BioTarget - Ionizing Radiations Effects on Biological Targets

Coordinator:

Simonetta Croci- Professore Associato; Dip. Medicina e Chirurgia, Unità di Neurosc., Univ. di Parma

Participants:

Massimo Manghi - Professore Associato; Dip. Medicina e Chirurgia, Unità di Neurosc., Univ. di Parma

PROJECT GOAL: the investigation on cell cytoskeleton as new biological target of ionizing radiations (IRs). The study models are: Hs 578T (human breast cancer cell line) and Hs 578Bst (human breast epithelial cell line). Herein are compared two diverse IRs, within different relative biological effectiveness (RBE): X-ray and protons. The component of the cytoskeleton looked into is β-actin, which is one of the most common cytoskeleton protein. Followed by cytoskeleton investigations, by means confocal and atomic force microscopy (AFM), the damages are outlined.

MILESTONES 2018 - Experimental The set up for proton and X-ray irradiations of Hs 578Bst cell line was successfully defined thus the beam line time was obtained from the 12^th to 14^th February 2018. The cell membrane denaturation protocol followed by cell fixation procedure were performed as expected. These achievements allowed the AFM measurements of cell topographies. The computational analysis of the AFM images by means hough and curvelet transform are ongoing, showing a higher distribution of shortest fibers in case of 8Gy proton irradiated samples respect to control and to 25 Gy X-ray irradiated samples.

The publication “PS2.M: Looking for a potassium biosensor. L. Bruni et al., Eur. Phys. J.

Plus (2018) 133: 337” leaded to sense K⁺concentrations into the supernatants of the irradiated cells. Pertaining this side of the project the folding protocol of PS2.M, bringing to detect K⁺is ongoing.

MILESTONES 2019 protons and X-ray Irradiation of Hs 578Bst and Hs 578T cell lines. Doses:

16Gy and 8Gy. 16Gy will be fractionated in two doses of 8Gy each. By means Immunocytochemistry staining of β-actin, a specific component of the cytoskeleton will be selected and imaged. The confocal microscopy images of the stained cells will be compared with AFM images of whole cell cytoskeleton.

The definition of a dosimetric parameter based on cell image analysis performed by the wavelet analysis combined with the curvelet transform, will be updated. In order to detect alleged K⁺ outflows due to irradiations, K⁺concentration will be detected into the cell supernatants by PS2.M.

What we would kindly ask to Centro Fermi about 2018 – 2020

The financial support for mission expenses concerning experiments which need of facilities out of the usual laboratories. To be supported on expenditures on attending national and international meetings and conferences and on lab purchasing (e.i. reagents, plastics) for working on the

“biotargets” project.

ACTIVITY

GW data-analysis (parameter estimation) needs to rely on accurate and complete semi-analytical waveform models

• Development and implementation of TEOBResumS, BBHs & BNS, spin-aligned, [Nagar et al., Phys. Rev. D 98, 104052] Tested on GW150914 (BBH) and used on GW170817 (BNS)

• Use of the post-adiabatic approximation to tremendously speed up the waveform generation, [Nagar & Rettegno, arXiv 1805.03891 (in press)]

• Development and testing of phenomenological model for representing the tidal

interactions as obtained from numerical relativity simulations [Dietrich et al.,1804.02235]

• Exploration and development of new factorization and resummation approach to improve the behavior of the post-Newtonian expanded waveform amplitudes in the strong-field, fast velocity regime

[Messina, Maldarella, Nagar, Phys. Rev. D 97, 084016]

• Exploration & testing (versus state-of-the-art numerical simulation) of the tidal sector of TEOBResumsS [Akcay et al, 1812.02744]

• Extension of TEOBResumS so to incorporate nonlinear-in-spin effects (spin-quadratic, spin-cubic, spin quartic) with their dependence on the equation of state [Nagar et al, to appear]

Objectives: Study of the structure of supergravity by means of its symmetries, in particular dualities, with the aim of applying them to concrete physical models, such as graphene and more general Weyl semimetals in condensed matter.

Dualities, like (generalized) electric-magnetic duality and holography, are a crucial feature of supergravity, and they provide a key to the understanding the non- perturbative properties of the theory. Specifically, the gauge/gravity correspondence relates a strongly coupled gauge theory in D dimensions to a classical gravity theory in one dimension higher, allowing a description of a 2+1 dimensional layer of graphene through a supergravity theory in a 3+1 dimensional anti de Sitter space, a simple example of a curved space-time. This top-down approach from higher to lower dimensions is more predictive than the more common bottom-up one, as it is strongly constrained by the properties of the supergravity theory in D=3+1, such as supersymmetry.

We are discussing with the condensed matter groups of the Politecnico di Torino: Prof.

Laviano (experimental) and Prof. Dolcini (theoretical) ³⁴

-Holographic description of graphene starting from a supergravity theory with boundary on AdS4

2018: Reached 100% in[L. Andrianopoli, B.L. Cerchiai, R. D’Auria, M. Trigiante, JHEP 04 (2018) 007]

We have identified the N=2 supergravity solutions with a locally AdS4 geometry and the correct asymptotic behaviour in the Fefferman-Graham parametrization, i.e. the ``ultraspinning" limit of an AdS₄Kerr black hole,so that they reproduce a model (AVZ) describing graphene[Alvarez, Valenzuela, Zanelli, JHEP 1204 (2012) 058]in D=2+1.

- Unconventional Gauge Fixing for Chern-Simons Supergravity [with L. Andrianopoli, P.A. Grassi, M.

Trigiante]

2018: Reached 80%: In a collaboration with UPO, we have explained the relation between the propagating spinor in the AVZ model and the supersymmetry parameter as a particular gauge fixing of CS-SUGRA in the BRST formalism.

2019: We want to analyze the inequivalence of this gauge fixing with the standard one, interpreting it as a twist.

-Topological properties of the D=2+1 theory[with L. Andrianopoli, R. D’Auria, R. Olea, M. Trigiante, J. Zanelli]

2018: Reached 60%: In collaboration with groups in Chile, we have studied the topological properties of the theory in D=2+1, particularly at the boundary of a 1+1 interface (boundary currents), identifying the topological index.

2019: We want to investigate the holographic interpretation in terms of the D=3+1 supergravity theory.

- N>2 Extension of the Unconventional Supersymmetry [with L. Andrianopoli, R. D’Auria, R. Noris, M.

Trigiante]

2019: This should allow the extension to a Non-Abelian gauge group and the study of the spin-orbit interaction.

- New supersymmetric self-dual M2-flux brane solutions of D=11 SUGRA with discrete symmetry group PSL(2,7) [with P. Fré, M.Trigiante]

2019: In a collaboration with UniTo we are constructing new elementary M2-branes with non-constant flux.
