1. PURIFICATION AND PROPERTIES OF AN EXTRACELLULAR PROTEASE PRODUCED BY PENICIUIUM EXPANSUM
Volume 6, Issue 3 , Summer 1995

Abstract
  Penicilliurn expamum grown in a medium with rice husk as a carbon source produced an extracellular protease. The protease enzyme was isolated from culture broth by fractionation with acetone and column chromatography on Sephadex G- 100 and DEAE A-50. The protease enzyme was purified about 17.47 fold, ...  Read More

2. POLYPHENOL OXIDASE ACTIVITY AND DIFFERENTIATION OF RHIZOMORPH IN ARMILLARIA MELLEA (VAML. EX. FR.) KARST
Volume 6, Issue 3 , Summer 1995

Abstract
  Polyphenol oxidase (PPO) activity varied in differentiation from hyphae to rhizomorph and croute in A. mellea. In undifferentiated hyphae there was not any PPO activity, while croute showed the highest activity. Electrophoresis in the presence of SDS allows the detection of intensive enzyme forms ...  Read More

4. INTERACTION OF DOXORUBICIN WITH DNA-HMG1 COMPLEX
Volume 6, Issue 3 , Summer 1995

Abstract
  In this study, the interaction of the anthracycline antibiotic doxorubicin with DNA-HMG 1 complex was investigated employing UV/VIS spectroscopy, thermal denaturation and DNA cellulose chromatography techniques. The results indicated that the binding of doxorubicin to the protein reduces its Tm in ...  Read More

5. PREPARATION AND CHARACTERIZATION OF [Ni (MAP) ] ; H- MAP = 2- (METHYLAMINO) PYRIDINE H. Aghabozorg* and H. H. Monfared
Volume 6, Issue 3 , Summer 1995

Abstract
  We have recently synthesized [Ni (MAP) ] complex [H-MAP= 2- (methylamino) pyridine]. 2- (Methy1amino)pyridine reacts with MeLi in THF and generates the lithium salt (Li-MAP). Further reaction of NiCl with two equivalent of this ligand in THF leads to the formation of a dark red solution. Analytical ...  Read More

6. SYNTHESIS OF A SPECIAL TYPE OF ZEOLITE FROM ANALCIME FAMILY WITH TRIETHANOLAMINE AND ITS CHARACTERIZATION WITH XRD, FTIR AND SEM
Volume 6, Issue 3 , Summer 1995

Abstract
  A type of zeolite from the analcime family was prepared by using triethanolamine, silica gel and sodium aluminate. The average particle size was around 24 µm. FTIR, XRD and SEM results approved the type of zeolite which was formed  Read More

7. SYNTHESIS OF 4,4'-BIS-PYRIMIDINES AND SOME RELATED BIS-FUSED PYRIMIDINES
Volume 6, Issue 3 , Summer 1995

Abstract
  2,2'-Disubstitutedamino-4-4'-bis-pyrimidines (3a-m) have been prepared by linking 2,4-dichloro-6-methyl-5-nitropyrimidine (1) with several diamines and subsequent reaction with suitable amines. Some of these compounds (3c and 3j) which were reduced catalitically, on treatment with nitrous acid, urea ...  Read More

8. LITHIUM PERCHLORATE MEDIATED AMINATION REACTION OF ALDEHYDES: A NOVEL METHOD FOR SYNTHESIS OF N, N-DIALKYL-p-SILYLATED AMINES*
Volume 6, Issue 3 , Summer 1995

Abstract
  P-Silylated N,N-dialkyl amines (5) were easily synthesized in good to excellent yield from aldehydes (1), trimethylsilyldialkylamines (2), and trimethylsilylmethylmagnesium chloride (4) in the presence of 5 M lithium perchlorate solution in diethyl ether. The reaction Of (2) with aldehyde proceeded ...  Read More

9. SELENIUM HETEROCYCLE XL II [1]. SYNTHESES OF SUBSTITUTED THIAZOLO, SELENAZOLO AND 1,2,3-SELENADIAZOLOINDOLES
Volume 6, Issue 3 , Summer 1995

Abstract
  Reaction of compound 1 with thiobenzarnide or substituted selenobenzamides afforded substituted pyrrolobenzothiazole or selenazoles (2) respectively. Selenium dioxide oxidation of the semicarbazone 4 with selenium dioxide gave 6- benzenesulfonyl- 4,5-dihydro-pynolo [3,2-el benzoselenadiazole (5).  Read More

12. HELICITY AND PLANAR AMPLITUDES IN PION-PROTON SCATTERING AT 6.0 GeV/c
Volume 6, Issue 3 , Summer 1995

Abstract
  In addition to optimal conditions, invariant laws of Lorentz, parity and time reversal are imposed to find the relation between observables (spin rotation parameters) and bilinear combination of helicity amplitudes in pion-proton elastic scattering at 6.0 GeV/c. By normalizing the differential cross-section ...  Read More
