Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

open access: yesFEBS 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 ...

Re-os isotope constraints on the age of the Lithospheric mantle beneath western Greenland. [PDF]

open access: yes, 2007
Alkaline magmatic activity across Western Greenland (W.G.) provides a record of lithosphere evolution over the last 600 Ma. Ultra Mafic Lamprophyre (UML) magmatism in particular has erupted an exceptional inventory of mantle xenoliths allowing a detailed

Re-Os isotopic investigation of the Stillwater Complex, Montana

open access: yesEarth and Planetary Science Letters, 1989
Abstract Samples from the J-M Reef and the G-chromitite horizons of the Stillwater Complex were analyzed for their Re and Os concentrations and Os isotopic compositions. There is large variability in the 187 Os/ 186 Os ratio both within the G-chromitite and between the horizons, that is unsupported by in-situ Re decay since the time at which the ...

Cyclic azapeptide CD36 ligand attenuates cardiac injury and reduces long‐chain fatty acid accumulation after myocardial ischemia–reperfusion in mice

open access: yesFEBS Open Bio, EarlyView.
In a murine model of myocardial ischemia and reperfusion (MI/R), the CD36 azapeptide ligand MPE‐298 reduces cardiac injury and transiently lowers left ventricular long‐chain fatty acids (LCFAs) accumulation 3 h after reperfusion, accompanied by a decrease of oxidative stress and inflammation‐associated genes' expression in the heart and adipose tissue.

Nickel and osmium isotope and trace element geochemistry of organic-rich sedimentary rocks: The first investigation of Ni isotope systematics in marine sediments [PDF]

open access: yes, 2012
Understanding the chemical composition of organic-rich marine sediments has the potential to: 1) allow evaluation of variations in ocean chemistry, enabling assessment of changes in global processes throughout geological time; and 2) provide an increased

Re-Os isotope system in organic-rich samples for dating and tracing: Methodology, principle, and application

open access: yes, 2023
In the last three decades, significant progress has been made in the investigation of rhenium-osmium (Re-Os) isotopic system in organic-rich samples. The Re-Os geochronometer can provide precise absolute depositional ages of organic-rich sediments (ORS ...

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

open access: yesFEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

Origin and Geochronology of Chang'anpu Mo-Cu Deposit in Jilin Province: Constraints from Molybdenite Re-Os Isotope Systematics

open access: yesYankuang ceshi, 2016
The east-central part of Jilin Province, located on the continental margin of northeast China along the eastern Xing-Meng orogenic belt, hosts more than 10 large-and medium-scale Mo deposits. The major types of mineralization include porphyry, skarn, and
