Transverse Distraction of Great Toe to Enlarge the Donor Site before Finger Reconstruction.

Partial great toe transfer is widely used in finger reconstruction. Although satisfactory results have been reported at the recipient's hand, the donor foot still presents with many problems due to the large amount of tissues harvested. In this study, the Ilizarov technique was utilized to enlarge the great toe in order to minimize the amount of tissue sacrificed of the donor foot.

Quantitative Analysis of Manganese in Underwater Steel Samples Using Long-Short Double-Pulse Laser-Induced Breakdown Spectroscopy.

The long-short double-pulse laser-induced breakdown spectroscopy (LS-DP-LIBS) method was applied to qualitative and quantitative analyses of underwater steel samples to improve the detection ability of underwater measurement. The stable plasma intensity and discrete emission lines were detected using LS-DP-LIBS when comparing the measured results of single-pulse LIBS (SP-LIBS) and LS-DP-LIBS. The long pulse produces a cavitation bubble without plasma, and the short pulse induces the plasma of steel samples within the bubble.

Numerical Study of Concrete Dynamic Splitting Based on 3D Realistic Aggregate Mesoscopic Model.

In mesoscopic scale, concrete is regarded as a heterogeneous three-phase material composed of mortar, aggregate and interfacial transition zone (ITZ). The effect of mesoscopic structure on the mechanical behaviors of concrete should be paid more attention. The fractal characteristics of aggregate were calculated, then the geometric models of aggregate were reconstructed by using fractal Brownian motion.

Interfacial Electron Engineering of Palladium and Molybdenum Carbide for Highly Efficient Oxygen Reduction.

Interfacial electron engineering between noble metal and transition metal carbide is identified as a powerful strategy to improve the intrinsic activity of electrocatalytic oxygen reduction reaction (ORR). However, this short-range effect and the huge structural differences make it a significant challenge to obtain the desired electrocatalyst with atomically thin noble metal layers. Here, we demonstrated the combinatorial strategies to fabricate the heterostructure electrocatalyst of MoC-coupled Pd atomic layers (AL-Pd/MoC) by precise control of metal-organic framework confinement and covalent interaction.

Synthesis of low dimensional hierarchical transition metal oxides a direct deep eutectic solvent calcining method for enhanced oxygen evolution catalysis.

Transition metal oxides (TMOs) are regarded as important materials due to their wide applications in catalysis, sensors, energy storage and conversion devices owing to their advantages of facile synthesis, low cost, and high activity. Here we develop a direct deep eutectic solvent (DES) calcining method to prepare low-dimensional and highly active TMOs for the electrochemical oxygen evolution reaction (OER). Glucose monohydrate and urea can form a glucose-urea DES, which was calcined under a N2 atmosphere to produce 2D N,O-doped graphene.

Melatonin and its metabolite N(1)-acetyl-N(1)-formyl-5-methoxykynuramine improve learning and memory impairment related to Alzheimer's disease in rats.

The aim of this study was to investigate the effect of melatonin (MT) and its metabolite N(1)-acetyl-N(2)-formyl-5-methoxykynuramine (AFMK) on Alzheimer-like learning and memory impairment in rats intracerebroventricularly injected with streptozotocin (STZ).

Increased levels of hyperphosphorylated tau, neurofilament proteins, and malondialdehyde and decreased superoxide dismutase levels were observed in the brains of the rats from the STZ group compared with the brains of the rats from the CON, MT, AFMK high and low group.

Biomimetic design for enhancing the peroxidase mimicking activity of hemin.

Although various nanomaterials have been found to exhibit intrinsic enzyme-like activity, to date, there is no general strategy for designing nanozymes, and their catalytic mechanism has not been studied in depth. To realize the desired enzymatic properties, imitating the structure of natural enzymes is a commendable way to develop effective nanozymes. Inspired by the structure of natural horseradish peroxidase (HRP), we loaded hemin onto amino-modified single-walled carbon nanotubes (SWNT-NH) to prepare an effective peroxidase-like nanozyme (SWNT-NH@hemin).
