    Description: EWS (Ewing sarcoma) encodes an RNA/ssDNA binding protein that is frequently rearranged in a number of different cancers by chromosomal translocations. Physiologically, EWS has diverse and essential roles in various organ development and cellular processes. In this study, we uncovered a new role of EWS in mitochondrial homeostasis and energy...

    Description: Heat-shock protein of 90 kDa (Hsp90) is an essential molecular chaperone that adopts different 3D structures associated with distinct nucleotide states: a wide-open, V-shaped dimer in the apo state and a twisted, N-terminally closed dimer with ATP. Although the N domain is known to mediate ATP binding, how Hsp90 senses...

    Description: The non-canonical NF-kappaB pathway forms a major arm of NF-kappaB signalling that mediates important biological functions, including lymphoid organogenesis, B-lymphocyte function, and cell growth and survival. Activation of the non-canonical NF-kappaB pathway involves degradation of an inhibitory protein, TNF receptor-associated factor 3 (TRAF3), but how this signalling event is controlled is still unknown. Here we have identified the deubiquitinase OTUD7B as a pivotal regulator of the non-canonical NF-kappaB pathway. OTUD7B deficiency in mice has no appreciable effect on canonical NF-kappaB activation but causes hyperactivation of non-canonical NF-kappaB. In response to non-canonical NF-kappaB stimuli, OTUD7B binds and deubiquitinates TRAF3, thereby inhibiting TRAF3 proteolysis and preventing aberrant non-canonical NF-kappaB activation. Consequently, the OTUD7B deficiency results in B-cell hyper-responsiveness to antigens, lymphoid follicular hyperplasia in the intestinal mucosa, and elevated host-defence ability against an intestinal bacterial pathogen, Citrobacter rodentium. These findings establish OTUD7B as a crucial regulator of signal-induced non-canonical NF-kappaB activation and indicate a mechanism of immune regulation that involves OTUD7B-mediated deubiquitination and stabilization of TRAF3.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3578967/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3578967/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hu, Hongbo -- Brittain, George C -- Chang, Jae-Hoon -- Puebla-Osorio, Nahum -- Jin, Jin -- Zal, Anna -- Xiao, Yichuan -- Cheng, Xuhong -- Chang, Mikyoung -- Fu, Yang-Xin -- Zal, Tomasz -- Zhu, Chengming -- Sun, Shao-Cong -- AI057555/AI/NIAID NIH HHS/ -- AI064639/AI/NIAID NIH HHS/ -- CA137059/CA/NCI NIH HHS/ -- GM84459/GM/NIGMS NIH HHS/ -- P30 CA016672/CA/NCI NIH HHS/ -- R01 CA137059/CA/NCI NIH HHS/ -- R01 GM084459/GM/NIGMS NIH HHS/ -- T32 CA009598/CA/NCI NIH HHS/ -- T32CA009598/CA/NCI NIH HHS/ -- England -- Nature. 2013 Feb 21;494(7437):371-4. doi: 10.1038/nature11831.

    Description: Transient expression of the Pseudomonas syringae avirulence gene avrPto in plant cells resulted in a Pto-dependent necrosis. The AvrPto avirulence protein was observed to interact directly with the Pto resistance protein in the yeast two-hybrid system. Mutations in the Pto and avrPto genes which reduce in vivo activity had parallel effects on association in the two-hybrid assay. These data suggest that during infection the pathogen delivers AvrPto into the plant host cell and that resistance is specified by direct interaction of Pto with AvrPto.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Scofield -- Tobias -- Rathjen -- Chang -- Lavelle -- Michelmore -- Staskawicz -- New York, N.Y. -- Science. 1996 Dec 20;274(5295):2063-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉S.

    Description: Sustainable community development encompasses three aspects: “Lifestyle”, “Production” and “Ecology”. Among them, “Lifestyle” is closest to people and reflects basic human needs. Creating outdoor spaces that encourage residents to engage in leisure activities will not only provide them with spiritual sustenance but also fulfil one of the key criteria in sustainable community development. This study explores the relationship between design elements of outdoor leisure spaces and types of leisure activities from residents' perspective with the goal to inform future spatial planning. The study collected 365 valid questionnaires from Tainan residents. Factor analysis was used to extract factors from design elements of outdoor leisure spaces, and regression analysis was applied to understand the effect level. The result shows design elements have positive effect on the types of leisure activities. In addition, different elements exert different influences on the choice of activities.

    Notes: ZnSe epitaxial layers were successfully grown on (111) Si substrates by low-pressure metalorganic chemical vapor deposition. It is not necessary that the reactant inlet tubes project to near the substrates. From x-ray and scanning electron microscopy examinations, single-crystalline ZnSe epilayers with mirrorlike surfaces can be obtained. The carrier concentration profile shows that the carrier distribution in the epilayer is very uniform. The electron mobility of the epilayer at room temperature is 280 cm2 /V s. The efficient 77-K photoluminescence indicates that the ZnSe epilayers are of good quality.

    Notes: The optical properties and band alignment of ZnSe/ZnMgBeSe heterostructures are investigated. Two sets of ZnSe/ZnMgBeSe multi-quantum-well structures that consist of five or three wells with different well thicknesses and 100-nm-thick ZnMgBeSe barrier layers are grown on GaAs (100) substrates by molecular beam epitaxy. Low-temperature photoluminescence spectra show dominant sharp excitonic emission whose peak position systematically shifts to the higher energy side with decreasing the well thickness. Photoluminescence excitation spectra show optical transitions between excited quantum levels in addition to the ground levels. The standard analysis based on the effective-mass approximation gives the valence band offset of ΔEυ=(0.4±0.1)ΔEg. This is consistent with calculated values based on Harrison's linear combination of atomic orbitals theory. © 2002 American Institute of Physics.

    Notes: This paper briefly surveys the three compact, high-current accelerators that are presently under development in the United States in support of a national program. In addition, it reports recent experimental results from the Naval Research Laboratory (NRL) modified betatron [Phys. Rev. Lett. 64, 2374 (1990)] with emphasis on the electron-cyclotron resonance that presently limits the energy of the beam to approximately 18 MeV. Finally, it briefly addresses selective existing and prospective applications of accelerators.
