Abstract
Drug-induced kidney injury (DIKI) is a major concern in both drug development and clinical practice. There is an unmet need for biomarkers of glomerular damage and more distal renal injury in the loop of Henle and the collecting duct (CD). A cross-laboratory program to identify and characterize urinary microRNA (miRNA) patterns reflecting tissue- or pathology-specific DIKI was conducted. The overall goal was to propose miRNA biomarker candidates for DIKI that could supplement information provided by protein kidney biomarkers in urine. Rats were treated with nephrotoxicants causing injury to distinct nephron segments: the glomerulus, proximal tubule, thick ascending limb (TAL) of the loop of Henle and CD. Meta-analysis identified miR-192-5p as a potential proximal tubule-specific urinary miRNA candidate. This result was supported by data obtained in laser capture microdissection nephron segments showing that miR-192-5p expression was enriched in the proximal tubule. Discriminative miRNAs including miR-221-3p and -222-3p were increased in urine from rats treated with TAL versus proximal tubule toxicants in accordance with their expression localization in the kidney. Urinary miR-210-3p increased up to 40-fold upon treatment with TAL toxicants and was also enriched in laser capture microdissection samples containing TAL and/or CD versus proximal tubule. miR-23a-3p was enriched in the glomerulus and was increased in urine from rats treated with doxorubicin, a glomerular toxicant, but not with toxicants affecting other nephron segments. Taken together these results suggest that urinary miRNA panels sourced from specific nephron regions may be useful to discriminate the pathology of toxicant-induced lesions in the kidney, thereby contributing to DIKI biomarker development needs for industry, clinical, and regulatory use.

Abstract
MicroRNAs (miRNAs) are small non-coding RNA that regulate the expression of messenger RNA and are implicated in almost all cellular processes. Importantly, miRNAs can be released extracellularly and are stable in these matrices where they may serve as indicators of organ or cell-specific toxicity, disease, and biological status. There has thus been great enthusiasm for developing miRNAs as biomarkers of adverse outcomes for scientific, regulatory, and clinical purposes. Despite advances in measurement capabilities for miRNAs, miRNAs are still not routinely employed as noninvasive biomarkers. This is in part due to the lack of standard approaches for sample preparation and miRNA measurement and uncertainty in their biological interpretation. Members of the microRNA Biomarkers Workgroup within the Health and Environmental Sciences Institute's (HESI) Committee on Emerging Systems Toxicology for the Assessment of Risk (eSTAR) are a consortium of private- and public-sector scientists dedicated to developing miRNAs as applied biomarkers. Here, we explore major impediments to routine acceptance and use of miRNA biomarkers and case examples of successes and deficiencies in development. Finally, we provide insight on miRNA measurement, collection, and analysis tools to provide solid footing for addressing knowledge gaps toward routine biomarker use.

Abstract
BACKGROUND AND PURPOSE Little is known about the methods used to assess the physical fitness of adolescents who are overweight. We investigated the relationship between walk/run performance and cardiorespiratory fitness in adolescents who are overweight. SUBJECTS Eight African-American adolescents (5 female, 3 male) and 10 Caucasian adolescents (5 female, 5 male) who were overweight (mean age=14.5 years, SD=2.0, range=12-17; mean body mass index [BMI]=42.9 kg/m2, SD=11.5) participated in this study. METHODS Subjects performed a 12-minute walk/run test. The distances traveled at both 9 minutes (D9) and 12 minutes (D12) were recorded, and the distance traveled between 9 and 12 minutes (D9-12) was calculated. Subjects also completed a maximal cycle ergometry test, during which peak oxygen uptake (VO2peak), anaerobic threshold (AT), peak power (Wpeak), and power at the anaerobic threshold (WAT) were determined. Body composition was determined by air displacement plethysmography. RESULTS The mean percentage of body fat was 48.6% (SD=5.3%, range=40.3%-60.4%). Percentage of body fat and BMI were each inversely related to D9, D12, and VO2peak (all P<.005). Peak oxygen uptake (r=.72, P=.0001), VO2peak/kg lean body mass (r=.60, P<.005), Wpeak (r=.88, P<.0001), and WAT (r=.72, P=.0007) were all related to D12, with greater r values than for D9. If D9-12was included in regression analyses, D9 did not account for additional variance in any of the cycle ergometry variables. DISCUSSION AND CONCLUSION These results suggest that an easily obtained measurement of physical performance (distance traveled during a 12-minute walk/run test) is related to cardiorespiratory fitness and to body composition in adolescents who are overweight. The 12-minute walk/run distance is more predictive of cycle ergometry test results than the 9-minute distance.

Abstract
Currently available dietary assessment tools have limited ability to obtain valid data within the resource constraints of large-scale studies. Many obstacles to gathering data can be overcome with computer-assisted self-interviewing (CASI). Computers can conduct personalized, in-depth interviews without interviewers; provide standardized data collection with appropriate levels of probing; automate data entry; encourage subjects to review and correct inconsistent data; and ensure that responses are complete. Interactive multimedia tools can motivate subjects and improve participation. Visual and aural cues may stimulate recall and improve data quality. CASI is appropriate for use in populations in which literacy is low and in multiple ethnic groups. A prototype CASI diet-history program was developed for use in the United States. The diet-history approach was selected to improve cognitive support and capture information on usual diet. Scripts were based on recorded interviews with dietitians and interviewers from the National Health and Nutrition Examination Survey. At the end of the interview, participants are given information on how their reported nutrient intakes compare with current recommendations for their age and sex. The prototype was tested in focus groups of mixed age, sex, ethnicity, and education, with encouraging results. The development of multimedia-based dietary assessment tools seems a logical next step in improving dietary assessment methods.

Abstract
The three-dimensional crystal structure of the mitogenic lectin from the green pea (Pisum sativum) has been determined at 6-A resolution by x-ray diffraction methods. Pea lectin was isolated by use of affinity chromatography and was crystallized from polyethylene glycol solutions. Crystals of pea lectin are orthorhombic, space group P212121, and diffract to at least 1.2-A resolution. The unit cell dimensions are a = 50.85(5), b = 61.23(5), and c = 137.3(2) A. The calculated mass of protein per asymmetric unit is 49,000 daltons, and the crystals are 44% solvent by volume. There are two pea lectin monomers per crystallographic asymmetric unit. Diffractometer data were collected from a native crystal and from a single site uranyl heavy atom derivative crystal. The position of the uranium atom, determined from three-dimensional Patterson maps, was refined by least squares techniques (R index - 0.46 for centric data). A three-dimensional electron density map was calculated by use of phases determined by isomorphous-replacement and anomalous-dispersion contributions. The boundaries of the pea lectin molecule are clearly visible in the map. The molecule appears to be a dimer, roughly peanut-shaped, formed by the close association of the two monomer units. In shape and size, it bears a striking resemblance to the concanavalin A dimer, in which monomers combine to form a dimer-wide contiguous antiparallel pleated sheet.
