Surgery-first approach vs traditional approach.

We have reconstituted human mitochondrial transcription in vitro on DNA oligonucleotide templates representing the light strand and heavy strand-1 promoters using protein components (RNA polymerase and transcription factors A and B2) isolated from Escherichia coli. We show that 1 eq of each transcription factor and polymerase relative to the promoter is required to assemble a functional initiation complex. The light strand promoter is at least 2-fold more efficient than the heavy strand-1 promoter, but this difference cannot be explained solely by the differences in the interaction of the transcription machinery with the different promoters. In both cases, the rate-limiting step for production of the first phosphodiester bond is open complex formation. Open complex formation requires both transcription factors; however, steps immediately thereafter only require transcription factor B2. The concentration of nucleotide required for production of the first dinucleotide product is substantially higher than that required for subsequent cycles of nucleotide addition. In vitro, promoter-specific differences in post-initiation control of transcription exist, as well as a second rate-limiting step that controls conversion of the transcription initiation complex into a transcription elongation complex. Rate-limiting steps of the biochemical pathways are often those that are targeted for regulation. Like the more complex multisubunit transcription systems, multiple steps may exist for control of transcription in human mitochondria. The tools and mechanistic framework presented here will facilitate not only the discovery of mechanisms regulating human mitochondrial transcription but also interrogation of the structure, function, and mechanism of the complexes that are regulated during human mitochondrial transcription.

The aim of this study was to investigate whether an association exists between orthodontic treatment need and oral health-related quality of life (OHRQoL) and whether this association is moderated by self-esteem (SE) and/or personality traits. In this cross-sectional study comprising 189 adults (55 males and 134 females) aged 17 or older (mean age 31.3 years), the OHRQoL was scored by the use of the shortened version of the Oral Health Impact Profile-14 (OHIP-14). The Rosenberg self-esteem scale was used to evaluate SE, and the Dutch adaptation of the Neuroticism Extraversion Openness Five-Factor Inventory was used to assess personality profiles. Need for treatment was defined by the Index of Orthodontic Treatment Need. Spearman correlations, Mann-Whitney U-tests, and regression models were used to analyse the data. There is a modest to weak association between treatment need (Dental Health Component and aesthetic component) and OHRQoL as measured by the total OHIP-14 score (ρ = 0.21, P = 0.01216; ρ = 0.18, P = 0.02960, respectively). A significant, yet modest to weak, association between SE and the total OHIP-14 score was found (ρ = -0.34, P = 0.00057). Moreover, significant associations were found for the total OHIP-14 score and neuroticism and extraversion. Significant associations can be found between SE and all personality traits. There was a significant association between orthodontic treatment need and OHRQoL. Moreover, a significant association can be found between SE and OHRQoL, as well as certain personality traits and OHRQoL. No evidence was found that SE or personality traits moderate the association between OHRQoL and treatment need.
