Screening and diagnostic methods like mammography, ultrasound or magnetic resonance imaging are not enough for all clinical situations to conclude about the exact nature of the lesions found in the breast tissue. Therefore, physicians need biopsy as an invasive procedure. The aim of this study was to investigate the electrical impedance of abnormal and normal breast tissue, in order to find a new method, for reliable, non-invasive detection of breast cancer. For this purpose, breast tissues taken from five patients were provided Bezmialem Vakif University Faculty of Medicine Department of General Surgery, and impedance measurements have been done at the Pathology Department of the same university. Impedances of healthy and tumoral tissues for each patient were measured. Analysis of impedance values has shown significant difference between healthy and tumoral tissuesPublication Metadata only Unusual Histopathological Findings in Appendectomy Specimens: A Retrospective Analysis of 2047 Cases.(2019-04-01) UNVER, NURCAN; COBAN, GANİME; ARıCı, DİLEK SEMA; BUYUKPıNARBASıLı, NUR; Gucin, ZÜHAL; MALYA, FATMA ÜMİT; ONARAN, OI; TOPALAN, K; ÜNVER, NURCAN; ÇOBAN, GANİME; ARICI, DILEK SEMA; BÜYÜKPINARBAŞILI, NUR; GÜCİN, ZÜHAL; MALYA, FATMA ÜMİTPublication Metadata only p53 expression and relationship with MDM2 amplification in breast carcinomas(2016-04-01) Buyukpinarbasili, NUR; Gucin, ZÜHAL; Ersoy, YELİZ EMİNE; ILBAK, Ayca; Kadioglu, HÜSEYİN; Muslumanoglu, Mahmut; BÜYÜKPINARBAŞILI, NUR; GÜCİN, ZÜHAL; ERSOY, YELIZ EMINE; KADIOĞLU, HÜSEYİNCarcinoma of the breast, like other malignancies, is a genetic disease with multiple genetic events leading to the malignant phenotype. p53 mutations are the most common genetic events in human cancer. Inactivation of p53 can be a result of mutation in gene sequence. One of the main structures that regulate p53 stabilization is MDM2. It suppresses p53 transcriptional activation by recognizing transactivation domain of p53. The loss of MDM2 function on p53 regulation results in deprivation of p53 tumor suppressor ability. Single nucleotide polymorphisms (SNP309 T->G exchange) or MDM2 amplification has been proposed to play a role in this issue. In the present study, our aim is to analyze p53 and MDM2 status and investigate their interactions in human sporadic breast carcinoma. The study groups were separated according to their molecular classifications. In each group, histologic type of the tumor, conventional prognostic parameters, p53, and MDM2 interactions were compared statistically. Tumors are divided into 4 subtypes due to estrogen and progesterone receptor status, HER-2, and Ki-67 proliferation index results. According to this classification, 23 cases are in the luminal A, 32 cases are in the luminal B, 15 cases are in the HER-2 positive, and 22 cases are in the triple-negative group, with a total of 92 cases. p53 expression is low in luminal breast carcinomas than HER-2 and triple-negative subtypes. MDM2 amplification frequency was found to be 5.4% in total. MDM2 gene amplification does not have a significant role in breast carcinogenesis, but other possible mechanisms may play a role in its inactivation. (C) 2016 Elsevier Inc.

Few reports have explored whether 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) might be more useful than other diagnostic methods in these contexts.Publication Open Access Comparison of MRI Features of Invasive Pleomorphic and Classical Lobular Carcinoma: Differentiation Is Possible?(2022-01-01T00:00:00Z) YILMAZ, TEMEL FATİH; OTÇU TEMUR, HAFİZE; SARI, LÜTFULLAH; GÜCİN, ZÜHAL; GÜLTEKİN, MEHMET ALİ; ÇELİK YABUL, FATMA; TOPRAK, HÜSEYİN; YILDIZ, ŞEYMA; YILMAZ, TEMEL FATİH; OTÇU TEMUR, HAFİZE; SARI, LÜTFULLAH; GÜCİN, ZÜHAL; GÜLTEKİN, MEHMET ALİ; ÇELİK YABUL, FATMA; TOPRAK, HÜSEYİN; YILDIZ, ŞEYMATo evaluate breast MRI and DWI and demographic features of pleomorphic invasive lobular carcinoma (pILC) and classic invasive lobular carcinoma (cILC). Invasive lobular (ILC) is the second most common breast malignancy after invasive ductal carcinoma (IDC) and constitutes the 8-14% of all invasive breast cancers. ILC morphologically can be classified into the classic, alveolar, solid, tubulolobular, and pleomorphic subtypes according to WHO. This study was performed retrospectively. The MRI and demographic features of 18 patients with 23 pILC were compared with those 22 consecutive patients with 27 cILC. There was no significant difference in demographic features of patients, MR appearance, kinetics, and ADC values between two groups. pILC, an aggressive subtype of ILC, cannot be differentiated from cILC with breast MRI.Publication Metadata only Skin Recurrence of a Phylloides Tumor and Impacy of Radiotherapy A Case Report and Review of The Literature(2013-01-01) YÜCEL, SERAP; KADIOĞLU, HÜSEYİN; GÜRAL, ZEYNEP; YILDIZ, ŞEYMA; YILDIZ, ŞEYMA; GÜCİN, ZÜHALPublication Open Access A Six Sigma Trial For Reduction of Error Rates in Pathology Laboratory(2016-09-01) TURNA, Seval; Tosuner, ZEYNEP; Gucin, ZÜHAL; Kiran, TUĞÇE; Buyukpinarbasili, NUR; TASKIRAN, Olcay; Arici, DİLEK SEMA; TOSUNER, ZEYNEP; GÜCİN, ZÜHAL; KIRAN, TUĞÇE; BÜYÜKPINARBAŞILI, NUR; TURNA, SEVAL; ARICI, DILEK SEMAObjective: The aim of this study is to determine differences of levels of empathy among undergraduates in each year of their four-year programs of physiotherapy. Methods: During the 2014-2015 academic school year, 381 physiotherapy students were enlisted from two universities in Istanbul, one a foundation and the other a government university. The Turkish version of the Jefferson Scale of Physician Empathy was administered. Students were asked to indicate interest in particular physiotherapy specialties as well as their region of origin in Turkey. The Kruskal-Wallis analysis was used to determine differences among the four study years, and also to measure relationships between specialty interest, home-region, and empathy scores of the students. Empathy scores were also compared according to gender. Results: The difference of empathy scores between the students of the two universities was borderline significant (p=0.057). Empathy scores in both universities increased to a significant degree after school entrance and decreased in the final year. Levels of empathy did not change according to gender, specialty interest, or home-region (p=0.722, 0.524, and 0.309, respectively). Conclusions: This study points to the need for physiotherapy curricula that would enhance empathy and give students practice in exhibiting this valuable attribute. Additional studies are needed that would include larger study populations and track the same students year by year as to how and why their empathy levels change during their training.Publication Metadata only Primer Meme Lenfoması; Yineleyen Hastalık,(2012-05-01) KADIOGLU, HÜSEYİN; YUCEL, SERAP BASKAYA; GÜRAL, ZEYNEP; GÖZÜBÜYÜKOGLU, NURHAN; AKGÜN, ZÜLEYHA; YILDIZ, ŞEYMA; GÜCİN, ZÜHAL; BOZKURT, SÜLEYMAN; ERSOY, YELİZ EMİNE; SAGLAM, ESRA KAYTAN; KADIOĞLU, HÜSEYİN; YILDIZ, ŞEYMA; GÜCİN, ZÜHAL; BOZKURT, SÜLEYMAN
