Automatic analysis device
An automatic analysis device including a container filled with a fluid, a pressure source, a probe which separates the fluid within the container, the probe associated with a probe position, a motor which moves the probe, a flow path which connects the probe and the pressure source, the flow path associated with a flow path position, a pressure sensor which measures pressure variations within the flow path corresponding with time series management data, and a sensor which detects a liquid level position within the container. A condition of flow generated within the flow path is estimated based on (i) the time series measurement data and (ii) a reference value of pressure according to fluid pressure based on gravitational acceleration in a position of the pressure sensor calculated based on (a) the probe position or the flow path position and (b) an immersion depth of the probe determined by the sensor.

Automated analysis device, and analysis method
Since the measurement start timings for a plurality of specimens in different test fields deviate from one another, the measurement results are not coordinated, leading to a delay in reporting. When determining an order for measuring a newly recognized specimen using an automated analysis device capable of performing measurements in a plurality of test fields, the measurement order for specimens waiting to be measured is changed to minimize the time difference between measurement result output timings for a plurality of specimens for the same patient, with reference to specimen information such as urgent test information, a measurement completion time, and an earliest measurement completion time for other specimens, relating to the patient's other specimens having the same patient number in the specimen information.
Sample handling system for handling a plurality of samples
A sample handling system for handling samples is disclosed. The sample handling system comprises sample holders, each receives a sample container; a sample transport device for moving the sample holders; a control unit for controlling functionality of the sample handling system, and a monitoring system for monitoring the samples during movement. The monitoring system comprises a camera module for continuously capturing images of a part of the sample transport device, wherein the camera module is at a distance from the sample transport device such that the camera module has a free field of view to the sample transport device, and a processor for processing the captured images and determining an item of information about the sample transport device and/or the sample container and/or the sample from the captured images. The control unit retrieves the item of information from the processor. The controlling is based on the retrieved item of information.
Dimethylacrylamide (DMAA) hydrogel for expansion microscopy (ExM)
The invention provides a method for preparing an expanded cell or tissue sample suitable for microscopic analysis. Expanding the sample can be achieved by binding, e.g., anchoring, key biomolecules to a DMAA-TF polymer network and swelling, or expanding, the polymer network, thereby moving the biomolecules apart as further described herein. As the biomolecules are anchored to the polymer network isotropic expansion of the polymer network retains the spatial orientation of the biomolecules resulting in an expanded, or enlarged, sample.
