Osteoporosis under psychological stress: mechanisms and therapeutics.

Psychological stress has been associated with the onset of several diseases, including osteoporosis. However, the underlying pathogenic mechanism remains unknown, and effective therapeutic strategies are still unavailable. Growing evidence suggests that the sympathetic nervous system regulates bone homeostasis and vascular function under psychological stress, as well as the coupling of osteogenesis and angiogenesis in bone development, remodeling, and regeneration.

Effect of rapamycin-eluting stents on in-stent restenosis and early inflammatory response in coronary artery narrowing animal models.

Objective: it was to evaluate the efficacy and safety of rapamycin-eluting stents at different doses in the treatment of coronary artery narrowing in miniature pigs.

Methods: a total of 20 miniature pigs were randomly assigned into four groups: S1 group (low-dose rapamycin-coated stent, 55 µg/mm), S2 group (medium-dose rapamycin-coated stent, 120 µg/mm), S3 group (high-dose rapamycin-coated stent, 415 µg/mm), and D0 group (bare metal stent). The stent size was 3.

Optimizing natural human-derived decellularized tissue materials for periodontal bone defect repair.

Periodontal disease is a major contributor to tooth loss worldwide in adults. Particularly, periodontal bone defect is a common clinical condition, yet current therapeutic strategies exhibit limited effectiveness. Recently, natural bone graft materials have attracted considerable interest for enhancing bone defect repair due to their superior biocompatibility and osteogenic capabilities.

Understanding phage BX-1 resistance in AP-1 and the role of quorum-sensing regulation.

The marine ecosystem is characterized by a rich diversity of bacterial hosts and their phages. The propagation of phages is primarily limited by their ability to adsorb to host cells and is further challenged by various bacterial defense mechanisms. To fully realize the potential of phage therapy in aquaculture, a comprehensive understanding of phage-host interactions and their regulation is essential.

Structural remodeling of the brain cortex and functional recovery following hypoglossal-facial neurorrhaphy in patients with facial paralysis.

Objective: Peripheral nerve injury results in functional alterations of the corresponding active brain areas, which are closely related to functional recovery. Whether such functional plasticity induces relative anatomical structural changes remains to be investigated.

Methods: In this study, we investigated the changes in brain cortical thickness in patients with facial paralysis following neurorrhaphy treatment at different follow-up times.
