Type 2 diabetes is closely related to abdominal obesity and is generally associated with other cardiometabolic risk factors, resulting in a high incidence of cardiovascular complications. Several animal and human observations suggest that the endocannabinoid (EC) system is overactivated in presence of abdominal obesity and/or diabetes, and contributes to disturbances of energy balance and metabolism. Not only it regulates the intake of nutrients through central mechanisms located within the hypothalamus and limbic area, but it also intervenes in transport, metabolism and deposit of the nutrients in the digestive tract, liver, adipose tissue, skeletal muscle, and possibly pancreas. Activation of both central and peripheral CB1 receptors promotes weight gain and associated metabolic changes. Conversely, rimonabant, the first selective CB(1) receptor antagonist in clinical use, has been shown to reduce body weight, waist circumference, triglycerides, blood pressure, insulin resistance and C-reactive protein levels, and to increase HDL cholesterol and adiponectin concentrations in both non-diabetic and diabetic overweight/obese patients. In addition, a 0.5-0.7% reduction in glycated hemoglobin (HbA1c) levels was observed in metformin- or sulfonylurea-treated patients with type 2 diabetes and in drug-naive or insulin-treated diabetic patients. Almost half of metabolic changes occurred beyond weight loss, in agreement with direct peripheral effects. Rimonabant was generally well-tolerated, but with a slightly higher incidence of depressed mood disorders, anxiety, nausea and dizziness compared to placebo. New trials are supposed to confirm the potential role of rimonabant (and other CB1 neutral antagonists or inverse agonists) in overweight/obese patients with type 2 diabetes and high risk cardiovascular disease.

The case of a 60-year-old male presenting fever of recent onset is reported. He had undergone a Bentall operation seven yeasr previously. An infective endocarditis caused by Entercoccus Faecalis was detected on his prosthetic valve. After a favorable evolution under antibiotic treatment, the patient developed a perivalvular abscess requiring surgical treatment. The patient's evolution was satisfactory. Diagnosis, with the specific role of echocardiography; treatment, with a recall of surgical indications; particularities of the specific complication and prevention of this pathology are discussed.

Isolated tricuspid valve endocarditis is the least common endocarditis with an incidence of 5 to 10% in the literature. It is usually described in drug abusers and as a complication of nosocomial infections (catheter, post-surgery...). We present the case of a 70 year-old patient admitted for a fever of unknown origin lasting for 2 months. He had an isolated tricuspid endocarditis with Enterococcus faecalis. We review the diagnostic criterias predisposing factors and treatment of right-sided valvular endocarditis, particularly the endocarditis produced by Enterococcus faecalis, a rare etiopathogenic agent of tricuspid endocarditis.

Energy homeostasis (balance) depends on the relationship between the amount of consumed feed energy and energy expenditure. Coordination of energy expenditure and feed intake (appetite) is necessary for the regulation of body composition. The hypothalamus integrates peripheral and central signals to generate satiety or hunger. Birds and mammals utilize common signaling molecules but some molecules possess different/opposite functions. If relevant, particular differences with the mammalian regulatory system are highlighted in this review. For example, obestatin had no significant effect on feed intake of chicks, but it was claimed to decrease food intake in mammalian species. Ghrelin displayed appetite-stimulating effects in mammals but appetite-decreasing effects in birds. Recently, the function of the hypothalamic AMPK signaling pathway on feed intake regulation has received considerable attention in poultry. Alpha-lipoic acid might exert its appetite-decreasing effect by the AMPK signaling pathway. This review discusses the central regulation of energy homeostasis, role of (an)orexigenic peptides, effect of feed deprivation on hypothalamic neuropeptide gene expression and provides a model for involvement of AMPK in the regulation of avian energy balance.

Analyses of the development of the reproductive system in seasonally breeding birds in the framework of long-term ecological studies are rare. Here, we present the first results of such a study in two Corsican populations of a European passerine bird, the blue tit (Parus caeruleus). The two study populations occupy different oak habitats and are separated by only 25 km. Despite their close proximity, they show a one-month difference in onset of egg laying, even after controlling for altitude. This micro-geographic difference in breeding date appears adaptive because both study populations raise chicks when food is most plentiful. In our study, males reached their maximum song activity during the egg-laying stage while maximal testosterone levels and testes sizes were reached 2-3 weeks before egg laying. The rate of development of the reproductive system in males was much faster in the earlier population, in spite of a similar onset of gonad development and song activity for the two study populations. No change in the volume of the song-control nuclei (HVC and RA) could be detected during the study period. Development of brain nuclei was completed 2-3 months before the beginning of intense sexual activity. (C) 2004 Elsevier Inc. All rights reserved. [less ▲]

The mycotoxin zearalenone (ZEN) is a secondary metabolite of fungi which is produced by certain species of the genus Fusarium and can occur in cereals and other plant products. Reporter gene assays incorporating natural steroid receptors and the H295R steroidogenesis assay have been implemented to assess the endocrine disrupting activity of ZEN and its metabolites alpha-zearalenol (alpha-ZOL) and beta-zearalenol (beta-ZOL). alpha-ZOL exhibited the strongest estrogenic potency (EC(50) 0.022+/-0.001 nM), slightly less potent than 17-beta estradiol (EC(50) 0.015+/-0.002 nM). ZEN was ~70 times less potent than alpha-ZOL and twice as potent as beta-ZOL. Binding of progesterone to the progestagen receptor was shown to be synergistically increased in the presence of ZEN, alpha-ZOL or beta-ZOL. ZEN, alpha-ZOL or beta-ZOL increased production of progesterone, estradiol, testosterone and cortisol hormones in the H295R steroidogenesis assay, with peak productions at 10 muM. At 100 muM, cell viability decreased and levels of hormones were significantly reduced except for progesterone. beta-ZOL increased estradiol concentrations more than alpha-ZOL or ZEN, with a maximum effect at 10 muM, with beta-ZOL (562+/-59 pg/ml)>alpha-ZOL (494+/-60 pg/ml)>ZEN (375+/-43 pg/ml). The results indicate that ZEN and its metabolites can act as potential endocrine disruptors at the level of nuclear receptor signalling and by altering hormone production. [less ▲]

Several scientific studies revealed that substances with hormonal (or antihormonal) activity are widely distributed in the environment as well as in food, either as natural constituents (as phytoestrogens), or as substances of anthropogenic origin (for example, Several observations concerning both the wild fauna and humans indicate that these products with hormonal activity are endocrine disruptors. Numerous ecotoxicological studies evidenced important disturbances of the fertility of the wild fauna in zones contaminated by pesticides. In humans, epidemiological studies revealed a significant increase of certain cancers (among others, that of the testicles) and a decrease of the male fertility. Substances with estrogenic activity are often considered, but other hormonal effects are more and more frequently discovered (i.e. anti-androgenic). Numerous worries appear concerning the long-term effects on human health linked to a chronic exposure to these substances by food ingestion. It is urgent to review, not only on the actual contamination of our food by endocrine disruptors (in terms of identification and quantification of every individual chemical), but also the potentially toxic activity of food containing a mixture of contaminants present at levels below their individual toxicity threshold.
