SYSTEM FOR DETERMINING MULTINUCLEATED STATE OF MYOBLAST CELLS
A stable and efficient system that determines a multinucleated state of myoblast cells, the system including a storage unit that stores a cell culture substrate containing the myoblast cells, a measurement unit that measures a shape of the myoblast cells, and an analysis unit that calculates the number of nuclei in the individual myoblast cells based on a parameter.
Vacuum manifold for filtration microscopy
A vacuum manifold for filtration microscopy includes a manifold top having multiple openings, and a capture membrane positioned above and spaced apart from the manifold top, where the capture membrane is configured to deflect into contact with a surface of the manifold top when a negative pressure is applied to the multiple openings. A method for filtration microscopy includes the steps of providing a vacuum manifold including a manifold top having a plurality of openings, and a capture membrane positioned above and spaced apart from the manifold top; applying sample drops to sample spots on the membrane, the sample spots positioned above the plurality of openings; applying a negative pressure to the openings such that the capture membrane contacts a surface of the manifold top; and optically imaging particulates on the capture membrane.
Differential emissivity based evaporable particle measurement
A differential emissivity imaging device for measuring evaporable particle properties can include a heated plate, a thermal camera, a memory device, and an output interface. The heated plate can have an upper surface oriented to receive falling evaporable particles. The evaporable particles have a particle emissivity and the upper surface has a plate surface emissivity. The thermal camera can be oriented to produce a thermal image of the upper surface. A memory device can include instructions that cause the imaging device to calculate a mass of the individual evaporable particle via heat conduction using a calculated surface area and an evaporation time.

LENS-FREE IMAGING SYSTEM COMPRISING A DIODE, A DIAPHRAGM, AND A DIFFUSER BETWEEN THE DIODE AND THE DIAPHRAGM
This lensless imaging system comprises a receiving support configured to receive a sample, a light source configured to emit a light beam illuminating the sample in an illumination direction, the light source including a diode and a diaphragm, the diaphragm being positioned between the diode and the receiving support in the lighting direction, and a matrix photodetector configured to acquire at least one image of the sample, each image being formed by radiation emitted by the illuminated sample and including at least one elementary diffraction pattern, the receiving support being positioned between the light source and the matrix photodetector in the illumination direction.
The system further comprises a light diffuser positioned between the diode and the diaphragm.
Enhancing Flow Cytometry Discrimination with Geometric Transformation
In flow cytometry, particles (2) can be distinguished between populations (8) by combining n-dimensional parameter data, which may be derived from signal data from a particle, to mathematically achieve numerical results representative of an alteration (48). An alteration may include a rotational alteration, a scaled alteration, or perhaps even a translational alteration. Alterations may enhance separation of data points which may provide real-time classification (49) of signal data corresponding to individual particles into one of at least two populations.
CELL IMAGING DEVICE, CELL IMAGING METHOD, AND SAMPLE CELL
Provided are a cell imaging device and a cell imaging method that can shorten the time period of taking images of cells in a liquid sample, compared with conventional techniques. This cell imaging device introduces a urine sample containing cells into an internal space of a sample cell, moves at least one of the sample cell and an objective lens in a second direction while at least one of the sample cell and the objective lens is moved in a first direction, the second direction being different from the first direction, and takes, at a plurality of imaging positions, images of cells contained in the urine sample by means of an imaging unit.
