Abstract
N6-methyladenosine (m6A) is an RNA modification involved in RNA processing and widely found in transcripts. In cancer cells, m6A is upregulated, contributing to their malignant transformation. In this study, we analyzed gene expression and m6A modification in cancer tissues, ducts, and acinar cells derived from pancreatic cancer patients using MeRIP-seq. We found that dozens of RNAs highly modified by m6A were detected in cancer tissues compared with ducts and acinar cells. Among them, the m6A-activated mRNA TCEAL8 was observed, for the first time, as a potential marker gene in pancreatic cancer. Spatially resolved transcriptomic analysis showed that TCEAL8 was highly expressed in specific cells, and activation of cancer-related signaling pathways was observed relative to TCEAL8-negative cells. Furthermore, among TCEAL8-positive cells, the cells expressing the m6A-modifying enzyme gene METTL3 showed co-activation of Notch and mTOR signaling, also known to be involved in cancer metastasis. Overall, these results suggest that m6A-activated TCEAL8 is a novel marker gene involved in the malignant transformation of pancreatic cancer.

Abstract
PURPOSE/OBJECTIVE(S) Palliative radiotherapy is an effective and commonly used treatment for pain relief in metastatic cancer patients. This study aimed to classify the patients to predict their response to palliative radiotherapy. MATERIALS/METHODS This study used the data from our single-center, prospective observational study (UMIN000044984), which included all patients undergoing palliative radiotherapy for the painful tumor, except for postoperative setting or brain metastases. The eligibility criteria were as follows: (1) numerical rating scale (NRS) was two or more before treatment, and (2) underwent palliative radiotherapy between August 2021 and September 2022. Questionnaires for pain site, NRS, and presence/dose of opioids were obtained before, on the last day of treatment, two weeks later, one month later, three months later, and every three months after that. Patients with severe performance status (PS) were contacted by telephone. Pain response was defined to reduce NRS 2 or more at the treated site without an analgesic increase. The primary outcome was the response rate within three months of the treatment. We used multivariable logistic regression to find the independent prognostic factors for the response based on the following covariates: age, sex, PS, body mass index, NRS, history of radiotherapy, treated site, radiographic features (lytic/sclerotic/mixed), metastatic complication, presence/dose of opioids, bone-modifying agents, radiation dose, type of primary tumor, radiosensitivity, number of metastases, and days from diagnosis to treatment. A classification model was created using significant factors, and response rates were calculated for each class. Statistical significance was defined as P<0.05. RESULTS Among 488 targets of 300 patients registered, 366 targets of 261 patients met the criteria. The median age was 65 years, 44% were female, and PS (0/1/2/3/4) was 6/63/18/9/4%. The major type of tumor was gastrointestinal (32%), lung (19%), and breast (12%). Bone metastases were 75% at treated sites. Opioids were used by 72%, BMA was 27%, and chemotherapy was 50%. Re-irradiation rate was 22%. With a median follow-up of 5.8 months, 113 patients were alive, 129 had died, and 20 were lost follow-up. The average NRS was reduced from 6.1 to 3.1 from pretreatment to 3 months later per evaluable 232 targets, resulting in a pain relief rate of 60%. Opioids use (P<0.001) and re-irradiation (P<0.001) were significant factors of poor response in multivariate analysis. In our classification model, 89 targets were classified as class 1 (no opioids & no irradiation history), 211 were class 2 (other than class 1 and 3), and 66 were class 3 (opioids & re-irradiation), were 75/61/36% (P<0.001) of response rate. The 6-month cumulative pain progression rate was 12/22/32% (P<0.001), respectively. CONCLUSION Palliative radiotherapy is highly effective for patients with painful tumors especially for those without previous irradiation history or use of opioids.

Abstract
An international project on the human genome revealed that various RNAs (e.g., messenger RNAs, microRNAs, and long noncoding RNAs [lncRNAs] and their subclass circular RNA [circRNA)) are involved in the pathogenesis of different human diseases, including cancer. Recent studies have highlighted the critical roles of lncRNAs and circRNA in pancreatic ductal adenocarcinoma (PDAC), especially in the epithelial–mesenchymal transition, a phenomenon regulating cancer metastasis. Growing research in this field has indicated that the tertiary structure of lncRNAs supposedly regulates biological function via RNA–RNA or RNA–protein associations, aiding early diagnosis and therapy selection for various diseases, including cancer. Here we describe the emerging roles of ncRNAs in PDAC and highlight how these ncRNAs can be used to detect and control this intractable cancer.

Abstract
We compare two approaches to using information about the signs of structural shocks at specific dates within a structural vector autoregression (SVAR): imposing "narrative restrictions" (NR) on the shock signs in an otherwise set-identified SVAR; and casting the information about the shock signs as a discrete-valued "narrative proxy" (NP) to point-identify the impulse responses. The NP is likely to be "weak" given that the sign of the shock is typically known in a small number of periods, in which case the weak-proxy robust confidence intervals in Montiel Olea, Stock, and Watson are the natural approach to conducting inference. However, we show both theoretically and via Monte Carlo simulations that these confidence intervals have distorted coverage-which may be higher or lower than the nominal level-unless the sign of the shock is known in a large number of periods. Regarding the NR approach, we show that the prior-robust Bayesian credible intervals from Giacomini, Kitagawa, and Read deliver coverage exceeding the nominal level, but which converges toward the nominal level as the number of NR increases.

Abstract
One-carbon (1C) metabolism plays a key role in biological functions linked to the folate cycle. These include nucleotide synthesis; the methylation of DNA, RNA, and proteins in the methionine cycle; and transsulfuration to maintain the redox condition of cancer stem cells in the tumor microenvironment. Recent studies have indicated that small therapeutic compounds affect the mitochondrial folate cycle, epitranscriptome (RNA methylation), and reactive oxygen species reactions in cancer cells. The epitranscriptome controls cellular biochemical reactions, but is also a platform for cell-to-cell interaction and cell transformation. We present an update of recent advances in the study of 1C metabolism related to cancer and demonstrate the areas where further research is needed. We also discuss approaches to therapeutic drug discovery using animal models and propose further steps toward developing precision cancer medicine.

Abstract
Exosomes (EXs), a type of extracellular vesicles secreted from various cells and especially cancer cells, mesenchymal cells, macrophages and other cells in the tumor microenvironment (TME), are involved in biologically malignant behaviors of cancers. Recent studies have revealed that EXs contain microRNAs on their inside and express proteins and glycolipids on their outsides, every component of which plays a role in the transmission of genetic and/or epigenetic information in cell-to-cell communications. It is also known that miRNAs are involved in the signal transduction. Thus, EXs may be useful for monitoring the TME of tumor tissues and the invasion and metastasis, processes that are associated with patient survival. Because several solid tumors secrete immune checkpoint proteins, including programmed cell death-ligand 1, the EX-mediated mechanisms are suggested to be potent targets for monitoring patients. Therefore, a companion therapeutic approach against cancer metastasis to distant organs is proposed when surgical removal of the primary tumor is performed. However, EXs and immune checkpoint mechanisms in pancreatic cancer are not fully understood, we provide an update on the recent advances in this field and evidence that EXs will be useful for maximizing patient benefit in precision medicine.

Abstract
Since the infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was reported in China during December 2019, the coronavirus disease 2019 (COVID-19) has spread on a global scale, causing the World Health Organization (WHO) to issue a warning. While novel vaccines and drugs that target SARS-CoV-2 are under development, this review provides information on therapeutics which are under clinical trials or are proposed to antagonize SARS-CoV-2. Based on the information gained from the responses to other RNA coronaviruses, including the strains that cause severe acute respiratory syndrome (SARS)-coronaviruses and Middle East respiratory syndrome (MERS), drug repurposing might be a viable strategy. Since several antiviral therapies can inhibit viral replication cycles or relieve symptoms, mechanisms unique to RNA viruses will be important for the clinical development of antivirals against SARS-CoV-2. Given that several currently marketed drugs may be efficient therapeutic agents for severe COVID-19 cases, they may be beneficial for future viral pandemics and other infections caused by RNA viruses when standard treatments are unavailable.

Abstract
Abstract:The main purpose of an automatic health testing system (AMHTS) has changed from early detection to primary prevention. Health-risk appraisal is now widely available as a tool of health education aiming at the modification of unhealthy lifestyles. However, the opportunity to offer appropriate health education was less frequent for those who had no particular findings during AMHTS. The results of an AMHTS should be evaluated from the viewpoint of health-risk appraisal, because the system is expected to supply useful information regarding one’s lifestyle. Our system consists of two health-risk appraisal subsystems. One subsystem estimates the degree of improvement in medical indicators after a patient’s lifestyle has been modified. The other subsystem predicts the occurrence of abnormal findings in medical indicators. These health-risk appraisal subsystems provide patients with information about their health-risks, based on their AMHTS results. Our health-risk appraisal subsystems should play an important role in future health education through the application of ordinary AMHTS.

Abstract
Although it has been reported that populations of the Japanese dojo loach Misgurnus anguillicaudatus (Cypriniformes: Cobitidae) belong to two distinct mitochondrial (mt)DNA (Type I and Type II), the taxonomic status of the species remains unresolved. To address this question, nuclear DNA and morphological analyses were performed on M. anguillicaudatus population in the Nakaikemi Wetland, where Type I and Type II lineages are sympatric. Results suggest the existence of a cryptic species (Type I) within the Japanese dojo loach.

Abstract
The plasma 1,25-(OH)2VD3 level in Fanconi syndrome was low but rose rapidly following the administration of 1 alpha-OHVD3. 1 alpha-OHVD3 was administered to 6 patients with different types of Fanconi syndrome. The effect of 1 alpha-OHVD3 proved to be 200-250 times as great as that of vitamin D2. From our results it was suggested that Ca malabsorption due to failure of 1 alpha-hydroxylation of vitamin D in the kidney, together with renal tubular acidosis and hypophosphatemia, is involved in the pathogenesis of the rickets of Fanconi syndrome.

Abstract
Chemotherapy improves the outcome of cancer treatment, but patients are sometimes forced to discontinue chemotherapy or drop out of a clinical trial due to adverse effects, such as gastrointestinal disturbances and suppression of bone marrow function. The objective of this study was to evaluate the safety and effectiveness of a mushroom product, active hexose correlated compound (AHCC), on chemotherapy-induced adverse effects and quality of life (QOL) in patients with cancer. Twenty-four patients with cancer received their first cycle of chemotherapy without AHCC and then received their second cycle with AHCC. During chemotherapy, we weekly evaluated adverse effects and QOL via a blood test, EORTC QLQ-C30 questionnaire, and DNA levels of herpes virus type 6 (HHV-6) in saliva. The DNA levels of HHV-6 were significantly increased after chemotherapy. Interestingly, administration of AHCC significantly decreased the levels of HHV-6 in saliva during chemotherapy and improved not only QOL scores in the EORTC QLQ-C30 questionnaire but also hematotoxicity and hepatotoxicity. These findings suggest that salivary HHV-6 levels may be a good biomarker of QOL in patients during chemotherapy, and that AHCC may have a beneficial effect on chemotherapy-associated adverse effects and QOL in patients with cancer undergoing chemotherapy.

Abstract
We study the nonequilibrium dynamics of a coherently split one-dimensional Bose gas by measuring the full probability distribution functions of matter-wave interference. Observing the system on different length scales allows us to probe the dynamics of excitations on different energy scales, revealing two distinct length-scale-dependent regimes of relaxation. We measure the crossover length scale separating these two regimes and identify it with the prethermalized phase-correlation length of the system. Our approach enables a direct observation of the multimode dynamics characterizing one-dimensional quantum systems.

Abstract
BACKGROUND As there is only one skin procurement organization in Japan the Japan Skin Bank Network (JSBN), all skin grafts procured in Japan are sent by a commercialized delivery system. Preliminarily, bottles containing saline were transported in a cardboard box using a so-called "cooled home delivery service" using a truck with a refrigerated cargo container. During transportation the temperature in the cardboard box increased to 18°C in summer and decreased to -5°C in winter. For these reasons, we investigated whether a newly developed container "Medi Cube" would be useful to transport skin grafts. OBJECTIVES Four bottles with a capacity of 300 mL containing 150 mL of saline in a Medi Cube container were transported from Osaka to the JSBN in Tokyo between 4 PM and 10 AM using a commercialized cooled home delivery service. Two bottles were transported in a Medi Cube container without phase change materials (PCM) in winter and summer, respectively. Another two bottles were transported in the Medi Cube with PCMs in winter. The temperatures inside saline, inside a transportation container, and outside the container, and air temperature were monitored continuously with a recordable thermometer. RESULTS The temperatures inside saline and inside a Medi Cube container were maintained between 3 and 6°C, even when the temperature outside the container increased during parking. The temperature inside a Medi Cube container without PCM decreased to -3°C when the inside of the cargo container was overcooled in winter. However, the temperatures inside saline and inside a Medi Cube container with PCM were between 3 and 6°C, even when the temperature outside the container decreased to below 0°C in winter. CONCLUSION A Medi Cube container with PCM provided a safe, easy, and cost-effective method for overnight transportation of skin grafts.

Abstract
BACKGROUND AND STUDY AIMS We compared the performance efficiency of a newly developed small-caliber colonoscope (PCF-PQ260 L) with passive bending, high force transmission, and an outer diameter of 9.2 mm with that of a standard colonoscope, in female and male patients, particularly with regard to passage through acute angulations or into the proximal colon. PATIENTS AND METHODS A total of 330 patients were randomly allocated to undergo small-caliber (n = 164) or standard (n = 166) colonoscopy. The patients were assessed for pain using a visual analogue scale (0 = none, 100 = extremely painful), and for cecal intubation, withdrawal time, difficulty of colonoscopy, dosage and level of sedation used, and any complications. RESULTS Median maximum pain and overall pain during colonoscopy were significantly lower in the small-caliber group than in the standard group in women (25 vs. 45, P < 0.001 and 15 vs. 26, P = 0.001, respectively), whereas no significant differences were seen in men (8 vs. 10, P = 0.103 and 16 vs. 20, P = 0.166, respectively). Furthermore, no significant differences were seen between groups in cecal intubation rate or time to cecum in all patients or by sex. CONCLUSIONS Use of the small-caliber colonoscope reduced pain in female patients, but offered no advantage over standard colonoscopy in male patients. The performance of the small-caliber colonoscope was equivalent to that of the standard colonoscope in terms of cecal intubation rate and time to cecum, regardless of the sex of the patient.

Abstract
Carcinogenesis and cancer progression, driven by mutations in oncogenes and tumor-suppressor genes, result in biological differences between normal and cancer cells in various cellular processes. Specific genes and signaling molecules involved in such cellular processes may be potential therapeutic targets of agents that specifically interact with the key factors in cancer cells. Increased glucose uptake is fundamental to many solid tumors and well associated with increases in glycolysis and the overexpression of glucose transporters (GLUTs) such as GLUT1 and GLUT3 at the plasma membrane. Here, we used cell-based screening to identify glycogen synthase kinase-3β (GSK-3β) inhibitors that selectively target GLUT3-expressing tumorigenic HeLa cell hybrids as compared with non-tumorigenic hybrids that express GLUT1 alone. The GSK-3 inhibitors as well as GSK-3β RNAi suppressed GLUT3 expression at the level of transcription, leading to apoptosis. This suppression was associated with NF-κB in a p53-independent manner. Furthermore, GSK-3 inhibitors exhibited a synergistic effect with anticancer agents such as adriamycin and camptothecin in GULT3-overexpressing colon cancer cells, but little effect in non-producing A431 cells. These results suggest a potential use of GSK-3 inhibitors to selectively kill cancer cells that overexpress GLUT3.

Abstract
345 Background: Resection of biliary tract cancer, employing pancreatoduodenectomy and major hepatectomy, is highly aggressive. Thus, postoperative gemcitabine cannot be administered employing a routine dosage protocol. We theorized that a 3-weekly protocol (days 1 and 8, every 3 weeks) of gemcitabine as adjuvant chemotherapy would be superior to the usually administered 4-weekly protocol (days 1, 8, and 15 every 4 weeks). Methods: The outcomes of 6 cycles of the 4-weekly protocol and 9 cycles of the 3-weekly protocol were compared in a prospective randomized clinical setting. The primary endpoint was the treatment completion rate, while secondary endpoints were adverse events and recurrence-free survival. Results: We enrolled a total of 27 patients. Only two patients (14%) on the 4-weekly protocol and three (23%) on the 3-weekly protocol (p=0.8099) completed treatment with no omissions and/or dose modifications. Most of the remaining patients (70%) experienced grade 3/4 neutropenia. Relative dose intensities were 72% and 78%, respectively, with the 4-weekly and 3-weekly protocols. Recurrence-free survival rates did not differ significantly between the two protocols. Conclusions: Contrary to our hypothesis, the 3-weekly protocol did not produce superior results in terms of completion, adverse events or recurrence-free survival rates as compared to the standard 4-week protocol.

Abstract
Intraductal papillary-mucinous neoplasm (IPMN) of the pancreas presents in various histopathological stages from benign to malignant lesions. The differentiation between benign and malignant IPMN is important in order to determine the treatment of the patients. However, pre-operative differentiation remains difficult. The aim of this study was to assess the utility of 2-[18F] fluoro-2-deoxy-D-glucose positron emission tomography (FDG-PET) in pre-operative differentiation of benign and malignant IPMN of the pancreas. In the present study we prospectively investigated 29 patients who underwent CT, FDG-PET, and surgery for IPMNs, followed by histopathological examination. The maximum standardized uptake value (SUVmax) was determined on FDG-PET, and differentiation of benign from malignant IPMN was tested using various SUVmax cut-off levels and various parameters derived from the CT. SUVmax was found to be significantly higher in malignant IPMNs (4.7+/-3.0) than that in benign IPMNs (1.8+/-0.3, P=0.0011). SUVmax values correlated with the histopathological types of IPMN (adenoma/borderline lesion/carcinoma in situ/invasive carcinoma) (Spearman rank correlation 0.865, P<0.0001). The specificity, sensitivity and accuracy values were best for SUVmax of 2.5 (100, 93, and 96%, respectively). The combination of mural nodule, detected on CT, and SUVmax of 2.5 offered the best diagnosis of malignant IPMN. These results suggest that FDG-PET is useful for differentiation of malignant IPMN of the pancreas, and that it should be performed in combination with other conventional imaging modalities.

Abstract
AIM The safety and efficacy, and the dose-limiting toxicity (DLT) of the chemotherapeutic agent gemcitabine administered in conjunction with radiotherapy in patients with locally advanced pancreatic cancer are not yet established. Here, we evaluated the safety and efficacy, DLT, and maximum tolerated dose of gemcitabine with concurrent radiotherapy in patients with unresectable locally advanced pancreatic cancer. Tumor response and time to progression were also assessed. PATIENTS AND METHODS Patients with previously untreated pancreatic cancer (n = 12) received gemcitabine intravenously on days 1, 8, and 15. Concurrent radiation therapy was initiated on day 1 (40 Gy in 2 Gy/day x 20 fractions, days 1-5, 8-12, 15-19, 22-26). Patients received limited-field irradiation with three-dimensional radiotherapy. Dose escalation included dose levels 1-3 (gemcitabine 400, 600, and 800 mg/m(2)). RESULTS No patient developed DLT in this study. Of the 12 patients, there were 11 sustained responses, 0 partial responses, and 1 progressive disease. Two patients with a sustained response underwent surgery after re-evaluation. The median progression-free survival was 8 months, not including the patients that underwent surgery. CONCLUSION Weekly gemcitabine at a dose of 800 mg/m(2) with concurrent radiation therapy in patients with locally advanced pancreatic cancer was well tolerated. and IAP.

Abstract
A 68-year-old man lost in unconscious and was diagnosed as ruptured hepatocellular carcinoma (HCC) in a local emergency hospital. He was treated by transcatheter arterial embolization, and further investigation revealed simultaneous cancer in rectum. He was referred to our institute, and admitted in June 2005. He underwent lateral segment and S8 partial resection of the liver, cholecystectomy, anterior resection of rectum, and D3 lymphadenectomy in August 2005. Multiple HCC recurrences in the remnant liver appeared in December 2005. He was subsequently treated with transcatheter chemoembolization four times. In May 2006, CT scan revealed multiple metastatic nodules in bilateral lungs with remarkably elevated serum AFP and PIVKA-II. The nodules were diagnosed as lung metastasis of the HCC. Because the lesions grew larger, S-1 was started in February 2007. Diagnostic imaging and tumor markers showed a marked improvement 2 months after S-1 administration, and no recurrence has been found since then. This case illustrates that S-1 may be an effective treatment for HCC with extrahepatic metastasis.

Abstract
Gemcitabine monotherapy is accepted as a standard first-line treatment for locally advanced unresectable or metastatic pancreatic cancer. On another front, S-1 and gemcitabine combination chemotherapy is challenging but promising. We report a long-term survival case of pancreatic cancer with hepatic metastasis after surgical resection treated by S-1 and gemcitabine combination chemotherapy. A 59-year-old woman was diagnosed as locoregionally advanced pancreas head cancer without metastatic disease. Pancreatoduodenectomy with regional lymph node dissection was performed after preoperative chemoradiotherapy. Pathological examination revealed a poorly differentiated adenocarcinoma. A solitary hepatic metastasis was detected by CT imaging one year after the surgery. The patient received 35 courses of S-1 and gemcitabine combination therapy. The metastatic tumor was disappeared, and serum CEA decreased to a normal level. S-1 and gemcitabine combination therapy is not only effective but also well tolerated and safe. This combination therapy should be considered one of selective choices for advanced or metastatic pancreatic cancer.

Abstract
A 69-year-old man with chief complaint of epigastralgia was diagnosed as locally advanced borderline unresectable pancreatic head cancer that involved superior membrane artery (SMA). Gemcitabine (GEM) -based chemoradiotherapy (CRT) was administered for consecutive 3 weeks in the following fashion: continuous twice-a-day accelerated radiotherapy (2 daily fractions of 1.5 Gy, 5 days a week, with a 6-hr minimal interval between fractions) with 3-time weekly intravenous infusions of GEM. Total radiation dose was 45 Gy and GEM was given on days 1, 8 and 15 at dose of 800 mg/m2. After the completion of CRT, the involvement of SMA remained. Next, additional systemic chemotherapy with GEM was performed for 3 weeks in the following fashion: weekly intravenous infusions of GEM at dose of 1,000 mg/m2. Finally, the main tumor and the invasion to SMA were reduced. Surgical resection with negative margins (R0 resection) was performed. Adjuvant chemotherapy with 6 courses of GEM was also performed. The patient has no recurrence, suggesting the efficacy of GEM-based CRT for locally advanced borderline unresectable pancreatic cancer.

Abstract
A 50-year-old woman with epigastric uncomfortable feeling was referred to our hospital. We have diagnosed her as an advanced gallbladder cancer with direct liver invasion and lymph node metastasis of hepatoduodenal ligament by the image analysis, including enhanced abdominal CT, MRI and FDG-PET. Subsequently, we performed operation with cholecystectomy, hepatic segmentectomy of S4a/5, bile duct resection and D2 lymph node dissection, resulted in the curative operation. We additionally performed adjuvant chemotherapy with 6 courses of 800 mg/m2 of gemcitabine (GEM) on days 1, 8 and 15 for every 35 days. No recurrent signs were observed for 33 months after curative operation.

Abstract
Sclerosing epithelioid fibrosarcoma (SEF) is a rare and distinct variant of fibrosarcoma, composed of epithelioid tumor cells arranged in strands, nests, cords, or sheets embedded within a sclerotic collagenous matrix. We report a 39-year-old man with SEF of the liver, which infiltrated the inferior vena cava (IVC). The SEF of the liver was successfully resected, and the infiltrated IVC was also removed together with the liver tumor. Histopathological examination of the tumor showed typical histopathology of SEF. Immunohistochemically, the tumor was positive for vimentin. Recurrence was noted 7 mo after surgery. After chemotherapy, the recurrent tumor was resected surgically, and histopathological examination showed similar findings to those of the primary tumor. To our knowledge, this is the first report of SEF of the liver with tumor invasion of the IVC.

Abstract
It is well-known that self-etching primers can be altered. However, the effects from altered primers on the dentin bond durability have yet to be thoroughly identified. In this study, we examined the effects from 5 altered Liquid A primers in different stages of degradation-where 2-hydroxyethylmethacrylate (HEMA) and 10-methacryloyloxydecyl dihydrogen phosphate (MDP), used in Liquid A primers, were altered by the hydrolysis of the methacryloxy ester portion in the HEMA and MDP-on the hybrid layer's quality and dentin bond durability. The hypothesis was that degradation stages of altered Liquid A primers have no effect on the hybrid layer's quality and on dentin bond durability. Bond strengths, obtained after thermo-cycling, were strongly dependent on the degradation stage of the altered Liquid A primer. Alterations of self-etching primers reduced dentin bond durability and decreased the created hybrid layer's quality.

Abstract
As the North Equatorial Current (NEC)-bifurcation is known to be related to El Niño-Southern Oscillation (ENSO) events, the influence of the position of the NEC bifurcation on transport success of the larval Japanese eel Anguilla japonica was investigated. Using a Lagrangian modelling approach, larval transport was simulated and the relative influence of El Niño and La Niña events and the NEC-bifurcation position on the success of particle transport analysed. The number of particles transported from the NEC to the Kuroshio tended to be lowest during El Niño years, and differences between La Niña and regular years were small. The transport success observed in simulations showed some relationships to annual A. japonica glass eel recruitment to Tanegashima Island over 1993 to 2001, but not in 2002. The study shows that particle tracking simulations can be used to improve knowledge of the oceanic migration of A. japonica but further studies are required, including comparisons with the effects on larval survival of fluctuations in temperature and food availability.
