In recent years, energy crisis and environmental issues such as greenhouse effect, global warming, etc. has roused peoples' concern. Biodiesel, as renewable energy, has attracted much attention to deal with such problems. This work studied the lipid production by Rhodotorula glutinis with undetoxified corncob hydrolysate. The results indicated that R.(More)
Bolting is an important agronomic trait in Brassica rapa crops due to its effect on yield and quality. Bolting is a complicated trait regulated by multiple genes that is highly influenced by the environment. Defining the chromosomal region(s) involved and clarifying the genetic interactions is important for improving the effectiveness of marker-assisted(More)
A new air exchange rate (AER) monitoring method using continuous CO2 sensors was developed and validated through both laboratory experiments and field studies. Controlled laboratory simulation tests were conducted in a 1-m3 environmental chamber at different AERs (0.1-10.0 hr(-1)). AERs were determined using the decay method based on box model assumptions.(More)
Leaves are vital plant organs, and a high level of variation in leaf shape, including the leaf lobes, is present in Brassica rapa. Based on a previously-constructed linkage map, QTL analysis of the leaf lobes was performed using the scores from an F2 population during the spring of 2010, and scores from an F2:3 family in the autumn of 2010, respectively. A(More)
Biofilms are surface-attached colonies of bacteria embedded in an extracellular polymeric substance (EPS). Inside the eukaryotic hosts, bacterial biofilms interact with the host cells through signaling factors (SFs). These signaling processes play important roles in the interaction between bacteria and host cells and the outcome of infections and symbiosis.(More)
Chromatin modification is pivotal to the epithelial-mesenchymal transition (EMT), which confers potent metastatic potential to cancer cells. Here, we report a role for the chromatin remodeling factor lymphoid-specific helicase (LSH) in nasopharyngeal carcinoma (NPC), a prevalent cancer in China. LSH expression was increased in NPC, where it was controlled(More)
The whitefly, Bemisia tabaci, has developed a high level of resistance to thiamethoxam, a second generation neonicotinoid insecticide that has been widely used to control this pest. In this study, we assessed the level of cross-resistance, the activities of detoxifying enzymes, and the expression profiles of 23 glutathione S-transferase (GST) genes in a(More)
In this work, a new method has been proposed to simultaneously determine the trace amount of malachite green and crystal violet from aqueous solution by spectrophotometry after cloud point extraction (CPE) using partial least squares regression. The optimal extraction and operating conditions, such as pH, reagents concentration and effect of time and(More)
The sweetpotato whitefly Bemisia tabaci is a highly destructive agricultural and ornamental crop pest. It damages host plants through both phloem feeding and vectoring plant pathogens. Introductions of B. tabaci are difficult to quarantine and eradicate because of its high reproductive rates, broad host plant range, and insecticide resistance. A total of(More)
Many studies have focused on the relationships of particulate matter between indoor, outdoor and personal exposure; however, considerable uncertainties remain regarding the portion of indoor particles and personal exposure of ambient origin. As part of the Particle Exposure Assessment for Community Elderly (PEACE) study in Tianjin, China, we have further(More)
