  1. 1. Optimization of b-value Acquisition and Parameter Estimation of Intravoxel Incoherent Motion Measurements

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Ivan Rashid; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Radiotherapy is commonly used for cancer treatment, given to approximately half of all cancer patients in Sweden. Despite its widespread usage, there is currently no non-invasive and reliable imaging method that can identify regions of radiation resistance. READ MORE

  2. 2. Hypoxia and hematopoietic stem cell control with the substance Adaptaquin : An evaluation of hematopoietic stem cell’s proliferation and differentiation in artificially induced hypoxia

    University essay from Malmö universitet/Institutionen för biomedicinsk vetenskap (BMV)

    Author : Jens Christiansen; [2023]
    Keywords : Adaptaquin; Flow cytometry; Hematopoietic stem cells; Hypoxia; Hypoxia inducible factor; Prolyl hydroxylase; Adaptaquin; Flödescytometri; Hematopoetiska stamceller; Hypoxi; Hypoxi inducerande faktor; Prolylhydroxylas;

    Abstract : Hematopoietic stem cells (HSCs) have historically been difficult to maintain ex vivo with many attempts to culture them in vitro by mimicking their natural biological environment. Providing a hypoxic environment is one way to achieve this goal and can be performed by using hypoxia stimulating compounds that inhibits the degradation of HIF1a which plays an important role in regulating hypoxia.

  3. 3. Förändringar i vilo-EKG hos hästar med dynamiska obstruktioner i de övre luftvägarna

    University essay from SLU/Dept. of Clinical Sciences

    Author : Maria Neil; [2022]
    Keywords : DDSP; felläge av mjuka gommen; upprättstående struplock; stämbandsförlamning; gomsegelhöjning; T-vågor; ventrikulära arytmier; endoskopi;

    Abstract : Hästar med övre luftvägsobstruktioner har visat sig vara predisponerade för utvecklingen av arytmier. Även om dessa är relativt vanligt förekommande i återhämtningsfasen är en ökad förekomst alarmerande då ventrikulära arytmier tros vara den vanligaste anledningen till de plötsliga dödsfall som sker på banorna.

  4. 4. Hypoxia-induced expression of HIF-1a and GPR30, in relation to survival, proliferation and apoptosis in MCF-7 and SkBr3 breast cancer cells.

    University essay from Lunds universitet/Läkarutbildningen

    Author : Hanna Chahin; Dianna Jazera; [2021]
    Keywords : hypoxia; breast cancer; GPR30 estrogen receptor; Medicine and Health Sciences;

    Abstract : Introduction: Hypoxia that accompanies tumor growth induces the expression of hypoxiainducible factor a (HIF-1a), in turn mediating the expression of other genes, including G protein-coupled receptor 30 (GPR30), to promote adaption to the hypoxic microenvironment and enable cell proliferation and survival. Nonetheless, this correlation has not been causally explained. READ MORE

  5. 5. Evaluation of transferability of Convolutional Neural Network pre-training with regard to image characteristics

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Fanny Ekblad Voltaire; Noah Mannberg; [2021]
    Keywords : ;

    Abstract : This study evaluates the impact of pre-training on a medical classification task and investigates what characteristics if images affect the transferability of learned features from the pre-training. Cardiotocography (CTG) is a combined electronic measurement of the fetal heart rate (FHR) and maternal uterine contractions during labor and delivery and is commonly analyzed to prevent hypoxia.
