长江将大量泥沙排入东海,对杭州湾的沉积演变产生重大影响,但长江型碎屑对杭州湾不同时期、不同位置的贡献差异缺乏研究。通过分析杭州湾舟山海域水下钻孔(HZW1907孔)沉积物中有机、无机元素地球化学特征,对杭州湾沉积过程中的水体古盐度、源区风化过程、沉积物组成与来源和长江–杭州湾–东海陆架沉积系统进行研究,并基于稀土元素组成的两端元混合模型,定量探讨长江泥沙对杭州湾不同位置沉积的贡献程度差异。结果表明,杭州湾湾口从晚更新世以来,经历了冰期的下切河谷深切、河谷充填和河谷埋藏3个阶段演化过程,相应发育了河床相(约33.9~23.7kaBP)、河漫滩相(约23.7~12.0kaBP)、古河口湾相(约12.0~9.0 ka BP)、浅海相(约9.0~4.0 ka BP)和现代河口湾相(约4.0 ka BP至今);沉积物的Ga/Rb和K_(2)O/Al_(2)O_(3)关系揭示了中国东部在33.9 ka BP以来经历了冷干–暖湿的气候变化;Ts和TOC的变化反映了淡水–不稳定淡水、海水混合–稳定海水的沉积水体演替,与东海陆架一致。晚更新世期间,杭州湾地区发育的河床相、河漫滩相沉积物源区主要来自钱塘江流域,显示长英质火成岩的特征;全新世以来的古河口湾相、浅海相和现代河口湾相沉积物为钱塘江型碎屑与长江型碎屑的混合,显示中基性火成岩的特征,湾口受到长江物质的影响更强。以长江和钱塘江流域(Gd/Yb)_(UCC)为端元的模拟结果显示,杭州湾湾口与湾顶受到长江物质影响差异较大,古河口湾相时期,长江供给杭州湾湾口沉积物约78%,湾顶约39%;浅海相时期,长江供给杭州湾地区超过80%的碎屑,湾口、湾顶无明显差别;现代河口湾相时期,长江供给湾口沉积物约76%,湾顶约22%。该模拟方法在长江向杭州湾输送的碎屑分析中具有定量化的作用,并有望适用于其他沿海陆架河流系统。

中国肺癌杂志 2020年第5期23卷 321-332页

作者： Arif R HANAFI Achmad m JAYUsmAN serafim ALFAsUNU Ahmad H sADEWA Dibyo PRAmONO Didik s HERIYANTO sofia m HARYANA Department of Pulmonology "Dharmais"Hospital National Cancer CenterJakarta 11420Indonesia Faculty of medicine Gadjah Mada UniversityYogyakarta 55281Indonesia

Background and objective Lung cancer is the most common cause of death in men in the world and in Indonesia where nonsmall cell carcinoma lung cancer(NsCLC) constitutes 85% of all lung cancer cases. The high mortality rate is due to a poor prognosis and is often diagnosed as having advanced stages. If it is known at the initial stage, the prognosis of lung cancer will be better. Prognosis can be predicted with a marker of prognostic biology, one of which is micro RNA(mi RNA). This study aims to prove that serum mi RNA can be predictive biological marker and prognosis in NsCLC patients in *** This study was cohort retrospective among 52 subjects in "Dharmais" Hospital National Cancer Center. sample was obtained from patients’ serum. mi R-34, mi R-148, mi R-155 and mi R-222 serum are measured through Real-Time PCR(q PCR). Data were analyzed and interpreted with descriptive analysis, bivariate analysis(mann Whitney-U for two type of variables or Kruskal-Wallis for more than two type of variables. Kaplan-meier analysis was used to know association between characteristic which are sociodemographic, performance status, clinico-pathology, and survival rate in mi RNA expression. Results From this study, mi RNA expression: mi R-34(46.15%), mi R-148(23.08%), mi R-155(40.38%) and mi R-222(32.69%). Performance status score was statistically significant correlation with mi R-148(P=0.049) and mi R-222(P=0.018). High mi R-34 is associated with multiple m1 b metastatic type(P=0.020), cancer cell type(adenocarcinoma, P=0.009) and adenocarcinoma epidermal growth factor receptor(EGFR) mutation(negative, P=0.031). There was a significant correlation between the high mi R-222 as a poor prognosis in advanced stage NsCLC with m1 b metastasis(median survival/ms: 27 d, P=0.049) and positive EGFR mutations(ms: 74 d, P=0.049) and correlation of mi R-155 with adenocarcinoma(ms: 69 d, P=0.034) and positive EGFR gene mutations(ms: 58 d, P=0.023).Conclusion High mi R-34 expression i

Role of surfactants on particle deposition, wear, and corrosion behavior of TaC particle incorporated electroless nickel-phosphorus coating

引用

Progress in Natural science:materials International 2022年第5期32卷 655-663页

作者： Jin-Hyuk choi Dhani Ram Dhakal Yuwaraj K.Kshetri Bina Chaudhary Bhupendra Joshi soo Wohn Lee Tae-Ho Kim Research Center for Advance Green materials Sun Moon University Department of Fusion science and Technology Sun Moon University

The coatings prepared by incorporating submicron-sized TaC particles while depositing Ni and P atoms on the steel substrate via electroless method showed mixed results of surface finishing, microstructural properties,mechanical, tribological, and corrosion behavior with the addition of various surfactants during the coating process. The surfactant sodium dodecyl sulfate(sDs) enhanced the microhardness when added during the coating process of Ni–P–TaC composite, whereas the cetyltrimethyl ammonium bromide(CTAB) lowered the microhardness as compared to the surfactant-free coating. moreover, the TaC particle incorporation was hindered by the surfactants CTAB and Triton X-100. An excellent wear resistance behavior has been observed in the surfactantfree Ni–P–TaC coating in comparison to particle-free Ni–P coating. The Ni–P–TaC coatings showed the dependency of wear behavior on the material properties of the counter sliding surface although this dependency has not been observed in Ni–P coatings. The wear damage in Ni–P coating is immense irrespective of the properties of counter-sliding materials. Various surfactant-used Ni–P–TaC coating surfaces deteriorated much more due to corrosion than surfactant-free Ni–P–TaC coating. Among the various surfactants, the CTAB used Ni–P–TaC coating showed weak corrosion resistance.

Induction of clusterin Expression by Neuronal Cell Death in Zebrafish

Clusterin, a protein associated with multiple functions, is expressed in a wide variety of mammalian tissues. Although clusterin is known to be involved in neurodegenerative diseases, ageing, and tumorigenesis, a detailed analysis of the consequences of gain- or loss-of- function approaches has yet to be performed to understand the underlying mechanisms of clusterin functions. since clusterin levels change in neurological diseases, it is likely that clusterin contributes to cell death and degeneration in general. Zebrafish was investigated as a model system to study human diseases. During development, zebrafish clusterin was expressed in the notochord and nervous system. Embryonic overexpression of clusterin by mRNA microinjection did not affect axis formation, whereas its knock-down by anti-sense morpholino treatment resulted in neuronal cell death. To analyze the function of clusterin in neurodegeneration, a transgenic zebrafish was investigated, in which nitroreductase expression is regulated under the control of a neuron-specifc huC promoter which is active between the stages of early neuronal precursors and mature neurons. Nitroreductase turns metronidazole into a cytotoxic agent that induces cell death within 12 h. After metronidazole treatment, transgenic zebrafish showed neuron-specific cell death. Interestingly, we also observed a dramatic induction of clusterin expression in the brain and spinal cord in these fish, suggesting a direct or indirect role of clusterin in neuronal cell death and thus, more generally, in neurodegeneration.

Effect of preoperative biliary drainage on surgical results after pancreaticoduodenectomy in patients with distal common bile duct cancer:Focused on the rate of decrease in serum bilirubin

引用

World Journal of Gastroenterology 2008年第7期14卷 1102-1107页

作者： Yun mee choi Eung-Ho Cho Keon-Young Lee seung-Ik Ahn sun Keun choi sei Joong Kim Yoon seok Hur Young Up Cho Kee-Chun Hong seok-Hwan shin Kyung Rae Kim Ze-Hong Woo Department of surgery College of MedicineInha UniversityIncheonKorea

AIm: To examine if the rate of decrease in serum bilirubin after preoperative biliary drainagecan be used as a predicting factor for surgical complications and postoperative recovery after pancreaticoduodenectomy in patients with distal common bile duct ***: A retrospective study was performed in 49 consecutive patients who underwent pancrea-ticoduodenectomy for distal common bile duct cancer. Potential risk factors were compared between the complicated and uncomplicated groups. Also, the rates of decrease in serum bilirubin were compared pre- and postoperatively. REsULTs: Preoperative biliary drainage (PBD) was performed in 40 patients (81.6%). Postoperative morbidity and mortality rates were 46.9% (23/49) and 6.1% (3/49), respectively. The presence or absence of PBD was not different between the complicated and uncomplicated groups. In patients with PBD, neither the absolute level nor the rate of decrease in serum bilirubin was significantly different. Patients with rapid decrease preoperatively showed faster decrease during the first postoperative week (5.5 ± 4.4 μmol/L vs -1.7 ± 9.9 μmol/L, P = 0.004).CONCLUsION: PBD does not affect the surgical outcome of pancreaticoduodenectomy in patients with distal common bile duct cancer. There is a certain group of patients with a compromised hepatic excretory function, which is represented by the slow rate of decrease in serum bilirubin after PBD.
