Effects of Bushenyiqihexue Formula on the Endometrial Gland Apoptosis in Mice with Blastocyst Implantation Dysfunction
ObjectiveTo observe the effects of Bushenyiqihexue Formula (Formula for Tonifying the Kidney, Replenishing qi and Harmonizing Blood, FTKRQHB) on the endometrial gland apoptosis in the mice with blastocyst implantation dysfunction.MethodsThe mice with the first-day pregnancy were divided into the control, model and treatment groups, with 30 in each group, and blastocyst implantation dysfunction was induced by subcutaneous injection of mifepristone in the mice of the model and treatment groups. The pregnancy rate and implantation number of blastocysts were measured and the expressions of proliferating cell nuclear antigen (PCNA), Bax, Bcl-2, and activated caspase-3 were detected in all the three groups.ResultsThe model group had significantly depressed pregnancy rate, implantation number of blastocysts and apoptosis index, and elevated proliferation index of endometrial gland as compared with the control group (P<0.05 or P<0.01). Administration of FTKRQHB (the treatment group) resulted in significant increases in pregnancy rate, implantation number of blastocysts and apoptosis index of the endometrial gland, and a significant decrease in the proliferation index of the endometrial gland as compared with the model group (P<0.05 or P<0.01). The differences in the four indexes between the treatment group and control group were not significant statistically. The Bax and activated caspase-3 expressions in endometrial gland in the model group became significantly lower than that of the control group (P<0.01), whereas those in the treatment group were significant higher than that of the model group (P<0.01). However, the Bax and activated caspase-3 expressions in endometrial gland were similar in both treatment and control groups.ConclusionPromoting the increases in Bax and activated caspase-3 expressions in the endometrial gland and bringing into balance between apoptosis and proliferation of the glandular cells at the implantation window phase by FTKRQHB may contribute to the effects of promoting the establishment of endometrial receptivity and improving blastocyst implantation dysfunction
Anisotropic Pauli spin-blockade effect and spin-orbit interaction field in an InAs nanowire double quantum dot
We report on experimental detection of the spin-orbit interaction field in an
InAs nanowire double quantum dot device. In the spin blockade regime, leakage
current through the double quantum dot is measured and is used to extract the
effects of spin-orbit interaction and hyperfine interaction on spin state
mixing. At finite magnetic fields, the leakage current arising from the
hyperfine interaction is suppressed and the spin-orbit interaction dominates
spin state mixing. We observe dependence of the leakage current on the applied
magnetic field direction and determine the direction of the spin-orbit
interaction field. We show that the spin-orbit field lies in a direction
perpendicular to the nanowire axis but with a pronounced off-substrate-plane
angle. It is for the first time that such an off-substrate-plane spin-orbit
field in an InAs nanowire has been detected. The results are expected to have
an important implication in employing InAs nanowires to construct spin-orbit
qubits and topological quantum devices.Comment: 20 pages, 5 figures, Supporting Informatio
(E)-(2,4-Dichlorophenyl)[2-hydroxy-6-(methoxyimino)cyclohex-1-enyl]methanone
The title compound, C14H13Cl2NO3, was obtained as the product of an attempted synthesis of herbicidally active compounds containing oxime ether and cyclohexenone groups. In the crystal structure, the molecule adopts an endocyclic enol tautomeric form and the cyclohexene ring adopts a distorted envelope form. The oxime ether group has an E configuration, with the methoxy group anti to the ortho-chloro substitutent. Intramolecular O—H⋯O and intermolecular C—H⋯O hydrogen bonds are found in the crystal structure
Dependence of the decoherence of polarization states in phase-damping channels on the frequency spectrum envelope of photons
We consider the decoherence of photons suffering in phase-damping channels.
By exploring the evolutions of single-photon polarization states and two-photon
polarization-entangled states, we find that different frequency spectrum
envelopes of photons induce different decoherence processes. A white frequency
spectrum can lead the decoherence to an ideal Markovian process. Some color
frequency spectrums can induce asymptotical decoherence, while, some other
color frequency spectrums can make coherence vanish periodically with variable
revival amplitudes. These behaviors result from the non-Markovian effects on
the decoherence process, which may give rise to a revival of coherence after
complete decoherence.Comment: 7 pages, 4 figures, new results added, replaced by accepted versio
Space-time dual quantum Zeno effect: Interferometric engineering of open quantum system dynamics
Superposition of trajectories, which modify quantum evolutions by superposing
paths through interferometry, has been utilized to enhance various quantum
communication tasks. However, little is known about its impact from the
viewpoint of open quantum systems. Thus, we examine this subject from the
perspective of system-environment interactions. We show that the superposition
of multiple trajectories can result in quantum state freezing, suggesting a
space-time dual to the quantum Zeno effect. Moreover, non-trivial Dicke-like
super(sub)radiance can be triggered without utilizing multi-atom correlations.Comment: 12 pages and 4 figure
