Advanced Science, EarlyView.Here we developed Am@SExo, a dual‐functional engineered exosome that coordinates CD47–SIRPα checkpoint blockade with Arg1 mRNA–mediated metabolic reprogramming. Surface SIRPα promotes recognition of apoptotic cells and plaque targeting, while Arg1 expression enhances arginine–ornithine metabolism, Rac1 activation, and actin remodeling in macrophages ...

Determining The Minimum Safe Flow Line For A 5 Stage, 350 Hp Variable Speed Centrifugal Pump [PDF]
, 2007 Case StudyCS1An energy survey revealed that two, a main and spare, 5 stage, 3560 rpm, 350 hp, centrifugal pumps were well oversized for their application. The pumps are used to inject waste water into several disposal wells. Due to the excess capacity of

Advanced Science, EarlyView.Host‐specific compatibility between RNF138‐like proteins and flavivirus NS5 determines NS5 stability. Mammalian RNF138 but not arthropod homologs recognizes and induces conserved NS5/RdRp K48‐linked ubiquitination and proteasomal degradation, thereby restricting viral replication. Ectopic RNF138 in mice attenuates TBEV‐induced pathogenesis. (Created in

L10: A FEM Approach to Predict Acoustic Resonance in Multistage Centrifugal Pump
, 2021 LecturesAcoustic resonance can develop within the hydraulic channels of the pump, especially in the long crossover channel of a multistagecentrifugal pump This phenomenon occurs when the hydraulic channel length is equal to the sound wavelength produced ...

Advanced Science, EarlyView.This study presents a surfaceome‐reprogramming strategy for mutation‐independent lung cancer therapy by repurposing dexamethasone to prime mesenchymal stem cell‐derived nanovesicles. The engineered vesicles leverage multi‐valent interactions mediated by upregulated adhesion proteins, EPHA2, and NOTCH3.
