Novel synthetic opioids contribute considerably to the opioid epidemic, especially with the frequent emergence of structurally similar compounds. This case report describes a fatal intoxication involving 2-methyl AP-237. A 54-year-old Caucasian male was found deceased from an apparent drug overdose. A plastic container labeled “2MAP” and a cut straw were found in the decedent's backpack at the scene. A white substance found in the container tested positive for fentanyl by field testing. According to his medical history, the decedent was treated for a drug overdose 3 years prior to his death. With no diagnostic findings at autopsy, the case was submitted for toxicological analysis. An unknown substance was detected in peripheral blood and urine using gas chromatography with nitrogen phosphorous detection (GC-NPD). Further testing was conducted using gas chromatography–mass spectrometry (GC–MS) and liquid chromatography-quadrupole-time-of-flight mass spectrometry (LC-QTOF-MS) which confirmed the presence of 2-methyl AP-237 and potential metabolites in blood and urine. Quantitation by GC-NPD revealed concentrations of 2-methyl AP-237 in blood and urine at 480 ng/mL and 4200 ng/mL, respectively. The toxicological analysis also identified and quantitated alprazolam in the blood at 55 ng/mL. Additionally, the metabolism of 2-methyl AP-237 was investigated and three hydroxylated metabolites were identified in peripheral blood and urine. Limited literature is available for the detection and quantitation of 2-methyl AP-237 in postmortem specimens. Given the toxicological findings with unremarkable autopsy findings, this case is an example of a fatal intoxication involving 2-methyl AP-237. 相似文献

While canines are most commonly trained to detect traditional explosives, such as nitroaromatics and smokeless powders, homemade explosives (HMEs), such as fuel–oxidizer mixtures, are arguably a greater threat. As such, it is imperative that canines are sufficiently trained in the detection of such HMEs. The training aid delivery device (TADD) is a primary containment device that has been used to house HMEs and HME components for canine detection training purposes. This research assesses the odor release from HME components, ammonium nitrate (AN), urea nitrate (UN), and potassium chlorate (PC), housed in TADDs. Canine odor recognition tests (ORTs) were used with analytical data to determine the detectability of TADDs containing AN, UN, or PC. Headspace analysis by gas chromatography/mass spectrometry (GC/MS) with solid-phase microextraction (SPME) or online cryotrapping were used to measure ammonia or chlorine, as well as other unwanted odorants, emanating from bulk AN, UN, and PC in TADDs over 28 weeks. The analytical data showed variation in the amount of ammonia and chlorine over time, with ammonia from AN and UN decreasing slowly over time and the abundance of chlorine from PC TADDs dependent on the frequency of exposure to ambient air. Even with these variations in odor abundance, canines previously trained to detect bulk explosive HME components were able to detect all three targets in glass and plastic TADDs for at least 18 months after loading. Detection proficiency ranged from 64% to 100% and was not found to be dependent on either age of material. 相似文献

This work presents a data survey regarding the qualitative chemical analysis of drugs seized by the Police in the state of Minas Gerais between July 2017 and June 2022, including an evaluation of labeling of 265 samples of anabolic androgenic steroids (AAS) seized in 2020. The Active Pharmaceutical Ingredients (API) present in the samples were identified through chemical analysis and classified by system Anatomical Therapeutic Chemical (ATC) methods. Analysis of the labeling information for 265 samples of AAS followed the guidance of legislation RDC 71 (2009) from ANVISA. For this study 6355 seized pharmaceuticals underwent qualitative chemical analysis that corresponded to 7739 APIs successfully identified and classified. Among the components studied AAS, psychostimulants, anesthetics, and analgesics were the most commonly examined. AAS seized and tested increased by over 100% and for the majority of the samples analyzed were found to not match the labeling on the packaging. In the meantime, anti-obesity drugs presented a prominent increase of 400% from 2020/1 to 2021/2, during covid-19 quarantine. Seized pharmaceuticals and tests can support information in the planning of public health and safety policies. 相似文献

This article argues that Vladimir Putin's regime launched support programs for the leading Russian universities in 2005 because of a perceived threat of the political mobilization of youth, similar to the one that triggered “color revolutions” in Serbia, Georgia, and Ukraine. The support programs created cleavages in the university community, covered an attack on university autonomy, and made the containment of possible anti-regime student mobilization a part of an implicit agreement between the regime and the universities. The historical coincidence of the “demographic hole,” which caused a shrinkage of the higher education market, and high oil prices, which provided the necessary resources for the regime, made this implicit agreement possible. The article contributes to the research on authoritarianism, youth mobilization, authoritarian backlash after the color revolutions, and the development of research universities in Russia. 相似文献

ABSTRACTThe Peruvian parliament was a central institution in the early republic, but so far very little has been written on its history. This is due to the fact that military leaders took control of power for most of the nineteenth century. This article reflects on three main questions: what was the role of the legislative in nineteenth-century Peru? What was its relationship with the executive power? And what part did conflict play in these relationships? Most initial congresses were tasked with writing up constitutions, because institutions had to be created, and there was a strong belief that having a written charter mattered. The strongmen who took power felt the need to obtain legitimacy from both constitutions, and elections, but often did not see eye to eye with congress. This led congress to be closed, particularly when legislators refused to bow down to presidential power. 相似文献

This study examines neuropsychological impairment in women who have experienced intimate partner violence using DSM 5 criteria for mild and severe cognitive impairment. A total of 108 females in Spain were included in one of three groups: psychological abuse (n = 24), physical and psychological abuse (n = 45), and no-abuse (n = 39). There were differences between the control and IPV groups in attention and executive functioning. Furthermore, approximately 25% of women experiencing IPV suffer mild neuropsychological alterations and 5% severe, mostly in memory and executive function domains. This evidence supports the growth in research that suggests psychological violence on its own to be as strongly related to poor health outcomes as physical violence in intimate partner relationships. 相似文献

Abstract The paper analyses the developing relations of the European Union and North Atlantic Treaty Organisation, both adapting to a new international security environment and building a network of interactions with each other. While the nature and functions of these two organisations remain different, their aims are becoming closer and new capabilities are being formed to achieve the same goals. The paper looks first at the declared level of cooperation with its benefits and limits, questioning whether this level corresponds to the practical one. It then envisages the modalities of EU–NATO practical cooperation in Bosnia and in the Western province of Sudan, Darfur. 相似文献
