The antibacterial activity of low-density polyethylene/adhesive resin (10%)/epigallocatechin gallate (0.03, 0.5, 5, and 10%) extrusion cast films were evaluated against Staphylococcus aureus (gram positive) and Pseudomonas sp. (gram negative) via direct contact and in solid and liquid culture media. The epigallocatechin gallate concentration in the active films was established per the in vitro antibacterial analysis of pure epigallocatechin gallate against S. aureus and Pseudomonas sp. The epigallocatechin gallate migration profile and concentration required to inhibit bacterial growth in broth were determined. In addition, the effects of epigallocatechin gallate and adhesive resin on the mechanical, color, and thermal film properties were investigated. The results indicate that pure epigallocatechin gallate inhibited the growth of both bacteria. However, only the films with 10 wt% epigallocatechin gallate (with and without adhesive resin) induced morphological changes and inhibited the growth of S. aureus (p < 0.05). In addition, the films with 10 wt% epigallocatechin gallate (with adhesive resin) induced morphological changes in Pseudomonas sp. (p < 0.05). The adhesive resin increased the epigallocatechin gallate release rate in the migration profile (p < 0.05). The epigallocatechin gallate and adhesive resin modified the film properties (p < 0.05). Fourier transform infrared analysis indicated hydrogen bonds between the adhesive resin and epigallocatechin gallate. This study demonstrated that epigallocatechin gallate is a potential antibacterial agent and that adhesive resin provides advantages to active films.

Abstract
CD103 (αE integrin) is an important dendritic cell (DC) marker that characterizes functionally distinct DC subsets in mice and humans. However, the mechanism by which CD103 expression is regulated in human DCs and the role of CD103 for DC function are not very well understood. Here, we show that retinoic acid (RA) treatment of human monocyte-derived DCs (MoDCs) increased the ability of the DCs to synthesize RA and induced MoDC expression of CD103 and β7 at the mRNA and protein level. In contrast, RA was unable to induce the expression of CD103 in primary human DCs isolated from the gastric mucosa. Inhibition of TGF-β signaling in MoDCs down-regulated RA-induced CD103 expression, indicating that TGF-β-dependent pathways contribute to the induction of CD103. Conversely, when RA-treated MoDCs were stimulated with live Helicobacter pylori, commensal bacteria, LPS, or a TLR2 agonist, the RA-induced up-regulation of CD103 and β7 integrin expression was completely abrogated. To determine whether CD103 expression impacts DC priming of CD4+ T cells, we next investigated the ability of CD103+ and CD103─ DCs to induce mucosal homing and T cell proliferation. Surprisingly, RA treatment of DCs enhanced both α4β7 expression and proliferation in cocultured T cells, but no difference was seen between RA-treated CD103+ and CD103─ DCs. In summary, our data demonstrate that RA, bacterial products, and the tissue environment all contribute to the regulation of CD103 on human DCs and that DC induction of mucosal homing in T cells is RA dependent but not CD103 dependent.

ABSTRACT
The Abl tyrosine kinase signaling network controls cell migration, epithelial organization, axon patterning and other aspects of development. Although individual components are known, the relationships among them remain unresolved. We now use FRET measurements of pathway activity, analysis of protein localization and genetic epistasis to dissect the structure of this network in Drosophila. We find that the adaptor protein Disabled stimulates Abl kinase activity. Abl suppresses the actin-regulatory factor Enabled, and we find that Abl also acts through the GEF Trio to stimulate the signaling activity of Rac GTPase: Abl gates the activity of the spectrin repeats of Trio, allowing them to relieve intramolecular repression of Trio GEF activity by the Trio N-terminal domain. Finally, we show that a key target of Abl signaling in axons is the WAVE complex that promotes the formation of branched actin networks. Thus, we show that Abl constitutes a bifurcating network, suppressing Ena activity in parallel with stimulation of WAVE. We suggest that the balancing of linear and branched actin networks by Abl is likely to be central to its regulation of axon patterning.
Hemorrhagic Complications during Long-Term Postoperative Warfarin Administration in Patients Undergoing Lower Extremity Arterial Bypass Surgery

Published: January 2017

Lower extremity bypass procedures restore function and prevent amputation in many patients with severe peripheral arterial occlusive disease. The regular postoperative use of aspirin offers the dual benefit of extending bypass patency and patient survival. Previous trials of adjunctive oral anticoagulant therapy with warfarin have infrequently combined warfarin with aspirin. We hypothesized that the addition of oral anticoagulant therapy would further enhance the benefits of aspirin but may increase the risk of clinically important bleeding. Eligible patients ( N = 831) scheduled for elective lower extremity arterial bypass surgery were randomized to receive either warfarin plus aspirin (WA) ( n = 418) or aspirin alone ( n = 413). At monthly intervals, the warfarin dose was adjusted to a target international normalized ratio (INR) of 1.4 to 2.8; both groups received aspirin (325 mg/d). The end point of major hemorrhagic events, defined as intracranial hemorrhage or bleeding that required intervention, is reported, and INR values and compliance with warfarin therapy are presented. Major hemorrhagic events occurred more frequently in the WA group (35 in the WA group vs 15 in the aspirin group; p = .02) during a mean follow-up of 38 months. In the WA group, an intracranial hemorrhage occurred in six patients (two had an INR > 3.0), of whom four died; one subdural hemorrhage occurred in the aspirin group. Transfusions and interventions for bleeding were more frequent in the WA group, as were minor bleeding events. Of the 8,946 INR determinations, 58% were in the target range, whereas a higher value occurred in 10% and a lower value in 32%. Compliance with warfarin was maintained in 65% of the patients after the first year of observation. In patients with elective lower extremity bypass procedures, the postoperative adjunctive use of warfarin with aspirin increased the risk of major hemorrhagic events. Most of these events occurred when the INR was in the target range.

The question remains as to whether patients presenting with aortoiliac occlusive disease (AIOD) or abdominal aortic aneurysms (AAAs) have similar outcomes when concomitant renal artery reconstructions are performed. In this study, we analyzed our experience with simultaneous aortic and renal reconstructions using a retroperitoneal approach. Over a 5-year period, all patients with either AAAs > 5 cm or symptomatic AIOD who were found to have high-grade renal artery stenosis and who underwent aortic reconstructions with concomitant renal revascularization were analyzed through our vascular surgery registry. Morbidity and mortality were quantitatively evaluated. Data were analyzed using the chi-square test. A total of 1,133 patients with AAA ( n = 832) and AIOD ( n = 301) underwent aortic reconstructions. Two hundred thirty-one patients had 283 concomitant renal revascularizations, including bypass, reimplantation, and endarterectomy, for high-grade (> 70%) renal artery stenosis via a left retroperitoneal approach. The mortality rate of AAA repair with and without renal revascularization was 2.3% (4/178) and 1.5% (10/654), respectively, and that of aortobifemoral bypass for AIOD with and without renal revascularization was 5.7% (3/53) and 2.8% (7/248), respectively. Of the 7 deaths in patients requiring aortic and renal reconstructions, 4 occurred in patients with bilateral renal revascularization. Transient renal insufficiency, ischemic colitis, and cardiopulmonary failure occurred in 5.6%, 2.2%, and 9.6% of patients with AAA repair and in 5.7%, 0%, and 9.4% of patients with AIOD. Two patients developed acute occlusion of their renal bypasses; one was successfully revised, whereas the other led to a nephrectomy. In patients with AAAs, AIOD, and high-grade renal artery stenosis, simultaneous aortic and renal reconstructions can be performed through a retroperitoneal approach with a limited and acceptable mortality. With concomitant renal and aortic procedures, patients with AIOD have a higher mortality when compared with those with AAAs, although this difference is not statistically significant.

AbstractMixed nanocrystalline Ce-Zr-O oxides (Ce/Zr = 1 or 7/3) were prepared by modified Pechini route using ethylene glycol solutions of metal salts. Detailed characterization of their real structure and surface properties by X-ray diffraction on synchrotron radiation with the full-profile Rietveld analysis, high resolution electron microscopy with elemental analysis, Raman spectroscopy, UV-Vis and X-ray photoelectron spectroscopy revealed a high homogeneity of cations distribution in nanodomains resulting in stabilization of disordered cubic phase. This provides a high dispersion of NiO loaded on these mixed oxides by wet impregnation, a high reactivity and mobility of oxygen in these catalysts and strong interaction of Ni with support in the reduced state. This helps to achieve a high activity and coking stability of developed catalysts in CH4 dry reforming in feeds with CH4 concentration up to 15% and CH4/CO2 ratio =1.
The influence of social distance on speech behavior: Formality variation in casual speech
Authors: Koppen Kim , Ernestus Mirjam , van Mulken Margot 
Published: January 2017

AbstractAn important dimension of linguistic variation is formality. This study investigates the role of social distance between interlocutors. Twenty-five native Dutch speakers retold eight short films to confederates, who acted either formally or informally. Speakers were familiarized with the informal confederates, whereas the formal confederates remained strangers. Results show that the two types of interlocutors elicited different versions of the same stories. Formal interlocutors (i. e. large social distance) elicited lower articulation rates, and more nouns and prepositions, both indicators of explicit information. Speakers addressing the informal interlocutors, to whom social distance was small, however, provided more explicit information with an involved character (i. e. adjectives with subjective meanings). They also used the wordandmore often as a gap filler or as a way to keep the floor. Furthermore, a small social distance elicited more laughter, interjections, first-person pronouns and direct speech, which are all indicators of involvement, empathy and subjectivity.

Summary
Toxoplasma gondii is considered one of the most successful parasites of humans and animals. The ingestion of viable cysts through the consumption of undercooked pork is recognized as a significant route of human infection with T. gondii. The aim of this study was to investigate the presence of viable parasite in tissues of free-range pigs from the Zasavica Special Nature Reserve. All pigs were of the Mangulica breed, raised in a traditional way. The serological screening was performed using a modified agglutination test (MAT). The isolation of viable T. gondii was attempted by a bioassay of pig heart tissue in mice, while the real-time polymerase chain reaction (qPCR) targeted at the 529 bp repetitive element of T. gondii was used to detect parasitic DNA in digested hearts. Specific antibodies were detected in 12 out of 18 pigs examined. The bioassay was performed for five MAT-positive and one MAT-negative pig, and a total of three isolates were obtained. qPCR was performed for all samples, including one MAT-negative sample that was not bioassayed. The presence of T. gondii DNA was confirmed in all hearts with a positive bioassay as well as in one originating from seropositive and one from seronegative pig whose hearts were not bioassayed. The successful isolation of viable cysts, presence of risk factors (such as older age at the time of slaughter) and increased contact with the environment, along with the great appreciation of Serbian consumers towards home-cured Mangulica’s meat, make this breed worthy of consideration as a potentially important reservoir of human infection.

Summary
The purpose of this paper is to examine the effects of commercial plant growth regulators (PGRs), namely Inict-1 and Incit-5, on the rooting of African violet leaf cuttings (Saintpaulia ionantha H. Wendl.). The production of African violets has grown considerably in recent years, thus it is important to study the most rapid and cost-effective means of mass production. The propagated plant material of the cultivar ‘Nagano’ was treated with Incit-1 and Incit-5. The following parameters were observed: the occurrence of the first root, the number of formed secondary roots and root lengths, the occurrence of the first leaf, and the occurrence of the first flower. The results obtained showed that the use of commercial rooting hormones, namely Incit-1 and Incit-5, exerted positive effects on the duration of rooting, the number of secondary roots formed, and the root lengths of African violets. During the research, it was observed that the rooting durations of all the plants treated with Incit-1 and Incit-5 were 5 days shorter. The results indicate that the plants treated with PGRs necessitate less time to root, less time to produce new leaves, and, consequently, less time to produce flowers.
Evaluation of Environmental Hazard During Shale Gas Exploration Process in Poland in the Years 2012-2014

Published: January 2017

Abstract
This paper is a summary of results of environmental analysis conducted by PGI-NRI, AGH-UST within the monitoring of natural gas prospecting in unconventional deposits. All elements of natural environment were analyzed and on this basis the qualitative and quantitative impact of drilling and hydraulic fracturing of shales could be assessed. Special attention was drawn to the analysis of the physicochemical condition of post-reaction fluids, soil gas in the well pad area and drilling fluids. The results of analysis reveal that prospecting works do not create a significant environmental hazard. Some indices connected, e.g. with the noise climate lightly exceeded permissible values. Nonetheless, if extensive prospecting and production of shale gas are involved, the environmental studies need to be broadened to supplement this report.

Abstract
Tightening of norms for air protection leads to a development of new and significantly more effective techniques for removing particulate matter, SOx and NOx from flue gas which originates from large solid fuel combustion. Recently, it has been found that combinations of these environmental technologies can also lead to the reduction of mercury emissions from coal power plants. Now the greatest attention is paid especially to the coal power plant in Opatovice nad Labem, close to Hradec Kralove. Its system for flue gas dedusting was replaced by a modern type of cloth fabric filter with the highest particle separation efficiency which belongs to the category of BAT. Using this technology, together with modernization of the desulphurisation device and increasing of nitrogen oxides removal efficiency, leads also to a reduction of mercury emissions from this power plant. The University of Hradec Kralove, the Opole University and EMPLA Hradec Kralove successfully cooperate in the field of toxic metals biomonitoring almost 20 years. In the Czech-Polish border region, comprehensive biomonitoring of mercury in bioindicators Xerocomus badius in 9 long-term monitored reference points is done. The values of mercury concentration measured in 2012 and 2016 were compared with values computed by a dispersion model SYMOS′97 (updated 2014). Thanks to modern methods of dedusting and desulphurisation, emissions of mercury from this large coal power plant are now smaller than before and that the downward trends continues. The results indicate that Xerocomus badius is a suitable bioindicator for a long-term monitoring of changes in mercury imissions in this forested border region. This finding is significant because it shows that this region is suitable for leisure, recreation, and rehabilitation.
Variability of Oxygen-Thermal Conditions in Selected Lakes in Poland
Authors: Ptak Mariusz , Nowak Bogumił 
Published: January 2017

AbstractDissolved oxygen in water (DO) is one of the primary parameters determining its quality. It remains in close relation to water temperature. The article presents results of DO and water temperature measurements performed for five stratified lakes in Poland in the years 2007-2014. The measurements were performed with monthly frequency in the summer half-year (May-October) in the deepest place of each of the lakes. The compared data show the complex character of the course of both of the parameters. The analysis of depth profiles revealed the prevalence of a decreasing tendency, or no tendency was recorded - both in the case of DO and water temperature. Due to the incoherent character of the water in the case of stratified lakes, a more detailed comparison was performed, referring to changes occurring in zones developed during summer stratification. It was determined that the temperature of the epilimnion was directly dependent on air temperature, and in all cases it showed an increasing tendency. Simultaneously, along with an increase in temperature, in the majority of cases, DO concentration in the zone decreased. In reference to the waters of the hypolimnion, increasing, decreasing, and no tendencies were recorded. The above distribution is determined by individual factors of the lakes - morphometry, trophic status, groundwater alimentation, etc. Several years of measurements of DO and water temperature in depth profiles of several lakes in Poland constitute valuable information on the current transformations of the environment of this part of Europe. In the future, the information can provide the basis for long-term analyses over the next decades, enriching global knowledge on those parameters of key importance for water ecosystems.

Abstract
Effects of two combination drying methods as well as two single drying methods on the quality of papaya chips were studied. The longest drying time was found in freeze drying (FD), while the shortest drying time was found in hot-air-explosion puffing drying (HA-EPD). The papaya chips dried by FD exhibited the lowest shrinkage, while the highest shrinkage was found in the hot-air drying (HAD) dried sample. The lowest and highest total color differences (△E) were found in the FD and FD-EPD. The FD dehydrated papaya chips showed the highest retention of ascorbic acid and total carotenoids. The fastest rehydration rate was also observed in samples dried by FD. The worst rehydration capacity was found in FD-EPD, which related to the collapsed porous microstructure. Papaya chips prepared by FD-EPD showed crispier texture, which were in line with their expanded porous microstructures. In conclusion, the application of combining with EPD may improve the retention of nutrition of papaya.
