Targeting Senescence with Apigenin Improves Chemotherapeutic Efficacy and Ameliorates Age‐Related Conditions in Mice

Advanced Science, EarlyView.
As a plant‐derived flavonoid, apigenin directly targets PRDX6 to inhibit its PLA2 activity, blocking HSPA8 activation and disturbing its interactions with ATM and p38MAPK in senescent cells. By dampening wide spectrum expression of the SASP, apigenin prevents loss of tissue homeostasis, improves organ function, and alleviates multiple age‐related ...

Single‐Cell and Spatial Transcriptomics Reveals a Stereoscopic Response of Rice Leaf Cells to Magnaporthe oryzae Infection

Advanced Science, EarlyView.
By employing a combination of single cell and spatial transcriptomic sequencing, this study presents a stereoscopic response of rice leaf to Magnaporthe oryzae infection. The vascular tissues mount defenses by producing phytoalexins. The immune strength is stronger toward the rice leaf tip than that of the leaf base.

A Single‐Stage Differential Amplifier Using Organic Electrochemical Transistors

Advanced Electronic Materials, EarlyView.
A three‐transistor differential amplifier using depletion‐mode organic electrochemical transistors is implemented that offers a common‐mode rejection ratio of up to ≈20 dB. Compared to a Wheatstone bridge amplifier, ECG recordings with this amplifier showed improved signal‐to‐noise ratio, gain, and power consumption.
