Circulating tumor cells in colorectal cancer - a review of detection methods and clinical relevance.

Colorectal cancer (CRC) is the third most common cancer; it is one of the leading malignancies contributing to cancer mortality. Colorectal cancer is the third most diagnosed cancer in men and the second in women worldwide. Diagnosis of CRC depends on several clinical features such as age, primary site, tumor-node-metastasis stage, genetic parameters and the presence or absence of metastasis.

An improved method for paraffin-embedded cytological preparations: application to the detection of circulating tumour cells.

Introduction: Conventional tissue biopsy is a key examination in cancer diagnosis. However, liquid biopsy is an alternative and less invasive solution that allows the detection of circulating tumour cells (CTCs). CTCs have emerged as a potential screening, diagnostic, and prognostic tool in cancer management.

Evaluation of the Antidepressant-like Effect of Chronic Administration of Nigella Fixed Oil Versus Fluoxetine in Rats.

Background: Depression is a group of syndromes characterized by notable and persistent mood disorders, and is one of the most prevalent psychiatric disorders, while the existing treatments have an altered risk-benefit balance. The therapeutic properties of Nigella have been confirmed, suggesting the reliance on phytotherapy.

Objectives: The objective of the present paper is to investigate the antidepressive-like effect of Nigella sativa on rats exposed to the Unpredictable Chronic Mild Stress procedure.

Anti-inflammatory potential of Capparis spinosa L. in vivo in mice through inhibition of cell infiltration and cytokine gene expression.

Background: Several chronic inflammatory diseases are characterized by inappropriate CD4+ T cell response. In the present study, we assessed the ability of Capparis spinosa L. (CS) preparation to orientate, in vivo, the immune response mediated by CD4+ T cells towards an anti-inflammatory response.

High incidence of MYCN amplification in a Moroccan series of neuroblastic tumors: comparison to current biological data.

MYCN protooncogene status was assessed for the first time in Morocco in peripheral neuroblastic tumors, including neuroblastoma, ganglioneuroblastoma, and ganglioneuroma. Correlations with age at diagnosis, stage, mitosis-karyorrhexis index, differentiation, and Shimada histology were evaluated. Thirty-six formalin-fixed, paraffin-embedded peripheral neuroblastic tumor tissue specimens collected between 2007 and 2010 from the Pathology Department were assessed for MYCN amplification using fluorescence in situ hybridization.

Immunohistochemical expression of CD44s in human neuroblastic tumors: Moroccan experience and highlights on current data.

Background: Peripheral neuroblastic tumors (pNTs), including neuroblastoma (NB), ganglioneuroblastoma (GNB) and ganglioneuroma (GN), are extremely heterogeneous pediatric tumors responsible for 15 % of childhood cancer death. The aim of the study was to evaluate the expression of CD44s ('s': standard form) cell adhesion molecule by comparison with other specific prognostic markers.

Methods: An immunohistochemical profile of 32 formalin-fixed paraffin-embedded pNTs tissues, diagnosed between January 2007 and December 2010, was carried out.
