Morphodynamics and surgical correction of the body's creases, folds, and wrinkles.

The aesthetics of the human body are a balance of furrows and orifices, and artists of every period have studied the distance between ear and eye, eye and nostrils, nostrils and mouth, nipple and submammary crease, subgluteus folds and iliac crest and so on, to create a code for all body proportions. Currently, the ideal of female beauty prefers more elongated shapes than in the past, and surgical body modeling, performed in accordance with anthropometric rules, uses a combination of techniques to alter the orientation and depth of aesthetic reference points, such as body folds and curves. These must be integrated into the body's biodynamics to both prevent and correct defects and irregularities of the body, which has an inherent disposition to change shape, both because of the physical forces acting on it and because of constant tissue replacement.

In vivo anti-inflammatory effect of statins is mediated by nonsterol mevalonate products.

This study set out to clarify whether the inhibition of sterol or nonsterol derivatives arising from mevalonate biotransformation plays a major role in the in vivo anti-inflammatory action of statins. Hepatic synthesis of all these derivatives was inhibited in mice by administered statins, whereas squalestatin inhibited only sterol derivatives. Using a short-term treatment schedule, we found that statins reduced the hepatic activity of 3-hydroxy-3-methylglutaryl coenzyme A reductase without affecting blood cholesterol.

1,5-Benzodiazepine tricyclic derivatives exerting anti-inflammatory effects in mice by inhibiting interleukin-6 and prostaglandinE(2)production.

The 1,4- and the 1,5-benzodiazepines (BDZ) are commonly used as anxiolytic and anticonvulsive drugs. It has been suggested that they influence, particularly through stimulation of peripheral BDZ receptors, some immune cell properties such as pro-inflammatory cytokine production. The availability of a new class of [1,2,4]triazolo[4,3-a][1,5]benzodiazepine derivatives (compounds IV), endowed with anti-inflammatory and/or analgesic properties but no anti-pentylenetetrazole activity, prompted us to investigate in more detail the anti-inflammatory properties of three selected compounds IV (N,N-dimethyl-1-phenyl-4H-[1,2,4]triazolo[4,3-a][1,5]benz- odiazepin-5-amine; N,N-dibutyl-4H-[1,2,4]triazolo[4,3-a][1,5]benzodiazepin-5-amine; 1-methyl-N,N-dimethyl-4H-[1,2,4]triazolo[4,3-a][1,5]benzodiazepin-5-amine) and one structurally related compound (1-phenyl-4H-[1,2,4]triazolo[4,3-a][1,5]benzodiazepin-5(6H)-one).

Inhibition of monocyte chemotactic protein-1 synthesis by statins.

The beneficial effects of statins on the reduction of cardiovascular events has been partly attributed to their anti-inflammatory properties. In the complex of the different pathogenetic events leading to atherosclerosis, recent data suggest a central role of monocyte chemotactic protein-1 (MCP-1), because mice knock-out for MCP-1 or its receptor CC-chemokine receptor 2 were considerably resistant to plaque formation. In this study we investigated the effect of different statins on in vitro and in vivo production of MCP-1.

Inhibition of HMG-CoA reductase activity by hypercholesterolaemia reduces leukocyte recruitment and MCP-1 production.

To clarify the relationship between cholesterol homeostasis and inflammation we studied the effect of hypercholesterolaemia on in vivo cytokine production and leukocyte migration, in a murine model of local inflammation. Hypercholesterolaemia reduced of 40% the leukocyte recruitment by inhibiting interleukin-6 and monocyte chemotactic protein-1 production in the pouch exudate, without affecting vascular permeability or leukocytes motility.
