  1. 6. Imaging diffusional variance by MRI [public] : The role of tensor-valued diffusion encoding and tissue heterogeneity

    Author : Filip Szczepankiewicz; Lund Medicinsk strålningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Diffusion MRI provides a non-invasive probe of tissue microstructure. We recently proposed a novel method for diffusion-weighted imaging, so-called q-space trajectory encoding, that facilitates tensor-valued diffusion encoding. READ MORE

  2. 7. Functional and Molecular Characterization of BRCA1 and BRCA2 Associated Breast Cancer

    Author : Johan Vallon-Christersson; Bröstcancer-genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; onkologi; cancer; Cytologi; cancerology; Cytology; BioArray Software Environment; BASE; Software; Open-source; Copy number; Gene expression; Microarray; BRCA2; BRCA1; Breast cancer; Hereditary cancer; oncology;

    Abstract : This doctoral dissertation is based on five appended papers primarily concerned with three main topics, namely: the functional characterization of specific and clinically relevant perturbations found in BRCA1 ? one of the major breast cancer susceptibility genes; the use of microarray technologies for molecular characterization of hereditary breast tumor samples from a genomic perspective; and finally, the development of software to address some of the logistical problems of data analysis and management that arise when utilizing microarrays. Results obtained from the work presented herein demonstrate the following: that transcription az says can aid in the characterization of C-terminal missense mutations but that it may not be possible to unambiguously characterize variants with a yeast-based assay alone; that a naturally occurring C-terminal germline mutation in BRCA1 encodes a protein with apparent temperature-dependant functional properties; that open-source software can provide comprehensive solutions to meet data management needs of microarray experimenters; that BRCA1 and BRCA2 associated breast tumors exhibit markedly different copy number aberrations when compared to each other as well as to sporadic tumors; and that gene expression profiling in BRCA1 and BRCA2 associated breast tumors reveals specific gene expression patterns.

  3. 8. Predicting Normal Tissue Complications after External Beam Radiation Therapy

    Author : Caroline Olsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NTCP; fractionation effects; radiobiological modelling; pubic bone pain;

    Abstract : Although modern external beam radiation (EBRT) therapy has the ability to conform the dose tightly around the volume to be treated, unwanted irradiation to surrounding normal tissue is still a problem. The probability of a side effect arising in normal tissue after EBRT is commonly modelled by an s-shaped dose-volume response curve where dose or volume are plotted against response (i. READ MORE

  4. 9. Novel treatments of glioblastoma in experimental models

    Author : Karolina Förnvik; Neurokirurgi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Experimental glioma models; Glioblastoma; Complement system; C1 esterase inhibitor; ITPP; CRP; Glioma cells;

    Abstract : One of the major problems with malignant brain tumours, such as glioblastoma multiforme, is that despite being able to remove the major bulk of the tumour through surgery and treating the patients with chemotherapy and radiotherapy, we know that tumour cells have already spread throughout the brain. Furthermore, we now know that the glioblastoma cells effectively suppress the patients’ own anti-tumour response. READ MORE

  5. 10. Meta-analysis of randomized clinical evidence of chemotherapy, radiotherapy and endocrine therapy in breast cancer

    Author : Antonis Valachis; Vassilios Georgoulias; Dimitros Mavroudis; Gregory Chouverakis; Örebro universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast cancer; Meta -analysis; Bisphosphonates; Bevacizumab; Trastuzumab; Fulvestrant;

    Abstract :  Breast cancer is the most frequently diagnosed cancer and the leading cause of cancer death in females worldwide. Despite the growing body of randomized controlled trials (RCTs) regarding the use of various treatment strategies (chemotherapy, endocrine therapy, radiotherapy) in breast cancer, the efficacy of some strategies remains unclear and questionable.
