Intelligent Polymers as Nonviral Vectors
(Nature Publishing Group, 2005)The successful gene therapy largely depends on the vector type that allows a selective and efficient gene delivery to target cells with minimal toxicity. Nonviral vectors are much safer and cheaper, can be produced easily ... -
Formation And Organization Of Amino Terminated Self-Assembled Layers On Si(001) Surface
(2007)We have investigated the effects of dipping time, solution concentration and solvent type on the formation of self-assembled monolayers with aminosiloxane molecules (i.e.,N-(3 trimethoxysilylpropyl)diethylenetriamine (TPDA)) ... -
Synthesis and Characterization of Functional Copolymer/Organo-Silicate Nanoarchitectures Through Interlamellar Complex-Radical (Co)Terpolymerization
(Budapest Univ Technol & Econ, 2008)The functional copolymers, having a combination of rigid/flexible linkages and an ability of complex-formation with interlayered surface of organo-silicate, and their nanocomposites have been synthesized by interlamellar ... -
Endothelial Cell Colonization And Angiogenic Potential Of Combined Nano- And Micro-Fibrous Scaffolds For Bone Tissue Engineering
(Elsevier Sci Ltd, 2008)Presently the majority of tissue engineering approaches aimed at regenerating bone relies only on post-implantation vascularization. Strategies that include seeding endothelial cells (ECs) on biomaterials and promoting ... -
Comparative Chondrogenesis Of Human Cell Sources In 3D Scaffolds
(Wiley-Blackwell, 2009)Cartilage tissue can be engineered by starting from a diversity of cell sources, including stem-cell based and primary cell-based platforms. Selecting an appropriate cell source for the process of cartilage tissue engineering ... -
Synthesis of Hydroxyapatite by Using Calcium Carbonate and Phosphoric Acid in Various Water-Ethanol Solvent Systems
(Versita, 2009)The purpose of the present study is to synthesize hydroxyapatite by using CaCO(3) and H(3)PO(4) in various water-ethanol solvent systems. It was observed from experiments that formation of ammonium phosphate compounds ... -
Ring-Opening Copolymerization of L-Lactide and Epsilon-Caprolactone in Supercritical Carbon Dioxide Using Triblock Oligomers of Caprolactone and Peg As Stabilizers
(Nature Publishing Group, 2011)In this study, the use of triblock (A-B-A) oligomers of epsilon-caprolactone (epsilon-CL) (A) and PEG400 (B) as stabilizers (SB) for the copolymerization of L-lactide (LLA) and epsilon-CL in supercritical carbon dioxide ... -
Derivation, Characterization And Expansion Of Fetal Chondrocytes On Different Microcarriers
(Springer, 2011)Fetal chondrocytes (FCs) have recently been identified as an alternative cell source for cartilage tissue engineering applications because of their partially chondrogenically differentiated phenotype and developmental ... -
