NR activity

The study described the preparation of composite material through the dispersion of carbon nanotubes (CNTs) decorated with silver nanoparticles (Ag NPs) in the matrix of blending natural rubber (NR) and polyethylene (PE) for use as an antibacterial agent. The FESEM results indicated the uniform and defect-free surface of the synthesized composites.

Apart from being the most urbanized and largest emitter of CO2 emissions in Africa, South Africa currently harbours an ecological deficit territory mainly due to its desire to attain more growth with less attention to its natural environment. Since environmental distortions are mainly an outcome of human activities, this study becomes the first to investigate the linkage between natural resource (NR), human capital, energy consumption, and ecological footprint (EF) in South Africa.

The study indicated that the PPFM and PGRs could be effectively improving drought tolerance capacity of tomato crop under drought. Among the PGRs and different concentrations of PPFM used, PPFM (2%) was found to superior in improving RWC, photosynthetic rate, SPAD value and proline content. The anti oxidant enzyme, catalase activity was enhanced by PPFM (2%) and salicylic acid (100 ppm) treatments which has the ability to protect the plant under abiotic stress by nullifying oxidative damage.

Effects of different sodium nitrate and iron concentrations on the production of some metabolites and pigments and the activities of some nitrate assimilation enzymes [nitrate reductase (NR), nitrite reductase (NiR), glutamine synthetase and glutamate synthase (GOGAT)] were investigated in the growth medium of Spirulina platensis (Gamont) Geitler.

This study investigated the correlation between endogenous levels of some signal compounds [nitric oxide (NO), salicylic acid (SA), abscisic acid (ABA)] and the antioxidant system in response to chilling stress in maize (Zea mays L.). The results showed that chilling stress caused oxidative damage, and changes in signal molecules (NO, SA, and ABA) and NR activity in maize.

Nuclear receptors (NRs) are ligand-regulated, DNA-binding transcription factors that function in the chromatin environment of the nucleus to alter the expression of subsets of hormone-responsive genes. It is clear that chromatin, rather than being a passive player, has a profound effect on both transcriptional repression and activation mediated by NRs.
