Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Comparative study of human erythrocytes by digital holographic microscopy, confocal microscopy, and impedance volume analyzer

Pierre Magistretti, Christian Depeursinge, Benjamin Rappaz, Pierre Marquet

Red blood cell (RBC) parameters such as morphology, volume, refractive index, and hemoglobin content are of great importance for diagnostic purposes. Existing approaches require complicated calibration procedures and robust cell perturbation. As a result, ...

Characterisation of tumour vasculature in mouse brain by USPIO contrast-enhanced MRI

Giulio Gambarota

To enhance the success rate of antiangiogenic therapies in the clinic, it is crucial to identify parameters for tumour angiogenesis that can predict response to these therapies. In brain tumours, one such parameter is vascular leakage, which is a response ...

Cellular dynamics explored with digital holographic microscopy

Benjamin Rappaz

Obtaining high resolution 3D quantitative images is critical for elucidating the relationship between cell dynamics and physiological or pathological processes. However the feasibility of such cellular dynamic studies is limited by the resolution of the 3D ...

Continuous separation of cells by balanced dielectrophoretic forces at multiple frequencies

Philippe Renaud, Thomas Michael Braschler, Nicolas Demierre

We present a particle-sorting device based on the opposition of dielectrophoretic forces. The forces are generated by an array of electrode chambers located in both sidewalls of a main flow channel. Particles with different dielectric response perceive dif ...

Extraction of haemoglobin from human blood by affinity precipitation using a haptoglobin-based stimuli-responsive affinity macroligand

Gisela Stocker Majd

Affinity precipitation was compared to affinity chromatography and batch adsorption as the final purification step in a protocol for the isolation of haemoglobin from human blood. Haptoglobin was the affinity ligand. The first steps on the process were rea ...

Simultaneous loss of beta- and gamma-catenin does not perturb hematopoiesis or lymphopoiesis

Freddy Radtke, Ute Koch, Anne Wilson

Hematopietic stem cells (HSCs) maintain life-long hematopoiesis in the bone marrow via their ability to self-renew and to differentiate into all blood lineages. Although a central role for the canonical wnt signaling pathway has been suggested in HSC self- ...

Hematopoietic Stem Cells Reversibly Switch from Dormancy to Self-Renewal during Homeostasis and Repair

Anne Wilson, Sandra Eloise Kjeldsen, Cyrille Dunant, Maike Jaworski

Bone marrow hematopoietic stem cells (HSCs) are crucial to maintain lifelong production of all blood cells. Although HSCs divide infrequently, it is thought that the entire HSC pool turns over every few weeks, suggesting that HSCs regularly enter and exit ...

All the Disorder Mechanisms in the 13:58 Phases Come Together. Out of the Modulated Confusion Rises the Remarkable Phase Ce12.60Cd58.68(2)

The compound

Ce_{12.60}Cd_{58.68(2)}

is a metrically commensurate representative of the incommensurately modulated phase

Ce_{13}Cd_{57+\delta}

. It is most likely a lock-in phase. The structure, which was solved using seeding of the modulation from thos ...

Microparticles in stored red blood cells: an approach using flow cytometry and proteomic tools

Niels Erik Lion, David Crettaz, Olivier Rubin

Background and Objectives Microparticles (MPs) are small phospholipid vesicles of less than 1 mu m, shed in blood flow by various cell types. These MPs are involved in several biological processes and diseases. MPs have also been detected in blood products ...

Plasmodium falciparum regulatory subunit of cAMP-dependent PKA and anion channel conductance

Malaria symptoms occur during Plasmodium falciparum development into red blood cells. During this process, the parasites make substantial modifications to the host cell in order to facilitate nutrient uptake and aid in parasite metabolism. One significant ...
