Selective Breast Cancer Cell Capture, Culture, and Immunocytochemical Analysis Using Self-Assembled Magnetic Bead Patterns in a Microfluidic Chip

Martinus Gijs, Jean-Claude Bünzli, Caroline Vandevyver, Venkataragavalu Sivagnanam, Bo Song

Separation and subsequent culturing of MCF-7 breast cancer cells on self-assembled protein-coated magnetic beads in a microfluidic chip is demonstrated. The beads were patterned in situ inside a sealed microfluidic channel using magnetic-field-assisted ele ...

Structure and function of the olfactory bulb microcircuit

Michele Pignatelli

The aim of this study is to contribute to understand the physiology of the Olfactory System through detailed microcircuit investigation, adopting advanced electrophysiological and anatomical techniques. Multiple patch clamp recordings allow understanding t ...

Reconstructing the segmentation network in real space

Jonathan Bieler

The segmentation of the early Drosophila embryo has proven to be a fertile ground for experimentalists and modellers. Until now, most models have assumed a one-dimensional geometry along a portion of the anterior-posterior axis, motivated by the nearly rot ...

Intercellular calcium dynamics in smooth muscle cells

Dominique Seppey

Muscular arteries are able to actively modify their diameter by modulating the tone of the smooth muscle cells located within the arterial wall. A small variation of lumen diameter has a large influence on blood flow as well as on arterial pressure. The ca ...

Spatially Resolved Potential Distribution in Carbon Nanotube Cross-Junction Devices

Klaus Kern, Marko Burghard, Kannan Balasubramanian, Eduardo Jian Hua Lee

Crossed-nanotube junctions, the basic constituents of carbon nanotube networks, are investigated by scanning photocurrent microscopy. The location of the predominant electrostatic potential drop, at the electrical contacts or at the junction, is found to b ...

An Introduction To The Technology Of Thin Film Silicon Photovoltaics

Christophe Ballif, Franz-Josef Haug, Corsin Battaglia, Xavier Niquille, Matthieu Despeisse, Mathieu Gérard Boccard, Grégory Bugnon, Andrea Feltrin, Benjamin Strahm, Gaetano Parascandolo

Several aspects of the science and technology of thin film silicon for photovoltaic applications will be presented. The potential advantages of this technology over crystalline wafer technology will be discussed. A basic understanding of the material prope ...

Inferring connection proximity in networks of electrically coupled cells by subthreshold frequency response analysis

Henry Markram, Thomas Berger, Michele Giugliano, Corrado Cali, Michele Pignatelli

Electrical synapses continuously transfer signals bi-directionally from one cell to another, directly or indirectly via intermediate cells. Electrical synapses are common in many brain structures such as the inferior olive, the subcoeruleus nucleus and the ...

Long-term monitoring of post-stroke plasticity after transient cerebral ischemia in mice using in vivo and ex vivo diffusion tensor MRI

Pierre Magistretti

WE USED A MURINE MODEL OF TRANSIENT FOCAL CEREBRAL ISCHEMIA TO STUDY: 1) in vivo DTI long-term temporal evolution of the apparent diffusion coefficient (ADC) and diffusion fractional anisotropy (FA) at days 4, 10, 15 and 21 after stroke 2) ex vivo distribu ...

Myofibroblast communication is controlled by intercellular mechanical coupling

Jean-Jacques Meister, Boris Hinz, Sébastien Schaub, Lysianne Follonier Castella

Neoformation of intercellular adherens junctions accompanies the differentiation of fibroblasts into contractile myofibroblasts, a key event during development of fibrosis and in wound healing. We have previously shown that intercellular mechanical couplin ...

Shear stress and cyclic circumferential stretch, but not pressure, alter connexin43 expression in endothelial cells

Nikolaos Stergiopoulos, Paolo Silacci

Hemodynamic forces play a critical role in atherogenesis, as evidenced by the focal pattern of development of atherosclerotic lesions. Whereas disturbed flow in the branches and curved regions of large arteries is proatherogenic, laminar flow in the straig ...
