introduction: low level laser therapy (lllt) also known as photobiomodulation, is a treatment that uses low-level lasers or light-emitting diodes (leds) to change cellular function and is a clinically well accepted tool in regenerative medicine and dentistry. considering the variety of laser, exposure, cells and study types, the exact effects of low level laser therapy seems to be unclear. the ...

Purpose. Guided tissue reconstruction can be performed to restore the supporting structure of a previously lost tooth, which, in addition maintaining beauty, preserves function tooth patient. Materials and Methods. In this review, Scopus, PubMed, MEDLINE databases were searched using keywords “biocompatible materials,” “membrane,” “bone regeneration,” “tissue reconstruction,” “dental biomateria...

Recently a novel crosslinkable and biodegradable copolymer poly(propylene fumarateco-caprolactone) (PPF-co-PCL) has been synthesized in our lab (Figure 1). By varying copolymer composition, controllable physical properties can be achieved to satisfy various needs in tissue engineering, particularly, bone and nerve regenerations. The physical properties of the copolymers have been extensively in...

OBJECTIVES In this study, Adipose stem cells (ADSC) and bone marrow stem cells (BMSC), multipotent adult cells with the potentials for cartilage regenerations were induced to chondrogenic lineage and used for cartilage regenerations in surgically induced osteoarthritis in sheep model. METHODS Osteoarthritis was induced at the right knee of sheep by complete resection of the anterior cruciate ...

Norit Carbon has developed a chemically regenerable activated carbon (SPARAC) that is suitable for sugar decolourisation. Previous evaluation of this activated carbon showed promising results, and Norit developed another grade of SPARAC that had faster adsorption kinetics. This carbon has been evaluated in terms of its colour removal performance after successive regenerations. Decolourisation t...

Small bleaches were used to study the rhodopsin regeneration process. At bleaches from 5.2% to 24.7%, the rhodopsin regenerations were consistent with a one-for-one recovery of bleached molecules. At response saturation rod photoreceptors exhibit a bleach level of only 5%. Major increases in rhodopsin regeneration were observed at bleach levels between 1.3% and 5.2%. The rhodopsin regenerations...

Transient analysis of Markov Regenerative Processes (MRPs) can be performed through the solution of Markov renewal equations defined by global and local kernels, which respectively characterize the occurrence of regenerations and transient probabilities between them. To derive kernels from stochastic models (e.g., stochastic Petri nets), existing methods exclusively address the case where at mo...

AIM This research was conducted to clarify the capability of human umbilical mesenchymal stem cells conditioned medium (HU-MSCM) to promote regenerations of primary wound healing on the incision skin injury. MATERIALS AND METHODS In this study, two approaches in vitro and in vivo already done. On in vitro analysis, tube formation was performed using HU vein endothelial cells in the presence o...
