Journal of Bone and Mineral Research, 2020 Osteoarthritis (OA) and osteoporosis (OP) are two skeletal disorders associated with joint structures. Occasionally, OA and OP occur in the same patient. However, the effect of OP changes on OA progression in patients with osteoporotic OA (OP‐OA) has not

The influence of bone surface availability in bone remodelling - A mathematical model including coupled geometrical and biomechanical regulations of bone cells [PDF]
Eng Struct (2013) 47:134-147, 2012 Bone is a biomaterial undergoing continuous renewal. The renewal process is known as bone remodelling and is operated by bone-resorbing cells (osteoclasts) and bone-forming cells (osteoblasts). Both biochemical and biomechanical regulatory mechanisms have been identified in the interaction between osteoclasts and osteoblasts.

D-methionine eradicates Porphyromonas gingivalis biofilms by suppressing the cyclic di-GMP level
口腔疾病防治, 2022 Objective To investigate the mechanisms by which D-methionine (D-Met) eradicates Porphyromonas gingivalis biofilms by suppressing cyclic dimeric GMP (c-di-GMP) levels.

Concurrent consideration of cortical and cancellous bone within continuum bone remodelling [PDF]
, 2020 Continuum bone remodelling is an important tool for predicting the effects of mechanical stimuli on bone density evolution. While the modelling of only cancellous bone is considered in many studies based on continuum bone remodelling, this work presents an approach of modelling also cortical bone and the interaction of both bone types.

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

Bone remodelling at a glance [PDF]
Journal of Cell Science, 2011 The bone remodelling cycle (see Poster panel “The bone remodelling cycle”) maintains the integrity of the skeleton through the balanced activities of its constituent cell types. These are the bone-forming osteoblast, a cell that produces the organic bone matrix and aids its mineralisation ([

Investigation of the cellular response to bone fractures: evidence for flexoelectricity [PDF]
Scientific Reports volume 10, Article number: 254 (2020), 2020 The recent discovery of bone flexoelectricity (electrical polarization induced by strain gradient) suggests that flexoelectricity could have physiological effects in bones, and specifically near bone fractures, where flexoelectricity is theoretically highest. Here, we report a cytological study of the interaction between crack stress and bone cells. We

Endocortical bone loss in osteoporosis: The role of bone surface availability [PDF]
Int J Numer Meth Biomed Engng (2013) 29:1307-1322, 2012 Age-related bone loss and postmenopausal osteoporosis are disorders of bone remodelling, in which less bone is reformed than resorbed. Yet, this dysregulation of bone remodelling does not occur equally in all bone regions. Loss of bone is more pronounced near and at the endocortex, leading to cortical wall thinning and medullary cavity expansion, a ...

Regulation of epigenetic modifications in the head and neck tumour microenvironment
Frontiers in Immunology, 2022 Head and neck tumours are common malignancies that are associated with high mortality. The low rate of early diagnosis and the high rates of local recurrence and distant metastasis are the main reasons for treatment failure.

Oxidative stress in bone remodeling: role of antioxidants.
CLINICAL CASES IN MINERAL AND BONE METABOLISM, 2017 ROS are highly reactive molecules which consist of a number of diverse chemical species, including radical and non-radical oxygen species. Oxidative stress occurs as a result of an overproduction of ROS not balanced by an adequate level of antioxidants ...
