    Abstract Body representations are known to be dynamically modulated or extended through tool use. Here, we review findings that demonstrate the importance of a user's tool experience or expertise for successful tool embodiment. Examining expert tool users, such as individuals who use tools in professional sports, people who use chopsticks at every meal, or spinal injury patients who use a wheelchair daily, offers new insights into the role of expertise in tool embodiment: Not only does tool embodiment differ between novices and experts, but experts may experience enhanced changes to their body representation when interacting with their own, personal tool. The findings reviewed herein reveal the importance of assessing tool skill in future studies of tool embodiment.

    Abstract Preexposure prophylaxis (PrEP) for human immunodeficiency virus (HIV) prevention is approved for use in adolescents, though uptake remains low. Black adolescent females experience higher rates of HIV transmission compared to adolescent females of other racial/ethnic groups. Increasing PrEP awareness and education among this population may be an effective strategy to mitigate disparities in HIV transmission among Black adolescent females. Twenty-seven Black adolescent females participated in focus groups which were coded using the constant comparative method of qualitative analysis to identify major themes: (1) PrEP is not commonly framed as an HIV prevention strategy for heterosexual Black adolescent females, (2) PrEP use among peers is perceived as mostly positive, (3) Adoption of PrEP among Black adolescent females is impeded by perceived barriers such as stigma, negative side effects, and adherence concerns. These findings may inform the development of targeted culturally tailored marketing and educational campaigns centered on Black heterosexual adolescent females to increase PrEP awareness and uptake in this population disproportionately affected by HIV.

    Abstract Objective: To test preliminary efficacy and acceptability of Invite Only VR: A Vaping Prevention Game (Invite Only VR), an electronic cigarette (e-cigarette) prevention game that uses virtual reality (VR) hardware.
    Methods: 285 adolescents (146 boys; ages 11-14; M = 12.45 years; SD = 0.57) were enrolled in this non-equivalent control groups design through their middle school. Participants who played Invite Only VR for 1.5 h were compared to treatment as usual at 4 timepoints: baseline, post gameplay, 3 and 6 months. Evidence of the efficacy of the game to influence e-cigarette use, e-cigarette knowledge, nicotine addiction knowledge, perceived addictiveness of e-cigarettes, perceived likelihood of using e-cigarettes, perceptions of harm, self-efficacy to refuse, social approval of e-cigarettes, and e-cigarette social perceptions was assessed using mixed between-within subjects ANOVAS. Intervention acceptability was indicated by measures of gameplay experience/satisfaction, VR experience, and perceived responsibility for game-based decisions.
    Results: From baseline to 6 months, Invite Only VR players improved in e-cigarette knowledge, nicotine addiction knowledge, perceived addictiveness of e-cigarettes, perceptions of harm, and social perceptions about e-cigarette use compared to the control group. No significant changes were observed for the other dependent variables, including e-cigarette use. Ratings of gameplay experience and satisfaction, VR experience, and game-based decisions were high.
    Conclusions: Invite Only VR may help players develop knowledge about e-cigarettes and nicotine addiction, as well as encourage the development of healthy harm and social perceptions regarding e-cigarette use that persist 6 months beyond gameplay. Adolescents' satisfaction with the VR gameplay indicates preliminary intervention acceptability.

    Abstract Objective: To test the preliminary impact and participant experience/satisfaction of Invite Only VR: A Vaping Prevention Game (Invite Only VR), an electronic cigarette (e-cigarette) prevention game prototype using virtual reality (VR) hardware.
    Methods: Forty-seven adolescents (38 boys; mean age = 14.23 years, SD = 0.914) were enrolled to test the preliminary impact of Invite Only VR on knowledge, perceived likelihood of using e-cigarettes, perceptions of harm, attitudes, social norms, and self-efficacy to refuse e-cigarettes using a pre/post design. Experience/satisfaction was measured following gameplay. Paired-samples t-tests and associated effect sizes were used to assess changes in the dependent variables. Descriptive statistics were used to report on gameplay experience/satisfaction.
    Results: From pre- to post-gameplay, players significantly increased in knowledge (t(34) = -5.594, p < .001, Cohen's d = 0.946) and perceptions of e-cigarette harm (t(34) = -3.370, p = .002, Cohen's d = 0.530) and decreased their perceived likelihood of using e-cigarettes in the future (t(35) = 2.140, p = .039, Cohen's d = 1.274). No significant change was found for attitudes towards e-cigarettes, social norm perceptions, nor refusal self-efficacy. Participants reported that they enjoyed playing the game (M = 3.00, SD = 0.99) and that they would tell their friends to play (M = 3.08, SD = 0.91).
    Conclusions: Invite Only VR may help players develop knowledge and correct harm perceptions regarding e-cigarettes while reducing their perceived likelihood of using them in the future. Participant enjoyment also provides an initial indication that the intervention may be acceptable for use with adolescents.

    Abstract Arthritis develops in DBA/1xB10A(4R) mice and Wistar rats upon intraplantar injection of potassium peroxochromate (K3CrO8), and is here quantified by whole blood chemiluminescence (CL) and 99mpertechnetate-imaging (99mTcO4-), and related to overt disease symptoms (the arthritis index). During the aqueous decay of K3CrO8 to chromate (VI), the chromium(V)-bound oxygen is released as superoxide, hydroxyl radicals, singlet oxygen and hydrogen peroxide, the same reactants, which are produced by activated phagocytes during inflammation. Reactive oxygen species (ROS) trigger the breakdown of the sulfhydryl-dependent antioxidant defence system and induce the nuclear factor kappa B-dependent expression of pro-inflammatory cytokines, which prime phagocytic NADPH oxidases to the enhanced production of ROS. During both the acute inflammatory response and the onset of the secondary response in non-injected paws, the phorbolester-stimulated ROS production of phagocytes was significantly enhanced (p < 0.001) and correlated well to the arthritis index (r = 0.797) and the uptake of 99mTcO4- into inflamed joints. Chromate(VI), formed during the decay of K3CrO8, contributes to the progression of arthritis by inhibition of glutathione reductase, thereby increasing intracellular H2O2 concentrations. In addition, Cr(VI) reduced to Cr(V) by ascorbate, catalyzes hydroxyl radical production in the presence of hydrogen peroxide. A stable loop forms, in which ROS, continuously produced by Cr(VI)/Cr(V) redox-cycling, drive the primary response into chronic self-perpetuating inflammation. We see the main application of K3CrO8-induced arthritis and its assessment by both 99mTcO4- imaging and chemiluminescent immunosensoring of phagocytic activity in unseparated blood as for the rapid screening of novel anti-rheumatic drugs and treatments.
