Electrocatalytic Urea Synthesis From CO2 and N2/NO3−: Bridging Catalyst Activity, C–N Coupling Kinetics, and Industrial Applicability

Advanced Science, EarlyView.
This review compares NO3− + CO2 and N2 + CO2 electrocatalytic urea synthesis in feedstock properties, catalyst design, C–N coupling mechanisms, performance optimization, and engineering applicability. The two systems correspond to a near‐term deployable route and a long‐term green synthesis goal, respectively.

Combinatorial Tuning of Multigene Biosynthetic Pathways based on RNA Interference

Advanced Science, EarlyView.
Small RNA sequencing identifies candidate endogenous Pol III promoters, and subsequent fluorescence screening measures knockdown efficiency to assess promoter strength. Combining promoter strength and shRNA target position enables fine‐grained RNAi regulation of multigene pathways. This strategy enhances β‐carotene production in Schizochytrium sp.

Blood‐Based Biomarkers in Alzheimer's Disease: Advances in Detection Technologies and Clinical Applications

AGING MEDICINE, EarlyView.
Blood‐based biomarkers are emerging as accessible tools for Alzheimer's disease screening, diagnosis, risk stratification, and longitudinal monitoring. This review summarizes major biomarkers, including Aβ42/Aβ40, phosphorylated tau species, NfL, GFAP, genetic risk markers, and exploratory inflammatory, synaptic, and proteomic candidates.

Cerebral Hemodynamic Changes in Older Adults With Cognitive Complaints According to the Presence of Peripheral Artery Disease

AGING MEDICINE, EarlyView.
Among 132 older adults, 13 had peripheral artery disease (PAD), identified using the ankle–brachial index. Over approximately 13 months, PAD was associated with increasing middle cerebral artery mean flow velocity, with a significant difference in left‐sided velocity change between groups.
