As a result of a nutrition transition, chronic diseases, including diabetes, have increased in Iran. Nutrition education is a cost-effective method for modifying diet and controlling diabetes. This study aimed to examine the effect of nutrition education using MyPlate recommendations on glycemic and lipid profiles and inflammatory markers in Iranian adults diagnosed with type 2 diabetes. A 12-week randomized clinical trial was conducted on 44 adults aged 30–50 years from Ahvaz, Iran. The participants were divided into education and control groups. The education participants were taught the MyPlate recommendations. Serum levels of fasting blood sugar (FBS), hemoglobin A1c (HbA1c), lipid profiles, and inflammatory markers, including high sensitivity C-reactive protein (hs-CRP), tumor necrosis factor-α, and adiponectin, were measured at the baseline and the end of the study. The results showed that serum levels of FBS (p = 0.014) and HbA1c (p < 0.001) decreased significantly in the education group at the end of the study. The serum level of low-density lipoprotein in the education group declined significantly at the end of the study (p = 0.043). Furthermore, the serum level of hs-CRP (p = 0.005) declined significantly while the level of adiponectin (p = 0.035) increased in the education group at the end of the study. The evidence of this study showed that nutrition education using MyPlate recommendations is an effective method for controlling diabetes complications. A longitudinal analysis with a larger sample size is recommended to confirm the evidence of this study.

Adaptive Control of Pure-feedback Systems with Nonlinear Parameterization via Time-scale Separation

Mehrnoosh Asadi,Heydar Toossian Shandiz 제어·로봇·시스템학회 2017 International Journal of Control, Automation, and Vol.15 No.1

In this paper an adaptive control approach for completely non-affine pure-feedback systems with nonlinearparameterization is proposed. By using the parameter separation technique and coupling it effectively withcombination of backstepping and time scale separation, a fast dynamical equation is derived from the original subsystem,where the solution is sought to approximate the corresponding ideal virtual/actual control input. In thisapproach, since designing state predictor to derive adaptation law of unknown parameters is omitted, our design ismore accurate and less complex. The closed loop stability and the state regulation of nonlinear parameterizationpure-feedback systems are all proved by new theorem in singular perturbation theory. Finally the simulation resultsare provided to demonstrate the effectiveness of the proposed approach.

Temperature and thickness effects on thermal and mechanical stresses of rotating FG-disks

Mehrnoosh Damircheli,Mohammad Azadi 대한기계학회 2011 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.25 No.3

In the present paper, radial and hoop thermal and mechanical stress analysis of a rotating disk made of functionally graded material (FGM) with variable thickness is carried out by using finite element method (FEM). To model the disk by FEM, one-dimensional twodegree elements with three nodes are used. It is assumed that the material properties, such as elastic modulus, Poisson’s ratio and thermal expansion coefficient, are considered to vary using a power law function in the radial direction. The geometrical and boundary conditions are in the shape of two models including thermal stress (model-A) and mechanical stress (model-B). In model-A there exists no pressure in both external and internal layers, and there is a temperature distribution considered as a second order function in the radial direction of the rotating disk. In this case, the temperature dependency of the material properties is considered and a hyperbolic type is assumed for the geometry of the disk. In model-B, there is a constant pressure only on the internal layer and a pressure on the internal layer of the disk without temperature distribution but with different types of surface profiles. Furthermore, the displacements and stresses for various power law indices (N) and angular velocities are calculated and compared to other results in the literature. The effect of varying thicknesses and dependency of material properties on temperature distribution is investigated.

Etemadi, Mehrnoosh,Pourian, Mandana,Shakib, Asyeh,Sabokbar, Tayebeh,Peyghanbari, Vahideh,Shirkoohi, Reza Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.5

Background: Gastric cancer is the second most common cause of cancer death. It has a poor prognosis with only 5-10% of hereditary etiology. If it is diagnosed, it could be helpful for screening the other susceptible members of a family for preventive procedures. Usually it is identified by symptoms such as presence of cancer in different members of family, some special type of pathology such as diffused adenocarcinoma, having younger age and multiple cancer syndromes. Hence, designing a registry program can be a more practical way to screen high risk families for a preventive program. Materials and Methods: Based on the inclusion criteria, a questionnaire was prepared. After pilot on a small number of patients, the actual data was collected from 197 patients and processed in SPSS 16.0. Results: Totally, 11.8% of the patients were younger than 45 years old. Blood type 'A' was dominant and males had a higher risk behavior with higher consumption of unhealthy food. Adenocarcinoma was reported in majority of cases. 21.8% of the patients had the including criteria for familial gastric cancer (FGC). Conclusions: The high percentage of FGC population compared to the other studies have revealed a need to design an infrastructural diagnostic protocol and screening program for patients with FGC, plus preventive program for family members at risk which could be done by a precise survey related to frequency and founder mutations of FGC in a national registry program.

Background: There is a Th1/Th2 cytokine imbalance and expression of IL-17 in patients with brain tumours. We aimed to compare the levels of IL-17A and IL-6 in sera of glioma, meningioma and schwannoma patients as well as in healthy individuals. Materials and Methods: IL-17A and IL-6 levels were measured in sera of 38 glioma, 24 meningioma and 18 schwannoma patients for comparison with 26 healthy controls by commercial ELISA assays. Results: We observed an increase in the IL-17A in 30% of glioma patients while only 4% and 5.5% of meningioma and schwannoma patients and none of the healthy controls showed elevated IL-17A in their sera ($0.29{\pm}0.54$, $0.03{\pm}0.15$ and $0.16{\pm}0.68$ vs. $0.00{\pm}0.00pg/ml$; p=0.01, p=0.01 and p=0.001, respectively). There was also a significant decrease in the level of IL-6 in glioma patients compared to healthy controls ($2.34{\pm}4.35$ vs. $4.67{\pm}4.32pg/ml$; p=0.01). There was a direct correlation between the level of IL-17A and age in glioma patients (p=0.005). Glioma patients over 30 years of age had higher IL-17A and lower IL-6 in their sera compared to the young patients. In addition, a non-significant grade-specific inverse trend between IL-17A and IL-6 was observed in glioma patients, where high-grade gliomas had higher IL-17A and lower IL-6. Conclusions: Our data suggest a Th17 mediated inflammatory response in the pathogenesis of glioma. Moreover, tuning of IL-6 and IL-17A inflammatory cytokines occurs during progression of glioma. IL-17A may be a potential biomarker and/or immunotherapeutic target in glioma cases.

Thermodynamic model for prediction of performance and emission characteristics of SI engine fuelled by gasoline and natural gas with experimental verification

Dashti Mehrnoosh,Hamidi Ali Asghar,Mozafari Ali Asghar 대한기계학회 2012 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.26 No.7

In this study, a thermodynamic cycle simulation of a conventional four-stroke SI engine has been carried out to predict the engine performance and emissions. The first law of thermodynamics has been applied to determine in-cylinder temperature and pressure as a function of crank angle. The Newton-Raphson method was used for the numerical solution of the equations. The non-differential form of equations resulted in the simplicity and ease of the solution to predict the engine performance. Two-zone model for the combustion process simulation has been used and the mass burning rate was predicted by simulating spherical propagation of the flame front. Also, temperature dependence of specific heat capacity has been considered. The performance characteristics including power, indicated specific fuel consumption, and emissions concentration of SI engine using gasoline and CNG fuels have been determined by the model. The results of the present work have been evaluated using corresponding available experimental data of an existing SI engine running on both gasoline and CNG. It has been found that the simulated results show reasonable agreement with the experimental data. Finally, parametric studies have been carried out to evaluate the effects of equivalence ratio, compression ratio and spark timing on the engine performance characteristics in order to show the capability of the model to predict of engine operation.

Akhtari-Zavare, Mehrnoosh,Juni, Muhamad Hanafiah,Ismail, Irmi Zarina,Md Said, Salmiah,Latiff, Latiffah A Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.9

Background: Breast cancer is the most frequently occurring cancer in women and the most common cause of cancer death worldwide. Materials and Methods: A cross-sectional study was carried out among 792 female undergraduate students in public universities in Klang Valley, Malaysia, from January to April 2011. Data were collected using a validated questionnaire developed for this study. Results: The mean age of respondents was $21.7{\pm}1.2$ years. Most of them were single (96.8%), Malay (91.9%) and 150 (19.6%) claimed they had practiced BSE. There was a significant differences between performers and non-performers correlated to age, marital status, check breast by doctor, and being trained about BSE. Performers had lower mean scores for perceived barriers and susceptibility and higher mean score for confidence. Stepwise logistic regression analysis yielded four significant predictor variables. Conclusions: Overall our findings indicate that the practice of BSE while perceived as being important is not frequently practiced among female in Malaysia. Targeted education should be implemented to improve early detection of breast cancer.

Background: In Iran, breast cancer is the most prevalent cancer in women and a major public health problem. Methods: A cross sectional study was carried out to determine knowledge on breast cancer and breast self-examination (BSE) practices of 384 females living in the city of Hamadan, Iran. A purposive sampling method was adopted and data were collected via face-to-face interviews based on a validated questionnaire developed for this study. Results: Among respondents 268 (69.8%) were married and 144 (37.5%) of the respondents reported having a family history of breast cancer. One hundred respondents (26.0%) claimed they practiced BSE. Level of breast cancer knowledge was significantly associated with BSE practice (p=0.000). There was no association with demographic details (p<0.05). Conclusion: The findings showed that Iranian women's knowledge regarding breast cancer and the practice of BSE is inadequate. Targeted education should be implemented to improve early detection of breast cancer.
