The purpose of this study was to improve our understanding of the molecular epidemiology of human Blastocystis, focusing on 239 randomly selected individuals in a single village in Yunnan province, China. Emphasis was placed on the relative frequency of different Blastocystis subtypes and underlying risk factors. We used a cross-sectional study design, by(More)
BACKGROUND Strongyloides stercoralis is a neglected soil-transmitted helminth species, and there is a lack of parasitologic and epidemiologic data pertaining to this parasite in China and elsewhere. We studied the local occurrence of S. stercoralis in a village in Yunnan province, China, and comparatively assessed the performance of different diagnostic(More)
Intestinal multiparasitism, the accuracy of different diagnostic techniques, and the influence of sampling effort were studied among 215 individuals in a Bulang village, Yunnan province, People's Republic of China. Behavioral, demographic, and socioeconomic data were obtained by questionnaire. Multiple stool specimens were examined by the Kato-Katz, Koga(More)
Chronic soil-transmitted helminth (STH) infections have been associated with reduced physical fitness, but available evidence is limited. The aim of this cross-sectional survey was to assess the feasibility of measuring children's physical fitness and to relate it to STH infections. Our study was carried out among school-aged children of the Bulang ethnic(More)
OBJECTIVE To reveal the distribution and composition of malaria-transmitting vectors on the western part of China-Myanmar border. METHODS An entomological survey of malaria vectors was carried out in six villages of Yingjiang County and Xidong County on China-Myanmar border between August and September, 2008. Mosquitoes in human dwellings and cattle sheds(More)
OBJECTIVE To identify the species of Anopheles maculatus complex in malaria endemic area Motuo County, Linzhi Prefecture, Tibet Autonomous Region. METHODS 5190 adult mosquitoes were morphologically identified as An. maculatus complex, and 575 were randomly selected to extract DNA by phenol-chloroform method. According to the rDNA ITS2 variations of An.(More)
The bounds for the Z-spectral radius of nonsingular H-tensor, the upper and lower bounds for the minimum H-eigenvalue of nonsingular (strong) M-tensor are studied in this paper. Sharper bounds than known bounds are obtained. Numerical examples illustrate that our bounds give tighter bounds. Dedicated to Professor Ravindra B. Bapat on the occasion of his(More)
OBJECTIVE To investigate the effect of the anti-platelet effect of aspirin plus clopidogrel on off-pump coronary artery bypass (OPCAB) grafting and the possible side effects of such therapy. METHODS Sixty patients who underwent standard OPCAB were randomized immediately after surgery in two groups: the aspirin alone group of 30 patients who received(More)
The measurements of 31 kinds of VOCs in the ambient air of a site were carried out in the downtown of Guangzhou by online method from November 5, 2009 to November 9, 2009. The ambient level and composition characteristics, temporal variation characteristics, sources identification, and chemical reactivity of VOCs were studied, and the health risk of VOCs in(More)
