Summary: This study demonstrates a clear mechano-responsiveness in bursa-derived cells with activation of mechano-transduction pathways, suggesting a physiological function of mechanical loading in these cells. The findings provide a basis for further research that may lead to improved treatment options for subacromial bursa-related pathologies in the future.

Summary: This paper investigates the relationship between aging and mechano-transduction in red blood cells and discovers that mechanical stimulation can accelerate the aging process. The behavior of cellular effectors and resources is evaluated in the presence of drugs and specific inhibitors. The findings provide a comprehensive perspective on cell-environment interactions and demonstrate the direct correlation between aging and mechano-transduction.

Summary: Incorporating mechanical cues into cellular responses allows cells to perceive and respond to physical properties such as vibration and pressure. Mechanical forces shape cellular responses and tissue development. GPCRs, including angiotensin II type 1 receptor and adrenergic, apelin, histamine, parathyroid hormone 1, and orphan receptors, play a crucial role in mechanosensation. Different types of mechanical activation, such as shear stress and cell swelling/stretch, affect these receptors. The contribution of force-from-lipid and force-from-tether models in ion channels is also discussed.

Summary: The study aimed to quantify the local effect of mechanical loading on cortical bone formation at the periosteal surface using mouse tibia mu CT data. A novel image analysis algorithm was developed to analyze cortical thickness changes due to different peak loads. Results showed a strong association between Delta Ct.Th and peak loads in certain periosteal positions, particularly those experiencing high compressive or tensile strains. However, no significant association was found in regions around the neutral axis. The bone formation responses were dependent on load magnitude and periosteal position, with bone resorption occurring in regions throughout the cross-sectional area of the loaded tibia.

Summary: This review article discusses nanoarchitectonics approaches for mechanically responding materials, focusing on the importance of mechanical control of supramolecular assemblies and materials, as well as the control and evaluation of atom/molecular level structures. The special attention given to interfacial environments for mechano-nanoarchitectonics is emphasized. The coupling of macroscopic mechanical forces and molecular-level phenomena and the control of living cells at liquid-liquid interfaces are also discussed.

Summary: This study aimed to evaluate the influence of estrogen deficiency and mechanical loading on bone around osseointegrated dental implants in a rat jaw model. The results showed that estrogen deficiency could affect the long-term stability of implants, while mechanical loading could attenuate the negative effects of estrogen deficiency on bone formation and osseointegration.

Summary: Cells respond to both biochemical and biomechanical changes in their microenvironment, and this study reveals an integrin-GSK3 beta-FTO-mTOR axis that can sense substrate stiffness and promote cell growth on rigid substrates while also providing resistance to cell death upon matrix detachment. The study demonstrates that substrate stiffening activates mTORC1 and increases mTOR levels through integrins and GSK3 beta-FTO mediated mRNA m6A modification, promoting anabolic metabolism. Inhibition of this axis enhances autophagy upon ECM detachment, providing tumor cells resilience against anoikis. These findings highlight the importance of mechanical force in cellular metabolism and its role in tumor growth and metastasis.

Summary: The in vivo mouse tibial loading model was used to evaluate mechanical loading treatment for skeletal diseases, focusing on the effect of passive mechanical loading on strain distribution in the mouse tibia and predictions of bone adaptation. The study found similar accuracy in the model and spatial match for various loading conditions, with combined loading showing the most similar predictions to experimental data.

Summary: The cellular microenvironment is heterogeneous and dynamic. Mechanical force is an important input that activates signaling and regulates cell behavior through mechanotransduction. However, the reversibility of mechanical signaling is not well understood.

Summary: Cell behaviors depend on the elastic properties of the microenvironments, which differ from polymer-based substrates. Metamaterials, with adjustable elastic properties, offer a promising way to mechanically control stem cells. By designing microstructured bio-metamaterials based on a silicon elastomer-like photoresist and two-photon laser printing, the differential responses of human mesenchymal stem cells (hMSCs) correlate with the calculated elastic properties of the bio-metamaterials, suggesting the potential of using bio-metamaterials for cell behavior regulation.

Summary: This study investigates the combined effects of osteoporosis and diabetes on fracture healing process by developing numerical models. The results show that osteoporotic fractures have higher instability and disruption in mesenchymal stem cells' proliferation and differentiation compared to non-osteoporotic fractures. Moreover, when osteoporosis coexists with diabetes, the healing process of fractures can be severely impaired.

Summary: In this study, titanium carbide was evaluated as a reinforcing additive in polypropylene thermoplastic. The effects of changing the weight percentage of titanium carbide on the characteristics of the nanocomposite material were investigated. The addition of titanium carbide significantly improved the mechanical properties of the polypropylene material.

Summary: This case report describes a probable atypical ulnar fracture associated with denosumab use in a male patient who was treated with teriparatide. The findings suggest that clinicians should be aware of the risk of atypical fractures with anti-resorptive therapy, particularly at non-femur sites.

Summary: In this paper, a model for the mechanical stimulus involved in bone remodeling and its evolution over time is proposed. Numerical simulations show that the model fits well with the time dependency of the adaptive process of bone, indicating its promising potential for further theoretical and experimental investigation.

Summary: Fracture healing is a complex and multistep process highly sensitive to mechanical signals, but challenges in accurately characterizing the mechanical environment and the ever-changing properties of the regenerate have hindered the clear definition of mechanical regulation principles. However, recent advances in using mechanobiological rodent models, imaging approaches, and single-cell analyses are improving our understanding of bone microenvironment response to loading.

Summary: This study investigates the feasibility of delivering full-length PTH using AAV vectors. The results show the ability to secrete full-length PTH from various cell types in vitro and demonstrate the bioactivity of PTH in inducing proliferation in osteosarcoma cell lines. In vivo experiments also show increased liver and plasma concentrations of PTH, as well as dose-dependent changes in tumor growth and blood biomarkers. This proof-of-concept study suggests the potential of AAV gene therapy for hypoparathyroidism.
