Article Abstract
Three-dimensional structures in biological systems are routinely evaluated using large image stacks acquired from fluorescence microscopy; however, analysis of such data is muddled by variability in the signal across and between samples. Here, we present Intensify3D: a user-guided normalization algorithm tailored for overcoming common heterogeneities in large image stacks. We demonstrate the use of Intensify3D for analyzing cholinergic interneurons of adult murine brains in 2-Photon and Light-Sheet fluorescence microscopy, as well as of mammary gland and heart tissues. Beyond enhancement in 3D visualization in all samples tested, in 2-Photon in vivo images, this tool corrected errors in feature extraction of cortical interneurons; and in Light-Sheet microscopy, it enabled identification of individual cortical barrel fields and quantification of somata in cleared adult brains. Furthermore, Intensify3D enhanced the ability to separate signal from noise. Overall, the universal applicability of our method can facilitate detection and quantification of 3D structures and may add value to a wide range of imaging experiments.

Significance: Melanoma's rising incidence demands automatable high-throughput approaches for early detection such as total body scanners, integrated with computer-aided diagnosis. High-quality input data is necessary to improve diagnostic accuracy and reliability.
Aim: This work aims to develop a high-resolution optical skin imaging module and the software for acquiring and processing raw image data into high-resolution dermoscopic images using a focus stacking approach.

Purpose: Gadoxetic acid-enhanced hepatobiliary phase T-weighted (Tw) MRI is effective for the detection of focal liver lesions but lacks sufficient T contrast to distinguish benign from malignant lesions. Although the addition of T, diffusion, and dynamic contrast-enhanced Tw imaging improves lesion characterization, these methods often do not provide adequate spatial resolution to identify subcentimeter lesions. This work proposes a high-resolution, volumetric, free-breathing liver MRI method that produces colocalized fat-suppressed, variable Tw images from a single acquisition, thereby improving both lesion detection and characterization.

Embryonic tissue growth and patterning are largely controlled by signals exchanged locally between cell populations within the tissues themselves. Cytonemes are a type of signaling filopodia first identified in Drosophila that connect and mediate exchange between signal-producing and signal-receiving cells. In the developing Drosophila wing imaginal disc, cytonemes are involved in signal exchange between distinct populations of cells within the disc proper (DP) epithelium, which will form the adult wing, as well as between DP cells and cells in adjacent disc-associated tissues.

Purpose: Recent developments in computational pathology have been driven by advances in vision foundation models (VFMs), particularly the Segment Anything Model (SAM). This model facilitates nuclei segmentation through two primary methods: prompt-based zero-shot segmentation and the use of cell-specific SAM models for direct segmentation. These approaches enable effective segmentation across a range of nuclei and cells.
