    Evidence for niche differentiation in the environmental responses of co-occurring mucoromycotinian fine root endophytes and glomeromycotinian arbuscular mycorrhizal fungi

    Fine root endophytes (FRE) were traditionally considered a morphotype of arbuscular mycorrhizal fungi (AMF), but recent genetic studies demonstrate that FRE belong within the subphylum Mucoromycotina, rather than in the subphylum Glomeromycotina with the AMF. These findings prompt enquiry into the fundamental ecology of FRE and AMF. We sampled FRE and AMF in roots of Trifolium subterraneum from 58 sites across temperate southern Australia. We investigated the environmental drivers of composition, richness, and root colonization of FRE and AMF by using structural equation modelling and canonical correspondence analyses. Root colonization by FRE increased with increasing temperature and rainfall but decreased with increasing phosphorus (P). Root colonization by AMF increased with increasing soil organic carbon but decreased with increasing P. Richness of FRE decreased with increasing temperature and soil pH. Richness of AMF increased with increasing temperature and rainfall but decreased with increasing soil aluminium (Al) and pH. Aluminium, soil pH, and rainfall were, in decreasing order, the strongest drivers of community composition of FRE; they were also important drivers of community composition of AMF, along with temperature, in decreasing order: rainfall, Al, temperature, and soil pH. Thus, FRE and AMF showed the same responses to some (e.g. soil P, soil pH) and different responses to other (e.g. temperature) key environmental factors. Overall, our data are evidence for niche differentiation among these co-occurring mycorrhizal associates

    Rogue diva flows: Aoi Sola's reception in the Chinese media and mobile celebrity

    Theorizations of celebrity often contend with questions of the constructed nature of star persona. This is more so the case when discussing divas in Japan, as they are subject to a wide range of gender regimes that mould the ways in which their persona is produced and consumed. Contemporary forms of transnationalism in East Asia, however, have created media flows and fan bases that provide new opportunities for Japanese female celebrities to re-construct their star personas, transcending their celebrity status in Japan. Focusing on the case of Aoi Sola, a Japanese adult video actress turned celebrity, this article demonstrates how transnational East Asian flows problematize our static theorization of celebrity. Sola's interactions with her Chinese social media fan base have afforded her a cosmopolitan persona that has been celebrated as a cultural bridge between China and Japan. At the same time, her star persona leaves her vulnerable to re-inscriptions into transnational politics as played out in everyday media flows. This dynamic is best demonstrated in Sola's attempts to quell anti-Japanese sentiment in China as well as in her efforts to reinscribe her star persona using nostalgic associations of cultural similarity and a shared past. Based on analyses of Sola's celebrity trajectory from adult video to online Chinese mediascape Diva, this article suggests that contemporary star persona status is better understood in terms of gender, movement and ‘meshworks’

    Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries

    Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P < 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely

    “Evidence of the Recent Creation” - The Creator Revealed, part 6

    Living things provide abundant evidence of their relatively recent creation. Claims that life, and death, are billions of years old exploit the fact that we can’t do time travel to see if they are true. All we can do is consider the record of the past we have in God’s Word and in His creation. Join us as we examine just a little of the clear evidence that life on Earth is thousands rather than millions of years old

    DNA is amazing, but what exactly is it? What does it do in every living thing? Why is DNA just the right material for the function it performs? Why does just about everyone who studies it acknowledge that DNA at least looks designed? Are there good reasons for Darwinists to deny that DNA is evidence of design? What does DNA tell us about the Creator who wrote out the instructions for life in this remarkable molecule

    Scientists are just beginning to understand the structure and function of minute machines that are essential for life. Inside cells, these submicroscopic motors, generators and other machines operate by the same principles as the machines we are familiar with, only at much higher efficiency and within incredibly tight tolerances. What best accounts for these engineering marvels
