3. Evidence for the Essential Arginine and Histidine Residues in Catalytic Activity of Glucose 6-Phosphate Dehydrogenase from Streptomyces aureofaciens
Volume 16, Issue 1 , Winter 2005

  Glucose 6-phosphate dehydrogenase (G6PD) was purified from Streptomyces aureofaciens and inactivated with butanedione and diethylpyrocarbonate. Incubation of the enzyme with butanedione resulted in a rapid activity loss (80%) within 5 min, followed by a slow phase using a molar ratio to enzyme concentration ...  Read More

5. Purification of Saccharomyces cerevisiae eIF4E/eIF4G/Pab1p Complex with Capped mRNA
Volume 16, Issue 1 , Winter 2005

  Protein synthesis is one of the most complex cellular processes, involving numerous translation components that interact in multiple sequential steps. The most complex stage in protein synthesis is the initiation process. The basal set of factors required for translation initiation has been determined, ...  Read More

6. Synthesis of some New Thiosemicarbazide and 1,3,4-Thiadiazole Heterocycles Bearing Benzo[b]Thiophene Nucleus as a Potent Antitubercular and Antimicrobial Agents
Volume 16, Issue 1 , Winter 2005

  Reaction of 2-hydrazinocarbonyl-3-chloro-5-phenoxy-benzo[b] thiophene with different substituted phenyl isothiocyanate gave N-substituted arylthiosemi-carbazide derivatives (1a-h). 1,3,4-Thiadiazole derivatives (2a-h) were prepared by the cyclization of arylthiosemicarbazides (1a-h) with concentrated ...  Read More

7. -Solid Lithium Perchlorate, a Highly Efficient and Chemoselective Catalyst for the Acetalyzation of Aldehydes
Volume 16, Issue 1 , Winter 2005

  -A simple, efficient, and general method has been developed for the chemoselective acetalization of aldehydes with 1,3-propanediol, 1,2-ethanediol and trimethyl orthoformate in the presence of solid lithium perchlorate under solvent-free conditions. Both cyclic and acyclic acetals of aldehydes were obtained ...  Read More

8. Magmatic and Metamorphic Fluids in Pegmatite Development: Evidence from Borujerd Complex, Iran
Volume 16, Issue 1 , Winter 2005

  The Borujerd complex of western Iran is composed of intrusions and their surrounding contact aureole, with, pegmatites and quartz veins. Pegmatites differ in mineralogy, origin and age, and two groups can be distinguished. The Older Pegmatites (about 120 Ma age) intruded contact metamorphic rocks from ...  Read More

10. Some Probability Inequalities for Quadratic Forms of Negatively Dependent Subgaussian Random Variables
Volume 16, Issue 1 , Winter 2005

  In this paper, we obtain the upper exponential bounds for the tail probabilities of the quadratic forms for negatively dependent subgaussian random variables. In particular the law of iterated logarithm for quadratic forms of independent subgaussian random variables is generalized to the case of negatively ...  Read More

11. Maximal Inequalities for Associated Random Variables
Volume 16, Issue 1 , Winter 2005

  In a celebrated work by Shao [13] several inequalities for negatively associated random variables were proved. In this paper we obtain some maximal inequalities for associated random variables. Also we establish a maximal inequality for demimartingales which generalizes and improves the result of Christofides ...  Read More

12. Hypercentral Constituent Quark Model and Isospin for the Baryon Static Properties
Volume 16, Issue 1 , Winter 2005

  So far the static properties of hadrons have been introduced in various models. The static properties of hadrons (charge radius, magnetic moment, etc.) are useful for understanding the quark structure of hadron. In this work we have introduced the hypercentral constituent quark and isospin dependent ...  Read More
