ROS‐Driven Nanoventilator for MRSA‐Induced Acute Lung Injury Treatment via In Situ Oxygen Supply, Anti‐Inflammation and Immunomodulation

open access: yesAdvanced Science, EarlyView.
A ROS‐driven in situ oxygen supply nanoventilator based on enzyme nanocapsule can convert ROS into O2 through enzyme cascade reaction between SOD and CAT to relieve lung hypoxia, and kill MRSA by releasing vancomycin, which effectively reduces HIF‐1α expression and balances pro‐inflammatory/anti‐inflammatory macrophages ratio, thereby reducing the ...

Advancing the Identification of Bioactive Molecules and the Construction of a Synergistic Drug Delivery System in Combating Lung Injury

open access: yesAdvanced Science, EarlyView.
Traditional Chinese Medicine (TCM), while holistic and historically esteemed, faces challenges in “miracle cures” due to slow onset, long cycles, and difficulty controlling quality. This study obtains the active ingredients, glabridin (GLA) and puerarin (PUE), from Ge‐Gen Decoction (GGD), developing a safe and effective drug delivery system, GLA‐PUE ...

Quantitative Super‐Resolution Imaging of Molecular Tension

open access: yesAdvanced Science, EarlyView.
Quantitative tension PAINT (qtPAINT) is a new method to quantify molecular tension at super‐resolution by exploiting force‐dependent DNA oligonucleotide dissociation kinetics. Combining hairpin tension probes and molecular‐beacon imagers, qtPAINT achieves 9–30 pN continuous force quantification range with 30–120 nm spatial and minute‐scale temporal ...

FGF2 Mediated USP42‐PPARγ Axis Activation Ameliorates Liver Oxidative Damage and Promotes Regeneration

open access: yesAdvanced Science, EarlyView.
USP42 is identified as a novel DUB of PPARγ in hepatocytes. USP42 mediated PPARγ deubiquitylation determines its transcriptional preference on proliferative and redox balance genes. USP42 knockdown exacerbates liver damage and delays regeneration. FGF2 is the upstream signal that initiates and activates the USP42‐PPARγ axis.

Genome‐Wide Silencer Screening Reveals Key Silencer Modulating Reprogramming Efficiency in Mouse Induced Pluripotent Stem Cells

open access: yesAdvanced Science, EarlyView.
This study utilized Ss‐STARR‐seq to construct a genome‐wide silencer map of mouse cells and elucidated the fundamental characteristics of these silencers. These silencers exist in a cell‐specific manner and exhibit unique epigenetic modifications. Through functional experiments, we also discovered that these silencers can regulate gene expression and ...

Inhibition of Aberrant Activated Fibroblast‐Like Synoviocytes in Rheumatoid Arthritis by Leishmania Peptide via the Regulation of Fatty Acid Synthesis Metabolism

open access: yesAdvanced Science, EarlyView.
LACK156‐173 is internalized into RA‐FLSs via CAPN2‐mediated endocytosis and inhibits the aggressive phenotype of RA‐FLSs by restoring dysregulated fatty acid synthesis metabolism mediated by overexpressed FASN. The findings suggest that targeting the restoration of fatty acid metabolism could potentially alleviate synovial invasion and joint damage in ...

In‐Depth Cell‐Type‐Specific Proteome Landscape of the Brain from Human Amyloid‐β Overexpression Mouse Model

open access: yesAdvanced Science, EarlyView.
In situ Cell‐type‐specific proteome Analysis using antibody‐mediated Biotinylation (iCAB) is a method that directly targets and analyzes proteins in specific cell types within tissue. Applied to 5xFAD mice, iCAB identifies ≈8000 cell‐type‐specific proteins, revealing unique pathways in neurons, astrocytes, and microglia.

Antigen‐Targeting Inserted Nanomicelles Guide Pre‐Existing Immunity to Kill Head and Neck Cancer

open access: yesAdvanced Science, EarlyView.
This study introduces a tumor‐targeted nanomicelle platform (preS1‐pHLIP) that exploits pre‐existing antiviral immunity to combat heterogeneous cancers. By delivering viral antigens to label tumors as virus‐like targets, the nanomicelles activate antiviral B and T cells, triggering in situ tumor lysis.

On mechanisms of fluorescence quenching by water

Biophysics, 2014
Mechanisms of fluorescence quenching of aromatic chromophores by water are reviewed. The mechanisms include polarity of chromophore environment, proton or electron transfer between the excited chromophore and water. A hypothesis is proposed that the quenching can be a result of chromophore-solvent hydrogen bond breaking in the excited state.
