Although the zinc finger transcription factor Krüppel-like factor 4 (KLF4) has been shown to be a negative regulator of cell proliferation, the mechanisms underlying the posttranslational modification of KLF4, especially at the level of protein degradation, are poorly understood. Here, we show that KLF4 protein levels in quiescent cells were high, but(More)
A multi-chip system was built to provide experimental verification of a correlation-based digital algorithm, which acquires and corrects all element errors in the internal DAC of a multi-bit delta-sigma ADC. The proposed correction method does not rely on noise shaping, and hence it remains fully effective even for very low oversampling ratios (OSRs).(More)
To assess the correlation between penile hypersensitivity and premature ejaculation (PE), a total of 420 consecutive subjects attending our andrologic clinic for suspected PE were enrolled. The entire cohort was asked to complete the self-report intravaginal ejaculation latency time (IELT) by stopwatch. According to the IELT, the subjects were classified(More)
OBJECTIVE To investigate the association of polymorphisms of DNA double-strand break repair gene XRCC4 and chromosomal damage levels in peripheral blood lymphocyte in workers exposed to 1,3-butadien (BD). METHODS 189 BD exposed workers and 83 controls were recruited in this study. Chromosomal damage in peripheral lymphocytes was measured by the(More)
OBJECTIVE To study the status quo of oral professional and technical personnel of Guyuan city, Ningxia. METHODS In consultation with Administrative Department of Public Health, all oral health institutions by age, gender, education, professional, and department in four counties (Longde, Jingyuan, Pengyang and Xiji) and Yuanzhou district in Guyuan City(More)
A method based on on-line solid-phase extraction (SPE) with hydrophobic monolithic column coupled with high performance liquid chromatography-tandem mass spectrometry was developed for the simultaneous determination of five avermectins in bovine liver. A poly(butyl methacrylate-co-ethylene dimethacrylate) monolithic column was used as the sorbent. The(More)
OBJECTIVE To compare the determination ability of four in vitro cytotoxicity assays for acute toxicity of diesel exhaust particulate (DEP) extracts. METHOD The cell viability of cultured 16HBE cells was measured by the MTT assay, the neutral red assay, the lactate dehydrogenase (LDH) leakage assay and the determination of total protein content after 12,(More)
OBJECTIVE To investigate the DNA and chromosome damage in peripheral blood lymphocyte of workers occupationally exposed to 1,3-butadiene (BD). METHODS Personal information including occupational history, age, sex, smoking and drinking status was collected by the questionnaire. Gas chromatography was used to analyze the BD level. One hundred and eighty(More)
Nowadays robot-assisted minimally invasive surgery (MIS) is popular because of numerous benefits to patients. However, the surgical performance evaluation methods have always failed to catch up with the development speed of surgical robot system technology. In this paper, a method `SOE' to evaluate surgeons' robot-assisted MIS operation skill is provided.(More)
