Shape-Aware Adversarial Learning for Scribble-Supervised Medical Image Segmentation with a MaskMix Siamese Network: A Case Study of Cardiac MRI Segmentation.
Bioengineering (Basel)
November 2024
College of Computer Science and Technology, National University of Defense Technology, Changsha 410073, China.
The transition in medical image segmentation from fine-grained to coarse-grained annotation methods, notably scribble annotation, offers a practical and efficient preparation for deep learning applications. However, these methods often compromise segmentation precision and result in irregular contours. This study targets the enhancement of scribble-supervised segmentation to match the accuracy of fine-grained annotation.

Virchows Arch
November 2024
Department of Pathology, Hospital of the University of Pennsylvania, Philadelphia, PA, USA.
Article Synopsis
- Psammoma bodies (PB) are often thought to be signs of a type of thyroid cancer called papillary thyroid carcinoma (PTC), but they can also appear in non-cancerous thyroid problems.
- A study looked at 26 patients with PB found in harmless thyroid conditions, showing that PB can also be present in cases like thyroid nodules and Hashimoto's disease.
- To be sure there's no cancer, doctors need to examine the whole thyroid and not just look for PB, since sometimes these bodies are found in people who don’t have cancer at all.
Puncture Wound Hemostasis and Preparation of Samples for Montaged Wide-Area Electron Microscopy Analysis.
J Vis Exp
May 2024
Department of Physiology and Cell Biology, University of Arkansas for Medical Sciences;
Hemostasis, the process of normal physiological control of vascular damage, is fundamental to human life. We all suffer minor cuts and puncture wounds from time to time. In hemostasis, self-limiting platelet aggregation leads to the formation of a structured thrombus in which bleeding cessation comes from capping the hole from the outside.

Work
November 2024
Department of Design, Indian Institute of Technology (IIT) Guwahati, Guwahati, Assam, India.
Article Synopsis
- The FMCG manufacturing sector in developing countries relies heavily on manual labor, leading to safety risks due to non-standardized work practices, especially during the hazardous rework of defective pouches.
- This research aims to improve occupational safety through innovative product design targeting ergonomic concerns in small-scale FMCG units.
- An ergonomic audit identified key safety issues, and a context-specific tool was developed and successfully trialed, demonstrating enhanced safety and productivity during the rework process.
