The origin of marrow regeneration after mechanical depletion was reinvestigated in mouse chimeras. The results were compatible with the local origin of stem cells from remnants of incompletely removed marrow, but not with their origin from a common precursor of both bone and hemopoietic cell lines. In transplanted femurs depleted by a modified technique of in vivo evacuation of marrow, hemopoie...

Effects of modifying the plate-bone interface with Silastic@were tested. The experimental plate, i.e.,aconventionalplate with aSilastic@backing wascompared with the standard plate. In vitro four-point bending tests showed similar strain per load behavior in the experimental and standard plate models. In vitro plate-bone contact was greater and interface pressure was lower for the experimental a...

Differences in microscopic structure of the femur between 2 month-old transgenic rabbits with hFVIII gene and the non-transgenic ones were investigated. Qualitative and quantitative histological characteristics of compact bone microstructure were evaluated. We observed the presence of fibrolamellar bone tissue only in transgenic rabbits. Measured values for area, perimeter, maximum and minimum ...

BACKGROUND While gross morphological changes in the skeleton between males and females are well know, differences between sexes in the histomorphology are less known. It is important to have knowledge on the bone structure of rabbits, as this is a widely used species in biomedical research. A study was performed to evaluate the association between sex and the compact bone morphology of the femo...

Introduction A correct diagnosis and optimal treatment planning is essential for success in implant dentistry. Proper diagnosis of bone quality is an important part of the diagnostic procedure. Objective The purpose of this study was to correlate the tactile sense of the surgeon in the assessment of bone density to the histomorphometric analysis of bone quality. Methods In this study, 56 bo...
