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

open access: yesAdvanced 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 ...

BCG HSP70 Reprograms Macrophages via Central Trained Immunity to Suppress Prostate Cancer

open access: yesAdvanced Science, EarlyView.
BCG‐derived HSP70 (Dnak) safely induces central trained immunity via epigenetic, metabolic, and O‐GlcNAcylation reprogramming of bone marrow progenitors, driving tumor‐associated macrophages toward an M1‐like phenotype to suppress prostate cancer. ABSTRACT Trained immunity offers a promising yet clinically challenging strategy for cancer immunotherapy,

Stapling cartridge lavage cytology in limited resection for pulmonary malignant tumors: assessment of cytological status of the surgical margin

open access: yesHeliyon, 2019
Introduction: Sublobar resection in primary lung cancer and pulmonary metastatic tumor can result in recurrence at the surgical margin. Confirming the absence of tumor cells at the cut-end is important.

Performance Estimation and Ex Vivo Validation of Untethered Magnetic Robots in Soft Tissue

open access: yesAdvanced Science, EarlyView.
This study presents an empirical model that quantitatively predicts the step‐out frequency of screw‐type untethered magnetic robots (UMRs) in soft viscoelastic environments, including ex vivo brain tissue. By integrating key parameters into a dimensionless framework, the model enables estimation of robot performance across a range of biological ...

Locally Advanced Pancreatic Head Cancer: Margin-Positive Resection or Bypass?

open access: yes, 2012
Pancreatic cancer is a highly aggressive disease with poor survival. The only effective therapy offering long-term survival is complete surgical resection.

Is a 3 mm Surgical Margin Safe for Basal Cell Carcinoma in the Head and Neck that is Less than 2 cm, Considering Different Risk Factors?

open access: yesArchives of Plastic Surgery
Background Basal cell carcinoma (BCC) is the most common type of nonmelanoma skin cancer. Typically, resection requires a safety margin of ≥4 mm.

Resectable adenocarcinomas in the pancreatic head: the retroperitoneal resection margin is an independent prognostic factor

open access: yesBMC Cancer, 2008
Background The retroperitoneal margin is frequently microscopically tumour positive in non-curative periampullary adenocarcinoma resections. This margin should be evaluated by serial perpendicular sectioning. The aim of the study was to determine whether

Modification‐Selective Inhibition of Succinate Dehydrogenase a Enables Tumor‐Restricted Mitochondrial Modulation

open access: yesAdvanced Science, EarlyView.
This work identifies acetylation‐dependent SDHA homeostasis as a determinant of tumor‐specific metabolic vulnerability. Guided by this mechanism, a modification‐selective inhibitor, ZPI‐3, selectively targets non‐acetylated SDHA, achieving tumor‐restricted SDH inhibition and effective bladder cancer control. Differential responses in clinical specimens

Carcinoma in situ at the bronchial resection margin: a review. [PDF]

open access: yes, 2011
Carcinoma in situ at the mucosal bronchial resection margin is a rarely reported event. At present, such histological findings at the resection margins are classified as R1(is), thus representing an incomplete resection.
