MODULATOR IMPACTS OF PROPOLIS EXTRACT AGAINST DOXORUBICIN MEDIATED CARCINOGENESIS ON HEPATOCELLULAR CARCINOMA AND Drosophila SOMATIC CELLS

The antitumor action of propolis is of clinical interest because of the need for new anticancer treatment agents. The present investigation intended to extract and assess the chemical content, cytotoxic action, the growth inhibitory activity and anticancer capability of Egyptian propolis versus Chinese propolis. This was carried out using water extract (WE) and ethanolic extract (EE) on the human hepatocellular carcinoma (HEp-2) cell line and the loss of heterozygosity (LOH) assay of Drosophila melanogaster somatic cells against the direct genotoxicity of doxorubicin. EPWE, EPEE, CPWE and CPEE extracts analyzed by HPLC showed that there were sensible and various concentrations of phenolic compounds in both. Total phenolics were determined to be 18.83, 34.87, 39.29 and 180.89 g-1 by using EPWE, CPWE, EPEE and CPEE extracts, respectively. Chinese propolis ethanol extract (CPEE) have major concentrations of total phenolics and phenolic acids and contained high concentrations of rutin (188.90 g/mL). The study of the antiproliferative capacity of propolis extractors against HEp-2 cancer cell lines showed that all the studied propolis extracts induce suppression of cell growth except CPWE extract; it gave 100% cell viability. The great majority of the propolis are strongly cytotoxic against HEp-2 cell line with 500 μg/ml CPEE. Also, PEE is the most effective in inhibition of HEp-2 cell proliferation compared to PWE. In Drosophila assay, treatment with propolis extract and DOX carcinogenic agent led to a reduction in the frequency of recombination compared to the treatment with DOX alone either in the post- and pre-treatments. In general, PEE exhibited powerful anti-proliferative effects than PWE. The ethanol extract provided the highest protection against Doxorubicin (DOR) induced genotoxicity, a fact that supports their anti-cancer activity. The results demonstrate that PEE is a good source of a natural antitumor operator able to inhibit cancer cell proliferation.
A Laurentian margin back-arc: The Ordovician Wedowee-Emuckfaw-Dahlonega basin

Independent researchers working in the Talladega belt, Ashland-WedoweeEmuckfaw belt, and Opelika Complex of Alabama, as well as the Dahlonega gold belt and western Inner Piedmont of Alabama, Georgia, and the Carolinas, have mapped stratigraphic sequences unique to each region. Although historically considered distinct terranes of disparate origin, a synthesis of data suggests that each includes lithologic units that formed in an Ordovician back-arc basin (Wedowee-EmuckfawDahlonega basin—WEDB). Rocks in these terranes include varying proportions of metamorphosed mafi c and bimodal volcanic rock suites interlayered with deep-water metasedimentary rock sequences. Metavolcanic rocks yield ages that are Early– Middle Ordovician (480–460 Ma) and interlayered metasedimentary units are populated with both Grenville and Early–Middle Ordovician detrital zircons. Metamafi c rocks display geochemical trends ranging from mid-oceanic-ridge basalt to arc affi nity, similar to modern back-arc basalts. The collective data set limits formation of the WEDB to a suprasubduction system built on and adjacent to upper Neoproterozoic– lower Paleozoic rocks of the passive Laurentian margin at the trailing edge of Iapetus, specifi cally in a continental margin back-arc setting. Overwhelmingly, the geologic history of the southern Appalachians, including rocks of the WEDB described here, indicates that the Ordovician Taconic orogeny in the southern Appalachians developed in an accretionary orogenic setting instead of the traditional collisional orogenic setting attributed to subduction of the Laurentian margin beneath an exotic or peri-Laurentian arc. Well-studied Cenozoic accretionary orogens provide excellent analogs for Taconic orogenesis, and an accretionary orogenic model for the southern Appalachian Taconic orogeny can account for aspects of Ordovician tectonics not easily explained through collisional orogenesis. *barineau_clinton@columbusstate.edu; jtull@fsu.edu; cholm-denoma@usgs.gov Barineau, C.I. , Tull, J.F. , and Holm-Denoma, C.S. , 2015, A Laurentian margin back-arc: The Ordovician Wedowee-Emuckfaw-Dahlonega basin, in Holmes, A.E. , ed., Diverse Excursions in the Southeast: Paleozoic to Present: Geological Society of America Field Guide 39, p. 21–78, doi:10.1130/2015.0039(02).

Is it contagious? An eye-movement and EMG study of smile authenticity judgment

A smile is commonly used to mask negative emotions, yet those emotions are often leaked through microexpressions. These microexpressions act as brief displays of the individual’s true emotion. Studies have indicated that participants often have difficulty judging the emotional expressions as truly happy or not truly happy, even when the leaked emotion is displayed for extended periods of time. The current study used a smile authenticity judgment task and sought to understand why individuals have difficulty with these non-authentic smiles (i.e. masking smiles; angry brow, angry mouth, disgust, fear, sad brow, and sad mouth). Various judgment strategies were evaluated, such as explicit knowledge, attentional limitations (eyemovement measures), emotional contagion (scale; ECS), and facial mimicry (electromyography; EMG). Accuracy results were observed to be a function of emotional expressions, where participants are more accurate with masking smiles containing fear and less accurate with masking smiles containing anger in the brows. In addition, judgment strategies appear to be a function of emotion. For instance, emotional contagion and facial mimicry were respectively significant predictors of fear and angry mouth masking smile judgment accuracy. Alternatively, attentional limitations were a significant predictor of angry brow masking smile judgment accuracy. In sum, smile authenticity judgment of masking smiles and their respective strategies appear to be as a function emotion.
Fishery Resources and Trade Openness: Evidence from Turkey

There is an ongoing debate over the potential effects of international trade on fishery resources. In this study, we investigate whether the trade in fish and fish products contributed to the decline in a given number of fish species in Turkey. The overall purpose is to test the theoretical findings of Brander and Taylor (1997) who argue that trade openness decreases fish harvest in a small open economy characterized by a regime of open-access to fishery resources. To this end, we estimate a panel data model to measure the effects of trade openness on fish harvests in the case of 57 fish species observed from 1996 to 2009 in Turkey. We estimate Turkish fish harvests in terms of the relative importance of openness to trade as well as in terms of biological characteristics, in addition to economic and technological factors. Estimation results reveal a backward-bending supply curve for the fish harvest. Furthermore, we find that the indicator of openness to trade has a significant and positive impact on the fish harvest. Our results suggest that further openness to trade would put additional pressure on Turkey’s already declining fishery resources.
Cleaner fish Labroides dimidiatus reduce 'temporary' parasitic corallanid isopods on the coral reef fish Hemigymnus melapterus

To determine if cleaners affect 'temporary' parasitic corallanid isopods (Argathona macronema) on fish, we used caged fish Hemigymnus meldpterus (Labridae) on 5 patch reefs on Lizard Island, Great Barrier Reef, and removed all cleaner fish Labroides dimidiatus (Labridae) from 3 of the reefs, In a short-term experiment, fish were sampled after 12 or 24 h, at dawn and sunset respectively, and in a long-term experiment they were sampled after 12 d at sunset. Isopod prevalence, abundance and size were measured. In the short-term experiment, on reefs without cleaners the prevalence of A. macronema was higher after 24 h than after 12 h while on reefs with cleaners, prevalence was low at all times, Although the abundance of A, macronema did not vary after 12 and 24 h, when combined over the 24 h, the effect of cleaners was significant with only 2 % of all the A. macronema found on reefs with cleaners. Cleaners had no effect on the size frequency distribution of A. macronema in the short-term experiment, most likely because fish had so few isopods on reef with cleaners. In the longer-term experiment, the effects of cleaners on isopod prevalence and abundance were less clear. Their effect on isopod size was, however, significant with smaller parasites on reefs without cleaners. The reduction of isopod prevalence and abundance by cleaner fish over a period of hours may explain why these A, macronema are rare on wild fish. Our findings support the idea that cleaning is beneficial to clients and has important implications for the control of parasites of fish farmed in cages,
Effect of Changing Ellipiticity Ratio on the Formation of Ultra-Thin Lubricating Film

The mechanism of fluid film lubrication in ultra-thin conjunction under elliptical point contacts is discussed in this paper. The results of changing the ellipticity ratio are highlighted. The operating conditions; load and speed of entraining motion, promote formation of ultra-thin films that are formed under the combined action of Elastohydrodynamic lubrication (EHL), surface contact force of solvation and molecular interactions due to presence of Van der Waals' force. The paper shows that, changing the ellipticity ratio maintain the general behavior of the formation of ultra-thin lubricating film thickness as in the case of circular point contact problem when the contiguous solids are subject to light-to-medium contact loads and the effects of surface forces become significant as the elastic film (i.e. the gap) is reduced to a few nanometers and lubricant discretisation appears. © 2017 Published by Faculty of Engineering Corresponding author: M.F.

Food for the Stomach or Fuel for the Tank: What do Prices Tell Us?

The “food vs. fuel” debate has been difficult to resolve without letting the data speak. In this paper we investigate the short run interactions and the long-run equilibrium relationship between food and fuel prices. Results from cointegration analysis indicate a long-run equilibrium relationships between these prices. A closer examination of the price dynamics between ethanol and three food prices revealed that the corn-soybean linkage plays a key role in the fuel-food long-run relationship. Our results indicate that ethanol prices Granger cause corn prices, while no individual agricultural commodity appears to Granger cause ethanol prices. However, corn and soybean as a single group had a significant impact on the ethanol market.
Influence of Gender on Interest and Academic Achievement of Students in Integrated Science in Obio Akpor Local Government Area of Rivers State

The study looked at the influence of gender on interest and achievement of integrated Science students in Obio Akpor local government area of Rivers State. Two research questions and two hypotheses were raised, the population comprised of all secondary school students in the local government area and a total of 600 students took part in the study. Two instruments were used to collect data: the test scores and a likert scale like interest scale. Mean, standard deviation and t-test were used to analyse the data. The findings showed that gender has a significant influence on the interest but does not have a significant influence on achievement of Integrated Science students. It was recommended: that Integrated Science teachers should teach in such a way as to rouse the interest of the students, students should be self motivated, find joy in learning in order to excel.
What Fuels the Boom Drives the Bust: Regulation and the Mortgage Crisis

We show that the lightly regulated non-bank mortgage originators contributed disproportionately to the recent boom-bust housing cycle. Using comprehensive data on mortgage originations, which we aggregate at the county level, we first establish that the market share of these independent non-bank lenders increased in virtually all US counties during the boom. We then exploit the heterogeneity in the market share of independent lenders across counties as of 2005 and show that higher market participation by these lenders is associated with increased foreclosure filing rates at the onset of the housing downturn. We carefully control for counties’ economic, demographic, and housing market characteristics using both parametric and semi-nonparametric methods. We show that this relation between the pre-crisis market share of independents and the rise in foreclosure is more pronounced in less regulated states. The macroeconomic consequences of our findings are significant: we show that the market share of these lenders as of 2005 is also a strong predictor of the severity of the housing downturn and subsequent rise in unemployment. Overall our findings lend support to the view that more stringent regulation could have averted some of the volatility on the housing market during the recent boom-bust episode.
The Taurus Molecular Cloud: Multiwavelength Surveys with XMM-Newton, the Spitzer Space Telescope, and the Canada-France-Hawaii Telescope

The Taurus Molecular Cloud (TMC) ranks among the nearest and best-studied low-mass star-formation regions. It contains numerous prototypical examples of deeply embedded protostars with massive disks and outflows, classical and weak-lined T Tauri stars, jets and HerbigHaro objects, and a growing number of confirmed brown dwarfs. Star formation is ongoing, and the cloud covers all stages of pre-main-sequence stellar evolution. We have initiated comprehensive surveys of the TMC, including in particular (1) a deep X-ray survey of about 5 deg2 with XMM-Newton; (2) a nearto mid-infrared photometric survey of ≈30 deg2 with the Spitzer Space Telescope, mapping the entire cloud in all available photometric bands; and (3) a deep optical survey using the Canada-France-Hawaii Telescope. Each wavelength regime contributes to the understanding of different aspects of young stellar systems. XMM-Newton and Spitzer mapping of the central TMC is a real breakthrough in disk characterization, offering the most detailed studies of correlations between disk properties and high-energy magnetic processes in any low-mass star-forming region, extending also to brown dwarfs in which disk physics is largely unexplored. The optical data critically complements the other two surveys by allowing clear source identification with 0.8" resolution, identifying substellar candidates, and, when combined with NIR data, providing the wavelength baseline to probe NIR excess emission. We report results and correlation studies from these surveys. In particular, we address the physical interpretation of our new X-ray data, discuss the entire young stellar population from embedded protostars to weak-lined T Tau stars and their environment, and present new results on the low-mass population of the TMC, including young brown dwarfs.
Temporal bacterial community dynamics in the coastal northwest Atlantic Ocean

Temporal bacterial community dynamics in the coastal northwest Atlantic Ocean Heba El-Swais Marine microbial communities are essential drivers of globally important processes, including carbon, nitrogen, iron and sulfur cycles. Because these diverse bacteria play crucial roles, understanding the structure of microbial communities across space and time is important. This will allow better comprehension of the earth’s response to global change. In this study, we used 16S rRNA sequencing to investigate the temporal shifts in bacterial community structure in surface communities in a coastal inlet in the Northwest Atlantic Ocean (Bedford Basin). We demonstrated that in the spring the dominant bacterial groups were the Bacteroidetes, particularly Polaribacter and Cytophaga. The nutrient-poor summer is associated with the alpha-proteobacterial oligotrophic lineage SAR11. Alteromonadales and SAR11 characterize autumn, and winter is strongly associated with Gamma-proteobacterial sulfur oxidizers (GSO) group. We have established that bacterial richness is highest in winter, which is consistent with global latitudinal studies of bacteria. We further demonstrated that similarity between surface bacterial communities varied according to different time-scales. We showed that high-frequency sampling can reveal episodic blooms from the rare bacterial biosphere. In summary, we used a multi-scale study to reveal the temporal dynamics of bacterial community structure in the temperate North Atlantic coastal ocean.

THE RELATIONSHIP BETWEEN LEARNING ORIENTATION AND INNOVATION

There has been a growing interest for the learning process in the organizational context, stimulated by the perception that learning and innovation are essential for survival in competitive and dynamic environments. In spite of the number of specific publications on innovation and organizational learning, there is still an empirical gap in combining the issues together. This article investigates the relationship between innovation and organizational learning, considering the construct of learning orientation and its three dimensions: (i) commitment to learning; (ii) shared vision; and (iii) open-mindedness. A theoretical model describing the hypothetical relationships among these constructs was developed and tested using the structural equation modeling technique. The research was applied in the Brazilian Electro-Electronic Industry. Results show an appropriate adjustment of the investigated structural model, which indicates an influence of the learning orientation over the products innovation, and possibly over the competitive advantage in companies involved in learning processes. The results mainly show that the open-mindedness dimension has a stronger relationship with innovation. It indicates that an open-mindedness attitude, associated to the unlearning concept, stimulates the creation of new products and discontinuity of market standards.
Is nostalgia a mixed emotion? Evidence from emotional experience and facial expressions of emotion

The existence of mixed emotions has become a controversial topic in the field of social psychology, and there have been numerous studies over the past few decades in an effort to uncover the truth about mixed emotions (Larsen & McGraw, 2014; Hepper, Ritchie, Sedikides & Wildschut, 2011). One emotion that has been thought to be a mixed emotion is nostalgia (Sedikides, Wildschut, Arndt & Routledge, 2008). Nostalgia has not been very thoroughly studied, and this study seeks to discern what nostalgia is and how it is elicited. In the study, psychology students from the University of Tennessee watched cartoons that were popular in the 1990s and early 2000s and recent cartoons. 68 psychology students watched a total of 7 cartoons: 4 recent, or control, cartoons and 3 nostalgic cartoons. The participants rated the intensity of their happy, sad, neutral, and nostalgic feelings towards the cartoons. In addition, their facial reactions towards the cartoons were covertly recorded and rated as happy, sad, neutral, or nostalgic by independent coders. Participants consistently reported experiencing more happiness, sadness, nostalgia, and mixed emotions after viewing the nostalgic cartoons rather than the non-nostalgic cartoons. Furthermore, coders rated participants as expressing more happiness during nostalgic cartoons than non-nostalgic; however, coders rated participants as expressing more sadness during non-nostalgic cartoons.
Balancing Work and Home: How Job and Home Demands Are Related to Burnout

Utrecht UniversityThe aim of the present study was to make a clear distinction between workand home domains in the explanation of burnout. First, a 3-factor structureof job and home demands was hypothesized, consisting of quantitativedemands, emotional demands, and mental demands. Next, a model was testedthat delineates how demands in both life domains are related to occupationalburnout through work home interference (WHI) and home work interfer-ence (HWI). In doing so, the partial mediating role of WHI and HWI wasexamined. Consistent with hypotheses, empirical support was found for the3-factor structure of both job and home demands as well as for the partialmediating effects of both WHI and HWI. Job demands and home demandsappeared to have a direct and indirect effect (through WHI and HWI,respectively) on burnout.
