Electrospun Biomaterials in the Treatment and Prevention of Scars in Skin Wound Healing

Bommie F. Keloids and hypertrophic scars are thick, raised dermal scars, caused by derailing of the normal scarring process. Extensive research on such abnormal scarring has been done; however, these being refractory disorders specific to humans, it has been difficult to establish a universal animal model. A wide variety of animal models have been used. These include the athymic mouse, rats, rabbits, and pigs. Although these models have provided valuable insight into abnormal scarring, there is currently still no ideal model. This paper reviews the models that have been developed.

Electrospinning is a promising method for the rapid and cost-effective production of nanofibers from a wide variety of polymers given the high surface area morphology of these nanofibers, they make excellent wound dressings, and so have significant potential in the prevention and treatment of scars. Wound healing and the resulting scar formation are exceptionally well-characterized on a molecular and cellular level. Despite this, novel effective anti-scarring treatments which exploit this knowledge are still clinically absent. As the process of electrospinning can produce fibers from a variety of polymers, the treatment avenues for scars are vast, with therapeutic potential in choice of polymers, drug incorporation, and cell-seeded scaffolds. It is essential to show the new advances in this field; thus, this review will investigate the molecular processes of wound healing and scar tissue formation, the process of electrospinning, and examine how electrospun biomaterials can be utilized and adapted to wound repair in the hope of reducing scar tissue formation and conferring an enhanced tensile strength of the skin. Future directions of the research will explore potential novel electrospun treatments, such as gene therapies, as targets for enhanced tissue repair applications.

Unlocking the secrets of scar-free skin healing

Developed within the last few decades, microneedles MNs have only recently seen wide-scale use among the general population, especially in the area of cosmetics. With the FDA only starting to regulate microneedling devices and the many new microneedling products that enter the modern global market, it is of utmost importance to establish the safety profile and reasonable expectations of the microneedling practice and its products. Despite wide-scale implementation of MNs, we are likely only beginning to understand the potential of MNs as a medical and consumer product, and we should, therefore, be aware of any potential adverse events associated with the product.

Only 3 of these women were receiving hormone replacement therapy. Younger men and women deposited similar amounts of collagen. Therefore, older men made less collagen after surgery than older women, perhaps explaining the consistent observation that wound dehiscence is twice as common in men than in women.

 - Он прикинул в уме, сколько в этой пачке в пересчете на доллары.  - Да тут несколько тысяч долларов. - Я действую по инструкции, сэр.  - Пилот повернулся и скрылся в кабине. Дверца за ним захлопнулась.

 Джабба, мне не до шуток. - Ну хорошо, - сказал он, приподнимаясь на локтях.  - Может быть, у них закоротило генератор. Как только освобожусь, загляну в шифровалку и… - А что с аварийным питанием. Если закоротило генератор, почему оно не включилось. - Не знаю.
