Scientists from the Perm National Research Polytechnic University (PNRPU) conducted a study on skin samples for transplantation. This will help increase the efficiency of transplantation operations. The press service of the scientific institution told socialbites.ca about this.
According to WHO, burns are the third most common injury among other injuries. More than 800 thousand such cases are recorded in Russia every year.
In a new scientific project, Perm Polytechnic experts used donor skin tissue samples taken from the backs of patients after they died. The average thickness of the prepared pieces was 2.56 mm.
Tensile tests were performed using a universal mechanical testing machine.
“Several types of samples were tested against Langer lines. These are natural lines in the skin that reflect the direction of orientation of collagen fibers in the dermis. The “softest” parameters were tissue samples taken from the skin perpendicular to the Langer lines. A higher elastic modulus was shown in samples placed obliquely to such lines, the authors noted.
During the tests, it turned out that the stiffness of the leather when stretched parallel to the Langer lines was 3.5 times higher than when the samples were stretched in the transverse direction.
According to scientists, the results of the experiments will be key to the development of effective methods for the treatment of body tissues damaged by various injuries and diseases.
PNRPU explained that the data is also used to create new types and modifications of silicone materials for the production of prosthetics that meet the requirements of naturalness and functionality.
Russian scientists previously to create algae that can remove radioactive substances from the environment.
