Chromophoric dissolved organic matter (CDOM) fluorescence or absorption is often proposed as a rapid alternative to chemical methods for the estimation of bulk dissolved organic carbon (DOC) concentration in natural waters. However, the robustness of this method across a wide range of systems remains to be shown. We measured CDOM fluorescence and DOC concentration in four tropical freshwater an...

The quantitative role of the Atlantic Meridional Overturning Circulation (AMOC) in dissolved organic carbon (DOC) export is evaluated by combining DOC measurements with observed water mass transports. In the eastern subpolar North Atlantic, both upper and lower limbs of the AMOC transport high-DOC waters. Deep water formation that connects the two limbs of the AMOC results in a high downward ex...

20 Determining the concentration and composition of dissolved organic carbon (DOC) in glacial 21 ecosystems is important for assessments of in situ microbial activity and contributions to 22 wider biogeochemical cycles. Nonetheless, there is limited knowledge of the abundance and 23 character of DOC in basal ice and the subglacial environment and a lack of quantitative data 24 on low molecular ...

Bile acids increase the proliferative activity of rat colonie epithelium. However, the mechanisms responsible are unknown. The present study examined the relationships between deoxycholate (DOC) induced surface cell sloughing, as measured by loss of DNA into the lumen and by light microscopy, and the subsequent increases in mucosal ornithine decarboxylase activity and | 'I l|tli> mulino (dl lid...

Photosynthates released by benthic primary producers (BPP), such as reef algae and scleractinian corals, fuel the dissolved organic carbon (DOC) production on tropical coral reefs. DOC concentrations near BPP have repeatedly been observed to be elevated compared to those in the surrounding water column. As the DOC release of BPP increases with increasing light availability, elevated DOC concent...

Studies suggest that pre-administration of docetaxel (DOC) in adriamycin (ADR)-DOC combination anticancer therapy results in stronger antitumor effects and fewer ADR-induced cardiotoxic deaths in mouse model, yet no mechanism explaining this effect has been established. The aim of this study was to identify cellular processes in mouse heart tissue affected by different ADR/DOC dosing protocols ...
