Neonatal and Pediatric Organ Donation: Ethical Perspectives and Implications for Policy [PDF]

, 2015
The lifesaving processes of organ donation and transplantation in neonatology and pediatrics carry important ethical considerations. The medical community must balance the principles of autonomy, nonmaleficence, beneficence, and justice to ensure the ...

Tailoring Vascular‐Immune Homeostasis via Manganese‐DNA Complex‐Armed Immunogenic Extracellular Vesicles for Pancreatic Cancer Immunotherapy

Advanced Science, EarlyView.
This study demonstrates that Mn2⁺–tumor DNA complexes encapsulated in dendritic cell (DC)– derived immunogenic extracellular vesicles (EVDC@Mn‐DNA) act as a DC‐specific cGAS– STING activator. EVDC@Mn‐DNA treatment enhances intratumoral DC activation, improves tumor vascular function, promotes CD8⁺ T cell activity, and suppresses pancreatic tumor growth,

TREM2 Drives Neutrophil Extracellular Traps‐Induced Dendritic Cell Maturation and Contributes to Lupus Progression

Advanced Science, EarlyView.
TREM2 recognizes NETs‐derived MPO to promote DC maturation and antigen presentation, thereby exacerbating the autoimmune response in SLE. Mechanistically, TREM2 activation triggers the DAP12/SYK/ERK cascade and enhances NETs internalization by DCs, which in turn activates the cGAS/STING signaling pathway.

Hyperviscous Diabetic Bone Marrow Niche Impairs BMSCs Osteogenesis via TRPV2‐Mediated Cytoskeletal‐Nuclear Mechanotransduction

Advanced Science, EarlyView.
Diabetic bone marrow exhibits pathological ECM hyperviscosity that activates TRPV2‐mediated Ca2⁺ influx, leading to perinuclear F‐actin disassembly, nuclear deformation, and chromatin condensation. This cytoskeletal‐nuclear decoupling suppresses osteogenic differentiation of BMSCs.

Radial Forearm Free Flap: A Modified Technique for Procurement as a Sentinel Skin Flap

Transplantation Direct
Background. Organ rejection after solid organ transplantation remains a major challenge. The sentinel skin flap (SSF), a vascularized skin flap procured from the donor and transplanted alongside solid organs, has shown promise for early detection of ...

The Tumor‐to‐Endothelial Transfer of FTO Promotes Vascular Remodeling and Metastasis in Nasopharyngeal Carcinoma

Advanced Science, EarlyView.
Integrated omics analysis of matched primary and liver metastatic NPC tumors reveals a unique NOTCH1+ CSC subpopulation exhibiting enhanced stemness properties and tumorigenic capacity. With in vitro and in vivo assays, exosomal transfer of tumor‐derived FTO from NOTCH1+ cells to the endothelium promotes vascular permeability and metastatic potential ...

Endometrial Assembloid Model Reveals Endometrial Gland Development Regulation by Estradiol‐Driven WNT7B Suppression

Advanced Science, EarlyView.
This study developed a 3D endometrial assembloid model to study how uterine glands form and develop. They discovered key interactions between different cell types and identified WNT7B as a regulator controlled by estradiol‐mediated TGFβ1‐VDR interaction.

Hypothermic oxygenated perfusion inhibits CLIP1-mediated TIRAP ubiquitination via TFPI2 to reduce ischemia‒reperfusion injury of the fatty liver

Experimental and Molecular Medicine
The use of fatty livers in liver transplantation has emerged as a crucial strategy to expand the pool of donor livers; however, fatty livers are more sensitive to ischemia‒reperfusion injury (IRI).

Wedelolactone, a Novel TLR2 Agonist, Promotes Neutrophil Differentiation and Ameliorates Neutropenia: A Multi‐Omics Approach to Unravel the Mechanism

Advanced Science, EarlyView.
Wedelolactone (WED), a natural TLR2 agonist, promotes neutrophil differentiation and enhances bactericidal function, offering a potential therapeutic strategy for neutropenia. Using a multi‐omics approach, this study reveals that WED activates the TLR2/MEK/ERK pathway, upregulating key transcription factors (PU.1, CEBPβ) to drive neutrophil development.

Exploring the gender gap in living kidney donation and transplantation- a regional perspective from Punjab, Pakistan

BMC Nephrology
Background Gender disparity remains a significant challenge affecting organ donation and transplantation, as approximately 60% of living kidney transplants performed worldwide involve female donors.
