| 1 | Comparative study of Mo2Ga2C with superconducting MAX phase Mo2GaC: First-principles calculations显示文摘The structural, electronic, optical and thermodynamic properties of Mo_2Ga_2C are investigated using density functional theory(DFT) within the generalized gradient approximation(GGA). The optimized crystal structure is obtained and the lattice parameters are compared with available experimental data. The electronic density of states(DOS) is calculated and analyzed. The metallic behavior for the compound is confirmed and the value of DOS at Fermi level is 4.2 states per unit cell per e V. Technologically important optical parameters(e.g., dielectric function, refractive index, absorption coefficient, photo conductivity, reflectivity, and loss function) are calculated for the first time. The study of dielectric constant(ε1) indicates the Drude-like behavior. The absorption and conductivity spectra suggest that the compound is metallic.The reflectance spectrum shows that this compound has the potential to be used as a solar reflector. The thermodynamic properties such as the temperature and pressure dependent bulk modulus, Debye temperature, specific heats, and thermal expansion coefficient of Mo_2Ga_2C MAX phase are derived from the quasi-harmonic Debye model with phononic effect also for the first time. Analysis of T c expression using available parameter values(DOS, Debye temperature, atomic mass,etc.) suggests that the compound is less likely to be superconductor. | M A Ali M R Khatun NJahan M M Hossain | 2017 | Chinese Physics B2017，26，3： | 4 |
| 2 | Development of Epstein-Barr virus-associated gastric cancer:Infection,inflammation,and oncogenesis显示文摘Epstein-Barr virus(EBV)-associated gastric cancer(EBVaGC)cells originate from a single-cell clone infected with EBV.However,more than 95%of patients with gastric cancer have a history of Helicobacter pylori(H.pylori)infection,and H.pylori is a major causative agent of gastric cancer.Therefore,it has long been argued that H.pylori infection may affect the development of EBVaGC,a subtype of gastric cancer.Atrophic gastrointestinal inflammation,a symptom of H.pylori infection,is observed in the gastric mucosa of EBVaGC.Therefore,it remains unclear whether H.pylori infection is a cofactor for gastric carcinogenesis caused by EBV infection or whether H.pylori and EBV infections act independently on gastric cancer formation.It has been reported that EBV infection assists in the oncogenesis of gastric cancer caused by H.pylori infection.In contrast,several studies have reported that H.pylori infection accelerates tumorigenesis initiated by EBV infection.By reviewing both clinical epidemiological and experimental data,we reorganized the role of H.pylori and EBV infections in gastric cancer formation. | Hisashi Iizasa Andy Visi Kartika Sintayehu Fekadu Shunpei Okada Daichi Onomura Afifah Fatimah Azzahra Ahmad Wadi Mosammat Mahmuda Khatun Thin Myat Moe Jun Nishikawa Hironori Yoshiyama | 2022 | World Journal of Gastroenterology2022，28，44： | 3 |
| 3 | n-3多不饱和脂肪酸对PM2.5暴露的2型糖尿病大鼠氧化应激和炎症的影响显示文摘目的探讨n-3多不饱和脂肪酸(polyunsaturated fatty acid,PUFA)对PM2.5暴露的2型糖尿病(type 2 diabetes,T2DM)大鼠炎症反应和氧化应激的影响。方法将70只4周龄雄性SD大鼠随机分为7组:空白对照组,T2DM模型对照组,PM2.5气管滴注组,玉米油对照组和n-3 PUFA低、中、高剂量(75、150和300 mg/kg)干预组。用高糖高脂饲料联合一次性腹腔注射STZ方法诱导大鼠2型糖尿病。造模成功后,除空白对照组和T2DM模型组外,其余5组大鼠经气管缓慢滴注PM2.5悬浮液5 mg/kg染毒,每天1次,连续1周。随后n-3 PUFA干预各组予以富含n-3 PUFA的鱼油灌胃,玉米油对照组予以等体积玉米油灌胃,每天1次,共4周。采用酶联免疫法检测大鼠血清和肝脏肿瘤坏死因子α(tumor necrosis factor-α,TNF-α)、白介素6(interleukin-6,IL-6)和白介素10(interleukin-10,IL-10)水平,免疫比浊法测定大鼠血清C反应蛋白(C-reactive protein,CRP),WST-1法检测大鼠血清和肝脏超氧化物歧化酶(superoxide dismutase,SOD)水平,硫代巴比妥酸(thiobarbituric acid,TBA)法检测丙二醛(malondialdehyde,MDA)含量,尿酸酶法测定血尿酸(serum uric acid,SUA),苏木精-伊红染色法观察肝脏石蜡切片组织病理变化。结果T2DM模型组大鼠血清IL-6和CRP水平显著高于空白对照组(P<0.05);PM2.5气管滴注组大鼠血清IL-6水平均显著高于T2DM模型组(P<0.05),n-3 PUFA各组大鼠血清IL-6水平均显著低于玉米油对照组(P<0.05)。T2DM模型组大鼠血清SOD水平显著低于空白对照组而血尿酸水平显著高于空白对照组(P<0.05);PM2.5气管滴注组大鼠肝脏MDA和血尿酸水平均显著高于T2DM模型对照组(P<0.05);各剂量n-3 PUFA干预组血尿酸水平均显著低于玉米油对照组(P<0.05)。结论PM2.5暴露增加了T2DM大鼠炎症反应和氧化应激,而n-3 PUFA干预可改善PM2.5暴露的T2DM大鼠炎症反应和氧化应激状态。 | 李向培 宋春蕾 李海霞 赵宵帝 陈淑敏 Pipasha Khatun 时宝庆 王玲 | 2020 | 卫生研究2020，49，3： | 2 |
| 4 | Analgesic,antibacterial and central nervous system depressant activities of Albizia procera leaves显示文摘Objective:To ascertain analgesic,antibacterial and central nervous system(CNS)depressant activities of ethyl acetate,dichloromethane and carbon tetrachloride fractions of methanol extract of Albizia proceru(A.procera)leaves.Methods:Leaves extracts of A.procera were tested for analgesic activity by acetic acid induced and formalin test method in mice.The in vitro antibacterial activity was performed by agar well diffusion method.CNS depressant activity was evaluated by hole cross and open field tests.Results:All the extracts at 200 mg/kg exhibited significant(P<0.01)analgesic activity in acetic acid induced and formalin tests method in mice.Analgesic activity of the ethyl acetate fraction was almost same like as standard drug indomelhacin in acetic acid induced method.The CNS depressant activity of the extracts at 500 mg/kg was comparable to the positive control diazepam as determined by hole cross and open field test method.The extracts exhibited moderate antimicrobial activity against all the tested microorganisms(Staphylococcus aureus,Bacillus cereus,Pseudomonas aeruginosa,Esherichia coli,Shigetta soneii.Shigella boydii)at concentration of 0.8 mg/disc.The measured diameter of zone of inhibition for the extracts was within the range of 7 to 12 mm which was less than the standard kanamycin(16-24 mm).Conclusions:It is concluded that all the extracts possess potential analgesic and CNS depressants activity.This study also showed that different fractions of methanol extract could be potential sources of new antimicrobial agents. | Mahfuza Khatoon Hajera Khatun Ekramul Islam Shahnaj Parvin | 2014 | Asian Pacific Journal of Tropical Biomedicine2014，4，4： | 1 |
