Healing

Protein from silkworm cocoons has been used to create strong yet biodegradable bone fixati...

Silk is an amazingly strong material, yet it also harmlessly biodegrades when left in the body. This has led to its use in experimental brain implants, heart patches, and even bio-electronics. According to a new study conducted by scientists at Tufts University School of Engineering and Beth Israel Deaconess Medical Center, it may now also find use in the production of better plates and screws used for securing broken bones.  Read More

Help could be on the way for people who don't have enough bone to support dental implants, who are missing bone due to a birth defect, or who have suffered bone-damaging injuries. Scientists at the University of Iowa have created an implantable collagen patch seeded with particles containing synthetic DNA, that instructs the patient's own cells to produce the protein that leads to bone growth.  Read More

Anyone who has left youth behind them knows that bumps and scrapes don't heal as fast as they used to. But that could change with researchers at the Stem Cell Program at Boston Children's Hospital finding a way to regrow hair, cartilage, bone, skin and other soft tissues in a mouse by reactivating a dormant gene called Lin28a. The discovery could lead to new treatments that provide adults with the regenerative powers they possessed when very young.  Read More

One of the prototype ulcer-healing patches

Venous ulcers are nasty things, often found on the lower extremities of elderly or inactive people. They occur when high blood pressure causes the skin adjacent to the affected veins to break down, leaving open wounds that take months or even years to heal. Standard treatments include compression bandages, infection control and standard wound dressings, although these approaches don’t work in all cases. Now, however, scientists are getting good results using band-aid-like patches that emit ultrasound into the ulcers.  Read More

A material currently in development works in the same fashion as a scab, to accelerate the...

While you may think that standard bandages already serve as sort-of artificial scabs, the fact is that they mainly just compress and protect the wound – a scab, on the other hand, actually helps it heal. Now, however, scientists are working on a wound dressing that promotes healing in the same fashion as a scab.  Read More

The new infection-indicating dressing on a healthy skin sample (R) and on an infected skin...

Serious burns can lead to infection and potentially fatal toxic shock syndrome (TSS). Once an infection sets in, it is vital to begin treatment quickly to avoid or minimize a transition to TSS. The problem is, removing dressings to check for infection can be painful, slow the healing process and increase the chance of scarring. A prototype dressing developed by chemists at the University of Bath in the UK alerts doctors to the first signs of infection by glowing under ultraviolet (UV) light.  Read More

New technology could facilitate the healing of damaged nerves  (Image: Shutterstock)

When a nerve in the peripheral nervous system is torn or severed, it can take a long time to regenerate – if it does so at all. Depending on the location of the injury, it can leave the affected part of the patient’s body numb and/or paralyzed for years, or even for the rest of their life. Now, however, scientists from Israel’s Tel Aviv University have created a gel and an implant that they claim could vastly aid in the healing of damaged nerves.  Read More

Only a few bacteria are left over, after the hydrogel was used to destroy a solid bacteria...

Whether it’s in hospitals, restaurant kitchens or our homes, harmful bacteria such as E.coli are a constant concern. Making matters worse is the fact that such bacteria are increasingly developing a resistance to antibiotics. This has led to a number of research projects, which have utilized things such as blue light, cold plasma and ozone to kill germs. One of the latest non-antibiotic bacteria-slayers is a hydrogel developed by IBM Research and the Institute of Bioengineering and Nanotechnology in Singapore.  Read More

Researchers have found that oxygen-containing free radicals aid rather than harm cell rege...

Researchers at the University of Manchester have found that Reactive Oxygen Species (ROS) – oxygen-containing free radicals that are commonly believed to be harmful to cells – actually play a vital role in the regeneration of the tails of tadpoles. The finding could have profound implications for the healing and regeneration of human tissue.  Read More

Scientists have used polymer implants to grow new adult brain tissue (Image: Shutterstock)

Using implants made from porous biocompatible materials, scientists have recently been successful in regrowing things such as teeth, tendons and heart tissue, plus bone and cartilage. The materials act as a sort of nanoscale three-dimensional scaffolding, to which lab-cultivated cells can be added, or that the recipient’s own cells can colonize. Now, a Spanish research team has used the same principle to grow new brain tissue – the technique could ultimately be used to treat victims of brain injuries or strokes.  Read More
