    ·AIM: To describe the clinical characteristics of Turkish patients with intermediate uveitis(IU) and to investigate the effect of clinical findings and complications on final visual acuity(VA).·METHODS: We retrospectively analyzed the medical records of patients with IU who had at least 6mo of follow-up and were older than 16 y.· RESULTS: A total of 78 eyes of 45 patients were included in the study and the mean follow-up period was19.4mo. The mean age at the time of presentation was42.9s. Systemic disease associations were found in17.7% of cases; sarcoidosis(8.8%) and multiple sclerosis(6.6%) were the most common diseases. Recurrence rate(odds ratio=45.53; 95%CI: 2.181-950.58), vitritis equals to or more than 3+ cells(odds ratio =57.456; 95%CI: 4.154-794.79) and presenting with VA less than 20/40(odds ratio =43.81; 95% CI: 2.184-878.71) were also found as high risk factors for poor final VA. At the last follow-up examination, 67.9% of eyes had VA of 20/40 or better.·CONCLUSION: IU is frequently seen at the beginning of the fourth decade of life. The disease is most commonly idiopathic in adult Turkish patients. Patients with severe vitritis at presentation and patients with frequent recurrences are at high risk for poor visual outcome.

    Full Text Available One of the most important components of orthodontic diagnosis and treatment planning is the evaluation of the patient’s soft tissue profile. The main purpose of this study was to develop soft-tissue cephalometric standards for Turkish men and women and compare them with the cephalometric standards of normal European-American white people. The sample included 96 Turkish adults (48 women, 48 men, aged 20 to 27 years. Turkish subjects have increased facial convexity associated with retruded mandible, more obtuse lower face-throat angle, increased nasolabial angle and upper lip protrusion, deeper mentolabial sulcus, and smaller interlabial gap compared with European-American white people. It is appropriate to consider these differences during routine diagnosis and treatment planning of a Turkish patient or an American patient of European ancestry. Turkish males reveal more obtuse mandibular prognathism and upper lip protrusion, and smaller nasolabial angle than females.

    Surface anatomy and anatomical planes are widely used in education and clinical practice. The planes are largely derived from cadaveric studies and their projections on the skin show discrepancies between and within anatomical reference textbooks. In this study, we reassessed the accuracy of common thoracic and abdominopelvic anatomical planes using computed tomography (CT) imaging in the live adult Turkish population. After patients with distorting pathologies had been excluded, CT images of 150 supine patients at the end tidal inspiration were analyzed. Sternal angle, transpyloric, subcostal, supracristal and pubic crest planes and their relationships to anatomical structures were established by dual consensus. The tracheal bifurcation, azygos vein/superior vena cava (SVC) junction and pulmonary bifurcation were usually below the sternal angle while the concavity of the aortic arch was generally within the plane. The tip of the tenth rib, the superior mesenteric artery and the portal vein were usually within the transpyloric plane while the renal hila and the fundus of the gallbladder were below it. The inferior mesenteric artery was below the subcostal plane and the aortic bifurcation was below the supracristal plane in most adults. Projectional surface anatomy is fundamental to medical education and clinical practice. Modern cross-sectional imaging techniques allow large groups of live patients to be examined. Classic textbook information regarding anatomy needs to be reviewed and updated using the data gathered from these recent studies, taking ethnic differences into consideration.

    Neurogenesis in the dentate gyrus of the adult mammalian hippocampus has been proven in a series of studies, but the differentiation process toward newborn neurons is still unclear. In addition to the immunohistochemical study, electrophysiological membrane recordings of precursor cells could provide an alternative view to address this differentiation process. In this study, we performed green fluorescent protein (GFP)-guided selective recordings of nestin-positive progenitor cells in adult dentate gyrus by means of nestin-promoter GFP transgenic mice, because nestin is a typical marker for precursor cells in the adult dentate gyrus. The patch-clamp recordings clearly demonstrated the presence of two distinct subpopulations (type I and type II) of nestin-positive cells. Type I cells had a lower input resistance value of 77.1 M(Omega) (geometric mean), and their radial processes were stained with anti-glial fibrillary acidic protein antibody. On the other hand, type II nestin-positive cells had a higher input resistance value of 2110 MOmega and expressed voltage-dependent sodium current. In most cases, type II cells were stained with anti-polysialylated neural cell adhesion molecule. Taken together with a bromodeoxyuridine pulse-chase analysis, our results may reflect a rapid and dynamic cell conversion of nestin-positive progenitor, from type I to type II, at an early stage of adult neurogenesis in the dentate gyrus.

    This study investigated the relationship between acculturation and psychological problems in Turkish and Moroccan young adults living in the Netherlands. A sample of 131 healthy young adults aged between 18 and 24 years old, with a Turkish or Moroccan background was recruited using snowball sampling. Data on acculturation, internalizing and externalizing problems, beliefs about psychological problems, attributions of psychological problems and barriers to care were collected and analyzed using Latent Class Analysis and multinomial logistic regression. Three acculturation classes were identified in moderately to highly educated, healthy Turkish or Moroccan young adults: integration, separation and diffusion. None of the participants in the sample were marginalized or assimilated. Young adults reporting diffuse acculturation reported more internalizing and externalizing problems than those who were integrated or separated. Separated young adults reported experiencing more practical barriers to care than integrated young adults. Further research with a larger sample, including young adult migrants using mental health services, is required to improve our understanding of acculturation, psychological problems and barriers to care in this population. Including experiences of discrimination in the model might improve our understanding of the relationship between different forms of acculturation and psychological problems.

    Full Text Available There has been much discussion on the involvement of Universal Grammar (UG in Second Language Acquisition (SLA process. Despite growing research in the field, few precise answers to the problem have been suggested so far. Hence, recent L2 studies within the generative framework have shifted from investigating this issue to determining whether or not interlanguage grammars exhibit natural language characteristics (Can, Kilimci & Altunkol, 2007. The present study aimed to investigate L2 acquisition of syntactic movement in English noun clauses by Turkish adult learners. Accordingly, L1 involvement in SLA was sought through examining the upper intermediate Turkish learners’ knowledge about the movement in question. The study addressed the questions of whether or not Turkish adult ESL learners have problems, stemming from L1 interference, with the construction of the syntactic movement in English noun clauses, and whether or not there is any order of acquisition between the noun clauses in subject position and object position along with various wh-words. The study reported related findings, and concluded with a few pedagogical implications for practice, and a couple of suggestions for further directions.

    Full Text Available Abstract Background As little is known about the determinants of smoking in large ethnic minorities in the Netherlands and other Western European countries, we studied the determinants of smoking young adult offspring of Turkish migrants to the Netherlands. Methods Cross-sectional survey of 439 Turkish adults (18–28 y in 2003. Smokers were compared with never smokers for five groups of determinants: demographic and socioeconomic factors, behavioral and emotional problems, psychosocial factors, and cultural factors. Associations were measured by prevalence rate ratios. Results Prevalences for men were 51% for daily smoking, 12% for former smoking, and 38% for never smoking. For women they were 44%, 11%, and 47%, respectively. Without adjustment for other determinants, higher prevalence was associated with: emotional problems, boredom, life events, and being male; and, specifically among women, with low self-esteem and having children. The strongest determinants of daily smoking In multivariate models were alcohol use and demographic and socio-economic factors. Of the cultural factors only strong Muslim identification was associated with lower smoking prevalence. Conclusion The high prevalence of smoking warrants action. Many of the well-known determinants of smoking in Western countries were also important among young adults from ethnic minorities. Women with children and people of a low educational level deserve special attention.

    In this study, we aimed to develop dental charts for Turkish children and young adults of both genders within the age group of 4.5-22.5 years according to tooth mineralization and eruption in a format similar to that proposed by AlQahtani et al. In total, 753 digital panoramic radiographs from 350 males and 403 females were assessed. The permanent teeth were evaluated according to the classification system described by Demirjian et al. The eruption stage was assessed with Bengston's system, which was modified by AlQahtani et al at four points. Teeth generally developed earlier in females than in males. This was particularly notable in the age group of 5-14 years. However, this difference was usually visible in only one stage, not in all teeth. It has been determined that the mixed dentition period ended with the shedding of the second deciduous molars in both genders. The dental charts presented here included information that could be beneficial to dental clinicians in making appropriate diagnosis and planning orthodontic and surgical procedures. These charts also provided datasets for preliminary dental age estimation in Turkish children and young adults.

    Full Text Available Introduction. It is important to know the size of the thyroid gland, and its normal value may vary among different geographic regions. Objective. In this study, we aimed to establish reference ranges for thyroid volume in euthyroid adults and to compare these results with the literature data. Methods. Between June 2011 and June 2012, 461 patients with normal laboratory results (serum TSH, anti-TG, anti-TPO antibodies and urine iodine level that underwent thyroid gland ultrasound examination were retrospectively analyzed. Two hundred and 92 patients were females and 169 were males; the age range was 18-61 years with mean age 30.84±9.97 years. Length, breadth and thickness were measured, and the volume of each lobe was estimated using the ellipsoid formula. Results. The overall mean thyroid volume in all patients who were examined was 12.98±2.53 mL. The mean thyroid volume in females and males was 12.09±2.05 mL and 14.53±2.55, respectively (p<0.05. The right thyroid lobe volume was greater than the left in all patients of both sexes. In addition, the study establishes a significant correlation between the thyroid volume and height, weight and body surface area of the subjects of both sexes (p<0.05. In the light of our findings we can provide reference values in order to evaluate patients who have thyroid hyperplasia or who are considered as normal. Conclusion. We consider that further studies are necessary to establish national references thyroid volume for each country.

    The achievement of sustainability and health objectives in Western countries requires a transition to a less meat-based diet. This article investigates whether the alleged link between meat consumption and particular framings of masculinity, which emphasize that 'real men' eat meat, may stand in the way of achieving these objectives. From a theoretical perspective, it was assumed that the meat-masculinity link is not invariant but dependent on the cultural context, including ethnicity. In order to examine the link in different contexts, we analyzed whether meat-related gender differences varied across ethnic groups, using samples of young second generation Chinese Dutch, Turkish Dutch and native Dutch adults (aged 18-35) in the Netherlands. The Turkish group was the most traditional; it showed the largest gender differences and the strongest meat-masculinity link. In contrast, the native group showed the smallest gender differences and the weakest meat-masculinity link. The findings suggest that the combination of traditional framings of masculinity and the Western type of food environment where meat is abundant and cheap is bound to seriously hamper a transition to a less meat-based diet. In contrast, less traditional framings of masculinity seem to contribute to more healthy food preferences with respect to meat. It was concluded that cultural factors related to gender and ethnic diversity can play harmful and beneficial roles for achieving sustainability and health objectives.

  16. Semantic Categories in the Domain of Motion Verbs by Adult Speakers of Danish, German, and Turkish

    2013-12-01

    Full Text Available Languages differ in the ways they divide the world. This study applies cluster analysis to understand how and why languages differ in the way they express motion events. It further lays out what the parameters of the structure of the semantic space of motion are, based on data collected from participants who were adult speakers of Danish, German, and Turkish. The participants described 37 video clips depicting a large variety of motion events. The results of the study show that the segmentation of the semantic space displays a great deal of variation across all three groups. Turkish differs from German and Danish with respect to the features used to segment the semantic space – namely by using vector orientation. German and Danish differ greatly with respect to (a how fine-grained the distinctions made are, and (b how motion verbs with a common Germanic root are distributed across the semantic space. Consequently, this study illustrates that the parameters applied for categorization by speakers are, to some degree, related to typological membership, in relation to Talmy's typological framework for the expression of motion events. Finally, the study shows that the features applied for categorization differ across languages and that typological membership is not necessarily a predictor of elaboration of the motion verb lexicon.

  17. Expression of the cannabinoid receptor CB1 in distinct neuronal subpopulations in the adult mouse forebrain.

    Cannabinoids can modulate motor behaviour, learning and memory, cognition and pain perception. These effects correlate with the expression of the cannabinoid receptor 1 (CB1) and with the presence of endogenous cannabinoids in the brain. In trying to obtain further insights into the mechanisms underlying the modulatory effects of cannabinoids, CB1-positive neurons were determined in the murine forebrain at a single cell resolution. We performed a double in situ hybridization study to detect mRNA of CB1 in combination with mRNA of glutamic acid decarboxylase 65k, neuropeptide cholecystokinin (CCK), parvalbumin, calretinin and calbindin D28k, respectively. Our results revealed that CB1-expressing cells can be divided into distinct neuronal subpopulations. There is a clear distinction between neurons containing CB1 mRNA either at high levels or low levels. The majority of high CB1-expressing cells are GABAergic (gamma-aminobutyric acid) neurons belonging mainly to the cholecystokinin-positive and parvalbumin-negative type of interneurons (basket cells) and, to a lower extent, to the calbindin D28k-positive mid-proximal dendritic inhibitory interneurons. Only a fraction of low CB1-expressing cells is GABAergic. In the hippocampus, amygdala and entorhinal cortex area, CB1 mRNA is present at low but significant levels in many non-GABAergic cells that can be considered as projecting principal neurons. Thus, a complex mechanism appears to underlie the modulatory effects of cannabinoids. They might act on principal glutamatergic circuits as well as modulate local GABAergic inhibitory circuits. CB1 is very highly coexpressed with CCK. It is known that cannabinoids and CCK often have opposite effects on behaviour and physiology. Therefore, we suggest that a putative cross-talk between cannabinoids and CCK might exist and will be relevant to better understanding of physiology and pharmacology of the cannabinoid system.

The aim of this study was to provide data about the presentation of adult patients with ADHD and evaluate the treatment strategies of Turkish adult psychiatrists based on their personal clinical experience in different hospital settings.Methods: A cross-sectional online survey to be filled out by Turkish adult psychiatrists was designed and administered in May 2014. The survey focused on the treatment environment, patterns of patient applications and transition, treatment strategies, and medication management for adults with ADHD.Results: Significant differences were observed in the number of adult patients with ADHD in follow up, and a significant positive correlation was found between number of adult patients with ADHD in follow up and the clinician’s opinion about their level of self-competence to treat adult ADHD. A significant portion of adult psychiatrists have not received any information about their adult ADHD patients’ treatment during childhood. The most preferred medical treatment was stimulants and the majority of the participants always preferred psychoeducation in addition to medication treatment. A majority of participants did not define themselves competent enough to treat and follow up adult patients with ADHD.Conclusion: The findings of this study indicate the need to increase the knowledge, skills, and awareness of adult psychiatrists about adult ADHD.

    Full Text Available BACKGROUND: Serum levels of insulin-like growth factor-1 (IGF-1 reflect endogenous growth hormone (GH secretion in healthy subjects. Measurements of IGF-1 are useful for diagnosis and follow-up of patients with acromegaly and the diagnosis of GH deficiency in children. AIMS: To assess age dependency and normal ranges of serum IGF-1 levels in healthy Turkish population. SETTING AND DESIGN: We therefore studied 272 healthy adolescents and adults between 15-75 years of age. None had diabetes or other endocrine disease or had received estrogen therapy. MATERIAL AND METHODS: Height, weight, body mass index (BMI and waist-hip ratio were measured in all subjects. Serum samples were obtained during morning hours and IGF-1 was measured by radioimmunoassay. STATISTICAL ANALYSIS: The age-dependent reference range for serum IGF-1 concentrations was calculated by simple least linear regression analysis: the regression line represents the means with 95 percent confidence intervals. Correlation analysis was also done. RESULTS: Ageing was negatively related to serum levels of IGF-1 (P= 0.0001, r=-0.931 with a mean decrease (youngest vs. oldest. IGF-1 levels increased during adolescence, with the highest mean values during puberty. After puberty, a subsequent decline in serum levels of IGF-1 was apparent. There were also a significant difference according to gender; females had significantly higher levels (357.909+/-219.167 mg/L than males (307.962+/-198.41 mg/L (P=0.012.

    Full Text Available Background/Aims: Due to the lack of specific markers, the isolation of pure mesenchymal stem cells (MSCs from murine bone marrow remains an unsolved problem. The present study explored whether the neural ganglioside GD2 could serve as a single surface marker to uniquely distinguish murine bone marrow MSCs (mBM-MSCs from other marrow elements. Methods: Immunocytochemistry and flow cytometry, in combination with quantitative RT-PCR, were used to identify the expression of GD2 on culture-expanded mBM-MSCs. GD2+ and GD2- fractions from mBM-MSCs cultures were sorted by immunosorting. Flow cytometry was performed to further analyze the biomarkers of GD2-sorted and unsorted cells. Employing CFU-F assay and CCK-8 assay, we examined the clonogenic and proliferative capabilities of GD2-sorted and unsorted cells. Using oil red O and von Kossa staining assay, we also assessed the multi-lineage potential of GD2-sortedand unsorted cells. Results: We found that mBM-MSCs expressed a novel surface marker the neural ganglioside GD2. Importantly, mBM-MSCs were the only cells within bone marrow that expressed this marker. Further studies demonstrated that a homogenous population of MSCs could be obtained from bone marrow cultures in early passages by GD2 immunosorting. Compared to parental cells, GD2+-sorted cells not only possessed much higher clonogenic and proliferative capabilities but also had significantly stronger differentiation potential to adipocytes and osteoblasts. Furthermore, GD2+-sorted cells displayed enhanced expression of ES markers SSEA-1 and Nanog. Conclusion: Our observations provide the first demonstration that GD2 may serve as a maker for identification and purification of mBM-MSCs. Meanwhile, our study indicates that the cells selected by GD2 are a subpopulation of MSCs with features of primitive precursor cells.

    Full Text Available The effects of severe protein malnutrition (4% on myenteric neurons of Wistar rat duodenum, in relation to a standard 22%-protein diet for rodents, were assessed in this study. Segments of the duodenum from 10 rats from each nutritional group were submitted to the elaboration of whole mounts - 5 stained with Giemsa to determine the total population of myenteric neurons and the others stained by a histochemical method to detect nervous cells through the NADPH-diaphorase enzyme activity for studying the subpopulation of nitrergic neurons. The area of 100 neurons per animal, totalizing 2,000 neurons, were randomly measured by using the Image Pro-Plus®software. Malnourished rats presented 34.38% lower body weight and 10.60% duodenum length reduction when compared to the control group. Quantitative analysis demonstrated no significant differences between control and malnourished group by using Giemsa; however, as the organ reduction was not followed by an increase inversely proportional to the density of neurons, the condition imposed suggests the loss of neurons from the total population. Nevertheless, through NADPH-d histochemistry, there was a neuronal density increase for the malnourished group. There was no significant difference between the groups for both techniques with respect to the morphometric analysis of the body cell.Objetivou-se avaliar os efeitos da desnutrição protéica severa (4% sobre os neurônios mientéricos do duodeno de ratos Wistar, comparando-se a uma dieta padrão para roedores de 22% de proteína.

    Radiographic evaluation of mineralization and eruption stages of third molars using dental panoramic radiographies can be an efficient tool for chronological age estimation in both forensic sciences and legal medicine. The third molar tooth is utilized for dental age estimation about the age span of 15-23 years because it represents the only tooth still in development. The aim of this study is to obtain and analyze data regarding third molar development and eruption in Turkish population for dental age estimation. A total of 744 dental panoramic radiographies of 394 female and 350 male subjects aged between 8 and 22 years were examined. Third molar development was determined according to the Nolla classification system, and eruption was assessed relative to the alveolar bone level. Mandibular and maxillary third molars were generally found at similar stages of development on both sides. Nolla stage 6 (completed crown calcification) was reached at around the age of 15 in both maxillary and mandibular third molars in both sexes. Alveolar emergence was at around the age of 16 in males and around age of 17 in females. Although third molars' eruption shows greater variability than development of third molars, data which were obtained from this study about eruption of these teeth can be supportive to development data for age estimation.

    The author strongly suspects that such dynamics in the development of diabetes and CHD exist in Western adults prone to impaired glucose tolerance, and evidence is accumulating regarding general Iranian adults. These issues posing a vast threat on public cardiometabolic health will have to be recognized with the purpose of not delaying implementation of measures for the modification of cardiometabolic risk, especially in women.

    Obesity potentially arising from viral infection is known as 'infectobesity'. The latest reports suggest that adenovirus-36 (Adv36) is related to obesity in adults and children. Our aim was not only to determine the Adv36 seropositivity in both obese and non-obese children and adults, but also to investigate correlations between antibody positivity and serum lipid profiles. Both Adv36 positivity and tumour-necrosis-factor-alpha, leptin and interleukin-6 levels were detected in blood samples collected from 146 children and 130 adults by ELISA. Fasting plasma triglycerides, total cholesterol and low-density lipoprotein levels were also measured. Adv36 positivity was determined to be 27·1% and 6% in obese and non-obese children and 17·5% and 4% in obese and non-obese adults, respectively. There was no difference with regard to total cholesterol, low-density lipoprotein, triglyceride, tumour-necrosis-factor-alpha and interleukin-6 levels (P > 0·05). However, there was a significant difference between groups in terms of leptin levels (P obese children and adults. Our results showed that Adv36 may be an obesity agent for both adults and children, parallel with current literature data. However, the available data on a possible relationship between Adv36 infection and obesity both in children and adults do not completely solve the problem.

    Growing understanding of the role of the tumor microenvironment in angiogenesis has brought monocyte-derived cells into focus. Monocyte subpopulations are an increasingly attractive therapeutic target in many pathologic states, including cancer. Before monocyte-directed therapies can be fully harnessed for clinical use, understanding of monocyte-driven angiogenesis in tissue development and homeostasis, as well as malignancy, is required. Here, we provide an overview of the mechanisms by which monocytic subpopulations contribute to angiogenesis in tissue and tumor development, highlight gaps in our existing knowledge, and discuss opportunities to exploit these cells for clinical benefit.

    Although porcine lymphocytes have been classified into numerous subpopulations in postnatal animals, little is known about the ontogeny of these complex cell subsets. Using double- and triple-colour flow cytometry (FCM), we investigated the surface phenotype of fetal lymphoid cells in the thymus, cord blood, spleen and mesenteric lymph nodes at different stages of gestation. It was found that the major lymphocyte subpopulations started to appear at the beginning of the second third of the gestation period, with B cells being the earliest lymphocyte subpopulation to appear in the periphery. The T-cell receptor (TCR) gamma delta+ cells were the earliest detectable T-cell subset, developing first in the thymus and subsequently arriving in the periphery. Later in ontogeny, however, the number of TCRalpha beta+ lymphocytes rapidly increased, becoming the predominant T cells both in the thymus and in the periphery. Cells with the phenotype of adult natural killer cells were also identified in pig fetuses, though their nature and functional roles remain to be investigated. In addition, CD2 was expressed on most B cells whilst very few CD4+ TCRalpha beta+ cells or CD2+ TCRgamma delta+ cells expressed CD8, suggesting that the expression of CD2 and CD8 may reflect the functional status of the cells in postnatal animals. Taken together, this study has provided a systematic analysis of fetal porcine lymphocyte subpopulations and may provide the base for studies to establish the physiological roles of these lymphocyte subsets.

    This study aimed at investigating the effects of individualistic-collectivistic value orientations on non-fatal suicidal behavior and attitudes in Turkish adolescents and young adults. A questionnaire containing measures of individualism, collectivism (INDCOL), non-fatal suicidal behaviors and suicidal attitudes was used to collect the data. The results showed that both suicidal ideation and attempts were significantly more frequent in participants classified as individualist than those who were classified as collectivist on the basis of INDCOL scale scores. Participants with individualistic tendencies displayed more permissive attitudes toward suicide than those with collectivistic tendencies but collectivists believed to a greater extent than the individualists that people should communicate suicidal problems to others. Participants with collectivistic tendencies showed more accepting and helping reactions to an imagined suicidal friend than those with individualistic tendencies. Suicidal ideation and attempts were more common among adolescents than young adults. The findings suggest that individualistic and collectivistic value orientations and developmental status specific stressors play a role in the distribution of nonfatal suicidal behavior and the nature of suicidal attitudes.

    Fingerprints are considered to be one of the most reliable methods of identification. Identification of an individual plays a vital part of any medico-legal investigations. Dermatoglyphics is a branch of science that studies epidermal ridges and ridge patterns. Epidermal ridges are polygenic characteristics that form intrauterine 10-18 weeks and considered fully developed by the sixth month of fetal growth. Fingerprints are permanent morphological characteristics and criminal detection based on fingerprints is based on the principle that no two people can have identical fingerprints. Sex determination from fingerprints has been examined in different population. In this study we aimed to study fingerprint ridge density in Turkish population sample of Baskent University students. Fingerprints were obtained from 118 women, 88 men a total of 206 students aged between 17 and 28 years old by means of simple inking method. Fingerprints from all right and left hands fingers were collected in three different area of each. The ridges on fingerprints were counted diagonally on squares measuring 5 mm × 5 mm on radial, ulnar and inferior areas. The fingerprint ridge density in radial, ulnar and inferior areas and between sexes was compared statistically Mann Whitney U test and Friedman test. The ridge density was significantly greater in women in every region studied and in all fingers when compared to men. The fingerprint ridge density in the ulnar and radial areas of the fingerprints was significantly greater than the lower area. Fingerprint ridge density can be used by medico-legal examination for sex identification.

    Perfluoroalkyl acids (PFAAs) are globally found in various media, including food and especially fishery products. In the present study, the dietary exposure to 15 perfluoroalkyl acids was assessed for 3 French adult populations, namely high seafood consumers, high freshwater fish consumers, and pregnant women. Purified food extracts were analysed by LC–MS/MS and PFBA, PFPA, PFHxA, PFHpA, PFOA, PFNA, PFDA, PFUnA, PFTrDA, PFTeDA, PFBS, PFHxS, PFHpS, PFOS and PFDS were monitored and quantified according to the isotope dilution principle. Under lower bound (LB) hypothesis (i.e. contamination values < LOD considered as 0), high freshwater fish consumers appear as the most exposed to PFOS (7.5 ng.kg{sup −1} bw.d{sup −1}), PFUnA (1.3 ng.kg{sup −1} bw.d{sup −1}), PFDA (0.4 ng.kg{sup −1} bw.d{sup −1}) and PFHpS (0.03 ng.kg{sup −1} bw.d{sup −1}) while high seafood consumers appear as the most exposed to PFOA (1.2 ng.kg{sup −1} bw.d{sup −1}), PFNA (0.2 ng.kg{sup −1} bw.d{sup −1}) and PFHxS (0.06 ng.kg{sup −1} bw.d{sup −1}). For all considered populations, the major exposure contributors are fish, seafood and water under LB hypothesis, while dairy products, bread and crispbread are the main contributors under upper bound (UB) hypothesis. Besides this food exposure assessment, further studies are needed to assess the more global PFAA exposure, taking into account indoor and outdoor air, dust and cutaneous contact, which could be other important contributors for this particular class of chemicals. - Highlights: • The dietary exposure was estimated for 15 perfluoroalkyl acids. • Despite the overestimation, the FFQ remains useful to evaluate the whole diet. • The high fish consumers are the most dietary exposed population. • Fishery products are the main exposure contributors under LB hypothesis.

    Full Text Available The purpose of this study is to adapt the sensation seeking scale for young adults into Turkish and to investigate if the life satisfaction of university students differ significantly in terms of sensation seeking. In addition, it was investigated whether the life satisfaction levels of university students differ significantly in terms of gender. The data for this research was collected from 570 university students. The original form of BSSS-8 consist of 8 items and 4 factors. The scale was subjected to CFA in order to determine the structural validity of its Turkish version and it was found that this version had a single factor structure. The results of the CFA suggested acceptable levels of fit indices (χ2/df = 4.46, RMSEA = .07, GFI =96, CFI = .94, IFI = .94, NFI = .93, AGFI = .93, and NNFI = .91. The reliability coefficient of the scale was found at a level of .79. Furthermore, corrected item total correlation were found to be in a range between .22 and .59. The results suggest that the single factor structure of the scale produces valid and reliable results. In addition, it was found that the life satisfaction levels of university students differ significantly in terms of sensation seeking level, but life satisfaction levels of university students do not differ significantly in terms of gender. The results showed that the life satisfaction levels of students with lower sensation seeking are higher than of students with higher sensation seeking

    Full Text Available According to official figures 3 million Turkish, which contribute to Germany in some fields such as trading, politics, sports, literature, live in Germany. Therefore, a wide variety of academic studies about Turkish people living in Germany are done and going to be done both in Turkey and Germany. Turkish-German commercial relationship, adaptation of Turkish people to Germany and their economic power are the most researched subjects. However, subjects such as Turkish courses and language usage of Turkish people in Germany were postponement until today. For this reason, it is observed that some third-generation Turkish youth can understand but can not express themselves in Turkish language. In this paper, firstly a short description about the Turkish population in Germany is given and afterwards the importance of Turkish language to permanency of Turkish identity is mentioned. Next, studies about this subject which were done in Turkey and Germany are given.

    Because of previously reported associations among the total leukocyte count, cigarette smoking, and risk of cardiovascular disease, we examined the relation of cigarette smoking to various leukocyte subpopulations among 3467 men aged 31 to 45 years. The median total leukocyte count was 36% higher (7840 vs. 5760 cells/mL) among current cigarette smokers than among men who had never smoked, and both stratification and regression analyses were used to examine independent associations with leukocyte subpopulations. At equivalent counts of other subpopulations, CD4+ lymphocytes and neutrophils were the cell types most strongly associated with cigarette smoking; each standard deviation change in counts of these subpopulations increased the odds of current (vs. never) smoking by approximately threefold. Furthermore, whereas 15% of the 238 men with relatively low (men with relatively high counts of both subpopulations were current smokers. Counts of T lymphocytes also tended to be higher among the 32 men with self-reported ischemic heart disease than among other men. These results, along with previous reports of immunologically active T lymphocytes in atherosclerotic plaques, suggest that this subpopulation may be of particular interest in studies examining the relation of leukocytes to cardiovascular disease.

    The first generation of Turkish and Northwest African immigrants in Belgium are ageing and at risk for developing cancer. Relatives play an important role and provide both emotional and practical care, including mental support and acting as a contact person and/or a translator for improving access to healthcare, as most patients and their spouses have only a limited command of the language. Although access to professional interpreters has shown to be the best guarantee for qualitative healthcare, oncology health providers working with relatives as interpreters is much more common than professional interpreters. The aim of this study was to provide insight into the process wherein relatives balance truth-telling in translating for an older family member diagnosed with cancer. This was a qualitative research study, with elements of constructivist grounded theory. Twenty-eight loosely structured interviews were conducted. Most relatives consider it their responsibility to contribute to a positive attitude of the patient. Relatives decided to what extent they inform the patient, based on several motives and embedded in their assessment of the patient's emotional strength, understanding and need to be informed. What they decide influences the way they act as a translator and/or a contact person between the patient and health professional(s). Some considered it best to omit medical information while others considered it best to inform the patient fully. The results emphasise the importance for healthcare providers to take into account the complexity and unpredictable character of the process of balancing truth-telling when family members translate for their ill older relative.

    Hereditary neuropathy with liability to pressure palsies (HNPP) is an autosomal dominant nerve disease usually caused by 1,5 Mb deletion on chromosome 17p11.2.2-p12, the region where the PMP-22 gene is located. The patients with HNPP usually have relapsing and remitting entrapment neuropathies due to compression. We present a 14-year-old male who had acute onset, right-sided ulnar nerve entrapment at the elbow. He had electrophysiological findings of bilateral ulnar nerve entrapments (more severe at the right side) at the elbow and bilateral median nerve entrapment at the wrist. Genetic tests of the patient demonstrated deletions in the 17p11.2 region. The patient underwent decompressive surgery for ulnar nerve entrapment at the elbow and completely recovered two months after the event. Although HNPP is extremely rare, it should be taken into consideration in young adults with entrapment neuropathies.

    The main factors which determined the 1989 migration of Turks in Bulgaria back to Turkey are discussed. Background history is provided. After World War I, Turks in bulgaria comprised 10% of the total population. Bulgarian policy had been, up to the 1980s to send Rumelian Turks back, but the policy after 1980 was one of a national revival process to integrate Turks into the developed socialist society. Muslim traditions, customs, and Turkish language were interfered with. International disfavor resulted. In May 1989, the Communist Party declared, in an effort to show democratic ideals, open borders. Thus began the new emigration wave. 369,839 people fled to the Turkish border. 43% of the 9.47 ethnic Turks in bulgaria went to Turkey within 4 months. The numbers decreased in November, and soon after the communist regime ended. New laws were adopted allowing Turks to assume their original Turkish names. The huge migration was clearly political, and as such, the emigrant Turks should be determined as refugees and asylum seekers. The provocation of ethnic Turks was used by the communist regime to solve potential social conflicts. Not only did Turks flee to escape from violence or for religious, cultural, and moral reasons but also due to free market initiatives begun in Turkey in the early 1980s which improved Turkish quality of life. Food and consumer goods were cheaper and economic advantages were perceived. Emigrants were primarily peasants with lower levels of education, professional qualifications, and labor skills. 154,937 (42%) returned to bulgaria and 58% stayed in Turkey to comprise 25% of the former Turkish population. During this period, tensions between countries was high.l Bulgarians actively encouraged emigration and Turkey welcomed it. The emigrants to Turkey were seen as foreigners (muhacir or gocmen) but were received with good will and were readily accepted into menial positions. Emigrants were confronted with political, linguistic, and cultural

    Full Text Available The aim of this article is to investigate the impact of new Turkish commercial code and Turkish accounting standards on accounting education. This study takes advantage of the survey method for gathering information and running the research analysis. For this purpose, questionnaire forms are distributed to university students personally and via the internet.This paper includes significant research questions such as “Are accounting academicians informed and knowledgeable on new Turkish commercial code and Turkish accounting standards?”, “Do accounting academicians integrate new Turkish commercial code and Turkish accounting standards to their lectures?”, “How does modern accounting education methodology and technology coincides with the teaching of new Turkish commercial code and Turkish accounting standards?”, “Do universities offer mandatory and elective courses which cover the new Turkish commercial code and Turkish accounting standards?” and “If such courses are offered, what are their names, percentage in the curriculum and degree of coverage?”Research contributes to the literature in several ways. Firstly, new Turkish commercial code and Turkish accounting standards are current significant topics for the accounting profession. Furthermore, the accounting education provides a basis for the implementations in public and private sector. Besides, one of the intentions of new Turkish commercial code and Turkish accounting standards is to foster transparency. That is definitely a critical concept also in terms of mergers, acquisitions and investments. Stakeholders of today’s business world such as investors, shareholders, entrepreneurs, auditors and government are in need of more standardized global accounting principles Thus, revision and redesigning of accounting educations plays an important role. Emphasized points also clearly prove the necessity and functionality of this research.

    2016-01-01

    Full Text Available Research on mesenchymal stem cells (MSCs continues to progress rapidly. Nevertheless, the field faces several challenges, such as inherent cell heterogeneity and the absence of unique MSCs markers. Due to MSCs’ ability to differentiate into multiple tissues, these cells represent a promising tool for new cell-based therapies. However, for tissue engineering applications, it is critical to start with a well-defined cell population. Additionally, evidence that MSCs subpopulations may also feature distinct characteristics and regeneration potential has arisen. In this report, we present an overview of the identification of MSCs based on the expression of several surface markers and their current tissue sources. We review the use of MSCs subpopulations in recent years and the main methodologies that have addressed their isolation, and we emphasize the most-used surface markers for selection, isolation, and characterization. Next, we discuss the osteogenic and chondrogenic differentiation from MSCs subpopulations. We conclude that MSCs subpopulation selection is not a minor concern because each subpopulation has particular potential for promoting the differentiation into osteoblasts and chondrocytes. The accurate selection of the subpopulation advances possibilities suitable for preclinical and clinical studies and determines the safest and most efficacious regeneration process.

    Recent innovations in physical activity (PA) assessment have made it possible to assess the walking behaviors of a wide variety of populations. Objective measurement methods (e.g., pedometers, accelerometers) have been widely used to assess walking and other prevalent types of PA. Questionnaires suitable for international populations (e.g., the International Physical Activity Questionnaire and the Global Physical Activity Questionnaire) and measurement techniques for the assessment of gait patterns in disabled populations allow for the study of walking and its health benefits among many populations. Results of studies using the aforementioned techniques indicate that children are more active than adolescents and adolescents are more active than adults. Males, particularly young males, are typically more active than females. The benefits associated with regular participation in PA for youth and walking for older adults have been well documented, although improvements in the assessments of physical, cognitive, and psychosocial parameters must be made if we are to fully understand the benefits of walking for people of all ages. Most youth meet appropriate age-related PA activity recommendations, but adults, particularly older adults and adults with disabilities, are less likely to meet PA levels necessary for the accrual of health benefits. International studies indicate variation in walking by culture. It is clear, however, that walking is a prevalent form of PA across countries and a movement form that has great potential in global PA promotion. Continued development of measurement techniques that allow for the study of individualized gait patterns will help us add to the already rich body of knowledge on chronically disabled populations and allow for individual prescriptions for these populations.

    2015-01-01

    This study presents pioneering data on how adult early bilinguals (heritage speakers) and late bilingual speakers of Turkish and German process grammatical evidentiality in a visual world setting in comparison to monolingual speakers of Turkish. Turkish marks evidentiality, the linguistic reference to information source, through inflectional affixes signaling either direct (-DI) or indirect (-mIş) evidentiality. We conducted an eye-tracking-during-listening experiment where participants were given access to visual ‘evidence’ supporting the use of either a direct or indirect evidential form. The behavioral results indicate that the monolingual Turkish speakers comprehended direct and indirect evidential scenarios equally well. In contrast, both late and early bilinguals were less accurate and slower to respond to direct than to indirect evidentials. The behavioral results were also reflected in the proportions of looks data. That is, both late and early bilinguals fixated less frequently on the target picture in the direct than in the indirect evidential condition while the monolinguals showed no difference between these conditions. Taken together, our results indicate reduced sensitivity to the semantic and pragmatic function of direct evidential forms in both late and early bilingual speakers, suggesting a simplification of the Turkish evidentiality system in Turkish heritage grammars. We discuss our findings with regard to theories of incomplete acquisition and first language attrition. PMID:26441762

    Phagocytosis of granulocytes and monocytes presents a major mechanism that contributes to the clearance of pathogens and cell debris. We analyzed the phagocytic activity of the peripheral blood cell monocytes, three monocyte subpopulations and granulocytes before and up to one year after hematopoietic stem cell transplantation, as well as during transplant-related adverse events. 25 pediatric patients and young adults (median age of 11.0 years) with hemato-oncological malignancies and non malignancies were enrolled in the prospective study. Ingestion of fluorescence-labeled Escherichia coli bacteria was used to assess the phagocytic activity of monocytes and their subpopulations and granulocytes by means of flow cytometry in the patient group as well as in a control group (n=36). During sepsis, a significant increase of phagocytic activity of monocytes (P=0.0003) and a significant decrease of the phagocytic activity of granulocytes (P=0.0003) and the CD14+ CD16++ monocyte subpopulation (P=0.0020) occurred. At the onset of a veno-occlusive disease, a significant increase of phagocytic activity in the CD14++ CD16+ monocyte subpopulation (P=0.001) and a significant decrease in the phagocytic activity of the CD14++ CD16- monocyte subpopulation (P=0.0048) were observed. In conclusion, the phagocytic activity of monocytes, their subpopulations and granulocytes might be a useful and easy determinable parameter that enables identification of post-transplant complications after hematopoietic stem cell transplantation. The alterations of phagocytic activity contribute to the altered immune response that accompanies adverse events after hematopoietic stem cell transplantation.

  8. HISTORICAL VIEW OF CARDINAL VOWELS IN TURKISH

    Directory of Open Access Journals (Sweden)

    2013-04-01

    Full Text Available Turkish is a rich language in terms of presence of vowels. There are eight vowels that originated from the relationship between palatalité, aperture and labialité in terms of their characteristics in general Turkish. These are /a/, /e/, /ı/, /i/, /o, /ö/, /u/ and /ü/. In general, /a/, /i/ and /u/ are considered as cardinal vowels in Turkish. According to this viewpoint, Turkish has a triple vowel system consisting of /a/, /i/ and /u/ in the periods when Turkish could not be pursued in writing. /e/, /ı/, /o, /ö/ and /ü/ vowels have also originated from these three cardinal vowels. Thus, our study is limited to a/, /i/ and /u/ vowels. Periodical restriction of the study is Historical Turkish Dialects Köktürk, Uighur, Karakhanid, Khorezmian, Kipchak, Chagatai and Old Oghuz Turkic languagesIn this study we are aiming to determine the following;1. Sources of /a/, /i/ and /u/ vowels in the historical Turkish dialects,2. Presence of /a/, /i/ and /u/ vowels in the first syllables and other than first syllables,3. Sound events taking place in the /a/, /i/ and /u/ vowels and their reasons,4. relations of /a/, /i/ and /u/ vowels among themselves and with the consonants,5. whether or not /a/, /i/ and /u/ vowels and sound events taking place in these vowels are determinative within a historical dialect.

    Full Text Available The present study tried to determine Turkish learners’ attitudes, and the Turkish education system’s approach towards learner autonomy with regard to three main points: 1 whether Turkish university students are aware of learner autonomy or not 2 whether Turkish university students have the characteristics of autonomous learners (whether they are autonomous learners or not, and 3 if the Turkish education system is suitable for fostering learner autonomy or not from the viewpoint of the participants. Participants were 50 second grade learners in the English Language Teaching Departments of Hacettepe University (N=10, Mehmet Akif Ersoy University (N=10, and Uludag University (N=30 who had already taken courses about learner autonomy.  The data were collected by means of a questionnaire which had two Likert-scale sections and an open-ended questions section. The first Likert-scale section contained 15 characteristics of autonomous learners each of which was rated by the participants in a scale from strongly disagree to agree, from 1 to 5. In the second Likert-scale section, the participants were asked to rate the Turkish education system’s five basic elements such as school curriculums, course materials, approaches used by the teachers in classrooms, learning activities, and classroom settings. Additionally, learners’ opinions about their awareness and understanding of learner autonomy were gathered by five open ended questions. The results proposed that the participants were aware of learner autonomy, and had the characteristics of autonomous learners. On the other hand, results showed that the Turkish education system was not suitable for autonomous learners and did not foster learner autonomy. The findings suggested that the Turkish education system should be designed again in such a way to support the autonomous learners and to foster learner autonomy in all sections of the education.

  17. The Role of Religion and Acculturation in the Consumer Ethnocentrism of Turkish Immigrants in Germany

    Nurdan Sevim

    2016-03-01

    Full Text Available Researchers have invested much effort in the understanding of acculturation-relevant factors that influence immigrants’ psychological and socio-cultural adaptation. Factors that might have an impact on immigrants’ product consumption decisions have comparatively received scarce attention by acculturation and marketing researchers. Immigrants show different product consumption patterns and therefore constitute big consumer groups that can have an impact on both the economy of immigrants’ culture of origin and the host society. The present study investigated Turkish immigrants’ product consumption ethnocentrism. The sample consisted of 599 youth and adult Turkish in Germany drawn from Cologne, the city with the highest ratio of Turkish people in the country. The study sample represented a very similar demographic make-up of the Turkish people in Cologne. The associations between acculturation strategies, loyalty to religion, and product consumption ethnocentrism were quantitatively analyzed based on a field survey. Research findings indicated that participants in the acculturation mode of separation scored significantly higher for consumer ethnocentrism than those showing other orientations, and those with an assimilation orientation scored the least for consumer ethnocentrism. Among the three religiosity dimensions (behavioral, emotional, cognitive investigated in the present study, analyses controlling for a range of socio-demographic variables revealed a positive relationship between the behavior dimension of religiosity and consumer ethnocentrism.

    2008-07-01

    The way adults express manner and path components of a motion event varies across typologically different languages both in speech and cospeech gestures, showing that language specificity in event encoding influences gesture. The authors tracked when and how this multimodal cross-linguistic variation develops in children learning Turkish and English, 2 typologically distinct languages. They found that children learn to speak in language-specific ways from age 3 onward (i.e., English speakers used 1 clause and Turkish speakers used 2 clauses to express manner and path). In contrast, English- and Turkish-speaking children's gestures looked similar at ages 3 and 5 (i.e., separate gestures for manner and path), differing from each other only at age 9 and in adulthood (i.e., English speakers used 1 gesture, but Turkish speakers used separate gestures for manner and path). The authors argue that this pattern of the development of cospeech gestures reflects a gradual shift to language-specific representations during speaking and shows that looking at speech alone may not be sufficient to understand the full process of language acquisition.

  19. Scientific Items in Cyprus Turkish Tales

    Sevilay Atmaca

    2013-05-01

    Full Text Available Folk literature, which is a production of daily life experiences transferred from mouth to mouth, encompasses many types such as epic, legend, folk poetry, mania, laments, songs, riddles, tales, folk story, anecdote, proverbs, idioms, rhymes, and etc. These products, which represent the oral tradition of the people, transfer numerous information regarding the life experiences, beliefs, and values of their communities to the next generation. Tales are more attractive since they depict extraordinary events and because of these characteristics they are very didactic. These are some reasons why tales have a very significant place in Turkish folk literature. People have documented tales successfully transferring from a nomadic life to a settled one. This study attempts to determine the scientific elements in Cyprus Turkish Tales, as sample in the scope of the Turkish Tales, through content analysis. Researchers in this study will examine the themes in the selected tales such as “Earth and Cosmos”, “Physical Event”, “Matter and Change”, and “Living Organisms and Life”. They will also provide a code-list according to the themes found in the tales. Researchers will do a content analysis in relation to the themes and code-listing activities in “Cyprus Turkish Tales” collected by Mustafa Gökçeoğlu, a well-known Cyprus Turkish folk literature writer. It is seen from the research that living organism and life (f: 25 and matter and change (f: 24 themes have very abundant coded. It is followed with an orderly physical events theme (f: 13 and earth and cosmos theme (f: 6. As a result, it is seen that in samples which are taken from Turkish Cypriot Tales, scientific items are widely used. It is believed that the results of the study will give different perspectives to Turkish Language, literature, science-technology, and classroom teacher providing them with interdisciplinary and rich materials.

    HIV-specific cytotoxic T lymphocytes (CTL) are thought to play a major role in viral control in HIV-infected adults. Changes in the relative proportions of CD8 lymphocyte subpopulations are also thought to be associated with disease progression. Less is known about the relative effectiveness of CTL against different HIV targets, or about the relationship, if any, between CTL activity and CD8 subpopulations. We have measured CTL activity against four HIV gene products (gag, tat, pol and env) and expression of CD45RO, CD45RA, HLA-DR, CD29, S6F1, and CD57 surface markers on CD8 cells from nine HIV-infected and 11 HIV-uninfected children. Of nine HIV-infected children, six showed antigen-specific CTL activity on at least one occasion: 4/6 directed against tat, 6/6 against pol, 1/6 against env, and 1/6 against gag. However, the specificity of the CTL activity varied between children and within individual children with time. Furthermore, two uninfected children showed CTL activity, one to HIV-gag, -pol and -tat, and the other to HIV-pol. All the HIV-infected and two uninfected children had abnormal proportions of CD8 subpopulations in whole blood compared with age-matched controls. There was no correlation between CTL activity and CD8 subsets in whole blood. Five children changed from CTL-positive to CTL-negative (or vice versa) during the study. In these, the occasions when CTL activity was detected coincided with an increase in CD8 cells, an expansion of HLA-DR+ CD8 cells and a loss of CD45RA+ CD8 cells.

  5. Spatial and space-time correlations in systems of subpopulations with stochastic migration.

    Epperson, B K

    1994-10-01

    The great majority of models of the population genetics of subdivided populations have made the simplifying assumption that the gene frequencies in migrant groups are deterministic. The present paper examines models which more closely mimic natural conditions, in which the gene frequencies in migrant groups are subject to stochastic effects. It is shown that some types of stochastic migration can cause dramatic changes in spatial correlations and variance. These changes depend on how the stochastic migration effects in the gene frequency recursion equations are shared among nearby subpopulations during the same generation. Only for cases where the effects are completely unshared are the equilibrium spatial and space-time correlations among adult subpopulations unaffected, but the variance is always inflated. The analyses here use novel methods, by recasting population genetic migration-drift models as space-time autoregressive moving average (STARMA) processes. Recent theorems for STARMA processes are employed for finding the spatial correlations, and for the first time in population genetics theory the complete set of space-time correlations, for systems with general patterns of migration rates and numbers of spatial dimensions. The space-time correlations provide a uniquely detailed description of a system, and thus form a link between observed spatial autocorrelation statistics and the underlying space-time population genetic process. STARMA theoretical processes have direct statistical analogues that can be applied for process identification, parameter estimation, model fitting, and forecasting in real systems.

    1994-01-01

    Automatic text tagging is an important component in higher level analysis of text corpora, and its output can be used in many natural language processing applications. In languages like Turkish or Finnish, with agglutinative morphology, morphological disambiguation is a very crucial process in tagging, as the structures of many lexical forms are morphologically ambiguous. This paper describes a POS tagger for Turkish text based on a full-scale two-level specification of Turkish morphology that is based on a lexicon of about 24,000 root words. This is augmented with a multi-word and idiomatic construct recognizer, and most importantly morphological disambiguator based on local neighborhood constraints, heuristics and limited amount of statistical information. The tagger also has functionality for statistics compilation and fine tuning of the morphological analyzer, such as logging erroneous morphological parses, commonly used roots, etc. Preliminary results indicate that the tagger can tag about 98-99\\% of the...

    2012-12-01

    Full Text Available The aim of this study is to identify the traditional Turkish motifs and its relations among present industrial designs. Traditional Turkish motifs played a very important role in 16th century onwards. The arts of the Ottoman Empire were used because of their symbolic meanings and unique styles. When we examine these motifs we encounter; Tiger Stripe, Three Spot (Çintemani, Rumi, Hatayi, Penç, Cloud, Crescent, Star, Crown, Hyacinth, Tulip and Carnation motifs. Nowadays, Turkish designers have begun to use these traditional Turkish motifs in their designs so as to create differences and awareness in the world design. The examples of these industrial designs, using the Turkish motifs, have survived and have Ottoman heritage and historical value. In this study, the Turkish motifs will be examined along with their focus on contemporary Turkish industrial designs used today.

    This research investigates the relationship between Turkish residential electricity consumption, household total final consumption expenditure and residential electricity prices by applying the structural time series model to annual data over the period from 1960 to 2008. Household total final consumption expenditure, real energy prices and an underlying energy demand trend are found to be important drivers of Turkish residential electricity demand with the estimated short run and the long run total final consumption expenditure elasticities being 0.38 and 1.57, respectively, and the estimated short run and long run price elasticities being -0.09 and -0.38, respectively. Moreover, the estimated underlying energy demand trend, (which, as far as is known, has not been investigated before for the Turkish residential sector) should be of some benefit to Turkish decision makers in terms of energy planning. It provides information about the impact of past policies, the influence of technical progress, the impacts of changes in consumer behaviour and the effects of changes in economic structure. Furthermore, based on the estimated equation, and different forecast assumptions, it is predicted that Turkish residential electricity demand will be somewhere between 48 and 80 TWh by 2020 compared to 40 TWh in 2008. - Research Highlights: > Estimated short run and long run expenditure elasticities of 0.38 and 1.57, respectively. > Estimated short run and long run price elasticities of -0.09 and -0.38, respectively. > Estimated UEDT has increasing (i.e. energy using) and decreasing (i.e. energy saving) periods. > Predicted Turkish residential electricity demand between 48 and 80 TWh in 2020.

    Full Text Available Turkish steppe culture constituted a typical structure with regard to its creation and development. It emerged from steppe geography. The geography affected social, politic, economical, military and religious structure of the society substantially. The Turkish culture was shaped up under these influences. The agents of the culture appeared as a shepherd generally. Shepherding provided a basic to the animal husbandry. The shepherds headed to search the fertile grass. Shepherding obliged people to became seminomadic. Thus the life continued in a manner of searching new pastures and shuttling between plateau and winter quarters . The horse that is one of the important ingredient of the culture provided mobility and speed to the culture. In social, politic, and military life of society the horse came into prominence. The nomadic houses or the cars contributed to Turks’ life very much. These nomad houses were shelter at the nights and cold days for them. Going from the plateau to winter quarters and from pasture to another pasture was made easy thanks to these. The finding which took out from graves reflects to all features of the culture.The ruins of nomad houses and horses were arised from the graves . These support the informations which was given in the written sources. Among the findings, there were also The animal struggle scenes which reflect art concept of theseminomadism between tomb finds. This art concept named as turkish animal style. It’s tried to determine The scope of the Turkish culture by emphasizing steppe, shepherding, semi-nomadism, horse, nomad house, tomb. It is also emphasized that aforementioned notions can be used for Turkish culture. Thus, cultural dysphemisms in the turkish culture based on that idea.

    Tumors consist of phenotypically heterogeneous subpopulations of cells which are frequently affected by both autocrine and paracrine factors. Applying concepts from neural network theory, we have developed a computer model of chemical communication among hypothetical tumor cells, which simulates some of the complex epigenetic behavior of real tumors. Deletion of subpopulations often destabilized the whole population. The impact of deletion of specific subpopulations was affected by (a) which subpopulation was deleted, and (b) the timing of the deletion during tumor progression.

    Using oligonucleotide hybridisation or restriction endonuclease analysis, we have characterised the molecular defect in 94 patients with thalassaemia major and four with thalassaemia intermedia of Turkish Cypriot descent. We found that four mutations, namely beta+ IVS-1 nt 110, beta zero IVS-1 nt, beta+ IVS-1 nt 6, and beta+ IVS-2 nt 745 were prevalent, accounting for 69.9%, 11.7%, 8.7%, and 5.6% respectively of the beta thalassaemia chromosomes. This information may help in the organisation of a large scale prevention programme based on fetal diagnosis of beta thalassaemia by DNA analysis in the Turkish population. PMID:3236356

  15. Subpopulations Within Juvenile Psoriatic Arthritis: A Review of the Literature

    Matthew L. Stoll

    2006-01-01

    Full Text Available The presentation of juvenile psoriatic arthritis (JPsA has long been recognized to be clinically heterogeneous. As the definition of JPsA expanded to accommodate atypical manifestations of psoriasis in young children, studies began to reflect an increasingly clear biphasic distribution of age of onset, with peaks in the first few years of life and again in early adolescence. These two subpopulations differ in gender ratio, pattern of joint involvement, laboratory findings and potentially response to therapy. Intriguingly, a similar distribution of age of onset has been observed in juvenile rheumatoid arthritis (JRA, and correlates with patterns of HLA association. While a secure classification of subpopulations within JPsA awaits improved pathophysiologic understanding, future research must consider the possibility that different disease mechanisms may be operative in distinct subsets of patients with this disorder.

  16. Learning to use demonstratives in conversation: what do language specific strategies in Turkish reveal?

    Science.gov (United States)

    Küntay, Aylin C; Ozyürek, Asli; Planck, Max

    2006-05-01

    Pragmatic development requires the ability to use linguistic forms, along with non-verbal cues, to focus an interlocutor's attention on a referent during conversation. We investigate the development of this ability by examining how the use of demonstratives is learned in Turkish, where a three-way demonstrative system (bu, su, o) obligatorily encodes both distance contrasts (i.e. proximal and distal) and absence or presence of the addressee's visual attention on the referent. A comparison of the demonstrative use by Turkish children (6 four- and 6 six-year-olds) and 6 adults during conversation shows that adultlike use of attention directing demonstrative, su, is not mastered even at the age of six, while the distance contrasts are learned earlier. This language specific development reveals that designing referential forms in consideration of recipient's attentional status during conversation is a pragmatic feat that takes more than six years to develop.

    Full Text Available The aim of this research was to explore literate and illiterate concepts from illiterate Turkish women’s perspectives. In the light of this aim, we conducted semi-structured interviews with six illiterate Turkish women attending adult literacy course. The findings of the study have been treated in two dimensions: ‘reasons for illiteracy’ and ‘literacy perception’. Inequalities stemming from gender perception were found to be the real reason behind illiteracy. According to illiterate women, illiteracy meant having problems with transportation, health, child education, and family economics and being dependent on others for these; while literacy means experiencing no problems with these or being self-sufficient regarding them.

  8. APPOSITIONS IN GERMAN AND IN TURKISH

    2012-03-01

    Full Text Available Turkish and German grammar books include word parts combined with secondary nouns. We call these, which exemplify the noun, as apposition. Turkish grammar books draw different conclusions from the term Apposition and it shows that it needs to be especially explicated. The apposition can be seen as resumption of same meaningful lexical units considered as a stylistic device providing a context-dependent credibility of expression, coherence, clarity, variation, adequacy and facility. We use many appositions consciously or unconsciously both in speaking and written language. When we compare the frequency of apposition usage with the relative clause, displaying the same function, apposition is surprisingly higher. According to statistical data, in every 100 sentences chosen from any text, there are about 30 appositions. Nevertheless, the apposition receives little attention especially in grammar teaching books, sometimes it even does not. Although it’s rare occurrence in the grammar books, we constantly encounter their syntactic, semantic and pragmatic dimensions in various types of texts. The reason why the Apposition in grammar teaching has received little discussionmight be a topic of other studies and we are not going to deal with this issue here. The purpose of this particular study is to reveal how much the Apposition is known as a grammatical category by our students and what can be done to increase the related awareness in this regard. Within the scope of this research study, the relative clauses present significance, as they are the most preferred and used ones among the Turkish learners who learn German as a foreign language. Due to their morphosyntactic structural difficulties, they are often memorized more than other forms of sentence. Moreover, they require more effort and in spoken form, they are economically impractical. However, it does not mean that theyarenotused or exaggerated in their usage because each mode of expression has

    Purpose : Radiation-induced alteration in the immune function is well known phenomenon in cancer patients. Our purpose is to evaluate the extent of immune suppression immediately after mediastinal or pelvic irradiation, which include significant volume of active bone marrow in adults. Methods and Materials : 48 cancer patients with mediastinal(N=29) and pelvic irradiation(N=19) were the basis of this analysis. Age ranged from 36 to 76 and mean and median value was 57 years, respectively. Sex ratio was 1.3(M:F 27/21). The immunological parameters were the complete blood cell(CBC) with differential cell(D/C) count, T cell subset(CD3, CD4, CD8, CD19), NK cell test(CD16,CD56), and serum immunoglobulin (lgG, lgA, lgM) level. Results : The mean value of white blood cell(WBC) was reduced from 7017 to 4470 after irradiation (p=0.0000). In the differential count, the number of lymphocyte, neutrophil, and basophil was markedly reduced with statistical significance(p<0.01) and the number of monocyte was not changed and, on the contrary, that of eosinophil was increased by irradiation. In the lymphocyte subpopulation analysis, the number of all subpopulations, CD3(T cell), CD4(helper T cell), CD8(suppressor T cell), CD16(NK cell), CD19(B cell) was reduced with statistical significance. The mean ratio of CD4 to CD8 in all patients was 1.09 initially and reduced to 0.99 after radiotherapy(p = 0.34), but the proportional percentage of all subpopulations was not changed except CD19(B cell) after irradiation.In the immunoglobulin study, initial values of lg G, lg A, and lg M were relatively above the normal range and the only lg M was statistically significantly reduced after radiotherapy(p=0.02). Conclusion : Mediastinal and pelvic irradiation resulted in remarkable suppression of lymphocyte count in contrast to the relatively good preservation of other components of white blood cells. But the further study on the functional changes of lymphocyte after radiotherapy may be

    Some methods for determining sperm DNA fragmentation, such as the sperm chromatin structure assay (SCSA) and the sperm chromatin dispersion test (SCD), provide additional information about particular subgroups of spermatozoa with specific irregularities. Thus, SCSA recognizes a specific sperm subpopulation, the high-DNA stainability sperm subpopulation (HDS), and SCD recognizes the so-called DNA-degraded sperm (DDS) subpopulation. Although some studies associate the presence of these subpopulations with specific aspects related to infertility, the relationship between both sperm subpopulations and their preponderance in specific clinical groups of infertile males has not been extensively investigated. In this study, HDS and DDS subpopulations were determined in a total of 37 human males: 8 males with proven fertility, 9 infertile males with asthenoteratozoospermia, 10 carriers of chromosomal reorganizations, and 10 infertile males with clinical varicocele. Results showed a significant increase of the DDS subpopulation (P HDS subpopulation (P = .542), but the highest values were found in the varicocele and rearranged-genome groups. However, no correlation between the HDS and DDS subpopulations were found (r = 0.196; P = .244), suggesting that both represent a different class of sperm subpopulation in the ejaculate. A significant increase in HDS, and especially DDS, can be associated with the presence of varicocele or the rearrangement of chromosomes. Specific diagnostic tests to confirm the diagnosis must be performed in patients with increased DDS and HDS values.

    Life statistics of four Aedes aegypti subpopulations from the subtropical province of Misiones were studied during autumn and winter, under semi-natural conditions, coming from the localities of Posadas (SW), San Javier (SE), Bernardo de Irigoyen (NE) and Puerto Libertad (NW). The eastern subpopulations are geographically separated by the central mountain system of the province from the western subpopulations. High percentages of larval and pupal survival (97-100%) were recorded, and no significant differences were detected among the four subpopulations. Larvae and pupae lasted approximately 8 days to complete their development, no significant differences being detected among the four subpopulations studied. Sex ratio recorded did not differ significantly from 1:1. Male longevity did not show difference among the different subpopulations, but female longevity was remarkably different among the four subpopulations (F=16.27; d.f.=(3;8); P=0.0009), ranging among 11.45 days for San Javier and 57.87 days for Posadas. Fecundity also varied considerably among subpopulations, the greatest number (307.44 eggs/female) being recorded for Posadas (F=4.13; d.f.=(3;8); P=0.04). Ae. aegypti females of the western subpopulations lived longer than the eastern subpopulations studied, therefore, the risk of dengue outbreak would be greater on the Misiones Province border with Paraguay.

    Mechanical allodynia, a cardinal symptom of persistent pain, is associated with the unmasking of usually blocked local circuits within the superficial spinal or medullary dorsal horn (MDH) through which low-threshold mechanical inputs can gain access to the lamina I nociceptive output neurons. Specific interneurons located within inner lamina II (IIi) and expressing the gamma isoform of protein kinase C (PKCγ⁺) have been shown to be key elements for such circuits. However, their morphologic and electrophysiologic features are still unknown. Using whole-cell patch-clamp recordings and immunohistochemical techniques in slices of adult rat MDH, we characterized such lamina IIi PKCγ⁺ interneurons and compared them with neighboring PKCγ⁻ interneurons. Our results reveal that PKCγ⁺ interneurons display very specific activity and response properties. Compared with PKCγ⁻ interneurons, they exhibit a smaller membrane input resistance and rheobase, leading to a lower threshold for action potentials. Consistently, more than half of PKCγ⁺ interneurons respond with tonic firing to step current. They also receive a weaker excitatory synaptic drive. Most PKCγ⁺ interneurons express Ih currents. The neurites of PKCγ⁺ interneurons arborize extensively within lamina IIi, can spread dorsally into lamina IIo, but never reach lamina I. In addition, at least 2 morphologically and functionally different subpopulations of PKCγ⁺ interneurons can be identified: central and radial PKCγ⁺ interneurons. The former exhibit a lower membrane input resistance, rheobase and, thus, action potential threshold, and less PKCγ⁺ immunoreactivity than the latter. These 2 subpopulations might thus differently contribute to the gating of dorsally directed circuits within the MDH underlying mechanical allodynia.

    The adaptations of Bram Stoker’s Dracula (1897) in Turkish literature and film are relatively unknown by Western academia and have been poorly discussed by Turkish critics and scholars on the grounds of being superficial copies of the original. However, they have great importance not only for Turkish Horror studies but also for recently formed Globalgothic studies. In 1928, a novel named Vlad the Impaler was published in Ottoman Turkish by Ali Rıza Seyfi, a historian and a poet from newly fou...

    A group of patients with atopic dermatitis who attended the Allergy Outpatient Service of the Hermanos Ameijeiras Clinical Surgical Hospital from May, 1987 to May, 1988 were studied. The patients were assigned to 2 groups; the first one composed of 38 patients and the second one composed of 12 non-allergic, supposedly healthy subjects. Different tests were carried out for the quantification of total serum immunoglobulins (A, G, M, E) by means of the radial immunodiffusion method and the ELISA ultramicromethod. They were also submitted to quantification of lymphocyte subpopulations by means of the indirect immunofluorescence test with monoclonal antibodies, using Cuban antiserum prepared at the National Institute of Oncology and Radiobiology. In our study IgG and IgA values were within normal limits in patients, contrary to the statistically significant increase in IgM and IgE values. The relative values of total T-lymphocytes (anti-T3) and of the suppressor lymphocyte subpopulations decreased.

    Full Text Available Background: The primary objective was to examine and compare the breast cancer screening adherence rates between black (African American and Afro-Caribbean and Hispanic (foreign born Hispanic and US-born Hispanic subpopulations. Methods: Study data was collected in community settings in New York City between the years of 2011-2012. Participants (N=592 were black and Hispanic individuals who attended a breast cancer screening community outreach program. Breast cancer screening rates as well as demographic data were collected. Results: Results revealed that Afro-Caribbean and foreign-born Hispanics are at a greater risk for non-adherence in breast cancer screening compared with African Americans and US-born Hispanics. Conclusions: The majority of breast screening research and community outreach programs categorize people into broad racial and ethnic groups (e.g., black and Hispanic. The results revealed significant variability within these broader racial/ethnic categories with regard to breast cancer screening. Community outreach programs and future research efforts should target the subpopulations that are at particular risk for breast cancer screening non-adherence.

    [Purpose] This study describes the cultural adaptation, validation, and reliability of the Turkish version of the Pain Catastrophizing Scale in patients with ankylosing spondylitis. [Methods] The validity of the Turkish version of the Pain Catastrophizing Scale was assessed by evaluating data quality (missing data and floor and ceiling effects), principal components analysis, internal consistency (Cronbach's alpha), and construct validity (Spearman's rho). Reproducibility analyses included standard measurement error, minimum detectable change, limits of agreement, and intraclass correlation coefficients. [Results] Sixty-four adult patients with ankylosing spondylitis with a mean age of 42.2 years completed the study. Factor analysis revealed that all questionnaire items could be grouped into two factors. Excellent internal consistency was found, with a Chronbach's alpha value of 0.95. Reliability analyses showed an intraclass correlation coefficient (95% confidence interval) of 0.96 for the total score. There was a low correlation coefficient between the Turkish version of the Pain Catastrophizing Scale and body mass index, pain levels at rest and during activity, health-related quality of life, and fear and avoidance behaviors. [Conclusion] The results of this study indicate that the Turkish version of the Pain Catastrophizing Scale is a valid and reliable clinical and research tool for patients with ankylosing spondylitis.

Method: The participants of the present research consisted of 159 (52.5% female and 144 (47.5% male; a total of 303 Turkish young adults. Average age of the participants was 20 years and 11 months. The ERQ, the Emotional Self- Efficacy Scale, the Regulatory Emotional Self-efficacy Scale, the Satisfaction of Life Scale, and Oxford Happiness Scale (Short form were used as data collection tools. Confirmatory factor analysis (CFA were used for investigation of the psychometric properties of the ERQ. Also, criterion-related validity, test-retest validity, and internal consistency were used calculated. Results: The CFA results showed that standardized item estimates of the ERQ ranged between 0.47 and 0.74. Also the CFA results showed that the original factor structure of the ERQ confirmed on the Turkish sample. Besides, item-total correlations were above the 0.33. The independent samples t-test results indicated that there were significant difference between the total scores of upper 27% and lower 27% groups for all items. Internal consistency coefficients of the scale were determined as 0.78 for cognitive reappraisal and 0.71 for suppression. Test-retest results of the subscales were above 0.65. Conclusion: The findings showed that factor structures of the ERQ’s reappraisal and suppression had psychometric quality in Turkish version. Consequently, the scale could be used in individual or group focused psychotherapy and research.

    Full Text Available Contemporary cinematography reflects the dualism in modern Turkish society. The heart of every inhabitant of Anatolia is dominated by homesickness for his little homeland. This overpowering feeling affects common people migrating in search of work as well as intellectuals for whom Istanbul is a place for their artistic development but not the place of origin. The city and “the rest” have been considered in opposition to each other. The struggle between “the provincial” and “the urban” has even created its own film genre in Turkish cinematography described as “homeland movies”. They paint the portrait of a Turkish middle class intellectual on the horns of a dilemma, the search for a modern identity and a place to belong in a modern world where values are constantly shifting.

    Full Text Available At the end of the First World War, the Ottoman Empire collapsed and the Great Powers came to take the control of its territories. Having a strategic position at the southern gate of Europe, all of Turkish lands were very important for the First World War winners, both to secure European borders and to develop the trade between Europe and Middle East. On the other side, under Mustafa Kemal Atatürk command, a new Turkey with a strong nationalist way decided to fight for emancipating. Winning the war with the Great Powers not only in a military way, but also from a diplomatic perspective, the new Turkey became a modern regional power, having institutions and laws that assured its prosperity and security. Taking into consideration the independence war evolution, this paper wants also to show the diplomatic capability of Turkish leaders to balance between powers involved in the region.

    A Total Diet Study (TDS) consists of selecting, collecting and analysing commonly consumed foods to obtain concentration data of different chemical compounds in foods as eaten. A TDS food list summarises the most consumed foods and represents the dietary habits of the general population of the country under study. The work reported here investigated whether TDS food lists that were initially designed for the whole population of the country under study also sufficiently cover the dietary pattern of specific subpopulations that are extra vulnerable for certain contaminants. The work was performed using data of three European countries: the Czech Republic, France and the UK. Each national food consumption database was combined with the corresponding national TDS food list (containing 336, 212 and 119 food items for the Czech Republic, France and the UK, respectively). The data were aggregated on the highest level of hierarchy of FoodEx-1, a pan-European food classification system, including 20 main FoodEx-1 groups. For the group 'milk and dairy products', the coverage of the consumption by the food list was investigated for more refined subgroups. For each food group or subgroup and country, the average percentage of coverage of the diet by the national TDS food list was calculated for different subpopulations, including children versus adults, women versus men, vegetarians versus non-vegetarians, and women of child-bearing age versus older women. The average diet of the different subpopulations was sufficiently covered by the food list of the Czech Republic and France. For the UK the average coverage was low due to a different food-coding approach and because food lists were not derived directly from national food consumption data. At the level of the 20 main food groups, differences between the subpopulations with respect to the average coverage of consumption by the TDS food list were minimal. The differences were more pronounced when looking in detail at the

    Full Text Available Joint focus of attention is one of the most crucial elements in effective communication. Demonstrative pronouns (DPs have an important role in providing this joint focus of attention. Although demonstratives are a prevalent topic, not many studies are conducted to find out the developmental stages of them. Therefore, the current study attempts to find out children’s comprehension of DPs in Turkish. Based on the results of the study, children’s developmental stages in different age groups are provided. Turkish has a three-way distinction in its demonstrative pronoun system: bu (this, şu (this/that and o (that. The subjects of the study were 12 children of ages 3,4 and 5. The results of the study were intriguing and they showed that learning the demonstrative system in Turkish might follow U-shaped learning pattern. Also, the results seem to support egocentrism hypothesis that children under the age of six had difficulty in shifting the deictic center when they and the experimenter have a different perspective. The use of şu at the age of 4 also showed surprising results.

    Full Text Available Listening skill has an important place in people’s life, but is often neglected. This skill is obtained before birth, and should be developed systematically at school. People with developed listening skill are successful at education and in their social lives. To achieve this skill teachers are very important. First of all teachers should have enough knowledge about listening and listening problems. Especially Turkish teachers should try to improve listening skill. The aim of this study is to show the problems of Turkish teachers about listening and develop opinions and approaches to solve these problems. For this reason 97 Turkish-teacher candidates of Çukurova University were questioned in 2012-2013 academic year and these opinions were investigated according to gender factor. The question “What are the problems you face when listening to someone?” was asked, and so answered according to willingness. Data obtained from participants were investigated with content analyze technique, and classified into categories, sub-categories and themes. Participants indicated that listening problems happen % 58 because of senders, and % 22 because of receivers and % 21 because of other problems. It was observed that there is no great different on the base of gender. Some evaluations were made about listening problems and some suggestions were made.

    The purple-colored unique gem material is only found in the Harmanc Latin-Small-Letter-Dotless-I k (Bursa) region of the western Anatolia (Turkey). Therefore, it is specially called 'Turkish purple jade or turkiyenite' on the worldwide gem market. Even though its jadeite implication is the principal constituent, the material cannot be considered as a single jadeite mineral since other implications are quartz, orthoclase, epidote, chloritoid and phlogopite minerals. Even if the analytical methods are used to characterize and identify the Turkish purple jade samples in detail, the luminescence spectra, especially photoluminescence features regarding to composite mineral implications of the material are important because of the existence the numerous characteristic broad and intensive luminescence bands in the samples. We can state that the UV-irradiation luminescence centers as photoluminescence (PL) are due to the overall signals in the Turkish purple jade samples. Accordingly, the distinctive photoluminescence peaks at 743, 717, 698, 484, 465 and 442 nm in PL-2D (counter diagram and sections) and PL-3D (sequence spectra) ranging between 300 and 900 nm of wavelengths, and between 220 and 340 K of temperatures are observed. Finally, photoluminescence features of the heterogeneous-structured material cannot be simply attributed to any chemical impurities, since the jade mass has numerous heterogeneous mineral constituents instead of a single jadeite mineral. Six different mineral implications and chemical impurities in the material composition display complex and individual all kind of luminescence features. Therefore, photoluminescence as well as radioluminescence, cathodoluminescence and thermoluminescence spectra provide positive identification regarding to the provenance (geographic origin) of the original Turkish purple jade (turkiyenite). - Highlights: Black-Right-Pointing-Pointer The purple-colored gem material is only found in the Harmanc Latin

    Full Text Available This study aimed to adapt the Emotional Regulation Questionnaire into Turkish and investigate its validity and reliability. The Turkish version of the Emotion Regulation Questionnaire was administered to 442 university students. Firstly, language equivalence of the Turkish version the Emotional Regulation Questionnaire was investigated and findings indicated that the Turkish translation of the Emotion Regulation Questionnaire is equivalent to the original form. Confirmatory factor analyses successfully revealed the two-factor (reappraisal and suppression structure of the Turkish version the Emotional Regulation Questionnaire. Further, based on the two-factor model, results from multi-group analysis indicated that the Turkish version of the Emotional Regulation Questtionnaire has the property of strict factorial invariance across gender, including equal factor loadings, equal item intercepts, and equal item uniqueness (error variances and covariances. The internal consistencies were .78 for the reappraisal and .73 for the suppression subscales. Test-retest reliabilities were .74 for the reappraisal and .72 for the suppression subscales. Overall, the Turkish version of the Emotional Regulation Questionnaire has adequate psychometric properties and can be used to examine emotion regulation among Turkish university students.

    This paper describes our work on parsing Turkish using the lexical-functional grammar formalism. This work represents the first significant effort for parsing Turkish. Our implementation is based on Tomita's parser developed at Carnegie-Mellon University Center for Machine Translation. The grammar covers a substantial subset of Turkish including simple and complex sentences, and deals with a reasonable amount of word order freeness. The complex agglutinative morphology of Turkish lexical structures is handled using a separate two-level morphological analyzer. After a discussion of key relevant issues regarding Turkish grammar, we discuss aspects of our system and present results from our implementation. Our initial results suggest that our system can parse about 82\\% of the sentences directly and almost all the remaining with very minor pre-editing.

    Evolution of antibiotic resistance in bacterial populations is an increasing problem having fatal consequences for treatment of diseases. Therefore it is very important to understand this evolution. Traditionally evolution is considered to happen by single point mutations, where each mutant must...... have a growth advantage over the parent strain and grow to a sufficient number before a second mutation can occur. However, when multiple mutations are necessary for development of resistance, single mutations occurring with a normal mutation rate can not always explain the observed resistance. We...... introduce an alternative hypothesis by which a subpopulation of mutators drives the evolution process. Resistance is acquired by a subpoplution of mutators, for which the mutation rate is much higher than the wild-type. If the resistance is located on a transferable plasmid it can subsequently...

    Mesenchymal stem cells (MSC) are capable of differentiating into cells of multiple cell lineages and have potent paracrine effects. Due to their easy preparation and low immunogenicity, MSC have emerged as an extremely promising therapeutic agent in regenerative medicine for diverse diseases. However, MSC are heterogeneous with respect to phenotype and function in current isolation and cultivation regimes, which often lead to incomparable experimental results. In addition, there may be specific stem cell subpopulations with definite differentiation capacity toward certain lineages in addition to stem cells with multi-differentiation potential. Recent studies have identified several subsets of MSC which exhibit distinct features and biological activities, and enhanced therapeutic potentials for certain diseases. In this review, we give an overview of these subsets for their phenotypic, biological and functional properties.

And as the second stage, candidates to teach Turkish to Turkic speakers should be taught with a separate curriculum and under the roof of a different department in order to specialize in the field. 5. Lastly, publications regarding how to teach Turkish to Turkic speakers should not be prepared at a desk, but right on the field, practically, seeing the realities of the region.” (Yılmaz 2015 Furthermore, the fact that “Forming a common communicative language is possible by means of a single language that can communicate between all Turkic communities,” (Ercilasun 1992: 358 (Alioğlu 2013 must never be disregarded. Teaching Turkish as spoken in Turkey should be divided into two main sections as “Teaching Turkish as spoken in Turkey to Native Turkic speakers” and “Teaching Turkish as spoken in Turkey to Non-native Speakers” and teaching methods and educational tools should be determined accordingly. “Teaching Turkish as spoken in Turkey to Native Turkic speakers” should also be classified into groups. For example, under the sub title of “Teaching Turkish as spoken in Turkey to Turkic speakers”, specific course books for “Azerbaijan Turks, Kirghiz Turks, Kazakh Turks, Uzbek Turks and Turkman Turks, etc.” should be prepared in order to teach them Turkish as spoken in Turkey. In addition, instead of grammar based methods, techniques that give grammatical knowledge subtly should be preferred in Teaching Turkish as Spoken in Turkey to Turkic Speakers. While teaching Turkish to adults that come from various parts of the world with various language knowledge and skills, we should benefit from the power of pictures and shapes which are considered the common language of humankind.

    This study was designed to analyze the sperm kinematic and morphometric subpopulations in the different fractions of the ejaculate in normozoospermic men. Ejaculates from eight normozoospermic men were collected by masturbation in three fractions after 3–5 days of sexual abstinence. Analyses of sperm motility by computer-assisted sperm analysis (CASA-Mot), and of sperm morphometry by computer-assisted sperm morphometry analysis (CASA-Morph) using fluorescence were performed. Clustering and discriminant procedures were performed to identify sperm subpopulations in the kinematic and morphometric data obtained. Clustering procedures resulted in the classification of spermatozoa into three kinematic subpopulations (slow with low ALH [35.6% of all motile spermatozoa], with circular trajectories [32.0%], and rapid with high ALH [32.4%]), and three morphometric subpopulations (large-round [33.9% of all spermatozoa], elongated [32.0%], and small [34.10%]). The distribution of kinematic sperm subpopulations was different among ejaculate fractions (P < 0.001), with higher percentages of spermatozoa exhibiting slow movements with low ALH in the second and third portions, and with a more homogeneous distribution of kinematic sperm subpopulations in the first portion. The distribution of morphometric sperm subpopulations was also different among ejaculate fractions (P < 0.001), with more elongated spermatozoa in the first, and of small spermatozoa in the third, portion. It is concluded that important variations in the distribution of kinematic and morphometric sperm subpopulations exist between ejaculate fractions, with possible functional implications.

    The aim of the present study was to determine the perception of 10 anti-smoking advertisements in 1434 Turkish adolescents. We used the Effectiveness of the Anti-smoking Advertisements Scale, which included 6 items for each advertisement; each item was assessed on a 5-point Likert-type scale. Multiple logistic regression analysis was used to determine the factors associated with the impact of the advertisements. All the advertisements were more effective for adolescents who had never smoked compared to ex-smokers and current smokers. We also noted that, regardless of age, smoking status decreased the effectiveness of all the advertisements. Previous studies have shown that smokers have a negative attitude towards anti-smoking messages. In the present study, the most effective advertisements among adolescents were those with "Sponge and tar", "Smoking harms in every breath" and "Children want to grow". In conclusion, although anti-smoking campaigns are targeted towards adults, they also have a strong influence on adolescents. The main target population for advertisements should be individuals aged < 15 years who have not yet started smoking.

    Full Text Available Turkish Classical Music, especially with the success at the Ottoman period, is a music of a civilization. It became a common language in all geographies and people that Turks made contacts with in various ways. Turkish civilization does not deny what she learned from Persians and Arabs, but she managed to use them to improve herself and developing better by adding the information to herself. This shows her power of creating civilization. One of the main signs of this three-continent-spread culture is of course Turkish Classical Music. İt is seen that collective awareness and mind which forms Turkish Classical Music, first recovered the common points, coming from the roots, between Turkish “boy” clans then considered the musical specialities of other societies that share same climate, geography, or some cultural values with Turks. In this manner, the music developed, came to the point that we say “classic”, in which societies and nations found themselves within, by climbing over the identity of being a particular group’s or society’s music. This study is directed towards to recover the main components which gives Turkish Classical Music its character in the process of development by looking beyond the history. In this point the relationship between Turkish Classical and Folk Music is presented.The main path to Muslim Turkishness in the art and political area – Oguz Turkishness is emphasized and their understanding and behaviour before and after Islam is discussed from the music side. Second mainland of Turks, Anatolia is again discussed under another title by the means of Seljuks, Anatolian Seljuks and Beyliks periods; reflections of Oguz “bey” understanding in music is told.

    For the last 500 years, the Americas have been a melting pot both for genetically diverse humans and for the pathogenic and commensal organisms associated with them. One such organism is the stomach-dwelling bacterium Helicobacter pylori, which is highly prevalent in Latin America where it is a major current public health challenge because of its strong association with gastric cancer. By analyzing the genome sequence of H. pylori isolated in North, Central and South America, we found evidence for admixture between H. pylori of European and African origin throughout the Americas, without substantial input from pre-Columbian (hspAmerind) bacteria. In the US, strains of African and European origin have remained genetically distinct, while in Colombia and Nicaragua, bottlenecks and rampant genetic exchange amongst isolates have led to the formation of national gene pools. We found three outer membrane proteins with atypical levels of Asian ancestry in American strains, as well as alleles that were nearly fixed specifically in South American isolates, suggesting a role for the ethnic makeup of hosts in the colonization of incoming strains. Our results show that new H. pylori subpopulations can rapidly arise, spread and adapt during times of demographic flux, and suggest that differences in transmission ecology between high and low prevalence areas may substantially affect the composition of bacterial populations.

  20. Giant neurons in the macaque pulvinar: a distinct relay subpopulation

    Directory of Open Access Journals (Sweden)

    2007-07-01

    Full Text Available Calbindin positive (CB+ giant neurons are known to occur within the pulvinar nucleus in subhuman primates. Here, we demonstrate by combined retrograde tracing and immunocytochemistry that at least some of these are pulvinocortical relay neurons, and further report several distinctive features. First, in contrast with non-giant relay neurons, the giant neurons are often solitary and isolated from a main projection focus. The question thus arises of whether their cortical projections may be non-reciprocal or otherwise distinctive. Second, these neurons are positive for GluR4; but third, they are otherwise neurochemically heterogeneous, in that about one-third are positive for both parvalbumin (PV and CB. Presumably, these subpopulations are also functionally heterogeneous. These results provide further evidence for the idea of multiple, interleaved organizations within the pulvinar; and they imply that thalamocortical projections are more disparate than has yet been appreciated. Finally, we found that giant CB+ neurons have a distinctive meshwork of large, PV+ terminations, prominent at the first dendritic branch point. In size and location, these resemble inhibitory terminations from the zona incerta or anterior pretectal nucleus (APT, as recently described in higher order thalamic nuclei in rats. One can speculate that giant neurons in the macaque pulvinar participate in a layer 5-APT-thalamus (giant neuron extrareticular pathway, functionally distinct from the layer 6-reticular nucleus-thalamus network.

    Growing evidence indicates that the amygdala modulates hippocampal functions. To test the hypothesis that this modulation may involve long-lasting effects on interneuronal networks in the hippocampus, changes in the expression of neurochemical markers specific for different interneuronal subpopulations were assessed in adult rats 96 h following acute infusion of low doses of the GABAA receptor antagonist picrotoxin into the amygdala. The numerical density (Nd) of somata showing immunoreactivity (IR) for parvalbumin (PVB) was decreased in dentate gyrus (DG) and the CA4-2 region, while that of calretinin (CR)-IR was decreased in DG and CA2. The Nd of calbindin D28k (CB)-IR somata was decreased in CA3-2. The densities of axon terminals arising from PVB-IR and cholecystokinin (CCK)-IR basket neurons were also altered, with those of CCK-IR terminals increased across all sectors, while PVB-IR terminals were decreased only in the CA region. Increases in CCK-IR terminals were paralleled by increases of terminals with IR for the 65-kD isoform of glutamate decarboxylase (GAD65). Mixed-effects statistical models, adapted specifically for these analyses, indicated that perturbations of amygdalar inputs to the hippocampus significantly alter the drive that hippocampal PVB-, CR-, and CB-IR neurons within the dentate gyrus/CA4 region exercise on CCK-IR terminals within the same region as well as in CA3-1. These results suggest that amygdalar modulation of specific neuronal subpopulations may induce lasting and far-reaching changes in the hippocampus during normal functioning, as well as in diseases involving a disruption of amygdalar activity. In particular, changes in specific interneuronal markers within selective hippocampal sectors detected in the present results are strikingly similar to those reported in this region in schizophrenia. These similarities suggest that, in this disease, a disruption of GABAergic transmission within the amygdala may play a significant role in

    Full Text Available Profitability of banking sector is the most important instrument of financial system for the future of the economy. The objective of this study is to determine by using Johansen and Juselius cointegration test approach of the bank specific and macroeconomic factors that affect the profitability of commercial banks in Turkish banking sector. In study, the data are collected from the three biggest state-owned, privately-owned and foreign banks. The sample period spans from 1998 to 2011. In the study, return of asset, return of equity and net interest margin were used as proxy for profitability of banks. The bank specific determinants, which were thought to have effects on profitability are total credits/total assets, total deposits/total assets, total liquid assets/total assets, total wage and commission incomes/ total assets, total wage and commission expenses/total assets, the logarithm of total assets and total equity/total assets. The macroeconomic determinants of study are real gross domestic product, inflation rate, real exchange rate and real interest rate. Empirical findings suggest that the bank specific determinants have been more effect than macroeconomic factors on profitability of the banks. The reel gross domestic product and real exchange rate have been effective on the profitability. In addition, the 2001 economic crisis has a negative effect on all Turkish Banking sector.

    Calbindin cells represent a major interneuron subtype of the cortical/pallial regions, such as the basolateral amygdala, which are often analyzed in studies of tangential migration of interneurons from the subpallial ganglionic eminences to the pallium/cortex. However, previous evidence suggests that during development the calbindin cells may include more than one of the interneuron subtypes found in the adult pallium/cortex. Furthermore, in the adult basolateral amygdala, calbindin cells include a subpopulation of non-GABAergic (non-interneuron) cells. To better characterize these cells throughout development, in the present study we investigated the colocalization of calbindin, parvalbumin and GABA in cells of the mouse basolateral amygdala during late embryonic (E16.5) and several postnatal ages from birth until 4 weeks after birth (P0, P10 and P28). Our results indicate that CB, PV and GABA show a dynamic pattern of colocalization in cells of the mouse basolateral amygdalar nucleus throughout development. From E16.5 through P28, the majority of CB+ neurons and virtually all PV+ neurons are GABAergic. However, after P10, the percentage of GABAergic CB+ cells decline from 96% to 70%. Furthermore, while only 9% of CB+ neurons are PV+ at P10, this percentage raises to 42% at P28. At all postnatal ages studied, the majority of the PV+ cells are CB+, suggesting that PV+ interneurons develop postnatally mainly as a subpopulation within the CB+ cells of the basolateral amygdalar nucleus. These results are important for interpreting data from interneuron migration.

    Immune dysfunction in astronauts is well documented after spaceflights. Microgravity is one of the key factors directly suppressing the function of immune system. However, it is unclear which subpopulations of immune cells including innate and adaptive immune cells are more sensitive to microgravity We herein investigated the direct effects of modeled microgravity (MMg) on different immune cells in vitro. Mouse splenocytes, thymocytes and bone marrow cells were exposed to MMg for 16 hrs. The survival and the phenotypes of different subsets of immune cells including CD4+T cells, CD8+T cells, CD4+Foxp3+ regulatory T cells (Treg), B cells, monocytes/macrophages, dendritic cells (DCs), natural killer cells (NK) were determined by flow cytometry. After splenocytes were cultured under MMg for 16h, the cell frequency and total numbers of monocytes, macrophages and CD4+Foxp3+T cells were significantly decreased more than 70 %. MMg significantly decreased the cell numbers of CD8+ T cells, B cells and neutrophils in splenocytes. The cell numbers of CD4+T cells and NK cells were unchanged significantly when splenocytes were cultured under MMg compared with controls. However, MMg significantly increased the ratio of mature neutrophils to immature neutrophils in bone marrow and the cell number of DCs in splenocytes. Based on the cell survival ability, monocytes, macrophages and CD4+Foxp3+Treg cells are most sensitive to microgravity; CD4+T cells and NK cells are resistant to microgravity; CD8+T cells and neutrophils are impacted by short term microgravity exposure. Microgravity promoted the maturation of neutrophils and development of DCs in vitro. The present studies offered new insights on the direct effects of MMg on the survival and homeostasis of immune cell subsets.

Being theoldest and most common race of natural shepherd dog, Turkish shepherd dog,Kangal, has survived with all characteristics of it mostly thanks to the matchlessprotection of local people of the town Kangal.Throughout the study, the main objective is to determine the folkloricknowledge related with Kangal raising within folklore of Sivas and to make somecontribution to Turkish world of culture.The research material has consisted of folkloric knowledge obtained between9th April-10th July, 2012 with “information review forms” applied to peopleassociated with folkloric veterinary medicine and animal husbandry in Sivas (e.g.medicine practitioners, animal owners, other resource persons, etc.In the study, it has been determined that raisers in Sivas folklore classify theKangals according to general racial characteristics, color of their pelt and tails ofthem. They are grouped as “kurtçul”, “saf”, “kırma”; and “alası-boz”, “karayaka”,“sarı yaka”, “boz yaka”, “kıllı”, “kırçıl”; and “kılıç kuyruk”, “kuyruğu eğri”, “kıvrakkuyruk”, based on racial characteristics, color of pelt and tails respectively. Also, ithas been gathered significant data on diseases and treatments on Kangals, generalracial standards (structure of the body, head and skull, etc., care and nutrition,estrus, delivery information, wolf choking incident, ear cut, stories, beliefs andidioms.Consequently, it can be suggested that one of reasons why Kangals havemanaged to keep its generation must be original stories and beliefs in Sivas, whichcover the Kangal`s wolf choke, intelligence, courage and loyalty; that lack ofknowledge

    Full Text Available ABSTRACT Objective: The aim of this study was to clarify the morphological differences in the mandibular arches of Turkish and North American white subjects. Methods: The sample included 132 Turkish (34 Class I, 58 Class II, and 40 Class III and 160 North American (60 Class I, 50 Class II, and 50 Class III subjects. The most facial portion of 13 proximal contact areas was digitized from photocopied images of patients' mandibular dental arches. Clinical bracket points were calculated for each tooth based on mandibular tooth thickness data. Four linear and two proportional measurements were taken. The subjects were grouped according to arch form types (tapered, ovoid and square in order to have frequency distribution compared between ethnic groups in each Angle classification. Results: The Turkish group showed significantly lower molar depth and more significant molar width-depth (W/D ratio in all three Angle classifications. On the other hand, the Turkish group also showed a significantly larger intercanine width in Class III malocclusion and intermolar width in Class II malocclusion. The most frequent arch forms seen were the ovoid arch form in the Turkish group and the tapered form in the white group. Conclusions: Our results demonstrate that when treating Turkish patients, one should expect to use preformed ovoid arch form orthodontic wires in a significant percentage of patients.

    This paper describes the behaviour disturbances and emotional problems of Turkish immigrant children aged 9 to 13 years living in Vienna. The children's behaviour was rated with Rutter's scales and the relationship of the results to any language problems, the socioeconomic situation and the sociocultural background of the immigrant families was then analyzed. A consecutive series of 111 Turkish and 25 Austrian children were rated by their parents and by both Turkish- and German-speaking teachers. Psychiatric symptoms of the children's parents were assessed with the symptom checklist SCL-90. The prevalence of behavior problems did not differ between the Turkish and Austrian children, who were of similar social class. The most common symptoms were restlessness, overactivity, poor concentration and anxiety. Whereas socioeconomic and sociocultural factors did not influence the frequency or severity of behavior problems in the Turkish children, there was a highly significant relationship between behavior problems and problems with German or Turkish. Moreover, the children very frequently had problems with both languages. Therefore intervention strategies with such children should focus on the language problems.

The most facial portion of 13 proximal contact areas was digitized from photocopied images of patients' mandibular dental arches. Clinical bracket points were calculated for each tooth based on mandibular tooth thickness data. Four linear and two proportional measurements were taken. The subjects were grouped according to arch form types (tapered, ovoid and square) in order to have frequency distribution compared between ethnic groups in each Angle classification. Results: The Turkish group showed significantly lower molar depth and more significant molar width-depth (W/D) ratio in all three Angle classifications. On the other hand, the Turkish group also showed a significantly larger intercanine width in Class III malocclusion and intermolar width in Class II malocclusion. The most frequent arch forms seen were the ovoid arch form in the Turkish group and the tapered form in the white group. Conclusions: Our results demonstrate that when treating Turkish patients, one should expect to use preformed ovoid arch form orthodontic wires in a significant percentage of patients. PMID:27275615

    There are two main types of layer V pyramidal neurons in rat cortex. Type I neurons have tufted apical dendrites extending into layer I, produce bursts of action potentials and project to subcortical targets (spinal cord, superior colliculus and pontine nuclei). Type II neurons have apical dendrites, which arborize in layers II-IV, do not produce bursts of action potentials and project to ipsilateral and contralateral cortex. The specific expression of different genes and proteins in these two distinct layer V neurons is unknown. To distinguish between distinct subpopulations, fluorescent microspheres were injected into subcortical targets (labeling type I neurons) or primary somatosensory cortex (labeling type II neurons) of adult rats. After transport, cortical sections were processed for immunohistochemistry using various antibodies. This study demonstrated that antigens recognized by SMI-32, N200 and FNP-7 antibodies were only expressed in subcortical (type I)--but not in contralateral (type II)--projecting neurons. NR1, NR2a/b, PLCbeta1, BDNF, NGF and TrkB antigens were highly expressed in all neuronal subpopulations examined. Organotypic culture experiments demonstrated that the development of neurofilament expression and laminar specificity does not depend on the presence of the subcortical targets. This study suggests specific markers for the subcortical projecting layer V neuron subpopulations.

    We examined the plasma lipids, lipoproteins, and selected apolipoproteins in approximately 9,000 men and women from six different regions of Turkey with markedly different diets, ranging from an Aegean coast diet high in olive oil (plasma cholesteryl ester fatty acids enriched in monounsaturated fatty acids) to an inland Anatolian diet high in meat and dairy products (plasma cholesteryl esters enriched in saturated fatty acids). The rural population consuming an olive oil-rich diet had the lowest plasma cholesterol levels (men, 149 mg/dl; women, 150 mg/dl). The urban populations of Istanbul and Adana had higher plasma cholesterol levels (men, 202 and 184 mg/dl, respectively; women, 181 and 190 mg/dl, respectively). Affluent men had the highest cholesterol levels (207 mg/dl). The low density lipoprotein (LDL) cholesterol levels tended to parallel the total cholesterol levels (highest for Istanbul men at 136 mg/dl and lowest for Aegean coast men and women at approximately 100 mg/dl). Strikingly, the Turkish people were found to have very low levels of high density lipoprotein (HDL) cholesterol (HDL-C) (mean values for all six regions: men, 34-38 mg/dl; women, 37-45 mg/dl) and total cholesterol/HDL-C ratios that were high (mean values for all six regions: men, 4.5-5.5; women, 3.9-5.0). The low HDL-C levels appear to be caused, at least in part, by a genetic factor. Triglyceride levels also tended to be high in Turkish men (approximately 120-150 mg/dl) and women (approximately 90-110 mg/dl). Thus, even though the total plasma cholesterol levels are not excessively elevated in comparison to those in other populations, the presence of low HDL-C or low HDL-C coupled with mildly elevated triglyceride levels may represent a significant risk factor for heart disease in the Turkish population. Affluence and higher education were associated with higher cholesterol levels. Lack of physical activity, smoking, and alcohol consumption also tended to be associated with a

    2008-08-01

    Home advantage is known to play an important role in the outcome of professional soccer games and to vary considerably worldwide. In the Turkish Super League over the last 12 years, 61.5% of the total points gained have been won by the home team, a figure similar to the worldwide average and to the Premier League in England. It is lower (57.7%) for games played between teams from Istanbul and especially high for games involving teams from cities in the more remote and ethnically distinct parts of Turkey (Van and Diyarbakir). Match performance data show that although home teams in Turkey take 26% more shots at goal than away teams, the success rates for shots do not differ. For fouls and disciplinary cards, home and away teams do not differ significantly in Turkey, a finding that differs from games in England, perhaps due to less referee bias.

    This descriptive study investigated the current status of ethics instruction in Turkish nursing education programs. The sample for this study comprised 39 nursing schools, which represented 51% of all nursing schools in Turkey. Data were collected through a postal questionnaire. The results revealed that 18 of these nursing schools incorporated an ethics course into undergraduate and three into graduate level programs. Most of the educators focused on the basic concepts of ethics, deontological theory, ethical principles, ethical problems in health care, patient rights and codes of ethics for nurses. More than half of the educators believed that students' theoretical knowledge of ethics is applied to their clinical experiences. The teaching methods used included discussion in class, lectures, case studies, small group discussion, dramatization and demonstration. Assessment was carried out by means of written essays and written examinations.

    Full Text Available One of the main objectives of military health services is to prevent suffering, injuries and death caused by wars which lead to great destructions on societies as much as possible. If the subject is considered for Turkish history, it is noted that personnel and duty processes of health services had an institutional feature and that duty was controlled by the government at Ottoman Empire. Public health practices, as a main component of military health services at both peace and war, has great importance. These practices should be determined thoroughly at peacetime by managers and preparations in that direction should be done and implemented. [TAF Prev Med Bull 2012; 11(1.000: 103-118

    Full Text Available Teachers’ motivation has been an extensive topic of discussion among researchers for over two decades. What has been missing in the discussion, though, is the perspective of those who teach English as a Foreign Language (EFL, especially those who work in Turkey. Therefore, the purpose of this case study was to investigate factors that motivated Turkish EFL teachers working at a Preparatory English Program of a university in Turkey and ways to enhance their motivation. Eight teachers took part in the study. To collect data, unstructured interviews were used. Then, codes were written and themes on teachers’ motivation and demotivation, and ways to motivate teachers emerged. The results can be understood by looking at expectancy theory, more specifically on the focus of the theory: intrinsic (personal and extrinsic (environmental motives. The analysis of what the teachers believed to be their source of motivation and demotivation helped the researcher to propose ways to enhance their motivation.

    Full Text Available Concentration is a situation in which market structure of a sector is controlled by a few firms. At the present time, many analyzing methods such as Herfindahl-Hirschman and N-Firm Concentration Indexes are used to determine market structure.According to market concentration indexes, higher concentration level means more monopolistic market structure, lower concentration level means more full competitive market structure. In this study concentration levels of media groups in Turkish journalism sector within the scope of traditional journalism and internet journalism was analyzed via N-Firm Concentration and H-H Indexes. As a result of the study, it’s seen that first four biggest media groups have monopolistic competition in internet journalism sector,and oligopol structure in traditional journalism sector. According to H-H index analyze, there is monopolistic competition in the sector.

    Full Text Available Firms should manage their customer feedback so they can adapt to rapid changes in the environment. They have to interact with their customers to understand them and to turn their opinions into useful knowledge. Understanding customers' feelings about a product gives firmS competitive advantage through continuous market monitoring. They can thus generate improving strategies about the system to change perceptions that drive the behaviours of the customers. Firms can view their customers' happiness as a key tool for decision-making. This study calculates online product happiness by using the average emotional valence values of customer opinions. We analyse Turkish opinions about a product over a period of 3 months. We find the averages of the online emotional valence values of the product per month. We also determined the increase in happiness over time. According to the opinion valence values, we found the relations between the documents.

    We have developed a method, called Meta-STEPP (subpopulation treatment effect pattern plot for meta-analysis), to explore treatment effect heterogeneity across covariate values in the meta-analysis setting for time-to-event data when the covariate of interest is continuous. Meta-STEPP forms overlapping subpopulations from individual patient data containing similar numbers of events with increasing covariate values, estimates subpopulation treatment effects using standard fixed-effects meta-analysis methodology, displays the estimated subpopulation treatment effect as a function of the covariate values, and provides a statistical test to detect possibly complex treatment-covariate interactions. Simulation studies show that this test has adequate type-I error rate recovery as well as power when reasonable window sizes are chosen. When applied to eight breast cancer trials, Meta-STEPP suggests that chemotherapy is less effective for tumors with high estrogen receptor expression compared with those with low expression.

    Full Text Available Abstract Background Since the sixties of the last century, many people from Morocco and Turkey have migrated into the Netherlands. In the last decade, Moroccan and Turkish patients have found their way to organizations for mental health care. However, they often drop out of treatment. Problems in the communication with therapists and different expectations regarding treatment seem to be causal factors for the early drop-out of therapy. In the Netherlands as in other countries courses have been developed for training cultural competence of therapists. Yet, up to now, the effectiveness of increased cultural competence of therapists in reducing drop-out of treatment has not been studied. Methods/Design A randomized clinical trial was started in January 2010. Moroccan and Turkish adult patients who are referred to our outpatient clinics for mood and anxiety disorders are randomly assigned to mental health workers who are trained in a cultural module and to those who are not. The therapists have been trained in the Cultural Formulation and in techniques bridging the (cultural gap between them and their Moroccan and Turkish patients. The target number of participants is 150 patients, 75 for each group. Drop-out of treatment is the primary outcome measure. Secondary outcome measures are no-show and patients' perspective of care. Discussion The study will give an answer to the question whether increasing cultural competence of therapists reduces drop-out of treatment in Moroccan and Turkish outpatients with depressive and anxiety disorders.

    In the present study, we tested whether the five identity statuses of the original Meeus-Crocetti model could be extracted in a Turkish sample. Their three-factor model of identity was used to examine identity formation. Participants were 1201 (59.6% females) youth aged between 12 and 24 years (Mage = 17.53 years, SDage = 3.25). Findings revealed that the five identity statuses extracted in previous studies (Crocetti, Rubini, Luyckx, & Meeus, 2008; Crocetti, Schwartz, Fermani, Klimstra, & Meeus, 2012) also emerged in a sample of Turkish adolescents and emerging adults. Findings indicated that gender and age affected the distribution of the individuals among the five identity statuses. Furthermore, individuals in the five identity statuses represented distinct profiles according to personality and self characteristics, problem behaviors and well-being, and interpersonal and group relationships. Finally, the status × age interactions indicated that the searching moratorium status became more problematic with age. Implications and suggestions for future research are also discussed.

    The purpose of this study was to test the reliability and validity of the Turkish Eating Assessment Tool (T-EAT-10) among patients with swallowing disorders. One hundred and five patients completed the T-EAT-10 and Functional Oral Intake Scale (FOIS). The internal consistency, test-retest reliability, and criterion validity of T-EAT-10 were investigated. The internal consistency was assessed using Cronbach's alpha. Intraclass correlation coefficient (ICC) value with 95 % confidence intervals was calculated for test-retest reliability. The criterion validity of the T-EAT-10 was determined by assessing the correlation between T-EAT-10 and FOIS. All the patients in the study completed the T-EAT-10 without assistance. The mean time to complete the instrument was 1.8 ± 0.9 min. The internal consistency of the T-EAT-10 was found to be high with 0.90 Cronbach's alpha for test and 0.91 Cronbach's alpha for retest reproducibility. No difference between the test and retest scores of the T-EAT-10 was found (p = 0.14). A negative, moderate correlation between T-EAT-10 and FOIS was detected (r = -0.365, p EAT-10 is a reliable and valid symptom-specific outcome tool for dysphagia in adult Turkish patients. It can be used in clinical practice and research.

    In the hippocampus, the synaptic vesicle protein synaptoporin (SPO) has been reported to be exclusively enriched in the granule cell axons, the mossy fibers. In this study, we show that in adult rats and mice SPO immunoreactivity (IR) is also detectable in strata oriens, radiatum, and lacunosum-moleculare of CA1-CA3, as well as perisomatically in the hippocampus proper and fascia dentata. In situ hybridization confirmed that SPO mRNA was present in granule cells and CA3 pyramidal cells but not in CA1 pyramidal cells. Importantly, cells scattered throughout the hippocampal layers resembling the distribution of interneurons were found to synthesize high amounts of SPO mRNA, too. Thus, these findings indicate that SPO expression in the hippocampus was underestimated until now. Moreover, double-labeling immunohistochemistry and confocal microscopy revealed selective colocalization of SPO and glutamate decarboxylase (GAD 65), a marker for gamma-aminobutyric acid (GABA)ergic terminals. To identify SPO expressing interneurons, in situ hybridization was combined with immunocytochemistry against parvalbumin (PV), calbindin (CB), calretinin (CR), cholecystokinin (CCK), and vasoactive intestinal polypeptide (VIP). We found that SPO transcripts were differentially expressed by various interneuron subpopulations in the hippocampus of C57Bl/6 mice (PV 44.2%, CB 46.3%, CR 19.3%, CCK 38.6%, VIP 59.9%). Immunoelectron microscopy for SPO labeled synaptic vesicle profiles in distinct symmetric and asymmetric synapses. In conclusion, our data demonstrate that hippocampal principal cells and interneurons display a variety of synaptic vesicles that are likely to contribute to the functional characteristics of their output synapses.

  9. NEGATIVE CURRENCY-RISK-EXPOSURE FOR TURKISH EQUITIES

    Full Text Available Currency-risk-exposure is an issue for Turkish equities, from two different angles: internationaltrade and foreign-portfolio-investment. The likely effect is positive for the former, and negative for the latter aspect. Consequently, the overall or net effect on equity value depends on which of these aspects of currency-risk-exposure has the greater impact. The present empirical analysis estimates currency risk of Turkish equities within a multi-factor regression setting, utilizing the framework of the Security Market Plane (SMP model. The SMP model embodies a conditional relation among three variables: beta, realized excess market-return, and expected excess portfolio-return. The SMP empirical framework is extended to include a currency-risk-factor in the present analysis. The currency-risk-factor is specified as the excess return to holding foreign currency (€; $, relative to holding domestic currency (Turkish Lira. The SMP-related factor is the cross-product term of beta and realized excess market-return (β it rMt . A regression of realized excess portfolio-returns against the corresponding currency-risk-factor and cross product-term (β it rMt finds that the Turkish stocks represented in the analysis generally have overall negative currency-risk-exposure; suggesting that unexpected currency depreciation generally leads to lower values for Turkish stocks (and portfolios of Turkish stocks. Thus, after accounting for the SMP-related interaction-effect between beta and realized excess marketreturn, currency risk is found to command a premium for the Turkish stocks represented in the analysis.

    The main aim of this study is to assess the influence of freeze/thawing on motile sperm subpopulations in ejaculates from two phylogenetically different mammalian species, boar and donkey. Our results indicate that, whereas boar and donkey sperm respond very differently in their mean motion characteristics to freezing/thawing, this process did not change the existence of a 4-subpopulations structure in the ejaculates in either species when these subpopulations were defined by taking values of curvilinear velocity (VCL) as reference. Moreover, the freezing/thawing-linked changes in mean sperm-motion characteristics in both boar and donkey semen were especially due to changes in the proportion among each concrete subpopulation. In this way, the freezing/thawing-induced mean increase in motion characteristics observed in boar sperm was a result of the decrease in the percentage of sperm in Subpopulation 1 (from 53.9%+/-4.7% to 31.2%+/-3.9% after thawing) and a concomitant increase of sperm from Subpopulations 3 (from 13.3%+/-2.5% to 32.6%+/-3.9% after thawing) and 4 (from 3.4%+/-0.9% to 8.0%+/-1.1% after thawing). On the contrary, changes in mean motility of frozen/thawed donkey sperm were linked to an increase in the percentage of sperm in Subpopulation 1 (from 31.5%+/-4.3% to 58.8%+/-4.9% after thawing) and a concomitant decrease of sperm from Subpopulations 3 (from 32.4%+/-3.2% to 6.6%+/-1.8% after thawing) and 4 (from 12.2%+/-2.5% to 7.3%+/-1.9% after thawing). In conclusion, our results seem to indicate that motility changes induced by the freezing/thawing protocol are linked to concomitant changes in both the specific parameters and, more importantly, to the specific percentage of each of the motile sperm subpopulations. These changes did not affect the overall proportion of motile sperm present in both boar and donkey, which is conserved despite the detrimental effect caused by freezing/thawing in both species. Finally, the presence of some kind of motile sperm

    Castanea squinii Dode,an endemic tree widely distributed in China,plays an important role both in chestnut breeding and forest ecosystem function.The spatial genetic structure within and among populations is an important part of the evolutionary and ecological genetic dynamics of natural populations,and can provide insights into effective conservation of genetic resources.In the present study,the spatial genetic structure of a panmictic natural population of C.sequinii in the Dabie Mountain region was investigated using microsatellite markers.Nine prescreened microsatellite loci generated 29-33 alleles each,and were used for spatial autocorrelation analysis.Based on Moran's I coefficient,a panmictic population of C.sequinii in the Dabie Mountain region was found to be lacking a spatial genetic structure.These results suggest that a high pollen-mediated gene flow among subpopulations counteract genetic drift and/or genetic differentiation and plays an important role in maintaining a random and panmictic population structure in C.sequinii populations.Further,a spatial genetic structure was detected in each subpopulation's scale (0.228 km),with all three subpopulations showing significant fine-scale structure.The genetic variation was found to be nonrandomly distributed within 61 m in each subpopulation (Moran's I positive values).Although Moran's I values varied among the different subpopulations,Moran's I in all the three subpopulations reached the expected values with an increase in distances,suggesting a generally patchy distribution in the subpopulations.The fine-scale structure seems to reflect restricted seed dispersal and microenvironment selection in C.sequinii.These results have important implications for understanding the evolutionary history and ecological process of the natural population of C.sequinii and provide baseline data for formulating a conservation strategy of Castanea species.

    This work provides information on the blue fox ejaculated sperm quality needed for seminal dose calculations. Twenty semen samples, obtained by masturbation, were analyzed for kinematic and morphometric parameters by using CASA-Mot and CASA-Morph system and principal component (PC) analysis. For motility, eight kinematic parameters were evaluated, which were reduced to PC1, related to linear variables, and PC2, related to oscillatory movement. The whole population was divided into three independent subpopulations: SP1, fast cells with linear movement; SP2, slow cells and nonoscillatory motility; and SP3, medium speed cells and oscillatory movement. In almost all cases, the subpopulation distribution by animal was significantly different. Head morphology analysis generated four size and four shape parameters, which were reduced to PC1, related to size, and PC2, related to shape of the cells. Three morphometric subpopulations existed: SP1: large oval cells; SP2: medium size elongated cells; and SP3: small and short cells. The subpopulation distribution differed between animals. Combining the kinematic and morphometric datasets produced PC1, related to morphometric parameters, and PC2, related to kinematics, which generated four sperm subpopulations – SP1: high oscillatory motility, large and short heads; SP2: medium velocity with small and short heads; SP3: slow motion small and elongated cells; and SP4: high linear speed and large elongated cells. Subpopulation distribution was different in all animals. The establishment of sperm subpopulations from kinematic, morphometric, and combined variables not only improves the well-defined fox semen characteristics and offers a good conceptual basis for fertility and sperm preservation techniques in this species, but also opens the door to use this approach in other species, included humans.

The whole population was divided into three independent subpopulations: SP1, fast cells with linear movement; SP2, slow cells and nonoscillatory motility; and SP3, medium speed cells and oscillatory movement. In almost all cases, the subpopulation distribution by animal was significantly different. Head morphology analysis generated four size and four shape parameters, which were reduced to PC1, related to size, and PC2, related to shape of the cells. Three morphometric subpopulations existed: SP1: large oval cells; SP2: medium size elongated cells; and SP3: small and short cells. The subpopulation distribution differed between animals. Combining the kinematic and morphometric datasets produced PC1, related to morphometric parameters, and PC2, related to kinematics, which generated four sperm subpopulations - SP1: high oscillatory motility, large and short heads; SP2: medium velocity with small and short heads; SP3: slow motion small and elongated cells; and SP4: high linear speed and large elongated cells. Subpopulation distribution was different in all animals. The establishment of sperm subpopulations from kinematic, morphometric, and combined variables not only improves the well-defined fox semen characteristics and offers a good conceptual basis for fertility and sperm preservation techniques in this species, but also opens the door to use this approach in other species, included humans.

    Full Text Available Latest global financial crisis that shrank the credit market affected the companies’ financial policies since the credit contraction led the firms to rely more on their own resources rather than external financing. The expectation during such crises is more equity issues along with less borrowing. In economic literature there are some evidence supporting this fact for developed countries. As an emerging country Turkey’s case is different than that of advanced countries. The era commenced with Lehman turmoil by passed Turkish economy in the first years due to the solid, strong and healthy banking sector due to the measurements taken after 2001 banking crisis of Turkey. Therefore, international lenders did not hesitate directing their funds to Turkish banks. As a result, Turkish companies did not suffer in financing their investments through bank loans. Moreover, the growth policy of Turkey based on current account deficit supported Turkish economy and in turn the firms due to the abundance of liquidity after the peak of the crisis. In this work we examined 164 industrial firms that are traded on Borsa Istanbul to see if there happened to be a shift in their financing preferences during the recent global crisis. We found that the importance of borrowing had not decreased and that contradicts the expectations. As of equity issues, before and after 2009 no radical change has been observed. In 2009 where the crisis hit worst Turkish economy leading a 4.7% GDP decrease, the equity issues were doubled.

    Full Text Available Abstract Background A variety of cell types can be identified in the adherent fraction of bone marrow mononuclear cells including more primitive and embryonic-like stem cells, mesenchymal stem cells (MSC, lineage-committed progenitors as well as mature cells such as osteoblasts and fibroblasts. Different methods are described for the isolation of single bone marrow stem cell subpopulations – beginning from ordinary size sieving, long term cultivation under specific conditions to FACS-based approaches. Besides bone marrow-derived subpopulations, also other tissues including human umbilical cord (UC have been recently suggested to provide a potential source for MSC. Although of clinical importance, these UC-derived MSC populations remain to be characterized. It was thus the aim of the present study to identify possible subpopulations in cultures of MSC-like cells obtained from UC. We used counterflow centrifugal elutriation (CCE as a novel strategy to successfully address this question. Results UC-derived primary cells were separated by CCE and revealed differentially-sized populations in the fractions. Thus, a subpopulation with an average diameter of about 11 μm and a small flat cell body was compared to a large sized subpopulation of about 19 μm average diameter. Flow cytometric analysis revealed the expression of certain MSC stem cell markers including CD44, CD73, CD90 and CD105, respectively, although these markers were expressed at higher levels in the small-sized population. Moreover, this small-sized subpopulation exhibited a higher proliferative capacity as compared to the total UC-derived primary cultures and the large-sized cells and demonstrated a reduced amount of aging cells. Conclusion Using the CCE technique, we were the first to demonstrate a subpopulation of small-sized UC-derived primary cells carrying MSC-like characteristics according to the presence of various mesenchymal stem cell markers. This is also supported by the

    In this study we analyzed the chondrogenic potential of subpopulations of mesenchymal stem cells (MSCs) derived from human synovial membranes enriched for CD73, CD106, and CD271 markers. Subpopulations of human synovial membrane MSCs enriched for CD73, CD106, and CD271 markers were isolated using a cytometry sorter and characterized by flow cytometry for MSC markers. The expression of Sox9, Nanog, and Runx2 genes by these cells was measured by reverse transcriptase-polymerase chain reaction. The chondrogenesis of each subpopulation was assessed by culturing the cells in a defined medium to produce spontaneous spheroid formation and differentiation towards chondrocyte-like cells. The examination of the spheroids by histological and immunohistochemical analyses for collagen type II (COL2), aggrecan, collagen type I (COL1), metalloprotease 13 (MMP13), and collagen type X (COLX) levels were performed to assess their chondrogenesis capacity. The adipogenesis and osteogenesis potential of each subpopulation was determined using commercial media; the resulting cells were stained with oil red O or red alizarin to test the degree of differentiation. The subpopulations had different profiles of cells positive for the MSC markers CD44, CD69, CD73, CD90, and CD105 and showed different expression levels of the genes Sox9, Nanog, and Runx2 involved in chondrogenesis, undifferentiation, and osteoblastogenesis, respectively. Immunohistochemical analysis demonstrated that COL1, COL2, COLX, MMP13, and aggrecan were expressed in the spheroids as soon as 14 days of culture. The CD271(+) subpopulation expressed the highest levels of COL2 staining compared to the other subpopulations. CD105 and Runx2 were shown by immunohistochemistry and genetic analysis to have significantly higher expression CD271(+) subpopulation than the other subpopulations. Spheroids formed from CD271-enriched and CD73-enriched MSCs from normal human synovial membranes mimic the native cartilage extracellular

    Full Text Available Putrescine, spermidine and spermine are the most abundant polycationic natural amines found in nearly all organisms. They are involved in regulation of gene expression, translation, cell proliferation and differentiation. They can be supplied by the endogenous synthesis inside the cell or by the intake from exogenous sources. There is a growing body of literature associated with the effects of bioactive amines on health and diseases, but limited information about polyamine content in foods is available. In the present study, the polyamine content of frequently consumed foods in a typical Turkish diet was estimated for adults, including tea, bread and yoghurt. The estimation of daily intake was defined as 93,057 nmol/day putrescine, 33,122 nmol/day spermidine, 13,685 nmol/day spermine. The contribution of foods to daily intake was: dairy products (47.32%, vegetables and grains (21.09% and wheat products (12.75%.

    Analysis of the globular cluster (GC) system of the giant elliptical (E3) galaxy NGC 4365, from eight Hubble Space Telescope/Advanced Camera for Surveys (ACS) pointings and a wide-field Subaru/SuprimeCam (S-Cam) image, is presented. We determine the lower limit on the number of GCs to be 6450+-110 and show that the GC system extends beyond 134 kpc (9.5 galaxy effective radii). We revisit the question of whether NGC 4365 has a bimodal or trimodal GC colour distribution and find support for three distinct GC colour subpopulations (i.e. blue, green and red). Sersic profile fits to the radial surface density of each subpopulation reveal that the blue GCs are more extended than either red or green GCs. We find significant differences in the median half light radii for GCs in the blue, green and red subpopulations as well as in the subpopulation ellipticities. A KS test on the mass functions show >98 per cent probability that all three subpopulations are distinct from one another. We also find radial gradients of G...

  2. Quantitative analysis of monocyte subpopulations in murine atherosclerotic plaques by multiphoton microscopy.

    Abigail S Haka

    Full Text Available The progressive accumulation of monocyte-derived cells in the atherosclerotic plaque is a hallmark of atherosclerosis. However, it is now appreciated that monocytes represent a heterogeneous circulating population of cells that differ in functionality. New approaches are needed to investigate the role of monocyte subpopulations in atherosclerosis since a detailed understanding of their differential mobilization, recruitment, survival and emigration during atherogenesis is of particular importance for development of successful therapeutic strategies. We present a novel methodology for the in vivo examination of monocyte subpopulations in mouse models of atherosclerosis. This approach combines cellular labeling by fluorescent beads with multiphoton microscopy to visualize and monitor monocyte subpopulations in living animals. First, we show that multiphoton microscopy is an accurate and timesaving technique to analyze monocyte subpopulation trafficking and localization in plaques in excised tissues. Next, we demonstrate that multiphoton microscopy can be used to monitor monocyte subpopulation trafficking in atherosclerotic plaques in living animals. This novel methodology should have broad applications and facilitate new insights into the pathogenesis of atherosclerosis and other inflammatory diseases.

    It has been shown that a malignant tumor is akin to a complex organ comprising of various cell populations including tumor cells that are genetically, metabolically and functionally different. Our redox imaging data have demonstrated intra-tumor redox heterogeneity in all mouse xenografts derived from human melanomas, breast, prostate, and colon cancers. Based on the signals of NADH and oxidized flavoproteins (Fp, including flavin adenine dinucleotide (FAD)) and their ratio, i.e., the redox ratio, which is an indicator of mitochondrial metabolic status, we have discovered several distinct redox subpopulations in xenografts of breast tumors potentially recapitulating functional/metabolic heterogeneity within the tumor. Furthermore, xenografts of breast tumors with higher metastatic potential tend to have a redox subpopulation whose redox ratio is significantly different from that of tumors with lower metastatic potential and usually have a bi-modal distribution of the redox ratio. The redox subpopulations from human breast cancer samples can also be very complex with multiple subpopulations as determined by fitting the redox ratio histograms with multi- Gaussian functions. In this report, we present a new method for identifying the redox subpopulations within individual breast tumor xenografts and human breast tissues, which may be used to differentiate between breast cancer and normal tissue and among breast cancer with different risks of progression.

    Full Text Available Aim. The aim of this study was to evaluate by means of radiographs the technical quality of root fillings performed by dental practitioners. Methods and Material. Standardized periapical radiographs were made on 484 patients who received endodontic treatment in private practice. A total of 831 endodontically treated teeth with 1448 roots were evaluated for technical quality of the root canal filling and the periapical status of the teeth. Also, the apical status of each root-filled tooth was assessed according to the length, density, and taper of root fillings, and the presence of apical transportation, broken root instruments, and overfilled sealer or gutta-percha material was recorded for each root canal. Results. Of the endodontically treated teeth 26.6% had healthy periapical tissues, while technically good endodontic treatment constituted 12.8%. Based on the treatment success, there was no significant difference between the tooth groups. Statistical analysis of the data did not demonstrate statistically significant differences between the various parameters that were evaluated (. Conclusions. Technical quality of root fillings in a population who received treatment in private practice was poor and was consistent with a low prevalence of apical health. The probable reasons for this failure are multifactorial and may be improved if the operators improve their skills with continuing postgraduate education programs.

    2010-01-01

    This article investigates the reciprocal influence of Ottoman Turkish and American interiors in the development of seating furniture. Seating furniture is unique because it involves a direct and physical interaction between the piece of furniture and the body, while at the same time it is part of a public space where social interactions occur. I will argue that the interactions between the Ottoman Turks and Americans are reflected in the way these traditions modified their seating furniture as they sought to mediate cultural, political and social differences between them. The concept of bodily comfort will serve as a common thread in understanding the origin of the expression "American style" (Amerikan stili or Amerikan tarzı) in modern Turkish language, the "Turkish chairs" in Victorian America in the late nineteenth century and the English language use of words such as sofa, ottoman and divan.

  9. Generating Context-Appropriate Word Orders in Turkish

    Hoffman, B

    1994-01-01

    Turkish has considerably freer word order than English. The interpretations of different word orders in Turkish rely on information that describes how a sentence relates to its discourse context. To capture the syntactic features of a free word order language, I present an adaptation of Combinatory Categorial Grammars called {}-CCGs (set-CCGs). In {}-CCGs, a verb's subcategorization requirements are relaxed so that it requires a set of arguments without specifying their linear order. I integrate a level of information structure, representing pragmatic functions such as topic and focus, with {}-CCGs to allow certain pragmatic distinctions in meaning to influence the word order of a sentence in a compositional way. Finally, I discuss how this strategy is used within an implemented generation system which produces Turkish sentences with context-appropriate word orders in a simple database query task.

    This study was designed to assess the incidence of low back pain among Turkish coal miners and to investigate the relationship between angles of the lumbar spine and low back pain in coal miners. Fifty underground workers (Group I) and 38 age-matched surface workers (Group II) were included in the study. All the subjects were asked about low back pain in the past 5 years. The prevalence of low back pain was higher in Group I than in Group II (78.0%, 32.4%, respectively, P {lt} 0.001). The results of the study showed that low back pain occurred in 78.0% of Turkish coal miners. Although the nature of the occupation may have influenced coal miners' lumbar spinal curvature, lumbar angles are not a determinant for low back pain in this population. Further extensive studies involving ergonomic measurements are needed to validate our results for Turkish coal mining industry.

    Full Text Available Introduction. As one of mesophilic, easily cultivated species of pathogenic bacteria, Salmonella enterica transformed into viable but nonculturable (VNC state in response to environmental stresses, including action of biocides. The cells in this state, preserve the integrity of membranes and metabolism of some, but not detected by conventional methods of cultivation. Some researchers suggest that the evolutionary significance of this phenomenon is part of an adaptive response aimed at long-term survival of bacteria in adverse conditions; others argue that it is the result of stochastic cellular damage, in which nonculturable cells are in a state of gradual death. In any case, the phenomenon of existence VNC pathogens if they retain the ability to restore its growth in vivo is a significant problem in medicine, pharmaceutical, veterinary, food industry. VNC subpopulation of S. enterica was obtained under action of ethanol. In this paper was investigated in vivo resuscitation VNC S. enterica using intraperitoneal injection of mice.

    Mild hepatic iron overload has been demonstrated by magnetic susceptibility measurements in a 22-year-old man with hereditary sideroblastic erythropoiesis despite hemoglobin levels in the normal range and a normal erythropoietin level. His grandfather's sideroblastic anemia has been found to be responsive to pyridoxine; his mother's hemoglobin has persisted in the normal range but red cell volume distribution analysis demonstrated two subpopulations; 30% with estimated geometric mean of 68 fl and 70% an estimated mean of 93 fl. Red cell distribution analysis of the grandson demonstrated two microcytic subpopulations; 46% with an estimated geometric mean of 45 fl and 54% an estimated mean of 70 fl. A therapeutic regimen is outlined to reduce to normal his iron stores and to prevent the future development of excessive iron overload.

    Leishmania species trigger a brisk inflammatory response and efficiently induce cell-mediated immunity. We examined the mechanisms whereby leukocytes were recruited into lesions after Leishmania major infection of mice. We found that a subpopulation of effector monocytes expressing the granulocyte marker GR1 (Ly6C) is rapidly recruited into lesions, and these monocytes efficiently kill L. major parasites. The recruitment of this subpopulation of monocytes depends on the chemokine receptor CCR2 and the activation of platelets. Activated platelets secrete platelet-derived growth factor, which induces the rapid release of CCL2 from leukocytes and mesenchymal cells. This work points to a new role for platelets in host defense involving the selective recruitment of a subpopulation of effector monocytes from the blood to efficiently kill this intracellular parasite.

    Full Text Available Background: While previous studies have demonstrated the efficacy of tobacco control interventions in reducing tobacco use among youth overall, there have been very few studies that examine the potential differential impact of tobacco control policies on various youth subgroups, defined by socio-economic status (SES, race/ethnicity, and gender. Objective: We examined the relationship between state-level cigarette prices and smoke-free air laws and youth smoking prevalence and intensity for various youth sub-populations in the United States. Methods: We estimated a 2-part model of cigarette demand using data from the 1991 through 2010 nationally representative surveys of 8th-, 10th-, and 12th-grade students as part of the Monitoring the Future project. Findings: We found that real cigarette prices are strong determinants of youth smoking. Blacks, females, Hispanics, and low-SES subpopulations are found to have a larger price response with respect to smoking prevalence than the full sample. Smoke-free air laws are found to have a negative effect on smoking prevalence for the full sample and for the male, white, and high-SES sub-populations. Conclusions: This research concludes that higher cigarette prices will reduce smoking prevalence rates of Blacks, Hispanics, females, and low-SES subpopulations faster than the overall youth population and other youth sub-populations. Moreover, this research concludes that smoke-free air laws will reduce smoking prevalence for the overall youth population with the largest reductions in high SES and male subpopulations.

Lexicology looks after to prepare not only for general purpose lexicon for mother tongue users but also particular purpose lexicons for special aims (e.g. proverbs and idioms dictionary, terms dictionary, synonym words dictionary, antonym words dictionary, collocation dictionary etc.. Today, when the studies are considered about the vocabulary of Turkey Turkish, general purpose lexicon works, and particular purpose lexicons for special aim works are insufficient and limited. In lexicology, collocation dictionary is one of the main products of lexicology, seen as a non mentioned subject at the study of Turkey Turkish vocabulary. On the other hand, in lexicology, collocation has been taken place in literature as an important applying method, especially in the corpus linguistics applications and defining the stage of preferences in language teaching.This study’s object is to investigate the collocations in a corpus-based approach, is defined as adjective and lexicalized 11.320 lexemes as headword in Türkçe Sözlük (Turkish Dictionary which is including the vocabulary of Turkey Turkish. This study has speciality is being the first, about purpose, content and method also executing by experienced researchers at similar studies. The anticipated outcomes of this study are as follows: 1.It will be defined the adjectives’s syntactic features which have intense usage in generally language and especially in Turkey Turkish. 2.It will be made semantic and syntactic corpus-control of adjectives in Türkçe Sözlük (Turkish Dictionary which is including the vocabulary of Turkey Turkish. 3.It will be defined the concept domains of adjectives-noun and noun-adjectives relationship in Turkish. 4.It will be defined the adjective-noun usages based by frequency appearance relationships about mother tongue and second language teaching for Turkish. 5.It will be collected main

    In this study, Oak Ridge National Laboratory (ORNL) was tasked by the NYS Department of Transportation (DOT) to conduct a detailed examination of travel behaviors, and identify patterns and trends, on several NYS subpopulations, including disabled persons. Unlike other studies that concentrated on national level statistics, this research is focused on examining issues associated with travelers among NYS residents only. For each special subpopulation group, ORNL will identify differences, if any, in travel patterns that are attributable to demographic characteristics, household characteristics, modal characteristics, geographic location, and other concepts. Focus will be given to trip frequency, trip chaining, as well as travel by time of day, trip purpose, and mode choice.

    2011-01-01

    Each of the three Th2 cytokine genes, IL-4, IL-5, and IL-13, has different functions. We hypothesized that Th2 heterogeneity could yield Th2 subpopulations with different cytokine expression and effector functions. Using multiple approaches we demonstrate that human Th2 cells are composed of two major subpopulations: a minority IL-5+ (IL-5+, IL-4+, IL-13+) and majority IL-5− Th2 (IL-5−, IL-4+, IL-13+) population. IL-5+ Th2 cells comprised only 20% of all Th2 cells.Serial rounds of in vitro di...

    Full Text Available Head and neck squamous carcinoma (HNSCC tumors carry dismal long-term prognosis and the role of tumor initiating cells (TICs in this cancer is unclear. We investigated in HNSCC xenografts whether specific tumor subpopulations contributed to tumor growth. We used a CFSE-based label retentions assay, CD49f (α6-integrin surface levels and aldehyde dehydrogenase (ALDH activity to profile HNSCC subpopulations.

While only sorted CD49f(high/ALDH(high, label retaining cells (LRC proliferated immediately in vivo, with time the CD49f(low/ALDH(low, non-LRC (NLRC tumor cell subpopulations were also able to regain tumorigenic capacity; this was linked to restoration of CD49f(high/ALDH(high, label retaining cells. In addition, CD49f is required for HEp3 cell tumorigenicity and to maintain low levels of H3K4/K27me3. CD49f+ cells also displayed reduced expression of the histone-lysine N-methyltransferase EZH2 and ERK1/2 phosphorylation. This suggests that although transiently quiescent, their unique chromatin structure is poised for rapid transcriptional activation. CD49f- cells can "reprogram" and also achieve this state eventually. We propose that in HNSCC tumors, epigenetic mechanisms likely driven by CD49f signaling dynamically regulate HNSCC xenograft phenotypic heterogeneity. This allows multiple tumor cell subpopulations to drive tumor growth suggesting that their dynamic nature renders them a "moving target" and their eradication might require

    2016-01-01

    To assess genetic diversity and maternal origin of Turkish and Iranian native chicken breeds, we analyzed the mtDNA D-loop sequences of 222 chickens from 2 Turkish (Denizli and Gerze) and 7 Iranian (White Marandi, Black Marandi, Naked Neck, Common Breed, Lari, West Azarbaijan, and New Hampshire) native chicken breeds, together with the available reference sequences of G. gallus gallus in GenBank. The haplotype diversity was estimated as 0.24±0.01 and 0.36±0.02 for Turkish and Iranian populations, respectively. In total, 19 haplotypes were observed from 24 polymorphic sites in Turkish and Iranian native chicken populations. Two different clades or haplogroups (A and E) were found in Turkish and Iranian chickens. Clade A haplotypes were found only in White Marandi, Common Breed and New Hampshire populations. Clade E haplotypes, which are quite common, were observed in Turkish and Iranian populations with 18 different haplotypes, of which Turkish and Iranian chickens, Clade E, haplotype 1 (TRIRE1) was a major haplotype with the frequency of 81.5% (181/222) across all breeds. Compared to red jungle fowl, Turkish and Iranian chicken breeds are closely related to each other. These results suggest that Turkish and Iranian chickens originated from the same region, the Indian subcontinent. Our results will provide reliable basic information for mtDNA haplotypes of Turkish and Iranian chickens and for studying the origin of domestic chickens. PMID:27189637

    Full Text Available Turkish is a language with rapid expansion and influence and it is taught within the country and abroad as a foreign language. Recent years studies on the teaching Turkish as foreign language indicate that requirements of learning “Business” Turkish are in increase. Thus, in the studies on Turkish as foreign language teaching there is necessity for development of special curriculum, preparation of the course books and materials suitable to the curriculum for the creation of the “Business Turkish” field. In the studies for the Business Turkish it is initially important the identification of necessary business branches. There are a lot of Turkish banks providing services abroad. These banks including Turkish citizens, strive to employ Turkish language speakers or require from their current personnel to learn Turkish. Due to the personnel’s limited time for attending the courses and learning Turkish in the level as much as being able to serve the clients, we have focused in “Banking” example. Thus we prepared sample curriculum and glossary, as well as specified the issues to focus on in the course books.

    Full Text Available Turkish people, who have a long historical background, have a rich culture in terms of cuisine. “Dolma” (meal made by stuffing/wrapping is one of the most important dishes of the Turkish Cuisine. Turks produced very different types of meals made by stuffing or wrapping and by combining herbals, meat and offals products. Stuffed Lamb Ribs (in Turkish; Kaburga Dolması or Sura is a special dish that is known in many regions of Turkey. Since it is a dish whose preparation is hard and requires virtuosity, it is generally cooked as a feast meal on religious holidays, and commonly cooked on the Feast of Sacrifice for Muslims. This study aims to present how “Stuffed Lamb Ribs” are prepared, which is one of the traditional dishes of Turkish Cuisine and is one stuffed dish that has started to become forgotten. In this study, the data was collected by personal interviews with source people who are over 60 years old, live in different provinces of Turkey, and traditionally cook this dish.

    2009-12-01

    This study evaluated the psychometric properties of the Codependency Assessment Tool (CODAT) developed by C. Hughes Hammer, D. S. Martsolf, and R. A. Zeller (1998a, 1998b) for Turkish students and investigated the relationship of codependency with attachment styles and family problems. After the translation of the CODAT, Beck Depression Inventory, Experiences in Close Relationships-Revised, and Family Problems of Young Adulthood Evaluation Scale, each was administrated to Turkish female nurse students (n = 400). Factor analysis and Cronbach's alpha values were then computed. Five-factor solution revealed a similar factor structure for the Turkish version of CODAT compared with that of the original tool. Five factors explained 48.38% of the variance. All of the items (with one exception) loaded on their original factors. Cronbach's alpha values for factors ranged between .62 and .78. For the total score, Cronbach's alpha was found to be .75. After statistically controlling for the effects of depressive symptoms, analysis of covariance (ANCOVA) was conducted to investigate if the attachment styles and family problems would change depending on codependency levels. For ANCOVAs, CODAT scores were treated at three levels. Students with higher CODAT scores had more attachment-related anxiety and reported more family problems after controlling for the effects of depressive symptoms. Our research results support the internal consistency and validity of the Turkish version of CODAT.

    Understanding habitat requirements and identifying landscape linkages are essential for the survival of isolated populations of endangered species. Currently, some of the giant panda populations are isolated, which threatens their long-term survival, particularly in the Xiaoxiangling mountains. In the present study, we quantified niche requirements and then identified potential linkages of giant panda subpopulations in the most isolated region, using ecological niche factor analysis and a least-cost path model. Giant pandas preferred habitat with conifer forest and gentle slopes (>20 to ≤30°). Based on spatial distribution of suitable habitat, linkages were identified for the Yele subpopulation to 4 other subpopulations (Liziping, Matou, Xinmin and Wanba). Their lengths ranged from 15 to 54 km. The accumulated cost ranged from 693 to 3166 and conifer forest covered over 31%. However, a variety of features (e.g. major roads, human settlements and large unforested areas) might act as barriers along the linkages for giant panda dispersal. Our analysis quantified giant panda subpopulation connectivity to ensure long-term survival.

    The extent to which individual neurons are interconnected selectively within brain circuits is an unresolved problem in neuroscience. Neurons can be organized into preferentially interconnected microcircuits, but whether this reflects genetically defined subpopulations is unclear. We found that the principal neurons in the main subdivisions of the hippocampus consist of distinct subpopulations that are generated during distinct time windows and that interconnect selectively across subdivisions. In two mouse lines in which transgene expression was driven by the neuron-specific Thy1 promoter, transgene expression allowed us to visualize distinct populations of principal neurons with unique and matched patterns of gene expression, shared distinct neurogenesis and synaptogenesis time windows, and selective connectivity at dentate gyrus-CA3 and CA3-CA1 synapses. Matched subpopulation marker genes and neuronal subtype markers mapped near clusters of olfactory receptor genes. The nonoverlapping matched timings of synaptogenesis accounted for the selective connectivities of these neurons in CA3. Therefore, the hippocampus contains parallel connectivity channels assembled from distinct principal neuron subpopulations through matched schedules of synaptogenesis.

    Full Text Available Introduction: The aim of the study was to evaluate the effect of administration of therapeutic doses of ceftiofur and tulathromycin on the circulating lymphocyte subpopulations in healthy pigs. Material and Methods: The study was conducted on thirty healthy 7- to 10-week-old pigs, assigned to three groups: the TUL group, injected with tulathromycin (n = 10; the CEF group, injected with ceftiofur (n = 10; and the C group, the control with no antibiotic administration (n = 10. Blood samples were collected before, during, and after treatment with antimicrobials. Lymphocyte subpopulations circulating in the blood were determined by immunostaining and flow cytometry analyses. Results: Following administration of a therapeutic dose of tulathromycin, there were no changes in the lymphocyte subpopulations circulating in blood. In contrast, administration of ceftiofur at the recommended dose decreased the absolute number of CD3+, CD21+, CD4+CD8-, CD4-CD8+, and double positive CD4CD8 cells. Conclusion: Results from the study indicate that ceftiofur possesses the ability to modulate the immune system in healthy pigs by decreasing lymphocyte subpopulations circulating in blood.

    Background: This study was undertaken to evaluate demographics, clinical manifestations, laboratoryfi ndings and outcomes of children with inflammatory bowel disease (IBD) in Turkey. Methods: We analyzed the medical records of 127 children diagnosed with IBD (under 18 years old) between January 2004 and January 2012 in 8 pediatric gastroenterology centers. Results: Of the 127 patients, 90 (70.9%) suffered from ulcerative colitis (UC), 29 (22.8%) from Crohn's disease (CD), and 8 (6.3%) from IBD unclassified. The mean age of the 127 patients was 11.6±4.1 years, and 11.8% of the patients were below 5 years old. Of the patients, 49.6% were male, and males were more predominant in patients with CD than in those with UC (72.4%vs. 42.2%,P=0.008; a male/female ratio of 2.62 in CD, P=0.0016). Approximately one fifth of the patients had extra-intestinal manifestations and 13.3% of the patients had associated diseases. Extraintestinal manifestations and associated diseases were more common in early onset disease [P=0.017, odds ratio (OR)=4.02;P=0.03, OR=4.1]. Of the patients, 15% had normal laboratory parameters including anemia, high platelet count, hypoalbuminemia, hypoferritinemia, and high sedimentation rate. Area under receiver operation characteristics was used to predict pancolitis in patients with UC. The values of C-reactive protein, sedimentation rate and pediatric ulcerative colitis activity were 0.61 (P=0.06), 0.66 (P=0.01) and 0.76 (P=0.0001), respectively. Four (4.4%) patients with UC underwent colectomy, andfi nally two (1.5%, 95% confidence interval: 0-3.7%) patients died from primary disease or complications. Conclusions: IBD is an increasing clinical entity in Turkey. Features of IBD are similar to those in other populations, but prospective multicenter studies are needed to analyze the true incidence of IBD in Turkish children.

    Full Text Available Aim: This study aims to evaluate the views of the adult male population in Turkey concerning the use of drugs (Phosphodiesterase type 5 inhibitors and herbal products to increase sexual performance, and to assess the use and outcomes of these medications within the study site. Material and Method: This non-interventional, observational, sectional site study was conducted in 2012. Participants were randomly selected from 19 provinces of Turkey according to Eurostat and Nomenclature of territorial units for statistics (NUTS Level-2 by a proportional sampling method according to postal code lists. Men aged 18 years or older were included in this study as representatives of the male Turkish population. Of these, 410 men using at least one erectile dysfunction (ED product within the last year were interviewed face-to-face. Results: 98% of participants did not have ED. The rate of drug use for %u201Cincreasing sexual performance%u201D by those not reporting erection problems was 63%. Among this group of drugs, moderate to high satisfaction rates were observed for sildenafil and herbal products of 85% and 63% respectively. Women%u2019s awareness of their partners%u2019 drugs use was low at 25%. Satisfaction among women aware of their partners%u2019 drug use was 63%. Discussion: The prevalence of drug use, including PDE-5 inhibitors or herbal products, is high among Turkish men, who often do not inform their partners about their drug use. Given the high rate of satisfaction in cases where partners are informed, we believe that the positive psychosocial effects of these medications on partners could contribute to treatment planning.

    Full Text Available In the present study, we investigated the digenean parasites of Atlantic horse mackerel, Trachurus trachurus (L., 1758, in the Turkish Black Sea coast for the first time. Fish were collected throughout a year period from local fishermen in Sinop. A total of 256 fish specimens were weighed and measured, subsequently examined for parasites using conventional methods under an Olympus microscope (BX53 equipped with a digital camera (DP50. The examination included gills, pharynx, body cavity and visceral organs (stomach, intestine, liver, swim bladder and gonads. Parasites recovered were fixed and preserved using methods commonly applied. A total of five species including adults of Prodistomum polonii (Molin 1879 Bray and Gibson 1990, Ectenurus lepidus Looss, 1907, Monascus filiformis (Rudolphi, 1819 Looss, 1907, Lasiotocus typicus (Nicoll, 1912 and metacercaria of Stephanostomum cesticillum (Molin, 1858 Looss, 1899 were identified. Each parasite species were counted, their prevalence (% and mean intensity values were determined according to Bush et al. (1997. Kruskal-Wallis test (Non-parametric ANOVA was performed to find out the significant differences in the mean intensity values of the parasite for two length classes of fish as well as for the seasons. All the statistical tests were performed at the significance level of 5%. The calculated overall infection prevalence (% and mean intensity values were 48.8% and 3.78±0.34, respectively. This data is the first on the digenean parasite fauna of the Atlantic horse mackerel collected from the Turkish Black Sea coast. Lasiotocus typicus and Stephanostomum cesticillum are new parasite records for Turkey.

    The aim of this study was to estimate cancer incidence rate ratios for Turkish migrants in Hamburg, Germany. We used a name-based approach and identified 1346 cases with Turkish names (as a proxy of Turkish origin) among 140,249 cases of cancer registered in the cancer registry Hamburg during 1990-2005. To estimate the size of the denominator population, we applied the name-based approach to the population of Hamburg as well. The cancer incidence of specific cancer sites was compared between Turkish and non-Turkish cases using incidence rate ratios (IRR), stratified by gender and birth cohort. Our main findings are that cancer of the respiratory organs is diagnosed less frequent among Turkish men in older birth cohorts but with higher frequency in the younger birth cohorts. Malignant neoplasms of lymphoid, haematopoietic and related tissues are slightly higher in most male Turkish men birth cohorts, and even considerably higher for the birth cohort 1961 to <1971 (IRR=1.8). Among women, incidence rates for Turkish women are lower than for non-Turkish women for cancer of the respiratory system, skin cancer and cancer of genital organs. Also, breast cancer incidence rates of Turkish women are lower than for non-Turkish women, especially in older birth cohorts. Incidence rate ratios of neoplasms of lymphoid, haematopoietic and related tissues are low in the 1931 to <1941 cohort (IRR=0.71) but increase in younger birth cohorts. In conclusion, we found differences in cancer risks between cases with and without Turkish names for specific cancer sites. These results are consistent with the findings of studies from other countries.

    Full Text Available The present study aims to investigate the pronunciation problems of Turkish learners of English as a foreign language (Turkish EFL learners due to the orthography system of English. Orthography is a standardized system for using a particular writing system (script to write a particular language. It includes rules of spelling, and may also concern other elements of the written language such as punctuation and capitalization. It is clear that English is a non-phonetic and Turkish is a phonetic language, so it is very natural for the Turkish EFL learners to have some phonological problems in learning English. The author has done a contrastive study concerning three linguistic systems, i.e. consonants, vowels and syllable structures of English and Turkish to find the causes of the problems to be used in teaching English as a foreign language to Turks. The results of the study showed that the problems under discussion are caused by some differences between the orthography and the phonology of the two languages. As a result, English teachers, to be helpful, should focus on the differences and help the Turkish learners overcome the pronunciation problems. The author of the paper believes that an English teacher should be both aware of the differences and be able to teach them effectively to the Turkish EFL learners.

    Full Text Available This study focuses on teaching relative clauses (R.Cs in Turkish, a left-branching language, and discusses the relative difficulty of producing RCs in Turkish by English-speaking learners by investigating whether the production of subject relative clauses in Turkish is easier than that of the object relative clauses. It also offers suggestions as to how to help learners overcome these difficulties. Turkish and English belong to two different language families, Altaic and Inda-European respectively. This study lends further insight that Turkish does not have RCs similar to those found in Inda-European languages. Instead, in Turkish RCs comprise nominalized verbs and participles. The characteristics of Turkish are also explained such as its word order, agglutinating morphology, vowel and consonant harmony rules as well as case markers indicating grammatical relations between sentence constituents, which shed light to our understanding of RCs in Turkish. Data was collected through written and oral tasks from students enrolled in a military intensive Turkish language training program in the United States. Moreover, their performance was studied through classroom observations and one-on-one speaking activities.

    Previous studies of the primate cerebral cortex have shown that neurofilament protein is present in pyramidal neuron subpopulations displaying specific regional and laminar distribution patterns. In order to characterize further the neurochemical phenotype of the neurons furnishing feedforward and feedback pathways in the visual cortex of the macaque monkey, we performed an analysis of the distribution of neurofilament protein in corticocortical projection neurons in areas V1, V2, V3, V3A, V4, and MT. Injections of the retrogradely transported dyes Fast Blue and Diamidino Yellow were placed within areas V4 and MT, or in areas V1 and V2, in 14 adult rhesus monkeys, and the brains of these animals were processed for immunohistochemistry with an antibody to nonphosphorylated epitopes of the medium and heavy molecular weight subunits of the neurofilament protein. Overall, there was a higher proportion of neurons projecting from areas V1, V2, V3, and V3A to area MT that were neurofilament protein-immunoreactive (57-100%), than to area V4 (25-36%). In contrast, feedback projections from areas MT, V4, and V3 exhibited a more consistent proportion of neurofilament protein-containing neurons (70-80%), regardless of their target areas (V1 or V2). In addition, the vast majority of feedback neurons projecting to areas V1 and V2 were located in layers V and VI in areas V4 and MT, while they were observed in both supragranular and infragranular layers in area V3. The laminar distribution of feedforward projecting neurons was heterogeneous. In area V1, Meynert and layer IVB cells were found to project to area MT, while neurons projecting to area V4 were particularly dense in layer III within the foveal representation. In area V2, almost all neurons projecting to areas MT or V4 were located in layer III, whereas they were found in both layers II-III and V-VI in areas V3 and V3A. These results suggest that neurofilament protein identifies particular subpopulations of

    The annual incidence of malignant melanoma is estimated at 10-12 per 100000 inhabitants in countries of Central Europe and the US, with more recent estimates showing a dramatic upward trend. Taurolidine (Carter/Wallace, Cranberry, NJ) is a novel, potentially effective, antitumor chemotherapeutic agent. We hypothesized that Taurolidine could inhibit the growth, induce apoptosis, affect the cell cycle and change morphology of melanoma cells. We expected this process to be different in adherent and floating subpopulations that may be reflective of solid tumors and their metastases. Analysis of MNT-1 human and B16F10 murine melanoma cells showed that at 72 h the IC(50) of Taurolidine was 25.4+/-3.3 microM for MNT-1 human melanoma cells and 30.9+/-3.6 microM for B16F10 murine melanoma cells. Taurolidine induced DNA fragmentation of melanoma cells in a dose-dependent manner. Taurolidine (75 and 100 microM) induced 52-97% Annexin-V binding (apoptosis), respectively. Evaluation of cell cycle after 72 h exposure to Taurolidine (0-100 microM) revealed that the percentage of melanoma cells in S phase increased from 27 to 40% in the adherent subpopulation and from 33 to 49% in the floating subpopulation. Phase contrast microscopy revealed a marked swelling of melanoma cells and decreasing cell numbers in adherent subpopulation starting at 24 h with 25 microM Taurolidine. Shrinkage of cells dominated at 75-100 microM Taurolidine. Using Cytospin assay in the floating population, we observed swelling of melanoma cells induced by 25-100 micro Taurolidine and appearance of giant (multinuclear) forms resulting from exposure to 75-100 micro Taurolidine. Some floating cells with normal morphology were observed with low concentrations of Taurolidine (0-25 microM). These data show that effects of Taurolidine may be different in adherent and floating subpopulations of melanoma cells. More importantly, floating subpopulations that may contain some viable melanoma cells, may be reflective

    Full Text Available This study investigated the misuse of Information and Communication Technologies (ICTs among children and youth. The data source was newspaper reports obtained from three Turkish daily newspapers, between January 2006 and December 2012. In that seven years period, a total of 66 ICT misuse incidents were reported in the selected newspapers. Document analysis was performed on the newspaper reports. Themes and codes were entered as variables to manage the data quantitatively. Results revealed that ICT misuse was most commonly conducted through cell phones, social networking sites, instant messaging and web pages. Young people’s involvement of ICT misuse had three forms; from young perpetrator/s to the young victim/s, from young perpetrator/s to adult victim/s and from adult perpetrator/s to young victim/s. ICTs were commonly misused for sexual abuse, insulting or taking revenge. While perpetrators were mostly males whose ages ranged between 14 and 52, a great majority of ICT misuse victims were females, with an age range from 8 to 46. Negative psychological and physiological impacts were reported by the victims.

    On the island of Cyprus, believed to be the birthplace of Aphrodite, the Muslim minority (settled there following the Ottoman conquest of the island in 1571) and Orthodox Christians (the native majority) lived together in peace for hundreds of years. However, as a result of ethnic conflict in the late 1950s, the Muslim Cypriot Turks established their own political state in the north of the island in 1974, and Cyprus was divided into northern Turkish and southern Greek sections. This paper attempts to examine historical, religious, cultural and psychological aspects of the relationship between these two large groups, prior to recent conflicts, by studying fairy tales told by Turkish Cypriots about a hundred years ago. It is hoped that this paper will encourage similar studies of other communities where different large-group identities live side by side, and that such studies may support their peaceful co-existence.

    Full Text Available Being primarily responsible of conducting logistical and emotional work of child-rearing, mothers have agency in formation of the child’s future identity, cultural values and dispositions, and serve as role models, sources of social pressure, and interpersonal support. This article aims to discover discourses of motherhood of Turkish mothers, especially educated and middle class, who have children dependent on their consumption decisions and how their discourses figure in their consumption practices of products, such as food and clothing, which they buy on behalf of their children. Discursive and consumption practices of Turkish mothers who are participating in selected virtual communities are analyzed by means of qualitative research methods. Main discourses that can be observed in their told consumption practices appeared to be the “good mothering” and “motherhood as personal achievement”. Backgrounding and absent discourses are also discussed.

    2007-10-01

    In this study, sexual attitudes and behaviors of Turkish university students were explored by taking many influential agents both at the distal and the proximal levels into consideration. A total of 563 students from three universities located in three cities completed a questionnaire that assessed their virginity status, first intercourse, sexual permissiveness, pornography usage, endorsement of traditional sexual double standards, and the perception of parental attitudes about sexuality. The results showed that women and students from rural areas were more traditional and conservative in their attitudes and behaviors regarding sexuality. The perception of maternal restriction about sexuality was related to sexual conservatism, negative affective reaction at first coitus, and endorsing traditional sexual double standards. The results are discussed in terms of various degrees of influences originating from proximal and distal variables in the Turkish context.

    Full Text Available Background: Posttraumatic growth (PTG is conceptualized as a positive transformation resulting from coping with and processing traumatic life events. This study examined the contributory roles of personality traits, posttraumatic stress (PTS severity and their interactions on PTG and its domains, as assessed with the Posttraumatic Growth Inventory Turkish form (PTGI-T. The study also examined the differences in PTG domains between survivors of accidents, natural disasters and unexpected loss of a loved one. Methods: The Basic Personality Traits Inventory, Posttraumatic Diagnostic Scale, and PTGI-T were administered to a large stratified cluster community sample of 969 Turkish adults in their home settings. Results: The results showed that conscientiousness, agreeableness, and openness to experience significantly related to the total PTG and most of the domains. The effects of extraversion, neuroticism and openness to experience were moderated by the PTS severity for some domains. PTG in relating to others and appreciation of life domains was lower for the bereaved group. Conclusion: Further research should examine the mediating role of coping between personality and PTG using a longitudinal design.

    In contrast to planktonic cultures of the human fungal pathogen Candida albicans, C. albicans biofilms can contain a persister subpopulation that is tolerant to high concentrations of currently used antifungals. In this chapter, the method to determine the persister fraction in a C. albicans biofilm treated with an antifungal compound is described. To this end, a mature biofilm is developed and subsequently treated with a concentration series of the antifungal compound of interest. Upon incubation, the fraction of surviving biofilm cells is determined by plating and plotted versus the used concentrations of the antifungal compound. If a persister subpopulation in the biofilm is present, the dose-dependent killing of the biofilm cells results in a biphasic killing pattern.

    Brain networks can support learning by promoting acquisition of task-relevant information or by adhering to validated rules, but the mechanisms involved are poorly understood. Upon learning, local inhibitory parvalbumin (PV)-expressing Basket cell networks can switch to opposite configurations that either favor or interfere with further learning, but how this opposite plasticity is induced and relates to distinct learning requirements has remained unclear. Here, we show that PV Basket cells consist of hitherto unrecognized subpopulations, with distinct schedules of neurogenesis, input connectivities, output target neurons, and roles in learning. Plasticity of hippocampal early-born PV neurons was recruited in rule consolidation, whereas plasticity of late-born PV neurons was recruited in new information acquisition. This involved regulation of early-born neuron plasticity specifically through excitation, and of late-born neuron plasticity specifically through inhibition. Therefore, opposite learning requirements are implemented by distinct local networks involving PV Basket cell subpopulations specifically regulated through inhibition or excitation.

    Although national colorectal cancer (CRC) incidence rates have steadily decreased, the rate for New Mexico Hispanics has been increasing, and screening rates are low. We conducted an exploratory qualitative study to determine barriers to CRC screening for New Mexico Hispanics. We found that machismo served as a dynamic influence on men's health-seeking behaviors; however, it was conceptualized differently by two distinct Hispanic subpopulations, and therefore appeared to play a different role in shaping their screening attitudes and behaviors. Machismo emerged as more of an influence for Mexican men, who expressed concern over colonoscopies being potentially transformative and/or stigmatizing, but was not as salient for Hispanos, who viewed the colonoscopy as "strictly medical," and were more concerned with discomfort and pain. Findings from the study highlight the importance of identifying varying characteristics among subpopulations to better understand screening barriers and provide optimal CRC screening counseling in primary care settings.

    Most globular clusters (GCs) are now known to host multiple stellar populations with different light element abundances. Here we use narrow-band photometry and low-resolution spectroscopy for NGC 362 and NGC 6723 to investigate their chemical properties and radial distributions of subpopulations. We confirm that NGC 362 and NGC 6723 are among the GCs with multiple populations showing bimodal CN distribution and CN-CH anti-correlation without a significant spread in calcium abundance. These two GCs show more centrally concentrated CN-weak earlier generation stars compared to the later generation CN-strong stars. These trends are reversed with respect to those found in previous studies for many other GCs. Our findings, therefore, seem contradictory to the current scenario for the formation of multiple stellar populations, but mass segregation acting on the two subpopulations might be a possible solution to explain this reversed radial trend.

    The current status of marine poisonous fish species ranging in the Aegean Sea coastline in Turkey were introduced. Turkey is a peninsula surrounded by seas with different ecological features on three sides. The total length of shoreline is 8 333 km including the islands. The total number of fish species in Turkish seas is 512, of which 449 live in the Aegean Sea followed by the Mediterranean Sea (441 species), the Marmara Sea (257 species) and the Black Sea (154species). On the Aegean Sea coasts, the richest sea regarding fish diversity, the number of poisonous fish species is also high. This mini-review revealed 51 poisonous fish species belonging to 14 families in the Turkish Aegean Sea. On the Aegean Sea coasts poisonous fish species can be categorized into three groups: (i) Fish that contain venomous spines on the tail or on the operculum (ii) Fish that carry poisonous bite and (iii) Fish having poisonous flesh or liver. Poisoning fish that contain venomous spines on the tail or on the operculum mostly are dangerous because of their poisonous thorns whereas the passive poisonous fish species poison when they are eaten. These toxins can cause morbidity and rarely, mortality in humans. Apart from these, swallowing the blood of species such as European eelAnguilla anguillaand European congerConger congermight also cause poisoning. Besides, as there has been an invasion of puffer fish especially on the Turkish Mediterranean and Aegean coasts in recent years, there is a danger in question. Thus, it is very important to particularly draw attention to these fish on the Turkish coasts.

    Full Text Available “The 21st century is a period in which Turkey is going through deep changes not only in domestic policies, economic and social issues but also in foreign policies and diplomacy. The opening-up of Turkish people to the world in the 1990ies paved the way to their interaction with other countries which, in turn, played a major role in the transformation of the country. In this period, the parallel diplomacy practiced on a one-to-one basis by Turkish educational institutions, local governments and various NGOs through activities ranging from cultural events to humanitarian aid, has been the invisible power of Turkish foreign policy. As a country which has a universal narrative story of its own to tell the world, Turkey’s way to expressing itself in a correct and efficient way, goes through the development of individual rights and freedoms, the granting of a sense of belonging to its citizens which they will be proud of as well as the support of cultural diplomacy carried out by NGOs. Thus, a strategy to be developed by leading NGOs which are the main actors of cultural diplomacy, and providing them the resources they need, will not only strengthen the democratic structure of the country. Above all, through such a strategy, Turkey’s soft power which plays a leading role in the practice of cultural diplomacy on a global scale will become all the more so efficient and perceptible. Taking into consideration the changes currently occurring in the world, this article dealing with cultural diplomacy aims at shedding a light on the evolution which Turkish diplomacy is going through in terms of its enforcing institutions and practice.

    2008-06-01

    Full Text Available Abstract Background Leishmania (Leishmania major, one of the agents causing cutaneous leishmaniasis (CL in humans, is widely distributed in the Old World where different species of wild rodent and phlebotomine sand fly serve as animal reservoir hosts and vectors, respectively. Despite this, strains of L. (L. major isolated from many different sources over many years have proved to be relatively uniform. To investigate the population structure of the species highly polymorphic microsatellite markers were employed for greater discrimination among it's otherwise closely related strains, an approach applied successfully to other species of Leishmania. Results Multilocus Microsatellite Typing (MLMT based on 10 different microsatellite markers was applied to 106 strains of L. (L. major from different regions where it is endemic. On applying a Bayesian model-based approach, three main populations were identified, corresponding to three separate geographical regions: Central Asia (CA; the Middle East (ME; and Africa (AF. This was congruent with phylogenetic reconstructions based on genetic distances. Re-analysis separated each of the populations into two sub-populations. The two African sub-populations did not correlate well with strains' geographical origin. Strains falling into the sub-populations CA and ME did mostly group according to their place of isolation although some anomalies were seen, probably, owing to human migration. Conclusion The model- and distance-based analyses of the microsatellite data exposed three main populations of L. (L. major, Central Asia, the Middle East and Africa, each of which separated into two sub-populations. This probably correlates with the different species of rodent host.

  11. Characterization of cell subpopulations expressing progenitor cell markers in porcine cardiac valves.

    Directory of Open Access Journals (Sweden)

    Huan Wang

    Full Text Available Valvular interstitial cells (VICs are the main population of cells found in cardiac valves. These resident fibroblastic cells play important roles in maintaining proper valve function, and their dysregulation has been linked to disease progression in humans. Despite the critical functions of VICs, their cellular composition is still not well defined for humans and other mammals. Given the limited availability of healthy human valves and the similarity in valve structure and function between humans and pigs, we characterized porcine VICs (pVICs based on expression of cell surface proteins and sorted a specific subpopulation of pVICs to study its functions. We found that small percentages of pVICs express the progenitor cell markers ABCG2 (~5%, NG2 (~5% or SSEA-4 (~7%, whereas another subpopulation (~5% expresses OB-CDH, a type of cadherin expressed by myofibroblasts or osteo-progenitors. pVICs isolated from either aortic or pulmonary valves express most of these protein markers at similar levels. Interestingly, OB-CDH, NG2 and SSEA-4 all label distinct valvular subpopulations relative to each other; however, NG2 and ABCG2 are co-expressed in the same cells. ABCG2(+ cells were further characterized and found to deposit more calcified matrix than ABCG2(- cells upon osteogenic induction, suggesting that they may be involved in the development of osteogenic VICs during valve pathology. Cell profiling based on flow cytometry and functional studies with sorted primary cells provide not only new and quantitative information about the cellular composition of porcine cardiac valves, but also contribute to our understanding of how a subpopulation of valvular cells (ABCG2(+ cells may participate in tissue repair and disease progression.

    2011-09-15

    Each of the three Th2 cytokine genes, IL-4, IL-5, and IL-13, has different functions. We hypothesized that Th2 heterogeneity could yield Th2 subpopulations with different cytokine expression and effector functions. Using multiple approaches, we demonstrate that human Th2 cells are composed of two major subpopulations: a minority IL-5(+) (IL-5(+), IL-4(+), IL-13(+)) and majority IL-5(-) Th2 (IL-5(-), IL-4(+), IL-13(+)) population. IL-5(+) Th2 cells comprised only 20% of all Th2 cells. Serial rounds of in vitro differentiation initially yielded IL-5(-) Th2, but required multiple rounds of differentiation to generate IL-5(+) Th2 cells. IL-5(+) Th2 cells expressed less CD27 and greater programmed cell death-1 than IL-5(-) Th2 cells, consistent with their being more highly differentiated, Ag-exposed memory cells. IL-5(+) Th2 cells expressed greater IL-4, IL-13, and GATA-3 relative to IL-5(-) Th2 cells. GATA-3 and H3K4me(3) binding to the IL5 promoter (IL5p) was greater in IL-5(+) relative to IL-5(-) Th2 cells, whereas there was no difference in their binding to the IL4p and IL13p. Conversely, H3K27me(3) binding to the IL5p was greater in IL-5(-) Th2 cells. These findings demonstrate Th2 lineage heterogeneity, in which the IL5 gene is regulated in a hierarchical manner relative to other Th2 genes. IL-5(+) Th2 cells are phenotypically distinct and have epigenetic changes consistent with greater IL5p accessibility. Recurrent antigenic exposure preferentially drives the differentiation of IL-5(+) Th2 cells. These results demonstrate that IL-5(+) and IL-5(-) Th2 cells, respectively, represent more and less highly differentiated Th2 cell subpopulations. Such Th2 subpopulations may differentially contribute to Th2-driven pathology.

    Full Text Available New Turkish Program has been based upon activities that will provide participation of students to the educational process. Story formation with drama which is one of the most suitable activities to actualize requirements of the Turkish education is to animate improvised or proverbial stories using drama techniques. What has been meant with the expression of story formation in drama studies is to accommodate story genre into animation of other genres including texts based upon events rather than dramatization of the genre’s itself. Through the animation of the story, the student will have the opportunity of examining, analyzing and solving the problems related to real life. While concepts such as hero, target, obstacle /event have been the primary elements of story formation, concepts such as speech line and metaxis are the secondary elements. There can be provided the acquisition of four basic language abilities to be actualized, association of linguistic concepts with daily life and exposure of a hidden ability into the light through the stories formed with drama in Turkish lessons. This study has been carried out using the scanning model and relevant researches within the bounds of the subject have been benefited.

    2013-12-01

    Full Text Available Ecological variation of the selected subpopulations of Iris sibirica L. were studied in the years 2011-2012, in the abandoned patches of Molinietum caeruleae dominated by small meadow species (Patch I, macroforbs (Patch II, largetussock grasses (Patch III, shrubs (Patch IV, as well as shrubs and trees (Patch V. The abundance of subpopulations and dimensions of aggregations of ramet clusters increased gradually from Patch I to Patch IV and subsequently declined in Patch V. During the whole study period, all subpopulations showed signs of senility due to the absence of individuals in prereproductive stages. The share of generative ramet clusters diminished, while contribution of senile and fragmentised ramet clusters increased substantially in consecutive patches. The dimensions of ramet clusters increased significantly in successive plots and years. The number and height of generative stems and production of flowers and fruits did not show the temporal variability. The abundance of generative stems was considerably lower in the plots dominated by small meadow species, than in the sites dominated by large-tussock grasses, shrubs or overgrown shrubs and trees. Both the height of flowering stems and production of flowers and fruits increased gradually from Patch I, via Patches II, III and IV, to Patch V. The augmentation of flower production might contribute to better visibility of inflorescences for pollinators, whereas an increase in the production of fruits may increase the chances for successful seed dispersal to new sites.

    Cellular heterogeneity is inherent in most human tissues, making the investigation of specific cell types challenging. Here, we describe a novel, fixation/intracellular target-based sorting and protein extraction method to provide accurate protein characterization for cell subpopulations. Validation and feasibility tests were conducted using homogeneous, neural cell lines and heterogeneous, rat brain cells, respectively. Intracellular proteins of interest were labeled with fluorescent antibodies for fluorescence-activated cell sorting. Reproducible protein extraction from fresh and fixed samples required lysis buffer with high concentrations of Tris-HCl and sodium dodecyl sulfate as well as exposure to high heat. No deterioration in protein amount or quality was observed for fixed, sorted samples. For the feasibility experiment, a primary rat subpopulation of neuronal cells was selected for based on high, intracellular β-III tubulin signal. These cells showed distinct protein expression differences from the unsorted population for specific (phosphorylated tau) and non-specific (total tau) protein targets. Our approach allows for determining more accurate protein profiles directly from cell types of interest and provides a platform technology in which any cell subpopulation can be biochemically investigated.

  19. Versatile action of picomolar gradients of progesterone on different sperm subpopulations.

    Directory of Open Access Journals (Sweden)

    Diego Rafael Uñates

    Full Text Available High step concentrations of progesterone may stimulate various sperm physiological processes, such as priming and the acrosome reaction. However, approaching the egg, spermatozoa face increasing concentrations of the hormone, as it is secreted by the cumulus cells and then passively diffuses along the cumulus matrix and beyond. In this context, several questions arise: are spermatozoa sensitive to the steroid gradients as they undergo priming and the acrosome reaction? If so, what are the functional gradual concentrations of progesterone? Do spermatozoa in different physiological states respond differentially to steroid gradients? To answer these questions, spermatozoa were confronted with progesterone gradients generated by different hormone concentrations (1 pM to 100 µM. Brief exposure to a 10 pM progesterone gradient stimulated priming for the acrosome reaction in one sperm subpopulation, and simultaneously induced the acrosome reaction in a different sperm subpopulation. This effect was not observed in non-capacitated cells or when progesterone was homogeneously distributed. The results suggest a versatile role of the gradual distribution of very low doses of progesterone, which selectively stimulate the priming and the acrosome reaction in different sperm subpopulations.

  20. Tactile perception: do distinct subpopulations explain differences in mislocalization rates of stimuli across fingertips?

    In a previous study we were able to demonstrate that the Cutaneous Rabbit Effect (CRE) could be induced across fingertips using a form of the reduced rabbit paradigm and electrotactile stimuli. The CRE, as used here, is an illusory phenomenon where two stimuli are rapidly at a site and then a stimulus is presented to a nearby site. The perception of the second of the stimuli is not at its presented location but at a site between the first and last stimuli. In this experiment, though the overall population did perceive the mislocalized stimuli as the CRE would predict, some subjects were very infrequently observed to mislocalize stimuli due to the CRE or other effects. Here we further examine this phenomena, attempting to identify whether a subpopulation exists that rarely mislocalizes stimuli on their fingertips. To test for this subpopulation, we reexamined the collected data from the previously published experiment and other unpublished data relating to that study. By examining these data for rates of mislocalization utilizing our previous metric we identified that there is a perceptual subpopulation that very infrequently misidentifies the location of a fingertip stimulus.

  1. Dynamics between cancer cell subpopulations reveals a model coordinating with both hierarchical and stochastic concepts.

    Directory of Open Access Journals (Sweden)

    Weikang Wang

    Full Text Available Tumors are often heterogeneous in which tumor cells of different phenotypes have distinct properties. For scientific and clinical interests, it is of fundamental importance to understand their properties and the dynamic variations among different phenotypes, specifically under radio- and/or chemo-therapy. Currently there are two controversial models describing tumor heterogeneity, the cancer stem cell (CSC model and the stochastic model. To clarify the controversy, we measured probabilities of different division types and transitions of cells via in situ immunofluorescence. Based on the experiment data, we constructed a model that combines the CSC with the stochastic concepts, showing the existence of both distinctive CSC subpopulations and the stochastic transitions from NSCCs to CSCs. The results showed that the dynamic variations between CSCs and non-stem cancer cells (NSCCs can be simulated with the model. Further studies also showed that the model can be used to describe the dynamics of the two subpopulations after radiation treatment. More importantly, analysis demonstrated that the experimental detectable equilibrium CSC proportion can be achieved only when the stochastic transitions from NSCCs to CSCs occur, indicating that tumor heterogeneity may exist in a model coordinating with both the CSC and the stochastic concepts. The mathematic model based on experimental parameters may contribute to a better understanding of the tumor heterogeneity, and provide references on the dynamics of CSC subpopulation during radiotherapy.

    Full Text Available Proverbs give instructions on how to behave in everyday life. They reflect common experiences of a society. Beliefs, thoughts and cultures of the past are crtically evaluated by them. Those proverbs that include reflections of the past generations on business life may provide today’s business people for guidance. Considering this fact, it is possible to get information about “business culture” by studying proverbs. National business systems embodying the values of “exclusive business cultures” of a society form the economic organizational structue of that society. This articles aims at identifying basic characteristics of Turkish business system through studying proverbs. Besides, it attemps to propose a working model for Turkish business system. In connection with this, it is observed that strategic planning and discipline are important in business processes, common reason is taken into account in business operations, and productivity is determined by methods production and procurement processes.

  5. The adaptation study of oral communication strategy inventory into Turkish

    2013-10-01

    Full Text Available Individuals use a variety of strategies in the course of speaking which can be identified via measurement tools. In the literature, strategy inventories are regarded as the most commonly used measurement tools. However, most of the strategy inventories lack the reliability and validity studies. Furthermore, most of them represent strategies that the learner could use throughout the language learning process and they are not directly relevant to the skill of speaking. Moreover, in the literature, most of the studies carried out on speaking strategies are based on the inventories developed for learners learning English as a second language. With respect to other measurement tools, Oral Communication Strategy Inventory (OCSI developed by Nakatani (2006 for Japanese learning English as a foreign language had a clear factor structure and it seemed less problematic. Thus, the purpose of this study was to adapt OCSI into Turkish. Our concern in the adaptation study of OCSI is to investigate whether oral communication strategies classified in OCSI developed by Nakatani (2006 would also measure Turkish EFL students’ speaking strategy use. Within the scope of adaptation study, the inventory was translated to Turkish and evaluated with the method of back translation. The equivalence between English form and Turkish form, construct validity and internal consistency were examined. The research was conducted with 808 students studying English as a foreign language at ELT departments of three different universities and Anatolian High schools. Based on the findings concerning the reliability and validity studies, it can be concluded that the classification of the original form of OCSI differs from the adapted version to some extent in that the Turkish form is made up of seven factors in contrast to the original inventory consisting of eight factors. Non verbal strategies which existed in Nakatani’s original inventory did not appear in the adaptation form

    Full Text Available Military services have many contributions to the development of societies all over the world. In war and peace and also in emergencies, they continue to serve to their workers and civilian people. It is known that, Turkish Military Forces as one of the largest military forces in the world have the ability to provide health-care services. Firstly, in the Crimean War between 1853 and 1856, Gulhane Military Hospital in Istanbul began to produce medicine and bandages which are needs of the Turkish Army. Afterwards, in the First World War, the production of such needs continued in a storage Beylerbeyi Palace and in Konya. In 1928, these institutions were combined in Ankara the capital city of the Turkish Republic. The production continues in the pharmaceutical factory under the Ministry of National Defense. The historical evaluation of the military drug factory and its contribution to health services were examined in this study. [TAF Prev Med Bull 2015; 14(2.000: 171-176

    1983-03-01

    This research has investigated the effects of combined modality treatment on the survival responses of two tumour subpopulations obtained from a heterogeneous human colon adenocarcinoma. An isobologram analysis of the clonogenic survival responses of the two tumour subpopulations showed that the clone A responses were within the envelope of additivity for either sequence of application. In contrast, the responses of the clone D tumour subpopulation exhibited a supra-additive response to the combined treatments with the sequence of heat followed by X-irradiation being somewhat more effective than the sequence of X-irradiation followed by heat. These data indicate that the responses of tumour subpopulations obtained from heterogeneous solid tumours to combined modality treatments may vary in an, at present, unpredictable manner.

    We assessed taxonomic relationships among Turkish water frogs through estimation of phylogenetic relationships among 62 adult specimens from 44 distinct populations inhabiting seven main geographical regions of Turkey using 2897 bp sequences of the mitochondrial Cytb, 12S rRNA and 16S rRNA genes with equally-weighted parsimony, likelihood, and Bayesian methods of inference. Monophyletic clade (Clade A) of the northwesternmost (Thrace) samples is identified as Pelophylax ridibundus. The other clade (Clade B) consisted of two monophyletic subclades. One of these contains specimens from southernmost populations that are regarded as an unnamed species. The other subclade consists of two lineages, of which one corresponds to P. caralitanus and another to P. bedriagae. Taxonomic relationships of these two species are discussed and recognition of P. caralitanus as a subspecies of P. bedriagae is proposed.

    Full Text Available The present studies aim to compare the cultural values promoted by the French educational system and the Turkish families living in France to their youngsters. Because of their collectivist background Turkish immigrants may convey less individualistic values to their children compared to French parents and teachers. However, Turkish students may become more individualistic as they are socialized in the school system. In study 1 (N = 119, French school teachers, French parents, and Turkish-origin parents had to resolve six dilemmas by choosing either an individualistic or a collectivistic response-option. As expected, French teachers emphasized individualism more than Turkish parents, but not more than French parents. In Study 2 (N = 159, similar dilemmas were presented to French and Turkish-origin pupils. In elementary school, Turkish children were less individualistic than French-born children, but this gap was reduced in high school.

    Full Text Available Study objectives were to compare the numbers of lymphocytes and lymphocyte subpopulations in induced sputum from asthmatic patients and from healthy subjects, and to determine the effect of inhaled anti-asthmatic steroid therapy on these cell numbers. Hypertonic saline inhalation was used to non-invasively induce sputum samples in 34 patients with bronchial asthma and 21 healthy subjects. The sputum samples were reduced with dithioerythritol and absolute numbers of lymphocytes and lymphocyte subpopulations were assessed by direct immunofluorescence and flow cytometry. To assess the effect of beclomethasone dipropionate (BDP on induced sputum, numbers of lymphocytes and lymphocyte subpopulations in sputum also were evaluated after 4 weeks of BDP inhalation treatment in seven asthmatic patients. An adequate sample was obtained in 85.3% of patients with asthma and in 79.2% of the healthy subjects. Induced sputum from patients with asthma had increased numbers of lymphocytes (P = 0.009; CD4+ cells (P = 0.044; CD4+ cells-bearing interleukin-2 receptor (CD25; P = 0.016; and CD4+ cells bearing human histocompatibility leukocyte antigen (HLA-DR (P = 0.033. CD8+ cells were not increased in asthmatic patients. In patients treated with inhaled steroids, numbers of lymphocytes, CD4+ cells, CD25-bearing CD4+ cells and HLA-DR-bearing CD4+ cells in sputum decreased from pretreatment numbers (P = 0.016, 0.002, 0.003 and 0.002, respectively. Analysis of lymphocytes in induced sputum by flow cytometry is useful in assessing bronchial inflammation, and activated CD4+ lymphocytes may play a key role in the pathogenesis of airway inflammation in bronchial asthma.

    Full Text Available Pivotal challenges in industrial biotechnology are the identification and overcoming of cell-to-cell heterogeneity in microbial processes. While the development of subpopulations of isogenic cells in bioprocesses is well described (intra-population variability, a possible variability between genetically identical cultures growing under macroscopically identical conditions (clonal variability is not. A high such clonal variability has been found for the recombinant expression of the styrene monooxygenase genes styAB from Pseudomonas taiwanensis VLB120 in solvent-tolerant Pseudomonas putida DOT-T1E using the alk-regulatory system from P. putida GPo1. In this study, the oxygenase subunit StyA fused to eGFP was used as readout tool to characterize the population structure in P. putida DOT-T1E regarding recombinant protein content. Flow cytometric analyses revealed that in individual cultures, at least two subpopulations with highly differing recombinant StyA-eGFP protein contents appeared (intra-population variability. Interestingly, subpopulation sizes varied from culture-to-culture correlating with the specific styrene epoxidation activity of cells derived from respective cultures (clonal variability. In addition, flow cytometric cell sorting coupled to plasmid copy number (PCN determination revealed that detected clonal variations cannot be correlated to the PCN, but depend on the combination of the regulatory system and the host strain employed. This is, to the best of our knowledge, the first work reporting that intra-population variability (with differing protein contents in the presented case study causes clonal variability of genetically identical cultures. Respective impacts on bioprocess reliability and performance and strategies to overcome respective reliability issues are discussed.

    Comparison of behavioural similarities between subpopulations of species that have been isolated for a long time is important for understanding the general ecology of species that are under pressure from large-scale changes in habitats. Narwhals (Monodon monoceros) east and west of Greenland...... are examples of separated populations that, in different ocean parts, will be coping with similar anthropogenic and climate-driven habitat alterations. To study this, 28 narwhals from the Scoresby Sound fjord system were tracked by satellite in 2010-2013. The average duration of contact with the whales was 124...

    The responses of two heterogeneous human cancer cell lines and their derivative clones to graded single doses of X-rays were examined in vitro. One system consisted of the human colon carcinoma line DLD-1 and two subpopulations (clones A and D). The second system consisted of the human lung carcinoma line (LX1) and four subpopulations (LX1-1, LX1-2, LX1-3, and LX1-9). These subpopulations have previously been shown to be markedly heterogeneous in terms of such characteristics as karyotype, morphology, drug sensitivity, tumorigenicity, and expression of membrane glycoproteins (such as carcinoembryonic antigen and tumor colonic mucoprotein antigen). Exponentially growing cultures were irradiated with graded single doses of 100-kVp X-rays. Survival was assessed using colony formation as the end point, and responses from multiple experiments were fitted to the single-hit, multitarget equation of cell survival. Values for the mean lethal dose (D0, grays), quasithreshold dose (Dq, grays), and extrapolation number (n) were obtained. For the human colon adenocarcinoma system, these values for the three tumor lines were: DLD-1, 0.95, 2.34, and 11.7; clone A, 1.06, 2.23 and 8.20; and clone D, 1.08, 1.89, and 5.80. For the human lung carcinoma system, these values for the five sublines were: LX1, 1.14, 0.19, and 1.20; LX1-1, 0.96, 2.06, and 8.54; LX1-2, 0.98, 0.88, and 2.48; LX1-3, 0.68, 2.05, and 20.3; and LX1-9, 1.12, 0.00, and 1.00. These two human tumor systems therefore exhibit variability in their intrinsic sensitivity to X-irradiation. The data indicate that failure of some human carcinomas to respond to physical treatment modalities can be due to preexisting resistant subpopulations.

    The repair of sublethal radiation damage in two asynchronously growing tumour cell subpopulations (clones A and D) obtained from a single human adenocarcinoma biopsy specimen has been studied. The survival data found after generation of complete survival curves from split dose experiments in which exposures were separated by 3, 6, 12, or 24 h were examined. It was found that the method of performing irradiations (e.g., suspension cultures versus monolayer cultures) affected the shape of the single dose response curves, and as a result the interpretation of the amount of sublethal damage repair occurring after split dose irradiation.

    Responses of a heterogeneous human colon adenocarcinoma model tumor system to in vitro hyperthermic treatment at various temperatures have been studied. This model tumor system consists of an original tumor line (DLD-1) obtained from surgical biopsy, and two derivative subpopulations termed clones A and D. These 3 tumor cell populations differ in many properties, including karyotype and DNA content, production of specific antigens, and sensitivities to other cytotoxic agents such as chemotherapeutic drugs and X-irradiation. In these experiments, exponentially growing tumor cells were exposed to hyperthermia (42.2, 42.5, 43.0, 44.0, or 45.0 degrees) for graded time periods. A single-hit, multitarget equation was used to express the dependence of survival on time at a given temperature, and values for extrapolation numbers, quasi-threshold time (min), and T0 (mean lethal time; min) were obtained for the initial regions of survival. At the lower temperatures of 42.2 and 42.5 degrees, biphasic survival curves were obtained for all three tumor lines and, as a consequence, a second mean lethal time (T0,f) was also determined for the final thermal-resistant portion of the survival curves. Using the T0 values as an index of relative resistance, values at 42.2 and 42.5 degrees indicated that, in this temperature region, the parent (DLD-1) line was the most sensitive, the clone A line showed intermediate sensitivity, and the clone D line was the most resistant. In the thermally resistant portion of the survival curve, T0 values indicated that the clone A subpopulation was the most sensitive, the DLD-1 line showed intermediate sensitivity, and the clone D tumor subpopulation remained the most resistant. At the higher temperatures of 43, 44, and 45 degrees, in which thermotolerance is not observed during heat treatment, values for T0 indicated the parent (DLD-1) tumor line was still the most sensitive tumor line, and the clone A and clone D lines showed approximately equal

    Full Text Available Previous research indicates that people with higher levels of self-actualization have lower death anxiety and that negative emotional states are related to death anxiety. The aim of this study is to investigate the relationship between death anxiety and self-actualization, depression, and trait anxiety. A Turkish sample of 116 undergraduates and adults completed Templer’s Death Anxiety Scale, Personal Orientation Inventory, Beck Depression Inventory, and State-Trait Anxiety Inventory’s Trait Anxiety Form. Hierarchical regression analysis showed that the only significant predictors of death anxiety were trait anxiety and gender. The correlation between death anxiety and self - actualization was found to be negative and statistically significant (p < .001. Women had significantly higher death anxiety compared to men; whereas death anxiety mean scores did not show significant differences by age group and the belief in afterlife. In conclusion, this study supports the assumptions of the existential school regarding the association between death anxiety and self-actualization.

    Thirteen Turkish patients with hereditary fructose intolerance (HFI) were screened for the three common mutations, A149P, A174D and N334K, in the aldolase B gene that have been detected frequently in European population. We found that nine of the patients carry the A149P mutation in both alleles, which corresponds to a frequency of about 55%. Single-strand conformation analysis of all coding exons of the gene was also performed to detect unknown mutations in four patients not carrying the three common mutations. No aberrant migration patterns were observed in these patients.

    The high number of Turkish immigrants in the German state North-Rhine Westphalia (NRW) compelled us to look for HIV-infected patients with Turkish nationality. In the AREVIR database, we found 127 (107 men, 20 women) Turkish HIV patients living in NRW. In order to investigate transmission clusters and their correlation to gender, nationality and self-reported transmission mode, a phylogenetic analysis including pol gene sequences was performed. Subtype distribution and the number of HIV drug resistance mutations in the Turkish patient group were found to be similar to the proportion in the non-Turkish patients. Great differences were observed in self-reported mode of transmission in the heterosexual Turkish male subgroup. Neighbour-joining tree of pol gene sequences gave indication that 59% of these reported heterosexual transmissions cluster with those of men having sex with men in the database. This is the first study analysing HIV type distribution, drug resistance mutations and transmission mode in a Turkish immigrant population.

    Different languages map semantic elements of spatial relations onto different lexical and syntactic units. These crosslinguistic differences raise important questions for language development in terms of how this variation is learned by children. We investigated how Turkish-, English-, and Japanese-speaking children (mean age 3;8) package the semantic elements of Manner and Path onto syntactic units when both the Manner and the Path of the moving Figure occur simultaneously and are salient in the event depicted. Both universal and language-specific patterns were evident in our data. Children used the semantic-syntactic mappings preferred by adult speakers of their own languages, and even expressed subtle syntactic differences that encode different relations between Manner and Path in the same way as their adult counterparts (i.e., Manner causing vs. incidental to Path). However, not all types of semantics-syntax mappings were easy for children to learn (e.g., expressing Manner and Path elements in two verbal clauses). In such cases, Turkish- and Japanese-speaking children frequently used syntactic patterns that were not typical in the target language but were similar to patterns used by English-speaking children, suggesting some universal influence. Thus, both language-specific and universal tendencies guide the development of complex spatial expressions.

  5. Chemical communication of antibiotic resistance by a highly resistant subpopulation of bacterial cells.

    Directory of Open Access Journals (Sweden)

    Omar M El-Halfawy

    Full Text Available The overall antibiotic resistance of a bacterial population results from the combination of a wide range of susceptibilities displayed by subsets of bacterial cells. Bacterial heteroresistance to antibiotics has been documented for several opportunistic Gram-negative bacteria, but the mechanism of heteroresistance is unclear. We use Burkholderia cenocepacia as a model opportunistic bacterium to investigate the implications of heterogeneity in the response to the antimicrobial peptide polymyxin B (PmB and also other bactericidal antibiotics. Here, we report that B. cenocepacia is heteroresistant to PmB. Population analysis profiling also identified B. cenocepacia subpopulations arising from a seemingly homogenous culture that are resistant to higher levels of polymyxin B than the rest of the cells in the culture, and can protect the more sensitive cells from killing, as well as sensitive bacteria from other species, such as Pseudomonas aeruginosa and Escherichia coli. Communication of resistance depended on upregulation of putrescine synthesis and YceI, a widely conserved low-molecular weight secreted protein. Deletion of genes for the synthesis of putrescine and YceI abrogate protection, while pharmacologic inhibition of putrescine synthesis reduced resistance to polymyxin B. Polyamines and YceI were also required for heteroresistance of B. cenocepacia to various bactericidal antibiotics. We propose that putrescine and YceI resemble "danger" infochemicals whose increased production by a bacterial subpopulation, becoming more resistant to bactericidal antibiotics, communicates higher level of resistance to more sensitive members of the population of the same or different species.

    Full Text Available Monocytes are mononuclear cells characterized by distinct morphology and expression of CD14 and CD16 surface receptors. Classical, quiescent monocytes are positive for CD14 (lipopolysaccharide receptor but do not express Fc gamma receptor III (CD16. Intermediate monocytes coexpress CD16 and CD14. Nonclassical monocytes with low expression of CD14 represent mature macrophage-like monocytes. Monocyte behavior in peripheral arterial disease (PAD and during vessel wall directed treatment is not well defined. This observation study aimed at monitoring of acute changes in monocyte subpopulations during percutaneous transluminal angioplasty (PTA in PAD patients. Patients with Rutherford 3 and 4 PAD with no signs of inflammatory process underwent PTA of iliac, femoral, or popliteal segments. Flow cytometry for CD14, CD16, HLA-DR, CD11b, CD11c, and CD45RA antigens allowed characterization of monocyte subpopulations in blood sampled before and after PTA (direct angioplasty catheter sampling. Patients were clinically followed up for 12 months. All 61 enrolled patients completed 12-month follow-up. Target vessel failure occurred in 12 patients. While absolute counts of monocyte were significantly lower after PTA, only subtle monocyte activation after PTA (CD45RA and β-integrins occurred. None of the monocyte parameters correlated with long-term adverse clinical outcome. Changes in absolute monocyte counts and subtle changes towards an activation phenotype after PTA may reflect local cell adhesion phenomenon in patients with Rutherford 3 or 4 peripheral arterial disease.

    Some of the bacterial cells in isogenic populations behave differently from others. We describe here how a new type of phenotypic heterogeneity relating to resistance to cationic antimicrobial peptides (CAMPs) is determinant for the pathogenic infection process of the entomopathogenic bacterium Photorhabdus luminescens. We demonstrate that the resistant subpopulation, which accounts for only 0.5% of the wild-type population, causes septicemia in insects. Bacterial heterogeneity is driven by the PhoPQ two-component regulatory system and expression of pbgPE, an operon encoding proteins involved in lipopolysaccharide (LPS) modifications. We also report the characterization of a core regulon controlled by the DNA-binding PhoP protein, which governs virulence in P. luminescens. Comparative RNAseq analysis revealed an upregulation of marker genes for resistance, virulence and bacterial antagonism in the pre-existing resistant subpopulation, suggesting a greater ability to infect insect prey and to survive in cadavers. Finally, we suggest that the infection process of P. luminescens is based on a bet-hedging strategy to cope with the diverse environmental conditions experienced during the lifecycle. PMID:28252016

    An accurate measurement of the immune status in patients with immune system disorders is critical in evaluating the stage of diseases and tailoring drug treatments. The functional cellular immunity test is a promising method to establish the diagnosis of immune dysfunctions. The conventional functional cellular immunity test involves measurements of the capacity of peripheral blood mononuclear cells to produce pro-inflammatory cytokines when stimulated ex vivo. However, this "bulk" assay measures the overall reactivity of a population of lymphocytes and monocytes, making it difficult to pinpoint the phenotype or real identity of the reactive immune cells involved. In this research, we develop a large surface micromachined poly-dimethylsiloxane (PDMS) microfiltration membrane (PMM) with high porosity, which is integrated in a microfluidic microfiltration platform. Using the PMM with functionalized microbeads conjugated with antibodies against specific cell surface proteins, we demonstrated rapid, efficient and high-throughput on-chip isolation, enrichment, and stimulation of subpopulations of immune cells from blood specimens. Furthermore, the PMM-integrated microfiltration platform, coupled with a no-wash homogeneous chemiluminescence assay ("AlphaLISA"), enables us to demonstrate rapid and sensitive on-chip immunophenotyping assays for subpopulations of immune cells isolated directly from minute quantities of blood samples.

    Objective: The purpose of this study was to determine the root canal anatomy of mandibular first premolar teeth in an Emirati subpopulation using a decalcification and clearing method. Materials and Methods: One hundred permanent mandibular first premolar teeth extracted for orthodontic purposes from an Emirati subpopulation from the United Arab Emirates were used for this study. They were subjected to decalcification and clearing. The tooth length, the canal orifice shape, mesial invagination, canal pattern, the location of apex, presence of lateral canals, and intercanal communications were determined. Results: The most common canal pattern was the Vertucci Type I (65%) followed by Type V (14%) and Type IV (13%). The most common type of canal orifice seen was the oval shape (36%) followed by the round shape (25%). Mesial invaginations were seen in 44% of the teeth. The mean tooth length was 19.9 mm, and apical deltas were seen in 24% of teeth. Conclusion: The Vertucci Type I canal pattern was the most prevalent in the mandibular first premolars while the occurrence of multiple canals was noted in 35% of this population. PMID:26929684

    Exosomes are small (~100nm) membrane bound vesicles excreted by cells as part of their normal biological processes. These extracellular vesicles are currently an area of intense research, since they were recently found to carry functional mRNA that allows transfer of proteins and other cellular instructions between cells. Exosomes have been implicated in a wide range of diseases, including cancer. Cancer cells are known to have increased exosome production, and may use those exosomes to prepare remote environments for metastasis. Therefore, there is a strong need to develop characterization methods to help understand the structure and function of these vesicles. However, current techniques, such as proteomics and genomics technologies, rely on aggregating a large amount of exosome material and reporting on chemical content that is averaged over many millions of exosomes. Here we report on the use of laser-tweezers Raman spectroscopy (LTRS) to probe individual vesicles, discovering distinct heterogeneity among exosomes both within a cell line, as well as between different cell lines. Through principal components analysis followed by hierarchical clustering, we have identified four "subpopulations" of exosomes shared across seven cell lines. The key chemical differences between these subpopulations, as determined by spectral analysis of the principal component loadings, are primarily related to membrane composition. Specifically, the differences can be ascribed to cholesterol content, cholesterol to phospholipid ratio, and surface protein expression. Thus, we have shown LTRS to be a powerful method to probe the chemical content of single extracellular vesicles.

    Full Text Available Abstract Background B-cell lymphomas are thought to reflect different stages of B-cell maturation. Based on cytogenetics and molecular markers, mantle cell lymphoma (MCL is presumed to derive predominantly from naïve, pre-germinal centre (pre-GC B lymphocytes. The aim of this study was to develop a method to investigate the similarity between MCL cells and different B-cell compartments on a protein expression level. Methods Subpopulations of B cells representing the germinal centre (GC, the pre-GC mantle zone and the post-GC marginal zone were isolated from tonsils using automated magnetic cell sorting (AutoMACS of cells based on their expression of CD27 and IgD. Protein profiling of the B cell subsets, of cell lines representing different lymphomas and of primary MCL samples was performed using top-down proteomics profiling by surface-enhanced laser detection/ionization time-of-flight mass spectrometry (SELDI-TOF-MS. Results Quantitative MS data of significant protein peaks (p-value Conclusion AutoMACS sorting generates sufficient purity to enable a comparison between protein profiles of B cell subpopulations and malignant B lymphocytes applying SELDI-TOF-MS. Further validation with an increased number of patient samples and identification of differentially expressed proteins would enable a search for possible treatment targets that are expressed during the early development of MCL.

    Full Text Available Aim of this study is to investigate the role of firm size on capital structure decisions of Turkish lodging companies. In this context, a survey questionnaire is developed and sent to unquoted Turkish lodging companies. 163 lodging companies answered the survey and they are classified according to their sizes. Empirical findings reveal that firm size is a significant factor for capital structure decisions of Turkish lodging companies. Firm size seems to affect lodging companies in using incentives, issuing common stock, using personal debt and determining target debt ratio. Most of the empirical findings seem to support pecking order theory.

    2006-12-01

    Full Text Available This paper investigates whether or not the J-curve hypothesis holds in Turkish agricultural sector. The analysis is conducted using the model the most commonly employed in j-curve literature. Based on the data covering the period from 1986: I to 1998: III, our results indicate that, following devaluation, agricultural trade balance initially improves, then worsens, and then improves again. This pattern shows that J-curve effect does not exist in Turkish agricultural sector. Another important fi nding is that devaluation worsens the trade balance of the sector in the long run, a result contradicting with the earlier fi ndings for the Turkish economy as a whole.

  18. Vulnerability of Turkish coasts to accelerated sea-level rise

    2009-06-01

    Accelerated rise in sea-level, and associated geological adjustment, may result in a high impact on shorelines. On the basis of hourly sea-level observations over a 20 year period, sea-level change along the Turkish coast has been investigated. In addition to relative sea-level rise, the high level of human activities in coastal areas puts a significant amount of stress on Turkish coastal zones, especially on coastal lowland plains. Coastal erosion and ground water salinization are the most important impacts and two case studies are discussed in this paper: the Kizilirmak river delta on the Black Sea; and the tourism center of Erdek on the Marmara Sea. Coastal retreat on the Kizilirmak river delta is mostly attributed to decreasing sediment supply to the coast. The shore barriers and the enclosed lagoons are likely to respond readily to future sea-level rise. At Erdek, the most important threat is intrusion of salt water into freshwater systems caused by a combination of accelerated sea-level rise, land reclamation and overexploitation of underground aquifers.

    This study was conducted to investigate the prevalence of premature ejaculation (PE) in young Turkish men and to evaluate PE in a population having good physical and mental health. A total of 1230 healthy university graduates aged between 24 and 30 attending the police academy having no physical or mental problems were included in the study. To identify the presence of PE, the participants were asked to complete the premature ejaculation diagnostic tool (PEDT). The mean ages in the PE and non-PE group were 27.3 and 26.7 respectively. There was no statistically significant difference between the two groups concerning age, body mass index (BMI), smoking status and alcohol consumption (P > 0.05). The PE prevalence was found to be 9.2%. The mean PEDT score was calculated as 6.3. Of the participants, 92 scored 11 and higher (9.2%), 66 scored 9 and 10 (6.6%), and the remaining 842 obtained a score equal to or lower than 8 (84.2%). The lower prevalence of PE in young Turkish men compared to the results of studies in the literature can be attributed to the physical and mental well-being of the participants. This study showed that the prevalence of PE in young men with good physical and mental health is lower than that found in the literature.

    Full Text Available Folklore has a broad functional area. This function is also one of the first literary folklore products is encountered in language teaching. Folklore products, due to having too many functions, language teaching can be used as both vehicle and purpose. While folklore products, until children have learned the language, used as tool, they can be used as both vehicle and purpose to people have learned the language. Because language learning occurs in different ways, such as individuals with language learning languages learn other things. Only language teaching can be done with a normal text; but many of folklore products that belong to people who speak the language is transferred with with folk-arts text. There are products of folk culture, transfer of functions, regale, etc to give the values and moral education etc. Learning the language, the individual can obtain them. This transfer takes place in foreign language teaching as well as the teaching mother tongue. Folklore products can survive till now, and used in language teaching but they have become used more effectively in language teaching with transferring writing. Because these functions, as well as text to ensure the survival of folklore products must be present in textbooks. Folklore and culture can perform these functions with the Turkish textbook as a tool. In this study, students' textbooks in different provinces across the different folklore and cultural content of the texts in Turkish textbooks, teaching a language as a tool in terms of functions are investigated.

    The present study investigated computer anxiety within a sample of Turkish twins aged 10-18. A total of 185 twin-pairs participated in the study. Of the twins, 64 pairs (34.6 percent) were monozygotic (MZ) and 121 pairs (65.4 percent) were dizygotic (DZ). Of the 121 DZ twins, 54 pairs (44.63 percent) were same-sex twins and 67 pairs (55.37 percent) were opposite-sex twins. Computer anxiety was assessed using Computer Anxiety Rating Scale-Turkish Version (CARS-TV), one of the three main scales of "Measuring Technophobia Instruments" developed by Rosen and Weil. The results of paired t test comparisons showed no significant differences in MZ and same-sex DZ twin-pairs' levels of computer anxiety. On the other hand, a significant difference was found in opposite-sex DZ twin-pairs' level of computer anxiety. Interesting enough, males appeared to be more computer anxious than their female co-twins. In the present study, using Falconer's formula, heritability estimate for computer anxiety was derived from correlations based on MZ and DZ twins' mean scores on CARS-TV. The results showed that 57 percent of the variance in computer anxiety was from genetics and 41.5 percent was from nonshared environmental factors. Shared environmental influence, on the other hand, was very small and negligible. Interpretations of results and potential directions for future research are presented.

    Full Text Available The aim of this study was to investigate physical activity (PA level of the Turkish males who lived in BUrsa. A total of 365 subjects between 18 - 69 age participated to this study. To determine physical activity levels, International Physical Activity Questionnaire (IPAQ was applied. PA levels of subjects were categorized as inactive, minimum active and HEPA active by using MET method. The relations of parameters, such as their age, BMI, education, marital status, number of children, smoking and alcohol use were determined with PA level. The results were analyzed by using Chi - Square test. The participants have 1725 METmin/week average physical activity level, and 47.7 % of them were physically inactive, 30.4 % were physically minimum active and 21.9 % were physically hepa active. As a result, it can be said that the physical activity levels of Turkish males who lived in Bursa are not sufficient and the inactive people are very common.

    Full Text Available In flowering plants, gametophytic self-incompatibility, controlled by a single locus with several allelic variants, is one of the major problems preventing self-fertilization. Among fruit trees, apricots show to a high degree self-incompatibility, especially in Middle-Asian and Iranian-Caucasian eco-geographical groups. In the present study, self-(incompatibility characteristics of a total of 236 apricot genotypes (218 Turkish and 18 foreign found within the National Apricot Germplasms of Apricot Research Institute in Malatya, Turkey was studied. Analyses were carried out by using four primer pairs (SRc-F and SRc-R, EM-PC2consFD and EM-PC3consRD, AprSC8-R and PaConsI-F, AprFBC8-F and AprFBC8-R. A total of 11 S-RNase alleles (S2, S3, S6, S7, S8, S9, S11, S12, S13, S20 and Sc were determined in the 236 apricot genotypes. As Turkish and foreign apricot genotypes are determined mostly self-incompatible, the data obtained hereby might be of good use for apricot breeding programs and more practically, for apricot new plantations; thus pollinator cultivars should be considered when self-incompatible apricot cultivars are being used.

    Full Text Available Aim: We aimed to investigate possibility of different ovarian volume threshold and to study diagnostic thresholds for polycystic ovary in Turkish women, since the literature on this subject is very limited. Material and Method: Clinical study carried out Namik Kemal University School of Medicine, Tekirdag, Turkey.This case-control study included 132 patients with polycystic ovary syndrome (PCOS, diagnosed according to Rotterdam criteria and 75 controls. Comparison of ovarian volumes between PCOS patients and control group. Results: We found a mean ovarian volume of 9.44 ± 4.3 cm3 in PCOS cases and 7.63 ± 3.66 cm3 in control cases. The area under curve (AUC for mean ovarian volume (MOV was 0.633. The analysis showed that setting the threshold of MOV at 8.2 cm3 offered the best compromise between specificity (61.3% and sensitivity (53.8%. Discussion: Optimum threshold of ovarian volume to distinguish the PCOS from normal women and the mean ovarian volume in Turkish PCOS patients remain beneath the criteria by Rotterdam.

In this scope, curriculum of Turkish course was also renewed. This study aimsat evaluating applications and opinions of teachers and students about learning and teaching process prescribed in Turkish Course (1st-5th Grades Curriculum. Within the scope of the study, semi-structured interview was made with 10 teachers and 12 students.In addition, process teaching a text was evaluated via structured observation method in 5 different classes. According to the results of the study, primary school teachers find some stages in learning – teaching process prescribed in the curriculum unnecessary andtherefore do not apply them. Teachers mentioned that some texts are above the student level; and they sometimes experience time and material problems. It was seen in the present study that teachers do not have enough information about learning and teachingprocess in the new curriculum; they do not have high success levels in the applications; and they usually do not apply the forms for evaluating the process in the curriculum. It was found out that, in spite of these problems, courses are student-centred as prescribed inthe curriculum; and students have positive opinions about stages of learning and teaching process.

    Full Text Available By the time of Vladimir Putin’s return to the presidency of Russia in May 2012, the Russian–Turkish rapprochement that began over a decade earlier had become a significant fixture of the Eurasian landscape. Nonetheless, numerous questions remain about the nature of the relation, implications for the region of western Eurasia, and its likely future directions. Four general characteristics of the bilateral relation have emerged, and recognizing them enables a deeper understanding of the opportunities and limits likely to be afforded, for Russia, Turkey, and the region: (a pragmatism, (b a multivectored approach to the bilateral relation, (c commonalities despite contradictions, and (d durability even despite episodic antagonism. The Russian–Turkish rapprochement has become a defining feature of the Eurasian landscape, but remains an unequal one, on several counts: energy resources, geopolitical strength, military capability, and underlying demographics. Nonetheless, various factors make a deepening rapprochement likely: mutual desirability of increased trade, wariness toward the West, Turkey’s pursuit of a “no enemies” foreign policy, Russia’s interest in regional great-power status, and common interest in regional conflict resolution.

    The presence of multiple stellar populations is now well established in most globular clusters (GCs) in the Milky Way. The origin of this phenomenon, however, is yet to be understood. In this respect, the study of NGC 2808, an intriguing GC which hosts subpopulations with extreme helium and light-element abundances, would help to understand this phenomenon. In order to investigate chemical abundance patterns among different subpopulations, we have performed low-resolution spectroscopy for the red-giant-branch stars and measured CN & CH bands, and Ca line strength. We have identified at least three subpopulations from the CN band strength. The CN band strength appears to be more efficient than Na abundance in separating earlier populations. We also find that this GC shows the CN-CH anti-correlation following the general trend of most GCs which are less affected by supernovae enrichment.

    Full Text Available  ABSTRACT The principle that the shareholder of a joint-stock company is under the single obligation of paying in his contribution to the equity-capital is in force within the framework of the 2011 Turkish Commercial Code. It appears as if the reinforced principle of “single obligation” critically challenges the relevance of the formerly settled norm of subjecting increase in shareholders’ commitments to unanimous consent of all shareholders.  That being said, since the Turkish Commercial Code also contains deviations to the single obligation principle in addition to the fact that the notion of increase is shareholders’ commitments was not made entirely obsolete from the Turkish Commercial Code, the doctrine for subjecting increases in shareholders’ commitments to the general assembly’s unanimous vote is - to an extent - still relevant within the context of the 2011 Turkish Commercial Code.

    Background Lateral temporal neural measures (Na and T-complex Ta and Tb) of the auditory evoked potential (AEP) index maturation of auditory/speech processing. These measures are also sensitive to language experience in adults. This paper examined neural responses to a vowel sound at temporal electrodes in four- to five-year-old Spanish-English bilinguals and English monolinguals and in five- to six-year-old Turkish-German bilinguals and German monolinguals. The goal was to determine whether obligatory AEPs at temporal electrode sites were modulated by language experience. Language experience was defined in terms of monolingual versus bilingual status as well as the amount and quality of the bilingual language experience. Method AEPs were recorded at left and right temporal electrode sites to a 250-ms vowel [Ɛ] from 20 monolingual (American)-English and 18 Spanish-English children from New York City, and from 11 Turkish-German and 13 monolingual German children from Ulm, Germany. Language background information and standardized verbal and non-verbal test scores were obtained for the children. Results The results revealed differences in temporal AEPs (Na and Ta of the T-complex) between monolingual and bilingual children. Specifically, bilingual children showed smaller and/or later peak amplitudes than the monolingual groups. Ta-amplitude distinguished monolingual and bilingual children best at right electrode sites for both the German and American groups. Amount of experience and type of experience with the target language (English and German) influenced processing. Conclusions The finding of reduced amplitudes at the Ta latency for bilingual compared to monolingual children indicates that language specific experience, and not simply maturational factors, influences development of the neural processes underlying the Ta AEP, and suggests that lateral temporal cortex has an important role in language-specific speech perception development.

    The aim of this study on cancer mortality among Turkish immigrants, for the first time, traditional comparisons in migrant health research have been extended simultaneously in two ways. First, comparisons were made to cancer mortality from the immigrants' country of origin and second, cancer mortality among Turkish immigrants across four host countries (Belgium, Denmark, France and the Netherlands) was compared. Population-based cancer mortality data from these countries were included. Age-standardized mortality rates were computed for the local-born and Turkish population of each country. Relative differences in cancer mortality were examined by fitting country-specific Poisson regression models. Globocan data on cancer mortality in Turkey from 2008 were used in order to compare mortality rates of Turkish immigrants with those from their country of origin. Turkish immigrants had lower all-cancer mortality than the local-born populations of their host countries, and mortality levels comparable to all-cancer mortality rates in Turkey. In the Netherlands and France breast cancer mortality was consistently lower in Turkish immigrants women than among local-born women. Lung cancer mortality was slightly lower in Turkish immigrants in the Netherlands and France but varied considerably between migrants in these two host countries. Stomach cancer mortality was significantly higher in Turkish immigrants when compared to local-born French and Dutch. Our findings indicate that exposures both in the country of origin and in the host country can have an effect on the cancer mortality of immigrants. Despite limitations affecting any cross-country comparison of mortality, the innovative multi-comparison approach is a promising way to gain further insights into determinants of trends in cancer mortality of immigrants.

    After the collapse of Yugoslavia, the status quo within the Balkans had changed very dramatically in any aspect. In particular, the “new born” states started to attract the attention of the Turkish foreign policy in the sense of defense, security and economic interests. Taking the Turkey’s strong historical and cultural connections with Bosnia and Herzegovina under consideration it is quite possible to investigate the Turkish perspective in the frame of Alexander Wendt’s famous social constru...

    Major surgery as well as endotoxin-induced sepsis is accompanied by lymphocytopenia in peripheral blood. The purpose of this study was to investigate the redistribution of lymphocyte subpopulations and adhesion/activation molecules on lymphocytes. Twenty-four rats were included in the investigation....... Eight rats received an intraperitoneal injection of E. coli endotoxin (2 mg kg-1), eight rats had a sham operation performed while eight rats received isotonic saline and served as a control group. Blood samples were obtained by making an incision in the tail before and 2 and 5 h after surgery...... or administration of endotoxin or saline. After isolation of lymphocytes by gradient centrifugation, flow-cytometric immunophenotyping was performed using CD2, CD3, CD4, CD8, CD11/CD18, CD20, CD44 and MHC II monoclonal antibodies. Endotoxemia and surgery were both accompanied by increased serum cortisol...

    Quantitative determinations of lymphocytas were done in the active period of the disease, immediately after treatment by the COAP schedule and during remission. In 6 patients the determinations were done several times during 20 weeks of maintenance treatment. It was found that independently of the stage of the disease the absolute lymphocyte count and the counts of B and T populations were low, while that of lymphocyte O population was raised. It was observed that the reduced count concerned all 4 subclasses of lymphocytes B, that is those with surface receptors for IgA, IgM, IgG and IgE immunoglobulins. In remission the values of lymphocytes and their T and B subpopulations increased, failing, however, to reach the normal values. This rise was more pronounced in the case of lymphocytes T. Lymphocyte depression in these patients is explained by the authors as due mainly to intensive cytostatic treatment.

    Full Text Available Periodontal disease and chronic apical periodontitis are considered risk factors for cardiovascular diseases. This cross-sectional study, performed in a subpopulation living in the South area of Romania, investigated the association between the afore-mentioned oral lesions and atherosclerosis. The research was focused on common carotid artery intima-media wall thickness IMT and dislipidemia, in a batch of 30 hypertensive subjects, age 41-50. Over 40% of the patients diagnosed with periodontal disease and/or chronic apical periodontitis developed subclinical atherosclerosis. Associated dyslipidemia to an increased IMT over 0.9 mm in subjects affected by periodontal disease or combined lesions with chronic apical periodontitis might be considered a strong predictor of future cardiovascular events.

    Cyanobacterial oligopeptides comprise a wide range of bioactive and/or toxic compounds. While current research is strongly focused on exploring new oligopeptide variants and their bioactive properties, the biological role of these compounds remains elusive. Oligopeptides production abilities show a remarkably patchy distribution among conspecific strains. This observation has prompted alternative approaches to unveil their adaptive value, based on the use of cellular oligopeptide compositions as biomarkers of intraspecific subpopulations or chemotypes in freshwater cyanobacteria. Studies addressing the diversity, distribution, and dynamics of chemotypes in natural systems have provided important insights into the structure and ecology of cyanobacterial populations and the adaptive value of oligopeptides. This review presents an overview of the fundamentals of this emerging approach and its most relevant findings, and discusses our current understanding of the role of oligopeptides in the ecology of cyanobacteria.

    Full Text Available The movement analysis in “Bar”, Which is a type of Turkish Folk Dances, the main subject of this article. Three regions Erzurum, Bayburt and Erzincan are chosen to determine the basic movements that are most used in “Bar”. The basic movements are determined by examining 7 or 8 dances for 3 regions, namely 23 dances in sum. The similar and different characteristics of the sort are revealed by examining the arm positions and basic figures in body parts, which are used in these dances. In the study, first of all, video records that were recorded in the interviews with the regional folk dance trainers, various folk dance shows and folk dance competitions, are transformed into digital environment by Asus Live Video to have bmp and jpeg formats for examining the body movements with the aim of determining them. As a result of this work, the photos are taken and examined in digital environment. By analyzing these determined basic movements that are used in “Bar” dances in the respect of anatomy also, the anatomy terms, which are used by the medicine, anatomy and kinetics scholars in the whole world internationally are employed for the explanations of the movements due to the lack of the written terminology of Turkish folk dances. In the conclusion part, the necessity of movement analysis and its advantages provided for education and training of folk dance are mentioned. Also this article is the first study which puts movement analysis about “Bar” into practice in Turkish folk dances. This article was prepared at Istanbul Technical University Institute of Social Sciences, supported by Istanbul Technical University Scientific Research Projects Unit; "Determination of the Basic Movements Used in Folk Dances and Their Anatomical Analysis" is derived from the thesis Proficiency. The project examined five different types of folk dances. But from within the only “Bar” dances on the subject by examining the forms of movement, some stickers

    Full Text Available In this communiqué again we preferred to present some examples from the effects of Turkish Cypriot Culture. For a few years, we have concentrated on our culture’s effect on other cultures in Cyprus. Bearing in mind that we have lived together for hundreds of years with other societies, we have seen fit to give examples of the cultural interaction between other cultures and Turkish Cypriot culture. Our communiqué mostly comprises the effects of Turkish Culture. We have found it convenient to present idioms rather than words. As it can be seen from the examples, in every Greek saying there is a Turkish word. For that reason, we have chosen our title as “Turkish Idioms in Greek Cypriot Language”. These idioms which have the clear evidence of the effect of Turkish Culture have been limited with only 71 examples due to shortage of time. We are happy to be able to contribute to our culture. Now with our best regards we would like to start presenting the examples.

    This article reports on an ethnopharmaceutical field study carried out among Turkish migrants in Cologne, western Germany, which recorded 79 botanical taxa and 115 plant-based preparations, encompassing 167 folk phytotherapeutical uses, as well as a few other biological (animal and mineral derived) remedies. One-fourth of the recorded remedies were represented by food-medicines. Half of the ingredients quoted came originally from Turkey; only a few plants were gathered from the wild or cultivated in the Cologne area. This article discusses the Turkish migrants' frequent use of aerial parts of Sideritis species, the fruits of Pistacia terebinthus and the seeds of Peganum harmala from the perspective of modern phytopharmacology, phytotherapy and toxicology. It considers cultural adaptation related to the use of folk pharmaceuticals by analysing the ingredients of the Turkish folk pharmacopoeia and comparing them with those of the Turkish medical ethnobotany and of the phytotherapy of the host country (Germany). Only one third of the remedies mentioned by Turkish migrants living in Cologne are also known in German evidence-based phytotherapy, and less than 10% of the recorded phytotherapeutic uses are common to both pharmacopoeias. This article concludes by suggesting hypotheses on future changes affecting the knowledge and use of medicinal plants within the Turkish community of Cologne.

    The aim of the study was to evaluate markers of the acute phase response (APR) in eventing horses by measuring acute phase proteins (APP) (haptoglobin, Hp, and serum amyloid A, SAA), lysozyme, protein adducts such as pentosidine-like adducts (PENT), malondialdehyde adducts (MDA), hydroxynonenal adducts (HNE) and total advanced glycation/glycoxidation end products (AGEs), complete blood count and lymphocyte subpopulations (CD4+, CD8+ and CD21+) both at rest and at the end of an eventing competition. Blood samples were collected from eight Warmblood horses (medium age 10 ± 3) during an official national 2-day event competition at rest (R) and 10 min after the arrival of the cross-country test on the second day. Exercise caused a significant increase in red blood cell number, haemoglobin, packed cell volume, neutrophils, white blood cell and lymphocyte number; however, these values remained within the normal range. The CD4+ and CD8+ cells significantly increased, whereas the CD21+ lymphocytes decreased; a significant increase in serum SAA, lysozyme and protein carbonyl derivates was also observed. Two-day event causes significant changes in APR markers such as lysozyme, protein carbonyl derivates (HNE, AGEs, PENT) and lymphocyte subpopulations. The data support the hypothesis that 2-day event may alter significantly APR markers. Limitations of the study were the relatively small sample size and sampling time conditioned by the official regulations of the event. Therefore, further studies are needed to investigate the time required for recovery to basal values in order to define the possible effects on the immune function of the athlete horse.

    The purpose of this study was to conduct a cone-beam computed tomographic (CBCT) investigation on the root and canal configuration of the mandibular first molars, especially the morphology of the disto-lingual (DL) root, in a Chinese subpopulation. A total of 910 CBCT images of the mandibular first molars were collected from 455 patients who underwent CBCT examinations as a preoperative assessment for implants or orthodontic treatment. The following information was analyzed and evaluated: tooth position, gender, root and root canal number per tooth, root canal type of the mesial root(s) and distal root(s), angle of the DL root canal curvature, distance between two distal canal orifices in the teeth with DL root, and angle of disto-buccal canal orifice-disto-lingual canal orifice-mesio-lingual canal orifice (DB-DL-ML). Most of the mandibular first molars (64.9%, n = 591) had two roots with three root canals, and most of the mesial root canals (87.7%, n = 798) were type VI. The prevalence of the DL root was 22.1% (n = 201). The right side had a higher prevalence of DL root than the left side (p<0.05). Additionally, the curvature of the DL root canal were greater in the bucco-lingual (BL) orientation (30.10°±14.02°) than in the mesio-distal (MD) orientation (14.03°± 8.56°) (p<0.05). Overall there was a high prevalence of DL root in the mandibular first molars, and most of the DL roots were curved in different degrees. This study provided detailed information about the root canal morphology of the mandibular first molars in a Chinese subpopulation.

    2016-07-01

    Full Text Available Streptococcus mutans activates multiple cellular processes in response to the formation of a complex between comX-inducing peptide (XIP and the ComR transcriptional regulator. Bulk phase and microfluidic experiments previously revealed that ComR-dependent activation of comX is altered by pH and by carbohydrate source. Biofilm formation is a major factor in bacterial survival and virulence in the oral cavity. Here, we sought to determine the response of S. mutans biofilm cells to XIP during different stages of biofilm maturation. Using flow cytometry and confocal microscopy, we showed that exogenous addition of XIP to early biofilms resulted in robust comX activation. However, as the biofilms matured, increasing amounts of XIP were required to activate comX expression. Single-cell analysis demonstrated that the entire population was responding to XIP with activation of comX in early biofilms, but only a sub-population was responding in mature biofilms. The sub-population response of mature biofilms was retained when the cells were dispersed and then treated with XIP. The proportion and intensity of the bi-modal response of mature biofilm cells was altered in mutants lacking the Type II toxins MazF and RelE, or in a strain lacking the (pppGpp synthase/hydrolase RelA. Thus, competence signaling is markedly altered in cells growing in mature biofilms, and pathways that control cell death and growth/survival decisions modulate activation of comX expression in these sessile populations.

    Shannon entropy H and related measures are increasingly used in molecular ecology and population genetics because (1) unlike measures based on heterozygosity or allele number, these measures weigh alleles in proportion to their population fraction, thus capturing a previously-ignored aspect of allele frequency distributions that may be important in many applications; (2) these measures connect directly to the rich predictive mathematics of information theory; (3) Shannon entropy is completely additive and has an explicitly hierarchical nature; and (4) Shannon entropy-based differentiation measures obey strong monotonicity properties that heterozygosity-based measures lack. We derive simple new expressions for the expected values of the Shannon entropy of the equilibrium allele distribution at a neutral locus in a single isolated population under two models of mutation: the infinite allele model and the stepwise mutation model. Surprisingly, this complex stochastic system for each model has an entropy expressable as a simple combination of well-known mathematical functions. Moreover, entropy- and heterozygosity-based measures for each model are linked by simple relationships that are shown by simulations to be approximately valid even far from equilibrium. We also identify a bridge between the two models of mutation. We apply our approach to subdivided populations which follow the finite island model, obtaining the Shannon entropy of the equilibrium allele distributions of the subpopulations and of the total population. We also derive the expected mutual information and normalized mutual information ("Shannon differentiation") between subpopulations at equilibrium, and identify the model parameters that determine them. We apply our measures to data from the common starling (Sturnus vulgaris) in Australia. Our measures provide a test for neutrality that is robust to violations of equilibrium assumptions, as verified on real world data from starlings.

    We analyzed the distribution and light-microscopic features of the NADPH diaphorase-containing structures in the lizard hippocampus, likely to correspond to nitric oxide synthase-containing cells and fibers, and thus likely to release nitric oxide. We also studied co-localization of NADPH diaphorase with the neurotransmitter GABA, the calcium-binding protein parvalbumin, and the neuropeptide somatostatin, in order to examine whether putative nitric oxide-synthesizing neurons represent a different subpopulation of GABA cells, on which the authors recently reported in lizards. We also studied co-localization of NADPH diaphorase with parvalbumin or somatostatin in mice to ascertain whether the characteristics of this population in reptiles parallel the situation in mammals. Most of the positive NADPH diaphorase neurons were stained in a Golgi-like manner and were in the plexiform layers of the lizard hippocampus with morphologies ranging from bipolar to multipolar. Co-localization with GABA was 100%, and NADPH diaphorase-positive neurons in the lizard hippocampus did not contain parvalbumin or somatostatin. The results indicate that putative nitric oxide-synthesizing neurons represent a distinct subpopulation of GABA interneurons in the lizard hippocampus. Two different types of fibers were described in the plexiform layers: one type bearing thick varicosities, and the other thinner ones. We discuss the possibility that at least part of the positive fibers arise from a hypothalamic aminergic nucleus contacting the third ventricle, the periventricular hypothalamic organ. Most radial glia were stained almost completely and formed typical end-feet both at the pia and around capillaries. The results of this study confirm that the capacity for synthesizing nitric oxide is linked to a determined set of neuronal markers depending on the specific brain region, and they provide new resemblances between hippocampal regions in different classes of vertebrates.

  15. Interleukin-17 induces an atypical M2-like macrophage subpopulation that regulates intestinal inflammation.

    Directory of Open Access Journals (Sweden)

    Kenichiro Nishikawa

    Full Text Available Interleukin 17 (IL-17 is a pleiotropic cytokine that acts on both immune and non-immune cells and is generally implicated in inflammatory and autoimmune diseases. Although IL-17 as well as their source, mainly but not limited to Th17 cells, is also abundant in the inflamed intestine, the role of IL-17 in inflammatory bowel disease remains controversial. In the present study, by using IL-17 knockout (KO mice, we investigated the role of IL-17 in colitis, with special focus on the macrophage subpopulations. Here we show that IL-17KO mice had increased susceptibility to DSS-induced colitis which was associated with decrease in expression of mRNAs implicated in M2 and/or wound healing macrophages, such as IL-10, IL-1 receptor antagonist, arginase 1, cyclooxygenase 2, and indoleamine 2,3-dioxygenase. Lamina propria leukocytes from inflamed colon of IL-17KO mice contained fewer CD11b+Ly6C+MHC Class II+ macrophages, which were derived, at least partly, from blood monocytes, as compared to those of WT mice. FACS-purified CD11b+ cells from WT mice, which were more abundant in Ly6C+MHC Class II+ cells, expressed increased levels of genes associated M2/wound healing macrophages and also M1/proinflammatory macrophages. Depletion of this population by topical administration of clodronate-liposome in the colon of WT mice resulted in the exacerbation of colitis. These results demonstrate that IL-17 confers protection against the development of severe colitis through the induction of an atypical M2-like macrophage subpopulation. Our findings reveal a previously unappreciated mechanism by which IL-17 exerts a protective function in colitis.

  16. Divergence Effect at Alaska's Treelines a Result of Sub-Population Behavior?

    The "divergence effect" (off-set between tree-ring based temperature reconstruction and measured temperatures) in northern forest poses a serious question to tree-ring based climate reconstructions, since it seems to violate the uniformitarian principle of dendroclimatology. Several possible reasons emerge, among them false assumptions about 1) climate data (e.g. which climate parameter can be modeled most effectively), 2) tree-ring data (e.g. shift in climate sensitivity of tree growth) or 3) a truly new and unprecedented phenomenon (e.g. rapid climate warming exceeding the adaptive capacity of trees). Here we test, if undetected emergent sub-population behavior at Alaska's treelines might result in a divergence effect. We reanalyzed seven data sets spanning the entire northern treeline in the Brooks Range, Alaska, which showed populations of trees responding positively, non-significant and negatively to recent warming. There is no effect of standardization (i.e. conventional versus RCS) technique on the grouping and we thus used RCS for the following analysis. Without grouping into sub- populations, a clear divergence between tree-ring based temperature reconstruction and actual climate data emerged. However, if only those trees were used for the climate reconstruction, which showed a consistent positive response to the target temperatures (June/July), tree growth modeled climate data extremely well following the rise in temperature during the last decades (actual climate data 0.53°/decade versus tree-ring based reconstruction 0.44°/decade over 1970-2000 period). This result hints at the possibility that some of the reported divergence might be eliminated (at least at Alaska's treelines) through careful test of sub-population behavior.

    Despite recent general improvements in health care, significant disparities persist in the cardiovascular care of women and racial/ethnic minorities. This is true even when income, education level, and site of care are taken into consideration. Possible explanations for these disparities include socioeconomic considerations, elements of discrimination and racism that affect socioeconomic status, and access to adequate medical care. Coronary revascularization has become the accepted and recommended treatment for myocardial infarction(MI) today and is one of the most common major medical interventions in the United States, with more than 1 million procedures each year. This review discusses recent data on disparities in co-morbidities and presentation symptoms, care and access to medical resources, and outcomes in revascularization as treatment for acute coronary syndrome, looking especially at women and minority populations in the United States. The data show that revascularization is used less in both female and minority patients. We summarize recent data on disparities in co-morbidities and presentation symptoms related to MI; access to care, medical resources, and treatments; and outcomes in women, blacks, and Hispanics. The picture is complicated among the last group by the many Hispanic/Latino subgroups in the United States. Some differences in outcomes are partially explained by presentation symptoms and co-morbidities and external conditions such as local hospital capacity. Of particular note is the striking differential in both presentation co-morbidities and mortality rates seen in women, compared to men, especially in women ≤ 55 years of age. Surveillance data on other groups in the United States such as American Indians/Alaska Natives and the many Asian subpopulations show disparities in risk factors and co-morbidities, but revascularization as treatment for MI in these populations has not been adequately studied. Significant research is required to

    A fundamental question in psycholinguistic research concerns the universality of comprehension strategies. We investigated this issue by examining the so-called "subject preference" in Turkish, a language which allows for a natural (unmarked) object reading of an initial ambiguous argument. Using event-related brain potentials (ERPs), we observed increased processing difficulty in the form of a broadly distributed positivity when an initial ambiguous argument was disambiguated towards an object reading. This effect was independent of the animacy (i.e. semantic subject prototypicality) of the ambiguous argument. Our results therefore speak in favour of a universal tendency to interpret the first argument encountered as the "subject" of the clause, even in languages providing no obvious structural motivation for such a strategy. However, we argue that the underlying explanation for this preference must be modified in accordance with cross-linguistic considerations.

    Full Text Available Who will meet the financing of education cost, or in other words sponsorship to education, has traditionally been a social concern as in other teaching steps. Actually, this discussion is closely related to inner and outer obstacles and financial matters as well as required qualifications and efficiency of education.As the scope of the finance in education is the state, the scope of the finance in higher education is the state itself because higher education has been, so far, heavily considered as a public service whose expenses are extensively met through public sources in each country except the USA and several other countries. However, the financing of the cost of the increasing demand to higher education only with social sources is nowadays being interrogatedHigher education is a service of high cost. Financing ways of higher education in various countries range a large spectrum from institutions sponsored only by students’ contribution fees without any other supports else for institutions whose all higher educational expenses, including feeding and accommodation, are completely met through social sources.Financing of Turkish Higher Education service is mostly handled two different models: the state and foundation universities. The first one, state’s universities, have traditionally adopted “a financial system relying on national sources” while foundation ones have developed their own “exclusive financing”. Today, budget financing accounts for nearly %80 of the budget allocated for state’s universities. In the year 1973, the classical budge system was replaced by “program budget system”, and then in 1998 was converted into a joint budget system. The current system, analytic budget system” has been in practice since 2004. However, in foundation universities, the main approach is treasure aids to make contributions to their expenses provided it remains limited with the payment in the budgetDespite the increase in the number

    This article investigates the possibility of using trona minerals in the oxydesulfurization of coal. The experiments were performed on a Turkish lignite having high organic and high pyritic sulfur content from the Gediz area. Oxydesulfurization of the lignite sample using trona minerals was studied at 423--473 K, under 0--1 MPa oxygen partial pressure at 0--0.3 M equivalent alkalinity of Na{sub 2}CO{sub 3} for 2.5--60 min. Almost all of the pyritic sulfur content and, depending on the working conditions, an important part of the organic sulfur content were removed. Unless the temperature reached 473 K, solid product yield was not negatively affected. Trona minerals were seen as a suitable alkaline to use in oxydesulfurization of coal.

    A new Turkish Penal Code came into effect on 1 June 2005. Article 280 concerns health care workers' failure to report a crime. This article removes the responsibility from health care workers to maintain confidentiality, but also removes patients' right to confidentiality. It provides for up to one year of imprisonment for a health care worker who, while on duty, finds an indication that a crime might have been committed by a patient and who does not inform the responsible authorities about it. This forces the health care worker to divulge the patient's confidential information. A patient who thinks he or she may be accused of a crime may therefore not seek medical help, which is the universal right of every person. The article is therefore contrary to medical ethics, oaths taken by physicians and nurses, and the understanding of patient confidentiality.

    Full Text Available Raki is an aniseed flavoured traditional Turkish alcoholic drink. Antioxidant capacity of raki samples from different commercial brands were evaluated by CUPRAC, DPPH, TEAC and ORAC assays and correlations between these assays and total phenolic content were also investigated. Additionally, the one-way ANOVA and Bonferroni tests were performed to compare differences between values of the samples. Results indicated that different raki samples exhibited different antioxidant capacity and total phenolic content. The mean antioxidant capacity values of samples were in the order of: ORAC>TEAC>CUPRAC>DPPH. The correlations of total phenolic content of samples with their CUPRAC, TEAC and ORAC results were found statistically significant, while DPPH assay showed no significant correlation.

    2012-02-01

    In the Harmancık-Bursa region of the western Anatolia (Turkey), an extensive contact metamorphic aureole at the border between the Late Mesozoic coherent metaclastic rocks of blueschist facies and the Early Senozoic intrusive granodiorite stock hosts an interesting and unique gem material with a mineral assemblage consisting mainly of jadeite, quartz, orthoclase, epidote, chloritoid, and phlogopite as identified by X-ray diffraction spectroscopy and polarized-light microscopy. In addition, chemical analyses performed with X-ray fluorescence and inductive-coupled plasma-atomic emission spectroscopy show that the mass of the metamorphic aureole has a silica-rich, calc-alkaline chemical content. Therefore, some rock building elements (such as Al, Ca, Na, K, P, Sr, and B of which characterize an acidic-neutral rock formation) and trace elements (such as Fe, Cr, Mn, Be, Cu, Ga, La, Ni, Pb, and Zn) are remarkable high ratios. Pale purple-colored gem material of this composition appears to be unique to Turkey, also is only found in one narrow provenance in Turkey. Therefore, it is specially called "Turkish (and/or Anatolian) purple jade" on the worldwide gem market. Even though the mineral jadeite is the principal constituent, 40% by volume as determined with petrographic thin-section examination under a polarized-light microscope, the material cannot be considered pure jadeite. Specific gravity measurements of the jade using a hydrostatic balance confirm that it has a heterogeneous structure. The measured average specific gravity of 3.04, is significantly lower than the normal range for characterized jadeites of 3.24-3.43. Turkish purple jade samples were examined in detail using dispersive confocal micro-Raman spectroscopy (DCμRS) as well as other well-known analytical methods. The resulting strong micro-Raman bands that peaked at 1038, 984, 697, 571, 521, 464, 430, 372, 326, 307, 264, and 201 cm -1 are characteristics of the Turkish purple jade. The first most

    The study reported describes the phonological rules typical of normal development of Turkish-speaking children. The processes identified include: reduplication, syllable deletion, consonant deletion, assimilation, cluster reduction, liquid deviation, stopping, fronting, affrication, and backing. From a crosslinguistic perspective, the phonological process patterns exhibited coincide broadly with universal tendencies, although some language specific patterns were also evident. In contrast, a case study of a phonologically disordered child indicated that her system was characterised by the use of idiosyncratic phonological rules as well as delayed acquisition of some aspects of the system. This atypical pattern reflects reports of phonologically disordered children learning other languages. The findings indicate that the deficit underlying this type of phonological disorder leads to similar phonological behavior irrespective of the language being acquired.

    For centuries, in the Eastern Mediterranean region, medicinal plant use has been widely accepted as a treatment method for both minor and major diseases. Although some knowledge exists on the use of such medicinal plants within the Greek Cypriot culture and considerable information is available on various regions in Turkey, no detailed ethnopharmaceutical or ethnobotanical studies exist on Turkish-speaking Cypriots (TSC) both in Cyprus and within one of the largest TSC migrant communities in London, UK. Semi-structured interviews with members of the TSC community in London were conducted by using a questionnaire consisting both of open and closed questions. Open questions were aimed at identifying herbs, spices, medicinal plants and their uses. Also, graded questions were used to define informants' opinions as a quantitative parameter, constructing a statistical basis. A wide range of therapeutic claims were recorded, including 13 chronic illnesses within 85 different plant species, of which 18 were cited more than 10 times. The most frequently mentioned species were Mentha spicata, Salvia fruticosa and Pimpinella anisum. The plants recorded are frequently based on knowledge derived from Turkish-Cypriot traditions, but many examples of medicinal plants with a use based on UK or general western herbal medical traditions were also recorded. Informants highlighted the risk of knowledge loss in younger generations and thus this study serves as a repository of knowledge for use in the future. Due to a lack of knowledge about such usages in the healthcare professions, our study also highlights the need to develop information sources for use by healthcare practitioners in order to raise awareness about benefits and risks of such medical and health food products.

    Full Text Available Background: Infertility is a major psychosocial crisis as well as being a medical problem. The factors that predict psychosocial consequences of infertility may vary in different gender and different infertile populations.Objective: The primary purpose of this study was to investigate whether Turkish infertile couples had higher levels of depression and anxiety when compared to non-infertile couples. Our secondary aim was to evaluate the relationship between sociodemographic characteristics and levels of depression and anxiety in Turkish infertile couples.Materials and Methods: We designed a descriptive cross sectional study of 248 infertile women and 96 infertile men with no psychiatric disturbance and 51 women and 40 men who have children to evaluate the depression and anxiety levels between infertile couples and fertile couples. A gynecologist evaluated participants for demographic data and then they were visited by a psychologist to perform questionnaire scales which were The Beck Depression Inventory and the State-Trait Anxiety Inventory for the evaluation of the degree of psychopathology. The data were statistically analyzed, with p<0.05 as the level of statistical significance.Results: We observed significant differences between the infertile couples and fertile couples with respect to state and trait anxiety (p<0.0001 while no difference was regarding with depression, both of women and men. Anxiety and depression were observed as independent from gender when infertile women and men were compared (p=0.213.Conclusion: We believed that the psychological management at infertile couples must be individualized with cultural, religious, and class related aspects.

    Full Text Available This article describes the foundation of ‘Pediatric Nephrology’ in Turkey including the first steps in the international arena, the achievements in institutionalisation of services and training of pediatricians, and the renal care offered to pediatric patients suffering from kidney diseases. The world history of pediatric nephrology dates back to the 1960ies and 1970ies when the pioneers of pediatric nephrology including Ihsan Dogramaci, the great mentor with a cosmopolitain vision, paid much attention to pediatric nephrology, thus initiating the process of implementing pediatric nephrology in Turkey and in Europe. In the year 1983, Pediatric Nephrology achieved the status of a subspecialty in Pediatrics in Turkey. The founding of the Turkish Society of Pediatric Nephrology in 1990 provided the basis for standardization and institutionalisation of training in pediatric nephrology; and it also accelerated the development of clinical studies and experimental research. The construction of well-equipped modern hospitals as well as the financial support by both universities and pharmaceutical industry played important roles in the rapid increase in scientific activities. In 2012, nearly 150 well-trained specialists are the basis for a high standard of clinical care and for publishing activities, thus putting Turkey into the front line of publications and of congress presentations in the world. Today, Turkey has 50 pediatric nephrology centers including 19 pediatric hemodialysis units, 39 pediatric peritoneal dialysis units and 16 pediatric transplantation centers. The achievements of the founding generation include the participation at international congresses, the organization of a European congress of Pediatric Nephrology in Istanbul and the active cooperation with well-known experts in ESPN and IPNA councils. The new generation of Turkish pediatric nephrologists is well prepared to take over the mission they have learned from the pioneers, and

Clinical findings were obtained by using the Unified Parkinson’s Disease Rating Scale. Disease severity was measured by the Hoehn and Yahr staging scale, and the Schwab and England Activities of Daily Living scale was used for patient disability. Psychiatric evaluation was performed by the same psychiatrist using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (DSM-IV Axis I Disorders. Severity of depression was measured with the Hamilton Depression Rating Scale. Suicidal ideation and attempts were considered positive if experienced during the patient’s lifetime. The Suicide Probability Scale was used to assess the risk of suicide. Data were analyzed by logistic regression models to identify variables associated with suicidal ideation and attempts.Results: Based on logistic regression analysis, education level, age of disease onset, disease duration, depression, and history of impulse-control disorder (ICD behaviors were significant predictors of suicidal ideation. The risk rate in the presence of depression and history of ICD behaviors was increased by 5.92 and 4.97, respectively. Additionally, lifetime prevalence of suicidal ideation was found in 11.6% (14 of 120 of PD patients, although no patient had ever attempted suicide.Conclusion: Turkish patients with PD who exhibit a high risk for suicidal ideation also experience disease starting at an earlier age, longer disease duration, presence of depression, and ICD behaviors, and should be monitored carefully.Keywords: Parkinson’s disease, suicidal behavior, risk factors

    Diet is highly linked to breast cancer risk, yet little is known about its influence on mammary epithelial populations with distinct regenerative and hence, tumorigenic potential. To investigate this, we evaluated the relative frequency of lineage-negative CD29(hi)CD24(+), CD29(lo)CD24(+) and CD29(hi)Thy1(+)CD24(+) epithelial subpopulations in pre-neoplastic mammary tissue of adult virgin MMTV-Wnt1-transgenic mice fed either control (Casein) or soy-based diets. We found that mammary epithelial cells exposed to soy diet exhibited a lower percentage of CD29(hi)CD24(+)Lin(-) population, decreased ability to form mammospheres in culture, lower mammary outgrowth potential when transplanted into cleared fat pads, and reduced appearance of tumor-initiating CD29(hi)Thy1(+)CD24(+) cells, than in those of control diet-fed mice. Diet had no comparable influence on the percentage of the CD29(lo)CD24(+)Lin(-) population. Global gene expression profiling of the CD29(hi)CD24(+)subpopulation revealed markedly altered expression of genes important to inflammation, cytokine and chemokine signaling, and proliferation. Soy-fed relative to casein-fed mice showed lower mammary tumor incidence, shorter tumor latency, and reduced systemic levels of estradiol 17-β, progesterone and interleukin-6. Our results provide evidence for the functional impact of diet on specific epithelial subpopulations that may relate to breast cancer risk and suggest that diet-regulated cues can be further explored for breast cancer risk assessment and prevention.

    Members of the pathogenic Legionella genus encounter suitable growth conditions in nuclear power plant cooling circuits. To limit its proliferation and ensure that levels remain below regulatory thresholds, chemical treatment with monochloramine can be used in continuous or sequential conditions. The aim of this study was to determine the impact of monochloramine on L. pneumophila subpopulations in the cooling circuits of a nuclear power plant. The chosen procedure involved monitoring the diversity and dynamics of L. pneumophila subpopulations every month over the course of a year in a nuclear power plant cooling circuit, which was treated for 2 months during the period under study. This study confirmed the effectiveness of monochloramine to limit L. pneumophila concentrations in cooling circuits. The culturable L. pneumophila community was strongly affected by the injection of monochloramine. Several subpopulations persisted during treatment at low concentrations (below the detection limit of standard methods), suggesting that the susceptibility of L. pneumophila is strain dependent. Although the composition of the subpopulations was not similar, the resilience of the community structure was observed. Indeed, the community eventually returned to its initial structure and presented a similar pattern of richness, diversity and uniformity to that seen before treatment.

    Full Text Available Deforestation and exploitation has led to the fragmentation of habitats and scattering of populations of the economically important eri silkworm, Samia cynthia ricini, in north-east India. Genetic analysis of 15 eri populations, using ISSR markers, showed 98% inter-population, and 23% to 58% intra-population polymorphism. Nei's genetic distance between populations increased significantly with altitude (R² = 0.71 and geographic distance (R² = 0.78. On the dendrogram, the lower and upper Assam populations were clustered separately, with intermediate grouping of those from Barpathar and Chuchuyimlang, consistent with geographical distribution. The Nei's gene diversity index was 0.350 in total populations and 0.121 in subpopulations. The genetic differentiation estimate (Gst was 0.276 among scattered populations. Neutrality tests showed deviation of 118 loci from Hardy-Weinberg equilibrium. The number of loci that deviated from neutrality increased with altitude (R² = 0.63. Test of linkage disequilibrium showed greater contribution of variance among eri subpopulations to total variance. D'2IS exceeded D'2ST, showed significant contribution of random genetic drift to the increase in variance of disequilibrium in subpopulations. In the Lakhimpur population, the peripheral part was separated from the core by a genetic distance of 0.260. Patchy habitats promoted low genetic variability, high linkage disequilibrium and colonization by new subpopulations. Increased gene flow and habitat-area expansion are required to maintain higher genetic variability and conservation of the original S. c. ricini gene pool.

    An exploratory, post hoc analysis was performed using data from a prospective, multicenter, open-label, randomized, two-period (14 d per period), two-sequence, crossover, steady-state pharmacokinetic study comparing generic tacrolimus (Sandoz) vs. reference tacrolimus in stable renal transplant patients receiving their pre-study twice-daily dose. Pharmacokinetic parameters were compared in 68 patients according to gender, African American ethnicity, the presence or absence of diabetes, and use of steroids. The ratios of tacrolimus AUC0-12 h , Cmax , and C12 with generic vs. reference tacrolimus were calculated using the geometric mean (GM) of dose-normalized values at days 14 and 28. Mean (SD) tacrolimus dose at baseline was 5.7 (4.2) mg/d. There were no consistent differences in dose-normalized AUC0-12 h , C12 , Cmax, or tmax between the generic and reference preparations within subpopulations. The 90% confidence intervals (CI) for the ratios of dose-normalized AUC0-12 h and C12 with generic vs. reference tacrolimus were within 80-125% for all subpopulations, as were 90% CIs for Cmax other than for females, African Americans, and non-diabetics, which is not unexpected given the wide variability of tacrolimus Cmax and the small subpopulation sizes. These exploratory results suggest that this generic tacrolimus preparation would be expected to offer comparable bioavailability to the reference drug in these patient subpopulations.

  1. Optimal Tests of Treatment Effects for the Overall Population and Two Subpopulations in Randomized Trials, using Sparse Linear Programming.

    2014-01-01

    We propose new, optimal methods for analyzing randomized trials, when it is suspected that treatment effects may differ in two predefined subpopulations. Such subpopulations could be defined by a biomarker or risk factor measured at baseline. The goal is to simultaneously learn which subpopulations benefit from an experimental treatment, while providing strong control of the familywise Type I error rate. We formalize this as a multiple testing problem and show it is computationally infeasible to solve using existing techniques. Our solution involves a novel approach, in which we first transform the original multiple testing problem into a large, sparse linear program. We then solve this problem using advanced optimization techniques. This general method can solve a variety of multiple testing problems and decision theory problems related to optimal trial design, for which no solution was previously available. In particular, we construct new multiple testing procedures that satisfy minimax and Bayes optimality criteria. For a given optimality criterion, our new approach yields the optimal tradeoff between power to detect an effect in the overall population versus power to detect effects in subpopulations. We demonstrate our approach in examples motivated by two randomized trials of new treatments for HIV.

    In summary, this research has investigated the effects of combined modality treatment (i.e., low linear energy transfer ionizing radiation and hyperthermia at 42.5 degrees C) on the survival responses of two tumour subpopulations (designated clones A and D) obtained from a heterogeneous human colon adenocarcinoma. A constant hyperthermic exposure (2 hours at 42.5 degrees C) was given either 3 min before or 3 min after graded exposure to X-rays. An isobologram analysis (Steel and Peckham 1979) of the clonogenic survival responses of the two tumour subpopulations showed that the clone A responses were within the envelope of additivity for either sequence of application. In contrast, the responses of the clone D tumour subpopulation exhibited a supra-additive response to the combined treatments with the sequence of heat followed by X-irradiation being somewhat more effective than the sequence of X-irradiation followed by heat. These data indicate that the responses of tumour subpopulations obtained from heterogeneous solid tumours to combined modality treatments may vary in an, at present, unpredictable manner.

    Full Text Available We estimated the frequency of anatomic variations in origin of the left coronary artery in a Turkish population by analyzing the angiographic data of 10,042 consecutive adult patients undergoing coronary angiography. Among 10,042 adult patients, 5 (0.04% patients (4 men and 1 woman, age range 40-74, median 58 years old had anomalous origin of the left main coronary artery. The left main coronary artery arose from the right coronary sinus of Valsalva in 2 (0.019% patients (both of them had a retro-aortic course, from above the left coronary sinus of Valsalva in 2 (0.019% patients, and from above the non-coronary (posterior-left coronary commisure in 1 (0.009% patient. Anomalous origin of the left main coronary artery is potentially a serious condition, as it can lead to myocardial infarction and sudden cardiac death under physical exertion. Therefore, greater effort for early detection and surgical repair of this anomaly are warranted. The angiographic recognition of anomalous origin of this vessel may prove useful for physicians dealing with diagnosis and treatment of anomalies of the left main coronary artery.

    In the last few years, forced and unregistered child marriage has widely increased into Turkey. The aim of this study was to test the accuracy of cut-off value of 0.08 by measurement of third molar index (I3M) in assessing legal adult age of 18 years. Digital panoramic images of 293 Turkish children and young adults (165 girls and 128 boys), aged between 14 and 22 years, were analysed. Age distribution gradually decreases as I3M increases in both girls and boys. For girls, the sensitivity was 85.9% (95% CI 77.1-92.8%) and specificity was 100%. The proportion of correctly classified individuals was 92.7%. For boys, the sensitivity was 94.6% (95% CI 88.1-99.8%) and specificity was 100%. The proportion of correctly classified individuals was 97.6%. The cut-off value of 0.08 is a useful method to assess if a subject is older than 18 years of age or not.

    Full Text Available BACKGROUND: STAT3 activation is frequently detected in breast cancer and this pathway has emerged as an attractive molecular target for cancer treatment. Recent experimental evidence suggests ALDH-positive (ALDH(+, or cell surface molecule CD44-positive (CD44(+ but CD24-negative (CD24(- breast cancer cells have cancer stem cell properties. However, the role of STAT3 signaling in ALDH(+ and ALDH(+/CD44(+/CD24(- subpopulations of breast cancer cells is unknown. METHODS AND RESULTS: We examined STAT3 activation in ALDH(+ and ALDH(+/CD44(+/CD24(- subpopulations of breast cancer cells by sorting with flow cytometer. We observed ALDH-positive (ALDH(+ cells expressed higher levels of phosphorylated STAT3 compared to ALDH-negative (ALDH(- cells. There was a significant correlation between the nuclear staining of phosphorylated STAT3 and the expression of ALDH1 in breast cancer tissues. These results suggest that STAT3 is activated in ALDH(+ subpopulations of breast cancer cells. STAT3 inhibitors Stattic and LLL12 inhibited STAT3 phosphorylation, reduced the ALDH(+ subpopulation, inhibited breast cancer stem-like cell viability, and retarded tumorisphere-forming capacity in vitro. Similar inhibition of STAT3 phosphorylation, and breast cancer stem cell viability were observed using STAT3 ShRNA. In addition, LLL12 inhibited STAT3 downstream target gene expression and induced apoptosis in ALDH(+ subpopulations of breast cancer cells. Furthermore, LLL12 inhibited STAT3 phosphorylation and tumor cell proliferation, induced apoptosis, and suppressed tumor growth in xenograft and mammary fat pad mouse models from ALDH(+ breast cancer cells. Similar in vitro and tumor growth in vivo results were obtained when ALDH(+ cells were further selected for the stem cell markers CD44(+ and CD24(-. CONCLUSION: These studies demonstrate an important role for STAT3 signaling in ALDH(+ and ALDH(+/CD44(+/CD24(- subpopulations of breast cancer cells which may have cancer stem

    Full Text Available Abstract Background The complex neuronal circuitry of the dorsal horn of the spinal cord is as yet poorly understood. However, defining the circuits underlying the transmission of information from primary afferents to higher levels is critical to our understanding of sensory processing. In this study, we have examined phosphodiesterase 1C (Pde1c BAC transgenic mice in which a green fluorescent protein (GFP reporter gene reflects Pde1c expression in sensory neuron subpopulations in the dorsal root ganglia and spinal cord. Results Using double labeling immunofluorescence, we demonstrate GFP expression in specific subpopulations of primary sensory neurons and a distinct neuronal expression pattern within the spinal cord dorsal horn. In the dorsal root ganglia, their distribution is restricted to those subpopulations of primary sensory neurons that give rise to unmyelinated C fibers (neurofilament 200 negative. A small proportion of both non-peptidergic (IB4-binding and peptidergic (CGRP immunoreactive subclasses expressed GFP. However, GFP expression was more common in the non-peptidergic than the peptidergic subclass. GFP was also expressed in a subpopulation of the primary sensory neurons immunoreactive for the vanilloid receptor TRPV1 and the ATP-gated ion channel P2X3. In the spinal cord dorsal horn, GFP positive neurons were largely restricted to lamina I and to a lesser extent lamina II, but surprisingly did not coexpress markers for key neuronal populations present in the superficial dorsal horn. Conclusion The expression of GFP in subclasses of nociceptors and also in dorsal horn regions densely innervated by nociceptors suggests that Pde1c marks a unique subpopulation of nociceptive sensory neurons.

    Full Text Available Abstract Background Divergence of bacterial populations into distinct subpopulations is often the result of ecological isolation. While some studies have suggested the existence of Salmonella enterica subsp. enterica subclades, evidence for these subdivisions has been ambiguous. Here we used a comparative genomics approach to define the population structure of Salmonella enterica subsp. enterica, and identify clade-specific genes that may be the result of ecological specialization. Results Multi-locus sequence analysis (MLSA and single nucleotide polymorphisms (SNPs data for 16 newly sequenced and 30 publicly available genomes showed an unambiguous subdivision of S. enterica subsp. enterica into at least two subpopulations, which we refer to as clade A and clade B. Clade B strains contain several clade-specific genes or operons, including a β-glucuronidase operon, a S-fimbrial operon, and cell surface related genes, which strongly suggests niche specialization of this subpopulation. An additional set of 123 isolates was assigned to clades A and B by using qPCR assays targeting subpopulation-specific SNPs and genes of interest. Among 98 serovars examined, approximately 20% belonged to clade B. All clade B isolates contained two pathogenicity related genomic islands, SPI-18 and a cytolethal distending toxin islet; a combination of these two islands was previously thought to be exclusive to serovars Typhi and Paratyphi A. Presence of β-glucuronidase in clade B isolates specifically suggests an adaptation of this clade to the vertebrate gastrointestinal environment. Conclusions S. enterica subsp. enterica consists of at least two subpopulations that differ specifically in genes involved in host and tissue tropism, utilization of host specific carbon and nitrogen sources and are therefore likely to differ in ecology and transmission characteristics.

  10. CCAST: a model-based gating strategy to isolate homogeneous subpopulations in a heterogeneous population of single cells.

    Benedict Anchang

    2014-07-01

    Full Text Available A model-based gating strategy is developed for sorting cells and analyzing populations of single cells. The strategy, named CCAST, for Clustering, Classification and Sorting Tree, identifies a gating strategy for isolating homogeneous subpopulations from a heterogeneous population of single cells using a data-derived decision tree representation that can be applied to cell sorting. Because CCAST does not rely on expert knowledge, it removes human bias and variability when determining the gating strategy. It combines any clustering algorithm with silhouette measures to identify underlying homogeneous subpopulations, then applies recursive partitioning techniques to generate a decision tree that defines the gating strategy. CCAST produces an optimal strategy for cell sorting by automating the selection of gating markers, the corresponding gating thresholds and gating sequence; all of these parameters are typically manually defined. Even though CCAST is optimized for cell sorting, it can be applied for the identification and analysis of homogeneous subpopulations among heterogeneous single cell data. We apply CCAST on single cell data from both breast cancer cell lines and normal human bone marrow. On the SUM159 breast cancer cell line data, CCAST indicates at least five distinct cell states based on two surface markers (CD24 and EPCAM and provides a gating sorting strategy that produces more homogeneous subpopulations than previously reported. When applied to normal bone marrow data, CCAST reveals an efficient strategy for gating T-cells without prior knowledge of the major T-cell subtypes and the markers that best define them. On the normal bone marrow data, CCAST also reveals two major mature B-cell subtypes, namely CD123+ and CD123- cells, which were not revealed by manual gating but show distinct intracellular signaling responses. More generally, the CCAST framework could be used on other biological and non-biological high dimensional data

    The aim of this study was to develop an objective method to determine the incidence of pleiomorphisms and its influence on the distribution of sperm morphometric subpopulations in ejaculates of howling monkeys ( Alouatta caraya) by using a combination of computerized analysis system (ASMA) and principal component analysis (PCA) methods. Ejaculates were collected by electroejaculation methods on a regular basis from five individuals maintained under identical captive environmental, nutritional, and management conditions. Each sperm head was measured for dimensional parameters (Area [ A, (square micrometers)], Perimeter [ P, (micrometers)], Length [ L, (micrometers)], and Width [ W, (micrometers)]) and shape-derived parameters (Ellipticity [( L/ W)], Elongation [( L - W)/( L + W)], and Rugosity [(4л A/ P 2)]). PCA revealed two principal components explaining more than the 96 % of the variance. Clustering methods and discriminant analyzes were performed and seven separate subpopulations were identified. There were differences ( P < 0.001) in the distribution of the seven subpopulations as well as in the incidence of abnormal pleiomorphisms (58.6 %, 49.8 %, 35.1 %, 66.4 %, and 55.1 %, P < 0.05) among the five donors tested. Our results indicated that differences among individuals related to the incidence of pleiomorphisms, and sperm subpopulational structure was not related to the captivity conditions or the sperm collection method, since all individuals were studied under identical conditions. In conclusion, the combination of ASMA and PCA is a useful clinical diagnostic resource for detecting deficiencies in sperm morphology and sperm subpopulations in A. caraya ejaculates that could be used in ex situ conservation programs of threatened species in Alouatta genus or even other endangered neotropical primate species.

    Full Text Available Teacher and student attitudes towards the technology enhanced instruction plays a critical role in determining its effectiveness. The purpose of the study is to examine Turkish and American students’ attitudes and thoughts toward the use of educational technologies in history courses, and to compare the results to determine whether there are any differences between the attitudes of Turkish and American student. This study was conducted with 197 American students from Upper Saint Claire High school in Pittsburgh, PA, and 214 Turkish students from Konya High school who volutered for this study. The required data for this study were gathered by a 26-item technology questionnaire, which included 7 multiple-choice questions and 19 Likert scale questions. This questionnaire was developed to gather data on five different areas of interest: (1 demographic information, (2 participants’ computer- and Internet-usage skills, (3 the level of technology used in history classrooms, (4 participants’ attitudes toward technology-enhanced history education, and (5 participants’ attitudes toward history. Most of the Turkish and American students rated themselves as being very well experienced on the eight computer- and Internet-usage skills targeted in this study. But the comparison of the data indicated that American students have higher computer- and Internet-usage skills than Turkish students do, and this difference is statistically significant (p = 0.001. Most of the Turkish and American students showed positive attitudes on using educational technologies in history classrooms. A majority of the Turkish and American students stated that they would be able to focus and learn better if more technological materials were used in classroom activities, and this, in turn, would increase their academic achievements.

  13. INFLUENCE OF TURKISH BATH CULTURE ON THE DESIGN OF SPA & WELLNESS VENUES

    2009-06-01

    Full Text Available Throughout the history, water has been one of the main determinants of the human lifestyle in every culture. Turkish baths, which are among the most important extant water structures, are the products of a building type that appeared with the merger of Turkish bathing culture with the Anatolian bathing culture. At present, Turkish baths are defined in a different way as the venues for socializing in addition to bathing. In continuous change, modern man desires to reach global health services in the globalizing world in order to both protect his wellness and obtain the most effective treatment. In addition to its physical implications, the concept of wellness also refers to emotional and socio-cultural well-being. This changing paradigm of wellness has created the concept of Spa & wellness. Spa & wellness center is the name given to water therapies that have been applied since the Romans. The main reason of this development and change is the prominence of sauna-vapor-water systems as supporting and complementary elements to medicine and the demands of the users in this regard. The man of the present time desires to reach the scientific and technological developments in modern science not only for health and treatment services, but also for beauty and to “stay young”. This desire has turned health tourism into an important tourism trend in the world. Therefore, spatial formations must be dwelled on for Spa & wellness centers to function properly. This study outlines the influences of traditional Turkish baths on the design of the present time Spa & wellness venues. In order to identify these influences, initially the Turkish bath culture and the interior characteristics of Turkish bath are examined. Then, Spa & wellness concept and design criteria are searched. Finally, in accordance with these examinations, the spatial interactions of the traditional Turkish baths with Spa & wellness centers are evaluated.

    Purpose: In patients with multiple lesions, resistance to cancer treatments and subsequent disease recurrence may be due to heterogeneity of response across lesions. This study aims to identify subpopulations of similarly-responding metastatic prostate cancer lesions in bone using quantitative PET metrics. Methods: Seven metastatic prostate cancer patients treated with AR-directed therapy received pre-treatment and mid-treatment [F-18]NaF PET/CT scans. Images were registered using an articulated CT registration algorithm and transformations were applied to PET segmentations. Midtreatment response was calculated on PET-based texture features. Hierarchical agglomerative clustering was used to form groups of similarly-responding lesions, with the number of natural clusters (K) determined by the inconsistency coefficient. Lesion clustering was performed within each patient, and for the pooled population. The cophenetic coefficient (C) quantified how well the data was clustered. The Jaccard Index (JI) assessed similarity of cluster assignments from patient clustering and from population clustering. Results: 188 lesions in seven patients were identified for analysis (between 6 to 53 lesions per patient). Lesion response was defined as percent change relative to pre-treatment for 23 uncorrelated PET-based feature identifiers. . High response heterogeneity was found across all lesions (i.e. range ΔSUVmax =−95.98% to 775.00%). For intra-patient clustering, K ranged from 1–20. Population-based clustering resulted in 75 clusters, of 1-6 lesions each. Intra-patient clustering resulted in higher quality clusters than population clustering (mean C=0.95, range=0.89 to 1.00). For all patients, cluster assignments from population clustering showed good agreement to intra-patient clustering (mean JI=0.87, range=0.68 to 1.00). Conclusion: Subpopulations of similarly-responding lesions were identified in patients with multiple metastatic lesions. Good agreement was found between

    Full Text Available Background: The effects of demographic factors on a wide range of immunological variables demonstrate the importance of having normative data representative of particular patient population. There was no lymphocyte subpopulation data for Macedonian children and the purpose of this study was to establish such a data. Subject and methods: The study population consists of 87 healthy children. Subjects were grouped into four age categories as follows: group 1 age range 5d-10d (n=15; group 2 age range 1 mo-1 yr (n=18; group 3 age 1yr-2 yr(n=20 and group 4 age 2yr-5 yr(n=34 Monoclonal antibodies labeled with fluorochromes and immunofluorescent microscopy were used to detect cells bearing specific cell markers. Results: The mean lymphocyte cell count gradually fell with increasing age from 6,65x10^9/l in group 1, to 5,67x10^9/l in group 2, 4,55x10^9/l in group 3, and to 4,14x10^9/l in group 4. Absolute values of CD3, CD4 and CD20 positive cells decreased gradually with age. Significant differences in mean absolute values were observed for absolute lymphocyte counts between groups 1/2 and 1/4 (P<0,01 and groups 2/4(P<0,05; for CD3 positive lymphocytes between groups 1/3(P<0,05 and 1/4(P<0,01; for CD4 positive lymphocytes between groups 1/3 (P<0,05 and 1/4(P<0,01 and for CD20 positive lymphocytes between groups 1/3 and 3/4(P<0,05 and groups 1/4 (P<0,01. Significant difference for CD4/CD8 ratio and for percentage values of different lymphocyte subpopulations between the different age groups was not found. Conclusion: This data may serve as a reference range for studies of Macedonian pediatric subjects.

  17. Development and Identification of a Novel Subpopulation of Human Neutrophil-derived Giant Phagocytes In Vitro

    Neutrophils (PMN) are best known for their phagocytic functions against invading pathogens and microorganisms. They have the shortest half-life amongst leukocytes and in their non-activated state are constitutively committed to apoptosis. When recruited to inflammatory sites to resolve inflammation, they produce an array of cytotoxic molecules with potent antimicrobial killing. Yet, when these powerful cytotoxic molecules are released in an uncontrolled manner they can damage surrounding tissues. In recent years however, neutrophil versatility is increasingly evidenced, by demonstrating plasticity and immunoregulatory functions. We have recently identified a new neutrophil-derived subpopulation, which develops spontaneously in standard culture conditions without the addition of cytokines/growth factors such as granulocyte colony-stimulating factor (GM-CSF)/interleukin (IL)-4. Their phagocytic abilities of neutrophil remnants largely contribute to increase their size immensely; therefore they were termed giant phagocytes (Gϕ). Unlike neutrophils, Gϕ are long lived in culture. They express the cluster of differentiation (CD) neutrophil markers CD66b/CD63/CD15/CD11b/myeloperoxidase (MPO)/neutrophil elastase (NE), and are devoid of the monocytic lineage markers CD14/CD16/CD163 and the dendritic CD1c/CD141 markers. They also take-up latex and zymosan, and respond by oxidative burst to stimulation with opsonized-zymosan and PMA. Gϕ also express the scavenger receptors CD68/CD36, and unlike neutrophils, internalize oxidized-low density lipoprotein (oxLDL). Moreover, unlike fresh neutrophils, or cultured monocytes, they respond to oxLDL uptake by increased reactive oxygen species (ROS) production. Additionally, these phagocytes contain microtubule-associated protein-1 light chain 3B (LC3B) coated vacuoles, indicating the activation of autophagy. Using specific inhibitors it is evident that both phagocytosis and autophagy are prerequisites for their development and

    Full Text Available The concept of mother tongue in foreign countries refers to the native language that the immigrants bring to and speak in foreign countries. This language is usually used by immigrant groups and passed on to next generations through speaking in the immigrant families. Within the context of modern history of immigration, it is observed that the immigrants make efforts to transfer the standard form of their language (including writing from generation to generation and to establish schools and other units for that purpose. Since the mid-twentieth-century, formal education institutions of Western countries that allow immigration have actively been interested in the teaching of mother tongue of immigrants. The overall objective of this paper is to analyze the structure of Turkish courses in the Federal Republic of Germany and Turkish students’ views on these courses. Turkish -as a language spoken by 5 million people in many countries of Western Europe- occupies the first rank among the minority languages; unfortunately, it does not have the deserved attention. In the European Union countries, in line with minority rights, more than two million children and young people in schools are supposed to receive a good education in Turkish language; nevertheless, there exists only limited facilities in most of these countries. As a relational survey method, this research is based on the analysis of Turkish immigrant students' perceptions/views on the Turkish language with respect to some variables. It includes immigrant students of Turkish origin (students in the age group of 11-18 years, of the 5th-12th grade who live in various states of Germany (Baden-Wurtemberg, Lower Saxony, Bremen, Hamburg and Berlin. The sample consists of 580 students (of the same age and grade selected through random cluster sampling approach. In this research, two questionnaires are used by the researcher in order to determine some demographic characteristics and perceptions

    Full Text Available Even though definitions about translation have changed with developing and changing societies and disc overy of new translation theories, the translation in general refers to transfer of a written text in a language to another language while preserving its semantic content and formal structure in a definite platform. Beyond being a linguistic phenomenon of translation, it is now recognized by many theorists that translation is a complex process that can change the history. For this reason, the translation has an important mission in the social relations and penetrates directly into the target culture because it is an interlingual and intercultural transfer. Accordingly, it gains an important place in this culture. In this context, the Arabic culture, through the translations from Arabic into Turkish, has gained a place in Turkish society and thereby had oppor tunity to introduce its own culture. The aim of this study is to determine cultural transfer in translations made from Arabic to Turkish. In this context, firstly, definition of translation, its scope, fuction and translation - culture transfer relationship was clarified. The study ended with examples through some literary works translated from Arabic to Turkish. This study is a survey research. Firstly, some theoretical information was obtained by reviewing the literature. Later, the relationship between tra nslation - culture transfer was found via examples of translated works from Arabic to Turkish. In this study, only translations of literary works that belong to modern period Arabic literature were taken into consideration, excluding classical period or reli gious literature translations.

    Full Text Available The current study explored the psychometric properties of the newly designed Turkish version of the Cognitive Test Anxiety Scale–Revised (CTAR. Results of an exploratory factor analysis revealed an unidimensional structure consistent with the conceptualized nature of cognitive test anxiety and previous examinations of the English version of the CTAR. Examination of the factor loadings revealed two items that were weakly related to the test anxiety construct and as such were prime candidates for removal. Confirmatory factor analyses were conducted to compare model fit for the 25- and 23-item version of the measure. Results indicated that the 23-item version of the measure provided a better fit to the data which support the removal of the problematic items in the Turkish version of the CTAR. Additional analyses demonstrated the internal consistency, test–retest reliability, concurrent validity, and gender equivalence for responses offered on the Turkish version of the measure. Results of the analysis revealed a 23-item Turkish version of the T-CTAR is a valid and reliable measure of cognitive test anxiety for use among Turkish students.

    Full Text Available Many studies have focused on climate change policies and action at the national level, but few have studied policies and action at the city level, especially cities in emerging economies. To address this gap, the present study analyzes the management strategies globally leading cities have developed to address climate change and related issues and compares them with the city strategies of one rapidly urbanizing emerging economy, Turkey. In the analysis, the strategic plans of five leading global cities are compared with those of sixteen Turkish cities. While the leading global cities have specific managerial approaches to mitigate climate change, none of the Turkish cities exhibits any comprehensive approach. Furthermore, while leading global cities modify urban services to reduce greenhouse gas (GHG emissions, few Turkish cities adjust any services to address this challenge. Some Turkish cities propose an increased use of renewable energy sources and modification in their transportation system, but the focus in these plans is the current daily needs of their inhabitants. The findings of this study suggest several climate change strategies both for Turkish cities and cities in other developing countries.

    Full Text Available Head spinning pace of change and development in information and technology has not yet discredited coursebooks as the major classroom tool and equipment. Coursebooks, as they have always been, are still the primary source and tool of teaching and learning process. As with the mainstream education, well-prepared coursebooks and texts are also a necessity for a high-quality Turkish course within distance education. Distance education is a legitimate education activity providing opportunities for students, teachers, and materials located in different places to meet. All the responsibility of teaching within distance education falls onto the course material. Among the printed materials, it is almost solely the coursebook and class notes that shoulder this responsibility. Texts within the current coursebooks should be analyzed in order to depict the current status, which will help increase the quality of distance education. Designed on the basis of this need, this study is expected to contribute to teaching Turkish through a realistic analysis of the texts in Turkish coursebooks studied at Open Education Secondary School (5th, 6th, 7th, and 8th grades. Bearing a descriptive research design, this paper aims to examine and assess the texts in Turkish coursebooks used in Open Education Secondary School in terms of genre, topic, and moral lessons. Research data has been collected through document analysis, one of the qualitative research methods. Each of 96 texts found in Turkish coursebooks were meticulously analyzed, and findings are presented in frequency tables.
