INTRODUCTION Nasopharyngeal carcinoma is the most common cancer originating from the nasopharynx. OBJECTIVE To study the mechanisms of nasopharyngeal carcinoma, we analyzed GSE12452 microarray data. METHODS GSE12452 was downloaded from the Gene Expression Omnibus database and included 31 nasopharyngeal carcinoma samples and 10 normal nasopharyngeal tissue samples. The differentially express...
Abstract Despite the significant progress made in coalbed methane (CBM) exploration and development recent years, understanding of CBM enrichment mechanisms remains limited. This study aims to elucidate mechanism southern Qinshui Basin, China, by analyzing characteristics global basins building a geological model area. Field analyses are conducted predict sweet spots high abundance production p...
An intramolecular theory of the unusual mass-independent isotope effect for ozone formation and dissociation is described. The experiments include the enrichment factor, its dependence on the ambient pressure, the ratio of the formation rates of symmetric and asymmetric ozone isotopomers, the enrichment of ozone formed from heavily enriched oxygen isotopes, the comparison of that enrichment to ...

This study was designed to determine the relative perfor...
Thermostable direct hemolysin (TDH) is considered to be a major virulence factor in Vibrio parahaemolyticus, and most cases of V. parahaemolyticus diarrhea in humans are caused by tdh gene-positive strains. In the present study, we developed an immunochromatographic assay to detect TDH (TDH-ICA) and evaluated the utility of TDH-ICA for the diagnosis of V. parahaemolyticus diarrhea. TDH-ICA allo...
Air quality in greater Algiers, in Algeria was assessed analyzing aerosol particulate matter (PM10 and PM2.5) at a site influenced by heavy road traffic. Particulate matters were collected using a Gent sampler to characterize the atmospheric aerosol of Algiers. An Energy dispersive X ray spectrometer (EDXRF) was used to determine the heavy metal concentrations in the PM2.5 and PM10 size fractio...
