  1. 1. The Balanced Electromagnetic Separation Transducer for Bone Conduction Audiometry and Hearing Rehabilitation

    Författare :Karl-Johan Fredén Jansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; retention magnet; bone vibrator; demagnetization; bone conduction; balanced electromagnetic separation transducer; magnetically induced torque; image artifact; magnetic resonance imaging;

    Sammanfattning : Hearing via air conduction (AC) and bone conduction (BC) are attributed to bethe natural ways of conducting sound to the cochlea. With AC hearing, air pressurevariations are transmitted to the cochlea via the ear canal, whereas with BChearing, sound vibrations are transmitted through the skull bone to the cochlea. LÄS MER

  2. 2. Microfluidic based isolation of circulating tumor cells from whole blood for cancer diagnostics

    Författare :Harisha Ramachandraiah; Aman Russom; Klas Hjort; KTH; []

    Sammanfattning : Detection of circulating tumor cells (CTC) in peripheral blood is indicative of early recognition of tumor progression and such an important biomarker for early diagnosis, staging, monitoring and prognosis of cancer. However, CTC are found in very low concentrations and reliable isolation of these rare cells is challenging. LÄS MER

  3. 3. Role of mitochondria in early molecular diagnosis and prognosis of cancer

    Författare :Yanni Li; Allmänmedicin och klinisk epidemiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancer; mtDNA copy number; mitochondrial-related nuclear genes; mtDNA mutations; diagnosis; prognosis; biomarker;

    Sammanfattning : Background:Earlier clinical detection of cancer may improve survival as well as offer opportunities for less invasive treatment options. This thesis explores whether the mitochondria and its related genes in the nuclear genome can be used as novel methods for the diagnosis and prognosis of cancers. LÄS MER

  4. 4. Prostate Cancer Diagnosis : experimental and Clinical Studies With HRMAS NMR Spectroscopy

    Författare :Katarina Stenman; Katrine Åhlström-Riklund; Anders Bergh; Peter Lundberg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer; PCa; HRMAS NMR; MRSI; metabolomics; Gleason score; citrate; inositol; choline; Krebs cycle; PUFA; omega-6; omega-3; Diagnostic radiology; Diagnostisk radiologi; Radiology; radiologi;

    Sammanfattning : A few abnormal cells found in a small piece of prostate tissue are most consequential for a man’s future. The prevalence of prostate cancer (PCa) is increasing globally. LÄS MER

  5. 5. Combining Shape and Learning for Medical Image Analysis

    Författare :Jennifer Alvén; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; feature-based registration; convolutional neural networks; conditional random fields; medical image segmentation; random decision forests; machine learning; multi-atlas segmentation; medical image registration; shape models;

    Sammanfattning : Automatic methods with the ability to make accurate, fast and robust assessments of medical images are highly requested in medical research and clinical care. Excellent automatic algorithms are characterized by speed, allowing for scalability, and an accuracy comparable to an expert radiologist. LÄS MER
