    Objective: To evaluate the blood flow of the umbilical vein and right portal vein in macrosomic fetuses of diabetic mothers and investigate the effect of maternal insulin treatment on these blood flows.Material and Methods: This prospective case-control study was con- ducted between March 2019 and December 2019. Fetuses of the 49 pregestational and gestational diabetic mothers who had an abdominal cir- cumference percentile above 97% were evaluated as macrosomic and formed the study group. The study group was divided into two subgroups: patients treated with insulin and those who did not. In the control group, 48 non-diabetic pregnant women with matched gestatio nal weeks whose fetuses are at the 10-90% percentile were included. Time-averaged maximum blood velocity (TAMXV) values of the right portal vein and the free loop of the umbilical vein were measured.Results: The median right portal vein TAMXV value and umbilical vein TAMXV value were found to be significantly higher in diabetic pregnancies (16.25 cm/s, and 15.28 cm/s, respectively) than in the control group (12.76 cm/s, and 13.38 cm/s, respectively, p<0.001). Umbilical and right portal vein flows were similar in macrosomic fetuses of diabetic mothers who were treated with insulin or those who did not. While umbilical vein flow in macrosomic fetuses increased as the gestational age pro gressed (p=0.028), it was observed steadily in normally growing fetuses. Conclusion: The umbilical and right portal vein flows are higher in macro- somic fetuses of diabetic mothers than in appropriately grown fetuses. Maternal insulin treatment does not affect fetal umbilic al vein and right portal vein blood flow in macrosomic fetuses

    ive: To investigate the diagnostic value of blood flow measurements in spiral artery by transvaginal color Doppler sonography (CDS) in predicting endometrial pathologies.Methods: Ninety-seven patients presenting with abnormal uterine bleeding and requiring endometrial assessment were included in this prospective observational study. Endometrial thickness, structure and echogenicity were recorded. Pulsatility index (PI) and resistive index (RI) of the spiral artery were measured by transvaginal CDS. Endometrial sampling was performed for all subjects. Sonographic and hystopathologic findings were compared.Results: The histopathological diagnoses were as follows; 39 cases (40.2%) endometrial polyp, 9 cases (9.3%) endometrial hyperplasia, 10 cases (10.3) submucous myoma, 7 cases (7.2%) endometrium cancer, and 32 cases (33%) nonspecific findings. The spiral artery PI in endometrium cancer group was highly significantly lower than other groups (p<0.01). The spiral artery RI was also significantly lower in the patients with malignant histology (p<0.05). Conclusion: Endometrial pathologies are associated significantly with endometrial spiral artery Doppler changes.Key words: Spiral artery, Doppler ultrasonography, endometriu

    SAHİPLİK YAPISI İLE TEMETTÜ POLİTİKASI ARASINDAKİ İLİŞKİ: BORSA ISTANBUL'DAN (BIST) DENEYSEL BULGULAR Temettü politikası, finans alanında en çok tartışılan konulardan bir tanesi ve temettü dağıtım kararı da kurumsal yönetim politikasının en önemli bileşenlerinden bir tanesidir. Bu bağlamda temettü politikası, bu tezin özünü oluşturan kurumsal sahiplik yapısı tarafından da etkilenen en önemli kararlardan bir tanesidir. Sahiplik yapısının finansal olmayan firmaların temettü dağıtım politikası üzerindeki etkisi 1980'li yılların başından itibaren daha önce hiç olmadığı kadar ilgi çekmektedir. Bu zamana kadar alanının önde gelen akademisyenleri ve araştırmacıları çabalarını daha çok gelişmiş ülkeler üzerindeki çalışmalara yoğunlaştırmıştı. Halbuki, dünya küreselleştikçe ve gelişmiş ülkeler sermaye yatırımlarından daha fazla pay aldıkça küresel yatırımcılar ve araştırmacılar da gelişmekte olan ülkelerin temettü dağıtım politikalarıyla daha fazla ilgilenmeye başladılar.Bu çalışmanın ana amacı çeşitli sahiplik yapılarının seçilen firmalar üzerindeki etkilerini belirlemektir. Buna ek olarak bir başka amaç ise halka açık şirketlerin 1994, 2001 ve 2008’de yaşanan finansal krizler sonucunda izledikleri temettü politikalarını da araştırmaktadır. Bu çalışma ayrıca Borsa Istanbul'a kayıtlı firmaların temettü istikrarını temettü politikalarının ana unsuru olarak görüp görmediklerini firmaların temettü politika davranışlarını analiz ederek belirlemeye çalışmaktadır. Borsa Istanbul'da (BIST) yer alan, finansal olmayan ve 2004-2012 yılları arasındaki 9 yıllık dönemde en az 5 yıl temettü dağıtan 78 şirketle yapılan bu çalışma, sahiplik yapısının temettü politikası üzerindeki etkisini incelemeyi amaçlamaktadır. Bu amaçla temettü dağıtım oranı bağımlı değişken olarak seçilmiştir. Sahiplik yoğunluğu, yabancı sahiplik ve yönetimsel sahiplik bağımsız değişkenler olarak seçilirken, özkaynak karlılığı ve firma büyüklüğü ise kontrol değişkenleri olarak çalışmaya dahil edilmiştir. Yapılan dengesiz panel veri analizi sonuçlarına göre ise temettü dağıtım oranı ile sahiplik yoğunluğu, yabancı sahiplik ve firma büyüklüğü arasında pozitif anlamlı bir ilişki tespit edilmiştir. Yönetimsel sahiplik ve özkaynak karlılığı ile temettü dağıtım oranı arasında ise anlamlı negatif bir ilişki olduğu tespit edilmiştir.

ABSTRACT THE RELATIONSHIP BETWEEN OWNERSHIP STRUCTURE AND DIVIDEND POLICY : EMPIRICAL EVIDENCE FROM BORSA ISTANBUL (BIST) Dividend policy is one of the most frequently researched areas in the field of finance and dividend payout decision is an important element of corporate policy. Within this context, dividend policy is one of the firm's major decisions that is influenced by corporate ownership structure, which is the core of this study. The effect of ownership structure on the dividend policies of the non-financial firms attracts as much attention as has never before since the beginning of 1980s. Until this time, academicians and researchers have concentrated their efforts mostly on developed nations. However, as the world have become more globalized and as the emerging countries have received a higher proportion from the global equity investments, investors have also started to pay more attention to the dividend policies of emerging markets. The main goal of this study is to determine the impact of various ownership structures on dividend policies of the selected non-financial corporations. Additionally, another aim is to investigate the dividend policies of publicly traded corporations that they implemented as a result of the major financial crises experienced in 1994, 2001 and 2008. This study also tries to analyze the dividend policy behaviors of the companies registered to the Borsa Istanbul 100 Index to evaluate the perceptions of those companies to see whether they view dividend stability as an essential element of their dividend policies. This study, which was conducted with the 78 non-financial companies traded at the Borsa Istanbul (BIST) and distributed at least 5 years of dividends in the nine-year period between 2004 and 2012, aims to investigate the ownership structure on dividend payout policy. For this aim, dividend payout ratio has been selected as the dependent variable. While the ownership concentration, foreign ownership and managerial ownership have been selected as the independent variables, return on equity (ROE) and firm size have been selected as the control variables. According to the results of the unbalanced panel data analysis, significant positive relationship has been determined between the variables of ownership concentration, foreign ownership and firm size and dividend payout ratio. Significant negative relationship has been detected between the variables of managerial ownership, return on equity (ROE) and dividend payout ratio.

    To compare perinatal outcomes of growth-restricted fetuses with bilateral positive end-diastolic (PED) flow at the perivesical segment (PVC) and growth-restricted fetuses with unilateral or bilateral absent/reverse end-diastolic (ARED) flow at the PVC segment. A total of 119 growth-restricted fetuses with PED flow at the free loop of the umbilical artery were enrolled in this cross-sectional study. Methods The patients were separated into three groups according to presence or absence of the end-diastolic flow at the perivesical segment. Patients with bilateral PED flow at the PVC segment were enrolled in Group1, patients with unilateral and bilateral (ARED) flow at the PVC segment were enrolled in Group 2 and 3, respectively. The perinatal outcomes of the groups were investigated. There were no significant differences between groups in terms of maternal age, gravida, parity, the gestational age at ultrasound examination and the pulsatility index of free umbilical artery. The gestational age at delivery, the birth weight and the interval between the diagnosis and delivery were found significantly higher in Group 1 than the other groups, there were no significant differences between Group 2 and 3 in terms of these parameters. More adverse pregnancy outcomes were observed in the unilateral and bilateral ARED flow groups than the bilateral PED flow group. In addition to the free loop Doppler indices, measuring the umbilical arteries Doppler indices at the PVC segment could contribute to the determination of more growth-restricted fetuses at risk of hypoxia

    Ekonomik bir dayandırma yöntemi olan kurutma; yaş ürünlerdeki serbest suyu uzaklaştırarak ürünlerde meydana gelebilecek biyokimyasal reaksiyonların yavaşlatılmasıdır. Dünya’da bandırılmış (potasalı) ve bandırılmamış (naturel) olmak üzere başlıca iki tip çekirdeksiz kuru üzüm üretilmektedir. Bu çalışmada 2015 yılında Alaşehir (Manisa) bölgesinde sultaniye üzümü yetiştirilen 6 farklı bağdan hasat döneminde yaş üzümler toplanmıştır. Bu üzümlerin bir kısmı potasalı ve naturel olarak kurutulmuştur. Hem yaş üzümlerde hem de iki farklı şekilde kurutulan kuru üzümlerde pestisit analizleri gerçekleştirilmiştir. Analizler sonucunda her bağda en az 8 adet pestisit etken maddesi tespit edilmiştir. Bu bağlardan iki tanesinin yaş üzümünde, üç tanesinin de kuru üzümünde MRL (Maximum Residue Limit, Maksimum kalıntı miktarı) değerlerini aşmış en az bir adet pestisit etken maddesi bulunmaktadır. Pestisit etken maddelerinin tamamına yakını üzümler kurutulduğu zaman konsantrasyonlarında artış göstermiştir. Ayrıca potasalı kurutulan kuru üzümlerde natural kurutulan kuru üzümlere kıyasla daha yüksek konsantrasyonlarda pestisitler tespit edilmiştir

    Thyroid Storm Complicating Pregnancy, A Case Report and Management

    No full text
    The incidence of hyperthyroidism in pregnancy is between 0,05 % and 0,2%. Graves disease is the most common cause of hyperthyroidism in pregnancy. Decrease in Thyroid Stimulating Hormone(TSH) levels and increase in free thyroxine levels are used for diagnosis of thyrotoxicosis. If hyperthyroidism is not treated during pregnancy, these pregnancies are prone to both maternal and fetal complications. Here we present a case of thyrotoxicosis with some maternal and fetal complications. 37 year old woman ,G4P2A1 with 28 - 29 weeks of pregnancy admitted to our clinic with complaints of back pain, painful uterine contractions and low pelvic pressure. Her blood pressure was 200/120mmHg, pulse rate was 120/min. She had tremor and exolphtalmic eyes, diffuse edema on legs. On suspect of hyperthyroidism she was told to uncover her neck. A diffuse goiter on neck was examined. Her thyroid hormones were sent for control. Thyroid hormone levels were TSH:0,009 uIU/ml, Free T3 :17,2 pg/ml (2-4,4),Free T4:>6 ng/ml (0,9-1,7). On emergency consultation, she had the diagnosis of Basedow Graves complicated with thyroid storm and undertaken to emergency treatment. Her blood glucose levels were checked four times in a day regularly and she had fasting blood glucose levels >120mg/dl and postbrandial blood glucose levels >200mg/dl and with the diagnosis of gestational diabetes, she has been started on ınsuline therapy. After 3 months of treatment, she gave birth to 2700gr, 44cm, Apgar 7-8 fetus. Postpartum no maternal or fetal complications were seen. Postpartum at the first week the baby had hyperthyroidism symptoms with the placental transport of autoantibodies, therefore breast feeding was stopped and checked for hormone levels regularly. The baby is now under control for the possibility of expected hypothyroidism. In uncontrolled hyperthyroidism, preeclampsia, premature birth, abruptio placenta, intrauterine growth retardation, fetal hyperthyroidism, stillbirth rates increase. These complication rates fall with the treatment of hyperthyroidism. Not only IUGR, we think gestational diabetes mellitus and macrosomic or LGA(large for gestational age) fetus could be one of the results of hyperthyroidism and high metabolic state in pregnancy. Hyperthyroidism in pregnancy is more frequent in our country and may mimic many pregnancy related conditions and should be differentiated and managed carefully
