#Cells press down to make wounds heal faster National University of Singapore rightoriginal Studyposted by Karen Loh-NUS on September 12 2014scientists have uncovered more details about how our bodies repair wounds.
One involves the"purse-string"mechanism where a ring of proteins forms at the edge of a wound
At the early stages traction forces point away from the wound which suggests wound closure is driven initially by cell crawling.
At later stages the team observed forces pointing toward the wound. The investigators discovered a new mechanism
The contractions enable the cells to close the wound by cooperatively pressing down on the underlying tissue thus quickening the healing.
#Drug combo heals wounds fast with less scarring Johns hopkins university rightoriginal Studyposted by Vanessa Mcmains-Johns Hopkins on August 28 2014doctors have stumbled onto a potential new use for two approved medications.
When used in combination they heal wounds more quickly with less scar tissue. In mice and rats injecting the two drugs in combination speeds the healing of surgical woundsâ#by about one-quarter
##The wound healing potential of the two drugs was discovered incidentally while the researchers were working to prevent rejection of liver transplants.
Focusing on just the wound healing##side effect##the scientists launched the rodent study to determine what the mechanism behind its therapeutic effects might be.
Additionally they found that the wounds in animals that received the drug combination healed with less scar tissue and regrew skinâ##s hair follicles.
which can run for years without needing to be wound manually. The new system works like this:
Its viscosity acidity and sugar content make it good at sealing wounds and it even contains small amounts of hydrogen peroxide.
but they did work wonders for 10 horses with persistent wounds. The bacteria were mixed with honey
and applied directly to the horses'wounds which had resisted other attempted remedies. The mixture healed all 10.
while scar-forming cells migrate to the site of a wound. But finding ways of guiding artificial materials within the body has proven more difficult.
which, when wound on a spool, retains a certain amount of curve as it unwound.
To train the material Holschuh first wound raw SMA fiber into extremely tight millimeter-diameter coils then heated the coils to 450 degrees Celsius to set them into an original or trained shape.
Sensing thrombinblood clotting is produced by a complex cascade of protein interactions culminating in the formation of fibrin a fibrous protein that seals wounds.
"Our material's combination of injectability, rapid mechanical recovery, physiological stability and the ability to promote coagulation result in a hemostat for treating incompressible wounds in out-of-hospital, emergency situations,
and his colleagues solidifies at the site of the wound and begins promoting coagulation in the targeted area.
of which are platelets the blood component that accumulates at the site of the wound to form the initial plug.
As they do so the platelets release chemicals that call other platelets to the site eventually plugging the wound.

#Use of Ultrasound to Promote Faster Healing of Wounds Sometimes discoveries in science are not about the development of new medical devices or drugs,
Researchers from University of Sheffield have used now ultrasound to reduce healing times of diabetic wounds by 30%.
%The study, published in the Journal of Investigative Dermatology, describes the use of ultrasonic waves to promote wound healing cells called fibroblasts to migrate into the wound through mechanical stimulation.
and delayed wound healing of diabetic and elderly patients. sing ultrasound wakes up the cells
this technique for accelerated wound healing is expected to be in broad clinical use in the next 3-4 years.
Treatment of diabetic and aged mice recruits fibroblasts to the wound bed and reduces healing times by 30,
but applying these chemicals to the surface of wounds has its limits. To best stem blood loss, those chemicals need to be able to find their way deep into a wound.
There may now be a solution, however, and it comes in the unlikely form of fizz, reports Wired.
propelling them deep into a wound as they pop. The new concoction is composed of powdered marble, tranexamic acid
Water from the blood is the catalysis that sets it fizzing. f you can get the particles in the general area of the wound,
all the way to the damaged internal blood vessels feeding the wound. By clotting so deep into the lesion, the clot was shown to be more stable.
While chemicals do get deeper into the wound, they pop off in every other direction too. Eventually researchers hope to make the delivery process more efficient,

a novel microtubule-based regulator of wound healing"."e envision that our nanoparticle therapy could be used to speed the healing of all sorts of wounds,
including everyday cuts and burns, surgical incisions, and chronic skin ulcers, which are a particular problem in the elderly
Dr. Sharp and his colleagues had discovered earlier that an enzyme called fidgetin-like 2 (FL2) puts the brakes on skin cells as they migrate towards wounds to heal them.
and applied the nanoparticles to wounds on mice. The treated wounds healed much faster than untreated wounds.
FL2 belongs to the fidgetin family of enzymes, which play varying roles in cellular development and function.
When those cells were placed on a standard wound assay (for measuring properties like cell migration and proliferation),
Dr. Sharp and project co-leader Joshua Nosanchuk, M d.,professor of medicine at Einstein and attending physician, infectious diseases at Montefiore Medical center, developed a wound-healing therapy that uses
In both cases, the wounds closed more than twice as fast as in untreated controls. ot only did the cells move into the wounds faster,

Hard-to-treat wounds near the anus afflict around 50,000 people in Europe every year. In a phase III trial, a treatment developed by Tigenix in Belgium improved the chances of healing such wounds by 50 per cent and apparently with no adverse side effects.
The therapy uses stem cells derived from donated liposuction tissue which have extremely low levels of the proteins that trigger immune reactions,
