A full-scale process has been developed to immobilize fission products that accumulate within the Mark IV electrorefiner (ER) electrolyte at Idaho National Laboratory. ER salt was blended with treatment additives, followed by pressureless consolidation (PC) in a furnace to produce a durable ceramic waste form (CWF). The goal is the development of a process to consolidate actual radioactive ER salt into a form suitable for transportation and disposal. Four batches (300 to 400 kg per batch) of full-scale pre-qualification material preparation runs have been prepared. From these four batches of nonradioactive salt-loaded surrogate material, three full-scale PC trials have been conducted. The first PC test run, established equipment parameters with a basic CWF container design. The second trial included a modified CWF container design, real-time measurement of CWF consolidation, and an audio recording to identify cracking during the CWF cool-down. During the third trial, salt was doped (from the fourth material preparation batch) to create a nonradioactive salt material and to more closely represent actual ER salt. The second and third trials were also used to validate a model developed for the CWF. The CWF model is beneficial for understanding and predicting the physical processes that occur during the heat cycle. This would be particularly useful when the CWF is located in a hot cell, which makes accessing and examining a CWF difficult.

Design and Development of a Multimodal Biomedical Information Retrieval System

Demner-Fushman, Dina,Antani, Sameer,Simpson, Matthew,Thoma, George R. Korean Institute of Information Scientists and Eng 2012 Journal of Computing Science and Engineering Vol.6 No.2

The search for relevant and actionable information is a key to achieving clinical and research goals in biomedicine. Biomedical information exists in different forms: as text and illustrations in journal articles and other documents, in images stored in databases, and as patients' cases in electronic health records. This paper presents ways to move beyond conventional text-based searching of these resources, by combining text and visual features in search queries and document representation. A combination of techniques and tools from the fields of natural language processing, information retrieval, and content-based image retrieval allows the development of building blocks for advanced information services. Such services enable searching by textual as well as visual queries, and retrieving documents enriched by relevant images, charts, and other illustrations from the journal literature, patient records and image databases.

qEEG Measures of Attentional and Memory Network Functions in Medical Students: Novel Targets for Pharmacopuncture to Improve Cognition and Academic Performance

Objectives: Attentional and memory functions are important aspects of neural plasticity that, theoretically, should be amenable to pharmacopuncture treatments. A previous study from our laboratory suggested that quantitative electroencephalographic (qEEG) measurements of theta/beta ratio (TBR), an index of attentional control, may be indicative of academic performance in a first-semester medical school course. The present study expands our prior report by extracting and analyzing data on frontal theta and beta asymmetries. We test the hypothesis that the amount of frontal theta and beta asymmetries (fTA, fBA), are correlated with TBR and academic performance, thereby providing novel targets for pharmacopuncture treatments to improve cognitive performance. Methods: Ten healthy male volunteers were subjected to 5-10 min of qEEG measurements under eyes-closed conditions. The qEEG measurements were performed 3 days before each of first two block examinations in anatomy-physiology, separated by five weeks. Amplitudes of the theta and beta waveforms, expressed in μV, were used to compute TBR, fTA and fBA. Significance of changes in theta and beta EEG wave amplitude was assessed by ANOVA with post-hoc t-testing. Correlations between TBR, fTA, fBA and the raw examination scores were evaluated by Pearson’s product-moment coefficients and linear regression analysis. Results: fTA and fBA were found to be negatively correlated with TBR (P<0.03, P<0.05, respectively) and were positively correlated with the second examination score (P<0.03, P=0.1, respectively). Conclusion: Smaller fTA and fBA were associated with lower academic performance in the second of two first-semester medical school anatomy-physiology block examination. Future studies should determine whether these qEEG metrics are useful for monitoring changes associated with the brain’s cognitive adaptations to academic challenges, for predicting academic performance and for targeting phamacopuncture treatments to improve cognitive performance.

Matrix‐assisted laser desorption/ionization mass spectrometry reveals decreased calcylcin expression in small cell lung cancer

Lee, Hee Seok,Park, Jun Won,Chertov, Oleg,Colantonio, Simona,Simpson, John T.,Fivash, Matthew J.,Yoo, Chong Woo,Lee, Geon Kook,Zo, Jae Ill,Kim, Heung Tae,Kim, Hark Kyun Blackwell Publishing Asia 2012 Pathology international Vol.62 No.1

<P>To date, most of the proteomic analyses on lung cancer tissue samples have been performed using surgical specimens, which are obtained after a diagnosis is made. To determine if a proteomic signature obtained from bronchoscopic biopsy samples could be found to assist with diagnosis, 50 lung cancer bronchoscopic biopsy samples and 13 adjacent normal lung tissue samples were analyzed using histology‐directed, matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry (MS). Lung tissue samples were cryosectioned, and sinapinic acid was robotically deposited on areas of each tissue section enriched in epithelial cells, either tumor or normal. Mass spectra were acquired using a MALDI‐time of flight instrument. Small cell lung cancers (SCLCs) demonstrated clearly different protein profiles from normal lung tissue and from non‐small cell lung cancers (NSCLCs). Calcyclin (<I>m/z</I>= 10 094.7) was identified to be underexpressed in small cell lung cancers, as compared with non‐small cell lung cancers and normal lung tissue. An immunohistochemistry study using 152 NSCLCs and 21 SCLCs confirmed significantly reduced calcyclin stain in SCLCs. Thus, protein profiles obtained from bronchoscopic biopsy samples via MALDI MS distinguish cancerous epithelium from normal lung tissue and between NSCLCs and SCLCs.</P>
