Chronological skin aging is associated with flattening of the dermal-epidermal junction (DEJ), but to date no quantitative analysis focusing on the aging changes in the dermal papillae (DP) has been performed. The aim of the study is to determine the architectural changes and the collagen density related to chronological aging in the dermal papilla zone(More)
Zinc oxide (ZnO) nanoparticles (NPs) are widely used in cosmetic and sunscreen products which are applied topically to the skin. Despite their widespread use, the safety and biological response of these particles remains an active area of investigation. In this paper we present methods based on in vivo multiphoton microscopy (MPM) in skin to address(More)
BACKGROUND Heritability of naevi counts is widely acknowledged as a potential surveillance parameter for prevention purposes. The contribution of heritability to the changes seen in naevus number and morphology over time and their corresponding dermoscopic characteristics is unknown, but is important to understand in order to account for adequate prevention(More)
The correct choice of electrodes for neurophysiologic monitoring is one of the unsolved problems in clinical practice and scientific research. In addition to the familiar electrodes, i.e., cup (silver-/silver-chloride, gold) and needle electrodes, adhesive electrodes (e.g., Zipprep electrodes) have been offered for rapid application and accurate signal(More)
The problem of electrode selection for neurophysiological monitoring, whether for routine clinical applications or special scientific research, still remains to be resolved. In addition to the classical types of electrode-cup (silver/silver chloride or gold) or needle electrodes, new self adhesive electrodes (e.g. zipprep electrodes) for rapid application(More)
