Background and Objective: The PI3K/AKT/mTOR pathway is known to play an important role in regulating angiogenesis both in normal and breast cancer (BC) tissues. PIK3CA amplification was reported in various malignancies, including approximately 10% of BC cases. The aim of this study was to identify the frequency of PIK3CA amplification in Iranian female patient...
Large samples of tissue and biopsy specimen were taken from a single human liver, homogenized or paraffin-embedded, then analyzed by PIXE. Homogenates, including those of biopsies, proved to be suitable for PIXE-analysis of P, S, Ca, Mn, Fe, Cu, Zn, Se, Rb, Mo, Cd and, to a limited extent, Pb. Paraffin-embedding leads to a distinct elution of K, Rb, Cl and to a lesser elution of P, Zn, Se, Br a...
Osteosarcoma is the most frequent malignant bone tumor with a peak incidence in the second and third decades of life. Diagnosis of patients with osteosarcoma is limited to clinico-pathological parameters whereas molecular markers of tumor initiation and promotion have not yet been identified. We aimed to study the expression of the anti-apoptotic survivin gene in osteosarcoma specimens. A total...
Fungal rhinosinusitis (FRS) is commonly caused by various Aspergillus species (spp) and Mucorales fungi, and the treatment and prognosis of cases differ depending on the causative fungus. The present study describes a novel immunohistochemical method that has high sensitivity and specificity for distinguishing between these two types of fungi in patients with FRS. Three groups were included in ...
