Two-stage combined treatment of leiomyosarcoma of iliac vein using robotic surgery

open access: yesJournal of Vascular Surgery Cases and Innovative Techniques, 2019
Vascular leiomyosarcoma is a rare tumor originating from the vascular smooth muscle cells. Leiomyosarcomas of the external iliac vein are extremely rare. Only single observations of this tumor are reported. We describe a 48-year-old woman who underwent a

Integrated ‘Shield‐Spear’ Biological Patch for Fibrosis‐Free Bladder Reconstruction

open access: yesAdvanced Science, EarlyView.
Fibrosis‐free bladder reconstruction remains challenging. This study pioneers an integrated “shield‐spear” patch: The outer anionic hydrogel layer captures GATA6+ macrophages to suppress collagen overexpression, while the inner S100 aptamer‐engineered EVs target Schwann cells to downregulate the TGFβ/Smad pathway—inhibiting fibrosis with enhanced wound

In Situ Programming of the Tumor Microenvironment to Alleviate Immunosuppression for Pancreatic Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
cmExoaCD11b induced the repolarization of immunosuppressive M2 macrophages into pro‐inflammatory M1 phenotype, thereby promoting the proliferation and activation of CD8+ T cells and reversing the immunosuppressive state of the tumor microenvironment.

Pancreatic Cancer‐Derived Extracellular Vesicles Enriched with miR‐223‐5p Promote Skeletal Muscle Wasting Associated with Cachexia

open access: yesAdvanced Science, EarlyView.
EVs and EV‐microRNAs (miRNAs) mediate PDAC‐skeletal muscle communication. miR‐223‐5p reduces METTL14 transcription by targeting MAFA, which subsequently decreases m6A methylation in skeletal muscles, ultimately leading to muscle wasting. This study highlights the absorption of miRNA in PDAC‐derived EVs by skeletal muscles and reveals a previously ...

BCG‐Derived Outer Membrane Vesicles Induce TLR2‐Dependent Trained Immunity to Protect Against Polymicrobial Sepsis

open access: yesAdvanced Science, EarlyView.
B‐OMVs, nanoscale vesicles derived from BCG, are identified as effective and safe inducers of trained immunity that protect against sepsis. Through TLR2‐mediated metabolic and epigenetic reprogramming of hematopoietic stem cells, B‐OMVs enhance inflammatory response and phagocytic activity.

EFTUD2 Regulates Cortical Morphogenesis via Modulation of Caspase‐3 and Aifm1 Splicing Pathways

open access: yesAdvanced Science, EarlyView.
EFTUD2, a spliceosomal GTPase linked to MFDM, regulates cortical development through apoptotic control. Conditional Eftud2 knockout in murine neural stem cells induces microcephaly and cortical disorganization, while pathogenic variants drive neuronal loss.
