Hydroxyapatite Binding Peptide Lipid Nanoparticles for Biomimetic mRNA Delivery to Bone

Advanced Therapeutics, EarlyView.
Targeted delivery of therapeutic mRNA to peripheral tissues, including bone, is currently challenging. In the current work, a hydroxyapatite binding peptide (HABP) is conjugated to mRNA lipid nanoparticles (LNPs). HABP‐LNPs delivered systemically are demonstrated to reduce transfection in the liver and improve transfection in the femurs of mice ...

Development of the algorithm for differentiating bone metastases and trauma of the ribs in bone scintigraphy and demonstration of visual evidence of the algorithm -- Using only anterior bone scan view of thorax [PDF]

arXiv, 2021
Background: Although there are many studies on the application of artificial intelligence (AI) models to medical imaging, there is no report of an AI model that determines the accumulation of ribs in bone metastases and trauma only using the anterior image of thorax of bone scintigraphy.

Accelerated Bone Healing via Electrical Stimulation

Advanced Science, EarlyView.
Electrical stimulation significantly impacts bone healing by enhancing osteoblast proliferation, differentiation, and vascularization through calmodulin/calcineurin/NFAT signaling. It also boosts macrophage function and cell migration, presenting a comprehensive approach to accelerating bone repair.

Activation of the P2Y2 receptor regulates bone cell function by enhancing ATP release [PDF]

, 2017
Bone cells constitutively release ATP into the extracellular environment where it acts locally via P2 receptors to regulate bone cell function. Whilst P2Y2 receptor stimulation regulates bone mineralisation, the functional effects of this receptor in ...

Targeting Decidual CD16+ Immune Cells with Exosome‐Based Glucocorticoid Nanoparticles for Miscarriage

Advanced Science, EarlyView.
Exosome‐based nanoparticles (GC‐Exo‐CD16Ab) are designed to deliver glucocorticoids (GC) specifically to decidual CD16+ NK cells and macrophages. This targeted delivery effectively suppresses the cytotoxicity of decidual NK cells, inhibits M1 macrophage polarization, and modulates the decidual microenvironment.

Bone Changes With Silicone Chin Implants: Clinical Case, Review, and Considerations for Technique Modification

Plastic and Reconstructive Surgery, Global Open
Background:. Bone resorption has been imputed to silicone chin implants as the cause of the reported bone changes with chin augmentation. Bone remodeling is complex. Both neo-ossification and bone resorption can occur. Methods:.

Tibial Implant Fixation in TKA Worth A Revision? -- How to Avoid Stress-Shielding Even for Stiff Metallic Implants [PDF]

arXiv, 2019
In total knee arthroplasty (TKA) force is transmitted into the tibia by a combined plate-stem device along with cemented or cementless stem fixation. The present work analyzes this force transmission in finite element simulations with the main aim to avoid reported postsurgical bone density reduction as a consequence of a reduced tibial bone loading ...

³H-tetracycline as a proxy for ⁴¹Ca for measuring dietary perturbations of bone resorption [PDF]

, 2007
Our group is interested in evaluating early effects of dietary interventions on bone loss. Postmenopausal women lose bone following reduction in estrogen which leads to increased risk of fracture. Traditional means of monitoring bone loss and effectiveness

Inhibition of Aberrant Activated Fibroblast‐Like Synoviocytes in Rheumatoid Arthritis by Leishmania Peptide via the Regulation of Fatty Acid Synthesis Metabolism

Advanced Science, EarlyView.
LACK156‐173 is internalized into RA‐FLSs via CAPN2‐mediated endocytosis and inhibits the aggressive phenotype of RA‐FLSs by restoring dysregulated fatty acid synthesis metabolism mediated by overexpressed FASN. The findings suggest that targeting the restoration of fatty acid metabolism could potentially alleviate synovial invasion and joint damage in ...

Perawatan Ortodonti pada Kasus Mutilasi dengan Resorpsi Tulang Alveolar dan Resesi Gingiva (Laporan Kasus)

Journal of Dentistry Indonesia, 2015
In the mutilated case in adults, generally malocclusion is often accompanied by less support of periodontal tissues, such as alveolar bone resorption and gingival recession. The treatment of orthodontic is to arrange the teeth into good position and good
