Photo‐Empowered Macrophage‐Based Drug Delivery System Overcomes Motility Suppression and Significantly Enhances Deep Tumor Drug Delivery

open access: yesAdvanced Science, EarlyView.
This study develops a photo‐empowered macrophage‐based (PEM) drug delivery system that provides a novel and effective solution for restoring cellular motility to enhance drug delivery and overcome hypoxia‐induced multidrug resistance. The construction of the PEM system fully exploits the unique biological properties of macrophages and the energy ...

Medicago Sativa L. Saponin‐Driven Lactobacillus Intestinalis Restores Intestinal Stemness in Naturally Aged Mice via the Bile Acid‐FXR‐Wnt Signaling Axis

open access: yesAdvanced Science, EarlyView.
This study examines the mechanism by which alfalfa saponin (AS) regulates intestinal stemness via modulation of the gut microbiota. The results indicate that AS significantly increases the abundance of Lactobacillus intestinalis, which subsequently activates Wnt signaling via bile acid metabolism and enhances intestinal stemness. These findings provide

Photocatalytically Activated Cu‐N1S3 Single‐Atom Nanozyme: Enhancing Enzyme Activities and Antibacterial Synergy for Highly Efficient Fruit Preservation

open access: yesAdvanced Science, EarlyView.
This study presents S‐coordinated Cu single‐atom nanozymes (Cu/CNS) fabricated via mild photocatalytic self‐assembly strategy. The nanozyme exhibits exceptional multi‐enzyme activity and near‐perfect antimicrobial efficacy. Incorporated into chitosan‐gelatin film, it enables pH‐responsive, broad‐spectrum fruit preservation, more than doubling the shelf‐

Abnormal response of left ventricular systolic function to submaximal exercise in post-partial left ventriculotomy patients

open access: yesBrazilian Journal of Medical and Biological Research, 2007
Patients with heart failure who have undergone partial left ventriculotomy improve resting left ventricular systolic function, but have limited functional capacity. We studied systolic and diastolic left ventricular function at rest and during submaximal

Lactobacillus Salivarius‐Derived Indole‐3‐Acetic Acid Promotes AHR‐PARP1 Axis‐Mediated DNA Repair to Mitigate Intestinal Aging

open access: yesAdvanced Science, EarlyView.
Indole‐3‐acetic acid (IAA) acting as one of the aryl hydrocarbon receptor (AHR) endogenous ligands is identified to be derived from Lactobacillus salivarius via its catalytic enzyme (ALDH) rather than host cells. Lactobacillus salivarius and IAA supplementation effectively mitigate intestinal aging by facilitating AHR‐poly (ADP‐ribose) polymerase 1 ...
