14/01/2019There are many times when our cells need to move. Mobile cells guide our body's formation (embryonic development). Immune cells roam to capture unwanted intruders. And healing cells (fibroblasts) migrate to mend wounds. But not all movement is desirable: Tumors are most dangerous when cancer cells gain the ability to travel throughout the body (metastasis).
04/01/2019Skin has a remarkable ability to heal itself. But in some cases, wounds heal very slowly or not at all, putting a person at risk for chronic pain, infection and scarring. Now, researchers have developed a self-powered bandage that generates an electric field over an injury, dramatically reducing the healing time for skin wounds in rats. They report their results in ACS Nano.
17/12/2018Collagen is the fundamental building block of muscles, tissues, tendons, and ligaments in mammals. It is also widely used in reconstructive and cosmetic surgery. Although scientists have a good understanding about how it behaves at the tissue-level, some key mechanical properties of collagen at the nanoscale still remain elusive.
12/12/2018A new computational model developed by researchers from The City College of New York and Yale gives a clearer picture of the structure and mechanics of soft, shape-changing cells that could provide a better understanding of cancerous tumor growth, wound healing, and embryonic development.
10/12/2018A team of surgeons from the Perelman School of Medicine at the University of Pennsylvania are the first in the world to use a surgical robot to assist with a bilateral free flap breast reconstruction - a procedure in which tissue is taken from the lower abdomen and used to rebuild the breast. The robot allows surgeons to make a much smaller incision into the abdominal wall muscles.
03/12/2018Breast cancer survivors who used a smartphone app created at Houston Methodist consistently lost weight, largely due to daily, real-time interactions with their health care team via the mobile app. Few clinically-tested mobile apps exist today with clear measurable goals to support continued care of cancer survivors and patients.
21/11/2018Researchers at the University of New Hampshire have created an easy-to-make, low-cost injectable hydrogel that could help wounds heal faster, especially for patients with compromised health issues.
08/11/2018A new flexible sensor developed by engineers at the University of California, Berkeley, can map blood-oxygen levels over large areas of skin, tissue and organs, potentially giving doctors a new way to monitor healing wounds in real time.
01/06/2016Until now, plasma, the fourth state of matter,was consideredfascinatingonly to astrophysicists and science fiction fans. But at this point, it also attracts the interest of medicine because plasma can have many uses in this field. In the future, plasma sterilization could become an important component of hospital hygiene-provided that the right device is being used.
01/05/2016Antibody-coated, drug-eluting stents (AB-DES) feature an exterior coated with immunosuppressant drugs and an interior that is coated with antibodies to accelerate the adhesion of endothelial cells. In theory, this makes it possible to shorten the duration of therapy with blood thinners, which can mean relief for patients from an already difficult situation.
01/02/2016Sometimes, soft tissue in our body needs to be replaced after surgery or an injury. But surgeons are not always able to take tissue from other body parts as a replacement. Then, they need to use implants. The production of soft implants that can constantly endure load and stress like our own tissue is a big challenge for research. Melt electrospinning writing can be a solution.
03/11/2014The treatment of chronic wounds is extremely problematic. Chronic wounds can take months or years to heal and some even never heal resulting in over 100.000 amputations taking place annually in the US alone. A new technology from Iceland, that is based on fish skin and is already used clinically, allows for improved healing of chronic and burn wounds.
01/07/2014Large burns require skin grafting. Surgeons remove split-thickness skin grafts and apply them to the injured areas. Now skin that has been made in a laboratory is meant to help in covering burns as well as chronic wounds and thus promote the healing process. Researchers in Zurich have been working on this for more than 13 years.
