PURPOSE The experiment was performed to prove that exposure to a relatively weak extremely low frequency (ELF) magnetic field retards tadpoles' development. METHODS Two cohorts of Xenopus laevis laevis (Daudin) tadpoles were exposed during their immature period ( approximately 60 days) to a 50 Hz magnetic field of 63.9 < or = B < or = 76.4 microT rms(More)
13 patients with Hodgkin's disease (HD) previously treated, 9 of whom were long-time (more than 2 yr) off-therapy, were studied for peripheral blood lymphocyte response to interleukin 2 and for lymphocyte subpopulations by means of in vitro cultures and monoclonal antibodies. The aim of the study was to ascertain the role played by interleukin 2 in the(More)
To determine the activity of matrix metalloproteinases (MMP), especially MMP-2 and MMP-9, which play an important role in ischemic stroke and intracerebral hemorrhage, we adapted a simple and rapid method for localizing gelatinase activity to a gelatin film in situ-overlay technique previously used in cancer research. Ten micrometer cryosections of rat(More)
Four paediatrics patients affected by Chronic Mucocutaneous Candidiasis associated with hypoparathyroidism have been studied. In vivo and in vitro responses to Candida albicans antigens and to other common antigens (Dermatophytin T, Varidase), the percentage of T and B cells and the response to the selective polyclonal phytomitogens (PHA, ConA, PWM) have(More)
The frequency of 17 HLA antigens from locus A and locus B has been evaluated by microlymphocytotoxicity test in a population of 233 subjects (157 normal and 76 with deficiency of glucose-6-phosphate dehydrogenase [G-6PD]in red cells) from a village of Sardinia, a mediterranean island relatively close to continental Italy. It appears that G-6-PD-deficient(More)
