Pyloric-gland type adenoma of the gallbladder is formed by proliferation of glands resembling pyloric glands, morphologically. No previous report has described the cellular phenotype and differentiation of pyloric-gland type adenoma of the gallbladder, using CD10 as a marker of proper biliary phenotype. Immunostainings were performed for mucin markers such as MUC5AC, human gastric mucin (HGM) f...

Infantile hypertrophic pyloric stenosis (IHPS): A study of its pathophysiology utilizing the newborn 1 hph-1 mouse model of the disease 2 3 Running Title: Rho-kinase and infantile pyloric stenosis 27 28 29 30 31 Abstract 33 Infantile hypertrophic pyloric stenosis (IHPS) is a common disease of unknown etiology. The 34 tetrahydrobiopterin (BH4)-deficient hph-1 newborn mouse has a similar phenotyp...

OBJECTIVE To assess whether diagnostic imaging of pyloric stenosis has made a difference in rapidity of diagnosis, duration of pre-operative hydration, and length of stay in hospital. DESIGN Chart review of infants with confirmed diagnosis of pyloric stenosis. SETTING Paediatric teaching hospital. SUBJECTS 215 infants with a confirmed diagnosis of pyloric stenosis seen during 1974-7 and 1...

Central-pattern-generating neural circuits function reliably throughout an animal's life, despite constant molecular turnover and environmental perturbations. Fluctuations in temperature pose a problem to the nervous systems of poikilotherms because their body temperature follows the ambient temperature, thus affecting the temperature-dependent dynamics of various subcellular components that co...

INTRODUCTION To compare outcomes from early post-pyloric to gastric feeding in ventilated, critically ill patients in a medical intensive care unit (ICU). METHODS Prospective randomized study. Ventilated patients were randomly assigned to receive enteral feed via a nasogastric or a post-pyloric tube. Post-pyloric tubes were inserted by the bedside nurse and placement was confirmed radiographi...

Alimentary canal of fishes has a great variety of structural Peculiarities which are important in fisheries and biology. The aim of this study was to explain the anatomical and histological aspects of stomach and pyloric caeca in L. aurata, L. abu and M. cephalus (Mugilidae) from the Caspian Sea. Fifteen adult individuals of mugilidae; Liza aurata, L. abu and Mugil cephalus were collected f...

Rhythmic movements are often controlled by systems containing coupled subnetworks whose oscillations are of different frequencies. We show how fast inhibition from the pyloric network interacts with a slow modulatory input to control the frequency of the gastric mill rhythm of the crustacean stomatogastric ganglion. We deduce that the timing of the pyloric input is crucial in determining what a...

We study the crustacean stomatogastric nervous system to gain insight in the interaction of oscillators of different intrinsic frequencies. We show how fast inhibition from the pyloric network interacts with a slow modulatory input to control the frequency of the gastric mill rhythm. We deduce that the timing of the pyloric input is crucial in determining what effect it will have on the frequen...

The two pyloric dilator (PD) neurons are components [along with the anterior burster (AB) neuron] of the pacemaker group of the pyloric network in the stomatogastric ganglion of the spiny lobster Panulirus interruptus. Dopamine (DA) modifies the motor pattern generated by the pyloric network, in part by exciting or inhibiting different neurons. DA inhibits the PD neuron by hyperpolarizing it an...

Fifty-six surgical specimens with various ulcerative intestinal disorders were microscopically investigated for evidence of gastric gland metaplasia. Thiry-one specimens (55-4%) showed pyloric gland metaplasia. Among the 31 patients with pyloric gland metaplasia, five showed true gastric metaplasia, consisting of parietal cells, chief cells, and mucous neck cells. The percentage of true gastric...
