The success of the modern enterprise depends not only on its ability to develop a good product / service, to form an adequate price and your offer makes available to customers, but also on how to communicate with the target audience. For the management of modern enterprises, including small and medium-sized enterprises (SMEs), is a major challenge that all activities are carried out in a proper manner and that adds value to which the various interested stakeholders. In recent times, are very important, and information and communication systems in the new economy because the rapid technological progress in the ICT sector started the process of creating a new economy, a new growth and economic development. Successful management is increasingly based on interactive communication and the adopting of marketing communication new technologies, all of which contribute to more efficient business for a company.
Hypercompetition & Fiscal Attractiveness
Authors: Rougé Jean-François , Chopov Borislav
Published: February 2017

Hypercompetition is at the very center of modern economies. As a consequence, both states and enterprises have been heavily engaged in an amoral power game (Colonomos, 2005) based exclusively on strength where tax systems have a prominent role. An obscure fiscal war takes place firstly between states seeking to increase their attractiveness. On the other hand, firms fight against states to optimize their revenues. Therefore, the aim of this paper is to discuss the components and the implications of the competition between states expressed through the establishment of tax havens and the launch of merciless fiscal policies. At the same time, enterprises try to shape the existing laws in a manner that favors their interests, using also aggressive fiscal strategies.
The Effects of Bankruptcy on the Predictability of Price Formation Processes on Warsaw’s Stock Market
Authors: Fiedor Paweł , Hołda Artur
Published: February 2017

In this study we investigate how bankruptcy affects the market behaviour of prices of stocks on Warsaw’s Stock Exchange. As the behaviour of prices can be seen in a myriad of ways, we investigate a particular aspect of this behaviour, namely the predictability of these price formation processes. We approximate their predictability as the structural complexity of logarithmic returns. This method of analysing predictability of price formation processes using information theory follows closely the mathematical definition of predictability, and is equal to the degree to which redundancy is present in the time series describing stock returns. We use Shannon’s entropy rate (approximating Kolmogorov-Sinai entropy) to measure this redundancy, and estimate it using the Lempel-Ziv algorithm, computing it with a running window approach over the entire price history of 50 companies listed on the Warsaw market which have gone bankrupt in the last few years. This enables us not only to compare the differences between predictability of price formation processes before and after their filing for bankruptcy, but also to compare the changes in predictability over time, as well as divided into different categories of companies and bankruptcies. There exists a large body of research analysing the efficiency of the whole market and the predictability of price changes en large, but only a few detailed studies analysing the influence of external stimulion the efficiency of price formation processes. This study fills this gap in the knowledge of financial markets, and their response to extreme external events.
Evaluation of the economic viability of forest management by the Forest Experimental Station in Krynica
Authors: Kożuch Anna , Ryś Magdalena
Published: February 2017

The Forest Experimental Station (FES) in Krynica is a unit specialized in teaching activities. However, it also fulfils other educational, ecological and social functions. Additionally, as the FES in Krynica operates on the free market and needs to be competitive, primarily with respect to the raw timber prizes, it is also a forest management unit that can be subjected to economic evaluation. The aim of this study was to analyze the income, costs and overall financial outcome of the FES in Krynica for the years of 2008–2012. A financial analysis, using indicators of financial liquidity, profitability, economic activity and liabilities, was also carried out to evaluate the economic effectiveness and efficiency of the forest management unit’s operation. The data was obtained from financial documents, particularly balance sheets, as well as profit and loss accounts.

In the years of 2008–2012, mean income and costs of the FES in Krynica amounted to 7 121.1 thous. PLN/year and 6 478.2 thous. PLN/year, respectively. The net financial outcome was positive and amounted to a mean of 628.8 thous. PLN/year. The proportion of the sale income compared to the total income from all activities carried out by the unit increased from 93% to 96%. This included income from the sale of products, goods and materials, which increased by 57% mainly due to an increase in the income from timber sales (ca. 83%). Costs incurred by the unit increased as well, being 40% higher in 2012 than in 2008, while the cost level indicator decreased by ca. 8%. In the examined time period, the economic effectiveness and efficiency of the unit’s operation improved, as evidenced by the increasing profits and the values of the profitability indicators.

Results obtained in the comprehensive analysis of the financial situation in the FES in Krynica provide a basis for the evaluation of economic processes and for appropriate decision making concerning wealth management and the direction of future development. In the evaluation of the economic and financial activity of the FES in Krynica, the increase inprofitability in the analysed time period, as concluded from the indicator of turnover profitability, was particularly noteworthy. The financial indicator values greatly exceed reference values only on the level of financial liquidity. The liability indicators served as evidence of obvious financial independence of the FES in Krynica.

Published: February 2017

The abundance and diversity of wood decomposing fungi were investigated by isolating and cultivating filamentous fungi from wood and by detection of fruit bodies of ascomycetous and basidiomycetous fungi. The objective was to study the impact of forest management on fungi in 100-year-old oak and 87-year-old Scots pine forests in Northern Poland. Fungi were found on coarse woody debris of decayed stumps and fallen logs, boughs and branches in each of the three (managed and unmanaged) examined stands. In total, 226 species of Oomycota and fungi were recorded. Oak wood was colonized by one species of Oomycota and 141 species of fungi including Zygomycota (19 species), Ascomycota (103 species) and Basidiomycota (19 species). Scots pine wood was also colonized by one species of Oomycota and 138 species of fungi including Zygomycota (19 species), Ascomycota (90 species) and Basidiomycota (29 species). In the first, second and third stages of decomposition, the oak wood was colonized by 101, 89 and 56 species of fungi respectively and pine wood was colonized by 82, 103 and 47 species respectively. Eighty three of the observed species (37%) occurred on both types of wood, while the other species displayed nutritional preferences. A decrease in the number of species with advancing decay indicates the necessity for a continuous supply of dead wood to the forest ecosystem.

This supply would secure the continuity of fauna and flora and guarantee a stable forest development. The nutritional and ecological preferences of many fungal species furthermore indicate the necessity of supplying the forests with wood of different species.

In commercially managed forests the results obtained here will aid in: (i) the development of strategies for effective dead wood management in the context of forest productivity and future wood stock growth, as well as (ii) finding a compromise between forest management requirements and environmental protection.

Authors: Ribeiro Lucília S. , Órfão José J.M. , Pereira Manuel F.R.
Published: February 2017

Different supported metal catalysts were tested for the one-pot transformation of corncob xylan to xylitol. The influence of several factors, such as catalytic support, nature of metal, metal loading, amount of catalyst, hydrogen pressure and reaction temperature, was investigated. The results revealed that xylan can be converted into xylitol with a yield close to 80% after 2 h of reaction using Ru supported on carbon nanotubes (CNT, 0.4 wt% metal loading) with excellent stability after repeated use, at a temperature of 170°C and an H2 pressure of 50 bar. The yield of xylitol achieved is one of the highest ever reported for the direct conversion of xylan to xylitol using an environmentally friendly process.
Physicochemical Characterization and Thermal Decomposition of Garin Maiganga Coal
Authors: Nyakuma Bemgba Bevan , Jauro Aliyu
Published: February 2017

The paper examined physicochemical and thermal characteristics of the newly discovered Garin Maiganga (GMG) coal from Nigeria. The physicochemical characterization comprised of elemental, proximate, calorific value, and classification (rank) analyses. Thermal analysis was examined using combined Thermogravimetric (TG) and Derivative Thermogravimetric analyses (DTG). Hence, the coal was heated from 30°C to 1000°C at 20°C/min under inert conditions to examine its thermal degradation behaviour and temperature profile characteristics (TPC). The results indicated that the GMG coal fuel properties consist of low Ash, Nitrogen, and Sulphur content. Moisture content was > 5%, Volatile Matter > 50%, Fixed Carbon > 22%, and Heating Value (HHV) 23.74 MJ/kg. Based on its fuel properties, the GMG coal can be classified as a Sub-Bituminous B, non-agglomerating low rank coal (LRC). The GMG coal TPCs – onset, peak, and offset temperatures – were 382.70°C, 454.60°C, and 527.80°C, respectively. The DTG profile revealed four (4) endothermic peaks corresponding to loss of moisture (drying), volatile matter (devolatization), and coke formation. The residual mass Rm was 50.16%, which indicates that higher temperatures above 1000°C are required for the complete pyrolytic decomposition of the GMG coal. In conclusion, the results indicate that the GMG coal is potentially suitable for future utilization in electric power generation and the manufacture of cement and steel.
The Distribution of Macro- and Micronutrients in Maize Within Separated Digestate Fertilizing (Digestate Fibre and Digestate Luquor): Field Trial
Authors: Kodymová Jana , Švehláková Hana , Kyncl Miroslav , Bártková Magdaléna
Published: February 2017

Along with the current increase in the number of biogas plants, huge amounts of digestate, i.e. waste products, are being generated. The common practice in the Czech Republic is to plough the digestate into the land. In our field trial, we compared the fertilizing effects of standard fertilizers applied in the Czech Republic with digestate as the only fertilizer (e.g. digestate fibre and digestate liquor) in real agricultural conditions to find out whether a comparable amount of nitrogen is used in accordance with European legislation. The impact of separated digestate fibre and separated liquor on the soil fertility and quality was observed on the basis of the distribution of macro- and micronutrients in maize. The evaluation of growth increments in maize suggests that the fertilizing effects of digestate liquor or digestate fibre do not match the standard fertilizer in agriculture, but especially digestate liquor is comparable with other mineral fertilizers. Our field trial also shows that digestate liquor is a better fertilizer than digestate fibre, which may be explained by more appropriate ratios of available nutrients in digestate liquor. Digestate fibre may be recommended mainly for the aeration of clayey soil, but is not sustainable as fertilizer.

Resource Monitoring for Wireless Sensor Networks using ANFIS
Authors:   Nagesha, Manvi Sunilkumar S.
Published: February 2017

Wireless sensor networks (WSNs) are usually a resource constrained networks which have limited energy, bandwidth, processing power, memory etc. These networks are now part of Internet by the name Internet of Things (IoT). To get many services from WSNs, we may need to run many applications in the sensor nodes which consumes resources. Ideally, the resources availability of all sensor nodes should be known to the sink before it requests for any further service(s) from the sensor node(s). Hence, continuous monitoring of the resources of the sensor nodes by the sink is essential. The proposed work is a framework for monitoring certain important resources of sensor network using Adaptive-Neuro Fuzzy Inference System (ANFIS) and Constrained Application Protocol (CoAP). The ANFIS is trained with these resources consumption patterns. The input to ANFIS is the resources consumption levels and the output is the resources consumed levels that needs to be sent to the sink which may be individual or combinations of resources. The trained ANFIS generates the output periodically which determines resources consumption levels that needs to be sent to the sink. Also, ANFIS continuously learns using hybrid learning algorithm (which is basically a combination of back propagation and least squares method) and updates its parameters for better results. The CoAP protocol with its observe option is used to transport the resource monitoring data from the sensor nodes to the cluster head, then from the cluster head to the sink. The sensor nodes runs coap server, the cluster head runs both coap client and server and the sink runs coap client. The performance of the proposed work is compared with LoWPAN network management protocol (LNMP) and EmNets Network Management Protocol (EMP) in terms of bandwidth and energy overheads. It is observed that proposed work performs better when compared to the existing works.
The two walking candles in James Joyce’s Ulysses
Authors: Kikuchi Shigeo
Published: February 2017

Following the theory of textual thematization at the level of fictional narrative discourse (Kikuchi 2001, Lose heart, gain heaven: The false reciprocity of gain and loss in Chaucer’s Troilus and Criseyde. Neuphilologische Mitteilungen CII(4). 427–434; 2001, Unveiling the dramatic secret of “Ghost” in Hamlet.

Philologia 10. 61–72; 2013, Poe’s name excavated: The mediating function and the transformation of discourse theme into discourse rheme. Language and Literature 22(1). 3–8), this article examines how Stephen Dedalus and Leopold Bloom in James Joyce’s Ulysses are walking representations of “two candles” set at the head of a dying Dublin. This is one instance of a grand design which is repeated in many of his novels. In “The Sisters”, the first short story in Dubliners and the earliest work in which the grand design can be seen, the two candles are verbally placed at the head of the novel. Later in the story, this design reappears in the house of a dead priest where his two sisters, like the two candles, are holding a wake for him. In Ulysses, Dedalus and Bloom, after roaming through Dublin, stand side by side urinating outside Bloom’s house, like candles offered for one who has crossed the border from old life to new life. This scene presages Molly’s free flowing stream of consciousness in the last chapter, in which her thoughts flow across the syntactic demarcations between utterances, as if symbolizing the dissolution of borders. I shall discuss Joyce’s underlying intent in Ulysses by assuming that the stages in which Dedalus and Bloom roam through Dublin and then urinate together are the theme or topic, and that the demarcation-crossing of Molly’s stream of consciousness, namely, the resolution of the demarcation between the two distinct entities as represented by the two candles, is the rheme or comment on this theme.
Attitudes towards Collaboration in Multicultural Teams in the opinion of Polish and Chinese Students
Authors: Ziemiański Paweł , Stankiewicz Katarzyna
Published: February 2017

The main goal of this paper is to present results of research that addresses the issue of attitudes towards working in both multicultural and single culture teams among Polish and Chinese students. The relationship between those attitudes and factors that includes individual experiences of research participants as well as characteristics of team tasks was analyzed. The research was conducted with students of one Polish and one Chinese technical university as participants. Research findings indicate that there are several important similarities as well as differences in preferences of two analyzed groups. The most important differences pertain to stronger preference of Polish students towards working in a single-culture team when the task requires assuming responsibility, trust and mutual understanding of team members. Additionally, the declared level of experience in single-culture and multicultural team was differently related with preferences towards these two kinds of team among Polish and Chinese participants. Obtained results may be utilized in order to develop recommendations for effective educational efforts aimed at developing multicultural teamwork competencies of future managers and specialists from both of these countries.

Non-HDL-cholesterol and C-reactive protein in children and adolescents with type 1 diabetes
Authors: Prado María Mercedes , Carrizo Teresita , Abregú Adela Victoria , Meroño Tomás
Published: February 2017

Background:

To what extent high sensitivity C-reactive protein (hsCRP) is associated with known cardiovascular risk factors in children with type 1 diabetes (T1D) has not been fully explored.

Methods:

Forty-two T1D children (age: 12+/−1 years) without hypertension, retinopathy, hypothyroidism, albuminuria or other endocrine diseases and 20 controls were studied. Out of the 42 T1D patients studied 57% were prepubertal or early pubertal (Tanner I/II), 38% were pubertal (Tanner III/IV) and 5% post-pubertal (Tanner V).

Results:

Children with T1D showed higher hsCRP than controls [0.51 (0.31–1.71 vs. 0.20 (0.20–0.90) mg/L, p<0.05]. However, hsCRP levels were not different in subgroup analysis [hemoglobin A

Conclusions:

Non-HDL-cholesterol might be more useful than hsCRP to evaluate future cardiovascular risk in children with T1D.

Published: February 2017

Background:

Malnutrition is reported in pediatric neuromotor disability and impacts the child’s health. We described the nutritional and metabolic status in neurologically impaired (NI) children undergoing surgery.

Methods:

Anthropometry, body composition, hormonal and nutritional evaluations were performed in 44 NI subjects (13.7±8.0 years). Energy needs were calculated by Krick’s formula. Metabolic syndrome (MS) was defined applying the following criteria (≥3 defined MS): fasting blood glucose >100 mg/dL and/or homeostasis model assessment for insulin resistance (HOMA-IR) >97.5th percentile, trygliceride level >95th percentile, high-density lipoprotein (HDL)-cholesterol level <5th percentile, systolic/diastolic pressure >95th percentile; whilebody mass index – standard deviation score (BMI-SDS) <2 and biochemical malnutrition markers (≥2) defined undernutrition.

Results:

Energy intake was not adequate in 73.8% of the patients; no correlation between energy intake and BMI was noted. Undernutrition was noted in 34.1% of patients and MS in 11.36% of subjects. Fifty percent of the patients presented with insulin resistance, which was not related to BMI, body composition or other MS components.

Conclusions:

Nutritional and metabolic monitoring of disabled children and young adults is recommended to prevent adverse outcomes associated with malnutrition.

Long-term changes in the trophic state of Suwalki lakes – an analysis by means of indices based on abundance and composition of their rotifer fauna
Authors: Ejsmont-Karabin Jolanta , Górniak Andrzej , Jekatierynczuk-Rudczyk Elżbieta , Karpowicz Maciej , Więcko Adam
Published: February 2017

Rotifer abundance and species composition in lakes of the Suwalki Landscape Park were studied in the years 1983–1985, 2009, 2012 and 2015. Rotifer trophic state indices (TSIROT) were used to assess changes in the trophic state of the studied lakes. In most lakes of the Suwalki Landscape Park, there were no changes in rotifer communities over the 25–32 year period to indicate a decline in trophy of the lakes. However, in lakes with the strongest decline in TSIROT values, the values of indicative parameters widely varied in 2015, which may indicate that the status of rotifer communities in the lakes may be dependent on non-trophic factors.
The variability of summer phytoplankton in different types of lakes in North East Poland (Suwałki Landscape Park)
Authors: Karpowicz Maciej , Górniak Andrzej , Więcko Adam , Cudowski Adam
Published: February 2017

This study describes summer phytoplankton communities in 27 lakes in the Suwałki Landscape Park (SLP) using in situ fluorescence methods. Low chlorophyll-aconcentrations were noted in most of the studied lakes, particularly in the deepest lakes with highest surface area. Green algae, diatoms and cryptophyta were dominant components of lake phytoplankton. Higher chlorophyll-aconcentrations in the shallow or more eutrophicated lakes were connected with an increase of cyanobacteria and cryptophyta concentrations as well as with a decrease in the share of diatoms inphytoplankton structure. Vertical distribution of phytoplankton in stratified lakes revealed the presence of deep chlorophyll layers just below the thermocline where the maximum concentrations of phytoplankton were up to 15 times higher than in the epilimnion zone. The deepest maximum concentration of phytoplankton was noted at a depth of 16.5 metres in Lake Jeglówek. In some lakes two or three significant increases of phytoplankton concentration in the vertical profile were observed, caused by intensive development of different algae groups.

Published: February 2017

Novel trends and concepts in the design and fabrication of vertical cavity surface-emitting lasers (VCSELs) and their integration in optical networks and implementation in integrated photonics applications are discussed. To serve these goals and match the growing bandwidth demands, significant changes are to be implemented in the device design. New lateral leakage-mediated single-mode VCSELs, including both devices confined by oxide layers and those confined by alloy-intermixed regions, are likely to be good candidates for light sources for the data networks of the future. An overview of the records in VCSEL transmission distances and transmission speeds is discussed in this context.

Published: February 2017

The objective of the study was to examine the level of perceived stress among the final year students in the full-time Master’s programme at the Department of Physiotherapy of the University School of Physical Education in Wroclaw, and to identify the factors correlating with stress.

The study involved 54 students. The participants were 23 to 28 years of age, 44 of them were women, and 10 men. The level of stress and related factors were evaluated using the Perceived Stress Questionnaire (KPS - Kwestionariusz Poczucia Stresu) created by Mieczysław Plopa and Ryszard Makarowski, and a short questionnaire prepared by the authors of the study, containing questions about the students’ age, gender, physical activity, financial situation, gainful employment, mode of studies, hometown, having a close friend or relative, plans for the future and satisfaction with the studies.

Regular physical activity is a factor that positively affects the level of students’ perceived stress. A lower level of perceived stress was also associated with the respondents’ rating of their financial situation as good. The overall mean stress score obtained by the surveyed students is indicative of low stress severity. In the majority of cases, the respondents reported an average level of emotional strain and a low level of external and internal stress. The mean values of overall scores on the stress scale and its subscales were higher for women than for men. However, due to the size of the sample group, the differences cannot be seen as statistically significant.

Regular physical activity and good financial situation impact on reducing the level of perceived stress.

Published: February 2017

The aim of the study was to assess the condition of foot morphological structure of young Disco-Dance dancers compared to their untrained peers.

The research was carried out among professional female Disco-Dance dancers, aged 9 ± 1.07, members of Opole dance groups. The control group consisted of 33 females in the same age range, not subject to regular professional training. The condition of morphological structure of their feet was evaluated with the use of the photogrammetric method.

Status of the dancers’ longitudinal foot arch fit the norm. Considerable toe V varus was observed.

In both groups defective positioning of hallux and toe V was stated. Monitoring morphological architecture of feet of young dancers, especially those entering the adolescence is very important because it will allow for early detection of disorders that may result from excessive stress and enable early prevention measures to be undertaken.

Published: February 2017

Introduction. The aim of this study was to characterise the whole body dynamics and upper and lower joint kinematics during two common fencing steps: the lunge and the fleche. Material and methods. Two male competitive epee fencers were studied. Kinematics data were collected at 120 Hz (BTS Smart system) and ground reaction forces were measured at 120 Hz (Kistler platform). The resultant centre of gravity and end segment velocities were calculated. Temporal events were referenced to the horizontal ground reaction force. Time domain linear joint velocities were extracted. Results. At the whole-body level, the resultant centre of gravity velocity was higher during the fleche (2.64 and 2.89 m/s) than during the lunge (1.94 and 2.21 m/s). At the joint level, the wrist and elbow attained their peak velocities earlier than the proximal joint for both the lunge and the fleche for both athletes. Conclusions. The sequence of peak segmental velocities followed a distal to proximal sequence for both fencing steps.
Comparison of Muscle Strength in Male Combat Sport Athletes
Authors: Buśko Krzysztof
Published: February 2017

Introduction. The aim of the study was to examine differences in muscle strength and topography between judoists, boxers, and taekwondo athletes. Material and methods. Thirteen judoists, 6 boxers, and 7 taekwondo athletes took part in the study. The maximal joint torque of the flexors and extensors of the elbow, shoulder, hip, knee, and trunk were measured under isometric conditions. Results. The absolute and relative joint torque was similar in the three groups except for the absolute strength of the right flexor of the shoulder between the boxers and the taekwondo athletes and judoists (p < 0.01). The sums of the relative joint torque and topography of the joint torque of the right and left upper extremity, lower extremity, and trunk were similar in the groups. A significant difference was observed in the topography of the joint torque of the right upper and lower extremity and of the trunk between the boxers and the taekwondo athletes and judoists (p < 0.01). The topography of the joint torque of the flexors and extensors of the right shoulder was significantly different between the boxers and the taekwondo athletes and judoists (p < 0.01). Conclusions. In martial arts, the training undergone by the athletes and their participation in competitions can be expected to affect their strength. The joint torque was similar in the combat groups examined in this study. Judoists and taekwondo athletes did not differ in muscle topography. Boxers differed from the other two groups only in the contribution of the flexors and extensors of the right shoulder, in the sum of the torques of the right upper and lower limb, and the sum of the torques of the trunk. These results may be due to the characteristics of the discipline and the training methods used.
Interactional Trouble and the Ecology of Meaning
Authors: Sidnell Jack
Published: February 2017

Drawing on the methods of conversation analysis (Sidnell, 2010; Sidnell and Stivers, 2012) and the data provided by recordings of ordinary interaction, in this paper I ask what a radically empirical approach to word meaning might look like. Specifically, I explore the possibility that we might investigate linguistic meaning through a consideration of interactional troubles. That is, when participants in interaction confront apparent troubles of meaning, what do those troubles consist in? What is the missing something that leaves participants in interaction feeling as though they do not understand what another means? Four types of trouble in interaction are discussed: troubles of exophoric or anaphoric reference, troubles of common ground, troubles of lexical meaning, troubles of sense.
Meaning Emergence in the Ecology of Dialogical Systems
Authors: Trasmundi Sarah Bro , Steffensen Sune Vork
Published: February 2017

This article is an empirically based theoretical contribution to the investigation of meaningmaking in the ecology of human interaction and interactivity. It presents an ecological perspective on meaning-making that pivots on how agents pick up information directly in their organism-environment-system; i.e. as an activity that does not presuppose inner cognitive operations. We pursue this line of thought by presenting an analysis of how a doctor and a nurse make a decision about a specific medical procedure (catheterisation) based on meaning-making activity. As we do not see meaning as a linguistic (symbolic) or a cognitive (representational) phenomenon external to an agent/user, but as emergent in coordinated interaction, we zoom in on how the practitioners recalibrate the organism-environmentsystem by shift ing between a multi-agentive mode and an individual mode. We use Cognitive Event Analysis to investigate how the agents oscillate between being a multi-agent-system with shared, tightly coordinated agency and a loosely coupled dialogical system where the individuals bring forth an understanding based on their professional backgrounds and expertise. On this view, an ecological approach to meaning-making takes a starting point in how local interaction is constrained by previous events, emergent affordances in the environment, and real-time inter-bodily dynamics.

Introduction. Both infliximab (IFX) and tacrolimus (Tac) are effective for inducing clinical remission in patients with ulcerative colitis (UC). However, no randomized study has addressed the relative efficacies of IFX and Tac for patients with moderate to severe UC. This study aimed to conduct a retrospective study on the relative efficacy of IFX and Tac in patients with moderate to severe UC, using an inverse probability of treatment weighting (IPTW) technique to adjust background factors statistically. Methods. Between July 2009 and March 2016, data obtained from 122 patients with moderate to severe UC who were treated with either IFX (n = 58) or Tac (n = 64) were analyzed retrospectively. We compared the short-term therapeutic efficacy between the IFX group and Tac group using IPTW technique. Results. The clinical remission rate at 14 weeks after treatment was 37.9% (22/58) in the IFX group and 50% (32/64) in the Tac group, respectively. The efficacy of IFX and Tac for clinical remission rate was not different according to univariate (Odds ratio [OR] 1.64, 95% confidence interval [CI] 0.80-3.37 P = 0.18) and multivariate analyses (OR 2.19, 95% CI 0.85-5.61, P = 0.10). After the background and confounders factors were adjusted by using IPTW based on propensity score, the efficacy of IFX and Tac for clinical remission rate was not differed statistically (OR, 1.483; 95% CI, 0.581-3.785; P = 0.409) Conclusion. IFX and Tac have equivalent short-term efficacies for induction in patients with moderate to severe UC.

Comparative analysis of morphometric characters of small-scaled scorpionfish from the Black Sea (near the southern coast of the Crimea) and from the eastern part of the Adriatic Sea showed significant differences in males and females on thirteen plastic and three meristic characters. These differences may be due to unequal abiotic and biotic habitat conditions, and refer about the geographical variability of the species, indicating the presence of two different populations in the study area.

Protocadherin 15 (PCDH15) is required for mechanotransduction in sensory hair cells as a component of the tip link. Isoforms of PCDH15 differ in their cytoplasmic domains (CD1, CD2, and CD3), but share the extracellular and transmembrane (TMD) domains, as well as an intracellular domain known as the common region (CR). In heterologous expression systems, both the TMD and CR of PCDH15 have been shown to interact with members of the mechanotransduction complex. Thein vivosignificance of these protein–protein interaction domains of PCDH15 in hair cells has not been determined. Here, we examined the localization and function of the two isoforms of zebrafish Pcdh15a (CD1 and CD3) inpcdh15a-null mutants by assessing Pcdh15a transgene-mediated rescue of auditory/vestibular behavior and hair cell morphology and activity. We found that either isoform alone was able to rescue the Pcdh15a-null phenotype and that the CD1- or CD3-specific regions were dispensable for hair bundle integrity and labeling of hair cells with FM4-64, which was used as a proxy for mechanotransduction. When either the CR or TMD domain was deleted, the mutated proteins localized to the stereocilial tips, but were unable to rescue FM4-64 labeling. Disrupting both domains led to a complete failure of Pcdh15a to localize to the hair bundle. Our findings demonstrate that the TMD and cytoplasmic CR domains are required for thein vivofunction of Pcdh15a in zebrafish hair cells.

SIGNIFICANCE STATEMENTTip links transmit force to mechanotransduction channels at the tip of hair bundles in sensory hair cells. One component of tip links is Protocadherin 15 (PCDH15). Here, we demonstrate that, when transgenically expressed, either zebrafish Pcdh15a-cytodomain 1 (CD1) or Pcdh15a-CD3 can rescue the phenotype of apcdh15a-null mutant. Even when lacking the specific regions for CD1 or CD3, truncated Pcdh15a that contains the so-called common region (CR) at the cytoplasmic/membrane interface still has the ability to rescue similar to full-length Pcdh15a. In contrast, Pcdh15a lacking the entire cytoplasmic domain is not functional. These results demonstrate that the CR plays a key role in the mechanotransduction complex in hair cells.

Published: February 2017

The use of opioids during pregnancy has grown rapidly in the past decade. As opioid use during pregnancy increased, so did complications from their use, including neonatal abstinence syndrome. Several state governments responded to this increase by prosecuting and incarcerating pregnant women with substance use disorders; however, this approach has no proven benefits for maternal or infant health and may lead to avoidance of prenatal care and a decreased willingness to engage in substance use disorder treatment programs. A public health response, rather than a punitive approach to the opioid epidemic and substance use during pregnancy, is critical, including the following: a focus on preventing unintended pregnancies and improving access to contraception; universal screening for alcohol and other drug use in women of childbearing age; knowledge and informed consent of maternal drug testing and reporting practices; improved access to comprehensive obstetric care, including opioid-replacement therapy; gender-specific substance use treatment programs; and improved funding for social services and child welfare systems.

Abstract:

Introduction: Hysterectomy is one of the most frequently performed gynecological operations worldwide. Due to patient perceived advantages of technical development laparoscopic hysterectomy has become a widely used method. The attitude of patients, surgeons and service providers to laparoscopic procedures is not uniform, but total laparoscopic hysterectomy has prevailed due to its advantages from other types of laparoscopic hysterectomies. Coagulation of the uterine arteries at their origin during the standardized method of total laparoscopic hysterectomy provides further benefits for this procedure. Aim: Our aim was the presentation of our experience together with a review of the relevant literature. Method: Operations were performed with the coagulation of the uterine arteries at their origin right at the beginning of the procedure. Inclusion criteria were the use of the standardized method, video documentation of the surgery, and pre- and postoperative haemostatus results. Results: Our results confirm that the procedure involves an acceptable operating time that is comparable to that of open abdominal and vaginal hysterectomies, minimal blood loss that is far less than that in open procedures, a much shorter duration of hospitalization and a low complication rate. Conclusion: In skilled hands with proper knowledge of the anatomy the standardized method of total laparoscopic hysterectomy with the coagulation of the uterine arteries at their origin is a safe and reproducible technique which suitably utilizes the advantages of minimally invasive surgery.

Diagnosis and treatment of HBV/HDV infection means for the patient to be able to maintain working capacity, to increase quality of life, to prevent cancer, and to prolong life expectancy, while society benefits from eliminating the chances of further transmission of the viruses, and decreasing the overall costs of serious complications. The guideline delineates the treatment algorithms for 2017 set by a consensus meeting of physicians involved in the treatment of these diseases. The prevalence of HBV infection in the Hungarian general population is 0.5–0.7%. The indications of treatment is based upon viral examinations (including viral nucleic acid determination), determinations of disease activity and stage (including biochemical, pathologic, and/or non-invasive methods), and excluding contraindications. To avoid unnecessary side effects and for cost-effective approach the guideline stresses the importance of quick and detailed virologic evaluations, the applicability of elastography as an acceptable alternative of liver biopsy in this regard, as well as the relevance of appropriate consistent follow up schedule for viral response during therapy. The first choice of therapy in chronic hepatitis B infection can be pegylated interferon for 48 weeks or continuous entecavir or tenofovir therapy. The latter two must be continued for at least 12 months after hepatitis B surface antigen seroconversion. Adefovir dipivoxil is recommended mainly in combination therapy. Lamivudine is no longer a first choice; patients currently taking lamivudine must switch if response is inadequate. Appropriate treatment of patients taking immunosuppressive medications is highly recommended. Pegylated interferon based therapy is recommended for the treatment of concomitant hepatitis D infection.
