SHIELD 500 - PERFORMANCE

Summary of Shield Tests – (November, 2013) 

The Shield is a breakthrough nanotechnology photocatalytic water purification system that uses LEDs to activate powerful chemical reactions that break down, remove, and inactivate contaminants. Water that enters the Shield passes through multiple reaction chambers filled with Puralytics’ solid-state nanotechnology mesh photocatalyst. Light generated by multiple high-powered LEDs saturates each of these reactions chambers, activating the material and treating the water. During treatment, chemical contaminants are mineralized by photo-redox reactions, metals are removed through photo-adsorption, and pathogens are inactivated due to advanced oxidation and direct UV-disinfection. 

 

Tumor M2PK vs. FIT Tests

Abstract 

Introduction Faecal immunochemical tests (FIT) are acceptable to a large part of the general population but used alone are poor at detecting adenomas. An ELISA which measures faecal M2-pyruvate kinase (M2-PK) has been shown to be useful for detecting colonic pathology. 

Aims To prospectively compare M2-PK and FIT in screening for colonic polyps and cancer in the second round of our pilot FIT-based Colorectal cancer screening programme.
