Distribution profile of 2,5-dimethoxy-4-bromoamphetamine (DOB) in rats after oral and subcutaneous doses

2,5-Dimethoxy-4-bromoamphetamine (DOB) is one of the potent hallucinogenic phenylalkylamines, whose ingestion has already caused several deaths reported all over the world. However, there is unsufficient information on DOB properties based on controlled pharmacokinetic studies available. The aim of this study was to clarify the distribution profile of DOB and its phenolic metabolite 2-methoxy-5-hydroxy-4-bromoamphetamine (2M5H4BA) in blood and biological tissues of experimental rats. The rats were administered a 20 mg/kg dose of DOB·HCl by oral ingestion or subcutaneous injection. Plasma and brain, liver and lung tissues were collected at 0.5, 1, 2, 4, 8, 16, and 32 h after dosing (three animals per time point). The samples were prepared by a liquid–liquid extraction procedure and the extracts were assayed by GC–MS. After per oral application, DOB peak plasma level of 320 ng/mL was reached after one-hour post dosing as well as 2M5H4BA peak concentration of 203 ng/mL. A rapid phase of DOB absorption, 2M5H4BA formation and their tissue distribution during the first two hours after application were followed by a slow decrease rate of the elimination process until 32 h. After subcutaneous application, high plasma levels of the unchanged parent drug and relatively reduced formation of its metabolite 2M5H4BA were observed. DOB maximum plasma concentration of 1143 ng/mL was reached after one-hour post application, whereas its metabolite peak level after 8 h was 213 ng/mL. The concentration profiles of both compounds in plasma after per oral and subcutaneous administration revealed the existence of significant first pass effect after per oral administration that significantly affected DOB bioavailability. DOB tissue concentrations exceeded plasma and the highest values were found in the lungs, where drug accumulation occurred with prolonged retention till 32 h after subcutaneous dose. Although the plasma/tissue transfer was more effective for the lipophilic parent drug than for its hydroxylated metabolite 2M5H4BA, the metabolite tissue levels were significant. The hallucinogenic potential of 2M5H4BA appearing in brain remains unclear as nothing is known about its pharmacological activity at present.     

Detection of deception with fMRI: Are we there yet?

A decade of spectacular progress in functional magnetic resonance imaging (fMRI) technology and systems neuroscience research has so far yielded few changes in our daily lives. The dearth of clinical applications of this prolific and academically promising research tool began raising the eyebrows of the public and the research funding agencies. This may be one of the reasons for the enthusiasm and interest paid to the growing body of literature suggesting that blood oxygenation level‐dependent (BOLD) fMRI of the brain could be sensitive to the differences between lie and truth. The word ‘differences’ is critical here since it refers to the often‐ignored core concept of BOLD fMRI: it is only sensitive to differences between two brain states. Thus, available studies report using fMRI to discriminate between lie and truth or some other comparative state rather than to positively identify deception. This nuance is an example of the extent to which applied neuroscience research does not lend itself to the type of over‐simplification that has plagued the interpretation of fMRI‐based lie detection by the popular press and the increasingly vocal academic critics. As an early contributor to the modest stream of data on fMRI‐based lie detection, I was asked by Dr Aldert Vrij to write a piece in favour of fMRI‐based lie detection, to be contrasted with a piece by Dr Sean Spence presenting an opposite point of view ( Spence, 2008 ). This seemingly straightforward task presented two hurdles: having to respond to the popular as well as scientific view of what lie detection with fMRI is and present a wholly positive view of evolving experimental data.     

Representation beyond people: Lobbying access of umbrella associations to legislatures and the media

Lobbying access to policy discussions determines how political interests are voiced and potentially exert influence. This article addresses whether access to the national legislature and the media favors umbrella organizations, which represent interests of their member groups. It theorizes that the role of umbrellas goes beyond signaling a large individual membership or constituency of people, but that umbrellas are distinct in transmitting interests from other organizations. This function is expected to be valuable in exchanges with legislators who seek efficiency, input legitimacy, and policy implementation, but less valuable in the media arena. Using a new data set on lobbying by 286 groups on 12 issues in the United Kingdom and Germany, the article serves support for this theory: Umbrellas enjoy higher legislative access, but lower media access than groups without member organizations, irrespective of their individual membership or claimed constituency. The findings have implications for how we understand and study political representation.     

Communicating in the post‐truth era: Analyses of crisis response strategies of Presidents Donald Trump and Rodrigo Duterte

The rhetoric of then U.S. President‐elect Donald Trump and Philippines' President Rodrigo Duterte had triggered a shift in global political discourse (Greene, 2016 ). This study examines their responses on three similar crises: disrespectful remarks towards women, associations with controversial political figures, and remarks threatening geopolitical relations. Data from prestige publications, Washington Post (U.S.) and the Philippine Daily Inquirer, were analyzed during the acute stage of each crisis. Findings showed that both men employed confusing strategy combinations in their crisis responses. Despite incoherent application and contradictory strategies, they survived threats to their image as evidenced by poll results. New strategies (diversion and logorrhea) and a strategy amplifier (machismo) were uncovered. These strategies tapped on ambiguity and were found to be successfully employed in a post‐truth landscape. This study builds on Benoit's ( 2006 ) argument that “any attempt by a president to repair a damaged image … clearly merits scholarly attention” (p. 138).     

Industry/University Licensing: Characteristics, Concerns and Issues from the Perspective of the Buyer

The authors previously explored invention licensing from the university's perspective. In this paper we focus on the process from the perspective of firms activity engaged in licensing technology. A survey of industry licensing professionals addresses why some firms license technologies from universities and why others do not. The paper then considers the stage of development of university technologies, the characteristics of their licensing contracts, and sources of information about university technologies, all to better understand how the process works and what advantages and disadvantages it offers to all participants.     

Residential Aged Care Policy in Australia – Are We Learning from Evidence?

The residential aged care industry in Australia will expand rapidly over the next 10 years leading to substantial increases in government expenditure. Recent and future reforms are likely leading to changes in the structure of the industry with a potential impact on quality of care. The purpose of this paper is to stimulate broader public debate, based on the available evidence, about the preferred structure of this important industry. It examines the literature on the impact structure has on the quality of services and compares this with a fresh analysis of current trends. The paper argues that future policy should be evidence based and explicit about the structure of the industry that will emerge from current policy reforms.     

The correctional staff burnout literature

Correctional staff job burnout is costly to all involved. As such, it has generated a growing body of research. This study reviewed 53 empirical studies of correctional staff burnout and two review articles published between 1981 and 2014. The majority of studies focused on staff working in a variety of institutional positions, fewer studies focused exclusively on the subgroup of correctional officers, and even fewer focused on a different subgroup. The majority of studies also involved staff at US government-run adult prisons. Most but not all studies utilized Maslach’s Burnout Inventory. Research on the antecedents of job burnout among correctional staff is more common than research on the possible consequences or outcomes of job burnout. Interestingly, despite the empirical emphasis on antecedents of burnout, there has been almost no research on effective interventions designed to deal with correctional staff burnout. Based on this narrative review, significant gaps remain in the research on correctional staff burnout.
