Bomb-14C analysis of ecosystem respiration reveals that peatland vegetation facilitates release of old carbon [PDF]
The largest terrestrial-to-atmosphere carbon flux is respired CO2. However, the partitioning of soil and plant sources, understanding of contributory mechanisms, and their response to climate change are uncertain.

Experimental substantiation of permeabilized hepatocytes model for investigation of mitochondria in situ respiration [PDF]
To verify experimentally the model of permeabilized hepatocytes, the degree of cell permeability was assessed using trypan blue and polarographycally determined cell respiration rate upon succinate (0.35 mM) and α-ketoglutarate (1 mM) oxidation ...

Role of Second Quinone Binding Site in Proton Pumping by Respiratory Complex I
Respiratory complex I performs the reduction of quinone (Q) to quinol (QH2) and pumps protons across the membrane. Structural data on complex I have provided spectacular insights into the electron and proton transfer paths, as well as into the long (~30 ...

Alternative oxidase dependent respiration leads to an increased mitochondrial content in two long-lived mutants of the aging model Podospora anserina [PDF]
The retrograde response constitutes an important signalling pathway from mitochondria to the nucleus which induces several genes to allow compensation of mitochondrial impairments.

ESTIMATING CONTRIBUTION OF ZOOXANTHELLAE TO ANIMAL RESPIRATION (CZAR) AND TO ANIMAL GROWTH (CZAG) OF GIANT CLAM Tridacna maxima [PDF]
Zooxanthellae are symbiotic dinoflagellate algae which live in association with marine invertebrates including giant clams. These algae are capable of translocating part of their photosynthetic products to the host.

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

Bacteria hold their breath upon surface contact as shown in a strain of Escherichia coli, using dispersed surfaces and flow cytometry analysis. [PDF]
Bacteria are ubiquitously distributed throughout our planet, mainly in the form of adherent communities in which cells exhibit specific traits. The mechanisms underpinning the physiological shift in surface-attached bacteria are complex, multifactorial ...

Largen: A Molecular Regulator of Mammalian Cell Size Control [PDF]
Little is known about how mammalian cells maintain cell size homeostasis. We conducted a novel genetic screen to identify cell-size-controlling genes and isolated Largen, the product of a gene (PRR16) that increased cell size upon overexpression in human

Sensors and multi-sensor arrays are the basis of new technologies for the non-label monitoring of cell activity. In this paper we show that choroid plexus cells can be cultured on silicon chips and that sensors register in real time changes in their ...
