Sarcomas arising from the chest wall account for less than 20% of all soft tissue sarcomas, and at this site, primitive tumors are the most frequent to occur. Leiomyosarcoma is a malignant smooth muscle tumor and the best outcomes are achieved with wide surgical excision. Although advancements have been made in treatment protocols, leiomyosarcoma remains one of the more difficult soft tissue sa...

Skin of 14-day icjic and + / + embryos was separated into dermal and epidermal layers using trypsin, and recombined in the combinations + /+ epidermis with + /+ dermis, +/ + epidermis with icfic dermis, icjic epidermis with + /+ dermis, and icjic epidermis with ic/ic dermis. The recombined tissues were implanted in adult histocompatible testes and allowed to grow for 2 weeks. The type of hair t...

BACKGROUND Over recent decades, scientists and surgeons have collaborated to develop various bioengineered and synthetic products as an alternative to skin grafts. Despite the numerous articles and reviews written about dermal skin substitutes, there is no general consensus. METHODS This article reviews dermal skin scaffolds used in clinical applications and experimental settings. For scaffol...

A number of implantable biomaterials derived from animal tissues are now used in modern surgery. Xe-Derma is a dry, sterile, acellular porcine dermis. It has a remarkable healing effect on burns and other wounds. Our hypothesis was that the natural biological structure of Xe-Derma plays an important role in keratinocyte proliferation and formation of epidermal architecture in vitro as well as i...

The oxidative potential (OP) of particulate matter (PM) has recently been considered as a viable health-based metric PM exposure. Several acellular assays have developed to assess OP, but...

background: this study aimed to assess dermis fat graft (dfg) as a choice to correct the tissue deficit in the free border of the upper lip in cleft lip repair surgery. materials and methods: thirty?five individuals who referred to alzahra hospital at 2013–2014,with lip deformity following the primary repair surgery of cleft lip underwent surgery by dfg technique. outcomes were assessed 4 month...

The dermis of sea cucumbers is a catch connective tissue or mutable collagenous tissue that shows large changes in stiffness. Extensive studies on the dermis revealed that it can adopt three different states having different mechanical properties that can be reversibly converted. These are the stiff, standard and soft states. The standard state is readily produced when a dermal piece is immerse...

The dermis in the holothurian body wall is a typical catch connective tissue or mutable collagenous tissue that shows rapid changes in stiffness. Some chemical factors that change the stiffness of the tissue were found in previous studies, but the molecular mechanisms of the changes are not yet fully understood. Detection of factors that change the stiffness by working directly on the extracell...

Introduction Acellular corneal matrix, with its fine biocompatibility and strength for suturing, are being developed to replace part or full thickness of diseased corneas[1]. The bioactivity of acellular corneal matrix can be modified to the purpose of permitting host tissue regeneration. AECs innoculation may produce a mimetic model of corneal epithelium, which could promote outgrowth of cells...
