Health Promoter is one of the health professionals in all institutions. Different educational backgrounds, levels, competencies and functional positions can affect performance field. This study aims to analyze competence its effect on promoters. type research an exploratory survey with a quantitative approach. The population promoters Central Java. sample was 114 people selected by simple rando...

The promoter selectivity of Escherichia coli RNA polymerase is determined by the sigma subunit with promoter recognition activity. The model prokaryote Escherichia coli contains seven species of the sigma subunit, each recognizing a specific set of promoters. The major sigma subunit, sigma-70 encoded by rpoD, plays a major role in transcription of growth-related genes. Concomitant with the incr...

Group VIII B metal oxides supported on gamma-alumina were investigated as catalysts and promoters of MoO3 hydrodesulfurization catalysis. Superior promotion was observed in PbO promoted catalyst compared to that of CoO, the typically accepted promoter. Other metal oxides, SnO and Ho2O3 exhibited reasonable hydrodesulfurization catalysis promotion but lower than for CoO promoted catalyst.

Several hundred Arabidopsis genes, transcriptionally regulated by phytochrome A (phyA), were previously identified using an oligonucleotide microarray. We have now identified, in silico, conserved sequence motifs in the promoters of these genes by comparing the promoter sequences to those of all the genes present on the microarray from which they were sampled. This was done using a Perl script ...

Actinomycetes are important organisms for the biosynthesis of valuable natural products. However, only a limited number of well-characterized native constitutive promoters from actinomycetes are available for the construction and engineering of large biochemical pathways. Here, we report the discovery and characterization of 32 candidate promoters identified from Streptomyces albus J1074 by RNA...

Trypanosoma brucei evades the mammalian immune response by a process of antigenic variation. This involves mutually exclusive and alternating expression of telomere-proximal variant surface glycoprotein genes (vsgs), which is controlled at the level of transcription. To examine transcription repression in T.brucei we inserted reporter genes, under the control of either rRNA or vsg expression si...

BACKGROUND Transcription factors CREB, C/EBPβ and Jun regulate genes involved in keratinocyte proliferation and differentiation. We questioned if specific combinations of CREB, C/EBPβ and c-Jun bound to promoters correlate with RNA polymerase II binding, mRNA transcript levels and methylation of promoters in proliferating and differentiating keratinocytes. RESULTS Induction of mRNA and RNA po...

Background: ATP-binding cassette membrane transporter G2 (ABCG2) gene is one of transporter family and well characterized for their association with chemoresistance. Promoter methylation is a mechanism for regulation of gene expression. O6-Methyl guanine DNA methyl transferase (MGMT) gene plays a fundamental role in DNA repair. MGMT has the ability to remove alkyl adducts from DNA at the O6 pos...

The effect of using natural growth promoters (NGP) to replace traditional antimicrobials on performance, biometry digestive and reproductive organs, sexual maturity bone characteristics replacement pullets was evaluated; the relationship between these variables according diets verified. Eight-week-old birds were randomly assigned a completely randomized design fed different diets: negative cont...
