-
(Sage Publications, 1993)A method to prevent the loss of enzymatic activity of proteolytic enzymes toward high molecular weight substrates that occurs upon derivatiza tion with monomethoxypoly(ethylene glycol) (mPEG) is described. It is based on ...
-
(Sage Publications, 1998-04-01)In this study, two different strains of five different bacteria were isolated and characterized. Contact angles were measured by a captive-bubble technique. Surface free energies were calculated from the contact angles and ...
-
(Sage Publications, 1998-01-01)We have synthesized and studied a new type of polymeric drugcarrier based on hydrophobically modified bioadhesive graft copolymers. Two different hydrophobic oligomers, an oligo(methyl methacrylate) (oMMA) and a random ...
-
(Sage Publications, 1991)Coarse aqueous sprays of the polymer, poly-α,β-[N(2-hydroxy ethyl)-D,L-aspartamide], (PHEA), containing a covalently bound fluorophore, ethyl carbonyl-6-aminofluorescein, were administered in doses ranging 2.2 through 3.6 ...
-
(Sage Publications, 1992)Pepsin-induced degradation of albumin-crosslinked hydrogels was studied as a function of the degree of albumin incorporation in the network and the concentration of pepsin. The degree of albumin incorporation, which ...
-
(TECHNOMIC PUBLISHING CO., INC., 1996-07-01)Oligomerizations of various amino acid N-carboxyanhydrides (NCAs) were prepared in the presence of L-tyrosine methyl ester (Tyr.Me). Tyr.Me was found to be an efficient initiator to form oligopeptides consisting of L-aspartic ...
-
(TECHNOMIC PUBLISHING CO., INC., 1996-07-01)Some thermally derived proteinoids are known to form hollow microspheres under specific conditions. In this study, oligomers consisting of L-aspartic acid, L-glutamic acid, L-phenylalanine, and L-tyrosine were prepared ...
-
(Sage Publications, 1988)Amorphous water soluble derivatives of cyclodextrins are potent, nontoxic solubilizers of drugs and lipids. Their use as excipients which enable effective oral administration of sex hormones is described. Furthermore, these ...
-
(Sage Publications, 1986-04-01)An in vivo test for the estimation of blood compatibility of pliable sutures coated with the test polymer was developed. An 18 gauge needle was inserted into the peripheral vein of a dog under general anesthesia and a ...
-
(Sage Publications, 1994)To elucidate the degradation mechanism of poly(lactic acid), the decrease in the intrinsic viscosity of poly(D,L-lactide) in a homogeneous water/ acetone solution was investigated. The hydrolysis of poly(D,L-lactic acid) ...
-
(Sage Publications, 1987)Polyurethane films were prepared from toluene diisocyanate (TDI), and poly(propylene-ethylene)glycol without catalyst. These films had a decrease in tensile strength and an increase in ultimate elongation when the TDI ...
-
(Sage Publications, 1987)A collagenous antiadhesive membrane with slow heparin release was tested in animal studies and found to exhibit antiadhesion activity. The antiadhesive membrane was prepared by crosslinking protamine to purified human ...
-
(Sage Publications, 1989)This study describes a series of mechanical tests to determine the correlations between the strength properties of acrylic bone cement with anti biotic additives and the amount of antibiotic released from the cement. ...
-
(Sage Publications, 1993)An oil-in-water emulsion of selectively cytotoxic α-linolenic acid (ALA, C18:3ω3) was stabilized with cholesterol-bearing pullulan (CHP-55-2.1), and the in vivo anticancer effect of the O/W-emulsion was investigated. The ...
-
Antithrombogenic Poly(vinyl chloride) with Heparin- and/or Prostaglandin I2-Immobilized in Hydrogels(Sage Publications, 1989)Poly(vinyl chloride) (PVC) with heparin- and/or prostaglandin I2 (PGI2)- immobilized on crosslinked polyacrylamide hydrogels were prepared by the ad dition of the dry hydrogels to a PVC tetrahydrofuran solution. Immobilized ...
-
(Sage Publications, 1998-04-01)The synthesis, elemental and spectrometric analysis of isoniazid conjugates with polyethylene glycol) (PEG) were obtained. In the first part of the work, acyl isoniazid, hydroxymethyl isoniazid, and modified poly(ethylene ...
-
(Sage Publications, 1989)To provide a macromolecular prodrug of 5-fluorouracil (5FU) with reduced side-effects, an affinity for tumor cells and exhibiting the high antitu mor activity, the covalent attachment of 5FU to chitosan and chitin through ...
-
(Sage Publications, 1990)Microorganisms from activated sludge were immobilized by at tachment to microporous plastic sheets [MPS™]. Biodegradation of phenol was accomplished by pumping a phenol solution through a reactor containing microorganisms ...
-
(Sage Publications, 1988)
-
(Sage Publications, 1992)Chitosan, a polycationic polymer and waste product from the sea food processing industry, is an abundant natural resource that has, as yet, not been fully utilized. Advantages of this polymer include availability, low cost, ...
