First-principles insights into hydrogen trapping in interstitial-vacancy complexes in vanadium carbide.

Hydrogen trapping is a key factor in designing advanced vanadium alloys and steels, where the influence of carbon vacancies is still elusive. Herein we have investigated the effect of carbon vacancies on the hydrogen trapping of defect-complexes in vanadium carbide using first-principles calculations. When a carbon vacancy is present, the second nearest neighboring trigonal interstitial is a stable hydrogen trapping site.

TB-QUICK: CRISPR-Cas12b-assisted rapid and sensitive detection of Mycobacterium tuberculosis.

Objectives: Tuberculosis (TB) remains one of the public health problems worldwide. Rapid, sensitive and cost-effective diagnosis of Mycobacterium tuberculosis (M.tb) is critical for TB control.

[Spatial variability of soil C/N ratio and its influence factors at a county scale in hilly area of Mid-Sichuan Basin, Southwest China].

Spatial distribution characteristics of soil C/N ratio and its affecting factors at a county scale in hilly area of Middle Sichuan Basin were analyzed based on field sampling. Result indicated that soil C/N ranged from 4.84 to 21.

ScreenFect A: an efficient and low toxic liposome for gene delivery to mesenchymal stem cells.

Mesenchymal stem cells (MSCs) hold great promise in variety of therapeutic applications including tissue engineering and cancer therapy. Genetic modification of MSCs can be used to enhance the therapeutic effect of MSCs by facilitating a specific function or by transforming MSCs into more effective gene therapy tools. However, the successful generation of genetically modified MSCs is often limited by the poor transfection efficiency or high toxicity of available transfection reagents.

Activity of the antimicrobial peptide and thanatin analog S-thanatin on clinical isolates of Klebsiella pneumoniae resistant to conventional antibiotics with different structures.

The treatment of infections caused by bacteria resistant to the vast majority of antibiotics is a challenge worldwide. To evaluate the effect of S-thanatin (an analog of thanatin, a cationic antimicrobial peptide isolated from the hemipteran insect Podisus maculiventris) against microbial resistant to antibiotics, we studied its bactericidal kinetics, synergistic effect, resistance, and activity on clinical isolates of Klebsiella pneumoniae resistant to conventional antibiotics with different structures. The bactericidal rate of S-thanatin was more than 99% against K.
