Neural Annotation Refinement: Development of a New 3D Dataset for Adrenal Gland Analysis

Pascal Fua, Jiancheng Yang, Pamuditha Udaranga Wickramasinghe

The human annotations are imperfect, especially when produced by junior practitioners. Multi-expert consensus is usually regarded as golden standard, while this annotation protocol is too expensive to implement in many real-world projects. In this study, w ...

Microsurgical resection of a radicular hemangioblastoma with subarachnoid hemorrhage: how I do it

Constantin Tuleasca

Background Hemangioblastomas (HBL) are benign tumors occurring sporadically or associated with Von Hippel-Lindau syndrome (VHL). Method We present the pre-, per-, and postoperative course of a rare case with radicular HBL presenting with subarachnoid hemor ...

The matricellular protein CYR61 interferes with normal pancreatic islets architecture and promotes pancreatic neuroendocrine tumor progression

Jelena Zaric

The significance of matricellular proteins during development and cancer progression is widely recognized. However, how these proteins actively contribute to physiological development and pathological cancer progression is only partially elucidated. In thi ...

Enzyme and Acid Deconjugation of Plasma Sulfated Metanephrines

Sandrine Gerber

Background: Total (i.e. free + sulfated) metanephrines in plasma is a biomarker for the diagnosis of pheochromocytoma/paraganglioma. Sulfated metanephrines must be completely deconjugated by perchloric acid hydrolysis or sulfatase treatment prior to analyt ...

Lack of Enantioselectivity in the SULT1A3-catalyzed Sulfoconjugation of Normetanephrine Enantiomers: An In Vitro and Computational Study

Sandrine Gerber, Jean-Baptiste Gualtierotti

(1R)-Normetanephrine is the natural stereoisomeric substrate for sulfotransferase 1A3 (SULT1A3)-catalyzed sulfonation. Nothing appears known on the enantioselectivity of the reaction despite its potential significance in the metabolism of adrenergic amines ...

Synthetic calibrators for the analysis of sulfoconjugated metanephrines in urine: hydrolysis conditions revisited

Sandrine Gerber, Jonathan Simonin

Background: The quantification of total (free + sulfated) metanephrines in urine is recommended to diagnose pheochromocytoma. Urinary metanephrines include metanephrine itself, normetanephrine and methoxytyramine, mainly in the form of sulfate conjugates ( ...

COUP-TFII Controls Mouse Pancreatic beta-Cell Mass through GLP-1-beta-Catenin Signaling Pathways

Anne Grapin-Botton

Background: The control of the functional pancreatic beta-cell mass serves the key homeostatic function of releasing the right amount of insulin to keep blood sugar in the normal range. It is not fully understood though how beta-cell mass is determined. ...

Immunoisolated xenogenic chromaffin cell therapy for chronic pain. Initial clinical experience

Patrick Aebischer, Julien Favre

BACKGROUND: Chromaffin cells from the adrenal gland secrete a mixture of compounds that have a strong analgesic effect, especially when administered intrathecally. Many studies in animal models have shown that discordant xenogeneic cell isolates, including ...
