Hematological malignancies remain one of the leading causes of death worldwide despite advances in cancer therapeutics. Newcastle disease virus (NDV) is a member of Paramyxoviridae that elicits considerable interest as an anticancer agent because it can replicate up to 10 000 times faster in human cancer cells than in most normal cancer cells. Several NDV strains reportedly induce the cytolysis of cancerous cell lines. The attenuated Iraqi strain (AMHA1) of NDV is a novel oncolytic agent with promising antitumor characteristics, including apoptosis induction. This study aimed to evaluate the ability of the AMHA1 NDV strain to induce apoptotic cell death in hematological tumors through caspase-dependent or independent apoptotic pathways. The cytolytic effects of AMHA1 NDV strains of different multiplicity of infection (MOIs) (20, 15,10, 5, 3, 1, 0.5, and 0.1 )and exposure for all hematological malignancy cell lines (human non-Hodgkin lymphoma SR and human multiple myeloma (COLO 677) and human monocytic leukemia THP1) have been determined through a microtetrazolium (MTT) assay. Propidium iodide and acridine orange (AO/PI) double staining were used to examine the ability of attenuated NDV strain to induce apoptosis in infected cells under a fluorescence microscope and to quantify the percentage of apoptosis induction. Quantitative immunocytochemistry assay was further used to study the caspase-dependent and independent protein expression levels in infected and control cells. Cells treated with NDV strains showed a higher cell-death percentage than untreated cells as quantified by the MTT assay. AO/PI results revealed that NDV exerted a powerful and significant effect on apoptosis induction (P<0.0001) in the human cancer cell lines tested in comparison with control cells. Immunocytochemistry in AMHA1 NDVinfected human hematological cell lines revealed a remarkable increase in the expression of caspase 8, 9 (dependent pathway), apoptosis-inducing factor, and endonuclease G (independent pathway) in comparison with untreated cells. This study demonstrated the role of the Iraqi NDV strain in inducing apoptosis through dependent and independent pathways in cancer cells and thus its high potential as an antitumor agent
Background: Behçet’s disease (BD) is a disorder of systemic inflammatory condition. Its important features are represented by recurrent oral, genital ulcerations and eye lesions. Aims. The purpose of the current study was to evaluate and compare cytological changes using morphometric analysis of the exfoliated buccal mucosal cells in Behçet’s disease patients and healthy controls, and to evaluate the clinical characteristics of Behçet’s disease. Methods. Twenty five Behçet’s disease patients have been compared to 25 healthy volunteers as a control group. Papanicolaou stain was used for staining the smears taken from buccal epithelial cells to be analyzed cytomorphometrically. The image analysis software has been used to

B cells have an essential contribution in immune system activation via the production of different cytokines and functioning as potent antigen-presenting cells. Therefore, a drug that particularly targets B cells may represent an ideal therapeutic approach for SLE. Rituximab (RTX), an anti-CD20 monoclonal antibody causing transient B-cell depletion, has been used to manage SLE. This study aims to assess Rituximab effects on lupus nephritis (LN) patients when added to conventional immunosuppressants. Twenty four patients, 15-32 years old, with class III/IV/V LN were involved in this study. All were on steroids before lupus nephritis occurrence. They were

The importance of this work focused on the use the green chemistry that is far from the chemical materials effect. The results of polarization presented the FIC inhibitor consider a mixed type (anodic and cathodic) inhibitor. Tafel curve used to evaluate the corrosion inhibition activity. In a saline medium, the best inhibitor efficiency reaches to (87%) in 2 ppm and IE% reach to (99%) for HCl medium inhibited by 1ppm. Langmuir isotherm obeys the study by thermodynamic pa
