'Stuck in catch-22': a qualitative study of perceived work ability and decision-making about employment in severe asthma.

Background: Severe asthma (SA) is characterised by persistent asthma symptomatology despite adherence to intensive treatment and control of asthma triggers. It is estimated that approximately 50% of individuals with SA have current employment, considerably less than rates in the general population. Poor physical and mental health status have been suggested as a potential explanation for this, but the relationship has not been investigated in depth.

Impact of global environmental changes on the range contraction of Eurasian moose since the Late Pleistocene.

Climatic oscillations are considered primary factors influencing the distribution of various life forms on Earth. Large species adapted to cold climates are particularly vulnerable to extinction due to climate changes. In our study, we investigated whether temperature increase since the Late Pleistocene and the contraction of environmental niche during the Holocene were the main factors contributing to the decreasing range of moose (Alces alces) in Europe.

Enhancing Antimicrobial Peptide Activity through Modifications of Charge, Hydrophobicity, and Structure.

Antimicrobial peptides (AMPs) are emerging as a promising alternative to traditional antibiotics due to their ability to disturb bacterial membranes and/or their intracellular processes, offering a potential solution to the growing problem of antimicrobial resistance. AMP effectiveness is governed by factors such as net charge, hydrophobicity, and the ability to form amphipathic secondary structures. When properly balanced, these characteristics enable AMPs to selectively target bacterial membranes while sparing eukaryotic cells.

A New Model and Dating for the Evolution of Complex Plastids of Red Alga Origin.

Complex plastids, characterized by more than two bounding membranes, still present an evolutionary puzzle for the traditional endosymbiotic theory. Unlike primary plastids that directly evolved from cyanobacteria, complex plastids originated from green or red algae. The Chromalveolata hypothesis proposes a single red alga endosymbiosis that involved the ancestor of all the Chromalveolata lineages: cryptophytes, haptophytes, stramenopiles, and alveolates.
