VOC 202012/01 Variant Is Effectively Neutralized by Antibodies Produced by Patients Infected before Its Diffusion in Italy.

The coronavirus disease 2019 (Covid-19) pandemic is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and presents a global health emergency that needs urgent intervention. Viruses constantly change through mutation, and new variants of a virus are expected to occur over time. In the United Kingdom (UK), a new variant called B.

Temporal variation of 212Pb concentration in outdoor air of Milan and a comparison with 214Bi.

Continuous measurement of hourly concentrations of 212Pb attached to aerosol particles was carried out during the whole year 2000 in the outdoor air of Milan (Italy). An improved experimental method based on on-line alpha spectroscopy during atmospheric particulate matter sampling allowed the contemporary determination of 212Pb and 214Bi through the deconvolution of the alpha energy spectral distribution analysis. The 212Pb hourly concentrations were about 100 times lower than 214Bi but showed a similar characteristic diurnal time trend.

Long period study of outdoor radon concentration in Milan and correlation between its temporal variations and dispersion properties of atmosphere.

The results of a survey of outdoor radon concentrations in Milan are reported. Measurements were performed hourly over a continuous four year period from January 1997 to December 2000. Radon concentration was obtained by two means: both direct measurement of radon; and measurement of its decay products.

[The value of ultrasonography in benign breast diseases].

In recent years breast scans have been widely used for the precise diagnosis of breast cancer. However, the value of this diagnostic tool is debatable in comparison to mammography in women of a childbearing age who often present a dense youthful breast. The role of clinical examination as a screening process is also examined.

[Research on the understanding of the relation between patient, gynecologist and breast disease].

The aim of our work was to identify the most important aspects of the relationship between gynecologist and patient who presents himself during our observation because of breast pathology. In order to evaluate all that said above we asked patients to compile a questionnaire characterized by different questions. The results obtained were very satisfactory and at the same time they lead us to a greater engagement towards the prevention of breast neoplasia, especially for those women predisposed to such disease.
