Distinct Cleavage Trajectories Mediated by DNA and RNA Substrate in Argonaute From Methanocaldococcus Fervens

Advanced Science, EarlyView.
This study characterizes MfAgo, an enzyme exhibiting highly efficient DNA‐guided DNA and RNA cleavage capability. Precise RNA cleavage strictly requires dimerization to stabilize the PIWI‐loop region, while its robust DNA cleavage functions in a dimerization‐independent manner.

Investigation of the Effects of Hydrogen Addition on Explosion Characteristics and Pressure Fluctuations of Ethyl Acetate

Energies
This study systematically explored the characteristics of explosion and pressure fluctuations of ethyl acetate (EA)/hydrogen (H2)/air mixtures under different initial pressures (1–3 bar), H2 fractions (4%, 8%, 12%), and equivalence ratios of EA (0.5–1.4).

Restoring Endothelial Mitochondrial Homeostasis With a Bioactive Nanoshield Promotes Vascular Regeneration on Cardiovascular Implants

Advanced Science, EarlyView.
A bioactive poly(citrate‐polyglycol‐procyanidin) (PCGP) nanoshield is developed for cardiovascular implants to restore endothelial mitochondrial homeostasis following vascular injury. By preserving mitochondrial integrity, re‐establishing metabolic balance, and activating PI3K/Akt/eNOS‐NO signaling, the PCGP interface promotes functional endothelial ...

Sequential Regulation of Neurovascular Bone Regeneration in Large Bone Defects Using Black Phosphorus‐Europium Nanosheet Integrated TPMS Biomimetic Scaffold with Photo‐Controlled Ion Release

Advanced Science, EarlyView.
TPBE scaffolds, in conjunction with mild photothermal effects, effectively activate the PI3K/Akt signaling cascade, thereby promoting early neuronal differentiation and neurite growth. Short‐term (12 W) in vivo implantation studies revealed no significant pathological damage to major organs, providing preliminary evidence of the material's excellent ...

ROS‐Responsive Nanoparticle Delivery of Dexmedetomidine Protects the Gut Vascular Barrier After Intestinal Ischemia/Reperfusion via the HDAC‐H3K27ac‐TCF4 Axis

Advanced Science, EarlyView.
A low dose of dexmedetomidine, delivered by ROS‐responsive nanoparticles, preferentially accumulates in the ischemic intestine and restores gut vascular barrier integrity after ischemia/reperfusion injury. This nanoparticle‐based strategy prevents bacterial translocation and liver damage without cardiorespiratory side effects, working through HDAC ...

Series solution of one-dimensional stationary thermal explosion problems

, 1976
A series solution is obtained for one-dimensional, stationary thermal explosion problems by expressing the temperature in the reactive material in terms of an even power series of the position variable.
