Im Rahmen der vorliegenden Arbeit wurden selbstassemblierte Monolagen organischer Moleküle an der Fest-Flüssig-Grenzfläche von Graphit mittels Rastertunnelmikroskopie untersucht. Die Arbeit verfolgte das Ziel, das Verständnis ......
Contribution of resident macrophages to the fetal liver hematopoietic stem cell niche
(2022-07-29)
Tissue-resident macrophages are a heterogeneous population of phagocytes found in almost all tissues of the body. Recent studies indicate that most resident macrophages originate from yolk sac progenitors and are maintained ...
Enhanced skin permeation of small molecules via retention of enhancer substances in matrix-type transdermal patches
(2022-08-29)
A long-standing approach to improve the transdermal drug permeation is to use chemical penetration enhancers. Those substances reduce the barrier properties of the skin, especially of the stratum corneum, and facilitate ...
Topics in Population Imaging: The Rhineland Study
(2022-07-29)
Population imaging is the large-scale data acquisition and analysis of medical images in population-based cohorts. When combined with other data acquired in the cohort, it provides the unique potential to characterise ...
