La prova del DNA nella pronuncia della Cassazione sul caso Amanda Knox e Raffaele Sollecito

Nell'annullamento della condanna di Amanda Knox e Raffaele Sollecito un ruolo centrale è stato assunto da alcune questioni connesse alla interpretazione delle tracce di DNA. L'articolo si focalizza su alcuni passaggi della sentenza della Corte di Cassazione, con specifico riferimento all'utilizzo e alla valutazione della prova genetica.

Molecular determinants of HPV- induced oropharyngeal squamous cell carcinoma

Head and neck squamous cell carcinoma (HNSCC) arises in the oral cavity,oropharynx,larynx and hypopharynx.Recent works highlighted a subset of HNSCC related to Human Papilloma Virus (HPV) with complete differet molecular progression and associated with a better prognosis than HPV-negative HNSCC. The aim of this work is to culture HPV-positive tumor cells and transfect them with shRNA-expressing plasmids, to prepare RNA from the control and shRNA-treated cells and to measure gene expression....

Presence of Chlamydiales DNA in samples negative by broad-range bacterial 16S rRNA PCRs: new insights into chlamydial pathogenic role.

Since routine eubacterial 16S rRNA PCR does not amplify members of the Chlamydiales order, we tested all samples received in our laboratory during a 10 months period using a pan-Chlamydiales real-time PCR. 3 of 107 samples (2.8%) revealed to be positive, suggesting a role of some Chlamydiales in the pathogenesis of chronic bronchial stenosis or bronchial stenosis superinfection and as agents of orthopaedic prosthesis infections.
