    Evidence of a pluripotent human embryonic stem cell line derived from a cloned blastocyst (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-02-14
    Description: Somatic cell nuclear transfer (SCNT) technology has recently been used to generate animals with a common genetic composition. In this study, we report the derivation of a pluripotent embryonic stem (ES) cell line (SCNT-hES-1) from a cloned human blastocyst. The SCNT-hES-1 cells displayed typical ES cell morphology and cell surface markers and were capable of differentiating into embryoid bodies in vitro and of forming teratomas in vivo containing cell derivatives from all three embryonic germ layers in severe combined immunodeficient mice. After continuous proliferation for more than 70 passages, SCNT-hES-1 cells maintained normal karyotypes and were genetically identical to the somatic nuclear donor cells. Although we cannot completely exclude the possibility that the cells had a parthenogenetic origin, imprinting analyses support a SCNT origin of the derived human ES cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hwang, Woo Suk -- Ryu, Young June -- Park, Jong Hyuk -- Park, Eul Soon -- Lee, Eu Gene -- Koo, Ja Min -- Jeon, Hyun Yong -- Lee, Byeong Chun -- Kang, Sung Keun -- Kim, Sun Jong -- Ahn, Curie -- Hwang, Jung Hye -- Park, Ky Young -- Cibelli, Jose B -- Moon, Shin Yong -- New York, N.Y. -- Science. 2004 Mar 12;303(5664):1669-74.

    Supersonic molecular beam injection effects on tokamak plasma applied non-axisymmetric magnetic perturbation (2016)
    American Institute of Physics (AIP)
    Details
    Publication Date: 2016-08-23
    Description: The change of tokamak plasma behavior by supersonic molecular beam injection (SMBI) was investigated by applying a three-dimensional magnetic perturbation that could suppress edge localized modes (ELMs). From the time trace of decreasing electron temperature and with increasing plasma density keeping the total confined energy constant, the SMBI seems to act as a cold pulse on the plasma. However, the ELM behaviors were changed drastically (i.e., the symptom of ELM suppression has disappeared). The plasma collisionality in the edge-pedestal region could play a role in the change of the ELM behaviors.

    Anti-CotH3 antibodies protect mice from mucormycosis by prevention of invasion and augmenting opsonophagocytosis (2019)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2019
    Description: 〈p〉Mucorales are fungal pathogens that cause mucormycosis, a lethal angioinvasive disease. Previously, we demonstrated that 〈i〉Rhizopus〈/i〉, the most common cause of mucormycosis, invades endothelial cells by binding of its CotH proteins to the host receptor GRP78. Loss of CotH3 renders the fungus noninvasive and attenuates 〈i〉Rhizopus〈/i〉 virulence in mice. Here, we demonstrate that polyclonal antibodies raised against peptides of CotH3 protected diabetic ketoacidotic (DKA) and neutropenic mice from mucormycosis compared to mice treated with control preimmune serum. Passive immunization with anti-CotH3 antibodies enhanced neutrophil inlfux and triggered Fc receptor-mediated enhanced opsonophagocytosis killing of 〈i〉Rhizopus delemar〈/i〉. Monoclonal antibodies raised against the CotH3 peptide also protected immunosuppressed mice from mucormycosis caused by 〈i〉R. delemar〈/i〉 and other Mucorales and acted synergistically with antifungal drugs in protecting DKA mice from 〈i〉R. delemar〈/i〉 infection. These data identify anti-CotH3 antibodies as a promising adjunctive immunotherapeutic option against a deadly disease that often poses a therapeutic challenge.〈/p〉
