The relationship between bone mineral density and bone strength has been investigated as a ubiquitous property of bone. This study utilized 22 isolated vertebral body preparations which had their volumetric bone mineral density quantified and their compressive mechanics measured. Cadaveric baboon ninth thoracic vertebral body samples were investigated which ranged in age from 1 to 30 years and ...

BACKGROUND AND AIMS Exotic herbivores that lack a coevolutionary history with their host plants can benefit from poorly adapted host defences, potentially leading to rapid population growth of the herbivore and severe damage to its plant hosts. The hemlock woolly adelgid (Adelges tsugae) is an exotic hemipteran that feeds on the long-lived conifer eastern hemlock (Tsuga canadensis), causing rap...

BACKGROUND Robust techniques for characterizing the biomechanical properties of mouse pulmonary arteries will permit exciting gene-level hypotheses regarding pulmonary vascular disease to be tested in genetically engineered animals. In this paper, we present the first measurements of the biomechanical properties of mouse pulmonary arteries. METHOD OF APPROACH In an isolated vessel perfusion s...

There are many unanswered questions about giant cell tumor (GCT) treatment and not enough attention is paid to the biomechanics of the current treatment methods. Treatment methods have not changed much, and the best method remains controversial to some degree, due to the lack of adequate clinical and biomechanical investigations. Biomechanical tests, including in vitro mechanical experiments co...

BACKGROUND Numerous surgical techniques have been described to address injuries to the coracoclavicular ligaments. PURPOSE To compare the biomechanical properties of tendon graft reconstructions with those of the native coracoclavicular ligaments and various other repair methods. STUDY DESIGN Controlled laboratory study. METHODS Eleven fresh-frozen human cadaveric shoulders were tensile t...

Resistance training has been used for the purpose of improving muscular strength, power and endurance, and rehabilitation. It is important to consider the individual biomechanical characteristics in training and rehabilitation. Conventional commercial resistance training machines for resistance training have limitations on adapting the workout person’s biomechanical characteristics because they...

abstract objective: the aim of this study was to evaluate the efficacy of antibiotic-loaded bone cement in controlling local infection and in regard to its physical characteristics, elastic modulus, and tensile strength in-vitro. methods: acrylic bone cement, based on polymethylmethacrylate (pmma) was mixed with the powder form of three antibiotics, i.e., gentamicin, tobramycin, and cefuroxime ...

Industrial work is a very active sector in the economy of countries; an important part of people's work is done using the upper extremities. The purpose of this project is to characterize the effect of upper extremity work, analyze its relationship with the hand strength and the presence of fatigue and develop a model with the ability to estimate recovery times for the shoulder using variables ...
