Proper mechanical stress promotes femoral head recovery from steroid-induced osteonecrosis in rats through the OPG/RANK/RANKL system

open access: yesBMC Musculoskeletal Disorders, 2020
Background Long-term use of steroid may lead to osteonecrosis of the femoral head (ONFH). Mechanical stress may help bone formation and remodeling. This study aimed to probe the role of mechanical stress in the femoral head recovery in rats.

Bioenergetic Materials for Tissue Regeneration: Modulating Metabolism to Promote Cellular Anabolism

open access: yesAdvanced Science, EarlyView.
Bioenergetic materials (BEMs) modulate cellular metabolism to promote tissue regeneration. Their principal mechanisms of action include metabolic substrate supplementation, metabolic enzyme modulation, organelle transfer, electrical current regulation, redox homeostasis modulation, and oxygen tension modulation.

A Novel Reactive Oxygen Species‐Responsive Bone‐Targeted Nanoplatform Based on Cloperastine Attenuates Ovariectomy‐Induced Bone Loss by Inhibiting Osteoclast Oxidative Phosphorylation

open access: yesAdvanced Science, EarlyView.
Cloperastine suppresses osteoclastogenesis by inhibiting PGC1β‐mediated oxidative phosphorylation. Its incorporation into a ROS‐responsive, Asp8‐modified nanoplatform enhances skeletal accumulation. The resulting Clo/Asp8‐PMK‐MCs combine cloperastine‐mediated antiresorptive activity with carrier‐mediated osteogenic activity to attenuate OVX‐induced ...

Chinese Expert Consensus on the Clinical Application of Finerenone in Geriatric Comorbidities

open access: yesAGING MEDICINE, EarlyView.
Mineralocorticoid receptor (MR) overactivation drives inflammation, oxidative stress, and fibrosis in the heart, kidneys, and vasculature, leading to cardiorenal dysfunction. MR signaling promotes hypertrophy, remodeling, and injury through pathways like oxidative stress and inflammation, resulting in vascular stiffness and progressive organ damage ...

Hip Arthroscopy in Adults Aged 40 or Older Produces Clinically Meaningful Symptom Improvement but Carries a Substantial Risk of Conversion to Total Hip Arthroplasty: A Systematic Review

open access: yesArthroscopy, EarlyView.
Purpose To report conversion rates to total hip arthroplasty (THA), patient‐reported outcome measures, and complication rates in adults aged ≥ 40 years undergoing hip arthroscopy since 2016. Methods MEDLINE, EMBASE, and PubMed were searched from January 2016 to March 2025, and pertinent data were abstracted from eligible studies according to the ...

Atraumatic osteonecrosis of the humeral head: pathophysiology and current concepts of evaluation and treatment

open access: yesJSES Reviews, Reports, and Techniques, 2022
The humeral head is considered the second most common site for osteonecrosis to occur after the femoral head. As seen in the femoral head, the circulatory implications characteristic of this condition are attributable to the interaction between a genetic

Low expression of vascular endothelial growth factor and high serum level of cyclic guanine monophosphate as the risk factors of femoral head osteonecrosis in alcohol-exposed Wistar rat

open access: yesChinese Journal of Traumatology, 2020
Purpose: Severe damage to the femoral head in patients with osteonecrosis has a high impact on morbidity. Despite early diagnosis, the treatment outcome is still unsatisfactory.
