Effects of 0.2 T static magnetic field on human skin fibroblasts.

Human skin fibroblasts were exposed to 0.2 T static magnetic field generated by a magnetic resonance tomograph. After 1h exposure, cell morphology was modified in association with a concomitant decrease in the expression of some sugar residues of glycoconjugates.

Association between atmospheric ozone levels and damage to human nasal mucosa in Florence, Italy.

We evaluated the effects of urban air pollutants on human nasal mucosa over an 8-month period on 102 subjects living in Florence, Tuscany, Italy. A group of subjects living in a city with a lower level of pollution (Sassari, Sardinia, Italy) was also analyzed. Nasal mucosa cells were harvested by brushing, a noninvasive procedure.

Stomal recurrence following total laryngectomy: clinical and molecular analysis of a series.

The aim of the present study was to analyze the risk features and to discuss the preventive measures and treatment of stomal recurrence (SR) after total laryngectomy (TL), and to investigate the clonal relationship between the primary and recurrent lesions. We reviewed a series of 25 patients affected by SR after TL for laryngeal squamous cell carcinoma. A subset of 7 coupled primary and recurrent carcinomas were examined for microsatellite alterations that were used as a marker of genetic lineage.
