Don't Fall for Tuning Parameters: Tuning-Free Variable Selection in High Dimensions With the TREX

open access: yes, 2015
Lasso is a seminal contribution to high-dimensional statistics, but it hinges on a tuning parameter that is difficult to calibrate in practice. A partial remedy for this problem is Square-Root Lasso, because it inherently calibrates to the noise variance.

Dual‐Responsive Dynamic Covalent Bond‐Based Assembly of Lipid‐Nanozyme Systems via Multi‐Target Synergy and Efficient Target Enrichment for Ischemic Stroke Therapy

open access: yesAdvanced Science, EarlyView.
This system adopts a biomimetic phospholipid structure, covalently binding iNOS inhibitors, neuroprotective agent PCA and vitamin E derivatives through pH/ROS dual‐responsive bonds, and assembles them with Prussian blue nanozyme to form PBB@AHA. It can efficiently penetrate the blood‐brain barrier and simultaneously release multiple active components ...

Riboflavin synthase of Protein dynamics revealed by F NMR protein perturbation experiments [PDF]

open access: yes, 2003
Background Riboflavin synthase catalyzes the transformation of 6,7-dimethyl-8-ribityllumazine into riboflavin in the last step of the riboflavin biosynthetic pathway. Gram-negative bacteria and certain yeasts are unable to incorporate riboflavin from the

Plant‐Derived Melatonin Inhibits Bacterial Virulence via CpxA/R Two‐Component System

open access: yesAdvanced Science, EarlyView.
Plant‐derived melatonin is sensed by CpxAE48/T51, which inhibits the phosphorylation cascade transmission from CpxAH240 to CpxRD52, resulting in the inhibition of DNA‐binding capacity of CpxR and subsequent T3SS genes expression in Pst DC3000. ABSTRACT In defending against pathogens, plants deploy diverse secondary metabolites and signaling molecules ...

Effect of a mixture of caffeine and nicotinamide on the solubility of vitamin (B2) in aqueous solution [PDF]

open access: yes, 2006
The effect of caffeine (CAF) and nicotinamide (NMD) on the solubility of a vitamin B2 derivative (FMN) has been evaluated for mixtures containing either a single hydrotrope (CAF or NMD) or the two hydrotropes simultaneously.

Light‐Switched Mesenchymal Stem Cells for In Situ Exosome Amplification in Craniofacial Bone Defect Reconstruction

open access: yesAdvanced Science, EarlyView.
Light‐switchable MSCs (MSC‐UCNPs) were constructed by intracellular incorporation of UCNPs. Upon 980 nm irradiation, UCNPs emitted localized ultraviolet light (365 nm), activating the ROS/HEXB/LAMP1 signaling pathway to suppress lysosome–multivesicular body fusion and thereby enhance exosome biogenesis. Embedded within an injectable hydrogel, MSC‐UCNPs
