“…As a result, the intrapancreatic bile duct runs between the dorsal and ventral pancreas, neither inside the dorsal pancreas nor the ventral pancreas. This configuration is confirmed in human fetal pancreas as well [ 9 ]. Also, the intrapancreatic bile duct is covered by the pancreatic lingula [ 8 ], which derives from the ventral pancreas.…”

A case of double common bile duct in a deceased donor for transplantation

A double common bile duct is extremely rare among the anatomical variations in the biliary tract system. We report an incidentally encountered case of the double common bile duct and discuss the novel anatomical findings of the accessory common bile duct from the viewpoint of embryology. A unique point of our case is that the accessory common bile duct bifurcated at the level of the intrapancreatic bile duct. There is no similar case in the previous literature among type II double common bile duct in the viewpoint of anatomical findings of the accessory common bile duct. We assume that this asymptomatic anatomical variation may be present more commonly, but not diagnosed.

“…Due to the thick portal vein, we originally regarded the portal vein bifurcation as the most superiorly located structure in the hilar vessels and ducts. Indeed, we previously showed that the fetal topographical anatomy near and on the pancreatic head differ considerably from that in adults (Jin et al,2010; Yu et al,2011). In particular, we found that the portal vein and the hepatic artery arising from the superior mesenteric artery were on the superior side of the pancreatic head.…”

“…Thus, these specimens may have contained anomalies at or close to the GB. However, using our previous experience (Hwang et al,2010; Jin et al,2010; Yu et al,2011) and critical views of hepatic duct variation (Fig. 1; see the Introduction), we carefully determined whether any morphology was common to the specimens.…”

Fetal intrahepatic gallbladder and topographical anatomy of the liver hilar region and hepatocystic triangle

The fetal gallbladder (GB) is embedded in a deep fossa surrounded by the liver parenchyma. Using 15 specimens with intrahepatic GB (crown-rump length 45-92 mm; approximately 9-13 weeks of gestation), we assessed the fetal topographical anatomy of the hepatocystic triangle and the porta hepatis. The cystic duct displayed a long upward course (0.9-4.5 mm along the supero-inferior axis) from the GB, along the duodenum, to the common bile duct in the hepatoduodenal ligament, via an independent mesentery separated from liver parenchyma by a recess of the peritoneal cavity. Notably, the course varied in length among specimens, not among stages. At the porta hepatis, we were able to distinguish the supraportal course of the posterior right hepatic duct overriding a portal vein branch to segment 8 (6/15) from the other, infraportal course (9/15). In the latter type, the portal vein bifurcation was superior to the cystic duct course. Two margins of the hepatocyctic triangle were very long in fetuses because of the inferiorly located intrahepatic GB. Thus, the triangle seems to be difficult to identify in prenatal ultrasound. During changes in location after 9 weeks, the GB fundus remains attached to the liver because the cystic artery was often embedded in the liver parenchyma. A failure in the embedding and re-exposure process of the GB may result in anomalous peritoneal folds around the GB.

“…Fungi are well-known producers of bioactive secondary metabolites, especially short peptides of 30 residues or fewer, with interesting structures and antibiotic properties (Brase et al 2009;Jia et al 2015;Li et al 2017;Wang et al 2017a, b;Yu et al 2012). Herein, we focus on fungal cyclodipeptides known as 2,5-diketopiperazines (DKPs), as well as typical peptides and their analogs, reported since 2000.…”

The 2,5-diketopiperazines (DKPs) are the smallest cyclopeptides and their basic structure includes a six-membered piperazine nucleus. Typical peptides lack a special functional group in the oligopeptide nucleus. Both are produced by at least 35 representative genera of fungi, and possess huge potential as pharmaceutical drugs and biocontrol agents. To date, only cyclosporin A has been developed into a commercial product. This review summarises 186 fungi-derived compounds reported since 2000. Antibiotic (antibacterial, antifungal, synergistic antifungal, antiviral, antimycobacterial, antimalarial, antileishmanial, insecticidal, antitrypanosomal, nematicidal and antimicroalgal) activities are discussed for 107 of them, including 66 DKPs (14 epipolythiodioxopiperazines, 20 polysulphide bridgefree thiodiketopiperazines, and 32 sulphur-free prenylated indole DKPs), 15 highly N-methylated, and 26 non-highly N-methylated typical peptides. Structureactivity relationships, mechanisms of action, and research methods are covered in detail. Additionally, biosynthases of tardioxopiperazines and neoechinulins are highlighted. These compounds have attracted considerable interest within the pharmaceutical and agrochemical industries.
