N-Heterocyclic carbenes are now commonly encountered in organometallic and inorganic coordination chemistry. The increasing attention they enjoy is due to their ability to act as ancillary ligands in a growing number of transition metal catalysts or even to play the role of nucleophilic reagents and catalysts in diverse organic transformations. As a fine addition to the NHC-Ru-alkylidenes, popular for their tremendous success in metathesis chemistry, an array of robust and stable Ru-NHCs has proven their utility in non-metathetical reactions. The present review surveys different classes of Ru-NHCs and their applications as efficient catalysts (or precatalysts) in several types of fundamental organic processes e.g. hydrogenation, hydrogen transfer, isomerization, cycloisomerization, cyclopropanation, hydrosilylation, allylation and deallylation, enol-ester synthesis, heterocycle synthesis, C-C alkyne coupling, Kharasch addition and ATRP. A special section is devoted to tandem processes some of which include concurrent or sequential metathesis steps. Relevant mechanistic and stereochemical aspects related to NHC-Ru catalysis will be highlighted. (c) 2006 Elsevier B.V. All rights reserved. [less ▲]

Diabetes mellitus is a chronic disease whose prevalence is increasing worldwide. It remains associated with a high risk of severe complications, essentially micro- and macro-vascular complications. Type 1 diabetes is an auto-immune disease that leads to the destruction of insulin-secreting B cells and therefore requires an intensive optimised exogenous insulin therapy. Type 2 diabetes is a polygenic disease whose expression is favoured by inadequate lifestyle, leading to obesity. It combines a relative insulin secretory defect and insulin resistance, the latter being associated with various other cardiovascular risk factors. Treatment consists of lifestyle modifications first, then the prescription of various glucose-lowering oral drugs and finally, when requested, insulin therapy. A multi-risk intervention is mandatory to improve the cardiovascular prognosis. The prevention of diabetes and its complications is a major public health objective. [less ▲]

This article offers an attempt to redeem Death of a River Guide, the first novel by Richard Flanagan, from readings which see it mainly as an instance of appropriation of Aboriginal culture and spirituality on the part of a white settler writer living in Australia. Indeed, next to its gesturing towards a sense of indigenous belonging in Tasmania, the book displays its affiliation with a more European cultural inheritance, notably through the reference to the work of Italo Svevo and through the inclusion of a rival sense of spirituality, Christian in inspiration. In all, the book's magic realism then incorporates distinct constituents, in a way which points to the critical necessity of subjecting fiction's magic moments to the kind of analysis that will reveal their specific cultural genealogy. Such critical practice would preserve magic realism, as a world-wide literary category, from being used in any levelling, dehistoricized, apolitical manner; and moreover, in the case of Flanagan, it points to an important discursive dialogism which provides an adequate response to the sense of divided epistemology that has characterized Australian literary culture since the Reconciliation.

Insulin secretion and insulin sensitivity interact in concert to maintain glucose homeostasis. Various pathologies, especially type 2 diabetes, are characterized by defects in secretion and/or action of insulin and numerous drugs are able to partially correct these two defects. Therefore, the assessment of insulin secretion and insulin sensitivity is of interest to guide the choice of pharmacological treatments and to evaluate their efficacy. It could be performed by studying the couple of fasting insulin/glucose plasma concentrations or by performing dynamic tests, which mainly use the administration of glucose. The intimate relationship between insulin secretion and insulin sensitivity requires either appropriate tests that open the homeostatic feedback loop ("glucose clamp"), or sophisticated modeling approaches ("HOMA", "minimal model"). Insulin secretion should ideally be measured according to the corresponding insulin sensitivity. Dynamic tests are generally more informative than static measurements in the fasting state. [less ▲]

Significant advances in cardiac surgery include hypothermic circulatory arrest for complex aortic surgery, stentless valve for aortic valvulopathies, conservative treatment of the insufficient aortic valve, surgical interruption of the electrical circuits involved in atrial fibrillation and new extra-corporeal circuits (SMA) to decrease inflammatory systemic reactions, and for, the same reason, heart beating coronary surgery. Advances in vascular surgery include aortic endoprosthesis, coeliscopic aortic surgery and less invasive superficial veins surgery. [less ▲]

Olefin metathesis is a metal-catalysed organic reaction, which involves the statistical redistribution of carbon-carbon double bonds. Since its discovery in the 1950's, this transformation has gained widespread use in research laboratories and industry for making products ranging, from drugs and polymers to enhanced fuels. Its advantages include the ability to build up complex structural scaffolds with remarkable atom economy. Major industrial processes usually rely on inexpensive, ill-defined, multicomponent catalytic systems, while research laboratory applications take advantage of well-defined metal alkylidene complexes of molybdenum and ruthenium that combine high activities and ease of set-up under reproducible conditions, albeit at the price of a higher cost.
