Three-Dimensional Nickel Foam-Based Lithiophilic LPP-NiS@Ni Current Collector for Dendrite-Free Lithium Anode.

Lithium metal has been treated as one of the most promising anode materials for next-generation rechargeable batteries due to its extremely high theoretical capacity. However, its practical application is hindered by inhomogeneous lithium deposition and uncontrolled dendrite growth. In this work, we prepared a three-dimensional nickel foam (NF)-based current collector with a lithiophilic interface layer through facile hydrothermal and coating methods.

Study on multi-target effects of the novel HDAC6 inhibitor W5 on Aβ/Cu-induced Alzheimer's disease model of rats.

Histone deacetylase 6 (HDAC6) is a key therapeutic target in neurodegenerative diseases such as Alzheimer's disease (AD), which has been demonstrated to play an essential role in memory function and microtubule-associated tau physiology. In this study, W5 was used to treat AD model rats induced by Aβ/Cu to study the improving effect of W5 on learning and memory impairment in AD rats and its related mechanism, to provide the basis for the subsequent development of W5 as an anti-AD drug. Results showed that W5 could decrease the expression of Aβ, Tau, and p-Tau proteins in the hippocampus of AD rats to inhibit the formation of senile plaques and neurofibrillary tangles, down-regulate the expression of Bax mRNA and Caspase-3 mRNA, and up-regulate the expression of Bcl-2 mRNA to reduce the apoptosis of neuron cells, reverse the expression of TNF-α, IL-1β and IL-6 mRNA to regulate neuroinflammatory response in AD rat brain.

Protective effects of myricetin and morin on neurological damage in Aβ/Al -induced Alzheimer's disease model of rats.

Alzheimer's disease (AD) is a degenerative neurological disorder with unclear pathogenesis. Single-target drugs have very limited efficacy in treating AD, but synthetic multi-target drugs have poor efficacy and safety. Therefore, finding suitable natural multi-target drugs against AD is of great interest for research studies.

Determination and analysis of patulin in apples, hawthorns, and their products by high-performance liquid chromatography.

This study aimed to establish a high-performance liquid chromatography (HPLC) method to investigate the residues of patulin in apples, hawthorns, and their products. A total of 400 samples were collected from online shopping plats and supermarkets in China, including apples (n = 50), hawthorns (n = 50), and their products (apple juice, apple puree, apple jam, hawthorn juice, hawthorn chips, and hawthorn rolls, n = 300). In this experiment, this method had good linearity and a recovery of 82.

A quantitative analysis method for a new glycogen synthase kinase-3 inhibitor and its pharmacokinetics in rats.

Alzheimer's disease (AD), as a chronic and frequent neurodegenerative disease in the elderly population, has caused a huge economic burden to society, family, and other aspects. (E)-N-(4-(((2-amino-5-phenylpyridin-3-yl) imino) methyl) pyridine-2-yl) cyclopropanecarboxamide (PIMPC), a new glycogen synthase kinase-3 (GSK-3) inhibitor, has been designed and synthesized as a potential anti-AD compound with antioxidant and metal chelating properties. In this study, we established an HPLC method for the determination of PIMPC, which has high accuracy, good sensitivity, and repeatability.

Study on multi-target effects of PIMPC on Aβ/Cu-induced Alzheimer's disease model of rats.

Glycogen synthase kinase-3 (GSK-3), a key role in the pathogenesis of Alzheimer's disease (AD), has been linked with the formation of β-amyloid (Aβ), tubulin-associated unit (tau) protein phosphorylation and apoptosis. Moreover, the excessive presence of elements such as copper (Cu) can promote Aβ aggregation and increase the risk of AD. Combined with the role of GSK-3 and metal elements in AD, a metal-chelating imine GSK-3 inhibitor N-(4-{[(2-amino-5-phenylpyridin-3-ylidene)imino]methyl}pyridin-2-yl)cyclopropanecarboxamide (PIMPC) was designed and synthesized.

Deep Multi-Layer Perception Based Terrain Classification for Planetary Exploration Rovers.

Accurate classification and identification of the detected terrain is the basis for the long-distance patrol mission of the planetary rover. But terrain measurement based on vision and radar is subject to conditions such as light changes and dust storms. In this paper, under the premise of not increasing the sensor load of the existing rover, a terrain classification and recognition method based on vibration is proposed.

Hollow Carbon Nanopolyhedra for Enhanced Electrocatalysis via Confined Hierarchical Porosity.

A novel strategy for the fabrication of hollow Co and N-codoped carbon nanopolyhedra (H-CoNC) from metal-organic framework (MOF) using in situ evaporation of ZnO nanosphere templates is proposed. The excess Zn supply during the pyrolysis process is found beneficial in terms of high nitrogen (≈9.75 at%), relatively homogenous CoN bonding, and the electrochemically accessible hierarchical porous system.
