Polyacrylamide-Sodium Alginate Hydrogel Releasing Oxygen and Vitamin C Promotes Bone Regeneration in Rat Skull Defects

open access: yesFrontiers in Materials, 2021
Oxygen is essential for cell survival and tissue regeneration. Scaffolds releasing oxygen have been hypothesized as an ideal strategy for bone repair. However, excessive oxygen supply will disturb the redox balance, lead to oxidative stress, and affect ...

General analysis of mathematical models for bone remodeling

open access: yes, 2010
Bone remodeling is regulated by pathways controlling the interplay of osteoblasts and osteoclasts. In this work, we apply the method of generalized modelling to systematically analyse a large class of models of bone remodeling.

Skeletal Microdamage: Less About Biomechanics and More About Remodeling [PDF]

open access: yes, 2008
The mechanical consequences of skeletal microdamage have been clearly documented using various experimental methods, yet recent experiments suggest that physiological levels of microdamage accumulation are not sufficient to compromise the bones ...

Research progress on the role and mechanism of miR-671 in bone metabolism and bone-related diseases

open access: yesFrontiers in Oncology, 2023
Bone metabolism consists of bone formation and resorption and maintains a dynamic balance in vivo. When bone homeostasis is broken, it can manifest as osteoarthritis (OA), rheumatoid arthritis (RA), osteosarcoma (OS), etc.

Mineral maturity and crystallinity index are distinct characteristics of bone mineral [PDF]

open access: yes, 2010
The purpose of this study was to test the hypothesis that mineral maturity and crystallinity index are two different characteristics of bone mineral. To this end, Fourier transform infrared microspectroscopy (FTIRM) was used.

Hematopoietic (stem) cells—The elixir of life?

open access: yesFEBS Letters, EarlyView.
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.
