Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

The Climate Control of Soil Organic Carbon Dynamics Inferred From Speleothem Radiocarbon Ages

Geophysical Research Letters, 2023
The complexity of processes affecting soil organic carbon (SOC) turnover on spatio‐temporal scales often hinders the extrapolation of results from specific sites to larger scales.

Compositional variations in algal organic matter during distinct growth phases in karst water

Frontiers in Environmental Science, 2023
Inland surface water plays an important role in global carbon cycling, which responds to transformation between dissolved inorganic carbon (DIC) and dissolved organic carbon (DOC).

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

FEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

Massive concentrations of old dissolved organic carbon from Yedoma thaw in lakes in Siberia

Communications Earth & Environment
Understanding the impacts of permafrost thawing on the carbon cycle requires a closer look at the proportion of dissolved and particulate organic carbon released upon thaw, and the magnitude of its conversion into greenhouse gases, which remain ...

Characterization of Laboratory-scale Tidal Flow Constructed Wetlands in the Removal of Organic Carbon and Nitrogen from Sewage

Journal of Water and Environment Technology, 2023
Tidal flow constructed wetlands (TFCWs) have been proposed as a new type of CW for enhanced wastewater treatment. However, the characterization of TFCWs in the removal of organic carbon and nitrogen remains unclear.

Low volume quantification of dissolved organic carbon and dissolved nitrogen [PDF]

Limnology and Oceanography: Methods, 2012
A method for the quantification of dissolved organic carbon (DOC) and total dissolved nitrogen (TDN) in aqueous samples of less than 600 µL is described. Analysis of low volumes is achieved through modification of a Shimadzu HTC TOC analyzer, which in its conventional configuration requires at least 7 mL sample. The modification allows manual injection

Hands‐on protocol for preparing water‐soluble fractions from agri‐food samples for NMR‐based metabolomics analysis

FEBS Open Bio, EarlyView.
This research protocol outlines a workflow for nuclear magnetic resonance (NMR)‐based metabolomics in the agri‐food sector. Using two case studies—strawberry leaves (solid matrix) and wine (liquid matrix)—it details the procedures for sample preparation, data acquisition, and processing.

Antibiofilm activity of a chionodracine‐derived peptide by NMR‐based metabolomics of cell‐free supernatant of Acinetobacter baumannii clinical strains

FEBS Open Bio, EarlyView.
KHS‐Cnd peptide is able to impair biofilm formation and disaggregate mature biofilms in Acinetobacter baumannii clinical isolates. Differences in extracellular metabolites reflect changes in biofilm metabolism due to KHS‐Cnd treatment. Among the differentially represented extracellular metabolites upon KHS‐Cnd treatment, the significantly altered ...

Carbon in an Arctic fjord: sea ice carbon transformations and CO2 linkages

Frontiers in Marine Science
IntroductionThe biogeochemical processes underlying carbon cycling in Arctic coastal systems are rapidly evolving due to intensified ice loss. (Aim) This study examined the distinct contributions of dissolved organic carbon (DOC) and particulate carbon ...
