Kunth Extract Is a Novel Natural Drug against .

As a widely distributed plant in Northeast China, Kunth (CMK) is generally considered to have antibacterial properties; however, there is a lack of scientific evidence for this. Therefore, we investigated the chemical composition of CMK extract and its effect against A total of 105 compounds were identified in the alcohol extracts of CMK by UPLC-Q-TOF-MS. Most were flavonoids, with being the most represented.

Comparative Analysis of Herbaceous and Woody Cell Wall Digestibility by Pathogenic Fungi.

Fungal pathogens have evolved combinations of plant cell-wall-degrading enzymes (PCWDEs) to deconstruct host plant cell walls (PCWs). An understanding of this process is hoped to create a basis for improving plant biomass conversion efficiency into sustainable biofuels and bioproducts. Here, an approach integrating enzyme activity assay, biomass pretreatment, field emission scanning electron microscopy (FESEM), and genomic analysis of PCWDEs were applied to examine digestibility or degradability of selected woody and herbaceous biomass by pathogenic fungi.

KLn(MoO) micro/nanocrystals (Ln = La-Lu, Y): systematic hydrothermal crystallization, structure, and the performance of doped Eu for optical thermometry.

Systematic crystallization of KLn(MoO) double molybdate micro/nanocrystals was achieved in this work for the family of lanthanide elements (excluding Pm) and Y hydrothermal reaction under the optimized conditions of pH = 7, Mo/Ln molar ratio = 5 and 200 °C, with which the intrinsic influence of lanthanide contraction on phase preference, crystallite morphology (size/shape) and crystal structure was clearly revealed. Extended synthesis also produced KLaEu(MoO) (KLM:Eu) and KYEu(MoO) (KYM:Eu) red phosphors, and detailed spectral analysis found that the layered structure of orthorhombic KYM allows Eu to have a high quenching content of ∼70 at% ( = 0.7) and higher quantum efficiency and thermal stability of luminescence.

Impacts of climate change on water resources in the major countries along the Belt and Road.

Background: Climate change has altered global hydrological cycles mainly due to changes in temperature and precipitation, which may exacerbate the global and regional water shortage issues, especially in the countries along the Belt and Road (B&R).

Methods: In this paper, we assessed water supply, demand, and stress under three climate change scenarios in the major countries along the Belt and Road. We ensembled ten Global Climate Model (GCM) runoff data and downscaled it to a finer resolution of 0.

On the role of Zr substitution in structure modification and photoluminescence of LiLa(TaZr)O:Eu garnet phosphors.

Solid-state reaction at 1000 °C produces a series of Li-stuffed Li5+2x(La1-yEuy)3(Ta1-xZrx)2O12 garnet phosphors (x = 0-1, y = 0.05-0.6) that exhibit favorable efficiency and thermal stability for red luminescence under either blue or n-UV light excitation, where the optimal composition was identified to be x = 0.

Microfluidic-Based Mechanical Phenotyping of Androgen-Sensitive and Non-sensitive Prostate Cancer Cells Lines.

Cell mechanical properties have been identified to characterize cells pathologic states. Here, we report our work on high-throughput mechanical phenotyping of androgen-sensitive and non-sensitive human prostate cancer cell lines based on a morphological rheological microfluidic method. The theory for extracting cells' elastic modulus from their deformation and area, and the used experimental parameters were analyzed.

Active Return-to-Center Control Based on Torque and Angle Sensors for Electric Power Steering Systems.

This paper presents a complete control strategy of the active return-to-center (RTC) control for electric power steering (EPS) systems. We first establish the mathematical model of the EPS system and analyze the source and influence of the self-aligning torque (SAT). Second, based on the feedback signals of steering column torque and steering wheel angle, we give the trigger conditions of a state switch between the steering assist state and the RTC state.

Formation and characteristics of aqueous two-phase systems formed by a cationic surfactant and a series of ionic liquids.

Aqueous two-phase systems (ATPS) were obtained in the aqueous mixtures of a cationic surfactant and a series of ionic liquids (ILs). The effects of IL structure, temperature and additives on the phase separation were systematically investigated. The microstructures of some ATPS were observed by freeze-fracture replication technique.

[A new method to extract time-frequency characteristics of hypertension pathological signal based on pseudo Wigner-Ville distribution].

Hypertension, as one of diseases with the highest incidence in the world at present, is an important cause of stroke, coronary heart disease, renal insufficiency and other serious diseases. Based on pseudo Wigner-Ville distribution, this paper makes an analysis on the relevant pulse characteristics by measuring time range of the energy concentration circle. In view of the present situation, that is, about half of the high-normal blood pressure persons are likely to develop hypertension, we explored the pulse characteristics to find the pathological changes in subjects with prehypertension, in order to solve the problems that there are no obvious clinical significant features in prehypertension.

2-Hy-droxy-N,N,N-trimethyl-3-tetra-decyl-oxypropan-1-aminium bromide.

In the crystal structure of the title compound, C(20)H(44)NO(2) (+)·Br(-), the cation and anion are connected via an O-H⋯Br hydrogen bond, forming an ionic pair. The cation is disordered over two conformations related by a mirror plane, and the anion is situated on a mirror plane so that the asymmetric unit contains half of the ionic pair. The long alkyl chain in the cation adopts an all-trans conformation.

[The feature extraction of hypertension based on wavelet transform].

This paper carries out the multi-scale decomposition of pulse signals on different frequency bands by wavelet transform, and the analysis of power spectral density shows that the detailed signal energy of the fourth layer mainly concentrates on the 3-5 Hz, while the energy of the fifth layer concentrating on the 1-3 Hz. Through calculating the energy, the experimental results show that: the hypertension signal energy of 3-5 Hz band increases significantly, compared with the normal signals.
