International Journal of Business and Management , 2012, DOI: 10.5539/ijbm.v7n5p40
Abstract: Turkish immigrants have always been an important dynamic for the social and business life in Germany since October 1961, “Agreement for Sending the Turkish Workers to Germany”. They have then started to become important players as entrepreneurs in the economy after 1990s. This study aims to analyze performance of Turkish and German companies in production and service industries operating in Germany by using financial analysis methodology, and it aims to compare the results. Using 2007 financial data, the empirical results show that Turkish firms in both industries take more liquidity risk than their German counterparts while they are using less leverage in order to finance their investments. Moreover, Turkish companies have less profitability than German companies with the effect of high cost of debt. Especially in service industry, Turkish firms have low level of return for a unit of risk and low level of output for a unit of input.

Journal of Tuberculosis Research (JTR) , 2014, DOI: 10.4236/jtr.2014.24019
Abstract: Background: We aim to determine the proportions and patterns of resistance to first-line drugs: isoniazid (H), rifampicin (R), ethambutol (E) and streptomycin (S) among pulmonary tuberculosis patients. Methods: Strains were obtained from 1584 culture positive pulmonary tuberculosis patients. All specimens were inoculated into Löwenstein-Jensen media (LJ) and TK selective; drug susceptibility tests (DST) were performed for first-line drugs. Results: Multidrug resistant (MDR) were detected in 146 (9.2%) isolates. Three hundred (18.9%) isolates were resistant to H; 220 (13.9%) to R; 168 (10.6%) to S; 137 (8.6%) to E. Any drug resistance was detected in 442 (27.9%) isolates. MDR rate was higher in male patients than females (P = 0.006). MDR rates were different according to the age groups (P = 0.02). The highest rate was in 35 - 44 years and the lowest rate was in 15 - 24 years. Conclusions: We found an association between middle age and male gender and MDR tuberculosis.

Psikiyatride Guncel Yaklasimlar , 2011,
Abstract: The present review seeks to identify and analyze qualitative studies that examined experiences of children whose parents have a mental illness. This study reported that children whose parents have a mental illness had some common experiences. These experiences may have negative effects on children’s coping skills, resilience to tough living conditions and ability to maintain their mental health. In spite of these negative conditions, some of these children have much more self-confidence, resilience and independence because of inner development and early maturation. Some effective intervention programs are needed to promote information to children and other family members about mental illness, coping behaviors. Availability of such psychiatric services and nation-wide programs with professionals to deal with these problems should be organized properly to increase quality of life of these children. Furthermore, qualitative researches that explore the experiences of children whose parents with mental illness should also be conducted in our country.
Value of real-time endobronchial ultrasound-guided transbronchial needle aspiration
Cetinkaya Erdogan,Gunluoglu Gulsah,Ozgul Akif,Gunluoglu Mehmet
Annals of Thoracic Medicine , 2011,
Abstract: Aim : The diagnostic value of real-time convex-probe endobronchial ultrasound (CP-EBUS)-guided transbronchial needle aspiration (TBNA) in mediastinal pathologies, and the factors influencing it are not clearly known. This study has been designed to examine factors affecting the efficacy and diagnostic value of CP-EBUS-TBNA. Methods : Patients (n = 321) with mediastinal mass or enlarged lymph node in the mediastinum, participated in this study, conducted between April 2007 and May 2009. Samples were obtained from the lesions using the TBNA method, with the guidance of CP-EBUS. Histopathologic (in all samples) and microbiologic (in 151 patients′ samples) evaluations were carried out. Biopsy using an appropriate surgical method was taken when the result of the TBNA procedure was nondiagnostic. Thirty-four patients were excluded from the analysis due to several reasons. The diagnostic efficacy of the procedure was analyzed in the remaining 287 patients. Results : The diagnostic rate was 92% (89.7% for the benign diseases and 92.6% for the malignant diseases (P = 0.59)). In granulomatous diseases, the rate was 96% for sarcoidosis and 79% for tuberculosis (P = 0.002). Patients in whom only one lymph node was sampled and in whom two or more lymph nodes were sampled had a diagnostic rate of 85% and 95%, respectively (P = 0.03). When left hilar nodes were sampled, a higher diagnostic rate was achieved (P = 0.01). Conclusions : CP-EBUS-guided TBNA has a high diagnostic rate. Sampling of at least two separate lymph nodes and the discovery of left hilar station in these lymph nodes increase the rate of diagnosis.

Abstract: A endometriose é definida como a presen a de glandulas endometriais e estroma fora da cavidade uterina. Essa doen a, comum nas mulheres, é geralmente observada durante os anos reprodutivos. Embora a pelve seja o sítio mais comum da endometriose em mulheres, a localiza o extrapélvica é menos frequente e ainda mais difícil de diagnosticar, em decorrência das apresenta es distintas. Neste artigo é descrito um caso de endometriose de cicatriz da parede abdominal. Endometriosis is defined as the presence of endometrial glands and stroma outside the uterine cavity. This disease is commonly observed in women, particularly those of reproductive age. The pelvis is the most common location for endometriosis. On the other hand, extrapelvic endometriosis, which is less common, is more difficult to diagnose because of the extreme differences in its presentation. In this article, we describe our experience of a case of endometriosis in an abdominal wall scar.

Emine IYIGUN,Hatice AYHAN,Sevinc TASTAN,Gulsah KOSE
Journal of Neurological Sciences , 2010,
Abstract: Objective This systematic review was done to evaluate studies that investigate effect of unshaved skin preparation on development of surgical area infection on patients having cranial surgery.Material and Method Review of the study was done by using keywords “t ra s z kraniyal cerrahi”, “unshaved neurosurgery”, “without shaving cranial surgery” in search engines and reference lists of included studies. The studies that were published in English and that examine relationship between skin preparation and development of surgical area infection in patients who had cranial surgery were included. Data was analyzed by using a standard data summarizing form.Results Within potentially related review, studies that were published between 1992-2009 were included into systematic review. 5 of the studies are in form of non-randomized controlled study and 9 of them are designed as semi-experimental study. Because of non-existence of control group in semi-experimental studies no results were reported about effect of unshaved skin preparation on development of surgical are infection. Nevertheless it was also expressed that there is no difference between groups in the studies that have a control group.Conclusion There is need for well-designed, randomized controlled studies that show the effect of unshaved skin preparation on the development of surgical area infection in patients having cranial surgery and that show contribution to adaptation of patient's routine life. It is thought that this systematic review will guide in the planning of studies that will be done on this topic.

Abstract: Objective. The aim of this study was to investigate protective effects of resveratrol, a strong antioxidant, against possible negative effects of chronic immobilization stress on testes of male rats histochemically, immunohistochemically, ultrastructurally, and biochemically. Material and Methods. Male Wistar rats were divided into 4 groups ( ). Group I, control group (C), was not exposed to stress. Group II, stress group (S), was exposed to chronic immobilization stress. In Group III, low dose resveratrol + stress group (LRS), rats were given 10?mg/kg/day resveratrol just before the stress application. In Group IV, high dose resveratrol + stress group (HRS), rats were given 20?mg/kg/day resveratrol just before the stress application. For chronic immobilization stress application animals were put in the plastic tubes (6?cm in diameter, 15?cm in length) during 32 days for 6 hours. All animals were sacrificed 18 hours after the last stress application. Results. Histochemical and ultrastructural investigations showed that in stress group there was germ cell deprivation in seminiferous tubules and increase of connective tissue on interstitial area. No significant changes were seen in low and high dose resveratrol groups. After immunohistochemical investigations, TUNEL (+) and Active Caspase-3 (+) cells were increased in seminiferous tubules of stress group compared with those control group, but they were decreased in low and high dose resveratrol groups. According to biochemically results, MDA, GSH, and testosterone levels in stress group showed no significant difference when compared with those of the other groups. Conclusion. The chronic immobilization stress increases oxidative stress and apoptosis and causes histological tissue damages; resveratrol can minimize the histological damage in testes significantly. 1. Introduction In this modern world, stress is an unavoidable phenomenon. Stressful situations can lead to many physiological and psychological alterations [1]. Adverse effects of stress on male reproductive system have already been described. Stauber showed how occupational stress in man could affect sperm concentration, motility, and morphology, with these effects being reverted after removal of the stress factor [2]. Apoptotic germ cell death is an important mechanism in testicular development [3] and elimination of germ cells under normal physiological and pathological conditions [4, 5]. It has been show that testicular germ cell apoptosis increases in experimental cryptorchidism [6], local heat stress [7], immobilisation stress [8–13],
