2018 Aging and Disease  
Intravenous thrombolysis (IVT) with recombinant tissue plasminogen activator (rt-PA) can improve clinical outcome in eligible patients with acute ischemic stroke (AIS). However, its efficacy is strongly time-dependent. This study was aimed to examine whether prehospital notification by emergency medical service (EMS) providers could reduce onset to needle time (ONT) and improve neurological outcome in AIS patients who received IVT. We prospectively collected the consecutive clinical and time

Patients were divided into three groups, including patients that transferred by EMS with and without PNP and other means of transportation (non-EMS). We then compared the effect of EMS with PNP and EMS use only on ONT, and the subsequent neurological outcome. Good outcome was defined as modified Rankin Scale score of 0-2 at 3-months. In 182 patients included in this study, 77 (42.3%) patients were transferred by EMS, of whom 41 (53.2%) patients entered PNP. Compared with non-EMS group, EMS without PNP group greatly shortened the onset to door time (ODT), but EMS with PNP group showed both a significantly shorter DNT (41.3 ± 10.7 min vs 51.9±23.8 min, t=2.583, p=0.012) and ODT (133.2 ± 90.2 min vs 174.8 ± 105.1 min, t=2.228, p=0.027) than non-EMS group. Multivariate analysis showed that the use of EMS with PNP (OR=2.613, p=0.036), but not EMS (OR=1.865, p=0.103), was independently associated with good outcome after adjusting for age and baseline NIHSS score. When adding ONT into the regression model, ONT (OR=0.994, p=0.001), but not EMS with PNP (OR=1.785, p=0.236), was independently associated with good outcome. EMS with PNP, rather than EMS only, improved stroke outcome by shortening ONT. PNP could be a feasible strategy for better stroke care in Chinese urban area.

2021 Stroke and Vascular Neurology  
BackgroundsThe timely identification of large vessel occlusion (LVO) in the prehospital stage is extremely important given the disease morbidity and narrow time window for intervention. The current evaluation strategies still remain challenging. The goal of this study was to develop a machine learning (ML) model to predict LVO using prehospital accessible data.MethodsConsecutive acute ischaemic stroke patients who underwent CT or MR angiography and received reperfusion therapy within 8 hours

We developed eight ML models to integrate National Institutes of Health Stroke Scale (NIHSS) items with demographics, medical history and vascular risk factors to identify LVO and validate its efficiency.ResultsFinally, 15 365 patients were included in the training set and 4215 patients were included in the test set. On the test set, random forests (RF), gradient boosting machine and extreme gradient boosting presented area under the curve (AUC) of 0.831 (95% CI 0.819 to 0.843), which were higher than other models, and RF presented the highest specificity (0.827). In addition, the AUC of RF was higher than other scales, and the accuracy of the model was improved by 6.4% compared with NIHSS. We also found the top five items of identifying LVO were total NIHSS score, gaze deviation, level of consciousness (LOC), LOC commands and motor left leg.ConclusionsOur proposed model could be a useful screening tool to predict LVO based on the prehospital accessible medical data.Trial registration numberNCT04487340.

A new approach based on particle filter for target tracking with glint noise

Jungen Zhang, Hongbing Ji, Qikun Xue
2009 2009 IEEE International Conference on Systems, Man and Cybernetics  
In radar target tracking application, the observation noise is usually non-Gaussian, which is also referred to as glint noise. The performances of conventional trackers degrade severely in the presence of glint noise. An improved particle filter, Markov chain Monte Carlo iterated extended Kalman particle filter (MCMC-IEKPF), is applied to this problem. The tracking performance of the filter is evaluated and compared to the particle filter (PF) and the Markov chain Monte Carlo particle filter

2013 Food Science and Human Wellness  
Furan (C 4 H 4 O) has been classified as a possible animal and human carcinogen by many international agencies. The formation of furan in three sugar-glycine models using glucose, fructose, and sucrose was investigated using headspace gas chromatography mass spectrometry method (HS-GC-MS) with various dual combinations of three important heat processing conditions, i.e. pH, temperature, and heating time. Results indicated that furan levels from sugar-glycine model systems during the thermal

In glucose-glycine and fructose-glycine system, the lowest furan level was detected in acid condition but in sucrose-glycine system furan formed significantly lower (P < 0.05) in acidic conditions the lowest furan level was found in alkaline conditions. The furan levels were observed to increase with heating time in all three model systems. Furthermore, less furan was generated in non-reducing sugar system (sucrose) than in reducing sugar system (glucose and fructose). Therefore, they demonstrate the possibility of limiting the formation of furan in heat processed foods by both the careful selection of carbohydrates (i.e. non-reducing sugars and reducing sugars) ingredients and appropriate processing conditions.

Global analysis of gene expression in flower buds of Ms-cd1 Brassica oleracea conferring male sterility by using an Arabidopsis microarray

Jungen Kang, Guoyu Zhang, Guusje Bonnema, Zhiyuan Fang, Xiaowu Wang
2007 Plant Molecular Biology  
The dominant male sterility gene Ms-cd1 is identified in Brassica oleracea. Electron microscopical observations revealed that abortion of pollen development starts after tetrad formation. This important male sterility phenotype is characterized by lack of degradation of the primary pollen mother cell (PMC) wall and delayed degradation of callose surrounding the tetrads and thus arrest of microspore release. Gene expression of the male sterile and fertile buds was analyzed by heterologous

A total of 277 suppressed genes including 40 kinase-, 32 cell wall modification and 29 transport related genes were found to be significantly down regulated [3-fold in the male sterile mutant. The vast majority of the differentially expressed transcripts are found to present late pollen stage specific genes. Kinase genes, cell wall modification genes and ion transport genes were greatly over-represented when compared to their percentage of all flower bud expressed genes and represent 36.5% of the genes suppressed by Ms-cd1. Our results also suggest that Ms-cd1 may blocks an anther developmental pathway with a small number of genes suppressed in tapetum cells which prevent the degradation of callose and PMC wall, which further leads to the suppression of a large number of genes involved in signaling pathways, cell wall modification and ion transport in pollen grains.

Cabbage Fusarium wilt is a major disease worldwide that can cause severe yield loss in cabbage (Brassica olerecea). Although markers linked to the resistance gene FOC1 have been identified, no candidate gene for it has been determined so far. In this study, we report the fine mapping and analysis of a candidate gene for FOC1 using a double haploid (DH) population with 160 lines and a F 2 population of 4000 individuals derived from the same parental lines. Results: We confirmed that the

Using InDel primers designed from whole-genome re-sequencing data for the two parental lines (the resistant inbred-line 99-77 and the highly susceptible line 99-91) and the DH population, we mapped the resistance gene to a 382-kb genomic region on chromosome C06. Using the F 2 population, we narrowed the region to an 84-kb interval that harbored ten genes, including four probable resistance genes (R genes): Bol037156, Bol037157, Bol037158 and Bol037161 according to the gene annotations from BRAD, the genomic database for B. oleracea. After correcting the model of the these genes, we re-predicted two R genes in the target region: re-Bol037156 and re-Bol0371578. The latter was excluded after we compared the two genes' sequences between ten resistant materials and ten susceptible materials. For re-Bol037156, we found high identity among the sequences of the resistant lines, while among the susceptible lines, there were two types of InDels (a 1-bp insertion and a 10-bp deletion), each of which caused a frameshift and terminating mutation in the cDNA sequences. Further sequence analysis of the two InDel loci from 80 lines (40 resistant and 40 susceptible) also showed that all 40 R lines had no InDel mutation while 39 out of 40 S lines matched the two types of loci. Thus re-Bol037156 was identified as a likely candidate gene for FOC1 in cabbage. Conclusions: This work may lay the foundation for marker-assisted selection as well as for further function analysis of the FOC1 gene.
