Modified maggots fast-track wound healing

It might be a little hard to stomach, but using maggots to clean up wounds is a technique that has been in use for centuries. By selectively devouring dead flesh and leaving healthy tissue intact, these loathsome larvae have offered a cheap way of treating wounds, but not necessarily a quicker one. Now scientists are looking to hasten the healing process by genetically modifying maggots to produce a human growth factor while they go about their business.Read More

Infection-fighting bandages may help treat serious burns

When a burn wound is healing, it's usually highly susceptible to infection, and bandages often make the situation worse, acting as breeding grounds for harmful microbes. A new bandage developed by researchers at the Swiss Federal Institute of Technology in Luassane (EPFL) could improve the healing process considerably, accelerating the healing process, while stopping bacteria multiplying.Read More

New hydrogel aids skin regeneration to improve wound healing

Healing chronic skin wounds can be difficult, particularly when they span large areas, or when healing is complicated by health problems such as a lack of mobility. A team of researchers from the University of California, Los Angeles (UCLA) has worked to improve the process, creating a more effective method of regeneration through use of a new material that creates a porous scaffold, allowing wounds to heal more effectively.Read More

3D-printed guide aids in complex nerve regeneration

Complex nerve injuries are a challenging problem for the medical fraternity, as their reattachment and regrowth is a fraught and delicate process that is very rarely successful. Overcoming these difficulties, however, would mean that a cure for debilitating conditions like paraplegia, quadriplegia and other forms of paralysis may one day be found. In this vein, US researchers have created the first-ever 3D printed guide specifically designed to assist in the regrowth of the sensory and motor functions of complex nerves.Read More

New material helps diabetic wounds heal faster

Because they often have weakened immune systems and/or blood flow restrictions, diabetics run a heightened risk of serious infection from even the smallest of open wounds. That's why a team of scientists from Egypt's Alexandria University have developed a means of getting those wounds to heal faster – silver-impregnated dressings.Read More

Ultrasound cuts healing time of chronic wounds by 30 percent

Further to the mental anguish, a lot of time in a hospital bed can bring about some agonizing physical discomfort. This is most commonly brought about by skin ulcers and bedsores, which threaten to evolve into dangerous and potentially deadly infections if left untreated. But a British research team has happened upon a technique that promises to cut the healing time of these and other chronic wounds by around a third, using simple low-intensity ultrasounds.Read More

Elastic, wound-healing hydrogel activated by light

Hydrogels have huge potential in the field of biomedicine, but aren't without their shortcomings in their existing form. These tiny polypeptide chains are championed for their many possible applications. Indeed, in the last few years alone we've seen advances that suggest they could find use in generating new heart tissue, fighting off superbugs and the controlled release of anti-inflammatory drugs. But researchers have now developed a hydrogel that mimics the elasticity of human tissue and can be activated by exposure to light, claiming it could offer safer means of repairing wounded tissue.Read More
