Anisotropic Quasi-particle Decay Dynamics in Antiferromagnetic CuCrPS Single Crystals.

Two-dimensional van der Waals material CuCrPS (CCPS) has attracted significant attention for its coexistence of antiferromagnetic and antiferroelectric states, which have been reported to give rise to strong optical anisotropy. Here, we investigate its anisotropic quasi-particle decay dynamics using polarization-resolved femtosecond transient optical spectroscopy. We observe that the quasi-particle decay dynamics in the CCPS single crystal strongly correlate with its spin ordering.

Relationship between δ-catenin expression and whole-brain small-world network in breast cancer patients before chemotherapy.

Our study aimed to investigate the relationship between δ-catenin expression and whole-brain small-world network in breast cancer patients before chemotherapy using rs-fMRI. The study was based on the hypothesis that different δ-catenin expression levels correspond to distinct brain imaging characteristics. A total of 105 pathologically confirmed breast cancer patients were collected and categorized into high δ-catenin expression (DH, 52 cases) and low expression (DL, 53 cases) groups.

Parabens, triclosan, and triclocarban in aquatic products from Shenzhen, China and the relative health risk.

The consumption of contaminated aquatic products may expose humans to residues of parabens, triclosan (TCS), and triclocarban (TCC). Despite its significance, empirical research on this issue remains limited. In this study, we employed high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) to analyze extracts from 245 aquatic product samples collected randomly from local markets in Shenzhen, Guangdong Province.

Observation of intracranial artery and venous sinus hemodynamics using compressed sensing-accelerated 4D flow MRI: performance at different acceleration factors.

Objective: To investigate the feasibility and performance of 4D flow MRI accelerated by compressed sensing (CS) for the hemodynamic quantification of intracranial artery and venous sinus.

Materials And Methods: Forty healthy volunteers were prospectively recruited, and 20 volunteers underwent 4D flow MRI of cerebral artery, and the remaining volunteers underwent 4D flow MRI of venous sinus. A series of 4D flow MRI was acquired with different acceleration factors (AFs), including sensitivity encoding (SENSE, AF = 4) and CS (AF = CS4, CS6, CS8, and CS10) at a 3.

DTI-ALPS index decreased in patients with Type 2 Diabetes Mellitus.

Backgrounds: Type 2 Diabetes Mellitus (T2DM) has become a significant global public health issue, characterized by a rising prevalence and associated deficits across multiple organ systems. Our study aims to utilize the DTI-ALPS technique to assess the change of ALPS index in T2DM patients, and to explore whether such changes are correlated with cognition level and diffusion parameters.

Methods: The study involved 41 patients with T2DM (mean age, 60.

Fast imaging of lenticulostriate arteries by high-resolution black-blood T1-weighted imaging with variable flip angles and acceleration by compressed sensitivity encoding.

Objective: We investigated the feasibility of using compressed sensitivity encoding (CS-SENSE) to accelerate high-resolution black-blood T1-weighted imaging with variable flip angles (T1WI-VFA) for efficient visualization and characterization of lenticulostriate arteries (LSAs) on a 3.0 T MR scanner.

Materials And Methods: Twenty-five healthy volunteers and 18 patients with the cerebrovascular disease were prospectively enrolled.

Separation of pyrrolidine from tetrahydrofuran by using pillar[6]arene-based nonporous adaptive crystals.

Pyrrolidine, an important feedstock in the chemical industry, is commonly produced vapor-phase catalytic ammoniation of tetrahydrofuran (THF). Obtaining pyrrolidine with high purity and low energy cost has extremely high economic and environmental values. Here we offer a rapid and energy-saving method for adsorptive separation of pyrrolidine and THF by using nonporous adaptive crystals of per-ethyl pillar[6]arene (EtP6).

Pillararene-Induced Intramolecular Through-Space Charge Transfer and Single-Molecule White-Light Emission.

The fabrication of single-molecule white-light emission (SMWLE) materials has become a highly studied topic in recent years and through-space charge transfer (TSCT) is emerging as an important concept in this field. However, the preparation of ideal TSCT-based SMWLE materials is still a big challenge. Herein, we report a bifunctional pillar[5]arene (TPCN-P5-TPA) with a linear donor-spacer-acceptor structure and aggregation-induced emission (AIE) property.

Chemoresponsive Supramolecular Polypseudorotaxanes with Infinite Switching Capability.

Chemoresponsive supramolecular systems with infinite switching capability are important for applications in recycled materials and intelligent devices. To attain this objective, here a chemoresponsive polypseudorotaxane is reported on the basis of a bis(p-phenylene)-34-crown-10 macrocycle (H) and a cyano-substituted viologen guest (G). H and G form a [2]pseudorotaxane (H⊃G) both in solution and in the solid state.

[Surgical treatment of thoracic tuberculosis with one stage posterior debridement and bone grafting fusion and internal fixation].

Objective: To investigate the effect and indication of one stage posterior debridement and bone grafting fusion and internal fixation for thoracic tuberculosis.

Methods: From January 2005 to May 2011,12 patients with thoracic tuberculosis were treated with one stage posterior debridement and pedicle screw fixation combined with regular anti-tuberculosis treatment before and after operation. There were 7 males and 5 females,with an average age of 45 years and average course of 15 months.
