Visible spectrum extended-focus optical coherence microscopy for label-free sub-cellular tomography

Theo Lasser, Paul James Marchand, Arno Pino Bouwens, Daniel Pawel Szlag, Jérôme Extermann, Adrien Charles-François Raymond Descloux, David Nguyen, Miguel Sison, Séverine Coquoz

We present a novel extended-focus optical coherence microscope (OCM) attaining 0.7 μm axial and 0.4 μm lateral resolution maintained over a depth of 40 μm, while preserving the advantages of Fourier domain OCM. Our system uses an ultra-broad spectrum from ...

The eukaryotic promoter database in its 30th year: focus on non-vertebrate organisms

Giovanna Ambrosini, Philipp Bucher, René Dreos, Rouayda Cavin Perier, Romain Fernand Pietro Groux

We present an update of the Eukaryotic Promoter Database EPD (http://epd.vital-it.ch), more specifically on the EPDnew division, which contains comprehensive organisms-specific transcription start site (TSS) collections automatically derived from next gene ...

Spindle-shaped nanoscale yolk/shell magnetic stirring bars for heterogeneous catalysis in macro- and microscopic systems

Shuliang Yang, Li Peng, Fang Wei

A new type of spindle-shaped nanoscale yolk/shellmagnetic stirring bar containing noblemetal nanoparticles was prepared. The as-synthesized Pd-Fe@meso-SiO2 not only showed impressive activity and stability as a heterogeneous catalyst in a macroscopic flask ...

A microfluidic cell-trapping device for single-cell tracking of host-microbe interactions

John McKinney, Jean-Baptiste Bureau, Matthieu Jean-Hubert Delincé, Thierry Soldati

The impact of cellular individuality on host-microbe interactions is increasingly appreciated but studying the temporal dynamics of single-cell behavior in this context remains technically challenging. Here we present a microfluidic platform, InfectChip, t ...

Phenotypic heterogeneity in metabolic traits among single cells of a rare bacterial species in its natural environment quantified with a combination of flow cell sorting and NanoSIMS

Anders Meibom, Stéphane Laurent Escrig, Martin Ackermann

Populations of genetically identical microorganisms residing in the same environment can display marked variability in their phenotypic traits; this phenomenon is termed phenotypic heterogeneity. The relevance of such heterogeneity in natural habitats is u ...

Long-term culture and high-resolution imaging of C. elegans using an automated microfluidic platform

Johan Auwerx, Martinus Gijs, Matteo Cornaglia, Laurent Mouchiroud, Govindan Narayanan Krishnamani

The nematode Caernohabditis elegans is one of the most employed small model organisms in biology. Studies on transgenic animals often require the accurate observation of highly localized fluorescent signals inside the worms at high magnification, hence dem ...

Overcoming inefficient secretion of recombinant VEGF-C in baculovirus expression vector system by simple purification of the protein from cell lysate

Witold Waldemar Kilarski

The first reports about successfully expressed recombinant proteins with the use of a baculovirus vector were published over 30 years ago. Despite the long time of refining this expression system, early problems with the production of baculovirus-derived s ...

Enzyme SU-8 microreactors: simple tools for cell-culture monitoring

Nico de Rooij, Peter Van der Wal, Sara Talaei, Martha Liley

Monitoring metabolism fluctuations inside a cell culture is a valuable method for assessment of the cells vitality. Enzyme-based biosensors can provide selective measurement of metabolites such as glucose, lactate, glutamate and choline. However, integrati ...

Compartmentalized Microfluidics for In Vitro Alzheimer’s Disease Studies

Philippe Renaud, Anja Kunze, Yufei Ren

Compartmentalized microfluidic devices are designed to engineer the cellular environment for cell cultures. The practical use of the compartmentalized chambers can be expanded to induce co-pathological cell cultures, where one cell population expresses a s ...

Murine ovarian follicle culture in PEG-hydrogel: Effects of mechanical properties and the hormones FSH and LH on development

Jeffrey Alan Hubbell, Seung Tae Lee, Jong Eun Ihm

The development of an in vitro culture system, comparable to the in vivo environment in terms of effects on oocyte growth and development, could provide a valuable experimental tool for studying the mechanisms governing oocyte development as well as practi ...
