beta-Endorphin has been shown to possess potent behavioral and antinociceptive activities when administered intraventricularly in cats. On a molar basis, beta-endorphin is 72-96 times more potent than morphine and its actions are blocked by the specific opiate antagonist, naloxone.
Tolerance to beta-endorphin developed acutely in cats if the administration of the peptide was repeated within the first 24 hr. The tolerance was reversed immediately by systemic administration of the serotonin precursor, 5-hydroxytryptophan. It was further shown that 5-hydroxytryptophan potentiates the analgesic effect of the subliminal dose of… (More)
In the last years several computing frameworks based on the ubiquitous and embedding properties have been designed and realized. These systems, characterized by the interconnection of several devices embedded into a micro-environment and interacting among them in order to achieve a common goals, offer new fascinating challenges to face as, for instance, the… (More)
Abstract Immunohistochemical mapping with antibodies against four different types of gonadotropin-releasing hormone (GnRH)-like neuro-peptides has been studied in the brain of adult Rana esculenta. This study confirms the earlier described distribution pattern of the immunoreactive mammaiian GnRH system in the frog brain, as well as revealing that this… (More)
