objective(s):acrylamide (acr) has broad applications in different industries. it also forms in food during heating process. oxidative stress has a critical role in acr-induced neurotoxicity in both in vitro and in vivo models; therefore, the aim of the current study was the evaluation of effects of thymoquinone, the main constituent of volatile oil from nigella sativa seeds in acr-induced neuro...

BACKGROUND The C-terminal domain of the heavy chain of tetanus toxin (Hc-TeTx) is a nontoxic peptide with demonstrated in vitro and in vivo neuroprotective effects against striatal dopaminergic damage induced by 1-methyl-4-phenylpyridinium and 6-hydoxydopamine, suggesting its possible therapeutic potential in Parkinson's disease. Methamphetamine, a widely abused psychostimulant, has selective d...

The need for effective treatments for addiction and dependence to the illicit stimulant methamphetamine in primary care settings is increasing, yet no effective medications have been FDA approved to reduce dependence [1]. This is partially attributed to the complex and dynamic neurobiology underlying the various stages of addiction [2]. Therapeutic strategies to treat methamphetamine addiction,...

Introduction: Recent studies demonstrated that cannabidiol had neuroprotective property. Thereis some evidence about effective role of cannabidiol in reducing ischemic damages. It has been reported that infarct size is influenced by various factors after MCAO, including inflammatory factors. The aim of the present study was to evaluate the effect of cannabidiol on infarction volume and correlat...

To clarify the association between oxidative DNA damage and the neurotoxicity of arsenic, the formation of 8-hydroxy-2'-deoxyguanosine (8-OHdG) as an index of oxidative DNA damage in the brain was examined in mice fed with drinking water containing 1 or 2 ppm arsenic, using an HPLC-electrochemical detector and immunohistochemical method. 8-OHdG levels were significantly increased in the brain o...

background: deltamethrin (dm) is a synthetic pyrethroid insecticide that can elicit neurotoxicity, leading to apoptosis. there is accumulating evidence that oleuropein (oe) has anti-apoptotic effect. the purpose of this study was to determine the anti-apoptotic effect of oe pretreatment in the neuronal cells of cerebral cortex. methods: rats were randomly divided into four groups each containin...

We have explored the role of endogenous dopamine in the control of histaminergic neuron activity in mouse brain regions evaluated by changes in tele-methylhistamine (t-MeHA) levels. In vitro, methamphetamine released [(3)H]noradrenaline but failed to release [(3)H]histamine from synaptosomes. In vivo, methamphetamine enhanced t-MeHA levels by about 2-fold with ED(50) values of approximately 1 m...

Rhynchophylline (Rhy) is an active component isolated from species of the genus Uncaria which has been used for the treatment of ailments to the central nervous system in traditional Chinese medicine. Besides acting as a calcium channel blocker, Rhy was also reported to be able to protect against glutamate-induced neuronal death. We thus hypothesize that Rhy may have neuroprotective activity ag...

Methamphetamine use by females of child-bearing age has become a major public health concern in terms of the long-term risk to the exposed fetus. We examined the possibility of enhanced adult neurotoxic potential of the drug in offspring that had been exposed to methamphetamine in utero during gestational days 7 to 18. While basal levels of monoamines were not affected by prenatal exposure to m...
