  1. 16. Pharmacometric Investigations of Prediction Precision and Advances of Models for Composite Scale Data

    Författare :Gustaf Wellhagen; Maria C. Kjellsson; Bengt Hamrén; Per Olsson Gisleskog; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharmacometrics; modelling; non-linear mixed effects modelling; composite scale data; total score data; total score analysis; precision prediction; bounded integer; bounded integer model; IRT-informed total score analysis; item response theory-informed; mixed models for repeated measures; MMRM; dose-response; dose-response mixed models for repeated measures; DR-MMRM; HbA1c models; fit-for-purpose analysis; clinical trial analysis; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : Clinical trials are needed to evaluate new treatments. In late-stage clinical trials, failures are mostly due to lack of efficacy. Fit-for-purpose analysis methods will likely increase the success rates and advance drug development by providing higher precision to support decisions such as go/no-go, dose selection, or sample size.

  3. 17. Dissecting the Microenvironment of Urothelial Bladder Cancer : Therapy, Modelling and Biomarkers

    Författare :Iliana Kyriaki Kerzeli; Sara Mangsbo; Tania de Gruijl; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Immuno-oncology; Tumor immunology; MALT1 inhibition; Urothelial bladder cancer; Tumor microenvironment; Immunologi; Immunology; Oncology; Onkologi; Urologi; Urology;

    Sammanfattning : The complexity of the tumor microenvironment (TME) impacts therapy responses and the survival of cancer patients. The scope of this thesis is to study the effects of immune modulation on tumor-infiltrating leukocytes, and to explore the TME of urothelial cancer to provide the research society with new knowledge and potential therapeutic targets.

  4. 18. Caspase-3 in lens epithelium

    Författare :Nooshin Talebizadeh; Per Söderberg; Finn Hallböök; Konstantin Galichanin; Michael Wormstone; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ultraviolet radiation; caspase-3; lens; cataract; apoptosis; Immunohistochemistry; spatial distribution; time evolution; modelling; automatic analysis; cell counting; image analysis.; Ophtalmology; Oftalmiatrik;

    Sammanfattning : Purpose: To model the time evolution of active caspase-3 protein expression in a healthy lens, and in a lens exposed to UVR-300 nm (UVR-B). To develop an automated method to classify the fluorescent signal of biomarkers in the lens epithelial cells.Methods: Six-week old Sprague-Dawley rats were used. LÄS MER

  5. 19. Mechanistic Based Pharmacokinetic-Pharmacodynamics models for Drug Interactions and Disease Population Predictions

    Författare :Luna Prieto Garcia; Erik Sjögren; Aleksandra Galetin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiologically-Based Pharmacokinetics; Pharmacokinetics; Pharmacodynamics; Disease Modelling; Drug Interactions; Statins; Mechanistic Modelling; Farmakokinetik och läkemedelsterapi; Pharmacokinetics and Drug Therapy;

    Sammanfattning : Therapeutic dose of a medication refers to the quantity of a drug required to produce a pharmacological effect without causing unacceptable adverse events. Dose selection in the clinical setting is not straight forward due to various factors, including specific patient factors such as age, sex, weight, genetic variants and renal/hepatic function, as well as external factors such as food and co-medication, all of which can influence the efficacy and safety of a drug.

  7. 20. Pharmacometric Methods and Novel Models for Discrete Data

    Författare :Elodie L Plan; Mats O Karlsson; Laura Sargentini-Maier; Armel Stockis; Christian Laveille; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacometrics; pharmacodynamics; disease progression; modelling; discrete data; count; ordered categorical; repeated time-to-event; RTTCE; RCEpT; NONMEM; FOCE; LAPLACE; SAEM; AGQ; pain scores; epilepsy seizures; gastroesophageal symptoms; statistical power; simulations; diagnostics; PHARMACY; FARMACI; Pharmacokinetics and Drug Therapy; Farmakokinetik och läkemedelsterapi;

    Sammanfattning : Pharmacodynamic processes and disease progression are increasingly characterized with pharmacometric models. However, modelling options for discrete-type responses remain limited, although these response variables are commonly encountered clinical endpoints. Types of data defined as discrete data are generally ordinal, e.g. LÄS MER
