These results are interpreted as evidence that concentration quenching in Ir(ppy)(3) originates from both short and long-range energy transfer between excited and ground states of molecules. The EL quenching magnitude was found to be independent of the injection current, indicating that biexcitonic

annihilation plays a minor role. (C) 2010 American Institute of Physics. [doi: 10.1063/1.3504599]“
“Introduction. check details Ewings sarcoma (ES) is a rare tumor, most commonly encountered within the long bones during the first 20 years of life.

Case report. We report the sixth case of ES of the zygoma, occurring in a 31-year-old male, and presenting a unique reconstructive opportunity. Diagnosis and preoperative planning were aided by CT/MR coregistration. Surgical RG7112 reconstruction using 3D reconstructed CT images to produce an anatomically correct model provided the basis for a gold prosthesis construction.

Discussion. Delayed definitive reconstruction provided opportunity

for adequate tumor recurrence surveillance, and definitive histological diagnosis. The artefact produced on MR imaging from gold implants is minimal, permitting the unrestricted identification of potential future recurrence.

Conclusion. This case highlights the benefits of coregistration of radiological imaging, and custom-made gold prostheses providing the advantage of artefact-free MR imaging, which should be considered in patients requiring resection of zygomatic tumors and subsequent reconstruction.

“C5L2, a G protein-coupled receptor, is known

to be a functional receptor of acylation-stimulating protein, which is a stimulator of triglyceride synthesis and glucose transport. A novel C5L2 variant (S323I) was identified and its association with familial combined hyperlipidemia (FCH) RSL-3 was recently reported. We looked for this SNP in three Chinese ethnic groups, including Han, Uygur, and Kazakh controls and patients with FCH and type 2 diabetes. One hundred and eighty-two unrelated subjects (77 of Han, 57 of Uygur, and 48 of Kazakh) with FCH were genotyped by direct sequencing, and 852 subjects (342 of Han, 338 of Uygur, 172 of Kazakh) with type 2 diabetes and 200 healthy controls (67 of Han, 72 of Uygur, and 61 of Kazakh) chosen from a cardiovascular risk survey study were genotyped with PCR-RFLP analysis. All 182 subjects with FCH, 99.5% of the type 2 diabetes patients and 100% of the healthy controls were successfully genotyped. Neither the FCH subjects nor the type 2 diabetes patients were found to have the S323I variant. This variant was also not identified in the healthy controls. We found no evidence to demonstrate that the S323I polymorphism contributes to familial combined hyperlipidemia or type 2 diabetes in the Chinese population.
