Cultivation in a semi‐defined medium of animal infective forms of Trypanosoma brucei, T. equiperdum, T. evansi, T. rhodesiense and T. gambiense.
The cultured trypanosomes had all the characteristics of the in vivo bloodstream forms including: morphology, infectivity, antigenic variation and glucose metabolism. Expand
Mouse alarm pheromone shares structural similarity with predator scents
Chemical analysis in combination with a series of physiological and behavioral tests identify a chemical Leitmotiv that underlies signaling of fear, but also point to a double role for the olfactory Grueneberg ganglion in intraspecies as well as interspecies communication of danger. Expand
Long-Term Effects of Cannabis on Brain Structure
Evidence is provided that regular cannabis use is associated with gray matter volume reduction in the medial temporal cortex, temporal pole, parahippocampal gyrus, insula, and orbitofrontal cortex; these regions are rich in cannabinoid CB1 receptors and functionally associated with motivational, emotional, and affective processing.

Assessment of driving capability through the use of clinical and psychomotor tests in relation to blood cannabinoids levels following oral administration of 20 mg dronabinol or of a cannabis
This controlled clinical study points out the negative influence on fitness to drive after medium or high dose oral THC or dronabinol and identifies a better estimate of impairment than THC alone. Expand
Cannabis and its effects on driving skills.
Although the correlation between blood or oral fluid concentrations and psychoactive effects of THC needs a better understanding, blood sampling has been shown to be the most effective way to evaluate the level of impairment of drivers under the influence of cannabis. Expand
Fatal overdose of tramadol and alprazolam.
A 30-year-old woman, with history of depression, was found dead after the ingestion of an unknown quantity of Xanax (alprazolam), Tramal (tramadol) and alcohol. At the autopsy only a slightExpand
Concentration of drugs in blood of suspected impaired drivers.
Analytical records concerning 440 living drivers suspected of driving under the influence of drug (DUID) were collected and examined during a 2 years period ranging from 2002 to 2003 in canton deExpand
2C-B: a new psychoactive phenylethylamine recently discovered in Ecstasy tablets sold on the Swiss black market.
The amounts of 2C-B found in the tablets were in the range of the minimum quantity required to induce the effects characteristic of this drug. Expand
Codeine accumulation and elimination in larvae, pupae, and imago of the blowfly Lucilia sericata and effects on its development
Results showed that a 29-h interval bias on the evaluation of the larval stage duration calculated from the larvae weight has to be considered if codeine was present in the larvae substrate, which brings new elements regarding the potential use of opiates concentrations in larvae for estimation of drug levels in human tissues.
