Microporous zeolites are aluminosilicates composed of silicon, aluminum, and oxygen in a framework with cations. The cation contents can be exchanged with metal ions in order to add antimicrobial (antibacterial, anticandidal, and antifungal) properties. Zeolites has also recently been acquainted with fragrance applications to tailor products with controlled release properties. Here, a new application of ion exchanged zeolite X combined with adsorption properties is presented. In this study, zeolite X crystals were ion-exchanged with Zn2+ and Cu2+ ions and encapsulation of a fragrance molecule, triplal, was studied using ion-exchange . . .d zeolite X as a fragrance carrier. The antimicrobial behavior of ion-exchanged zeolite X before and after encapsulation were investigated by disc diffusion method. Zn2+ and Cu2+ loaded zeolite samples showed excellent antimicrobial activities against three bacteria Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa, a yeast Candida albicans and a fungus Aspergillus niger. Ion-exchanged zeolite X samples containing triplal sustained antimicrobial activities after the encapsulation process. © 2016 Elsevier Inc Daha fazlası Daha az

Apart from the studies that focus on public attitudes toward higher courts in advanced democracies, we know little about the factors that can explain public confidence in the judiciary in a comparative setting. In this regard, the goal of this study is to explain whether, and to what extent, the country's level of democracy moderates the impact of political awareness on public confidence in the judiciary. This study uses hierarchical linear models to analyse the interaction between individual and country level factors by using the World Values Survey (2005–2009) data for 49 countries and various other data sources. Our empirical res . . .ults show that in advanced democracies political awareness variables like education and political participation have a positive impact on public confidence in the judiciary, whereas in countries with weak levels of democracy higher political awareness leads to increased cynicism about the judiciary. These results suggest that a one-size-fits-all approach to explain confidence in the judiciary is not possible when we are dealing with a wide range of societies that vary in terms of many characteristics, both institutional and cultural. © 2015 Taylor & Francis Daha fazlası Daha az

We conducted a cross-sectional study to assess vocal and swallowing functions after horizontal glottectomy. Our study population was made up of 22 men aged 45 to 72 years (mean: 58.3) who underwent horizontal glottectomy and completed at least 1 year of follow-up. To compare postoperative results, 20 similarly aged men were included as a control group; all glottectomy patients and all controls were smokers. We used three methods-acoustic and aerodynamic voice analyses, the GRBAS (grade, roughness, breathiness, asthenicity, and strain) scale, and the voice handicap index-30 (VHI-30)-to assess vocal function objectively, perceptually, . . . and subjectively, respectively. We also assessed swallowing function objectively by fiberoptic endoscopic evaluation of swallowing (FEES) and subjectively with the M.D. Anderson dysphagia inventory (MDADI). The 22 patients were also subcategorized into three groups according to the extent of their arytenoid cartilage resection, and their outcomes were compared. Acoustic and aerodynamic analyses showed that the mean maximum phonation time was significantly shorter and the fundamental frequency was significantly lower in the glottectomy group than in the controls (p = 0.001 for both), and that the mean jitter and shimmer values and the mean harmonics-to-noise ratio were all significantly higher (p = 0.001 for all); there were no significant differences among the three arytenoid subgroups. Self-assessments revealed that there were no statistically significant differences among the three subgroups in GRBAS scale scores except for the breathiness score (p = 0.045), which was lower in the arytenoid preservation subgroup than in the total resection subgroup; there were no statistically significant differences among the three subgroups in VHI-30 scores. Finally, swallow testing found no statistically significant differences in FEES scores or MDADI scores. We conclude that horizontal glottectomy caused a deterioration in vocal function, but swallowing function was satisfactory Daha fazlası Daha az

This study was performed for detecting Forficulidae (Dermaptera) species in Malatya and Elazig apricot orchards, between 2007 and 2011. According to our results, Forficula auricularia L.1758, F. lurida Fischer 1853, F. aetolica (Brunner, 1882), and Isolaboides kosswigi (Burr, 1947) were reported in apricot orchards. A total of 244 specimens was collected from all orchards, belonging to 3 species from Elazig, and 4 species from Malatya. Amongst recorded species, F. auricularia harms were found in apricot fruits. In these cities, in terms of density and hazardous, F. auricularia was dominant, however it was estimated that after a whil . . .e F. lurida species would increase its own population. The results of the study; F. lurida, F. aetolica and I. kosswigi were found in their collected fauna for the first time. ©Biharean Biologist, 2016 Daha fazlası Daha az

Nitric oxide (NO) participates in numerous biological processes, such as signalling in the respiratory system and vasodilation in the cardiovascular system. Many metal-mediated processes involve direct reaction of NO to form a metal-nitrosyl (M-NO), as occurs at the Fe2+ centres of soluble guanylate cyclase or cytochrome c oxidase. However, some copper electron-transfer proteins that bear a type 1 Cu site (His2 Cu-Cys) reversibly bind NO by an unknown motif. Here, we use model complexes of type 1 Cu sites based on tris(pyrazolyl)borate copper thiolates [CuII]-SR to unravel the factors involved in NO reactivity. Addition of NO provid . . .es the fully characterized S-nitrosothiol adduct [CuI](?1-N(O)SR), which reversibly loses NO on purging with an inert gas. Computational analysis outlines a low-barrier pathway for the capture and release of NO. These findings suggest a new motif for reversible binding of NO at bioinorganic metal centres that can interconvert NO and RSNO molecular signals at copper sites. © 2016 Macmillan Publishers Limited.

Purpose The purpose of this study was to compare the results of pedobarographic gait analysis between the patients treated by proximal femoral nail or bipolar partial hemiarthroplasty due to intertrochanteric fractures. Methods Thirty-seven patients with a minimum 1-year follow-up who had been operated for intertrochanteric fractures were evaluated clinically, radiologically and with pedobarographic gait analysis. Proximal femoral nail had been performed to 21 patients (group A), whilst 16 patients had been operated by partial bipolar hemiarthroplasty (group B). Pedobarographic analysis was performed by measuring plantar pressure, f . . .orce and contact area values in both static and dynamic manner. Pedobarographic results of operated limb were compared among groups. Same data's also were compared between operated and uninjured limbs in each group to determine any asymmetry on weight-bearing. Results Average follow-up period in group A and group B was 36 (12-56) and 30 (12-48) months, respectively. There were no statistically significant differences among groups in terms of age, gender, body mass index, type and side of fracture, follow-up period, leg length discrepancy and postoperative hip scores. When the pedobarographic results of operated limb were compared, group B showed much more plantar force and pressure values than group A, on both static and dynamic evaluations. If the evaluation was taken into consideration to comparison of pedobarographic results between operated and uninjured limbs in each group, we found asymmetry in static load bearing, caused by higher load on uninjured limb in both groups. However, there was no statistically significant asymmetry between operated and uninjured limbs in respect to dynamic pedobarographic parameters for patients in group A. On the contrary, operated limbs in group B exposed much more plantar force and pressure values than uninjured limbs, which indicated asymmetric weight-bearing on dynamic evaluation. Conclusions Assessment of pedobarographic parameters can be another way of measuring the results of treatment in intertrochanteric fractures. Uninjured limbs of patients expose much more loading than operated limbs in postoperative static evaluation for both treatment options. However in dynamic evaluation, there is a better concordance of gait analysis between both limbs in patients operated by proximal femoral nail. © 2016 Elsevier Ltd.

Purpose: Despite being repeatedly shown that exercise training (ET) increases exercise capacity and decreases mortality in many cardiac conditions, not all patients enjoy the benefits of ET programs. We hypothesized that baseline cardiovascular mechanic properties, including cardiac systolic and diastolic functions, arterial mechanics and ventriculoarterial interaction, may have a role in predicting response to ET. Methods: Full left ventricular pressure-volume loops were constructed and arterial mechanics were evaluated using echocardiographic and tonometric measurements. A cardiopulmonary exercise (CPX) test was performed before a . . .nd after the ET program. Result: Sixty of the 75 patients with coronary artery disease or heart failure diagnoses completed the study. All of the CPX parameters showed a significant improvement with ET. The change in oxygen uptake correlated only with arterial parameters, such as compliance (r=0.399, P=.002), end-systolic arterial elastance (r=- 0.293, P=.02), aortic pulse pressure (r=- 0.302, P=.02), and brachial pulse pressure (r=- 0.312, P=.01). Receiver-operating characteristics analysis demonstrated that baseline arterial compliance and brachial pulse pressure predicted a significantly positive ET result with reasonable sensitivity and specificity. Conclusions: Patients with a more compliant arterial system improved their exercise capacity more with ET. Evaluation of baseline arterial compliance may facilitate proper patient selection and may define patients who need optimizing measures for the arterial system before commencing ET. Even a simple blood pressure measurement may give clues in this regard. © Copyright 2016 Wolters Kluwer Health Daha fazlası Daha az

Background: A deeper understanding of periodontitis pathophysiology is central to future development of novel biomarkers and therapeutics. The following is reported here: 1) an in silico network model of interactions among cell adhesion molecules and a network-focused microarray analysis of the corresponding genes in periodontitis; 2) analysis of secretions of adhesion molecules in gingival tissue samples from patients with periodontitis and healthy controls; and 3) effect of the human neutrophilic peptide-1 (HNP-1) on epithelial adhesion molecules. Methods: The network model identified 85 nodes in relation to the interactions of ad . . .hesion molecules. Subsequently, the relative gene expression was overlaid on the network model. Differential gene expression was analyzed, and false discovery rate control was performed for statistical assessment of the microarray data. Both tissue and cell culture samples were immunostained for desmocollin (DSC)2, occludin (OCLN), desmoglein (DSG)1, tight junction protein 2, and gap junction protein a. Results: The differential gene expression analysis revealed that the epithelial adhesion molecules were significantly lower in abundance in individuals with periodontitis than controls. In contrast, the genes for leukocyte adhesion molecules showed a significant upregulation. Immunostainings revealed elevated secretions of both DSG1 and OCLN in periodontitis. An in vitro model suggested reduced DSC2 and OCLN secretions in the presence of HNP-1. Conclusions: Gene expression of gingival adhesion molecules in periodontitis is regulated by leukocyte transmigration, whereas the neutrophilic antimicrobial peptide HNP-1 is noted as a putative regulator of epithelial adhesion molecules. These observations contribute to the key mechanisms by which future biomarkers might be developed for periodontitis Daha fazlası Daha az

Statement of problem With the development of translucent zirconia, questions regarding the influence of cements on the final color of monolithic zirconia restorations have arisen. Purpose The purpose of this in vitro study was to evaluate color changes in terms of the perceptibility and acceptability of monolithic zirconia-and-cement combinations with 2 monolithic zirconia thicknesses and 3 types of cement. The translucency parameters of these combinations were also compared. Material and methods Sixty monolithic zirconia ceramic disks were milled with 2 different thicknesses (0.6 mm and 1 mm). A conventional glass ionomer cement, a . . . resin-modified glass ionomer cement, and a resin cement from the same manufacturer were applied to the ceramic surfaces of both thickness disks (n=10). Translucencies and color changes of the monolithic zirconia specimens after cement application were examined by using a spectrophotometer, and translucency parameters (TPs) and color changes (?Es) were calculated and statistically analyzed. Results Colors and TPs of the zirconia disks changed significantly after being cemented to 0.6- and 1-mm-thick disks ( Daha fazlası Daha az

An estimate is obtained for the total force exerted on a suspension bridge in a marathon where thousands of people run at varying velocities. A distribution function n(v) is drawn that gives the number of runners n within possible velocity intervals as a function of velocity. Basic dynamical relationships are applied to the video images of some athletes running as models on the same treadmill one at a time (within a range of speeds) and the data of New York Marathon 2005 are used. The average load on such a bridge is also compared with that due to the everyday traffic. © 2016 Physics Essays Publication.
