Stm Of Glow-Discharge Treated Surfaces
(Marcel Dekker Inc, 1993)As a model surface, graphite slides were treated by pure nitrogen gas plasma for different periods (15 sec - 5 min). These samples were kept in air or under argon atmosphere in sealed holders. STM images were obtained at ... -
Formation Of Supramolecular Structures By Negatively Charged Liposomes In The Presence Of Nucleic Acids And Divalent Cations
(Taylor & Francis Inc, 1998)Cationic liposomes are being increasingly studied as delivery vehicles for bioactive agents such as DNA and other polynucleotides, The mechanism of interaction of DNA with liposomes and the organization of these interacting ... -
In Vitro Transfection Of Hela Cells With Temperature Sensitive Polycationic Copolymers
(Elsevier Science Bv, 2004)In this study, we investigated different types of polyethyleneimine (PEI) and their block copolymers with N-isopropylacrylamide (NIPA) as temperature-sensitive polycationic non-viral vectors for transfection of HeLa cells ... -
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 ... -
Synthesis and Characterization of Novel Thiourea Derivatives and their Nickel and Copper Complexes
(Hindawi Ltd, 2013)New benzoyl thiourea derivatives and their nickel and copper complexes were synthesized. The structure of the synthesized compounds were confirmed by elemental analysis, FT-IR, and H-1 NMR techniques. Four of the synthesized ... -
Synthesis and Molecular Modeling Studies of Naproxen-Based Acyl Hydrazone Derivatives
(Scientific Technical Research Council Turkey-Tubitak, 2015)A series of N-acylhydrazone derivatives (2a-2p) containing 6-methoxy-naphthalene and acylhydrazone moieties were synthesized in good yield using microwave irradiation and developed as potential COX-2 inhibitors. Furthermore, ... -
The Influence Of Documentary Films On 8Th Grade Students' Views About Nature Of Science
(Edam, 2015)This quasi-experimental study aims to investigate the documentary films influence on 8th grade students nature of science views. The studys participants were 113 8th grade students from two different schools taught by two ... -
Multifunctional Electroactive Electrospun Nanofiber Structures From Water Solution Blends Of Pva/Oda-Mmt And Poly(Maleic Acid-Alt-Acrylic Acid): Effects Of Ag, Organoclay, Structural Rearrangement And Naoh Doping Factors
