Abstract

Abstract Background Locally advanced pancreatic ductal adenocarcinoma (PDAC), accounting for about 30% of PDAC patients, is difficult to cure by radical resection or systemic chemotherapy alone. A multidisciplinary strategy is required and our TT-LAP trial aims to evaluate whether triple-modal treatment with proton beam therapy (PBT), hyperthermia, and gemcitabine plus nab-paclitaxel is a safe and synergistically effective treatment for patients with locally advanced PDAC. Methods This trial is an interventional, open-label, non-randomized, single-center, single-arm phase I/II clinical trial organized and sponsored by the University of Tsukuba. Eligible patients who are diagnosed with locally advanced pancreatic cancer, including both borderline resectable (BR) and unresectable locally advanced (UR-LA) patients, and selected according to the inclusion and exclusion criteria will receive triple-modal treatment consisting of chemotherapy, hyperthermia, and proton beam radiation. Treatment induction will include 2 cycles of chemotherapy (gemcitabine plus nab-paclitaxel), proton beam therapy, and 6 total sessions of hyperthermia therapy. The initial 5 patients will move to phase II after adverse events are verified by a monitoring committee and safety is ensured. The primary endpoint is 2-year survival rate while secondary endpoints include adverse event rate, treatment completion rate, response rate, progression-free survival, overall survival, resection rate, pathologic response rate, and R0 (no pathologic cancer remnants) rate. The target sample size is set at 30 cases. Discussion The TT-LAP trial is the first to evaluate the safety and effectiveness (phases1/2) of triple-modal treatment comprised of proton beam therapy, hyperthermia, and gemcitabine/nab-paclitaxel for locally advanced pancreatic cancer. Ethics and dissemination This protocol was approved by the Tsukuba University Clinical Research Review Board (reference number TCRB22-007). Results will be analyzed after study recruitment and follow-up are completed. Results will be presented at international meetings of interest in pancreatic cancer plus gastrointestinal, hepatobiliary, and pancreatic surgeries and published in peer-reviewed journals.

Abstract

Abstract Ectopic varices due to extrahepatic portal vein obstruction (EHO) after hepaticojejunostomy have been previously reported. However, few case reports have described angiodysplasia‐like lesions due to EHO around the hepaticojejunal anastomosis because they comprise small vessels in the mucosal surface and cannot be detected by contrast‐enhanced computed tomography. Physicians need to insert the endoscope into the long afferent limb to diagnose angiodysplasia‐like lesions around the hepaticojejunal anastomosis. Some reports have described that endoscopy stops bleeding from angiodysplasia‐like lesions around the hepaticojejunal anastomosis; however, a standard methodology remains to be established. We present three cases of bleeding from an angiodysplasia‐like lesion around the hepaticojejunal anastomosis that were successfully treated using argon plasma coagulation (APC) with balloon‐assisted enteroscopy. Although one patient died owing to cancer progression 3 months after APC hemostasis, the hemostatic effect persisted for >2 years in the remaining two patients. These results suggest that APC is a good treatment option to stop bleeding from angiodysplasia‐like lesions at hepaticojejunal anastomosis.

Abstract

Whole-genome duplication and genome compaction are thought to have played important roles in teleost fish evolution. Ayu (or sweetfish), Plecoglossus altivelis, belongs to the superorder Stomiati, order Osmeriformes. Stomiati is phylogenetically classified as sister taxa of Neoteleostei. Thus, ayu holds an important position in the fish tree of life. Although ayu is economically important for the food industry and recreational fishing in Japan, few genomic resources are available for this species. To address this problem, we produced a draft genome sequence of ayu by whole-genome shotgun sequencing and constructed linkage maps using a genotyping-by-sequencing approach. Syntenic analyses of ayu and other teleost fish provided information about chromosomal rearrangements during the divergence of Stomiati, Protacanthopterygii and Neoteleostei. The size of the ayu genome indicates that genome compaction occurred after the divergence of the family Osmeridae. Ayu has an XX/XY sex-determination system for which we identified sex-associated loci by a genome-wide association study by genotyping-by-sequencing and whole-genome resequencing using wild populations. Genome-wide association mapping using wild ayu populations revealed three sex-linked scaffolds (total, 2.03 Mb). Comparison of whole-genome resequencing mapping coverage between males and females identified male-specific regions in sex-linked scaffolds. A duplicate copy of the anti-Müllerian hormone type-II receptor gene (amhr2bY) was found within these male-specific regions, distinct from the autosomal copy of amhr2. Expression of the Y-linked amhr2 gene was male-specific in sox9b-positive somatic cells surrounding germ cells in undifferentiated gonads, whereas autosomal amhr2 transcripts were detected in somatic cells in sexually undifferentiated gonads of both genetic males and females. Loss-of-function mutation for amhr2bY induced male to female sex reversal. Taken together with the known role of Amh and Amhr2 in sex differentiation, these results indicate that the paralog of amhr2 on the ayu Y chromosome determines genetic sex, and the male-specific amh-amhr2 pathway is critical for testicular differentiation in ayu.

Abstract

Abstract The effects of α-melanocyte-stimulating hormone (α-MSH) on calcium metabolism were examined with goldfish. The scales on the left side of goldfish bodies were removed to allow the regeneration of scales under anesthesia. Thereafter, the influences of α-MSH injection (low dose: 0.1 μg/g body weight; high dose: 1 μg/g body weight) on plasma calcitonin (calcium-regulating hormone) and the calcium content of the scales were investigated. Ten days after removing the scales, we measured the plasma calcitonin and calcium content of both regenerating scales on the left side and ontogenic scales on the right side. At both doses of α-MSH injection, plasma calcitonin concentrations in the α-MSH-treated group were significantly higher than those in the control group. The mRNA expressions of α-MSH-receptors were detected in the ultimobranchial glands (secretory organ of calcitonin), indicating that α-MSH directly functions in ultimobranchial glands and promotes calcitonin secretion. Furthermore, we found that the calcium content of regenerating scales in α-MSH-treated goldfish was higher than that in control goldfish, while the calcium content of ontogenic scales on the right side was significantly decreased by α-MSH injection. There was a significant co-relationship between plasma calcitonin and the calcium content of regenerating scales. The mRNA expression of calcitonin receptors in regenerating scales was remarkably higher than that in ontogenic scales. These results imply that calcitonin functions to promote scale regeneration resulting from the inhibition of bone resorption because calcitonin suppresses osteoclastic activity. Thus, we are the first to demonstrate the interaction between α-MSH and calcitonin in teleosts.

Abstract

The effects of mixing vanes (MVs) attached to a grid spacer on the characteristics of air–water annular flows were experimentally investigated. To know the effects, a grid spacer with or without MV was inserted in a vertical circular pipe of 16-mm internal diameter. For three cases (i.e., no spacer, spacer without MV, and spacer with MV), the liquid film thickness, liquid entrainment fraction, and deposition rate were measured by the constant current method, single liquid film extraction method, and double liquid film extraction method, respectively. The MVs significantly promote the re-deposition of liquid droplets in the gas core flow into the liquid film on the channel walls. The deposition mass transfer coefficient is three times higher for the spacer with MV than for the spacer without MV, even for cases 0.3-m downstream from the spacer. The liquid film thickness becomes thicker upstream and downstream for the spacer with MV, compared with the thickness for the spacer without MV and for the case with no spacer.

Abstract

Arterioportal fistula (APF) combined with a visceral artery pseudoaneurysm is an exceptionally rare and critical vascular disorder of the abdominal viscera, with pseudoaneurysm rupture being potentially fatal and severe APF leading to portal hypertension, both of which necessitate immediate intervention. An 87-year-old woman with a history of pancreatitis presented with upper abdomen and back pain. Laboratory tests revealed elevated amylase levels and severe anemia. A computed tomography (CT) scan showed a large dorsal pancreatic artery (DPA) pseudoaneurysm with a fistula to the main portal vein. Given her advanced age, surgery was deemed high-risk, and endovascular treatment was selected. Transcatheter arterial embolization was successfully performed using coils to embolize the DPA pseudoaneurysm. A follow-up CT 1 week postprocedure confirmed the absence of a pseudoaneurysm and no further progression of anemia.

Abstract

The nucleotide sequence of a sardine preprocalcitonin precursor has been determined from their ultimobranchial glands in the present study. From our analysis of this sequence, we found that sardine procalcitonin was composed of procalcitonin amino-terminal cleavage peptide (N-proCT) (53 amino acids), CT (32 amino acids), and procalcitonin carboxyl-terminal cleavage peptide (C-proCT) (18 amino acids). As compared with C-proCT, N-proCT has been highly conserved among teleosts, reptiles, and birds, which suggests that N-proCT has some bioactivities. Therefore, both sardine N-proCT and sardine CT were synthesized, and their bioactivities for osteoblasts and osteoclasts were examined using our assay system with goldfish scales that consisted of osteoblasts and osteoclasts. As a result, sardine N-proCT (10− 7 M) activated osteoblastic marker enzyme activity, while sardine CT did not change. On the other hand, sardine CT (10− 9 to 10− 7 M) suppressed osteoclastic marker enzyme activity, although sardine N-proCT did not influence enzyme activity. Furthermore, the mRNA expressions of osteoblastic markers such as type 1 collagen and osteocalcin were also promoted by sardine N-proCT (10− 7 M) treatment; however, sardine CT did not influence their expressions. The osteoblastic effects of N-proCT lack agreement. In the present study, we can evaluate exactly the action for osteoblasts because our scale assay system is very sensitive and it is a co-culture system for osteoblasts and osteoclasts with calcified bone matrix. Both CT and N-proCT seem to influence osteoblasts and osteoclasts and promote bone formation by different actions in teleosts. © 2017 Elsevier Inc., Embargo Period 12 months

Abstract

Exposure to microgravity during space flight has caused astronauts to experience decreased bone density, resulting from bone resorption by osteoclastic activation. Activation of the nuclear factor-κB ligand (RANKL) of the RANKLproducing cells, a known osteoclastogenesispromoting factor, seems to be induced under microgravity. However, the role of the RANKLproducing cells under microgravity has not yet been demonstrated due to the lack of suitable in vitro organ culture of osteoblasts, osteoclasts, and osteocytes with the intact bone matrix under microgravity. Previous reports demonstrated that RANKL-producing cells were detected with a specific antiserum for goldfish RANKL in the regenerating goldfish scales. In this study, the response of RANKLproducing cells to simulated microgravity with a three-dimensional clinostat was examined using in vitro organ culture system with regenerating scales. In addition, mRNA expression analysis of osteoclastic and osteoblastic markers via quantitative real-time PCR was conducted together with histological analysis of RANKL-producing cells. After 4 days of exposure to simulated microgravity, the number of RANKL immune-positive cells increased compared with the RANKL immunepositive cells in control regenerating scales. The Rankl mRNA expression in the regenerating scales after simulated microgravity treatments was significantly higher than that in the control (1G) scales. The mRNA expression of osteoprotegerin (Opg), an osteoclastogenesis inhibitory factor, significantly decreased under simulated microgravity conditions. The ratio of Rankl/Opg in the simulated microgravity-treated scales was significantly higher than that in the scales of 1G control. The change in the ratio of Rankl/Opg implied that osteoclastic activation is promoted after simulated microgravity treatments. Actually, in the regenerating scales exposed to simulated microgravity, the mRNA expression of osteoclastic markers, such as receptor activator of NFκB, cathepsin K, integrin beta-3, and cellular-Src, significantly increased. On the other hand, the mRNA expression of the osteoblastic markers (collagen type I alpha 1 and osteocalcin) significantly decreased. The changes in the osteoclastic and osteoblastic markers were consistent with our previously reported experiment on the International Space Station. To the best of our knowledge, we are the first to demonstrate the activation of RANKL-producing cells under simulated microgravity conditions by in vitro organ culture using regenerating goldfish scales. We strongly emphasize that fish scales serve as an excellent bone model for the analysis of gravitational responses while maintaining conditions similar to in vivo. [ABSTRACT FROM AUTHOR]

Abstract

We have developed an original in vitro bioassay using teleost scale, that has osteoclasts, osteoblasts, and bone matrix as each marker: alkaline phosphatase (ALP) for osteoblasts and tartrate-resistant acid phosphatase (TRAP) for osteoclasts. Using this scale in vitro bioassay, we examined the effects of seawater polluted with highly concentrated polycyclic aromatic hydrocarbons (PAHs) and nitro-polycyclic aromatic hydrocarbons (NPAHs) on osteoblastic and osteoclastic activities in the present study. Polluted seawater was collected from two sites (the Alexandria site on the Mediterranean Sea and the Suez Canal site on the Red Sea). Total levels of PAHs in the seawater from the Alexandria and Suez Canal sites were 1364.59 and 992.56 ng/l, respectively. We were able to detect NPAHs in both seawater samples. Total levels of NPAHs were detected in the seawater of the Alexandria site (12.749 ng/l) and the Suez Canal site (3.914 ng/l). Each sample of polluted seawater was added to culture medium at dilution rates of 50, 100, and 500, and incubated with the goldfish scales for 6 hrs. Thereafter, ALP and TRAP activities were measured. ALP activity was significantly suppressed by both polluted seawater samples diluted at least 500 times, but TRAP activity did not change. In addition, mRNA expressions of osteoblastic markers (ALP, osteocalcin, and the receptor activator of the NF-κB ligand) decreased significantly, as did the ALP enzyme activity. In fact, ALP activity decreased on treatment with PAHs and NPAHs. We conclude that seawater polluted with highly concentrated PAHs and NPAHs influences bone metabolism in teleosts. © 2016 Zoological Society of Japan., Embargo Period 12 months

Abstract

To analyze the effect of polychlorinated biphenyl (PCB) 118 on fish bone metabolism, we examined osteoclastic and osteoblastic activities, as well as plasma calcium levels, in the scales of PCB (118)-injected goldfish. In addition, effect of PCB (118) on osteoclasts and osteoblasts was investigated in vitro. Immature goldfish, in which the endogenous effects of sex steroids are negligible, were used. PCB (118) was solubilized in dimethyl sulfoxide at a concentration of 10 ppm. At 1 and 2 days after PCB (118) injection (100 ng/g body weight), both osteoclastic and osteoblastic activities, and plasma calcium levels were measured. In an in vitro study, then, both osteoclastic and osteoblastic activities as well as each marker mRNA expression were examined. At 2 days, scale osteoclastic activity in PCB (118)-injected goldfish increased significantly, while osteoblastic activity did not change significantly. Corresponding to osteoclastic activity, plasma calcium levels increased significantly at 2 days after PCB (118) administration. Osteoclastic activation also occurred in the marker enzyme activities and mRNA expressions in vitro. Thus, we conclude that PCB (118) disrupts bone metabolism in goldfish both in vivo and in vitro experiments. © 2012 The Author(s).

Abstract

Hepatolithiasis is well known to be a late complication after biliary reconstruction. However, there were few reports regarding hepatolithiasis in late complications of long-term, native liver survivors in postoperative patients of biliary atresia. Here, we present a 52-year-old woman who underwent Kasai portoenterostomy for biliary atresia type Ⅲ at the age of 110 days. She was asymptomatic for over 30 years, and birthed three normal babies. Then she suffered from repeated cholangitis due to multiple hepatolithiasis since age 50. A lithotripsy via Roux-en-Y limb was performed but failed due to hepatic hilum strictures. Finally, she underwent living donor liver transplantation. Endoscopic lithotripsy and hepatectomy for hepatolithiasis often fail in biliary atresia patients due to unresolvable intrahepatic or hilar bile duct stenosis and liver dysfunction. Therefore, we consider that liver transplantation is curative and strongly recommended for symptomatic hepatolithiasis as a late complication after biliary atresia surgery.
