Adrenomedullin: Potential in physiology and pathophysiology

Life Sciences, 2000
Adrenomedullin (ADM), a 52-amino acid ringed-structure peptide with C-terminal amidation, was originally isolated from human pheochromocytoma. ADM mediates vasodilatory and natriuretic properties through the second messenger cyclic adenosine 3',5'-monophosphate (cAMP), nitric oxide and the renal prostaglandin system.

Physiological mechanisms underlying long-term potentiation

Trends in Neurosciences, 1988
Abstract In 1949, D. O. Hebb suggested a synaptic modification for learning and memory that occurs as a consequence of coincidence between pre- and post-synaptic activity 1 . This concept has gained wide acceptance and is often used, in its original or modified form, in neuronal net models dealing with learning and memory 2 .

Melanopsin: photoreceptors, physiology and potential

Current Opinion in Physiology, 2018
The discovery of melanopsin-expressing photosensitive retinal ganglion cells (pRGCs) has led to a fundamental change in our understanding of retinal light detection. pRGCs perform a broad range of non-visual functions — most notably mediating circadian entrainment to the environmental light/dark cycle.

Chlorpromazine: A potential physiological teratogen

Experientia, 1977
Chlorpromazine, a drug commonly administered as an antiemetic during pregnancy, when administered prenatally to chick embryos, was associated postnatally with a ‘curled toe’ anomaly (ED 50% of 88 μg/egg for the 4-day-embryo).
