The time and cycles to failure were calculated. The data was compared using a Mann-Whitney, Kruskall-Wallis, and Kolmogorov-Smirnov tests, with a significance level of p<0.05.
Results: GT-X files rotated for a significantly longer period of time before
separation occurred, thus GT-X files where more resistant to the Nocodazole ic50 cyclic fatigue compared with ProTaper.
Conclusion: GT-X files have a greater resistance to cyclic fatigue, this fact can be caused by the use of the Ni-Ti alloy “”M-Wire”".”
“Objectives: To compare outcomes after carotid endarterectomy (CEA) with saphenous vein patch closure (SV), with cervical vein (external jugular and common facial) patch closure (CV).
Design: A total of 322 cases of CEA
was achieved consecutively by using venous patch angioplasty. Propensity scores were calculated check details followed by a one-to-one basis case-matching.
Materials: This resulted into 90 SV and 90 CV matched cases.
Methods: The primary endpoint was the incidence of ipsilateral stroke and transient ischaemic attack at any time during follow-up.
Results: Ten-year freedom from stroke was 94.1% +/- 3.5% for the SV group and 90.5% +/- 4.2% for the CV group (log rank P = 0.230). Ten-year freedom from ipsilateral neurological events (stroke and transient ischaemic attack) was 93.5% +/- 3.3% for SV group and 92.4% +/- 3.0% for the CV group (log rank P = 0.403). Ten-year freedom from >= 75% stenosis/occlusion was 93.1 +/- 4.8% for the SV group and 89.9 +/- 6.0% for the CV group (log rank P = 0.481).
Conclusions: CV is a good alternative to SV patching, particularly when the
SV needs to be preserved for further use or is unsuitable. (C) 2011 European Society for Vascular Surgery. Published by Elsevier Ltd. All rights reserved.”
“Complete oocyte lysis in in vitro fertilization (IVF) is a rare event, but one against which we remain helpless. The recurrence of this phenomenon in some women in each of their IVF attempts, regardless of treatment, together with the results of animal experiments led us to investigate the possible involvement of the genes encoding for the glycoproteins constituting the zona pellucida (ZP).
Over BVD-523 the last ten years, during which we treated over 500 women each year, three women suffered recurrent oocyte lysis during their IVF attempts in our Centre for Reproductive Biology. For each of these three cases, we sequenced the four genes and promoter sequences encoding the glycoproteins of the ZP. The sequence variations likely to cause a change in protein expression or structure, were investigated in a control group of 35 women who underwent IVF without oocyte lysis and with normal rates of fertilization.
We found no mutations in the ZP genes sequenced. Only some polymorphisms present in the control group and in the general population were detected, excluding their specific involvement in the phenotype observed.
