Understanding and Regulating C–N Coupling Pathways for Electrocatalytic Urea Synthesis From CO2 and NO3−/NO2−

open access: yesAdvanced Science, EarlyView.
Understanding and regulating C–N coupling is central to electrocatalytic urea synthesis from CO2 and NO3−/NO2−. This review outlines representative coupling pathways, summarizes carbon‐ and nitrogen‐side intermediate regulation strategies, and highlights in situ/operando tools for mechanistic clarification and catalyst design. ABSTRACT Electrocatalytic

DLST Succinylation‐Mediated Mitochondrial Metabolic Remodeling and Cuproptosis Resistance Promote Malignant Progression of Lung Adenocarcinoma

open access: yesAdvanced Science, EarlyView.
The DLST K409 succinylation mediated by CPT1A promotes OXPHOS and redox homeostasis through regulating enzyme activity, thereby promoting the malignant progression of LUAD. Notably, the succinylation of DLST can enhance the cuproptosis resistance by inhibiting its lipoylation.

TRACING ENERGY FLOW PATHWAYS TO FISH USING FATTY ACIDS AND STABLE ISOTOPES OF HYDROGEN AND OXYGEN

open access: yes, 2012
Recent studies have demonstrated that use of stable carbon isotopes and fatty acid biomarkers in combination can be a powerful approach to elucidate trophic relationships in aquatic ecosystems.

Gut Microbiota‐Derived Indole‐3‐Propionic Acid Alleviates Diabetic Osteoporosis Through Nrf2‐Mediated Ferroptosis Suppression

open access: yesAdvanced Science, EarlyView.
Diabetes‐associated dysbiosis is accompanied by reduced Clostridium abundance, impaired microbial tryptophan metabolism, and lower circulating indole‐3‐propionic acid (IPA). Exogenous IPA improves trabecular microarchitecture and bone formation and restores Nrf2‐associated antioxidant signaling in bone marrow mesenchymal stem cells, limiting iron ...

Triple Oxygen and Hydrogen Isotopes of Soil Water Across Climates, Seasons, and Depths

open access: yesGeochemistry, Geophysics, Geosystems
Soil waters are a central component of the terrestrial water cycle. Their δ2H, δ18O, and d‐excess values contain rich information about hydroclimate, including the source of moisture and its evaporative history.

Advances in Aptamer Drug Delivery Systems for Treatment of Glioblastoma

open access: yesAdvanced Science, EarlyView.
Aptamers have remarkable recognition capacity which is suitable for assisting drug delivery for GB. This review demonstrates that aptamers have great potential as targeted therapeutic carriers, conjugated to various therapeutic carriers, using a range of conjugation strategies and chemistries.

Cycad forensics: tracing the origin of poached cycads using stable isotapes, trace element concentrations and radiocarbon dating techniques [PDF]

open access: yes, 2013
In South Africa, the greatest threat to cycad populations is the illegal removal of wild plants for landscaping purposes and collector's gardens, resulting in declining populations that are already threatened with extinction.

Linker‐Locking Strategy for the Rigidification of Flexible Metal–Organic Framework: Structural Stabilization and Controlled ESIPT for H2O/D2O Sensing

open access: yesAdvanced Science, EarlyView.
A linker‐locking strategy rigidifies the flexible metal–organic framework (MOF) MIL‐53‐(OH)2 via the cooperative encapsulation of ligands and structural water. This network significantly enhances the framework's aqueous stability. Crucially, rigidification suppresses enol emission to yield a single keto tautomer state with an extended lifetime ...

High‐Density Type I Collagen Promotes IFN‐γ+ CD8+ T Cell Exhaustion via SAT1‐ASS1‐Mediated Glutamine Accumulation and Ferroptosis in Triple‐Negative Breast Cancer

open access: yesAdvanced Science, EarlyView.
High‐density type I collagen promotes glutamine (Gln) accumulation–related ferroptosis of TNBC cells via the spermidine/spermine N1‐acetyltransferase 1 (SAT1)‐ argininosuccinate synthase (ASS1) signaling pathway, thus depriving immune cells of Gln supply and inducing IFN‐γ+ CD8+ T cell exhaustion in the TME.
