BACKGROUND: Gastric neuroendocrine tumors(GI-NETs) are rare lesions, usually discovered incidentally during endoscopy. Based on their pathology, there are 4 types of GI-NETs. Type I are multiple small polypoid lesions with central ulceration located in the gastric body or the fundus, associated with atrophic gastritis usually noninvasive and very rarely metastatic. We report on a rare case of a gastric NET arising from the muscularis propria layer of the pyloric ring. CASE REPORT: We present the case of a 65-year old woman with a history of alcoholic cirrhosis, investigated for melena...

Six postglacial lakes were studied along both sides of the Kamchatka central mountain range, Russia. Pairs of local morphotypes of species of Arctic charrs, Salvelinus spp., have previously been described from the southernmost lakes while the fish fauna of the four northernmost lakes was studied here for the first time. Phenotypic data support the division of Kamchatkan lacustrine charrs into two groups according to the number of gill rakers and pyloric caeca, as well as snout-dorsal and snout-ventral distances (MANOVA, P < 0·001)...

We describe the case of a 3-week-old boy with pyloric stenosis who presented for laparoscopic pyloromyotomy in the setting of symptomatic transient neonatal myasthenia gravis. The patient received muscle relaxation with rocuronium, and neuromuscular blockade was successfully reversed with sugammadex with recovery guided by train-of-four monitoring. He was extubated uneventfully without complications. Because sugammadex binds directly to rocuronium rather than interfering with acetylcholine metabolism, it might provide a good option for reversal of neuromuscular blockade in transient neonatal myasthenia gravis...

Yang Zhang, Dirk M Bucher, Farzan Nadim
Axonal conduction velocity can change substantially during ongoing activity, thus modifying spike interval structures and, potentially, temporal coding. We used a biophysical model to unmask mechanisms underlying the history-dependence of conduction. The model replicates activity in the unmyelinated axon of the crustacean stomatogastric pyloric dilator neuron. At the timescale of a single burst, conduction delay has a non-monotonic relationship with instantaneous frequency, which depends on the gating rates of the fast voltage-gated Na(+) current...

Operating on more than a single procedure in a same surgical intervention saves time, anesthesia duration and can increase the overall quality of life by lowering the duration of hospital stay and minimizing patient anxiety. But such interventions require expertise, high surgical performance, and precision in anatomical manipulation. We present a case of an outstanding performance of a unique minimally invasive simultaneous approach of removing a pre-pyloric gastrointestinal stromal tumor (GIST) along with a cholecystectomy by a robot-assisted laparascopic surgical system...

The improvement in feed efficiency is one of the most important subjects in fish culture. The development of feed, in terms of good intake, high growth performance, and high feed efficiency is needed. Squid viscera are one of the candidates for alternative material in improving feed efficiency in fish culture. In the present study, we described the dietary effect of the squid viscera hydrolysate (SVH) on the growth performance of the red sea bream. The addition of SVH to feed caused significant increases in feed intake, fork length, and body weight and produced a marked improvement in feed conversion after 4 weeks of feeding...

This work contributes basic knowledge on larval development of Seriola rivoliana. A histological study describes the development of the digestive tract and accessory glands in S. rivoliana larvae reared under laboratory conditions at 24 °C from hatching to 30 days post-hatching (DPH). At hatching (2.6 ± 0.12 mm), larvae had an undifferentiated digestive tract with a closed straight tube and a large yolk sac with an oil globule. The liver and pancreas were observed at 1 and 2 days, and the mouth and anus opened at day 2...

REVIEW
R Vera, L Díez, E Martín Pérez, J C Plaza, A Sanjuanbenito, A Carrato
Surgical resection is the only potentially curative option in the treatment of pancreatic ductal adenocarcinoma. Preoperative radiological imaging allows to rule out the presence of metastases. Three resectability categories are established based on the radiological findings depending on the degree of contact between the tumor and the blood vessels. Histological confirmation of malignancy is only required in cases of borderline or non-resectable tumors, prior to neoadjuvant treatment initiation. Diagnostic laparoscopy is recommended in the presence of large tumors of the body or tail and in borderline tumors to explore the possibility of resection and to apply treatment with curative intent, as well as in those cases with high level of biomarkers to rule out peritoneal involvement...

In patients with inflammatory bowel disease (IBD), cytomegalovirus (CMV) infections could aggravate the course of IBD but it is difficult to distinguish CMV infection from IBD exacerbation endoscopically. Usually, CMV tends to localize to the colon and other organic involvements were reported very rare in the IBD patients. Herein, we report a case that CMV gastric ulcer complicated with pyloric obstruction in a patient with ulcerative colitis during ganciclovir therapy, which was resolved by surgical gastrojejunostomy with review of literature...

Parasitic disease is among the major causes of health problems in marine mammals. However, little information on parasitic species composition and infection levels in finless porpoises (Neophocaena spp.) is available. In this study, we report the first systematic survey on parasitic infections in the East Asian finless porpoise N. asiaeorientalis sunameri (EAFP) living off the Chinese Yellow/Bohai Sea coast. Using both morphological and molecular methods, 5 parasitic helminths were identified: Campula oblonga in the liver and pancreas; Synthesium seymouri in the pyloric stomach and duodenum ampulla; Anisakis pegreffii in the forestomach, main stomach, and esophagus; Halocercus sp...

Cholecystokinin (CCK) is an important neuro-intestinal peptide hormone produced by the enteroendocrine I-cells in the upper part of small intestine. Protein- and fat-enriched food plays an important role in triggering CCK secretion from the intestine. Carbohydrates stimulate only small amounts of CCK release. The CCK-1 receptor (CCK-1R) is largely localized in the gallbladder, sphincter of Oddi, pancreas, small intestine, gastric mucosa, and pyloric sphincter, where it is responsible for CCK to regulate multiple digestive processes including gallbladder contraction, pancreatic secretion, small intestinal transit, and gastric emptying...

Leptin, a highly conserved adipocyte-derived hormone, plays important roles in a variety of physiological processes, including the control of fat storage and metabolic status which are linked to food intake, energy homeostasis, and reproduction in all vertebrates. In the present study, we hypothesize that leptin is also present in various organs of the fresh water prawns, Macrobrachium rosenbergii. The existence and distribution of a leptin-like peptide in prawn tissues were verified by using Western blotting (WB) and immunohistochemical detection (ID) using primary antibody against human leptin...

Pancreaticobiliary maljunction (PBM) is the anomalous union of the main pancreatic duct and common bile duct outside the Oddi-sphincter, allowing the reflux of pancreatic juice to the gallbladder. There is only limited awareness and understanding of the pathologic correlates of this condition, mostly from Japan; this entity is largely unrecognized in the West. In this study, 76 gallbladders from patients with PBM (64 from Japan; 12 from the United States) were analyzed and contrasted with 66 from non-PBM patients...

Gastric mRNA expression of markers for acid secretion and inflammation and presence of gastric ulceration was studied in naturally Helicobacter suis-infected and non-infected 2-3 months old, 6-8 months old and adult pigs. In H. suis-infected 2-3 months old pigs, IL-8 and IL-1β transcript levels were upregulated in the pyloric gland zone, indicating an innate immune response. A similar response was demonstrated in the fundic gland zone of adult pigs, potentially due to a shift of H. suis colonization from the pyloric to the fundic gland zone...

BACKGROUND: The pH of the human gastric mucosa varies around 2.5 so that only bacteria with strong acidic stress tolerance can colonize it. The ulcer causing Helicobacter pylori thrives in the gastric mucosa. We analyse the roles of the key outer membrane protein OMPLA in its roles in acid tolerance. RESULTS: The homology model of Helicobacter pylori outer membrane phospholipase A (OMPLA) reveals a twelve stranded β-barrel with a pore that allows molecules to pass with a diameter up to 4 Å...

The sphincters failure is a part of NSAIDs-toxicity that can be accordingly counteracted. We used a safe stable gastric pentadecapeptide BPC 157 (GEPPPGKPADDAGLV, MW 1419), LD1 not achieved, since successful in inflammatory bowel disease trials, and counteracts esophagitis, sphincters failure, gastrointestinal ulcer and skin ulcer, external and internal fistulas in rats, and particularly counteracts all NSAIDs-lesions. We assessed lower esophageal sphincter and pyloric sphincter pressure (cmH2O) in rats treated with various NSAIDs regimens, at corresponding time points, known to produce stomach, small intestine lesions, hepatotoxicity and encephalopathy...
