The asparagine-linked sugar chains of human erythropoietin produced by recombinant Chinese hamster ovary cells and naturally occurring urinary were liberated hydrazinolysis fractionated paper electrophoresis, lectin affinity chromatography, Bio-Gel P-4 column chromatography. Both erythropoietins had three in one molecule, all which acidic complex type. Structural analysis them revealed that the from both are quite similar except for sialyl linkage. All contain only NeuAc alpha 2----3Gal...
We report the catalytic addition of C–H bonds at C2 position heteroarenes, including pyrroles, indoles, benzofurans, and furans, to unactivated terminal internal alkenes. The reaction is catalyzed by a combination Ni(COD)2 sterically hindered, electron-rich N-heterocyclic carbene ligand or its analogous Ni(NHC)(arene) complex. highly selective for anti-Markovnikov α-olefins, as well formation linear alkylheteroarenes from occurs with substrates containing ketones, esters, amides, boronate...
In a new branch of quantum computing, information is encoded into coherent states, the primary carriers optical communication. To exploit it, bits these states are needed, but it notoriously hard to make superpositions such continuous-variable states. We have realized complete engineering and characterization qubit two Using squeezed vacuum as resource special photon-subtraction technique, we could with high precision prepare an arbitrary superposition single photon. This lead way...
Abstract The stereoregularity of poly(methyl acrylate) and acrylate‐α d ) was determined from the NMR spectra. A method quantitative determination proposed in this paper is based on fact that 100 Mc./sec. spectrum absorption peaks due to methylene protons syndiotactic configurations overlap absorptions only one two isotactic configurations. stereostructure poly(methy1 acrylates) polymerized with anionic catalysts such as Grignard reagents, n ‐butyllithium, LiAlH 4 generally richer diads than...
The histone methyltransferase EZH2, a key epigenetic modifier, is known to be associated with human tumorigenesis. However, the physiological importance of EZH2 and its clinical relevance in endometrial cancer remain unclear. Hence, present study, we investigated expression function cancer. In quantitative real-time PCR analysis 11 cell lines 52 specimens, was significantly overexpressed cells tissues compared that corresponding normal control tissues. Kaplan-Meier survival using data TCGA...
The phase noise of low-noise oscillators is conventionally measured by the cross-spectrum method (CSM), which has a complicated setup. We developed an alternative called zero-crossing analysis with double recorder setup (ZCA-DRS) that much simpler configuration, we previously demonstrated to measure in audible frequency range. In this study, conducted experiments using ZCA-DRS radio A temperature-compensated crystal oscillator was used generate periodic signal at 27 MHz. results obtained...
We propose a new method of spin squeezing atomic spin, based on the interactions between atoms and off-resonant light which are known as paramagnetic Faraday rotation fictitious magnetic field light. Since projection process, squeezed light, or special among not required in this method, it can be widely applied to many systems. The attainable range parameter is zeta greater, similarS(-2/5), where S total limited by additional fluctuations imposed coherent spherical nature distribution.
We develop a simplified light source at 461 nm for laser cooling of Sr without frequency-doubling crystals but with blue diodes. An anti-reflection coated diode in an external cavity (Littrow) configuration provides output power 40 mW nm. Another is used to amplify the up 110 by injection locking. For frequency stabilization, we demonstrate modulation-free polarization spectroscopy hollow cathode lamp. The simplification system achieved this work great importance construction transportable...
Endometrioid endometrial carcinoma, commonly known as type 1 cancer, accounts for >80% of carcinomas and is dependent on estrogen. We recently reported the prognostic significance BIRC5 survivin gene in cancer. Estradiol induces expression estrogen receptor-positive, but not receptor-negative, cancer cells. Kaempferol, a bioflavonoid, reportedly inhibits receptor-α (ERα) hormone receptor-positive breast However, whether kaempferol-mediated inhibition ERα suppresses cell death remains...
We propose a new method to reduce the frequency noise of Local Oscillator (LO) level white phase by maintaining (not destroying projective measurement) coherence ensemble pseudo-spin atoms over many measurement cycles. This scheme uses weak monitor in Ramsey and repeat cycle without initialization we call, "atomic lock (APL)" this paper. APL will achieve as long accumulated during dead time decoherence are smaller than noise. A numerical simulation confirms that with APL, Allan deviation is...
: While the incidence of endometrial cancer continues to rise, therapeutic options remain limited for advanced or recurrent cases, and most cases are resistant therapy. The anti-tumor effect many chemotherapeutic drugs radiotherapy depends on induction DNA damage in cells; thus, activation response (DDR) pathways is considered an important factor affecting resistance When some DDR inactivated, inhibition other can induce cancer-specific synthetic lethality. Therefore, as promising candidates...

Magnetic fine particle-insulator composite films containing Fe-Ni particles and insulating epoxy used for electromagnetic-wave-absorbing were synthesized by a newly developed electrochemical method termed the “layer-by-layer (LbL)-assisted plating method.” A reaction solution water-soluble resin was film fabrication. Cu substrates Ti/Pt plates as cathode anode, respectively. In LbL-assisted plating, attraction of charged to electrostatic force electrodeposition occurred simultaneously. LbL...

κ-casein A was fractionated into 9 subcomponents, all of which were identified as from immunological analyses. The microheterogeneity the subcomponents explained by stepwise increase their carbohydrate contents (0~4mol/mol GalNAc, and 0~8mol/mol NANA). micelle-stabilizing ability increased with contents: rich subcomponent 7 possessed twice stabilizing free 1. sensitivity synthetic casein micelle composed αsl-casein to wheat germ lectin-induced aggregation also NANA contents.
We constructed a cavity QED system with diamagnetic atom of $^{171}\mathrm{Yb}$ and performed projective measurements on single nuclear spin. Since Yb has no electronic spin $1/2$ spin, the procedure polarization state verification can be dramatically simplified compared pseudo-spin-$1/2$ system. By enhancing photon emission rate ${}^{1}{S}_{0}$-${}^{3}{P}_{1}$ transition, measurement is implemented for an time ${T}_{\mathrm{meas}}=30 \mathrm{\ensuremath{\mu}}\mathrm{s}$. Unwanted flip dark...
