Objective. Articular deposition of monosodium urate monohydrate (MSU) crystals may promote cartilage and bone erosion. Therefore, the aim of this study was to determine how MSU crystals stimulate chondrocytes. Conclusion. In chondrocytes, MSU crystals activate a signaling kinase cascade typically employed by adhesion receptors that involves upstream Src and FAK family activation and downstream p38 activation. In this cascade, Pyk-2, Src, and p38 kinases transduce MSU-induced NO production and MMP-3 expression. Our results identify Pyk-2 and c-Src as novel sites for potential therapeutic intervention in cartilage degradation in chronic gout.

“…According to desorption isotherms and the calculated desorption equilibrium constant of 2.35×10 -3 25 o C [9], the optimized partial pressure of desorbed CO 2 is 1.6 kPa at a regeneration efficiency of 12.8%. For direct integration to fuel synthesis, the low pressure CO 2 with saturated vapor (CO 2 and then compressed to 100 kPa. For separated fuel synthesis, the low pressure CO 2 will be compressed to liquid after the water vapor has been removed by a condenser ( Figure 4).…”

Synthetic hydrocarbon fuel, derived from renewable energy and captured carbon dioxide from flue gas and/or ambient air, can close its carbon cycle and is an important approach to sustainable energy. In this study, the thermodynamic performance of a coelectrolysis process for producing hydrogen and carbon monoxide from water and captured CO 2 is investigated, based on current carbon capture and high-temperature electrolysis technologies. The exergy analysis is useful because it can reveal the energy losses due to irreversibilities and indicate possibilities for improvement of a process. Fuel synthesis systems integrated with or separated from different carbon capture technologies were evaluated and the analysis results have indicated that compared to the energy/exergy consumed by electrolysis, the energy/exergy penalty from CO 2 capture is insignificant. The thermodynamic efficiency of fuel synthesis could be increased by developing fuel generation technologies with lower electricity requirements, especially when using solar and nuclear energy.

“…5 The carbonation reaction was also applied to coal gasification gases in the acceptor gasification process. 6 Recently, a number of power plant concepts [7][8][9] with near zero emissions were proposed to produce H 2 , and/or electricity from fossil fuels by integrating CO 2 separation, based on the carbonation reaction of CaO. In the sorption enhanced methane steam reforming process, the addition of a Ca-based sorbent to the reforming reactor can remove selectively CO 2 from the products, thereby shifting the equilibrium of reforming reactions, and resulting in process simplification, improved energy efficiency, and increased reactant conversion and product yield.…”

in Wiley InterScience (www.interscience.wiley.com).Process analysis of CO 2 capture from flue gas using Ca-based carbonation/calcination cycles is presented here. A carbonation/calcination system is composed essentially of two reactors (an absorber and a regenerator) with Ca-based sorbent circulating between the two reactors (assumed here as fluidized beds). CO 2 is, therefore, transferred from the absorber to the regenerator. Because of the endothermicity of the calcination reaction, a certain amount of coal is burned with pure oxygen in the regenerator. Detailed mass balance, heat balance and cost of electricity and CO 2 mitigation for the carbonation/calcination cycles with three Ca-based sorbents in dual fluidized beds were calculated and analyzed to study the effect of the Ca-based sorbent activity decay on CO 2 capture from flue gas. The three sorbents considered were: limestone, dolomite and CaO/Ca 12 Al 14 O 33 (75/25 wt %) sorbent. All results, including the amount of coal and oxygen required, are presented with respect to the difference in calcium oxide conversion between the absorber and the regenerator, which is an important design parameter. Finally, costs of electricity and CO 2 mitigation costs using carbonation/calcination cycles for the three sorbents were estimated. The results indicate that the economics of the carbonation/calcination process compare favorably with competing technologies for capturing CO 2 .A more detailed description of the process, with the notation given in Figure 2.
