Background: Diabetes mellitus is a major risk factor for chronic periodontitis (CP) and hyperglycemia has an important role in the enhancement of the severity of the periodontitis. It has been reported that the progression of CP causes shifting of the balance between bone formation and resorption toward osteoclastic resorption, and this will lead to the release of collagenous bone breakdown products into the local tissues and the systemic circulation. Cross-linked N-telopeptide of type I collagen (NTx) is the amino-terminal peptides of type I collagen which is released during the process of bone resorption. This study was conducted to determine the effects of nonsurgical periodontal therapy on serum level of NTx in type 2 diabetic patients with chronic periodontitis (CP) and in systemically healthy patients with CP and to correlate NTx level with the clinical periodontal parameters in the studied groups. Materials and methods: The studied sample consisted of ninety subjects of both genders with an age range (35-55). They were divided into three groups, the first group consisted of 30 subjects with healthy periodontium and systemically healthy (control group), the second group consisted of 30 patients having chronic periodontitis and type 2 diabetes mellitus (CPDM) group, and the third group consisted of 30 patients with chronic periodontitis only and systemically healthy (CP) group. All the subjects enrolled in this study were with normal body mass index. The clinical periodontal parameters measured were plaque index (PLI), gingival index (GI), probing pocket depth (PPD), and relative attachment level (RAL). The blood samples were collected from all individuals and examined to measure the serum level of NTx using enzyme-linked immune sorbent assay (ELISA). Patients with chronic periodontitis were treated with scaling and root planning (SRP) and recalled for further measurements of the clinical periodontal parameters and collection of the blood sample to measure the serum level of NTx after eight weeks. Results: All the clinical periodontal parameters at the baseline were higher than that after treatment. PPD and RAL were highest in CPDM group followed by CP. Regarding the level of NTx at the baseline; it was highest in CPDM group followed by CP group then the control group. After treatment, results revealed a reduction in NTx level for both CPDM and CP groups. Regarding the correlation between the clinical periodontal parameters and NTx level, the results revealed almost a non-significant weak positive correlation. Conclusions: SRP is an impactful procedure and results in the improvement of all the clinical periodontal parameters and reduction in the serum level of cross-linked N-telopeptide of type I collagen which could be considered as a good bone resorption marker in the studied groups.
Transient mixed convection heat transfer in a confined porous medium heated at periodic sinusoidal heat flux is investigated numerically in the present paper. The Poisson-type pressure equation, resulted from the substituting of the momentum Darcy equation in the continuity equation, was discretized by using finite volume technique. The energy equation was solved by a fully implicit control volume-based finite difference formulation for the diffusion terms with the use of the quadratic upstream interpolation for convective kinetics scheme to discretize the convective terms and the temperature values at the control volume faces. The numerical study covers a range of the hydrostatic pressure head , , , , and ), sinusoidal amplitude range of

Low conversion copolymerization of acrylamide AM (monomer-1) have been conducted with acrylic acid AA in dry benzene at 70°C , using Benzoyl peroxide BPO as initiator . The copolymer composition has been determined by elemental analysis. The monomer reactivity ratios have been calculated by the Kelen-Tudos and Finman-Ross graphical procedures. The derived reactivity ratios (r1, r2) are: (0.620, 0.996) for (AM / AA) systems , and found that the reactivity of the monomer AA is more than the monomer AM in the copolymerization of (AA/AM) system. The reactivity ratios values were used for microstructures calculation.

Document clustering is the process of organizing a particular electronic corpus of documents into subgroups of similar text features. Formerly, a number of conventional algorithms had been applied to perform document clustering. There are current endeavors to enhance clustering performance by employing evolutionary algorithms. Thus, such endeavors became an emerging topic gaining more attention in recent years. The aim of this paper is to present an up-to-date and self-contained review fully devoted to document clustering via evolutionary algorithms. It firstly provides a comprehensive inspection to the document clustering model revealing its various components with its related concepts. Then it shows and analyzes the principle research wor

Background: Polycystic ovary syndrome (PCOS) is
the most common form of chronic anovulation
associated with androgen excess; it occurs in about 5
– 10% 0f reproductive age women. Metabolic
syndrome is characterized by insulin resistance,
hypertension, obesity, abnormalities of blood clotting
and dyslipidemia.
Adult women with PCOS have an increased
prevalence of the metabolic syndrome(MBS).
Objectives: To detect the prevalence of metabolic
syndrome in women with proved PCOS, attending the
Specialized Center for Endocrinology and Diabetes, in
Baghdad.
Materials and methods : A total number of 40
women with proved PCOS were included in this study
which was conducted in the Specialized Center f
In this paper we generalize some of the results due to Bell and Mason on a near-ring N admitting a derivation D , and we will show that the body of evidence on prime near-rings with derivations have the behavior of the ring. Our purpose in this work is to explore further this ring like behavior. Also, we show that under appropriate additional hypothesis a near-ring must be a commutative ring.
