The Receptor TGR5 Mediates the Prokinetic Actions of Intestinal Bile Acids and Is Required for Normal Defecation in Mice

Kristina Schoonjans

BACKGROUND & AIMS: Abnormal delivery of bile acids (BAs) to the colon as a result of disease or therapy causes constipation or diarrhea by unknown mechanisms. The G protein-coupled BA receptor TGR5 (or GPBAR1) is expressed by enteric neurons and endocrine ...

Microfluidic Droplet-Based Liquid–Liquid Extraction and On-Chip IR Spectroscopy Detection of Cocaine in Human Saliva

Nico de Rooij, Hans Peter Herzig, Lubos Hvozdara, Philip Wägli, Yu-Chi Chang

We present a portable microsystem to quantitatively detect cocaine in human saliva. In this system, we combine a microfluidic-based multiphase liquid-liquid extraction method to transfer cocaine continuously from IR-light-absorbing saliva to an IR-transpar ...

Validation of an in vitro digestive system for studying macronutrient decomposition in humans

Martinus Gijs, Guy Vergères, Flurina Schwander, Reto Portmann

The digestive process transforms nutrients and bioactive compounds contained in food to physiologically active compounds. In vitro digestion systems have proven to be powerful tools for understanding and monitoring the complex transformation processes that ...

Patterning and shaping the endoderm in vivo and in culture

Marine Marie Kraus, Anne Grapin-Botton

The definitive endoderm (DE) was first defined as the innermost germ layer found in all metazoan embryos. During development, it gives rise to a vast array of specialized epithelial cell types lining the respiratory and digestive systems, and contributes t ...

Hedgehog pathway regulators influence cervical cancer cell proliferation, survival and migration

Peter Martin Beard, Ivana Samarzija

Human papillomavirus (HPV) infection is considered to be a primary hit that causes cervical cancer. However, infection with this agent, although needed, is not sufficient for a cancer to develop. Additional cellular changes are required to complement the a ...

Droplet-based Liquid-Liquid Extraction and On-Chip IR-Waveguide-Spectroscopy Detection of Cocaine in Human Saliva

Hans Peter Herzig, Peter Van der Wal, Lubos Hvozdara, Philip Wägli, Yu-Chi Chang

We present a portable microsystem to quantitatively detect cocaine in human saliva. The chip combines a simple microfluidic method for multiphase liquid-liquid extraction to transfer cocaine from IR-light absorbing saliva to an IRtransparent solvent with t ...

Proteolysis in microfluidic droplets: an approach to interface protein separation and peptide mass spectrometry

Hubert Girault, Liang Qiao

A versatile microreactor protocol based on microfluidic droplets has been developed for on-line protein digestion. Proteins separated by liquid chromatography are fractionated in water-in-oil droplets and digested in sequence. The microfluidic reactor acts ...

Single Mode Mid-infrared Waveguide for Evanescent Sensor Scheme in Liquids

Hans Peter Herzig, Vincent Paeder, Lubos Hvozdara, Philip Wägli, Yu-Chi Chang

A Si/Ge based, single mode, mid-infrared optical waveguide, is used as an evanescent sensor in liquid matrix. The selectivity is achieved by the use of quantum cascade lasers (QCLs) tuned to the maximum absorption of a given analyte. The cocaine detection ...
