Background: Engineering nanotherapeutics have been extensively studied for cancer therapy. However, the therapeutic efficacy is still severely restricted by biophysiological barriers and intracellular accumulation. Although the biomimetic nanoparticles have improved the former issue, there is almost no breakthrough in researches of intracellular transport. Herein, we proposed a NIR-responsive nuclear-targeted hybrid membrane biomimetic Prussian blue drug-loading nanotherapeutics (PB@DN@M). Results: The hybrid membrane coating bestows nanotherapeutics tumor targeting and immune escape ability, thus promoting the tumor enrichment of PB nanotherapeutics. The nuclear targeting function triggered by NIR enhances the cellular internalization and nuclear entry efficiency, resulting in a superadditive effect for boosting photothermal-chemotherapy efficacy. Moreover, taking advantage of non-interference Raman properties of PB, we can track the location and distribution of nanotherapeutics, which is beneficial for guiding precise synchronization of photothermal-chemotherapy. The results revealed that this PB@DN@M presented a remarkable therapeutic efficacy and significantly inhibited the tumor growth up to 87.17%. Conclusions: Therefore, this spatiotemporal controllable biomimetic nanotherapeutics will provide a new insight and strategy for specific targeted therapy of tumors. [ABSTRACT FROM AUTHOR]

Unified airway disease, including concurrent asthma and chronic rhinosinusitis (CRS), is a common, but poorly understood disorder with no curative treatment options. To establish a murine model of chronic unified eosinophilic airway inflammation, mice were challenged with Aspergillus niger , and sinonasal mucosa and lung tissue were evaluated by immunohistochemistry, flow cytometry, and gene expression. Inhalation of A niger conidia resulted in a Th2-biased lung and sinus inflammation that typifies allergic asthma and CRS. Gene network and pathway analysis correlated with human disease with upregulation of not only the JAK-STAT and helper T-cell pathways, but also less expected pathways governing the spliceosome, osteoclast differentiation, and coagulation pathways. Utilizing a specific inhibitor and gene-deficient mice, we demonstrate that STAT6 is required for mycosis-induced sinus inflammation. These findings confirm the relevance of this new model and portend future studies that further extend our understanding of the immunopathologic basis of airway mycosis and unified airway disease.

Mosses compose one of the three lineages of bryophytes. Today, about 13,000 species of mosses are recognized from across the globe, and at least one-third of this diversity composes the Hypnales, a lineage characterized by an early rapid radiation. We sequenced and de novo assembled the genomes of two hypnalean mosses, namely Entodon seductrix and Hypnum curvifolium , based on the 10x genomics and Hi-C data. The genome assemblies of E. seductrix and H. curvifolium comprise 348.4 and 262.0 Mb, respectively, estimated by k -mer analyses to represent 93.3% and 97.2% of their total genome size. Both genomes were assembled at the chromosome level, with scaffold N50 of 30.0 and 20.7 Mb, respectively. The annotated genome of E. seductrix comprises 25,801 protein-coding genes and that of H. curvifolium 29,077, estimated to represent 96.8% and 97.2%, respectively, of the total gene spaces based on BUSCO (Benchmarking Universal Single-Copy Ortholog) assessment. For both genomes, most contigs were anchored to the largest 11 pseudomolecules, corresponding to the 11 chromosomes of the two species, and each with a putative sex-related chromosome characterized by low gene density. The chromosomes of E. seductrix and H. curvifolium are highly syntenic, suggests limited architectural shifts occurred following the rapid radiation of the Hypnales. We compared their genomic features to the model moss Physcomitrium patens. The hypnalean moss genomes lack signatures of recent whole-genome duplication. The presented high-quality moss genomes provide new resources for comparative genomics to potentially unveil the genomic evolution of derived moss lineages. [ABSTRACT FROM AUTHOR]

Background: Inhalation of fungal spores is a strong risk factor for severe asthma and experimentally leads to development of airway mycosis and asthma-like disease in mice. However, in addition to fungal spores, humans are simultaneously exposed to other inflammatory agents such as lipopolysaccharide (LPS), with uncertain relevance to disease expression. To determine how high dose inhalation of LPS influences the expression of allergic airway disease induced by the allergenic mold Aspergillus niger (A. niger).Methods: C57BL/6J mice were intranasally challenged with the viable spores of A. niger with and without 1 μg of LPS over two weeks. Changes in airway hyperreactivity, airway and lung inflammatory cell recruitment, antigen-specific immunoglobulins, and histopathology were determined.Results: In comparison to mice challenged only with A. niger, addition of LPS (1 μg) to A. niger abrogated airway hyperresponsiveness and strongly attenuated airway eosinophilia, PAS+ goblet cells and TH2 responses while enhancing TH1 and TH17 cell recruitment to lung. Addition of LPS resulted in more severe, diffuse lung inflammation with scattered, loosely-formed parenchymal granulomas, but failed to alter fungus-induced IgE and IgG antibodies.Conclusions: In contrast to the strongly allergic lung phenotype induced by fungal spores alone, addition of a relatively high dose of LPS abrogates asthma-like features, replacing them with a phenotype more consistent with acute hypersensitivity pneumonitis (HP). These findings extend the already established link between airway mycosis and asthma to HP and describe a robust model for further dissecting the pathophysiology of HP.

The efficiency of fully homomorphic encryption has always affected its practicality. With the dawn of Internet of things, the demand for computation and encryption on resource-constrained devices is increasing. Complex cryptographic computing is a major burden for those devices, while outsourcing can provide great convenience for them. In this paper, we firstly propose a generic blockchain-based framework for secure computation outsourcing and then propose an algorithm for secure outsourcing of polynomial multiplication into the blockchain. Our algorithm for polynomial multiplication can reduce the local computation cost to O n . Previous work based on Fast Fourier Transform can only achieve O n log n for the local cost. Finally, we integrate the two secure outsourcing schemes for polynomial multiplication and modular exponentiation into the fully homomorphic encryption using hidden ideal lattice and get an outsourcing scheme of fully homomorphic encryption. Through security analysis, our schemes achieve the goals of privacy protection against passive attackers and cheating detection against active attackers. Experiments also demonstrate our schemes are more efficient in comparisons with the corresponding nonoutsourcing schemes. [ABSTRACT FROM AUTHOR]
