Advanced Science, EarlyView.A new tissue sampling device using an acupuncture needle with bio‐compatible extraction sorbents in the recessed section is developed. The coating material using self‐wettable particles doesn't require solvent activation after sterilization. This device is applied for the anti‐cancer drug concentration monitoring during the in vivo lung perfusion ...

Advanced Science, EarlyView.Herbal medicine, with its multicomponent and multitarget potential, is often studied primarily for traditional forms, especially phytochemicals. Currently, ulcerative colitis lacks natural, low‐toxicity therapies, yet emerging research highlights plant‐derived exosomes as a promising option.

Molecular Chain Elongation Mechanism for n‐Caproate Biosynthesis by Megasphaera Hexanoica
Advanced Science, EarlyView.The medium‐chain carboxylate‐producing microbe Megasphaera hexanoica is analyzed through genomics, transcriptomics, and metabolic engineering. The n‐caproate biosynthetic pathway is reconstructed in Escherichia coli, highlighting MhTHL as a key β‐ketothiolase. Structural analysis and mutagenesis reveal that MhTHL has a distinct substrate‐binding pocket,

Advanced Science, EarlyView.Here, it is revealed that ovarian cancer cells release extracellular vesicles enriched with eIF4E, which alters protein production in macrophages. This leads to increased expression of 3‐hydroxy‐3‐methyl‐glutaryl‐coenzyme A reductase (HMGCR), boosting cholesterol synthesis and activating an immunosuppressive pathway through X‐box binding protein 1 and ...

Advanced Science, EarlyView.Ruminant meat is widely appreciated for its distinctive flavor. Lipids play a central role in influencing meat flavor, yet their genetic and biochemical basis remains largely unexplored. Here, a comprehensive lipid genetic map of sheep muscle is constructed and 20 candidate genes potentially modulating lipid levels are identified to provide a roadmap ...
