    Background: Prompt treatment following Transient Ischemic Attack (TIA) can reduce the risk of subsequent stroke and disability. However, many patients delay in making contact with medical services. This study aimed to explore TIA patients’ accounts of delay between symptom onset and contacting medical services including how decisions to contact services were made and the factors discussed in relation to delay. Methods: Twenty interviews were conducted with TIA patients in England. Using a previous systematic review as an initial framework, interview data were organised into categories of symptom recognition, presence of others and type of care sought. A thematic analysis was then conducted to explore descriptions of care-seeking relevant to each category. Results: Delay in contacting medical services varied from less than an hour to eight days. Awareness of typical stroke symptoms could lead to urgent action when more severe TIA symptoms were present but could lead to delay when experienced symptoms were less severe. The role of friends and family varied widely from deciding on and enacting care-seeking decisions to simply providing transport to the GP practice. When family or friends played a greater role, and both made and enacted care-seeking decisions, delays were often shorter, even when patients themselves failed to identify symptoms. Healthcare professionals also impacted on patients ’ care-seeking with greater delays in seeking further care for the same episode described when patients perceived a lack of urgency during initial healthcare interactions

    Cellular patterning of Arabidopsis roots under low phosphate conditions

    Phosphorus is a crucial macronutrient for plants playing a critical role in many cellular signaling and energy cycling processes. In light of this, phosphorus acquisition efficiency is an important target trait for crop improvement, but it also provides an ecological adaptation for growth of plants in low nutrient environments. Increased root hair density has been shown to improve phosphorus uptake and plant health in a number of species.In several plant families, including Brassicaceae, root hair bearing cells are positioned on the epidermis according to their position in relation to cortex cells, with hair cells positioned in the cleft between two underlying cortex cells. Thus the number of cortex cells determines the number of epidermal cells in the root hair position. Previous research has associated phosphorus-limiting conditions with an increase in the number of cortex cell files in Arabidopsis thaliana roots, but they have not investigated the spatial or temporal domains in which these extra divisions occur or explored the consequences this has had on root hair formation.In this study, we use 3D reconstructions of root meristems to demonstrate that the anticlinal cell divisions seen under low phosphate are exclusive to the cortex. When grown on media containing replete levels of phosphorous, Arabidopsis thaliana plants almost invariably show 8 cortex cells; however when grown in phosphate limited conditions, seedlings typically develop 12-16 cortex cells, resulting in a significant increase in the number of epidermal cells at hair forming positions. These anticlinal divisions occur within the initial cells and can be seen within 24 hours of transfer of plants to low phosphorous conditions. We show that these changes in the underlying cortical cells feed into epidermal patterning by altering the regular spacing of root hairs

    Full 0ω0\hbar\omega shell model calculation of the binding energies of the 1f7/21f_{7/2} nuclei

    Binding energies and other global properties of nuclei in the middle of the pfpf shell, such as M1, E2 and Gamow-Teller sum rules, have been obtained using a new Shell Model code (NATHAN) written in quasi-spin formalism and using a jjj-j-coupled basis. An extensive comparison is made with the recently available Shell Model Monte Carlo results using the effective interaction KB3. The binding energies for -nearly- all the 1f7/21f_{7/2} nuclei are compared with the measured (and extrapolated) results.Comment: 7 page

Methods: We systematically searched eight databases for qualitative research reporting women’s experiences of receiving a false-positive screening test result. Two reviewers independently screened articles. Eight papers reporting seven studies were included. Study quality was appraised. Data were thematically synthesised. Results: Women passively attended screening in order to prove their perceived good health. Consequently, being recalled was unexpected, shocking and disempowering: women felt without options. They endured great uncertainty and stress and sought clarity about their health (e.g. by scrutinising the wording of recall letters and conversations with healthcare professionals). Their result was accompanied by relief and welcome feelings of certainty about their health, but some received unclear explanations of their result, contributing to lasting breast cancer-related worry and an ongoing need for further reassurance. Conclusion: The organisation of breast screening programmes may constrain choice for women: they became passive recipients. The way healthcare professionals verbally communicate results to women may contribute to lasting breast cancer-related worry. Women need more reassurance, emotional support and answers to their questions before and during screening assessment, and after receiving their result
