“Objective. The purpose of this study was to analyze craniofacial characteristics from lateral head profile radiographs of patients with cri-du-chat (CdC) syndrome.

Study design. The craniofacial morphology of 10 CdC

patients was evaluated using standard cephalometric methods, measuring 39 craniofacial variables on cephalometric x-ray images.

Results. The principal characteristics were skeletal class II malocclusion, caused by mandibular retrognathism, dental biprotrusion, and a small upper airway. Additionally, 70% of patients had a steep palatal plane angle; the cranial base angle was flattened, also in 70% KU-57788 mouse of patients.

Conclusions. Results indicated that the deletion of 5p had an impact on the cranial base, maxilla, mandible, and upper airway, causing distinctive features to become apparent through irregular growth. (Oral Surg Oral Med Oral Pathol Oral Radiol Endod 2010;110:e38-e44)”
“Lagerstroemia

(crape myrtle) are famous ornamental plants with large pyramidal racemes, long flower duration, and diverse colors. However, little is known about the genetic structure and diversity of germplasm in Lagerstroemia. We genotyped 81 L. indica cultivars, five other species of Lagerstroemia, and 10 interspecific hybrids using 30 simple sequence repeat markers; 275 alleles were generated with a mean of nine alleles per locus. The mean polymorphism information content value, a measure of gene diversity, was 0.63, with a range from 0.25 to 0.86. The mean observed heterozygosity (0.51) tended to be lower than the mean expected heterozygosity (0.67). The mean F-statistics (F-ST,

F-IS, and F-IT) were 0.05, 0.20, and 0.24, respectively, indicating a high level of genetic variation among cultivars. Clustering analysis based on genetic distance divided the 96 genotypes into three distinct groups, which corresponded with their SB203580 ic50 genetic backgrounds and geographic regions. L. indica cultivars and the other five L. species were grouped into different sub-clusters. Chinese and North American cultivars were divided into different clusters. These data about the genetic relationship among cultivars demonstrated the potential value of L. indica cultivars and other Lagerstroemia species for widening the genetic basis of breeding programs for this ornamental flower.”
“Hyper-Raman scattering is used to investigate the vibrations in two prototypical relaxors, PbMg(1/3)Nb(2/3)O(3) and PbMg(1/3)Ta(2/3)O(3) (PMT). First-order scattering from polar modes is clearly observed. Most of the triply-degenerate cubic vibrations are split into doublets and their frequencies compare very well to that of PbTiO(3) in its tetragonal phase. Their shape and scattering intensities are sensitive to the local chemical ordering and ferroelectric distortions.
