Authors: Li Meng , Meng Yingying , Zheng Yongjun 
Published: October 2019

Abstract
In this paper, we use chitosan as template molecule and N-[2-(dimethylamino) ethyl]-N’-[(2-hydroxy-4-vinylphenyl)] oxamide (H3eoxdmpe) as bridge ligand and directionally synthesize N-[2-(dimethylamino) ethyl]-N’-[(2-hydroxy-4-vinylphenyl)] oxamide dinuclear zinc-chitosan [Zn2 (eoxdmpe) (tetrachit)] (ClO4) coordination monomer. We study the interaction between complex and template molecules by ultraviolet spectrophotometry and the recognition ability of complex to monosaccharide molecule quantitatively by formula. The crystal structures of N-[2-(dimethylamino) ethyl]-N’-(2-hydroxy-4-vinylphenyl)] oxamide binuclear zinc-chitosan complex are determined and analyzed by X-ray single crystal diffractive technique and the results show that the metal coordination bond is a favorable binding activity for chitosan. This study provides an ideal model for the construction of metal coordination molecularly imprinted polymers which are selectively recognized by chitosan.

Published: October 2019

Abstract
With the vigorous development of technologies such as the Internet, Internet of Things, and cloud computing, terms such as “car networking” and “intelligent transport” have gradually appeared in people’s field of vision. Traffic information has become more and more timely and comprehensive, which has gradually improved the transportation system. From the perspective of traffic participants’ knowledge of information, this paper studies the impact of traffic information coverage on traffic congestion. First, the author established a mathematical model based on optimization theory. Then through simulation, the author simulates the traffic congestion situation in different scenarios (traffic participants have different information), and then obtains the following conclusions: Traffic participants who are completely random or choose their path according to their own preferences will affect road traffic efficiency and cause traffic congestion. In addition, the traffic information coverage rate is not as high as possible, but there is an optimal coverage rate. Finally, through the analysis of the Sancha Road network system, the author has obtained the following conclusion: It is a reasonable situation to set 73% of traffic participants’ information transparency, that is, the information coverage rate is 73%.

Node Reputation-Based Replica Replication Strategy in P2P Networks
Authors: Zhu Yongqiong 
Published: October 2019

Abstract
Replica technology increases the reliability and availability of data by increasing the redundancy of data in the system. The existing replica replication algorithm only depends on the access traffic of the node when selecting the replication node, ignoring the non-cooperation of the node, resulting in a decrease in the utilization of the replica. This paper proposes an adaptive replica management policy PCA based on node reputation. PCA selects nodes with large query traffic and high reputation as replication nodes to ensure high query hit rate. Because PCA sets the copy according to the cooperation of the node, it avoids the waste of copy caused by setting the copy on the non-cooperative node, and guarantees high copy utilization.

Authors: Zheng Lei , Huang Shenghui , Mu Nengjiang , Zhang Haoyue , Zhang Jiayu , Chang Yu , Yang Lei , Zuo Yongchun 
Published: October 2019

AbstractBy reducing amino acid alphabet, the protein complexity can be significantly simplified, which could improve computational efficiency, decrease information redundancy and reduce chance of overfitting. Although some reduced alphabets have been proposed, different classification rules could produce distinctive results for protein sequence analysis. Thus, it is urgent to construct a systematical frame for reduced alphabets. In this work, we constructed a comprehensive web server called RAACBook for protein sequence analysis and machine learning application by integrating reduction alphabets. The web server contains three parts: (i) 74 types of reduced amino acid alphabet were manually extracted to generate 673 reduced amino acid clusters (RAACs) for dealing with unique protein problems. It is easy for users to select desired RAACs from a multilayer browser tool. (ii) An online tool was developed to analyze primary sequence of protein. The tool could produce K-tuple reduced amino acid composition by defining three correlation parameters (K-tuple, g-gap, λ-correlation). The results are visualized as sequence alignment, mergence of RAA composition, feature distribution and logo of reduced sequence. (iii) The machine learning server is provided to train the model of protein classification based on K-tuple RAAC. The optimal model could be selected according to the evaluation indexes (ROC, AUC, MCC, etc.). In conclusion, RAACBook presents a powerful and user-friendly service in protein sequence analysis and computational proteomics.

3044Exploration of biomarkers for subclinical atherosclerosis in an African population using a proteomics chip targeted at inflammation and cardiovascular disease
Authors: Jujic A , Malan L , Mels C , Nilsson P M , Magnusson M 
Published: October 2019

Abstract

Introduction
The evolving use of multiplex proteomic platforms provides an excellent tool for investigating associations between multiple proteins and subclinical atherosclerotic disease. In this study, we evaluated the impact of a multiplex protein panel, on carotid intima-media thickness (cIMT) as a marker of subclinical atherosclerosis.

Purpose
We used a multiplex proteomic platform to identify possible associations between proteins and subclinical carotid atherosclerosis as measured by carotid ultrasound in an African population.

Methods
In the Sympathetic Activity and Ambulatory Blood Pressure in Africans (SABPA) study, 92 proteins from the Proseek Multiplex CVD III 96×96 (Olink Bioscience, Sweden) were analyzed in 378 participants (mean age 44.7±9.6 years, 50.6% women, 10.8% with known cardiovascular disease). Carotid ultrasound was performed for measurements of the carotid intima-media thickness (cIMT, mean 0.663±0.127 mm) and calculation of cross-sectional wall area (CSWA, mean 13.5±4.4mm2), a measure of target organ damage. Possible associations between the proteins, and cIMT and CSWA, respectively, were explored using linear regression models. A two-sided Bonferroni corrected P-value of 0.05/92=5.4x10–4 was considered statistically significant in the crude analysis.

Results
Of 18 proteins (1 standard deviation of change of ln-transformed values) that were Bonferroni-corrected (p≤5.4x10–4) significantly associated with cIMT and/or CWAS in crude analyses, the following remained significant after further adjustment for age, sex, waist circumference, systolic blood pressure, smoking and total cholesterol: growth-differentiation factor-15 (GDF15; β 0.017, p=0.050), E-selectin (SELE; β 0.019, p=0.017), carboxypeptidase A1 (CPA1; β 0.019, p=0.019), C-C motif chemokine 15 (CCL15; β 0.031, p<0.001), chitinase-3-like protein 1 (CHI3L1; β 0.021, p=0.007), the hemoglobin scavenger receptor (CD163; β 0.021, p=0.008) and osteoprotegerin (OPG; β 0.022, p=0.004). As for target-organ damage defined by CSWA, SELE (β 0.459, p=0.018), CCL15 (β 0.398; p=0.032) and CD163 (β 0.541, p=0.005) showed multivariate adjusted significant associations.

Conclusion
In an African population, we could confirm five proteins (GDF15, SELE, CHI3L1, CD163 and OPG) associated with cIMT, but in addition identified two proteins (CPA1 and CCL15) with novel associations with cIMT and/or CSWA.

Abstract

Aims
To provide long-term clinical (incl neurologic) and duplex ultrasound (DUS) evaluation of the CGuard MicroNet-covered embolic prevention stent system (EPS) routine use to perform CAS in all-comer (no exclusion criteria) patients with symptomatic or increased-stroke-risk asymptomatic carotid stenosis recommended for revascularization by the NeuroVascular Team.

Methods and results
PARADIGM-Extend is a non-industry-funded, prospective academic study in all-referrals-tracked symptomatic and asymptomatic carotid stenosis. In asymptomatic lesions, intervention is mandated only in case of increased-stroke-risk features. There is first-line consideration to use the study device, with EPD choice according to tailored-CAS algorithm. Independent neurologist evaluation and DUS are performed before CAS, at 48h, 30 days, and then every 12 months. There is external source data verification, external angiographic corelab, and external statistical analysis. Currently 325 patients (48–87 years, 54.2% symptomatic) crossed the 1st follow-up window. There has been 100% CGuardEPS use. Angiographic DS was reduced from 84±8% to only 6.9±5% (p<0.001, “CEA-like” effect of CAS).
Peri-procedural death or major stroke rate was 0%. One event was CEC-adjudicated as minor stroke (0.3%), and there was one (type2) MI (0.3%). By 30 days there was one haemorrhagic transformation leading to death (0.3%) and one bleeding-related death (0.3%). Thus total death/major stroke/minor stroke rate at 30 days was 0.9%, and total death/major stroke/minor stroke/MI rate at 30 days was 1.2%. At 1- 12 months were no strokes or stroke-related deaths (0%). At 12–24 months there was one cerebellar stroke in an AFib patient that was confirmed on MRI imaging but no carotid-territory stroke or stroke deaths (0%). By 24 and 36 months there was one posterior circulation (cerebellal) infarct but no cerebral infarctions. Post-procedural in-stent velocities were normal and remained normal throughout the 36-month follow-up period (peak-systolic/end-diastolic velocity 0.69±0.29/0.18±0.09 m/s at 30 days, 0.82±0.47/0.22±0.13m/s at 12 months, 0.73±0.31/0.19±0.09m/s at 24months and 0.80±0.31/0.21±0.11 at 24months), indicating normal device healing.

Conclusions
PARADIGM-Extend accumulating 36-month clinical and DUS evidence is consistent with unprecedented, sustained safety and cerebral embolism prevention efficacy of the CGuard™ MicroNET-covered embolic prevention stent system used routinely for stroke prevention in symptomatic and increased-stroke-risk asymptomatic subjects with carotid stenosis.
