The paper discusses the paradigm of singular quantifiers in Italian (qualche, ogni, qualsiasi, etc.), focusing on the syntactic and semantic properties of the existential qualche. In different domains, qualche seems to correspond to the English a few, one or more, some or other. The analysis tries to derive the polisemy of this expression from two distinct positions of interpretation, a basic logical meaning and the effect of pragmatic scales. Qualche is then contrasted with English some, Spanish algun and Italian qualsiasi. In the second part of the article the theory is tested against the scope possibilities of qualche, and the quantificational status of this indefinite is evaluated.

The 4G/5G plasminogen activator inhibitor-1 (PAI-1) promoter polymorphism has been associated with basal PAI-1 levels, with ischemic heart disease, and with adverse prognosis in critically ill patients. We hypothesized it might also influence the acute-phase levels of PAI-1 following coronary bypass surgery.In 111 consecutive patients undergoing elective coronary bypass surgery, 4G/5G genotyping and serial plasma PAI-1 activity and antigen levels were prospectively measured before surgery, daily up to 72 h, and at discharge. The inflammatory reaction was additionally assessed by white cell count, fibrinogen, interleukin-6, and C-reactive protein levels.PAI-1 activity and antigen concentrations increased approximately two-fold after surgery, peaking at 48 hours. Carriers of the 4G-allele, compared with 5G/5G homozygotes, showed approximately 20% higher PAI-1 activity and antigen both preoperatively ( P = 0.007 and P = 0.035) and after surgery. White cell count, fibrinogen, interleukin-6, and C-reactive protein values did not differ significantly according to genotypic groups. In multivariate analysis, the 4G/5G genotype was the only significant modulator of postoperative PAI-1 activity (P = 0.003) and the main significant modulator of postoperative PAI-1 antigen (P = 0.013). No significant interaction was found between the effects of time and genotype on postoperative PAI-1. This indicates that the association between 4G/5G and acute-phase PAI-1 levels is secondary to the genotype-related difference of baseline PAI-1.Postoperative PAI-1 concentrations of patients undergoing elective coronary bypass surgery are higher in carriers of the 4G-allele than in 5G/5G homozygotes as a result of higher baseline values. Knowledge of 4G/5G status may be useful to predict acute-phase PAI-1 concentrations.
