this study seeks to examine how a company can select the best intermediary for its marketing channels with minimum of criteria and time. a theoretical framework is proposed based on the most important tasks of intermediary and the criteria to measure them. there are four basic tasks and thirty criteria in three independent levels. subsequently, an exploratory case study in iranian food industry...

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...

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...

The ingestion of caustic soda is frequently a source complications. Esophageal stenosis remains among them the most frequent complication and by far formidable. Pyloric rare following soda. We report through this clinical case, cicatricial pyloric after associated with esophagus having caused vomiting onset severe malnutrition. diagnosis was confirmed oeso-gastro-duodenal transit (OGDT) child u...

Recent theoretical and experimental work indicates that neurons tune themselves to maintain target levels of excitation by modulating ion channel expression and synaptic strengths. As a result, functionally equivalent circuits can produce similar activity despite disparate underlying network and cellular properties. To experimentally test the extent to which synaptic and intrinsic conductances ...

The ability of neuropeptides to modulate neural circuit activity is well established, but little is known regarding how the actions of neurally-released peptides are regulated. This issue is being studied in the isolated stomatogastric nervous system (STNS) of decapod crustaceans. The STNS is a small neural system that contains the rhythmically active gastric mill (chewing) and pyloric (filteri...
