Item A Preliminary Investigation on the Presence of Calcifying Nanoparticles in the Breast Tumor(2014) Ozkal-Baydin, Pinar; Gocmen, Sedef J.; Erdemli, Esra; Tunc, Ibrahim G.; Sener, Hasan B.; Gumuskaya, Berrak; Sunguroglu, AsumanCalcium phosphate is deposited in many diseases, but the molecular basis of mineralization remains largely unknown. Biomineralizied calcifications that are formed by calcium deposits are also detected in breast mammograms. Some of the detected microcalcifications are thought to be related with malignancy. Taken together, calcifying nanoparticles (CNP) may be thought as a source of malign calcifications in breast cancers. The aim of the study is to research the presence of CNP in breast tumor tissue. With this aim, the presence of CNP was investigated by culturing 16 patients' breast tumor tissue and from 2 pathologic tissues with transmission electron microscopy (TEM) and scanning electron microscopy (SEM). Their growth was monitored by optical density (OD) at a wavelength of 650 nm. CNP couldn't be found in the analysed tissues. The presence of CNP in the breast tumor tissue was researched for the first time. We could not find CNP in the breast tumor tissue, but we think this research will open a new field of study for researchers.Item Massive Calcified Cerebellar Pilocytic Astrocytoma with Rapid Recurrence : A Rare Case(2016) Aydemir, Fatih; Kardes, Ozgur; Kayaselcuk, Fazilet; Tufan, Kadir; 0000-0002-1180-3840; 0000-0003-2854-941X; 0000-0003-1509-4575; 0000-0002-3400-9025; 27651876; AAE-2550-2021; P-5895-2018; AAK-1686-2021Pilocytic astrocytomas (PAs) are World Heath Organization Grade I tumors and are most common in children. PA calcification is not a common finding and has been reported more frequently in the optic nerve, hypothalamic/thalamus and superficially located cerebral tumors. We present a cerebellar PA in a 3-year-old male patient with cystic components and massive calcification areas. The residual tumor grew rapidly after the first operation, and the patient was operated on again. A histopathological examination revealed polar spongioblastoma-like cells. Massive calcification is not a common feature in PAs and can lead to difficulties in radiological and pathological differential diagnoses.Item Broncholithiasis presenting with lithoptysis(2018) Bozdas, Serife Savas; Ozyurek, Berna Akinci; 29970776Broncholithiasis is defined as calcified or ossified material in the bronchial lumen. The most frequently seen symptoms are a non-productive cough and hemoptysis. Occasionally, broncholytic expectoration can be seen, which is known as lithoptysis. As this is not a common finding, a case diagnosed with lithoptysis is presented here.
