COMPARISON OF CATALYTIC REACTIVITIES OF TRIPHENYL－PHOSPHINE COMPLEXES OF Ru，Rh，Pd，Fe，Co，Ni IN THE MALEIC ANHYDRIDE HYDROGENATION

The Sequence of homogeneous catalytic reactivity of triphenylphosphine complexes of Ru, Rh, Pd, Fe, Co, Ni in the maleic anhydride hydrogenation is:Rucl2 (PPh3)3> RhCI (PPh3)3> NiCI2 (PPh3)2>CoCl2 (PPh3) 2> FeCI2 (PPh3) 2>pdcl2(PPh3)2. This is consistent with the metal atoms' ionization potentials.

Cbl-b and PI3K/Akt pathway are differently involved in oxygen- glucose deprivation preconditioning in PC12 cells

Background Transient sublethal ischemia is known as ischemic preconditioning, which enables cells and tissues to survive subsequent prolonged lethal ischemic injury. Ischemic preconditioning exerts neuroprotection through phosphatidylinositol 3-kinase （PI3K）/Akt pathway. Cbl-b belongs to the Casitas B-lineage lymphoma （Cbl） family, and it can regulate the cell signal transduction.The roles of ubiquitin ligase Cbl-b and PI3K/Akt pathway and the relationship between them in oxygen-glucose deprivation preconditioninq （OGDPC） in PC12 cells were investiaated in the ore.~e.nt study

Number of J/ψ events at BESIII

Using inclusive decays of J/ψ aprecise determination of the number of J/ψ events collected with the BESIII detector was performed.For the two data sets taken in 2009 and 2012,the numbers of J/ψ events were recalculated to be(224.0±1.3)×10^(6) and(1088.5±4.4)×10^(6),respectively;these numbers are in good agreement with the previous measurements. For the J/ψ sample taken in 2017-2019,the number of events was determined to be(8774.0±39.4)×10^(6).The total number of J/ψ events collected with the BESIII detector was determined to be(10087±44)×10^(6),where the uncertainty is dominated by systematic effects,and the statistical uncertainty is negligible.
