Efficient Neutralizing Antibodies Induction by Human Parvovirus B19 Epitope-Presenting Protein Nanoparticles.

Human parvovirus B19 (B19V) causes fetal hydrops in pregnant women. Despite the significant impact of this virus, effective vaccines remain unclear. In this study, we successfully engineered B19V protein nanoparticles by fusing the N-terminal receptor-binding domain corresponding to 5-80 amino acids of VP1 with two distinct types of self-assembling protein nanoparticles.

Electrospray mass spectrometry method to prevent the reduction of hexavalent to pentavalent chromium.

Rationale: Electrospray mass spectrometry (ESI-MS) is one of the most effective methods for assessing the state of metals in solution. For ions with a redox potential close to ~0.55 V, such as Cr , reduction of the metal in solution occurs in the ESI-MS system.

Preparation of gold nanoparticles using low-temperature heating of the dry residue of a droplet of an HAuCl solution in air.

In the present study, by heating a quartz glass substrate having the dry residue of a 10 μL droplet of a solution of HAuCl and a counter substrate facing to the dry residue from room temperature to one hundred and several tens of degrees Celsius in 20 min in air, highly dense gold nanoparticles were produced on the counter substrate. A gold nanoparticle substrate produced by this simple method was utilized as a substrate for surface-enhanced Raman scattering analysis.

Complete Genome Sequence of Bifidobacterium longum Strain Jih1, Isolated from Human Feces.

We report the complete genome sequence of strain Jih1, isolated from human feces. The assembled genome comprised one circular chromosome of 2.37 Mb.

XitoSBML: A Modeling Tool for Creating Spatial Systems Biology Markup Language Models From Microscopic Images.

XitoSBML is a software tool designed to create an SBML (Systems Biology Markup Language) Level 3 Version 1 document from microscopic cellular images. It is implemented as an ImageJ plug-in and is designed to create spatial models that reflect the three-dimensional cellular geometry. With XitoSBML, users can perform spatial model simulations based on realistic cellular geometry by using SBML-supported software tools, including simulators such as Virtual Cell and Spatial Simulator.
