    [Extract] Striving to achieve a diverse and inclusive workplace has become a major goal for many organisations around the world. We recognise that not only is it the right thing to do, but that it is proven to achieve better outcomes in terms of innovation, reativity, science, and even financial success. However, sometimes the task of change can feel overwhelming and amorphous—what steps do we need to take to reach this goal? Within the disciplines of drone technology and drone science, let us start with the first rung on the ladder: gender-neutral languag

    Social Workers\u27 Perceptions of Family Preservation Programs

    The passage of the Adoptions and Safe Families Act of 1997, with its focus on child safety and concurrent planning, has presented family preservation workers with new challenges and new opportunities. Twenty volunteers from a large comprehensive social service agency were interviewed to determine their experiences with two models of family preservation—Multisystemic Therapy (MST) and Traditional Family Preservation Service (TFPS) or practice as usual. Workers from both programs were able to articulate values consistent with family preservation as important strengths of the programs— keeping families together and empowering families for example. Information from referring agencies was described as variable and not especially useful when working with seriously troubled families, especially as it related to risk and child safety. Both groups indicated that the jargon of family preservation had permeated their agencies, and that working with other agencies was at times a challenge, though for different reasons. Finally, despite some reservations about the effectiveness of short-term treatment with families that face serious challenges, both groups of workers were generally satisfied with family preservation as an approach to practice

    Expression of marA in Salmonella Typhimurium Exposed to Oxytetracycline in Vitro and in Vivo

    The recent discovery of ciprofloxacin-resistant Salmonella enterica serovar Typhimurium infections in humans has increased concern regarding the use of antimicrobials in food animals. It is because of this concern that many drugs are no longer available for use in food animal medicine, in an attempt to limit the spread of resistant organisms from animals to humans. The mar (multiple antibiotic resistance) system, originally found in E. coli, confers resistance to many different classes of drugs through efflux and porin resistance mechanisms, in response to unrelated compounds. The detection of this system in Salmonella Typhimurium, combined with the increasing resistance patterns and common transmission through improperly prepared food products, points to the possibility that antimicrobial use of any kind in food animals may lead to resistant infections in humans. In this research Salmonella Typhimurium was exposed to the commonly used antibiotic oxytetracycline both in vitro and in vivo, using a tissue chambVeterinary Pathobiolog

    Will d-amphetamine’s effect on impulsive choice be consistent when the environmental context changes by using decreasing delays to reinforcement?

    Impulsivity (choosing a smaller, more immediate reward over a larger, more delayed reward) and substance abuse are positively correlated. It is important to understand how factors like delay to reward and drug effects determine impulsive choice, which can be studied using animal models. This study evaluated impulsive choice in rats, where delays to the larger reward (three food pellets) were presented in decreasing order versus one food pellet delivered immediately. Then, effects of d-amphetamine were assessed. It was found that in three of four rats, d-amphetamine increased impulsive choice when the larger option was presented with decreasing delays. This effect is contrary to what has generally been found with increasing delays. Thus, environmental context can influence drug effects on impulsive choice

    Photoinactivation of bacteria attached to glass and acrylic surfaces by 405nm light : potential application for biofilm decontamination

    Attachment of bacteria to surfaces and subsequent biofilm formation remains a major cause of cross-contamination capable of inducing both food-related illness and nosocomial infections. Resistance to many current disinfection technologies means facilitating their removal is often difficult. The aim of this study was to investigate the efficacy of 405 nm light for inactivation of bacterial attached as biofilms to glass and acrylic. Escherichia coli biofilms (103–108 CFU mL1) were generated on glass and acrylic surfaces and exposed for increasing times to 405 nm light (5–60 min) at ca 140 mW cm2. Successful inactivation of biofilms has been demonstrated, with results highlighting complete/near-complete inactivation (up to 5 log10 reduction on acrylic and 7 log10 on glass). Results also highlight that inactivation of bacterial biofilms could be achieved whether the biofilm was on the upper “directly exposed” surface or “indirectly exposed” underside surface. Statistically significant inactivation was also shown with a range of other microorganisms associated with biofilm formation (Staphylococcus aureus, Pseudomonas aeruginosa and Listeria monocytogenes). Results from this study have demonstrated significant inactivation of bacteria ranging from monolayers to densely populated biofilms using 405 nm light, highlighting that with further development this technology may have potential applications for biofilm decontamination in food and clinical settings

Several authors have suggested that Grade 1 spondylolisthesis be considered a contraindication for interspinous device placement. Methods: We removed interspinous devices in six symptomatic Grade 1 spondylolisthesis patients and analyzed pertinent literature. Results: All six patients reported an improvement in symptoms following device removal and subsequent instrumented fusion. One patient who had not been able to walk due to pain regained the ability to walk. Several articles were identified related to spondylolisthesis and interspinous devices. Conclusions: Regarding patients receiving interspinous devices for symptomatic lumbar spinal stenosis, several high-quality studies have failed to demonstrate a statistical difference in outcomes between patients with or without Grade 1 spondylolisthesis. Nevertheless, surgeons should have a high degree of suspicion when considering use of interspinous devices in this patient population

    Sigma1 Targeting to Suppress Aberrant Androgen Receptor Signaling in Prostate Cancer.

    Suppression of androgen receptor (AR) activity in prostate cancer by androgen depletion or direct AR antagonist treatment, although initially effective, leads to incurable castration-resistant prostate cancer (CRPC) via compensatory mechanisms including resurgence of AR and AR splice variant (ARV) signaling. Emerging evidence suggests that Sigma1 (also known as sigma-1 receptor) is a unique chaperone or scaffolding protein that contributes to cellular protein homeostasis. We reported previously that some Sigma1-selective small molecules can be used to pharmacologically modulate protein homeostasis pathways. We hypothesized that these Sigma1-mediated responses could be exploited to suppress AR protein levels and activity. Here we demonstrate that treatment with a small-molecule Sigma1 inhibitor prevented 5α- dihydrotestosterone-mediated nuclear translocation of AR and induced proteasomal degradation of AR and ARV, suppressing the transcriptional activity and protein levels of both full-length and splice-variant AR. Consistent with these data, RNAi knockdown of Sigma1 resulted in decreased AR levels and transcriptional activity. Furthermore, Sigma1 physically associated with ARV7 and A
