Rheumatoid arthritis and periodontitis use analogous effector destructive procedures, in that the inflammatory cells and pro-inflammatory cytokines that drive chronic bone erosion in RA and chronic periodontal destruction in Periodontitis are alike. Periodontitis (PD) has appeared as a hazard factor in a number of health situations as rheumatoid arthritis (RA). To determine the effect of anti-tumor necrosis factor alpha biological treatment (methotrexate and Enbrel or infliximab) on periodontal status of patients having rheumatoid arthritis with periodontitis in comparison to those having periodontitis without rheumatoid arthritis and control healthy subjects and to determine the serum levels of anti-cyclic citrullinated peptide (ACCP) in these groups. Periodontal parameters used in this study were plaque index (PI), gingival index (GI), bleeding on probing (BOP) and clinical attachment level (CAL). Serum levels of anti-cyclic citrullinated peptide (ACCP) was estimated by enzyme linked immunosorbent assays (ELISA). The Blood samples were gathered from 75 patients (25 patients had rheumatoid arthritis with periodontitis, 30 patients with periodontitis only and 20 evidently healthy volunteers). The current data revealed that the median value of plaque and gingival indices were higher in the periodontitis group than in rheumatoid arthritis with periodontitis group while CAL was slightly higher in rheumatoid arthritis with periodontitis group than periodontitis group. The percentage of BOP sites were higher in periodontitis group than rheumatoid arthritis with periodontitis. The serum level of anti-cyclic citrullinated peptide was found to be higher in the periodontitis group (601.846) followed by rheumatoid arthritis with periodontitis, which had the lowest median (163.99), while the median value of ACCP in control group was (218.617), and the result was statistically non-significant difference between the study groups p> 0.05. There was no correlation between anticyclic citrullinated peptide and clinical periodontal parameters in each group except in gingival index, bleeding on probing of the periodontitis group as there was significant correlation. Patients with RA receiving biological treatment had lower anti_cyclic citrullinated peptide antibody and lower periodontal indices when compared with the other patient that not taking biological therapy. Thus, suppression of pro-inflammatory cytokines might have a beneficial effect in reducing inflammatory activity in rheumatoid arthritis disease and in minimizing the periodontal destruction of chronic periodontitis.
The aim of the research is to study the effect of the roundhouse strategy on the achievement of fifth grade secondary school in physics and their pivotal thinking. The experiment has been applied for obtaining the data, which were processed statistically using the Statistical Package for Social Sciences, the results revealed that the students of the experimental group who studied using the roundhouse strategy was superior to the students of the control group who studied in the traditional method in the achievement exam. The results also show that there are statistically significant differences between the mean scores of the students of the experimental group and the control group in the pivotal thinking exam, in favor of the experimental gr

Show MoreIn this study, the effects of blending the un-branched acrylate polymer known as Poly (n-decyl acrylate), and the branched acrylate polymer known as Poly (iso-octyl acrylate), on the viscosity index (VI), and the pour point of the Iraqi base stocks 40, and 60 respectively, were investigated. Toluene was used as a carrier solvent for both polymer types. The improvement level of oils (VI, & pour point) gained by blending the oil with the acrylate derived polymers was compared with the values of (VI, and pour point) gained by blending the oil with a commercial viscosity index, and pour point improver. The commercial lubricant additive was purchased and used by Al-Daura Refineries. It consisted of an un-known olefin copolymer dissolved i

The purpose of this study is to examine the effect of human resource diversity management practices on achieving entrepreneurship in Jordanian public universities. To achieve the aims of the study, a well-designed questionnaire was used for collecting data. The population of the study was (7433) faculty members (including different ranks such as professors, associate professors, assistant professors and lecturers) in Jordanian public universities. The study sample was selected through the use of a random sample, the questionnaire is distributed to a sample (of 400 with the percentage of 5%) selected by using a random sampling (350) copies of the questionnaire were collected, reaching about (87.5%) out of the sum total of the dist

One of the most important parameters determining structural members' durability and strength is the fire flame's influence and hazard. Some engineers have advocated using advanced analytical models to predict fire spread impact within a compartment and considering finite element models of structural components to estimate the temperatures within a component using heat transfer analysis. This paper presented a numerical simulation for a reinforced concrete beam’s structural response in a case containing Water Absorbing Polymer Spheres (WAPS) subjected to fire flame effect. The commercial finite element package ABAQUS was considered. The relevant geometrical and material parameters of the reinforced concrete beam model at elevated t
