Morphological changes in Polyvinyl Butyral (PVB) electrospun nanofibres can be acquired by preparation of PVB spinning solution in different solvents.  Accordingly, three solvents, including ethyl alcohol, n-butanol and isopropanol, with diverse physical properties (e.g. boiling point, density, dipole moment and dielectric constant) were used to prepare PolyVinyl Butyral (PVB) spin...

Conventional treatment of Naja naja oxiana (NNO) envenoming requires large volumes of equine antivenin raised against NNO crude venom. The poor efficiency of this antivenin is assumed to be due to the high molecular weight non-toxic proteins, a strong immunogen, present in the crude venom. These proteins cause depression of antibody formation against the low molecular weight toxic components of...

methods this randomized, crossover study with parallel design was conducted in 45 patients who required maintenance hemodialysis due to end-stage renal failure. four patients with known bleeding disorders, receiving anticoagulant drugs and receiving drugs which could affect heparin activity were excluded. all patients were randomly assigned to receive either enoxaparin sodium (0.7 mg/kg) or sta...

Chiral indium salen complexes are highly active, isoselective catalysts for the ring opening polymerization of racemic lactide. The polymerizations are well controlled and polymers with high molecular weights and low molecular weight distributions are obtained. Preliminary kinetic investigations with the enantiopure complex confirm enantiomorphic site control as the dominant contributor to sele...

Stimulation of chromaffin cells in culture with 1,1-dimethyl-4-phenylpiperazinium (DMPP) or depolarizing concentrations of K+ resulted in a significant secretion of high and low molecular weight enkephalin-like peptides (ELPs) into the culture medium. BioGel P-10 column chromatography was used to characterize the ELPs in chromaffin cell extracts and in culture media before and after stimulation...
