Recent studies suggest that the endocannabinoid system modulates feeding. Despite the existence of central mechanisms for the regulation of food intake by endocannabinoids, evidence indicates that peripheral mechanisms may also exist. To test this hypothesis, we investigated (1) the effects of feeding on intestinal anandamide accumulation; (2) the effects(More)
In the mammalian host, African trypanosomes generate consecutive waves of parasitaemia by changing their antigenic coat. Because this coat consists of a single type of variant surface glycoprotein (VSG), the question arises of how a trypanosome accomplishes the transcription of only one of a multi-allelic family of VSG expression site loci to display a(More)
The endocannabinoid system is involved in a variety of effects of drugs of misuse, and blockade of the cannabinoid CB1 receptor by selective antagonists elicits marked reductions in opioid and alcohol self-administration. The present study was designed to extend our knowledge of the role of the cannabinoid CB1 receptor in the modulation of alcohol misuse(More)
The present study evaluates the pharmacological profile of the new neutral cannabinoid CB1 receptor antagonist 5-(4-chlorophenyl)-1-(2,4-dichlorophenyl)-3-hexyl-1H-1,2,4-triazole -LH-21- on feeding behavior and alcohol self-administration in rats, two behaviors inhibited by cannabinoid CB1 receptor antagonists. Administration of LH-21 (0.03, 0.3 and 3(More)
The endogenous cannabinoid acylethanolamide AEA (arachidonoylethanolamide; also known as anandamide) participates in the neuroadaptations associated with chronic ethanol exposure. However, no studies have described the acute actions of ethanol on AEA production and degradation. In the present study, we investigated the time course of the effects of the(More)
New inert materials such as polymerized silicones, Bioplastique, Artecoll, and Dermalive are now being used as injectable aesthetic microimplants. These substances are better than the old ones because they tend not to migrate and do not usually produce much of a host immune response. Adverse reactions after injection of these materials are rare, although(More)
Alcoholism is characterized by successive relapses. Recent data have shown a cross-talk between the cannabinoid system and ethanol. In this study, male Wistar rats with a limited (30 min sessions), intermittent, and extended background of alcohol operant self-administration were used. The relapse to alcohol after 1 week of alcohol deprivation was evaluated.(More)
More than 20 years ago, biochemical analysis of the eukaryotic cell cytoskeleton revealed the major component proteins. The heterodimeric (α/β) protein tubulin was defined as the building block of microtubules, assembled in a polar manner into specifically arranged protofilaments in the microtubule wall [1]. The next two members of the tubulin protein(More)
3,4-Methylenedioxymethamphetamine (MDMA) produces acute dopamine and 5-HT release in rat brain and a hyperthermic response, which is dependent on the ambient room temperature in which the animal is housed. We examined the effect of ambient room temperature (20 and 30 degrees C) on MDMA-induced dopamine and 5-HT efflux in the striatum and shell of nucleus(More)
BACKGROUND Studies indicate that adjuvant 5-fluorouracil (5-FU) with folinic acid (FA) in colorectal cancer patients with completely resectable liver-limited metastases (LMCRC) offers clinical benefit over surgery alone. This phase III trial compared FOLFIRI with simplified 5-FU/FA in this setting. PATIENTS AND METHODS LMCRC patients were randomized to(More)
