Pharmacological activation of FOXO3 suppresses triple-negative breast cancer in vitro and in vivo
Triple-negative breast cancer (TNBC) is the most lethal form of breast cancer. Lacking effective therapeutic options hinders treatment of TNBC. Here, we show that bepridil (BPD) and trifluoperazine (TFP), which are FDA-approved drugs for treatment of schizophrenia and angina respectively, inhibit Akt-pS473 phosphorylation and promote FOXO3 nuclear localization and activation in TNBC cells. BPD and TFP inhibit survival and proliferation in TNBC cells and suppress the growth of TNBC tumors, whereas silencing FOXO3 reduces the BPD- and TFP-mediated suppression of survival in TNBC cells. While BPD and TFP decrease the expression of oncogenic c-Myc, KLF5, and dopamine receptor DRD2 in TNBC cells, silencing FOXO3 diminishes BPD- and TFP-mediated repression of the expression of these proteins in TNBC cells. Since c-Myc, KLF5, and DRD2 have been suggested to increase cancer stem cell-like populations in various tumors, reducing these proteins in response to BPD and TFP suggests a novel FOXO3-dependent mechanism underlying BPD- and TFP-induced apoptosis in TNBC cells
Language of Lullabies: The Russification and De-Russification of the Baltic States

Frequency Tuned Planar Inverted F Antenna with L Shaped Slit Design for Wide Frequency Range.
yesA frequency tuned antenna has been designed to meet the coverage requirements of the DCS, PCS, UMTS and WLAN bands. The antenna consists of a main patch, and a planar inverted L (PIL) slot. The radiator patch is fed, and shorted, using simple feed lines with broadband characteristics. The handset represents the finite ground plane, and a varactor diode is mounted across the middle of the slot for tuning purposes. Initial tuning was obtained by placing lumped capacitors, instead of the varactor, over the radiator. Good agreement is obtained between the predicted and measured input return loss, gain and radiation pattern over the tuned frequency range.MSCR
What Consensus? Ideology, Politics and Elections Still Matter
This article, which was prepared for an ABA Antitrust Section Panel, discusses the role of ideology and politics in antitrust enforcement and the impact of elections in the last twenty year on enforcement and policy at the federal antitrust agencies. The article explains the differences in antitrust ideologies and their impact on policy preferences. The article then uses a database of civil non-merger complaints by the DOJ and FTC over the last three Presidential administrations to analyze changes in the number, type and other characteristics of antitrust enforcement. It also discusses change in vertical merger enforcement and other antirust policies such as amicus briefs, reports and guidelines. The article concludes that elections do matter and that the impact of elections on the DOJ and FTC has differed significantly
