CLIN CHEM:利用单指纹技术无创检测可卡因和海洛因使用情况

2018-06-21 MedSci MedSci原创

最近发表的研究探索了利用指纹来确认药物使用的可能性,但是还没有排除指尖环境的污染。在本研究中,研究人员探索了从单个指纹建立药物测试环境临界值的可能性。 在50名非药物使用者洗手前后收集指纹样本(n = 100)以建立单独的环境临界值和对可卡因,苯甲酰芽子碱,海洛因和6-单乙酰吗啡的测试方案。与毒品使用者握手后,通过测试无药物志愿者的指纹来测定临界值。此外,本研究还收集并分析了经证实服用过可卡

最近发表的研究探索了利用指纹来确认药物使用的可能性,但是还没有排除指尖环境的污染。在本研究中,研究人员探索了从单个指纹建立药物测试环境临界值的可能性。 在50名非药物使用者洗手前后收集指纹样本(n = 100)以建立单独的环境临界值和对可卡因,苯甲酰芽子碱,海洛因和6-单乙酰吗啡的测试方案。与毒品使用者握手后,通过测试无药物志愿者的指纹来测定临界值。此外,本研究还收集并分析了经证实服用过可卡因(n = 32)和海洛因(n = 24)的患者的指纹。 研究发现,根据所提供的指纹是在洗手前还是洗手后收集的,需要应用不同的临界值。应用这些临界值使得无药物志愿者的假阳性率为0%。应用临界值后,患者洗手后的检出率(与患者证词相比)为使用可卡因87.5%,使用海洛因100%。 本研究表明,与被调查的初次吸毒人群相比,指纹图谱显示证实服用该物质的患者可卡因,海洛因及其各自代谢产物的水平增加,并且可以建立临界值(决定水平)。截止值足够强大,足以解释二次转移后观察到的分析物的小幅增加。 原始出处: Mahado Ismail, Derek Stevenson, Noninvasive Detection

Hypertension:可卡因通过miR-30c-5p -苹果酸酶1-活性氧通路升高血压、促进动脉僵硬

滥用可卡因会增加心血管疾病发病率和死亡率;但是,其潜在的分子机制仍未完全了解。现有研究人员利用滥用可卡因的小鼠模型,对其分子机制进行深入研究。研究人员发现,重复注射可卡因可导致与主动脉中活性氧(ROS)水平升高相关的小鼠血压升高和主动脉僵硬,该现象与人类高血压患者的相似。ROS高水平与Me1(苹果酸酶1:消除ROS产生的重要分子)下调相关;而miRNA-30c-5p表达上调,通过直接与Me1的3'

指阿片样药物危机!澳大利亚禁止以非处方形式使用可卡因药物

澳大利亚成为了最新一个禁止以非处方形式使用包含阿片样止痛药的国家,这项新规定将在2018年2月1日生效,旨在降低可卡因导致的死亡人数。据统计2000年至今,澳大利亚由于可卡因致死的人数已经翻了两番。 可卡因可用于止痛、止咳,据研究报道,一些止痛药、止咳糖浆及感冒、流感药片中均含有低剂量可卡因,而在澳大利亚及英国不需要开处方就可以购买这些药物。 但是即使是低剂量的可卡因也有让人上瘾的风险,因为它

可卡因,上瘾背后的机制

你们知道世界上最易上瘾的物质有哪些吗?海洛因、可卡因、尼古丁、巴比妥酸盐、酒精是上瘾性最高的几类药物。一旦进入大脑,它们都会刺激多巴胺,通过奖赏回路促使大脑兴奋和愉快,从而使人沉迷而欲罢不能。

JACC:可卡因和大麻的使用可增加心梗患者死亡风险!

化学品滥用现象在青少年中越来越普遍,但其与心血管疾病发生的关系尚属未知。本研究的目的旨在评估年龄≤50岁出现有心梗成年人中可卡因和大麻的使用情况及其与远期预后的关系。本研究纳入分析了来自2家学术型医院2000-2016年诊断为1型心梗的患者,最终共纳入了2097名1型心梗患者(平均年龄44.0 ± 5.1岁,女性占19.3%,白种人占73%),平均随访时间是11.2年。分析结果显示,有224名患者

Alcohol:青春期饮用混合酒精和咖啡因的功能饮料可与可卡因一样影响大脑

近日,来自普渡大学的一项研究表明,饮用咖啡因含量很高的酒精饮料可引起与青少年使用可卡因相似的的大脑变化,且其后果持续到成年期,该研究结果已发表于Alcohol。 研究人员对青少年喂以咖啡因含量很高的能量饮料,以观察对小鼠大脑的影响。结果发现,与对照组小鼠相比,高咖啡因能量饮料组小鼠成年期并不会饮用更多地酒精。 但是当将高水平的咖啡因与酒精混合后喂以青少年小鼠后发现小鼠大脑的物理和神经化

Neuron:线粒体分裂和可卡因成瘾关系

已有的研究表明,在可卡因成瘾过程中,脑内能量平衡的改变是大脑中发生的一个关键适应过程。但是至今为止,可卡因对线粒体,能量的根本来源,的影响还是未知的。
