| 1 | Gallbladder function and dynamics of bile flow in asymptomatic gallstone disease显示文摘AIM:To investigate the effects of gallbladder stones on motor functions of the gallbladder and the dynamics of bile flow in asymptomatic gallstone disease.METHODS:Quantitative hepatobiliary scintigraphy was performed to detect the parameters of gallbladder motor function [gallbladder ejection fraction(GBEF),gallbladder visualization time(GBVT),gallbladder time to peak activity(GBTmax),gallbladder half emptying time(GBT1/2),and transit time of bile to duodenum(TTBD)] in 24 patients with asymptomatic cholelithiasis who were diagnosed incidentally during routine abdominal ultrasonographic examination and 20 healthy subjects with normal gallbladder.RESULTS:Even though there was no significant difference in the clinical and laboratory parameters between the patient and control groups,all parameters of gallbladder function except TTBD were found to differ significantly between the two groups.GBEF in the patient group was decreased(P=0.000) and GBVT,GBTmax,GBT1/2 in the patient group were longer(P=0.000,P=0.015,P=0.001,respectively).CONCLUSION:Our results showed that even if there were not any clinical and laboratory findings,gallbladder filling and emptying could be impaired in patients with gallstone disease. | Sevim Süreyya eri Feride Meltem zbek Celal eri Bahattin Baykal Hasan Erol Eroglu Zeynep Baykal Mustafa Yildiz Semahat Saglam Ahmet Yesildag | 2009 | World Journal of Gastroenterology2009，15，22： | 8 |
| 2 | 西地那非能改善慢性肾功能衰竭大鼠的勃起功能显示文摘勃起功能障碍(ED)和慢性肾衰竭(CRF)之间的关系已在几个研究中被报道。本研究旨在探讨长期使用西地那非是否能增强CRF诱导大鼠的勃起能力。此外,我们评估了该治疗对某些分子的影响,这些分子被认为在勃起生理学及CRF相关的ED中起关键作用。研究分三组:(1)年龄配对的对照组,(2)CRF诱导的大鼠模型组,(3)CRF诱导大鼠给予西地那非慢性给药组((5 mg /kg口服6周[CRF诱导后6周开始治疗])。 3个月时,所有的动物进行海绵体神经刺激(CNS)来评估勃起功能。在所有大鼠组进行,阴茎组织晚期糖化终产物(AGE的) / 5-羟甲基-2-糠醛,丙二醛(MDA),cGMP(ELISA),诱导型一氧化氮合酶(iNOS)和神经元型NOS(nNOS的)(Western印迹)分析。CRF诱导大鼠与对照组相比,勃起功能有显著降低(P 〈0.05)。CRF诱导大鼠西地那非治疗组(第3组),海绵体内压(ICP)和曲线下面积的
增加量,大于CRF诱导大鼠组(第2组)。此外,西地那非治疗下调了AGE,MDA和iNOS的水平,同时保持了CRF诱导阴茎组织的nNOS和cGMP含量。西地那非治疗组AGE,MDA,iNOS的下降和nNOS,cGMP水平的增加,增加了ICP和海绵体神经刺激(CNS)的总ICP,使得CRF诱导大鼠阴茎勃起功能得到改善。本研究的结果表明慢性西地那非给药对CRF诱导大鼠的勃起功能有治疗效果。 | Nilgun Gurbuz Arif Kol Tumay Ipekci Erhan Ates Asli Baykal Mustafa F Usta | 2015 | Asian Journal of Andrology2015，17，5： | 3 |
| 3 | Dielectric and microstructural properties of YAG:Dy^(3+) ceramics显示文摘Yttrium aluminium garnet(Y_3 Al_5 O_(12):YAG) singly doped with Dy3+ at different concentrations was prepared by solid state reactions using repeated heating cycles over the temperature range of 1300-1600 ℃. X-ray powder diffraction analysis confirms the presence of a well-crystallized YAG perovskite phase with cubic structure(by Rietveld refinement). The rare earth dopant is successfully integrated into the YAG host lattice without any major changes in the original structure. The temperature dependence,up to 250 ℃, of the conductivity, dielectric constant, dielectric loss, and loss tangent, at various frequencies of up to 5.0 MHz for undoped and doped crystals is compared to understand the electrical and structural characteristics. The experimental results reveal that Dy3+ dopants in YAG crystal significantly influence the conductivity, dielectric constant, and lossy mechanisms, which is probably due to the 3 d-AI ions and 4 f-Dy ions incorporated at different positions of both tetrahedral and octahedral symmetries in YAG:xDy3+ ceramics. | Munirah Abdullah Almessiere Bayram Unal Abdulhadi Baykal | 2018 | Journal of Rare Earths2018，36，12： | 2 |
| 4 | Development of an Amperometric Hydrogen Peroxide Biosensor based on the Immobilization of Horseradish Peroxidase onto Nickel Ferrite Nanoparticle-Chitosan Composite显示文摘Nickel ferrite(NiFe_2O_4) nanoparticles have been dispersed in chitosan solution in order to fab ricate nanocomposite films.Horseradish peroxidase(HRP) has been immobilized onto this chitosan NiFe_2O_4 nanocomposite film via physical adsorption.The size of the NiFe_2O_4 nanoparticles has been estimated us ing X ray diffraction pattern and scanning electron microscopy(SEM) to be 40±9 nm.The chitosan NiFe_2O_4 nanocomposite film and HRP/chitosan NiFe_2O_4 bioelectrode have been characterized using SEM technique.The HRP/chitosan NiFe_2O_4 nanocomposite bioelectrode has a response time of 4 s,linearity as 0.3 to 12 m M of H2O2,sensitivity as 22 n A/m M.The effects of p H and the temperature of the immobilized HRP electrode have also been studied. | Furkan Yalcner Emre Cevik Mehmet Senel Abdulhadi Baykal | 2011 | Nano-Micro Letters2011，3，2： | 2 |
