Valproic Acid Inhibits Ferroptosis and Improves Bone Integration in OVX Rats Through the AMPK/SIRT1 Pathway

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT The prevalence of postmenopausal osteoporosis (PMOP) has been steadily increasing. Ferroptosis has been recognized as a critical factor influencing the bone‐forming ability of bone marrow mesenchymal stem cells (BMSCs). Valproic acid (VPA), an HDAC inhibitor, has been suggested to play a role in regulating osteoporosis development; however ...

Combined Effects of Puerarin and Adipose‐Derived Stem Cells on Alveolar Bone Preservation and Inflammation Control in Periodontitis Through p38MAPK Modulation

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This study evaluated the effects of puerarin and adipose‐derived stem cells (ADSCs), alone or combined, on p38MAPK activity, alveolar bone preservation, and inflammatory responses in a rat periodontitis (PD) model and in vitro. ADSCs were exposed to various puerarin concentrations to assess cell proliferation, osteogenic differentiation, and ...

Mechanical Properties and Testing Strategies for Two‐Photon Lithography: A Review of Current Practices and Emerging Challenges

Laser &Photonics Reviews, EarlyView.
Two‐photon lithography enables the fabrication of complex 3D microstructures with tunable mechanical properties spanning from soft hydrogels to rigid hybrid networks. This review summarizes how material composition, printing parameters, and post‐processing govern stiffness and viscoelasticity, highlighting advanced characterization methods and emerging

Ultrasound Measurements, Physico‐Chemical Characterization and Biological Evaluation of Magnesium Hydroxyapatite for Biomedical Applications

Macromolecular Symposia, EarlyView.
ABSTRACT In this study, 15MgHAp (xMg = 0.15) was synthesized by an adapted method, lyophilized, and characterized to evaluate its physicochemical and biological properties. The ultrasound measurements (US) evaluated the stability of the resulting MgHAp gel. Complementary surface information was obtained using a scanning ultrasonic microscope (SUM). The

Ultrasound Evaluation and Biological Assessment of Zinc‐Doped Hydroxyapatite for Antimicrobial Applications

Macromolecular Symposia, EarlyView.
ABSTRACT In this study, undoped and zinc‐doped hydroxyapatite (xZn = 0; 0.4; H‐LF and 4ZH‐LF) were synthesized by an adapted method (and dried by lyophilization) and characterized through a series of analytical techniques in order to evaluate their stability, morphological, and biological properties.
