A series of images of digestive cancers using Pill Cam COLON2 video capsule endoscopy

Colon capsule endoscopy is regarded as an option to complement or even replace diagnostic colonoscopy in selected cases. Since capsule lacks the capability of taking biopsies, a diagnosis of colon cancer usually requires a further confirmation by colonoscopy. A series of seven patients who had highly suspicious lesions at capsule endoscopy (five-colon tumors, one gastric tumor and one small bowel tumor) and in whom the clinical decision and treatment was solely based on capsule findings, are presented. The diagnosis of cancer was confirmed in all cases by surgery and histology.

CONCLUSION

In selected patients with a high index of clinical suspicion of cancer, PillCam colon 2 capsule endoscopy might be a sufficient tool for diagnosis.

Specific biofunctional performances of the hydroxyapatite-sodium maleate copolymer hybrid coating nanostructures evaluated by in vitro studies

The nanohybrid structures consisting of hydroxyapatite (HA) and sodium maleate-vinyl acetate copolymer (MP) deposited by Matrix Assisted Pulsed Laser Evaporation (MAPLE) technique on Ti surfaces were investigated for specific biological qualities required in bone implantology. The data from in vitro studies demonstrated that human primary osteoblasts (OBs) firmly adhered to Ti coated with HA-MP as indicated by cytoskeleton and vinculin dynamics. OBs spread onto biomaterial surface and formed groups of cells which during their biosynthetic activity expressed OB phenotype specific markers (collagen and non-collagenous proteins) and underwent controlled proliferation.
