Using an animal model, investigators find that Mitomycin C, a common chemotherapy agent, offers limited benefit in reducing keloid or hypertrophic scars.
The tendency for extreme scarring is one reason many African Americans avoid plastic surgery and other surgical incisions. Though surgeons continue to develop less invasive techniques that minimize scarring, other options are needed to help these individuals who are prone to developing keloid scars.
Keloid scars are caused by an overproduction of fibroblasts, the structure on which cells build tissue to heal a wound. The fibroblasts continue to multiply after the wound is filled in and become a raised scar that grows beyond the original wound or point of incision. Dark skinned individuals tend to form keloids more readily than lighter skinned individuals. Hypertrophic scars are more common and occur in all racial groups. They appear raised but stay within the confines of the initial wound or point of incision. Both types of scars can occur through skin injuries such as surgical incisions, traumatic wounds, vaccination sites, burns, chickenpox, acne, or even minor scratches.

World first experiments on sensor that may revolutionise everything from medical devices to unmanned vehicles
The new sensor - capable of detecting vibrations of living cells - may revolutionise everything from medical devices to unmanned vehicles.
Dead and alive at the same time? Researchers at the Max Planck Institute of Quantum Optics have implemented Erwin Schrödinger’s paradoxical gedanken experiment employing an entangled atom-light state.
In 1935 Erwin Schrödinger formulated a thought experiment designed to capture the paradoxical nature of quantum physics. The crucial element of this gedanken...
Cellulose obtained from wood has amazing material properties. Empa researchers are now equipping the biodegradable material with additional functionalities to produce implants for cartilage diseases using 3D printing.
It all starts with an ear. Empa researcher Michael Hausmann removes the object shaped like a human ear from the 3D printer and explains:
The phenomenon of so-called superlubricity is known, but so far the explanation at the atomic level has been missing: for example, how does extremely low friction occur in bearings? Researchers from the Fraunhofer Institutes IWM and IWS jointly deciphered a universal mechanism of superlubricity for certain diamond-like carbon layers in combination with organic lubricants. Based on this knowledge, it is now possible to formulate design rules for supra lubricating layer-lubricant combinations. The results are presented in an article in Nature Communications, volume 10.
One of the most important prerequisites for sustainable and environmentally friendly mobility is minimizing friction. Research and industry have been dedicated...
