We investigated the therapeutic effects of l-homocarnosine against inflammation in a rat model of cerebral ischemia-reperfusion injury. Rats were grouped into control, middle cerebral artery occlusion (MCAO), 0.5 mM l-homocarnosine + MCAO, and 1 mM l-homocarnosine + MCAO treatment groups. Superoxide
We recently improved an in vitro ischemic model, using PC12 neuronal cultures exposed to oxygen-glucose deprivation (OGD) for 3 hr in a special device, followed by 18 hr of reoxygenation. The cell death induced in this ischemic model was evaluated by a series of markers: lactate dehydrogenase (LDH)
The development of neuroprotective drugs against ischemic insults is hampered by the lack of pharmacological in vitro models. We developed an ischemic model using PC12 cell cultures exposed to oxygen-glucose-deprivation (OGD) followed by reoxygenation (18 hr) under regular atmospheric oxygen level.
The protective effects of carnosine and related compounds on isolated rat heart were studied under experimental ischemia. The ability of carnosine to suppress significantly the development of ischemic reperfusion contracture and to support the restoration of the contractile force during reperfusion
1. Carnosine, anserine, and homocarnosine are endogenous dipeptides concentrated in brain and muscle whose biological functions remain in doubt. 2. We have tested the hypothesis that these compounds function as endogenous protective substances against molecular and cellular damage from free
Intracellular pH (pH(i)) is an important modulator of cardiac function. Because it is readily influenced by metabolic processes, pH(i) is controlled physiologically. Classical models of intracellular pH regulation comprise acid/base transport proteins expressed in the sarcolemma, acting in concert
