  1. 1. Refining the particulate matter airway deposition arising from indoor cooking-related biomass combustion for children in the Haramaya district in Ethiopia

    University essay from Lunds universitet/Ergonomi och aerosolteknologi

    Author : Kasper Malmborn; [2023]
    Keywords : Air pollution exposure; charcoal; wood; animal dung; low-income setting epidemiology; Technology and Engineering;

    Abstract : Background: Air pollution, a global issue affecting millions of individuals, is linked to adverse health effects on the respiratory system, but also to e.g., cancer and cardiovascular ailments. In low-income countries, cooking is often conducted by biomass-combustion, causing women and children to be exposed to high levels of indoor air pollution. READ MORE

  3. 2. Domain Adaptation for Multi-Contrast Image Segmentation in Cardiac Magnetic Resonance Imaging

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Thomas Proudhon; [2023]
    Keywords : Cardiac Magnetic Resonance Imaging; Deep Learning; Domain Adaptation; Unsupervised Segmentation; Image-to-image Translation;

    Abstract : Accurate segmentation of the ventricles and myocardium on Cardiac Magnetic Resonance (CMR) images is crucial to assess the functioning of the heart or to diagnose patients suffering from myocardial infarction. However, the domain shift existing between the multiple sequences of CMR data prevents a deep learning model trained on a specific contrast to be used on a different sequence. READ MORE

  4. 3. Development of a Compact Drive System for Total Artificial Heart

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Hossin Bakhtiari; [2023]
    Keywords : Total Artificial Heart; Drive System; Miniaturization; Electric Motor; Motor Performance Evaluation; Motor Selection; Totalt artificiellt hjärta; drivsystem; miniatyrisering; elektrisk motor; motorprestanda utvärdering; motor-urval;

    Abstract : Over eight decades of research into total artificial hearts (TAHs) has significantly contributed  to saving end-stage heart failure patients. However, at the current stage of development TAHs have several limitations, one of them being their bulkiness. READ MORE

  5. 4. Transcriptional basis of Huntington’s Disease: Gene expression analysis indicate increased immune responses in the brain and mitochondrial dysfunction in adipose tissues of HD model mouse

    University essay from KTH/Proteinvetenskap

    Author : Intisar Salim; [2023]
    Keywords : Huntington’s Disease; mRNA-seq; tissue specific gene expression; cerebrospinal fluid; biomarker; Huntingtons sjukdom; mRNA-seq; vävnadsspecifik genexpression; cerebrospinalvätska; biomarkör;

    Abstract : Huntingtons sjukdom (HD) är ett neurodegenerativt tillstånd som orsakas av mutationer i huntingtin gen (Htt), och resulterar till upprepade glutamin (polyQ) i Htt-proteinet. Muterad Htt kan inte vika sig ordentligt och börjar därför aggregera i celler. READ MORE

  6. 5. Deep learning for temporal super-resolution of 4D Flow MRI

    University essay from KTH/Matematik (Avd.)

    Author : Pia Callmer; [2023]
    Keywords : Temporal super-resolution; 4D Flow MRI; CNN; Artificial Intelligence; MRI; 4D flow; Temporal superupplösning; 4D flöde MRI; CNN; artificiell intelligens; MRI; 4D-flöde;

    Abstract : The accurate assessment of hemodynamics and its parameters play an important role when diagnosing cardiovascular diseases. In this context, 4D Flow Magnetic Resonance Imaging (4D Flow MRI) is a non-invasive measurement technique that facilitates hemodynamic parameter assessment as well as quantitative and qualitative analysis of three-directional flow over time.
