Introduction: Bone marrow (BM) is a known source of mesenchymal stem cells (MSCs) that are used for cell therapy. This study attempts to identify if the Wharton’s Jelly (WJ) is a suitable substitute for BM as a source for MSCs. Materials and Methods: A population of human WJ and BM stem cells were isolated and incubated with fluorescein conjugated antibodies for five specific MSC markers....
Background: Thrombophilia is a main predisposition to thrombosis due to a procoagulant state. Several point mutations play key roles in blood-clotting disorders, which are grouped under the term thrombophilia. These thrombophilic mutations are methylenetetrahydrofolate reductase (MTHFR, C677T, and A1298C), factor V Leiden (G1691A), prothrombin gene mutation (factor II, G20210A), and plasminogen...
The diagnostic value of various signs and symptoms (clinical markers) in predicting oropharyngeal aspiration (OPA) or swallowing dysfunction has not been established in children. The present retrospective study was undertaken to: 1) identify specific clinical markers associated with radiographic evidence of OPA, isolated laryngeal penetration (ILP) and post-swallow residue (PSR); 2) determine t...
multiple sclerosis (ms) is a demyelinating disease of the central nervous system,with unknown etiology in which both genetic and environmental factors are thought to be involved. the hla system provides a set of genetic markers which lend themselves to systematic study. the disease also has variable clinical manifestations, ranging from a relapsing-remitting course to a chronic progressive dise...
BACKGROUND Incorporation of multiple enrichment biomarkers into prospective clinical trials is an active area of investigation, but the factors that determine clinical trial enrollment following a molecular prescreening program have not been assessed. PATIENTS AND METHODS Patients with 5-fluorouracil-refractory metastatic colorectal cancer at the MD Anderson Cancer Center were offered screeni...
Levels of biomarkers of exposure to selected harmful and potentially harmful smoke constituents found in cigarette smoke, in addition to nicotine were measured in 160 smokers randomized for 5 days to continuing smoking conventional cigarettes (41 participants), switching to Tobacco Heating System 2.2 (THS 2.2) (80 participants), or abstaining from smoking (39 participants). The data reported he...

introduction: acute myeloid leukemia (aml) is a clonal disease characterized by heterogeneous involvement of hematopoietic bone marrow cell populations. in aml patients, a variety of clinical and biologic parameters, including surface markers, have been examinedfor potential value in predicting treatment response and survival. by checking the myeloid, lymphoid and nonspecific markers on the bla...
Developments in biotechnology and genomics are providing a biological basis for the heterogeneity of clinical course and response to treatment that have long been apparent to clinicians. The ability to molecularly characterize human diseases presents new opportunities to develop more effective treatments and new challenges for the design and analysis of clinical trials. In oncology, treatment o...
The aim of this study was to show how, in some particular circumstances, a physical marker can be used along with molecular markers in the research of an ancient people movement. A set of five Alu insertions was analysed in 42 subjects from a particular Tunisian group (El Hamma) that has, unlike most of the Tunisian population, a very dark skin, similar to that of sub-Saharans, and in 114 Tunis...
