Biochem Biophys Res Commun
. 1994 Oct;
204(1):142-9.
PMID: 7945352
We have investigated sonication-, osmotic shock-, and A23187-induced calcium and horseradish peroxidase release from phosphatidylcholine liposomes. We report that sonication and osmotic shock both cause release of liposome-entrapped horseradish peroxidase...

PMID: 7794418
A purine nucleotide analog, 2'-O-(4-benzoylbenzoyl)guanosine cyclic 3',5'-monophosphate (BBcGMP), was synthesized from 4-benzoylbenzoic acid and cGMP. BBcGMP was found to inhibit several types of cyclic nucleotide phosphodiesterases (PDEs) at low concentrations....

PMID: 7958552
This investigation was conducted to determine the comparative effect of structurally diverse peroxisome proliferators (PP) on the two-dimensional protein pattern of rat liver whole homogenates. Perfluoro-n-decanoic acid (PFDA), perfluoro-n-octanoic acid...

PMID: 8188470
Purpose: To determine whether a new cyclic GMP analog, 2'-O-(4-benzoyl)benzoylguanosine 3',5' cyclic monophosphate (BB-cGMP), significantly reduces intraocular pressure in either normotensive or hypertensive eyes of rabbits. Methods: Intraocular pressure of...

. 1988 Dec;
85(24):9806-10.
PMID: 2462253
Low concentrations of cGMP evoked reversible single-channel currents in patches excised from liposomes that contained purified bovine opsin. Two elementary conductances, of 32 and 17 pS, were observed in the...
