Dissolved organic matter and microbial carbon of Protocalcic Chernozems of different land management
Бюллетень Почвенного института им. В.В. Докучаева, 2022 Water-extractable organic matter is the most active and mobile form of soil carbon. The other active fraction and extremely biolabile is the carbon constituent of microorganisms.

Comparison of soil carbon stocks in two cropping systems as affected by nitrogen application levels [PDF]
, 2013 This study aimed to trace possible changes in soil organic carbon (SOC) at different soil depths when treated with different levels on nitrogen fertilizer, in both conventional tillage and reduced tillage systems.

FEBS Open Bio, EarlyView.NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...

Temperature sensitivity of soil carbon decomposition [PDF]
, 2013 The world's soils contain three times as much carbon as the atmosphere. Thus, any changes in this carbon pool may affect atmospheric CO₂ levels with implications for climate change.

Evolution‐guided yeast complementation reveals functional differences in human PSPH variants
FEBS Open Bio, EarlyView.Ancient genomes can help guide which human genetic variants are tested experimentally. This study applies that idea to PSPH, a gene involved in serine biosynthesis, and uses high‐throughput yeast complementation to compare variant function. The findings reveal measurable differences among selected alleles and illustrate the value of evolution‐guided ...

New organic matter degradation proxies: Valid in lake systems? [PDF]
, 2004 We determined concentrations and diagenetic state of organic matter in two cores from Lake Zug, Switzerland. To obtain a general picture of organic matter decay in the lake, we measured bulk parameters such as total organic carbon, total nitrogen, and ...
