Men’s experiences of a personalised, appearance-based, facial-morphing, safer drinking intervention

Risky alcohol consumption behaviours remain commonplace, representing a major threat to health and safety, and are especially evidenced by young university students. Consequently, new interventions targeting this high-risk group are required. The current study investigated young male university students’ experiences of a personalised, appearance-based, facial morphing, safer drinking intervention. Twenty-five male student participants were recruited, aged 18–34 years. Inductive thematic analysis of data gathered whilst participants were immersed in the intervention, and thereby exposed to alcohol-aged images of their own faces, produced four primary themes: alcohol as a threat to appearance and health, motivations to protect appearance, motivational aspects of the intervention, and proposed improvements and applications. The results of the current study suggested that participants expressed intentions towards healthier consumption/maintenance of already non-risky intake, supporting the potential of the facial-morphing appearance-based approach to address risky alcohol consumption, even in high-risk groups

Dimeticone 4% liquid gel found to kill all lice and eggs with a single 15 minute application

<p>Abstract</p> <p>Background</p> <p>Dimeticone 4% lotion is an effective and widely accepted treatment for head louse infestation. However, it is a highly mobile fluid that some people find difficult to apply and is mainly left on the hair for 8 hours or overnight. User preference is for a more manageable and viscous product that can be used with a short application time.</p> <p>Findings</p> <p>This proof of concept study in 41 people investigated dimeticone 4% liquid gel, a product that is easier to apply than the lotion, applied for 15 minutes on two occasions a week apart. We found that head lice were eliminated from all participants following the first application of product. We did not find lice of any stage on any participant during four post treatment assessments and particularly, unlike other treatments, no young nymphs on days 1 and 6 prior to the second treatment, indicating ovicidal as well as pediculicidal activity.</p> <p>Conclusions</p> <p>Dimeticone 4% liquid gel has demonstrated efficacy greater than other similar products and the evidence obtained indicates elimination of head louse infestation with a single 15 minute application.</p> <p>Trial registration</p> <p>Current Controlled Trials <a href="http://www.controlled-trials.com/ISRCTN59227204">ISRCTN59227204</a></p

Wheat responses to levels, sources and times of application of nitrogen.

Trial 90M055 Associated work: 90NO112, 105,104.111, 90MO53, 54,56 Location: Dandaragan This project characterizes the dynamics of nitrogen supply to a wheat crop at each of the sites on which various methods of making fertilizer recommendation were tested. It supposedly provides the optimum nitrogen fertilizer regime as well as detailed information on nitrogen supply and demand so that results can be made transferable to other situations. Trial 90MO56 Related trials: 90NO104, 105, 111, 112; 90MO53, 54,55 Tactical nitrogen application for wheat Location: Danaragan This project compares tactical and strategic methods for determining nitrogen requirements of wheat. The tactical methods depend on updating estimates of yield potential and nitrogen status of the crop as the season progresses

Directional wetting in anisotropic inverse opals

Porous materials display interesting transport phenomena due to the restricted motion of fluids within the nano- to micro-scale voids. Here, we investigate how liquid wetting in highly ordered inverse opals is affected by anisotropy in pore geometry. We compare samples with different degrees of pore asphericity and find different wetting patterns depending on the pore shape. Highly anisotropic structures are infiltrated more easily than their isotropic counterparts. Further, the wetting of anisotropic inverse opals is directional, with liquids filling from the side more easily. This effect is supported by percolation simulations as well as direct observations of wetting using time-resolved optical microscopy

Students’ experiences of a facial morphing intervention designed to encourage safer drinking

Objective: The study was designed to investigate women’s experiences of an age-appearance, facial-ageing, morphing intervention to show the effect of alcohol consumption on their skin. Design: Seventeen women aged 19-32 took part in the study, using individual sessions where they viewed the intervention. Main Outcome Measures: Participants were recorded during their viewing of the facial-ageing software, and the recordings of the sessions were then transcribed. Results: Transcripts were analysed using inductive thematic analysis. The women were shocked about the possible impact of alcohol consumption on their skin and appearance, and all of the women stated that the intervention had made them think about changing their alcohol consumption behaviours in the future, after viewing the images of themselves which were morphed to show the effects of both moderate and excessive alcohol consumption. Conclusion: The results are discussed in relation to suggestions for interventions aimed at women. It is concluded that appearance-based interventions do have a role to play with regards to alcohol consumption interventions

Platform-directed allostery and quaternary structure dynamics of SAMHD1 catalysis

SAMHD1 regulates cellular nucleotide homeostasis, controlling dNTP levels by catalysing their hydrolysis into 2’-deoxynucleosides and triphosphate. In differentiated CD4+ macrophage and resting T-cells SAMHD1 activity results in the inhibition of HIV-1 infection through a dNTP blockade. In cancer, SAMHD1 desensitizes cells to nucleoside-analogue chemotherapies. Here we employ time-resolved cryogenic-EM imaging and single-particle analysis to visualise assembly, allostery and catalysis by this multi-subunit enzyme. Our observations reveal how dynamic conformational changes in the SAMHD1 quaternary structure drive the catalytic cycle. We capture five states at high-resolution in a live catalytic reaction, revealing how allosteric activators support assembly of a stable SAMHD1 tetrameric core and how catalysis is driven by the opening and closing of active sites through pairwise coupling of active sites and order-disorder transitions in regulatory domains. This direct visualisation of enzyme catalysis dynamics within an allostery-stabilised platform sets a precedent for mechanistic studies into the regulation of multi-subunit enzymes

W(h)ither the academy? An exploration of the role of university social work in shaping the future of social work in Europe

A controversial proposal to pilot the training of child protection social workers through an intensive work-based route in England is being supported and funded by the UK Government. Frontline, the brainchild of a former teacher, locates social work training within local authorities (‘the agency’) rather than university social work departments (‘the academy’) and has stimulated debate amongst social work academics about their role in shaping the direction of the profession. As a contribution to this debate, this paper explores the duality of social work education, which derives its knowledge from both the academic social sciences and the experience of practice within social work agencies. While social work education has traditionally been delivered by the academy, this paper also explores whether the delivery of training in the allied professions of probation and nursing by ‘the agency’ is equally effective. Finally, this paper explores the Helsinki model which achieves a synergy of ‘academy’ and ‘agency’. It suggests that there are alternative models of social work education, practice and research which avoid dichotomies between the ‘academy’ and the ‘agency’ and enable the profession to be shaped by both social work academics and practitioners
