Degradation study on molecules released from laser-based jet injector

Christophe Moser, Jan Krizek, Barbora Lavickova

Development of needle-free methods to administer injectable therapeutics has been researched for a few decades. We focused our attention on a laser-based jet injection technique where the liquid-jet actuation mechanism is based on optical cavitation. This ...

Characterization of circulating breast cancer cells with tumorigenic and metastatic capacity

Cathrin Brisken, Georgios Sflomos, Laura Battista

Functional studies giving insight into the biology of circulating tumor cells (CTCs) remain scarce due to the low frequency ofCTCs and lack of appropriate models. Here, we describe the characterization of a novelCTC-derived breast cancer cell line, designa ...

Toward Microfluidic Label-Free Isolation and Enumeration of Circulating Tumor Cells from Blood Samples

Philippe Renaud, Margaux Catherine Marie Duchamp, Camille Alice Raillon, Benoît Xavier Emmanuel Desbiolles

The isolation, analysis, and enumeration of circulating tumor cells (CTCs) from cancer patient blood samples are a paradigm shift for cancer patient diagnosis, prognosis, and treatment monitoring. Most methods used to isolate and enumerate these target cel ...

A biosensor for measuring NAD(+) levels at the point of care

Johan Auwerx, Kai Johnsson, Luc Patiny, Elena Katsyuba, Qiuliyang Yu, Lin Xue

The cellular level of nicotinamide adenine dinucleotide (NAD(+)), through its different functions, affects cellular metabolism and signalling(1-3). A decrease in the NAD(+) content has been associated with various pathologies and physiological aging(4,5), ...

Microdevice-integrated immunoassays for Point-of-Care Therapeutic Drug Monitoring

Elena-Diana Bojescu

A significant number of drugs exhibit narrow therapeutic windows and high inter-individual pharmacokinetic variability. In such cases, Therapeutic Drug Monitoring (TDM) is compulsory in order to optimize the efficacy of the drug while avoiding adverse effe ...

Sensitive and fast identification of bacteria in blood samples by immunoaffinity mass spectrometry for quick BSI diagnosis

Hubert Girault, Horst Pick, Niels Erik Lion, Natalia Gasilova, Michel Prudent, Liang Qiao, Yingdi Zhu, Alexandra Bondarenko

Bloodstream infections rank among the most serious causes of morbidity and mortality in hospitalized patients, partly due to the long period (up to one week) required for clinical diagnosis. In this work, we have developed a sensitive method to quickly and ...

Image-Derived Input Function from the Vena Cava for 18F-FDG PET Studies in Rats and Mice

Rolf Gruetter, Bernard Lanz, Carole Poitry-Yamate

Measurement of arterial input function is a restrictive aspect for quantitative 18F-FDG PET studies in rodents because of their small total blood volume and the related difficulties in withdrawing blood. METHODS: In the present study, we took advantage of ...
