Effect of sonic hedgehog/β-TCP composites on bone healing within the critical-sized rat femoral defect

open access: yes, 2013
The creation of entirely synthetically derived bone substitute materials which are as effective as autologous bone grafts is desirable. Osteogenesis involves the concerted action of several proteins within a signaling cascade.

Topology‐Enriched Toughness Enhancement in Quasi‐Periodic Metastructures Featuring Tailorable Strong‐Weak Network

open access: yesAdvanced Science, EarlyView.
A quasi‐periodic Dart‐Kite (QDK) metastructure with a golden‐ratio‐constrained strong–weak bond network simultaneously enhances strength, toughness, and damage tolerance. Its distributed topology enables predictable, tailorable crack paths for precise fracture control and stable mechanics, demonstrating a high‐performance, controllable architecture ...

Unraveling the Power of Disorder: A Bioinspired Cuttlebone Structure With Superior Strength, Energy Absorption and Isotropy

open access: yesAdvanced Science, EarlyView.
Cuttlebone‐inspired architected metamaterials introduce controlled structural disorder to simultaneously enhance strength, energy absorption, and compressive stability. Tunable disorder suppresses shear anisotropy, outperforms periodic lattices, and establishes discrete randomness as a robust route to high‐performance lightweight mechanical ...

BONE STRENGTH OF DIFFERENT PIGS GENETIC TYPES [PDF]

open access: yes, 2010
The aim of this study was to evaluate the bone strength in different genetic types of pigs. Nowadays, in swine production it is rather common to obtain pigs with weak bones, especially on the hind legs.

A Piezo‐Mimetic Ionic Hydrogel Harnessing Joint Motion for Cartilage Repair

open access: yesAdvanced Science, EarlyView.
A piezo‐mimetic ionic hydrogel converts mechanical deformation into bioactive ionic currents via stress‐induced asymmetric ion migration. Coupled with sustained Mg2+ release, this mechano‐electrochemical platform bridges mechanical loading and cellular signaling, enabling load‐adaptive stimulation and enhanced cartilage regeneration. ABSTRACT Articular

Orchestrated Engineered Polyphenol‐Peptide Condensates Coupled With β‐GP Reverses Diabetic Osteoporosis by Remodeling Mitophagy

open access: yesAdvanced Science, EarlyView.
A multifunctional β‐GP@EGCG‐E7 nanoplatform is engineered by polyphenol–peptide condensation and phosphate loading. Bone‐targeted delivery, antioxidant and anti‐inflammatory activity, and mitophagy restoration are integrated in one system, enabling protection of osteoblasts and endothelial cells and promoting bone regeneration under diabetic ...

Effect of anastrozole on bone mineral density and lipid profiles when used to prevent breast cancer in high risk postmenopausal women

open access: yes, 2012
PhDThe role of aromatase inhibitors (AIs) in breast cancer has expanded since their introduction in the mid-1990s. They are superior to tamoxifen in the treatment of postmenopausal women with oestrogen dependant tumours in the metastatic, neoadjuvant ...
