Unified Simulation Platform for Interference Microscopy.

Interferometric scattering microscopy is a powerful technique that enables various applications, such as mass photometry and particle tracking. Here, we present a numerical toolbox to simulate images obtained in interferometric scattering, coherent bright-field, and dark-field microscopies. The scattered fields are calculated using a boundary element method, facilitating the simulation of arbitrary sample geometries and substrate layer structures.

Conversion of anterograde into retrograde trains is an intrinsic property of intraflagellar transport.

Cilia or eukaryotic flagella are microtubule-based organelles found across the eukaryotic tree of life. Their very high aspect ratio and crowded interior are unfavorable to diffusive transport of most components required for their assembly and maintenance. Instead, a system of intraflagellar transport (IFT) trains moves cargo rapidly up and down the cilium (Figure 1A).

Confocal Laser Scanning Microscopy-Based Quantitative Analysis of Aspergillus fumigatus Conidia Distribution in Whole-Mount Optically Cleared Mouse Lung.

Aspergillus fumigatus conidia are airborne pathogens that can penetrate human airways. Immunocompetent people without allergies exhibit resistance and immunological tolerance, while in immunocompromised patients, conidia can colonize airways and cause severe invasive respiratory disorders. Various cells in different airway compartments are involved in the immune response that prevents fungal invasion; however, the spatio-temporal aspects of pathogen elimination are still not completely understood.

Efficacy of mecillinam against clinical multidrug-resistant Escherichia coli in a murine urinary tract infection model.

Pivmecillinam, a pro-drug of mecillinam, has been used extensively in Scandinavia for the treatment of acute lower urinary tract infections (UTIs) caused by Enterobacterales. It is still an attractive first-line drug for the empirical treatment of UTIs owing to the low prevalence of resistance as well as its favourable impact on the intestinal microbiota as a pro-drug and good in vitro efficacy against extended-spectrum β-lactamase (ESBL)- and plasmid-mediated AmpC β-lactamase-producing Escherichia coli. However, optimal dosing of pivmecillinam as well as its in vivo efficacy against UTIs caused by multidrug-resistant (MDR) broad-spectrum β-lactamase-producing E.
