Long‐Term Expandable Periosteal Organoids Reconstruct a Functional Regenerative Niche That Support Hematopoietic Stem Cell Maintenance and Bone Repair

open access: yesAdvanced Science, EarlyView.
A robust periosteal organoid system enables long‐term expansion while preserving native cellular heterogeneity. These organoids recapitulate functional niche environments, support hematopoietic stem cell maintenance, and attenuate aging‐associated decline ex vivo.

Adaptive Cellular Responsiveness to Electrical Stimulation at the Skin‐Electrode Interface

open access: yesAdvanced Science, EarlyView.
This study presents an adaptive bioelectronic response in which sustained electrical stimulation (ES) upregulates voltage‐gated calcium channels (VGCCs) and enhances cellular sensitivity to subsequent ES at the skin‐device interface. VGCC‐associated adaptive sensitization promotes regenerative wound‐healing responses in vivo, including accelerated ...

Cerebral Hemodynamic Changes in Older Adults With Cognitive Complaints According to the Presence of Peripheral Artery Disease

open access: yesAGING MEDICINE, EarlyView.
Among 132 older adults, 13 had peripheral artery disease (PAD), identified using the ankle–brachial index. Over approximately 13 months, PAD was associated with increasing middle cerebral artery mean flow velocity, with a significant difference in left‐sided velocity change between groups.

Essential Updates 2024–2026: Advances in Colorectal Cancer Surgery

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
ABSTRACT Surgical innovation in colorectal cancer is increasingly judged not by technical feasibility alone, but by whether it improves oncological outcomes, preserves function, reduces morbidity, or makes difficult procedures more reproducible. This structured narrative review examines major surgical studies published from January 2024 through July ...

Small Intestinal Bacterial Overgrowth Following Gastrointestinal Cancer Surgery: Current Evidence and Future Perspectives

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
ABSTRACT Small intestinal bacterial overgrowth (SIBO) has recently gained increasing attention as a potential cause of postoperative gastrointestinal symptoms following gastrointestinal cancer surgery. Surgical procedures can disrupt normal gastrointestinal physiology through anatomical reconstruction, impaired motility, reduced gastric acid secretion,
