Segmentation of diagnostic tissue compartments on whole slide images with renal thrombotic microangiopathies (TMAs) [PDF]
arXiv, 2023 The thrombotic microangiopathies (TMAs) manifest in renal biopsy histology with a broad spectrum of acute and chronic findings. Precise diagnostic criteria for a renal biopsy diagnosis of TMA are missing. As a first step towards a machine learning- and computer vision-based analysis of wholes slide images from renal biopsies, we trained a segmentation ...

Renal Parenchymal Area and Kidney Collagen Content [PDF]
arXiv, 2016 The extent of renal scarring in chronic kidney disease (CKD) can only be ascertained by highly invasive, painful and sometimes risky tissue biopsy. Interestingly, CKD-related abnormalities in kidney size can often be visualized using ultrasound. Nevertheless, not only does the ellipsoid formula used today underestimate true renal size but also the ...

Classification of histopathology images using ConvNets to detect Lupus Nephritis [PDF]
arXiv, 2021 Systemic lupus erythematosus (SLE) is an autoimmune disease in which the immune system of the patient starts attacking healthy tissues of the body. Lupus Nephritis (LN) refers to the inflammation of kidney tissues resulting in renal failure due to these attacks.

Extremely weakly-supervised blood vessel segmentation with physiologically based synthesis and domain adaptation [PDF]
arXiv, 2023 Accurate analysis and modeling of renal functions require a precise segmentation of the renal blood vessels. Micro-CT scans provide image data at higher resolutions, making more small vessels near the renal cortex visible. Although deep-learning-based methods have shown state-of-the-art performance in automatic blood vessel segmentations, they require ...

Trasplante renal: Dilemas y bioética
Revista Repertorio de Medicina y Cirugía, 2009 El progreso de la ciencia y en especial el de los trasplantes de riñón amerita muchas reflexiones éticas, pues no todos los dilemas que se presentan se han solucionado y algunos no han sido tomados como tales. Los donantes vivos pueden ser sujetos a coacción, pues adquieren un compromiso con la familia, la sociedad y el equipo de salud para donar su ...

Impact and safety outcomes of an intradialytic physical exercise program
Nefrología (English Edition), 2021 Introduction: Patients undergoing hemodialysis (HD) are characterized by a poor physical condition and a substantial sedentary profile. The implementation of physical exercise programs in the hemodialysis units is usually limited by the inherent safeness

Short- and Long-Term Statistical Properties of Heartbeat Time-Series in Healthy and Pathological Subjects [PDF]
arXiv, 2002 We analize heartbeat time-series corresponding to several groups of individuals (healthy, heart transplanted, with congestive heart failure (CHF), after myocardial infarction (MI), hypertensive), looking for short- and long-time statistical behaviors. In particular we study the persistency patterns of interbeat times and interbeat-time variations. Long-
