Specific Radius Change of Quantum Dot inside the Lipid Bilayer by Charge Effect of Lipid Head-Group

引用

Open Journal of Biophysics 2018年第3期8卷 163-175页

We studied the quantum dot-liposome complex (QLC), which is the giant unilamellar vesicle with quantum dots (QDs) incorporated in its lipid bilayer. A spin coating method in conjunction with the electroformation technique yielded vesicles with highly homogeneous unilamellar structure. We observed QD size dependence of the QLC formation: QLCs form with blue, green and yellow-emission QD (core radius ~1.05 nm, 1.25 nm and 1.65 nm) but not with red-emission QD (core radius ~2.5 nm). In order to explain this size dependence, we made a simple model explaining the QD size effect on QLC formation in terms of the molecular packing parameter and the lipid conformational change. This model predicts that QDs below a certain critical size (radius ≈ 1.8 nm) can stably reside in a lipid bilayer of 4 - 5 nm in thickness for Egg-PC lipids. This is consistent with our previous experimental results. In the case of red-emission QD, QD-aggregations are only observed on the fluorescent microscopy instead of QLC. We expected that the reduction of packing parameter (P) would lead to the change of specific QD radius. This prediction could be verified by our experimental observation of the shift of the specific QD size by mixing DOPG.

Journal of Applied Mathematics and Physics 2016年第8期4卷 1499-1502页

作者： Sang hun Shin Young Beom Song Mingeon kim Hye Jin kim Wook Jae Yoo Kyoung Won Jang Bongsoo Lee School of Biomedical Engineering BK21 Plus Research Institute of Biomedical Engineering Konkuk University Chungju-si Korea School of Energy Systems Engineering Chung-Ang University Seoul Korea

In this study, we fabricated a Cerenkov fiber-optic dosimeter (CFOD) without any scintillator to measure Cerenkov radiation signals owing to gamma-rays. The relative depth dose (RDD) distributions of Ir-192 HDR brachytherapy source were obtained by using the CFOD based on a subtraction method and the RDD curve was compared with the simulation result of Monte Carlo N-particle extended transport code (MCNPX). Finally, we demonstrated that the CFOD can be used to measure real-time dose information for HDR brachytherapy.

Tetrahydroisoquinolines are known to have various biological effects, including antitumor activity. This study investigated the effect of 1-chloromethyl-6, 7-dimethoxy-3, 4-dihydro-1H-isoquinoline-2-sulfonic acid amide (CDST), a newly synthesized anticancer agent, on cellular differentiation and proliferation in HL-60 cells. Differentiation and proliferation of HL-60 cells were determined through expression of CD11b and CD14 surface antigens using flow cytometry and nitroblue tetrazolium (NBT) assay, and through analysis of cell cycle using propidium iodide staining, western blot analysis and immunoprecipitation, respectively. CDST induced the differentiation of HL-60, as shown by increased expression of differentiation surface antigen CD11b (but no significant change in CD14 expression) and increased NBT-reducing functional activity. DNA flow cytometry analysis indicated that CDST markedly induced a G0/G1 phase arrest of HL-60 cells. Subsequently, we examined the expre-ssion of G0/G1 phase cell cycle-related proteins, including cyclin-dependent kinases (CDKs), cyclins and cyclin dependent kinase inhibitors (CKIs), during the differentiation of HL-60. The levels of CDK2, CDK6, cyclin E and cyclin A were decreased, whereas steady-state levels of CDK4 and cyclin D1 were unaffected. The expression of the p27Kip1 was markedly increased by CDST, but not p21WAF1/Cip1. Moreover, CDST markedly enhanced the binding of p27Kip1 with CDK2 and CDK6, resulting in the reduced activity of both kinases. Taken together, these results demonstrate that CDST is capable of inducing cellular differentiation and growth inhibition through p27Kip1 protein-related G0/G1 phase arrest in HL-60 cells.

AIM : To systematically evaluate the effect of intraperitoneal local anesthetic on pain characteristics after laparoscopic cholecystectomy(LC).METHODS: We searched MEDLINE, EMBASE, and the Cochrane Library. Randomized controlled trials in English that compared the effect of intraperitoneal administration of local anesthetics on pain with that of placebo or nothing after elective LC under general anesthesia were included. The primary outcome variables analyzed were the combined scores of abdominal, visceral, parietal, and shoulder pain after LC at multiple time points. We also extracted pain scores at resting and dynamic ***: We included 39 studies of 3045 patients in total. The administration of intraperitoneal local anesthetic reduced pain intensity in a resting state after laparoscopic cholecystectomy: abdominal [standardized mean difference(SMD) =-0.741; 95%CI:-1.001 to-0.48, P < 0.001]; visceral(SMD =-0.249; 95%CI:-0.493 to-0.006, P = 0.774); and shoulder(SMD =-0.273; 95%CI:-0.464 to-0.082, P = 0.097). Application of intraperitoneal local anesthetic significantly reduced the incidence of shoulder pain(RR = 0.437; 95%CI: 0.299 to 0.639, P < 0.001). There was no favorable effect on resting parietal or dynamic abdominal ***: Intraperitoneal local anesthetic as an analgesic adjuvant in patients undergoing laparoscopic cholecystectomy exhibited beneficial effects on postoperative abdominal, visceral, and shoulder pain in a resting state.

In this study, we analyzed complete mtDNA sequences variation and genetic relationship among taurine, indicine and Bison groups. In total, 107 sequences from different breeds, 45 European (45 Italian), 16 Middle East Asian (seven Iranian and nine Iraqi), 41 Northeast Asian (34 Korean and seven Japanese), two Nellore (Bos indicus) and two American Bison bison (Ame. bison) were obtained from Gen-Bank database. One Korean Hanwoo (Bos taurus) sequence was generated using the SOLiDTM System. In total, 1370 polymorphic sites, representing 8.39% of the complete 107 mtDNA sequences (16,338 bp) were detected and of these, 1186 parsimony informative polymorphic sites were identified. Neighbor-joining tree indicated that Korean, Japanese, Iranian, Iraqi, and Italian cattle were closely related to one another, but are separated from B. Bison. The B. taurus mtDNA polymorphism was greater in the D-loop than in the other regions. The ATP8, ND3, ND5, and ND6 regions were also quite parsimony informative, similar to Cyt b. In addition, this study revealed a distinct genetic difference between Korean cattle and B. indicus.

Thioredoxin Reductase Type C （NTRC） Orchestrates Enhanced Thermotolerance to Arabidopsis by Its Redox-Dependent Holdase Chaperone Function

引用

Molecular Plant 2013年第2期6卷 323-336页

作者： Ho Byoung Chae Jeong Chan Moon Mi Rim Shin Yong hun Chi Young Jun Jung Sun Yong Lee Ganesh M. Nawkar Hyun Suk Jung Jae Kyung Hyun Woe Yeon kim Chang Ho Kang Dae-Jin Yun Kyun Oh Lee Sang Yeol Lee Division of Applied Life Science (BK21 Program) and PMBBRC Gyeongsang National University 501 Jinju-daero Jinju 660-701 Korea Division of Electron Microscopic Research Korea Basic Science Institute 113 Gwahangno Yuse0ng-guDaejeon 303-333 Korea

Genevestigator analysis has indicated heat shock induction of transcripts for NADPH-thioredoxin reduc-tase, type C （NTRC） in the light. Here we show overexpression of NTRC in Arabidopsis （NTRC°E） resulting in enhanced tolerance to heat shock, whereas NTRC knockout mutant plants （ntrcl） exhibit a temperature sensitive phenotype. To investigate the underlying mechanism of this phenotype, we analyzed the protein＇s biochemical properties and protein structure. NTRC assembles into homopolymeric structures of varying complexity with functions as a disulfide reductase, a foldase chaperone, and as a holdase chaperone. The multiple functions of NTRC are closely correlated with protein structure.. Complexes of higher molecular weight （HMW） showed stronger activity as a holdase chaperone, while low molecular weight （LMW） species exhibited weaker holdase chaperone activity but stronger disulfide reductase and fol-dase chaperone activities. Heat shock converted LMW proteins into HMW complexes. Mutations of the two active site Cys residues of NTRC into Ser （C217/454S-NTRC） led to a complete inactivation of its disulfide reductase and foldase chaperone functions, but conferred only a slight decrease in its holdase chaperone function. The overexpression of the mutated C217/454S-NTRC provided Arabidopsis with a similar degree of thermotolerance compared with that of NTRC°E plants. However, after prolonged incubation under heat shock, NTRC°E plants tolerated the stress to a higher degree than C217/454S-NTRC°E plants. The results suggest that the heat shock-mediated holdase chaperone function of NTRC is responsible for the increased thermotolerance of Arabidopsis and the activity is significantly supported by NADPH.
