\n\nResults:

The heart volume from planning CT images was significantly smaller than that from CBCT scans (p < 0.05), and the volumes based on the different series of CBCT images were similar (p > 0.05). The overlap of the heart region on the same anatomical section between the first series of CBCT scans and other scans reached 0.985 +/- 0.020 without statistically significant differences (p > 0.05). The mean margins of the heart from planning CT and CBCT scans were 10.5 +/- 2.8 mm in the left direction, 5.9 +/- 2.8 mm in the right direction, 2.2 +/- 1.6 mm in the direction of the head, 3.3 +/- 2.2 mm in the direction of the foot, 6.7 +/- 1.1 mm in the anterior direction, and 4.5 mm +/- 2.5 mm in the posterior Selleck TH-302 direction. All relative and absolute dose-volume indices obtained from CBCT images were significantly larger than those from planning CT scans (p < 0.05), with the exception of the volume in the 5Gy region.\n\nConclusion: The PRV

of heart contouring based on kV-CBCT is feasible with good reproducibility. More accurate and objective dose-volume indices may be obtained for NSCLC patients by using kV-CBCT, instead of CT, to plan SBRT.”
“We have studied the lattice location selleck kinase inhibitor of implanted nickel in silicon, for different doping types (n, n(+), and p(+)). By means of on-line emission channeling, Ni-65 was identified on three different sites of the diamond lattice: ideal substitutional sites, displaced bond-center towards substitutional sites (near-BC), and displaced tetrahedral interstitial towards anti-bonding sites (near-T). We suggest that the large majority of the observed lattice sites are not related to the isolated form of Ni but rather to its trapping into vacancy-related defects produced during the implantation. While near-BC sites are prominent after

annealing up to 300-500 degrees C, near-T sites are preferred after 500-600 degrees C anneals. Long-range diffusion starts at 600-700 degrees C. We show evidence of Ni diffusion towards the surface and its further trapping on near-T sites at the R-p/2 region, providing a clear picture of the microscopic mechanism of Ni gettering by vacancy-type defects. The high thermal stability of near-BC sites in n(+)-type Si, and its importance for the understanding Androgen Receptor Antagonist in vitro of P-diffusion gettering are also discussed.

“Objectives: The objectives of this study were to evaluate the effect of octreotide on number of hypoglycemic episodes and blood glucose concentrations (BGCs) in a case series of young children who received octreotide for treatment of sulfonylurea-induced hypoglycemia and to identify the frequency of adverse effects associated with octreotide’s use for this indication.\n\nMethods: A retrospective review of 9 years of National Poison Data System pediatric sulfonylurea overdoses treated with octreotide was conducted.
