چکیده
Great smiles have harmony, symmetry, and a broadness consistent with the individual’s facial form, morphology, and balance. Smiles communicate, are expressive, and especially beautiful when full. People do not perceive narrow arch smiles to be appealing. A proportional smile fills the lip embrasures and eliminates black triangles. We see this as beauty in nature, and such symmetry is preferred by the public. Orthodontic capabilities have increased with improved 3-dimensional knowledge of dentofacial growth and refined facial orthopedic procedures. The technology of tooth movement, fixed functional appliance efficiencies, space-gaining methods, and nonextraction approaches further enhance facial esthetics and symmetry of the outcome. Optimal transverse dimension should be developed for esthetic and functional advantages. Facial, skeletal, and dental midlines should be centered, with pleasing facial and dental proportionality.1,2

Trophodynamics of polybrominated diphenyl ethers in the marine food web of Bohai Bay, North China.
Polybrominated diphenyl ethers (PBDEs) are of great environmental concern due to the exponential increase of the concentrations in the environment, especially in high trophic level organisms, and the trophodynamics of these chemicals in aquatic food webs is an important criterion for assessing their ecological risk. This study analyzed 13 PBDEs in the zooplankton, five invertebrate species, six...
متن کاملSignificance of renal vasodilation after administration of atrial natriuretic factor in the conscious dog.
The contribution of alterations in renal hemodynamics to the diuretic and natriuretic actions of atrial natriuretic factor (ANF) was studied in chronically instrumented conscious dogs. Injection of ANF-(99-119), 10 micrograms/kg, had no effect on mean arterial pressure, heart rate, renal blood flow, or calculated renal vascular resistance; However, it increased urine flow rate (86 +/- 20%) and ...

We have combined Rossi X-ray Timing Explorer observations of X2127+119, the low-mass X-ray binary in the globular cluster M15, with archival X-ray lightcurves to study the stability of the 17.1 hr orbital period. We find that the data cannot be fit by the Ilovaisky et al. (1993) ephemeris, and requires either a 7σ change to the period or a period derivative ˙ P /P ∼ 9 × 10 −7 yr −1. Given its r...
