Abstract
Background Olfactory dysfunction is an increasingly recognised condition, associated with reduced quality of life and major
health outcomes such as neurodegeneration and death. However, translational research in this field is limited by heterogeneity in methodological approach, including definitions of impairment, improvement and appropriate assessment techniques. Accordingly, effective treatments for smell loss are limited. In an effort to encourage high quality and comparable work in this field, among others, we propose the following ideas and recommendations. Whilst the full set of recommendations are outlined in the main document, points include the following:
• Patients with suspected olfactory loss should undergo a full examination of the head and neck, including rigid nasal endoscopy
with small diameter endoscopes.
• Subjective olfactory assessment should not be undertaken in isolation, given its poor reliability.
• Psychophysical assessment tools used in clinical and research settings should include reliable and validated tests of odour
threshold, and/or one of odour identification or discrimination.
• Comprehensive chemosensory assessment should include gustatory screening.
• Smell training can be helpful in patients with olfactory loss of several aetiologies. Conclusions We hope the current manuscript will encourage clinicians and researchers to adopt a common language, and in so doing, increase the methodological quality, consistency and generalisability of work in this field.

Abstract
BACKGROUND/AIM Wilms' tumor 1 (WT1) is a tumor-associated antigen highly expressed in cancer. We examined the safety of WT1-peptide pulsed dendritic cell (WT1-DC) vaccine in combination with chemotherapy in patients with surgically resected pancreatic cancer. PATIENTS AND METHODS Eight patients with resectable pancreatic cancer undergoing surgery either combined with S-1 or S-1 plus gemcitabine therapy were enrolled. Immunohistochemical analysis of WT1 was performed in 34 cases of pancreatic cancer. RESULTS No serious side-effects were observed, except grade I fever in five and grade I reactions at the injection site in all patients. WT1-specific cytotoxic T-lymphocytes were detected in seven patients, and WT1 and human leukocyte antigen class I antigens were positive in all 34 cases. CONCLUSION Our study clarified the safety and potential acquisition of immunity after vaccination targeting WT1. Further efficacy of WT1-DC vaccine to improve prognosis would be determined by a prospective clinical trial for resectable pancreatic cancer.

Abstract
BACKGROUND Hyaluronan (HA) is an important constituent of extracellular matrix (ECM) in the skin, and HA degradation mediated by HYBID (KIAA1199) is suggested to be implicated in facial skin wrinkling in Japanese women. Ethnic difference in skin wrinkle formation is known between Caucasian and Japanese women, but no information is available for the relations of HA and HYBID expression levels with skin wrinkling in Caucasian women. METHODS The skin surface roughness at the eye corner of the Caucasian female subjects was measured, and the skin specimens biopsied from the same areas were subjected to microarray gene analysis, HA staining, and immunohistochemistry for HYBID. RESULTS Among the ECM genes and those related to ECM metabolism, only HYBID expression levels positively correlated with the skin roughness parameters. When the skin sample groups with high expression of HYBID or low expression of HYBID were compared, the HA staining intensity and the ratio of HYBID-immunoreactive cells to total cells in the superficial dermis were significantly reduced and increased in the high-HYBID-expression group compared with the low-HYBID-expression group, respectively. CONCLUSION Our data suggest that like Japanese women, HYBID-mediated reduction of HA in the superficial dermis is involved in the formation of wrinkles in Caucasian women.

Abstract
The minimal ingredients to explain the essential physics of layered copper-oxide (cuprates) materials remains heavily debated. Effective low-energy single-band models of the copper–oxygen orbitals are widely used because there exists no strong experimental evidence supporting multi-band structures. Here, we report angle-resolved photoelectron spectroscopy experiments on La-based cuprates that provide direct observation of a two-band structure. This electronic structure, qualitatively consistent with density functional theory, is parametrised by a two-orbital (\documentclass[12pt]{minimal}

We quantify the orbital hybridisation which provides an explanation for the Fermi surface topology and the proximity of the van-Hove singularity to the Fermi level. Our analysis leads to a unification of electronic hopping parameters for single-layer cuprates and we conclude that hybridisation, restraining d-wave pairing, is an important optimisation element for superconductivity. The essential physics of cuprate superconductors is often described by single-band models. Here, Matt et al. report direct observation of a two-band electronic structure in La-based cuprates.

Abstract
Covered self-expandable metallic stents (CSEMS) may provide palliative drainage for unresectable distal malignant biliary strictures. Laser-cut CSEMS allows easy positioning due to its characteristic of minimal stent shortening. Endoscopic stent removal is sometimes recommended for recurrent biliary obstruction (RBO). However, there are no previous reports of endoscopic removal of laser-cut CSEMS. The current study presents data from 6 patients who were placed a laser-cut CSEMS for unresectable distal malignant biliary strictures, and later endoscopic stent removal was attempted for RBO at the present institute. The duration of stent placement, the procedural success rate, the procedural duration, and accidental complications were evaluated. The mean duration of stent placement was 156±37.9 days (range, 117–205). The procedural success rate was 100%. The mean procedural duration was 11.8±7.5 min (range, 5–24). No complications were reported. Laser-cut CSEMS were safely removed from all patients. The present case report is the first to demonstrate that Endoscopic stent removal of laser-cut CSEMS was safely performed.

Abstract
Lymphadenopathy may be difficult to diagnose using imaging results alone. Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) may help to diagnose and determine the appropriate management of lymphadenopathy. EUS-FNA has been used as a safe and less invasive method for obtaining pathologic specimens from extraluminal lesions using endoscopic ultrasound. The present study evaluated the usefulness of EUS-FNA for lymphadenopathy. Between July 2013 and December 2016, 72 patients undergoing EUS-FNA for lymphadenopathy that could not be diagnosed solely using imaging were included. The present study evaluated the sensitivity, specificity, positive and negative predictive value, overall accuracy, helpfulness in determining the management of lymphadenopathy and EUS-FNA-associated complications. Of the 72 included patients, 8 were diagnosed with benign (inflammatory or reactive) lymphadenopathy. The diagnostic sensitivity, specificity, positive and negative predictive value, and overall accuracy were 95.3, 100, 100, 72.7 and 95.8%, respectively. While EUS-FNA of metastatic nodes identified the origin in the majority of cases, the procedure resulted in a different histopathological diagnosis from the previous image-based diagnosis in 9 patients. Consequently, 2 patients with testicular cancer were administered bleomycin, etoposide, and cisplatin. An individual with GIST was administered imatinib, and a patient with prostate cancer was administered degarelix (antihormon drug). A total of 5 other patients received palliative medicine due to the change in diagnosis. EUS-FNA also helped determine the appropriate cancer management plan in other patients; specifically, based on the cytology of the metastatic lymph node, EUS-FNA helped determine the cancer stage, and to identify recurrence or the primary cancer from which tissue could not be collected. No EUS-FNA-associated symptoms were reported. To conclude, the present study suggested that EUS-FNA of suspected metastatic lymph nodes appears safe and useful for cancer staging and diagnosing recurrence. It may also useful for diagnosing patients whose collection of samples from the original cancer appeared impractical. EUS-FNA for lymphadenopathy that may not be diagnosed with imaging alone may assist in diagnosis and help to determine the appropriate management strategy.

Abstract
Cabotegravir (CAB, S/GSK1265744) is an investigational second-generation integrase strand transfer inhibitor (INSTI) with a chemical structure similar to dolutegravir. CAB is under development as a long-acting injectable formulation for treatment of HIV-1 infection and for pre-exposure prophylaxis. We conducted an in vitro passage study of raltegravir- or elvitegravir-resistant signature mutants in the presence of CAB to characterize the resistance profile of this drug. During passage with Q148H virus, G140S arose by day 14, followed by G149A and C56S. Using site-directed mutagenesis, we obtained HIV molecular clones containing mutations encoding C56S and G149A in the integrase-coding region. Those substitutions were characterized in vitro as INSTI-resistance-associated secondary resistance mutations. Signature mutant viruses G140S/Q148H in which C56S and G149A were added acquired further INSTI resistance in conjunction with diminished integration activity, which yielded slower growth under drug-free conditions.

Abstract
BACKGROUND/PURPOSE Previous studies have reported decreased dermal echogenicity and increased skin oxidative stress in overweight males. However, it is unknown whether these skin parameters of overweight and obese people are similar to those of individuals exhibiting a normal body weight following weight loss. The purpose of this study was to (1) compare the changes in the dermal structure parameters and levels of skin oxidative stress before and after weight loss in overweight and obese people in Japan and (2) to clarify how these aspects changed when body weight would be reduced to normal body weight. METHODS Male volunteers with a body mass index of ≥25 kg/m2 were recruited. The dermal structure was visualized and dermal echogenicity and thickness were measured using ultrasound scanners. The mRNA expression level of heme oxygenase-1 in the hair follicles was quantitatively analyzed as a marker of skin oxidative stress. RESULTS When overweight individuals in their 20s to 30s reduced their weight to normal, decreased dermal thickness in the abdominal region was observed in 50% of the subjects; however, no increase in dermal echogenicity was observed. A decrease in dermal thickness and an increase in dermal echogenicity in the thighs was observed in 83.3% of the subjects. No decrease in the level of dermal oxidative stress was observed. CONCLUSION The dermal structure in the thighs of overweight young individuals can be improved to the level of the structure in those of normal body weight individuals following weight loss.

Abstract
Ubiquitin chains are formed with 8 structurally and functionally distinct polymers. However, the functions of each polyubiquitin remain poorly understood. We developed a polyubiquitin-mediated fluorescence complementation (PolyUb-FC) assay using Kusabira Green (KG) as a split fluorescent protein. The PolyUb-FC assay has the advantage that monoubiquitination is nonfluorescent and chain-specific polyubiquitination can be directly visualized in living cells without using antibodies. We applied the PolyUb-FC assay to examine K33-linked polyubiquitin. We demonstrated that SQSTM1/p62 puncta colocalized with K33-linked polyubiquitin and this interaction was modulated by the ZRANB1/TRABID-K29 and -K33 linkage-specific deubiquitinase (DUB). We further showed that the colocalization of K33-linked polyubiquitin and MAP1LC3/LC3 (microtubule associated protein 1 light chain 3) puncta was impaired by SQSTM1/p62 deficiency. Taken together, these findings provide novel insights into how atypical polyubiquitin is recruited by SQSTM1/p62. Finally, we developed an inducible-PolyUb-FC system for visualizing chain-specific polyubiquitin. The PolyUb-FC will be a useful tool for analyzing the dynamics of atypical polyubiquitin chain generation.

Abstract
Summary
Aim: To examine the utility of 2'-[18F]-fluoro-2'-deoxy-D-glucose positron emission tomography (FDG-PET) for detecting multiple primary cancers (MPC) in patients with hypopharyngeal cancer (HPC). Patients, methods: Seventy patients with HPC underwent FDGPET to determine the staging. Routine clinical examinations were carried out, including computed tomography (CT), magnetic resonance imaging (MRI), ultrasound (US), and oesophagealgastroduodenoscopy (EGDS). The detection rate of synchronous and metachronous cancer was calculated based on FDG-PET alone or FDG-PET combined with clinical routine examination. Sensitivity, specificity, positive predictive values (PPV), negative predictive values (NPV), and accuracy were used to diagnose oesophageal cancer using FDG-PET. Results: Of the 70 patients, 12 (17.1%) had 15 synchronous tumours, and 2 of the 58 remaining patients (3.4%) had metachronous tumours. Oesophageal cancer was discovered most frequently: superficial type (n = 6), advanced type (n = 4). On a per-patient basis, 11 of 12 patients (91.6%) were diagnosed with synchronous tumours, and on a per-lesion basis, 12 of 15 lesions (80.0%) were detected by FDG-PET. The sensitivity, specificity, accuracy, PPV, and NPV of FDG-PET regarding oesophageal cancer were 70%, 100%, 95.7%, 100%, and 95.2% respectively. Three of the six superficial types were positive on FDG-PET. Both of the metachronous tumour lesions were detected by FDG-PET. Conclusion: FDG-PET is useful for estimating the MPC in HPC patients. Since 3 of 10 synchronous oesophageal cancer were missed with PET alone, a combination with EGDS should be considered to exclude synchronous oesophageal cancer.

Abstract
BACKGROUND Endometriosis is a gynaecological disease exhibiting severe pelvic pain, but the mechanism of pain production remains unknown. Bradykinin (BK) is known as an inflammatory mediator, and shows elevated levels in inflammatory diseases such as rheumatoid arthritis. In the present study, we evaluated whether BK is involved in endometriosis-related pain. METHODS Endometriotic lesions were used for immunohistochemistry. Primary cultures of endometriotic stromal cells (ESC) were stimulated with IL-1β and/or BK. Quantitative RT-PCR was used to evaluate the mRNA expressions of BK receptors (BKR) and endothelin-1 in ESC. The concentration of endothelin-1 in cystic fluid of endometrioma or non-endometrioma was measured with ELISA. The conditioned medium of ESC stimulated with IL-1β and/or BK was injected intraplantarly in mice, and evaluated whether pain-related licking behaviour was elicited. RESULTS The expressions of BK and BKR in endometriotic lesions were observed by immunohistochemistry. In vitro experiments showed that IL-1β induced BKR-B1 and B2 on ESC. Activation of these receptors by BK significantly induced endothelin-1 expression in ESC, which was negated completely by HOE-140, a BKR-B2 antagonist. The cystic fluid of endometrioma contained higher amount of endothelin-1 compared to non-endometrioma. Intraplantar injection of the conditioned medium of ESC treated with IL-1β and BK significantly induced licking behaviour, which was suppressed with BQ-123, an endothelin type-A receptor antagonist. CONCLUSIONS The present study demonstrated the presence and the function of the BK axis in endometriosis, and established a potential new therapy target for endometriosis-related pain. SIGNIFICANCE The present study demonstrated (1) the presence and the function of the BK system in endometriosis, (2) activation of BKR induced endothelin-1 in endometriotic lesion and (3) blocking endothelin-1 was effective to decrease pain.

Abstract
BACKGROUND AND PURPOSE Preoperative hemodynamic impairment in the affected cerebral hemisphere is associated with the development of cerebral hyperperfusion following carotid endarterectomy. Cerebral oxygen extraction fraction images generated from 7T MR quantitative susceptibility mapping correlate with oxygen extraction fraction images on positron-emission tomography. The present study aimed to determine whether preoperative oxygen extraction fraction imaging generated from 7T MR quantitative susceptibility mapping could identify patients at risk for cerebral hyperperfusion following carotid endarterectomy. MATERIALS AND METHODS Seventy-seven patients with unilateral internal carotid artery stenosis (≥70%) underwent preoperative 3D T2*-weighted imaging using a multiple dipole-inversion algorithm with a 7T MR imager. Quantitative susceptibility mapping images were then obtained, and oxygen extraction fraction maps were generated. Quantitative brain perfusion single-photon emission CT was also performed before and immediately after carotid endarterectomy. ROIs were automatically placed in the bilateral middle cerebral artery territories in all images using a 3D stereotactic ROI template, and affected-to-contralateral ratios in the ROIs were calculated on quantitative susceptibility mapping-oxygen extraction fraction images. RESULTS Ten patients (13%) showed post-carotid endarterectomy hyperperfusion (cerebral blood flow increases of ≥100% compared with preoperative values in the ROIs on brain perfusion SPECT). Multivariate analysis showed that a high quantitative susceptibility mapping-oxygen extraction fraction ratio was significantly associated with the development of post-carotid endarterectomy hyperperfusion (95% confidence interval, 33.5-249.7; P = .002). Sensitivity, specificity, and positive- and negative-predictive values of the quantitative susceptibility mapping-oxygen extraction fraction ratio for the prediction of the development of post-carotid endarterectomy hyperperfusion were 90%, 84%, 45%, and 98%, respectively. CONCLUSIONS Preoperative oxygen extraction fraction imaging generated from 7T MR quantitative susceptibility mapping identifies patients at risk for cerebral hyperperfusion following carotid endarterectomy.

Abstract
A 42‐year‐old man with schizophrenia was referred to our hospital after 2 weeks of worsening fatigue. His hemoglobin level was 2.8 g/dL owing to folic acid deficiency stemming from alcohol abuse and consumption of unbalanced meals. We induced behavioral changes in the patient by motivational interviewing. We had direct methodical conversations with medical staff involved with the patient as well as his family, and established new social support for him as well as public assistance. These have resulted in the patient maintaining a favorable lifestyle ever since.

Abstract
BACKGROUND ABO and its paralogues, such as A3GALT2 and GGTA1, encoding α1,3-Gal(NAc) transferases, belong to the glycosyltransferase 6 (GT6) gene family. We have developed an alternative method for the identification of species based on sequence variations within the GT6 gene family, which is applicable to degraded DNA. METHODS/MATERIALS DNA samples prepared from control mammalian species, together with an unknown sample, were polymerase chain reaction (PCR)-amplified using one universal primer pair targeting the sequences in the last coding exons of the GT6 gene family, yielding 141-bp products derived from those multiple loci. After cloning, sequence determination and Basic Local Alignment Search Tool analysis, phylogenetic trees were constructed. RESULTS Comparison of the sequences obtained with those references showed good concordance with each of the starting species of mammals. This system was able to identify 'mouse' or 'rodent' as the origin of the unknown sample. CONCLUSION For the identification of species, genotyping of ABO and its homologues would be applicable for the analysis of degraded DNA samples. Although the method employed in this study is likely valid for mammals, it would not be suitable for birds, fish and reptiles. It may be possible to improve the present method for use with other species by employing an alternative universal primer set.

Abstract
Canine histiocytic sarcoma (HS) is an aggressive and highly metastatic tumor. Previously, the kinase inhibitor dasatinib was shown to have potent growth inhibitory activity against HS cells in vitro, possibly via targeting the EPHA2 receptor. Here, the in vivo effect of dasatinib in HS cells was investigated using a xenograft mouse model. Moreover, the expression status of EPHA2 was examined in six HS cell lines, ranging from insensitive to highly sensitive to dasatinib. In the HS xenograft mouse model, dasatinib significantly suppressed tumor growth, as illustrated by a decrease in mitotic and Ki67 indices and an increase in apoptotic index in tumor tissues. On Western blot analysis, EPHA2 was only weakly detected in all HS cell lines, regardless of sensitivity to dasatinib. Dasatinib likely results in the inhibition of xenograft tumor growth via a mechanism other than targeting EPHA2. The findings of this study suggest that dasatinib is a targeted therapy drug worthy of further exploration for the treatment of canine HS.

Abstract
National surveys were conducted in Japan to assess the current practices for circulatory management of extremely-low-birth-weight infants (ELBWIs) in acute phases. Approximately 80 and 100 institutions were surveyed in 2006 and 2011, respectively. Echocardiography was identified as an important diagnostic tool at 95% of the surveyed institutions. Furthermore, 74% of the institutions survey in 2011 used vasodilator agents. In 2011, the mean velocity of circumferential fiber shortening (mVcfc) and left ventricular end-systolic wall stress (ESWS) were used by 60% of the surveyed institutions to evaluate the relationship between afterload of the left ventricle and left ventricular contractility. Overall, the data collected from these national surveys clarified the current practices for circulatory management of ELBWIs in Japan, particularly the use of echocardiography and cardiovascular agents, including catecholamines and vasodilators.

Abstract
Regulatory T cells (Tregs ) control immune responses by suppressing various inflammatory cells. Tregs in newborn babies may play an important role in preventing excessive immune responses during their environmental change. We examined the number and phenotype of Tregs during the neonatal period in 49 newborn babies. Tregs were characterized by flow cytometry using cord blood (CB) and peripheral blood (PB) from the early (7-8 days after birth) and late (2-4 weeks after birth) neonatal periods. CD4+ forkhead box protein 3 (FoxP3+ ) T cells were classified into resting Tregs (CD45RA+ FoxP3low ), activated Tregs (CD45RA- FoxP3high ) and newly activated T cells (CD45RA- FoxP3low ). Compared with CB and PB during the late neonatal period, the percentage of Tregs and all Treg subpopulations in the CD4+ lymphocyte population were increased significantly during the early neonatal period. Furthermore, the proportion and absolute number of activated Tregs were increased markedly compared with other Treg subpopulations, such as resting Tregs and newly activated T cells (non-Tregs ), in the early neonatal period. Increased Tregs concomitantly expressed the suppressive molecule cytotoxic T lymphocyte antigen-4 (CTLA-4). The up-regulated expression of chemokine receptor 4 (CCR4) and down-regulated expression of CCR7 were also observed in expanded Tregs . When cord blood cells were cultured in vitro with CD3 monoclonal antibodies (mAb) for 5 days, CD4+ CD45RA- FoxP3high cells were increased significantly during the culture. Thus, the presence of increased activated Tregs in early neonates may play an important role in immunological regulation by suppressing excessive T cell activation caused by the immediate exposure to ubiquitous antigens after birth.

Abstract
Pancreatic ductal adenocarcinoma (PDA) is characterized by a very poor prognosis, despite novel chemotherapeutic treatments. Moreover, the majority of PDA patients with complete surgical resection show recurrence within 5 years of resection. Therefore, new targeted cancer vaccines are urgently needed to extend PDA patient survival. The Wilms' tumor 1 (WT1) antigen was identified as an excellent antigen in a list of 75 tumor-associated antigens by a National Cancer Institute prioritization project based on several factors, such as therapeutic function. WT1-targeted cancer vaccines are not only efficient in the regression of PDA cells but also angiogenesis and immune suppressive cells, such as myeloid-derived suppressor cells (MDSCs), in the PDA microenvironment. Moreover, WT1 is increased in PDA cells; thus, WT1 may represent an effective therapeutic target for PDA, resulting in a survival benefit for PDA patients. A novel WT1 peptide with increased immunogenicity was developed and used in clinical trials to induce more successful clinical results. This review summarizes the clinical trials of PDA patients receiving WT1-targeted cancer vaccines.

Abstract
UNLABELLED Root amputation, extraction of a single tooth, bone loss or severe tooth mobility, and an unclosed wound were significantly associated with increased risk of developing medication-related osteonecrosis of the jaw (MRONJ). We recommend a minimally traumatic extraction technique, removal of any bone edges, and mucosal wound closure as standard procedures in patients receiving bisphosphonates. INTRODUCTION Osteonecrosis of the jaws can occur following tooth extraction in patients receiving bisphosphonate drugs. Various strategies for minimizing the risk of MRONJ have been advanced, but no studies have comprehensively analyzed the efficacy of factors such as primary wound closure, demographics, and drug holidays in reducing its incidence. The purpose of this study was to retrospectively investigate the relationships between these various risk factors after tooth extraction in patients receiving oral bisphosphonate therapy. METHODS Risk factors for MRONJ after tooth extraction were evaluated using univariate and multivariate analysis. All patients were investigated with regard to demographics; type and duration of oral bisphosphonate use; whether they underwent a discontinuation of oral bisphosphonates before tooth extraction (drug holiday), and the duration of such discontinuation; and whether any additional surgical procedures (e.g., incision, removal of bone edges, root amputation) were performed. RESULTS We found that root amputation (OR = 6.64), extraction of a single tooth (OR = 3.70), bone loss or severe tooth mobility (OR = 3.60), and an unclosed wound (OR = 2.51) were significantly associated with increased risk of developing MRONJ. CONCLUSIONS We recommend a minimally traumatic extraction technique, removal of any bone edges, and mucosal wound closure as standard procedures in patients receiving bisphosphonates. We find no evidence supporting the efficacy of a pre-extraction short-term drug holiday from oral bisphosphonates in reducing the risk of MRONJ.
