SMCV– had supplementary value to baseline ischemic core volume in predicting midline shift.]]> Wed 05 Oct 2022 15:04:56 AEDT ]]> Numerical modelling of vapour-ice desublimation process in unsaturated freezing soils https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:43812 Tue 04 Oct 2022 09:40:36 AEDT ]]> Absent filling of ipsilateral superficial middle cerebral vein is associated with poor outcome after reperfusion therapy https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:30493 2; odds ratio, 2.710; P=0.040). No difference was found in reperfusion rate after treatment between patients with and without SMCV-(P > 0.05). In patients achieving major reperfusion (=80%), there was no difference in 24-hour infarct volume, or rate of poor outcome between patients with and without SMCV-(P > 0.05). However, in those without major reperfusion, patients with SMCV-had larger 24-hour infarct volume (P=0.011), higher rate of poor outcome (P=0.012), and death (P=0.032) compared with those with SMCV filling. SMCV-was significantly associated with brain edema at 24 hours (P=0.037), which, in turn, was associated with poor 3-month outcome (P=0.002). Conclusions: Lack of SMCV filling contributed to poor outcome after thrombolysis, especially when reperfusion was not achieved. The main deleterious effect of poor venous filling appears related to the development of brain edema.]]> Thu 28 Oct 2021 13:03:14 AEDT ]]> A semi-analytical model for a compaction-grouted soil nail with double grout bulbs considering compaction effect in sand https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:40108 Thu 28 Jul 2022 15:29:21 AEST ]]> Negative Effect of Installation on Performance of a Compaction-Grouted Soil Nail in Poorly Graded Stockton Beach Sand https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:41002 Thu 21 Jul 2022 10:44:18 AEST ]]> A cavity expansion theory-based hyperbolic model for the pull-out force of a compaction-grouted soil nail https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:54286 Thu 15 Feb 2024 14:44:55 AEDT ]]> Analytical Study on the Pullout Distribution of an Anchor with Multiple Grout Bulbs https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:54814 Thu 14 Mar 2024 14:31:47 AEDT ]]> Reperfusion facilitates reversible disruption of the human blood-brain barrier following acute ischaemic stroke https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:36740 hypo-i), non-hypoperfused region of ischaemic hemisphere (rPSnonhypo-i) and their contralateral mirror regions (rPShypo-c and rPSnonhypo-c). The changes of rPS were analysed using analysis of variance (ANOVA) with repeated measures. Logistic regression was used to identify independent predictors of unfavourable outcome. Results: Fifty-six patients were included in the analysis, median age was 76 (IQR 62-81) years and 28 (50%) were female. From baseline to 24 h after treatment, rPShypo-i, rPSnonhypo-i and rPShypo-c all decreased significantly. The decreases in rPShypo-i and rPShypo-c were larger in the reperfusion group than non-reperfusion group. The rPShypo-i at follow-up was a predictor for unfavourable outcome (OR 1.131; 95% CI 1.018-1.256; P = 0.022). Conclusion: Early disruption of BBB in AIS is reversible, particularly when greater reperfusion is achieved. Elevated BBBP at 24 h after treatment, not the pretreatment BBBP, predicts unfavourable outcome. Key points: Early disruption of blood-brain barrier (BBB) in stroke is reversible after treatment; The reversibility of BBB permeability is associated with reperfusion; Unfavourable outcome is associated with BBB permeability at 24 h after treatment; Contralateral non-ischaemic hemisphere is not 'normal' during an acute stroke.]]> Thu 02 Jul 2020 16:31:45 AEST ]]> Prehospital notification procedure improves stroke outcome by shortening onset to needle time in Chinese urban area https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:41242 Sat 30 Jul 2022 12:26:18 AEST ]]> A theoretical method for determining sample mass in a sieving test https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:31276 Sat 24 Mar 2018 08:44:32 AEDT ]]> Possible frost heave mechanisms in an unsaturated high-speed railway formation https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:20746 Sat 24 Mar 2018 08:00:22 AEDT ]]> Unanswered questions in unsaturated soil mechanics https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:19696 Sat 24 Mar 2018 07:53:49 AEDT ]]> Assessing frost susceptibility of soils using PCHeave https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:19697 Sat 24 Mar 2018 07:53:48 AEDT ]]> Optimal magnetic resonance perfusion thresholds identifying ischemic penumbra and infarct core: a Chinese population-based study https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:26920 70% reperfusion at 24 h) were enrolled to investigate the ischemic penumbra and infarct core, respectively. The final infarct was assessed on 24-h diffusion-weighted imaging (DWI), which was retrospectively matched to the baseline perfusion-weighted imaging (PWI) images by volume or voxel-based analysis. The optimal thresholds that determined by each approach were compared. Results: From June 2009 to Jan 2014, of 50 patients enrolled, 19 patients achieved no reperfusion, and 20 patients reperfused at 24 h. In patients with no reperfusion, Tmax > 6 seconds was proved of the best agreement with the final infarct in both volumetric analysis (ratio: 1.05, 95% limits of agreement:-0.23 to 2.33, P < 0.001) and voxel-by-voxel analysis (sensitivity: 72.3%, specificity: 74.3%). In patients with reperfusion, rMTT>225% (ratio:2.4, 95% limits of agreement: -6.5 to 11.4, P < 0.001) was found of the best volumetric agreement with the final infarct, while Tmax > 5.6 seconds (sensitivity: 76.8%, specificity: 70.3%) performed most accurately in voxel-based analysis. Conclusion: Among Chinese acute stroke patients, volume of Tmax >6 seconds may precisely target ischemic penumbra tissue as good as voxel-based analysis performed, albeit no concordant MRP parameter is found to accurately predict infarct core because reperfusion occurred within 24 h after thrombolysis fails to restrain the infarct growth.]]> Sat 24 Mar 2018 07:23:34 AEDT ]]> Analysis of frost heave mechanisms in a high-speed railway embankment https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:24960 Sat 24 Mar 2018 07:14:16 AEDT ]]> Influences of self-organization of granular materials on particle crushing based on discrete element method https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:45509 Mon 31 Oct 2022 08:40:57 AEDT ]]> Delayed filling of the superficial middle cerebral vein in acute large artery occlusion https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:52319 Mon 22 Apr 2024 14:04:17 AEST ]]> Filling Defect of Ipsilateral Transverse Sinus in Acute Large Artery Occlusion https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:51794 0.05).

A database of 53 granular soils with 154 varying PSD curves is analyzed to evaluate the performance of the proposed PSD model, as well as that of three other PSD models in the literature. The results show that the proposed model has improved overall performance and captures the typical trends in PSD evolution during particle breakage. In addition, the proposed model is also used for assessing the internal stability of 27 widely graded soils.]]> Fri 06 Mar 2020 12:15:42 AEDT ]]> The velocity of collateral filling predicts recanalization in acute ischemic stroke after intravenous thrombolysis https://novaprd-lb.newcastle.edu.au/vital/access/ /manager/Repository/uon:29190 p = 0.020), but not tMIP-ASPECT score (OR = 1.073, 95% CI = 0.820–1.405, p = 0.607), was independently associated with recanalization (AOL score of 2 and 3) at 24 hours after IVT. When recanalization was achieved, hemorrhagic transformation (HT) occurred more frequently in patients with slow collaterals (ATD ≥ 2.3 seconds) than those with rapid collaterals (ATD < 2.3 seconds) (88.9% vs 38.1%, p = 0.011). In conclusion, the velocity of collaterals related to recanalization, which may guide the decision-making of revascularization therapy in acute ischemic stroke.]]> Fri 01 Apr 2022 09:24:17 AEDT ]]>
