[Objectives] The paper aimed to study the effects of new herbicidal compounds derived from TSC-3, Taiwanin Hand Taiwanin E on the redox potential of Arabidopsis root tip cells. [Methods] The effects of different concentrations of new herbicides on the redox potential of root cap, meristematic zone, transition zone and elongation zone of Arabidopsis thaliana were determined by using mt-roGFPI A. transgenic. [Results] Different concentrations of TSC-3, Taiwanin H and Taiwanin E could reduce the redox potential of root tip cells of the mt-roGFP1 labeled transgenic Arabidopsis thaliana plants, with the increase of the concentration of the compound, the greater the effect on the redox potential of the meristem zone of mt-roGFPI labeled transgenic A. thaliana plants. After being treated with TSC-3 at 0.1,1,5 and 10 µg mL-1 the mean values of the maximum variation in redox potential changes in root cells of the meristem zone were 13.06, 18.59, 27.74 and 29.92 mV, respectively. When treated with Taiwanin H and Taiwanin E at 1, -1 5 and 10 µg mL-1, the mean values of the maximum variation of redox potential in root cells of the meristem zone were 12.21, 15.72, 22.67 mV and 14.71, 24.03, 28.69 mV, respectively. [Conclusions] In a certain range, the greater the concentration of TSC-3, Taiwanin H and Taiwanin E, the greater of the redox potential changes in root cells of the meristem zone. It indicated that the redox potential response of A. thaliana root tip cells to these herbicidal compounds was dose-response related. Our results provide a basis for the study of the mechanism of novel plant-derived herbicides on root cell mitochondria by roGFPI fluorescence probe technology, and they also provide theoretical basis for the establishment of a rapid screening platform for herbicidal compounds.

In order to accurately obtain the deflagration characteristic parameters of methane-air mixtures under different ambient humidity conditions, a 20 L spherical explosion vessel analysis model was established by using fluid dynamics software Fluidyn. The deflagration process of methane-air mixture was solved by changing the initial humidity in the model. The results showed that under the same ambient humidity conditions, with the increase of methane concentration, the maximum deflagration pressure and flame propagation speed both showed a trend of first increasing and then decreasing, and reached a peak near the equivalent concentration. Under the same methane concentration conditions, the increase in ambient humidity caused the peak deflagration pressure and flame propagation speed of the methane-air mixture to decrease, and extended the time to reach the maximum deflagration pressure and the time for the flame to propagate to the corresponding monitoring point. It can be seen that the increase of ambient humidity can reduce the explosion intensity of methane and prevent the flame spread to a certain extent, which can inhibit the deflagration of methane-air mixture. The overall performance is that the higher the ambient humidity is, the more significant the deflagration inhibition effect will be [ABSTRACT FROM AUTHOR]

Objective To investigate the relationship between the growth regulation by estrogen in breast cancer 1 (GREB1) gene polymorphism and the incidence of osteoporotic fracture in Beijing senile population． Methods A total of 226 elderly patients were recruited and divided into fracture group (with osteoporotic fracture，n = 100) and control group (without osteoporosis and fracture，n = 126) ． The bone mineral density (BMD) of hip and lumbar spine were measured using a dual-energy X-ray bone densitometer． The genotype of GREB1 gene rs10929757 and rs5020877 locus were examined by Snapshot technique． Allele frequency and genotype frequency at both locus were compared． The patients'BMD values of different genotype at both locus were compared． Results Between the two groups，there were no statistical differences in the distribution of allele frequency and genotype frequency at both locus (P > 0. 05) ． Between the two groups of males，the C allele frequencies at rs10929757 locus were 36. 5% in the fracture group and 52. 2% in the control group，respectively，with statistical differences (P < 0. 05) ; there were no statistical differences in the allele frequencies of rs5020877 locus (P > 0. 05) ． Between the two groups of females，there were no statistical differences in the allele frequencies of both locus (P > 0. 05) ． When comparing patients'BMD values，at rs10929757 locus，there were no statistical differences among different genotypes in the whole sample，males and females; at rs5020877 locus， there were no statistical differences among different genotypes in the whole sample，males，and females． Conclusion The polymorphism of rs10929757 is associated with vertebral osteoporotic fracture in Beijing senile male population． The polymorphism of rs5020877 is not associated with vertebral osteoporotic fracture in Beijing senile population． [ABSTRACT FROM AUTHOR]

The uniaxial static and dynamic loading experiments wereexecuted by using MTS-C64. 106 press. Mechanical properties, rock burst performance, AE feature, dynamic failure feature and fractal dimension feature of coal mass were investigated by combining the monitoring results of PIC-2 and high-speed camera. Along with the increase of dynamic loading strain rate, the coal mass strength increased by following a logarithmic function, and the rock burst danger also increased. The disturbed energy input rate, the amount of AE and strike inccidents varied as "increase slowly increase rapidly-increase suddenly". Failure form of coal mass experienced a "shear failure-vertical splitting failureburst failure". It showed a quadratic relationship between the fractal dimension of fragments and dynamic loading strain rate. There must be a dynamic loading strain rate, which achieves the strongest rock burst, and it is 2. 8×10-3 s-1 according to the experiment results. [ABSTRACT FROM AUTHOR]

The variation of strain rate, dynamic mechanical properties and deformation and failure characteristics of coal/rock samples under different impact velocities were investigated by the Split Hopkinson pressure bar( SHPB) test system, and a coal and rock dynamic mechanics constitutive model was discussed. The results show that there is a positive correlation between the loading strain rate and the impact velocity of coal/rock samples, and the coal/rock samples have obvious phased mechanical response characteristics under different impact velocities. According to the difference of impact velocity, the stress-strain curves are divided into three types of compact deformation, plastic deformation, plastic softening deformation or plastic hardening deformation. In addition, the fracture characteristics of coal/rock samples all have significant strain rate dependence.Under low impact velocity, the samples are in the form of brittle failure. With the increase of impact velocity, the ductile fracture characteristics of samples gradually appear.Besides, based on the stress-strain constitutive relations and dynamic failure characteristics of coal/rock samples, a viscoelastic damage constitutive model with low-medium-high strain rate response was proposed. The results of numerical simulation show that the simulated curve has a good fitting accuracy with the measured curve, which proves the validity and rationality of the viscoelastic damage constitutive model with low-medium-high strain rate response.
