Implant surface features as key role on cell behavior
It has been recognized that physical and chemical properties of biomaterial surfaces mediate the quality of extracellular matrix (ECM) that may affect cell behaviors. In nature, ECM is a heterogeneous three-dimensional ...
Lock-and-key effect in the surface diffusion of large organic molecules probed by STM
(Nature Publishing GroupLondonInglaterra, 2004)
The effect of controlled microrobotized blasting on implant surface texturing and early osseointegration
(Sage Publications Ltd, 2016-02-01)
Surface topography modifications have become a key strategy for hastening the host-to-implant response to implantable materials. The present study evaluated the effect of three different carefully controlled surface texture ...
Two new species of Pergalumna (Acari, Oribatida, Galumnidae) from Costa Rica, including a key to all species of the genus from the Neotropical region
Two new species of oribatid mites of the genus Pergalumna (Oribatida, Galumnidae), P. elongatiporosa sp. n. and P. striatiprodorsum sp. n., are described from leaf litter of a secondary forest in Costa Rica. Pergalumna ...
The Role of MicroRNAs in the Osseointegration Process
(Quintessence Publishing Co Inc, 2019-03-01)
Regulation of cellular function is key to bone formation at endosseous implant surfaces. Osseointegration was discovered prior to the discovery of genetic regulation of osteoinduction or characterization of mesenchymal ...
Dielectric exchange: The key repulsive or attractive transient forces between atomic force microscope tips and charged surfaces
(Amer Inst PhysicsWoodburyEUA, 1999)
Effects of surface stability on the morphological transformation of metals and metal oxides as investigated by first-principles calculations
Morphology is a key property of materials. Owing to their precise structure and morphology, crystals and nanocrystals provide excellent model systems for joint experimental and theoretical investigations into surface-related ...
Experiments on generation of surface waves by an underwater moving bottom
(The Royal Society, 2015)
We report laboratory experiments on surface waves generated in a uniform fluid layer whose bottom undergoes an upward motion. Simultaneous measurements of the free-surface deformation and the fluid velocity field are focused ...
Importance of surface chemistry in bacterial adhesion to metals and biocorrosion
(De Gruyter, 2004-08-01)
The aim of this work is to emphasize the central role of surface chemistry as a determining factor during the process of bacterial adhesion and biofilm formation on metals. Experimental results showing the influence of the ...
