The effect of tranexamic acid on blood loss in liposuction: a randomized controlled study.

Background: Liposuction is one of the most common procedures in the practice of plastic surgery. Since it evolved, continuous modifications have been to decrease blood loss so that patients are hemodynamically stable intra- and postoperatively. Tranexamic acid (TXA) has long been used for its antifibrinolytic properties that were beneficial in reducing blood loss, rate of transfusion, and hemoglobin drop in major trauma and surgeries.

TAp73 and ΔNp73 relative expression in Egyptian patients with lymphoid neoplasms.

Background And Aims: The p73 gene has different isoforms with opposing anti- and pro-apoptotic functions. The pro-apoptotic activities are inhibited by overexpression of the dominant ΔNp73 isoform. The aim of this study was to detect the expression of the TAp73 and ΔNp73 isoforms in Egyptian patients with malignant lymphoid neoplasms.

Impact of Prothrombotic Risk Factors in a Cohort of Egyptian Hemophilia A Patients.

Introduction: Hemophilias are a group of related bleeding disorders that show an X-linked pattern of inheritance. The clinical phenotype of severe hemophilia may vary markedly among patients as a result of many factors, including genetic prothrombotic risk factors.

Objectives: Our objective was to study the incidence of the most common prothrombotic risk factors for additive effects among Egyptian patients with hemophilia A and their impact on clinical phenotype; annual bleeding frequency and severity of hemophilic arthropathy, as well as the effect of a single variation in these patients.

Interleukin 28B polymorphisms and therapy response in Egyptian hepatitis C genotype-4 patients.

Hepatitis C infection represents a major health problem in Egypt; only 20% of patients undergo spontaneous clearance of the virus and around 25% of all patients progress to develop cirrhosis. More than 90% of Egyptian patients have hepatitis C virus (HCV) genotype-4. Combined pegylated interferon and oral ribavirin are the current standard therapies for HCV-4.

Stromal cell derived factor-1 (CXCL12) chemokine gene variant in myeloid leukemias.

Background: Acute and chronic myeloid leukemia are initiated and sustained by a small, self-renewing population of leukemic stem cells, which produce progeny of a heterogeneous population of progenitor cells. CXCL12, a chemokine abundantly produced by the bone marrow microenvironment, and its receptor CXCR4 have crucial roles in malignant cell trafficking. We set out to determine the CXCL12 gene polymorphism at codon G801A and evaluate its influence on malignant cell dissemination and tissue infiltration in myeloid leukemias.

Excision repair cross-complementing group 2/Xeroderma pigmentousm complementation group D (ERCC2/XPD) genetic variations and susceptibility to diffuse large B cell lymphoma in Egypt.

Diffuse large B-cell lymphoma (DLBCL) is a genetically heterogeneous neoplasm. Although several genetic and environmental factors have been postulated, no obvious risk factors have been emerged for DLBCL in the general population. DNA repair systems are responsible for maintaining the integrity of the genome and protecting it against genetic alterations that can lead to malignant transformation.
