Adhesion, Vitality and Osteogenic Differentiation Capacity of Adipose Derived Stem Cells Seeded on Nitinol Nanoparticle Coatings

Strauß, Sarah; Neumeister, Anne; Barcikowski, Stephan; Kracht, Dietmar; Kuhbier, Jörn W.; Radtke, Christine; Reimers, Kerstin; Vogt, Peter M. (San Francisco, California, US : PLOS, 2013)

Autologous cells can be used for a bioactivation of osteoimplants to enhance osseointegration. In this regard, adipose derived stem cells (ASCs) offer interesting perspectives in implantology because they are fast and easy ...
Characterization of a thermosensitive ribonucleotide reductase mutant derived from Corynebacterium ammoniagenes ATCC 6872 and its use in the production of nucleotides

Elhariry, Hesham (Hannover : Universität, 2004)

Comparative in vitro study and biomechanical testing of two different magnesium alloys

Weizbauer, Andreas; Modrejewski, Christian; Behrens, Sabine; Klein, Helmut; Helmecke, Patrick; Seitz, Jan-Marten; Windhagen, Henning; Möhwald, Kai; Reifenrath, Janin; Waizy, Hazibullah (London : SAGE Publications Ltd., 2014)

In this in vitro study, magnesium plates of ZEK100 and MgCa0.8 alloy similar to common titanium alloy osteosynthesis plates were investigated as degradable biomedical materials with a focus on primary stability. Immersion ...
Experimental microbial alteration and Fe mobilization from basaltic rocks of the ICDP HSDP2 drill core, Hilo, Hawaii

Stranghoener, Marius; Schippers, Axel; Dultz, Stefan; Behrens, Harald (Lausanne : Frontiers Media S.A., 2018)

The interaction of a single bacterial species (Burkholderia fungorum) with basaltic rocks from the ICDP HSDP2 drill core and synthetic basaltic glasses was investigated in batch laboratory experiments to better understand ...
Gold Nanoparticle Mediated Laser Transfection for Efficient siRNA Mediated Gene Knock Down

Heinemann, Dag; Schomaker, Markus; Kalies, Stefan; Schieck, Maximilian; Carlson, Regina; Murua Escobar, Hugo; Ripken, Tammo; Meyer, Heiko; Heisterkamp, Alexander (San Francisco, California, US : PLOS, 2013)

Laser based transfection methods have proven to be an efficient and gentle alternative to established molecule delivery methods like lipofection or electroporation. Among the laser based methods, gold nanoparticle mediated ...
Hydrogel-based microfluidics for vascular tissue engineering

Koroleva, Anastasia; Deiwick, Andrea; Nguyen, Alexander; Narayan, Roger; Shpichka, Anastasia; Kufelt, Olga; Kiyan, Roman; Bagratashvili, Victor N.; Timashev, Peter; Scheper, Thomas; Chichkov, Boris (Berlin : De Gruyter, 2016)

In this work, we have explored 3-D co-culture of vasculogenic cells within a synthetically modified fibrin hydrogel. Fibrinogen was covalently linked with PEG-NHS in order to improve its degradability resistance and ...
In situ static and dynamic light scattering and scanning electron microscopy study on the crystallization of the dense zinc imidazolate framework ZIF-zni

Hikov, Todor; Schröder, Christian A.; Cravillon, Janosch; Wiebcke, Michael; Huber, Klaus (Cambridge : Royal Society of Chemistry, 2012)

The kinetics and mechanism of crystallization of the dense zinc imidazolate framework with zni topology, from comparatively dilute methanol solutions containing Zn(NO3)·6H2O and imidazole with variation of the zinc-to-imidazole ...
The influence of storage and heat treatment on a magnesium-based implant material: An in vitro and in vivo study

Bracht, Katja; Angrisani, Nina; Seitz, Jan-Marten; Eifler, Rainer; Weizbauer, Andreas; Reifenrath, Janin (London : BioMed Central Ltd., 2015)

Background: Magnesium alloys are recommended as a potential material for osteosynthesis. It is known that storage-induced property modifications can occur in materials like aluminum. Thus the aim of this study was to analyze ...
Klimt artwork: red-pigment material investigation by backscattering Fe-57 Mossbauer spectroscopy, SEM and p-XRF

Lehmann, R.; Wengerowsky, D.; Schmidt, H. J.; Kumar, M.; Niebura, A.; Costa, B. F. O.; Dencker, F.; Klingelhoefer, G.; Sindelar, R.; Renz, F. (Abingdon : Taylor and Francis Ltd., 2017)

Material tests were performed on a rediscovered Klimt-artwork "Trompetender Putto". We performed studies on the red colored spots, mainly taken from non-restored parts. MIMOS II Fe-57 Mossbauer spectroscopy (novelty in ...
MXene molecular sieving membranes for highly efficient gas separation

Ding, Li; Wei, Yanying; Li, Libo; Zhang, Tao; Wang, Haihui; Xue, Jian; Ding, Liang-Xin; Wang, Suqing; Caro, Jürgen; Gogotsi, Yury (London : Nature Publishing Group, 2018)

Molecular sieving membranes with sufficient and uniform nanochannels that break the permeability-selectivity trade-off are desirable for energy-efficient gas separation, and the arising two-dimensional (2D) materials provide ...
Osteogenic differentiation of human mesenchymal stem cells in 3-D Zr-Si organic-inorganic scaffolds produced by two-photon polymerization technique

Koroleva, Anastasia; Deiwick, Andrea; Nguyen, Alexander; Schlie-Wolter, Sabrina; Narayan, Roger; Timashev, Peter; Popov, Vladimir; Bagratashvili, Victor N.; Chichkov, Boris (San Francisco, CA : Public Library of Science, 2015)

Two-photon polymerization (2PP) is applied for the fabrication of 3-D Zr-Si scaffolds for bone tissue engineering. Zr-Si scaffolds with 150, 200, and 250 μm pore sizes are seeded with human bone marrow stem cells (hBMSCs) ...
Outer electrospun polycaprolactone shell induces massive foreign body reaction and impairs axonal regeneration through 3D multichannel chitosan nerve guides

Duda, Sven; Dreyer, Lutz; Behrens, Peter; Wienecke, Soenke; Chakradeo, Tanmay; Glasmacher, Birgit; Haastert-Talini, Kirsten (New York, NY : Hindawi Publishing Corporation, 2014)

We report on the performance of composite nerve grafts with an inner 3D multichannel porous chitosan core and an outer electrospun polycaprolactone shell. The inner chitosan core provided multiple guidance channels for ...
