The Effect of Post Heat Treatment on the Microstructure and Mechanical Properties of Cold-Sprayed Zn-6Cu Deposits.

To explore the feasibility of preparing Zn alloy bulk, Zn-6Cu deposit was prepared by cold-spraying additive manufacturing. Microstructure, tensile and wear behavior were investigated before and after heat treatment. Cold-sprayed Zn-6Cu deposit was constituted by irregular flattening particles and pores after heat treatment.

Network pharmacology analysis and molecular docking using the Chinese herbal agent WYHX formula (according to Yan Dexin): Management of coronary artery disease.

Background: The therapeutic impact of the Wenyang Huoxue (WYXH) formula on coronary atherosclerotic heart disease (CHD) is well established, yet the precise mechanisms are currently not fully understood. This study provides preliminary insights into the potential mechanisms underlying the therapeutic effects of the formula on CHD by utilizing network pharmacology and molecular docking technology.

Materials And Methods: The primary active constituents and their corresponding action targets for the formula were retrieved from the TCMSP database.

Eight Trigrams Boxing Combined with Wenyang Huoxue Recipe Improves Cardiopulmonary Motor Function and the Quality of Life of Patients with Coronary Heart Disease.

Objective: To investigate the therapeutic effects of Eight Trigrams Boxing combined with a Wenyang Huoxue recipe on the cardiopulmonary motor function and quality of life in patients with coronary heart disease after an interventional operation (percutaneous coronary intervention [PCI]); further, to provide new clinical evidence and ideas for integrated traditional Chinese and Western medicine in cardiac rehabilitation.

Methods: Sixty patients were selected and successfully underwent PCI in designated hospitals after four weeks, from June 2018 to September 2020. The patients were randomly divided into a treatment group and control group, and both groups were given standard pharmaceuticals after PCI and the Wenyang Huoxue recipe.

Direct authentication and composition quantitation of red wines based on Tri-step infrared spectroscopy and multivariate data fusion.

A robust data fusion strategy integrating Tri-step infrared spectroscopy (IR) with electronic nose (E-nose) was established for rapid qualitative authentication and quantitative evaluation of red wines using Cabernet Sauvignon as an example. The chemical fingerprints of four types of wines were thoroughly interpreted by Tri-step IR, and the defined spectral fingerprint region of alcohol and sugar was 1200-950 cm. The wine types were authenticated by IR-based principal component analysis (PCA).

Effect of Prescription Tongxin on Endothelial Progenitor Cells in Peripheral Blood.

Context: Coronary heart disease (CHD) refers to a disease where coronary atherosclerosis induces stenosis or obstruction of the blood vessels. Endothelial progenitor cells (EPCs) function to protect and repair the vascular endothelium, and their functional activity state reflects the ability of the body to repair vascular damage. In the peripheral blood of patients with CHD, the density of EPCs decreases, and the function of EPCs is low.

A Comparative Study of Pressureless Sintered Nanostructured Hydroxyapatite/TiO₂ Composites Prepared by Different TiO₂ Addition Methods.

Two methods of TiO₂ addition were applied to prepare hydroxyapatite/TiO₂ (HA/TiO₂) composite, i.e., hydrolysis TiO₂ in HA powders (N-HA/TiO₂) and mixing commercial nano-sized HA and TiO₂ powder (C-HA/TiO₂).

Geographical origin traceability of Cabernet Sauvignon wines based on Infrared fingerprint technology combined with chemometrics.

Mid-infrared (MIR) and near-infrared (NIR) spectroscopy combined with chemometrics were explored to classify Cabernet Sauvignon wines from different countries (Australia, Chile and China). Commercial wines (n = 540) were scanned in transmission mode using MIR and NIR, and their characteristic fingerprint bands were extracted at 1750-1000 cm and 4555-4353 cm. Through the identification system of Tri-step infrared spectroscopy, the correlation between macroscopic chemical fingerprints and geographical regions was explored more deeply.

Effect of Particle Size and Impact Velocity on Collision Behaviors Between Nano-Scale TiN Particles: MD Simulation.

Inter-particle bonding formation which determines qualities of nano-scale ceramic coatings is influenced by particle collision behaviors during high velocity collision processes. In this study, collision behaviors between nano-scale TiN particles with different diameters were illuminated by using Molecular Dynamics simulation through controlling impact velocities. Results show that nano-scale TiN particles exhibit three states depending on particle sizes and impact velocities, i.

Epidermal growth factor receptor-targeted immune magnetic liposomes capture circulating colorectal tumor cells efficiently.

Aim: To compare the capacity of newly developed epidermal growth factor receptor (EGFR)-targeted immune magnetic liposomes (EILs) epithelial cell adhesion molecule (EpCAM) immunomagnetic beads to capture colorectal circulating tumor cells (CTCs).

Methods: EILs were prepared using a two-step method, and the magnetic and surface characteristics were confirmed. The efficiency of capturing colorectal CTCs as well as the specificity were compared between EILs and EpCAM magnetic beads.

[Repression of Nitrogen and Phosphorus Release from Lakeshore Sediment by Five Littoral-zone Plants].

The article researched the effect of L., L., Swartz, and on the nitrogen and phosphorus repression in sandy soil from lower reaches of Yangtze River and clay from stored littoral zone.

[Pollution Characteristics and Evaluation of Nitrogen, Phosphorus and Organic Matter in Sediments of Shanmei Reservoir in Fujian, China].

In order to illuminate pollutants distribution characteristics in sediment of Shanmei Reservoir, sediment samples at 47 sampling stations were collected (include 8 column samples), and concentrations of total nitrogen, total phosphorus and organic matter in the sediment of each station were measured. C/N and the correlation of TN, TP and OM were also analyzed. Finally, pollution assessment for contaminated layer sediments was conducted.

[Response of Inflow Water Quality to Land Use Pattern in Northern Watershed of Lake Erhai].

The inherent relationship between land use pattern and inflow water quality is essential for nonpoint source pollution study. Response of inflow river quality to land use pattern in Northern part of Lake Erhai Watershed was analyzed in aspects of land use composition and configuration using spatial analysis and statistical analysis methods. The results indicated that as land use composition indexes, average slope and vegetation area percentage had significant relationship with TN and TP of inflow rivers.

[Effect of inactivation agents on the phosphorus release from sediment of Lake Dianchi at different temperature].

The influence of temperature on P release from sediment of Lake Dianchi was discussed. Two kinds of inactivation agent schemes (Al2SO4.18H2O and PAC-Polymeric Aluminum Chloride) were used.

Influence of phosphorus on Microcystis growth and the changes of other environmental factors.

The growth processes of Microcystis aeruginosa (FACHB-41) in simulated Taihu Lake water with different phosphorus concentrations were investigated using laboratory microcosms. The algal biomass increased with the increase of phosphorus concentration when it was lower than 0.445 mg/L, while the dissolved oxygen (DO) and pH increased, dissolved inorganic nitrogen(DIN) and light intensity underwater (I) decreased.
