In the stomatogastric nervous system of the crab, Cancer borealis, a set of 4 serotonergic/cholinergic proprioceptive neurons, called gastropyloric receptor (GPR) cells, have effects on the pyloric motor pattern. In a semi-intact foregut preparation, the GPR cells are not activated by movements of the pyloric filter; instead they respond to the slower movements of the gastric mill (Katz et al.,...

The patient was a 56-year-old woman who had experienced epigastralgia and dorsal pain several times over the last 20 years. She was admitted for a diagnosis of acute cholecystitis, and severe intra- and extrahepatic bile duct dilatation with inner air density was noted. No papilla of Vater was present in the descending duodenum, and 2 small holes were present in the pyloric ring. Bile excretion...

The effects of the nitric oxide donor nitroglycerin on gastric emptying and antropyloroduodenal motility were evaluated in nine healthy male subjects (ages 19-36 yr). Antropyloroduodenal pressures were recorded with a manometric assembly that had nine side holes spanning the antrum and proximal duodenum and a pyloric sleeve sensor; gastric emptying was quantified scintigraphically. In each subj...

In the lobster Homarus, the 2 identified PS neurons have a strong suppressive modulatory effect on the activity of the pyloric network in the STG (Cazalets et al., 1990). In the present paper, we consider the effects of PS on individual pyloric neurons isolated from their partners in the network by cell photoinactivation and synaptic blockade. Three types of PS action are described: (1) a trans...

Prenatal diagnosis of junctional epidermolysis bullosa associated with pyloric atresia was carried out in a couple at risk. Their two previous children had died during the first months of life of the same disorder despite surgery for the pyloric abnormality. Ultrastructural study of fetal skin biopsies obtained at 18 weeks' gestation showed dermal-epidermal separation at the lamina lucida level...

Kimberly J. Kolkhorst, DO Jeffrey Gill, MD, University of South Florida, Department of Gastroenterology, Tampa, Florida We report the case of a 62-year-old female with a history migraines and non-steroidal anti-inflammatory drug (NSAID) use who presented to the emergency department with epigastric abdominal pain associated with intermittent nausea and vomiting for two months. Initial esophagoga...

BACKGROUND AND OBJECTIVE Daidzein is an isoflavone abundant in soybeans, kudzu root and red clover, which have been widely studied for its therapeutic potential. The present study was designed to evaluate the effects of daidzein on alveolar bone loss and internal microstructures of bone in a rat model of experimental periodontitis by assessing morphological data obtained from micro-computed tom...

Pyloric stenosis is defined as an obstruction to gastric emptying due to any cause situated above .he biliary ampulla. This article is concerned with the clinical features, metabolic disorder, assessment and treatment of patients with pyloric stenosis; anatomical narrowing of the pyloric canal without delay in gastric emptying is not considered. In adults, symptoms due to the underlying lesion ...

Which features of network output are well preserved during growth of the nervous system and across different preparations of the same size? To address this issue, we characterized the pyloric rhythms generated by the stomatogastric nervous systems of 99 adult and 12 juvenile lobsters (Homarus americanus). Anatomical studies of single pyloric network neurons and of the whole stomatogastric gangl...
