    Uslular and Gençalioglu-Kuscu [2018] have written a lengthy, and highly critical, comment about McNab et al. [2018] which states that our data compilation for Neogene (and Quaternary) volcanic rocks from Anatolia is selective, inconsistent, and not fit for purpose. We state for the record that our compilation is not based on analyses from the published GEOROC database. Uslular and Gençalioglu-Kuscu [2018] also state that our sub-division of this database into three broad longitudinal categories is unrealistic since it does not consider the full range of different tectonic units. They conclude that our interpretation of the link between Neogene-Quaternary volcanism and uplift of Anatolia is erroneous. We refute this rather strongly worded comment by carefully addressing the five substantive issues raised

    The Central Anatolian Volcanic Province (CAVP, Türkiye), situated in a post-collisional setting, encompasses widespread polygenetic and monogenetic volcanism since the mid-to-late Miocene. Monogenetic volcanoes are clustered in six distinct volcanic regions across the CAVP, displaying well-exposed deposits and including many proxies for understanding the volcanological, petrological, and even paleoenvironmental evolution of the region. Maars are the lesser-known edifices among these volcanoes, and their presence has been mostly hidden in the local maps and reports, except for a few studies published in international journals. However, maars in the CAVP are prone to provide many insights into many questions raised in the recent advancement of maar literature globally. In addition, the potential hazard assessment of volcanically and tectonically active CAVP certainly needs further detailed information from these small-volume products of phreatomagmatic eruptions. This thesis employs a comprehensive and integrated approach in three main chapters (Chapters 2-4), preceded by a general introduction (Chapter 1) and followed by a concluding synthesis (Chapter 5), incorporating field- and UAV-based mapping, morphometry, grain-size distribution, componentry, geoelectrical imaging, petrography and geochemistry (whole-rock, glass, and mineral) to address significant questions in the maar literature, such as the discernible correlations between magma composition and substrate geology with respect to maar morphology, the role of optimal scaled depth (OSD), and fragmentation processes in maars, as well as many other local questions raised in the CAVP literature. Furthermore, the thesis investigates the differences between felsic and mafic maars, highlighting the importance of explosion depth, vent migration, and hydrogeological conditions in their formation. The systematic survey of maar volcanism within the CAVP introduces 18 well-exposed maars and a few explosion craters to the literature with their detailed maps, well-defined representative stratigraphies, and compositions, as well as further details on their eruption dynamics integrated with the global data (Chapter 2). In-situ comparison of mafic and felsic maars within the Acıgöl caldera incorporated with extensive field observations and integrative laboratory analyses shed new light on the main relation between these compositionally distinct but mutually common volcanoes (Chapter 3). The complex behaviour of monogenetic clusters is one of the best representative features of the CAVP, and the Karapınar Monogenetic Field provides an excellent opportunity not only to examine these phenomena but also to decipher the crustal and mantle processes in the evolution of Plio-Quaternary basaltic volcanism across the CAVP (Chapter 4). </p

    Meme kanseri sonucu mastektomi yapılan hastalarda her geçen gün meme rekonstrüksiyonuna talep artmaktadır.Meme rekonstrüksiyonu hastaya fizik ve psikolojik rahatlıklar sağlamaktadır. Postmastektomi meme rekonstrüksiyonu amacıyla kliniğimize başvuran hastalardan beşine; otojen doku olması, silikon proteze ihtiyaç göstermemesi, birçok kadında fazla olarak mevcut olan karın deri ve yağ dokusunun kullanılmasıyla aynı zamanda abdominoplasti de sağlaması gibi temel avantajlarından dolayı pediküllü Transvers Rektus Abdominis Myokutan (TRAM) flep uyguladık. Mastektomi ve rekonstrüksiyon arası zaman1.5-11 yıl idi. Dört hastaya karşı taraftan, bir hastaya aynı taraftan flep hazırlandı. Pediküllü TRAM fleple meme rekonstrüksiyonu; şekil ve pozisyon olarak karşı memeyle simetriyi sağlaması bakımından klinik olarak tatminkar bulundu.Day by day, there is an obvious increase in the number of patients demanding mammary reconstruction, after mastectomy because of mammary cancer. Postmastectomy breast reconstruction provides physical and psychological comfort to the patients. We used pedicled TRAM flap in five of the patients who administrated to our clinic for postmastectomy breast reconstruction, because of its basic advantages. These advantages could be summarized as follows; an autogenous tissue, there is no need to use silicon prosthesis and also provides abdominoplasty in these patients who have excess abdominal skin and fat.The time interval between the mastectomy and the reconstruction varied 1.5-11 years .Ipsilateral TRAM was used in one patient, contralateral TRAM was used in four patients. Mammary reconstruction with TRAM flap was found clinically satisfactory for providing symmetry to contralateral side in position and shape

    Detection and Classification of Volcanic Earthquakes/Tremors in Central Anatolian Volcanic Province

    Central Anatolia has been characterized by active volcanism since ∼10 Ma which created the so called CentralAnatolia Volcanic Province (CAVP) where a series of volcanoes are located along the NE-SW trend. Thepetrological investigations reveal that the magma source in the CAVP has both subduction and asthenosphericsignature possibly due to tearing of ongoing northward subduction of African plate along Aegean and Cyprusarcs. Recently, a temporary seismic array was deployed within the scope of Continental Dynamics: CentralAnatolian Tectonics (CD-CAT) project and provided a unique opportunity to study the deep seismic signature ofthe CAVP. Passive seismic imaging efforts and magnetotellurics (MT) observations revealed low velocity and highconductivity zones supporting the presence of localized partial melt bodies beneath the CAVP at varying depths,especially around Mt. Hasan which exhibits both geological and archeological evidences for its eruption around7500 B.C. In Central Anatolia, local seismicity detected by the CD-CAT array coincides well with the activefaults zones. However, active or potentially active volcanoes within CAVP are characterized by the lack of seismicactivity. In this study, seismic data recorded by permanent stations of Regional Earthquake-Tsunami MonitoringCenter were combined with temporary seismic data collected by the CD-CAT array to improve sampling densityacross the CAVP. Later, the continuous seismic waveforms of randomly selected time intervals were manuallyanalyzed to identify initially undetected seismic sources which have signal characters matching to volcanicearthquakes/tremors. For candidate events, frequency spectrums are constructed to classify the sources accordingto their physical mechanisms. Preliminary results support the presence of both volcano-tectonic (VT) and low-period (LT) events within the CAVP. In the next stage, the spectral and polarization analyses techniques will beutilized to the entire seismic database to detect and classify the seismic source associated to volcanism, and iden-tified events will be relocated and jointly interpreted with subsurface features detected by seismic imaging and MT

    PubMedID: 16700784Background: The purpose of this study was to describe the epidemiological and clinical features, course, response to treatment, and prognosis of pemphigus in the Mediterranean region of Turkey. Methods: All patients with confirmed pemphigus were prospectively enrolled in two major dermatology departments in the cities of Adana and Antalya in the Mediterranean region between March 1998 and March 2004. Details including demography, findings of clinical examinations, treatment, course, and prognosis were recorded. Results: One hundred and forty-eight patients with pemphigus were diagnosed during the 6-year period, with a prevalence of 1.46 and an annual incidence of 0.24 per 100,000 in this region. There was a female predominance with a male to female ratio of 1: 1.4. Pemphigus vulgaris (PV) was the most common clinical subtype, identified in 123 patients (83%). The mean age of onset was 43. In 101 (82%) patients with PV, disease began as persistent oral ulcers. The majority of the patients with PV could be managed with middle or high-dose steroids (60-140 mg/ day). Complete clinical remission was obtained in 41 (39.4%) patients. The mortality rate was 4.8%. Conclusions: A moderately high incidence of pemphigus was found in the Mediterranean region of Turkey as compared with that encountered in other countries. The commonest clinical subtype was PV with a 9.5-fold higher incidence than pemphigus foliaceus. It is more frequent in middle-aged people and has a female predominance. Although a relatively higher dose of steroid was needed to control the PV, the disease completely remitted in a significant proportion of the patients. © 2005 The International Society of Dermatology
