Cardiac arrest is a leading cause of death worldwide. While survival rates following sudden cardiac arrest remain relatively low, recent advancements in patient care have begun to increase the proportion of individuals who survive cardiac arrest. However, many of these individuals subsequently develop physiological and psychiatric conditions that likely result from ongoing neuroinflammation and...

The hepatic vagus branches innervate the liver and serve an important role in liver-brain connection. It appears that brain modulates inflammatory responses by activation of vagal efferent fibers. This activation and subsequent acetylcholine releases from vagus nerve terminals leads to inhibition of inflammatory cytokines through α7 nicotinic acetylcholine receptors (α7nAChRs) which located on ...

background and aims: our previous study has demonstrated that essence of carum copticum reduces contraction activity of ileum in rat. the present study was designed to find out the effects of nonpolar fraction of carum copticum essence (nfcce) on mechanical activity of the isolated ileum in rat. materials and methods: for evaluation of spasmolythic property of fraction, different doses of the s...

The anti-inflammatory effect (AI) induced by peripheral injection of diluted bee venom (dBV) involves activation of spinal cord circuits and is mediated by catecholamine release from adrenal medulla, but the precise neuronal mechanisms involved are not fully understood. In a recent study, we demonstrated that an increase in spinal acetylcholine is involved in mediating the anti-inflammatory eff...

(D-ALa2, NMePhe4, Gly-ol5) encephalin (DAMGO), a selective mu-opioid receptor agonist, has previously been demonstrated to inhibit the cholinergic and the noncholinergic contraction in guinea-pig airways. In contrast, opioids had no inhibitory effect on cholinergic neurotransmission in the upper trachea when stimulated at 8 Hz. We investigated whether DAMGO, a selective mu-opioid receptor agoni...

The cerebral cholinergic system is centrally involved in memory formation. Studies in rodents suggest that cholinergic stimulation may facilitate encoding of new information but may interfere with retrieval. We investigated the effect of cholinergic stimulation on encoding and retrieval of episodic memory in humans. We also tested whether the putative benefit of cholinergic stimulation on memor...

Trihexyphenidyl or Artane® /Parkinane® is an anti-cholinergic drug belonging to the antimuscarinic class. It used in treatment of Parkinson’s disease and widely psychiatry for management extrapyramidal side effects neuroleptics. Its overdose leads a central peripheral anticholinergic syndrome. We report here case seven-year-old Senegalese boy who developed signs intoxication due accidental inge...

The hippocampal circuitry undergoes attentional modulation by the cholinergic medial septum. However, it is unclear how septal activation regulates the spatial properties of hippocampal neurons. We investigated here what is the functional effect of selective-cholinergic and non-selective septal stimulation on septo-hippocampal system. We show for the first time selective activation of cholinerg...
