          Stronger Together in Lab: Multi-Center and Laboratory Spine Studies are Closer to Publication than Single-Center and Clinical Spine Studies: Snapshot of Annual Meetings of the Spine Society of Europe

          Özcan-Ekşi,Emel,Ece,Canbolat,Çağrı,Ayhan,Selim,Ekşi,Murat,Şakir 대한척추외과학회 2020 Asian Spine Journal Vol.14 No.5

          Study Design: This is a cross-sectional study of literature databases.Purpose: The purpose of this study is to analyze the predictive factors for the publication rates of spine studies.Overview of Literature: Spine research has garnered worldwide interest due to the increased number of spinal disorders in aging population.Methods: We evaluated the abstracts presented at the annual meetings of the Spine Society of Europe between 2009 and 2012. Additionally, we recorded presentation categories, study designs, research types, random assignments of the subjects, single- or multi-center- based methodologies, and significance of the results.Results: We evaluated 965 abstracts, 53.5% of which were published in peer-reviewed journals. Publication rates were significantly higher for oral presentations (62.9%) and prospective studies (61.3%) as compared to the poster presentations (46.7%) and retrospective studies (44.2%), respectively (p <0.001). Clinical studies contributed to about 86.1% of the published abstracts. However, publication rates were significantly higher for laboratory studies as compared to clinical studies (70.1% vs. 50.8%, p <0.001). Multi-center studies were closer to publication than single-center studies (67.1% vs. 52.2%, p =0.009). Our study demonstrated that multi-center studies (odds ratio, 1.81; p =0.016) and laboratory studies (odds ratio, 2.60; p <0.001) are more likely to be published.Conclusions: Multi-center collaborations dedicated to experimental studies in spine research are highly ranked and more likely to be published in peer-reviewed journals.

          Raman Spectroscopy of Fluoropolymer Conformal Coatings on Electronic Boards

          Mirjana,Rodošek,Lidija,Slemenik,Perše,Mohor,Mihelčič,Matjaž,Koželj,Boris,Orel,Başak,Bengű,Onder,Sunetci,Pauli,Pori,Angela,Šurca,Vuk 대한금속·재료학회 2014 ELECTRONIC MATERIALS LETTERS Vol.10 No.5

          Fluoropolymer conformal coatings were applied to electronic boards (EBs) and cured at room temperature or 80°C. The coatings were first deposited on model substrate, i.e. aluminium alloy AA 2024 and tested for their anticorrosion properties with a potentiodynamic polarisation technique. The cathodic current densities ranged from 10−9 - 10−10 A/cm2, approaching the lower current limit after the addition of TiO2 nanoparticles into the formulation. Application of fluoropolymer-based formulation was performed via spray-coating deposition. Examination of the coverage of EBs under UV light, which is commonly used in industry, revealed that some components might not be entirely covered. In the search for other possible analytical tools of coverage with protective coatings, optical microscopy and confocal Raman spectroscopy were investigated.

          Nomadic Proletarians, Populism, and the Total Subsumption under Capital

          Slavoj ?i?ek(슬라보예 지젝) 경희대학교 인류사회재건연구원 2019 OUGHTOPIA Vol.34 No.1

          Can the distinction between proletarians proper (exploited workers) and the nomadic (less than) proletarians be somehow blurred in a new more encompassing category of today's proletarians? From the strict Marxian standpoint, the answer is a resounding NO: for Marx, proletarians are not only “the poor” but those who are, by way of their role in the production process, reduced to subjectivity deprived of all substantial content; as such, they are also disciplined by the production process to become bearers of their future power (the “dictatorship of the proletariat”). Those who are outside the production process – and thereby outside a place in social totality – are treated by Marx as “lumpenproletarians,” and he doesn't see in them any emancipatory potential; he rather treats them with great suspicion, as the force which is as a rule mobilized and corrupted by reactionary forces. Things got complicated with the victory of the October Revolution when Bolsheviks exerted power in a country where not only the large majority of the population were small farmers (and Bolsheviks gained power precisely by promising them land!), but where, as the result of violent upheavals during the civil war, millions of people found themselves in the position (not of classic lumpenproletarians but) of homeless nomads who were not yet proletarians (reduced to the “nothing” of their working force) but literally less-than-proletarians (less-than-nothing). This article will discuss the way in which Beckett and Platonov deal with working class from different perspectives and how their analyses pave a way towards the possibility of radical politics.

          Replacing Soybean Meal (SBM) by Canola Meal (CM) : The Effects of Multi-enzyme and Phytase Supplementation on the Performance of Growing and Laying Quails

          B.,Z.,Sarı?i?ek,?.,Kılı?,A.,V.,Garipo?lu 아세아·태평양축산학회 2005 Animal Bioscience Vol.18 No.10

          In this research, the possibilities of using canola meal (CM) in place of soybean meal (SBM), and also the effects of multi-enzyme and phytase supplementation on the performance of quails were investigated. For this purpose, soybean meal (44% CP), canola meal (37% CP), phytase (produced from Peniophora luci) and multi-enzyme (棺-glucanases, pectinases, cellulases and hemicellulases) were used. CM was used supplying 0, 25 and 50% of CP from SBM and each of the phytase and multi-enzyme blends were added to the each level. This study was conducted with 675 day old quails (Coturnix coturnix Japonica) in 9 groups with 3 replicates including 25 birds (mixed sex) per replicate. Nine isocalaric and isonitrogenous diets were prepared. The effects of enzymes and CM levels were studied with a 3횞3횞3 factorial arrangement for three CM levels (0, 25 and 50%), three treatments (without enzyme, phytase enzyme and multi-enzyme) and three replicates. While the 25% CM level did not affect the liveweight gain 50% CM level decreased the liveweight gain (p<0.05). Multi-enzyme addition to the 50% CM group increased the liveweight gain compared to the other groups (p<0.05). CM levels and enzyme supplementation had no effect on feed consumption, feed conversion ratio, dressing percentage, viability, tibia ash content, Ca and P contents of tibia ash, viscera weight, gizzard weight and length of growth period. While heart weight and liver weight were not affected by CM levels, but they were affected by enzyme supplementation. CM levels and enzyme supplementation did not affect final liveweight, feed consumption, feed conversion ratio, egg yield, egg weight, shell weight and shell index during laying period. The increase in the CM level lightened the colour of the yolk (p<0.05).

          ObjectiveaaThe aim of this study was to investigate whether cortisol and oxidative stress levels and DNA damage differ between individuals who developed PTSD or not following a sexual trauma. MethodsaaThe study included 61 children aged between 5 and 17 years who sustained sexual abuse (M/F: 18/43). The patients were divided into two groups: patients with PTSD and patients without PTSD based, based on the results of a structured psychiatric interview (K-SADS-PL and CAPS-CA). Cortisol, glutathione peroxidase (GPx), superoxide dismutase (SOD), coenzyme Q, 8-Hydroxy-2-Deoxyguanosine (8-OHdG) were all evaluated by the ELISA method. ResultsaaOur evaluation revealed a diagnosis of PTSD in 51% (n=31) of victims. There was no significant difference between the groups with or without PTSD in terms of cortisol, GPx, SOD, coenzyme Q, and 8-OHdG levels. There was no correlation between CAPS scores and GPx, SOD, coenzyme Q, and 8-OHdG levels between patients with or without PTSD. In patients with PTSD, both cortisol and 8-OHdG levels decreased with increasing time after trauma, and there was no significant correlation with cortisol and 8-OHdG levels in patients without PTSD. ConclusionaaAlthough the present study did not find any difference between the groups in terms of 8-OHdG concentrations, the decreases in both cortisol and 8-OHdG levels with increasing time after trauma is considered to indicate a relationship between cortisol and DNA damage.

          This study aims to evaluate biogenic amine levels of bez sucuks (BS) produced with different meat:fat ratios. For this, three BS groups were manufactured with meat:fat ratios of 90:10 (BS10), 80:20 (BS20), and 70:30 (BS30). The pH and water activity values and biogenic amine amounts of sucuk samples were determined during processing and storage periods and the pH values of the initial mixtures of BS samples were in the range 5.51-5.74, decreasing to 4.72-4.94 by the 14th day. The water activity values of BS samples showed significant decreases as a result of the drying stage and reached to range 0.913-0.935 on the 14th day of processing (p<0.05). Although BS10 had the highest tyramine (434.12 mg/kg), histamine (5.69 mg/kg), cadaverine (12.48 mg/kg), putrescine (17.83 mg/kg), 2-phenylethylamine (15.43 mg/kg), and tryptamine (122.41 mg/kg) levels at the end of processing stage (p<0.05), spermine and spermidine levels did not differ between the BS samples due to their utilization of different meat:fat ratios (p>0.05). Similarly, the tryptamine (205.11 mg/kg), putrescine (43.57 mg/kg), and tyramine (766.23 mg/kg) levels of BS10 were higher than BS20 and BS30 samples at the end of storage (p<0.05). The results showed that BS10 with the highest meat ratio had the highest tryptamine, putrescine, and tyramine levels at the end of the processing and storage period.

          In this study, the effects of two different commercial starter culture mixes and processing methodologies (traditional andheat process) on the lipolytic changes of fermented sausages manufactured with turkey meat were evaluated during process-ing stages and storage. Free fatty acid (FFA) value increased with fermentation and during storage over 120 d in all fer-mented sausage groups produced with both processing methodologies (p<0.05). After drying stage, free fatty acid values oftraditional style and heat processed fermented sausages were between 10.54-13.01% and 6.56-8.49%, respectively. Thiobar-bituric acid (TBA) values of traditionally processed fermented sausages were between 0.220-0.450 mg·kg-1, and TBA val-ues of heat processed fermented sausages were in a range of 0.405-0.795 mg·kg-1. Oleic and linoleic acids were predominantfatty acids in all fermented sausages. It was seen that fermented sausage groups produced with starter culture had lowerTBA and FFA values in comparison with the control groups, and heat application inhibited the lipase enzyme activity andhad an improving effect on lipid oxidation. As a result of these effects, heat processed fermented sausages had lower FFAand higher TBA values than the traditionally processed groups.

          Comparison of Obesity Prevalence and Dietary Intake in School-Aged Children Living in Rural and Urban Area of Croatia

          Sara,Sila,Ana,Mo?i?,Pavi?,Iva,Hojsak,Ana,Ili?,Ivan,Pavi?,Sanja,Kola?ek 한국식품영양과학회 2018 Preventive Nutrition and Food Science Vol.23 No.4

          The aim of this study was to explore the differences in nutritional status and dietary intakes in 12∼17 yearold children living in urban (Zagreb) and the rural (Sinj and Drniš) area of Croatia. A validated food frequency questionnaire was used to assess dietary intake. For each participant, body weight and body height were measured and bioelectrical impedance was used to estimate the body fat percentage. There was an overall of 310 children included: 105 (33.9%) from urban area and 205 (66.1%) from rural area; 191 (61.6%) were female with a mean age 14.9 (range 12∼17) years. When adjusted for age and gender, there was no statistically significant difference in body mass index for age Z-scores between urban and rural parts (0.23±0.07 vs. 0.30±1.15; P=0.650) or in average daily energy intake (2,479.2±1,111.2 kcal vs. 2,338.2±920.2 kcal; P=0.702). There was a statistically significant difference in nutritional status between genders, with a higher percentage of boys being overweight or obese compared to girls. When combined, ‘Fast food' and ‘Snacks' were major contributors to the total energy intake for both areas. The mean contribution of ‘Fast food' to total energy intake was significantly higher in the urban area. The prevalence of obesity among Croatian children is high and unrelated to the urban/rural setting, which could be partially explained by the high intake of ‘Fast food' and ‘Snacks'.
