Association of intercellular adhesion gene A with biofilm formation in staphylococci isolates from patients with conjunctivitis.

Background: There is a great negative impact of biofilm-mediated infection on patient health which necessitates the use of reliable methods for detecting biofilm producers.

Aims: This study was done to determine biofilm-producing ability and the presence of a g A in clinical staphylococcal isolates and to assess the reliability of two phenotypic methods used for biofilm detection.

Materials And Methods: Fifty staphylococcal strains were isolated from 100 conjunctival swabs from patients attended the Ophthalmology Outpatient Department of the Research Institute of Ophthalmology.

Gene polymorphisms of Interleukin 1? and Metalloproteinase 3 in Hepatitis C Infected Patients and Hepatocellular Carcinoma Patients.

Cytokines as IL 1? and matrix metalloproteinases (MMPs) are involved in tumor growth, invasion, and remote metastasis in various cancers. IL-1? ?31T/C polymorphism in the promoter region has been linked to an elevated risk of Hepatocellular carcinoma (HCC). MMP3 polymorphism at 1171 has also been linked to an elevated risk and a highly invasive type of HCC.

Percentage of CD3-CD56+dim and of CD3-CD56+dimCD69+ Natural Killer Cells in the Peripheral Blood of Women with In Vitro Fertilization (IVF) Failure.

CD56dim cells, potent mediators of natural cytotoxicity, have direct contact with chorionic villi at the intervillous space. The manner the developing fetus evades NK cytotoxicity from these cells may determine the pregnancy outcome. CD69 is one of the earliest cell surface activation markers expressed by NK cells.

Evaluation of rezasurin microtiter assay and high resolution melting curve analysis for detection of rifampicin and isoniazid resistance of Mycobacterium tuberculosis clinical isolates.

Background: Several methods have been proposed for rapid detection of drug resistance of Mycobacterium tuberculosis (M. tuberculosis). High resolution melting (HRM) curve analysis has been developed for accurate and simultaneous detection of resistance of M.
