L'effemeride 'bucolica'. Calpurnio Siculo e i giochi dell'intertestualità (Saggio di commento alla V ecloga)

Declamazione e letteratura

2015

This paper is a contribution to the most recent studies about the literature practised at the declamation schools, finding out its fictional aspect. In the first part, we will consider the importance and the risks of such a fictional value. We will go through some paragraphs of Quintilian's Institutio Oratoria (2, 10 and 10, 5); in fact, in this work, the author condemns some excesses, yet he keeps on considering declamation a good practice. In the second part of the paper, a particular case study will be proposed. We will focus on the character of the stepmother, according to the excerpta of Calpurnius Flaccus. We will also analyse four excerpts (4, 12, 22, 35), in which there is always a …

Biopiracy and the right to self-determination of indigenous peoples.

2018

Abstract Background: Since over thirty years, I work on the unclear legal situation of in which indigenous peoples find themselves today in the beginning mainly in the USA and later also in Canada, Australia and New Zealand. The status of indigenous people and native nations is characterized as a mixture of national and international law. Hypothesis/Purpose: To clarify the status of indigenous people it is necessary to analyze and interpret carefully hundreds of old treaties, international declarations and covenants, national statutes and jurisprudence, especially the old leading decisions of the US-Supreme Court. Such an analysis and interpretation should prove that indigenous people have …

Myeloid-Derived Suppressor Cells in Multiple Myeloma: Pre-Clinical Research and Translational Opportunities

2014

Immunosuppressive cells have been reported to play an important role in tumor-progression mainly because of their capability to promote immune-escape, angiogenesis, and metastasis. Among them, myeloid-derived suppressor cells (MDSCs) have been recently identified as immature myeloid cells, induced by tumor-associated inflammation, able to impair both innate and adaptive immunity. While murine MDSCs are usually identified by the expression of CD11b and Gr1, human MDSCs represent a more heterogeneous population characterized by the expression of CD33 and CD11b, low or no HLA-DR, and variable CD14 and CD15. In particular, the last two may alternatively identify monocyte-like or granulocyte-lik…

Translation of genomics-guided RNA-based personalised cancer vaccines: towards the bedside

2014

Cancer is a disease caused by DNA mutations. Cancer therapies targeting defined functional mutations have shown clinical benefit. However, as 95% of the mutations in a tumour are unique to that single patient and only a small number of mutations are shared between patients, the addressed medical need is modest. A rapidly determined patient-specific tumour mutation pattern combined with a flexible mutation-targeting drug platform could generate a mutation-targeting individualised therapy, which would benefit each single patient. Next-generation sequencing enables the rapid identification of somatic mutations in individual tumours (the mutanome). Immunoinformatics enables predictions of mutat…

Erythropoietin restores the anemia-induced reduction in radiosensitivity of experimental human tumors in nude mice

2003

Abstract Purpose The effect of recombinant human erythropoietin (rhEPO) on the radiosensitivity of human tumor xenografts growing in anemic and nonanemic nude mice was studied. Methods and materials Anemia was induced by total body irradiation ([TBI], 2 × 4 Gy) of mice before tumor implantation into the subcutis of the hind leg. The development of anemia was prevented by rhEPO (750 U/kg s.c.) given 3 times weekly starting 2 weeks before TBI. Fourteen days after fractionated TBI (tumor volume of approx. 40 mm 3 ), single-dose irradiation of the tumor with varying doses was performed so that in full dose–response relationship for the probability of tumor cure was obtained. Results Radiation-i…

Artesunate induces oxidative DNA damage, sustained DNA double-strand breaks, and the ATM/ATR damage response in cancer cells.

2011

Abstract Artesunate, the active agent from Artemisia annua L. used in the traditional Chinese medicine, is being applied as a first-line drug for malaria treatment, and trials are ongoing that include this drug in cancer therapy. Despite increasing interest in its therapeutic application, the mode of cell killing provoked by artesunate in human cells is unknown. Here, we show that artesunate is a powerful inducer of oxidative DNA damage, giving rise to formamidopyrimidine DNA glycosylase–sensitive sites and the formation of 8-oxoguanine and 1,N6-ethenoadenine. Oxidative DNA damage was induced in LN-229 human glioblastoma cells dose dependently and was paralleled by cell death executed by ap…

Preclinical and Clinical Characterization of Fibroblast-derived Neuregulin-1 on Trastuzumab and Pertuzumab Activity in HER2-positive Breast Cancer.

2021

[Purpose]: To characterize expression of neuregulin-1 (NRG1), an HER3 ligand, in HER2-positive breast cancer and its relation with the efficacy of trastuzumab with or without pertuzumab.

The Porto European Cancer Research Summit 2021.

2021

Key stakeholders from the cancer research continuum met in May 2021 at the European Cancer Research Summit in Porto to discuss priorities and specific action points required for the successful implementation of the European Cancer Mission and Europe's Beating Cancer Plan (EBCP). Speakers presented a unified view about the need to establish high‐quality, networked infrastructures to decrease cancer incidence, increase the cure rate, improve patient's survival and quality of life, and deal with research and care inequalities across the European Union (EU). These infrastructures, featuring Comprehensive Cancer Centres (CCCs) as key components, will integrate care, prevention and research acros…

Cannabinoid receptor 1 modulates the autophagic flux independent of mTOR- and BECLIN1-complex

2013

Cannabinoid Receptor 1 (CB1) has been initially described as the receptor for Delta-9-Tetrahydrocannabinol in the central nervous system (CNS), mediating retrograde synaptic signaling of the endocannabinoid system. Beside its expression in various CNS regions, CB1 is ubiquituous in peripheral tissues, where it mediates, among other activities, the cell's energy homeostasis. We sought to examine the role of CB1 in the context of the evolutionarily conserved autophagic machinery, a main constituent of the regulation of the intracellular energy status. Manipulating CB1 by siRNA knockdown in mammalian cells caused an elevated autophagic flux, while the expression of autophagy-related genes rema…
