OBJECTIVE
Oversuppression of bone turnover can be a critical factor in the pathogenesis of osteonecrosis of the jaw (ONJ). We investigated N-telopeptide of type I collagen (NTX) and bone-specific alkaline phosphatase (BAP) as potential predictors of ONJ onset.
METHODS
Patients with ONJ and available
OBJECTIVE
We aimed to investigate whether miR-181d may be involved in steroid-induced osteonecrosis of the femoral head (ONFH) and its underlying mechanism.
METHODS
Quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR) was used to detect the expression of miR-181d in bone marrow of
Synovitis of the affected joint is a common in avascular osteonecrosis (AVN). Increased levels of pro-inflammatory cytokine interleukin-6 (IL-6) have been reported in AVN, but the mechanism of this increase remains unclear. Silent information regulator transcript-1 (SIRT1), an NAD-dependent
P-glycoprotein (P-gp) plays a role in steroid-induced osteonecrosis of the femoral head (ONFH), but the underlying mechanism remains unknown. We hypothesized that P-gp overexpression can prevent ONFH by regulating bone marrow-derived multipotent stromal cell (BMSC) adipogenesis and osteogenesis.
Idiopathic osteonecrosis of the femoral head (ION) is a painful disease of the hip, the pathogenic mechanism of which is still unclear. The most common extraneous factor is steroid treatment. Steroids have inhibiting effects on bone formation and resorption. When bone regenerative treatments are
In this study, we aimed to identify a candidate drug that can activate endogenous Angiopoietin 1 (Ang1) expression via drug repositioning as a pharmacological treatment for avascular osteonecrosis. After incubation with 821 drugs from the Food and Drug Administration (FDA)-approved drug library,
Bone biomarkers have been suggested for the risk assessment for osteonecrosis of the jaw, a serious complication associated with bisphosphonate (BP) use; however, no consensus has been reached. This study investigated the possible associations between bone biomarkers and the development of
BACKGROUND
Femoral head osteonecrosis is frequently observed in patients treated with excessive corticosteroids. The objective of the current study was to establish a rat model to investigate the disruption of immune response in steroid-induced femoral head osteonecrosis via Toll-like receptor 4
Osteonecrosis of the femoral head is frequently observed in patients treated with excessive corticosteroids. However, the pathogenesis of corticosteroid-induced osteonecrosis remains unclear. The purpose of this study was to investigate the role of Toll-like receptor 4 (TLR4) signaling pathway in
Prostaglandin E2 (PGE2)-like activity was measured in osteonecrotic femoral heads caused by high doses of methyl prednisolone acetate in rabbits. Serum levels of cholesterol, total lipids, free fatty acids, alkaline phosphatase, SGOT and lipase were also determined. There were increases in local
There are a lot study confirmed the relationship of bone serum markers changes and skeletal irregularities. But there is no sufficient case control studies about the role of these markers on bisphosphonate induced osteonecrosis of jaws (BRONJ).The aim of OBJECTIVE
The aim of this study was to evaluate bone metabolism in patients with spontaneous osteonecrosis (ON) of the medial femoral condyle.
METHODS
In 22 consecutive patients, undergoing total knee arthroplasty, biochemical markers of bone metabolism were measured in aspirates from cancellous
Purpose: In this study, we aimed to investigate the effect of glucose metabolism on bone healing after tooth extraction in an osteoporosis rat model administered zoledronic acid (ZA) and dexamethasone (DX).
Bisphosphonate (BP) related osteonecrosis of the jaw (BRONJ) and dental implant failure are two negative side effects of chronic aminoBP treatment.METHODS
Eleven ovariectomized (OVX) ewes and 4 ewes subjected to sham surgery (SHAM) were treated as
