[ 1 ] - Does Repeated Methamphetamine Exposure at Different Regimens Cause Parkinsonian-Like Behavior in Rats?

Methamphetamine (MA), a highly addictive psychostimulant, produces long-lasting neurotoxic effects well proven in nigrostriatal dopaminergic neurons. Considering the similarities between pathological profile of MA neurotoxicity and Parkinson's disease (PD), some reports show that previous MA abusers will be at greater risk of PD-like motor deficits. To answer the question if repeated MA exposur...

[ 3 ] - اثر ضدالتهابی اسانس حاصل از Eucalyptus globulus Labill. و تأثیر آن بر مسیر NF-ĸB

التهاب یکی از واکنش‌های دفاعی بدن در برابر میکروارگانیسم‌ها و عوامل حساسیت‌زا است. مسیر NF-Κb (Nuclear factor kappa-light-chain-enhancer of activated B cells) یک جزء ضروری از پاسخ‌های التهابی دخیل در تعدادی از بیماری‌های دستگاه تنفسی مانند آسم و بیماری انسداد مزمن ریوی (COPD) است. در طب سنتی، گیاه Eucalyptus globulus Labill. از تیره Myrtaceae به شکل استنشاقی برای بیماری‌های عفونی و التهابی دستگ...

[ 4 ] - Actors of necroptosis scenario in cell\'s scene

Necroptosis, as a novel concept, has been recently introduced in scientific literature. Much of our knowledge about necroptosis comes from ligation of tumor necrosis factor-α to its receptor, TNF receptor 1. Receptor-interacting protein kinase 1, receptor-interacting protein kinase 3 and its substrate, the pseudokinase mixed lineage kinase domain-like protein, have been comprehensively st...

[ 5 ] - Role of Orexin-A receptors within the Locus Coeruleus in the antinociception induced by microinjection of carbachol into the lateral hypothalamus

Introduction: Previous studies have shown that stimulation of lateral hypothalamus (LH) produces antinociception. Orexin-A (OXA) receptor is strongly expressed in the nucleus locus coeruleus (LC) and orexinergic fibers densely project from LH to LC. In this study, we assessed the role of LC and its OXA receptors in antinociceptive response induced by LH chemical stimulation in the rat. Meth...

[ 6 ] - Caspase inhibition in neuroinflammation induced by soluble β amyloid monomer, protects cells from abnormal survival and proliferation, via attenuation of NFқB activity

Introduction: Evidence suggests that neuronal apoptosis in neurodegenerative diseases is correlated with inflammatory reactions. The beneficial or detrimental role of apoptosis in neuroinflammation is unclear. Elucidating this question may be helpful in management of neurodegenerative diseases. Since TNF-α is able to induce apoptosis as well as increased viability of the cells by activation ...

[ 7 ] - Role of nitric oxide and Jun N-terminal kinase in the development of dark neurons in the dorsal horn of the spinal cord following induction of inflammatory pain

Introduction: Dark neurons which their morphological characteristics are consistent with those of cells undergoing apoptosis, are generated as an acute or delayed consequence of several pathological situations. The present study was designed to evaluate whether inflammatory pain regarding the role of NO and JNK lead to the formation of dark neurons in the dorsal horn of the lumbar spinal cor...

[ 8 ] - Study on the possible similar mechanism of ultra low dose-induced hyperalgesia and development of tolerance to analgesia in male rats: an study based on the role of Gs signaling pathway

Introduction: Ultra low dose (ULD) morphine induces hyperalgesia which is mediated by excitatory Gscoupled opioid receptors. This study was designed to investigate the development of tolerance to hyperalgesic effect of morphine. Also we attempt to seek possible similarity, in view of Gs proteins, between hyperalgesic effect of ULD and hyperalgesic effect after tolerance to HD. Method: Male ...

[ 9 ] - The role of ATP-dependent K+ channels in antinociception, tolerance and morphine dependence

Tolerance and dependence are two main problems that have limited morphine administration as an analgesic drug and they might be as a result of changes in the number and affinity of receptors, dysfunction of adenylate cyclase, impaired coupling between activated µ receptor and K+ channels, and changes in the K+ and Ca2+ channels. There are several reports concerning the role of some of these...

[ 10 ] - Mitochondrial Complex I Is an Essential Player in LPS-Induced Preconditioning in Differentiated PC12 Cells

Preconditioning (PC) as a protective strategy against noxious insults can decline cell death and apoptosis. It has been approved that mitochondria play a key role in PC mechanism. The critical role of complex I (CI) in oxidative phosphorylation machinery and intracellular ROS production, particularly in the brain, accentuates its possible role in PC-induced neuroprotection. Here, differentiated...

[ 12 ] - Comparison of Rat Primary Midbrain Neurons Cultured in DMEM/F12 and Neurobasal Mediums

Introduction: Midbrain dopaminergic neurons are involved in various brain functions, including motor behavior, reinforcement, motivation, learning, and cognition. Primary dopaminergic neurons and also several lines of these cells are extensively used in cell culture studies. Primary dopaminergic neurons prepared from rodents have been cultured in both DMEM/F12 and neurobasal mediums in several ...
