The antiphospholipid syndrome (APS) is one of the most encountered autoimmunity in systemic lupus erythematosus (SLE) patients and pathogenesis of these two seems to be intricate. Aim. To investigate the association of antiphospholipid antibodies (APLAs) titer with the presence of secondary APS diagnosis in SLE patients. Methods. 65 patients fulfilling the 2012 Systemic Lupus Collaborating International Clinics (SLICC) SLE's criteria were included. The APS diagnosis was sustained according to the 2006 Sydney APS's criteria. Three groups of patients were defined: SLE patients with secondary APS, SLE with history of positive "criteria" APLAs but without APS clinical features, respectively SLE patients without positive APLAs or clinical APS criteria. An extended APLAs panel was searched in all cases: both IgM and IgG of anticardiolipin antibodies (aCL), anti-β2 glycoprotein I antibodies (aβ2GPI), antiphosphatidylethanolamine antibodies (aPE), antiphosphatidylserine antibodies (aPS), respectively antiprothrombin antibodies (aPT). Results. Only the aβ2GPI, both IgM and IgG serotypes, had significantly higher titers in patients with SLE and secondary APS compared to no APS (with/ without positive APLAs): median (min; max) 7.

Scanning electron microscopy analysis of the deposited films showed that, independent of the fluence, the distribution of the deposited droplets presents two maxima. The first maximum corresponds to the average plume deflection angle value due to the local surface orientation produced by the preferential etching process. The second maximum is observed approximately at 45 • with respect to the normal of the target surface, and is related to the phase explosion products that expand along the incident laser beam direction. The investigation of the twofold distribution of the sub-µm size deposited droplets is important to improve the quality of the deposited coatings.

Authors like Geiger (1986), Levy (2008) and Altbach (1999) made challenging predictions in the 1970s and early 1980s that the private sector would inexorably diminish in size and ...
