Bulky Di(1-adamantyl)phosphinous Acid-Ligated Pd(II) Precatalysts for Suzuki Reactions of Unreactive Aryl Chlorides.

Di(1-adamantyl)phosphine oxide (SPO-Ad: AdP(V)(=O)H), a stable tautomer of di(1-adamantyl)phosphinous acid (PA-Ad: AdP(III)-OH), was employed to synthesize two new PA-Ad-coordinated complexes, POPd-Ad and POPd2-Ad. POPd-Ad was easily transformed from POPd2-Ad in acetonitrile, and the [M - H] ion of the deprotonated POPd-Ad was observed in the electrospray ionization-mass spectrum of POPd2-Ad. Both complexes are effective precatalysts for the Suzuki reaction of aryl chlorides.

The significance of coagulation and fibrinolysis-related parameters in predicting postoperative venous thrombosis in patients with breast cancer.

Background: To explore the expression level of coagulation and fibrinolysis-related indexes in the plasma of breast cancer patients after surgery, and explore their predictive value for deep venous thrombosis (DVT).

Methods: From May 2016 to May 2019, 63 patients with lower extremity DVT after radical mastectomy in our hospital were selected as the thrombus group, and 69 patients without venous thrombosis after radical mastectomy were selected as the control group. The levels of D-dimer (D-D) and fibrinolytic product (FDP) were measured by latex enhanced immunoturbidimetry, Fibrinogen (FIB) levels were measured using the von Clauss method, thrombin antithrombin complex (TAT) and thrombomodulin (TM) levels were measured by enzyme-linked immunosorbent assay (ELISA), and the evaluation value of coagulation markers on tumor thrombosis was analyzed by receiver operating characteristic curve (ROC) curve analysis.

NRF2 regulates the sensitivity of human NSCLC cells to cystine deprivation-induced ferroptosis via FOCAD-FAK signaling pathway.

Transcription factor nuclear factor-erythroid 2-like 2 (NRF2) mainly regulates cellular antioxidant response, redox homeostasis and metabolic balance. Our previous study illustrated the translational significance of NRF2-mediated transcriptional repression, and the transcription of FOCAD gene might be negatively regulated by NRF2. However, the detailed mechanism and the related significance remain unclear.
