Sol-gel technology is increasingly being used in coatings for corrosion protection and adhesion improvement. So far, the self-healing concept in sol-gel coatings has only been approached from extrinsic healing perspective (i.e. use of nano and micro carriers of corrosion inhibitors) [1]. Despite the benefits of this approach, the damaged area remains open to ambient environment. The implementat...

The current trend in the non-operative treatment of femoral shaft fractures is away from prolonged traction and towards early ambulation. The cast brace treatment involves external support to the limb in such a way that maximal use can occur during healing. Early ambulation, while a fracture is healing, provides an environment for complete bone healing as well as allowing joint movement so that...

In this paper we address the management of sensor faults in an intelligent environment. Our proposed approach aims to introduce self-healing as a method of fault management. This approach is based on the use of adaptive finite state machine automata which handle suspicious sensor behavior. These state machines communicate with a mobile robot which investigates the error states detected through ...

Cancer represents a unique state whereby the body's healing system fails to eliminate cells with damaged or altered DNA. This allows these cells to escape the normal regulatory signals leading to uncontrolled cell growth. While most auto-immune diseases represent a failure of the healing system from an over-active immune system, cancer represents the extreme opposite, whereby the immune system ...

Fracture healing is a complex process in which mechanical forces are essential for the regeneration of bone tissue. Mechanical loading can induce osteogenesis through the process of mechanotransduction. Current data on how mechanical loading stimulates fracture healing in weight-bearing long bones are presented. The role of mechanosensors, loading-induced interstitial fluid flow, streaming pote...

We treated fifty-one cases of fracture of the shaft of the humerus with a functional method of treatment consisting of a plastic sleeve, individually molded or prefabricated. It maintained good alignment of the fragments and permitted rapid and uninterrupted osteogenesis. The early introduction of functional activity to the entire extremity appears to provide a desirable physiological environme...

The ultimate goal in the management of burn wounds is to obtain physiological closure in the shortest period of time. Traditional burn wound management involves cleansing, debridement and provision of a moist environment to encourage the process of natural healing. Hence, an ideal dressing material has to maintain a moist environment, act as a bacterial barrier, and as a medium for free exchang...

Synthetic materials that are capable of autonomous healing upon damage are being developed at a rapid pace because of their many potential applications. Despite these advancements, achieving self-healing in permanently cross-linked hydrogels has remained elusive because of the presence of water and irreversible cross-links. Here, we demonstrate that permanently cross-linked hydrogels can be eng...

The vacuum-assisted closure (VAC) technique is a relatively recent procedure that consists of administering negative pressure on the wound in conjunction with closed environment decreases edema, facilitating vascularization, oxygenation and healing. In addition, it promotes formation granulation tissue. We present case an 18-year-old woman bloody anterior side left thigh. Surgical washing thera...

Wound healing is a complex homeostatic response to injury that engages numerous cellular activities, processes, and cell-to-cell interactions. The complement system, an intricate network of proteins with important roles in immune surveillance and homeostasis, has been implicated in many physiological processes; however, its role in wound healing remains largely unexplored. In this study, we emp...
