Introduction: Parkinson disease (PD) is the second most common neurodegenerative disease affecting older individuals with signs of motor disability and cognitive impairment. Epicatechin (EC) and edaravone have neuroprotective effects most probably due to their antioxidant activity; however, a limited number of studies have considered their role in PD. This research aimed at investigating the ne...

The e-bidding platform of electric enterprise group purchase business is regard as a complex system of interrelated economic, organizational, social and elements as well as the external and internal information flows of a company. Getting positive synergistic effect is one of the important factors for the enterprise group procurement business innovation. The paper showcase the synergistic effec...

In this work, a series of hollow carbon nanospheres simultaneously doped with N and Fe-containing species are prepared by Fe(3+)-mediated polymerization of dopamine on SiO2 nanospheres, carbonization and subsequent KOH etching of the SiO2 template. The electrochemical properties of the hollow nanospheres as nonprecious-metal electrocatalysts for oxygen reduction reaction (ORR) are characterized...

background: radon and its short-lived decay products are considered as the important sources of public exposure to natural radioactivity. the synergistic interaction between tobacco smoking and radon is known to be an actual problem. this study has provided a mathematical description and prognosis of the carcinogenic effects after combined action of radon with smoking. materials and methods: a ...

The synergistic effect of 18-crown-6 derivatives, such as 18-crown-6 (18C6), cis-dicyclohexano-18-crown-6 (DC18C6) and dibenzo-18-crown-6 (DB18C6), on the extraction of trivalent lanthanoids (Ln(3+)) into an ionic liquid, 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide, with 2-thenoyltrifluoroacetone (Htta) was investigated. The extractability of lighter Ln(3+) was enhanced by ad...

Bioenergy production from hydrochar via catalytic thermal conversion is of increasing importance to easing the energy shortage. The pyrolysis characteristics derived sawdust (HSD) with calcined eggshell (CES) were investigated by thermogravimetric–Fourier transform infrared spectroscopy–mass spectrometry (TG-FTIR-MS) method. Kinetic and thermodynamic parameters determined two iso-conversional m...

the paper showcase the synergistic effect framework and apply it to a study on electricity energy groups of internet bidding platform on B2B supply business. We enumerate electricity grid enterprise group’s purchase system. Since 2006, by setting up the multi-layer purchase system based on internet. Chinese energy enterprise group began to adopt internet supply platform and take full advantage ...

In this study, hydrothermal synthesis was used to prepare α-Ni(OH) 2 , which is a steady-state photocatalytic material. Furthermore, ball milling for the 1:1 loading of with nano-alumina (Al O 3 ), hexagonal boron nitride (h-BN), and activated carbon (AC). The performances these four materials in degradation fracturing flowback fluid were investigated under synergistic catalytic effect ozone. r...
