In this study, the use of an in situ loading device coupled with micro-X-ray computed tomography for fibrous joint biomechanics will be discussed. Experimental readouts identifiable with an overall change in joint biomechanics will include: 1) reactionary force vs. displacement, i.e. tooth displacement within the alveolar socket and its reactionary response to loading, 2) three-dimensional (3D) spatial configuration and morphometrics, i.e. geometric relationship of the tooth with the alveolar...

We developed a software platform that utilizes Imaris Neuroscience, ImarisXT and MATLAB to measure the changes in morphology of an undefined shape taken from three-dimensional confocal fluorescence of single cells. This novel approach can be used to quantify changes in cell shape following receptor activation and therefore represents a possible additional tool for drug discovery.

FAQs
An x–t image places spatial position along the selected line on one axis and elapsed time on the other. Changes in signal intensity can therefore be followed as they occur at particular locations. This combined view helps distinguish where a cellular or molecular event occurs from when it occurs, supporting analysis of movement and rapidly changing fluorescence signals.
Because the microscope repeatedly revisits one defined line, measurements are concentrated on that spatial region over time. This provides high temporal resolution for rapid changes that might not be captured between conventional image frames. The approach is especially useful when the key behavior occurs along a membrane, within a moving cell, or along a pathogen-associated trajectory.
Signal intensity changes provide a time-resolved readout of dynamic fluorescence or molecular behavior at defined positions. Examining these changes together with spatial location can reveal when a signal appears, shifts, or varies along the scanned line. In immunology and infection studies, this supports analysis of receptor movement, pathogen movement, and membrane interactions.
A line positioned across a region of interest can record how an immune cell or its associated signal changes over time. The resulting spatial-temporal record helps researchers examine movement along the selected path rather than relying only on separate frames. This makes the method relevant for quantifying immune-cell motility and relating movement to dynamic cellular signals.
A researcher first defines the spatial line that contains the behavior of interest, then configures the microscope to scan that same line repeatedly. Signal intensity is recorded at successive time points, and the measurements are assembled into an x–t image, also called a kymograph. The image can then be examined for spatially localized temporal changes.
This method is useful when the experiment focuses on rapid events involving immune cells, receptors, pathogens, or cellular membranes. It can be selected to follow motility, movement of a receptor or pathogen, membrane interactions, or changing fluorescence signals. Its value is greatest when temporal detail along a defined spatial region matters more than observing only separate full-frame images.
Xt Line Imaging provides a spatially and temporally resolved record of host–pathogen behavior. Researchers can use it to examine pathogen movement, interactions with immune-cell membranes, receptor dynamics, and associated fluorescence changes. By combining position with timing, the method supports more precise analysis of interaction events that may be difficult to resolve with conventional frame-based imaging alone.
