Abstract
Patients with mild/moderate hemophilia (H)A, acquired HA (AHA) and lupus anticoagulants (LA), have prolonged aPTTs with low levels of factor (F)VIII activity, but the differentiation of these disorders is complex and time consuming. We established an approach to quickly differentiate these disorders using comprehensive coagulation tests. Patients' plasmas with mild/moderate HA, AHA, LA without anti-phospholipid syndrome [LA-APS(-)], and LA with APS [LA-APS(+)] were examined using clot waveform analysis (CWA) and thrombin generation test (TGT). Activated protein C (APC) sensitivity was assessed by TGT. CWA revealed similarly prolonged clot times in all groups [NP/mild/moderate HA/AHA/LA-APS(-)/LA-APS(+); 33 ± 1/82 ± 12/116 ± 44/90 ± 29/96 ± 15 s] but significantly different decreased maximal coagulation velocity (3.1 ± 0.1/1.3 ± 0.3/0.9 ± 0.5/1.6 ± 0.3/2.2 ± 0.5). In TGT, AHA group demonstrated severely reduced peak-thrombin levels (362 ± 23/170 ± 27/49 ± 21/158 ± 75/158 ± 99 nM), whilst both LA groups markedly prolonged lag times (4.5 ± 0.3/5.0 ± 0.4/4.7 ± 0.8/12.5 ± 7.7/28.8 ± 11.8 min), suggesting that AHA could be readily identified, but the different LA sub-types failed to be classified. An APC sensitivity demonstrated that 'normalized' APC-induced levels of peak thrombin in LA-APS(+) were significantly lower relative to LA-APS(-) (normalized %inhibition; 5 ± 7/42 ± 39 %). Our studies confirmed that %inhibition by APC was significantly decreased in NP preincubated with purified IgGs from LA-APS(+) compared to LA-APS(-), facilitating differentiation between LA groups. A combined approach using CWA and TGT could be a useful means of differentiating coagulation disorders with prolonged aPTT.

Abstract
A thin silicon sensor has been developed for active neutron personal dosemeters for use by aircrews and first responders. This thin silicon sensor is not affected by the funneling effect, which causes detection of cosmic protons and over-response to cosmic neutrons. There are several advantages to the thin silicon sensor: a decrease in sensitivity to gamma rays, an improvement of the energy detection limit for neutrons down to 0.8 MeV and an increase in the sensitivity to fast neutrons. Neutron response functions were experimentally obtained using 2.5 and 5 MeV monoenergy neutron beams and a (252)Cf neutron source. Simulation results using the Monte Carlo N-Particle transport code agree quite well with the experimental ones when an energy deposition region shaped like a circular truncated cone is used in place of a cylindrical region.

Abstract
AIM Sessile serrated adenomas/polyps (SSA/Ps) have been proposed as precursors of colorectal cancer. The aims of this investigation were to compare the endoscopic findings of SSA/Ps with those of other serrated lesions and to compare the histological findings of SSA/Ps with those of conventional adenomas. METHOD We retrospectively reviewed colonoscopy records at our institution from 1984 to 2013 and identified cases of endoscopically or surgically resected conventional adenomas and serrated lesions, including SSA/Ps, hyperplastic polyps (HPs) and traditional serrated adenomas (TSAs). The colonoscopic findings of SSA/Ps were compared with those of the other two serrated lesions and histological findings were compared among all groups of lesions. RESULTS There were 79 HPs in 68 patients, 77 SSA/Ps in 63 patients, 167 TSAs in 145 patients and 6324 conventional adenomas in 4129 patients. The inverted type and flat-elevated type were more frequent among SSA/Ps than among the other two types of serrated lesions. Magnifying colonoscopy revealed that a round and open pit pattern, expanded crypt openings and varicose microvascular vessels were more frequently observed among SSA/Ps than among the other types. The incidence of high-grade dysplasia or carcinoma among SSA/Ps (13.0%) was significantly higher than that among HPs (0%, P < 0.001) and equivalent to that among conventional adenomas (12.3%). CONCLUSION SSA/Ps have colonoscopic features distinct from those of HPs and TSAs. The malignant potential of SSA/Ps seems to be equal to that of conventional adenomas.

Abstract
To provide a macromolecular prodrug of 5-fluorouracil (5FU) with reduced side-effects, an affinity for tumor cells and exhibiting the high antitu mor activity, the covalent attachment of 5FU to chitosan and chitin through hexamethylene spacers via carbamoyl bonds was carried out. In vivo testing against p-388 lyphocytic leukemia in female CDF1 mice by intraperitoneal in jection ( i.p.) and the in vivo growth-inhibitory effect on Meth-A fibrosarcoma in SPF-C3H/He mice by subcutaneous injection (s.c.)/intravenous injection (i.v.) were evaluated. The effects of the degree of polymerization of chitosan and the degree of 5FU substitution per glucosamine unit on the prolongation of life were investigated. The chitosan-5FU and chitin-5FU conjugates exhibited high survival effects and chitosan-5FU conjugate showed significant growth- inhibitory effect on Meth-A fibrosarcoma. These chitosan-5FU and chitin-5FU conjugates did not display any acute toxicity in the 800 mg/kg dose range.

Abstract
AIM To evaluate the high-resolution computed tomography (CT) findings of primary lung cancer with cavitation and compare the findings in adenocarcinoma and squamous cell carcinoma. MATERIALS AND METHODS The high-resolution CT findings of tumours with cavitation were retrospectively evaluated in 60 patients. Forty-seven of the lesions were diagnosed as adenocarcinomas; 13 were diagnosed as squamous cell carcinomas. The diameters of the tumour and cavity, the maximum thickness of the cavity wall, shape of the cavity wall, the number of cavities, and the presence of ground-glass opacity, bronchial obstruction, intratumoural bronchiectasis, emphysema, and honeycombing were evaluated. The mechanisms of cavity formation were examined according to the pathological features. RESULTS The maximum thickness of the cavity wall was significantly greater in squamous cell carcinomas than in adenocarcinomas (p=0.002). Ground-glass opacity and intratumoural bronchiectasis were significantly more common in adenocarcinomas than in squamous cell carcinomas (p<0.001 and p=0.040, respectively). Regarding the pathological findings, intratumoural bronchiectasis with or without alveolar wall destruction contributed to a significant difference between adenocarcinoma and squamous cell carcinoma (p<0.001; odds ratio [OR], 20.35; 95% confidence interval [CI], 3.87-107.10). CONCLUSION The cavity wall tends to be thicker in squamous cell carcinomas than in adenocarcinomas. The presence of ground-glass opacity and intratumoural bronchiectasis is strongly suggestive of adenocarcinoma.

Abstract
This study was conducted to evaluate the attenuating potential of 2-hydroxypropyl-β-cyclodextrin (HPBCD) against Niemann-Pick Type C (NPC) disease, as well as the physical and chemical properties, particularly the cholesterol-solubilizing ability, in an NPC disease model in vitro. As parameters of NPC abnormalities, intracellular free and esterified cholesterol levels and lysosome volume were measured in Npc1 null Chinese hamster ovary cells. HPBCD showed dose-dependent effects against dysfunctional intracellular cholesterol trafficking, such as the accumulation and shortage of free and esterified cholesterols, respectively, in Npc1 null cells. However, the effectiveness was gradually offset by exposure to ≥8mM HPBCD. The same effect was also observed for increasing lysosome volume in Npc1 null cells. The degree of substitution of the hydroxypropyl group had little influence on the attenuating effects of HPBCD against the NPC abnormalities, at least in the range between 2.8 and 7.4. Next, we compared the effects of other hydroxyalkylated β-cyclodextrin derivatives with different cholesterol-solubilizing abilities, such as 2-hydroxyethyl-β-cyclodextrin (HEBCD) and 2-hydroxybutyl-β-cyclodextrin (HBBCD). The cholesterol solubilizing potential, attenuating effects against NPC abnormalities and cytotoxicity induction were HBBCD≫HPBCD>HEBCD, HBBCD=HPBCD>HEBCD and HBBCD≫HPBCD=HEBCD, respectively. HPBCD may be superior in terms of safety and efficacy in Npc1 null cells compared with HEBCD and HBBCD. The results of this study will provide a rationale for the optimization of HPBCD therapy for NPC disease.

Abstract
A compact toroid (CT) injector was developed for the C-2 device, primarily for refueling of field-reversed configurations. The CTs are formed by a magnetized coaxial plasma gun (MCPG), which consists of coaxial cylindrical electrodes and a bias coil for creating a magnetic field. First, a plasma ring is generated by a discharge between the electrodes and is accelerated by Lorenz self-force. Then, the plasma ring is captured by an interlinkage flux (poloidal flux). Finally, the fully formed CT is ejected from the MCPG. The MCPG described herein has two gas injection ports that are arranged tangentially on the outer electrode. A tungsten-coated inner electrode has a head which can be replaced with a longer one to extend the length of the acceleration region for the CT. The developed MCPG has achieved supersonic CT velocities of ∼100 km/s.

Abstract
OBJECTIVE Prevalence of ankle osteoarthritis (OA) is lower than that of knee OA, however, the molecular mechanisms underlying the difference remain unrevealed. In the present study, we developed mouse ankle OA models for use as tools to investigate pathophysiology of ankle OA and molecular characteristics of ankle cartilage. DESIGN We anatomically and histologically examined ankle and knee joints of C57BL/6 mice, and compared them with human samples. We examined joints of 8-week-old and 25-month-old mice. For experimental models, we developed three different ankle OA models: a medial model, a lateral model, and a bilateral model, by resection of respective structures. OA severity was evaluated 8 weeks after the surgery by safranin O staining, and cartilage degradation in the medial model was sequentially examined. RESULTS Anatomical and histological features of human and mouse ankle joints were comparable. Additionally, the mouse ankle joint was more resistant to cartilage degeneration with aging than the mouse knee joint. In the medial model, the tibiotalar joint was markedly affected while the subtalar joint was less degenerated. In the lateral model, the subtalar joint was mainly affected while the tibiotalar joint was less altered. In the bilateral model, both joints were markedly degenerated. In the time course of the medial model, TdT-mediated dUTP nick end labeling (TUNEL) staining and Adamts5 expression were enhanced at early and middle stages, while Mmp13 expression was gradually increased during the OA development. CONCLUSION Since human and mouse ankles are comparable, the present models will contribute to ankle OA pathophysiology and general cartilage research in future.

Abstract
A woman in her 50s visited our hospital in February 2015 with a complaint of dull abdominal pain in the right lower quadrant. She had a medical history of appendectomy for appendicitis in her 20s. Computed tomography(CT)revealed a tumor 90 mm in diameter near the ileocecum. Elective surgery was planned under the suspicion of gastrointestinal tumor, malignant lymphoma, or ileal cancer. She was emergently hospitalized 1 day earlier than scheduled because of high fever and severe abdominal pain. CT revealed that the tumor had increased to 120 mm in diameter without free air. Her white blood cell count was not elevated, and her symptoms improved readily with medical treatment. Thus, we performed the operation as scheduled. A tumor with a dark red recess on the surface had invaded the transverse colon intraoperatively, and a small amount of purulent ascites was present at the pouch of Douglas. We performed ileocecal resection with partial transverse colectomy. Histopathological examination led to the diagnosis of desmoid tumor in the mesentery of the terminal ileum. The surgical margins were negative for tumor cells. The tumor surface around the recess showed peritonitis, and the ascites showed no bacteria or tumor cells. The patient had been doing well without recurrence after discharge. Some cases of desmoid tumor with peritonitis have been reported, but most were caused by tumor penetration into the intestinal tract. We report herein a rare case of intra-abdominal desmoid tumor with abacterial peritonitis.

Abstract
609 Background: The purpose of this study was to characterize histological tumor regression grade (TRG) to colorectal liver metastases (CLM) treated with preoperative chemotherapy followed by liver surgery, and to evaluate whether TRG correlates with radiological response and prognosis. Methods: This study included 30 patients with CLM treated by surgical resection after preoperative chemotherapy with oxaliplatin- or irrinotecan-based regimens with or without molecular target agents. TRG was determined by the amount of fibrosis and necrosis replaced from tumor cells, ranging TRG 0 (0%), 1 (1-24%), 2 (25-50%), 3 (51-99%), and 4 (100%). Results: TRG 0, 1, 2, 3, and 4 were observed in 0%, 6.7%, 10.0%, 66.7%, and 16.6% of the patients, respectively. There were no relations between TRG and regimen, including molecular target agents. As shown in the table, radiological response was not significantly correlated with TRG. Patients with histological major response (TRG 3+4) had better prognosis (MST; TRG 1+2 vs. 3+4: 20.0 vs. 50 months, P= 0.007), and a multivariate analysis identified histological major response as an independent good prognostic factor. Conclusions: In this analysis, histological TRG predicted survival after preoperative chemotherapy and resection for CLM. Preoperative radiological response could not evaluate TRG. [Table: see text]

Abstract
AIM Diabetes mellitus increases the risk of cardiovascular disease, which is accompanied by functional and structural changes in the vascular system. Microparticles (MPs) have been described as biological vectors of endothelial dysfunction in other pathologies. However, the molecular mechanisms underlying their formation and signalling are unclear. We investigated the role of MPs derived from streptozotocin (STZ)-induced diabetic rats in endothelial function. METHODS Male Wistar rats were injected with STZ to induce diabetes, and MPs isolated from control or STZ-induced diabetic rats were characterized by dot blotting (assessed by CD62P detections), flow cytometry (assessed by annexin V detections) and ELISA. Carotid arteries from rats were incubated with MPs, and expressions of enzymes and endothelium-dependent relaxation were analysed. RESULTS The circulating levels of MPs, particularly the levels of platelet-derived microparticles, from diabetic rats were higher than those present in controls. Endothelium-dependent relaxation induced by acetylcholine (ACh) was attenuated in carotid arteries from STZ-induced diabetic rats. Following the incubation of control carotid arteries with MPs isolated from STZ rats, ACh-induced endothelium-dependent relaxation was impaired, but MPs isolated from control rats had no such effect. Furthermore, the effect of MPs was mediated by a decrease in expression of endothelial nitric oxide synthase (eNOS) and the overexpression of caveolin-1. CONCLUSION Circulating MPs isolated from STZ-induced diabetic rats induce endothelial dysfunction in carotid arteries and regulate protein expressions of eNOS and caveolin-1. These data advance our understanding of the deleterious effects of circulating MPs observed in disorders with diabetic complications.

Abstract
The potential use of induced pluripotent stem cells (iPSCs) in personalized regenerative medicine applications may be augmented by transgenics, including the expression of constitutive cell labels, differentiation reporters, or modulators of disease phenotypes. Thus, there is precedence for reproducible transgene expression amongst iPSC sub-clones with isogenic or diverse genetic backgrounds. Using virus or transposon vectors, transgene integration sites and copy numbers are difficult to control, and nearly impossible to reproduce across multiple cell lines. Moreover, randomly integrated transgenes are often subject to pleiotropic position effects as a consequence of epigenetic changes inherent in differentiation, undermining applications in iPSCs. To address this, we have adapted popular TALEN and CRISPR/Cas9 nuclease technologies in order to introduce transgenes into pre-defined loci and overcome random position effects. AAVS1 is an exemplary locus within the PPP1R12C gene that permits robust expression of CAG promoter-driven transgenes. Gene targeting controls transgene copy number such that reporter expression patterns are reproducible and scalable by ∼2-fold. Furthermore, gene expression is maintained during long-term human iPSC culture and in vitro differentiation along multiple lineages. Here, we outline our AAVS1 targeting protocol using standardized donor vectors and construction methods, as well as provide practical considerations for iPSC culture, drug selection, and genotyping.

Abstract
BACKGROUND Maintaining the genetic integrity in long-term tissue cultured and cryopreserved plants is important for the conservation of plant genetic resources. OBJECTIVE In this study, the genetic stability of cryopreserved wasabi shoot tips stored for 10 years at -150 degree C was visualized using Amplified Fragment Length Polymorphism (AFLP) and Methylation Sensitive Amplified Polymorphism (MSAP). MATERIALS AND METHODS The study included plants derived from cryopreserved shoot tips after 10.5 years storage at -150 degree C (LN10yr), after 2 h storage at -196 degree C (LN2hr), cryopreservation controls (No LN cooling (TC)) and non-treated controls without LN cooling (LC). The donor plants for LN2hr, TC and LC were also maintained in vitro at 20 degree C for the same period. RESULTS Neither technique detected genetic variations in either control or cryopreserved plants. Some mutations were noted in plants maintained in tissue culture for 10 years. Comparison of genome stability for TC and LN2hr plants showed only a minor change in DNA. However, when comparing the LC and Ln10yr, many differences were found. CONCLUSION We conclude that cryopreservation is a superior conservation method compared to tissue culture in maintaining genetic stability for a long-term storage of wasabi germplasm.

Abstract
A 60-year-old Japanese man presented to our hospital for further investigation of an elevated serum anti-p53 antibody level. He was diagnosed with colon cancer and the tumour was surgically resected. Histological diagnosis of advanced colon cancer without lymph node involvement or distant metastasis was made. It was noteworthy that both serum carcinoembryonic antigen (CEA) and a fecal occult blood test that were performed preoperatively were non-diagnostic. This case highlights the potential usefulness of serum anti-p53 antibody tests for detection of colorectal cancers. Moreover, sequential changes in the anti-p53 antibody levels after curative resection were observed.

Abstract
Recently a parvovirus called bufavirus (BuV) has been implicated as a causative agent of diarrhoea. To further reveal the epidemiology and genetic characteristics of BuV, this study was performed in Turkish children with diarrhoea. BuV was detected in 1.4% (8/583) of stool samples. All stool samples from healthy children (n = 148) were negative for BuV. Diarrhoea in BuV-positive patients was severe and occurred mainly during the colder months of the year. Complete genome sequences were generated from four BuVs. Only BuV3 was found, which was genetically and phylogenetically similar to Bhutanese BuV3, indicating that BuV3 is prevalent in Asian countries.

Abstract
The formation process of Pt decorated Ni-Pt nanocubes was investigated by analysing the elemental distribution of Ni and Pt in the particles obtained from time-resolved in situ sampling during the synthesis in the oleylamine-1-heptanol system. The analysis confirmed the formation of Pt(core)-Ni(shell) nanoparticles at the initial stages of the reaction. However, as the reaction time progressed, the Pt atoms at the centre diffused outward and reached the corners and edges of the particle, whose shape changed from nearly spherical at the initial stages of the reaction to a perfect cube at the end of the reaction, forming a Ni rich cube (core)-Pt(cage). The cage obtained by dissolving the Ni rich cube was composed mainly of Pt and the Ni content in the frame was a mere 12%. The catalytic activity of the Pt cage was measured using cyclic voltammetry. The initial measurements suggested that the activity was comparable to some of the commercially available Pt catalysts.

Abstract
In this study, we focused on the anti-inflammatory effect of cordycepin, 3′-deoxyadenosine. Cordycepin potently suppressed nitric oxide production in lipopolysaccharide-stimulated RAW 264.7 cells in an adenosine receptor-independent manner. In addition, inhibitors for adenosine kinase and nucleoside transporter abrogated the action of cordycepin. Thus, we considered that intracellular metabolism cordycepin is important for the anti-inflammatory effect of cordycepin.

Abstract
The number of reported cases of alpha-fetoprotein (AFP)-producing gastric cancer has gradually increased, with a reported prevalence of 1.3–1.5% of all gastric cancer cases. However, reports of gastric cancer accompanied by elevated serum levels of both AFP and protein induced by vitamin K antagonist-II (PIVKA-II) are rare. The prognosis of AFP- and PIVKA-II-producing gastric cancer has been reported to be very poor because the tumor cells were considered to have a high malignant potential and the cancer progressed rapidly. We described a case of gastric cancer producing AFP and PIVKA-II in which chemotherapy was effective and resulted in prolonged survival, and these two tumor markers were useful for monitoring the treatment response. Routine health screening using upper abdominal ultrasonography revealed hepatic tumors in an apparently healthy 65-year-old man. Whole-body computed tomography (CT) revealed multiple hepatic tumors, and an esophagogastroduodenoscopy (EGD) revealed a Bormann type 3 tumor in the lower stomach. A biopsy specimen confirmed that the tumor was immunohistochemically positive for AFP, PIVKA-II, and human epidermal growth factor receptor 2. After chemotherapy, the gastric tumor appeared as a small elevated lesion on EGD, and CT revealed a remarkable reduction in the size of the metastatic liver tumors. The patient is still alive, 35 months after the initial chemotherapy.

Abstract
The clinical and immunological studies of an unusual case of chronic mucocutaneous candidiasis (CMCC) are reported. An 18-year-old male with life-long CMCC was superinfected by a dermatophyte showing exophytic clinical features in his childhood. In addition he has suffered from fatal cryptococcal meningitis since the age of 18. The combination of three fungi, i.e., Candida albicans, Trichophyton mentagrophytes and Cryptococcus neoformans, has not been found in an examination of the literature. The author's hypothesis, "immune deviation theory" in the pathogenesis of CMCC, is presented in detail. The possible role of hypovitaminosis A anddisorder of iron metabolism in CMCC and treatment of CMCC are reviewed briefly.

Abstract
BACKGROUND Postoperative opioid analgesia increases the incidence of postoperative nausea and vomiting (PONV). We investigated whether a combination of the neurokinin-1 antagonist aprepitant and dexamethasone decreases PONV incidence compared with dexamethasone alone in high-risk patients receiving continuous epidural fentanyl. METHODS Sixty nonsmoking female patients scheduled for elective knee osteoarthritis surgery were randomly allocated to receive oral aprepitant 80 mg (aprepitant+dexamethasone group, N.=30) 2 h before anesthesia induction or no oral aprepitant (dexamethasone group, N.=30). All patients received intravenous dexamethasone 8 mg immediately before anesthesia induction. Anesthesia was maintained with remifentanil and sevoflurane. Continuous infusion of epidural analgesia, including fentanyl, was provided during and after surgery. We assessed complete response (no PONV and no rescue antiemetic use), incidence of nausea and vomiting, nausea severity scale, vomiting frequency, rescue antiemetic use, and postoperative pain at 2 and 24 h after surgery. RESULTS The cumulative incidence of vomiting at 24 h was 3% in the aprepitant+dexamethasone group and 27% in the dexamethasone group (P=0.011). The incidence and frequency of vomiting in the late postoperative period was also significantly lower in the aprepitant+dexamethasone group than in the dexamethasone group. However, there were no significant group differences in the proportion of patients who experienced a complete response, the incidence and severity of nausea, and rescue antiemetic use at 24 h. CONCLUSION The combination of aprepitant and dexamethasone was more effective in preventing postoperative vomiting compared with dexamethasone alone in patients at high-risk of PONV from continuous epidural fentanyl analgesia.

Abstract
This study examined the effects of regular post-exercise cold application on muscular and vascular adaptations induced by moderate-intensity resistance training. 14 male subjects participated in resistance training: 5 sets of 8 wrist-flexion exercises at workload of 70-80% of the single repetition maximum, 3 times a week for 6 weeks. 7 subjects immersed their experimental forearms in cold water (10±1°C) for 20 min after wrist-flexion exercises (cooled group), and the other 7 served as control subjects (noncooled group). Measurements were taken before and after the training period; wrist-flexor thickness, brachial-artery diameter, maximal muscle strength, and local muscle endurance were measured in upper extremities. Wrist-flexor thicknesses of the experimental arms increased after training in both groups, but the extent of each increase was significantly less in the cooled group compared with the noncooled group. Maximal muscle strength and brachial-artery diameter did not increase in the cooled group, while they increased in the noncooled group. Local muscle endurance increased in both groups, but the increase in the cooled group tended to be lower compared to the noncooled group. Regular post-exercise cold application to muscles might attenuate muscular and vascular adaptations to resistance training.

Abstract
The quasiskutterudite superconductor Sr_{3}Rh_{4}Sn_{13} features a pronounced anomaly in electrical resistivity at T^{*}∼138 K. We show that the anomaly is caused by a second-order structural transition, which can be tuned to 0 K by applying physical pressure and chemical pressure via the substitution of Ca for Sr. A broad superconducting dome is centered around the structural quantum critical point. Detailed analysis of the tuning parameter dependence of T^{*} as well as insights from lattice dynamics calculations strongly support the existence of a structural quantum critical point at ambient pressure when the fraction of Ca is 0.9 (i.e., x_{c}=0.9). This establishes the (Ca_{x}Sr_{1-x})_{3}Rh_{4}Sn_{13} series as an important system for exploring the physics of structural quantum criticality without the need of applying high pressures.

Abstract
The aim of the study was to examine the relationship between the brain natriuretic peptide (BNP) level and progression or remission of diabetic nephropathy with microalbuminuria for 3 years. The subjects were 100 Japanese type 2 diabetes mellitus outpatients with microalbuminuria. Associations between metabolic parameters at baseline [HbA1c, systolic blood pressure (SBP), urine albumin-creatinine ratio (ACR), estimated glomerular filtration rate (eGFR), and BNP] and the progression or remission of diabetic nephropathy were examined for 3 years. A total of 83 patients were examined at the end of the 3-year period, including 17 with remission to normoalbuminuria, 47 with continuing microalbuminuria, and 19 with progression to macroalbuminuria. HbA1c, ACR, and BNP differed significantly among the 3 groups (p=0.024, p<0.001, p=0.002, respectively). Among baseline factors, HbA1c and BNP were significant predictors of the percentage increase in ACR for 3 years in multiple linear regression analysis (β=0.259, p=0.02; β=0.299, p=0.007, respectively). In multivariate logistic regression analysis, HbA1c and ACR were independently associated with progression of diabetic nephropathy (p=0.008, p=0.023, respectively), and ACR and BNP were independently associated with remission of diabetic nephropathy (p=0.029, p=0.012, respectively). ROC curve analysis gave a cutoff value for BNP of 14.9 pg/ml for prediction of remission of diabetic nephropathy (p=0.016). The BNP level has a relationship with diabetic nephropathy and a low BNP level predicts remission of diabetic nephropathy. Therefore, monitoring of BNP can play an important role in management of diabetic nephropathy.

Abstract
SUMMARY A 12-month extension phase of DIRECT in Japanese subjects with osteoporosis showed that total 3 years of denosumab treatment in Japanese postmenopausal women and men with osteoporosis was associated with low fracture rates, persistent bone turnover marker (BTM) reductions, continuous bone mineral density (BMD) increases, and a favorable overall benefit/risk profile. INTRODUCTION The DIRECT trial demonstrated that 2 years of treatment with denosumab 60 mg subcutaneously every 6 months significantly reduced the incidence of vertebral fracture compared to placebo in Japanese postmenopausal women and men with osteoporosis. The purpose of this study is to evaluate the efficacy and safety of denosumab treatment for up to 3 years. METHODS This study includes a 2-year randomized, double-blind, placebo-controlled phase and a 1-year open-label extension phase in which all subjects received denosumab. The data correspond to 3 years of denosumab treatment in subjects who received denosumab (long-term group) and 1 year of denosumab treatment in subjects who received placebo (cross-over group) in the double-blind phase. RESULTS Eight hundred and ten subjects who completed the double-blind phase enrolled into the extension phase, and 775 subjects completed the study. All subjects received denosumab with daily supplements of calcium and vitamin D. The cumulative 36-month incidences of new or worsening vertebral fractures and new vertebral fractures were 3.8 and 2.5 %, respectively, in the long-term group. In this group, the BMD continued to increase, and the reduction in BTMs was maintained. In the cross-over group, comparable BMD increases and BTMs reductions to those of in their first year of the long-term group were confirmed. Adverse events did not show a notable increase with long-term denosumab administration. One event of osteonecrosis of the jaw occurred in the cross-over group. CONCLUSIONS Three-year denosumab treatment in Japanese subjects with osteoporosis showed a favorable benefit/risk profile.
