Chronic Rhinosinusitis: Potential Role of Microbial Dysbiosis and Recommendations for Sampling Sites
Dioxins, furans and dioxin-like polychlorinated biphenyls (PCBs) were analysed in muscle tissue from yellow phased European eel (Anguilla anguilla) from 38 sites in Belgium. Dioxin concentrations in eel vary considerably between sampling locations, indicating that yellow eel is a good indicator of local pollution levels. Measured levels of dioxin-like PCBs are much higher than those of the diox...
Background: Many recent studies have examined potential risk factors of H. pylori gastritis to improve our understanding of the early events in gastric carcinogenesis. We evaluated the extent and topography of chronic gastritis in a high risk area for gastric cardia cancer and investigated the critical role of H.pylori, risk index and age in its pathogenesis. Materials and Methods: During a na...
ysis sampling in pharmacokinetics research has proven to have many benefits such as clean samples, more frequent samples, conservation of body fluid, and fewer animals per study. In addition, it provides a direct profile of pharmacokinetics within the tissue of interest instead of traditional methods which calculate the tissue concentration indirectly from serial blood samples. Microdialysis sa...
