Abstract
Radon is considered to be the main source of human exposure to natural radiation. As stated by the World Health Organization, the exposure due to the inhalation of indoor radon is much greater than the one via the ingestion of water as radon degasses from water during handling. In response to these concerns about the universal presence of radon, environmental assessment studies are regularly commissioned to assess the radon exposure of public and workers. The credibility of such studies relies on the quality and reliability of radon analysis as well as on the sample representativeness of the radiological situation. The standard-setting approach, based on consensus, seemed to lend itself to a settlement of technical aspects of potential comparison. At present, two Working Groups of the International Standardization Organization are focussing on drafting standards on radon and its decay products measurement in air and water. These standards, which aim for a set of rigorous metrology practices, will be useful for persons in charge of the initial characterisation of a site with respect to natural radioactivity as well as to those performing the routine surveillance of specific sites.

Abstract
This study reports on ethnic differences in bone mass before and after adjusting for differences in body size and bone area (BA). Lumbar spine (LSBMC), proximal femur (PFBMC) and femoral neck (FNBMC) bone mineral contents were measured in black ('black'; n = 263) and white ('white'; n = 73) children from Johannesburg and children of mixed ancestral origin ('mixed'; n = 64) from Cape Town, South Africa. Geometric estimates and the power coefficient from the regression analyses of BMC on BA were calculated. After adjusting for age, weight, and height, LSBMC in girls and FNBMC in girls and boys were greatest in mixed, followed by black and then white, groups. Mixed boys and girls also had greater PFBMC than their black and white peers, but only in the boys was PFBMC greater in the black than the white groups. When including BA in the adjustment, differences remained at the FN in boys and girls, and the LS and PF in girls, but disappeared at the PF in mixed and black boys. The difference in LSBMC between mixed and black boys became significant after adjustment for age, weight, height, and BA. Geometric estimates at the femoral neck were greater in the mixed group. Power coefficients were greater in the white group, suggesting differences in shape or bone distribution. In conclusion, this study suggests that, in addition to differences in BMC, differences in bone strength and geometry are present which might confer advantages to the bone of mixed-ancestry children.

Abstract
BACKGROUND Plaque composition rather than degree of luminal narrowing may be predictive of acute coronary syndromes (ACS). The purpose of the study was to compare plaque composition and distribution with multi-slice computed tomography (MSCT) between patients presenting with either stable coronary artery disease (CAD) or ACS. METHODS MSCT was performed in 22 and 24 patients presenting with ACS or stable CAD, respectively. Coronary lesions were classified as calcified, non-calcified or mixed while signal intensity (SI) was measured. RESULTS In patients with stable CAD, the majority of lesions were calcified (89%). In patients with ACS, less calcifications were observed with a greater proportion of non-calcified (18%) or mixed (36%) lesions (P<0.001). Accordingly, mean SI of plaques was significantly less in ACS (320+/-201 HU versus 620+/-256 HU in stable CAD, P<0.001). Dividing lesions in the ACS group according to culprit versus non-culprit vessel location resulted in no significant difference in average SI between these two groups while still lower as compared to stable CAD (P<0.001). CONCLUSIONS In patients with ACS, significantly less calcifications were present as compared to stable CAD. Moreover, even in non-culprit vessels, multiple non-calcified plaques were detected, indicating diffuse rather than focal atherosclerosis in ACS.

Abstract
11027 Background: Some recent publications indicated that the use of G-CSF could be connected to an increase in CTC as well as elevated levels of tumor markers such as CA 27.29. In the SUCCESS Trial CTC and CA27.29 are examined before and after adjuvant chemotherapy (CHT) in 3754 breast cancer patients (pts). Methods: The SUCCESS Trial is a phase III trial comparing FEC-Docetaxel vs. FEC-Doc-Gemcitabine regime and 2 vs. 5 years of treatment with zoledronate in patients with primary breast cancer (BC) (N+ or high risk). Blood samples are taken before and after CHT. CTC were assessed with the CellSearchSystem (Veridex, Warren, USA). After immunomagnetic enrichment with an anti-Epcam-antibody, cells were labeled with anti-cytokeratin (8,18,19) and anti-CD45 antibodies to distinguish epithelial cells and leukocytes. CA27.29 has been measured with ST AIA-PACK Ca27.29 reagent using MUC-1 for AIA-600II (Tosoh Bioscience, Tessenderlo, Belgium). The cutoff for CA27.29 is 32 U/ml and >1 cell for the CTC analysis. Patients were grouped to CTC/CA27.29 raise or no raise and 1 to 6 cycles with G-CSF or no G-CSF at all. Results: Data on 1510 pts are available for CTC analysis. 745 pts (49%) received at least one course of G-CSF. 117 pts (8%) showed an increase in CTC after CHT. In this group 52 (3%) pts received G-CSF and 65 (4%) did not. 693 pts with stable or decreased CTC received G-CSF (46%) and 700 did not (46%). There was no significant difference (p=0.29). The analysis of CA27.29 is based on the data of 2556 pts. 1252 pts (49%) received at least one course of G-CSF. 338 pts (13%) exceeded the threshold for CA27.29 only after CHT. In this group 209 pts (8%) received G-CSF and 129 (5%) did not. 1043 pts with stable or decreased CA27.29 received G-CSF (41%) and 1175 did not (46%). This difference was highly significant (p<0.0001). Conclusions: No evidence can be provided for a significant correlation between an increase in the number of CTC and the application of G-CSF over CHT. Nevertheless the results on CA27.29 showed a highly significant correlation between the administration of G-CSF and elevated CA27.29 levels directly after CHT. This could be a possible explanation for the often observed increase of tumor markers after CHT. [Table: see text]

Abstract
The gamma decay from Coulomb excitation of 68Ni at 600 MeV/nucleon on a Au target was measured using the RISING setup at the fragment separator of GSI. The 68Ni beam was produced by a fragmentation reaction of 86Kr at 900 MeV/nucleon on a 9Be target and selected by the fragment separator. The gamma rays produced at the Au target were measured with HPGe detectors at forward angles and with BaF2 scintillators at backward angles. The measured spectra show a peak centered at approximately 11 MeV, whose intensity can be explained in terms of an enhanced strength of the dipole response function (pygmy resonance). Such pygmy structure has been predicted in this unstable neutron-rich nucleus by theory.

Abstract #2067
Background: Changes in biochemical markers of bone turnover are expected to be predictors of long-term changes in bone mineral density (BMD). We studied the potential of bone-specific alkaline phosphatase (BSAP) and serum N-telopeptide (sNTX) at 6 and 12 months (mo) in predicting BMD of the lumber spine (LS) and total hip (TH) at 48 mo in Z-FAST study.
 Methods: Postmenopausal women with ER+ and/or PR+ early stage breast cancer were randomized 1:1 into Up-front (U) or Delayed (D) arms (N=301 in each). Patients (pts) in U received zoledronic acid (ZOL) 4 mg IV q6 mo starting at baseline; pts in D started ZOL q6 mo when their LS or TH T-score fell below -2. All pts started Letrozole 2.5 mg/day for 5 years. Levels of BSAP and sNTX were assessed at screening and every 6 mo on a subset of pts. LS and TH BMD were assessed by dual-energy x-ray absorptiometry (DEXA) at screening, 6 mo and every 12 mo thereafter for all available pts. This is an exploratory analysis to investigate the correlation between short-term % changes from baseline in BSAP and sNTX and long-term % changes from baseline in BMD. Pearson correlations and Receiver Operating Characteristics (ROC) analysis were performed. We report the results based on 48 mo data.
 Results: The Pearson correlations between % change in BSAP at 6 mo and LS BMD at 48 mo were -0.13 [(N=38, not significant (NS)] and -0.17 (N=39, NS) in arms U and D respectively. The correlations between % change in BSAP at 12 mo and LS BMD at 48 mo were -0.15 (N=39, NS) in U and -0.43 (N=38, p=0.0077) in D. Very similar correlations were obtained for % change in sNTX at 6, 12 mo and LS BMD at 48 mo in D, but in U the correlations were smaller and positive. The correlations between % change of both markers at 6, 12 mo and TH BMD at 48 mo were all NS at 0.05. ROC analysis showed that at best performance (maximum of sensitivity plus specificity), for any increase in sNTX at 12 mo, the sensitivity (SE), specificity (SP), positive predictive value (PPV) and negative predictive value (NPV) to predict LS BMD loss at 48 mo was 74%, 77%, 85% and 63% in D. For BSAP change of 3%, the four ROC parameters were 71%, 71%, 81% and 59% respectively. For prediction of TH BMD loss, the SE, SP and NPV were lower for both markers with higher PPV. In U, the SE, SP and PPV were all much lower with very high NPV for both markers and BMD loss.
 Conclusion: Interim results of Z-FAST data show that short-term changes in BSAP and sNTX have the potential for predicting long-term bone loss. The weaker correlations in U also suggest that zoledronic acid may have a direct preventive effect on bone loss independent of changes in the markers.
