The geochemical and Sr-Nd-Pb isotope properties, as well as the Laser Ablation Inductively Coupled Plasma and Mass Spectrometry (LA-ICP-MS) U-Pb zircon age, of Erikar Monzogranite in the eastern Pontides, are primarily investigated in this study with the aim of determining its magma source and geodynamic evolution. The U-Pb zircon age obtained from Erikar Monzogranite is 78 +/- 1.5Ma, thereby reFLecting the age of monzogranite. The I-type Erikar Monzogranite comprises quartz, plagioclase (An(35-45)), orthoclase, muscovite, and biotite. The geochemical analyses of the Erikar Monzogranite indicate being medium K calc-alkaline, peraluminous, and resembling magmatic arc granite. The Erikar Monzogranite is enriched in large ion lithophile elements and light rare earth elements relative to high field strength elements. Chondrite-normalized rare earth element patterns have concave upward shapes (La-N/Yb-N 2.47-8.58) with pronounced negative Eu anomalies (Eu-N/Eu*=0.29-0.65). Initial epsilon Nd-(i) values vary between 1.85 and 2.18 and initial Sr-87/Sr-86 values between 0.7048 and 0.7067. Fractionation of plagioclase, hornblende, and apatite played an important role in the evolution of Erikar Monzogranite. The crystallization temperatures of the melts ranged from 770 degrees C to 919 degrees C based on zircon and apatite saturation temperatures. The geochemical and isotopic data suggest being generated by the partial melting of mafic lower crustal sources.

Background Cardiovascular complications are the leading causes of premature deaths in hemodialysis patients. Due to rapid changes in volume and electrolyte concentration following dialysis, the some electrocardiographic (ECG) changes or arrhythmias might be seen. Objective To investigate the acute effects of hemodialysis on the ECG parameters in patients with chronic end-stage renal disease (ESRD). Method We included the consecutive ESRD patients who underwent a hemodialysis. Before and after hemodialysis, some 12 lead ECG parameters were analyzed by two different cardiologists by using electronic digital caliper device. Results A total of 62 patients (mean 52 ± 15 years; 65% male) with ESRD undergoing hemodialysis were recruited to the study. P-wave amplitude, QRS amplitude, QRS duration, QTc dispersion, the sum of amplitudes in V1S + V5R derivations, total QRS amplitude, and duration were significantly greater in posthemodialysis patients compared to the prehemodialysis ones. However, T-wave amplitude and QTc duration were significantly lower in posthemodialysis patients. Conclusion The ECG changes including prolangated QRS and increased QTc interval after hemodialysis should be kept in mind and assessed carefully in ESRD patients. Prolongation of these parameters may prove to be a further noninvasive marker of susceptibility to ventricular arrhythmias. © 2014 Wiley Periodicals, Inc.

A foreign body such as a needle in the heart can be life-threatening. While this may occur accidentally, needles may be inserted into the body by psychiatric patients or in cases involving domestic violence. A needle can migrate through the thorax toward the heart. In drug users, needles may also reach the right ventricle via the peripheral veins. Cardiac injury can occur via the esophagus after swallowing a needle. The clinical outcome may vary from an asymptomatic situation to tamponade or shock, depending on how severely the cardiac structures are affected. In injuries involving the thorax, pneumothorax may cause sudden shortness of breath. Here, we report the case of a 34-year-old male prison inmate who accidentally lodged a pin in his left ventricle while asleep. As he has refused surgery, it was decided to follow the patient carefully. © 2012, Wiley Periodicals, Inc.

Bu çalışmanın amacı, yerel yönetimlerin en önemli katılım araçlarından biri olan kent konseylerini, kadın meclisleri boyutundan incelemektir. İstanbul’un iki farklı parti tipolojisine ve nispeten uzun dönemdir aktif bir kent konseyine sahip Şişli ve Silivri ilçe belediyeleri çalışmanın kapsamını oluşturmaktadır. Sosyal bilimlerde nitel analiz yöntemlerinden anket ve mülakat tekniklerine başvurulan çalışmada Silivri Belediyesi ve Şişli Belediyesi Kent Konseyi Kadın Meclislerinde (KKKM) bulunan, bulunmuş ve mecliste etkili olmuş 40 kişi ile 40 anket ve 25 mülakat çalışması gerçekleştirilmiştir. Çalışma sonucunda elde edilen sonuçlar kent konseyine dahil olma, katılım, kurum içi yönetişim, kent konseyinin belediye ile ilişkisi ve özerklik başlıkları altında değerlendirilmiştir. Çalışma sonunda, katılımcıların kent konseyine dahil oluşunda kurum temsili, arkadaş-sosyal çevre etkisi ve ekonomik çıkarların etkili olduğu, kent konseylerinin yerel katılım konusunda etkili bir organ olduğu, konsey içerisinde alt meclislerin oluşturulmasında demokratik bir süreç izlendiği, ayni destek konusunda belediye ile iyi ilişkiler kurduğu ve kararlarında özerk hareket edebildiği gözlemlenmiştir. Bu bulguların yanı sıra çalışma kapsamındaki iki KKKM arasında yapılan çapraz analizlerde Şişli Belediyesi KKKM’de katılımda gönüllülük esasının daha ön plana çıktığı ve meclis içi alınan kararlarda daha demokratik bir süreç izlendiği, Silivri Belediyesi KKKM’de ise ekonomik kaygıların ve siyasi vesayetin etkili olduğu gözlemlenmiştir. Bu çalışma, kent konseylerinin deneyimleri ve yapılarından ziyade bir alt meclis olan kadın meclislerini kapsaması nedeniyle literatüre özgün bir katkı sunmaktadır. The aim of this study is to examine the city councils, one of the most important participation tools of local governments, from the perspective of its women's councils. Şişli and Silivri district municipalities, which have two different party typologies and an active city council for a relatively long period of time, constitute the scope of the study. In the study, in which survey and interview techniques, which are among the qualitative analysis methods in social sciences, were applied. 40 questionnaires and 25 interviews were conducted with 40 people who were in Silivri Municipality and Şişli Municipality City Council Women's Assemblies (CCWA) and were influential in the assembly. The results obtained as a result of the study were evaluated under the titles of being included in the city council, participation, internal governance, the relationship of the city council with the municipality and autonomy. The findings show that the representation of the institution, the effect of friends-social environment and economic interests are effective in the participation of the participants in the city council, the city councils are an effective organ in local participation, a democratic process is followed in the formation of the lower councils within the council, good relations with the municipality regarding in-kind support. It was obtained that CCWA can act autonomously in its own decisions. In addition to these findings, in the cross analyzes made between the two CCWA within the scope of the study, it was observed that the voluntary principle of participation in Şişli Municipality CCWA was more prominent and a more democratic process was followed in the decisions taken within the council, while economic concerns and political tutelage were effective in Silivri Municipality CCWA.This study makes a unique contribution to the literature because it covers women's councils, which is a lower assembly, rather than the experiences and structures of city councils.

Purpose: To investigate the influence of sex hormones on ocular haemodynamics, blood flow velocities in the ophthalmic and central retinal arteries and serum levels of sex hormones were measured in pre- and postmenopausal women. Methods: Colour Doppler imaging (CDI) was used to determine the flow velocities (peak systolic velocity [PSV] and end-diastolic velocity [EDV]) and the resistive index (RI) in the ophthalmic and central retinal arteries in 22 premenopausal and 32 postmenopausal women, who had never received hormone replacement therapy. Serum levels were measured for oestradiol, free testosterone and follicle-stimulating hormone. The CDI parameters were compared between the two groups and the influence of serum levels of oestradiol and testosterone on blood flow velocities and the resistive indices were analysed. Results: After correcting for age and mean arterial blood pressure, an analysis of covariance disclosed a significantly lower EDV (p = 0.02) and a significantly higher RI (p = 0.01) in the central retinal artery of postmenopausal women compared with premenopausal women. Partial correlation analysis, controlling for age, revealed significant correlations between the CDI parameters and serum levels of oestradiol and testosterone. For premenopausal women, PSV (r = 0.58, p = 0.04) and EDV (r = 0.73, p = 0.006) in the ophthalmic artery correlated positively with serum oestradiol levels. The RI in the central retinal artery decreased with increasing oestradiol levels in both groups (premenopausal r = - 0.40, p = 0.04; postmenopausal r = - 0.32, p = 0.05). Peak systolic velocity in the central retinal artery correlated negatively (r = - 0.49, p = 0.04), whereas the RI correlated positively (r = 0.53, p = 0.02) with testosterone levels in the premenopausal group. Postmenopausal women with higher testosterone levels had lower EDV (r = - 0.53, p = 0.007) in the central retinal artery and higher RI in both vessels (ophthalmic artery r = 0.48, p = 0.01; central retinal artery r = 0.61, p = 0.002). Conclusion: Our data provide evidence of a relationship between serum sex hormone levels and blood flow velocities and resistive indices in retrobulbar arteries. Oestradiol appears to have beneficial effects on ocular haemodynamics, whereas testosterone may act as an antagonistic to the effects of oestrogen.

BACKGROUND: Hyperprolactinemia has been reported to be associated with abnormalities of carbohydrate metabolism. The aim of this study was to evaluate the effects of hyperprolactinemia and bromocriptine (Brc) treatment on endothelial function, insulin sensitivity and inflammatory markers in pre-menopausal women. METHODS: Sixteen hyperprolactinemic pre-menopausal women with pituitary adenomas were recruited and 20 healthy subjects were included as controls. Patients were given Brc in doses of 2.5-20 mg/dl until normal levels of prolactin were reached. Prior to treatment and 2 months after prolactin levels were normalized, the following tests were performed. Insulin sensitivity was determined by an oral glucose tolerance test based on a formula named the insulin sensitivity index (ISI composite). Endothelial function was measured as flow-mediated dilatation (FMD) on a brachial artery using high resolution ultrasound. RESULTS: Serum glucose, insulin, estrogen, highly sensitive C-reactive protein (hsCRP), fibrinogen, homocysteine and uric acid levels were measured. Calculated ISI composite and FMD were significantly lower in the hyperprolactinemic group in comparison with the controls and improved after Brc treatment. Serum homocysteine, hsCRP and uric acid levels were significantly higher in hyperprolactinemic patients than in the controls and returned to normal levels with Brc treatment. Serum prolactin concentrations were inversely correlated with FMD measurements (r=-0.68; P
