An efficient unsupported nanoporous nickel (NiNPore) material for the hydrogenation of carbonates to formic acid (FA) in water was investigated for the first time.
A novel approach for the production of 2,5-hexanedione (HDN) and 3-methyl-2-cyclopenten-1-one (3-MCO) from 5-hydroxymethylfurfural (HMF) by water splitting with Zn is reported for the first time.
The flexible and rechargeable energy storage device with excellent performance is highly desired due to the demands of portable and wearable devices. Herein, by integrating the bendability and stretchability of Polyvinyl alcohol (PVA), pseudocapacitance of Polyaniline (PANI), and the charge transport ability of carbon nanotubes (CNTs), PVA/CNT/PANI flexible film was fabricated as supercapacitor electrodes with excellent electrochemical performance and flexibility. Full-solid supercapacitor is prepared based on PVA/H

gel electrolyte and as-prepared film electrodes. The device achieves an areal capacitance of 196.5 mF cm

with high cycling stability. The flexible properties of PVA, the conductivity of CNT, and the pseudo-capacitance of PANI contribute to the superior performance. Present work develops a facile and effective way for preparing flexible electrode materials.
Graphical Abstract

Amyloid
aggregation is a ubiquitous form of protein misfolding
underlying the pathologies of Alzheimer’s disease (AD), Parkinson’s
disease (PD), and type 2 diabetes (T2D), three primary forms of human
amyloid diseases. While much has been learned about the origin, diagnosis,
and management of these neurological and metabolic disorders, no cure
is currently available due in part to the dynamic and heterogeneous
nature of the toxic oligomers induced by amyloid aggregation. Here,
we synthesized β-casein-coated iron oxide nanoparticles (βCas
IONPs) via a 2-(bis-((phosphonic acid)methyl)amino)ethyl-(poly(oligo
ethylene glycol)methyl ether acrylate)-b-(poly(N-ethyl-2,3-dibromomaleimide)acrylate)-((butylthio)-carbonothioyl)thio
propionate (BPA-P(OEGA-b-DBM)) block copolymer linker.
Using a thioflavin T kinetic assay, transmission electron microscopy,
Fourier transform infrared spectroscopy, discrete molecular dynamics
simulations, and cell viability assays, we examined the Janus characteristics
and the inhibition potential of βCas IONPs against the aggregation
of amyloid β (Aβ), α synuclein (αS), and human
islet amyloid polypeptide (IAPP), which are implicated in the pathologies
of AD, PD, and T2D. Incubation of zebrafish embryos with the amyloid
proteins largely inhibited hatching and elicited reactive oxygen species,
which were effectively rescued by the inhibitor. Furthermore, Aβ-induced
damage to the mouse brain was mitigated in vivo with
the inhibitor. This study revealed the potential of Janus nanoparticles
as a new nanomedicine against a diverse range of amyloid diseases.
Objective: Obstructive sleep apnea (OSA) results in increased carotid intima-media thickness (IMT) and arterial stiffness; however, the association between adipocytokines and IMT/arterial stiffness in OSA patients is unclear.
Methods:We enrolled 95 normal weight and overweight, not obese, participants from May 2018 to December 2018 in this study. All subjects underwent a carotid artery ultrasound examination and polysomnography. Blood samples were used to determine serum chemerin, adiponectin, SFRP5, and apelin levels. Correlations between two quantitative variables were assessed using the Pearson or Spearman coefficient.Stepwise models of multiple linear regression analysis were performed to assess the independent relationships.Result: IMT in OSA patients was significantly higher than in the non-snorers. There were significant differences in the arterial stiffness parameters such as distensibility coefficient (DC), compliance coefficient (CC), and pulse wave velocity (PWV). SFRP5 level was lower in OSA patients than in non-snorers. Adiponectin correlated with CC, DC, and PWV among OSA patients; however, the relationship disappeared after a multivariable adjustment. Age was independently associated with all quantitative IMT and stiffness indices. AHI and minimum oxygen saturation (Mini SaO 2 ) were independently related to arterial stiffness.
Conclusion:The quantitative IMT and carotid arterial elasticity were significantly worse among OSA patients. Age was the main independent factor correlated with quantitative IMT and arterial stiffness, and AHI and mini SaO 2 were associated factors. There were no relationships between aforementioned adipocytokines and quantitative IMT/carotid arterial stiffness.
