| 1 | Attribution of PM_(2.5) exposure in Beijing-Tianjin-Hebei region to emissions:implication to control strategies显示文摘The Beijing-Tianjin-Hebei(BTH) region is one of the most heavily polluted regions in China,with both high PM_(2.5) concentrations and a high population density.A quantitative source-receptor relationship can provide valuable insights that can inform effective emission control strategies.Both source apportionment(SA) and source sensitivity(SS) can provide such information from different perspectives.In this study,both methods are applied in northern China to identify the most significant emission categories and source regions for PM_(2.5) exposure in BTH in 2013.Despite their differences,both models show similar distribution patterns for population and simulated PM_(2.5) concentrations,resulting in overall high PM_(2.5) exposure values(approximately 110 μg/m~) and particularly high exposure values during the winter(approximately 200 μ/m~).Both methods show that local emissions play a dominant role(70%),with some contribution from surrounding provinces(e.g.,Shandong) via regional transport.The two methods also agree on the priority of local emission controls:both identify industrial,residential,and agricultural emissions as the top three categories that should be controlled locally.In addition,the effect of controlling agricultural ammonia emissions is approximately doubled when the co-benefits of reducing nitrate are considered.The synthesis of SA and SS for addressing specific categories of emissions provides a quantitative basis for the development of emission control strategies and policies for controlling PM_(2.5)in China. | Xin Li Qiang Zhang Yang Zhang Lin Zhang Yuxuan Wang Qianqian Zhang Meng Li Yixuan Zheng Guannan Geng Timothy J.Wallington Weijian Han Wei Shen Kebin He | 2017 | Science Bulletin2017,62,13: | 15 |
| 2 | Axial length development in children显示文摘AIM: To study ocular axial lengths in pediatric subjects without intraocular pathology. METHODS: An Institutional Review Board-approved consecutive retrospective chart review of axial lengths measured in pediatric subjects who underwent examination under anesthesia due to positive family history of retinoblastoma or other inherited ocular disease. Only subjects without any intraocular pathology in either eye were included. Subjects were stratified into age groups. An axial length model using a logarithmic regression algorithm was calculated.RESULTS: Data from 330 eyes of 165 subjects were included in the study. The mean age at the time of examination was 30.62(SD 18.04)mo. The steepest increase in axial length was present during the first 10 mo of life. After 36 mo, there was no statistically significant axial length growth. CONCLUSION: This study presents the biggest series of pediatric axial lengths in healthy eyes. The axial length model developed with these data may assist in the diagnosis and management of a wide variety of pediatric ophthalmic diseases. | Austin Bach Victor M.Villegas Aaron S.Gold Wei Shi Timothy G.Murray | 2019 | International Journal of Ophthalmology(English edition)2019,12,5: | 6 |
| 3 | Environmental and Psycho-social Factors Related to Prostate Cancer Risk in the Chinese Population:a Case-control Study显示文摘Objective To study the risk environmental and psycho-social factors associated to prostate cancer(PCa) in Chinese population. Methods 250 PCa patients and 500 controls were enrolled in this case-control study. Information was collected and logistic regression analysis was used to estimate the odds ratios(OR) and 95% confidence intervals(95% CI) for relationship between lifestyle, eating habits and psycho-social factors with PCa risk. Results Green vegetables and green tea were associated with a decreased risk of PCa(OR=0.39, 95% CI: 0.28-0.53; OR=0.59, 95% CI: 0.40-0.87, respectively). Family history of PCa(OR=7.16, 95% CI: 2.01-25.49), history of prostate diseases(OR=2.28, 95% CI: 1.53-3.41), alcohol consumption(OR=1.97, 95% CI: 1.33-2.90), red meat consumption(OR=1.74, 95% CI: 1.20-2.52), barbecued(OR=2.29, 95% CI: 1.11-4.73) or fried(OR=2.35, 95% CI: 1.24-4.43) foods were related with increased PCa risk. Negative psycho-social factors including occupational setbacks(OR=1.61, 95% CI: 1.00-2.59), marital separation(OR=1.94, 95% CI: 1.29-2.91), self-contained suffering(OR=2.37, 95% CI: 1.58-3.55), and high sensitivity to the personal comments(OR=1.73, 95% CI: 1.18-2.54) were related to PCa. Conclusion Regular consumption of green vegetables and green tea may suggest protective effects on PCa. Alcohol consumption, red meat consumption and barbecued or fried foods were associated with PCa. Negative psycho-social factors may also play a role in the incidence of PCa in Chinese population. | LI Mei Ling LIN Ji HOU Jian Guo XU Lei CUI Xin Gang XU Xing Xing YU Yong Wei HAN Xue WANG Guo Min GUO Jian Ming XU Dan Feng THOMPSON Timothy C CAO Guang Wen ZHANG Hong Wei | 2014 | Biomedical and Environmental Sciences2014,27,9: | 5 |
| 4 | Distribution of pericellular matrix molecules in the temporomandibular joint and their chondroprotective effects against inflammation显示文摘The objectives of this study were to(1) determine the distribution and synthesis of pericellular matrix(PCM) molecules(collagen VI, collagen IV and laminin) in rat temporomandibular joint(TMJ) and(2) investigate the effects of PCM molecules on chondrocytes against inflammation in osteoarthritis. Four zones(fibrous, proliferating, mature and hypertrophic) of condylar cartilage and three bands(anterior, intermediate and posterior) of disc were analysed by immunohistochemistry for the presence of PCM molecules in rat TMJs. Isolated chondrocytes were pre-treated with PCM molecules before being subjected to interleukin(IL)-1β treatment to stimulate inflammation. The responses of the chondrocytes were analysed using gene expression, nitric oxide release and matrix metalloproteinase(MMP)-13 production measures. Histomorphometric analyses revealed that the highest areal deposition of collagen VI(67.4%), collagen IV(45.7%) and laminin(52.4%) was in the proliferating zone of TMJ condylar cartilage. No significant difference in the distribution of PCM molecules was noted among the three bands of the TMJ disc. All three PCM molecules were expressed intracellularly by chondrocytes cultured in the monolayer. Among the PCM molecules, pre-treatment with collagen VI enhanced cellular proliferation, ameliorated IL-1β-induced MMP-3, MMP-9, MMP-13 and inducible nitric oxide synthase gene expression, and attenuated the downregulation of cartilage matrix genes, including collagen I, aggrecan and cartilage oligomeric matrix protein(COMP). Concurrently, collagen VI pretreatment inhibited nitric oxide and MMP-13 production. Our study demonstrates for the first time the distribution and role of PCM molecules, particularly collagen VI, in the protection of chondrocytes against inflammation. | Wern Cui Chu Shipin Zhang Timothy J Sng Yu Jie Ong Wen-Li Tan Vivien Y Ang Casper B Foldager Wei Seong Toh | 2017 | International Journal of Oral Science2017,9,1: | 5 |
| 5 | Particle shape characterisation and its application to discrete element modelling显示文摘Increasing importance has been placed on particle shape implementation within discrete element modelling(DEM) in order to more accurately reflect the non-spherical behaviour of the bulk material being handled. As computational resources grow, complex particle shapes are increasingly being modelled as the associated simulation times become more realistic to provide timely solutions. The objective of this research is to assess particle shape descriptors through a digital image segmentation technique, and to further implement particle shape parameters into generation of corresponding irregular shaped DEM particles. Separated and lumped particle images were analysed and reconstructed through the development of two distinct methodologies. Subsequently, various particle shape descriptors were obtained using combinations of image segmentation algorithms, including mathematical morphology processing,thresholding, edge detection, region growing, region splitting and region merging. DEM particles were subsequently created using particle shape results obtained above. Shape parameters of DEM particles were then examined and validated against the real particle shape parameters. | Kenneth C.Williams Wei Chen Sebastian Weeger Timothy J.Donohue | 2014 | Particuology2014,12,1: | 4 |
| 6 | Gastrointestinal perforation in metastatic colorectal cancer patients with peritoneal metastases receiving bevacizumab显示文摘AIM:To investigate the safety and efficacy of adding bevacizumab to first-line chemotherapy in metastatic colorectal cancer patients with peritoneal disease.METHODS:We compared rates of gastrointestinal perforation in patients with metastatic colorectal cancer and peritoneal disease receiving first-line chemotherapy with and without bevacizumab in three distinct cohorts:(1) the AGITG MAX trial(Phase Ⅲ randomised clinical trial comparing capecitabine vs capecitabine and bevacizumab vs capecitabine,bevacizumab and mitomycin C);(2) the prospective Treatment of Recurrent and Advanced Colorectal Cancer(TRACC) registry(any first-line regimen ± bevacizumab);and(3) two cancer centres in New South Wales,Australia [Macarthur Cancer Therapy Centre and Liverpool Cancer Therapy Centre(NSWCC) from January 2005 to Decenber 2012,(any first-line regimen ± bevacizumab).For the AGITG MAX trial capecitabine was compared to the other two arms(capecitabine/bevacizumab and capecitabine/bevacizumab/mitomycin C).In the AGITG MAX trial and the TRACC registry rates of gastrointestinal perforation were also collected in patients who did not have peritoneal metastases.Secondary endpoints included progression-free survival,chemotherapy duration,and overall survival.Time-toevent outcomes were estimated using the Kaplan-Meier method and compared using the log-rank test.RESULTS:Eighty-four MAX,179 TRACC and 69 NSWCC patients had peritoneal disease.There were no gastrointestinal perforations recorded in either the MAX subgroup or the NSWCC cohorts.Of the patients without peritoneal disease in the MAX trial,4/300(1.3%) in the bevacizumab arms had gastrointestinal perforations compared to 1/123(0.8%) in the capecitabine alone arm.In the TRACC registry 3/126(2.4%) patients who had received bevacizumab had a gastrointestinal perforation compared to 1/53(1.9%) in the chemotherapy alone arm.In a further analysis of patients without peritoneal metastases in the TRACC registry,the rate of gastrointestinal perforations was 9/369(2.4%) in the chemotherapy/bevacizumab group and 5/177(2.8%) in the chemotherapy alone group.The addition of bevacizumab to chemotherapy was associated with improved progression-free survival in all three cohorts:MAX 6.9 m vs 4.9 m,HR = 0.64(95%CI:0.42-1.02);P = 0.063;TRACC 9.1 m vs 5.5 m,HR = 0.61(95%CI:0.37-0.86);P = 0.009;NSWCC 8.7 m vs 6.8 m,HR = 0.75(95%CI:0.43-1.32);P = 0.32.Chemotherapy duration was similar across the groups.CONCLUSION:Patients with peritoneal disease do not appear to have an increased risk of gastrointestinal perforations when receiving first-line therapy with bevacizumab compared to systemic therapy alone. | Aflah Roohullah Hui-Li Wong Katrin M Sjoquist Peter Gibbs Kathryn Field Ben Tran Jeremy Shapiro Joe Mckendrick Desmond Yip Louise Nott Val Gebski Weng Ng Wei Chua Timothy Price Niall Tebbutt Lorraine Chantrill | 2015 | World Journal of Gastroenterology2015,21,17: | 3 |
| 7 | Development and optimization of thermal contrast amplification lateral flow immunoassays for ultrasensitive HIV p24 protein detection显示文摘Detection of human immunodeficiency virus(HIV)p24 protein at a single pg/ml concentration in point-of-care(POC)settings is important because it can facilitate acute HIV infection diagnosis with a detection sensitivity approaching that of laboratory-based assays.However,the limit of detection(LOD)of lateral flow immunoassays(LFAs),the most prominent POC diagnostic platform,falls short of that of laboratory protein detection methods such as enzyme-linked immunosorbent assay(ELISA).Here,we report the development and optimization of a thermal contrast amplification(TCA)LFA that will allow ultrasensitive detection of 8 pg/ml p24 protein spiked into human serum at POC,approaching the LOD of a laboratory test.To achieve this aim,we pursued several innovations as follows:(a)defining a new quantitative figure of merit for LFA design based on the specific to nonspecific binding ratio(BR);(b)using different sizes and shapes of gold nanoparticles(GNPs)in the systematic optimization of TCA LFA designs;and(c)exploring new laser wavelengths and power regimes for TCA LFA designs.First,we optimized the blocking buffer for the membrane and running buffer by quantitatively measuring the BR using a TCA reader.The TCA reader interprets the thermal signal(i.e.,temperature)of GNPs within the membrane when irradiated by a laser at the plasmon resonance wavelength of the particle.This process results in higher detection and quantitation of GNPs than in traditional visual detection(i.e.,color intensity).Further,we investigated the effect of laser power(30,100,200 mW),GNP size and shape(30 and 100 nm gold spheres,150 nm gold-silica shells),and laser wavelength(532,800 nm).Applying these innovations to a new TCA LFA design,we demonstrated that 100nm spheres with a 100 mW 532 nm laser provided the best performance(i.e.,LOD=8pg/ml).This LOD is significantly better than that of the current colorimetric LFA and is in the range of the laboratory-based p24 ELISA.In summary,this TCA LFA for p24 protein shows promise for detecting acute HIV infection in POC settings. | Li Zhan Timothy Granade Yilin Liu Xierong Wei Ae Youngpairoj Vickie Sullivan Jeff Johnson John Bischof | 2020 | Microsystems & Nanoengineering2020,6,1: | 3 |

| 10 | Seasonal Variations of CH_4 Emissions in the Yangtze River Delta Region of China Are Driven by Agricultural Activities显示文摘Developed regions of the world represent a major atmospheric methane(CH_4) source,but these regional emissions remain poorly constrained.The Yangtze River Delta(YRD) region of China is densely populated(about 16% of China's total population) and consists of large anthropogenic and natural CH_4 sources.Here,atmospheric CH_4 concentrations measured at a 70-m tall tower in the YRD are combined with a scale factor Bayesian inverse(SFBI) modeling approach to constrain seasonal variations in CH_4 emissions.Results indicate that in 2018 agricultural soils(AGS,rice production) were the main driver of seasonal variability in atmospheric CH_4 concentration.There was an underestimation of emissions from AGS in the a priori inventories(EDGAR—Emissions Database for Global Atmospheric Research v432 or v50),especially during the growing seasons.Posteriori CH_4 emissions from AGS accounted for 39%(4.58 Tg,EDGAR v432) to 47%(5.21 Tg,EDGAR v50) of the total CH_4 emissions.The posteriori natural emissions(including wetlands and water bodies) were1.21 Tg and 1.06 Tg,accounting for 10.1%(EDGAR v432) and 9.5%(EDGAR v50) of total emissions in the YRD in2018.Results show that the dominant factor for seasonal variations in atmospheric concentration in the YRD was AGS,followed by natural sources.In summer,AGS contributed 42%(EDGAR v432) to 64%(EDGAR v50) of the CH_4 concentration enhancement while natural sources only contributed about 10%(EDGAR v50) to 15%(EDGAR v432).In addition,the newer version of the EDGAR product(EDGAR v50) provided more reasonable seasonal distribution of CH_4 emissions from rice cultivation than the old version(EDGAR v432). | Wenjing HUANG Timothy JGRIFFIS Cheng HU Wei XIAO Xuhui LEE | 2021 | Advances in Atmospheric Sciences2021,38,9: | 2 |

| 13 | Early diagnosis and therapeutic strategies for hepatocellular carcinoma:From bench to bedside显示文摘Hepatocellular carcinoma(HCC)is the fourth leading cause of cancer-related deaths worldwide.The prognosis of patients with HCC remains poor largely due to the late diagnosis and lack of effective treatments.Despite being widely used,alpha-fetoprotein serology and ultrasonography have limited diagnostic performance for early-stage HCC.The emergence of omics strategies has contributed to significant advances in the development of non-invasive biomarkers for the early diagnosis of HCC including proteins,metabolites,circulating tumor deoxyribonucleic acid,and circulating non-coding ribonucleic acid.Early diagnosis is beneficial to patients as it increases the proportion who can be treated with curative treatment,thus prolonging survival outcomes.Currently,multiple clinical trials involving locoregional,systemic therapies,and combinations of these modalities are changing therapeutic strategies for different stage HCC.Success in several preclinical trials that involve immunotherapeutic innovations has created the potential to complement and enforce other treatment strategies in the future.This review summarizes the most recent advances in noninvasive early molecular detection,current therapy strategies,and potential immunotherapeutic innovations of HCC. | Ming-Cheng Guan Ming-Da Wang Si-Yu Liu Wei Ouyang Lei Liang Timothy M Pawlik Qiu-Ran Xu Dong-Sheng Huang Feng Shen Hong Zhu Tian Yang | 2021 | World Journal of Gastrointestinal Oncology2021,13,4: | 2 |
