The Origins, Governance and Social Structure of Club Cross Country Running in Scotland, 1885 – 1914

The study examines a particular aspect of the development of athletics in Scotland. The first organised clubs for the sole purpose of purely athletic competition in the contemporary sense, were cross country clubs known as harrier clubs. Through investigation of the origins, governance and the social structure of harriers clubs, the study connects these three fundamental themes in understanding sport within broader social historical study. In this study the origins of cross country running are set within a theoretical framework which recognises the nature of the urban and rural environments which defined the sport. The sport’s early growth and governance in Scotland is set alongside the broader ideological position of the ‘amateur’. Additionally, club organisation promoted the clubs as cultural institutions. Clubs served as a focus for male sociability and elevated the status of membership of the harriers. Membership meant more than just sporting engagement; it included social and civic standing. The purpose and function therefore of early clubs extended beyond participation. This study demonstrates how membership of cross country clubs conferred upon its members a status, establishing harriers clubs as important social institutions. This research shows how social networks within sport replicated society more broadly. The significance of the contribution of cross country clubs to the development of Scottish sporting culture is therefore implicit. Harriers clubs were the epitome of the complexity of sporting engagement representing both respectability and liminal behaviour

Re-implantation of cryopreserved ovarian cortex resulting in restoration of ovarian function, natural conception and successful pregnancy after haematopoietic stem cell transplantation for Wilms tumour

With the improvement of long-term cancer survival rates, growing numbers of female survivors are suffering from treatment-related premature ovarian insufficiency (POI). Although pre-treatment embryo and oocyte storage are effective fertility preservation strategies, they are not possible for pre-pubertal girls or women who cannot delay treatment. In these cases, the only available treatment option is ovarian cortex cryopreservation and subsequent re-implantation. A 32-year-old woman had ovarian cortex cryopreserved 10 years previously before commencing high-dose chemotherapy and undergoing a haematopoietic stem cell transplant for recurrent adult Wilms tumour, which resulted in POI. She underwent laparoscopic orthotopic transplantation of cryopreserved ovarian cortex to the original site of biopsy on the left ovary. She ovulated at 15 and 29 weeks post-re-implantation with AMH detectable, then rising, from 21 weeks, and conceived naturally following the second ovulation. The pregnancy was uncomplicated and a healthy male infant was born by elective Caesarean section at 36(+4) weeks gestation. This is the first report of ovarian cortex re-implantation in the UK. Despite the patient receiving low-risk chemotherapy prior to cryopreservation and the prolonged tissue storage duration, the re-implantation resulted in rapid restoration of ovarian function and natural conception with successful pregnancy

Cancer treatment and gonadal function : experimental and established strategies for fertility preservation in children and young adults

Copyright © 2015 Elsevier Ltd. All rights reserved.Preservation of gonadal function,is an important priority for the long-term health of cancer survivors of both sexes and all ages at treatment.. The loss of an opportunity for fertility is a prime concern in both male and female cancer survivors, however the endocrine consequences of gonadal damage are also central to long-term health and wellbeing. Some fertility preservation techniques, such as semen and embryo cryopreservation for the adult man and woman respectively, are established and successful and the recent development of oocyte vitrification has greatly improved the potential to cryopreserve unfertilised oocytes from women. Despite being recommended for all pubertal males, sperm banking is not universally practised in Paediatric Oncology centres, and there are very few ‘adolescent-friendly’ facilities. All approaches to fertility preservation have particular challenges in children and teenagers, including ethical, practical and scientific issues. For the young female, cryopreservation of ovarian cortical tissue with later replacement has now resulted in at least 35 live births, but is still regarded as experimental in most countries. For pre-pubertal males, testicular biopsy cryopreservation is offered in some centres, but it is unclear how that tissue might be used in the future, and to date there is no evidence that fertility can be restored. For both sexes these approaches require an invasive procedure, and there is an uncertain risk of tissue contamination in haematological and other malignancies. Decision making for all these approaches requires an assessment of the individual’s risk of loss of fertility, and is being made at a time of emotional distress. The development of this field requires better provision of information for patients and their medical teams as well as improvements in service provision, to match technical and scientific advances. Search strategy and selection criteria We searched Medline between Jan 1, 1990, and Sept 1, 2014, for reports published in English using the search terms “fertility preservation”, “cancer”, “childhood cancer”, “gonadotoxic”, and “cancer treatment” in several disjunctive and conjunctive combinations. We mainly selected publications in English from the past 5 years, but did not exclude older, significant publications. We also checked the reference lists of articles identified by this search strategy.PostprintPeer reviewe

Effect of the reproductive cycle on morphology and activity of the ovarian surface epithelium in mammals

The layer of cells lining the outer surface of the mammalian ovary, the ovarian surface epithelium (OSE), is a constant feature throughout the dynamic tissue remodeling that occurs throughout the reproductive cycle (follicle growth, ovulation, corpora lutea formation and pregnancy). Abnormal development of these cells is responsible for 90% of all epithelial ovarian cancers in women and epidemiological studies have shown that susceptibility to ovarian cancer is negatively correlated with increasing pregnancy. Little is known about how OSE cells are affected at each stage of the cycle, so the main aim of this study was to determine how the reproductive cycle affected proliferation and degeneration of OSE cells. This study utilised three animal models each with a different type of reproductive cycle: a mono-ovular seasonal breeder (Sheep), a mono-ovular polyoestrous breeder (Cow) and a poly-ovular non human primate (marmoset) to allow comparisons to be made. Comparison of OSE proliferative activity was made in sheep and marmoset at each stage of the cycle including pregnancy and anoestrous. The bovine model was used to investigate apoptotic cell death. Proliferative activity of somatic cells within the sheep ovary was monitored throughout the reproductive cycle by detection of cell cycle markers PCNA and Ki67 using immunohistochemistry. The pattern of OSE proliferation was correlated with the pattern of follicle development at each stage (sheep and marmoset). During pregnancy cell proliferation was significantly lower in OSE and in granulosa cells, reflecting a suppression of mature follicle development during these stages whereas in cycling animals proliferation was increased. Differences in OSE proliferation were observed in relation to the local underlying tissue environment in both sheep and marmoset. Epithelial cell rupture and regeneration enhanced the hormonal mitogenic action on epithelial cells, which showed highest proliferation over corpora lutea in each animal model. To test the hypothesis that these changes are mediated by hormones or growth factors ovine OSE cells were cultured and proliferative activity monitored after treatment with several factors: fetal calf serum (FCS), follicular fluid from follicles of varying sizes, corpora lutea extracts, recombinant human IGF-1, oestradiol and progesterone. IGF alone was demonstrated to have an affect on increasing proliferation of cultured OSE cells. Levels of FSHr and LHr were monitored by quantitative real- time PCR and it was demonstrated that the concentration of gonadotrophin receptors in OSE, increased prior to and after ovulation, at which time the in vivo OSE proliferation also peaked. The in situ apoptosis index was determined in bovine tissue using TUNEL throughout the regular cycle, and at mid and late-pregnancy stages. The results showed that pregnancy induced apoptotic activity in OSE cells and up regulated the tumour suppressor gene p53. Cultured bovine OSE cells also exhibited an increased level of apoptosis following progesterone treatment. Since p53/p53 gene expression in OSE over the corpora lutea producing progesterone also increased, this progesterone-mediated apoptosis may be mediated through an up-regulation of p53 synthesis. The effect of pregnancy and low production of gonadotrophins in the regulation of OSE cell morphology and activity was further investigated in the marmoset monkey (a non-human primate) treated with GnRH antagonist and infused with BrdU to monitor proliferative activity. OSE proliferation was correlated to ovarian events (follicular growth, ovulation and luteinization) and this was suppressed during pregnancy. Inhibition of gonadotrophin secretion by treatment with a GnRH antagonist also markedly inhibited OSE proliferation. Taken together these studies support the hypothesis that pregnancy and periods of anovulation reduce proliferation of OSE cells and alter the pattern of apoptotic cell death and that this effect is independent of species and reproductive pattern. Suppression of gonadotrophins and other growth factors during pregnancy could enhance p53-mediated apoptosis of damaged and mitogenic cells arising from repeated ovulations. This effect may partly explain why increasing number of pregnancies in woman reduces the chance of epithelial ovarian cancers.EThOS - Electronic Theses Online ServiceGBUnited Kingdo

The Reflective Sport and Exercise Science Practitioner

The development of reflective practitioners within the sport and exercise sciences and allied disciplines has started to gain prominence in discussions surrounding education, training, and practice in these fields. However, while the principles associated with doing reflective practice are becoming more widely discussed in the sport and exercise literature, debate concerning what it means to be a reflective practitioner remains limited. This has perhaps resulted in ongoing conceptual and applied considerations relating to the nature and importance of reflective practice, often leading to the promotion of, and engagement in, reflection that is overly technical, restricted, and compliant. Drawing on the perspectives of those who have contributed to this text, in this chapter we (editorial team) present a series of vignettes that offer accounts of what it means to be a reflective practitioner. In doing so, our aim is to allow the reader to immerse themselves within the contributors’ own experiences, perspectives and developmental journeys. Finally, we offer our own analytical summary of the contributors’ vignettes to draw together some of the common ideas and themes concerning the attitudes, skills, perspectives, and philosophy required by the reflective practitioner
