Neue Laser und Strahlquellen – alte und neue Risiken?

Abstract

In diesem Szenario ist es wichtig, alle potenziellen Anwender dieser neuen Technologien vor deren Einsatz so zu qualifizieren, dass den Therapierten maximale Therapiesicherheit bei höchster Effizienz unter dem Leitbild diagnosis certa -ullae therapiae fundamentum garantiert wird. SummaryRecent developments (new wavelengths, treatment concepts, and combinations) in the field of lasers, intense pulsed light (IPL), LED, as well as new energy and light sources have opened up new therapeutic options that extend beyond mere aesthetic indications. Thus, while fractional lasers used to be employed to merely treat wrinkles, the same devices -in the context of laser-assisted drug delivery -have now become important tools in the treatment of scars, field cancerization, and epithelial tumors.

Novel Widespread Marine Oomycetes Parasitising Diatoms, Including the Toxic Genus Pseudo-nitzschia: Genetic, Morphological, and Ecological Characterisation

“…Mapping observed OOM_1 and Miracula helgolandica (Buaya et al, 2017) and OOM_2 and Olpidiopsis drebesii (Buaya et al, 2017) life stages against Pseudo-nitzschia pungens oomycete parasitoid life cycle (Hanic et al, 2009) and the defining morphological criteria for the Ectrogella genus (Zopf, 1884; Scherffel, 1925). The development cycle of the oomycete parasitoid of P. pungens described by Hanic et al (2009) is reproduced in the inner ellipse.…”

“…Among all known holocarpic pathogens of diatoms, OOM_1 and OOM_2 are clearly distinct from Lagenisma coscinodisci , both morphologically and molecularly (Thines et al, 2015). Aphanomycopsis bacillariacearum and Lagenidium enecans are two lesser known parasitoids of diatoms that still remain to be characterised molecularly (Scherffel, 1925). However, the combined absence in our observations of branched sporangium, persistent infection tube, elongated DT, primary spore encysting at the mouth of the DT, and of thick-walled resting spore make an affiliation of OOM_1 or OOM_2 to either of these taxa most unlikely.…”

“…on the basis of an intramatrical, unbranched and holocarpic thallus, producing uniflagellate, diplanetic spores (Zopf, 1884). Scherffel subsequently gave a conflicting account of spore flagellation and generations (Scherffel, 1925). These initial descriptions were followed by numerous, sometimes patchy, observations that have aggregated more criteria, such as the presence of sexual reproduction or resting spores.…”
