Rad51 and BRCA2 - New Molecular Targets for Sensitizing Glioma Cells to Alkylating Anticancer Drugs
2011
First line chemotherapeutics for brain tumors (malignant gliomas) are alkylating agents such as temozolomide and nimustine. Despite growing knowledge of how these agents work, patients suffering from this malignancy still face a dismal prognosis. Alkylating agents target DNA, forming the killing lesion O(6)-alkylguanine, which is converted into DNA double-strand breaks (DSBs) that trigger apoptosis. Here we assessed whether inhibiting repair of DSBs by homologous recombination (HR) or non-homologous end joining (NHEJ) is a reasonable strategy for sensitizing glioma cells to alkylating agents. For down-regulation of HR in glioma cells, we used an interference RNA (iRNA) approach targeting Ra…
Changes in gene expression linked with adult reproductive diapause in a northern malt fly species: a candidate gene microarray study
2010
Abstract Background Insect diapause is an important biological process which involves many life-history parameters important for survival and reproductive fitness at both individual and population level. Drosophila montana, a species of D. virilis group, has a profound photoperiodic reproductive diapause that enables the adult flies to survive through the harsh winter conditions of high latitudes and altitudes. We created a custom-made microarray for D. montana with 101 genes known to affect traits important in diapause, photoperiodism, reproductive behaviour, circadian clock and stress tolerance in model Drosophila species. This array gave us a chance to filter out genes showing expression…
Disabilità e dolore: il caso della cannabis terapeutica. Fisionomia e limiti del diritto alla cura nel decreto del Ministero della Salute 9 novembre …
2022
Il contributo illustra l’originale struttura del mercato della cannabis terapeutica, ricostruendo la legislazione italiana in materia, di cui si mette in luce la dubbia compatibilità con i principi di libera circolazione e di concorrenza. La specialità del settore è comunemente giustificata alla luce delle esigenze di salute pubblica, dell’ordine pubblico e della pubblica sicurezza la cui tutela è sottesa anche ai più recenti interventi normativi: specialità che non consente tuttavia di giudicare la regolazione della cannabis terapeutica conforme all’interpretazione consolidata degli articoli 49, 52, 56, 106 T.f.Ue e alla altrettanto stabile giurisprudenza della Corte costituzionale italia…

Spatio-temporal variation of throughfall in a hyrcanian plain forest stand in Northern Iran
2018
Abstract Elucidating segregation of precipitation in different components in forest stands is important for proper forest ecosystems management. However, there is a lack of information on important rainfall components viz. throughfall, interception and stemflow in forest watersheds particularly in developing countries. We therefore investigated the spatiotemporal variation of important component of throughfall for a forest stand in a Hyrcanian plain forest in Noor City, northern Iran. The study area contained five species of Quercus castaneifolia, Carpinus betulus, Populus caspica and Parrotia persica. The research was conducted from July 2013 to July 2014 using a systematic sampling method…

La debolezza dei legami forti
2011
Ci sono forme di capitale sociale che promuovono lo sviluppo e altre che lo inibiscono. Durante il Medioevo, maghrebini e genovesi si contendevano il primato commerciale nell'area del Mediterraneo. A soccombere furono i maghrebini che godevano di una dotazione di capitale sociale comunitario, e cioè di affidabilità interna, maggiore dei genovesi. Proprio per questo non sentirono l'esigenza di sviluppare sistemi per rendere sicure le transazioni commerciali fra estranei.
Phylostratic Shift of Whole-Genome Duplications in Normal Mammalian Tissues towards Unicellularity Is Driven by Developmental Bivalent Genes and Reve…
2020
Tumours were recently revealed to undergo a phylostratic and phenotypic shift to unicellularity. As well, aggressive tumours are characterized by an increased proportion of polyploid cells. In order to investigate a possible shared causation of these two features, we performed a comparative phylostratigraphic analysis of ploidy-related genes, obtained from transcriptomic data for polyploid and diploid human and mouse tissues using pairwise cross-species transcriptome comparison and principal component analysis. Our results indicate that polyploidy shifts the evolutionary age balance of the expressed genes from the late metazoan phylostrata towards the upregulation of unicellular and early m…

An integrated approach based on uniform quantization for the evaluation of complexity of short-term heart period variability: Application to 24 h Hol…
2007
We propose an integrated approach based on uniform quantization over a small number of levels for the evaluation and characterization of complexity of a process. This approach integrates information-domain analysis based on entropy rate, local nonlinear prediction, and pattern classification based on symbolic analysis. Normalized and non-normalized indexes quantifying complexity over short data sequences (â¼300 samples) are derived. This approach provides a rule for deciding the optimal length of the patterns that may be worth considering and some suggestions about possible strategies to group patterns into a smaller number of families. The approach is applied to 24 h Holter recordings of …
