زمینه و هدف: در اکثر نقاط ایران، به­ویژه مناطق مرکزی، جنوب و شمال شرقی، عقرب­زدگی یک مشکل بهداشتی جدی محسوب می­شود. بیشتر این گزش ها، ناشی از عقرب‌های خانواده بوتیده (Buthidae Family) می‌باشد. زهر عقرب دارای ترکیبات فعال بیولوژیک مختلف از جمله سموم عصبی (نروتوکسین) می‌باشد که هر کدام توسط ژن مخصوص به خود کد می‌شوند. هدف از انجام این پژوهش تکثیر cDNA کد کنندة یک نروتوکسین شبه آل...

While curcumin has been reported to provide several health medicinal benefits, its effects on brain, particularly during diseased condition, is known very less. To evaluate the contribution of curcumin against neuropathological implications of Parkinson’s disease, mice were experimented in the present study. Both MPTP (M) and MPTP plus Curcumin (MC) group received 30 mg/Kg body weight MPTP intr...

Nigrostriatal damage is increased in males relative to females. While estrogen is neuroprotective in females, less is known about potential protective effects of testosterone in males. We determined if castration enhances neuronal injury to 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). Castrates or sham-castrated mice were sacrificed 1 week following injection of MPTP (4 × 20 mg/kg) or s...

The mitochondrial permeability transition pore (MPTP) describes an inducible activity that regulates solute exchange between mitochondrial matrix contents and the surrounding cytoplasm, which acutely leads to loss of mitochondrial inner membrane potential but eventually organelle swelling and rupture. Mitochondrial rupture due to prolonged MPTP engagement, which is often the result of ischemic ...

BACKGROUND Mitochondria are critical to cardiac injury during reperfusion as a result of damage sustained during ischemia, including the loss of bcl-2. We asked if bcl-2 depletion not only leads to selective permeation of the outer mitochondrial membrane (MOMP) favoring cytochrome c release and programmed cell death, but also favors opening of the mitochondrial permeability transition pore (MPT...

In addition to their normal physiological role in ATP production and metabolism, mitochondria exhibit a dark side mediated by the opening of a non-specific pore in the inner mitochondrial membrane. This mitochondrial permeability transition pore (MPTP) causes the mitochondria to breakdown rather than synthesize ATP and, if unrestrained, leads to necrotic cell death. The MPTP is opened in respon...

Oxidative stress has been implicated in the etiology of Parkinson's disease (PD) and in the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) animal model of PD. It is known that under conditions of oxidative stress, the transcription factor NF-E2-related factor (Nrf2) binds to antioxidant response element (ARE) to induce antioxidant and phase II detoxification enzymes. To investigate the rol...

Background: Parkinson disease (PD) is a neurodegenerative disorder that has been associated with many factors, including oxidative stress, inflammation, and iron accumulation. The antioxidant, anti-inflammatory, and iron-chelating properties of epigallocatechin gallate (EGCG), a major polyphenol in green tea, may offer protection against PD.Objective: We sought to determine the neurorescue effe...

1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) causes nigrostriatal dopaminergic neurotoxicity and behavioral impairment in rodents, and previous studies suggest that nitric oxide and reactive oxygen species are involved in MPTP-induced neurotoxicity. The present study examines the effect of edaravone (3-methyl-1-phenyl-2-pyrazolin-5-one), a radical scavenger, on MPTP-induced neurotoxicity...
