Anopheles sinensis is an important mosquito vector of Plasmodium vivax, which is the most frequent and widely distributed cause of recurring malaria throughout Asia, and particularly in China, Korea, and Japan. We performed 454 next-generation sequencing and obtained a draft sequence of A. sinensis assembled into scaffolds spanning 220.8 million base pairs.(More)
Pyrethroid insecticides have been extensively used in China and worldwide for public health pest control. Accurate resistance monitoring is essential to guide the rational use of insecticides and resistance management. Here we examined the nucleotide diversity of the para-sodium channel gene, which confers knockdown resistance (kdr) in Culex pipiens pallens(More)
Mosquito control based on chemical insecticides is considered as an important element in the current global strategies for the control of mosquito-borne diseases. Unfortunately, the development of pyrethroid resistance in important vector mosquito species jeopardizes the effectiveness of insecticide-based mosquito control. To date, the mechanisms of(More)
Malaria, dengue fever, and filariasis are three of the most common mosquito-borne diseases worldwide. Malaria and lymphatic filariasis can occur as concomitant human infections while also sharing common mosquito vectors. The overall prevalence and health significance of malaria and filariasis have made them top priorities for global elimination and control(More)
Continuous and excessive application of insecticides has resulted in the rapid development of insecticide resistance in several mosquito species, including Culex pipiens pallens. Previous studies in our laboratory found that arrestin gene expression was higher in the deltamethrin-resistant (DR) strain than in the deltamethrin-susceptible (DS) strain of Cx.(More)
OBJECTIVE To evaluate the relationship between dietary habits, physical activity and cognitive views and the risk of gestational diabetes mellitus (GDM) in Chinese women. DESIGN A cross-sectional study to explore the potential risk factors of GMD through the International Physical Activity Questionnaire, an FFQ and a self-designed structured(More)
The prophenoloxidase subunit A3 (proPOA3) gene was cloned from Culex pipiens pallens, which had an open reading frame of 2061 bp encoding a putative 686 amino acid protein. The deduced amino acid sequence shares 98% with proPOA3 from Culex quinquefasciatus. ProPOA3 is expressed at all developmental stages of C. pipiens pallens. Significant negative(More)
Current vector control programs are largely dependent on pyrethroids, which are the most commonly used and only insecticides recommended by the World Health Organization for insecticide-treated nets (ITNs). However, the rapid spread of pyrethroid resistance worldwide compromises the effectiveness of control programs and threatens public health. Since few(More)
Ribose-phosphate pyrophosphokinase 1 (PRPS1) was identified and isolated as a differentially expressed gene between deltamethrin-susceptible (DS) and deltamethrin-resistant (DR) Culex pipiens pallens and Aedes albopictus C6/36 cell line through microarray and 2D-Gel. An open reading frame of PRPS1 cloned from C. pipiens pallens has 1,011 bp and encodes for(More)
OBJECTIVE To evaluate the relationship between dietary habits and the risk of gestational diabetes mellitus (GDM) in Cantonese women. METHDS This a cross-sectional study included 571 pregnant women who underwent a 75-g oral glucose challenge test at the 24th to 28th gestational week. Food frequency questionnaire (FFQ) was used by three dieticians to(More)
