Immunohistochemical expression of MMP9, as a marker of local invasion in Hodgkin’s and Non-Hodgkin’s lymphoma of the head and neck region
...Show More Authors

Background: Malignant lymphoma is the generic term given to tumors of the lymphoid system and specifically of lymphocytes and their precursor cells, While all lymphomas are malignant neoplasms, there is a wide spectrum of clinical behavior, with some following an indolent clinical course and others behaving in an aggressive manner (will causing death in a short time frame if left untreated). The metastatic process involves intravasation and extravasation of tumor cells, followed by reimplantation of tumor cells, formation of a new tumor stoma, Degradation of the extracellular matrix and components of the basement membrane by proteases facilitates the detachment of tumor cells, their crossing of tissue boundaries, and invasion into adjacent tissue compartments. The importance of tumor-associated proteases in invasion and metastasis has been demonstrated for a variety of solid malignant tumors. MMP family has been implicated in tumor cell invasion and metastasis. Material and methods: This study included 67 formalin-fixed, paraffin-embedded histopathologically diagnosed lymphoma blocks (head and neck lesions), 24 Hodgkin’s Lymphoma and 43 Non Hodgkin’s Lymphoma. Immunohistochemical (IHC) evaluation of MMP-9 monoclonal antibodies), in relation to the clinicopathological parameters was assessed. Results: The mean of expression of MMP-9 in NHL was higher (65.4±18) than that in HL (56.7±21.4) though it did not reach the level of statistical difference P > (0.05), while the mean of expression of MMP-9 in relation to tumor grades was different as it had a value of (72±14.1) in low grade tumors, (68.3±15) in the intermediate grade tumor and (61.4±20.7) in high grade tumors; consequently, this difference did not reached the level of statistical significance P(ANOVA) >0.05 . MMP 9 had no statistical significant correlation in regard to its mean in HL subtypes. Conclusions: This study had shown that there was no significant correlation between age and mean of expression of MMP-9 in HL and NHL. There was no statistical significant difference in the mean of expression of MMP-9 between HL and NHL subtypes. Keywords: MMP-9, local invasion, Hodgkin’s lymphoma, Non Hodgkin’s Lymphoma.

Design, Synthesis, and Docking Study of Acyl Thiourea Derivatives as Possible Histone Deacetylase Inhibitors with a Novel Zinc Binding Group
...Show More Authors

Histone deacetylase inhibitors with zinc binding groups often exhibit drawbacks like non-selectivity or toxic effects. Thus, there are continuous efforts to modify the currently available inhibitors or to discover new derivatives to overcome these problems. One approach is to synthesize new compounds with novel zinc binding groups. The present study describes the utilization of acyl thiourea functionality, known to possess the ability to complex with metals, to be a novel zinc binding group incorporated into the designed histone deacetylase inhibitors. N-adipoyl monoanilide thiourea (4) and N-pimeloyl monoanilide thiourea (5) have been synthesized and characterized successfully. They showed inhibition of growth of human colon adenoc

Fabrication and characterization of zinc oxide nanorods coated by graphene oxide ZnO-NR@GO as a potential hybrid material photocatalyst
...Show More Authors

Hybrid architecture of ZnO nanorods/graphene oxide ZnO-NRs@GO synthesized by electrostatic self-assembly methods. The morphological, optical and luminescence characteristics of ZnO-NRs@GO and ZnO-NRs thin films have been described by FESEM, TEM, HRTEM, and AFM, which refers to graphene oxide have been coated ZnO-NRs with five layers. Here we synthesis ZnO-NRs@GO by simple, cheap and environmentally friendly method, which made it favorable for huge -scale preparation in many applications such as photocatalyst. ZnO-NRs@GO was applied as a photocatalyst Rodamin 6 G (R6G) dye from water using 532 nm diode laser-induced photocatalytic process. Overall degradation of R6G/ ZnO-NRs@GO was achieved after 90 minutes of laser irradiation while it ne

Natural preparation of rice husk-derived silica and eggshell-derived calcium carbonate composite as a coating material for dental implant
...Show More Authors

Background: The world is in front of two emerging problems being scarceness of virgin re-sources for bioactive materials and the gathering of waste production. Employment of the surplus waste in the mainstream production can resolve these problems. The current study aimed to prepare and characterize a natural composite CaO-SiO2 based bioactive material derived from naturally sustained raw materials. Then deposit this innovative novel bioactive coating composite materials overlying Yttria-stabilized tetragonal zirconia substrate. Mate-rials and method; Hen eggshell-derived calcium carbonate and rice husk-derived silica were extracted from natural resources to prepare the composite coating material. The manufac-tured powder was characterized

Study of ELISA and antibiotic sensitivity test for Salmonella enteritidis as experimental infection in mice
...Show More Authors

Salmonella enteritidis one of more important as epidemiological bacteria between other salmonella types. It is very important pathologically that cause food poising and gastrointestinal tract infections. This study includes some of immunological changes that appear by ELISA test and antibiotic sensitivity test against these bacteria in mice. ELISA test results appears high immunological response happen after 3 days of inoculation, mean titration readings beginning 0.198 and the maximum mean titration after 15 days of inoculation 1.538 and begin to decrease after this time slowly to remain about 0.297 after 40 days of inoculation. An antibiotics sensitivity test result appears, this bacteria sensitive to Chloramphenicol, Ceftriaxone,

Experimental and Theoretical Study of Neomycin Sulfate as Corrosion Protection for Titanium in Acid Media
...Show More Authors

        The experimental and theoretical methods were studied for inhibition of the corrosion titanium in HCl by using neomycin sulfate drug. The results of neomycin sulfate drug had good corrosion protection for titanium in hydrochloric acid and the inhibition efficiency (%IE) increasing with increasing concentration of drug because the neomycin sulfate drug had adsorption from acid solution on surface of titanium metal. The program of hyperchem-8.07 was used for theoretical study of the drug by molecular mechanics and semi-empirical calculations. Quantum chemical was studied drug absorption and electron transferred from the drug to the Titanium metal, also inhibition potentials of drug attachment with the (LUMO-HOMO) energy gap,
