Patient-derived organoid culture for 3D culture of colorectal cancer, renal cancer and osteosarcomaJohansson, Seiko January 2019 (has links)
It is always important to choose appropriate anticancer drugs for cancer patients. At RCL, a division of Uppsala university hospital, drug resistance profiles of patients are evaluated by a cell viability assay called FMCA. However, the number of anticancer drugs that can be evaluated by the FMCA is dependent on the number of viable cancer cells from tissues that can be obtained from each individual patient. Therefore, improvement of cell viability methods is an important issue at RCL. This study was performed to improve the FMCA method by organoid culture from colorectal cancer, renal cancer and osteosarcoma to increase the number of cancer cells. As results, it was successful to expand cryopreserved patient cancer cells to organoids to acquire more cells than before expansion. Organoids showed rounded structure in microscopy images. Thereafter, FMCA was performed on organoids as well as on thawed cryopreserved cancer cells from the original sample. Those results showed that original cancer cells, cryopreserved original cancer cells and expanded organoids derived from those cryopreserved cells had similar resistance profiles. It was also discovered that the organoids secreted VEGF under the cultivation. From those results, it can be concluded that organoids are representative of the original cancer from the patients. It is however needed to improve organoid culture methods, and to further confirm organoids by protein expression analysis and DNA analysis.

The experience of qualified BME clinical psychologists : an interpretative phenomenological and repertory grid analysisOdusanya, Shamarel Olubunmi Elizabeth January 2017 (has links)
Aim: Knowledge of the experience of qualified BME clinical psychologists in clinical practice is currently lacking in the research literature. The aim of the current study was to explore the lived experience of qualified BME clinical psychologists currently employed in the National Health Service (NHS). By investigating this under-researched topic, the study hopes to shed light on the impact on clinicians' personal and professional identity of practicing within a profession that lacks cultural diversity. It is hoped that the results of this study will contribute to ongoing efforts to diversify the profession, improve our knowledge of the experience of BME groups in the helping profession and also challenge current misconceptions concerning the BME experience. Method: A mixed method qualitative approach was employed for this study. Repertory grids and semi-structured interviews were conducted with six female qualified BME clinical psychologists who are currently working in the NHS. They had been qualified between three and sixteen years. Their repertory grids were analysed using Idiogrid and their accounts were analysed using Interpretative Phenomenological Analysis (IPA). Results: Four master themes emerged from the analysis and were supported by the findings from the repertory grids showing that BME clinical psychologists feel that they stand out as different on account of their ethnic difference. The analytic procedure also highlighted how participants have to find a way to negotiate their cultural and professional values whilst also sitting with the uncertainty of their experiences in the profession. The final theme relates to the privilege that participants held in making it as a clinical psychologist. Implications: Initiatives to increase cultural competency and sensitivity need to be addressed by the profession. Efforts to increase ethnic diversity should be followed through to ensure practitioners are not left on the fringes of the profession on account of their minority ethnicity.

Inducing a Normal Phenotype in Breast Epithelial Cells Using a Three-Dimensional Basement Membrane Extract Culture System: A Study on the Reversion of CancerBooth, Ross H. 01 May 2009 (has links)
Experimentally, traditional developmental models and transgenic animals consistently underscore the importance of studying cell behavior in the correct tissue context. However, live animal experimentation is inherently complex, and systematic assessment of the effects of individual variables, such as cell shape and matrix compliance on cell behavior, is extremely difficult at best. Two-dimensional monolayer culture of key individual cell types has provided abundant, fundamental information on cell response, but cannot be used to show the normal phenotype of breast epithelial cells. Furthermore, their results often fail to translate into in vivo and clinical studies. It has been previously established that normal human breast epithelial cells can form their original phenotype as seen in vivo when embedded in or layered on reconstituted basement membrane extract. This phenotype is characterized as a single or double layer of polarized cells in acinar form with a lumen devoid of cells. Most malignant cell lines cultured under the same conditions exhibit severe morphological deformities, including colony overgrowth, luminal filling (hyperplasia), and resistance to apoptosis. It was hypothesized that malignant breast cells can be reverted to a normal phenotype through the manipulation of two factors: control of the environment via extra-cellular matrix proteins, and control of cellular pathways via signaling inhibitors. It was observed that high levels of epidermal growth factor resulted in disrupted multi-acinar formations. Inhibition of the protein complex known as mammalian target of rapamycin is currently being investigated as a potential method for cancer treatment. Exposure of rapamycin, mammalian target of rapamycin's primary inhibitor, led to decreased proliferation and increased caspase activity. Through the exposure to rapamycin in three-dimensional cultures, proliferation was reduced in malignant cells, while normal cells were not significantly affected. Unfixed fluorescent staining with ethidium bromide indicated the presence of luminal cell death. Increased structural organization was observed by immunofluorescent staining of F-actin and β-catenin. Through RT-PCR analysis, increased expression of a number of genes related to polarity and structural organization was detected in malignant cells exposed to rapamycin. Further study will be required to better characterize the reversion effects of rapamycin and its derivatives.

Community development and social regeneration: how the third sector addresses the needs of BME communities in post-industrial citiesWallace, James, Cornelius, Nelarine January 2010 (has links)
No / Interest in third sector organisations (TSOs) is growing as their role in addressing social regeneration, especially in urban environments, is regarded as crucial by governmental and supra-governmental organisations. The challenge is increased in multicultural environments, where those from ethnic minorities may struggle to participate in the mainstream economy and society more broadly. There is an assumption that TSOs make a positive contribution to the social good of the diverse communities and client groups that they serve. However, although there have been many studies of ethicality in commercial and public sector organisations, few focus on TSOs. Furthermore, black and minority ethnic (BME) TSOs, in particular face specific pressures, caught between the high expectations of their capacity to engage with diverse communities where the public sector has failed and, in common with all TSOs, the struggle to secure the resources necessary to manage their organisations and deliver front-line services. In this article, we investigate how implicitly ethicality is constructed in TSOs, including those with a primary mission to provide support for and services to BME communities. Building on information obtained for 305 TSOs in a post-industrial city we develop a structural equation model (SEM) in order to evaluate the relationships between elements that we argue comprise ethicality. We then assess the manner in which TSOs generally, and BME TSOs specifically, vary in the manner in which they communicate their ethical purpose and the outcomes of their actions.

Journeying towards Leadership: Personal Accounts of Experiences of Corrective Action by Managers in NHS OrganisationsAshraf, A., Archibong, Uduak E. January 2009 (has links)
No / The National Health Service (NHS) has historically undertaken initiatives to promote equality in employment as well programmes to develop and promote Black and Minority Ethnic (BME) staff. However, discrimination remains a feature of NHS employment practices and may help to explain the lack of BME staff at senior levels in the service. Despite having many initiatives BME staff are underrepresented in NHS senior management and at the top of each organisation, the management is almost always white. This paper will present findings from a case study on the experiences of corrective action by BME staff in senior/middle management positions. The paper will outline key messages and good practice to inform policy and practice.

Perceptions of dementia and use of services in minority ethnic communities: a scoping exerciseParveen, Sahdia, Peltier, C., Oyebode, Jan 09 June 2016 (has links)
Yes / Despite the rapidly ageing population and a predicted sevenfold increase in the prevalence of dementia in minority ethnic communities, people from these communities remain under-represented in specialist dementia services. Leventhal’s Model of Self-Regulation suggests perceptions ofillness facilitate help-seeking behaviours such as the use of services. Thisscoping exercise makes use of the model to explore perceptions ofdementia in British Indian, African and Caribbean, and East and CentralEuropean communities in the United Kingdom. Between August 2013and April 2014, culturally specific dementia awareness roadshows wereattended by people living with dementia, carers and members of thepublic. During the roadshows, 62 British Indian, 50 African and Caribbean, and 63 East and Central European attenders participated indiscussion groups and a dementia knowledge quiz. Thematic andframework analysis were conducted on the discussion group data. Threemain themes are presented: Perceptions of dementia, awareness ofdementia in the wider family and community, and awareness and use ofservices. The findings suggest that although groups attributed a biologicalbasis for memory loss, a number of misconceptions prevailed regardingthe cause of dementia. Groups also made use of religion, as opposed tomedical healthcare services, as a form of personal and treatment control. Seeking help from healthcare services was hindered by lack of awarenessof services, and culturally specific barriers such as language. The findingshave a number of implications for policy and practice including thedevelopment of public health interventions and the need to focus further on reducing barriers to accessing services.

The experiences of cognitive behavioural therapists when delivering manualised therapy to Black and Minority Ethnic clientsAkhtar, Nazreen January 2016 (has links)
Rationale: This study was conducted to help improve mental health care for Black and Minority Ethnic (BME) clients as previous research carried out in non-western countries has suggested that western-developed psychotherapies often need to be culturally adapted to become more effective in treating this client group. The aim of this study was to explore how CBT therapists deliver manualised CBT with BME clients and if they make any adaptations, how and to what extent are they implemented. Method: Interpretative Phenomenological Analysis (IPA) guided the conduct and analysis of one-to-one, semi-structured interviews with six CBT therapists working in an Improving Access to Psychological Therapies (IAPT) service. The inclusion criteria for participants was accreditation with the BABCP, completion of an IAPT programme CBT diploma and to be currently working in an IAPT service, at least two years experience as a CBT therapist and at least four cases of completed therapy with BME clients. Findings: Four master themes emerged (1) CBT is based on western principles, (2) The complex nature of CBT, (3) Changing practice of manualised CBT and (4) The influence of therapist factors. Conclusion: The participants experienced many issues in their practice of manualised CBT with BME clients which led them to make changes including adaptations to manualised CBT. They described their current practice as being integrative as they incorporated therapeutic approaches other than pure manualised CBT, making them more flexible and adaptable. The adaptations involved altering the cognitive and behavioural interventions to better suit the individual needs of the client. The adaptations took into account the client’s culture, religion, language, psychological mindedness, acculturation to their host country, education and age. The participants’ confidence in CBT and their self-identity as therapists also influenced their overall practice of therapy. Recommendations for practice are discussed in relation to therapeutic practice, training of therapists, supervision and policy makers.

The experience of being a trainee clinical psychologist from a black and minority ethnic group : a qualitative studyShah, Snehal January 2010 (has links)
Aim: The existing evidence-base indicates that the experience of being a Black and Minority Ethnic (BME) trainee clinical psychologist is under-researched. The aim of the current study was to capture the broader training experiences of BME trainee clinical psychologists. The impact of potential personal and professional experiences that may arise for BME trainee clinical psychologists may be important for course tutors and clinical supervisors to explore with them in relation to personal and professional development. Thus, it is hoped that the findings of the current study will raise an increased awareness within the clinical psychology training courses, of their needs, perspectives and experiences. Method: A qualitative approach was adopted for this study. Semi-structured interviews were conducted with nine BME trainee clinical psychologists. The accounts were analysed using IPA, which attempts to illuminate the lived experience of a phenomenon for small samples of individuals. Results: The analytic procedure highlighted five main themes which emerged from participants’ accounts: The hardship of not being White, The challenge of negotiating multiple identities, Challenges and dilemmas of highlighting race and culture issues, The versatility that comes with being a BME trainee and Finding connections and safe places. Implications: Current initiatives to attract more applicants from BME groups need to be considered in the context of wider structural experiences of power and difference in relation to race, ethnicity and culture that operate in the training arena. Courses need to explicitly state their commitment to supporting trainees from BME groups with regards to their experiences of difference. Emphasis should be placed on personal and professional development of all trainees and needs to include work on privilege, social disadvantage, and racism. Programmes should also undertake a commitment to training course staff and supervisors in relation to race issues in the context of training.
