A summary of the results is given here. Results observed included compound-related, non-neoplastic lesions of the thyroid in both sexes of rats and mice including follicular cysts and hyperplasia. An increase in the incidence of thyroid neoplasms was observed in the high-dose groups compared to control groups for both sexes of both species.
A thermal printer. Thermal printing (or direct thermal printing) is a digital printing process which produces a printed image by selectively heating coated thermochromic paper, or thermal paper as it is commonly known, when the paper passes over the thermal print head. The coating turns black in the areas where it is heated, producing an image.
In simplest terms, thermal transfer printing utilizes a thermal ribbon and direct thermal printing does not. Thermal transfer involves the thermal print head elements (dots) heating the backside of a thermal transfer ribbon to melt and transfer the compounds on the front side of the ribbon to the label material, thus creating the printed image. Direct thermal printing requires a heat sensitive label material.
