Summary: Antifungal proteins (AFPs) produced by Penicillium expansum showed different antifungal profiles and fruit protection effects. By solving the crystal structure of PeAfpB and designing five PeAfpA::PeAfpB chimeras, researchers found that the man-noproteins determined the protein interaction with the cell wall and its antifungal activity, while the binding to membrane phospholipids did not directly correlate with activity. This work provides insights into the feasibility of modifying protein specificity through rational design of chimeras with biotechnological applicability.

Summary: As a popular medicinal plant, Angelica dahurica has garnered attention in herbal medicine due to its active compounds, furanocoumarins (FCs), which have antioxidant, anti-tumor, and anti-virus activities. However, the enzymes responsible for the biosynthesis of FCs have not been identified. This study screened six prenyltransferase-coding sequences and identified two C-PTs (AdPT1, 2) and one O-PT (AdPT3) that are involved in the conversion of different compounds. The study also conducted structural analysis and mutagenesis experiments, revealing important amino acids for the activity of AdPT1. This study provides insights into the biosynthetic pathways of FCs in A. dahurica for further evolutionary studies.

Summary: In this study, a bisamidation strategy was applied to improve the therapeutic properties of Amphotericin B (AMB) by suppressing self-aggregation. Modifying the basic amino groups at the C16 amide residue enhanced the activity, while introducing lipophilic fragments reduced toxicity. N-methyl-amino acetyl and amino acetyl moieties at the C3' amide helped maintain fungistatic effectiveness. The modified compound 36 exhibited stronger antifungal efficacy and lower toxicity, making it a promising candidate for further development as a second-generation polyene antifungal agent.

Summary: In this study, a novel improvement on ladder line structure called longitudinally slotted structure is proposed, which increases the cross-sectional area of the electron beam and effective interaction area, thereby significantly improving the output power. The dispersion characteristics and field distribution of the slotted structure are analyzed through numerical and simulation calculations, and the optimal parameters are determined. A 94-GHz 2-D slotted structure EIO is designed and compared with the ladder line, it shows a 52.5% increase in cavity characteristic impedance $\textit{R}$ / $\textit{Q}$ and a 21.1% increase in output power. This new structure is expected to provide a new idea for power enhancement in millimeter-wave and terahertz EIOs.

Summary: A novel method for extracting and amplifying the third harmonic of an electron beam to generate high-power terahertz radiation is presented. This approach utilizes three planar grating structures operating in the backwave region to extract and amplify the electron beam from the fundamental modulation, resulting in an amplified output of the fundamental wave and a high power output of the fundamental triplet frequency. The planar grating structure is easier to machine and assemble compared to conventional harmonic amplifiers and allows for increased electron beam flow rate.

Summary: We investigate the electronic and optical properties of different stacked configurations of bilayer black phosphorus quantum dots. Our results show that the energy levels are influenced by the stacking configurations. The AC-stacked and unsymmetrical AB-stacked black phosphorus bilayers enhance optical transitions and realize dark-to-bright transitions in the absorption spectra. The coupling strength of edge states differs between configurations, providing a feasible approach to modulating the electronic and optical properties of bilayer black phosphorus.

Summary: Experimental investigations have been carried out on a 0.66-THz gyrotron, with the magnetic injection gun and the gyrotron beam-wave interaction cavity being designed and optimized. The gyrotron cavity incorporates a traditional three-section design. The experimental results demonstrate stable operation at the second cyclotron harmonic, with the gyrotron operating in the TE14,5 mode and a pulselength of 80 mu s. By adjusting the beam energy and magnetic field, the gyrotron achieves a maximum frequency of 656.95 GHz and an output power of 282 W. Additionally, the gyrotron can be used as a frequency-tunable source, with a tunable range of approximately 70 MHz. This gyrotron is specifically designed for irradiating THz waves on living bodies.

Summary: A novel high-frequency structure was proposed, which involved vertically placing four conventional ladder-line slow wave structures to form a four-sheet-beam orthogonal interconnection structure. The simulation results showed the achievement of an output power of over 500 W for a 0.22-THz wave with four sheet beams at 16.6 kV and each current of 0.8 A. This structure provides an alternative for the development of terahertz EIOs.

Summary: Long noncoding RNAs (lncRNAs) have been recently found to play a key role in various types of cancer. In this study, we identified a lncRNA LINC01094 that is associated with the metastasis of gastric cancer (GC) through next-generation sequencing. High expression of LINC01094 is linked to advanced T and N stages and poor prognosis in GC patients. We demonstrated that LINC01094 promotes the proliferation and metastasis of GC both in vitro and in vivo. Furthermore, we discovered that LINC01094 interacts with AZGP1, leading to downregulation of PTEN expression and activation of the AKT pathway.

Summary: This paper discusses the Sobolev type weak solutions of a certain class of second order quasilinear parabolic partial differential equations (PDEs). It provides a probabilistic interpretation for the weak solutions by using a family of coupled forward-backward stochastic differential equations (FBSDEs) that satisfy the monotonous assumption. The existence of weak solutions is proven based on the classical solutions of a family of PDEs approximating the weak solutions of the quasilinear PDEs. The uniqueness of the weak solutions is obtained through the principle of norm equivalence linking FBSDEs and PDEs.
