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.

The United States of America guarantees Western Europe and Japan the process of access to energy sources and the exclusion of its opponents from the region, especially the Soviet Union, and the growing American military presence in the Gulf after the invasion of Iraq in 2003. On the other hand, the region experiences many contradictions, some of which threaten its security, such as the exacerbation of disputes between its count

... Show MoreSince the emergence of the science of international relations as an independent academic scientific field, various theories and trends have appeared and have tried to understand and explain the international reality and give a clear picture of what is happening within the international system of interactions and influences and the search for tools for stability and peace in international relations. Among these theories is the feminist theory, which is a new intellectual trend on the level of international relations theories, which tried to give an explanation of what is happening in world politics and in international relations in particular. The main issue that feminist theory is concerned with is the lack of women’s subordination

In the present study two species of Cyclopoida: Copepod, Mesocyclops hyalinus and Cyclops agilis آ were used as predators for Anophles larvae.
The data showed that the percentages of predation were 65% and 56%

The present study describes the cytoarchitecture characteristics of a local dog’s mature adult reproductive tract. Materials and Methods: Sixteen samples of uterus and cervix were obtained from local breed bitches to conduct this study. The organs were processed according to routine histopathological protocol and stained with hematoxylin and eosin, Masson’s trichrome, and combined Alcian blue (2.5 pH) and PAS (AB-PAS) stains. Results: The mature endometrium formed numerous short epithelial folds and epithelial crypts composed of mucous cells and cuboidal cells. The core of the endometrium is c
