Immersion Emergencies and Possible Worlds: Engaging Water as Culture and Resource through Contemporary Art

In the present socio-cultural moment, water is increasingly the subject of discussion and contestation in public discourse. As Canadians, we know it as a resource that is ubiquitous within our history and an increasingly desirable international commodity. Our project uses research and practice in visual art to address the subject of water regarding its cultural and environmental importance, linking the historical art practice of picturing nature with the potential of visual representation to offer opportunities for aesthetic and socio-cultural engagement. The project is generously funded by the Social Sciences Research Council of Canada. (see www.immersion-emergencies.ca

Clostridium septicum Empyema in an Immunocompetent Woman

We report a case of a Clostridium septicum empyema in an immunocompetent woman following operation for an incarcerated internal hernia. The patient was successfully treated with pleural decortication and an extended course of postoperative antibiotics. This is the first report of such an infection in the medical literature

Managing Small-scale Fisheries: Alternative Directions and Methods

Human dependence on marine and coastal resources is increasing. Today, small-scale fisheries employ 50 of the world's 51 million fishers, practically all of whom are from developing countries. And together, they produce more than half of the world's annual marine fish catch of 98 million tonnes, supplying most of the fish consumed in the developing world. At the same time, increased fishery overexploitation and habitat degradation are threatening the Earth's coastal and marine resources. Most small-scale fisheries have not been well managed, if they have been managed at all. Existing approaches have failed to constrain fishing capacity or to manage conflict. They have not kept pace with technology or with the driving forces of economics, population growth, demand for food, and poverty. Worldwide, the management and governance of small-scale fisheries is in urgent need of reform. This publication looks beyond the scope of conventional fishery management to alternative concepts, tools, methods, and conservation strategies. There is, for example, broader emphasis on ecosystem management and participatory decision-making. Interested readers will include fishery managers, both governmental and nongovernmental; instructors and students in fishery management; development organizations and practitioners working on small-scale fisheries; and fishers and fishing communities that wish to take responsibility for managing their own resources

Alkaline-Earth Derivatives of Diphenylphosphine-Borane

Treatment of β-diketiminato (BDI = HC{C(CH3)Ndipp)}2 where dipp = 2,6-iPr2C6H3) magnesium butyl [(BDI)MgBu] (I) and calcium hexamethyldisilazide [(BDI)Ca{N(SiMe3)2}] (II) complexes with equimolar quantities of diphenylphosphine-borane, Ph2PH·BH3, results in the formation of the respective alkaline earth (Ae) phosphidoborane derivatives [(BDI)Mg(Ph2PBH3)]2 (6a) and [(BDI)Ca(Ph2PBH3)] (7a). Although satisfactory single crystals of 7a could not be obtained, 6a was crystallographically characterized and both compounds display similar NMR spectra. The dimeric Ae-hydride complexes [(BDI)AeH]2 (IIIa, Ae = Mg; IIIb, Ae = Ca) react with substoichiometric quantities of Ph2PH·BH3, allowing the crystallization of the dimeric Mg and trimeric Ca phosphidoborane species [(BDI)Mg(H)(H3BPPh2)Mg(BDI)] (8) and [{(BDI)Ca}3(H)(H3BPPh2)2] (9). In the absence of coordinating Lewis bases, compounds 6a, 7a, 8, and 9 display dynamic solution-state behavior (in benzene and toluene), while addition of THF furnishes the monomeric adducts [(BDI)Mg(H3BPPh2)·THF] (6b) and [(BDI)Ca(H3BPPh2)·THF] (7b). Addition of Ph2PH·BH3 to compound 6a results in BH3 transfer to eliminate Ph2PH and generate the phosphinodiboronate complex [(BDI)Mg{(H3B)2PPh2}]2 (10) in preference to dehydrocoupling of the phosphidoborane and phosphine-borane reagents.</p

Mycophenolic Acid overcomes imatinib and nilotinib resistance of chronic myeloid leukemia cells by apoptosis or a senescent-like cell cycle arrest.

International audienceWe used K562 cells sensitive or generated resistant to imatinib or nilotinib to investigate their response to mycophenolic acid (MPA). MPA induced DNA damage leading to cell death with a minor contribution of apoptosis, as revealed by annexin V labeling (up to 25%). In contrast, cell cycle arrest and positive staining for senescence-associated β-galactosidase activity were detected for a large cell population (80%). MPA-induced cell death was potentialized by the inhibition of autophagy and this is associated to the upregulation of apoptosis. In contrast, senescence was neither decreased nor abrogated in autophagy deficient K562 cells. Primary CD34 cells from CML patients sensitive or resistant to imatinib or nilotinib respond to MPA although apoptosis is mainly detected. These results show that MPA is an interesting tool to overcome resistance in vitro and in vivo mainly in the evolved phase of the disease
