This study was aimed to examine the antiapoptotic effect of Ulmus davidiana extracts through regulation of the intracellular cation mobilization in U937 human monocytic cells. To investigate the modulatory effects on lipopolysaccharide-induced apoptosis and the Ca2+ signaling pathway, we measured the levels of intracellular Ca2+ and various protein markers such as Bax, Bcl-2, and PARP. To isolate biopotent molecules, the branches of U. davidiana were processed sequentially using 60% ethanol, supercritical fluid extraction, and ethyl acetate extraction of the remaining samples to obtain single fractions and catechin-glycoside, which is one of the known bioeffector molecules of U. davidiana. Lipopolysaccharide increased intracellular Ca2+ mobilization in U937 cells by inducing transient oscillations and markedly increased Bax and PARP protein expression and decreased Bcl-2 expression. All U. davidiana and catechin-glycoside significantly reduced lipopolysaccharide-induced intracellular Ca2+ mobilization and downregulated apoptosis-related molecules. These results suggest that U. davidiana and catechin-glycoside may be useful for improving immune system function.

“…Lignocellulosic biomass is one of the most abundant resources, which is a promising source of renewable energy ( Du et al, 2019 ; Liu et al, 2020a ; Wang H. et al, 2020 ; Liu et al, 2021b ; Liu et al, 2021c ). Lignocellulosic biomass is mainly composed of cellulose, hemicelluloses, and lignin ( Liu et al, 2020b ; Liu et al, 2020 ; Liu et al, 2021a ; Du et al, 2021b ; Liu et al, 2021d ; Wang et al, 2021 ). Hemicellulose is a polysaccharide composed of different types of monosaccharides such as xylose, arabinose, galactose, and so on.…”

The kinetics studies is of great importance for the understanding of the mechanism of hemicellulose pyrolysis and expanding the applications of hemicellulose. In the past years, rapid progress has been paid on the kinetics studies of hemicellulose hydrolysis. In this article, we first introduced the hydrolysis of hemicelluloses via various strategies such as autohydrolysis, dilute acid hydrolysis, catalytic hydrolysis, and enzymatic hydrolysis. Then, the history of kinetic models during hemicellulose hydrolysis was summarized. Special attention was paid to the oligosaccharides as intermediates or substrates, acid as catalyst, and thermogravimetric as analyzer method during the hemicellulose hydrolysis. Furthermore, the problems and suggestions of kinetic models during hemicellulose hydrolysis was provided. It expected that this article will favor the understanding of the mechanism of hemicellulose pyrolysis.

“…For example, Du et al reported a conductive PEDOT:PSS/CNFs paper electrodes for flexible supercapacitors with superior areal capacitance and cycling stability (Fig. 6 a) [ 144 ]. The supercapacitor could deliver the maximum areal specific capacitance of 854.4 mF cm −2 (corresponding to 122.1 F cm −3 ) at 5 mV s −1 and offer the highest areal energy density of 30.86 μWh cm −2 (corresponding to 4.41 mWh cm −3 ).…”

Cellulose nanopaper has shown great potential in diverse fields including optoelectronic devices, food packaging, biomedical application, and so forth, owing to their various advantages such as good flexibility, tunable light transmittance, high thermal stability, low thermal expansion coefficient, and superior mechanical properties. Herein, recent progress on the fabrication and applications of cellulose nanopaper is summarized and discussed based on the analyses of the latest studies. We begin with a brief introduction of the three types of nanocellulose: cellulose nanocrystals, cellulose nanofibrils and bacterial cellulose, recapitulating their differences in preparation and properties. Then, the main preparation methods of cellulose nanopaper including filtration method and casting method as well as the newly developed technology are systematically elaborated and compared. Furthermore, the advanced applications of cellulose nanopaper including energy storage, electronic devices, water treatment, and high-performance packaging materials were highlighted. Finally, the prospects and ongoing challenges of cellulose nanopaper were summarized.
