S. Farokhi, A. Ghaffari, H. Haghighi, F. Shams
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2012, DOI: 10.4236/ijcns.2012.529075
Abstract: Web Service Composition provides an opportunity for enterprises to increase the ability to adapt themselves to frequent changes in users' requirements by integrating existing services. Our research has focused on proposing a framework to support dynamic composition and to use both SOAP-based and RESTful Web services simultaneously in composite services. In this paper a framework called \"Model-driven Dynamic Composition of Heterogeneous Service\" (MDCHeS) is introduced. It is elaborated in three different ways; each represents a particular view of the framework: data view, which consists of a Meta model and composition elements as well their relationships; process view, which introduces composition phases and used models in each phase; and component view, which shows an abstract view of the components and their interactions. In order to increase the dynamicity of MDCHeS framework, Model Driven Architecture and proxy based ideas are used.

Tehran University Medical Journal , 2012,
Abstract: Background: Adipokines are proteins which are secreted from the adipose tissue. These groups of proteins are involved in the control of metabolism. Chemerin is one of these adipokines with different proposed biological roles. Serum levels of chemerin have been associated with increased body mass index, insulin resistance, metabolic syndrome, diabetes and cardiovascular diseases. The aim of this study was to assess the association between serum chemerin concentrations and polycystic ovarian syndrome. Methods: This case-control study was performed in Taleghani Hospital in Tehran, Iran during 2011. On 45 patients with polycystic ovarian syndrome and 45 normal individuals as the control group. The participants were selected by easy given sampling method. Body mass index, fasting chemerin and serum insulin concentrations were measured by Enzyme-Linked Immunosorbent Assay (ELIZA) method. Fasting serum glucose was measured by the enzyme-calorimetric method and insulin resistance index (HOMA-IR) was measured by the calculation of relevant equation. Data was analyzed using independent t-test and Pearsons correlation coefficient by SPSS version 18. Results: Serum chemerin, insulin, and glucose concentrations were significantly higher in patients with polycystic ovarian syndrome than the control group. There was no significant correlation between body mass index, serum levels of insulin, glucose, HOMA-IR, or chemerin in cases and controls. Conclusion: This study showed that serum chemerin levels increase in polycystic ovarian syndrome. The findings also suggest that changes in chemerin serum levels could be considered as a criterion for polycystic ovarian syndrome.

Tehran University Medical Journal , 2008,
Abstract: Background: Helicobacter pylori (Hp) infection often occurs in childhood and adolescence, with the frequency increasing with age. Hp infection is associated with insufficient hygiene, overcrowding and low socioeconomic status. Although declining in developed countries, children in the developing countries continue to have a high prevalence of Hp infection. As the association of Hp infection with chronic abdominal pain is not ubiquitously accepted, in this study we investigate the significance of endoscopic finding associated with Hp infection in children with abdominal tenderness.Methods: This cross-sectional study included 1,665 healthy children, aged 6 to 12 years, in whom Hp infection was evaluated using the IgG anti-H. pylori test. Hp-positive children with epigastric tenderness underwent upper gastrointestinal (GI) endoscopy. Urease activity of gastric mucosal biopsies was measured. The presence and density of Hp organisms, the presence of follicular gastritis, and the nature of inflammation and gastritis activity were assessed by histologic examination.Results: Of 1665 children, 429 (26%) subjects (51% girls, 49% boys) were seropositive for H. pylori. There was a significant association between Hp infection and older age (p<0.001) and male/female ratio (p<0.05). Epigastric tenderness was detected in 39 children (1%), 29 of whom underwent upper GI endoscopy. Nodular gastritis with antral erythema was the most common endoscopic finding (26/29; 89.7%). Histological findings revealed that, in all cases with endoscopic nodularity, lymphoid follicles were present. Bacterial density was low in 13 (44.8%), moderate in 14 (48.2%) and high in 2 (7%) subjects.Conclusion: The findings of the present study demonstrated that antral nodularity is the most common feature in children with Hp infection and epigastric tenderness was significantly associated with histological findings of lymphoid follicles.

MR Mehrasbi,B Haghighi,M Shariat,S Naseri
Iranian Journal of Public Health , 2003,
Abstract: Biodegradation of petroleum hydrocarbons (20 g/kg dw soil) was investigated in 3 media, differing in the kind of petroleum fractions. In the laboratory experiments, during 5 months, the activities of petroleum hydrocarbon-degrading microorganisms and dehydrogenase activity of soil was determined. Gas chromatographic analysis showed the biological decontaminations for gas oil, kerosene and synthetic mixture (gas oil, kerosene and furnace oil) are 60 %, 36 % and 55 %, respectively. Dehydrogenase activity which was assessed by TTC technique, correlated significantly positive with the numbers of microorganisms. The Spearman rank correlation coefficients(r) in contaminated soils with gas oil, kerosene and synthetic mixture were 0.79, 0.80 and 0.69, respectively.

Journal of Dentistry , 2013,
Abstract: Statement of Problem: Carpal tunnel syndrome (CTS) is an important cause of work disability. There is controversy over the relation between carpal tunnel syndrome and occupation. The aim of this study was to assess the relationship between the time-span of practicing dentistry and the role of dominant hands in the development of carpal tunnel syndrome.Materials and Method: In this descriptive cross sectional study, 40 dentists and dental students (15 women and 25 men) undertook the electroneuro-diagnostic test in both hands by an electromyogram (EMG) and they were also evaluated in terms of self- reported clinical symptoms.Results: 17.5% of participants were diagnosed to have decreased nerve conduction velocity while10% had reported clinical symptoms of CTS. Both dominant and non-dominant hands were involved. Within cases who were diagnosed as having median nerve neuropathy, 87.5% worked more than 20 hours per week. 57% had 17-23 years of dental practice experience and 14.2% of cases had10-16 years of practice in dentistry.Conclusion: The high rate of CTS symptoms, in both dominant and non-dominant hand among dental practitioners with more years of dental practice, indicates a prequisite for particular attention, then sufficient education on the major risk factors causing this problem. Early diagnosis of these symptoms may improve the future management of the disease.

Pakistan Journal of Biological Sciences , 2008,
Abstract: The nucleotide sequences of Serine-Rich Entamoeba histolytica Protein (SREHP) gene have already exhibited stable and significant polymorphism in the gene studies. Serine-rich protein is also present and polymorphic in Entamoeba dispar which called SREDP. The polymorphism of the Serine-Rich Entamoeba dispar Protein (SREDP) gene among 8 isolates obtained from Iranian cyst carriers were analyzed by a nested PCR-RFLP followed by sequencing of the PCR products. From those isolates, six distinct DNA patterns were observed after PCR-RFLP of the nested PCR, whereas sequencing showed 8 different patterns among the isolates. The results demonstrate an extensive genetic variability among Iranian E. dispar isolates. The repeat-containing region of the SREDP was found extensively polymorphic in size, number and order of repeat units. Genetic diversity of Iranian E. dispar isolates based on the SREDP was more polymorphic in comparison of Serine-Rich Entamoeba histolytica Protein (SREHP) of the E. histolytica isolates as well as were different from a few known SREDP genes.

Asian Journal of Plant Sciences , 2009,
Abstract: This study was conducted to evaluate seed performance under controlled condition and main aim is to show the effects of NaCl, polyethylene glycol (PEG)-8000, temperature (20, 25 and 30°C) and their interactions on Seed Germination (SG) and Seedling Growth (SDG) of a single rice (Oryza sativa) cultivar which is the name of Kalat. It was obtained from one field harvested in 2008. Seeds were treated with the iso-osmotic concentrations of NaCl or PEG (0, -0.2, -0.4, -0.6 and -0.8 MPa) and exposed to the three temperatures (Namely, 20, 25 and 30°C) for 10 days. There were significant solution types (NaCl or PEG)xtemperaturexosmotic potentials interactions (p<0.05) on the FG, the Germination Rate (GR), the Radicle Length (RL), the Hypocotyl Length (HL), the Seedling Dry Weight (SDW) and the Fresh Weight (FW) indicating that the rice seeds responded differently to salt, drought and temperature changes. The highest values of germination parameters were obtained with no osmotic potential (0 MPa) and increases in osmotic potential either by NaCl or PEG inhibited germination indices. The results indicated that the reduction of germination characteristics was much greater for the PEG induced stress compared to the NaCl induced stress at all osmotic and all thermal levels. In addition, the rice seeds exhibited strong effect of change in temperature on germination characteristics. The deleterious effect of NaCl and PEG was more pronounced at 20 and 30°C compared to 25°C. The examined rice cultivar was more tolerant of NaCl salinity and water stress stimulated by the PEG in the germination stage than in the seedling developmental phase.

Journal of Research in Medical Sciences , 2003,
Abstract: ntroduction: In this study, the effect of stress management training on glycemic control has been investigated in type 1 diabetic patients. Methods: The participants were 60 type 1 diabetic patients (Aged 16-30). 30 Subjects attended in 3-month stress management training classes during which the prescribed insulin remained constant, but the other 30 one's did not. HbA1c from all patients were measured before and after the intervention. Besides, in order to assess the ways of coping, a questionnaire was completed by every patient and the scores were compared between two groups. Results: Trained patients showed significantly improved ways of coping. HbA1c changed from 11.7 ± 2.9 and 10.9±2.1 before training to 8.5 ± 1.7 and 10.3±2.1 after intervention in trained and control groups respectively and the changes were significant in case group (p = 0.000). In addition, the difference between HbA1c of two groups was statistically significant at the end of the study ( p = 0.001). Discussion: Results show a clinically significant beneficial effect of stress management training on glycemic control among type 1 diabetic patients. It is recommended to consider this type of trainings an addition to the treatment program in type 1 diabetic patients.

Journal of Research in Medical Sciences , 2004,
Abstract: Background: Anticardiolipin antibody(aCL)has been recognized as a marker for increased risk of Cerebral Vein Thrombosis (CVT). However, there are only rare reports on CVT associated with other antibodies against different phospholipids such as phosphatidyl inositol, phosphatidyl serine, phosphatidic acid and beta 2 glycoprotein I. In this study, we studied the presence of these antiphospholipid antibodies (aPL), demographic and clinical characteristics in 30 patients with CVT. Methods: After diagnosis of CVT in 30 patients with MRI, we measured the titer of aCL and aPL (IgM and IgG) in all cases. The titers of IgG and IgM type of aPL and aCL were estimated in the sera. Results: Anticardiolipin antibody was solely detected in 20% (n=6) and aCL and other aPL in 23.3% ( n=7) of patients, indicating one patient positive for other aPL but not for aCL (non-aCL). Although the aPL positive group did not differ from the aPL-negative group from the stand point of clinical and demographic characteristics, yet seizure, infarct, superficial veins and sinus involvement and the use of OCP were seen more frequently in aPL-positive group Conclusion: Our findings suggest that in addition to aCL, other antiphospholipid antibodies may be an associated condition that plays a role in the pathogenesis of CVT. The presence of aPL in CVT patients is probably associated with more superficial sinus or veins involvement and as a result death rate was lower in aPL- positive group. Further investigations are necessary to establish this hypothesis. Keywords: Cerebral Vein Thrombosis, antiphospholipid antibody, anticardiolipin
