Activin A is a member of the transforming growth factor β super family. Because of its extensive clinical usages, its recombinant production is beneficial. In this study, activin A was expressed in E. coli using the pET 21a expression vector. The optimization of the activin A production in E. coli was done by using the response surface methodology (RSM). At this stage, the effect of IPTG and la...

backgrounds and objectives : ganoderic acids are the most valuable secondary metabolites in ganoderma lucidum traditional medicinal mushrooms, which have shown antitumor properties in many studies. however, application of ganoderic acids is limited due to low yield production. recently, it was shown that static liquid culture could be a proven technology for producing ganoderic acids in ganoder...

transcranial magnetic stimulation (tms) has been applied to a growing number of psychiatric disorders as a neurophysiological probe, a primary brain-mapping tool and a candidate treatment. although most investigations have focused on the treatment of major depression, increasing attention has been paid to anxiety disorders. the aim of this study is to long time (for 30 days) effect of repetitiv...

background: tetraploid rainbow trout has a key role in producing infertile triploid fish by indirect method and introducing them in cultivation system. objectives: the purpose of the present study was to determine the optimal heat shock for tetraploidy induction in rainbow trout with emphasis on egg size. methods: the efficiency of different shock temperatures: 28, 30 and 32 °c, durations: 1, 5...

induction of labor is one of the most common procedures during pregnancy. various methods for cervical ripening and labor induction have been described in the obstetrics literature; but the role of corticosteroids in the process of labor is not entirely understood. this study challenged the possible role of corticosteroids in induction of labor by extra-amniotic injection through an inflated in...

This paper presents a parametric low differential order model, suitable for mathematically analysis for Induction Machines with faulty stator. An adaptive Kalman filter is proposed for recursively estimating the states and parameters of continuous–time model with discrete measurements for fault detection ends. Typical motor faults as interturn short circuit and increased winding resistance ...

background: in this study, we examined a new two step induction protocol for improving the differentiation of human umbilical cord blood-derived mesenchymal stem cells into neural progenitor cells. materials and methods: human umbilical cord blood-derived mesenchymal stem cells were first cultured in dulbecco’s modified eagle medium supplemented with 10% fetal bovine serum in a humidified incub...

In this paper, a new method based on genetic-fuzzy algorithm for multi-objective optimization is proposed. This method is successfully applied to several multi-objective optimization problems. Two examples are presented: the first example is the optimization of two nonlinear mathematical functions and the second one is the design of PI controller for control of an induction motor drive supplie...
