We describe the molecular mechanisms of action of nicotine and delta 9-tetrahydrocannabinol, the most potent component of cannabis. Like other drugs of abuse, these compounds enhance dopamine release in a precise area of the limbic system when administered acutely. It has recently been shown that the cannabinoid receptors on which delta 9-tetrahydrocannabinol acts are also activated by endogenous ligands such as anandamide. This unconventional neurotransmitter appears to have important physiological effects in the central nervous system. Both preclinical and clinical evidence suggests that nicotine is more addictive than delta 9-tetrahydrocannabinol. However, the intimate interactions that exist between cannabinoid and opioid systems within the brain suggest that cannabinoids should not be considered as harmless drugs of abuse. [less ▲]

An original image analysis method is presented to characterize multi-walled carbon nanotubes from transmission electron microscopy images. The analysis is performed in three steps: (i) image preprocessing in order to isolate the nanotubes from the background, (ii) image segmentation, aiming at keeping only the measurable sections of nanotubes, and finally (iii) tube characteristics measurement. The measurement is based on a Lambert-like electron absorption law and is performed on the original gray level image itself. Two geometrical and one physical characteristics are determined for each tube, namely, its outer and inner radius and a linear electron absorption coefficient. The method is illustrated by comparing a pristine and an annealed carbon nanotube samples. The compaction of the tube walls during annealing is shown to result from a lowering of the external radius while the inner radius is left unchanged. (C) 2003 Elsevier Ltd. All rights reserved.
