Insights into the Dynamics and Binding Mechanisms of the Alkhumra Virus NS2B/NS3 Protease: A Molecular Dynamics Study

Advanced Theory and Simulations, EarlyView.
The ΔRMSF$\Delta {\rm RMSF}$ analysis reveals significant flexibility differences between free NS3 and the NS2B/NS3 complex, with notable deviations in specific regions. Key residues driving NS2B binding are identified, and the protonation state of catalytic serine affects oxyanion hole formation.

Sustained Vaccine Exposure Elicits More Rapid, Consistent, and Broad Humoral Immune Responses to Multivalent Influenza Vaccines

Advanced Science, EarlyView.
This work presents an injectable polymer‐nanoparticle hydrogel depot platform for delivering multivalent influenza vaccines which induces stronger and more durable immune responses. The technology provides broader protection, including against heterologous and potential pandemic strains (H5N1, H7N9, H9N2), and enhances the effectiveness of commercial ...

FUS Selectively Facilitates circRNAs Packing into Small Extracellular Vesicles within Hypoxia Neuron

Advanced Science, EarlyView.
This study aimed to unravel the role of FUS in the loading of functional circRNAs into neuronal sEVs under hypoxic conditions, which involves their aggregations in SGs and specific interaction between the FUS Zf_RanBP domain to regulate circRNA sorting in sEVs.

The Placenta Regulates Intrauterine Fetal Growth via Exosomal PPARγ

Advanced Science, EarlyView.
The placenta expresses much higher levels of PPARγ than fetal adipose tissue. Trophoblastic exosomes transport PPARγ into fetal preadipocytes via fetoplacental circulation and thus regulate adipogenic genes distinct from endogenous PPARγ. Compromised placental PPARγ leads to fetal adipogenesis deficiency and intrauterine growth restriction, reversible ...

Curcumin Modulates PTPRZ1 Activity and RNA m6A Modifications in Neuroinflammation‐Associated Microglial Response

Advanced Science, EarlyView.
Wenxiang Meng and colleagues delve into the molecular mechanisms underlying curcumin's modulation of RNA post‐transcriptional N (6)‐methyladenosine (m6A) modification. It is found that curcumin interacts with the Z1‐type protein tyrosine phosphatase receptor (PTPRZ1), maintaining its enzymatic activity and thus regulating the phosphorylation of the m6A‐

ROS‐Driven Nanoventilator for MRSA‐Induced Acute Lung Injury Treatment via In Situ Oxygen Supply, Anti‐Inflammation and Immunomodulation

Advanced Science, EarlyView.
A ROS‐driven in situ oxygen supply nanoventilator based on enzyme nanocapsule can convert ROS into O2 through enzyme cascade reaction between SOD and CAT to relieve lung hypoxia, and kill MRSA by releasing vancomycin, which effectively reduces HIF‐1α expression and balances pro‐inflammatory/anti‐inflammatory macrophages ratio, thereby reducing the ...

High efficiency quantification of $^{90}$Sr contamination in cow milk after a nuclear accident [PDF]

arXiv
Monitoring $^{90}$Sr contamination in milk following a nuclear accident is critical due to its radiotoxicity and calcium-mimicking behaviour, leading to accumulation in bones and teeth. This study presents a high-efficiency protocol for quantifying$^{90}$Sr in cow milk by integrating freeze-drying, high-temperature calcination, ion exchange ...

Viral‐Mediated Connexin 26 Expression Combined with Dexamethasone Rescues Hearing in a Conditional Gjb2 Null Mice Model

Advanced Science, EarlyView.
AAV2.7m8 serotype combined with the gfaABC1D promoter targets infection of supporting cells (SCs). AAV2.7m8‐gfaABC1D‐Gjb2 administration to mice results in excessive immune responses. The combination of AAV2.7m8‐gfaABC1D‐Gjb2 with dexamethasone (DEX) shows a synergistic effect and enhances the gene therapy effect in a conditional Cx26 null mice model ...
