摘要： 数字对象唯一标识符（digitalobjectidentifier，DOI）是对包括互联网信息在内的数字信息进行标识的一种工具。在传统的出版物中，书刊、磁带、光盘都有国际标准编号（ISBN、ISSN、ISCN）及其条形码，作为出版物的唯一标识。这些标识使出版物得到有效的管理，便于读者查找和利用。而网上的文档一旦变更了网址便无从追索。数字信息所标注的DOI如同出版物的条形码，是一个永久和唯一的标识号。随着时间推移，数字对象的某些有关信息可能会有变化（包括存储的物理位置），

摘要： Background. Adhesive capsulitis is often difficult to diagnose in its early stage and to differentiate from other common shoulder disorders. Objective. The aim of this study was to validate any or all of the 8 clinical identifiers of early-stage primary/idiopathic adhesive capsulitis established in an earlier Delphi study. Design. This was a cross-sectional study. Methods. Sixty-four patients diagnosed with early-stage adhesive capsulitis by a physical therapist or medical practitioner were included in the study. Eight active and 8 passive shoulder movements and visual analog scale pain scores for each movement were recorded prior to and immediately following an intra-articular injection of corticosteroid and local anesthetic. Using the local anesthetic as the reference standard, pain relief of >= 70% for passive external rotation was deemed a positive anesthetic response (PAR). Results. Sixteen participants (25%) demonstrated a PAR. Univariate logistic regression identified that of the proposed identifiers, global loss of passive range of movement (odds ratio [OR]=0.26, P=.03), pain at the end of range of all measured active movements (OR=0.06, P=.02), and global loss of passive glenohumeral movements (OR=0.23, P=.02) were associated with a PAR. Following stepwise removal of the variables, pain at the end of range of all measured active movements remained the only identifier but was associated with reduced odds of a PAR. Limitations. The lack of a recognized reference standard for diagnosing early-stage adhesive capsulitis remains problematic in all related research. Conclusions. None of the clinical identifiers for early-stage adhesive capsulitis previously proposed by expert consensus have been validated in this study. Clinicians should be aware that commonly used clinical identifiers may not be applicable to this stage.

摘要： Pharmaceutical analysis comprises a large amount of the casework in forensic controlled substances laboratories. In order to reduce the time of analysis for pharmaceuticals, a Direct Analysis in Real Time ion source coupled with an accurate mass time-of-flight (DART-TOF) mass spectrometer was used to confirm identity. DART-TOF spectral data for pharmaceutical samples were analyzed and evaluated by comparison to standard spectra. Identical mass pharmaceuticals were differentiated using collision induced dissociation fragmentation, present/absent ions, and abundance comparison box plots;principal component analysis (PCA) and linear discriminant analysis (LDA) were used for differentiation of identical mass mixed drug spectra. Mass assignment reproducibility and robustness tests were performed on the DART-TOF spectra. Impacts on the forensic science community include a decrease in analysis time over the traditional gas chromatograph/mass spectrometry (GC/MS) confirmations, better laboratory efficiency, and simpler sample preparation. Using physical identifiers and the DART-TOF to confirm pharmaceutical identity will eliminate the use of GC/MS and effectively reduce analysis time while still complying with accepted analysis protocols. This will prove helpful in laboratories with large backlogs and will simplify the confirmation process. (C) 2014 Elsevier Ireland Ltd. All rights reserved.
