Abstract Psoriasis is a common immune‐mediated inflammatory skin disease, caused by disturbed interactions between keratinocytes and immune cells. Chinese medicine shows potential clinical application for its treatment. Liquiritin flavone compound extracted from licorice antitussive, antioxidant antiinflammatory effects, therefore may have as psoriasis therapeutic. The aim of this work was to examine the possible roles that liquiritin in treating psoriasis. HaCaT cells were stimulated TNF‐α...

D-Allulose 3-epimerase (DAE) can convert D-fructose into D-allulose, but its lower activity and poor thermal stability restrict application in industrial production. This study utilized a semi-rational design specific site mutations to enhance the enzyme of DAE from Clostridium scindens ATCC 35704 (Csc-DAE) at same time. Notably, activities six mutants (V22I, A25V, Q46I, C212N, G165A, G267D) orderly superimposed double-point were increased by 1.08–1.31 1.28–1.64 times that wild type (553.7...

Enzyme catalysis represents a promising approach for sustainable chemical synthesis, yet its industrial applications face limitations due to the inefficient regeneration and high cost of essential cofactors, such as adenosine-5′-triphosphate (ATP) nicotinamide adenine dinucleotide phosphate (NADPH). While natural metabolic systems efficiently recycle cofactors through spatially organized enzymes, replicating this efficiency in vitro remains challenging. Here, we prepare five-enzyme...

We studied the relationship between pressure ratio of buffer gases (argon and neon) rate coherent population trapping resonance frequency shift with cell temperature in Rb85. found that when total varies within range 5–15kPa, along a bell shaped curve. Every curve crossed horizontal axis at two points are roughly symmetrical respect to midpoint 1:1. This allows us minimize by adjusting these points.

We proposed a scheme to implement coherent population trapping (CPT) atomic clock based on the transient CPT phenomenon. proved that transmitted laser power in typical Λ system near resonance features as damping oscillation. Also, oscillating frequency is exactly equal detuning from hyperfine splitting. Therefore, we can directly measure and then compensated output of microwave oscillator get standard frequency. By this method, further simplify structure clock, make it easier be digitized...
