Eosinophilic cholangitis treatment with budesonide

引用

World Journal of Hepatology 2017年第36期9卷 1385-1388页

作者： Marianne Anastasia De Roza chee Hooi lim Department of Gastroenterology and Hepatology Singapore General HospitalSingapore 169856Singapore

Eosinophilic cholangitis is a rare cause of deranged obstructive liver function tests. It has been described as a great mimicker for malignant biliary strictures and bile duct obstruction. There are only case reports available on treatment experience for eosinophilic cholangitis. A large proportion of patients present with biliary strictures for which they have undergone surgery or endoscopic treatment and a small proportion was given systemic corticosteroid. We share our treatment experience using budesonide which has fewer systemic side effects to prednisolone and avoids invasive management.

Short carbon fiber(SCF)reinforced epoxy composites with different SCF contents were developed to investigate their tribological *** friction coefficient and wear of the epoxy composites slid in a circular path against a steel pin inclined at 45°to a vertical axis and a steel ball significantly decreased with increased SCF content due to the solid lubricating effect of SCFs along with the improved mechanical strength of the *** scanning electron microscope(SEM)observation showed that the epoxy composites had less sensitive to surface fatigue caused by the repeated sliding of the counterparts than the *** tribological results clearly showed that the incorporation of SCFs was an effective way to improve the tribological properties of the epoxy composites.

High-Resolution Infrared-Vacuum Ultraviolet Photoion and Pulsed Field Ionization-Photoelectron Methods for Spectroscopic Studies of Neutrals and Cations

引用

Chinese Journal of Chemical Physics 2008年第3期21卷 193-201页

作者： Xi Xing Beth Reed Mi Kyung Bahng peng Wang Hin Koo Woo Sun Jong Baek chee Shing Lain Cheuk Yiu Ng Department of Chemistry University of California Davis Davis California 95616 USA

We show that by scanning the frequency of a single mode infrared （IR） optical parametric oscillator （IR- OPO） laser to excite the molecular species of interest and fixing the frequency of a vacuum ultraviolet （VUV） laser to photoionize the IR excited species, high-resolution IR spectra of polyatomic neutrals can be obtained with high sensitivity. The fact that this IR-VUV-photoion （IR-VUV-PI） method is based on VUV photoionization probe, and thus, allows the identification of the neutral IR absorber, makes it applicable for IR spectroscopy measurements of isotopemers, radicals, and clusters, which usually exist as impure samples. The highly resolved IR-VUV-PI measurements achieved using the single mode IR-OPO laser have made possible the selection of single rovibrational states of CH3X （X=Br and I）, C2H4, and C3H4 for VUV-pulsed field ionization-photoelectron （VUV-PFI-PE） measurements, resulting in rovibrationally resolved photoelectron spectra for these polyatomic molecules. These experiments show that the signal- to-noise ratios of the IR-VUV-PI and IR-VUV-PFI-PE spectra obtained by employing the high-resolution IR-OPO laser are significantly higher than those observed in previous IR-VUV-PI and IR-VUV-PFI-PE studies using a low-resolution IR-OPO laser. Further improvement in sensitivity of IR-VUV-PI and IR- VUV-PFI-PE measurements by using the collinear arrangement of IR-VUV lasers and molecular beam is discussed.
