Economic load dispatch is one of the most important problems in power system operation, therefore the aim of this paper is to establish a method to reduce electricity generation costs with a new approach. This method introduces two new constraints called rate of change of frequency (ROCOF) and minimum frequency as the main constraints in economic dispatch in this paper. This approach reduces emission and fuel costs of the power plants as well as transmission line losses. Therefore, this method has also the capability to control frequency in a desirable range. Finally, the proposed method is simulated on a test system. In the simulation, the economic load flow with is solved with spinning reserve, transmission lines loses and generation constraints as well as the two new mentioned constraints, i.e. ROCOF and minimum frequency constraints. Simulation results obtained from the proposed and conventional methods, show advantages of proposed method. ©2008 IEEE.

Plant profilins form a well-known panallergen family responsible for cross-sensitization between plant foods and pollens. We sought to map T and B-cell epitopes on the Iranian Crocus sativus profilin by bioinformatics tools. The predicted peptides are useful for further vaccine development. © 2008 Bentham Science Publishers Ltd.

Glutathione S-transferase is a family of multifunctional detoxification enzymes which are mainly cytosolic that detoxify natural and exogenous toxic compounds by conjugation with glutathione. Glutathione, an endogenous tripeptide, is important as either a reducing agent or a nucleophilic scavenger. This molecule alleviates the chemical toxicity in plants by reaction of glutathione S-transferase, and its conjugates can be transported to vacuole or apoplast. The plant soluble glutathione S-transferases grouped today into seven distinct Phi, Tau, Zeta, Theta, lambda, dehydroascorbate reductase, and tetrachlorohydroquinone dehalogenase classes. In this study, bioinformatics analysis of glutathione S-transferase gene in barley was carried out using Tau-class of barley glutathione S-transferase sequences in NCBI GenBank and isolated sequence. DNA extraction, primer design, PCR, electrophoresis, column purifica-tion, DNA sequencing and analysis by some software led to identify new sequences of Tau-class of glutathione S-transferase from barley, which is similar to Tau GST of the diploid wheat. Comparison of the deduced amino acid sequences of the three barley GST genes showed that they have 99% identity with each other but only 45% identity with the new GST. This sequence was submitted to NCBI GenBank with FI131240 accession number.

Leishmania is associated with a broad spectrum of diseases, ranging from simple cutaneous to invasive visceral leishmaniasis. Here, the sequences of ten cysteine proteases of types A, B and C of Leishmania major were obtained from GeneDB database. Prediction of MHC class I epitopes of these cysteine proteases was performed by NetCTL program version 1.2. In addition, by using BcePred server, different structural properties of the proteins were predicted to find out their potential B cell epitopes. According to this computational analysis, nine regions were predicted as B cell epitopes. The results provide useful information for designing peptide-based vaccines. © 2009 Beijing Genomics Institute.

To investigate the genetic structure of human populations in the South-west region of Iran, mitochondrial first hypervariable DNA sequences were obtained from 50 individuals representing three different ethnic groups from Khuzestan Province. Studied groups were Shushtari Persians and Chahar Lang Bakhtiyaries from Indo-European-speaking populations and Bani Torof Arabs from Semitic-speaking linguistic families. Genetic analysis of mtDNA data showed high similarity of Chahar Lang Bakhtiyaries with other Iranian Indo-European-speaking populations while Shushtaries and Bani Torofs had a closer affinity with Semitic-speaking groups rather than to other Iranian populations. The relationship of Chahar Lang Bakhtiyaries and Bani Torof Arabs with their neighbor populations can be explained by linguistic and geographic proximity. Whereas, the greater similarity of Shushtari Persians with West Asian Arabs is probably according to high gene flow between them. This article represents a preliminary study of three major ethnic groups of South-west Iran which investigates the potential genetic substructure of the region. © 2011 Higher Education Press and Springer-Verlag Berlin Heidelberg.

Glutathione S-transferases are multifunctional proteins involved in diverse intracellular events such as primary and secondary metabolisms, stress metabolism, herbicide detoxification and plant protection against ozone damages, heavy metals and xenobiotics. The plant glutathione S-transferase superfamily have been subdivided into eight classes. Phi, tau, zeta, theta, lambda, dehydroascorbate reductase and tetrachlorohydroquinone dehalogenase classes are soluble and one class is microsomal. Glutathione S-transferases are mostly soluble cytoplasmic enzymes. To date, the crystal structures of over 200 soluble glutathione S-transferases, present in plants, animals and bacteria have been resolved. The structures of glutathione S-transferase influence its function. Phylogenetic analysis suggests that all soluble glutathione S-transferases have arisen from an ancient progenitor gene, through both convergent and divergent pathways. © 2011 Academic Journals.

Ramsey Optimal Growth model is widely used in dynamic macroeconomics. Graduate and undergraduate students have problem in doing with Ramsey Model. In this paper we try to solve Ramsey model using Genetic Algorithm. Genetic Algorithm is a new optimization approach that is widely used in dynamic analysis. It seems that solving optimization problems with GA approach will produce better results than Excel solver.

Plasminogen activator inhibitor type-2 (PAI-2) is a serine protease inhibitor of the fibrinolytic system produced predominantly by the macrophages and monocytes. It has been demonstrated that fibrinolysis regulation has a great importance in the pathogenesis of atherosclerotic plaques. Thus in the current investigation, we sought to determine whether Ser 413/Cys polymorphism (rs6104) of PAI-2 gene could be associated with atherosclerosis and cardiovascular risk factors. Ser 413/Cys polymorphism was determined by PCR-RFLP technique using Mwo I restriction enzyme for 184 men under 50 years of age and 216 women less than 55 years of age who underwent diagnostic coronary angiography. Data on the history of familial myocardial infarction or other heart diseases, hypertension, and smoking habit were collected by a simple questionnaire. Fasting levels of blood sugar, triglycerides, total cholesterol, lowdensity lipoprotein and high-density lipoprotein cholesterol levels were also measured by enzymatic methods. Frequencies of the Ser 413 and Cys 413 alleles were 0.760 and 0.240 in the whole population, respectively. The PAI-2 gene variant analyzed was not significantly associated with either the prevalence of premature CAD or the classical risk factors of CAD development such as diabetes, serum cholesterol, triglycerides, low-density lipoprotein and highdensity lipoprotein cholesterol, body mass index, hypertension, familial history of heart dysfunction or smoking.
