Bio‐Inspired Micro‐Fin‐Assisted Multi‐Modal Vascular Intervention

open access: yesAdvanced Science, EarlyView.
A magnetic guidewire with a micro‐fin–integrated tip is introduced for multimodal cardiovascular navigation. The micro‐fins exploit fluid drag to augment magnetic torque, enabling bifurcation traversal at 15 mT, tolerating 45° misalignment, bidirectional crawling, and buckle self‐correction.

Gram‐Scale Synthesis of Hafnium‐Rich Carbon Dots for Preclinical Computed Tomography Imaging Across Various Systems

open access: yesAdvanced Science, EarlyView.
Hafnium (Hf)‐rich carbon dots (Hf‐rCDs) with high metal content (40.7%) and robust batch production capacity (>2 g per batch) are synthesized via a facile air‐assisted pyrolysis method. In vivo CT imaging demonstrates outstanding performance of Hf‐rCDs across multiple physiological systems and enables high‐resolution visualization of swine cervical ...

Inferior mesenteric artery revascularization can supplement salvage of mesenteric ischemia

open access: yesJournal of Vascular Surgery Cases and Innovative Techniques, 2023
The inferior mesenteric artery (IMA) has often been overlooked in favor of the celiac or superior mesenteric artery in arterial mesenteric ischemia, owing to the typically robust visceral collateral networks.

BHLHE40 Orchestrates Effector Tissue‐Resident Memory CD8+ T Cells and Limits Long‐Term Survival of Kidney Graft

open access: yesAdvanced Science, EarlyView.
An effector subset of TRM, defined as CD49a+PD1hi CD8+ TRM, represents a BHLHE40‐orchestrated resident immune component that, rather than circulating cells, plays as a major contributor to allograft rejection. ABSTRACT Tissue‐resident memory T cells (TRM), which function against tumors, infections, and non‐self antigens in organ transplantation ...

Two cases of Superior Mesenteric Artery Occlusion in Acute Cerebral Infarction patients with Atrial Fibrillation [PDF]

open access: yesJournal of Neurocritical Care, 2016
Background Acute superior mesenteric artery occlusion is a life-threatening disease that often has nonspecific symptoms. However, it should be suspected in those with known risk factors such as atrial fibrillation, cardiac thrombus or cardiac valvular ...

Learning Curve Effect in Reducing Local Recurrence Rate After Resection of Pancreatic Cancer With Arterial Abutment: A Single‐Center Retrospective Study

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
ABSTRACT Background Pancreatectomy for pancreatic ductal adenocarcinoma (PDAC) with arterial abutment is a complex, high‐risk surgery. We aimed to investigate the clinicopathological features, risk factors, and learning curve for local recurrence after pancreatectomy for PDAC with arterial abutment.

Revising Fascial Anatomy With a Focus on the Fusion Fascia in Mesenteric Gastrointestinal Cancer Surgery

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
This review critically reassesses our prior hypothesis and proposes a revised anatomical model of the fusion fascia that is broadly applicable to GI cancer surgeries grounded in the principles of mesenteric resection. Our synthesis suggests that the fusion fascia is neither a dense connective tissue membrane nor a remnant of mesothelial fusion, but ...

Proposal of Early Drain Exchange After Pancreatoduodenectomy From the View of Reducing Postoperative Pancreatic Fistula

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
ABSTRACT Background To mitigate the progression of postoperative pancreatic fistula (POPF) after pancreatoduodenectomy (PD), appropriate drain management is required, and exchanging drainage tubes is commonly performed. However, the optimal timing of the first drain exchange has not yet been determined.

Prognostic Significance of Portal Vein Tumor Thrombus in Pancreatic Ductal Adenocarcinoma Treated With Chemoradiotherapy

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
ABSTRACT Aim To examine the significance of portal vein tumor thrombus (PVTT) as a prognostic factor for patients with pancreatic ductal adenocarcinoma (PDAC) treated with chemoradiotherapy (CRT) followed by surgery. Methods The study retrospectively examined 313 patients with borderline resectable (BR) or locally advanced (LA) PDAC who underwent CRT ...
