Experimental characterization of the distribution of collagen fiber recruitment

Nikolaos Stergiopoulos, Sylvain Roy, Christophe Boss

The passive biomechanical behavior of blood vessels is generally modeled by a parallel arrangement of elastin and collagen, with collagen recruitment depending on vessel strain. We experimentally determined the collagen recruitment distribution using confo ...

Dual-mode digital holographic and fluorescence microscopy for the study of morphological changes in cells under simulated microgravity

Christian Depeursinge, Christophe Pache, Jonas Kühn, Muhammed Fatih Toy, Jérôme Parent, Marcel Egli

A dual mode microscope is developed to study morphological evolution of mouse myoblast cells under simulated microgravity in real time. Microscope operates in Digital Holographic Microscopy (DHM) and widefield epifluorescence microscopy modes in a time seq ...

Characterization of the cytotoxicity and imaging properties of secondharmonic nanoparticles

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh

We develop second-harmonic nanoparticles as the contrast agents for cell imaging. Second-harmonic nanoparticles show promise as cell imaging probes due to their non-bleaching, non-blinking, and coherent signal. Nanoparticles of noncentrosymmetric crystal s ...

An optical and microPET assessment of thermally-sensitive liposome biodistribution in the Met-1 tumor model: Importance of formulation

Henning Paul-Julius Stahlberg, Hua Zhang, Jin Won Seo

The design of delivery vehicles that are stable in circulation but can be activated by exogenous energy sources is challenging. Our goals are to validate new imaging methods for the assessment of particle stability, to engineer stable and activatable parti ...

Accelerated Wavelet-Regularized Deconvolution for 3-D Fluorescence Microcopy

Michaël Unser, Matthieu Guerquin-Kern, Ilker Bayram, Raquel Terrés Cristofani

Modern deconvolution algorithms are often specified as minimization problems involving a non-quadratic regularization functional. When the latter is a wavelet-domain

A protocol for preparing GFP-labeled neurons previously imaged in vivo and in slice preparations for light and electron microscopic analysis

Graham Knott, Egbert Welker

In vivo imaging of green fluorescent protein (GFP)-labeled neurons in the intact brain is being used increasingly to study neuronal plasticity. However, interpreting the observed changes as modifications in neuronal connectivity needs information about syn ...

Surface-Functionalized Ultrasmall Superparamagnetic Nanoparticles as Magnetic Delivery Vectors for Camptothecin

Heinrich Hofmann

The linking of therapeutic drugs to ultrasmall superparamagnetic iron oxide nanoparticles (USPIOs) allowing intracellular release of the active drug via cell-specific mechanisms would achieve tumor-selective magnetically-enhanced drug delivery. To validate ...

Towards in vivo small animal imaging

Theo Lasser, Michael Friedrich, Rainer Leitgeb, Anne Grapin-Botton, Martin Villiger, Joan Goulley

Fourier domain Optical coherence microscopy (FDOCM) offers excellent sensitivity and high axial resolution to image the structure of biological tissue. The depth information is extracted in parallel and allows very high volume acquisition rates. An illumin ...

Comparison of ALA- and ALA hexyl-ester-induced PpIX depth distribution in human skin carcinoma

Hubert van den Bergh, Georges Wagnières, Matthieu Philippe Emmanuel Zellweger, Tanja Gabrecht

Photodynamic therapy (PDT) based on the use of photoactivable porphyrins, such as protoporphyrin IX (PpIX), induced by the topical application of amino-levulinic acid (ALA) or its derivatives, ALA methyl-ester (m-ALA), is a treatment for superficial basal ...
