Geroprotective properties of neuroprotective and neurotrophic peptides
Objective: to elucidate whether cerebrolysin contains peptide fragments that promote geroprotection.Material and methods. The peptide composition of cerebrolysin underwent a comprehensive mass spectrometric analysis, followed by a systemic biological ...

Selank effects on morphine-induced analgesia in vivo experiments
Background. The endogenous opioid system is involved in neuroadaptation produced by exogenous opioids. Synthesized on the basis of the regulatory peptide tuftsin, the anxiolytic selank inhibits the activity of enkephalin-degrading enzymes, increasing the

Enkephalin convertase, an enkephalin-synthesizing carboxypeptidase present in adrenal medulla chromaffin granules, has also been detected in brain and pituitary. To determine whether these three carboxypeptidase activities represent the same enzyme, we purified and characterized enkephalin convertase from adrenal medulla, whole brain, and whole ...

The organisation of spinoparabrachial neurons in the mouse [PDF]
The anterolateral tract (ALT), which originates from neurons in lamina I and the deep dorsal horn, represents a major ascending output through which nociceptive information is transmitted to brain areas involved in pain perception.

RELEASE OF VASOPRESSIN BY ENKEPHALIN [PDF]
Leu‐enkephalin, its stable analogue [D‐Ala2‐D‐Leu5]‐enkephalin and the C‐fragment of lipotropin (β endorphin) injected intravenously in the rat produced anti‐diuretic responses which were inhibited reversibly by naloxone. It was shown for Leu‐enkephalin that injection into the cerebral ventricles was at least ten times more effective than intravenous ...

Modulation of Neurally Mediated Vasodepression and Bradycardia by Electroacupuncture through Opioids in Nucleus Tractus Solitarius. [PDF]
Stimulation of vagal afferent endings with intravenous phenylbiguanide (PBG) causes both bradycardia and vasodepression, simulating neurally mediated syncope.

The Opioid System in Temporal Lobe Epilepsy: Functional Role and Therapeutic Potential
Temporal lobe epilepsy is considered to be one of the most common and severe forms of focal epilepsies. Patients often develop cognitive deficits and emotional blunting along the progression of the disease.

Afferent Neuronal Control of Type-I Gonadotropin Releasing Hormone Neurons in the Human. [PDF]
Understanding the regulation of the human menstrual cycle represents an important ultimate challenge of reproductive neuroendocrine research. However, direct translation of information from laboratory animal experiments to the human is often complicated ...
