Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
The astrochemical observatory: Computational and theoretical focus on molecular chirality changing torsions around O – O and S – S bonds
No full textThe observation of hydrogen peroxide in the interstellar medium represents a remarkable discovery for the astrochemistry community. The prototypical role that this molecule, arguably the simplest chiral molecule, plays in the evolution of life in biospheres, is related to the chirality change transitions associated with the torsional motions around the O - O and the S - S bonds. In this paper, we present an overview on the state-of-art of possible experiments to demonstrate chiral effects discrimination and computational tools applied to peroxides and persulfides

Hemiasterlin derivative (R)(S)(S)-BF65 and Akt inhibitor MK-2206 synergistically inhibit SKOV3 ovarian cancer cell growth
No full textWe reported previously that a hemiasterlin derivative BF65 is a potent anticancer agent that can inhibit microtubule assembly. Here we show that a more potent stereospecific diastereomer (R)(S)(S)-BF65 can synergize with an allosteric Akt inhibitor MK-2206 to suppress the growth of SKOV3 ovarian cancer cells with constitutively active Akt. (R)(S)(S)-BF65 induced mitotic arrest and MK-2206 caused G0/G1 arrest, while the combination of both induced simultaneous G0/G1 and G2/M cell cycle arrest. (R)(S)(S)-BF65 induced phosphorylation and inactivation of Bcl-2, and downregulated Mcl-1, consequently may lead to apoptosis. (R)(S)(S)-BF65 inhibited mitogen-activated protein kinases (MAPKs), which may stimulate cell proliferation upon activation. (R)(S)(S)-BF65 also induced DNA damage after long-term treatment. MK-2206 is known to inhibit phosphorylation and activation of Akt and suppress cancer cell growth. The combination of (R)(S)(S)-BF65 and MK-2206 also inhibited the Akt pathway. Interestingly, MK-2206 upregulated Bcl-2 and induced activation of MAPKs in SKOV3 cells; however, when combined with (R)(S)(S)-BF65, these prosurvival effects were reversed. The combination also more significantly decreased Mcl-1 protein, increased PARP cleavage, and induced gamma-H2AX, a DNA damage marker. Remarkably, MK-2206 enhanced the microtubule depolymerization effect of (R)(S)(S)-BF65. The combination of (R)(S)(S)-BF65 and MK-2206 also markedly inhibited cell migration. Thus, MK-2206 synergizes with (R)(S)(S)-BF65 to inhibit SKOV3 cell growth via downregulating the Akt signaling pathway, and enhancing the microtubule disruption effect of (R)(S)(S)-BF65. (R)(S)(S)-BF65 in turn suppresses Bcl-2 and MAPKs induced by MK-2206. (R)(S)(S)-BF65 and MK-2206 compensate each other leading to increased apoptosis and enhanced cytotoxicity, and may also suppress cancer cell invasion. (C) 2016 Elsevier Inc. All rights reserved
