the aim of this study was to prepare liposomes of acyclovir (acy) by thin layer evaporation (tle) and reverse phase evaporation (rev) methods. twenty-seven batches of liposomes from each method were prepared using technique of three variables at three levels (33) factorial design. drug/lipid (molar ratio), hydration volume and hydration time were considered three independent variables in tle me...

BACKGROUND Reductions in detrusor shortening velocity and detrusor contractility have been observed in association with aging. The reasons for these changes are unclear. METHODS We examined the isometric and isotonic responses of detrusor, taken from the bladder body, to adenosine 5'-triphosphate (ATP), noradrenaline (NA), serotonin, and acetylcholine (Ach) in vitro, using bladders from young...

In this article, structural characteristics of amorphous mono-, di-, and tri-substituted esters cellulose have been studied. These were synthesized under homogenous conditions using anhydrides various aliphatic acids. The specific gravity the highly substituted samples was measured by a pycnometric method in aqueous medium. To calculate molar, Van der Waals, free volumes, as well packing coeffi...

Clostripain is rapidly and selectively inactivated by the chloromethyl ketone derived from cr-N-tosyl-L-lysine (TLCK) with an apparent second order rate constant of 8.7 X lo4 M-I set-i at pH 6.5. Alkylation by TLCK occurs only with catalytically active enzyme, the rate of which is considerably retarded by the competitive inhibitors, oc-Ntosyl-L-homoarginine methyl ester and benzamidine. In cont...

A systematic study of the effect of composition on the thermo-physical properties of the binary mixtures of 1-methyl-3-pentyl imidazolium hexafluorophosphate [MPI][PF(6)] with poly(ethylene glycol) (PEG) [M(w) = 400] is presented. The excess molar volume, refractive index deviation, viscosity deviation, and surface tension deviation values were calculated from these experimental density, ρ, ref...
