Insights into dynamic structural evolution and its sodium storage mechanisms of P2/P3 composite cathode materials for sodium-ion batteries.

Cobalt substitution for manganese sites in NaMnO initiates a dynamic structural evolution process, yielding a composite cathode material comprising intergrown P2 and P3 phases. The novel P2/P3 composite cathode exhibits a reversible phase transition process during Na extraction/insertion, showcasing its attractive battery performance in sodium-ion batteries.

Nickel Nanoparticles Protruding from Molybdenum Carbide Micropillars with Carbon Layer-Protected Biphasic 0D/1D Heterostructures for Efficient Water Splitting.

It remains a tremendous challenge to achieve high-efficiency bifunctional electrocatalysts for both the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER) for hydrogen production by water splitting. Herein, a novel hybrid of 0D nickel nanoparticles dispersed on the one-dimensional (1D) molybdenum carbide micropillars embedded in the carbon layers (Ni/MoC@C) was successfully prepared on nickel foam by a facile pyrolysis strategy. During the synthesis process, the nickel nanoparticles and molybdenum carbide were simultaneously generated under H and CH mixed atmospheres and conformally encapsulated in the carbon layers.

Facilitating Layered Oxide Cathodes Based on Orbital Hybridization for Sodium-Ion Batteries: Marvelous Air Stability, Controllable High Voltage, and Anion Redox Chemistry.

Layered oxides have become the research focus of cathode materials for sodium-ion batteries (SIBs) due to the low cost, simple synthesis process, and high specific capacity. However, the poor air stability, unstable phase structure under high voltage, and slow anionic redox kinetics hinder their commercial application. In recent years, the concept of manipulating orbital hybridization has been proposed to simultaneously regulate the microelectronic structure and modify the surface chemistry environment intrinsically.

Minocycline reduces intracerebral hemorrhage-induced white matter injury in piglets.

Aims: White matter (WM) injury after intracerebral hemorrhage (ICH) results in poor or even fatal outcomes. As an anti-inflammatory drug, minocycline has been considered a promising choice to treat brain injury after ICH. However, whether minocycline can reduce WM injury after ICH is still controversial.

Postoperative executive function in adult moyamoya disease: a preliminary study of its functional anatomy and behavioral correlates.

OBJECTIVE Chronic frontal hemodynamic disturbances are associated with executive dysfunction in adult patients with moyamoya disease (MMD). However, the impact of surgical revascularization on executive dysfunction and its underlying mechanism remains unclear. The aim of the present study was to examine the postoperative radiological correlates of cognitive improvement and thereby explore its underlying mechanism.

[Improving effect of Shengjingsan on spermatogenic function following testicular torsion/detorsion in rats and its mechanism].

Objective: To study the effect of Shengjingsan on spermatogenic function following testicular torsion/detorsion in rats and its action mechanism.

Methods: Forty SD male rats were equally randomized to groups A (sham operation), B (control), C (low-dose Shengjingsan), D (medium-dose Shengjingsan) and E (high-dose Shengjingsan). The model of testicular torsion was established by 720 degrees clockwise torsion of the left testis for 4 hours.

[Association of uPA and uPAR expression with invasive behaviors of urinary transitional cell carcinoma].

Background & Objective: Urokinase-type plasminogen activator (uPA)/its receptor (uPAR), serine protease system, plays a key role in the degradation of extracellular matrix and basement membranes, and intensifying the tumor invasion. The study was designed to investigate the expression of uPA and uPAR in urinary transitional cell carcinoma. The correlation between their expression and tumor invasion was evaluated.

[The expression of urokinase-type plasminogen activator and its receptor in urinary transitional cell carcinoma].

Objective: To probe into the expression and clinical significance of urokinase-type plasminogen activator (uPA) and its receptor (uPAR) in urinary transitional cell carcinoma.

Methods: Expression of uPA and uPAR were detected in 50 cases of renal pelvis and ureter carcinoma and 40 cases of bladder cancer immunohistochemically.

Results: The positive rates of uPA and uPAR were closely correlated to the grade and the stage of urinary transitional cell carcinoma (r = 0.

Conformational Flexibility of Deoxyoligonucleotide d(GGTATACC)(2) in Water.

AT-rich deoxyoligonucleotide provides a binding site possibly at the minor groove for some anti-tumor drugs by hydrophobic or Van der Waals interactions. In this paper, it is demonstrated by study of d (GGTATACC)(2) that the DNA-drug interaction may be dependent on the structural flexibility at the minor groove. The solution structure of d (GGTATACC)(2) in water is described by distance-restrained molecular dynamics calculation and it is suggested that d (GGTATACC)(2) in solution maintains the double helix of B-type with trans conformations of base to sugar and C2'-endo conformation for the deoxyribose ring.
