Scalable Fabrication of Freestanding Jammed Nanoparticle Films via Pickering Emulsion-Mediated Interfacial Assembly.

Freestanding networked nanoparticle (NP) films hold substantial potential due to their high surface areas and customizable porosities. However, NPs with high surface energies and heterogeneous sizes or shapes present considerable challenges as they tend to aggregate, compromising their structural integrities. In this study, we report the scalable fabrication of ultrathin, bicontinuous, and densely packed carbon NP films via Pickering emulsion-mediated interfacial assembly.

Protection against tuberculosis by vaccination of secreted chorismate mutase (Rv1885c) combined with a hepatitis B virus (HBV)-derived peptide, Poly6, and alum adjuvants.

Tuberculosis (TB) remains a significant global health issue due to the limited efficacy of the Bacillus Calmette-Guérin (BCG) vaccine, highlighting the need for the development of an improved TB vaccine. In this study, we created a novel TB subunit vaccine consisting of TB-secreted chorismate mutase (TBCM) (Rv1885c) and a hepatitis B virus (HBV)-derived peptide (Poly6), which elicits Type I interferon responses, both with and without an alum adjuvant. We evaluated the immunogenicity, protective efficacy, and therapeutic efficacy of this vaccine candidate in an in vivo mouse model.

Biodistribution is crucial for EVs intended for therapeutic purposes because it can determine the degree of on- and off-target effects. This study aimed to explore techniques to evaluate the biodistribution of unmodified EVs.

Association of Serum Metabolites with Serum Indices and Preanalytical Factors of Biobanked Serum Samples.

Serum indices (hemolysis, icterus, and lipemia; HIL) are known to impact clinical chemistry assay results. This study aimed to investigate the impact of HIL indices on serum metabolite profiles and the association of serum metabolite levels with pre-analytical factors of serum samples. A cohort of serum samples ( = 12,196) from the Korean Genome and Epidemiology Study (KoGES) was analyzed for HIL indices and the pre-analytical variables (SPRECs) which were generated in the process of serum collection.

Stochastic characterization of navigation strategies in an automated variant of the Barnes maze.

Animals can use a repertoire of strategies to navigate in an environment, and it remains an intriguing question how these strategies are selected based on the nature and familiarity of environments. To investigate this question, we developed a fully automated variant of the Barnes maze, characterized by 24 vestibules distributed along the periphery of a circular arena, and monitored the trajectories of mice over 15 days as they learned to navigate towards a goal vestibule from a random start vestibule. We show that the patterns of vestibule visits can be reproduced by the combination of three stochastic processes reminiscent of random, serial, and spatial strategies.

A phosphorylation code coordinating transcription condensate dynamics with DNA replication.

Chromatin is organized into compartments enriched with functionally-related proteins driving non-linear biochemical activities. Some compartments, transcription foci, behave as liquid condensates. While the principles governing the enrichment of proteins within condensates are being elucidated, mechanisms that coordinate condensate dynamics with other nuclear processes like DNA replication have not been identified.

Disrupted Rotational Perception During Simultaneous Stimulation of Rotation and Inertia.

Two vestibular signals, rotational and inertial cues, converge for the perception of complex motion. However, how vestibular perception is built on neuronal behaviors and decision-making processes, especially during the simultaneous presentation of rotational and inertial cues, has yet to be elucidated in humans. In this study, we analyzed the perceptual responses of 20 participants after pairwise rotational experiments, comprised of four control and four test sessions.
