1. Resposta neuro-imuno-endocrinologica da pele relacionada ao fotoenvelhecimento : avaliação in vitro e clinica de um novo composto como alternativa terapeutica em dermatologia / Skin neuro-immuno-endocrinology response related to photoaging : in vitro and clinical assessment of a new compound as therapeutical alternative in dermatology
O envelhecimento cutâneo é resultado de dois processos independentes, clinica e biologicamente distintos, que afetam a pele simultaneamente. Ao primeiro, conhecido como "relógio biológico", damos o nome de envelhecimento intrínseco, o qual afeta a pele na mesma proporção em que órgãos internos são afetados, como por exemplo, a lenta e irreversível

2. Cholinergic-opioidergic interaction in the central amygdala induces antinociception in the guinea pig
Several studies have demonstrated the involvement of the central nucleus of the amygdala (CEA) in the modulation of defensive behavior and in antinociceptive regulation. In a previous study, we demonstrated the existence of a cholinergic-opioidergic interaction in the CEA, modulating the defensive response of tonic immobility in guinea pigs. In the present s

3. Bacterial lipopolysaccharide induction of leukocyte-derived corticotropin and endorphins.
Previous reports have shown that there is an endogenous opioid component associated with pathophysiological responses to endotoxin. It has been shown that these responses are alleviated by naloxone, a specific opiate antagonist. Results of another study have indicated that leukocytes may mediate some of those responses since leukocyte depletion alleviated th

4. Endorphins may function in heat adaptation.
Administration of the opiate antagonist naloxone to rats after acute or chronic heat exposure precipitates an increase in colonic temperature, an increase in escape attempts, and a decrease in body weight. These changes are accompanied by signs associated with hyperthermia such as salivation, diarrhea, and an abnormal extended posture. Although brain endorph

5. N-acetyl endorphin in rat spermatogonia and primary spermatocytes.
In previous reports modest levels of beta-endorphin have been found by radioimmunoassay in rat testis, and localized by immunofluorescence to the interstitial cells. We have confirmed these previous reports and extended them by showing that the majority of testicular endorphins are acetylated forms, N-acetyl gamma-endorphin, N-acetyl alpha-endorphin, and N-a

10. Increase in plasma beta endorphins precedes vasodepressor syncope.
BACKGROUND--Endogenous opioids have a tonic inhibitory effect on sympathetic tone and have been implicated in the pathophysiology of vasodepressor syncope. Plasma beta endorphin concentrations increase after vasodepressor syncope induced by exercise or by fasting. AIMS--To take frequent samples for plasma beta endorphin estimation during tilt testing, and to

12. Human leukocyte interferon: structural and biological relatedness to adrenocorticotropic hormone and endorphins.
Anti-alpha-corticotropin [anti-ACTH alpha (1-13)](also alpha-melanotropin) and anti-gamma-endorphin antisera neutralized human leukocyte interferon activity but not fibroblast interferon activity. Human leukocyte interferon was not neutralized by anti-human lutenizing hormone (lutropin) or follicle-stimulating hormone (follitropin) antisra. Conversely, antis
