Abstract
Lymphedema is a chronic disease with a progressively ingravescent evolvement and an appearance of recurrent complications of acute lymphangitic type; in nature it is mostly erysipeloid and responsible for a further rapid increase in the volume and consistency of edema. The purpose of this work is to present our experience in the minimally invasive treatment for recurrence of lymphedema; adapting techniques performed in the past which included large fasciotomy with devastating results cosmetically; but these techniques have been proposed again by the use of endoscopic equipment borrowed from the advanced laparoscopy surgery, which allows a monoskin access of about one cm.

Published: June 2016

Abstract

Background
To explore the effect of sevoflurane inhalation anesthesia on evoked electromyography monitoring of spinal nerve root in children associated with cerebral palsy.

Methodology
Children with cerebral palsy (n=40) were selected and further divided into 1MAC (minimum alveolar concentration) sevoflurane group and 2MAC sevoflurane group. Following the induction of anesthesia, Nicolet Endeavor-CR16 channel electrophysiological monitor was used to implement three times of successive electrical stimulation with interval of 5 sec at 3.50 mA.

Results
Our results suggested a statistical significance of amplitude retention ratio and latency in the sevoflurane inhalation time (P<0.01), with an interaction effect between the sevoflurane inhalation time and concentration for amplitude retention ratio (P<0.01), while there is no interaction effect between the sevoflurane inhalation time and concentration for latency (P>0.05). Compared to 1MAC sevoflurane group, the amplitude retention ratio of 2MAC sevoflurane group decreased remarkably (P<0.01) and the latency of 2MAC sevoflurane group extended at T3 and T4 (P<0.05 or P<0.01).

Conclusions
In evoked electromyography monitoring of spinal nerve root in children with cerebral palsy, with the increasing of concentration and duration of sevoflurane inhalation, evoked electromyogram retention ratio reduces gradually, latency extends and the retention ratio has more changes than the latency.
CT and MR imaging of the thoracic aorta

Published: June 2016

Abstract
At present time, both CT and MRI are valuable techniques in the study of the thoracic aorta. Nowadays, CT represents the most widely employed technique for the study of the thoracic aorta. The new generation CTs show sensitivities up to 100% and specificities of 98-99%. Sixteen and wider row detectors provide isotropic pixels, mandatory for the ineludible longitudinal reconstruction. The main limits are related to the X-ray dose expoure and the use of iodinated contrast media. MRI has great potential in the study of the thoracic aorta. Nevertheless, if compared to CT, acquisition times remain longer and movement artifact susceptibility higher. The main MRI disadvantages are claustrophobia, presence of ferromagnetic implants, pacemakers, longer acquisition times with respect to CT, inability to use contrast media in cases of renal insufficiency, lower spatial resolution and less availability than CT. CT is preferred in the acute aortic disease. Nevertheless, since it requires iodinated contrast media and X-ray exposure, it may be adequately replaced by MRI in the follow up of aortic diseases. The main limitation of MRI, however, is related to the scarce visibility of stents and calcifications.

Published: June 2016

Abstract
Objective: To examine the expression and function of long non-coding RNA taurine up-regulated 1 (TUG1) in human osteosarcoma cells. Methods: Real-time quantitive PCR was used to detect the transcription level of TUG1 in a series of osteosarcoma cell lines. Knockdown of TUG1 in U2OS cells was carried out by transient transfection of siRNAs. MTT assay was performed to access the cell growth rates. Afterwards, RNA and protein of these cells were extracted to analyze the transfection efficient as well as the expression of other molecules. Results: Compared to the normal cell line, TUG1 exhibited a significant upregulation in osteosarcoma cells. Phenotyping analysis showed the growth-promotion activity of TUG1, since knockdown of TUG1 resulted in declined proliferation. We also found that AKT phosphorylation was impaired after TUG1 was inhibited, suggesting that the AKT pathway was involved in the regulation of TUG1 in U2OS cells. Conclusion: Our data provided evidence that TUG1 was upregulated and acted as a possible oncogene via positively regulating cell proliferation in osteosarcoma cells.

Published: June 2016

Abstract
Among two tracheobronchial forms (local and diffuse) and two parenchymal forms (nodular and alveolar septal) that were reported in previous literature, localized endobronchial amyloidosis is an uncommon disease of unknown cause. Bronchial amyloid deposits can occur as focal nodules or multifocal infiltration of the submucosa. We report the case of a 47-year-old man who had complained of dyspnea and wheezing for 1 month and who had been treated for severe asthma at another hospital. Endobronchial amyloidosis was confirmed by histological examination of the bronchial biopsies.

Published: June 2016

Abstract
Congenital cystic lung lesions are a rare but clinically significant group of anomalies, including congenital cystic adenomatoid malformation (CCAM), pulmonary sequestration, congenital lobar emphysema (CLE) and bronchogenic cysts. Despite the knowledge of these lesions increasing in the last years, some aspects are still debated and controversial. The diagnosis is certainly one aspect which underwent many changes in the last 15 years due to the improvement of antenatal scan and the introduction of 3-D reconstruction techniques. As it is known, a prompt diagnosis has an essential role in the management of these children. The new imaging studies as 3D Volume rendering system are the focus of this paper. We describe our preliminary experience in a case of hybrid lung lesion, which we approached by thoracoscopy after a preoperative study with 3D VR reconstruction. Our final balance is absolutely positive.
Tamil in the temples – Language and religious maintenance beyond the first generation
Authors: Perera Nirukshi 
Published: June 2016

AbstractThis study builds on research into the influence of religion on migrant language maintenance in Australia. In the case of Sri Lankan Tamil Hindus, previous studies have found that religious devoutness has a positive influence on the maintenance of Tamil in the home domain. In the religious domain, an ideology which links the Tamil language to the Tamil Hindu (Saiva) religion works in favour of maintaining Tamil in temple spaces in Australia. However this language-religion ideology is challenged by observations that, for the second generation Sri Lankan Tamil Hindu migrants growing up in Australia, a shift to English and disengagement from the religion is occurring. Through interviews with the leaders of three Tamil Hindu temples, I investigate the roles of different languages in the temples and ask whether the temples are contributing to Tamil language maintenance in the religious domain for the second generation. This paper highlights some of the issues faced by temples in engaging young generations in their heritage language and religion; as well as ways that temples are adapting, in a Western setting, in order to establish the religion for the long-term.
Highly integrated optical phased arrays: photonic integrated circuits for optical beam shaping and beam steering
Authors: Heck Martijn J.R. 
Published: June 2016

Abstract
Technologies for efficient generation and fast scanning of narrow free-space laser beams find major applications in three-dimensional (3D) imaging and mapping, like Lidar for remote sensing and navigation, and secure free-space optical communications. The ultimate goal for such a system is to reduce its size, weight, and power consumption, so that it can be mounted on, e.g. drones and autonomous cars. Moreover, beam scanning should ideally be done at video frame rates, something that is beyond the capabilities of current opto-mechanical systems. Photonic integrated circuit (PIC) technology holds the promise of achieving low-cost, compact, robust and energy-efficient complex optical systems. PICs integrate, for example, lasers, modulators, detectors, and filters on a single piece of semiconductor, typically silicon or indium phosphide, much like electronic integrated circuits. This technology is maturing fast, driven by high-bandwidth communications applications, and mature fabrication facilities. State-of-the-art commercial PICs integrate hundreds of elements, and the integration of thousands of elements has been shown in the laboratory. Over the last few years, there has been a considerable research effort to integrate beam steering systems on a PIC, and various beam steering demonstrators based on optical phased arrays have been realized. Arrays of up to thousands of coherent emitters, including their phase and amplitude control, have been integrated, and various applications have been explored. In this review paper, I will present an overview of the state of the art of this technology and its opportunities, illustrated by recent breakthroughs.

Testing the Performance of Cubic Splines and Nelson-Siegel Model for Estimating the Zero-coupon Yield Curve
Authors: Lorenčič Eva 
Published: June 2016

Abstract
Understanding the relationship between interest rates and term to maturity of securities is a prerequisite for developing financial theory and evaluating whether it holds up in the real world; therefore, such an understanding lies at the heart of monetary and financial economics. Accurately fitting the term structure of interest rates is the backbone of a smoothly functioning financial market, which is why the testing of various models for estimating and predicting the term structure of interest rates is an important topic in finance that has received considerable attention for many decades. In this paper, we empirically contrast the performance of cubic splines and the Nelson-Siegel model by estimating the zero-coupon yields of Austrian government bonds. The main conclusion that can be drawn from the results of the calculations is that the Nelson-Siegel model outperforms cubic splines at the short end of the yield curve (up to 2 years), whereas for medium-term maturities (2 to 10 years) the fitting performance of both models is comparable.

Abstract
The aim of this study was to describe the production biomass and abundance dynamics of the major Baltic calanoid copepods (Acartia spp., Temora longicornis and Pseudocalanus sp.) in the Gulf of Gdansk (the southern Baltic Sea) during a three-year period from March 2010 to December 2012. The data were collected at six stations located in the western part of the gulf. Acartia spp. was the most abundant taxon throughout the study period. The observed differences in the weighted mean depth for the investigated species were >2 m between nauplii and adults of Acartia spp., >5 m between nauplii and adults of Temora longicornis and 3 m between nauplii and younger copepodites of Pseudocalanus sp. The highest values of the secondary production rates were determined for Acartia spp. - almost 17.55 mg C m-2 d-1 (summer 2011), while Temora longicornis reached 3.80 mg C m-2 d-1 in spring 2010 and Pseudocalanus sp. had the highest secondary production values in summer 2011 - about 1.28 mg C m-2 d-1.

Published: June 2016

Abstract
We investigated the frequency of antibiotic resistance of Enterobacteriaceae and the presence of vancomycin-resistance genes in samples taken from the Sea of Marmara, and the Istanbul and Canakkale Straits, Turkey. Different colony-forming bacteria were isolated and identified with the VITEK 2 Compact 30 system. The antibiotic resistance of the isolates was determined by the disc diffusion method. The isolates were tested against amoxicillin, ampicillin, aztreonam, ceftazidime, cefotaxime, cefuroxime, ofloxacin, vancomycin, tetracycline, kanamycin and gentamycin. The presence of vancomycin-resistance genes (vanA and vanB) was also investigated. The level of Enterobacteriaceae species was higher in the Sea of Marmara than in the Istanbul Strait and the Canakkale Strait. Isolates showing resistance to the greatest number of antibiotics were identified from E. coli isolates. The resistance of the selected bacterial isolates were as follows: kanamycin (82%), vancomycin (78%) and ampicillin (60%). Some intermediately vancomycin-resistant Enterobacteriaceae isolates had the vanA gene. This study provides evidence of widespread bacterial resistance to clinically relevant antibiotics in marine environments. It also contributes to the knowledge on the distribution of antibiotic resistance among Enterobacteriaceae and indicates the importance of control measures in domestic water treatment.
Characteristics of Cladophora and coexisting filamentous algae in relation to environmental factors in freshwater ecosystems in Poland
Authors: Pikosz Marta , Messyasz Beata 
Published: June 2016

Abstract
Potential factors affecting the occurrence of filamentous algae include the morphometry of water bodies, the type of substrate and physicochemical conditions of the habitat. This study attempts to describe the individual filamentous algae species recorded in Poland, taking into account the trophic and ecological characteristics based on our own research and available literature data. Filamentous algae attached to the substrate as well as those forming free-floating patches (loose or dense mats) and crusts occur in all types of water bodies. Among the representatives of filamentous algae species, Cladophora have the greatest time-spatial range for they grow abundantly in all types of water bodies. In other parts of Poland, Cladophora species are most common in rivers and shallow lakes. In the typical filamentous algae community, Cladophora, Spirogyra and Oedogonium occur with the highest frequency; Zygnema, Mougeotia, Microspora and Rhizoclonium are also present, but with smaller frequency. According to our studies, distribution of filamentous algae species is correlated with the eutrophic index (PO43
-, N-NO3
-, Chl a), chlorides of anthropogenic origin and TDS.
Growth rates of common pelagic ciliates in a highly eutrophic lake measured with a modified dilution method
Authors: Rychert Krzysztof 
Published: June 2016

Abstract
The growth rates of ciliates estimated under natural conditions with the widely used size fractionation method are much lower than those observed in cultures. However, recent studies performed with a modified dilution method demonstrated that the size fractionation method underestimates the ciliate growth, because it does not remove predators of the same size as the organisms studied. Thus, it is still unresolved whether ciliates are food-limited in different systems and whether their growth rates are indeed lower than those in cultures. This study was conducted in highly eutrophic Lake Gardno using a modified dilution method. Each time, two dilution experiments were performed (around noon and around midnight). Four small, common ciliates from the genera Rimostrombidium, Tintinnidium, Cyclidium, and Urotricha were studied. The first three ciliates demonstrated very high mean diel growth rates exceeding 0.1 h-1, which corresponded well to the highest values reported in the literature for the ciliate growth in cultures at similar temperatures. Tintinnidium sp. demonstrated a diel growth rhythm. Urotricha sp. was sensitive to the experimental procedure, and measurements of its growth were unsuccessful. Concentrations of food particles were analyzed to check whether organisms studied were food satiated.
Determination of the oil spill removal area by oil particle tracking in a harbor
Authors: Yang Shu-Yi , You Xue-Yi 
Published: June 2016

Abstract
The removal of oil spill pollution is an important issue of water environment protection. A hydrodynamic model for the determination of oil spill removal area is proposed based on the Euler-Lagrangian particle tracking method. After the results of flow field simulation are validated by the measured data, the trajectory of oil particles is calculated. The optimal location of oil spill removal area is obtained by comparing the oil removal rate of different removal areas. The current method presents a useful way of locating the optimal oil spill removal area to clean the surface waters.
Assessment of biodiversity and environmental quality using macrozoobenthos communities in the seagrass meadow (Gulf of Gdańsk, southern Baltic)
Authors: Dąbrowska Anna H. , Janas Urszula , Kendzierska Halina 
Published: June 2016

Abstract
This study shows the macrozoobenthic biodiversity and the quality status of the Zostera marina meadow in the Gulf of Gdansk. To our knowledge, this is the first study focused on the assessment of environmental quality based on macrofauna occurring on such a small and specific habitat as a seagrass meadow.
The meadow is dominated by Zostera marina, but also Zanichellia palustris and Potamogeton pectinatus are present. Compared to the soft bottom macrofauna in the southern Baltic, the biodiversity of macrozoobenthos is very high, which is reflected in 33 taxa observed during the whole research, while the mean number of taxa was 12. There were also some taxa found only on the bottom overgrown with vegetation, e.g. Idotea balthica or even taxa that are currently rarely observed in the Gulf of Gdansk, e.g. Gammarus locusta or Gammarus ineaquicauda. Nineteen percent of the stations were classified into the very good quality status and 50% into the good quality status, so the environmental status of this meadow based on the BQI index is assessed as good. Given these results, this is probably one of the best preserved meadows in the southern Baltic.
Esterification of chitosan with L-alanine and a study on their effect in removing the heavy metals and total organic carbon (TOC) from wastewater
Authors: Hefni Hassan H. H. , Nagy Mohammed , Azab Mohammed M. , Hussein Mohammed H. M. 
Published: June 2016

Abstract
In this work, chitosan was modified by the esterification with L-alanine in the presence of H2SO4 as a catalyst to increase the number of amino groups with the aim of increasing the adsorption efficiency. Chitosan (CS) and chitosan-O-alanine (CS-Aln) were characterized and investigated by elemental analysis, Fourier transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD). The results obtained from elemental analysis and IR indicated the presence of sulfuric acid after neutralization as a crosslinker between CS-Aln chains. Also CS-Aln is more amorphous than CS due to the ionic bonds of crosslinker. The removal of three heavy metals (Mn2+, Pb2+ and Al3+) and total organic carbon (TOC) from wastewater by CS and CS-Aln in the batch mode has been studied at different adsorbent dosages, temperatures and contact times. The maximum metal ions removal efficiency using CS achieved 99.6%, 99.1% and 98.9%, respectively, while by using CS-Aln 95.3%, 99.3% and 98.9% were achieved. However, the maximum adsorption capacity of TOC by CS achieved 50 mg/g and 89 mg/g by CS-Aln. The total maximum adsorption capacity of CS-Aln is higher than CS.
Sanctions in Russian Political Narrative
Authors: Leichtova Magda B. 
Published: June 2016

Abstract
In this paper, we borrow the dramaturgical analysis from sociologists and use it to analyze how contemporary Russian elites communicate with the public. It is my goal to analyze the performance of the Russian political elite when presenting the changes caused by the worsening Russo-Western relations over the Ukrainian crisis to the domestic audiences, with focus on the impact of sanctions introduced by the Western countries last year. Which strategies, narratives and symbols remain the same and which are adjusted, erased or newly introduced by the political elite when communicating with the public in order to justify the contemporary situation? We will focus especially on two basic components of the narrative: the symbolic level, particularly the use of history, geopolitics and other symbolic topics to frame the current situation; the pragmatic level, especially adjustment of current strategies and introduction of new plans and partners who will help to manage the new situation. As we will clarify later, our analysis will focus on symbolic arguments used by Vladimir Putin as “the national leader” and pragmatic politics introduced by him as “the president”.
