A sensitive method for detecting bromate in bread by ion chromatography with inductivelycoupled plasma mass spectrometry (IC/ICP-MS) was developed. Bromate was extracted from bread with water. The clean-up procedure included a 0.2 mm filter, a C 18 cartridge for defatting, a silver cartridge to remove halogen anions, a centrifugal ultrafiltration unit to remove proteins, and a cation-exchange cartridge to remove silver ions. A 500 mL sample solution was applied to IC/ ICP-MS. The detection

Recovery of bromate was about 90῍, and the CV was about 2῍. Based on the detection limit in solution and recovery from bread, the detection limit of bromate in bread was estimated to be 2 ng/g.

2014 Radiological Physics and Technology  
Our purpose in this study was to evaluate the variation of calculated doses caused by respiration in stereotactic body radiotherapy (SBRT) of the lung. The study targeted 10 patients who underwent SBRT for lung tumors. CT images were acquired during free breathing, and in the inhalation and exhalation phases. We compared the CT image at inhalation with the image at exhalation so as to measure the change in lung volume, variation of the CT value, and displacement of the chest wall. The lung

A statistically significant difference was observed in the CT values between inhalation and exhalation (p<0.05). The total dose variation at the isocenter was confined within ±2%. However, the dose from individual beams can vary significantly when the chest wall moves more than 10 mm in natural breathing.

Runninghead: Involvement of prostaglandin E2 in interstitial cystitis Key words: bladder pain syndrome, interstitial cystitis, prostaglandin E2 2 2 ABSTRACT (250 words) Purpose: To examine the precise role of prostaglandin E2 (PGE2) and E-series prostaglandin (EP) receptor in the pathophysiology of interstitial cystitis/bladder pain syndrome (IC/BPS). Materials and Methods: Twenty female patients with IC/BPS (11 ulcer-type and 9 non ulcer-type), 9 female controls with other urological diseases

O'Leary-Sant Score (OSS) for symptoms and problems and voluntary urine for PGE2 analysis were obtained from all objectives. Under anesthesia, the bladder was distended by saline in a stepwise fashion (from 100 ml to maximum capacity) in patients with IC/BPS, and the infused saline was retrieved each time for PGE2 analysis. We also measured PGE2 and expression of EP receptors mRNA in bladder biopsy tissue in patients with IC/BPS. Results : Symptoms and problems index in patients with ulcer-type was significantly higher than those with non ulcer-type. Urinary PGE2 in patients with ulcer-type was significantly higher than those with non ulcer-type and normal volunteers. PGE2 level in retrieved saline in patients with ulcer-type increased depending on infusion volume, but not in those with non ulcer-type. PGE2 content in bladder biopsy tissue was significantly higher in patients with ulcer-type than controls. In patients with ulcer-type, expression of EP1 and EP2 mRNA was significantly higher than controls. Conclusions: Overproduction of PGE2 in the bladder seems to play a pathophysiological role in patients with ulcer-type IC/BPS via EP1 and EP2 receptors. Localized blockade of the action of PGE2 may lead to relieving symptoms in patients with ulcer-type IC/BPS.

2014 Design, Automation & Test in Europe Conference & Exhibition (DATE), 2014  
In this paper, we demonstrate that we can reduce the communication latency significantly by inserting a fraction of randomness into a wireless 3D NoC (where CMOS wireless links are used for vertical inter-chip communication) when considering the physical constraints of the 3D design space. Towards this end, we consider two cases, namely 1) replacing existing horizontal 2D links in a wireless 3D NoC with randomized shortcut NoC links and 2) enabling full connectivity by adding a randomized NoC
more » ... yer to a wireless 3D platform with partial or no horizontal connectivity. Consequently, the packet routing is optimized by exploiting both the existing and the newly added random NoC. At the same time, by adding randomly wired shortcut NoCs to a wireless 3D platform, a good balance can be established between the modularity of the design and the minimum randomness needed to achieve low latency, and experimental results show that by adding a random NoC chip to wireless 3D CMPs without built-in horizontal connectivity, the communication latency can be reduced by as much as 26.2% when compared to adding a 2D mesh NoC. Also, the application execution time and average flit transfer energy can be improved accordingly.

2009 BMC Bioinformatics  
During this recent decade, microarray-based single nucleotide polymorphism (SNP) data are becoming more widely used as markers for linkage analysis in the identification of loci for disease-associated genes. Although microarray-based SNP analyses have markedly reduced genotyping time and cost compared with microsatellite-based analyses, applying these enormous data to linkage analysis programs is a time-consuming step, thus, necessitating a high-throughput platform. Results: We have developed
more » ... P HiTLink (SNP High Throughput Linkage analysis system). In this system, SNP chip data of the Affymetrix Mapping 100 k/500 k array set and Genome-Wide Human SNP array 5.0/6.0 can be directly imported and passed to parametric or model-free linkage analysis programs; MLINK, Superlink, Merlin and Allegro. Various marker-selecting functions are implemented to avoid the effect of typing-error data, markers in linkage equilibrium or to select informative data. Conclusion: The results using the 100 k SNP dataset were comparable or even superior to those obtained from analyses using microsatellite markers in terms of LOD scores obtained. General personal computers are sufficient to execute the process, as runtime for whole-genome analysis was less than a few hours. This system can be widely applied to linkage analysis using microarraybased SNP data and with which one can expect high-throughput and reliable linkage analysis.
