. We measured haemocyte numbers in Daphnia magna in relation to an infection that has a clear fitness consequence: infection with the bacterium Pasteuria ramosa causes sterilization. 3. Haemocyte number was consistently elevated in infected Daphnia in the field and in parasite exposed or infected hosts in the laboratory. Thus, elevated haemocyte numbers were essentially a symptom of infection, and we found no evidence that haemocytes help hosts exclude the parasite. 4. Consequently, these results provide an especially clear example where increased immune activity does not mean increased immunity or fitness: hosts with the highest haemocyte counts have extremely low health and low fitness potential.
TLC Screening and Evaluation of Antioxidant, Antibacterial Activity of Onopordon Macrocephalum by Bioautography Method

TLC screening and Evaluation of antioxidant, antibacterial activity of Onopordon macrocephalum by bioautography methodOnopordon known as scotch thistle is a medicinal plant of the Asteraceae family that is widely distributed in Europe and Asia, also it has many valuable medicinal properties as hypotensive and antitumor. Thin layer chromatography (TLC) is wildly used in natural product extract analysis as a finger print which can be used for identification and quality control of medicinal preparations. Performing Thin-layer chromatography TLC tests on the plant show the presence of flavonoids, coumarins and bitter principles. Planar chromatographic analysis hyphenated with the biological detection method is known as bioautography which is an effective and inexpensive technique for the phytochemical analysis of plant extracts. Thin-layer chromatography-direct bioautography links separation on the adsorbent layer with biological tests performed directly on it in order to identify antimicrobial and antioxidant activities. Bioautography revealed that Staphylococcus aureus was inhibited by most of the flavonoids separated on the TLC plates. Similarly, growth of the Bacillus cereus was also inhibited by one flavonoid band on TLC. Antioxidant bioautography shows the strong antioxidant activity of one flavonoid band, whereas no activity detected of bitter principles. Bioautography showed that the antimicrobial and antioxidant activity was probably due to flavonoids.

A Review of the Concept of School-Based Leadership and Underlying Theories of Organizational Management

: This paper reviewed conceptions of school-based leadership and the theories of organizational management that underpin the various conceptions, and came out with an operational definition to enhance more understanding of the concept. From the review, it was emerged that there are two main schools of thought of the conception of school-based leadership. These conceptions are; the traditional concept and modern concept. The traditional conception is underpinned by the classical theory of organizational management, while the modern conception is underpinned by the human relation theory of organizational management. This paper recommends heads of schools to seek a broader understanding of the concept school-based leadership that reflects both the traditional and modern conceptions to enable them to have effective leadership for the various schools.
Taggle : Scaling Table Visualization through Aggregation

Tabular data visualizations are easy to understand and powerful at communicating patterns in datasets, especially when paired with interaction techniques such as sorting. In this work we present Taggle, a novel visualization technique for large and complex tables. We consider datasets that are composed of columns of categorical or numerical data, in addition to homogeneous matrices. The key contribution of Taggle is its ability to aggregate data subsets (rows and columns) on demand based on user-defined grouping rules. *e-mail: furmanova@mail.muni. cz †e-mail: jaresova@mail.muni. cz ‡e-mail: bikram.kawan@jku.at §e-mail: holger.stitz@jku.at ¶e-mail: martin.ennemoser@jku.at ||e-mail: samuel.gratzl@jku.at **e-mail: alex@sci.utah. edu ††e-mail: marc.streit@jku.at Different visual representations for individual cells and aggregated subsets are available.

Role of fibre in rabbit diets. A review

Role des fibres dans l'alimentation du lapin: revue. Cette revue concerne les effets des constituants parietaux sur le transit digestif, le controle de la flore intestinale, la fermentation caecale et les performances des lapins. Les caracteristiques, tant physiques que chimiques, des constituants parietaux interviennent sur ces variables. Un accroissement de la proportion des particules de petite taille ( 1,25 mm) est necessaire pour obtenir un taux de renouvellement du contenu caecal convenable et augmenter, ainsi, l'efficacite de la synthese microbienne. La digestibilite totale des parois cellulaires resulte en grande partie de celle des substances pectiques (arabinose, galactose et acides uroniques). Un accroissement de la teneur de ces constituants dans l'alimentation augmente l'acidite du contenu caecal et le recyclage des proteines microbiennes via la caecotrophie. La teneur en lignine du regime est negativement liee a l'energie digestible et a la repletion du caecum. Les niveaux tant excedentaires que deficitaires de constituants parietaux dans le regime donnent lieu a une diminution des performances des lapins. Des recommandations pratiques pour les teneurs optimales en constituants parietaux et la proportion minimale de particules de grande taille sont donnes pour les lapines allaitantes, les jeunes en croissance et les rations mixtes.
Measuring ecological niche overlap from occurrence and spatial environmental data

Aim Concerns over how global change will influence species distributions, in conjunction with increased emphasis on understanding niche dynamics in evolutionary and community contexts, highlight the growing need for robust methods to quantify niche differences between or within taxa. We propose a statistical framework to describe and compare environmental niches from occurrence and spatial environmental data. Location Europe, North America and South America. Methods The framework applies kernel smoothers to densities of species occurrence in gridded environmental space to calculate metrics of niche overlap and test hypotheses regarding niche conservatism. We use this framework and simulated species with pre-defined distributions and amounts of niche overlap to evaluate several ordination and species distribution modelling techniques for quantifying niche overlap. We illustrate the approach with data on two well-studied invasive species. Results We show that niche overlap can be accurately detected with the framework when variables driving the distributions are known. The method is robust to known and previously undocumented biases related to the dependence of species occurrences on the frequency of environmental conditions that occur across geographical space. The use of a kernel smoother makes the process of moving from geographical space to multivariate environmental space independent of both sampling effort and arbitrary choice of resolution in environmental space. However, the use of ordination and species distribution model techniques for selecting, combining and weighting variables on which niche overlap is calculated provide contrasting results. Main conclusions The framework meets the increasing need for robust methods to quantify niche differences. It is appropriate for studying niche differences between species, subspecies or intra-specific lineages that differ in their geographical distributions. Alternatively, it can be used to measure the degree to which the environmental niche of a species or intra-specific lineage has changed over time.
