Greek Cypriot attitudes toward Turkish Cypriots and Turkish immigrants.  

PubMed

The authors examined the attitudes of 106 Greek Cypriots toward Turkish Cypriots and Turkish immigrants on Cyprus. The authors examined Greek Cypriot attitudes, willingness to cohabit with Turkish Cypriots and Turkish immigrants, and the reasons behind their attitudes in terms of their social-identity perceptions, victimization experiences, and human-rights concerns. A series of repeated measures analyses of variance showed that Greek Cypriots were more willing to cohabit with and had less negative attitudes toward Turkish Cypriots than they were with and toward Turkish immigrants. Women felt more victimized by Turkish Cypriots and Turkish immigrants than did men. Perceived differences in social identity predicted unwillingness to cohabit with Turkish Cypriots. Feelings of victimization predicted negative attitudes toward Turkish Cypriots. Differences in social identity and victimization experiences predicted unwillingness to cohabit with Turkish immigrants. Differences in social identity predicted negative attitudes toward Turkish immigrants. The authors discussed the findings in terms of support for realistic group conflict theories of attitudes and their implications for the coexistence of these ethnic groups in Cyprus and of other ethnic groups in multicultural societies.

Bulgarian Turkish emigration and return.  

PubMed

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 differences. The unifying factor was the Islamic religion. For those returning to Bulgaria, the change in regime meant the government worked to solve the emigrants' housing problems and teaching Turkish in primary and secondary schools. The result of this massive migration has been a change in the demographics and social structure of Bulgaria, and the realization that forceful migration is inefficient in solving problems.

Religiosity, Values, and Acculturation: A Study of Turkish, Turkish Belgian, and Belgian Adolescents  

PubMed Central

We address the understudied religious dimension of acculturation in acculturating adolescents who combine a religious Islamic heritage with a secularized Christian mainstream culture. The religiosity of 197 Turkish Belgian adolescents was compared with that of 366 agemates in Turkey (the heritage culture) and 203 in Belgium (the mainstream culture) and related to cultural values, acculturation orientations, and ethnic identification. Belgian adolescents showed lower and declining religiosity with age, whereas Turkish and Turkish Belgian adolescents were more religious regardless of age. Acculturating adolescents reaffirmed religion as compared with monocultural adolescents in Turkey. Religious reaffirmation was related to cultural values of interdependence, heritage culture maintenance, and ethnic identification. PMID:23155300

PubMed Central

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

The Middle East: a new destination for Turkish labour migration.

The shifts in migration experienced by Turkish emigrants are discussed starting with the large-scale emigration to Western Europe in the early 1960s. Official figures illustrate that since the 1970s the major current has been toward the Middle East and North Africa, specifically to Libya, Saudi Arabia, and Iraq. Socioeconomic and political factors influencing Turkish migration are discussed. The earlier migrants to Western Europe and later migrants to the Middle East and North Africa are compared on the bases of sex ratio, settlement and duration of stay, remittances, motives, and individual migrants versus organized groups of workers. Turkish migration to Australia is also discussed. PMID:12314523

Illness causal beliefs in Turkish immigrants  

PubMed Central

Background People hold a wide variety of beliefs concerning the causes of illness. Such beliefs vary across cultures and, among immigrants, may be influenced by many factors, including level of acculturation, gender, level of education, and experience of illness and treatment. This study examines illness causal beliefs in Turkish-immigrants in Australia. Methods Causal beliefs about somatic and mental illness were examined in a sample of 444 members of the Turkish population of Melbourne. The socio-demographic characteristics of the sample were broadly similar to those of the Melbourne Turkish community. Five issues were examined: the structure of causal beliefs; the relative frequency of natural, supernatural and metaphysical beliefs; ascription of somatic, mental, or both somatic and mental conditions to the various causes; the correlations of belief types with socio-demographic, modernizing and acculturation variables; and the relationship between causal beliefs and current illness. Results Principal components analysis revealed two broad factors, accounting for 58 percent of the variation in scores on illness belief scales, distinctly interpretable as natural and supernatural beliefs. Second, beliefs in natural causes were more frequent than beliefs in supernatural causes. Third, some causal beliefs were commonly linked to both somatic and mental conditions while others were regarded as more specific to either somatic or mental disorders. Last, there was a range of correlations between endorsement of belief types and factors defining heterogeneity within the community, including with demographic factors, indicators of modernizing and acculturative processes, and the current presence of illness. Conclusion Results supported the classification of causal beliefs proposed by Murdock, Wilson & Frederick, with a division into natural and supernatural causes. While belief in natural causes is more common, belief in supernatural causes persists despite modernizing and acculturative influences. Different types of causal beliefs are held in relation to somatic or mental illness, and a variety of apparently logically incompatible beliefs may be concurrently held. Illness causal beliefs are dynamic and are related to demographic, modernizing, and acculturative factors, and to the current presence of illness. Any assumption of uniformity of illness causal beliefs within a community, even one that is relatively culturally homogeneous, is likely to be misleading. A better understanding of the diversity, and determinants, of illness causal beliefs can be of value in improving our understanding of illness experience, the clinical process, and in developing more effective health services and population health strategies.

Climate Change Impacts on Turkish Vegetation  

NASA Astrophysics Data System (ADS)

The Mediterranean has been identified as a potentially vulnerable hotspot under climate change. In Turkey, climate change projections consistently predict large temperature rises over the 21st century. With 9% of GDP and 25% of employment coming from agriculture, climate change has the potential to significantly affect both the Turkish economy and living standards. Relatively little work has been undertaken to estimate the effects and risks of climate change in Turkey, and many European studies cover do not include the whole of Turkey in their domain and so are of limited use for policy-makers. The Dynamic Global Vegetation Model LPJ-GUESS was parametrised to represent Turkish vegetation. Climate forcings were derived by interpolating meteorological data from over 600 stations from 1975-2010 to a 1km resolution. Soil depth and soil texture data from field measurements were also interpolated to a 1km grid. The model was benchmarked against vegetation type and remotely sensed biomass and tree cover data. Future climate conditions were calculated using the outputs from a set of regional model simulations. In particular the HadRM3P regional climate model was used to downscale five members of a perturbed physics ensemble of global climate projections obtained using HadCM3 general circulation model and the SRES A1B scenario. A delta change factor approach was then used in conjunction with the observed climate data to assess the impact on vegetation structure and ecological processes to the year 2100 using LPJ-GUESS. The resulting changes to productivity, vegetation structure and hydrology are discussed. Eventually these results will be combined with complementary studies concerning wildfire and erosion to produce a risk map for informing policy-makers.

Trace elements in obese Turkish children.  

PubMed

The quality of the diet of obese children is poor. Eating habits may alter micronutrient status in obese patients. In this study, we determined the serum levels of selenium, zinc, vanadium, molybdenum, iron, copper, beryllium, boron, chromium, manganese, cobalt, silver, barium, aluminum, nickel, cadmium, mercury, and lead in obese Turkish children. Thirty-four obese and 33 healthy control subjects were enrolled in the study. Serum vanadium and cobalt levels of obese children were significantly lower than those of the control group (0.244 ± 0.0179 vs. 0.261 ± 0.012 ?g/l, p < 0.001, and 0.14 ± 0.13 vs. 0.24 ± 0.15 ?g/l, p = 0.011, respectively). There was no significant difference between groups regarding the other serum trace element levels. In conclusion, there may be alterations in the serum levels of trace elements in obese children and these alterations may have a role in the pathogenesis of obesity. PMID:20957449

Turkish children use morphosyntactic bootstrapping in interpreting verb meaning.  

PubMed

How might syntactic bootstrapping apply in Turkish, which employs inflectional morphology to indicate grammatical relations and allows argument ellipsis? We investigated whether Turkish speakers interpret constructions differently depending on the number of NPs in the sentence, the presence of accusative case marking and the causative morpheme. Data were collected from 60 child speakers and 16 adults. In an adaptation of Naigles, Gleitman & Gleitman (1993), the participants acted out sentences (6 transitive and 6 intransitive verbs in four different frames). The enactments were coded for causativity. Causative enactments increased in two-argument frames and decreased in one-argument frames, albeit to a lesser extent than previously found in English. This effect was generally stronger in children than in adults. Causative enactments increased when the accusative case marker was present. The causative morpheme yielded no increase in causative enactments. These findings highlight roles for morphological and syntactic cues in verb learning by Turkish children. PMID:18416861

The experiences of involuntarily childless Turkish immigrants in the Netherlands.  

PubMed

The consequences of involuntary childlessness are influenced by culture in several ways. In this study we explored the experiences and responses of infertile Turkish immigrants in the Netherlands. Twenty in-depth interviews were conducted with involuntarily childless Turkish immigrants in the Netherlands (11 couples and 9 women). Interviews were transcribed verbatim and were analyzed using interpretative phenomenological analysis (IPA). The respondents' experiences were clustered around six superordinate themes: effects on self; effects on the relationship with the partner; effects on the relationship with others; disclosure; coping; and the future. Most transcripts revealed that involuntary childlessness has a profound negative influence on multiple aspects of the lives of the respondents. Strong pronatalist ideology, misconceptions about infertility and treatment, and migration-related aspects such as language difficulties, appear to play a role in the negative experiences of Turkish immigrants. Respondents reported several ways of coping (to some extent) with these negative experiences. PMID:19270194

Low back pain and lumbar angles in Turkish coal miners  

SciTech Connect

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.

Anthropometric Studies on the Turkish Population - A Historical Review

A historical review of anthropometric studies conducted on Turkish children and adults is presented. In view of observed differences in growth status between children of different societies, the need for local reference standards and the methodology to be used for such studies have been stressed. The importance of local studies in reflecting the state of health and nutrition both in children and adults has also been mentioned. While a number of studies in children cited in this paper are designed to compare the growth of children from different socioeconomic levels, other studies aim to establish local reference data for Turkish children. While the historical studies in adults aim to define racial characteristics, the more recent studies aim to bring out nutritional characteristics with emphasis on increasing frequency of obesity.

Applicability of the Demirjian method for dental age estimation in western Turkish children.  

PubMed

Abstract Objective. The aim of this study was to examine whether the Demirjian method would be appropriate for estimation of the dental age of western Turkish children. Materials and methods. This study comprised 635 Turkish children (age = 7-16 years) from the western Aegean region who were chosen on the basis of radiological evidence from digital orthopantomograms. Their dental maturity was evaluated according to the stages proposed by Demirjian. A paired t-test was used for statistical analysis. Results. The mean difference between the chronological and dental ages ranged from 0.10-0.76 years for males and from 0.28-0.87 years for females. Conclusion. The applicability of the Demirjian method is not suitable for western Turkish children and western Turkish children have a lower degree of dental maturity than that observed in the eastern, northeastern and northern Turkish subjects.

Comparison of soft tissue cephalometric norms between Turkish and European-American adults.  

PubMed

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. PMID:23533362

Taking it to the grave: gender, cultural capital, and ethnicity in Turkish death announcements.  

PubMed

Popularly considered a great equalizer, death and the rituals around it nevertheless accentuate social distinctions. The present study focuses on a sample (N = 2554) of death announcements in a major Turkish daily newspaper (Hürriyet) from 1970 to 2006. Out of the liminal position of Turkish death announcements between obituaries and death notices emerges a large decentralized collection of private decisions responding to death, reflecting attitudes toward gender, ethnic/religious minority status and cultural capital, and echoing the aggregate efforts of privileged groups to maintain a particular self-image. Class closures lead to openings for traditionally under-represented minorities, such as Jewish Turkish citizens and citizens of Greek or Armenian origin. Results reveal that signs of status and power in announcements are largely monopolized by men of Turkish-Muslim origins. Although the changes in the genre-characteristics of death announcements are slow, they correspond to major turning points in Turkish social history. PMID:20222236

The validity and reliability of the Turkish version of the Revised Fibromyalgia Impact Questionnaire.  

PubMed

The Revised Fibromyalgia Impact Questionnaire (FIQR) attempts to address the limitations of the Fibromyalgia Impact Questionnaire (FIQ). As there is no Turkish version of the FIQR available, we aimed to investigate the validity and reliability of a Turkish translation of the FIQR in Turkish female fibromyalgia (FM) patients. After translating the FIQR into Turkish, it was administered to 87 female patients with FM. All of the patients filled out the questionnaire together with a Turkish version of the FIQ, hospital anxiety and depression scales (HADS), short form-36 (SF-36). The tender-point count (TPC) was also calculated from tender points identified by thumb palpation. One week later, FM patients filled out the Turkish FIQR at their second visit. The test-retest reliability of the Turkish FIQR questions ranged from 0.714 to 0.898. The test and retest reliability of total FIQR score was 0.835. Cronbach's alpha was 0.89 for FIQR visit 1 (the first assessment) and 0.91 for FIQR visit 2 (the second assessment), indicating acceptable levels of internal consistency for both assessments. The total scores of the FIQR and FIQ were significantly correlated (r?=?0.87, P?Turkish FIQR is a reliable and valid instrument for measuring health status in FM, showing sufficient reliability and construct validity. It may be utilized for both clinical practice and research use in the Turkish-speaking population in place of FIQ, since its Turkish version has problems in the wording, omissions, concepts, and scoring from the original FIQ.

Erionite exposure in North Dakota and Turkish villages with mesothelioma  

PubMed Central

Exposure to erionite, an asbestos-like mineral, causes unprecedented rates of malignant mesothelioma (MM) mortality in some Turkish villages. Erionite deposits are present in at least 12 US states. We investigated whether increased urban development has led to erionite exposure in the United States and after preliminary exploration, focused our studies on Dunn County, North Dakota (ND). In Dunn County, ND, we discovered that over the past three decades, more than 300 miles of roads were surfaced with erionite-containing gravel. To determine potential health implications, we compared erionite from the Turkish villages to that from ND. Our study evaluated airborne point exposure concentrations, examined the physical and chemical properties of erionite, and examined the hallmarks of mesothelial cell transformation in vitro and in vivo. Airborne erionite concentrations measured in ND along roadsides, indoors, and inside vehicles, including school buses, equaled or exceeded concentrations in Boyali, where 6.25% of all deaths are caused by MM. With the exception of outdoor samples along roadsides, ND concentrations were lower than those measured in Turkish villages with MM mortality ranging from 20 to 50%. The physical and chemical properties of erionite from Turkey and ND are very similar and they showed identical biological activities. Considering the known 30- to 60-y latency for MM development, there is reason for concern for increased risk in ND in the future. Our findings indicate that implementation of novel preventive and early detection programs in ND and other erionite-rich areas of the United States, similar to efforts currently being undertaken in Turkey, is warranted.

Italian contributions to Turkish paediatrics during the Ottoman Empire.  

PubMed

The Ottoman Empire maintained close relations with the neighbouring Italian city states in the 16th and 17th century. Yacub Pasha (1425-1481), personal physician of Mehmed II the Conqueror, was an Italian Jew who advanced to the title of pasha and vizier. Domenico Hierosolimitano (ca. 1552-1622), the third physician to Sultan Murad III, was a Jerusalemite rabbi. His book is an important source about everyday life and medical practice in Istanbul at the time. Nuh bin Abd al-Mennab (1627-1707), also of Italian stock, was the Chief Physician of the Ottoman Empire, who translated a pharmacopoeia into Turkish. In the same century, two Italians, Israel Conegliano (Conian) and Tobia Cohen became private physicians to leading Ottoman pashas and the Grand Vizier. A. Vuccino (1829-1893) and Antoine Calleja Pasha (1806-1893) taught at the Istanbul Medical School. Italy was a favoured country for medical education during the early period of Ottoman westernisation. Sanizade Mehmet Ataullah Efendi (1771-1826) translated the first medical book printed in the Ottoman Empire from Italian into Turkish. Mustafa Behcet Efendi (1774-1833), chief physician to the Sultan and the founder of the first western medical school in Turkey, translated several medical books from Italian into Turkish. The first printed pharmacopeia in the Ottoman Empire was also originally Italian In the 19th century, Edouard Ottoni and his son Giuseppe Ottoni were well-known military pharmacists, both under the name of Faik Pasha. Probably the most influential physician of Italian origin was Giovanni Battista Violi (1849-1928), who had practiced paediatrics in Turkey for more than fifty years. Violi was the founder of the first children's hospital, the first vaccine institute, and the first paediatric journal in the Ottoman Empire. PMID:24304113

The status of depression and anxiety in infertile Turkish couples  

PubMed Central

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.

Prevalence of celiac disease in Turkish children with autoimmune thyroiditis.  

PubMed

The close association between celiac disease (CD) and autoimmune disorders is well documented in adult and pediatric patients. The aim of this study is to determine the prevalence of CD in Turkish children with autoimmune thyroiditis (AT). Sera from 101 children with AT (11 boys and 90 girls, from 2 to 18 years of age; mean age 12.28 +/- 3.26 years) and 103 healthy children (46 boys and 57 girls, from 3.5 to 17 years of age; mean age 12.18 +/- 3.11 years) were screened for CD using the IgA anti-tissue transglutaminase (IgA anti-tTG) antibody and total serum IgA. Small intestinal biopsy was offered to all antibody-positive patients. IgA anti-tTG was positive in eight children (7.9%) with AT. None of the serum samples of healthy children were positive for IgA anti-tTG antibody. Selective IgA deficiency was not detected in patients or controls. Intestinal biopsy was accepted by seven patients. In five patients (4.9%), subtotal villous atrophy was found. These findings indicate that the prevalence of CD is higher in Turkish children with AT than in healthy controls. Routine screening for CD should be performed in children with AT. PMID:18716873

Hepatoprotective effects of Turkish folk remedies on experimental liver injury.  

PubMed

Seven plants which are used in Turkish folk medicine were studied for possible hepatoprotective effects. These plants are Carduus acanthoides and C. nutans (Asteraceae), Cichorium intybus (Asteraceae), Fumaria asepalae and F. vailantii (Fumariaceae), Gentiana olivieri (Gentianaceae) and Plantago lanceolata (Plantaginaceae). Stems, bracts and receptaculum of Cynara scolymus were used as natural reference drugs. Effects of the ethanolic extracts were studied using the carbon tetrachloride-induced hepatotoxicity model in rats. The extracts of F. vailantii and G. olivieri significantly prevented the elevation of plasma and hepatic malondialdehyde formation (evidence of lipid peroxidation) as well as enzyme levels (AST and ALT) in acute liver injury, which might be ascribed to their potent hepatoprotective activity. Liver sections were also studied histopathologically to confirm the biochemical results. PMID:11025147

HLA types in Turkish children with celiac disease.  

PubMed

The aim of this study was to assess the distribution of human leukocyte antigen (HLA) groups in Turkish children with celiac disease (CD) and to investigate the association of HLA types and clinical manifestations of CD. Seventy-five children with CD were evaluated in two groups: Group I consisted of 45 classical celiac patients (15 males, 6.7+/-3.8 years); Group II consisted of 30 atypical celiac patients (9 males, 9.3+/-4.3 years). The control group consisted of 100 healthy renal transplantation donors. HLA typing was made serologically using standard lymphocytotoxicity techniques. HLA A29, B51, CW5, DR14, DR16, and DQ1 were the most common antigens in the control group. Frequency of HLA B13, CW7, B8, DR7, DR17 and DQ2 was higher in CD patients than in the control group (p<0.005, <0.05, <0.001, <0.001 and <0.001, respectively). The relative risks for HLA DQ2, B8, DR17 and B13 were 14.9, 13.6, 7.1 and 3.6, respectively. Frequency of HLA B35, DR11 and DQ7 was higher in classical CD than atypical CD, while a positive association was found between HLA B8 and atypical CD. A positive association was found between HLA B13, CW7 and DR17 in Turkish celiac patients in addition to HLA B8, DR7 and DQ2. This study also suggested that a correlation may exist between genotype and clinical manifestations. PMID:19227412

Ethnopharmacy of Turkish-speaking Cypriots in Greater London.  

PubMed

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.

Turkish women’s opinions about cesarean delivery  

PubMed Central

Objective: This study explores the opinions of the Turkish women about cesarean delivery and the reasons and factors affecting their preference for it. Methods: This is a descriptive study conducted at Maternity Hospitals in Yozgat, Turkey. A total of 423 women who were on the first cesarean day participated in the study. Data were collected through a questionnaire form administered in the form of a face-to-face interview. Pearson Chi-Square test and logistic regression analyses were used for the statistical analyses. Results: The findings of the study revealed that 13 percent of the participating women reported that the ideal mode of delivery was cesarean delivery while a great majority (87%) opted for vaginal delivery. About 53% of them stated that they would prefer cesarean section for their next delivery while 47% reported that they would choose vaginal delivery . It was observed that 72.1% of participants were satisfied with cesarean delivery; 44.4% of the women were found to prefer cesarean delivery due to labor pain and fear. Conclusion: It was determined that nearly half of the women preferred cesarean delivery due to labor pain and fear despite the fact that they believe that the ideal mode of delivery is vaginal delivery.

Prevalence of Celiac Disease in Turkish Children with Idiopathic Epilepsy  

PubMed Central

Objective: This study has examined the prevalence of celiac disease in Turkish children with idiopathic epilepsy. Methods: Children with idiopathic epilepsy were screened for celiac disease using the IgA anti-tissue transglutaminase antibody and compared with the healthy control group in order to find the association of celiac disease (CD) with idiopathic epilepsy. Upper gastrointestinal endoscopy and small intestinal biopsies were offered to all antibody-positive patients. Findings : A total of 214 children with the diagnosis of idiopathic epilepsy and 166 healthy children as control group were studied. Of the patients recruited, 55.1% had generalized epilepsy, and 44.9% had partial epilepsy. In 33 patients with partial epilepsy, electroclinical features were consistent with a diagnosis of childhood partial epilepsy with occipital paroxysms (CPEO). Two of 33 patients with CPEO had positive IgA anti-tissue transglutaminase antibodies in serology. Pathological examination of small intestinal biopsy specimens showed total villous atrophy in both of them. The prevalence of celiac disease among children with idiopathic epilepsy and CPEO was 0.9% and 6%, respectively. Conclusion: The results of the present study revealed that prevalence of CD is increased in children with epilepsy. On the other hand, as high as 6% prevalence of CD among patients with CPEO found in this study should be kept in mind and the clinicians should be aware of this association.

Facial soft tissue thickness database for craniofacial reconstruction in the Turkish adult population.  

PubMed

320 Turkish adults (160 men, 160 women) who had undergone brain CT in the radiology clinic and showed no sign of maxillofacial pathology were analyzed in order to create a facial soft-tissue thickness database of the Turkish adult population. The soft-tissue thicknesses were measured at 31 landmarks, 10 midline and 21 bilateral anatomical landmarks. Average thickness values for each landmark as well as the standard deviation and range classified according to gender and age are reported. The differences of these mean values related to age and sexes were calculated. The values were then statistically compared to the findings of the European and Korean adults. Overall, the soft-tissue thickness measurements obtained in this study can be used as a database for the forensic craniofacial reconstruction of Turkish adult faces. PMID:25023216

Analysis of physical activity and acculturation among Turkish migrants in Germany and England (.).  

PubMed

Recent literature shows that migrant populations in Western countries are generally less physically active than their host populations. The purpose of the present study was to expand research investigating associations between physical activity (PA) and acculturation and their relationship with several socio-demographic factors among Turkish migrants in Germany and England. The sample consisted of 521 Turkish migrants. Migrant generation, length of residence, and language proficiency were used as indicators of acculturation. Acculturation was not associated with PA among migrants in Germany and England. PA of migrants was significantly associated with migrant's host country, age, sex, marital status, and education. The total PA of migrants in Germany was higher than that of migrants in England; the large majority of females in both Germany and England had low PA, whereas most males had moderate PA. Seemingly, PA in Turkish migrant populations will not necessarily increase as a result of greater acculturation to the host society. PMID:25387040

Impacts of Earthquake Aftermath on Indoor Carbon Monoxide Levels in Turkish Coffeehouses Environment in Duzce, Turkey  

PubMed Central

Background: In 1999, Duzce suffered two consecutive devastating earthquakes above magnitude 7 in August and November. In the present study, we aimed to evaluate the indoor air quality of coffeehouses by determining carbon monoxide (CO) levels and their contributing factors in coffeehouses built before and after the earthquake. Methods: We conducted our study in 76 Turkish coffeehouses in Duzce in winter (November 2007–March 2008) during rush hours (18:00–23:00). The Turkish coffeehouses included in the study were evaluated under four categories based on smoking status and construction date. The characteristics of the coffeehouses, such as their CO levels and temperatures both indoors and outdoors, were all measured. These analyses were carried out with the SPSS 15.0 program. Results: The CO levels in Turkish coffeehouses were above the values indicated as being safe by the WHO. While stoves and cooking equipment were determined to contribute to indoor CO levels, cigarettes were found to be the main source. Indoor CO levels at second hour were very strongly correlated (r: 0.84, P<0.001) (r: 0.91, P<0.001) with indoor CO levels at initial and first hour as well as with smoking status (r: 0.69, P<0.001); they were also moderately correlated with the room volume (r: 0.34, P<0.001) and construction materials (r: 0.31, P<0.001) of the coffeehouse. Conclusion: Elevated CO levels in Turkish coffeehouses indicate the possible presence of other pollutants, particularly when the main source is smoking. In such cases, both individuals and the whole of society are affected negatively in many ways. Therefore, smoking should be prohibited by law in Turkish coffeehouses and national awareness programs should be developed based on peoples’ lifestyles. Moreover, the standards for construction and management of Turkish coffeehouses should be improved as well. PMID:23113122

The researchers studying Seljuq, Begliq and Ottoman periods of Turkish history extending into Central Asia had many difficulties in reaching archival sources until the disintegration of the Soviet Union. Following the end of the Iron Curtain period, formal and cultural relations between Turkic republics of the region with Turkey enabled researchers to establish sincere and close professional and individual relations, too. In this essay A.H. Bayat presents heartily his translation of an Uzbek text on Central Asian Turkish medicine written by H. Hikmetullaev and N. Cabbarow. PMID:11625067

Cancer patterns among children of Turkish descent in Germany: A study at the German Childhood Cancer Registry  

PubMed Central

Background Cancer risks of migrants might differ from risks of the indigenous population due to differences in socioeconomic status, life style, or genetic factors. The aim of this study was to investigate cancer patterns among children of Turkish descent in Germany. Methods We identified cases with Turkish names (as a proxy of Turkish descent) among the 37,259 cases of childhood cancer registered in the German Childhood Cancer Registry (GCCR) during 1980–2005. As it is not possible to obtain reference population data for children of Turkish descent, the distribution of cancer diagnoses was compared between cases of Turkish descent and all remaining (mainly German) cases in the registry, using proportional cancer incidence ratios (PCIRs). Results The overall distribution of cancer diagnoses was similar in the two groups. The PCIRs in three diagnosis groups were increased for cases of Turkish descent: acute non-lymphocytic leukaemia (PCIR 1.23; CI (95%) 1.02–1.47), Hodgkin's disease (1.34; 1.13–1.59) and Non-Hodgkin/Burkitt lymphoma (1.19; 1.02–1.39). Age, sex, and period of diagnosis showed no influence on the distribution of diagnoses. Conclusion No major differences were found in cancer patterns among cases of Turkish descent compared to all other cases in the GCCR. Slightly higher proportions of systemic malignant diseases indicate that analytical studies involving migrants may help investigating the causes of such cancers. PMID:18462495

The etiological features of anterior uveitis in a Turkish population  

PubMed Central

Purpose To identify any patterns in the cause of anterior uveitis in a Turkish population and compare them with results from previous studies. Methods The clinical records of 75 patients between January 2009 and January 2010 were retrospectively analyzed and classified as anterior uveitis according to Standardization of Uveitis Nomenclature criteria. Complete blood count, sedimentation rate, chest radiography, purified protein derivative skin test, and venereal disease research laboratory test were done on all patients. Additional serologic and radiographic tests were performed when indicated. Results Forty-one (54.6%) were male and 34 (45.3%) were female patients. The mean age at presentation was 39.1 ± 12.6 years. Fifty-six (74.6%) had unilateral and 19 (25.3%) had bilateral disease at presentation. A specific diagnosis was able to be established in 54 (72%) patients. The most common diagnoses were anterior uveitis associated with human leukocyte antigen B27 (14.6%) and Fuchs uveitis syndrome (14.6%). The second most common diagnosis was uveitis associated with herpes simplex virus (13.3%), followed by Behcet’s uveitis (6.6%). Systemic disease associations were noted in 15 (20%) patients, and the most commonly associated systemic disease was Behcet’s disease (6.6%). Conclusion Fuchs uveitis syndrome and anterior uveitis associated with human leukocyte antigen B27 were the most common form of anterior uveitis in this study. Using a systematic approach, a diagnosis was able to be established in 72% of the anterior uveitis cases. PMID:22701312

Acupuncture points in the book of ?erefeddin Sabuncuo?lu, a 15th century Turkish physician.  

PubMed

?erefeddin Sabuncuo?lu (1385-1468?), the author of Cerrahiyetü'l-Haniyye (Imperial Surgery), was a distinguished Ottoman Turkish surgeon. The first illustrated Turkish surgical textbook, Cerrahiyetü'l-Haniyye consisted of three chapters (ie, cauterisation treatments, surgical procedures and fractures and dislocations). Although the main source of the book was Al-Tasrif (Textbook of Surgery) by Albucasis (Abu al-Qasim al-Zahrawi; 936-1013 AD), Sabuncuo?lu added much new information, his clinical experiences and suggestions. The original illustrations and human figures made Cerrahiyetü'l-Haniyye the first illustrated medical textbook in Turkish and Islamic medicine literature. Cerrahiyetü'l-Haniyye was also a valuable source for acupuncturists. Some new sections and additions revealed that Sabuncuo?lu had knowledge of Chinese medicine. In four sections of Cerrahiyetü'l-Haniyye (ie, toothache, haemorrhoids, eczema and dermatophytosis) Sabuncuo?lu described acupuncture techniques and point locations. It is likely that the Chinese medicine content of Cerrahiyetü'l-Haniyye was derived from Central Asian roots of Anatolian Turkish people. PMID:25380833

Human platelet antigen genotypes in Turkish and Caucasian blood donors in Germany.  

PubMed

Exposition to allogenic human platelet antigens (HPAs) can lead to antibody formation causing neonatal alloimmune thrombocytopenia (NAIT), post-transfusion purpura or platelet (PLT) transfusion refractoriness. The frequencies of HPA differ between ethnical groups which could be associated with different potential alloimmunization risk. The Turkish population is the largest ethnic minority group living in Germany. However, no data are available about the HPA frequency among Turkish population. We compared the frequency of HPA between Caucasian and Turkish blood donors. DNA from blood samples of 119 Caucasian and 117 Turkish blood donors was isolated. The genotype of HPA-1, -2, -3 -4, -5 and -15 was determined using a commercialized polymerase chain reaction kit with sequence-specific primers. In Turkish blood donors, the gene frequencies of HPA-1a/1b, -2a/2b, -3a/3b, -4a/4b, -5a/5b and -15a/15b were 0.863/0.137, 0.868/0.133, 0.607/0.393, 0.996/0.004, 0.893/0.107 and 0.474/0.256, respectively. In Caucasians, we observed 0.798/0.202, 0.908/0.092, 0.567/0.432, 1.000/0.000, 0.916/0.084 and 0.517/0.483 for HPA-1a/1b, -2a/2b, -3a/3b, -4a/4b, -5a/5b and -15a/15b, respectively. No statistically significant difference between genotypes in these populations could be observed. Due to the similar distribution of HPA genotypes in both ethnical groups, no increased risk of NAIT for children of mixed couples or of post-transfusion purpura or PLT transfusion refractoriness secondary to antibodies to HPAs for recipients of PLT concentrates from blood donors of the other ethnicity is given.

Self-esteem and the evaluation of ethnic identity among Turkish and Dutch adolescents in The Netherlands.  

PubMed

A nationwide sample of Turkish and Dutch adolescents was used to answer two questions. Do Turkish youths in the Netherlands demonstrate negative effects of minority status on global self-esteem or specific components of self-esteem? What is the meaning of ethnic identity for the self-concept of these youngsters? The results showed that Turkish adolescents had a lower score for global self-esteem and a higher score for three components--academic ability, sports achievements, and evaluation of one's ethnic identity. However, in terms of the percentage of variance explained, the differences were very small. The results also showed that ethnic identity was a more salient and more important aspect of self-concept for the Turkish subjects than for the Dutch. It was not, however, a dominant component of their self-concept: The other components had a greater impact on global self-esteem. Body image was the most important component in this respect.

Iranian Azeri’s Y-Chromosomal Diversity in the Context of Turkish-Speaking Populations of the Middle East  

PubMed Central

Background: The main goal of this study was to conduct a comparative population genetic study of Turkish speaking Iranian Azeries as being the biggest ethno-linguistic community, based on the polymorph markers on Y chromosome. Methods: One hundred Turkish-speaking Azeri males from north-west Iran (Tabriz, 2008–2009) were selected based on living 3 generations paternally in the same region and not having any relationship with each other. Samples were collected by mouth swabs, DNA extracted and multiplex PCR done, then 12 Single Nucleotide Polymorphisms (SNPs) and 6 Microsatellites (MS) were sequenced. Obtained data were statistically analyzed by Arlequin software. Results: SNPs and Microsatellites typing were compared with neighboring Turkish-speaking populations (from Turkey and Azerbaijan) and Turkmens representing a possible source group who imposed the Turkish language during 11–15th centuries AD. Azeris demonstrated high level of gene diversity compatible with patterns registered in the neighboring Turkish-speaking populations, whereas the Turkmens displayed significantly lower level of genetic variation. This rate of genetic affiliation depends primarily on the geographic proximity. Conclusion: The imposition of Turkish language to this region was realized predominantly by the process of elite dominance, i.e. by the limited number of invaders who left only weak patrilineal genetic trace in modern populations of the region.

Turkish lupusPRO: cross-cultural validation study for lupus.  

PubMed

LupusPRO is a disease-targeted patient-reported outcome measure that was developed and validated from and among US patients with systemic lupus erythematosus (SLE). We herein report the results of the cross-cultural adaptation and validation study of the Turkish translated version of the LupusPRO. Turkish LupusPRO and the Medical Outcomes Study Short Form (SF-36) (Turkish) were administered to the Turkish lupus patients. Disease activity was ascertained using the physician global assessment (PGA), Safety of Estrogens in Lupus Erythematosus National Assessment-Systemic Lupus Erythematosus Disease Activity Index (SELENA-SLEDAI), and flare (defined by LFA-Lupus Foundation of America). Disease damage was assessed with Systemic Lupus International Collaborating Clinics/American College of Rheumatology damage index (SDI). Also, second Turkish LupusPRO tests were given to the patients to be completed within 2-3 days and sent back to us. Internal consistency reliability, test-retest reliability, and convergent and criterion validity (against disease activity or health status) were tested. All reported p values are two-tailed. The conceptual framework of the LupusPRO was evaluated using confirmatory factor analysis appropriate for categorical data. One hundred two SLE subjects (94 % women) were enrolled. The median (IQR) age and mean disease duration (±SD) were 38.5 (18) years and 60.3 (±56.3) months, respectively. The mean?±?SD, SLEDAI, and SDI scores were 3.1?±?3.7 and 0.52?±?0.75, respectively. There were 25 patients who had flares at the time of study. Forty-two patients with no change in their health status completed and sent back the second LupusPRO test and were included in the test-retest analysis. Test-retest reliability of LupusPRO domains ranged from 0.87 to 0.97, while internal consistency reliability of the domains ranged from 0.63 to 0.94. Convergent validity with corresponding domains of SF-36 was present. Health-related quality-of-life domains performed well against disease activity measures (PGA, total SLEDAI, LFA flare, and SF-6D-overall health status), establishing its criterion validity. Item-to-factor loadings representing the hypothesized item-to-scale relationships were satisfactory. The model fit for the hypothesized item-to-scale relationships was also satisfactory.

A national survey of Turkish emergency physicians perspectives regarding family witnessed cardiopulmonary resuscitation.  

PubMed

We investigated Turkish emergency physicians' views regarding family witnessed resuscitation (FWR) and to determine the current practice in Turkish academic emergency departments with regard to family members during resuscitation. A national cross-sectional, anonymous survey of emergency physicians working in academic emergency departments was conducted. Nineteen of the 23 university-based emergency medicine programs participated in the study. Two hundred and thirty-nine physicians completed the survey. Of the respondents, 83% did not endorse FWR. The most common reasons for not endorsing FWR was reported as higher stress levels of the resuscitation team and fear of causing physiological trauma to family members. Previous experience, previous knowledge in FWR, higher level of training and the acceptance of FWR in the institution where the participant works were associated with higher rates of FWR endorsement for this practice among emergency physicians.

Financial literacy among Turkish college students: the role of formal education, learning approaches, and parental teaching.  

PubMed

This study assessed financial literacy and its correlates among Turkish college students, with special emphasis on the role of formal education, learning approaches, and parental influences. Financial literacy was measured by the College Student Financial Literacy Survey, which assesses knowledge in four areas: general financial management, saving and borrowing, insurance, and investing. 853 Turkish university students were administered the survey (416 men, 437 women; M age = 20.3 yr., SD = 0.6). The mean percentage of correct responses was 45% (SD = 12.8%). Regression results showed that formal finance education in college, a deep approach to learning, and direct financial teaching by parents were significantly associated with higher financial literacy scores.

Exploring academic procrastination among Turkish students: possible gender differences in prevalence and reasons.  

PubMed

The authors examined the prevalence of and reasons, or excuses, for academic procrastination as a function of gender and academic grade level. In Study 1, a factor analysis of responses by 203 Turkish undergraduate students to an academic procrastination measure provided evidence of reliability and validity for the revised scale. In Study 2,784 students (363 women, 421 men; M age = 20.6 years, SD age = 1.74 years) completed the validated Turkish Procrastination Assessment Scale-Students. The results were that 52% of students self-reported frequent academic procrastination, with male students reporting more frequent procrastination on academic tasks than female students. Significantly more female students than male students reported greater academic procrastination because of fear of failure and laziness; male students reported more academic procrastination as a result of risk taking and rebellion against control than did female students.

The purpose of the current study was to examine the validity and reliability of (Journal of Marital and Family Therapy 2003, 29, 209) Differentiation of Self Inventory-Revised (DSI-R; Skowron & Schmit, 2003) in Turkish adults. The DSI-R was translated, independently back-translated, and revised. Two independent samples of adults over the age of 25 were used. The original 46-item DSI-R was not supported by the data derived from Sample 1 (n = 221). However, a revised 20-item, four-factor model fit the data well. This 20-item model was subsequently cross-validated with a second sample of Turkish adults (n = 187). Scale scores showed adequate internal consistency, 5-week test-retest reliability, and satisfactory convergent and criterion-related validity. It was concluded that Turkish DSI-R (DSI-T) is a valid and reliable measure to assess an individual's differentiation level. In light of the findings, implications for the use of the DSI-T and ideas for future research are discussed. PMID:24749993

Objective: Time-related changes and comparisons for mid-upper arm circumference (MUAC), triceps skinfold thickness (TSF), arm fat area (AFA) are lacking for Turkish children and adolescents. To determine the arm anthropometry indices (MUAC, TSF, AFA) in children and adolescents and to also assess the changes in these indices over a 3-year time period. Methods: The data of the Anthropometry of Turkish Children Aged 0-6 Years (ATCA-06) study and the Second Study of Determination of the Anthropometric Measurements of Turkish Children and Adolescents (DAMTCA-II) were used to calculate the arm anthropometry percentiles in a total group of 6982 children and adolescents aged 28 days to 17 years. The 3rd-97th percentiles were computed by the LMS method. Results: In girls, 50th percentile MUAC values linearly increased with age. In boys, 50th percentile TSF values linearly increased until 10 years of age and decreased after age 11 years, while in girls, TSF values increased linearly with age. 50th percentile values for AFA showed a linear increase in both genders with age. Significant differences were found between the 5th, 50th and 95th percentile values for MUAC and AFA obtained in the two studies (DAMTCA-II and DAMTCA-I) in both boys and girls. Conclusions: The prominent finding was the significant and alarming increase in arm anthropometry indices in both genders within as short period of time as three years. PMID:25541892

Molecular identification, genotyping, and drug susceptibility of the basidiomycetous yeast pathogen Trichosporon isolated from Turkish patients.  

PubMed

Deep-seated infections due to Trichosporon species are emerging mycoses that have a very poor prognosis in patients with persistent neutropenia. This study elucidated the mycological characteristics of Trichosporon strains obtained from deep-seated infections in Turkish patients and identified by DNA sequence analysis of intergenic spacer (IGS) region 1 of the rDNA locus. In addition, we genotyped the major causative agent, T. asahii, and evaluated the in vitro drug susceptibility of the isolates. While 87 (81.3%) of the 107 isolates were T. asahii, the remaining 20 were T. faecale (14.0%), T. asteroids (0.9%), T. coremiiforme (0.9%), T. japonicum, (0.9%), T. lactis (0.9%), and a new species (0.9%). In addition to the eight known T. asahii genotypes, one novel genotype was identified. The distribution of the T. asahii genotypes in this study were genotype 1 (79.3%), followed by 5 (8.0%), 3 (6.9%), 6 (3.4%), 4 (1.1%), and 9 (1.1%). Turkish isolates showed low susceptibility to amphotericin B, 5-flucytosine, and fluconazole. Although relatively low minimum inhibitory concentrations (MICs) were found with all drugs, voriconazole appeared to be the most active. The MICs of the non-Trichosporon asahiiTrichosporon species were similar to those of the T. asahii strains. Our findings suggest that Trichosporon species isolated from Turkish patients are more diverse than those reported from other countries. PMID:19462333

A study on exhaust gas emissions from ships in Turkish Straits  

NASA Astrophysics Data System (ADS)

The Turkish Straits, i.e. Istanbul (Bosphorus) and Canakkale (Dardanellen), which connect Black Sea and Aegean Sea, have a continuously increasing maritime traffic. Especially, the maritime traffic on Bosphorus (Istanbul Strait) that connects the continents of Europe and Asia is too complex due to geographical conditions. The maritime traffic in the Turkish Straits includes the ships, which are in use in domestic transport, the transit passing ships with various aims and fishing, sport or strolling ships. In this paper, fuel consumption and exhaust gas emissions NO x, CO, CO 2, VOC, PM exhausted from ships such as transit vessels, which are passing both Bosphorus and Dardanellen, and passenger ships used in domestic transport on the Bosphorus are calculated. In order to do this the general characteristics, the main engine systems, the fuel types, cruising times and speeds of all vessels are taken into consideration. The calculated NO x emissions on the Bosphorus are 2720 t from domestic passenger ships and 4357 t from transit ships. In this case it is clear that the transit ships cause more than half of the total amount of emissions from ships on the Bosphorus. The amount of nitrogen oxide emissions from domestic passenger ships used for public transport in Istanbul Strait is equal to approx. 4% of nitrogen oxide emissions from motor vehicles in Istanbul. Finally, the future emissions from ships in Turkish Straits are discussed.

Analysis of the effects of the global financial crisis on the Turkish economy, using hierarchical methods  

NASA Astrophysics Data System (ADS)

We have analyzed the topology of 50 important Turkish companies for the period 2006-2010 using the concept of hierarchical methods (the minimal spanning tree (MST) and hierarchical tree (HT)). We investigated the statistical reliability of links between companies in the MST by using the bootstrap technique. We also used the average linkage cluster analysis (ALCA) technique to observe the cluster structures much better. The MST and HT are known as useful tools to perceive and detect global structure, taxonomy, and hierarchy in financial data. We obtained four clusters of companies according to their proximity. We also observed that the Banks and Holdings cluster always forms in the centre of the MSTs for the periods 2006-2007, 2008, and 2009-2010. The clusters match nicely with their common production activities or their strong interrelationship. The effects of the Automobile sector increased after the global financial crisis due to the temporary incentives provided by the Turkish government. We find that Turkish companies were not very affected by the global financial crisis.

[Two Turkish manuscripts on gems (jauhar) and the treatment by means of gems].  

PubMed

Literary works of the genre called cevâhir-nâme or cevher-nâme are written in order to give information on how gems (cevher-jauhar) are formed, where they are found, their estimated values, how to distinguish them from the imitations, what their particular colours are and on their uses and harmful effects. These literary works are sometimes titled in accordance with the genre they belong to and sometimes they are given different titles. The literary works dealing with the subject of cevher are mostly written in prose and only a few of them are in verse. The Turkish versions of cevâhir-nâme texts started to be written in the 15th century. These texts, covering the earlier knowledge of medicine, give information on gems and perfumes; how they effect human health; and the way they should be used in medical treatment. Therefore, these texts should be discussed in relation with their place in the history of Turkish science. Two cevâhir-nâmes, which were translated into Turkish by Mustafâ bin Seydî and Za'îfî in the 15th and 16th centuries are still available. The translations by Mustafâ bin Seydî and Za'îfî, did not only convey the classical and medieval knowledge on cevhers to the contemporary readers, but they also confirm the fact that this information was a part of the Ottoman social life.

Between Western Europe and the Middle East: changing patterns of Turkish labour migration.  

PubMed

The authors examine Turkish labor migration to Western Europe prior to 1973 and to the Middle East since that date. "The growth, organization and characteristics of these two phases in Turkish migration history are compared and contrasted. Particular emphasis is paid to the patterns of migrant worker origin and rates of emigration in the two periods. During the period 1961-73 the pattern of migration was dominated by the metropolitan and developed areas of Western Turkey. The re-direction of migration to Saudi Arabia, Libya and Iraq has been accompanied by a contraction and eastward shift in the main areas of migrant origins. Developments in the pattern of migrant worker origins are related to changes in the skill composition of the migrants and the mechanisms of the migration process. Opportunities for the employment of Turkish workers in the Arab world appear to have peaked and, although it has produced some short-term financial advantages, it has had little effect on Turkey's employment problems."

Development of a problematic mobile phone use scale for Turkish adolescents.  

PubMed

Abstract The aim of this study was to evaluate the psychometric properties of the Problematic Mobile Phone Use Scale (PMPUS) for Turkish Adolescents. The psychometric properties of PMPUS were tested in two separate sample groups that consisted of 950 Turkish high school students. The first sample group (n=309) was used to determine the factor structure of the scale. The second sample group (n=461) was used to test data conformity with the identified structure, discriminant validity and concurrent scale validity, internal consistency reliability calculations, and item statistics calculations. The results of exploratory factor analyses indicated that the scale had three factors: interference with negative effect, compulsion/persistence, and withdrawal/tolerance. The results showed that item and construct reliability values yielded satisfactory rates in general for the three-factor construct. On the other hand, the average variance extracted value remained below the scale value for three subscales. The scores for the scale significantly correlated with depression and loneliness. In addition, the discriminant validity value was above the scale in all sub-dimensions except one. Based on these data, the reliability of the PMPUS scale appears to be satisfactory and provides good internal consistency. Therefore, with limited exception, the PMPUS was found to be reliable and valid in the context of Turkish adolescents. PMID:22304426

Emotion displays in media: a comparison between American, Romanian, and Turkish children's storybooks  

PubMed Central

Children's books may provide an important resource of culturally appropriate emotions. This study investigates emotion displays in children's storybooks for preschoolers from Romania, Turkey, and the US in order to analyze cultural norms of emotions. We derived some hypotheses by referring to cross-cultural studies about emotion and emotion socialization. For such media analyses, the frequency rate of certain emotion displays can be seen as an indicator for the salience of the specific emotion. We expected that all children's storybooks would highlight dominantly positive emotions and that US children's storybooks would display negative powerful emotions (e.g., anger) more often and negative powerless emotions (e.g., sadness) less often than Turkish and Romanian storybooks. We also predicted that the positive and negative powerful emotion expressions would be more intense in the US storybooks compared to the other storybooks. Finally, we expected that social context (ingroup/outgroup) may affect the intensity emotion displays more in Turkish and Romanian storybooks compared to US storybooks. Illustrations in 30 popular children's storybooks (10 for each cultural group) were coded. Results mostly confirmed the hypotheses but also pointed to differences between Romanian and Turkish storybooks. Overall, the study supports the conclusion that culture-specific emotion norms are reflected in media to which young children are exposed. PMID:24987384

The oceanic response of the Turkish Straits System to an extreme drop in atmospheric pressure  

NASA Astrophysics Data System (ADS)

across all four entry/exit sections of the Dardanelles Strait and the Bosphorus Strait simultaneously measured the response of the Turkish Straits System to the passage of a severe cyclonic storm that included an atmospheric pressure drop of more than 30 mbar in less than 48 h. The bottom pressure response at the Aegean Sea side of the Dardanelles Strait was consistent with an inverted barometer response, but the response at the other sections did not follow an inverted barometer, leading to a large bottom pressure gradient through the Turkish Straits System. Upper-layer flow toward the Aegean Sea was reversed by the storm and flow toward the Black Sea was greatly enhanced. Bottom pressure across the Sea of Marmara peaked 6 h after the passage of the storm's minimum pressure. The response on the Dardanelles side was a combination of sea elevation and pycnocline depth rise, and the response on the Bosphorus side was an even greater sea elevation rise and a drop in pycnocline depth. The peak in bottom pressure in the Sea of Marmara was followed by another reverse in the flow through the Dardanelles Strait as flow was then directed away from the Sea of Marmara in both straits. A simple conceptual model without wind is able to explain fluctuations in bottom pressure in the Sea of Marmara to a 0.89-0.96 level of correlation. This stresses the importance of atmospheric pressure dynamics in driving the mass flux of the Turkish Strait System for extreme storms.

Reducing unnecessary prescriptions of antibiotics for acute cough: Adaptation of a leaflet aimed at Turkish immigrants in Germany  

PubMed Central

Background The reduction in the number of unnecessary prescriptions of antibiotics has become one of the most important objectives for primary health care. German GPs report that they are under "pressure to prescribe" antibiotics particularly in consultations with Turkish immigrants. And so a qualitative approach was used to learn more about the socio-medical context of Turkish patients in regard to acute coughs. A German leaflet designed to improve the doctor-patient communication has been positively tested and then adapted for Turkish patients. Methods The original leaflet was first translated into Turkish. Then 57 patients belonging to 8 different GPs were interviewed about the leaflet using a semi-standardised script. The material was audio recorded, fully transcribed, and analysed by three independent researchers. As a first step a comprehensive content analysis was performed. Secondly, elements crucial to any Turkish version of the leaflet were identified. Results The interviews showed that the leaflets' messages were clearly understood by all patients irrespective of age, gender, and educational background. We identified no major problems in the perception of the translated leaflet but identified several minor points which could be improved. We found that patients were starting to reconsider their attitudes after reading the leaflet. Conclusion The leaflet successfully imparted relevant and new information to the target patients. A qualitative approach is a feasible way to prove general acceptance and provides additional information for its adaptation to medico-cultural factors. PMID:18847464

Data on the PCR Turkish population based loci: LDLR, GYPA, HBGG, D7S8, and Gc.  

PubMed

Allele and genotype frequencies for the five PCR-based loci were analyzed in 157 unrelated Turkish individuals. The five PCR-based loci included LDLR, GYPA, HBGG, D7S8, and Gc. The results of the chi-square and exact tests showed that the genotype distribution at the LDLR, GYPA, D7S8, and Gc loci did not significantly differ from the Hardy-Weinberg Expectation (HWE). However, the genotype distribution at the HBGG locus did not conform to HWE. Moreover, the genotype frequencies calculated in this study were compared with the published genotype frequencies of US African American and US Caucasian populations. The Turkish population was significantly different at the HBGG locus from the US Caucasian population. However, there were highly significant differences at the LDLR, HBGG, and Gc loci between the Turkish and African American populations. PMID:10582364

Circadian variation of acute st segment elevation myocardial infarction by anatomic location in a Turkish cohort  

PubMed Central

Summary Background To evaluate the relationship between site of infarction (anterior vs. inferior) and circadian variation in patients with ST segment elevation myocardial infarction (STEMI) in a Turkish cohort. Material/Methods This restrospective study enrolled 465 patients (407 male, mean age 65±7 years) with STEMI. Patients were then categorised into 4 6-hour increments according to the time of day during which the symptoms began (12:00 AM–06:00 AM, 06:00 AM–12:00 PM; 12:00 PM–06:00 PM and 06:00 PM–12:00 AM hours). Characteristics of patients by site of infarction (anterior vs. inferior) were compared. Results The frequency of onset of acute anterior MI as determined by onset of pain demonstrated significant circadian variation among the 4 time periods, demonstrating bimodal peaks (afternoon and morning) and a trough between 06:00 PM to 06:00 AM. The incidence of occurrence of MI between 06:00 AM to 06:00 PM was 4.50 times that of the average frequency of the remaining 12 hours of the day. The frequency of onset of acute inferior MI as determined by onset of pain exhibited significant circadian variation among the 4 time periods, demonstrating bimodal peaks (midnight to 06:00 AM and 06:00 AM to noon) and a trough between noon to midnight. The incidence of occurrence of MI between midnight to noon was 4.25 times that of the average frequency of the remaining 12 hours of the day. Conclusions Different circadian periodicity in the time of onset of STEMI was found regarding infarction site in a Turkish cohort. This may be related to genetic and/or demographic characteristics of the Turkish population. PMID:21455107

[How do Turkish immigrants evaluate cultural sensitivity in a German tertiary hospital?].  

PubMed

Background | Culturally adequate medical care is a goal in Germany, but quantitative data concerning inpatients is lacking. Methods | Inpatients of a German tertiary hospital: Turkish migrants (T) and Germans (G) were interviewed in their respective native language. Results | 121?T and 121 G were interviewed. 97.5?% of T were Muslims, 82.6?% of G were Christians. 88.5?% of T judged religion as "important" or "very important" (G: 35.8?%). 50.8?% of T saw their opportunity to pray in the hospital as "bad" or "very bad" (G: 0.9?%). Keeping to Islamic dietary rules in the hospital was "difficult" or "very difficult" for 90?% of T. For 79.0?% of female T care by a same-sex staff was "important" or "very important" (female G: 36.3?%, male T: 40.0?%, male G: 7.7?%). The presence of a same-sex person during examinations or treatments was "much" or "very much" appreciated by 69.7?% of female T, if same-sex care was impossible (female G: 25.4?%, male T: 28.9?%, male G: 6.1?%). A retrospective analysis revealed that 5.8?% of all 8988 hospital admissions during the period of study recruitment were Turkish migrants. Conclusion | To meet the needs of Turkish migrants German hospitals should improve the opportunity for Muslims to pray. Additionally, the cooperation with local imams should be sought. Precise descriptions of food ingredients or an adapted menu could help T to deal with Muslim dietary commandments. A culturally sensitive hospital should take into account that female as well as male T prefer to be cared of by same-sex physicians and nurses. PMID:25612288

Validation of the Turkish version of the quality of recovery-40 questionnaire  

PubMed Central

Background The Quality of Recovery-40 questionnaire (QoR-40) is a self-rated questionnaire used to assess the postoperative recovery quality and health status of patients in the early stages following surgery; however, there is no Turkish version of the QoR-40. The aim of this study was to assess the reliability, validity, and responsiveness of the Turkish version of the QoR-40 (QoR-40 T). Methods After the approval of the ethics committee, a total of 137 patients completed the questionnaire during the preoperative period, on the third day, and one month after surgery. The quality of life was evaluated by using a health-related quality of life questionnaire (Short-Form Health Survey-36; SF-36) on the third day and one month after surgery. Reliability, feasibility, and validity were assessed to validate the QoR-40 T. Results The Cronbach’s alpha of the global QoR-40 T on the third day after surgery was 0.936. A positive moderate correlation was obtained between the physical comfort, emotional state, physical independence, and pain dimensions of the QoR-40 T and the physical component summary, mental health, physical functioning, and bodily pain subscales of the SF-36 on the third day after surgery, respectively (physical comfort - physical component summary, ??=?0.292, p?=?0.001; emotional state - mental health, ??=?0.252, p?=?0.003; physical independence - physical functioning, ??=?0.340, p?Turkish population.

Facebook addiction among Turkish college students: the role of psychological health, demographic, and usage characteristics.  

PubMed

This study explored Facebook addiction among Turkish college students and its behavioral, demographic, and psychological health predictors. The Facebook Addiction Scale (FAS) was developed and its construct validity was assessed through factor analyses. A total of 447 students reported their personal information and Facebook usage and completed the FAS and General Health Questionnaire (GHQ-28). The results revealed that weekly time commitment, social motives, severe depression, and anxiety and insomnia positively predicted Facebook addiction. Neither demographic variables nor the interactions of gender by usage characteristics were found to be significant predictors. PMID:23286695

Applicability of the Demirjian method for dental assessment of southern Turkish children.  

PubMed

Age-related legal problems are especially common in underdeveloped parts of Turkey. In terms of civil and criminal law, the ages from 13 years to 18 years are critical in our country. Estimation of age is a very significant in aspect of accordance with laws. The aims of this study were to evaluate the applicability and accuracy of the Demirjian technique for assessing southern Turkish children; to analyze the sexual dimorphism of dental age in the studied groups; and to define the relationship between the dental age and the degree of mineralization in mandibular permanent tooth in southern Turkish children. This study was performed using panoramic radiographs from 932 healthy southern Turkish children, 444 girls and 488 boys aged between 4 and 18 years. Statistical evaluations were performed using SPSS (Statistical Package for Social Sciences) for Windows 13.0 software. The mean difference between dental and chronological age was calculated for each age and sex group. The paired t-test was used to compare all data. The chi-square test was used for between-group comparisons of categorical variables. Continuous variables were tested for normality using the Kolmogorov-Smirnov test. Relationships between continuous variables were examined using Pearson's correlation coefficient. The same observer re-examined 700 teeth three months after the first examination. The results were evaluated with the intraclass correlation test and both measurements were statistically significantly similar with each other(R = 0.982, p = 0.0001). .Dental age (DA) and chronological age (CA) were consistent for boys in the 16-16.9 age group and for girls in the 9-9.9 and 15-15.9 age groups. From this study, we can conclude that dental age varies across ethnic populations. Additionally, dental maturation varies across different regions of the same country. Because Demirjian's standards are not suitable for all age groups of southern Turkish children, a new table is necessary for evaluating this population. Future studies using multi-ethnic population data are needed to establish the international applicability of Demirjian's method. PMID:24931852

College Science Teaching Changing to Mirror Real Science in Turkish Higher Education  

NSDL National Science Digital Library

College science is often poorly taught and it is rare that any consideration is given to the nine visions for reform of science teaching featured in the National Science Education Standards (NSES) (NRC 1996, p. 52). It is even more rare to see interdisciplinary science courses taught in colleges. At many universities, this is changing where there are Science-Technology-Society (STS) enthusiasts. For example, Clemson University (Cheek 2006) is struggling with developing such courses as part of their general education requirements for all undergraduates and similar changes are occurring in Turkish higher education.

Effect of some Turkish vegetable oil-diesel fuel blends on exhaust emissions  

SciTech Connect

For different types of vegetable oils of Turkish origin (sunflower, corn, soybean, and olive oil) were blended with grade No. 2-D diesel fuel at a ratio of 20/80 (v/v). The effect of the compression ratio on exhaust emissions is investigated in an American Society for Testing and Materials (ASTM)-cooperative fuel research (CFR) engine working with the mentioned fuel blends and a baseline diesel fuel. A decrease in soot, CO, CO{sub 2}, and HC emissions and an increase in NO{sub x} emissions have been observed for fuel blends compared to diesel fuel.

SciTech Connect

Four different types of vegetable oils of Turkish origin (sunflower, corn, soybean, and olive oil) were blended with grade 2-D diesel fuel at a ratio of 20/80 (v/v). Blends were investigated in a diesel engine with a precombustion chamber at speeds between 1,200 and 2,100 rpm. Vegetable oils, diesel fuel, and fuel blends were characterized according to standard test methods. It was found that for short-term use, the fuel blends have engine characteristics similar to the baseline diesel fuel. Fuel blends also display less smoke emissions than diesel fuel.

Comparing psychological responses of internally displaced and non-displaced Turkish Cypriots.  

PubMed

During the 1963-1964 ethnic conflict and 1974 war in Cyprus, many Turkish Cypriots were displaced by Greek Cypriot forces. The psychological condition of Turkish Cypriots after these conflicts has not been studied to the present day. At the time of the Annan Plan Referendum on April 24th 2004, when people on both sides were to decide whether to reunite or not, and when old traumatic events where being discussed in vivid detail, the psychological responses of the internally displaced and non-displaced Turkish Cypriots were investigated. The sample of the study derived from a sample of a larger household survey study conducted on 408 adult people taken randomly from three different districts. People who settled down in Cyprus after 1974 or who had never experienced a war in Cyprus were not included in the study. 129 Turkish Cypriots who experienced either 1963-64 conflict or the 1974 war were included in the present study. 86 of these had been displaced. The first part of the questionnaire that was administered to the subjects included demographic characteristics, war-related traumatic experiences, the level of seriousness, and traumatic incidents resulting from other circumstances. In the second part of the questionnaire, the Traumatic Stress Symptom Checklist (TSSC) and Brief Symptom Inventory (BSI) were used to investigate the symptoms of the post-traumatic process. The outcomes indicates that the internally displaced persons (IDPs) where subjected to traumatic incidents at a higher degree due to killing, displacement, captivity, or killing of family members and relatives. The rate of posttraumatic stress disorder (PTSD) of IDPs is 20%, and is significantly higher than for non-displaced persons. The comparison of BSI subscales show that IDPs had a higher level of depression scores than the non-displaced persons. The somatization subscale scores are higher in non-displaced persons. The study reveals a higher frequency of war-related traumatic events in IDPs than in non-displaced people, greater suffering from posttraumatic stress and more negative beliefs about future reunion.

High frequency of GJA12/GJC2 mutations in Turkish patients with Pelizaeus-Merzbacher disease.  

PubMed

Pelizaeus-Merzbacher disease is an early onset dysmyelinating leukodystrophy. About 80% of PMD cases have been associated with duplications and mutations of the proteolipid protein 1 (PLP1) gene. Pelizaeus-Merzbacher-like disease is a genetically heterogeneous autosomal recessive disease and rarely caused by mutations in gap junction protein ?12 (GJA12/GJC2) gene. The molecular basis of the disease was investigated in a cohort of 19 Turkish families. This study identified novel chromosomal rearrangements proximal and distal to, and exclusive of the PLP1 gene, showed equal frequencies of PLP1 and GJA12/GJC2 mutations at least in our cohort, and suggested further genetic heterogeneity.

Benefit and Adherence of the Disease Management Program “Diabetes 2”: A Comparison of Turkish Immigrants and German Natives with Diabetes  

PubMed Central

There is an ongoing debate about equity and equality in health care, and whether immigrants benefit equally from services as the non-immigrant population. The study focuses on benefits from and adherence to the diabetes mellitus type 2 (DM 2) disease management program (DMP) among Turkish immigrants in Germany. So far, it has not been researched whether this group benefits from enrollment in the DMP as well as diabetics from the non-immigrant population. Data on the non-immigrant sample (N = 702) stem from a survey among members of a German health insurance, the Turkish immigrant sample (N = 102) was recruited in the area of Hamburg. Identical questions in both surveys enable comparing major components. Regarding process quality, Turkish diabetics do not differ from the non-immigrant sample; moreover, they have significantly more often received documentation and diabetes training. In terms of outcome quality however, results display a greater benefit on behalf of the non-immigrant sample (e.g., blood parameters and body mass index), and they also met more of the DMP criteria. This underlines the need of diabetics with Turkish background for further education and information in order to become the empowered patient as is intended by the DMP as well as to prevent comorbidities.

Social representation of events in world history: crosscultural consensus or Western discourse? How Turkish students view events in world history.  

PubMed

The perceptions of historical events are considered to be an important cultural, political, and social psychological variable. Earlier studies have shown a crosscultural consensus on historical events that are considered to be important. It has been indicated that a strong Western-Christian European template dominates the view of which events are considered to be important events in history, by many samples across the world. It was the aim of this study to test this finding with a Turkish sample, which would represent some unique characteristics in that it is Muslim, comes from an Empire background, and has undergone a recent nation-building process. College students (n?=?372) responded to a questionnaire that was utilized in seven other countries. It was shown that Turkish students were not Eurocentric as expected by the literature: They were highly sociocentric; they gave importance to events related to Turkish history. They were similar to their European counterparts in that war and violence were given primary importance when selecting events as important in history. However, they did not behave as predicted by earlier literature: They did not see Western European events as having a primary importance in history but gave at least equal importance to events that originated from Ottoman Empire roots. The results were discussed in terms of the unique cultural and historical variables that contribute to the identity and social psychological attributions of Turkish students. Further research should focus on not only which events are considered as important historical events but also the reasons behind these. PMID:22827603

Depressive symptoms and smoking among young Turkish and Moroccan ethnic minority groups in the Netherlands: a cross-sectional study  

PubMed Central

Background Although evidence indicates a strong association between depressive symptoms and smoking among host and migrant adults, less is known about this relationship among young ethnic minority groups in Europe. This paper aims to assess the relationship between depressive symptoms and smoking among young Turkish and Moroccan migrants in the Netherlands. Methods Multiple logistic regression analyses was used to analyze cross-sectional data from a sample of 364 Turkish and Moroccan migrants aged 15 to 24 years. The Center for Epidemiologic Studies Depression Scale (CES-D) was used to measure the presence of clinically significant depressive symptoms. Smoking behavior was measured by a number of questions. Results Of the respondents, 22% were smokers and 33% had depressive symptoms. The prevalence of depressive symptoms was significantly higher in smokers (42.9%) than in nonsmokers (29.5%). Respondents with depressive symptoms had increased odds of smoking even after adjusting for socioeconomic and cultural factors (OR = 2.68, 95% CI = 1.45-4.97). Conclusions Depressive symptoms were significantly associated with smoking behavior in young Turkish and Moroccan migrants. In addition to other acknowledged factors, depressive symptoms should also be considered in relation to the smoking behavior of this group. Intervention programs for smoking behavior should take depressive symptoms into account for young Turkish and Moroccan migrants. PMID:21414199

Increased gastric cancer risk with PTEN IVS4 polymorphism in a Turkish population.  

PubMed

We aimed to investigate the association of the phosphatase and tensin homolog (PTEN) IVS4 polymorphism with a gastric cancer (GC) risk in the Turkish population. A hospital-based case-control study was conducted in 93 patients with GC, and 113 healthy controls. The PTEN IVS4 (rs no: 3830675) polymorphism was determined by using polymerase chain reaction-restriction fragment length polymorphism analysis. The PTEN IVS4 (-/-) genotype exhibited a significantly elevated risk for GC compared to controls (p<0.005; odds ratio: 1.6, 95% confidence interval: 1.19-2.14). Analyses on clinicopathological parameters showed that PTEN IVS4 genotypes were not associated with any of the variables of patients with GC (p>0.05). In conclusion, the PTEN IVS4 polymorphism might contribute to the development of GC in a Turkish population. Further studies, including comparison of the PTEN IVS4 polymorphism with plasma and tissue expressions of PTEN in larger study size groups will provide a further assessment of the PTEN IVS4 polymorphism in GC patients.

Patients' knowledge and awareness of dental implants in a Turkish subpopulation  

PubMed Central

PURPOSE The purpose of this study was to evaluate the patients' knowledge on dental implants in a Turkish subpopulation. MATERIALS AND METHODS Five hundred twenty seven Turkish adults referred to Yeditepe University Faculty of Dentistry, Istanbul, Turkey, were presented with a questionnaire including 20 questions regarding the level of information and awareness about the dental implants. The data were collected and statistical analyses were performed with Chi square test to compare the descriptive data. RESULTS Among 527 subjects, 54% were female and 46% were male with a mean age of 42.2 years. The rate of patients' implant awareness was 27.7%. When the patients were questioned about the treatment options for rehabilitation of tooth missing, 60.9% of patients were informed about fixed partial denture, followed by conventional complete denture (32.5%) and removable partial denture (24.9%). Six percent reported that they were very well informed about the dental implants whereas 48.2% were poorly informed. The information sources of the implants were from the dentist (44.5%), printed media (31.6%) and friends and acquaintances (17.3%), respectively. Sixteen percent of the population believed that their implants would last forever. CONCLUSION The dentists should give more detailed information to the patients about dental implants and tooth-supported fixed partial dentures in the future. PMID:24843399

The construct validity and reliability of the Turkish version of Spreitzer's psychological empowerment scale  

PubMed Central

Background Today, many organizations have adopted some kind of empowerment initiative for at least part of their workforce. Over the last two decades, two complementary perspectives on empowerment at work have emerged: structural and psychological empowerment. Psychological empowerment is a motivational construct manifested in four cognitions: meaning, competence, self-determination and impact. The aim of this article is to examine the construct validity and reliability of the Turkish translation of Spreitzer's psychological empowerment scale in a culturally diverse environment. Methods The scale contains four dimensions over 12 statements. Data were gathered from 260 nurses and 161 physicians. The dimensionality of the scale was evaluated by exploratory factor analyses. To investigate the multidimensional nature of the empowerment construct and the validity of the scale, first- and second-order confirmatory factor analysis was conducted. Furthermore, Cronbach alpha coefficients were assessed to investigate reliability. Results Exploratory factor analyses revealed that four factors in both solutions. The first- and second-order factor analysis indicated an acceptable fit between the data and the theoretical model for nurses and physicians. Cronbach alpha coefficients varied between 0.81-0.94 for both groups, which may be considered satisfactory. Conclusions The analyses indicated that the psychometric properties of the Turkish version of the scale can be considered satisfactory. PMID:20214770

Predoctoral prosthodontic curricula on removable partial dentures: survey of Turkish dental schools.  

PubMed

This study was conducted to evaluate the predoctoral removable partial denture (RPD) curricula in Turkish dental schools in regards to materials, techniques, and approaches. A questionnaire consisting of eighteen multiple-choice questions was sent by e-mail to the senior members of the prosthodontic departments of seventeen long-established dental schools in Turkey. The response rate was 100 percent. All schools (100 percent) used custom trays for making final impressions of partially dentate arches, taught border molding of the custom tray for the edentulous areas, used modeling plastic impression compound in border molding the final impression trays, and used base metal alloys for RPD frameworks. None of the schools had an in-house laboratory that fabricates RPD frameworks, and none of the students cast the frameworks of their own RPDs. The majority of schools used irreversible hydrocolloid as a final impression (70.6 percent) and dental surveyor (76.5 percent) in the designing of RPDs. The majority of schools did not flask their own RPDs (64.7 percent), did not treat patients using RPDs with attachments (76.5 percent), and did not perform the altered cast technique in bilateral and unilateral distal extension RPD cases (76.5 percent). Six teen schools (94.1 percent) had a minimum number of RPD arches that a student must complete in order to graduate. It was found that predoctoral RPD curricula in Turkish dental schools were both variable and similar. PMID:23314471

Recognition of Turkish Vowels by Probabilistic Neural Networks Using Yule-Walker AR Method  

NASA Astrophysics Data System (ADS)

In this work, recognition of vowels in Turkish Language by probabilistic neural networks is implemented using a spectral analysis method. Power spectral density of the phones obtained from speakers is estimated. Then weighted power spectrum is calculated after power spectral density of that phone is passed through a number of band pass filters. In this way, estimated power spectrums of the phones which are obtained from speakers approximate to a mel scale. Mel scale coefficients obtained, form the feature vector of the phone that is pronounced. These feature vectors constitute the database of the related speaker. Thus and so, every speaker has its own database. When it comes to recognize a phone pronounced by a speaker later, a probabilistic neural network model is created using the database belonging to that speaker. The feature vector of the phone which is to be recognized is computed as mentioned above. In this study, speaker-dependent recognition of Turkish vowels has been realized with an accuracy rate of over 95 percent.

Investigation of major international and Turkish companies via hierarchical methods and bootstrap approach  

NASA Astrophysics Data System (ADS)

We present a study, within the scope of econophysics, of the hierarchical structure of 98 among the largest international companies including 18 among the largest Turkish companies, namely Banks, Automobile, Software-hardware, Telecommunication Services, Energy and the Oil-Gas sectors, viewed as a network of interacting companies. We analyze the daily time series data of the Boerse-Frankfurt and Istanbul Stock Exchange. We examine the topological properties among the companies over the period 2006-2010 by using the concept of hierarchical structure methods (the minimal spanning tree (MST) and the hierarchical tree (HT)). The period is divided into three subperiods, namely 2006-2007, 2008 which was the year of global economic crisis, and 2009-2010, in order to test various time-windows and observe temporal evolution. We carry out bootstrap analyses to associate the value of statistical reliability to the links of the MSTs and HTs. We also use average linkage clustering analysis (ALCA) in order to better observe the cluster structure. From these studies, we find that the interactions among the Banks/Energy sectors and the other sectors were reduced after the global economic crisis; hence the effects of the Banks and Energy sectors on the correlations of all companies were decreased. Telecommunication Services were also greatly affected by the crisis. We also observed that the Automobile and Banks sectors, including Turkish companies as well as some companies from the USA, Japan and Germany were strongly correlated with each other in all periods.

Development of dental charts according to tooth development and eruption for Turkish children and young adults  

PubMed Central

Purpose 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. Materials and Methods 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. Results 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. Conclusion 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. PMID:24944959

Relationship of Internet addiction with impulsivity and severity of psychopathology among Turkish university students.  

PubMed

The previous studies have found a relationship between IA and both impulsivity and psychopathology when they were considered separately. The aim of this study was to investigate the relationship of Internet addiction (IA) with impulsivity and severity of psychopathology among Turkish university students. We also wanted to control the effect of impulsivity dimensions on the relationship between IA and psychopathology. A total of 319 university students from two universities in Ankara participated to the study. Students were assessed through the Internet Addiction Scale (IAS), the Symptom Checklist-Revised (SCL-90-R) and the Barratt Impulsiveness Scale-11 (BIS-11). Correlational analyses revealed that severity of IA was related to both SCL-90-R and BIS-11 scores. Among SCL-90-R subscales, severity of obsessive-compulsive symptoms (OCS) was the only predictor for IAS score. Hierarchical regression analysis indicated that interpersonal sensitivity, additional to attentional and motor impulsiveness, was the predictor of IAS score. Although severity of IA is associated with wide range of psychopathology, particularly OCS, interpersonal sensitivity seems to be the main dimension that predict severity of IAS additional to impulsiveness (attentional and motor). Impulsivity seems to be an important construct when considering IA and its treatment among Turkish university students. PMID:23998359

Partner Choice Patterns Among the Descendants of Turkish Immigrants in Europe.  

PubMed

We examine the partner choice patterns of second-generation Turks in 13 European cities in seven countries. We not only compare intermarriage versus endogamous marriage, but also explicitly include the choice of a second-generation partner of the same origin and of a partner of other migrant origin as important alternatives. In Europe, populations are made up increasingly of migrants and their descendants resulting in new alternative partner options not open before. Findings suggest that second-generation Turks who choose a second-generation partner seem to be located between the partner choice of a first-generation and native partner in terms of family values and contact to non-coethnic peers. The choice of a partner of other migrant origin hardly differs in these characteristics from the choice of a native partner. Context variables such as group size and type of integration policies seem to play a role for the likelihood of having a first-generation versus a second-generation partner of Turkish origin but not for the likelihood of exogamous partner choice. A second-generation partner is the most popular choice in Germany but represents a minor option in the other countries. Furthermore, a partner of other migrant origin is more common among men but is in some countries more popular than a native partner among Turkish second-generation men and women. PMID:23019383

Insecticidal activity of fatty acid-rich Turkish bryophyte extracts against Sitophilus granarius (Coleoptera: Curculionidae).  

PubMed

The composition of fatty acids and insecticidal effects was performed for the Turkish mosses Dicranum scoparium, Hypnum cupressiforme, Polytrichastrum formosum, Homalothecium lutescens and the Turkish liverwort Conocephalum conicum. All structures were determined by means of gas chromatography and gas chromatography-mass spectrometry techniques. The determination of fatty acids was done using a simple and mild method that utilized different solvent extractions ranging from nonpolar to polar solvents (hexane, dichloromethane, chloroform, ethyl acetate and methanol, respectively), and the samples were powdered with and without liquid nitrogen. The correlations between the saturated and unsaturated fatty acid contents depending on the solvent polarity and their crushing process by liquid nitrogen were observed. The insecticidal activity of the bryophytes was analyzed by using the methanol, hexane and esterified methanol extracts. The hexane extracts of Polytrichastrum formosum showed the highest insecticidal activity (70.33%) against Sitophilus granarius. Contact toxicity activities of lauric, myristic and palmitic acids besides single dose studies of the solvent extracts were carried out. The highest mortality rate (53.34%) was obtained from the myristic acid among the tested pure fatty acids. The activities of palmitic and lauric acids were 17.75% and 4.32%, respectively.

Frequency of angiotensin II type 1 receptor gene polymorphism in Turkish acute stroke patients.  

PubMed

This study was performed in acute stroke patients in the Turkish population to determine the frequency of the A1166C polymorphism in the AT1 gene and to examine the role of this polymorphism in acute stroke development. In this study, 257 genomic DNA samples were analysed (from 206 acute stroke patients and 51 healthy individuals). Genomic DNA was prepared from peripheral blood using the salt-extraction method. The presence of the A1166C polymorphism in the AT1 gene was determined using the polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) method. PCR products were separated by 2% agarose gel electrophoresis and visualized by a charge-coupled device (CCD) camera. In this study, the allele frequency at the A1166C position was 92% A and 8% C for control and 97% A and 3% C for patients. This difference in allele frequency between the control group and the patient group was not statistically significant. However, genotype and allele frequencies showed a significant difference (P < 0.001) in the control and the patient groups. The results of this study show no relationship between the A1166C polymorphism in the AT1 gene and acute stroke in the Turkish population. PMID:23480670

Relationship between plasminogen activator inhibitor type-1 (PAI-1) gene polymorphisms and osteoporosis in Turkish women  

PubMed Central

OBJECTIVE: The development of osteoporosis is associated with several risk factors, such as genetic structures that affect bone turnover and bone mass. The impact of genetic structures on osteoporosis is not known. Plasminogen activator inhibitor type-1 regulates the bone matrix and bone balance. This study assessed the correlation between plasminogen activator inhibitor type-1 gene 4G/5G polymorphisms and osteoporosis in a population of Turkish women. METHODS: A total of 195 postmenopausal female patients who were diagnosed with osteoporosis (Group I) based on bone mineral density measurements via dual-energy x-ray absorptiometry and 90 females with no osteoporosis (Group II) were included in this study. Correlations between PAI-1 gene 4G/5G polymorphisms and osteoporosis were investigated through the identification of PAI-1 gene 4G/5G polymorphism genotypes using the polymerase chain reaction. RESULTS: No significant differences in the genotype and allele frequency of 4G/5G plasminogen activator inhibitor type-1 polymorphisms were observed between the two groups, and both groups exhibited the most frequently observed 4G5G genotype. CONCLUSION: No correlation between the development of osteoporosis in the female Turkish population and 4G/5G plasminogen activator inhibitor type-1 gene polymorphisms was observed. PMID:23184207

A Turkish version of Kogan's attitude toward older people (KAOP) scale: reliability and validity assessment.  

PubMed

The considerable growth in the elderly population in Turkey has brought with it problems as well as concerns regarding gerontological education for health care professionals. The quality of care provided for older people is directly related to the attitudes of health care professionals. Validated instruments are needed in order to study attitudes toward old people. Aim of this study was to assess the reliability and validity of a Turkish version of KAOP among faculty of health sciences (health management, nutrition and dietetics, nursing, physical therapy, social workers and sports) students (n=594) at a university. The scale was translated using the back-translation technique. A two-phase data collection design was used. Four weeks following the first completion, another KAOP form was given. Content validity, construct validity, internal consistency, and stability reliability were assessed. Scores were between 86 and 175. The study sample reported slightly positive attitudes (132.9 ± 14.74). All of the 34 items were found to have significant item-to-total correlations. The content validity index was 0.94. The Cronbach's alpha was 0.84 for the total scale. The Turkish version of the KAOP can be considered reliable and valid scale for assessing the attitudes toward older people. PMID:21075461

Materials and Methods: The pre-treatment orthodontic records of 2530 patients, 1382 girls (54.62%) and 1148 boys (45.38%) between the chronological ages of 7 and 16 years, were examined for evidence of hypodontia. The third molars were excluded in this study. Results: The prevalence of hypodontia in the inspected population was 5% (3.05% for girls, 1.95% for boys). The average number of the congenitally missing teeth per patient was 2.03 (1.08 for girls, 0.95 for boys). The prevalence of the congenitally missing permanent teeth was 34% for the upper laterals, 30% for the lower second premolars, 12.5% for the upper second premolars and 23.5% for the other teeth. Most patients with hypodontia (84.9%) (57.13% for girls, 27.77% for boys) had got missing either one tooth (45.23%) or two teeth (39.67%). Conclusions: The prevalence of hypodontia in girls was higher than in boys in this sample of the Turkish patients. The upper laterals and lower second premolars were consecutively the most symmetrically absent teeth. The prevalence of advanced hypodontia was lower than single and symmetrical hypodontia.

A Study on Olfactory Dysfunction in Turkish Population with using Survey Method and Validated Olfactory Testing.  

PubMed

The aim of this study was to evaluate the effect of olfactory dysfunction on quality of life (QOL), and to investigate olfactory dysfunction related self-reported clinical features in Turkish population. The participants were questioned about the presence of any olfactory dysfunction. Participants with a complaint of olfactory dysfunction were asked to fill out a survey and then a validated olfactory test was performed. We asked 2,824 volunteers whether they had olfactory dysfunctions or not. A total of 199 (6.7 %) people mentioned that they had, and filled out the questions in our survey. The mean age of the surveyed population was 44 ± 15 years. The current investigation produced four major findings (1) the feeling of inadequacy due to olfactory dysfunction was more common among females than males (2) there was a significant correlation between subjective olfactory complaints and objective olfactory testing (3) problems in QOL issues are typically reported primarily in the areas of safety and nutrition (4) the possible reasons for the olfactory dysfunction according to the volunteers were upper respiratory infections including rhinosinusitis (46 %), allergic rhinitis (27 %), severe face and head trauma (6.5 %). The effect of subjective olfactory dysfunctions on QOL among the Turkish population was investigated for the first time. Problems in daily life issues are typically reported primarily in the areas of safety and nutrition. PMID:25621224

An investigation of retronasal testing of olfactory function in a Turkish population  

PubMed Central

Background The aim of this study was: (1) to perform a preliminary study for the validation of “retronasal olfactory testing” in the Turkish population to find the best way to evaluate smell and taste disorders in Turkey; (2) to determine if cultural differences make application of the test more difficult; and (3) to determine the flavors that participants had not yet tasted by using the survey method. Material/Methods The study included 330 volunteers. Orthonasal olfactory function was assessed psycho-physically using the “Sniffin’ Sticks” olfactory test. Retronasal olfaction was assessed using a collection of 20 available food powders applied to the oral cavity. Also, all participants filled in a questionnaire of 50 items about the flavors they had not tasted before. Results The mean age of the participants was 26±7.3 years. Participants were divided into 3 groups according to the “Sniffin’ Sticks” test results: anosmia, hyposmia, and normosmia groups. Differences in retronasal olfaction scores were significant among the 3 groups. Conclusions The retronasal olfactory test appeared to perform well, but modifications of odorized powders or granules and distracters used in the retronasal olfactory test, taking into account Turkish cultural differences, is likely to improve its performance.

A model linking sources of stress to approach and avoidance coping styles of Turkish basketball referees.  

PubMed

Purpose of this study was to externally validate and test a conceptual transient model involving six paths that linked sources of acute stress to avoidance and approach coping styles among Turkish basketball referees. The sample consisted of 125 Turkish basketball referees ranging in age from 18 to 36 years (mean = 25.58. ? = 3.69). The path analysis tested the relationships simultaneously from stressors, in consecutive order, distractions, subpar performance and verbal abuse, to coping styles, first both avoidance-cognitive and approach-cognitive, and then approach-behaviour. Results indicated that the model achieved a good fit and that all paths tested simultaneously were significant. The distractions stressor was positively related to subpar performance, which, in turn, was positively related to verbal abuse. Verbal abuse was negatively associated with an avoidance-cognitive coping style and positively related to the approach-cognitive coping style. The results also supported a crossover effect of both avoidance-cognitive and approach-cognitive on approach-behaviour. One implication of this study is that coping should be studied in naturally occurring stages, a process-oriented approach. Another implication is that approach and avoidance coping styles, each sub-divided into cognitive and behavioural categories, provide a meaningful framework which provides sports officials a coherent structure for learning and improving ways to cope with acute stress experienced during the contest.

Achievement motivation and academic performance among Turkish early and young adolescents in The Netherlands.  

PubMed

The authors conducted 3 studies in which Turkish and other adolescents in the Netherlands completed questionnaires that addressed the importance of collectivist cultural values for achievement motivation and educational outcomes. Compared with other minority group students and Dutch students, the Turkish students had stronger family-oriented achievement motivation. In addition, only among the Turks was ethnic identification positively related to family motivation. Furthermore, there were no differences in individual achievement motivation between the Turks and Dutch, and only among the former group was a combination of family motivation and individual motivation found. Also, for the Turks, family motivation was positively related to task-goal orientation, which mediated the relationship between family motivation and academic performance. Individual motivation was an independent predictor of performance. For the other ethnic minority groups and the Dutch, family motivation was not related to task-goal orientation and performance. In addition, for these groups, task-goal orientation mediated the relationship between individual achievement motivation and performance. PMID:11942649

Perceived discrimination, social connectedness, and other predictors of adjustment difficulties among Turkish international students.  

PubMed

This study examined the role of perceived discrimination, social connectedness, age, gender, years of study in the US, English language competency, and social contact patterns on adjustment difficulties among a sample of 229 Turkish international students studying in the United States. Findings indicated that students who reported higher levels of social connectedness, lower levels of perceived discrimination, more years of study in the US, and higher levels of English language competency reported lower levels of adjustment difficulties. Other results showed that (lack of) social connectedness and perceived discrimination were predictors of adjustment difficulties. In addition, results indicated that students who socialized with individuals from the US had lower levels of adjustment difficulties than did those who socialized with coculture members. Implications are discussed and suggestions for interventions are provided. PMID:22046992

Network centrality measures and systemic risk: An application to the Turkish financial crisis  

NASA Astrophysics Data System (ADS)

In this paper, we analyze the performance of several network centrality measures in detecting systemically important financial institutions (SIFI) using data from the Turkish Interbank market during the financial crisis in 2000. We employ various network investigation tools such as volume, transactions, links, connectivity and reciprocity to gain a clearer picture of the network topology of the interbank market. We study the main borrower role of Demirbank in the crash of the banking system with network centrality measures which are extensively used in the network theory. This ex-post analysis of the crisis shows that centrality measures perform well in identifying and monitoring systemically important financial institutions which provide useful insights for financial regulations.

Turkish meteor surveillance systems and network: Impact craters and meteorites database  

NASA Astrophysics Data System (ADS)

In our project, we aim toward constructing Turkish Meteor Surveillance Systems and Network in Turkey. For this goal, video observational systems from SonotaCo (Japan) were chosen. Meteors are going to be observed with the specific cameras, their orbits will be calculated by the software from SonotaCo, and the places where they will be falling / impacting will be examined by field trips. The collected meteorites will be investigated by IR-Raman Spectroscopic techniques and SEM-EDX analyses in order to setup a database. On the other hand, according to our Prime Ministry Ottoman Archives, there are huge amounts of reports of falls for the past centuries. In order to treat these data properly, it is obvious that processing systems should be constructed and developed.

Turkish students' scientific literacy scores: A multilevel analysis of data from Program for International Student Assessment  

NASA Astrophysics Data System (ADS)

A vast majority of the studies exploring the associations between student and school related factors and standardized test scores were conducted in developed countries. On the other hand, research suggests that the generalization of the findings of those studies to developing countries often leads to incorrect conclusions. The purpose of this study was to explore the effects of selected student- and school-level factors on 15-year old Turkish students' scientific literacy achievement. The Program for International Student Assessment (PISA) 2006 database was utilized to explore (a) if there were differences among schools in terms of their mean scientific literacy scores, (b) which student-level factors can explain the differences in students' scores within a particular school, and (c) which school-level factors can explain the scientific literacy differences between schools. Hierarchical linear modeling (HLM) method was selected as the analytic method due to its usefulness in exploring relationships between a dependent variable and sets of layered independent variables. While the dependent variable of the study was represented by five plausible scores, independent variables consisted of 25 variables. Among those predictors, 15 were measured at student-level (level 1) and grouped in 4 clusters (background characteristics, teaching and learning factors, affective factors, and out-of school science related activities), and the remaining variables were measured at level 2 and grouped under two clusters (school resources and school context). The results of the study indicated that more than half of the variation in students' scientific literacy scores occurred among schools. While eight student-level variables---grade, economic, social and cultural status, general and personal value of science, responsibility for sustainable development, science self-efficacy, in-school time spent on science learning, and hands-on activities---explained about one-third of the variation at the student-level, three school-level predictors---school sector, mean economic, social and cultural status, and mean in-school time spent on learning---accounted for more than 70% of the variation at that level. Several findings of the present study were different than what mainstream research suggested. Instrumental motivation and interest in science were found to be insignificant in predicting scientific literacy of Turkish students; while the students' perceptions about the general value of science had a positive association with scientific literacy, their perceptions on the personal value of science had a negative association. Many factors included in the teaching and learning cluster had either no relationship (investigations and interactions) or negative relationship (hands-on experiences) with the scientific literacy of Turkish students. Teacher-student ratio, lack of instructional resources, and science teacher shortage were among the non-significant predictors of Turkish students' PISA scores.

Genetic polymorphisms of 15 STR loci within Turkish student population living in Sarajevo, Bosnia and Herzegovina.  

PubMed

Allele frequencies of 15 STRs included in the PowerPlex 16 System (D3S1358, TH01, D21S11, D18S51, Penta E, D5S818, D13S317, D7S820, D16S539, CSF1PO, Penta D, VWA, D8S1179, TPOX and FGA) were calculated from the referent sample of 100 unrelated individuals of both sexes from Turkish student population living in Sarajevo, Bosnia and Herzegovina. Buccal swab, as a source of DNA, was collected from the volunteers from whom the informed consent form was obtained. DNA extraction was performed using QIAamp DNA Micro kit by Qiagen. DNA template ranging from 0.5 to 2 ng was used to amplify 15 STR loci by PCR multiplex amplification which was performed by using the PowerPlex 16 kit (Promega Corp., Madison, WI, USA) according to the manufacturer's protocol. The amplifications were carried out in a PE Gene Amp PCR System thermal cycler (Applied Biosystems) and capillary electrophoresis was carried out in an ABI PRISM 310 Genetic Analyzer (Applied Biosystems) in accordance with the manufacturer's recommendations. The frequency of each locus was calculated from the numbers of each observed genotype. Deviation from Hardy-Weinberg equilibrium and observed heterozygosity were calculated. Data were analyzed by using Microsoft Excel workbook template--Powerstats V12 and the power of discrimination (PD), power of exclusion (PE), as well as other population genetic indices for the 15 STR loci were calculated. Obtained results contribute to existing Turkish DNA database, as well as insight of differences and similarities in comparison to population of Bosnia and Herzegovina. In addition, 13 autosomal STR loci frequencies (D3S1358, TH01, D21S11, D18S51, Penta E, D5S818, D13S317, D7S820, D16S539, CSFIPO, Penta D, VWA, D8S1 179, TPOX, and FGA) were studied in 15 different worldwide populations (Turkish, Bosnian, Croatian, Serbian, Montenegrin, Macedonian, Albanian, Kosovan, Greek, Russian, Japanese, Korean, Lithuanian, Iraqi, Belarusian). For the proof of corresponding data, two different Turkish population STR data obtained from previously published articles were compared with our data and this showed that our data correspond to these 2 previously published data. Further, STR allele frequency data for 13 loci for each population were obtained from previous scientific articles and the allele frequencies and genetic diversity among the 15 sample populations were compared. In addition, even though the populations are from different nationalities, the STR data are similar among the geographically close populations. The phylogenetic tree established among worldwide populations and genetic distance values show a great affinity among the 15populations. Our data is useful for anthropological and further comparative genetic studies of populations. PMID:24611350

Abnormal eating attitudes and sexual abuse experiences in Turkish university women.  

PubMed

The aim of this study was to examine the direct and indirect relationship between abnormal eating attitudes and sexual abuse. The subject sample comprised 532 female Turkish undergraduate and nursing students in Istanbul. The Eating Attitudes Test (EAT), Sexual Abuse Questionnaire, the Setting Conditions for Anorexia Nervosa Scale, the Positive and Negative Perfectionism Scale and the Need for Control Scale (NCS) were the instruments of the study. The results showed that sexual abuse has a direct effect on EAT-Bulimia but not on EAT-Dieting. It also has some indirect effects on both of these through its effects on family functioning. Perfectionism, on the other hand, was independently linked with both EAT-Dieting and EAT-Bulimia but was not associated with sexual abuse. PMID:15656010

National (dis)identification and ethnic and religious identity: a study among Turkish-Dutch muslims.  

PubMed

National (dis)identification is examined in three studies among Turkish-Dutch Muslim participants. In explaining national (dis)identification, the first study focuses on ethnic identity, the second on ethnic and religious identity, and the third on three dimensions of religious identity. Many participants show low commitment to the nation, and many indicate national disidentification. In addition, there is very strong ethnic and religious identification. Ethnic and Muslim identifications relate negatively to Dutch identification and, in Study 3, to stronger Dutch disidentification. Furthermore, perceived group rejection is associated with increased ethnic minority and religious identification but also with decreased national Dutch identification. In addition, in Studies 1 and 2 the effect of perceived rejection on Dutch identification is (partly) mediated by minority group identification. The findings are discussed in relation to social psychological thinking about group identification, dual identities, and the importance of religion for intergroup relations. PMID:17933739

Effect of Turkish propolis extracts on proteome of prostate cancer cell line  

PubMed Central

Background Propolis is a natural, resinous hive product that has several pharmacological activities. Its composition varies depending on the vegetation, climate, season and environmental conditions of the area from where it was collected. Surface enhanced laser desorption ionization time of flight mass spectrometry (SELDI-TOF MS) is a proteomic approach which has been used in cancer proteomics studies. Prostate cancer is one of the most commonly diagnosed cancers in men. It has shown that nutritional supplements rich in polyphenolic compounds such as propolis play a significant role in prostate cancer chemoprevention. The aim of this study is to evaluate if protein expression profile in PC-3 prostate cancer cell lines could be differentiated when incubated with dimethyl sulfoxide and water extracts of Turkish propolis. Results The antioxidant potentials of dimethyl sulfoxide and water extracts of propolis were found in correlation with the amount of total phenolic compounds of them. Dimethyl sulfoxide and water extracts of propolis of 20 ?g/mL reduced the cell viability to 24.5% and 17.7%, respectively. Statistically significant discriminatory peaks between control PC-3 cells and dimethyl sulfoxide extract of propolis-treated PC-3 cells were found to be the proteomic features at m/z 5143, 8703, 12661, 20184 and 32794, detected by CM10 ProteinChip, and the peak at m/z 3772, detected by Q10 ProteinChip. Between control PC-3 cells and water extract of propolis-treated PC-3 cells, statistically significant discriminatory peaks were found to be the proteomic features at m/z 15846, 16052 and 24658, detected by CM10 ProteinChip and the peaks at m/z 10348, 10899 and 11603, detected by Q10 ProteinChip. Conclusions It was concluded that dimethyl sulfoxide and water extracts of Turkish propolis may have anti-proliferative activity through differentiating protein expression profile in PC-3 prostate cancer cell lines along with their antioxidant capacity.

Association between ADH1C and ALDH2 polymorphisms and alcoholism in a Turkish sample.  

PubMed

Background: Polymorphisms in the genes encoding alcohol metabolizing enzymes are associated with alcohol dependence. Aim: To evaluate the association between the alcohol dehydrogenase 1C (ADH1C) Ile350Val and aldehyde dehydrogenase 2 (ALDH2) Glu504Lys polymorphisms and alcohol dependence in a Turkish sample. Methods: 235 individuals (115 alcohol-dependent patients and 120 controls) were genotyped for ADH1C and ALDH2 with PCR-RFLP (polymerase chain reaction-restriction fragment length polymorphism). Association between the polymorphisms and family history, daily and maximum amount of alcohol consumed was investigated. The associations between alcohol dependence, severity of consumption and family history and the polymorphisms were analyzed by chi-square or Fisher's exact test where necessary. Relationship between genotypes and dependence related features was evaluated using analysis of variance (ANOVA). Results: The -350Val allele for ADH1C (ADH1C*2) was increased in alcohol-dependent patients (P = 0.05). In individuals with a positive family history, the genotype distribution differed significantly (P = 0.031) and more patients carried the Val allele compared with controls (P = 0.025). Genotyping of 162 participants did not reveal the -504Lys allele in ALDH2. Conclusions: These findings suggest that ADH1C*2 is associated with alcohol dependence in the Turkish population displaying a dominant inheritance model. ADH1C*2 allele may contribute to the variance in heritability of alcohol dependence. The ALDH2 -504Lys/Lys or Glu/Lys genotypes were not present in alcohol-dependent patients, similar to that seen in European populations and in contrast to the findings in the Asian populations.

Migration and change in parent-child relationships: the case of Turkish migrants in Germany.  

PubMed

The main aim of this paper is to explain the change of educational attitudes and socialization practices in Turkish migrant families by an individualistic costs-and-benefits-model and to confront this with empirical findings. This model is an interesting theoretical alternative to the widely accepted 'sociological' value-explanations stemming from the Durkheim-Parsons-Tradition. A variety of empirical detail phenomena (even) out of the domain of parent-child relationships, such as generative behavior, early childcare, educational attitudes, familial socialization, sex-typing, under varying contextual and individual conditions could be related to a common nomological core which works with few, simple basic assumptions. This explanation is mainly a more complete reconstruction of the approach contained in the studies on the 'values of children' (especially in Turkey). This reconstruction was extended to assumptions on parent-child relationships under changing familial contexts and individual conditions which result from migration. In particular, processes were emphasized which result from a combination of context opportunities and individual alternatives. The data for this study came from the research project "Socialization and Interaction in Families of Turkish Work Migrants" and was collected in 1984. 520 interviews were conducted. The empirical analysis shows once again that it is neither necessary nor meaningful to claim a special methodological or theoretical status for the explanation of behavior under migrant conditions as has often been the case for research on minorities with great cultural distance, seeking 'other' research methods as well as 'genuine' explanations. The general explanation discussed here has proved to be rather steadfast, even for cross-cultural research purposes. Nevertheless, the use of general explanations does not suspend the methodological necessity to find specifically valid indicators for the actors in the respective different situations of action. However, this general problem of empirical confirmation, which is, of course, intensified in the case of social differentiation and of cross-cultural comparisons, can be separated analytically from validity problems.

This study examined memory variables both cross-culturally and across four cultural self-construal types. US (N=240) and Turkish (N=174) college students described their earliest childhood memory, and another significant childhood memory, and completed the Balanced Integration-Differentiation (BID) Scale (Imamoglu, 1998; 2003), which measured relatedness and individuation, and allowed for the classification of students into four different self-construal types (Related-Individuated, Separated-Individuated, Related-Patterning, Separated-Patterning). At the cultural level US students' earliest memories were dated approximately 6 months earlier, had greater volume, and were more positive. US students also reported memories as more important. Turkish students' memories had more detail, a higher proportion of propositions, self-, other- and we-related words, and higher other-self ratios, and they were clearer than those of US students. Turkish students also reported greater ease in describing their earliest memory in words. At the level of self-construal the primary differences were between students high in both relatedness and individuation and those low in both. The culture by BID interaction was significant in only 1 of the more than 24 analyses. PMID:23452078

Frequency of the Methylenetetrahydrofolate REDUCTASE 677CT and 1298AC mutations in an Iranian Turkish female population  

PubMed Central

ABSTRACT Introduction: Gene-environmental interactions in the pathway of folate metabolism influence greatly the embryonic development. Individual specific MTHFR 677C/T and 1298A/C mutations are known as risk factors for predisposition to human disorders. Therefore, we studied the frequencies of the MTHFR 677CT and 1298AC mutations in a female general population from Iranian Azeri Turkish. Material and methods: We studied 108 unrelated women from Iranian Azeri Turkish general population. Genomic DNA was extracted using standard procedure. The MTHFR 677CT and 1298AC mutations determined by PCR-RFLP method. Outcomes: The frequencies (percent) at position 677 for C and T alleles were 159(74%), 57(26%), and for CC, CT, and TT genotypes were 59(54.6%), 41(38%), and 8(7.41%) respectively. The frequencies (percent) at position 1298 for A and C alleles were 136(63%), 80(37%), and for AA, AC, and CC genotypes were 43(39.8%), 50(46.3%), and 15(13.9%) respectively. Conclusions: The frequency of MTHFR 677 C and T alleles were 0.74 and 0.26 while that of MTHFR 1298 A and C alleles were 0.63 and 0.37 in present study, respectively. This is the first report in its own kind in Iranian Azeri Turkish women. PMID:21977149

Prevalence of nonvitamin, nonmineral supplement usage among students in a Turkish university  

PubMed Central

Background There have been multiple studies carried out in many countries with regard to the use of nonvitamin, nonmineral (NVNM) supplements. These studies have shown that the use of NVNM supplements is on the increase throughout the world, particularly in western countries. The aim of this study was to assess the extent of NVNM supplement use among Turkish university students. Methods The survey was conducted between September and December 2004 at Osmangazi University, a public university located in the west of Turkey. Responses were analysed, using the chi-square (x2) test, t test and percent (%) ratios, according to gender and consumers. Differences were considered significant for p ? 0.05. Results Of 2253 students attending the university, 1871 participated in the survey (909 men and 962 women). Overall, the prevalence of NVNM supplement use was 16.5% (16.6% in men and 16.3% in women, p < 0.05). The three most commonly given reasons for use were 'improvement of energy and vitality (78.6%)', 'promotion of weight loss (71.1%)', followed by 'enhancement of athletic performance (64.3%)'. Twenty-six of the 308 reported NVNM users (26/308, 8.4%) reported having experienced an adverse reaction. Television (76.3%), magazines/newspapers (41.5%) and internet websites (37.3%) were the most frequently used sources for obtaining information about NVNM supplements. The three most frequently used NVNM supplements were echinacea, ginseng, and gingko biloba (38.6%, 36.4%, and 32.8%, respectively). Nutritional scores were higher in NVNM supplement users than in non-users (66.510.8 vs. 62.712.7) (p < 0.001). Users and nonusers of NVNM supplements differed significantly according to sex, age, Body Mass Index (BMI) values, types of school, mother and fathers' education levels, family income, most permanent place of residence up to the time of survey, smoking status, and participating in sports. Conclusion The results indicate that the prevalence of NVNM supplement use is relatively modest among Turkish university students and more information is needed on why people use particular NVNM supplements.

Exercise stages of change in Turkish university students by sex, residence, and department.  

PubMed

To examine the exercise behavior of 953 Turkish university students (496 men, 457 women) by sex, residence, and department of study, a stratified sampling method, based on the total number of students in each department, was used to select participants. The mean age of the participants was 21.3 yr. (SD = 1.9). For completed Physical Activity Stages of Change Questionnaire and the International Physical Activity Questionnaire, descriptive statistics and chi-squared tests indicated that most students were at the lower stages of change in exercise habits: Precontemplation (15.2%), Contemplation (31.4%), and Preparation (25.3%), compared with the later stages of Action (7.5%) and Maintenance (20.6%). Women and students from the Department of Architecture were at lower stages of change than men and students from other departments (p < .05), but there were no significant differences between students who were living on or off campus. Stage-based interventions would be appropriate, with focus on the physical activity of women and students in architecture. PMID:19544946

Two new ?-thalassemia deletions compromising prenatal diagnosis in an Italian and a Turkish couple seeking prevention  

PubMed Central

When the molecular background of couples requesting prevention is unclear, family analysis and tools to define rare mutations are essential. We report two novel deletion defects observed in an Italian and in a Turkish couple. The first proband presented with microcytic hypochromic parameters without iron deficiency, a normal HbA2 and an elevated HbF (10.6%). His father presented with a similar phenotype and his wife was heterozygous for the common Mediterranean codon 39 (HBB:c.118C>T) mutation. Having excluded point mutations and common deletions, Multiplex Ligation-dependent Probe Amplification was performed revealing an unknown G?(A???)0-thalassemia defect spanning from the A? gene to downstream of the ?-globin gene provisionally named Leiden 69.5 kb deletion. In the second case, the wife presented with a mild thalassemic picture, normal HbA2, elevated HbF (18.5%) and a ?/? globin chain synthesis ratio of 0.62, without iron deficiency or any known ?-thalassemia defect, while the husband was a simple carrier of the common Mediterranean IVS-I-110 (HBB:c.93-21 G>A) mutation. A new large deletion involving the ?-gene and part of the ?-gene was identified by Multiplex Ligation-dependent Probe Amplification provisionally named “Leiden 7.4 kb”. PMID:19734421

Single-step purification of peroxidase by 4-aminobenzohydrazide from Turkish blackradish and Turnip roots.  

PubMed

Peroxidases (PODs) were purified from the Turkish blackradish (Raphanus sativus L.) (TBR) and Turnip (Brassica rapa L.) using a simple and effective single-step method. An affinity resin was synthesised by coupling the 4-aminobenzohydrazide ligand and the l-tyrosine spacer-arm to CNBr-activated-Sepharose-4B. The purification factors for the TBR-POD and the Turnip-POD were 40.3-fold (with a yield of 10.6%) and 269.3-fold (with a yield of 9%), respectively. The molecular masses of the TBR-POD and Turnip-POD were approximately 67.3 and 65.8kDa, respectively. For guaiacol, the Km and Vmax values were calculated as 24.88mM and 3.23EU/mL, respectively for TBR-POD and as 4.09mM and 0.797EU/mL for the Turnip-POD. For H2O2, the Km and Vmax values were calculated as 3.247mM and 0.799EU/mL, respectively for TBR-POD, and as 12.49mM and 4.055EU/mL, respectively for the Turnip-POD. Furthermore, 4-aminobenzohydrazide was determined to be a non-competitive inhibitor of TBR-POD and Turnip-POD. PMID:24360459

Effect of PON1 gene polymorphisms in Turkish patients with hepatocellular carcinoma?  

PubMed Central

Background: Reactive oxygen species (ROS) can oxidize biological molecules that mediate carcinogenesis by causing metabolic malfunction and damage to DNA. Human serum paraoxonases (PON1, PON2 and PON3) play a role in antioxidant defense and protect the cell against ROS. PON1 polymorphisms Q192R and L55M have been shown to be associated with several human cancers, but their association with hepatocellular carcinoma (HCC) has yet to be investigated. Methods: We performed genotyping analysis using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay in a hospital-based case–control study of 217 confirmed HCC patients and 217 age-, gender-, smoking- and alcohol consumption-matched cancer-free controls in Turkish population. Results: Q192R and L55M polymorphisms were in significant linkage disequilibrium (LD) (D? = 0.77). However, allele, genotype and haplotype analysis showed no significant differences between the risks of HCC and PON1 polymorphisms. Moreover, no significant differences were found between clinical findings, clinicopathological features and sex in comparison with the PON1 genotypes in HCC group. Conclusion: Our results suggest for the first time that neither the Q192R polymorphism nor the L55M polymorphism has relationship with the risk of developing HCC. Further independent studies are required to clarify the possible role of PON1 gene Q192R and L55M polymorphisms on the risk of developing HCC in a larger series and also in patients of different ethnic origins.

Radiometric analysis of raw materials and end products in the Turkish ceramics industry  

NASA Astrophysics Data System (ADS)

This study presents the findings of radiometric analysis carried out to determine the activity concentrations of natural radionuclides in raw materials (clay, kaolin, quartz, feldspar, dolomite, alumina, bauxite, zirconium minerals, red mud and frit) and end products (glazed ceramic wall and floor tiles) in the Turkish ceramics industry. Hundred forty-six samples were obtained from various manufacturers and suppliers throughout the country and analyzed using gamma-ray spectrometer with HPGe detectors. Radiological parameters such as radium equivalent activity, activity concentration index and alpha index were calculated to assess the radiological aspects of the use of the ceramic end products as decorative or covering materials in construction sector. Results obtained were examined in the light of the relevant national and international legislation and guidance and compared with the results of similar studies reported in different countries. The results suggest that the use of ceramic end product samples examined in the construction of dwellings, workplaces and industrial buildings in Turkey is unlikely to give rise to any significant radiation exposure to the occupants.

Polycyclic aromatic hydrocarbons (PAHs) in sea sediments of the Turkish Mediterranean coast, composition and sources.  

PubMed

The concentrations of polycyclic aromatic hydrocarbons (PAHs) were determined in 25 surface sediment samples from five sites located at Oludeniz Lagoon of the Turkish Mediterranean coast. The total concentration of the PAHs (1.85?±?1.39 mg/kg) was lower than the sediments from highly urbanized areas, while it was comparable with the sediments from similar locations. Acenaphthene and chrysene were dominant ones with the concentrations of 0.620 and 0.515 mg/kg, respectively. The isomeric ratios indicated that combustion is the predominant source of PAHs in the sediments. Factor analysis solution supports the same finding with three major factors accounting for 71.7 % of the variability in the data. Factor 1 with 43.4 % of the total variance identified as a pyrogenic source (coal combustion; 4 rings PAH and traffic related pollution; 5-6 rings PAHs). Factor 2 (explains 39 % of the total variance) represents PAHs originating from traffic, and factor 3 (explains 12 % of the total variance) represents petrogenic source. Our results suggest that combustion of fossil fuels affects most of the points, followed by combustion of biomass and human activity. PMID:25280504

Molecular and clinical evaluation of Turkish patients with lysinuric protein intolerance.  

PubMed

Lysinuric protein intolerance is an autosomal recessive metabolic disorder caused by defective transport of the cationic amino acids lysine, arginine and ornithine in the epithelial cells of the basolateral membrane in the small intestine and renal tubules. Mutations in the solute carrier family 7, member 7, SLC7A7, gene cause this multisystemic disease with a variety of clinical symptoms such as hepatosplenomegaly, osteoporosis, hypotonia, developmental delay, pulmonary insufficiency or end-stage renal disease. In the present study, genomic structure of SLC7A7 in six Turkish patients with lysinuric protein intolerance was examined in order to detect disease causing mutations by denaturing high pressure liquid chromatography and direct sequencing. Four novel mutations were identified in SLC7A7: c.223insGTC, p.Val74_Ile75insVal; c.283insTGG, p.Glu94_Thr95insTrp; c.344_347delTTGC, p.Leu115LeufsX53; and c.1099insT, p.Ile367TyrfsX16. Clinical and biochemical findings were evaluated together with these molecular analyses. PMID:23542076

Genotyping and Phylogenetic Analysis of Giardia duodenalis Isolates from Turkish Children.  

PubMed

Background Giardiasis is caused by the intestinal protozoan parasite Giardia duodenalis (synonyms: G. lamblia, G. intestinalis), which is one of the most frequent parasites that infect Turkish children. However, molecular characterization of G. duodenalis in Turkey is relatively scarce. The present work aimed at genotyping G. duodenalis isolates from Turkey using molecular techniques. Material and Methods In the present study, 145 fecal samples from children were collected to search for the presence of Giardia by microscopy and PCR screening. PCR generated a 384 bp fragment for ?-giardin. The PCR products were sequenced and the sequences were subjected to phylogenetic analysis by using PHYLIP. Results Based on the phylogenetic analysis of the sequences, assemblage A, B, and mixed subtypes were determined. Of 22 isolates, 11 were identified as assemblage A (50%), 7 were assemblage B (31.8%), and 4 were assemblage AB (18.2%). Association between G. duodenalis assemblages and the epidemiological data was analyzed. No correlation was found between symptoms and infection with specific assemblages (P>0.05), but we found statistically significant association between age and the assemblage AB (P=0.001). Conclusions The association between G. duodenalis and the epidemiologic data were analyzed. Since assemblage A is the more prevalent subgroup compared with assemblage B, this subgroup might be responsible for common Giardia infections in Turkey. This is the first study that included a detailed phylogenetic analysis of Giardia strains from Turkey. PMID:25689970

Survival of Helicobacter pylori in Turkish fermented sucuk and heat-treated sucuk during production.  

PubMed

The aim of this study was to investigate the survival of Helicobacter pylori during production of sucuk (Turkish fermented sausage). The sucuk mixture was inoculated with H. pylori ATCC 43504 to produce a final level in the mixture of ?5 × 10(6) CFU/g. Samples in group I were fermented and dried traditionally at 22°C for 7 days. Samples in groups II and III were subjected to the traditional fermentation at 22°C for 3 days. After fermentation, group II samples were fermented and dried at 35°C for 4 days and group III samples were treated with heat until the core temperature reached 65°C. On the first day of fermentation, a 1-log reduction in H. pylori was found in all groups. The H. pylori levels in all groups increased by about 1 log CFU/g by the third day of fermentation and reached the inoculation level. On the fifth and seventh days of fermentation, no appreciable change occurred in the level of H. pylori in groups I and II. After heat treatment, the H. pylori levels were below the level of detection. These results suggest that H. pylori can grow during sucuk fermentation and that a heat treatment should be used during sucuk processing to destroy H. pylori. PMID:22186045

Patterns of collaboration in four scientific disciplines of the Turkish collaboration network  

NASA Astrophysics Data System (ADS)

Scientific collaboration networks, as a prototype of complex evolving networks, are studied in many aspects of their structure and evolving characteristics. The organizing principles of these networks also vary in different scientific disciplines, demonstrating that each discipline has specific connecting rules. Retrieving the co-authorship data from the ISI Web of Science, we constructed networks of four disciplines (engineering, mathematics, physics and surgery) as a subset of the Turkish scientific collaboration network spanning 33 years’ data. To provide a comparative perspective on the network topologies, we studied some statistical and topological properties such as the number of authors, degree distributions, authors per paper and papers per author histograms and distributions. These properties yield that the rapid growth of high education in Turkey (i.e. doubling of the number of universities and students within the last decade) had boosted the number of publications and increased the level of collaborations in the scientific collaboration networks. We showed the occurrence of Matthew effect in career longevity distributions, and also outlined the Heaps’ law relation in the scaling of the collaborations as well. We outlined the prominent properties of each subset, while the similarities and deviations from the interdisciplinary networks are also evaluated.

Ecosystem Structure Changes in the Turkish Seas as a Response to Overfishing  

NASA Astrophysics Data System (ADS)

Human population in Turkey has grown more than five-fold since its establishment in 1923 and more than 73 million people are currently living in the country. Turkey is surrounded by partially connected seas (the Black Sea, the Sea of Marmara, the Aegean Sea and the Mediterranean Sea) each of which has significantly different productivity levels and ecosystem characteristics. Increasing human population with its growing socio-economic needs has generated an intensive fishing pressure on the fish stocks in its exclusive economic zone. Fishing grounds in the surrounding seas were exploited with different fishing intensities depending upon their productivity level and catch rates. Hence, the responses of these different ecosystems to overfishing have been realized differently. In this study, changes of the ecosystem structures in the Turkish Seas were comparatively investigated by ecosystem indices such as Marine Trophic Index (MTI), Fishing in Balance (FiB) and Primary Production Required (PPR) to assess the degree of sustainability of the fish stocks for future generations.

Growth reference centiles and secular changes in Turkish children and adolescents.  

PubMed

The purpose of the study is to develop current reference growth centiles for Turkish children and adolescents. A cross-sectional growth survey was conducted on 1.427 (709 boys and 718 girls) healthy schoolchildren aged 6-17 years in Ankara, the capital city of Turkey. As an indicator of socio-economic status, the occupation of the parents was recorded. Growth references of height, weight, body mass index (BMI), sitting height, iliospinal height, relative iliospinal height and relative sitting height were constructed by the LMS method. Sex differences, association of parental occupation with height and BMI standard deviation scores were assessed by analyses of variance. Results showed significant sexual dimorphism for height, weight, sitting height and iliospinal height (p<0.001). Significant effect of socio-economic background was found on height and BMI. The prevalence of overweight and obesity was found using the International Obesity Task Force (IOTF) reference criteria 22.4% and 5.6% in boys and 21.2% and 3% in girls. Present results demonstrated an increment during the last three decades in height, leg length and weight curves which is more prominent in boys, but not in the sitting height. This positive secular change appears to be a logical outcome of the gradual changes in nutrition, health care and education, and environmental and economic conditions. PMID:17475574

Respiratory health symptoms among students exposed to different levels of air pollution in a Turkish city.  

PubMed

In this study, we aimed to investigate the frequency of respiratory health symptoms among high school students attending schools at industrial, urban and rural areas in a Turkish city. Three schools located in different zones of the city having different pollution characteristics were chosen based on the pollutant distribution maps using Geographical Information Systems (GIS) software. A cross-sectional survey was performed among 667 high school students in the schools. Outdoor and indoor nitrogen dioxide (NO(2)) and ozone (O(3)) concentrations were also measured by passive samplers in the same schools to investigate possible routes of exposure. Chronic pulmonary disease (OR = 1.49; 95%CI: 1.11-1.99; p = 0.008), tightness in the chest (OR = 1.57; 95%CI: 1.22-2.02; p = 0.001), morning cough (OR = 1.81 95%CI: 1.19-2.75; p = 0.006) were higher among students in the industrial zone where nitrogen dioxide and ozone levels were also highest. There were no indoor sources of nitrogen dioxide and ozone exists in the schools except for the dining hall. As a conclusion, this study has noticed that air pollution and respiratory health problems among high school students are high in industrial zones and the use of passive samplers combined with GIS is an effective tool that may be used by public health researchers to identify pollutant zones and persons at risk.

Extramedullary Plasmacytoma of the Frontal Sinus: Case Report and Turkish Literature Review  

PubMed Central

Solitary extramedullary plasmacytomas (EMPs) are nonepithelial neoplasms of plasma cell origin categorized among non-Hodgkin lymphomas, without the bone marrow involvement and systemic spread seen in multiple myeloma. They are uncommon tumors comprising 3% of all plasma cell neoplasias. Although they usually occur in the upper respiratory tract, only 1 case of EMP localized to the frontal sinus has been reported in the English literature. We present in this report a rare case of EMP originated from the left frontal sinus leading to left eyeball proptosis and movement restriction. A survey of sinonasal EMPs in the Turkish literature is reported, as well. Paranasal computerized tomography and magnetic resonance imaging of a 69-year-old female who presented with left eyeball proptosis and left-sided headache revealed a solid mass in the left frontal sinus. Histopathological analysis of the completely excised mass supported the diagnosis of plasmacytoma. The definitive diagnosis of solitary EMP was confirmed with further investigations at hematology and oncology clinics. The patient was treated with surgery followed by local radiotherapy to the head and neck region, and she was disease-free at her 1-year follow-up. Treatment of sinonasal EMP is surgery alone or surgery combined with radiotherapy. Long-term follow-up is a requisite for systemic control because of the disease’s high potential to transform into multiple myeloma. PMID:25330525

A standardized set of 260 pictures for Turkish: norms of name and image agreement, age of acquisition, visual complexity, and conceptual familiarity.  

PubMed

In the present study, normative data in Turkish are presented for the 260 color versions of the original Snodgrass and Vanderwart (1980) picture set for the first time. Norms are reported for name and image agreement, age of acquisition (AoA), visual complexity, and conceptual familiarity, together with written word frequency, and numbers of letters and syllables. We collected data from 277 native Turkish adults in a variety of tasks. The results indicated that, whilst several measures displayed language-specific variation, we also reported what seem to be language-independent-that is, universal-measures that show a systematic relationship across several languages. The implications of the reported measures in the domain of psycholinguistic research in Turkish and for wider cross-linguistic comparisons are discussed. PMID:23943583

Psychometric evaluation of the Turkish version of the Zarit Burden Interview in family caregivers of inpatients in medical and surgical clinics.  

PubMed

The aim of this study was to adapt the Zarit Burden Interview (ZBI) to family caregivers of inpatients in medical and surgical clinics to assess the validity and reliability of the Turkish version. The study design was descriptive and methodological. A total of 223 family caregivers providing care to patients for at least 1 week in clinics were selected through convenience sampling. Data were collected using the Turkish translation of the ZBI. The psychometric testing of the adapted instrument was carried out to establish internal consistency, interitem correlation, and construct validity. The content validity procedure resulted in a final scale comprising 18 items. Cronbach's alpha was .82. Factor analysis yielded one factor. The Turkish version of the ZBI adapted to the clinics can be used as a one-factor tool. PMID:22228779

Cognitive and language skills of Turkish children in Germany: a comparison of the second and third generation and mixed generational groups.  

PubMed

The paper compares several generational groups of Turkish children in Germany with respect to cognitive skills and German language skills at an early age. Empirically, children of inter-marriages outperform the other groups of Turkish children in both tests while children with a first generation mother and a second generation father score worse than all others. All group differences regarding children’s cognitive skills can be explained by the families’ socio-economic status and educational resources. In contrast, with respect to children’s language skills also parents’ endowment with receiving country specific resources (e.g., parental German language proficiency) needs to be taken into account.

Incidence of End-Stage Renal Disease in the Turkish-Cypriot Population of Northern Cyprus: A Population Based Study  

PubMed Central

Background This is the first report of the incidence and causes of end-stage renal disease (ESRD) of the Turkish-Cypriot population in Northern Cyprus. Methods Data were collected over eight consecutive years (2004–2011) from all those starting renal replacement therapy (RRT) in this population. Crude and age-standardised incidence at 90 days was calculated and comparisons made with other national registries. We collected DNA from the entire prevalent population. As an initial experiment we looked for two genetic causes of ESRD that have been reported in Greek Cypriots. Results Crude and age-standardised incidence at 90 days was 234 and 327 per million population (pmp) per year, respectively. The mean age was 63, and 62% were male. The age-adjusted prevalence of RRT in Turkish-Cypriots was 1543 pmp on 01/01/2011. The incidence of RRT is higher than other countries reporting to the European Renal Association – European Dialysis and Transplant Association, with the exception of Turkey. Diabetes is a major cause of ESRD in those under 65, accounting for 36% of incident cases followed by 30% with uncertain aetiology. 18% of the incident population had a family history of ESRD. We identified two families with thin basement membrane nephropathy caused by a mutation in COL4A3, but no new cases of CFHR5 nephropathy. Conclusions This study provides the first estimate of RRT incidence in the Turkish-Cypriot population, describes the contribution of different underlying diagnoses to ESRD, and provides a basis for healthcare policy planning.

The needs of insufficiently treated Turkish patients motivated to offer a group-psychotherapy in cooperation with an interpreter. Only on a trickful way his expenses could be paid by the health insurance. While the plan for such a group was made, it was estimated just as a second-rate escape for such patients. But already during the course of the first group-session a therapeutic concept developed which overcame barriers of language and culture. So this experiment turned out to be an important step for developing suitable therapeutic structures for migrants. PMID:7675902

Association between gene polymorphisms in TIM1, TSLP, IL18R1 and childhood asthma in Turkish population  

PubMed Central

Many immunologic and inflammatory mechanisms play a role in asthma etiology. The aim of this study was to investigate the susceptibility of asthma patients in the Turkish population with demonstrating genes for polymorphisms in TIM1, TSLP and IL18R1. All of the genomic DNA samples were isolated from blood samples according to a standard salting-out protocol. DNA samples were stored at -20°C until the genotype analysis was performed. rs3806933 (TSLP -847 C > T) and TIM1 -416G > C were analyzed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The rs3806933 (TSLP -847 C > T) was genotyped by PCR using our new primers and HphI restriction enzyme digestion. rs2287033 (IL18R1 c. 1270+150 A > G), rs3213733 (IL18R1 c. 626-196 G > T), and rs3771166 (IL18R1- c. 302+1694 C > T) were genotyped using SYBR green dye based real time PCR assay. Results: The allele frequencies of 5 SNPs in TSLP, TIM-1, and IL18R1 genes were determined in 139 asthmatic patients and 126 healthy controls of in Turkish population. The investigated SNPs are as follows; rs3806933 (TSLP -847 C > T), TIM1 -416G > C, rs2287033 (IL18R1 c. 1270+150 A > G), rs3213733 (IL18R1 c. 626-196 G > T), and rs3771166 (IL18R1- c. 302+1694 C > T). Results suggest that IL18R1 c. 626-196 G > T (rs3213733) and TIM1 -416G > C are significantly associated with asthma in patients in Turkish population. Patients with AA genotypes of rs2287033 (IL18R1 c. 1270+150 A > G), have significantly less total serum IgE levels when compared with patients having GG or GA genotypes (p < 0.012; 381.77±239.46 vs 557.52±549.96, respectively). Conclusion: This study showed that IL18R1 c. 626 -196 G > T (rs3213733) and TIM1 -416G > C are significantly associated with asthma patients in Turkish population. PMID:24955184

Genotype and allele frequencies of divalent metal transporter 1 polymorphism in Turkish population.  

PubMed

Divalent metal transporter 1 (DMT1 also known as DCT1, NRAMP2 or SCL11A2) is a membrane-bound divalent metal transporter which is conserved from prokaryotes to higher eukaryotes. It has been postulated to play important roles in intestinal iron absorption at the brush border of duodenal enterocytes, erythroid iron utilization, hepatic iron accumulation, placental iron transfer, and other processes. DMT1 gene which contains at least four isoforms (1A/+IRE, 1A/-IRE, 2/+IRE and 2/-IRE) is located on chromosome 12q13 in human. DMT1 mediates the transport of a wide range of metals, including the essential metals Fe2+, Zn2+, Mn2+, Cu2+, Co2+, Ni2+ and toxic metals such as Cd2+ and Pb2+. The intention of this study is to determine that IVS4+44C/A single nucleotide polymorphism in DMT1 gene of Turkish population. For this purpose blood samples from 192 female and 192 male volunteers were analyzed. DMT1 gene was amplified with the polymerase chain reaction-restriction fragment length polymorphism technique and 351 bp oligonucleotide was produced. The amplified oligonucleotides were cut with MnlI restriction enzyme according to their polymorphic characteristics. Digested and undigested products were separated on a 2% agarose gel electrophoresis, visualized by ethidium bromide staining under an ultraviolet illuminator. The genotype frequencies of DMT1 IVS4+44C/A polymorphism were determined as 47.9% for CC, 40.1% for AC and 12.0% for AA genotypes. The frequency of the C allele was found to as 68.0% and of the A allele as 32.0%. The genotype frequencies were consistent with Hardy-Weinberg equilibrium (?2=2.394; Exact P=0.128). PMID:21104143

Comparison of missing value imputation methods in time series: the case of Turkish meteorological data  

NASA Astrophysics Data System (ADS)

This study aims to compare several imputation methods to complete the missing values of spatio-temporal meteorological time series. To this end, six imputation methods are assessed with respect to various criteria including accuracy, robustness, precision, and efficiency for artificially created missing data in monthly total precipitation and mean temperature series obtained from the Turkish State Meteorological Service. Of these methods, simple arithmetic average, normal ratio (NR), and NR weighted with correlations comprise the simple ones, whereas multilayer perceptron type neural network and multiple imputation strategy adopted by Monte Carlo Markov Chain based on expectation-maximization (EM-MCMC) are computationally intensive ones. In addition, we propose a modification on the EM-MCMC method. Besides using a conventional accuracy measure based on squared errors, we also suggest the correlation dimension (CD) technique of nonlinear dynamic time series analysis which takes spatio-temporal dependencies into account for evaluating imputation performances. Depending on the detailed graphical and quantitative analysis, it can be said that although computational methods, particularly EM-MCMC method, are computationally inefficient, they seem favorable for imputation of meteorological time series with respect to different missingness periods considering both measures and both series studied. To conclude, using the EM-MCMC algorithm for imputing missing values before conducting any statistical analyses of meteorological data will definitely decrease the amount of uncertainty and give more robust results. Moreover, the CD measure can be suggested for the performance evaluation of missing data imputation particularly with computational methods since it gives more precise results in meteorological time series.

Antihypercholesterolaemic and antioxidant activity assessment of some plants used as remedy in Turkish folk medicine.  

PubMed

Ethanolic and aqueous extracts from five plant species used in Turkish traditional medicine were evaluated for in vivo hypercholesterolaemic and antioxidant activities: Agrostemma githago L., Potentilla reptans L., Thymbra spicata var. spicata L., Urtica dioica L. and Viscum album var. album L. We assayed the effects of the administration of plant extracts on serum total cholesterol, triglyceride, HDL-C, LDL-C, glucose, AST and ALT concentrations in mice fed with cholesterol-rich diet. In addition, plasma TAA, MDA and NO(x) levels in the same animals were assayed. All the aqueous plant extracts did not affect the serum cholesterol concentration. However, the ethanolic extracts of Agrostemma githago, Thymbra spicata and Viscum album decreased the serum cholesterol concentration in the mice fed with high-cholesterol diet without inducing any gastric damage. The ethanolic extracts of Thymbra spicata, Viscum album, Potentilla reptans and Urtica dioica and the aqueous extract of Agrostemma githago increased the serum HDL concentration, whereas the ethanolic extracts of Agrostemma githago, Thymbra spicata, Viscum album and Urtica dioica decreased the serum LDL-C concentration. Thymbra spicata and Viscum album were observed to decrease the serum triglyceride concentration. Among the plant extracts studied, the ethanolic extracts of Thymbra spicata significantly decreased the MDA level in mice. The ethanolic extract of Potentilla reptans increased in NO(x). None of these plants showed statistically prominent activity on plasma TAA. Results of the present study indicated that the ethanolic extracts of Agrostemma githago, Thymbra spicata and Viscum album showed potent hypocholesterolaemic activity in the mice fed with a diet containing high-cholesterol.

Comparison of Chosen Physical Fitness Characteristics of Turkish Professional Basketball Players by Division and Playing Position  

PubMed Central

The purpose of the present study was to compare chosen physical fitness characteristics of Turkish professional basketball players in different divisions (first and second division) and playing positions. Forty-five professional male basketball players (14 guards, 15 forwards, 16 centers) participated in this study voluntarily. For each player, anthropometric measurements were performed, as well as a multi-stage 20 m shuttle run, isokinetic leg strength, squat jump (SJ), countermovement jump (CMJ), 10–30 meter single-sprint and T-drill agility tests. The differences in terms of division were evaluated by independent t-test and the differences by playing position were evaluated by one-way ANOVA with Post Hoc Tukey test. First division players’ CMJ measurements were significantly higher than those of second division players’ (p?0.05), whereas second division players’ 10 m sprint times were significantly better than those of first division players’ (p?0.05). In addition, forwards and centers were significantly taller than guards. Centers were significantly heavier and their T-drill test performances were inferior to those of forwards and guards (p?0.05). Moreover, guards had a significantly higher maximal oxygen uptake (VO2 max) than centers. Guards and forwards showed significantly better performance in the 10 and 30 m sprint tests than centers (p?0.05). Forwards and centers had significantly better left leg flexor strength at 180°.s?1(p?0.05). In conclusion, the findings of the present study indicated that physical performance of professional basketball players differed among guards, forwards and centers, whereas there were not significant differences between first and second division players. According to the present study, court positions have different demands and physical attributes which are specific to each playing position in professional basketball players. Therefore, these results suggest that coaches should tailor fitness programs according to specific positions on the court. PMID:23486863

A Population-Based Study of Factors Associated With Nocturia in Reproductive-Aged Turkish Women  

PubMed Central

Purpose This study aimed to investigate the prevalence of nocturia according to the International Continence Society (ICS) definition in Turkish women and to determine the associated risk factors and the correlation of other voiding symptoms with nocturia. Materials and Methods A prospective epidemiological study was carried out by use of self-reported questionnaires in 4,250 reproductive-aged women from January 2013 to May 2013. The International Consultation on Incontinence Questionnaire-Short Form and a questionnaire developed by the researchers according to the ICS were administered to define nocturia and other lower urinary tract symptoms. Other physical, reproductive, and health characteristics were also recorded concurrently. Results Overall, 1,636 women were included in the final analyses. The women had an average age of 34.4±5.26 years. The overall prevalence of nocturia was 34.7% (567 of 1,636 women). Women with nocturia were older (p<0.001), had a higher body mass index (p=0.026), and had more children (p<0.001). Nocturia occurred more frequently in women with a history of nocturnal enuresis (p<0.001). Three or more pregnancies, 3 or more deliveries, and age >40 years were significant risk factors for nocturia. We also found that other lower urinary tract symptoms correlated significantly (p<0.001) with nocturia. Conclusions Although the prevalence of nocturia is higher with increasing age, younger adults are also affected. Nocturia may cause sleep disorders, mood disturbances, reduced quality of life, and distractibility. Thus, even if one void nightly causes a patient to experience bother, nocturia should be queried about and should be treated if necessary according to the cause of the disease. PMID:24955226

Efficacy of sorafenib in advanced differentiated and medullary thyroid cancer: experience in a Turkish population  

PubMed Central

Background Antivascular endothelial growth factor tyrosine kinase inhibitors have been used recently in the treatment of advanced differentiated thyroid cancer (DTC) and medullary thyroid cancer (MTC). Off-label sorafenib is used in Turkey with special permission by the Ministry of Health for this indication. Patients and methods Patients with advanced DTC and MTC were retrospectively identified from the Turkish Ministry of Health database. Data on these patients were prospectively collected before permission is granted to use sorafenib. Results Thirty patients with complete data were analyzed: 14 DTC (papillary number [n] =10; follicular n=4) and 16 MTC. The median age of the patients was 57 years (range: 28–79 years), and there were 18 males and 12 females. All DTC patients were iodine refractory and had received a median three doses of radioactive iodine (range: 1–7 doses). Sorafenib was used for a median of 12 months (range: 1–49 months). The overall response rate was 20%, all partial responses, with no complete response. The overall response rate was 14% in DTC and 25% in MTC patients. The median progression-free survival (PFS) was 17.1 months (95% confidence interval [CI]: 7.3–26.8) and overall survival (OS) was not reached. The 2-year PFS and OS were 39% and 68%, respectively. DTC and MTC patients had similar survival outcomes: median PFS of 21.3 months (95% CI: 5.8–36.7) versus 14.5 months (95% CI: 3.7–25.2), respectively (P=0.36), with the median OS not reached in either group (P=0.17). Tumor marker levels did not have any prognostic or predictive role. The toxicity profile was similar to that of other sorafenib trials. Conclusion Sorafenib is an effective and well-tolerated treatment in advanced thyroid cancers. PMID:25548522

Identifying potential predictors of pain–related disability in Turkish patients with chronic temporomandibular disorder pain  

PubMed Central

Background The aims of this study were to examine whether patients’ psychosocial profiles influence the location of pain, and to identify the clinical and psychosocial predictors of high levels of pain-related disability in temporomandibular disorders (TMD) patients with chronic pain at least 6?months in duration. Methods The Research Diagnostic Criteria of TMD (RDC/TMD) data for Axis I and II were obtained for 104 consecutive patients seeking treatment. Data were analyzed using descriptive statistics, t-test, Mann–Whitney U-test, chi-square test, One-way ANOVA, Kruskal-Wallis test, and binary multiple logistic regression tests. Patients were classified into two groups according to Graded Chronic Pain Scale scores: Grade III and IV were scored for patients with high levels of pain-related disability, whereas Grade I and II were scored for patients with low disability. Results Muscle and joint pain were found in 64.9% and 31.8% of the patients, respectively, and 27.3% of the patients suffered from both muscle and joint pain. Psychosocial disability was found in 26% of patients. There were no statistically significant differences among the diagnostic subgroups with regards to the demographic, behavioral, psychological, and psychosocial characteristics. Patients with high levels of pain-related disability had significantly higher depression, somatization, pain intensity and jaw disability scores than those with low levels of pain-related disability. Patients with high levels of pain-related disability were more likely to have higher pain intensity, to report higher somatization symptoms and functional impairment, and were less likely to have joint pain than those with low levels of pain related disability. Conclusion In conclusion, the Turkish version RDC/TMD, based on a dual axis system, may be used to screen chronic TMD patients at high-risk for pain-related disability who need comprehensive care treatment program.

Breast cancer risk perceptions of Turkish women attending primary care: a cross-sectional study.  

PubMed

BackgroundAs the risks and benefits of early detection and primary prevention strategies for breast cancer are beginning to be quantified, the risk perception of women has become increasingly important as may affect their screening behaviors. This study evaluated the women¿s breast cancer risk perception and their accuracy, and determined the factors that can affect their risk perception accuracy.MethodsData was collected in a cross-sectional survey design. Questionnaire, including breast cancer risk factors, risk perceptions and screening behaviors, answered by 624 women visiting primary health care center (PHCC). ¿Perceived risk¿ investigated with numeric and verbal measures. Accuracy of risk perception was determined by women¿s Gail 5-year risk scores.ResultsThe mean age of the participants was 59.62¿±¿1.97 years. Of the women 6.7% had a first-degree relative with breast cancer, 68.9% performed breast self-examination and 62.3% had a mammography, and 82.9% expressed their breast cancer worry as ¿low¿. The numeric measure correlated better with worry and Gail scores. Of the women 65.5% perceived their breast cancer risk accurately. Among the women in ¿high risk¿ group 65.7% underestimated, while in ¿average risk¿ group 25.4% overestimated their risk.ConclusionsTurkish women visiting PHCC are overtly and overly optimistic. This was especially obvious with the result that nearly one third had had no mammography. There is a need for further studies to understand why and how this optimism is maintained so that better screening strategies can be applied at PHCC. All health workers working at PHCC have to be aware of this optimism to prevent missed opportunities for cancer screening. PMID:25476701

Use of Complementary and Alternative Medicine: A survey in Turkish Gastroenterology Patients  

PubMed Central

Background The study examined complementary and alternative medicine (CAM) usage by patients attending a Turkish gastroenterology outpatient clinic. Methods The survey was conducted on 216 patients presenting with gastrointestinal problems during their first visit to the clinic using a 31 item, self-report questionnaire between May and October 2005. Data included information on patient demographics and their gastrointestinal symptoms, as well as items to identify CAM use and patient satisfaction with these therapies. Results Seventy-nine patients (36.6%) reported using one or more forms of CAM. The most commonly used therapy was herbal therapy, usually taken as a tea or infusion. These were used by 27 people (29%) in this subgroup. Common indicators for their use were epigastric pain, constipation, bloating and dyspepsia or indigestion. CAM use among upper GI patients was marginally higher than lower GI patients (41.8% versus 41.2%), but the highest usage was amongst patients with liver disease where 53.8% reported using one or more CAM therapy. About half of the patients learned about CAM from their relatives or friends, with more women than men using the therapies (p < 0.05). Clinical characteristics such as diagnosis, duration of symptoms and prior surgical intervention did not differ between users and non-users of CAM therapies. Multivariate analysis showed that being female and higher educational status were positively associated with CAM usage (p < 0.05). Conclusion CAM usage in our sample of gastrointestinal patients was lower than that described in other countries and other chronic disease groups. This could be due to their low perceived efficacy, or the relatively transient duration of symptoms experienced by the sample. Healthcare professionals need however, to be aware of CAM usage in order to educate patients appropriately about possible adverse effects or drug-interactions. PMID:19857249

Prevalence of obsessive-compulsive disorder in Turkish university students and assessment of associated factors  

PubMed Central

Background Many students who begin university at risky periods for OCD development cannot meet the new challenges successfully. They often seek help and apply to the university health center for psychiatric distress. We aimed to determine the prevalence and associated factors of Obsessive Compulsive Disorder (OCD) at students of the Cukurova University in this cross sectional study. Methods This study was performed in the Cukurova University Faculty of Education with a population of 5500 students; the representative sample size for detecting the OCD prevalence was calculated to be 800. After collecting sociodemographic data, we questioned the students for associated factors of OCD. The General Health Questionnaire-12 (GHQ-12) and Composite International Diagnostic Interview (CIDI, Section K) were used for psychiatric evaluation. Logistic regression analysis was performed to evaluate the linkage between OCD and associated factors. Results A total of 804 university students were included in this study. The GHQ-12-positive students (241 students, 29.9%) were interviewed using Section K of the CIDI (222 students, 27.6%). OCD was diagnosed in 33 (4.2%) students. The Logistic regression analysis of the data showed significant associations between OCD and male gender (p:0.036), living on government dormitory (p: 0.003), living on students' house/parental house (p:0.006), having private room in the parental house (p:0.055) and verbal abuse in the family (p:0.006). Conclusion This study demonstrates a higher prevalence of OCD among a group of university students compared to other prevalence studies of OCD in Turkish society. Furthermore, our findings also suggest relationships between OCD and sociodemographic factors, as well as other environmental stress factors. PMID:19580658

Human Papillomavirus Vaccines and Cervical Cancer: Awareness, Knowledge, and Risk Perception Among Turkish Undergraduate Students.  

PubMed

The aim of this study was to evaluate awareness, knowledge, and risk perception about human papillomavirus (HPV), cervical cancer, and HPV vaccines among undergraduate students in Turkey. The convenience sample of this descriptive cross-sectional study consisted of 605 undergraduate students in Istanbul University during a semester. Demographic characteristics of students, their reproductive health and lifestyle behaviors, and knowledge of HPV and HPV vaccine were questioned using self-administered forms. The overall proportion of students who had heard about HPV infection was 48.8 %, while the proportion of students who had heard of the HPV vaccine was 44.5 %. Forty eight percent of females and 60 % of males reported never having heard of the HPV. Only 45.7 % of females had knowledge about HPV as a cause of genital warts, and 58.1 % correctly indicated that HPV caused cervical cancer. The majority of students in both genders (>80 %) knew that the infection is primarily transmitted through sexual intercourse. Females were more concerned than males about having cervical/penile cancer associated with HPV in the future. Only 46.4 % of females and 39 % of males reported having heard of the HPV vaccine. The majority of the female and male students did not know who should get the HPV vaccine and when to get vaccinated. Among males, 25.8 % reported that they would consider getting vaccinated (if available) and 38.4 % intended to vaccinate their children. Turkish undergraduate students had a low to moderate level of knowledge regarding HPV infection and HPV vaccine. In order to increase awareness about HPV and develop positive behaviors, young people should be provided with accurate information through educational activities in the community and health care services.

Personality, posttraumatic stress and trauma type: factors contributing to posttraumatic growth and its domains in a Turkish community sample  

PubMed Central

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. Method 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. PMID:22893832

Survey of Hfe Gene C282Y Mutation in Turkish Beta-Thalassemia Patients and Healthy Population: A Preliminary Study.  

PubMed

Objective: This study was planned in order to determine the effect of C282Y mutation in development of secondary hemochromatosis in beta-thalassemia patients and to determine the prevalence and allele frequency of this mutation in a healthy control group. Materials and Methods: Eighty-seven children and young adults (46 males and 41 females; mean age: 15.6±6.1 years, range: 3-30 years) with beta-thalassemia major (BTM) and 13 beta-thalassemia intermedia (BTI) patients (6 males and 7 females; mean age: 19.6±3.5 years, range: 13-26 years) were included in the study. The control group comprised 100 healthy blood donors. Results: Neither heterozygous nor homozygous HFE gene C282Y mutation was detected in patients with BTM or BTI, or in control group. Conclusion: The C282Y mutation, which is supposed to be responsible for the majority of hereditary hemochromatosis, was not found to have a role in the development of hemochromatosis in beta-thalassemia patients and was not detected in a healthy Turkish population. However, research on larger cohorts of individuals is required in order to determine the exact prevalence of the HFE gene mutation in Turkish populations from diverse ethnic origins and whether it would have an impact on iron loading in thalassemic populations.

Use of complementary and alternative medicines by a sample of Turkish women for infertility enhancement: a descriptive study  

PubMed Central

Background Infertility patients are a vulnerable group that often seeks a non-medical solution for their failure to conceive. World-wide, women use CAM for productive health, but only a limited number of studies report on CAM use to enhance fertility. Little is known about traditional and religious forms of therapies that are used in relation to conventional medicine in Turkey. We investigated the prevalence and types of complementary and alternative medicine (CAM) used by infertile Turkish women for fertility enhancement. Methods A face-to-face questionnaire inquiring demographic information and types of CAM used for fertility enhancement were completed by hundred infertility patients admitted to a primary care family planning centre in Van, Turkey between January and July 2009. Results The vast majority of infertile women had used CAM at least once for infertility. CAM use included religious interventions, herbal products and recommendations of traditional "hodja's" (faith healers). Of these women, 87.8% were abused in the last 12 months, 36.6% felt not being supported by her partner and 80.5% had never spoken with a physician about CAM. Conclusions Infertile Turkish women use complementary medicine frequently for fertility enhancement and are in need of information about CAM. Religious and traditional therapies are used as an adjunct to, rather than a substitute for, conventional medical therapy. Physicians need to approach fertility patients with sensitivity and should be able to council their patients about CAM accordingly. PMID:20307291

Survey of sulfites in wine and various Turkish food and food products intended for export, 2007-2010.  

PubMed

Surveys were carried out between 2007 and 2010 to determine the total levels of sulfites in 1245 samples of wines, dried apricots, dried vegetables, nuts, juices and purees, frozen foods and cereals containing dried fruit supplied by food inspectors and by food producers for testing or for export certification. Sulfite analysis of wine was carried out using the Ripper method with an LOQ of 5 mg l(-1) and for dried and other foods the Monier-Williams distillation procedure was employed with an LOQ of 10 mg kg(-1). In the survey all wines contained measurable sulfites, but with the exception of one sample of white wine they were otherwise below Turkish Food Codex limits of 160 mg kg(-1) for red wine, 210 mg kg(-1) to white wine and 235 mg kg(-1) for sparkling wine. None of the cereal products, frozen foods, juices or purees contained sulfites above 10 mg kg(-1). However, all dried apricot samples contained significant levels of sulfite with around 40% having levels exceeding the Turkish limit of 2000 mg kg(-1). Significant levels of sulfite were found in other samples of dried fruit with even a fruit and nut bar containing 1395 mg kg(-1) of sulfite, suggesting the dried fruit ingredients contained levels above regulatory limits.

Role of KIR genes and genotypes in susceptibility to or protection against hepatitis B virus infection in a Turkish cohort  

PubMed Central

Background Killer cell immunoglobulin-like receptors (KIRs) are a family of inhibitory and activating receptors expressed by natural killer (NK) cells and regulate NK cell activity in the innate response against viral infections. The aim of this study was to determine the possibility of KIR genes and genotypes as a candidate for susceptibility to or protection against chronic hepatitis B virus (HBV) infection or spontaneous remission of the infection in a Turkish cohort. Material/Methods The present study was carried out on 37 patients with chronic HBV infection, 36 patients in spontaneous remission of HBV infection, and 85 healthy subjects. Sequence-specific oligonucleotide probes analysis was used to investigate 16 KIR genes. All data were statistically analyzed by the Fisher exact test. Results The rate of inhibitory KIR2DL3 (p=0.0) and 3DS1 (p=0.0) were higher in the healthy group than the group composed of chronic HBV patients and patients with spontaneous remission. There were no statistically significant differences between the rate of AA and Bx genotypes of chronic HBV patients and patients with spontaneous remission and the control group (p>0.05). Conclusions Our results suggest that KIR2DL3 and KIR3DS1 genes could be protector genes for HBV infection and they could be important immuno-genetic markers in determining antiviral immunity in the Turkish population.

Cultural context, obsessive-compulsive disorder symptoms, and cognitions: a preliminary study of three Turkish samples living in different countries.  

PubMed

Previous research findings have suggested that recent cognitive accounts of obsessive-compulsive disorder (OCD) are valid across different cultural contexts for both clinical and nonclinical samples; however, there is evidence that cultural differences may have an impact on a number of cognitive variables. For this reason, immigration provides an exceptional opportunity for an examination of the role of cultural context in cognitions and possible changes in cultural characteristics. To this end, the present study examined the interrelationships between thought-action fusion, thought control strategies and OCD symptoms in three nonclinical samples, taking the immigration factor into consideration. Thus, the current study included three Turkish sample groups: those who remigrated to Turkey from Bulgaria, those still living in Bulgaria, and those that have always resided in Turkey. The findings of the study supported the role of thought and action fusion and control strategies in OCD symptoms in a cross-cultural context. To illustrate, worry, as a thought control strategy for OCD symptoms, was a common factor in all three sample groups. However, differences were also noted between the groups, despite having the same ethnic origin. Although they immigrated back to Turkey and have been living there for a considerable period of time, the Turkish remigrants retained similar characteristics to the respondents in Bulgaria on cognitions in general. Consequently, it may be suggested that cultural context might have a relative impact on certain correlates. A replication of these findings using different immigration groups and examining various cultural factors is strongly encouraged. PMID:22044185

Biodiversity of yeast mycobiota in "sucuk," a traditional Turkish fermented dry sausage: phenotypic and genotypic identification, functional and technological properties.  

PubMed

In this study, yeasts from Turkish fermented sucuks were identified and their functional and technological properties were evaluated. Two hundred fifty-five yeast isolates were obtained from 35 different sucuk samples from different regions of Turkey. The yeast isolates were determined as genotypic using 2 different polymerase chain reaction (PCR) methods (rep-PCR and RAPD-PCR). Functional and technological properties of including proteolytic, lipolytic, and catalase activities, tolerance to NaCl and bile, as well as growing rates at different temperature and pH conditions selected yeast strains were also evaluated. Candida zeylanoides and Debaryomyces hansenii were dominant strains in sucuk samples. All C. zeylanoides and D. hansenii tested could grow at the condition of 15% NaCl and 0.3% bile salt. However, none of the strains were able to grow at 37 °C, even though catalase activity, weak proteolytic and lipolytic activities was still observed. D. hansenii were able to grow only at pH 3, while some of C. zeylanoides could grow at lower pH levels (pH 2). Three and 4 strains of C. zeylanoides showed ?-hemolysis activity and nitrate reduction ability to nitrite, respectively. D. hansenii did not have properties, which are ?-hemolysis, nitrate reduction, or hydrogen sulfide production. Overall, diverse yeast mycobiota present in Turkish fermented sucuk and their functional and technological properties were revealed with this study. PMID:25273925

The Effects of Heat Treatment on the Physical Properties and Surface Roughness of Turkish Hazel (Corylus colurna L.) Wood  

PubMed Central

Heat treatment is often used to improve the dimensional stability of wood. In this study, the effects of heat treatment on the physical properties and surface roughness of Turkish Hazel (Corylus colurna L.) wood were examined. Samples obtained from Kastamonu Forest Enterprises, Turkey, were subjected to heat treatment at varying temperatures and for different durations. The physical properties of heat-treated and control samples were tested, and oven-dry density, air-dry density, and swelling properties were determined. A stylus method was employed to evaluate the surface characteristics of the samples. Roughness measurements, using the stylus method, were made in the direction perpendicular to the fiber. Four main roughness parameters, mean arithmetic deviation of profile (Ra), mean peak-to-valley height (Rz), root mean square roughness (Rq), and maximum roughness (Ry) obtained from the surface of wood were used to evaluate the effect of heat treatment on the surface characteristics of the specimens. Significant difference was determined (p = 0.05) between physical properties and surface roughness parameters (Ra,Rz, Ry, Rq) for three temperatures and three durations of heat treatment. The results showed that the values of density, swelling and surface roughness decreased with increasing temperature treatment and treatment times. Turkish Hazel wood could be utilized successfully by applying proper heat treatment techniques without any losses in investigated parameters. This is vital in areas, such as window frames, where working stability and surface smoothness are important factors. PMID:19325831

ABCB1 C3435T and CYP2C19*2 polymorphisms in a Palestinian and Turkish population: A pharmacogenetic perspective to clopidogrel  

PubMed Central

Clopidogrel is an antiplatelet drug used to prevent recurrent ischemic events after acute coronary syndrome and/or coronary stent implantation. Single nucleotide polymorphisms (SNPs) such as CYP2C19*2 and ABCB1 C3435T have been found to play a role in different individual responses to clopidogrel. Since the prevalence of these SNPs is generally known to differ from one population to another, the aim of this study was to examine their prevalence in both a Palestinian and Turkish population. One hundred unrelated Palestinian subjects and 100 unrelated Turkish subjects were analyzed for CYP2C19*2 and ABCB1 C3435T polymorphisms by the amplification refractory mutation system (ARMS). Results showed an ABCB1 3435 T allele frequency of 0.46 (95% CI 0.391 to 0.529) in the Palestinian sample and 0.535 (95% CI 0.4664 to 0.6036) in the Turkish sample. CYP2C19*2 allele frequency was 0.095 (95% CI 0.0558 to 0.134) in the Palestinian sample and 0.135 (95% CI 0.088 to 0.182) in the Turkish sample. Our results provide information about the prevalence of the polymorphisms related to clopidogrel response in both the Palestinian and Turkish populations, in order to improve the safety and efficacy of clopidogrel through use of genetically guided, individualized treatment. The prevalence of these clinically significant alleles shed light on the importance of testing them before prescribing clopidogrel. PMID:25606414

Turkish health system reform from the people’s perspective: a cross sectional study  

PubMed Central

Background Since 2003, Turkey has implemented major health care reforms to develop easily accessible, high-quality, efficient, and effective healthcare services for the population. The purpose of this study was to bring out opinions of the Turkish people on health system reform process, focusing on several aspects of health system and assessing whether the public prefer the current health system or that provided a decade ago. Methods A cross sectional survey study was carried out in Turkey to collect data on people’s opinions on the healthcare reforms. Data was collected via self administered household’s structured questionnaire. A five-point Likert-type scale was used to score the closed comparative statements. Each statement had response categories ranging from (1) “strongly agree” to (5) “strongly disagree.” A total of 482 heads of households (response rate: 71.7%) with the mean age of (46.60 years) were selected using a multi stage sampling technique from seven geographical regions in Turkey from October 2011 to January 2012. Multiple logistic regressions were performed to identify significant contributing factors in this study. Results Employing descriptive statistics it is observed that among the respondents, more than two third of the population believes that the changes have had positive effects on the health system. A vast majority of respondents (82.0%) believed that there was an increase in accessibility, 73.7% thought more availability of health resources, 72.6% alleged improved quality of care, and 72.6% believed better attitude of politician/mass media due to the changes in the last 10 years. Indeed, the majority of respondents (77.6%) prefer the current health care system than the past. In multivariate analysis, there was a statistically significant relationship between characteristics and opinions of the respondents. The elderly, married females, perceived themselves healthy and those who believe that people are happier now than 10 years ago have a more positive opinion of the changes. While, the single unemployed from rural region who perceived themselves as unhealthy and believe that people are unhappy now compare to ten years ago showed less positive opinions. Conclusions Hence, we conclude that from the people’s perspective overall the health system reforms were most likely successful. PMID:24447374

The Burden of JAK2V617F Mutated Allele in Turkish Patients With Myeloproliferative Neoplasms  

PubMed Central

Background Studies regarding the impact of JAK2V617F allele burden on phenotypic properties and clinical course in Philadelphia-negative myeloproliferative neoplasms (Ph-negative MPNs) have reported variable results. We aimed to analyze the association of mutated JAK2V617F allele burden with laboratory characteristics and clinical phenotype in Turkish patients (107 essential thrombocythemia (ET) and 77 primary myelofibrosis (PMF)). Methods Peripheral blood samples of 184 patients with Ph-negative MPNs were analyzed for JAK2V617F allele status and burden. JAK2 MutaScreen assay (Ipsogen, Luminy Biotech, Marseille, France) was used to detect the JAK2V617F status and quantitative JAK2V617F allele burdens in genomic DNA using TaqMan allelic discrimination. Results Frequency of JAK2V617F-positive patients with high mutation load (allele burden > 50%) was higher in PMF compared to ET (23.4% and 4.7%, respectively; P = 0.001). We found significant association between ET patients with high JAK2V617F allele burden and lower hemoglobin (Hgb) and hematocrit (Hct), higher LDH levels and more prevalent massive splenomegaly (P = 0.001, P = 0.001, P = 0.012 and P = 0.015, respectively). ET patients with high mutation load displayed higher prevalence of bleeding compared to low mutation load and wild-type mutational status (P = 0.003). Rate of DVT was significantly higher in ET patients with mutant allele burden in upper half compared to lower half and wild-type (P = 0.029). We observed significant association between PMF patients with high JAK2V617F allele burden and higher Hgb, Hct levels and leukocyte counts (P = 0.003, P = 0.021 and P = 0.001, respectively). Conclusions Our study demonstrated JAK2V617F allele burden correlates with clinical features in ET and PMF. We conclude quantification of JAK2V617F mutation contributes to the workup of Ph-negative MPNs. PMID:25584101

Turkish Cloud-Radiation Database (CRD) and Its Application with CDR Bayesian Probability Algorithm  

NASA Astrophysics Data System (ADS)

ABSTRACT It is rather a very difficult task to determine ground rainfall amounts from few Special Sensor Microwave Imager/Sounder (SSMI/S) channels. Although ground rainfall cannot be observed from the space directly, but knowledge about the cloud physics helps to estimate the amound of ground rainfall. SSMI/S includes so much information about the atmospheric structure, however it cannot provide cloud micro-physical structural information. In such a situation, in the rainfall algorithm, besides the SSMI/S data, it is necessary to incorporate cloud micro-physical properties from an external data source. These properties can be obtained quite simply by the help of Cloud Resolving Model (CRM). Later, in addition to all available data, also micro-physical properties obtained from Radiative Transfer Model (RTM) help to determine the SSMI/S brightness temperatures (Brightness temperatures - TBs), which can then be correlated with Cloud-Radiation Database (CRD) data generation. SSMI/S satellite data and CDR provide a common basis for rainfall prediction procedure through CDR Bayesian probability algorithm, which combines the two sets of data in a scientific manner. The first applications of this algorithm, which is being used up today, is due to various researchers. In this work, in order to establish a reflection of available data processing CDR CRM University of Wisconsin - Non-hydrostatic Modeling System (UW-NMS) model is employed, which is first developed by Prof. Gregory J. Tripoli. It is also used by Turkish Meteorological Service by benefiting from radar network data, and finally 14 simulations are realized in this study. Moreover, one case study is fulfilled by using a 3X3 spatial filtering, and then radar data and result of CDR Bayesian probability algorithm are compared with each other. On 9 September 2009 at 03:40 GMT rainfall event on comparatively flat area matches far better with the retrieval values and hence the spatial rainfall occurrence extent and numerical values are very close to each other.Statistical features (9 September 2009 at 03:40 GMT) Rainfall occurrence indices (9 September 2009 at 03:40 GMT)

Recent advancements on modelling the exchange flow dynamics through the Turkish Strait System  

NASA Astrophysics Data System (ADS)

The system composed by the two narrow Straits, Dardanelles and Bosphorus, and the Marmara Sea is known as the Turkish Straits System (TSS). The scientific questions on the role of the TSS in coupling the adjacent basins of the Mediterranean and Black Seas with highly contrasting properties, in a region of high climatic variability and materials transport depending critically on the cycle of water can only be answered by model predictions of the processes that determine the integral properties of the coupled sub-systems. This can only be achieved if the entire TSS is modeled as a finely resolved integral system that appropriately accounts for the high contrasts in seawater properties, steep topography, hydraulic controls, fine and meso-scale turbulence, nonlinear and non-hydrostatic effects, thermodynamic states and an active free-surface in the fullest extent, based on well represented fluid dynamical principles. In this study the MITgcm is used at very high resolution to study this extreme environment that needs to be represented as a whole and with the full details of its highly contrasting properties. The model domain chosen extends over the entire TSS, including also part of the north-east Aegean Sea at south, and the Black Sea at north of the domain. A non-uniform curvilinear orthogonal grid covers the domain at variable resolution: from less than 50 m in the two Straits up to about 1 Km in the Marmara Sea. To adequately resolve the complex hydraulic dynamics of the TSS, the model grid is made by 100 vertical z-levels. The model is initialized with three different water masses filling the western part of the domain, the Marmara Sea and the eastern side of the domain respectively, with vertical profiles selected from CTD casts obtained during the cruise of the R/V B?L?M of the Institute of Marine Sciences in June-July 2013. With the initial condition specified as lock-exchanges at the two straits, the model is left free to adjust to the expected two-way exchange. The capability of MITgcm to represent the two-layer exchange dynamics both in the straits and in the Marmara Sea is examined. The non-uniform curvilinear orthogonal grid and the vertical resolution implemented have demonstrated to be sufficient to capture the fine scales within the two Straits and also to well represent mesoscale in the Marmara Sea. The response of the currents and density structure over the water column to different net flow is also examined through the setup of experiments with varying net barotropic volume fluxes. The numerical experiments have been realized thanks to the PRACE (Partnership for Advanced Computing in Eureope) infrastructure.

Comparison of milk yield and animal health in Turkish farms with differing stall types and resting surfaces.  

PubMed

The current study was carried out to determine the influence of different resting surfaces and stall types on milk yield and animal health. Study was carried out in Bursa that is one of the most important cities of Turkey in terms of dairy production. Effects of resting surfaces and stall types on milk yield were found to be important. Also influence of different resting surfaces and stall types on lactation length was examined and found that rubber mats were different from the two other options. Relationships between different resting surfaces or stall types and health problems were examined and connection between stall type and repeat breeding (RB), dystocia, retained placenta and a connection between resting surface types and RB and clinical mastitis were found to be important. Considering their economic reflections, it can be said that results are quite important to the Turkish dairy industry. PMID:25557824

Clinical, radiographic, diagnostic and cephalometric features of pycnodysostosis in comparison with Turkish cephalometric norms: A case report  

PubMed Central

Pycnodysostosis is a rare genetic disorder and was first described in 1962 by Maroteaux and Lamy. The incidence of this anomaly is estimated to be 1.7 per 1 million births. The principal characteristics of this disorder are short stature, prominent eyes with blue sclera, beaked nose, cranial dysplasia, exposed fontanelles and cranial sutures, clavicular dysplasia, total/partial dysplasia of the terminal phalanges, obtused mandibular gonial angle, and generally increased bone density. Some features of pycnodysostosis are similar to osteopetrosis and cleidocranial dysostosis. Therefore, it must be distinguished from osteopetrosis and cleidocranial dysostosis in order to diagnose it in individuals of a younger age. The aims of this case report were to show the clinical, radiographic, and diagnostic features, as well as the cephalometric characteristics of pycnodysostosis in comparison with Turkish cephalometric norms.

Ethanolic and aqueous extracts obtained from nine plant species from seven families selected depending on their use in Turkish folk medicine, including Citrillus lanatus (Thunb.) Matsum. (seed), Jasminum fruticans L. (branches), Juniperus drupacea Labill. (fruits), Juniperus nana L. (fruit and leaves), Juniperus oxcycedrus L (fruit and leaves), Mentha longifolia L. (herba), Pinus nigra ssp. pallasiana (Lamb.) Richt. (fruits), Plantago lanceolata L. (leaves), and Zea mays L. (seed) were evaluated for their in vivo anthelmintic activity. Among the plant extracts studied, both ethanolic and aqueous extracts of Jasminum fruticans, Mentha longifolia and Pinus nigra ssp. pallasiana, the aqueous extracts of Zea mays, the ethanolic extracts of Citrillus lanatus, Juniperus drupacea (fruit), Juniperus oxcycedrus and Plantago lanceolata displayed significant anthelmintic activity against pinworms, Syphacia obvelata and Aspiculuris tetraptera, in mice. Rest of the extracts from plants did not show any remarkable anthelmintic activity. The results were considered significant at p<0.05. PMID:16790330

A novel mutation of ABCG5 gene in a Turkish boy with phytosterolemia presenting with macrotrombocytopenia and stomatocytosis.  

PubMed

Phytosterolemia is a rare autosomal recessive sterol storage disease caused by mutations in ABCG5 and ABCG8 genes. A 9-year-old Turkish boy who was presented with exclusively hematologic abnormalities had elevated plant sterol levels. Sequencing of ABCG5 and ABCG8 genes revealed a novel homozygous IVS10-1 G>T mutation in ABCG5 gene. Four of the 13 family members had xanthoma but they had neither hematologic abnormalities nor IVS10-1 G>T mutation. Ezetimibe therapy reduced plant sterol levels in association with marked clinical improvement. Plant sterol levels and ABCG5/ABCG8 genes should be analysed in patients with unexplained hemolytic anemia and macrothrombocytopenia. PMID:24623560

An investigation of some Turkish herbal medicines in Salmonella typhimurium and in the COMET assay in human lymphocytes.  

PubMed

Medicinal plants play a major role in the life of Turkish people and of late medicinal plant usage has increased in many countries. Green plants in general contain mutagenic and carcinogenic substances, but there is little information about the biological activities of herbal medicine. In the present study, therefore, various Turkish medicinal herbs were investigated for their genotoxic potential in the Salmonella typhimurium microsomal activation assay and the alkaline single cell gel electrophoresis (COMET) assay. Extracts from these medicinal herbs and some fractions of these extracts were examined. The species investigated were Arctium minus, Ecballium elatterium, Momordica charantia, Plantago major, Urtica dioica, Viscum album, Salvia triloba, Euphorbia rigida, Stachys lavandulifolia, Acteoside, Abies nordmannia. They are used for various immune disorders and are applied either topically or taken orally as a herbal tea. Of the 19 samples of the extracts and fractions investigated, none produced a positive response in strains TA98 and TA100 with or without metabolic activation, but all produced an increase above negative control values in the COMET assay. Some extracts were investigated further and produced dose-related increases. In the case of Urtica and Euphorbia species, where two fractions from these plants were examined, one fraction produced a greater response than the other. It is suggested that the lesser response of the fractions might be due to less DNA strand-breaking agents in the fractions or they may have antigenotoxic properties. The breaks that are detected in the COMET assay could be alkali-labile AP-sites and intermediates in base- or nucleotide-excision repair and are difficult to interpret in terms of hazard for man. Further studies with additional genotoxicity assays would be required to make such a prediction. PMID:8875742

Germline mutations in the BRCA1 and BRCA2 genes in Turkish breast/ovarian cancer patients.  

PubMed

In this study we genotyped Turkish breast/ovarian cancer patients for BRCA1/BRCA2 mutations: protein truncation test (PTT) for exon 11 BRCA1 of and, multiplex PCR and denaturing gradient gel electrophoresis (DGGE) for BRCA2, complemented by DNA sequencing. In addition, a modified restriction assay was used for analysis of the predominant Jewish mutations: 185delAG, 5382InsC, Tyr978X (BRCA1) and 6174delT (BRCA2). Eighty three breast/ovarian cancer patients were screened: twenty three had a positive family history of breast/ovarian cancer, ten were males with breast cancer at any age, in eighteen the disease was diagnosed under 40 years of age, one patient had ovarian cancer in addition to breast cancer and one patient had ovarian cancer. All the rest (n=30) were considered sporadic breast cancer cases. Overall, 3 pathogenic mutations (3/53-5.7%) were detected, all in high risk individuals (3/23-13%): a novel (2990insA) and a previously described mutation (R1203X) in BRCA1, and a novel mutation (9255delT) in BRCA2. In addition, three missense mutations [two novel (T42S, N2742S) and a previously published one (S384F)] and two neutral polymorphisms (P9P, P2532P) were detected in BRCA2. Notably none of the male breast cancer patients harbored any mutation, and none of the tested individuals carried any of the Jewish mutations. Our findings suggest that there are no predominant mutations within exon 11 of the BRCA1 and in BRCA2 gene in Turkish high risk families. PMID:12655560

The structure of the crust in the Turkish-Iranian Plateau and Zagros using Lg Q and velocity  

NASA Astrophysics Data System (ADS)

We present a new approach for understanding the origin and nature of seismic anomalies in the continental crust of the Northern Middle East. We have created detailed attenuation (QLg) and velocity (VLg) models for the Northern Middle East based on the analysis of waveforms of regional seismic phase Lg from 3171 regional earthquakes recorded at 578 stations in Turkish and Iranian Plateaus and surrounding regions. The attenuation and velocity models are assumed to serve as proxies for the bulk average crustal shear wave attenuation (Q?) and velocities (Vs). 31 232 reliable Lg spectra were collected and used to measure the two-station method (TSM) and reverse two-station/event method (RTM) Lg Q at 1 Hz (Q0) and its frequency-dependence factor (?). The Lg Q0 and ? values are measured over the individual TSM and RTM paths and are then used to perform an LSQR tomographic inversion for lateral variations in Q0 and ?. The Lg Q0 and ? models both correlate well with the major tectonic boundaries in the region. The tomographic models as well as the individual TSM and RTM measurements show lower values of Lg Q0 over the Turkish-Anatolian Plateau (<150) than those observed over the Iranian Plateau (150-400). Furthermore, we obtained the Lg group velocity model by inverting the time of the first arrival of the Lg waveform on each seismogram. Our Q measurements are strongly correlated with the measurements of Lg group velocity (VLg) suggesting that the source of many of the low Q and velocity anomalies is likely the same. The regions where we see negative correlations are likely a result of Sn to Lg converted energy. Our results also have implications for the far field ground motions, suggesting that large earthquakes in eastern Iran could have a significant far field ground motions due to relatively low crustal attenuation within the Iranian plateau.

A cone-beam computed tomography study of the root canal morphology of anterior teeth in a Turkish population  

PubMed Central

Objective: The aim of this study was to determine the root and canal morphology of the maxillary and mandibular anterior teeth in a Turkish population by analyzing cone-beam computed tomography (CBCT) images. Materials and Methods: CBCT images of 417 females and 410 males with a mean age of ranging from 14 to 70 years were examined in this study. A total of 1453 maxillary central incisors, 1504 maxillary lateral incisors, 1523 maxillary canines, 1582 mandibular central incisors, 1603 mandibular lateral incisors, and 1604 mandibular canines were analyzed. The number of root canals and the canal configurations were investigated and then were classified according to Vertucci's classification. The data were analyzed with the Pearson Chi-square test. Results: The Type 1 canal configuration was most prevalent in the maxillary anterior teeth (96.8-99.7%). The Types 2, 3, 4, and 5 canal configurations were observed within the range of 0-1.3%, 0-0.8%, 0-0.7%, and 0-1.8%, respectively. In the mandibular anterior teeth, the Type 1 canal configuration was most prevalent (77-95%). The Types 2, 3, 4, and 5 canal configurations were observed within a range of 0.2-2.7%, 0.2-1.6%, 0.9-5.9%, and 1.8-14.4%, respectively. The prevalence of two canals was higher in males than in females both in the maxillary and mandibular anterior teeth (P < 0.05). Conclusions: Type 1 was the most prevalent canal configuration of maxillary and mandibular anterior teeth in the Turkish population. Type 5 was the most frequently observed canal configuration of the two canalled teeth. The incidence of root canal numbers and configurations differed with sex. PMID:25202207

ATXN2 and Its Neighbouring Gene SH2B3 Are Associated with Increased ALS Risk in the Turkish Population  

PubMed Central

Expansions of the polyglutamine (polyQ) domain (?34) in Ataxin-2 (ATXN2) are the primary cause of spinocerebellar ataxia type 2 (SCA2). Recent studies reported that intermediate-length (27–33) expansions increase the risk of Amyotrophic Lateral Sclerosis (ALS) in 1–4% of cases in diverse populations. This study investigates the Turkish population with respect to ALS risk, genotyping 158 sporadic, 78 familial patients and 420 neurologically healthy controls. We re-assessed the effect of ATXN2 expansions and extended the analysis for the first time to cover the ATXN2 locus with 18 Single Nucleotide Polymorphisms (SNPs) and their haplotypes. In accordance with other studies, our results confirmed that 31–32 polyQ repeats in the ATXN2 gene are associated with risk of developing ALS in 1.7% of the Turkish ALS cohort (p?=?0.0172). Additionally, a significant association of a 136 kb haplotype block across the ATXN2 and SH2B3 genes was found in 19.4% of a subset of our ALS cohort and in 10.1% of the controls (p?=?0.0057, OR: 2.23). ATXN2 and SH2B3 encode proteins that both interact with growth receptor tyrosine kinases. Our novel observations suggest that genotyping of SNPs at this locus may be useful for the study of ALS risk in a high percentage of individuals and that ATXN2 and SH2B3 variants may interact in modulating the disease pathway.

Four Flavours of Orogenic Plateau Magmatism: What's Melting Beneath the Turkish-Iranian Plateau?  

NASA Astrophysics Data System (ADS)

Orogenic plateaux are first order topographic features of the continents, occurring in collision zones such as Tibet and Andean-style continental arcs. Plateaux are sites of abundant mantle-derived magmatism, but there is little understanding of its geodynamic cause in spite of assumptions that slab break-off or lithospheric thinning are controlling factors in melt production. The Turkish-Iranian Plateau formed on the Eurasian Plate after the ~30 Ma Arabia-Eurasia collision. Neogene-recent volcanoes are found up to ~800 km from the suture, and have huge compositional variation. We define four varieties of recent mafic magmatism spatially and geochemically. (1) Close to the Bitlis Suture in Eastern Turkey, slab break-off is likely to have occurred at ~10 Myr, and there is little mantle lithosphere present. Magmatism is mostly calc-alkaline, sourced from the asthenosphere or any remaining mantle lithosphere, and is affected by crustal contamination. (2) In the Lesser Caucasus up to ~500 km from the suture, magmatism is more alkaline, less crustally-contaminated and is derived from subduction-modified lithospheric mantle. (3) Close to the Zagros Suture in Iran, the lithosphere may have thickened to >200 km during collision. Magmatism is volumetrically limited and derived almost exclusively from the lithospheric mantle, with trace element-enriched alkaline or ultrapotassic compositions. Unlike the Lesser Caucasus, there is little magmatism in the Iranian desert up to ~500 km from the suture. (4) Beyond ~500 km from the Bitlis-Zagros Suture Zone, there is sparse, compositionally variable magmatism: it is OIB-like in Eastern Iran, more akin to Zagros magmatism in the Alborz, and more felsic above the ~55 km thick crust of the Greater Caucasus. Geochemical data suggest that magmatism in (1) is caused by asthenospheric upwelling following slab breakoff, whereas in (2) it is dominated by melting of the base of the still-present lithospheric mantle during convective removal. Magmatism in (3) may be triggered by the breakdown of hydrous phases such as amphibole and phlogopite within the lithospheric mantle which release water and lower the mantle solidus. In (4) melting has diverse triggers not clearly related to the Bitlis-Zagros Suture. OIB-like magmas in (4) may form beneath lithospheric thin-spots whilst more arc-like magmas may be due to lithospheric thickening in the Alborz and Greater Caucasus. The spatial distribution of different magma types leads us to conclude that the ~500 km distance from the suture represents a cut-off at which stirring of the asthenosphere due to slab break-off ceases to be an effective propellant for decompression melting and lithospheric delamination. The relative paucity of magmatism beneath and inboard from the Zagros Mountains lends support to the idea that the mantle is not being stirred by break-off processes and that the lithosphere is particularly thick beneath this region. There is no single trigger or source of magmatism beneath the TIP, but two processes may dominate: melting due to heating and dehydration of the lithosphere as it is thickened or convectively removed, and decompression melting of upwelling asthenosphere.

Four flavours of orogenic plateau magmatism: what's melting beneath the Turkish-Iranian Plateau?  

NASA Astrophysics Data System (ADS)

Orogenic plateaux are first order topographic features of the continents, occurring in collision zones such as Tibet and Andean-style continental arcs. Plateaux are sites of abundant mantle-derived magmatism, but there is little understanding of its geodynamic cause in spite of widespread assumptions that slab break-off or lithospheric thinning are controlling factors. Late Cenozoic magmatism is distributed 100s of km from the Arabia-Eurasia suture zone across the modern Turkish-Iranian Plateau (TIP) in the countries of Armenia, Iran, Turkey and adjacent areas. There is huge compositional variation. Here we document four varieties of recent TIP magmas and argue their occurrence is controlled by: geographic location, prior fertilisation of the lithospheric mantle, lithospheric thickness, temperature and stability, and asthenospheric convection. (1) Close to the original Arabia-Eurasia suture in Eastern Turkey, slab break-off is likely to have occurred at ~10 Myr, and the lithosphere is presently thin (45-50 km) with little or no mantle lithosphere present. Magmatism is mostly calk-alkaline, sourced from the asthenosphere or any remaining mantle lithosphere, and is affected by crustal contamination. (2) In the Lesser Caucasus up to ~500 km from the suture, magmatism is more alkaline, less contaminated and is derived from subduction-modified lithospheric mantle. (3) Close to the suture in Iran, the lithosphere has thickened to >200 km during collision. Magmatism is volumetrically limited and derived almost exclusively from the lithospheric mantle, with highly enriched alkaline or ultrapotassic compositions. Unlike the Lesser Caucasus, there is little or no magmatism in the Iranian desert up to 500 km from the suture. (4) Beyond ~500 km from the suture zone, magmatism is sparse and varies in composition: dominantly OIB-like in Eastern Iran, alkaline but arc-like in the Alborz, and more felsic above the relatively thick (~55 km) crust of the Greater Caucasus. Magmatism in (1) is plausibly caused by asthenospheric upwelling following slab breakoff, whereas magmatism in (2) is dominated by melting of the base of the still-present lithospheric mantle during convective removal or asthenospheric upwelling. Magmatism in (3) is probably triggered by decomposition of hydrous phases within the lithosphere, whereas those in (4) have various triggers: OIB-like magmas may relate to local delamination or thin-spots, more arc-like magmas may be due to lithospheric thickening in the Alborz and Greater Caucasus. Geochemical and geodynamic modelling suggest that at ~500 km distance from the suture there is a cut-off, at which asthenosphere stirring (due to slab break-off) ceases to be an effective cause of decompression melting, small-scale lithospheric delamination and convection. The relative scarcity of magmatism in Western and Central Iran is good evidence that the mantle beneath this region is not being stirred by delamination processes: there is otherwise little difference in the previous Tethyan subduction histories of Iran and Eastern Turkey. Overall, there is no single trigger or source of magmatism beneath the TIP, but two processes appear to dominate: melting due to dehydration of the lithosphere as it is thickened or convectively removed, and decompression melting of upwelling asthenosphere.

Lack of Association between PTPN22 Gene +1858 C>T Polymorphism and Susceptibility to Generalized Vitiligo in a Turkish Population  

PubMed Central

Background Vitiligo is an autoimmune polygenic disorder characterized by loss of pigmentation due to melanocyte destruction. The PTPN22 gene +1858 C>T single nucleotide polymorphism (rs2476601) has been shown to be associated with various autoimmune disorders. Objective The aim of this study was to investigate whether the PTPN22 gene +1858 C>T single nucleotide polymorphism is associated with susceptibility to generalized vitiligo in a Turkish population. Methods One hundred and seven patients with generalized vitiligo, and one hundred and twelve gender-, age-, and ethnic-matched controls were enrolled in the study. Genotyping was done by polymerase chain reaction-restriction fragment length polymorphism. Results The PTPN22 +1858 C>T genotype and allele frequencies of the generalized vitiligo patients did not differ significantly from those of healthy controls. Conclusion We found no association between the PTPN22 +1858 C>T gene polymorphism and vitiligo susceptibility in Turkish generalized-vitiligo patients. PMID:24648691

Conversion of Molybdenum-99 production process to low enriched uranium: Neutronic and thermal hydraulic analyses of HEU and LEU target plates for irradiation in Pakistan Research Reactor-1  

NASA Astrophysics Data System (ADS)

Technetium-99m, the daughter product of Molybdenum-99 is the most widely needed radionuclide for diagnostic studies in Pakistan. Molybdenum-99 Production Facility has been established at PINSTECH. Highly enriched uranium (93% 235U) U/Al alloy targets have been irradiated in Pakistan Research Reactor-1 (PARR-1) for the generation of fission Mo-99, while basic dissolution technique is used for separation of Mo-99 from target matrix activity. In line with the international objective of minimizing and eventually eliminating the use of HEU in civil commerce, national and international efforts have been underway to shift the production of medical isotopes from HEU to LEU (LEU; <20% 235U enrichment) targets. To achieve the equivalent amount of 99Mo with LEU targets, approximately 5 times uranium is needed. LEU aluminum uranium dispersion target has been developed, which may replace existing HEU aluminum/uranium alloy targets for production of 99Mo using basic dissolution technique. Neutronic and thermal hydraulic calculations were performed for safe irradiation of targets in the core of PARR-1.

Mal de Meleda is a rare form of palmoplantar keratoderma, and recently mutations in the ARS (component) B gene have been identified in families with this disease. We identified a recurrent nonsense mutation, R96X, in four families of Turkish descent. In this report, we demonstrate that these families share a common ancestral haplotype at the mal de Meleda locus, suggesting a founder effect. PMID:12787122

The severity of Internet addiction risk and its relationship with the severity of borderline personality features, childhood traumas, dissociative experiences, depression and anxiety symptoms among Turkish university students.  

PubMed

The aim of this study was to investigate the relationship of Internet addiction (IA) risk with the severity of borderline personality features, childhood traumas, dissociative experiences, depression and anxiety symptoms among Turkish university students. A total of 271 Turkish university students participated in this study. The students were assessed through the Internet Addiction Scale (IAS), the Borderline Personality Inventory (BPI), the Dissociative Experiences Scale (DES), the Childhood Trauma Questionnaire (CTQ-28), the Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI). The rates of students were 19.9% (n=54) in the high IA risk group, 38.7% (n=105) in the mild IA risk group and 41.3% (n=112) in the group without IA risk. Correlation analyses revealed that the severity of IA risk was related with BPI, DES, emotional abuse, CTQ-28, depression and anxiety scores. Univariate covariance analysis (ANCOVA) indicated that the severity of borderline personality features, emotional abuse, depression and anxiety symptoms were the predictors of IAS score, while gender had no effect on IAS score. Among childhood trauma types, emotional abuse seems to be the main predictor of IA risk severity. Borderline personality features predicted the severity of IA risk together with emotional abuse, depression and anxiety symptoms among Turkish university students. PMID:25023365

Evaluation of the root and canal morphology of mandibular permanent molars in a south-eastern Turkish population using cone-beam computed tomography  

PubMed Central

Objective: The aim of this retrospective study was to determine the root and canal morphology of the mandibular first and second permanent molars in a Turkish population using cone-beam computed tomography (CBCT). Materials and Methods: CBCT images of mandibular first (n = 966) and second molar (n = 1165) teeth from 850 Turkish patients were evaluated. The root canal configurations were classified according to the method of Vertucci. The data were analyzed by Pearson's Chi-square test. Results: The majority of mandibular molars were two rooted with three canals; however, three roots were identified in 0.05% of the first molars and 0.01% of the second molars, and 100% of the additional root canals were of type I configuration. Mesial roots had more complex canal systems with more than one canal, whereas most distal roots had a type I configuration. Conclusions: Within the limitations of this study, it can be concluded that CBCT scanning provides supplemental information about the root canal configurations of mandibular molars in a Turkish population. This study may help clinicians in the root canal treatment of mandibular molars. PMID:24966763

Quality of life in patients with multiple sclerosis and urinary disorders: reliability and validity of Turkish-language version of Incontinence Quality of Life Scale.  

PubMed

Incontinence is one of the most frequently encountered problems in multiple sclerosis (MS), and it has a negative effect on the daily lives of patients. Therefore, it is important to investigate this complaint and start appropriate treatment early. The aim of our study was to demonstrate the validity and reliability of the Turkish-language Incontinence Quality of Life Scale (I-QOL) in patients with MS. We included 37 patients with MS in this study. For analysis of test-retest reliability, we administered the Turkish-language version of I-QOL developed by a "translation-back translation" method to patients on the day of admission and 1 week after admission. To assess validity, we also evaluated patients with the Multiple Sclerosis Quality of Life Scale (MQOL-54) and Expanded Disability Status Scale (EDSS). We calculated the intraclass correlation coefficient of the I-QOL (total and all subscores) as 0.88 to 0.91 and the Cronbach alpha score as 0.88 to 0.91 (p < 0.05). We found a significant correlation among all subscores of I-QOL and physical and mental subscores of MQOL-54 and EDSS (p < 0.05). Our study has demonstrated the internal consistency and reliability of the I-QOL in the Turkish language in patients with MS. PMID:20437328

A Walk through TRIDEC's intermediate Tsunami Early Warning System for the Turkish and Portuguese NEAMWave12 exercise tsunami scenarios  

NASA Astrophysics Data System (ADS)

On November 27-28, 2012, the Kandilli Observatory and Earthquake Research Institute (KOERI) and the Portuguese Institute for the Sea and Atmosphere (IPMA) joined other countries in the North-eastern Atlantic, the Mediterranean and Connected Seas (NEAM) region as participants in an international tsunami response exercise. The exercise, titled NEAMWave12, simulated widespread Tsunami Watch situations throughout the NEAM region. It is the first international exercise as such, in this region, where the UNESCO-IOC ICG/NEAMTWS tsunami warning chain has been tested to a full scale for the first time with different systems. One of the systems is developed in the project Collaborative, Complex, and Critical Decision-Support in Evolving Crises (TRIDEC) and has been validated in this exercise among others by KOERI and IPMA. In TRIDEC new developments in Information and Communication Technology (ICT) are used to extend the existing platform realising a component-based technology framework for building distributed tsunami warning systems for deployment, e.g. in the North-eastern Atlantic, the Mediterranean and Connected Seas (NEAM) region. The TRIDEC system will be implemented in three phases, each with a demonstrator. Successively, the demonstrators are addressing related challenges. The first and second phase system demonstrator, deployed at KOERI's crisis management room and deployed at IPMA has been designed and implemented, firstly, to support plausible scenarios for the Turkish NTWC and for the Portuguese NTWC to demonstrate the treatment of simulated tsunami threats with an essential subset of a NTWC. Secondly, the feasibility and the potentials of the implemented approach are demonstrated covering ICG/NEAMTWS standard operations as well as tsunami detection and alerting functions beyond ICG/NEAMTWS requirements. The demonstrator presented addresses information management and decision-support processes for hypothetical tsunami-related crisis situations in the context of the ICG/NEAMTWS NEAMWave12 exercise for the Turkish and Portuguese tsunami exercise scenarios. Impressions gained with the standards compliant TRIDEC system during the exercise will be reported. The system version presented is based on event-driven architecture (EDA) and service-oriented architecture (SOA) concepts and is making use of relevant standards of the Open Geospatial Consortium (OGC), the World Wide Web Consortium (W3C) and the Organization for the Advancement of Structured Information Standards (OASIS). In this way the system continuously gathers, processes and displays events and data coming from open sensor platforms to enable operators to quickly decide whether an early warning is necessary and to send personalized warning messages to the authorities and the population at large through a wide range of communication channels. The system integrates OGC Sensor Web Enablement (SWE) compliant sensor systems for the rapid detection of hazardous events, like earthquakes, sea level anomalies, ocean floor occurrences, and ground displacements. Using OGC Web Map Service (WMS) and Web Feature Service (WFS) spatial data are utilized to depict the situation picture. The integration of a simulation system to identify affected areas is considered using the OGC Web Processing Service (WPS). Warning messages are compiled and transmitted in the OASIS Common Alerting Protocol (CAP) together with addressing information defined via the OASIS Emergency Data Exchange Language - Distribution Element (EDXL-DE). This demonstration is linked with the talk 'Experiences with TRIDEC's Crisis Management Demonstrator in the Turkish NEAMWave12 exercise tsunami scenario' (EGU2013-2833) given in the session "Architecture of Future Tsunami Warning Systems" (NH5.6).

Partial sequence analysis of an atypical Turkish isolate provides further information on the evolutionary history of Plum pox virus (PPV).  

PubMed

A variety of techniques, such as typing with subgroup-specific monoclonal antibodies, restriction length polymorphism (RFLP) analysis or subgroup-specific RT-PCR are available for the discrimination of Plum pox virus (PPV) isolates. However, the existence of PPV isolates showing abnormal typing properties has been observed in the past [Candresse, T., Cambra, M., Dallot, S., Lanneau, M., Asensio, M., Gorris, M.T., Revers, F., Macquaire, G., Olmos, A., Boscia, D., Quiot J.B., Dunez, J., 1998. Comparison of monoclonal antibodies and polymerase chain reaction assays for the typing of isolates belonging to the D and M serotypes of Plum pox potyvirus. Phytopathology 88, 198-204.]. In an effort to understand the molecular mechanisms underlying such anomalous serological and molecular typing characteristics, partial 3' (1449 nt) and 5' (3706 nt) sequences have been determined for an atypical Turkish PPV isolate (Abricotier Turquie or Ab-Tk). The results obtained indicate that its unusual typing behaviour is caused by point mutations affecting key restriction sites and epitopes and confirm that this isolate represents a divergent member of the PPV-M subgroup. In addition, analysis of the partial Ab-Tk genomic sequences demonstrated that the 5' region of the genome of this isolate has a mosaic structure resulting from recombination event(s), shedding new light on the evolutionary history of Plum pox virus.

Acid-bile, antibiotic resistance and inhibitory properties of propionibacteria isolated from Turkish traditional home-made cheeses.  

PubMed

In this study, a total of 29 Propionibacterium spp. were isolated from traditional home-made Turkish cheese samples. As a result of the identification, isolates were identified as Propionibacterium freudenreichii subsp. freudenreichii (15 strains), Propionibacterium jensenii (12), and Propionibacterium thoenii (2). All isolates and 5 reference strains were examined for their abilities to survive at pH 2.0, 3.0, 4.0, 5.0 and in the presence of 0.06, 0.15 and 0.30% bile salts, their influence on the growth of food-borne and spoilage bacteria, as well as their sensitivity against 11 selected antibiotics. Only seven propionibacteria strains survived in both the acidic and bile salt environments. Propionibacterium spp. strains strongly inhibited growth of the Escherichia coli ATCC 11229 and Shigella sonnei Mu:57 strains (91%). All propionibacteria strains were sensitive to a majority of the antibiotics used in the investigations. Overall, dairy propionibacteria showed high antibacterial activity, resistance to pH 4.0, 5.0, high resistance to bile salts and will provide an alternative source to Lactobacillus and Bifidobacterium as probiotic culture.

Two new beta-thalassemia deletions compromising prenatal diagnosis in an Italian and a Turkish couple seeking prevention.  

PubMed

When the molecular background of couples requesting prevention is unclear, family analysis and tools to define rare mutations are essential. We report two novel deletion defects observed in an Italian and in a Turkish couple. The first proband presented with microcytic hypochromic parameters without iron deficiency, a normal HbA(2) and an elevated HbF (10.6%). His father presented with a similar phenotype and his wife was heterozygous for the common Mediterranean codon 39 (HBB:c.118C>T) mutation. Having excluded point mutations and common deletions, Multiplex Ligation-dependent Probe Amplification was performed revealing an unknown Ggamma(Agammadeltabeta)(0)-thalassemia defect spanning from the Agamma gene to downstream of the beta-globin gene provisionally named Leiden 69.5 kb deletion. In the second case, the wife presented with a mild thalassemic picture, normal HbA(2), elevated HbF (18.5%) and a beta/alpha globin chain synthesis ratio of 0.62, without iron deficiency or any known beta-thalassemia defect, while the husband was a simple carrier of the common Mediterranean IVS-I-110 (HBB:c.93-21 G>A) mutation. A new large deletion involving the beta-gene and part of the delta-gene was identified by Multiplex Ligation-dependent Probe Amplification provisionally named "Leiden 7.4 kb". PMID:19734421

Assessing the Validity and Reliability of a Questionnaire on Dietary Fibre-related Knowledge in a Turkish Student Population  

PubMed Central

This study aimed to validate a questionnaire on dietary fibre (DF)-related knowledge in a Turkish student population. Participants (n=360) were either undergraduate students who have taken a nutrition course for 14 weeks (n=174) or those in another group who have not taken such a nutrition course (n=186). Test-retest reliability, internal reliability, and construct validity of the questionnaire were determined. Overall internal reliability (Cronbach's alpha=0.90) and test-retest reliability (0.90) were high. Significant differences (p<0.001) between the scores of the two groups of students indicated that the questionnaire had satisfactory construct validity. It was found that one-fifth of the students were unsure of the correct answer for any item, and 52.5% of them were not aware that DF had to be consumed on a daily basis. Only 36.4 to 44.2% of the students were able to correctly identify the food sources of DF. PMID:24592591

How does locus of control and inflated sense of responsibility relate to obsessive-compulsive symptoms in Turkish adolescents?  

PubMed

This study aimed to examine the effects of responsibility attitudes, locus of control and their interactions on the general obsessive-compulsive (OC) symptomatology and the dimensions of OC symptoms in a sample of Turkish adolescents (n=385), their ages varied from 16 to 20 with a mean of 17.23 (S.D.=.68). The results of the present study revealed a significantly positive relationship between responsibility attitudes and general OC symptomatology. However, locus of control did not appear as a significant predictor of general OC symptomatology. Furthermore, results revealed that there was a significant interaction effect of responsibility attitudes with locus of control on OC symptomatology. That is, an inflated sense of responsibility and the presence of an external locus of control produced the highest level of OC symptoms. Related to the dimensions of OC symptoms, responsibility was a weak predictor of obsessive thinking symptoms, and a moderate predictor of cleanliness and checking symptoms. Locus of control and its interaction with responsibility attitudes only significantly predicted obsessional thinking symptoms. PMID:18304779

C.428_451 dup(24bp) mutation of the ARX gene detected in a Turkish family.  

PubMed

ARX mutations give rise to both syndromic and nonsyndromic forms of mental retardation (MR). We investigated the most common ARX mutations, c.428_451 dup(24bp) and c.333ins (GCG)7 in a series of 370 mentally retarded FMR1 (CGG)n expansion mutation negative Turkish patients using PCR amplification and high resolution MetaPhor agarose gel electrophoresis. Sequence analysis was also performed for confirmation and discrimination of the mutations. One patient representing non-syndromic X-linked MR showed an abnormal band pattern on agarose gel and sequence analysis of exon 2 of the ARX gene revealed that the patient had the c.428_451 dup(24bp) mutation. When we screened the family members, we found that his sister and mother were also carrier for the same mutation. The proband showed mild MR and subtle clinical findings like dysarthria and lack of fine motor functions. In conclusion, the patients with weak fine motor skills and positive family history for X-linked MR should be screened for the most common ARX gene mutations. PMID:23072184

The effect of genetic polymorphisms of TLR2 and TLR4 in Turkish patients with coronary artery disease.  

PubMed

Coronary artery disease (CAD), being a multifactorial disease process, has been suggested to be associated by the interaction of both environmental and genetic risk factors. Toll-like receptors (TLRs) are related to the receptors of the innate immune system which serves as the recognition of the conserved pathogen motifs and the activation of the signals that stimulate inflammatory genes. In this study, we investigated the relationship between the polymorphisms in the TLR2-Arg753Gly, TLR4-Asp299Gly and Thr399Ile gene and CAD. The study population consisted of 300 patients (149 men, 151 women) with angiographically documented CAD. The polymorphisms were genotyped by real time PCR. No association between TLR2-Arg677Trp or TLR4-Asp299Gly and -Thr399Ile gene polymorphisms and the presence or the severity of CAD was observed. On the other hand, the TLR2-Arg753Arg genotype seemed to have a protective effect against development of CAD (OR=0.17; 95% CI=0.04-0.83). Our findings suggest that TLR2-Arg753Gly polymorphism is associated with CAD susceptibility in Turkish patients. PMID:25542811

Prevalence of genital warts in reproductive-aged Turkish women presenting at gynecology outpatient clinics for any reason.  

PubMed

The objective of this multicenter descriptive study was to calculate the frequency of genital warts among Turkish women aged 15-49 years, who visited outpatient gynecology clinics for a variety of reasons. The study was conducted in February 2011 to collect data for a minimum of 154 patients at each center, and the total sample size reached 2,967 women (95.1% completion rate). Oral informed consents were obtained. A questionnaire including data on socio-demographic characteristics and reasons for admission was administered, and a pelvic examination was performed. The overall point prevalence was 35% (95% CI = 3.1%-4.0%), correcting for sampling design, with the highest rates observed in the 15 to 19-year-old group. The odds of having a genital wart was 1.82 times (95% CI = 0.99-3.33) higher among non-pregnant participants than in pregnant women (p = 0.051). The overall point prevalence of genital warts among reproductive-aged women attending gynecology outpatient clinics for any reason in Turkey was 35%. PMID:24283176

Barcoding Turkish Culex mosquitoes to facilitate arbovirus vector incrimination studies reveals hidden diversity and new potential vectors.  

PubMed

As a precursor to planned arboviral vector incrimination studies, an integrated systematics approach was adopted using morphology and DNA barcoding to examine the Culex fauna present in Turkey. The mitochondrial COI gene (658bp) were sequenced from 185 specimens collected across 11 Turkish provinces, as well as from colony material. Although by morphology only 9 species were recognised, DNA barcoding recovered 13 distinct species including: Cx. (Barraudius) modestus, Cx. (Culex) laticinctus, Cx. (Cux.) mimeticus, Cx. (Cux.) perexiguus, Cx. (Cux.) pipiens, Cx. (Cux.) pipiens form molestus, Cx. (Cux.) quinquefasciatus, Cx. (Cux.) theileri, Cx. (Cux.) torrentium, Cx. (Cux.) tritaeniorhynchus and Cx. (Maillotia) hortensis. The taxon formerly identified as Cx. (Neoculex) territans was shown to comprise two distinct species, neither of which correspond to Cx. territans s.s. These include Cx. (Neo.) impudicus and another uncertain species, which may be Cx. (Neo.) europaeus or Cx. (Neo.) martinii (herein=Cx. (Neo.) sp. 1). Detailed examination of the Pipiens Group revealed Cx. pipiens, Cx. pipiens f. molestus and the widespread presence of the highly efficient West Nile virus vector Cx. quinquefasciatus for the first time. Four new country records are reported, increasing the Culex of Turkey to 15 recognised species and Cx. pipiens f. molestus. A new taxonomic checklist is provided, annotated with respective vector competencies for transmission of arboviruses. PMID:25446171

Mutations in the MSX1 gene in Turkish children with non-syndromic tooth agenesis and other dental anomalies  

PubMed Central

Aim: To search for mutations on the MSX1 gene and to present a genetic basis for non-syndromic tooth agenesis in conjunction with dental anomalies in a Turkish population. Materials and Methods: The patients included in this study were otherwise healthy, with ages ranging from seven to eighteen years. Eighty-two of them had one to six teeth missing (Group I) and 26 had more than six teeth missing (Group II), except for the third molars,. The missing teeth and dental anomalies were examined clinically and radiographically. The MSX1 gene was sequenced from the blood samples of patients who consented to the study. Results: Mutations or polymorphisms on the MSX1 gene were identified in six patients. Taurodontism was seen in patients from both groups I and II. The nucleotide changes were identified by mutation screening. Conclusions: Performing family studies, screening other candidate genes, and investigation of interactions between genes will provide a basis for better analysis of tooth agenesis models and their association with other dental anomalies.

Assessment of Individual Susceptibility to Baseline DNA and Cytogenetic Damage in a Healthy Turkish Population: Evaluation with Lifestyle Factors  

PubMed Central

Background: Cytogenetic biomarkers are most frequently used well-established endpoints in human population studies with their sensitivity for measuring exposure to genotoxic agents. They have an important role as early predictors of cancer risk. Identification of individual genotypes of metabolic gene polymorphisms helps to understand the modulation of cancer susceptibility by environmental exposures, such as cigarette smoking and other lifestyle factors. Aim: To evaluate individual susceptibility to chemicals, we determined individual DNA damage related to glutathione S-transferase (GST) genotypes (GSTM1, GSTT1, and GSTP1) in a Turkish population. Methods: Peripheral blood lymphocytes (PBL) and DNA samples of 127 subjects were analyzed for the presence of DNA damage, using single-cell gel electrophoresis (the Comet assay), and for cytogenetic parameters (chromosomal aberrations [CAs], bleomycin-induced CA, and a cytokinesis-blocked micronucleus assay), and the polymerase chain reaction/restriction fragment length polymorphism method, respectively. Results: Individuals carrying a GSTT1-null allele showed higher frequencies of CA and micronucleus (MN) (p=0.026, p=0.003, respectively), whereas the GSTM1-null and GSTP1 mutant genotypes did not show any differences in cytogenetic parameters. Our findings demonstrated that none of the lifestyle factors (smoking, alcohol drinking, dietary habits, vitamin intake, and physical activity), except for vitamin intake (p=0.002), were significantly associated with the studied cytogenetic parameters. Conclusion: Our results suggest that the GSTT1 gene polymorphism may influence the baseline cytogenetic frequency in a healthy population. PMID:22905990

Evaluation of Clinical Course and Neurocognition in Children With Self-Limited Infantile Epilepsy in a Turkish Cohort Study.  

PubMed

The outcome of children with self-limited infantile epilepsy was reported to be normal psychosocial and cognitive development as a characteristic criterion. We aimed to investigate the clinical course and neurocognitive outcome in children with self-limited infantile epilepsy in a Turkish cohort. The clinical course, electroencephalographic (EEG) characteristics, neuroimaging, treatment, and outcome of children with self-limited infantile epilepsy were retrospectively analyzed. All infants were reevaluated with the Denver Developmental Screening Test in addition to neurologic examination. Of 44 patients, self-limited familial infantile epilepsy was diagnosed in 8 infants (18.2%) and self-limited nonfamilial infantile epilepsy in 28 (63.6%). Interictal EEGs and neurologic examinations were normal in all cases. Fine motor and gross motor skills, language, adaptive personal/social skills were near-normal in all patients with self-limited familial infantile epilepsy. Delay in language parameters was observed in 2 infants with self-limited nonfamilial infantile epilepsy. Language skills should be thoroughly evaluated with detailed neurocognitive screening tests in patients with self-limited infantile epilepsy. PMID:24958006

Characterization of carbonic anhydrase from Turkish native "Gerze" chicken and influences of metal ions on enzyme activity.  

PubMed

Abstract Carbonic anhydrase was purified and characterized from erythrocytes of the Turkish native chicken, Gerze, for the first time. The enzyme was purified 57.65-fold with a yield of 52%, and a specific activity of 954.08 U/mg proteins having optimum pH at 8.0; optimum temperature at 30?°C; optimum ionic strength at 10 mM and stable pH at 8.0. The purified enzyme had apparent KM and Vmax values of 0.73 mM and 0.236 ?mol?× min(-1), respectively. Al(+3), Hg(+2), Cu(+2), Pb(+2), and Cd(+2) showed inhibitory effects on the enzyme. Pb(+2) exhibited the strongest inhibitory action. Cd(+2) and Hg(+2) were moderate inhibitor, whereas Al(+3) and Cu(+2) showed weaker actions. All tested metals inhibited the enzyme in competitive manner. Our findings indicate that these metals inhibit the chicken enzyme in a similar manner to other ?-CAs from mammals investigated earlier, but susceptibility to various metals differ between the native chicken and other mammalian enzymes.

Impact of genetic factors (CYP2C9, VKORC1 and CYP4F2) on warfarin dose requirement in the Turkish population.  

PubMed

Warfarin has a narrow therapeutic index and displays marked person-to-person variation in dose requirement. Functional polymorphisms at candidate genes can therefore offer utility as biomarkers to individualize warfarin treatment. The main objective of this study was to determine whether and to what extent variability in warfarin dose requirements was determined by polymorphisms in CYP2C9, VKORC1, CYP4F2 (rs2108622) and EPHX1 (rs2292566) in the Turkish population. Patients (n = 107) who had stable doses and international normalized ratio (INRs) at their last three consecutive visits were registered. Their demographic factors, concurrent medications, warfarin-related bleedings or thromboembolisms, smoking, alcohol intake and weekly green vegetable consumption were recorded. From a blood sample, DNA was isolated and genotyped by real-time PCR for polymorphisms of CYP2C9, VKORC1, CYP4F2 and EPHX1. A regression analysis was used to determine the independent effects of genetic and non-genetic factors on warfarin dose optimization. In our study, in addition to age, genetic variants of CYP2C9, VKORC1 and CYP4F2 were found to be significant predictor variables for the maintenance dose for warfarin, explaining 39.3% of dose variability. VKORC1 and CYP2C9 genotypes remain predictor variables of the warfarin dose, and we first found that CYP4F2 (rs2108622) contributes to dose variability in the Turkish population as well. These observations may be of benefit to future translation research with a view to global personalized medicine in regions hitherto understudied such as the Turkish population so as to rationalize initial warfarin dose and reduce the burden of frequent INR measurements.

A Novel COL4A3 Mutation Causes Autosomal-Recessive Alport Syndrome in a Large Turkish Family  

PubMed Central

Background: Alport syndrome (AS) is a genetically heterogeneous disorder that is characterized by hematuria, progressive renal failure typically resulting in end-stage renal disease, sensorineural hearing loss, and variable ocular abnormalities. Only 15% of cases with AS are autosomal recessive and are caused by mutations in the COL4A3 or COL4A4 genes, encoding type IV collagen. Methods: Clinical data in a large consanguineous family with four affected members were reviewed, and genomic DNA was extracted. For mapping, 15 microsatellite markers flanking COL4A3, COL4A4, and COL4A5 in 16 family members were typed. For mutation screening, all coding exons of COL4A3 were polymerase chain reaction- amplified and Sanger-sequenced from genomic DNA. Results: The disease locus was mapped to chromosome 2q36.3, where COL4A3 and COL4A4 reside. Sanger sequencing revealed a novel mis-sense mutation (c.2T>C; p.M1T) in exon 1 of COL4A3. The identified nucleotide change was not found in 100 healthy ethnicity-matched controls via Sanger sequencing. Conclusions: We present a large consanguineous Turkish family with AS that was found to have a COL4A3 mutation as the cause of the disease. Although the relationship between the various genotypes and phenotypes in AS has not been fully elucidated, detailed clinical and molecular analyses are helpful for providing data to be used in genetic counseling. It is important to identify new mutations to clarify their clinical importance, to assess the prognosis of the disease, and to avoid renal biopsy for final diagnosis. PMID:23297803

Frequency and distribution of early tooth loss and endodontic treatment needs of permanent first molars in a Turkish pediatric population  

PubMed Central

Objectives: The objective of this study is to evaluate the frequency and distribution of early tooth loss and endodontic treatment needs of permanent first molars in a Turkish pediatric population. Materials and Methods: A total of 7,895 panoramic radiographs taken for routine dental examination at the Department of Oral Maxillofacial Radiology between 2008 and 2012 years were investigated. Two independent specialists evaluated early tooth loss and endodontic treatment needs of permanent first molars using panoramic radiography and patient anamnesis forms. The teeth were classified according to the following data: (a) Missing teeth, (b) teeth requiring extraction, (c) endodontically treated teeth (ETT), (d) teeth requiring endodontic therapy. The data also classified according to four factors: Age group (6-12 and 13-16), gender (boy and girl), jaw (mandible and maxilla) and side (right and left). A Chi-square test was used for statistical analyses. Results: A total of 19,488 and 12,092 teeth were evaluated in the child group and adolescent group respectively. All data were higher in adolescents than children (P < 0.001). For gender factor, only ETT was higher in girls than it was in boys (P < 0.001). For the jaw factor, all data were higher (P < 0.001) in mandible than in the maxilla. For the side factor, no statistical difference existed between right and left. Conclusions: Early tooth loss and endodontic treatment needs of permanent first molars showed variability according to age groups and jaws. When the results were compared according to the side and gender factors, no statistical difference was found (P > 0.05) except with the data of ETT in gender groups. PMID:24966738

Twelve-year trends in the prevalence and risk factors of diabetes and prediabetes in Turkish adults.  

PubMed

There is concern about an emerging diabetes epidemic in Turkey. We aimed to determine the prevalence of diagnosed and undiagnosed diabetes, prediabetes and their 12-year trends and to identify risk factors for diabetes in the adult Turkish population. A cross-sectional, population-based survey, 'TURDEP-II' included 26,499 randomly sampled adults aged ? 20 years (response rate: 87 %). Fasting glucose and biochemical parameters were measured in all; then a OGTT was performed to identify diabetes and prediabetes in eligible participants. The prevalence of diabetes was 16.5 % (new 7.5 %), translating to 6.5 million adults with diabetes in Turkey. It was higher in women than men (p = 0.008). The age-standardized prevalence to the TURDEP-I population (performed in 1997-98) was 13.7 % (if same diagnostic definition was applied diabetes prevalence is calculated 11.4 %). The prevalence of isolated-IFG and impaired glucose tolerance (IGT), and combined prediabetes was 14.7, 7.9, and 8.2 %, respectively; and that of obesity 36 % and hypertension 31.4 %. Compared to TURDEP-I; the rate of increase for diabetes: 90 %, IGT: 106 %, obesity: 40 % and central obesity: 35 %, but hypertension decreased by 11 % during the last 12 years. In women age, waist, body mass index (BMI), hypertension, low education, and living environment; in men age, BMI, and hypertension were independently associated with an increased prevalence of diabetes. In women current smoking, and in men being single were associated with a reduced risk. These results from one of the largest nationally representative surveys carried out so far show that diabetes has rapidly become a major public health challenge in Turkey. The figures are alarming and underscore the urgent need for national programs to prevent diabetes, to manage the illness and thus prevent complications. PMID:23407904

Occurrence of Anisakis simplex sensu stricto in imported Atlantic mackerel (Scomber scombrus) represents a risk for Turkish consumers.  

PubMed

Anisakid larvae are a prevalent food-borne pathogen that has been found in numerous fish species destined for human consumption. The accidental consumption of infected raw or poorly cooked fish may cause gastroenteric diseases and allergies in humans. In spite of the fact that thorough cooking or freezing kills Anisakis worms, this method does not destroy their allergenic capacity. The presence of A. simplex (s.s.) in seafood products may present a health risk for consumers. In Turkey, Atlantic mackerels are marketed as frozen and mainly imported from Norway. The aim of this study was to identify the Anisakis species found in deep-frozen whole Atlantic mackerel (Scomber scombrus) destined for human consumption in fish markets that imported fish from Norway to Turkey. All Anisakis larvae isolated from imported Atlantic mackerel were identified via morphology as third larvae of Anisakis Type I. The ITS region (ITS-1, 5.8S subunit, ITS-2) was amplified and digested with the restriction enzymes Hinf I and Hha I. Larvae of the genus Anisakis were identified via PCR-RFLP as belonging to Anisakis simplex (s.s.), and this was confirmed by sequencing the cox2 gene. The overall prevalence of Anisakis larvae was 25% (95% confidence limits: 13-41%), and the mean intensity was 19.1 (bootstrap 95% confidence limits: 15.3-25.5). Recognized zoonotic A. simplex (s.s.) larvae found in imported Atlantic mackerel could represent a risk. Those who consume them could acquire parasitic allergies. The results will have an important impact on public health risk assessment in that they suggest reviewing critical control points at the Hazard Analysis Critical Control Point (HACCP) programmer to reduce the risk of anisakid-induced allergies among consumers. Consequently, the present study provides the first data regarding the occurrence of A. simplex (s.s.) larvae in imported Atlantic mackerel in Turkish markets. PMID:24935687

Familial acromegaly due to aryl hydrocarbon receptor-interacting protein (AIP) gene mutation in a Turkish cohort.  

PubMed

Aryl hydrocarbon receptor-interacting protein (AIP) is associated with 15-20% of familial isolated pituitary adenomas and 50-80% of cases with AIP mutation exhibit a somatotropinoma. Herein we report clinical characteristics of a large family where AIP R304X variants have been identified. AIP mutation analysis was performed on a large (n = 52) Turkish family across six generations. Sella MRIs of 30 family members were obtained. Basal pituitary hormone levels were evaluated in 13 family members harboring an AIP mutation. Thirteen of 52 family members (25%) were found to have a heterozygous nonsense germline R304X mutation in the AIP gene. Seven of the 13 mutation carriers (53.8%) had current or previous history of pituitary adenoma. Of these 7 mutation carriers, all but one had somatotropinoma/somatolactotropinoma (85.7% of the pituitary adenomas). Of the 6 acromegaly patients with AIP mutation (F/M: 3/3) the mean age at diagnosis of acromegaly was 32 ± 10.3 years while the mean age of symptom onset was 24.8 ± 9.9 years. Three of the six (50%) acromegaly cases with AIP mutation within the family presented with a macroadenoma and none presented with gigantism. Biochemical disease control was achieved in 66.6% (4/6) of the mutation carriers with acromegaly after a mean follow-up period of 18.6 ± 17.6 years. Common phenotypic characteristics of familial pituitary adenoma or somatotropinoma due to AIP mutation vary between families or even between individuals within a family. PMID:23743763

HLA-B51 subtypes in Turkish patients with Behçet's disease and their correlation with clinical manifestations.  

PubMed

Behçet's disease (BD) is a multisystemic inflammatory disease believed to be triggered by microbial or environmental factors on a genetic platform. Clinically, it may have an impact on many body systems, including the mucocutaneous, ocular, articular, vascular, and neurological systems. In this study, we aimed to determine the HLA-B51 subtypes and their correlations with the clinical findings of BD. Fifty-one patients with BD and 44 gender- and age-matched healthy subjects were included in this study. The HLA-B51 subtypes of all participants were determined, and the correlations of the clinical manifestations of the disease with the HLA-B51 subtypes were analyzed. HLA-B51 positivity was found to be significantly higher in the patient group (P < 0.001, RR = 15.20), which had significantly more frequent HLA-B5101, HLA-B5102(01), HLA-B5109, and HLA-B5122 subtypes than the healthy subjects (all P < 0.05). Furthermore, considering the correlation between the genetic makeup and clinical findings, the HLA-B5109 subtype was found to be less frequent in patients with papulopustular skin lesions (P = 0.042). The frequency of HLA-B5103 was significantly higher in patients with central nervous system involvement (P = 0.015). There may be a relationship between HLA-B5102(01), HLA-B5109, and HLA-B5122 in addition to HLA-B51 and HLA-B5101(01) in Turkish patients with BD. The HLA-B5109 subtype can be protective against papulopustular lesion development; however, the HLA-B5103 subtype may pose a risk for neuro-Behçet development in BD. PMID:25062414

Particulate and dissolved primary production along a pronounced hydrographic and trophic gradient (Turkish Straits System-NE Aegean Sea)  

NASA Astrophysics Data System (ADS)

The rates of particulate (PPp) and dissolved primary production (PPd) were estimated along a trajectory of variable environmental regimes formed in a narrow shelf area, following the course of Black Sea water masses (BSW) passing through the Turkish Straits System (TSS) into the NE Aegean Sea (BS-AS outflow). Seven stations in total were sampled, covering a transect from the eastern edge of the Marmara Sea basin to the NE Aegean Sea, during two consecutive cruises performed in October 2008 within the framework of the EU SESAME project. Along the BS-AS outflow, depth-integrated over the surface BSW layer PPp decreased considerably from 91 to < 16 mg C m- 2 h- 1 whereas PPd increased from 3 to 10 mg C m- 2 h- 1. As a consequence, the relative importance of PPd over total production (percentage extracellular release, PER) increased from 6% (± 3% sd) in the Marmara Sea to 37% (± 4% sd) in the NE Aegean Sea. Total chlorophyll a concentration gradually decreased and phytoplankton community size-structure was modified, with pico-phytoplankton, that originally represented 35% (± 9% sd) in the Marmara Sea, gradually becoming dominant in the NE Aegean (77% ± 2% sd), substituting large nano- and micro-phytoplankton cells (> 5 ?m). This study showed that PER increased along a gradient from mesotrophy to oligotrophy, probably due to nutrient deficiency constraining phytoplankton growth and was closely related to phytoplankton size-structure. In the oligotrophic NE Aegean Sea, phytoplankton exudation was a significant source of dissolved organic carbon for heterotrophic prokaryotes.

The Relationship Between Genetic Variations of the Cholesteryl Ester Transfer Protein Gene and Coronary Artery Disease in Turkish Subjects  

PubMed Central

Objective Although the relationship between cholesteryl ester transfer protein (CETP) and cholesterol metabolism has been characterized in recent years, the effect of CETP genetic variants associated with coronary artery disease (CAD) is still unclear. Therefore, we investigated the association between CETP gene polymorphism and levels of lipid in patients with CAD. Materials and Methods We conducted a case-control study that included 194 unrelated subjects who underwent coronary angiography for suspected ischemic heart disease. This group was divided into 96 patients with angiographically documented CAD and 98 subjects (individuals matched for age and gender) without angiographically documented CAD (CAD-free subjects), all of whom were studied to examine the genotypic distribution of the CETP gene polymorphism in CAD. Genotyping was performed via polymerase chain reaction. Results Of the 96 patients with CAD, 38 (40%) were B1B1, 42 (44%) B1B2 and 16 (16%) B2B2, compared with the control subjects, of which 35 (36%) were B1B1, 44 (45%) B1B2 and 19 (19%) B2B2. There were no significant differences between patients with CAD and control subjects in the distribution of the CETP gene polymorphism. Patients with the B1B1 genotype had lower high-density lipoprotein-cholesterol (HDL-C) and higher triglyceride (TG) levels than patients with the B2B2 genotype (p<0.05). In addition, among control subjects HDL-C levels were significantly higher in subjects with the B2B2 genotype than in subjects with the B1B1 genotype (p<0.01). Conclusion Our results suggest that genetic variations of the CTEP gene may be responsible for low HDL-C levels but may not be considered as a risk factor for CAD in the Turkish population.

IRS1 gene polymorphisms Gly972Arg and Ala513Pro are not associated with insulin resistance and type 2 diabetes risk in non-obese Turkish population  

PubMed Central

Insulin receptor substrate 1 (IRS1), plays a critical role in insulin signaling and its control has an important place in the development of insulin resistance. The tyrosine phosphorylation of IRS1 serves as docking molecules for downstream effectors such as Phosphatidylinositol 3-kinase and phosphotyrosine phosphatase-2. We focused on the Gly972Arg and Ala513Pro variants of the IRS1 gene, since these specific allelic variants are located near the Tyr-Met-X-Met (YMXM) motifs around Tyr987 and Tyr612. Thus, we aimed to investigate the effects of Gly972Arg/Ala513Pro polymorphisms in IRS1 gene on development of insulin resistance and the risk of type 2 diabetes in a non-obese Turkish population. This work included 306 individuals comprising 178 subjects with type 2 diabetes and 128 healthy subjects matched for body mass index. Gly972Arg/Ala513Pro polymorphisms had no effect on type 2 diabetes risk and its phenotypes (P > 0.05). Although IRS1 gene and its variants are associated with type 2 diabetes and insulin resistance in several studies worldwide, our data showed that there is no association between Gly972Arg and Ala513Pro variants in IRS1 and disease in Turkish population.

Reliability and validity of the Turkish version of the Structured Clinical Interview for DSM-IV Dissociative Disorders (SCID-D): a preliminary study.  

PubMed

A total of 34 consecutive patients with dissociative identity disorder or dissociative disorder not otherwise specified were evaluated using the Turkish version of the Structured Clinical Interview for DSM-IV Dissociative Disorders (SCID-D). They were compared with a matched control group composed of 34 patients who had a nondissociative psychiatric disorder. Interrater reliability was evaluated by 3 clinicians who assessed videotaped interviews conducted with 5 dissociative and 5 nondissociative patients. All subjects who were previously diagnosed by clinicians as having a dissociative disorder were identified as positive, and all subjects who were previously diagnosed as not having a dissociative disorder were identified as negative. The scores of the main symptom clusters and the total score of the SCID-D differentiated dissociative patients from the nondissociative group. There were strong correlations between the SCID-D and the Dissociative Experiences Scale total and subscale scores. These results are promising for the validity and reliability of the Turkish version of the SCID-D. However, as the present study was conducted on a predominantly female sample with very severe dissociation, these findings should not be generalized to male patients, to dissociative disorders other than dissociative identity disorder, or to broader clinical or nonclinical populations.

Quality of life in multiple sclerosis patients with urinary disorders: reliability and validity of the Turkish version of King's Health Questionnaire.  

PubMed

MS patients frequently present with urinary system symptoms, which have a negative effect on the quality life. The aim of our study was to demonstrate the validity and reliability of the Turkish King's Health Questionnaire (KHQ) in MS patients. The study included 37 patients. For analysis of test-retest reliability, the Turkish version of the KHQ developed and the "translation-back translation" method was performed. To assess the validity of these results, Multiple Sclerosis Quality of Life Scale (MQoL-54) and Expanded Disability Status Scale (EDSS) were used. The internal consistency (intra-class correlation coefficient: 0.59-0.94) and test-retest reliability (Cronbach's ?-score 0.59-0.94) of KHQ were found to be high (p < 0.05). A significant correlation was detected between most of the KHQ subscores and the physical and mental MQoL-54 and EDSS (total and bowel/bladder, p < 0.05) subscores. The KHQ may be used to determine the effect of incontinence on the quality of life for MS patients. PMID:21479614
