Coronary disease identification using the discriminant analysis

Summary This paper presents a method for identification of coronary disease using the discriminant analysis. The set of discriminant variables used is composed by the general characteristics of the patient, the lipemic values, collected by a blood analysis, and some results of a cardiac catheterism. By using all the variables a total level of classification of about 89.9% is reached, separating the healthy patients from the sick patients affected by a coronary disease. The discriminant analysis is also performed using the general characteristics of the patient and the lipemic values only (i.e. noninvasive medical examinations), and general characteristics and some results of a cardiac catheterism only. In conclusion, the diagnosis of coronary artery disease, obtained by discriminant analysis of noninvasive data, seems to be good enough to discriminate sick from healthy people and to assign patients to a further protocol.

ELISA and LC-MS/MS methods for determining cyanobacterial toxins in blue-green algae food supplements

The use of natural products as a diet supplement is increasing worldwide but sometimes is not followed by adequate sanitary controls and analyses. Twenty samples of pills and capsules of lyophilised cyanobacteria (blue-green algae), commercialised in Italy as dietary supplements, were found positive at the Vibrio fischeri bioassay. Further analyses with ELISA and LC-MS/MS methods revealed the presence of four microcystin (MC) analogues, MC-LR, -YR, -LA, -RR and two demethylated forms of MC-RR. The highest total microcystin content was 4.5 and 1.4 microg g-1 in pills and capsules, respectively. The ELISA measurements, compared to the LC-MS/MS analyses, showed significantly lower concentrations of microcystins in pills, this confirming a possible ELISA underestimate of mixed microcystins, due to different sensitivities for some toxic analogues.
