OBJECTIVE To evaluate stainless steel archwire static friction in active and passive self-ligating lingual and conventional brackets with second-order angulations. METHODS Two conventional lingual brackets for canines (STb light/Ormco; PSWb/Tecnident), and two self-ligating brackets, one active (In-Ovation L/GAC) and the other passive (3D/ Forestadent), were evaluated. A stainless steel archw...

BACKGROUND While suicidal thoughts and behaviors (STB) among college students are common, the associations between STB and academic performance are not well understood. METHODS As part of the World Mental Health Surveys International College Student project, web-based self-reported STB of KU Leuven (Leuven, Belgium) incoming freshmen (N=4921; response rate=65.4%) was collected, as well as aca...

The stb locus of IncFII plasmid NR1, which mediates stable inheritance of the plasmid, is composed of an essential cis-acting DNA site located upstream from two tandem genes that encode essential stability proteins. The two tandem genes, stbA and stbB, are transcribed as an operon from promoter PAB. Using PAB-lacZ gene fusions, it was found that the stb operon is autoregulated. A low-copy-numbe...

The large virulence plasmid pMYSH6000 of Shigella flexneri contains a replicon and a plasmid maintenance stability determinant (Stb) on adjacent SalI fragments. The presence of a RepFIIA replicon on the SalI C fragment was confirmed, and the complete sequence of the adjacent SalI O fragment was determined. It shows homology to part of the transfer (tra) operon of the F plasmid. Stb stabilizes a...

The Saccharomyces cerevisiae 2-μm plasmid is a multicopy selfish genome that resides in the nucleus. The genetic organization of the plasmid is optimized for stable, high-copy propagation in host-cell populations. The plasmid's partitioning system poaches host factors, including the centromere-specific histone H3-variant Cse4 and the cohesin complex, enabling replicated plasmid copies to segreg...

The aim of this study was to evaluate the therapeutic potential of oxidative stress (OS) reduction by using pyridoindole (PI) antioxidants in adjuvant arthritis (AA). The substances tested were stobadine dipalmitate (STB) and SMe1. AA was used as animal model. The experiments included healthy animals, control arthritic animals and arthritic animals with administration of PI in the oral daily do...

The safety of stereotactic biopsy (STB) was studied in this article. CT-guided STB (Brown-Roberts-Wells; BRW) was performed 58 times for 56 patients (male: 29, female: 27) at Hyogo Cancer Center between 1988 and 2007. The age distribution ranged from 15 to 83 (mean: 55) years old. Histological diagnoses were established for 58 samples, with 35 cases of glioma, eight of metastatic brain tumor, n...

A field experiment was conducted at the Regional Wheat Research Centre (RWRC) of the Bangladesh Agricultural Research Institute, Gazipur, Bangladesh for 2 consecutive years during 2006-07 and 2007-08 with the objective to find out the optimum nutrient management practice on total dry matter production (above ground part) of each component crop of potatomungbean-t. aman rice cropping pattern. Tw...

Abstract Globally, bread wheat production is threatened by fungal diseases, including the devastating disease Septoria tritici blotch (STB). Given global importance of STB, and difficulty in identifying novel sources resistance to this disease, we screened a variety genotypes, wild, ancestral, mutagenized lines, for their STB response. This delineated panel wild relatives Watkins collection lin...
