Vapour-phase ultraviolet irradiation of hexafluorobenzene in the presence of oxygen slowly yields hexafluoro-3-oxatricyclo[3.2.0.0 2,4 ]hept-6-ene ( 2 ) (10%). The CFCF bond in 2 adds (yields of adducts given) the dienes; cyclopentadiene (74%), fu

Slow-transit constipation (STC) is recognized in children but the etiology is unknown. Abnormalities in substance P (SP), vasoactive intestinal peptide (VIP) and nitric oxide (NO) have been implicated. The density of nerve fibers in circular muscle c

Localization of muscarinic receptors M1R, M2R and M3R in the human colon

Autor: A M, Harrington, C J, Peck, L, Liu, E, Burcher, J M, Hutson, B R, Southwell

Publikováno v: Neurogastroenterology and motility : the official journal of the European Gastrointestinal Motility Society. 22(9)

Muscarinic acetylcholine receptors (MR) are involved in multiple intestinal reflexes. The cellular localization of subtypes of MRs within enteric circuits mediating muscle and mucosal reflexes remains to be demonstrated. This study aimed to localize

Fall in density, but not number of myenteric neurons and circular muscle nerve fibres in guinea-pig colon with ageing

Autor: John M. Hutson, S. D. Samsuria, Bridget R. Southwell, Andrea M. Harrington, Sebastian K. King, C. J. Peck

Publikováno v: Neurogastroenterology and motility : the official journal of the European Gastrointestinal Motility Society. 21(10)

In guinea-pig ileum, ageing has been associated with a decrease in enteric neurons. This study examined guinea-pig colon and measured changes in gut dimensions, neuron size, density and ganglionic area. Changes in motor nerve fibres in the circular m
