RoundMi: A quantitative method to analyze mitochondrial morphology in mitotic cells

FEBS Open Bio, EarlyView.
RoundMi is a workflow for rapid analysis of mitochondrial morphology in mitotic cells. By combining adaptive preprocessing with automated segmentation and quantification, it enables accurate measurements from single focal plane images, reducing acquisition time and computational demands while remaining compatible with high‐throughput fixed and live ...

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

FEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Aquaporin‐3 and aquaporin‐5 impact the development of pancreatic ductal adenocarcinoma spheroids

FEBS Open Bio, EarlyView.
Schematic representation of the role of aquaporin‐3 (AQP3) and aquaporin‐5 (AQP5) in pancreatic ductal adenocarcinoma (PDAC). Both proteins are upregulated in PDAC and are associated with tumor progression and metastatic potential. Silencing AQP3 or AQP5 in PDAC spheroids results in decreased diameter, area, and overall growth, underscoring their key ...

Hyperactive ice‐binding proteins stabilize cell membranes and improve resistance to dehydration stress in Caenorhabditis elegans

FEBS Open Bio, EarlyView.
TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.

Direct imaging of explosives

Applied Radiation and Isotopes, 2000
Any technique that can detect nitrogen concentrations can screen for concealed explosives. However, such a technique would have to be insensitive to metal, both encasing and incidental. If images of the nitrogen concentrations could be captured, then, since form follows function, a robust screening technology could be developed.

Directional Watermarks in Images

2005 IEEE International Symposium on Circuits and Systems, 2005
A new watermark scheme based on directional filter banks and wavelet subband decomposition techniques is proposed. In order to embed the mark into the directional subband images, a projection classification algorithm is presented. These subband images with a particular directional property can prevent unauthorized use attacks.

Image Segmentation with Directed Trees

IEEE Transactions on Pattern Analysis and Machine Intelligence, 1980
This correspondence presents a simple algorithm to detect and label homogeneous areas in an image, using directed trees for region labeling. The scheme constructs directed trees with the image points as nodes, guided by an edge value computed at every point. These directed trees segment the image into disjoint regions.

Principle of Superposition by Direction Images

IEEE Transactions on Image Processing, 2011
This paper discusses the decomposition of the image by direction images, which is based on the concept of the tensor representation and its advanced form, the paired representation. The 2-D image is considered of the size N×N, where N is prime, a power of two, and a power of odd primes.

Future directions in imaging pouches

Abdominal Radiology, 2023
The sections of this special issue on the ileal pouch demonstrate that in the nearly 45 years since the ileal pouch has been utilized to treat patients with colitis and familial adenomatous polyposis, a substantial number of patients experience both short- and long-term morbidity and that imaging plays an important role in their management.

A score for directional dominance in images

2017 25th Signal Processing and Communications Applications Conference (SIU), 2017
The aim of this study is to develop a score calculation method for expressing directional dominance in the images. It is predicted that this score will give an information of how much improvement in system performance can be achieved when using a directional total variation-based regularization instead of a total variation.
