RefineCatDiff: Toward High‐Quality Medical Image Segmentation via a Categorical Diffusion Refinement Framework

Advanced Intelligent Systems, EarlyView.
This study proposes RefineCatDiff, a refinement framework for high‐quality medical image segmentation. By developing a categorical distribution‐based discrete diffusion process for refinement, the framework aligns well with the characteristics of image segmentation tasks. Experimental results on multiple datasets across different modalities demonstrate

A Robotic Urinary Bladder Enabling Volume Monitoring and Assisted Micturition

Advanced Intelligent Systems, EarlyView.
An implantable robotic bladder is presented that can store urine in an origami‐designed enclosure. An inductance sensing principle can monitor and transfer the urine volume in real‐time. It can actively expand based on the amount of urine collected from kidneys and apply on‐demand mechanical compression to assist urination.

Squamous Cell Carcinoma of the Renal Pelvis Associated with Kidney Stones: Radiologic Imaging Features with Gross and Histopathological Correlation

Journal of Clinical Imaging Science, 2013
Squamous cell carcinoma (SCC) of the renal pelvis is a rare neoplasm and is usually associated with long standing renal stone disease. This tumor is aggressive in nature and usually has a poor prognosis.

Ultra‐Efficient Kidney Stone Fragment Removal via Spinner‐Induced Synergistic Circulation and Spiral Flow

Advanced Intelligent Systems, EarlyView.
Leveraging spinning‐induced localized suction, the spinner device enables ultra‐efficient removal of kidney stone fragments, capturing a larger quantity of fragments from distances exceeding 20 mm. The spinner significantly improves the efficiency and effectiveness of stone fragment removal by reducing operative time, increasing stone‐free rates, and ...

Alpha adrenergic receptors in renal pelvis and calyces: can rat models be used?

International Brazilian Journal of Urology, 2014
We aimed, in this study, to determine the distribution of α-1 AR subtypes in rat and human pelvis and calyces, and to evaluate, by comparing these two species, the possibility of rats to be used as models for humans.

Facts and Misfacts on D‐Dimer Testing. Consensus Guidance From the Italian Society on Thrombosis and Hemostasis (SISET)

American Journal of Hematology, EarlyView.
ABSTRACT D‐dimer defines degradation products derived from the proteolysis mediated by plasmin on cross‐linked fibrin. The evidence‐based use of D‐dimer in some conditions has been consolidated. Currently, however, there is an entrenched prescription of D‐dimer testing to screen otherwise healthy subjects that may induce prescribing physicians to start

Intestinal Atresia in PPP1R12A‐Related Urogenital and Brain Malformation Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT PPP1R12A‐related urogenital and brain malformation syndrome (UBMS) is a newly described disorder characterized by congenital anomalies primarily involving the urogenital system and the brain. We describe a preterm female neonate with multiple congenital anomalies, including type IIIb jejunal atresia, incomplete intestinal rotation, imperforate
