OBJECTIVE Titanium oxide nanotube layers by anodization have excellent potential for dental implants because of good bone cell promotion. It is necessary to evaluate osteoblast behavior on different annealing temperature titania nanotubes for actual implant designs. MATERIALS AND METHODS  Scanning Electron Microscopy, X-Ray polycrystalline Diffractometer(More)
The study of large networks has attracted a lot of attention in recent years (cf. [1] to [41]). Networks play an important role in many fields, from the analysis of the World-Wide Web to social research (scientific collaborations, citation networks, ...) to the life sciences (ecological webs, regulatory, protein, metabolic networks, ...). Some statistical(More)
Here, the reliability of a recent approach to use parameterised linear programming for detecting community structures in network has been investigated. Using a one-parameter family of objective functions, a number of "perturbation experiments' document that our approach works rather well. A real-life network and a family of benchmark network are also(More)
OBJECTIVES To investigate behaviour and osteogenic cytokine expression of RAW264.7 macrophages grown on TiO2 nanotube layers. MATERIALS AND METHODS The murine macrophage cell line RAW 264.7 was cultured on TiO2 nanotubes of varying diameter; macrophage morphology was examined using scanning electron microscopy. Cell adhesion and viability were assessed(More)
Abstract In this note, we explore — by means of a specific case study — the potential of a new approach towards identifying gene functional modules in Gene-Ontology (or, for short, GO) networks, i.e., networks whose nodes are formed by the genes from a given collection of genes under consideration while two such nodes are connected by an edge if and only if(More)
