    The land snail taxon Helix straminea Briganti, 1825 has been reintroduced as a valid species in 2014. We provide here a comprehensive account of its taxonomy, distribution, anatomy, phylogeny and karyology in Italy. An overview of the historical views on the validity of the species is presented and faunistic data are reviewed and implemented with new records from Campania and Basilicata. A lectotype is fixed for H. straminea from the syntypes stored in the Muséum d'Histoire Naturelle of Genève, as well as for three other taxa (Helix straminiformis Bourguignat, 1876, Helix yleobia Bourguignat, 1883 and Helix straminea ssp. elongata Bourguignat, 1860). Genital system, radula and karyotype are described for the first time. Molecular analysis of two mitochondrial genes combining GenBank data and the new sequences presented in this paper showed no differentiation between the northern and southern Italian populations. The conservation status of the species and its possible threats are discussed

    Real-world data: come possono aiutare a migliorare la qualità dell’assistenza

    The current COVID pandemic crisis made it even clearer that the solutions to several questions that public health must face require the access to good quality data. Several issues of the value and potential of health data and the current critical issues that hinder access are discussed in this paper. In particular, the paper (i) focuses on “real-world data” definition; (ii) proposes a review of the real-world data availability in our country; (iii) discusses its potential, with particular focus on the possibility of improving knowledge on the quality of care provided by the health system; (iv) emphasizes that the availability of data alone is not sufficient to increase our knowledge, underlining the need that innovative analysis methods (e.g., artificial intelligence techniques) must be framed in the paradigm of clinical research; and (v) addresses some ethical issues related to their use. The proposal is to realize an alliance between organizations interested in promoting research aimed at collecting scientifically solid evidence to support the clinical governance of public healt

    Antineoplastic therapy and urinary enzymes. Preliminary note on the determination of urinary N-acetyl-beta-D-glucosaminidase in patients treated with cisplatin

    We discussed the diagnostic value of urinary enzymes as non invasive test of renal integrity in medicine. Then we assayed the N-Acetyl-beta-D-glucosaminidase (NAG) excretion in urines of inpatients receiving cis-platinum, a useful anti-cancer but nephrotoxic agent fort the proximal tubule; we used the colorimetric instead of fluorimetric procedure, recently described in detail by Price who tested it on patients with a variety of renal diseases. The results demonstrated the sensibility and the specificity of colorimetric procedure, and therefore we concluded that the assay of urinary NAG activity may be used in the clinical chemistry and toxicology laboratory, because the test is simple to perform

    Cadmium distribution within corn plants as a function of cadmium loading of the soil.

    Corn is a widespread crop in some industrialized areas of Northern Italy and Europe where it serves for both animal and human nutrition. In the present paper we examined the distribution of Cd within corn plants grown under both hydroponic and field conditions. The results obtained show that Cd accumulation by different plant tissues may reach saturation without sign of phytoxicity. Thus cadmium pollution can be undetected even when corn plants are grown in the presence of a consistent amount of Cd. Its accumulation within plant tissues is responsible for the entry of the metal into the food chain. Implication for human and animal nutrition are discussed
