    RIC-HSCT for MF/SS

    No full text
    Advanced-stage mycosis fungoides and Sezary syndrome (MF/SS) have a poor prognosis. Allogeneic hematopoietic stem cell transplantation (HSCT), particularly using a reduced-intensity conditioning (RIC) regimen, is a promising treatment for advanced-stage MF/SS. We performed RIC-HSCT in nine patients with advanced MF/SS. With a median follow-up period of 954days after HSCT, the estimated 3-year overall survival was 85.7% (95% confidence interval, 33.4-97.9%) with no non-relapse mortality. Five patients relapsed after RIC-HSCT; however, in four patients whose relapse was detected only from the skin, persistent complete response was achieved in one patient, and the disease was manageable in other three patients by the tapering of immunosuppressants and donor lymphocyte infusion, suggesting that graft-versus-lymphoma effect and "down-staging" effect from advanced stage to early stage by HSCT improve the prognosis of advanced-stage MF/SS. These results suggest that RIC-HSCT is an effective treatment for advanced MF/SS

    Knowledge Disclosure, Patents and Optimal Organization of Research and Development

    No full text
    We develop a model of two-stage cumulative research and development (R&D), in which one Research Unit (RU) with an innovative idea bargains to license her nonverifiable interim knowledge exclusively to one of two competing Development Units (DUs) via one of two alternative modes: an Open sale after patenting this interim knowledge, or a Closed sale in which precluding further disclosure to a competing DU requires the RU to hold a stake in the licensed DU's post-invention revenues. Both models lead to partial leakage of RU's knowledge from it's description, to the licensed DU alone in a closed sale, and to both DUs in an open sale. We find that higher levels of interim knowledge are more likely to be licensed via closed sales. If the extent of leakage is lower, more RUs choose open sales, generating a non-monotonic relationship between the strength of Intellectual Property Rights (IPR) and aggregate R&D expenditures. We also develop a rationale for the ex ante acquisition of control rights over the RU by a DU, rooted in the RU's incentives to create knowledge under alternative modes of sale thereof, and her wealth constraint in ex interim bargaining.R&D organisation, patents, intellectual property rights

    Impedance studies on PF6- doped Poly(3,4 ethylenedioxythiophene) Devices

    Carrier density, substrate and synthesis temperature dependent impedance measurements have been performed on Poly(3,4-ethylenedioxythiophene) PEDOT] based devices in metal/polymer/metal geometry at room temperature. The relaxation mechanism of carries in these devices can be varied as per the growth condition. It is observed that in stainless steel (SS)/PEDOT/Silver (Ag) devices, as the carrier density decreases the interface related mechanism takes control over bulk transport, but as the synthesis temperature is lowered the bulk transport dominates over interface related mechanism. The substrate dependent studies have shown that the electrode potential can alter the growth of polymer chains, which affects the relaxation mechanism of the carriers
