Immunohistochemical expression of Fas/Fasligand and c-Myc in oral lichen planus
...Show More Authors

Background: Oral Lichen Planus is a chronic inflammatory mucosal disease, presenting in various clinical forms .Both antigen-specific and non-specific mechanisms involved in the pathogenesis of OLP. Apoptosis or programmed-cell death is a physiological process essential for the normal development and maintenance of homeostasis in many organisms. Fas is a cell-surface glycoprotein, 40-kDa, that belongs to the nerve growth factor / tumor necrosis factor (TNF) receptor family. Fas is expressed in several tissues including blood, where its expression is upregulated on activated T and B lymphocytes and natural killer cells. Fas ligand is a type II transmembrane protein that belongs to the tumor necrosis factor family. The proto-oncogene c-Myc is a transcripation factor with roles in cellular proliferation, differentiation, apoptosis and cell cycle progression. Mutation in the c-Myc gene and protein over-expression has been associated with a variety of hematopoietic tumors, leukemias and lymphomas. Apoptosis is the mechanism that would be dysregulated in this disease. This study was conducted to evaluate the expression of Fas, Fasl and c-Myc in oral lichen planus and to correlate the expression of either markers with each other. Materials and Methods: This study was performed on thirty formalin- fixed paraffin-embedded tissue blocks of oral lichen planus pro and retrospectively. An immunohistochemical staining was done by using monoclonal antibodies for Fas, Fasl and c-Myc. Results: Expressions of Fas, Fasl and c-Myc were highly detected in keratinocytes and inflammatory cells of OLP cases compared to negative expression in normal oral mucosa. Significant correlation has been found between expression of Fas, Fasl and c-Myc in epithelial cells with that of inflammatory cells in oral lichen planus studied cases. Significant correlation has been found among expressions of Fas, Fasl and c-Myc in epithelial cells of oral lichen planus cases. Significant positive correlation found between expressions of Fas, Fasl and c-Myc in keratinocytes and inflammatory cells of oral lichen planus . Conclusion: Increased expression level of Fas, Fasl and c-Myc in both keratinocytes and lymphocytes of OLP cases in comparison to normal mucosa with highly significant correlation among the markers expression indicate their important role in malignant transformation of oral lichen planus.

The human self and its representations in the works of Salvador Dali
...Show More Authors

The products of the surrealist school since its inception to this day have greatly influenced art in the world, so we find many artists around the world invested in their visual texts the forms generated by surrealism, and here the researcher raises several questions: What are the formal vocabulary that directly or indirectly refers to Self-used by the surrealist painter? Was the surrealist form understood as intended by the movement? In these questions, the research problem is summarized. The importance of it lies in identifying the references to the form of the human self, which are related to the psychological field in the works of the surrealists, especially Salvador Dali. Then the researcher chose his research community from the wor

Comparative Study of Bacterial Contamination in Local Iraqi Sheep and Goats Semen
...Show More Authors

Background: Semen contamination is a detrimental factor in decreasing fertility. Seasonal changes may affect the contamination, too. Objectives: This study was designed to detect semen contamination in ovine and caprine during different seasons. Methods: Six fully mature male sheep and goats were subjected to electro-ejaculator collection twice monthly from February 1, 2022, to January 31, 2023 (Spring, February 1, 2022-April 30, 2022; Summer, May 1, 2022, July 31, 2022; Autumn August 1, 2022, October 31, 2022; Winter November 1, 2022, January 31, 2023), for studying the seasonal effect. A total of 288 semen samples were collected from both species (36 samples from each per season). All samples were subjected to bacterial isolatio

The research addressed an analytical field investigation of the locality of meander, the factors responsible of the locality of the meander at certain points of the stream other than others, and the role sequence of these factors in the formation process.
The research revealed that the location of forming the meander was associated closely with the scale structural composition of the bank materials from which the first stage of forming the curved stream, for the inhomogeneous or non-identical opposite banks in their scale structural composition saw an activity of differential corrosion, while the homogeneous and identical opposite banks in their scale structural composition saw an identical corrosion activity in its intensity at both

Examination of ‘Pause’ in Pinter's The Homecoming and Baker's Circle Mirror Transformation
...Show More Authors

Pauses as pragmatic markers are considered important devices that help readers to gain a better and deeper understanding of certain texts as well as speech, promoting effectively language communication. They can help both the speaker and the hearer, due to the functions they have in a text. Their occurrence in speech has a value that they make it more understandable. In this regard, the present study aims to examine the forms and functions of pauses in literary texts, more specifically, in selected extracts from two dramas, namely, Pinter's The Homecoming and Baker's Circle Mirror Transformation and to compare how the two writers use pauses in these two dramas. To do so, the sequential production approach of turn-taking by Sacks, Sc

Blindness and the Critique of Society: Dystopia in “Blindness” by José Saramago""
...Show More Authors

This paper addresses the new coloring in the concept of dystopian society as represented by the positive role of one of the characters vs. the passive role of the government and its mutual effect on the people of the society. In addition, it describes how all men in the dystopian society victimize and degrade the other through unlawful acts, like: stealing, rape, and fear, which are the lowest points in a moral decay. However, it offers hope by illustrating a positive sense, as exemplified by the doctor's wife out of Saramago's optimistic view that men may be descended from good women. Accordingly, the paper aims to examine the effect of the government’s role in the lives of the people who have later turned into blind in a dystopi
