Thymus, 15(4), 223-231 (1990-06-01)
Experimental studies over the last decade have suggested an association between thymus immune and homeostatic function and exogenous tin. It has been hypothesized that the thymus gland synthesizes and secretes one or more tin bearing factors that enhance immune defenses...

Neurotoxicology, 5(2), 129-139 (1984-01-01)
The toxicology of tin is almost entirely the toxicology of the organic compounds of tin, for the metal itself and its inorganic compounds appear to be nearly harmless for practical purposes. Furthermore, the neurotoxicity of organotin is essentially that of...

Ecotoxicology and environmental safety, 56(1), 180-189 (2003-08-14)
This article reviews the literature related to the bioavailability of tin, inorganic tin compounds, and organotin compounds. On the one hand, the toxicity of metallic tin and inorganic tin compounds is low. In aqueous systems, the potential bioavailability of tin...

To evaluate the necessity of three-dimensional imaging (computed tomography [CT]/cone-beam computed tomography [CBCT]) for paramedian insertion of palatal implants. Lateral radiographs and CBCT scans were performed from 18 human skulls. For lateral cephalometry, the nasal floor (right/left) and the oral...
