    (2020) Yalcin Comert, Hatice Sonay; Eyuboglu, Ilker; Ersoz, Safak; Akdogan, Ali; Imamoglu, Mustafa; Sarihan, Haluk
    Aim: Although ovarian masses are rare in children, they differ forevery age group. We aimed to evaluate the management of patients diagnosed with ovarian masses in our clinic. Material and Methods: The medical records of patients (age ≤ 18) who underwent operations for ovarian masses during the period 2009-2019were evaluated retrospectively. Demographic findings, presenting symptoms and signs, the results of radiological examinations, mass locations and sizes, tumor markers, histopathological diagnoses and cases’surgical intervention were recorded.Results: The study included 51 patients with a total of 54 surgical interventions. There was a significant difference between tumor size and pathological diagnosis (p0.048) between the pathological diagnosis and the surgical intervention for patients who required oophorectomy and did not require oophorectomy (p=0.02) and presenting symptoms and signs with pathological diagnoses (p=0.027). We found no difference in the patients’ age of presentation and the pathological diagnoses (ovarian torsion, neoplastic or non neoplastic lesions) (p=0.542). We also found no difference between tumor markers and pathological diagnoses (p=0.253 for CEA, p=0.345 for αFP and p=0.129 for βHCG) or mass location (right or left side) with the pathological diagnoses (p=0.246).Conclusion: : Ovary preservation surgery is important for ovarian masses in children, and we must be careful when performing surgery on these patients.

    Physicochemical characteristics of a novel activated carbon produced from tea industry waste
    (Elsevier Science Bv, 2013) Gundogdu, Ali; Duran, Celal; Senturk, H. Basri; Soylak, Mustafa; Imamoglu, Mustafa; Onal, Yunus
    Tonnes of waste are generated during tea production in Turkey, one of the black tea producing countries in the world. These wastes are not used for any purposes throughout industrial sector. The objective of this study is to bring in economic value to waste materials by producing activated carbons from wastes of a tea plant and to characterize their physicochemical properties. Three types of activated carbons were produced by chemical activation using zinc chloride from tea industry wastes (TIW). Mesoporous structure and surface area rise as the ratio of ZnCl2/TIW increases. When the ratios of ZnCl2/TIW were selected as 1/2:1, 1:1, and 2:1, mesoporous activated carbons are found in the percentages of 10.9%, 39.9% and 77.7% with BET surface areas of 706, 1066 and 1141 m(2) g(-1), respectively. The resultant activated carbons were characterized by analyses of proximate-ultimate, FT-IR, SEM, TGA, methylene blue-iodine numbers, and surface functional groups. (C) 2013 Elsevier B.V.
