Abstract: The present invention relates to a preparation method for and an application of a chiral spirocyclic phosphine-nitrogen-phosphine tridentate ligand SpiroPNP and an iridium catalyst Ir-SpiroPNP thereof. The chiral spirocyclic phosphine-nitrogen-phosphine tridentate ligand is a compound represented by formula I, or a racemate or optical isomer thereof or a catalytically acceptable salt thereof; and the main structural feature is a phosphine ligand having a chiral spiro indene skeleton and a large sterically hindered substituent. The chiral spirocyclic phosphine-nitrogen-phosphine tridentate ligand can be synthesized into a chiral starting material from a 7-diaryl/alkylphosphino-7?-amino-1,1?-spirodihydroindenyl compound having a spiro ring skeleton. The iridium catalyst of the chiral spirocyclic phosphino-7?-amino-1,1?-spirodihydroindenyl compound having a spiro ring skeleton.

Abstract: The present invention discloses a compound microbial fertilizer, comprising citric acid fermentation raffinate, Arthrobacter fermentation liquid, urea, monoammonium phosphate and potassium sulphate; the proportion of each component is: (400-600) mL:(400-600) mL:(50-80) g:(50-80) g:(40-60) g; and the pH value of the compound microbial fertilizer is adjusted to 5.5-7.0 with ammonia water. The fertilizer can increase crop yield, promote crop growth, and improve the soil.

Abstract: Compounds, pharmaceutical compositions and methods are provided for reprogramming M2-like macrophages to M1-like macrophages, which reverses the antifibrotic to profibrotic shift observed during the course of fibrotic diseases and certain cancers. The compounds comprise an immune modulator that targets a pattern recognition receptor of a cell and are specific to the cells of interest through the incorporation of a targeting moiety (e.g., folate or a functional fragment or analog thereof). Releasable and/or non-releasable linkers can be included and engineered to facilitate the optimal delivery of the immune modulator. The compounds and compositions can be employed in one or more methods of treatment for fibrotic diseases and/or cancers.

Abstract: A wiring apparatus for a communication pipeline includes a frame and wheels arranged on the frame in pairs. A control motor for driving the wheels to rotate is arranged on the frame, at least one pair of wheels are rotatably connected to the frame, a recessed wire clamping cavity is arranged on an outer peripheral of the wheel, a channel configured for clamping an optical power cable is formed between two wheels arranged in pairs through the wire clamping cavity, and a hook (on which a wiring can be hung) is arranged at an end of the frame.

Abstract: Disclosed relates to an electrochemical determination system of glycated proteins, the system comprising: a filtering means for filtering labeled compounds bound to glycated proteins and non-glycated proteins after adding labeling compounds, capable of selectively binding to the glycated proteins to a solution, in which glycated/non-glycated proteins coexist, to be bound all to the glycated proteins; and a quantifying means for quantifying the filtered labeling compounds, not bound to the glycated proteins. The system of the present invention filters the residual labeled compounds left after binding to glycated proteins to quantify, instead of directly quantifying glycated proteins via the known glycated protein determination methods, thus simplifying the configuration of the system that can provide exact determinations with a low cost.

Abstract: A biosensor, for use in measurement of an analyte, includes a microporous membrane support, a first electrode system, a second electrode system, and a pair of insulating films. The first electrode system is formed on the surface of the microporous membrane support and the second electrode system is formed on the opposite surface of the microporous membrane support. The biosensor enables a rapid, simple, separation-free, and selective detection of the analytes. The biosensor does not require any bulky additional electrode, so that miniaturization, point-of-car testing, and disposability can be achieved.
