Variation between Pathological Measurement and Endoscopically Estimated Size of Colonic Polyps

GE: Portuguese Journal of Gastroenterology, 2018
Background and Aims: Accurate determination of colonic polyp size is vital to an appropriate surveillance. The main aim of this study was to evaluate variation between the polyp size reported by the endoscopist and its pathological measurement.

Identification of serum protein biomarkers for pre‐cancerous lesions associated with pancreatic ductal adenocarcinoma

Molecular Oncology, EarlyView.
This work identified serum proteins associated with pancreatic epithelial neoplasms (PanINs) and early‐stage PDAC. Proteomics screens assessed genetically engineered mice with abundant PanINs, KPC mice (Lox‐STOP‐Lox‐KrasG12D/+ Lox‐STOP‐Lox‐Trp53R172H/+ Pdx1‐Cre) before PDAC development and also early‐stage PDAC patients (n = 31), compared to benign ...

Clinical management of endoscopically resected pT1 colorectal cancer [PDF]

, 2018
Background Implementation of colorectal cancer (CRC) screening programs increases endoscopic resection of polyps with early invasive CRC (pT1). Risk of lymph node metastasis often leads to additional surgery, but despite guidelines, correct management ...

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...

Photo‐Controlled Antibacterial Drug Release From DASA‐Coated Silica Particles for Improved Treatment of Wound Infections

Advanced Functional Materials, EarlyView.
Synthesis and characterization of light‐responsive donor–acceptor Stenhouse adducts (DASA)‐coated chlorhexidine‐loaded silica nanoparticles. Such a controllable drug‐delivery system enables the release of the antimicrobial drug on demand and in consecutive cycles, thereby maintaining the concentration within the therapeutic window.
