Optimization of CEST MRI Reporter Protein Design Using Cation‐Pi Networks
Chemistry – A European Journal, EarlyView.A novel engineering approach can produce reporter proteins for cell and viral therapy tracking with unique magnetic resonance imaging (MRI) signatures, detectable with chemical exchange saturation transfer (CEST). We discover how cation‐π interactions between amino acid groups can help us fine‐tune magnetic resonance properties for noninvasive ...

Bottom‐up Strategies for Generating Polymer Protocells That Mimic Cellular Communication
Chemistry – A European Journal, EarlyView.This review focuses on polymeric protocells produced using a bottom‐up approach. Polymer‐based assemblies guarantee stability and designability by adjusting the properties of the amphiphilic copolymers used. The review covers protocell architectures, production, and their intra‐ and intercellular communication mechanisms.

Overview of PLL methods for distributed generation units [PDF]
, 2010 Distributed energy resources are increasingly being connected to the utility grid by means of an inverter. The basic information necessary for these inverter-connected distribution units are the frequency and phase angle of the utility grid.

Protocol for Reconstituting Adaptor‐Mediated Activation of Full‐Length Kinesin‐1
Cytoskeleton, EarlyView.ABSTRACT Kinesin‐1 is a member of the kinesin superfamily that plays an essential role in intracellular cargo transport. In the absence of cargo, Kinesin‐1 exhibits low motor activity due to autoinhibition. Multiple studies have demonstrated that adaptor proteins, which link cargos to Kinesin‐1, can activate Kinesin‐1 by releasing the autoinhibition ...

Investigating the Cytoskeleton of DRGs Using Cryo‐Electron Microscopy and Deep Learning
Cytoskeleton, EarlyView.ABSTRACT We describe a method for determining the ultrastructural organization of axons and varicosities of cultured dorsal root ganglion (DRG) neurons using cryogenic electron microscopy (cryo‐EM). Cryo‐EM reveals the dimensions, proximity, and overall organization of biological specimens in a near‐native state, avoiding artifacts of fixation and ...
