Congenital hypertrophic pyloric stenosis: a historical, anatomical, pathological and clinical study
… affected by congenital hypertrophy, that the pyloric sphincter itself is not directly affected by the hypertrophy.

Intra-operative Prophylactic Pyloric Balloon Dilatation During Oesophagectomy to Prevent Early Delayed Gastric Emptying
… and may lead to anastomotic leak and pneumonia. Pyloric balloon dilatation (PBD) is a recognised treatment of this complication. Preventative measures such as pyloroplasty, pyloromyotomy and pyloric Botox® injection have all been employed. Recent data however suggest none of these treatments have …

The Nature of the Movements of the Stomach and the Relationship Between Pyloric Motility and Gastric Secretion
The study of the physiology of the stomach has been of great Interest to many investigators. Various theories in the past fifty years have been offered for consideration, some of which yet remain in the theoretical realm, while others have been investigated and verified. Although the functions and …

Translation and transcription are required for endogenous bursting after long term removal of neuromodulators
… inputs to regulate the network activity. The pyloric network of the Cancer borealis stomatogastric ganglion (STG), a rhythmic motor pattern-generating network, requires modulatory inputs to generate this activity. When neuromodulatory inputs are removed, the pyloric network falls silent. …

Determining how stable network oscillations arise from neuronal and synaptic mechanisms
… frequencies in a well-suited model system, the pyloric network of the crab Cancer borealis. The pyloric network has endogenously oscillating 'pacemaker' neurons that inhibit 'follower' neurons, which in turn feed back onto the pacemaker neurons. The focus of this thesis was to determine the …

The control of frequency of a conditional oscillator simultaneously subjected to multiple oscillatory inputs
… stomatogastric ganglion and fast input from the pyloric network of the animal in order to become active. This dissertation studies how the frequency of the gastric mill network is determined when it is simultaneously subjected to two different rhythmic inputs whose timing may be mismatched. We …

Ciclo reprodutivo de Echinaster (Othilia) brasiliensis Müller & Troschel, 1842 (Echinodermata: Asteroidea) na região do Cabo Frio, RJ
… ovaries were not empty for the recovering. The pyloric caeca did not show an annual cycle. An inverse relationship between gonad and pyloric caeca indices was not evident.

Biophysical mechanisms of frequency-dependence and its neuromodulation in neurons in oscillatory networks
… networks around a given frequency. In the pyloric central pattern generator network of the crab Cancer borealis, for example, the pacemaker group pyloric dilator neurons show MPR at a frequency that is correlated with the network frequency. This dissertation uses the crab pyloric CPG to …

Delayed gastric emptying in Ivor Lewis Gastro-oesophagectomy
… divided into: patients receiving intra-operative pyloric botulinum toxin(BOTOX) injections and those without. Comparative analysis against DGE diagnosis was performed. To assess pathophysiology and a novel investigation, 65 patients from 01/12/2017 to 31/12/2019 had blood and breath sampled …

The Effectiveness and Safety of Perioperative Enteral Feeding in Patients with Burn Injuries: a Systematic Review
… systematic review indicate intraoperative post pyloric feeding was safe in the patient groups investigated, since there were nil aspiration events in a combined intervention population of 509 patients. The safety of short fasting (feeds up to 1 hour before surgery) on aspiration events in …

Observation of the Inhibitory Effects on Gastric Secretion and Motility by Atropine-Like Agents
… and motility in innervated and denervated pyloric pouch with gastric fistula dogs. | Studies by Benjamin, Roslere and Grossman (1) using Methanthellne bromide and atropine subcutaneously on histamine stimulated gastric pouches showed that both atropine and Methanthellne bromide inhibited …

Ciclo reprodutivo, gametogênese e desenvolvimento larval de Asterina stellifera (Möbius, 1859) (Echinodermata: Asteroidea) na região de Cabo Frio, RJ
… but the gonad índex (Gl) was higher and the pyloric caeca index (PCI) had less variation in the rocky-shore population. The Gl and PCI had an inverse relationship in both populations, but it was greater in the seagrass-flat population. Environmental factors like hydrodynamics and food …

Characterization of RYamide neuropeptides and their Receptor in the Disease Vector Mosquito, Aedes aegypti
… was found in the central nervous system, midgut, pyloric valve, ileum, rectal papillae, and surprisingly the seminal vesicles. RYamide and its receptor transcript analysis revealed potential regulatory effects of the digestive, reproductive, and excretory systems, along with a neuromodulatory role …

The Effects of Temperature on the Physiology of PHATARIA UNIFASCIALIS : and its Implications for the Species' Distribution in the Gulf of California
… and though both locations had similar indices of pyloric caeca and gonad development, the population at Loreto was distinctly separated by depth into a shallow reproducing population and a deeper feeding population. No such distinct reproducing population was found at the Bay of LA. In addition, …

Significance of variation in concentration of chlorides, acid, and pepsin, in the gastric contents, with particular reference to the control of gastric acidity
… suggestion is made that the gland -cells of the pyloric segment of the stomach represent the principal source of secreted neutral chiorids.

Biologia reprodutiva e estrutura de duas populações de Coscinasterias tenuispina (Lamarck, 1816) (Echinodermata: Asteroidea) na região do Cabo Frio, Rio de Janeiro
… A reciprocal relationship between gonad and pyloric caecum indices was not evident. The continuous spawning suggests that larva are producing throughout the year. Although this continuous spawning, low frequency of small individuals (≤ 3 mm) was recorded in a few months at Prainha and this …

The Gastroduodenal Effects of Buffered Aspirin, Carprofen, And Etodolac in the Healthy Dog and Comparison of the CLOtest® to Histopathologic Evaluation in Identifying the Presence of Helicobacter Spp. in Healthy Dogs
… from each of four gastric regions (cardia, pyloric antrum, greater curvature, and angularis incisura) were obtained endoscopically for use in the CLOtest® and for histopathologic evaluation. Twenty-seven of 30 dogs (90%) were positive for spiral bacteria suspected to be Helicobacter spp. by …
