Anti-apoptotic effects of phyllanthin against alcoholinduced liver cell death

Purpose : To evaluate the anti-apoptotic effect of phyllanthin on alcohol-induced liver cell death in HepG2 cells alone and in co-culture with human monocytic (THP-1) differentiated macrophage cells. Methods : Cell viability was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The cells were pretreated with 1, 5 and 10 μM phyllanthin for 24 h followed by 1300 mM alcohol for HepG2 cells and 2000 mM alcohol for the co-cultured cells. Thereafter, intracellular reactive oxygen species (ROS), mitochondrial membrane potential (MMP) changes, apoptotic cell death and caspase-3/7 activities were assessed. Results : Alcohol exposure significantly increased intracellular ROS generation (p < 0.001), decreased MMP changes (p < 0.001), increased the number of apoptotic and necrotic cells (p < 0.001) and also induced higher caspase-3/7 activity (p < 0.001) in the co-culture with THP-1 differentiated macrophage cells than in HepG2 cells alone. Pretreatment of HepG2 cells and co-cultured cells with phyllanthin for 24 h prior to alcohol exposure significantly decreased intracellular production of ROS (p < 0.001) and also increased the change in MMP (p < 0.001) as well as caused a decrease in the number of apoptotic and necrotic cells (p < 0.001), but inhibited caspase-3/7 activity (p < 0.001). Conclusion : The results indicate that phyllanthin treatment may have a significant therapeutic effect on alcohol-related liver diseases.

The role of colored accessory bracts in the reproductive biology of Lavandula stoechas

This study investigates the role played by showy structures in the repro- duction of Lavandula stoechas L. (Lamiaceae), a self-compatible Mediterranean shrub with compact, head-like inflorescences that are terminated by a tuft of conspicuous pink bracts. Pollinator visitation rates to plants with bracts correlated positively with that of paired, treated shrubs with all their bracts removed and, overall, bractless and control plants had equivalent visitation rates. In experimentally split shrubs, however, a strong effect on pollinator choice was evident, and distant visitor approaches were most often to that side keeping the attractive organs. Fecundity was not depressed in plants with reduced visual displays, and neither was the amount of pollen dispersed per flower or the size of stigmatic loads. There were, however, more pollen tubes, on average, at the lowermost part of the style in controls (10.8 tubes/style) than in bractless shrubs (8.3 tubes/style). Small, non- significant declines in average seed size, germinability, and seedling mass were detected following bract removal. Data support the notion that bracts are not essential to seed production in mature, relatively dense Lavandula populations where bee pollinators are often in good supply, but may be all-important if plant density is extremely low, or during population establishment. The role of an amplified display in increasing average pollination distance and progeny quality in this species is discussed.
Domain-Oriented Subject Aware Model for Multimedia Data Retrieval

With the increment of the scale of internet information as well as the cross-correlation interaction, how to achieve accurate retrieval of multimedia data is an urgent question in terms of efficiently utilizing information resources. However, existing information retrieval approaches provide only limited capabilities to search multimedia data. In order to improve the ability of information retrieval, we propose a domain-oriented subject aware model by introducing three innovative improvements. Firstly, we propose the text-image feature mapping method based on the transfer learning to extract image semantics. Then we put forward the annotation document method to accomplish simultaneous retrieval of multimedia data. Lastly, we present subject aware graph to quantify the semantics of query requirements, which can customize query threshold to retrieve multimedia data. Conducted experiments show that our model obtained encouraging performance results.
Relationship between Stock Prices and Exchange Rate: A Bivariate and Multivariate Analysis from Pakistan’s Economy

This research aims to find the relationship between stock prices and macroeconomic variables i.e. exchange rate, money supply, reserves, interest rate and inflation using data set of KSE100 from June, 1996 to December, 2010. Two measures of exchange rate are being used i.e. real effective exchange rate and nominal effective exchange rate. With Johansen co-integration test, FMOLS and Granger Causality tests as econometric techniques. No evidence of long-run relationship between stock price and exchange rate in bivariate models have been observed but in case of multivariate structure of model, stable long-run co-integration is being observed between stock prices and macroeconomic variables. Results indicate that exchange rate, money supply and interest rate are positive determinants of stock prices in Pakistan whereas negative impact of reserves and inflation is being found for stock price. In both cases bivariate and multivariate models, evidence of unidirectional causality from exchange rate to stock price has been observed. But the direction of macroeconomic variables gets differ in like unidirectional causal relationship is found between stock prices and inflation that runs from inflation to stock prices, from money supply to real effective exchange rate, consumer price index to real effective exchange rate, real effective exchange rate to Total reserve, Consumer price index to Total reserve, and Total reserves to Bank rate. However interest rate and reserves fails to establish any causal linkage with stock prices. Furthermore, unidirectional causality found that is running Keywords: Inflation, Money Supply, Asset Pricing, Portfolio Choice, Financial Markets JEL Classification: E31, E51, G12, G11, G15
Dynamic soaring mechanisms in the ocean boundary layer

Dynamic soaring is a flying technique which extracts energy from an environment where wind gradients form, such as the air-sea interface above oceans that sees such gradients developing through multiple and combined phenomena. Models of wind-wave interactions are analysed in terms of their influence on the induced wind field, before selecting a purely sinusoidal peak wave from the wave spectrum and developing the related wind field using stable laminar theory. Dynamic soaring trajectories are then derived by optimising a nonlinear constrained problem that models the evolution of a point mass vehicle. Characteristic phases of dynamic soaring flight are evidenced out of the overall trajectories and compared to the flat-ocean case in order to conclude on the influence of waves regarding dynamic soaring performances.
The ATLAS 5.5 GHz survey of the extended Chandra Deep Field South: the second data release

We present a new image of the 5.5 GHz radio emission from the extended Chandra Deep Field South. Deep radio observations at 5.5 GHz were obtained in 2010 and presented in the first data release. A further 76 hours of integration has since been obtained, nearly doubling the integration time. This paper presents a new analysis of all the data. The new image reaches 8.6 microJy rms, an improvement of about 40% in sensitivity. We present a new catalogue of 5.5 GHz sources, identifying 212 source components, roughly 50% more than were detected in the first data release. Source counts derived from this sample are consistent with those reported in the literature for S_{5.5GHz} > 0.1 mJy but significantly lower than published values in the lowest flux density bins (S_{5.5GHz} 0.5 mJy, consistent with the flattening of the spectral index observed in 5 GHz sub-mJy samples. The median spectral index of the whole sample is \alpha_{med} = -0.58, indicating that these observations may be starting to probe the star forming population. However, even at the faintest levels (0.05 ~ 0.1 mJy) show significant curvature in their radio spectral energy distribution spanning 1.4 to 9 GHz.
Hypsometric approaches to Eucalyptus experiments in Brazil

The objective of this study was to determine the best method to estimate tree height by different hypsometric approaches. This study is a provenance trial with Eucalyptus spp. in a 35-year-old pioneering plantation in the municipality of Lavras, Brazil. The census was taken by measuring the diameter at 1.30 m above ground and total height. All x and y coordinates of the individual trees were obtained and these trees were classified according to their stem quality. The ordinary kriging, cokriging and ordinary kriging of the residuals generated from the regression models were fitted by an exponential model. The Curtis model was selected for calculating the regression. The best method to estimate the height-diameter relationship was based on the statistical and graphical criteria. The spatial prediction model did not adequately represent the height–diameter relationship. The regression technique was more precise and accurate by inserting variables that helped capture different development standards of the trees. The regression-kriging produced more accurate total height estimates. Inclusion of the stochastic effect in the general spatial behavior of the total height variable helped to capture specific details about the stand. Therefore, this method is recommended for experimental areas.
Agricultural Teacher Perceptions of School Components as Motivational Factors to Continue Teaching and Demotivational Factors to Discontinue Teaching

It is widely recognized that the education profession has experienced an increased demand in the rapid push to prepare students for the 21stcentury. Although every child has the right to a high quality education, it is not certain that every student will be taught by a teacher that possesses the ambition, goals, and accountability to be an effective educator. Even more of a concern is the growing body of evidence that, given a variety of factors such as an aging teacher workforce and the increase in student enrollment numbers, it is projected that the number of public school teachers will increase to an average of over 300K per year (National Center for Education Statistics, 2011). In the field of agricultural education alone, there has been over a 20% decline in the number of newly qualified agricultural educators produced in addition to numerous agricultural teaching positions nationwide that will not operate due to the lack of a qualified teacher (Kantorvich, 2010). For these and other reasons, teacher retention has become an important agenda item for many school leaders.
Characteristics of recombinant maltogenic amylase from Geobacillus sp. SK70

A thermostable maltogenic amylase producing-bacterium was isolated from a 70°C hot spring at Sungai Klah, Perak, Malaysia and was designated as Geobacillus sp. SK70 based on the 16S rRNA gene analysis. The gene encoding a thermostable maltogenic amylase was expressed in Escherichia coli using pET102 Directional TOPO expression vector, and it is the first ever report on using such expression vector. The highest enzyme activity was obtained after 12 h of post-induction time using 0.02 mM isopropyl β-D-thiogalactopyranoside (IPTG). The enzyme was purified to homogeneity with 8.2-fold and 41% recovery through a single-step using His-Trap HP affinity column chromatography. The optimum temperature and pH of the purified enzyme was at 55°C and pH 7.0, respectively, and showed broad pH stability ranging from pH 5.0 to 10.0. The activity of the purified enzyme was stable in the presence of 1 mM Ca2+;stimulated by 1 mM Mn2+and Zn2+, and 0.1 % (v/v) Tween-20; and inhibited by 1% (v/v) of 2-mercaptolethanol, EDTA and SDS. Thus the enzyme could be considered Ca2+-independent, which demonstrated characteristic unlike other reported maltogenic amylases, and offered good characteristics for industrial applications.

Analyzing Clique Overlap

There are a large number of techniques that try and determine areas within a network in which individuals are more closely linked to each other than outsiders. However, once these cohesive subgraphs have been identified researchers are often left with a long list of overlapping subgroups and have no means of assessing the structure or importance of these groups. In this paper we examine techniques for describing and reducing the amount of overlap so that the analyst can better understand the complex underlying clique structure.
A survey of activity-based costing in hotel industry

Article history: Received March 25, 2015 Received in revised format June 1 2015 Accepted June 27 2015 Available online June 28 2015 This paper presents an empirical investigation on implementation of activity based cost (ABC) method in hotel industry. The study determines four possible factors of organizational, environmental, individual and technological, which could influence on ABC implementation. The study selects a sample of 205 employees who worked for Laleh International Hotel in Iran. Using one-way t-student test, the study has determined that all variables were effective on ABC implementation while individual factor was the most important one. In addition, correlation test has determined that all variables had meaningful correlations with each other. Further investigation indicates that gender did not play essential role for ABC implementation while experienced employee tended to be more effective for the success of ABC implementation.

DETECTION OF WINDOWS IN BUILDING TEXTURES FROM AIRBORNE AND TERRESTRIAL INFRARED IMAGE SEQUENCES

Infrared (IR) images depict thermal radiation of physical objects. Imaging the building facades and the roofs with an IR camera, thermal inspections of the buildings can be carried out. In such inspections a spatial correspondence between IR-images and the existing 3D building models can be helpful. Texturing 3D building models with IR images this spatial correspondence can be created. Furthermore in textures heat leakages can be detected and the heat bridges can be stored together with 3D building data. However, before extracting leakages, the windows should be located. In IR images glass reflects the surrounding and shows false results for the temperature measurements. Consequently, the windows should be detected in IR images and excluded for the inspection. The most common algorithms for window detection were developed for the images in the visual band. In this paper, an algorithm for window detection in textures extracted from terrestrial IR images is proposed. In the first step, small objects have to be removed by scaling down the image (texture). Then in the scaled image, regions are detected using a local dynamic threshold. Morphological operations are used to remove false detections and unify substructures of the windows. For every extracted region, which is a candidate for a window, the center of gravity is calculated. It is assumed that windows on facades are ordered in regular rows and columns. First the points are grouped into rows using histogram of height created from extracted gravity centers. Then masked correlation is used to detect the position and size of the windows. Finally, the gaps in the grid of windows are completed. For the first experiments we use a dataset from densely build urban area captured in Munich, Germany. The IR image sequences were taken from a vehicle driving on the street around the test area. Camera was directed to the building in oblique view. According to the acquisition geometry, no facade could be completely seen in one frame. Therefore, we combine the textures from many frames. To these textures we applied our algorithm for window detection. First results are promising. Applying the method for our test dataset, 79% completeness and 80% correctness could be achieved.
Students’ Lived Experience on The Toughest Place to be a Binman in Critical Listening and Speaking 1 Class

The use of authentic videos has been implemented in Critical Listening and Speaking 1 (CLS 1) class. For instance, the use of The Toughest Place to be a Binman video. This video gives the students meaningful experiences. The students do not only get the material but they can also get social and environment issues that appear in the video. After watching the video, the students are expected to have their own experience towards the use of The Toughest Place to be a Binman video in CLS 1. Therefore, the aim of this research was to have a better understanding on the students’ lived experience on The Toughest Place to be a Binman in CLS 1. This research employed phenomenology study because this research focused on the students’ lived experience. As a research result, the research showed the participants’ stories and the interpretation. There were four emerging themes that appeared from the data processed. Those were meaningfulness, compassion, motivation, and action. Those four themes connected between each other.

Blockwise and coordinatewise thresholding to combine tests of different natures in modern ANOVA

We derive new tests for fixed and random ANOVA based on a thresholded point estimate. The pivotal quantity is the threshold that sets all the coefficients of the null hypothesis to zero. Thresholding can be employed coordinatewise or blockwise, or both, which leads to tests with good power properties under alternative hypotheses that are either sparse or dense.
POWER ANALYSIS ON REPEATED MEASURES DESIGNS

A simulation study comparing powers of the multivariate analysis (PROC GLM) with using a mixed model (PROC MIXED) using a variety of covariance structures for various treatment, time, and interaction affect sizes in a repeated measures design is conducted. Type 1 errors are estimated. Powers are estimated for a variety of covariance structures when the actual covariance structure is AR (1). It was found that the estimated powers for treatment effect were all very similar with PROC MIXED with the correct covariance structure having the largest estimated powers. When testing for time and interaction effect, it was found when in doubt that it was better to use a simpler covariance structure. The powers were generally higher in this case than with a more complex covariance structure.
Assessing the Impacts of the GAFTA Agreement on Selected Members' bilateral Agricultural Trade: an Application of the Gravity Model

Trade flows of agricultural commodities have always received a lot of attention in the Arab region, mainly due to their implications on food security, politics and competition. Most international trade theories postulate that free trade regimes have positive effects on bilateral trade. The justification is that regional trade blocks decrease barriers to intraregional trade and hence, member countries are likely to expect some benefits. Whether each member country actually benefits from such agreements is, however, a subject to debate and empirical tests. The gravity model is used in this paper to assess the impact of the Greater Arab Free Trade Agreement (GAFTA), particularly on the volume and pattern of bilateral agricultural trade during the period between 1995 and 2007. Our results reveal that GAFTA did not have the desired effects on the intra-regional volume of bilateral agricultural trade in four out of eight member countries selected for this study. The only countries in the sample that exhibited positive effects in both the import and export sectors are Lebanon and Syria. These findings uncover important facts that are hidden in the results of other studies, which concluded that the GAFTA has led to an increase in total intra-regional volume of trade. The current study adds to the literature by looking at the effects of the agreement on individual member countries' bilateral trade rather than the aggregate volume of intraregional trade.
Temperature measurement of cryogenic nitrogen jets at supercritical pressure

The temperatures of transcritical and supercritical nitrogen jets were measured to explore the influence of “pseudovaporization” upon cryogenic propellant mixing in high-pressure rocket chambers. Pseudovaporization is the large thermodynamic transition near the pseudocritical temperature under transcritical conditions, which can include a drastic density change and large peak of isobaric specific heat. A decline in the rise of temperature along the jet centerline of the transcritical jet was caused at the position where the local temperature reached nearpseudocritical temperature. This can be considered to be due to the large peak of isobaric specific heat. The density jump appeared near the pseudocritical temperature, which can be correlated to the sudden expansion due to pseudovaporization. The axial profiles of the temperature and density of the supercritical jet monotonically increased and decreased, respectively, in the downstream region of the end of the jet potential core. Similar to the axial profiles, the radial profiles of the temperature were influenced by the pseudovaporization − i. e. , the temperature rise in the radial direction became very shallow in the region where the local temperature was still lower than the pseudocritical temperature. The full width at half maximum of the density profiles stayed almost constant further downstream of the end of the jet potential core, whereas that of the mass fraction profiles of the incompressible variable-density jet began to increase near the end of the potential core. Hence, the evolutions of jet mixing layers of transcritical jets and variable-density jets can be considered to differ due to pseudovaporization.
