Serum antibodies to polioviruses in a Tuscan population, Italy
No full textIn order to study the serological status of a population against poliomyelitis, neutralizing antibody for the three types of polioviruses were examined in 742 serum specimens from individuals aged from 1 to 70 years and over were collected during 1985. Sixty-two percent of the sera had antibodies (titre ≥ 1:8) to all three polioviruses, while 5% had no poliovirus antibody at all. However the rates of seropositivity did vary with age: the 10-19 age group had the lowest frequency of antibody (38%) to the three viruses and the difference between the percentage of this group and the previous (1-10 years) and following ones (20-70 years and over) was highly significant. The results of this seroprevalence survey indicate a gap in immunity to poliomyelitis in the population examined

No full textA recombinant Yeast Strain as a short term bioassay to assess estrogen-like activity of xenobiotics
No full textThe study investigated the responsiveness of a recombinant Saccharomyces cerevisiae yeast strain to screen estrogen-like chemicals in order to use it as a first level short-term bioassay for environmental preventive medicine purposes. We used the yeast strain RMY326 ER-ERE, containing the human estrogen receptor alpha and a reporter gene lacZ encoding the enzyme b-galactosidase. We tested the natural steroid hormone 17beta-estradiol, diethylstilbestrol, colchicine, some phytoestrogens and pesticides, and organochlorine insecticides. The relative inductive efficiency (RIE) and EC50 values confirmed the sensitivity and specificity of the yeast strain. A statistically significant reproducibility of results in repeated experiments was assessed
