PURPOSE To compare posterior corneal elevation (PCE) changes and corneal biomechanical changes post fematosecond laser-assisted laser in situ keratomileusis (FS-LASIK) and small incision lenticule extraction (SMILE) procedures using the Pentacam system and the Ocular Response Analyzer (ORA). DESIGN Retrospective observational case series study. METHOD(More)
PURPOSE To conduct in vivo measurements of the bulbar conjunctiva epithelial, stromal, and total thicknesses in healthy Chinese subjects using optical coherence tomography (OCT) and to compare the conjunctival thickness differences between sex and age. METHODS From January to July 2012, healthy Chinese subjects were recruited to undergo a Cirrus HD-OCT(More)
In the present study, we examined the mechanisms of oxaliplatin-induced drug resistance in human colorectal cancer cell lines HT29 and HCT116. Our results demonstrate a significant autophagy expression in CRC cells after an oxaliplatin treatment. Administration of oxaliplatin to human CRC cells significantly enhanced the expression of HMGB1, which regulated(More)
A novel second order sigma delta modulator (SDM) with 5-bit quantizer has been proposed with simplified DAC arrays, high-order truncation noise shaping for increased tolerance to analog imperfections, and extended dynamic range for a maximum input signal swing of up to -0.45 dBFS. With truncation filter and pseudo SDM in the DSP, the truncation and(More)
Proteins in the aqueous humor (AH) are important in the induction of cataract development. The identification of cataract-associated proteins assists in identifying patients and predisposed to the condition and improve treatment efficacy. Proteomics analysis has previously been used for identifying protein markers associated with eye diseases; however, few(More)
approved: Gábor C. Temes Delta-Sigma () analog-to-digital converters (ADCs) are widely used in wireless transceivers. Recently, continuous-time (CT) ADCs gain growing interest in wireless applications for their lower power consumption and wider input bandwidth as compared with the discrete-time (DT) counterparts. In this thesis, a wideband low-power CT(More)
The power efficiency of pipelined and cyclic ADCs can be improved significantly by judicious choice of the interstage gain. Previous investigations by the authors have shown the possibility of using a novel technique known as the generalized radix design approach to attain the goal of optimal power-speed tradeoffs in this class of ADCs. In order to test the(More)
Anisic acid, the precursor of a variety of food flavors and industrial raw materials, can be bioconversed from anethole which extracted from star anise fruits. WGB31 strain with anisic acid molar production rate of 10.25% was isolated and identified as Burkholderia sp. Three significant influential factors, namely, glucose concentration, initial pH value,(More)
