Extracellular Vesicles Derived from Lung Cancer Cells Induce Transformation of Normal Fibroblasts into Lung Cancer-Associated Fibroblasts and Promote Metastasis of Lung Cancer by Delivering lncRNA HOTAIR

Human lung cancer (lc) cells a549/h358, normal lung epithelial cells beas-2b, and lung normal fibroblasts (nfs) were cultured, followed by transfection of h358 cells with hotair sh rna.Extracellular vesicles (evs) extracted from h358 cells were identified.The internalization of dil-labeled-evs by nfs was tested, and protein levels of cancer-associated fibroblast (caf) surface markers, inflammatory cytokines, cell proliferation, invasion, and migration, and lnc rna hotair levels were determined.A549 cells were cultured in an h358-evs-treated conditioned medium of nfs (nfcm), followed by intravenous injection of a549 cells into nude mice.The lesions and ki-67-positive cells in lung tissues were measured.The results showed that tumor cell-derived evs (t-evs) motivated the transformation of nfs into cafs.Specifically, evs can be internalized by nfs, and the protein levels of caf surface markers and inflammation levels were elevated in h358-evs-treated nfs.The proliferation, invasion, and migration of a549 cells cultured in t-evs-treated nfcm were increased.H358-evs carried hotair into nfs and promoted the transformation of nfs into cafs.Inhibition of hotair partially reversed the promoting effect of h358-evs on the transformation of nfs into cafs and invasion and migration of lc cells.T-evs promoted metastasis of lc in vivo by transforming nfs into cafs.

The Relationship between Body Mass Index and Physical Activity Participation Rate Design Based on Fuzzy Breakpoint Regression Design

Obesity is a global public health problem in modern society.Body mass index (bmi) can measure whether a person’s body is in obesity and health.Body mass is the quality of human body, which is a comprehensive and relatively stable characteristic of human body structure, physiological function, and psychological factors, and body mass is the basis of heredity and acquisition.Physical exercise is a kind of physical activity that people do in their spare time in order to exercise their body and mind.In this paper, we take the physical health problem of obesity as the background and combine the fuzzy breakpoint regression method to design the body mass index and physical exercise participation rate.The relationship between the body mass index and physical exercise participation rate design based on fuzzy breakpoint regression in this paper is mainly discussed as follows: background: the obesity rate is rising and chronic diseases caused by obesity affect health; results: jumps were observed for body health indices above 24.9 kg/m2, while participation rates in physical activity decreased compared to the normal weight range; and conclusion: the greater the weight of the group, the less willingness to participate in physical activity and the lower the rate of participation in physical activity.

Application of Computer-Aided Precious Metal Materials in Electrochemistry of Ceramic Jewelry Design

In order to solve the electrochemical application of precious metal materials in ceramic jewelry design, a computer-aided design method of precious metal materials in ceramic jewelry was proposed.First, the potential energy surface analyzed in this paper is composed of the sum of disomy and trisomy, with different proportions of disomy and trisomy.Therefore, in the fitting process, the above two relations can be used to measure the contribution of the two-body term and the three-body term, respectively; secondly, from the viewpoint of lattice dynamics, precious metals are of special significance, because they are simple fcc lattice and large and pure single crystals can be obtained.Therefore, their accurate phonon dispersion curves can be obtained experimentally; finally, the phonon dispersion curves along the highly symmetric vector direction are given, and the calculated results are in good agreement with the experimental data.This shows that the new analytical potential energy surface accurately reproduces the interactions inside these crystals.The new analytical potential energy surfaces of the three noble metals correctly reproduce the macroscopic properties of the system, including elastic modulus, cohesive energy, and phonon dispersion curve, as well as important surface features.For all three systems, the order of the surface energies of the unreconstituted surfaces is (110) &gt; (100) &gt; (111), which is also correct.At the same time, the new potential energy surface gives the correct relaxation behavior of the unreconstituted surface.

Acoustic Control through Gradient Coil Design Using a Finite-Difference-Based Method for MRI

An acoustic control scheme is proposed in this paper through the process of gradient coil design for magnetic resonance imaging (mri).With a finite-difference-based method, the stream function and coil displacement caused by fast gradient switching can be unified by a simplified momentum equation, which can be incorporated into the conventional gradient coil design.A three-dimensional transverse gradient coil with an edge-connected cylindrical structure is used as a design example to verify the proposed design method.In addition, an acoustic model is established to simulate the sound pressure level (spl).in the model, two hemispherical air volumes are added flush with the ends of the cylindrical main magnet to mimic the free propagation of sound waves on the boundaries.The simulation results show that by optimizing coil displacement, the overall spl can be attenuated by 4 d b over the frequency range from 0 to 3000 hz with the displacement reduced by about 50%, at the cost of a figure of merit (fom) loss by about 8%.Therefore, the proposed acoustic control scheme can be used as a complement to conventional acoustic control methods for further noise reduction.

In order to improve the color saturation of textile structured chromogenic photonic crystals, this paper proposes that the dye adsorbed pst structural elements (reactive dyes/pst microspheres) on the outer surface can be used to construct electrochemically structured chromogenic photonic crystals on mulberry fabrics by digital printing.In this method, the adsorption conditions and adsorption model of dyes on the surface of pst colloidal microspheres were studied.The structure and morphology of reactive dyes/pst microspheres, the arrangement of the obtained photonic crystals, and the structural chromogenic effect were characterized.The results showed that the amount of dye adsorbed on the surface of microspheres increased significantly with the increase of adsorption temperature from 25°c to 65°c.When the adsorption temperature continued to rise to 75°c, the dye adsorption capacity on the surface of pst microspheres did not increase significantly.The adsorption model accords with the langmuir model; reactive dye/pst microspheres have a typical core-shell structure, and the particle size of the microspheres is slightly larger than that before adsorption.Conclusion.The reactive dye/pst photonic crystal chromogenic electrochemical structure constructed on the surface of white silk fabric has a regular and orderly arrangement of microspheres, showing bright structural color.
