Comparison of ALA- and ALA hexyl-ester-induced PpIX depth distribution in human skin carcinoma

Hubert van den Bergh, Georges Wagnières, Matthieu Philippe Emmanuel Zellweger, Tanja Gabrecht

Photodynamic therapy (PDT) based on the use of photoactivable porphyrins, such as protoporphyrin IX (PpIX), induced by the topical application of amino-levulinic acid (ALA) or its derivatives, ALA methyl-ester (m-ALA), is a treatment for superficial basal ...

Drosophila Serpin-28D regulates hemolymph phenoloxidase activity and adult pigmentation

Bruno Lemaitre

In insects the enzyme phenoloxidase (PO) catalyzes melanin deposition at the wound site and around parasitoid eggs. Its proenzyme prophenoloxidase (proPO) is proteolytically cleaved to active phenoloxidase by a cascade consisting of serine proteases and in ...

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 ...

Notch signaling via Hes1 transcription factor maintains survival of melanoblasts and melanocyte stem cells

Friedrich Beermann

Melanoblasts (Mbs) are thought to be strictly regulated by cell-cell interactions with epidermal keratinocytes, although the precise molecular mechanism of the regulation has been elusive. Notch signaling, whose activation is mediated by cell-cell interact ...

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 ...

Kernel Methods for Melanoma Recognition

Barbara Caputo, Tatiana Tommasi

Skin cancer is a spreading disease in the western world. Early detection and treatment are crucial for improving the patient survival rate. In this paper we present two algorithms for computer assisted diagnosis of melanomas. The first is the support vecto ...

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 ...

Melanocytes and pigmentation are affected in dopachrome tautomerase knockout mice

Friedrich Beermann

The tyrosinase family comprises three members, tyrosinase (Tyr), tyrosinase-related protein 1 (Tyrp1), and dopachrome tautomerase (Dct). Null mutations and deletions at the Tyr and Tyrp1 loci are known and phenotypically affect coat color due to the absenc ...

The Tyr (albino) locus of the laboratory mouse

Friedrich Beermann

The albino mouse was already known in ancient times and was apparently selectively bred in Egypt, China, and Japan. Thus, it is not surprising that the c or albino locus (now the Tyr locus) was among the first used to demonstrate Mendelian inheritance in m ...

beta-Catenin controls hair follicle morphogenesis and stem cell differentiation in the skin

beta-Catenin is an essential molecule in Wnt/wingless signaling, which controls decisive steps in embryogenesis. To study the role of beta-catenin in skin development, we introduced a conditional mutation of the gene in the epidermis and hair follicles usi ...
