iPSC-Derived Epithelial, Mesenchymal, Endothelial, and Immune Cell Co-Culture to Model Airway Barrier Integrity in Lung Health and Disease.

Human lung tissue is composed of an interconnected network of epithelium, mesenchyme, endothelium, and immune cells from the upper airway of the nasopharynx to the smallest alveolar sac. Interactions between these cells are crucial in lung development and disease, acting as a barrier against harmful chemicals and pathogens. Current in vitro co-culture models utilize immortalized cell lines with different biological backgrounds, which may not accurately represent the cellular milieu or interactions of the lung.

In vivo treatment with a non-aromatizable androgen rapidly alters the ovarian transcriptome of previtellogenic secondary growth coho salmon (Onchorhynchus kisutch).

Recent evidence suggests that androgens are a potent driver of growth during late the primary stage of ovarian follicle development in teleosts. We have previously shown that the non-aromatizable androgen, 11-ketotestosterone (11-KT), both advances ovarian follicle growth in vivo and dramatically alters the primary growth ovarian transcriptome in coho salmon. Many of the transcriptomic changes pointed towards 11-KT driving process associated with the transition to a secondary growth phenotype.

Several common methods of making vesicles (except an emulsion method) capture intended lipid ratios.

Unlabelled: Researchers choose different methods of making giant unilamellar vesicles in order to satisfy different constraints of their experimental designs. A challenge of using a variety of methods is that each may produce vesicles of different lipid compositions, even if all vesicles are made from a common stock mixture. Here, we use mass spectrometry to investigate ratios of lipids in vesicles made by five common methods: electroformation on indium tin oxide slides, electroformation on platinum wires, gentle hydration, emulsion transfer, and extrusion.

Digital Health Applications (DiHA): Approaches to develop a reimbursement process for the statutory health insurance in Austria.

Purpose: To elaborate a concept for implementing digital health applications (DiHA), including prioritisation criteria (PC) for the Austrian context and an overview of available prioritised DiHAs.

Methods: Based on European DiHA-listings and input by Austrian experts, a categorised meta-directory of DiHAs was created. PC were developed to reflect, inter alia, the provisions of the Austrian General Insurance Act, and were applied to the meta-directory to identify DiHAs potentially relevant for the Austrian statutory health insurance.
