DFT-NMR-Validated Full Structure Elucidation of Theionbrunonine C, An Unstable N-Oxide Theionbrunonine from Mostuea brunonis
<p>The structure elucidation of theionbrunonine C, a thioether-bridged dimeric monoterpene indole alkaloid (MIA), and more generally, one of the very few Sulfur-containing MIA, is reported after its isolation from Mostuea brunonis (Gelsemiaceae). This unstable structure had already been targeted for isolation in our former, molecular network-guided, investigation of this plant but this compound had degraded before sufficient spectroscopic data could have been acquired for a complete structure assignment. With this constraint in mind, the rapid acquisition of NMR data enabled retrieving sufficient spectroscopic information for full structure elucidation, although from a partial set of spectroscopic information (1H and 13C NMR; COSY, HSQC, and HMBC). In conjunction with biosynthetic considerations, the cursory examination of 13C NMR data unambiguously defined the complete stereostructure of 1, as further supported by DFT-NMR calculations and subsequent DP4 probability score.</p>

Data from: Validity, applicability and universality of fractal scaling laws for natural lakes
<p><span>We conducted a systematic investigation on the validity, applicability and universality of the fractal scaling relationships for natural lakes within China. Hydro-climatic zones from the Hydrological regionalization of China were taken as the statistical units for all the analyses. Lake size and hydrological parameters used in the analyses are from the HydroLAKES database. To test the validity of the fractal scaling relationships between lake properties, power law functions were fitted to these properties. To examine the effects of topographical relief on the power law size distribution, regional degree of topographical relief was calculated for each zone based on ASTER GDEM2. To explore the potential impacts of human activities on the applicability of power law size distribution, Human modification index data was jointly analyzed with the power law distribution of lake size.</span></p>

Supplemental material for: Validation of intraluminal filling defect length to identify carotid free-floating thrombus in patients with stroke/TIA
<p><strong>Objective: </strong>To validate a previously proposed filling defect length threshold of >3.8 mm on CT-angiography (CTA) to discriminate between free-floating thrombus (FFT) and plaque of atheroma.</p> <p><b>Materials and Methods: </b>Prospective multicenter observational study of 100 participants presenting with TIA/stroke symptoms and a carotid intraluminal filling defect on initial CTA. Follow-up CTA was obtained within one week, and at weeks 2 and 4 if the intraluminal filling defect was unchanged in length. Resolution or decreased length was diagnostic of FFT, whereas its static appearance after 4 weeks was indicative of plaque. Diagnostic accuracy of FFT length was assessed by receiver operating characteristic analysis.</p> <p><b>Results: </b>Ninety-five participants (mean age [standard deviation], 68 [13] years; 61 men; 83 participants with FFT; 12 participants with a plaque) were evaluated. The >3.8 mm threshold had a sensitivity of 88% (73/83) (95% confidence interval {CI}: 78%, 94%) and specificity of 83% (10/12) (95% CI, 51%, 97%) (area under the curve [AUC], 0.91, p<.001) for the diagnosis of FFT. The optimal length threshold was >3.64 mm with a sensitivity of 89%( 74/83) (95% CI, 80%, 95%) and specificity of 83% (10/12) (95% CI, 51%, 97%). Adjusted logistic regression showed that every 1 mm increase in intraluminal filling defect length is associated with an increase in odds of FFT of 4.6 ([95% CI] 1.9-11.1; <i>p</i>=.01).</p> <p><b>Conclusion: </b>CTA enables accurate differentiation of FFT versus plaque using craniocaudal length thresholds.</p> <p><strong>Clinical Trial Identifier:</strong> <a href="http://www.clinicaltrials.gov">www.clinicaltrials.gov</a> NCT02405845.</p> <p><b>Classification of Evidence: </b>This study provides Class I evidence that in patients with TIA/stroke symptoms, the presence of a carotid intraluminal filling defect with length > 3.8 mm on CTA accurately discriminates free-floating thrombus from atheromatous plaque.</p>

Computational validation of clonal and subclonal copy number alterations from bulk tumour sequencing
<p>Somatic variant identification from WGS data is a crucial step in the analysis of cancer genomes. Several tools are available to perform mutations calling, however, the noisiness of data requires appropriate quality control assessment. In the preprint work available at https://doi.org/10.1101/2021.02.13.429885 we present CNAqc, an R package devised to assess the quality of allele-specific Copy Number Alterations (CNA), somatic mutations, and tumor purity estimates. In order to test the model, we ran CNAqc on 2778 single-sample PCAWG whole-genomes and 48 TCGA whole-exomes. We uploaded the results of our analysis using the release of the tool available at https://github.com/caravagnalab/CNAqc/releases/tag/rr_22_0.1 in the form of .rds files. All the necessary details for the reproduction of our results are reported in the Supplementary Materials of the above-mentioned manuscript.</p>

Validating the use of stereo-video cameras to conduct remote measurements of sea turtles
<p>Stereo-Video Camera Systems (SVCSs) are a promising tool to remotely measure body size of wild animals without the need for animal handling. Here, we assessed the accuracy of SVCSs for measuring straight carapace length (SCL) of sea turtles. To achieve this, we hand captured and measured 63 juvenile, sub-adult, and adult sea turtles across three species, greens, <i>Chelonia mydas </i>(n = 52), loggerheads, <i>Caretta caretta </i>(n = 8), and<i> </i>Kemp's ridley, <i>Lepidochelys kempii </i>(n = 3) in the waters off Eleuthera, The Bahamas and Crystal River, Florida, U.S.A. between May - November 2019. Upon release, we filmed these individuals with the SVCS. We performed photogrammetric analysis to extract stereo SCL measurements (eSCL), which were then compared to the (manual) capture measurements (mSCL). mSCL ranged from 25.9 – 89.2 cm, while eSCL ranged from 24.7 – 91.4 cm. Mean percent bias of eSCL ranged from -0.61% (± 0.11 SE) to -4.46% (± 0.31 SE) across all species and locations. We statistically analyzed potential drivers of measurement error, including distance of the turtle to the SVCS, turtle angle, image quality, turtle size, capture location, and species.Using a linear mixed effects model, we found that the distance between the turtle and the SVCS was the primary factor influencing measurement error. Our research suggests that stereo-video technology enables high-quality measurements of sea turtle body size collected <i>in situ</i> without the need for hand-capturing individuals. This study contributes to the growing knowledge base that SVCS are accurate for body size measurements independent of taxonomic clade.</p>

Development and validation of a Community Resilience Scale for Youth (CRS-Y) Community Resilience Scale for Regional Youth
<p>The purpose of this article is to present the development and validation of a Community Resilience Scale for Youth (CRS-Y) among a Portuguese sample of nearly 4000 young people growing up in regions on the border with Spain. The scale was developed for young people to assess their perception of the resilience of regional communities in terms of positive development and purposeful experiences for young people. Resilient communities, under a social ecological approach, are those able to move forward on social change and transformation. This concept is especially remarkable in more challenging contexts such as border regions of mainland Portugal which are characterised by economic, social, educational, and cultural disadvantages while discovering possibilities of resilience through promising local dynamics.</p> <p>A multi-step approach was used to develop this scale of 12-item scale. Items were generated based on an in-depth literature review and research previously conducted with young people in these contexts. The overall sample was randomly divided into two subsamples of 1828 and 1735 young people each. Principal component analysis was performed with one of the subsamples and yielded a three-factor structure, explaining 61.5% of the total variance. Confirmatory factor analysis performed on the second showed good fit indexes. Furthermore, internal consistency of the three proposed components, gauged either by Cronbach’s alpha or McDonald’s omega, indicated good reliability. Given the results, the CRS-Y is a valid and reliable tool showing adequate psychometric properties.</p> <p>This scale will be useful for schools and policy makers at the local level. Indicators such as the promotion of opportunities to participate and be recognised, collective trust and the promotion of shared values and protection are relevant in assessing regional communities’ resilience and informing youth policies.</p> <p> </p> <p><strong>The scoring and interpretation guidelines for this scale should be as follows:</strong></p> <p>The Community Resilience Scale for Youth (CRS-Y) was developed for young people to assess their perception of the resilience of regional communities in terms of positive development and purposeful experiences for young people. The scale consists of 12 items rated on a 5-point Likert scale (1=low agreement to 5=high agreement), where participants indicate their level of agreement with each statement about their community. </p> <p>Items are grouped into a total score [MEAN(Factor1,Factor2,Factor3)] and three factors/dimensions: </p> <p>Factor 1-Promotion of opportunities and collective trust [5 items; MEAN(Item1,Item2,Item3,Item4,Item5)];</p> <p>Factor 2-Promotion of shared values and protection [4 items; MEAN(Item6,Item7,Item8,Item9)];</p> <p>Factor 3-Promotion of intercommunity trust and ties [3 items; MEAN(Item10,Item11,Item12)]. </p> <p>Higher scores indicate a greater perception of the resilience of regional communities in terms of positive development and purposeful experiences for young people.</p>

Data from: New remains of the aquatic turtle Hydromedusa casamayorensis (Pleurodira, Chelidae) from the middle Eocene of Patagonia: taxonomic validation and phylogenetic relationships
Twenty- seven new specimens recovered from lower levels of the Sarmiento Formation (Casamayoran SALMA, middle Eocene) in the ¨Cañadón Hondo¨ area, Chubut (Argentina), bring new information on the Palaeogene long-necked chelid Hydromedusa casamayorensis.The discovery of cranial and postcranial remains allows a complete description of the only known extinct species of the genus Hydromedusa recognizing diagnostic characters that revalidate the taxonomic status of this species. Hydromedusa casamayorensis is incorporated into a cladistic framework of chelid turtles. The unconstrained and constrained phylogenetic analyses recovered H. casamayorensis as a sister taxon of Hydromedusa maximiliani plus H. tectifera. A Danian age is proposed at least for the origin of the Hydromedusa clade, while a Late Cretaceous is suggested for the age of the split from the Yaminuechelys clade. Great differences in size are documented for H. casamayorensis based on the various specimens recovered from this study. The osteohistological study in H. casamayorensis and H. tectifera shows similarities in the internal cortex and cancellous bone of both taxa, but some differences are observed in the external cortex of H. casamayorensis (e.g. a parallel fibered bone on the more external surface of this cortex).
