Validation of the Direct Analysis in Real Time Source for Use in Forensic Drug Screening

Abstract:  The Direct Analysis in Real Time (DART) ion source is a relatively new mass spectrometry technique that is seeing widespread use in chemical analyses world-wide. DART studies include such diverse topics as analysis of flavors and fragrances, melamine in contaminated dog food, differentiation of writing inks, characterization of solid counterfeit drugs, and as a detector for planar chromatography. Validation of this new technique for the rapid screening of forensic evidence for drugs of abuse, utilizing the DART source coupled to an accurate mass time-of-flight mass spectrometer, was conducted. The study consisted of the determination of the lower limit of detection for the method, determination of selectivity and a comparison of this technique to established analytical protocols. Examples of DART spectra are included. The results of this study have allowed the Virginia Department of Forensic Science to incorporate this new technique into their analysis scheme for the screening of solid dosage forms of drugs of abuse.     

Persistence of innovation: stylised facts and panel data evidence

This paper investigates whether firms innovate persistently or discontinuously over time using an innovation panel data set on German manufacturing and service firms for the period 1994–2002. It turns out that innovation behaviour is permanent at the firm level to a very large extent. Using a dynamic random effects discrete choice model and a new estimator recently proposed by Wooldridge (2005), I further shed some light on the driving forces for this phenomenon. The econometric results show that past innovation experience is an important determinant for manufacturing as well as for service sector firms, and hence confirm the hypothesis of true state dependence. In addition, the results highlight the important role of knowledge provided by skilled employees and unobserved individual heterogeneity in explaining the persistence of innovation.

MAGNA CARTA AND THE FUNDAMENTAL RIGHT TO DUE PROCESS

The 800th anniversary of Magna Carta has been marked by much pageantry and celebration. Some scholars have taken this opportunity to point out that the myth of Magna Carta is far greater than what the actual 1215 Charter managed to accomplish. Nevertheless, Magna Carta did make a meaningful and concrete contribution to due process in 1215, as shown by certain provisions that are seemingly overlooked by critics eager to downplay the Charter’s importance. This article highlights two lesser known clauses of Magna Carta that had real contemporary significance in guaranteeing the availability of jury trial for some categories of civil litigation. The ringing promises of Clauses 39 and 40 may have inspired great jurists and founders of nations, but the more humble Clauses 17 and 18 — specifying the proper location and manner of hearing certain civil cases — must also be taken into account in assessing the Charter’s importance.     

Evaluation of GLOCK 9 mm Firing Pin Aperture Shear Mark Individuality Based On 1,632 Different Pistols by Traditional Pattern Matching and IBIS Pattern Recognition

Over a period of 21 years, a number of fired GLOCK cartridge cases have been evaluated. A total of 1632 GLOCK firearms were used to generate a sample of the same size. Our research hypothesis was that no cartridge cases fired from different 9‐mm semiautomatic GLOCK pistols would be mistaken as coming from the same gun. Using optical comparison microscopy, two separate experiments were carried out to test this hypothesis. A subsample of 617 test‐fired cases were subjected to algorithmic comparison by the Integrated Ballistics Identification System (IBIS). The second experiment subjected the full set of 1632 cases to manual comparisons using traditional pattern matching. None of the cartridge cases were “matched” by either of these two experiments. Using these empirical findings, an established Bayesian probability model was used to estimate the chance that a 9‐mm cartridge case, fired from a GLOCK, could be mistaken as coming from the same firearm when in fact it did not (i.e., the random match probability).     

揿针治疗癌症相关性失眠的系统评价与Meta分析

目的 系统评价揿针治疗癌症相关性失眠（cancer-related insomnia,CRI）的疗效和安全性。方法 从中国知网、万方数据库、重庆维普中文科技期刊数据库、中国生物医学文献数据库、PubMed、Embase和Cochrane Library电子数据库中检索自建库至2023年12月揿针治疗CRI的随机对照试验文献,由2名评价者根据纳入和排除标准纳入文献并进行数据提取,采用RevMan 5.3.0软件进行数据的整合分析。结果 检索到符合纳入标准的文献6篇,共计500例患者。Meta分析结果显示,与对照组比较,揿针治疗可显著降低匹兹堡睡眠质量指数（Pittsburgh sleep quality index,PSQI）总分［MD=－2.31,95% CI（－2.84,－1.78）,P＜0.000 01］。同时治疗组的入睡时间、睡眠质量、睡眠时间、睡眠障碍、睡眠效率和日间功能均优于对照组;揿针治疗CRI在提高总有效率方面有优势［RR=0.38,95% CI（0.26,0.57）,P＜0.000 01］,且在每日1~3次的中频次刺激下,可通过延长疗程来提高疗效［12 d：MD=－2.17,95% CI（－3.75,－0.59）;28 d：MD=－2.41,95% CI（－3.15,－1.66）］;在达到或超过15 d的较长疗程治疗下,每日1~3次的中频次刺激比低于每日1次的低频次刺激疗效显著［中频次：MD=－2.41,95% CI（－3.15,－1.66）;低频次：MD=－1.50,95% CI（－3.38,0.38）］。安全性方面,有2篇文献报道轻微不良反应,1篇文献报道不良反应不明,其余均未报道不良反应。结论 揿针治疗可显著改善CRI患者睡眠,在提高睡眠质量方面具有优势,安全性较高。

针灸治疗糖尿病胃轻瘫随机对照试验文献质量评价

［摘要］目的 对针灸治疗糖尿病胃轻瘫随机对照试验文献质量进行分析，为进一步的临床试验研究提供参考。方法 检索近30年针灸治疗糖尿病胃轻瘫临床研究文献，采用循证医学的原则及评价方法，制定临床文献评价及信息采集表，对纳入文献进行分析和评价。结果 检索到符合纳入标准的临床对照试验文献21篇，在样本量估算、疾病诊断标准及疗效判定标准、盲法和分配隐藏、随机化实施、随访及病例脱失剔除情况、结局指标选择、安全性观察、结论推导等方面存在一些问题。结论 针灸治疗糖尿病胃轻瘫的临床研究文献存在样本量较少、研究方法实施不严谨、结局指标选取不统一的缺点，尚不能得出针灸优于其他疗法的确切结论，故有必要进一步做多中心、大样本及高质量的临床试验研究。

中药治疗糖尿病足溃疡结局评价的问题与对策

药物的疗效和安全性通过结局指标的报告来体现,因此恰当地选择并报告结局指标是临床研究中应该重视的关键环节.目前中药治疗糖尿病足随机对照试验的文献在结局指标的选择和报告方面存在以下问题:滥用综合性指标评价结局;结局评价指标模糊不清;结局评价指标不分主次;结局评价标准不统一;缺少对不良事件的报告.因此,应明确定义主次结局指标...
