1. Stability of Recombinant Proteins in Escherichia coli: The Effect of Co-Expression of Five Different Chaperone Sets

H. Mirzahoseini

Volume 20, Issue 4 , Autumn 2009

Abstract
  Chaperones are produced by prokaryotic, yeast and higher eukaryotic cells for various purposes. Over-expression of each chaperone or sets of them affect the production level of a recombinant protein in the cell. On the basis of this hypothesis, five different plasmids with 5 different combinations of ...  Read More

2. Comparison between Polyvinyl Pyrrolidone/Na2SO4 Aqueous Two-Phase Systems and Chromatographic Methods for Purification of Recombinant Phenylalanine Dehydrogenase

E. Omidinia

Volume 20, Issue 4 , Autumn 2009

Abstract
  Phenylalanine dehydrogenase (PheDH; EC 1.4.1.20) is an important enzyme of amino acid dehydrogenases family that increasingly used as a valuable biocatalyst in neonatal screening kits and synthesis of L-phenylalanine. The goal of this literature was to find a suitable purification method for recombinant ...  Read More

3. Quantitative Bacterial Micro-Assay for Rapid Diagnosis of Galactosemia: Application in Galactosemia Neonatal Screening

S. Vallian

Volume 20, Issue 4 , Autumn 2009

Abstract
  In the present study a new economic and rapid bacterial micro-assay for simultaneous detection and quantitative measurement of serum galactose was developed. Analysis of the standard curve showed a linearity range for galactose from 2 mg/dL to 180 mg/dL with a regression equation of Y = 0.013X ? 0.083; ...  Read More

4. Synthesis and Anti Cancer Activity of Pyrido[2,3-c]Pyridazine Derivatives

V. Kumar

Volume 20, Issue 4 , Autumn 2009

Abstract
  Cancer is not just one disease, but a large group of almost one hundred diseases. Its two main characteristics are uncontrolled growth of the cells in the human body and the ability of these cells to migrate from the original site and spread to distant sites. If the spread is not controlled, cancer can ...  Read More

5. Geochemistry and Tectonic Setting of Pleistocene Basaltic Lava Flows in the Shahre-Babak Area, NW of Kerman, Iran: Implication for the Evolution of Urumieh- Dokhtar Magmatic Assemblage

S.Z. Hosseini

Volume 20, Issue 4 , Autumn 2009

Abstract
  Pleistocene basaltic lava flows, consisting of trachybasalt and basaltic trachyandesite, cover an area north-northwest of Shahre-Babak in southeastern Iran. The whole rock chemistry indicates that the lavas are dominantly alkaline and mildly calc-alkaline. Variation diagrams of SiO2 with major and trace ...  Read More

6. Cation Exchange Between Piemontite and Garnet in Piemontite-Quartz Schists from Asemi-Gawa Area of Central Shikoku, Sanbagawa Metamorphic Belt, Japan

J. Izadyar

Volume 20, Issue 4 , Autumn 2009

Abstract
  In the Asemi-gawa area of intermediate high-pressure and low-temperature Sanbagawa metamorphic belt in central Shikoku, Japan, piemontite-quartz schists are common in which cation exchange between piemontite and garnet has been studied. Piemontite in contact with garnet usually contains two zones in ...  Read More

7. Optimum Block Size in Separate Block Bootstrap to Estimate the Variance of Sample Mean for Lattice Data

M. Mohammadzadeh

Volume 20, Issue 4 , Autumn 2009

Abstract
  The statistical analysis of spatial data is usually done under Gaussian assumption for the underlying random field model. When this assumption is not satisfied, block bootstrap methods can be used to analyze spatial data. One of the crucial problems in this setting is specifying the block sizes. In this ...  Read More
