Data from: Aldosterone reduction rate after saline infusion may be a novel clinical prediction of determining subtypes of primary aldosteronism
<p><span><span><span><span><span><span><span><span><span><span><span><b>Objective</b>Accurate assessment of the localization of aldosterone-producing adenomas (APAs) is essential for the treatment of primary aldosteronism (PA). Although adrenal venous sampling (AVS) is the standard method of reference for subtype diagnosis in PA, controversy exists concerning the criteria for interpretation. This study aimed to determine better indicators that can reliably predict subtypes of PA. </span></span></span></span></span></span></span></span></span></span></span></p> <p><span><span><span><span><span><span><span><span><span><span><span><b>Method</b>Retrospective analysis in single-cohort including 209 patients with PA who were subjected to AVS. 82 patients whose plasma aldosterone concentrations (PAC) were normalized after surgery were histopathologically or genetically diagnosed with APA. The accuracy of image findings was compared to AVS results. Receiver operating characteristic (ROC) curve analysis between the operated and no apparent laterality groups was performed using AVS parameters and loading test for diagnosis of PA. </span></span></span></span></span></span></span></span></span></span></span></p> <p><span><span><span><span><span><span><span><span><span><span><span><b>Result </b>The agreement between image findings and AVS results was 56.3%. ROC curve analysis revealed that lateralization index (LI) after ACTH stimulation cutoff value was 2.40, with 98.8% sensitivity and 97.1% specificity. The contralateral suppression index (CSI) cutoff value was 1.19, with 98.0% sensitivity and 93.9% specificity. All patients over the LI and CSI cutoff values exhibited unilateral subtypes. Among the loading test, <span><span>the best classification accuracy was achieved using the </span></span>PAC reduction rate after saline infusion<span><span>test (SIT) >33.8%, which yielded 87.2% sensitivity or PAC after SIT <87.9 pg/mL 86.2% specificity for predicting bilateral PA. </span></span></span></span></span></span></span></span></span></span></span></span></span></p> <p><span><span><span><span><span><span><span><span><span><span><span><b>Conclusion</b>The combined criterion of the PAC reduction rate and PAC after SIT may determine a subset of patients with APA who should be performed AVS for validation. </span></span></span></span></span></span></span></span></span></span></span></p> <p><br> </p>

Data from: Phylogenetic signal detection from an ancient rapid radiation: effects of noise reduction, long-branch attraction, and model selection in crown clade Apocynaceae
Crown clade Apocynaceae comprise seven primary lineages of lianas, shrubs, and herbs with a diversity of pollen aggregation morphologies including monads, tetrads, and pollinia, making them an ideal group for investigating the evolution and function of pollen packaging. Traditional molecular systematic approaches utilizing small amounts of sequence data have failed to resolve relationships along the spine of the crown clade, a likely ancient rapid radiation. The previous best estimate of the phylogeny was a five-way polytomy, leaving ambiguous the homology of aggregated pollen in two major lineages, the Periplocoideae, which possess pollen tetrads, and the milkweeds (Secamonoideae plus Asclepiadoideae), which possess pollinia. To assess whether greatly increased character sampling would resolve these relationships, a plastome sequence data matrix was assembled for 13 taxa of Apocynaceae, including nine newly generated complete plastomes, one partial new plastome, and three previously reported plastomes, collectively representing all primary crown clade lineages and outgroups. The effects of phylogenetic noise, long-branch attraction, and model selection (linked versus unlinked branch lengths among data partitions) were evaluated in a hypothesis-testing framework based on Shimodaira–Hasegawa tests. Discrimination among alternative crown clade resolutions was affected by all three factors. Exclusion of the noisiest alignment positions and topologies influenced by long-branch attraction resulted in a trichotomy along the spine of the crown clade consisting of Rhabdadenia + the Asian clade, Baisseeae + milkweeds, and Periplocoideae + the New World clade. Parsimony reconstruction on all optimal topologies after noise exclusion unambiguously supports parallel evolution of aggregated pollen in Periplocoideae (tetrads) and milkweeds (pollinia). Our phylogenomic approach has greatly advanced the resolution of one of the most perplexing radiations in Apocynaceae, providing the basis for study of convergent floral morphologies and their adaptive value.
Python notebooks as a pedagogical tool to teach NOT data reduction
<p>We will present a series of seven Python Jupyter Notebooks designed to teach master-level students the basic steps of data reduction for observations with the Alhambra Faint Object Spectrograph and Camera (ALFOSC). This pedagogical tool, which translates IRAF tasks into the widespread Python language, has been successfully deployed for the course “Observational Astrophysics II” at the Department of Astronomy of Stockholm University. Each notebook introduces the students to one specific task of the data reduction explaining the purpose of that task, how it is implemented and guiding the students through the completion of the task. With a hands-on approach, this allows the students to understand the reason behind each step and to test directly what is the effect of each step, thanks to interactive plots of the data and the intermediate products. In addition to its educational value, this material can be expanded to reach the quality needed for scientific works. Therefore it could offer a starting point for developing a personalised data reduction for a given scientific problem. A complete version of the material is publicly available at https://github.com/astrojuggler/data-reduction-Obs-II-course. This project has been financed by Stockholm University - Department of Astronomy with a grant earned by Professor Matthew Hayes.</p>

Data for the paper, Origin of copper dissolution in electrocatalytic reduction conditions involving amines
<p>This dataset supports the paper titled "Origin of copper dissolution in electrocatalytic reduction conditions involving amines" The study aims to elucidate the atomic-scale mechanism of copper (Cu) dissolution under electrochemical conditions, particularly in the presence of acetone and methylamine mixtures, and under reductive potential conditions (-0.75V vs RHE). </p> <p><strong>Usage:</strong> This dataset is valuable for researchers focusing on electrochemical amination, cathode degradation processes, and the design of durable Cu-based cathodes. The insights from the GC-DFT calculations provide a fundamental understanding of Cu dissolution facilitated by surface restructuring in amine solutions under electroreduction conditions. The data can be used to further explore the mechanisms of Cu electrode corrosion and to design more stable and efficient electrochemical systems involving amines.</p>
