    Characterization of Cortical Bone Thickness Changes in the Human Ribs with Age and Sex Sarah K. Lynch, Ashley A. Weaver, Samantha L. Schoell, Joel D. Stitzel Wake Forest University, Winston-Salem, NC Abstract This study characterized age and sex-related changes in rib cortical thickness to study the effect on thoracic injury risk.   Use of a gambling task and a functional magnetic resonance imaging (fMRI) scanner shows that human subjects' choices can be characterized by a computationally well regarded strategy for addressing Cited by:

The effects of cyclooxygenase (COX) inhibition following the reconstruction of the anterior cruciate ligament remain unclear. We examined the effects of selective COX-2 and nonselective COX inhibition on bone-tendon integration in an in vitro model.

Bone cutting is a well know procedure in orthopedics. Large cutting force causes overstressing of the bone which may result in trauma.

Control penetration of the cutting tool into bone tissue is important to avoid unnecessary damage to the bone tissue. The purpose of this study was to measure and predict cutting force using experiments and Finite Element (FE) analysis when a Author: Khurshid Alam, Riaz Muhammad, Vadim Silberschmidt.

Quantification of Human Cortical Bone Bound and Free Water in Vivo with Ultrashort Echo Time MR Imaging: A Model-based by: The human sample was sourced from the Robert J. Terry Collection, housed at the National Museum of Natural History in Washington, DC, USA.

This collection was used because there are known biological data for these remains, which was important to control for as previous research has shown that factors such as age and sex may affect cortical bone thickness.Cited by: 5.

The key feature of the approach is the ability to quantify variation in the SOS, measured in meters per second (m/s) propagated in cortical bone, as caused by changes in the collection of bone. Electrical stimulation is a promising approach to enhance bone regeneration while having potential to inhibit bacterial growth.

To investigate effects of alternating electric field stimulation on both human osteoblasts and bacteria, a novel in vitro system was designed. Electric field distribution was simulated numerically and proved by experimental by: 5.

Bone samples were procured from 8 adults aged between 17 and 67 years, without sign of bone disease, from 4 children newborn and 7, 8 and 12 years at autopsy, and 2 from an older subject with necrosis of the head of the femur.
