A biosensor, including a modified gold electrode and a macrophage RAW264.7 immobilized on the modified gold electrode. The disclosure also provides a method of preparing the biosensor and a method of using the same for evaluation of antioxidant capacity of substances.

Disclosed herein is are methods and apparatuses for synthesizing deposited films of compounds (e.g., organic compounds such as a pharmaceutical active ingredient or a new chemical entity) on or in a variety of substrates, where such deposited compounds the desired stability under storage conditions, ease of handling, and yet enhanced dissolution properties when used in various assays. The disclosure further relates to methods of coating substrates, such as medical or diagnostic devices, with deposited films of organic compounds, as well as film-coated substrates.

The invention relates to selection of bacterial strain for use in treating serotonin deficiency and/or a disease related to serotonin deficiency by culturing bacteria of a lactic acid producing bacterial strain, under aerobic conditions, in a culture medium comprising tryptophan. Any serotonin produced by the bacteria of the lactic acid producing bacterial strain in the culture medium is detected and the lactic acid producing bacterial strain is selected as effective in treating serotonin deficiency and/or a disease related to serotonin deficiency in a subject if serotonin is detected in the culture medium.

Provided are a humanized transgenic non-human animal, especially a rodent, in particular a transgenic mouse containing a human interleukin 17A (IL-17A) gene, a human gene 17RA (IL-17RA) and/or a human TNF-alpha gene, and a preparation method therefor and the use thereof.

A method of assessing a possibility of cancerization including culturing a cell structure including normal cells and having a vascular network structure in a presence of a biological specimen from a subject, and assessing a possibility of cancerization in the subject based on a state of vessels in the cell structure after the culturing. The biological specimen is a body fluid specimen from the subject, a cell extract of cells from the subject, or a culture supernatant of cells from the subject, and the possibility of cancerization is assessed as high in the subject when a number of cells forming the vessels in the cell structure is larger than a number of cells cultured in an absence of the body fluid specimen, or when the vascular network structure in the cell structure extends.

A method of analysis using mass spectrometry and/or ion mobility spectrometry is disclosed. The method comprises: using a first device to generate smoke, aerosol or vapour from a target comprising or consisting of a microbial population; mass analysing and/or ion mobility analysing said smoke, aerosol or vapour, or ions derived therefrom, in order to obtain spectrometric data; and analysing said spectrometric data in order to analyse said microbial population.

An image generation device includes: a detection unit 43 that performs processing of detecting a specific feature from a plurality of focus images which include an observation target and are in different focus states; a determination unit 44 that determines a parameter indicating a degree of application of a region image to a combination region image in a case where the combination region image is generated from the region image, for each set of the region images in a plurality of corresponding regions respectively corresponding to the plurality of focus images, based on the specific feature detected by the detection unit 43; and a generation unit 45 that generates the combination region image by combining the region images for each of the plurality of corresponding regions based on the parameter determined by the determination unit 44.

Various embodiments of the present invention relate to, among other things, systems for generating engineered water nanostructures (EWNS) comprising reactive oxygen species (ROS) and methods for inactivating at least one of viruses, bacteria, bacterial spores, and fungi in or on a wound of a subject in need thereof or on produce by applying EWNS to the wound or to the produce.
