Microbial carbon mineralization in tropical lowland and montane forest soils of Peru [PDF]

open access: yes, 2016
Climate change is affecting the amount and complexity of plant inputs to tropical forest soils. This is likely to influence the carbon (C) balance of these ecosystems by altering decomposition processes e.g., "positive priming effects" that accelerate ...

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

Impact of Ecological Factors on Biocrust Performance in the Stability of Loess Soils in the Incheh Buron Region [PDF]

open access: yesDesert
Biocrusts are used as a protective cover to stabilize the soil in dry areas, where the soil is more affected by erosion. In this research, various characteristics of the soil under the biological and physical crust were investigated as indicators of soil

Substrate- and Calcium-Dependent Differential Regulation of Mitochondrial Oxidative Phosphorylation and Energy Production in the Heart and Kidney

open access: yesCells, 2021
Mitochondrial dehydrogenases are differentially stimulated by Ca2+. Ca2+ has also diverse regulatory effects on mitochondrial transporters and other enzymes. However, the consequences of these regulatory effects on mitochondrial oxidative phosphorylation
