Hepatobiliopancreatic surgery is challenging becouse of the complexity of resections and reconstructions and variability of vascular anatomy. The arterial vascularization of the liver is susteined by the common hepatic artery (CHA) that originates from the celiac trunk (CT). The CHA bifurcates into the gastroduodenal artery (GDA) and proper hepatic artery (PHA) 0.5-1 cm medial to the common bile duct (CBD), and the PHA bifurcates into a right and a left branch at hepatic hilum. The most frequent variants are the right hepatic artery (RHA) from the superior mesenteric artery (SMA), the left hepatic artery (LHA) from the left gastric artery (LGA) or a combination of these two variants...

INTRODUCTION: `The growth hormone secretagogue receptor 1a (GHS-R1a) is the orphan G-protein-coupled receptor, and its endogenous ligand is ghrelin. GHS-R1a contributes to regulation of glucose homeostasis, memory and learning, food addiction, and neuroprotection. Several PET tracers for GHS-R1a have been developed, but none have been reported to be clinically applicable to GHS-R1a imaging. In this study, we developed three new PET tracers for GHS-R1a: (18)F-labeled 6-(4-chlorophenyl)-3-((1-(2-fluoroethyl)piperidin-3-yl)methyl)-2-(o-tolyl)quinazolin-4(3H)-one (1), (11)C-labeled 6-(4-chlorophenyl)-3-((1-(2-methoxyethyl)piperidin-3-yl)methyl)-2-(o-tolyl)quinazolin-4(3H)-one (2), and (11)C-labeled (S)-(4-(1H-indole-6-carbonyl)-3-methylpiperazin-1-yl)(4'-methoxy-[1,1'-biphenyl]-4-yl)methanone (3)...

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...

Destruction of the insulin-producing β-cells is the key determinant of diabetes mellitus regardless of their types. Due to their anatomical location within the islets of Langerhans scattered throughout the pancreas, it is difficult to monitor β-cell function and mass clinically. To this end, we propose to use a mathematical model of glucose-insulin homeostasis to estimate insulin secretion, glucose uptake by tissues, and hepatic handling of glucose. We applied the mathematical model by Lombarte et al. (2013) to compare various rate constants representing glucose-insulin homeostasis between lean (11% fat)- and high fat diet (HFD; 45% fat)-fed mice...

Oxidized tyrosine products are commonly found in food with high protein content and have been demonstrated to cause damage of liver and kidney in our previous studies. Dityrosine (Dityr) is a typical oxidized tyrosine product. Due to its structural homology with thyroid hormones T3, we assumed that one of the endocrine systems most likely considered in connection with its disruption by Dityr may be the T3 action. T3 plays important roles in insulin synthesis, and thyroid hormone resistance (RTH) is associated with the impairment of glucose metabolism...

BACKGROUND: Organ dysfunction is common after neurologic determination of death (NDD) but before organ collection. Reliable markers for graft success following transplant of these organs would be useful. We sought to determine the relationship between the donor after neurologic determination of death (DNDD) pathophysiology and successful organ donation. METHODS: Donor information was obtained through the local organ procurement organization. Donor demographics and clinical data points for cardiovascular, renal, respiratory, hepatic, hematological and neuroendocrine systems were reviewed 12 h before and 12 h after neurologic determination of death was declared...

Short beak and dwarfism syndrome virus (SBDSV) is a newly emerging distinct duck-origin goose parvovirus that belongs to the genus Dependovirus. Our previous studies have found that SBDSV was highly pathogenic to Cherry Valley ducklings and mule ducklings. However, little is known about its pathogenicity to other waterfowls. In the present study, the pathogenicity of SBDSV was evaluated in domesticated waterfowl including Muscovy ducklings, Sheldrake ducklings and domestic goslings. All experimentally infected birds exhibited remarkable growth retardation, anorexia and diarrhea similar to naturally infected birds...

BACKGROUND: Owing to limited availability of donor organs, previous solid organ transplant (SOT) recipients are increasingly considered as potential organ donors. We report donor-derived transmission of herpes simplex virus type-2 (HSV-2) to two clusters of SOT recipients with transmission from the original donor and an HSV-2-infected recipient who subsequently became a donor. METHODS: We reviewed medical records of the donors and recipients in both clusters. Pre-transplant serology and virological features of HSV-2 were characterized...

BACKGROUND AND AIMS: Neuroendocrine tumors (NETs) are a heterogeneous group of neoplasms with unclear etiology that may show functioning or non-functioning features. Primary tumor localization often requires integrated imaging. The European Neuroendocrine Tumors Society (ENETS) guidelines proposed wireless-capsule endoscopy (WCE) as a possible diagnostic tool for NETs, if intestinal origin is suspected. However, its impact on therapeutic management is debated. We aimed to evaluate the yield of WCE in detecting intestinal primary tumors in patients showing liver NET metastases when first-line investigations are inconclusive...

Antibiotic prophylaxis in the perioperative period is the standard of care for nearly all surgical procedures and routinely prescribed during solid organ transplantation (SOT). The primary goal of perioperative antibiotic prophylaxis is to minimize postoperative surgical site infections (SSIs). SSIs are a significant issue in SOT. Depending on the organ transplanted, SSIs occur in 3 to 53% of patients, with the highest rates observed in small bowel/multivisceral, liver, and pancreas transplant recipients. SOT recipients are also at increased risk of developing SSIs with antimicrobial-resistant organisms...

REVIEW
S Gulati, A Misra
Obesity and type 2 diabetes are increasing in rural and urban regions of South Asia including India. Pattern of fat deposition in abdomen, ectopic fat deposition (liver, pancreas) and also low lean mass are contributory to early-onset insulin resistance, dysmetabolic state and diabetes in Asian Indians. These metabolic perturbations are further exacerbated by changing lifestyle, diet urbanization, and mechanization. Important dietary imbalances include increasing use of oils containing high amount of trans fatty acids and saturated fats (partially hydrogenated vegetable oil, palmolein oil) use of deep frying method and reheating of oils for cooking, high intake of saturated fats, sugar and refined carbohydrates, low intake of protein, fiber and increasing intake of processed foods...

BACKGROUND/AIMS: Somatostatin receptor (SSTR) scintigraphy (SRS) is the standard imaging modality for evaluation of gastroenteropancreatic neuroendocrine tumor (GEP-NET) in Western countries. However, this modality was not approved in Japan until recently. The purpose of this study was to evaluate the clinical efficacy of SRS for detecting GEP-NET in Japanese patients. METHODS: Japanese patients with advanced GEP-NET were enrolled and evaluated by the SRS and CT...
