Combining visible and near-infrared images for realistic skin smoothing

Skin tone images, portraits in particular, are of tremendous importance in digital photography, but a number of factors, such as pigmentation irregularities (e.g., moles, freckles), irritation, roughness, or wrinkles can reduce their appeal. Moreover, such ...

Murine Neonatal Melanocytes Exhibit a Heightened Proliferative Response to Ultraviolet Radiation and Migrate to the Epidermal Basal Layer

Friedrich Beermann

Melanocytes respond to UVR not only by producing melanin, but also by proliferating. This is essentially a protective response. We have studied the melanocyte proliferative response after a single UVR exposure to neonatal mice. At 3 days post-UVR in wild-t ...

Surface-Functionalized Ultrasmall Superparamagnetic Nanoparticles as Magnetic Delivery Vectors for Camptothecin

Heinrich Hofmann

The linking of therapeutic drugs to ultrasmall superparamagnetic iron oxide nanoparticles (USPIOs) allowing intracellular release of the active drug via cell-specific mechanisms would achieve tumor-selective magnetically-enhanced drug delivery. To validate ...

Breast texture synthesis and estimation of the role of the anatomy and tumor shape in the radiological detection process

Cyril Castella

Breast cancer is the most common, and the number one cause of death by cancer among women. However, when it is sufficiently early detected, heavy treatments can be avoided, and morbidity and mortality can be reduced. This is the reason why randomized clini ...

Asymmetric distribution of epidermal growth factor receptor directs the fate of normal and cancer keratinocytes in vitro

Nathan Quentin Faivre

Cancer cells are unequal in a tumor mass and in established cultures. This is attributable to cancer stem cells with the unique ability to self-renew and to generate differentiating progeny. This ability is controlled at the level of asymmetric division by ...

Mathematical modeling of the re-epithelialization of a 3 dimensional (3d) human skin equivalent

Raphaelle Luisier

Re-epithelialization is the dominant mode of healing in partial thickness wounds. In order to develop better strategies to monitor such wound healing, 3D HSE models and mathematical models have long been utilized to improve our understanding of epidermis f ...

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 ...

Pten deficiency in melanocytes results in resistance to hair graying and susceptibility to carcinogen-induced melanomagenesis

Friedrich Beermann

Phosphate and tensin homologue deleted on chromosome 10 (PTEN) is a tumor suppressor gene inactivated in numerous sporadic cancers, including melanomas. To analyze Pten functions in melanocytes, we used the Cre-loxP system to delete Pten specifically in mu ...

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. ...
