Determination of serum visfatin level in patients with Behcet disease, comparing with normal population

Background: Behcet’s disease is an inflammatory, systemic and chronic disorder with unknown etiology affecting multiple systems of body (1). The cause is not clear but seems to be multifactorial, including immune system dysfunction (humoral and cellular immune defects), endothelial cell dysfunction and genetic predisposition (2). White adipose tissue produces variety of proteins in the name of adipocytokines, with important roles in body metabolism. One of these newly identified secreted adipocytokines is visfatin, which is secreted by the visceral fat and its plasma level increases during the obesity. It has insulinmimetic effects in metabolism of cultured cells and activates the insulin receptor (3). Visfatin stimulates inflammatory cells like monocytes and can induces increasing circulating level of IL-6 in mice. It have been considered as a new proinflammatory adipocytokine (4). Previous studies have evaluated visfatin level in immunologic disorders like rheumatoid arthritis and showed it was significantly higher in comparing to control subjects (4,5,6). There was no evaluation in patients with behcet disease yet. Objectives: We have evaluated visfatin level in patients with behcet disease finding inflammatory role of that in pathogenesis and clinical manifestations of behcet disease. Methods: We have evaluated 40 patients with Behcet’s disease fulfilled the International Study Group Criteria for the Diagnosis of Behc¸et’s Disease (ISG) and 40 healthy subjects from healthy candidates referring to behcet clinic of Shiraz medical university as a referral center for these patients in south Iran. Both groups have been matched for age, body mass index (BMI) and sex. Visfatin was checked in both groups using ELISA Kit. Results: There were no significant difference between cases and controls in mean concentration of visfatin level (P = 0.61). Difference in the visfatin level between patients with active and inactive manifestations of Behcet’s disease approximated to the significant levels (6.13 3.20 and 4.25 2.73, respectively; P = 0.07). Conclusion: In view of our study, we have concluded that visfatin levels may affect the clinical manifestations of BD maybe as a proinfalmmatory marker in pathogenesis and active manifestations of Behcet’s disease although more cases should be included in future works

Root Canal Anatomy of Maxillary and Mandibular Teeth

It is a common knowledge that a comprehensive understanding of the complexity of the internal anatomy of teeth is imperative to ensure successful root canal treatment. The significance of canal anatomy has been emphasized by studies demonstrating that variations in canal geometry before cleaning, shaping, and obturation procedures had a greater effect on the outcome than the techniques themselves. In recent years, significant technological advances for imaging teeth, such as CBCT and micro-CT, respectively, have been introduced. Their noninvasive nature allows to perform in vivo anatomical studies using large populations to address the influence of several variables such as ethnicity, aging, gender, and others, on the root canal anatomy, as well as to evaluate, quantitatively and/or qualitatively, specific and fine anatomical features of a tooth group. The purpose of this chapter is to summarize the morphological aspects of the root canal anatomy published in the literature of all groups of teeth and illustrate with three-dimensional images acquired from micro-CT technology.info:eu-repo/semantics/publishedVersio

Sealability of MTA and calcium hydroxidecontaining sealers

OBJECTIVES: The aim of this study was to evaluate the apical sealability of Fillapex(®), Endo-CPM-Sealer(®) and Sealapex(®). MATERIAL AND METHODS: Ninety-four freshly extracted single-rooted teeth were selected and decoronated. All teeth were radiographed to confirm the existence of a single and straight root canal, which was prepared using Protaper Universal and 2.5% sodium hypochlorite. The teeth were randomly divided in groups of 10 specimens each according to the sealer, and the canals were filled using the single cone technique and one of the sealers. Four additional teeth were used as controls. The teeth were submitted to dye leakage with Rhodamine B for 24 h but using vacuum on the initial 15 min. Thereafter, they were cut longitudinally and the leakage was measured in a linear fashion from apex to crown. Data were analyzed by ANOVA and Tukey's tests at 5% significance level. RESULTS: Fillapex(®) and Sealapex(®) showed significantly less dye leakage than Endo-CPM-Sealer(®) (p<0.05). CONCLUSIONS: It was concluded that Fillapex(®) and Sealapex(®) were able to prevent apical dye leakage differently from Endo-CPM-Sealer(®)

Etiologic Causes of Invasive Fungal Sinusitis among Patients of, University Hospitals in Shiraz, Iran.

Background: This study aimed to determine the causes of invasive fungal sinusitis in patients of Shiraz University hospitals, Iran. Methods: This cross sectional study was conducted during 18 months (from 21 March 2009 till 22 September 2010) in three Shiraz University Medical Hospitals Thirty six patients with sings of invasive fungal sinusitis were enrolled, and tissue samples were investigated for histopathology, culture and antifungal susceptibility test. The laboratory results with host factor and sinus computed tomography scan were evaluated for classification of patients as proven, probable and possible invasive fungal sinusitis. Findings: Thirty five patients have involved with at least one risk factor (immune compromised disease, diabetes mellitus, or use of immune suppressed drugs). Radiological findings of para sinus invasion or necrosis were present in 20 patients. By histopathology, 21 patients was considered as proven, from these 17 samples had positive growth. The culture etiology agents were 4 Candida, 8 Aspergillus, and 5 Mucor. All positive culture samples were “Match”ed with histopathology findings. Significan not association were considered for radiologic finding and histopathology and culture (P < 0.05). From 8 patients with mucormycosis histopathology, 6 suffered from diabetes mellitus. None of the antifungal agents were effective on these three types of infections. Conclusion: Imaging procedures can be used for diagnosis of infection in early stage of complication in high risk patients

Determination of serum visfatin levels in patients with Behcet’s disease: a case–control study

Abstract Aim of the work: Behc¸et’s disease (BD) is an inflammatory, systemic and chronic disorder with unknown etiology affecting multiple systems. Visfatin is a new adipokine with insulinmimetic properties and pro-inflammatory function. The serum visfatin levels were evaluated in BD patients to investigate its role in the pathogenesis and clinical manifestations of the disease. Patients and methods: Forty BD patients were recruited from the Behc¸et’s disease clinic at Shiraz University of Medical Sciences in southern Iran and 40 healthy control subjects of matching age, sex and body mass index (BMI) were also included. Serum visfatin level was measured using ELISA. Results: The 40 BD patients included 16 males and 24 females. Seventeen had active clinical manifestations; 16 with oral ulcer, 5 with genital ulcer, 6 with arthritis and 2 with uveitis. The mean age of the BD patients was 34.95 ± 9.6 years and mean BMI was 23.98 ± 4.44. There were no significant differences between cases (5.05 ± 3.05 ng/ml) and controls (4.72 ± 2.84 ng/ml) in the visfatin level (p = 0.61). The difference in the visfatin level between patients with active and inactive manifestations did not reach statistical significance (6.13 ± 3.20 and 4.25 ± 2.73, respectively; p = 0.07). There was no significant difference according to the gender of the patients or the presence of clinical manifestations

Biological control of Phytophthora drechsleri Tucker, the causal agent of pistachio gummosis, under greenhouse conditions by use of Actinomycetes

Actinomycetes enhance soil fertility and have antagonistic activity against wide range of plant root-pathogens. These microorganisms were isolated from agricultural soils of Kerman as pure cultures. Phytophthora drechsleri Tucker, causes gummosis and root rot of pistachio trees worldwide. From 130 Actinomycetes isolates, 12 inhibited growth of the pathogen of pistachio gummosis in culture plates and four of the most active isolates exhibited biological control of the pathogen under greenhouse conditions. When plants were grown in sterile soil mix and treated both with Actinomycetes and the pathogen, the number of healthy plants increased dramatically and the symptoms on diseased plants were less severe in comparison with seedlings treated with the pathogen alone. From the collected data it was well conclusive that in greenhouse tests, soil applications of Actinomycetes controlled causal agent of root rot of pistachio seedlings. Antifungal activity was of fungicidal type on the pathogen mycelia. From the stand point of biotechnological goals, the results indicate that the active isolates can be investigated for use as biofertilizers, biofungicides and use in future development of recombinant DNA in pistachio trees bearing elevated resistance to gummosis. Field trials of the active isolates are under investigatio
