ROLE OF EJECTA CLUMPING AND BACK-REACTION OF ACCELERATED COSMIC RAYS IN THE EVOLUTION OF TYPE Ia SUPERNOVA REMNANTS

2012

We investigate the role played by initial clumping of ejecta and by efficient acceleration of cosmic rays (CRs) in determining the density structure of the post-shock region of a Type Ia supernova remnant (SNR) through detailed 3D MHD modeling. Our model describes the expansion of a SNR through a magnetized interstellar medium (ISM), including the initial clumping of ejecta and the effects on shock dynamics due to back-reaction of accelerated CRs. The model predictions are compared to the observations of SN 1006. We found that the back-reaction of accelerated CRs alone cannot reproduce the observed separation between the forward shock (FS) and the contact discontinuity (CD) unless the energ…

Apoptosis and cell growth arrest in A375 human melanoma cells by diorganotin(IV) and triorganotin(IV) complexes of [meso-Tetra(4-sulfonatophenyl)porp…

2011

In previous studies we have demonstrated that two derivatives of meso-Tetra(4-sulfonatophenyl)porphine (TPPS), (Bu2Sn)2TPPS and (Bu3Sn)4TPPS, cause apoptotic death of A375 melanoma cells and, at lower concentrations, arrest of cell proliferation. In the present study, we examined if the manganese metal inside the porphyrin cavity could improve the efficacy of this class of compounds. Thus, [meso- Tetra(4-sulfonatophenyl)porphine]Mn(III)Cl (=MnTPPS) derivatives, namely (Me2Sn)2MnTPPS, (Bu2Sn)2MnTPPS, (Me3Sn)4MnTPPS and (Bu3Sn)4MnTPPS, were tested on the A375 human melanoma cell line. A cytotoxicity assay showed that (Bu2Sn)2MnTPPS and (Bu3Sn)4MnTPPS were highly cytotoxic by inducing apoptosi…
