background and objectives: many nepeta species have been commonly used in iranian folk medicine as tranquilizer, relaxant, carminative and restorative tonic for nervous and respiratory disorders. inflammation is a problem in many diseases and has an important role in brain function that can cause neurodegenerative disorders. inflamed glial cells can exacerbate neurodegenerative diseases by prod...

objectives: toxoplasma gondii is a coccidian protozoon which forms tissue cyst in different organs of infected intermediate host. the present study was conducted to demonstrate the active form of parasite in different tissues of rat, which was experimentally infected with rh strain of toxoplasma gondii using bioassay method inmice. materials & methods: in the experimental assay, 75 rats an...

introduction: brain injury is an important cause of morbidity and mortality worldwide and so far, there has been no absolute treatment for the damaged brain tissue. using human stem cells with self-assembling scaffolds can be a promising method for treatment of traumatic brain injury. materials and methods: human meningioma stem cells were isolated, cultured and then expanded into in vitro cond...

Alzheimer’s disease (AD) is a progressive neurodegenerative disorder that affects regions of the brain that control cognition, memory, language, speech and awareness to one’s physical surroundings. The pathological initiation and progression of AD is highly complex and its prevalence is on the rise. In his study, Alzheimer's disease was induced with single injection of amyloid-β (Aβ) peptides (...

Microglia is considered the only cell population of mesodermal origin, which comprises 10% of the cells in brain parenchyma. Recent neural stem cell (NSC) studies demonstrate that the brain has regenerative potential. NSCs do not give rise to microglial cells, however indicating that NSCs alone cannot complete the regenetion of the brain. Although the role of microglia is not fully understood, ...

Cerebral dopamine neurotrophic factor (CDNF) and mesencephalic astrocyte-derived (MANF) are involved in neuroprotection mitigating endoplasmic reticulum (ER) stress the brain peripheral organs. In earlier work, an increase histone acetylation, following treatment with epigenetic modulator, valproic acid, was associated induction of CDNF MANF cultured cells rat brain. These findings prompted inv...

Abstract Stroke remains a leading cause of long-term disability in developed countries and the second death worldwide. Recent decades have witnessed substantial progress understanding pathophysiology ischemic stroke treatment stroke-related motor deficit. However, current therapies fail to offer patients satisfactory improvements. Therefore, more effective approach for treating deficit is still...

objectives: crocin, a constituent of saffron and yellow gardenia, possesses anti-nociceptive effects. in the present study, we investigated the effects of intra-fourth ventricle injection of crocin in a rat model of orofacial pain. the contribution of opioid system was assessed using intra-fourth ventricle injection of naloxone, an opioid receptor antagonist. materials and methods: a guide cann...

Abstract The purpose of this work was to develop and evaluate a deep learning approach for automatic rat brain image segmentation magnetic resonance imaging (MRI) images in clinical PET/MR, providing useful tool analyzing studies the pathology progression neurological disease validate new radiotracers therapeutic agents. Rat PET/MR ( N = 56) were collected from system using dedicated small-anim...
