antioxidant role of oleuropein on midbrain and dopaminergic neurons of substantia nigra in aged rats
background: oleuropein is a phenolic compound which is present in the olive leaf extract. the purpose of the present study was to investigate the neuroprotective effect of oleuropein as an antioxidant agent on the substantia nigra in aged rats. methods: twenty 18-month-old wistar rats (450-550 g) were randomly divided into control and experimental groups. the experimental group received a daily...
background and objective: parkinson's disease (pd) is characterized by a progressive loss of dopaminergic neurons in substantia nigra. in recent years, there have been interests in the role of the free radical damage in pd. cinnamon and its derivative, cinnamaldehyde acts as powerful antioxidant and anti-inflammatory agents. this research focused on the effects of cinnamon extract and cinn...
In this paper some upper and lower bounds for the greatest eigenvalues of the PI and vertex PI matrices of a graph G are obtained. Those graphs for which these bounds are best possible are characterized.
BACKGROUND AND PURPOSE Traumatic and ischemic brain injury induce plasmalemma permeability and necrosis; however, no studies have examined these aspects of cellular injury in intracerebral hemorrhage models. METHODS In vivo propidium iodide (PI) and YOYO-1 were used to assess plasmalemma damage after collagenase-induced intracerebral hemorrhage in mice. Ex vivo aspartylglutamylvalylaspartic a...
