Abstract
Nanopore-based diagnostic systems are a promising tool for counting viruses in a specimen one by one. However, despite intensive R&D efforts, it remains difficult to recognize virus subtypes by nanopore devices. We thus propose a novel diagnostic system that combines a specialized virus recognition procedure with a nanopore detection procedure. This recognition procedure consists of three steps: 1) capture target viruses using specific probes for recognition; 2) release captured targets; and 3) detect released targets by nanopore. Proof-of-concept tests are conducted using avidin-modified fluorescent particles (as a model for viruses) and biotin-modified alkane thiol (as a model for probes). The avidin-modified particles are confirmed to be captured on electrode by biotin-modified probes and then, the particles are electrochemically released from the electrode. Consequently, the released particles are successfully detected by nanopore devices. Furthermore, the concept is also proved by using human influenza viruses (H1N1, A/PR/8/34) and sugar chain (6'-sialyllactose)-modified probes. This suggests that our concept is applicable to various infectious diseases by changing probes (ligands).

Abstract
Abstract
Background
Calcified nodule (CN) in coronary artery is known to be a significant factor for stent underexpansion, however, its baseline characteristics and long-term prognosis is unclear.
Method
421 consecutive severe calcified lesions (Defined as maximum calcium arc >180 degrees) which underwent optical coherence tomography (OCT)-guided percutaneous coronary intervention (PCI) were analyzed between January 2013 and December 2017. We investigated baseline characteristics and OCT parameter (maximum arc of calcium, maximum thickness of calcium, and length of calcium) and long-term clinical outcome (Major adverse cardiac event (MACE), any cause of death, acute myocardial infarction (AMI) and target vessel failure (TVF)). Median follow up period was 33.7 months.
Result
CN was seen in 22.3% (94 lesions) of all severe calcified lesions. Baseline characteristics and OCT parameters were significantly different in CN and non-CN groups (Hemodialysis; 23.6% vs. 14.1%, p=0.03, Multivessel Disease; 57.4% vs. 44.6, p=0.03, maximum arc of calcium; 305.4 vs. 286.1, p=0.02, maximum thickness of calcium (μm); 1206.2 vs 1123.8, p=0.01, length of calcium (mm); 24.6 vs. 19.0, p=0.01). CN lesions was strongly associated poor long-term clinical outcome (MACE; 50.5% vs. 25.7%, p<0.01), any cause of death; 18.1% vs. 9.5%, p=0.02, AMI; 7.4% vs. 2.4%, p=0.02, TVF; 38.3% vs. 19.2%, p<0.01).
Conclusion
Hemodialysis, multivessel disease and abundant calcium component may have accompanied with CN which may result in poor long-term prognosis.

Abstract
Abstract
Background
Recent reports show that stenting for coronary calcified nodule (CN) resulted in frequent in-stent restenosis, however, its predictors are unclear.
Method
117 consecutive calcified nodule lesions which underwent optical coherence tomography (OCT)-guided PCI were analyzed between January 2013 and March 2018. We investigated baseline characteristics and OCT parameter in CN site (Arc of CN, Lumen area and Symmetry index before and after PCI).
Result
CN site in-stent restenosis was seen 35 lesions (29.9%). Baseline characteristics was significantly different between restenosis group and non-restenosis group (Age; 68.9y.o vs. 73.3y.o, p=0.01, diabetes mellitus; 80.0% vs. 57.3%, Chronic Kidney Disease (CKD); 74.3% vs. 36.6%, Hemodialysis; 54.3% vs. 12.2%). Arc of CN before PCI in restenosis group was larger than that in non-restenosis group (122.7 vs. 110.0 degrees, p=0.01). Post stent symmetry index in restenosis group was smaller than that in non-restenosis group (0.64 vs. 0.75, p<0.01).
Conclusion
Younger patients, diabetes mellitus, CKD, hemodialysis, arc of CN before PCI, post stent symmetry index may be predictors of CN site restenosis.

Abstract
Sofosbuvir plus ledipasvir (SOF-LDV) combination therapy is a promising therapy for post-transplant hepatitis C virus (HCV) reinfection. It is known that gastric pH elevation induces lower absorption of ledipasvir; therefore, the use of proton pump inhibitors (PPIs) should be considered regarding dose reduction after SOF-LDV therapy induction. Here, we report two patients who developed duodenal ulcers due to the discontinuation of PPIs after the induction of SOF-LDV therapy for post-transplant HCV reinfection. The first patient was a 71-year-old man who had undergone living donor liver transplantation due to HCV-related liver cirrhosis. Lansoprazole, 30 mg daily, was discontinued upon SOF-LDV therapy induction. Seven days after SOF-LDV therapy induction, gastrointestinal endoscopy revealed the presence of a duodenal ulcer. The second patient was a 54-year-old man who had undergone living donor liver transplantation due to HCV-related end-stage liver disease. Similar to the first patient, rabeprazole sodium was discontinued upon the induction of SOF-LDV therapy. Eighteen days after SOF-LDV therapy induction, gastrointestinal endoscopy revealed the presence of a duodenal ulcer. In both cases, these duodenal ulcers improved after the resumption of the administration of PPIs, and a sustained virologic response at 12 weeks was achieved by SOF-LDV therapy with PPI use. Thus, PPI use should be continued consistently during SOF-LDV therapy for post-transplant HCV reinfection.

Abstract
Since its founding in 1993 the International Long-term Ecological Research Network (ILTER) has gone through pronounced development phases. The current network comprises 44 active member LTER networks representing 700 LTER Sites and ~80 LTSER Platforms across all continents, active in the fields of ecosystem, critical zone and socio-ecological research. The critical challenges and most important achievements of the initial phase have now become state-of-the-art in networking for excellent science. At the same time increasing integration, accelerating technology, networking of resources and a strong pull for more socially relevant scientific information have been modifying the mission and goals of ILTER. This article provides a critical review of ILTER's mission, goals, development and impacts. Major characteristics, tools, services, partnerships and selected examples of relative strengths relevant for advancing ILTER are presented. We elaborate on the tradeoffs between the needs of the scientific community and stakeholder expectations. The embedding of ILTER in an increasingly collaborative landscape of global environmental observation and ecological research networks and infrastructures is also reflected by developments of pioneering regional and national LTER networks such as SAEON in South Africa, CERN/CEOBEX in China, TERN in Australia or eLTER RI in Europe. The primary role of ILTER is currently seen as a mechanism to investigate ecosystem structure, function, and services in response to a wide range of environmental forcings using long-term, place-based research. We suggest four main fields of activities and advancements for the next decade through development/delivery of a: (1) Global multi-disciplinary community of researchers and research institutes; (2) Strategic global framework and strong partnerships in ecosystem observation and research; (3) Global Research Infrastructure (GRI); and (4) a scientific knowledge factory for societally relevant information on sustainable use of natural resources.

Abstract
Drug-induced pressure ulcer (DIPU), which is a newly recognized adverse drug reaction, is associated with the administration of psychiatric drugs in geriatric patients with dementia. The notification of the causative drugs is crucial to the treatment of DIPU. We herein report the case of a 56-year-old woman with early-stage Parkinson's disease who developed DIPUs after starting olanzapine treatment for depressive symptoms. Our findings illustrate that if an akinetic patient with pressure ulcers is encountered, the patient's medication should be reviewed by a multidisciplinary team, to evaluate whether the development of the pressure ulcer is drug-related, regardless of the patient's age.

Abstract
Land use and climate changes affect on the economy and environment with different patterns and magnitudes in the watershed. This study used risk analysis model stochastic efficiency with respect to a function (SERF) to evaluate economic and environmental risks caused by four climate change scenarios (baseline, small-, mid- and large changes) and three land uses (paddy dominated, paddy-farmland mixture and farmland dominated for agriculture) in Teshio watershed in northern Hokkaido, Japan. Under the baseline climate conditions, the lower ranking of economic income of crop yield and higher ranking of pollutant load from agricultural land were both predicted in paddy dominated for agriculture, suggesting that the paddy dominated system caused higher risks of economic and environmental variables compared to other two land uses. Increase of temperature and precipitation increased crop yields under all three climate changes which resulted in increase of the ranking of economic income, indicating that those climate changes could reduce economic risk. The increased temperature and precipitation also accelerated mineralization of organic nutrient and nutrient leaching to river course of Teshio which resulted in increase of the ranking of pollutant load, suggesting that those climate changes could lead to more environmental risk. The rankings of economic income in mid- and large changes of climate were lower than that in small change of climate under paddy-farmland mixture and farmland dominated systems due to decrease of crop yield, suggesting that climate change led to more economic risk. In summary, the results suggested that increase in temperature and precipitation caused higher risks of both economic and environmental perspectives, and the impacts was higher than those of land use changes in the studied watershed. Those findings would help producers and watershed managers to measure the tradeoffs between environmental protection and agricultural economic development for making decision under land use and climate changes.

Abstract
Hepatitis B virus (HBV) and hepatitis delta virus (HDV) co-infections progress rapidly and lead to cirrhosis. In Japan, the prevalence of HBV and HDV co-infected patients is low. Therefore, there are few reports of patients with HBV and HDV co-infection having undergone liver transplantation. Herein, we report a rare case of recurrence of HBV and HDV in a 41-year-old man who underwent living donor liver transplantation 4 years prior.

Abstract
Nitrogen (N) management presents a sustainability dilemma: N is strongly linked to energy and food production, but excess reactive N causes environmental pollution. The N footprint is an indicator that quantifies reactive N losses to the environment from consumption and production of food and the use of energy. The average per capita N footprint (calculated using the N-Calculator methodology) of ten countries varies from 15 to 47 kg N capita-1 year-1. The major cause of the difference is the protein consumption rates and food production N losses. The food sector dominates all countries' N footprints. Global connections via trade significantly affect the N footprint in countries that rely on imported foods and feeds. The authors present N footprint reduction strategies (e.g., improve N use efficiency, increase N recycling, reduce food waste, shift dietary choices) and identify knowledge gaps (e.g., the N footprint from nonfood goods and soil N process).

Abstract
INTRODUCTION Recently, several studies have shown that specific single nucleotide polymorphisms (SNPs) affect liver fibrosis progression in patients with hepatitis C virus (HCV) infection. In this study, we examined the impact of donor and recipient SNPs on the progression of fibrosis after liver transplantation for HCV infection. METHODS This cohort study enrolled 43 patients with HCV infection who underwent liver transplantation at our hospital. We evaluated 5 genotypes (rs4374383, rs2629751, rs9380516, rs8099917, and rs738409) that have been reported to be significant predictors of fibrosis in HCV infection using a Taqman assay. RESULTS Liver fibrosis (stage ≥ F1, New Inuyama classification) was detected at 1 year after liver transplantation in 30 cases (70%). The rs2629751 non-AA-genotype was found to be significantly associated with fibrosis progression at 1 year after liver transplantation (AA:GG or GA = 46%:88%, P < .05). The primary outcome was stage ≥F2 (portoportal septa) or liver-related mortality in 22 patients. The time to stage ≥F2 fibrosis or liver-related mortality was significantly different only in terms of the donor rs2629751 genotype (AA:GG or GA = 5.5 ± 0.6 years:3.6 ± 0.7 years, P = .025). CONCLUSIONS The rs2629751 genotype may be an important predictor of posttransplant outcome in HCV-infected patients. This result might be useful in donor selection for liver transplantation in HCV-infected patients and may guide therapeutic decisions regarding early antiviral treatment.

Abstract
BACKGROUND A penta-peptide, Gly-Pro-Ile-Gly-Ser (GPIGS), promotes proliferation of mouse hair keratinocytes and accelerates hair growth in mice. AIM OF THIS STUDY This study focused on the ability of the peptide to promote human hair growth. METHODS We used a human hair keratinocyte proliferation assay and organ cultures of human hair follicle as in vitro systems. The lotions with and without the penta-peptide were administered to 22 Japanese men with androgenetic alopecia (AGA) for 4 months in a double-blind and randomized clinical study. RESULTS The penta-peptide significantly stimulated the proliferation of human hair keratinocytes at a concentration of 2.3 μm (P < 0.01), and 5.0 μm of this peptide had a marked effect on hair shaft elongation in the organ culture (P < 0.05). The change in the proportion of thick hair (≥60 μm) compared to baseline in patients that received the peptide was significantly higher than in the placebo (P = 0.006). The change in the proportion of vellus hair (<40 μm) was also significantly lower in the peptide group than in the placebo (P = 0.029). The penta-peptide also significantly improved the appearance of baldness (P = 0.020) when blinded reviewers graded photographs of the participants according to a standardized baldness scale. No adverse dermatological effects due to treatment were noted during this clinical study. CONCLUSIONS This penta-peptide promotes proliferation of human hair keratinocytes and hair shaft elongation of human hair follicles, in vitro. This peptide increases thick hair ratio in vivo, and this compound is useful for the improvement of AGA.

Abstract
Diagnosis and treatment of bone metastasis requires various types of measures, specialists and caregivers. To provide better diagnosis and treatment, a multidisciplinary team approach is required. The members of this multidisciplinary team include doctors of primary cancers, radiologists, pathologists, orthopaedists, radiotherapists, clinical oncologists, palliative caregivers, rehabilitation doctors, dentists, nurses, pharmacists, physical therapists, occupational therapists, medical social workers, etc. Medical evidence was extracted from published articles describing meta-analyses or randomised controlled trials concerning patients with bone metastases mainly from 2003 to 2013, and a guideline was developed according to the Medical Information Network Distribution Service Handbook for Clinical Practice Guideline Development 2014. Multidisciplinary team meetings are helpful in diagnosis and treatment. Clinical benefits such as physical or psychological palliation obtained using the multidisciplinary team approaches are apparent. We established a guideline describing each specialty field, to improve understanding of the different fields among the specialists, who can further provide appropriate treatment, and to improve patients’ outcomes.

Abstract
Protease-resistant, misfolded isoforms (PrP(Sc)) of a normal cellular prion protein (PrP(C)) in the bodily fluids, including blood, urine, and saliva, are expected to be useful diagnostic markers of prion diseases, and nonhuman primate models are suited for performing valid diagnostic tests for human Creutzfeldt-Jakob disease (CJD). We developed an effective amplification method for PrP(Sc) derived from macaques infected with the atypical L-type bovine spongiform encephalopathy (L-BSE) prion by using mouse brain homogenate as a substrate in the presence of polyanions and L-arginine ethylester. This method was highly sensitive and detected PrP(Sc) in infected brain homogenate diluted up to 10(10) by sequential amplification. This method in combination with PrP(Sc) precipitation by sodium phosphotungstic acid is capable of amplifying very small amounts of PrP(Sc) contained in the cerebrospinal fluid (CSF), saliva, urine, and plasma of macaques that have been intracerebrally inoculated with the L-BSE prion. Furthermore, PrP(Sc) was detectable in the saliva or urine samples as well as CSF samples obtained at the preclinical phases of the disease. Thus, our novel method may be useful for furthering the understanding of bodily fluid leakage of PrP(Sc) in nonhuman primate models.
