This paper describes two novel ImageJ plugins for 'Clock Scan' image analysis. These plugins expand the functionality of the original visual basic 6 program and, most importantly, make the program available to a large research community by bundling it with the ImageJ free image analysis software package.

The Sense of Self: Reflected Self-Appraisal and Social Comparison

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

An infinite series composed of positive terms may either approach a finite value or increase without bound. Determining which outcome occurs is a central task in calculus, and comparison tests provide structured methods for making this determination. Rather than evaluating a series directly, these tests relate it to another series whose behavior is already known, allowing conclusions to be drawn through logical comparison.The direct comparison test applies to series with positive terms. If each...

Automated Analysis of Intracellular Phenotypes of Salmonella Using ImageJ

Salmonella invades and replicates inside intestinal epithelial cells both in Salmonella-specific vacuoles and free in the cytosol (hyper-replication). A high-throughput fluorescence microscopy-based protocol is described here to quantify the intracellular phenotypes of Salmonella by two complementary image analyses through ImageJ, reaching single-cell resolution and scoring.
FAQs
Consistent scale and acquisition conditions make measurements comparable across biological images. In ImageJ comparison workflows, researchers can standardize image scale before evaluating size or spatial organization, while consistent acquisition conditions reduce differences caused by imaging rather than biology. This preparation supports more reliable comparisons between samples and strengthens documentation of reproducible analysis methods.
Alignment places datasets in corresponding spatial positions, and overlays make their relationships easier to inspect. Difference images then emphasize locations where pixel values or structures diverge, helping reveal changes that visual inspection may miss. These operations are especially useful when comparing tissue organization, cell morphology, or fluorescence patterns across biological samples.
Region-of-interest analysis isolates a defined part of an image for focused measurement, while profile plots show how a value changes across a selected path or location. Together with pixel-intensity comparisons, these tools can distinguish localized fluorescence changes from broader patterns. The resulting measurements add quantitative detail to observations of biological structure and signal.
First standardize the image scale and confirm that acquisition conditions are suitable for comparison. Align or overlay the datasets, then select an appropriate region of interest or measurement approach. Pixel intensities, structural dimensions, or spatial patterns can be compared directly, with difference images and profile plots used to document additional changes.
ImageJ comparison can provide evidence about changes in cell morphology, fluorescence signal, tissue organization, or treatment response. Size measurements address structural change, pixel-intensity measurements address signal differences, and spatial comparisons address organization. Difference images, region-of-interest results, and profile plots provide complementary outputs, connecting visual changes with measurable image features.
In biology, the approach supports microscopy studies where samples may differ in form, signal, or arrangement. Researchers can apply it to compare cell morphology, evaluate fluorescence, examine tissue organization, or assess responses to treatment. Standardized measurements help separate biologically relevant differences from inconsistent analysis practices and make the method easier to describe and reproduce.
