Pulsatile blood flow in human bone assessed by laser-Doppler flowmetry and the interpretation of photoplethysmographic signals

Dimitri Nestor Alice Van De Ville, Jean-Noël Hyacinthe, Jonas Richiardi

Human bone blood flow, mean blood speed and the number of moving red blood cells were assessed (in arbitrary units), as a function of time, during one cardiac cycle. The measurements were obtained non-invasively on five volunteers by laser-Doppler flowmetr ...

Dental Phenotype in Jalili Syndrome Due to a c.1312 dupC Homozygous Mutation in the CNNM4 Gene

Jalili syndrome denotes a recessively inherited combination of an eye disease (cone-rod dystrophy) and a dental disorder (amelogenesis imperfecta), which is caused by mutations in the CNNM4 gene. Whereas the ophthalmic consequences of these mutations have ...

Elucidating the role of neuron-astrocyte metabolic coupling in learning and memory

Monika Tadi

The brain has very high energy demands that are mainly met by the circulating blood glucose to ensure its proper functioning. Thus, it is not surprising that though the human brain weighs only 2- 3% of the body weight, it consumes approximately 25% of tota ...

Comparative Study on the In Vitro Cytotoxicity of Linear, Dendritic, and Hyperbranched Polylysine Analogues

Harm-Anton Klok, Florian Maria Wurm, David Hacker, Lucia Baldi Unser, Zuzana Kadlecova

Lysine-based polycations are widely used as nonviral carriers for gene delivery. This manuscript reports the results of a comparative study on the in vitro cytotoxicity of a library of three structural polylysine variants, namely, linear polylysine (LPL), ...

Mathematical Modeling of Brain Energy Metabolism, Measured with PET and MRS in Rodents

Bernard Lanz

Positron emission tomography (PET) and nuclear magnetic resonance spectroscopy (MRS) are two biomedical measurement techniques developed in the end of the XXth century, which drastically improved the amount of accessible information available in vivo. PET ...

On the price elasticity of demand for patents

Gaétan Jean A de Rassenfosse

This paper provides an analysis of the impact of patent fees on the demand for patents. It presents a dataset of fees since 1980 at the European (EPO), the US and the Japanese patent offices. Descriptive statistics show that fees have severely decreased at ...

3D Patterning of Hydrogels and Cells by Multi-Component Inkjet Printing

Jürgen Brugger, Matthias Lütolf, Kristopher Pataky, Andrea Negro

Recapitulating the spatial and temporal complexity of tissues or organs represents one of the biggest challenges in engineering tissue-like living constructs in vitro. Inkjet printing with its high positioning precision (±1μm) and reliable droplet generati ...

Laser-Doppler flowmetry at large interoptode spacing in human tibia diaphysis: Monte Carlo simulations and preliminary experimental results

Dimitri Nestor Alice Van De Ville

Laser-Doppler flowmetry (LDF) is an outstanding tool to monitor blood flow in a continuous and non-invasive way. In this work, we study LDF at large interoptode spacing applied to a human bone model (i.e. tibia diaphysis). To that aim, we first performed a ...

A new method to measure local oxygen consumption in human skeletal muscle during dynamic exercise using near-infrared spectroscopy

Dimitri Nestor Alice Van De Ville

Near infrared spectroscopy (NIRS) can readily report on changes in blood volume and oxygenation. However, it has proved more problematic to measure real-time changes in blood flow and oxygen consumption. Here we report the development of a novel method usi ...

Studies on scaffold design for tissue engineering applications

The aim of tissue engineering is to regenerate tissue for the purpose of repairing or replacing diseased or injured tissue. Therefore, cells that are able to proliferate are seeded on scaffolds that provide mechanical stability and direct the three-dimensi ...
