Insulin secretion from vesicles within pancreatic beta cells occurs through the rapid (≤10 ms) process of exocytosis. A crucial final step in this process is the formation of a fusion pore, which connects the insulin vesicle interior to the extracellular space and insulin secretion rate. We employed real-time single-cell amperometry (SCA) with microsensors to quantitatively and dynamically monitor

In this chapter, we describe the work involved in developing a pedagogical framework at Lund University (LU). The work was carried out as a project. In our roles as educational developer and project manager for educational activities, we accepted an assignment to create a new framework that values pedagogical expertise.We collaborated with appointment committees, pedagogical units, representatives

The transformation in the purposes, instruments, and conditions for the deployment of coercion was a central aspect of the modernization of Western European states during the long nineteenth century. Nowhere is this transformation as evident as in the emergence and diffusion of public, specialized, and professional police forces at the time. In this article, we employ automated text analysis to ex

Photocatalysis plays a crucial role in harnessing renewable energy by efficiently converting solar energy into chemical energy. Adequate cognition of photogenerated charge carrier dynamics in photocatalysis is the key to realizing efficient solar energy utilization, and provides guidance for breaking through the efficiency bottleneck. However, a convincing correlation between those photophysical p

Syndromic testing for lower respiratory tract infections with BioFire® FilmArray® Pneumonia Panel Plus (BF) detects 27 pathogens with a turn-around-time of one hour. We compared the performance of BF with culture. Samples from 298 hospitalized patients with suspected pneumonia routinely sent for culture were also analyzed using BF. Retrospectively, patients were clinically categorized as having "p

Chirality is omnipresent in the living world. As biomimetic nanotechnology and self-assembly advance, they too need chirality. Accordingly, there is a pressing need to develop general methods to characterize chiral building blocks at the nanoscale in liquids such as water─the medium of life. Here, we demonstrate the chiroptical second-harmonic Tyndall scattering effect. The effect was observed in

The active manipulation of particle and cell trajectories in fluids by high-frequency standing surface acoustic waves (sSAW) allows to separate particles and cells systematically depending on their size and acoustic contrast. However, process technologies and biomedical applications usually operate with non-spherical particles, for which the prediction of acoustic forces is highly challenging and

Enzyme regulation is vital for metabolic adaptability in living systems. Fine control of enzyme activity is often delivered through post-translational mechanisms, such as allostery or allokairy. β-phosphoglucomutase (βPGM) from Lactococcus lactis is a phosphoryl transfer enzyme required for complete catabolism of trehalose and maltose, through the isomerisation of β-glucose 1-phosphate to glucose

Standards are put forward as important means to turn the ideals of ethical and responsible artificial intelligence into practice. One principle targeted for standardization is transparency. This article attends to the tension between standardization and transparency, by combining a theoretical exploration of these concepts with an empirical analysis of standardizations of artificial intelligence t
