Internal Phase Separation in Synthetic DNA Condensates

Advanced Science, EarlyView.
The modular, programmable system of DNA nanostructures developed provides programmatic control over multiphase condensate behavior, enabling mapping onto a predictive Flory‐Huggins model. This combined experimental and theoretical framework will help address open questions in condensate biophysics and facilitate the rational design of functional ...

Preferential interaction coefficient for nucleic acids and other cylindrical poly-ions

, 2007
The thermodynamics of nucleic acid processes is heavily affected by the electric double-layer of micro-ions around the polyions. We focus here on the Coulombic contribution to the salt-polyelectrolyte preferential interaction (Donnan) coefficient and we ...

Clinically Inspired Multimodal Treatment Using Induced Neural Stem Cells‐Derived Exosomes Promotes Recovery of Traumatic Brain Injury through Microglial Modulation

Advanced Science, EarlyView.
This study explores the therapeutic potential of iNSC‐Exo via local and systemic delivery in TBI mice. It is found that iNSC‐Exo enhances NRXN signaling through Microglia_Nrg3 and Microglia_Rarb, effectively promoting functional and neurological recovery, suggesting a new therapeutic strategy for TBI. Abstract Traumatic brain injury (TBI) poses serious

Superhydrophilic FeIV2MnII Nanocluster: A Combined Diagnostic and Therapeutic Agent

Angewandte Chemie, EarlyView.
An atomically precise nanocluster with a superhydrophilic architecture acts as an efficient magnetic resonance imaging (MRI) and photoacoustic imaging (PAI) dual‐mode diagnostic agent, while providing for a photothermal‐based antitumor effect. Abstract We report here an atomically precise nanocluster, (NH4)2MnII(H2O)2[FeIV(L)]2·11H2O (Fe2Mn).

Graphitized Biochar Derived from Agricultural Wastes Enhances Methanogenesis via Conductivity‐Driven Direct Interspecies Electron Transfer

Advanced Science, EarlyView.
This work clarifies how feedstocks and their structural features promote methanogenesis, and identifies the key regulatory factors, reducing pollution to the global environment, and also helps to alleviate the energy crisis. This is the first study to systematically link feedstock lignin content, pyrolysis conditions, biochar graphitization, and DIET ...

Punicalagin Enhances Autophagy Through Sirtuin 1/FoxO3a Axis to Inhibit Intracellular Mycobacterium Abscessus Infection

Advanced Science, EarlyView.
Punicalagin, a pomegranate molecule, helps the body fight Mycobacterium abscessus. It preferentially boosts interstitial macrophages in the lung, stabilizing mitochondria and switching on the autophagy via SIRT1/FoxO3a, which lowers bacterial load without directly killing bacteria.

Design of nucleic acid sequences for DNA computing based on a thermodynamic approach

Nucleic Acids Research, 2005
We have developed an algorithm for designing multiple sequences of nucleic acids that have a uniform melting temperature between the sequence and its complement and that do not hybridize non-specifically with each other based on the minimum free energy (DeltaG (min)).

RNA G‐Quadruplex RIBOTAC‐Mediated Targeted Degradation of lncRNA TERRA

Advanced Science, EarlyView.
This study introduces a selective RNA degradation strategy targeting long noncoding RNA (lncRNA) TERRA, upregulated in ALT (alternative lengthening of telomeres) cancer cells. Using ribonuclease‐targeting chimeras (RIBOTACs), RNase L is recruited to catalytically degrade TERRA, uncovering a novel approach to affect a disease associated lncRNA in ALT ...
