The contribution of diffusion tensor imaging and magnetic resonance spectroscopy for the differentiation of breast lesions at 3T
(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
(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, ... -
Expression of 6 Common Antigenic Markers in Invasive Ductal Breast Carcinoma: Potential Clinical Implications
(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
(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
(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
(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
(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
(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
(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 ... -
Practical approaches to effective management of intestinal radiation injury: Benefit of resectional surgery
(2011)AIM: To study the outcome of patients undergoing surgical resection of the bowel for sustained radiation-induced damage intractable to conservative management. METHODS: During a 7-year period we operated on 17 cases (5 ... -
Ras suppressor-1 promotes apoptosis in breast cancer cells by inhibiting PINCH-1 and activating p53-upregulated-modulator of apoptosis (PUMA); verification from metastatic breast cancer human samples
(2015)Metastasis, responsible for most deaths from breast cancer (BC), is a multistep process leading to cancer cell spread. Extracellular matrix (ECM)-related adhesion and apoptosis resistance play pivotal role in metastasis. ... -
The role of antibiotic prophylaxis in elective tension-free mesh inguinal hernia repair: results of a single-centre prospective randomised trial
(2007)Hernia repair is one of the so-called clean operations. Many surgeons, however, use antibiotics, especially in the mesh repair era, without strong evidence to support this policy. We conducted a single-centre prospective ...
