The invention provides systems and methods for analyzing viruses by representing viral genetic diversity with a directed acyclic graph (DAG), which allows genetic sequencing technology to detect rare variations and represent otherwise difficult-to-document diversity within a sample. Additionally, a host-specific sequence DAG can be used to effectively segregate viral nucleic acid sequence reads from host sequence reads when a sample from a host is subject to sequencing. Known viral genomes can be represented using a viral reference DAG and the viral sequence reads from the sample can be compared to viral DAG to identify viral species or strains from which the reads were derived. Where the viral sequence reads indicate great genetic diversity in the virus that was infecting the host, those reads can be assembled into a DAG that itself properly represents that diversity.

This document provides methods and materials related to genetic variations of neurological disorders. For example, this document provides methods for using such genetic variations to assess susceptibility of developing Parkinson's disease.

A cancer test device (1) is provided with: an application unit (40) for applying a staining agent (45), which can selectively stain a product of a cancer-relating gene in a living cell a chromatic color, onto a group of living cells; an imaging unit (10) for imaging the group of living cells having the staining agent (45) applied thereto; and a determination unit (52) for determining the level of malignancy of cancerization of the group of living cells on the basis of the state of the stained expression pattern of the cancer-relating gene in the group of living cells in an image obtained by the aforementioned imaging.

In a configuration for analyzing data of cells measured by a cell measuring apparatus, accuracy of cell classification is improved without requiring the cell measuring apparatus to have high information processing capability. A cell analysis method, using a cell analyzer for analyzing cells in accordance with an artificial intelligence algorithm, includes: obtaining the data regarding the cells measured by the cell measuring apparatus; analyzing the data to generate information regarding a cell type of each of the cells; and transmitting the information to the cell measuring apparatus.

Methods for improving clinical diagnostic tests are provided, along with associated diagnostic techniques.

The invention provides systems and methods for determining patterns of modification to a genome of a subject by representing the genome using a graph, such as a directed acyclic graph (DAG) with divergent paths for regions that are potentially subject to modification, profiling segments of the genome for evidence of epigenetic modification, and aligning the profiled segments to the DAG to determine locations and patterns of the epigenetic modification within the genome.

Among the various aspects of the present disclosure is the provision of a hydrogel-based substrate comprising an aldehyde-containing component, such as N-ethanal acrylamide. The hydrogel component allows for functionalization of a hydrogel through conjugation of proteins (e.g., collagen) to the hydrogel in the absence of a post hoc crosslinking component.

The present invention is related to a biochip and production method thereof. The biochip comprises a carrier, a cell or tissue culture area deposited on the carrier, and a sensor area deposited on the carrier adjacent and fluidly communicating with the cell or tissue culture area. A containing space is contained in the cell or tissue culture area comprising a simulated vascular channel, a cell or a tissue and a culture medium. At least one sensor fixation area is contained at the sensor area for placing a sensor element. The present invention can be a model for stimulating cancer of specific patient to realtimely reflecting the cancer formation, transferring status and treatment strategies. The biochip could also carry testing drugs to observe how the drugs functioning to the cells/tissue as to provide a more accurate instruction of the drugs. The present invention can perform multiple test just within on chip which can save cost and also provide a more accurate test model for the patient.

Provided is an information processing apparatus including an information acquisition section (104) that acquires information of a first region (700) specified by a filling input operation on image data (610) of a living tissue by a user, and a region determination section (108) that executes fitting on a boundary of the first region on the basis of the image data and information of the first region and determines a second region (702) to be subjected to predetermined processing.
