Effect of Green Tea on the Level of Salivary Interleukin-1 Beta in Patients with Chronic Periodontitis: A Randomized Clinical Trial
AIM: Interleukin-1 beta (IL-1β) is one of the major biomarkers involved in the pathogenesis of chronic periodontitis. The aim of this study was to evaluate the changes in salivary IL-1β concentration in patients with chronic periodontitis following daily consumption of green tea. METHODS AND MATERIALS: Thirty patients with an average age of 45.8 years suffering from chronic periodontitis were randomly assigned into 2 groups (i.e., experimental and control groups). Besides receiving phase 1 periodontal treatment (scaling and root planning (SRP)), the experimental group drank green tea for a period of 6 weeks. To measure the concentration of salivary IL-1β, saliva samples were taken from both groups at 2 time points, i.e., prior to SRP (time point 1 (T0)) and after 6 weeks (time point 2 (T1)). The nonparametric Wilcoxon test was used to examine and compare the changes in the concentration of salivary IL-1β in each group relevant to the 2 time points (T0 and T1). Data were submitted to statistical analysis. RESULTS: At the end of the study period, a significant reduction (P=0.0001) in the concentration of salivary IL-1β was observed in the experimental group (A). As for the control group (B), however, there was no significant change (P=0.307) in the concentration of salivary IL-1β after 6 weeks following phase 1 periodontal treatment. CONCLUSION: Green tea supplementation, in addition to SRP, may reduce salivary IL-1β levels in patients with chronic periodontitis for a period of 6 weeks
Oral Health Related Quality of Life in Diabetic Patients
Background and aims. Diabetic patients display an increased risk of oral disorders, and oral health related quality of life
(OHRQL) might affect their management and treatment modalities. The aim of the present study was to determine OHRQL
and associated parameters in patients with diabetes.
Materials and methods. In this study two hundred patients were recruited from the diabetes clinic in Mustafa Khomeini
Hospital in Tehran, Iran. OHRQL was assessed using Oral Health Impact Profile Questionnaire (OHIP-20). Also, another
questionnaire was designed which contained questions regarding participants’ knowledge about oral complications of diabetes
and oral health behavior. OHRQL was categorized as low and good. Data were analyzed using logistic regression at P =
0.05.
Results. Of the diabetic patients assessed, 77.5% were in good and 22.5% were in low categories of OHRQL. This quality
was significantly associated with age (OR = 4.03, 95% CI = 1.63‒11.29), knowledge about diabetes oral complications (OR
= 18.17 95% CI = 4.42‒158.6), educational level (OR = 26.31 95% CI = 4.2‒1080.3), referred for dental visit by physician
(OR = 3.16 95% CI = 1.48‒6.69), frequency of brushing (OR = 10.29 95% CI = 3.96‒31.2) and length of time diagnosed
with diabetes (OR = 6.21 95% CI = 2.86‒13.63).
Conclusion. Oral health related quality of life was not negatively affected by diabetes mellitus in the assessed sampl
Association between Chronic Periodontitis and Serum Lipid Levels
Regarding the high prevalence of hyperlipidaemia, which is one of the major risk factors of cardiovascular disease, and uncertain reports about the relation between periodontal disease and serum lipid profile, this study was conducted to assess this relation. The historical cohort study was conducted on 52 cases including 26 persons with chronic periodontitis as case group, and 26 healthy subjects as control group. Both groups had the same age and weight ranges, sex, and diet, without any periodontal treatment history in the past six months, underling systemic disease such as diabetes, anti-hyperlipidemic drugs or active tobacco smoking history. Low Density Lipoprotein (LDL), High Density Lipoprotein (HDL), Triglyceride (TG) and Total Cholesterol (CHOL) were measured by direct enzymatic assay. TG level was 128.4±71.1 mg/dl in control group and 165.2± 83.7 in case group indicating a significantly higher level in case group (P<0.05). In control group, 30.8 percent and in case group, 61.5 percent had abnormal serum cholesterol levels, which presents a significantly higher level in case group (P<0.03). Other serum level indices did not show any significant difference. Although it seems that patients with chronic periodontal disease are more susceptible to hyperlipidemia, it is doubtful that the former causes an increase in serum lipid levels, so we suggest studying the effects of treating chronic periodontitis on serum lipid level
اللغة المزدوجة بين الممحوّ والمسطور: ابن عربي ودانتي / The Palimpsest of the Bilingual Author: Ibn ʿArabi and Dante
[Meddeb who was authored poetic, mystic and philosophical texts presents in this testimonial article his experience as a bilingual writer while wavering between direct and indirect modes of self-representation. Meddeb starts by describing his assimilation of language(s) in his childhood and ends with a figurative description of the tension inherent in his poetic activity as an Arab author writing in French. In the middle, Meddeb engages in a sophisticated analysis and comparison of Dante and Ibn \u27Arabi-his two maîtres de pensée-showing the unspoken of and the erased debt of Dante to Ibn \u27Arabi, specifically in the notion of al-khayal al-munfasil, detached imagination, as the foundation of visionary literature. Meddeb was brought up on the Tunisian dialect, which he considers his maternal tongue, and Quranic Arabic viewed as his paternal language, since his father-a Zeitouni Shaykh-taught it to him. In his lack of comprehension and yet complete captivation by the divine cadences, Meddeb associated ambiguity with the sacred and was awed by the fleeting meaning. Thus he experienced language as double. This was further reinforced when he enrolled in French schools. Meddeb speaks of his bilingually-informed creativity in a striking image: The undulation of French is like sea waves breaking on the shores of Arabic. The latter is guaranteed solidity by the immanence of the sacred. According to Meddeb, the liquidity of French and its rupture with the invariant begins with Dante who introduced the historical dimension into his otherwise imaginative and symbolic Divine Comedy. Ibn \u27Arabi, on the other hand, dismissed the real and the actual, apart from occasional autobiographical references, thus exemplifying medieval aesthetics with its single-minded preoccupation with the sacred.

Alif 22: The language of the self: autobiographies and testimonies
Autobiography is a protean genre: it covers so many forms and styles. When narrating one’s life, the narrator has to choose what he or she considers to be relevant and decisive. Beside the differences on what is fundamental in a life, the notion of the Self is culturally defined and thus varies from one place to another. The author of an autobiographical text may express only a fragment of his or her life, follow a thread in the trajectory through reminiscences, memoir, diaries, testimony, interview, letters, poems, etc. The author may declare openly that he or she is identical with the protagonist or may give the principal character a different name or no name. The author may depict private or public events, at times taking imaginative license or even including fantastic motifs. Autobiographical discourse is not only culturally conditioned; it is also symptomatic of the cultural moment. Thus it is important to explore the varieties of self-presentation, and not assume a fixed paradigm. In this revisionist spirit that looks for different and alternative ways of recording one’s life, Alif presents the autobiographical drive in multiple contexts: ancient and contemporary Egyptian; nineteenth-century and twentieth-century Arab, Moroccan, and Iraqi; South African and West African; Canadian and American; Palestinian and Sudanese; English and Irish; and even that of a hybrid background Chinese American and Algerian French. There has been a tremendous surge in autobiographical writing in recent years, and the field has been redefined by literary and cultural critics. From James Olney (ed.), Autobiography: Essays Theoretical and Critical (1980) to Dwight Reynolds (ed.), Interpreting the Self: Autobiography in the Arabic Literary Tradition (2001), a range of works have appeared challenging established views and approaches on the subject of autobiography. The epigraphs (whose English translation is drawn from the works mentioned above) attest to the complexity and diversity of motivations in writing about one’s past life.https://fount.aucegypt.edu/faculty_books/1170/thumbnail.jp
Nocturnal poetics: the Arabian nights in comparative context
The Book of a Thousand and One Nights, better known as The Arabian Nights, is a classic of world literature and the most universally known work of Arabic narrative. Although much has been written about it, Professor Ghazoul\u27s analysis is the first to apply modern critical methodology to the study of this intricate and much-admired literary masterpiece. The author draws on a wealth of critical tools -- medieval Arabic aesthetics and poetics, mythology and folklore, allegory and comedy, postmodern literary criticism, and formal and structural analysis -- to explain the specific genius of the The Arabian Nights. The author describes and examines the internal cohesion of the book, establishing its morphology and revealing the dialectics of the frame-story and enframed cycles of narrative. She discusses various forms of narrative -- folk epics, animal fables, Sindbad voyages, and demon stories -- and analyzes them in relation to narrative works from India, Europe, and the Americas. Covering an impressive range of writings, from ancient Indian classics to the works of Shakespeare and the modern writers Jorge Luis Borges and John Barth, she places The Arabian Nights in the context of an ongoing storytelling tradition and reveals its influence on world literature.https://fount.aucegypt.edu/faculty_books/1163/thumbnail.jp
Alif 24: Archaeology of literature: tracing the old in the new
This issue of Alif investigates the different strata constituting texts, and the presence of older material (myths, classics, hymns, rituals, romance, philosophical fragments, etc.) as subtexts in literature. Articles explore the processes and modalities of such inclusions in a given work or the corpus of an author. The issue also includes critical essays on the nature of continuity and correspondence in plots, characters, and styles as well as redeployment of older motifs in modern and postmodern works.
