A Cell Atlas for the Mouse Brain

Henry Markram, Daniel Keller, Marc-Oliver Gewaltig

Despite vast numbers of studies of stained cells in the mouse brain, no current brain atlas provides region-by-region neuron counts. In fact, neuron numbers are only available for about 4% of brain of regions and estimates often vary by as much as 3-fold. ...

Depth-dependent mechanical properties of human articular cartilage obtained by indentation measurements

Pierre-Etienne Bourban, Lee Ann Laurent-Applegate, Matteo Gregorio Modesto Marascio, Robin Martin, Jens Antons

Emerging 3D printing technology permits innovative approaches to manufacture cartilage scaffolds associated with layer-by-layer mechanical property adaptation. However, information about gradients of mechanical properties in human articular cartilage is li ...

Influence of DNA Binding Dyes on Bare DNA Structure Studied with Atomic Force Microscopy

Giovanni Dietler, Aleksandre Japaridze, Aleksandr Benke, Sylvain Renevey

Fluorescent dyes are widely used for staining and visualization of DNA in optical microscopy based methods. Even though for some dyes the mechanism of binding is known, how this binding affects DNA remains poorly understood. Here we present a novel experim ...

SiR–Hoechst is a far-red DNA stain for live-cell nanoscopy

Kai Johnsson, Luc Reymond, Alberto Schena, Grazvydas Lukinavicius

Cell-permeable DNA stains are popular markers in live-cell imaging. Currently used DNA stains for live-cell imaging are either toxic, require illumination with blue light or are not compatible with super-resolution microscopy, thereby limiting their utilit ...

Distributor of neurons in a neocortical column

Henry Markram, Felix Schürmann, Georges Khazen, Martin Telefont

Computer-implemented methods, software, and systems for determining a distribution of neuronal cells across a portion of a brain are described. One computer-implemented method for determining a target distribution of one or more neuronal cells across a por ...

Focused light delivery and all optical scanning from a multimode optical fiber using digital phase conjugation

Demetri Psaltis, Christophe Moser, Salma Farahi

We demonstrate a digital phase conjugation technique for generating a sharp focus point at the end of a multimode optical fiber. A sharp focus is experimentally obtained at the distal end of a 200 mu m core multimode fiber. By recording the digital hologra ...

Inference about the number of contributors to a DNA mixture: Comparative analyses of a Bayesian network approach and the maximum allele count method

Kjell Konis

In the forensic examination of DNA mixtures, the question of how to set the total number of contributors (N) presents a topic of ongoing interest. Part of the discussion gravitates around issues of bias, in particular when assessments of the number of cont ...

Dynamic measurement of the height and volume of migrating cells by a novel fluorescence microscopy technique

Jean-Jacques Meister, Chiara Gabella, Alexander Verkhovskiy, Lara Buscemi Estefanell, Benoît Vianay

We propose a new technique to measure the volume of adherent migrating cells. The method is based on a negative staining where a fluorescent, non-cell-permeant dye is added to the extracellular medium. The specimen is observed with a conventional fluoresce ...

Altered branching patterns of Purkinje cells in mouse model for cortical development disorder

Giorgio Margaritondo

Disrupted cortical cytoarchitecture in cerebellum is a typical pathology in reeler. Particularly interesting are structural problems at the cellular level: dendritic morphology has important functional implication in signal processing. Here we describe a c ...
