Optical Investigation of Skin Morphology and Anatomy

Theo Lasser, Rainer Leitgeb, Roland Michaely

This project investigates skin anatomy and physiology by three optical, non-invasive techniques: Fringe projection topography mainly for the investigation of tissue topography Parallel laser Doppler blood flow imaging for the investigation of tissue micro ...

Phase manipulation without phase shifter for complex FDOCT signal reconstruction and resonant Doppler imaging

Theo Lasser, Rainer Leitgeb, Martin Villiger, Adrian Bachmann, Roland Michaely, Cédric Blatter

We demonstrate a simple and cheap method for phase shifting that does not need additional devices. A small beam offset at the fast scanning mirror introduces a causal phase shift which can be used for recently introduced B-scan based complex image reconstr ...

Influence of process pressure on local facesheet instability for ultralight sandwich structures

Yves Leterrier, Julien Rion, Samuel Stutz

The skin wrinkling phenomenon was investigated in case of ultralight sandwich structures with honeycomb core manufactured by one shot vacuum bag processing. A relation between process pressure and compressive strength of the skin was established. ...

Effect of wellbore storage and finite thickness skin on flow to a partially penetrating well in a phreatic aquifer

David Andrew Barry

An analytical model is presented for the analysis of constant flux tests conducted in a phreatic aquifer having a partially penetrating well with a finite thickness skin. The solution is derived in the Laplace transform domain for the drawdown in the pumpi ...

Complex ambiguity-free Fourier domain optical coherence tomography through transverse scanning

Theo Lasser, Rainer Leitgeb, Roland Michaely

We introduce a simple and cheap method for phase-shifting Fourier domain optical coherence tomography (FDOCT) that does not need additional devices and can easily be implemented. A small beam offset at the fast beam-scanning mirror introduces a causal phas ...

Direct load transmission in hybrid FRP and lightweight concrete sandwich bridge deck

Thomas Keller, Till Vallée, Erika Schaumann

Direct load transmission experiments on hybrid short-span beam specimens for a novel bridge deck were performed. The sandwich construction consists of three layers: a fiber- reinforced polymer composite (FRP) sheet with T-upstands for the bottom skin, ligh ...

Understanding engraftment of cultured epidermal stem cells

Nicolas Grasset

The epidermis and its appendages protect our body from environmental hazards. Cells generated in the basal layer continuously replace the terminally differentiated keratinocytes that are shed off the epidermal surface. Long-term renewal depends on specific ...

Epithelial stem cells and mechanical signal transduction

Vincent Bernard Cattin

Hair follicles are cutaneous structures characteristic of mammals. These sensitive organs cycle and contain multipotent epithelial stem cells which are implicated in hair growth and hair cycle. A single whisker follicle of the rat hosts up to 1500 stem cel ...

The role of actively released fibrin-conjugated VEGF for VEGF receptor 2 gene activation and the enhancement of angiogenesis

Jeffrey Alan Hubbell, Martin Ehrbar

A major challenge for therapeutic delivery of angiogenic agents such as vascular endothelial growth factor (VEGF) is to achieve sustained, low dose signaling leading to durable neovessel formation. To this end, we recently created a variant of VEGF(121), T ...

Dependence of reversibility and progression of mouse neuronopathic Gaucher disease on acid beta-glucosidase residual activity levels

Genetic and chemically induced neuronopathic mouse models of Gaucher disease were developed to facilitate understanding of the reversibility and/or progression of CNS involvement. The lethality of the skin permeability barrier defect of the complete gene k ...
