ASSESSMENT OF PERI-IMPLANT BONE MICROARCHITECTURE IN D4 BONE: AN EX VIVO MICROCT ANALYSIS
… stability quotient (ISQ), and peri-implant bone microarchitecture in low-density bone (D4). The investigation focused on three Straumann implant systems: Bone Level Tapered (BLT), Bone Level X (BLX), and Tissue Level (TL). Materials and Methods: An ex vivo model utilizing porcine tibia bone …

The effect of continuous infusion of human parathyroid hormone on bone architecture in female mice
… for either 2 week or 4 week duration. Total body bone mineral density (BMD) and bone mineral content (BMC), trabecular and cortical bone microarchitecture, and serum calcium levels were measured. There were no significant differences in BMD or BMC in either study in mice infused with either …

Using finite element models under multiple loading conditions to improve the association between radius and tibia microarchitecture and prevalent osteoporotic vertebral fracture
Bone microarchitecture differences at the tibia and radius, measurable by high-resolution peripheral quantitative computed tomography (HR-pQCT) exist between individuals with a prevalent vertebral fracture and healthy controls. As fracture is a result of mechanical failure, FE models of these sites …

Interactions Between Aging and Chronic Kidney Disease on the Skeleton
… treatment was associated with higher trabecular bone volume, lower cortical porosity, and higher mechanical properties compared to control animals. Combination treatment also resulted in benefits to trabecular bone volume and mechanical properties. These results demonstrate that both romosozumab …

Bone Mineral Density In Hiv: A Comparison Of Hiv Positive Versus Negative Patient With Lower Limb Long Bone Fractures
… a global health issue causing a deterioration in bone microarchitecture, compromising bone strength. In South Africa (SA), the prevalence of osteoporosis is a growing concern for both HIV-positive and HIVnegative individuals. The aim of this study was to assess the impact of HIV infection on bone …

Bone Properties of Recombinant Inbred Line - BXD Mouse
<p>Osteoporosis is identified by reduced bone mass, decreased bone quality and altered bone micro-architecture. These traits are quantitative and also highly regulated by genetic and environmental factors. As a powerful tool for collaborative analysis of quantitative traits and gene function, BXD …

In vivo imaging of cortical porosity by synchrotron phase contrast micro computed tomography
Cortical bone is a dynamic tissue which undergoes adaptive and pathological changes throughout life. An improved understanding of the spatio-temporal process of remodeling holds great promise for improving our understanding of bone development, maintenance and senescence. The use of micro-computed …

Osteocyte Activity and Skeletal Muscle Relative Gene Expression Profiling After Short-term Muscle Paralysis
… loading is essential for maintaining bone tissue. Reduced mechanical loading has been shown to have a negative effect on bone, and can result in the development of disuse osteoporosis. Disuse models of muscle inactivity and immobilization, like the Botox model used in this study, …

The Ability of Bone Mineral Density and Microstructural Indices to Reflect Mechanical Properties of Trabecular Bone
… and biomechanical properties of trabecular bone in the intertrochanteric region (2) investigate contribution of bone mineral density (BMD) and microstructure of trabecular bone to predicting its mechanical property, i.e., elastic modulus, and (3) determine if the prediction of bone elastic …

Role of the RUNX2 rs59983488 variant in bone mass determination and fracture risk in Malta
… disease which is characterised by a reduced bone density (BMD) and compromised bone microarchitecture, leading to an increased fragility fracture risk. The Runt-related Transcription Factor 2 (RUNX2) protein encoded by the RUNX2 gene is involved in the maturation and differentiation of …

The Fruit of Poncirius Trifoliata Promotes Mesenchymal Stem Cell Differentiation into Osteoblasts in Glucocorticoid-induced Osteoporosis Model
… (DEX)-treated MC3T3-E1 cells and primary bone marrow mesenchymal stem cells (BMSCs). Five fractions of ethyl acetate extract of poncirus trifoliata through column chromatography over a silica gel eluting in gradient system and combined based on their thin layer chromatography (TLC) …

Investigating Feeding Omega-3 Polyunsaturated Fatty Acids and/or Soy Protein Isolate to Female pck Rats on Polycystic Kidney Disease and Related Complications
… are at risk of complications that include bone loss and polycystic liver disease (PLD). Currently, no genetic therapy or effective pharmacological treatments exist. Therefore, dietary intervention offers a potentially efficacious, cost-effective, and safe therapeutic option for PKD and …

Diet and lifestyle interventions to improve co-morbid conditions of chronic kidney disease
… and quality of life, including muscle wasting, bone disorders, and cardiovascular disease. Protein-energy malnutrition is especially common for reasons including poor nutrient intake, amino acid losses during dialysis, and elevated intradialytic catabolism; these factors promote loss of lean …
