Involvement of the endocannabinoid system in retinal damage after high intraocular pressure-induced ischemia in rats.
PURPOSE To evaluate whether high intraocular pressure (IOP)-induced ischemia is associated with modifications in the retinal endocannabinoid metabolism and to ascertain whether drugs that interfereExpand

Anandamide Hydrolysis by Human Cells in Culture and Brain*
Anandamide (arachidonylethanolamide; AnNH) has important neuromodulatory and immunomodulatory activities. This lipid is rapidly taken up and hydrolyzed to arachidonate and ethanolamine in manyExpand

Resveratrol prevents apoptosis in K562 cells by inhibiting lipoxygenase and cyclooxygenase activity.
The natural polyphenolic compound resveratrol (trans-3,4', 5-trihydroxystilbene) is shown to prevent apoptosis (programmed cell death) induced in human erythroleukemia K562 cells by hydrogen peroxideExpand

Inhibition of copper amine oxidase by haloamines: a killer product mechanism.
The observation that the alkylamines 2-Br-ethylamine and 2-C1-ethylamine and 1,2-diaminoethane, the shortest diamine, are irreversible inhibitors of several copper amine oxidases led to theExpand

Kinetics of ultraweak light emission from human erythroleukemia K562 cells upon electroporation.
Electroporation involves the application of an electric pulse that creates transient aqueous channels (electropores) across the lipid bilayer membranes. Here, we describe an instrument set upExpand

Opposite Effects of Ca2+ and GTP Binding on Tissue Transglutaminase Tertiary Structure*
Tissue transglutaminase (tTG) belongs to a class of enzymes that catalyze a cross-linking reaction between proteins or peptides. The protein activity is known to be finely tuned by Ca2+ and GTPExpand
