Thonningianin A derived from Penthorum chinense Pursh alleviates cerebral ischemia/reperfusion-mediated apoptosis and pyroptosis through the activation of PINK1/Parkin-dependent mitophagy [PDF]

open access: yesChinese Medicine
Background Cerebral ischemia/reperfusion injury (CI/RI) remains a critical barrier to effective ischemic stroke (IS) treatment. While mitophagy activation has been shown to attenuate apoptosis and pyroptosis, thereby ameliorating CI/RI, the therapeutic ...

A 3-3.7GHz Time-Difference Controlled Digital Fractional-N PLL With a High-Gain Time Amplifier for IoT Applications

open access: yesIEEE Access, 2022
This paper presents analyses of jitter and reference spur of a digital PLL using a phase-frequency detector (PFD) and a time amplifier (TA). In the PFD-TA PLL, the TA amplifies a phase error between a reference clock and a divided feedback clock.
