MetabolomicsSponge exhalent seawater contains a unique chemical profile of dissolved organic matter
Sponges are efficient filter feeders, removing significant portions of particulate and dissolved organic matter (POM, DOM) from the water column. While the assimilation and respiration of POM and DOM by sponges and their abundant microbial symbiont communities have received much attention, there is ...

MetabolomicsViral infection of algal blooms leaves a unique metabolic footprint on the dissolved organic matter in the ocean

Algal blooms are hotspots of primary production in the ocean, forming the basis of the marine food web and fueling the dissolved organic matter (DOM) pool. Marine viruses are key players in controlling algal bloom demise, thereby diverting algal biomass from higher trophic levels to the DOM pool,...

MetabolomicsOrganic sulfur: a spatially variable, labile, and understudied component of marine organic matter

Sulfur (S) is a major heteroatom in organic matter. This project evaluated spatial variability in the concentration and molecular-level composition of organic sulfur along gradients of depth and latitude. We measured the concentration of total organic sulfur (TOS) directly from whole seawater. Ou...

MetabolomicsA shotgun metabolomics approach to characterize the dissolved organic matter pool in the Samail Ophiolite aquifer
The process of serpentinization has been implicated in supporting life on both early Earth and other worlds in our Solar System. While numerous studies have provided clues to the survival strategies of microbial communities in serpentinizing environments on modern Earth, characterizing microbial act...

MetabolomicsDissolved organic matter produced by Thalassiosira pseudonana
Phytoplankton are significant producers of dissolved organic matter (DOM) in marine ecosystems but the identity and dynamics of this DOM remain poorly constrained. Knowledge on the identity and dynamics of DOM are crucial for understanding the molecular-level reactions at the base of the global carb...

MetabolomicsUntargeted metabolomics analysis of dissolved organic matter in the western Atlantic Ocean

The data are dissolved organic compounds from three stations sampled in the western Atlantic Ocean in 2013. Seawater samples spanning from the surface ocean to the seafloor were collected, filtered, acidified, and extracted using solid phase extraction with Bond Elut PPL cartridges. The extracts ...

MetabolomicsSponges With Microbial Symbionts Transform Dissolved Organic Matter and Take Up Organohalides (2019 collection assay)

Seawater dissolved organic matter (DOM) is a large reservoir of carbon composed of a complex and poorly characterized mixture of molecules. Sponges have long been known to consume dissolved organic carbon (DOC) from this mixture, but the role of microbial sponge symbionts in this process is compl...

MetabolomicsSponges With Microbial Symbionts Transform Dissolved Organic Matter and Take Up Organohalides (2018 collection assay)

Seawater dissolved organic matter (DOM) is a large reservoir of carbon composed of a complex and poorly characterized mixture of molecules. Sponges have long been known to consume dissolved organic carbon (DOC) from this mixture, but the role of microbial sponge symbionts in this process is compl...

MetabolomicsUsing network analysis to discern compositional patterns in ultrahigh resolution mass spectrometry data of dissolved organic matter

RATIONALE: Marine dissolved organic matter (DOM) has long been recognized as a large and dynamic component of the global carbon cycle. Yet, DOM is chemically varied and complex and these attributes present challenges to researchers interested in addressing questions about the rol...

TranscriptomicsGene expression changes in the periventricular white matter of neonatal piglets at a defined 48h time point following a hypoxic-ischemic insult: a comparison of piglets left untreated and those treated with a remote post-conditioning stimulus applied to the hind leg immediately after the insult.
Remote ischemic postconditioning (RIPostC) is a promising therapeutic intervention whereby brief episodes of ischemia/reperfusion of one organ (limb) mitigate damage in another organ (brain) that has experienced severe hypoxia-ischemia. 16 Large White newborn female piglets were exposed to a tightl...
