Degradation and Preservation of Organic Matter in Marine Sediments
Organic matter that is deposited in aquatic sediments is subject to an intense diagenetic reactor that determines how much organic carbon is...

Biological Markers for Anoxia in the Photic Zone of the Water Column
In this chapter we review the current state of knowledge on the occurrence of anoxic conditions in the water column of past depositional systems...

Controls on the Carbon Isotopic Compositions of Lipids in Marine Environments
Organic carbon isotopes have long been used to study modern and ancient biogeochemical processes. Controls on the isotopic composition of organic...
-
Sources and Cycling of Organic Matter in the Marine Water Column
The organic carbon cycle operates on multiple time scales with a only small fraction of the global reservoir actively exchanged. For the marine...

Atmospheric Transport of Terrestrial Organic Matter to the Sea
The transport of atmospheric particles with associated terrestrial organic matter to the oceans is an important process affecting various global...
-
Sources and Fate of Organic Contaminants in the Marine Environment
The sources, levels, and fate of organic contaminants of major concern in the marine environment are reviewed. Spatial distributions among the...

Identification of volatile metabolites produced from levodopa metabolism by different bacteria strains of the gut microbiome
Interspecies pathways in the gut microbiome have been shown to metabolize levodopa, the primary treatment for Parkinson’s disease, and reduce its...

C4-like Sesuvium sesuvioides (Aizoaceae) exhibits CAM in cotyledons and putative C4-like + CAM metabolism in adult leaves as revealed by transcriptome analysis
BackgroundThe co-occurrence of C 4 and CAM photosynthesis in a single species seems to be unusual and rare. This is likely due to the difficulty in...

Age-related dysregulation of CXCL9/10 in monocytes is linked to impaired innate immune responses in a mouse model of Staphylococcus aureus osteomyelitis
BackgroundAge-associated impairments in innate immunity are believed to be a causative factor responsible for severe pathogenesis of Staphylococcus...
