Intranasal Immunization With Nanoparticles Containing an Protein Vaccine Candidate and a Polysorbitol Transporter Adjuvant Enhances Both Humoral and Cellular Immune Responses.

Scrub typhus, a mite-borne infectious disease, is caused by . Despite many attempts to develop a protective strategy, an effective preventive vaccine has not been developed. The identification of appropriate Ags that cover diverse antigenic strains and provide long-lasting immunity is a fundamental challenge in the development of a scrub typhus vaccine.

Remodeling and Restraining Lung Tissue Damage Through the Regulation of Respiratory Immune Responses.

Tissue damage caused by various stimuli under certain conditions, such as biological and environmental cues, can actively induce systemic and/or local immune responses. Therefore, understanding the immunological perspective would be critical to not only regulating homeostasis of organs and tissues but also to restrict and remodel their damage. Lungs serve as one of the key immunological organs, and thus, in the present article, we focus on the innate and adaptive immune systems involved in remodeling and engineering lung tissue.

Redox and catalytic properties of biochar-coated zero-valent iron for the removal of nitro explosives and halogenated phenols.

A novel biochar-coated zero-valent iron [Fe(0)], which was synthesized with rice straw and Fe(0), was applied to remove nitro explosives (2,4,6-trinitrotoluene and hexahydro-1,3,5-trinitro-1,3,5-triazine) and halogenated phenols (2,4-dibromophenol and 2,4-difluorophenol) from contaminated waters. Due to the presence of biochar on the outside, the removal of nitro explosives and halogenated phenols was significantly enhanced via sorption. The sorbed contaminants were further transformed into reductive products, indicating that the inner Fe(0) played the role of a reductant in the biochar-coated Fe(0).

The application of catalyst-recovered SnO2 as an anode material for lithium secondary batteries.

We studied the electrochemical characteristics of tin dioxide (SnO2) recovered from waste catalyst material which had been previously used in a polymer synthesis reaction. In order to improve the electrochemical performance of the SnO2 anode electrode, we synthesized a nanocomposite of recovered SnO2 and commercial iron oxide (Fe2O3) (weight ratio 95:5) using a solid state method. X-ray diffraction (XRD) and field emission scanning electron microscopy (FE-SEM) analyses revealed an additional iron oxide phase within a porous nanocomposite architecture.

The α-iso-cubebenol compound isolated from Schisandra chinensis induces p53-independent pathway-mediated apoptosis in hepatocellular carcinoma cells.

Schisandra chinensis (S. chinensis) plants are extensively used because of their anticancer, anti-inflammatory, antioxidant and antihepatic activities. However, their active compounds remain to be clearly determined.

A neutral lipase applicable in biodiesel production from a newly isolated Streptomyces sp. CS326.

In an attempt to isolate a biocatalyst able to catalyze biodiesel production from microbial source, Streptomyces sp. CS326 was screened from hundreds of soil isolates collected from various parts of Korea. In 16S rRNA sequence analysis, the strain showed high degree of similarity with Streptomyces xanthocidicus (99.

A newly isolated Streptomyces sp. CS392 producing three antimicrobial compounds.

With the aim of isolating new microbes capable of producing strong antimicrobial substances, strain CS392 was screened from 700 soil isolates preserved in our laboratory. The strain was related to genus Streptomyces based on various characteristics. Three highly active antimicrobial compounds, C1, C2 and C3, produced by the strain were purified by solvent extraction followed by silica gel column chromatography.
