Merkel cell polyomavirus oncoproteins induce microRNAs that suppress multiple autophagy genes

Satendra Kumar, Hong Xie, Hao Shi, Jiwei Gao, more

International Journal of Cancer > 146 > 6 > 1652 - 1666

Viruses can inhibit host autophagy through multiple mechanisms, and evasion of autophagy plays an important role in immune suppression and viral oncogenesis. Merkel cell polyomavirus (MCPyV) T‐antigens are expressed and involved in the pathogenesis of a large proportion of Merkel cell carcinoma (MCC). Yet, how MCPyV induces tumorigenesis is not fully understood. Herein, we show that MCPyV T‐antigens...

Journal of Materials Engineering and Performance > 2019 > 28 > 6 > 3600-3613

Dual-phase (DP) steels behave differently under corrosive environment depending upon the volume fractions of phases, mainly martensite, ferrite and bainite. The mechanical behavior and corrosion resistance of DP steels with varying martensite (from 32 to 100%) are investigated. The increase in martensite volume fraction of DP steel results in significant improvement in tensile strength and hardness...

Satendra Kumar, S. Maji, Gopinadhanpillai Gopakumar, M. Joseph, more

Journal of Radioanalytical and Nuclear Chemistry > 2018 > 318 > 3 > 2145-2156

Luminescence of uranyl ion (UO₂²⁺) complexed with picolinate (PA) has been studied in aqueous and acetonitrile medium. In aqueous medium, for UO₂²⁺ to PA ratio of up to 1:20, a 1:1 non-luminescent specie with stability constant of log β = 3.88 was formed. On the contrary, formed specie in acetonitrile medium was luminescent and the enhanced luminescence was due to sensitization by PA and reduction...

Measuring CP nature of top-Higgs couplings at the future Large Hadron electron Collider

Baradhwaj Coleppa, Mukesh Kumar, Satendra Kumar, Bruce Mellado

Physics Letters B > 2017 > 770 > C > 335-341

We investigate the sensitivity of top-Higgs coupling by considering the associated vertex as CP phase (ζt) dependent through the process pe−→t¯hνe in the future Large Hadron electron Collider. In particular the decay modes are taken to be h→bb¯ and t¯ → leptonic mode. Several distinct ζt dependent features are demonstrated by considering observables like cross sections, top-quark polarisation, rapidity...

Iron-based perovskites LaFe_0.5M_0.5O₃, with the orthorhombic (S.G. Pbnm) and rhombohedral (S.G. R-3c) structure for M=Co and Ni, respectively were synthesized using the sol–gel method, in contrast to the literature results. Magnetic investigations reveal that LaFe_0.5Co_0.5O₃ is a canted antiferromagnet and reaches a magnetic transition of 370 K, i.e., much above the 300 K value observed by previous...
