Transglutaminase-Mediated Semen Coagulation Controls Sperm Storage in the Malaria Mosquito

Abstract: Insect seminal fluid proteins are powerful modulators of many aspects of female physiology and behaviour including longevity, egg production, sperm storage, and remating. The crucial role of these proteins in reproduction makes them promising targets for developing tools aimed at reducing the population sizes of vectors of disease. In the malaria mosquito Anopheles gambiae, seminal secretions produced by the male accessory glands (MAGs) are transferred to females in the form of a coagulated mass called the mating plug. The potential of seminal fluid proteins as tools for mosquito control demands that we improve our limited understanding of the composition and function of the plug. Here, we show that the plug is a key determinant of An. gambiae reproductive success. We uncover the composition of the plug and demonstrate it is formed through the cross-linking of seminal proteins mediated by a MAG-specific transglutaminase (TGase), a mechanism remarkably similar to mammalian semen coagulation. Interfering with TGase expression in males inhibits plug formation and transfer, and prevents females from storing sperm with obvious consequences for fertility. Moreover, we show that the MAG-specific TGase is restricted to the anopheline lineage, where it functions to promote sperm storage rather than as a mechanical barrier to re-insemination. Taken together, these data represent a major advance in our understanding of the factors shaping Anopheles reproductive biology.
Linear-Time Pointer-Machine Algorithms for Path-Evaluation Problems on Trees and Graphs

Computer Science , 2002,
Abstract: We present algorithms that run in linear time on pointer machines for a collection of problems, each of which either directly or indirectly requires the evaluation of a function defined on paths in a tree. These problems previously had linear-time algorithms but only for random-access machines (RAMs); the best pointer-machine algorithms were super-linear by an inverse-Ackermann-function factor. Our algorithms are also simpler, in some cases substantially, than the previous linear-time RAM algorithms. Our improvements come primarily from three new ideas: a refined analysis of path compression that gives a linear bound if the compressions favor certain nodes, a pointer-based radix sort as a replacement for table-based methods, and a more careful partitioning of a tree into easily managed parts. Our algorithms compute nearest common ancestors off-line, verify and construct minimum spanning trees, do interval analysis on a flowgraph, find the dominators of a flowgraph, and build the component tree of a weighted tree.

Abstract: dership communication styles: a descriptive analysis of health care professionals Original Research (5171) Total Article Views Authors: Rogers R Published Date June 2012 Volume 2012:4 Pages 47 - 57 DOI: http://dx.doi.org/10.2147/JHL.S30795 Received: 11 February 2012 Accepted: 04 April 2012 Published: 26 June 2012 Rebekah Rogers School of Communication, East Carolina University, NC, USA Abstract: The study of leadership in health care is important to examine for many reasons. Health care leaders will inevitably have an impact on the lives of many people, as individuals rely on physicians and nurses during some of the most critical moments in their lives. This paper presents a broad overview of a research study conducted over the past year and highlights its general conclusions. In this study, I examined the leadership styles of health care administrators and those of physicians and nurses who chair departments. Thorough analysis yielded three clear themes: viewpoints on leadership, decision making, and relationships. Physicians' viewpoints on leadership varied; however, it was assumed that they knew they were leaders. Nurses seemed to be in a category of their own, in which it was common for them to use the term “servant leadership.” Results from the hospital administrators suggested that they were always thinking “big picture leadership.” Leadership is a working component of every job and it is important for people to become as educated as possible about their own communication style.

Implementing and managing self-management skills training within primary care organisations: a national survey of the expert patients programme within its pilot phase
Victoria Lee, Anne Kennedy, Anne Rogers
Implementation Science , 2006, DOI: 10.1186/1748-5908-1-6
Abstract: The NHS' official Expert Patients Programme website presently states that, "Pilot EPP courses began at 26 NHS PCT sites across England in May 2002, and by May 2004 approximately 300 PCTs had either actively implemented pilot courses or had committed to joining. The majority of PCTs are now coming to the end of the pilot phase, with many implementing plans to make EPP sustainable for the long-term." The NHS website heralds the pilot "a success."A national, postal survey of PCT EPP Leads was undertaken in order to examine both the evolvement of EPP during its pilot stage and future plans for the programme. A questionnaire was sent out to the 299 PCTs known to have committed to the EPP pilot, and an excellent 100% response rate was obtained over a 3-month period (April-July 2005). One marker of success of the Expert Patients Programme implementation is the actual running of courses by the Primary Care Trusts. This paper explores the extent to which the implementation of the pilot can indeed be viewed as a "success," primarily in terms of the number of courses run, and considers the extent to which PCTs have carried out all that they were committed to do. Findings suggest that the more time an EPP Lead dedicates to the Programme, the more likely it is that EPP has run successfully in the past, and the more likely it is that it will continue to run successfully in the future. Other factors indicating future EPP success include collaborating across PCTs to share co-ordinators, tutors, and funding.The United Kingdom (UK) Labour government has introduced a wide programme of reform for the prevention and management of chronic conditions [1]. One of the key areas identified for action relates to the promotion of self-care. Self-care skills training has increasingly been seen as an effective strategy for improving the quality of life and health outcomes for people living with long-term conditions. Whilst the running of self-care skills training within the voluntary sector in t
Continuity and change?: Exploring reactions to a guided self-management intervention in a randomised controlled trial for IBS with reference to prior experience of managing a long term condition

Abstract: Self-care interventions which have been evaluated using RCTs are currently being promoted as an effective strategy for improving quality of life, health and utilisation outcomes for individuals suffering from a range of long-term health conditions. Techniques such as cognitive re-structuring form the bases of self-management interventions and dedicated self-care education training has been attributed with beneficial outcomes including improving people's confidence in their ability to take care of themselves and engagement in collaborative shared decision making with health professionals [1-4]. The success of these interventions has been predicated in large on outcomes relating to: changes in behavior (the changing of diet, relaxation, and 'planned activity'); decreased utilization of health services; and attitude (self efficacy) or being better able to 'cope with symptoms'.Behaviorally orientated self-management educational programmes work include reference to stages, critical periods, developmental tasks and notions of maturation. Psychological outcome measures such as 'self-efficacy' are viewed as being enhanced through a number of mechanisms, the most effective of which is 'performance attainment' (i.e. actual experience of the success of actions) whilst depression and anxiety are viewed as impairing both self-efficacy beliefs and the ability to engage in those behaviours that might increase self-efficacy [5].Individuals entering self-management programmes as part of an RCT are viewed as having the potential to self-manage and learn new 'skills' once they have followed a formulaic. However, RCTs are not usually designed in a way which enables the distinction of the effects of past experience when testing new interventions and there is a tendency to treat the person as a blank sheet as far as prior patient experience and management of a long term condition is concerned. We know from the sociological literature on the experience of chronic illness that disruption t

Abstract: A nested attitudinal survey and qualitative study in sixteen primary care teams in north-west England. All practitioners participating in the trial (n = 74) were invited to complete a structured survey. Semi-structured interviews were undertaken with a purposive sub-sample of survey respondents, using a structured topic guide. Interview transcripts were used to identify key issues, concepts and themes, which were grouped to construct a conceptual framework: this framework was applied systematically to the data.Seventy (95%) of study participants responded to the survey. Survey respondents often found it stressful to work with patients with medically unexplained symptoms, though those who had received reattribution training were more optimistic about their ability to help them. Interview participants trained in reattribution (n = 12) reported that reattribution increased their confidence to practice in a difficult area, with heightened awareness, altered perceptions of these patients, improved opportunities for team-building and transferable skills. However general practitioners also reported potential barriers to the implementation of reattribution in routine clinical practice, at the level of the patient, the doctor, the consultation, diagnosis and the healthcare context.Reattribution training increases practitioners' sense of competence in managing patients with medically unexplained symptoms. However, barriers to its implementation are considerable, and frequently lie outside the control of a group of practitioners generally sympathetic to patients with medically unexplained symptoms and the purpose of reattribution. These findings add further to the evidence of the difficulty of implementing reattribution in routine general practice.Approximately 20% of patients present physical symptoms in primary care which general practitioners (GPs) are unable to explain by physical disease [1,2]. These patients frequently receive extensive investigation, referral and treatm

BMC Health Services Research , 2011, DOI: 10.1186/1472-6963-11-131
Abstract: Large scale comparative study employing qualitative data collection techniques: semi-structured interviews with key informants, task-groups, and workshops; framework analysis of qualitative data informed by Normalization Process Theory. Drawn from telecare services in community and domestic settings in England and Scotland, 221 participants were included, consisting of health professionals and managers; patients and carers; social care professionals and managers; and service suppliers and manufacturers.Key barriers to telecare integration were uncertainties about coherent and sustainable service and business models; lack of coordination across social and primary care boundaries, lack of financial or other incentives to include telecare within primary care services; a lack of a sense of continuity with previous service provision and self-care work undertaken by patients; and general uncertainty about the adequacy of telecare systems. These problems led to poor integration of policy and practice.Telecare services may offer a cost effective and safe form of care for some people living with chronic illness. Slow and uneven implementation and integration do not stem from problems of adoption. They result from incomplete understanding of the role of telecare systems and subsequent adaption and embeddedness to context, and uncertainties about the best way to develop, coordinate, and sustain services that assist with chronic disease management. Interventions are therefore needed that (i) reduce uncertainty about the ownership of implementation processes and that lock together health and social care agencies; and (ii) ensure user centred rather than biomedical/service-centred models of care.Since the beginning of the 1990s, telecare systems - information and communications technologies that link people (usually at home) to health and social care services - have been promoted as a technological solution for problems of equity and access to care, and as a means of support for
