Article Synopsis
- Electrical Impedance Tomography (EIT) can help measure airway opening pressure (AOP) in patients with lung issues, revealing that asymmetrical AOPs may lead to delays in air filling between the lungs.
- A study involving 23 patients, mostly with Acute Respiratory Distress Syndrome (ARDS), found that those with AOP asymmetry experienced significant delays in lung inflation compared to those with symmetrical AOPs, particularly during low-flow inflation and tidal ventilation.
- The results suggest that adjusting Positive End-Expiratory Pressure (PEEP) levels can help reduce inter-lung inflation delays, making it possible to monitor lung function effectively, even during challenging ventilation scenarios.
Article Synopsis
- The Carboniferous myriapod is the largest known arthropod, but incomplete fossils have made it hard to understand its biology and ecology.!
- Advanced imaging techniques have helped analyze well-preserved specimens from France, revealing detailed anatomical features like the head and mouthparts, and showing similarities with both millipedes and centipedes.!
- A comprehensive analysis combining morphological and genetic data positions this myriapod as a precursor to millipedes, potentially altering its evolutionary classification and highlighting the importance of integrating multiple data types in studying evolutionary relationships.!
Variations in preservation of exceptional fossils within concretions.
Swiss J Palaeontol
September 2023
Article Synopsis
- The paper explores how concretions can preserve fossils with soft tissues and emphasizes the importance of understanding fossilization methods for accurate interpretations.
- It uses probabilistic models to analyze preservation patterns in three concretionary sites: Mazon Creek (USA), Montceau-les-Mines (France), and Herefordshire (UK), focusing on the role of biological factors in fossil preservation.
- The study reveals that sites with more biological involvement show varied probabilities of finding internal organs related to other structures, enhancing understanding of preservation across different geological contexts.
In this work, early-stage Aβ42 aggregates were detected using a real-time fast amyloid seeding and translocation (RT-FAST) assay. Specifically, Aβ42 monomers were incubated in buffer solution with and without preformed Aβ42 seeds in a quartz nanopipette coated with L-DOPA. Then, formed Aβ42 aggregates were analyzed on flyby resistive pulse sensing at various incubation time points.
