Performance evaluation of a Ga(n,γ)Ga reaction-based epithermal neutron flux detector at an AB-BNCT device.

The Ga(n,γ)Ga reaction-based epithermal neutron flux detectors are novel instruments developed to measure the epithermal neutron flux of boron neutron capture therapy (BNCT) treatment beams. In this study, a spherical epithermal neutron flux detector using Ga(n,γ)Ga reaction was prototyped. The performance of the detector was experimentally evaluated at an accelerator-based BNCT (AB-BNCT) device developed by Lanzhou University, China.

Arbuscular Mycorrhizal Fungi Can Inhibit the Allocation of Microplastics from Crop Roots to Aboveground Edible Parts.

Microplastics are emerging pollutants that threaten soil health and food safety. Recently, there has been increasing interest in understanding the behavior of these particles in the rhizosphere, specifically regarding the potential uptake of microplastics into crops. Arbuscular mycorrhizal (AM) fungi are widespread soil fungi, forming symbiotic associations with most terrestrial plants.

Arbuscular Mycorrhizal Fungi Induced Plant Resistance against Fusarium Wilt in Jasmonate Biosynthesis Defective Mutant and Wild Type of Tomato.

Arbuscular mycorrhizal (AM) fungi can form mutual symbiotic associations with most terrestrial plants and improve the resistance of host plants against pathogens. However, the bioprotection provided by AM fungi can depend on the host-fungus combinations. In this study, we unraveled the effects of pre-inoculation with AM fungus on plant resistance against the hemibiotrophic fungal pathogen in jasmonate (JA) biosynthesis mutant tomato, () and the wild type Castlemart (CM).

E2F1 transactivates IQGAP3 and promotes proliferation of hepatocellular carcinoma cells through IQGAP3-mediated PKC-alpha activation.

For decades, E2F1 has been recognized as a retinoblastoma protein (RB) binding transcription factor that regulates the cell cycle. E2F1 binds preferentially to RB and accelerates the cell cycle in most cancer cells. However, it is thought that E2F1 modulates cell proliferation in other ways as well.

Iodine-mediated regioselective C2-amination of indoles and a concise total synthesis of (±)-folicanthine.

Highly substituted 2-aminated indoles can be prepared in moderate to excellent yields by regioselective C2-amination of indoles promoted by iodine. As a key step in a concise synthesis of (±)-folicanthine, its core structure was easily obtained by one step cyclization-dimerization of substituted tryptophan in high yield on a gram scale.

Iodine-induced regioselective C-C and C-N bonds formation of N-protected indoles.

A mild, metal-free, and environmently benign iodine-promoted regioselective C-C and C-N bonds formation of N-protected indole derivatives giving 2,3'-biindoles 2 and 4-(1H-indol-2-yl)morpholines 4 is successfully demonstrated. Various bioactive 2,3'-biindoles and 4-(1H-indol-2-yl)morpholines, bearing electron-rich to moderately electron-poor substituents, can be prepared in moderate to good yields.
