There were no significant differences in JOA score

There were no significant differences in JOA score GSK J4 clinical trial at the latest follow-up among patients with LSS, DS, and degenerative scoliosis (22.3 +/- 5.3, 23.3 +/- 4.4, and 21.6 +/- 2.6, respectively). Four patients (7%) underwent reoperation; 2 had DS and 2 had DLS. The preoperative percentages of slippage in patients with LSS, DS, and DLS were 0.4% +/- 2.2%, 13.2% +/- 5.9%, and 0.0% +/- 1.3%, respectively, whereas degrees of progression of slippage at latest follow-up were 1.2% +/- 3.1%,

2.4% +/- 4.7%, and 0.0% + 0.0%, respectively. There were no significant differences in progression of slippage among these 3 disease groups.

Conclusion. Microsurgical bilateral decompression via a unilateral approach is a minimally invasive technique that yielded satisfactory surgical outcomes even on minimum 5-year follow-up.”
“The typical fungal membrane component ergosterol was previously shown to trigger defence responses and protect plants against pathogens. Most of the elicitors mobilize the second messenger calcium, to trigger plant defences. We checked

the involvement of calcium in response to ergosterol using Nicotiana plumbaginifolia and Nicotiana tabacum cv Xanthi cells expressing apoaequorin in the cytosol. First, it was verified if ergosterol was efficient PLX3397 in vitro in these cells inducing modifications of proton fluxes and increased expression of defence-related genes. Then, it was shown that ergosterol induced a rapid and transient biphasic increase of free [Ca2+](cyt)

which intensity depends on ergosterol concentration Cell Cycle inhibitor in the range 0.002-10 mu M. Among sterols, this calcium mobilization was specific for ergosterol and, ergosterol-induced pH and [Ca2+](cyt) changes were specifically desensitized after two subsequent applications of ergosterol. Specific modulators allowed elucidating some events in the signalling pathway triggered by ergosterol. The action of BAPTA, LaCl3, nifedipine, verapamil, neomycin, U73122 and ruthenium red suggested that the first phase was linked to calcium influx from external medium which subsequently triggered the second phase linked to calcium release from internal stores. The calcium influx and the [Ca2+](cyt) increase depended on upstream protein phosphorylation. The extracellular alkalinization and ROS production depended on calcium influx but, the ergosterol-induced MAPK activation was calcium-independent. ROS were not involved in cytosolic calcium rise as described in other models, indicating that ROS do not systematically participate in the amplification of calcium signalling. Interestingly, ergosterol-induced ROS production is not linked to cell death and ergosterol does not induce any calcium elevation in the nucleus. (C) 2011 Elsevier Masson SAS. All rights reserved.
