The human nervous system is a complex structure that sends electrical signals from the brain to the rest of the body, enabling us to move and think. Unfortunately, when brain cells are damaged by trauma or disease they don't automatically regenerate. This can lead to permanent disability.
Scientists have developed a ground-breaking technology that can print electronics and cells directly onto skin and could be used to provide chemical sensors for soldiers in combat zones and new treatments for skin disorders.
One of the most vexing problems with spinal cord injuries is that the human body does not rebuild nerves once they have been damaged. Other animals, on the other hand, seem to have no problem repairing broken neurons.
One of the most frustrating and debilitating complications of diabetes is the development of wounds on the foot or lower leg. Once they form, they can persist for months, leading to painful and dangerous infections.
Kyle Quinn, assistant professor of biomedical engineering at the University of Arkansas, has published a review highlighting recent advances in autofluorescence imaging and discussing its role in evaluating cell metabolism.
Researchers from RMIT University have developed a new artificial enzyme that uses light to kill bacteria.
A penetrating injury from shrapnel is a serious obstacle in overcoming battlefield wounds that can ultimately lead to death.Given the high mortality rates due to hemorrhaging, there is an unmet need to quickly self-administer materials that prevent fatality due to excessive blood loss.
Patients traveling to developing countries for plastic surgery procedures may experience severe complications—requiring extensive and costly treatment after they return to the United States, reports a study in the April issue of Plastic and Reconstructive Surgery, the official medical journal of the American Society of Plastic Surgeons.
