Hosts, microbiomes, and the evolution of critical windows

Evolution Letters, Volume 6, Issue 6, Page 412-425, December 2022., 2022
Abstract The absence of microbial exposure early in life leaves individuals vulnerable to immune overreaction later in life, manifesting as immunopathology, autoimmunity, or allergies. A key factor is thought to be a “critical window” during which the host's immune system can “learn” tolerance, and beyond which learning is no longer possible.

How frequently are insects wounded in the wild? A case study using Drosophila melanogaster

Royal Society Open Science
Wounding occurs across multicellular organisms. Wounds can affect host mobility and reproduction, with ecological consequences for competitive interactions and predator–prey dynamics. Wounds are also entry points for pathogens.

Monolagen‐Spezifische Struktur und Dynamik von Oberflächen‐ und Polymer‐Gestützten Lipiddoppelschichten

Angewandte Chemie, EarlyView.
Das Manuskript untersucht die strukturellen und dynamischen Eigenschaften von Polyethylenglykol‐gestützten Lipiddoppelschichten unter Verwendung einer Methode, die auf Graphen‐induziertem Energietransfer und Line‐Scan‐Fluoreszenz‐Lebenszeit‐Korrelationsspektroskopie basiert. Diese Technik ermöglicht eine subnanometer‐genaue räumliche Auflösung und eine

Limited sex differences in plastic responses suggest evolutionary conservatism of thermal reaction norms: A meta‐analysis in insects

Evolution Letters, Volume 6, Issue 6, Page 394-411, December 2022., 2022
Abstract Temperature has a profound effect on the growth and development of ectothermic animals. However, the extent to which ecologically driven selection pressures can adjust thermal plastic responses in growth schedules is not well understood. Comparing temperature‐induced plastic responses between sexes provides a promising but underexploited ...

Human Demodex Mite: The Versatile Mite of Dermatological Importance

Indian Journal of Dermatology, 2014
Demodex mite is an obligate human ecto-parasite found in or near the pilo-sebaceous units. Demodex folliculorum and Demodex brevis are two species typically found on humans. Demodex infestation usually remains asymptomatic and may have a pathogenic role only when present in high densities and also because of immune imbalance.

Selbstoptimierende Kobalt Wolframoxid Elektrokatalysatoren zur verbesserten Sauerstoffentwicklung in alkalischen Medien

Angewandte Chemie, EarlyView.
Eine schrittweise verbesserte Sauerstoffentwicklung wird durch Selbstoptimierung von Kobaltwolframoxid erreicht, das auf einem im Labor synthetisierten Kupferoxidsubstrat abgeschieden wird. Experimentelle Daten belegen eine dynamische Entwicklung der Zusammensetzung/Struktur, während theoretische Berechnungen eine Anpassung der aktiven Stelle aufzeigen.

Of Mites and Men: Johannes Kepler on Stars and Size [PDF]

arXiv, 2018
In his 1606 De Stella Nova, Johannes Kepler attempted to answer Tycho Brahe's argument that the Copernican heliocentric hypothesis required all the fixed stars to dwarf the Sun, something Brahe found to be a great drawback of that hypothesis. This paper includes a translation into English of Chapter 16 of De Stella Nova, in which Kepler discusses this ...

Biology of house dust mites and storage mites

Allergo Journal International, 2022
SummaryHouse dust mites and storage mites have a high allergenic potential and lead to sensitization through the formation of specific IgE antibodies. Due to their preferred residence in houses, they belong to the group of house mites, which are referred to as “domestic mites” in English. Their anatomy and biology account for their amazing adaptability
