Introduction: Hypertension targets many organs. This study investigates left ventricular hypertrophy (LVH), which can lead to conduction disorders, arrhythmias, and heart failure. Endothelial dysfunction (ED) was assessed using serum asymmetric dimethyl-arginine (ADMA) levels. Methods: The study included a total of 90 voluntary participants: 30 patients with hypertension and left ventricular hypertrophy, 30 hypertensive patients without hypertrophy, and 30 normotensive healthy controls. Serum ADMA levels were used to detect endothelial dysfunction. Results: The results showed that serum ADMA levels were significantly higher in the patient group compared to the control group. However, there was no significant difference in serum ADMA levels between the two subgroups of patients, with or without left ventricular hypertrophy (LVH). A correlation analysis was performed, revealing no correlation between serum ADMA levels and the left ventricular mass index (LVMI). Discussion and Conclusion: There appears to be no direct relationship between LVH and endothelial dysfunction. Furthermore, inflammatory processes seem to contribute to the development of LVH rather than endothelial dysfunction. The duration of exposure to high blood pressure and the stage of hypertension are also believed to impact this process. [ABSTRACT FROM AUTHOR]

Bu tezde Gaziantep Atık Su Arıtma Tesisinde çalışmakta olan biyogaz motorlu bir kojenerasyon sisteminin genetik algoritma temelli termodinamik optimizasyonu sunulmaktadır. Bu amaçla, Matlab programı kullanılarak kendi sistem kodlarımız geliştirilecektir. Kojenerasyon sistemi 1000 kW elektrik üretmekte ve havasız çürütme tankına ısı sağlamaktadır. Optimizasyon amacı olarak sistemin ekserji verimliliği seçilmiş ve sistem bileşenlerinin ekserji verimi optimize edilmiştir. Optimizasyon değişkenleri hava-yakıt karışım oranı, motor girişindeki hava-yakıt karışım basıncı ve motor soğutma suyunun motor çıkış sıcaklığı olarak seçilmiştir. Optimizasyonda elitlik ve rulet çarkı seçilim yöntemleri ayrı ayrı uygulanmıştır. Gaz motoru ekserji verimi, birinci yaklaşım için sadece yakıt girişi ve güç üretimi göz önüne alınarak, ikinci yaklaşım için ise birinci yaklaşıma ısıl etkilerin eklenmesi göz önüne alınarak belirlenmiştir. Gaz motorunun 1. ve 2. yaklaşıma göre ekserji verimleri elitlik yöntemiyle sırasıyla %23.5 ve %45.1 ve rulet çarkı yöntemiyle %26.7 ve %46.7 olarak bulunmuştur. Egzoz gazı ısı değiştiricisi ekserji verimi elitlik yöntemiyle %46.5 ve rulet çarkı yöntemiyle %43 olarak belirlenmiştir. Elitlik yöntemi ile 1 ve 2 numaralı ısı değiştiricilerinin ekserji verimleri sırasıyla %59 ve %56, rulet çarkı yönteminde %58.2 ve %56.5 olarak belirlenmiştir. Sistemin toplam ekserji verimi ise elitlik yöntemi ile %33.2 ve rulet çarkı yöntemiyle %33.5 olarak bulunmuştur. In this thesis, a genetic algorithm based thermodynamic optimization of biogas-powered cogeneration system which is active in GASKİ WWTP is presented. In this aim, our self-adaptive codes will be developed by using Matlab software. Cogeneration system produces 1000 kW electricity and supplies heat for anaerobic digestion. The objective of optimization is selected as exergy efficiency of the overall system and also exergy efficiencies of other components are optimized. Optimization variables are selected as air-fuel mixture ratio, the pressure of air-fuel mixture at the inlet of the gas engine and temperature of jacket cooling water at the outlet of the gas engine. Optimization is applied by using elitism and roulette wheel, separately. Gas engine exergy efficiency is determined by taking into account only the fuel input and power generation for the first approach, and by taking into account the addition of thermal effects to the first approach for the second approach. Exergy efficiency of the gas engine for 1st and 2nd approaches are found as 23.5% and 45.1% in elitism method and 26.7% and 46.7% in the roulette wheel method. Exergy efficiency of exhaust gas heat exchanger is determined 46.5% in elitism and 43% in roulette wheel. Exergy efficiencies of heat exchanger-1 and heat exchanger-2 are found to be 59% and 56% in elitism and 58.2% and 56.5% in roulette wheel, respectively. Overall exergy efficiency of the system is determined 33.2% in elitism and 33.5% in roulette wheel. 88

WOS: 000418781000003 PubMed ID: 28853103 Purpose: The first purpose of this study was to reveal factors affecting the postoperative development of systemic inflammatory response syndrome (SIRS) in patients undergoing standard percutaneous nephrolithotomy (PNL) for renal stones. The second purpose was to determine the role of the preoperative platelet-to-lymphocyte ratio (PLR) and the neutrophil-to-lymphocyte ratio (NLR) in the prediction of SIRS. Matarials and Methods: In total, 192 patients who had undergone conventional PNL for renal stones from 2013 to 2015 were included in the study. SIRS developed postoperatively in 41 (21.3%) patients. The patients were divided into SIRS and non-SIRS groups, and the effects of the PLR, NLR, and other demographic and operative data were investigated to predict the development of SIRS. Variables significant in the univariate analysis were evaluated using a multiple logistic regression model to determine the independent risk factors for developing SIRS after PNL. Results: Univariate analysis revealed significant differences in the preoperative PLR (P < .001), preoperative NLR (P = .018), number of access sites (P < .001), mean renal parenchymal thickness (P = .02), operative time (P < .001), decrease in hemoglobin (P = .016), length of hospital stay (P < .001), stone-free status (P = .023), and complication rate between the two groups of patients. However, multivariate analysis showed that only the PLR and the number of access sites were independent factors affecting the development of SIRS. When the PLR cut-off value was 114.1, development of SIRS was predicted with 80.4% sensitivity and 60.2% specificity. Conclusion: The preoperative PLR is an effective and inexpensive biomarker with which to predict SIRS after PNL. In particular, we recommend close monitoring of patients with a PLR of >114.1 because of the possible development of serious complications.

Amaç: Laparoskopik adrenalektomi, benign adrenal kitlelerin tedavisinde altın standart yöntem olarak kabul edilmektedir. Ancak birçok cerrah, benign adrenal kitle tedavisinde açık cerrahiyi tercih etmektedir. Bu tercihin nedeni, cerrahların laparoskopik adrenal cerrahinin ileri düzey laparoskopik cerrahi olduğunu ve öğrenme eğrisinin yüksek olduğunu düşünmeleri olabilir. Bu çalışmada, transperitoneal laparoskopik adrenalektomi cerrahisi sonuçlarımızı bildirmeyi amaçladık. Yöntemler: 2013 ile 2015 tarihleri arasında Namık Kemal Üniversitesi Tıp Fakültesi Hastanesin Üroloji Anabilim Dalında yapılmış olan laparoskopik adrenalektomi vakalarının verileri retrospektif olarak değerlendirildi. Hastaların demografik özellikleri, adrenal kitle patolojileri, kanama miktarı, hastanede kalış süreleri ve komplikasyonlar değerlendirildi. Bulgular: Toplam 21 hastanın verileri değerlendirildi. Bu hastaların 12’sine (%57,1) sağ adrenalektomi yapılırken, 9’una (%42,9) sol adrenalektomi uygulandı. Hastaların ortalama operasyon süresi 130,2±39, dk, ortalama kanama miktarı 197,6±72,4 ml ve ortalama hastanede kalış süresi 3,09±1,57 gün olarak tespit edildi. Patolojik değerlendirmede hastaların 4’ünde feokromasitoma, birinde miyeloma ve 16’sında adenoma olduğu tespit edildi. Boyut olarak 5 cm’den büyük kitlelerde kanama miktarı, operasyon süresi ve hastanede kalış süresi, 5 cm’den daha küçük kitlelere gore belirgin anlamda yüksek tespit edildi (p, Objective: Laparoscopic adrenalectomy is the gold standard surgical technique for benign adrenal tumors. On the other hand, most surgeons still prefer to perform open surgery for adrenal tumors. This may be related with the surgeons opinions that laparoscopic adrenalectomy is an advanced laparoscopic surgery and has a high learning curve. In this article we present the results of our initial transperitoneal laparoscopic adrenalectomy cases. Methods: Lateral transperitoneal laparoscopic adrenalectomy cases that were performed between 2013 and 2015, were retrospectively analyzed. Patients demographics, pathological types, operation time, blood loss, hospitalization time and complications were evaluated and compared with the literature. Results: A total of 21 patients were analyzed. Twelve (57.1%) patients had right and 9(42.9%) patients had left laparoscopic adrenalectomy. Mean operation time was 130.2±39.1 min, mean blood loss was 197.6±72.4 ml and mean hospitalization time was 3.09±1.57 days. Pathology reports of adrenal tumors were pheochromocytoma at 4 patients, myeloma at 1 patient and adenoma at 16 patients. Patients with tumor size > 5 cm had significantly higher blood loss, operation time and hospitalization time compared to tumors < 5 cm. (p

Synchronous bilateral upper urinary tract urothelial cancer (UTUC) is a very rare form of urothelial cancer. In patients with high-risk unilateral UTUC, radical nephroureterectomy (RNU) is the gold standard treatment. However, there is no consensus on the treatment for synchronous bilateral UTUC. Evaluation of the patient and the tumor is recommended. Bilateral nephron-sparing surgery (NSS) was performed on a 53-year-old patient who presented with high-risk synchronous bilateral UTUC, and the outcome was reported.

Cenk Murat Yazici, Omer Kurt Department of Urology, Namik Kemal University School of Medicine, Tekirdag, Turkey Abstract: Nocturia is the most bothersome lower urinary tract symptom. It has a multifactorial etiology. It had been thought nocturia was a nonspecific symptom of lower urinary system dysfunction, but it has been determined that many diseases, related to different organ systems, might be reasons for this nonspecific symptom. Along with the importance of systemic diseases that cause nocturia, the symptom itself has adverse effects on patients' health and quality of life. There are several studies reporting a direct relationship between nocturia and depression, cognitive dysfunction, mood disturbances, falls, and fractures. For this reason, it is important to treat nocturia both to increase quality of life and to decrease related complications. Treatment opportunities have been under investigation for 20 years. Most of the studies in the literature have reported the results of single-drug medication on nocturia, which may be insufficient for a situation that has such a multifactorial etiology. In this review, we evaluated the success of different treatment combinations on nocturia. Keywords: nocturia, combination, treatment, polyuria, lower urinary tract symptoms

Bediüzzaman Said Nursî hayatını Kur'an'a hizmet yolunda harcamış bir şahsiyettir. Ömrü boyunca Kur'an'ın doğru anlaşılması ve hakikatlarının yaşanması için çalışmış, bu uğurda her türlü sıkıntı ve meşakkate razı olmuştur. Onun yazdığı eserler Kur'an'ın bir çeşit tefsiri niteliğindedir. Kur'an'ın mucizelik yönlerinden en parlağının belagat olduğunu göstermiştir. O, Kur'an'ın işaretiyle ahir zamanda bütün insanlığın ilim ve fenne yöneleceğini, ilim ve fennin de en parlağı olan belagat ve cezaletin, insanlar arasında çok rağbet göreceğini söylemiştir. Belagat, hitap ettiği kimselere göre uygun ve tam yerinde düzgün ve hakikatlı söz söyleme sanatıdır. Bediüzzaman Said Nursi, hayatı, yüksek gayeleri, manevî şahsiyeti, düşünceleri fedakarlıkları ve telif ettiği Nur Risâleleri ile insanlığa her zaman güzel bir örnek olmuştur. İşte böyle bir zatın eserlerinin incelenmesi ile meydana gelen bu tezimizde Bediüzzaman Said Nursi'nin Kur'an'ın belagatı ile alakadar kullandığı kavramların tesbit edilmesi ve bu kavramların izah edilmesi ve misallerle açıklanmasına çalıştık. Bunlarla beraber Said Nursi'nin beliğ kişiliği ve eserlerini tanıtmayı, tezimizin amacına ulaşması yönünden gerekli gördük.Anahtar Kelimeler: Bediüzzaman, Kur'an, belagat, camiiyet Bediüzzaman Said Nursi is a man who spent his life in the way of employment for Quran. During his life, he worked in order to be understood the Quran correctly and lived the truths of Quran, and he consented for every trouble and fatigue for this purpose. The works which he wrote is a kind of commentary of Quran. He showed that eloquence is the most brilliant miraculous characteristic of Quran. All humankind will head towards science and technology and eloquence which is the most brilliant in science and technology will be popular among the people in the latest time, he said with the signs of Quran. Eloquence is a speech art which is suitable, correct, regular and soothfast according to the collocutors.With his life, superior desire, spiritual identity, thoughts and published Nur collection, he was a good model for all humanbeings. In this thesis being outcome of analyzing his books, we have tried to detect the concepts related to his using on beliefs about quran and explain them with the examples. We consider introduction of his books and their unique identity as necessary in behalf of that thesis reach our main target.Key Words: Bediüzzaman-Koran-rhetoric- community 75

Cerrahi - Abstract
Background/Aims: In our study, we aimed to assess the effect of vitamin E and C supplementation to triple and quadruple Helicobacter pylori eradication regimens. Materials and Methods: Four hundred patients with H. pylori infection were classified into four groups. Patients in group A (n=100) received amoxicillin, clarithromycin, and lansoprazole for 2 weeks. In group B, patients (n=100) received vitamins C and E for a month, in addition to amoxicillin, clarithromycin, and lansoprazole for 2 weeks. Patients in group C (n=100) received amoxicillin, clarithromycin, lansoprazole, and bismuth subcitrate for 2 weeks, whereas those in group D (n=100) received vitamins C and E for a month, in addition to amoxicillin, clarithromycin, lansoprazole, and bismuth subcitrate for 2 weeks. H. pylori eradication was assessed with the C14 urea breath test 2 months after the end of the therapy. The eradication rate was assessed using per-protocol (PP) and intention-to-treat (ITT) analyses. Results: Three hundred forty-eight patients finished the study. The eradication of H. pylori was achieved in 63 of 84 patients (75%) by PP and 63 of 100 (63%) by ITT analysis in group A, 60 of 84 (71.4%) by PP and 60 of 100 (60%) by ITT analysis in group B, 72 of 89 (80.9 %) by PP and 72 of 100 (72%) by ITT analysis in group C, and 76 of 91 (83.5%) by PP and 76 of 100 (76%) by ITT analysis in group D. There was no remarkable change between groups A and B (p>0.05). Similar results were also found between groups D and C (p>0.05).Conclusion: This study revealed that supplementing vitamins C and E to either the triple or quadruple therapies did not provide an additional advantage for achieving significantly higher eradication rates for H. pylori

Escherichia coli, üriner sistem inf eksiyonlarından (ÜSİ) en sık izole edilen mikroorganizmadır. Son zamanlarda ülke- mizde üropatojen E.coli suşlarında, ÜSİ tedavisinde sık kullanılan antibiyotiklere karşı duyarlılıkta azalma görülmektedir. Bu çalışmada, ÜSİ ön tanısıyla üroloji polikliniğinden gönderilen idrar kültürlerinden izole edilen E.coli suşlarının siprof loksa- sin, nitrof urantoin ve f osf omisin duyarlılıkları, Clinical and Laboratory Standards Institute (CLSI) önerileri doğrultusunda disk dif üzyon yöntemi ile belirlenmiş; genişlemiş spektrumlu beta-laktamaz (ESBL) üretimi çif t disk sinerji yöntemiyle araş- tırılmıştır. İncelenen E.coli izolatlarında en yüksek direnç oranı % 32.1 ile siprof loksasine karşı saptanmış, bunu % 5.1 ile nitrof urantoin ve % 4.5 ile f osf omisin takip etmiştir. ESBL pozitif lik oranı % 22.5 olarak tespit edilmiştir. Direnç oranları ESBL pozitif ve negatif lerde sırasıyla siprof loksasine karşı % 85.3 ve % 17.3 nitrof urantoine karşı % 12.6 ve % 2.9, f osf omi- sine karşı ise % 13.9 ve % 1.9 olarak saptanmıştır. Bölgemizde siprof loksasine direnç oranında yükselme gözlenmesine karşın f osf omisin ve nitrof urantoin, ÜSİ tedavisinde iyi birer alternatif olmayı sürdürmektedir. Escherichia coli is the most commonly isolated microorganism in cases of urinary tract inf ection (UTI). Currently, in our country, susceptibility of uropathogenic E.coli strains to commonly used antibiotics in the treatment of UTIs has decrea- sed. In this study, the resistance rates of E.coli strains isolated f rom urine samples of patients with UTI f rom urology outpa- tient clinic were determined f or ciprof loxacin, nitrof urantoin and f osf omycin by disk diff usion method according to Clinical and Laboratory Standards Institute (CLSI) guidelines and extended-spectrum beta-lactamase (ESBL) production was tested by double-disk synergy method. In E.coli strains the highest resistance rate was f ound f or ciprof loxacin (32.1 %). This was f ollowed by nitrof urantoin (5.1 %) and f osf omycin (4.5 %). ESBL positivity rate was f ound as 22.5 %. Resistance rates f or ESBL positive and negative cultures were determined as, 85.3 % and 17.3 % f or ciprof loxacin, 12.6 % and 2.9% f or nitrof u- rantoin, 13.9 % and 1.9 % f or f osf omycin. Despite the increased resistance observed f or ciprof loxacin in our region, f osf omycin and nitrof urantoin continue to be a good alternative in the treatment of UTIs.

`Disharmoni` ve `dissonanz` sözcükleriyle de ifade edilen antagonizm kavramı, düşünce tarihinde insanı diğer canlılardan ayıran en büyük güçlerden biri olarak ele alınmıştır. Var olduğu ilk günden bu yana bilim, sanat, teknoloji, tıp, felsefe, edebiyat gibi birçok alanda sayısız başarıya imza atan insan tüm kazanımlarını, çekirdeğinde saklı olan `antagonizm` e borçludur. Antagonist davranışları sayesinde olanaklar varlığına dönüşen insan, bir yandan akıl varlığı; diğer yandan doğa varlığı olması nedeniyle kendisinden ve kendi durumundan hiçbir zaman hoşnut olmamış, uyumsuz olma durumunu daima muhafaza etmiştir. Sevgi, nefret, bilgi, doğruluk, yalancılık, masumluk, saflık, dürüstlük, dostluk, hak, adalet, güven, güvensizlik, inanma söz verme, saygı, şeref, iyi - kötü gibi yüksek değerler; yarar, kuşku, çekememezlik, kıskançlık, haksızlık gibi ilgi ve çıkarın ortaya koyduğu araç değerler ile gelenekler, görgü kuralları, moda, zevk gibi kaynağında alışkanlıkların yer aldığı sosyal değerlerle kuşatılmış olan insan, kendisiyle ve toplumla her an çatışma halinde olmuştur. Bu çatışma, kendine özgü kuralları ve gerçekliği olan roman şahıslarının davranışlarına da yansımıştır. Bu tezde önce yapılan Felsefî araştırmalar ışığında antagonizm kavramı hakkında bilgi verilmiş; sonra da Türk romanının en önemli isimlerinden Halit Ziya Uşaklıgil'in mevcut sekiz romanındaki şahısların davranışları bu bağlamda incelenmeye çalışılmıştır. ANAHTAR SÖZCÜKLER: İnsan, antagonizm, uzlaşmaz karşıtlık, Halit Ziya Uşaklıgil romanları Antagonism, also expressed as disharmony and dissonance has been taken up as one of the most powerful features that distinguishes man from other creatures in the history of thought.Since its existence science, art, technology, medicine, philosophy, literatüre and in other countless fielsds human being owes all the acquisition to antagonism.Human being that turns into ceature of possibilities by means of antagonist behaviours, has never been satisified wit himself and his condition because of being creature of wisdom and natüre and also preserved his state of being misfit. Human being has conflicted with both himself and society when surrounded by high values such as love, hate, wisdom, honesty, lying, innocence, purity, friendship, justice, lack of confidence, trust, respect, honour, good-evil; features of self interest such as suspicion, envy, jealousy, injustice, social values such as traditions, manners, social etiquettes, fashion and pleasure. This conflict reflects heroes' and heroines' behaviours peculiar to its rules and reality.According to the philosophical researhes firstly antagonism has been defined then in Halit Ziya Uşaklıgil's ,one of best authors ever, novels heroes and heroines' behaviours have been studied within the context.KEY WORDS: Human Being, Antagonism, Intranssigence opposition, novels of Halit Ziya Uşaklıgil. 245

Amaç Çalışmamız soliter böbrek ile sağlıklı iki böbreğe sahip bireylerde böbrek boyut ölçümleri ve stereolojik yöntemle böbrek hacim hesaplamasının yapılması ve iki grup arasındaki morfolojik farklılıkların belirlenmesi amaçlandı. Materyal ve Metot Herhangi bir şikayet ile Namık Kemal Üniversitesi Araştırma ve Uygulama Merkezine başvurup, kontrast madde verilerek abdominal bilgisayarlı tomografisi (BT) çekilen hastalar çalışmaya dahil edildi. Hacim ölçümleri BT görüntüleri üzerinde Cavalieri prensibi ile yapıldı. Bulgular Çalışmamıza katılan bireylerin 22’si soliter böbrek, 30’u sağlıklı iki böbreğe sahiptir. Normal grup için böbrek hacim ortalaması 159 cm3, böbrek uzunluğu 10.7 cm, genişliği 6.6 cm ve kalınlığı 5 cm olarak bulundu. Soliter böbrek grubunda ise, böbrek hacmi 274 cm3, uzunluğu 12 cm, genişliği 7 cm ve kalınlığı 6 cm bulundu. Sonuç Soliter böbrek, normal böbreğe göre daha uzun, daha geniş, daha kalın ve hacimsel olarak da daha büyük olma eğilimindedir. Çalışmamızda soliter böbrek ile sağlıklı iki böbreğe sahip bireyler arasında, böbrek boyut ve hacim ölçümleri ile ilgili morfolojik farklılıklar ortaya konulmuştur. Elde edilen bu bulgular bazı böbrek hastalıklarının klinik tanı ve tedavisinde böbrek boyut ve hacminin doğru olarak değerlendirilmesi açısından literatüre katkıda bulunacağı düşüncesindeyiz. Aim This study was undertaken to compare the morphological differences between individuals with one functioning kidney and individuals with two functioning kidneys through the measurement of dimensions and stereological renal volume estimations. Materials and Methods The target sample consisted of patients who underwent an abdominal CT examination after attending Namık Kemal University’s Clinical Research and Application Center seeking medical attention. The volumetric estimations of CT images were based on the Cavalieri Principle. Results Of the overall study population, 22 had one healthy kidney and 30 had two healthy kidneys. Average renal dimensions were volume 159 cm3, length 10.7 cm, width 6.6 cm, and thickness 5 cm among anatomically normal individuals. The corresponding figures in the sole-functioning kidney group were volume 274 cm3, length 12 cm, width 7 cm, and thickness 6 cm. Conclusion Sole-functioning kidneys were longer, thicker, wider, and more voluminous compared with normal kidneys. We believe that the morphological differences between solitary and normal kidneys observed in this study in terms of dimensions and volume may represent a contribution to the existing literature that may assist in accurate volume and dimension estimations for clinical diagnosis and treatment of renal conditions.

The purpose of this study was to evaluate the efficiency of uterine myoma embolization in our institution. Myomas are the most common gynaecological problem experienced by women, in 20–40% of women of childbearing age. Symptomatic myomas can cause a diversity of symptoms, which can be divided into four categories: bleeding symptoms (irregular and/or heavy menstrual bleeding), pain, bulk-related symptoms and subfertility. Traditionally, symptomatic myomas have been treated with myomectomy or hysterectomy. UME has been re-ported to be an effective and safe alternative to treat myomas UME is a percutaneous transcatheter embolisation technique using embolisa-tion material to occlude the (end-) arteries supplying the myoma. UME blocks off the blood supply to myomas, causing them to shrink. UME should be the preferred treatment option for the fertil patients to whom hysterectomy is offered or hysterectomy need is predicted during myomectomy., Bu çalışmanın amacı ünitemizde yapılmış olan UME işlemlerinin etkinliğini değerlendirmektir. Myomlar, doğurganlık çağındaki kadınla-rın %20-40 etkileyen, en yaygın jinekolojik hastalıktır. Semptomatik myomları oluşturduğu şikayetler, kanama (düzensiz ve/veya fazla adet kanaması), ağrı, kitle etkisine bağlı bulgular ve infertilite başlıklarında 4 gruba ayrılabilir. Geleneksel olarak semptomatik myomlar myo-mektomi veya histerektomi ile tedavi edilir. Literatürde UME nin myomların tedavisinde etkili ve güvenli bir alternatif olduğunu belirtilmek-tedir. UME myomu besleyen uç arterin embolizan materyel kullanılarak tıkandığı perkutan transkatater embolizasyon işlemidir. UME, besleyici damarın kan akımını keserek myomun küçülmesini sağlar. Histerektomi önerilen veya myomektomi sırasında histerektomi gereke-bileceği ön görülen ve doğum beklentisi olan hastalarda UME nin tercih edilmesi gereken tedavi yöntemi olduğunu düşünüyoruz.

Tez (Yüksek Lisans) -- İstanbul Teknik Üniversitesi, Fen Bilimleri Enstitüsü, 2010, Thesis (M.Sc.) -- İstanbul Technical University, Institute of Science and Technology, 2010, GEMİDE ÇALIŞMA KOŞULLARININ GEMİ ADAMLARI ÜZERİNDEKİ OLUMSUZ ETKİLERİ ÖZET Çalışma şartlarından doğan bir sendrom olan Tükenmişlik, kişilerin mesleğin özgün anlamı ve amacından kopması, hizmet verdiği insanlarla ilgilenemiyor oluşu yada aşırı stres ve mesleki doyumsuzluğa tepki olarak kişinin kendini işinden geri çekmesidir. Bu çalışmanın amacı Türk bayraklı ticari gemilerde çalışan farklı görevlerdeki gemiadamlarının tükenmişlik düzeylerini belirlemek; ayrıca, tükenmişlik durumlarının gemiadamlarının yaşlarına, denizde çalışma sürelerine ve gemideki görevlerine göre farklılıklarını ortaya koymaktır. Araştırmanın örneklem hacmini Türk ticaret gemilerinde çalışan 4’ü “Kaptan”, 8’i “Güverte Zabiti”, 8’i “Makine Zabiti”, 15’i “Güverte Personeli”, 8’i “Makine Personeli” olarak 43 Gemiadamı oluşturur. Çalışmada Maslach Tükenmişlik Envanteri’nden esinlenerek geliştirilmiş 23 maddelik Gemiadamı Tükenmişlik Anketi (GTA) kullanılmıştır. Ankette gemiadamlarının tükenmişlik durumu ‘Duygusal Tükenme (9 madde), Duyarsızlaşma (5 madde) ve Kişisel Başarı (9 madde) olmak üzere toplam üç alt ölçekte değerlendirilmiştir. Verilerin analizinde, SPSS 16.0 paket programı (Sosyal Bilimler için İstatistik Paket Programı) kullanılmıştır. Kullanılan verilere öncelikle Güvenilirlik Analizi uygulanmış, sonra Kolmogorov-Smirnov Normallik Testi, gemiadamlarının demografik özelliklerine göre farklılık analizleri, non-parametrik testlerden Ki-Kare analizi ve tükenmişlik alt boyutları arasında Korelasyon (ilişki) analizi yapılmıştır. Çalışmanın sonucunda; gemiadamlarının Duygusal Tükenmişlik alt boyutunda tükenmişlik yaşamadığı, buna karşın Duyarsızlaşma ve kişisel başarı alt boyutlarında ileri düzeyde tükenmişlik yaşadıkları belirlenmiştir. Ayrıca tükenmişlik alt boyutlarının Gemiadamları’nın yaş, denizde çalışma süreleri ve gemideki görevlerine göre anlamlı bir farklılık göstermediği de tespit edilmiştir. Bu durumun, gemiadamı sayısının yetersizliği, uzun çalışma saatleri, düşük kalitede uyku, beslenme yetersizlikleri, elektromanyetik kirlilik, gürültü ve olumsuz çevre koşullarından kaynaklandığı düşünülmektedir., THE NEGATIVE EFFECTS OF WORKING CONDITIONS UPON SEAMEN ON SHIPS SUMMARY Burnout can be defined as: individuals’ breaking from the very meaning and aim of their profession, their not being able to be concerned with the people they are serving or their withdrawing themselves from the job in reaction to their professional insatisfaction. The aim of this study is to determine the burnout levels of seamen of different status on commercial ships under Turkish flag. Besides, this study aims to discover the burnout level differences of seamen according to their age, the period they spent on sea, and their duty on the ship. The illustration number of this study consists of 43 seamen; 4 of them are ‘Captain’, 8 of them are ‘Deck Officer’, 8 of them are ‘Engine Officer’, 15 of them are ‘Deck Staff’, 8 of them are ‘Engine Staff’. In this study, Seamen Burnout Questionnaire (GTA), a questionnaire developed on Maslach Burnout Questionnaire, is used. In this questionnaire, burnout levels of seamen are analyzed under three sub-classes: ‘Emotional Exhaustion’(9 Items), ‘Depersonalization’(5 Items) and ‘Individual Success’(9 Items). Analyzing the data, SPSS 16.0 packet program (A statistical packet program for social sciences) is used. The mentioned data has undergone respectively, a Reliability Analysis, Kolmogorov-Smirov Normality Test, Difference Analyses according to seamen’s demographic characteristics, Ki-Kare analysis from non-parametric tests and Correlation Analysis among burnout sub-classes. As a result of this study, it was determined that seamen do not suffer from burnout in the sub-level of Emotional Exhaustion, but suffer from great levels of burnout in the sub-levels of Depersonalization and Individual Success. Furthermore, it was discovered that sub-levels of burnout do not differ very much according to age, the period they worked on sea and their duty on ship. It is thought that, this situation is a result of few number of seamen, long working periods, low quality sleep, malnutrition, electromagnetic pollution, noise and negative environmental conditions., Yüksek Lisans, M.Sc.

Katma değerli yeni servislerin sayısının artması ile beraber konuma dayalı servislerin önemi artmaktadır.Acil aramaların nereden yapıldığının belirli bir hata payı içinde tespit edilmesini şart koşan Uluslararası İletişim Komisyonu da konuma dayalı servisler üzerinde anahtar bir etken olmuştur. Bu nedenle konum belirleme anahtar bir araştırma sorunu olmuş ve birçok sayıda konum belirleme çözümü sunulmuştur.Bu çözümlerden bazıları hücre numarası, varış zamanı ve açısı, istatistiksel ve parmak izi yöntemleridir. Bu tez parmak izi yöntemine dayalı bir konum belirleme yöntemi öne sürmektedir.Parmak izine bağlı konum belirleme bir kullanıcının yerini bulabilmek için daha önce toplanmış sinyal ölçümlerinden yararlanır. Önceki sinyal ölçümleri sonradan sinyal izi eşleştirmede kullanılmak için bir veritabanına kaydedilir ve bu veritabanına sinyal izi veritabanı denir. Sinyal izine bağlı konumlandırma dört aşamadan oluşmaktadır, bunlar ölçüm toplama, sinyal izi filtreleme, sinyal izi eşleştirme ve konum hesaplamadır.Bu tezde konuma dayalı servislerin hassaslığını artırmak için yeni bir sinyal izi eşleştirme yöntemi önerilmektedir. Bu yeni yöntem en çok bilinen ve en çok kullanılan yöntemler ile kıyaslanmıştır ve performansı bu algoritmalar ile karşılaştırılmıştır. Önerdiğimiz yöntem hücresel ağda veya cep telefonlarında fazladan bir donanım yada yazılıma ihtiyaç duymadan çalışabilmektedir. Sistem mobil kullanıcının sinyal değerlerini ve hücresel ağ tarafından yapılan ölçümleri kullanarak kullanıcının yerini tespit edebilmektedir. Bu tezde önerilen yöntemin karşılaştırılan yöntemlerden konum hassasiyeti açısından daha iyi sonuçlar verdiği gösterilmiştir. Location based services have attracted too much attention recently due to the increasing number of new value-added services. Also, the requirement set by Federal Communications Commission (FCC) to locate emergency calls according to certain accuracy criteria has been the key factor for the development of location methods. Hence, location positioning has been a key research problem and numerous localization solutions have been proposed. These include technologies such as Cell ID, angle and time of arrival methods, statistical methods and fingerprinting methods. This paper proposes a fingerprinting based positioning method.Location fingerprinting is a novel method that benefits from the previous signal measurements to find the location of a user. The previous signal measurements are stored into a database, called fingerprint database, to be used for fingerprint matching. Fingerprinting consists of four phases such as data collection, fingerprint filtering, fingerprint matching, and location estimation algorithms.In this thesis, a new fingerprint matching algorithm is proposed to increase the accuracy of the location based services. This new fingerprint matching algorithm is compared with the most frequently used and well-known algorithms. The proposed algorithm does not require any hardware modifications. It does not require any modifications in the software on the mobile devices, either. By exploiting the measurements that are already being performed by the cellular network, the system can estimate the location of the mobile station using the RSS values of the MS. It is shown that the proposed algorithm gives better results than the compared algorithms in terms of accuracy. 76

AMAÇ: Sıçanlarda testis torsiyon süresine bağlı olarak Leydig hücrelerinin endokrin fonksiyonları hakkında veri elde edebilmek için, hipotalamo-hipofizer-gonadal aks hormonlarının düzeylerindeki değişiklikleri erken ve geç dönemde tespit etmeyi amaçladık.MATERYAL, METHOD: Sprague-Dawley soyu yetişkin erkek sıçanlar Cerrahpaşa Deney Hayvanları Üretim ve Bakım Laboratuarından elde edildi. Sıçanlar, her grupta 10 tane sıçan olmak üzere 4 gruba ayrıldı, 1. grup sham grubu idi. Anestezi altında bütün gruplardaki sıçanların batınları açıldı ve sol testislerine orşiektomi yapıldı. Sıçanların sağ testisleri sırasıyla 2. grupta 1 saat, 3. grupta 3 saat, 4.grupta 5 saat süreyle 7200 torsiyone edilip, daha sonra sıçanların sağ testisleri detorsiyone edildi. Birinci gruptaki sıçanların sağ testislerine herhangi bir işlem uygulanmadı. Bütün sıçanlardan torsiyon-detorsiyonun 3. ve 30. gününde kuyruk veninden 2 cc kan alınarak serum total testosteron, serbest testosteron, LH düzeyleri ELİSA yöntemiyle ölçüldü.BULGULAR: Tüm gruplardaki hayvanların hormon tetkikleri değerlendirildiğinde 30. gündeki total testosteron düzeylerinde sadece 1. grup (sham) ile 4. grup arasında istatistiksel anlamlı fark bulundu. Dördüncü grup ile diğer bütün gruplar 30.gün serbest testosteron düzeyi arasında istatistiksel anlamlı fark bulundu. Dördüncü grup ile 1. ve 2. grup 30. gün LH düzeyleri arasında bulunan istatistiksel anlamlı fark, total testosteron ve serbest testosteronda bulunan farklarla uyumlu olup, 5 saatlik torsiyon sonrası testisin testosteron üretimininde bozulma olduğunu destekliyordu.SONUÇ: Beş saatlik torsiyon uygulanan sıçanlarda 30. günde bakılan total ve serbest testosteron düzeyinin diğer gruplara göre anlamlı derecede düşük çıkması, sıçanlarda 5 saatlik torsiyondan sonra Leydig hücrelerinin fonksiyonunun bozulduğunu gösterdi. PURPOSE: We aimed to investigate the alterations in the hypotalamo-hypofiser-gonadal hormones? levels; to find out the endocrin functions of Leydig cells due to duration of testicular torsionMATERIAL, METHOD: Sprague Dawley adult male rats were obtained from Experimental Animal Labratory of Cerrahpasa School Of Medicine. Rats were classified in 4 groups containing 10 each. Orchiectomy was performed in left testicles under anesthesia in all groups. At right testicles, torsion and later detorsion was carried out for 1 hours in 2. group, 3 hours in 3. group, and 5 hours in 4. group, respectively. In 1. group (sham), any intervention was carried out in right testicles. At the 3th and 30th day after torsion-detorsion 2 cc venous blood was obtained and levels of LH, total and free testosterone were measured with ELISA.RESULTS: Significant statistical relation was found at total testosterone levels at 30th day between sham and 4. groups. Also, significant relation was found at free testosterone levels at 30th day between 4th group and other groups. The statistical significant relation at the levels of LH at 30th day between 4th and first and second groups was in harmony with the difference at total and free testoterone and supports the deterioration at the testosterone production of testis after a duration of 5 hour testicular torsion .CONCLUSION: Total and free testosterone at 30. day in the 4.group, was torsioned 5 hours, was found significantly low according to other groups. We demonstrate, Leydig cells continue endocrin functions until 5 hours torsion at rats. 45

Objective: To investigate the effect of biofeedback therapy on children with desmopressin-resistant primary monosymptomatic enuresis (MsE). Material and methods: The study comprised both retrospective and prospective sections. A total of 262 medical files of patients who were diagnosed as enuresis between November 2012 and January 2015 were retrospectively screened. Patients with neuropathic bladder, daytime voiding problems, anatomical pathology and enuresis-related diseases were excluded from the study. The demographic data and family characteristics of 29 children with desmopressin-resistantprimary MsE were recorded. After biofeedback treatment patients whose frequency of enuretic episodes decrease by more than 50% were included in the successful biofeedback treatment group (SBTG), while other patients were categorized in the unsuccessful biofeedback treatment group (USGBT). The outcomes of uroflowmetry, voided volume, postvoiding residue (PVR) and total bladder volume/age-adjusted normal bladder capacity (TBV/NBC) were recorded before and at the sixth month of the treatment. Results: The mean age of 29 patients included in the study was 9.14±3.07 (6-15) years. Of patients, 16 were male (55.2%) and 13 were female (44.8%). Before biofeedback treatment the frequency of enuresis was 25.1±5.76 days/month, while after treatment this was calculated as 8.52±10.07 days/month. After treatment 8 patients (28.6%) achieved complete dryness. Twenty patients (69%), benefited from biofeedback (SBTG), while there were 9 patients (31%) in the USBTG group. There was no significant difference between the SBTG and USBTG groups in terms of age, body mass index and sex. The average bladder capacity of the patients increased from 215 mL to 257 mL after biofeedback treatment (p<0.001). The TBV/NBC value before treatment was 0.66, while after treatment it was 0.77 (p<0.001). There was a statistically significant difference between the SBTG and USBTG groups in terms of presence of MsE in mother, and both parents (p=0.001, p=0.016, respectively). Conclusion: Biofeedback therapy is a safe, simple, and minimally invasive treatment modality in children with MsE resistant to desmopressin treatment. This treatment, which was found to increase total bladder capacity, may be recommended for children with MsE when conventional desmopressin treatment fails. [ABSTRACT FROM AUTHOR]

CARBON dioxide in the blood ,BICARBONATE ions ,BLOOD pH ,BLOOD gases analysis ,ACID-base imbalances ,ARTERIAL puncture ,THROMBOSIS - Abstract
Blood gas analyses are needed to reveal any kind of acid-base imbalance in some patients. Traditionally, arterial punctures are performed to obtain the blood samples for blood gas analyses. Arterial puncture is not a completely safe procedure. It may cause serious problems including arterial thrombosis, arteriovenous fistula, pseudoaneurysms and hematoma. In this retrospective reviewing, it was aimed to yield novel formulations to predict the blood pH only from CtCO
2 and HCO3 values which can easily be measured in venous blood samples obtained for other diagnostic and follow-up purposes. [ABSTRACT FROM AUTHOR]- Published
