The processes of normal and abnormal fracture healing and the various factors affecting them have been widely studied since the days of Galen and Hippocrates. Rabbit tibial fracture is a major fracture model. The fracturing methods used in this model

The mechanical properties of bone obey Newton’s and Hook’s laws of mechanics. The mechanical behavior of bone in normal physiological situations is similar to that of an elastic material. Mechanical testing of bone is involved in most bone-relate

Aim: Gap-junctional connexin43 (Cx43) has roles in multiple aspects of skin wound healing – including scarring. The aim here was to study the effects of a cell-permeant peptide from the Cx43 carboxyl-terminus (CT) on scarring and regeneration follo

Centrifugal casting allows rapid biofabrication of tubular tissue constructs by suspending living cells in an in situ cross-linkable hydrogel. We hypothesize that introduction of laser-machined micropores into a decellularized natural scaffold will f

Purpose The purpose of this study was to compare the volumetric cutting rates of 6 cylindrical-shaped single-patient-use and 2 cylindrical-shaped multiple-patient-use diamond burs using a machinable ceramic material. The degree of wear among burs fro

Many studies have shown enhanced bone apposition to implants coated with hydroxyapatite, but the optimum implant texture, especially in abnormal trabecular bone, is unclear. The purpose of this project was to evaluate the histological and mechanical

Brain acetylcholinesterase (AChE) inhibition was measured during 4-week and 4-day episodic exposures to chlorpyrifos. Organisms were exposed to a seawater (−) control, an acetone (+) control (0.1%), and 0.625, 1.25, 2.5, 5.0, and 10.0 μg of chlorp

Objectives. The aim of the present work was to establish a design procedure for fixed metal prostheses supported by osseointegrated implants in order to prevent permanent deformation and hence failure following loading. Previously, the cantilever cro

A method for rapid enumeration of S. epidermidis adhered to the surface of commercially pure titanium samples was developed using image analyzed epifluorescence microscopy. The method was used to determine the effects of different surface roughnesses
