2POST-STROKE ANTIHYPERTENSIVE TREATMENT STUDY A PRELIMINARY RESULT显示文摘Post-stroke Antihypertensive Treatment Study (PATS) was a randomized, double-blind and placebo-controlled trial, which aimed at determining whether antihypertensive treatment could reduce the risk of fatal and nonfatal stroke incidence in patients with a history of stroke or transient ischemic attack (TLA). 5 665 patients were randomized by a sealed envelope system. Systolic blood pressure (SBP) ranged from 80 to 280 mm Hg and diastolic (DBP) from 50 to 150 mmHg. The average SBP was 154 mmHg and average DBP 93 mmHg. The mean age was 60 years. Among the patients, women accounted for 28%. In 71% the latest stroke was ischemic. Average follow-up approximated to 2 years. The three-year average SBP was 149 mmHg for the placebo group and 144 mmHg for the indapamide treatment group, and the three-year DBP was 89 mmHg and 87 mmHg respectively. The three-year first incidence of fatal and nonfatal stroke was 12.3 per 100 patients placebo treatment and 9.4 per 100 with indapamide.

8Protective effects ofLactobacillus plantarum against epithelial barrier dysfunction of human colon cell line NCM460显示文摘AIM: To investigate the effects of Lactobacillus plantarum (L. plantarum ) in the intestinal permeability and expression of tight junction (TJ) using the normal human colon cell line NCM460. METHODS: Paracellular permeability of NCM460 monolayers was determined by transepithelial electrical resistance and dextran permeability. Expression of TJ proteins in NCM460 cell monolayers was detected by Western blotting and quantitative real-time polymerase chain reaction.RESULTS: L. plantarum played an important role in increasing transepithelial electrical resistance and decreasing the permeability to macromolecules of NCM460 monolayers against the disruption caused by enteropathogenic Escherichia coli (E. coli ) or enteroinvasive E. coli . L. plantarum also prevented the decrease in the expression of TJ proteins and F-actin in NCM460 cells.CONCLUSION: L. plantarum can protect against dysfunction of NCM460 intestinal epithelial barrier caused by enteropathogenic E. coli or enteroinvasive E. coli , and thus can be a potential candidate of therapeutic agents for the treatment of intestinal diseases.Mary Pat Moyer 2010World Journal of Gastroenterology2010,16,45:6
9Epithelial-mesenchymal transition as a therapeutic target for overcoming chemoresistance in pancreatic cancer显示文摘Pancreatic cancer has one of the worst prognoses among all cancers due to the late manifestation of identifiable symptoms and high resistance to chemo- and radiation therapies. In recent years, a cancer development phase termed epithelial-mesenchymal transition(EMT) has gained increasing research focus. The process is implicated in tumour metastasis, and emerging evidence suggests EMT also contributes or induces chemoresistance in several cancers. Nevertheless, the applicability of therapeutic targeting of EMT faces many challenges. In this mini-review, we summarise the evidence supporting the role of EMT in pancreatic cancer progression, focusing particularly on its association with chemoresistance.Omar Elaskalani Norbaini Binti Abdol Razak Marco Falasca Pat Metharom 2017World Journal of Gastrointestinal Oncology2017,9,1:6

11植物基因组重复序列研究进展显示文摘重复序列是指基因组中频繁出现的相同或对称的DNA片段,在植物基因组中占有很大比重。重复序列分为2种类型:一种是串联重复序列,主要分布在染色体着丝粒周缘区域、臂间区域和近端粒区域,某些短的串联重复序列均匀分布在基因组中;另一种是散在重复序列,主要是反转录转座子和DNA转座子,通常散布在染色体或多倍体物种某些(个)亚基因组染色体上。目前重复序列的发现和识别技术已成为基因组学的研究热点,归纳这方面的研究进展,概括相关工具的分析特点,总结重复序列功能研究及其在遗传分析中的应用案例,可为发掘重复序列存在的生物学意义及其在物种亲缘关系分析和种质资源鉴定中的应用奠定基础。李晓宇 徐文魁 Pat Heslop HARRISON 刘青 2019扬州大学学报(农业与生命科学版)2019,40,5:5

15PI controller relay auto-tuning using delay and phase margin in PMSM drives显示文摘This paper presents an auto-tuning method for a proportion plus integral(PI) controller for permanent magnet synchronous motor(PMSM) drives, which is supposed to be embedded in electro-mechanical actuator(EMA) control module in aircraft. The method, based on a relay feedback with variable delay time, explores different critical points of the system frequency response.The Nyquist points of the plant can then be derived from the delay time and filter time constant.The coefficients of the PI controller can then be obtained by calculation while shifting the Nyquist point to a specific position to obtain the required phase margin. The major advantage of the autotuning method is that it can provide a series of tuning results for different system bandwidths and damping ratios, corresponding to the specification for delay time and phase margin. Simulation and experimental results for the PMSM controller verify the performance of both the current loop and the speed loop auto-tuning.Wang Lina Xiao Kun Liliana de Lillo Lee Empringham Pat Wheeler 2014Chinese Journal of Aeronautics2014,27,6:4

17Involvement and therapeutic implications of airway epithelial barrier dysfunction in type 2 inflammation of asthma显示文摘Type 2 inflammation is a complex immune response and primary mechanism for several common allergic diseases including allergic rhinitis,allergic asthma,atopic dermatitis,and chronic rhinosinusitis with nasal polyps.It is the predominant type of immune response against helminths to prevent their tissue infiltration and induce their expulsion.Recent studies suggest that epithelial barrier dysfunction contributes to the development of type 2 inflammation in asthma,which may partly explain the increasing prevalence of asthma in China and around the globe.The epithelial barrier hypothesis has recently been proposed and has received great interest from the scientific community.The development of leaky epithelial barriers leads to microbial dysbiosis and the translocation of bacteria to inter-and sub-epithelial areas and the development of epithelial tissue inflammation.Accordingly,preventing the impairment and promoting the restoration of a deteriorated airway epithelial barrier represents a promising strategy for the treatment of asthma.This review introduces the interaction between type 2 inflammation and the airway epithelial barrier in asthma,the structure and molecular composition of the airway epithelial barrier,and the assessment of epithelial barrier integrity.The role of airway epithelial barrier disruption in the pathogenesis of asthma will be discussed.In addition,the possible mechanisms underlying the airway epithelial barrier dysfunction induced by allergens and environmental pollutants,and current treatments to restore the airway epithelial barrier are reviewed.Xiang Dong Mei Ding Jinjin Zhang Ismail Ogülür Yagiz Pat Mübeccel Akdis Yadong Gao Cezmi A.Akdis 2022Chinese Medical Journal2022,,5:4
18A simulation study of using active traffic management strategies on congested freeways显示文摘The main objective of this study is to evaluate the effectiveness of using active traffic management (ATM) strategies on freeways in terms of the driver's behavior and operational impacts. A few test beds were selected to evaluate the impacts of ATM such as speed harmonization, shoulder utilization, and ramp metering. Test beds used in this study were at places where an ATM is either proposed or previously implemented, i.e., where data exists for conditions prior to and after the implementation of ATM. Data collected from the test beds were used in a simulation model to evaluate the impacts of each ATM strategy on speed, travel time, and crash rates. Simulation results indicated that the implementation of speed harmonization on US 90 showed a 14% reduction in crashes and a 2%-3% increase in freeway speed; the implementation of hard shoulders on US 90 showed a 39% increase in travel time, 22% increase in freeway capacity and 60% decrease in delays; and the implementation of ramp metering on US 59 between Bissonnet St. and Fondern road showed a decrease of 23 % in freeway travel time, a 14% increase in freeway speed and 11% decrease in accident rates.Ramakrishna VADDE Joseph O.
