Purpose: Levobupivacaine showed a lower risk of cardiovascular and central nervous system (CNS) toxicity than bupivacaine which is the most popular local anesthetic agent in obstetric practice. The aim of this study was to investigate the clinical efficacy of levobupivacaine compared with hyperbaric bupivacaine for spinal anesthesia for cesarean section. Methods: 60 pregnant women in ASA I - II group scheduled to have elective cesarean operation were allocated into the study. Patients were randomly divided into two groups. The combinations 10 mg levobupivacaine (0.5%) + fentanyl (15 μcg) for Group LF (n = 30) patients, 10 mg hyperbaric bupivacaine (0.5%) + fentanyl (15 μcg) for BF (n = 30) patients were intrathecally administrated a total of 2.3 cc. Sensory and motor block characteristics of the groups were assessed with pinprick and Bromage scale;observed hemodynamic changes and side effects were recorded. Results: The time to reach maximum dermatome for the sensory block, time to regression by two dermatomes and time to regress to T12 dermatome was found to be significantly long in Group BF. It was observed that in Group BF, the evolution of the motor block was faster and lasted longer. Whereas hypotension, bradycardia and nausea were less in Group LF, the need for ephedrine was higher in Group BF (p < 0.05). Conclusion: Since motor block time is shorter, and side effects like hypotension, bradycardia and nausea are less, the combination of levobupivacaine + fentanyl can be a good alternative in cesarean sections.

Nonlinear transverse vibrations of a slightly curved beam carrying a concentrated mass

引用

Acta Mechanica Sinica 2009年第6期25卷 871-882页

作者： E.zkaya M.Sarigül H.boyaci Department of Mechanical Engineering Celal Bayar UniversityMuradiye

In this study, a slightly curved Euler Bernoulli beam carrying a concentrated mass was handled. The beam was resting on an elastic foundation and simply supported at both ends. Effects of the concentrated mass on nonlin- ear vibrations were investigated. Sinusoidal and parabolic type functions were used as curvature functions. Equations of motion have cubic nonlinearities because of elongations during vibrations. Damping and harmonic excitation terms were added to the equations of motion. Method of mul- tiple scales, a perturbation technique, was used for solving integro-differential equation analytically. Natural frequen- cies were calculated exactly for different mass ratios, mass locations, curvature functions, and linear elastic foundation coefficients. Amplitude-phase modulation equations were found by considering primary resonance case. Effects of nonlinear terms on natural frequencies were calculated. Frequency-amplitude and frequency-response graphs were plotted. Finally effects of concentrated mass and chosen curvature function on nonlinear vibrations were investigated.

Quantification and spatial distribution of salicylic acid in film tablets using FT-Raman mapping with multivariate curve resolution

引用

Asian Journal of Pharmaceutical Sciences 2018年第2期13卷 155-162页

In this study, we proposed a rapid and sensitive method for quantification and spatial distribution of salicylic acid in film tablets using FT-Raman spectroscopy with multivariate curve resolution(MCR). For this purpose, the constituents of film tablets were identified by using FT-Raman spectroscopy, and then eight different concentrations of salicylic acid tablets were visualized by Raman mapping. MCR was applied to mapping data to expose the active pharmaceutical ingredients in the presence of other excipients by monitoring distribution maps and combination of FT-Raman mapping with MCR enabled the determination of lower salicylic acid concentrations. In addition, the distribution of major excipient, lactose, was examined in the tablet form. A calibration curve was obtained by plotting the intensity of the Raman signal at 1635 cm^(-1) versus the concentration of salicylic acid and the correlation was found to be linear within the range of 0.5%–3.9% with a correlation coefficient of 0.99. The limit of detection for the technique was determined 0.35%. The ability of the technique to quantify salicylic acid in tablet test samples was also investigated.

自然场景中的物体通常是互相遮挡的,识别这些物体的关键在于确定不同图像区域之间的边缘属于哪一个物体。然而,对于人类视皮层如何编码边缘所有权这个问题,我们知之甚少。在本研究中,我们设计了两个简单有效的视觉刺激作为实验材料。在这些刺激中,对情境信息的微小变动就可以导致边缘所有权的彻底改变。利用功能性核磁共振适应的方法,我们发现次级视皮层对边缘所有权显示了稳定可靠的选择性,而且这种选择性依赖于注意过程。本研究提供了第一个以人类被试为研究对象的实验证据,结果表明次级视皮层是对边缘所有权进行加工的关键区,而且该加工依赖于高级皮层区的调节反馈。
