1. Application of Molecular DNA Markers (STRs) in Molecular Diagnosis of Down Syndrome in Iran
Volume 15, Issue 2 , Spring 2004

Abstract
  Down syndrome is one of the most common causes of mental retardation observed in approximately 1/700 live birth. The use of two or more STR markers related to chromosome 21 facilitates the diagnosis of Down syndrome within about six hours from the collection of the samples. This is the first study has ...  Read More

3. Anthocyanin Pigments of Siahe Sardasht Grapes
Volume 15, Issue 2 , Spring 2004

Abstract
  The anthocyanins of Siahe Sardasht variety (Vitis vinifera L. var. S.S.) were extracted from freezed samples and were purified by adsorption on cation-exchange resin column. Individual pigments were separated by TLC on cellulose plates. Monomeric anthocyanin content that was determined by pH-differential, ...  Read More

4. Isolation and Identification of a Sulfide/Sulfoxide Monooxygenase Gene from a Newly Isolated Rhodococcus Sp. Strain FMF
Volume 15, Issue 2 , Spring 2004

Abstract
  Rhodococcus FMF is a gram-positive bacterium isolated for the first time from soil samples of Tabriz refinery in Iran. This microorganism is able to catabolize dibenzothiophene to 2-hydroxybiphenyl and inorganic sulfur without the destruction of carbon-carbon bonds. Three structural genes, dszA, dszB, ...  Read More

5. Effects of Recombinant Human Erythropoietin (rHuEpo) on the Blood Cells and Hematopoiesis in Spleen of Rats
Volume 15, Issue 2 , Spring 2004

Abstract
  Recombinant human erythropoietin is a glycoprotein hormone that stimulates erythropoiesis. In clonogenic assays of hematopoietic progenitors, high concen-trations of erythropoietin (Epo) increase CFU-E and diminish the number of granulocytes formed per culture plate. Fetal progenitors are more sensitive ...  Read More

6. Synthesis of Some New 1-[2-(alkylthio-1-benzyl-5-imidazolyl) carbonyl]-4-[3-(isopropylamino)-2-pyridyl] piperazines as Anti-HIV
Volume 15, Issue 2 , Spring 2004

Abstract
  A few analogues of atevirdine or 1-[(5-methoxyindol-2-yl) carbonyl]-4-[3- (ethylamino)-2-pyridyl] piperazine – an anti-HIV belonging to non-nucleoside reverse transcriptase inhibitors were synthesized and evaluated for anti-HIV activity. Replacement of indolyl moiety with 2-alkylthio-1-benzyl-5-imidazolyl ...  Read More

7. Preparation, Characterisation and Antimicrobial Activities of Some Novel Nitriles and Imidazolines
Volume 15, Issue 2 , Spring 2004

Abstract
  Reaction between 5-methyl-3-aminoisoxazole and ?-acetamidophenylsulpho-nylchloride yielded compound 1. Hydrolysis of compound 1 gave a starting compound 4-methoxybenzal-?-5-methyl isoxazol-3-yl-sulphonamido aniline 2. The compound 2 on condensation with different aldehydes and potassium cyanide yielded ...  Read More

8. A Rapid and Practical Method for Deprotection of 1,1-Diacetates Catalyzed by Zirconium Sulfate Tetrahydrate-Silica Gel
Volume 15, Issue 2 , Spring 2004

Abstract
  A simple and efficient procedure for converting a variety of 1,1-diacetates into the corresponding aldehydes was developed. The methodology has been done with zirconium sulfate tetrahydrate-silica gel as catalyst. The temperature plays an important role in these reactions. The phenolic acetate function ...  Read More

9. Synthesis of Some 4-Thiazolidinone Derivatives as Antitubercular Agents
Volume 15, Issue 2 , Spring 2004

Abstract
  Substituted Schiff's bases 2a-o prepared by the treatment of 2-amino-4-(?-methoxyiminocarbomethoxymethyl)-thiazole 1 with different aromatic aldehydes, on cyclocondensation with mercaptoaceticacid and mercaptopropionicacid in dry benzene furnished desired thiazolidinones of type 3a-o and 4a-j, respectively. ...  Read More

10. Amygdaloidal and other Cavity Filling Zeolites of Kuh-e-Aradeh, Central Iran
Volume 15, Issue 2 , Spring 2004

Abstract
  Amygdaloidal, cavity- and fracture-filling zeolites in Eocene volcanic rocks from the Kuh-e-Aradeh of southern Kahrizak, in the northernmost part of Central Iran have been studied in some detail by optical, chemical analysis, SEM, and XRD techniques. The zeolites identified, in order of their relative ...  Read More

11. On C0-Group of Linear Operators
Volume 15, Issue 2 , Spring 2004

Abstract
  In this paper we consider C0-group of unitary operators on a Hilbert C*-module E. In particular we show that if A?L(E) be a C*-algebra including K(E) and ?t a C0-group of *-automorphisms on A, such that there is x?E with =1 and ?t (?x,x) = ?x,x t?R, then there is a C0-group ut of unitaries in L(E) such ...  Read More

12. On Two-parameter Dynamical Systems and Applications
Volume 15, Issue 2 , Spring 2004

Abstract
  In this note some useful properties of strongly continuous two-parameter semigroups of operators are studied, an exponential formula for two-parameter semigroups of operators on Banach spaces is obtained and some applied examples of two-parameter dynamical systems are discussed  Read More

13. Theory of Nonlinear s-Polarized Phonon-Polaritons in Multilayered Structures
Volume 15, Issue 2 , Spring 2004

Abstract
  A theory is presented for the dispersion relations of the nonlinear phonon-polaritons arising when phonons are coupled to the electromagnetic waves in multilayered structures of nonlinear materials. The calculations are applied to a multilayered structure consisting of a thin film surrounded by semi-infinite ...  Read More
