Selection for Field Survival Increases Freezing Tolerance in Festulolium

Festulolium (Festulolium braunii K.A.) is marginally adapted to the north central and northeastern USA and southern Canada. The purpose of this study was to evaluate four festulolium populations selected for field survival under harsh winter conditions for their freezing tolerance in controlled environments. Progenies of all four populations showed some improvement in freezing tolerance compared to their parents. Improvements were dependent on the temperature at which measurements were made and varied among germplasms. Improvements were manifested in both decreased plant mortality and decreased injury to surviving plants. Genetic variation for freezing tolerance appears to be a viable mechanism for enhancing field survival of festulolium

Participatory Development of a Forage Grass Cultivar

Perennial forage grasses exist in both nature and agriculture as a highly heterogeneous mixture of genotypes. Extreme environments, fluctuating environments, and severe managements can impose selection pressures that will result in loss of unadapted genotypes. Mortality of unadapted genotypes leads to dominance of fewer highly adapted genotypes which may be useful as superior germplasm in other similar environments

A prospective trial of tacrolimus (FK 506) in clinical heart transplantation: Intermediate-term results

Between January 1, 1989, and December 31, 1994, we have treated 122 primary heart recipients with FK 506 (group I) and 121 with cyclosporine (group II). Fifty patients in the cyclosporine (CyA) group received no lympholytic induction (CyA alone) and 71 others received lympholytic induction with either rabbit antithymocyte globulin or OKT3 (CyA+LI). The mean follow-up was longer in the FK 506 group than in the CyA groups (3.2 ± 1.3 vs 2.3 ± 1.8 years; p < 0.01). Patient survival did not differ on the basis of the type of immunosuppression used. At 3 months after transplantation, the freedom from rejection in the FK 506 group was higher than that of the CyA-alone group (47% vs 22%, p < 0.01) but similar to that of the CyA+LI group (47% vs 53%). The linearized rejection rate (episodes/100 patient-days) of the FK 506 group (0.09 episodes) was lower (p < 0.05) than that of the CyA-alone group (0.26) and the CyA+LI group (0.13). The requirement for pulsed steroids to treat rejection was less in common in the FK 506 group than in either CyA group. Eighteen patients in the CyA group had refractory rejections; all resolved with FK 506 rescue. Two patients in the FK 506 group had refractory rejection that resolved with total lymphoid irradiation (n = 1) and methotrexate therapy (n = 1). Patients receiving FK 506 had a lower risk of hypertension and required a lower dose of steroids. Although the mean serum creatinine concentration at 1 year was higher in the FK 506 group, this difference disappeared after 2 years. No patients required discontinuation of FK 506 because of its side effects. Our intermediate-term results indicate that FK 506 compares favorably with CyA as a primary immunosuppressant in heart transplantation

Freezing of ridges and water networks preserves the Gamburtsev Subglacial Mountains for millions of years

Once an ice sheet grows beyond a critical thickness, the basal thermal regime favors melting and development of subglacial water networks. Subglacial water is necessary for bedrock erosion, but the exact mechanisms that lead to preservation of subglacial topography are unclear. Here we resolve the freezing mechanisms that lead to long-term, high-altitude preservation across the Gamburtsev Subglacial Mountains in East Antarctica. Analyses of a comprehensive geophysical data set reveal a large-scale water network along valley floors. The ice sheet often drives subglacial water up steep topography where it freezes along high ridges beneath thinner ice. Statistical tests of hypsometry show the Gamburtsevs resemble younger midlatitude mountains, indicating exceptional preservation. We conclude that the Gamburtsevs have been shielded from erosion since the latest Eocene (∼34 Ma). These freezing mechanisms likely account for the spatial and temporal patterns of erosion and preservation seen in other glaciated mountain ranges

Potassium‐ion‐selective fluorescent sensors to detect cereulide, the emetic toxin of B. cereus, in food samples and HeLa cells

We report the development of new chemical probes for cereulide, a toxic metabolite produced by specific strains of Bacillus cereus, through displacement of potassium cations from a preformed specific complex and a subsequent change in the fluorescence emission. For this purpose, we designed fluorescent probes for potassium cations that were suitable for displacement assays with cereulide from organic extracts. The fluorescence detection of natural cereulide in rice samples was achieved by using synthetic cereulide as a reference and a potassium fluorescent reporter, and this was found to be useful as a portable and fast method for the in situ detection of cereulide in food extracts. To study the fate of cereulide in live cells, we designed a procedure that was suitable for live‐cell microscopy imaging of HeLa cells by comparing the cellular location of the potassium fluorogenic probe, which stained intracellular endolysosomes, in the absence and presence of cereulide; we concluded that in the presence of cereulide, the fluorescence of the probe was decreased because of complexation of the potassium ions by cereulide.Ministerio de Econom&a y Competitividad, Spain (Projects CTQ2015-71353-R and AES-PI16/000496), Junta de Castilla y Lejn, Consejer&a de Educaci jn y Cultura y Fondo Social Europeo (Project BU232U13), and the European Commission, Seventh Framework Programme (Project SNIFFER FP7-SEC-2012–312411

Poles apart: Does the export of mental health expertise from the Global North to the Global South represent a neutral relocation of knowledge and practice?

© 2015 Foundation for the Sociology of Health & Illness.The World Health Organization's Mental Health Action Plan 2013-2020 identifies actions for all member states to alleviate the global burden of mental ill health, including an obligation for mental healthcare to be delivered in a 'culturally appropriate' manner. In this article we argue that such a requirement is problematic, not least because such pronouncements remain framed by the normative prepositions of Western medical and psychological practice and their associated ethical, legal and institutional standpoints. As such, when striving to export Western mental health expertise, different paradigms for evidence will be necessary to deliver locally meaningful interventions to low and middle income countries. Our discussion highlights a number of philosophical concerns regarding methodologies for future research practice, including those relating to representation and exclusion in the guise of epistemic injury, presumptive methodologies arising from Western notions of selfhood, and related ethical issues

"They brought you back to the fact you're not the same": Sense of self after traumatic brain injury

This paper considers contexts following traumatic brain injury, exploring what may be at stake when dominant expectations predict a ‘lost’ or ‘broken’ self. I explore stories co-constructed with one young man and his mother to illustrate their personal and intersubjective understandings of identity, at times conflicting, within family interactions and when encountering normative practices of neurorehabilitation clinicians. The ower relations portrayed confront this man’s narrative attempts to align his present and pre-injury self, including standard assessments delineating change, administered by healthcare professionals. I consider a need for greater attention to interaction-generated disruption to sense of self, wthin contemporary conceptualisations of ‘person-centred care’

Cross-national mixed methods comparative case study of recovery-focused mental health care planning and coordination in acute inpatient mental health settings (COCAPP-A)

Background: Serious concerns have been identified in relation to care planning, patient involvement and consent to treatment in mental health wards, including for those patients detained under the Mental Health Act. Further evidence is needed to develop care planning interventions that embed dignity, recovery and participation for all people using inpatient mental health care. Design: We propose to undertake a cross-national comparative study of recovery-focused mental health care planning in inpatient settings. This two-phase exploratory mixed methods study will produce theory and empirical evidence to complement that developed in our current study of community mental health services to inform a future whole systems intervention study. The study is guided by a theoretical framework emphasising the connections between different 'levels' of organisation (macro/meso/micro). In phase 1 we study the macro-level through the comparative analysis of English and Welsh policy contexts. In phase 2 concurrent quantitative and qualitative data will be collected at 6 NHS Trust/Health Board case study sites (meso-level) and within each site, a single micro-level mental health ward will be selected to provide in-depth qualitative data related to care planning processes. Phase 1: We will extend our current meta-narrative mapping review (Wong et al 2013) of English and Welsh policies and the international literature on personalised recovery-oriented care planning and coordination in community settings to include inpatient settings. We will provide a review of evidence that is useful, rigorous and relevant for service providers and decision-makers and to inform Phase 2. Phase 2: We are employing a concurrent transformative mixed methods approach with embedded case studies (Creswell 2009: 215). We will conduct six in-depth meso-level case study investigations across contrasting NHS Trusts in England (n=4) and Local Health Boards in Wales (n=2), selected to reflect variety in geography and population and include a mix of rural, urban and inner city settings providing routine inpatient care. A large sample of service users (total n=300), inpatient staff (n=300) and informal carers (n=150) will be surveyed about perceptions of acute mental health care and care planning, recovery oriented practices, therapeutic relationships and empowerment using validated questionnaires. Documents and interviews with managers, consultant psychiatrists, ward staff and informal carers (n=60) will also be generated relating to local contexts, policies and practices. In each site we will also select a single inpatient ward and conduct a series of case studies embedded within each organisational case study, to explore care planning in detail. We will invite a sample of service users (total n=36) to participate in in-depth interviews about care planning and structured narrative reviews of their care plans; undertake a structured review of anonymised care plans for a further sample (n=60) of consecutively discharged patients; and conduct observation of care planning processes (n= 18). Framework method will be employed to integrate and compare textual and statistical summaries of qualitative and quantitative analyses within each case study site, informed by the theoretical framework focused on recovery and personalisation. Armed with our set of six within-case analyses we will then conduct a cross-case analysis to draw out key findings from across all sites

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead
