Hemorrhagic enteritis (HE) is an acute viral disease that affects avian species, particularly turkeys, compromising their commercial production and having a negative effect on animal welfare. Turkey adenovirus 3 (TAdV-3), is the main causal agent of the disease. In this study, we considered 3 groups of turkeys to achieve 2 purposes: 1) A preliminary investigation on the microbiota content in the 4 parts of healthy turkey's intestine (group A), namely duodenum, jejunum, ileum, and ceca was done; 2) an investigation on the relationship between natural infections with TAdV-3 and the intestinal microbiota in the jejunum, where HE mostly develops, comparing group A with animals with molecular positivity for the virus and with clinical signs of HE (group B) and animals with molecular positivity for the virus but without clinical signs (group C)...

Two experiments were conducted to determine the effect of an encapsulated sodium butyrate (Na-B) with targeted releasing times on broiler performance, energy digestibility, intestinal morphology, and ceca Salmonella colonization. In experiment 1, 3 different Na-B products (CMA, CMP, and CMS) were evaluated following a challenge with a nalidixic acid-resistant Salmonella typhimurium (STNAR). Cobb-Cobb male birds were placed 8 per pen into 6 replicates for each treatment. Treatments included 6 Na-B treatments (500 and 1,000 ppm of each product) plus 2 control (non-challenged and challenged)...

Although the intestine plays the major role in 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) action on calcium homeostasis, the mechanisms involved remain incompletely understood. The established model of 1,25(OH)2D3 regulated intestinal calcium absorption postulates a critical role for the duodenum. However it is the distal intestine where 70 -80% of the ingested calcium is absorbed. In order to test directly the role of 1,25(OH)2D3 and the vitamin D receptor (VDR) in the distal intestine, 3 independent knockout (KO) /transgenic (TG) lines expressing VDR exclusively in the ileum, cecum and colon were generated by breeding VDR KO mice with TG mice expressing human (h)VDR under the control of the 9...

PURPOSE: In vivo drug dissolution in the gastrointestinal (GI) tract is largely unmeasured. The purpose of this clinical study was to evaluate the in vivo drug dissolution and systemic absorption of the BCS Class IIa drug ibuprofen under fed and fasted conditions by direct sampling of stomach and small intestinal luminal content. Expanding current knowledge of drug dissolution in vivo will help to establish physiologically relevant in vitro models predictive of drug dissolution. METHODS: A multi-lumen GI catheter was orally inserted into the GI tract of healthy human subjects...

Background and study aims Linear endoscopic ultrasound (EUS) evaluation of the pancreaticobiliary system usually requires scanning from both the stomach and the duodenum. The feasibility of assessing the complete pancreaticobiliary system from the stomach alone has not been studied. We aimed to conceptualize a system-based approach (the railroad approach) for linear pancreaticobiliary EUS (PB-EUS) and evaluate whether the pancreaticobiliary anatomy could be assessed from the stomach alone. Patients and methods Three maneuvers were conceptualized and evaluated (the alpha maneuver in the stomach, and sigma and xi maneuvers in the duodenum)...

BACKGROUND: Pediatric intra-abdominal injuries (IAI) from blunt abdominal trauma (BAT) rarely require emergent intervention. For those children undergoing procedural intervention, our aim was to understand the timing and indications for operation and angiographic embolization. METHODS: We prospectively enrolled children younger than 16 years after BAT at 14 Level I Pediatric Trauma Centers over a 1-year period. Patients with IAI who received an intervention (IAI-I) were compared with those who did not receive an intervention using descriptive statistics and univariate analysis; p less than 0...

Acute acidosis that results from short-term exercise delays gastric emptying in rats and decreases the responsiveness to carbachol in gastric fundus strips. The regulation of cytosolic Ca(2+) levels appears to be a mechanism of action of acidosis. The present study investigated the way in which acidosis interferes with gastric smooth muscle contractions. Rat gastric fundus isolated strips at pH 6.0 presented a lower magnitude of carbachol-induced contractions compared with preparations at pH 7.4. This lower magnitude was absent in carbachol-stimulated duodenum and KCl-stimulated gastric fundus strips...

BACKGROUND: Medullary thyroid carcinoma (MTC) is a rare disease. Treatment options for recurrent disease are limited. Somatostatin analogues might have a role as anticancer agents agents in MTC, although the evidence is inconclusive. PATIENT FINDINGS: A 64-year old male was diagnosed with MTC in January 2010. Total thyroidectomy with neck dissection (stage IVA, pT2pN1bM0, R1) was performed, followed by adjuvant locoregional radiotherapy. Two years later, the patient developed recurrent metastatic disease evidenced by elevated carcinoembryonic antigen (CEA) and calcitonin levels, and a positive uptake (Octreoscan®) in the right adrenal gland and pancreatic head...

Impaired intestinal barrier function promotes the progression of various liver diseases including cholestatic liver disease. The close association of primary sclerosing cholangitis (PSC) with inflammatory bowel disease highlights the importance of the gut-liver axis. It has been reported that bile duct ligation (BDL)-induced liver fibrosis is significantly reduced in C/EBP homologous protein knock out (CHOP(-/-) ) mice. However, the underlying mechanisms remain unclear. In the current study, we demonstrate that BDL induces striking and acute hepatic ER stress responses after 1 day, which return to normal after 3 days...

Systemic iron homeostasis is maintained by regulation of iron absorption in the duodenum, iron recycling from erythrocytes, and iron mobilization from the liver and is controlled by the hepatic hormone hepcidin. Hepcidin expression is induced via the bone morphogenetic protein (BMP) signaling pathway that preferentially uses two type-I (ALK2 and ALK3) and two type-II (ActRIIA and Bmpr2) BMP receptors. Hemojuvelin (HJV), HFE, and transferrin receptor-2 (TfR2) facilitate this process presumably by forming a plasma membrane complex with BMP receptors...

BACKGROUND: In the current era, trainees frequently use unvetted online resources for their own education, including viewing surgical videos on YouTube. While operative videos are an important resource in surgical education, YouTube content is not selected or organized by quality but instead is ranked by popularity and other factors. This creates a potential for videos that feature poor technique or critical safety violations to become the most viewed for a given procedure. METHODS: A YouTube search for "Laparoscopic cholecystectomy" was performed...

BACKGROUND: Biliary complications continue to be the 'Achilles heel' of living donor liver transplantation (LDLT). The use of biliary stents in LDLT to reduce biliary complication is a controversial issue. We performed a randomized trial to study the impact of intraductal biliary stents on postoperative biliary complications following LDLT. STUDY DESIGN: Of the 94 LDLT's, that were performed during a period of 16 months, ABO incompatible transplants, left lobe grafts, ≥3 ducts on the graft and those requiring bilio-enteric drainage were excluded...
