Exposure to disinfection by-products（DBP） such as trihalomethanes（THm） in swimming pools has been linked to adverse health effects in humans, but their biological mechanisms are unclear. We evaluated short-term changes in blood gene expression of adult recreational swimmers after swimming in a chlorinated pool. Volunteers swam 40 min in an indoor chlorinated pool. Blood samples were drawn and four THm（chloroform,bromodichloromethane, dibromochloromethane and bromoform） were measured in exhaled breath before and after swimming. Intensity of physical activity was measured as metabolic equivalents（mETs）. Gene expression in whole blood m RNA was evaluated using Illumina Human HT-12v3 Expression-Bead Chip. Linear mixed models were used to evaluate the relationship between gene expression changes and THm exposure. Thirty-seven before-after pairs were analyzed. The median increase from baseline to after swimming were： 0.7 to 2.3 for mET, and 1.4 to 7.1 μg/m^3 for exhaled total THm（sum of the four THm）.Exhaled THm increased on average 0.94 μg/m^3 per 1 mET. While 1643 probes were differentially expressed post-exposure. Of them, 189 were also associated with exhaled levels of individual/total THm or mET after False Discovery Rate. The observed associations with the exhaled THm were low to moderate（Log-fold change range：-0.17 to 0.15）. In conclusion, we identified short-term gene expression changes associated with swimming in a pool that were minor in magnitude and their biological meaning was unspecific. The high collinearity between exhaled THm levels and intensity of physical activity precluded mutually adjusted models with both covariates. These exploratory results should be validated in future studies.

A History of Fischer-Tropsch Wax Upgrading at BP-from Catalyst Screening Studies to Full Scale Demonstration in Alaska

引用

Journal of Natural Gas Chemistry 2006年第1期15卷 1-10页

作者： John P. Collins Joep J. H. m. font Freide Barry Nay BP Exploration America Inc. BP Exploration Operating Company

Conversion of Fischer-Tropsch wax into high quality synthetic crude or finished transportation fuels such as premium diesel has been studied over the past 15 years within BP. Catalyst screening and selection was carried out in dedicated micro-reactors and pilot plants, whose designs are critical to the performance selection. Variation in catalyst composition and defining the gas to oil feed ratios with the operating temperature are a few of the parameters studied. Product selection and maximizing diesel yield combined with stability （catalyst life） were the ultimate drivers. The selected catalyst was then tested under commercial conditions in a dedicated 300 barrel per day demonstration plant. The products were also tested in engines to assess their combustion characteristics.

Borderline resectable pancreatic cancer: Definitions and management

引用

World Journal of Gastroenterology 2014年第31期20卷 10740-10751页

作者： Nicole E Lopez cristina Prendergast Andrew m Lowy Division of Surgical Oncology Department of Surgery Moores Cancer Center University of California San Diego

Pancreatic cancer is the fourth leading cause of cancer death in the United States. While surgical resection remains the only curative option, more than 80% of patients present with unresectable disease. Unfortunately, even among those who undergo resection, the reported median survival is 15-23 mo, with a 5-year survival of approximately 20%. Disappointingly, over the past several decades, despite improvements in diagnostic imaging, surgical technique and chemotherapeutic options, only modest improvements in survival have been realized. Nevertheless, it remains clear that surgical resection is a prerequisite for achieving longterm survival and cure. There is now emerging consensus that a subgroup of patients, previously considered poor candidates for resection because of the relationship of their primary tumor to surrounding vasculature, may benefit from resection, particularly when preceded by neoadjuvant therapy. This stage of disease, termed borderline resectable pancreatic cancer, has become of increasing interest and is now the focus of a multiinstitutional clinical trial. Here we outline the history, progress, current treatment recommendations, and future directions for research in borderline resectable pancreatic cancer.

A （p, q）-graph G is called super edge-magic if there exists a bijective function f ： V（G） U E（G） →{1, 2 p＋q} such that f（u）＋ f（v）＋f（uv） is a constant for each uv C E（G） and f（Y（G）） = {1,2,...,p}. In this paper, we introduce the concept of strong super edge-magic labeling as a particular class of super edge-magic labelings and we use such labelings in order to show that the number of super edge-magic labelings of an odd union of path-like trees （mT）, all of them of the same order, grows at least exponentially with m.
