Confucian Role-Ethics with Non-Domination: Civil Compliance in Times of Crisis.

In this article, combining the Confucian notion of relationality with the republican principle of non-domination, I will shed new light on the ethics of civil compliance in an emergency situation. More specifically, first, by exploring the culturally biased distinctions between individualism and collectivism in the current debates on 'pandemic' nationalism, I will put forward the need for a relationality through which civil cooperation with emergency governance can facilitate the enhancement of both individual freedom and democratic commonality in the long run. Then, by supplementing the moral vision of role-constituted relationality in Confucian role-ethics with the principle of liberty as non-domination in neo-Roman republicanism, I will suggest an ethics of civil compliance which can steer emergency governance toward the consolidation of democratic accountability.

Isoflavones Isolated from the Seeds of Millettia ferruginea Induced Apoptotic Cell Death in Human Ovarian Cancer Cells.

The seeds of Millettia ferruginea are used in fishing, pesticides, and folk medicine in Ethiopia. Here, the anti-cancer effects of isoflavones isolated from M. ferruginea were evaluated in human ovarian cancer cells. We found that isoflavone ferrugone and 6,7-dimethoxy-3',4'-methylenedioxy-8-(3,3-dimethylallyl)isoflavone (DMI) had potent cytotoxic effects on human ovarian cancer cell A2780 and SKOV3. Ferrugone and DMI treatment increased the sub-G1 cell population in a dose-dependent manner in A2780 cells. The cytotoxic activity of ferrugone and DMI was associated with the induction of apoptosis, as shown by an increase in annexin V-positive cells. Z-VAD-fmk, a broad-spectrum caspase inhibitor, and z-DEVD-fmk, a caspase-3 inhibitor, significantly reversed both the ferrugone and DMI-induced apoptosis, suggesting that cell death stimulated by the isoflavones is mediated by caspase-3-dependent apoptosis. Additionally, ferrugone-induced apoptosis was found to be caspase-8-dependent, while DMI-induced apoptosis was caspase-9-dependent. Notably, DMI, but not ferrugone, increased the intracellular levels of reactive oxygen species (ROS), and antioxidant N-acetyl-L-cysteine (NAC) attenuated the pro-apoptotic activity of DMI. These data suggest that DMI induced apoptotic cell death through the intrinsic pathway via ROS production, while ferrugone stimulated the extrinsic pathway in human ovarian cancer cells.
