Serum levels of cross-linked n-telopeptide of Type i collagen before and after non-surgical periodontal therapy in type 2 diabetic patients with chronic periodontitis
...Show More Authors

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.

Immuno-hematological and biochemical changes in diabetic retinopathy patient`s blood after treatment by Nd-YAG laser
...Show More Authors

Diabetic retinopathy is one of most important complications of diabetes mellitus that can be treated by Nd:YAG laser. Laser is used in ophthalmic practice for photocoagulation and photodisruption. The purpose of this study is to evaluate changes in immunological ,hematological and biochemical values after treatment of diabetic retinopathy by laser. Blood samples from 10 patients suffering from diabetic retinopathy were taken before and after laser treatment to coagulate retina to prevent leakage and hemorraghe to avoid deterioration of vision.In group one (4 patients = 40%), blood tests were done one day after treatment. In group two (6 patients =60%) tests were done 7 days after treatment with laser. The study showed no clear changes in

Serum Trace Elements (Zinc, Copper and Magnesium) Status in Iraqi Patients with Acne Vulgaris :( Case- Controlled Study)
...Show More Authors

Recently on the dermatological fields, the serum levels and the roles of Zn, Cu and Mg have been studied especially in acne vulgaris, but the results were controversial. The aim of the present study is to investigate  a relationship between the severity of acne and the serum levels of zinc (Zn), copper (Cu) and magnesium (Mg) and to demonstrate the status of serum levels of zinc, copper, and magnesium in Iraqi male patients with acne vulgaris and to compare it with those of healthy controls.This case controlled study was conducted in the Department of Dermatology and Venerology and in the Poisoning Consultation Center of Baghdad Teaching Hospital between May 2009 to January 2010. Forty- five male patients with acne vulgaris, their a

Assessment of serum and salivary oxidant and total antioxidant status of patients with recurrent aphthous stomatitis in a sample of Basrah city
...Show More Authors

Background: Recurrent Aphthous Stomatitis (RAS) is the most common painful oral mucosal disease, affecting approximately 20% of the population. RAS presents with a wide spectrum of severity ranging from a minor nuisance to complete debility. Many of factors thought to have been involved in its etiology; that might have at the same time a direct or indirect impact upon oxidant/antioxidant system and trigger free radicals production. The aim of this study was to determine the possible association of oxidant/total antioxidant status and recurrent aphthous stomatitis (RAS). Subjects, materials and methods: The study consisted of thirty patients with recurrent aphthous stomatitis and thirty healthy controls from which saliva and blood samples we

The Rational Use of Collagen in Osteoarthritis: Review article
...Show More Authors

Osteoarthritis is a degenerative disease affecting joints that is chronic and disables the movement of patients with increasing pain and decreasing their quality of life with age. Available treatments are only symptomatic with no cure. Recent methods for managing osteoarthritis involve using pharmacological, non-pharmacological treatments or both for improving physical function in patients and alleviating pain. Clinical trials were conducted to reveal the extent of benefits obtained from different nutraceuticals and food supplements, such as collagen with growing use and fairly good results in the treatment of osteoarthritis. The goal of this study is to review the current information about the rational use of collagen in osteoarthritisKeyw

Magnetic Shielding, Aromaticity, Antiaromaticity and Bonding in the Low‐Lying Electronic States of S <sub>2</sub> N <sub>2</sub>
...Show More Authors

Aromaticity, antiaromaticity and chemical bonding in the ground (S0), first singlet excited (S1) and lowest triplet (T1) electronic states of disulfur dinitride, S2N2, were investigated by analysing the isotropic magnetic shielding, σiso(r), in the space surrounding the molecule for each electronic state. The σiso(r) values were calculated by state-optimized CASSCF/cc-pVTZ wave functions with 22 electrons in 16 orbitals constructed from gauge-including atomic orbitals (GIAOs). The S1 and T1 electronic states were confirmed as 11Au and 13B3u, respectively, through linear response CC3/aug-cc-pVTZ calculations of the vertical excitation energies for eight singlet (S1–S8) and eight triplet (T1–T8) electronic states. The aromaticities of S

Producing Ceramic Water Purifiers Made Of Iraqi Bentonite Type (Bpl1)
...Show More Authors

In this study, ceramic purifier (CP) was produced from a mixture of Iraqi raw materials. This ceramic mixture was prepared using Bentonite as a Clay, Porcelanite as a Silica, and Limestone as a flux. The produced ceramic filter was formed by semi-dry compressing method and was fired at 1200 C?. Physical properties of the produced CP were measured. A hydraulic test rig was constructed to study the hydraulic conductivity of the produced CP. The average hydraulic conductivity of the produced CP was 55 times that of commercial types of ceramic filters. The mineral composition of the produced ceramics was found by X-Ray tests. Tests results showed that all of the produced ceramics filters composed mainly of low Cristobalte and Tridoymite in addi
