Spatial Coordination Structure‐Driven Enzyme‐Like Selectivity in Single‐Atom Nanozymes

open access: yesAdvanced Materials, EarlyView.
Sun et al. reviews recent progress in enhancing the enzyme‐like catalytic selectivity of SAzymes through the rational design of their spatial coordination structures. They emphasize the structure‐activity relationships of various attributes of these coordination structures in promoting selective catalytic behavior, the strategic design of coordination ...

c-Type Cytochrome Assembly Is a Key Target of Copper Toxicity within the Bacterial Periplasm

open access: yesmBio, 2015
In the absence of a tight control of copper entrance into cells, bacteria have evolved different systems to control copper concentration within the cytoplasm and the periplasm.

Automated Transcranial Photobiomodulation in Healthy Rats: Effects on Working Memory and Brain Markers

open access: yesAdvanced Therapeutics, EarlyView.
Transcranial photobiomodulation (PBM) enhances spatial working memory in healthy rats under both continuous and alternating stimulation protocols. At the neural level, PBM modulates cytochrome c oxidase activity, increases prefrontal and hippocampal synaptic markers, and induces region‐specific c‐Fos expression. These effects suggest improved cognitive

Understanding miR‐200c: an Important Player in Resistance to Cancer Treatment

open access: yesAdvanced Therapeutics, EarlyView.
How can one microRNA alter cancer's response to therapy? miR‐200c plays a central role in therapeutic resistance by modulating epithelial‐mesenchymal transition, apoptosis, cancer stemness features, and drug efflux. This review outlines the context‐dependent functions of miR‐200c in various cancers and highlights its potential as both a biomarker and a

Engineering Electron Transfer Flux between Cytochrome P450 Enzyme and P450 Reductase to Enhance Serotonin Production in Escherichia Coli

open access: yesAdvanced Science, EarlyView.
The electron transfer flux in CPR‐P450 catalytic system is systematically engineered through: i) enhancing electron transfer rate by redesigning the putative electron transfer pathway of CPR; ii) improving electron‐receiving rate by evolving the heme domain of tryptophan‐5‐hydroxylase (T5H); iii) enlarging electron supply by fine‐tuning NADPH synthesis.

Semi-Supervised Sparse Coding

open access: yes, 2015
Sparse coding approximates the data sample as a sparse linear combination of some basic codewords and uses the sparse codes as new presentations. In this paper, we investigate learning discriminative sparse codes by sparse coding in a semi-supervised ...

Gentle Label‐Free Nonlinear Optical Imaging Relaxes Linear‐Absorption‐Mediated Triplet

open access: yesAdvanced Science, EarlyView.
The phototoxicity in nonlinear optical microscopy arises mainly from linear absorption of intrinsic biomolecules rather than nonlinear absorption. This mechanism is supported by a reproducible phototoxicity assay based on widely available chicken breast.
