Supporting Data:A pleiotropic 'stretch' phenotype is associated with metaxylem vessel element length, axial hydraulic conductance, root elongation, water utilization, and drought adaptation in maize.
<p>These data were collected to assess how xylem perforation plates affect water use strategies in maize (<em>Zea mays </em>L.) under water deficit through empirical studies in controlled environments and in the field. In this work, our goals were to explore the extent of intraspecific variation for the structure of perforation plates within an annual monocot and assess how this variation affects transport and use of water under drought stress. Specifically, we test the hypotheses that (1) simple perforation plates have a significant effect on water transport, (2) intraspecific variation exists for these features in maize, and (3) this variation affects water use strategies under drought stress. </p>

Cerebral small vessel disease MRI features do not improve the prediction of stroke outcome
<p class="Pardfaut"><span>Objective: To determine whether the total small vessel disease (SVD) score adds information to the prediction of stroke outcome compared to validated predictors, we tested different predictive models of outcome in stroke patients.</span></p> <p class="Pardfaut"><span>Methods: White matter hyperintensity, lacunes, perivascular spaces, microbleeds, and atrophy were quantified in two prospective datasets of 428 and 197 first-ever stroke patients, using MRI collected 24-to-72 hours after stroke onset. Functional, cognitive, and psychological status were assessed at the 3–6 month follow-up. The predictive accuracy (in terms of calibration and discrimination) of age, baseline NIHSS, and infarct volume was quantified (model-1) on dataset-1, the total SVD score was added (model-2), and the improvement in predictive accuracy was evaluated. These two models were also developed in dataset-2 for replication. Finally, in model-3, the MRI features of cerebral SVD were included rather than the total SVD score. </span></p> <p class="Pardfaut"><span>Results: Model-1 showed excellent performance for discriminating poor vs. good functional outcomes (AUC=0.915), and fair performance for identifying cognitively impaired and depressed patients (AUCs, 0.750 and 0.688 respectively). A higher SVD score was associated with a poorer outcome (odds ratio=1.30 [1.07, 1.58], p=0.0090 at best for functional outcome). However, adding the total SVD score (model-2) or individual MRI features (model-3) did not improve the prediction over model-1. Results for dataset-2 were similar. </span></p> <p class="Pardfaut"><span>Conclusions: Cerebral SVD was independently associated with functional, cognitive, and psychological outcomes, but had no clinically relevant added value to predict the individual outcomes of patients when compared to the usual predictors, such as age and baseline NIHSS.</span></p>
Intracranial aneurysm risk scores, hemodynamics and vessel wall enhancement values
<p>Vessel wall enhancement (VWE) in contrast-enhanced magnetic resonance imaging (MRI) is a potential biomarker for intracranial aneurysm (IA) risk stratification. In this study, we investigated the relationship between VWE features, risk metrics, morphology, and hemodynamics in 41 unruptured aneurysms. We reconstructed the IA geometries from MR angiography and mapped pituitary stalk-normalized MRI intensity on the aneurysm surface using an in-house tool. For each case, we calculated the maximum intensity (CRstalk) and IA risk (via size and the rupture resemblance score-RRS). We performed correlation analysis to assess relationships between CRstalk and IA risk metrics (size and RRS), as well as each parameter encompassed in RRS, i.e. aneurysmal Size Ratio (SR), normalized wall shear stress (WSS), and oscillatory shear index (OSI). We found that CRstalk had a strong correlation (Pearson correlation coefficient, PCC=0.630) with size and a moderate correlation (PCC=0.472) with RRS, indicating an association between VWE and IA risk. Furthermore, CRstalk had a weak negative correlation with normalized WSS (PCC=-0.320) and a weak positive correlation with SR (PCC= 0.390). Local voxel-based analysis showed only a weak negative correlation between normalized WSS and contrast-enhanced MRI signal intensity (PCC=-0.240), suggesting that if low normalized WSS induces enhancement-associated pathobiology, the effect is not localized.</p>
