Bidirectional Transfer Study of Polystyrene Nanoparticles across the Placental Barrier in an ex Vivo Human Placental Perfusion Model

BACKGROUND: Nanoparticle exposure in utero might not be a major concern yet, but it could become more important with the increasing application of nanomaterials in consumer and medical products. Several epidemiologic and invitro studies have shown that nan ...

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 ...

Electroacoustic absorption: towards room equalization in the low-frequency range

Hervé Lissek

The occurrence of standing waves in room dramatically affects the sound rendering in the low-frequency range ([20-200 Hz]), and solutions of the state-of-the-art are incapable to damp such modes over the whole low-frequency band. This talk will present a n ...

MULTIFUNCTIONALIZED SPIONs FOR NUCLEAR TARGETING: CELL UPTAKE AND GENE EXPRESSION

Heinrich Hofmann, Jatuporn Salaklang, Alke Fink

Superparamagnetic iron oxide nanoparticles (SPIONs) are used in many biological applications, which necessitate intracellular targeting. Here, we investigate intracellular localization and gene expression in HeLa cells after treatment with functionalized S ...

Theory of percolation and tunneling regimes in nanogranular metal films

Claudio Grimaldi

Nanogranular metal composites, consisting of immiscible metallic and insulating phases deposited on a substrate, are characterized by two distinct electronic transport regimes depending on the relative amount of the metallic phase. At sufficiently large me ...

Plant nanobionics approach to augment photosynthesis and biochemical sensing

Ardemis Anoush Boghossian

The interface between plant organelles and non-biological nanostructures has the potential to impart organelles with new and enhanced functions. Here, we show that single-walled carbon nanotubes (SWNTs) passively transport and irreversibly localize within ...

Characterization of the surfaceome of the metal-reducing bacterium Desulfotomaculum reducens

Rizlan Bernier-Latmani, Romain Hamelin, Diego Chiappe, Elena Suvorova Buffat, Elena Cristina Dalla Vecchia, Paul Pao-Yun Shao

Desulfotomaculum reducens strain MI-1 is a Gram-positive, sulfate-reducing bacterium also capable of reducing Fe(III). Metal reduction in Gram-positive bacteria is poorly understood. Here, we investigated Fe(III) reduction with lactate, a non-fermentable s ...

Selective transport control on molecular velcro made from intrinsically disordered proteins

Sylvia Jeney

The selectivity and speed of many biological transport processes(1) transpire from a 'reduction of dimensionality'(2) that confines diffusion to one or two dimensions instead of three(3). This behaviour remains highly sought after on polymeric surfaces(4) ...

A Single-Cell Perspective on Non-Growing but Metabolically Active (NGMA) Bacteria

John McKinney, Giulia Manina

A long-standing and fundamental problem in microbiology is the non-trivial discrimination between live and dead cells. The existence of physically intact and possibly viable bacterial cells that fail to replicate during a more or less protracted period of ...

Microfluidic chip for monitoring Ca2+ transport through a confluent layer of intestinal cells

Martinus Gijs, Paolo Silacci, Hüseyin Cumhur Tekin, Josias Basil Wacker, Christine Ruffert, Guy Vergères

The absorption of dietary calcium through the intestinal barrier is essential for maintaining health in general and especially of the bone system. We propose a microfluidic model that studies free calcium (Ca2+) transport through a confluent monolayer of C ...
