Determination of Sweetgum (Liquidambar orientalis Miller) Populations Distribution with Geographic Information Systems and evaluation of Landscape Metrics by using Habitat Quality Assessment; A case study of Mugla Koycegiz

Bu çalışmada, Köyceğiz-Dalyan Havzası'nda yayılış gösteren Sığla Ağacı (Liquidambar orientalis) popülasyonlarının coğrafi bilgi sistemleri yardımıyla belirlenmesi, peyzaj metrikleri kullanılarak bulunduğu matris içinde değerlendirilmesi ve koruma-kullanma önerilerinin geliştirilmesi amaçlanmıştır. Çalışma; araziye ilişkin veri toplama, verilerin sayısallaştırılarak bilgisayar ortamında depolanması, peyzaj yapısının çeşitli peyzaj metrikleri kullanılarak analiz edilmesi, koruma önerilerinin geliştirilmesi şeklinde 4 aşamada yürütülmüştür. Veri toplama aşamasında bölgenin 1/25000 ölçekli topoğrafik haritalar, Landsat 7 ETM+ uydu görüntüleri ve ortofoto haritalardan yararlanılmıştır. Araştırma sonucunda ulusal ve uluslararası düzeyde önem taşıyan ve endemik bir tür olan Anadolu Sığla Ağacının (Liquidambar orientalis Miller), Köyceğiz-Dalyan Havzasındaki doğal yayılış alanı ve peyzaj yapısı belirlenmiştir. Özellikle tarım ve yerleşim alanlarının sığla ormanları üzerine baskısı olduğu ve bu ormanların tehlike altında olduğu görülmüştür. Bu kapsamda sığla ormanlarının bütünlüğünü korumak ve çevresel baskılara dayanımını artırmak üzere, orman içinde bozunuma uğramış yerlerin yeniden aynı tür ile ağaçlandırılması gerektiği ve ormanları çevreleyen 50 m ile 250 m arasında tampon bölgelerin oluşturularak kenar etkilerinin azaltılması gerektiği sonucuna ulaşılmıştır.The purpose of this study is to determine the distribution of the sweetgum trees’ (Liquidambar orientalis Miller) populations with geographic information systems, and to evaluate and propose protection-use development proposals by using the landscape metrics in the Koycegiz-Dalyan River Basin. The study has been carried out in four stages as data collection of land surface, data to be digitized and stored in the computer, landscape structure analysis by using landscape metrics and development of protective proposals and recommendations. During data collection, 1/25000 scale topographic maps of the basin, orthophoto aerial photograps and Landsat 7 ETM + satellite images were utilized. As a result, the natural distribution area of Anatolian Sweetgum tree (Liquidambar orientalis M.), which is endemic and important in national and international level, has been determined in the Koycegiz-Dalyan Basin. Especially, the agricultural and residential factors have increased the threat for the sweetgum forest. In this context, the a forestation should be done with the same kind of trees in degraded forest areas in order to protect the integrity of the forest and to increase resistance to environmental pressures, and forest edge effects should be reduced by creating surrounding between 50 meters and 200 meters buffer zones

Early penile metastasis from primary bladder cancer as the first systemic manifestation: a case report

Metastatic involement of penis is an exceptionally rare condition. 77% of the metastases are originated from the pelvic region; prostate and bladder are the most frequent primary locations. Retrograde venous route, retrograde lymphatic route, arterial spread, direct extension, implantation and secondary to instrumentation are the mechanisms of metastasis. Approximately two thirds of all penile metastasis are detected at a mean time of 18 months after the detection of the primary tumor and the remaining one third is presented at the same time with primary tumor. Diagnosis is usually made by biopsy and also non invasive methods as MRI or colour-coded duplex ultrasonography. Treatment options in these patients are local excision, partial or complete penectomy, external beam radiation therapy and chemotheraphy. Despite these alternatives prognosis is usually poor

Usefulness of Serum D-Dimer Level in Acute Renal Infarction

Acute renal infarction (ARI) is a rarely encountered disease in emergency services, but is of particular importance owing to higher mortality and morbidity rates in the absence of early diagnosis and intervention. On the other hand, urolithiasis cases are admitted to emergency departments very frequently with the complaint of pain. ARI with non-specific symptoms or urolithiasis-like pain would increase the likelihood of being omitted in crowded emergency rooms. Previous studies reported supportive diagnostic role in ARI of increased serum lactate dehydrogenase and C-reactive protein levels and white blood cell count in the presence of hematuria; however, none mentioned D-dimer as a likely diagnostic or prognostic marker. We hereby present 2 case reports where a contrast-enhanced tomographic scan performed on the basis of suspicions raised by high serum D-dimer levels which established the definitive diagnosis ARI. Our aim was to emphasize that serum D-dimer may be used as a criterion for supporting or excluding the thromboembolic events, such as renal and mesenteric infarction

1995-2019 Yılları Arasında Türkiye’nin Yolsuzluk Düzeyi ile Kurumlar Vergisi Arasındaki İlişki

Kurumlar vergisi, tüzel kişilerden ve sermaye şirketlerinin kurum kazançları üzerinden alınan bir vergidir. Kurumlar vergisinin başlangıcı 1909 yılı olmasına rağmen özellikle Birinci Dünya Savaşı sonrasında bu vergi önem kazanmıştır. Uluslararası Şeffaflık Örgütü, ülkelerin kamu kesiminde algılanan yolsuzluğu 1995 yılından itibaren anketler yardımıyla ölçmekte ve yolsuzluk algılama endeksi olarak yıllık bazda yayınlamaktadır. Endeks ülkelerdeki yoksulluk seviyelerini 2012 yılına kadar 0-10 arasında, 2012 yılı sonrasında ise 0-100 arasında değerlendirmektedir. Ülkelerdeki endeks değerlerinin sıfıra yaklaşması yolsuzluğun arttığı anlamına gelmektedir. Çalışmamızda, Türkiye’nin 1995-2019 yılları arasındaki kurumlar vergisi oranları, kurumlar vergisi gelirleri, kurumlar vergisi gelirlerinin GSYH içindeki payı ile yolsuzluk algılama endeksi arasındaki ilişki, yıllık veriler kullanılarak granger nedensellik analizi yardımıyla analiz edilmiştir. Ülkemizdeki kurumlar vergisi oranları referans yılları içinde değişiklik göstermesi nedeniyle kurumlar vergisi gelirlerinde ve kurumlar vergisi gelirlerinin GSYH içindeki payında değişikliğe neden olmaktadır. Vergi oranlarındaki değişikliğin bu olumsuz etkisini ortadan kaldırmak amacıyla referans yıllardaki vergi oranlarının ortalaması alınarak kurumlar vergisi gelirleri ve gelirlerin GSYH içindeki payı yeniden hesaplanarak analize dahil edilmiştir. Sonuç olarak, değişkenler arasında ilişki olmadığı tespit edilmiştir

Asymmetrical Bilateral Traumatic Hip Dislocation with Segmental Femur Fracture

Introduction: Hip dislocations are extremely rare, but they are orthopedic emergencies that need to be immediately intervened. Traumatic hip dislocations are usually unilateral and occur toward the posterior region. Bilateral traumatic hip dislocations, on the other hand, are rarer. Asymmetric occurrence of bilateral traumatic hip dislocations is even rarer. The possibility of spontaneous hip dislocation in a healthy person is very unlikely. This is because ligaments wrapping the hip joint make it quite stable. Thus, hip dislocation usually occurs due to a high-energy trauma. Case Report: In this paper we report a unique female patient with asymmetric bilateral traumatic hip dislocation accompanied by a segmental fracture of the femur due to a traffic accident. The patient's right hip was reduced under sedoanalgesia at the emergency department and the left hip was reduced under anesthesia at operating room. Avascular necrosis did not develop at her 2-year follow-up; however, she has been re-operated after developing nonunion in the left femoral segmental fracture. Conclusion: In conclusion, hip dislocations should be treated in first six hours due to the risk of avascular necrosis. Uncomplicated hip dislocations without accompanied fractures can be treated with sedoanalgesia in emergency service settings. However hip dislocations which are complicated with accompanied fractures should be reduced in operation rooms without delay

Serum SCUBE-1 levels and return of spontaneous circulation following cardiopulmonary resuscitation in adult patients

Background SCUBE 1-has been used as a biomarker for the diagnoses of myocardial infarction, stroke, mesenteric ischemia, and gastric cancer in some recent studies. In this study, we investigated the relationship between serum SCUBE-1 levels and return of spontaneous circulation (ROSC) in patients who received cardiopulmonary resuscitation (CPR). Methods Patients over 18 years of age who were not pregnant and received CPR were divided into two groups: those who achieved ROSC and those who died. There were 25 patients in each group. SCUBE-1 and other routine biochemical parameters were studied in blood samples taken at the time of admission. Results There was no significant difference between the age and gender distribution of the patients between the two groups. The SCUBE-1 value of the ROSC group was significantly higher than that of the non-survivor group ( p ˂ 0.05). At a cut-off value of 9 ng/mL, SCUBE-1 had a sensitivity of 100%, a positive predictive value of 65.8%, specificity of 48%, and a negative predictive value of 100% in predicting ROSC. Conclusions The SCUBE-1 values were found to be significantly higher in the ROSC group compared with the non-survivor group

Since she had been experienced corrosive oesophagitis during the second year of her life, her oesophagus had replaced with a colon graft on that time. Patient's deformed colony graft removed at our hospital. The imaging findings of this patient submitted

A new species of Arenosetella Wilson, 1932 from Turkey with notes on the genus (Copepoda, Harpacticoida, Ectinosomatidae)

A new species of the genus Arenosetella CB Wilson, 1932 is described from specimens that were collected from the Mediterranean coast of Turkey. The new species is closely related to A. fimbricaudata McLachlan & Moore, 1978, A. germanica Kunz, 1937 and A. kaiseri Lang, 1965 within the 21 species/subspecies of the genus by having five setae at the exopod of the first and the second swimming leg, six setae at the terminal exopod segment of the fourth swimming leg, four setae at the terminal segment of the endopod of the first to fourth swimming legs and four marginal and one surface seta at the exopod of the fifth swimming leg of female. It can be differentiated from all of the species above by the loss of the inner seta at the first segment of the exopod of the second and the third swimming legs. As the diagnosis of the genus was not up to date and did not cover all of the species, a revised and extended diagnosis is provided. The antenna of A. bassantae Mitwally and Montagna 2001 was re-examined from the holotype, as the given armature in the original description was unusual for the basic pattern of the family, an amended description and drawing are presented herein
