2018-04-04

Staphylococcus aureus (S. aureus) is the main source of osteomyelitis in adults. The end-result of untreated osteomyelitis is bone necrosis and distraction of bone structure. While bone tissue can heal and remodel its structure to ameliorate its mechanical pr...

Tribological evaluation of biomedical polycarbonate urethanes against articular cartilage

10.1016/j.jmbbm.2018.04.001

2018-04-03

This research investigated the in-vitro wear and friction performance of polycarbonate urethane (PCU) 80 A as they interact with articular cartilage, using a customised multidirectional pin-on-plate tester. Condyles were articulated against PCU 80 A discs (Bi...

Mechanical alterations of the bone-cartilage unit in a rabbit model of early osteoarthrosis

2018-04-03

Objective The purpose of this study was to assess mechanical properties along with microstructural modifications of the hyaline cartilage (HC), calcified cartilage (CC) and cortical plate (Ct.Pt), in an anterior cruciate ligament transection (ACLT) model. Med...

Swelling of Fiber-Reinforced Soft Tissues is Affected by Fiber Orientation, Fiber Stiffness, and Lamella Structure

10.1016/j.jmbbm.2018.03.039

2018-04-03

Native and engineered fiber-reinforced tissues are composites comprised of stiff collagen fibers embedded within an extrafibrillar matrix that is capable of swelling by absorbing water molecules. Tissue swelling is important for understanding stress distribut...

2018-04-03

This is the first study to simultaneously measure material properties in tension, compression, nanoindentation as well as microstructure (crystallinity and lamellar level properties) across a wide variety of clinically relevant ultra-high molecular weight pol...

Fibroblast populated collagen lattices exhibit opposite biophysical conditions by fibrin or hyaluronic acid supplementation ☆

10.1016/j.jmbbm.2018.03.042

2018-03-31

Fibrin and hyaluronic acid are important components of the provisional wound matrix. Through interactions with fibroblasts, they provide biophysical cues that regulate the viscoelastic properties of the extracellular matrix. To understand the roles of fibrin ...

Effect of multiscale structural parameters on the mechanical properties of rice stems

2018-03-31

The objective of this study was to investigate the relation between the structural parameters and the mechanical properties of rice stem at different scales. Tensile modulus and bending properties of different kinds of rice stems were measured through tensile...

GALLIUM INCORPORATION INTO PHOSPHATE BASED GLASSES: BULK AND THIN FILM PROPERTIES

10.1016/j.jmbbm.2018.03.041

2018-03-30

The osteogenic ions Ca2+, P5+, Mg2+, and antimicrobial ion Ga3+ were homogenously dispersed into a 1.45 μm thick phosphate glass coating by plasma assisted sputtering onto CP grade titanium. The objective was to deliver therapeutic ions in orthopedic/dental i...

Viscoelastic Characterization of Woven Dacron for Aortic Grafts by using Direction-Dependent Quasi-Linear Viscoelasticity

10.1016/j.jmbbm.2018.03.038

2018-03-30

In case of direction-dependent viscoelasticity, a simplified formulation of the three-dimensional quasi-linear viscoelasticity has been obtained manipulating the original Fung equation. The experimental characterization of the static hyperelastic behaviour, t...

Analyzing nature's protective design: the glyptodont body armor

10.1016/j.jmbbm.2018.03.037

2018-03-29

Many animal species evolved some form of body armor, such as scales of fish and bony plates or osteoderms of reptiles. Although a protective function is often taken for granted, recent studies show that that body armor might comprise multiple functionalities ...
