the matrix functions appear in several applications in engineering and sciences. the computation of these functions almost involved complicated theory. thus, improving the concept theoretically seems unavoidable to obtain some new relations and algorithms for evaluating these functions. the aim of this paper is proposing some new reciprocal for the function of block anti diagonal matrices. more...

In recent years the science of tissue engineering has emerged as a powerful tool for the development of a novel set of tissue replacement parts and technologies. Recent advances in the fields of biomaterials, stem cell technologies, growth factor field and biomimetics have created a unique set of opportunities for investigators to fabricate lab-grown tissues from combination of extracellular ma...

A provisional matrix consisting of fibrin and fibronectin (FN) is deposited at sites of tissue damage and repair. This matrix serves as a scaffold for fibroblast migration into the wound where these cells deposit new matrix to replace lost or damaged tissue and eventually contract the matrix to bring the margins of the wound together. Tenascin-C is expressed transiently during wound repair in t...

The role of heart disease in increasing worldwide death and the limited availability of organs for transplantation have encouraged multiple strategies to fabricate functional and implantable constructs. One of these strategies is to develop a biologically similar heart tissue scaffold, in which two types of fiber and hydrogel are commonly used. Toward this goal, taking advantage of both hydroge...

naturally the brain is ineffective in regenerating functional tissue after disease or injury, so to overcome these defects innovative curative strategies such as stem cell transplantation and tissue engineering have to be considered. researchers investigate the use of strategies to attain better functional repair results. one of the important challenges of effective transplantation is the deliv...

extracelllar matrix (ecm) materials from mammalian tissues have been broadly used for tissue engineering for animal models. while decellularization of tissues such as bladder, heart valve, knee meniscus and tendon has been performed, there are a few reports for articular cartilage. in this study we aimed to develop a technique to decellularize bovine articular cartilage as a biological construc...
