Background:Ischemia-reperfusion injury(IRI)poses a significant challenge to liver transplantation(LT).The underlying mechanism primarily involves overactivation of the immune *** shock protein 110(HSP110)functions as a molecular chaperone that helps stabilize protein ***:An IRI model was established by performing LT on Sprague-Dawley rats,and HSP110 was silenced using ***-eosin staining,TUNEL,immunohistochemistry,ELISA and liver enzyme analysis were performed to assess IRI following *** blotting and quantitative reverse transcription-polymerase chain reaction were conducted to investigate the pertinent molecular ***:Our findings revealed a significant increase in the expression of HSP110 at both the mRNA and protein levels in the rat liver following LT(P<0.05).However,when rats were injected with siRNAHSP110,IRI subsequent to LT was notably reduced(P<0.05).Additionally,the levels of liver enzymes and inflammatory chemokines in rat serum were significantly reduced(P<0.05).Silencing HSP110 with siRNA resulted in a marked decrease in M1-type polarization of Kupffer cells in the liver and downregulated the NF-κB pathway in the liver(P<0.05).Conclusions:HSP110 in the liver promotes IRI after LT in rats by activating the NF-κB pathway and inducing M1-type polarization of Kupffer *** HSP110 to prevent IRI after LT may represent a promising new approach for the treatment of LT-associated IRI.

High-order nonlinear multiphoton absorption is usually inefficient,but can be enhanced by designing resonant excitations between occupied and unoccupied energy *** conducted angle-resolved multi-photon photoemission(mPPE)studies on the SnSe_(2)(001)surfaces excited by ultrashort laser *** tuning photon energy and light polarization,we demonstrate the presence of a resonant four-photon photoemission(4PPE)process involving the occupied valence band(VB),the unoccupied second conduction band(CB2)and the unoccupied image-potential state(IPs)of SnSe_(2).In this 4PPE process,VB electrons of SnSe_(2) are resonantly excited into CB2 by adsorbing two photons,followed by the adsorption of another photon to populate the n=1 IPs before being emitted out to the vacuum by adsorbing one more *** results in a double-resonant 4PPE process,which exhibits approximately a 40 times enhancement in photoemission yields compared to cases where one of the resonant pathways,CB2→IPs,is inhibited by involving a virtual state instead of the IPs in the *** double-resonant 4PPE process efficiently excite the bulk VB electrons outside the vacuum,like taking advantage of resonant“ladders”through two real empty electronic states of SnSe_(2).Our results highlight the important applications of mPPE in probing the band-structure,particularly the unoccupied states,of recently emerging main group dichalcogenide ***,the discovered resonant mPPE process contributes to the exploration of their promising optoelectronic applications.

It is very common for similar granitoids to be emplaced in the same tectonic region， with some being metal-fertilized while others are barren. The reasons for this are still not clear. Here， we take the Shangcheng pluton as an example. This pluton occurs close to the giant Shapinggou porphyry Mo deposit， and we use amphibole and biotite geochemistry as sensitive tracers to explore this issue. The Shangcheng granitoids comprise the Sigudun （SGD） and Shiguwa （SGW） units， with emplacement ages ranging from 140 ± 3 Ma to 134 ± 2.4 Ma， as revealed by titanite U-Pb dating. The geochemical data of amphibole and biotite indicate that the magma intruded from depths of ～3.3 km to ～2.3 km with increasing oxygen fugacity. The modeled results indicate that water content is an essential factor for metal fertilization， as the Shangcheng pluton has a lower water content than the Shapinggou Mo-bearing granite. The Shangcheng pluton is also characterized by fluorine-poor conditions， with lower halogen fugacity values of IV（F） and log (f H2O/f HF)fluid. In contrast， the increasing Y/Ho and Nb/Ta ratios of the Shapinggou Mo-bearing granite indicate the F-rich nature of the fertilized Shapinggou magma， and its lower Zr/Hf and K/Rb ratios suggest a greater magma differentiation. Therefore， water-poor and F-poor magma， in combination with low-degree fractional crystallization， may be the major controlling factors responsible for the Mo-barren nature of the Shangcheng pluton.
