| 1 | Assessment of neovascularization within carotid plaques in patients with ischemic stroke显示文摘AIM:To assess neovascularization within human ca-rotid atherosclerotic soft plaques in patients with isch-emic stroke.METHODS:Eighty-one patients with ischemic stroke and 95 patients without stroke who had soft athero-sclerotic plaques in the internal carotid artery were studied.The thickest soft plaque in each patient was examined using contrast-enhanced ultrasound.Time-intensity curves were collected from 5 s to 3 min after contrast injection.The neovascularization within the plaques in the internal carotid artery was evaluated using the ACQ software built into the scanner by 2 of the experienced investigators who were blinded to the clinical history of the patients.RESULTS:Ischemic stroke was present in 7 of 33 patients(21%) with grade Ⅰ plaque,in 14 of 51 pa-tients(28%) with grade Ⅱ plaque,in 26 of 43 patients(61%) with grade Ⅲ plaque,and in 34 of 49 patients(69%) with grade Ⅳ plaque(P < 0.001 comparing grade Ⅳ plaque with grade I plaque and with grade Ⅱ plaque and P = 0.001 comparing grade Ⅲ plaque with grade Ⅰ plaque and with grade Ⅱ plaque).Analysis of the time intensity curves revealed that patients with ischemic stroke had a significantly higher intensity of enhancement(IE) than those without ischemic stroke(P < 0.01).The wash-in time(WT) of plaque was signifi-cantly shorter in stroke patients(P < 0.05).The sensi-tivity and specificity for IE in the plaque were 82% and 80%,respectively,and for WT were 68% and 74%,respectively.There was no significant difference in the peak intensity or time to peak between the 2 groups.CONCLUSION:This study shows that the higher the grade of plaque enhancement,the higher the risk of ischemic stroke.The data suggest that the presence of neovascularization is a marker for unstable plaque. | Wilbert S Aronow Chandra K Nair David Cosgrove | 2010 | World Journal of Cardiology2010，2，4： | 29 |
| 2 | Over expression of resistin in adipose tissue of the obese induces insulin resistance显示文摘AIM: To compare resistin mRNA expression in subcutaneous adipose tissue (SAT) and its correlation with insulin resistance (IR) in postmenopausal obese women. METHODS: A total of 68 postmenopausal women (non obese = 34 and obese = 34) were enrolled for the study. The women of the two groups were age matched (49-70 years). Fasting blood samples were collected at admission and abdominal SAT was obtained during surgery for gall bladder stones or hysterectomy. Physical parameters [age, height, weight, body mass index (BMI)] were measured. Biochemical (plasma insulin and plasma glucose) parameters were estimated by enzymatic methods. RNA was isolated by the Trizol method.SAT resistin mRNA expression was done by real time- reverse transcription polymerase chain reaction (RT-PCR) by using Quanti Tect SYBR Green RT-PCR master mix. Data was analyzed using independent Student's t test, correlation and simple linear regression analysis. RESULTS: The mean weight (52.81 ± 8.04 kg vs 79.56 ± 9.91 kg; P < 0.001), BMI (20.23 ± 3.05 kg/m 2 vs 32.19 ± 4.86 kg/m 2 ; P < 0.001), insulin (8.47 ± 3.24 U/mL vs 14.67 ± 2.18 U/mL; P < 0.001), glucose (97.44 ± 11.31 mg/dL vs 109.67 ± 8.02 mg/dL; P < 0.001) and homeostasis model assessment index (2.01 ± 0.73 vs 3.96 ± 0.61; P < 0.001) were significantly higher in postmenopausal obese women compared to postmenopausal non obese women. The mean serum resistin level was also significantly higher in postmeno-pausal obese women compared to postmenopausal non obese women (9.05 ± 5.15 vs 13.92 ± 6.32, P < 0.001). Furthermore, the mean SAT resistin mRNA expression was also significantly (0.023 ± 0.008 vs 0.036 ± 0.009; P < 0.001) higher and over expressed 1.62 fold (upregulated) in postmenopausal obese women compared to postmenopausal non obese women. In postmeno-pausal obese women, the relative SAT resistin mRNA expression showed positive (direct) and significant correlation with BMI (r = 0.78, P < 0.001) and serum resistin (r = 0.76, P < 0.001). Furthermore, the SAT resistin mRNA expression in postmenopausal obese women also showed significant and direct association (r = 0.45, P < 0.01) with IR, while in postmenopausal non obese women it did not show any association (r = -0.04, P > 0.05). CONCLUSION: Increased SAT resistin mRNA expres-sion probably leads to inducing insulin resistance and thus may be associated with obesity-related disorders in postmenopausal obese women. | Sadashiv Sunita Tiwari S Dhananjai Bhola N Paul Sandeep Kumar Abhijit Chandra Mahendra PS Negi | 2012 | World Journal of Diabetes2012，3，7： | 10 |
| 3 | Cr_2O_3对高放核废料磷酸盐玻璃固化体的影响显示文摘在含高放核废料的玻璃固化体中添加了不同含量的Cr2O3,以考察其对玻璃固化体的结构和性质的影响.对添加Cr2O3的玻璃固化体进行了各种方法(溶出速率法,蒸汽水化侵蚀和试样坚固性法)的化学稳定性的测试.测试结果表明,Cr2O3的引入不会对玻璃固化体的化学稳定性产生不良的影响.与此相反,Cr2O3能抑制各种离子自玻璃固化体中沥析出来, 改善玻璃固化体的化学耐蚀性. XRD内标法测定,Cr2O3在铁磷酸盐玻璃中的溶解度可达4.1%,是其在硼硅酸盐玻璃的3倍. FTIR和DTA的结果表明,不同含量的Cr2O3的引入, 不会对玻璃固化体的网络结构造成显著的变化. Mossbauer谱表明,Fe2+/Fe3+的比值随着Cr2O3的含量的增加而增大,说明Cr离子和Fe离子在玻璃熔制过程中发生氧化还原反应, 形成的Cr+6有利于提高玻璃固化体的化学耐蚀性. | 黄文旵 周萘 Day Delbert E Ray Chandra S | 2005 | 无机材料学报2005，20，4： | 9 |
| 4 | 高放射性核废料玻璃固化体结构与化学稳定性显示文摘用溶解速率法(dissolutionrate)、试样坚固法(productconsistencytest)和蒸汽水化侵蚀法(vaporhydrationtest)对高放射性核废料(HLW)玻璃固化体的化学稳定性作了全面的测试,并对它们进行傅立叶变换红外光谱(FTIR)和X射线衍射(XRD)测试.FTIR分析表明,在较高的HLW包容量的玻璃固化体中,含有较少的容易被水化(PO3)1-的长链单元,因此它们具有优良的化学稳定性.XRD分析表明,玻璃固化体中分离的(P2O7)4-和(PO4)3-阴离子团被金属离子Fe3+,Cr3+等所连接,形成O—Me—O—P键,不仅提高了玻璃的抗析晶的能力,而且也大大地提高了化学稳定性.这些高包容量的玻璃固化体的原子比O/(Si+P)为3.7~4.1,从结构上也印证了HLW包容量达70%和75%(质量分数)的玻璃固化体会具有卓越的化学稳定性. | 黄文旵 周萘 Day Delbert E Ray Chandra S | 2005 | 同济大学学报(自然科学版)2005，33，5： | 4 |
| 5 | Effect of fluence and ambient environment on the surface and structural modification of femtosecond laser irradiated Ti显示文摘Under certain conditions, ultrafast pulsed laser interaction with matter leads to the formation of self-organized conical as well as periodic surface structures(commonly reffered to as, laser induced periodic surface structures, LIPSS). The purpose of the present investigations is to explore the effect of fsec laser fluence and ambient environments(Vacuum &O_2) on the formation of LIPSS and conical structures on the Ti surface. The surface morphology was investigated by scanning electron microscope(SEM). The ablation threshold with single and multiple(N = 100) shots and the existence of an incubation effect was demonstrated by SEM investigations for both the vacuum and the O_2 environment. The phase analysis and chemical composition of the exposed targets were performed by x-ray diffraction(XRD) and energy dispersive x-ray spectroscopy(EDS), respectively. SEM investigations reveal the formation of LIPSS(nano & micro). FFT d-spacing calculations illustrate the dependence of periodicity on the fluence and ambient environment. The periodicity of nano-scale LIPSS is higher in the case of irradiation under vacuum conditions as compared to O_2. Furthermore, the O2 environment reduces the ablation threshold. XRD data reveal that for the O_2 environment, new phases(oxides of Ti) are formed. EDS analysis exhibits that after irradiation under vacuum conditions, the percentage of impurity element(Al) is reduced. The irradiation in the O_2 environment results in 15% atomic diffusion of oxygen. | Umm-i-Kalsoom Shazia Bashir Nisar Ali M Shahid Rafique Wolfgang Husinsky Chandra S R Nathala Sergey V Makarov Narjis Begum | 2016 | Chinese Physics B2016，25，1： | 2 |
