Radiation‐Triggered Chemokine‐Secreting Probiotics for Boron Neutron Capture Therapy Based Radioimmunotherapy

Advanced Science, EarlyView.
Engineered Escherichia coli Nissle 1917 with a tannic acid‐mediated BPA coating enables tumor‐targeted boron delivery for BNCT. The low‐level incidental radiation generated during BNCT activate a RecA‐driven circuit to induce CXCL10, while radiation‐enhanced bacterial colonization triggers in situ vaccination and systemic antitumor immunity.

Ice core drilling on the southern slope of the Nepal Himalayas [PDF]

, 2002
P(論文)Two ice cores were extracted from Rikha Samba Glacier located in the central Nepal Himalayas in 1994 and 1998. Ice core quality in 1994 was poor due to cutter problems and samples were melted in situ.

Nrsn1–Smarcc1 Coupling Regulates Neural Stem Cell Differentiation and Chronic‐phase Recovery After Ischemic Stroke

Advanced Science, EarlyView.
In the post‐stroke brain, Foxa2 induces the transcriptional upregulation of Nrsn1 in NSCs. Nrsn1 functionally couples with Smarcc1, modulating its nuclear availability and protein abundance, thereby influencing Smarcc1‐associated regulatory programs linked to neuronal lineage commitment. Through this coupling, Nrsn1 promotes the differentiation of NSCs

Bone Marrow Macrophage STING Signaling is a Direct Nexus Linking Marrow Adipose Expansion to NAD+ Depletion and Osteogenic Decline in Skeletal Aging

Advanced Science, EarlyView.
This study reveals that during skeletal aging, bone marrow adipocyte‐derived sDPP4 primes STING signaling in macrophages. In combination with mitochondrial DNA, this signaling activates CD38 and depletes local NAD+/NMN, thereby impairing osteogenesis.

Dome Argus: Ideal site for deep ice drilling [PDF]

, 2012
Located on the centre of ice drainage range, the highest Dome Argus (Dome A) of East Antarctic Ice Sheet (EAIS), could be represented as an ideal site for deep ice cores drilling containing oldest paleo-climate records. To select a suitable drilling site

Mechanically Robust, Self‐Healable, and Cryotolerant GelMA Hydrogel for Wearable Tactile Sensors with Enhanced Durability, Lifetime, and Environmental Stability

Advanced Science, EarlyView.
A mechanically robust, self‐healable, moisturizing, cryotolerant and adhesive GelMA hydrogel is developed by incorporating polyvinyl alcohol, acrylic acid, sodium tetraborate, and glycerol into GelMA matrix via a photoinitiated polymerization process. The hydrogel‐derived omni‐healable ionotronic pressure sensor can sensitively and consistently monitor

SIRT7‐Mediated H2BK120 Succinylation Drives Aberrant Mitophagy in Sepsis‐Associated Cognitive Dysfunction

Advanced Science, EarlyView.
Sepsis triggers hippocampal SIRT7 loss, promoting histone H2B succinylation and activation of the PD‐1/PD‐L1–PINK1 axis. This metabolic‐epigenetic cascade drives aberrant mitophagy and neuronal injury, ultimately causing cognitive deficits. Targeting SIRT7‐dependent succinylation offers a potential strategy to protect brain function during sepsis ...
