In bone tissue engineering, the organo-ceramic composite, electrospun polycaprolactone/hydroxyapatite (PCL/HA) scaffold has the potential to support cell proliferation, migration, differentiation, and homeostasis. Here, we report the effect of PCL/HA scaffold in tissue regeneration using human mesenchymal stem cells (hMSCs). We characterized the scaffold by fourier transform infrared spectrosco...

The synthesis of a new triazacyclophane scaffold (TACO scaffold) containing three selectively deprotectable amines is described. The TACO scaffold is conformationally more constrained than our frequently used TAC scaffold, due to introduction of a substituent on the para position of the benzoic acid hinge, which prevents ring flipping and makes it more attractive than the TAC scaffold for prepa...

introduction perforation of maxillary sinus mucous membrane is of the most prevalent complication during open sinus lift surgery. moreover, such complication can usually be managed by an absorbable membrane. as far as absorbable membranes are concerned, decellularized maxillary sinus mucous membranes, which is an extracellular matrix, can be used as a biologic scaffold and insulating membrane i...

traumatic brain injury (tbi) is described by a disruption in the normal function of the brain due to an injury following a trauma, which can potentially cause severe physical, cognitive, and emotional impairment. the use of human stem cells and self-assembling peptide scaffolds suggest huge potential for application in the treatment of tbi. in the present study, we surveyed the beneficial effec...

Biodegradable scaffolds play a critical role in therapeutic tissue engineering, in which the matrix degradation and tissue ingrowth are of particular importance for determining the ongoing performance of tissue-scaffold system during regenerative process. This paper aims to explore the mechanobiological process within biodegradable scaffolds, where the representative volume element (RVE) is ext...

We present here-designed, manufactured, and tested by our research team-the Ti-alloy prototype of the multispiked connecting scaffold (MSC-Scaffold) interfacing the components of resurfacing arthroplasty (RA) endoprostheses with bone. The spikes of the MSC-Scaffold prototype mimic the interdigitations of the articular subchondral bone, which is the natural biostructure interfacing the articular...

This paper introduces a digital safety monitoring device for attached lifting scaffold, including scaffold and control device. The includes point, intermediate station, center, communication converter, display mobile terminal. point is set on the wirelessly connected with station. station transmits data to center through network mapping. respectively converter utility model has simple structure...

Suitable alternatives are made for damaged or diseased organs and tissues in tissue engineering by combining cellular and molecular biology with materials and mechanical engineering. Fibrin is a critical blood component responsible for homeostasis, used extensively as a biopolymer scaffold in tissue engineering. This study summarizes the latest developments in organ and tissue regeneration usin...

Bone tissue engineering implants with sustained local drug delivery provide an opportunity for better postoperative care for bone tumor patients because these implants offer sustained drug release at the tumor site and reduce systemic side effects. A rapid prototyped macroporous polycaprolactone scaffold was embedded with a porous matrix composed of chitosan, nanoclay, and β-tricalcium phosphat...

Combining a nanocomposite technique and the electrospinning process, a robust dual-porosity scaffold structure was developed for a facile transport of metabolic nutrients and wastes through the nano-sized pores and for the cell implantation and blood vessel invasion through the micro-sized pores. The montmorillonite (MMT) nano-sized platelets were incorporated into poly(L-lactic acid) (PLLA) so...
