Mixed Connective Tissue Disease Complicated by Retinal Microvasculopathy and Its Relationship with Fragile-X Syndrome

引用

Open Journal of Ophthalmology 2013年第3期3卷 70-72页

Purpose: To report an unusual case of retinal microvasculopathy secondary to mixed connective tissue disease (MCTD) on a background history of fragile-X syndrome (FXS). Methods: Case report and literature review. Results: A cotton wool spot was discovered in a 29-year-old female who presented with an ischaemic digit secondary to Raynaud’s phenomenon. She also has a background history of MCTD and FXS. Fundus examination and automated perimetry findings were normal. Magnet resonance imaging and computed tomography aortogram did not demonstrate any evidence of vasculitis in the head and neck. She was tested positively for U1-ribonuclear peptide. Interestingly, the re-distribution of Fragile-X related gene 1 has been suggested to trigger autoimmune responses in experiments. This finding makes the case peculiar as it suggests an alternate explanation for this patient’s clinical findings. Conclusion: Retinal vasculopathy is a rare complication of MCTD. The background history of FXS potentially highlights an alternate autoimmune pathogenetic mechanism.

All-fiber, wavelength-tunable ultrafast praseodymium fiber laser

引用

Chinese Optics Letters 2018年第12期16卷 56-60页

作者： H.Ahmad S.N.aidit S.I.ooi Z.C.Tiu Photonics Research Centre University of Malaya Department of Physics Faculty of Science and TechnologyAirlangga University

The interest in tunable ultrafast fiber lasers operating in the 1.3 μm region has seen a significant increase due to rising demands for bandwidth as well as the zero-dispersion characteristic of silica fibers in this wavelength region. In this work, a tunable mode-locked praseodymium-doped fluoride fiber(PDFF) laser using single-walled carbon nanotubes as a saturable absorber is demonstrated. The mode-locked pulses are generated at a central wavelength of 1302 nm with a pulse repetition rate of 5.92 MHz and pulse width of 1.13 ps. The tunability of the mode-locked PDFF laser covers a tuning range of 11 nm.

Nonlinear optics on silicon-rich nitride--a high nonlinear figure of merit CMOS platform[Invited]

引用

Photonics Research 2018年第5期6卷 I0075-I0091页

CMOS platforms with a high nonlinear figure of merit are highly sought after for high photonic quantum efficiencies, enabling functionalities not possible from purely linear effects and ease of integration with CMOS electronics. Silicon-based platforms have been prolific amongst the suite of advanced nonlinear optical signal processes demonstrated to date. These include crystalline silicon, amorphous silicon, Hydex glass, and stoichio- metric silicon nitride. Residing between stoichiometric silicon nitride and amorphous silicon in composition, silicon-rich nitride films of various formulations have emerged recently as promising nonlinear platforms for high nonlinear figure of merit nonlinear optics. Silicon-rich nitride films are compositionally engineered to create bandgaps that are sufficiently large to eliminate two-photon absorption at telecommunications wavelengths while enabling much larger nonlinear waveguide parameters （5x-500x） than those in stoichiometric silicon uitride. This paper reviews recent developments in the field of nonlinear optics using silicon-rich nitride platforms, as well as the outlook and future opportunities in this burgeoning field.

湘味面粉熟食的冬季生产用油大多是一级大豆油,但是其用油成本较高、易哈败、产品货架期较短。本试验在大豆油中加入适量超级棕榈液油和抑晶剂制成调合油,用于生产冬季湘味面粉熟食中,分析比较各自熟食产品的品质及其在0～5℃冬季气温条件下的贮藏稳定性。结果表明,分别利用优化配方调和油和一级大豆油生产的湘味面粉熟食在品质上没有明显差异,均达到DB43/160.8———2009标准的质量要求;而且,调和油熟食的氧化稳定性优于大豆油熟食。说明利用超级棕榈液油部分取代大豆油来生产湘味面粉熟食,不但可以降低生产成本,还可以延长产品货架期。

Chemical Enhancement of the Surface Enhanced Raman Scattering Signals of Anilines via Their <i>Ortho</i>-Substituents

引用

Optics and Photonics Journal 2013年第5期3卷 13-23页

作者： Rachel A. Davies Ngee S. Chong Beng Guat ooi Department of Chemistry Middle Tennessee State University Murfreesboro USA

While Raman spectroscopy is a useful method for analyzing many organic compounds, it is limited by relatively low sensitivity. Therefore, Surface Enhanced Raman Spectroscopy (SERS) based on the adsorption of organic analytes onto gold or silver nanostructures has been used to enhance the signal of chemicals presented at very low concentrations. Although the plasmonic effect of SERS has been shown to play a large role in signal enhancement, the significance of the chemical effect due to the analyte chemisorption on the gold or silver surface is less well understood. In this study, the role of aniline substituents is examined by probing the SERS intensities of various anilines in silver and gold colloids using a Raman spectrometer with an excitation wavelength of 785 nm. The SERS enhancement factors and detection limits for aniline and its mono- and di-substituted ortho derivatives are determined and compared. Both the steric requirements of chemisorption and the inductive effects of electron-withdrawal due to the substituents affect the signal intensities of various vibrational modes of the amino group and the aromatic ring. The degree of enhancement is also related to the methods for preparing the silver and gold colloids, which are characterized by probing the nanoparticle morphology and its degree of aggregation using transmission electron microscopy (TEM).

aiM: To determine the complex of AST and immunoglobulin and to investigate its clinical significance in patients with liver ***: The complex of AST and immunoglobulin was determined by encounter immunoelectrophoresis and its clinical significance was investigated in 128 patients with liver ***: AST was bound to immunoglobulin of antiimmunoglobulin A (IgA) class, but any binding to antiimmunoglobulin G and anti-immunoglobulin M classes was not observed. Although the incidence of ASTimmunoglobulin complex was 41.8% in chronic hepatitis (CH), the incidences in liver cirrhosis and hepatocellular carcinoma were 62.2 and 90.0%, respectively. In alcoholic liver disease with high level of serum IgA, the incidence of the complex was 66.7%, which was higher than that in CH. The ratio of binding to lambda-chain of IgA was higher than that to kappa-chain of IgA. The serum level of IgA and the ratio of AST/alanine aminotransferase (ALT) were significantly higher in patients with AST-IgA complex than in those without ***: These results suggest that AST-IgA complex in patients with progressive liver diseases and alcoholic liver injury can lead to elevation of the ratio of AST/ALT.
