Longer Acting Injectable: Continuous, Linear Release of a Progestin Contraceptive From an Oxidized Porous Silicon Host

open access: yesAdvanced Healthcare Materials, EarlyView.
Progestin drugs are loaded into a mesoporous silicon dioxide host by melt‐infiltration. Drugs that decompose at or close to their melting point can be loaded by the addition of cholesterol, which acts as a melting point suppressor. High mass loading of the drug is achieved, and dissolution of the composite is controlled by the nanoscale properties of ...

TPMS‐Gyroid Scaffold‐Mediated Up‐Regulation of ITGB1 for Enhanced Cell Adhesion and Immune‐Modulatory Osteogenesis

open access: yesAdvanced Healthcare Materials, EarlyView.
A) SLM generates biomimetic bone scaffolds with consistent porosity but varying TPMS‐Gyroid unit cell designs (TG15, TG20, TG25, TG30). B) By enhancing the expression of ITGB1, TPMS‐Gyroid scaffolds can facilitate osteogenic differentiation in BMSCs and promote M2 polarization in macrophages.

Tensile material properties of human rib cortical bone under quasi-static and dynamic failure loading and influence of the bone microstucture on failure characteristics [PDF]

open access: yesarXiv, 2011
Finite element models of the thorax are under development to assist vehicle safety researchers with the design of countermeasures such as advanced restrain systems. Computational models have become more refined with increasing geometrical complexity as element size decreases.

RANK/RANKL/OPG pathway: genetic associations with stress fracture period prevalence in elite athletes [PDF]

open access: yes, 2014
Context: The RANK/RANKL/OPG signalling pathway is important in the regulation of bone turnover, with single nucleotide polymorphisms (SNPs) in genes within this pathway associated with bone phenotypic adaptations.

Enhancing Form Stability: Shrink‐Resistant Hydrogels Made of Interpenetrating Networks of Recombinant Spider Silk and Collagen‐I

open access: yesAdvanced Healthcare Materials, EarlyView.
A shrinkage‐resistant hydrogel is developed to confer post‐fabrication shape fidelity. The hydrogel, based on recombinant spider silk protein eADF4(C16)‐RGD and collagen‐I, exhibits tunable mechanical properties and shrink‐resistance in the presence of fibroblasts as well as muscle cells.

Introducing Anisotropic Minkowski Functionals for Local Structure Analysis and Prediction of Biomechanical Strength of Proximal Femur Specimens [PDF]

open access: yesMaster's Thesis - 2013, 2020
Bone fragility and fracture caused by osteoporosis or injury are prevalent in adults over the age of 50 and can reduce their quality of life. Hence, predicting the biomechanical bone strength, specifically of the proximal femur, through non-invasive imaging-based methods is an important goal for the diagnosis of Osteoporosis as well as estimating ...

Prone position in balloon kyphoplasty leads to no secondary vertebral compression fractures in osteoporotic spine – a MRI study

open access: yesGMS Interdisciplinary Plastic and Reconstructive Surgery DGPW, 2014
Purpose: Vertebral compression fractures are the most common fractures in the elderly. Long lasting pain and deformity is responsible for consecutive impairment with markedly reduced life quality, increased morbidity and mortality. The beneficial effects
