OBJECTIVE Our aim was to establish a correlation between hepatic stellate cells (HSCs) activity within different areas of hepatic tissue and the degree of liver fibrosis, necroinflammation, and steatosis in patients with viral C chronic liver disease. PATIENTS AND METHODS We prospectively included 41 liver biopsies from patients with chronic hepatitis C(More)
The present study shows the histopathological and immunohistochemical aspects encountered in 49 benign tumors with neural origin diagnosed in the Pathology Department of the Emergency County Hospital of Craiova between 2000 and 2007. Histopathological criteria were used for the histopathological diagnosis, having been diagnosed 22 neurofibromas and 27(More)
UNLABELLED Cystic lymphangiomas are benign tumors developing as an anomaly of the lymphatic channels. Most of them are discovered in children and are located mostly in the head and neck with no differences between sexes. Retroperitoneal locations are rare, clinical symptoms not specific and are discovered incidentally. We report the case of a 32-year-old(More)
BACKGROUND In patients with high-stage colorectal carcinomas (CRC), anti-EGFR therapy is known to be effective only in cases with a wild-type K-ras gene status. Different procedures have been proposed for such evaluation. MATERIALS AND METHODS The mutation status of K-ras gene, codons 12, 13 and 61 was determined in 250 CRC cases using the pyrosequencing(More)
The review pinpoints operational concepts related to the redox biology network applied to the pathophysiology and therapeutics of solid tumors. A sophisticated network of intrinsic and extrinsic cues, integrated in the tumor niche, drives tumorigenesis and tumor progression. Critical mutations and distorted redox signaling pathways orchestrate pathologic(More)
Lymphomas represent malignant lymphoproliferative diseases and they are generally classified as Hodgkin's (HL) or non-Hodgkin malignant lymphomas (NHML). Head and neck lymphomas represent one of the most common sites of extranodal lymphomas, second after the gastrointestinal tract. Waldeyer's ring structures include the palatine tonsils, the nasopharyngeal(More)
Histopathological diagnosis using Formalin-Fixed Paraffin Embedded (FFPE) tissues is essential for the prognostic and therapeutic management of cancer patients. Pathologists are being confronted with increasing demands, from both clinicians and patients, to provide immunophenotypic and gene expression data from FFPE tissues to allow the planning of(More)
Iron oxide nanoparticles are promising candidates for theranostics in cancer, that aims to achieve in one-step precise tumor imaging by magnetic resonance, and targeted therapy through surface attached anti-cancer drugs. The aim of this study was to investigate in preclinical setting the biocompatibility of new iron oxide-based nanoparticles that were(More)
Routine histopathological criteria are poor predictors of the outcome in meningiomas. The present study tried to determine if some adhesion cell molecules could be helpful in assessing the histological aggressiveness in meningiomas of all grades. Our series comprised 113 cases, WHO grade I (n=53), WHO grade II (n=47) and WHO grade III (n=13). Three cases of(More)
BACKGROUND AND AIMS Hepatocellular carcinoma (HCC) remains a leading cause of death by cancer worldwide. Computerized diagnosis systems relying on novel imaging markers gained significant importance in recent years. Our aim was to integrate a novel morphometric measurement--the fractal dimension (FD)--into an artificial neural network (ANN) designed to(More)
