1. Synthesis and Production of Sweet-Tasting Protein in E. coli and Purification by Amylose Resin

F. Mansouri

Volume 22, Issue 2 , Spring 2011, Pages 105-110

  A sweet water-soluble protein that reminds stable over wide ranges of temperature and pH, Brazzein has various applications. Its tastes like cane sugar but have no calories. However, the extraction of brazzein from its natural source is expensive and not applicable. In this study we used recombinant ...  Read More

2. Association of CCR2 Gene but not CCR5 Gene Polymorphisms with Alzheimer’s Disease

S.M. Mohaddes Ardebili

Volume 22, Issue 2 , Spring 2011, Pages 111-116

  Chemokines participate in the regulation of immune and inflammatory responses by interacting with their specific receptors on related immune and inflammatory cells such as B-lymphocytes, T-lymphocytes and antigen-presenting cells. Chemokines and their receptors are therefore considered to mediate inflammation ...  Read More

3. Refolding of Lysozyme Upon Interaction with ?-Cyclodextrin

G. Rezaei Behbehani

Volume 22, Issue 2 , Spring 2011, Pages 117-120

  Effects of ?-cyclodextrin, ?CD, on refolding of lysozyme was investigated at pH 12 employing isothermal titration calorimetry (ITC) at 300K in 30mM Tris buffer solution. ?CD was employed as an anti-aggregation agent and the heats obtained for lysozyme+?CD interactions are reported and analyzed in terms ...  Read More

4. Template Synthesis of Un-Symmetrical Tetradentate Schiff Base Complexes of Ni(II), Co(II), Zn(II) and X-ray Structure of Ni(II) Complex

M. Lashanizadegan

Volume 22, Issue 2 , Spring 2011, Pages 121-121

  Metal complexes, ML (M=Ni, Cu, Co and Zn) of unsymmetrical tetradentate schiff base have been synthesized by the template reaction of the half-units N-(1-hydroxy-2-acetonaphthone)-1-amino-2-phenyleneimine)(HL1) with 2-Pyrroleca-rbaldehyde. The complexes have been characterized by elemental analysis, ...  Read More

5. Early-Miocene Gastropods from Khavich Area, South of Sirjan, (Kerman, Iran): Biostratigraphy, Paleogeography and Paleoecology

M.J. Hasani

Volume 22, Issue 2 , Spring 2011, Pages 125-133

  A total of 12 species of marine gastropods, among which two taxa are new, is reported for the first time from the Miocene deposits of Khavich section, south of Sirjan, Kerman. Gastropods assemblage in Khavich area indicates deposition in shallow, warm ramp-type carbonate platform. The Miocene and even ...  Read More

6. Occurrence of Prehnite, Pumpellyite and Garnet in Biotite from Granitic Rocks of the Canadian Appalachians: A Mineral Chemistry Study Using Electron Microprobe

A.A. T. Shabani

Volume 22, Issue 2 , Spring 2011, Pages 135-142

  A particular feature of biotite grains from some of the Canadian Appalachian granitic rocks is the presence of lenses of Ca-Al silicates developed along cleavage planes. These from the more to less common are prehnite, pumpellyite and grandite garnet, an intermediate composition between andradite and ...  Read More

7. Kinematics of the Dena Fault and Its Relation to Deep-Seated Transverse Faults in Zagros Fold-Thrust Belt, Iran

A. Yassaghi

Volume 22, Issue 2 , Spring 2011, Pages 143-151

  The NNW-trending Dena Fault, with 140 km length, cuts the major structures of Zagros Fold-Thrust Belt in Borujen region. The fault has divided the region in two zones, in which different structural, andmorphological features as well assedimentation and seismtectonic characteristics have developed. This ...  Read More

8. Lower Bounds of Copson Type for Hausdorff Matrices on Weighted Sequence Spaces

R. Lashkaripour

Volume 22, Issue 2 , Spring 2011, Pages 153-157

  Let = be a non-negative matrix. Denote by the supremum of those , satisfying the following inequality: where , , and also is increasing, non-negative sequence of real numbers. If we used instead of The purpose of this paper is to establish a Hardy type formula for , where is Hausdorff ...  Read More

9. Generalized Baer-Invariant of a Pair of Groups and the Direct Limit

M.R. Rismanchian

Volume 22, Issue 2 , Spring 2011, Pages 159-164

  In this paper we introduce the concept of generalized Baer-invariant of a pair of groups with respect to two varieties ? and ? of groups. We give some inequalities for the generalized Baer-invariant of a pair of finite groups, when ? is considered to be the Schur-Baer variety. Further, we present a sufficient ...  Read More

10. An Entanglement Study of Superposition of Qutrit Spin-Coherent States

M. Jafarpour

Volume 22, Issue 2 , Spring 2011, Pages 165-169

  Considering generalized concurrence as the criterion of entanglement, we study entanglement properties of superposition of two qutrit coherent states, as a function of their amplitudes. These states may attain maximum entanglement or no entanglement at all, depending on the choice of the parameters involved. ...  Read More

11. Entanglement of an Atom and Its Spontaneous Emission Fields via Spontaneously Generated Coherence

M. Sahrai

Volume 22, Issue 2 , Spring 2011, Pages 171-176

  The entanglement between a ?-type three-level atom and its spontaneous emission fields is investigated. The effect of spontaneously generated coherence (SGC) on entanglement between the atom and its spontaneous emission fields is then discussed. We find that in the presence of SGC the entanglement between ...  Read More
