Plant species richness regulates soil respiration through changes in productivity. [PDF]

open access: yes, 2010
Soil respiration is an important pathway of the C cycle. However, it is still poorly understood how changes in plant community diversity can affect this ecosystem process.

Continuous chemotrophic growth and respiration of Chromatiaceae species at low oxygen concentrations [PDF]

open access: yes, 1992
Endogenous and maximum respiration rates of nine purple sulfur bacterial strains were determined. Endogenous rates were below 10 nmol O2 · (mg protein · min)-1 for sulfur-free cells and 15–35 nmol O2 · (mg protein · min)-1 for cells containg ...

Controls on winter ecosystem respiration in temperate and boreal ecosystems [PDF]

open access: yes, 2011
Winter CO2 fluxes represent an important component of the annual carbon budget in northern ecosystems. Understanding winter respiration processes and their responses to climate change is also central to our ability to assess terrestrial carbon cycle and ...

Representation of dormant and active microbial dynamics for ecosystem modeling. [PDF]

open access: yesPLoS ONE, 2014
Dormancy is an essential strategy for microorganisms to cope with environmental stress. However, global ecosystem models typically ignore microbial dormancy, resulting in notable model uncertainties.

Nrf2 impacts cellular bioenergetics by controlling substrate availability for mitochondrial respiration [PDF]

open access: yes, 2013
Transcription factor Nrf2 and its repressor Keap1 regulate a network of cytoprotective genes involving more than 1% of the genome, their best known targets being drug-metabolizing and antioxidant genes.

Modulating Enzyme’s Activity and Specificity through Pre-Installed Posttranslational Modifications (PTMs) on Substrate: The Role of PTM-induced Substrate-Assisted Stimulation [PDF]

open access: yes, 2023
Understanding the underlying principles for crosstalk involving posttranslational modifications (PTMs) is of fundamental importance. In this article, we review some of previous results which indicated that pre-installed PTMs on nucleosome substrates (or ...

Mitochondrial Respiration in Insulin-Producing β-Cells: General Characteristics and Adaptive Effects of Hypoxia. [PDF]

open access: yesPLoS ONE, 2015
To provide novel insights on mitochondrial respiration in β-cells and the adaptive effects of hypoxia.Insulin-producing INS-1 832/13 cells were exposed to 18 hours of hypoxia followed by 20-22 hours re-oxygenation.

mPTP opening differently affects electron transport chain and oxidative phosphorylation at succinate and NAD-dependent substrates oxidation in permeabilized rat hepatocytes [PDF]

open access: yesThe Ukrainian Biochemical Journal, 2020
Mitochondrial Ca2+ overload may trigger the opening of mitochondrial permeability transition pore (mPTP) and its prolonged activation leads to cell death. ATP synthase is considered as a possible molecular component of the pore. The aim of this study was

Talking SMAAC: A New Tool to Measure Soil Respiration and Microbial Activity

open access: yesFrontiers in Earth Science, 2019
Soil respiration measurements are widely used to quantify carbon fluxes and ascertain soil biological properties related to soil microbial ecology and soil health, yet current methods to measure soil respiration either require expensive equipment or use ...
