1Interventional treatment for unresectable hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC) is the sixth most common cancer and third leading cause of cancer-related death in the world. The Barcelona clinic liver cancer classification is the current standard classification system for the clinical management of patients with HCC and suggests that patients with intermediate-stage HCC benefit from transcatheter arterial chemoembolization(TACE). Interventional treatments such as TACE, balloon-occluded TACE, drug-eluting bead embolization, radioembolization, and combined therapies including TACE and radiofrequency ablation, continue to evolve, resulting in improved patient prognosis. However, patients with advanced-stage HCC typically receive only chemotherapy with sorafenib, a multi-kinase inhibitor, or palliative and conservative therapy. Most patients receive palliative or conservative therapy only, and approximately 50% of patients with HCC are candidatesfor systemic therapy. However, these patients require therapy that is more effective than sorafenib or conservative treatment. Several researchers try to perform more effective therapies, such as combined therapies(TACE with radiotherapy and sorafenib with TACE), modified TACE for HCC with arterioportal or arteriohepatic vein shunts, TACE based on hepatic hemodynamics, and isolated hepatic perfusion. This review summarizes the published data and data on important ongoing studies concerning interventional treatments for unresectable HCC and discusses the technical improvements in these interventions, particularly for advanced-stage HCC.Satoru Murata Takahiko Mine Fumie Sugihara Daisuke Yasui Hidenori Yamaguchi Tatsuo Ueda Shiro Onozawa Shin-ichiro Kumita 2014World Journal of Gastroenterology2014,20,37:38
2Toll-like receptor 4 as a possible therapeutic target for delayed brain injuries after aneurysmal subarachnoid hemorrhage显示文摘Neuroinflammation is a well-recognized consequence of subarachnoid hemorrhage(SAH), and Toll-like receptor(TLR) 4 may be an important therapeutic target for post-SAH neuroinflammation. Of the TLR family members, TLR4 is expressed in various cell types in the central nervous system, and is unique in that it can signal through both the myeloid differentiation primary-response protein 88-dependent and the toll receptor associated activator of interferon-dependent cascades to coordinate the maximal inflammatory response. TLR4 can be activated by many endogenous ligands having damage-associated molecular patterns including heme and fibrinogen at the rupture of an intracranial aneurysm, and the resultant inflammatory reaction and thereby tissue damages may furthermore activate TLR4. It is widely accepted that the excreted products of TLR4 signaling alter neuronal functions. Previous studies have focused on the pathway through nuclear factor(NF)-κΒ signaling among TLR4 signaling pathways as to the development of early brain injury(EBI) such as neuronal apoptosis and blood-brain barrier disruption, and cerebral vasospasm. However, many findings suggest that both pathways via NF-κΒ and mitogen-activated protein kinases may be involved in EBI and cerebral vasospasm development. To overcome EBI and cerebral vasospasm is important to improve outcomes after SAH, because both EBI and vasopasm are responsible for delayed brain injuries or delayed cerebral ischemia, the most important preventable cause of poor outcomes after SAH. Increasing evidence has shown that TLR4 signaling plays an important role in SAH-induced brain injuries. Better understanding of the roles of TLR4 signaling in SAH will facilitate development of new treatments.Takeshi Okada Hidenori Suzuki 2017Neural Regeneration Research2017,12,2:22
3Matricellular proteins as possible biomarkers for early brain injury after aneurysmal subarachnoid hemorrhage显示文摘Aneurysmal subarachnoid hemorrhage remains devastating,and the most important determinant of poor outcome is early brain injury(EBI).In clinical settings,as a surrogate marker of EBI,loss of consciousness at ictus,poor initial clinical grades,and some radiographic findings are used,but these markers are somewhat subjective.Thus,it is imperative to find biomarkers of EBI that have beneficial prognostic and therapeutic implications.In our opinion,an ideal biomarker is a molecule that is implicated in the pathogenesis of both EBI and subsequently developing delayed cerebral ischemia(DCI),being a therapeutic target,and can be measured easily in the peripheral blood in an acute stage.A good candidate of such a biomarker is a matricellular protein,which is a secreted,inducible and multifunctional extracellular matrix protein.There are many kinds of matricellular proteins reported,but only tenascin-C,osteopontin,galectin-3 and periostin are reported relevant to EBI and DCI.Reliable biomarkers of EBI may stratify aneurysmal subarachnoid hemorrhage patients into categories of risk to develop DCI,and allow objective monitoring of the response to treatment for EBI and earlier diagnosis of DCI.This review emphasizes that further investigation of matricellular proteins as an avenue for biomarker discovery is warranted.Hidenori Suzuki Hirofumi Nishikawa Fumihiro Kawakita 2018Neural Regeneration Research2018,13,7:20
4氢气爆炸特性研究(英文)显示文摘本文研究、总结了氢气与空气(氢气与氧气)的混合物的爆炸特性。即氢气在空气中,在比较低燃烧界限的情况下,只有向上的传播和非常少的超压可以观测得到。正因为氢气的这种特性,将氢应用于科技将极大地推进社会进步,氢燃料将成为一种主要的能源。然而,氢技术应用的成功与否主要取决于氢使用的安全性。所以,必须掌握实际使用时氢气燃烧的性能。本文在日本过去十年实验数据的基础上,通过实验研究了氢气与空气混合物的燃点。研究了氢气、氧气混合物经氮气稀释后,按化学当量比例将不同浓度的氢气与空气进行混合,并得出了低温下的爆炸压力特性。随后,分别讨论了在初始压力下一致的情况下,试管直径相同的状况下,氢气与空气混合浓度相同的情况下,这三种爆轰传播限制之间的关系。得出了在空气中直接点燃的发生爆轰的最小试管直径,最小的装药量之间的关系,进行了爆轰危险性分级。最后,文章概括比较了氢与其他燃料的燃烧特性,评估了氢气燃烧过程中的危险与安全因素。Hidenori Matsui 2005中国安全生产科学技术2005,1,6:17
5Potential therapeutic molecular targets for blood-brain barrier disruption after subarachnoid hemorrhage显示文摘Aneurysmal subarachnoid hemorrhage remains serious hemorrhagic stroke with high morbidities and mortalities.Aneurysm rupture causes arterial bleeding-induced mechanical brain tissue injuries and elevated intracranial pressure,followed by global cerebral ischemia.Post-subarachnoid hemorrhage ischemia,tissue injuries as well as extravasated blood components and the breakdown products activate microglia,astrocytes and Toll-like receptor 4,and disrupt blood-brain barrier associated with the induction of many inflammatory and other cascades.Once blood-brain barrier is disrupted,brain tissues are directly exposed to harmful blood contents and immune cells,which aggravate brain injuries furthermore.Blood-brain barrier disruption after subarachnoid hemorrhage may be developed by a variety of mechanisms including endothelial cell apoptosis and disruption of tight junction proteins.Many molecules and pathways have been reported to disrupt the blood-brain barrier after subarachnoid hemorrhage,but the exact mechanisms remain unclear.Multiple independent and/or interconnected signaling pathways may be involved in blood-brain barrier disruption after subarachnoid hemorrhage.This review provides recent understandings of the mechanisms and the potential therapeutic targets of blood-brain barrier disruption after subarachnoid hemorrhage.Hideki Kanamaru Hidenori Suzuki 2019Neural Regeneration Research2019,14,7:15
6Hepatic schwannoma:Imaging findings on CT,MRI and contrast-enhanced ultrasonography显示文摘A primary benign schwannoma of the liver is extremely rare and is difficult to preoperatively discriminate from a malignant tumor.We compared the imaging and pathological findings,and examined the possibility of preoperatively diagnosing a benign liver schwannoma.A 72-year-old woman was admitted to our hospital because of a 4.6-cm mass in the liver.A malignant tumor was suspected,and a right hepatectomy was performed.After this,the diagnosis of a primary benign schwannoma of the liver was made through pathological examination.Contrast-enhanced ultrasonography(CEUS) with Sonazoid showed minute blood flows into the septum and solid areas of the tumor in the vascular phase;most likely due to increased arterial flow associated with infiltration of chronic inflammatory cells.In the postvascular phase,CEUS showed contrast defect of cystic areas and delayed enhancement of solid areas;most likely due to aggregation of siderophores.Because discriminating between a benign and malignant schwannoma of the liver is difficult,surgery is generally recommended.However,the two key findings from CEUS may be useful in discriminating ancient schwannoma by recognizing the hemorrhage involved in the secondary degeneration and aggregation of siderophores.Yu Ota Kazunobu Aso Kenji Watanabe Takahiro Einama Koji Imai Hidenori Karasaki Ryuji Sudo Yosui Tamaki Mituyoshi Okada Yosihiko Tokusashi Toru Kono Naoyuki Miyokawa Masakazu Haneda Masahiko Taniguchi Hiroyuki Furukawa 2012World Journal of Gastroenterology2012,18,35:11
7超声波辅助农杆菌介导CP基因转化番小瓜(Carioca papaya L.)的有效方法显示文摘本研究探索了通过农杆菌介导,超声波辅助处理,转化番木瓜胚性愈伤组织,获得转基因植株的有效方法。分别将含有日本PLDMV 外壳蛋白基因(PTi-Epj-TL-PLDMV)和含有台湾PRSV 菌株、美国夏威夷PRSV 菌株、泰国PRSV 菌株及日本PLDMV 菌株的多元外壳蛋白基因编码序列(PTi-NP-YKT)插入双元载体质粒pGA482G,借助于农杆菌系LBA4404将双元载体上的外壳蛋白基因和新霉素磷酸转移酶基因(nptⅡ)转移到番木瓜品种Sunset 的胚性愈伤组织中,从而获得抗卡那霉素的转化再生植株。试验着重在转化方法上进行探索。结果表明,农杆菌过夜培养后,用高渗透压培养液(1/2 MS+6%蔗糖+1%葡萄糖,pH 5.7)调整至光密度OD_(600(?)m)=0.15-0.20,然后用该菌液感染材料30min,其间辅以超声波处理,可以大大提高转化效率。用15ml 无菌离心管装载胚性愈伤材料进行15s 的超声波处理,在80块被转化的胚性愈伤中获得21个CP 基因G 转化系(26.3%),而在对照处理64块胚性愈伤中仅获得1个转化系(1.6%);在经过15s 的超声波处理48块被转化的胚性愈伤中获得8个CP 基因B 转化系(16.7%),而在对照处理25块胚性愈伤中未出现转化系。上述操作方法用在两种CP 基因转化上均表现出相似的效果。试验还表明:120mg/L 是卡那霉素抗性筛选的最佳浓度。抗性筛选9个月后,在421块胚性愈伤组织中产生了42个抗卡那霉素的转化系。所获得的转基因植株分别用PCR 和Southern 印迹杂交进行了鉴定。姜玲 MAOKA Tetsuo KOMORI Sadao FUKAMACHI Hiroshi KATO Hidenori OGAWA Kazunori 2004实验生物学报2004,37,3:11
8Aluminum potassium sulfate and tannic acid sclerotherapy for Goligher Grades Ⅱ and Ⅲ hemorrhoids: Results from a multicenter study显示文摘AIM: To show that aluminum potassium sulfate and tannic acid(ALTA) sclerotherapy has a high success rate for Grade Ⅱ and Ⅲ hemorrhoids.METHODS: This study was based on the clinical data of 604 patients with hemorrhoids who underwent ALTA sclerotherapy between January 2009 and February 2015. The objective of this study was to assess the efficacy of this treatment for Grades Ⅱ and Ⅲ hemorrhoids. Preoperative and postoperative symptoms, complications and success rate were all assessed retrospectively. Follow-up consisted of a simple questionnaire, physical examination and an anoscopy. Patients were followed-up at one day, one week, two weeks, one month, one year, two years, three years, four years and five years after the ALTA sclerotherapy.RESULTS: One hundred and sixty-nine patients were diagnosed with Grade Ⅱ hemorrhoids and 435 patients were diagnosed with Grade Ⅲ hemorrhoids. The one year, three year and five year cumulative success rates of ALTA sclerotherapy for Grades Ⅱ and Ⅲ hemo-rrhoids were 95.9% and 93.1%; 89.3% and 83.7%; and 89.3% and 78.2%, respectively. No significant differences were observed in the cumulative success rates after ALTA sclerotherapy between Grades Ⅱ and Ⅲ hemorrhoids(P = 0.09). There were forty-seven post-operative complications(low grade fever; anal pain; urinary retention; rectal ulcer; and others). No serious or life-threatening complications occurred and all cases improved through conservative treatment. At univariate analysis there were no predictive factors of failure.CONCLUSION: ALTA sclerotherapy has had a high success rate for Grade Ⅱ and Ⅲ hemorrhoids during five years of post-operative treatment. However, additional studies are needed to evaluate the efficacy of this ALTA sclerotherapy in the management of hemorrhoidal disease.Hidenori Miyamoto Takenori Hada Gentaro Ishiyama Yoshito Ono Hideo Watanabe 2016World Journal of Hepatology2016,8,20:10
9Cyclooxygenase-2 expression after preoperative chemoradiotherapy correlates with more frequent esophageal cancer recurrence显示文摘AIM: To investigate the relationship between cycloo- xygenase-2 (COX-2), and vascular endothelial growth factor (VEGF), and to determine the clinical significance of this relationship in esophageal cancer patients undergoing chemoradiotherapy (CRT). METHODS: Immunohistochemical staining was used to evaluate COX-2 and VEGF expression in 40 patients with histologically-confirmed esophageal squamous carcinoma (ESCC) who were undergoing preoperative CRT. RESULTS: Fourteen out of 40 ESCC patients showed a pathological complete response (CR) after CRT. COX-2 and VEGF protein expressions were observed in the cytoplasm of 17 and 13 tumors, respectively, with null expression in 9 and 13 tumors, respectively. COX-2 expression was strongly correlated with VEGF expression (P < 0.05). There were also significant associations between COX-2 expression, tumor recurrence, and lymph-node involvement (P = 0.0277 and P = 0.0095, respectively). COX-2 expression and VEGF expression had significant prognostic value for disease-free survival (log-rank test; P = 0.0073 and P = 0.0341, respectively), but not for overall survival, as assessed by univariate analysis. CONCLUSION: Our results suggest that COX-2 expression correlates with VEGF expression and might be a useful prognostic factor for more frequent tumor recurrence in ESCC patients undergoing neoadjuvant CRT. These findings support the use of anti-angiogenic COX-2 inhibitors in the treatment of ESCC.Reigetsu Yoshikawa Yoshinori Fujiwara Kenji Koishi Syoudou Kojima Tomohiro Matsumoto Hidenori Yanagi Takehira Yamamura Tomoko Hashimoto-Tamaoki Takashi Nishigami Tohru Tsujimura 2007World Journal of Gastroenterology2007,13,16:9
10Persistent CXCR4 expression after preoperative chemoradiotherapy predicts early recurrence and poor prognosis in esophageal cancer显示文摘AIM: To study the effect of CXC chemokine receptor-4 (CXCR4) expression on disease progression and prognosis in esophageal cancer. METHODS: CXCR4 expression was evaluated in 37 patients with histologically confirmed esophageal squamous carcinomas (ESCC) undergoing preoperative chemoradiotherapy (CRT) by immunohistochemical staining. RESULTS: Eleven out of 37 ESCC patients showed a pathological complete response (CR) after CRT. CXCR4 protein expression was observed in cell cytoplasms of 13 tumors, and null expression was seen in 13 tumors. Distant recurrence was significantly more common in patients with positive CXCR4 expression (P = 0.0318). After a median follow-up time of 31.6 mo, 19 patients progressed (12 of 19 expressed positive CXCR4) and 11 died (10 of 11 expressed positive CXCR4). Overall survival was significantly correlated with lymph node metastasis (952.1 ± 53.8 d in negative group vs 475.1 ± 56.2 d in positive group, P = 0.023), distant metastasis (874.0 ± 60.4 d in negative group vs 434.9 ± 75.2 d in positive group, P = 0.014) and CRT (811.5 ± 51.2 d in responder group vs 459.6 ± 94.0 d in non-responder group, P = 0.00038) and further with an absence ofCXCR4 expression or no residual tumor (959.8 ± 51.0 d in null expression or no tumor group vs 412.0 ± 57.1 d in positive expression group, P = 0.0001). CONCLUSION: Persistent positive CXCR4 expression is implicated in tumor aggressiveness and poor prognosis in ESCC after CRT, and preoperative CRT may improve the prognosis of ESCC via CXCL12-CXCR4 signaling pathway.Kenji Koishi Reigetsu Yoshikawa Tohru Tsujimura Tomoko Hashimoto-Tamaoki Syoudou Kojima Hidenori Yanagi Takehira Yamamura Yoshinori Fujiwara 2006World Journal of Gastroenterology2006,12,47:9
11Implications of periostin in the development of subarachnoid hemorrhage-induced brain injuries显示文摘Target of research in subarachnoid hemorrhage(SAH):The outcome of aneurysmal SAH remains poor despite advances in the diagnosis and treatment.Although many factors related to patients,aneurysms,and institutions,as well as physiological parameters and medical complications were reported as prognostic factors,the most important determinant of poorHirofumi Nishikawa Hidenori Suzuki 2017Neural Regeneration Research2017,12,12:9
12Evaluation of the relationship between hepatocellular carcinoma location and transarterial chemoembolization efficacy显示文摘AIM To evaluate the relationship between the location of hepatocellular carcinoma(HCC) and the efficacy of transarterial chemoembolization(TACE).METHODS We evaluated 115 patients(127 nodules), excluding recurrent nodules, treated with TACE between January 2011 and June 2014. TACE efficacy was evaluated according to m RECIST. The HCC location coefficient was calculated as the distance from the central portal portion to the HCC center(mm)/liver diameter(mm) on multiplanar reconstruction images rendered(MPR) to visualize bifurcation of the right and left branches of the portal vein and HCC center. The HCC location coefficient was compared between complete response(CR) and non-CR groups in Child-Pugh grade A and B patients.RESULTS The median location coefficient of HCC among all nodules, the right lobe, and the medial segment was significantly higher in the CR group than in the non-CR group in the Child-Pugh grade A patients(0.82 vs 0.62, P < 0.001; 0.71 vs 0.59, P < 0.01; 0.81 vs 0.49, P < 0.05, respectively). However, there was no significant difference in the median location coefficient of the HCC in the lateral segment between in the CR and in the non-CR groups(0.67 vs 0.65, P > 0.05). On the other hand, in the Child-Pugh grade B patients, the HCC median location coefficient in each lobe and segment was not significantly different between in the CR and in the non-CR groups.CONCLUSION Improved TACE efficacy may be obtained for HCC in the peripheral zone of the right lobe and the medial segment in Child-Pugh grade A patients.Izumi Miki Satoru Murata Fumio Uchiyama Daisuke Yasui Tatsuo Ueda Fumie Sugihara Hidemasa Saito Hidenori Yamaguchi Ryusuke Murakami Chiaki Kawamoto Eiji Uchida Shin-ichiro Kumita 2017World Journal of Gastroenterology2017,23,35:8

14Neoatherosclerosis:Coronary stents seal atherosclerotic lesions but result in making a new problem of atherosclerosis显示文摘Chronic inflammation of the native vessel wall with infiltration of lipid-laden foamy macrophages through impaired endothelium results in atherosclerosis. Percutaneous coronary intervention, including metallic stent implantation, is now widely utilized for the treatment of atherosclerotic lesions of the coronary artery. Baremetal stents and the subsequently developed drugeluting stents seal the atherosclerosis and resolve lumen stenosis or obstruction of the epicardial coronary artery and myocardial ischemia. After stent implantation, neointima proliferates within the stented segment. Chronic inflammation caused by a foreign body reaction to the implanted stent and subsequent neovascularization, which is characterized by the continuous recruitment of macrophages into the vessel, result in the transformation of the usual neointima into an atheromatous neointima. Neointima with an atherosclerotic appearance, such as that caused by thin-cap fibroatheromas, is now recognized as neoatherosclerosis, which can sometimes cause in-stent restenosis and acute thrombotic occlusion originating from the stent segment following disruption of the atheroma. Neoatherosclerosis is emerging as a new coronary stent-associated problem that has not yet been resolved. In this review article, we will discuss possible mechanisms, clinical challenges, and the future outlook of neoatherosclerosis.Hidenori Komiyama Masamichi Takano Noritake Hata Yoshihiko Seino Wataru Shimizu Kyoichi Mizuno 2015World Journal of Cardiology2015,7,11:7
15Lessons from tenascin-C knockout mice and potential clinical application to subarachnoid hemorrhage显示文摘Subarachnoid hemorrhage by a ruptured cerebral aneurysmremains the most devastating cerebrovascular disorderswith high morbidity and mortality (Suzuki et al.,2017), which are mainly caused by early brain injury anddelayed cerebral ischemia. Despite many experimentaland clinical research efforts, the mechanisms of earlybrain injury as well as delayed cerebral ischemia remainunclarified. However, recent works have suggested thattenascin-C, which is a special type of secreted extracellularmatrix proteins, is promising as a novel therapeutictarget against post-subarachnoid hemorrhage early braininjury and delayed cerebral ischemia.Masato Shiba Hidenori Suzuki 2019Neural Regeneration Research2019,14,2:7
16An experimental study on self-output-control characteristics of micro downwind rotor with coning soft blades显示文摘In this short paper,we have treated the aerodynamic performance of micro downwind rotor with coning soft blades experimentally.The test wind rotor has the tip diameter of 1.5 m and three two-dimensional NACA0018 blades of 0.15 m chord whose material is light,soft and pliable foam plastic for perfect safety.From the wind tunnel test,it is realized that the performance is manageable by the coning angle of the rotor blade.In the present case,an improvement of the performance in lower wind speeds is achieved by using the coning blade of 20°.Besides,owing to the torsional deformation of very soft blade,the self-power control characteristic is observed in every test rotor regardless of coning angle in the range of 0°-20° under the wind speed less than 12 m/s.EGUCHI Hidenori YOSHIDA Kouichi NISHI Michihiro 2010Science China(Technological Sciences)2010,53,1:6
17miR-122-5p as a novel biomarker for alpha-fetoproteinproducing gastric cancer显示文摘AIM To investigate the clinical utility of alpha-fetoprotein(AFP)-producing gastric cancer(AFPGC)-specific microRNA(mi RNA)for monitoring and prognostic prediction of patients.METHODS We performed a comprehensive miRNA array-based approach to compare miRNA expression levels between AFP-positive and AFP-negative cells in three patients with primary AFPGC.We next examined the expression levels of the selected miRNAs in five AFPGC and ten non-AFPGC tissue samples by quantitative reverse transcription-polymerase chain reaction to validate their utility.We also investigated the expression levels of the selected miRNA not only in tissue but also in plasma samples.Moreover,we investigated the relationship between plasma AFP levels and plasma selected miRNA expression levels,and also investigated the correlation of the selected miRNA expression levels and malignant potential.RESULTS Among the five miRNAs selected from the miRNA array results,the expression levels of miR-122-5p were significantly higher in the AFPGC patients than in the non-AFPGC patients(P<0.05).In tissue samples,mi R-122-5p expression level tended to be lower in the non-AFPGC tissue than the normal gastric mucosa.Conversely,in the AFPGC tissue,miR-122-5p expression level was significantly higher in the AFPGC tissue than both the normal gastric mucosa and the nonAFPGC tissue samples(P<0.05).Plasma mi R-122-5p expression levels were also significantly higher in the AFPGC patients than the health volunteers and the nonAFPGC patients(P<0.05)and were strongly correlated with plasma AFP levels(r=0.7975,P<0.0001).Moreover,the correlation of miR-122-5p expression in tissue samples with malignant potential was stronger than that of plasma AFP level in the AFPGC patients.In contrast,no correlation was found between mi R-122-5p expression levels and liver metastasis in the non-AFPGC patients.CONCLUSION miR-122-5p might be a useful biomarker for early detection and disease monitoring in AFPGC.Suguru Maruyama Shinji Furuya Kensuke Shiraishi Hiroki Shimizu Hidenori Akaike Naohiro Hosomura Yoshihiko Kawaguchi Hidetake Amemiya Hiromichi Kawaida Makoto Sudo Shingo Inoue Hiroshi Kono Daisuke Ichikawa 2018World Journal of Gastrointestinal Oncology2018,10,10:6

20Occurrence of emerging flame retardants from e-waste recycling activities in the northern part of Vietnam显示文摘This study investigated the contamination status of 21 emerging flame retardants(FRs)in soils(n=32)and river sediments(n=8)from an e-waste recycling(EWR)site in the northern part of Vietnam.Among analyzed FRs,higher levels of decabromodiphenyl ethane(DBDPE)(NDe4200 ng/g dw),1,2-bis-(2,4,6-tribromophenoxy)ethane(BTBPE)(NDe350 ng/g dw)and Dechlorane Plus isomers(DPs)(NDe65 ng/g dw)were found in soils near EWR workshops and open burning places.The highest concentrations of DBDPE(20 ng/g dw),BTBPE(5.7 ng/g dw)and DPs(6.7 ng/g dw)were also detected in sediments collected from the middle of the EWR site.The levels decreased concomitantly with increasing distance from the EWR site.These results indicate that these FRs were released to the surrounding environment from improper recycling activities,such as manual dismantling of devices and open burning of e-wastes.Moreover,the estimated daily intakes of those FRs via soil ingestion were approximately ten times higher for children than adults.To our knowledge,this is a first comprehensive study on characterization of soil and sediment contamination by a series of emerging FRs at an EWR site in Vietnam.Masayuki Someya Go Suzuki Alin C.Ionas Nguyen Minh Tue Fuchao Xu Hidenori Matsukami Adrian Covaci Le Huu Tuyen Pham Hung Viet Shin Takahashi Shinsuke Tanabe Hidetaka Takigami 2016Emerging Contaminants2016,2,2:5
