Use of styryl 11 and STaR 11 for the luminescence enhancement of cyanoacrylate-developed fingermarks in the visible and near-infrared regions

In current casework, most post-cyanoacrylate stains rely on luminescence emission in the visible region (400-700 nm). While traditional stains such as rhodamine 6G work well under most circumstances, some surfaces may generate background luminescence under the same conditions. Detection in the near-infrared region (NIR > 700 nm) has shown to be effective in minimizing the interferences from such surfaces. The laser dye styryl 11 generated strongly luminescent fingermarks when applied after cyanoacrylate fuming on all surfaces tested. When compared to rhodamine 6G, the dye was superior only when viewed in the NIR. Styryl 11 was subsequently combined with rhodamine 6G, and the mixed stain formulation (named StaR 11 by the authors) induced stronger luminescence compared with styryl 11 alone with an ability to visualize in both the visible and NIR regions. Reliable and consistent results were obtained when using either styryl 11 alone or the STaR 11 mixture. The enhancement achieved did not otherwise vary depending on the source of the fingermark secretions. With visualization possible in both the visible and NIR regions, the styryl 11/rhodamine 6G mixture showed significant potential as a post-cyanoacrylate stain.     

Trading when you cannot trade: Blackout periods in Italian firms

This paper is part of the general debate concerning corporate governance. It focuses on a mechanism of self-regulation geared at avoiding market abuses: the use of blackout periods during which insiders are temporarily prohibited from trading on the market. Data concerning corporate characteristics, blackout periods, and internal dealing, seem to indicate that companies with a large number of independent directors and a consistent ability to monitor are more likely to adopt blackout periods. However, the research shows that during 2003 insiders did not comply with Italy's Code of Best Practice; they did not totally refrain from trading during the assigned blackout periods. All three variables measuring frequency trading – the numbers of transactions carried out, of active insiders, and of shares traded – were statistically significant during the specified blackout periods. Therefore, this paper could have practical implications for policy makers. If they decide to adopt self-regulation to fight market abuses, they must be aware that a law is only as effective as its enforcement.

XPG基因表达用于法医学年龄推断

目的探讨着色性干皮病G组(xeroderma pigmentosum group G,XPG)基因在不同年龄段健康汉族人群中的表达情况,分析XPG mRNA和蛋白表达量与年龄之间的相关性,以期为法医学年龄推断提供新的分子生物学指标。方法收集150名不同年龄段健康汉族人的外周血样,采用TRIzol法提取外周血单个核细胞(peripheral blood mononuclear cell,PBMC)总RNA,通过实时荧光定量PCR检测XPG mRNA在PBMC的相对表达量,酶联免疫吸附试验检测XPG蛋白在血浆中的表达量。结果 XPG mRNA及其蛋白表达量在≤18岁组与19~45岁组之间、≤18岁组与≥46岁组之间的差异均有统计学意义(P0.05),但19~45岁组与≥46岁组之间的差异无统计学意义(P0.05)。XPG mRNA和蛋白表达量均无性别差异(P0.05)。结论 XPG mRNA在PBMC的相对表达量在低龄段内随年龄增加而下降,其血浆中蛋白随年龄增加而升高;XPG基因有望成为法医学年龄推断的新型指标之一。     

Challenging the Ongoing Injustice of Imprisonment for Public Protection: James,Wells and Lee v The United Kingdom

The Government has recently abolished Imprisonment for Public Protection, a highly controversial form of indeterminate sentence. Yet, at the time of writing, nearly 6,000 inmates are still serving such sentences, all of whom will have to convince a Parole Board that detention is no longer necessary for the protection of the public. This paper evaluates recent European Court of Human Rights jurisprudence which considered the legality of post‐tariff detention in the absence of suitable rehabilitative provision. The Court held that there would be a violation of Article 5(1) if prisoners were held without access to such provision. Consideration is given to the implications of this ruling for those serving such sentences and, more broadly, to the impact it may have on risk‐based sentencing policies.     

青壮年猝死综合征与SCN5A基因突变的相关性

近几年来,国内外青壮年不明原因猝死的报道逐年增多,对其死因的界定是法医工作者深感棘手的问题。随着病因学向分子水平的深入,心脏病研究已用分子遗传学技术证实了一类“原发性心电紊乱”导致的心律失常与SCN5A突变引发的钠通道疾病有关,本文回顾了法医学中青壮年猝死综合征(SMDS)的特征及临床医学中几种疾病的基因型和表型,分析其相关性,期望为进一步研究获得一些启示。
