To investigate the cognition of medical professionals when following screening guidelines for colorectal cancer (CRC) and barriers to CRC screening. Between February 2012 and December 2012, an anonymous survey with 19-questions based on several CRC screening guidelines was randomly administered to gastroenterologists, oncologists, general surgeons, and(More)
Members of the family Anelloviridae are emerging circular DNA viruses infecting many species of vertebrates including pigs. To date, members of two distinct genera, Iotatorquevirus, including torque teno sus virus 1a and torque teno sus virus 1b (TTSuV1a and TTSuV1b), and Kappatorquevirus, including torque teno sus virus k2a and torque teno sus virus k2b(More)
For the worldwide pig industries, porcine circovirus type 2 (PCV2) is an economically important pathogen. At present, the prevalence of PCV2 is common in Chinese swine herds. However, there is little information on PCV2 prevalence in non-porcine animals in China, such as bovids. Therefore, the goal of this study is to obtain the firsthand prevalence data of(More)
The integrin α6 subunit is part of the integrin α6β1 and α6β4 complexes, which are known to mediate the invasion of carcinoma cells. However, the precise role of integrin α6 in intrahepatic cholangiocarcinoma (ICC) has not yet been addressed. Twenty cases of ICCs and matched nontumor samples were used to analyze integrin α6 expression by(More)
A compound of flavonol-based biosurfactant, as C(8)-substituted alkylaminomethyl rutin (DAMR) for a potential pharmaceutical or agrochemical use, was prepared experimentally. The surface behavior of DAMR and its mixture with lecithin from soybean (SL) had been studied. DAMR, regarded as a pseudo-amphoteric character, exhibits both liquid-condensed (LC) and(More)
Colorectal cancer (CRC) is considered to be a main cause of malignancy-related death in the world (Parkin, 2001), and in China (Sung et al., 2005). It is known that the high risk population of CRC includes those with continuously positive fecal occult blood test (FOBT), with relatives of CRC or other cancer history, and with a history of intestinal adenoma,(More)
A real time investigation of chemical reaction process of quercetin with various concentrations of sodium hydroxide was performed by using an intensified spectroscopic detector ICCD. The time resolved UV-Vis absorption spectra of 5 x 10(-5) mol x L(-1) quercetin respectively reacting with sodium hydroxide at concentrations of 2, 0.2, 0.1, 0.04 and 0.02 mol(More)
BACKGROUND Pseudoachalasia is a rare disorder whose presentation strongly resembles idiopathic achalasia. CASE PRESENTATION Here, we present a case of a 42-year-old female patient with esophageal leiomyoma who was initially diagnosed with achalasia. On endoscopical investigation, however, it became apparent that she had pseudoachalasia as consequence of a(More)
With a deuterium light source was used to provide the continuous light, the time resolved UV-Vis absorption spectra in the synthetic process of quercetin complex with Al3+ were measured by using an intensified ICCD spectroscopic detector. The measuing system was controlled synchronously by using a digital delay generator DG535. A total of 50 spectra with(More)
