FEBS Open Bio, EarlyView.Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Journal of Magnetic Resonance (1969), 1985 Nowadays many possibilities exist to elucidate carbon-carbon connectivity. In hydrogen-bearing carbon systems C-C connectivities can be traced out most conveniently in an indirect way by a combination of H-H COSY (I) and H-C CQSY (2). In case of overlapping ‘proton signals ambiguities can be removed by heteronuclear relayed spectroscopy (3) and ...

Bacteriophages as a model for studying carbon regulation in aquatic system [PDF]
, 2012 The interconversion of carbon in organic, inorganic and refractory carbon is still beyond the grasp of present environmentalists. The bacteria and their phages, being the most abundant constituents of the aquatic environment, represent an ideal model for

Cellulose carbon-CVD carbon composites
Carbon, 1975 Carbon-carbon composites have been fabricated using a cellulose powder which is molded at low pressures, carbonized at 800°C and infiltrated by a CVD technique at 700°C using propylene as a source of carbon. Infiltration rate at time t is governed by the amount of open porosity existing in the sample at this time.

Simulations of stable compact proton beam acceleration from a two-ion-species ultrathin foil
, 2011 We report stable laser-driven proton beam acceleration from ultrathin foils consisting of two ion species: heavier carbon ions and lighter protons. Multi-dimensional particle-in-cell (PIC) simulations show that the radiation pressure leads to very fast ...

Cutaneous Melanoma Drives Metabolic Changes in the Aged Bone Marrow Immune Microenvironment
Aging and Cancer, EarlyView.Melanoma, the deadliest form of skin cancer, increasingly affects older adults. Our study reveals that melanoma induces changes in iron and lipid levels in the bone marrow, impacting immune cell populations and increasing susceptibility to ferroptosis.
