Review of Gastrointestinal Capsule Robots: Materials, Actuation, Diagnostics, and Therapeutics

Advanced Science, EarlyView.
This review examines gastrointestinal capsule robots through a systems engineering lens, covering shell materials, actuation and localization strategies, diagnostic modalities, therapeutic interventions, and commercialization status. By mapping the complete technological chain from fabrication to clinical deployment, this work identifies critical gaps ...

Targeting CXCR2 in Nociceptive Sensory Neurons Offers Novel Therapeutic Potentials for Postoperative Pain

Advanced Science, EarlyView.
Tissue incision induces CXCL5 release, which activates neuronal CXCR2 on incision‐innervating sensory neurons. Neuronal CXCR2 couples with TRPA1 to drive mechanical pain and engages p38 MAPK signaling to upregulate TRPV1 and promote heat pain. Targeted Cxcr2 knockdown relieves incisional pain while preserving CXCR2‐dependent neutrophil responses ...

Comparison of routinely used intestinal biopsy forceps in dogs: anex vivohistopathological approach

, 2017
ObjectivesTo compare the quality of duodenal and ileal samples obtained with different biopsy forceps. MethodsFifteen dogs were included in a prospective ex vivo study. After euthanasia, the duodenum and the ileum were sampled with four different forceps

An Injectable, Self‐Expanding Hemostatic Foam for Field‐Compatible Postpartum Hemorrhage Management

Advanced Science, EarlyView.
Postpartum hemorrhage is the leading cause of maternal death worldwide, yet many treatments are hard to use outside well‐equipped hospitals. This work introduces an easy‐to‐use device that rapidly delivers a degradable foam into the uterus. The foam stops bleeding through pressure and clotting support, offering a practical option for low‐resource ...

Comparing rectal biopsy using artery forceps and full-thickness rectal biopsy in diagnosing hirschsprung’s disease at University teaching hospital, Lusaka [PDF]

, 2020
Hirschprung’s disease is a congenital disorder that is characterised by functional constipation whose onset is dependent on the length of affected bowel and always involves the rectum. Despite having a diagnostic challenge, rectal biopsy for histological

A Tumor‐Boundary Niche Enriched for PD‐1+CD8+T Cells and BTLA+B Cells Drives Resistance to Immunotherapy in NSCLC

Advanced Science, EarlyView.
A spatial niche composed of BTLA+B cells and CD8+T cells is enriched at the tumor boundary in non‐small cell lung cancer. Within this specialized niche, BTLA+B cells act as a dominant source of IL‐6, upregulating PD‐1 on CD8+T cells via STAT3 signaling.

Immune Biomarkers of Islet Transplant Rejection Revealed by Synthetic Immunological Niche

Advanced Science, EarlyView.
A subcutaneous synthetic immunological niche (IN) enables serial, minimally invasive monitoring of immune responses after islet transplantation. Flow cytometry and transcriptomic profiling of the IN reveal immune‐cell programs associated with graft acceptance and distinct types of rejection.

Adaptive Cellular Responsiveness to Electrical Stimulation at the Skin‐Electrode Interface

Advanced Science, EarlyView.
This study presents an adaptive bioelectronic response in which sustained electrical stimulation (ES) upregulates voltage‐gated calcium channels (VGCCs) and enhances cellular sensitivity to subsequent ES at the skin‐device interface. VGCC‐associated adaptive sensitization promotes regenerative wound‐healing responses in vivo, including accelerated ...
