Background: Amidst the difficulty and contentiousness of improving hospitals, a relatively new approach is the Relational Model of Organizational Change (RMOC). However, this approach has its own challenges, including reports that its focus on communication and relationships is undervalued despite evidence supporting its use to facilitate practice improvements in hospitals. Research suggests power dynamics in hospitals influences how the RMOC is used, but the precise mechanisms through which this occurs have not been fully examined.

Here we report the in vivo mapping of connections between presynaptic and postsynaptic partners in zebrafish, by adapting the trans-Tango genetic approach that was first developed for anterograde transsynaptic tracing in Drosophila. Neural connections were visualized between synaptic partners in larval retina, brain and spinal cord and followed over development.

- The study aimed to improve the efficiency of measuring neurotransmitter metabolites (5-HIAA, VMA, and HVA) in urine, which are crucial for diagnosing neuroendocrine tumors, through automation.
- The method involved using automated supported liquid extraction (SLE) combined with liquid chromatography tandem mass spectrometry (LC-MS/MS) for accurate measurement and analysis of these metabolites.
- Results showed high recovery rates and successful validation across various performance criteria, with automation leading to significant time savings in the process.
In Batesian mimicry, mimetic traits are not always as convincing as predicted by theory-in fact, inaccurate mimicry with only a superficial model resemblance is common and taxonomically widespread. The "selection trade-offs hypothesis" proposes a life-history trade-off between accurate mimetic traits and one or more vital biological functions. Here, using an accurate myrmecomorphic (ant-mimicking) jumping spider species, Myrmarachne smaragdina, we investigate how myrmecomorphic modifications to the body shape impact the internal anatomy in a way that could be functionally limiting.

The purpose of this study was to determine the rate of PJK in patients with AIS who had a UIV of T1 vs those with a UIV of T2 at 5 years of follow-up.
Methods: A query was performed of a prospective, multi-center AIS database of patients who received a PSF with at least 5 years of follow-up.
