Shear bond strength and debonding characteristics of a new premixed self-etching with a reference total-etch adhesive
Comparative genomics and host resistance against infectious diseases.
The large size and complexity of the human genome have limited the identification and functional characterization of components of the innate immune system that play a critical role in front-line defense against invading microorganisms. However, advances in genome analysis (including the development of comprehensive sets of informative genetic markers, improved physical mapping methods, and novel techniques for transcript identification) have reduced the obstacles to discovery of novel host resistance genes. Study of the genomic organization and content of widely divergent vertebrate species has shown a remarkable degree of evolutionary conservation and enables meaningful cross-species comparison and analysis of newly discovered genes. Application of comparative genomics to host resistance will rapidly expand our understanding of human immune defense by facilitating the translation of knowledge acquired through the study of model organisms. We review the rationale and resources for comparative genomic analysis and describe three examples of host resistance genes successfully identified by this approach
Multiple functions of gingival and mucoperiosteal fibroblasts in oral wound healing and repair
The masticatory system under varying functional load. Part 1: structural adaptation of rabbit jaw muscles to reduced masticatory load
Comparison of scanning times for different dental cast materials using an intraoral scanner
Characterization and quantification of dissolved organic carbon releases from suspended and sedimented leaf fragments and of residual particulate organic matter
Assessment of phantom dosimetry and image quality of i-CAT FLX cone-beam computed tomography
Increasing use of cone-beam computed tomography in orthodontics has been coupled with heightened concern with the long-term risks of x-ray exposure in orthodontic populations. An industry response to this has been to offer low-exposure alternative scanning options in newer cone-beam computed tomography models
