Differential expression of "A Disintegrin and Metalloproteinase 10" in hepatocellular carcinoma and the noncancerous hepatic tissues: Contribution to HCV-promoted hepatocarcinogenesis.

Background: A disintegrin and metalloproteinases (ADAMs) have emerged as therapeutic targets in many cancers. ADAM10 was particularly studied in hepatocellular carcinoma (HCC) for its potential role in hepatocarcinogenesis and HCC progression.

Objective: To investigate the immunohistochemical (IHC) expression of ADAM10 in HCCs and the adjacent noncancerous tissues from 70 HCC patients, attempting to elucidate any association between ADAM10 and HCC development and/or progression.

Comparative Histological Study of Therapeutic Effect of Mesenchymal Stem Cells versus Mesenchymal Stem Cells Co-Cultured with Liver Tissue on Carbon Tetrachloride-Induced Hepatotoxicity in Adult Male Albino Rats.

Context: Liver diseases are major causes of morbidity and mortality. Mesenchymal stem cells (MSCs) have immunomodulatory, anti-inflammatory, and antifibrotic effects, so they can be used in the treatment of liver diseases. MSCs co-cultured with diseased liver tissue improve the homing capacity, survival rate, and paracrine effects of the MSCs, as well as the ability to enhance liver function.

Response of TLD-600/TLD-700 and CR-39 to neutrons for medical dosimetry.

In this study, thermoluminescence detectors (TLD)-600 and TLD-700 were used under different conditions to study neutron dosimetry for its application in medical dosimetry as albedo dosimeters. LiF has a high cross-section for neutrons and is more sensitive to neutrons than to gamma radiation. Conversely, TLD-700 showed a better response to gamma radiation.

No association between BRCA1 immunohistochemical expression and tumor grade, stage or overall survival in platinum-treated epithelial ovarian cancer patients.

Background: The aim of this work is to assess the frequency of BRCA1 protein immunohistochemical (IHC) expression in epithelial ovarian cancer (EOC) and to evaluate the association of BRCA1 expression with clinical and pathological characteristics and the overall survival (OS) of patients treated with postoperative platinum- based chemotherapeutic agents.

Materials And Methods: This retrospective study was conducted on 35 cases of epithelial ovarian cancer selected from the files of the Pathology Department, Faculty of Medicine, Mansoura University, Egypt. Immunohistochemistry (IHC) was performed for BRCA1 gene protein.

Low incidence of ADAMTS13 missense mutation R1060W in adult Egyptian patients with thrombotic thrombocytopenic purpura.

Thrombotic thrombocytopenic purpura (TTP) is an acute life-threatening disorder, characterized by thrombocytopenia, microangiopathic hemolytic anemia, widespread microvascular thrombi and consequent clinical sequelae due to ischemic organ damage. TTP is most commonly associated with deficiency or inhibition of von Willebrand factor-cleaving protease (ADAMTS13) activity. ADAMTS13 mutations and polymorphisms have been reported in childhood congenital TTP, but their significance in adult-onset TTP is still under investigation.
