Clinical significance and potential mechanism of AEBP1 in glioblastoma.

Glioblastomas (GBM), the most common primary brain tumor, lack accurate prognostic markers and have a poor prognosis. Our study was designed to identify effective biomarkers for GBM prognosis analysis and development of precise treatments. Differentially expressed genes (DEGs) between GBM patients and controls were analyzed from the Xena database and GEPIA.

Manipulation of Giant Multipole Resonances via Vortex γ Photons.

Traditional photonuclear reactions primarily excite giant dipole resonances, making the measurement of isovector giant resonances with higher multipolarities a great challenge. In this Letter, the manipulation of collective excitations of different multipole transitions in even-even nuclei via vortex γ photons is investigated. We develop the calculation method for photonuclear cross sections induced by the vortex γ photon beam using the fully self-consistent random-phase approximation plus particle-vibration coupling (RPA+PVC) model based on Skyrme density functional.

Generation of High-Density High-Polarization Positrons via Single-Shot Strong Laser-Foil Interaction.

We put forward a novel method for producing ultrarelativistic high-density high-polarization positrons through a single-shot interaction of a strong laser with a tilted solid foil. In our method, the driving laser ionizes the target, and the emitted electrons are accelerated and subsequently generate abundant γ photons via the nonlinear Compton scattering, dominated by the laser. These γ photons then generate polarized positrons via the nonlinear Breit-Wheeler process, dominated by a strong self-generated quasistatic magnetic field B^{S}.

Direct calibration of neutron detectors for laser-driven nuclear reaction experiments with a gated neutron source.

Nowadays, the sustained technological progress in high-intensity lasers is opening up the possibility of super-intense laser pulses to trigger or substantially influence nuclear reactions. However, it is a big challenge to quantitatively measure the reaction products because of the interference of electromagnetic pulses induced by high-intensity lasers. Fast scintillation detectors are widely chosen for fast neutron detection.

Brilliant circularly polarized γ-ray sources via single-shot laser plasma interaction.

Circularly polarized (CP) γ-ray sources are versatile for broad applications in nuclear physics, high-energy physics, and astrophysics. The laser-plasma based particle accelerators provide accessibility for much higher flux γ-ray sources than conventional approaches, in which, however, the circular polarization properties of the emitted γ-photons are usually neglected. In this Letter, we show that brilliant CP γ-ray beams can be generated via the combination of laser plasma wakefield acceleration and plasma mirror techniques.

A novel selected force controlling method for improving robotic grinding accuracy of complex curved blade.

Nonlinear time-varying contact state is a crucial factor to prevent the traditional robotic belt grinding method from precision machining of blade. In this case, a novel selected force controlling method (SFC) with consideration of regional division (RD) based on machining allowance is proposed for improving robotic grinding accuracy of complex curved blade, on basis of the self-developed adaptive impedance controller. Ideal normal grinding force at each cutter-contact (CC) point is calculated by principal curvature radius and regional allowance of blade surface.

Comparison of the proteome of isoniazid-resistant and -susceptible strains of Mycobacterium tuberculosis.

In an effort to determine whether there is a major difference in protein level between isoniazid resistant and susceptible Mycobacterium tuberculosis strains, the proteins extracted from nine isoniazid (INH) monoresistant M. tuberculosis strains, seven isoniazid susceptible M. tuberculosis strains, and M.

Identification of unique genetic markers in Rv0927c among Mycobacterium tuberculosis W-Beijing strains.

Fifty-six clinical isolates of Mycobacterium tuberculosis were analyzed by spoligotyping to determine the prevalence of W-Beijing strains. Forty-nine of the 56 isolates belonged to W-Beijing strains and 7 isolates were non-Beijing strains. Comparative two-dimensional gel electrophoresis analysis of protein patterns between the W-Beijing and non-Beijing strains identified a unique protein Rv0927c that is absent in the former but present in the latter and the reference strain M.

[Expression and purification of Rv3369 of Mycobacterium tuberculosis].

To obtain purified recombinant Rv3369 protein by means of expressing the Rv3369 protein of Mycobacterium tuberculosis in E. coli. The gene coding Rv3369 protein was amplified by polymerase chain reaction (PCR), then was inserted into an expression vector pET28a to get recombinant plasmid.
