Effect of laser biostimulation on cell proliferation in the healing of cutaneous surgical wounds in pigs.

The objective of this study was to investigate the effect of low-level laser therapy (LLLT) on the proliferation of epithelial and connective tissue cells in the healing of incised cutaneous wounds in pigs. The experiment was conducted on 12 young pigs divided into four groups. Group I (undamaged skin) and group III (damaged skin) served as control. Group II - pigs with undamaged skin and group IV - pigs with incised wounds in the dorsal area were subjected to laser irradiation. Laser biostimulation was carried out using a CTL 1106 MX semiconductor laser in the continuous wave mode of operation at a wavelength of 810 nm and a maximum output of 100 mW. Following three weeks of observation, skin specimens were collected for histopathological analysis (HE), immunohistochemical detection of PCNA, and determination of apoptosis (TUNEL) and presence of mast cells (toluidine blue staining). Laser irradiation administered at E=8 J/cm for 1 min over a period of three weeks accelerated the proliferation of stratum basale cells, stimulated fibroblast proliferation, increased the number of mast cells in the wound area, and inhibited apoptosis in cells participating in the skin regeneration process.
Comparison between five acellular oxidative potential measurement assays performed with detailed chemistry on PM10 samples from the city of Chamonix (France)

Abstract. Many studies have demonstrated associations between exposure to ambient particulate matter (PM) and adverse health outcomes in humans that can be explained by PM capacity to induce oxidative stress in vivo. Thus, assays have been developed to quantify the oxidative potential (OP) of PM as a more refined exposure metric than PM mass alone. Only a small number of studies have compared different acellular OP measurements for a given set of ambient PM samples. Yet, fewer studies have compared different assays over a year-long period and with detailed chemical characterization of ambient PM. In this study, we report on seasonal variations of the dithiothreitol (DTT), ascorbic acid (AA), electron spin resonance (ESR) and the respiratory tract lining fluid (RTLF, composed of the reduced glutathione (GSH) and ascorbic acid (ASC)) assays over a 1-year period in which 100 samples were analyzed. A detailed PM10 characterization allowed univariate and multivariate regression analyses in order to obtain further insight into groups of chemical species that drive OP measurements. Our results show that most of the OP assays were strongly intercorrelated over the sampling year but also these correlations differed when considering specific sampling periods (cold vs. warm). All acellular assays are correlated with a significant number of chemical species when considering univariate correlations, especially for the DTT assay. Evidence is also presented of a seasonal contrast over the sampling period with significantly higher OP values during winter for the DTT, AA, GSH and ASC assays, which were assigned to biomass burning species by the multiple linear regression models. The ESR assay clearly differs from the other tests as it did not show seasonal dynamics and presented weaker correlations with other assays and chemical species.
Critical success factors for implementing risk management systems in developing countries

A review of published studies on risk management in developing countries reveals that critical success factors for implementing risk management has remained an under-researched area of investigation. This paper is aimed at investigating the perceptions of construction professionals concerning the critical success factors (CSFs) for implementation of risk management systems (IRMS). Survey data was collected from 87 construction professionals from the Iranian construction industry as a developing country. The results indicate that four factors are regarded as highly critical: ‘support from managers’, ‘inclusion of risk management in construction education and training courses for construction practitioners’, ‘attempting to deliver projects systematically’, and ‘awareness and knowledge of the process for implementing risk management’. Assessing the associations among CSFs also highlighted the crucial role of enhancing the effectiveness of knowledge management practices in construction organisations. Study also revealed that parties involved in projects do not agree on the level of importance of CSFs for implementing risk management in developing countries. This study contributes to practice and research in several ways. For practice, it increases understanding of how closely knowledge management is associated with the implementation of risk management systems in developing countries. For research, the findings would encourage construction practitioners to support effective knowledge management as a precursor to higher levels of risk management implementation on construction projects.
Organic selenium supplementation improves growth parameters, immune and antioxidant status of newly received beef cattle

The effects of dietary supplementation with selenium enriched yeast on growth, immune and antioxidant status were assessed on 228 newly received beef cattle. During the adaptation phase (54 days), the animals were housed in 38 pens (19 pens per treatment) and supplemented with 0.32 mg · kg −1 DM of Se as sodium selenite (CTR) or selenium enriched yeast (SeY). At days 0, 19 and 54 the animals were weighed and blood samples were collected from one healthy animal per pen. During the experimental trial, bovine respiratory disease (BRD) occurrence was monitored. Blood antioxidant status, selenium serum concentration, bovine herpesvirus-1 (BHV-1) antibody titer and serum bactericidal activity were determined. Growth performance was improved ( P < 0.05) and BRD occurrence was reduced ( P = 0.06) in SeY group. SeY supplementation increased BHV-1 antibody titre after vaccination, highlighting a positive impact of SeY supplementation on immune system functioning. SeY supplementation improved ( P < 0.01) selenium serum concentration and positively affected antioxidant status, expressed as Kit Radicaux Libres value, that tended to be higher ( P = 0.07) in SeY group, due to Se higher bioavailability. The obtained results suggest that dietary supplementation with organic form of selenium improves growth performance, immune and antioxidant status in newly received beef cattle.
The Ovarian Congestion after âU-74389Gâ Administration in Rats

Object: The possible recessing capacity of the antioxidant drug “U-74389G” was studied in a rat model. It included the evaluation of the mean Ovarian Congestion (OC) lesions after induced ovarian Ischemia-Reperfusion (IR) injury. Methods: The 40 used rats of mean mass 231.875 g were classified at 2 evaluation endpoints: one of 60 min for groups A and C and one of 120 min for groups B and D after reperfusion. The U-74389G was administered only in groups C and D. Results: U-74389G administration non-significantly declined the OC lesions scores by 0.6 mild [-1.208205–0.0082055] (p=0.0832). Reperfusion time non-significantly augmented the OC lesions scores by 0.4 without lesions [0.7678806–0.56788075] (p=0.2860). The interaction of U-74389G administration with reperfusion time non-significantly declined the OC lesions scores by 0.2727273 without lesions [-0.6477081–0.1022535] (p=0.1492). Conclusion: The U-74389G administration presented a no significant short-term recess direction for OC scores without lesions alteration. A more long-term study time or an enhanced U-74389G dose may outcome more significant effects.
Sharks and chum? On the trading in momentum stocks by various investor types

Controlling for the trading activity of more and less sophisticated investors ("sharks" and "chum"), past returns alone no longer predict that future returns will move in the same direction. I.e. momentum seems to be generated through the trading activity of these two groups. I nd that past and current buying pressure of sharks positively relate to current returns; past and current selling pressure from chum positively relate to current returns. This is consistent with sharks being simply better able to identify good investment objects at any point in time; chum naivly go in the opposite direction.
Competitive pressure and arousing television news: a cross-cultural study

In many scholarly writings about journalism, the idea can be found that competitive pressure urges journalists to make news more arousing. This hypothesis was tested in two cultural settings: the Western European culture and the Chinese-dominated culture. A total of 3028 TV news stories from seven different markets, or 12 different news programs, were analyzed on the presence of arousing news characteristics. High competitive pressure at the market level appeared to contribute to the prevalence of arousing news, but this effect was more pronounced in the Chinese-dominated culture than in the Western European culture. Effects of high competitive pressure at the station level were only observed in the Western European culture.
The role of executive compensation in the profitability and corporation's growth

The relationship between executive compensation and corporate performance has been studied in the scope of management accounting through the analysis of forms of compensation and their relationships with the items of accounting features. However, there is still few empirical evidence of the effects of executive compensation in the corporation’s performance. In this way, this communication aims to serve as a starting point for a future research based on a review of the relevant literature, using a multiple linear regression model that aims to highlight how the components of compensation might influence the improvement of profitability and growth indicators of organizations.
Optical communication without photons

We show how communication without a physical system carrying the information from the sender to the receiver can be realized. The main point is that sending the vacuum state is not nothing. This extends the recent work by Salih et al. [Phys. Rev. Lett. 110, 170502 (2013)]
A pairwise comparison of the effectiveness of selected active labour market programmes in Germany

"For Germany, our study estimates average effects of further vocational training, short training and job creation schemes on the employment prospects of participants. We compare participation in each programme with non-participation as well as with participation in one of the other programmes. Outcome variables are cumulated days spent in regular employment during the 3.5 years after programme start as well as the share in regular employment at the end of the observation period. First, our results show rather favourable effects of participation in further vocational training programmes and in short firm-internal training - but not of participation in job creation schemes - on the employment prospects of participants. Second, as a result of shorter lock-in effects, shorter programmes perform mostly better when estimating programme effects on days in cumulated employment. However, regarding shares in regular employment at the end of the observation period, in particular long retraining shows positive effects compared to shorter programmes.

VARIACIÓN ALTITUDINAL ENTRE ESPECIES Y PROCEDENCIAS DE Pinus pseudostrobus, P. devoniana y P. leiophylla. ENSAYO DE VIVERO

Los bosques de pino-encino de la comunidad de Nuevo San Juan, Michoacan, estan dominados por Pinus pseudostrobus, P. devoniana y P. leiophylla. Los patrones de variacion genetica de estas especies no se conocen lo suficiente, particularmente los de P. leiophylla, lo cual limita la creacion de lineamientos para el movimiento de semillas y plantulas para reforestacion y su adaptacion al cambio climatico. Las especies se recolectaron en cuatro o cinco procedencias a lo largo de un transecto altitudinal (1,650 a 2,500 m) para el establecimiento de un ensayo en vivero, con el objetivo de cuantificar la variacion genetica entre y dentro de las especies. La altura de la planta (tres y cinco meses de edad) fue significativamente diferente (P < 0.0001) entre especies. Entre procedencias hubo diferencias significativas para P. devoniana (P < 0.0001) y P. leiophylla (P = 0.0352). La especie P. devoniana mostro un pronunciado patron de crecimiento asociado con la altitud de origen, donde las plantas con mayor crecimiento procedian de una menor altitud. Las poblaciones de P. leiophylla fueron diferentes solo a los tres meses de edad, sin un patron altitudinal estadisticamente significativo. No se encontraron diferencias significativas entre poblaciones de P. pseudostrobus
Model-free bounds on bilateral counterparty valuation

In the last years, counterparty default risk has experienced an increased interest both by academics as well as practitioners. This was especially motivated by the market turbulences and the financial crises over the past years which have highlighted the importance of counterparty default risk for uncollateralized derivatives. The following paper focuses on the pricing of derivatives subject to such counterparty risk. After a succinct introduction to the topic, a brief review of state-of-the-art methods for the calculation of bilateral counterparty value adjustments is presented. Due to some weaknesses of these models, a novel method for the determination of model-free tight lower and upper bounds on these adjustments is presented. It will be shown in detail how these bounds can be easily and eciently calculated by the solution of a corresponding linear optimization problem. It will be illustrated how usual discretization methods like Monte Carlo methods allow to reduce the calculation of bounds to an ordinary finite dimensional transportation problem, whereas a continuous time approach will lead to a general mass transportation problem. The paper is closed with several applications of these model-free bounds, like stress-testing and estimation of model reserves.
Adolescents: Differences in friendship patterns related to gender

Based on a survey of 123 Norwegian students aged 14-15 (grade 10) this article will discuss possible gender differences in peer relations, social position and friendship criteria. The students filled in a questionnaire that included sociometry and questions on friendship criteria, self-esteem and social support. We found significant gender differences. However, boys and girls frequently have the same preferences in peer relationships, but to a different degree. The variance within the gender groups may exceed the variance between them.
Endemism and sexual systems in the evergreen tree flora of the Western Ghats, India

This study reports the endemism and sexual system in the wet evergreen tree flora of the Western Ghats. A total of 656 species from 66 families and 231 genera were listed. This included a gymnosperm family (Podocarpaceae) and a monocot family (Arecaceae). No family was endemic to the Western Ghats, but 352 species (53%) from 43 families and five genera were endemic. Nearly 35% of the families had no endemics. The largest families with endemics were Dipterocarpaceae (92%), Anacardiaceae (84%), Lauraceae (72%), Fabaceae, Rubiaceae and Myrtaceae (68%). The top five contributing families in the tree flora of the Western Ghats were Euphorbiaceae, Lauraceae, Rubiaceae, Myrtaceae and Annonaceae. The 656 species were largely hermaphrodites (57%) followed by dioecious (20%), polygamous (16%) and monoecious species (5%). The rate of dioecy reported in this study (20%) is higher than reports for Puerto Rico (18%) but lower than the Malaysian rainforest (26%). Structurally, like the Neotropical forests, most evergreen forest types of the Western Ghats could be classified into four ensembles. Yet, the Western Ghats had fewer species than other tropical and Neotropical forests. The proportion of endemics in the ensembles of the Western Ghats ranged from 34% (ensemble IV) to 14% (ensemble I).
Mechanism of Low Glycemic Index of Pulses and Pulse- Incorporated Cereal Foods

Jenkins and co-workers have demonstrated that isocarbohydrate diets of lentils and soya beans raised the blood glucose by only 42% and 14% of the values observed after bread ingestion both in non-diabetics and diabetics (1). They proposed that physical factors like dietary fiber and its viscosity (2) and unabsorbable carbohydrate (3) were responsible for the differences observed. Holt and co-workers (4) proposed that the differences observed were not due to malabsorption but were due to delayed gastric emptying and prolonged absorption.
Strategies for Inpatient Bed Management

We consider the problem of partitioning clinical services in hospitals into groups with the goal of efficiently allocating existing inpatient beds. At the strategic level, there are two major possibilities: pooling versus focusing. Pooling the bed capacity allows one to achieve an overall high occupancy level for a fixed number of beds. On the other hand, focusing by dividing the capacity into groups with restricted access may offer increased efficiency and better resource utilization. We first derive a 2-stage approach to address the 3-fold problem: 1) how many groups of services to form; 2) how many beds to allocate to each group; and 3) how to partition services among the groups. Specifically, Stage 1 uses cluster analysis utilizing the similarity principle for possible advantages of economies of scale. Stage 2 then incorporates utility/ benefit functions to optimize the partitions and allocation of beds. To contrast the results, we combine the two stages into a single mixed integer nonlinear program. Three full-scale examples demonstrate the flexibility and diverse application of our framework with managerial insights for different utility optimization goals and queuing systems. The resulting modeling framework is not computationally sensitive to the number of beds, making it more practical for usage by any hospitals.
Quinoline Sorption on Na-Montmorillonite: Contributions of the Protonated and Neutral Species

Dilute aqueous solutions of quinoline were contacted with Na-montmorillonite to elucidate the sorption process of the neutral and protonated species. Sorption occurs via a combination of ion exchange and molecular adsorption and yields S-type isotherms. Exchange between the quinolinium ion (QH+) and Na can be described by means of Vanselow selectivity coefficients and a thermodynamic exchange constant (Kex). Due to the apparent adsorption of the neutral species at high mole fractions (x) of the solid phase, the thermodynamic standard state was defined as 0.5 mole fraction. The selectivity at pH ~4.95 of the QH+ species over Na (at XQH+ = 0.5) was determined to be Kv = 340. At pH ≥ 5.5 surface mole fractions of 0.5 could not be obtained without adsorption of the neutral species. This study suggests that at dilute solution concentrations quinoline is sorbed preferentially as the cation even at pHs ≫ pKa. A critical surface-solution concentration is apparently necessary for adsorption of the neutral species.
Arctic Sea Ice Loss in Different Regions Leads to Contrasting Northern Hemisphere Impacts

To explore the mechanisms linking Arctic sea ice loss to changes in midlatitude surface temperatures, we conduct idealized modeling experiments using an intermediate general circulation model and with sea ice loss confined to the Atlantic or Pacific sectors of the Arctic (Barents‐Kara or Chukchi‐Bering Seas). Extending previous findings, there are opposite effects on the winter stratospheric polar vortex for both large‐magnitude (late 21st century) and moderate‐magnitude sea ice loss. Accordingly, there are opposite tropospheric Arctic Oscillation (AO) responses for moderate‐magnitude sea ice loss. However, there are similar strength negative AO responses for large‐magnitude sea ice loss, suggesting that tropospheric mechanisms become relatively more important than stratospheric mechanisms as the sea ice loss magnitude increases. The midlatitude surface temperature response for each loss region and magnitude can be understood as the combination of an “indirect” part induced by the large‐scale circulation (AO) response, and a residual “direct” part that is local to the loss region.
Diagonal Factorization of Integral Equation Matrices via Localizing Sources and Orthogonally Matched Receivers

A procedure is reported to determine accurate, invertible, block-diagonal factorizations for matrices obtained by discretizing integral equation formulations of electromagnetic interaction problems. The algorithm is based on the combination of localizing source/receiver transformations with orthogonally matched receiver/source transformations. The resulting factorization provides a single, sparse data structure for the system matrix and its inverse, and no approximation is required to convert between the two. Numerical examples illustrate the performance of the factorization for electromagnetic scattering from perfectly conducting elliptical cylinders of different electrical size.
Factors influence consumer's behaviour toward logistics e-waste recycling in Malaysia

E-waste generate are greater than e-waste being disposal by consumer in Malaysia which will contaminate the environment and risking public health as well.Past studies revealed that e-waste can be disposal by three ways such as burning, recycling and put at landfill which recycling are the most appropriate concept to reduce the e-waste in an efficiency and effective manner.Previous studies in reverse logistics article mainly focus on recycling concept from supplier or manufacturer context which lack of study connective between logistics company strategy and consumer behaviour. Total 420 undergraduates from University Utara Malaysia (UUM) were choose as respondents due to their knowledgeable about e-waste, high self discipline and technology generation user via convenience sampling method and data collected will analysis with SPSS version 23.The findings reveal the all the variables such as attitude toward recycling, awareness of environment consequence, perceived social norms, perceived convenience are positives correlated with behaviour toward logistics e-waste recycling in this study.
High potential subsidy of dry-season aquatic fauna to consumers in riparian zones of wet–dry tropical rivers

Abstract Aquatic fauna provide an important subsidy to terrestrial consumers. In the wet–dry tropics, important subsidies from rivers to riparian-zone consumers are expected in the dry season but may vary depending on riparian zone condition. We investigated the potential subsidy of aquatic fauna to consumers in riparian zones in 2 highly seasonal rivers in Australia’s wet–dry tropics. Stable carbon and nitrogen isotopes of invertebrate predators in riparian zones were closely aligned with aquatic invertebrates and emergent adult insects. Further, a considerable proportion (40–50%) of the observed vertebrate fauna in riparian zones were consumers of aquatic fauna, which included fish, crustaceans, inverte-brates, and flying adult insects with aquatic larval stages. For hydrologically disconnected waterbodies, estimates of potential insect emergence and the proportion of vertebrate species (in riparian zones) that consume these insects both increased as indicators of riparian plant regeneration and condition improved. Our findings suggest that aquatic fauna provide important subsidies to terrestrial-zone consumers (both invertebrates and vertebrates) during the dry season, and that these transfers can be moderated by riparian zone condition. The wide home and foraging ranges of some consumers also suggest that the importance of these subsidies may extend far beyond the waterbody of origin. Human activities and climate-driven alteration of flow regimes and riparian zones that reduce the availability of dry-season waterbodies or degrade their riparian zones are likely to have negative impacts on aquatic–terrestrial linkages in these systems.
