Microalgae Scenedesmus obliquus as renewable biomass feedstock for electricity generation in microbial fuel cells （MFCs）

引用

Frontiers of Environmental Science & Engineering 2014年第5期8卷 784-791页

作者： Sanath KONDAVEETI Kwang Soon cho Ramesh KAKARLA Booki MIN Department of Environmental Science and Engineering Kyung Hee University Gyeonggi-do 446-701 Republic of Korea

Renewable algae biomass, Scenedesmus obliquus, was used as substrate for generating electricity in two chamber microbial fuel cells （MFCs）. From polarization test, maximum power density with pretreated algal biomass was 102mW·m^2 （951mW·m^3） at current generation of 276mA·m^-2. The individual electrode potential as a function of current generation suggested that anodic oxidation process of algae substrate had limitation for high current generation in MFC. Total chemical oxygen demand （TCOD） reduction of 74% was obtained when initial TCOD concentration was 534mg · L^-1 for 150 h of operation. The main organic compounds of algae oriented biomass were lactate and acetate, which were mainly used for electricity generation. Other byproducts such as propionate and butyrate were formed at a negligible amount. Electrochemical Impedance Spectroscopy （EIS） analysis pinpointed the charge transfer resistance （112Ω ） of anode electrode, and the exchange current density of anode electrode was 1214 nA·cm^-2.

重庆邮电大学学报（自然科学版） 2007年第3期19卷 386-391页

作者： HUANG Dong-li yuAN Zheng-wu Byeong-Seob You Sook-kyung cho Hae-Young Bae College of Computer Science and Technology Chongqing University of Posts and Telecommunications Chongqing 400065 P. R. China Department of Computer Science and Information Engineering Inha UniversityIncheon 402-751 Korea

Using Networked RFID equipped in warehouse or supermarket distribution, Enterprise information system (EIS) can gather and deal with cargos information. Nevertheless, when cargos are in traffic, the Networked RFID can’t monitor the cargos any more as the products tagged aren’t within range of a reader. This paper proposes a solution framework which combines Networked RFID and GPS tracking, and then equip with this system in container to make the cargos monitored even if the cargos are in traffic. This solution can solve the accurate consignments, position tracking and advanced theft happening through drilling holes in container. In addition, customhouse and checkpoint can get an electronic shipment manifest rapidly and safely when a vehicle gets through a checkpoint.

Severe acute pancreatitis due to tamoxifen-induced hypertriglyceridemia with diabetes mellitus

引用

Chinese Journal of Cancer Research 2014年第3期26卷 341-344页

作者： Young Ae Kim Sol Lee Ji Woong Jung yu Jin Kwon Gyeong Bok Lee Dong Gue Shin Sang Su Park Jin yun Yong-Seog Jang Dong Hui cho Department of Surgery Seoul Medical CenterSeoulKorea Department of Surgery Red Cross HospitalSeoulKorea

The side effects of tamoxifen are generally mild, including the effect on lipoprotein metabolism. However, there are few cases of severe tamoxifen induced hypertriglyceridemia. Hypertriglyceridemia is a marked risk factor for acute pancreatitis and approximately 2% to 5% of cases of acute pancreatitis are related to drugs. We report on tamoxifen-induced hypertriglyceridemia and acute pancreatitis in a 40 years old woman with type 2 diabetes mellitus occurred by dexamethasone. She was treated with insulin infusion and fenofibrate, and goserelin acetate was started instead of tamoxifen after discharge from the hospital. Also, probable pathogenic hypotheses about the correlation between tamoxifen and dexamethasone induced type 2 diabetes mellitus on severe acute pancreatitis are provided. Clinicians should take care of risks of severe acute pancreatitis on using tamoxifen, especially for patients with dexamethasone induced diabetes mellitus. These individuals should undergo pre-post tamoxifen lipid screening and careful history taking of drugs, including dexamethasone.

目的:研究苦参提取物对大鼠离体胸主动脉的作用及其机制。方法:以大鼠胸主动脉为标本,以敏感的离体药理学实验方法记录血管平滑肌张力。利用一氧化氮合酶抑制剂、可溶性鸟苷酸环化酶抑制剂、钙通道阻断剂、钾通道阻断剂、环氧化酶抑制剂M胆碱受体的阻断等工具药,研究血管内皮、钙通道和钾通道、自主神经系统等对苦参提取物扩血管作用的影响。结果:苦参提取物(10～10 g/mL)能显著舒张PE预收缩的血管;去内皮后,苦参提取物的舒血管作用显著减弱。在内皮完整的情况下,L-NAME、ODQ和地尔硫卓能抑制苦参提取物的舒血管作用;吲哚美辛、格列本脲和四乙基氯化铵、阿托品和普萘洛尔不影响苦参提取物的舒血管作用。苦参提取物对内皮完整血管环能剂量依赖性地显著增高cGMP含量。结论:苦参提取物具有内皮依赖性舒张血管作用,且主要通过NO-cGMP信号途径发挥作用。

A System for Improving the Management of the Lesion and Test Images of Patients

引用

Engineering（科研） 2013年第10期5卷 163-165页

作者： Sung-Bum cho kyung-Won Jin Jong-Soon Kim Soo-Jin Huh Segyeong Joo Department of Biomedical Engineering Asan Medical Center Seoul Korea Department of Biomedical Engineering Asan Medical Center Seoul Korea Department of Biomedical Engineering University of Ulsan College of Medicine Seoul Korea

Nowadays, almost every hospital utilizes picture archiving and communications system (PACS) and electronic medical record (EMR) system to manage patient’s data digitally. However, patient’s pictures taken by nurses or physicians to monitor lesions or various test results are not managed well in general. Although for some disease, these pictures provide meaningful information in diagnosis and treatment. In this paper, we propose a management system for these images to improve the accessibility and storability. To manage the images efficiently, the proposed methods utilized the PACS system in the hospital. After sending the image data of each patient to a local monitoring computer, the patient’s information, such as, name, age, male, and registration number were attached on the image. This file was then converted to a DICOM (digital imaging and communications in medicine) files and transferred to the PACS Server. The proposed system promises easy and convenient access on the images of lesions and various test results of patients to support fast and appropriate treatment.

Effects of feeding a diet containing Gymnema sylvestre extract: attenuating progression of obesity in C57BL/6J mice

引用

Asian Pacific Journal of Tropical Medicine 2016年第5期9卷 425-431页

作者： Hyeon-Jeong Kim Seong-Ho Hong Seung-Hee Chang Sanghwa Kim Ah Young Lee Yoonjeong Jang Orkhonselenge Davaadamdin Kyeong-Nam yu Ji-Eun Kim Myung-Haing cho Laboratory of Toxicology College of Veterinary Medicine Seoul National University Graduate Group of Tumor Biology Seoul National University Graduate School of Convergence Science and Technology Seoul National University Advanced Institutes of Convergence Technology Seoul National University Institute of Green Bio Science Technology Seoul National University

Objective: To investigate the effect of Gymnema sylvestre extract(GS) on initial anti-obesity, liver injury, and glucose homeostasis induced by a high-fat diet(HFD). Methods: The dry powder of GS was extracted with methanol, and gymnemic acid was identified by high performance liquid chromatography as deacyl gymnemic acid. Male C57BL/6J mice that fed on either a normal diet, normal diet containing 1 g/kg GS(CON+GS) HFD, or HFD containing 1.0 g/kg GS(HFD+GS) for 4 weeks were used to test the initial anti-obesity effect of GS. Body weight gain and food intake, and serum levels about lipid and liver injury markers were measured. Histopathology of adipose tissue and liver stained with hematoxylin and eosin(H&E) and oil-red O were analyzed. After 4 weeks of GS extract feeding, intraperitoneal glucose tolerance test(IPGTT) was performed. Results: The methanol extracts of GS exerted significant anti-obesity effects in HFD+GS group. They decreased body weight gain, a lower food and energy efficiency ratio, and showed lower serum levels of total cholesterol(TC), triglyceride(TG), low-density lipoprotein(LDL)-cholesterol, very-low density lipoprotein(VLDL)-cholesterol and leptin compared with the HFD group. The decreases of abdominal as well as epididymal fat weight and adipocyte hypertrophy, lipid droplets in liver, and serum levels of aspartate aminotransferase(AST) and alanine transaminase(ALT) were also observed. The CON+GS group showed an effect of glucose homeostasis compared to the CON group. Conclusions: This study shows that GS provide the possibility as a key role in an initial anti-obesity effects feeding with a HFD.

试验旨在探讨饲料中不同钙磷水平对禾花鲤生长性能、血清生化指标、骨骼及肝脏组织形态的影响。试验以氯化钙为钙源设2个钙水平:0、0.5%(A、B),以磷酸二氢钾为磷源设4个磷水平:0、0.5%、1.0%、1.5%(1、2、3、4),采用交叉组合制备A1(0钙、0磷)、A2(0钙、0.5%磷)、A3(0钙、1.0%磷)、A4(0钙、1.5%磷)、B1(0.5%钙、0磷)、B2(0.5%钙、0.5%磷)、B3(0.5%钙、1.0%磷)、B4(0.5%钙、1.5%磷)8组等氮饲料,选择初始体重为(4.46±0.02) g的禾花鲤1 440尾,随机分为8组,每组3个重复,每个重复60尾鱼,养殖60 d。试验结果表明:(1)禾花鲤的终末体重(FBW)、增重率(WGR)、特定生长率(SGR)在钙磷水平分别为0.5%、1.5%(B4)时达最大值,显著大于A4和B1组(Pcho)含量随饲料磷水平升高呈降低趋势。(4) X光片显示,A1组脊椎骨发生融合,A3、A4和B1组尾脊椎骨发生不同程度畸形。(5)当饲料钙水平为0时,饲料磷水平升高可缓解肝细胞空泡化,当磷水平为1.5%时造成脂肪堆积和核偏移;当钙水平为0.5%时,饲料磷水平升高可减少肝细胞损伤,且肝细胞完整性更好。综上所述,建议禾花鲤饲料钙磷水平分别为0.5%、1.0%~1.5%,有利于禾花鲤的生长及鱼体健康。
