Noncompetitive N-methyl-D-aspartate (NMDA) receptor antagonists such as phencyclidine are psychotomimetics and disrupt prepulse inhibition (PPI), a measure of sensorimotor gating that is deficient in schizophrenia. Systemically administered competitive NMDA receptor antagonists do not disrupt PPI in rats, leading to speculation that these compounds might have use as neuroprotective agents witho...

BACKGROUND Rats emit 50 kHz ultrasonic vocalizations (USVs) in response to either natural or pharmacological pleasurable stimuli, and these USVs have emerged as a new behavioral measure for investigating the motivational properties of drugs. Earlier studies have indicated that activation of the dopaminergic system is critically involved in 50 kHz USV emissions. However, evidence also exists tha...

OBJECTIVE Axonal degeneration is a main contributor to disability in progressive neurodegenerative diseases in which oxidative stress is often identified as a pathogenic factor. We aim to demonstrate that antioxidants are able to improve axonal degeneration and locomotor deficits in a mouse model of X-adrenoleukodystrophy (X-ALD). METHODS X-ALD is a lethal disease caused by loss of function o...

Vestibular disorders, by inducing significant posturo-locomotor and cognitive disorders, can significantly impair the most basic tasks of everyday life. Their precise diagnosis is essential to implement appropriate therapeutic countermeasures. Monitoring their evolution is also very important to validate or, on the contrary, to adapt the undertaken therapeutic actions. To date, the diagnosis me...

BACKGROUND Sildenafil, a selective phosphodiesterase 5 (PDE5) inhibitor, has recently been reported to influence the antidepressant activity of some antidepressant drugs. The present study was undertaken to investigate the involvement of the nitric oxide/cyclic guanosine 3',5'-monophosphate/PDE5 (NO/cGMP/PDE5) signaling pathway in the antidepressant activity of paroxetine and to assess the inte...

IL-37, a member of the IL-1 family, broadly reduces innate inflammation as well as acquired immunity. Whether the antiinflammatory properties of IL-37 extend to the central nervous system remains unknown, however. In the present study, we subjected mice transgenic for human IL-37 (hIL-37tg) and wild-type (WT) mice to spinal cord contusion injury and then treated them with recombinant human IL-3...

iran’s economy has experienced an average inflation rate of 18.77 percent during the period of 1979-2010. many economists believe that the budget deficits are one of the main determinants of the chronic and relatively high inflation. this paper investigates the relationship between budget deficits and inflation. dynamics of iran’s monetary sector, based on the three cointegration relations i.e....
