Macroscopical Entangled Coherent State Generator in V configuration atom system
In this paper, we propose a scheme to produce pure and macroscopical
entangled coherent state. When a three-level ''V'' configuration atom interacts
with a doubly reasonant cavity, under the strong classical driven condition,
entangled coherent state can be generated from vacuum fields. An analytical
solution for this system under the presence of cavity losses is also given
Poly[(μ2-azido-κ2 N 1:N 1)[μ2-5-(8-quinolylÂoxyÂmethyl)tetraÂzolato-κ4 N 1,O,N 5:N 4]zinc(II)]
In the title compound, [Zn(C11H8N5O)(N3)]n, the Zn atom is hexaÂcoordinated by five N atoms and one O atom in a distorted octaÂhedral geometry. The chelating 5-(8-quinolyloxymethÂyl)tetraÂzolate ligands are approximately planar, with a dihedral angle of 3.6 (2)° between the quinoline and tetraÂzole planes. Adjacent Zn atoms are linked by two bridging azide ligands across a centre of inversion, and further coordination by one N atom of an adjacent tetraÂzole unit forms two-dimensional frameworks in (100). C—H⋯N interÂactions exist between ligands in neighbouring layers
Twist-teleportation based local discrimination of maximally entangled states
In this work, we study the local distinguishability of maximally entangled
states (MESs). In particular, we are concerned with whether any fixed number of
MESs can be locally distinguishable for sufficiently large dimensions. Fan and
Tian \emph{et al.} have already obtained two satisfactory results for the
generalized Bell states (GBSs) and the qudit lattice states when applied to
prime or prime power dimensions. We construct a general twist-teleportation
scheme for any orthonormal basis with MESs that is inspired by the method used
in [Phys. Rev. A \textbf{70}, 022304 (2004)]. Using this teleportation scheme,
we obtain a sufficient and necessary condition for one-way distinguishable sets
of MESs, which include the GBSs and the qudit lattice states as special cases.
Moreover, we present a generalized version of the results in [Phys. Rev. A
\textbf{92}, 042320 (2015)] for the arbitrary dimensional case.Comment: 7 pages, 2 figure
Physical interaction and functional coupling between ACDP4 and the intracellular ion chaperone COX11, an implication of the role of ACDP4 in essential metal ion transport and homeostasis
Divalent metal ions such as copper, manganese, and cobalt are essential for cell development, differentiation, function and survival. These essential metal ions are delivered into intracellular domains as cofactors for enzymes involved in neuropeptide and neurotransmitter synthesis, superoxide metabolism, and other biological functions in a target specific fashion. Altering the homeostasis of these essential metal ions is known to connect to a number of human diseases including Alzheimer disease, amyotrophic lateral sclerosis, and pain. It remains unclear how these essential metal ions are delivered to intracellular targets in mammalian cells. Here we report that rat spinal cord dorsal horn neurons express ACDP4, a member of Ancient Conserved Domain Protein family. By screening a pretransformed human fetal brain cDNA library in a yeast two-hybrid system, we have identified that ACDP4 specifically interacts with COX11, an intracellular metal ion chaperone. Ectopic expression of ACDP4 in HEK293 cells resulted in enhanced toxicity to metal ions including copper, manganese, and cobalt. The metal ion toxicity became more pronounced when ACDP4 and COX11 were co-expressed ectopically in HEK293 cells, suggesting a functional coupling between them. Our results indicate a role of ACDP4 in metal ion homeostasis and toxicity. This is the first report revealing a functional aspect of this ancient conserved domain protein family. We propose that ACDP is a family of transporter protein or chaperone proteins for delivering essential metal ions in different mammalian tissues. The expression of ACDP4 on spinal cord dorsal horn neurons may have implications in sensory neuron functions under physiological and pathological conditions
Two variants on T2DM susceptible gene HHEX are associated with CRC risk in a Chinese population
Increasing amounts of evidence has demonstrated that T2DM (Type 2 Diabetes Mellitus) patients have increased susceptibility to CRC (colorectal cancer). As HHEX is a recognized susceptibility gene in T2DM, this work was focused on two SNPs in HHEX, rs1111875 and rs7923837, to study their association with CRC. T2DM patients without CRC (T2DM-only, n=300), T2DM with CRC (T2DM/CRC, n=135), cancer-free controls (Control, n=570), and CRC without T2DM (CRC-only, n=642) cases were enrolled. DNA samples were extracted from the peripheral blood leukocytes of the patients and sequenced by direct sequencing. The χ(2) test was used to compare categorical data. We found that in T2DM patients, rs1111875 but not the rs7923837 in HHEX gene was associated with the occurrence of CRC (p= 0.006). for rs1111875, TC/CC patients had an increased risk of CRC (p=0.019, OR=1.592, 95%CI=1.046-2.423). Moreover, our results also indicated that the two variants of HEEX gene could be risk factors for CRC in general population, independent on T2DM (p< 0.001 for rs1111875, p=0.001 for rs7923837). For rs1111875, increased risk of CRC was observed in TC or TC/CC than CC individuals (p<0.001, OR= 1.780, 95%CI= 1.385-2.287; p<0.001, OR= 1.695, 95%CI= 1.335-2.152). For rs7923837, increased CRC risk was observed in AG, GG, and AG/GG than AA individuals (p< 0.001, OR= 1.520, 95%CI= 1.200-1.924; p=0.036, OR= 1.739, 95%CI= 0.989-3.058; p< 0.001, OR= 1.540, 95%CI= 1.225-1.936). This finding highlights the potentially functional alteration with HHEX rs1111875 and rs7923837 polymorphisms may increase CRC susceptibility. Risk effects and the functional impact of these polymorphisms need further validation
Effect of Zaoxiu ointment on wound-healing in experimental second degree burns rats
Purpose: To evaluate the healing efficacy of a Traditional Chinese Medicine (TCM) preparation Zaoxiu Burn Ointment (ZBO) on experimental burns in rats.
Methods: The rats were randomly divided into four groups of eight rats each: control group, silver sulfadiazine (SSD)-treated group, moist exposed burn ointment (MEBO)-treated group and ZBO-treated group. ZBO, SSD and MEBO were applied topically twice daily for 7 days. SSD and MEBO were used as reference control. The observation of wound area contraction and histological analysis of wound tissues were performed. The effect of ZBO on MMPs, VEGF and Type-III collagen proteins of wound tissue in rats were determined by Western blot.
Results: After 10 days of topical treatment with ZBO, ZBO-treated group showed faster reduction in wound area in comparison with control groups (p < 0.01). MMP-2, MMP-9, VEGF and type-III collagen expression of the wound tissue increased significantly (p < 0.05) in comparison with the control burn wounds in rats. The ZBO had no cytotoxic effect on BHK-21 cell line. Histological results showed an overall early recovery and regeneration in ZBO-treated group when compared with control group.
Conclusion: ZBO possesses significant wound-healing activity in full-thickness burn wounds in rats, and can potentially be developed for the treatment of burns patient in future
