Nitrogen fixation by a Bangladesh deepwater rice-field calothrix [PDF]

open access: yes, 1990
In order to study the influence on blue-green algal nitrogenase activity of environmental variables in deepwater rice-fields (DWR), a laboratory study was planned on a DWR isolate of Calothrix (D764).

Experiments on nitrogen fixation by nodulated lucerne [PDF]

open access: yes, 1971
Field experiments at five sites (two on clay loam, two on a sandy soil and one on chalky loam) compared dry-matter yields and nitrogen contents of lucerne and ryegrass.

Recent advances in photocatalytic nitrogen fixation and beyond. [PDF]

open access: yes, 2022
The traditional synthesis of ammonia is an industrial process with high energy consumption that is not environmentally friendly; thus, it is urgent to develop cost-effective approaches to synthesize ammonia under ambient conditions.

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.

Harnessing flavonoids to control probiotic function: in situ application of a naringenin-responsive genetic circuit

open access: yesMicrobiology Spectrum
Efforts to improve probiotics’ capabilities through synthetic biology have recently increased. Using naturally occurring plant-based compounds, such as flavonoids, as inputs of genetic circuits introduced in probiotics is a promising strategy to enhance ...

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

open access: yesAging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Nitrogen Fixation and Translocation in Sugarcane [PDF]

open access: yes, 2008
World sugarcane production is increasing rapidly as a biofuel. In some areas in Brazil, sugarcane has been grown continually over very long periods without N fertiliser inputs. Therefore, the occurrence of N fixation has been suspected.

Plasma‐water‐based nitrogen fixation: Status, mechanisms, and opportunities [PDF]

open access: yes, 2022
Nitrogen-based crop fertilizers are the most important industrial chemicals supporting the global food supply. Plasma-water-based nitrogen fixation (PWBNF) provides a clean, sustainable, and flexible alternative, which is amenable for decentralized ...
