The transient potassium current (I(A)) plays an important role in shaping the firing properties of pyloric neurons in the stomatogastric ganglion (STG) of the spiny lobster, Panulirus interruptus. The shal gene encodes I(A) in pyloric neurons. However, when we over-expressed the lobster Shal protein by shal RNA injection into the pyloric dilator (PD) neuron, the increased I(A) had somewhat diff...

A 51-year-old male presented with abdominal pain and jaundice. He was subsequently diagnosed with cholestatic jaundice and cholangitis. A side-viewing duodenoscope failed to identify the ampulla of Vater in the second portion of duodenum. A regular gastroscope was used, and an ectopic ampulla of Vater was identified in the pyloric channel.

The stomachs of Cetacea are generally uniform in their anatomy. The stomach of a bottlenose dolphin differs only in size from the stomach of a blue whale. The stomach chambers consist of the forestomach, main stomach, connecting channel and two pyloric stomach compartments. The only known exceptions to this general scheme are some of the river dolphins and the beaked whales. The forestomach is ...

background: there are controversies regarding the usefulness of the pyloric drainage methods after esophagectomy as well as differences among various pyloric drainage techniques. therefore, we compared the outcome of pyloromyotomy, pylorus buginage, and no intervention methods on gastric emptying among patients undergone esophagectomy. materials and methods: in this randomized clinical trial, p...

due to early satiety and indigestion. He had had peptic ulcer disease for several years and had received proton pump inhibitor (PPI) therapy for a prolonged period at another center without satisfactory outcome. Endoscopic examination revealed a narrowed pyloric channel that precluded passage of a scope (●" Fig. 1a). Urea breath test result was negative, proving that previous Helicobacter pylor...

Endoscopic submucosal dissection (ESD) has been widely accepted as a curative treatment for gastric neoplasm. Pyloric stenosis is a chronic complication that can be caused by ESD. The aim of this study is to clarify the risk factors and management for pyloric stenosis. From January 2004 to January 2014, a total of 126 patients who underwent ESD adjacent to pylorus were reviewed retrospectively....

(This section is meant for residents to check their understanding regarding a particular topic) QUESTIONS 1. Discuss the epidemiology of pyloric atresia. 2. Describe the etiology of pyloric atresia. 3. What anomalies are associated with pyloric atresia? 4. Discuss the genetics of pyloric atresia. 5. How can pyloric atresia be antenatally diag-nosed? 6. What are clinical features of pyloric atre...

Cardiac sac network activity (cycle period tens of seconds to minutes) has long been known to alter pyloric network activity (cycle period approximately 1 s), but these effects have not been quantified. Some pyloric muscles extract cardiac sac timed variations in pyloric motor neuron firing, and consequently produce cardiac sac timed movements even though no cardiac sac neurons innervate them. ...

Thymol is the most common molecule in thyme and has been proposed as an oral alternative to antibiotics in the feed of pigs and broilers. The knowledge of the in vivo physiological effects of thymol on tissues is limited, particularly its impact on the gastric mucosa, where it is primarily absorbed when it is orally supplied. In this study, thymol (TH, 50 mg/ kg BW) or a placebo (CO) was introd...

that given here, applies the term pyloric canal to the passage through the pyloric sphincter in X-ray photographs of the stomach (fig. 4) and in the description of the movements of the stomach. Most radiologists still use the terms pyloric antrum or pre-pyloric segment for what is anatomically the pyloric canal, though Shanks (1938) uses the terms pyloric canal and pylorus as synonymous, statin...
