Mechanistic insight on a chimeric Cas9 protein's specificity for DNA target with 5 '-NAA-3' PAM
… Cas protein with consistent specificity for a 5'-NAA-3' PAM by rationally combining the PAM-interacting domain of Streptococcus macacae with the S. pyogenes Cas9 scaffold. We have been able to demonstrate during in vitro incubations that our chimeric protein is capable of cleaving dsDNA with an …

Altered Ovarian Cancer Metabolism Increases Neuronal N-Acetylaspartate to Promote Tumor Growth
… altered metabolism compared to the normal ovary. NAA is one of the most up-regulated metabolites in HGSOC. High levels of NAA are associated with worse overall survival in HGSOC. Furthermore, high expression of its biosynthetic gene (NAT8L) is associated with vii worse overall survival in HGSOC, …

Neutron activation analysis of plantinum converter and furnace mattes using a D-T sealed tube neutron generator
Neutron activation analysis (NAA) has been applied to furnace matte and converter matte samples with the objective of studying the natural variation in the elemental composition of the samples, with a view to characterize the samples for their source of origin. The experimental work was carried out …

Aerobic Exercise and Hippocampal Plasticity in Young Adults with Depression
… hippocampus volume and N-acetyl-aspartate (NAA) concentration, a marker of neuron density/viability, has been shown. The relationship of these variables to fitness (as assessed by volume of oxygen uptake - VO2 max) is underexplored. In this study, unmedicated, inactive young adults with MDD …

In vitro separation of chimeral pears into their component genotypes
… of Thiadizuron (TDZ) and Naphthaleneacetic acid (NAA) on shoot regeneration was investigated. Among the different levels of TDZ used, a range of 3 to 7 uM was optimum for most cultivars, while a level of 4.5 to 5 uM NAA gave the best regeneration for the two cultivars, 'Seckel' and 'Louise Bonne …
