Speciation is a multifaceted process that involves numerous aspects of the biological sciences and occurs for multiple reasons. Ecology plays a major role, including both abiotic and biotic factors. Whether populations experience similar or divergent ecological environments, they often adapt to local conditions through divergence in biomechanical traits. We investigate the role of biomechanics ...

The objective of this review is to provide basic information pertaining to biomechanical aspects of bone as they relate to tissue engineering. The review is written for the general tissue engineering reader, who may not have a biomechanical engineering background. To this end, biomechanical characteristics and properties of normal and repair cortical and cancellous bone are presented. Also, thi...

Background: The trapeziometacarpal joint (TMCJ) is inherently unstable, relying on ligament restraint to preventsubluxation. Subluxation of the thumb in a dorsoradial direction is often observed in clinical practice, either after acuteligament injury or more commonly with osteoarthritis (OA). This subluxation follows loss of function of trapeziometacarpalligaments that stabilise this joint, res...

The aim of this study was to compare the efficacy of honey bee venom (BV) and royal jelly (RJ) alongside chitosan scaffold (CS) in improving radius bone defect in rats. A total of 60 full thickness radial bone defects with a length of 5 mm were created in 60 male Wistar rats. Six healthy radial bones (3 rats) were also assigned as normal control for biom...

background: plasterers are at risk of musculoskeletal disorders (msds) due to the nature of their occupation and ergonomic factors. the purpose of this study was to evaluate the biomechanical risk factors for msds among plasterers. materials and methods: in this descriptive study, 70 plasterers from neyshabur, iran, were studied in 2014. the nordic musculoskeletal questionnaire (nmq) was used t...

objective: to assess the effects of platelet rich plasma (prp) with chitosan biodegradable film on full thickness wound healing in rat. methods: this was an experimental study being performed in 2015 during a 4-month period. twenty-four male white wistar rats were divided into four groups of 12 rats each, randomly: control group (sham) with creation of wounds and no treatment, prp group with cr...

Magnesium-based interference screws may be an alternative in anterior/posterior cruciate ligament reconstruction. The well-known osteoconductive effects of biodegradable magnesium alloys may be useful. It was the purpose of this study to evaluate the biomechanical properties of a magnesium based interference screw and compare it to a standard implant. A MgYREZr-alloy interference screw and a st...
