Prognostic significance of the degree of lymphatic vessel invasion in locally advanced, surgically resectable pancreatic head cancer: A single center experience.

Medicine (Baltimore) 2018 Dec;97(49):e13466

Department of Diagnostic Pathology, Jichi Medical University Hospital.

Little is known concerning the prognostic significance of the degree of lymphatic vessel invasion in pancreatic head cancer. To address this gap in knowledge, we retrospectively examined 60 patients with locally advanced, surgically resectable pancreatic head cancer who underwent pancreaticoduodenectomy and lymph node (LN) dissection.All cases were histopathologically diagnosed as ductal adenocarcinoma, stage II (25 pT3N0 cases, 35 pT3N1 cases).

Eimeria challenge adversely affected long bone attributes linked to increased resorption in 14-day-old broiler chickens.

Poult Sci 2018 Dec 13. Epub 2018 Dec 13.

Department of Animal Biosciences, University of Guelph, Guelph, ON N1G 2W1, Canada.

There is limited information on the effects of enteric pathogen on bone quality in rapidly growing broiler chicks. We examined tibia and femur attributes (length, diameter, relative weight of ash content [AC] to the BW, ash concentration [AP]) and serum bone-turnover markers including receptor activator of nuclear factor kappa-B ligand (RANKL) for resorption, alkaline phosphatase (ALP) for mineralization, and selected serum metabolites in 14-day-old broilers challenged with Eimeria. A total of 160 (80 males and 80 females) 1-day-old Ross × Ross 708 chicks were used. Read More

Porcine Intestinal Enteroids: a New Model for Studying Enteric Coronavirus PEDV Infection and the Host Innate Response.

J Virol 2018 Dec 12. Epub 2018 Dec 12.

State Key Laboratory of Veterinary Biotechnology, Harbin Veterinary Research Institute, Chinese Academy of Agricultural Sciences

Porcine epidemic diarrhea virus (PEDV), a member of the group of alphacoronaviruses, is the pathogen of a highly contagious gastrointestinal swine disease. The elucidation of the events associated with the intestinal epithelial response to PEDV infection has been limited by the absence of good porcine intestinal models that recapitulate the multicellular complexity of the gastrointestinal tract. Here, we generated swine enteroids from the intestinal crypt stem cells of the duodenum, jejunum, or ileum, and found that the generated enteroids are able to satisfactorily recapitulate the complicated intestinal epithelium and are susceptible to infection by PEDV.

Effects of Chemical Speciation on the Bioaccessibility of Zinc in Spiked and Smelter-Affected Soils.

Environ Toxicol Chem 2018 Dec 7. Epub 2018 Dec 7.

Department of Soil Science, University of Saskatchewan, Saskatoon, SK, S7N 5A8, Canada.

Previous studies have suggested that understanding soil metal speciation, rather than relying solely on total metal content, can improve the accuracy and utility of contaminated site risk assessments. Since soil properties and reaction time can alter metal speciation, then speciation should influence metal bioaccessibility. For example, under gastrointestinal conditions, it is expected that metal species will differ in bioaccessibility depending upon their stability in acidic pH environments. Read More

Laparoscopic repair of a perforated duodenal ulcer: another use of a round ligament flap.

Wideochir Inne Tech Maloinwazyjne 2018 Dec 30;13(4):542-545. Epub 2018 May 30.

Department of Digestive Surgery, Amiens University Hospital, Amiens, France.

Management of a perforated duodenal ulcer is most commonly performed by laparoscopy and consists of suture of the perforation after performing lavage of the peritoneal cavity. In most cases, a flap is created, and an omental flap is usually the preferred choice because of its simplicity and its proximity to the site of duodenal perforation. However, in some cases, the greater omentum cannot be used due to the severity of peritonitis or due to previous surgical removal. Read More

Cobalamin is a member of the B-group of vitamins and a cofactor for metabolic processes like nucleic acid synthesis, amino acid synthesis, and the citric acid cycle. Mammals are unable to synthesize cobalamin and therefore rely on adequate food intake. Cobalamin absorption is a complex process in the stomach, duodenum, and ileum, requiring a functional exocrine pancreas. Read More

Divisions of Endocrinology and Diabetology, Division of Gastroenterology and Hepatology, Medizinische Universitat Graz, Graz, Austria.

Introduction: A 60-cm endoscopically implantable duodenal-jejunal bypass liner (Endobarrier™, GI Dynamics, Lexington, MA, USA) has been introduced as a therapeutic option to support weight loss for a selected group of obese subjects with type 2 diabetes mellitus (T2DM). The sleeve prevents contact between chyme and the intestinal mucosa of the upper gastrointestinal tract. The primary aim of this study is to elucidate the changes in insulin sensitivity and beta-cell function after EndoBarrier™ implantation in obese patients with T2DM; changes in gut permeability and gut microbiome are also to be examined.

At the crossroads of oxygen and iron sensing: hepcidin control of HIF-2α.

Authors:
Frank S Lee

J Clin Invest 2018 Dec 10. Epub 2018 Dec 10.

Hepcidin is the master regulator of iron metabolism. It plays a key role in the regulation of iron transport across the duodenal epithelium, which in turn is dependent on the oxygen-regulated transcription factor hypoxia-inducible factor 2α (HIF-2α). In this issue of the JCI, Schwartz and colleagues show that duodenal HIF-2α is itself regulated by hepcidin, thereby indicating that this transcription factor is not only regulated by oxygen, but also by iron.

The pancreatic and duodenal homeobox 1 (Pdx1) is an essential pancreatic transcription factor. The C-terminal intrinsically disordered domain of Pdx1 (Pdx1-C) has a heavily biased amino acid composition; most notably, 18 of 83 residues are proline, including a hexa-proline cluster near the middle of the chain. For these reasons, Pdx1-C is an attractive target for structure characterization, given the availability of suitable methods. Read More

Universität Hohenheim, Stuttgart, Germany.

Clinical interventions in the stomach have been linked to fecal microbiota alterations, suggesting a function of the stomach in gastrointestinal (GI) homeostasis. We sought to determine the taxonomic bacterial biogeography of the upper GI tract, including different sites within the human stomach (cardia, corpus, and antrum), adjacent upstream (esophagus) and downstream (duodenum) locations, and luminal contents (aspirate), as well as whole-stomach samples from mice and gerbils. Qualitative and quantitative DNA- and RNA-based taxonomic microbiota analyses were combined to study the relationship of relative and absolute bacterial abundances and transcriptionally active bacterial microbiota components in the stomach of humans and mice.
