16. Deposition and absorption of inhaled drugs
Sammanfattning : Main objectives of this thesis were to evaluate a gamma scintigraphic method used to quantify drug aerosol deposition in the lung, to investigate the influence of two aerosol inhalation parameters on the distribution of inhaled dry powder within the airways, to assess pulmonary absorption kinetics and bioavailability of an inhaled hydrophilic solute in relation to site of deposition, and to assess the influence of a surface active agent (sodium taurocholate, a bile salt) on the deposition and absorption of an inhaled hydrophilic solute. Repeated planar gamma scintigraphy was found to provide the same information on total pulmonary drug deposition as an independent method that involved assessments of urinary drug recovery after blockage of gastrointestinal drug absorption when all of the critical parts of the methodological procedures were accurately and meticulously executed.

18. Leukocyte scintigraphy, SPECT/CT and PET/CT in prosthetic joint infection
Sammanfattning : Background: A known complication of arthroplasty is prosthetic joint infection (PJI). It can be challenging to diagnose and treat PJI due to the formation of a biofilm protecting the bacteria in chronic infections from the innate immune system and antibiotics. LÄS MER
19. Upper gastrointestinal dysmotility - from endocrinological pathogenesis to symptoms
Sammanfattning : Gastrointestinal dysmotility is common, particularly in patients with diabetes mellitus. The aim of this thesis is to explore whether gastrointestinal dysmotility and endocrine secretion are interrelated, and how the symptoms manifest themselves in these patients. LÄS MER
20. Topics in multifractal measures, nonparametrics and biostatistics
Sammanfattning : This thesis consists of four papers. The first two papers, which comprise the main part of the thesis, deal with an unexpected connection between kernel density estimators and dimension spectra for multifractal measures. LÄS MER
