in this study, incorporation of iron ion-doped natrolite nanozeolite, multi-wall carbon nanotubes into chitosan-coated glassy carbon electrode for the simultaneous determination of ascorbic acid, epinephrine, uric acid and tyrosine is studied. the results show that the combination of multi-wall carbon nanotubes and iron ion-doped natrolite zeolite causes a dramatic enhancement in the sensitivit...

Fusarium wilt caused by Fusarium oxysporum f.sp. Lycopersici is one of the major obstacles to the production of tomato which causes huge losses in tomato products worldwide. In order to increase the tolerance to this disease, a triple structure containing PR1, chitinase and glucanase genes controlled by 35S promoter was transferred to tomato. Eight days after planting on pre-culture me...

The Display of Negative Emotions scale and Social Consequences Of are two understudied questionnaires that assess parents’ emotion beliefs about their children’s expression negative emotions. Therefore, the aims this study were to ascertain factorial structure both questionnaires, reexamine internal consistency each instrument’s scales, age- gender-related discriminant validity measures. admini...

Here, we report a new zinc-inducible expression system for Lactococcus lactis, called Zirex, consisting of the pneumococcal repressor SczA and PczcD. PczcD tightly regulates the expression of green fluorescent protein in L. lactis. We show the applicability of Zirex together with the nisin-controlled expression system, enabling simultaneous but independent regulation of different genes.

We previously showed that the sequential, but not simultaneous, culture of endothelial cells (ECs), fibroblasts (FBs), and cardiomyocytes (CMs) resulted in elongated, beating cardiac organoids. We hypothesized that the expression of Cx43 and contractile function are mediated by vascular endothelial growth factor (VEGF) released by nonmyocytes during the preculture period. Cardiac organoids (~20...

We report for the first time the functional simultaneous expression of nine genes from a single 2A peptide based polycistronic expression construct. The feasibility and arising opportunities for the biosynthetic pathway balancing for chemical production were demonstrated by the co-expression of the violacein and carotenoid biosynthesis pathways.
