RISEffect of amount of tetra ethyl orthosilicate and thermal treatment temperatureon mechanical and biological properties of gelatin calcium phosphate scaffolds
) composite scaffold in bone tissue engineering (BTE) which can
regenerate bone damages successfully. Variety of materials have been
utilized to create novel alternatives instead of conventional ones which
had some disadvantages...
The effects of decellularization methods on biological properties of human dermal matrix scaffolds
Regenerative medicine and tissue engineering focus on replacing and restoring damaged cells, tissues,
and organs as a new discipline in biomedical research, and for this purpose, three-dimensional (3D)
scaffolds are used combination...
Three-Dimensional Scaffold from Decellularized Human Gingiva for Cell Cultures: Glycoconjugates and Cell Behavior
to prepare 3D scaffolds, human palatal gingival biopsies were harvested and physically decellularized by freezethawing and sodium dodecyl sulfate (SDS). The scaffolds were placed within the rings of blastema tissues obtained from a pinna rabbit, in vitro. We...
Symmetrical or Asymmetrical Scaffolding: Piagetian vs. Vygotskyan Views to Reading Comprehension
This study seeks to investigate the impact of symmetrical (S) and Asymmetrical (AS) scaffolding, which are two types of scaffolding, on students' reading comprehension achievement of English as a Foreign Language (EFL). The study was done in two...
Peer scaffolding behaviors emerging in revising a written task: A microgenetic analysis
Vygotsky's writings on Sociocultural Theory (SCT) of mind, his concept of Zone of Proximal Development (ZPD) and its related metaphor, scaffolding, serve as the theoretical basis for the study of peer collaboration. This paper aimed at examining...
Treatment of Critical-Sized Calvarial Non-Union Defect Via Collagen-Polyglycolic Acid Scaffold Loading With Simvastatin in Rabbits
The objective of the present study is to enquire into the effects of a sustained-release simvastatin in collagen-polyglycolic acid scaffold on bone formation in the rabbit calvarial critical size defect. A study was carried out to examine if maximum...
The preparation of kidney natural scaffolds containing glycoproteins for preliminary tissue engineering applications
Background: The extracellular matrix (ECM) is a complex mixture of both structural and functional molecules arranged in a tissue specific three-dimensional architecture. Basement membrane ECM and non basement membrane ECM have been used as scaffolds...
Preparation and application of natural scaffolds in tissue engineering
In the past two decades, tissue engineering has
shown a great potential in regeneration of various
tissues and organs. Three important components in this technology include scaffolds, cells...
Application of the bacterial cellulose as a bioscaffold
. Because of its unique properties, it can be used as scaffold for vascular, bone, cartilage, heart valve, tendon, smooth muscle cells and other tissues both in vito and in vivo.
Methods
Bacterial cellulose membranes were produced from...
