Clinical phenotype of familial amyotrophic lateral sclerosis with gene mutation mimicking proximal myopathy: A case report and literature review.

Amyotrophic lateral sclerosis (ALS) is a disorder with strong clinical and genetic heterogeneity, and its pathogenic mechanism has not been completely clarified. Proximal myopathy is rare in clinical manifestations of ALS. Here, we describe a 34-year-old woman with a 1-year history of symmetrical, proximal limb weakness, and muscle atrophy, with slow progression and no upper motor neuron (UMN) signs.

Experimental test of genuine multipartite nonlocality under the no-signalling principle.

Genuine multipartite nonlocality (GMN) has been recognized as the strongest form of multipartite quantum correlation. However, there exist states that cannot violate the Svetlichny inequality derived from the standard definition of GMN, even though they possess GMN properties. The reason is that the standard definition of GMN allows correlations that permit signalling among parties, which is inconsistent with an operational definition.

Generation and applications of an ultrahigh-fidelity four-photon Greenberger-Horne-Zeilinger state.

High-quality entangled photon pairs generated via spontaneous parametric down-conversion have made great contributions to the modern quantum information science and the fundamental tests of quantum mechanics. However, the quality of the entangled states decreases sharply when moving from biphoton to multiphoton experiments, mainly due to the lack of interactions between photons. Here, for the first time, we generate a four-photon Greenberger-Horne-Zeilinger state with a fidelity of 98%, which is even comparable to the best fidelity of biphoton entangled states.

Dynamics of quantum correlation between separated nitrogen-vacancy centers embedded in plasmonic waveguide.

We investigate the dynamics of quantum correlation between two separated nitrogen vacancy centers (NVCs) placed near a one-dimensional plasmonic waveguide. As a common medium of the radiation field of NVCs propagating, the plasmonic waveguide can dynamically induce quantum correlation between the two NVCs. It is interesting to find that such dynamically induced quantum correlation can be preserved in the long-time steady state by locally applying individual driving on the two NVCs.

Ursolic acid derivative ameliorates streptozotocin-induced diabestic bone deleterious effects in mice.

Objective: This study was performed to investigate bone deteriorations of diabetic mice in response to the treatment of ursolic acid derivative (UAD).

Methods: The biomarkers in serum and urine were measured, tibias were taken for the measurement on gene and protein expression and histomorphology analysis, and femurs were taken for the measurement on bone Ca and three-dimensional architecture of trabecular bone.

Results: UAD showed a greater increase in bone Ca, BMD and significantly increased FGF-23 and OCN, reduced PTH and CTX in diabetic mice.

Experimental investigation of classical and quantum correlations under decoherence.

It is well known that many operations in quantum information processing depend largely on a special kind of quantum correlation, that is, entanglement. However, there are also quantum tasks that display the quantum advantage without entanglement. Distinguishing classical and quantum correlations in quantum systems is therefore of both fundamental and practical importance.

On-capillary chemiluminescence detection for capillary electrophoresis with a single capillary.

On-capillary chemiluminescence detection for capillary electrophoresis with a single capillary was reported. A hole (about 30 microm diameter) was made on the capillary wall at about 50.5 cm from the inlet end.

In-capillary solid-phase extraction-capillary electrophoresis for the determination of chlorophenols in water.

A novel CE method combined with SPE in a single capillary was developed for analysis of chlorophenols in water. A frit of 0.5 mm was first made by a sol-gel method, followed by packing a SPE sorbent in the inlet end of the capillary.

Isoelectric focusing sample injection for capillary zone electrophoresis in a fused silica capillary.

An improvement has been made to couple isoelectric focusing (IEF) sample injection and capillary zone electrophoresis in an untreated fused silica capillary. Electroosmotic flow is efficiently prevented by simply using a rubber block at the outlet end of the capillary during IEF sample injection. The experimental conditions that affect the concentration effect are discussed.
