OBJECTIVES/HYPOTHESIS Currently, drug-induced sleep endoscopy (DISE) in obstructive sleep apnea (OSA) is predominantly performed in supine position. When positional therapy (avoidance of supine sleeping position in positional OSA (POSA) is implemented as (part of the) treatment, one should assess levels of obstruction in the other sleeping positions. Therefore, the current study examined the in...

Numerical studies of hole migration along short DNA hairpins were performed with a particular emphasis on the variations of the rate and quantum yield of the charge separation process with the location of a single guanine:cytosine (G:C) base pair. Our calculations show that the hole arrival rate increases as the position of the guanine:cytosine base pair shifts from the beginning to the end of ...

The recognition of human tRNA(Leu) or tRNA(Ser) by cognate aminoacyl- tRNA synthetases has distinct requirements. Only one base change (A73-->G) in tRNA(Leu) is required to generate an efficient serine acceptor in vitro, whereas several changes in three structural domains (the acceptor stem, DHU loop and long extra arm) of tRNA(Ser) are necessary in order to produce a leucine acceptor. Hence, t...

statement of problem: assessment of mandibular size and position is essential when planning a treatment strategy for patients with class ii malocclusion. purpose: this study was carried out to evaluate the mandibular size and position of 8-13 year-old children with class ii division 1 malocclusion whom were referred to the faculty of dentistry, shiraz university of medical sciences, iran. mater...

Isomerization of a closed to open complex of a promoter upon RNA polymerase binding involves base unpairing at the -10 region. After potassium permanganate sensitivity of unpaired thymine residues, we studied base unpairing at the -10 region during isomerization upon RNA polymerase binding at the P1 and P3 promoters of the gal operon. Substitution of adenine by 2-amino purine (2-AP) at the inva...

In this paper new method for vibration control of Flexible Base Mobile Manipulator (FBMM) under constrained motion control were proposed. When robotic manipulator with base flexibility contacts environment under impedance control, vibration occurs at transient and contact moments. Vibration causes position and force inaccuracy, instability and servicing requirements of equipment. Previous activ...

introduction: the aim of this study was to evaluate the effect of bridge orientation in casting machine on castability and quality of base metal castings. methods: three groups of patterns with different direction and lengths in casting machine were casted and then studied qualitatively and quantitatively using mean and standard deviation in table of frequency. results: larger nodules and poros...

The objective of this study was to determine the sagittal spinal curvatures and pelvic position in standing and kneeling in the canoe in young canoeists. Forty-four young highly-trained canoeists (mean age: 15.11 ± 0.61 years) were recruited. Thoracic and lumbar curvatures and pelvic inclination were evaluated with a Spinal Mouse system in standing position and in the base position (kneeling on...
