Real‐Time In Vivo Monitoring of Anastomotic Intestinal Ischemia Using Implantable Resorbable Organic Sensors

open access: yesAdvanced Science, EarlyView.
Resorbable impedance sensors are successfully implanted into porcine small intestinal anastomoses. Impedance was recorded for 2 hours prior, and 2 hours following ischemia induction, and a significant drop in tissue impedance was observed. Abstract Anastomotic failure remains one of the most severe complications in gastrointestinal surgery.

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.

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 ...

Nanoparticle‐Based Tolerogenic Vaccines: Next‐Generation Strategies for Autoimmune and Allergic Disease Therapies

open access: yesAngewandte Chemie, EarlyView.
Nanoparticle‐based tolerogenic vaccines harness controlled antigen delivery and immunomodulation to establish tolerance in autoimmunity and allergy. This review outlines how nanoparticle design (size, shape, composition, administration route) influences biodistribution and immune‐cell targeting.

Engineered Bacteria‐Vesicle Delivered Lactate Reprogramming Boosts Tumor Radiosensitivity

open access: yesAdvanced Science, EarlyView.
We engineered a bacterial‐vesicular dual‐delivery platform that targets LOx to colorectal tumors, enabling lactate clearance, immune microenvironment remodeling, and microbiota modulation. This microbe–metabolism synergistic strategy effectively sensitizes colorectal cancer to radiotherapy, offering a promising approach to overcome radioresistance ...

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.

The features of the human mesenteric lymph node histogenesis in the first half of the prenatal period of ontogenesis

open access: yesZaporožskij Medicinskij Žurnal, 2013
In recent years the important meanings are given to the role of mesenteric lymph node as a peripheral immune organ in the formation of local and general immune reactions. Features of the mesenteric lymph nodes morphogenesis are not well understood due to

Validation of the Safe Application of Tokyo Guideline 2018 (TG18) Severity Grading and Treatment Algorithm in Super‐Elderly Patients Aged 85 and Over With Acute Cholecystitis: A Study in the Japanese Tertiary Care Hospital

open access: yesAnnals of Gastroenterological Surgery, EarlyView.
ABSTRACT Background With population aging and extended healthy life expectancy, the management of acute cholecystitis (AC) in patients aged ≥ 85 years has evolved. However, the Tokyo Guidelines 2018 (TG18) for AC provide no specific risk assessment criteria for this population.
