[ 8 ] - The effect of hydroalcoholic extract of Ziziphora clinopodioides L. on spatial memory and neuronal density of hippocampal CA1 region in rats with sporadic Alzheimer's disease
Objective: Alzheimer's disease is a neurodegenerative disorder associated with gradual loss of cognitive and memory abilities. It was shown that the hippocampus is one of the first structures in the brain that is affected by the disease. Ziziphora clinopodioides<span style="font-size: mediu...
[ 9 ] - Obestatin inhibits apoptosis and astrogliosis of hippocampal neurons following global cerebral ischemia reperfusion via antioxidant and anti-inflammatory mechanisms
Objective(s): Obestatin is a newly discovered peptide with antioxidant activities in different animal models. Recent studies have shown that Obestatin inhibits apoptosis following cardiac ischemia/reperfusion injury. Brain ischemia/reperfusion induces irreversible damage especially in the hippocampus area. This study aimed at examining the protective impact of Obestati...
[ 10 ] - Effect of Intracerebroventricular Morphine Withdrawal on the Anxiety Behavior in Male Rats Reared in Social Isolation
Aims: Prescription of narcotics has controversial effects on the occurrence of anxiety processes. On the other hand, the social isolation has been caused due to the drug consumption, but its acute and chronic effects on behavioral differences are not obvious in the process of dependency and withdrawal. The present study aimed to investigate effects of acute and chronic intracerebroventricular M...
[ 11 ] - Myelin Protection by Ursolic Acid in Cuprizone-Induced Demyelination in Mice
Neuronal survival in multiple sclerosis (MS) and other demyelinating diseases depends on the preservation of myelin and remyelination of axons. Myelin protection is the main purpose to decrease myelin damage in the central nervous system (CNS). Ursolic acid (UA) as a natural product in apple is suggested to protect neural cells. This study is the first to demonstrate an effect for UA on CNS mye...
