The contribution of diffusion tensor imaging and magnetic resonance spectroscopy for the differentiation of breast lesions at 3T
Tsougos, I.; Svolos, P.; Kousi, E.; Athanassiou, E.; Theodorou, K.; Arvanitis, D.; Fezoulidis, I.; Vassiou, K. (2014)Background: Conventional breast magnetic resonance imaging (MRI), including dynamic contrast-enhanced MR mammography (DCE-MRM), may lead to ambiguous diagnosis and unnecessary biopsies. Purpose: To investigate the contribution ... -
Dynamic volatility and external security related shocks: The case of the Athens Stock Exchange
Athanassiou, E.; Kollias, C.; Syriopoulos, T. (2006)This paper analyses the impact of exogenous national security related shocks on the time-varying volatility structure of the Greek stock market. Alternative autoregressive conditional heteroscedastic models are estimated, ... -

(2011)Expression of estrogen (ER) and progesterone receptors, c-erbB-2 oncogene, mutant p53 antioncogene (mp53), e-cadherin adhesion, and apoptotic caspase-8 antigens in tumor relative to matched normal tissue specimens from 102 ... -
The Fat Content of Small Primary Breast Cancer Interferes with Radiofrequency-Induced Thermal Ablation
Athanassiou, E.; Sioutopoulou, D.; Vamvakopoulos, N.; Karasavvidou, F.; Tzovaras, G.; Tziastoudi, E.; Sakellariou, M.; Hatzitheofilou, C. (2009)Background: Radiofrequency (RF) thermal ablation is a minimally invasive technique of local mass elimination with variable efficiency. Methods: Ten patients with small primary breast cancer diagnosed preoperatively by core ... -
hTERT regulation by NF-kappa B and c-myc in irradiated HER2-positive breast cancer cells
Papanikolaou, V.; Athanassiou, E.; Dubos, S.; Dimou, I.; Papathanasiou, I.; Kitsiou-Tzeli, S.; Kappas, C.; Tsezou, A. (2011)Purpose: Telomerase activity (TA), frequently observed in cancer, compensates for telomere shortening thus preventing cell senescence and conferring resistance to therapy. In the present study, we investigated the expression ... -
Immunophenotypic Evaluation of DNA Mismatch Repair Markers in 2 Cases of Synchronous Histomorphologically Distinct Gastric Adenocarcinomas With Gastrointestinal Stromal Tumors of the Proximal Small Bowel
Athanassiou, E.; Vamvakopoulou, D. N.; Zacharoulis, D.; Paroutoglou, G.; Sioutopoulou, D.; Tepetes, K.; Nomikos, I.; Vamvakopoulos, N. C. (2010)Objectives: To assess the prognostic value of combined mismatch DNA repair (MMR) phenotyping in 2 synchronous histomorphologically distinct gastric adenocarcinomas (GADCs), each accompanied by gastrointestinal stromal ... -
Laparoscopic appendectomy: Differences between male and female patients with suspected acute appendicitis
Tzovaras, G.; Liakou, P.; Baloyiannis, I.; Spyridakis, M.; Mantzos, F.; Tepetes, K.; Athanassiou, E.; Hatzitheofilou, C. (2007)Background: The role of laparoscopy in the management of patients with suspected acute appendicitis remains controversial. It has been suggested that laparoscopy is useful mainly in young women of reproductive age because ... -
Mitogen-inducible gene-2 (MIG2) and migfilin expression is reduced in samples of human breast cancer
Gkretsi, V.; Papanikolaou, V.; Zacharia, L. C.; Athanassiou, E.; Wu, C.; Tsezou, A. (2013)Background: Cell adhesion proteins that connect each cell to neighboring cells and the extracellular matrix play a fundamental role in metastasis. Mitogen-inducible gene-2 (MIG2), is a cell-matrix adhesion protein, which ... -
On the mechanism of phenotypic conversion of human cervical adenocarcinoma HeLa cells surviving infection by influenza B virus: Potential implications for biological management of adenocarcinomas
Sioutopoulou, D. O.; Plakokefalos, E.; Arvanitis, L.; Athanassiou, E.; Venizelos, J.; Kaplanis, K.; Destouni, C.; Nomikos, I.; Satra, M.; Vamvakopoulos, N. C. (2008)We infected HeLa cells with low (10(-9) units), medium (10(-6) units), and high (10(-2) units) influenza B titers and compared the resulting human papilloma virus (HPV), retinoic acid receptor a subunit (RAR alpha) and ... -
