How membrane curvature influences lipid distribution is under intensive research. In this short report, after a brief review of recent studies, the results of our coarse-grained (CG) molecular dynamics simulations of membranes with “hemifused ribbons” geometry are discussed. When membranes of a binary mixture of (dipalmitoyl-phosphatidylcholine (DPPC) / dioleoyl-phosphatidylethanolamine (DOPE) ...
Antimicrobial peptides are promising candidates as future therapeutics in order to face the problem of antibiotic resistance caused by pathogenic bacteria. Myxinidin is a peptide derived from the hagfish mucus displaying activity against a broad range of bacteria. We have focused our studies on the physico-chemical characterization of the interaction of myxinidin and its mutant WMR, which conta...
The organization of lipids and proteins into domains in cell membranes is currently an established subject within biomembrane research. Fluorescent probes have been used to detect and characterize these membrane lateral heterogeneities. However, a comprehensive understanding of the link between the probes' fluorescence features and membrane lateral organization can only be achieved if their pho...
Multifunctional, lipopolyplex formulations comprising a mixture of cationic liposomes and cationic, receptor-targeting peptides have potential use in gene therapy applications. Lipopolyplex formulations described here are typically far more efficient transfection agents than binary lipoplex or polyplex formulations. It has been shown previously that the peptide component mediates both DNA packa...
The mechanism by which hyaluronic acid (HA)-bearing lipoplexes target the A549 lung cancer cell line was evaluated. For this purpose, cationic liposomes targeting the CD44 receptor were designed thanks to the incorporation in their composition of a conjugate between high molecular weight HA and the lipid DOPE (HA-DOPE). Liposomes containing HA-DOPE were complexed at different lipids:DNA ratios ...
در این تحقیق با بهرهگیری از نظریه تابع چگالی (DFT)، روش B3LYP و سری پایه G* 6-31 اثر جذب مولکولهای CO, ClCN, HCN را روی نانولولههای تک دیواره آرمچیر (4 و 4) SiC دوپه شده با اتم B مورد بررسی قرار گرفته است. با توجه به روند تغییرات در فاصله بین اوربیتالهای HOMO و LUMO مدلهای مورد مطالعه میتوان نتیجه گرفت که بیشترین رسانایی الکتریکی در مدل B dope C ClCN-Attached و کمترین رسانایی در مدل خا...
The DOPE project (Drug Ontology Project for Elsevier) is driven by the need to access multiple information sources through a single interface. In this paper, we describe how DOPE allows thesaurus-driven access to heterogeneous and distributed data, based on the RDF data model. The architecture allows for the easy addition of thesauri and data sources, and can facilitate explorations in ontology...
objective(s): although several chemical and physical methods for gene delivery have been introduced, their cytotoxicity, non-specific immune responses and the lack of biodegradability remain the main issues. in this study, hydroxyapatite nanoparticles (nps) and 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine (dope)-modified hydroxyapatite nps was coated with antisense oligonucleotide of e6 mrna...
