Early Cell Death Detection with Digital Holographic Microscopy

Pierre Magistretti, Christian Depeursinge, Nicolas Pavillon, Pierre Marquet, Pascal Jourdain, Corinne Moratal

Background: Digital holography provides a non-invasive measurement of the quantitative phase shifts induced by cells in culture, which can be related to cell volume changes. It has been shown previously that regulation of cell volume, in particular as it r ...

Stochastic modeling of salt accumulation in the root zone due to capillary flux from brackish groundwater

Andrea Rinaldo, Samir Suweis

[1] Groundwater can be a source of both water and salts in semiarid areas, and therefore, capillary pressure-induced upward water flow may cause root zone salinization. To identify which conditions result in hazardous salt concentrations in the root zone, ...

Benchmark of experimental techniques for measuring and controlling suction

Lyesse Laloui, Hervé Péron

The paper presents a benchmarking study carried out within the ‘Mechanics of Unsaturated Soils for Engineering’ (MUSE) network aimed at comparing different techniques for measurement and control of suction. Techniques tested by the eight ‘Mechanics of Unsa ...

Role of lymphatic vessels in tumor immunity: passive conduits or active participants?

Melody Swartz, Amanda Waite Lund

Research in lymphatic biology and cancer immunology may soon intersect as emerging evidence implicates the lymphatics in the progression of chronic inflammation and autoimmunity as well as in tumor metastasis and immune escape. Like the blood vasculature, ...

Transgenic mice and their impact on kidney research

Friedrich Beermann

The kidney is a key organ in the maintenance of ion and fluid homeostasis and specific transport systems localized along the nephron guarantee this function. Due to its large functional heterogeneity, experiments on the whole organ level cannot be easily p ...

The 4.5 angstrom structure of human AQP2

Henning Paul-Julius Stahlberg, Andreas Engel

Located in the principal cells of the collecting duct, aquaporin-2 (AQP2) is responsible for the regulated water reabsorbtion in the kidney and is indispensable for the maintenance of body water balance. Disregulation or malfunctioning of AQP2 can lead to ...

Interstitial flow as a guide for lymphangiogenesis

Melody Swartz

The lymphatic system is important in tissue fluid balance regulation, immune cell trafficking, edema, and cancer metastasis, yet very little is known about the sequence of events that initiate and coordinate lymphangiogenesis. Here, we characterize the pro ...

Aquaporins in brain: distribution, physiology, and pathophysiology

Pierre Magistretti

Water homeostasis in the brain is of central physiologic and clinical importance. Neuronal activity and ion water homeostasis are inextricably coupled. For example, the clearance of K+ from areas of high neuronal activity is associated with a concomitant w ...

Astrocyte-specific expression of aquaporin-9 in mouse brain is increased after transient focal cerebral ischemia

Pierre Magistretti

Aquaporin-9 (AQP9) is a new member of the aquaporin family of water-selective channels mainly expressed in liver and testis, presenting the characteristic of also being permeable to various solutes, particularly lactate. Recent data have shown the presence ...

The aquaporin sidedness revisited

Henning Paul-Julius Stahlberg, Andreas Engel

Aquaporins are transmembrane water channel proteins, which play important functions in the osmoregulation and water balance of microorganisms, plants, and animal tissues. All aquaporins studied to date are thought to be tetrameric assemblies of four subuni ...
