Antigens derived from the mucin MUC1 : Solution and solid-phase synthesis of saccharides, peptides and glycopeptides
Author(s) :
Pudelko, Maciej
Description :
Mucin is a term used to describe a large family of heavily glycosylated proteins which are present on the surfaces of secretory epithelial cells and are overexpressed by many carcinomas. Membrane-bound mucin MUC1 is of special interest. Its backbone consists of repeating units of twenty amino acids ...

Design and Synthesis of Sialic Acid Conjugates as Inhibitors of EKC-causing Adenoviruses
Author(s) :
Johansson, Susanne
Description :
The combat against viral diseases has been, and still is, a major challenge in the field of drug development. Viruses are intracellular parasites that use the host cell ma-chinery for their replication and release. Therefore it is difficult to target and destroy the viral particle without disturbing...

PLE with integrated clean up followed by alternative detection steps for cost-effective analysis of dixons and dioxin-like compounds
Author(s) :
Spinnel, Erik
Description :
Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are two structurally related groups of chemicals, generally referred to as `dioxins´. These are of great concern due to their high toxicity and global spread. Other groups of compounds with similar chemical structure...

Physico-chemical characteristics and quantitative structure-activity relationships of PCBs
Author(s) :
Andersson, Patrik
Description :
The polychlorinated biphenyls (PCBs) comprise a group of 209 congeners varying in the number of chlorine atoms and substitution patterns. These compounds tend to be biomagnified in foodwebs and have been shown to induce an array of effects in exposed organisms. The structural characteristics of the ...

Effects of Varying Combustion Conditions on PCDD/F Formation
Author(s) :
Aurell, Johanna
Description :
Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs) are by-products emitted from combustion sources such as municipal solid waste (MSW) incineration plants. These organic compounds are recognized as toxic, bioaccumulative and persistent in the environment. PCDD/Fs are...

Thermal formation and chlorination of dioxins and dioxin-like compounds
Author(s) :
Jansson, Stina
Description :
This thesis contributes to an increased understanding of the formation of dioxins and dioxin-like compounds in combustion processes. Although emissions to air from waste incineration facilities have been greatly reduced by the use of efficient air pollution control measures, the resulting residues (...

Apoptosis Regulation via the Mitochondrial Pathway : Membrane Response upon Apoptotic Stimuli
Author(s) :
Sani, Marc-Antoine
Description :
The aim of this thesis was the investigation of the mitochondrial response mechanisms upon apoptotic stimuli. The specific objectives were the biophysical characterization of membrane dynamics and the specific roles of lipids in the context of apoptotic regulation occurring at the mitochondrion and ...

Cation adsorption properties of substituted kraft fibres : an experimental and thermodynamic modelling study
Author(s) :
Sundman, Ola
Description :
Acid/base and metal ion adsorption properties have been investigated for a range of chemically modified bleached Kraft fibre materials (pulps). The studies were performed via potentiometric titrations, Flame Atomic Absorbtion (and Emission) Spectroscopy, Inductively Coupled Plasma Optical Emission S...

Use and Development of Diffusive Samplers to Analyse the Fate of Polycyclic Aromatic Compounds, Polychlorinated Biphenyls and Pharmaceuticals in Wastewater Treatment Processes
Author(s) :
Augulyte, Lijana
Description :
The efficiency of wastewater treatment systems is commonly measured by the reductions of parameters such as biological oxygen demand (BOD), chemical oxygen demand (COD) and total suspended solids (TSS) and/or reductions in levels of selected macro compounds (e.g. long-chained hydrocarbons and inorga...

New approaches to moisture determination in complex matrices based on the Karl Fischer Reaction in methanolic and non-alcoholic media
Author(s) :
Larsson, William
Description :
Vattenhaltsbestämning är av stor vikt i många sammanhang. T.ex. kan vattenhalten påverka utbytet av en kemisk syntes, eller ha negativ inverkan på hållbarheten av läkemedel och livsmedel. Standardmetoden för vattenhaltsbestämning är Karl Fischer-titrering, baserad på antingen volymetri eller coulome...
