    Here, we present the draft genome of Rhizobium rhizogenes strain ATCC 15834. The genome contains 7,070,307 bp in 43 scaffolds. R. rhizogenes, also known as Agrobacterium rhizogenes, is a plant pathogen that causes hairy root disease. This hairy root induction has been used in biotechnology for the generation of transgenic root cultures

    Understanding diversion programmes as an intervention for women with mental health issues: A realist review

    Get PDF
    Purpose: Women in prisons are known to suffer with more mental health difficulties and many experience challenges prior to incarceration. Diversion programmes are initiatives designed to divert people with pre-existing mental illness from the criminal justice system into mental health services. The variability of effectiveness of interventions makes realist approaches particularly appropriate for diversion programmes, and this paper presents the first realist review to be undertaken across the breadth of this topic. This realist review aimed to explain the successes, failures and partial successes of these programmes as an intervention to improve the outcomes of women offenders with mental health issues.// Methods: We conducted a realist review of published literature explaining the impact of diversion programmes on participants with mental health issues. Consultations with six specialists in the field were conducted to validate the principles and hypotheses about key dynamics for effective programmes. // Results: The review included 69 articles. We identified four essential principles, developed through thematic groupings of context-mechanism-outcome configurations, to articulate key drivers of the effectiveness of diversion programmes: coordination between services; development and maintenance of relationships; addressing major risk factors; and stabilisation through diversion programmes. // Conclusions: The behaviour of women offenders is driven by need, and the complex needs of this group require individualised plans that incorporate relationships as vehicles for support and change. Although there is a role for gender-specific interventions, it is not fully understood and further research is required. Implications for future interventions are discussed

    Large-Scale Wind-Tunnel Tests of a Wingless Vertical Take-Off and Landing Aircraft: Preliminary Results

    Large-scale wind-tunnel tests were made of a wingless vertical take-off and landing aircraft at zero sideslip to determine performance and longitudinal stability and control characteristics at airspeeds from 0 to 70 knots. Roll control and rudder effectiveness were also obtained. Limitations in the propulsion system restricted the lift for which level flight could be simulated to approximately 1500 pounds. Test variables with roll control and rudder undeflected were airspeed, vane setting, angle of attack, elevator deflection, and power. In most of the tests angle of attack, elevator, and power were varied individually while the other four parameters were held constant at previously determined values required for simulating trimmed level flight. The majority of the tests were made with power on and tail on at airspeeds between 20 and 70 knots. However, a limited number of data were obtained for the following conditions: (1) at zero velocity, horizontal tail on, power on; (2) at forward velocity, tail off and power on; and (3) at forward velocity, tail on, but with power off

    'Are we losing touch?' Mainstream parties' failure to represent their voters on immigration and its electoral consequences

    Get PDF
    In many advanced democracies, mainstream political parties have been disrupted either by the rise of new (populist) parties or by hostile takeovers. In this article we argue that immigration attitudes have had a powerful impact on the strategic environment of political parties and leaders. We show, based on evidence from a comparative study conducted by YouGov in spring of 2015, that immigration attitudes had, by that time, driven a wedge between mainstream parties - those that regularly play a role in government - and their partisans. This ‘immigration gap' opened up enormous space for new political movements to form, either inside existing parties or outside. Furthermore, we show that the representation gap on immigration issues is a relevant predictor of vote choice, so that parties are particularly likely to lose votes when they are more distant from their supporters on immigration

    Molecular basis of essential fructosuria: molecular cloning and mutational analysis of human ketohexokinase (fructokinase)

    Get PDF
    Essential fructosuria is one of the oldest known inborn errors of metabolism. It is a benign condition which is believed to result from deficiency of hepatic fructokinase (ketohexokinase, KHK, E.C.2.7.1.3). This enzyme catalyses the first step of metabolism of dietary fructose, conversion of fructose to fructose-1-phosphate. Despite the early recognition of this disorder, the primary structure of human KHK and the molecular basis of essential fructosuria have not been previously defined. In this report, the isolation and sequencing of full-length cDNA clones encoding human ketohexokinase are described. Alternative mRNA species and alternative KHK isozymes are produced by alternative polyadenylation and splicing of the KHK gene. The KHK proteins show a high level of sequence conservation relative to rat KHK. Direct evidence that mutation of the KHK structural gene is the cause of essential fructosuria was also obtained. In a well-characterized family, in which three of eight siblings have fructosurla, all affected individuals are compound heterozygotes for two mutations Gly40Arg and Ala43Thr. Both mutations result from G→A transitions, and each alters the same conserved region of the KHK protein. Neither mutation was seen in a sample of 52 unrelated control individuals. An additional conservative amino acid change (Val49lle) was present on the KHK allele bearing Ala43Th

    Friendsourcing Peer Support for Alzheimer’s Caregivers Using Facebook Social Media

    This research piloted an e-health intervention that used social media to friendsource peer support for Alzheimer’s disease (AD) caregivers. Friendsourcing is a variant of crowdsourcing. Crowdsourcing recruits online participants who share a characteristic that makes their volunteerism meaningful when they join to achieve an outcome. Friendsourcing recruits online participants who share membership in a social network that makes their volunteerism meaningful when they join to achieve an outcome. This article introduces our friendsourcing intervention research and examines the effects on the psychological well-being of AD caregivers. After a 6-week intervention, caregivers were found to have significantly decreased burden (Z = −2.01, p < .05) and perceived stress (Z = −2.95, p < .01). Emotional and informational support scores were significantly increased (Z = −2.32, p < .05). Qualitative data analysis of the intervention identified positive effects in new caregiving knowledge acquisition and application and reduced stress in the acceptance of the caregiving role. Joining social networks in support groups through friendsourcing was feasible for AD caregivers who were familiar with social media, and can provide another means of guiding the development of their personal support networks
