Pheochromocytomas and paragangliomas (PPGL) are catecholamine-producing neuroendocrine tumors that display the highest heritability rate among all human tumors. Genomic analyses revealed the existence of 2 main clusters of PPGL, i.e. cluster 1 containing SDHx- and VHL-mutated tumors which do not produce epinephrine, and cluster 2 including epinephrine-secreting PPGL related to RET, NF1, TMEM127 and MAX mutations. Early diagnosis and treatment of PPGL is crucial to prevent adre...

Introduction: Low-grade pituitary gliomas are extremely rare neoplasms, originating from the pituicytes of the posterior pituitary or infundibulum. The incidence of these tumors increases with age and peaks in the seventh decade of life. Gliomas are primary brain tumors of the supporting glial cells of the central nervous system, which derive from neuroglial stem cells or progenitor cells. They are responsible for nearly 30% of all primary brain tumors and 80% of all malignant...

Objectives: The novel coronavirus disease-2019 (COVID-19) is the fastest-spreading disease worldwide, with over 380 million cases and 5 million deaths. The presence of diabetes mellitus (DM) in patients with COVID-19 was associated with mortality, acute respiratory distress syndrome, disease progression. COVID-19 was progressed with some hematological disorders, especially lymphopenia. Studies implicated that neutrophil-to-lymphocyte ratio (NLR) level can be a reliable marker ...

Metabolic changes in Type-2 Diabetes-Mellitus (T2DM) make patients more prone to develop osteoporosis and delayed bone healing. We hypothesize that microRNAs could be involved in the underlying mechanism and used as biomarkers in this context. To test this hypothesis, we analyzed microRNAs in samples from Zucker Diabetic Fatty (ZDF) rats, a T2DM model with reduced bone healing and bone mass. 11-week-old male ZDF and wildtype rats with a femur subcritical defect were treated wi...

Aim: To determine whether multiple fine needle passes to the same thyroid nodule in the fine needle aspiration biopsy (FNA) session affect sufficient and/or atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS) cytological result.Materials and Methods: Ultrasonography (US) and cyto-histopathology results of the nodules of patients who were diagnosed with thyroid nodules and underwent FNA between May-August 2021 wer...

Introduction: Patients with unresectable NENs are offered a variety of non-curable therapeutic options, which eventually fail due to drug resistance. Increasing evidence suggest an anticancer trait of cannabinoids, via cellular pathways including mTOR, known to be associated with drug resistance development. Still, limited data exist on the anti-cancer effects of cannabinoids in NENs.Aims: To understand the possible anti-tumor role of the cannabinoids an...
