The purpose of this study to clarify the factors an effecting lip seal in Japanese adults with malocclusion. Sixty-three malocclusion patients aged 20 to 27 years were randomly selected and compared with fourteen normal occlusion controls aged 22 to 26 years old. The subjects were divided into a good seal group and a poor lip seal group by observing the distance between the upper and lower lip ...

The disturbances of orofacial functions lead to abnormal growth and development of the orofacial complex. The aim of the study was to determine the prevalence of incompetent lip seal and respiration disturbance, and to improve the understanding of correlation between incompetent lip seal and morphological malocclusions. In the sample of 84 children (45 girls and 39 boys, aged 8.96 +/- 0.66 year...

To assess the potential effects of persistent organic pollutants (POPs) on the expression of cytochrome P450 (CYP) 2B and 3A isozymes in Baikal seal, the 5′-flanking regions of these CYP genes were isolated, and transactivation analysis was performed by in vitro reporter gene assay system. The 3.2 kbp of CYP2B and 2.2 kbp of CYP3A gene promoter/enhancer regions were cloned and sequenced from Ba...

The rotordynamic and leaking characteristics of two types of gas damper seals, honeycomb seal and pocket damper seal, were experimentally evaluated on a rotating test rig. The effect of supply pressure, preswirl, and seal eccentricity on seal dynamic performance was investigated in the tests. The pressurized working gas flowed through the seal and exhausted to atmospheric conditions. The maximu...

This article pursues two tasks. The first is to clarify the value and productivity of Williams’s Keywords: a vocabulary culture society (first edition 1976, second expanded 1983a) for project Cultural Studies. clarification helped, I argue, by reading it alongside Vološinov’s Marxism philosophy language (published in Russian 1929, translated into English 1973). related task speculative developm...
