Advanced multimetabolic APTw-CEST and 2-deoxy-D-glucose-CEST postprocessing metrics allowed adequate preclinical murine BC subtyping. AREX showed potential for 2-deoxy-D-glucose-CEST in tumor characterization; however, APTw-CEST remains superior. MTRasym failed to distinguish between tumor subtypes in CEST-MRI.
Our findings unveil a brain-cartilage circuit that regulates cartilage regeneration, providing valuable insights into the inherent limitations of tissue regeneration and suggesting a promising treatment strategy for enhancing cartilage regeneration.
The IDH1-wt group showed higher amplitude of MMN evoked by novel stimulus at Fz and Cz and longer latency of the P300 component evoked by a deviant stimulus at Fz. The combination of AERP parameters yielded a more effective means to predict IDH1 mutation status in patients with insular glioma, which may provide guidance for the surgical intervention of this disease.
We also identified and characterised a PARP1 mutation resulting in loss of the enzymatic inhibition and trapping activity of the PARP1-selective inhibitor, saruparib. However, the same mutation increased the trapping ability of other PARPi, namely veliparib and olaparib, without enhancing their enzymatic inhibition activity, a change that led to an increase in efficacy in this BRCA1m model. Together, these data suggest that PARP1 trapping, and not only its enzymatic inhibition, is a key driver for PARPi effectiveness in BRCA1m cancer cells.

Both MA and 2 mA EA (not 3, 4, 6 mA EA) stimulation of ST37 have a similar analgesic effect in acute inflammatory visceral pain rats, which may be related to their function in suppressing the activities of α7nAChR/PI3K/AKT signaling pathway.
