The present study attempts to indirectly determine if a neuronal cannabinoid (CB1) receptor mediates the intraocular pressure (IOP) reduction effects of arachidonoyl ethanolamide (AEA), its R-alpha-isopropyl analog, and the non-classical cannabinoid, CP-55,940. A series of these cannabinoids were dissolved in an aqueous 10-20%(More)
Degeneration of articular cartilage in osteoarthritis is a serious medical problem. We have isolated a population of cells from the connective tissue of mammals termed mesenchymal stem cells (MSCs) for their apparent unlimited growth potential and their ability to differentiate into several phenotypes of the mesodermal lineage, including cartilage and bone.(More)
A series of anandamide-type compounds were synthesized and studied for their effect on the intraocular pressure (IOP) of normotensive pigmented rabbits. Each test compound was dissolved in an aqueous 2-hydroxypropyl-beta-cyclodextrin solution and administered (31.25 - 62.5 micrograms) unilaterally to the eye. The most promising anandamides caused a(More)
Delta9-tetrahydrocannabinol (THC) is the main psychoactive constituent of Cannabis sativa L. and its therapeutic effects are currently under intensive study. However, THC has a very low aqueous solubility (1-2 microg/mL), which restricts its use as a pharmaceutical. The present study demonstrates that THC forms a drug-cyclodextrin complex in an aqueous(More)
Limited research indicates positive affective change following acute bouts of exercise, but whether this improved affect among younger subjects may be generalized to older individuals is not known. The present study, then, examined the effects of a single bout of physical activity among older participants. 16 trained women (Mage = 64.5 +/- 7.6 yr.)(More)
The leading cause of irreversible blindness is glaucoma, a disease normally characterized by the development of ocular hypertension and consequent damage to the optic nerve at its point of retinal attachment. This results in a narrowing of the visual field, and eventually results in blindness. A number of drugs are available to lower intraocular pressure(More)
PURPOSE Earlier studies have suggested that the intraocular pressure (IOP) effects of topical arachidonylethanolamide (AEA) are mediated through its fatty acid metabolite, rather than through AEA, per se. The purpose of this study was to investigate whether the topical anandamides AEA and arachidonyl propionitrileamide (APN) decrease IOP when their(More)
Low-density lipoproteins (LDLs) are known to be internalized by the cell through receptor-mediated mechanisms. There is evidence that LDLs may be taken up avidly by tumor cells to provide cholesterol for the synthesis of cell membranes. Thus, the possibility exists that LDLs may provide an ideal vehicle for the transport of boron to tumor cells for boron(More)
Arachidonylethanolamide (AEA) was the first anandamide to be identified as an endogenous ligand for the cannabinoid receptor of porcine brain. Since cannabinoids have shown some value in the reduction of ocular hypertension, the title compound was evaluated in normotensive rabbits as a possible topically applied agent for reducing intraocular pressure. AEA(More)
