Calorie restriction extends life span in organisms ranging from yeast to mammals. Here, we report that calorie restriction for either 3 or 12 months induced endothelial nitric oxide synthase (eNOS) expression and 3',5'-cyclic guanosine monophosphate formation in various tissues of male mice. This was accompanied by mitochondrial biogenesis, with increased(More)
OBJECTIVE Cannabinoid type 1 (CB1) receptor is involved in whole-body and cellular energy metabolism. We asked whether CB1 receptor stimulation was able to decrease mitochondrial biogenesis in different metabolically active tissues of obese high-fat diet (HFD)-fed mice. RESEARCH DESIGN AND METHODS The effects of selective CB1 agonist(More)
OBJECTIVE Cannabinoid type 1 (CB1) receptor blockade decreases body weight and adiposity in obese subjects; however, the underlying mechanism is not yet fully understood. Nitric oxide (NO) produced by endothelial NO synthase (eNOS) induces mitochondrial biogenesis and function in adipocytes. This study was undertaken to test whether CB1 receptor blockade(More)
The endocannabinoid system (ECS) plays a critical role in obesity development. The pharmacological blockade of cannabinoid receptor type 1 (CB(1)) has been shown to reduce body weight and to alleviate obesity-related metabolic disorders. An unsolved question is at which anatomical level CB(1) modulates energy balance and the mechanisms involved in its(More)
Nitric oxide (NO) has been postulated to play a role in pain as well as in inflammation. In the present studies, the effects of NO synthase (NOS) inhibitors on both pain and inflammation were examined in a rat model of polyarthritis. Female Lewis rats were injected intraperitoneally (i.p.) with peptidoglycan/polysaccharide (PG/PS) or saline to induce(More)
Immigration is a recent phenomenon, and the most important socioeconomic change that has taken place in Spain in recent years, putting an end to Spain's demographic stagnation and energising its economy. Recent polls indicate that immigration and terrorism are among the main concerns of Spaniards. This paper offers an analysis of the situation of immigrants(More)
The effects of high-potency statins on renal function are controversial. To address the impact of statins on renal morpho-functional aspects, normotensive young mice were treated with rosuvastatin (Rvs). Moreover, because statins may impair mitochondrial function, mice received either dietary supplementation with an amino acid mixture enriched in essential(More)
