Lithium‐Doped Hydroxyapatite Nanowires Rejuvenate Senescent Macrophages Via the Lysosome‐Dependent Ferroptosis Axis to Promote Aged Bone Regeneration

Advanced Science, EarlyView.
Li‐nHAP+GelMA promotes mandibular bone regeneration in aged mice by remodeling the senescent immune microenvironment. Local delivery of Li‐nHAP restores lysosomal homeostasis in senescent macrophages, reduces intracellular labile Fe2+ accumulation, ROS production, and lipid peroxidation, thereby suppressing macrophage ferroptosis and senescence ...

Iatrogenic Femoral Arteriovenous Fistula with Double Connection between Femoral Artery and Vein Leading to High-Output Heart Failure Years after Mitral and Tricuspid Valve Replacement

Case Reports in Vascular Medicine, 2013
Arteriovenous fistulas (AVFs) are potentially harmful but curable complications of diagnostic and interventional cardiac catheterizations. In this report, we present a case of iatrogenic AVF both from superficial and deep femoral arteries to common ...

CaMKIIδ Phosphorylates AUP1 to Promote Pancreatic Tissue Repair and Acinar‐to‐Ductal Metaplasia Formation via Mediating PERK‐Dependent Unfolded Protein Responses

Advanced Science, EarlyView.
CaMKIIδ–AUP1 signaling maintains PERK‐dependent ER homeostasis during ADM‐mediated pancreatic repair. ABSTRACT Pancreatic repair after acute pancreatitis (AP) is essential for restoring tissue integrity, but the intrinsic mechanisms coordinating acinar plasticity and regeneration remain poorly understood.

BRCA1 Mutation‐Recognizing Tetrahedral Framework Nucleic Acid Nanoplatform Enables Coordinated PARP/WEE1 Inhibition and STING‐Associated Antitumor Immunity in Ovarian Cancer

Advanced Science, EarlyView.
BRCA1 mutation‐responsive FBOA‐tFNA selectively recognizes mutant transcripts and coordinates reduction‐responsive intracellular delivery of olaparib and adavosertib, amplifying DNA damage and weakening G2/M checkpoint protection. These effects are accompanied by STING‐associated immune activation and stronger antitumor immunity, while sequential anti ...

Lactate Homeostasis Disruption Potentiates TACE‐Immunotherapy in Hepatocellular Carcinoma

Advanced Science, EarlyView.
Lactate homeostasis is disrupted through spatially coordinated extracellular neutralization and intracellular acidification, triggering calcium overload, mitochondrial dysfunction, and immunogenic cell death. This metabolic reprogramming alleviates the immunosuppressive tumor microenvironment and enhances immune checkpoint blockade, providing a ...

Rational Surface Engineering Reduces Advanced Glycation End‐Product Adsorption and Improves Implant Integration

Advanced Science, EarlyView.
Targeted surface chemical modification prevents the accumulation of advanced glycation end products (AGEs) on implant surfaces, attenuates inflammation and fibrosis, effectively restores angiogenic activity, and improves osseointegration under diabetic conditions.

DUSP26 Regulated by YY1 Lactylation Couples Osteogenesis and Angiogenesis by Dephosphorylating PMPCB at Y141 and Activating Mitophagy in BMSCs

Advanced Science, EarlyView.
p300‐associated YY1 lactylation promotes DUSP26 expression in BMSCs. By regulating PMPCB phosphorylation and PINK1 processing, DUSP26 supports mitophagy, osteogenic differentiation, and pro‐angiogenic factor secretion. BMSC‐derived exosomes carrying a RUNX2 promoter‐driven DUSP26 plasmid favor osteogenic‐lineage transgene expression, partially ...

Non‐Canonical Function of DDX21 in Fetal Hematopoiesis Antagonizes KDM5A‐Mediated Repression of Ribosomal and Hematopoietic Genes

Advanced Science, EarlyView.
This study demonstrates a mechanism by which RNA helicase DDX21 coordinates the transcription of hematopoietic and ribosomal genes by interacting with the H3K4me3 demethylase KDM5A. The DDX21‐KDM5A complex co‐occupies active genes in hematopoietic progenitors, thereby ensuring their rapid proliferation during fetal hematopoiesis.

A Bi‐Adjuvant Senolytic Nanovaccine Modulating Dendritic Cell Senescence Ameliorates Aging‐Related Metabolic Dysfunction

Advanced Science, EarlyView.
An active biomaterial‐based bi‐adjuvant nanovaccine restores the immunocompetence of aged dendritic cells to overcome senescent cell tolerance. Accompanied by the downregulation of mitotic kinases Aurka/b and attenuation of senescence‐associated PI3K/AKT phosphorylation, the nanovaccine enhances antigen‐presenting capacity and promotes potent cytotoxic

Deep Venous Thrombosis Within a Complete Duplication of the Left Femoral Vein

Cureus
Venous duplications, particularly in the femoral vein, are rare anatomical variations that can complicate the clinical presentation and management of deep venous thrombosis (DVT). This case describes an elderly female who was diagnosed by her primary care physician with a left lower extremity DVT one week prior to her presentation and had been ...
