| 1 | Insulin resistance in H pylori infection and its association with oxidative stress显示文摘AIM: To determine the insulin resistance (IR) and oxidative status in H pylori infection and to find out if there is any relationship between these parameters and insulin resistance. METHODS: Fifty-five H pylori positive and 48 H pylori negative patients were enrolled. The homeostasis model assessment (HOMA) was used to assess insulin resistance. Serum total antioxidant capacity (TAC), total oxidant status (TOS) and oxidative stress index (OSI) were determined in all subjects. RESULTS: The total antioxidant capacity was significantly lower in H pylori positive group than in H pylori negative group (1.36 ± 0.33 and 1.70 ± 0.50, respectively; P < 0.001), while the total oxidant status and oxidative stress index were significantly higher in H pylori positive group than in H pylori negative group (6.79 ± 3.40 and 5.08 ± 0.95, and 5.42 ± 3.40 and 3.10 ± 0.92, respectively; P < 0.001). Insulin resistance was significantly higher in H pylori positive group than in H pylori negative group (6.92 ± 3.86 and 3.61 ± 1.67, res- pectively; P < 0.001). Insulin resistance was found to be significantly correlated with total antioxidant capacity (r = -0.251, P < 0.05), total oxidant status (r = 0.365, P < 0.05), and oxidative stress index (r = 0.267, P < 0.05). CONCLUSION: Insulin resistance seems to be associated with increased oxidative stress in H pylori infection. Further studies are needed to clarify the mechanisms underlying this association and elucidate the effectof adding antioxidant vitamins to H pylori eradication therapy on insulin resistance during H pylori infection. | Mehmet Aslan Mehmet Horoz Yasar Nazligul Cengiz Bolukbas F Fusun Bolukbas Sahbettin Selek Hakim Celik Ozcan Erel | 2006 | World Journal of Gastroenterology2006，12，42： | 15 |
| 2 | Handheld high-throughput plasmonic biosensor using computational on-chip imaging显示文摘We demonstrate a handheld on-chip biosensing technology that employs plasmonic microarrays coupled with a lens-free computational imaging system towards multiplexed and high-throughput screening of biomolecular interactions for point-of-care applications and resource-limited settings.This lightweight and field-portable biosensing device,weighing 60 g and 7.5 cm tall,utilizes a compact optoelectronic sensor array to record the diffraction patterns of plasmonic nanostructures under uniform illumination by a single-light emitting diode tuned to the plasmonic mode of the nanoapertures.Employing a sensitive plasmonic array design that is combined with lens-free computational imaging,we demonstrate label-free and quantitative detection of biomolecules with a protein layer thickness down to 3 nm.Integrating large-scale plasmonic microarrays,our on-chip imaging platform enables simultaneous detection of protein mono-and bilayers on the same platform over a wide range of biomolecule concentrations.In this handheld device,we also employ an iterative phase retrieval-based image reconstruction method,which offers the ability to digitally image a highly multiplexed array of sensors on the same plasmonic chip,making this approach especially suitable for high-throughput diagnostic applications in field settings. | Arif E Cetin Ahmet F Coskun Betty C Galarreta Min Huang David Herman Aydogan Ozcan Hatice Altug | 2014 | Light(Science & Applications)2014，3，1： | 6 |
| 3 | 血压晨峰、血尿酸与高血压患者心血管预后间关系显示文摘高血压为高发慢性病之一,将增加心血管疾病的不良预后,尤以血压晨峰(MBPS)危害更大,亦为其重要危险因素之一。然而既往关于MBPS与血尿酸(SUA)间关系,以及两者与心血管疾病不利预后间关系均不清楚,现就此进行分析。受测对象为921例高血压患者,女性45.6%,男性54.4%,且160例(17.4%)伴有糖尿病,204例(22.2%)吸烟,372例(40.4%)服用降压药,8例(8.7%)伴冠心病史,14例(1.5%)伴外周动脉病,10例(1.09%)伴主动脉瘤。 | Turak O Afsar B Ozcan F 袁志敏 | 2015 | 心血管病学进展2015，36，4： | 2 |
