Advanced process of the magnetic core integration for the micro fluxgate magnetometer

Radivoje Popovic, Pavel Kejik, Franck Vincent, Predrag Drljaca

We present improved processing of the soft amorphous ferromagnetic material for the fully integrated fluxgate magnetometer. The additional steps of polishing, chemical thinning and annealing are introduced to preserve the original material characteristics ...

Full-field high-speed laser Doppler imaging system for blood-flow measurements

Theo Lasser

We describe the design and performance of a new full-field high-speed laser Doppler imaging system developed for mapping and monitoring of blood flow in biological tissue. The total imaging time for 256x256 pixels region of interest is 1.2 seconds. An inte ...

Melanoma Recognition using Kernel Classifiers

Barbara Caputo, Tatiana Tommasi

Melanoma is the most deadly skin cancer. Early diagnosis is a current challenge for clinicians. Current algorithms for skin lesions classification focus mostly on segmentation and feature extraction. This paper instead puts the emphasis on the learning pro ...

Neural crest-derived cells with stem cell features can be traced back to multiple lineages in the adult skin

Yann Barrandon, Friedrich Beermann, Ariane Rochat, Lukas Sommer

Given their accessibility, multipotent skin-derived cells might be useful for future cell replacement therapies. We describe the isolation of multipotent stem cell-like cells from the adult trunk skin of mice and humans that express the neural crest stem c ...

Full-field laser Doppler perfusion imaging and monitoring with an intelligent CMOS camera

Theo Lasser

A system for full-field laser Doppler blood flow imaging has been developed and tested on biomedical samples. The new imaging system allows 2D flow maps or monitoring flux signals to be obtained from a plurality of measured points simultaneously by using a ...

High-speed laser Doppler perfusion imaging using an integrating CMOS image sensor

Theo Lasser

This paper describes the design and the performance of a new high-speed laser Doppler imaging system for monitoring blood flow over an area of tissue. The new imager delivers high-resolution flow images (256 x 256 pixels) every 2 to 10 seconds, depending o ...

Notch1 is essential for postnatal hair follicle development and homeostasis

Freddy Radtke, Yann Barrandon

Notch genes encode evolutionarily conserved large, single transmembrane receptors, which regulate many cell fate decisions and differentiation processes during fetal and postnatal life. Multiple Notch receptors and ligands are expressed in both developing ...

Effect of microcapsule composition and short-term immunosuppression on intraportal biocompatibility

Jutta Christine Wandrey, David Hunkeler, Dianelys Sainz Vidal

With higher nutrient and oxygen supply and close contact to blood, the portal vein is a possible alternative to the peritoneal cavity for transplantation of encapsulated cells. Data regarding intraportal biocompatibility of microcapsules are lacking. Micro ...

Stress suppresses and learning induces plasticity in CA3 of rat hippocampus: a three-dimensional ultrastructural study of thorny excrescences and their postsynaptic densities

Maria del Carmen Sandi Perez, Maria Isabel Cordero Campana

Chronic stress and spatial training have been proposed to affect hippocampal structure and function in opposite ways. Previous morphological studies that addressed structural changes after chronic restraint stress and spatial training were based on two-dim ...

More than just proliferation: Myc function in stem cells

Anne Wilson

Adult stem cells are essential to maintain regenerative tissues such as skin epidermis, gastrointestinal mucosa or the hematopoietic system. Recent studies in mice suggest that the transcription factor and oncoprotein c-Myc has unexpected functions during ...
